In this thesis we have derived the vector potential to determine the analytic expressions for the magnetic eld of dipole and quadrupole components of neutron star, we develop the eld line equations and the magnetic ...

The 2D scattering problem of an electron by a magnetized nanoparticle is solved in the Born approximation with account of the dipole - dipole interaction of the magnetic moments of electron and nanomagnet. The scattering ...

A family of conjugated polymers based on 9,9-disubstituted fluorenes and cyanovinylenes were reported. The polymers were synthesized by employing a slightly modified Suzuki coupling polymerization reaction and condensation ...

Silicon is an ubiquitous electronic material and the discovery of strong room temperature luminescence from porous silicon in 1990 raised hopes it may find a new lease of life in the emerging field of optoelectronics. ...

Despite the current environmental controversies, flower farms are becoming hot areas of investment in Ethiopia. Golden Rose Agro Farm is one of the largest, and the pioneer, flower industries in the country. To study ...

We have used the ab-initio SIESTA code within the framework of DFT, LDA method to calculate the structural and electronic properties of BexZn1-xSe alloy for different compositions x = 0.0, 0.33, 0.66, and 1.0. The system ...

The introduction of new information and communication technologies in libraries during the last two decades has altogether changed the concepts of libraries where library patrons need not necessarily go to the library ...

The Tiliapia fish samples and water samples were collected from Lake Hawassa at three selected sampling sites namely Tikur Wuha, Dorie basana and Referral H. sites. The concentrations of certain heavy metals ( copper ...

Intestinal parasitic infections represent serious medical and public health problems in many developing countries especially in the tropical regions. Taeniasis and cysticercosis have been recognized as important problems ...

The purpose of this research was to look in to the implementation of adapted physical education lesson for students with visual impairment in two selected elementary schools of Addis Ababa. sThe participants of the study ...
