the third order term in the density functional is required for study of an inhomogeneous fluid. this term can be chosen such that, the thermodynamic potential gives the correct bulk pressure. the density porofile of a hard sphere fluid near hard wall which is an inhomogeneous fluid is obtained and it is shown that, if the third order term is ignored, although an exact bulk direct correlation fu...

We present an analytic approach to predict gas density and temperature profiles in dark matter haloes. We assume that the gas density profile traces the dark matter profile in outer parts of the haloes, as suggested by a number of hydrodynamic simulations. Under this assumption the hydrostatic equilibrium uniquely fixes the two free parameters in the model, the mass– temperature normalization a...

Themesoscopic properties of a plasma in a cylindrical magnetic field are investigated from the view point of test-particle dynamics. When the system has enough time and spatial symmetries, a Hamiltonian of a test particle is completely integrable and can be reduced to a single degree of freedomHamiltonian for each initial state. The reduced Hamiltonian sometimes has an unstable fixed point (sad...

introduction: abnormal lipid profile causes maternal mortality and impairs fetal development. this study investigated the effect of ramadan fasting on plasma lipid profile in pregnant women. material and methods: this self-control, cohort study was performed in healthy volunteer fasted pregnant women. serum cholesterol, triglyceride (tg), low density lipoprotein (ldl), high density lipoprotein ...
