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 ...
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 ...
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. ...
The use of pesticidal plants as environmental friendly Practice for field and storage pests’ management in Common beans and cowpeas
(2016-04)
Infestation caused by insect pests on legumes has been witnessed to cause losses in the fields during cultivation as well as during storage. Use of pesticidal plants is seen as an alternative option although it is not used ...
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 ...
Performance analysis of standalone solar PV panel: case study of Arusha, Tanzania
(NM-AIST, 2019-03)
The purpose of this study was to carry out experimental and theoretical performance analysis of standalone solar Photovoltaic (PV) panel in tropical region. The study concentrated on the influence of poor PV panel positioning ...
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 ...
Inhibition of aluminium corrosion using carica papaya extracts in acidic media (sulphuric acid and phosphoric acid)
(NM-AIST, 2017-12)
Corrosion inhibition of aluminium using Carica papaya leaves extracts in 1M H2SO4 and IM H3PO4 was investigated under different temperatures (30, 40 and 500C) and concentrations (from 20-100 v/v %). The inhibitor was found ...
Theoretical study of structure, vibrational spectra and thermodynamic properties of cluster ions existing in vapours over barium dihalides
(NM-AIST, 2017-12)
Computational and theoretical methods were employed to study the structure, vibrational spectra and thermodynamic properties of cluster ions that were detected earlier in saturated vapour over barium dihalides. The equilibrium ...
Biogas slurry derived mesoporous carbon/metal oxides composites for supercapacitors application
(NM-AIST, 2017-12)
With the increasing utilities of intermittent renewable energies, hybrid electric vehicles and portable
electronic devices, supercapacitors have been identified as one of the solution for energy storage
since they can ...
