In tropical countries like Ethiopia where the wet seasons are restricted to less than five months of the year, wetlands such as those found around Lake Zwai provide ideal environments for water-related diseases of sheep ...

The excitation functions for several residues produced in the system 20Ne+59Co have been studied in the energies range 62.9-150.2 MeV. The experimental excitation functions have been compared with those calculated using ...

The spectral aerosol optical depth measurements are estimated over Addis Ababa (09.033N , 38.7E) at 2445m a.m.s.l. from the measurements of direct solar irradiance at different wavelengthes in the range between 305.3-1020nm ...

Excitation function of (a , xn) ) reaction on Ir -191 (abundance 37.3%) and Ir -193 (abundance 62.7%) were studied for various energy range of alpha particle. The calculations were done using ALICE-91 computer code, which ...

CNTs are very thin materials made from carbon by rolling graphene sheets. Arc-discharge, laser ablation and chemical vapor deposition are well established techniques to prepare carbon nanotubes. Mostly purification is ...

In this study, the effects of a moderate variation of macromolecular properties of poly(p-phenylene-ethynylene)-alt-poly(p-phenylene-vinylene)(PPE-PPV) statistical copolymers (AnE-PVstat) on charge transport properties ...

Alternative energy source of the world in the future is organic pholoYoltaic, which is sustainabl e and environmentally friendl y. Among the different organic photovoltaics, the class of bulk hetcrojunclion solar cells ...

This work focuses on the study of co-existence of superconductivity and ferromagnetism in general and in UGe2 superconductor in particular. Starting with a model Hamiltonian for the system and using Green functions ...

Superconductivity and magnetism were previously thought as incompatible until the discovery of some rare earth ternary compounds that shows the coexistence of superconductivity and magnetism. In some of the recently ...
