Engendered Conversations: Gender Subversion Through Fictional Dialogue in Lawrence, Hemingway and Forster

This dissertation examines gendered fictional dialogue in popular works by D.H. Lawrence, Ernest Hemingway and E.M. Forster, including Howards End (1910), The Sun Also Rises (1926) and Lady Chatterley’s Lover (1928). I apply Judith Halberstam’s notion of female masculinity to direct speech, to explore how speech traits inform modernist literary aesthetics. My introduction frames this discussion in sociolinguistics, Judith Butler’s theory of performativity, M.M. Bakhtin’s discourse theory, and gender studies. It provides an opportunity to establish experimental dialogue techniques, and the manipulation of gendered talk, in transgressive texts including James Joyce’s Ulysses (1922), Virginia Woolf’s Orlando (1928) and Radcyffe Hall’s The Well of Loneliness (1928). The first chapter discusses taboos and dialect in D.H. Lawrence’s fictional dialogue. The second chapter establishes gender subversion as a crucial element in Ernest Hemingway’s dialogue style. The third chapter contrasts Forster’s latently gendered speech with his techniques of dialect emphasis and dialect suppression. Finally, my conclusion discusses gender identity in the poetry of Dorothy Parker and Baroness Elsa von Freytag Loringhoven, and the temporality of gender in “Time Passes” from Virginia Woolf’s To the Lighthouse (1927). New Woman characters like Lady Brett Ashley typified a crucial moment in women’s liberation. They not only subverted stereotypes of womanhood through their dress or sexual freedom, they also adopted/adapted masculine idiom to shock, to rebel against and challenge male dominance. Different speech acts incited fashionable slang, became a political protest symbol or inspired psychoanalytic theory. The intriguing functions of women’s masculine speech in early twentieth century fiction establishes the need to examine additional connections between gender and talk in literary studies.

Le choix du tout-à-l'automobile à Montréal (1953-1967) : un contexte propice à l’aménagement de l'échangeur Turcot

En l’espace d’une décennie, Montréal s’est durablement transformée. Du milieu des années 1950, où elle représente une ville développée certes, mais dépourvue d'autoroutes, à 1967, année de l’Exposition universelle, la métropole du Québec confirme son choix du tout-à-l’automobile. Le développement autoroutier qu’elle réalise à cette époque doit alors être en mesure de répondre aux besoins de la société à court comme à long terme. Ce réseau perdure toujours de nos jours. Nous souhaitons décomposer la trame de cette période mouvementée afin de comprendre comment Montréal a pu adopter cette orientation aussi rapidement. Il est question d’aborder les éléments ayant permis de centraliser le thème de la circulation à Montréal. La réponse des autorités et la volonté de planifier la ville à long terme nous conduisent ensuite à une réalisation accélérée d’un réseau autoroutier métropolitain d’envergure dont l’échangeur Turcot représente l’aboutissement en 1967. Cette étude permet de mieux examiner l’histoire de ce projet autoroutier majeur qui a constitué un des symboles forts de la modernisation de Montréal et du Québec. L’échangeur Turcot construit dans les années 1960 est le fruit d’une conjoncture particulière, correspondant à des besoins et des attentes tout autre que ceux qui prévalent actuellement. Nous concluons ainsi en nous questionnant sur la construction actuelle du nouvel échangeur Turcot, et en affirmant qu’elle ne correspond peut-être pas aux besoins d’une métropole du XXIe siècle.

