The impact of electronic-electrical waste on human health and environment: A systematic literature review
Sub-Saharan Africa has become one of the leading destinations for used equipment or Electronic-Electrical waste (e-waste-or-EEW) from developed economies, making its management more urgent than ever. Most studies have articulated the serious impact of e-waste disposal to the environment and public human health. Little attention or consideration has been devoted to the management of e-waste in Uganda despite the...

Economic impacts of optimizing energy recovery in clinker cooler using clinker cooler bed as a case study
This paper tends to analyze one critical area “pyro system” in cement production process where energy is been lose and ways on how some of these energies can be recovered back into the system and also analyzing the cost benefits. This led to the modeling of a clinker cooler known as “test rig”. This model was used to study the operating system of the existing running plant. The test rig was...

Effect of speed, feed rate and tray angle on the dehulling, cleaning and grain loss from an acha (Digitaria exilis) dehulling machine
This study determined the effect of cylinder speed, feed rate and tray angle on the dehulling efficiency and the effect of fan speed, feed rate and tray angle on the cleaning efficiency and grain loss from an acha (Digitaria exilis) dehulling machine in a 3 × 3 factorial experimental design in three replicates. The cylinder speeds were 1500, 2000 and 2500 rpm and the fan speeds were 160, 185 and 213 rpm. The feed...
