permeability

The measure of a material's ability to transmit liquids.The passage of soil contaminants into groundwater increases as soil permeability increases.On the other hand,in situ remediation—removal or decomposition—of groundwater contamination is easier as permeability increases.For a color map of the United States showing the relative permeability of soils across the country, see the Web site page of the Environmental Protection Agency at www.epa.gov/iwi/1999sept/iv20_usmap.html.

to relate the pore space geometry to the permeability of waste in order to further understand the mechanics of the flow of gas and liquids through waste.
To predict the permeability of soil at 95% MDD, several regression analysis were carried out using the different variables and accuracy of each model was tested by comparing the predicted values with actual values.
The time-lag method was applied to determine the permeability of paint films to different gases saturated with humidity at 25[degrees]C for obtaining the pore size of the experimental coatings in these conditions.

There are guidelines for controlling permeability of coatings.
The tests for the permeability at water vapors were led with a Dansensor L80-5000 (PBI Dansensor), and the tests for the permeability at gases were led with a Dansensor L100-5000 (PBI Dansensor).

The advantage of using gas permeabilities to determine hydraulic conductivity is that in situ gas permeability measurements can be undertaken much more readily than corresponding water determinations, enabling more extensive surveys to be undertaken in the field.
Elevated vascular permeability because of a damaged blood-brain barrier after ischemic stroke can be quantified with perfusion computed tomography (CT), a technique that rapidly evaluates cerebral perfusion by generating maps of cerebral blood flow, cerebral blood volume, and mean transit time.
