en.wikipedia.org/wiki/Spring_(season)
Definition
Meteorologists generally define four seasons in many climatic areas, winter, spring, summer and autumn (or fall). These are demarcated by the values of their average temperatures on a monthly basis, with each season lasting three months. The three warmest months are by definition summer, the three coldest months are winter, and the intervening gaps are spring and autumn. Spring, when defined in this manner, can start on different dates in different regions. In most of Northern Hemisphere locations, spring occurs during the months of March, April and May[1]. (Summer is June, July, August; Autumn is September, October, November; Winter is December, January, February.) The vast majority of Southern Hemisphere locations will have opposing seasons with spring in September, October and November.[2]
Astronomically, the vernal equinox (usually 20 March in the Northern Hemisphere, and 22 September in the Southern Hemisphere), should be the middle of spring (based on the angle of the sun and insolation) and the summer solstice (usually 21 June in the Northern Hemisphere and 21 December in the Southern Hemisphere) should be mid-summer (because the sun is at its highest) but daytime temperatures lag behind insolation by several weeks because the earth and sea have thermal latency and take time to warm up.
Some cultures, such as those who devised the Celtic and East Asian calendars, call the spring equinox mid-spring, but others (especially in the USA and sometimes in England) regard it as the "first day of spring". For most temperate regions, signs of spring appear long before the middle of March, but the folklore of 21 March being the "first day of spring" persists, and 21 June as the "first day of summer" is common in the USA. In South Africa, Australia and New Zealand, spring begins on 1 September, and has no relation to the vernal equinox.[3]
In East Asian Solar term, spring begins on 4 February and ends on 5 May. Similarly, according to the Celtic tradition, which is based solely on daylight and the strength of the noon sun, spring begins in early February (near Imbolc or Candlemas) and continues until early May (Beltane).
The phenological definition of spring relates to indicators, the blossoming of a range of plant species, and the activities of animals, or the special smell of soil that has reached the temperature for micro flora to flourish. It therefore varies according to the climate and according to the specific weather of a particular year.
Events
In spring, the axis of the Earth is increasing its tilt toward the Sun and the length of daylight rapidly increases for the relevant hemisphere. The hemisphere begins to warm significantly causing new plant growth to "spring forth," giving the season its name. Snow, if a normal part of winter, begins to melt, and streams swell with runoff. Frosts, if a normal part of winter, become less severe. Temperate climates have no snow and rare frosts, the air and ground temperature increases more rapidly. Many flowering plants bloom this time of year, in a long succession sometimes beginning even if snow is still on the ground, continuing into early summer. In normally snowless areas "spring" may begin as early as February (Northern Hemisphere) heralded by the blooming of deciduous magnolias, cherries, and quince, or August (Southern Hemisphere) in the same way. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, or monsoonal, or cyclonic. Often the cultures have locally defined names for seasons which have little equivalence to the terms originating in Europe. Many temperate areas have a dry spring, and wet autumn (fall), which brings about flowering in this season more consistent with the need for water as well as warmth. Subarctic areas may not experience "spring" at all until May or even June, or December in the outer Antarctic.
While spring is a result of the warmth caused by the turning of the Earth's axis, the weather in many parts of the world is overlain by events which appear very erratic taken on a year-to-year basis. The rainfall in spring (or any season) follows trends more related to longer cycles or events created by ocean currents and ocean temperatures. Good and well-researched examples are the El Niño effect and the Southern Oscillation Index.
Unstable weather may more often occur during spring, when warm air begins on occasions to invade from lower latitudes, while cold air is still pushing on occasions from the Polar regions. Flooding is also most common in and near mountainous areas during this time of year because of snowmelt, accelerated by warm rains. In the United States, Tornado Alley is most active this time of year, especially since the Rocky Mountains prevent the surging hot and cold air masses from spreading eastward and instead force them into direct conflict. Besides tornadoes, supercell thunderstorms can also produce dangerously large hail and very high winds, for which a severe thunderstorm warning or tornado warning is usually issued. Even more so than in winter, the jet streams play an important role in unstable and severe weather in the springtime in the Northern Hemisphere.
In recent decades season creep has been observed, which means that many phenological signs of spring are occurring earlier in many regions by a couple of days per decade.
