Description

 

Jewel bugs are small to medium-sized oval-shaped bugs with a body length averaging at 5 to 20 mm (0.20 to 0.79 in). They can easily be distinguished from stink bugs (Pentatomidae) because the shield-like enlarged last section of their thorax (known as the scutellum, Latin for "little shield") completely covers the abdomen and the wings.

 

Despite their resemblance to beetles, jewel bugs are hemipterans or true bugs. The scutellum is an extension of the thorax, unlike the elytra of beetles which are hardened forewings. As such, jewel bugs have four membranous wings underneath the scutellum in contrast to two in beetles.[6] The scutellum in jewel bugs also does not have a division in the middle and thus does not 'split open' when they take flight like in beetles.

 

The heads of jewel bugs are triangular and the antennae have three to five segments. Like all heteropterans, jewel bugs are characterized by a segmented beak-like mouthpart (known as the rostrum). During feeding, jewel bugs inject proteolytic enzymes in their saliva into plants, digesting plant matter into a liquid form which they then suck up. The tarsus has three segments (tarsomeres).

 

Colors

 

Though some species are quite drab, the most conspicuous jewel bugs are often brilliantly colored, exhibiting a wide range of iridescent metallic hues that change with the view angle. The colors are the result of a combination of factors. Some species like Chrsyocoris stockerus and Scutellera nobilis display colors from multiple thin layers of pigmented chitin. The colors often change or become duller when the specimens are dried, due to the topmost chitinous layer becoming opaque and obscuring the colors of the bottom layer. The colors can be restored by moistening the surfaces with water.

 

Iridescence (or goniochromism) in jewel bugs like Poecilocoris lewisi are the result of structural coloration. Instead of pigments, the colors are caused by the interference, diffraction, or scattering of light by numerous tiny structures.

 

In Poecilocoris lewisi, multiple tiny conical protuberances around 900 nm in height and averaging at a diameter of 360 nm are scattered on the epicuticle. These structures affect light passing through them, producing their oily-looking blue sheen (known as the Tyndall effect or Mie scattering).

 

In other species like the African shield bug (Calidea panaethiopica), the dorsal cuticle is dotted with tiny regularly spaced hemispherical cavities. The depressions act like Bragg mirrors. When light hits the pitted surface, it gives off multiple reflections resulting in the distinctive two tone yellow-blue iridescence.

 

The colors and patterns on jewel bugs can vary significantly between instars and even within adults of a species.

 

Jewel bugs are also known to mimic the colors, patterns, and shape of other organisms for defensive purposes. An example is the yellow-spotted black Steganocerus multipunctatus which exhibits Müllerian mimicry with the tortoise beetle Chiridopsis suffriani.

This photo was taken on the Milford Track, a 4-day / 3-night walk in northern Fiordland, on New Zealand's South Island.

 

Wet? Well, yes.

 

To get things into perspective, you have to know that the nearby town of Milford received a mean of 6.75 metres of rain per year between 1971 and 2000. We were frequently told that the Milford track area gets around 7m a year, while some of the western slopes of the mountains in Fiordland get up to 9m. The day before this photo was taken, we spent much of the walk being refreshed by most of the day's near-negligible 214mm, of which 40mm fell in one 30-minute period.

 

Measuring rainfall in metres may seem quaint; and yet Fiordland is positively parched by comparison with some of the soggier parts of the world.

 

Lloro in Columbia is thought to get 13m a year, though this is a modelled figure that has never been measured.

Mount Wai‘ale‘ale, on the Hawai'an island of Kauai, gets 11.5 to 13m a year.

Mawsynram, in north-eastern India, receives 11.9m annually.

Mount Tutenendo in Columbia gets 12m a year.

Cherrapunji, near Mawsynram, gets 11m a year – almost all of it between June and August. It holds the record for the wettest 6 months ever recorded, with 22.5m between April and September 1861. In July that year 9.3m fell, making it the wettest month ever recorded anywhere.

Debundscha in Cameroon gets 10m a year.

Quibdo in Columbia gets 9m.

Bellenden Ker, in Queensland, Australia, gets 8.6m a year.

And last among these sodden spots, Andagoya in Colombia gets 7m. All of the above are towns and villages; Fiordland is a wonderful wilderness.

 

The most rain ever recorded in a 3-day period – 3.9m – is held by La Réunion. Now that's wet.

 

It rained and rained and rained and rained,

The average fall was well maintained,

And when the tracks were simply bogs

It started raining cats and dogs.

 

After a drought of half an hour

we had a most refreshing shower,

then the most curious thing of all:

a gentle rain began to fall.

 

Next day was also fairly dry

save for the deluge from the sky

which wet the party to the skin:

and after that, the rain set in.

 

This poem is found in many websites in a variety of slightly different versions. On those sites, it is variously linked with the west coast of Scotland and with the west coast of New Zealand's South Island. Setting aside those few individuals who pass it off as their own invention, is invariably attributed to "Anon", with associated dates often in the 1980s. I first saw it framed on the wall of a mountain hut on the Millford Track, where it is attributed to an anonymous tramper who left it there in 1989.

 

I have found one source that may be the root of it all. A certain Ho-Fang, from what must then have been the villagethe city (sorry, Nelson - see Andrew's comment under this shot) of Nelson (located in the north of South Island), published it on 15 September 1931, under the title West Coast Weather in the Otautau Standard and Wallace County Chronicle, Volume XXVII, Issue 1336, where it was printed on page 3.

 

"Fang" is quite a common family name in China and Taiwan, so the author might be Chinese, though in normal Chinese usage the given name, "Ho", would follow the family name. Somehow it sounds like a nom de plume. I can't find any obvious name for which this would be an anagram, though.

 

There is something about Ho-Fang's printed introduction to the poem that does not quite ring true, and I wonder whether Ho-Fang cribbed it from some earlier source - perhaps (who knows?) even from some saturated scribbler in Scotland.

 

Scotland? Saturated? Kinlochewe, the wettest met station in Scotland, gets a paltry 2.2m a year. Almost sahelian, if you ask me.

 

A B&W conversion.

Hyderabad (Listeni/ˈhaɪdərəˌbæd/ HY-dər-ə-bad; often /ˈhaɪdrəˌbæd/) is the capital of the southern Indian state of Telangana and de jure capital of Andhra Pradesh. Occupying 625 square kilometres along the banks of the Musi River, it has a population of about 6.8 million and a metropolitan population of about 7.75 million, making it the fourth most populous city and sixth most populous urban agglomeration in India. At an average altitude of 542 metres, much of Hyderabad is situated on hilly terrain around artificial lakes, including Hussain Sagar - predating the city's founding - north of the city centre.

 

Established in 1591 by Muhammad Quli Qutb Shah, Hyderabad remained under the rule of the Qutb Shahi dynasty for nearly a century before the Mughals captured the region. In 1724, Mughal viceroy Asif Jah I declared his sovereignty and created his own dynasty, known as the Nizams of Hyderabad. The Nizam's dominions became a princely state during the British Raj, and remained so for 150 years, with the city serving as its capital. The city continued as the capital of Hyderabad State after it was brought into the Indian Union in 1948, and became the capital of Andhra Pradesh after the States Reorganisation Act, 1956. Since 1956, Rashtrapati Nilayam in the city has been the winter office of the President of India. In 2014, the newly formed state of Telangana split from Andhra Pradesh and the city became joint capital of the two states, a transitional arrangement scheduled to end by 2025.

 

Relics of Qutb Shahi and Nizam rule remain visible today, with the Charminar - commissioned by Muhammad Quli Qutb Shah - coming to symbolise Hyderabad. Golconda fort is another major landmark. The influence of Mughlai culture is also evident in the city's distinctive cuisine, which includes Hyderabadi biryani and Hyderabadi haleem. The Qutb Shahis and Nizams established Hyderabad as a cultural hub, attracting men of letters from different parts of the world. Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire in the mid-19th century, with artists migrating to the city from the rest of the Indian subcontinent. While Hyderabad is losing its cultural pre-eminence, it is today, due to the Telugu film industry, the country's second-largest producer of motion pictures.

 

Hyderabad was historically known as a pearl and diamond trading centre, and it continues to be known as the City of Pearls. Many of the city's traditional bazaars, including Laad Bazaar, Begum Bazaar and Sultan Bazaar, have remained open for centuries. However, industrialisation throughout the 20th century attracted major Indian manufacturing, research and financial institutions, including Bharat Heavy Electricals Limited, the National Geophysical Research Institute and the Centre for Cellular and Molecular Biology. Special economic zones dedicated to information technology have encouraged companies from across India and around the world to set up operations and the emergence of pharmaceutical and biotechnology industries in the 1990s led to the area's naming as India's "Genome Valley". With an output of US$74 billion, Hyderabad is the fifth-largest contributor to India's overall gross domestic product.

 

HISTORY

TOPONYMY

According to John Everett-Heath, the author of Oxford Concise Dictionary of World Place Names, Hyderabad means "Haydar's city" or "lion city", from haydar (lion) and ābād (city). It was named to honour the Caliph Ali Ibn Abi Talib, who was also known as Haydar because of his lion-like valour in battles. Andrew Petersen, a scholar of Islamic architecture, says the city was originally called Baghnagar (city of gardens). One popular theory suggests that Muhammad Quli Qutb Shah, the founder of the city, named it "Bhaganagar" or "Bhāgnagar" after Bhagmati, a local nautch (dancing) girl with whom he had fallen in love. She converted to Islam and adopted the title Hyder Mahal. The city was renamed Hyderabad in her honour. According to another source, the city was named after Haidar, the son of Quli Qutb Shah.

 

EARLY AND MEDIEVAL HISTORY

Archaeologists excavating near the city have unearthed Iron Age sites that may date from 500 BCE. The region comprising modern Hyderabad and its surroundings was known as Golkonda ("shepherd's hill"), and was ruled by the Chalukya dynasty from 624 CE to 1075 CE. Following the dissolution of the Chalukya empire into four parts in the 11th century, Golkonda came under the control of the Kakatiya dynasty from 1158, whose seat of power was at Warangal, 148 km northeast of modern Hyderabad.

 

The Kakatiya dynasty was reduced to a vassal of the Khilji dynasty in 1310 after its defeat by Sultan Alauddin Khilji of the Delhi Sultanate. This lasted until 1321, when the Kakatiya dynasty was annexed by Malik Kafur, Allaudin Khilji's general. During this period, Alauddin Khilji took the Koh-i-Noor diamond, which is said to have been mined from the Kollur Mines of Golkonda, to Delhi. Muhammad bin Tughluq succeeded to the Delhi sultanate in 1325, bringing Warangal under the rule of the Tughlaq dynasty until 1347 when Ala-ud-Din Bahman Shah, a governor under bin Tughluq, rebelled against Delhi and established the Bahmani Sultanate in the Deccan Plateau, with Gulbarga, 200 km west of Hyderabad, as its capital. The Bahmani kings ruled the region until 1518 and were the first independent Muslim rulers of the Deccan.

 

Sultan Quli, a governor of Golkonda, revolted against the Bahmani Sultanate and established the Qutb Shahi dynasty in 1518; he rebuilt the mud-fort of Golconda and named the city "Muhammad nagar". The fifth sultan, Muhammad Quli Qutb Shah, established Hyderabad on the banks of the Musi River in 1591, to avoid the water shortages experienced at Golkonda. During his rule, he had the Charminar and Mecca Masjid built in the city. On 21 September 1687, the Golkonda Sultanate came under the rule of the Mughal emperor Aurangzeb after a year-long siege of the Golkonda fort. The annexed area was renamed Deccan Suba (Deccan province) and the capital was moved from Golkonda to Aurangabad, about 550 km northwest of Hyderabad.

 

MODERN HISTORY

In 1713 Farrukhsiyar, the Mughal emperor, appointed Asif Jah I to be Viceroy of the Deccan, with the title Nizam-ul-Mulk (Administrator of the Realm). In 1724, Asif Jah I defeated Mubariz Khan to establish autonomy over the Deccan Suba, named the region Hyderabad Deccan, and started what came to be known as the Asif Jahi dynasty. Subsequent rulers retained the title Nizam ul-Mulk and were referred to as Asif Jahi Nizams, or Nizams of Hyderabad. The death of Asif Jah I in 1748 resulted in a period of political unrest as his sons, backed by opportunistic neighbouring states and colonial foreign forces, contended for the throne. The accession of Asif Jah II, who reigned from 1762 to 1803, ended the instability. In 1768 he signed the treaty of Masulipatnam, surrendering the coastal region to the East India Company in return for a fixed annual rent.

 

In 1769 Hyderabad city became the formal capital of the Nizams. In response to regular threats from Hyder Ali (Dalwai of Mysore), Baji Rao I (Peshwa of the Maratha Empire), and Basalath Jung (Asif Jah II's elder brother, who was supported by the Marquis de Bussy-Castelnau), the Nizam signed a subsidiary alliance with the East India Company in 1798, allowing the British Indian Army to occupy Bolarum (modern Secunderabad) to protect the state's borders, for which the Nizams paid an annual maintenance to the British.

 

Until 1874 there were no modern industries in Hyderabad. With the introduction of railways in the 1880s, four factories were built to the south and east of Hussain Sagar lake, and during the early 20th century, Hyderabad was transformed into a modern city with the establishment of transport services, underground drainage, running water, electricity, telecommunications, universities, industries, and Begumpet Airport. The Nizams ruled their princely state from Hyderabad during the British Raj.

 

After India gained independence, the Nizam declared his intention to remain independent rather than become part of the Indian Union. The Hyderabad State Congress, with the support of the Indian National Congress and the Communist Party of India, began agitating against Nizam VII in 1948. On 17 September that year, the Indian Army took control of Hyderabad State after an invasion codenamed Operation Polo. With the defeat of his forces, Nizam VII capitulated to the Indian Union by signing an Instrument of Accession, which made him the Rajpramukh (Princely Governor) of the state until 31 October 1956. Between 1946 and 1951, the Communist Party of India fomented the Telangana uprising against the feudal lords of the Telangana region. The Constitution of India, which became effective on 26 January 1950, made Hyderabad State one of the part B states of India, with Hyderabad city continuing to be the capital. In his 1955 report Thoughts on Linguistic States, B. R. Ambedkar, then chairman of the Drafting Committee of the Indian Constitution, proposed designating the city of Hyderabad as the second capital of India because of its amenities and strategic central location. Since 1956, the Rashtrapati Nilayam in Hyderabad has been the second official residence and business office of the President of India; the President stays once a year in winter and conducts official business particularly relating to Southern India.

 

On 1 November 1956 the states of India were reorganised by language. Hyderabad state was split into three parts, which were merged with neighbouring states to form the modern states of Maharashtra, Karnataka and Andhra Pradesh. The nine Telugu- and Urdu-speaking districts of Hyderabad State in the Telangana region were merged with the Telugu-speaking Andhra State to create Andhra Pradesh,with Hyderabad as its capital. Several protests, known collectively as the Telangana movement, attempted to invalidate the merger and demanded the creation of a new Telangana state. Major actions took place in 1969 and 1972, and a third began in 2010. The city suffered several explosions: one at Dilsukhnagar in 2002 claimed two lives; terrorist bombs in May and August 2007 caused communal tension and riots; and two bombs exploded in February 2013. On 30 July 2013 the United Progressive Alliance (UPA) government of India declared that part of Andhra Pradesh would be split off to form a new Telangana state, and that Hyderabad city would be the capital city and part of Telangana, while the city would also remain the capital of Andhra Pradesh for no more than ten years. On 3 October 2013 the Union Cabinet approved the proposal, and in February 2014 both houses of Parliament passed the Telangana Bill. With the final assent of the President of India in June 2014, Telangana state was formed.

 

GEOGRAPHY

TOPOGRAPHY

Situated in the southern part of Telangana in southeastern India, Hyderabad is 1,566 kilometres south of Delhi, 699 kilometres southeast of Mumbai, and 570 kilometres north of Bangalore by road. It lies on the banks of the Musi River, in the northern part of the Deccan Plateau. Greater Hyderabad covers 625 km2, making it one of the largest metropolitan areas in India. With an average altitude of 542 metres, Hyderabad lies on predominantly sloping terrain of grey and pink granite, dotted with small hills, the highest being Banjara Hills at 672 metres. The city has numerous lakes referred to as sagar, meaning "sea". Examples include artificial lakes created by dams on the Musi, such as Hussain Sagar (built in 1562 near the city centre), Osman Sagar and Himayat Sagar. As of 1996, the city had 140 lakes and 834 water tanks (ponds).

 

CLIMATE

Hyderabad has a tropical wet and dry climate (Köppen Aw) bordering on a hot semi-arid climate (Köppen BSh). The annual mean temperature is 26.6 °C; monthly mean temperatures are 21–33 °C. Summers (March–June) are hot and humid, with average highs in the mid-to-high 30s Celsius; maximum temperatures often exceed 40 °C between April and June. The coolest temperatures occur in December and January, when the lowest temperature occasionally dips to 10 °C. May is the hottest month, when daily temperatures range from 26 to 39 °C; December, the coldest, has temperatures varying from 14.5 to 28 °C.

 

Heavy rain from the south-west summer monsoon falls between June and September, supplying Hyderabad with most of its mean annual rainfall. Since records began in November 1891, the heaviest rainfall recorded in a 24-hour period was 241.5 mm on 24 August 2000. The highest temperature ever recorded was 45.5 °C on 2 June 1966, and the lowest was 6.1 °C on 8 January 1946. The city receives 2,731 hours of sunshine per year; maximum daily sunlight exposure occurs in February.

 

CONSERVATION

Hyderabad's lakes and the sloping terrain of its low-lying hills provide habitat for an assortment of flora and fauna. The forest region in and around the city encompasses areas of ecological and biological importance, which are preserved in the form of national parks, zoos, mini-zoos and a wildlife sanctuary. Nehru Zoological Park, the city's one large zoo, is the first in India to have a lion and tiger safari park. Hyderabad has three national parks (Mrugavani National Park, Mahavir Harina Vanasthali National Park and Kasu Brahmananda Reddy National Park), and the Manjira Wildlife Sanctuary is about 50 km from the city. Hyderabad's other environmental reserves are: Kotla Vijayabhaskara Reddy Botanical Gardens, Shamirpet Lake, Hussain Sagar, Fox Sagar Lake, Mir Alam Tank and Patancheru Lake, which is home to regional birds and attracts seasonal migratory birds from different parts of the world. Organisations engaged in environmental and wildlife preservation include the Telangana Forest Department, Indian Council of Forestry Research and Education, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the Animal Welfare Board of India, the Blue Cross of Hyderabad and the University of Hyderabad.

 

ADMINISTRATION

COMMON CAPITAL OF TELANGANA AND ANDHRA PRADESH

According to the Andhra Pradesh Reorganisation Act, 2014 part 2 Section 5: "On and from the appointed day, Hyderabad in the existing State of Andhra Pradesh, shall be the common capital of the State of Telangana and the State of Andhra Pradesh for such period not exceeding ten years. After expiry of the period referred to in sub-section, Hyderabad shall be the capital of the State of Telangana and there shall be a new capital for the State of Andhra Pradesh."

 

The same sections also define that the common capital includes the existing area designated as the Greater Hyderabad Municipal Corporation under the Hyderabad Municipal Corporation Act, 1955. As stipulated in sections 3 and 18 of the Reorganisation Act, city MLAs are members of Telangana state assembly.

 

LOCAL GOVERNMENT

The Greater Hyderabad Municipal Corporation (GHMC) oversees the civic infrastructure of the city's 18 "circles", which together encompass 150 municipal wards. Each ward is represented by a corporator, elected by popular vote. The corporators elect the Mayor, who is the titular head of GHMC; executive powers rest with the Municipal Commissioner, appointed by the state government. The GHMC carries out the city's infrastructural work such as building and maintenance of roads and drains, town planning including construction regulation, maintenance of municipal markets and parks, solid waste management, the issuing of birth and death certificates, the issuing of trade licences, collection of property tax, and community welfare services such as mother and child healthcare, and pre-school and non-formal education. The GHMC was formed in April 2007 by merging the Municipal Corporation of Hyderabad (MCH) with 12 municipalities of the Hyderabad, Ranga Reddy and Medak districts covering a total area of 625 km2. In the 2009 municipal election, an alliance of the Indian National Congress and Majlis-e-Ittehadul Muslimeen formed the majority. The Secunderabad Cantonment Board is a civic administration agency overseeing an area of 40.1 km2, where there are several military camps. The Osmania University campus is administered independently by the university authority.

 

Law and order in Hyderabad city is supervised by the governor of Telangana. The jurisdiction is divided into two police commissionerates: Hyderabad and Cyberabad, which are again divided into four and five police zones respectively. Each zone is headed by a deputy commissioner.

 

The jurisdictions of the city's administrative agencies are, in ascending order of size: the Hyderabad Police area, Hyderabad district, the GHMC area ("Hyderabad city") and the area under the Hyderabad Metropolitan Development Authority (HMDA). The HMDA is an apolitical urban planning agency that covers the GHMC and its suburbs, extending to 54 mandals in five districts encircling the city. It coordinates the development activities of GHMC and suburban municipalities and manages the administration of bodies such as the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB).

 

As the seat of the government of Telangana, Hyderabad is home to the state's legislature, secretariat and high court, as well as various local government agencies. The Lower City Civil Court and the Metropolitan Criminal Court are under the jurisdiction of the High Court. The GHMC area contains 24 State Legislative Assembly constituencies, which form five constituencies of the Lok Sabha (the lower house of the Parliament of India).

 

UTILITY SERVICES

The HMWSSB regulates rainwater harvesting, sewerage services and water supply, which is sourced from several dams located in the suburbs. In 2005, the HMWSSB started operating a 116-kilometre-long water supply pipeline from Nagarjuna Sagar Dam to meet increasing demand. The Telangana Southern Power Distribution Company Limited manages electricity supply. As of October 2014, there were 15 fire stations in the city, operated by the Telangana State Disaster and Fire Response Department. The government-owned India Post has five head post offices and many sub-post offices in Hyderabad, which are complemented by private courier services.

 

POLLUTION CONTROL

Hyderabad produces around 4,500 tonnes of solid waste daily, which is transported from collection units in Imlibun, Yousufguda and Lower Tank Bund to the dumpsite in Jawaharnagar. Disposal is managed by the Integrated Solid Waste Management project which was started by the GHMC in 2010. Rapid urbanisation and increased economic activity has also led to increased industrial waste, air, noise and water pollution, which is regulated by the Telangana Pollution Control Board (TPCB). The contribution of different sources to air pollution in 2006 was: 20–50% from vehicles, 40–70% from a combination of vehicle discharge and road dust, 10–30% from industrial discharges and 3–10% from the burning of household rubbish. Deaths resulting from atmospheric particulate matter are estimated at 1,700–3,000 each year. Ground water around Hyderabad, which has a hardness of up to 1000 ppm, around three times higher than is desirable, is the main source of drinking water but the increasing population and consequent increase in demand has led to a decline in not only ground water but also river and lake levels. This shortage is further exacerbated by inadequately treated effluent discharged from industrial treatment plants polluting the water sources of the city.

