Abstract: The objective of the paper is to model forest cover change (FCC) from perceived land use and land cover changes in the Bosomtwe district of the Ashanti region, Ghana. Questionnaire and interviews were administered and conducted among 270 proportionately sampled respondents respectively, from 14 communities, on the basis of their respective populations. The quantitative data was analyzed using inferential and descriptive statistical tools in SPSS v.16.

Abstract: Within the UK there are several areas, including sizeable parts of north-west, central and eastern England, smaller parts of south and north east England, central Scotland and Northern Ireland, which have the potential to produce shale gas. Shale gas is produced by hydraulically fracturing shales, a process popularly known as fracking, which releases the gas and allows it to flow. This process typically involves drilling a borehole down into the earth and then using a mixture of water and chemicals, pumped at high pressure into the shale, to open up narrow fractures, which in turn creates paths for the gas to flow into the borehole and hence back to the surface.

Abstract: Women in urban India have low levels of physical activity, and the lack of safe spaces to be physically active is likely an important factor. The objectives were to develop a spatial database of areas and facilities in order to assess conduciveness to physical activity in Greater Noida, to assess the safety and usability of roadways and community parks in this area.

Abstract: New biocomposite films from Polyvinyl alcohol (PVA)/Palm kernel shell powder (PKSP) were prepared by solution casting method. The effect of PKSP addition on the film was studied based on the tensile properties, physical properties and biodegradability. From tensile test, it was found that the tensile properties decreased with the increasing PKSP loading in the composition.

Abstract: Bioleaching methods are environmentally benign and economical options for extraction of rare earth elements (REEs) from low grade REE ores. We conducted shake-flask and column bio-leaching (Acidithiobacillus ferrooxidans) studies with a low grade phosphate ore constituting REEs, fluorapatite, and silicates.

Abstract: To understand and assess the effects of nanoparticles (NPs) on the environment, should be well established quantitatively the concentration-response relationships. Also relate the potential effects on selected variables of response with the exposure to sub-lethal levels of NPs. In this work, we describe the ecotoxicological evaluation of negative and positive coated silica NPs (Si-Nps) on coelomic cells from Eisenia fetida.
