title: "Cane toad" content: 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 the world's largest toad. It is a member of the genus "Rhinella", but was formerly in the genus "Bufo", which includes many different true toad species found throughout Central and South America. The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs. Its reproductive success

title: "Cane toad" content: is partly because of opportunistic feeding: it has a diet, unusual among anurans, of both dead and living matter. Adults average in length; the largest recorded specimen had a snout-vent length of . The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene of Colombia is indistinguishable 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 has poison glands, and the tadpoles are highly toxic to

title: "Cane toad" content: most animals if ingested. 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 species derives its common name from its use against the cane beetle ("Dermolepida albohirtum"). The cane toad is now considered a pest and an invasive species in many of its introduced regions; of particular concern is its toxic skin, which kills many animals, both wild and domesticated. Cane toads are particularly dangerous to dogs. Historically, the cane toads were used to eradicate pests from sugarcane, giving rise

title: "Cane toad" content: "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, and Noonan (2008). Though controversial (with many traditional herpetologists still using "Bufo marinus") the binomial "Rhinella

title: "Cane toad" content: 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. 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 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

title: "Cane toad" content: develop the parotoid glands that produce bufotoxin. Because they lack this key defence, only an estimated 0.5% of cane toads reach adulthood. As with rates of growth, the point at which the toads become sexually mature varies across different regions. In New Guinea, sexual maturity is reached by female toads with a snout–vent length between , while toads in Panama achieve maturity when they are between in length. In tropical regions, such as their native habitats, breeding occurs throughout the year, but in subtropical areas, breeding occurs only during warmer periods that coincide with the onset of the wet season.

title: "Cane toad" content: class-1 drug under Australian law, alongside heroin and cannabis. The effects of bufotenin are thought to be similar to those of mild poisoning; the stimulation, which includes mild hallucinations, lasts for less than an hour. As the cane toad excretes bufotenin in small amounts, and other toxins in relatively large quantities, toad licking 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. Poisonous sausages containing toad meat are being trialled

title: "Cane toad" content: in the Kimberley (Western Australia) to try to protect native animals from cane toads' deadly impact. The Western Australian Department of Environment and Conservation has been working with the University of Sydney to develop baits to train native animals not to eat the toads. By blending bits of toad with a nausea-inducing chemical, the baits train the animals to stay away from the amphibians. Researcher David Pearson says trials run in laboratories and in remote parts of the Kimberley region of WA are looking promising, although the baits will not solve the cane toad problem altogether. Many species prey on

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"). The tawny frogmouth ("Podargus strigoides") and the Papuan frogmouth ("Podargus papuensis") have been reported as feeding on cane toads; some Australian

This area encompasses both tropical and semiarid environments. The density of the cane toad is significantly lower within its native distribution than in places where it has been introduced. In South America, the density was recorded to be 20 adults per 100 m (109 yd) of shoreline, 1 to 2% of the density in Australia. 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

title: "Cane toad" content: 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 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

title: "Cane toad" content: 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. There are introduced populations 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 islands, including Hawaii. Since then, the cane toad has become a pest in many host countries, and poses a serious threat to native animals. Following the apparent success of the cane

title: "Cane toad" content: 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. After an initial release in August 1935, 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

title: "Cane toad" content: 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 beetles ("Dermolepida albohirtum"), in part because the cane fields provided insufficient shelter for the predators during the day, in part because the beetles live at the tops of sugar cane – and cane toads are not good climbers. Since

title: "Cane toad" content: 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 to be a prey item of "V. panoptes"—has increased. The cane toad was introduced to various Caribbean islands to counter a number of pests infesting local crops. While it was able to establish itself on some islands, such

title: "Cane toad" content: as Barbados, Jamaica, and Puerto Rico, other introductions, such as in Cuba before 1900 and in 1946, and on the islands of Dominica and Grand Cayman, were unsuccessful. The earliest recorded introductions were to Barbados and Martinique. The Barbados introductions were focused on the biological control of pests damaging the sugarcane crops, and while 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

title: "Cane toad" content: 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 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

title: "Cane toad" content: 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 has since become abundant in rural and urban areas. The cane toad naturally exists in South Texas, but attempts (both deliberate and accidental) have been made to introduce the species to other parts of the country. These include introductions to Florida and to the islands of

