Abstract: A research on the impact of waste disposal site on groundwater resources was conducted around Aarada area, Ogbomosho, Oyo State, Nigeria using electrical resistivity (vertical electrical sounding) and hydro-physicochemical methods. This study was carried out to map the contamination patches at the subsurface and investigate the contamination level of the various hand dug wells situated in the area. A total of seven VES were carried out with length ranging between 80 to 130m. The hydro-physicochemical analysis was conducted at the peak of the wet season on nine water samples taken from nine different hand-dug wells in the research area. The result obtained from the interpreted VES data revealed leachate plumes at the subsurface in the study area. The outcome of the hydro-physicochemical method revealed hazardously high values of Fe2+, Pb2+, Zn2+, Cu2+ and NO3 - to further support the findings from the VES survey..
Keywords: Contaminants, Groundwater, Health Hazard, Hydro-Physicochemical Analysis, Leachate Plume, Vertical Electrical Sounding.

Abstract: Wind is one of the renewable resources in Zeway which is unexploited. This paper presents a number of issues related to the Assessment of wind energy resource based on 16 years long- term measured data of daily wind speed and direction, 3-hourly measured wind data at 10 m height, which are obtained from meteorological station and Analysis carried out By using Rayleigh stastical Analysis for wind data analysis and Matlab software used for data acquisition. This study indicates that Zeway, has energy potential available with the maximum and minimum average wind speed respectively, 4.9 m/s and 1.5 m/s and average wind power density also varies with maximum and minimum values respectively, 68.6 w/m2 and 0.0 w/m2 and the Results suggested that wind energy must be encouraged, promoted, invested, implemented, and demonstrated, but especially for small Wind farm.
Keywords: wind speed and direction, Rayleigh probability density, power density, wind speed probability curve, Zeway.

Abstract: An extracellular beta amylase was induced in cultures of Bacillus subtilis isolated from the kolanut weevil, Balanogastris kolae grown in liquid medium that contained cocoyam starch as sole carbon source. The enzyme was partially purified by acid treatment with ice cold 1.0N HCl and gel filtration with Sephadex G 150. The enzyme had its optimal activity at pH 6.0 and exhibited maximal activity at temperature of 50oC. The activity of the enzyme was enhanced by Na+, while ethylene diaminetetraacetic acid (EDTA), Hg2+ and Ca2+ acted as mild inhibitors and Fe2+ was a strong inhibitor of its activity. The beta amylase had a molecular weight of 27.6 kDa and an apparent Michaelis constant Km of 4.6 mg/ml and maximum velocity (Vmax) of 47.62 U/mg proteins.
Keywords: cocoyam, starch, inhibitors, molecular weight, kolanut weevil

Abstract: Historic wells (boudies) built by Adil Shahi dynasty in Bijapur, are huge sources of water in drought area, presently neglected and polluted.The two wells Taj boudi and Chand boudi were selected to study the depth wise water quality physio-chemical, phytoplankton, and bacteriological study. In Taj Boudi exceptional vertical inverse thermal stratification was observed and in Chand Boudi homothermal condition was noted. The input of medical wastes in Chand Boudi, led to the release of biochemical parameters like creatinine, protein, glucose, urea and uric acid with the increase of E-coli. As a result, floating meadow formed by the mud and plaster of paris (idol material) has the growth of macrophytes which are nourished by the organic biochemical compounds decomposed by the bacterial activity which acts as manure for the macrophytes. The selfpurification of water takes place naturally as quality condition. Chlorides, nitrogenous content and carbon dioxide in the wells are high indicating rich nutritional status. There is natural symmetry expressed in the wells in the seasonal changes to the bacterio plankton and phyto plankton of water. Algal maxima were observed soon after which bacteria were in excess in Chand Boudi.
Keywords: Boudies, Natural Symmetry, Physico chemical, Phyto plankton, Thermal stratification
