TL;DR: In this article, the compositional dependence of some physical properties such as: density, dc conductivity and thermal conductivity, have been investigated and the effects of composition, temperature and time of annealing are explained in terms of structural changes and crystallization kinetics.
Abstract: This paper reviews some work done in our laboratory on the binary amorphous system Se−Te. The compositional dependence of some physical properties such as: density, dc conductivity and thermal conductivity, have been investigated. A number of results are reviewd. The effects of composition, temperature and time of annealing on the dc conductivity are explained in terms of structural changes and crystallization kinetics. The spectrum of the activation energies of crystallization for the amorphous solid and liquid phases is discussed.

TL;DR: In this paper, the basic physical assumptions and results of Landau's hydrodynamic model of particle production are reviewed and it is argued that these results have sufficient descriptive and predictive power in strong-interaction phenomenology, including recent RHIC data, to warrant a closer examination of the physical assumptions.

TL;DR: In this paper, the effect of viscosity variation on the flow of blood during deep heat muscle treatment is studied and two methods: an asymptotic series expansion technique and a perturbation technique are employed to obtain the temperature distribution.
Abstract: The effect of viscosity variation on the flow of blood during deep heat muscle treatment is studied. Two methods: an asymptotic series expansion technique and a perturbation technique are employed to obtain the temperature distribution. The results are compared with the problem of Part I. A novel development in this part of the study is the combined asymptotic patching and matching technique.

TL;DR: For the class of all discrete two-velocity models of the nonlinear Boltzmann equation consistent with the H-theorem, an exact representation of the corresponding nonlinear constitutive equation was derived in this article.
Abstract: For the class of all discrete two-velocity models of the nonlinear Boltzmann equation consistent with theH-theorem an exact representation of the corresponding nonlinear constitutive equation will be derived. Applying the fractional calculus we derive, in addition, the nonlinear fractional Boltzmann equation as the starting point for the formulation of a nonlinear fractional constitutive equation which relates the densities and fluxes through an integro-differential equation. Linearization leads to the fractional version of Cattaneo's constitutive law. The model presented here may be regarded as a first step, towards the formulation of a fractional extended irreversible thermodynamics.
