Gardiner Dam is located on the South Saskatchewan River approximately 100 km south of Saskatoon, SK. After the start of construction, the River Embankment experienced downstream movement in the shale portion of the foundation. Observed movements are occurring on a well-defined shear plane within the shale layer. This continuing foundation deformation raises concerns regarding the long-term stability of the structure and the effect of continuing deformation on the integrity of the embankment and ancillary works. The mechanism(s) responsible for the ongoing movements are not fully understood. As such, prediction of on-going deformation has had only a limited success. In the work presented in this dissertation, historic geotechnical instrumentation data was used to identify a potential mechanism of movement within the shale foundation. The potential mechanism thus identified can be briefly described as a combination of elastic deformation and consolidation within the shale. As the reservoir level rises, part of the increase in horizontal thrust is transferred to the shale. Since the shale is relatively stiff and has a low hydraulic conductivity, the increase in loading is; therefore, transferred to the porewater, resulting in generation of excess porewater pressures in shale. When the reservoir is high a portion of the excess porewater pressure dissipates. The observed horizontal movement along the shear zone is then developed from elastic deformation and horizontal consolidation of the shale from dissipation of excess porewater pressure. An analytical model was developed from the proposed conceptual model and had general success predicting the horizontal displacement based on the reservoir level and time period. However, the model was sensitive to the reservoir level and several variables within the shale including the hydraulic conductivity and porewater parameter B. Overall, the material variables such as hydraulic conductivity and B can be refined; however, without having an accurate reservoir prediction into the future, the ability for this model to predict the displacement in the foundation will be limited.

Samuel Rawson Gardiner (1829-1902) has traditionally been viewed as a quintessential late Victorian historian. His subject was politics, his methods consisted of empirical research in the archives, he wrote the kind of dry narratives being propounded in the newly professionalised discipline, and his account of the past was coloured by his religious and political biases. Such characterisations are, however, very wide of the mark. They have been constructed from the study of the context of his life. Through a close reading of the full range of his texts, it is possible to deconstruct this dominant image and put in its place a very different account of his thought, his methods and his writing. Gardiner was influenced by German Idealist philosophy, and as a result his interests lay in intellectual currents, his methods of analysis rested on the Fichtean dialectical method coupled with a dedication to insights derived from empathy and the imagination, and he understood the power of literary representation.

Dans ce travail nous nous intéressons à la géométrie de l’espace de Teichmüller via la longueur extrémale et à sa relation avec d’autres géométries. En effet, via le théorème d’uniformisation de Poincaré, l’espace de Teichmüller d’une surface orientable de type finie est un espace qui “classifie” aussi bien les structures hyperboliques de cette surface que les structures conformes. Suivant la classification utilisée, on obtient deux compactifications différentes de cet espace, qui sont respectivement la compactification de Thurston et la compactification de Gardiner-Masur. La première étant induite par la longueur hyperbolique et la deuxième par la longueur extrémale. Dans une première partie, on considère les compactifications dites “réduites” de Thurston et Gardiner-Masur. On montre qu’il existe une bijection naturelle entre les deux et que le groupe des auto-homéomorphismes du bord réduit de Thurston est canoniquement isomorphe au groupe modulaire étendu de la surface sous-jacente. Dans une deuxième partie, on étudie la convergence de certaines déformations de structures conformes aussi bien sur le bord de Thurston que sur celui de Gardiner-Masur. Ces déformations, appelées déformations horocycliques, sont un analogue des tremblements de terre de structures hyperboliques. Enfin, dans une troisième et dernière partie, on introduit une compactification à la Gardiner-Masur de l’espace de Teichmüller d’une surface à bord. On généralise des résultats obtenus dans le cas sans bord, et on établit quelques différences. / In this thesis we are interested in the extremal length geometry of Teichmüller space and the links with other geometries. In particular, we work on two different compactifications of Teichmüller space, namely, the Thurston compactification and the Gardiner-Masur compactification. In the first part, we consider the so-called reduced compactifications of Thurston and Gardiner-Masur. We show that there exists a canonical bijection between them and that the group of self-homeomorphisms of the reduced Thurston boundary is canonicaly isomorphic (except for a few cases) to the extended mapping class group of the corresponding surface. In the second part, we study the asymptotic behaviour of some conformal structure deformations to the Thuston boundary and to the Gardiner-Masur boundary. These deformations are called horocyclic deformations and they are analogous to earthquakes of hyperbolic structures. Finally, in the last part, using extremal length we extend the notion of Gardiner-Masur compactification to surfaces with non-empty boundary, and we investigate differences with the case without boundary.

This thesis examines the production of Tamil youth in the state of Canada as threats, extremists, radicals, terrorists, and as subjects to be engaged in de-politicized humanitarian discourses of reconciliation and peace. By drawing attention to the exclusion of Tamils from rights in legal proceedings, the positioning of youth protesters as harbingers of a multicultural 'crisis,' and the role of education in securing Canada's response to the MV Sun Sea as a 'humanitarian' project, I argue that the targeting Tamils is not only integral to Sri Lanka's ongoing genocide, but is also crucial to the Canadian state's project of white settler colonialism. In examining the law, media and education as sites of racial management in the 'War on Terror' and its globalized counter-terrorism regime I identify the targeting of Tamil diaspora youth as a necessary racial logic for the legitimacy of the Canadian state in an era of official multiculturalism.

