Designed by Robert Moog in 1970, the Minimoog Model D synthesizer is still regarded as the Rolls Royce equivalent for analog keyboard-based synthesizers. Specifically designed for touring musicians, the minimoog exported electronic music experiments from university labs out to the masses - and her deep farting bass-sounds (think of Kraftwerk's Autobahn), lead and space bleeps and sweeps have become HUGELY popular over the last 38 years.
There were originally 13,000 minimoogs produced between 1970 and 1981. After a brief hiatus during the digital-synth craze in the 1980s, the minimoog enjoyed a resurgence of interest among musicians since the 1990s...and yes, it's becoming harder to get a hold on one.
I obtained this Mini from a studio garage sale back in 1989 for US$ 150 (in prime condition - save the crackling external input knob). After lying dormant for 7 years now, it's time to bring life back into this 1973 model D mini. Tropical humidity heavily damaged the furnishing. It needs re-tuning of the oscillators, cleaning of the electronic board, new switches for filter modulation, and thinking about a new base panel.

Phonics teaches children how to decode letters in their respective sounds. This skill is essential for them to read unfamiliar words on their own. Having letter-sound knowledge allows them to link unknown words to their vocalised knowledge. Our reading class encourages students to take part in oral language activities that concentrate on concept and vocabulary development. Children hear good stories, letter recognition and spelling activities by taking part in phonics. Storytelling can be used as a method to teach ethics, values, cultural norms, differences and learning morals via different stories. It is the oldest form of teaching; it creates magic and sense of wonder; it is a unique way for kids to develop an understanding; it is also a great way to improve child’s oral fluency and help them understand concepts. Children had fun learning by sound and voice modulation done by teachers, which made it more interesting, interactive, and understandable to our little pre-schoolers. Different ways of reading activities improve reading skills like fluency, vocabulary, sentence construction, reasoning, and builds general knowledge, increases working memory and attention and allows to promote their reading skills while having fun at the same time.

The mallard or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have green heads, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.
The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.
The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). Unlike many waterfowl, mallards are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development. The non-migratory mallard interbreeds with indigenous wild ducks of closely related species through genetic pollution by producing fertile offspring. Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. This species is the main ancestor of most breeds of domestic duck, and its naturally evolved wild gene pool has been genetically polluted by the domestic and feral mallard populations.
Taxonomy and evolutionary history
The mallard was one of the many bird species originally described in the 1758 10th edition of Systema Naturae by Carl Linnaeus. He gave it two binomial names: Anas platyrhynchos and Anas boschas.The latter was generally preferred until 1906 when Einar Lönnberg established that A. platyrhynchos had priority, as it appeared on an earlier page in the text. The scientific name comes from Latin Anas, "duck" and Ancient Greek πλατυρυγχος, platyrhynchus, "broad-billed" (from πλατύς, platys, "broad" and ρυγχός, rhunkhos, "bill"). The genome of Anas platyrhynchos was sequenced in 2013.
The name mallard originally referred to any wild drake, and it is sometimes still used this way. It was derived from the Old French malart or mallart for "wild drake" although its true derivation is unclear. It may be related to, or at least influenced by, an Old High German masculine proper name Madelhart, clues lying in the alternative English forms "maudelard" and "mawdelard". Masle (male) has also been proposed as an influence.
Mallards frequently interbreed with their closest relatives in the genus Anas, such as the American black duck, and also with species more distantly related, such as the northern pintail, leading to various hybrids that may be fully fertile. The mallard has hybridized with more than 40 species in the wild, and an additional 20 species in captivity, though fertile hybrids typically have two Anas parents. Mallards and their domestic conspecifics are fully interfertile; many wild mallard populations in North America contain significant amounts of domestic mallard DNA.
Genetic analysis has shown that certain mallards appear to be closer to their Indo-Pacific relatives, while others are related to their American relatives. Mitochondrial DNA data for the D-loop sequence suggest that mallards may have evolved in the general area of Siberia. Mallard bones rather abruptly appear in food remains of ancient humans and other deposits of fossil bones in Europe, without a good candidate for a local predecessor species. The large Ice Age palaeosubspecies that made up at least the European and West Asian populations during the Pleistocene has been named Anas platyrhynchos palaeoboschas.
