the virial coefficients can be obtained from statistical mechanics in connection with the intermolecular potentials. the intermolecular potential of polyatomic molecules is usually assumed to consist of a spherically symmetric component plus a contribution due to asphericaity of the molecular charge distribution. in this study, the second virial coefficients have been calculated for n2, co and ...

To evaluate the effect of diffusion on the pulmonary extravascular water volume determined from indicator dilution studies, simultaneous comparisons of the pulmonary extravascular distribution volumes of tritiated water (THO) and of three lipid soluble substances with higher molecular weights were made. In 21 studies on pentobarbital-anesthetized dogs, the distribution volume of antipyrine (AP)...

We present a lower bound on the Jensen-Shannon divergence by the Jeffrers’ divergence when pi ≥ qi is satisfied. In the original Lin's paper [IEEE Trans. Info. Theory, 37, 145 (1991)], where the divergence was introduced, the upper bound in terms of the Jeffreys was the quarter of it. In view of a recent shaper one reported by Crooks, we present a discussion on upper bounds by transcendental fu...

Antidepressants, especially amitriptyline, are among themost frequent drug classes involved in intoxications. Despite its small molecular weight, amitriptyline is not considered to be eliminated by extracorporeal treatmentmethods due to its high protein binding and large volume of distribution. New high cut-off dialysers have so far not been used for removal of amitriptyline. We report two case...

Biological membranes are composed of a thermally disordered lipid matrix and therefore require non-crystallographic scattering approaches for structural characterization with x-rays or neutrons. Here we develop a continuous distribution (CD) model to refine neutron or x-ray reflectivity data from complex architectures of organic molecules. The new model is a flexible implementation of the compo...

The influence of localized water currents on the nonlinear dynamics and stability of large amplitude, statistically distributed gravity waves is investigated theoretically and numerically by means of an evolution equation for a Wigner function governing the spectrum of waves. It is shown that water waves propagating in the opposite direction of a localized current channel can be trapped in the ...

background: cutaneous leishmaniasis constitutes a major public health problem in many parts of the world including iran. the primary objective of this study was to identify leishmania spe­cies in endemic districts of kerman province, south-eastern iran . methods: this study was conducted by random sampling as cross- sectional descriptive between 2008 and 2010. overall, 203 skin scraping smears ...

The melting of a 64 ion microcrystal of KCI was studied by means of a molecular dynamics computer simulation. We used a central pair interaction with an inverse power law repulsion. The thermodynamics, kinetic and structural properties such as melting temperature, latent heat, mean square displacement, diffusion constant, radial distribution function and bond angle distribution are calculated. ...
