Enjera baking is the most energy intensive activity in Ethiopia; and preparation of enjera is rather a long process relative to other Ethiopian food. The aim of this thesis work is to investigate the performance characteristics and efficiency of the electric baking pan („mitad‟)...
20829. Fringe Spacing And Strain Analysis Using Laser Moire Fringe Projection Technique
The spacing between fringes is crucial for testing materials based on Moir´e technique.rnIn this work, the spacing between two consecutive bright (or dark) fringes, C , isrndetermined, for different grating separation , . The behavior shows that as the anglernbetween the gratings increases, the...
20830. An Inversion Model Of Receiver Function For Moho Depth Determination Beneath Locations Of The Ethiopian Seismic Network Stations And Their Surroundings
Moho depths or crustal thicknesses at four stations of the Ethiopian Seismic StationrnNetwork (ESSN) are estimated from Receiver Functions studies. We usedrnhigh quality seismic data recorded at ANKE (Ankober), DILA (Dila), HARE (Harar)rnand SEME (Semera) stations for earthquakes located at...
20831. Bacterial Uropathogens And Their Drug Resistance Pattern In Diabetic Patients Attending Yekatit 12 Hospital Medical College Addis Ababa Ethiopia
Background: Urinary tract infection (UTI) is one of the most common infections encounteredrnand treated worldwide. UTI has been reported to be around four times higher in diabetics compared tornnon-diabetic patients. Since diabetic patients are at a high risk of development of UTIs, it...
20832. Mass Concentrations And Metals Speciation Of Urban Atmospheric Aerosols In Addis Ababa Ethiopia
Air aerosol samples for TSP (total suspended particulate) and coarse particulatern(particle matter with aerodynamic diameter 2.5–10 μm, PM2.5–10) and metallicrnelements were collected during February 2008 to July 2008 in urban and peri-urbanrnareas of Addis Ababa, Ethiopia. The...
20833. Practice Of Commercial Banks In Ethiopia Assessment Of Liquidity Risk Management
The main purpose of the study was to assess the liquidity risk management practice ofrncommercial banks in Ethiopia. To deal with the problem, three fundamental researchrnquestions were formulated that stress on the impact of liquidity on performance of banks,rnthe existence of standardized...
20834. Identification Of The Major Causes To The Delay In The Construction Of 4060 Saving Houses Project In Addis Ababa
Delay is the most frequent problem in the construction industry particularly in developing countries like Ethiopia. However, it can be better managed when the causes are identified and action is taken by the concerned bodies. The main objective of this research is to identify the major causes to...
20835. Geoelectrical Investigation For The Assessment Of Ground Water Distributions In Becho Plain South West Showa
This thesis work deals with the regional interpretation of electrical resistivity sounding, survey,rncarried out in the Becho plain, Southwest Showa. The principal objective is to study the groundrnwater conditions such as depth to the water table, thickness and lateral boundaries of aquiferrnand...
20836. Performance Of Ethanol Water Mixture As Fuel For Household Stove
Ethiopia is one of the world’s least developed countries where population pressures and anrnover reliance on traditional biomass fuels have led to deforestation. The combustion ofrnunsustainably harvested biomass releases large quantities of greenhouse gases into thernatmosphere and when...
