Analysis of Pore -Scale Nonaqueous Phase Liquid Dissolution in Etched Silicon Pore Network
… these mass transfer coefficients varied with pore and NAPL blob geometry. Specifically, the mass transfer coefficient decreased with increasing blob size because larger blobs had more NAPL-water interfacial area not adjacent to flowing water, and with decreasing pore throat width to pore …

SEISMIC SIGNATURES OF PORE CONNECTIVITY
… influence on seismic signatures, especially pore connectivity. Firstly, I use the Zoeppritz equation to analyze reflection coefficient's sensitivity to eight medium parameters; results show they all have significantly different sensitivity. Friability is an empirical parameter introduced in …

Delineating the Steps of BAX Pore Activation
… conformational changes to oligomerize and form pores in membranes. Previously unresolved was the basis for the outer cell membranes' escape from BAX poration during apoptosis. Unlike outer cell membranes, which are roughly 40% cholesterol, mitochondrial outer membranes are only 5-10% …

Structure and Organization of Nuclear Pore Proteins
<p>The nuclear pore complex (NPC) is a large macromolecular assembly that controls the flow of molecules between the nucleus and the cytoplasm. Elucidating the structure and organization of this complex will be crucial to understanding the mechanism of nucleocytoplasmic transport, but due to its …

The Nuclear Pore Complex: Novel Glycoprotein Constituents
<p>Nuclear pore complexes are large, uniform organelles with a mass estimated to be on the order of 10<sup>8</sup> daltons. They are ubiquitous components of the nuclear envelope, providing a channel through which macromolecular transport between the nucleus and cytoplasm occurs. Thus far, almost …

MODELLING PORE-LEVEL PROPERTIES OF POROUS MATERIALS
Pore-Cor is a 1.2 Mbyte Fortran 77 software package, which uses information from mercury porosimetry curves, supported by image-analysed electron micrographs, to generate a three-dimensional representational model of the pore-space within a porous material. As a result of this project, a …

Pore-water pressure accumulation under dynamic loadings
… analyses were conducted and the level of excess pore-water pressure accumulated during closely spaced earthquakes was investigated. Results of laboratory triaxial compression tests, drained, undrained, and cyclic direct simple shear tests on loose sandy tailings were used to calibrate the soil …

Prediction of velocity distribution from the statistics of pore structure in 3D porous media via high-fidelity pore-scale simulation
… velocity distribution with the statistics of pore structure in 3D porous media have not been established yet. High velocities are controlled by the formation of channels, while low velocities are dominated by stagnation zones. Recent studies have proposed phenomenological models for the …

Pore Scale Simulation of Transport in Porous Media
… zones, which may result e.g. from dead-end pores or pores perpendicular to the direction of the flow. A program to simulate transport in porous media was developed and verified using several test-problems. An example calculation with a randomly generated porous medium was performed. The …

Extracting Physically Realistic Pore Network Features from XCT Data and Investigating the Impact of Pore Topology on Flow in Porous Media
… transport properties via image processing and pore scale simulations through XCT image data sets of porous media. This study also shows how XCT imaging, coupled with pore topological and morphological measures can be utilized in quantifying the differences, and/or similarities between a 2.5D …

Permeability, Pore Body, and Pore Throat Size Distributions from 2D Image Analysis: Comparison with Results from 3D Imaging and Laboratory Measurements
… based only on porosity segmentation. We estimate pore body and pore throat size distributions, and specific surface area from 2D-images. Then compare those estimates of pore body and pore throat size distributions from thin section to those obtained from 3D imaging, Nuclear Magnetic Resonance …
