Impacts of future climate and landuse changes on surface-groundwater balance in Usangu catchment
(NM-AIST, 2019-02)
This study was undertaken to assess the impacts of future climate and land use/cover changes on surface-subsurface water balance in Usangu catchment, located in the Southern highlands of Tanzania. The objectives of the ...
Optimization of incineration process
(NM-AIST, 2019-02)
Municipal solid waste management has become a challenge in many cities in the developing countries due to the poor methods of waste disposal, which increase the risk of the spread of diseases, leach and increase the demand ...
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 ...
Optimization of biogas production process in solid state digesters: option for minimizing deforestation in dry areas
(NM-AIST, 2019-03)
Questionnaire survey, satellite images of 1987, 1997, 2002 and 2017 were used to assess energy sources, demand and the impact of fuel wood use to forest cover changes in Meru and Mwanga districts. The major energy sources ...
Removal of heavy metals from water by capacitive deionization electrode materials derived from chicken feathers
(NM-AIST, 2019-03)
Capacitive deionization (CDI) is an emerging desalination technology based on the principle of electrical double layer capacitors. When the voltage is applied to the surface of the electrodes, electrodes become oppositely ...
Evaluation of dielectric and mechanical strength of high voltage porcelain insulators made from Tanzania ceramic materials
(NM-AIST, 2019-03)
The study has evaluated the dielectric and mechanical strength of high voltage porcelain insulators made from Tanzania local ceramic raw materials. The ceramic raw materials involved were; Pugu Kaolin Same clay, vermiculite, ...
