Author:Khuluse, S; Stein, A; Debba, PraveshDate:Mar 2011Early development of Extreme Value Theory (EVT) was motivated by a need to quantify the probability of unusually large (or small) events in hydrology and climatology. The current challenge in modelling extremes is how to adequately account ...Read more
Author:Hodgskiss, J; Zschernack, SDate:Jul 2013The purpose of this study was to examine differences in muscular activation between males and females while walking in restricted postures. Restricted postures are evident in various industries, including mining, construction and agriculture. ...Read more
Author:Van Zyl-Bulitta, VH; Ritzel, C; Stafford, William HL; Wong, JGDate:Aug 2019The global energy transition is characterised by a myriad of technology options, organisational forms and infrastructural scales across levels of operation. Energy transitions are generally considered to foster sustainable development. However, ...Read more
Author:Moolman, FS; Meunier, M; Labuschagne, Philip W; Truter, PADate:25 Jul 2005The CSIR has developed a novel oxygen barrier technology for plastics packaging based on interpolymer complex formation between PVOH (polyvinyl alcohol) and PMVE-MA (poly(methyl vinyl ether-co-maleic acid)). As interpolymer complexation ...Read more
Author:Ojijo, Vincent O; Kesavan Pillai, SreejaraniDate:2020Solid-state shear pulverization (SSSP) is a relatively new high-pressure and shear deformation technique, which relies on mechanochemical reactions between polymer chains in solid state. One of it applications is in the compatibilization of ...Read more
