Contract bridge
–
Contract bridge, or simply bridge, is a trick-taking game using a standard 52-card deck. It is played by four players in two competing partnerships, with partners sitting opposite each other around a table. Millions of people play bridge worldwide in clubs, tournaments, online and with friends at home, making it one of the worlds most popular card games, particularly among seniors. The World Bridge Federation is the body for international competitive bridge. The game consists of deals, each progressing through four phases. During the auction, partners communicate information about their hand, including its overall strength, the cards are then played, the declaring side trying to fulfill the contract, and the defenders trying to stop the declaring side achieving its goal. The deal is scored based on the number of tricks taken, the contract, one theory is that the name bridge has its origins in the name of an earlier game. Bridge departed from whist with the creation of Biritch in the 19th century, the word biritch itself is a spelling of the Russian word Бирюч, an occupation of a diplomatic clerk or an announcer. However some experts think that the Russian origin of the game is a fallacy, another theory is that British soldiers invented the game bridge while serving in the Crimean War. Bridge is a four-player partnership trick-taking game with thirteen tricks per deal, the dominant variations of the game are rubber bridge, more common in social play, and duplicate bridge, which enables comparative scoring in tournament play. Each player is dealt thirteen cards from a standard 52-card deck, a trick starts when a player leads, i. e. plays the first card. The leader to the first trick is determined by the auction, each player, in a clockwise order, plays one card on the trick. Players must play a card of the suit as the original card led, unless they have none. The player who played the card wins the trick. Within a suit, the ace is ranked highest followed by the king, queen and jack, in a deal where the auction has determined that there is no trump suit, the trick must be won by a card of the suit led. However, in a deal there is a trump suit. If one or more plays a trump to a trick when void in the suit led. For example, if the suit is spades and a player is void in the suit led and plays a spade card

Wiesen Viaduct
–
The Wiesen Viaduct is a single-track railway viaduct, made from concrete blocks with dimension stone coverage. It spans the Landwasser southwest of the hamlet of Wiesen, in the canton of Graubünden, Switzerland. Designed by the chief engineer of the Rhaetian Railway, Henning Friedrich, it was built between 1906 and 1909 by the contractor G. Marasi under the supervision of P. Salaz. The Rhaetian Railway still owns and uses it today for regular service, an important element of the Davos–Filisur railway, the viaduct is 88.9 metres high and 210 metres long, and has a main span of 55 metres. The Wiesen Viaduct forms part of the Davos–Filisur railway section between Wiesen and Filisur, just 300 metres southwest of Wiesen railway station, it has, on its south side, a separate pedestrian bridge giving hikers access to Filisur. At the western end of the viaduct is a non functioning Hippsche turning wheel, the Wiesen Viaduct structure was designed by the then Chief Engineer of the Rhaetian Railway, Henning Friedrich. Construction began in October 1906, under the direction of another engineer, with the launch of the Davos–Filisur railway in July 1909, the viaduct came into operation. It cost a total of 324,000 Swiss francs to build, the falsework used for the building of the viaduct was designed by G. Marasi, swallowed up around 500 cubic metres of wood, and was constructed by the Graubünden carpenter Richard Coray. In 1926, the viaduct was the inspiration for Ernst Ludwig Kirchners painting Brücke bei Wiesen, the Wiesen Viaduct is 88.9 metres high and 210 metres long. Its main span is only 3.7 metres wide, but also 55 metres long, to the west of the main span are two arches, each 20 metres long. East of the span are four more arches, each of them also 20 metres long. These technical characteristics combine to make the Wiesen Viaduct the Rhaetian Railways largest stone, bernina Express Arch bridge See the references in Wiesener Viadukt Wiesener Viadukt

