The development of peptide-based inhibitors of the low affinity Fc receptor, Fc [gamma] RIIa
FcyRIIa is an activatory receptor and contains an immunoreceptor tyrosine-based activation motif (ITAM) in its cytoplasmic domain, involved in the initiation of signalling events. There is now strong evidence from transgenic mouse models and human genetic susceptibility studies that implicate …

Installation and evaluation of domestic greywater reuse systems
This study focuses on the installation and evaluation of domestic greywater reuse systems. The project was undertaken to assess the feasibility of reusing domestic greywater for irrigating lawns/gardens and for flushing toilets, to determine potential health and environmental impacts of such reuse, …

Evolutionary structural optimization method for systems with stiffness and displacement constraints
This thesis presents the development of an evolutionary method for optimization of stmctures subject to displacement and stiffness constraints. Using an optimality criteria approach, the study provides a rigorous mathematical basis to the recently proposed evolutionary stmctural optimization (ESO) …

Heat transfer and condensation of water vapour from humid air in compact heat exchangers
In this thesis, an experimental and simulation study of heat transfer in water-to-air compact-plate heat exchanger is presented. A compact-plate heat exchanger made of polypropylene, in which flow pattern is maintained as counter-current, was constructed to conduct the experiments. Experiments were …

Optical fibre surface plasmon resonance sensors based on a metallic array of sub-wavelength apertures
… resonance sensors based on a metallic array of sub-wavelength apertures are investigated. Metallic sub-wavelength apertures may be designed to support surface plasmon resonances that are sensitive to the surrounding environment when embedded at the end-face of an optical fibre. Factors …

Hybrid organic-inorganic pervaporation membranes for desalination
… using reverse osmosis (RO) has been the leading candidate technology for supplying fresh water in recent years. However, there is a strong motivation for improving the established membrane process and/or developing alternative membrane technologies to overcome the limitations of high energy cost …

Interference mitigation in colocated wireless systems
The placement of base station transceivers at close proximity to one another is a major challenge for RF engineers. In a colocated setting, the base station receivers have to receive weak desired signals in the presence of high-power transmit/jamming signals from colocated base station …

Nonlinear inelastic analysis of concrete-filled steel tubular slender beam-columns
… (CFST) slender beam-columns may undergo local and global buckling when subjected to biaxial loads, preloads or cyclic loading. The local buckling effects of steel tube walls under stress gradients have not been considered in existing numerical models for CFST slender beam-columns. This thesis …

The selective separation and extraction of metals using membrane technology
The separation of Co(II), Ni(II) , Fe(II) and Fe(III) has been a problem that has vexed chemists for many years. Separation has been difficult because of the very similar chemical properties of these transition metals that are situated alongside each other in the Periodic Table. The work contained …

Test burning of carpet and foam and potential interferences in identifying petrol in arson investigation by gas chromatography/ mass spectrometry
… described in this thesis contains the results of the study on subjecting carpet and foam to different burning tests and the evaluation, by gas chromatography/ mass spectrometry (GC/MS), of the burnt residues for the purpose of identifying compounds which may potentially interfere with the …

Flow fields and heat transfer of liquid falling film on horizontal cylinders
… liquid film flowing over horizontal cylinders is of great importance as a high rate of heat transfer exists between the falling liquid film and the horizontal cylinders. The objective of this research is to use numerical predictions, following experimental verification, to study the flow field and …

Incorporation of natural antimicrobial agents into starch-based material for food packaging
Antimicrobial (AM) films comprising of thermoplastic starch (TPS) and a commercial aliphatic polyester blended with thermoplastic starch (APTPS) were prepared and their properties, release of AM agents, and AM efficacy was studied in laboratory media and on a real foodstuff (Cheddar cheese). The AM …

Graphic user interface modelling and testing automation
… ACM Computing Surveys, on average, more than 45% of software code in a software application is dedicated to the GUI. However, GUI testing is extremely expensive. In unit testing, 10,000 cases can often be automatically tested within a minute whereas, in GUI testing, 10,000 simple GUI test cases …

Sources, distribution and speciation of aluminium in wine production
The bioavailability and toxicity of aluminium in humans resulting from dietary intake, including beverages such as wine, has been of political concern over the last 20 years. In order to ascertain its potential bioavailability and toxicity from a dietary source such aa wine a full knowledge of the …