Spring is seen as a time of growth, renewal, of new life (both plant and animal) being born. The term is also used more generally as a metaphor for the start of better times, as in the Prague Spring. Spring in the Southern Hemisphere is different in several significant ways to that of the Northern Hemisphere. This is because: there is no land bridge between Southern Hemisphere countries and the Antarctic zone capable of bringing in cold air without the temperature-mitigating effects of extensive tracts of water; the vastly greater amount of ocean in the Southern Hemisphere at all latitudes; at this time in Earth's geologic history the Earth has an orbit which brings it in closer to the Southern Hemisphere for its warmer seasons; there is a circumpolar flow of air (the roaring 40s and 50s) uninterrupted by large land masses; no equivalent jet streams; and the peculiarities of the reversing ocean currents in the Pacific.

Two one hour twisted yet comic explorations looking at the darker side of human nature with a short interval between. We all recognise love, we all understand hate and yet we dance between them day-by-day. How far do those emotions take us and can they push us across lines we should never have crossed? The first, Little One by Hannah Moscovitch is the haunting story of adopted siblings Aaron and Claire - one the definition of normal, the other deeply disturbed and unpredictable - and the strange lives of their neighbours, a man and his mail order bride. The second is Eye Spy, a company devised piece: A cycle of six short plays that take a peek at the not so distant future. Eye Spy is set in a Tech-obsessed society and looks at the stories of people living under the 'BOOK' regime. Sarah, a modern influencer needs more followers, how far will she go to get them? Jack has started wearing his yellow hat with pride, why? Will we ever find the Hacker? Whatever you do DON'T type a FORBIDDEN WORD!

Rational numbers definition Numbers appear like dancing letters to many students as they are not able to distinguish between different categories of numbers and get confused in understanding their concepts. Number family has numerous of siblings and one of them is irrational and Rational Numbers. You can define rational number as a nameable number, as we can name it in the whole numbers, fractions and mixed numbers. On the other side irrational number is one that can’t be expressed in simple fraction form. With the help of real life examples you can easily distinguish between different types of numbers.

Graptolites of the Cincinnatian
Presented by: Rich Fuchs (Dry Dredgers, Cincinnati, Ohio, USA)
21 November 1997 & 28 May 2010
----------
Cincinnatian Series Graptolites:
Geniculograptus is the most common graptolites in the Cincinnatian Series (type Upper Ordovician of North America; outcrop belt in & around Cincinnati, Ohio).
(strata.uga.edu/cincy/fauna/graptolithina/DGGeniculograptu...)
(www.flickr.com/photos/jsjgeology/16771115263)
(www.flickr.com/photos/jsjgeology/17203716088)
The Cincinnatian has biserial and uniserial graptoloid graptolites - uniserial forms are not common, while biserial forms are ~common.
James Hall probably was the first to identify Cincinnatian graptolites. Ruedemann named many Cincinnatian species. John Taylor's 1974 University of Cincinnati Master's thesis was about Cincinnatian graptolites - it has some omissions. One problem is tracing original type specimens. Charles Mitchell & Stig Bergström have revised some Cincinnatian graptolites.
Most Cincinnatian forms have had genus reassignments based on modern genus definitions, which are based on sicula structure (the first theca). Graptolite systematics focuses on the proximal end of the skeleton and how thecae begin to bud off.
The nema is attached to the seafloor or something floating in the water or to a float.
Rich Fuchs hasn’t found nemas attached to floats, probably because they got detached. Rich did find a possible float once. Floats are not found because they float away. Graptolites are worldwide.
Dictyonema was a little bush. (www.flickr.com/photos/jsjgeology/15126818037) It’s now shown upside down (attached to floats & hung down, it’s now thought).
Cincinnatian graptolites are usually simple blades.
Tetragraptus from Australia was pendant with 4 stipes.
(www.geo-tools.com/Images/Gallery/Fossil/Big/036.jpg)
Some graptolites were coiled, like the monograptid Spirograptus (Australia; Lower Ordovician of New York).
(www.graptolit.com/spirograptus.png-for-web.jpg)
Many graptolites were floaters - they did get distributed very widely. Graptolites are used for relative dating & correlation.
Ordovician and Silurian rocks are divided into graptolite biozones. The end-Ordovician experienced an Ice Age - all but 1 or 2 genera of graptolite went extinct. Every post-Ordovician graptolite is related to these 1 or 2 genera. All graptolites went extinct in the mid-Mississippian. They may be alive in the present day, though.
There are 7 orders of graptolites.
