The identification of regulatory Elements in pseudomonas aeruginosa and p. putida responsive to specific heavy metals.
(University of Western Cape, 1999)
Heavy metals constitute a group of about sixty-five elements having a density greater
than five (Gadd and Griffiths, 1978). Some metals, for example lead, copper, and nickel
are extremely precious and profitable to man ...
The adenomatous polyposis coli (APC) and p53 gene status in South African oesophageal cancer patients
(University of the Western Cape, 1996)
Oesophageal cancer is the most conmon cause of cancer-related deaths in black males in South Africa. In an effort to understand the molecular nature of oesophageal carcinogenesis in South Africa, two tumour suppressor ...
Singular integral equations and realization: A survey of the state space method
(University of the Western Cape, 1996)
Different methods for solving singular integral equations exist. One of the most recent methods is the so-called state space method. This method is based on the fact that a rational matrix function VV(^) which is analytic ...
The effects of clipping and burning on the allocation of total nonstructural carbohydrates and selected mineral nutrients in Imperata cylindrica (L.) Raeuschel
(University of the Western Cape, 1999)
The rhizomatous grass, Imperata cylindrica, occurs in the Cape Flats Nature Reserve (CFNR), South Africa. It is recognised globally as a weed of crop plants. The response of this weed to defoliation, in the forms of clipping ...
Computation of the character tables of certain group extensions
(University of the Western Cape, 1997)
In this chapter some basic theory on group extensions is first given in section 1.1 and then a method for finding the conjugacy classes of group extensions is described in section i.2. In section 1.3 we look at an example ...
The influence of maternal nicotine exposure on neonatal lung development: An enzymatic and metabolic study
(University of the Western Cape, 1999)
Chapter I, the literature review, gives the reader a sound background knowledge of the following: normal lung structural development in humans and rats, metabolic development with reference to structural development, tobacco ...
Effect of simulated acid rain on seed germination and on growth and mineral nutrition of Lycopersicon esculentum var. Red kaki
(University of the Western Cape, 1993)
The phenomenon of acid rain is not new. It has been active for more than a billion years (Abelson, 1983). The term "acid rain" was introduced as early as 1872 by Robert Angus Smith, the world's first air pollution control ...
The antimicrobial screening of four South African Asteraceae species and the preliminary structural investigation of an antipseudomonal compound from Arctotis auriculata
(University of the Western Cape, 1998)
Infectious diseases represent one of the main causes of morbidity and mortality in developing countries, like South Africa. The indiscriminate use of antibiotics has also resulted in the emergence of a number of resistant ...
Effect of inhaled cationic poly-peptides on respiratory mechanics in the isolated perfused rat lung
(University of the Western Cape, 1998)
The inhalation route is increasingly being considered as a viable option to deliver protein drugs into the body, but there has been few studies dealing with the safety of this strategy. The results of in vitro studies have ...