Mallards are differentiated in their mitochondrial DNA between North American and Eurasian populations,[19] but the nuclear genome displays a notable lack of genetic structure. Haplotypes typical of American mallard relatives and eastern spot-billed ducks can be found in mallards around the Bering Sea. The Aleutian Islands hold a population of mallards that appear to be evolving towards becoming a subspecies, as gene flow with other populations is very limited.
Also, the paucity of morphological differences between the Old World mallards and the New World mallard demonstrates the extent to which the genome is shared among them such that birds like the Chinese spot-billed duck are highly similar to the Old World mallard, and birds such as the Hawaiian duck are highly similar to the New World mallard.
The size of the mallard varies clinally; for example, birds from Greenland, though larger, have smaller bills, paler plumage, and stockier bodies than birds further south and are sometimes classified as a separate subspecies, the Greenland mallard (A. p. conboschas).
Description
The mallard is a medium-sized waterfowl species that is often slightly heavier than most other dabbling ducks. It is 50–65 cm (20–26 in) long – of which the body makes up around two-thirds – has a wingspan of 81–98 cm (32–39 in),[24]: 505 and weighs 0.7–1.6 kg (1.5–3.5 lb).[25] Among standard measurements, the wing chord is 25.7 to 30.6 cm (10.1 to 12.0 in), the bill is 4.4 to 6.1 cm (1.7 to 2.4 in), and the tarsus is 4.1 to 4.8 cm (1.6 to 1.9 in). The breeding male mallard is unmistakable, with a glossy bottle-green head and a white collar that demarcates the head from the purple-tinged brown breast, grey-brown wings, and a pale grey belly. The rear of the male is black, with white-bordered dark tail feathers. The bill of the male is a yellowish-orange tipped with black, with that of the female generally darker and ranging from black to mottled orange and brown. The female mallard is predominantly mottled, with each individual feather showing sharp contrast from buff to very dark brown, a coloration shared by most female dabbling ducks, and has buff cheeks, eyebrow, throat, and neck, with a darker crown and eye-stripe. Mallards, like other sexually-dimorphic birds, can sometimes go though spontaneous sex reversal, often caused by damaged or nonfunctioning sex organs, such as the ovaries in mallard hens. This phenomenon can cause female mallards to exhibit male plumage, and vice versa (phenotypic feminisation or masculinisation).
Both male and female mallards have distinct iridescent purple-blue speculum feathers edged with white, which are prominent in flight or at rest but temporarily shed during the annual summer moult. Upon hatching, the plumage of the duckling is yellow on the underside and face (with streaks by the eyes) and black on the back (with some yellow spots) all the way to the top and back of the head. Its legs and bill are also black. As it nears a month in age, the duckling's plumage starts becoming drab, looking more like the female, though more streaked, and its legs lose their dark grey colouring. Two months after hatching, the fledgling period has ended, and the duckling is now a juvenile. The duckling is able to fly 50–60 days after hatching. Its bill soon loses its dark grey colouring, and its sex can finally be distinguished visually by three factors: 1) the bill is yellow in males, but black and orange in females; 2) the breast feathers are reddish-brown in males, but brown in females; and 3) in males, the centre tail feather (drake feather) is curled, but in females, the centre tail feather is straight. During the final period of maturity leading up to adulthood (6–10 months of age), the plumage of female juveniles remains the same while the plumage of male juveniles gradually changes to its characteristic colours. This change in plumage also applies to adult mallard males when they transition in and out of their non-breeding eclipse plumage at the beginning and the end of the summer moulting period. The adulthood age for mallards is fourteen months, and the average life expectancy is three years, but they can live to twenty.
Several species of duck have brown-plumaged females that can be confused with the female mallard. The female gadwall (Mareca strepera) has an orange-lined bill, white belly, black and white speculum that is seen as a white square on the wings in flight, and is a smaller bird. More similar to the female mallard in North America are the American black duck (A. rubripes), which is notably darker-hued in both sexes than the mallard, and the mottled duck (A. fulvigula), which is somewhat darker than the female mallard, and with slightly different bare-part colouration and no white edge on the speculum.
