Toronto is the provincial capital of Ontario and the most populous city in Canada, with a population of 2,731,571 in 2016. Current to 2016, the Toronto census metropolitan area, of which the majority is within the Greater Toronto Area, held a population of 5,928,040, making it Canada's most populous CMA. Toronto is the anchor of an urban agglomeration, known as the Golden Horseshoe in Southern Ontario, located on the northwestern shore of Lake Ontario. A global city, Toronto is a centre of business, finance and culture, is recognized as one of the most multicultural and cosmopolitan cities in the world. People have travelled through and inhabited the Toronto area, situated on a broad sloping plateau interspersed with rivers, deep ravines, urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and designated it as the capital of Upper Canada. During the War of 1812, the town was the site of the Battle of York and suffered heavy damage by United States troops.
York was incorporated in 1834 as the city of Toronto. It was designated as the capital of the province of Ontario in 1867 during Canadian Confederation; the city proper has since expanded past its original borders through both annexation and amalgamation to its current area of 630.2 km2. The diverse population of Toronto reflects its current and historical role as an important destination for immigrants to Canada. More than 50 percent of residents belong to a visible minority population group, over 200 distinct ethnic origins are represented among its inhabitants. While the majority of Torontonians speak English as their primary language, over 160 languages are spoken in the city. Toronto is a prominent centre for music, motion picture production, television production, is home to the headquarters of Canada's major national broadcast networks and media outlets, its varied cultural institutions, which include numerous museums and galleries and public events, entertainment districts, national historic sites, sports activities, attract over 25 million tourists each year.
Toronto is known for its many skyscrapers and high-rise buildings, in particular the tallest free-standing structure in the Western Hemisphere, the CN Tower. The city is home to the Toronto Stock Exchange, the headquarters of Canada's five largest banks, the headquarters of many large Canadian and multinational corporations, its economy is diversified with strengths in technology, financial services, life sciences, arts, business services, environmental innovation, food services, tourism. When Europeans first arrived at the site of present-day Toronto, the vicinity was inhabited by the Iroquois, who had displaced the Wyandot people, occupants of the region for centuries before c. 1500. The name Toronto is derived from the Iroquoian word tkaronto, meaning "place where trees stand in the water"; this refers to the northern end of what is now Lake Simcoe, where the Huron had planted tree saplings to corral fish. However, the word "Toronto", meaning "plenty" appears in a 1632 French lexicon of the Huron language, an Iroquoian language.
It appears on French maps referring to various locations, including Georgian Bay, Lake Simcoe, several rivers. A portage route from Lake Ontario to Lake Huron running through this point, known as the Toronto Carrying-Place Trail, led to widespread use of the name. In the 1660s, the Iroquois established two villages within what is today Toronto, Ganatsekwyagon on the banks of the Rouge River and Teiaiagon on the banks of the Humber River. By 1701, the Mississauga had displaced the Iroquois, who abandoned the Toronto area at the end of the Beaver Wars, with most returning to their base in present-day New York. French traders abandoned it in 1759 during the Seven Years' War; the British defeated the French and their indigenous allies in the war, the area became part of the British colony of Quebec in 1763. During the American Revolutionary War, an influx of British settlers came here as United Empire Loyalists fled for the British-controlled lands north of Lake Ontario; the Crown granted them land to compensate for their losses in the Thirteen Colonies.
The new province of Upper Canada was being needed a capital. In 1787, the British Lord Dorchester arranged for the Toronto Purchase with the Mississauga of the New Credit First Nation, thereby securing more than a quarter of a million acres of land in the Toronto area. Dorchester intended the location to be named Toronto. In 1793, Governor John Graves Simcoe established the town of York on the Toronto Purchase lands, naming it after Prince Frederick, Duke of York and Albany. Simcoe decided to move the Upper Canada capital from Newark to York, believing that the new site would be less vulnerable to attack by the United States; the York garrison was constructed at the entrance of the town's natural harbour, sheltered by a long sand-bar peninsula. The town's settlement formed at the eastern end of the harbour behind the peninsula, near the present-day intersection of Parliament Street and Front Street. In 1813, as part of the War of 1812, the Battle of York ended in the town's capture and plunder by United States forces.
