| drift velocity | <radiobiology> Characteristic velocity at which the centre of a particle's orbit (guiding centre) drifts when drift motion (see above) occurs. (09 Oct 1997) |
|---|---|
| initial velocity | The rate of a reaction, e.g., an enzyme-catalyzed reaction, at the early stages of the reaction such that the product(s) concentrations have not risen to a level to significantly affect the observable rate; typically, initial velocities are observed when less than 10% of the reaction's approach toward equilibrium has occurred. Synonym: initial rate. (05 Mar 2000) |
| thermal velocity | <radiobiology> Average speed (magnitude of velocity) of a particle at a given temperature (in a Maxwellian velocity distribution). (09 Oct 1997) |
| electron velocity | <physics> The rate of motion of an electron. (05 Aug 1998) |
| fish velocity | The velocity at the location occupied by a fish, measured at the fish's snout. (09 Oct 1997) |
| force-velocity curve | The relationship between isotonic velocity of shortening and afterload for a contracting muscle. (05 Mar 2000) |
| allantoic fluid | The fluid within the allantoic cavity. (05 Mar 2000) |
| amniotic fluid | <anatomy, obstetrics> The fluid that surrounds the developing foetus within the amniotic sac. This environment cushions the baby from injury and plays an important role in foetal development. (05 Feb 1998) |
| amniotic fluid embolism | Obstruction and constriction of pulmonary blood vessels by amniotic fluid entering the maternal circulation, causing obstetric shock. See: amniotic fluid syndrome. (05 Mar 2000) |
| amniotic fluid syndrome | <syndrome> Pulmonary embolic phenomena thought to be due to infusion of amniotic fluid containing epithelial squames into maternal blood vessels; shock ensues and sudden death may occur. (05 Mar 2000) |
| ascitic fluid | The serous fluid which accumulates in the peritoneal cavity in ascites. (12 Dec 1998) |
| blood-cerebrospinal fluid barrier | A barrier located at the tight junctions which surround and connect the cuboidal epithelial cells on the surface of the choroid plexus; capillaries and connective tissue stroma of the choroid do not represent a barrier to protein tracers or dyes. (05 Mar 2000) |
| body fluid compartments | The two phases between which water and other body fluids are distributed: extracellular and intracellular. (12 Dec 1998) |
| Brodie fluid | An aqueous salt solution used in manometers designed for testing gas evolution or uptake, as in cell respiration. (05 Mar 2000) |
| bronchoalveolar lavage fluid | Fluid obtained by washout of the alveolar compartment of the lung. It is used to assess biochemical and inflammatory changes in and effects of therapy on the interstitial lung tissue. (12 Dec 1998) |
