[1] Hydraulic tomography is a cost-effective technique for characterizing the heterogeneity of hydraulic parameters in the subsurface. During hydraulic tomography surveys a large number of hydraulic heads (i.e., aquifer responses) are collected from a series of pumping or injection tests in an aquifer. These responses are then used to interpret the spatial distribution of hydraulic parameters o...

INTRODUCTION: The calculation of Manning n values has been of interest since the Manning equation was presented in the late 1800s (Henderson, 1966). While estimation of n vahm for normal channels has been fairly well standardized, the estimation of n values in areas of dense vegetation continues to be subject to large variations depending on the experience of the engineer and the perceived dens...

The success of cell-based tissue engineering approaches in restoring biological function will be facilitated by a comprehensive fundamental knowledge of the temporal evolution of the structure and properties of the newly synthesized matrix. Here, we quantify the dynamic oscillatory mechanical behavior of the engineered matrix associated with individual chondrocytes cultured in vitro for up to 2...

The present work determined the influence of superhydrophobic nano-SiO2 on hydraulic conductivity and pore size distribution expansive soil, analysed mechanism modification between soil from a microscopic view. Superhydrophobic was added to as modifier. Our samples were two types, i.e., unmodified (without nano-SiO2) modified (with 0.2%, 0.4%, 0.6%, 0.8%, 1.0% by weight parent soil). decreased ...

Quantification of the permeability of connective tissue linings isolated from implanted capsules was achieved by two types of experiments. The objective of the first type was to determine the restriction offered by the lining to diffusion of 'I-labeled human serum albumin. The restricted diffusion coefficient of albumin with respect to the connective tissue lining the luminal capsule surface (i...

This paper describes the dimensionless groups that determine the break-up probability of droplets in a concentrated emulsion during its flow in a tapered microchannel consisting of a narrow constriction. Such channel geometry is commonly used in droplet microfluidics to investigate the content of droplets from a concentrated emulsion. In contrast to solid wells in multi-well plates, drops are m...

Gas transport in unconventional shale strata is a multi-mechanism-coupling process that is different from the process observed in conventional reservoirs. In micro fractures which are inborn or induced by hydraulic stimulation, viscous flow dominates. And gas surface diffusion and gas desorption should be further considered in organic nano pores. Also, the Klinkenberg effect should be considere...

This work analyses the applicability of the Lucas–Washburn equation to experimental observations of imbibition into real network structures. The experimental pore structures used in this study are constructed from tablets of two finely ground calcium carbonates, with defined differences in particle size distribution. These are compressed under a range of different applied pressures to achieve a...

Quantification of the permeability of connective tissue linings isolated from implanted capsules was achieved by two types of experiments. The objective of the first type was to determine the restriction offered by the lining to diffusion of 125I-labeled human serum albumin. The restricted diffusion coefficient of albumin with respect to the connective tissue lining the luminal capsule surface ...

We have analyzed glomerular sieving data from humans, rats in vivo, and from isolated perfused rat kidneys (IPK) and present a unifying hypothesis that seems to resolve most of the conflicting results that exist in the literature. Particularly important are the data obtained in the cooled IPK, because they allow a variety of experimental conditions for careful analysis of the glomerular barrier...
