Structural heterogeneity and permeability in faulted eolian sandstone: Implications for subsurface modeling of faults [PDF]

open access: yes, 2002
We determined the structure and permeability variations of a 4 km-long normal fault by integrating surface mapping with data from five boreholes drilled through the fault (borehole to tens of meters scale).

18 GHz electromagnetic field induces permeability of Gram-positive cocci [PDF]

open access: yesScientific Reports, 2015
AbstractThe effect of electromagnetic field (EMF) exposures at the microwave (MW) frequency of 18 GHz, on four cocci, Planococcus maritimus KMM 3738, Staphylococcus aureus CIP 65.8T, S. aureus ATCC 25923 and S. epidermidis ATCC 14990T, was investigated.

Loading rate dependence of permeability evolution in porous aeolian sandstones [PDF]

open access: yes, 2004
Mechanical properties of rocks are characterized by their notable dependence on the applied deformation rate. However, little is known about the strain rate dependence of fluid flow properties since most laboratory tests are conducted using a single ...

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

open access: yes, 2003
Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure. The log permeability

Sensitivity analysis of permeability parameters of bovine nucleus pulposus obtained through inverse fitting of the nonlinear biphasic equation : effect of sampling strategy [PDF]

open access: yes, 2012
Permeability controls the fluid flow into and out of soft tissue, and plays an important role in maintaining the health status of such tissue. Accurate determination of the parameters that define permeability is important for the interpretation of models

Dietary calcium decreases but short-chain fructo-oligosaccharides increase colonic permeability in rats [PDF]

open access: yes, 2010
An increased intestinal permeability is associated with several diseases. Nutrition can influence gut permeability. Previously, we showed that dietary Ca decreases whereas dietary short-chain fructo-oligosaccharides (scFOS) increase intestinal ...

Decision trees to characterise the roles of permeability and solubility on the prediction of oral absorption. [PDF]

open access: yes, 2015
Oral absorption depends on many physiological, physiochemical and formulation factors. Two important properties that govern oral absorption are in vitro permeability and solubility, which are commonly used as indicators of human intestinal absorption ...

New theories on electromagnetism and on light and colors

open access: yes, 2021
Completely new theories on two fields. 1) Electromagnetism 2) Light and colors The theories are based on very simple and very easily reproducible experiments, some of them, although simple, still very impressive and yet not known.
