The importance of agriculture in mitigating the effects of overdependence on crude oil export to boost Nigeria economy cannot be overemphasized. Coffee is an important foreign exchange earner and Nigeria has vast potential to resuscitate production, proce... see more

The problem of planning spacecraft minimum time reorientation maneuvers under boundaries and path constraints is addressed. Keep-out constraints for an optical sensor are considered and end-point constraints are imposed to obtain a rest-to-rest maneuver. ... see more

Erosion of sand particles is one of the serious problems in the oil and gas production industry. There is strong evidence that most wells now produce increased sand as the major oil and gas production declines. This is a widespread problem as it can affec... see more

The complex processes in edge tokamak plasma are affected (among others) both by resonant magnetic perturbation (RMP) and by plasma turbulence. RMP is nowadays considered to be a candidate for the mitigation of the edge-localized modes (ELMs). The effect ... see more

In this paper, numerical simulations of particle migration in lubricating grease flow are presented. The rheology of three lithium greases with NLGI (National Lubricating Grease Institute) grades 00, 1 and 2 respectively are considered. The grease is mode... see more

Shear induced diffusion (SID) based flow segregation is a technique that can be used for concentration and fractionation purposes, and it has the potential to become an economical and sustainable alternative for e.g., membrane separation. When compared to... see more

This study assesses seasonal particle size distribution (PSD) dynamics inside a waste stabilization ponds (WSP) (Buguruni, Tanzania) to understand settling dynamics of wastewater particles with an interest in helminth eggs. Results indicate that particles... see more

Alumina nanoparticle is one of the attractive nanoparticles synthesized by the plasma method. The oxidation step in this method is challenging to explain experimentally. This work was to perform a molecular dynamics simulation to determine the oxidation m... see more