New research has suggested that the cane toad's poison may have some applications in treating prostate cancer. Other modern applications of the cane toad include pregnancy testing, as pets, laboratory research, and the production of leather goods. Pregnancy testing was conducted in the mid-20th century by injecting urine from a woman into a male toad's lymph sacs, and if spermatozoa appeared in the toad's urine, the patient was deemed to be pregnant. The tests using

Cane toad skin has been made into leather and novelty items; stuffed cane toads, posed and accessorised, have found a home in the tourist market, and attempts have been made to produce fertiliser from their bodies. Cane toads pose a serious threat to native species when introduced to a new ecosystem. Classified as an invasive species in over 20 countries, there are multiple reports of the cane toad moving into a new area to be

title: "Cane toad" content: 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 well as Mertens' water monitor, a large lizard native to South and Southeast Asia. Two sites were chosen to study the effects of cane toads on the northern quoll, one of which was at Mary River ranger station, which is located in the southern region

title: "Cane toad" content: between October and December 2002, and by March 2003, the northern quoll appeared to be extinct in this section of the park, as there were no northern quolls 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, not showing any symptoms of declining. The evidence from the Kakadu National Park is compelling not only because of the timing of the population of northern quolls plummeting just months after the arrival of the cane toad, but also because in the

title: "Cane toad" content: Mary River region 31% of mortalities within the quoll population were attributed to lethal toxic ingestion, as there were no signs of disease, parasite infestation, or any other obvious changes at the site that could have caused such a rapid decline. The most obvious piece of evidence which supports the hypothesis that the invasion of the cane toads caused the local extinction of the northern quoll is that the closely monitored population of the control group, in the absence of cane toads, showed no signs of decline. In the case of the Mertens' water monitor, there was only one region

title: "Cane toad" content: cane toads entered the Manton Dam Recreation Area. At the end of the study, some scattered population of water monitors remained in the upper sites of the Manton Dam, which suggests that local extinctions occurred at certain shoreline sites within Manton Dam, but a complete extinction of the population did not occur. 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.

Given the distances between the vertices of a tetrahedron the volume can be computed using the Cayley–Menger determinant: where the subscripts represent the vertices and "d" is the pairwise distance between them – i.e., the length of the edge connecting the two vertices. A negative value of the determinant means that a tetrahedron cannot be constructed with the given distances.

A line segment joining a vertex of a tetrahedron with the centroid of the opposite face is called a "median" and a line segment joining the midpoints of two opposite edges is called a "bimedian" of the tetrahedron. Hence there are four medians and three bimedians in a tetrahedron. These seven line segments are all concurrent at a point called the "centroid" of the tetrahedron. In addition the four medians are divided in a 3:1 ratio by the centroid (see Commandino's theorem). The centroid of a tetrahedron is the midpoint

Three angles are the angles of some triangle if and only if their sum is 180° (π radians). What condition on 12 angles is necessary and sufficient for them to be the

title: Tetrahedron content: 12 angles of some tetrahedron? Clearly the sum of the angles of any side of the tetrahedron must be 180°. Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8. The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional. Let be the points of a

title: Spaghetti content: Spaghetti Spaghetti (; sing. "spaghetto") is a long, thin, solid, cylindrical pasta. "Spaghettoni" is a thicker form of spaghetti, while "capellini" is a very thin spaghetti. It is a staple food of traditional Italian cuisine. Like other pasta, spaghetti is made of milled wheat and water and sometimes enriched with vitamins and minerals. Authentic Italian spaghetti is made from durum wheat semolina, but elsewhere it may be made with other kinds of flour. Typically the pasta is white because refined flour is used, but whole wheat flour may be added. Originally, spaghetti was notably long, but shorter lengths gained in

A variety of pasta dishes are based on it, and it is frequently served with tomato sauce or meat or vegetables. "Spaghetti" is the plural form of the Italian word "spaghetto", which is a diminutive of "spago", meaning "thin string" or "twine". The first written record of pasta comes from the Talmud in the 5th century AD and refers to dried pasta that could be cooked through boiling, which was conveniently portable. Some historians think that Berbers introduced pasta to Europe during

title: Spaghetti content: a conquest of Sicily. In the West, it may have first been worked into long, thin forms in Sicily around the 12th century, as the Tabula Rogeriana of Muhammad al-Idrisi attested, reporting some traditions about the Sicilian kingdom. The popularity of spaghetti spread throughout Italy after the establishment of spaghetti factories in the 19th century, enabling the mass production of spaghetti for the Italian market. In the United States around the end of the 19th century, spaghetti was offered in restaurants as "Spaghetti Italienne" (which likely consisted of noodles cooked past "al dente", and a mild tomato sauce flavored with

