abstract: A new arrangement of the Concerto for Two Horns in E-flat Major, Hob. VIId/6, attributed by some to Franz Joseph Haydn, is presented here. The arrangement reduces the orchestral portion to ten wind instruments, specifically a double wind quintet, to facilitate performance of the work. A full score and a complete set of parts are included. In support of this new arrangement, a discussion of the early treatment of horns in pairs and the subsequent development of the double horn concerto in the eighteenth century provides historical context for the Concerto for Two Horns in E-flat major. A summary of the controversy concerning the identity of the composer of this concerto is followed by a description of the content and structure of each of its three movements. Some comments on the procedures of the arrangement complete the background information. / Dissertation/Thesis / D.M.A. Music 2011

On utilise la théorie de Floquet-Lin pour des systèmes différentiels linéaires quasi- périodiques pour établir des résultats d'existence et d'unicité et de dépendance continue des systèmes différentiels non linéaires quasi-périodiques. Et dans un second temps on établit un résultat de réductibilité d'un système différentiel linéaire presque-périodique en un système différentiel linéaire triangulaire supérieur avec conservation du nombre des solutions presque-périodiques indépendantes. Ensuite, un résultat d’existence et d’unicité et de dépendance continue des systèmes différentiels non linéaires presque-périodiques par rapport au terme du contrôle. / We use a Floquet theory for quasi-periodic linear ordinary differential equations due to Zhensheng Lin to obtain results, of existence, unicity, continuous and differentiable dependence, on the quasi-periodic solutions of quasi-periodic nonlinear ordinary differential equations. in a second time we establish the reducibility of linear systems of almost periodic differential equations into upper triangular systems of a. p. differential equations. This is done while the number of independent a. p. solutions is conserved. We prove existence and uniqueness of a. p. solutions of a nonlinear system with an a. p. linear part. Also we prove the continuous dependence of a. p. solutions of a nonlinear system with respect to an a. p. control term.

Cette thèse s’intéresse au tissage et au préformage de renforts fibreux à base de fibres de lin. Avant d’être utilisés, ces fibres sont disposées en faisceaux de faible longueur (~ 30 mm en moyenne) et ont besoin d’être assemblées pour constituer un renfort linéaire continu. L’utilisation de rubans ou de rovings sans torsion est recommandée pour des applications composites. Dans un premier temps, cette étude se concentre sur l’élaboration et l’utilisation de rovings traités par un agent d’encollage et sans torsion ainsi que sur l’influence des paramètres du procédé de tissage sur les propriétés mécaniques et les caractéristiques textiles des renforts tissés. Pour éviter l’endommagement de ces rovings durant le tissage, des solutions sont proposées. Dans un second temps cette thèse s’intéresse à la mise en forme de ces renforts sur une géométrie complexe. Ce travail se concentre alors sur l’étape de préformage du procédé RTM. Une approche expérimentale est abordée pour identifier et quantifier les défauts apparaissant durant l’emboutissage sur une géométrie complexe comme le tétraèdre. Cette analyse se concentre en particulier sur le défaut de bouclage causé par un fléchissement des mèches. Des solutions comme l’optimisation de l’architecture des renforts sont observées pour obtenir cette géométrie complexe sans défaut avec des renforts à base de fibres de lin. La forme, le positionnement ainsi que la pression appliquée sur les serre-flans maintenant le renfort au cours du passage du poinçon influent également sur la génération des défauts. L’optimisation du procédé d’emboutissage pour empêcher l’apparition de boucles sur les préformes conclut ce travail. / This work focuses on the weaving and forming of flax based reinforcements. Before being woven, naturalfibres on the form of finite length bundles (~ 30 mm in average for flax) need to be assembled together in a1D continuous product. The use of roving or slivers without twist is rather recommended for compositeapplications. In a first part, this study focuses on the manufacturing and the use of untwisted rovings treatedwith a bonding agent as well as on the weaving process parameters that may influence the mechanicalproperties and the textile characteristics of the woven fabric. Solutions to prevent roving defects duringweaving are proposed. In a second part, this study investigates the ability to develop composite parts with complex geometrieswithout defect. It focuses on the first step of RTM process which consists in forming dry fibrousreinforcements. An experimental approach is used to identify and quantify the defects. The buckling defectcaused by the bending of tows during the preforming step is particularly investigated. Solutions to realize acomplex shape such as a tetrahedron without any defect from flax based woven reinforcements areproposed. With optimized reinforcement architecture, buckling can be prevented. Another solutionconsisting in optimising the process parameters such as the blank holder geometry or the blank holderpressure to prevent the appearance of buckles from commercial fabrics was also investigated with success.

