β¦ Synopsis
For a skew field extension L/K, a number of intermediate fields can be defined on the basis of the centralizer of K in L. In this paper such intermediate fields are studied in detail. Among the results are a standard decomposition of any skew field extension of finite degree and four types of skew field extensions that are basic to such a standard decomposition. A number of persistence properties of these types are explored.  2002 Elsevier Science (USA)

## Abstract A simple theory is developed for the extension of a uniformly charged linear polyion attached at one end in an electric field. For a polyion consisting of a very large number (__N__) of Kuhn lengths (__b__), the mean extension in the direction of the electric field (__E__) is given accu
## Abstract The theoretical calculation about the dependence of the ionic current density across the cellular membrane on the intensity of the magnetic field applied to cellular tissue is presented. This interaction induces changes in the magnitude of the ionic current density across the cellular m
