title: "Nephrops norvegicus" content: Nephrops norvegicus Nephrops norvegicus, known variously as the Norway lobster, Dublin Bay prawn, (compare langostino) or scampi, is a slim, orange-pink lobster which grows up to long, and is "the most important commercial crustacean in Europe". It is now the only extant species in the genus "Nephrops", after several other species were moved to the closely related genus "Metanephrops". It lives in the north-eastern Atlantic Ocean, and parts of the Mediterranean Sea, but is absent from the Baltic Sea and Black Sea. Adults emerge from their burrows at night to feed on worms and fish. "Nephrops norvegicus" has the typical

title: "Nephrops norvegicus" content: body shape of a lobster, albeit narrower than the large genus "Homarus". It is pale orange in colour, and grows to a typical length of , or exceptionally long, including the tail and claws. A carapace covers the animal's cephalothorax, while the abdomen is long and segmented, ending in a broad tail fan. The first three pairs of legs bear claws, of which the first are greatly elongated and bear ridges of spines. Of the two pairs of antennae, the second is the longer and thinner. There is a long, spinous rostrum, and the compound eyes are kidney-shaped, providing the

title: "Nephrops norvegicus" content: name of the genus, from the Greek roots ("nephros", "kidney") and "ops" ("eye"). "Nephrops norvegicus" is found in the north-eastern Atlantic Ocean and North Sea as far north as Iceland and northern Norway, and south to Portugal. It is not common in the Mediterranean Sea except in the Adriatic Sea, notably the north Adriatic. It is absent from both the Black Sea and the Baltic Sea. Due to its ecological demands for particular sediments, "N. norvegicus" has a very patchy distribution, and is divided into over 30 populations. These populations are separated by inhospitable terrain, and adults rarely travel distances

title: "Nephrops norvegicus" content: greater than a few hundred metres. "Nephrops norvegicus" adults prefer to inhabit muddy seabed sediments, with more than 40 percent silt and clay. Their burrows are semi-permanent, and vary in structure and size. Typical burrows are deep, with a distance of between the front and back entrances. Norway lobsters spend most of their time either lying in their burrows or by the entrance, only leaving their shelters to forage or mate. "Nephrops norvegicus" is a scavenger and predator that makes short foraging excursions, mainly during periods of subdued light. They feed on active prey, including worms and fish, which they

title: "Nephrops norvegicus" content: capture with their chelipeds and walking legs, and food is conveyed to the mouth using the anterior walking legs, assisted by the maxillipeds. There is evidence that "Nephrops norvegicus" is a major eater of jellyfish. "Nephrops norvegicus" is the host to a number of parasites and symbionts. A number of sessile organisms attach to the exoskeleton of "N. norvegicus", including the barnacle "Balanus crenatus" and the foraminiferan "Cyclogyra", but overall "Nephrops" suffers fewer infestations of such epibionts than other decapod crustaceans do. In December 1995, the commensal "Symbion pandora" was discovered attached to the mouthparts of "Nephrops norvegicus", and was

title: "Nephrops norvegicus" content: found to be the first member of a new phylum, Cycliophora, a finding described by Simon Conway Morris as "the zoological highlight of the decade". "S. pandora" has been found in many populations of "N. norvegicus", both in the north Atlantic and in the Mediterranean Sea. Individuals may be found on most segments of the lobster's mouthparts, but are generally concentrated on the central parts of the larger mouthparts, from the mandible to the third maxilliped. The most significant parasite of "N. norvegicus" is a dinoflagellate of the genus "Hematodinium", which has caused epidemic infection in fished populations of "N.