 

HEALTHCARE

The Commissionerate of Health and Family Welfare is responsible for planning, implementation and monitoring of all facilities related to health and preventive services. As of 2010–11, the city had 50 government hospitals, 300 private and charity hospitals and 194 nursing homes providing around 12,000 hospital beds, fewer than half the required 25,000. For every 10,000 people in the city, there are 17.6 hospital beds, 9 specialist doctors, 14 nurses and 6 physicians. The city also has about 4,000 individual clinics and 500 medical diagnostic centres. Private clinics are preferred by many residents because of the distance to, poor quality of care at and long waiting times in government facilities, despite the high proportion of the city's residents being covered by government health insurance: 24% according to a National Family Health Survey in 2005. As of 2012, many new private hospitals of various sizes were opened or being built. Hyderabad also has outpatient and inpatient facilities that use Unani, homeopathic and Ayurvedic treatments.

 

In the 2005 National Family Health Survey, it was reported that the city's total fertility rate is 1.8, which is below the replacement rate. Only 61% of children had been provided with all basic vaccines (BCG, measles and full courses of polio and DPT), fewer than in all other surveyed cities except Meerut. The infant mortality rate was 35 per 1,000 live births, and the mortality rate for children under five was 41 per 1,000 live births. The survey also reported that a third of women and a quarter of men are overweight or obese, 49% of children below 5 years are anaemic, and up to 20% of children are underweight, while more than 2% of women and 3% of men suffer from diabetes.

 

DEMOGRAPHICS

When the GHMC was created in 2007, the area occupied by the municipality increased from 175 km2 to 625 km2. Consequently, the population increased by 87%, from 3,637,483 in the 2001 census to 6,809,970 in the 2011 census, 24% of which are migrants from elsewhere in India, making Hyderabad the nation's fourth most populous city. As of 2011, the population density is 18,480/km2. At the same 2011 census, the Hyderabad Urban Agglomeration had a population of 7,749,334, making it the sixth most populous urban agglomeration in the country. The population of the Hyderabad urban agglomeration has since been estimated by electoral officials to be 9.1 million as of early 2013 but is expected to exceed 10 million by the end of the year. There are 3,500,802 male and 3,309,168 female citizens - a sex ratio of 945 females per 1000 males, higher than the national average of 926 per 1000. Among children aged 0–6 years, 373,794 are boys and 352,022 are girls - a ratio of 942 per 1000. Literacy stands at 82.96% (male 85.96%; female 79.79%), higher than the national average of 74.04%. The socio-economic strata consist of 20% upper class, 50% middle class and 30% working class.

 

ETHNIC GROUPS, LANGUAGE AND RELIGION

Referred to as "Hyderabadi", residents of Hyderabad are predominantly Telugu and Urdu speaking people, with minority Bengali, Gujarati (including Memon), Kannada (including Nawayathi), Malayalam, Marathi, Marwari, Odia, Punjabi, Tamil and Uttar Pradeshi communities. Hadhrami Arabs, African Arabs, Armenians, Abyssinians, Iranians, Pathans and Turkish people are also present; these communities, of which the Hadhrami are the largest, declined after Hyderabad State became part of the Indian Union, as they lost the patronage of the Nizams.

 

Telugu is the official language of Hyderabad and Urdu is its second language. The Telugu dialect spoken in Hyderabad is called Telangana, and the Urdu spoken is called Dakhani. English is also used. A significant minority speak other languages, including Hindi, Marathi, Odia, Tamil, Bengali and Kannada.

 

Hindus are in the majority. Muslims are present throughout the city and predominate in and around the Old City. There are also Christian, Sikh, Jain, Buddhist and Parsi communities and iconic temples, mosques and churches can be seen. According to the 2001 census, Hyderabad district's religious make-up was: Hindus (55.41%), Muslims (41.17%), Christians (2.43%), Jains (0.43%), Sikhs (0.29%) and Buddhists (0.02%); 0.23% did not state any religion.

 

SLUMS

In the greater metropolitan area, 13% of the population live below the poverty line. According to a 2012 report submitted by GHMC to the World Bank, Hyderabad has 1,476 slums with a total population of 1.7 million, of whom 66% live in 985 slums in the "core" of the city (the part that formed Hyderabad before the April 2007 expansion) and the remaining 34% live in 491 suburban tenements. About 22% of the slum-dwelling households had migrated from different parts of India in the last decade of the 20th century, and 63% claimed to have lived in the slums for more than 10 years. Overall literacy in the slums is 60–80% and female literacy is 52–73%. A third of the slums have basic service connections, and the remainder depend on general public services provided by the government. There are 405 government schools, 267 government aided schools, 175 private schools and 528 community halls in the slum areas. According to a 2008 survey by the Centre for Good Governance, 87.6% of the slum-dwelling households are nuclear families, 18% are very poor, with an income up to ₹20000 (US$300) per annum, 73% live below the poverty line (a standard poverty line recognised by the Andhra Pradesh Government is ₹24000 (US$360) per annum), 27% of the chief wage earners (CWE) are casual labour and 38% of the CWE are illiterate. About 3.72% of the slum children aged 5–14 do not go to school and 3.17% work as child labour, of whom 64% are boys and 36% are girls. The largest employers of child labour are street shops and construction sites. Among the working children, 35% are engaged in hazardous jobs.

 

NEIGHBOURHOODS

The historic city established by Muhammad Quli Qutb Shah on the southern side of the Musi River forms the "Old City", while the "New City" encompasses the urbanised area on the northern banks. The two are connected by many bridges across the river, the oldest of which is Purana Pul ("old bridge"). Hyderabad is twinned with neighbouring Secunderabad, to which it is connected by Hussain Sagar.

 

Many historic and tourist sites lie in south central Hyderabad, such as the Charminar, the Mecca Masjid, the Salar Jung Museum, the Nizam's Museum, the Falaknuma Palace, and the traditional retail corridor comprising the Pearl Market, Laad Bazaar and Madina Circle. North of the river are hospitals, colleges, major railway stations and business areas such as Begum Bazaar, Koti, Abids, Sultan Bazaar and Moazzam Jahi Market, along with administrative and recreational establishments such as the Reserve Bank of India, the Telangana Secretariat, the Hyderabad Mint, the Telangana Legislature, the Public Gardens, the Nizam Club, the Ravindra Bharathi, the State Museum, the Birla Temple and the Birla Planetarium.

 

North of central Hyderabad lie Hussain Sagar, Tank Bund Road, Rani Gunj and the Secunderabad Railway Station. Most of the city's parks and recreational centres, such as Sanjeevaiah Park, Indira Park, Lumbini Park, NTR Gardens, the Buddha statue and Tankbund Park are located here. In the northwest part of the city there are upscale residential and commercial areas such as Banjara Hills, Jubilee Hills, Begumpet, Khairatabad and Miyapur. The northern end contains industrial areas such as Sanathnagar, Moosapet, Balanagar, Patancheru and Chanda Nagar. The northeast end is dotted with residential areas. In the eastern part of the city lie many defence research centres and Ramoji Film City. The "Cyberabad" area in the southwest and west of the city has grown rapidly since the 1990s. It is home to information technology and bio-pharmaceutical companies and to landmarks such as Hyderabad Airport, Osman Sagar, Himayath Sagar and Kasu Brahmananda Reddy National Park.

 

LANDMARKS

Heritage buildings constructed during the Qutb Shahi and Nizam eras showcase Indo-Islamic architecture influenced by Medieval, Mughal and European styles. After the 1908 flooding of the Musi River, the city was expanded and civic monuments constructed, particularly during the rule of Mir Osman Ali Khan (the VIIth Nizam), whose patronage of architecture led to him being referred to as the maker of modern Hyderabad. In 2012, the government of India declared Hyderabad the first "Best heritage city of India".

 

Qutb Shahi architecture of the 16th and early 17th centuries followed classical Persian architecture featuring domes and colossal arches. The oldest surviving Qutb Shahi structure in Hyderabad is the ruins of Golconda fort built in the 16th century. The Charminar, Mecca Masjid, Charkaman and Qutb Shahi tombs are other existing structures of this period. Among these the Charminar has become an icon of the city; located in the centre of old Hyderabad, it is a square structure with sides 20 m long and four grand arches each facing a road. At each corner stands a 56 m-high minaret. Most of the historical bazaars that still exist were constructed on the street north of Charminar towards Golconda fort. The Charminar, Qutb Shahi tombs and Golconda fort are considered to be monuments of national importance in India; in 2010 the Indian government proposed that the sites be listed for UNESCO World Heritage status.

 

Among the oldest surviving examples of Nizam architecture in Hyderabad is the Chowmahalla Palace, which was the seat of royal power. It showcases a diverse array of architectural styles, from the Baroque Harem to its Neoclassical royal court. The other palaces include Falaknuma Palace (inspired by the style of Andrea Palladio), Purani Haveli, King Kothi and Bella Vista Palace all of which were built at the peak of Nizam rule in the 19th century. During Mir Osman Ali Khan's rule, European styles, along with Indo-Islamic, became prominent. These styles are reflected in the Falaknuma Palace and many civic monuments such as the Hyderabad High Court, Osmania Hospital, Osmania University, the State Central Library, City College, the Telangana Legislature, the State Archaeology Museum, Jubilee Hall, and Hyderabad and Kachiguda railway stations. Other landmarks of note are Paigah Palace, Asman Garh Palace, Basheer Bagh Palace, Errum Manzil and the Spanish Mosque, all constructed by the Paigah family.

 

ECONOMY

Hyderabad is the largest contributor to the gross domestic product (GDP), tax and other revenues, of Telangana, and the sixth largest deposit centre and fourth largest credit centre nationwide, as ranked by the Reserve Bank of India (RBI) in June 2012. Its US$74 billion GDP made it the fifth-largest contributor city to India's overall GDP in 2011–12. Its per capita annual income in 2011 was ₹44300 (US$670). As of 2006, the largest employers in the city were the governments of Andhra Pradesh (113,098 employees) and India (85,155). According to a 2005 survey, 77% of males and 19% of females in the city were employed. The service industry remains dominant in the city, and 90% of the employed workforce is engaged in this sector.

 

Hyderabad's role in the pearl trade has given it the name "City of Pearls" and up until the 18th century, the city was also the only global trading centre for large diamonds. Industrialisation began under the Nizams in the late 19th century, helped by railway expansion that connected the city with major ports. From the 1950s to the 1970s, Indian enterprises, such as Bharat Heavy Electricals Limited (BHEL), Nuclear Fuel Complex (NFC), National Mineral Development Corporation (NMDC), Bharat Electronics (BEL), Electronics Corporation of India Limited (ECIL), Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL), Centre for Cellular and Molecular Biology (CCMB), Centre for DNA Fingerprinting and Diagnostics (CDFD), State Bank of Hyderabad (SBH) and Andhra Bank (AB) were established in the city. The city is home to Hyderabad Securities formerly known as Hyderabad Stock Exchange (HSE), and houses the regional office of the Securities and Exchange Board of India (SEBI). In 2013, the Bombay Stock Exchange (BSE) facility in Hyderabad was forecasted to provide operations and transactions services to BSE-Mumbai by the end of 2014. The growth of the financial services sector has helped Hyderabad evolve from a traditional manufacturing city to a cosmopolitan industrial service centre. Since the 1990s, the growth of information technology (IT), IT-enabled services (ITES), insurance and financial institutions has expanded the service sector, and these primary economic activities have boosted the ancillary sectors of trade and commerce, transport, storage, communication, real estate and retail.

 

Hyderabad's commercial markets are divided into four sectors: central business districts, sub-central business centres, neighbourhood business centres and local business centres. Many traditional and historic bazaars are located throughout the city, Laad Bazaar being the prominent among all is popular for selling a variety of traditional and cultural antique wares, along with gems and pearls.

 

The establishment of Indian Drugs and Pharmaceuticals Limited (IDPL), a public sector undertaking, in 1961 was followed over the decades by many national and global companies opening manufacturing and research facilities in the city. As of 2010, the city manufactured one third of India's bulk drugs and 16% of biotechnology products, contributing to its reputation as "India's pharmaceutical capital" and the "Genome Valley of India". Hyderabad is a global centre of information technology, for which it is known as Cyberabad (Cyber City). As of 2013, it contributed 15% of India's and 98% of Andhra Pradesh's exports in IT and ITES sectors and 22% of NASSCOM's total membership is from the city. The development of HITEC City, a township with extensive technological infrastructure, prompted multinational companies to establish facilities in Hyderabad. The city is home to more than 1300 IT and ITES firms, including global conglomerates such as Microsoft (operating its largest R&D campus outside the US), Google, IBM, Yahoo!, Dell, Facebook, and major Indian firms including Tech Mahindra, Infosys, Tata Consultancy Services (TCS), Polaris and Wipro. In 2009 the World Bank Group ranked the city as the second best Indian city for doing business. The city and its suburbs contain the highest number of special economic zones of any Indian city.

 

Like the rest of India, Hyderabad has a large informal economy that employs 30% of the labour force. According to a survey published in 2007, it had 40–50,000 street vendors, and their numbers were increasing. Among the street vendors, 84% are male and 16% female, and four fifths are "stationary vendors" operating from a fixed pitch, often with their own stall. Most are financed through personal savings; only 8% borrow from moneylenders. Vendor earnings vary from ₹50 (75¢ US) to ₹800 (US$12) per day. Other unorganised economic sectors include dairy, poultry farming, brick manufacturing, casual labour and domestic help. Those involved in the informal economy constitute a major portion of urban poor.

 

CULTURE

Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire. After the fall of Delhi in 1857, the migration of performing artists to the city particularly from the north and west of the Indian sub continent, under the patronage of the Nizam, enriched the cultural milieu. This migration resulted in a mingling of North and South Indian languages, cultures and religions, which has since led to a co-existence of Hindu and Muslim traditions, for which the city has become noted. A further consequence of this north–south mix is that both Telugu and Urdu are official languages of Telangana.[164] The mixing of religions has also resulted in many festivals being celebrated in Hyderabad such as Ganesh Chaturthi, Diwali and Bonalu of Hindu tradition and Eid ul-Fitr and Eid al-Adha by Muslims.

 

Traditional Hyderabadi garb also reveals a mix of Muslim and South Asian influences with men wearing sherwani and kurta - paijama and women wearing khara dupatta and salwar kameez. Muslim women also commonly wear burqas and hijabs in public. In addition to the traditional Indian and Muslim garments, increasing exposure to western cultures has led to a rise in the wearing of western style clothing among youths.

 

LITERATURE

In the past, Qutb Shahi rulers and Nizams attracted artists, architects and men of letters from different parts of the world through patronage. The resulting ethnic mix popularised cultural events such as mushairas (poetic symposia). The Qutb Shahi dynasty particularly encouraged the growth of Deccani Urdu literature leading to works such as the Deccani Masnavi and Diwan poetry, which are among the earliest available manuscripts in Urdu. Lazzat Un Nisa, a book compiled in the 15th century at Qutb Shahi courts, contains erotic paintings with diagrams for secret medicines and stimulants in the eastern form of ancient sexual arts. The reign of the Nizams saw many literary reforms and the introduction of Urdu as a language of court, administration and education. In 1824, a collection of Urdu Ghazal poetry, named Gulzar-e-Mahlaqa, authored by Mah Laqa Bai - the first female Urdu poet to produce a Diwan - was published in Hyderabad.

 

Hyderabad has continued with these traditions in its annual Hyderabad Literary Festival, held since 2010, showcasing the city's literary and cultural creativity. Organisations engaged in the advancement of literature include the Sahitya Akademi, the Urdu Academy, the Telugu Academy, the National Council for Promotion of Urdu Language, the Comparative Literature Association of India, and the Andhra Saraswata Parishad. Literary development is further aided by state institutions such as the State Central Library, the largest public library in the state which was established in 1891, and other major libraries including the Sri Krishna Devaraya Andhra Bhasha Nilayam, the British Library and the Sundarayya Vignana Kendram.

 

MUSIC AND FILMS

South Indian music and dances such as the Kuchipudi and Kathakali styles are popular in the Deccan region. As a result of their culture policies, North Indian music and dance gained popularity during the rule of the Mughals and Nizams, and it was also during their reign that it became a tradition among the nobility to associate themselves with tawaif (courtesans). These courtesans were revered as the epitome of etiquette and culture, and were appointed to teach singing, poetry and classical dance to many children of the aristocracy. This gave rise to certain styles of court music, dance and poetry. Besides western and Indian popular music genres such as filmi music, the residents of Hyderabad play city-based marfa music, dholak ke geet (household songs based on local Folklore), and qawwali, especially at weddings, festivals and other celebratory events. The state government organises the Golconda Music and Dance Festival, the Taramati Music Festival and the Premavathi Dance Festival to further encourage the development of music.

 

Although the city is not particularly noted for theatre and drama, the state government promotes theatre with multiple programmes and festivals in such venues as the Ravindra Bharati, Shilpakala Vedika and Lalithakala Thoranam. Although not a purely music oriented event, Numaish, a popular annual exhibition of local and national consumer products, does feature some musical performances. The city is home to the Telugu film industry, popularly known as Tollywood and as of 2012, produces the second largest number of films in India with the largest number being produced by Bollywood. Films in the local Hyderabadi dialect are also produced and have been gaining popularity since 2005. The city has also hosted international film festivals such as the International Children's Film Festival and the Hyderabad International Film Festival. In 2005, Guinness World Records declared Ramoji Film City to be the world's largest film studio.

 

ART AND HANDICRAFTS

The region is well known for its Golconda and Hyderabad painting styles which are branches of Deccani painting. Developed during the 16th century, the Golconda style is a native style blending foreign techniques and bears some similarity to the Vijayanagara paintings of neighbouring Mysore. A significant use of luminous gold and white colours is generally found in the Golconda style. The Hyderabad style originated in the 17th century under the Nizams. Highly influenced by Mughal painting, this style makes use of bright colours and mostly depicts regional landscape, culture, costumes and jewellery.

 

Although not a centre for handicrafts itself, the patronage of the arts by the Mughals and Nizams attracted artisans from the region to Hyderabad. Such crafts include: Bidriware, a metalwork handicraft from neighbouring Karnataka, which was popularised during the 18th century and has since been granted a Geographical Indication (GI) tag under the auspices of the WTO act; and Zari and Zardozi, embroidery works on textile that involve making elaborate designs using gold, silver and other metal threads. Another example of a handicraft drawn to Hyderabad is Kalamkari, a hand-painted or block-printed cotton textile that comes from cities in Andhra Pradesh. This craft is distinguished in having both a Hindu style, known as Srikalahasti and entirely done by hand, and an Islamic style, known as Machilipatnam that uses both hand and block techniques. Examples of Hyderabad's arts and crafts are housed in various museums including the Salar Jung Museum (housing "one of the largest one-man-collections in the world"), the AP State Archaeology Museum, the Nizam Museum, the City Museum and the Birla Science Museum.

 

CUISINE

Hyderabadi cuisine comprises a broad repertoire of rice, wheat and meat dishes and the skilled use of various spices. Hyderabadi biryani and Hyderabadi haleem, with their blend of Mughlai and Arab cuisines, have become iconic dishes of India. Hyderabadi cuisine is highly influenced by Mughlai and to some extent by French, Arabic, Turkish, Iranian and native Telugu and Marathwada cuisines. Other popular native dishes include nihari, chakna, baghara baingan and the desserts qubani ka meetha, double ka meetha and kaddu ki kheer (a sweet porridge made with sweet gourd).

 

MEDIA

One of Hyderabad's earliest newspapers, The Deccan Times, was established in the 1780s. In modern times, the major Telugu dailies published in Hyderabad are Eenadu, Andhra Jyothy, Sakshi and Namaste Telangana, while the major English papers are The Times of India, The Hindu and The Deccan Chronicle, and the major Urdu papers include The Siasat Daily, The Munsif Daily and Etemaad. Many coffee table magazines, professional magazines and research journals are also regularly published. The Secunderabad Cantonment Board established the first radio station in Hyderabad State around 1919. Deccan Radio was the first radio public broadcast station in the city starting on 3 February 1935, with FM broadcasting beginning in 2000. The available channels in Hyderabad include All India Radio, Radio Mirchi, Radio City, Red FM and Big FM.

 

Television broadcasting in Hyderabad began in 1974 with the launch of Doordarshan, the Government of India's public service broadcaster, which transmits two free-to-air terrestrial television channels and one satellite channel. Private satellite channels started in July 1992 with the launch of Star TV. Satellite TV channels are accessible via cable subscription, direct-broadcast satellite services or internet-based television. Hyderabad's first dial-up internet access became available in the early 1990s and was limited to software development companies. The first public internet access service began in 1995, with the first private sector internet service provider (ISP) starting operations in 1998. In 2015, high-speed public WiFi was introduced in parts of the city.

 

EDUCATION

Public and private schools in Hyderabad are governed by the Central Board of Secondary Education and follow a "10+2+3" plan. About two-thirds of pupils attend privately run institutions. Languages of instruction include English, Hindi, Telugu and Urdu. Depending on the institution, students are required to sit the Secondary School Certificate or the Indian Certificate of Secondary Education. After completing secondary education, students enroll in schools or junior colleges with a higher secondary facility. Admission to professional graduation colleges in Hyderabad, many of which are affiliated with either Jawaharlal Nehru Technological University Hyderabad (JNTUH) or Osmania University (OU), is through the Engineering Agricultural and Medical Common Entrance Test (EAM-CET).There are 13 universities in Hyderabad: two private universities, two deemed universities, six state universities and three central universities. The central universities are the University of Hyderabad, Maulana Azad National Urdu University and the English and Foreign Languages University. Osmania University, established in 1918, was the first university in Hyderabad and as of 2012 is India's second most popular institution for international students. The Dr. B. R. Ambedkar Open University, established in 1982, is the first distance learning open university in India.

 

Hyderabad is also home to a number of centres specialising in particular fields such as biomedical sciences, biotechnology and pharmaceuticals, such as the National Institute of Pharmaceutical Education and Research (NIPER) and National Institute of Nutrition (NIN). Hyderabad has five major medical schools - Osmania Medical College, Gandhi Medical College, Nizam's Institute of Medical Sciences, Deccan College of Medical Sciences and Shadan Institute of Medical Sciences - and many affiliated teaching hospitals.

The National Institute of Design, Hyderabad (NID-H), will offer undergraduate and postgraduate courses from 2015.

 

SPORTS

The most popular sports played in Hyderabad are cricket and association football. At the professional level, the city has hosted national and international sports events such as the 2002 National Games of India, the 2003 Afro-Asian Games, the 2004 AP Tourism Hyderabad Open women's tennis tournament, the 2007 Military World Games, the 2009 World Badminton Championships and the 2009 IBSF World Snooker Championship.

Hyderabad is also home to the Indian Premier League franchise Sunrisers Hyderabad. A previous franchise was the Deccan Chargers, which won the 2009 Indian Premier League held in South Africa.

