This muscle is commonly attributed to the stabilization of flight in other birds; however, the absence of this deep layer causes this mode of "flapping flight" is simply a mechanism that it shares with other ground birds in order to escape predators. However, they would rather prefer to simply run away and hide from their predators rather than to fly. If startled, they can suddenly burst upwards at great speed and with a distinctive wing sound.Golden pheasants lay 8 to 12 eggs at a time and will then incubate these for around 22–23 days.

Reflecting telescope. A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors. Reflecting telescopes come in many design variations and may.

Reflecting telescope. employ extra optical elements to improve image quality or place the image in a mechanically advantageous position. Since reflecting telescopes use mirrors, the design is sometimes referred to as a catoptric telescope.From the time of Newton to the 1800s, the mirror itself was made of metal usually speculum metal. This type included Newton's first designs and even the largest telescopes of the 19th century, the Leviathan of Parsonstown with a 1.8 meter wide metal mirror. In the 19th century a new method using a block of glass coated with very thin layer of silver began to become more popular by.

Reflecting telescope. his telescope and five years before Hooke built the first such Gregorian telescope, Isaac Newton in 1668 built his own reflecting telescope, which is generally acknowledged as the first reflecting telescope. It used a spherically ground metal primary mirror and a small diagonal mirror in an optical configuration that has come to be known as the Newtonian telescope.Despite the theoretical advantages of the reflector design, the difficulty of construction and the poor performance of the speculum metal mirrors being used at the time meant it took over 100 years for them to become popular. Many of the advances in reflecting.

Reflecting telescope. useful for terrestrial observations. Some small spotting scopes are still built this way. There are several large modern telescopes that use a Gregorian configuration such as the Vatican Advanced Technology Telescope, the Magellan telescopes, the Large Binocular Telescope, and the Giant Magellan Telescope.## Newtonian.The Newtonian telescope was the first successful reflecting telescope, completed by Isaac Newton in 1668. It usually has a paraboloid primary mirror but at focal ratios of about f/10 or longer a spherical primary mirror can be sufficient for high visual resolution. A flat secondary mirror reflects the light to a focal plane at the side of.

Reflecting telescope. seldom faster than f/15.## Off-axis designs.There are several designs that try to avoid obstructing the incoming light by eliminating the secondary or moving any secondary element off the primary mirror's optical axis, commonly called off-axis optical systems.## Herschelian.The Herschelian reflector is named after William Herschel, who used this design to build very large telescopes including the 40-foot telescope in 1789. In the Herschelian reflector the primary mirror is tilted so the observer's head does not block the incoming light. Although this introduces geometrical aberrations, Herschel employed this design to avoid the use of a Newtonian secondary mirror since the speculum.

Chickpea. The chickpea or chick pea ("Cicer arietinum") is an annual legume of the family Fabaceae, subfamily Faboideae. Its different types are variously known as gram or Bengal gram, garbanzo or garbanzo bean, or Egyptian pea. Chickpea seeds are high in protein. It is one of the earliest cultivated legumes, and 9500-year-old remains have been found in the Middle East.The chickpea is a key ingredient in Mediterranean and Middle Eastern cuisines, used in hummus, and, when ground into flour, falafel. It also is important in Indian cuisine, used in salads, soups and stews, and curry, in chana masala, and in other.

Chickpea. meal products like channa. In 2019, India was responsible for 70% of global chickpea production.## Etymology.The name "chickpea", earlier "chiche pease", is modelled on Middle French ', where "chiche" comes from Latin '. "Chich" was used by itself in English from the 14th to the 18th centuries. The word ', from an alteration of Old Spanish ', came first to English as "garvance" in the 17th century, being gradually anglicized to "calavance", though that came to refer to a variety of other beans, including the hyacinth bean. The current form "garbanzo" comes directly from modern Spanish.## History."Cicer reticulatum" is the.

Chickpea. of "Cicer arietinum", commonly known as the [[perennial plant|perennial]] chickpea. Heat cultivation and macronutrient coupling are two relatively unknown methods that are used to increase the yield and size of the chickpea. Recent research has indicated that a combination of heat treatment along with the two vital macronutrients, phosphorus and nitrogen, are the most critical components to increasing the overall yield of "Cicer arietinum".Perennial chickpeas are a fundamental source of nutrition in animal feed as they are high sources of energy and protein for livestock. Unlike other food crops, the perennial chickpea shows a remarkable capacity to change its nutritional.

Chickpea. incrementally increases the height of the chickpea plant. Thus, the seasonal changes in phosphorus soil content as well as periods of drought that are known to be a native characteristic of the dry [[Middle East|Middle-Eastern]] region where the chickpea is most commonly cultivated have a strong effect on the growth of the plant itself. Plant yield is also affected by a combination of phosphorus nutrition and water supply, resulting in a 12% increase in yield of the crop.Nitrogen nutrition is another factor that affects the yield of "Cicer arietinum", although the application itself differs from other perennial crops with regards.

Chickpea. to the levels administered on the plant. High doses of nitrogen inhibit the yield of the chickpea plant. Drought stress is a likely factor that also inhibits the uptake of nitrogen and subsequent fixation in the roots of "Cicer arietinum". The growth of the perennial chickpea is dependent on the balance between nitrogen fixation and assimilation that is also characteristic of many other agricultural plant types. The influence of drought stress, sowing date, and mineral nitrogen supply all have an effect on the yield and size of the plant, with trials showing that "Cicer arietinum" differed from other plant species.

