"The primary purpose of this dissertation is to elucidate the mechanisms and sources of fluid contributing to exercise-induced hypervolemia. The second aim is to identify changes in blood volume regulation that act to retain this fluid in the vascular space. A final aim is to identify the mechanisms responsible for inducing training bradycardia".

"The thesis argues that reading and spelling are interdependent and complex processes, and that "good" readers. but "poor" spellers, read in ways which do not assist in their developing spelling repertoires: their reading behaviours contribute to overall text meanings wihout contributing to individual word knowledge. As well, their writing behaviours do not allow for this knowledge to be used, practised, or displayed."
Description:
An important industrial problem is the production of wastewater containing a large amount of heavy metal ions. The study described in this thesis is trying to use precipitate flotation technology to explore techniques for not only removing heavy metal ions from the solution, but also selectively separating them to recycle of the recoyered metal value from industry wastewater. Zinc and copper hydroxide precipitation and flotation behaviour have been studied. lt shows that it is almost impossible to separate copper and zinc ion using hydroxide precipitate flotation when the solution contains Fe3+ or Al3+ ions. The influence of additional ions such as Ca2+ and Mg2+, and other electrolytes on the flotation and separation have been studied. DLVO theory has been used to explain the mechanisms occurring in the process. A new process, named "self-carrier" precipitate flotation us~g anionic surfactants, has been developed to improve the flotation recovery and reduce the consumption of collector. The mechanism of the process is discussed in detail with reference to data collected from Optical Microscopy, Scanning Electron Microscopy and Zeta Potential Measurement. The xanthates are the most commonly used class of sulphide mineral collectors. This study investigated the copper sulphide precipitate reactions and the aggregation behaviour, the influence of oxidation, additional ions etc., and successfully used xanthate to float the sulphide precipitates. The mechanisms occurring in this process have been discussed. The investigation of the sulphide precipitate flotation behavior using a cationic collector has also been carried out to discover the possibility of copper and zinc separation. An important application of this study is the flotation and separation of copper and zinc ions from industry wastewater. The tailing wastewater from a mineral processing plant, Woodlawn Mines (N.S.W., Australia), which contains high concentrations of harmful heavy metal ions was used to test the flotation and separation of the heavy metal ions. Both xanthate and cationic collectors have been investigated for the flotation separation. Effective separation has been achieved .

Description:
The Rotary Holding Furnace (RHF) is used in combination with the Copper Isasmelt Furnace as a settling vessel. This study investigated the phenomenon of entrained copper losses into RHF slag. Research work was conducted by laboratory-scale flow modelling, and by plant sampling of the RHF at Mount Isa Mines Limited. Laboratory fold modelling was conducted to measure the residence time distribution of a simulated slag layer in a l;'0 -scale model of the RHF. A novel technique, involving a copper tracer dissolved in an organic solvent extractant solution, was used for these experiments. Plant trials complemented the laboratory work with a variety of slag sampling campaigns. Residence time tests were also attempted on the RHF slag. In combination, the laboratory and plant scale experimental work performed in this investigation helped to highlight some likely causes of entrained copper loss in the RHF. Laboratory cold modelling of the RHF suggests that the depth of the upper liquid layer is • likely to affect the fluid flow patterns, and therefore the residence time distribution expected of the layer. A stratification of the flow was prevalent in thick upper liquid layers, but absent when thin upper layers were used. A stagnant region within the upper layer0 0f the model was identified. The introduction of gas injection through porous plugs caused mixing within the upper liquid layer. Stable waves were produced at the liquid liquid interfate. ' .. Plant experiments were constrained by commercial operating schedules. Several parameters were investigated during two different periods of experimental work. Granulated slag sampling indicated a link between the duration of continuous slag discharge and the copper content of the slag. Evidence was found that suggests the presence of interfacial waves.

Description:
"This thesis presents a considered artistic statement about how I experience and how I strive to embody, my notion of reality through the process of painting and drawing. It considers the activity of the creation of reality through a synthesis of perceptual and conceptual functioning. The thesis proposes that when a painted surface is viewed, the marks on this plane are arranged by the mind of the viewer to form an image which becomes infused with meaning. The created visual structures, in this way, promote a formerly undiscovered, conceptual reality."

"The aim of this thesis was to investigate the process by which policy regarding the use of computers in the classroom was developed in a secondary school in a Victorian provincial city. It seeks to determine whether a policy determined at a State Education Department level may be redefined at a local school administrative level and the changes that may occur when that policy is implemented in the classroom"
