Bogoliubov-de Gennes (BdG) Hamiltonian for electron-Hole superconductors

Kiboi D. Chenge, Limo C. Samuel, Kapil M. Khanna

World Scientific News > 2022 > 172 > 43-54

The Bogoliubov-de Gennes (BdG) Hamiltonian is presented for electron-hole superconductors with reference to YBCO having an energy gap Δm ≈ 25 meV. Metals and metallic alloys are assumed to be composed of free electron gas at room temperatures. At very low temperatures in the superconducting state, the electrons occupy a sea of levels, called Fermi sea, up to the top of the level called Fermi level...

Finite Element Thermal Analysis of Electronic Heat Sinks of Convex and Concave Parabolic Porous Fins with Temperature-dependent Thermal Properties and Internal Heat Generation

M. G. Sobamowo, T. O. C. Agbelusi, M. O. Salami

World Scientific News > 2022 > 172 > 1-19

Electronic heat sinks are made of convex and concave parabolic fins due to their light weights which is an important factor in the design of the medical devices. The actual design of these fins depends on the proper analysis of the temperature distribution and the heat transfer in the extended surfaces. Therefore, the present work focuses on the thermal analysis of convective-radiative porous convex...

Agro-morphological characterization and evaluation of okra [Abelmoschus esculentus (L.) Moench] landraces for yield and association among traits at Pawe, Northwest Ethiopia

Flagote Alemu

World Scientific News > 2022 > 172 > 20-42

Okra is a traditional vegetable crop in northwestern Ethiopia but it has not given research attention and considered a minor crop. Thus, this study was conducted to characterize and evaluate okra landraces and to estimate genotypic, phenotypic variability and genetic divergence and to estimate heritability and genetic advance under selection, degree of genotypic and phenotypic associations among yield...
