In nineteenth-century Upper Canada (Ontario), professional work was a primary means by which men could improve their social status and class position. As increasing numbers of men sought entry into these learned occupations, current practitioners sought new ways of securing prominent positions in their chosen professions and asserting themselves as having expertise. This dissertation studies the activities and experiences of the five physicians who, as the first medical superintendents (head physicians) at the Provincial Lunatic Asylum, Toronto from 1840 to 1865, sought such enhanced professional status. Opened in January 1841 as a public welfare institution, the Toronto asylum was housed initially in a former jail; in 1850 it was relocated to a permanent building on Queen Street West. During the asylum’s first twenty-five years of operation physicians Drs. William Rees, Walter Telfer, George Hamilton Park, John Scott, and Joseph Workman successively held the position of medical superintendent at the institution. Given the often insecure status of physicians working in private practice, these doctors hoped that government employment at the asylum would bring greater stability and prestige by establishing them as experts in the treatment of insanity. Yet professional growth in Upper Canada during the Union period (1840-1867) occurred within the context of the colony’s rapidly changing socio-political culture and processes of state development, factors that contributed to the ability of these doctors to “professionalize” as medical superintendents. Rees, Telfer, Park, and Scott would never realize enhanced status largely due to the constraints of Upper Canada’s Georgian social culture in the 1840s and early 1850s. During the 1850s, however, demographic, political, and religious changes in the colony brought about a cultural transition, introducing social values that were more characteristically Victorian. For Joseph Workman, whose beliefs more reflected the new Victorian culture, this cultural shift initially involved him in professional conflicts brought about by the social tensions occurring as part of the transition. Nevertheless, by the 1860s, changes in government led to the development of new legislation and departmentalization of welfare and the public service that led him to gain recognition as a medical expert in a unique field.

The human upper airway structure provides access of ambient air to the lower respiratory tract, and it as an efficient filter to cleanse inspired air of dust bacteria, and other environmental pollutants. When air passes through airway passages, it constantly changes direction, which may lead to flow separation, recirculation, secondary flow and shear stress variations along the airway surface. Therefore, it is essential to understanding the air transport processes within the upper airway system. The functions are respiratory defence mechanisms that protecting the delicate tissues of the lower airway from the often harsh conditions of the ambient air. While protecting the lower respiratory system, however, the upper airway itself becomes susceptible to various lesions and infections from filtration of environmental pollutants. Inhaled particle pollutants have been implicated as a potential cause of respiratory diseases. In contrast, inhalation of drug particles de posited directly to the lung periphery results in rapid absorption across bronchopulmonary mucosal membranes and reduction of the adverse reactions in the therapy of asthma and other respiratory disorders. For this purpose, it is desirable that the particles should not deposit in the upper airways before reaching the lung periphery. Therefore, accurate prediction of local and regional pattern of inhaled particle deposition in the human upper airway should provide useful information to clinical researchers in assessing the pathogenic potential and possibly lead to innovation in inhalation therapies. With the development of the increasing computer power and advancement of modeling software, computational fluid dynamics (CFD) technique to study dilute gas-particle flow problems is gradually becoming an attractive investigative tool. This research will provide a more complete picture of the detailed physical processes within the human upper airway system. Owing to the significant advancements in computer technologies, it will allow us to efficiently construct a full-scaled model integrating the various functional biological elements including the nasal, oral, laryngeal and more generations of the bifurcation of the human upper airway system through imagining methodologies. A significant advantage of this human model is that the differences in airway morphology and ventilation parameters that exist between healthy and diseased airways, and other factors, can be accommodated. This model will provide extensive experimental and numerical studies to probe significant insights to the particle deposition characte ristics within the complex airway passages and better understanding of any important phenomena associated with the fluid-particle flow. It will also lead to an improved understanding of fluid/particle transport under realistic physiological conditions. New concepts and numerical models to capture the main features observed in the experimental program and innovative techniques will be formulated. The ability to numerically model and a better physical understanding of the complex phenomena associated with the fluid dynamics and biological processes will be one of the major medical contributions especially targeting drug delivery and health risk analysis. Its biomedical engineering significance lies in the fact that this will enable us to accurately evaluate potential biological effects by the inhaled drug particles, facilitating new drug research and development.

