This paper investigates unsteady two-dimensional MHD flow past a rotating semi-infinite plate with an inclined magnetic field viscous dissipation, Ohmic and Joule heating. The fluid is assumed to be electrically conducting. governing non-linear partial differential equations for mass, momentum, energy, concentration are transformed into couple system by using appropriate dimensionless parameter...

In this paper, we study complex Wishart processes or the so-called Laguerre processes (Xt)t≥0. We are interested in the behaviour of the eigenvalue process; we derive some useful stochastic differential equations and compute both the infinitesimal generator and the semi-group. We also give absolute-continuity relations between different indices. Finally, we compute the density function of the s...

(compacta) and continuous mappings was founded by Shchepin [Sh]. He described some elementary properties of such functors and defined the notion of the normal functor which has become very fruitful. The classes of all normal and weakly normal functors include many classical constructions: the hyperspace exp, the space of probability measures P, the superextension λ , the space of hyperspaces of...

HE general model proposed by JACOB and MONOD (1961) to explain the control of inducible and repressible enzymes in bacteria has received considerable support to date (AMES and MARTIN 1964). According to this hypothesis, the genetic elements controlling sequential biochemical reactions are clustered on a genetic map into units of regulation called operons. An operon consists of a group of struct...
