Pulsar. on August 6, 1967 from a newly commissioned radio telescope that she helped build. Initially dismissed as radio interference by her supervisor, Antony Hewish, developer of the telescope, the fact that the signals always appeared at the same declination and right ascension soon ruled out a terrestrial source. On November 28, 1967, Bell and Hewish using a fast recorder resolved the signals as a series of pulses, evenly spaced every 1.33 seconds. No astronomical object of this nature had ever been observed before. On December 21, Bell discovered a second pulsar, quashing speculation that these might be signals beamed at.

Pulsar. name for intelligent beings of extraterrestrial origin).It was not until a second pulsating source was discovered in a different part of the sky that the "LGM hypothesis" was entirely abandoned. Their pulsar was later dubbed CP 1919, and is now known by a number of designators including PSR B1919+21 and PSR J1921+2153. Although CP 1919 emits in radio wavelengths, pulsars have subsequently been found to emit in visible light, X-ray, and gamma ray wavelengths.The word "pulsar" first appeared in print in 1968: The existence of neutron stars was first proposed by Walter Baade and Fritz Zwicky in 1934, when they.

Pulsar. argued that a small, dense star consisting primarily of neutrons would result from a supernova. Based on the idea of magnetic flux conservation from magnetic main sequence stars, Lodewijk Woltjer proposed in 1964 that such neutron stars might contain magnetic fields as large as 1014 to 1016 gausses (=1010 to 1012 teslas). In 1967, shortly before the discovery of pulsars, Franco Pacini suggested that a rotating neutron star with a magnetic field would emit radiation, and even noted that such energy could be pumped into a supernova remnant around a neutron star, such as the Crab Nebula. After the discovery.

Pulsar. of the first pulsar, Thomas Gold independently suggested a rotating neutron star model similar to that of Pacini, and explicitly argued that this model could explain the pulsed radiation observed by Bell Burnell and Hewish. In 1968, Richard V. E. Lovelace with collaborators discovered period formula_1 ms of the Crab Nebula pulsar using Arecibo Observatory.The discovery of the Crab pulsar provided confirmation of the rotating neutron star model of pulsars. The Crab pulsar 33-millisecond pulse period was too short to be consistent with other proposed models for pulsar emission. Moreover, the Crab pulsar is so named because it is located.

Pulsar. as a system of Galactic clocks. Disturbances in the clocks will be measurable at Earth. A disturbance from a passing gravitational wave will have a particular signature across the ensemble of pulsars, and will be thus detected.## Significant pulsars.The pulsars listed here were either the first discovered of its type, or represent an extreme of some type among the known pulsar population, such as having the shortest measured period. The first radio pulsar "CP 1919" (now known as PSR B1919+21), with a pulse period of 1.337 seconds and a pulse width of 0.04-second, was discovered in 1967. The first binary.

Huis Ten Bosch (theme park). Is a theme park in Sasebo, Nagasaki, Japan, which recreates the Netherlands by displaying life-sized copies of old Dutch buildings. The name "Huis Ten Bosch" translates into English as "House at the Woods/Forest". It is named after Huis ten Bosch in The Hague, one of the three official residences of the Dutch Royal Family.## Overview.The park features many Dutch-style buildings such as hotels, villas, theatres, museums, shops and restaurants, along with canals, windmills, amusement rides, and a park planted in seasonal flowers.

Jigsaw puzzle. A jigsaw puzzle is a tiling puzzle that requires the assembly of often irregularly shaped interlocking and mosaiced pieces, each of which typically has a portion of a picture. When assembled, the puzzle pieces produce a complete picture.In the 18th century, jigsaw puzzles were created by painting a picture on a flat, rectangular piece of wood, then cutting it into small pieces. Despite the name, a jigsaw was never used. John Spilsbury, a London cartographer and engraver, is credited with commercialising jigsaw puzzles around 1760. They have since come to be made primarily of cardboard.Typical images on jigsaw puzzles include.

New World oriole. New World orioles are a group of birds in the genus Icterus of the blackbird family. Unrelated to Old World orioles of the family Oriolidae, they are strikingly similar in size, diet, behavior, and strongly contrasting plumage. As a result, the two have been given the same vernacular name.Males are typically black and vibrant yellow or orange with white markings, females and immature birds duller. They molt annually. New World orioles are generally slender with long tails and a pointed bill. They mainly eat insects, but also enjoy nectar and fruit. The nest is a woven, elongated pouch. Species nesting.

Wolf. habitat.Wolves occur across Eurasia and North America. However, deliberate human persecution because of livestock predation and fear of attacks on humans has reduced the wolf's range to about one-third of its historic range; the wolf is now extirpated (locally extinct) from much of its range in Western Europe, the United States and Mexico, and completely in Ireland, the United Kingdom, and Japan. In modern times, the wolf occurs mostly in wilderness and remote areas. The wolf can be found between sea level and 3000 (m). Wolves live in forests, inland wetlands, shrublands, grasslands (including Arctic tundra), pastures, deserts, and rocky.

Wolf. are nocturnal predators. During the winter, a pack will commence hunting in the twilight of early evening and will hunt all night, traveling tens of kilometres. Sometimes hunting large prey occurs during the day. During the summer, wolves generally tend to hunt individually, ambushing their prey and rarely giving pursuit.When hunting large gregarious prey, wolves will try to isolate an individual from its group. If successful, a wolf pack can bring down game that will feed it for days, but one error in judgement can lead to serious injury or death. Most large prey have developed defensive adaptations and behaviours.

Dacrydium cupressinum. Dacrydium cupressinum, commonly known as rimu, is a large evergreen coniferous tree endemic to the forests of New Zealand. It is a member of the southern conifer group, the podocarps. The former name "red pine" has fallen out of common use.## Distribution.Rimu grows throughout New Zealand, in the North Island, South Island and Stewart Island/Rakiura. This species is common in lowland and montane forest. Although the largest concentration of trees is now found on the West Coast of the South Island, the biggest trees tend to be in mixed podocarp forest near Taupo (e.g., Pureora, Waihaha, and Whirinaki Forests). A.