title: "Nephrops norvegicus" content: norvegicus" since the 1980s. "Hematodinium" is a genus that contains major pathogens of a wide variety of decapod crustaceans, although its internal taxonomy is poorly resolved. The species which attacks "N. norvegicus" causes a syndrome originally described as "post-moult syndrome", in which the carapace turns opaque and becomes highly pigmented, the haemolymph becomes milky white, and the animal appears moribund. Other parasites of "N. norvegicus" include the gregarine protozoan "Porospora nephropis", the trematode "Stichocotyle nephropis" and the polychaete "Histriobdella homari". The typical life span of "N. norvegicus" is 5–10 years, reaching 15 years in exceptional cases. Its reproductive cycle varies

title: "Nephrops norvegicus" content: depending on geographical position: "the periods of hatching and spawning, and the length of the incubation period, vary with latitude and the breeding cycle changes from annual to biennial as one moves from south to north". Incubation of eggs is temperature-dependent, and in colder climates, the duration of the incubation period increases. This means that, by the time hatching occurs, it may be too late for the females to take part in that year's breeding cycle. In warmer climates, the combined effects of recovery from moulting and ovary maturation mean that spawning can become delayed. This, in turn, has the

title: "Nephrops norvegicus" content: effect of the female missing out a year of egg carrying. Adult male "Nephrops norvegicus" moult once or twice a year (usually in late winter or spring) and adult females moult up to once a year (in late winter or spring, after hatching of the eggs). In annual breeding cycles, mating takes place in the spring or winter, when the females are in the soft, post-moult state. The ovaries mature throughout the spring and summer months, and egg-laying takes place in late summer or early autumn. After spawning, the berried (egg-carrying) females return to their burrows and remain there until

title: "Nephrops norvegicus" content: the end of the incubation period. Hatching takes place in late winter or early spring. Soon after hatching, the females moult and mate again. During the planktonic larval stage (typically 1 to 2 months in duration) the nephrops larvae exhibit a diel vertical migration behaviour as they are dispersed by the local currents. This complex biophysical interaction determines the fate of the larvae; the overlap between advective pathway destination and spatial distributions of suitable benthic habitats must be favourable in order for the larvae to settle and reach maturity. The muscular tail of "Nephrops norvegicus" is frequently eaten, and its

title: "Nephrops norvegicus" content: meat is known as "scampi". The "N. norvegicus" is eaten only on special occasions in Spain and Portugal, where it is less expensive than the common lobster, "Homarus gammarus". "N. norvegicus" is an important species for fisheries, being caught mostly by trawling. Around 60,000 tonnes are caught annually, half of it in the United Kingdom's waters. Besides the established trawling fleets, a significant number of fleets using lobster creels have developed. The better size and condition of lobsters caught by this method yield prices three to four times higher than animals netted by trawling. Creel fishing was found to have

title: "Nephrops norvegicus" content: a reduced impact on the seafloor, require lower fuel consumption, and allow fishermen with smaller boats to participate in this high-value fishery. It has therefore been described as a reasonable alternative to demersal towed gears, and the allocation of additional fishing rights for this type of take has been suggested. The North East Atlantic individual biological stocks of Nephrops are identified as functional units. A number of functional units make up the sea areas over which a total allowable catch (TAC) is set annually by the EU Council of Ministers. For example, the TAC set for North Sea Nephrops is

title: "Nephrops norvegicus" content: based on the aggregate total tonnage of removals recommended by science for nine separate functional unit areas. This method has attracted criticism because it can promote the over-exploitation of a specific functional unit even though the overall TAC is under-fished. In 2016, the UK implemented a package of emergency technical measures with the cooperation of the fishing industry aimed at reducing fishing activity to induce recovery of the Nephrops stock in the Farn(e) Deeps off North East England which was close to collapse. A stock assessment completed in 2018 by the International Council for the Exploration of the Sea (ICES)

title: "Nephrops norvegicus" content: shows that fishing pressure has been cut and this stock is now below FMSY and that stock size is above MSY Btrigger meaning that the Farne Deeps nephrops stock is being fished at a sustainable level. However, ICES also warn that any substantial transfer of the current surplus fishing opportunities from other functional units to the Farne Deeps would rapidly lead to overexploitation. This suggests that controls on fishing effort should continue at least until the biomass reaches a size that is sustainable when measured against the level of fishing activity by all fishermen wanting to target the stock. Discards

title: "Nephrops norvegicus" content: from "Nephrops" fishery may account for up to 37% of the energy requirements of certain marine scavengers, such as the hagfish "Myxine glutinosa". Boats involved in "Nephrops" fishery also catch a number of fish species such as plaice and sole, and it is thought that without that revenue, "Nephrops" fishery would be economically unviable. "Nephrops norvegicus" was one of the species included by Carl Linnaeus in his 1758 10th edition of ', the starting point for zoological nomenclature. In that work, it was listed as ', with a type locality of "" ("in the Norwegian sea"). In choosing a lectotype,

