Abstract: The importance of the classical limit of the maximum rotational energy transfer, (ΔE)max, has been reviewed for a two dimensional hard ellipsoid potential model over a wide range of energies, reduced mass of the system, potential functions and potential parameters for the F2-He system. It has been found that (ΔE)max, predicted by the hard ellipsoid potential is comparable to a well-known parameter lΔEl* given by the two parameter Power- gap law. The numerical equivalence of (ΔE)max and lΔEl* has been verified for various types of potential surfaces, collision energy and the mass of the system. Such equivalence suggests that the value of (ΔE)max can be used as one parameter lΔEl* of the power -gap law. ,

Title	:	Investigation of the Effects of Using Gas Flare to Dry Tapioca (Kpokpo-Garri) at Gana Flow-Station in Agbarha,Delta State, Nigeria
Country	:	Nigeria

Abstract: Local women in the Niger Delta use oil companies' gas flare sites to dry a popular cassava base food, kpokpo-garri (tapioca).This work is on the investigation of the effects of using gas flare to dry tapioca in the Niger Delta region of Nigeria. Two samples of tapioca dried with gas flare at Gana flow station, Agbarha were analyzed using a Unican 929 atomic absorption spectrophotometer for the presence of hazardous heavy metals. Fe, Mn, Pb, Cd, Ni and Zn were found in the dried tapioca in quantities above WHO safe limits. These make the dried tapioca unsafe for consumption. There is therefore the need for alternative means such as sun or oven to dry tapioca.

Title	:	Integrated Geophysical Survey In A Refuse Dumpsite Of Aarada, Ogbomoso, Southwestern Nigeria

Abstract: Surface geophysical survey was conducted around Aarada refuse dumpsite, Ogbomosho, Oyo State, Nigeria to locate leachate plumes migration pathways using the very low frequency electromagnetic and vertical electrical sounding techniques. Eight VLF-EM profiles of length 70 to 150m with 10m interstation spacing and seven Vertical Electrical Soundings with current electrode separation varying from 150 to 200m were established. The analyzed VLF-EM data revealed the presence of conductive pollutants (leachate plumes) at the subsurface while the geoeletric sections generated from the processed VES data showed that the leachate plumes have actually migrated to a depth of 5.4m in the area which confirmed the VLF-EM results.
Keywords: Groundwater, Health Hazard, Leachate Plume, Vertical Electrical Sounding, Very Low Frequency Electromagnetic.
