Complex deformation processes observed in massive slow-moving, active, landslides are contributed to by topography, non-uniform shear surfaces, heterogeneous rockmass and shear zone strength characteristics, composite failure mechanisms and hydrogeology. This thesis provides a systematic means to account for geology, geomorphology and geomechanics when interpreting slope deformation processes. Significant contributions to the field of landslide geomechanics have been made by analyzing how spatially discriminated slope deformations are influenced by spatial variation of geological and geotechnical factors and temporal changes in piezometric levels. The Downie and Beauregard landslides are massive instabilities that have extensive histories of slope monitoring and observational assessment, and where detailed site investigations have been completed. A methodology has been developed for the interpretation of 3-dimensional shear zone geometries using spatial prediction algorithms complemented by sound engineering judgment. The applicability of this process to other spatial data, such as displacement or piezometric records and measurements of material properties is demonstrated. Composite landslide deformations have been analyzed for both Downie and Beauregard to characterize global slope behaviour and identify localized events. Furthermore, a new interpretation of landslide morphological regions at Downie is provided. The research presented in this thesis demonstrates the importance and value of 3-dimensional numerical modelling. A rigorous procedure to numerically simulate large landslides has been developed. This sophisticated method accounts for complex geometries, heterogeneous shear zone strength parameters, internal shears, interaction between discrete landslide zones and piezometric fluctuations. This advance in state-of-the-art landslide modelling provides an important tool for investigating dynamic landslide systems. Based on Downie and Beauregard field data numerical models have been calibrated to reproduce observed slope behaviour. The calibration process has provided insight on key factors controlling massive slope mechanics. Calibrated models are used to investigate how trigger scenarios may accelerate deformations at Downie and the effectiveness of a proposed slope drainage system at Beauregard. The ability to reproduce observed behaviour and forward test hypothesized changes to boundary conditions has valuable application in landslide hazard management. The capacity of decision makers to interpret large amounts of data, respond to rapid changes in a system and understand complex slope dynamics has been enhanced. / Thesis (Ph.D, Geological Sciences & Geological Engineering) -- Queen's University, 2010-09-24 14:13:43.605

A terrain analysis of the Shiloh Battlefield is presented in conjunction with a meteorological assessment of the conditions prevalent during the battle. The intent of the analysis was to ascertain the effect that conditions might have played upon the strategic and tactical actions prior to, and during the Battle of Shiloh, 1862. The significance of this study was to determine the influence of meteorological and geographical factors upon the two armies. Values for temperature and precipitation were estimated using the PDSI and data from NOAA. According to the model it was a very wet year. Weather and geography clearly played a role in how and when the Battle of Shiloh was fought. Due to the high number of casualties, however, the Battle of Shiloh would change how warfare would be conducted in the United States.

Sweetpotato (Ipomoea batatas (L.) Lam.) is a root crop well established throughout the world's tropical and sub-tropical regions. Despite sweepotato's importance, it has been under-researched relative to many other major crops. The main objective of this thesis is to contribute to a fuller understanding of the genetic and physiological factors underlying the production of sweetpotato storage roots for human consumption. The sweetpotato genome is diverse and subject to high levels of natural somatic mutation. Applying the AFLP (amplified fragment length polymorphism) technique allowed a direct comparison of inter and intra-cultivar DNA (deoxyribonucleic acid) base sequence variation. Analysis of the variation indicated that although sweetpotatoes are clonally propagated, clones show a lack of genetic fidelity to their source. Further, the level of genetic variation within the cultivar 'Owairaka Red' indicated the continuing emergence of distinct new strains. Plant field establishment represents the interaction of both propagation and growth phases of storage root production. A range of establishment techniques were investigated in a field trial under commercial conditions. Sprouts cut from seed roots and held for six days rather than immediate planting improved establishment as measured by growth, at little expense. Plug raised plants also improved establishment, while potentially reducing the degree of intra-cultivar genetic variation. Plant carbohydrate partitioning in three cultivars, 'Beauregard', 'Beniazuma' and 'Owairaka Red' was examined by field trial over the period of storage root growth. While cultivars differed in the proportions of dry matter partitioned to leaf, stem and root organs, the cultivar specific ratios of leaf to stem dry weight were relatively stable over time. Total storage root dry weight increased with time for all cultivars, but the distribution of storage root grades by size was cultivar specific. Within the storage roots % dry weight increased over time in all cultivars, but total sugar concentration only increased for 'Beauregard' and 'Beniazuma'. Finally, a storage root disorder called 'brown centre' curtails the temperate growing season so was investigated using low temperature storage and a field trial with various nutrition regimes. The disorder was found to be associated with susceptible germplasm, high soil nitrogen and harvest time.

Cette étude vise à démontrer la participation de Blanche Lamontagne à l'entreprise de reconnaissance des femmes de lettres. L'élaboration de sa trajectoire ascendante particulière (1889-1918), en parallèle avec le tableau du champ littéraire au tournant du siècle et les trajectoires typiques des écrivains masculins et féminins, illustre comment elle se distingue de la génération de femmes journalistes qui la précède et comment elle annonce celle des femmes poètes de l'entre-deux-guerres. En fait, nous estimons qu'elle représente une étape intermédiaire entre ces deux générations à cause de la consécration institutionnelle rapide qu'elle acquiert grâce à ses études supérieures et surtout au réseau de la littérature nationale qu'elle intègre. Comme nous le démontrons, son parcours lui permet de s'insérer dans le champ littéraire plus tôt et plus facilement que les écrivaines avant elle.

The purpose of this thesis was to study the efforts of ten Utah artists who played significant roles in formulating early Utah art history.
