Dark energy with the usually used equation of state p = wρ, where w = const < 0 is hydrodynamically unstable. To overcome this drawback we consider the cosmology of a perfect fluid with a linear equation of state of a more general form p = α(ρ−ρ 0), where the constants α and ρ 0 are free parameters. This non-homogeneous linear equation of state provides the description of both hydrodynamically ...

High-energy heavy-ion collisions generate extremely strong magnetic field which plays a key role in number of novel quantum phenomena quark-gluon plasma (QGP), such as the chiral effect (CME). However, due to complexity theoretical modellings coupled electromagnetic fields and QGP system, especially pre-equilibrium stages, lifetime medium remains undetermined. We establish, for first time, kine...

We have investigated effects of excluded volume interactions on the translational diffusion of hydrodynamically anisotropic molecules. For that, we have performed rigid-body Brownian dynamics simulations of aqueous solutions of hen egg-white lysozyme (HEWL), at concentrations ranging from 1.25 mg/mL to 250 mg/mL and evaluated the lysozyme's self-diffusion. In the long time limit (above 1 μs), t...

universities have a magnificent role in the sustainable development of their country and international scientific production of their country. purpose of this paper is expansion of using balance scorecard in universities in order to improve performance of universities in learning and educating. the balanced scorecard (bsc) is an extensively adopted performance management framework in a lot of o...
