Solutions made by homogenization of vitreous humor exhibit anomalous viscosity at low shear rates due to interaction between hyaluronic acid and a hydroxyproline-containing material similar to collagen. The latter can be removed by filtration or centrifugation to give a solution whose viscosity is due to hyaluronic acid. On concentration the viscosity of the latter remains independent of shear ...

To understand the range of close-to-classical critical behavior seen in various electrolytes, generalized Debye-Hückel theories (that yield density correlation functions) are applied to the restricted primitive model of equisized hard spheres. The results yield a Landau-Ginzburg free-energy functional for which the Ginzburg criterion can be explicitly evaluated. The predicted scale of crossover...

If we have a chance to understand the QCD bound-state dynamics without resorting to the lattice or to models [1], this is likely to be in the cases of bound systems whose interaction is dominated by the perturbative dynamics. In such cases non-perturbative corrections exist but are small and can be parameterized in terms of local or non-local condensates. In the following I will call such syste...

Possible strong Van der Waals force is searched in the nuclear interaction, whose existence is expected when the fundamental interaction between quarks is strong or superstrong Coulombic type. The relation between the type of the extra singularity at t = 0 of the scattering amplitude and the power of the asymptotic behavior of the long range potential is derived. The square root cusp in the onc...

The effect of a Coulombic coupling on the dynamics of a quantum dot hybridized to leads is determined. The calculation treats the interaction between charge fluctuations on the dot and the dynamically generated image charge in the leads. A formally exact solution is presented for a dot coupled to a Luttinger liquid and an approximate solution, equivalent to treating the lead dynamics within a r...

In this study, the ground state energies of face-centered cubic Hubbard clusters are analyzed using the Lanczos method. Examination of the ground state energy as a function of the number of particle per site n showed an energy minimum for face-centered cubic structures. This energy minimum decreased in n with increasing coulombic interaction parameter U. We found that the ground state energy ha...

Classical treatment of cell attachment by models of filtration or coulombic attraction assumes that attachment of cells to mineral surfaces would be controlled by factors such as response to predation, collision efficiency, or coulombic attraction between the charged groups at the mineral and cell surfaces. In the study reported here, the passive model of attachment was investigated using a nat...

High stable C/S composites are fabricated by a novel high-temperature sulfur infusion into micro-mesoporous carbon method following with solvent cleaning treatment. The C/S composite cathodes show high Coulombic efficiency, long cycling stability and good rate capability in the electrolyte of 1.0 M LiPF6 + EC/DEC (1:1 v/v), for instance, the reversible capacity of the treated C/S-50 (50% S) cat...