 

During British rule, Secunderabad became a well-known sporting centre and many race courses, parade grounds and polo fields were built. Many elite clubs formed by the Nizams and the British such as the Secunderabad Club, the Nizam Club and the Hyderabad Race Club, which is known for its horse racing especially the annual Deccan derby, still exist. In more recent times, motorsports has become popular with the Andhra Pradesh Motor Sports Club organising popular events such as the Deccan 1/4 Mile Drag, TSD Rallies and 4x4 off-road rallying.

TRANSPORT

The most commonly used forms of medium distance transport in Hyderabad include government owned services such as light railways and buses, as well as privately operated taxis and auto rickshaws. Bus services operate from the Mahatma Gandhi Bus Station in the city centre and carry over 130 million passengers daily across the entire network. Hyderabad's light rail transportation system, the Multi-Modal Transport System (MMTS), is a three line suburban rail service used by over 160,000 passengers daily. Complementing these government services are minibus routes operated by Setwin (Society for Employment Promotion & Training in Twin Cities). Intercity rail services also operate from Hyderabad; the main, and largest, station is Secunderabad Railway Station, which serves as Indian Railways' South Central Railway zone headquarters and a hub for both buses and MMTS light rail services connecting Secunderabad and Hyderabad. Other major railway stations in Hyderabad are Hyderabad Deccan Station, Kachiguda Railway Station, Begumpet Railway Station, Malkajgiri Railway Station and Lingampally Railway Station. The Hyderabad Metro, a new rapid transit system, is to be added to the existing public transport infrastructure and is scheduled to operate three lines by 2015. As of 2012, there are over 3.5 million vehicles operating in the city, of which 74% are two-wheelers, 15% cars and 3% three-wheelers. The remaining 8% include buses, goods vehicles and taxis. The large number of vehicles coupled with relatively low road coverage - roads occupy only 9.5% of the total city area - has led to widespread traffic congestion especially since 80% of passengers and 60% of freight are transported by road. The Inner Ring Road, the Outer Ring Road, the Hyderabad Elevated Expressway, the longest flyover in India, and various interchanges, overpasses and underpasses were built to ease the congestion. Maximum speed limits within the city are 50 km/h for two-wheelers and cars, 35 km/h for auto rickshaws and 40 km/h for light commercial vehicles and buses.

 

Hyderabad sits at the junction of three National Highways linking it to six other states: NH-7 runs 2,369 km from Varanasi, Uttar Pradesh, in the north to Kanyakumari, Tamil Nadu, in the south; NH-9, runs 841 km east-west between Machilipatnam, Andhra Pradesh, and Pune, Maharashtra; and the 280 km NH-163 links Hyderabad to Bhopalpatnam, Chhattisgarh. Five state highways, SH-1, SH-2, SH-4, SH-5 and SH-6, either start from, or pass through, Hyderabad.

 

Air traffic was previously handled via Begumpet Airport, but this was replaced by Rajiv Gandhi International Airport (RGIA) (IATA: HYD, ICAO: VOHS) in 2008, with the capacity of handling 12 million passengers and 100,000 tonnes of cargo per annum. In 2011, Airports Council International, an autonomous body representing the world's airports, judged RGIA the world's best airport in the 5–15 million passenger category and the world's fifth best airport for service quality.

 

WIKIPEDIA

Positano, Italy is a popular tourist destination known for its scenic views, beaches, and luxury, but it's also expensive and crowded:

Cost: Positano is the most expensive town on the Amalfi Coast. Shopping and parking can be expensive, and most houses don't have parking.

Endless staircases are still a way of life for the hardy locals. While Positano has 4,000 residents, an average of 12,000 tourists visit daily between Easter and October.

A work in progress, this is a real-time sales dashboard for cincottachemist.com.au

 

The goal is to provide an at-a-glance view on where sales are for the day, trending product and searches and visibility over order queues.

 

Note: I have set numbers to zero or blurred terms for confidentiality reasons.

 

Check out the notes above for information on what we're tracking.

 

I should also give props to Panic. While I have done a few dashboards in my time I definitely took some inspiration from their status screen -- it also motivated me to make some progress on this project.

An average one, has some scratches but Is all complete, I replaced the badge

This is the back of my 2018 Fujifilm X-T3.

Top right, in the red box, you can see that the metering collar dial is set to 'MULTI'.

 

In yellow you can see that the camera is actually in 'AVERAGE', not 'MULTI'. If you touch and jiggle the dial a bit, it jumps in and out of 'MULTI' but it is unreliable.

 

Top left, in blue, is another collar dial which is called the 'DRIVE MODE' dial and that is also jittery. It is now set to S (single) but sometimes it jumps to CL (continuous low) to the left or 'MULTI EXPOSURE' to the right on its own.

 

These are very important but low quality dials. I have a much older Pentax K-5 with collar dials and those are flawless.

 

I think they had a boardroom meeting before the launch of the camera: Kenny: "Okay boss, our X-T3 is almost finished, we just need to select the type of metering- and drive mode dials. What kind of dials do you want? We've got these top-of-the-line Zaratsu polished gold plated Japanese made dials that can withstand 50 billion movement and we've got these plastic ones which are 2 cent a pop and also used by European- and American car manufacturers." Boss: "Well Kenny, put those cheap ones in, if they are good enough for the European- and American car consumers, they are good enough for our cameras. They don't know what quality is and they don't expect for it to last for more than 3 years anyway."

 

I like these "X-T" line of camera's but my "X-H" doesn't have these bullshit collar dials and proved to be more reliable. I'm not a Fujifilm fanboy, I'm a Pentax refugee.

The average rainfall for Palm Valley is only 200 mm per year. Although the gorge usually appears dry, there are some small pockets of semi-permanent spring-fed pools that allow the unique flora in this region to survive. During significant rainfall in the region, an expanses of water can be witnessed flowing through the valley gorge. During such events, a variety of aquatic life such as desert fish, shield shrimps (Triops australiensis), tadpoles and frogs can flourish

There was a regular hatch of big dark Olives today on that corrie loch (see the next picture). This "average" fish took a green Olive size 14. The fog was so thick that you sometimes couldn't see your fly. But as there was no wind you could hear the fish rising. Tricky but exciting.

 

Safely released like all the fogs of this gallery.

 

Note about this gallery : if the name of the lochs are fake, in order to preserve them from the angling pressure, the areas are always accurate.

When there is one color you can attribute to a city it is grey. By no means this is a bad thing. There are just so many things from art to imagination and stone to the people living inside that all that really matters is the contrast of all the life and impressions.

The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them.

 

The various geyser basins are located where rainwater and snowmelt can percolate into the ground, get indirectly superheated by the underlying Yellowstone hotspot, and then erupt at the surface as geysers, hot springs, and fumaroles. Thus flat-bottomed valleys between ancient lava flows and glacial moraines are where most of the large geothermal areas are located. Smaller geothermal areas can be found where fault lines reach the surface, in places along the circular fracture zone around the caldera, and at the base of slopes that collect excess groundwater. Due to the Yellowstone Plateau's high elevation the average boiling temperature at Yellowstone's geyser basins is 199 °F (93 °C). When properly confined and close to the surface it can periodically release some of the built-up pressure in eruptions of hot water and steam that can reach up to 390 feet (120 m) into the air (see Steamboat Geyser, the world's tallest geyser). Water erupting from Yellowstone's geysers is superheated above that boiling point to an average of 204 °F (95.5 °C) as it leaves the vent. The water cools significantly while airborne and is no longer scalding hot by the time it strikes the ground, nearby boardwalks, or even spectators. Because of the high temperatures of the water in the features it is important that spectators remain on the boardwalks and designated trails. Several deaths have occurred in the park as a result of falls into hot springs.

 

Prehistoric Native American artifacts have been found at Mammoth Hot Springs and other geothermal areas in Yellowstone. Some accounts state that the early people used hot water from the geothermal features for bathing and cooking. In the 19th century Father Pierre-Jean De Smet reported that natives he interviewed thought that geyser eruptions were "the result of combat between the infernal spirits". The Lewis and Clark Expedition traveled north of the Yellowstone area in 1806. Local natives that they came upon seldom dared to enter what we now know is the caldera because of frequent loud noises that sounded like thunder and the belief that the spirits that possessed the area did not like human intrusion into their realm. The first white man known to travel into the caldera and see the geothermal features was John Colter, who had left the Lewis and Clark Expedition. He described what he saw as "hot spring brimstone". Beaver trapper Joseph Meek recounted in 1830 that the steam rising from the various geyser basins reminded him of smoke coming from industrial smokestacks on a cold winter morning in Pittsburgh, Pennsylvania. In the 1850s famed trapper Jim Bridger called it "the place where Hell bubbled up".

 

The heat that drives geothermal activity in the Yellowstone area comes from brine (salty water) that is 1.5–3 miles (7,900–15,800 ft; 2,400–4,800 m) below the surface. This is actually below the solid volcanic rock and sediment that extends to a depth of 3,000 to 6,000 feet (900 to 1,800 m) and is inside the hot but mostly solid part of the pluton that contains Yellowstone's magma chamber. At that depth the brine is superheated to temperatures that exceed 400 °F (204 °C) but is able to remain a liquid because it is under great pressure (like a huge pressure cooker).

 

Convection of the churning brine and conduction from surrounding rock transfers heat to an overlaying layer of fresh groundwater. Movement of the two liquids is facilitated by the highly fractured and porous nature of the rocks under the Yellowstone Plateau. Some silica is dissolved from the fractured rhyolite into the hot water as it travels through the fractured rock. Part of this hard mineral is later redeposited on the walls of the cracks and fissures to make a nearly pressure-tight system. Silica precipitates at the surface to form either geyserite or sinter, creating the massive geyser cones, the scalloped edges of hot springs, and the seemingly barren landscape of geyser basins.

 

There are at least five types of geothermal features found at Yellowstone:

 

Fumaroles: Fumaroles, or steam vents, are the hottest hydrothermal features in the park. They have so little water that it all flashes into steam before reaching the surface. At places like Roaring Mountain, the result is loud hissing of steam and gases.

Geysers: Geysers such as Old Faithful are a type of geothermal feature that periodically erupt scalding hot water. Increased pressure exerted by the enormous weight of the overlying rock and water prevents deeper water from boiling. As the hot water rises it is under less pressure and steam bubbles form. They, in turn, expand on their ascent until the bubbles are too big and numerous to pass freely through constrictions. At a critical point the confined bubbles actually lift the water above, causing the geyser to splash or overflow. This decreases the pressure of the system and violent boiling results. Large quantities of water flash into tremendous amounts of steam that force a jet of water out of the vent: an eruption begins. Water (and heat) is expelled faster than the geyser's recharge rate, gradually decreasing the system's pressure and eventually ending the eruption.

Hot springs: Hot springs such as Grand Prismatic Spring are the most common hydrothermal features in the park. Their plumbing has no constrictions. Superheated water cools as it reaches the surface, sinks, and is replaced by hotter water from below. This circulation, called convection, prevents water from reaching the temperature needed to set off an eruption. Many hot springs give rise to streams of heated water.

Mudpots: Mudpots such as Fountain Paint Pots are acidic hot springs with a limited water supply. Some microorganisms use hydrogen sulfide (rotten egg smell), which rises from deep within the earth, as an energy source. They convert the gas into sulfuric acid, which breaks down rock into clay.

Travertine terraces: Travertine terraces, found at Mammoth Hot Springs, are formed from limestone (a rock type made of calcium carbonate). Thermal waters rise through the limestone, carrying high amounts of dissolved carbonate. Carbon dioxide is released at the surface and calcium carbonate deposited as travertine, the chalky white rock of the terraces. These features constantly and quickly change due to the rapid rate of deposition.

Geyser basins

 

The Norris Geyser Basin 44°43′43″N 110°42′16″W is the hottest geyser basin in the park and is located near the northwest edge of Yellowstone Caldera near Norris Junction and on the intersection of three major faults. The Norris-Mammoth Corridor is a fault that runs from Norris north through Mammoth to the Gardiner, Montana, area. The Hebgen Lake fault runs from northwest of West Yellowstone, Montana, to Norris. This fault experienced an earthquake in 1959 that measured 7.4 on the Richter scale (sources vary on exact magnitude between 7.1 and 7.8; see 1959 Hebgen Lake earthquake). Norris Geyser Basin is so hot and dynamic because these two faults intersect with the ring fracture zone that resulted from the creation of the Yellowstone Caldera of 640,000 years ago.

 

The Basin consists of three main areas: Porcelain Basin, Back Basin, and One Hundred Springs Plain. Unlike most of other geyser basins in the park, the waters from Norris are acidic rather than alkaline (for example, Echinus Geyser has a pH of ~3.5). The difference in pH allows for a different class of bacterial thermophiles to live at Norris, creating different color patterns in and around the Norris Basin waters.

 

The Ragged Hills that lie between Back Basin and One Hundred Springs Plain are thermally altered glacial kames. As glaciers receded the underlying thermal features began to express themselves once again, melting remnants of the ice and causing masses of debris to be dumped. These debris piles were then altered by steam and hot water flowing through them. Madison lies within the eroded stream channels cut through lava flows formed after the caldera eruption. The Gibbon Falls lies on the caldera boundary as does Virginia Cascades.

The tallest active geyser in the world, Steamboat Geyser,[11] is located in Norris Basin. Unlike the slightly smaller but much more famous Old Faithful Geyser located in Upper Geyser Basin, Steamboat has an erratic and lengthy timetable between major eruptions. During major eruptions, which may be separated by intervals of more than a year (the longest recorded span between major eruptions was 50 years), Steamboat erupts over 300 feet (90 m) into the air. Steamboat does not lie dormant between eruptions, instead displaying minor eruptions of approximately 40 feet (12 m).

 

Norris Geyser Basin periodically undergoes a large-scale, basin-wide thermal disturbance lasting a few weeks. Water levels fluctuate, and temperatures, pH, colors, and eruptive patterns change throughout the basin. During a disturbance in 1985, Porkchop Geyser continually jetted steam and water; in 1989, the same geyser apparently clogged with silica and blew up, throwing rocks more than 200 feet (61 m). In 2003 a park ranger observed it bubbling heavily, the first such activity seen since 1991. Activity increased dramatically in mid-2003. Because of high ground temperatures and new features beside the trail much of Back Basin was closed until October. In 2004 the boardwalk was routed around the dangerous area and now leads behind Porkchop Geyser.

 

North of Norris, Roaring Mountain is a large, acidic hydrothermal area (solfatara) with many fumaroles. In the late 19th and early 20th centuries, the number, size, and power of the fumaroles were much greater than today. The fumaroles are most easily seen in the cooler, low-light conditions of morning and evening.

 

The Gibbon Geyser Basin 44°41′58″N 110°44′34″W includes several thermal areas in the vicinity of the Gibbon River between Gibbon Falls and Norris. The most accessible feature in the basin is Beryl Spring, with a small boardwalk right along the Grand Loop Road. Artists' Paintpots is a small hydrothermal area south of Norris Junction that includes colorful hot springs and two large mudpots.

 

The Monument Geyser Basin 44°41′03″N 110°45′14″W has no active geysers, but its 'monuments' are siliceous sinter deposits similar to the siliceous spires discovered on the floor of Yellowstone Lake. Scientists hypothesize that this basin's structures formed from a hot water system in a glacially dammed lake during the waning stages of the Pinedale Glaciation. The basin is on a ridge reached by a very steep one-mile (1.6 km) trail south of Artists' Paint Pots. Other areas of thermal activity in Gibbon Geyser Basin lie off-trail.

 

South of Norris along the rim of the caldera is the Upper Geyser Basin 44°27′52″N 110°49′45″W, which has the highest concentration of geothermal features in the park. This complement of features includes the most famous geyser in the park, Old Faithful Geyser, as well as four other predictable large geysers. One of these large geysers in the area is Castle Geyser which is about 1,400 feet (430 m) northwest of Old Faithful. Castle Geyser has an interval of approximately 13 hours between major eruptions, but is unpredictable after minor eruptions. The other three predictable geysers are Grand Geyser, Daisy Geyser, and Riverside Geyser. Biscuit Basin and Black Sand Basin are also within the boundaries of Upper Geyser Basin.

 

The hills surrounding Old Faithful and the Upper Geyser Basin are reminders of Quaternary rhyolitic lava flows. These flows, occurring long after the catastrophic eruption of 640,000 years ago, flowed across the landscape like stiff mounds of bread dough due to their high silica content.

 

Evidence of glacial activity is common, and it is one of the keys that allows geysers to exist. Glacier till deposits underlie the geyser basins providing storage areas for the water used in eruptions. Many landforms, such as Porcupine Hills north of Fountain Flats, are made up of glacial gravel and are reminders that 70,000 to 14,000 years ago, this area was buried under ice.

 

Signs of the forces of erosion can be seen everywhere, from runoff channels carved across the sinter in the geyser basins to the drainage created by the Firehole River. Mountain building is evident on the drive south of Old Faithful, toward Craig Pass. Here the Rocky Mountains reach a height of 8,262 feet (2,518 m), dividing the country into two distinct watersheds.

 

Midway Geyser Basin 44°31′04″N 110°49′56″W is much smaller than the other basins found alongside the Firehole River. Despite its small size, it contains two large features, the 200-by-300-foot-wide (60 by 90 m) Excelsior Geyser which pours over 4,000 U.S. gallons (15,000 L; 3,300 imp gal) per minute into the Firehole River. The largest hot spring in Yellowstone, the 370-foot-wide (110 m) and 121-foot-deep (37 m) Grand Prismatic Spring is found here. Also in the basin is Turquoise Pool and Opal Pool.

 

Lower Geyser Basin

Silex Spring at Fountain Paint Pot

 

Farther north is the Lower Geyser Basin 44°32′58″N 110°50′09″W, which is the largest geyser basin in area, covering approximately 11 square miles. Due to its large size, it has a much less concentrated set of geothermal features, including Fountain Paint Pots. Fountain Paint Pots are mud pots, that is, a hot spring that contains boiling mud instead of water. The mud is produced by a higher acidity in the water which enables the spring to dissolve surrounding minerals to create an opaque, usually grey, mud. Also there is Firehole Spring, Celestine Pool, Leather Pool, Red Spouter, Jelly spring, and a number of fumaroles.

 

Geysers in Lower Geyser Basin include Great Fountain Geyser, whose eruptions reach 100 to 200 feet (30–61 m) in the air, while waves of water cascade down its sinter terraces., the Fountain group of Geysers (Clepsydra Geyser which erupts nearly continuously to heights of 45 feet (14 m), Fountain Geyser, Jelly Geyser, Jet Geyser, Morning Geyser, and Spasm Geyser), the Pink Cone group of geysers (Dilemma Geyser, Labial Geyser, Narcissus Geyser, Pink Geyser, and Pink Cone Geyser), the White Dome group of geysers (Crack Geyser, Gemini Geyser, Pebble Geyser, Rejuvenated Geyser, and White Dome Geyser), as well as Sizzler Geyser.

Overflow areas of Silex springs

 

The West Thumb Geyser Basin 44°25′07″N 110°34′23″W, including Potts Basin to the north, is the largest geyser basin on the shores of Yellowstone Lake. The heat source of the thermal features in this location is thought to be relatively close to the surface, only 10,000 feet (3,000 m) down. West Thumb is about the same size as another famous volcanic caldera, Crater Lake in Oregon, but much smaller than the great Yellowstone Caldera which last erupted about 640,000 years ago. West Thumb is a caldera within a caldera.

 

West Thumb was created approximately 162,000 years ago when a magma chamber bulged up under the surface of the earth and subsequently cracked it along ring fracture zones. This in turn released the enclosed magma as lava and caused the surface above the emptied magma chamber to collapse. Water later filled the collapsed area of the caldera, forming an extension of Yellowstone Lake. This created the source of heat and water that feed the West Thumb Geyser Basin today.

 

The thermal features at West Thumb are not only found on the lake shore, but extend under the surface of the lake as well. Several underwater hydrothermal features were discovered in the early 1990s and can be seen as slick spots or slight bulges in the summer. During the winter, the underwater thermal features are visible as melt holes in the icy surface of the lake. The surrounding ice can reach three feet (one yard) in thickness.

 

Perhaps the most famous hydrothermal feature at West Thumb is a geyser on the lake shore known as Fishing Cone. Walter Trumbull of the 1870 Washburn-Langford-Doane Expedition described a unique event while a man was fishing adjacent to the cone: "...in swinging a trout ashore, it accidentally got off the hook and fell into the spring. For a moment it darted about with wonderful rapidity, as if seeking an outlet. Then it came to the top, dead, and literally boiled." Fishing Cone erupted frequently to the height of 40 feet (12 m) in 1919 and to lesser heights in 1939. One fisherman was badly burned in Fishing Cone in 1921. Fishing at the geyser is now prohibited.

 

Early visitors would arrive at West Thumb via stagecoach from the Old Faithful area. They had a choice of continuing on the stagecoach or boarding the steamship Zillah to continue the journey by water to Lake Hotel. The boat dock was located near the south end of the geyser basin near Lakeside Spring.

 

Backcountry Geyser Basins

The Heart Lake 44°18′00″N 110°30′56″W, Lone Star 44°24′50″N 110°49′04″W, and Shoshone Geyser Basins 44°21′16″N 110°47′57″W are located away from the road and require at least several miles of hiking to reach. These areas lack the boardwalks and other safety features of the developed areas. As falling into geothermal features can be fatal, it is usually advisable to visit these areas with an experienced guide or at the very least, travelers need to ensure they remain on well-marked trails.

 

The Heart Lake Geyser Basin contains several groups of geysers and deep blue hot springs near Heart Lake in the south-central portion of Yellowstone, southeast of most of the main geyser basins. Lying in the Snake River watershed east of Lewis Lake and south of Yellowstone Lake, Heart Lake was named sometime before 1871 for Hart Hunney, a hunter. Other explorers in the region incorrectly assumed that the lake's name was spelled 'heart' because of its shape. The Heart Lake Geyser Basin begins a couple miles from the lake and descends along Witch Creek to the lakeshore. Five groups of hydrothermal features comprise the basin, and all of them contain geysers, although some are dormant.

 

Between Shoshone Lake and Old Faithful is the Lone Star Geyser Basin, of which the primary feature is Lone Star Geyser, named for its isolation from the nearby geysers of the Upper Geyser Basin. The basin is reachable on foot or bicycle via a 3 mile road that is closed to vehicles.

 

The Shoshone Geyser Basin, reached by hiking or by boat, contains one of the highest concentrations of geysers in the world – more than 80 in an area 1,600 by 800 feet (490 by 240 m). Hot springs and mudpots dot the landscape between the geyser basin and Shoshone Lake.

 

Hot Spring Basin is located 15 miles (24 km) north-northeast of Fishing Bridge and has one of Yellowstone's largest collections of hot springs and fumaroles. The geothermal features there release large amounts of sulfur. This makes water from the springs so acidic that it has dissolved holes in the pants of people who sit on wet ground and causes mounds of sulfur three feet (1 m) high to develop around fumaroles. The very hot acidic water and steam have also created voids in the ground that are only covered by a thin crust.

