2010 — The application of the local remedies rule under the African Charter on Human and Peoples' Rights: with a case study of communications from the Niger DeltaRésumé
The thesis argues that the local remedies rule as applied by the African Commission in the Niger Delta cases in a flexible manner which focused on the Respondent State's obligation to provide effective legal redress rather than the mechanical act of exhaustion of local remedies by the petitioner, represents a correct application of the rule in human rights protection and that the African Commission's pronouncements regarding the absence of effective domestic legal remedies in Nigeria facilitated improvements in Nigeria's legal institutions. A flexible approach to the local remedies rule should therefore be applicable in all meritorious communications in the African … Lire la suite

1990 — The involvement of second messengers in hippocampal activity and seizure /Résumé
This thesis focusses on the seizure-promoting effects of second messengers, in particular calcium and others activated by calcium in CA1 subfield of rat hippocampus in situ and in vitro. Interictal discharges were simulated in hippocampal slices using the low Ca$ sp{2+}$ model where synaptic transmission is blocked. The antiepileptic drug valproic acid (VPA), which is postulated to potentiate GABAergic responses, reduced the low Ca$ sp{2+}$ field bursts, thereby suggesting a non-synaptic mechanism of action of VPA. Extracellular and intracellular recordings from hippocampal neurones bathed in low Ca$ sp{2+}$ solution revealed that even though evoked transmitter release was blocked, small spontaneous … Lire la suite

1965 — The influence of drugs affecting cardiac adrenergic mechanisms on the movement of radioactive noradrenaline in the perfused heart.Résumé
The primary object of this investigation was to study further the movement of labelled noradrenaline in the isolated perfused rabbit heart, with special reference to its significance in cardiac drug action. Since the movment (uptake and outflow) of noradrenaline might be influenced by changes in heart functions, e.g. coronary flow, heart rate and cardiac contractility, attempts were made to cerrelate movement of noradrenaline with changes in these functions. It is now clearly established that the heart can take up exogenous noradrenaline and that the absorbed noradrenaline appears to be localised at similar sites to those of the physiologically occurring amine. … Lire la suite

2005 — Plasticity of sodium currents as a mechanism for temporal lobe epilepsy originating from within the entorhinal cortexRésumé
The main goal of this dissertation is to explore the hypothesis that persistent sodium currents may mediate epileptogenicity within the entorhinal cortex. The thesis attempts to answer three major questions: First, it asks whether persistent sodium currents regulate intrinsic excitability of entorhinal cortical layer V, which has been demonstrated to exhibit epileptogenic characteristics. Second, it asks whether persistent sodium currents may be up-regulated in an acquired temporal lobe epilepsy rodent model (lithium-pilocarpine), whose features strongly correlate with human temporal lobe epilepsy. Third, it asks whether persistent sodium currents may be up-regulated in a genetic epilepsy model, which overexpresses a mutation … Lire la suite

1997 — Modeling of solidificationRésumé
Some models of solidification are developed by treating the solid in a more realistic manner than that has been done to date. In order to further investigate the polymorphous dendritic growth, a recent phase-field model of dendritic growth due to Kobayashi [93] is modified by introducing a vectorial order parameter. This new model allows for the existence of grain boundaries and is used to study the amorphization of polycrystalline material as well as the growth of many dendrites of different orientations. One of the major techniques of solidification, namely the directional solidification is further analyzed by using the phase field … Lire la suite

2007 — Applications of mass spectrometry in clinical chemistry and biomedical researchRésumé
Clinical chemistry is a medical discipline whose aim is to diagnose and assess disease by analysis of biological specimens. Modem laboratories can perform several hundred different tests using many different methods developed over the last century. The classical, more traditional assays are typically labour-intensive, not multiplexed (only measure one analyte or disorder per assay), expensive, require a long turnaround time, and may not provide adequate sensitivity and specificity. Developments in mass spectrometry (MS) and related technologies over the last two decades have provided solutions for many if not all of these shortcomings. While MS based applications have not yet been … Lire la suite

2002 — Air carrier liability and automation issuesRésumé
Our intended topic is a general discussion of the basic elements of liability related to airline accidents to which fully automated cockpits have constituted an associated contributory factor. In addition we addressed the liability of air carriers arising from injuries or death caused to passengers traveling on international flights. For this purpose, we reviewed the Warsaw System and the different international instruments that constitute it. We also reviewed principles of common law applicable to aircraft manufacturers and the "Free Flight" as an example of the growing automation environment, which is a general benefit to commercial aviation but also a likely … Lire la suite

