In order to make medicine a more feasible career choice for women and in order to increase the level of training and, therefore, the quality of practice, it is important to decrease the scheduling rigidity of standard residency training programs. The steadily increasing numbers of women in medical school makes the problem more pressing at this time ...

Mean residence time in the body versus mean residence time in the central compartment
Journal of Pharmacokinetics and Biopharmaceutics, 1985Mean residence time in the body may be determined by noncompartmental methods following any type of input process into the sampled compartment. Mean residence time in the central compartment can be determined following an intravenous bolus dose, as it requires calculation of the concentration at zero time. For any other input process the mean residence

Chemical Physics Letters, 2010
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.

The intellectual roots of residence time theory date back to 1908 and, thus, span the 100-year history of Industrial & Engineering Chemistry. The theory was created, developed, and extended by chemical engineers. It permeates chemical engineering in general and chemical reaction engineering in particular.

Water, Air, and Soil Pollution, 1974
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 ...

Understanding Residence Time, Residence Time Distribution, and Impact of Surge Vessels
2020Axial dispersion and residence time distribution (RTD) have significant process implications in the design of continuous processes. Low dispersion is better for minimizing time for complete reaction and minimizing deviation boundaries. High dispersion is better for dampening out process fluctuations or disturbances.

In drug discovery, researchers think a lot about how tightly a small molecule binds to its target. For a long time, drug developers have considered tightly binding compounds better, more promising drug candidates than molecules that interact weakly with their targets.

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.
