    1996 — Chiral nematic ordered suspensions of cellulose microcrystallites
    Résumé

    Suspensions of rod-like cellulose microcrystallites, 50-250 nm in length and $ sim$7 nm in width, and with negatively charged sulfate groups on the surface have been prepared. When the concentration of cellulose microcrystallites exceeds a critical value, the suspension separates into two phases, forming an upper isotropic phase and a lower chiral nematic anisotropic phase. The critical concentration for phase separation is very sensitive to the ionic strength, particle size, polydispersity of particles, counterion species, and preparation conditions. When the suspension is in pure water and in the biphasic region, the coexisting concentrations in both phases increase with the increase …  Lire la suite

    1996 — Modification of intermediate filaments in motor neurons and other cells by activation of protein kinase C
    Résumé

    The effects of activation of protein kinase C (PKC) on intermediate filaments (IFs) of different cell types were investigated. In primary cultures of murine or rabbit spinal cord, or human fibroblasts, brief exposure to activators of PKC led to the following changes in IFs: (1) Disassembly of GFAP-filaments in astrocytes and of vimentin in fibroblasts and fragmentation of the neurofilament (NF) network in neuronal cell bodies (occurred within 30 minutes). The distribution of PKC isoforms was investigated in these cell types and no IF-associated isoform was found. Disassembly of IFs may be explained by direct phosphorylation of N-terminal domains of …  Lire la suite

    1996 — Securities regulation in Canada : status, issues and prospects
    Résumé

    Canada's fragmented, provincially-based securities regulatory system is facing domestic and international pressures to become more coherent and efficient. This paper outlines various factors and proposals, concluding that the system must become nationally-based, but only if the change is properly planned, implemented and administered. There should be uniform (or, at least, coordinated) legislation, with federal and provincial joint delegation to a single commission. Interprovincial coordination must improve before, during and after the change. While feasibility requires most provinces to participate, the scheme should not be rejected if unanimity is lacking. Although important, regional autonomy cannot be allowed to outweigh national authority. …  Lire la suite

    1996 — Coming into site : identity, community and the production of gay space in Montréal
    Résumé

    This project explores the question of gay male identity and community formation in relation to the production of social space designated as "gay." What economic, social, political and symbolic resources are involved in the production of gay space? And how can social space be thought of as creating the conditions of possibility for the formation of specific gay identities and communities? Using a "production of space" analysis adapted from the work of Henri Lefebvre, I examine the case of Montreal's gay village. I argue that the emergence of this space, in both material and symbolic terms, has led to a …  Lire la suite

    1996 — Seasonal structure of the Gulf of St. Lawrence upper-layer thermohaline fields during the ice-free months
    Résumé

    The interactions between the atmosphere and the oceans play a critical role in determining our climate. These generally consist of various exchanges of heat, mass and momentum between the two media through the air-sea interface. Therefore, the physical state of the upper few meters of the oceans influences the rate at which these exchanges take place. Furthermore, these surface waters are of importance in affecting the primary biological production of the seas. In this context, knowledge of the upper-layer monthly averaged thermohaline state, i.e. temperature (T) and salinity (S) as a function of latitude-longitude and depth, is necessary for further …  Lire la suite

    1996 — The ambient pressure precipitation of crystalline scorodite (FeAsO4.2H2O) from sulphate solutions
    Résumé

    Arsenic extraction and immobilization from hydrometallurgical solutions and effluents is usually achieved by ferric arsenate precipitation. An alternative vehicle is proposed in the form of crystalline ferric arsenate, or the mineral scorodite (FeAsO$ sb4$.2H$ sb2$O). The precipitation of scorodite from sulphate-based effluents at ambient pressure (95$ sp circ$C) was investigated using a supersaturation controlled precipitation technique. This technique has been used to precipitate scorodite from chloride-based solutions. Test work using NaOH showed that amorphous ferric arsenate precipitation was avoided even at very high supersaturation levels ($>$70). This was in sharp contrast with the results obtained in the chloride system (supersaturation …  Lire la suite

    1996 — Characterization of a novel cardiac chloride channel and its regulation by cell volume and protein kinase C
    Résumé