Conception et évaluation d’un nouveau système de transfection ciblée, basé sur l’utilisation du système E/Kcoil

Actuellement le polyéthylènimine (PEI) est l’agent de transfection transitoire le plus utilisé par l’industrie pharmaceutique pour la production de protéines recombinantes à grande échelle par les cellules de mammifères. Il permet la condensation de l’ADN plasmidique (ADNp) en formant spontanément des nanoparticules positives appelées polyplexes, lui procurant la possibilité de s’attacher sur la membrane cellulaire afin d’être internalisé, ainsi qu’une protection face aux nucléases intracellulaires. Cependant, alors que les polyplexes s’attachent sur la quasi-totalité des cellules seulement 5 à 10 % de l’ADNp internalisé atteint leur noyau, ce qui indique que la majorité des polyplexes ne participent pas à l’expression du transgène. Ceci contraste avec l’efficacité des vecteurs viraux où une seule particule virale par cellule peut être suffisante. Les virus ont évolués afin d’exploiter les voies d’internalisation et de routage cellulaire pour exprimer efficacement leur matériel génétique. Nous avons donc supposé que l’exploitation des voies d’internalisation et de routage cellulaire d’un récepteur pourrait, de façon similaire à plusieurs virus, permettre d’optimiser le processus de transfection en réduisant les quantités d’ADNp et d’agent de transfection nécessaires. Une alternative au PEI pour transfecter les cellules de mammifèreest l’utilisation de protéines possédant un domaine de liaison à l’ADNp. Toutefois, leur utilisation reste marginale à cause de la grande quantité requise pour atteindre l’expression du transgène. Dans cette étude, nous avons utilisé le système E/Kcoil afin de cibler un récepteur membranaire dans le but de délivrer l’ADNp dans des cellules de mammifères. Le Ecoil et le Kcoil sont des heptapeptides répétés qui peuvent interagir ensemble avec une grande affinité et spécificité afin de former des structures coiled-coil. Nous avons fusionné le Ecoil avec des protéines capables d’interagir avec l’ADNp et le Kcoil avec un récepteur membranaire que nous avons surexprimé dans les cellules HEK293 de manière stable. Nous avons découvert que la réduction de la sulfatation de la surface cellulaire permettait l’attachement ciblé sur les cellules par l’intermédiaire du système E/Kcoil. Nous démontrons dans cette étude comment utiliser le système E/Kcoil et une protéine interagissant avec l’ADNp pour délivrer un transgène de manière ciblée. Cette nouvelle méthode de transfection permet de réduire les quantités de protéines nécessaires pour l’expression du transgène.

Synthèse et étude de nouvelles molécules potentiellement polymérisables pour la fabrication de matériaux électroluminescents : analogues du 1,3,5 benzènetripyrrole, méthyle 3,5-bipyrrolebenzoate et 6,12-diméthyle-1,5-dipyrrolediazocane

Pyrroles are found in various natural products and in the chemical composition of certain drugs because of their interesting biological properties. Lipitor, Tolmetin and Amtolmetin are examples of drugs with 1,2,5-substituted pyrroles in their composition, in which biological activities have been certified. Moreover, pyrroles are used as precursors of semiconductor polymers, oligomers and dendrimers useful for the synthesis of electroluminescent materials used in devices, such as organic light-emitting diodes, field-effect transistors, solar and organic photovoltaic cells. We are interested in conjugated polymers based on pyrrole due to their optical properties, electrochemical and the conductivity produced by electron delocalization along their carbon chains. The overall objective of the work presented in this thesis is the synthesis of new molecules based on pyrrole for studying their electronic and electrochemical properties as well for the synthesis of conjugated polymers. Initially, we performed the synthesis of 1,3,5-tri-(1-alkyl-5-methylpyrrol-2-yl)benzenes, which may serve as precursors for the synthesis of conjugated dendrimers. Their synthesis was made in three steps starting from trimethyl 1,3,5-benzene-tricarboxylate which was converted to 1,3,5-tri-(pent-4-enoyl)benzene using vinylmagnesium bromide in a Grignard reaction catalyzed by copper cyanide. The olefins of 1,3,5-tri-(pent-4-enoyl)benzene were oxidized to produce 1,3,5-tri-(4-oxopentanoyl)benzene using a modified protocol of the Tsuji-Wacker reaction. Subsequent, Paal-Knorr condensation reactions on 1,3,5-tri-(4-oxopentanoyl)benzene with different amines were used to synthesize 1,3,5-tri-(1-alkyl-5-methylpyrrol-2-yl)benzenes with different N-substituents in yields between 44 and 60%. Incomplete reaction of vinylmagnesium bromide with trimethyl 1,3,5-benzenetricarboxylate gave the methyl-3,5-di(pent-4-enoyl)benzoate, which was converted to methyl-3,5-dipyrrolylbenzoate following the reaction of Tsuji- Wacker and Paal-Knorr with yields between 30 and 60%. The photochemical and electrochemical properties of the 1,3,5-tri-(1-alkyl-5-methylpyrrol-2-yl)benzenes and methyl-3,5-dipyrrolylbenzoates were studied in collaboration with the research group of professor William Skene. The results have shown that both types of pyrrole have potential for the synthesis of conjugated polymers and dendrimers used in the manufacture of electroluminescent materials. Following these encouraging results, we performed the synthesis of 6,12-dimethyl-1,5-dipyrrolediazocane. Methyl N-(Boc)-β-alaninate was converted to its corresponding homoallylic ketone, which was oxidized to N-(Boc)aminoheptan-3,6-dione. The Paal-Knorr condensation between N-(Boc)aminoheptan-3,6-dione and aminoheptan-3,6-dione hydrochloride gave 6,12-dimethyl-1,5-dipyrrolediazocane in 17% yield. In sum, we have synthesized and characterized seven new molecules, six of them having photochemical and electrochemical properties interesting for the synthesis of conjugated polymers and dendrimers. The latter offering potential as precursor for the conception of compounds of therapeutic interest.

