    1999 — Children's winter sports injuries & protective equipment : a surveillance system based study
    Abstract

    Sports injuries that could be prevented by protective equipment are a serious cause of morbidity among children. The objectives of this study were to: determine the frequency of protective equipment use among children participating in winter sports, identify the reasons for non-use of equipment, explore whether an injury prompted an intended change in the use of protective equipment, and compare an open-ended and a categorical method for collecting data on sports injuries. Data was collected about children who visited the emergency rooms of the Montreal Children's Hospital and L'Hopital Ste. Justine, from the Canadian Hospitals Injury Reporting and Prevention Program, …  Read more

    2008 — Blind channel estimation and single-user detection for multi-carrier and spread-spectrum systems with transmit diversity
    Abstract

    The application of transmit diversity techniques such as Space-Time Block Coding (STBC) to the downlink of multiuser wireless communications systems has received considerable attention. The main advantage of such an approach is its ability to provide diversity gains through the use of multiple antennas only at the transmitting side without significantly increasing the complexity at the receiving end. Among the many multiple access techniques proposed, Multi-Carrier (MC) and Direct Sequence (DS) Code Division Multiple Access (CDMA) techniques are known as the most promising candidates for future broadband mobile communication networks. In MC and DS-CDMA systems or combination thereof, employing transmit …  Read more

    1991 — Autonomic and pharmacologic modulation of the frequency-dependent properties of the atrioventricular node
    Abstract

    The responses of the atrioventricular node (AVN) to changes in activation rate is complex. A variety of approaches have been used to explain the different responds of AVN, but none has been able to describe fully nodal behavior. Three rate-dependent nodal properties referred to as recovery, facilitation, and fatigue contribute to rate-induced changes in nodal conduction time. We developed a model incorporating a quantitative description of these properties that was able to accurately predict AV node conduction during steady state atrial pacing. This model provides a mathematical framework through which interventions such as changes in the autonomic tone may affect …  Read more

    2000 — Lung fibre concentration, dimension, and asbestosis severity : relationships among Québec chrysotile miners and millers
    Abstract

    The objectives of this study were: (1) to compare lung fibre concentration and dimensions found in two groups of former Quebec chrysotile miners (Asbestos and Thetford-Mines) and, (2) to investigate the relationship between lung-retained mineral fibre concentration and dimension (length, diameter, and aspect ratio) to severity of interstitial lung fibrosis (asbestosis) within these groups. Lung fibre content was determined for 86 former employees of chrysotile mines and mills in two Quebec mining regions: Thetford-Mines and Asbestos (Jeffrey Mine). Six lung samples were selected for each subject from predetermined intrapulmonary sites. In summary, the concentrations of tremolite for short (<5 mum) …  Read more

    1992 — Enzymatic hydrolysis of shrimp for recovery of taste active compounds
    Abstract

    The muscle of shellfish, in particular shrimp, is characterized by high amounts of free amino acids especially glycine as well as proline, serine and alanine which all contribute to the overall pleasant and desirable flavour perceived. The two major proteolytic enzymes, chymotrypsin and trypsin, were used at different ratios (E/S, 0.0-0.3%), temperatures (25$ sp circ$C-45$ sp circ$C) and time of hydrolysis (1-3h) for frozen and fresh shrimp. These conditions were optimized in order to generate a product with desirable sensory and chemical characteristics. The thermal stability of chymotrypsin and trypsin were investigated, to determine the suitability of heat to stop …  Read more

    2002 — A process comparison algorithm /
    Abstract

    The purpose of this research was to design a method for the detailed comparison of processes. People already do process measurement and compare these measurements to internal or regulatory standards. The innovation in this thesis is the development of an algorithm for process comparison that accommodates any process, responds to any kind of semantic junction in the process model, deals with uncertain process data, and compares all or part of a process. This is done by the activity-by-activity comparison of data and measurements from an actual process to a model of a process. IDEF3 diagrams were used for process modeling, …  Read more

    2001 — Literature at lightspeed: a community of writers on the world wide web and its relationship to the print publishing industry
    Abstract

    L’Internet offre aux écrivains de nouvelles possibilités de réalisation et de distribution de la littérature contemporaine. Cette dissertation commence par examiné en profondeur l’identité de ces écrivains, ce que font ces écrivains et les avantages et les désavantages du Web en comparaison avec les méthodes d’édition traditionnelles. Etant donné les réseaux qui se produisent et l’existence d’objectifs communs parmi les écrivains, on s’aperçoit qu’une véritable communauté d’auteurs s’est développé sur le Web. Ceci dit, aucune communauté n’existe indépendement d’autres facteurs sociaux qui l’influencent. Les sociétés de divertissement multinationales, par exemple, essaient de changer la structure fondatrice de ces technologies pour …  Read more

    2016 — Computed basis functions for nonconforming voxel finite element methods in electromagnetics
    Abstract

