The objective of this study was to: (1) model the course of the lingual nerve (LN) in the third molar region using digitized data and (2) investigate landmarks to aid in predicting the position of LN. A MicroScribe 3-DX digitizer and Autodesk® Maya® 8.5 were used to create 3-D in-situ models of LN for seven human cadaveric specimens. Regression analysis demonstrated that an anteriorly positioned lingula is directly proportional to the vertical distance of the LN relative to the alveolar crest (p < 0.05). A superiorly positioned mylohyoid ridge was also directly proportional to the vertical distance of the LN relative to the alveolar crest (p < 0.05). The LN is positioned closer to the alveolar crest in specimens where the mylohyoid ridge is positioned superiorly (p = 0.001). This study demonstrated a novel way of quantifying the relative position of the LN using 3-D computer modeling.

Les marges transformantes, formées par le coulissage des plaques lors des premières étapes de l’ouverture océanique, ont été peu étudiées relativement aux marges divergentes. La marge de Côte d’Ivoire-Ghana fait figure d’exemple-type, et l’absence d’inventaire exhaustif ainsi que le peu d’étude de marges transformantes conjuguées entraîne une méconnaissance de la véritable diversité de ce type de marge. Deux approches ont été abordées dans ce mémoire. La première a consisté à les inventorier dans le monde à partir d’une méthodologie simple. Elles ont ensuite été comparées (physiographie et structure). La deuxième s’est concentrée sur l’étude tectono-sédimentaire des marges transformantes conjuguées des plateaux de Demerara et de Guinée. L’inventaire des marges transformantes a montré que les marges transformantes représentent 30% des marges passives. Leur distribution au sein de domaines océaniques ouverts de façon très oblique ou à l’intersection entre grands domaines reflète des conditions d’initiation spécifiques. 30% des marges transformantes se trouvent notamment en bordure d’un plateau marginal ; un type de bassin à l’histoire double nouvellement défini, qui semble associé à un fort amincissement crustal. Par ailleurs, on montre que les marges transformantes présentent des architectures diverses et sont souvent segmentées. L’étude des plateaux marginaux de Demerara et Guinée a permis de montrer qu’elles se mettent en place au niveau d’un domaine pré-aminci, sans doute guidées par des structures préexistantes. La nature du soubassement des plateaux est discutée : éventails sédimentaires ou volcaniques type SDR. La formation et l’évolution des marges transformantes en bordure des deux plateaux a été accompagnée de déformations intenses à l’approche des frontière océan-continents ainsi que de plusieurs épisodes de soulèvement et subsidence successifs de la bordure transformante, dont les origines et mécanismes sont discutés. / Transform margins form by transform motion between plates during early stages of oceanic spreading. They have been poorly studied in comparison with divergent margins, at least for the last 15 years. The Côte d’Ivoire-Ghana margin represents the best known example of a transform margin and is often considered as a model. However, the lack of a global complete inventory of such margins may lead to underestimate their diversity. Two approaches have been developed in this work. The first one consisted in a compiling world transform margins using a systematic and simple methodology. Those margins have then been compared (physiography, structure). In a second approach we analysed the tectono-sedimentary evolution of the Demerara and Guinea conjugated transform-derived plateaus. The worldwide review of transform margins shows that those represent 30% of the existing passive margins. Their distribution inside very oblique oceanic domains, and at the intersection between oceanic domains of contrasted ages, reflects specific initiation conditions. 30% of those transform margins locate on the edge of marginal plateaus —newly defined type of basins— that seem to be associated with important crustal thinning. Furthermore, this inventory shows that transform margins display a great variety of architectures. The Demerara and Guinea marginal plateaus are bounded by transform margins that occur on an already thinned crust, probably along a preexisting structure. The nature of these plateaus basement is discussed: sedimentary or volcanic SDRs fan-shaped units? During the Equatorial Atlantic opening, the formation and evolution of Demerara and Guinea transform margins were accompanied by intense deformations close to the continent-ocean boundary and by several successive uplift and subsidence phases along the plateaus borders. Their origin and mechanisms are discussed.

