In this article we investigate the relation between the temperature and density of the dark energy. We find that the temperature of the dark universe is proportional to the inverse of dark energy density. Also we discuss some values of the important parameters of the theory. © 2010 Springer Science+Business Media, LLC. Source

In this article we consider the cosmological model based on the holographic dark energy. We study dark energy density in Universe with arbitrary spatially curvature described by the Friedmann-Robertson-Walker metric. We use Chevallier-Polarski-Linder parametrization to specify dark energy density. © 2011 Springer Science+Business Media, LLC. Source

Journal of Supercritical Fluids | Year: 2015

The solubility and bioavailability of pharmaceutical compounds are increased via size reduction. The conventional size reduction methods have some disadvantages. The pharmaceutical micronization with supercritical fluids (SCFs) techniques has been proposed. These methods overcome the disadvantages of conventional methods. Therefore, in this work, literature data analysis on the supercritical fluid micronization has been reviewed. The SC carbon dioxide is usually proposed. Micronization with supercritical fluids is classified based on the role of supercritical fluid in a process. Application of these methods for the pharmaceutical micronization has attracted interest in recent year because the micronized particles with narrow particle size distribution and no organic solvent are produced. These methods are rapid expansion of supercritical solutions (RESS) process, gas antisolvent (GAS) process, supercritical antisolvent (SAS) process, solution enhanced dispersion by supercritical (SEDS) process, aerosol solvent extraction system (ASES), supercritical fluid extraction of emulsions (SFEE), and particle from gas saturated solution (PGSS) process. © 2015 Elsevier B.V.

In this paper we consider FRW bulk viscous cosmology in arbitrary space curvature. We extend recent work to the case of non-flat universe in arbitrary space dimension. We obtain Hubble expansion parameter for special cases and study bulk viscous coefficient and deceleration parameter. © 2011 Springer Science+Business Media, LLC. Source

In this paper we consider an interesting model of superfluid and use AdS/CFT correspondence to extract sound modes. We assume that dual picture of superfluid is the R-charged black hole with two equal charges. By using hydrodynamic variables of such a black hole we obtain first, second and fourth sound modes as a function of black hole charge. © 2012 Springer Science+Business Media, LLC. Source