However, many of New Zealand's original stands of rimu have been destroyed, and recent government policies forbid the felling of rimu in public forests, though allowing limited logging on private land. "Pinus radiata" has now replaced rimu in most industries, although rimu remains popular for the production of high quality wooden furniture. There is also limited recovery of stump and root wood, from trees felled many years before, for use in making bowls and other wood turned objects.The inner bark can also be used to treat burns.

It is attractive at all growth stages, usually quite narrow when young, then developing into a broader tree with weeping branches before finally progressing to its more upright adult form. While rimu does exhibit some variation in the wild, garden cultivars are largely unknown, except for one recent introduction, 'Charisma', which is a compact, golden-foliaged form.

Sea otter. The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters typically weigh between 14 and 45 (kg), making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living exclusively in the ocean.The sea otter inhabits nearshore environments, where it dives to the sea floor to.

Sea otter. were once estimated at 150,000–300,000, were hunted extensively for their fur between 1741 and 1911, and the world population fell to 1,000–2,000 individuals living in a fraction of their historic range. A subsequent international ban on hunting, sea otter conservation efforts, and reintroduction programs into previously populated areas have contributed to numbers rebounding, and the species occupies about two-thirds of its former range. The recovery of the sea otter is considered an important success in marine conservation, although populations in the Aleutian Islands and California have recently declined or have plateaued at depressed levels. For these reasons, the sea otter.

Sea otter. remains classified as an endangered species.## Evolution.The sea otter is the heaviest (the giant otter is longer, but significantly slimmer) member of the family Mustelidae, a diverse group that includes the 13 otter species and terrestrial animals such as weasels, badgers, and minks. It is unique among the mustelids in not making or burrows, in having no functional anal scent glands, and in being able to live its entire life without leaving the water. The only living member of the genus "Enhydra", the sea otter is so different from other mustelid species that, as recently as 1982, some scientists believed.

Sea otter. spread east to the Aleutian Islands, mainland Alaska, and down the North American coast. In comparison to cetaceans, sirenians, and pinnipeds, which entered the water approximately 50, 40, and 20 million years ago, respectively, the sea otter is a relative newcomer to a marine existence. In some respects, though, the sea otter is more fully adapted to water than pinnipeds, which must haul out on land or ice to give birth. The full genome of the northern sea otter ("Enhydra lutris kenyoni") was sequenced in 2017 and may allow for examination of the sea otter's evolutionary divergence from terrestrial mustelids.##.

Sea otter. Taxonomy.The first scientific description of the sea otter is contained in the field notes of Georg Steller from 1751, and the species was described by Carl Linnaeus in his landmark 1758 10th edition of "Systema Naturae". Originally named "Lutra marina", it underwent numerous name changes before being accepted as "Enhydra lutris" in 1922. The generic name "Enhydra", derives from the Ancient Greek "en"/εν "in" and "hydra"/ύδρα "water", meaning "in the water", and the Latin word "lutris", meaning "otter". It was formerly sometimes referred to as the "sea beaver".## Subspecies.Three subspecies of the sea otter are recognized with distinct geographical distributions.

Sea otter. Description.The sea otter is one of the smallest marine mammal species, but it is the heaviest mustelid. Male sea otters usually weigh 22 to 45 (kg) and are 1.2 to 1.5 (m) in length, though specimens up to 54 (kg) have been recorded. Females are smaller, weighing 14 to 33 (kg) and measuring 1.0 to 1.4 (m) in length. For its size, the male otter's baculum is very large, massive and bent upwards, measuring 150 (mm) in length and 15 (mm) at the base.Unlike most other marine mammals, the sea otter has no blubber and relies on its exceptionally thick.

Sea otter. fur to keep warm. With up to 150000 (/cm2), its fur is the densest of any animal. The fur consists of long, waterproof guard hairs and short underfur; the guard hairs keep the dense underfur layer dry. There is an air compartment between the thick fur and the skin where air is trapped and heated by the body. Cold water is kept completely away from the skin and heat loss is limited. However, this air compartment can be disadvantageous because as the sea otter dives deeper into the water column, the air compartment compresses and heat needed to warm the.

Sea otter. the urchin's shell.The sea otter's use of rocks when hunting and feeding makes it one of the few mammal species to use tools. To open hard shells, it may pound its prey with both paws against a rock on its chest. To pry an abalone off its rock, it hammers the abalone shell using a large stone, with observed rates of 45 blows in 15 seconds. Releasing an abalone, which can cling to rock with a force equal to 4,000 times its own body weight, requires multiple dives.## Social structure.Although each adult and independent juvenile forages alone, sea otters tend.

Sea otter. to rest together in single-sex groups called "rafts". A raft typically contains 10 to 100 animals, with male rafts being larger than female ones. The largest raft ever seen contained over 2000 sea otters. To keep from drifting out to sea when resting and eating, sea otters may wrap themselves in kelp.A male sea otter is most likely to mate if he maintains a breeding territory in an area that is also favored by females. As autumn is the peak breeding season in most areas, males typically defend their territory only from spring to autumn. During this time, males patrol.

Sea otter. jaws during copulation. Visible scars are often present on females from this behavior.Births occur year-round, with peaks between May and June in northern populations and between January and March in southern populations. Gestation appears to vary from four to twelve months, as the species is capable of delayed implantation followed by four months of pregnancy. In California, sea otters usually breed every year, about twice as often as those in Alaska.Birth usually takes place in the water and typically produces a single pup weighing 1.4 to 2.3 (kg). Twins occur in 2% of births; however, usually only one pup survives.

Sea otter. At birth, the eyes are open, ten teeth are visible, and the pup has a thick coat of baby fur. Mothers have been observed to lick and fluff a newborn for hours; after grooming, the pup's fur retains so much air, the pup floats like a cork and cannot dive. The fluffy baby fur is replaced by adult fur after about 13 weeks.Nursing lasts six to eight months in Californian populations and four to twelve months in Alaska, with the mother beginning to offer bits of prey at one to two months.