To subsidize this proposal, there have been approached themes related to the importance of tourism as an instrument of regional development, the role of financing as a public policy for tourism support and the profile of the sample cities – Baturité, Guaramiranga, Mulungu and Pacoti – where there has been developed a field research to approach the work theme to the reality investigated, through a qualitative research. Under this scope, it has been learnt that the tourism development factor of a locality goes much beyond the credit availability, and must involve the integration of the Region´s municipalities, the orchestration of the federal players and the participation of the local community during tourism planning through a common discussion of the local and state policies to the sustainable development of the activity. / Considerando o papel do financiamento ao turismo como instrumento de política pública, o presente estudo consiste na avaliação do Programa de Apoio ao Turismo Regional (PROATUR) – linha de financiamento do Banco do Nordeste (BNB) com recursos do Fundo Constitucional do Nordeste (FNE) -como uma política de interiorização da atividade turística para a Região do Maciço de Baturité – CE. Para subsidiar tal proposta, são abordados temas relacionados à importância da atividade turística como instrumento de desenvolvimento regional, ao papel do financiamento como uma política pública indutora de apoio ao turismo e ao perfil dos municípios integrantes da amostra – Baturité, Guaramiranga, Mulungu e Pacoti - onde foi realizada uma pesquisa de campo para aproximar o tema do trabalho à realidade investigada, através de pesquisa qualitativa. Neste sentido, verificou-se que, o fator de desenvolvimento turístico de uma localidade vai muito além da disponibilidade de crédito, devendo envolver a integração dos municípios da Região, a concertação das diversas instâncias governamentais e a participação da comunidade local no planejamento turístico, perpassando pelas discussões conjuntas das políticas estaduais e locais para o desenvolvimento sustentável da atividade.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Enxertos ósseos homólogos congelados têm sido documentados apresentando bons resultados clínicos como substituto ao material autógeno nas reconstruções alveolares. Entretanto, dados referentes à incorporação e remodelação destes enxertos não estão disponíveis na literatura. Este estudo tem por objetivo determinar um período ótimo de espera para instalação de implantes em rebordos reconstruídos com enxertos ósseos homólogos em bloco no que se refere à incorporação e reabsorção. 24 pacientes foram submetidos à reconstrução alveolar óssea homóloga previamente à instalação de implantes. Os indivíduos foram alocados randomicamente em um de 3 grupos de acordo com o tempo de espera para o segundo estágio cirúrgico (4, 6 e 8 meses). Análises tomográficas, histológicas e histomorfométricas foram utilizadas a fim de determinar o grau de reabsorção e incorporação dos enxertos nos diferentes intervalos de tempo para cada grupo. Os dados de reabsorção sofrida pelos enxertos demonstraram diferenças estatisticamente significativas para os três intervalos de espera. Da mesma forma, parâmetros histomorfométricos como contagem de osteócitos e quantificação de remanescentes de osso homólogo nas biópsias apresentaram diferenças significativas entre os grupos. De acordo com os dados do presente trabalho, no que diz respeito à remodelação e incorporação, o período mais favorável à instalação dos implantes a curto prazo após recontruções com enxertos homólogos é de 4 meses. / Fresh-frozen homologous bone grafts have been reported achieving good clinical results as a substitute for autogenous bone in alveolar reconstruction. However, data regarding the incorporation and remodeling of these grafts are not available in the literature. The aim of this study is to determine the optimal period for the implant placement in alveolar ridges reconstructed with bone block allografts. 24 patients underwent alveolar ridge reconstruction with homologous bone prior to implant placement. Subjects were randomly assigned into one of three groups according to the waiting time for the second surgical stage (4, 6 and 8 months). Tomographic, histological and histomorphometric analisys were used to determine the rates of grafts resorption and incorporation at different time intervals for each group. Data from graft resorption showed statistically significant differences for the three healing intervals. Similarly, histomorphometric parameters as: osteocytes count and quantification of remaining graft in the biopsies showed significant differences between groups. According to this work, with regard to the remodeling and incorporation, the most favorable the short term period to implant placement after fresh-frozen block allografts ridge reconstruction is 4 months.

O Banco de Abrolhos e os montes submarinos da Cadeia Vitória-Trindade (CVT) são irregularidades que promovem influências no sistema de correntes de contorno oeste local, em especial ao fluxo da Corrente do Brasil (CB), induzindo a formação de meandramentos e vórtices na região. Confinado por essas estruturas ao seu redor, o Embaiamento de Tubarão (ET) compreende uma região em frente à Vitória (20,3°S; 40,3°W) que abriga vórtices ciclônicos cuja formação foi investigada no presente trabalho como sendo influenciada por uma bifurcação da CB nesse sítio. A bifurcação de uma corrente geostrófica é um processo geofísico de interação de um jato e uma parede continental, com a consequente formação de dois jatos secundários – um em cada direção – e que pode ser responsável pela formação de vórtices em bacias parcialmente confinadas (e.g. Mar de Alborão e Mar do Japão). Esse processo foi encontrado no ET a partir de uma recorrente incidência da CB em seu talude continental, identificada com base em resultados de uma simulação numérica de alta resolução espacial e batimetria tratada. Ao que se tenha conhecimento, esta é a primeira descrição de tal processo na região. Os resultados encontrados sugerem que o jato secundário desviado para o interior do ET tenha um papel indispensável na formação e manutenção de dois tipos de vórtices ciclônicos, diferenciados entre si principalmente em tamanho, duração e período de ocorrência. As características desses vórtices e da própria bifurcação mostraram estar sensivelmente ligadas ao padrão de escoamento da CB pelos canais formados entre os montes da CVT. / The transition region from the east to the southeast Brazilian coast, between 19°S and 21°S, shows remarkable geomorphological features that characterizes a complex shelf-break line. The Abrolhos Banks and the Vitória-Trindade Ridge’s (VTR) seamounts are irregularities that promote influences on the system of western boundary currents in this region, specially to the Brazil Current (BC), inducing its meandering and the developing of eddies locally. Confined by these structures around it, the Tubarão Bight (TB) is a region in front of Vitória (20.3°S; 40.3°W) that shelters cyclonic eddies which formation was investigated in this work as influenced by a bifurcation of the BC in this site. The bifurcation of a geostrophic current is a geophysical process of interaction between a jet and a continental boundary that results in the formation of two secondary jets – one in each direction – and that can be responsible for the developing of eddies inside partially confined oceanic basins (e.g Alboran Sea and Sea of Japan). The occurrence of this process was found inside the TB following the impinging of the BC on its continental slope, identified based on numerical modelling results derived from a high-resolution and refined topography simulation. To the extent of our knowledge, this is the first description of such process in this region. This work’s findings suggest that the secondary jet deflected to the TB’s interior is necessary to the developing and maintenance of two kinds of eddies with different size, duration and date of occurrence. These eddies’ characteristics and the bifurcation’s itself were significantly linked to the flowing pattern of the BC through the VTR’s seamounts.