Mallards are among the most common bird species to exhibit aberrant colouration, typically due to genetic mutations.[39] The female pictured here is leucistic; leucism in birds often results in 'cream-colored', 'apricot' or muted feathers on certain parts of the body.
In captivity, domestic ducks come in wild-type plumages, white, and other colours. Most of these colour variants are also known in domestic mallards not bred as livestock, but kept as pets, aviary birds, etc., where they are rare but increasing in availability.
A noisy species, the female has the deep quack stereotypically associated with ducks. Male mallards make a sound phonetically similar to that of the female, a typical quack, but it is deeper and quieter compared to that of the female. Research conducted by Middlesex University on two English mallard populations found that the vocalisations of the mallard varies depending on their environment and have something akin to a regional accent, with urban mallards in London being much louder and more vociferous compared to rural mallards in Cornwall, serving as an adaptation to persistent levels of anthropogenic noise.
When incubating a nest, or when offspring are present, females vocalise differently, making a call that sounds like a truncated version of the usual quack. This maternal vocalisation is highly attractive to their young. The repetition and frequency modulation of these quacks form the auditory basis for species identification in offspring, a process known as acoustic conspecific identification. In addition, females hiss if the nest or offspring are threatened or interfered with. When taking off, the wings of a mallard produce a characteristic faint whistling noise.
The mallard is a rare example of both Allen's Rule and Bergmann's Rule in birds. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds, as in case of the Greenland mallard which is larger than the mallards further south. Allen's Rule says that appendages like ears tend to be smaller in polar forms to minimise heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall. Examples of this rule in birds are rare as they lack external ears, but the bill of ducks is supplied with a few blood vessels to prevent heat loss, and, as in the Greenland mallard, the bill is smaller than that of birds farther south, illustrating the rule.
Due to the variability of the mallard's genetic code, which gives it its vast interbreeding capability, mutations in the genes that decide plumage colour are very common and have resulted in a wide variety of hybrids, such as Brewer's duck (mallard × gadwall, Mareca strepera).
Distribution and habitat
The mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere. It is strongly migratory in the northern parts of its breeding range, and winters farther south. For example, in North America, it winters south to the southern United States and northern Mexico, but also regularly strays into Central America and the Caribbean between September and May. A drake later named "Trevor" attracted media attention in 2018 when it turned up on the island of Niue, an atypical location for mallards.
The mallard inhabits a wide range of habitats and climates, from the Arctic tundra to subtropical regions. It is found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes and estuaries, as well as shallow inlets and open sea within sight of the coastline. Water depths of less than 0.9 metres (3.0 ft) are preferred, with birds avoiding areas more than a few metres deep. They are attracted to bodies of water with aquatic vegetation.
Behaviour
The mallard is omnivorous and very flexible in its choice of food. Its diet may vary based on several factors, including the stage of the breeding cycle, short-term variations in available food, nutrient availability, and interspecific and intraspecific competition. The majority of the mallard's diet seems to be made up of gastropods, insects (including beetles, flies, lepidopterans, dragonflies, and caddisflies), crustaceans, other arthropods, worms, many varieties of seeds and plant matter, and roots and tubers. During the breeding season, male birds were recorded to have eaten 37.6% animal matter and 62.4% plant matter, most notably the grass Echinochloa crus-galli, and nonlaying females ate 37.0% animal matter and 63.0% plant matter, while laying females ate 71.9% animal matter and only 28.1% plant matter. Plants generally make up the larger part of a bird's diet, especially during autumn migration and in the winter.
The mallard usually feeds by dabbling for plant food or grazing; there are reports of it eating frogs. However, in 2017 a flock of mallards in Romania were observed hunting small migratory birds, including grey wagtails and black redstarts, the first documented occasion they had been seen attacking and consuming large vertebrates. It usually nests on a river bank, but not always near water. It is highly gregarious outside of the breeding season and forms large flocks, which are known as "sordes".
Breeding
Mallards usually form pairs (in October and November in the Northern Hemisphere) until the female lays eggs at the start of the nesting season, which is around the beginning of spring. At this time she is left by the male who joins up with other males to await the moulting period, which begins in June (in the Northern Hemisphere). During the brief time before this, however, the males are still sexually potent and some of them either remain on standby to sire replacement clutches (for female mallards that have lost or abandoned their previous clutch) or forcibly mate with females that appear to be isolated or unattached regardless of their species and whether or not they have a brood of ducklings.
