Background: Attention-Deficit Hyperactivity Disorder (ADHD) is a common childhood neuro-rndevelopmental disorder with early onset, affecting 5.4% and 8.7% of African children. Recentrnstudies reveal that 30% to 70% of children continue to experience problems related to ADHD inrnadulthood that cause...
This study is on the place of women in politics with focus on the African Union’s Solemn Declarationrnon Gender Equality in Africa, in terms of the awareness, support for implementation, views of malernparliamentarians about the declaration, factors responsible for poor representation of...
The braking index of a pulsar is expected to be 3 if it slows down under ordinaryrnmagnetic dipole radiation . However, measured braking indices of young as wellrnas old pulsars are experimentally determined to be different from the above value.rnSometimes these get to large positive and negative...
The main objective of this thesis is to analyze contact stress and estimate surface fatigue life in rolling-sliding contact of involute spur gear by finite element method (FEM). To do this three dimensional involute spur gear pair was developed in Solidworks 2012 Premium. This 3D model was imported...
This study, by taking the case of Addis Ababa, the capital of Ethiopia, investigates therneffects of water and sanitation provision on poor women. The study was instigated byrnthe observation that the pressure of inadequate water supply and sanitation provision fallrnmore on the poor than better...
Background; Recently Diabetes mellitus is becoming an important clinical and public healthrnproblem throughout the world. In Ethiopia although it is known that diabetes is becoming one of thernemerging health issue, little is known about its prevention and the different ways of management inrnthe...
Problems due to mechanical position sensor of Permanent Magnet Synchronous Motor during speed control are alleviated by an observer for estimating instantaneous speed and position of the rotor. This needs a high performance speed and position estimator, i.e. Extended Kalman Filter (EKF), for...
The objective of this study is to investigate the effect of material on surface durability of spur gear. Current Analytical methods of calculating gear contact stresses use the contact stresses of spur gear. It’s necessary to develop and to determine appropriate models of contact elements,...
The study has focused on identifying the socio-cultural and economic challenges encountering women living with HIV/AIDS, coping strategies, their basic needs, their roles in the prevention efforts and factors that make women vulnerable to HIV infection. The target population of the study is mainly...

Electoral system design is being recognized as one of the key instruments in democracy inrnchanging votes into seats. In Ethiopia since 1991 various elections have been held, and thernelectoral system in use is the plurality electoral system. The plurality electoral system is a systemrnwhereby, a...
Background: - Decision making at clinical level is the way in which nurses perceived to arrivernat appropriate decisions in practical nursing situations. And these decisions have a direct impactrnon the health status of the patients, poor clinical reasoning skill leads to increasing numbers...
Usually the axial thrust of a rotary kiln has been controlled by a hydraulic thrust device that constantly pushes the kiln up against gravity. However, the life of the device will be deteriorating earlier expected if other mechanisms are ignored to consider incorporating so that magnitude of the...
Ethiopia’s economy has been challenged by frequent food insecurity for decades as a resultrnof many interrelated environmental, socio-economic and political reasons. The increasingrnsevere food insecurity in recent years forced the Ethiopian government to develop the FoodrnSecurity Strategy...
This thesis presents an optimal power generation expansion planning model that considers the growth of fuel prices and its fluctuation, power risks, benefits of carbon-trading in generation expansion decision. The developed model is applied to Ethiopian Electric Power System for ten years in the...
A Comparative analysis has been carried out between thernexperimental excess heat capacity of solid solutions of"N2 andrn''N2 in Ar and Kr due to rotation of the nitrogen molecules, andrnthe existing theoretical models in the temperature range 0.5 torn6 Kelvin. It is shown that the well known...
Background: Infant feeding practice is the important modifiable factor influencing the health ofrnchildren born from HIV-positive mothers. While breastfeeding carries significant health benefitsrnto infants and young children, HIV can be transmitted during breastfeeding from an HIV-rninfected...
Studies on the feeding ecology, habitat use, activity pattern, andrnstructure of the burrow system and population density of the giant moleratsrnwere carried out on Sanetti Plateau, BMNP from March, 2006 to January, 2007rncovering both wet and dry seasons. The consumed plant materials and hay...
The study is designed to explore the status of gender mainstreaming aspects in two general directorates ofrnMinistry of Foreign Affairs (MOFA): Women’s Affairs General Directorates (WAGD) and Economic BusinessrnAffairs General Directorates (EBAGD). Particularly, the study targeted on three...
Composites materials are intended to be used more extensively as an alternative of aluminum structure in aircraft and aerospace applications. This is due to their attractive properties as high strength-to-weight ratio and stiffness-to-weight ratio. Besides that it clarifies the growing interest for...