Les superpositions d'ondes modulées en amplitude et en fréquence (modes AM--FM) sont couramment utilisées pour modéliser de nombreux signaux du monde réel : cela inclut des signaux audio (musique, parole), médicaux (ECG), ou diverses séries temporelles (températures, consommation électrique). L'objectif de ce travail est l'analyse et la compréhension fine de tels signaux, dits "multicomposantes" car ils contiennent plusieurs modes. Les méthodes mises en oeuvre vont permettre de les représenter efficacement, d'identifier les différents modes puis de les démoduler (c'est-à-dire déterminer leur amplitude et fréquence instantanée), et enfin de les reconstruire. On se place pour cela dans le cadre bien établi de l'analyse temps-fréquence (avec la transformée de Fourier à court terme) ou temps-échelle (transformée en ondelettes continue). On s'intéressera également à une méthode plus algorithmique et moins fondée mathématiquement, basée sur la notion de symétrie des enveloppes des modes : la décomposition modale empirique. La première contribution de la thèse propose une alternative au processus dit ``de tamisage'' dans la décomposition modale empirique, dont la convergence et la stabilité ne sont pas garanties. \`A la place, une étape d'optimisation sous contraintes ainsi qu'une meilleure détection des extrema locaux du mode haute fréquence garantissent l'existence mathématique du mode, tout en donnant de bons résultats empiriques. La deuxième contribution concerne l'analyse des signaux multicomposantes par la transformée de Fourier à court terme et à la transformée en ondelettes continues, en exploitant leur structure particulière ``en ridge'' dans le plan temps-fréquence. Plus précisément, nous proposons une nouvelle méthode de reconstruction des modes par intégration locale, adaptée à la modulation fréquentielle, avec des garanties théoriques. Cette technique donne lieu à une nouvelle méthode de débruitage des signaux multicomposantes. La troisième contribution concerne l'amélioration de la qualité de la représentation au moyen de la ``réallocation'' et du ``synchrosqueezing''. Nous prolongeons le synchrosqueezing à la transformée de Fourier à court terme, et en proposons deux extensions inversibles et adaptées à des modulations fréquentielles importantes, que nous comparons aux méthodes originelles. Une généralisation du synchrosqueezing à la dimension 2 est enfin proposée, qui utilise le cadre de la transformée en ondelettes monogène. / Many signals from the physical world can be modeled accurately as a superposition of amplitude- and frequency-modulated waves. This includes audio signals (speech, music), medical data (ECG) as well as temporal series (temperature or electric consumption). This thesis deals with the analysis of such signals, called multicomponent because they contain several modes. The techniques involved allow for the detection of the different modes, their demodulation (ie, determination of their instantaneous amplitude and frequency) and reconstruction. The thesis uses the well-known framework of time-frequency and time-scale analysis through the use of the short-time Fourier and the continuous wavelet transforms. We will also consider a more recent algorithmic method based on the symmetry of the enveloppes : the empirical mode decomposition. The first contribution proposes a new way to avoid the iterative ``Sifting Process'' in the empirical mode decomposition, whose convergence and stability are not guaranteed. Instead, one uses a constrained optimization step together with an enhanced detection of the local extrema of the high-frequency mode. The second contribution analyses multicomponent signals through the short-time Fourier transform and the continuous wavelet transform, taking advantage of the ``ridge'' structure of such signals in the time-frequency or time-scale planes. More precisely, we propose a new reconstruction method based on local integration, adapted to the local frequency modulation. Some theoretical guarantees for this reconstruction are provided, as well as an application to multicomponent signal denoising. The third contribution deals with the quality of the time-frequency representation, using the reassignment method and the synchrosqueezing transform: we propose two extensions of the synchrosqueezing, that enable mode reconstruction while remaining efficient for strongly modulated waves. A generalization of the synchrosqueezing in dimension 2 is also proposed, based on the so-called monogenic wavelet transform.
