Petrography, geochemistry and structure of the Timmins area, Ontario

Regional structural analysis of the Timmins area indicates four major periods of tectonic deformation. The DI deformation is characterized by a series of isoclinal FI folds which are outlined in the study area by bedding, pillow tops and variolitic flows. The D2 deformation developed the Porcupine Syncline and refolded the Fl folds about a NE. axis. A pervasive S2 foliation developed during low grade (greenschist) regional metamorphism associated with the D2 deformation. The S2 foliation developed south of the Destor-Porcupine Break. The third phase of tectonic D3 deformation is recognized by the development of a S3 sub-horizontal crenulation cleavage which developed on the plane of the S2 foliation. No meso scopic folds are associated with this deformation. The 8 3 crenulation cleavage is observed south of the Destor-Porcupine Break. The D4 tectonic deformation is recorded as a subvertical S4 crenulation cleavage which developed on the plane of the S2 foliation and also offsets the S3 crenulation cleavage. Macroscopic F4 folds have refolded the F2 axial plane. No metamorphic recrystallization is associated with this deformation. The S4 crenulation cleavage is observed south of the Destor-Porcupine Break. Petrographic evidence indicates that the Timmins area has been subjected to pervasive regional low grade (greenschist) metamorphism which has recrystallized the original mineralogy. South of the study are~ the Donut Lake ultramafic lavas have been subjected to contact medium grade (amphibolite facies) metamorphism associated with the intrusion of the Peterlong Lake Complex. The Archean volcanic rocks of the Timmins area have been subdivided into komatiitic, tholeiitic and calcalkaline suites based on Zr, Ti0 2 and Ni. The three elements were used because of their r e lative immobility during subsequent metamorphic events. Geochemical observations in the Timmins area indicates that the composition of the Goose Lake and Donut Lake Formations are a series of peridotitic, pyroxenitic and basaltic komatiites. The Lower Schumacher Formation is a sequence of basaltic komatiites while the upper part of the Lower Schumacher Formation is an intercalated sequence of basaltic komatiites and low Ti0 2 tholeiites. The variolitic flows are felsic tholeiites in composition and geochemical evidenc e sugg ests that they developed as a n immiscible splitting of a tholeiitic magma. The Upper Schumacher Formation is a sequence of tholeiitic rocks dis p laying a mild iron enrichment. The Krist and Boomerang Formations are the felsic calc-alkaline rocks of the study area which are characteristically pyroclastic. The Redstone Fo rmation is dominantly a calc-alkali ne sequence of volcani c rocks whose minor mafic end me mbers exposed in 1t.he study hav e basaltic komatiitic compositions. Geochemical evidence sugges ts that the Keewatin-type se dimentary rocks have a composition similar to a quartz diorite or a granodiorite. Fi e l d obs ervations and petrographic evidence suggests that they were derived fr om a distal source and now repr esent i n part a turbidite sequence. The Timiskaming-type sedimentary rocks approach the c omp osi t ion of the felsic calc-alkaline rocks of the study area . The basal conglomerate in the study are a sugge s ts that th e uni t was derived fr om a proximal source. Petrographic and ge ochemical evidence suggests that the peridotitic and pyroxenitic komatiites originated as a 35-55% partial melt within the mantle, in excess of 100 Km. depth. The melt ros e as a diapir with the subsequent effusion of the ultramafic lavas, The basaltic komatiites and tholeiitic rocks originated in the mantle from lesser degrees of partial melting and fractionated in low pressure chambers. Geochemical evidence suggests a "genetic link" between the basaltic komatiites and tholeiites, The calc-alkaline rocks developed as a result of the increa.se In PO in the magma chamber. The felsic calcalkaline rocks are a late stage effusion possibly the last major volcanic eruptions in the area.

The effect of age on the structure and compostition of the cell walls of Choanephora cucurbitarum