Body of water
–
A body of water or waterbody is any significant accumulation of water, generally on a planets surface. The term most often refers to oceans, seas, and lakes, a body of water does not have to be still or contained, Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. Most are naturally occurring geographical features, but some are artificial, there are types that can be either. For example, most reservoirs are created by engineering dams, similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways, some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans. The term body of water can also refer to a reservoir of water held by a plant, note that there are some geographical features involving water that are not bodies of water, for example waterfalls, geysers and rapids. Arm of the sea - also sea arm, used to describe a sea loch, arroyo - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, or seasonally. Artificial lake or artificial pond - see reservoir or impoundment, barachois - a lagoon separated from the ocean by a sand bar. Bay - an area of water bordered by land on three sides, similar to, but smaller than a gulf, bayou - a slow-moving stream or a marshy lake. Bight - a large and often only slightly receding bay, or a bend in any geographical feature, billabong - see Oxbow lake, a pond or still body of water created when a river changes course and some water becomes trapped. Boil - see Seep Brook - a small stream, canal - an artificial waterway, usually connected to existing lakes, rivers, or oceans. Channel - the physical confine of a river, slough or ocean consisting of a bed. See also stream bed and strait, earth scientists generally use the term to describe a circular or round inlet with a narrow entrance, though colloquially the term is sometimes used to describe any sheltered bay. Basin - a region of land where water from rain or snowmelt drains downhill into another body of water, such as a river, lake, creek - an inlet of the sea, narrower than a cove. Delta - the location where a river flows into an ocean, sea, estuary, lake, distributary or distributary channel - a stream that branches off and flows away from a main stream channel. Draw - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, fjord - a submergent landform which has occurred due to glacial activity. Glacier - a large collection of ice or a river that moves slowly down a mountain. Glacial Pothole - see Kettle Gulf - a part of a lake or ocean that extends so that it is surrounded by land on three sides, similar to, but larger than a bay, headland - an area of water bordered by land on three sides

Valley
–
A valley is a low area between hills, often with a river running through it. In geology, a valley or dale is a depression that is longer than it is wide, the terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of two main types or a mixture of them, with respect to the cross section of the slopes or hillsides. A valley in its broadest geographic sense is known as a dale. A valley through which a river runs may also be referred to as a vale, a small, secluded, and often wooded valley is known as a dell or in Scotland as a glen. A wide, flat valley through which a river runs is known in Scotland as a strath, a mountain cove is a small valley, closed at one or both ends, in the central or southern Appalachian Mountains which sometimes results from the erosion of a geologic window. A small valley surrounded by mountains or ridges is sometimes known as a hollow, a deep, narrow valley is known as a cwm. Similar geological structures, such as canyons, ravines, gorges, gullies, chines, a valley formed by erosion is called an erosional valley, a valley formed by geologic events such as drop faults or the rise of highlands is called a structural valley. A valley formed by flowing water, or river valley, is usually V-shaped, the exact shape will depend on the characteristics of the stream flowing through it. Rivers with steep gradients, as in mountain ranges, produce steep walls, shallower slopes may produce broader and gentler valleys. However, in the lowest stretch of a river, where it approaches its base level, it begins to deposit sediment, in prehistory, the rivers were used as a source of fresh water and food, as well as a place to wash and a sewer. The proximity of water moderated temperature extremes and provided a source for irrigation, most of the first civilizations developed from these river valley communities. In geography, a vale is a river valley, usually with a particularly wide flood plain or flat valley bottom. In Southern England, vales commonly occur between the escarpment slopes of pairs of chalk formations, where the dome has been eroded, exposing less resistant underlying rock. Rift valleys, such as the Albertine Rift, are formed by the expansion of the Earths crust due to tectonic activity beneath the Earths surface, there are various forms of valley associated with glaciation that may be referred to as glacial valleys. A valley carved by glaciers is normally U-shaped, the valley becomes visible upon the recession of the glacier that forms it. When the ice recedes or thaws, the remains, often littered with small boulders that were transported within the ice. Floor gradient does not affect the shape, it is the glaciers size that does

Road
–
Roads consist of one or two roadways, each with one or more lanes and any associated sidewalks and road verges. Roads that are available for use by the public may be referred to as parkways, avenues, freeways, interstates, highways, or primary, secondary, and tertiary local roads. In urban areas roads may diverge through a city or village and be named as streets, serving a function as urban space easement. Modern roads are normally smoothed, paved, or otherwise prepared to allow easy travel, historically many roads were simply recognizable routes without any formal construction or maintenance. In the United Kingdom there is ambiguity between the terms highway and road. The Highway code details rules for road users and this includes footpaths, bridleways and cycle tracks, and also road and driveways on private land and many car parks. Vehicle Excise Duty, a use tax, is payable on some vehicles used on the public road. The definition of a road depends on the definition of a highway, in the United States, laws distinguish between public roads, which are open to public use, and private roads, which are privately controlled. The assertion that the first pathways were the trails made by animals has not been universally accepted, others believe that some roads originated from following animal trails. The Icknield Way is given as an example of type of road origination. By about 10,000 BC, rough roads/pathways were used by human travelers, the worlds oldest known paved road was constructed in Egypt some time between 2600 and 2200 BC. Stone-paved streets are found in the city of Ur in the Middle East dating back to 4000 BC, corduroy roads are found dating to 4000 BC in Glastonbury, England. The Sweet Track, a timber causeway in England, is one of the oldest engineered roads discovered. Built in winter 3807 BC or spring 3806 BC, tree-ring dating enabled very precise dating and it was claimed to be the oldest road in the world until the 2009 discovery of a 6, 000-year-old trackway in Plumstead, London. Brick-paved streets were used in India as early as 3000 BC, in 500 BC, Darius I the Great started an extensive road system for Persia, including the Royal Road, which was one of the finest highways of its time. The road remained in use after Roman times, a hybrid of road transport and ship transport beginning in about 1740 is the horse-drawn boat in which the horse follows a cleared path along the river bank. From about 312 BC, the Roman Empire built straight strong stone Roman roads throughout Europe and North Africa, at its peak the Roman Empire was connected by 29 major roads moving out from Rome and covering 78,000 kilometers or 52,964 Roman miles of paved roads. In the 8th century AD, many roads were built throughout the Arab Empire, the most sophisticated roads were those in Baghdad, which were paved with tar