title: "Nephrops norvegicus" content: Lipke Holthuis restricted the type locality to the Kattegat at the Kullen Peninsula in southern Sweden (). Two synonyms of the species have been published – ""Astacus rugosus"", described by the eccentric zoologist Constantine Samuel Rafinesque in 1814 from material collected in the Mediterranean Sea, and ""Nephropsis cornubiensis"", described by Charles Spence Bate and Joshua Brooking Rowe in 1880. As new genera were erected, the species was moved, reaching its current position in 1814, when William Elford Leach erected the genus "Nephrops" to hold this species alone. Seven fossil species have since been described in the genus. Populations in the

A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries (137.5 million/year or 243.8 billion passenger km in 1990), remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries. With a cruising speed of the Tu-154 is one of

Capable of operating from unpaved and gravel airfields with only basic facilities, it was widely used in the extreme Arctic conditions of Russia's northern/eastern regions where other airliners were unable to operate. Originally designed for a 45,000 hour service life (18,000 cycles) but capable of 80,000 hours with upgrades, it was expected to continue in service until 2016, although noise regulations have restricted flights to western Europe and other regions. In January 2010 Russian flag carrier Aeroflot announced the retirement of its Tu-154 fleet after 40 years, with

title: "Tupolev Tu-154" content: the last scheduled flight being Aeroflot Flight 736 from Ekaterinburg to Moscow on 31 December 2009. Since 1968 there have been 39 fatal incidents involving the Tu-154, most of which were caused either by factors unrelated to the aircraft, incorrect maintenance, or by its extensive use in demanding conditions. The Tu-154 was developed to meet Aeroflot's requirement to replace the jet-powered Tu-104 and the Antonov An-10 and Ilyushin Il-18 turboprops. The requirements called for either a payload capacity of with a range of while cruising at , or a payload of with a range of while cruising at . A

Conceptually similar to the British Hawker Siddeley Trident, which first flew in 1962, and the American Boeing 727, which first flew in 1963, the medium-range Tu-154 was marketed by Tupolev at the same time as Ilyushin was marketing the long-range Ilyushin Il-62. The Soviet Ministry of Aircraft Industry chose the Tu-154 as it incorporated the latest in Soviet aircraft design and best met Aeroflot's anticipated requirements for the 1970s and 1980s. The first project chief was Sergey Yeger; in 1964, Dmitryi S. Markov assumed that position. In

title: "Tupolev Tu-154" content: 1975, the project lead role was turned over to Aleksandr S. Shengardt. The Tu-154 first flew on 4 October 1968. The first deliveries to Aeroflot were in 1970 with freight (mail) services beginning in May 1971 and passenger services in February 1972. There was still limited production of the 154M model as of January 2009 despite previous announcements of the end of production in 2006. 1025 Tu-154s have been built, 214 of which were still in service as of 14 December 2009.

A twin-engine replacement for the single-engine DHC-3 Otter retaining DHC's renowned STOL qualities, its design features included double-slotted trailing-edge flaps and ailerons that work in unison with the flaps to boost STOL performance. The availability of the Pratt & Whitney Canada PT6A-20 turboprop in the early 1960s made the concept of a twin more feasible. To bush operators, the improved reliability of turboprop power and the improved performance of a twin-engine configuration made it an immediately popular

The first six aircraft produced were designated Series 1, indicating that they were prototype aircraft. The initial production run consisted of Series 100 aircraft, serial numbers seven to 115 inclusive. In 1968, Series 200 production began with serial number 116. Changes made at the beginning of Series 200 production included improving the STOL performance, adding a longer nose that was equipped with a larger baggage compartment (except for aircraft fitted with floats), and fitting a larger door to the rear baggage compartment. All Series 1, 100, and 200 aircraft

