    Advanced Education and Training Programs to Support Renewable Energy Investment in Africa
    (International Journal of Education and Practice, 2017) Kimuli, Daniel; Nabaterega, Resty; Banadda, Noble; Kabenge, Isa; Ekwamu, Adipala; Nampala, Paul
    African countries have initiated programs to generate electricity from renewable sources such as; wind, solar, biomass and hydropower. These initiatives are intended to reduce the carbon footprint of these countries in the wake of heavy dependency on fossil fuels and also provide cheap and accessible electricity to rural areas. These renewable energy programs are expected to deliver regional development and economic empowerment. However, the lack of trained manpower for repair and maintenance of renewable energy technologies devices is likely to result in failure of these technologies, cause losses in revenue and reduction in consumer faith in renewable energy technologies. African universities must be at the core of solving these challenges by training specialized professionals in renewable energy at graduate level and through short courses to meet the increasing demands for qualified human resource to support the sector. Thus to establish the “readiness” of Universities in Africa to offer advanced education and training in renewable energy, a review of all Masters Courses, Ph.D. programs and short courses was carried out. The results identified 21 English-language Masters courses, 3 providers of Ph.D. studies and 9 short courses in or with significant renewable energy content. Generally, there is inadequate advanced training in renewable energy especially at Ph.D. level in Africa thus the need to attract more African Universities to offer such programs at both masters and Ph.D. levels.

    Quantification Of Physico-Chemical Characteristics And Modeling Faecal Sludge Nutrients From Kampala City Slum Pit Latrines
    (Int. J. Res. Eng. Adv. Technol, 2016) Kimuli, Daniel; Zziwa, Ahamada; Banadda, Noble; Kabenge, Isa; Kiggundu, Nicholas; Kambugu, Robert; Wanyama, Joshua; Tumutegyereize, Peter; Kigozi, Julia
    Failure to quantify nutrients in feacal sludge usually leads to its poor disposal resulting into surface water and groundwater pollution. Therefore, this study was conducted to determine and model the distribution of nutrients in pit latrine sludge as a step towards reuse of available nutrients. Sampling was done at 0.0, 0.5, 1.0 and 1.5 m depths from 31 lined and 31 unlined latrines during rainy and dry season. Physico-chemical characteristics such as chemical oxygen demand (COD), dissolved oxygen (DO), moisture content, temperature and nutrients including ammonia,nitrate, total nitrogen, phosphorus and potassium were determined. Results indicated that COD, temperature and DO decreased and moisture content increased with sludge depth. There was no significant variation (P˃0.05) in nutrients and physico-chemical properties except COD. Strong correlations of R2 Adj ˃ 0.85 were obtained between modeled and measured values. The relative root mean square error of the predicted nutrients was less than 10%. Results revealed that the model is good estimator phosphorus concentrations in lined pits followed by total nitrogen in unlined pits and nitrates in lined pits.