    La méthode des éléments finis de voxel non conforme (NVFEM ou Nonconforming Voxel Finite-Element Method) permet d'éviter un grand nombre des difficultés de maillage traditionnel en utilisant un réseau imbriqué d'éléments finis cubiques. Son principal inconvénient est la nécessité de rapprocher les limites qui, autrement, passeraient à travers l'intérieur des éléments, ce qui entraîne une perte de précision et une convergence lente. Dans cette thèse, une technique appelée la méthode de fonction de base calculée (CBF ou computed basis function) est appliquée, ce qui permet les discontinuités de matériel dans les éléments. Dans la CBF-NVFEM, une maille temporaire locale de …  Read more

    2017 — Symplectic cohomologies and Hodge theories
    Abstract

    Cette thèse reprend les théories de cohomologie symplectique de Tseng et Yau, qui fournissent des analogues symplectiques des cohomologies de Dolbeault, Bott-Chern et Aeppli pour les variétés complexes. Les propriétés de base de ces cohomologies, telles que leurs théories de Hodge, la finitude de leurs dimensions, leurs propriétés de dualité et les lemmes de Poincaré sont étudiés. Les cohomologies symplectiques sont calculées explicitement dans le cas des fibrés cotangents. Bien que cette thèse ne contienne pas de résultats nouveaux, elle contient des preuves détaillées de certains résultats qui sont énoncés sans preuve dans les travaux de Tseng et Yau.

    2024 — The potential role of a PGPR-produced bacteriocin for sustainable agriculture: assessment of Thuricin 17 efficacy on canola production
    Abstract

    Le canola (Brassica. napus), l'une des principales cultures oléagineuses, est largement cultivé dans le monde entier. Cependant, la productivité des cultures de canola a diminué dans des conditions stressantes dues au changement climatique. Il est donc essentiel de développer des stratégies durables pour aider les plantes à faire face aux facteurs de stress environnementaux. Les micro-organismes favorisant la croissance des plantes (PGPMs) et les composés spécifiques qu'ils produisent pourraient avoir la capacité d'atténuer les effets néfastes des conditions de stress sur les plantes. Un exemple dans ce contexte est la Thuricine 17 (Th17), une bactériocine produite par Bacillus thuringiensis NEB17 …  Read more

    2014 — Investigation of the role of gamma-tubulin phosphorylation in regulation of spindle assembly
    Abstract

    La formation d’un fuseau mitotique complet, avec des microtubules attachés aux kinétochores ou associé à un microtubule antiparallèle, est essentielle au processus de ségrégation des chromosomes. La première étape de ce processus est la nucléation des microtubules depuis la duplication des pôles des fuseaux. Dans la levure, Saccharomyces cerevisiae, les fuseaux des microtubules sont initiés et construits à partir d’anneaux de gamma-tubulines composés de gamma-tubulines et de protéines interagissant avec les gamma-tubulines (GRIP) localisés dans le centre d’organisation du microtubule (MTOC) fongique, appelé le corps polaire du fuseau.

    1963 — Evoked response pattern and recovery cycles in human subjects.
    Abstract

    By definition evoked potentials are "the detectable electrical changes in the brain in response to deliberate stimulation of any part of the nervous system” (16). The importance of recording human brain responses to controlled sensory stimuli is well recognized. These responses represent, in fact, the end product of a long series of events in the nervous system from the peripheral receptor organs, through many interneurones and relay stations, up to the cortical neurons which participate in their production. Any change, physiological, chemical or pathological, occurring anywhere along their paths may be reflected in the recorded evoked responses. It is conceivable, …  Read more

    1983 — A rule-based expert system for image segmentation /
    Abstract

    A major problem in robotics vision is the segmentation of images of natural scenes in order to understand their content. This thesis presents a new solution to the image segmentation problem that is based on the design of a rule-based expert system. General knowledge about low level properties of an image is formulated into production rules. A number of processes employ the rules to segment the image into uniform regions and connected lines. In addition to the knowledge rules, a set of control rules are also employed. These include meta-rules that embody inferences about the order in which the knowledge …  Read more

    2015 — Unit commitment with sub-hourly generation and ramp constraints for systems with significant renewables
    Abstract

    With significant growth in wind generation in the recent years, addressing the challenges related to integration of wind into power systems has become an important area of research. In power systems, generation and demand must always balance. There must also be enough reserve generation capacity to meet fluctuations in load and renewable sources. Based on the 24 hour demand and wind forecasts, system operators schedule the generation and reserve by solving a day ahead Unit Commitment (UC). During operations, the generators must respect the trajectory limits set by UC. While having too much reserve is expensive, having less of it …  Read more

    2015 — The effect of internal and external electronic integration on business unit agility
    Abstract

    Agility - the capability of organizations to sense and respond to market opportunities and threats with speed and surprise - is quickly becoming an essential element for companies to effectively compete in hypercompetitive environments. At the same time, firms are using applications that enable close integration among organizational units. Current environment necessitates that firms pursue agility as well as tight integration. However, we still do not understand how integration affects agility. Although the literature suggests that integration enables digital options that facilitate agility, it is not clear what specifically those digital options are and how do they inform the integration-agility …  Read more

