| effective osmotic pressure | That part of the total osmotic pressure of a solution that governs the tendency of its solvent to pass across a boundary, usually a semipermeable membrane; it is commonly represented by the product of the total osmotic pressure of the solution and the ratio (corrected for activities) of the number of dissolved particles that do not permeate the bounding membrane to the total number of particles in the solution; equivalent in meaning to tonicity; commonly expressed in equivalent units of osmolality rather than pressure per se.

| effective refractory period | The period during which impulses may appear but are too weak to be conducted; the longest interval between adequate stimuli, falling just short of the time necessary to allow a propagated response to be evoked in a tissue by the second stimulus; it differs from the functional refractory period in that it is a measure of stimulus interval rather than response interval of time. (05 Mar 2000) |
| effective renal blood flow | The amount of blood flowing to the parts of the kidney that are involved with production of constituents of urine. (05 Mar 2000) |
| effective renal plasma flow | <physiology> The amount of plasma flowing to the parts of the kidney that have a function in the production of constituents of urine; the clearance of substances such as iodopyracet and p-aminohippuric acid, assuming that the extraction ratio in the peritubular capillaries is 100%. It is the amount of plasma perfusing the kidney tubules per unit time, generally measured by p-aminohippurate clearance. It should be differentiated from renal plasma flow which is approximately 10% greater than the effective renal plasma flow. (07 Mar 2000) |
| absolute temperature | Temperature reckoned in Kelvins from absolute zero. (05 Mar 2000) |
| basal body temperature | <biology> The temperature taken at its lowest point in the day, usually in the morning before getting out of bed. (09 Oct 1997) |
| body temperature changes | Any deviation from normal body temperature of the human body, about 98.6 degrees f. Or 37 degrees c. When taken orally. (12 Dec 1998) |
| maximum temperature | In bacteriology, denoting a temperature above which growth will not take place. (05 Mar 2000) |
| mean temperature | The average atmospheric temperature in any locality for a designated period of time, as a month or a year. (05 Mar 2000) |
| restrictive temperature | <molecular biology> Of a temperature sensitive mutation, a temperature at which the mutated gene product behaves normally and so the cell or organism survives as if wild type. C.f. The restrictive temperature, at which the gene product takes on a mutant phenotype. (18 Nov 1997) |
| melting temperature | The midpoint in the change in optical properties (absorbance, rotation) of a structured polymer (e.g., DNA) with increasing temperature. Synonym: melting temperature. (05 Mar 2000) |
| melting temperature of DNA | That temperature at which, under a given set of conditions, double-stranded DNA is changed (50%) to single-stranded DNA; under standard conditions, the base composition of the DNA can be estimated from the denaturation temperature, since the greater the denaturation temperature, the greater the guanine-plus-cytosine content (i.e., GC content) of the DNA. Synonym: melting temperature of DNA. (05 Mar 2000) |
| permissive temperature | <molecular biology> Of a temperature sensitive mutation, a temperature at which the mutated gene product behaves normally and so the cell or organism survives as if wild type. C.f. The restrictive temperature, at which the gene product takes on a mutant phenotype. (18 Nov 1997) |
| room temperature | The ordinary temperature (65 |
| minimum temperature | In bacteriology, denoting a temperature below which growth will not take place. (05 Mar 2000) |
