A difference in salt concentration in two solutions separated by a membrane leads to an electrical potential difference across the membrane, also without applied current. A literature study is presented on proposed theories for the origin of this membrane potential (ϕm). The most well-known theoretical description is Teorell-Meyer-Sievers (TMS) theory, which we analyze and extend. Experimental ...

game theory is an approach based on mathematics to study social interactions and modeling strategic situations. this theory focuses on decision situations where preferences of decision makers are disputed. existence of strategic position in city also with a conflict of interest or competition makes using game theory to describe the urban management issues, attractive. one of the important contr...

in this paper we investigate a new notion of bases in hilbert spaces and similarto fusion frame theory we introduce fusion bases theory in hilbert spaces. we also introducea new denition of fusion dual sequence associated with a fusion basis and show that theoperators of a fusion dual sequence are continuous projections. next we dene the fusionbiorthogonal sequence, bessel fusion basis, hilbe...

in this article, the crystallization of polyethylene is investigated by the modified weighted density approximation. also, a direct correlation function of polyethylene based on the rism theory is used. the free energy of a polyethylene is calculated using the density functional theory. the crystallization and also the solid and liquid densities of polyethylene are calculated and compared with ...