The surrender of the town was negotiated by John Strachan. American soldiers destroyed much of the garrison and set fire to the parliament buildings during their five-day occupation; because of the sacking of York, British troops retaliated in the war with the Burning of Wa
Shanghai is one of the four municipalities under the direct administration of the central government of the People's Republic of China, the largest city in China by population, the second most populous city proper in the world, with a population of 24.18 million as of 2017. It is a transport hub, with the world's busiest container port. Located in the Yangtze River Delta, it sits on the south edge of the estuary of the Yangtze in the middle portion of the East China coast; the municipality borders the provinces of Jiangsu and Zhejiang to the north and west, is bounded to the east by the East China Sea. As a major administrative and trading city, Shanghai grew in importance in the 19th century due to trade and recognition of its favourable port location and economic potential; the city was one of five treaty ports forced open to foreign trade following the British victory over China in the First Opium War. The subsequent 1842 Treaty of Nanking and 1844 Treaty of Whampoa allowed the establishment of the Shanghai International Settlement and the French Concession.
The city flourished as a centre of commerce between China and other parts of the world, became the primary financial hub of the Asia-Pacific region in the 1930s. During the World War II, the city was the site of the major Battle of Shanghai. After the war, with the Communist Party takeover of the mainland in 1949, trade was limited to other socialist countries, the city's global influence declined. In the 1990s, the economic reforms introduced by Deng Xiaoping resulted in an intense re-development of the city, aiding the return of finance and foreign investment to the city, it has since re-emerged as a hub for international finance. Shanghai has been described as the "showpiece" of the booming economy of mainland China; the two Chinese characters in the city's name are 上 and 海, together meaning "Upon-the-Sea". The earliest occurrence of this name dates from the 11th-century Song dynasty, at which time there was a river confluence and a town with this name in the area. There are disputes as to how the name should be understood, but Chinese historians have concluded that during the Tang dynasty Shanghai was on the sea.
Shanghai is abbreviated 沪 in Chinese, a contraction of 沪渎, a 4th- or 5th-century Jin name for the mouth of Suzhou Creek when it was the main conduit into the ocean. This character appears on all motor vehicle license plates issued in the municipality today. Another alternative name for Shanghai is Shēn or Shēnchéng, from Lord Chunshen, a 3rd-century BC nobleman and prime minister of the state of Chu, whose fief included modern Shanghai. Sports teams and newspapers in Shanghai use Shen in their names, such as Shanghai Shenhua F. C. and Shen Bao. Huating was another early name for Shanghai. In AD 751, during the mid-Tang dynasty, Huating County was established by the Governor of Wu Commandery Zhao Juzhen at modern-day Songjiang, the first county-level administration within modern-day Shanghai. Today, Huating appears as the name of a four-star hotel in the city; the city has various nicknames in English, including "Pearl of the Orient" and "Paris of the East". During the Spring and Autumn period, the Shanghai area belonged to the Kingdom of Wu, conquered by the Kingdom of Yue, which in turn was conquered by the Kingdom of Chu.
During the Warring States period, Shanghai was part of the fief of Lord Chunshen of Chu, one of the Four Lords of the Warring States. He ordered the excavation of the Huangpu River, its former or poetic name, the Chunshen River, gave Shanghai its nickname of "Shēn". Fishermen living in the Shanghai area created a fish tool called the hù, which lent its name to the outlet of Suzhou Creek north of the Old City and became a common nickname and abbreviation for the city. During the Tang and Song dynasties, Qinglong Town in modern Qingpu District was a major trading port. Established in 746, it developed into what contemporary sources called a "giant town of the Southeast", with thirteen temples and seven pagodas; the famous Song scholar and artist Mi Fu served as its mayor. The port had a thriving trade with provinces along the Yangtze River and the Chinese coast, as well as foreign countries such as Japan and Silla. By the end of the Song dynasty, the center of trading had moved downstream of the Wusong River to Shanghai, upgraded in status from a village to a market town in 1074, in 1172 a second sea wall was built to stabilize the ocean coastline, supplementing an earlier dike.