 

Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Because of the huge amount of geothermal vents, travertine flourishes. Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas.

 

The thermal features at Mud Volcano and Sulphur Caldron are primarily mud pots and fumaroles because the area is situated on a perched water system with little water available. Fumaroles or "steam vents" occur when the ground water boils away faster than it can be recharged. Also, the vapors are rich in sulfuric acid that leaches the rock, breaking it down into clay. Because no water washes away the acid or leached rock, it remains as sticky clay to form a mud pot. Hydrogen sulfide gas is present deep in the earth at Mud Volcano and is oxidized to sulfuric acid by microbial activity, which dissolves the surface soils to create pools and cones of clay and mud. Along with hydrogen sulfide, steam, carbon dioxide, and other gases explode through the layers of mud.

 

A series of shallow earthquakes associated with the volcanic activity in Yellowstone struck this area in 1978. Soil temperatures increased to nearly 200 °F (93 °C). The slope between Sizzling Basin and Mud Geyser, once covered with green grass and trees, became a barren landscape of fallen trees known as "the cooking hillside".

 

Yellowstone National Park is a national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the 42nd U.S. Congress with the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

 

While Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the U.S. Department of the Interior, the first Secretary of the Interior to supervise the park being Columbus Delano. However, the U.S. Army was eventually commissioned to oversee the management of Yellowstone for 30 years between 1886 and 1916. In 1917, the administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.

 

Yellowstone National Park spans an area of 3,468.4 sq mi (8,983 km2), comprising lakes, canyons, rivers, and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest super volcano on the continent. The caldera is considered a dormant volcano. It has erupted with tremendous force several times in the last two million years. Well over half of the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.

 

Hundreds of species of mammals, birds, fish, reptiles, and amphibians have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the contiguous United States. Grizzly bears, cougars, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one-third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing, and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.

 

Teton County is a county in the U.S. state of Wyoming. As of the 2020 United States Census, the population was 23,331. Its county seat is Jackson. Its west boundary line is also the Wyoming state boundary shared with Idaho and the southern tip of Montana. Teton County is part of the Jackson, WY-ID Micropolitan Statistical Area.

 

Teton County contains the Jackson Hole ski area, all of Grand Teton National Park, and 40.4% of Yellowstone National Park's total area, including over 96.6% of its water area (largely in Yellowstone Lake).

 

Wyoming is a state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With a population of 576,851 in 2020, Wyoming is the least populous state despite being the 10th largest by area, with the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had an estimated population of 63,957 in 2018.

 

Wyoming's western half consists mostly of the ranges and rangelands of the Rocky Mountains; its eastern half consists of high-elevation prairie, and is referred to as the High Plains. Wyoming's climate is semi-arid in some parts and continental in others, making it drier and windier overall than other states, with greater temperature extremes. The federal government owns just under half of Wyoming's land, generally protecting it for public uses. The state ranks sixth in the amount of land—-and fifth in the proportion of its land—-that is owned by the federal government. Its federal lands include two national parks (Grand Teton and Yellowstone), two national recreation areas, two national monuments, and several national forests, as well as historic sites, fish hatcheries, and wildlife refuges.

 

Indigenous peoples inhabited the region for thousands of years. Historic and currently federally recognized tribes include the Arapaho, Crow, Lakota, and Shoshone. Part of the land that is now Wyoming came under American sovereignty via the Louisiana Purchase, part via the Oregon Treaty, and, lastly, via the Mexican Cession. With the opening of the Oregon Trail, the Mormon Trail, and the California Trail, vast numbers of pioneers travelled through parts of the state that had once been traversed mainly by fur trappers, and this spurred the establishment of forts, such as Fort Laramie, that today serve as population centers. The Transcontinental Railroad supplanted the wagon trails in 1867 with a route through southern Wyoming, bringing new settlers and the establishment of founding towns, including the state capital of Cheyenne. On March 27, 1890, Wyoming became the union's 44th state.

 

Farming and ranching, and the attendant range wars, feature prominently in the state's history. Today, Wyoming's economy is largely based on tourism and the extraction of minerals such as coal, natural gas, oil, and trona. Its agricultural commodities include barley, hay, livestock, sugar beets, wheat, and wool.

 

Wyoming was the first state to allow women the right to vote (not counting New Jersey, which had allowed it until 1807), and the right to assume elected office, as well as the first state to elect a female governor. In honor of this part of its history, its most common nickname is "The Equality State" and its official state motto is "Equal Rights". It is among the least religious states in the country, and is known for having a political culture that leans towards libertarian conservatism. The Republican presidential nominee has carried the state in every election since 1968.

The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them.

 

The various geyser basins are located where rainwater and snowmelt can percolate into the ground, get indirectly superheated by the underlying Yellowstone hotspot, and then erupt at the surface as geysers, hot springs, and fumaroles. Thus flat-bottomed valleys between ancient lava flows and glacial moraines are where most of the large geothermal areas are located. Smaller geothermal areas can be found where fault lines reach the surface, in places along the circular fracture zone around the caldera, and at the base of slopes that collect excess groundwater. Due to the Yellowstone Plateau's high elevation the average boiling temperature at Yellowstone's geyser basins is 199 °F (93 °C). When properly confined and close to the surface it can periodically release some of the built-up pressure in eruptions of hot water and steam that can reach up to 390 feet (120 m) into the air (see Steamboat Geyser, the world's tallest geyser). Water erupting from Yellowstone's geysers is superheated above that boiling point to an average of 204 °F (95.5 °C) as it leaves the vent. The water cools significantly while airborne and is no longer scalding hot by the time it strikes the ground, nearby boardwalks, or even spectators. Because of the high temperatures of the water in the features it is important that spectators remain on the boardwalks and designated trails. Several deaths have occurred in the park as a result of falls into hot springs.

 

Prehistoric Native American artifacts have been found at Mammoth Hot Springs and other geothermal areas in Yellowstone. Some accounts state that the early people used hot water from the geothermal features for bathing and cooking. In the 19th century Father Pierre-Jean De Smet reported that natives he interviewed thought that geyser eruptions were "the result of combat between the infernal spirits". The Lewis and Clark Expedition traveled north of the Yellowstone area in 1806. Local natives that they came upon seldom dared to enter what we now know is the caldera because of frequent loud noises that sounded like thunder and the belief that the spirits that possessed the area did not like human intrusion into their realm. The first white man known to travel into the caldera and see the geothermal features was John Colter, who had left the Lewis and Clark Expedition. He described what he saw as "hot spring brimstone". Beaver trapper Joseph Meek recounted in 1830 that the steam rising from the various geyser basins reminded him of smoke coming from industrial smokestacks on a cold winter morning in Pittsburgh, Pennsylvania. In the 1850s famed trapper Jim Bridger called it "the place where Hell bubbled up".

 

The heat that drives geothermal activity in the Yellowstone area comes from brine (salty water) that is 1.5–3 miles (7,900–15,800 ft; 2,400–4,800 m) below the surface. This is actually below the solid volcanic rock and sediment that extends to a depth of 3,000 to 6,000 feet (900 to 1,800 m) and is inside the hot but mostly solid part of the pluton that contains Yellowstone's magma chamber. At that depth the brine is superheated to temperatures that exceed 400 °F (204 °C) but is able to remain a liquid because it is under great pressure (like a huge pressure cooker).

 

Convection of the churning brine and conduction from surrounding rock transfers heat to an overlaying layer of fresh groundwater. Movement of the two liquids is facilitated by the highly fractured and porous nature of the rocks under the Yellowstone Plateau. Some silica is dissolved from the fractured rhyolite into the hot water as it travels through the fractured rock. Part of this hard mineral is later redeposited on the walls of the cracks and fissures to make a nearly pressure-tight system. Silica precipitates at the surface to form either geyserite or sinter, creating the massive geyser cones, the scalloped edges of hot springs, and the seemingly barren landscape of geyser basins.

 

There are at least five types of geothermal features found at Yellowstone:

 

Fumaroles: Fumaroles, or steam vents, are the hottest hydrothermal features in the park. They have so little water that it all flashes into steam before reaching the surface. At places like Roaring Mountain, the result is loud hissing of steam and gases.

Geysers: Geysers such as Old Faithful are a type of geothermal feature that periodically erupt scalding hot water. Increased pressure exerted by the enormous weight of the overlying rock and water prevents deeper water from boiling. As the hot water rises it is under less pressure and steam bubbles form. They, in turn, expand on their ascent until the bubbles are too big and numerous to pass freely through constrictions. At a critical point the confined bubbles actually lift the water above, causing the geyser to splash or overflow. This decreases the pressure of the system and violent boiling results. Large quantities of water flash into tremendous amounts of steam that force a jet of water out of the vent: an eruption begins. Water (and heat) is expelled faster than the geyser's recharge rate, gradually decreasing the system's pressure and eventually ending the eruption.

Hot springs: Hot springs such as Grand Prismatic Spring are the most common hydrothermal features in the park. Their plumbing has no constrictions. Superheated water cools as it reaches the surface, sinks, and is replaced by hotter water from below. This circulation, called convection, prevents water from reaching the temperature needed to set off an eruption. Many hot springs give rise to streams of heated water.

Mudpots: Mudpots such as Fountain Paint Pots are acidic hot springs with a limited water supply. Some microorganisms use hydrogen sulfide (rotten egg smell), which rises from deep within the earth, as an energy source. They convert the gas into sulfuric acid, which breaks down rock into clay.

Travertine terraces: Travertine terraces, found at Mammoth Hot Springs, are formed from limestone (a rock type made of calcium carbonate). Thermal waters rise through the limestone, carrying high amounts of dissolved carbonate. Carbon dioxide is released at the surface and calcium carbonate deposited as travertine, the chalky white rock of the terraces. These features constantly and quickly change due to the rapid rate of deposition.

Geyser basins

 

The Norris Geyser Basin 44°43′43″N 110°42′16″W is the hottest geyser basin in the park and is located near the northwest edge of Yellowstone Caldera near Norris Junction and on the intersection of three major faults. The Norris-Mammoth Corridor is a fault that runs from Norris north through Mammoth to the Gardiner, Montana, area. The Hebgen Lake fault runs from northwest of West Yellowstone, Montana, to Norris. This fault experienced an earthquake in 1959 that measured 7.4 on the Richter scale (sources vary on exact magnitude between 7.1 and 7.8; see 1959 Hebgen Lake earthquake). Norris Geyser Basin is so hot and dynamic because these two faults intersect with the ring fracture zone that resulted from the creation of the Yellowstone Caldera of 640,000 years ago.

 

The Basin consists of three main areas: Porcelain Basin, Back Basin, and One Hundred Springs Plain. Unlike most of other geyser basins in the park, the waters from Norris are acidic rather than alkaline (for example, Echinus Geyser has a pH of ~3.5). The difference in pH allows for a different class of bacterial thermophiles to live at Norris, creating different color patterns in and around the Norris Basin waters.

 

The Ragged Hills that lie between Back Basin and One Hundred Springs Plain are thermally altered glacial kames. As glaciers receded the underlying thermal features began to express themselves once again, melting remnants of the ice and causing masses of debris to be dumped. These debris piles were then altered by steam and hot water flowing through them. Madison lies within the eroded stream channels cut through lava flows formed after the caldera eruption. The Gibbon Falls lies on the caldera boundary as does Virginia Cascades.

The tallest active geyser in the world, Steamboat Geyser,[11] is located in Norris Basin. Unlike the slightly smaller but much more famous Old Faithful Geyser located in Upper Geyser Basin, Steamboat has an erratic and lengthy timetable between major eruptions. During major eruptions, which may be separated by intervals of more than a year (the longest recorded span between major eruptions was 50 years), Steamboat erupts over 300 feet (90 m) into the air. Steamboat does not lie dormant between eruptions, instead displaying minor eruptions of approximately 40 feet (12 m).

 

Norris Geyser Basin periodically undergoes a large-scale, basin-wide thermal disturbance lasting a few weeks. Water levels fluctuate, and temperatures, pH, colors, and eruptive patterns change throughout the basin. During a disturbance in 1985, Porkchop Geyser continually jetted steam and water; in 1989, the same geyser apparently clogged with silica and blew up, throwing rocks more than 200 feet (61 m). In 2003 a park ranger observed it bubbling heavily, the first such activity seen since 1991. Activity increased dramatically in mid-2003. Because of high ground temperatures and new features beside the trail much of Back Basin was closed until October. In 2004 the boardwalk was routed around the dangerous area and now leads behind Porkchop Geyser.

 

North of Norris, Roaring Mountain is a large, acidic hydrothermal area (solfatara) with many fumaroles. In the late 19th and early 20th centuries, the number, size, and power of the fumaroles were much greater than today. The fumaroles are most easily seen in the cooler, low-light conditions of morning and evening.

 

The Gibbon Geyser Basin 44°41′58″N 110°44′34″W includes several thermal areas in the vicinity of the Gibbon River between Gibbon Falls and Norris. The most accessible feature in the basin is Beryl Spring, with a small boardwalk right along the Grand Loop Road. Artists' Paintpots is a small hydrothermal area south of Norris Junction that includes colorful hot springs and two large mudpots.

 

The Monument Geyser Basin 44°41′03″N 110°45′14″W has no active geysers, but its 'monuments' are siliceous sinter deposits similar to the siliceous spires discovered on the floor of Yellowstone Lake. Scientists hypothesize that this basin's structures formed from a hot water system in a glacially dammed lake during the waning stages of the Pinedale Glaciation. The basin is on a ridge reached by a very steep one-mile (1.6 km) trail south of Artists' Paint Pots. Other areas of thermal activity in Gibbon Geyser Basin lie off-trail.

 

South of Norris along the rim of the caldera is the Upper Geyser Basin 44°27′52″N 110°49′45″W, which has the highest concentration of geothermal features in the park. This complement of features includes the most famous geyser in the park, Old Faithful Geyser, as well as four other predictable large geysers. One of these large geysers in the area is Castle Geyser which is about 1,400 feet (430 m) northwest of Old Faithful. Castle Geyser has an interval of approximately 13 hours between major eruptions, but is unpredictable after minor eruptions. The other three predictable geysers are Grand Geyser, Daisy Geyser, and Riverside Geyser. Biscuit Basin and Black Sand Basin are also within the boundaries of Upper Geyser Basin.

 

The hills surrounding Old Faithful and the Upper Geyser Basin are reminders of Quaternary rhyolitic lava flows. These flows, occurring long after the catastrophic eruption of 640,000 years ago, flowed across the landscape like stiff mounds of bread dough due to their high silica content.

 

Evidence of glacial activity is common, and it is one of the keys that allows geysers to exist. Glacier till deposits underlie the geyser basins providing storage areas for the water used in eruptions. Many landforms, such as Porcupine Hills north of Fountain Flats, are made up of glacial gravel and are reminders that 70,000 to 14,000 years ago, this area was buried under ice.

 

Signs of the forces of erosion can be seen everywhere, from runoff channels carved across the sinter in the geyser basins to the drainage created by the Firehole River. Mountain building is evident on the drive south of Old Faithful, toward Craig Pass. Here the Rocky Mountains reach a height of 8,262 feet (2,518 m), dividing the country into two distinct watersheds.

 

Midway Geyser Basin 44°31′04″N 110°49′56″W is much smaller than the other basins found alongside the Firehole River. Despite its small size, it contains two large features, the 200-by-300-foot-wide (60 by 90 m) Excelsior Geyser which pours over 4,000 U.S. gallons (15,000 L; 3,300 imp gal) per minute into the Firehole River. The largest hot spring in Yellowstone, the 370-foot-wide (110 m) and 121-foot-deep (37 m) Grand Prismatic Spring is found here. Also in the basin is Turquoise Pool and Opal Pool.

 

Lower Geyser Basin

Silex Spring at Fountain Paint Pot

 

Farther north is the Lower Geyser Basin 44°32′58″N 110°50′09″W, which is the largest geyser basin in area, covering approximately 11 square miles. Due to its large size, it has a much less concentrated set of geothermal features, including Fountain Paint Pots. Fountain Paint Pots are mud pots, that is, a hot spring that contains boiling mud instead of water. The mud is produced by a higher acidity in the water which enables the spring to dissolve surrounding minerals to create an opaque, usually grey, mud. Also there is Firehole Spring, Celestine Pool, Leather Pool, Red Spouter, Jelly spring, and a number of fumaroles.

 

Geysers in Lower Geyser Basin include Great Fountain Geyser, whose eruptions reach 100 to 200 feet (30–61 m) in the air, while waves of water cascade down its sinter terraces., the Fountain group of Geysers (Clepsydra Geyser which erupts nearly continuously to heights of 45 feet (14 m), Fountain Geyser, Jelly Geyser, Jet Geyser, Morning Geyser, and Spasm Geyser), the Pink Cone group of geysers (Dilemma Geyser, Labial Geyser, Narcissus Geyser, Pink Geyser, and Pink Cone Geyser), the White Dome group of geysers (Crack Geyser, Gemini Geyser, Pebble Geyser, Rejuvenated Geyser, and White Dome Geyser), as well as Sizzler Geyser.

Overflow areas of Silex springs

 

The West Thumb Geyser Basin 44°25′07″N 110°34′23″W, including Potts Basin to the north, is the largest geyser basin on the shores of Yellowstone Lake. The heat source of the thermal features in this location is thought to be relatively close to the surface, only 10,000 feet (3,000 m) down. West Thumb is about the same size as another famous volcanic caldera, Crater Lake in Oregon, but much smaller than the great Yellowstone Caldera which last erupted about 640,000 years ago. West Thumb is a caldera within a caldera.

 

West Thumb was created approximately 162,000 years ago when a magma chamber bulged up under the surface of the earth and subsequently cracked it along ring fracture zones. This in turn released the enclosed magma as lava and caused the surface above the emptied magma chamber to collapse. Water later filled the collapsed area of the caldera, forming an extension of Yellowstone Lake. This created the source of heat and water that feed the West Thumb Geyser Basin today.

 

The thermal features at West Thumb are not only found on the lake shore, but extend under the surface of the lake as well. Several underwater hydrothermal features were discovered in the early 1990s and can be seen as slick spots or slight bulges in the summer. During the winter, the underwater thermal features are visible as melt holes in the icy surface of the lake. The surrounding ice can reach three feet (one yard) in thickness.

 

Perhaps the most famous hydrothermal feature at West Thumb is a geyser on the lake shore known as Fishing Cone. Walter Trumbull of the 1870 Washburn-Langford-Doane Expedition described a unique event while a man was fishing adjacent to the cone: "...in swinging a trout ashore, it accidentally got off the hook and fell into the spring. For a moment it darted about with wonderful rapidity, as if seeking an outlet. Then it came to the top, dead, and literally boiled." Fishing Cone erupted frequently to the height of 40 feet (12 m) in 1919 and to lesser heights in 1939. One fisherman was badly burned in Fishing Cone in 1921. Fishing at the geyser is now prohibited.

 

Early visitors would arrive at West Thumb via stagecoach from the Old Faithful area. They had a choice of continuing on the stagecoach or boarding the steamship Zillah to continue the journey by water to Lake Hotel. The boat dock was located near the south end of the geyser basin near Lakeside Spring.

 

Backcountry Geyser Basins

The Heart Lake 44°18′00″N 110°30′56″W, Lone Star 44°24′50″N 110°49′04″W, and Shoshone Geyser Basins 44°21′16″N 110°47′57″W are located away from the road and require at least several miles of hiking to reach. These areas lack the boardwalks and other safety features of the developed areas. As falling into geothermal features can be fatal, it is usually advisable to visit these areas with an experienced guide or at the very least, travelers need to ensure they remain on well-marked trails.

 

The Heart Lake Geyser Basin contains several groups of geysers and deep blue hot springs near Heart Lake in the south-central portion of Yellowstone, southeast of most of the main geyser basins. Lying in the Snake River watershed east of Lewis Lake and south of Yellowstone Lake, Heart Lake was named sometime before 1871 for Hart Hunney, a hunter. Other explorers in the region incorrectly assumed that the lake's name was spelled 'heart' because of its shape. The Heart Lake Geyser Basin begins a couple miles from the lake and descends along Witch Creek to the lakeshore. Five groups of hydrothermal features comprise the basin, and all of them contain geysers, although some are dormant.

 

Between Shoshone Lake and Old Faithful is the Lone Star Geyser Basin, of which the primary feature is Lone Star Geyser, named for its isolation from the nearby geysers of the Upper Geyser Basin. The basin is reachable on foot or bicycle via a 3 mile road that is closed to vehicles.

 

The Shoshone Geyser Basin, reached by hiking or by boat, contains one of the highest concentrations of geysers in the world – more than 80 in an area 1,600 by 800 feet (490 by 240 m). Hot springs and mudpots dot the landscape between the geyser basin and Shoshone Lake.

 

Hot Spring Basin is located 15 miles (24 km) north-northeast of Fishing Bridge and has one of Yellowstone's largest collections of hot springs and fumaroles. The geothermal features there release large amounts of sulfur. This makes water from the springs so acidic that it has dissolved holes in the pants of people who sit on wet ground and causes mounds of sulfur three feet (1 m) high to develop around fumaroles. The very hot acidic water and steam have also created voids in the ground that are only covered by a thin crust.

 

Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Because of the huge amount of geothermal vents, travertine flourishes. Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas.

 

The thermal features at Mud Volcano and Sulphur Caldron are primarily mud pots and fumaroles because the area is situated on a perched water system with little water available. Fumaroles or "steam vents" occur when the ground water boils away faster than it can be recharged. Also, the vapors are rich in sulfuric acid that leaches the rock, breaking it down into clay. Because no water washes away the acid or leached rock, it remains as sticky clay to form a mud pot. Hydrogen sulfide gas is present deep in the earth at Mud Volcano and is oxidized to sulfuric acid by microbial activity, which dissolves the surface soils to create pools and cones of clay and mud. Along with hydrogen sulfide, steam, carbon dioxide, and other gases explode through the layers of mud.

 

A series of shallow earthquakes associated with the volcanic activity in Yellowstone struck this area in 1978. Soil temperatures increased to nearly 200 °F (93 °C). The slope between Sizzling Basin and Mud Geyser, once covered with green grass and trees, became a barren landscape of fallen trees known as "the cooking hillside".

 

Yellowstone National Park is a national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the 42nd U.S. Congress with the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

 

While Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the U.S. Department of the Interior, the first Secretary of the Interior to supervise the park being Columbus Delano. However, the U.S. Army was eventually commissioned to oversee the management of Yellowstone for 30 years between 1886 and 1916. In 1917, the administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.

 

Yellowstone National Park spans an area of 3,468.4 sq mi (8,983 km2), comprising lakes, canyons, rivers, and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest super volcano on the continent. The caldera is considered a dormant volcano. It has erupted with tremendous force several times in the last two million years. Well over half of the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.

 

Hundreds of species of mammals, birds, fish, reptiles, and amphibians have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the contiguous United States. Grizzly bears, cougars, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one-third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing, and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.

