Unincorporated Community
An unincorporated area is a region that is not governed by a local municipal corporation. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world either have no unincorporated areas at all or these are very rare: typically remote, outlying, sparsely populated or uninhabited areas. By country Argentina In Argentina, the provinces of Chubut, Córdoba, Entre Ríos, Formosa, Neuquén, Río Negro, San Luis, Santa Cruz, Santiago del Estero, Tierra del Fuego, and Tucumán have areas that are outside any municipality or commune. Australia Unlike many other countries, Australia has only one level of local government immediately beneath state and territorial governments. A local government area (LGA) often contains several towns and even entire metropolitan areas. Thus, aside from very sparsely populated areas and a few other special cases, almost all of Australia is part of an LGA. Uninc ...

United States Bureau Of Mines
For most of the 20th century, the United States Bureau of Mines (USBM) was the primary United States government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources. The Bureau was abolished in 1996. Summary USBM was established in the Department of the Interior on May 16, 1910, pursuant to the Organic Act (Public Law 179), to deal with a wave of catastrophic mine disasters. The Bureau's mission was gradually expanded to include: * The conduct of research to enhance the safety, health, and environmental impact of mining and processing of minerals and materials. * The collection, analysis, and dissemination of information about mining and processing of more than 100 mineral commodities across the Nation and in more than 185 countries around the world. * Analysis of the impact of proposed mineral-related laws and regulations upon the national interest. * Production, conservation, sale, and di ...

Bruceton Analysis
A Bruceton analysis is one way of analyzing the sensitivity of explosives as described originally by Dixon and Mood in 1948. Also known as the " Up and Down Test" or "the staircase method", a Bruceton analysis relies upon two parameters: first stimulus and step size. A stimulus is provided to the sample, and the results noted. If a positive result is noted, then the stimulus is decremented by the step size. If a negative result occurs, the stimulus is increased. The test continues with each sample tested at a stimulus 1 step up or down from the previous stimulus if the previous result was negative or positive. The results are tabulated and analyzed via Bruceton analysis, a simple computation of sums that can be performed by pencil and paper, to provide estimates of the mean and standard deviation. Confidence estimates are also produced. Other analysis methods are the Neyer d-optimal test and Dror and Steinberg 008sequential procedure. Bruceton analysis has an advantage over the mo ...

National Defense Research Committee
The National Defense Research Committee (NDRC) was an organization created "to coordinate, supervise, and conduct scientific research on the problems underlying the development, production, and use of mechanisms and devices of warfare" in the United States from June 27, 1940, until June 28, 1941. Most of its work was done with the strictest secrecy, and it began research of what would become some of the most important technology during World War II, including radar and the atomic bomb. It was superseded by the Office of Scientific Research and Development in 1941, and reduced to merely an advisory organization until it was eventually terminated during 1947. Organization The NDRC was created by an order of President Franklin Delano Roosevelt on June 27, 1940. It was part of the Council of National Defense, which had been created during 1916 to coordinate industry and resources for national security purposes. Vannevar Bush, the director of the Carnegie Institution, had pressed for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manhattan Project
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of th ...

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Maryland, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pittsburgh And West Virginia Railway
The Pittsburgh and West Virginia Railway was a railroad in the Pittsburgh, Pennsylvania and Wheeling, West Virginia, areas. Originally built as the Wabash Pittsburgh Terminal Railway, a Pittsburgh extension of George J. Gould's Wabash Railroad, the venture entered receivership in 1908 and the line was cut loose. An extension completed in 1931 connected it to the Western Maryland Railway at Connellsville, Pennsylvania, forming part of the Alphabet Route, a coalition of independent lines between the Northeastern United States and the Midwest. It was leased by the Norfolk and Western Railway in 1964 in conjunction with the N&W acquiring several other sections of the former Alphabet Route, but was leased to the new spinoff Wheeling and Lake Erie Railway in 1990, just months before the N&W was merged into the Norfolk Southern Railway. The original Wabash Pittsburgh Terminal Railway built several massive engineering works, including the Wabash Terminal in downtown Pittsburgh, damage ...
