Author:Chunilall, Viren; Bush, T; Larsson, PTDate:Aug 2013In chemical pulping the components that keep wood cells together, mainly lignin are degraded and dissolved in order to obtain fibres for the dissolving pulp and paper processes. The aqueous solutions of pulping chemicals are transferred from ...Read more
Author:Labuschagne, W; Heidema, J; Britz, KDate:Dec 2013We explore a family of supraclassical consequence relations obtained by varying the criteria according to which counterexamples to classical entailment may be deemed tolerable. This provides a different perspective on the rational consequence ...Read more

Author:Chetty, AS; Seynberg, TJ; Moolman, FS; Nilen, RWN; Joubert, AM; Richter, PWDate:Feb 2006Polyurethane (PU) may be suitable for various implant applications; however, it lacks bioactivity. Bioactivity allows for direct tissue attachment at the bio- interface, enabling implant fixation while preventing fibrous encapsulation. To ...Read more
Author:Fernandes, PJL; McDuling, GADate:Jun 1997Surface contact fatigue is the most common cause of gear failure. It results in damage to contacting surfaces which can significantly reduce the load-carrying capacity of components, and may ultimately lead to complete failure of a gear. Three ...Read more
