Nonwovens are a type of textile that possess wide range unique properties, such as lightweight and damping characteristics, which make them suitable for many applications in medicine engineering. In this study, the focus lies on mechanical response nonwovens multiphase porous layer excited by an underlying vibrating plate. The material properties characterized via laboratory measurements applie...

In order to satisfactorily reproduce the Soil-Structure Interaction (SSI) effects under earthquake loading, it is often necessary to model a large domain of the soil surrounding the structure of interest. High spatial/temporal resolution is another challenge in analyzing these models. A new parallel nonlinear finite element program, ParCYCLIC, is employed to study such high fidelity large-scale...

In this study, the analytical modeling of one-dimensional consolidation by vertical drains with vacuum preloading considering both vertical and horizontal drainage is presented. In this method, the total degree of consolidation based on excess pore water pressure dissipation is related to the time factor (Th), drain configuration and anisotropic soil permeability. The analytical predictions are...

In saturated fine-grained soil, the development and dissipation of excess pore water pressure (EPWP) during after pile jacking change effective stress surrounding thereby affect set-up. this paper, entire process steel-pipe (the installation subsequent consolidation phase) is simulated with three-dimensional (3D) finite element models, considering effect. After model verification, a comprehensi...

This paper presents the experimental study of liquefaction potential for sandy soil in Prambanan Area, Yogyakarta, Indonesia, which underwent due to Mw 6.3 Jogja Earthquake on May 27, 2006. Shaking table tests considering variation acceleration and shaking duration were performed investigate sand. The time stages including start liquefaction, pore pressure dissipation, observed. percentage incr...

The mitochondrial inner membrane contains a Ca(2+)-activated pore of possible relevance to the pathogenesis of ischaemia/reperfusion injury which is inhibited by the immunosuppressant cyclosporin A (CSA). The present study employs a number of novel cobaltammine complex inhibitors of the Ca2+ uniporter (mediating Ca2+ uptake) to examine whether intramitochondrial Ca2+ influences the capacity of ...

the goal of this laboratory study is to investigate the effect of pore shapes on seismic wave velocities in carbonate rocks under reservoir conditions. in this research, 41 core plugs of carbonate rocks from oil fields of the southwest of iran were prepared. the compressional and shear wave velocities were measured in both dry and brine saturated samples under several pressures especially reser...

With asymptotic and numerical analyses, we systematically study the influence of slip length and access Ohmic resistance (due to pore-end field focusing and concentration polarization) on the energy conversion efficiency of pressure-driven electrolyte flow through a charged nanopore. Hydrodynamic slip reduces the percent of energy dissipated by viscous dissipation but, through electro-osmotic c...

Some landslides move imperceptibly downslope, whereas others accelerate catastrophically. Experimental landslides triggered by rising pore water pressure moved at sharply contrasting rates due to small differences in initial porosity. Wet sandy soil with porosity of about 0.5 contracted during slope failure, partially liquefied, and accelerated within 1 second to speeds over 1 meter per second....

There are two main approaches for pore pressure estimation: geological using basin modeling and geophysical using seismic velocity. In this paper, seismic velocity was used for pore pressure estimation. The impact of the input data quality in terms of signal-to-noise ratio (SNR) and frequency bandwidth on the accuracy of seismic velocity analysis and, ultimately, the reliability of pore pressur...