Dendroidea - sessile, attached; bush-like; have the longest duration of any graptolite group - Middle Cambrian to Middle Mississippian.
Graptoloidea - planktonic (floaters), attached to a float structure; only Ordovician to Silurian.
Dendroids and graptoloids are found in Cincinnatian rocks.
Graptolites like deep water - they are found in shales. They are very fragile. Shale tends to flake as it ages, so that combination means good graptolites are difficult to find.
Sometimes, graptolites are found on limestone - get better preservation.
The Kope Formation (Edenian Stage, lower Cincinnatian Series, Upper Ordovician) has the best Cincinnatian graptolites. There are 16 genera total in the Cincinnatian, not counting the Utica Shale (Middle Ordovician or Upper Ordovician, depending on who you ask). Same for the Fulton Shale.
There are 31 species of graptolites in the Cincinnatian (Upper Ordovician of the Cincinnati, Ohio area): 9 graptoloid graptolites (Kope Formation to Waynesville Formation), 7 dendroid graptolites (including problematic forms) (Kope Formation to Waynesville Formation), 5 encrusters (Kope Formation to Whitewater Formation), plus other problematic species.
Dendroidea
Dictyonema arbusculum - Cincinnatian, Kope Formation; rare; Rich Fuchs hasn’t found one yet; it resembles Dictyonema flabelliforme.
Acanthograptus ulrichi - a dendroid like Dictyonema arbusculum, except that it’s in the Fairview Formation. Rich hasn’t seen it or found one. Acanthograptus ulrichi is bush-like but with thorns.
(digimuse.nmns.edu.tw/DigiMuse/XML/files/000001/80/27/6f/0...)
Graptoloidea
The Cincinnatian Series has scandent, reclined, and reflexed forms - these are prevalent in the Upper Ordovician. Pendant, declined, and deflexed forms tend to be Lower Ordovician. So, there’s change through time.
Geniculograptus typicalis typicalis (strata.uga.edu/cincy/fauna/graptolithina/DGGeniculograptu...) (www.flickr.com/photos/jsjgeology/16771115263) (www.flickr.com/photos/jsjgeology/17203716088)
The first identified Cincinnatian graptolite, the most common, and most well studied Cincinnatian graptolite is the graptoloid Geniculograptus typicalis typicalis (there are other subspecies) - it’s common in the Southgate Member of the Kope Formation; it's upper range is not really known, but it goes down into the Middle Ordovician. James Hall’s 1800s list of New York graptolites listed Climacograptus typicalis but no description accompanied the name. Hall named it and figured it. This was the first reference to that graptolite. Ruedemann’s description gave species credit to Hall, though he never originally described Climacograptus typicalis. Ruedemann claims he described it in 1908. James apparently described it in 1892. This species is biserial. Riva recognized that typicalis isn't a Climacograptus. Mitchell, using sicular morphology, put typicalis in Geniculograptus - it is no longer in Climacograptus. Riva also proposed a new genus name (Uticagraptus), but that name was published one month after Mitchell's new genus name. In northern Kentucky, troughs/trough fillings of Geniculograptus have been found with the graptolites all lined up (Ron Fine has found these). Geniculograptus typicalis typicalis is 2 to 5 centimeters long (3/4 inch to 2 inches). Its thecae have a slightly tapering square appearance. These alternate on either side of the virgula.
Geniculograptus typicalis magnificus is a big biserial form in the Maysville Stage. typicalis typicalis has lengths up to 3.5 centimeters (1 3/8 inches), but typicalis magnificus can get to 7 centimeters long (almost 3 inches). It looks like it has smaller thecae, but they are just spread out more, because the rhabdosome is wider between thecae.
Geniculograptus typicalis posterus is a smaller-than-magnificus form in the Fairview Formation.
Geniculograptus pygmaeus is also a now-well studied form. (www.flickr.com/photos/jsjgeology/17389529022) It has been tossed around from time to time as typicalis. It can be confused with typicalis, but it’s a lot smaller than typicalis. pygmaeus is younger - it occurs in the upper Kope Formation and the lower Fairview Formation. pygmaeus and typicalis do overlap, but pygmaeus is younger & typicalis is older. Geniculograptus pygmaeus is usually less than 1 centimeter long and ~1 millimeter or so wide (this species is small & narrow). Geniculograptus typicalis is ~1.25 inches (2 to 3 centimeters) long. Geniculograptus pygmaeus has square thecae that taper more than in Geniculograptus typicalis.
