It was found previously that the sieving coefficients of Ficoll and Ficoll sulfate across isolated glomerular basement membrane (GBM) were greatly elevated when BSA was present at physiological levels, and it was suggested that most of this increase might have been the result of steric interactions between BSA and the tracers (5). To test this hypothesis, we extended the theory for the sieving ...

In this study, we make use of a nonstationary stochastic theory in studying solute flux through spatially nonstationary flows in porous media. The nonstationarity of flow stems from various sources, such as multi-scale, nonstationary medium features and complex hydraulic boundary conditions. These flow nonstationarities are beyond the applicable range of the ‘classical’ stochastic theory for st...

We quantitatively interpret the recently discovered intriguing phenomenon related to resonance Hyper-Raman (HR) scattering. In resonance HR spectra of all-trans-β-carotene (β-carotene) in solution, vibrations of proximate solvent molecules are observed concomitantly with the solute β-carotene HR bands. It has been shown that these solvent bands are subject to marked intensity enhancements by mo...

A column containing four concentric layers of progressively finer-grained glass beads (graded column) was used to study the transport of the bacteriophage T7 in water flowing parallel to layering through a fining-upwards (FU) sedimentary structure. By passing a pulse of T7, and a conservative solute tracer upwards through a column packed with a single bead size (uniform column), the capacity of...

Norwich’s Entropy Theory of Perception reveals a startling conclusion: that Stevens’ Law with an Index of 1, a power function stating direct proportionality between perceived taste intensity and stimulus concentration, arises purely from theory. Norwich’s theorizing starts with extraordinary hypotheses. First, “multiple, parallel receptor-neuron units” without collaterals “carry essentially the...

Hamad, F. and Mansoori, G.A., 1993. Theory of infinite dilution chemical potential. Fluid Phase Equilibria, 85: 141151. Exact expressions for the infinite dilution chemical potential in terms of the pair correlation function are derived. Appropriate approximations are introduced in these expressions to derive simple equations for the infinite dilution chemical potential in terms of molecular si...

The osmotic dehydration causes water removing from food and also a soluble solid uptake into thefoodstuffs. However, large penetration of solute into the food becomes a major problem in osmoticdehydration.Pre-coating the food to be dehydrated with an artificial, edible barrier was also explored as a wayto efficiently hinder solute penetration. In this study the effect of edible coating (CMC),co...

A method for calculating the nuclear magnetic shielding constant of atoms in solution is proposed based on the ab initio electronic structure theory combined with the extended reference interaction site model in statistical mechanics for molecular liquids. The method is applied to a water molecule solvated in water, acetone, chloroform, and carbon tetrachloride. The results for solvation effect...