From the Yuan dynasty in 1292 until Shanghai became a municipality in 1927, central Shanghai was administered as a county under Songjiang Prefecture, whose seat was at the present-day Songjiang District. Two important events helped promote Shanghai's development in the Ming dynasty. A city wall was built for the first time in 1554 to protect the town from raids by Japanese pirates, it measured 10 metres high and 5 kilometres in circumference. During the Wanli reign, Shanghai received an important psychological boost from the erection of a City God Temple in 1602; this honour was reserved for prefectural capitals and not given to a mere county seat such as Shang
The CN Tower is a 553.3 m-high concrete communications and observation tower located in Downtown Toronto, Canada. Built on the former Railway Lands, it was completed in 1976, its name "CN" referred to Canadian National, the railway company that built the tower. Following the railway's decision to divest non-core freight railway assets prior to the company's privatization in 1995, it transferred the tower to the Canada Lands Company, a federal Crown corporation responsible for real estate development; the CN Tower held the record for the world's tallest free-standing structure for 32 years until 2007 when it was surpassed by the Burj Khalifa and was the world's tallest tower until 2009 when it was surpassed by the Canton Tower. It is now the ninth tallest free-standing structure in the world and remains the tallest free-standing structure in the Western Hemisphere. In 1995, the CN Tower was declared one of the modern Seven Wonders of the World by the American Society of Civil Engineers, it belongs to the World Federation of Great Towers.
It is a signature icon of Toronto's skyline and attracts more than two million international visitors annually. The original concept of the CN Tower originated in 1968 when the Canadian National Railway wanted to build a large TV and radio communication platform to serve the Toronto area, as well as demonstrate the strength of Canadian industry and CN in particular; these plans evolved over the next few years, the project became official in 1972. The tower would have been part of Metro Centre, a large development south of Front Street on the Railway Lands, a large railway switching yard, being made redundant by newer yards outside the city. Key project team members were NCK Engineering as structural engineer; as Toronto grew during the late 1960s and early 1970s, multiple skyscrapers were constructed in the downtown core, most notably First Canadian Place. The reflective nature of the new buildings compromised the quality of broadcast signals necessitating new, higher antennas that were at least 300 m tall.
At the time, most data communications took place over point-to-point microwave links, whose dish antennae covered the roofs of large buildings. As each new skyscraper was added to the downtown, former line-of-sight links were no longer possible. CN intended to rent "hub" space for microwave links, visible from any building in the Toronto area; the CN Tower can be seen from at least as far away as Kennedy Street in Aurora, Ontario 40 km to the north. It is viewable to the naked eye from 60 km east of Toronto in Oshawa, several points along the Niagara Escarpment west of Toronto in Hamilton, 48 km to the south from Fort Niagara State Park in the U. S. state of New York. The original plan for the tower envisioned a tripod consisting of three independent cylindrical "pillars" linked at various heights by structural bridges. Had it been built, this design would have been shorter, with the metal antenna located where the concrete section between the main level and the SkyPod lies today; as the design effort continued, it evolved into the current design with a single continuous hexagonal core to the SkyPod, with three support legs blended into the hexagon below the main level, forming a large Y-shape structure at the ground level.
The idea for the main level in its current form evolved around this time, but the Space Deck was not part of the plans until some time later. One engineer in particular felt that visitors would feel the higher observation deck would be worth paying extra for, the costs in terms of construction were not prohibitive, it was some time around this point that it was realized that the tower could become the world's tallest structure, plans were changed to incorporate subtle modifications throughout the structure to this end. Construction on the CN Tower began on February 6, 1973, with massive excavations at the tower base for the foundation. By the time the foundation was complete, 56,000 t of earth and shale were removed to a depth of 15 m in the centre, a base incorporating 7,000 m3 of concrete with 450 t of rebar and 36 t of steel cable had been built to a thickness of 6.7 m. This portion of the construction was rapid, with only four months needed between the start and the foundation being ready for construction on top.
