"Estudo comparativo da resistência às forças de compressão de uma coroa metalocerâmica fraturada e reparada com resina composta híbrida fotopolimerizável com um dente natural permanente e com uma coroa metalocerâmica íntegra" / Comparative study of the resistance to compression forces of a fractured metal ceramic crown and repaired with composite resin with a non-fractured metal ceramic crowns and a permanent natural toothChaves Filho, Antonio Ruy 28 November 2001 (has links)
As porcelanas odontológicas têm sido dos materiais restauradores estéticos aqueles que mais têm evoluído nos últimos anos. Tradicionalmente, elas são friáveis e incapazes de suportar deformações estruturais quando submetidas a stress. Quando usadas na construção de próteses parciais fixas, uma subestrutura metálica é necessária para impedir que se fraturem sob esforços oclusais. Forças de compressão aplicadas em uma porcelana suportada por metal, de tal forma que não seja possível a sua flexão, poderão ser suportadas em elevadas magnitudes. Entretanto, falhas podem acontecer manifestando-se normalmente por fraturas que exigem a intervenção do clínico no sentido de corrigi-las. Diversos são os métodos propostos para o reparo destas fraturas e as pesquisas desenvolvidas no sentido de se avaliar a união dos materiais restauradores às porcelanas. Neste trabalho, foi feita uma análise das possíveis causas de fratura das cerâmicas, os métodos de reparo indicados, materiais empregados para tal e a eficiência dos sistemas indicados frente às variáveis que envolvem o procedimento restaurador da porcelana. A proposta foi avaliar a resistência máxima às forças de compressão de reparos de fraturas de porcelana realizados com uma resina composta híbrida fotopolimerizável, empregando cargas estáticas comparando-a com a resistência de coroas metalocerâmicas íntegras e dentes naturais permanentes, usados como grupo controle. Os resultados mostraram que frente às forças de compressão aplicadas, a coroa metalocerâmica íntegra e o dente natural não apresentaram diferença estatisticamente significante. A coroa metalocerâmica reparada apresentou menor resistência que a coroa / The odontologic porcelains have been out of the esthetic restorative materials those, which have developed the most in the last years. Traditionally, they are brittle and unable to bear structural deformations when submitted to stress. When used in the building of partial fixed prothesis, one metallic framework is needed to avoid them to fracture under occlusal efforts. Forces of compression enforced on a metal supported porcelain in a way, which is not possible to bend, they could be beared in high magnitudes. However, failures can happen normally revealing themselves through fractures, which demand the intervention of the clinician in order to evaluate the association of the restorative materials to porcelains. In this study na analysis has been made of the possible causes of fractures of the ceramics, the indicated repairing methods, the materials used for it and, the efficiency of the variables, which involves the restorative procedure of the porcelain. The aim was evaluate the utmost resistance to the forces of compression in repairs of fractures of porcelain made with a light-cured hybrid composite resin, using static loads and comparing it with the resistance of the nonfractured metal ceramic crowns and permanent natural human teeth, used as control group The results have shown that in the presence of the compression forces loaded to non-fractured metaloceramic crown and the natural tooth have not exhibited statistically meaningful difference. The repaired metaloceramic crown has exhibited less resistance than the non-fractured metaloceramic one. However, there has not been statistically meaningful difference to the permanent natural tooth

Co-operative and state ownership in northern Saskatchewan under the CCF governmentRadloff, Karla 20 October 2008 (has links)
Co-operative and State Ownership in Northern Saskatchewan Under the CCF Government examines the use of social ownership as a policy instrument by the Cooperative Commonwealth Federation (CCF) government in Northern Saskatchewan from 1944 to 1964. Led by Tommy Douglas, the new government defined numerous policy problems in the North stemming from both an economy dominated by private ownership and unstable natural resource based industries. Using two types of social ownership, crown corporations and co-operatives, the CCF sought to rectify these problems and improve the standard of living in Northern Saskatchewan. This study intends to determine whether the CCF government achieved its policy goals in Northern Saskatchewan and concludes that it accomplished its policy specific goals. Although the CCF may not have revolutionized the Northern economy, it did realize some of its policy goals in the North.
<p>
This study is significant because it is the first to focus solely on the program of social ownership that the CCF government implemented in the North and assess the success of the program on the CCFs terms. Moreover, this thesis offers a comprehensive review of the political origins and development of co-operatives in Northern Saskatchewan.

Prosecutor Selected Youth Diversion: Identifying the Circumstances and Conceptualizing the CasesCoady, Kyle N. P. 29 August 2012 (has links)
Crown selected youth diversion has received little academic attention in Canada. As a process that channels offenders out of the formal legal system, diversion purports to achieve contradictory self-serving system and offender-based goals. Using 50 randomly selected prosecution files – half of which the Crown diverted and half of which the Crown prosecuted – a mixed method investigation of diversion assesses cases through quantitative content analysis and grounded theory method. Based on the quantitative analysis, it is argued that there is an emerging patterned nature of Crown selected diversion that is not completely benign. This patterned nature of diversion unearths a distinctive discourse of diversion/non-diversion. Qualitatively, it is argued that the cases are organized around three temporal moments that create an area for distinctions to be made in terms of threat, responsibility, (in)tolerableness and recourse. Seemingly, there is a persistent paradoxical existence of the diversion process that emerges from the case files.