The effect of age on the structure and composition of isolated and purified cell walls from cultures of Choanephora cucurbitarum was investigated by microchemical analyses, visible and infrared spectrophotometry, x-ray diffractometry and electron microscopy. Qualitative evaluation revealed the presence of lipids, proteins, neutral sugars, strong alkali soluble sugars, chitin, chitosan and uronic acids in the cell walls of both the 1 and 7 day old cultures. As the mycelium aged, there was a slight but statistically significant increase in the protein content, and a pronounced rise in the chitin and neutral sugar constituents of the cell walls. Conversely, the decrease in the chitosan content during this period had the net effect of altering the chitin: chitosan ratio from near unity in the younger cultures, to a 2:1 ratio in the 7 day old cell wall samples. Glutaraldehyde-osmium fixed thin sections of the 1 day old vegetative hyphae of £. curbitarum revealed the presence of a monolayered cell wall, which upon aging became bilayered. Replicas of acid hydrolysed cell walls demonstrated that both the 1 and 7 day old samples possessed an outer layer which was composed of finely granular amorphous material and randomly distributed microfibrils. The deposition of an inner secondary layer composed of parallel oriented microfibrils in the older hypha was correlated with an increase in the chitin content in the cell wall. The significance of these results with respect to the intimate relationship between composition and structure is discussed.

The Falkland Islands War of 1982: a legal, diplomatic and strategic evaluation

The Falkland Islands War of 1982 was fought over competing claims to sovereignty over a group of islands off the east coast of South America. The dispute was between Argentina and the United Kingdom. Argentina claims the islands under rights to Spanish succession, the fact that they lie off the Argentine coast line and that in 1833 Great Britain took the islands illegally and by force. The United Kingdom claims the islands primarily through prescription--the fact that they have governed the islands in a peaceful, continuous and public manner since 1833. The British also hold that the population living on the islands, roughly eighteen hundred British descendants, should be able to decide their own future. The United Kingdom also lays claim to the islands through rights of discovery and settlement, although this claim has always been challenged by Spain who until 1811 governed the islands. Both claims have legal support, and the final decision if there will ever be one is difficult to predict. Sadly today the ultimate test of sovereignty does not come through international law but remains in the idea that "He is sovereign who can defend his sovereignty." The years preceding the Argentine invasion of 1982 witnessed many diplomatic exchanges between The United Kingdom and Argentina over the future of the islands. During this time the British sent signals to Argentina that ii implied a decline in British resolve to hold the islands and demonstrated that military action did more to further the talks along than did actual negotiations. The Argentine military junta read these signals and decided that they could take the islands in a quick military invasion and that the United Kingdom would consider the act as a fait accompli and would not protest the invasion. The British in response to this claimed that they never signaled to Argentina that a military solution was acceptable to them and launched a Royal Navy task force to liberate the islands. Both governments responded to an international crisis with means that were designed both to resolve the international crisis and increase the domestic popularity of the government. British Prime Minister Margaret Thatcher was facing an all-time low in popularity for post-War Prime Ministers while Argentine President General Galtieri needed to gain mass popular support so he could remain a viable President after he was scheduled to lose command of the army and a seat on the military junta that ran the country. The military war for the Falklands is indicative of the nature of modern warfare between Third World countries. It shows that the gap in military capabilities between Third and First World countries is narrowing significantly. Modern warfare between a First and Third World country is no longer a 'walk over' for the First World country.

Subjective, behavioural and electrophysiological measurements of the time-course and intensity of sleep inertia after a full night of sleep /

Several recent studies have described the period of impaired alertness and performance known as sleep inertia that occurs upon awakening from a full night of sleep. They report that sleep inertia dissipates in a saturating exponential manner, the exact time course being task dependent, but generally persisting for one to two hours. A number of factors, including sleep architecture, sleep depth and circadian variables are also thought to affect the duration and intensity. The present study sought to replicate their findings for subjective alertness and reaction time and also to examine electrophysiological changes through the use of event-related potentials (ERPs). Secondly, several sleep parameters were examined for potential effects on the initial intensity of sleep inertia. Ten participants spent two consecutive nights and subsequent mornings in the sleep lab. Sleep architecture was recorded for a fiiU nocturnal episode of sleep based on participants' habitual sleep patterns. Subjective alertness and performance was measured for a 90-minute period after awakening. Alertness was measured every five minutes using the Stanford Sleepiness Scale (SSS) and a visual analogue scale (VAS) of sleepiness. An auditory tone also served as the target stimulus for an oddball task designed to examine the NlOO and P300 components ofthe ERP waveform. The five-minute oddball task was presented at 15-minute intervals over the initial 90-minutes after awakening to obtain six measures of average RT and amplitude and latency for NlOO and P300. Standard polysomnographic recording were used to obtain digital EEG and describe the night of sleep. Power spectral analyses (FFT) were used to calculate slow wave activity (SWA) as a measure of sleep depth for the whole night, 90-minutes before awakening and five minutes before awakening.