Nesting sites are typically on the ground, hidden in vegetation where the female's speckled plumage serves as effective camouflage, but female mallards have also been known to nest in hollows in trees, boathouses, roof gardens and on balconies, sometimes resulting in hatched offspring having difficulty following their parent to water.
Egg clutches number 8–13 creamy white to greenish-buff eggs free of speckles. They measure about 58 mm (2.3 in) in length and 32 mm (1.3 in) in width.[90] The eggs are laid on alternate days, and incubation begins when the clutch is almost complete. Incubation takes 27–28 days and fledging takes 50–60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch. However, filial imprinting compels them to instinctively stay near the mother, not only for warmth and protection but also to learn about and remember their habitat as well as how and where to forage for food. Though adoptions are known to occur, female mallards typically do not tolerate stray ducklings near their broods, and will violently attack and drive away any unfamiliar young, sometimes going as far as to kill them.
When ducklings mature into flight-capable juveniles, they learn about and remember their traditional migratory routes (unless they are born and raised in captivity). In New Zealand, where mallards are naturalised, the nesting season has been found to be longer, eggs and clutches are larger and nest survival is generally greater compared with mallards in their native range.
In cases where a nest or brood fails, some mallards may mate for a second time in an attempt to raise a second clutch, typically around early-to-mid summer. In addition, mallards may occasionally breed during the autumn in cases of unseasonably warm weather; one such instance of a 'late' clutch occurred in November 2011, in which a female successfully hatched and raised a clutch of eleven ducklings at the London Wetland Centre.
During the breeding season, both male and female mallards can become aggressive, driving off competitors to themselves or their mate by charging at them. Males tend to fight more than females and attack each other by repeatedly pecking at their rival's chest, ripping out feathers and even skin on rare occasions. Female mallards are also known to carry out 'inciting displays', which encourage other ducks in the flock to begin fighting. It is possible that this behaviour allows the female to evaluate the strength of potential partners.
The drakes that end up being left out after the others have paired off with mating partners sometimes target an isolated female duck, even one of a different species, and proceed to chase and peck at her until she weakens, at which point the males take turns copulating with the female. Lebret (1961) calls this behaviour "Attempted Rape Flight", and Stanley Cramp and K.E.L. Simmons (1977) speak of "rape-intent flights". Male mallards also occasionally chase other male ducks of a different species, and even each other, in the same way. In one documented case of "homosexual necrophilia", a male mallard copulated with another male he was chasing after the chased male died upon flying into a glass window. This paper was awarded an Ig Nobel Prize in 2003.
Mallards are opportunistically targeted by brood parasites, occasionally having eggs laid in their nests by redheads, ruddy ducks, lesser scaup, gadwalls, northern shovelers, northern pintails, cinnamon teal, common goldeneyes, and other mallards. These eggs are generally accepted when they resemble the eggs of the host mallard, but the hen may attempt to eject them or even abandon the nest if parasitism occurs during egg laying.
Predators and threats
In addition to human hunting, mallards of all ages (but especially young ones) and in all locations must contend with a wide diversity of predators including raptors and owls, mustelids, corvids, snakes, raccoons, opossums, skunks, turtles, large fish, felids, and canids, the last two including domestic cats and dogs. The most prolific natural predators of adult mallards are red foxes (Vulpes vulpes; which most often pick off brooding females) and the faster or larger birds of prey, (e.g. peregrine falcons, Aquila or Haliaeetus eagles). In North America, adult mallards face no fewer than 15 species of birds of prey, from northern harriers (Circus hudsonius) and short-eared owls (Asio flammeus) (both smaller than a mallard) to huge bald (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos), and about a dozen species of mammalian predators, not counting several more avian and mammalian predators who threaten eggs and nestlings.
