Esta pesquisa de mestrado se dedica a dialogar com conhecimentos ancestrais da Capoeira Angola, a fim de tramar suas contribuições para o campo da educação escolar. E assim, contribuir ao processo de implementação das leis 10.693/03 e 11.645/08, especialmente ao que se referem aos recursos didáticos que compreendam saberes de matrizes africana, indígena e afro-brasileira. Trata-se dum estudo de algumas imagens literárias da Mãe-Capoeira em verso e prosa, orais e escritas, e em desenho. Utilizando-se de uma linguagem espiral que mescla o vigor da tradição e o rigor da dissertação acadêmica, os materiais da pesquisa entraram em diálogo com a perspectiva mitohermenêutica de uma educação de sensibilidade; com produções orais e escritas sobre as singularidades das cosmovisões africana, ameríndia e afro-brasileira; e com algumas produções, orais e escritas, do feminismo negro. Neste diálogo, flertamos com imagens dos modos matriais afro-ameríndios de fazer-saber e en-sinar num jogo tenso com os modos patriarcais branco-ocidentais da escolarização. Nesse sentido, flertamos com imagens literárias da Mãe-Capoeira e da família-capoeira. E então, com imagens das partilhas iniciáticas e das ligas vitais Capoeira-mestre-discípula/o e pessoa-família extensa. Isto porque desejamos favorecer no prosseguimento da construção de uma noção afro-ameríndia de pessoa-comunal, de conhecimento como força vital, de força-alma-palavra e de educação circular. De modo a tramarmos reinvenções antirracistas, antimachistas e não adultocêntricas nas formas e matérias das práticas escolares e acadêmicas de educação. / This master study is dedicated to dialogue with the ancestral knowledge of Capoeira Angola, in order to plot their contributions to education field. And thus, contribute to the implementation process of law 10.693/03 and 11.645/08, especially as it relates to teaching resources comprising knowledge african, ameríndians and afro-brazilian matrices. It\'s a study of some literary images of Mãe Capoeira in verse and prose, written and oral, and drawing. Using a language that combines the spiral vigour of tradition and rigor of academic dissertation, research materials went into dialogue with the mitohermenêutica perspective of an sensitivity education, with oral and written productions about the african, amerindian and afro-brazilian worldviews singularities; and with some black feminism productions, written and oral. In this dialogue, flirt with afro-amerindian matrials images ways of making-knowledge and lead-up-to-lot in a tense game with the white-western patriarchal modes of schooling. In this sense, we flirt with literary images of the Mãe-Capoeira and family-capoeira. And then, with images of initiation shares and vital alloys Capoeira-master-disciple and person-family-extended. This is because we want to encourage the continuation construction of an afro-amerindian-communal-person notion, knowledge as a vital force, word-soul-force and circular education. In order to ploting anti-racist, antimachists and not adultcentrics reinventions in the forms and materials of school practices and academic education.

Le développement de l’énergie renouvelable loin des zones urbaines demande le transport d'une grande quantité d’énergie sur de longues distances. Le transport d’électricité en courant continu haute tension (HVDC) présente beaucoup d’avantages par rapport à celui en courant alternatif. Dans ce contexte il est nécessaire de développer des convertisseurs de puissance constitués par des composants électroniques très haute tension, 10 à 30 kV. Si les composants en silicium ne peuvent pas atteindre ces objectifs, le carbure de silicium (SiC) se positionne comme un matériau semiconducteur alternatif prometteur. Pour supporter des tensions élevées, une région de "drift", relativement large et peu dopée constitue le cœur du composant de puissance. En pratique l’obtention d’une tension de blocage effective dépend de plusieurs facteurs et surtout de la conception d'une terminaison de jonction adaptée. Cette thèse présente une méthode pour améliorer la tenue en tension des composants en SiC basée sur l’utilisation des terminaisons de jonctions : Deep Trench Termination. Cette méthode utilise une tranchée gravée profonde en périphérie du composant, remplie avec un matériau diélectrique pour supporter l'étalement des lignes équipotentielles. La conception de la diode avec cette terminaison a été faite par simulation TCAD, avec deux niveaux de tension 3 et 20 kV. Les travaux ont pris en compte les caractéristiques du matériau, les charges à l’interface de la tranchée et les limites technologiques pour la fabrication. Ce travail a abouti sur la fabrication de démonstrateurs et leur caractérisation pour valider notre conception. Lors de la réalisation de ces structures, la gravure plasma du SiC a été optimisée dans un bâti ICP de manière à obtenir une vitesse de gravure élevée et en conservant une qualité électronique de l'état des surfaces gravées. Cette qualité est confirmée par les résultats de caractérisation obtenus avec des tenues en tension proches de celle idéale. / The development of renewable energy away from urban areas requires the transmission of a large amount of energy over long distances. High Voltage Direct Current (HVDC) power transmission has many advantages over AC power transmission. In this context, it is necessary to develop power converters based on high voltage power electronic components, 10 to 30 kV. If silicon components cannot achieve these objectives, silicon carbide (SiC) is positioned as a promising alternative semiconductor material. To support high voltages, a drift region, relatively wide and lightly doped is the heart of the power component. In practice obtaining an effective blocking voltage depends on several factors and especially the design of a suitable junction termination. This thesis presents a method to improve the voltage withstand of SiC components based on the use of junction terminations: Deep Trench Termination. This method uses a trench deep etching around the periphery of the component, filled with a dielectric material to support the spreading of the equipotential lines. The design of the diode with this termination was done by TCAD simulation, with two voltage levels 3 and 20 kV. The work took into account the characteristics of the material, the interface charge of the trench and the technological limits for the fabrication. This work resulted in the fabrication of demonstrators and their characterization to validate the design. During the production of these structures, plasma etching of SiC has been optimized in an ICP reactor so as to obtain a high etching rate and maintaining an electronic quality of the state of etched surfaces. This quality is confirmed by the results of characterization obtained with blocking voltage close to the ideal one.
