List Of Sovereign States
The following is a list providing an overview of sovereign states around the world with information on their status and recognition of their sovereignty. The 206 listed states can be divided into three categories based on membership within the United Nations System: 193 UN member states, 2 UN General Assembly non-member observer states, and 11 other states. The ''sovereignty dispute'' column indicates states having undisputed sovereignty (188 states, of which there are 187 UN member states and 1 UN General Assembly non-member observer state), states having disputed sovereignty (16 states, of which there are 6 UN member states, 1 UN General Assembly non-member observer state, and 9 de facto states), and states having a special political status (2 states, both in free association with New Zealand). Compiling a list such as this can be a complicated and controversial process, as there is no definition that is binding on all the members of the community of nations concerni ...

Bedroom Community
A commuter town is a populated area that is primarily residential rather than commercial or industrial. Routine travel from home to work and back is called commuting, which is where the term comes from. A commuter town may be called by many other terms: "bedroom community" (Canada and northeastern US), "bedroom town", "bedroom suburb" (US), "dormitory town", or "dormitory suburb" (Britain/ Commonwealth/Ireland). In Japan, a commuter town may be referred to by the ''wasei-eigo'' coinage . The term "exurb" was used from the 1950s, but since 2006, is generally used for areas beyond suburbs and specifically less densely built than the suburbs to which the exurbs' residents commute. Causes Often commuter towns form when workers in a region cannot afford to live where they work and must seek residency in another town with a lower cost of living. The late 20th century, the dot-com bubble and United States housing bubble drove housing costs in Californian metropolitan areas to hist ...

Wye (railroad)
In railroad structures, and rail terminology, a wye (like the'' 'Y' ''glyph) or triangular junction (often shortened to just "triangle") is a triangular joining arrangement of three rail lines with a railroad switch (set of points) at each corner connecting to each incoming line. A turning wye is a specific case. Where two rail lines join, or in a joint between a railroad's mainline and a spur, wyes can be used at a mainline rail junction to allow incoming trains the ability to travel in either direction, or in order to allow trains to pass from one line to the other line. Wyes can also be used for turning railway equipment, and generally cover less area than a balloon loop doing the same job, but at the cost of two additional sets of points to construct, then maintain. These turnings are accomplished by performing the railway equivalent of a three-point turn through successive junctions of the wye, the direction of travel and the relative orientation of a locomotive or rai ...

Monongahela Railroad
The Monongahela Railway was a coal-hauling short line railroad in Pennsylvania and West Virginia in the United States. It was jointly controlled originally by the Pennsylvania Railroad, New York Central subsidiary Pittsburgh and Lake Erie Railroad, and the Baltimore and Ohio Railroad, with NYC and PRR later succeeded by Penn Central Transportation. The company operated its own line until it was merged into Conrail on May 1, 1993. The primary connection to both controlling systems was at Brownsville, Pennsylvania - with the south end of the P&LE's Pittsburgh, McKeesport and Youghiogheny Railroad and with the PRR's ex- Brownsville Railway. The PRR also interchanged traffic at Hoover, Pennsylvania, the end of its Coal Lick Run Branch. The B&O Railroad interchanged at Leckrone, Pennsylvania, and Rivesville, West Virginia. At the end of 1970 it operated 193 miles of road on 281 miles of track; that year it reported 446 million ton-miles of revenue freight. History The ...