Mallards are also preyed upon by other waterside apex predators, such as grey herons (Ardea cinerea), great blue herons (Ardea herodias) and black-crowned night herons (Nycticorax nycticorax), the European herring gull (Larus argentatus), the wels catfish (Silurus glanis), and the northern pike (Esox lucius). Crows (Corvus spp.) are also known to kill ducklings and adults on occasion. Also, mallards may be attacked by larger anseriformes such as swans (Cygnus spp.) and geese during the breeding season, and are frequently driven off by these birds over territorial disputes. Mute swans (Cygnus olor) have been known to attack or even kill mallards if they feel that the ducks pose a threat to their offspring. Common loons (Gavia inmer) are similarly territorial and aggressive towards other birds in such disputes, and will frequently drive mallards away from their territory. However, in 2019, a pair of common loons in Wisconsin were observed raising a mallard duckling for several weeks, having seemingly adopted the bird after it had been abandoned by its parents.
The predation-avoidance behaviour of sleeping with one eye open, allowing one brain hemisphere to remain aware while the other half sleeps, was first demonstrated in mallards, although it is believed to be widespread among birds in general.
Status and conservation
Since 1998, the mallard has been rated as a species of least concern on the IUCN Red List of Endangered Species. This is because it has a large range–more than 20,000,000 km2 (7,700,000 mi2) and because its population is increasing, rather than declining by 30% over ten years or three generations and thus is not warranted a vulnerable rating. Also, the population size of the mallard is very large.
Unlike many waterfowl, mallards have benefited from human alterations to the world – so much so that they are now considered an invasive species in some regions. They are a common sight in urban parks, lakes, ponds, and other human-made water features in the regions they inhabit, and are often tolerated or encouraged in human habitat due to their placid nature towards humans and their beautiful and iridescent colours. While most are not domesticated, mallards are so successful at coexisting in human regions that the main conservation risk they pose comes from the loss of genetic diversity among a region's traditional ducks once humans and mallards colonise an area. Mallards are very adaptable, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development. The release of feral mallards in areas where they are not native sometimes creates problems through interbreeding with indigenous waterfowl. These non-migratory mallards interbreed with indigenous wild ducks from local populations of closely related species through genetic pollution by producing fertile offspring. Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. The mallard itself is the ancestor of most domestic ducks, and its naturally evolved wild gene pool gets genetically polluted in turn by the domestic and feral populations. Over time, a continuum of hybrids ranging between almost typical examples of either species develop; the speciation process is beginning to reverse itself. This has created conservation concerns for relatives of the mallard, such as the Hawaiian duck, the New Zealand grey duck (A. s. superciliosa) subspecies of the Pacific black duck, the American black duck, the mottled duck, Meller's duck, the yellow-billed duck, and the Mexican duck, in the latter case even leading to a dispute as to whether these birds should be considered a species (and thus entitled to more conservation research and funding) or included in the mallard species. Ecological changes and hunting have also led to a decline of local species; for example, the New Zealand grey duck population declined drastically due to overhunting in the mid-20th century. Hybrid offspring of Hawaiian ducks seem to be less well adapted to native habitat, and using them in re-introduction projects apparently reduces success. In summary, the problems of mallards "hybridising away" relatives is more a consequence of local ducks declining than of mallards spreading; allopatric speciation and isolating behaviour have produced today's diversity of mallard-like ducks despite the fact that, in most, if not all, of these populations, hybridisation must have occurred to some extent.
Invasiveness
Mallards are causing severe "genetic pollution" to South Africa's biodiversity by breeding with endemic ducks even though the Agreement on the Conservation of African-Eurasian Migratory Waterbirds – an agreement to protect the local waterfowl populations – applies to the mallard as well as other ducks.[131] The hybrids of mallards and the yellow-billed duck are fertile, capable of producing hybrid offspring. If this continues, only hybrids occur and in the long term result in the extinction of various indigenous waterfowl. The mallard can crossbreed with 63 other species, posing a severe threat to indigenous waterfowl's genetic integrity. Mallards and their hybrids compete with indigenous birds for resources, including nest sites, roosting sites, and food.
Availability of mallards, mallard ducklings, and fertilised mallard eggs for public sale and private ownership, either as poultry or as pets, is currently legal in the United States, except for the state of Florida, which has currently banned domestic ownership of mallards. This is to prevent hybridisation with the native mottled duck.
The mallard is considered an invasive species in Australia and New Zealand, where it competes with the Pacific black duck (known as the grey duck locally in New Zealand) which was over-hunted in the past. There, and elsewhere, mallards are spreading with increasing urbanisation and hybridising with local relatives.
