. Influence of selected tillage operations on draft power and penetration resistance of a crusting soil.
(2000)
Depending on the top and subsoil textures, semi-arid soils exhibit cohesive and frictional properties that are associated with the relatively high soil strength, bulk density and penetration resistance. The objective of ...
Effect of air maldistribution on performance of an evaporator
(2000)
An experimental facility has been constructed to enable the effects of air flow non-uniformity on the transfer performance of refrigerant evaporators to be investigated. This is based on an open-circuit wind tunnel, which ...
Conservation tillage implements and operations for soil and water management
(2000)
We investigated whether resistant pollen genotypes can be selected for when the maternal plants are infected and whether infection can result to changes in the pistil nutrient level influencing reproductive outcome. Both ...
Monitoring of suspended particulate matter (SPM), heavy metals and other parameters in some workplaces
(2000)
This report presents results of measurements of sound levels, chemical analysis of air particulate matter and soil samples from two factories in Nairobi. A preliminary assessment of suspended particulate matter (SPM) in a ...