Mothers have been known to carry their pups for days after the pups' deaths.Females become sexually mature at around three or four years of age and males at around five; however, males often do not successfully breed until a few years later. A captive male sired offspring at age 19. In the wild, sea otters live to a maximum age of 23 years, with lifespans ranging from 10 to 15 years for males and 15–20 years for.

Sea otter. females. Several captive individuals have lived past 20 years, and a female at the Seattle Aquarium died at the age of 28 years. Sea otters in the wild often develop worn teeth, which may account for their apparently shorter lifespans.## Population and distribution.Sea otters live in coastal waters 15 to 23 (m) deep, and usually stay within a kilometre ( mi) of the shore. They are found most often in areas with protection from the most severe ocean winds, such as rocky coastlines, thick kelp forests, and barrier reefs. Although they are most strongly associated with rocky substrates, sea otters.

Sea otter. can also live in areas where the sea floor consists primarily of mud, sand, or silt. Their northern range is limited by ice, as sea otters can survive amidst drift ice but not land-fast ice. Individuals generally occupy a home range a few kilometres long, and remain there year-round.The sea otter population is thought to have once been 150,000 to 300,000, stretching in an arc across the North Pacific from northern Japan to the central Baja California Peninsula in Mexico. The fur trade that began in the 1740s reduced the sea otter's numbers to an estimated 1,000 to 2,000 members.

Sea otter. in 13 colonies. Hunting records researched by historian Adele Ogden place the westernmost limit of the hunting grounds off the northern Japanese island of Hokkaido and the easternmost limit off Punta Morro Hermosa about 21+1/2 (mi) south of Punta Eugenia, Baja California's westernmost headland in Mexico.In about two-thirds of its former range, the species is at varying levels of recovery, with high population densities in some areas and threatened populations in others. Sea otters currently have stable populations in parts of the Russian east coast, Alaska, British Columbia, Washington, and California, with reports of recolonizations in Mexico and Japan. Population.

Sea otter. estimates made between 2004 and 2007 give a worldwide total of approximately 107,000 sea otters.## Japan.Adele Ogden wrote in "The California Sea Otter Trade" that sea otter were hunted "from Yezo northeastward past the Kuril Group and Kamchatka to the Aleutian Chain". "Yezo" refers to the island of Hokkaido in northern Japan; the only confirmed sea otter population in Japanese territory is on the coast surrounding the town of Erimo, Hokkaido.## Russia.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,.

Sea otter. 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. By 2004, sea otters had repopulated all of their former habitat in these areas, with an estimated total population of about 27,000. Of these, about 19,000 are at the Kurils, 2,000 to 3,500 at Kamchatka and another 5,000 to 5,500 at the Commander Islands. Growth has slowed slightly, suggesting the numbers are reaching carrying capacity.## British Columbia.Along the North American coast south of Alaska, the sea otter's range is discontinuous. A remnant population.

Sea otter. survived off Vancouver Island into the 20th century, but it died out despite the 1911 international protection treaty, with the last sea otter taken near Kyuquot in 1929. From 1969 to 1972, 89 sea otters were flown or shipped from Alaska to the west coast of Vancouver Island. This population increased to over 5,600 in 2013 with an estimated annual growth rate of 7.2%, and their range on the island's west coast extended north to Cape Scott and across the Queen Charlotte Strait to the Broughton Archipelago and south to Clayoquot Sound and Tofino. In 1989, a separate colony was.

Sea otter. discovered in the central British Columbia coast. It is not known if this colony, which numbered about 300 animals in 2004, was founded by transplanted otters or was a remnant population that had gone undetected. By 2013, this population exceeded 1,100 individuals, was increasing at an estimated 12.6% annual rate, and its range included Aristazabal Island, and Milbanke Sound south to Calvert Island. In 2008, Canada determined the status of sea otters to be "special concern".## United States.## Alaska.Alaska is the central area of the sea otter's range. In 1973, the population in Alaska was estimated at between 100,000 and.

Sea otter. 125,000 animals. By 2006, though, the Alaska population had fallen to an estimated 73,000 animals. A massive decline in sea otter populations in the Aleutian Islands accounts for most of the change; the cause of this decline is not known, although orca predation is suspected. The sea otter population in Prince William Sound was also hit hard by the Exxon Valdez oil spill, which killed thousands of sea otters in 1989.## Washington.In 1969 and 1970, 59 sea otters were translocated from Amchitka Island to Washington, and released near La Push and Point Grenville. The translocated population is estimated to have.

Sea otter. declined to between 10 and 43 individuals before increasing, reaching 208 individuals in 1989. As of 2017, the population was estimated at over 2,000 individuals, and their range extends from Point Grenville in the south to Cape Flattery in the north and east to Pillar Point along the Strait of Juan de Fuca.In Washington, sea otters are found almost exclusively on the outer coasts. They can swim as close as six feet off shore along the Olympic coast. Reported sightings of sea otters in the San Juan Islands and Puget Sound almost always turn out to be North American river.

Sea otter. otters, which are commonly seen along the seashore. However, biologists have confirmed isolated sightings of sea otters in these areas since the mid-1990s.## Oregon.The last native sea otter in Oregon was probably shot and killed in 1906. In 1970 and 1971, a total of 95 sea otters were transplanted from Amchitka Island, Alaska to the Southern Oregon coast. However, this translocation effort failed and otters soon again disappeared from the state. In 2004, a male sea otter took up residence at Simpson Reef off of Cape Arago for six months. This male is thought to have originated from a colony.

Sea otter. in Washington, but disappeared after a coastal storm. On 18 February 2009, a male sea otter was spotted in Depoe Bay off the Oregon Coast. It could have traveled to the state from either California or Washington.## California.The historic population of California sea otters was estimated at 16,000 before the fur trade decimated the population, leading to their assumed extinction. Today's population of California sea otters are the descendants of a single colony of about 50 sea otters located near Bixby Creek Bridge in March 1938 by Howard G. Sharpe, owner of the nearby Rainbow Lodge on Bixby Bridge in.

