  • Analysis and Assessment of Agulu-Nnaka Erosion Impact on Human Lives and Infrastructure

    Analysis and Assessment of Agulu-Nnaka Erosion Impact on Human Lives and Infrastructure OTTI, V. I and EKENTA, D. E Civil Engineering Department,Nnamdi Azikiwe University,Awka The aim of this study was to rehabilitate the gully erosion site and reduce longer term erosion vulnerability in Agulu/Nanka Community. This activity was carried out through some civil works such as construction of concrete drainage system, culverts and silty basin, spikes, rock chutes and stabilization of gully. An engineering design was used for the erosion…

  • Tribo evaluation of Surface Treated Carbon Fiber Reinforced Friction Material

    Tribo evaluation of Surface Treated Carbon Fiber Reinforced Friction Material Naresh Kumar Konada 1*, K.N.S.Suman 2 1* Department of Mechanical Engineering , Anits Engineering College,Visakhapatnam, INDIA 2 Department of Mechanical Engineering , Andhra University College of Engineering,Visakhapatnam, INDIA Carbon fiber reinforced friction material is formulated by grafting MWCNT-F on its surface. This material combination is investigated in this work by using a wear test apparatus. The surface of CF is chemically inert and hydrophobic in nature and possesses poor bonding…

  • Thin Film Diamond For Optical Applications

    Thin Film Diamond For Optical Applications Mohammad Abdul Razak1 and Sheikh Irfan Samad1 1College of electrical engineering, Universiti Malaya, Malaysia Diamond is a unique material with robust mechanical properties, the electrical and the optical properties of the thin film diamond can be altered as they are deposited using microwave plasma enhanced chemical vapor deposition (MPCVD) method. The thin film diamond can be used both as optical window for certain wavelengths of light and as a reflector, based on the thickness…

  • Comparative Analysis of Collapse Loads of Slabs Supported on Orthogonal Sided Frames with Beam/ Column Joint Fixed

    Comparative Analysis of Collapse Loads of Slabs Supported on Orthogonal Sided Frames with Beam/ Column Joint Fixed S.O. Osuji, L.O. Adhekoyibo University of Benin Department of Civil Engineering Benin City, Edo State, Nigeria. This research work evaluates the collapse loads of slab supported on orthogonal side ended frames with column/beam joint fixed. Two frame models were investigated (one with Moment of Resistance of slab (MRS) > Moment of Resistance of beam (MRB) and the other with Moment of Resistance of…