title: Spaghetti content: easily found spices and vegetables such as cloves, bay leaves, and garlic) and it was not until decades later that it came to be commonly prepared with oregano or basil. Spaghetti is made from ground grain (flour) and water. Whole-wheat and multigrain spaghetti are also available. At its simplest, spaghetti can be formed using no more than a rolling pin and a knife. A home pasta machine simplifies the rolling and makes the cutting more uniform. Fresh spaghetti would normally be cooked within hours of being formed. Commercial versions of 'fresh' spaghetti are manufactured. The bulk of dried spaghetti is

title: Spaghetti content: produced in factories using auger extruders. While essentially simple, the process requires attention to detail to ensure that the mixing and kneading of the ingredients produces a homogeneous mix, without air bubbles. The forming dies have to be water cooled to prevent spoiling of the pasta by overheating. Drying of the newly formed spaghetti has to be carefully controlled to prevent strands sticking together, and to leave it with sufficient moisture so that it is not too brittle. Packaging for protection and display has developed from paper wrapping to plastic bags and boxes. Fresh or dry spaghetti is cooked in

title: Spaghetti content: a large pot of salted, boiling water and then drained in a colander (). In Italy, spaghetti is generally cooked "al dente" (Italian for "to the tooth"), fully cooked but still firm to the bite. It may also be cooked to a softer consistency. "Spaghettoni" is a thicker spaghetti which takes more time to cook. "Spaghettini" is a thinner form which takes less time to cook. "Capellini" is a very thin form of spaghetti (it is also called "angel hair spaghetti" or "angel hair pasta") which cooks very quickly. Utensils used in spaghetti preparation include the spaghetti scoop and spaghetti

title: Spaghetti content: tongs. An emblem of Italian cuisine, spaghetti is frequently served with tomato sauce, which may contain various herbs (especially oregano and basil), olive oil, meat, or vegetables. Other spaghetti preparations include amatriciana or carbonara. Grated hard cheeses, such as Pecorino Romano, Parmesan and Grana Padano, are often sprinkled on top. In some countries, spaghetti is sold in cans/tins with sauce. In the United States, it is sometimes served with chili con carne. Unlike in Italy, abroad spaghetti is often served with Bolognese sauce. In the Philippines, an immensely popular variant is the Filipino spaghetti, which is distinctively sweet with the

title: Spaghetti content: tomato sauce sweetened with banana ketchup or sugar. It typically uses a large amount of "giniling" (ground meat), sliced hotdogs, and cheese. The dish dates back to the period between the 1940s to the 1960s. During the American Commonwealth Period, a shortage of tomato supplies in the Second World War forced the development of the banana ketchup. Spaghetti was introduced by the Americans and was tweaked to suit the local Filipino predilection for sweet dishes. "Sapaketti phat khi mao" (Spaghetti fried drunken noodle style) is a popular dish in Thai cuisine. By 1955, annual consumption of spaghetti in Italy doubled

By that year, Italy produced 1,432,990 tons of spaghetti, of which 74,000 were exported, and had a production capacity of 3 million tons. Pasta provides carbohydrates, along with some protein, iron, dietary fiber, potassium and B vitamins. Pasta prepared with whole wheat grain provides more dietary fiber than that prepared with degermed flour. The world record for the largest bowl of spaghetti was set in March 2009 and reset in March 2010 when a Buca di Beppo restaurant in Garden Grove, California, filled a swimming pool with more than of pasta.

It is located in the civil parish of Colares, in the municipality of Sintra, situated on a promontory that juts out into the ocean, made up of granite boulders and interspersed limestone. It is a third-order lighthouse, which originally began operating in 1772. It was the first new purpose-built lighthouse to be constructed in the country: the older lighthouses in existence at that time, were constructed on existing platforms or from

The initiative to construct the lighthouse came from the "Junta Geral da Fazenda do Reino" on 1 February 1758, in an order to construct six lighthouses strategically throughout the country to assist navigation. Cabo da Roca lighthouse began operating in 1772, becoming the third oldest lighthouse along the Portuguese coast. During the management of civil engineer Gaudêncio Fontana (1843), the lighthouse was updated with a new rotation platform, comprising sixteen Argand lamps with parabolic reflectors. Yet, by 1865, there were critics of the system, noting the inefficiency of the lighthouse. Over time this was addressed by the installation

