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 ...
Synthesis of mesoporous carbon from non-biodegradable plastic bags for water purification: methylene blue removal
(NM-AIST, 2017-12)
In the present work, the mesoporous carbon materials with pore diameter of 14.2 nm and
specific surface areas of 15.18 (m2g-1) identified by Brunauer, Emmett, and Teller (BET)
were synthesized from non-biodegradable ...
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, ...
Simulation, performance analysis and improvements of solar farm installation in Tanzania
(NM-AIST, 2019-04)
With the environmental advantages of solar energy, the use of solar photovoltaic (PV) in electricity generation is encouraged by Tanzanian governments, however, the number of institutions that are benefiting from installing ...
Biodiesel production from parinari curatellifolia seeds oil using basic heterogeneous catalyst derived from tamarindus indica fruit shells
(NM-AIST, 2019-03)
Biodiesel is an alternative fuel to mineral diesel. It is produced from abundant and easily available renewable resources of animal fats and vegetable oil. However, the cost of oil feedstock is the major obstacle towards ...
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 rice husk ash and vermiculite materials in the production of ceramic tiles
(NM-AIST, 2019-03)
The challenging issues in ceramic tiles are low mechanical strength, thermal discomfort and
high production costs. Apart from strength the technical functions of floor tiles based on
thermal insulation is very important ...
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 ...
Study of crustacean biomass wastes for water defluoridation
(NM-AIST, 2018-09)
High levels of fluoride (F-) in community drinking water supply is recognized as one of the major public health problems. Until now no efficient and affordable F- removal technology exists in many regions. This research ...
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 ...