To create the main support pillar, workers constructed a hydraulically raised slipform at the base. This was a unprecedented engineering feat on its own, consisting of a large metal platform that raised itself on jacks at about 6 m per day as the concrete below set. Concrete was poured continuously by a team of 1,532 people until February 22, 1974, during which it had become the tallest structure in Canada, surpassing the built Inco Superstack in Sudbury, built using similar methods. In total, the tower contains 40,500 m3 of concrete, all of, mixed on-site in order to ensure batch consistency. Through the pour, the vertical accuracy of the tower was maintained by comparing the slip form's location to massive plumb bobs hanging from it, observed by small telescopes from the ground. Over the height of the tower, it varies from true vertical accuracy by only 29 mm. In August 1974, construction of the main level commenced. Using 45 hydraulic jacks attached to cables strung from a temporary steel crown anchored to the top of the tower, twelve giant steel
Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the countries that are geographically south of China and Japan, east of India, west of Papua New Guinea, north of Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, to the south by Australia and the Indian Ocean; the region is the only part of Asia that lies within the Southern Hemisphere, although the majority of it is in the Northern Hemisphere. In contemporary definition, Southeast Asia consists of two geographic regions: Mainland Southeast Asia known as Indochina, comprising parts of Northeast India, Laos, Thailand and West Malaysia. Maritime Southeast Asia known as Nusantara, the East Indies and Malay Archipelago, comprises the Andaman and Nicobar Islands of India, East Malaysia, the Philippines, East Timor, Christmas Island, the Cocos Islands. Taiwan is included in this grouping by many anthropologists; the region lies near the intersection of geological plates, with both heavy seismic and volcanic activities.
The Sunda Plate is the main plate of the region, featuring all Southeast Asian countries except Myanmar, northern Thailand, northern Laos, northern Vietnam, northern Luzon of the Philippines. The mountain ranges in Myanmar and peninsular Malaysia are part of the Alpide belt, while the islands of the Philippines are part of the Pacific Ring of Fire. Both seismic belts meet in Indonesia, causing the region to have high occurrences of earthquakes and volcanic eruptions. Southeast Asia covers about 4.5 million km2, 10.5% of Asia or 3% of earth's total land area. Its total population is about 8.5 % of the world's population. It is the third most populous geographical region in the world after East Asia; the region is culturally and ethnically diverse, with hundreds of languages spoken by different ethnic groups. Ten countries in the region are members of ASEAN, a regional organization established for economic, military and cultural integration amongst its members; the region, together with part of South Asia, was well known by Europeans as the East Indies or the Indies until the 20th century.
Chinese sources referred the region as 南洋, which means the "Southern Ocean." The mainland section of Southeast Asia was referred to as Indochina by European geographers due to its location between China and the Indian subcontinent and its having cultural influences from both neighboring regions. In the 20th century, the term became more restricted to territories of the former French Indochina; the maritime section of Southeast Asia is known as the Malay Archipelago, a term derived from the European concept of a Malay race. Another term for Maritime Southeast Asia is Insulindia, used to describe the region between Indochina and Australasia; the term "Southeast Asia" was first used in 1839 by American pastor Howard Malcolm in his book Travels in South-Eastern Asia. Malcolm only included the Mainland section and excluded the Maritime section in his definition of Southeast Asia; the term was used in the midst of World War II by the Allies, through the formation of South East Asia Command in 1943.
SEAC popularised the use of the term "Southeast Asia," although what constituted Southeast Asia was not fixed. However, by the late 1970s, a standard usage of the term "Southeast Asia" and the territories it encompasses had emerged. Although from a cultural or linguistic perspective the definitions of "Southeast Asia" may vary, the most common definitions nowadays include the area represented by the countries listed below. Ten of the eleven states of Southeast Asia are members of the Association of Southeast Asian Nations, while East Timor is an observer state. Papua New Guinea has stated that it might join ASEAN, is an observer. Sovereignty issues exist over some territories in the South China Sea; some southern parts of Mainland China, as well as Hong Kong and Taiwan, are considered as part of Southeast Asia by some authors. * Administrative centre in Putrajaya. Southeast Asia is geographically divided into two subregions, namely Mainland Southeast Asia and Maritime Southeast Asia. Mainland Southeast Asia includes: Maritime Southeast Asia includes: The Andaman and Nicobar Islands of India are geographically considered part of Maritime Southeast Asia.