Rail Yard
A rail yard, railway yard, railroad yard (US) or simply yard, is a series of tracks in a rail network for storing, sorting, or loading and unloading rail vehicles and locomotives. Yards have many tracks in parallel for keeping rolling stock or unused locomotives stored off the main line, so that they do not obstruct the flow of traffic. Cars or wagons are moved around by specially designed yard switchers (US) or shunters, a type of locomotive. Cars or wagons in a yard may be sorted by numerous categories, including railway company, loaded or unloaded, destination, car type, or whether they need repairs. Yards are normally built where there is a need to store rail vehicles while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations. Many yards are located at strategic points on a main line. Main-line yards are often composed of an up yard and a down yard, linked to the associated direction of travel. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gradient
In vector calculus, the gradient of a scalar-valued differentiable function of several variables is the vector field (or vector-valued function) \nabla f whose value at a point p is the "direction and rate of fastest increase". If the gradient of a function is non-zero at a point , the direction of the gradient is the direction in which the function increases most quickly from , and the magnitude of the gradient is the rate of increase in that direction, the greatest absolute directional derivative. Further, a point where the gradient is the zero vector is known as a stationary point. The gradient thus plays a fundamental role in optimization theory, where it is used to maximize a function by gradient ascent. In coordinate-free terms, the gradient of a function f(\bf) may be defined by: :df=\nabla f \cdot d\bf where ''df'' is the total infinitesimal change in ''f'' for an infinitesimal displacement d\bf, and is seen to be maximal when d\bf is in the direction of the gradi ...

Brownsville, PA
Brownsville is a borough (Pennsylvania), borough in Fayette County, Pennsylvania, United States, first settled in 1785 as the site of a trading post a few years after the Sullivan Expedition, defeat of the Iroquois enabled a post-Revolutionary war resumption of westward migration. The Trading Post soon became a tavern and Inn, and was soon receiving emigrants heading west as it was located above the cut bank overlooking first ford that could be reached to those descending from the Mountains. Brownsville is located south of Pittsburgh along the east bank of the Monongahela River. According to the United States Census Bureau, the borough of Brownsville, located as a county (Pennsylvania), county border town has a total area of , of which is land and , or 10.47%, is water—most of which is the Fayette County, Pennsylvania, Fayette County half of the Monongahela River between the community and the flatter lands of opposite shore West Brownsville, PA, West Brownsville in Washingto ...

Cut Bank
A cut bank, also known as a river cliff or river-cut cliff, is the outside bank of a curve or meander in a water channel (stream), which is continually undergoing erosion.Essentials of Geology, 3rd Ed, Stephen Marshak Cut banks are found in abundance along mature or meandering streams, they are located on the ''outside'' of a stream bend, known as a meander, opposite the slip-off slope on the inside of the bend. They are shaped much like a small cliff, and are formed by the erosion of soil as the stream collides with the river bank. As opposed to a point bar, which is an area of deposition, a cut bank is an area of erosion. Typically, cut banks are steep and may be nearly vertical. Often, particularly during periods of high rainfall and higher-than average water levels, trees and poorly placed buildings can fall into the stream due to mass wasting events. Given enough time, the combination of erosion along cut banks and deposition along point bars can lead to the formation of a ...

Western Pennsylvania
Western Pennsylvania is a region in the U.S. state of Pennsylvania, covering the western third of the state. Pittsburgh is the region's principal city, with a metropolitan area population of about 2.4 million people, and serves as its economic and cultural center. Erie, Altoona, and Johnstown are its other metropolitan centers. As of the 2010 census, Western Pennsylvania's total population is nearly 4 million. Although the Commonwealth does not designate Western Pennsylvania as an official region, since colonial times it has retained a distinct identity not only because of its geographical distance from Philadelphia, the beginning of Pennsylvania settlement, but especially because of its topographical separation from the east by virtue of the Appalachian Mountains, which characterize much of the western region. The strong cultural identity of Western Pennsylvania is reinforced by the state supreme court holding sessions in Pittsburgh, in addition to Harrisburg and Philadelphia ...

Monongahela River
The Monongahela River ( , )—often referred to locally as the Mon ()—is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in North Central West Virginia, north-central West Virginia and Greater Pittsburgh, Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river's entire length is navigable via a series of locks and dams. Etymology The Unami language, Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian Church, Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Lenape language, Indian tongue the name of this river was ''Mechmenawungihilla'' (alter ...

Left Bank
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography, as follows. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking downstream; a well-known example of this being the sections of Paris as defined by the river Seine. The shoreline of ponds, swamps, estuaries, reservoirs, or lakes are also of interest in limnology and are sometimes referred to as banks. The grade ...
