Allelopathic effects and bio-insecticidal potential of sphaeranthus suaveolens in common bean farming in Northern Tanzania
(NM-AIST, 2021-07)Weeds and insect pests are amongst the serious constraints in common bean farming in most parts of Tanzania. However, weeds with allelopathic and insecticidal properties if well manipulated can be used to manage insect ... -
Antimicrobial investigation of Tephrosia Vogelii hook.f from Hai District in Tanzania towards development of antifungal agents for topical application
(NM-AIST, 2021-06)Infectious diseases such as fungal diseases are the global health problem. Moreover, antimicrobial resistance to modern fungicides and antibiotics is even perplexing in the health settings. Such situation needs serious ... -
Assessing intensification options of common bean cultivation to improve food security on smallholder farms in the Northern Highlands of Tanzania
(NM-AIST, 2021-07)Complementarities of common bean (Phaseolus vulgaris L.) with non-legume food crops and their significances to the agricultural systems are underexploited. Based on the description of this study, eight options were ... -
Assessing the potentials of agricultural ecosystem pollination services to improve bean yield in smallholder farming systems
(2020-04)Pollination services by insects contribute to production in 75% of food crop species. When promoted through agro-ecological intensification (AEI), pollination can narrow yield gaps in smallholder farming systems. The ... -
Assessment of the status of African Baobab populations and fatty acids composition of its crude oil in semi arid areas of Tanzania
(NM-AIST, 2021-07)Baobab (Adansonia digitata L.) is a deciduous non-timber tree species that is facing severe threats from both anthropogenic and climatic pressures across its range states. Additionally, baobab seed oil has been used ... -
Biomonitoring of pesticides exposure and the fate of pesticides use among smallholder vegetable producers in Tanzania
(NM-AIST, 2020-08)This study assessed drivers of increased and changing patterns of pesticide use, levels of Acetylcholinesterase (AChE) inhibition, associated health effects and co-exposure risks of pesticide residues and bacterial ... -
Characterization of mutations in drug resistant tuberculosis and diagnostic challenges in referral health facilities, Tanzania
(NM-AIST, 2019-03)Tuberculosis remains one of the world’s deadliest infectious diseases in resource-limited settings, including Tanzania. Diagnostic challenges and minimal information on resistant tuberculosis complicate building effective ... -
Colorectal cancer epidemiology in Tanzania: patterns in relation to dietary and lifestyle factors
(NM-AIST, 2019-01)Chronic non-communicable diseases are increasingly captured as contributing to morbidity and mortality in low and middle income countries. This study has designed to investigate the epidemiology of colorectal cancer and ... -
Design of burner and study of combustion characteristics of pyrolysis oil from biomass
(NM-AIST, 2017-12)Conversion of biomass to fuel provides a positive contribution for fossil fuel replacements. In addressing challenges associated with the combustion of pyrolysis oil (bio-oil), this research aimed at developing a burner ... -
The distribution, control techniques and impact of Parthenium hysterophorus on flower visitors and soil chemical properties in Meru district, Tanzania
(2020-08)In Tanzania, the invasive plant Parthenium hysterophorus threatens natural and semi–natural environments. Little is known about how this species affects plant–pollinator interactions and soil–chemical properties. Roadside ... -
Ecological effects of selected invasive plants and their nature based management approaches
(NM-AIST, 2017-12)Biological invasions are one of the major threats to most ecosystems as they often suppress native plant species. This suppressive effect is usually costly and irreversible hence calling for effective management strategies ... -
Epidemiology of intestinal schistosomiasis and efficacy of single versus repeated dose praziquantel treatments among schoolchildren in Rorya district, Northwestern Tanzania
(NM-AIST, 2018-12)In Schistosoma mansoni endemic areas, administering repeated treatments may increase praziquantel cure rate (CR) and egg reduction rate (ERR), thereby improving morbidity reduction and hastening achievement of transmission ... -
Evaluating performance of the improved hybrid passive and active mode solar dryers for processing Mangoes and Pineapples
(NM-AIST, 2021-07)Farmers in East Africa have no access to modern processing technologies because they are costly and high-energy demanding to operate. As a result, they solely rely on the traditional open sun drying (OSD) method, which ... -
Evaluation of maize accessions for diversity, yield and tolerance to maize lethal necrosis disease in Tanzania
(NM-AIST, 2017-12)Maize (Zea mays L.) is among the most important crops in Tanzania with still low average yield of 1.2 metric tonnes per hectare as compared with potential yields of 4 to 5 metric tonnes per hectare. Low yield is due to a ... -
