Omval
Omval is a neighbourhood situated on a peninsula on the eastern shore of the Amstel river in Amsterdam, Netherlands. It is situated south of the Weesperzijde (Amsterdam), Weesperzijde neighbourhood and next to the Amsterdam Amstel railway station in the Submunicipalities of Amsterdam, borough of Amsterdam-Oost. In the 1990s, it became the site of a major business district featuring the Rembrandt Tower, the tallest skyscraper in Amsterdam. History The Omval area became a peninsula in a meander of the Amstel river when the Watergraafsmeer, a polder in the east of the city, was drained and reclaimed in 1629. Originally, the Omval was part of the Ouder-Amstel municipality, but in 1921 the peninsula was added to the city of Amsterdam. The name ''Omval'' refers to the sharp turn in the river Amstel. In order to safely pass this turn, sailboats transporting goods on the river in the 17th century had to Tacking (sailing), tack their sails (''overstag gaan'' or ''omvallen'' in Dutch) to chan ...

Neighbourhood
A neighbourhood (British English, Irish English, Australian English and Canadian English) or neighborhood (American English; see spelling differences) is a geographically localised community within a larger city, town, suburb or rural area, sometimes consisting of a single street and the buildings lining it. Neighbourhoods are often social communities with considerable face-to-face interaction among members. Researchers have not agreed on an exact definition, but the following may serve as a starting point: "Neighbourhood is generally defined spatially as a specific geographic area and functionally as a set of social networks. Neighbourhoods, then, are the spatial units in which face-to-face social interactions occur—the personal settings and situations where residents seek to realise common values, socialise youth, and maintain effective social control." Preindustrial cities In the words of the urban scholar Lewis Mumford, "Neighbourhoods, in some annoying, inchoate f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meander
A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank ( cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain. The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.Neuendorf, K.K.E., J.P.

Guardhouse
A guardhouse (also known as a watch house, guard building, guard booth, guard shack, security booth, security building, or sentry building) is a building used to house personnel and security equipment. Guardhouses have historically been dormitories for sentries or guards, and places where sentries not posted to sentry posts wait "on call", but are more recently staffed by a contracted security company. Some guardhouses also function as jails. Modern guardhouses In 21st century commercial, industrial, institutional, governmental, or residential facilities, Guardhouses are generally placed at the entrance as checkpoints for securing, monitoring and maintaining access control into the secured facility. In the case of small to mid-sized facilities, generally, the entire physical security envelope is controlled from the Guardhouse. One of the general orders of a sentry in the United States Navy and Marine corps is to "Repeat all calls more distant from the guardhouse than my o ...

Cocoa Solids
Dry cocoa solids are the components of cocoa beans remaining after cocoa butter, the fatty component of the bean, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state. Cocoa butter is 46% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa powder is the powdered form of the dry solids with a small remaining amount of cocoa butter. Untreated cocoa powder is bitter and acidic. Dutch process cocoa has been treated with an alkali to neutralize the acid. Cocoa powder contains flavanols, amounts of which are reduced if the cocoa is subjected to acid-reducing alkalization. Physical properties Natural cocoa Natural cocoa powder is extracted with the Broma process where after the cocoa fats have been removed from the chocolate nibs the remaining dry cocoa beans are ground into cocoa powder, which is sold to consumers. Natural cocoa powder has a light-brown color and an extractable pH of 5.3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Amstel In Amsterdam Near Omval
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Light Industry
Light industry are industries that usually are less capital-intensive than heavy industry and are more consumer-oriented than business-oriented, as they typically produce smaller consumer goods. Most light industry products are produced for end users rather than as intermediates for use by other industries. Light industry facilities typically have less environmental impact than those associated with heavy industry. For that reason zoning laws are more likely to permit light industry near residential areas. One definition states that light industry is a "manufacturing activity that uses moderate amounts of partially processed materials to produce items of relatively high value per unit weight". Characteristics Light industries require fewer raw materials, space and power. While light industry typically causes little pollution, particularly compared to heavy industry, some light industry can cause significant pollution or risk of contamination. For example, electronics manuf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Area
Commercial areas in a city are areas, districts, or neighborhoods primarily composed of commercial buildings, such as a strip mall, office parks, downtown, central business district, financial district, " Main Street", or shopping centers. Commercial activity within cities includes the buying and selling of goods and services in retail businesses, wholesale buying and selling, financial establishments, and a wide variety of uses that are broadly classified as "business." While commercial activities typically take up a relatively small amount of land, they are extremely important to a community's economy. They provide employment, facilitate the circulation of money, and often serve many other roles important to the community, such as public gathering and cultural events. A commercial area is real estate intended for use by for-profit businesses, such as office complexes, shopping malls, service stations, bars and restaurants. It may be purchased outright by a developer for futur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willow
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rembrandt
Rembrandt Harmenszoon van Rijn (, ; 15 July 1606 – 4 October 1669), usually simply known as Rembrandt, was a Dutch Golden Age painter, printmaker and draughtsman. An innovative and prolific master in three media, he is generally considered one of the greatest visual artists in the history of art and the most important in Dutch art history.Gombrich, p. 420. Unlike most Dutch masters of the 17th century, Rembrandt's works depict a wide range of style and subject matter, from portraits and self-portraits to landscapes, genre scenes, allegorical and historical scenes, biblical and mythological themes and animal studies. His contributions to art came in a period of great wealth and cultural achievement that historians call the Dutch Golden Age, when Dutch art (especially Dutch painting), whilst antithetical to the Baroque style that dominated Europe, was prolific and innovative. This era gave rise to important new genres. Like many artists of the Dutch Golden Age, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etching
Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. In modern manufacturing, other chemicals may be used on other types of material. As a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today. In a number of modern variants such as microfabrication etching and photochemical milling it is a crucial technique in much modern technology, including circuit boards. In traditional pure etching, a metal plate (usually of copper, zinc or steel) is covered with a waxy ground which is resistant to acid. The artist then scratches off the ground with a pointed etching needle where the artist wants a line to appear in the finished piece, exposing the bare metal. The échoppe, a tool with a slanted oval section, is also used for "swelling" lines. The plate is then dipped in a bath of aci ...

Tacking (sailing)
Tacking is a sailing maneuver by which a sailing vessel, whose desired course is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. The opposite maneuver to tacking is called 'jibe', or 'wearing' on square-rigged ships, that is, turning the stern through the wind. No sailing vessel can move directly upwind, though that may be the desired direction, making this an essential maneuver of a sailing ship. A series of tacking moves, in a zig-zag fashion, is called beating, and allows sailing in the desired direction. This maneuver is used for different effects in races, where one ship is not only sailing in a desired direction, but also concerned with slowing the progress of competitors. The need for tacking Sailing ships cannot proceed directly into the wind, but often need to go in that direction. Movement is achieved by tacking. If a v ...
