Two optimal control problems concerning a stirred continuous flow adsorber are studied, with temperature being the control variable: (i) minimize time at which a given amount is adsorbed, (ii) maximize time for which the outlet adsorbate concentration does not exceed a given level.
The liquid limit is the point at which a given amount of water added to a soil or clay converts it to a semi-fluid state; the plastic limit refers to the water content at which soil begins to crumble on being rolled into a 3 mm diameter thread.
In present assay the N/ P ratio of MCH to ODN was determined at which a given amount of ODN is completely complexed by MCH.
Compensatory response implies a series of plastic phenotypic changes in different traits that can determine the pattern of change in relative growth rate (RGR, the rate at which a given amount of existing biomass can produce new biomass per unit time; Shipley 2000) after defoliation (Oesterheld and McNaughton 1988; Trumble et al. 1993; Strauss and Agrawal 1999; Stowe et al. 2000; Tiffin 2000).
For the quantitative analysis, seven stock solutions containing the reference analytes at known concentrations and a given amount of anisole as internal standard were used.
The cytotoxin probably acts on the cell surface and is more effective at 40 degrees C than at 37 degrees C. For a given amount of cytotoxin the effects are inversely proportional to the target cell concentration.
Changing Effects of Alcohol Because the body that is consuming alcohol at 65 or beyond is not the same as the one that drank at 45, the effects of a given amount of alcohol can be greatly exaggerated in an older person.
(Options, for those unfamiliar with the term, are a way of paying someone in stock--that person has the option to purchase a certain amount of shares, at a certain price, for a given amount of time.
Conversely, a put option gives its holder the right to sell a given amount electricity at the strike price.
