The present paper aims at investigating the applicability of hybrid cells in the series model for pollution transport inside the layered porous media. For this purpose, four layers of rock material have fallen inside the experimental flume, with eight sensors installed longitudinally inside the media to obtain experimental BTCs. In order to measure time parameters of the model, named , two diff...

Accumulation of sediment transport volume and reduce the useful life of dams, water storage tanks can be. So far, many methods for calculating sediment this is presented in reservoirs are generally classified into two categories: mathematical modeling and experimental .This study examines the effect of using Gstars model parameters in the model, deposition of sediment in the reservoir tank and ...

The oxidative stress responsive kinase 1 (OSR1) contributes to WNK (with no K)-dependent regulation of renal tubular salt transport, renal salt excretion, and blood pressure. Little is known, however, about a role of OSR1 in the regulation of intestinal salt transport. The present study thus explored whether OSR1 is expressed in intestinal tissue and whether small intestinal Na(+)/H(+) exchange...

Na transport across a preparation of sheep omasum was studied. All tissues exhibited a serosa-positive short-circuit current ( I sc), with a range of 1-4 μeq ⋅ h-1 ⋅ cm-2. A Michaelis-Menten-type kinetic was found between the Na concentration and the I sc(Michaelis-Menten constant for transport of Na = 6.7 mM; maximal transport capacity of Na = 4.16 μeq ⋅ h-1 ⋅ cm-2). Mucosal amiloride (1 mM), ...

Studies have been carried out on human erythrocytes to examine the alterations of K transport induced by swelling or shrinking the cells by osmotic and isosmotic methods. Hypotonic swelling of erythrocytes (relative cell volume, 1.20) resulted in a striking, four- to fivefold augmentation in the ouabain-resistant K influx over the value obtained at a normal cell volume. Shrinking the cells in h...

Providing context-dependent security services is an important challenge in ambient intelligence. The complexity and the unbounded nature of such systems make it difficult for software developers to integrate security solutions. In order to solve this problem, in this paper we discuss and address multifold security challenges involved in the implementation of remote healthcare in smart homes usi...

Active transport of thiamin (vitamin B(1)) into Escherichia coli occurs through a member of the superfamily of transporters known as ATP-binding cassette (ABC) transporters. Although it was demonstrated that the sulfhydryl-specific modifier N-ethylmaleimide (NEM) inhibited thiamin transport, the exact mechanism of this inhibition is unknown. Therefore, we have carried out a kinetic analysis of ...
