We present a multiscale Bayesian method to reconstruct the permeability field of a binary medium. The reconstruction is conditioned on measurements of permeability and tracer test breakthrough times, observed at a limited set of locations. The medium consists of a spatially variable distribution of inclusions, which are too small to be individually resolved at the grid scale. The unknown inclus...

Coordinated contractile activation of the heart and resistance to ischemic injury depend, in part, on the intercellular communication mediated by Cx43-composed gap junctions. The function of these junctions is regulated at multiple levels (assembly to degradation) through phosphorylation at specific sites in the carboxyl terminus (CT) of the Cx43 protein. We show here that the selective permeab...

The proton-coupled oligopeptide transporter (PEPT1) has been shown to mediate mucosal cell transport of di- and tripeptide, and some peptidomimetic drugs. In this study, we determined the correlation between PEPT1 protein expression and the permeability of cephalexin, a substrate of PEPT1, in human PEPT1 (hPEPT1)-overexpressed Caco-2 cells (Caco-2/hPEPT1 cells) and rat jejunum. Caco-2/hPEPT1 ce...

Gas-separation membranes are a critical industrial component for low-carbon and energy-efficient future. As result, many researchers have been testing membrane materials over the past several decades. Unfortunately, almost all membrane-based systems home-built, there no widely accepted material standards or protocols in literature, making it challenging to accurately compare experimental result...

The settlement rate and pore water pressure dissipation are mainly controlled by the permeability of soil. Both laboratory field tests show that is varied during loading consolidation process. It known process accompanied decrease in void ratio which leads to coefficient permeability. importance on time needs be investigated.This paper takes into account change studies its effect characteristic...

Abstract: This paper presents the results of experimental determination of fiber bed permeability variation with porosity. Flow measurement experiments were designed to measure fiber mat permeability for fiber beds with various fiber volume fractions. Woven fiberglass, chopped fiberglass, and carbon fiber mats were used as reinforcements. The effects of reinforcement type and porosity on fiber ...

2208 CUNICAL CHEMISTRY, Vol. 39, No. 10, 1993 An altered membrane permeability due to a diffuse ischemic process could have caused the increase in the enzyme activities observed. Increased serum CK and CK-MB activities of this magnitude in the presence of hypethermia may indicate a variable susceptibility of individuals to the effects of hypothermia. These findings may be important in the use o...

We investigate the problem of designing metamaterial structures which operate at very low frequencies. As an example, we consider the case of a DC magnetic cloak, which requires a variable, anisotropic magnetic permeability with both paramagnetic and diamagnetic components. We show that a structure based on superconducting components is the key to diamagnetism at low frequencies, and present a ...

permeability can be directly measured using cores taken from the reservoir in the laboratory. due to high cost associated with coring, cores are available in a limited number of wells in a field. many empirical models, statistical methods, and intelligent techniques were suggested to predict permeability in un-cored wells from easy-to-obtain and frequent data such as wireline logs. the main obj...

In this study, vacuum oxygen plasma was applied to enhance the comfort properties of polyester/cotton (P/C) blend fabric (65/35%) for tropical climatic conditions. addition, air and argon were used examine aging effect by TEGEWA drop test. Taguchi method employed design experiment analyze largest influential variable as well optimal parameter levels. More attention given evaluation wickability,...