Anderton Boat Lift. The Anderton Boat Lift is a two caisson lift lock near the village of Anderton, Cheshire, in North West England. It provides a 50 (ft) vertical link between two navigable waterways: the River Weaver and the Trent and Mersey Canal. The structure is designated as a scheduled monument, and is included in the National Heritage List for England; it is also known as one of the Seven Wonders of the Waterways.Built in 1875, the boat lift was in use for over 100 years until it was closed in 1983 due to corrosion. Restoration started in 2001 and the boat lift.

Anderton Boat Lift. was re-opened in 2002. The lift and associated visitor centre and exhibition are operated by the Canal & River Trust. It is one of only two working boat lifts in the United Kingdom; the other is the Falkirk Wheel in Scotland.## Economic background.Salt has been extracted from rock salt beds underneath the Cheshire Plain since Roman times. By the end of the 17th century a major salt mining industry had developed around the Cheshire "salt towns" of Northwich, Middlewich, Nantwich and Winsford.Completion of the River Weaver Navigation in 1734 provided a navigable route for transporting salt from Winsford, through Northwich,.

Anderton Boat Lift. to Frodsham, where the Weaver joins the River Mersey. In 1759 the second Weaver Navigation Act appointed the Trustees of the Weaver Navigation and gave them responsibility for maintaining and operating the route. The opening of the Trent and Mersey Canal in 1777 provided a second route close to the Weaver Navigation for part of its length, but extended further south to the coal mining and pottery industries around Stoke-on-Trent.Rather than competing with each other the owners of the two waterways decided it would be more profitable to work together. In 1793 a basin was excavated on the north bank.

Anderton Boat Lift. owners of the Trent and Mersey Canal, to ask for a contribution towards the cost. When this approach was unsuccessful the Trustees decided to fund the project themselves.The Trustees asked their Chief Engineer, Edward Leader Williams, to draw up plans for a boat lift. He settled on a design involving a pair of water-filled caissons that would counterbalance one another and require relatively little power to lift boats up and down. A similar boat lift on the Grand Western Canal, completed in 1835, used chains to connect the caissons via an overhead balance wheel. It had a solid masonry superstructure.

Anderton Boat Lift. in normal operation.## Construction.In October 1871 the Weaver Navigation Trustees held a special general meeting which resolved "to consider the desirability of constructing a lift with basins and all other requisite works for the interchange of traffic between the River Weaver and the North Staffordshire Canal at Anderton and of applying to Parliament for an Act to authorise the construction of such works."In July 1872 Royal Assent was granted for the Weaver Navigation 1872 Act, which authorised the construction of the boat lift. The contract for its construction was awarded to Emmerson, Murgatroyd & Co. of Stockport and Liverpool. Work.

It was originally intended to restore the lift to electrical operation but after consultation with English Heritage, in 1997 it was decided to restore the lift to hydraulic operation using hydraulic oil.To raise the £7 million restoration cost, a partnership was forged between the Waterways Trust, the Inland Waterways Association, the Anderton Boat Lift Trust, the Friends of Anderton Boat Lift, the Association of Waterways Cruising Clubs, British Waterways and the Trent and Mersey Canal Society. Heritage Lottery Funding contributed £3.3 million, and more than 2,000 individuals contributed to the scheme, raising a further £430,000.Restoration commenced.

Confederation Bridge. The Confederation Bridge () is a box girder bridge carrying the Trans-Canada Highway across the Abegweit Passage of the Northumberland Strait, linking the province of Prince Edward Island with the province of New Brunswick on the mainland. Opened May 31, 1997, the 12.9 (km) bridge is Canada's longest bridge and the world's longest bridge over ice-covered water.Construction took place from October 1993 to May 1997 and cost C$1.3 billion. Before its official naming, Prince Edward Islanders often referred to the bridge as the "Fixed Link". It officially opened to traffic on May 31, 1997. In April 2022, the PEI legislature.

Confederation Bridge. was at the 13 (km) wide Abegweit Passage. Infrequent winter service provided by underpowered steamships incapable of breaking sea ice ensured the survival of a passenger and mail service across Abegweit Passage using iceboats until a permanent ferry service was established in the 1910s.The unsatisfactory winter steamship service and reliance upon primitive iceboats provoked complaints from the Island government until the federal government decided to implement a railcar ferry service across Abegweit Passage between new ports at Port Borden and Cape Tormentine.In 1912, the federal government promised to open a car ferry between the "Capes" (Cape Traverse, PEI to Cape.

Howlan also raised the issue as a member of the provincial Legislative Assembly, and in 1891, as a Senator and member of a delegation to meetings on the subject, conducted at the British Parliament. The idea lost favour following his death in 1901.Talk of a fixed link was revived in.

The topic was raised in 1957, only two years following the opening of the Canso Causeway, and at the same time as another mega-project, the St. Lawrence Seaway was being constructed. A rockfill causeway was proposed to cross Abegweit Passage, with a 300 (m) bridge/tunnel to accommodate shipping. This plan was rejected for navigational reasons but was raised again in 1962, and in 1965, the federal government, ignoring concerns of the shipping industry, called for tenders for a $148 million fixed link featuring a tunnel/causeway/bridge. Approach roads and railway lines were.

Confederation Bridge. constructed at Borden and Jourimain Island but the project was formally abandoned in 1969 upon scientific recommendation in favour of improved ferry services.Due to the extremely complex tidal regime in the Northumberland Strait consisting of diurnal and semi-diurnal cycles, any attempt to close Abegweit Passage would be next to impossible since the tidal cycles on each side of a causeway would be placed at opposites to each other. It is estimated by tidal experts at the Canadian Hydrographic Service, that tidal currents through a gap in such a causeway would be in excess of 18 (kn), powerful enough to counter.

