Abstract :

We have investigated Bianchi type III string cosmological model with bulk viscosity and without time depending  term. To obtain a determinate solution, it is assumed that coefficient of bulk viscosity is proportional to shear scalar . The physical and geometrical features are also discussed.

Keyword : Bianchi type III, Cosmic string, Bulk viscosity,space time.

Abstract :

In this article, an influence of slip and joule heating on MHD peristaltic blood flow with uniform porous medium through an inclined asymmetric vertical tapered channel in the presence of radiation -blood flow model have been investigated. The impact of all the physical parameters is plotted for velocity profile, pressure gradient, temperature and heat transfer coefficient. It is notice that the axial velocity increases with increase in M, β, η and α. We observe that the pressure gradient enhances with increase in M, β, η and α. However reverse situation is observed for an increase in the values of porous parameter (Da) andVolumetric flow rate (Q). Further, we notice that the temperaturedistribution increases with increase in M, Pr, Da, N, γ and Br and alsotemperature distribution decreases with increase in β and η.

Keyword : MHD, Joule heating, radiation, porous medium and Inclined channel.

Abstract :

The aim of the present attempt was to investigate ananalysis of joule heating and radiation on hydromagnetic peristalticflow with porous medium through a coaxial asymmetric vertical inclined tapered channel. The Mathematical modeling is investigated by utilizing long wavelength and low Reynolds number assumptions. Analytical solutions are obtained for the axial velocity, pressure gradient, temperature and heat transfer coefficient. The effects of Hartmann number, porosity parameter, volumetric flow rate, radiation parameter, non- uniform parameter, gravitational parameter, shift angle, Prandtl number, Brinkman number, heat source/sink parameter on axial velocity characteristics, pressure gradient characteristics, temperature characteristics and heat transfer coefficient characteristics are presented graphically and discussed in detail.

Keyword : Joule heating, radiation parameter, inclined channel, tapered channel, MHD.

Abstract :

In this paper, we introduce and establish some new separation axioms using the --open sets, -semi-open sets, -
pre-open sets in extended bitopological ultra spaces called as - Ri, -Semi-Ri (i=0,1), -RD, -RT, and -RYS
spaces. We also investigate some of their basic properties and establish the relationship between them.