Eastern Bangladesh and Northeast India have strong cultural ties with Southeast Asia and sometimes considered both South Asian and Southeast Asian. Sri Lanka has on some occasions been considered a part of Southeast Asia because of its cultural ties to mainland Southeast Asia; the rest of the island of New Guinea, not part of Indonesia, Papua New Guinea, is sometimes included, so are Palau and the Northern Mariana Islands, which were all part of the Spanish East Indies with strong cultural and linguistic ties to the region the Philippines. The eastern half of Indonesia and East Timor are considered to be biogeographically part of Oceania due to its distinctive faunal features. New Guinea and its surrounding islands are geologically considered as a part of Australian continent, connected via the Sahul Shelf; the region
Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border, its capital is Ottawa, its three largest metropolitan areas are Toronto and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra, its population is urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons. Various indigenous peoples have inhabited what is now Canada for thousands of years prior to European colonization. Beginning in the 16th century and French expeditions explored, settled, along the Atlantic coast.
As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces; this began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster of 1931 and culminated in the Canada Act of 1982, which severed the vestiges of legal dependence on the British parliament. Canada is a parliamentary democracy and a constitutional monarchy in the Westminster tradition, with Elizabeth II as its queen and a prime minister who serves as the chair of the federal cabinet and head of government; the country is a realm within the Commonwealth of Nations, a member of the Francophonie and bilingual at the federal level. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, education.
It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Canada's long and complex relationship with the United States has had a significant impact on its economy and culture. A developed country, Canada has the sixteenth-highest nominal per capita income globally as well as the twelfth-highest ranking in the Human Development Index, its advanced economy is the tenth-largest in the world, relying chiefly upon its abundant natural resources and well-developed international trade networks. Canada is part of several major international and intergovernmental institutions or groupings including the United Nations, the North Atlantic Treaty Organization, the G7, the Group of Ten, the G20, the North American Free Trade Agreement and the Asia-Pacific Economic Cooperation forum. While a variety of theories have been postulated for the etymological origins of Canada, the name is now accepted as coming from the St. Lawrence Iroquoian word kanata, meaning "village" or "settlement".
In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona. Cartier used the word Canada to refer not only to that particular village but to the entire area subject to Donnacona. From the 16th to the early 18th century "Canada" referred to the part of New France that lay along the Saint Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named the Canadas. Upon Confederation in 1867, Canada was adopted as the legal name for the new country at the London Conference, the word Dominion was conferred as the country's title. By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "Realm of the Commonwealth"; the government of Louis St. Laurent ended the practice of using'Dominion' in the Statutes of Canada in 1951. In 1982, the passage of the Canada Act, bringing the Constitution of Canada under Canadian control, referred only to Canada, that year the name of the national holiday was changed from Dominion Day to Canada Day.
The term Dominion was used to distinguish the federal government from the provinces, though after the Second World War the term federal had replaced dominion. Indigenous peoples in present-day Canada include the First Nations, Métis, the last being a mixed-blood people who originated in the mid-17th century when First Nations and Inuit people married European settlers; the term "Aboriginal" as a collective noun is a specific term of art used in some legal documents, including the Constitution Act 1982. The first inhabitants of North America are hypothesized to have migrated from Siberia by way of the Bering land bridge and arrived at least 14,000 years ago; the Paleo-Indian archeological sites at Old Crow Flats and Bluefish Caves are two of the oldest sites of human habitation in Canada. The characteristics of Canadian indigenous societies included permanent settlements, complex societal hierarchies, trading networks; some of these cultures had collapsed by the time European explorers arrived in the late 15th and early 16th centuries and have only been discovered through archeological investigations.
