Determinants of manual control of water hyacinth expansion over the Lake Tana, Ethiopia

Water hyacinth is an exotic freshwater weed damaging wetland resources over the Lake Tana basin, Ethiopia. Different measures, including manual labour and harvesting machinery are in use to reduce its damage and expansion. Yet, the invasion of the weed appears expanding its scope across the wetlands of the Lake. This paper presented the study made to identify determinant factors affecting manual control of water hyacinth expansion over the Lake wetlands. It tried to analyse the expansion trend of the water hyacinth and community efforts to control its extension. Data were gathered from questionnaire surveys, group discussions, interviews and field observations. Descriptive statistics and binary logistic regression were used for data analysis. The study revealed that the water hyacinth cover in the Lake’s wetland increased from ≤10, 000 ha in 2011 to over 50, 000 ha in 2017. Wetland terrain, water depth, food availability, farming time, employment and government support were found significantly influencing the manual control practices of households. Hence, government support must increase to motivate people involvement in manual weed removal campaigns. Micro-relief maps and floating boats need be readily available to help participants easily identify risky terrains and expand the physical weed removal into the deeper waters.Key Words: Water hyacinth, Invasive weeds, Manual control, Wetlands, Lake Tana, Ethiopi

Analysis of Grain Traders’ Performance in Ethiopia: The Case of Contribution of Social Capital

This article examines the performance of 206 grain traders in 20 markets found in Amhara, Tigray, Oromiya and SNNPR of Ethiopia. The study adopts Fafchamps and Minten (1999) approach and used multiple regression model. The study identified that financial capital (working capital), social capital (using intermediary at the time of sale and customer relationship), human capital (farming experience) and transaction cost (having mobile, Oromiya and SNNPR) affected traders’ performance. The findings suggested adding working capital through different means (like access to credit through micro finance institutes, banks, etc.) with planned and market assessment, establishing licensed and well organized brokerage strengthen traders business relationship with regular customers in a formal or informal way, farmer-trader linkages are recommended through the dissemination of information (e.g. workshops) and training on quality and production management, establish and strengthen, a reliable, permanent,  public domain market information and other infrastructure are important to enhance traders performance, in turn encourage farmers to produce more and maximize benefit from grain market.

Assessment of laboratory logistics management information system practice for HIV/AIDS and tuberculosis laboratory commodities in selected public health facilities in Addis Ababa, Ethiopia

Introduction: Logistics management information system for health commodities remained poorly implemented in most of developing countries. To assess the status of laboratory logistics management information system for HIV/AIDS and tuberculosis laboratory commodities in public health facilities in Addis Ababa. Methods: A cross-sectional descriptive study was conducted from September 2010-January 2011 at selected public health facilities. A stratified random sampling method was used to include a total of 43 facilities which, were investigated through quantitative methods using structured questionnaires interviews. Focus group discussion with the designated supply chain managers and key informant interviews were conducted for the qualitative method. Results: There exists a well-designed logistics system for laboratory commodities with trained pharmacy personnel, distributed standard LMIS formats and established inventory control procedures. However, majority of laboratory professionals were not trained in LMIS. Majority of the facilities (60.5%) were stocked out for at least one ART monitoring and TB laboratory reagents and the highest stock out rate was for chemistry reagents. Expired ART monitoring laboratory commodities were found in 25 (73.5%) of facilities. Fifty percent (50%) of the assessed hospitals and 54% of health centers were currently using stock/bin cards for all HIV/AIDS and TB laboratory commodities in main pharmacy store, among these only 25% and 20.8% of them were updated with accurate information matching with the physical count done at the time of visit for hospitals and health centers respectively. Conclusion: Even though there exists a well designed laboratory LMIS, keeping quality stock/bin cards and LMIS reports were very low. Key ART monitoring laboratory commodities were stock out at many facilities at the day of visit and during the past six months. Based on findings, training of laboratory personnel's managing laboratory commodities and keeping accurate inventory control procedures were recommended.Key words: Logistics management information system, stock outs, laboratory commoditie

Design of Passive down Draft Cool Tower for 100 m2 Auditorium

A passive down draft evaporative cooling (PDEC) tower is design to capture the wind at high temperature typically at 40ο C and above the top of tower and cool the outdoor air using water which is allowed to flow through shower and due to evaporation of water out door air gets cooled. Many different types of PDEC exist. This paper explains design of PDEC tower. It is a parallel flow heat exchanger with hot and cold fluid are in direct contact with each other. The wet bulb temperature of air is the lowest possible temperature of the air leaving the tower and entering in air conditioned space. It is suitable in hot dry climate due to large difference between dry and wet bulb temperatures. The mathematical model predicted with the variation of wind speed from 1 m/s to 6 m/s with outside air temperature 35 ο C and relative humidity 20 %, a tower height of 6 m is required

Epidemiology of low back pain among nurses working in public hospitals of Addis Ababa, Ethiopia

Background: Low back pain (LBP) related to Nursing Profession, is a very common public health problem throughout the world. Various risk factors have been implicated in the etiology and LBP is assumed to be of multi-factorial origin as individual, work-related and psychosocial factors can contribute to its development. The aim of this study was to determine the prevalence and to identify the risk factors of LBP among Nurses working in Addis Ababa City Public Hospitals, Ethiopia, in the year 2015. Addis Ababa University, Black-Lion (‘Tikur Anbessa’) Hospital-BLH, is the country’s highest tertiary level referral and teaching Hospital. The three departments in connection with this study: Radiology, Pathology and Orthopedics, run undergraduate and residency programs and receive referred patients from all over the country.Methods: A cross-sectional study with internal comparison was conducted throughout the period October-December, 2015. Sample was chosen by simple random sampling technique by taken the lists of Nurses from human resource departments as a sampling frame. A well-structured, pre-tested and selfadministered questionnaire was used to collect quantifiable information. The questionnaire included socio-demographic, back pain features, consequences of back pain, work-related and psychosocial factors. The collected data was entered in to epiinfo version 3.5.4 and was analyzed by SPSS. A probability level of 0.05 or less and 95% confidence level was used to indicate statistical significance. Ethical clearance was obtained from all respected administrative bodies, Hospitals and study participants.Results: The study included 395 Nurses and gave a response rate of 91.9%. The mean age was 30.6 (±8.4) years. Majority of the respondents were female (285, 72.2%). Nearly half of the participants (n=181, 45.8% (95% CI (40.8%- 50.6%))) were complained Low Back Pain. There were statistical significant association between Low Back Pain and working shift, physical activities at work; sleep disturbance and felt little pleasure by doing things.Conclusion: A high prevalence of Low Back Pain was found among Nurses working in Addis Ababa Public Hospitals.