Instruction: Utilizing the given image, obtain documents that respond to the following question:

title: "Confederation Bridge" content: Confederation Bridge The Confederation Bridge () spans the Abegweit Passage of Northumberland Strait. It links Prince Edward Island with mainland New Brunswick, Canada. Before its official naming, Prince Edward Islanders often referred to the bridge as the "Fixed Link". Construction took place from October 1993 to May 1997 and cost C$1.3 billion. The bridge opened on May 31, 1997. The bridge is a two-lane toll bridge that carries the Trans-Canada Highway between Borden-Carleton, Prince Edward Island (at Route 1) and Cape Jourimain, New Brunswick (at Route 16). It is a multi-span balanced cantilever bridge with a post-tensioned concrete box girder

title: "Confederation Bridge" content: structure. Most of the curved bridge is above water with a navigation span for ship traffic. The bridge rests on 62 piers, of which the 44 main piers are apart. The bridge is wide. The speed limit on the bridge is but can vary with wind and weather conditions. When travelling at the speed limit, it takes about 12 minutes to cross the bridge. Tolls only apply when leaving Prince Edward Island (when traveling westbound). The toll rates are $47.00 for a two-axle automobile and $8.00 for each additional axle. Motorcycles are charged $18.50. While pedestrians and cyclists are not

title: "Confederation Bridge" content: permitted to cross the bridge, a shuttle service is available. Before 2006, the shuttle was free and since January 1, 2015, the service has charged $4.25 per pedestrian or $8.75 per cyclist when leaving Prince Edward Island. The other major Northumberland Strait crossing, Wood Islands Ferry from Wood Islands, Prince Edward Island to Caribou, Nova Scotia, charges when leaving Prince Edward Island. Other ferry fares include $20.00 per adult pedestrian, $40.00 per motorcycle, and $20.00 per bicycle. Travellers, whether entering the island by bridge and leaving by ferry or "vice versa" only pay for leaving the island. Various proposals for

title: "Confederation Bridge" content: a fixed link across the Northumberland Strait can be traced as far back as the 1870s when the province's railway system was developed. Subsequent proposals arose during federal elections in the late 1950s and early 1960s. The ebb and flow of public support for a fixed link was indirectly tied to the varying levels of federal investment in ferry and steamship connections to the province over the years, finally culminating in a proposal in the mid-1980s which resulted in the current bridge being constructed. As a part of Prince Edward Island's admission into the Dominion of Canada in 1873, the

title: "Confederation Bridge" content: Canadian government was obligated to provide... Following Confederation, early steamship services across Northumberland Strait connected the Island ports of Charlottetown and Georgetown with railway facilities at Pictou, Nova Scotia. Similar services operated from Summerside connected with railway facilities at Shediac, New Brunswick. The most direct route across the Northumberland Strait, however, was at the 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

title: "Confederation Bridge" content: 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 Tormentine, NB). The privately owned New Brunswick and Prince Edward Island Railway from Sackville, New Brunswick to Cape Tormentine was purchased by the federal government and an order was made with a shipyard in England for an icebreaking railcar ferry, to be called the "Prince Edward Island". Ports were

title: "Confederation Bridge" content: developed at Carleton Point, several kilometres west of Cape Traverse, and the existing harbour at Cape Tormentine; the new port at Carleton Point would be named Borden in honour of Prime Minister Sir Robert Borden. The new ferry entered service in 1915 and operated on the former steamship routes until port facilities were opened in October 1917. Automobile service was added in 1938 and other vessels followed as the ferry service expanded in the post-war years. This ferry service was initially the responsibility of Canadian Government Railways (1917–1918) and later Canadian National Railway (1918–1983), then a CNR subsidiary CN Marine

title: "Confederation Bridge" content: (1977–1986). In 1986, CN Marine was renamed when all federal government ferry services in Atlantic Canada were transferred to the new Crown corporation Marine Atlantic. Discussion of a fixed link can be traced to George Howlan, who called for construction of a railway tunnel beneath Abegweit Passage at the same time as the Prince Edward Island Railway was being built across the province in the 1870s. Howlan also raised the issue as a member of the provincial Legislative Assembly, and in March 1891, as a Senator and member of a delegation to meetings on the subject, conducted at the British