In 1969, the Series 300 was introduced, beginning with serial number 231. Both aircraft performance and payload were improved by fitting more powerful PT6A-27 engines. This was a engine that was flat-rated to for use in the Series 300 Twin Otter. The Series 300 proved to be the most successful variant by far, with 614 Series 300 aircraft and their subvariants (Series 310 for United Kingdom operators, Series 320 for Australian operators, etc.) sold before production in Toronto by de Havilland Canada ended in 1988. In 1976, a

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

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

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 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

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. Following the placement of the final major

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

With valid registration, these plates remain visible on the road today. 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.

title: "Memorial to the Murdered Jews of Europe" content: Memorial to the Murdered Jews of Europe The Memorial to the Murdered Jews of Europe (), also known as the Holocaust Memorial (German: "Holocaust-Mahnmal"), is a memorial in Berlin to the Jewish victims of the Holocaust, designed by architect Peter Eisenman and engineer Buro Happold. It consists of a site covered with 2,711 concrete slabs or "stelae", arranged in a grid pattern on a sloping field. The stelae are long, wide and vary in height from . They are organized in rows, 54 of them going north–south, and 87 heading east–west at right angles but set slightly askew. An attached

title: "Memorial to the Murdered Jews of Europe" content: underground "Place of Information" () holds the names of approximately 3 million Jewish Holocaust victims, obtained from the Israeli museum Yad Vashem. Building began on April 1, 2003, and was finished on December 15, 2004. It was inaugurated on May 10, 2005, sixty years after the end of World War II, and opened to the public two days later. It is located one block south of the Brandenburg Gate, in the Mitte neighborhood. The cost of construction was approximately €25 million. The memorial is located on Cora-Berliner-Straße 1, 10117 in Berlin, a city with one of the largest Jewish populations

title: "Memorial to the Murdered Jews of Europe" content: the grey flat stones and the blue sky as a recognition of the "dismal times" of the Holocaust. As one slopes downwards into the memorial entrance, the grey pillars begin to grow taller until they completely consume the visitor. Eventually the grey pillars become smaller again as visitors ascend towards the exit. Some have interpreted this as the rise and fall of the Third Reich or the Regime's gradual momentum of power that allowed them to perpetrate such atrocities on the Jewish community. The space in between the concrete pillars offers a brief encounter with the sunlight. As visitors wander

title: "Memorial to the Murdered Jews of Europe" content: from society and eventually they were removed from existence. The more a visitor descends into the memorial, he or she is without any visible contact of the outside world. He or she is completely ostracized and hidden from the world. It is common for groups of visitors to lose each other as they wander deeper into the memorial. This often reminds one of the separation and loss of family among the Jewish community during the Holocaust. Some have interpreted the shape and color of the grey slabs to represent the loss of identity during the Nazi regime. As one moves

title: "Memorial to the Murdered Jews of Europe" content: lack of unified shape within the group of blocks has also been understood as a symbolic representation of the "task of remembering". Some of the blocks appear to be unfinished. Many see this unfinished appearance as asserting that the task of remembering the Holocaust is never over. Benjamin has said "The monument works to maintain the incomplete". As the effects of the Holocaust are impossible to fully represent, the memorial's structures have remained unfinished. The missing parts of the structure illustrate the missing members of the Jewish community that will never return. The destruction of the Holocaust has resulted in

title: "Memorial to the Murdered Jews of Europe" content: a missing epoch of Jewish heritage. The memorial's structures also deny any sense of collectivity. Some have interpreted this to reflect the lack of collective guilt amongst the German population. Others have interpreted the spatial positioning of the blocks to represent an individual guilt for the Holocaust. Many Germans have viewed the memorial as targeting German society and claim the memorial is presented as "an expression of our – non-Jewish Germans' – responsibility for the past". The site is also enclosed by borders of trees and Berlin's center city. The enclosure from these borders has often evoked feelings of entrapment.

