Recently Escobedo and Mansoori (AIChE J. 42(5): 1425, 1996) proposed a new expression, originally derived from statistical mechanics, for the surface tension prediction of pure fluids. In this report, the same theory is extended to the case of mixtures of organic liquids with the following expression, σm = [(1-Tr,m) Tr,m exp (0.30066/Tr,m + 0.86442 Tr,m) (P 0,m ρL,m P 0,m ρv,m)] 4 P0,m = { ΣiΣj...

We study dynamical interactions of star-planet binaries with other single stars. We derive analytical cross sections for all possible outcomes and confirm them with numerical scattering experiments. We find that a wide mass ratio in the binary introduces a region in parameter space that is inaccessible to comparable-mass systems, in which the nature of the dynamical interaction is fundamentally...

This paper studies physical aging by computer simulations of a 2:1 Kob-Andersen binary Lennard-Jones mixture, system that is less prone to crystallization than the standard 4:1 composition. Starting from thermal-equilibrium states, time evolution following four quantities monitored up and down jumps in temperature: potential energy, virial, average squared force, Laplacian energy. Despite fact ...

A feature is a part or aspect of a speciication which a user perceives as having a self-contained functional role. In large speciications there are several problems that make the manipulation of features diicult: the part of the speciication describing a feature is widely distributed over the whole speciication, and features may interact in ways that are hard to predict. To overcome these probl...

The acid-base equilibria of glycine have been studied in different aqueous solutions of 1,4-dioxane(0-50 % by v/v) using potentiometric method. In this study, the macro and micro protonationconstants of the amino acid and its tautomeric constant have been determined at 25 °C and constantionic strength 0.1 mol dm-3 (NaCl). The protonation and the tautomeric constants of glycine indifferent binar...
