The screening of a He+ ion embedded in a paramagnetic electron gas is studied using density functional theory within the local spin density approximation. We calculate the induced electron density and the induced density of states for each spin orientation, parallel and antiparallel to that of the electron bound to the He+ ion. Our results show that the screening is preferably due to parallel s...

The relationship between language and thinking the effect of these two skills on each other is accepted by field experts, but level still a matter debate. In this research, some part thought has been dwelled upon. aim research to determine 7th grade students' reading, listening comprehension creative levels; reading skills. data study, which descriptive study in relational screening model, was ...

AbstracG-The hydrodynamic boundary condition at the interface between a porous and a plain medium is examined by direct simulation of the two-dimensional flow field near the interface of a porous medium made of cylinders. The existing slip boundary condition, which contains a slip coefficient a, and the noslip boundary condition, which contains an effective viscosity p’, are examined. The depen...
