Countercurrent Pool
A swimming machine, or resistance swimming apparatus ,is a self-contained, pump-driven machine, that enables an athlete or recreational user to swim in place. A swimming machine is possible by accelerating the water past the swimmer or by supporting the swimmer, either in water or on dry land. One type of swimming machine, known as a ''countercurrent swimming machine,'' consists of a water tank at least twice as long and about one and a half times as wide as an average person with the limbs extended. The swimmer swims unrestrained against an adjustable stream of water using jets, propellers, or paddle wheels. Counter current swimming machines made their appearance in the 1970s, initially in the form of pump-driven jetted streams, but received criticism since they created turbulence and an unnatural swimming environment. They were followed up in the 1980s by a propeller- and paddle-wheel-driven machines. These provided a smoother stream of water, thus a more natural swimming exper ...

Countercurrent Exchange
Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other. The flowing bodies can be liquids, gases, or even solid powders, or any combination of those. For example, in a distillation column, the vapors bubble up through the downward flowing liquid while exchanging both heat and mass. The maximum amount of heat or mass transfer that can be obtained is higher with countercurrent than co-current (parallel) exchange because countercurrent maintains a slowly declining difference or gradient (usually temperature or concentration difference). In cocurrent exchange the initial gradient is higher but falls off quickly, leading to wasted potential. For example, in the adjacent diagram, the fluid being heated (exiting top) has a higher exiting temperature than the cooled fluid (exiting bottom) that ...

Countercurrent Chromatography
Countercurrent chromatography (CCC, also counter-current chromatography) is a form of liquid–liquid chromatography that uses a liquid stationary phase that is held in place by inertia of the molecules composing the stationary phase accelerating toward the center of a centrifuge due to centripetal force and is used to separate, identify, and quantify the chemical components of a mixture. In its broadest sense, countercurrent chromatography encompasses a collection of related liquid chromatography techniques that employ two immiscible liquid phases without a solid support. The two liquid phases come in contact with each other as at least one phase is pumped through a column, a hollow tube or a series of chambers connected with channels, which contains both phases. The resulting dynamic mixing and settling action allows the components to be separated by their respective solubilities in the two phases. A wide variety of two-phase solvent systems consisting of at least two immiscible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equatorial Counter Current
The Equatorial Counter Current is an eastward flowing, wind-driven current which extends to depths of in the Atlantic, Indian, and Pacific Oceans. More often called the North Equatorial Countercurrent (NECC), this current flows west-to-east at about 3-10°N in the Atlantic, Indian Ocean and Pacific basins, between the North Equatorial Current (NEC) and the South Equatorial Current (SEC). The NECC is not to be confused with the Equatorial Undercurrent (EUC) that flows eastward along the equator at depths around in the western Pacific rising to in the eastern Pacific. In the Indian Ocean, circulation is dominated by the impact of the reversing Asian monsoon winds. As such, the current tends to reverse hemispheres seasonally in that basin. The NECC has a pronounced seasonal cycle in the Atlantic and Pacific, reaching maximum strength in late boreal summer and fall and minimum strength in late boreal winter and spring. Furthermore, the NECC in the Atlantic disappears ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counter-Currents
Gregory Johnson (born 1971) is an American white nationalist and advocate for a white ethnostate. He is known for his role as editor-in-chief of the white nationalist imprint Counter-Currents Publishing, which he founded in 2010 with Michael Polignano. Through Counter-Currents he has published over 40 books, several of which he wrote himself, either under his real name or the pseudonym Trevor Lynch. He has also written for the anti-Semitic far-right online publication ''Occidental Observer''. A high-profile white nationalist, he has appeared at far-right events in Europe, and in 2019 was arrested in Norway before one such event and deported. He lives in Seattle, Washington. Early life and education Johnson has kept his personal life private, and few photos of him have been published. He was born in 1971, the son of a Democratic union member, he has said in interviews. He has said he was libertarian in high school, read Ayn Rand in early college (becoming in his words "a bit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Countercurrent (PRC Faction, Italy)
Countercurrent ( it, Controcorrente) is a small Italian Trotskyist political group. It used to be a faction within the Communist Refoundation Party. The group emerged in 2006 as a split from Communist Project, when their leader Marco Ferrando decided to leave the party in order to form his own Workers' Communist Party. For the 24–27 July 2008 congress the faction formed a common list with The Ernesto, another minority faction, and obtained 7.7% of the delegates. In that occasion they supported the election of Paolo Ferrero, leader of the Refoundation in Movement-Being Communists motion, as party secretary, thus joining for the first time the majority of the party. In 2010 the faction embraced the Committee for a Workers' International. In 2013, the party was the most important promoter of the massive Genoa Public Transportation Strike that went on for a week and was considered the biggest non-general strike of the year. In 2017, Controcorrente left the CWI over disagreemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The People Of Freedom
The People of Freedom ( it, Il Popolo della Libertà, PdL) was a centre-right political party in Italy. The PdL, launched by Silvio Berlusconi on 18 November 2007, was initially a federation of political parties, notably including Forza Italia and National Alliance, which participated as a joint election list in the 2008 general election. The federation was later transformed into a party during a party congress on 27–29 March 2009. The party's leading members included Angelino Alfano (national secretary), Renato Schifani, Renato Brunetta, Roberto Formigoni, Maurizio Sacconi, Maurizio Gasparri, Mariastella Gelmini, Antonio Martino, Giancarlo Galan, Maurizio Lupi, Gaetano Quagliariello, Daniela Santanchè, Sandro Bondi, and Raffaele Fitto. The PdL formed Italy's government from 2008 to 2011 in coalition with Lega Nord. After having supported Mario Monti's technocratic government in 2011–2012, the party was part of Enrico Letta's government with the Democratic Party, C ...

Counter Currency
A currency pair is the dyadic quotation of the relative value of a currency unit against the unit of another currency in the foreign exchange market. The currency that is used as the reference is called the counter currency, quote currency, or currency and the currency that is quoted in relation is called the base currency or transaction currency. Currency pairs are generally written by concatenating the ISO currency codes (ISO 4217) of the base currency and the counter currency, and then separating the two codes with a slash. Alternatively the slash may be omitted, or replaced by either a dot or a dash. A widely traded currency pair is the relation of the euro against the US dollar, designated as EUR/ USD. The quotation ''EUR/USD 1.2500'' means that one euro is exchanged for 1.2500 US dollars. Here, EUR is the base currency and USD is the quote currency (counter currency). This means that 1 Euro can be exchangeable to 1.25 US Dollars. The most traded currency pairs in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
