(NM-AIST, 2020-12)
This study aimed at investigating the levels and distribution of progesterone in receiving waters
and wastewaters in Arusha, a fast-growing urban area and third largest city in Tanzania. Also,
intend to assess the ...
Lawsone, lawsone ether and bilawsone for dyesensitized solar cells application
(NM-AIST, 2020-02)
Dye-sensitized solar cells (DSSCs) had turned up as a novel class of low-cost solar cells that
can be fabricated easily compared to silicon solar cells. The DSSCs based on natural sensitizers
are able to generate clean ...
Impact of climate change on groundwater recharge in lake Manyara catchment
(2020-08)
This study aimed to estimate the groundwater recharge of the Lake Manyara catchment (7920 km2) in two different time intervals, historical 1988-2018 and near-future 2021-2050 climatic condition. This study analyzed the ...
Production of biodiesel from neem seed oil using calcinated banana ash/ li-cao/fe2(so4)3 blends as a catalyst
(2020-08)
Biodiesel is a possible remedy to the present toxic, finite sources and ever-diminishing crude
fuels. Non-edible and locally available (Azadirachta indica) Neem Seed Oil (NSO) as a
second-generation feedstock was transformed ...
Geological and hydro-geochemical assessment of fluorine around mount Meru, northern Tanzania
(NM-AIST, 2020-03)
Areas around Mt. Meru are among the areas in Tanzania where climate change, population
growth and high fluoride levels in much of the water sources lower availability of water for
domestic ...

(Authorea, 2020-10)
In this study, land-use/cover pattern of the UNESCO world heritage site, Ngorongoro Conservation Area; is analyzed
using the CA–Markov model with the help of RS and GIS. Hybrid classification techniques ware used to monitor ...
Assessment of fluoride bioaccumulation in catfish grown in fluoride rich waters
(NM-AIST, 2021-08)
Fluoride bioaccumulation in fish poses a significant impact to their growth performance,
survival and consequently to the upper trophic levels. Few studies have reported the impact of
high fluoride concentration and their ...
Assessment of fluoride removal in a batch electro‒coagulation process
(NM-AIST, 2021-06)
A presence of excessive amounts of fluoride than the prescribed standards has been reported
in sources of domestic water supply around mount Meru slopes and other parts in Tanzania
while efforts to remove the excessive ...
Performance of horizontal subsurface flow constructed wetland integrated with floating wetland and anaerobic baffled reactor in treating seed production wastewater
(NM-AIST, 2021-04)
Discharge of untreated or partially treated industrial wastewater is the major contributor to aquatic
environmental pollution. Seed producing industrial wastewater is composed of high organic
matter, nutrient, and suspended ...