title: "Confederation Bridge" content: Parliament. The idea lost favour following his death in 1901. Talk of a fixed link was revived in the 1950s and 1960s, coinciding with federal election campaigns. 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 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

title: "Confederation Bridge" content: tenders for a $148 million fixed link featuring a tunnel/causeway/bridge. Approach roads and railway lines were 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

title: "Confederation Bridge" content: a gap in such a causeway would be in excess of , powerful enough to counter most commercial ships and to sweep away boulders the size of houses. Consideration of a fixed link was renewed in the 1980s by an unsolicited proposal from a Nova Scotia businessman. The federal government favoured the construction of a fixed link chiefly because of the rising costs of providing ferry service (a constitutional requirement dating from PEI's accession to Confederation) and the increasing deficits being incurred by the railway system on PEI (run as part of Canadian National, then a Crown corporation). The federal

title: "Confederation Bridge" content: government proposed to provide a fixed subsidy for the construction and operation of a fixed link, in return for the province agreeing to the abandonment of the ferry service and the railway system. Following the election of the Progressive Conservative government of Brian Mulroney, with its agenda for regional development through so-called "mega-projects," Public Works Canada called for formal proposals in 1987 and received three offers. These proposals included a tunnel, a bridge, and a combined tunnel-causeway-bridge. These developments sparked an extremely divisive debate on the Island, and Premier Joe Ghiz promised a plebiscite to gauge public support, which was

title: "Confederation Bridge" content: held on January 18, 1988. During the plebiscite debate, the anti-link group "Friends of the Island" cited potential ecological damage from the construction, as well as concerns about the impact on Prince Edward Island's lifestyle in general, and noted that the "mega-project" model has had limited success in other areas of the world, and rarely enriched the local population. The "Friends of the Island" believed that a fixed link was being pressured by a federal government not willing to shoulder the cost of constitutional obligations for funding an efficient ferry service, and that a link would be built largely for

title: "Confederation Bridge" content: on December 2, 1992; the developer being required to privately finance all construction through bond markets. Shareholders of Strait Crossing Development Inc. include: As mentioned, the Schedule to the Prince Edward Island Terms of Union in the Constitution of Canada required steamship service to connect the Island's railway system with that of mainland North America. A dedicated ferry service replaced the steamships in 1917 but no changes were made to the constitution. The fixed crossing, however, required a constitutional amendment (see Amendments to the Constitution of Canada). The Constitution Amendment Proclamation, 1993 (Prince Edward Island) dealt with this issue, as

title: "Confederation Bridge" content: well as the issue of tolls on the crossing. It made clear that the government (or a private body) could charge a toll (an essential part of the government's financing plans) for the crossing without violating the terms of union: The construction, which was carried out by a construction joint venture of Ballast Nedam, GTMI (Canada), Northern Construction and Strait Crossing Inc., started in the fall of 1993, beginning with preparation of staging facilities. Bridge components were built year-round from 1994 to the summer of 1996, and placement of components began in the fall of 1994 until the fall of

title: "Confederation Bridge" content: 1996. Approach roads, toll plazas, and final work on the structure continued until the spring of 1997, at an estimated total cost of $1 billion. All bridge components were constructed on land, in purpose-built staging yards located on the shoreline at Amherst Head, fronting on Borden Harbour just east of the town and ferry docks, and an inland facility located at Bayfield, New Brunswick about west of Cape Tormentine. The Amherst Head staging facility was where all large components were built, including the pier bases, ice shields, main spans, and drop-in spans. The Bayfield facility was used to construct components

title: "Confederation Bridge" content: for the near-shore bridges which were linked using a launching truss extending over shallow waters almost from the New Brunswick shore, and from the Prince Edward Island shore. Extremely durable high-grade concrete and reinforcing steel were used throughout construction of the pre-cast components, with the estimated lifespan of the bridge being in excess of 100 years. Their sheer size and weight required strengthening of the soil base during the design and preparation work for the Amherst Head staging facility, as well as the use of a crawler transport system to move pieces from fabrication to storage, and onto a nearby

title: "Confederation Bridge" content: pier. 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. HLV "Svanen" was custom-built for use on the Great Belt Bridge in the early 1990s, Denmark's largest construction project, and was modified at a French shipyard before working on the Northumberland Strait Crossing Project.