 

Teton County is a county in the U.S. state of Wyoming. As of the 2020 United States Census, the population was 23,331. Its county seat is Jackson. Its west boundary line is also the Wyoming state boundary shared with Idaho and the southern tip of Montana. Teton County is part of the Jackson, WY-ID Micropolitan Statistical Area.

 

Teton County contains the Jackson Hole ski area, all of Grand Teton National Park, and 40.4% of Yellowstone National Park's total area, including over 96.6% of its water area (largely in Yellowstone Lake).

 

Wyoming is a state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With a population of 576,851 in 2020, Wyoming is the least populous state despite being the 10th largest by area, with the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had an estimated population of 63,957 in 2018.

 

Wyoming's western half consists mostly of the ranges and rangelands of the Rocky Mountains; its eastern half consists of high-elevation prairie, and is referred to as the High Plains. Wyoming's climate is semi-arid in some parts and continental in others, making it drier and windier overall than other states, with greater temperature extremes. The federal government owns just under half of Wyoming's land, generally protecting it for public uses. The state ranks sixth in the amount of land—-and fifth in the proportion of its land—-that is owned by the federal government. Its federal lands include two national parks (Grand Teton and Yellowstone), two national recreation areas, two national monuments, and several national forests, as well as historic sites, fish hatcheries, and wildlife refuges.

 

Indigenous peoples inhabited the region for thousands of years. Historic and currently federally recognized tribes include the Arapaho, Crow, Lakota, and Shoshone. Part of the land that is now Wyoming came under American sovereignty via the Louisiana Purchase, part via the Oregon Treaty, and, lastly, via the Mexican Cession. With the opening of the Oregon Trail, the Mormon Trail, and the California Trail, vast numbers of pioneers travelled through parts of the state that had once been traversed mainly by fur trappers, and this spurred the establishment of forts, such as Fort Laramie, that today serve as population centers. The Transcontinental Railroad supplanted the wagon trails in 1867 with a route through southern Wyoming, bringing new settlers and the establishment of founding towns, including the state capital of Cheyenne. On March 27, 1890, Wyoming became the union's 44th state.

 

Farming and ranching, and the attendant range wars, feature prominently in the state's history. Today, Wyoming's economy is largely based on tourism and the extraction of minerals such as coal, natural gas, oil, and trona. Its agricultural commodities include barley, hay, livestock, sugar beets, wheat, and wool.

 

Wyoming was the first state to allow women the right to vote (not counting New Jersey, which had allowed it until 1807), and the right to assume elected office, as well as the first state to elect a female governor. In honor of this part of its history, its most common nickname is "The Equality State" and its official state motto is "Equal Rights". It is among the least religious states in the country, and is known for having a political culture that leans towards libertarian conservatism. The Republican presidential nominee has carried the state in every election since 1968.

Hyderabad (Listeni/ˈhaɪdərəˌbæd/ HY-dər-ə-bad; often /ˈhaɪdrəˌbæd/) is the capital of the southern Indian state of Telangana and de jure capital of Andhra Pradesh. Occupying 625 square kilometres along the banks of the Musi River, it has a population of about 6.8 million and a metropolitan population of about 7.75 million, making it the fourth most populous city and sixth most populous urban agglomeration in India. At an average altitude of 542 metres, much of Hyderabad is situated on hilly terrain around artificial lakes, including Hussain Sagar - predating the city's founding - north of the city centre.

 

Established in 1591 by Muhammad Quli Qutb Shah, Hyderabad remained under the rule of the Qutb Shahi dynasty for nearly a century before the Mughals captured the region. In 1724, Mughal viceroy Asif Jah I declared his sovereignty and created his own dynasty, known as the Nizams of Hyderabad. The Nizam's dominions became a princely state during the British Raj, and remained so for 150 years, with the city serving as its capital. The city continued as the capital of Hyderabad State after it was brought into the Indian Union in 1948, and became the capital of Andhra Pradesh after the States Reorganisation Act, 1956. Since 1956, Rashtrapati Nilayam in the city has been the winter office of the President of India. In 2014, the newly formed state of Telangana split from Andhra Pradesh and the city became joint capital of the two states, a transitional arrangement scheduled to end by 2025.

 

Relics of Qutb Shahi and Nizam rule remain visible today, with the Charminar - commissioned by Muhammad Quli Qutb Shah - coming to symbolise Hyderabad. Golconda fort is another major landmark. The influence of Mughlai culture is also evident in the city's distinctive cuisine, which includes Hyderabadi biryani and Hyderabadi haleem. The Qutb Shahis and Nizams established Hyderabad as a cultural hub, attracting men of letters from different parts of the world. Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire in the mid-19th century, with artists migrating to the city from the rest of the Indian subcontinent. While Hyderabad is losing its cultural pre-eminence, it is today, due to the Telugu film industry, the country's second-largest producer of motion pictures.

 

Hyderabad was historically known as a pearl and diamond trading centre, and it continues to be known as the City of Pearls. Many of the city's traditional bazaars, including Laad Bazaar, Begum Bazaar and Sultan Bazaar, have remained open for centuries. However, industrialisation throughout the 20th century attracted major Indian manufacturing, research and financial institutions, including Bharat Heavy Electricals Limited, the National Geophysical Research Institute and the Centre for Cellular and Molecular Biology. Special economic zones dedicated to information technology have encouraged companies from across India and around the world to set up operations and the emergence of pharmaceutical and biotechnology industries in the 1990s led to the area's naming as India's "Genome Valley". With an output of US$74 billion, Hyderabad is the fifth-largest contributor to India's overall gross domestic product.

 

HISTORY

TOPONYMY

According to John Everett-Heath, the author of Oxford Concise Dictionary of World Place Names, Hyderabad means "Haydar's city" or "lion city", from haydar (lion) and ābād (city). It was named to honour the Caliph Ali Ibn Abi Talib, who was also known as Haydar because of his lion-like valour in battles. Andrew Petersen, a scholar of Islamic architecture, says the city was originally called Baghnagar (city of gardens). One popular theory suggests that Muhammad Quli Qutb Shah, the founder of the city, named it "Bhaganagar" or "Bhāgnagar" after Bhagmati, a local nautch (dancing) girl with whom he had fallen in love. She converted to Islam and adopted the title Hyder Mahal. The city was renamed Hyderabad in her honour. According to another source, the city was named after Haidar, the son of Quli Qutb Shah.

 

EARLY AND MEDIEVAL HISTORY

Archaeologists excavating near the city have unearthed Iron Age sites that may date from 500 BCE. The region comprising modern Hyderabad and its surroundings was known as Golkonda ("shepherd's hill"), and was ruled by the Chalukya dynasty from 624 CE to 1075 CE. Following the dissolution of the Chalukya empire into four parts in the 11th century, Golkonda came under the control of the Kakatiya dynasty from 1158, whose seat of power was at Warangal, 148 km northeast of modern Hyderabad.

 

The Kakatiya dynasty was reduced to a vassal of the Khilji dynasty in 1310 after its defeat by Sultan Alauddin Khilji of the Delhi Sultanate. This lasted until 1321, when the Kakatiya dynasty was annexed by Malik Kafur, Allaudin Khilji's general. During this period, Alauddin Khilji took the Koh-i-Noor diamond, which is said to have been mined from the Kollur Mines of Golkonda, to Delhi. Muhammad bin Tughluq succeeded to the Delhi sultanate in 1325, bringing Warangal under the rule of the Tughlaq dynasty until 1347 when Ala-ud-Din Bahman Shah, a governor under bin Tughluq, rebelled against Delhi and established the Bahmani Sultanate in the Deccan Plateau, with Gulbarga, 200 km west of Hyderabad, as its capital. The Bahmani kings ruled the region until 1518 and were the first independent Muslim rulers of the Deccan.

 

Sultan Quli, a governor of Golkonda, revolted against the Bahmani Sultanate and established the Qutb Shahi dynasty in 1518; he rebuilt the mud-fort of Golconda and named the city "Muhammad nagar". The fifth sultan, Muhammad Quli Qutb Shah, established Hyderabad on the banks of the Musi River in 1591, to avoid the water shortages experienced at Golkonda. During his rule, he had the Charminar and Mecca Masjid built in the city. On 21 September 1687, the Golkonda Sultanate came under the rule of the Mughal emperor Aurangzeb after a year-long siege of the Golkonda fort. The annexed area was renamed Deccan Suba (Deccan province) and the capital was moved from Golkonda to Aurangabad, about 550 km northwest of Hyderabad.

 

MODERN HISTORY

In 1713 Farrukhsiyar, the Mughal emperor, appointed Asif Jah I to be Viceroy of the Deccan, with the title Nizam-ul-Mulk (Administrator of the Realm). In 1724, Asif Jah I defeated Mubariz Khan to establish autonomy over the Deccan Suba, named the region Hyderabad Deccan, and started what came to be known as the Asif Jahi dynasty. Subsequent rulers retained the title Nizam ul-Mulk and were referred to as Asif Jahi Nizams, or Nizams of Hyderabad. The death of Asif Jah I in 1748 resulted in a period of political unrest as his sons, backed by opportunistic neighbouring states and colonial foreign forces, contended for the throne. The accession of Asif Jah II, who reigned from 1762 to 1803, ended the instability. In 1768 he signed the treaty of Masulipatnam, surrendering the coastal region to the East India Company in return for a fixed annual rent.

 

In 1769 Hyderabad city became the formal capital of the Nizams. In response to regular threats from Hyder Ali (Dalwai of Mysore), Baji Rao I (Peshwa of the Maratha Empire), and Basalath Jung (Asif Jah II's elder brother, who was supported by the Marquis de Bussy-Castelnau), the Nizam signed a subsidiary alliance with the East India Company in 1798, allowing the British Indian Army to occupy Bolarum (modern Secunderabad) to protect the state's borders, for which the Nizams paid an annual maintenance to the British.

 

Until 1874 there were no modern industries in Hyderabad. With the introduction of railways in the 1880s, four factories were built to the south and east of Hussain Sagar lake, and during the early 20th century, Hyderabad was transformed into a modern city with the establishment of transport services, underground drainage, running water, electricity, telecommunications, universities, industries, and Begumpet Airport. The Nizams ruled their princely state from Hyderabad during the British Raj.

 

After India gained independence, the Nizam declared his intention to remain independent rather than become part of the Indian Union. The Hyderabad State Congress, with the support of the Indian National Congress and the Communist Party of India, began agitating against Nizam VII in 1948. On 17 September that year, the Indian Army took control of Hyderabad State after an invasion codenamed Operation Polo. With the defeat of his forces, Nizam VII capitulated to the Indian Union by signing an Instrument of Accession, which made him the Rajpramukh (Princely Governor) of the state until 31 October 1956. Between 1946 and 1951, the Communist Party of India fomented the Telangana uprising against the feudal lords of the Telangana region. The Constitution of India, which became effective on 26 January 1950, made Hyderabad State one of the part B states of India, with Hyderabad city continuing to be the capital. In his 1955 report Thoughts on Linguistic States, B. R. Ambedkar, then chairman of the Drafting Committee of the Indian Constitution, proposed designating the city of Hyderabad as the second capital of India because of its amenities and strategic central location. Since 1956, the Rashtrapati Nilayam in Hyderabad has been the second official residence and business office of the President of India; the President stays once a year in winter and conducts official business particularly relating to Southern India.

 

On 1 November 1956 the states of India were reorganised by language. Hyderabad state was split into three parts, which were merged with neighbouring states to form the modern states of Maharashtra, Karnataka and Andhra Pradesh. The nine Telugu- and Urdu-speaking districts of Hyderabad State in the Telangana region were merged with the Telugu-speaking Andhra State to create Andhra Pradesh,with Hyderabad as its capital. Several protests, known collectively as the Telangana movement, attempted to invalidate the merger and demanded the creation of a new Telangana state. Major actions took place in 1969 and 1972, and a third began in 2010. The city suffered several explosions: one at Dilsukhnagar in 2002 claimed two lives; terrorist bombs in May and August 2007 caused communal tension and riots; and two bombs exploded in February 2013. On 30 July 2013 the United Progressive Alliance (UPA) government of India declared that part of Andhra Pradesh would be split off to form a new Telangana state, and that Hyderabad city would be the capital city and part of Telangana, while the city would also remain the capital of Andhra Pradesh for no more than ten years. On 3 October 2013 the Union Cabinet approved the proposal, and in February 2014 both houses of Parliament passed the Telangana Bill. With the final assent of the President of India in June 2014, Telangana state was formed.

 

GEOGRAPHY

TOPOGRAPHY

Situated in the southern part of Telangana in southeastern India, Hyderabad is 1,566 kilometres south of Delhi, 699 kilometres southeast of Mumbai, and 570 kilometres north of Bangalore by road. It lies on the banks of the Musi River, in the northern part of the Deccan Plateau. Greater Hyderabad covers 625 km2, making it one of the largest metropolitan areas in India. With an average altitude of 542 metres, Hyderabad lies on predominantly sloping terrain of grey and pink granite, dotted with small hills, the highest being Banjara Hills at 672 metres. The city has numerous lakes referred to as sagar, meaning "sea". Examples include artificial lakes created by dams on the Musi, such as Hussain Sagar (built in 1562 near the city centre), Osman Sagar and Himayat Sagar. As of 1996, the city had 140 lakes and 834 water tanks (ponds).

 

CLIMATE

Hyderabad has a tropical wet and dry climate (Köppen Aw) bordering on a hot semi-arid climate (Köppen BSh). The annual mean temperature is 26.6 °C; monthly mean temperatures are 21–33 °C. Summers (March–June) are hot and humid, with average highs in the mid-to-high 30s Celsius; maximum temperatures often exceed 40 °C between April and June. The coolest temperatures occur in December and January, when the lowest temperature occasionally dips to 10 °C. May is the hottest month, when daily temperatures range from 26 to 39 °C; December, the coldest, has temperatures varying from 14.5 to 28 °C.

 

Heavy rain from the south-west summer monsoon falls between June and September, supplying Hyderabad with most of its mean annual rainfall. Since records began in November 1891, the heaviest rainfall recorded in a 24-hour period was 241.5 mm on 24 August 2000. The highest temperature ever recorded was 45.5 °C on 2 June 1966, and the lowest was 6.1 °C on 8 January 1946. The city receives 2,731 hours of sunshine per year; maximum daily sunlight exposure occurs in February.

 

CONSERVATION

Hyderabad's lakes and the sloping terrain of its low-lying hills provide habitat for an assortment of flora and fauna. The forest region in and around the city encompasses areas of ecological and biological importance, which are preserved in the form of national parks, zoos, mini-zoos and a wildlife sanctuary. Nehru Zoological Park, the city's one large zoo, is the first in India to have a lion and tiger safari park. Hyderabad has three national parks (Mrugavani National Park, Mahavir Harina Vanasthali National Park and Kasu Brahmananda Reddy National Park), and the Manjira Wildlife Sanctuary is about 50 km from the city. Hyderabad's other environmental reserves are: Kotla Vijayabhaskara Reddy Botanical Gardens, Shamirpet Lake, Hussain Sagar, Fox Sagar Lake, Mir Alam Tank and Patancheru Lake, which is home to regional birds and attracts seasonal migratory birds from different parts of the world. Organisations engaged in environmental and wildlife preservation include the Telangana Forest Department, Indian Council of Forestry Research and Education, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the Animal Welfare Board of India, the Blue Cross of Hyderabad and the University of Hyderabad.

 

ADMINISTRATION

COMMON CAPITAL OF TELANGANA AND ANDHRA PRADESH

According to the Andhra Pradesh Reorganisation Act, 2014 part 2 Section 5: "On and from the appointed day, Hyderabad in the existing State of Andhra Pradesh, shall be the common capital of the State of Telangana and the State of Andhra Pradesh for such period not exceeding ten years. After expiry of the period referred to in sub-section, Hyderabad shall be the capital of the State of Telangana and there shall be a new capital for the State of Andhra Pradesh."

 

The same sections also define that the common capital includes the existing area designated as the Greater Hyderabad Municipal Corporation under the Hyderabad Municipal Corporation Act, 1955. As stipulated in sections 3 and 18 of the Reorganisation Act, city MLAs are members of Telangana state assembly.

 

LOCAL GOVERNMENT

The Greater Hyderabad Municipal Corporation (GHMC) oversees the civic infrastructure of the city's 18 "circles", which together encompass 150 municipal wards. Each ward is represented by a corporator, elected by popular vote. The corporators elect the Mayor, who is the titular head of GHMC; executive powers rest with the Municipal Commissioner, appointed by the state government. The GHMC carries out the city's infrastructural work such as building and maintenance of roads and drains, town planning including construction regulation, maintenance of municipal markets and parks, solid waste management, the issuing of birth and death certificates, the issuing of trade licences, collection of property tax, and community welfare services such as mother and child healthcare, and pre-school and non-formal education. The GHMC was formed in April 2007 by merging the Municipal Corporation of Hyderabad (MCH) with 12 municipalities of the Hyderabad, Ranga Reddy and Medak districts covering a total area of 625 km2. In the 2009 municipal election, an alliance of the Indian National Congress and Majlis-e-Ittehadul Muslimeen formed the majority. The Secunderabad Cantonment Board is a civic administration agency overseeing an area of 40.1 km2, where there are several military camps. The Osmania University campus is administered independently by the university authority.

 

Law and order in Hyderabad city is supervised by the governor of Telangana. The jurisdiction is divided into two police commissionerates: Hyderabad and Cyberabad, which are again divided into four and five police zones respectively. Each zone is headed by a deputy commissioner.

 

The jurisdictions of the city's administrative agencies are, in ascending order of size: the Hyderabad Police area, Hyderabad district, the GHMC area ("Hyderabad city") and the area under the Hyderabad Metropolitan Development Authority (HMDA). The HMDA is an apolitical urban planning agency that covers the GHMC and its suburbs, extending to 54 mandals in five districts encircling the city. It coordinates the development activities of GHMC and suburban municipalities and manages the administration of bodies such as the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB).

 

As the seat of the government of Telangana, Hyderabad is home to the state's legislature, secretariat and high court, as well as various local government agencies. The Lower City Civil Court and the Metropolitan Criminal Court are under the jurisdiction of the High Court. The GHMC area contains 24 State Legislative Assembly constituencies, which form five constituencies of the Lok Sabha (the lower house of the Parliament of India).

 

UTILITY SERVICES

The HMWSSB regulates rainwater harvesting, sewerage services and water supply, which is sourced from several dams located in the suburbs. In 2005, the HMWSSB started operating a 116-kilometre-long water supply pipeline from Nagarjuna Sagar Dam to meet increasing demand. The Telangana Southern Power Distribution Company Limited manages electricity supply. As of October 2014, there were 15 fire stations in the city, operated by the Telangana State Disaster and Fire Response Department. The government-owned India Post has five head post offices and many sub-post offices in Hyderabad, which are complemented by private courier services.

 

POLLUTION CONTROL

Hyderabad produces around 4,500 tonnes of solid waste daily, which is transported from collection units in Imlibun, Yousufguda and Lower Tank Bund to the dumpsite in Jawaharnagar. Disposal is managed by the Integrated Solid Waste Management project which was started by the GHMC in 2010. Rapid urbanisation and increased economic activity has also led to increased industrial waste, air, noise and water pollution, which is regulated by the Telangana Pollution Control Board (TPCB). The contribution of different sources to air pollution in 2006 was: 20–50% from vehicles, 40–70% from a combination of vehicle discharge and road dust, 10–30% from industrial discharges and 3–10% from the burning of household rubbish. Deaths resulting from atmospheric particulate matter are estimated at 1,700–3,000 each year. Ground water around Hyderabad, which has a hardness of up to 1000 ppm, around three times higher than is desirable, is the main source of drinking water but the increasing population and consequent increase in demand has led to a decline in not only ground water but also river and lake levels. This shortage is further exacerbated by inadequately treated effluent discharged from industrial treatment plants polluting the water sources of the city.

 

HEALTHCARE

The Commissionerate of Health and Family Welfare is responsible for planning, implementation and monitoring of all facilities related to health and preventive services. As of 2010–11, the city had 50 government hospitals, 300 private and charity hospitals and 194 nursing homes providing around 12,000 hospital beds, fewer than half the required 25,000. For every 10,000 people in the city, there are 17.6 hospital beds, 9 specialist doctors, 14 nurses and 6 physicians. The city also has about 4,000 individual clinics and 500 medical diagnostic centres. Private clinics are preferred by many residents because of the distance to, poor quality of care at and long waiting times in government facilities, despite the high proportion of the city's residents being covered by government health insurance: 24% according to a National Family Health Survey in 2005. As of 2012, many new private hospitals of various sizes were opened or being built. Hyderabad also has outpatient and inpatient facilities that use Unani, homeopathic and Ayurvedic treatments.

 

In the 2005 National Family Health Survey, it was reported that the city's total fertility rate is 1.8, which is below the replacement rate. Only 61% of children had been provided with all basic vaccines (BCG, measles and full courses of polio and DPT), fewer than in all other surveyed cities except Meerut. The infant mortality rate was 35 per 1,000 live births, and the mortality rate for children under five was 41 per 1,000 live births. The survey also reported that a third of women and a quarter of men are overweight or obese, 49% of children below 5 years are anaemic, and up to 20% of children are underweight, while more than 2% of women and 3% of men suffer from diabetes.

 

DEMOGRAPHICS

When the GHMC was created in 2007, the area occupied by the municipality increased from 175 km2 to 625 km2. Consequently, the population increased by 87%, from 3,637,483 in the 2001 census to 6,809,970 in the 2011 census, 24% of which are migrants from elsewhere in India, making Hyderabad the nation's fourth most populous city. As of 2011, the population density is 18,480/km2. At the same 2011 census, the Hyderabad Urban Agglomeration had a population of 7,749,334, making it the sixth most populous urban agglomeration in the country. The population of the Hyderabad urban agglomeration has since been estimated by electoral officials to be 9.1 million as of early 2013 but is expected to exceed 10 million by the end of the year. There are 3,500,802 male and 3,309,168 female citizens - a sex ratio of 945 females per 1000 males, higher than the national average of 926 per 1000. Among children aged 0–6 years, 373,794 are boys and 352,022 are girls - a ratio of 942 per 1000. Literacy stands at 82.96% (male 85.96%; female 79.79%), higher than the national average of 74.04%. The socio-economic strata consist of 20% upper class, 50% middle class and 30% working class.

 

ETHNIC GROUPS, LANGUAGE AND RELIGION

Referred to as "Hyderabadi", residents of Hyderabad are predominantly Telugu and Urdu speaking people, with minority Bengali, Gujarati (including Memon), Kannada (including Nawayathi), Malayalam, Marathi, Marwari, Odia, Punjabi, Tamil and Uttar Pradeshi communities. Hadhrami Arabs, African Arabs, Armenians, Abyssinians, Iranians, Pathans and Turkish people are also present; these communities, of which the Hadhrami are the largest, declined after Hyderabad State became part of the Indian Union, as they lost the patronage of the Nizams.

