Conditional and unconditional nonlinear stability for convection induced by absorption of radiation in a porous medium (2004)
Journal Article

Convection induced by the selective absorption of radiation is investigated, for the case of an internal heat source that is modelled quadratically with respect to concentration. The growth rate for the linearised system is shown to be real, and a li...

Convection induced by the selective absorption of radiation for the Brinkman model (2004)
Journal Article

Convection induced by the selective absorption of radiation in a porous medium is studied analytically and numerically using the Brinkman model. Both linear instability analysis and nonlinear stability analysis are employed. The thresholds show excel...

Penetrative convection induced by the absorption of radiation with a nonlinear internal heat source (2004)
Journal Article

A model for convection induced by the selective absorption of radiation in a fluid layer is investigated. The concentration based internal heat source is modelled quadratically. A linear analysis and conditional nonlinear analysis are performed. Due... Read More about Penetrative convection induced by the absorption of radiation with a nonlinear internal heat source.

Voltammetric, chromatographic and mass spectral elucidation of the redox reactions of 1-hydroxypyrene occurring at a screen-printed carbon electrode (2004)
Journal Article

The electrochemical oxidation of 1-hydroxypyrene (1-OHP) has been studied at a screen-printed carbon electrode (SPCE), by cyclic voltammetry and bulk electrolysis. Cyclic voltammograms exhibited two quasi-reversible pairs of peaks (designated 1a′/1c...

Magnocellular mediated visual-spatial attention and reading ability (2004)
Journal Article

This study explores the relationship between attentional processing mediated by visual magnocellular (MC) processing and reading ability. Reading ability in a group of primary school children was compared to performance on a visual cued coherent moti...

Voltammetric behavior of Chlorophyll a at a screen-printed carbon electrode and its potential role as a biomarker for monitoring fecal contamination (2004)
Presentation / Conference Contribution

Direct cyclic voltammetric determination of Chlorophyll a (Chl a) at a screen-printed carbon electrode (SPCE) resulted in a single, irreversible anodic oxidation peak at Ep = +400 mV vs. Ag/AgCl. Electrochemical investigations revealed that Chl a was...

A novel method for rapidly diagnosing the causes of diarrhoea (2004)
Journal Article

Background: The microbiological diagnosis of infectious diarrhoea may take several days using conventional techniques. In order to determine whether flatus can be used to make a rapid diagnosis, the volatile organic compounds associated with diarrhoe...

The pig CYP2E1 promoter is activated by COUP-TF1 and HNF-1 and is inhibited by androstenone (2004)
Journal Article

Functional analysis of the pig cytochrome P4502E1 (CYP2E1) promoter identified two major activating elements. One corresponded to the hepatic nuclear factor 1 (HNF-1) consensus binding sequence at nucleotides -128/-98 and the other was located in the...

Development of an electrochemical assay for 2,6-dinitrotoluene, based on a screen-printed carbon electrode, and its potential application in bioanalysis, occupational and public health (2003)
Presentation / Conference Contribution

Screen-printed carbon electrodes (SPCEs) have been successfully exploited as disposable sensors for the measurement of 2,6-dinitrotoluene (2,6-DNT) using a stripping voltammetric method. Initial investigations were undertaken using cyclic voltammetry...

Topology: A novel method to describe branching patterns in Peronospora viciae colonies (2003)
Journal Article

Topology provides a novel means to describe branching patterns and has not been applied to fungal colonies previously. For any branched structure, various topologies are possible, and these lie between two extremes, a herringbone pattern (main axis w...

Site of intracellular expression of ß-catenin influences the outcome in sporadic colorectal cancer (2003)
Journal Article

Background: Stabilisation and nuclear translocation of beta-catenin are suggested to be the early events in the colorectal carcinogenesis. Nuclear accumulation of beta-catenin was associated with high-grade tumour and increased cell proliferation in...

The synthesis of novel 3-substituted pyrrole monomers possessing chiral side groups: A study of their chemical polymerisation and the assessment of their chiral discrimination properties (2003)
Journal Article

Novel 3-substituted pyrrole monomers possessing chiral side groups were synthesised. These compounds were successfully polymerised with ferric salts and the polymer materials fabricated into sensors. The sensors were found to elicit differential chan...

Rationalization of retention and overloading behavior of basic compounds in reversed-phase HPLC using low ionic strength buffers suitable for mass spectrometric detection (2003)
Journal Article

The retention and overloading behavior of some basic (and acidic) compounds has been studied on different RP-HPLC columns in buffers of varying ionic strength. Anomalous retention patterns of acids and bases were found on one phase in low-pH, volatil...