The President of Ireland, Mary McAleese, during a state visit to Canada in 1998, referred to the bridge as the "Span of Green Gables". After completing the structure on November 19, 1996, SCI worked throughout the winter, paving the bridge deck, placing protective walls which act as wind barriers, placing bridge deck and navigational lighting, constructing the Borden-Carleton toll plaza, and finishing the New Brunswick and Prince Edward Island approach roads. In separate construction, the federal and provincial governments built a new commercial and tourist development on the abandoned CN rail yards

title: "Confederation Bridge" content: in Borden-Carleton, with phase I of this facility opening in spring 1997 as "Gateway Village". New Brunswick has never received similar federal support to improve the economy of Cape Tormentine, which has become a shadow of its former role in PEI transportation history, although in recent years a new eco-tourist and visitor centre was opened on Jourimain Island near the western end of the bridge. The official opening for the bridge took place on May 31, 1997, with the first traffic crossing at approximately 5:00 p.m. ADT following a nationally televised ceremony which aired on CBC and included a sailpast

title: "Confederation Bridge" content: of the schooner "Bluenose II" and several Canadian Coast Guard ships, a flyover by the "Snowbirds", and an emotional farewell to the beloved ferries which made their final crossings that evening. It is estimated that almost 75,000 people participated in a "Bridge Walk" and "Bridge Run" during the hours immediately prior to the opening for traffic. In the days following the opening of the bridge, ferry operator Marine Atlantic disposed of its four vessels. The ferry terminals and docks in both ports were removed over the summer of 1997. The bridge is operated by Strait Crossing Bridge Limited (SCBL), a

title: "Confederation Bridge" content: subsidiary of the Strait Crossing Development Inc. consortium which built the structure. SCBL will privately manage, maintain, and operate the bridge until 2032, when these operations will transfer to the Government of Canada. The Government of Canada agreed to pay about $44 million a year for 33 years to Strait Crossing Development Inc., this being the subsidy which was formerly paid to Marine Atlantic to cover operating losses of the ferry system. These payments are in effect a mortgage and are being used by the developer to pay off construction costs. In 2032, the bridge's ownership will revert to the

title: "Confederation Bridge" content: the complete replacement of all bridge deck lighting cutting into profits. Toll revenues have fallen over 30% since the bridge opened, largely because of declining tourism traffic and domestic travel and currently range from $25 to $30 million annually. After expenses in 2003, the consortium received a year-end dividend of $2.6 million. The number of tourists visiting Prince Edward Island increased from 740,000 in 1996 (the year before the bridge opened) to 1,200,000 in 1997, but this dropped back to about 900,000 visitors annually. As a way of further promoting the island's new accessibility, the province issued vehicle licence plates

title: Calgary content: Calgary Calgary () is a city in the Canadian province of Alberta. It is situated at the confluence of the Bow River and the Elbow River in the south of the province, in an area of foothills and prairie, about east of the front ranges of the Canadian Rockies. The city anchors the south end of what Statistics Canada defines as the "Calgary–Edmonton Corridor". The city had a population of 1,239,220 in 2016, making it Alberta's largest city and Canada's third-largest municipality. Also in 2016, Calgary had a metropolitan population of 1,392,609, making it the fourth-largest census metropolitan area (CMA)

title: Calgary content: fourth most liveable city in the world in their Global Liveability Ranking. Calgary was named after Calgary on the Isle of Mull, Scotland. In turn, the name originates from a compound of "kald" and "gart", similar Old Norse words, meaning "cold" and "garden", likely used when named by the Vikings who inhabited the Inner Hebrides. Alternatively, the name might be Gaelic "Cala ghearraidh", meaning "beach of the meadow (pasture)", or Gaelic for either "clear running water" or "bay farm". The indigenous peoples of Southern Alberta referred to the Calgary area as "elbow", in reference to the sharp bend made by

title: Calgary content: at the elbow" or "Otoskwunee" meaning "elbow". In the Tsuut'ina (Sarcee) language, the area is known as "Kootsisáw" meaning "elbow". In the Slavey language, the area was known as "Klincho-tinay-indihay" meaning "many horse town", referring to the Calgary Stampede and the city's settler heritage. There have been several attempts to revive the indigenous names of Calgary. In response to the Truth and Reconciliation Commission, local post-secondary institutions have adopted "official acknowledgements" of indigenous territory using the Blackfoot name of the City, "Mohkínstsis." In 2017, the Stoney Nakoda sent an application to the Government of Alberta, to rename Calgary as "Wichispa

