Characterization of Clays from selected sites for Refractory Application
(2019-11)Clay is a stony or earthy mineral aggregate composed of fine-grained minerals, which are plastic at appropriate water content and hardens up when fired. Clay soils have various mineral groups such as kaolinite, smectites, ... -
Antimicrobial Activity of Root Bark Extracts of Rhus natalensisa and Rhus ruspolii
(Scientific & Academic Publishing, 2019-08)Bacteria and fungi are frequent causes of serious opportunistic infections worldwide. Several effective antibiotic drugs are in the market. However, drug-resistance, side effects and cost of such antibiotics limits their ... -
Mathematical Modeling of Infectious Disease Transmission Dynamics in a Metapopulation
(iosr journals, 2019-11)Epidemic modeling is an important theoretical approach for investigating the transmission dynamics of infectious diseases. It formulates mathematical models to describe the mechanisms of disease transmissions and dynamics ... -
Mathematical Modeling of the Transmission Dynamics of Measles under the Effect of Vaccination.
(iosr journals, 2019-08)Measles virus is a member paramyxoviridae within the genus of morbillivirus. Its genome consist of approximately 16,000 bases of non-segmented single stranded negative sense RNA. This means that the virus is transcribed ... -
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 ... -
