Aquatic Sports
The asterisk ( ), from Late Latin , from Ancient Greek , ''asteriskos'', "little star", is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star. Computer scientists and mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or '' C*-algebra''). In English, an asterisk is usually five- or six-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication. History The asterisk has already been used as a symbol in ice age cave paintings. There is also a two thousand-year-old character used by Aristarchus of Samothrace called the , , which he used when proofreading Homeric poetry to mark lines that were duplicated. Origen ...

List Of Water Sports
Water sports or aquatic sports are sport activities conducted on waterbodies, and can be categorized according to the degree of immersion by the participants. On the water * Boat racing, the use of powerboats to participate in races * Boating, the use of boats for personal recreation * Cable skiing, similar to wake boarding but with cables for artificial maneuvering * Canoe polo combines boating and ball handling skills with a contact team game, where tactics and positional play are as important as the speed and fitness of the individual athletes. * Canoeing is an activity which involves paddling a canoe with a single-bladed paddle. Most present-day canoeing is done as or as a part of a sport or recreational activity. * Dragon boat racing, teams of 20 paddlers racing the ancient dragon boat * Fishing, the recreation and sport of catching fish * Flyboard, a brand of hydroflighting device which supplies propulsion to drive the Flyboard into the air to perform a sport know ...

Aquatic Therapy
Aquatic therapy refers to treatments and exercises performed in water for relaxation, fitness, physical rehabilitation, and other therapeutic benefit. Typically a qualified aquatic therapist gives constant attendance to a person receiving treatment in a heated therapy pool. Aquatic therapy techniques include Ai Chi, Aqua Running, Bad Ragaz Ring Method, Burdenko Method, Halliwick, Watsu, and other aquatic bodywork forms. Therapeutic applications include neurological disorders, spine pain, musculoskeletal pain, postoperative orthopedic rehabilitation, pediatric disabilities, and pressure ulcers. Overview Aquatic therapy refers to water-based treatments or exercises of therapeutic intent, in particular for relaxation, fitness, and physical rehabilitation. Treatments and exercises are performed while floating, partially submerged, or fully submerged in water. Many aquatic therapy procedures require constant attendance by a trained therapist, and are performed in a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Hazard
A hazard is an area of a golf course in the sport of golf which provides a difficult obstacle, which may be of two types: (1) water hazards such as lakes and rivers; and (2) man-made hazards such as bunkers. The governing body for the game of golf outside the US and Canada, The R&A, say that ''A "hazard" is any bunker or water hazard''. Special rules apply to play balls that fall in a hazard. For example, a player may not touch the ground with their club before playing a ball, not even for a practice swing. A ball in any hazard may be played as it lies without penalty. If it cannot be played from the hazard, the ball may be hit from another location, generally with a penalty of one stroke. The Rules of Golf govern exactly from where the ball may be played outside a hazard. Bunkers (or sand traps) are shallow pits filled with sand and generally incorporating a raised lip or barrier, from which the ball is more difficult to play than from grass. Bunker A bunker is a depression n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Plants
Aquatic plants are plants that have adapted to living in aquatic environments ( saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecolog ...

Aquatic (other)
Aquatic means relating to water; living in or near water or taking place in water; does not include groundwater, as "aquatic" implies an environment where plants and animals live. Aquatic(s) may also refer to: * Aquatic animal, either vertebrate or invertebrate, which lives in water for most or all of its life * Aquatic ecosystem, environmental system located in a body of water * Aquatic plants, also called hydrophytic plants or hydrophytes, are plants that have adapted to living in or on aquatic environments * ''Aquatic'' (album), 1994 album by the Australian experimental jazz trio, The Necks * Aquatics, another name for water sports See also * * Aquatics (other) * Freshwater ecosystem, an earth aquatic ecosystems * Limnology Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems.