    The cardiac action potential is generated and regulated by currents through various ion channels. Ion channels are membrane-spanning proteins involved not only in the conduction of electrical impulses but also in the control of cell homeostasis such as cell volume to maintain normal physiological conditions. While chloride (Ct) channels have been found to be present in the plasma membrane of most cells, the role of these channels in cardiac physiology is poorly understood. Since the discovery of a cAMP-activated Cl· current (lcI.cAMP) in heart in 1989, renewed interest in cardiac Cl- channels has emerged. […]  Lire la suite

    Mesure, dimension et complexité sont des notions liées et leur apparentement s'avère important tant au niveau pratique que théorique. Les mesures pour les courbes du plan peuvent inclure leur longueur, le nombre de composantes, ou l'aire couverte. En géométrique différentielle, les courbes planes sont caractérisées comme étant une application de l'intervalle au plan. En topologique, elles sont caractérisées comme un espace de Hausdorff avec certaines propriétés de dénombrement. Aucune de celles-ci ne capture vraiment l'essence de ces courbes en vision cependant, c'est-à-dire qu'elles puissent représenter des objets simples, comme un segment de droite, ou des objets compliques, comme un paquet …  Lire la suite

    1996 — Techniques for rainfall estimation and surface characterization over northern Brazil
    Résumé

    The sertao of northeast Brazil is a semiarid region characterized by recurring droughts. The vastness of the area (650,000 km$ sp2)$ poses a challenge to the effective monitoring of the impacts of drought at a scale that would be useful to the inhabitants of the sertao. Remote sensing data provide a viable way of assessing the extent and nature of drought across the landscape. The work present a more effective algorithm to estimate rainfall from both the cold and warm cloud types present. Using a decision-tree methodology, the analysis yields rainfall estimates over the 0-21 mm range. Because seasonal variations …  Lire la suite

    1996 — Molecular basis of biotin-responsive multiple carboxylase deficiency
    Résumé

    Multiple carboxylase deficiency (MCD) results from a decreased activity of holocarboxylase synthetase (HCS) which is responsible for the biotinylation of the four biotin-dependent carboxylases found in humans. The disease can be treated with pharmacologic doses of oral biotin (biotin-responsiveness). The cDNA for HCS contains a biotin-binding domain deduced by analogy with the sequence and crystal structure of the E. coli BirA biotin ligase. E. coli birA$ sp-$ mutations causing biotin-auxotrophy all localize to this region. Of six point mutations I have identified in MCD patients, four localize to the biotin-binding region. In order to assess the HCS activity associated with …  Lire la suite

    1996 — Principles of energy and momentum conservation to analyze and model air flow for perforated ventilation ducts
    Résumé

    A theoretical model was developed to predict the air distribution pattern and thus to design perforated ventilation ducts equipped with a fan. The analysis of the air distribution pattern of such systems requires accurate measurement procedures. Several experimental methods were tested and compared. Accordingly, the piezometric flush taps and thermo-anemometer were selected to measure respectively the duct air pressure and the outlet air flow. Based on the equations of energy and momentum conservation, a model was formulated to predict the air flow performance of perforated ventilation ducts and to evaluate the outlet discharge angle and the duct regain coefficients without …  Lire la suite

    1996 — Human rights and cultural diversity in Islamic Africa
    Résumé

    This thesis establishes a framework for analysing and evaluating human rights within the contexts of global, African-Islamic and Sudanese cultural diversity. The normative impact of culture on international human rights is viewed from the perspective that culture is adaptive and flexible. African-lslamic culture, as exemplified by the Sudan, is no exception. The first part of this thesis advances a theoretical framework for recognition of cultural diversity and its impact on human rights. Recognition of change as an integral part of culture is vital for a successful mobilisation of internal cultural norms to the support of international human rights. An important …  Lire la suite

    1996 — Implementing event handlers in a database programming language
    Résumé

    This thesis introduces active database concepts to a relational database system. Event handlers are introduced as user defined procedures. An event is the procedure call by the system, triggered in our case by an update statement. Event handlers for the Relix (Relational database on UNIX) update statement have been implemented. These event handlers are of two types: the first type is that which runs before an update statement. The second type runs after an update statement. Also, event handlers have states. An event handler can be either active or inactive. Event handlers are executed when they are in the active …  Lire la suite

