International Journal of Animal and Veterinary Advances , 2012,
Abstract: A cross sectional study was conducted on equine from November 2010 to February 2011 to determine the seroprevalence of African Horse Sickness Virus (AHSV) antibodies and identification of potential risk factors in equine population in selected areas of Arsi and Bale zones. A total of 480 serum samples were collected. Competitive ELISA test was employed to determine the presence of African Horse Sickness (AHS) antibodies. The seroprevalence of 28.63 and 14.23% were found in the Arsi and Bale zones, respectively. The apparent seroprevalence was found to be 24.60% in donkey, 20.34% in horses and 20% in mules. The overall seroprevalence of AHS virus was found to be 21.45%. There was no significant variation between the horse, donkey and mules in the seropositivity (p>0.05). Statistically significant difference (p<0.05) in the seroprevalence was observed in the different study area, confirming the existence of agro-ecology variation in the occurrence of AHS, thus higher seroprevalence of AHS was documented in midland (31.38%) followed by highland (15.06%). Significant variation was not observed in seroprevalence among age groups and sex of equine. All age groups as well as male and female of equine population were equally affected. Knowledge base of equine owner about AHS, Clucoides vector and mode of transmission of the disease in the study areas were assessed through structured questionnaire. The survey result indicated that almost all equine owners did not know about Clucoides vector and mode of transmission. Therefore, there should be awareness reaction about AHS and Clucoides vector among the people through an organized extension package to the present study areas.

Evaluating the outcomes of DOTS program is essential for recognizing and amending system failures before the incidence and proportion of resistant isolates rise. In this study, we seek to evaluate the impact of DOTS strategy on tuberculosis treatment success rate in Dabat, northwest Ethiopia. Medical records of 1305 pulmonary and extrapulmonary tuberculosis patients registered from 2007 to 2012 at two health centers in Dabat district, northwest Ethiopia, were reviewed. Treatment outcomes and forms of tuberculosis were assessed according to WHO guidelines. Descriptive analyses were performed using frequencies and percentages. Treatment success rate was observed in 1146 (87.8%) patients. Out of these, 534 (89.1%) of the males and 612 (86.7%) of the females were successfully treated. It was also true in 338 (87.8%) of the smear-positive pulmonary tuberculosis patients, 473 (85.7%) of the smear-negative pulmonary tuberculosis patients, and 335 (91.0%) of the extrapulmonary tuberculosis patients. In conclusion, treatment success rate in the current study was slightly higher than the WHO international updated target for the period 2011 to 2015. However, this doesn’t mean that there will be no need for further enhancement of supervision and monitoring techniques, strengthening counseling and health education programs, and improving the quality of laboratory diagnostic services.

Abstract: The study was undertaken in the northern periphery of the country, Tigray region, north-west Tigray zone, Tahitay Adiyabo district from February to March, 2017. For this study, four Kebeles were selected purposively based on the presence of two major community groups (Tigrayans and Kunama) and presence of camel species and other livestock species. Seventy-two (72) households per district, of which 38 households from two kebeles for Kunama community and 34 households from two kebeles for Tigrayan community groups were selected randomly. A software package of SAS (2008) was employed to generate descriptive statistics for qualitative and quantitative data. As the study revealed, three-fifth and two-fifth of the respondents in the study area were illiterate and attended primary education respectively. The two community groups were significantly (P < 0.05) different on educational status and Tigriyans respondents were more educated than the other counterpart. More than 2/3 children (7 - 17 years of age) of the respondents in the study area were attended school. Exceptionally, more than 75% of the children for Tigriyan community group in the district were attended school whereas 3/5th of Kunama community children were attended school education. Average family size per household in the study area was 6.22 ±

Soil degradation in the form of soil erosion is a serious and continuous environmental problem in Jabi Tehinan Woreda. Uncontrolled land use, deforestation, over cultivation, overgrazing and exploitation of biomass for firewood, construction and other household uses due to increasing population ultimately lead to severe soil erosion. The impact of natural hazards like erosion can be minimized and ultimately controlled by disaster preparedness maps. Therefore, the overall objective of this paper is to quantify and map an estimated soil loss by examining different topographic and anthropogenic factors for the planning and implementations of sustainable soil conservation and management system in the study area. This study had integrated Geographic Information System (GIS), Remote Sensing (RS) and Multi-Criteria Evaluation (MCE) techniques to quantify and map erosion vulnerable areas using RUSLE model. Slope gradient, slope length, soil type, soil conservations techniques, cover management and rainfall variables were used as input model parameters/variables. The data had been collected and analyzed from different land sat imageries, SRTM data, topomaps and point interpolations of primary data. Finally, the aggregated effects of all parameters had been analyzed and soil loss from the area was calculated using RUSEL models. After analyzing all model parameters, areas in steeper slope with Lithosols, Eutric Nitosols, Orthic Luvisols, croplands, bare lands and river banks have been identified as the most erosion vulnerable areas. Quantitatively, an estimated annual soil loss in Jabi Tehinan Woreda ranges from nearly 0 in south and central parts of the area to 504.6 t/ha/yr in steeply sloping mountainous areas of the north and north-eastern parts of the catchments.