Comics carnet : the graphic novelist as global nomad

An interdisciplinary approach is used to identify a new graphic novel genre, 'comics camet', and its key features. The study situates comics camet in a historical context and shows it to be the result of a cross-pollination between the American and French comics traditions. Comics camet incorporates features from other literary genres: journalism, autobiography, ethnography and travel writing. Its creators, primarily European rriales, document their experiences visiting countries that Europe has traditionally defined as belonging to the 'East'. A visual and narrative analysis, using theoretical perspectives derived from cultural and postcolonial studies, examines how comics camet represents the non-European other and identifies the genre's ideological assumptions. Four representative texts are examined: Joe Sacco's Palestine (2001), Craig Thompson's, Camet de Voyage (2004), Guy Delisle's Pyongyang (2005) and Mrujane Satrpi's Persespolis 2 (2004). The study concludes that the comics camet genre simultaneously reinforces and challenges stereotypical assumptions about non-European people and places.

Bargaining Power Dynamics and the Negotiation of Commercial Rights and Obligations: A Case of Athlete Agreements

This qualitative case study explored how the structural power imbalance in high performance sport influenced the bargaining process and resulting commercial rights and obligations of a single Canadian national sport organization’s (NSO1) Athlete Agreement. Principles comprising the doctrine of unconscionability, specifically the identification of a power imbalance between contracting parties, and the exploration of how that power imbalance influenced the terms of the contract, provided a framework to analyze factors influencing the commercial contents of NSO1’s Athlete Agreement. The results of this analysis revealed that despite the overarching influence of the inherent structural power imbalance on all aspects of NSO1 and its membership, an athletes’ level of commercial appeal can reach such heights as to balance the bargaining positions of both parties and subsequently influence the commercial contents of the Athlete Agreement.

The electromyographic threshold in boys and men

Abstract Background Children have been shown to have higher lactate (LaTh) and ventilatory (VeTh) thresholds than adults, which might be explained by lower levels of type-II motor-unit (MU) recruitment. However, the electromyographic threshold (EMGTh), regarded as indicating the onset of accelerated type-II MU recruitment, has been investigated only in adults. Purpose To compare the relative exercise intensity at which the EMGTh occurs in boys versus men. Methods Participants were 21 men (23.4 ± 4.1 years) and 23 boys (11.1 ± 1.1 years), with similar habitual physical activity and peak oxygen consumption (VO2pk) (49.7 ± 5.5 vs. 50.1 ± 7.4 ml kg−1 min−1, respectively). Ramped cycle ergometry was conducted to volitional exhaustion with surface EMG recorded from the right and left vastus lateralis muscles throughout the test (~10 min). The composite right–left EMG root mean square (EMGRMS) was then calculated per pedal revolution. The EMGTh was then determined as the exercise intensity at the point of least residual sum of squares for any two regression line divisions of the EMGRMS plot. Results EMGTh was detected in 20/21 of the men (95.2 %) and only in 18/23 of the boys (78.3 %). The boys’ EMGTh was significantly higher than the men’s (86.4 ± 9.6 vs. 79.7 ± 10.0 % of peak power output at exhaustion; p < 0.05). The pattern was similar when EMGTh was expressed as percentage of VO2pk. Conclusions The boys’ higher EMGTh suggests delayed and hence lesser utilization of type-II MUs in progressive exercise, compared with men. The boys–men EMGTh differences were of similar magnitude as those shown for LaTh and VeTh, further suggesting a common underlying factor.

Contribution de l’éthique théologique du caractère à l’accompagnement pastoral des jeunes adultes

Ce projet doctoral cherche à élaborer une approche éthique d’accompagnement des jeunes adultes (20-35 ans) en milieu pastoral. Prenant son point de départ dans la méthode praxéologique, il déploie une observation de la pratique d’un certain type d’accompagnement pastoral, puis réfléchit sur des traits de la jeunesse actuelle, surtout québécoise. Bien que cherchant à affirmer leur autonomie, les jeunes qui consultent ponctuellement un prêtre cherchent souvent des réponses à leurs dilemmes moraux. La thèse s’inspire des théoéthiciens nord-américains, Stanley Hauerwas et Craig Dykstra pour dépasser la préoccupation du « quoi faire ». En effet, ces auteurs principaux de la thèse se centrent sur la personne, la réalisation de son soi et le type d’homme ou de femme qu’elle veut être. L’accent est donc mis sur l’être, la totalité de la personne, et non seulement sur le faire. Une surenchère de l’importance du « faire » et de l’« action » renvoie à la fois à notre société post-technologique, centrée sur la productivité de la personne et à une morale catholique prescriptive. Néanmoins, l’éthique du caractère propose un chemin de conversion de la question de savoir « quoi faire » dans celle de savoir « comment vivre ». Sur le plan théologique, elle recentre et réinterprète des aspects essentiels du christianisme, soit les récits, la tradition comme histoire, communauté et imagination. Cette approche revitalise le paysage éthique et le style d’accompagnement pastoral auprès des jeunes adultes. En tant que prêtre catholique souvent consulté par des gens de cette catégorie d’âge (20-35 ans), notre projet de thèse se veut inspirateur d’une nouvelle pratique d’accompagnement éthico-pastoral.

