Turbulent Natural Convection in an Enclosure with Colliding Boundary Layers
(2018)When a heated plate is exposed to ambient room air without an external source of motion, a movement of air is experienced as a result of density gradients near the plate. This process is known as natural convection. The ... -
Effect of growth temperature on the structural, optical and luminescence properties of cadmium telluride nanoparticles
(2018-01)Cadmium telluride (CdTe) has been successfully prepared by a simple wet chemical process at different reaction temperatures. Temperature is one parameter that thermodynamically plays an important role in controlling the ... -
EAFRINET and the Taxonomic Impediment: perspectives from the developing world
(2018-01)Taxonomic capacity in the developing world is seriously lacking, and as such species identification for both pests and useful species is seriously hampered. Some of these species are key indicators of environmental health ... -