Abstract: This work focuses on the theoretical investigation of the coexistence of superconductivity and ferromagnetism in the superconducting HoMo6S8. By developing a model Hamiltonian for the system and using the Green’s function formalism and equation of motion method, we have obtained expressions for superconducting transition temperature (Tc), magnetic order temperature (Tm), superconductivity order parameter (D) and magnetic order parameter (η). By employing the experimental and theoretical values of the parameters in the obtained expressions, phase diagrams of energy gap parameter versus transition temperature, superconducting transition temperature versus magnetic order parameter and magnetic order temperature versus magnetic order parameter are plotted separately. By combining the phase diagrams of superconducting transition temperature versus magnetic order parameter and magnetic order temperature versus magnetic order parameter, we have demonstrated the possible coexistence of superconductivity and ferromagnetism in superconducting HoMo6S8.<

Abstract: The need to create and maintain industrial peace, in one hand, protect the fragile interest of workers on the other side to boost economic development have been critical issues which have attained significant consideration from states. To that end, they introduced at international and national levels different set of legislations regulating employment relations. Among other things, working time limit has meticulously been introduced to safeguard the rights of workers, who are generally with the lesser bargaining power, and make the labor more productive. Ethiopia has accepted this notion of delimitating working hours, and adopted legislations. However, it has become a public secret that such rules have not been maintained in practice and that the enforcement mechanism appeared meager. Though researches have been made in different part of the world; in Ethiopia, particularly in Dire Dawa, the factors contributing for long working hours have not been addressed. There are, however, indicators that particularly waiters are working for longer hours than what the law stipulates. In a town dubbed as industrial corner, this factor should not be left unconsidered if the aspired objective of the labour regulation is really to be met. This research, hence, took the first step in studying the existence of this violation, and investigating the contributing factors. The data were collected through structured questionnaires and interviews, and samples were taken using stratified systematic sampling method. Data were analyzed through quantitative (descriptive analysis and logistic regression model) and qualitative techniques. Then, job insecurity, lack of legal awareness, culture of the work, salary, tips, dependents, and level of education have been found out to be contributing factors, and their level of significance has also been established. It has also revealed that the absence of strong enforcement mechanisms contributed for the apparent non-adherence to the rules so delimiting working hours.

Abstract: Freight transport system that minimizes costs, increase conveniences, and environmentally safe has become the agenda worldwide since long before. This study was made with the main objective of assessing intermodal termed as “multimodal” freight transport service in Ethiopia. Data was collected by using structured questionnaire from randomly selected customers and multimodal freight transport section employees of Ethiopian Shipping and Logistics Service Enterprise. The study was made in two stages using customers: first, they were asked to evaluate their satisfaction with the multimodal freight transport system; second, to evaluate their comparative satisfaction with the segmented/“uni-modal” freight transport system against five major freight transport performance indicators. Customers were also asked to identify and rank top ten problems of freight transport logistics in Ethiopia. Data were analyzed using SPSS and excel sheets with descriptive statistics and the results were depicted using charts and tables. The study indicated that majority of customers were either dissatisfied or very dissatisfied with many of the performance indicators. The employees evaluated their organization as well performing relatively on more performance indicators. Both customers and employees evaluated the documentation performances as satisfying but cost and convenience as dissatisfying performances. Customers identified repetitive custom checking and waste of time in custom inspections process as the most severe problem in freight transport logistics in Ethiopia. The implementation of intermodal freight transport system to bring better change in import-export freight transport logistics of Ethiopia was in bitter challenge for customers due to a number of problems, except documentation performance that showed betterment.

Abstract: In order to determine the proportion of primary and secondary infertility, the 1991 - 1995 medical records of clients were revised and analyzed. Three thousand three hundred and eighty women indicated their desire to undergo infertility investigations and then counselled for (Visit I), but only 2570(76%) registered for investigation. Ninety six percent of the attendants of the infertility clinic were females, and 58.1% of the registered females were less than 30 years of age and 18% above 35 years. Twenty-two (21.6%) had no formal education and 40.2% had primary education. About 38 (38.3%) had secondary school education and above. The majority of the clients were married (95.0%), housewives (70.4%), and reside in Addis Ababa (87.5%). The cumulative dropout rate was 91.9% of which 86.1% were those who were lost to follow-up. Of the physically examined (2475), 195 (7.9%) were actively censored. The largest number of the dropouts was immediately after visit three followed by visit one. This review shows that only 7% of the counselled and 9.3% of the booked completed the preliminary infertility investigation schedule. Forty-two women reported pregnancy during the process and were excluded from the dropout list. The follow-up discontinuation in respect to all selected socio-demographic variables was again indicated to be highest immediately after visit three. The investigation completion rate is shown to increase with the level of education, and among merchants and office workers. About 50% of the clients sought medical assistance after five to 10-years of infertility. Irrespective of the type, the shorter the duration of infertility, the better was the investigation completion rate. The proportion of primary to secondary infertility was about 2:3. Many infertile women who sought medical assistance failed to complete the essential preliminary investigations and were lost to follow-up. Although further study is necessary to answer why they discontinued, the socio-demographic characteristics indicate that those who are likely to be better economically are better completers of the investigations. The fact that neither the institution nor other centers can make all the essential investigations like seminal fluid analysis, HSG, diagnostic endometrial sampling, etc. in one setting with affordable fee charge may have contributed significantly to this high dropout rate.
