Nijmegen Railway Bridge
The Nijmegen railway bridge is a truss bridge spanning the River Waal, connecting the city of Nijmegen to the town of Lent in the Netherlands. Construction Construction started in 1875, on the site of an ancient Roman bridge, and was completed 4 years later in 1879. It originally consisted of 3 truss arches. The southern land abutment, styled as a medieval city gate, was designed by Dutch architect P.J.H Cuypers. These tower structures served the purposes of protecting the entrance to the city of Nijmegen. The railway bridge's construction meant that train connections to Arnhem were possible, thus Nijmegen was the last major city in the Netherlands to be connected to the national rail network. Second World War The middle arch of the bridge was destroyed twice during the Second World War, but despite this it survived the conflict. The first demolition was initiated on 10 May 1940 by the Dutch themselves when the Wehrmacht approached. The Germans repaired the bridge, and it ...

Waal (river)
The Waal ( Dutch name, ) is the main distributary branch of the river Rhine flowing approximately through the Netherlands. It is the major waterway connecting the port of Rotterdam to Germany. Before it reaches Rotterdam, it joins with the Afgedamde Maas near Woudrichem to form the Boven Merwede. Along its length, Nijmegen, Tiel, Zaltbommel and Gorinchem are towns of importance with direct access to the river. The river, which is the main channel in the Rhine–Meuse–Scheldt delta system, carries 65% of the total flow of the Rhine. History The name Waal, in Roman times called ''Vacalis, Vahalis'' or ''Valis'', later ''Vahal'', is of Germanic origin and is named after the many meanders in the river ( gmw, wôh, lit=crooked). It is, in turn, thought to have inspired early Dutch settlers of the Hudson Valley region in New York to name the Wallkill River after it (''Waalkil'' "Waal Creek"). The current river shows little signs of these great bends, since the river ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steel Bridges In The Netherlands
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 carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Bridges In The Netherlands
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Bridges Over The Rhine
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The '' Oxford English Dictionary'' traces the origin of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss Bridges
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Nescio
Jan Hendrik Frederik Grönloh (born 22 June 1882 in Amsterdam; died 25 July 1961 in Hilversum), known by his pen name of Nescio (Latin for "I don't know"), was a Dutch writer. Grönloh was a businessman by profession, but as Nescio he is mainly remembered for the three novellas ''De uitvreter'' (The Freeloader), ''Titaantjes'' (Little Titans), and ''Dichtertje'' (Little Poet). His reputation as an important Dutch writer was only established after his death. Biography Nescio was born at Reguliersbreestraat 49 in Amsterdam, the eldest son of Jan Hendrik Frederik Grönloh, blacksmith and shopowner, with whom he shared his full name, and Martha Maria van der Reijden. Nescio grew up as Frits Grönloh, to distinguish him from his father. He was educated at a secular primary school, after which he went to the three-year HBS high school. From 1897 to 1899 he went to the ''Openbare Handelsschool'' (a college level business school). After this he started work as an office clerk in Heng ...

Cycling In The Netherlands
Cycling is a common mode of transport in the Netherlands, with 36% of Dutch people listing the bicycle as their most frequent way of getting around on a typical day, as opposed to the car (45%) and public transport (11%). Cycling has a modal share of 27% of all trips (urban and rural) nationwide. In cities this is even higher, such as Amsterdam which has 38%, and Zwolle 46%. This high frequency of bicycle travel is enabled by excellent cycling infrastructure such as cycle paths, cycle tracks, protected intersections, ample bicycle parking and by making cycling routes shorter and more direct (and therefore usually quicker) than car routes. In the countryside, a growing number of routes connect the Netherlands' villages, towns and cities: some of these paths are part of the Dutch National Cycle Network, a network of routes for bicycle tourism which reaches all corners of the nation. History Cycling became popular in the Netherlands a little later than it did in the United Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kommando Spezialkräfte Marine
Naval Special Forces Command, also called the ("Combat Swimmers", abbreviated "KSM") or (Deployment Group 3402) are an elite special forces unit of the Germany Navy, specializing in commando and amphibious warfare operations. They are the only special-purpose force of the German Navy. The Kampfschwimmer were set up when Germany joined NATO in 1955. During the existence of the GDR (East Germany), the People's Navy (Volksmarine) of the GDR also had a commando frogman force, the Kampfschwimmerkommando 18, which was stationed in Kühlungsborn. They trained at Prora on Rügen. History The first German frogman commando unit was formed under the direction of Alfred von Wurzian during World War II, an Olympic swimmer originally from Austria. Wurzian was initially an artilleryman. He had to overcome a lot of hurdles to form this specialized unit as many brass types could not buy into the concept of such a specialized unit. The unit's name was Küstenjäger-Abteilung "Brandenburg". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