These crawler transports, using specially designed teflon-coated concrete rails, earned the nickname "lobsters" from workers.All major components were lifted from the Amherst Head staging facility, transported, and placed in Abegweit Passage using the HLV "Svanen", a Dutch-built heavy lift catamaran, which during the construction of the fixed link was reportedly the tallest man-made structure in the province.

The economic impact of construction on Prince Edward Island was substantial, with the provincial GDP rising over 5% during the construction, providing a short-term economic boom for the Island.It neared completion in April 1997.## Naming.Throughout construction, the federal government received suggestions for names. A committee was formed on.

Confederation Bridge. May 1, 1996, chaired by former PEI Premier Alex Campbell, to choose the new name from the submissions. The committee chose the name "Abegweit Crossing", which would pay homage to the Abegweit Passage which the bridge crosses, the vessel M/V "Abegweit" which the bridge would replace, and to the Mi'kmaq traditional name for the island.However, the Canadian government overruled the committee, and on September 27, 1996, the Minister of Public Works and Government Services Diane Marleau announced that the bridge's name would be "Confederation Bridge". This name is not without controversy as many Islanders feel the word "Confederation" is overused.

They are spread when raindrops hit the cups and splash the seeds out.It grows in high quality mesic forests on moist, mossy ledges and north-facing slopes. The Latin specific epithet "diphylla" means two-leaved and is in reference to the non-basal leaves.## Ecology.The flowers produce both pollen and nectar. Due to their small size, they are mainly visited by small bees and flies: for instance, "Lasioglossum" sweat bees, small carpenter bees ("Ceratina") and hoverflies.## Cultivation.This species is grown as an ornamental plant in shade gardens. It prefers wet-mesic to dry soil and partial.

Aqua-Lung. Aqua-Lung was the first open-circuit, self-contained underwater breathing apparatus (or "scuba") to achieve worldwide popularity and commercial success. This class of equipment is now commonly referred to as a twin-hose diving regulator, or demand valve. The Aqua-Lung was invented in France during the winter of 1942–1943 by two Frenchmen: the engineer Émile Gagnan and the Naval Lieutenant (French: "lieutenant de vaisseau") Jacques Cousteau.

Gagnan's boss, Henri Melchior, knew that his son-in-law Jacques-Yves Cousteau was looking for an automatic demand regulator to increase the useful endurance of the underwater breathing apparatus invented by Commander Yves le Prieur, so he introduced Cousteau to Gagnan in December 1942. On Cousteau's initiative, the Gagnan regulator was modified for use in diving. Cousteau and Gagnan were issued a patent.

The term "Aqualung", as far as is known, first appeared in print on page 3 of Jacques-Yves Cousteau's first book, "The Silent World", in 1953. Public use of the word "aqualung", and public interest in Aqualungs and scuba diving, were started around 1953 in English-speaking counties by a National Geographical Society Magazine article about Cousteau's underwater archaeological expedition to Grand Congloué. In France, aqualung diving was popularized by Cousteau's movie "Épaves", while his book.

Cuscuta gronovii. Cuscuta gronovii is a yellow vine that grows as a parasite off other plants. It is a dicot.## Description."Cuscuta gronovii" belongs to the family Convolvuaceae, including the morning glories, comprising about 200 species. It is a parasitic annual vine that infects host plants in a parasitic relationship. Its stems appear orange-yellow in color. The vine can grow up to a length of one meter or more, entangling itself around the host plant. Although it appears to be leafless, it has tiny, alternate, scale-like leaves. The vine produces white flowers with bell-shaped, five-lobed corollas, and sepals united at the base. The.

Cuscuta gronovii. flowers are roughly 1/8 of an inch apart from one another.There are currently three known subspecies of "Cuscuta gronovii": "calyptrata", "gronovii", and "latiflora".## Etymology."Cuscuta gronovii" was named in honor of botanist Jay Fredrik Gronon. The genus "Cuscuta" was named after the Arabic word for "dodders", and the word dodder originates from an Old English word meaning "todder".There are four widely used common names for this species: scaldweed, common dodder, swamp dodder, and love dodder.## Distribution and ecology.The common dodder can be found in every state of the United States with the exceptions of Utah, Nevada, California, Washington, Alaska and Hawaii.

Cuscuta gronovii. It can also be found in all provinces of Canada with the exceptions of British Columbia, Yukon, Northwest Territories, and Nunavut. The plant is native in all of these areas.This species has naturalized in France, Germany, Luxembourg, the Netherlands, and Italy.This species is commonly found growing in temperate forest habitats. Because it requires an abundance of moisture, the common dodder is usually found in floodplains.## Life cycle.Plants within the genus "Cuscuta" generally do not contain chlorophyll, nor are they photosynthetically active. This species, however, does contain a small amount of chlorophyll. It is not enough to support the plant via.

This is why the common dodder is dependent upon other plants to survive.The life cycle begins with germination, but seeds are unable to survive long periods of time without first associating themselves with host plants. Adult plants wind themselves around their host and begin the attachment phase. Parenchymal cells begin pre-haustoria development. The next phase is referred to as the penetration phase, where the host plant is punctured through by a fully developed haustoria. This process allows for water and macromolecules to be transferred from the host to the plant. While this can be harmful for the host.

Cane toad. The cane toad (Rhinella marina), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia. It is a member of the genus "Rhinella", which includes many true toad species found throughout Central and South America, but it was formerly assigned to the genus "Bufo".The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene in Colombia is indistinguishable.

