| DIPI | defective interfering particle induction |
| D.I. particle | <abbreviation> Defective interfering particle. (05 Mar 2000) |
|---|---|
| dressed particle | <radiobiology> A particle plus its associated neutralising Debye sphere. (09 Oct 1997) |
| intramembranous particle | <cell biology> Particles (or complementary pits) seen in freeze fractured membranes. The cleavage plane is through the centre of the bilayer and the particles are usually assumed to represent Integral membrane proteins (or polymers of such proteins). (18 Nov 1997) |
| either particle flux density | The particle fluence rate, or energy flux density, the energy fluence rate of intensity. Compare: fluence. (05 Mar 2000) |
| elementary particle interactions | The interactions of particles responsible for their scattering and transformations (decays and reactions). Because of interactions, an isolated particle may decay into other particles. Two particles passing near each other may transform, perhaps into the same particles but with changed momenta (elastic scattering) or into other particles (inelastic scattering). Interactions fall into three groups: strong, electromagnetic, and weak. (12 Dec 1998) |
| trapped-particle instability | <radiobiology> Slowly-growing class of instabilities driven by particles which cannot circulate freely in a toroidal system. See: banana orbit. (09 Oct 1997) |
| kappa particle | <microbiology> Gram-negative bacterial endosymbiont of Paramoecium spp., (Caedobacter taeniospiralis) that confers the killer trait, infected Paramoecium are resistant to the toxin liberated by infected forms. Killing activity is associated with the induction of defective phage in the endosymbiont, leading to the release of R bodies, coded for by the phage genome and apparently of mis assembled phage coat protein. (18 Nov 1997) |
| Zimmermann's elementary particle | <haematology> A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels. Platelet _ granules contain lysosomal enzymes, dense granules contain ADP (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation. Synonym: thrombocytes. (09 Oct 1997) |
| adrenal weight factor | A postulated substance of adenohypophysial origin responsible for maintenance of the weight of the adrenal cortex. (05 Mar 2000) |
| apothecaries' weight | An obsolescent system of weights based upon the weight of a grain of wheat. Has been used for centuries in weighing medicines and precious metals (Troy measure). Some drugs which have been available for long periods are still often designated as grains (e.g., 5 grains of aspirin, 1/2 grain of codeine, 1/100 grain nitroglycerin). This weight system has been largely superseded by the metric system (based on grams). One grain is the equivalent of 64.8 milligrams. One scruple contains 20 grains; one dram contains 60 grains; one apothecary ounce contains 8 drams (480 grains); one apothecary pound contains 12 ounces (5760 grains). (05 Mar 2000) |
| atomic weight | <chemistry> The average weight of an atom of an element, i.e. The total mass of protons and neutrons in an atom. (09 Oct 1997) |
| birth weight | In humans, the first weight of an infant obtained within less than the first 60 completed minutes after birth; a full-size infant is one weighing 2500 g or more; a low birth weight is less than 2500 g. (05 Mar 2000) |
| body-weight ratio | Body weight (in grams) divided by stature (in centimeters). (05 Mar 2000) |
| gram-atomic weight | Atomic weight expressed in grams. Compare: mole. (05 Mar 2000) |
| gram-molecular weight | Molecular weight expressed in grams. Compare: mole. (05 Mar 2000) |