The eastern or Chinese spot-billed duck is currently introgressing into the mallard populations of the Primorsky Krai, possibly due to habitat changes from global warming. The Mariana mallard was a resident allopatric population – in most respects a good species – apparently initially derived from mallard-Pacific black duck hybrids; it became extinct in the late 20th century.
The Laysan duck is an insular relative of the mallard, with a very small and fluctuating population. Mallards sometimes arrive on its island home during migration, and can be expected to occasionally have remained and hybridised with Laysan ducks as long as these species have existed. However, these hybrids are less well adapted to the peculiar ecological conditions of Laysan Island than the local ducks, and thus have lower fitness. Laysan ducks were found throughout the Hawaiian archipelago before 400 AD, after which they suffered a rapid decline during the Polynesian colonisation.Now, their range includes only Laysan Island. It is one of the successfully translocated birds, after having become nearly extinct in the early 20th century.
Relationship with humans
Mallards have often been ubiquitous in their regions among the ponds, rivers, and streams of human parks, farms, and other human-made waterways – even to the point of visiting water features in human courtyards.
George Hetzel, mallard still life painting, 1883–1884
Mallards have had a long relationship with humans. Almost all domestic duck breeds derive from the mallard, with the exception of a few Muscovy breeds, and are listed under the trinomial name A. p. domesticus. Mallards are generally monogamous while domestic ducks are mostly polygamous. Domestic ducks have no territorial behaviour and are less aggressive than mallards. Domestic ducks are mostly kept for meat; their eggs are also eaten, and have a strong flavour. They were first domesticated in Southeast Asia at least 4,000 years ago, during the Neolithic Age, and were also farmed by the Romans in Europe, and the Malays in Asia. As the domestic duck and the mallard are the same species as each other, it is common for mallards to mate with domestic ducks and produce hybrid offspring that are fully fertile. Because of this, mallards have been found to be contaminated with the genes of the domestic duck.
While the keeping of domestic breeds is more popular, pure-bred mallards are sometimes kept for eggs and meat, although they may require wing clipping to restrict flying.
Hunting
Mallards are one of the most common varieties of ducks hunted as a sport due to the large population size. The ideal location for hunting mallards is considered to be where the water level is somewhat shallow where the birds can be found foraging for food. Hunting mallards might cause the population to decline in some places, at some times, and with some populations. In certain countries, the mallard may be legally shot but is protected under national acts and policies. For example, in the United Kingdom, the mallard is protected under the Wildlife and Countryside Act 1981, which restricts certain hunting methods or taking or killing mallards.
As food
Since ancient times, the mallard has been eaten as food. The wild mallard was eaten in Neolithic Greece. Usually, only the breast and thigh meat is eaten. It does not need to be hung before preparation, and is often braised or roasted, sometimes flavoured with bitter orange or with port.

Description of work: Renaissance Hotels tasked architect Jose R. Marchand and interior designer Jorge Rossello with renovating and saving this beachside landmark. "[B]y the mid-1990s the venerable La Concha hotel had been shuttered, abandoned and left to rot...Originally designed by Osvaldo Toro and Miguel Ferrer, with an eccentric but utterly loveable seashell-shaped restaurant by Mario Salvatori [sic], La Concha was a beautifully massed, expertly sited, vividly inventive building perfectly in sync with its time. Closely attuning the hotel to its sun-swept setting, the architects created deep-shading overhangs, open corridors, windows and doors that gave onto lush interior courtyards and provided cross ventilation, and beautifully lacy quiebra-sol (their take on a brise-soleil) for further modulation of the light and heat" (Frank, Michael. "La Concha Revival". Architectural Digest. Aug 2009, p. 103-104. Print).

Sneak in a discussion topic! - (This is a fake add, for you caption readers). I want to tell you about an exciting new technology I just came across this morning and had to put in this presentation. Virtual Worlds are growing in interest, but for those involved, you know that the requirements of high end PCs and fast networks are limiting factors. Skyworlds is going to change all of that. Through a revolutionary development in fractal frequency modulation and S2 scalable data store housing, you will be able to move seamlessly between virtial worlds on a PC and on any mobile device.
