Le photovoltaïque nécessite de nouveaux matériaux pour diminuer ces coûts et améliorer les rendements. Ces travaux de thèse ont concerné le développement de nouvelles phases d'oxyde de titane pour l'électronique transparente et la conversion de photon appliquée au PV silicium. L'ablation laser pulsé est une méthode de croissance particulièrement adaptée pour la prospection de matériaux aux propriétés innovantes. Le contrôle des phases anatase, rutile et d'une phase de composition TiO1.45 épitaxié en fonction de la pression partielle d'oxygène a permis de réaliser des films aux propriétés électriques, optiques innovantes. Un film biphasé anatase/rutile dopé niobium (TNO1.80) présente ainsi une transition métal-semi-conducteur aux alentours de 68K. Par ailleurs, le film de composition TiO1.45 épitaxié s'est révélé être un oxyde transparent conducteur de type p. La découverte de ce nouveau p-TCOs a été valorisée et validée par l'élaboration d'une homojonction p - n transparente. Les matrices d'oxyde de titane rutile et anatase ont également été utilisées pour accueillir des ions terres rares Ln3+ afin de convertir les photons ultra-violet du spectre solaire incident vers le proche infrarouge (800 > λ > 1100 nm). Le transfert d'énergie des matrices TiO2 vers les dopants Ln3+ a été étudié en fonction de la structure, de la quantité de dopant ainsi que la qualité de la microstructure des films dopés Ln3+ (Ln3+=Pr3+,Tm3+,Eu3+,Yb3+,Nd3+). / New materials are needed to decrease cost and improve photovoltaic cell performance. These thesis works are focused on the development of new titanium oxide phases for transparent electronic and photon conversion applied to silicon solar cell. Pulsed laser deposition is an adapted growth method for the prospection of materials with innovating properties. The control of epitaxial growth of anatase, rutile and a phase with a composition TiO1.45 in function of oxygen partial pressure allowed us to realize films with innovating electrical and optical properties. A two phase anatase/rutile film doped niobium (TNO1.80) have shown a metal-semiconductor transition about 68 K. Moreover, transparent TiO1.45 epitaxial thin film has displayed a p-type semiconduction behaviour which has been confirmed by the elaboration of a transparent p - n homojunction. Rutile and anatase titanium oxide matrix were also used to host rare earths ions in order to convert ultraviolet to near infra-red photon (800 > λ > 1100 nm). TiO2 matrix to dopant transfer has been studied in function of crystal structure, doping content and the quality of microstructure of films doped Ln3+(Ln3+=Pr3+,Tm3+,Eu3+,Yb3+,Nd3+).

O principal objetivo foi buscar uma nova caracterização dos movimentos utilizados na regência por meio da terminologia anatômica. Os resultados foram conseguidos por uma análise comparativa dos movimentos sugeridos pelos livros e tratados de regência com os movimentos corporais genéricos dados pela Cinesiologia. O intuito deste trabalho é fornecer subsídios para a compreensão do funcionamento do gesto na profissão de regente e, posteriormente, avaliar as condições físicas a que estes indivíduos estão submetidos / Abstract: This dissertation presents a kinesiological view about the descriptions of conductor¿s posture and gesture present in related text books. The main purpose was to search a new characterization of the movements used in conducting using the anatomical terminology. The results were achieved by a comparative analysis of the movements suggested in the conducting books and treatises and the generic body movements described by the Kinesiology. The aim of this work is to provide aids to understand the acting of the gesture in the conductor¿s profession and, then, evaluate the physical conditions to which these individuals are subjected / Mestrado / Praticas Interpretativas / Mestre em Música

Psalm settings by German Baroque composers are comprised of meaningful texts illuminated by expressive music and have much to offer today’s choir. The composers of these settings were inspired by the Old Testament psalm texts and wrote choral works that incorporated both historical techniques adapted from types of psalmody and the expressive techniques of their day. Despite the significance of psalm settings, no detailed study exists on this music as a body of work. Additionally, Baroque music provides challenges to the conductor regarding performance practice choices. Both of these problems are addressed in this study. First, I establish a lineage of compositional development from Medieval chanted psalms to Baroque psalm settings and analyze the techniques composers used to express the text in specific examples. Then, I use the insights gleaned to make performance practice recommendations for each piece. By drawing on primary sources by Michael Praetorius (ca. 1571-1621) and Heinrich Schütz (1585-1672) and secondary sources by contemporary scholars Dennis Schrock, Helmuth Rilling, and Robert Donington, I provide an overview of German Baroque performance practices that includes instrumentation, tempo, dynamics, articulation, and ornamentation. Special emphasis is given to performance principles that are applicable to the psalm settings explored in subsequent chapters. I also draw on dissertations, books, and articles by Baroque scholars to provide highlights of the composers’ careers and details about the pieces studied. The six pieces included in this disquisition are “Wie lieblich sind deine Wohnungen,” SWV 29 from Psalmen Davids (1619) by Heinrich Schütz (1585-1672), Alleluja! Lobet den Herrn in seinem Heiligtum (1620) by Johann Hermann Schein (1586-1630), “Schaffe in mir Gott ein reines Herz” from Fest- und Zeit-Andachten (1671) by Andreas Hammerschmidt (1611-1675), Der Herr ist mit mir, BuxWV 15 (ca. 1687) by Dieterich Buxtehude (ca. 1637-1707), Gott, sei mir gnädig (1705) by Johann Kuhnau (1660-1722), and Lobet den Herrn, alle Heiden (n.d.), BWV 230 by Johann Sebastian Bach (1685-1750).
