The study on dehydration of frozen saskatoon berries and the need for dried fruits has been strategically identified in the prairies. Our motivation was to find a suitable method for dehydration in order to extend saskatoon berry shelf life for preservation. Microwave, convection and microwave-convection combination drying processes were identified to finish-dry saskatoon berries after osmotic dehydration using sucrose and high fructose corn syrup (HFCS) sugar solutions. Osmotic dehydration removes moisture in small quantities and also introduces solutes into the fruit that acts as a preservative and also reduces the total drying time. <p>Due to the very short harvesting season of saskatoon berries, an accelerated process like microwave combination drying can bring down the moisture to safe storage level, immediately after harvest. Untreated and osmotically dehydrated berries were subjected to convection (control), microwave and microwave-convection combination drying conditions at different product drying temperatures (60, 70 and 80C) until final moisture content was 25% dry basis. A laboratory-scale microwave combination dryer was developed, built with temperature and moisture loss data acquisition systems using LabView 6i software. Thin-layer cross flow dryer was used for convection-only drying and for comparison. <p>Drying kinetics of the drying processes were studied and curve fitting with five empirical equations including Page equation, was carried to determine drying constant, R2 and standard error values. The microwave-combination drying method proved to be the best for drying saskatoon berries. Dehydrated product quality analysis by means of color changes, rehydration ratio measurements and observed structural changes with scanning electron microscope technique were the factors in drying method selection for saskatoon berries.<p> This research was instrumental in the modification and development of a novel drying system for high-moisture agricultural materials. Microwave-convection combination drying at 70oC, yields good results with higher drying rates and better end-product quality.

The steel through-truss Traffic Bridge, located in Saskatoon, Saskatchewan is over one hundred years old. The bridge has been subject to ongoing maintenance throughout its service life. However, inspection reports from 2005 and 2006 highlighted the severe deterioration experienced primarily by the steel members immediately above and below the deck surface. These reports prompted the City of Saskatoon (COS) to implement a rehabilitation project that involved the installation of a post-tensioning system to relieve the badly corroded bottom chord members of the axial loads due to the self-weight of the structure, in 2006. Due to the severe deterioration and the structural modifications that the Traffic Bridge has endured, a limited scope structural health monitoring (SHM) system, based on strain measurements, was implemented to reduce some of the uncertainty regarding the active load paths occurring at the deck level. The objectives of the SHM study were to obtain more information regarding the actual load paths and ascertain possible types of structural redundancy, to determine how to best model this type of structure, and to find ways to track ongoing deterioration using instrumentation. The SHM study involved controlled truck loading scenarios to permit measurement of the load paths and provide data to compare the measured results to a finite element (FE) model of the instrumented span. In addition, random loading scenarios were used to capture the vertical dynamic response of the structure in order to further refine the FE model. This study focused on the response of one-half of one interior span. A total of 72 strain gauges were installed. The downstream truss was highly instrumented at ten locations, three members of the upstream truss were instrumented to measure the distribution, and the floor joists in the downstream lane were instrumented to establish possible redundancy paths. Using an FE model in combination with the measured strain data, it was found that redundant load paths only existed at the level of the deck. The bottom chord members experienced non-zero strains once the control vehicle was past the span, possibly indicating some level of redundancy. The members believed to relieve a portion of the bottom chord tensile forces included the car joists, edge joists, and the timber deck. The amount of force transferred from the bottom chord to the deck members was found by FE analysis to be highly related to the lateral stiffness of the floor beams. The FE model was adjusted to match the measured results by modifying various modelling parameters. The most important features of the model were that all deck elements were modelled to be located at the elevation of the bottom chord, that the lateral stiffness of the floor beams was reduced by 50% to best represent the transfer of forces to deck elements, and that the stiffness of bottom chord members was reduced to 80% of their pristine values. In combination with calibrated modification factors applied to the measured values, this FE model is believed to be a useful tool to represent the behaviour of the structure to assist in detecting further damage by modelling the strain differential between members, and components of members.