    1996 — Dynamic load balancing for clustered time warp
    Résumé

    In this thesis, we consider the problem of dynamic load balancing for parallel discrete event simulation. We focus on the optimistic synchronization protocol, Time Warp. A distributed load balancing algorithm was developed, which makes use of the active process migration in Clustered Time Warp. Clustered Time Warp is a hybrid synchronization protocol; it uses an optimistic approach between the clusters and a sequential approach within the clusters. As opposed to the centralized algorithm developed by H. Avril for Clustered Time Warp, the presented load balancing algorithm is a distributed token-passing one. We present two metrics for measuring the load: processor …  Lire la suite

    1996 — Evidence of speed gradient sensitive neurons in the monkey extrastriate area MSTd
    Résumé

    Optic flow is the changing array of light that is reflected from objects in the environment and is projected on the retinae during motion. Speed gradients are a natural component or optic flow and they are the result of the relative ordering of objects in depth. It has been proposed that speed gradient information may signal the direction and speed of self-motion as well as the three-dimensional structure of the environment. The dorsal region of the medial superior temporal area of the visual cortex, or MSTd, is believed to be the neuronal basis for the analysis of optic flow and …  Lire la suite

    1996 — Categorical perception in bilingual and monolingual adults
    Résumé

    The categorical perception paradigm was used to compare French/English bilinguals' and French and English monolinguals' categorization of code-switched words. A previous study by Burki-Cohen et al. (1987) showed that bilinguals' categorization of a cross-language continuum that varied from a French word to an English word was different when the words were presented in the context of a French or an English carrier phrase. Using the same stimuli the present study examined whether the effects of base language (i.e. the carrier phrase) are due to processing specific to bilinguals or are mediated by general phonetic or auditory processes. Results showed that …  Lire la suite

    1996 — Aspects of power domains and power locales
    Résumé

    Several equivalent approaches to power domains are presented: the naturality of this concept for denotational semantics is stressed and its modal interpretation is explained. We show how to solve equations involving power domains and apply the theory to an equation that leads to a characterization of bisimulations. Power locales are introduced, as the analogue of both power domains and power spaces. We study the monads defined by the power locales, their algebras and the points of the power locales.  Lire la suite

    1996 — The power of medicine : "healing" and "tradition" among Dene women in Fort Good Hope, Northwest Territories
    Résumé

    Dene women are leading and directing efforts toward "healing" themselves, their families, and their communities. Employing a modality of montage and storytelling, this thesis explores this enigmatic concept of "healing" among Dene, and its gendered dimensions, in the community of Fort Good Hope, Northwest Territories. This account challenges the limitations of a resistance-hegemony paradigm often used to describe Aboriginal actions as embedded within colonial relations, and endeavours toward a more nuanced analysis which explores Dene "healing" beyond the colonial space. "Healing" is emerging as a vehicle for the assertion and celebration of Dene identity, Dene tradition and "Dene ways". This …  Lire la suite

    This study evaluates the hypothesis that medical reasoning in real clinical situations involves multiple cognitive tasks whose complex interactions are coordinated in an opportunistic manner. A problem-solving architecture originating from research in artificial intelligence, the blackboard model, is proposed as an integrative framework for representing these characteristics of situated medical reasoning and for reconciling different theoretical perspectives about medical reasoning. A naturalistic clinical situation, involving the manipulation of the patient record by an internist while managing a case, provides the empirical data for this in depth qualitative case study. The video recording of the subject's record manipulation behavior allows the …  Lire la suite

    The control of B lymphocyte production in bone marrow is of central importance in maintaining a supply of new B cells for primary humoral immune responses throughout life, while its perturbation may underlie states of immunodeficiency, neoplasia and autoimmunity. Molecules expressed by developing B cells and stromal cells within bone marrow, as well as systemic factors, may all play key roles in regulating proliferation and survival of precursor B cells in bone marrow. Candidate regulatory molecules investigated in the present work include surrogate light chains (SL) of immunoglobulin (Ig) expressed intracellularly by precursor B cells before and during the synthesis …  Lire la suite

