A degenerate perturbation $k\cdot p$ approach for effective mass calculations is implemented in the all-electron density functional theory (DFT) package WIEN2k. The accuracy tested on major group IVA, IIIA-VA, and IIB-VIA semiconductor materials. Then, graphene CuI with defects presented as illustrative applications. For states significant Cu-d character additional local orbitals higher princip...

We treat 0+ → 2+ 0νββ decays taking into account recoil corrections to the nuclear currents. The decay probability can be written as a quadratic form of the effective coupling constants of the right-handed leptonic currents and the effective neutrino mass. We calculate the nuclear matrix elements for the 0+ → 21 0νββ decays of 76Ge and 100Mo, and demonstrate that the relative sensitivities of 0...

frying is an important unit operation used widely both in domestic and industrial cooking. reduced pressure (vacuum), microwave, deep fat and pan frying are the most important methods of food frying. final product has good organoleptic quality (colour, texture, and flavour). the accuracy of the knowledge of mass transfer parameters (effective diffusivity coefficient, dimensionless biot number a...