Cane toad. from modern cane toads from northern South America. It was discovered in a floodplain deposit, which suggests the "R. marina" habitat preferences have long been for open areas. The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs. Its reproductive success is partly because of opportunistic feeding: it has a diet, unusual among anurans, of both dead and living matter. Adults average 10 – 15 (cm) in length; the largest recorded specimen had a snout-vent length of 24 (cm).The cane toad has poison glands, and the tadpoles are highly toxic to most animals if ingested.

Cane toad. Its toxic skin can kill many animals, both wild and domesticated, and cane toads are particularly dangerous to dogs. Because of its voracious appetite, the cane toad has been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control. The common name of the species is derived from its use against the cane beetle ("Dermolepida albohirtum"), which damages sugar cane. The cane toad is now considered a pest and an invasive species in many of its introduced regions. The 1988 film "" documented the trials and tribulations of the introduction of cane.

Cane toad. toads in Australia.## Taxonomy.Historically, the cane toads were used to eradicate pests from sugarcane, giving rise to their common name. The cane toad has many other common names, including "giant toad" and "marine toad"; the former refers to its size, and the latter to the binomial name, "R. marina". It was one of many species described by Carl Linnaeus in his 18th-century work "Systema Naturae" (1758). Linnaeus based the specific epithet "marina" on an illustration by Dutch zoologist Albertus Seba, who mistakenly believed the cane toad to inhabit both terrestrial and marine environments. Other common names include "giant neotropical toad",.

Cane toad. "Dominican toad", "giant marine toad", and "South American cane toad". In Trinidadian English, they are commonly called "crapaud", the French word for toad.The genus "Rhinella" is considered to constitute a distinct genus of its own, thus changing the scientific name of the cane toad. In this case, the specific name "marinus" (masculine) changes to "marina" (feminine) to conform with the rules of gender agreement as set out by the International Code of Zoological Nomenclature, changing the binomial name from "Bufo marinus" to "Rhinella marina"; the binomial "Rhinella marinus" was subsequently introduced as a synonym through misspelling by Pramuk, Robertson, Sites,.

Cane toad. and Noonan (2008). Though controversial (with many traditional herpetologists still using "Bufo marinus") the binomial "Rhinella marina" is gaining in acceptance with such bodies as the IUCN, Encyclopaedia of Life, Amphibian Species of the World and increasing numbers of scientific publications adopting its usage.Since 2016, cane toad populations native to Mesoamerica and northwestern South America are sometimes considered to be a separate species, "Rhinella horribilis".In Australia, the adults may be confused with large native frogs from the genera "Limnodynastes", "Cyclorana", and "Mixophyes". These species can be distinguished from the cane toad by the absence of large parotoid glands behind their.

Cane toad. eyes and the lack of a ridge between the nostril and the eye. Cane toads have been confused with the giant burrowing frog ("Heleioporus australiacus"), because both are large and warty in appearance; however, the latter can be readily distinguished from the former by its vertical pupils and its silver-grey (as opposed to gold) irises. Juvenile cane toads may be confused with species of the genus "Uperoleia", but their adult colleagues can be distinguished by the lack of bright colouring on the groin and thighs.In the United States, the cane toad closely resembles many bufonid species. In particular, it could.

Cane toad. be confused with the southern toad ("Bufo terrestris"), which can be distinguished by the presence of two bulbs in front of the parotoid glands.## Genetics.The cane toad genome has been sequenced and certain Australian academics believe this will help in understanding how the toad can quickly evolve to adapt to new environments, the workings of its infamous toxin, and hopefully provide new options for halting this species' march across Australia and other places it has spread as an invasive pest.## Description.Considered the largest species in the Bufonidae, the cane toad is very large; the females are significantly longer than males,.

Cane toad. toads lose the toxicity that protected them as eggs and tadpoles, but have yet to fully develop the parotoid glands that produce bufotoxin. Only an estimated 0.5% of cane toads reach adulthood, in part because they lack this key defense - but also due to tadpole cannibalism. Although cannibalism does occur in the native population in South America, the rapid evolution occurring in the unnaturally large population in Australia has produced tadpoles 30x more likely to be "interested" in cannibalising their siblings, and 2.6x more likely to actually "do so". They have also evolved to shorten their tadpole phase in.

Cane toad. consumption of cane toads. Dogs are especially prone to be poisoned by licking or biting toads. Pets showing excessive drooling, extremely red gums, head-shaking, crying, loss of coordination, and/or convulsions require immediate veterinary attention.Bufotenin, one of the chemicals excreted by the cane toad, is classified as a schedule 9 drug under Australian law, alongside heroin and LSD. The effects of bufotenin are thought to be similar to those of mild poisoning; the stimulation, which includes mild hallucinations, lasts less than an hour. As the cane toad excretes bufotenin in small amounts, and other toxins in relatively large quantities, toad licking.

Cane toad. could result in serious illness or death.In addition to releasing toxin, the cane toad is capable of inflating its lungs, puffing up, and lifting its body off the ground to appear taller and larger to a potential predator.Since 2011, experimenters in the Kimberley region of Western Australia have used poisonous sausages containing toad meat in an attempt to protect native animals from cane toads' deadly impact. The Western Australian Department of Environment and Conservation, along with the University of Sydney, developed these sausage-shaped baits as a tool in order to train native animals not to eat the toads. By blending.

