Dam breach analysis is essential for investigating future effects posed to human life andrnproperty by a sudden release of water to the inundation area downstream of a dam. Everyrnconstructed as well as proposed dams need to be analyzed for the possibility of dam breach tornclearly identify the...
A cross sectional study was conducted in eight towns in Oromia regional state, Ethiopia, from December 2019 to May 2020. The Histoplasma capsulatum var farciminosum and other co-infecting bacteria from characteristic lesions of Epizootic Lymphangitis were iaolated and an effect of Dovyalis...
Syphilis is a chronic sexually transmitted disease caused by Treponema pallidum. It is transmissible by sexual contact with infectious lesions, from mother to fetus in utero, via blood transfusion and occasionally through breaks in the skin that come into contact with infectious lesions. If it is...
Anemia is regarded as a major risk factor during pregnancy both for the mother and the fetus. Its severity depends upon the status of the mother in the society. A health center based cross-sectional study was conducted in East Gojjam Basoliben woreda at five health centers from February 4/2018 to...
Urbanization in Ethiopia has increased population densification along with urban infrastructurerndevelopment. Urban growth is linked with the land use change of the city and plays a major role inrnchanging the Drainage condition. The city is exposed to flash floods. Moreover, extensive land...
This study was carried out in Bilate River sub-basin to assess the surface water potential andrndemands. A DEM, LULC and soil data, slope, and climatic data were used to describe thernhydrology of study area. The annual activity level, annual water use rate and the supply data usedrnto estimate the...
Ethiopia is one of the countries harboring many industrial and agricultural institutes like floriculture industry that work on production of flower in high level. Flower farms used to spray Neonicotinoids pesticide chemical to protect insect pests. Honey bees are highly sensitive to neonicotinomide...
California Bearing Ratio (CBR) is a commonly used indirect method to assess the sub gradernsoil strength in pavement design works. However, since CBR cannot be easily determined inrnthe field, civil engineers always encounter difficulties in obtaining representative CBRrnvalues for design of...
Stability and safety are very important issues for embankment dams built in seismicrnregions. Earthquakes impose additional loads on to embankment dams over thosernexperienced under static conditions that could cause settlement and longitudinal andrntransverse cracking of the embankment,...
Batter piles are used when the foundation structure is exposed to a considerable amount ofrnlateral loads to support super structure safely. The behavior of batter piles had for many yearsrnbeen studied by performing laboratory tests. The difficulty of modeling the pile soilinteractionrnrnin the...
In this thesis, the behavior of a single passive pile subjected to uniform and/ orrntriangular lateral soil movement has been carried out by means of a three-dimensionalrnfinite element numerical model using PLAXIS 3D software. The Mohr-Coulombrnconstitutive material law, and linear elastic -...
Currently the issues of sustainable energy demands become critical due to the rapid growth ofrnpopulation and economy. The construction boom in the country has caused the rising of tallrnbuildings for luxury hotels, shopping malls, apartment blocks, etc., particularly in AddisrnAbaba. The...
Among the major root and tuber crops, anchote (Coccinia abyssinica (Lam.) Cogn) is a potencial tuber crop mostly cultivated in western and southern parts of Ethiopia. It serves as a food, social-cultural, medicin and economic plant for the farming communities. The plant is commonly propagated by...
In the present study, the engineering properties of the Jimma volcanic and Makkonnen basalticrnrock formations located in the south-western part of Ethiopia in Wolkite Town are assessed. It isrnaimed to propose a guideline useful in the early stages of site investigation. A systematicrnmethodology...
It is becoming abundant in Addis Ababa, to conservatively place high-rise buildings onrndeeper hard stratum through very long piles. However, the use of piled raft foundationrnseems to be more advantageous than the conventional pile foundation since both the raftrnand piles contribute to the...
Collapsible soils present significant geotechnical and structural engineering challenges forrndifferent types of constructions. These soils suffer volume changes and collapse deformationrnupon wetting. Situations in arid and semi-arid climates favor the formation of the mostrnproblematic...
Soil stabilization is the physical and chemical alteration of soils to enhance their physicalrnproperties. Stabilization can increase the shear strength of a soil and control the shrink-swellrnproperties of a soil, thus improving the load-bearing capacity of a sub-grade to supportrnpavements and...
The subgrade provides the foundation for the pavement material and should be well compacted tornutilize its full strength. The subgrade strength is related to the CBR value of soil. The CBR test isrnlaborious and time consuming and must always be performed on remolded soil samples. The CBRrnvalues...
Hawassa, a lakeside city in southern Ethiopia found at the heart of the East African Rift system,rnhas been frequented with a series of minor to strong earthquakes reaching up to a magnitude of 7.rnA recent minor earthquake caused structural distresses in the city that tempts one to...
