Evaluation of selected botanicals as insecticides against cabbage insect pests in Tanzania
(NM-AIST, 2022-06)Synthetic pesticides are frequently and unwisely used to control cabbage insect pests by smallholder farmers despite the environmental pollution and insect pests’ resistance development. This work assessed the insecticidal ... -
Experimental investigation of the variation in the potential of selected natural rocks as thermal energy storage materials
(NM-AIST, 2023-08)Fossil fuels cause greenhouse gas emissions and are perceived to deplete, hence the use of renewable energy is considered crucial. These renewables include the use of solar thermal energy in concentrated solar power (CSP) ... -
Experimental Investigations of Oxidation Stability of Biodiesel Produced from Manketti Seeds Oil (Schinziophyton rautanenii)
(ACS Publications, 2011-04-12)In this study, biodiesel from Manketti seeds oil (Schinziophyton rautanenii) was investigated to determine its suitability for use as a petrodiesel substitute. The fuel-related properties of Manketti oil methyl ester (MOME) ... -
Extracts from field margin weeds provide economically viable and environmentally benign pest control compared to synthetic pesticides
(Public Library of Science, 2015-11-23)Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but most progress has been shown in the laboratory. Consequently, research on pesticidal plants is failing to address gaps ... -
Fast Rate Production of Biodiesel from Neem Seed Oil Using a Catalyst Made from Banana Peel Ash Loaded with Metal Oxide (Li-CaO/Fe2 (SO4)3)
(Hindawi, 2020-08-27)Biodiesel is a possible remedy to the present toxic, finite sources and ever-diminishing crude fuels. Nonedible and locally available (Azadirachta indica) neem seed oil (NSO) as a second-generation feedstock was transformed ... -
Fertility management for maize cultivation in some soils of Western Kenya
(Elsevier, 2011-12-01)Soil fertility loss in Western Kenya is exacerbated by inadequate nutrient management and causes reduced maize yields. Given the diversity of soil types, cropping seasons, and the resource endowment of farmers, the magnitude ... -
Fish bladder-based activated porous carbon/co3o4/tio2 composite electrodes for supercapacitors
(NM-AIST, 2020-02)Supercapacitors as energy storage devices depend on electrode materials, electrolyte and conductive additives. In relation to the above, this master’s dissertation specifically provides a scientific understanding and ... -
Functional impacts of polyaniline in composite matrix of photocatalysts: an instrumental overview
(Royal Society of Chemistry, 2023-05-22)The challenges associated with photocatalysts including their agglomeration, electron–hole recombination and limited optoelectronic reactivity to visible light during the photocatalysis of dye-laden effluent make it necessary ... -
Geochemical Distribution of Trace Elements in Groundwater from the North Mara Large-Scale Gold Mining Area of Tanzania
(Ground Water Monitoring and Remediation, 2016-05)The infl uence of large-scale mining operations on groundwater quality was investigated in this study. Trace element concentrations in groundwater samples from the North Mara mining area of northern Tanzania were analyzed. ... -
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 ... -
Groundwater recharge estimation and quality on the southern slopes of mount Kilimanjaro, Tanzania
(NM-AIST, 2021-07)This study was undertaken to estimate groundwater recharge rates using three methods (water table fluctuation (WTF), chloride mass balance (CMB) and soil moisture balance (SMB), as well as assessing the impact use of the ... -
Health Risk Assessment of Trace Elements in Soil for People Living and Working in a Mining Area
(Hindawi, 2021-07-02)The present study used soils collected from a small-scale gold mine area to determine the health risks due to trace elements to the at-risk population in the study area. The work involved 74 soil samples from four sampling ... -
Household food insecurity and gender inequity is associated with high prevalence of maternal depression amongst female farmers with young children in rural Tanzania
(The Federation of American Societies for Experimental Biology, 2018-10-03)There is growing recognition of the importance of maternal mental health for the well-being of both mothers and children. In addition to being of importance to public health concern on its own right, maternal depression ... -