Lin chose certain points along the Columbia River to commemorate the bicentennial of the Corps of Discovery, the Lewis and Clark Expedition. I will focus on the third completed site, Bird Blind, located at the Sandy River Delta in Troutdale, Oregon. This artwork is a functional piece for viewing the surrounding wildlife in addition to a textually informative work referencing the diaries of Lewis and Clark and includes the current species status report published by the Sierra Club on the animals observed by Lewis and Clark. This thesis examines the accessibility of the artwork to the wide variety of audiences and its success as a point of dialogue for its specific site. / Committee in Charge: Dr. Kate Mondloch; Dr. Leland Roth; Prof. Kenneth Helphand

Due to this fact, different implementations for the LK were proposed in literature and this heuristic is also used as part of various meta-heuristic algorithms. LK has been used in the context of the multi-objective TSP (MTSP) as originally proposed by its authors, i.e., with a single objective focus. This study investigates variants of the LK heuristic in the multi-objective context. We investigate the potential of LK extensions combined with other metaheuristic techniques. Results of a computational experimental are reported for MTSP instances with 2, 3 and 4 objectives.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / O cultivo de Anacardium occidentale Lin, mais conhecido popularmente como cajueiro, à uma das atividades agropecuÃrias mais importantes do Nordeste brasileiro. à utilizada na medicina tradicional para fins terapÃuticos, incluindo atividade antimicrobiana. O objetivo do presente trabalho foi avaliar o potencial antimicrobiano da infusÃo de folhas de cajueiro em diferentes horÃrios de coleta frente à bactÃria Streptococcus mutans e analisar o potencial tÃxico e citotÃxico das infusÃes nas concentraÃÃes utilizadas. A ConcentraÃÃo InibitÃria MÃnima (CIM) foi determinada nos horÃrios de 7, 9, 11, 13, 15, 17 e 19h utilizando a cepa de S. mutans UA159. TambÃm foi determinada a ConcentraÃÃo Bactericida MÃnima (CBM) e foram realizados testes de toxicidade das infusÃes em Artemia salina Leach e citotoxicidade na presenÃa da enzima LDH em neutrÃfilo humano. Os resultados dos ensaios antimicrobianos mostraram que as infusÃes de folhas de cajueiro podem estimular, inibir ou nÃo ter efeito sobre o crescimento bacteriano, conforme a hora de coleta e a concentraÃÃo. Os valores das CIMs foram de 250 Âg.mL-1 (7h), 125 Âg.mL-1 (9-15h) e 62,5 Âg.mL-1 (17 e 19h). Ocorreu estÃmulo no crescimento bacteriano nas concentraÃÃes de 15,62 Âg.mL-1 (9-19h), 31,25 Âg mL-1 .(15h) e 62,50 Âg.mL-1 (15h). A infusÃo coletada Ãs 7h nÃo apresentou nenhuma concentraÃÃo de estÃmulo. Nos testes de ConcentraÃÃo Bactericida MÃnima (CBM) as infusÃes foram consideradas como bacteriostÃtica. Os testes de toxicidade em Artemia salina resultaram em valores para a concentraÃÃo letal mÃdia (CL50) de 266,15; 285,48 e 345,15 nos horÃrios de coleta de 11, 17 e 19h, respectivamente. Assim, para esses horÃrios de coleta as infusÃes foram consideradas atÃxicas nos seus valores de CIMs (125 e 62,5Âg.mL-1 ). Os testes de citotoxicidade mostraram que as infusÃes nÃo sÃo tÃxicas nas concentraÃÃes de 1, 10, 100 e 200Âg.mL-1. / The cultivation of Anacardium occidentale Lin, more known as cashew tree, is one of the most important agriculture and stock-breeding activities in the northeast of Brazil. It is used in traditional medicine with therapeutic purposes, including antigerm activitiy. The objective of this work is to check the antigerm potential by infusing the leaves of the cashew tree in different hours of collection before the bacterium Streptococcus mutans. Its objective also includes the analysis of the toxical and cytotoxical potential of these infusions in used concentrations. The Minimum Inhibitory Concentration (MIC) was determined in the time- tables 7,9,11,13,15,17 and 19H using the cepa of S.mutans UA159. It was also determined the Minimum Bactericidal Concentration (MBC), when tests of toxicity of infusions were done in Artemia salina Leach and cytotoxicity in the presence of LDH enzyme in human neutrophil. The results of the antigerm samples showed that the infusions of the leaves of the cashew tree may stimulate, inhibit or not present effects on the bacterium growth, according to the time of collection and concentration. The values of the MIC (Minimum Inhibitory Con- centration) were 250 Âg.mL-1 (7h), 125 Âg. mL-1 (9-15h) e 62,5 Âg. mL-1 (17 e 19h). Some stimulus occured in the bacterium growth in the following concentrations: 15,62 Âg. mL-1 (9- 19h), 31,25 Âg mL-1 .(15h) e 62,50 Âg. mL-1 (15h). The collected infusion at 7 A.M. did not present any stimulus concentration. In the tests of Minimum Bactericidal Concentration (MBC), the infusions were considered bacteriostatic. The tests of toxicity in Artemia salina resulted in values for the average lethal concentration (CL50) of 266,15; 285,48 and 345,15 in the collection times of 11, 17 and 19h, respectively. Therefore, for the hours of colletion the infusions were considered nontoxical in their values of Minimum Inhibitory Concentration (125 e 62,5Âg.mL-1 ). The tests of cytotoxicity showed that the infusions were not toxical in the concentrations of 1, 10, 100 e 200Âg. mL-1.

