- 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
- Authors: Marsh, Julian S

- 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.

The commercial agricultural economy of the East Cape: Die kommersiële landbou-ekonomie van die Oos-Kaap
- Authors: Antrobus, Geoffrey G
- Date: 2010
- Language: English
- Type: text , article
- Identifier: http://hdl.handle.net/10962/143079 , vital:38199 , DOI: 10.1080/03031853.1991.9524228
- Description: The East Cape, and in particular the Smaldeel area, is used to exemplify some of the characteristics and problems of commercial farming over a period of about three decades to serve as a backdrop for the broader theme of normalising South African agriculture. The regional economy is dominated by Port Elizabeth-Uitenhage and East London which account for most of the population and three-fourths of the Gross Geographic Product (GGP). Agriculture accounts for only 10% of GGP, but is one of the most labour intensive sectors in a region with 24% of its population unemployed. The agricultural economy of the region is very diversified, but livestock farming plays the most important part in all areas contributing 72% of gross income. The chief changes which have occured in East Cape farming, as elsewhere, have been the decline in the number of farms and increase in farm size, greater capital investment, increased specialisation and declining employment.