Terrain
–
Terrain or relief is the vertical and horizontal dimension of the land surface. When relief is described underwater, the term bathymetry is used, the Latin Word Terra, is Earth. Terrain is used as a term in physical geography, referring to the lay of the land. This is usually expressed in terms of the elevation, slope, terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns, complex arrays of relief data are used as input parameters for hydrology transport models to allow prediction of river water quality. Understanding terrain also supports soil conservation, especially in agriculture, contour ploughing is an established practice enabling sustainable agriculture on sloping land, it is the practice of ploughing along lines of equal elevation instead of up and down a slope. Terrain is militarily critical because it determines the ability of armed forces to take and hold areas, an understanding of terrain is basic to both defensive and offensive strategy. Terrain is important in determining weather patterns, two areas geographically close to each other may differ radically in precipitation levels or timing because of elevation differences or a rain shadow effect. Precise knowledge of terrain is vital in aviation, especially for low-flying routes and maneuvers, terrain will also affect range and performance of radars and terrestrial radio navigation systems. Furthermore, a hilly or mountainous terrain can strongly impact the implementation of a new aerodrome, relief refers specifically to the quantitative measurement of vertical elevation change in a landscape. It is the difference between maximum and minimum elevations within an area, usually of limited extent. The relief of a landscape can change with the size of the area over which it is measured, making the definition of the scale over which it is measured very important. Because it is related to the slope of surfaces within the area of interest and to the gradient of any streams present, the relief of a landscape is a useful metric in the study of the Earths surface. Relief energy, which may be defined inter alia as the height range in a regular grid, is essentially an indication of the ruggedness or relative height of the terrain. Geomorphology is in part the study of the formation of terrain or topography. Terrain is formed by intersecting processes, Geological processes, Migration of tectonic plates, faulting and folding, volcanic eruptions, erosional processes, water and wind erosion, landslides. Tectonic processes such as orogenies cause land to be elevated, land surface parameters are quantitative measures of various morphometric properties of a surface. The most common examples are used to derive slope or aspect of a terrain or curvatures at each location and these measures can also be used to derive hydrological parameters that reflect flow/erosion processes

Japan
–
Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon

Zayanderud
–
Zāyandé-Rūd or Zāyanderūd, also spelled as Zayandeh-Rood or Zayanderood, is the largest river of the Iranian Plateau in central Iran. The Zayandeh starts in the Zard-Kuh subrange of the Zagros Mountains in Chaharmahal and it flows 400 kilometres eastward before ending in the Gavkhouni swamp, a seasonal salt lake, southeast of Isfahan city. The Zayandeh used to have significant flow all year long, unlike many of Irans rivers which are seasonal, in the early 2010s, the lower reaches of the river dried out completely after several years of seasonal dry-outs. Zayandeh River water gave life to the people of central Iran mainly in Isfahan, before the drying-out, water diverted per person was 240 litres per day in urban areas and 150 litres per day in villages. In the 1970s, the flow of the river was estimated at 1.2 cubic kilometres per annum, people have lived on the banks of Zayandeh River for thousands of years. The earliest evidence of occupation along the River is found in a cave site called Qaleh Bozi near Dizicheh at SW of Isfahan. More than 40,000 years ago, groups of Paleolithic hunters used Qaleh Bozi caves as shelter for seasonal or temporary occupations and left their stone tools, an ancient prehistoric culture, the Zayandeh River Civilization, flourished along the banks of the Zayandeh in the 6th Millennium BC. Zayandeh River crosses the city of Isfahan, a major cultural, in the 17th century, Shaikh Bahai, designed and built a system of canals, to distribute Zayandeh water to Isfahans suburbs. The Zayandeh river bed is spanned by many historical Safavid era bridges, arthur Pope and his wife Phyllis Ackerman are buried in a small tomb in pleasant surroundings in its banks. Richard Frye has also requested to be buried there, until the 1960s in Isfahan Province the distribution of water followed the Tomar, a document claimed to date from the 16th Century. The Tomar divided the flow of the Zayandeh River into 33 parts which were then allotted to the eight major districts within the region. At the district level the water flow was divided either on a basis, or by the use of variable weirs. For centuries Isfahan city had been a settlement, noted for its surrounding fertile lands. Until the 1960s industrial demand for water was minimal, which enabled the water resources to be utilized primarily for agriculture. The creation of steel works and other new industries demanded water. The Chadegan Reservoir dam project in 1972 was a hydroelectric project to help with stabilizing water flow. The dam was initially named Shah Abbas Dam after Shah Abbas I, the most influential king of the Safavid dynasty, since 1972, the Chadegan Reservoir has helped prevent seasonal flooding of the Zayandeh River. Water discharge is increased during Persian New Year to allow the river to flow through Esfahan once more during the public holiday, 80% of the Zayandehs extracted water is used for agriculture, 10% for human consumption, 7% for industry and 3% for other uses