Okay- let’s say this has just come across your attention screen. How to do react to a new technology? What do you do? What is your approach?

Pelavin Gallery is proud to announce a solo exhibition of recent work by American artist, Kate Beck. This show will include large scale poured oil paintings and graphite drawings on aluminum panel. This will be Beck’s first solo exhibition at the gallery, and in New York City.
In this new body of work, Beck continues her engagement with repetitive tonal rendering as a means of interaction between light and shadow, human thought and consciousness, and the dynamic architectonics of space. This time she takes the essence of form further by using aluminum substrates, allowing modulating marks of graphite and poured oil to accumulate and shift amidst the confines of the geometric shapes. Tension oscillates between formalistic geometry and existential space; an allusion to thought and consciousness, and the passage of time.

Shifting Paradigms from Mass Production to Mass Customization
Computational architecture and design course
Conventional construction methods all depart from the basic premises of mass production: standardization, modulation and a production line. What these systems developed during the last two centuries fail to take into account are the evolutionary leaps and bounds the manufacturing industry has taken over the last decades. With the introduction of CNC technologies and rapid prototyping machines have altered the paradigms of fabrication forever. It is due to these new tools that it is now possible to create (n) amount of completely unique and different pieces with the same amount of energy and material that is required to create (n) identical pieces. The possibilities for implementation of new forms, textures, materials and languages are infinite due to the versatility that these new tools offer a growing network of architects, designers, fabricators that are integrating them into their professional practices to generate unique and precise objects that respond to countless data and real-life conditions.

The Palatine Chapel, is the royal chapel of the Norman kings of Sicily situated on the first floor at the center of the Palazzo Reale in Palermo, southern Italy.
Commissioned by Roger II of Sicily in 1132 and built upon an older chapel (now the crypt) constructed around 1080.
The mosaics being only partially finished by 1143.
The sanctuary, dedicated to Saint Peter, is reminiscent of a domed basilica. It has three apses, as is usual in Byzantine architecture, with six pointed arches (three on each side of the central nave) resting on recycled classical columns.
The mosaics of the Palatine Chapel are of unparalleled elegance as concerns elongated proportions and streaming draperies of figures. They are also noted for subtle modulations of colour and luminance. The oldest are probably those covering the ceiling, the drum, and the dome. The shimmering mosaics of the transept, presumably dating from the 1140s and attributed to Byzantine artists, with an illustrated scene, along the north wall, of St. John in the desert and a landscape of Agnus Dei.
Below this are five saints, the Greek fathers of the church, St. Gregory of Nissa, St. Gregory the Theologian, St. Basil, St. John Chrysostom and St. Nicholas.
The three central figures, St. Gregory, St. Basil, St. John Chrysostom, allude to the Orthodox cult known as the Three Hierarchs, which originated fifty years earlier.
Roger II of Sicily depicted on the muqarnas ceiling in an Arabic style.
The rest of the mosaics, dated to the 1160s or the 1170s, is executed in a cruder manner and feature Latin (rather than Greek) inscriptions. Probably a work of local craftsmen, these pieces are more narrative and illustrative than transcendental.
The chapel combines harmoniously a variety of styles: the Norman architecture and door decor, the Arabic arches and script adorning the roof, the Byzantine dome and mosaics. For instance, clusters of four eight-pointed stars, typical for Muslim design, are arranged on the ceiling so as to form a Christian cross.
Muqarnas ceiling
The hundreds of facets were painted, notably with many purely ornamental vegetal and zoomorphic designs but also with scenes of daily life and many subjects that have not yet been explained. Stylistically influenced by Iraqi 'Abbasid art, these paintings are innovative in their more spatially aware representation of personages and of animals.
The chapel has been considered a union of a Byzantine church sanctuary and a Western basilica nave.
The sanctuary, is of an "Eastern" artistic nature, while the nave reflects "Western" influences.
Nave
The nave, constructed under Roger II, did not contain any Christian images.
These were added later by Roger II's successors, William I and William II.
The nave's ceiling consists of Greek, Latin and inscriptions.
The frame for the royal throne sets against the west wall of the nave.
There are six steps leading up to where the throne would be, along with two heraldic lions in two roundels upon the spandrels over the throne frame gabel.
