A large proportion of world energy sources is renewable energy. Improved biomass cookstoves are recently developed devices for domestic cooking utilizing biomass as fuel through gasification. In Ethiopia, biomass is the most widely used source of energy for cooking and heating applications. This study attempted to enhance the thermal efficiency of domestic cookstoves used in Ethiopia. The developed model was tested experimentally using the water boiling testing protocol (WBT). Results showed that the stove had a thermal efficiency of 45.17%, with specific fuel consumption of 11.53 g/L and 43-48 minutes of cooking time. The mathematical model was implemented and validated, and the experimental results showed that there was an improvement of the stove, as well as reduced fuel consumption and cooking time.

Hepatitis B virus infection is one of the commonest occupational risks in healthcare workers. However; there is limited evidence regarding the prevalence of hepatitis in health professionals in Ethiopia. Objective. This study was aimed at assessing the prevalence of hepatitis B and associated factors in health professionals. Methods. Institution based cross-sectional study was conducted among health professionals at University of Gondar Hospital from January to February, 2015. Self-administered questionnaire was used to collect sociodemographic variables and blood sample was also taken to determine hepatitis B virus sero-status. Chi square test with 95% confidence interval (CI) was computed to assess the associations of different factors with hepatitis B infection. Result. A total of 332 health professionals (with a response rate of 92.2%) participated in the study. Most (98.5%) of health professionals were not vaccinated for hepatitis B. The prevalence of hepatitis B ...