    1988 — Studies on the immunobiology of trypanosoma lewisi infections in rats
    Abstract

    The immunological responses in hosts infected with Trypanosoma lewisi were examined during the course of infection and after recovery. Peak antibody levels coincided with the time of parasite elimination, but remained significantly elevated for over one year after the end of the infection The antigen repertoire recognized by antibodies demonstrated that some were revealed only by sera taken during the infection, and other antigens were revealed for the first time only by post-recovery sera. Immunomodulatory protective and suppressive factors were demonstrated in the plasma of irradiated, infected rats. These factors were identified as parasite-derived exoantigens which are shed in vivo …  Read more

    2001 — Agricultural productivity and rural-urban migration : the case of Senegal
    Abstract

    Rural-urban migration in Sub-Saharan African countries has been increasing since the 1960s. In Senegal from 1961 to 1996, it grew 7.6% per annum. Labour market in the modern industrial and service sectors is so depressed that urban workers face high unemployment and poverty rates, and live in substandard conditions in the fringe urban sector. The purpose of this study is to examine policies needed to reduce rural-urban migration through selected agricultural investments, especially given that a long run of low agricultural productivity has been a major cause of rural-urban migration flows. Based on a recursive system of equations, an estimate …  Read more

    2010 — Phenotypic and functional characteristics of CNS CD8+ T cells mediating a demyelinating disease
    Abstract

    We reported that transgenic mice constitutively expressing the B7.2 (CD86) T cell costimulatory ligand on microglia spontaneously develop a T cell-mediated demyelinating disease. We have shown that CD8+ T cells are the primary effector T cell-subset that initiates the pathological process. This demyelinating disease appears to be initiated by the activation antigen-specific CD8+ T cells within the central nervous system (CNS) and shows a complete dependence on IFN-gamma receptor signalling. To further understand the pathological process that occurs in this animal model, we characterized the phenotypic and functional status of the CD8+ T cells that accumulate/expand in the CNS. Our …  Read more

    2004 — Male germ cell development in the methylenetetrahydrofolate reductase (MTHFR) mouse model
    Abstract

    Methylenetetrahydrofolate reductase (MTHFR) catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, a substrate for remethylation of homocysteine to methionine. Methionine is then converted to S-adenosylmethionine (SAM), the universal methyl donor. In the mouse, MTHFR levels are highest in the testis and mice deficient for a targeted mutation in the Mthfr gene are infertile. Analysis of prenatal gonocyte development provided evidence that the defect in the Mthfr mouse testis occurs shortly after birth. The expression profiles at the mRNA and protein levels suggest that Mthfr is expressed in the male germ line and is developmentally regulated, with a possible role in meiosis. …  Read more

    2003 — Meanings of masculinity in late medieval England : self, body and society
    Abstract

    Masculinity is a set of meanings, and also an aspect of male identity. Understanding masculinity in history, therefore, requires attention to culture and psychology. The concept of a "crisis of masculinity" cannot address these dimensions sufficiently and is of little use to the historian. This analysis of evidence from late medieval England begins with the social world. Legal records show men defending, and therefore defining, masculine identity through interaction among male peers and with women. Defamation suits suggest a fifteenth-century identification of masculinity with "trueness": an uncomplicated, open honesty. A "true man," in late medieval England, was not just an …  Read more

    1993 — Characterization of the neural cell adhesion molecule N-CAM in splotch mutant mouse embryos
    Abstract

    Cell adhesion molecules are known to play crucial roles in a variety of developmental processes. The neural cell adhesion molecule N-CAM is strongly implicated in neurulation and neural crest cell (NCC) migration and was thus studied in splotch (Sp) neural tube defect mutant embryos. At the 20 somite-stage of gestation day 9, Sp N-CAM was found to contain polysialic acid (PSA) side chains which are normally only present beginning at gestational day 11. Younger embryos at 12 and 14 somites also showed the presence of PSA on N-CAM, which was absent in controls. Enzymatic removal of PSA from N-CAM resulted …  Read more

    2016 — Role of histone methylation in the regulation of tumour suppressor networks
    Abstract

    Cellular senescence is a tumour suppressor mechanism which prevents the proliferation of malignant cells. In normal cells, oncogenic stimuli induce a senescence response and growth arrest coordinated by tumour suppressor genes, but the loss of expression of these genes impairs the establishment of senescence in cancer cells. We studied the role of histone methylation and oncogenic histone modifiers to assess their responsibility throughout the bypass of tumour suppressor pathways. We first used a PRMT6 knock-out mouse model to recognize the potential effect of PRMT6-mediated histone arginine methylation in cancer. Herein, we report that PRMT6 catalyzes the asymmetric di-methylation of histone …  Read more