2017 — Resourcing for inclusion in transnational governance: the work of indigenous peoples in the Nagoya protocolRésumé
La recherche existante suggère la prolifération de nouvelles formes d'institutions globales qui régulent, orientent et surveillent les interactions et les activités sociales à travers différents territoires nationaux dans les dernières années. Ce phénomène est accompagné des efforts des acteurs 'non état' pour influencer dans ces régulations globales. Par contre, on sait peu sur ce que les communautés affectées par ces régulations font pour devenir de participants actives dans le processus de gouvernance globale, même ayant accès à des ressources limitées. Comment des acteurs marginalisés travaillent pour leur inclusion dans le processus de création de nouvelles institutions globales ? Cette thèse … Lire la suite

2018 — Modeling and simulations of defect-free collagen film formation process and biological plywood morphology analysisRésumé
This thesis uses multiscale computational modeling, scaling and analysis to characterize the steps of a multistage process used to produce a defect-free cholesteric collagen film and to characterize the resulting chiral biological plywood microstructure, found throughout Nature. The process makes use of a complex flow deposition of a liquid film of a dilute collagen solution on a substrate which is later converted to a chiral biological plywood by exposure to an airflow of filtered air. During the flow deposition analysis and simulations, two crucial material properties are estimated: the rheological shape parameter β and the rotational diffusivity Dr; the former … Lire la suite

2000 — Preparation and characterization of rapid solidified yttria-alumina fibersRésumé
A melt extraction process with a new approach to making ceramic fibers was used to produce amorphous fibers in the Y2O3-Al 2O3 system within the 20--30 micron size range. Three different compositions were studied, E1, Y3A5 and E2 with 79, 62.5 and 57.5 mol% Al2O3, respectively. Such fibers were X-ray amorphous and transparent, regardless of composition in the as-produced state, and showed all the principal characteristics of the fibers made by this process: a cross section which is almost circular, a line of contact with the wheel and a clean and defect-free surface. However, the quality of the fibers was … Lire la suite

2011 — Prenatal inflammation and neurodevelopmental disorders: The role of cytokinesRésumé
L'infection chez la mère a été liée au développement de la schizophrénie chez l'enfant, probablement due à la réponse inflammatoire déclenchée par l'infection. De nombreuses études utilisant des modèles animaux ont démontré que l'inflammation est suffisante pour déclencher des altérations dans le cerveau chez la progéniture adulte, en particulier dans le système dopaminergique mésolimbique (DA), impliqué dans la physiopathologie de la schizophrénie. L'objectif de ce programme de recherche était d'identifier quels éléments de la réponse inflammatoire sont impliqués dans les changements observés dans la neurotransmission DA de la progéniture. La cytokine pro-inflammatoire interleukine (IL)-6, l'antagoniste du récepteur de l'IL-1 (IL-1ra) … Lire la suite

2004 — Stress response mechanisms during rat spermatogenesis and the effects of the anticancer agent cyclophosphamideRésumé
Exposure of males to drugs or environmental chemicals can alter reproductive health and affect progeny outcome. The quality of the male germ cell is determined in part by the presence and function of stress response mechanisms. During spermatogenesis, different germ cell types display differential susceptibility to toxicants, suggesting there is variation in the presence and function of stress response mechanisms. Exposure of male rats to cyclophosphamide, a commonly used anticancer and immunosuppressive drug, alters male fertility and progeny outcome in a male-germ cell phase specific manner. The hypothesis of this thesis is that stress response mechanisms are differentially expressed during … Lire la suite

1958 — The role of chronic encephalitis in the pathogenesis of epilepsy.Résumé
This paper presents histopathological evidence that chronic encephalitis may play a pathogenetic role in some cases of focal cerebral seizures. Correlation of the pathological findings with the clinical picture in such cases demonstrates a fairly constant interrelationship. Furthermore, the clinical data, including the history, physical findings, electroencephalographic and radiological studies, laboratory findings, psychological test data, findings at surgery, and follow-up information, suggest a unique clinical syndrome.