title: Calgary content: Oyade" meaning "elbow town", however this has been challenged by the Piikani Blackfoot. The Calgary area was inhabited by pre-Clovis people whose presence has been traced back at least 11,000 years. The area has been inhabited by the Niitsitapi (Blackfoot Confederacy Confederacy; Siksika, Kainai, Piikani), îyârhe Nakoda, the Tsuut'ina First Nations peoples and Métis Nation, Region 3. As Mayor Naheed Nenshi ("A'paistootsiipsii; Iitiya") describes, "There have always been people here. In Biblical times there were people here. For generations beyond number, people have come here to this land, drawn here by the water. They come here to hunt and fish;

title: Calgary content: to trade; to live; to love; to have great victories; to taste bitter disappointment; but above all to engage in that very human act of building community." In 1787, cartographer David Thompson spent the winter with a band of Peigan encamped along the Bow River. He was a Hudson's Bay Company trader and the first recorded European to visit the area. John Glenn was the first documented European settler in the Calgary area, in 1873. In 1875, the site became a post of the North-West Mounted Police (now the Royal Canadian Mounted Police or RCMP). The NWMP detachment was assigned

title: Calgary content: "The City of Calgary" in what was then the North-West Territories. The Calgary Police Service was established in 1885 and assumed municipal, local duties from the NWMP. The Calgary Fire of 1886 occurred on November 7, 1886. Fourteen buildings were destroyed with losses estimated at $103,200. Although no one was killed or injured, city officials drafted a law requiring all large downtown buildings to be built with Paskapoo sandstone, to prevent this from happening again. After the arrival of the railway, the Dominion Government started leasing grazing land at minimal cost (up to for one cent per acre per year).

title: Calgary content: As a result of this policy, large ranching operations were established in the outlying country near Calgary. Already a transportation and distribution hub, Calgary quickly became the centre of Canada's cattle marketing and meatpacking industries. By the late 19th century, the Hudson's Bay Company (HBC) expanded into the interior and established posts along rivers that later developed into the modern cities of Winnipeg, Calgary and Edmonton. In 1884, the HBC established a sales shop in Calgary. The HBC also built the first of the grand "original six" department stores in Calgary in 1913, the others that followed are Edmonton, Vancouver,

title: Calgary content: Victoria, Saskatoon, and Winnipeg. Between 1896 and 1914 settlers from all over the world poured into the area in response to the offer of free "homestead" land. Agriculture and ranching became key components of the local economy, shaping the future of Calgary for years to come. The world-famous Calgary Stampede, still held annually in July, was started by four wealthy ranchers as a small agricultural show in 1912. It is now known as the "greatest outdoor show on earth". Calgary experienced Alberta's first oil boom when Calgary Petroleum Products Co found oil just southwest of the city at Turner Valley

title: Calgary content: in 1914. Western Canada's first commercial oilfield boomed again in 1924 and 1936 and by WWII the Turner Valley oilfield was producing more than 95 per cent of the oil in Canada. As a result, major oil companies searched elsewhere in Alberta and in 1947 Imperial Oil discovered new reserves near Leduc, south of Edmonton. But Calgary was already the centre of Alberta oil and the new discovery caused the city to boom again. Calgary's economy grew when oil prices increased with the Arab Oil Embargo of 1973. The population increased by 272,000 in the eighteen years between 1971 (403,000)

title: Calgary content: these Games essentially put the city on the world stage. Thanks in part to escalating oil prices, the economy in Calgary and Alberta was booming until the end of 2009, and the region of nearly 1.1 million people was home to the fastest growing economy in the country. While the oil and gas industry comprise an important part of the economy, the city has invested a great deal into other areas such as tourism and high-tech manufacturing. Over 3.1 million people now visit the city annually for its many festivals and attractions, especially the Calgary Stampede. The nearby mountain resort

title: Calgary content: towns of Banff, Lake Louise, and Canmore are also becoming increasingly popular with tourists, and are bringing people into Calgary as a result. Other modern industries include light manufacturing, high-tech, film, e-commerce, transportation, and services. Widespread flooding throughout southern Alberta, including on the Bow and Elbow rivers, forced the evacuation of over 75,000 city residents on June 21, 2013, and left large areas of the city, including downtown, without power. Calgary is located at the transition zone between the Canadian Rockies foothills and the Canadian Prairies. The city lies within the foothills of the Parkland Natural Region and the Grasslands