Historical records revealed the Russian-American Company sneaked Aleuts into San Francisco Bay multiple times, despite the Spanish capturing or shooting them while hunting sea otters in the estuaries of San Jose, San Mateo, San Bruno and around Angel Island. The founder of Fort Ross, Ivan Kuskov, finding otters scarce on his second voyage to Bodega Bay in 1812, sent a party of Aleuts to San Francisco Bay, where they met another.

Sea otter. Russian party and an American party, and caught 1,160 sea otters in three months. By 1817, sea otters in the area were practically eliminated and the Russians sought permission from the Spanish and the Mexican governments to hunt further and further south of San Francisco. Remnant sea otter populations may have survived in the bay until 1840, when the Rancho Punta de Quentin was granted to Captain John B. R. Cooper, a sea captain from Boston, by Mexican Governor Juan Bautista Alvarado along with a license to hunt sea otters, reportedly then prevalent at the mouth of Corte Madera Creek.In.

Sea otter. the late 1980s, the USFWS relocated about 140 southern sea otters to San Nicolas Island in southern California, in the hope of establishing a reserve population should the mainland be struck by an oil spill. To the surprise of biologists, the majority of the San Nicolas sea otters swam back to the mainland. Another group of twenty swam 74 (mi) north to San Miguel Island, where they were captured and removed. By 2005, only 30 sea otters remained at San Nicolas, although they were slowly increasing as they thrived on the abundant prey around the island. The plan that authorized.

Sea otter. the translocation program had predicted the carrying capacity would be reached within five to 10 years. The spring 2016 count at San Nicolas Island was 104 sea otters, continuing a 5-year positive trend of over 12% per year. Sea otters were observed twice in Southern California in 2011, once near Laguna Beach and once at Zuniga Point Jetty, near San Diego. These are the first documented sightings of otters this far south in 30 years.When the USFWS implemented the translocation program, it also attempted, in 1986, to implement "zonal management" of the Californian population. To manage the competition between sea.

Sea otter. response to lawsuits filed by the Santa Barbara-based Environmental Defense Center and the Otter Project, on 19 December 2012 the USFWS declared that the "no otter zone" experiment was a failure, and will protect the otters re-colonizing the coast south of Point Conception as threatened species. Although abalone fisherman blamed the incursions of sea otters for the decline of abalone, commercial abalone fishing in southern California came to an end from overfishing in 1997, years before significant otter moved south of Point Conception. In addition, white abalone ("Haliotis sorenseni"), a species never overlapping with sea otter, had declined in numbers.

Sea otter. 99% by 1996, and became the first marine invertebrate to be federally listed as endangered.Although the southern sea otter's range has continuously expanded from the remnant population of about 50 individuals in Big Sur since protection in 1911, from 2007 to 2010, the otter population and its range contracted and since 2010 has made little progress. As of spring 2010, the northern boundary had moved from about Tunitas Creek to a point 2 (km) southeast of Pigeon Point, and the southern boundary has moved along the Gaviota Coast from approximately Coal Oil Point to Gaviota State Park. A toxin called.

Sea otter. microcystin, produced by a type of cyanobacteria ("Microcystis"), seems to be concentrated in the shellfish the otters eat, poisoning them. Cyanobacteria are found in stagnant water enriched with nitrogen and phosphorus from septic tank and agricultural fertilizer runoff, and may be flushed into the ocean when streamflows are high in the rainy season. A record number of sea otter carcasses were found on California's coastline in 2010, with increased shark attacks an increasing component of the mortality. Great white sharks do not consume relatively fat-poor sea otters but shark-bitten carcasses have increased from 8% in the 1980s to 15% in.

Sea otter. the 1990s and to 30% in 2010 and 2011.For southern sea otters to be considered for removal from threatened species listing, the U.S. Fish and Wildlife Service (USFWS) determined that the population should exceed 3,090 for three consecutive years. In response to recovery efforts, the population climbed steadily from the mid-20th century through the early 2000s, then remained relatively flat from 2005 to 2014 at just under 3,000. There was some contraction from the northern (now Pigeon Point) and southern limits of the sea otter's range during the end of this period, circumstantially related to an increase in lethal shark.

Sea otter. bites, raising concerns that the population had reached a plateau. However, the population increased markedly from 2015 to 2016, with the United States Geological Survey (USGS) California sea otter survey 3-year average reaching 3,272 in 2016, the first time it exceeded the threshold for delisting from the Endangered Species Act (ESA). If populations continued to grow and ESA delisting occurred, southern sea otters would still be fully protected by state regulations and the Marine Mammal Protection Act, which set higher thresholds for protection, at approximately 8,400 individuals. However, ESA delisting seems unlikely due to a precipitous population decline recorded in.

Sea otter. the spring 2017 USGS sea otter survey count, from the 2016 high of 3,615 individuals to 2,688, a loss of 25% of the California sea otter population.## Mexico.Historian Adele Ogden described sea otters are particularly abundant in "Lower California", now the Baja California Peninsula, where "seven bays...were main centers". The southernmost limit was Punta Morro Hermoso about 21+1/2 (mi) south of Punta Eugenia, in turn a headland at the southwestern end of Sebastián Vizcaíno Bay, on the west coast of the Baja Peninsula. Otter were also taken from San Benito Island, Cedros Island, and Isla Natividad in the Bay. By.

Sea otter. the early 1900s, Baja's sea otters were extirpated by hunting. In a 1997 survey, small numbers of sea otters, including pups, were reported by local fishermen, but scientists could not confirm these accounts. However, male and female otters have been confirmed by scientists off shores of the Baja Peninsula in a 2014 study, who hypothesize that otter dispersed there beginning in 2005. These sea otters may have dispersed from San Nicolas Island, which is 300 (km) away, as individuals have been recorded traversing distances of over 800 (km). Genetic analysis of most of these animals were consistent with California, i.e.

Sea otter. United States, otter origins, however one otter had a haplotype not previously reported, and could represent a remnant of the original native Mexican otter population.## Ecology.## Diet.High energetic requirements of sea otter metabolism require them to consume at least 20% of their body weight a day. Surface swimming and foraging are major factors in their high energy expenditure due to drag on the surface of the water when swimming and the thermal heat loss from the body during deep dives when foraging. Sea otter muscles are specially adapted to generate heat without physical activity.Sea otters consume over 100 prey species.

