(Hindawi, 2020-07-30)
Estimating the conveyance efficiency of traditional irrigation schemes systems is very important. It is because of understanding the
volume of water lost along with the transportation facility, enhancing water usage and ...
The use of pesticidal plants as environmental friendly Practice for field and storage pests’ management in Common beans and cowpeas
(2016-04)
Infestation caused by insect pests on legumes has been witnessed to cause losses in the fields during cultivation as well as during storage. Use of pesticidal plants is seen as an alternative option although it is not used ...
Status of Biomass Derived Carbon Materials for Supercapacitor Application
(Hindawi, 2017-01-31)
Environmental concerns and energy security uncertainties associated with fossil fuels have driven the world to shift to renewable energy sources. However, most renewable energy sources with exception of hydropower are ...
Analysis of spatial and temporal trend of hydro‑climatic parameters in the Kilombero River Catchment, Tanzania
(Springer Nature Limited, 2023-05-15)
Inadequate knowledge on actual water availability, have raised social-economic conficts that
necessitate proper water management. This requires a better understanding of spatial–temporal
trends of hydro-climatic variables ...