The Bow River is the larger and it flows from the west to the south. The Elbow River flows northwards from the south until it converges with the Bow River at the historic site of Fort Calgary near downtown. Since the climate of the region is generally dry, dense vegetation occurs naturally only in the river valleys, on some north-facing slopes, and within Fish Creek Provincial Park. The City of

Lying beyond these, and usually separated from one another by highways, are suburban communities including Evergreen, Somerset, Auburn Bay Country Hills, Sundance, Riverbend, and McKenzie Towne. In all, there are over 180 distinct neighbourhoods within the city limits. Several of Calgary's neighbourhoods were initially separate municipalities that were annexed by the city as

Currently, the most stable and secure part of the sea otter's range is Russia. Before the 19th century, around 20,000 to 25,000 sea otters lived near the Kuril Islands, with more near Kamchatka and the Commander Islands. After the years of the Great Hunt, the population in these areas, currently part of Russia, was only 750.

It is a small deciduous tree or shrub reaching a height of , usually with thorny branches. The leaves are shiny-green, ovate-acute, long and wide, with three conspicuous veins at the base, and a finely toothed margin. The flowers are small, wide, with five inconspicuous yellowish-green petals. The fruit is an edible oval drupe deep; when immature it is smooth-green, with the consistency and taste of an apple,

For the species name he used a different name, as tautonyms (repetition of exactly the same name in the genus and species) are not permitted in botanical naming. However, because of Miller's slightly different spelling, the combination the earlier species name (from Linnaeus) with the new genus, "Ziziphus zizyphus", is "not" a tautonym, and was therefore permitted as a botanical name. This combination was made by Hermann Karsten in 1882. In 2006, a proposal was made to suppress the

title: Jujube content: name "Ziziphus zizyphus" in favor of "Ziziphus jujuba", and this proposal was accepted in 2011. "Ziziphus jujuba" is thus the correct scientific name for this species. In Arabic-speaking regions the jujube and alternatively the species "Z. lotus" are closely related to the lote-trees (sing. "sidrah", pl. "sidr") which are mentioned in the Quran, while in Palestine it is rather the species "Z. spina-christi" that is called "sidr". Varieties of jujube include Li, Lang, Sherwood, Silverhill, So, Shui Men and GA 866. Jujube was domesticated in south Asia by 9000 BC. Over 400 cultivars have been selected. The tree tolerates a

Rather, "ber" is used for three other cultivated or wild species, e.g., "Z. spina-christi", "Z. mauritiana", and "Z. nummularia" in Pakistan and parts of India and is eaten both fresh and dried. The Arabic name "sidr" is used for "Ziziphus" species other than "Z. jujuba". Traditionally in India, the fruit is dried in the sun and the hard nuts are removed.

Given the distances between the vertices of a tetrahedron the volume can be computed using the Cayley–Menger determinant: where the subscripts represent the vertices and "d" is the pairwise distance between them – i.e., the length of the edge connecting the two vertices. A negative value of the determinant means that a tetrahedron cannot be constructed with the given distances. This formula, sometimes called Tartaglia's formula, is essentially due to the painter Piero della Francesca in the 15th century, as a three dimensional analogue of

A line segment joining a vertex of a tetrahedron with the centroid of the opposite face is called a "median" and a line segment joining the midpoints of two opposite edges is called a "bimedian" of the tetrahedron. Hence there are four medians and three bimedians in a tetrahedron. These seven line segments are all concurrent at a point called the "centroid" of the tetrahedron. In addition the four medians are divided in a 3:1 ratio by the centroid (see Commandino's theorem). The centroid of a tetrahedron is the midpoint

title: Tetrahedron content: Putting any of the four vertices in the role of "O" yields four such identities, but at most three of them are independent: If the "clockwise" sides of three of them are multiplied and the product is inferred to be equal to the product of the "counterclockwise" sides of the same three identities, and then common factors are cancelled from both sides, the result is the fourth identity. Three angles are the angles of some triangle if and only if their sum is 180° (π radians). What condition on 12 angles is necessary and sufficient for them to be the

title: Tetrahedron content: 12 angles of some tetrahedron? Clearly the sum of the angles of any side of the tetrahedron must be 180°. Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8. The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional. Let be the points of a
