    SECURITY MANAGEMENT: THE ENGINEERING PERSPECTIVE
    (IEC, 2015) H. U. Ogboo; A. Nasir; J. Y. Jiya; H. T. Abdulkarim
    Security management is a difficult task as everyone agrees that security is a problem. As such, this work aims at addressing the ever increasing security challenge confronting us as individuals from the engineering perspective. Throughout human history, engineering has driven the advance of civilization. This can be seen from the metallurgists who ended the Stone Age to the shipbuilders who united the world’s people through travels and trades; the past witnessed many marvels of engineering prowess. As civilization grew, it became pertinent that the world became confronted with the challenge of survival and relevance and hence, the desire not to be cut out from the basic necessities of life and existence gave rise to devices by humanity to remain relevance and hence, the field of engineering owes it a responsibility to the world to see that this issue is sorted out as usual as it has always provided respite to the world.

    Effect of Cutting Speed and Feed Rate on Tool Wear Rate and Surface Roughness in Lathe Turning Process
    (International Journal of Engineering Trends and Technology (IJETT), 2015) O. A. Olugboji; M. S. Abolarin; J. Y. Jiya; S. O. Popoola; C. K. Ajani
    Machining is a vital part of the production process in the manufacturing industries. Turing operation was carried out on the mild steel to produce shaft of various diameters. The conditions applied during the turning operation include varying the cutting speed and feed rate while keeping other cutting variables like depth of cut constant. The results affirms that an increase in the cutting speed causes a decrease in the tool life, increase in the feed rate also affects the surface finish obtained.

    Development of a Test Rig for the Determination of Headloss and Friction Factor of Polyvinyl Chloride (PVC) Pipes
    (Journal of Energy Technologies and Policy, 2016) N. A. Musa; J. Y. Jiya; T. K. Aderoju
    This paper reports the design, construction and performance evaluation of a test rig for determining the head loss and friction factor of PVC pipes of different diameters (13mm, 19mm and 25mm) transporting water. On performance evaluation, friction factors of 0.0121, 0.0396 , 0.0171 and head losses of 37.8mm, 25.2mm and 12.6mm for 13mm, 19mm, and 25mm diameter PVC pipes respectively were obtained. Keywords: Head loss, friction factor, PVC pipes, test rig, water
