Zollverein Coal Mine Industrial Complex
The Zollverein Coal Mine Industrial Complex (German Zeche Zollverein) is a large former industrial site in the city of Essen, North Rhine-Westphalia, Germany. The first coal mine on the premises was founded in 1847, and mining activities took place from 1851 until December 23, 1986. For decades, starting in the late 1950s, the two parts of the site, ''Zollverein Coal Mine'' and ''Zollverein Coking Plant'' (erected 1957−1961, closed on June 30, 1993), ranked among the largest of their kinds in Europe. Shaft 12, built in the New Objectivity style, was opened in 1932 and is considered an architectural and technical masterpiece, earning it a reputation as the "most beautiful coal mine in the world". Because of its architecture and testimony to the development of heavy industry in Europe, the industrial complex was inscribed on the UNESCO World Heritage List on December 14, 2001, and is one of the anchor points of the European Route of Industrial Heritage.

Essen
Essen (; Latin: ''Assindia'') is the central and, after Dortmund, second-largest city of the Ruhr, the largest urban area in Germany. Its population of makes it the fourth-largest city of North Rhine-Westphalia after Cologne, Düsseldorf and Dortmund, as well as the ninth-largest city of Germany. Essen lies in the larger Rhine-Ruhr Metropolitan Region and is part of the cultural area of Rhineland. Because of its central location in the Ruhr, Essen is often regarded as the Ruhr's "secret capital". Two rivers flow through the city: in the north, the Emscher, the Ruhr area's central river, and in the south, the Ruhr River, which is dammed in Essen to form the Lake Baldeney (''Baldeneysee'') and Lake Kettwig (''Kettwiger See'') reservoirs. The central and northern boroughs of Essen historically belong to the Low German ( Westphalian) language area, and the south of the city to the Low Franconian ( Bergish) area (closely related to Dutch). Essen is seat to several of the region' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruhr Area
The Ruhr ( ; german: Ruhrgebiet , also ''Ruhrpott'' ), also referred to as the Ruhr area, sometimes Ruhr district, Ruhr region, or Ruhr valley, is a polycentric urban area in North Rhine-Westphalia, Germany. With a population density of 2,800/km2 and a population of over 5 million (2017), it is the largest urban area in Germany. It consists of several large cities bordered by the rivers Ruhr to the south, Rhine to the west, and Lippe to the north. In the southwest it borders the Bergisches Land. It is considered part of the larger Rhine-Ruhr metropolitan region of more than 10 million people, which is the third largest in Europe, behind only London and Paris.

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low ultimate tensile strength, tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, Prestressed_concrete#Post-tensioned_concrete, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist Tension (physics), tensile Stress (mechanics), stresses in particular regions of the concrete that might cause unacceptable frac ...

Cube
In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Viewed from a corner it is a hexagon and its net is usually depicted as a cross. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices. The cube is also a square parallelepiped, an equilateral cuboid and a right rhombohedron a 3-zonohedron. It is a regular square prism in three orientations, and a trigonal trapezohedron in four orientations. The cube is dual to the octahedron. It has cubical or octahedral symmetry. The cube is the only convex polyhedron whose faces are all squares. Orthogonal projections The ''cube'' has four special orthogonal projections, centered, on a vertex, edges, face and normal to its vertex figure. The first and third correspond to the A2 and B2 Coxeter planes. Spherical tiling The cube can also be represented as a spherical tiling, and p ...

Bauhaus
The Staatliches Bauhaus (), commonly known as the Bauhaus (), was a German art school operational from 1919 to 1933 that combined crafts and the fine arts.Oxford Dictionary of Art and Artists (Oxford: Oxford University Press, 4th edn., 2009), , pp. 64–66 The school became famous for its approach to design, which attempted to unify individual artistic vision with the principles of mass production and emphasis on function. The Bauhaus was founded by architect Walter Gropius in Weimar. It was grounded in the idea of creating a Gesamtkunstwerk ("comprehensive artwork") in which all the arts would eventually be brought together. The Bauhaus style later became one of the most influential currents in modern design, modernist architecture, and architectural education. The Bauhaus movement had a profound influence upon subsequent developments in art, architecture, graphic design, interior design, industrial design, and typography. Staff at the Bauhaus included prominent artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries. Coke may also be formed naturally by geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
