Rapid Transit
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separation, grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are usually electric railway, electric railways, that unlike buses or trams operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles. Modern services on rapid transit systems are provided on designated lines between metro station, stations typically using electric multiple units on railway tracks. Some systems use rubber-tyred metro, guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typica ...

Military Terminology
Military terminology refers to the terminology, terms and language of military organizations, military personnel, personnel, and military doctrine. Much like other forms of corporate jargon, military terminology is distinguishable from colloquial language by its use of new or repurposed words and phrases typically only understandable by current and former members of the military or associated companies and agencies. Common understanding The operational pressure for uniform understanding has developed since the early 20th century with the importance of Joint warfare, joint operations between different services (army, navy, air force) of the same country. International alliances and operations, including peacekeeping, have added additional complexity. For example, the NATO alliance now maintains a large dictionary of common terms for use by member countries. Development work is also taking place between NATO and Russia on common terminology for extended air defence, in English, Fre ...

Subterranean Warfare
Subterranean warfare or underground warfare is warfare conducted underneath the ground surface. It is predominantly conducted in tunnels and underground cavities, both natural (such as caves) and artificial (such as sewerage and subway systems). Underground military facilities play a key role in many nations, and there are more than 10,000 underground military facilities worldwide. As such, underground warfare is a nearly inevitable component of modern conflicts. Combatants often go underground to counteract overmatch such as that faced when taking on a superpower. Underground environments generally protect from surface attacks and Aerial warfare, aerial attacks such as airstrikes and Barrage (artillery), artillery barrages, and are also generally dark, enclosed, and well-protected, making them difficult for even experienced forces to effectively fight in. History Subterranean warfare was occasionally carried out during World War II. Examples are the defense of the Adzhimushk ...

Manhole Cover
A manhole cover is a removable plate forming the lid over the opening of a manhole, an opening large enough for a person to pass through that is used as an access point for an underground vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorized persons and material. Manhole covers date back at least to the era of ancient Rome, which had sewer grates made from stone. Description Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than . The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorized people without suitable tools to remove them. Manhole covers may also be made from glass-reinforced plastic or other composite material (especially in Europe, or where cover theft is of concern). Because of law restricting acceptable manual handling weights, Europe has seen a move towar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Warfare
Urban warfare is warfare in urban areas such as towns and cities. Urban combat differs from combat in the open at both Military operation, operational and the Military tactics, tactical levels. Complicating factors in urban warfare include the presence of civilians and the complexity of the urban terrain. Urban combat operations may be conducted to capitalize on strategic or tactical advantages associated with the possession or the control of a particular urban area or to deny these advantages to the enemy. It is considered to be arguably the most difficult form of warfare. Fighting in urban areas negates the advantages that one side may have over the other in armor, heavy artillery, or air support. Ambushes laid down by small groups of soldiers with handheld anti-tank weapons can destroy entire columns of modern armor (as in the Battle of Grozny (1994–95), First Battle of Grozny), while artillery and air support can be severely reduced if the "superior" party wants to limit ci ...

Mouse-holing
Mouse-holing is a military tactics, tactic used in urban warfare in which soldiers create access to adjoining rooms or buildings by blasting or tunneling through a wall. The tactic is used to avoid open streets since advancing infantry, caught in enfilade, are easily targeted by machine-gun and sniper fire. Another purpose is to reach enemy troops hidden within a structure. Use Mouse-holing began to appear in military tactical manuals during World War II. The tactic allows combatants to move around an urban battlefield under cover without needing to expose themselves to enemy fire or observation. A typical passage is large enough for a single file of soldiers. Large unrestricted holes can compromise the Structural engineering, structural integrity of the building and offer little cover from opposing forces. During the Battle of Ortona in 1943, the Canadian Army, which gave the tactic its name, used it to great effect, breaching the walls of buildings (houses in Ortona shared adj ...

Sewage
Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. It is typically transported through a sewerage, sewer system. Sewage consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality.

Sewage also contains soaps and detergents. Food waste may be present from dishwashing, and food quantities may be increased where garbage disposal units are used. In regions where toilet paper is used rather than bidets, that paper is also added to the sewage. Sewage contains macro-pollu ...

Airport
An airport is an aerodrome with extended facilities, mostly for commercial Aviation, air transport. They usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a airplane, plane to take off and to land or a helipad, and often includes adjacent utility buildings such as Air traffic control, control towers, hangars and airport terminal, terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and Airport lounge, lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Airport operations are extremely complex, with a complicated system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airpor ...

Urban Area
An urban area is a human settlement with a high population density and an infrastructure of built environment. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlet (place), hamlets; in urban sociology or urban anthropology, it often contrasts with natural environment. The development of earlier predecessors of modern urban areas during the urban revolution of the 4th millennium BCE led to the formation of human civilization and ultimately to modern urban planning, which along with other human activities such as exploitation of natural resources has led to a human impact on the environment. Recent historical growth In 1950, 764 million people (or about 30 percent of the world's 2.5 billion people) lived in urban areas. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Transport
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in railway track, tracks, which usually consist of two parallel steel railway track, rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and rail freight transport, freight transport globally, thanks to its Energy efficiency in transport, energy efficiency and potentially high-speed rail, high speed.Rolling stock on rails generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by Diesel locomotive, diesel or Electric locomotive, electric locomotives. While railway transport is capital intensity, capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhoushan.