De nos jours, il est nécessaire de trouver des substituts aux produits dérivés du pétrole car ces derniers ne sont pas renouvelables. C’est donc dans ce but que nous avons envisagé d’élaborer des matériaux constitués principalement d’huile de lin. Ces matériaux ont été élaborés en trois étapes au moyen d’un procédé propre et simple. La première étape est une polymérisation thermique (standolisation), suivie ou précédée d’une étape de modification chimique, tout d’abord par l’anhydride maléique puis par le 2-hydroxyéthyl-méthacrylate (HEMA) qui permet d’introduire des groupements photoréticulables au sein des chaînes de triglycérides. La dernière étape consiste à photopolymériser les huiles modifiées. Nous avons fait varier les taux de standolisation et de modification, puis nous avons déterminé les propriétés physico-chimiques des différents matériaux. La température de transition mécanique de ces matériaux est toujours inférieure à -5 °C et leur flexibilité est d’autant plus importante que le taux de modification est faible. La stabilité thermique ainsi que la biodégradabilité des matériaux ont aussi été étudiées. / The use of renewable sources such as vegetable oils in the elaboration of various industrial materials has been recently revitalized because of the environmental concerns. This is in this context that the elaboration of new materials mainly based on linseed oil was envisaged. These new materials were elaborated in three stages, by means of an easy and clear process. The first stage consisted in a thermal or stand reaction, followed or preceded by a chemical modification stage by maleic anhydride. Then, the 2-hydroxyethylmethacrylate (HEMA) was grafted on the anhydride functions to introduce photopolymerizable groups. In the last stage, the photopolymerization of the modified oil was carried out. The influence of stand and modification rates on the ultimate UV-cured materials properties was characterized. All these materials exhibited a mechanic transition temperature lower than –5 °C and their flexibility was all the higher than the modification rate is low. Thermal stability as well as biodegradation of these materials were also determined.

In Spagna, nel periodo storico compreso tra i secoli XVIII e XIX, il profondo desiderio di progresso diede vita a un momento di grande dinamicità per i settori tecnico-scientifici. L’entrata di nuove conoscenze provenienti da paesi esteri, unita alle scoperte della chimica e della meccanizzazione, influenzò i principali settori produttivi che, in quel momento, erano di natura artigianale. In questo contesto si assiste alla lenta ma inesorabile transizione dalle produzioni artigianali delle corporazioni all’industria. Il presente lavoro di ricerca osserva le dinamiche lessicali di questo mutamento, focalizzandosi su un dominio specifico: arti e mestieri della pelle. Lo studio, attraverso un approccio metodologico che spazia tra aree disciplinari linguistiche come la lessicologia e la lessicografia ed extra-linguistiche, si pone il raggiungimento di tre obiettivi. In primo luogo, viene per la prima volta censito ed analizzato il lessico delle arti e mestieri della pelle, osservato nel cruciale passaggio da arte a industria. In secondo luogo, viene osservata la capacità di adattamento del lessico alle nuove esigenze espressive mediante l’analisi dei meccanismi di creazione lessicale. Da ultimo, lo studio si propone di verificare l’esistenza di un legame che unisce lo sviluppo di una lingua alle dinamiche che interessano il contesto socio-culturale. / The Spanish society, between the eighteenth and nineteenth centuries, felt a need for progress which leads to an important period of development in technical and scientific fields. The circulation of concepts and knowledges coming from foreign countries and the impressive progress of chemistry and mechanics influenced the most important manufactures, characterized by a traditional craftsmanship. This is the context of a slow but inexorable transition to the industrial production. The aim of the present work is to observe the lexical dynamics analysing a specific domain: the art of tanning leather. The research, by an interdisciplinary methodological approach, achieves three objectives: collecting and analysing the Spanish leather tanning lexicon in its crucial passage from local craft to industry, observing the lexicon self-adaptation capability to the new communicative needs by analysing the lexical creation mechanisms and verify the existence of a link between the evolution of a language and the dynamics that concern the socio-cultural context.