title: "Memorial to the Murdered Jews of Europe" content: This can be understood as a symbolic representation of the closure of European and American borders following the Evian Conference that forced Jews to stay in Germany. Three years after the official opening of the memorial, half of the blocks made from compacting concrete started to crack. While some interpret this defect as an intentional symbolization of the immortality and durability of the Jewish community, the Memorials' Foundation deny this. Many analyze the lack of individual names on the monument as an illustration of the unimaginable number of murdered Jews in the Holocaust. In this way, the memorial illustrates that

title: "Memorial to the Murdered Jews of Europe" content: the number of Jewish individuals lost in the Holocaust was so colossal that is impossible to physically visualize. Several have noted that the number of stelae is identical to the number of pages in the Babylonian Talmud. The information center, which is located at the site's eastern edge, begins with a timeline that lays out the history of the Final Solution, from when the National Socialists took power in 1933 through the murder of 500,000 Soviet Jews in 1941. The rest of the exhibition is divided into four rooms dedicated to personal aspects of the tragedy, e.g. the individual families

title: "Memorial to the Murdered Jews of Europe" content: or the letters thrown from the trains that transported them to the death camps. The "Room of Families" focuses on the fates of 15 specific Jewish families. In the "Room of Names", names of all known Jewish Holocaust victims obtained from the Yad Vashem memorial in Israel are read out loud. Each chamber contains visual reminders of the stelae above: rectangular benches, horizontal floor markers and vertical illuminations. Critics have questioned the placement of the center. It is discreetly placed on the eastern edge of the monument. Architecturally, the information center's most prominent feature lies in its coffered concrete ceilings.

title: "Memorial to the Murdered Jews of Europe" content: The undulating surfaces mirror the pattern of the pillars and pathways overhead, causing the visitor to feel like they have entered a collection of graves. "Aesthetically, the Information Center runs against every intention of the open memorial. The aboveground pavilion of the subterranean documentation area mars the steady measure of the order of rectangles. Admittedly, all objections against this pedagogical extra fall silent when one has descended the stairs to the Information Center and entered the first four rooms". The visitors center contains and displays some of the most important moments and memories of the Holocaust, through carefully chosen examples

The entrances cut through the network of paths defined by the stelae, and the exhibit area gives the memorial that which by its very conception it should not have: a defined attraction. "The exhibitions are literal, a sharp contrast to the amorphous stelae that the memorial is composed of. "It is as if they (exhibits) were directed at people who cannot find the capacity to believe that the Holocaust occurred". The debates over whether to have such a memorial and what form it should take extend back to the late 1980s, when a small

With growing support, the Bundestag passed a resolution in favour of the project. On 25 June 1999, the German Federal Parliament decided to build the memorial designed by Peter Eisenman.

It would be tilted, rising up to eleven meters and walkable on special paths.

In July 2001, the provocative slogan "The Holocaust never happened" appeared in newspaper advertisements and on billboards seeking donations of $2 million for the memorial. Under the slogan and a picture of a serene mountain lake and snow-capped mountain, a smaller type said: "There are still many people who make this claim. In 20 years there could be even more."

The inauguration ceremony, attended by all the senior members of Germany's government, including Chancellor Gerhard Schröder, took place in a large white tent set up on the edge of the memorial field itself, only yards from the place where Hitler's underground bunker was. Holocaust survivor Sabina Wolanski was chosen to speak on behalf of the six million dead. In her speech, she noted that although the Holocaust had taken everything she valued, it had also taught her that hatred and discrimination are doomed to fail.

The medley of Hebrew and Yiddish songs that followed the speeches was sung by Joseph Malovany, cantor of the Fifth Avenue Synagogue in New York, accompanied by the choir of the White Stork Synagogue in Wrocław, Poland, and by the Lower Silesian German-Polish Philharmonic Youth Orchestra. In the first year after it opened in May 2005, the monument attracted over 3.5 million visitors. It is estimated that some 5 million visitors have visited the Information Centre between its opening

title: "Memorial to the Murdered Jews of Europe" content: in May 2005 and December 2015. Over the past 10 years (2006–2015), an average of 460,000 people have visited, or over 1,000 per day. The foundation operating the memorial considered this a success; its head, Uwe Neumärker, called the memorial a "tourist magnet". The monument has been criticized for only commemorating the Jewish victims of the Holocaust, however, other memorials have subsequently opened which commemorate other identifiable groups that were also victims of the Nazis, for example, the Memorial to Homosexuals Persecuted Under Nazism (in 2008) and the Memorial to the Sinti and Roma Victims of National Socialism (in 2012).