Sea otter. also eaten. In studies performed at Amchitka Island in the 1960s, where the sea otter population was at carrying capacity, 50% of food found in sea otter stomachs was fish. The fish species were usually bottom-dwelling and sedentary or sluggish forms, such as "Hemilepidotus hemilepidotus" and family Tetraodontidae. However, south of Alaska on the North American coast, fish are a negligible or extremely minor part of the sea otter's diet. Contrary to popular depictions, sea otters rarely eat starfish, and any kelp that is consumed apparently passes through the sea otter's system undigested.The individuals within a particular area often differ.

Sea otter. and not eat it. On land, young sea otters may face attack from bears and coyotes. In California, great white sharks are their primary predator but there is no evidence that the sharks eat them.Urban runoff transporting cat feces into the ocean brings "Toxoplasma gondii", an obligate parasite of felids, which has killed sea otters. Parasitic infections of "Sarcocystis neurona" are also associated with human activity. According to the U.S. Geological Survey and the CDC, northern sea otters off Washington have been infected with the H1N1 flu virus and "may be a newly identified animal host of influenza viruses".## Relationship.

Sea otter. with humans.## Fur trade.Sea otters have the thickest fur of any mammal, which makes them a common target for many hunters. Archaeological evidence indicates that for thousands of years, indigenous peoples have hunted sea otters for food and fur. Large-scale hunting, part of the Maritime Fur Trade, which would eventually kill approximately one million sea otters, began in the 18th century when hunters and traders began to arrive from all over the world to meet foreign demand for otter pelts, which were one of the world's most valuable types of fur.In the early 18th century, Russians began to hunt sea.

Sea otter. otters in the Kuril Islands and sold them to the Chinese at Kyakhta. Russia was also exploring the far northern Pacific at this time, and sent Vitus Bering to map the Arctic coast and find routes from Siberia to North America. In 1741, on his second North Pacific voyage, Bering was shipwrecked off Bering Island in the Commander Islands, where he and many of his crew died. The surviving crew members, which included naturalist Georg Steller, discovered sea otters on the beaches of the island and spent the winter hunting sea otters and gambling with otter pelts. They returned to.

Sea otter. Siberia, having killed nearly 1,000 sea otters, and were able to command high prices for the pelts. Thus began what is sometimes called the "Great Hunt", which would continue for another hundred years. The Russians found the sea otter far more valuable than the sable skins that had driven and paid for most of their expansion across Siberia. If the sea otter pelts brought back by Bering's survivors had been sold at Kyakhta prices they would have paid for one tenth the cost of Bering's expedition.Russian fur-hunting expeditions soon depleted the sea otter populations in the Commander Islands, and by.

Sea otter. 1745, they began to move on to the Aleutian Islands. The Russians initially traded with the Aleuts inhabitants of these islands for otter pelts, but later enslaved the Aleuts, taking women and children hostage and torturing and killing Aleut men to force them to hunt. Many Aleuts were either murdered by the Russians or died from diseases the hunters had introduced. The Aleut population was reduced, by the Russians' own estimate, from 20,000 to 2,000. By the 1760s, the Russians had reached Alaska. In 1799, Tsar Paul I consolidated the rival fur-hunting companies into the Russian-American Company, granting it an.

Sea otter. imperial charter and protection, and a monopoly over trade rights and territorial acquisition.Under Aleksander I, the administration of the merchant-controlled company was transferred to the Imperial Navy, largely due to the alarming reports by naval officers of native abuse; in 1818, the indigenous peoples of Alaska were granted civil rights equivalent to a townsman status in the Russian Empire.Other nations joined in the hunt in the south. Along the coasts of what is now Mexico and California, Spanish explorers bought sea otter pelts from Native Americans and sold them in Asia. In 1778, British explorer Captain James Cook reached Vancouver.

Sea otter. Island and bought sea otter furs from the First Nations people. When Cook's ship later stopped at a Chinese port, the pelts rapidly sold at high prices, and were soon known as "soft gold". As word spread, people from all over Europe and North America began to arrive in the Pacific Northwest to trade for sea otter furs.Russian hunting expanded to the south, initiated by American ship captains, who subcontracted Russian supervisors and Aleut hunters in what are now Washington, Oregon, and California. Between 1803 and 1846, 72 American ships were involved in the otter hunt in California, harvesting an.

Sea otter. estimated 40,000 skins and tails, compared to only 13 ships of the Russian-American Company, which reported 5,696 otter skins taken between 1806 and 1846. In 1812, the Russians founded an agricultural settlement at what is now Fort Ross in northern California, as their southern headquarters.Eventually, sea otter populations became so depleted, commercial hunting was no longer viable. It had stopped in the Aleutian Islands, by 1808, as a conservation measure imposed by the Russian-American Company. Further restrictions were ordered by the company in 1834. When Russia sold Alaska to the United States in 1867, the Alaska population had recovered to.

Sea otter. over 100,000, but Americans resumed hunting and quickly extirpated the sea otter again. Prices rose as the species became rare. During the 1880s, a pelt brought $105 to $165 in the London market, but by 1903, a pelt could be worth as much as $1,125. In 1911, Russia, Japan, Great Britain (for Canada) and the United States signed the Treaty for the Preservation and Protection of Fur Seals, imposing a moratorium on the harvesting of sea otters. So few remained, perhaps only 1,000–2,000 individuals in the wild, that many believed the species would become extinct.## Recovery and conservation.During the 20th.

Sea otter. Soviet Union in 1991; however, it has declined significantly with stricter law enforcement and better economic conditions.The most significant threat to sea otters is oil spills, to which they are particularly vulnerable, since they rely on their fur to keep warm. When their fur is soaked with oil, it loses its ability to retain air, and the animals can quickly die from hypothermia. The liver, kidneys, and lungs of sea otters also become damaged after they inhale oil or ingest it when grooming. The Exxon Valdez oil spill of 24 March 1989 killed thousands of sea otters in Prince William.

