Periodic pressure measurements made during the depletion of oil fields and virgin pressure measurements through normallyand over-pressured sequences in sedimentary basins both demonstrate that changes in pore pressure and minimum horizontal stress (σh) are coupled to one another. Pore pressure/stress coupling is predicted by poroelastic theory. Data from the North Sea (Ekofisk Field) and Texas ...

Capacitive deionization (CDI) is a promising desalination technology, which operates at low pressure, low temperature, requires little infrastructure, and has the potential to consume less energy for brackish water desalination. However, CDI devices consume significantly more energy than the theoretical thermodynamic minimum, and this is at least partly due to resistive power dissipation. We he...

Introduction: The consolidation behavior of horizontal drainage foundation under complex aquifer conditions in karst areas is a hot topic the field geotechnical engineering. Methods: This paper presents modified piecewise-linear model for plane-strain consolidation. In this model, distributed boundary was used to describe performance soil layer boundaries, and UH considering time effect selecte...

A better understanding of the wave-induced pore pressure accumulations (i.e., residual pore pressure) is a key factor in the analysis of the wave-induced liquefaction in marine sediments. In this paper, the residual mechanism of nonlinear wave-induced pore water pressure accumulation in marine sediments is examined. Unlike previous investigations, the second-order Stokes wave theory is consider...

this paper presents the results of a series of monotonic and post-cyclic triaxial tests carried out on a clay specimen and three types of clay-sand mixed specimens. the focus of the paper is on the post-cyclic mechanical behavior of the mixed specimens, as compared to their monotonic behavior. analyses of the tests results show that cyclic loading degrade undrained shear strength and deformatio...

Based on the shaking table test, liquefaction of silt under earthquake load and damage after are studied. The test results show that lower is relatively dense, pore pressure increases slowly, ratio can not reach initial state. However, stronger action, dense may also produce liquefaction, which indicates increase water has a great relationship with compactness intensity load. Because permeabili...

When a nonwetting fluid is forced to infiltrate a hydrophobic nanoporous solid, the external mechanical work is partially dissipated into thermal energy and partially converted to the liquid-solid interface energy to increase its enthalpy, resulting in a system with a superior energy absorption performance. To clarify the energy dissipation and conversion mechanisms, experimental infiltration a...

Induction of the nonselective cyclosporin-sensitive pore in the inner mitochondrial membrane under conditions of complete dissipation of ion gradients and transmembrane potential was studied. This approach allows the kinetics of Ca2+-dependent pore opening and the preceding processes of induction to be studied separately. The effects of mitochondrial heterogeneity were also minimized. We found ...
