Strelasund Crossing
Strelasund Crossing is the two links to the German island of Rügen (''Rugia'') over the Strelasund to the West Pomeranian mainland near Stralsund: the Rügen Bridge or Rugia Bridge (german: links=no, Rügenbrücke) and the Rugia Causeway (german: links=no, Rügendamm). Ferry services between Stralsund and Altefähr and between Stahlbrode and Glewitz are also available to cross the Strelasund sound. The ''Rügendamm'' was the first fixed crossing over the sound of Strelasund, for both the old Bundesstraße 96, the Stralsund–Sassnitz railway and a combined footpath and cycle path. It was completed 1936/1937. ''Rügenbrücke'' is the name of the three-lane viaduct completed in 2007 exclusively for motor traffic, between the village of Altefähr on Rugia Island and the Hanseatic and world heritage town of Stralsund; as part of the concept to turn the B96 and European route E22 into a ring road. Both bridges are operated in parallel. The Rugia Bridge has an overall lengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesstraße 96 Number
''Bundesstraße'' (German for "federal highway"), abbreviated ''B'', is the denotation for German and Austrian national highways. Germany Germany's ''Bundesstraßen'' network has a total length of about 40,000 km. German ''Bundesstraßen'' are labelled with rectangular yellow signs with black numerals, as opposed to the white-on-blue markers of the ''Autobahn'' controlled-access highways. ''Bundesstraßen'', like autobahns, are maintained by the federal agency of the Transport Ministry. In the German highway system they rank below autobahns, but above the ''Landesstraßen'' and '' Kreisstraßen'' maintained by the federal states and the districts respectively. The numbering was implemented by law in 1932 and has overall been retained up to today, except for those roads located in the former eastern territories of Germany. One distinguishing characteristic between German ''Bundesstraßen'' and ''Autobahnen'' is that there usually is a general 100 km/h (62 mph) sp ...

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galvanized
Galvanization or galvanizing ( also spelled galvanisation or galvanising) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of hot, molten zinc. Protective action The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to the substrate material. History and etymology The earliest known example of galvanized iron was encountered by Europeans on 17th-century Indian armour in the Royal Armouries Museum collection. The term "galvanized" continues to be used metaphorically of any stimulus which results in activity by a person or group of people. In modern usage, the term "galvanizing" has largely come to be associated with zinc coatings, to the exclusion of other metals. Galvanic paint, a pr ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.

Pylon (architecture)
A pylon is a monumental gate of an Egyptian temple (Egyptian: ''bxn.t'' in the Manuel de Codage transliterationErmann & Grapow, ''Wörterbuch der ägyptischen Sprache'', vol.1, 471.9–11). The word comes from the Greek term 'gate'. It consists of two pyramidal towers, each tapered and surmounted by a cornice, joined by a less elevated section enclosing the entrance between them.Toby Wilkinson, ''The Thames and Hudson Dictionary of Ancient Egypt'', Thames & Hudson, 2005. p.195 The gate was generally about half the height of the towers. Contemporary paintings of pylons show them with long poles flying banners. Egyptian architecture In ancient Egyptian religion, the pylon mirrored the hieroglyph ''akhet'' 'horizon', which was a depiction of two hills "between which the sun rose and set". Consequently, it played a critical role in the symbolic architecture of a building associated with the place of re-creation and rebirth. Pylons were often decorated with scenes emphasizing a ...

Deep Foundation
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and caissons. Piles are generally driven into the ground in situ; other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering di ...

Prestressed
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when subj ...