 

Telugu is the official language of Hyderabad and Urdu is its second language. The Telugu dialect spoken in Hyderabad is called Telangana, and the Urdu spoken is called Dakhani. English is also used. A significant minority speak other languages, including Hindi, Marathi, Odia, Tamil, Bengali and Kannada.

 

Hindus are in the majority. Muslims are present throughout the city and predominate in and around the Old City. There are also Christian, Sikh, Jain, Buddhist and Parsi communities and iconic temples, mosques and churches can be seen. According to the 2001 census, Hyderabad district's religious make-up was: Hindus (55.41%), Muslims (41.17%), Christians (2.43%), Jains (0.43%), Sikhs (0.29%) and Buddhists (0.02%); 0.23% did not state any religion.

 

SLUMS

In the greater metropolitan area, 13% of the population live below the poverty line. According to a 2012 report submitted by GHMC to the World Bank, Hyderabad has 1,476 slums with a total population of 1.7 million, of whom 66% live in 985 slums in the "core" of the city (the part that formed Hyderabad before the April 2007 expansion) and the remaining 34% live in 491 suburban tenements. About 22% of the slum-dwelling households had migrated from different parts of India in the last decade of the 20th century, and 63% claimed to have lived in the slums for more than 10 years. Overall literacy in the slums is 60–80% and female literacy is 52–73%. A third of the slums have basic service connections, and the remainder depend on general public services provided by the government. There are 405 government schools, 267 government aided schools, 175 private schools and 528 community halls in the slum areas. According to a 2008 survey by the Centre for Good Governance, 87.6% of the slum-dwelling households are nuclear families, 18% are very poor, with an income up to ₹20000 (US$300) per annum, 73% live below the poverty line (a standard poverty line recognised by the Andhra Pradesh Government is ₹24000 (US$360) per annum), 27% of the chief wage earners (CWE) are casual labour and 38% of the CWE are illiterate. About 3.72% of the slum children aged 5–14 do not go to school and 3.17% work as child labour, of whom 64% are boys and 36% are girls. The largest employers of child labour are street shops and construction sites. Among the working children, 35% are engaged in hazardous jobs.

 

NEIGHBOURHOODS

The historic city established by Muhammad Quli Qutb Shah on the southern side of the Musi River forms the "Old City", while the "New City" encompasses the urbanised area on the northern banks. The two are connected by many bridges across the river, the oldest of which is Purana Pul ("old bridge"). Hyderabad is twinned with neighbouring Secunderabad, to which it is connected by Hussain Sagar.

 

Many historic and tourist sites lie in south central Hyderabad, such as the Charminar, the Mecca Masjid, the Salar Jung Museum, the Nizam's Museum, the Falaknuma Palace, and the traditional retail corridor comprising the Pearl Market, Laad Bazaar and Madina Circle. North of the river are hospitals, colleges, major railway stations and business areas such as Begum Bazaar, Koti, Abids, Sultan Bazaar and Moazzam Jahi Market, along with administrative and recreational establishments such as the Reserve Bank of India, the Telangana Secretariat, the Hyderabad Mint, the Telangana Legislature, the Public Gardens, the Nizam Club, the Ravindra Bharathi, the State Museum, the Birla Temple and the Birla Planetarium.

 

North of central Hyderabad lie Hussain Sagar, Tank Bund Road, Rani Gunj and the Secunderabad Railway Station. Most of the city's parks and recreational centres, such as Sanjeevaiah Park, Indira Park, Lumbini Park, NTR Gardens, the Buddha statue and Tankbund Park are located here. In the northwest part of the city there are upscale residential and commercial areas such as Banjara Hills, Jubilee Hills, Begumpet, Khairatabad and Miyapur. The northern end contains industrial areas such as Sanathnagar, Moosapet, Balanagar, Patancheru and Chanda Nagar. The northeast end is dotted with residential areas. In the eastern part of the city lie many defence research centres and Ramoji Film City. The "Cyberabad" area in the southwest and west of the city has grown rapidly since the 1990s. It is home to information technology and bio-pharmaceutical companies and to landmarks such as Hyderabad Airport, Osman Sagar, Himayath Sagar and Kasu Brahmananda Reddy National Park.

 

LANDMARKS

Heritage buildings constructed during the Qutb Shahi and Nizam eras showcase Indo-Islamic architecture influenced by Medieval, Mughal and European styles. After the 1908 flooding of the Musi River, the city was expanded and civic monuments constructed, particularly during the rule of Mir Osman Ali Khan (the VIIth Nizam), whose patronage of architecture led to him being referred to as the maker of modern Hyderabad. In 2012, the government of India declared Hyderabad the first "Best heritage city of India".

 

Qutb Shahi architecture of the 16th and early 17th centuries followed classical Persian architecture featuring domes and colossal arches. The oldest surviving Qutb Shahi structure in Hyderabad is the ruins of Golconda fort built in the 16th century. The Charminar, Mecca Masjid, Charkaman and Qutb Shahi tombs are other existing structures of this period. Among these the Charminar has become an icon of the city; located in the centre of old Hyderabad, it is a square structure with sides 20 m long and four grand arches each facing a road. At each corner stands a 56 m-high minaret. Most of the historical bazaars that still exist were constructed on the street north of Charminar towards Golconda fort. The Charminar, Qutb Shahi tombs and Golconda fort are considered to be monuments of national importance in India; in 2010 the Indian government proposed that the sites be listed for UNESCO World Heritage status.

 

Among the oldest surviving examples of Nizam architecture in Hyderabad is the Chowmahalla Palace, which was the seat of royal power. It showcases a diverse array of architectural styles, from the Baroque Harem to its Neoclassical royal court. The other palaces include Falaknuma Palace (inspired by the style of Andrea Palladio), Purani Haveli, King Kothi and Bella Vista Palace all of which were built at the peak of Nizam rule in the 19th century. During Mir Osman Ali Khan's rule, European styles, along with Indo-Islamic, became prominent. These styles are reflected in the Falaknuma Palace and many civic monuments such as the Hyderabad High Court, Osmania Hospital, Osmania University, the State Central Library, City College, the Telangana Legislature, the State Archaeology Museum, Jubilee Hall, and Hyderabad and Kachiguda railway stations. Other landmarks of note are Paigah Palace, Asman Garh Palace, Basheer Bagh Palace, Errum Manzil and the Spanish Mosque, all constructed by the Paigah family.

 

ECONOMY

Hyderabad is the largest contributor to the gross domestic product (GDP), tax and other revenues, of Telangana, and the sixth largest deposit centre and fourth largest credit centre nationwide, as ranked by the Reserve Bank of India (RBI) in June 2012. Its US$74 billion GDP made it the fifth-largest contributor city to India's overall GDP in 2011–12. Its per capita annual income in 2011 was ₹44300 (US$670). As of 2006, the largest employers in the city were the governments of Andhra Pradesh (113,098 employees) and India (85,155). According to a 2005 survey, 77% of males and 19% of females in the city were employed. The service industry remains dominant in the city, and 90% of the employed workforce is engaged in this sector.

 

Hyderabad's role in the pearl trade has given it the name "City of Pearls" and up until the 18th century, the city was also the only global trading centre for large diamonds. Industrialisation began under the Nizams in the late 19th century, helped by railway expansion that connected the city with major ports. From the 1950s to the 1970s, Indian enterprises, such as Bharat Heavy Electricals Limited (BHEL), Nuclear Fuel Complex (NFC), National Mineral Development Corporation (NMDC), Bharat Electronics (BEL), Electronics Corporation of India Limited (ECIL), Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL), Centre for Cellular and Molecular Biology (CCMB), Centre for DNA Fingerprinting and Diagnostics (CDFD), State Bank of Hyderabad (SBH) and Andhra Bank (AB) were established in the city. The city is home to Hyderabad Securities formerly known as Hyderabad Stock Exchange (HSE), and houses the regional office of the Securities and Exchange Board of India (SEBI). In 2013, the Bombay Stock Exchange (BSE) facility in Hyderabad was forecasted to provide operations and transactions services to BSE-Mumbai by the end of 2014. The growth of the financial services sector has helped Hyderabad evolve from a traditional manufacturing city to a cosmopolitan industrial service centre. Since the 1990s, the growth of information technology (IT), IT-enabled services (ITES), insurance and financial institutions has expanded the service sector, and these primary economic activities have boosted the ancillary sectors of trade and commerce, transport, storage, communication, real estate and retail.

 

Hyderabad's commercial markets are divided into four sectors: central business districts, sub-central business centres, neighbourhood business centres and local business centres. Many traditional and historic bazaars are located throughout the city, Laad Bazaar being the prominent among all is popular for selling a variety of traditional and cultural antique wares, along with gems and pearls.

 

The establishment of Indian Drugs and Pharmaceuticals Limited (IDPL), a public sector undertaking, in 1961 was followed over the decades by many national and global companies opening manufacturing and research facilities in the city. As of 2010, the city manufactured one third of India's bulk drugs and 16% of biotechnology products, contributing to its reputation as "India's pharmaceutical capital" and the "Genome Valley of India". Hyderabad is a global centre of information technology, for which it is known as Cyberabad (Cyber City). As of 2013, it contributed 15% of India's and 98% of Andhra Pradesh's exports in IT and ITES sectors and 22% of NASSCOM's total membership is from the city. The development of HITEC City, a township with extensive technological infrastructure, prompted multinational companies to establish facilities in Hyderabad. The city is home to more than 1300 IT and ITES firms, including global conglomerates such as Microsoft (operating its largest R&D campus outside the US), Google, IBM, Yahoo!, Dell, Facebook, and major Indian firms including Tech Mahindra, Infosys, Tata Consultancy Services (TCS), Polaris and Wipro. In 2009 the World Bank Group ranked the city as the second best Indian city for doing business. The city and its suburbs contain the highest number of special economic zones of any Indian city.

 

Like the rest of India, Hyderabad has a large informal economy that employs 30% of the labour force. According to a survey published in 2007, it had 40–50,000 street vendors, and their numbers were increasing. Among the street vendors, 84% are male and 16% female, and four fifths are "stationary vendors" operating from a fixed pitch, often with their own stall. Most are financed through personal savings; only 8% borrow from moneylenders. Vendor earnings vary from ₹50 (75¢ US) to ₹800 (US$12) per day. Other unorganised economic sectors include dairy, poultry farming, brick manufacturing, casual labour and domestic help. Those involved in the informal economy constitute a major portion of urban poor.

 

CULTURE

Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire. After the fall of Delhi in 1857, the migration of performing artists to the city particularly from the north and west of the Indian sub continent, under the patronage of the Nizam, enriched the cultural milieu. This migration resulted in a mingling of North and South Indian languages, cultures and religions, which has since led to a co-existence of Hindu and Muslim traditions, for which the city has become noted. A further consequence of this north–south mix is that both Telugu and Urdu are official languages of Telangana.[164] The mixing of religions has also resulted in many festivals being celebrated in Hyderabad such as Ganesh Chaturthi, Diwali and Bonalu of Hindu tradition and Eid ul-Fitr and Eid al-Adha by Muslims.

 

Traditional Hyderabadi garb also reveals a mix of Muslim and South Asian influences with men wearing sherwani and kurta - paijama and women wearing khara dupatta and salwar kameez. Muslim women also commonly wear burqas and hijabs in public. In addition to the traditional Indian and Muslim garments, increasing exposure to western cultures has led to a rise in the wearing of western style clothing among youths.

 

LITERATURE

In the past, Qutb Shahi rulers and Nizams attracted artists, architects and men of letters from different parts of the world through patronage. The resulting ethnic mix popularised cultural events such as mushairas (poetic symposia). The Qutb Shahi dynasty particularly encouraged the growth of Deccani Urdu literature leading to works such as the Deccani Masnavi and Diwan poetry, which are among the earliest available manuscripts in Urdu. Lazzat Un Nisa, a book compiled in the 15th century at Qutb Shahi courts, contains erotic paintings with diagrams for secret medicines and stimulants in the eastern form of ancient sexual arts. The reign of the Nizams saw many literary reforms and the introduction of Urdu as a language of court, administration and education. In 1824, a collection of Urdu Ghazal poetry, named Gulzar-e-Mahlaqa, authored by Mah Laqa Bai - the first female Urdu poet to produce a Diwan - was published in Hyderabad.

 

Hyderabad has continued with these traditions in its annual Hyderabad Literary Festival, held since 2010, showcasing the city's literary and cultural creativity. Organisations engaged in the advancement of literature include the Sahitya Akademi, the Urdu Academy, the Telugu Academy, the National Council for Promotion of Urdu Language, the Comparative Literature Association of India, and the Andhra Saraswata Parishad. Literary development is further aided by state institutions such as the State Central Library, the largest public library in the state which was established in 1891, and other major libraries including the Sri Krishna Devaraya Andhra Bhasha Nilayam, the British Library and the Sundarayya Vignana Kendram.

 

MUSIC AND FILMS

South Indian music and dances such as the Kuchipudi and Kathakali styles are popular in the Deccan region. As a result of their culture policies, North Indian music and dance gained popularity during the rule of the Mughals and Nizams, and it was also during their reign that it became a tradition among the nobility to associate themselves with tawaif (courtesans). These courtesans were revered as the epitome of etiquette and culture, and were appointed to teach singing, poetry and classical dance to many children of the aristocracy. This gave rise to certain styles of court music, dance and poetry. Besides western and Indian popular music genres such as filmi music, the residents of Hyderabad play city-based marfa music, dholak ke geet (household songs based on local Folklore), and qawwali, especially at weddings, festivals and other celebratory events. The state government organises the Golconda Music and Dance Festival, the Taramati Music Festival and the Premavathi Dance Festival to further encourage the development of music.

 

Although the city is not particularly noted for theatre and drama, the state government promotes theatre with multiple programmes and festivals in such venues as the Ravindra Bharati, Shilpakala Vedika and Lalithakala Thoranam. Although not a purely music oriented event, Numaish, a popular annual exhibition of local and national consumer products, does feature some musical performances. The city is home to the Telugu film industry, popularly known as Tollywood and as of 2012, produces the second largest number of films in India with the largest number being produced by Bollywood. Films in the local Hyderabadi dialect are also produced and have been gaining popularity since 2005. The city has also hosted international film festivals such as the International Children's Film Festival and the Hyderabad International Film Festival. In 2005, Guinness World Records declared Ramoji Film City to be the world's largest film studio.

 

ART AND HANDICRAFTS

The region is well known for its Golconda and Hyderabad painting styles which are branches of Deccani painting. Developed during the 16th century, the Golconda style is a native style blending foreign techniques and bears some similarity to the Vijayanagara paintings of neighbouring Mysore. A significant use of luminous gold and white colours is generally found in the Golconda style. The Hyderabad style originated in the 17th century under the Nizams. Highly influenced by Mughal painting, this style makes use of bright colours and mostly depicts regional landscape, culture, costumes and jewellery.

 

Although not a centre for handicrafts itself, the patronage of the arts by the Mughals and Nizams attracted artisans from the region to Hyderabad. Such crafts include: Bidriware, a metalwork handicraft from neighbouring Karnataka, which was popularised during the 18th century and has since been granted a Geographical Indication (GI) tag under the auspices of the WTO act; and Zari and Zardozi, embroidery works on textile that involve making elaborate designs using gold, silver and other metal threads. Another example of a handicraft drawn to Hyderabad is Kalamkari, a hand-painted or block-printed cotton textile that comes from cities in Andhra Pradesh. This craft is distinguished in having both a Hindu style, known as Srikalahasti and entirely done by hand, and an Islamic style, known as Machilipatnam that uses both hand and block techniques. Examples of Hyderabad's arts and crafts are housed in various museums including the Salar Jung Museum (housing "one of the largest one-man-collections in the world"), the AP State Archaeology Museum, the Nizam Museum, the City Museum and the Birla Science Museum.

 

CUISINE

Hyderabadi cuisine comprises a broad repertoire of rice, wheat and meat dishes and the skilled use of various spices. Hyderabadi biryani and Hyderabadi haleem, with their blend of Mughlai and Arab cuisines, have become iconic dishes of India. Hyderabadi cuisine is highly influenced by Mughlai and to some extent by French, Arabic, Turkish, Iranian and native Telugu and Marathwada cuisines. Other popular native dishes include nihari, chakna, baghara baingan and the desserts qubani ka meetha, double ka meetha and kaddu ki kheer (a sweet porridge made with sweet gourd).

 

MEDIA

One of Hyderabad's earliest newspapers, The Deccan Times, was established in the 1780s. In modern times, the major Telugu dailies published in Hyderabad are Eenadu, Andhra Jyothy, Sakshi and Namaste Telangana, while the major English papers are The Times of India, The Hindu and The Deccan Chronicle, and the major Urdu papers include The Siasat Daily, The Munsif Daily and Etemaad. Many coffee table magazines, professional magazines and research journals are also regularly published. The Secunderabad Cantonment Board established the first radio station in Hyderabad State around 1919. Deccan Radio was the first radio public broadcast station in the city starting on 3 February 1935, with FM broadcasting beginning in 2000. The available channels in Hyderabad include All India Radio, Radio Mirchi, Radio City, Red FM and Big FM.

 

Television broadcasting in Hyderabad began in 1974 with the launch of Doordarshan, the Government of India's public service broadcaster, which transmits two free-to-air terrestrial television channels and one satellite channel. Private satellite channels started in July 1992 with the launch of Star TV. Satellite TV channels are accessible via cable subscription, direct-broadcast satellite services or internet-based television. Hyderabad's first dial-up internet access became available in the early 1990s and was limited to software development companies. The first public internet access service began in 1995, with the first private sector internet service provider (ISP) starting operations in 1998. In 2015, high-speed public WiFi was introduced in parts of the city.

 

EDUCATION

Public and private schools in Hyderabad are governed by the Central Board of Secondary Education and follow a "10+2+3" plan. About two-thirds of pupils attend privately run institutions. Languages of instruction include English, Hindi, Telugu and Urdu. Depending on the institution, students are required to sit the Secondary School Certificate or the Indian Certificate of Secondary Education. After completing secondary education, students enroll in schools or junior colleges with a higher secondary facility. Admission to professional graduation colleges in Hyderabad, many of which are affiliated with either Jawaharlal Nehru Technological University Hyderabad (JNTUH) or Osmania University (OU), is through the Engineering Agricultural and Medical Common Entrance Test (EAM-CET).There are 13 universities in Hyderabad: two private universities, two deemed universities, six state universities and three central universities. The central universities are the University of Hyderabad, Maulana Azad National Urdu University and the English and Foreign Languages University. Osmania University, established in 1918, was the first university in Hyderabad and as of 2012 is India's second most popular institution for international students. The Dr. B. R. Ambedkar Open University, established in 1982, is the first distance learning open university in India.

 

Hyderabad is also home to a number of centres specialising in particular fields such as biomedical sciences, biotechnology and pharmaceuticals, such as the National Institute of Pharmaceutical Education and Research (NIPER) and National Institute of Nutrition (NIN). Hyderabad has five major medical schools - Osmania Medical College, Gandhi Medical College, Nizam's Institute of Medical Sciences, Deccan College of Medical Sciences and Shadan Institute of Medical Sciences - and many affiliated teaching hospitals. The Government Nizamia Tibbi College is a college of Unani medicine. Hyderabad is also the headquarters of the Indian Heart Association, a non-profit foundation for cardiovascular education.

 

Institutes in Hyderabad include the National Institute of Rural Development, the Indian School of Business, the Institute of Public Enterprise, the Administrative Staff College of India and the Sardar Vallabhbhai Patel National Police Academy. Technical and engineering schools include the International Institute of Information Technology, Hyderabad (IIITH), Birla Institute of Technology and Science, Pilani – Hyderabad (BITS Hyderabad) and Indian Institute of Technology, Hyderabad (IIT-H) as well as agricultural engineering institutes such as the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and the Acharya N. G. Ranga Agricultural University. Hyderabad also has schools of fashion design including Raffles Millennium International, NIFT Hyderabad and Wigan and Leigh College. The National Institute of Design, Hyderabad (NID-H), will offer undergraduate and postgraduate courses from 2015.

 

SPORTS

The most popular sports played in Hyderabad are cricket and association football. At the professional level, the city has hosted national and international sports events such as the 2002 National Games of India, the 2003 Afro-Asian Games, the 2004 AP Tourism Hyderabad Open women's tennis tournament, the 2007 Military World Games, the 2009 World Badminton Championships and the 2009 IBSF World Snooker Championship. The city hosts a number of venues suitable for professional competition such as the Swarnandhra Pradesh Sports Complex for field hockey, the G. M. C. Balayogi Stadium in Gachibowli for athletics and football, and for cricket, the Lal Bahadur Shastri Stadium and Rajiv Gandhi International Cricket Stadium, home ground of the Hyderabad Cricket Association. Hyderabad has hosted many international cricket matches, including matches in the 1987 and the 1996 ICC Cricket World Cups. The Hyderabad cricket team represents the city in the Ranji Trophy - a first-class cricket tournament among India's states and cities. Hyderabad is also home to the Indian Premier League franchise Sunrisers Hyderabad. A previous franchise was the Deccan Chargers, which won the 2009 Indian Premier League held in South Africa.

 

During British rule, Secunderabad became a well-known sporting centre and many race courses, parade grounds and polo fields were built. Many elite clubs formed by the Nizams and the British such as the Secunderabad Club, the Nizam Club and the Hyderabad Race Club, which is known for its horse racing especially the annual Deccan derby, still exist. In more recent times, motorsports has become popular with the Andhra Pradesh Motor Sports Club organising popular events such as the Deccan 1/4 Mile Drag, TSD Rallies and 4x4 off-road rallying.

 

International-level sportspeople from Hyderabad include: cricketers Ghulam Ahmed, M. L. Jaisimha, Mohammed Azharuddin, V. V. S. Laxman, Venkatapathy Raju, Shivlal Yadav, Arshad Ayub and Noel David; football players Syed Abdul Rahim, Syed Nayeemuddin and Shabbir Ali; tennis player Sania Mirza; badminton players S. M. Arif, Pullela Gopichand, Saina Nehwal, P. V. Sindhu, Jwala Gutta and Chetan Anand; hockey players Syed Mohammad Hadi and Mukesh Kumar; rifle shooters Gagan Narang and Asher Noria and bodybuilder Mir Mohtesham Ali Khan.

