The present research has been carried out to identify and document the landrace diversity andrnethnobotanical uses of cowpea (Vigna unguiculata (L.) Walp.) (Fabaceae) in three regions ofrnsouthern Ethiopia (Gambella, Oromia, Dire Dawa and SNNPR). Ethnobotanical data wererncollected using...
Supply of adequate amount of water is one of the main challenges facing people that live in Addis Ababa in addition to water quality problems. Currently, it is becoming clear that developing new ground and surface water sources will not be enough to meet these challenges; it is therefore essential...
Background: -Patients with hypertension are at high risk of cardiovascular disease. Anrnincrease of 10 mm Hg (more than normal) in diastolic blood pressure leads to relativelyrnincreased risk of stroke and cardiovascular disease up to 37%. Moreover, hypertension mayrnimpair vision. The symptoms...

Background: Cervical cancer remains a major cause of morbidity and mortality among womenrnin the world. It has been estimated that about 500,000 cases of cervical cancer occur worldwidernyearly, with 85% occurrence in resource-poor countries. In Ethiopia, cervical cancer is the 2ndrnmost common...
This project is concerned with the enumeration of a combinatorial object, ordered tree,rnwith respect to different parameters such as, number of edges, vertices, and path lengths.rnA known combinatorial argument is used to prove that among all ordered trees the ratiornof the total number of...
use of regional climate model (RCMs) outputs in hydrological impact assessment has given due attention on the world. Studies that evaluate downscaled simulations of General Circulation Models (GCMs) by Regional Climate Models (RCMs) for African basins are noticeably missing. Recently, the...
Background: - Stunting reflects chronic under nutrition during the most critical periods ofrngrowth and development in early life. Children whose height-for-age Z-score was belowrnminus two standard deviations from the median of the World Health Organization referencernpopulation were considered...
In this project report, explicit ffnite di_erence scheme for the linear heatrnequation in an insulated bar in one space dimension is considered. Thisrnmethod is used to solve the partial derivatives in the partial di_erential equationsrnat each grid point that are derived from neighboring values by...
The distribution of crops with distance from the homestead was studied in 324 peasant faImsrnin Fontanina village (South Welo). Edaphic, climatic and socio-cultural factors playrnimpOliant roles in the distribution of crop species. Farmers categorized their farms into threernmain classes and each...
The objective of this thesis work is to model stream flow at the outlet of the gauged Gumararnwatershed and analyze the associated uncertainty that can affects the accuracy in estimation ofrnthe stream flow. Having good certainty on simulated flow helps planners and policy makers tornimplement...
Using an Amharic version of the CNSIE (Children'srnNowicki-Strickland Internal-External Locus of Control Scale ) ,rn360 4th through 12th graders (186 of which were males and 174rnfemales) were randomly selected and studied . Following thernpilot study, during which the instrument was tested...
A graph is said to be planar if it can be drown in the plane so that no two edges intersect exceptrn(possibly) at their ends vertices.It is of practical interest to able to determine whether a graph isrnplanar or not, our interest is how to check whether the graph is planar or not . In this...
Water distribution systems are designed to fulfill all requirements of potable water needed forrnintended purposes. Initial system designs frequently consider any anticipated changes likely tornhappen. However, as time elapsed they slowly begin to fail to satisfy customers’...
This study was conducted on chickpea growing in farmers’ fields with the help of farmers’rnknowledge. The main focus of the field study was the main production areas of Ethiopia thatrninclude areas in 32 districts distributed in five regions (Amhara, Oromia, Tigray, SouthernrnNations...
This study was conducted to quantify the likely impacts and benefits of current and futurerndevelopment options in the Blue Nile basin using simulation approach.