La tagatose-1,6-bisphosphate aldolase et la fructose-1,6-bisphosphate aldolase de classe I : mécanisme et stéréospécificité

La tagatose-1,6-biphosphate aldolase de Streptococcus pyogenes est une aldolase qui fait preuve d'un remarquable manque de spécificité vis à vis de ses substrats. En effet, elle catalyse le clivage réversible du tagatose-1,6-bisphosphate (TBP), mais également du fructose-1,6-bisphosphate (FBP), du sorbose-1,6-bisphosphate et du psicose-1,6-bisphosphate, quatre stéréoisomères, en dihydroxyacétone phosphate (DHAP) et en glycéraldéhyde-3-phosphate (G3P). Aldolase de classe I, qui donc catalyse sa réaction en formant un intermédiaire covalent obligatoire, ou base de Schiff, avec son susbtrat, la TBP aldolase de S. pyogenes partage 14 % d’identité avec l’enzyme modèle de cette famille, la FBP aldolase de muscle de mammifère. Bien que le mécanime catalytique de la FBP aldolase des mammifères ait été examiné en détails et qu’il soit approprié d’en tirer des renseignements quant à celui de la TBP aldolase, le manque singulier de stéréospécificité de cette dernière tant dans le sens du clivage que celui de la condensation n’est toujours pas éclairci. Afin de mettre à jour les caractéristiques du mécanisme enzymatique, une étude structurale de la TBP aldolase de S. pyogenes, un pathogène humain extrêmement versatile, a été entreprise. Elle a permis la résolution des structures de l’enzyme native et mutée, en complexe avec des subtrats et des inhibiteurs compétitifs, à des résolutions comprises entre 1.8 Å et 2.5 Å. Le trempage des cristaux de TBP aldolase native et mutante dans une solution saturante de FBP ou TBP a en outre permis de piéger un authentique intermédiaire covalent lié à la Lys205, la lysine catalytique. La determination des profils pH de la TBP aldolase native et mutée, entreprise afin d'évaluer l’influence du pH sur la réaction de clivage du FBP et TBP et ìdentifier le(s) résidu(s) impliqué(s), en conjonction avec les données structurales apportées par la cristallographie, ont permis d’identifier sans équivoque Glu163 comme résidu responsable du clivage. En effet, le mode de liaison sensiblement différent des ligands utilisés selon la stéréochimie en leur C3 et C4 permet à Glu163, équivalent à Glu187 dans la FBP aldolase de classe I, d’abstraire le proton sur l’hydroxyle du C4 et ainsi d’amorcer le clivage du lien C3-C4. L’étude du mécanimse inverse, celui de la condensation, grâce par exemple à la structure de l’enzyme native en complexe avec ses substrats à trois carbones le DHAP et le G3P, a en outre permis d’identifier un isomérisme du substrat G3P comme possible cause de la synthèse des isomères en C4 par cette enzyme. Ce résultat, ainsi que la decouverte d’un possible isomérisme cis-trans autour du lien C2-C3 de la base de Schiff formée avec le DHAP, identifié précedemment, permet de cerner presque complètement les particularités du mécanisme de cette enzyme et d’expliquer comment elle est capable de synthétiser les quatres stéréoisomères 3(S/R), 4(S/R). De plus, la résolution de ces structures a permis de mettre en évidence trois régions très mobiles de la protéine, ce qui pourrait être relié au rôle postulé de son isozyme chez S. pyogenes dans la régulation de l’expression génétique et de la virulence de la bactérie. Enfin, la résolution de la structure du mutant Lys229→Met de la FBP aldolase de muscle en complexe avec la forme cyclique du FBP, de même que des études cristallographiques sur le mutant équivalent Lys205→Met de la TBP aldolase de S. pyogenes et des expériences de calorimétrie ont permis d’identifier deux résidus particuliers, Ala31 et Asp33 chez la FBP aldolase, comme possible cause de la discrimination de cette enzyme contre les substrats 3(R) et 4(S), et ce par encombrement stérique des substrats cycliques. La cristallographie par rayons X et la cinétique enzymatique ont ainsi permis d'avancer dans l'élucidation du mécanisme et des propriétés structurales de cette enzyme aux caractéristiques particulières.