title: "Memorial to the Murdered Jews of Europe" content: Many critics argued that the design should include names of victims, as well as the numbers of people killed and the places where the killings occurred. Meanwhile, architecture critic Nicolai Ouroussoff claimed the memorial "is able to convey the scope of the Holocaust's horrors without stooping to sentimentality – showing how abstraction can be the most powerful tool for conveying the complexities of human emotion." Some Germans have argued the memorial is only statuary and does little to honor those murdered during the Nazi Regime. Some claimed the erection of the memorial ignored Germany's responsibility to engage in more active

Several months later, when accepting the Peace Prize of the German Book Trade, German novelist Martin Walser cited the Holocaust Memorial. Walser decried "the exploitation of our disgrace for present purposes." He criticized the "monumentalization", and "ceaseless presentation of our shame." And said: "Auschwitz is not suitable for becoming a routine-of-threat, an always available intimidation or a moral club [Moralkeule] or also just an obligation. What is produced by ritualisation, has the quality of a lip service". Eberhard Diepgen, mayor of Berlin 1991–2001, had publicly opposed the memorial and did not attend

The emerging trend met with mixed responses: while Grindr's CEO Joel Simkhai was "deeply moved" by how app members "take part in the memory of the holocaust", others found using the memorial as a backdrop for hook up profiles to be disrespectful. The monument is often used as a recreational space, inciting anger from those who see the playful use of the space as a desecration of the memorial.

Michal Bodemann, a professor of sociology at the University of Toronto, is critical of what he calls the "permanent" and "brooding" culture of Holocaust commemoration in Germany. He studies postwar German-Jewish relations and told Die Tageszeitung that Germany's focus on the past overlooks the racist tendencies in society today and suggests a hopelessness toward the future. "My impression is that you hide yourself away in history in order to keep the present from cutting too close". Many critics found the "vagueness" of the stelae disturbing. The concrete blocks offer

Critics have raised questions about the memorial's lack of information. "It doesn't say anything about who did the murdering or why—there's nothing along the lines of "by Germany under Hitler's regime," and the vagueness is disturbing". The question of the dedication of the memorial is even more powerful. "In its radical refusal of the inherited iconography of remembrance, Berlin's field of stones also forgoes any statement about its own reason for existence. The installation gives no indication who is to

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

title: Tetrahedron content: In the case 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. A regular tetrahedron is one in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which

title: Tetrahedron content: from "C" to the midpoint of an 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 "d" from an arbitrary point in 3-space to its four vertices, we have The vertices of a cube can be grouped into two groups of four, each forming a regular tetrahedron (see above, and also ,

title: Tetrahedron content: on this plane, both halves become wedges. This property also applies for tetragonal disphenoids when applied to the two special edge pairs. The tetrahedron can also be represented as a spherical tiling, and projected onto the plane via a stereographic projection. This projection is conformal, preserving angles but not areas or lengths. Straight lines on the sphere are projected as circular arcs on the plane. An isosceles tetrahedron, also called a disphenoid, is a tetrahedron where all four faces are congruent triangles. A space-filling tetrahedron packs with congruent copies of itself to tile space, like the disphenoid tetrahedral honeycomb. In

title: Tetrahedron content: the 1st century Heron's formula for the area of a triangle. Denote "a,b,c" be three edges that meet at a point, and "x,y,z" the opposite edges. Let "V" be the volume of the tetrahedron; then where The above formula uses different expressions with the following formula,The above formula uses six lengths of edges, and the following formula uses three lengths of edges and three angles. If "U", "V", "W", "u", "v", "w" are lengths of edges of the tetrahedron (first three form a triangle; "u" opposite to "U" and so on), then where A plane that divides two opposite edges

title: Tetrahedron content: lie on two skew lines, and the distance between the edges is defined as the distance between the two skew lines. Let "d" be the distance between the skew lines formed by opposite edges a and as calculated here. Then another volume formula is given by 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

title: Tetrahedron content: 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 analogue in the circumsphere of a tetrahedron's medial tetrahedron. It is the twelve-point sphere and besides the centroids of the four faces of the reference tetrahedron, it passes through four substitute "Euler points", one third of the way from the Monge point toward each of the four vertices. Finally it passes through the four base points of orthogonal lines dropped from each Euler point to the

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
