  • Chemical absorption of carbon dioxide in Biogas Purification 
    Maile, O.M.; Muzenda, E.; Tesfagiorgis, H. (Elsevier B.V., 2017-01)
    Biogas is produced from anaerobic digestion of organic biodegradable materials. However, its application is limited as it contains impurities such as carbon dioxide (CO2), hydrogen sulphide (H2S), and other trace gases. ...
  • Diffusion in Saturated Clayey Barrier Medium 
    Agbenyeku, E.E.; Muzenda, E.; Msibi, M.I. (Elsevier B.V., 2017)
    The design of clay/clayey barriers for the containment of buried wastes conventionally has been based on the assumption that the hydraulic conductivity controls the rate of leachate percolation. However, recent studies ...
  • Liner-leachate interaction curve models for clayey soils from landfills around the city of Johannesburg 
    Agbenyeku, Emem-Obong Emmanuel; Muzenda, Edison; Msibi, Mandla Innocent (Federal University of Technology, Minna, Nigeria, 2017)
    The study presented herein links to a regression analysis that ties into three mathematical models from the Brutsaert, Mualem and Burdine equations respectively. The paper describes a series of experimental investigations ...
  • Software controlled stepping valve system for a modern car engine 
    Zibani, I; Marumo, R; Chuma, Joseph; Ngebani, I (Elsevier B.V., 2017-10)
    To address the problem of a piston-valve collision associated with poppet valve engines, we replaced the conventional poppet valve with a solenoid operated stepping valve whose motion is perpendicular to that of the piston. ...