Cyclic voltammetric studies on these dibezoyalkenes to compare their redox behaviour with that of the cis and trans isomers of dibenzoyl-ethylene, dibenzoylstilbene. These results should provide some information about their reactivity, and to assess and exploit the potential of these systems as quinonemethides. This study conclude that a number of new dibenzolalkene-type systems have been synthesized by the Claisen-Schmidt condensation of 1,2-diketones such as phenanthequinone and acenaphthenequinone with methyl ketones. Some of these compounds have been shown to undergo interesting photochemical transformations. Based on the results it is conclude that phenanthjrenone-9-ylidene ketones are excellent Michael acceptors. Methanol adds to these to yield the corresponding furanols. These furanols are unstable and are slowly converted to phenanthro-2 (3H)-furanones.

Fuzzy Absolutes and Related Topics

The study on the fuzzy absolutes and related topics. The different kinds of extensions especially compactification formed a major area of study in topology. Perfect continuous mappings always preserve certain topological properties. The concept of Fuzzy sets introduced by the American Cyberneticist L. A Zadeh started a revolution in every branch of knowledge and in particular in every branch of mathematics. Fuzziness is a kind of uncertainty and uncertainty of a symbol lies in the lack of well-defined boundaries of the set of objects to which this symbol belongs. Introduce an s-continuous mapping from a topological space to a fuzzy topological space and prove that the image of an H-closed space under an s-continuous mapping is f-H closed. Here also proved that the arbitrary product fi and sum of  fi of the s-continuous maps fi are also s-continuous. The original motivation behind the study of absolutes was the problem of characterizing the projective objects in the category of compact spaces and continuous functions.

New oligomer-bound antioxidants for improved flex crack resistance and ozone resistance

New oligomer-bound antioxidants have been prepared by condensation reaction. The efficiency and permanence of these oligomer- bound paraphenylene diamines as antioxidants has been compared with conventional amine type antioxidants in NR, SBR, IIR and NBR and in elastomer blends like NR/BR and NR/SBR. The oligomer-bound antioxidants are found to impart improved ozone, flex resistance and mechanical properties to the vulcanizates of NR, SBR, IIR and NBR and to blends of NR/BR and NR/ SBR in comparison with those containing conventional antioxidants.