 

TRANSPORT

The most commonly used forms of medium distance transport in Hyderabad include government owned services such as light railways and buses, as well as privately operated taxis and auto rickshaws. Bus services operate from the Mahatma Gandhi Bus Station in the city centre and carry over 130 million passengers daily across the entire network. Hyderabad's light rail transportation system, the Multi-Modal Transport System (MMTS), is a three line suburban rail service used by over 160,000 passengers daily. Complementing these government services are minibus routes operated by Setwin (Society for Employment Promotion & Training in Twin Cities). Intercity rail services also operate from Hyderabad; the main, and largest, station is Secunderabad Railway Station, which serves as Indian Railways' South Central Railway zone headquarters and a hub for both buses and MMTS light rail services connecting Secunderabad and Hyderabad. Other major railway stations in Hyderabad are Hyderabad Deccan Station, Kachiguda Railway Station, Begumpet Railway Station, Malkajgiri Railway Station and Lingampally Railway Station. The Hyderabad Metro, a new rapid transit system, is to be added to the existing public transport infrastructure and is scheduled to operate three lines by 2015. As of 2012, there are over 3.5 million vehicles operating in the city, of which 74% are two-wheelers, 15% cars and 3% three-wheelers. The remaining 8% include buses, goods vehicles and taxis. The large number of vehicles coupled with relatively low road coverage - roads occupy only 9.5% of the total city area - has led to widespread traffic congestion especially since 80% of passengers and 60% of freight are transported by road. The Inner Ring Road, the Outer Ring Road, the Hyderabad Elevated Expressway, the longest flyover in India, and various interchanges, overpasses and underpasses were built to ease the congestion. Maximum speed limits within the city are 50 km/h for two-wheelers and cars, 35 km/h for auto rickshaws and 40 km/h for light commercial vehicles and buses.

 

Hyderabad sits at the junction of three National Highways linking it to six other states: NH-7 runs 2,369 km from Varanasi, Uttar Pradesh, in the north to Kanyakumari, Tamil Nadu, in the south; NH-9, runs 841 km east-west between Machilipatnam, Andhra Pradesh, and Pune, Maharashtra; and the 280 km NH-163 links Hyderabad to Bhopalpatnam, Chhattisgarh. Five state highways, SH-1, SH-2, SH-4, SH-5 and SH-6, either start from, or pass through, Hyderabad.

 

Air traffic was previously handled via Begumpet Airport, but this was replaced by Rajiv Gandhi International Airport (RGIA) (IATA: HYD, ICAO: VOHS) in 2008, with the capacity of handling 12 million passengers and 100,000 tonnes of cargo per annum. In 2011, Airports Council International, an autonomous body representing the world's airports, judged RGIA the world's best airport in the 5–15 million passenger category and the world's fifth best airport for service quality.

Testosterone is the primary male sex hormone and an anabolic steroid. In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.[2] In addition, testosterone is involved in health and well-being,[3] and the prevention of osteoporosis.[4] Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss.

 

Testosterone is a steroid from the androstane class containing a keto and hydroxyl groups at the three and seventeen positions respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites.[5] It exerts its action through binding to and activation of the androgen receptor.[5] In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. On average, in adult males, levels of testosterone are about 7 to 8 times as great as in adult females.[6] As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men.[7][8] Females are also more sensitive to the hormone.[9]

 

In addition to its role as a natural hormone, testosterone is used as a medication, for instance in the treatment of low testosterone levels in men and breast cancer in women.[10] Since testosterone levels decrease as men age, testosterone is sometimes used in older men to counteract this deficiency. It is also used illicitly to enhance physique and performance, for instance in athletes.

Biological effects[edit]

In general, androgens such as testosterone promote protein synthesis and thus growth of tissues with androgen receptors.[11] Testosterone can be described as having virilising and anabolic effects (though these categorical descriptions are somewhat arbitrary, as there is a great deal of mutual overlap between them).[12]

 

Anabolic effects include growth of muscle mass and strength, increased bone density and strength, and stimulation of linear growth and bone maturation.

Androgenic effects include maturation of the sex organs, particularly the penis and the formation of the scrotum in the fetus, and after birth (usually at puberty) a deepening of the voice, growth of facial hair (such as the beard) and axillary (underarm) hair. Many of these fall into the category of male secondary sex characteristics.

Testosterone effects can also be classified by the age of usual occurrence. For postnatal effects in both males and females, these are mostly dependent on the levels and duration of circulating free testosterone.

 

Before birth[edit]

Effects before birth are divided into two categories, classified in relation to the stages of development.

 

The first period occurs between 4 and 6 weeks of the gestation. Examples include genital virilisation such as midline fusion, phallic urethra, scrotal thinning and rugation, and phallic enlargement; although the role of testosterone is far smaller than that of dihydrotestosterone. There is also development of the prostate gland and seminal vesicles.

 

During the second trimester, androgen level is associated with sex formation.[13] This period affects the femininization or masculinization of the fetus and can be a better predictor of feminine or masculine behaviours such as sex typed behaviour than an adult's own levels. A mother's testosterone level during pregnancy is correlated with her daughter's sex-typical behavior as an adult, and the correlation is even stronger than with the daughter's own adult testosterone level.[14]

 

Early infancy[edit]

Early infancy androgen effects are the least understood. In the first weeks of life for male infants, testosterone levels rise. The levels remain in a pubertal range for a few months, but usually reach the barely detectable levels of childhood by 4–7 months of age.[15][16] The function of this rise in humans is unknown. It has been theorized that brain masculinization is occurring since no significant changes have been identified in other parts of the body.[17] The male brain is masculinized by the aromatization of testosterone into estrogen, which crosses the blood–brain barrier and enters the male brain, whereas female fetuses have α-fetoprotein, which binds the estrogen so that female brains are not affected.[18]

 

Before puberty[edit]

Before puberty effects of rising androgen levels occur in both boys and girls. These include adult-type body odor, increased oiliness of skin and hair, acne, pubarche (appearance of pubic hair), axillary hair (armpit hair), growth spurt, accelerated bone maturation, and facial hair.[19]

 

Pubertal[edit]

Pubertal effects begin to occur when androgen has been higher than normal adult female levels for months or years. In males, these are usual late pubertal effects, and occur in women after prolonged periods of heightened levels of free testosterone in the blood. The effects include:[19][20]

 

Growth of spermatogenic tissue in testicles, male fertility, penis or clitoris enlargement, increased libido and frequency of erection or clitoral engorgement occurs. Growth of jaw, brow, chin, and nose and remodeling of facial bone contours, in conjunction with human growth hormone occurs.[21] Completion of bone maturation and termination of growth. This occurs indirectly via estradiol metabolites and hence more gradually in men than women. Increased muscle strength and mass, shoulders become broader and rib cage expands, deepening of voice, growth of the Adam's apple. Enlargement of sebaceous glands. This might cause acne, subcutaneous fat in face decreases. Pubic hair extends to thighs and up toward umbilicus, development of facial hair (sideburns, beard, moustache), loss of scalp hair (androgenetic alopecia), increase in chest hair, periareolar hair, perianal hair, leg hair, armpit hair.

 

Adult[edit]

Testosterone is necessary for normal sperm development. It activates genes in Sertoli cells, which promote differentiation of spermatogonia. It regulates acute HPA (hypothalamic–pituitary–adrenal axis) response under dominance challenge.[22] Androgen including testosterone enhances muscle growth. Testosterone also regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and hence platelet aggregation in humans.[23][24]

 

Adult testosterone effects are more clearly demonstrable in males than in females, but are likely important to both sexes. Some of these effects may decline as testosterone levels might decrease in the later decades of adult life.[25]

 

Health risks[edit]

Testosterone does not appear to increase the risk of developing prostate cancer. In people who have undergone testosterone deprivation therapy, testosterone increases beyond the castrate level have been shown to increase the rate of spread of an existing prostate cancer.[26][27][28]

 

Conflicting results have been obtained concerning the importance of testosterone in maintaining cardiovascular health.[29][30] Nevertheless, maintaining normal testosterone levels in elderly men has been shown to improve many parameters that are thought to reduce cardiovascular disease risk, such as increased lean body mass, decreased visceral fat mass, decreased total cholesterol, and glycemic control.[31]

 

High androgen levels are associated with menstrual cycle irregularities in both clinical populations and healthy women.[32]

 

Sexual arousal[edit]

See also: Hormones and sexual arousal

When testosterone and endorphins in ejaculated semen meet the cervical wall after sexual intercourse, females receive a spike in testosterone, endorphin, and oxytocin levels, and males after orgasm during copulation experience an increase in endorphins and a marked increase in oxytocin levels. This adds to the hospitable physiological environment in the female internal reproductive tract for conceiving, and later for nurturing the conceptus in the pre-embryonic stages, and stimulates feelings of love, desire, and paternal care in the male (this is the only time male oxytocin levels rival a female's).[citation needed]

 

Testosterone levels follow a nyctohemeral rhythm that peaks early each day, regardless of sexual activity.[33]

 

There are positive correlations between positive orgasm experience in women and testosterone levels where relaxation was a key perception of the experience. There is no correlation between testosterone and men's perceptions of their orgasm experience, and also no correlation between higher testosterone levels and greater sexual assertiveness in either sex.[34]

 

Sexual arousal and masturbation in women produce small increases in testosterone concentrations.[35] The plasma levels of various steroids significantly increase after masturbation in men and the testosterone levels correlate to those levels.[36]

 

Mammalian studies[edit]

Studies conducted in rats have indicated that their degree of sexual arousal is sensitive to reductions in testosterone. When testosterone-deprived rats were given medium levels of testosterone, their sexual behaviors (copulation, partner preference, etc.) resumed, but not when given low amounts of the same hormone. Therefore, these mammals may provide a model for studying clinical populations among humans suffering from sexual arousal deficits such as hypoactive sexual desire disorder.[37]

 

In every mammalian species examined demonstrated a marked increase in a male's testosterone level upon encountering a novel female. The reflexive testosterone increases in male mice is related to the male's initial level of sexual arousal.[38]

 

In non-human primates, it may be that testosterone in puberty stimulates sexual arousal, which allows the primate to increasingly seek out sexual experiences with females and thus creates a sexual preference for females.[39] Some research has also indicated that if testosterone is eliminated in an adult male human or other adult male primate's system, its sexual motivation decreases, but there is no corresponding decrease in ability to engage in sexual activity (mounting, ejaculating, etc.).[39]

 

In accordance with sperm competition theory, testosterone levels are shown to increase as a response to previously neutral stimuli when conditioned to become sexual in male rats.[40] This reaction engages penile reflexes (such as erection and ejaculation) that aid in sperm competition when more than one male is present in mating encounters, allowing for more production of successful sperm and a higher chance of reproduction.

 

Males[edit]

In men, higher levels of testosterone are associated with periods of sexual activity.[41][42]

 

Men who watch a sexually explicit movie have an average increase of 35% in testosterone, peaking at 60–90 minutes after the end of the film, but no increase is seen in men who watch sexually neutral films.[43] Men who watch sexually explicit films also report increased motivation, competitiveness, and decreased exhaustion.[44] A link has also been found between relaxation following sexual arousal and testosterone levels.[45]

 

Men's levels of testosterone, a hormone known to affect men's mating behaviour, changes depending on whether they are exposed to an ovulating or nonovulating woman's body odour. Men who are exposed to scents of ovulating women maintained a stable testosterone level that was higher than the testosterone level of men exposed to nonovulation cues. Testosterone levels and sexual arousal in men are heavily aware of hormone cycles in females.[46] This may be linked to the ovulatory shift hypothesis,[47] where males are adapted to respond to the ovulation cycles of females by sensing when they are most fertile and whereby females look for preferred male mates when they are the most fertile; both actions may be driven by hormones.

 

Females[edit]

Androgens may modulate the physiology of vaginal tissue and contribute to female genital sexual arousal.[48] Women's level of testosterone is higher when measured pre-intercourse vs pre-cuddling, as well as post-intercourse vs post-cuddling.[49] There is a time lag effect when testosterone is administered, on genital arousal in women. In addition, a continuous increase in vaginal sexual arousal may result in higher genital sensations and sexual appetitive behaviors.[50]

 

When females have a higher baseline level of testosterone, they have higher increases in sexual arousal levels but smaller increases in testosterone, indicating a ceiling effect on testosterone levels in females. Sexual thoughts also change the level of testosterone but not level of cortisol in the female body, and hormonal contraceptives may affect the variation in testosterone response to sexual thoughts.[51]

 

Testosterone may prove to be an effective treatment in female sexual arousal disorders,[52] and is available as a dermal patch. There is no FDA approved androgen preparation for the treatment of androgen insufficiency; however, it has been used off-label to treat low libido and sexual dysfunction in older women. Testosterone may be a treatment for postmenopausal women as long as they are effectively estrogenized.[52]

 

Romantic relationships[edit]

Falling in love decreases men's testosterone levels while increasing women's testosterone levels. There has been speculation that these changes in testosterone result in the temporary reduction of differences in behavior between the sexes.[53] However, it is suggested that after the "honeymoon phase" ends—about four years into a relationship—this change in testosterone levels is no longer apparent.[53] Men who produce less testosterone are more likely to be in a relationship[54] or married,[55] and men who produce more testosterone are more likely to divorce;[55] however, causality cannot be determined in this correlation. Marriage or commitment could cause a decrease in testosterone levels.[56] Single men who have not had relationship experience have lower testosterone levels than single men with experience. It is suggested that these single men with prior experience are in a more competitive state than their non-experienced counterparts.[57] Married men who engage in bond-maintenance activities such as spending the day with their spouse/and or child have no different testosterone levels compared to times when they do not engage in such activities. Collectively, these results suggest that the presence of competitive activities rather than bond-maintenance activities are more relevant to changes in testosterone levels.[58]

 

Men who produce more testosterone are more likely to engage in extramarital sex.[55] Testosterone levels do not rely on physical presence of a partner; testosterone levels of men engaging in same-city and long-distance relationships are similar.[54] Physical presence may be required for women who are in relationships for the testosterone–partner interaction, where same-city partnered women have lower testosterone levels than long-distance partnered women.[59]

 

Fatherhood[edit]

Fatherhood decreases testosterone levels in men, suggesting that the emotions and behavior tied to decreased testosterone promote paternal care. In humans and other species that utilize allomaternal care, paternal investment in offspring is beneficial to said offspring's survival because it allows the parental dyad to raise multiple children simultaneously. This increases the reproductive fitness of the parents, because their offspring are more likely to survive and reproduce. Paternal care increases offspring survival due to increased access to higher quality food and reduced physical and immunological threats.[60] This is particularly beneficial for humans since offspring are dependent on parents for extended periods of time and mothers have relatively short inter-birth intervals.[61] While extent of paternal care varies between cultures, higher investment in direct child care has been seen to be correlated with lower average testosterone levels as well as temporary fluctuations.[62] For instance, fluctuation in testosterone levels when a child is in distress has been found to be indicative of fathering styles. If a father's testosterone levels decrease in response to hearing their baby cry, it is an indication of empathizing with the baby. This is associated with increased nurturing behavior and better outcomes for the infant.[63]

 

Motivation[edit]

Testosterone levels play a major role in risk-taking during financial decisions.[64][65]

 

Aggression and criminality [edit]

See also: Aggression § Testosterone, and Biosocial criminology

Most studies support a link between adult criminality and testosterone, although the relationship is modest if examined separately for each sex. Nearly all studies of juvenile delinquency and testosterone are not significant. Most studies have also found testosterone to be associated with behaviors or personality traits linked with criminality such as antisocial behavior and alcoholism. Many studies have also been done on the relationship between more general aggressive behavior/feelings and testosterone. About half the studies have found a relationship and about half no relationship.[66]

 

Testosterone is only one of many factors that influence aggression and the effects of previous experience and environmental stimuli have been found to correlate more strongly. A few studies indicate that the testosterone derivative estradiol (one form of estrogen) might play an important role in male aggression.[66][67][68][69] Studies have also found that testosterone facilitates aggression by modulating vasopressin receptors in the hypothalamus.[70]

 

The sexual hormone can encourage fair behavior. For the study, subjects took part in a behavioral experiment where the distribution of a real amount of money was decided. The rules allowed both fair and unfair offers. The negotiating partner could subsequently accept or decline the offer. The fairer the offer, the less probable a refusal by the negotiating partner. If no agreement was reached, neither party earned anything. Test subjects with an artificially enhanced testosterone level generally made better, fairer offers than those who received placebos, thus reducing the risk of a rejection of their offer to a minimum. Two later studies have empirically confirmed these results.[71][72][73] However men with high testosterone were significantly 27% less generous in an ultimatum game.[74] The Annual NY Academy of Sciences has also found anabolic steroid use which increase testosterone to be higher in teenagers, and this was associated with increased violence.[75] Studies have also found administered testosterone to increase verbal aggression and anger in some participants.[76]

 

Testosterone is significantly correlated with aggression and competitive behaviour and is directly facilitated by the latter. There are two theories on the role of testosterone in aggression and competition.[77] The first one is the challenge hypothesis which states that testosterone would increase during puberty thus facilitating reproductive and competitive behaviour which would include aggression.[77] Thus it is the challenge of competition among males of the species that facilitates aggression and violence.[77] Studies conducted have found direct correlation between testosterone and dominance especially among the most violent criminals in prison who had the highest testosterone levels.[77] The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.[77]

 

The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".[78][79] Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.[78] The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.[80] Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.[81][82][83][84][85]

 

The rise in testosterone levels during competition predicted aggression in males but not in females.[86] Subjects who interacted with hand guns and an experimental game showed rise in testosterone and aggression.[87] Natural selection might have evolved males to be more sensitive to competitive and status challenge situations and that the interacting roles of testosterone are the essential ingredient for aggressive behaviour in these situations.[88] Testosterone produces aggression by activating subcortical areas in the brain, which may also be inhibited or suppressed by social norms or familial situations while still manifesting in diverse intensities and ways through thoughts, anger, verbal aggression, competition, dominance and physical violence.[89] Testosterone mediates attraction to cruel and violent cues in men by promoting extended viewing of violent stimuli.[90] Testosterone specific structural brain characteristic can predict aggressive behaviour in individuals.[91]

 

Estradiol is known to correlate with aggression in male mice.[92] Moreover, the conversion of testosterone to estradiol regulates male aggression in sparrows during breeding season.[93] Rats who were given anabolic steroids that increase testosterone were also more physically aggressive to provocation as a result of "threat sensitivity".[94]

 

Brain[edit]

The brain is also affected by this sexual differentiation;[13] the enzyme aromatase converts testosterone into estradiol that is responsible for masculinization of the brain in male mice. In humans, masculinization of the fetal brain appears, by observation of gender preference in patients with congenital diseases of androgen formation or androgen receptor function, to be associated with functional androgen receptors.[95]

 

There are some differences between a male and female brain (possibly the result of different testosterone levels), one of them being size: the male human brain is, on average, larger.[96] Men were found to have a total myelinated fiber length of 176 000 km at the age of 20, whereas in women the total length was 149 000 km (approx. 15% less).[97]

 

No immediate short term effects on mood or behavior were found from the administration of supraphysiologic doses of testosterone for 10 weeks on 43 healthy men.[98] A correlation between testosterone and risk tolerance in career choice exists among women.[64][99]

 

Attention, memory, and spatial ability are key cognitive functions affected by testosterone in humans. Preliminary evidence suggests that low testosterone levels may be a risk factor for cognitive decline and possibly for dementia of the Alzheimer's type,[100][101][102][103] a key argument in life extension medicine for the use of testosterone in anti-aging therapies. Much of the literature, however, suggests a curvilinear or even quadratic relationship between spatial performance and circulating testosterone,[104] where both hypo- and hypersecretion (deficient- and excessive-secretion) of circulating androgens have negative effects on cognition.

 

Medical use[edit]

Main article: Testosterone (medication)

Testosterone is used as a medication for the treatment of males with too little or no natural testosterone production, certain forms of breast cancer,[10] and gender dysphoria in transgender men. This is known as hormone replacement therapy (HRT) or testosterone replacement therapy (TRT), which maintains serum testosterone levels in the normal range. Decline of testosterone production with age has led to interest in androgen replacement therapy.[105] It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful.[106]

 

Testosterone is included in the World Health Organization's list of essential medicines, which are the most important medications needed in a basic health system.[107] It is available as a generic medication.[10] The price depends on the form of testosterone used.[108] It can be administered as a cream or transdermal patch that is applied to the skin, by injection into a muscle, as a tablet that is placed in the cheek, or by ingestion.[10]

 

Common side effects from testosterone medication include acne, swelling, and breast enlargement in males.[10] Serious side effects may include liver toxicity, heart disease, and behavioral changes.[10] Women and children who are exposed may develop virilization.[10] It is recommended that individuals with prostate cancer not use the medication.[10] It can cause harm if used during pregnancy or breastfeeding.[10]

 

Biological activity[edit]

Steroid hormone activity[edit]

The effects of testosterone in humans and other vertebrates occur by way of multiple mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors.[109][110] Androgens such as testosterone have also been found to bind to and activate membrane androgen receptors.[111][112][113]

 

Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T.[114] The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.

 

Androgen receptors occur in many different vertebrate body system tissues, and both males and females respond similarly to similar levels. Greatly differing amounts of testosterone prenatally, at puberty, and throughout life account for a share of biological differences between males and females.

 

The bones and the brain are two important tissues in humans where the primary effect of testosterone is by way of aromatization to estradiol. In the bones, estradiol accelerates ossification of cartilage into bone, leading to closure of the epiphyses and conclusion of growth. In the central nervous system, testosterone is aromatized to estradiol. Estradiol rather than testosterone serves as the most important feedback signal to the hypothalamus (especially affecting LH secretion).[115] In many mammals, prenatal or perinatal "masculinization" of the sexually dimorphic areas of the brain by estradiol derived from testosterone programs later male sexual behavior.[116]

 

Neurosteroid activity[edit]

Testosterone, via its active metabolite 3α-androstanediol, is a potent positive allosteric modulator of the GABAA receptor.[117]

 

Testosterone has been found to act as an antagonist of the TrkA and p75NTR, receptors for the neurotrophin nerve growth factor (NGF), with high affinity (around 5 nM).[118][119][120] In contrast to testosterone, DHEA and DHEA sulfate have been found to act as high-affinity agonists of these receptors.[118][119][120]

 

Testosterone is an antagonist of the sigma σ1 receptor (Ki = 1,014 or 201 nM).[121] However, the concentrations of testosterone required for binding the receptor are far above even total circulating concentrations of testosterone in adult males (which range between 10 and 35 nM).[122]

 

Biochemistry[edit]

Biosynthesis[edit]

Like other steroid hormones, testosterone is derived from cholesterol (see figure).[124] The first step in the biosynthesis involves the oxidative cleavage of the side-chain of cholesterol by cholesterol side-chain cleavage enzyme (P450scc, CYP11A1), a mitochondrial cytochrome P450 oxidase with the loss of six carbon atoms to give pregnenolone. In the next step, two additional carbon atoms are removed by the CYP17A1 (17α-hydroxylase/17,20-lyase) enzyme in the endoplasmic reticulum to yield a variety of C19 steroids.[125] In addition, the 3β-hydroxyl group is oxidized by 3β-hydroxysteroid dehydrogenase to produce androstenedione. In the final and rate limiting step, the C17 keto group androstenedione is reduced by 17β-hydroxysteroid dehydrogenase to yield testosterone.

 

The largest amounts of testosterone (>95%) are produced by the testes in men,[2] while the adrenal glands account for most of the remainder. Testosterone is also synthesized in far smaller total quantities in women by the adrenal glands, thecal cells of the ovaries, and, during pregnancy, by the placenta.[126] In the testes, testosterone is produced by the Leydig cells.[127] The male generative glands also contain Sertoli cells, which require testosterone for spermatogenesis. Like most hormones, testosterone is supplied to target tissues in the blood where much of it is transported bound to a specific plasma protein, sex hormone-binding globulin (SHBG).