An intermediate form between G. typicalis typicalis and G. pygmaeus is known - it occurs in the top of the Southgate Member of the Kope Formation in Kentucky - it’s not named yet, apparently - Geniculograptus sp. - it is longer and skinnier than pygmaeus, but still smaller than typicalis.
Orthograptus quadrimucronatus - short spines come out from the sides; found in the Kope Formation to Arnheim Formation (the Richmondian Stage form is a subspecies - O. quadrimucronatus richmondensis). Biserial; thecae are more triangular and have thecal spines; the thecae are chevron-shaped (V-shaped), while Geniculograptus, in contrast, has squarish thecae. This is a larger species than Arnheimograptus anacanthus.
(Orthograptus - www.geodil.com/images/30/3004/mid.jpg)
Arnheimograptus anacanthus - found at the Flat Run Trilobite Lagerstätte site near Mt. Orab, Ohio (look for graptolites there, not trilobites!). This is a relatively new genus (named by Mitchell); it is only ~1 centimeter long, with chevron-shaped thecae; biserial.
Dicranograptus nicholsoni (strata.uga.edu/cincy/fauna/graptolithina/DicranograptusNi...) - Rich Fuchs has never seen it; a reclined graptolite - has a scandent portion, then it splits; it has a two-stipe rhabdosome with a biserial extension (Y-shaped rhabdosome - the root is biserial; the two upper branches are uniserial). Occurs in the bottom of the Kope Formation (Fulton Shale Member), which is mostly flooded now by the Ohio River.
Dicellograptus forchammeri (strata.uga.edu/cincy/fauna/graptolithina/DicellograptusFo...) - a uniserial grapolite supposedly in the Fairveiw Formation; formerly Leptograptus annectens (a Ruedemann name). Mitchell and Bergström reassigned it to Dicellograptus, because Leptograptus has a two-stipe rhabdosome. The Cincinnatian form is actually Dicellograptus sp. aff. Dicellograptus forchammeri. It has a V-shaped or U-shaped rhabdosome.
Amplexograptus maxwelli (www.flickr.com/photos/jsjgeology/17203906150) - occurs in the bottom of the Kope Formation, in the Fulton Shale; it is similar to Geniculograptus typicalis posterus, but don't worry - it occurs in beds below water level along the Ohio River in Cincinnati; biserial; square thecae - slightly rounded lip of thecae; tip is different from Geniculograptus.
(Amplexograptus - jpaleontol.geoscienceworld.org/content/76/5/921/F2.large.jpg)
Climacograptus - there’s still one of these in the Fairview Fm.
Uncertain placement graptolites:
Most of what's been assigned to the Cincinnatian dendroid graptolites is Mastigograptus, but there's lots of conjecture about what it is. There are five or so species of Mastigograptus in the Cincinnatian Series. They appear as plain, black lines (flattened tubes) in rock - "pepper rock". The five species range from the Kope Formation to the Waynesville Formation. The best way to figure out the species is to use the stratigraphic horizon.
Mastigograptus tenuiramosus - delicate; occurs in the bottom half of the Kope Formation; usually fragile - forms pepper rock. Pepper rock usually has scolecodonts. Branch angles are at 45°.
Mastigograptus gracillimus (strata.uga.edu/cincy/fauna/graptolithina/MastigograptusGr...) - these are decent-sized fossils compared with Cincinnatian graptoloids; Kope Formation to Fairview Formation.
Mastigograptus perixilis - Waynesville Formation.
(www.flickr.com/photos/jsjgeology/17203569048)
Mastigograptus strictus - has shallow branching angles. Occurs in the Arnheim Formation - can be found at the Flat Run Trilobite Lagerstätte site near Mt. Orab, Ohio. But, it could be the same species as Mastigograptus tenuiramosus.
Mastigograptus multifasciatus - upper Fairview Formation.
Are there visible thecae in Mastigograptus? Ruedemann said thecae in Mastigograptus are known from other areas. Taylor found only one thecae-bearing specimen. Rich has never seen thecae in Cincinnatian Mastigograptus. The Treatise has thecae drawn in on the Mastigograptus illustration.
Mastigograptus is sometimes listed as a dendroid, sometimes listed as uncertain.
Bulman didn’t know where to place Mastigograptus within the graptolites.
Ultrastructure studies show Mastigograptus is a graptolite. But some say they look like seawhips.
