- Description: This paper gives an overview of the approach used for the assessment of several operating systems for microcomputers. The operating systems are all commercial products and cover a spectrum ranging from general purpose operating systems to small, real-time operating systems. The criteria used for the evaluation are discussed and the approach used is discussed in detail. The results of the evaluation are not discussed in this paper.

- Description: Poor compliance with prescribed medication is a significant problem in chronic disease states and is often responsible for the apparent failure of therapy. The determinants and extent of non-compliance are commonly incorrectly perceived by doctors. During routine therapeutic drug monitoring of epileptic and asthmatic outpatients at a local day hospital, non-compliance was identified as a significant problem. A compliance study was conducted on 80 epileptic and asthmatic patients to determine the nature and extent of this problem. Non-compliance was measured using four different methods, which were then compared using chi 2 tests.

REE fractionation and Ce anomalies in weathered Karoo dolerite

- Description: Analyses of samples from a weathering profile on Karoo dolerite allow elements to be divided into three groups depending on their behaviour. Si, K, Na, Mg, Ca, Sr, Ba and V are mobilized and removed from weathered products. Fe, Al. Ti, Zr, Hf, Zn, Cu, Sc, Co and Ni are immobile. REE, Y, and to a lesser extent Cr, are mobile and redistributed within the profile without a net loss of these elements from the profile. Large positive Ce anomalies are developed in oxidized weathered products by preferential leaching of the other REE's. Negative Ce anomalies and REE enrichment is a feature of less altered dolerite.
