  • Mafusire, C; Forbes, A (AOSIS OpenJournals, 2013-11)
    When the walls of an open-ended horizontal steel pipe are heated before the pipe is rotated along its axis, the exchange of the expelled heated air with the incoming cooler air, sucked in along the axis, results in a medium ...
  • Mafusire, C; Forbes, A; Snedden, Glen C; Michaelis, MM (Academy of Science of South Africa, 2008)
    The graded index (GRIN-like) medium generated by gas inside a heated steel pipe when rotated about its longitudinal axis has the ability to focus a laser beam. While the effective focal length of such a system has previously ...
