The primary goal of this study was to investigate and compare the fermentation performance of malt produced from eleven Canadian two-row barley varieties grown during the 2007 and 2008 crop seasons. Common malting varieties tested included Harrington, AC Metcalfe, CDC Copeland, CDC Kendall, and feed varieties CDC Dolly, CDC Bold, CDC Helgason and McLeod. As well, three experimental varieties, TR251; TR306; and BM9752D-17, were included in this study due to their varied display of enzymatic activity; of chief interest was the ?-amylase thermal stability. Fermentations were carried out using the standard miniaturized fermentation assay and SMA yeast. Apparent Extract (AE), absorbance, fermentable carbohydrates, and ethanol were measured throughout fermentation. Attenuation, carbohydrate and ethanol data were modeled using the logistic equation, and absorbance data was modeled using the newly developed Tilted Gaussian equation. Results indicate that all but the feed varieties fermented well, achieving low final attenuation, and exhibiting similar fermentation characteristics. Despite only minor performance differences among the top fermenters, it was found that between crop seasons both AC Metcalfe and CDC Copeland fermented as well or better than Harrington, as measured by their respective Apparent Degree of Fermentation (ADF). Harrington displayed substantial performance variation between seasons, while test variety BM9752D-17 fermented the most consistently between years, displaying enhanced fermentation to that of Harrington in 2008. Despite high ?-amylase thermostability, BM9752D-17 did not display enhanced fermentation performance to that of CDC Copeland or AC Metcalfe.

The purpose of this thesis is to explore the concepts of privacy and to propose design patterns for providing privacy for individuals and families in the context of Montreal row houses. / The study examines and explores the notion of privacy through a multidisciplinary literature review and links this notion to the row houses. The morphogenesis of row houses, the role of occupants and the built environment in the evolution of privacy issues in this housing type is investigated through a broad historical review and site surveys. The research leads to a series of proposed design patterns which can be used as tools for provision and maintenance of privacy in row houses. Specific consideration is given to present and future housing requirements.

Death row is a space across the United States that continues to expand, not only in numbers, but in the length of time inmates spend confined there. Fewer and fewer inmates are executed and death row is now increasingly the only punishment of capital convicts. This thesis examines the retributive and punitive treatment of death-sentenced offenders within that space and, by viewing that form of imprisonment as part of a communication process, it assesses the contribution it makes to the death penalty more generally in the USA to argue that death row imprisonment is crucial in sustaining the distinction of capital offenders, and the death penalty itself.Just as death row receives images from wider culture, it simultaneously generates images that complement and validate those it receives, of death sentenced offenders as dangerous monsters. These images, of offenders who require punitive detention, align with the dominant supportive rationale of capital punishment, retribution, and provide a basis for continued death penalty support in an era of declining executions.In the “hidden world” of death row, prisoners are left to be abused, mistreated, and denied privileges and opportunities available to other prisoners. The capital offender is presented by his death row incarceration as different from all other offenders serving other sentences, even life without parole. Death row incarceration communicates the worth and status of the condemned, presenting him as a dangerous, and dehumanised other, who needs to be securely detained, and restricted. Thus death row validates and justifies the cultural needs of capital punishment. Just as wider culture, including, specifically, the legal community, dictates a requirement for punitive detention, death row corroborates that image with its own in a self-affirming loop. Death row is therefore functional beyond the mere holding of offenders, it affirms cultural descriptions of the condemned and thus justifies, and provides support for, the very continuation of capital punishment itself.

This thesis is a treatise on optimal assembly methods for double row ball bearings. As with common single row bearings, double row ball bearings, consist of four general components, namely, an inner ring, an outer ring, a complement of balls and a cage or retainer to keep the balls separate. Unlike single row bearings, however, double row ball bearings have two complements of balls in two distinct parallel races. Although this double row configuration is desirable in a number of applications, it makes the bearings more difficult and expensive to assemble. In addition, current manual assembly procedures require a great deal of digital manipulation, leading to concern about carpal tunnel syndrome and other long-term repetitive motion injuries. This thesis attempts to develop an improved assembly process for all types of double row bearings. Although the work is intended to be general, the Torrington 5203 double row ball bearing is adopted as a specific application example. This bearing's assembly difficulties and additional cost are a result of its manual Conrad assembly method and a rubber O-ring and groove used solely for bearing assembly. In the assembly process, the O-ring supports the upper balls temporarily until the two rings can be aligned concentrically, thus snapping the balls into the bearing races. This thesis addresses the replacement of the rubber O-ring and explores opportunities for bearing assembly automation. Design synthesis of a retractable or reusable assembly component to replace the rubber O-ring supporting the upper balls during assembly is presented. A large group of design concepts are developed and evaluated, resulting in a small group of feasible designs. These feasible solutions are then tested, and a design that has the potential immediate implementation in an improved manual assembly process is proposed. In addition, two design concepts are presented as candidates for possible implementation in an automated assembly process. / Master of Science

The United States is one of few Western nations that administers capital punishment to their condemned criminals. Texas has executed the most inmates of any state in the U.S. This prompted questions about the psychological characteristics of death row inmates. The purpose of this essay is to widen the perspective on inmates serving capital sentences by analyzing their final statements. The focus of this essay was centered on acute anxiety of death among inmates, visible in their final statements, as a result of an accelerated process of dying. Using three of the eight phases in Erik H. Erikson’s psychosocial theory on individual development, where the final phase is centered around the conflict between integrity and despair, the inmates’ final statements were analyzed. Despair is here identified by three factors: an inability to accept ones situation, anxiety of death and a strong feeling of regret. Through textual analysis, certain codes affiliated with Erikson’s theory were identified and studied. In addition to this, the inmates’ trust and comfort in a transcendental power was also studied as a part of mitigating anxiety among inmates. Erikson’s theory is in this essay supplemented by discourse analysis and discourse psychology in particular to provide additional context to the inmates’ situation. A sociopolitical dimension was also added to provide further analysis. The study found that inmates tend to regret the actions that led them to the incarceration, while also accepting their situation, which does not indicate acute anxiety of dying but rather expression of what is in this paper called the inmate discourse, in which inmates are expected by the wider society to regret their actions. Inmates also tend to describe God or a transcendental authority as a forgiving and loving one, which in this paper is identified not only as a way of finding comfort in a dire situation, but also to belong to a larger American community through religious identification.

Accurately delivering and precisely timing sprinkler irrigation improves peanut yield and profitability, but there are no data on how to achieve this in the mid-southern USA where furrow-irrigation dominates. This research was conducted to determine if soil water potential could be manipulated through land preparation method, irrigation delivery, and irrigation scheduling. The effects of land preparation method (flat vs bed), furrow-irrigation delivery (every vs every-other furrow), and irrigation scheduling [Food and Agriculture Organization and drainage paper 56 (FAO-56), - 50 kPa, -75 kPa, and -100 kPa] on peanut yield, net returns above irrigation costs, and irrigation water use efficiency were investigated near Stoneville, MS on a Bosket very fine sandy loam. Our data indicate that regardless of land preparation method, peanut yield, net returns above irrigation costs, and irrigation water use efficiency are most often optimized in the mid-southern USA by irrigating every other furrow at a threshold of -50 kPa.
