A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.
The fin whale, also known as the finback whale or common rorqual, is a species of baleen whale and the second-longest cetacean after the blue whale. The biggest individual reportedly measured 26 m (85 ft) in length, with a maximum recorded weight of 77 to 81 tonnes. The fin whale's body is long, slender and brownish-gray in color, with a paler underside to appear less conspicuous from below (countershading).
A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature. In computers, heat sinks are used to cool CPUs, GPUs, and some chipsets and RAM modules. Heat sinks are used with other high-power semiconductor devices such as power transistors and optoelectronics such as lasers and light-emitting diodes (LEDs), where the heat dissipation ability of the component itself is insufficient to moderate its temperature.
Pilot whales are cetaceans belonging to the genus Globicephala. The two extant species are the long-finned pilot whale and the short-finned pilot whale. The two are not readily distinguishable at sea, and analysis of the skulls is the best way to distinguish between the species. Between the two species, they range nearly worldwide, with long-finned pilot whales living in colder waters and short-finned pilot whales living in tropical and subtropical waters. Pilot whales are among the largest of the oceanic dolphins, exceeded in size only by the orca. They and other large members of the dolphin family are also known as blackfish.
The empennage, also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow. The term derives from the French language verb empenner which means "to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces.
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw. It is part of the aircraft empennage, specifically of its stabilizers.
The facility ID number, also called a FIN or facility identifier, is a unique integer number of one to six digits, assigned by the U.S. Federal Communications Commission (FCC) Media Bureau to each broadcast station in the FCC Consolidated Database System (CDBS) and Licensing and Management System (LMS) databases, among others.
Dynamic apnea is a discipline of competitive freediving, also known as competitive apnea. Dynamic apnea covers two of the eight competitive freediving categories recognised by the AIDA International : dynamic with fins (DYN) and dynamic without fins (DNF). Both disciplines require breath held dives where the diver travels in a horizontal position under water under their own power without aid/physical contact of a static surface, with the exception of the pool wall when done indoors. The records can only be recognized in pools of 25m or greater.
Fins is a commune in the Somme department in Hauts-de-France in northern France.
Elpistostegalia is a clade containing Panderichthys and all more derived tetrapodomorph taxa. The earliest elpistostegalians, combining fishlike and tetrapod-like characters, such as Tiktaalik, are sometimes called fishapods. Although historically Elpistostegalia was considered an order of prehistoric lobe-finned fishes, it was cladistically redefined to include tetrapods.
Walter Steyn is an Australian competitive freediver, freediving judge and freediving instructor. He has set 33 Australian national freediving records and currently holds six.
Elisabeth Kristoffersen is a Norwegian freediver and the current president of AIDA Norway. She won the silver medal in the AIDA World Championships 2007 in Maribor, with a dynamic dive to 174 meters.
Stéphane Mifsud is a French free diver born 13 August 1971 in Istres (Bouches-du-Rhône). He is five times world champion in static apnea. His lung capacity was measured at 10.5 litres.
Olivia K. (Liv) Philip is a record breaking freediver and AIDA International instructor who represents Great Britain. In January 2011 she was awarded AIDA's Absolute Freediver Award 2010 for the highest combined score in six freediving disciplines: static apnea, dynamic apnea with fins, dynamic apnea without fins, constant weight with fins, constant weight without fins, and free immersion. In March 2011 she broke the UK women's dynamic, no fins record at the Great Northern Dive Competition, with a 111m swim.
René Cavalero was a French swimmer who won a silver medal in the 4 × 200 m freestyle relay at the 1938 European Aquatics Championships. He finished fourth in the same event at the 1936 Summer Olympics.
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles.