Safavid dynasty
–
The Safavid dynasty was one of the most significant ruling dynasties of Iran, often considered the beginning of modern Iranian history. The Safavid shahs ruled over one of the so-called gunpowder empires, the Safavid dynasty had its origin in the Safaviyya Sufi order, which was established in the city of Ardabil in the Azerbaijan region. The Safavids have also left their mark down to the present era by spreading Shia Islam in Iran, as well as parts of the Caucasus, Anatolia. The Safavid Kings themselves claimed to be Seyyeds, family descendants of the Islamic prophet Muhammad, There seems now to be a consensus among scholars that the Safavid family hailed from Persian Kurdistan, and later moved to Azerbaijan, finally settling in the 11th century CE at Ardabil. Traditional pre-1501 Safavid manuscripts trace the lineage of the Safavids to the Kurdish dignitary, a massive migration of Oghuz Turks in the 11th and 12th centuries not only Turkified Azerbaijan but also Anatolia. The Azeri Turks are Shiʿites and were founders of the Safavid dynasty, by the time of the establishment of the Safavid empire, the members of the family were native Turkish-speaking and Turkicized, and some of the Shahs composed poems in their native Turkish language. Furthermore, the dynasty was from the very start thoroughly intermarried with both Pontic Greek as well as Georgian lines, Safavid history begins with the establishment of the Safaviyya by its eponymous founder Safi-ad-din Ardabili. In 700/1301, Safi al-Din assumed the leadership of the Zahediyeh, due to the great spiritual charisma of Safi al-Din, the order was later known as the Safaviyya. The Safavid order soon gained great influence in the city of Ardabil, after Safī al-Dīn, the leadership of the Safaviyya passed to Sadr al-Dīn Mūsā. The leadership of the order passed from Sadr ud-Dīn Mūsā to his son Khwādja Ali, when Shaykh Junayd, the son of Ibrāhim, assumed the leadership of the Safaviyya in 1447, the history of the Safavid movement was radically changed. Savory, Sheikh Junayd was not content with spiritual authority and he sought material power, Junayd sought refuge with the rival of Kara Koyunlu Jahan Shah, the Aq Qoyunlu Khan Uzun Hassan, and cemented his relationship by marrying Uzun Hassans sister, Khadija Begum. Junayd was killed during an incursion into the territories of the Shirvanshah and was succeeded by his son Haydar Safavi, Haydar married Martha Alamshah Begom, Uzun Hassans daughter, who gave birth to Ismail I, founder of the Safavid dynasty. Marthas mother Theodora—better known as Despina Khatun—was a Pontic Greek princess and she had been married to Uzun Hassan in exchange for protection of the Grand Komnenos from the Ottomans. After Uzun Hassans death, his son Yaqub felt threatened by the growing Safavid religious influence, Yaqub allied himself with the Shirvanshah and killed Haydar in 1488. By this time, the bulk of the Safaviyya were nomadic Oghuz Turkic-speaking clans from Asia Minor, the Qizilbash were warriors, spiritual followers of Haydar, and a source of the Safavid military and political power. After the death of Haydar, the Safaviyya gathered around his son Ali Mirza Safavi, according to official Safavid history, before passing away, Ali had designated his young brother Ismail as the spiritual leader of the Safaviyya. After the decline of the Timurid Empire, Persia was politically splintered, the demise of Tamerlanes political authority created a space in which several religious communities, particularly Shi’i ones, could come to the fore and gain prominence. Among these were a number of Sufi brotherhoods, the Hurufis, Nuqtawis, of these various movements, the Safavid Qizilbash was the most politically resilient, and due to its success Shah Isma’il I gained political prominence in 1501

