Permeability

Despite rapid transport of water molecules in the non-oxidized regions of RGO channels, their weakly hydrophilic and narrow membrane channels could hamper the entry of water molecules into the channels, resulting in lower water permeability.

The government packed up the project after the three wells dug in the flanks of La Soufriere volcano failed to produce the permeability to access the energy necessary to generate electricity.

He said that the similarity between that well and the ones in St. Vincent is temperature, no permeability, temperature, no flow of water.

The soils competition involves calculating the slope of a field, identifying the sand to clay ratio of the soil, determining the permeability and run-off of the field, and then using that information to determine the land class of the field.

Future permeability studies should focus on low frequency effects and effects in humans.

Nanoemulsions are characterized by high bioavailability and permeability; it can potentially be used to encapsulate both water- and oil-soluble substances.

In previous studies, these scientists inspired in a peptide from bee venom, namely apamin, had made some chemical modifications and obtained a shuttle with BBB permeability.

Another method to control the inductance without any moving parts requires an additional DC current bias winding which controls the permeability of an easily saturable core material.

Because shale has matrix permeability too low to allow gas to flow in economical quantities, shale gas wells depend on fractures to allow the gas to flow.

Certain rock strata contain hydrocarbons but have low permeability and are not thick from a vertical perspective.

He notes that if permeability decreases with depth, a perched water table may develop in soils at intense precipitation.

Here, μ is the magnetic permeability of the material.

He then equated the ratio of the dielectric constant to the magnetic permeability with a suitably adapted version of Weber and Kohlrausch's result of 1856, and he substituted this result into Newton's equation for the speed of sound.

Hydraulic fracturing creates greater permeability and increases hydrocarbon flow to the wellbore.

If the aquifer is confined by low-permeability layers, the reduced water pressure in the sand and gravel causes slow drainage of water from the adjoining confining layers.

In this case the solutions are elliptically polarized electromagnetic waves with phase velocities (where μ is the magnetic permeability ).

It can also regulate specific gene expression, cellular secretion, and membrane permeability.

It increases the permeability of the soil to rainwater, thus decreasing runoff.

It is easy to select for reduced membrane permeability to chloramphenicol in vitro by serial passage of bacteria, and this is the most common mechanism of low-level chloramphenicol resistance.

Karst formations are cavernous and therefore have high rates of permeability, resulting in reduced opportunity for contaminants to be filtered.
