Theoretical study of structural and thermodynamic properties of gaseous metal hydrides m2xh4 (m = li, na; x = be, mg)
(2016-04)
This study aimed to explore the properties of the complex hydrides which seem to be the promising candidates for hydrogen storage materials. The geometrical structure, vibrational spectra and thermodynamic characteristics ...
Risk of heavy metals exposure through consumption of rice from Kahama and Geita districts
(2016-04)
Heavy metals exposure is associated with various human health problems. This research aimed at determining the levels of heavy metals in paddy soils and in polished rice from villages around the artisanal gold mining areas ...
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 ...
Ecosystem services for crop protection in bean fields in Moshi rural, along the slopes of Mt. Kilimanjaro Northern Tanzania
(2016-02)
The natural ecosystem, in and around bean fields potentially offer beneficial services that assist
bean productivity. This study was conducted to investigate the distribution of beneficial
invertebrates and plants and ...
Constraints and opportunities for coffee productivity on the slopes of mt. Kilimanjaro in the face of climate change
(2016-04)
Limited scientific information on decreasing productivity of Arabica coffee (Coffea arabica L.) in Tanzania has been observed. Poor agricultural practices, pests, diseases and climate change are among important factors ...
Water quality variation and pollutants transformation in the Nadosoito dam of Arkatani village, Monduli district
(NM-AIST, 2019-02)
The study aimed at assessing seasonal dynamics of water quality parameters, transformation of selected pollutants and seasonal diversity of selected microorganisms (Cyanobacteria) in Nadosoito dam of Arkatani Village, ...
Theoretical and experimental studies of combination of synthetic dye (indoline d131) and natural dye (lawsone) for dye sensitized solar cells applications
(NM-AIST, 2019-02)
Dye sensitized solar cells (DSSCs) convert visible sunlight to electricity using a wide band semiconductor. The DSSCs have attracted many researchers due to their environmental friendliness, low manufacturing cost and ...
Risks of sanitation facilities to groundwater pollution in Babati town, Tanzania
(NM-AIST, 2019-03)
Despite of its importance for human consumption groundwater resource is under threat of
overexploitation and pollutions. The study to assess the risks of sanitation facilities to
groundwater pollution was carried out in ...
Investigation of combination effect of natural dye (crocetin) and synthetic dye (indoline d205) for dye sensitized solar cells application
(NM-AIST, 2019-02)
Dye-sensitized solar cells (DSSCs) are reckoned as emerging next-generation solar cells of a high potency. Co-sensitization of dyes facilitates widening of the light absorption range of a sensitizer and is one of possible ...
Removal of hydrogen sulfide and ammonia from biogas using Oldoinyo Lengai Volcanic ash
(NM-AIST, 2019-02)
Oldoinyo Lengai mountain located in Northern Tanzania is the only active natrocarbonatite volcano with unusually alkali-rich natrocarbonatites which are not found elsewhere in the world. Volcanic ash formed earlier during ...