Isfahan
–
Isfahan, historically also rendered in English as Ispahan, Sepahan, Esfahan or Hispahan, is the capital of Isfahan Province in Iran, located about 340 kilometres south of Tehran. The Greater Isfahan Region had a population of 3,793,104 in the 2011 Census, the counties of Isfahan, Borkhar, Najafabad, Khomeynishahr, Shahinshahr, Mobarakeh, Falavarjan, Tiran o Karvan, Lenjan and Jay all constitute the metropolitan city of Isfahan. Isfahan is located on the main north–south and east–west routes crossing Iran and it flourished from 1050 to 1722, particularly in the 16th and 17th centuries under the Safavid dynasty, when it became the capital of Persia for the second time in its history. Even today, the city retains much of its past glory and it is famous for its Persian–Islamic architecture, with many beautiful boulevards, covered bridges, palaces, mosques, and minarets. This led to the Persian proverb Esfahān nesf-e- jahān ast, the Naghsh-e Jahan Square in Isfahan is one of the largest city squares in the world. It has been designated by UNESCO as a World Heritage Site, the city also has a wide variety of historic monuments and is known for the paintings, history and architecture. Isfahan City Center is also the 5th largest shopping mall in the world, see also, Names of Isfahan The name of the region derives from Middle Persian Spahān. Spahān is attested in various Middle Persian seals and inscriptions, including that of Zoroastrian Magi Kartir, the present-day name is the Arabicized form of Ispahan. The region appears with the abbreviation GD on Sasanian numismatics, in Ptolemys Geographia it appears as Aspadana, translating to place of gathering for the army. It is believed that Spahān derives from spādānām the armies, Old Persian plural of spāda, the history of Isfahan can be traced back to the Palaeolithic period. In recent discoveries, archaeologists have found artifacts dating back to the Palaeolithic, Mesolithic, Neolithic, Bronze and Iron ages. It is said that after Cyrus the Great freed the Jews from Babylon some Jews returned to Jerusalem whereas some others decided to live in Persia, but, actually this happened later in the Sasanid period when a Jewish colony was made in the vicinity of the Sasanid. They did not settle anywhere or in any city without examining the water. They did all along until they reached the city of Isfahan, there they rested, examined the water and soil and found that both resembled Jerusalem. Upon they settled there, cultivated the soil, raised children and grandchildren, under the Parthians, Arsacid governors administered a large province from Isfahan, and the citys urban development accelerated to accommodate the needs of a capital city. The next empire to rule Persia, the Sassanids, presided over changes in their realm, instituting sweeping agricultural reform and reviving Iranian culture. The city was called by the name and the region by the name Aspahan or Spahan. The city was governed by Espoohrans or the members of seven noble Iranian families who had important royal positions, extant foundations of some Sassanid-era bridges in Isfahan suggest that the kings were also fond of ambitious urban planning projects

Iran
–
Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Oxford English Dictionary
–
The Oxford English Dictionary is a descriptive dictionary of the English language, published by the Oxford University Press. The second edition came to 21,728 pages in 20 volumes, in 1895, the title The Oxford English Dictionary was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in ten bound volumes. In 1933, the title The Oxford English Dictionary fully replaced the name in all occurrences in its reprinting as twelve volumes with a one-volume supplement. More supplements came over the years until 1989, when the edition was published. Since 2000, an edition of the dictionary has been underway. The first electronic version of the dictionary was available in 1988. The online version has been available since 2000, and as of April 2014 was receiving two million hits per month. The third edition of the dictionary will probably appear in electronic form, Nigel Portwood, chief executive of Oxford University Press. As a historical dictionary, the Oxford English Dictionary explains words by showing their development rather than merely their present-day usages, therefore, it shows definitions in the order that the sense of the word began being used, including word meanings which are no longer used. The format of the OEDs entries has influenced numerous other historical lexicography projects and this influenced later volumes of this and other lexicographical works. As of 30 November 2005, the Oxford English Dictionary contained approximately 301,100 main entries, the dictionarys latest, complete print edition was printed in 20 volumes, comprising 291,500 entries in 21,730 pages. The longest entry in the OED2 was for the verb set, as entries began to be revised for the OED3 in sequence starting from M, the longest entry became make in 2000, then put in 2007, then run in 2011. Despite its impressive size, the OED is neither the worlds largest nor the earliest exhaustive dictionary of a language, the Dutch dictionary Woordenboek der Nederlandsche Taal is the worlds largest dictionary, has similar aims to the OED and took twice as long to complete. Another earlier large dictionary is the Grimm brothers dictionary of the German language, begun in 1838, the official dictionary of Spanish is the Diccionario de la lengua española, and its first edition was published in 1780. The Kangxi dictionary of Chinese was published in 1716, trench suggested that a new, truly comprehensive dictionary was needed. On 7 January 1858, the Society formally adopted the idea of a new dictionary. Volunteer readers would be assigned particular books, copying passages illustrating word usage onto quotation slips, later the same year, the Society agreed to the project in principle, with the title A New English Dictionary on Historical Principles. He withdrew and Herbert Coleridge became the first editor, on 12 May 1860, Coleridges dictionary plan was published and research was started