The indigenous population at the time of the first European settlements is estimated to have been between 200,000
A transmission tower or power tower is a tall structure a steel lattice tower, used to support an overhead power line. They are used in high-voltage AC and DC systems, come in a wide variety of shapes and sizes. Typical height ranges from 15 to 55 m, though the tallest are the 370 m towers of a 2,700 m span of Zhoushan Island Overhead Powerline Tie. In addition to steel, other materials may be used, including wood. There are four major categories of transmission towers: suspension, terminal and transposition; some transmission towers combine these basic functions. Transmission towers and their overhead power lines are considered to be a form of visual pollution. Methods to reduce the visual effect include undergrounding. "Transmission tower" is the name for the structure used in the industry in the United States, some other English-speaking countries. The term "pylon" comes from the basic shape of the structure, an obelisk-like structure which tapers toward the top, the name is used in the United Kingdom and parts of Europe in everyday colloquial speech.
This term is used infrequently in the United States, as the word "pylon" is used for many other things for traffic cones. Three-phase electric power systems are used for high voltage and extra-high voltage AC transmission lines; the towers must be designed to carry three conductors. The towers are steel lattices or trusses and the insulators are either glass or porcelain discs or composite insulators using silicone rubber or EPDM rubber material assembled in strings or long rods whose lengths are dependent on the line voltage and environmental conditions. One or two ground wires called "guard" wires, are placed on top to intercept lightning and harmlessly divert it to ground. Towers for high- and extra-high voltage are designed to carry two or more electric circuits. If a line is constructed using towers designed to carry several circuits, it is not necessary to install all the circuits at the time of construction. Indeed, for economic reasons, some transmission lines are designed for three circuits, but only two circuits are installed.
Some high voltage circuits are erected on the same tower as 110 kV lines. Paralleling circuits of 380 kV, 220 kV and 110 kV-lines on the same towers is common. Sometimes with 110 kV circuits, a parallel circuit carries traction lines for railway electrification. High-voltage direct current transmission lines are bipolar systems. With bipolar systems, a conductor arrangement with one conductor on each side of the tower is used. On some schemes, the ground conductor is used as electrode ground return. In this case, it had to be installed with insulators equipped with surge arrestors on the pylons in order to prevent electrochemical corrosion of the pylons. For single-pole HVDC transmission with ground return, towers with only one conductor can be used. In many cases, the towers are designed for conversion to a two-pole system. In these cases conductors on both sides of the tower are installed for mechanical reasons; until the second pole is needed, it is either used as electrode line or joined in parallel with the pole in use.
In the latter case, the line from the converter station to the earthing electrode is built as underground cable, as overhead line on a separate right of way or by using the ground conductors. Electrode line towers are used in some HVDC schemes to carry the power line from the converter station to the grounding electrode, they are similar to structures used for lines with voltages of 10–30 kV, but carry only one or two conductors. Towers used for single-phase AC railway traction lines are similar in construction to those towers used for 110 kV three-phase lines. Steel tube or concrete poles are often used for these lines. However, railway traction current systems are two-pole AC systems, so traction lines are designed for two conductors; these are arranged on one level, whereby each circuit occupies one half of the cross arm. For four traction circuits, the arrangement of the conductors is in two levels and for six electric circuits, the arrangement of the conductors is in three levels. AC circuits of different frequency and phase-count, or AC and DC circuits, may be installed on the same tower.
