Assessing Land Use/Cover dynamics of the Ngorongoro world heritage site in Tanzania using a hybrid CA–Markov model
(Authorea, 2020-10)In this study, land-use/cover pattern of the UNESCO world heritage site, Ngorongoro Conservation Area; is analyzed using the CA–Markov model with the help of RS and GIS. Hybrid classification techniques ware used to monitor ... -
Life cycle analysis of potential municipal solid wastes management scenarios in Tanzania: the case of Arusha City
(Springer Nature, 2021-01-07)The municipal solid wastes (MSW) management technologies in most cities of developing countries pose a continuous risk of contaminating the environment and affecting human health adversely; often because MSW technologies ... -
Predicting land use/cover changes and its association to agricultural production on the slopes of Mount Kilimanjaro, Tanzania
(Taylor & Francis Online, 2021-01-11)Increasing demand for food production results in Land use and land cover (LULC) changes, which afflicts the provision of ecosystem services in high mountain areas. This work used time-series LULC and selected spatial metrics ... -
Betanidin isomerisation and decarboxylation, thermodynamic and charge transfer dye properties towards dye sensitised solar cells application
(John Wiley & Sons, Inc., 2021-01-25)Along with attractiveness of natural dyes for solar technologies, the instability is a well‐known drawback of the dyes, which impedes their usage for dye sensitised solar cells (DSSCs) application. The planar isomer appeared ... -
Effects of Climate Smart Agricultural practices and Planting Dates on Maize Growth and Nutrient Uptake in Semi-Arid Tanzania
(International Journal of Biosciences, 2020-05-15)The shift of growing season’s onset due to rainfall and seasonal variability are among the climate change impacts affecting agricultural productivity in semi-arid. Previous studies have also noted the seasonal variations ... -
High energy density materials based on fluorinated bridged trinitromethyl azo triazole derivatives: a quantum chemical study of thermodynamic and energetic properties
(Springer Nature Switzerland AG., 2020-10-19)High energy density materials (HEDM) have gained extensive attention due to their energetic properties and safety issues. Nitro and fluoro groups, among others, have become viable substituents on the triazole framework ... -
Two-stage banana leaves wastes utilization towards mushroom growth and biogas production
(Springer Nature Switzerland AG., 2020-11-20)Banana leaves wastes (BL) were subjected to fungal treatment using Pleurotus ostreatus to produce edible mushrooms and biogas in the anaerobic digestion process. Effects of fungal treatment on mushrooms production, lignin ... -
Theoretical and Experimental Performance Analysis of a Novel Domestic Biogas Burner
(Hindawi, 2020-09-16)The inefficient indoor burning of fuelwood on traditional cookstoves generates pollutants, primarily carbon monoxide and many other human health-damaging emissions. It is from this risk that it is necessary to have an ... -
