Geochemical Distribution of Trace Elements in Groundwater from the North Mara Large-Scale Gold Mining Area of Tanzania
(Ground Water Monitoring and Remediation, 2016-05)
The infl uence of large-scale mining operations on groundwater quality was investigated in this study. Trace element concentrations in groundwater samples from the North Mara mining area of northern Tanzania were analyzed. ...
Comparative Study of Pb2+ Removals and Isotherms by Physically - and Chemically - Modified Agro - Wastes from Tanzania
(Gwangju Institution of Science and Technology, 2016)
Materials and Methods Raw corn and rice husk were washed several times using DIW to remove extraneous dirt and contaminants. The husks were then dried at 110 ºC overnight to remove moisture. Dried husks were then ground ...
Semi-Transparent Building Integrated Photovoltaic Solar Glazing: Investigations of Electrical and Optical Performances for Window Applications in Tropical Region
(Hindawi, 2019-12-17)
Integrating solar PV technology with semi-transparent windows permits multifunctional operation as electricity generation and allowing natural light to enter the building, hence overall energy efficiency improvement. The ...
Effect of Industrial Dust Deposition on Photovoltaic Module Performance: Experimental Measurements in the Tropical Region
(Hindawi, 2019-12-20)
Dust particle accumulation affects outdoor photovoltaic module transmittance of solar cell glazing and thus leads to significant degradation of conversion efficiency owing to lower irradiance reaching the surface. In this ...
Experimental Investigations of Oxidation Stability of Biodiesel Produced from Manketti Seeds Oil (Schinziophyton rautanenii)
(ACS Publications, 2011-04-12)
In this study, biodiesel from Manketti seeds oil (Schinziophyton rautanenii) was investigated to determine its suitability for use as a petrodiesel substitute. The fuel-related properties of Manketti oil methyl ester (MOME) ...
Characterization of Polycaprolactone and Rice Husk Silica Composite (PCL-SiO2) by E-Spinning to Apply Supporter for Drug Release
(IOP Publishing Ltd, 2017)
Abstract. Polycaprolactone (PCL) is an interesting material to apply biomedical field owing to
its biodegradability and biocompatibility which is suitable for a specific site with longer
healing times. Blending the polymer ...
Qualitative soil moisture assessment in semi-arid Africa – the role of experience and training on inter-rater reliability
(Copernicus Publications, 2015-08-10)
Soil and water management is particularly relevant in semi-arid regions to enhance agricultural productivity. During periods of water scarcity, soil moisture differences are important indicators of the soil water deficit ...
Seasonal and spatial variation of surface current in the Pemba Channel, Tanzania
(PLOS ONE, 2019-01-07)
The surface current speeds within the Pemba channel were examined using 24 years of drifter data received from the Global Drifter Program. This study aimed to uncover varying surface current in the Pemba Channel in different ...
Status of Biomass Derived Carbon Materials for Supercapacitor Application
(Hindawi, 2017-01-31)
Environmental concerns and energy security uncertainties associated with fossil fuels have driven the world to shift to renewable energy sources. However, most renewable energy sources with exception of hydropower are ...
Extracts from field margin weeds provide economically viable and environmentally benign pest control compared to synthetic pesticides
(Public Library of Science, 2015-11-23)
Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but most progress has been shown in the laboratory. Consequently, research on pesticidal plants is failing to address gaps ...
