Propane (HC – 290) as an Alternative Refrigerant in the Food Transport Refrigeration Sector in Southern Africa – a Review
(Universitas Muhammadiyah, 2022)Most of the food transport trucks in Sothern Africa are equipped with refrigeration and air conditioning systems filled with fluorocarbon refrigerants such as R404A to facilitate the heat transfer process. These refrigerants ... -
Correction to: Arduino-based low-cost electrical load tracking system with a long-range mesh network
(Springer, 2020)A system that combines the advantage of the long-range (LoRa) communication method and the structural characteristics of a mesh network for an LoRa mesh network-based wireless electrical load tracking system is proposed. ... -
Tin molybdenum mixed metal oxides catalyst for oxidative desulfurization of model diesel
(NM-AIST, 2023-08)This study reports on synthesis, characterization, and catalytic activity of mesoporous mixed metal oxides of tin (Sn) and molybdenum (Mo) for sulfur removal from model diesel. Variable synthesis conditions, namely ... -
Surface water – groundwater interactions: A case of a shallow semi-closed lake catchment in northern Tanzania
(NM-AIST, 2023-06)Conjunctive use of surface water and groundwater is rapidly growing in many developing countries as an adaptation strategy to climate variability and change. However, the interactions between the groundwater and the ... -
What influences individuals to invest in improved sanitation services and hygiene behaviours in a small town? A formative research study in Babati, Tanzania
(Public Library of Science, 2022-07-21)Sub-Sahara African countries face immense challenges in ensuring adequate sanitation and hygiene behaviours to the rapidly growing populations. Attempts to address these chal lenges require empirical evidence to inform ... -
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 ... -
