    Vertical electrical sounding (VES) was carried out at Union Site Gidan kwano campus, Federal University of Technology, Minna, Nigeria. The objective is to delineate area suitable for structural development and soil corrosivity of the study area. Schlumberger electrode configuration was adopted with maximum current electrode spacing (AB/2) of 100 m. The profile separations was 100 m with inter vertical electrical soundings (VES) point spacing of 100 m. Total of sixty (60) vertical electrical soundings (VES) station were covered. The interpretation revealed three distinct geologic layers. These include topsoil with resistivity values range between 11.41 and 1009 ohm-m and thickness is relatively thin and ranges between 1 and 6 m. The weathered/fractured layer has resistivity values also ranges from 11 to 963 ohm-m with thickness ranges from 1 to 45 which indicate high degree of weathered/fracture and/or water saturation, The fresh basement has resistivity values that range between 12 and 2983 ohm-m. All the soundings are 3-layered and are characterised by A, H and Q curve types. Seventeen (17) VES station were delineated for high rise building having depths to fresh basement varying between 2 m to 5 m (where consolidated basement is shallow with high resistivity value). The corrosivity ratings of the study area shows that 13% is moderately corrosive, 8% is slightly corrosive and 79% suggest practically noncorrosive. The result reasonably provide information areas where high rise building can be sited and iron pipe can be laid in order to safeguard the hydrological setting of the area.

    ANALYSIS AND DESRIPTION OF THREESTAGES HEAR TREATMENT REQUIRED IN THE FIBRICATION OF ADJUSTABLE DIE(THREAD CUTTING TOOL)USING HIGH CARBON STEEL
    (AFRICAN JOURNAL O ENGINEERING RESERACH AND DEVELOPMENT, 2008) ADETONA, Adebayo Abbass
    The work sample high grade carbon steel for annealing before machining it into a cutting tool the resultant tool was quenched in red oil from a temperature of 800 degrees centigrade to room temperature and was tested for work ability