Cane toad. bits of toad with a nausea-inducing chemical, the baits train the animals to stay away from the amphibians.## Predators.Many species prey on the cane toad and its tadpoles in its native habitat, including the broad-snouted caiman ("Caiman latirostris"), the banded cat-eyed snake ("Leptodeira annulata"), eels (family Anguillidae), various species of killifish, the rock flagtail ("Kuhlia rupestris"), some species of catfish (order Siluriformes), some species of ibis (subfamily Threskiornithinae), and "Paraponera clavata" (bullet ants).Predators outside the cane toad's native range include the whistling kite ("Haliastur sphenurus"), the rakali ("Hydromys chrysogaster"), the black rat ("Rattus rattus") and the water monitor ("Varanus salvator").

Cane toad. The tawny frogmouth ("Podargus strigoides") and the Papuan frogmouth ("Podargus papuensis") have been reported as feeding on cane toads; some Australian crows ("Corvus" spp.) have also learned strategies allowing them to feed on cane toads, such as using their beak to flip toads onto their backs.Opossums of the genus "Didelphis" likely can eat cane toads with impunity. Meat ants are unaffected by the cane toads' toxins, so are able to kill them. The cane toad's normal response to attack is to stand still and let its toxin kill the attacker, which allows the ants to attack and eat the toad.

Cane toad. to 2% of the density in Australia.## As an introduced species.The cane toad has been introduced to many regions of the world—particularly the Pacific—for the biological control of agricultural pests. These introductions have generally been well documented, and the cane toad may be one of the most studied of any introduced species.Before the early 1840s, the cane toad had been introduced into Martinique and Barbados, from French Guiana and Guyana. An introduction to Jamaica was made in 1844 in an attempt to reduce the rat population. Despite its failure to control the rodents, the cane toad was introduced to Puerto.

Cane toad. Rico in the early 20th century in the hope that it would counter a beetle infestation ravaging the sugarcane plantations. The Puerto Rican scheme was successful and halted the economic damage caused by the beetles, prompting scientists in the 1930s to promote it as an ideal solution to agricultural pests.As a result, many countries in the Pacific region emulated the lead of Puerto Rico and introduced the toad in the 1930s. Introduced populations are in Australia, Florida, Papua New Guinea, the Philippines, the Ogasawara, Ishigaki Island and the Daitō Islands of Japan, most Caribbean islands, Fiji and many other Pacific.

Cane toad. islands, including Hawaii. Since then, the cane toad has become a pest in many host countries, and poses a serious threat to native animals.## Australia.Following the apparent success of the cane toad in eating the beetles threatening the sugarcane plantations of Puerto Rico, and the fruitful introductions into Hawaii and the Philippines, a strong push was made for the cane toad to be released in Australia to negate the pests ravaging the Queensland cane fields. As a result, 102 toads were collected from Hawaii and brought to Australia. Queensland's sugar scientists released the toad into cane fields in August 1935.

Cane toad. After this initial release, the Commonwealth Department of Health decided to ban future introductions until a study was conducted into the feeding habits of the toad. The study was completed in 1936 and the ban lifted, when large-scale releases were undertaken; by March 1937, 62,000 toadlets had been released into the wild. The toads became firmly established in Queensland, increasing exponentially in number and extending their range into the Northern Territory and New South Wales. In 2010, one was found on the far western coast in Broome, Western Australia.However, the toad was generally unsuccessful in reducing the targeted grey-backed cane.

Cane toad. beetles ("Dermolepida albohirtum"), in part because the cane fields provided insufficient shelter for the predators during the day, and in part because the beetles live at the tops of sugar cane—and cane toads are not good climbers. Since its original introduction, the cane toad has had a particularly marked effect on Australian biodiversity. The population of a number of native predatory reptiles has declined, such as the varanid lizards "Varanus mertensi", "V. mitchelli", and "V. panoptes", the land snakes "Pseudechis australis" and "Acanthophis antarcticus", and the crocodile species "Crocodylus johnstoni"; in contrast, the population of the agamid lizard "Amphibolurus gilberti"—known.

Cane toad. the toads became abundant, they have done even less to control the pests than in Australia. The toad was introduced to Martinique from French Guiana before 1944 and became established. Today, they reduce the mosquito and mole cricket populations. A third introduction to the region occurred in 1884, when toads appeared in Jamaica, reportedly imported from Barbados to help control the rodent population. While they had no significant effect on the rats, they nevertheless became well established. Other introductions include the release on Antigua—possibly before 1916, although this initial population may have died out by 1934 and been reintroduced at.

Cane toad. islands in Fiji, although they tend to be smaller than their counterparts in other regions.## New Guinea.The cane toad was introduced into New Guinea to control the hawk moth larvae eating sweet potato crops. The first release occurred in 1937 using toads imported from Hawaii, with a second release the same year using specimens from the Australian mainland. Evidence suggests a third release in 1938, consisting of toads being used for human pregnancy tests—many species of toad were found to be effective for this task, and were employed for about 20 years after the discovery was announced in 1948. Initial.

Cane toad. reports argued the toads were effective in reducing the levels of cutworms and sweet potato yields were thought to be improving. As a result, these first releases were followed by further distributions across much of the region, although their effectiveness on other crops, such as cabbages, has been questioned; when the toads were released at Wau, the cabbages provided insufficient shelter and the toads rapidly left the immediate area for the superior shelter offered by the forest. A similar situation had previously arisen in the Australian cane fields, but this experience was either unknown or ignored in New Guinea. The.

Cane toad. As a laboratory animal, the cane toad has numerous advantages: they are plentiful, and easy and inexpensive to maintain and handle. The use of the cane toad in experiments started in the 1950s, and by the end of the 1960s, large numbers were being collected and exported to high schools and universities. Since then, a number of Australian states have introduced or tightened importation regulations.There are several commercial uses for dead cane toads. Cane toad skin is made into leather and novelty items. Stuffed cane toads, posed and accessorised, are merchandised at souvenir shops for tourists. Attempts have been made.