All circuits of such lines have voltages of 50 kV and more. However, there are some lines of this type for lower voltages. For example, towers used by both railway traction power circuits and the general three-phase AC grid. Two short sections of line carry both AC and DC power circuits. One set of such towers is near the terminal of HVDC Volgograd-Donbass on Volga Hydroelectric Power Station; the other are two towers south of Stenkullen, which carry one circuit of HVDC Konti-Skan and üne circuit of the three-phase AC line Stenkullen-Holmbakullen. Towers carrying AC circuits and DC electrode lines exist in a section of the powerline between Adalph Static Inverter Plant and Brookston the pylons carry the electrode line of HVDC Square Butte; the electrode line of HVDC CU at the converter station at Coal Creek Station uses on a short section the towers of two AC lines as support. The overhead section of the electrode line of Pacific DC Intertie from Sylmar Converter Station to the ground
Ukraine, sometimes called the Ukraine, is a country in Eastern Europe. Excluding Crimea, Ukraine has a population of about 42.5 million, making it the 32nd most populous country in the world. Its capital and largest city is Kiev. Ukrainian is the official language and its alphabet is Cyrillic; the dominant religions in the country are Greek Catholicism. Ukraine is in a territorial dispute with Russia over the Crimean Peninsula, which Russia annexed in 2014. Including Crimea, Ukraine has an area of 603,628 km2, making it the largest country within Europe and the 46th largest country in the world; the territory of modern Ukraine has been inhabited since 32,000 BC. During the Middle Ages, the area was a key centre of East Slavic culture, with the powerful state of Kievan Rus' forming the basis of Ukrainian identity. Following its fragmentation in the 13th century, the territory was contested and divided by a variety of powers, including Lithuania, Austria-Hungary, the Ottoman Empire and Russia. A Cossack republic emerged and prospered during the 17th and 18th centuries, but its territory was split between Poland and the Russian Empire, merged into the Russian-dominated Soviet Union in the late 1940s as the Ukrainian Soviet Socialist Republic.
In 1991 Ukraine gained its independence from the Soviet Union in the aftermath of its dissolution at the end of the Cold War. Before its independence, Ukraine was referred to in English as "The Ukraine", but most sources have since moved to drop "the" from the name of Ukraine in all uses. Following its independence, Ukraine declared itself a neutral state. In 2013, after the government of President Viktor Yanukovych had decided to suspend the Ukraine-European Union Association Agreement and seek closer economic ties with Russia, a several-months-long wave of demonstrations and protests known as the Euromaidan began, which escalated into the 2014 Ukrainian revolution that led to the overthrow of Yanukovych and the establishment of a new government; these events formed the background for the annexation of Crimea by Russia in March 2014, the War in Donbass in April 2014. On 1 January 2016, Ukraine applied the economic component of the Deep and Comprehensive Free Trade Area with the European Union.
Ukraine is ranks 88th on the Human Development Index. As of 2018, Ukraine has the second lowest GDP per capita in Europe. At US$40, it has the lowest median wealth per adult in the world, it suffers from a high poverty rate and severe corruption. However, because of its extensive fertile farmlands, Ukraine is one of the world's largest grain exporters. Ukraine maintains the second-largest military in Europe after that of Russia; the country is home to a multi-ethnic population, 77.8 percent of whom are Ukrainians, followed by a large Russian minority, as well as Georgians, Belarusians, Crimean Tatars, Jews and Hungarians. Ukraine is a unitary republic under a semi-presidential system with separate powers: legislative and judicial branches; the country is a member of the United Nations, the Council of Europe, the OSCE, the GUAM organization, one of the founding states of the Commonwealth of Independent States. There are different hypotheses as to the etymology of the name Ukraine. According to the older widespread hypothesis, it means "borderland", while some more recent linguistic studies claim a different meaning: "homeland" or "region, country"."The Ukraine" used to be the usual form in English, but since the Declaration of Independence of Ukraine, "the Ukraine" has become less common in the English-speaking world, style-guides recommend not using the definite article.
"The Ukraine" now implies disregard for the country's sovereignty, according to U. S. ambassador William Taylor. The Ukrainian position is that the usage of "'The Ukraine' is incorrect both grammatically and politically." Neanderthal settlement in Ukraine is seen in the Molodova archaeological sites which include a mammoth bone dwelling. The territory is considered to be the location for the human domestication of the horse. Modern human settlement in Ukraine and its vicinity dates back to 32,000 BC, with evidence of the Gravettian culture in the Crimean Mountains. By 4,500 BC, the Neolithic Cucuteni–Trypillia culture flourished in wide areas of modern Ukraine including Trypillia and the entire Dnieper-Dniester region. During the Iron Age, the land was inhabited by Cimmerians and Sarmatians. Between 700 BC and 200 BC it was Scythia. Beginning in the sixth century BC, colonies of Ancient Greece, Ancient Rome and the Byzantine Empire, such as Tyras and Chersonesus, were founded on the northeastern shore of the Black Sea.
