Die invloed van verdamping op die segregasieproses

Measuring the effect of surface evaporation on the segregation process. Metallurgical products play an important role in everyday life. One process, by means of which metallurgical properties can be determined, is known as segregation. The influence of surface evaporation should be considered in order to improve segregation studies. Modifications made to an Auger system in order to measure surface evaporation that takes place during segregation are discussed.

The aim o f this article is to expose a dichotomy between the inter-and intrapersonal aspects o f sexuality that haunt the current discourse on sexual normality. This division has led to a dual movement: in one direction to a moral relativism and in the other to an exclusive focus on sexual instincts. Thus, in the current discourse on sexuality, the interper sonal dimension o f sexuality is underplayed, while the intrapersonal dimension is overemphasized. I argue instead fo r a bridging o f the gap between the inter-and intrapersonal dimensions o f sexuality. The reason: neither moral relativism nor a rigid deterministic structure fo r sexual instincts represents an adequate view of, on the one hand the description o f sexuality, and on the other the prescription o f the expression o f that sexuality. In conclusion, I point to a few consequenses o f the integration o f both dimensions fo r sexual normality.

This article is a demonstration o f the unbearable greenness o f theory. The first part explores the meaning o f green (in Afrikaans) as a demonstration o f what intertextuality means. The second part outlines the resistance to theory. Against this resistance it is argued that theory is engaged (inter alia) in reading and interpreting difficult texts and contributing to solving the universal problem o f interpretation. As an example the controversial singing o f "Die Stem" at a rugby test is analyzed. The third part argues for the fecundity o f theory by outlining the value o f narrative theory fo r other disciplines and by a literary analysis o f the science policy and the motto o f the PU fo r CHE and a love poem by B. Breytenbach. A short program matic view o f the future o f literary theory at the PU fo r CHE concludes the article.
