The spiral design can be based on interlocking Archimedean spirals , or represent three bent human limbs. It occurs in artifacts of the ... | https://en.wikipedia.org/wiki/Triskelion |
A Trisonic Wind Tunnel ( TWT ) is a wind tunnel so named because it is capable of testing in three speed regimes – subsonic , transonic , and supersonic . The earliest known trisonic wind tunnel was dated to 1950 and was located in El Segundo, California before it closed in 2007. [ 1 ] [ 2 ] Other trisonic wind tunnels... | https://en.wikipedia.org/wiki/Trisonic_Wind_Tunnel |
Trisoxazolines (Often abbreviated TRISOX or TOX ) are a class of tridentate , chiral ligands composed of three oxazoline rings. Despite being neutral they are able to form stable complexes with high oxidation state metals, such as rare earths , [ 1 ] due to the chelate effect . The ligands have been investigated for mo... | https://en.wikipedia.org/wiki/Trisoxazolines |
Tristar and Red Sector Incorporated ( TRSI ) is a demogroup which formed in 1990. It came about from the longest-running cooperation in scene history. [ 1 ] RSI existed from 1985, before being joined by the "T" later on. Evolving from the Commodore 64 to the Amiga and later to PC and various game console platforms - li... | https://en.wikipedia.org/wiki/Tristar_and_Red_Sector_Incorporated |
Trithorax-group proteins ( TrxG ) are a heterogeneous collection of proteins whose main action is to maintain gene expression . They can be categorized into three general classes based on molecular function:
plus other TrxG proteins not categorized in the first three classes. [ 1 ]
The founding member of TrxG protein... | https://en.wikipedia.org/wiki/Trithorax-group_proteins |
Tritium (from Ancient Greek τρίτος (trítos) ' third ' ) or hydrogen-3 (symbol T or 3 H ) is a rare and radioactive isotope of hydrogen with a half-life of ~12.33 years. The tritium nucleus (t, sometimes called a triton ) contains one proton and two neutrons , whereas the nucleus of the common isotope hydrogen-1 ( proti... | https://en.wikipedia.org/wiki/Tritium |
Tritium radioluminescence is the use of gaseous tritium , a radioactive isotope of hydrogen , to create visible light. Tritium emits electrons through beta decay and, when they interact with a phosphor material, light is emitted through the process of phosphorescence . The overall process of using a radioactive materia... | https://en.wikipedia.org/wiki/Tritium_radioluminescence |
Tritrophic interactions in plant defense against herbivory describe the ecological impacts of three trophic levels on each other: the plant, the herbivore , and its natural enemies. They may also be called multitrophic interactions when further trophic levels , such as soil microbes, endophytes , or hyperparasitoids (h... | https://en.wikipedia.org/wiki/Tritrophic_interactions_in_plant_defense |
Trituration (Latin, grinding ) is the name of several different methods used to process materials. In one sense, it is a form of comminution (reducing the particle size of a substance). In another sense, it is the production of a homogeneous powdered material by mixing and grinding component materials thoroughly. [ 1 ]... | https://en.wikipedia.org/wiki/Trituration |
The triune brain was a once popular, now proven false, [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] model of the evolution of the vertebrate forebrain and behavior, proposed by the American physician and neuroscientist Paul D. MacLean in the 1960s. The triune brain consists of the reptilian complex ( basal ganglia ), the paleomammali... | https://en.wikipedia.org/wiki/Triune_brain |
The triune continuum paradigm ( triune : "both three and one at the same time") is a paradigm for general system modeling published in 2002. [ 1 ] The paradigm allows for building of rigorous conceptual frameworks employed for systems modeling in various application contexts (highly tailored as well as interdisciplinar... | https://en.wikipedia.org/wiki/Triune_continuum_paradigm |
Triuret is an organic compound with the formula (H 2 NC(O)NH) 2 CO. It is a product from the pyrolysis of urea . Triuret is a colorless, crystalline, hygroscopic solid, slightly soluble in cold water or ether, and more soluble in hot water. It is a planar molecule. The central carbonyl is hydrogen-bonded to both termi... | https://en.wikipedia.org/wiki/Triuret |
A trivalent group 14 radical (also known as a trivalent tetrel radical ) is a molecule that contains a group 14 element (E = C, Si, Ge, Sn, Pb) with three bonds and a free radical , having the general formula of R 3 E•. Such compounds can be categorized into three different types, depending on the structure (or equival... | https://en.wikipedia.org/wiki/Trivalent_group_14_radicals |
In evolutionary biology and evolutionary psychology , the Trivers–Willard hypothesis , [ 1 ] formally proposed by Robert Trivers and Dan Willard in 1973, suggests that female mammals adjust the sex ratio of offspring in response to maternal condition , so as to maximize their reproductive success ( fitness ). For examp... | https://en.wikipedia.org/wiki/Trivers–Willard_hypothesis |
In chemistry , a trivial name is a non- systematic name for a chemical substance . That is, the name is not recognized according to the rules of any formal system of chemical nomenclature such as IUPAC inorganic or IUPAC organic nomenclature. A trivial name is not a formal name and is usually a common name .
Generally... | https://en.wikipedia.org/wiki/Trivial_name |
In the mathematical field of representation theory , a trivial representation is a representation ( V , φ ) of a group G on which all elements of G act as the identity mapping of V . A trivial representation of an associative or Lie algebra is a ( Lie ) algebra representation for which all elements of the algebra act a... | https://en.wikipedia.org/wiki/Trivial_representation |
In topology , a topological space with the trivial topology is one where the only open sets are the empty set and the entire space. Such spaces are commonly called indiscrete , anti-discrete , concrete or codiscrete . Intuitively, this has the consequence that all points of the space are "lumped together" and cannot be... | https://en.wikipedia.org/wiki/Trivial_topology |
