Fanboat
An airboat (also known as a planeboat, swamp boat, bayou boat, or fanboat) is a flat-bottomed watercraft propelled by an aircraft-type propeller and powered by either an aircraft or automotive engine. It is commonly used for fishing, hunting, recreation, and ecotourism. Airboats are a common means of transportation in marshy and/or shallow areas where a standard inboard or outboard engine with a submerged propeller would be impractical, most notably in the Florida Everglades but also in the Kissimmee and St. Johns rivers, and the Mekong River and Delta, as well as the Louisiana bayous and Mesopotamian Marshes. Overview The airboat’s characteristic flat-bottom allows for easy navigation through marshes and other shallow bodies of water, including flooded areas. A version is also adapted for use on ice. The lack of operating parts below the waterline makes the craft ideal for rescue operations. The airboat is propelled by a column of air generated by a propeller, with win ...

Iraqi Dinar
The Iraqi dinar (ISO 4217, code: IQD; ), ) is the currency of Iraq. The Iraqi dinar is issued by the Central Bank of Iraq (CBI). On 7 February 2023, the exchange rate with the US dollar was US$1 = 1300 dinars. History The Iraqi dinar entered circulation on 1 April 1932, replacing the Indian rupee, which had been the official currency since the Mesopotamian campaign, British occupation of the country in World War I, at a rate of 1 dinar = 11 rupees. The dinar was pegged at par with Pound sterling, sterling until 1959 when, without changing its value, the peg was switched to the United States dollar at the rate of IQD 1 = US$2.80. By not following the US devaluations in 1971 and 1973, the official rate rose to US$3.3778, before a 5% devaluation reduced its rate to US$3.2169, a rate which remained until the Gulf War in 1990, although in late 1989 the black market rate was reported at five to six times higher than the official rate. Post-1990 developments After the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alexander Graham Bell
Alexander Graham Bell (; born Alexander Bell; March 3, 1847 – August 2, 1922) was a Scottish-born Canadian Americans, Canadian-American inventor, scientist, and engineer who is credited with patenting the first practical telephone. He also co-founded the AT&T Corporation, American Telephone and Telegraph Company (AT&T) in 1885. Alexander Melville Bell, Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices, which eventually culminated in his being awarded the first United States patent law, U.S. patent for the telephone, on March 7, 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Many other inventions marked Bell's later life, including ground-breaking work in Free-space optical commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mud Season
Mud season (US English) or breakup (Canadian English) is a period in late winter and early spring when travel over ice is no longer safe and travel overland is more difficult as frozen earth thaws and soil becomes muddy from Meltwater, melting snow. Description Mud season occurs in places where the ground freezes in winter and thaws in spring. Dirt roads and paths become muddy because the deeply frozen ground thaws from the surface down as the air temperature warms above melting point, freezing. The frozen lower layers of ground prevent water from percolating into the soil so the surface layers of soil become saturated with water. Clay-based soil, especially when combined with poor drainage, is especially prone to forming deep and sticky mud. In sandy soils, the top unfrozen layer becomes waterlogged during thaws, but does not form viscous mud. On the Great Plains, a particular type of clay (Bentonite, bentonite clay, or aluminum phyllosilicate) turns into a sticky form of soil ...

Rasputitsa
''Rasputitsa'' (from ; literally "season of bad roads") is the mud season that occurs in various rural areas of Eastern Europe, when the rapid snowmelt or thawing of frozen ground combined with wet weather in spring, or heavy rains in autumn lead to muddy conditions that make travel on unpaved roads problematic and even treacherous. Rasputitsa has repeatedly affected wars by causing military vehicles and artillery pieces to become mired in the mud. In conjunction with the Russian Winter, general conditions of winter, rasputitsa has been credited with encumbering the military campaigns of First French Empire, Napoleonic France in 1812 and Nazi Germany during Operation Barbarossa, as well as all belligerents in the Russian invasion of Ukraine, 2022 Russian invasion of Ukraine. In countries of the former Soviet Union, the concept is applied to two periods during the year – spring and autumn – and also refers to impassable road conditions during such a period, specifically the h ...

Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Ground Effect Vehicle
A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIGE or WIG), ground-effect craft/machine (GEM), wingship, flarecraft, surface effect vehicle or ekranoplan (), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water. Typically, it is designed to glide over a level surface (usually over the sea) by making use of ground effect (aerodynamics), ground effect, the aerodynamic interaction between the moving wing and the surface below. Some models can operate over any flat area such as frozen lakes or flat plains similar to a hovercraft. The term Ground-Effect Vehicle originally referred to any craft utilizing ground effect, including what is known later as hovercraft, in descriptions of patents during the 1950s. However, this term is nowadays regarded as distinct from air-cushion vehicles or hovercraft. The definition of GEVs does not include racecars utilizing Ground effect (cars) ...

Aerosled
An Aerosledge (, "aerosani") is a propeller-driven sledge, sleigh or toboggan which slides on runners or skis. Aerosleds are used for communications, mail deliveries, medical aid, emergency recovery, and patrolling borders in countries such as northern Russia, as well as for recreation. Aerosani were used by the Soviet Red Army during the Winter War and World War II. The first aerosledges may have been built in 1903–05 by Sergei Nezhdanovsky. In 1909–10, young Igor Sikorsky designed and tested an aerosledge, before going on to build multi-engine airplanes and helicopters. They were light plywood vehicles on skis, powered by used vintage aircraft engines and propellers. Military usage Military use of the aerosani goes back to at least the 1910s. During World War I, aerosani were used for reconnaissance, communicating, and light raiding in northern areas. During the 1939–40 Winter War against Finland some were equipped with a machine gun ring mount on the roof. They could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
