An Analysis of Fuel Properties of Fatty Acid Methyl Ester from Manketti Seeds Oil
(Taylor & Francis Online, 2014-11-20)The fatty acid methyl esters (FAME)produced from vegetable oils, animal fats, or waste oils known as biodiesel has attracted attention as possible replacement of fossil fuels. The fuel properties of biodiesel are similar ... -
Analysis of Macro- and Microplastics in Riverine, Riverbanks, and Irrigated Farms in Arusha, Tanzania
(Springer Nature Switzerland AG., 2021-11-16)Microplastics and macroplastics have been reported in different urban rivers and agricultural soil across the globe. However, the interlink between them has not been previously assessed. The present study evaluated the ... -
Analysis of spatio-temporal climate variability of a shallow lake catchment in Tanzania
(IWA Publishing, 2020-04-06)This study analyzed the trends and spatio-temporal variability in rainfall and temperature, and the length of the rainy season (LRS) in the Lake Manyara catchment, Tanzania, covering a period between 1988 and 2018 using ... -
The application of nutrient budget models to determine the ecosystem health of the Wami Estuary, Tanzania
(Elsevier, 2018-04)Using the LOICZ and the UEE models we estimated the nutrient budget in the Wami River estuary, Tanzania, to better understand the functioning of the ecosystem and assess its health. We found that during the wet season, ... -
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 ... -
