Bacterial Initiation Factor 2
Bacterial initiation factor-2 is a bacterial initiation factor. IF2 binds to an initiator tRNA and controls the entry of tRNA onto the ribosome. IF2, bound to GTP, binds to the 30S P site. After associating with the 30S subunit, fMet-tRNAf binds to the IF2 then IF2 transfers the tRNA into the partial P site. When the 50S subunit joins, it hydrolyzes GTP to GDP Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced and sold (not resold) in a specific time period by countries. Due to its complex and subjective nature this measure is of ... and Pi, causing a conformational change in the IF2 that causes IF2 to release and allow the 70S ribosome to form. Human mitochondria use a nuclear-encoded homolog, MTIF2, for translation initiation. References {{GTPases Molecular biology Protein biosynthesis Gene expression ...

International Fujita Scale
The International Fujita scale (abbreviated as IF-Scale) rates the intensity of tornadoes and other wind events based on the severity of the damage they cause. It is used by the European Severe Storms Laboratory (ESSL) and is being worked on by various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency (AEMET). The scale is intended to be analogous to the Fujita and Enhanced Fujita scales, while being more applicable internationally by accounting for factors such as differences in building codes. The International Fujita scale was drafted in 2018. International Fujita scale parameters The 12 categories for the International Fujita scale are listed below, in order of increasing intensity. Although the wind speeds and photographic damage examples are updated, which are more or less still accurate. However, for the actual IF-scale in practice, damage indicators (the type of structure which has been damaged) are predominantly used in det ...

Interceptor Force 2
''IF2: Interceptor Force 2'', commonly called ''Interceptor Force 2'', is a 2002 Sci Fi Pictures science-fiction TV movie on the Sci Fi Channel. A sequel to the 1999 Sci Fi Channel telefilm '' Interceptor Force'', it is directed by Phillip Roth, and stars Olivier Gruner, Roger R. Cross, Adrienne Wilkinson, Elizabeth Gracen and Nigel Bennett. Government-trained soldiers called the Interceptors are assigned to look at a crash site of an alien spacecraft in Russia where they find a alien that can change shape. Plot Over Grozny, Russia, a pair of fighter jets chase down an unidentified spacecraft moving at supersonic speeds. Within minutes, it is the jets that are chased and eventually blasted out of the sky by the spacecraft. Minutes later, residents report a "meteor" flying past the city and landing somewhere in the distant hills. Jack Bavaro, head of the Alpha Force, calls in Lieutenant Sean Lambert, the sole survivor of the first Alpha mission four years ago in Mexico. Lambert' ...

International Foundation For Internal Freedom
Timothy Francis Leary (October 22, 1920 – May 31, 1996) was an American psychologist and author known for his strong advocacy of psychedelic drugs. Evaluations of Leary are polarized, ranging from bold oracle to publicity hound. He was "a hero of American consciousness", according to Allen Ginsberg, and Tom Robbins called him a "brave neuronaut". As a clinical psychologist at Harvard University, Leary founded the Harvard Psilocybin Project after a revealing experience with magic mushrooms in Mexico. He led the Project from 1960 to 1962, testing the therapeutic effects of lysergic acid diethylamide (LSD) and psilocybin, which were legal in the U.S., in the Concord Prison Experiment and the Marsh Chapel Experiment. Other Harvard faculty questioned his research's scientific legitimacy and ethics because he took psychedelics along with his subjects and allegedly pressured students to join in. One of Leary's students, Robert Thurman, has denied that Leary pressured unwilling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IFF (other)
In logic and related fields such as mathematics and philosophy, "if and only if" (shortened as "iff") is a biconditional logical connective between statements, where either both statements are true or both are false. The connective is biconditional (a statement of material equivalence), and can be likened to the standard material conditional ("only if", equal to "if ... then") combined with its reverse ("if"); hence the name. The result is that the truth of either one of the connected statements requires the truth of the other (i.e. either both statements are true, or both are false), though it is controversial whether the connective thus defined is properly rendered by the English "if and only if"—with its pre-existing meaning. For example, ''P if and only if Q'' means that ''P'' is true whenever ''Q'' is true, and the only case in which ''P'' is true is if ''Q'' is also true, whereas in the case of ''P if Q'', there could be other scenarios where ''P'' is true and ''Q'' is ...