Rich Fuchs thinks that Mastigograptus is similar to seawhips. He thinks it is almost definitely not a graptolite. Seawhips are a form of coral (horny coral). After seawhips die, the outer organic material comes off, resulting in a Mastigograptus-like thing.
[Dave Meyer comment: seawhips now are much larger than Mastigograptus, but the point is well taken. There’s nothing saying Ordovician seawhips couldn’t have been small enough to be Mastigograptus.]
Urbanek did an SEM study of Mastigograptus - it’s structure is consistent with graptolites; the chemistry is the same as graptolites; therefore, it could be a graptolite; but, it still could be something else. There’s still no evidence of thecae.
There are 5 or 6 species of Cincinnatian Chaunograptus named. Most are Liberty Formation forms. Most are based on one specimen. Most of the holotypes are now missing (museum-wise). The Smithsonian renumbered their collections a while ago and lost the Chaunograptus. One was lost in a Dayton flood. Few holotypes are left. Chaunograptus are extremely fragile - not often found.
Chaunograptus is an encruster that may not be a graptolite. It is fairly rare and easily overlooked. It is more like to be found in the Richmondian Stage, especially encrusting brachiopod shells. Chaunograptus is classified as a dendroid or uncertain. There are several species, but some don't look like the rest. Ruedemann listed 11 species - 7 were Upper Ordovician - 6 were Cincinnatian. Now we're down to five species. John Taylor said two of them were synonymous. Taylor's thesis says that Chaunograptus shideleri is the same as Chaunograptus delicatus. Most of the species are Richmondian. Chaunograptus fossils have been found at the Newport Shopping Center. Rich Fuchs has found what he calls Chaunograptus contortus and Chaunograptus delicatus in the Kope Formation. This is probably a form whose ranges are not well known.
Chaunograptus contortus - encrusting black spots on nodules. Twisted thecae with extremely thin lines (nemas). Rich Fuchs has found Chaunograptus contortus in the Kope Formation, but it was described from the Liberty Formation. The type is missing - couldn't be found by Taylor.
(www.flickr.com/photos/jsjgeology/17203753020)
(www.flickr.com/photos/jsjgeology/17389341202)
Chaunograptus delicatus - the type specimen is encrusting a nodule; it has thicker lines than C. contortus; the lines trail around; occasional thecae structures; the lines move out from a central point. Also first described from the Liberty Formation. Occurs in the Liberty Formation and Whitewater Formation. The type specimen is known.
(www.flickr.com/photos/jsjgeology/16771017233)
(www.flickr.com/photos/jsjgeology/16771013283)
Chaunograptus vermiformis - Liberty Formation. The type specimen is in the Smithsonian - it's been renumbered, but it has been found.
Chaunograptus macrothecae - Grant Lake Formation. Type specimen can't be found.
Chaunograptus gemmatus - Kope Formation The type specimen (one specimen) is known.
Inocaulis (www.graptolite.net/INOCAUL.jpg) (www.flickr.com/photos/jsjgeology/17203749888) - a worse genus than Mastigograptus in terms of identifying structure and determining affinities. This is a rare fossil that's supposedly a graptolite. Inocaulis is a non-descript collection of tubes, forming a stem - looks like a series of tubes (= the thecae) bundled together. Two Cincinnatian species - Inocaulis simplex (Kope Formation) and Inocaulis grandis (Maysville Stage); it doesn’t look like a graptolite, but it’s listed as a dendroid. Grammaria is a modern hydrozoan (chess.myspecies.info/sites/chess.myspecies.info/files/gra...) - it has a similar arrangement of tubes put together. Inocaulis may be another graptolite that really isn’t.

natural numbers definition Natural numbers include numbers like 1, 2, 3, 4, 5...... Hence, they are also called as Counting Numbers. The smallest Natural Number is 1 but the greatest Natural Number is not defined. So the greatest Natural Number can be written as 0 . Thus the concept of natural Numbers gives the basic and primitive notion of infinity which makes it so important in Mathematics. Apart from counting, Natural Numbers are also used to represent the order or position of elements.

Definition of Biometrics Biometrics literally means life measurement and is associated with utilization of distinctive physiological characteristics for identifying individuals. Though most important application related with biometrics is that of security, it is used as the computer interface too. A range of Biometric applications are being used for authenticating person’s identity. With the use of various features including fingerprints, face, signature, and iris, a person is identified.
