The phenomenological model of Khossravi and Connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. The accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (APMD). The obtained APMD for correlative and predictive studies ...

This paper deals with black holes, bubbles and orbifolds in GaussBonnet theory in five dimensional anti de Sitter space. In particular, we study stable, unstable and metastable phases of black holes from thermodynamical perspective. By comparing bubble and orbifold geometries, we analyse associated instabilities. Assuming AdS/CFT correspondence, we discuss the effects of this higher derivative ...

The optical properties of composite materials are studied theoretically as a function of temperature via a phenomenological model for temperatures up to the melting points of the materials. Both the Maxwell-Garnett and Bruggeman models are considered and the temperature variation of the optical constants of the metallic particles is obtained with an account of the dependence of both the electro...

The change in entropy, DS , at the first-order magnetoelastic phase transition in Gd5(SixGe12x)4 alloys for x<0.5 has been measured with a high-sensitivity differential scanning calorimeter with built-in magnetic field, H. Scaling of DS is achieved by changing the transition temperature, Tt , with x and H from 70 to 310 K. Tt is thus the relevant parameter in determining the giant magnetocalori...
