Joint Venture
A joint venture (JV) is a business entity created by two or more parties, generally characterized by shared ownership, shared returns and risks, and shared governance. Companies typically pursue joint ventures for one of four reasons: to access a new market, particularly Emerging market; to gain scale efficiencies by combining assets and operations; to share risk for major investments or projects; or to access skills and capabilities. According to Gerard Baynham of Water Street Partners, there has been much negative press about joint ventures, but objective data indicate that they may actually outperform wholly owned and controlled affiliates. He writes, "A different narrative emerged from our recent analysis of U.S. Department of Commerce (DOC) data, collected from more than 20,000 entities. According to the DOC data, foreign joint ventures of U.S. companies realized a 5.5 percent average return on assets (ROA), while those companies’ wholly owned and controlled affiliates ( ...

Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...

Vernon, Eure
Vernon (; nrf, Vernoun) is a commune in the French department of Eure, administrative region of Normandy, northern France. It lies on the banks of the river Seine, about midway between Paris and Rouen. Vernon–Giverny station has rail connections to Rouen and Paris. The town is known for its production of engines by the SNECMA group. History Mentioned in a Latin written document as ''Vernum'', the /m/ at the end could be the last remains of the Celtic ''magus'' 'plain' or 'market', or it is a simple latinization, and the origin is just the Celtic word ''*uerno'', alder tree (Breton ''gwern'', Welsh ''gwern'', Irish ''fern'', modern French ''verne''). The village gave its name to a family who took part in the Norman Conquest of England, and then became a British first name. The village is home to Établissement Saint-Adjutor, a notable private school. Important dates * 750 – First mention of name Vernon by Pepin the Short. * 1070 – Birth of Saint Adjutor. * 1123 – ...

Submarine-launched Ballistic Missile
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles. Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles (ICBMs), with ranges of over , and in many cases SLBMs and ICBMs may be part of the same family of weapons. History Origins The first practical design of a submarine-based launch platform was developed by the Germans near the end of World War II involving a launch tube which contained a V-2 ballistic missile variant and was towed behind a submarine, known by the code-name ''Prüfstand XII''. The war ended before it could be tested, but the engineers who had worked o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermonuclear Weapon
A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make possible the use of non-fissile depleted uranium as the weapon's main fuel, thus allowing more efficient use of scarce fissile material such as uranium-235 () or plutonium-239 (). The first full-scale thermonuclear test was carried out by the United States in 1952; the concept has since been employed by most of the world's nuclear powers in the design of their weapons. Modern fusion weapons consist essentially of two main components: a nuclear fission primary stage (fueled by or ) and a separate nuclear fusion secondary stage containing thermonuclear fuel: the heavy hydrogen isotopes deuterium and tritium, or in modern weapons lithium deuteride ...

M51 (missile)
The M51 SLBM is a French submarine-launched ballistic missile, built by ArianeGroup, and deployed with the French Navy. Designed to replace the M45 (missile), M45 SLBM (In French terminology the MSBS – ''Mer-Sol-Balistique-Stratégique'' "Sea-ground-Strategic ballistic"), it was first deployed in 2010. Each missile carries six to ten Multiple independently targetable reentry vehicle, independently targetable TN 75 thermonuclear warheads. The three-stage engine of the M51 is directly derived from the solid propellant boosters of Ariane 5. Like other blunt-nosed SLBM examples, such as the Trident D5, the M51 uses an drag-reducing aerospike, extensible aerospike in the nose. The missiles are a compromise over the M5 SLBM design, which was to have a range of and carry ten new-generation tête nucléaire océanique' ("oceanic nuclear warhead") MIRVs. Design work on the M5 started in the late 1980s by Aérospatiale, before the programme was renamed the M51 in 1996, when development ...

Kilogram
The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'. The kilogram is defined in terms of the second and the metre, both of which are based on fundamental physical constants. This allows a properly equipped metrology laboratory to calibrate a mass measurement instrument such as a Kibble balance as the primary standard to determine an exact kilogram mass. The kilogram was originally defined in 1795 as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum ''Kilogramme des Archives'' replaced it as the standard of mass. In 1889, a cylinder of platinum-iridium, the International Prototype of the Kilogram (IPK), became the standard of the unit of mass for ...
