An aquaporin (Hyla AQP-h3BL), consisting of 292 amino acid residues, has been cloned from the urinary bladder of Hyla japonica. In a swelling assay using Xenopus oocytes, AQP-h3BL cRNA-injected oocytes developed a sevenfold and 2.8-fold higher permeability to water and glycerol, respectively, than the water-injected oocytes. This permeability was inhibited by HgCl2. Immunofluorescence revealed ...

Two recently cloned water channels, CHIP28 and WCH-CD, are homologous to MIP26, an integral membrane channel-forming protein found in lens fiber plasma membranes. CHIP28 is found in basolateral and apical plasma membranes of kidney proximal tubules and thin descending limbs of Henle, whereas WCH-CD is apically located in collecting duct principal cells. So far, the putative water channel that m...

This study analyzes the effect of corporate governance (CG) quality on principal-agent (PA) and principal-principal (PP) conflict in Indonesia while also controlling for potential endogeneity through use two-stage least squares (2SLS) regression. The results PA (measured by operating expense ratio asset utilization ratio) are consistent with notion that better CG leads to a lower level conflict...

The present paper investigates the influence of stabilization with cement, peat ash, and silica sand on permeability coefficient (kv) of compacted clay, using a novel approach to stabilize the clay with peat ash as a supplementary material of cement in the compacted and stabilized soil. In order to assess the mentioned influence, test specimens of both untreated and stabilized soil have been te...

The prediction of porosity is achieved by using available core and log data; however, the estimation of permeability is limited to the scare core data. Hence, porosity and saturation data through the framework of flow units can be used to make an estimation of reservoir permeability. The purpose of this study is to predict the permeability of a carbonate gas reservoir by using physical-based em...

This paper addressed the application of new hydrophobic synthesized calcium oxide (CaO) and silicon dioxide (SiO2) nanofluids to low permeability carbonate porous media. Crude oil and plugs were selected from one of oil reservoirs in the west of Iran. The main goal of this paper is comparing the results of improving water-oil relative permeability parameters in low permeability plugs...
