Raft
A raft is any flat structure for support or transportation over water. It is usually of basic design, characterized by the absence of a hull. Rafts are usually kept afloat by using any combination of buoyant materials such as wood, sealed barrels, or inflated air chambers (such as pontoons), and are typically not propelled by an engine. Rafts are an ancient mode of transport; naturally-occurring rafts such as entwined vegetation and pieces of wood have been used to traverse water since the dawn of humanity. Human-made rafts Traditional or primitive rafts were constructed of wood or reeds. Modern rafts may also use pontoons, drums, or extruded polystyrene Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a ... blocks. Inflatable rafts up to the 20th century used flotation chambers ...

Rafting
Rafting and whitewater rafting are recreational outdoor activities which use an inflatable raft to navigate a river or other body of water. This is often done on whitewater or different degrees of rough water. Dealing with risk is often a part of the experience. This activity as an adventure sport has become popular since the 1950s, if not earlier, evolving from individuals paddling to rafts with double-bladed paddles or oars to multi-person rafts propelled by single-bladed paddles and steered by a person at the stern, or by the use of oars. Rafting on certain sections of rivers is considered an extreme sport and can be fatal, while other sections are not so extreme or difficult. Rafting is also a competitive sport practiced around the world which culminates in a world rafting championship event between the participating nations. The International Rafting Federation, often referred to as the IRF, is the worldwide body which oversees all aspects of the sport. Equipme ...

Great Raft
The Great Raft was a gigantic log jam or series of "rafts" that clogged the Red and Atchafalaya rivers and was unique in North America in terms of its scale. Origin The Great Raft probably began forming in the 12th century. It grew from its upper end, while decaying or washing out at the lower end. By the early 1830s, it spanned more than . The raft, at one point, extended for from Loggy Bayou to Carolina Bluffs. Because of its scale, the Great Raft became incorporated in the mythology of the regional Caddo tribe, which had been in the area for thousands of years. They credited it with protecting them from competing tribes, as well as intermittently causing floods on the land and making it fertile for agriculture. Harrelson et al. describe the origins of the raft: This ecosystem of entangled logs, vegetation and sediments remained in place for almost two millennia, altering the flow regime of the Red River and causing a complete change in its geomorphic character from a sin ...

George Raft
George Raft (born George Ranft; September 26, 1901 – November 24, 1980) was an American film actor and dancer identified with portrayals of gangsters in crime melodramas of the 1930s and 1940s. A stylish leading man in dozens of movies, Raft is remembered for his gangster roles in ''Quick Millions (1931 film), Quick Millions'' (1931) with Spencer Tracy, ''Scarface (1932 film), Scarface'' (1932) with Paul Muni, ''Each Dawn I Die'' (1939) with James Cagney, ''Invisible Stripes'' (1939) with Humphrey Bogart, Billy Wilder's comedy ''Some Like It Hot'' (1959) with Marilyn Monroe and Jack Lemmon, and as a dancer in ''Bolero (1934 film), Bolero'' (1934) with Carole Lombard and a truck driver in ''They Drive by Night'' (1940) with Ann Sheridan, Ida Lupino and Bogart. Raft said he never regarded himself as an actor. "I wanted to be me," he said.

Floating Raft System
Floating raft is a land-based building foundation that protects it against settlement and liquefaction of soft soil from seismic activity. It was a necessary innovation in the development of tall buildings in the wet soil of Chicago in the 19th century, when it was developed by John Wellborn Root who came up with the idea of interlacing the concrete slab with steel beams. The earliest precursor to the modern version may be the concrete rafts developed for the building of Millbank Prison in 1815 by Robert Smirke. For a floating raft foundation – or simply "floating foundation" – the foundation has a volume such that, if that volume filled with soil, it would be equal in weight to the total weight of the structure. When the soil is so soft that not even friction piles will support the building load, these types of foundation are the final option and makes the building behave like a boat: obeying Archimedes' principle, buoyed up by the weight of the earth displaced in creating ...

Raft Spider
The raft spider, scientific name ''Dolomedes fimbriatus'', is a large semi-aquatic spider of the family Pisauridae found throughout north-western and central Europe. It is one of only two species of the genus ''Dolomedes'' found in Europe, the other being the slightly larger Great raft spider, ''Dolomedes'' ''plantarius'' which is endangered in the UK. Habitat and description Raft spiders are semiaquatic, semi-aquatic and adults inhabit freshwater wetlands, specifically wet heaths and acid swamps; although juveniles are predominantly found in terrestrial vegetation surrounding wetland areas. Adults are dark brown with a conspicuous white, cream or yellow stripe along both sides of their abdomen and thorax. Juveniles are similar in appearance but often have green translucent legs. As is common in other spiders, female raft spiders (body length: 9–22mm) are usually larger than males (body length (9-15mm). Dolomedes fimbriatus was described in chapter 5 of the book ''Svenska Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipid Raft
The plasma membranes of cells contain combinations of glycosphingolipids, cholesterol and protein receptors organised in glycolipoprotein lipid microdomains termed lipid rafts. Their existence in cellular membranes remains somewhat controversial. It has been proposed that they are specialized membrane microdomains which compartmentalize cellular processes by serving as organising centers for the assembly of signaling molecules, allowing a closer interaction of protein receptors and their effectors to promote kinetically favorable interactions necessary for the signal transduction. Lipid rafts influence membrane fluidity and membrane protein trafficking, thereby regulating neurotransmission and receptor trafficking. Lipid rafts are more ordered and tightly packed than the surrounding bilayer, but float freely within the membrane bilayer. Although more common in the cell membrane, lipid rafts have also been reported in other parts of the cell, such as the Golgi apparatus and lysosome ...

Raft (band)
Raft is a French pop band active in the 1980s, most notable for their 1987 hit single, " Yaka dansé". Biography The band was a duet composed of Christian Fourgeron (guitar, vocals) and Pierre Schott (guitar, bass, vocals, born 24 April 1958). They begin their musical career in 1985 with their single "Io (c'est ça)" which passed unnoticed in France. However, in 1987, they had their first hit with "Yaka dansé (l'arborigène)", which was a number 2 hit in France, and earned a gold disc. The single was succeeded by "Femmes du Congo", which achieved a moderate success in comparison. The band's songs contained many puns and dealt with grave themes of society, sung on joyful music. In 1988, they released their first album entitled ''Madagascar'' and was the opening act for Niagara Niagara may refer to: Geography Niagara Falls and nearby places In both the United States and Canada *Niagara Falls, the famous waterfalls in the Niagara River *Niagara River, part of the U.S.–Can ...

Remote Area Firefighting Team
Remote Area Firefighting Team (RAFT) personnel are specialist members of the New South Wales Rural Fire Service or National Parks and Wildlife Service who are particularly effective for work in rugged, isolated areas that firefighting tankers can’t access by road. They can then be transported in 4WD before hiking to the fireground, or sometimes winched in by helicopter. RAFTs are skilled in dry firefighting techniques such as creating firebreaks by cutting mineral earth trails or undertaking backburning work. The winch training is just one aspect of the RAFT program which also includes a medical examination and fitness test to ensure crews can cope with this strenuous form of firefighting. The ‘arduous pack test’ involves walking 4.83 km carrying 20 kg in 45 minutes or less. Because RAFT operate a long way from vehicle support, RAFT personnel rely on each other, so teams are made up of people with a good mix of training, good navigational skills, and the ability ...
