SK Channel
SK channels (small conductance calcium-activated potassium channels) are a subfamily of calcium-activated potassium channels. They are so called because of their small single channel conductance in the order of 10 pS. SK channels are a type of ion channel allowing potassium cations to cross the cell membrane and are activated (opened) by an increase in the concentration of intracellular calcium through N-type calcium channels. Their activation limits the firing frequency of action potentials and is important for regulating afterhyperpolarization in the neurons of the central nervous system as well as many other types of electrically excitable cells. This is accomplished through the hyperpolarizing leak of positively charged potassium ions along their concentration gradient into the extracellular space. This hyperpolarization causes the membrane potential to become more negative. SK channels are thought to be involved in synaptic plasticity and therefore play important roles ...

Sangguniang Kabataan
A Sangguniang Kabataan (abbreviated as SK; ) is a community council that represents the youth in a barangay in the Philippines. Established to provide young people with a platform for civic engagement and participation in Local government in the Philippines, local governance, the SK is composed of elected officials aged 18 to 24, including a chairperson and several councilors. Its primary mandate is to initiate, plan, and implement programs, projects, and activities that promote the welfare and development of youth within the barangay. Under the SK Reform Law of 2016, or Republic Act No. 10742, the age requirement for SK officials was raised from 15–17 years old to 18–24 years old to ensure legal accountability and capacity to enter into contracts. Despite this change, the age range for eligible SK voters remains 15–30 years old. The SK is allotted 10 percent of the barangay's annual budget, which is earmarked exclusively for youth development initiatives. These may inc ...

SKI Combinator Calculus
The SKI combinator calculus is a combinatory logic system and a computational system. It can be thought of as a computer programming language, though it is not convenient for writing software. Instead, it is important in the mathematical theory of algorithms because it is an extremely simple Turing complete language. It can be likened to a reduced version of the untyped lambda calculus. It was introduced by Moses Schönfinkel and Haskell Curry. All operations in lambda calculus can be encoded via abstraction elimination into the SKI calculus as binary trees whose leaves are one of the three symbols S, K, and I (called ''combinators''). Notation Although the most formal representation of the objects in this system requires binary trees, for simpler typesetting they are often represented as parenthesized expressions, as a shorthand for the tree they represent. Any subtrees may be parenthesized, but often only the right-side subtrees are parenthesized, with left associativity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SK Radar
SK was an American-made Air search radar, air-search radar used during World War II by the United States Navy. Models included SK-1, SK-2 and SK-3. Overview SK was a very high frequency search set for large ships. It furnished range and bearing of surface vessels and aircraft, and it could be used for control of interception. The set had both "A" and Plan position indicator, PPI scopes, provisions for operating with remote PPIs and for Identification friend or foe, IFF connections, and built-in BL and BI Antenna (radio), antennas. With the antenna at , SK could detect medium bombers at altitude at . Range accuracy was ± and azimuth accuracy ± 3°. There was no elevation control, but elevation could be estimated roughly from positions of maximum and minimum signal strength. Shipment for SK included spares, with tubes for 400 hours, and a separate generator if the ship's power is Direct current, DC. SK was not air transportable. SK had 10 components weighing approximately . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SK (people Mover)
The SK is a people mover built by the company Soulé from Bagnères-de-Bigorre. The initialism ''SK'' comes from the initials of the production company, Soulé, and of the designer, Kermadec. The system consists of small cabins mounted on rails which are pulled by a cable at a constant speed. This idea is directly derived from the gondola lifts which Soulé produces for many ski resorts. At stations, the cabin drops the cable and can stop. This technique only works on short lines; its inability to work on long or curved lines with many stops is due to risk of losing the cable and lack of stability at normal speed. Deployed systems include the following: * The system operated at the parking lot of the exhibition grounds of Villepinte in 1986 *An SK system operated for a period of six months at Expo 86 *In 1989, an SK system operated at an exposition in Yokohama, Japan * An SK line was completed in February 1993 in Noisy-le-Grand but the office park it was supposed to ser ...
