Environmental effect of mineral exploitation in Nigeria

The three stages of mineral development, viz exploration, mining and processing, have caused different types of environmental damages, which include ecological disturbance, destruction of natural flora and fauna, pollution of air, land and water, instability of soil and rock masses, landscape degradation and radiation hazards. The environmental damage has in turn resulted in waste of arable land, as well as economic...

Effect of coconut fibre filler on the cure characteristics physico–mechanical and swelling properties of natural rubber vulcanisates

Investigation into the effect on the rheological, physico – mechanical and swelling properties of natural rubber vulcanizates using coconut fibre as fillers were carried out. The coconut fibre was characterized in terms of pH, moisture content, ash content, loss on ignition, conductivity, particle size and surface area. The physico – mechanical properties as well as the equilibrium swelling characteristics...

Utilization of coconut fibre carbon in the removal of soluble petroleum fraction polluted water

Activated carbon powder was obtained by treating coconut fibre with ammonium chloride and carbonized at 400oC. The powdered activated carbon was sieved. The portion that passed through a 212 um and retained on a 90 um mesh size was used for this study. The treatment was done to increase the surface area and the adsorption site of the carbon. The activated carbon was characterized in terms of pH, surface area, loss on...

Some electromagnetic transition properties and mixing ratios of tellurium isotopes

IBM-2 calculation is presented for the low-lying states in the even-even 122-128Te core nucleus. We developed the projection by using the F-spin formalism from the operator of IBA-2 model over the operator of IBA-1 model space. With the help of this projection IBA-2 Hamitonian parameters are obtained and we explore the energy levels and the electric quadrupole transition probabilities B...
