Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''.

Gilo Cardozo
Gilo ( he, גִּלֹה) is an Israeli settlement in south-western East Jerusalem, with a population of 30,000, mostly Jewish inhabitants. Although it is located within the Jerusalem Municipality, it is widely considered a settlement, because as one of the five Ring Neighborhoods built by Israel surrounding Jerusalem, it was built on land in the West Bank that was occupied by and effectively annexed to Israel following the 1967 Six-Day War and 1980 Jerusalem Law. The international community regards Israeli settlements illegal under international law, although Israel disputes this. Israel also disputes its designation as a settlement, and it is administered as part of the Jerusalem municipality. Geography Gilo is located on a hilltop in southwestern East Jerusalem separated from Beit Jala by a deep gorge. The Tunnels Highway to Gush Etzion runs underneath it on the east, and the settlement of Har Gilo is visible on the adjacent peak. Beit Safafa and Sharafat are located ...

Manufacturing Companies Established In 2008
Manufacturing is the creation or Production (economics), production of goods with the help of equipment, Work (human activity), labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of Human behavior, human activity, from handicraft to High tech manufacturing, high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector of the economy, primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, Major appliance, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).

Aircraft Engine Manufacturers Of The United Kingdom
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air bal ...

Mount Everest
Mount Everest (; Tibetan: ''Chomolungma'' ; ) is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The China–Nepal border runs across its summit point. Its elevation (snow height) of was most recently established in 2020 by the Chinese and Nepali authorities. Mount Everest attracts many climbers, including highly experienced mountaineers. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the "standard route") and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, and wind, as well as hazards from avalanches and the Khumbu Icefall. , over 300 people have died on Everest, many of whose bodies remain on the mountain. The first recorded efforts to reach Everest's summit were made by British mountaineers. As Nepal did not allow fore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paramotor
Paramotor is the generic name for the harness and propulsive portion of a powered paraglider ("PPG"). There are two basic types of paramotors: foot launch and wheel launch. Foot launch models consist of a frame with harness, fuel tank, engine, and propeller. A hoop with protective netting primarily keeps lines out of the propeller. The unit is worn like a large backpack to which a Paraglider is attached through carabiners. Wheel launch units either come as complete units with their own motor and propeller, or as an add-on to a foot-launch paramotor. They usually have 3 (trike) or 4 (quad) wheels, with seats for one or two occupants. These are distinct from powered parachutes which are generally much heavier, more powerful, and have different steering. The term was first used by Englishman Mike Byrne in 1980 and popularized in France around 1986 when La Mouette began adapting power to the then-new paraglider wings. Power plants are almost exclusively small two-stroke internal c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most ...

Semley
Semley is a village in Sedgehill and Semley civil parish in Wiltshire, England, about north-east of Shaftesbury in neighbouring Dorset. The hamlet of Sem Hill lies about a quarter of a mile west of the village. The River Sem, from which the village takes its name, forms part of the northern boundary of the parish. History In AD 955 King Eadwig granted land to Wilton Abbey, and Semley was probably part of that estate. In the 1530s. under Henry VIII's Dissolution of the Monasteries, the Abbey had to surrender its lands to the Crown, including the manor of Semley. In 1541 Henry VIII granted Semley to Sir Edward Bayntun and his wife Lady Isabel as part of his policy of re-allocated monastic land to his nobles. In 1572 in Queen Elizabeth's reign, Bayntun's son Francis restored Semley to the Crown, and later that year Elizabeth I granted Semley to Matthew Arundell of Wardour Castle, who was knighted in 1574. In 1605 his son Thomas was created Baron Arundell of Wardour, and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44. Larger light aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Aerial Vehicles
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE T ...
