Abstract:

Ice streams are the dominant drainage pathways of contemporary ice sheets and their location and behaviour are viewed as key controls on ice sheet stability. Identifying palaeo-ice streams is of paramount importance if we are to produce accurate reconstructions of former ice sheets and examine their critical role in the oceanclimate system. Many workers have invoked palaeo-ice streams from a variety of former ice sheets, despite a limited understanding of their glacial geomorphology. This thesis addresses the problem by predicting several diagnostic geomorphological criteria indicative of ice

Abstract:

In this thesis the effect of uniform and profiled (non-uniform) steady flows on a scale-model tidal stream turbine (0.5m diameter) are experimentally investigated using the University of Liverpool high-speed recirculating water-channel. The power and thrust coefficients of the turbine with numbers of blades between two and six and various blade-pitch-angles are measured in uniform flow with low levels of turbulence at velocities ranging from 0.45m/s to 1.34m/s. With a three-bladed turbine at optimum blade-pitch-angle the power and thrust coefficients are compared in three different flow condit

Abstract:

North Pakistan represents a highly favourable area for a variety of mineral deposit types, including arc-related porphyry Cu, Au and Mo and arc and backarc epithermal precious metal deposits (Sweatman et al., 1995; PMDC, 2001). However, few deposits have been discovered in the area, mainly due to its remote nature and inaccessibility, and because of a lack of exploration tools for high altitude terrains. From stream sediment sampling campaigns by local and international organizations, including a large dataset provided by the Pakistan Mineral Development Corporation (PMDC), a significant amoun

Abstract:

The mechanisms underlying stretch-induced signalling in the human myometrium are poorly understood. Previous work in the group has demonstrated that in vitro stretch of human myometrial cells leads to increased expression of the pro-labour factors COX-2 and IL-8 via activation of the ERK-1/2 MAPK cascade, however the identities of components upstream in this pathway have yet to be elucidated. I over expressed constitutively active Ras in human myometrial cells, leading to increased ERK-1/2 phosphorylation and elevated COX-2 and IL-8 mRNA expression. I then inhibited Ras using both the chemical

Abstract:

Sugarcane bacilliform virus (SCBV) is an economically important pathogen of sugarcane in Australia which limits access to foreign sugarcane germplasm. Although SCBV is present in the major cane growing regions worldwide, very little is known about its variability, virulence and the yield losses resulting from infection. The limited information on SCBV has resulted in quarantine measures being introduced to protect the Australian sugarcane industry, with a major consequence being restricted access to imported sugarcane germplasm for breeding programs.

Abstract:

Thesis (PhD (Physics))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: Ultrafast Electron Diffraction (UED) is a rapidly maturing field which allows investigation of the evolution of atomic arrangement in solids on timescales comparable to the vibrational period of their constituent atoms (~10-13 s). The technique is an amalgamation of conventional high energy electron diffraction methods and pump-probe spectroscopy with femtosecond (1 fs = 10-15 s) laser pulses. Ultrafast pulsed electron sources generally suffer from limitations on the attainable electron number per pulse (bright

Abstract:

Residual stresses are the stresses which are present within a component without any external load. They can be introduced through any number of manufacturing processes and in-service conditions, meaning that they are almost ubiquitous in engineering components. The characterisation of residual stress is an important field of research particularly in an engineering context since the effects of residual stress sum with the loads. As a result, the performance of a component can be greatly enhanced, or significantly reduced, by the presence of residual stress depending on the sign of the stress an

Abstract:

This research has investigated the conditions necessary for atmospheric-induced stress corrosion cracking to occur in material taken from an intermediate level nuclear waste storage container by means of experiments in a humidity chamber. It has also characterised the residual stresses associated with the container welds by modelling and measurement. Based on the work conducted in this research, the major findings can be summarised as follows:• Deliquescence of salt particles is dependent on relative humidity but independent of the quantity of salt present.• The time to initiate cracking may b

Abstract:

This practice-led novel and exegesis explores the characterisation of an anecdotal 1980s Wall Street junket on Queensland's Gold Coast in terms of Foucauldian power and discourse. Problematising the subject's decentred ontology implied by the life sciences, Foucault's theories are adapted to illustrate characterisation as a site of discursive interpellation and contest in neoliberal fiction. Decentred, the subject as a scape of discursive practice reveals the struggle between 'personal discourse' and the organisational power of corporations. This has implications not only for character intenti

Abstract:

The interest in studying droplet related phenomena has been increasing over the last decades. In the fluid dispensing equipment industry, a major problem is to minimise droplet diameter and to eject droplets in a controlled manner with a low-cost device. Micro-droplet generation has gained its popularity for its multiple applications, such as biotechnology, manufacturing engineering, and fuel dispensing. Taking all this into account, a new low-cost droplet stream generator was designed and fabricated. The material used to manufacture the stream droplet generator structure was PLA, since it is

Abstract:

Maize is the staple food for a majority of people in Southern Africa, but plant diseases are responsible for at least 10% of crop production losses. Bacterial leaf streak (BLS) of maize was first reported in South Africa in 1949 and has not been reported elsewhere. Very little is known about the pathogen involved and therefore it is deemed necessary to compile a characteristic profile for the pathogen to prevent the possibility of major crop losses as a result of this disease. This study aimed to use biochemical and phenotypic methods to determine the specific characteristics of the causal age

Abstract:

All members of the genus Xanthomonas are considered to be plant pathogenic, with specific pathovars infecting several high value agricultural crops. One of these pathovars, X. campestris pv. zeae (as this is only a proposed name it will further on be referred to as Xanthomonas BLSD) the causal agent of bacterial leaf steak of maize, has established itself as a widespread significant maize pathogen within South Africa. Insufficient information about the present distribution of the pathogen is available. The main aim of the study was thus to isolate and characterise the pathogen using molecular