Sea otter. an oil spill wiping out a population. However, because of the species' reputation for depleting shellfish resources, advocates for commercial, recreational, and subsistence shellfish harvesting have often opposed allowing the sea otter's range to increase, and there have even been instances of fishermen and others illegally killing them.In the Aleutian Islands, a massive and unexpected disappearance of sea otters has occurred in recent decades. In the 1980s, the area was home to an estimated 55,000 to 100,000 sea otters, but the population fell to around 6,000 animals by 2000. The most widely accepted, but still controversial, hypothesis is that killer.

Sea otter. whales have been eating the otters. The pattern of disappearances is consistent with a rise in predation, but there has been no direct evidence of orcas preying on sea otters to any significant extent.Another area of concern is California, where recovery began to fluctuate or decline in the late 1990s. Unusually high mortality rates amongst adult and subadult otters, particularly females, have been reported. In 2017 the US Geological Survey found a 3% drop in the sea otter population of the California coast. This number still keeps them on track for removal from the endangered species list, although just barely.

Sea otter. States, Russia and Canada. In marine protected areas, polluting activities such as dumping of waste and oil drilling are typically prohibited. An estimated 1,200 sea otters live within the Monterey Bay National Marine Sanctuary, and more than 500 live within the Olympic Coast National Marine Sanctuary.## Economic impact.Some of the sea otter's preferred prey species, particularly abalone, clams, and crabs, are also food sources for humans. In some areas, massive declines in shellfish harvests have been blamed on the sea otter, and intense public debate has taken place over how to manage the competition between sea otters and humans for.

Sea otter. greatly depleted, no longer rely as intimately on sea mammals for survival.Since the mid-1970s, the beauty and charisma of the species have gained wide appreciation, and the sea otter has become an icon of environmental conservation. The round, expressive face and soft, furry body of the sea otter are depicted in a wide variety of souvenirs, postcards, clothing, and stuffed toys.## Aquariums and zoos.Sea otters can do well in captivity, and are featured in over 40 public aquariums and zoos. The Seattle Aquarium became the first institution to raise sea otters from conception to adulthood with the birth of Tichuk.

Sea otter. in 1979, followed by three more pups in the early 1980s. In 2007, a YouTube video of two sea otters holding paws drew 1.5 million viewers in two weeks, and had over 22 million views . Filmed five years previously at the Vancouver Aquarium, it was YouTube's most popular animal video at the time, although it has since been surpassed. The lighter-colored otter in the video is Nyac, a survivor of the 1989 "Exxon Valdez" oil spill. Nyac died in September 2008, at the age of 20. Milo, the darker one, died of lymphoma in January 2012.

Shaft sinking. Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means.Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve.

Shaft sinking. of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa.The modern shaft sinking industry is gradually shifting further towards greater mechanisation, recent innovations in the form of full-face shaft boring (akin to a vertical tunnel boring machine) have shown promise but the use of this method is, as of 2019, not widespread.## Mine shafts.Mine shafts are vertical or near-vertical tunnels, which are "sunk" as a means of accessing an underground ore body, during of the development of an underground mine.The shape (in plan view), dimensions and depth of mine shafts vary greatly.

Shaft sinking. in response to the specific needs of the mine they are part of and the geology they are sunk through. For example, in North and South America, smaller shafts are designed to be rectangular in plan view with timber supports. Larger shafts are round in plan and are concrete lined.Mine shafts may be used for a variety of purposes, including as a means of escape in the event of an emergency underground and allowing for the movement of: People Materials Mine services (such as compressed air, water, backfill, power, communications and fuel) Ventilation air Broken rock (in the form of.

Shaft sinking. payable ore, or non payable waste) Or any combination of the aboveWhen the top of the excavation is the ground surface, it is referred to as a "shaft"; when the top of the excavation is underground, it is called a "winze" or a "sub-shaft". Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called "raises".A shaft may be either vertical or inclined (between 80 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of.

Shaft sinking. the proposed shaft, and ground conditions allow, then raise boring may be used to excavate the shaft from the bottom up; such shafts are called "borehole shafts".Following the Hartley Colliery disaster where the single shaft at the mine became blocked, the United Kingdom made single shaft mines illegal in 1862, establishing the practice that all underground mines must have a "a second means of egress". Many other global mining jurisdictions have adopted this rule and shafts are therefore often found in pairs (although there are multiple alternative methods of providing a second means of egress).The current the deepest single lift.

Shaft sinking. (i.e. continuous) mine shaft in the world is the 2991m deep, main shaft at South Deep Mine in South Africa, owned by Gold Fields Limited, which, along with its twin ventilation shafts, took ten years to sink and equip.## Parts of a mine shaft.The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist (or winder) used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground).

Shaft sinking. The headframe will also typically contain bins for storing ore being transferred to the processing facility.At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for workers, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out.

Shaft sinking. of the mine.Beneath the collar the part of the shaft which continues into the ground is called the "shaft barrel".At locations where the shaft barrel meets horizontal workings there is a "shaft station" (or inset) which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest shaft station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a "loading pocket" is excavated on one side of the shaft at this.

Shaft sinking. location to allow transfer facilities to be built.Beneath the lowest shaft station the shaft continues on for some distance, this area is referred to as the "shaft bottom". A tunnel called a "ramp" typically connects the bottom of the shaft with the rest of the mine, this ramp often contains the mine's water handling facility, called the "sump", as water will naturally flow to the lowest point in the mine.## Shaft lining.Many (although not all) shafts are lined following excavation and the installation of temporary ground support.The shaft lining performs several functions; it is first and foremost a safety feature.

Shaft sinking. preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into, and lastly a smooth surface to minimise resistance to airflow for ventilation.Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind "shaft forms" in.

Shaft sinking. lifts of 6 m as the shaft advances (gets deeper).Shotcrete, fibrecrete, brick, cast iron tubing, and precast concrete segments have all been used at one time or another. Additionally, the use of materials like bitumen and even squash balls have been required by specific circumstances. In extreme cases, particularly when sinking through halite, composite liners consisting of two or more materials may be required.The shaft liner does not reach right to the bottom of the shaft during sinking, but lags behind by a fixed distance. This distance is determined by the methodology of excavation and the design thickness of the.

