We have studied stability of lithium-manganese oxides using density functional theory in the local density and generalized gradient approximation ~GGA!. In particular, the effect of spin-polarizationâ€¦ (More)

Abstract The hysteresis (Â»j) of the non-dimensional site-specific rating curve is used to describe the occurrence of a kinematic wave (KW), a diffusion wave (DW) or a dynamic wave (DYW) in theâ€¦ (More)

The steady boundary layer free convective flow of a dusty fluid past a vertical permeable stretching surface is studied .The governing equations are converted into first order ordinary differentialâ€¦ (More)

This paper presents a theoretical model for the propagation of a hollow Gaussian electromagnetic beam [HGB], propagating in a plasma with dominant relativistic-ponderomotive nonlinearity. A paraxialâ€¦ (More)

This paper pertains to investigate the heat transfer characteristics of two dimensional two phase flow in a porous medium over a stretching sheet with internal heat generation. The novelty of theâ€¦ (More)

We report the observation of a Skyrmion lattice in the chiral multiferroic insulator Cu2OSeO3 using Cu L3-edge resonant soft x-ray diffraction. We observe the unexpected existence of two distinctâ€¦ (More)

LiMnO2 is one of only a few ternary oxides which are known to form in the orthorhombic Pmmnstructure. The layered Î±-NaFeO2 structure, favored for application as a Li-insertion electrode, is found inâ€¦ (More)

The Seddon speed formula expressed mathematically as c = dg/dA (or alternatively, as c = (1 + m)u0; where Q is the discharge, A is the area of cross-section, c is the wave speed, u0 is the normalâ€¦ (More)
