Manual for the determination of Effect size indices and Practical Significance
Sep 05, 2017 - Manual for the determination of Effect size indices and Practical Significance H. S. Steyn (jr) Preface In my work as a statistical consultant over the last twenty years I have found that there is a dire need to be able to make assertions concerning practical significance, particularly in Human sciences. This requirement…http://natural-sciences.nwu.ac.za/scs/manuals/roc-analysis
Manual for ROC analyses
Mar 06, 2017 - Manual for ROC analyses Preface This guide, which leans heavily on the book of Krzanowski & Hand (2009), was written in an attempt to make it easier for the researcher to understand the theory behind and methods of ROC analyses. It is further attempted to explain the calculation methods by way of examples. With these…http://natural-sciences.nwu.ac.za/crb/research-groups/christien-strydom

Aug 31, 2017 - South Africa has significant reserves of various naturally occurring resources. While some materials can be easily purified from these resources other separations are notoriously difficult. For example, Zircon, the most important source for Zr worldwide, always contains a few percent of Hf.

H2 Production
Jan 19, 2017 - In our group membrane based elctrolyzers are developed for the production of H2 using novel processes like the hybrid sulphur (HyS) process where the hydrogen is produced by the oxidation of SO2 in the presence of water forming H2SO4. Both new and existing membranes are screened for their suitability for this process in terms of…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/process-intensification
Process Intensification
Jan 19, 2017 - Based on past experience on in-house manufactured zeolite coated ceramic membranes, current research is continuing on the use of zeolites and zeolitic membranes combining their catalytic properties as well as their ability to act as molecular sieves. /sites/natural-sciences.nwu.ac.za/files/files/CRB/imagesSintering…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/gas-separation
Gas Separation
Jan 19, 2017 - While gas permeation studies form an intrinsic characterisation tool both for the inorganic as well as organic membranes for various applications, there are ongoing projects focussing specifically on the resolution of various perfluorinated compounds. These projects focus mainly on finding membrane based separation processes to replace…http://natural-sciences.nwu.ac.za/node/23941
