Nuclear Physics BThis study is concern to the homothetic symmetry approach to get exact solutions for locally rotationally symmetric (LRS) Bianchi type-I spacetimes within the framework of f(R) gravity, revealing that such spacetimes posses homothetic symmetry of ...

Influence of Relative Permeability Formulations on Hysteretic Seepage in Infinite Slopes
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The paper investigates the impact of two classical relative permeability formulations, one expressed in terms of pore water pressure and the other in terms of degree of saturation, on the predicted seepage in an infinite slope subjected to surface pore pressure variations.

Topological defects in f(T) theory of gravity
European Physical Journal C: Particles and FieldsIn this paper, we investigate the behaviour of domain walls and one-dimensional cosmic string with locally rotationally symmetric (LRS) Bianchi type-I metric in the context of f(T) gravity. Three different types of deceleration parameter (DP) forms, such

Polymer Engineering &Science, EarlyView.Thermokinetic processing controls graphene fragmentation and dispersion in HDPE, promoting heterogeneous nucleation and multistep crystallization. The balance between nucleation enhancement and chain mobility restriction governs the final crystalline structure and material performance.

Weighing the curvature invariants
European Physical Journal C: Particles and FieldsWe prove several inequalities between the curvature invariants, which impose constraints on curvature singularities. Some of the inequalities hold for a family of spacetimes which include static, Friedmann–Lemaître–Robertson–Walker, and Bianchi type I ...

MASSIVE SCALAR FIELD IN BIANCHI TYPE-V METRIC
, 2015 We have considered Bianchi type –V space time in the presence of massive scalar field in the frame work of Einstein’s theory. We have derived Einstein’s field equations in the presence of scalar field coupled with mass parameter. Some physical and geometrical properties of the solutions have been discussed by using mathematica software.
