A statistical associating fluid theory to model electrolyte fluids that explicitly accounts for solvent molecules by modeling water as a dipolar square-well associating fluid is presented. Specifically the statistical associating fluid theory for potentials of variable range (SAFT-VR) is combined with integral equation theory and the generalized mean spherical approximation using the nonprimiti...

Deshpande & Rankin (1999, 2001) claim that the frequency of the very narrow feature, in the spectrum of radio flux variations of PSR B0943+10, is an alias of its actual value. For this, they need to interpret the narrow feature as a very stable pattern of drifting sub pulses on the polar cap of this pulsar, within the framework of the Ruderman & Sutherland (1975) model. This paper discusses sev...

A Born–Green–Yvon integral equation approach is used to study the structure and phase behavior of a fluid of fused square-well-sphere dimers. We compute site–site distribution functions for dimers with bond lengths of L50.6s , 0.8s, and 1.0s ~where s is the hard-sphere diameter! and square-well diameters ranging from l51.25s to 2.0s over a wide range of temperature and density, and make compari...

We give a sharp divisibility bound, in terms of g, for the degree of the field extension required to realize the endomorphisms of an abelian variety of dimension g over an arbitrary number field; this refines a result of Silverberg. This follows from a stronger result giving the same bound for the order of the component group of the Sato–Tate group of the abelian variety, which had been proved ...

A non-stationary polar gap model first proposed by Ruderman & Sutherland (1975) is modified and applied to spark–associated pulsar emission at radio wavelengths. It is argued that under physical and geometrical conditions prevailing above pulsar polar cap, highly non-stationary spark discharges do not occur at random positions. Instead, sparks should tend to operate in well determined preferred...
