Permeability identification of a weakly permeable partially saturated porous rock
Transport in Porous Media, 2006The present paper deals with the determination of permeability in partially saturated conditions for weakly permeable porous continua such as argillites or deep clayey formations. The permeability can be deduced from measurements of transient weight loss of a sample submitted to a laboratory drying test: a decrease of relative humidity is imposed by ...

Social identification and permeability of group boundaries
European Journal of Social Psychology, 1988AbstractTwo experiments were conducted to investigate some of the factors affecting social identification. In Experiment 1 ingroup identification was measured for subjects who were members of high or low status groups with either permeable or impermeable boundaries, and who received high, average or low ability feedback.

Identification of the permeability distribution in soil by hydraulic tomography
Inverse Problems, 1995Summary: A tomographical method is presented that allows the reconstruction of the structure of soil layers between two boreholes. If the soil is water saturated, the transient field equation for pore water pressure \[ S(x) \partial_ t u(x,t)- \nabla\cdot (k(x) \nabla u(x,t)) =Q \] can be used to reconstruct the soil structure from its permeability \(k(

Identification of coal seam fractures and dominant orientation of permeability
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2020Coal seam permeability is a contributory factor for gas extraction and coal-bed methane (CBM) development, as its anisotropy is closely related to coal seam fractures.

Simultaneous identification of electric permittivity and magnetic permeability
Inverse Problems, 2010In this paper we investigate the simultaneous reconstruction of the electric permittivity and magnetic permeability. The two physical parameters are allowed to be highly discontinuous in the concerned physical domain. The ill-posed inverse problem is formulated into an output least-squares nonlinear minimization with BV-regularization. The regularizing

Identification of a Site in Glutamate Receptor Subunits That Controls Calcium Permeability
Science, 1991The neurotransmitter glutamate mediates excitatory synaptic transmission throughout the brain. A family of genes encoding subunits of the non- N -methyl-D-aspartate (non-NMDA) type of glutamate receptor has been cloned.

Identification of a molecular target for glutamate regulation of astrocyte water permeability
Glia, 2008AbstractAstrocytes play a key role for maintenance of brain water homeostasis, but little is known about mechanisms of short‐term regulation of astrocyte water permeability. Here, we report that glutamate increases astrocyte water permeability and that the molecular target for this effect is the aquaporin‐4 (AQP4) serine 111 residue, which is in a ...

Support-Operators Method in the Identification of Permeability Tensor Orientation
SPE Journal, 2000SummaryThe dependence of rock permeability on direction, or permeability anisotropy, is confirmed by numerous field examples. Therefore, the ability to carry out a numerical simulation of an anisotropic reservoir is very important. The support-operators method provides a conservative discretization scheme, allowing one to solve nonisotropic problems on
