| voiding flow rate | Urinary flow as a function of time during micturition, as graphically recorded by a flow meter. (05 Mar 2000) |
|---|---|
| volume loading rate | The rate of raw materials put into a fermenter or aerobic digester, expressed in terms of material weight per unit volume per unit time. (09 Oct 1997) |
| respiration rate | Frequency of breathing, recorded as the number of breaths per minute. (05 Mar 2000) |
| respiratory rate | The number of breaths per minute (or, more formally, the number of movements indicative of inspiration and expiration per unit time). In practice, the respiratory rate is usually determined by counting the number of times the chest rises (or falls) per minute. By whatever means, the aim is to determine if the respirations are normal, abnormally fast (tachypnea), abnormally slow (technically termed bradypnea), or nonexistent (apnea). (12 Dec 1998) |
| response rate | <oncology> The percentage of patients showing partial or complete response to the given treatment. (16 Dec 1997) |
| per capita rate | <epidemiology> A rate which is proportional to the number of individuals in a population. (05 Dec 1998) |
| metabolic clearance rate | Volume of biological fluid completely cleared of drug metabolites as measured in unit time. Elimination occurs as a result of metabolic processes in the kidney, liver, saliva, sweat, intestine, heart, brain, or other site. (12 Dec 1998) |
| gross reproduction rate | The average number of female children a woman would have if she survived to the end of her childbearing years and if, throughout that period, she were subject to a given set of age-specific fertility rates and a given sex ratio at birth; this rate provides a measure of the replacement fertility of a population in the absence of mortality. (05 Mar 2000) |
| growth rate | <biology, cell culture, ecology> The rate, or speed, at which the number of organisms in a population increases. This can be calculated by dividing the change in the number of organisms from one point in time to another by the amount of time in the interval between the points of time. The phrase is most often used to describe growth of cells or microorganisms in laboratory cultures and usually expressed as the generation time. (21 Jun 2000) |
| growth rate of population | <epidemiology> A measure of population change in the absence of migration, comprising addition of newborns and subtraction of deaths; the result is known as the natural rate of increase of the population; it is the difference between the crude birth rate and the crude death rate. (05 Mar 2000) |
| mitotic rate | The proportion of cells in a tissue that are undergoing mitosis, expressed as a mitotic index or, roughly, as the number of cells in mitosis in each microscopic high-power field in tissue sections. (05 Mar 2000) |
| morbidity rate | The sickness rate, the number of people who are sick or have a disease compared with the number who are well. (09 Oct 1997) |
| concordance rate | The proportion of a random sample of pairs that are concordant for a trait of interest. A high rate of concordance may be generated in several ways, many of which may result from irrelevant bias; but broadly it is taken as evidence of causal connection (e.g., in the case of identical twins, a genetic component or in spouses of assortative mating). (05 Mar 2000) |
| contact rate | <epidemiology> The rate at which susceptibles meet infecteds. Usually measured as individuals per unit time. (05 Dec 1998) |
| mutation rate | The frequency with which a particular mutation appears in a population or the frequency with which any mutation appears in the whole genome of a population. Normally the context makes the precise use clear. See: fluctuation analysis. (18 Nov 1997) |
