| temperature coefficient | The fractional change in any physical property per degree rise in temperature. (05 Mar 2000) |
|---|---|
| economic coefficient | In growth and cultivation of microorganisms, the ratio of the mass produced to the substrate consumed. (05 Mar 2000) |
| Jaccard coefficient | <zoology> An association coefficient used in numerical taxonomy, it is the proportion of characters that match, excluding those that both organisms lack. (12 Jan 1998) |
| extinction coefficient | <chemistry> A constant used in the Beer-Lambert Law which relates the concentration of the substance being measured (in moles) to the absorbance of the substance in solution (how well the substance in solution blocks light beamed through it from getting out on the other side). (09 Oct 1997) |
| extraction coefficient | The percentage of a substance removed from the blood or plasma in a single passage through a tissue; e.g., the extraction coefficient for p-aminohippuric acid (PAH) in the kidney is the difference between arterial and renal venous plasma PAH concentrations, divided by the arterial plasma PAH concentration. (05 Mar 2000) |
| ultrafiltration coefficient | The filtration coefficient of a semipermeable membrane. (05 Mar 2000) |
| filtration coefficient | A measure of a membrane's permeability to water; specifically, the volume of fluid filtered in unit time through a unit area of membrane per unit pressure difference, taking into account both hydraulic and osmotic pressures. (05 Mar 2000) |
| lethal coefficient | <microbiology> That concentration of disinfectant that kills bacteria at 20-25캜 in the shortest period of time. (05 Mar 2000) |
| Long's coefficient | A formula for estimating from the specific gravity of a specimen of urine the approximate amount of solids in grams per liter; the last two figures of the value for specific gravity are multiplied by 2.6. Synonym: Long's coefficient. (05 Mar 2000) |
