Abstract The residence time of a diffusing particle in a prescribed spatial region recently finds an increasing number of applications in physics and chemistry. A partial differential equation for the residence time moments is derived, as a generalization of the ordinary differential equation for the first passage time moments.

For a batch reaction, the conditions within a reactor (the concentrations of materials and products) change with time. In contrast, for a flow reaction, the conditions within a reactor remain constant with time, but the conditions differ at different locations within the reactor.

Methods and findings in experimental and clinical pharmacology, 1986
The definition of mean residence time in the strict sense of mathematical statistics is deduced. It is demonstrated that the area-normalized concentration time curve is an estimate of the probability density function for residence times of drug molecules in the pharmacokinetic system, provided that the area under the concentration-time profile is ...

Examination of suspended particulate concentration data from a year-long, regional air-quality study of a portion of the Great Lakes area revealed that depletion of particulates occurred during extended periods of travel over water surfaces. Based on particulate concentrations and meteorological measurements, residence times of background regional ...