Shaft sinking. permanent liner. To ensure the safety of persons working on the shaft bottom temporary ground support is installed, usually consisting of welded mesh and rock bolts. The installation of the temporary ground support (called "bolting") is among the most physically challenging parts of the shaft sinking cycle as bolts must be installed using pneumatic powered rock drills.For this reason, and to minimise the number of persons on the shaft bottom a number of projects have successfully switched to shotcrete for this temporary lining. Research and development in this area is focusing on the robotic application of shotcrete and the commercialisation.

Shaft sinking. of thin sprayed polymer liners.## Shaft compartments.Where the shaft is to be used for hoisting it is frequently split into multiple compartments by "shaft sets", these may be made of either timber or steel. Vertical members in a shaft set are called "guides", horizontal members are called "buntons". For steel shaft guides, the main two options are hollow structural sections and top hat sections. Top hat sections offer a number of advantages over hollow structural sections including simpler installation, improved corrosion resistance and increased stiffness. Mine conveyances run on the guides in a similar way to how a steel roller.

Shaft sinking. coaster runs on its rails, both having wheels which keep them securely in place.Some shafts do not use guide beams but instead utilize steel wire rope (called "guide rope") kept in tension by massive weights at shaft bottom called "cheese weights" (because of their resemblance to a truckle or wheel of cheese) as these are easier to maintain and replace.The largest compartment is typically used for the "mine cage", a conveyance used for moving workers and supplies below the surface, which is suspended from the hoist on steel wire rope. It functions in a similar manner to an elevator. Cages.

Shaft sinking. may be single-, double-, or rarely triple-deck, always having multiple redundant safety systems in case of unexpected failure.The second compartment is used for one or more skips, used to hoist ore to the surface. Smaller mining operations use a skip mounted underneath the cage, rather than a separate device, while some large mines have separate shafts for the cage and skips. The third compartment is used for an emergency exit; it may house an auxiliary cage or a system of ladders. An additional compartment houses mine services such as high voltage cables and pipes for transfer of water, compressed air.

Shaft sinking. or diesel fuel.A second reason to divide the shaft is for ventilation. One or more of the compartments discussed above may be used for air intake, while others may be used for exhaust. Where this is the case a steel or concrete wall called a "brattice" is installed between the two compartments to separate the air flow. At many mines there are one or more complete additional separate "auxiliary shafts" with separate head gear and cages.## Shaft construction.The lowest point in a sinking shaft is known as "shaft bottom", shaft projects differ from some other forms of mine development in.

Shaft sinking. that all activities that take place on shaft bottom become part of the critical path for the project schedule. The infrastructure required to sink a shaft is referred to a "the sinking set-up".It is typical for progress (the "sinking rate") in the sinking phase (that is excavation, ground support and lining) of a shaft project to follow a learning curve as the project team repeat the same series of activities over and over in what is called "the sinking cycle", eventually approaching the theoretical maximum rate for that sinking set up over time. The use of experienced shaft sinkers is.

Shaft sinking. necessary to reduce the length of this learning curve and thus the duration of the project as much as possible.Key to a successful shaft sinking project are: Getting the various components of the sinking set-up correct and installed at the right time. Having experienced people involved from as early in the project as possible Using the available time on shaft bottom as efficiently as possible.Although significant emphasis is placed on the rate of progress of a project sinking cycle by shaft sinkers, sinking is only one of a number of phases in the conventional construction of a new shaft, as.

Shaft sinking. follows; "Box Cut Excavation". A box cut is a large square or rectangular excavation typically completed using earthmoving equipment down to bedrock, inside which the shaft collar will be constructed. Having the loads imposed by the collar, headframe and hoisting plant transferred into solid rock is necessary to prevent unplanned subsidence. Where the depth of bedrock is to great to for a box cut to economically viable, or the bedrock is not strong enough, civil engineering techniques such as diaphragm walls or concrete piles may be used to create a deep foundation instead. "Pre-Sink". The pre-sink is the excavation and.

Shaft sinking. support of the first 60 – 100 meters of the shaft barrel, often completed smaller equipment such as handheld, pneumatic drilling equipment to drill holes for basting and ground support and mini-excavators for mucking. During the pre-sink hoisting of muck and equipment is usually performed by a mobile crane on surface. It is necessary to sink this part of the shaft first so that the Galloway, a multi-level working platform may be installed with enough vertical distance to shaft bottom that it will not be damaged by fly rock during blasting. "Collar Construction". From the bottom of the box-cut, the.

Shaft sinking. shaft collar is constructed bottom up in a planned series of concrete pours. "Galloway (Sinking Stage) Construction & Installation." The Galloway (also known as a Sinking Stage or Scaffold) is a multi-level working platform, suspended in the shaft from winches located on surface. The Galloway allows sinkers to efficiently work on differing levels as required by the various tasks of the sinking cycle. It is typical for the Galloway to be constructed off to one side of the shaft and lowered into the pre-sink with a crane in as complete a state as possible. Once in place the Galloway is.

Shaft sinking. "chaired" (suspended from the shaft collar) while the headframe is built above, often protected by a bulkhead. "Headframe & Hoist House Construction." With the collar constructed and the Galloway installed the headframe and hoist (or winder) houses may be constructed and the hoist and winch ropes installed. Headframes may be either steel or concrete and their design will determine how they are constructed. The Galloway is moved in the shaft by means of winches, which move slowly and are rated for significant loads, while the sinking buckets (or kibbles) are moved in the shaft by the sinking hoist, which moves.

Shaft sinking. quickly and is rates for less load that the winches. To protect the hoist(s) and winches and the sensitive electronics which are used to control their operation they are normally installed inside of a build called a hoist (or winder) house. "Commissioning Sinking Set Up." The Sinking set-up must then be commissioned to ensure that all parts are operating as planned. "Full Sink". The activities of the sinking cycle (excavation, installation of temporary ground support, placement of the shaft lining and extending shaft services) all take place in this phase of construction. In a shaft where there are to be.

