Structural, electronic, elastic and dynamic properties of Li2TlIn were studied for the ground state (i. e. P = 0 kbar) under pressure value 4.53 kbar, using Density Functional Theory (DFT). The electronic band density states (DOS) calculations reveal that crystal is in a metallic structure. Focusing on has shown this compound ductile mechanically stable material both kbar. In addition, phonon d...

In this study we introduce a new tensor in semi-Riemannian manifold, named the M*-projective curvature which generalizes m-projective tensor. We start by deducing some fundamental geometric properties of After that, pseudo symmetric manifolds (PM?S)n. A non-trivial example has been used to show existence such manifold. series interesting conclusions. establish, among other things, that if scala...

Aim of present work is to evaluate the tensile strength, impact and hardness (Novalac/TiO2) composite with (Vf = 12% optimum value volume fraction for calculating properties) prepared by open molding (hand lay-up) technique. Thermal conductivity (k), weight gain % after immersed in NaOH solution 0.5 M 60 days were calculated. 
 Results showed a decreasing mechanical properties different ra...

The structural, electronic, elastic and optic properties of NaYSi formed in the half-Heusler structure are studied by using ab-initio density-functional theory. calculated equilibrium lattice constants compaired with available experimental theoretical data. parameters have calculated. Computed results prove that this compound were mechanically stable. band gap predicted to be semiconductor. Fur...

in this study, some seed physical properties of two sugar beet varieties, shirin and gadouk (436), were evaluated as a function of moisture content. physical properties included length, width, thickness, arithmetic and geometric mean diameters, sphericity, thousand seed weight, angle of repose, terminal velocity, true density, bulk density, porosity, and coefficient of friction. four moisture c...