Old English
–
Old English or Anglo-Saxon is the earliest historical form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlers probably in the mid 5th century, Old English developed from a set of Anglo-Frisian or North Sea Germanic dialects originally spoken by Germanic tribes traditionally known as the Angles, Saxons, and Jutes. As the Anglo-Saxons became dominant in England, their language replaced the languages of Roman Britain, Common Brittonic, a Celtic language, Old English had four main dialects, associated with particular Anglo-Saxon kingdoms, Mercian, Northumbrian, Kentish and West Saxon. It was West Saxon that formed the basis for the standard of the later Old English period, although the dominant forms of Middle. The speech of eastern and northern parts of England was subject to strong Old Norse influence due to Scandinavian rule, Old English is one of the West Germanic languages, and its closest relatives are Old Frisian and Old Saxon. Like other old Germanic languages, it is different from Modern English. Old English grammar is similar to that of modern German, nouns, adjectives, pronouns, and verbs have many inflectional endings and forms. The oldest Old English inscriptions were using a runic system. Old English was not static, and its usage covered a period of 700 years, from the Anglo-Saxon settlement of Britain in the 5th century to the late 11th century, some time after the Norman invasion. While indicating that the establishment of dates is a process, Albert Baugh dates Old English from 450 to 1150, a period of full inflections. Perhaps around 85 per cent of Old English words are no longer in use, Old English is a West Germanic language, developing out of Ingvaeonic dialects from the 5th century. It came to be spoken over most of the territory of the Anglo-Saxon kingdoms which became the Kingdom of England and this included most of present-day England, as well as part of what is now southeastern Scotland, which for several centuries belonged to the Anglo-Saxon kingdom of Northumbria. Other parts of the island – Wales and most of Scotland – continued to use Celtic languages, Norse was also widely spoken in the parts of England which fell under Danish law. Anglo-Saxon literacy developed after Christianisation in the late 7th century, the oldest surviving text of Old English literature is Cædmons Hymn, composed between 658 and 680. There is a corpus of runic inscriptions from the 5th to 7th centuries. The Old English Latin alphabet was introduced around the 9th century, with the unification of the Anglo-Saxon kingdoms by Alfred the Great in the later 9th century, the language of government and literature became standardised around the West Saxon dialect. In Old English, typical of the development of literature, poetry arose before prose, a later literary standard, dating from the later 10th century, arose under the influence of Bishop Æthelwold of Winchester, and was followed by such writers as the prolific Ælfric of Eynsham. This form of the language is known as the Winchester standard and it is considered to represent the classical form of Old English

Arkadiko Bridge
–
The Arkadiko Bridge or Kazarma Bridge is a Mycenaean bridge near the modern road from Tiryns to Epidauros on the Peloponnese, Greece. Dating to the Greek Bronze Age, it is one of the oldest arch bridges still in existence, the corbel arch bridge belonged in Mycenaean times to a highway between the two cities, which formed part of a wider military road network. It has a span of ca.1 m and is made in the typical Mycenaean manner of Cyclopean stones. The structure is 22 metres long,5.60 metres wide at the base and 4 metres high, the width of the roadway atop is about 2.50 metres. The sophisticated layout of the bridge and the road indicate that they were constructed for use by chariots. Built in the late Late Helladic III, the bridge is used by the local populace. The Arkadiko Bridge is one of four known Mycenaean corbel arch bridges near Arkadiko. One of them is the Petrogephyri bridge, which crosses the same stream 1 km to the west of the Arkadiko bridge, otherwise similar in size and appearance, the structure has a larger span and a little higher vault. It, too, is used as a local track. A fifth, well-preserved Mycenaean bridge is located in the region at Lykotroupi. Its measurements are close to the Arkadiko Bridge,5.20 metres wide at the bottom,2.40 metres at the top, the road still features curbs for guiding fast-moving chariots. Hope Simpson, D. K.