Shaft sinking. multiple working levels, shaft stations and station stubs (short lengths of horizontal tunnel leading away from the station) will be developed by the sinkers on the way down. As the equipment to excavate these stations must be small enough to fit through the openings in the Galloway, the rate of advance in developing the station stubs is typically low, compared to what can be achieved with full size mining equipment so station stubs are typically kept as short as possible. "Shaft Equipping & Headframe Changeover." Once the shaft reaches the final design depth, the shaft is stripped of any temporary.

Shaft sinking. services, the Galloway cut up or modified to suit the installation of the permanent shaft set-up, the shaft sets (if required) installed and the headframe / winders modified to allow for permanent hoisting. Any permanent conveyances will be installed at this stage. "Commissioning Permanent Set Up." The Permanent set-up must then be commissioned to ensure that all parts are operating as planned before being handed over to the new owner.As with the depth and design of shafts significant variations do exist in this sequence depending on local conditions, for example in that hard Canadian Shield rocks which dominate shaft sinking.

Shaft sinking. in Canada a deep and complex shaft collar is unnecessary as the bedrock is both strong and close to surface. This reduces the amount of time typically required to establish the shaft collar.Traditionally sinking contractors would build a temporary headframe for the sinking set up, which would then be dismantled to make way for a permanent headframe. With the growth in complexity and duration of shaft sinking projects over time it has become more common to incorporate more of the permanent shaft set-up into the sinking phase. This results in a reduced overall project duration, as for example, if the.

Shaft sinking. service piping used to sink the shaft does not need to be stripped out to make way for permanent piping.With the advancements made in raise boring technology, raise borers have been used to create a pilot hole for shaft sinking, where access exists at the bottom of the new shaft, in this case the sinking phase is dedicated to enlarging this pilot hole to full diameter (a process usually called "slashing"). This methodology can be considerably faster than full face sinking as muck (waste rock) from sinking falls down the pilot hole and is handled using existing mine infrastructure off.

Durdle Door. Durdle Door (sometimes written Durdle Dor) is a natural limestone arch on the Jurassic Coast near Lulworth in Dorset, England. It is privately owned by the Weld Family who own the Lulworth Estate, but it is also open to the public.## Geology.The form of the coastline around Durdle Door is controlled by its geology—both by the contrasting hardnesses of the rocks, and by the local patterns of faults and folds. The arch has formed on a concordant coastline where bands of rock run parallel to the shoreline. The rock strata are almost vertical, and the bands of rock are quite.

Tetrahedron. of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid".Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such nets.For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere (the insphere) tangent to the tetrahedron's faces.## Regular tetrahedron.A regular tetrahedron is a tetrahedron in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which have been known.

Tetrahedron. edge of the base. This follows from the fact that the medians of a triangle intersect at its centroid, and this point divides each of them in two segments, one of which is twice as long as the other (see ).For a regular tetrahedron with side length "a", radius "R" of its circumscribing sphere, and distances "di" from an arbitrary point in 3-space to its four vertices, we haveformula_7## Isometries of the regular tetrahedron.The vertices of a cube can be grouped into two groups of four, each forming a regular tetrahedron (see above, and also , showing one of the.

Other names for the same shape include bisphenoid, isosceles tetrahedron and equifacial tetrahedron.## Orthoschemes.A 3-orthoscheme is a tetrahedron where all four faces are right triangles. An orthoscheme is an irregular simplex that is the convex hull of a tree in which all edges are mutually perpendicular. In a 3-dimensional orthoscheme, the tree consists of three perpendicular edges connecting all four vertices in a linear path that makes two right-angled turns. The 3-orthoscheme is a tetrahedron having two.

Tetrahedron. its characteristic tetrahedron by its planes of symmetry.If the tetrahedron has edge length 2, its characteristic tetrahedron's six edges have lengths , , (the exterior right triangle face, the "characteristic triangle" of the tetrahedron), plus , , (edges that are the "characteristic radii" of the tetrahedron). The 3-edge path along orthogonal edges of the orthoscheme is , , , first from a tetrahedron vertex to an tetrahedron edge center, then turning 90° to an tetrahedron face center, then turning 90° to the tetrahedron center. The orthoscheme has four dissimilar right triangle faces. The exterior face is a 30-60-90 triangle which.

Tetrahedron. is one-sixth of a tetrahedron face. The three faces interior to the tetrahedron are: a right triangle with edges , , , a right triangle with edges , , , and a right triangle with edges , , .## Space-filling tetrahedra.A space-filling tetrahedron packs with directly congruent or enantiomorphous (mirror image) copies of itself to tile space. The cube can be dissected into six 3-orthoschemes, three left-handed and three right-handed (one of each at each cube face), and cubes can fill space, so the characteristic 3-orthoscheme of the cube is a space-filling tetrahedron in this sense. A disphenoid can be.

Then another volume formula is given byformula_25## Properties analogous to those of a triangle.The tetrahedron has many properties analogous to those of a triangle, including an insphere, circumsphere, medial tetrahedron, and exspheres. It has respective centers such as incenter, circumcenter, excenters, Spieker center and points such as a centroid. However, there is generally no orthocenter in the sense of intersecting altitudes.Gaspard Monge found a center that exists in every tetrahedron, now known as the Monge point: the point where the six midplanes of a tetrahedron intersect. A midplane is defined as a plane that is orthogonal to.

Tetrahedron. 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 between its Monge point and circumcenter. These points define the "Euler line" of the tetrahedron that is analogous to the Euler line of a triangle.The nine-point circle of the general triangle has an.

Tetrahedron. face.The radius of the twelve-point sphere is one third of the circumradius of the reference tetrahedron.There is a relation among the angles made by the faces of a general tetrahedron given byformula_26where "α" is the angle between the faces "i" and "j".The geometric median of the vertex position coordinates of a tetrahedron and its isogonic center are associated, under circumstances analogous to those observed for a triangle. Lorenz Lindelöf found that, corresponding to any given tetrahedron is a point now known as an isogonic center, "O", at which the solid angles subtended by the faces are equal, having a common.

What condition on 12 angles is necessary and sufficient for.

Tetrahedron. them to be the 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.## Law of.
