Physiologically Based Structure of Mean Residence Time [PDF]

open access: yesThe Scientific World Journal, 2012
A mean residence time (MRT) is an important pharmacokinetic parameter. To the author's knowledge, however, a physiologically based structure of MRT (thereafter MRT structure) has not been published so far.

On the Mean Residence Time in Stochastic Lattice-Gas Models [PDF]

open access: yesJournal of Statistical Physics, 2018
A heuristic law widely used in fluid dynamics for steady flows states that the amount of a fluid in a control volume is the product of the fluid influx and the mean time that the particles of the fluid spend in the volume, or mean residence time. We rigorously prove that if the mean residence time is introduced in terms of sample-path averages, then ...

Mean residence time for drugs subject to reversible metabolism

open access: yesJournal of Pharmacy and Pharmacology, 1987
Abstract Conventional methods based on moment analysis lead to biased estimates of the mean residence time for drugs subject to reversible metabolism. A stochastic approach is described which enables unbiased estimation of the mean residence time.

Evaluation of Residence Time on Nitrogen Oxides Removal in Non-Thermal Plasma Reactor. [PDF]

open access: yesPLoS ONE, 2015
Non-thermal plasma (NTP) has been introduced over the last few years as a promising after- treatment system for nitrogen oxides and particulate matter removal from diesel exhaust. NTP technology has not been commercialised as yet, due to its high rate of

Mean sediment residence time in barchan dunes [PDF]

open access: yesJournal of Geophysical Research: Earth Surface, 2014
When a barchan dune migrates, the sediment trapped on its lee side is later mobilized when exposed on the stoss side. Then sand grains may undergo many dune turnover cycles before their ejection along the horns, but the amount of time a sand grain contributes to the dune morphodynamics remains unknown.

Liquid mean residence time (MRT) in rotating packed bed (RPB) by empirical correlation and residence time distribution (RTD) method using computational fluid dynamics (CFD) simulation [PDF]

open access: yesMATEC Web of Conferences, 2023
Rotating packed bed (RPB) belongs to a HIGee technology, a process intensification device that can provide better mass transfer rate due to the generation of hyper-gravity under the influence of centrifugal force.

Depth to water table correction for initial carbon-14 activities in groundwater mean residence time estimation [PDF]

open access: yesHydrology and Earth System Sciences, 2021
Carbon-14 (14C) is routinely used to determine mean residence times (MRTs) of groundwater. 14C-based MRT calculations typically assume that the unsaturated zone is in equilibrium with the atmosphere, controlling the input 14C activity.

Estimating Mean Residence Time of Groundwater in Central Basin/Erbil using Environmental Isotopes

open access: yesZanco Journal of Pure and Applied Sciences, 2023
The average time of input water needs to recharge the groundwater basin and reach a catchment outlet, whether it follows a vertical or horizontal flow direction, is known as the mean residence time (MRT).
