Estimating Conveyance Efficiency and Maize Productivity of Traditional Irrigation Systems in Usa River Catchment, Tanzania
(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 ...
Thermal Performance Analysis of Solar Dryer Integrated with Heat Energy Storage System and a Low-Cost Parabolic Solar Dish Concentrator for Food Preservation
(Hindawi, 2020-07-30)
Solar energy has become a viable alternative energy because it is a clean type of energy that converts solar radiation into heat energy for various applications such as heating water, power generation, cooking, and food ...
Strength and Durability Properties of Concrete Containing Pumice and Scoria as Supplementary Cementitious Material
(Hindawi, 2021-05-24)
Concrete structures suffer serious deterioration under a corrosive environment. Consequently, the service life of these concrete
structures is decreased and deteriorates under combined attack of sulphate and chlorides. ...
Theoretical and Experimental Performance Analysis of a Novel Domestic Biogas Burner
(Hindawi, 2020-09-16)
The inefficient indoor burning of fuelwood on traditional cookstoves generates pollutants, primarily carbon monoxide and many other human health-damaging emissions. It is from this risk that it is necessary to have an ...
Transformations to groundwater sustainability: from individuals and pumps to communities and aquifers
(Elsevier Ltd., 2021-05-11)
If the success of agricultural intensification continues to rely on the depletion of aquifers and exploitation of (female) labour, transformations to groundwater sustainability will be impossible to achieve. Hence, the ...

(IOP Publishing Ltd, 2017)
Abstract. Polycaprolactone (PCL) is an interesting material to apply biomedical field owing to
its biodegradability and biocompatibility which is suitable for a specific site with longer
healing times. Blending the polymer ...
Qualitative soil moisture assessment in semi-arid Africa – the role of experience and training on inter-rater reliability
(Copernicus Publications, 2015-08-10)
Soil and water management is particularly relevant in semi-arid regions to enhance agricultural productivity. During periods of water scarcity, soil moisture differences are important indicators of the soil water deficit ...
Performance of Sweet Potato’s Leaf-Derived Activated Carbon for Hydrogen Sulphide Removal from Biogas
(Hindawi, 2020-03-01)
In this study, sweet potato leaf activated carbon (SpLAC) was prepared by the chemical activation method using KOH and applied as an adsorbent for H2S removal from biogas. The study focused on the understanding of the ...
Clay-based ceramic materials for water de-fluoridation
(NM-AIST, 2021-08)
Long-term consumption of water with fluoride concentration above the WHO recommended
limit of 1.5 mg/g may cause fluorosis. Low-income communities living in fluoride endemic
regions are more affected as they cannot afford ...
