Abstract: Most rural populations in developing countries use surface water which is turbid in appearance and contaminated with human feces which needs treatment. Even if there are synthetic chemicals that can reduce turbidity and pathogenic organisms from drinking water, they are neither cost effective nor eco-friendly. Instead, natural coagulants are eco-friendly solutions with minimum health risks if properly tested and promoted to be used by community dependent on such unsafe water source...
Abstract: Teaching methodology has a greater impact on the way students learn from teachers and tutors. However traditional class rooms are meant for rote learning, hence, there exists some challenges in promoting “in-depth learning” among the learners when it comes to teaching complex ICT concepts. This paper has been developed based on the experience of introducing an integrated approach towards promoting in-depth learning and understanding by the students. This integrated approach com...
Abstract: Food security issue is one of the critical concern and top priority area for developing countries. Having clear picture on food security status and its determinants helps policy makers to devise appropriate policies that enhance food security. Hence, this study aims to determine the food security status of the households, its determinants, and identify coping strategies used during food shortage in Oda Bultum district of West Hararghe zone, Oromia National Regional State. By using ...
Abstract: This study set out to assess the determinants of milk market supply and channel choices in the study area of Sodo Zuria district of SNNPR, Ethiopia. The study employed two-stage sampling technique to draw 120 sample respondents. Simple descriptive statistical analysis such as mean, standard deviation, percentage, and multiple linear regression and multivariate probit were used to analyze the data. Based on descriptive statics the major channels identified in the study area were sma...
Abstract: The first experimental observation of spin-orbit (SO) coupling in Bose Einstein Con densates (BECs) provided an interesting new platform to explore a fascinating and growing field of research and lead to rich physical e↵ects. In ultracold atomic sys tems,the synthetic SO coupling can be generated using two counter-propagating Ra man lasers that couple two hyperfine ground states. Motivated by these experimental findings, some theoretical activities have been committed to the phys...
Abstract: The main purpose of this study was to propose and analyze a nonlinear mathematical model for the transmission dynamics of cervical cancer due to human papillomavirus with vaccination. The aim of this study is to investigate the dynamics of cervical cancer and analyze a deterministic mathematical model for the spread of cervical cancer due to HPV dynamics with vaccination. To conduct the study, a deterministic mathematical model system of ordinary differential equation and numerical...
Abstract: In Ethiopia microfinance institutions are becoming increasingly essential instruments in reducing poverty. Improving the delivery of financial services to the poor helps the poor to increase their disposable income, asset ownership, and cushion consumption during food deficit periods. Accordingly, Oromia Credit and Saving Share Company has been providing formal financial services for rural households in Oromia region for the last two decades. Large number of studies examined the im...
Abstract: This dissertation was composed of four experiments. In the first experiment, effects of different processing methods(roasting, boiling and germination) on proximate composition, some mineral and antinutrient contents of finger millet was evaluated. In the second and third experiments, the replacement effect of roasted finger millet grain for maize in starter and finisher broiler diets on feed intake, body weight, blood hematology, carcass parameters and meat chemical composition we...
Abstract: Frequent use of antibiotics to stimulate growth and health of animals is becoming a common animal production practice. However, this leads to the development of antibiotic-resistant populations of microorganisms. In this context, alternatives like herbs and spices to antibiotics are of importance, as they are natural products. Therefore, the purpose of this study was to (1) evaluate the effects of Lepidium sativum (Garden cress, GC, Experiment I) and Capsicum frutescens (Hot red pe...
Abstract: A total of 180 Cobb 500 day old broiler chicks were randomly distributed into 15 pens. Five different rations consisting different inclusion levels of Tomato Waste Meal (TWM) were prepared and randomly assigned to treatments to evaluate the growth performances, carcass characteristics and selected hematological and serum biochemical parameters of the chicks. The inclusion levels of TWM were 0% (T1), 3% (T2), 6% (T3), 9% (T4) and 12% (T5). The experiment was conducted for a period o...
Abstract: The experiment was conducted at Haramaya University compound, to evaluate three beneficial local microorganism (BLM) harvesting protocols and the effect of application rate and ensiling period of barley straw (BS) with beneficial local microorganism solution on its silage quality. The three procedures Niva, Rodrigueze and Davenport were used for production of beneficial local microorganism solution with three replication in a completely randomized design for each treatment (procedu...
Abstract: The issue of ensuring food and nutrition security has become a global agenda, particularly for low-income countries with high population growth rate. In Ethiopia, food insecurity and undernutrition are worsening despite numerous policies and programmes geared towards improving household calorie intake and access to nutritious foods. As a tool, understanding the major causes of food and nutrition insecurity is important for interventions. Therefore, this study was initiated to estim...
Abstract: This study was initiated to evaluate the productive and reproductive performances of crossbred dairy cattle at Holetta research center dairy farm. Overall, 19,454 crossbred dairy cattle performance records were used for the study. Non-genetic and genetic analysis on the performance of crossbred dairy cattle were applied for estimation. The GLM and regression analysis procedure of SAS 2004 software was employed to determine the fixed and crossbreeding effects of year, season, parity...
Abstract: Homegarden agroforestry system mostly constitutes complex multi-strata than other agroforestry systems. The aim of this study was to assess the structure, composition and diversity of plant species growing in homegarden agroforestry system and to evaluate the economic contributions of homegardens to households in Bulen district, North-West Ethiopia. The study was conducted in five kebeles of the Woreda, which were randomly selected. Systematic random sampling procedure was employed...
Abstract: Food insecurity is widespread in Menz Gera District. The study was intended to assess the household food insecurity situation in Menz Gera District using 150 randomly selected sample households. The Household Calorie Acquisition (HCA) was used to measure the diet quantity aspect of food insecurity, and 2200Kcal/day/AE was used as a food security line. Based on this measure the incidence, gap and severity of food insecurity were computed using the FGT poverty index and results 84.7,...