As Aboriginal peoples relocated to urban areas in the 1950s and 1960s they often found that the services they were offered did not suit their needs, to address this issue Aboriginal peoples began advocating for organizations of their own. Two such organizations include the Saskatoon Indian and Métis Friendship Centre and the Community Liaison Committee. This thesis will explore how Aboriginal peoples worked to create organizations that served their needs, rather than assimilating as was expected; how the status blind approach within organizations was resisted; and how these organizations had a strong desire and vision to become self-governing, often demonstrated by engaging in coproduction, even in the very early stages of organizational development. The data collected included archival documents and informant interviews and was analyzed using an adapted form of grounded theory. The research and analysis revealed waves of engagement in coproduction as a way to defy expectations that Aboriginal peoples would assimilate once moving to the city, and rather embrace Aboriginal cultures and practices in the city.

This study explores the factors that influence how three First Nations educators in the City of Saskatoon define ethics, identify ethical dilemmas, and resolve ethical dilemmas.<p> Using the case-study methodology guided by respectful inquiry with First Nations people, the study sought to identify influential factors affecting the ethical considerations among three Aboriginal educators. The research questions were: 1) How do three Aboriginal educators define ethics? 2) How do the three Aboriginal educators identify an ethical dilemma? 3) What factors do the three Aboriginal educators identify as influencing the resolution of ethical dilemmas? The study sought to identify how the educators perceive ethics, and was not meant to be built on a priori theory of ethics. The reliance on ethical theory beyond what was generated by the participants or through relevant and related studies was carefully selected so as not to impede the expression of the understandings of the participants and the interpretations and understandings of the researcher and readers.<p> The study found that the participants identified their definitions, instances, and resolution of ethical dilemmas as reflecting the experiences of the participants. Their histories are a part of the diversity of First Nations people, and it is their stories that illustrate the ethical frameworks of the participants. The study participants reported a connection to their First Nations cultures from which they drew. Their influential experiences, though, have diminished a concrete connection to their First Nations cultures. They maintain a sense of belonging to an Aboriginal collective, and it is this membership that frequently defines their ethical dilemmas.

In 1881, an Ontario-based group known as the Temperance Colonization Society began looking towards the Canadian West with a speculative eye. Interested in acquiring tracts of land from the Canadian Government, the Temperance Colonization Society hoped to one day establish a new colony free from the temptations of alcohol and the troubles associated with older colonies. By 1884, a settlement was established along the south shore of the South Saskatchewan River. This was the beginning of Saskatoon.<p> As Saskatoon grew from a small settlement founded on temperance ideals to a recognized municipal corporation, the meaning of the material culture associated with this transition also changed. Two archaeological sites pertaining to this transition, the Marr Residence at 326 11th Street East (FaNp-5) and the 11th Street Privy site (FaNp-31), currently comprise the only excavated privy assemblages in the city and hold rich potential for shedding light on urban consumption behaviour at the turn of the 20th century. This study will analyze the archaeological assemblages recovered from these excavations under the scope of consumer behaviour. By orienting the essence of this study towards an archaeology of consumerism, information regarding the dimensions of everyday life in the Saskatoon area at the turn of the 20th Century can be ascertained.

A lack of reliable knowledge regarding the problems facing Indian and Metis people has hindered the development of intelligent programs and policies to facilitate their healthy integration into the larger Canadian society. Two large scale studies (Hawthorn, Belshaw, & Jamieson, 1958; Lagassé, 1959) have attempted to alleviate this problem by collecting extensive data on such aspects of Indian and Metis life as the community and family, resources, employment, education, relations with the law, social welfare needs, liquor and administration.<p> These broad studies dealt only indirectly with Indian and Metis philosophies, personalities and modes of thought, areas in which a comprehensive understanding will have to be achieved to thoroughly comprehend the nature of the problems facing people of Indian ancestry. The Hawthorn study stressed that other research which might follow should include topics such as those which lie within the vast area of psychology.