    A hypothetical mechanism for the loss of papermaking and printing potential of recycled paper is the adsorption and entrapment of molecules of low surface energy such as oil and soap, on the wood fibers during recycling. A sensitive technique to quantify the retention of contaminants on the pulp is to follow the dynamics of retention of a concentration pulse generated at the entrance (breakthrough curve, BTC) of a packed bed of fibers. Using this technique, we showed that sodium salts of fatty acids undergo ion-exchange with the calcium present in the pulp. Soap prepared by mixing equimolar amounts of sodium …  Lire la suite

    Psychological mindedness refers to a person's ability to perceive relationships among thoughts, feelings, and action with the goal of learning the meanings and causes of his/her experiences and behavior. Psychological mindedness is clinically important because it influences the patient selection for and the efficacy of psychotherapy. Individuals who have difficulty symbolizing and resolving emotional conflict, and verbally expressing their emotions, are considered to lack psychological mindedness and are sometimes labelled "alexithymic." Culture also influences individual styles of emotional expression and the manner and extent to which feelings are labelled as such. Such cultural differences may be interpreted as differences in …  Lire la suite

    A novel process to efficiently produce anhydrous, oxide free MgCl 2 feed to a magnesium electrolysis cell is presented and examined in this thesis. The process involves reducing MgCl2 activity within a fused salt mixture via complexation and reacting any contaminating oxides that are mostly MgO with HCl(g). This process would not be possible nor economical if the MgCl2 activity was not reduced via complexation. This system is modeled here by treating the complexation as decreasing the MgCl2 activity coefficient in a fused salt mixture. The chlorination was modeled thermodynamically using recently published thermodynamic data presented by Thompson et al. …  Lire la suite

    The physics of oil and petroleum evaporation are investigated. Literature on oil spill evaporation shows that most workers use boundary-layer equations adapted from water evaporation work. These equations predict a constant evaporation mass-transfer rate, dependent on scale size and wind speed. Evaporation was studied further by measuring evaporation of commercial oil products. An experimental apparatus for the study of evaporation was developed. Evaporation was determined by weight loss measured on a balance and recorded constantly on a computer. Examination of the data shows that most oil and petroleum products evaporate at a logarithmic rate with respect to time. This is …  Lire la suite

    In this work, I will be looking at the cross-linguistic restrictions on coda position, especially with regard to sonority and place. I propose that these restrictions can be best captured if we acknowledge two types of constraints; those which restrict the licensing ability of codas, as well as those which set out a relationship between a coda and a following onset. I show that in allowing for this distinction, the contrast between the restrictions on word-internal codas and word-final ones falls out straightforwardly. This study is carried out in the framework of Optimality Theory, but the basic claims are expected …  Lire la suite

    1996 — Molecular characterization of dechlorination potential in kraft pulp mill effluent treatment systems
    Résumé

    Many low molecular weight chlorinated organic compounds produced by the pulp and paper industry during kraft bleaching of the wood pulp are toxic. Mass balance studies suggest that mineralization of chlorinated organics is occurring in pulp and paper mill wastewater treatment systems. To understand the nature of dechlorination activity, molecular tools such as oligonucleotide primers and corresponding DNA probes were developed to monitor the presence of microorganisms possessing key genes (dehalogenases) responsible for the degradation of chloroaliphatic organics in kraft pulp mill effluent treatment systems. Oligonucleotide primers designed from the coding sequence of known dehalogenases and a methane monooxygenase gene, …  Lire la suite

    1996 — A critique of the powers and duties of the assembly of the International Civil Aviation Organization (ICAO) /
    Résumé

    It is indeed strange that the Assembly of the International Civil Aviation Organization (ICAO), composed of all the present 183 member States, should have no powers in connection with the principal functions of the Organization (that is, the formulation of Standards and Recommended Practices); nor any over the appointment and creation of the Organization's principal officers and sub-organs. Stranger still is the fact that even the little and insignificant powers that this Assembly might possess can be easily and constitutionally/conventionally "usurped", or interfered with, by the limited 33-member Council of the Organization. Much more puzzling is the fact that this …  Lire la suite