Greece
–
Greece, officially the Hellenic Republic, historically also known as Hellas, is a country in southeastern Europe, with a population of approximately 11 million as of 2015. Athens is the capital and largest city, followed by Thessaloniki. Greece is strategically located at the crossroads of Europe, Asia, situated on the southern tip of the Balkan peninsula, it shares land borders with Albania to the northwest, the Republic of Macedonia and Bulgaria to the north, and Turkey to the northeast. Greece consists of nine regions, Macedonia, Central Greece, the Peloponnese, Thessaly, Epirus, the Aegean Islands, Thrace, Crete. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, the Cretan Sea and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin and the 11th longest coastline in the world at 13,676 km in length, featuring a vast number of islands, eighty percent of Greece is mountainous, with Mount Olympus being the highest peak at 2,918 metres. From the eighth century BC, the Greeks were organised into various independent city-states, known as polis, which spanned the entire Mediterranean region and the Black Sea. Greece was annexed by Rome in the second century BC, becoming a part of the Roman Empire and its successor. The Greek Orthodox Church also shaped modern Greek identity and transmitted Greek traditions to the wider Orthodox World, falling under Ottoman dominion in the mid-15th century, the modern nation state of Greece emerged in 1830 following a war of independence. Greeces rich historical legacy is reflected by its 18 UNESCO World Heritage Sites, among the most in Europe, Greece is a democratic and developed country with an advanced high-income economy, a high quality of life, and a very high standard of living. A founding member of the United Nations, Greece was the member to join the European Communities and has been part of the Eurozone since 2001. Greeces unique cultural heritage, large industry, prominent shipping sector. It is the largest economy in the Balkans, where it is an important regional investor, the names for the nation of Greece and the Greek people differ from the names used in other languages, locations and cultures. The earliest evidence of the presence of human ancestors in the southern Balkans, dated to 270,000 BC, is to be found in the Petralona cave, all three stages of the stone age are represented in Greece, for example in the Franchthi Cave. Neolithic settlements in Greece, dating from the 7th millennium BC, are the oldest in Europe by several centuries and these civilizations possessed writing, the Minoans writing in an undeciphered script known as Linear A, and the Mycenaeans in Linear B, an early form of Greek. The Mycenaeans gradually absorbed the Minoans, but collapsed violently around 1200 BC and this ushered in a period known as the Greek Dark Ages, from which written records are absent. The end of the Dark Ages is traditionally dated to 776 BC, the Iliad and the Odyssey, the foundational texts of Western literature, are believed to have been composed by Homer in the 7th or 8th centuries BC. With the end of the Dark Ages, there emerged various kingdoms and city-states across the Greek peninsula, in 508 BC, Cleisthenes instituted the worlds first democratic system of government in Athens

Arch bridge
–
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, a viaduct may be made from a series of arches, although other more economical structures are typically used today. Possibly the oldest existing bridge is the Mycenaean Arkadiko bridge in Greece from about 1300 BC. The stone corbel arch bridge is used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch, a more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 different countries. Roman arch bridges were usually semicircular, although a number were segmental arch bridges, generally, Roman bridges featured wedge-shaped primary arch stones of the same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts, such as the Pont du Gard and Segovia Aqueduct. Their bridges featured from an early time onwards flood openings in the piers, e. g. in the Pons Fabricius in Rome, Roman engineers were the first and until the industrial revolution the only ones to construct bridges with concrete, which they called Opus caementicium. The outside was covered with brick or ashlar, as in the Alcántara bridge. The Romans also introduced segmental arch bridges into bridge construction, trajans bridge over the Danube featured open-spandrel segmental arches made of wood. This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m long Puente Romano at Mérida. The late Roman Karamagara Bridge in Cappadocia may represent the earliest surviving bridge featuring a pointed arch, in medieval Europe, bridge builders improved on the Roman structures by using narrower piers, thinner arch barrels and lower span-rise ratios on bridges. Gothic pointed arches were introduced, reducing lateral thrust. The 14th century in particular saw bridge building reaching new heights, the bridge at Trezzo sullAdda, destroyed in the 15th century, even featured a span length of 72 m, not matched until 1796. Constructions such as the acclaimed Florentine segmental arch bridge Ponte Vecchio combined sound engineering with aesthetical appeal, the three elegant arches of the Renaissance Ponte Santa Trinita constitute the oldest elliptic arch bridge worldwide. In China, the oldest existing bridge is the Zhaozhou Bridge of 605 AD. The Zhaozhou Bridge, with a length of 167 feet and span of 123 feet, is the worlds first wholly stone open-spandrel segmental arch bridge, Bridges with perforated spandrels can be found worldwide, such as in China

