Still now there are no theoretical background for explanation of physical phenomena of ‘spooky action at a distance’ as a quantum superposition of quantum particles. Several experiments shows that speed of this phenomena is at least four orders of magnitude of light speed in vacuum. The classical electromagnetic field theory is based on similarity to the classic dynamic of solid continuum media...

In this paper, we establish a regularity criterion for micropolar fluid flows in terms of the one component velocity critical Morrey-Campanato space. More precisely, show that if ...<?, where 0<r<9/10 then weak solution (u,w) is regular.

An analysis study is presented to study the effects of Hall current and Soret effect on unsteady hydromagnetic natural convection of a micropolar fluid in a rotating frame of reference with slip-flow regime. A uniform magnetic field acts perpendicularly to the porous surface which absorbs the micropolar fluid with variable suction velocity. The effects of heat absorption, chemical reaction, and...

The current work deals with the pulsating flow of Au-blood micropolar nanofluid existence thermal radiation and Joule heating. Micropolar fluid is addressed as blood (base fluid) Au (gold) a nanoparticle. has been mathematically modeled, resulting in delicate system partial differential equations (PDEs). A perturbation technique used to convert PDE into ordinary (ODEs), which are subsequently s...

In this paper, the problem of heat and mass transfer on the flow of non-Newtonian micropolar fluid with uniform suction/blowing, heat generation, radiation, thermophoresis and chemical reaction is presented and discussed. The Homotopy Analysis Method (HAM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing the problem. The effects...

The present paper deals with the study of fluid flow and heat transfer characteristics occurring during the melting process due to a stretching surface in micropolar fluid with thermal radiation. A uniform magnetic field is applied normal to surface. The governing equations representing fluid flow have been transformed into nonlinear ordinary differential equations using similarity transformati...

The steady flow of a micropolar fluid, due to a stretching cylinder, is considered. The equations of motion are reduced to a system of ordinary differential equations, which in turn are solved numerically using SOR iterative procedure and Simpson's (1/3) rule, for three different combinations of the three dimensionless parameters involved. Results are calculated, for the range 0.1 to 100 of the...

We have studied lattice dynamic properties of SrTiO3 thin films from 5 to 300 K using metaloxide bilayer Raman scattering. First-order zone-center optical phonons, symmetry forbidden in single crystals, have been observed in the thin films, indicating strain-induced lowering of symmetry. The asymmetric line shape of the TO2 phonon is interpreted as evidence for micropolar regions in the thin fi...
