How Can We Represent Seasonal Land Use Dynamics in SWAT and SWAT+ Models for African Cultivated Catchments?
(MDPI, 2020-05-28)In SWAT and SWAT+ models, the variations in hydrological processes are represented by Hydrological Response Units (HRUs). In the default models, agricultural land cover is represented by a single growing cycle. However, ... -
Exploring the future impacts of urbanization and climate change on groundwater in Arusha, Tanzania
(Taylor & Francis Online, 2020-06-22)We combine satellite imagery, urban growth modelling, groundwater modelling and hydrogeological field expeditions to estimate the potential impacts in 2050 of rapid urbanization and climate change on groundwater in Arusha, ... -
Demand-SideManagement of Solar Microgrid Operation: Effect of Time-of-Use Pricing and Incentives
(Hindawi, 2020-06-05)Over 17% of the world’s population lack access to electricity, the majority being in rural areas of sub-Saharan Africa and South Asia. Microgrid technologies are a promising solution towards rural and remote area ... -
Approaches to the mitigation of ammonia inhibition during anaerobic digestion – a review
(IWA Publishing, 2020-06-03)The digestion process of organic waste rich in high ammonia content has always been a gridlock during methanogenesis process. The free ammonia may increase inhibition/toxicity, which in turn affects the microbial community ... -
A computer-based approach for developing linamarase inhibitory agents
(Walter de Gruyter GmbH, 2020-04-18)Cassava is a strategic crop, especially for developing countries. However, the presence of cyanogenic compounds in cassava products limits the proper nutrients utilization. Due to the poor availability of structure discovery ... -
Short-term load forecasting in a hybrid microgrid: a case study in Tanzania
(Journal of Electrical Systems, 2019)Most emerging countries such as Tanzania are promoting rural electrification through installation of microgrids. This paper proposes an approach for short-term day-ahead load forecast in rural hybrid microgrids in emerging ... -
LPG-Fueled Vehicles: An Overview of Technology and Market Trend
(Automotive Experiences, 2020)This article presents an overview of the technology status and market trends of LPG-fueled vehicles through the literature approach to re-evaluate their future. In the review, it is discovered that LPG vehicles are ... -
Optimization of microwave-assisted alkali pretreatment followed by acid hydrolysis of sugarcane straw for production of acetone-butanol-ethanol
(Taylor & Francis Online, 2020-05-07)The production of acetone-butanol-ethanol (ABE) calls for effective pretreatment and hydrolysis techniques to maximize reducing sugar yields. In this study, optimized microwave-assisted alkali (MAA) pretreatment followed ... -
Storage and thermal stability of biodiesel produced from manketti nut oil of Southern Africa origin with the infuence of metal contaminants and antioxidants
(Springer Nature Switzerland AG., 2020-04-20)Biodiesel has widely been produced from common edible oils; however, food versus fuel conficts has motivated researchers to search for other less common feedstock for production of biodiesel. Thus, this study investigates ... -
Removal of fluoride from water using activated carbon fibres modified with zirconium by a drop-coating method.
(Elsevier Ltd, 2020-09-01)Metal-modified carbon materials have been widely used for fluoride removal, but the traditional impregnation by soaking method suffers from low loading of metals and substantial use of chemicals. This study proposed a new ... -