Amsterdam
–
Amsterdam is the capital and most populous municipality of the Kingdom of the Netherlands. Its status as the capital is mandated by the Constitution of the Netherlands, although it is not the seat of the government, which is The Hague. Amsterdam has a population of 851,373 within the city proper,1,351,587 in the urban area, the city is located in the province of North Holland in the west of the country. The metropolitan area comprises much of the part of the Randstad, one of the larger conurbations in Europe. Amsterdams name derives from Amstelredamme, indicative of the citys origin around a dam in the river Amstel, during that time, the city was the leading centre for finance and diamonds. In the 19th and 20th centuries the city expanded, and many new neighborhoods and suburbs were planned, the 17th-century canals of Amsterdam and the 19–20th century Defence Line of Amsterdam are on the UNESCO World Heritage List. As the commercial capital of the Netherlands and one of the top financial centres in Europe, Amsterdam is considered a world city by the Globalization. The city is also the capital of the Netherlands. Many large Dutch institutions have their headquarters there, and seven of the worlds 500 largest companies, including Philips and ING, are based in the city. In 2012, Amsterdam was ranked the second best city to live in by the Economist Intelligence Unit and 12th globally on quality of living for environment, the city was ranked 3rd in innovation by Australian innovation agency 2thinknow in their Innovation Cities Index 2009. The Amsterdam seaport to this day remains the second in the country, famous Amsterdam residents include the diarist Anne Frank, artists Rembrandt van Rijn and Vincent van Gogh, and philosopher Baruch Spinoza. The Amsterdam Stock Exchange, the oldest stock exchange in the world, is located in the city center. After the floods of 1170 and 1173, locals near the river Amstel built a bridge over the river, the earliest recorded use of that name is in a document dated October 27,1275, which exempted inhabitants of the village from paying bridge tolls to Count Floris V. This allowed the inhabitants of the village of Aemstelredamme to travel freely through the County of Holland, paying no tolls at bridges, locks, the certificate describes the inhabitants as homines manentes apud Amestelledamme. By 1327, the name had developed into Aemsterdam, Amsterdam is much younger than Dutch cities such as Nijmegen, Rotterdam, and Utrecht. In October 2008, historical geographer Chris de Bont suggested that the land around Amsterdam was being reclaimed as early as the late 10th century. This does not necessarily mean there was already a settlement then, since reclamation of land may not have been for farming—it may have been for peat. Amsterdam was granted city rights in either 1300 or 1306, from the 14th century on, Amsterdam flourished, largely from trade with the Hanseatic League

The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

Corbel arch
–
A corbel vault uses this technique to support the superstructure of a buildings roof. For a corbeled vault covering the technique is extended in three dimensions along the lengths of two opposing walls, unlike true arches, not all of the structures tensile stresses caused by the weight of the superstructure are transformed into compressive stresses. The Newgrange passage tomb has a corbel arch supporting the roof of the main chamber. Egyptian pyramids from around the time of Sneferu used corbel vaults in some of their chambers and these include the Bent Pyramid and the Red Pyramid. Corbel arches and vaults are found in places around the ancient Mediterranean. In particular, corbelled burial vaults constructed below the floor are found in Ebla in Syria, and in Tel Hazor, nuraghe constructions in ancient Sardinia, dating back to 1900 BC, use similar corbel techniques. The use of Beehive tombs on the Iberian peninsula and elsewhere around the Mediterranean, the Hittites in ancient Anatolia were also building corbelled vaults. The earliest ones date to the 16th century BC, some similarities are found between the Hittite and Mycenaean construction techniques. Yet the Hittite corbelled vaults are earlier by about 300 years, the ruins of ancient Mycenae feature many corbel arches and vaults, the Treasury of Atreus being a prominent example. Dating to the Greek Bronze Age, it is one of the oldest arch bridges still in existence, the well-preserved hellenistic Eleutherna Bridge on Crete has an unusually large span of nearly 4 m. Corbeled arches are a feature of certain pre-Columbian Mesoamerican constructions and historical/regional architectural styles. By the beginning of the Classic era corbeled vaults are a feature of building construction in the central Petén Basin region of the central Maya lowlands. Before the true arch was introduced by the Mughals, the arches in Indian buildings were trabeated or corbelled, the tomb of Sultan Ghari is an example of a corbelled arch from 1231 AD, located in New Delhi, India. The candi or temples of Indonesia which are constructed between 8th to 15th century, are made use of corbel arch technique to create an opening for gate or inner chamber of the temple. The notable example of corbel arch in Indonesian classic temple architecture is the arches of Borobudur, the interlocking andesite stone blocks creating the corbel arch, is notable for its T formed lock on the center top of the corbel arch. All the temples in Angkor made use of the corbel arch, Beehive house Beehive tomb Catenary arch Corbelling Parabolic arch Coe, Michael D.