Cane toad. to produce fertiliser from toad carcasses.## Invasive species.Cane toads pose a serious threat to native species when introduced to a new ecosystem. Classified as an invasive species in over 20 countries, multiple reports exist of the cane toad moving into a new area to be followed by a decline in the biodiversity in that region. The most documented region of the cane toad's invasion and subsequent effect on native species is Australia, where multiple surveys and observations of the toad's conquest have been completed. The best way to illustrate this effect is through the plight of the northern quoll, as.

Cane toad. the quoll population began at the Mary River ranger station using radio tracking in 2002, months before the first cane toads arrived at the site. After the arrival of the cane toads, the population of northern quolls in the Mary River site plummeted between October and December 2002, and by March 2003, the northern quoll appeared to be extinct in this section of the park, as no northern quolls were caught in the trapping trips in the following two months. In contrast, the population of northern quolls in the control site at the East Alligator ranger station remained relatively constant,.

Huis Ten Bosch (theme park). is on Hario Island, essentially an area of reclaimed marshland on the main coastline of Kyushu facing Ōmura Bay. Its location in this area of the country reflects the historical relations between the Netherlands and Japan, which began in 1609 when a trading post was opened by the Dutch in Hirado, an island off the coast of Kyushu around 35 km northwest of central Sasebo.The Huis Ten Bosch park is open daily from 9.00 a.m. to 9.30 p.m. (9.00 a.m. to 8.30 p.m. from December to February). A day "passport" ticket, covering entry and a number of attractions within the.

Huis Ten Bosch (theme park). park costs 5,600 yen for adults and 4,400 yen for children. The park can be reached by JR train or bus from Nagasaki. It can also be reached by boat from Nagasaki Airport or from Sasebo.The park recorded the peak of 4.25 million visitors in 1996. However, due to the fall of the number of visitors caused by economic slump in Japan, the park declared bankruptcy in 2003 with debt of 220 billion yen. The rebuilding plan was sponsored by Nomura Principal Finance Company until March 2010, when H.I.S., a travel agency, took over the management by injecting 2 billion.

Power inverter. A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as.

Power inverter. a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.## Input and output.## Input voltage.A typical power inverter device or circuit requires a stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the.

Power inverter. are two basic designs for producing household plug-in voltage from a lower-voltage DC source, the first of which uses a switching boost converter to produce a higher-voltage DC and then converts to AC. The second method converts DC to AC at battery level and uses a line-frequency transformer to create the output voltage.## Square wave.This is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce "humming" when connected to audio equipment and is generally unsuitable for sensitive electronics.## Sine wave.A power inverter.

Power inverter. device that produces a multiple step sinusoidal AC waveform is referred to as a "sine wave inverter". To more clearly distinguish the inverters with outputs of much less distortion than the "modified sine wave" (three-step) inverter designs, the manufacturers often use the phrase "pure sine wave inverter". Almost all consumer grade inverters that are sold as a "pure sine wave inverter" do not produce a smooth sine wave output at all, just a less choppy output than the square wave (two-step) and modified sine wave (three-step) inverters. However, this is not critical for most electronics as they deal with the.

Power inverter. output quite well.Where power inverter devices substitute for standard line power, a sine wave output is desirable because many electrical products are engineered to work best with a sine wave AC power source. The standard electric utility provides a sine wave, typically with minor imperfections but sometimes with significant distortion.Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling. Switch-mode power supply (SMPS) devices, such as personal computers or DVD.

Power inverter. players, function on modified sine wave power. AC motors directly operated on non-sinusoidal power may produce extra heat, may have different speed-torque characteristics, or may produce more audible noise than when running on sinusoidal power.## Modified sine wave.The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a waveform which has voltage steps of zero, peak positive, zero, peak negative and again zero. This voltage value sequence is repeated continuously. The resultant voltage waveform better approximates the shape of a sinusoidal voltage.

Power inverter. entirely without problems, but if the item has a mains transformer, this can overheat depending on how marginally it is rated.However, the load may operate less efficiently owing to the harmonics associated with a modified sine wave and produce a humming noise during operation. This also affects the efficiency of the system as a whole, since the manufacturer's nominal conversion efficiency does not account for harmonics. Therefore, pure sine wave inverters may provide significantly higher efficiency than modified sine wave inverters.Most AC motors will run on MSW inverters with an efficiency reduction of about 20% owing to the harmonic content.

Power inverter. DC supply, in the manner of the MSN designs, but the switching takes place at a far faster rate, typically many KHz, so that the varying width of the pulses can be smoothed to create the sine wave. If a microprocessor is used to generate the switching timing, the harmonic content and efficiency can be closely controlled.## Output frequency.The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. The exception is in designs for motor driving, where a variable frequency results in a variable speed control.Also, if the.

Power inverter. output of the device or circuit is to be further conditioned (for example stepped up) then the frequency may be much higher for good transformer efficiency.## Output voltage.The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.Some inverters also allow selectable or continuously variable output voltages.## Output power.A power inverter will often have an overall.

Power inverter. battery from the others.## Applications.## DC power source usage.An inverter converts the DC electricity from sources such as batteries or fuel cells to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage.## Uninterruptible power supplies.An uninterruptible power supply (UPS) uses batteries and an inverter to supply AC power when mains power is not available. When mains power is restored, a rectifier supplies DC power to recharge the batteries.## Electric motor speed control.Inverter circuits designed to produce a variable output.