 

Regulation[edit]

 

Hypothalamic–pituitary–testicular axis

In males, testosterone is synthesized primarily in Leydig cells. The number of Leydig cells in turn is regulated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In addition, the amount of testosterone produced by existing Leydig cells is under the control of LH, which regulates the expression of 17β-hydroxysteroid dehydrogenase.[128]

 

The amount of testosterone synthesized is regulated by the hypothalamic–pituitary–testicular axis (see figure to the right).[129] When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. These latter two hormones stimulate the testis to synthesize testosterone. Finally, increasing levels of testosterone through a negative feedback loop act on the hypothalamus and pituitary to inhibit the release of GnRH and FSH/LH, respectively.

 

Factors affecting testosterone levels may include:

 

Age: Testosterone levels gradually reduce as men age.[130][131] This effect is sometimes referred to as andropause or late-onset hypogonadism.[132]

Exercise: Resistance training increases testosterone levels,[133] however, in older men, that increase can be avoided by protein ingestion.[134] Endurance training in men may lead to lower testosterone levels.[135]

Nutrients: Vitamin A deficiency may lead to sub-optimal plasma testosterone levels.[136] The secosteroid vitamin D in levels of 400–1000 IU/d (10–25 µg/d) raises testosterone levels.[137] Zinc deficiency lowers testosterone levels[138] but over-supplementation has no effect on serum testosterone.[139]

Weight loss: Reduction in weight may result in an increase in testosterone levels. Fat cells synthesize the enzyme aromatase, which converts testosterone, the male sex hormone, into estradiol, the female sex hormone.[140] However no clear association between body mass index and testosterone levels has been found.[141]

Miscellaneous: Sleep: (REM sleep) increases nocturnal testosterone levels.[142] Behavior: Dominance challenges can, in some cases, stimulate increased testosterone release in men.[143] Drugs: Natural or man-made antiandrogens including spearmint tea reduce testosterone levels.[144][145][146] Licorice can decrease the production of testosterone and this effect is greater in females.[147]

Distribution[edit]

The plasma protein binding of testosterone is 98.0 to 98.5%, with 1.5 to 2.0% free or unbound.[148] It is bound 65% to sex hormone-binding globulin (SHBG) and 33% bound weakly to albumin.[149]

Metabolism[edit]

vte Testosterone metabolism in humans

Testosterone structures

The image above contains clickable linksTestosterone metabolism in humans. Conjugation (sulfation and glucuronidation) occurs both with testosterone and with all of the other steroids that have one or more available hydroxyl (-OH) groups in this diagram.

Both testosterone and 5α-DHT are metabolized mainly in the liver.[1][151] Approximately 50% of testosterone is metabolized via conjugation into testosterone glucuronide and to a lesser extent testosterone sulfate by glucuronosyltransferases and sulfotransferases, respectively.[1] An additional 40% of testosterone is metabolized in equal proportions into the 17-ketosteroids androsterone and etiocholanolone via the combined actions of 5α- and 5β-reductases, 3α-hydroxysteroid dehydrogenase, and 17β-HSD, in that order.[1][151][152] Androsterone and etiocholanolone are then glucuronidated and to a lesser extent sulfated similarly to testosterone.[1][151] The conjugates of testosterone and its hepatic metabolites are released from the liver into circulation and excreted in the urine and bile.[1][151][152] Only a small fraction (2%) of testosterone is excreted unchanged in the urine.[151]

 

In the hepatic 17-ketosteroid pathway of testosterone metabolism, testosterone is converted in the liver by 5α-reductase and 5β-reductase into 5α-DHT and the inactive 5β-DHT, respectively.[1][151] Then, 5α-DHT and 5β-DHT are converted by 3α-HSD into 3α-androstanediol and 3α-etiocholanediol, respectively.[1][151] Subsequently, 3α-androstanediol and 3α-etiocholanediol are converted by 17β-HSD into androsterone and etiocholanolone, which is followed by their conjugation and excretion.[1][151] 3β-Androstanediol and 3β-etiocholanediol can also be formed in this pathway when 5α-DHT and 5β-DHT are acted upon by 3β-HSD instead of 3α-HSD, respectively, and they can then be transformed into epiandrosterone and epietiocholanolone, respectively.[153][154] A small portion of approximately 3% of testosterone is reversibly converted in the liver into androstenedione by 17β-HSD.[152]

 

In addition to conjugation and the 17-ketosteroid pathway, testosterone can also be hydroxylated and oxidized in the liver by cytochrome P450 enzymes, including CYP3A4, CYP3A5, CYP2C9, CYP2C19, and CYP2D6.[155] 6β-Hydroxylation and to a lesser extent 16β-hydroxylation are the major transformations.[155] The 6β-hydroxylation of testosterone is catalyzed mainly by CYP3A4 and to a lesser extent CYP3A5 and is responsible for 75 to 80% of cytochrome P450-mediated testosterone metabolism.[155] In addition to 6β- and 16β-hydroxytestosterone, 1β-, 2α/β-, 11β-, and 15β-hydroxytestosterone are also formed as minor metabolites.[155][156] Certain cytochrome P450 enzymes such as CYP2C9 and CYP2C19 can also oxidize testosterone at the C17 position to form androstenedione.[155]

 

Two of the immediate metabolites of testosterone, 5α-DHT and estradiol, are biologically important and can be formed both in the liver and in extrahepatic tissues.[151] Approximately 5 to 7% of testosterone is converted by 5α-reductase into 5α-DHT, with circulating levels of 5α-DHT about 10% of those of testosterone, and approximately 0.3% of testosterone is converted into estradiol by aromatase.[2][151][157][158] 5α-Reductase is highly expressed in the male reproductive organs (including the prostate gland, seminal vesicles, and epididymides),[159] skin, hair follicles, and brain[160] and aromatase is highly expressed in adipose tissue, bone, and the brain.[161][162] As much as 90% of testosterone is converted into 5α-DHT in so-called androgenic tissues with high 5α-reductase expression,[152] and due to the several-fold greater potency of 5α-DHT as an AR agonist relative to testosterone,[163] it has been estimated that the effects of testosterone are potentiated 2- to 3-fold in such tissues.[164]

 

Levels[edit]

Total levels of testosterone in the body are 264 to 916 ng/dL in men age 19 to 39 years,[165] while mean testosterone levels in adult men have been reported as 630 ng/dL.[166] Levels of testosterone in men decline with age.[165] In women, mean levels of total testosterone have been reported to be 32.6 ng/dL.[167][168] In women with hyperandrogenism, mean levels of total testosterone have been reported to be 62.1 ng/dL.[167][168]

Measurement[edit]

Testosterone’s bioavailable concentration is commonly determined using the Vermeulen calculation or more precisely using the modified Vermeulen method,[174][175] which considers the dimeric form of sex-hormone-binding-globulin.[176]

 

Both methods use chemical equilibrium to derive the concentration of bioavailable testosterone: in circulation testosterone has two major binding partners, albumin (weakly bound) and sex-hormone-binding-globulin (strongly bound). These methods are described in detail in the accompanying figure.

History[edit]

A testicular action was linked to circulating blood fractions – now understood to be a family of androgenic hormones – in the early work on castration and testicular transplantation in fowl by Arnold Adolph Berthold (1803–1861).[177] Research on the action of testosterone received a brief boost in 1889, when the Harvard professor Charles-Édouard Brown-Séquard (1817–1894), then in Paris, self-injected subcutaneously a "rejuvenating elixir" consisting of an extract of dog and guinea pig testicle. He reported in The Lancet that his vigor and feeling of well-being were markedly restored but the effects were transient,[178] and Brown-Séquard's hopes for the compound were dashed. Suffering the ridicule of his colleagues, he abandoned his work on the mechanisms and effects of androgens in human beings.

 

In 1927, the University of Chicago's Professor of Physiologic Chemistry, Fred C. Koch, established easy access to a large source of bovine testicles — the Chicago stockyards — and recruited students willing to endure the tedious work of extracting their isolates. In that year, Koch and his student, Lemuel McGee, derived 20 mg of a substance from a supply of 40 pounds of bovine testicles that, when administered to castrated roosters, pigs and rats, remasculinized them.[179] The group of Ernst Laqueur at the University of Amsterdam purified testosterone from bovine testicles in a similar manner in 1934, but isolation of the hormone from animal tissues in amounts permitting serious study in humans was not feasible until three European pharmaceutical giants—Schering (Berlin, Germany), Organon (Oss, Netherlands) and Ciba (Basel, Switzerland)—began full-scale steroid research and development programs in the 1930s.

  

Nobel Prize winner, Leopold Ruzicka of Ciba, a pharmaceutical industry giant that synthesized testosterone.

The Organon group in the Netherlands were the first to isolate the hormone, identified in a May 1935 paper "On Crystalline Male Hormone from Testicles (Testosterone)".[180] They named the hormone testosterone, from the stems of testicle and sterol, and the suffix of ketone. The structure was worked out by Schering's Adolf Butenandt, at the Chemisches Institut of Technical University in Gdańsk.[181][182]

 

The chemical synthesis of testosterone from cholesterol was achieved in August that year by Butenandt and Hanisch.[183] Only a week later, the Ciba group in Zurich, Leopold Ruzicka (1887–1976) and A. Wettstein, published their synthesis of testosterone.[184] These independent partial syntheses of testosterone from a cholesterol base earned both Butenandt and Ruzicka the joint 1939 Nobel Prize in Chemistry.[182][185] Testosterone was identified as 17β-hydroxyandrost-4-en-3-one (C19H28O2), a solid polycyclic alcohol with a hydroxyl group at the 17th carbon atom. This also made it obvious that additional modifications on the synthesized testosterone could be made, i.e., esterification and alkylation.

 

The partial synthesis in the 1930s of abundant, potent testosterone esters permitted the characterization of the hormone's effects, so that Kochakian and Murlin (1936) were able to show that testosterone raised nitrogen retention (a mechanism central to anabolism) in the dog, after which Allan Kenyon's group[186] was able to demonstrate both anabolic and androgenic effects of testosterone propionate in eunuchoidal men, boys, and women. The period of the early 1930s to the 1950s has been called "The Golden Age of Steroid Chemistry",[187] and work during this period progressed quickly. Research in this golden age proved that this newly synthesized compound—testosterone—or rather family of compounds (for many derivatives were developed from 1940 to 1960), was a potent multiplier of muscle, strength, and well-being.[188]

 

Other animals[edit]

Testosterone is observed in most vertebrates. Testosterone and the classical nuclear androgen receptor first appeared in gnathostomes (jawed vertebrates).[189] Agnathans (jawless vertebrates) such as lampreys do not produce testosterone but instead use androstenedione as a male sex hormone.[190] Fish make a slightly different form called 11-ketotestosterone.[191] Its counterpart in insects is ecdysone.[192] The presence of these ubiquitous steroids in a wide range of animals suggest that sex hormones have an ancient evolutionary history.[193]

Kapunda.

Six years after the founding of the colony, SA was producing almost no wheat and the government was near bankruptcy. Governor Gawler had run up huge debts that the SA Company and the British government were unwilling to pay. Governor Grey arrived to face these problems but the discovery of commercial quantities of copper at Kapunda saved the state. Captain Charles Bagot of Koonunga Station discovered the copper and conferred with Francis Dutton of Anlaby station who had also discovered copper. They kept the news secret whilst they applied for 80 acres of land to be surveyed which they then bought at auction. Thus the two purchased the Kapunda copper mine with Bagot owning 75% and Dutton 25%. The first samples were assayed and averaged 23% pure copper, an extremely high rate for any mine. Cornish miners were secured for the mining jobs and mining began in January of 1843. The first shipment of copper reached England in 1845 and the royalties from the sales revived the states flagging economy. The first group of three blocks of miners cottages owned by the mine were built in 1845 really marking the beginning of the town. They were near the Dutton chimney stack and whim. Over the next thirty five years the mine delivered about £1,000,000 of wealth and the township of Kapunda grew quickly to become a major SA town. Dutton sold his share of the mine in 1846 for a huge sum (£16,000) which allowed him to invest in the even wealthier Burra copper mine. Bagot became the major shareholder but sold out to an English company within a couple of years although he maintained financial involvement with the mine until 1859. He returned to Adelaide and built Nurney House North Adelaide. His younger son Edward lived on in the district and established a stock agent and wool handling business when the railway reached Kapunda in 1860. This business eventually merged into Elder Smiths Goldsborough Mort. Edward Bagot was an important pastoralist with several stations in the far north of SA and a boiling down works at Thebarton.

 

William Oldham became the mine superintendant in 1848, as well as the Congregational minister, the town surveyor, the local post master and a local businessman. To many he is considered the “father” of Kapunda! From 1866 Captain Osborne succeeded William Oldham as the mine superintendent until the mine closed in 1878. At first copper was carted to Port Adelaide by bullock dray, a six day journey. It was then exported to Wales for smelting. Soon the Welsh joined the Cornish in Kapunda and smelting operations began in the town in 1849. In 1851 three hundred men, including woodcutters were employed in the smelting works. The town had taken its name from an Aboriginal word “cappie oonda” which means spring. There were several mines with different names on the site.

 

In 1850 the Cornish miners built the still impressive Dutton chimney which draw the draft from the Buhl Enginehouse furnaces via a lined tunnel up into the air through the chimney stack. The Cornish traditionally built round chimney stacks and the Welsh built square chimney stacks. The Buhl pump house drew water out of the main shaft which was up to 360 feet deep. Then in 1861-62 a second winding house to haul up copper ore was built further up the hill but for some strange reason it was named the Buhl Winding house although it never contained a Buhl engine. A significant part of the Buhl Winding House ruins remain on the site. Although the first mining was simple open cut mining undertaken by miners and tributers (who were paid according to how much ore they extracted), deep shafts were soon needed to reach the underground lodes of ore. The deepest shafts sunk were 150 m (490ft) and mining operations were complex. By 1861 the mine employed 340 men and boys. Just two years later mining operations were scaled down (Moonta Mine had begun by that time) and the mine reverted to open cut mining. Low grade ore was mined until 1878, the year after the Burra mine closed. Some tribute work continued in the mine until 1912.

 

The original private township was called North Kapunda and it was laid out by the North Kapunda Mining Company in 1846 although many miners were living on the lands of the Dutton copper mine before that time. These early miners squatted on land even if they built a hut or cottage on it. In 1849 the government belatedly surveyed a town which it called Victoria and then Kapunda. Look at a map of Kapunda today and you can see this government town delineated by South, North, and West terraces. This is the northern half of today’s Kapunda where the old primary school is located. Government facilities followed soon after the founding of the mining town with the police station, now a private residence being erected in 1852. Later in 1866 the impressive Court House was built adjacent to the police station still in the private township of the Kapunda Mining Company. The early Congregational Church of 1857 was also built on land obtained from the Kapunda Mining Company. The town prospered greatly once the government railway arrived in 1860. It then became the terminus for the bullock drays carting copper ore from Burra. It was during the 1860s and 1870s that many of the fine buildings in the town were erected. At this time Kapunda was larger than Gawler and Glenelg and in 1850 Kapunda was larger than Brisbane! It was the first town in SA with gas street lighting from around 1870. Kapunda also had its own newspaper from 1864 when the Kapunda Herald was established. Andrew Thomson of Osborne House bought the newspaper later that year. The paper still operates today as the Barossa and Light Herald (from 1908) and is the largest circulating regional weekly newspaper. Thomson also ran the general store, which is now the information centre.

 

Once the mine closed in 1878 the town focused on its agricultural hinterland and Sir Sidney Kidman played a major role in developing the town. He regularly held horse and cattle auctions behind the North Kapunda Hotel in the main street and by the time of his death in 1935 he owned or had a financial interest in 68 large properties which covered over 100,000 square miles ( 64 million acres or 259,000 square kms ) of Australia. Victoria is only 227,000 square kms! Kidman donated his home to the education department in 1921 for it to become Kapunda High School- one of the first high schools outside of Adelaide. In 1876 a local Scot, Alexander Greenshields built a mansion for £4,000 which he called Lanark after his birthplace in Scotland. He was a wealthy Kapunda draper and store owner. Sir Sidney Kidman bought the house around 1897 and renamed it Eringa. A major fire destroyed the roof of Eringa in 1902 and the Art Nouveau style Marseille tile roof replaced the original roof. The western wing was also added at this time and if you get to go inside you can see the delightful Art Nouveau ceiling motifs and the leadlight windows featuring bull rushes. When Sidney and his wife Bel moved to Adelaide they purchased a house at 76 Northgate Street Unley Park which they also named Eringa. Sir Sidney Kidman died here in 1935 and was buried nearby in the Mitcham cemetery. The Kidman Empire was inherited by his son Walter and other family members. Sir Sidney Kidman was mourned by people around the world and the almost illiterate 13 year who set about to create a pastoral empire on his own died an extremely wealthy man. Kidman was knighted partly for his generosity and bequests to the Inland Mission, the Salvation Army, the Red Cross and other charities. During World War One he had also donated hundreds of horses, produce, especially beef and other materials to the Australian war effort including two fighter airplanes. As a generous employer it was not surprising that his employees put on a rodeo party for his 75th birthday in 1932 in the Adelaide Parklands. 60,000 people attended! Kidman was meant to be as comfortable talking to British royalty as to his stockmen. Although the Kidman properties are only half what they used to be in size they are for sale for round $350 million in 2015.

 

Sir Montague( or Montagu) Chapman, Third Baronet of Westmeath near Dublin Ireland, used a loop hole in the Special Survey regulations of 1839 and selected his 4,000 acres for £4,000 in different areas. He took 800 acres at Koonunga near Kapunda; 500 acres at Kapunda; 500 acres near Waterloo and Marrabel; and later in 1842 he selected a further 2,200 acres between the Little Para River and Dry Creek at what is now Mawson Lakes, Salisbury and Cross Keys. At Killua Castle in Ireland he had 9,000 acres and hundreds of tenant farmers. He wanted to do the same in SA. In 1840 he sent out Captain Charles Bagot from Ireland with his family and 224 Irish immigrants to settle his, and Bagot’s lands at Kapunda and Koonunga with Irish labourers and tenants. Then in 1842 he sailed out to SA with 120 Irish tenant farmers who he installed on his lands at Cross Keys. Sir Montague Chapman returned to Ireland the next year. Then in 1847 he sent out with a further 214 Irish immigrants to be tenant farmers on his Cross Key lands. They came out on the ships named Trafalgar and Aboukir. Sir Montague Chapman lived in Ireland not SA but returned to his SA estates in 1852 and drowned at sea in 1853 off Portland when returning to SA from Sydney. His brother Benjamin inherited the SA lands and estates. The lasting effect of Sir Montague Chapmans tenant farming ideas was a large number of Irish Catholics around the Salisbury and Kapunda districts. Many of these immigrants soon became independent landowners themselves. These early Irish Catholic’s had the fourth Catholic Church in SA built at Koonunga. But in 1862 they opened a church in Kapunda itself named St Rose of Lima which was completed in 1866. This church was replaced with the current fine red brick Romanesque style St Rose’s Church which was built in 1938. The original church was demolished in 1946. Beside the church is a bluestone church office, and behind it is a parish hall built in 1909. It replaced an earlier 1865 parish hall. Beyond that is the fine convent built in 1892. This early hall was used as a Catholic school run by the Sisters of St Joseph. When the Dominican sister took over the school they had a new two storey convent built. It is now a private residence. Imprisoned paedophile magistrate Peter Liddy owned this former convent for some years.

 

Apart from the Dutton family, Captain Bagot and Sir Sidney Kidman, Kapunda was also home to Ellen Benham (1871-1917.) She was the daughter of a Kapunda solicitor and was educated in the town. She obtained a Bachelor of Science from the University of Adelaide in 1889 and returned to Kapunda as a teacher. In 1901 she became the first female lecturer employed by the University of Adelaide, and later in 1912 she purchased her own school – Walford Grammar School for Girls. She is buried in the Kapunda cemetery. Sir Jenkin Coles a state parliamentarian who served for 33 years lived in Kapunda for most of his life. In the early days the town’s water supply came from the Light River which flows through the town. Electricity was not turned on until 1925. One of many symbols of its early growth as an urban centre was the establishment of the Kapunda Horticultural Society and Annual Show in 1857. Kapunda is 800 feet or 245 m above sea level, with a population of around 3,000 people today and it has an average annual rainfall of 500mm or 19.6 inches.

I used to google 'What is the average size?' So i could measure myself and get to it.

For years i taught myself to believe that i was the bigger one, unashamedly, realising now and looking back at past photos, i had a banging bod - then it become to little.

I look and see more of a Woman now than i ever did

Someone who has taken on a lot in the last few years

And my Body represents that, through permanent and irreplaceable marks,

My Body can fluctuate like my moods can

I have a fat day

thin day

Pretty day

Ugly day

I'm not good enough day

Today I wont eat breakfast because 'im not a breakfast person'

I am going to order the burger, chips, onion rings and 3 pints because I didnt eat anything else today, soo that counteracts it right?

Today I ate breakfast, lunch, dinner, tea, supper and had a few pints.

Whats up with that?

 

I use to google the average amount a girl like me should eat so I could fit the number.

The daily intake of calories for a Woman. 2000

The average amount of pints on a night out for me, 6

A pint averages at 340 calories

The average size of a Woman. 14

But What if I'm a 12?

Most of my friends are a 10, but I'm a 12..

The NHS has a graph that says I am a healthy 5"4 Woman when I weigh 9 stone

But Ok magazine said that i need to be 8 stone and had pictures of celebs bodies to show me my goal

 

But it could all be Lies because I have haven't weighed my self in years because I hate numbers.

 

But i still read into them.

 

At the end of the day,

I have, 2 eyes, 2 Ears, 2 legs, 2 arms, 2 bum cheeks - you get it.

 

But I also have

2 boobs,

1 vagina

and

A mouth,

And thats pretty fuckin badass to me.

I can deal with being a 4

The average woman would rather have beauty than brains, because the average man can see better than he can think. ~Author Unknown

Visby is a popular vacation destination for Scandinavians during the summer and receives thousands of tourists every year. It is by far the most populated locality outside the Swedish mainland. Visby is also the only municipality seat of Sweden that is accessible only by boat and air traffic. The University of Gotland is in Visby, and since 1 July 2013, it is a department of Uppsala University under the name Uppsala university–Campus Gotland.

I average about 6 miles a day (~12k steps) of walking while in the USA because I make a conscious effort to do so.

 

In Tokyo, I'm *easily* making 8+ miles a day just getting around via public transport.

 

Picture I took a few nights back of my Garmin Fenix3 watch showing 22k+ steps (~12mi/19km) done at that point as I was making my way from Agave to a restaurant that Chizuko was waiting for me at.

 

Surprisingly this was not a record for me (record was last year when I was in Tokyo (~24k steps).
