A Model of Magnetoviscous Fluid in General Relativity

abstract

A model of magnetoviscous fluid has been derived which is of non-degenerate Petrov type I. The model for viscous fluid, magnetofluid and perfect fluid have also been obtained in particular cases. Various physical and geometrical properties of the model have been discussed.


A Note on Geometry of the New Cosmology

abstract

The metric of the cosmological model implied by the nonsymmetric unified field theory is transformed to a simpler and more manageable form. Embedding of the metric in a six dimensional fiat manifold is given.


Internal Fields of the Lyttleton–Bondi Sphere

abstract

We obtain a solution of the relativistic field equations for a static Lyttleton–Bondi sphere. We establish the following results: a static Lyttleton–Bondi sphere is a charged dust. In particular we demonstrate that under certain conditions, the sphere cannot exist.


High-Energy Muon-Pair Production and the Drell–Yan Model

abstract

New results from some high statistics experiments measuring muon-pair production in proton- and pion-induced reactions are discussed.


QCD and Spectroscopy

abstract

The bearing of QCD on spectroscopy is illustrated by a discussion of the following topics: the parameters of QCD, QCD Sum Rules, QCD and Current Algebra.
