Boltzmann Transport Equation is solved numerically to model phonon transport in a subcontinuum domain in order to study heat transfer in thin film semiconductors. The phonon distribution function is modified to get an Energy equation from the Boltzmann Transport Equation. Gray form of the Energy equation is solved in the Relaxation time approximation to get the Phonon Energy Density distributio...

We determine the relations of power product of physical quantities (PQs) by the generalized relation. Assuming the relations with two, three and four PQs to generalized relation separately, we find the corresponding general formulas. By ordering the exponent of physical constant in relations being zero or fit number, we gain many famous equations without factors such as mass-energy relation, fo...

We investigate the corrections to the inflationary cosmological dynamics due to a R2 term in the Palatini formulation which may arise as quantum corrections to the effective Lagrangian in early universe. We found that the standard Friedmann equation will not be changed when the scalar field is in the potential energy dominated era. However, in the kinetic energy dominated era, the standard Frie...

the extended hildebrand solubility parameter approach (ehsa) is used to estimate the solubility of satranidazole in binary solvent systems. the solubility of satranidazole in various water-peg 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of hildebrand-scatchard treatment for regular solutions. the solubility equation employs term interaction energy ...

Recent progress in theoretical physics suggests that the dark energy in the universe result from the Born-Infeld (B-I) type scalar field of string theory. The universe of B-I type scalar field with potential can undergo a phase of accelerated expansion. The corresponding equation of state parameter lies in the range of −1 < w < − 1 3. The equation of state parameter of B-I type scalar field wit...

The energy route to the equation of state of hard-sphere fluids is ill defined since the internal energy is just that of an ideal gas, and thus it is independent of density. It is shown that this ambiguity can be avoided by considering a square-shoulder interaction and taking the limit of vanishing shoulder width. The resulting hard-sphere equation of state coincides exactly with the one obtain...
