Author:Ramduth, DM; Lalloo, Rajesh; Zulu, NNDate:Feb 2006A biological treatment, containing a consortium of Bacillus species isolated from natural environments, was formulated into a prototype product. Experiments were aimed at demonstrating the effects of the prototype on water quality. Trials ...Read more
Author:Jonathan, EDate:Jan 2008While human sweat secretion is accepted as a mechanism by which the body cools off, excessive sweating (hyperhidrosis) is now appreciated
as a medical condition and the primary site for diagnosis is the palm of the hand. We propose sweat ...Read more
Author:Van Schoor, Michael; Binley, ADate:Dec 2009The applicability of tunnel-to-tunnel electrical resistance tomography (ERT) for imaging disruptive geological structures ahead of mining, in an igneous platinum mining environment is assessed. The geophysical targets of interest are slump ...Read more
Author:Van Schoor, MichaelDate:Sep 2006One of the strengths of the electrical resistance tomography (ERT) technique is its flexibility in terms of survey geometries. In this paper an unconventional and novel ERT application that is geometrically analogous to in-seam seismic ...Read more
Author:Tlotleng, Monnamme; Pityana, Sisa LDate:Nov 2017Titanium aluminides (TiAl) are interesting intermetallic materials to study due to their enhanced high temperature and light weight properties. They are necessary as structural materials, but brittle to form with conventional methods. Hence ...Read more
Author:Van Rooyen, Corney; Burger, H; Theron, Maritha; Doubell, PDate:Sep 2010Laser cladding crack repair of austenitic stainless steel vessels subjected to internal water pressure was evaluated. The purpose of this investigation was to develop process parameters for in-situ repair of through-wall cracks in components ...Read more
Author:Motsi, G; Olumbani, PA; Sono, T; Shoke, LDate:Oct 2014In this study tensile deformation mechanisms of aluminium alloy 5083 were investigated under observations made from SEM equipped with a tensile stage. Observations during tensile testing revealed a sequence of surface deformation events. These ...Read more
Author:Popoola, API; Phume, L; Pityana, Sisa L; Aigbodion, VSDate:Jan 2016Ti6Al4V alloy has been widely used for medical implants due to good mechanical properties. For permanent implant applications Ti6Al4V alloy has shown to have low corrosion and wear resistance. Based on these the development of in-situ Ti6Al4V–TiB ...Read more
Author:Phume, L; Popoola, API; Aigbodion, VS; Pityana, Sisa LDate:2018Ti-6Al-4V alloy biomaterials have low hardness, wear resistance, high corrosion rate and toxicity as results of release of aluminium and vanadium ions that led to the premature failure of the implant. In order to overcome some of these problem ...Read more
Author:Raji, SA; Popoola, API; Pityana, Sisa L; Popoola, OM; Raji, NK; Tlotleng, MonnammeDate:Feb 2022Gamma titanium aluminide ( -TiAl) alloys are lightweight materials with potential application for high-temperature components. But their ductility at room temperature impedes widespread production of parts via traditional processing routes. ...Read more