Personal på Högskolan i Gävle tycks periodvis uppleva dålig komfort ikontorsrummen på södersidan i skolans gamla kasernbyggnader. En undersökninggjordes därför på högskolan i april månad i tre kontor, ett med fönsterhuvudsakligen i norrläge och två med fönster huvudsakligen i söderläge. Syftet varatt kartlägga den termiska komforten och luftkvaliteten i de olika väderstrecken ochjämföra med gällande rekommendationer, bland annat genom att beräkna PMV vidolika tillfällen. Vidare undersöktes potentiella samband mellan ute- och inneklimatsamt tunna gardiners inverkan på termostat, värmeflöde och komfort. Den undersökta byggnaden är en äldre stenbyggnad med ovanligt välisoleradefönster och termostatstyrda, vätskeburna radiatorer. Byggnaden har FTX-ventilationmed ett till- och ett överluftsdon i varje kontorsrum. Mätningarna utfördes meddataloggrar som mätte lufttemperatur, relativ luftfuktighet och koldioxidhalt. I tvåav rummen mättes även globtemperatur. Utöver det mättes lufthastighet på tre olikahöjder i två av rummen samt ventilationsflödet i samtliga rum. Resultatet visade att inomhus- och utomhustemperatur har en relativt högkorrelation. Relativa luftfuktigheten var nästan alltid högst i norrläge, men i samtligarum var den låg – lägre än vad som rekommenderas i riktlinjerna. Soligt väderpåverkade temperatur och relativ luftfuktighet inomhus mest av alla vädervariabler,men personnärvaro och ventilation påverkade mer än utomhusklimatet. Kontor isöderläge hade som förväntat högre temperatur än i norrläge, och översteg deriktlinjer som finns för temperatur i kontor. Som följd av detta blev PMV högre isöderläge, tillfälligt högre än komfortgränsen 0,5, med ett högsta värde på 1,41. Kontoret i norrläge höll sig vid de undersökta tillfällena inom intervallet föraccepterat PMV med ett lägsta värde på -0,35. Detta tyder på att värme i söderlägeär ett större problem än kyla i norrläge. Lufthastigheterna blev låga i bådaväderstrecken. Ventilationsflödena visade sig vara 2/3 av det projekterade värdet,men ändå låg koldioxidhalten på en acceptabel nivå enligt riktlinjer. Gardiner påverkade komforten mer i söderläge än norrläge, men påverkade intetillräckligt mycket för att komma ner i en acceptabel komfortnivå vilket kan bero påatt de var av mycket tunt material. Det var svårt att se tydlig gardinpåverkan påtermostaten, men fråndragna gardiner kan leda till att termostaten reagerar påtemperaturökningar i ett rum snabbare. Däremot påverkades värmeflödet tydligaregenom fönstret av gardinerna. Skillnaden i värmeflödet vid för- och fråndragnagardiner blev 4,1 W. / Employees at University of Gävle seem to periodically experience suboptimalcomfort in south facing offices in the school’s old barrack buildings. Therefore, acase study was conducted in April in three offices, one facing north and two facingsouth. The aim of the study was to map the thermal comfort and air quality in thedifferent directions and compare these to the existing recommendations, includingcalculating PMV at different times. A potential correlation between out- and indoorclimate was also examined, as well as the effect of thin curtains on the thermostat, heat flux and comfort. The University of Gävle is an old brick building with unusually well insulatingwindows and thermostatically regulated, waterborne radiators. The building hasmechanical ventilation with heat recovery, and each office has one supply and oneover-air diffuser. The measurements were made with data loggers that measured airtemperature, relative humidity and carbon dioxide. The globe temperature was alsomeasured in two of the rooms. The air velocity on three heights was measured aswell in two of the offices and the ventilation flow was measured in all the rooms. The result showed that indoor- and outdoor temperature have a relatively highcorrelation. The relative humidity was almost always higher in the north facingoffice, but in all the rooms it was low – lower than the recommended guidelines.Sunny weather affected the indoor temperature and relative humidity the most of allthe weather variables, but presence of people and ventilation affected more than theoutdoor climate. South facing offices had as expected a higher temperature thannorth facing ones, and exceeded the guidelines concerning temperatures in offices.Due to that the PMV was higher in the south facing office, temporarily exceedingthe comfort limit of 0,5, with a maximum value of 1,41. The north facing office waswithin the limits during the measurements and had a minimum value of -0,35. Thisindicates that heat in the south facing office is more of a problem than coldness inthe north facing office. The air velocities were low in both directions of thebuilding. The ventilation flow turned out to be 2/3 of the intended value, but thecarbon dioxide content was still acceptable according to guidelines. Curtains influenced the comfort more in the south facing office than in the northfacing office, but they didn’t influence enough to get to an acceptable comfort level,which may be because of the very thin material. It was difficult to see a distinctinfluence from the curtains on the thermostat, but using no curtains could lead tothe thermostat responding faster to increases in temperature in a room. However,the heat flow through the window was influenced more distinctly by the curtains.The difference in heat flow when using curtains compared to no curtains was 4,1 W.