Abstract This thesis examines the raison d�etre of the Australian Senate, the upper house of the Australian bicameral parliament, established in 1901. It explores the literature that might have influenced its establishment and structure, and the attitudes, ideals, experience and expectations of the men (and they were all men) who initiated its existence and designed its structure during the Federation Conventions of the 1890s. It goes on to study whether similar western and British influenced institutions were seen as models by the designers of the Senate, followed by an examination of its architecture, d�cor, and procedures, to determine the major influences at work on these aspects of the institution. The study was undertaken in view of the paucity of studies of the history and role of the Senate in relation to its powerful influence on the Government of Australia. Its structure can allow a minority of Senators to subvert or obstruct key measures passed by the lower house and is a serious issue for Governments in considering legislation. Answers are sought to the questions of how and why it was conceived and created and what role it was expected to play. The study does not extend beyond 1901 when the Senate was established except to examine the Provisional Parliament House, opened in 1927, which realised the vision of the Convention delegates who determined that the Senate was the house we had to have. The research approach began with an exhaustive study of the Records of the Federal Conventions of the 1890s, where the Constitution of Australia was drawn up, along with contemporary writings and modern comment on such institutions. A study of the men who designed the Senate was carried out, augmented with field visits to the Australian State Parliaments. Research was also conducted into upper houses identified by the delegates to the Australian Federal Conventions, to consider their influence on the design of the Senate. The conclusion is that the Senate was deliberately structured to emulate the then existing British system as far as possible; it was to be an august house of review and a bastion against democracy, or at least a check on hasty legislation. The delegates showed no desire to extinguish ties with Great Britain and their vision of an upper house was modelled directly on the House of Lords. The vast majority of delegates had cut their teeth in colonial upper houses, which were themselves closely modelled on the Lords. To not establish a Senate would have been to turn their backs on themselves. The Senate then, is not a hybrid of Washington and Westminster: the influence of the United States was limited to the composition of the Senate and its name and mediated through the filter of its British heritage. The example of other legislatures was unimportant except where it solved problems previously experienced in the Colonial Councils and which might have otherwise occurred in the Senate. The Senate was the upper house we had to have; it was a decision that was taken before the delegates even met.

The intermontane Mackenzie Basin is located within the central South Island of New Zealand. The glacial basin contains three glacial lakes which are used for hydroelectric power generation via a canal system that links the lakes. The basin is an area of climate extremes, low rainfall, high summer temperatures, and snowy winters. The area is predominantly used for pastoral farming, however farming practices are changing and, combined with an increasing population, there is a need to define the groundwater resources to enable sustainable resource management. Little is currently known about the hydrogeological system within the Mackenzie Basin, and what is known is from investigations carried out during the construction of the canal system from 1935 to 1985. There are four glacial formations that overlie Tertiary sequences and Torlesse bedrock. However, due to the glacial processes that have been ongoing over at least the last 300 ka, determining the occurrence and extent of groundwater within the outwash gravels is difficult. It is suggested that the permeability of the formations decreases with depth, therefore horizontal and vertical hydraulic conductivity decrease with depth. A shallow groundwater table is present within the Post Glacial Alluvial Gravels which is recharged directly from fast flowing streams and rivers as well as rainfall. It appears that this shallow system moves rapidly through the system and it is unlikely that the water infiltrates downwards to recharge the deeper groundwater system. It is thought that a deep groundwater system flows preferentially through the Mt John Outwash Gravels, being the second youngest glacial formation. Water chemistry and age dating tracer analysis indicate that the deeper groundwater is over 80 years old and that the groundwater system is recharging slowly. The shallow groundwater in the Post Glacial Alluvial Gravels and within the major fans to the east of the basin is 10 to 20 years in age. Baseline data such as water chemistry, groundwater levels, and surface water gaugings have been collected which can be used for future investigations. More data needs to be collected to create a long term record to further define the hydrogeological system and to determine the best way to manage the resource for long term sustainable use in the future.