L’architecture engagée du «Case Study House Program» de la revue Arts and Architecture de 1945 – 1966 : une confluence génératrice

La conception architecturale du logis, individuel ou collectif, est un défi majeur pour les architectes depuis l'avènement de la modernité. Au début du 21ième siècle, la multiplicité des conditions démographiques et celle de la mobilité des personnes sous-tendent la complexité de l'élaboration de prototypes ou de modèles d'habitation. Que peut-on apprendre des expériences menées dans ce domaine après la seconde guerre mondiale aux États-Unis ? Ce mémoire de maîtrise est consacré à l'étude d’un cas particulier celui du programme de création architecturale réalisée en Californie de 1945 à 1966, connu sous le nom de : «Case Study House Program». Ce programme, dirigé par John Entenza, éditeur de la revue Arts and Architecture, rassemblait de nombreux architectes dont les plus célèbres sont Charles et Ray Eames, Richard Neutra, Craig Ellwood et Pierre Koenig, tous auteurs de maisons modernes devenues oeuvres canoniques dans l’histoire de l’architecture. L'analyse détaillé de ce cas et de ses retombées devrait permettre de mieux cerner les aspects suivants: la portée critique du CSHP (case study house program) qui s'opposait aux modèles dominants du marché immobilier, modèles généralement inspirés de styles traditionnels; le potentiel et les limites d'une telle démarche face à la demande sociale; la dimension anticipatrice des propositions du CSHP pour la conception de logis mieux adaptés aux besoins du 21ième siècle, en particulier ceux qui découlent des changements démographiques et de la mobilité géographiques des personnes; la valeur d'exemple du CSHP pour mieux comprendre les fondements de la résistance du public aux innovations architecturales, autant du point de vue technique que du point de vue esthétique.

Profils d'utilisation d'antipsychotiques en conditions réelles dans la population de personnes âgées démentes vivant à domicile : impact des interventions de communication de risque

Les antipsychotiques (APs) sont fréquemment prescrits pour les troubles comportementaux associés à la démence. Or, ces produits ont fait l'objet de trois mises en garde (2002, 2004, 2005) en raison d'une augmentation du risque d'événement cérébrovasculaire et de décès. L’objectif de ce mémoire est d’évaluer l'utilisation d’APs dans la population de personnes âgées démentes vivant à domicile, et de déterminer l’effet des mises en garde sur les profils observés. Une cohorte rétrospective de 10,969 personnes âgées démentes ayant débuté un traitement par AP entre le 1er janvier 2000 et le 31 décembre 2009 fut identifiée à partir des banques de données de la Régie de l'assurance maladie du Québec (RAMQ). Des séries chronologiques segmentées ont permis de quantifier l’effet des mises en garde sur l'utilisation d’APs. L'effet de la mise en garde de 2005 sur les caractéristiques des patients traités ainsi que sur les profils d'utilisation (dose et durée) a été évalué, respectivement par des modèles de régression logistique et de régression linéaire multivariés. Le taux délivrance d'APs atypiques a augmenté au cours du temps jusqu'à la mise en garde de 2005 pour ensuite diminuer de 8.96% (IC 95% : -11.91% – -6.02%). L'analyse par produit a révélé la même tendance pour la rispéridone, le seul AP approuvé au Canada pour les personnes âgées démentes. En revanche, le taux de délivrance de quétiapine, qui est hors-indication, a continué d'augmenter. Le taux d'initiation de traitement par APs a cependant diminué au cours du temps pour tous les produits. Les mises en garde ne semblent pas être associées avec un changement dans les caractéristiques des patients traités, ni avec les doses et durées d’utilisation. Le manque d'efficacité des mises en garde est probablement en partie lié à l'absence d'alternatives thérapeutiques pour le traitement des troubles psychologiques et comportementaux chez les patients atteints de démence.
