| standard substance | A pure, authentic substance used for identification purposes. (05 Mar 2000) |
|---|---|
| standard temperature | A temperature of 0캜 or 273.15 |
| standard urea clearance | The value obtained when the square root of the urine flow (when below 2 ml/min) is multiplied by the urine urea concentration and divided by the whole blood urea concentration; represents an old empirical adjustment for the effect of low urine flow on urea excretion; sometimes corrected for body size by dividing by some function of body weight or surface area. Later, plasma concentration was substituted for blood concentration in the calculation. The normal value is about 54 ml/min per 1.73 m2 in an adult person. Synonym: Van Slyke's formula. (05 Mar 2000) |
| standard volume | The volume of an ideal gas at standard temperature and pressure, approximately 22.414 liters. (05 Mar 2000) |
| standard-wing | <zoology> A curious paradise bird (Semioptera Wallacii) which has two long special feathers standing erect on each wing. Source: Websters Dictionary (01 Mar 1998) |
| ICAO standard atmosphere | The standard atmosphere adopted by the International Civil Aviation Organization, used for calibrating altimeters and for expressing hypobaric chamber pressures in terms of equivalent altitude; it ignores many deviations found in nature. (05 Mar 2000) |
| emission standard | This regulatory value is a quantitative limit on the emission or discharge of a potentially toxic substance from a source. The simplest form for regulatory purposes is a uniform emission standard (UES) where the same limit is placed on all emissions of a particular contaminant. (09 Oct 1997) |
| environmental quality standard | This regulatory value defines the maximum concentration of a potentially toxic substance which can be allowed in an environmental compartment, usually air (air quality standard - AQS) or water, over a defined period. (09 Oct 1997) |
| active length-tension curve | The relationship between active isometric tension and preload (rest length) for a contracting muscle. (05 Mar 2000) |
| alignment curve | The line passing through the centre of the teeth laterally in the direction of the curve of the dental arch. (05 Mar 2000) |
| anti-Monson curve | In dentistry, a curve of occlusion which is convex upward. Synonym: anti-Monson curve. (05 Mar 2000) |
| area under curve | A statistical means of summarizing information from a series of measurements on one individual. It is frequently used in clinical pharmacology where the auc from serum levels can be interpreted as the total uptake of whatever has been administered. As a plot of the concentration of a drug against time, after a single dose of medicine, producing a standard shape curve, it is a means of comparing the bioavailability of the same drug made by different companies. (12 Dec 1998) |
| area under the curve | A measure of how much of a drug reaches the bloodstream in a set period of time, usually 24 hours. AUC is calculated by plotting drug blood concentration at various times during a 24-hour or longer period and then measuring the area under the curve between 0 and 24 hours as shown in the figure to the right. (09 Oct 1997) |
| Barnes' curve | A curve corresponding in general with Carus' curve, being the segment of a circle whose centre is the promontory of the sacrum. (05 Mar 2000) |
| biphasic growth curve | <cell culture, microbiology> A particular type of growth curve seen in cultured microorganisms in which they have two exponential growth stages separated by a plateau phase. This double-hump curve is produced when the microbes are cultured using two carbon sources, one of which must be used up before the second can be used. (19 Jan 1998) |
