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 ...
Physicochemical and Microbiological Variations in Rivers on the Foothills of Mount Meru, Tanzania.
(International Journal of Scientific & Engineering Research, 2017-09-09)
Little is known on the physicochemical and microbiological changes in Nduruma, Tengeru and Maji ya Chai Rivers. Such important
variations were studied during wet and dry seasons in 2015. Water samples from various ...
Hydrogen sulfide and ammonia removal from biogas using water hyacinth-derived carbon nanomaterials
(Academic Journals, 2017-07-31)
The presence of hydrogen sulfide (H2S) and ammonia (NH3) in biogas pose serious human health and
environmental challenges. In this study, H2S and NH3 were successfully removed from biogas using
water hyacinth-derived ...
Seasonal water chemistry variability in the Pangani River basin, Tanzania
(Springer, 2017-09-17)
The stable isotopes of δ18O, δ2H, and 87Sr/86Sr and
dissolved major ions were used to assess spatial and seasonal
water chemistry variability, chemical weathering, and hydrological
cycle in the Pangani River Basin (PRB), ...
Invasive weeds with pesticidal properties as potential new crops
(Elsevier, 2017-12-30)
Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but only a handful have been commercialised and developed as non-food cash crops. One of the reasons why pesticidal plants ...
Spatial Distribution of Soil Hydrological Properties in the Kilombero Floodplain, Tanzania
(MDPI, 2017-11-30)
Analysis and interpretation of soil properties dynamics is a keystone in understanding the hydrologic responses and yield potential of floodplain wetlands. This study characterizes the distribution and spatial trends of ...
Invasive weeds with pesticidal properties as potential new crops
(Elsevier, 2017)
Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but only a handful have been commercialised and developed as non-food cash crops. One of the reasons why pesticidal plants ...
Nutrients’ distribution and their impact on Pangani River Basin’s ecosystem – Tanzania
(Taylor & Francis Group, 2017-05-05)
Surface and groundwater from Pangani River Basin (PRB) were sampled in dry and wet seasons,
analysed for dissolved organic and inorganic nutrients (N, P, Si and Urea). There was spatial and
seasonal nutrients’ variability, ...
Performance of constructed wetland integrated with sand filters for treating high turbid water for drinking
(IWA Publishing, 2017-03)
The feasibility of constructed wetland integrated with sand filters (CW-SFs) for treating high turbid water for drinking
was investigated. Turbid water of .1,000 NTU from Nadosaito dam in Monduli District, Tanzania was ...
Measurement of Pozzolanic Activity Index of Scoria, Pumice, and Rice Husk Ash as Potential Supplementary Cementitious Materials for Portland Cement
(Hindawi, 2017-08-06)
This work investigated the properties of scoria and pumice as supplementary cementitious materials (SCMs) for Portland cement
and compared to those of rice husk ash (RHA). X-ray fluorescence, X-ray diffraction, and ...
