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 ... -
Farmer-led feeding and breeding approaches for overcoming seasonality-driven milk fluctuations in smallholder dairy farms in Kenya and Tanzania
(NM-AIST, 2021-07)Seasonality-driven changes in farmer-led feeding and breeding approaches are increasingly captured as contributing to fluctuations in milk yield and reproductive performance of dairy cows in smallholder dairy farms in ... -