1999 — Supranational systems of dispute resolution and their integration into domestic legal systems : a view of the Latin American ExperienceRésumé
The influence of globalization over legal systems has resulted in, among other effects, the emergence of transnational law and new international players, such as multinational corporations (MNEs), non-governmental organizations (NGOs) and numerous international entities. The dynamics of the new players within the new transnational legal order have generated a need for a new supranational system of dispute resolution. The analysis focuses on the Latin American experience in adapting to judicial reform programs (sponsored by international organizations such as the World Bank and the International Development Bank) which promote the integration of Alternative Dispute Resolution (ADR) methods into domestic legal systems, … Lire la suite

2021 — Understanding and amplifying the experiences of students with disabilities: A study of self-determination and the quality of student life in post-secondary settingsRésumé
Au cours des deux dernières décennies, la pratique et la recherche se sont progressivement déplacées des modèles de dysfonctionnement, de déficits et de ségrégation vers des points de vue et des attitudes qui reflètent plutôt l'inclusion, la visibilité et le plaidoyer (Wehmeyer, 2004). Suite à ces changements, la qualité de vie (QV) et l'autodétermination (DS) sont apparues comme des concepts importants pour saisir cette vision changeante et offrir des cadres plus holistiques et complets permettant d'étudier les expériences hétérogènes et uniques des étudiants handicapés (Wehmeyer et Schalock, 2001). Bien que les inscriptions d'étudiants avec handicapes dans les milieux postsecondaires aient … Lire la suite

2015 — The relations between bullying behaviour and quality of student life among secondary students in a northern Quebec communityRésumé
Cette étude porte sur l'étude du lien entre le bullying scolaire (intimidation scolaire) et la qualité de la vie étudiante chez les adolescents. Les comportements d'intimidation (par exemple, l'intimidation et la victimisation) ont été analysés en utilisant le Questionnaire Agresseur/Victime d'Olweus (AVO). La qualité de la vie étudiante (QDVE), a été mesurée par quatre sous-échelles du questionnaire QDVE (la satisfaction, le bien-être, l'appartenance sociale et l'auto-détermination/contrôle). Un groupe de 33 élèves provenant d'une école secondaire dans le nord du Québec a participé à l'étude. Les résultats ont indiqué que les étudiants qui ont déclaré avoir été victimes d'intimidation ont également … Lire la suite

2011 — Parkin interacts with the 26S proteasome via Rpn13, a novel ubiquitin receptorRésumé
Mutations in the Parkin gene cause a juvenile-onset for of Parkinson's disease (PD) that is transmitted in an autosomal recessive way. Studies have shown that mutations in parkin account for almost 50% of all juvenile-onset forms of PD, making parkin one of the most studied genes as a causative factor for PD.Ubiquitin (Ub), a small 76 amino acid protein, can be covalently attached to other proteins. This post-translational modification is used as a signal for degradation in the ubiquitin-proteasome pathway (UPP). Ubiquitination requires the concerted activity of 3 basic enzymes: Ub-activaying enzyme (E1), Ub-conjugating enzyme (E2) and Ub-ligase (E3).Studies have … Lire la suite

1996 — Food of the GodsRésumé
The thesis is a short novel, Food of the Gods, followed by a critical afterward and bibliography. In Food, four graduate students, all to varying degrees perverse, come together in a cabalistic union. Bored and desperate, they begin to transgress a series of taboos, eventually performing communal acts of aggression, murder, and even cannibalism. Frank West, one of the students, is the novel's narrator and questionable moral center. It is through his confession that the four's "monstrous deeds" are filtered through. Thematically, Food examines the potential for evil in individuals, as well as the group dynamics which encourage such acts … Lire la suite

2026 — Stigma of Psychosis in Indonesia: Exploration of Perceptions and Subjective ExperiencesRésumé
RésuméLa stigmatisation entourant la psychose a un impact significatif sur l'accès aux services de santé mentale en Indonésie, touchant à la fois les personnes atteintes de psychose et leurs aidants familiaux. Les idées fausses courantes sur la psychose entraînent souvent des perceptions de violence et de danger, ce qui conduit à l'intériorisation de la stigmatisation chez les personnes concernées. Parallèlement, les aidants familiaux subissent également une stigmatisation qui affecte négativement leur bien-être émotionnel. Malgré les contextes culturels et spirituels qui façonnent ces expériences, il existe une brèche dans les connaissances concernant les recherches empiriques à propos de la stigmatisation en … Lire la suite

1993 — Comparison of two nutrient admixtures for total parenteral nutritionRésumé
The goal of Total Parenteral Nutrition (TPN) is to provide protein and non-protein energy in order to promote nitrogen retention and meet energy requirements. Controversy exists on whether glucose or lipid is the optimal source of non-protein energy. A randomized clinical trial was conducted for one week to compare the effects of TPN providing 34% of non-protein energy as lipid (Group 1; n = 7) to those of hypertonic glucose TPN (Group 2; n = 6). Indices of nitrogen retention, metabolic abnormalities, physiologic stress, and fat clearance were measured. The energy and protein intakes of Group 1 exceeded those of … Lire la suite