Power inverter. voltage range are often used within motor speed controllers.The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load. Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools.Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table 1. The generated.

Power inverter. gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.## In refrigeration compressors.An inverter can be used to control the speed of the compressor motor to drive variable refrigerant flow in a refrigeration or air conditioning system to regulate system performance. Such installations are known as inverter compressors. Traditional methods of refrigeration regulation use single-speed compressors switched on and off periodically; inverter-equipped systems have a variable-frequency drive that control the speed of the motor and thus the compressor and cooling output. The variable-frequency AC from the inverter drives a brushless or.

Power inverter. induction motor, the speed of which is proportional to the frequency of the AC it is fed, so the compressor can be run at variable speeds—eliminating compressor stop-start cycles increases efficiency. A microcontroller typically monitors the temperature in the space to be cooled, and adjusts the speed of the compressor to maintain the desired temperature. The additional electronics and system hardware add cost to the equipment, but can result in substantial savings in operating costs. The first inverter air conditioners were released by Toshiba in 1981, in Japan.## Power grid.Grid-tied inverters are designed to feed into the electric power distribution.

Power inverter. hundred megawatts, are used to deliver power from high voltage direct current transmission systems to alternating current distribution systems.## Solar.A solar inverter is a balance of system (BOS) component of a photovoltaic system and can be used for both grid-connected and off-grid systems. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.Solar micro-inverters differ from conventional inverters, as an individual micro-inverter is attached to each solar panel. This can improve the overall efficiency of the system. The output from several micro-inverters is then combined and often fed to the electrical.

Power inverter. grid.In other applications, a conventional inverter can be combined with a battery bank maintained by a solar charge controller. This combination of components is often referred to as a solar generator.Solar inverters are also used in spacecraft photovoltaic system.## Induction heating.Inverters convert low frequency main AC power to higher frequency for use in induction heating. To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC sources employed, the structure becomes more reliable and the output voltage has.

Power inverter. higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved. This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors.There are three kinds of level shifted modulation techniques, namely: Phase Opposition Disposition (POD) Alternative Phase Opposition Disposition (APOD) Phase Disposition (PD)## HVDC power transmission.With HVDC power transmission, AC power is rectified and high voltage DC power is transmitted to another location. At the receiving location, an inverter in a static inverter.

Power inverter. plant converts the power back to AC. The inverter must be synchronized with grid frequency and phase and minimize harmonic generation.## Electroshock weapons.Electroshock weapons and tasers have a DC/AC inverter to generate several tens of thousands of V AC out of a small 9 V DC battery. First the 9 V DC is converted to 400–2000 V AC with a compact high frequency transformer, which is then rectified and temporarily stored in a high voltage capacitor until a pre-set threshold voltage is reached. When the threshold (set by way of an airgap or TRIAC) is reached, the capacitor dumps its.

Power inverter. entire load into a pulse transformer which then steps it up to its final output voltage of 20–60 kV. A variant of the principle is also used in electronic flash and bug zappers, though they rely on a capacitor-based voltage multiplier to achieve their high voltage.## Miscellaneous.Typical applications for power inverters include: Portable consumer devices that allow the user to connect a battery, or set of batteries, to the device to produce AC power to run various electrical items such as lights, televisions, kitchen appliances, and power tools. Use in power generation systems such as electric utility companies or solar.

Power inverter. generating systems to convert DC power to AC power. Use within any larger electronic system where an engineering need exists for deriving an AC source from a DC source. Frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.## Circuit description.## Basic design.In one simple inverter circuit,.

Power inverter. DC power is connected to a transformer through the center tap of the primary winding. A relay switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit.The electromechanical version of the switching device includes two stationary contacts and a spring supported moving contact. The spring holds the movable contact against one of the stationary contacts and.

Power inverter. provide large power handling capability in a semiconductor device, and can readily be controlled over a variable firing range.The switch in the simple inverter described above, when not coupled to an output transformer, produces a square voltage waveform due to its simple off and on nature as opposed to the sinusoidal waveform that is the usual waveform of an AC power supply. Using Fourier analysis, periodic waveforms are represented as the sum of an infinite series of sine waves. The sine wave that has the same frequency as the original waveform is called the fundamental component. The other sine waves,.

Power inverter. car that is moving can turn into a source of energy and can, with the right inverter topology (full H-bridge) charge the car battery when decelerating or braking. In a similar manner, the right topology (full H-bridge) can invert the roles of "source" and "load", that is, if for example the voltage is higher on the AC "load" side (by adding a solar inverter, similar to a gen-set, but solid state), energy can flow back into the DC "source" or battery.Based on the basic H-bridge topology, there are two different fundamental control strategies called basic frequency-variable bridge converter and PWM.

Power inverter. control. Here, in the left image of H-bridge circuit, the top left switch is named as "S1", and others are named as "S2, S3, S4" in counterclockwise order.For the basic frequency-variable bridge converter, the switches can be operated at the same frequency as the AC in the electric grid. However, it is the rate at which the switches open and close that determines the AC frequency. When S1 and S4 are on and the other two are off, the load is provided with positive voltage and vice versa. We could control the on-off states of the switches to adjust the.

Power inverter. AC magnitude and phase. We could also control the switches to eliminate certain harmonics. This includes controlling the switches to create notches, or 0-state regions, in the output waveform or adding the outputs of two or more converters in parallel that are phase shifted in respect to one another.Another method that can be used is PWM. Unlike the basic frequency-variable bridge converter, in the PWM controlling strategy, only two switches S3, S4 can operate at the frequency of the AC side or at any low frequency. The other two would switch much faster (typically 100 KHz) to create square voltages.

