Managing non-revenue water in Mwanza, Tanzania: A fast-growing sub-Saharan African city
(Elsevier Ltd., 2021-07)High non-revenue water (NRW) and unreliable water supply services are major challenges in operations of the water infrastructure of most fast-growing cities in developing coun- tries. In this study, an analysis of the ... -
Short-term forecast techniques for energy management systems in microgrid applications
(NM-AIST, 2023-07)In the 2015 Paris Agreement, 195 countries adopted a global climate agreement to limit the global average temperature rise to less than 2°C. Achieving the set targets involves increasing energy efficiency and embracing ... -
Remediation of soils contaminated with fluoride using seaweed-derived materials: case of slopes of mount Meru
(NM-AIST, 2023-08)While exposure to low fluoride is essential for stronger bones and teeth, exposure to high concentration (> 3 mg/L/day) leads to hyperostosis and osteoporosis. This research evaluated the role of fertilizer application ... -
Combination of natural betanidin dye with synthetic organic sensitiser towards dye-sensitised solar cell application
(NM-AIST, 2023-05)Betanidins belong to natural red-purple pigments betacyanins, which experimentally demonstrated good light adsorption in a visible range and might be suitable for the dye sensitised solar cell (DSSCs). Instability is a ... -
Hydrologic responses to climate and land use/cover changes in world heritage site of Ngorongoro conservation area and surrounding catchments, northern Tanzania
(NM-AIST, 2023-01)In Tanzania, various studies have analyzed the impact of climate and land use/cover changes on water resources. However, information on the interactions between climate and land use/cover change, temporal and spatial ... -
Investigating the potential of producing eco-friendly liquid biofertilizer from domestic wastewater
(NM-AIST, 2023-08)Water bodies experience environmental challenges such as eutrophication due to poor management of domestic wastewater in developing countries. Meanwhile, the explosion in population of the world has resulted in a 1.8 ... -
Rheological and physicochemical analysis of non- edible oils used for biodiesel production
(NM-AIST, 2023-07)The knowledge of the physicochemical and rheological flow characteristics of biodiesel feedstock is used for quality control in production, storage and transportation processes. Moreover, the knowledge is applied in ... -
Removal of arsenic in a sand filter coupled with zero valent iron
(Elsevier, 2023-06-22)Arsenic (As) in wastewater has negative effects on the environment and human health, hence As containing wastes must be handled properly. Given the accessibility of metallic iron, studies investigating into the potential ... -
Removal of fluoride and pathogens from water using the combined electrocoagulation-inline-electrolytic disinfection process
(IWA Publishing, 2023-07-01)The consecutive removal of fluoride (defluoridation) and pathogens (disinfection) in drinking water through combined electrocoagulation-inline-electrolytic disinfection (EC–ECl2) process with aluminum and dimension-stable ... -
Striding towards self-sustainability using aluminium from Tanzanian Kaolin for combination tanning system
(Dresden-Germany, 2019)Sustainability is a key factor which controls future leather manufacture. Developing several new technologies is one of the primary agendas for sustainability. However, developing countries are facing several challenges ... -
Influence of duct configurations on the performance of solar-assisted heat pump dryer for drying tobacco leaves
(NM-AIST, 2023-08)nadequate storage facilities and preservation techniques lead to a decrease in the quality of agricultural products. Application of modern processing techniques has reduced post-harvest losses of agricultural crops. ... -
A quantity-quality tradeoff: Water quality and poverty assessment of drinking water sources in Southern Tanzania
(NM-AIST, 2023-06)Regardless of being essential for human survival, access to potable water is still a problem in many rural African communities with increasing exposure to waterborne illnesses. This study aimed at establishing accessible ... -
Experimental investigation of the variation in the potential of selected natural rocks as thermal energy storage materials
(NM-AIST, 2023-08)Fossil fuels cause greenhouse gas emissions and are perceived to deplete, hence the use of renewable energy is considered crucial. These renewables include the use of solar thermal energy in concentrated solar power (CSP) ... -