2018 — Actions louder than words: reading narrative silence as literary creation in the BrontësRésumé
The purpose of this study is to interrogate how women's silences in Victorian literature, and in the Brontë canon more specifically, are calculated to facilitate female expression through diverse modes of creative and expository narrative. As a response to second-wave feminist scholarship and its emphasis on female silence as oppressive, this thesis considers the role of metafiction in Charlotte Brontë's Jane Eyre (1847), Emily Brontë's Wuthering Heights (1847), and Anne Brontë's The Tenant of Wildfell Hall (1848), in order to refocus attention from their heroines' subdued dialogue to more forceful, and often covert, forms of narrative control. Each chapter centers … Lire la suite

2024 — An analysis of cognitive-related and lifestyle-related microstructural variations in the human hippocampus: An Ageing StudyRésumé
Ageing is a biological process associated with the natural degeneration of various regions of the brain. Alteration of neural tissue in the hippocampus with ageing is typically associated with cognitive decline that may serve as a risk factor for dementia and other neurodegenerative diseases. Modifiable lifestyle factors may help preserve hippocampal neural tissue (microstructure) and slow down neurodegeneration and thus promote healthy cognition in older age. In this thesis, we sought to identify potential modifiable lifestyle factors that may help preserve microstructure in the hippocampus. We used 494 subjects (36- 100), without pathological cognitive impairment, from the Human Connectome Ageing … Lire la suite

2026 — A regional exploration and assessment of the role of feed additives towards lower emissions from livestock agrifood systemsRésumé
Livestock production, particularly feed and manure management, accounts for a major share of this impact. Within this context, feed additives have emerged as a key mitigation pathway. Therefore, this dissertation first assessed the environmental footprint of producing commercial feed additives in Canada, identified impact hotspots and explored alternative strategies to inform eco-design. It then evaluated how nutritional strategies with vs without the supplementation of feed additive such a protease, rumen-protected B vitamins (RPBV), and protected organic acids and essential oils [P(OA+EO)], could reduce the environmental impacts of livestock production while optimizing performance. These findings were further integrated into a decision … Lire la suite

1999 — Between duty and desire : sentimental agency in British prose fiction of the later eighteenth centuryRésumé
This dissertation investigates the properties of sentimentality by analyzing the move in British literature from a fascination with heightened affect to a celebration of Gothic excess during the period 1768--1796. This study develops an account of sentimentality as a model of agency, theorizes the relationship of sentimental ideology to sentimental narrative form, and traces continuities between the sentimental and Gothic modes through an examination of texts that share a preoccupation with the aesthetics and ethics of sentimentalism. By examining representations of sentimental agency in prose fiction narratives by Laurence Sterne, Henry Mackenzie, Ann Radcliffe, and Matthew Lewis, this dissertation argues … Lire la suite

2022 — Annotation of ancient mammalian repetitive elements though ancestral genome reconstructionRésumé
Au cours des dernières décennies, les technologies de séquençage avancées et la disponibilité de séquences génomiques ont rendu possibles des études à l'échelle du génome. Néanmoins, comprendre la structure et la fonction des éléments génomiques, ce qu'on appelle l'annotation du génome, reste un défi majeur. La génomique comparative joue un rôle essentiel dans l'annotation précise du génome et dans la compréhension de divers éléments génomiques tels que les éléments transposables (ET) et les pseudogènes, entre autres. L'impact de ces composants dynamiques sur la structure et l'évolution du génome ainsi que leurs contributions à la formation d'autres éléments fonctionnels ont suscité … Lire la suite

2015 — Ancient transposable elements discovery and annotationRésumé
Les éléments transposables (ET), la plus grande classe de fragments d'ADN répétitif, sont les éléments les plus abondants du génome de la plupart des eucaryotes. Leur nombre même, leur mécanisme de transpositions et leur nature répétitive sont responsables de certains défis importants en génomique, et c'est en partie ce qui les rend particulièrement intéressants à étudier. L'avenue récente des technologies de séquençage et la disponibilité de séquences génomiques a rendu possible l'analyse de ETs dans des génome entiers. L'impact des ET sur la structure, l'évolution et la taille du génome ainsi que le séquençage du génome et l'annotation a suscité … Lire la suite
