Spar (sailing)
A spar is a pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include yards, booms, and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole. In larger vessels during the age of sail, spare spars could be roped together to provide a temporary surface known as a "spar deck". These served as jury-rigged repairs for permanent decks, or as an additional platform under which to shelter goods or crew. The term was also informally applied to areas of the forecastle or quarterdeck where spare spars were stored by laying them flat against the existing decking. In the modern era the term has been used to describe the uppermost deck on flush deck Flush deck is a term in naval architecture. It can refer to any deck of a ship which is continuous from stem to stern. History The flush deck design originated with rice ships built ...

Society Of Professional Audio Recording Services
The Society of Professional Audio Recording Services (SPARS) is an organization that holds conferences and publishes papers about the professional audio community. Its members include many of the top audio engineers working in the industry today. SPARS was founded in 1979 as the Society of Professional Audio Recording Studios by the heads of eleven leading U.S. recording facilities. Among the co-founders were Mack Emerman of Criteria Studios, Chris Stone of Record Plant Studios, Joe Tarsia of Sigma Sound Studios, Howard Schwartz and Bob Liftin of Regent Sound, and Murray Allen of Universal Recording Corporation. SPARS developed the SPARS Code, which was common on the back of CD covers from the late eighties to the mid nineties. It specified whether analogue or digital Digital usually refers to something using discrete digits, often binary digits.

Spar (short Story)
"Spar" is a science fiction short story by American writer Kij Johnson, first published in ''Clarkesworld Magazine''. It won the 2009 Nebula Award for Best Short Story, and was a finalist for the 2010 Hugo Award for Best Short Story. Plot summary A survivor of a space shipwreck is trapped in a raft with an alien, and is pitted against it in a sexual competition for survival and dominance. The story is written in a third-person perspective with a nameless female survivor of a spaceship wreck. A tentacled alien has made it into the escape pod with her and tries to assert its dominance. The female spacer tries to make sense of what the alien is using her for, and what she is to it. She also tries to make a connection to the alien by teaching it about her body parts and how to pleasure her, rather than to assault her. All the while, the spacer has flashbacks to a man, Gary, lost in the accident, who tried to make an emotional connection to her when all she wanted was a physical conne ...

Spar (tree)
A spar tree is the tree used as the highest anchor point in a high lead cable logging setup. The spar tree is selected based on height, location and especially strength and lack of rot in order to withstand the weight and pressure required. Once a spar tree is selected, a climber would remove the tree's limbs and top the tree (a logging term for cutting off the top of the tree). Block and tackle is then affixed to the tree and cabling is run. A "high climber" is the member of the logging crew who scales the tree, limbs it, and tops it. Selecting a tree as a spar is a particularly important task, so the strength and importance of the spar came to hold symbolic meaning for early loggers of the West. The use of spar trees in logging is now rare, having been replaced since the 1970s by portable towers, called yarders A yarder is piece of logging equipment that uses a system of cables to pull or fly logs from the stump to a collection point. It generally consists of an engine, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spar (platform)
A spar is a marine structure, used for floating oil/gas platforms. Named after navigation channel Spar buoys, spar platforms were developed as an extreme deepwater alternative to conventional platforms. The deep draft design of spars makes them less affected by wind, wave, and currents and allows for both dry tree and subsea production. A spar platform consists of a large-diameter, vertical buoyant cylinder(s) supporting a deck. Spars are permanently anchored to the seabed by way of a spread mooring system composed of either a chain-wire-chain or chain-polyester-chain configuration. The cylinder comprises a number of tanks, the lowest contains ballast, mid-water and/or extracted oil, the upper, air for buoyancy. Helical strakes are fitted to the larger & more recent designs to mitigate the effects of vortex-induced motion. There are three primary types of spars; classic, truss, and cell. A classic spar consists of a tall-height, cylindrical hull, with tanks for heavy ballast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spar (mineralogy)
Spar is an old mining or mineralogy term used to refer to crystals that have readily discernible faces. A spar will easily break or cleave into rhomboidal, cubical, or laminated fragments with smooth shiny surfaces. The various spar minerals were a historical term among miners and alchemists for any nonmetallic mineral akin to gypsum, known in Old English as spærstān, ''spear stone'', referring to its crystalline projections. Thus, the word spar in mineralogy has the same root as "spear,". Amongst miners the term "spar" today is frequently used alone to express any bright crystalline substance. Most frequently, spar describes easily cleaved, lightly colored nonmetallic minerals such as feldspar, calcite or baryte. Baryte ( Ba S O4), the main source of barium, is also called "heavy spar" (Greek "barys" means "heavy"). Calcite often forms the dogtooth spar crystals found in vugs and caves. Formation underwater Generally, a spar will form underwater, either in a phreatic zone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Program Of Assisted Reproduction
The Special Program of Assisted Reproduction (SPAR) is a program offered to HIV discordant couples (serodiscordant) at the Bedford Research Foundation's clinical laboratory. The program takes advantage of ART ( assisted reproduction technology) procedures (including "sperm washing") to assist couples achieve a pregnancy who would otherwise risk transmitting the father's HIV infection to the mother and the child through intercourse. SPAR employs extremely stringent safety standards; samples will only be submitted for "sperm washing" and cryopreservation that have first been screened for HIV virus particles and infected cells by specialized molecular biology tests. Only samples that have been determined to have an undetectable HIV viral burden will be submitted for infertility procedures. Assisted reproductive technologies (ART), such as in vitro fertilization (IVF), treat many disorders of the female, but until recent years, treatment options for male factor infertility were limit ...

SPARS
The United States Coast Guard (USCG) Women's Reserve, also known as the SPARS (SPARS was the acronym for "Semper Paratus—Always Ready"), was the women's branch of the United States Coast Guard Reserve. It was established by the United States Congress and signed into law by President Franklin D. Roosevelt on 23 November 1942. This law authorized the acceptance of women into the reserve as commissioned officers and at the enlisted level for the duration of World War II plus six months. Its purpose was to release officers and men for sea duty and to replace them with women at shore stations. Dorothy C. Stratton was appointed director of the SPARS with the rank of lieutenant commander and later promoted to captain. The qualifying age for officer candidates was between 20 and 50, and they were required to have a college degree, or two years of college and two years of professional or business experience. For enlisted personnel, the qualifying age was between 20 and 36, and they w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spar (aeronautics)
In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings while on the ground. Other structural and forming members such as ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all. Where a single spar carries most of the force, it is known as the main spar. Spars are also used in other aircraft aerofoil surfaces such as the tailplane and fin and serve a similar function, although the loads transmitted may be different from those of a wing spar. Spar loads The wing spar provides the majority of the weight support and dynamic load integrity of cantilever monoplanes, often coupled with the strength of the wing 'D' box itself. Together, these two structural components collectively provide the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
