[1] We present a model for the study of the effect of rheological hysteresis on compaction in sedimentary basins, when surface loading and unloading occurs. When compaction is slow (sedimentation rate is large and/or permeability is small), the hysteresis has little effect on the basal compaction layer, but in the more realistic case where compaction is fast (i.e., sedimentation is slow and/or ...

In some of the challenging digital rock applications trade-off between model resolution and representative elemental volume is not captured in a single satisfying minimum requirements for both aspects. wide range lithofacies found carbonate reservoir rocks, facies fall this category, where large pores, ooids or vugs, are connected by small scale porous structures that could have orders magnitud...

CO2-rock wettability is a key parameter which governs CO2 trapping capacities and containment security in the context of geo-sequestration schemes. However, significant uncertainties still exist terms predicting rock at true reservoir conditions. This study thus reports on measurements via independent Nuclear Magnetic Resonance (NMR) experiments sandstone (CO2–brine systems) to quantify Wettabi...

The relative permeabilities of CO2 and brine are important parameters that account for two-phase flow behavior, saturation distribution, injectivity. CO2/brine permeability curves from the literature show low endpoint values high residual values. These most distinguishing aspects oil/water gas/oil. In this study, aspect is investigated experimentally by employing a wide range injection rates. A...

Present evidence indicates that proteinuria in patients with the nephrotic syndrome is the result of increased permeability of the glomerular capillary walls to proteins, particularly to albumin (1, 2). A rough indication of the permeability to albumin, relative to permeability to water, is provided by the ratio of the concentration of albumin in glomerular fluid to that in plasma. Assuming tha...

The effect of polymer, plasticizer, and surfactant additives on stress development during drying of calcium carbonate particulate coatings was studied using a controlled-environment apparatus that simultaneously monitors drying stress, weight loss, and relative humidity. We found that the calcium carbonate coatings display a drying stress evolution typical of granular films, which is characteri...

The integrity of the capillary membrane is essential to the maintenance of the circulation in a normal animal. Increased loss of plasma colloids through the capillary wall may be an important factor in the development of a pathologic state. In recent years, interest has centered upon abnormal capillary permeability, and local changes in permeability have been demonstrated in areas of trauma and...

BACKGROUND AND PURPOSE Increased angiogenesis in head and neck squamous cell carcinoma correlates to more aggressive tumors with increased morbidity. Because both elevated blood flow and high serum CXCL8 levels are correlated with increased angiogenesis, our objective was to see if elevated blood flow measured with CT perfusion correlated with CXCL8 levels, thereby helping to identify candidate...

salix integra thunb. is a shrub distributed in china along the huai river riparian zone, and plays an important role in water and soil conservation. s. integra shrub land is easily submerged during july to october due to the flooding of huai river. in order to characterize the physiological mechanisms of waterlogging tolerance of s. integra and to help rationally select waterlogging-tolerant sp...