Sanctuary
As an expression of Norman culture, St. Dionysius and St. Martin are represented in the sanctuary.
Mosaics are of Byzantine culture in their composition and subjects.
The apex of the dome consists of the Pantokrator, with rows of angels, prophets, evangelists and saints.
The Byzantine motif ends abruptly with scenes from Christ's life along the south wall of the southern transept arm, while the north wall consists of warrior saints

ASYNCHRONOUS WIRELESS DATA LINK
There are some situations where the data from different sensors is to be monitored and transmitted to monitoring device or a PC. While at some environments the wire
can not be run from the sensor to the monitoring device. In these situations wireless transmissions would be more beneficial. Most of the sensor units need a less amount of data furthermore, transmitted baud rate required is also slow. Since this seems to be a simple data link the efficient alternative is ‘WIRELESS ASYNCHRONOUS DATA LINK’(LOW SPEED). Not only the above industrial application but also the same idea can be implemented for point to point connection of computers in a
workplace or building. This project is expected to yield a Schmart PCB module; which would find applications in many areas. The goal of the project design is simple and easy to implement. Asynchronous
communication and RS232,--- ; since RS232 Interface is widely used and easily compatible /programmable with data terminal equipment, it’s been chosen the RS232 interface for the serial communication of data between DTE and DCE. The signals emanating from the RS232 have been conditioned by Encoder; Then after it needs to be fed to the UHF Transmitter on a single chip. Transmitter employs ASK Modulation and the frequency for transmission is 433.92MHz.
This is being tested using a 1kV anode voltage instead of the 8kV on the datasheet. The filament voltage is regulated at 1V with a 3.3Ω series resistor. Modulation voltage is 12V. Acceleration (55v) and Focus (31-55v) are approximately in proportion with the original ratios.

A pair of free-form volumes responds to the landscape qualities of the site – a former floodplain of the Rhine – as well as to the memory of villas in park-like settings that once occupied this now increasingly densified area. In addition the new buildings acknowledge the sculptural characteristics of the adjacent twelve-storey 1960s high-rise, while their vivid polychromy supports the organic character of the external space.
In each building the office areas are arranged around three compact cores. Primary cores are connected to the main entrance hall, while secondary ones are entered from the more intimate patio spaces. Every floor can be subdivided into three distinct units, each identifiable through its own reception area, sculptural stair and elevator core. The varying depth of plan offers a great number of variations in office layout. The generosity of the windows is echoed in the glazed corridor walls that ensure maximum light throughout the depth of the plan, while giving spectacular views out towards the Rhine and Cologne Cathedral.
One innovative development lies in the series of finger-shaped canopies that were prototyped as an alternative to a suspended ceiling, so as to take advantage of thermal mass and to increase clear height. All necessary services – lighting, air distribution, sprinklers and acoustic modulation – are unobtrusively integrated in these overhead elements. The offices use groundwater from the Rhine as a source of geothermal energy and to supplement the heating and cooling systems, while also carefully building above the 100-year water level and to flood defence specifications.
This my version of the Tellun Neural Agonizer, a maxed out version of a reverb unit. It drives and controls 2 reverb tanks, and adds quite a few controls and alternative modulations to the mix. The front panel is from the Bridechamber.
Airbrushed various Alclads onto the tripod after polishing the helmet (hohoho).
I thought I'd try colour modulation for the first time on the tanks. Looks crazy now but it should tone down nicely.

The Minilogue. There's still a couple of knobs I haven't got the hang of yet. Cross-modulation depth? Ring modulation?
So I moulded and casted an improved cockpit from my vac-formed master, cleaned it up, and hey, not bad!
All credit for the electronics and programming work goes to my dad, who is just roughing out the sequencing for the micropython system. He assures me the modulation and frequency can be made a lot smoother, but these tests are just to understand what we're trying to acheive
We produce this model as “Pick-up Activator” FET design preamp for bass guitar, under “Alen Geere”, our other brand. This is electric guitar version that boost the signal +5dB at maximum volume level. It has improved tone control and a switch for boost/cut between 200-800 Hz of frequencies. This option bring all humbucker-loaded guitars to standard “Tele” side an incredible way. High input and low output impedances are ideal for driving long cables. It’s also suitable with bass.