Power inverter. level of distortion caused by harmonics. The waveform quality of AC produced directly by H-bridge mentioned above would be not as good as we want.The issue of waveform quality can be addressed in many ways. Capacitors and inductors can be used to filter the waveform. If the design includes a transformer, filtering can be applied to the primary or the secondary side of the transformer or to both sides. Low-pass filters are applied to allow the fundamental component of the waveform to pass to the output while limiting the passage of the harmonic components. If the inverter is designed to.

Power inverter. provide power at a fixed frequency, a resonant filter can be used. For an adjustable frequency inverter, the filter must be tuned to a frequency that is above the maximum fundamental frequency.Since most loads contain inductance, feedback rectifiers or antiparallel diodes are often connected across each semiconductor switch to provide a path for the peak inductive load current when the switch is turned off. The antiparallel diodes are somewhat similar to the "freewheeling diodes" used in AC/DC converter circuits.Fourier analysis reveals that a waveform, like a square wave, that is anti-symmetrical about the 180 degree point contains only odd harmonics,.

Power inverter. simplifies the electronics, but the inductors and capacitors tend to be large and heavy. Its high efficiency makes this approach popular in large uninterruptible power supplies in data centers that run the inverter continuously in an "online" mode to avoid any switchover transient when power is lost.A closely related approach uses a ferroresonant transformer, also known as a constant voltage transformer, to remove harmonics and to store enough energy to sustain the load for a few AC cycles. This property makes them useful in standby power supplies to eliminate the switchover transient that otherwise occurs during a power failure while.

Power inverter. size and volume. In 2014, Google together with IEEE started an open competition named Little Box Challenge, with a prize money of $1,000,000, to build a (much) smaller power inverter.## History.## Early inverters.From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas-filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron.The origins of electromechanical inverters explain the source of the term "inverter". Early AC-to-DC converters.

Power inverter. used an induction or synchronous AC motor direct-connected to a generator (dynamo) so that the generator's commutator reversed its connections at exactly the right moments to produce DC. A later development is the synchronous converter, in which the motor and generator windings are combined into one armature, with slip rings at one end and a commutator at the other and only one field frame. The result with either is AC-in, DC-out. With an M-G set, the DC can be considered to be separately generated from the AC; with a synchronous converter, in a certain sense it can be considered to.

Power inverter. be "mechanically rectified AC". Given the right auxiliary and control equipment, an M-G set or rotary converter can be "run backwards", converting DC to AC. Hence an inverter is an inverted converter.## Controlled rectifier inverters.Since early transistors were not available with sufficient voltage and current ratings for most inverter applications, it was the 1957 introduction of the thyristor or silicon-controlled rectifier (SCR) that initiated the transition to solid state inverter circuits.The "commutation" requirements of SCRs are a key consideration in SCR circuit designs. SCRs do not turn off or "commutate" automatically when the gate control signal is shut off. They.

Power inverter. only turn off when the forward current is reduced to below the minimum holding current, which varies with each kind of SCR, through some external process. For SCRs connected to an AC power source, commutation occurs naturally every time the polarity of the source voltage reverses. SCRs connected to a DC power source usually require a means of forced commutation that forces the current to zero when commutation is required. The least complicated SCR circuits employ natural commutation rather than forced commutation. With the addition of forced commutation circuits, SCRs have been used in the types of inverter circuits described.

Power inverter. above.In applications where inverters transfer power from a DC power source to an AC power source, it is possible to use AC-to-DC controlled rectifier circuits operating in the inversion mode. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. This type of operation can be used in HVDC power transmission systems and in regenerative braking operation of motor control systems.Another type of SCR inverter circuit is the current source input (CSI) inverter. A CSI inverter is the dual of a six-step voltage source inverter. With a current source inverter, the DC power supply is configured.

Power inverter. as a current source rather than a voltage source. The inverter SCRs are switched in a six-step sequence to direct the current to a three-phase AC load as a stepped current waveform. CSI inverter commutation methods include load commutation and parallel capacitor commutation. With both methods, the input current regulation assists the commutation. With load commutation, the load is a synchronous motor operated at a leading power factor.As they have become available in higher voltage and current ratings, semiconductors such as transistors or IGBTs that can be turned off by means of control signals have become the preferred switching components.

Power inverter. for use in inverter circuits.## Rectifier and inverter pulse numbers.Rectifier circuits are often classified by the number of current pulses that flow to the DC side of the rectifier per cycle of AC input voltage. A single-phase half-wave rectifier is a one-pulse circuit and a single-phase full-wave rectifier is a two-pulse circuit. A three-phase half-wave rectifier is a three-pulse circuit and a three-phase full-wave rectifier is a six-pulse circuit.With three-phase rectifiers, two or more rectifiers are sometimes connected in series or parallel to obtain higher voltage or current ratings. The rectifier inputs are supplied from special transformers that provide phase.

Power inverter. shifted outputs. This has the effect of phase multiplication. Six phases are obtained from two transformers, twelve phases from three transformers and so on. The associated rectifier circuits are 12-pulse rectifiers, 18-pulse rectifiers and so on...When controlled rectifier circuits are operated in the inversion mode, they would be classified by pulse number also. Rectifier circuits that have a higher pulse number have reduced harmonic content in the AC input current and reduced ripple in the DC output voltage. In the inversion mode, circuits that have a higher pulse number have lower harmonic content in the AC output voltage waveform.## Other.
