The approach of generalized collective modes is applied to the study of dispersion curves of collective excitations along isothermal lines of supercritical pure Lennard-Jones fluid. An effect of structural relaxation and other nonhydrodynamic relaxation processes on the dispersion law is discussed. A simple analytical expression for the dispersion law in the long-wavelength region of acoustic e...

Interaction of Schiff base complexes of Iron and Manganese: Iron [N, N’ Bis (5(triphenyl phosphonium methyl) salicylidene) -1, 2 ethanediamine) chloride, [Fe Salen]Cl; Manganese [N, N’ Bis (5(triphenyl phosphonium methyl) salicylidene) -1, 2 ethanediamine) acetate, were investigated by spectroscopic and isothermal titration calorimetry techniques (ITC). The absorbance spectra of complexes have ...

The stability of orange juice obtained from a small extractor and stored in a polyethylene bottle was assessed under isothermal and non-isothermal storage conditions at 4, 8 and 12C for 72 hours. pH, titratable acidity and Brix did not alter significantly during the 72 hours storage. Microbiological analysis showed high initial count for moulds and yeasts that increased in the juice stored for ...

The Rensselaer Isothermal Dendritic Growth Experiment (RIDGE) is a continuation of the Isolated Dendritic Growth Experiment (IDGE), which flew on three space flight experiments aboard the space shuttle Columbia. The RIDGE is an extension to the completed flight experiments by IDGE, to further investigate phenomenon uncovered in the analysis of data obtained by these earlier efforts. The first t...

This paper is devoted to the study of mathematical problems arising in the modelling of nonisothermal polymer crystallization under industrial conditions. A review of the hybrid stochastic-deterministic modelling procedure, which yields an averaged model 5;8 , is given and supplied by the study of mathematical problems arising from it. Furthermore, multiple scale eeects in the crystallization p...

Due to the isotropy and high thermal conductivity of metal foam, a novel idea isothermal chamber filled with graded copper foam (GCF) is developed improve characteristic chamber. Firstly, an analytical effective (ETC) prediction model proposed, relative root-mean-square error (RRMSE) 6.90%, which has higher ETC accuracy than semi-empirical models in literatures. Secondly, conventional porous ra...

Recent studies on Cu interconnects have shown that interface diffusion between Cu and the cap layer dominates mass transport for electromigration. The kinetics of mass transport by interface diffusion strongly depends on the material and processing of the cap layer. In this series of two papers, we report in Part I the interface and grain-boundary mass transport measured from isothermal stress ...

A Monte Carlo algorithm to simulate the isothermal recrystallization process of snow is presented. The snow metamorphism is approximated by two mass redistribution processes: surface diffusion and sublimation-deposition. The algorithm is justified and its parametrization is determined. The simulation results are compared to experimental data, in particular, the temporal evolution of the specifi...
