In this thesis we have studied excitation function of charge transfer reaction in different nuclear mass region. In the study, calculations of the excitation function of 23 11 Na(p, n) 23 12 Mg, 23 11 Na(n, p) 23 10 Ne, ...
The plant Neem (Azadirachta indica) is used traditionally for treatment of various illnesses
in Ethiopia. However, there was paucity of information with regard to antibacterial activity of part
of Neem used. So in our ...
BACKGROUND: Female genital mutilation/cutting is a harmful practice which has effect on female’s wellbeing. However, the practice has continued to prevail in many cultures. Research on the social determinants of
the ...
In this work, alpha ( 4 He) induced reactions on copper nucleus ( 65 29 Cu) in between the energy range 16 MeV up to 35 MeV were studied. The nuclear reaction cross sections for five reactions namely, 65 Cu(α, n) 68 Ga, ...

Background: It has been estimated that the frequency of premenstrual symptoms was quite high (80-99.6%), and in few women, the symptoms were so severe that might interfere their daily activities. Although it has been widely ...
In this thesis we study the squeezing entanglement and statistical properties of the cavity light beams produced by a coherently driven non-degenerate three-level laser with an open cavity and coupled to a two-mode vacuum ...
We analyze the quantum properties of the light generated by a nondegenerate three-level laser in which the three-level atoms available in an open cavity are pumped to the top level by means ofstrong coherent light. We carry ...

Background: Osteoporosis is one of the systemic features of chronic obstructive pulmonary
disease, and its prevalence is assumed to be two -to five -folds higher than in age and sex
matched healthy subjects.
Objective: ...
In this study we have developed the Hamiltonian and trial wave functions for the
triangular quantum well. Then the schroendinger equation is solved analytically and
numerically for determining the ground and excited state ...
In this research paper ,we study the energy eigenvalue and tunneling effect of rectangular double quantum well (RDQW) heterostructures composed of two different semiconductors. The heterostructure is denoted as B/W/B/W/B, ...
The plant derived materials come into use in the contemporary medicine through aboriginal cure in
traditional systems of medicine. Medicinal plants are chief antidote for numerous diseases and have been
used since time ...
Nickel is a metal which is widely distributed in nature; and it is found in animals, plants, and soil. The density functional theory (DFT) simulation tools were employed to investigate energies, magnetization and geometrical ...

Background: Estimated 150 million people worldwide and nearly 17% of the populations
in the developing nations are currently suffering from sleep problems. In Ethiopia, the
magnitude of this problem was not identified ...
Background: Ectopic pregnancy (EP) is abnormal condition in which implantation of the blastocyst
occurs outside the endometrium of the uterus. It is gynecological important, particularly in the
developing world, because ...
The electronic and structural properties of Iron (Fe) were investigated using density functional theory (QUANTUM ESPRESSO). Iron is the main ingredient used to make steel and the crystalline structure is body center cubic ...
Background: Anemia is a clinical abnormality characterized by reduction in hemoglobin concentration
below normal for age, sex, physiological condition and altitude. Most health provider’s in resource poor
settings rely ...
Despite efforts were made to assess the effect of shade on coffee production and quality, there is
lack of profound assessment works which identified optimum shade level on physical and cup
qualities of Arabica coffee ...
In this study the electronic and structural properties of Aluminum (Al) were investigated with respect to density functional theory by using Quantum Espresso Package.The local density approximation (LDA) and the generalized ...
Background: Breech delivery is generally associated with higher perinatal morbidity
and mortality and the optimal mode of delivery continues to be a source of debate.
However, there is paucity of information about the ...
The national average yield of rice is low which is mainly attributed to shortage of improved
varieties. The present study consists of 36 rice genotypes that were evaluated at two locations,
namely Fogera and Pawe with ...
