Abstract:
A brief explanation of RNA and its general structure on dierent levels is given. The standard continuous Frenet frame is explained. A discrete version of the Frenet frame is explained in detail and constructed for a piecewise linear curve. The results of the application of the discrete Frenet frame to RNA is shown in the form of several distributions. An analysis of these distributions is conducted and gives some results regarding tiny structures in RNA.

Abstract:
The present study focuses on developing a Frenet-Serret frame and the Apollonian Window. In the first part of the study Apollonian disks are generated for first four generations by developing visual basic codes in excel. For the second part of the study, three orthonormal basis vectors, namely, tangent, normal, and binormal vectors have been calculated for the tangent points of Apollonian discs for the first three generations. Equations of the Normal, Osculating and Rectifying planes and Taylor Series approximation have been calculated for specific theta. Because Apollonian Window consists of planar curves with constant curvature, torsion is nowhere present. The planar Frenet-Serret Equations for the first three generations for the Apollonian Window is also shown.

Abstract:
Den här uppsatsen visar hur fyra kvinnliga författare debutromaner, från 1891-2000, har blivit mottagna. Undersökningen diskuterar hur kritiker förhåller sig till verken och författarnas kön. Undersökningen vill visa på hur kritikernas förhållningsätt till kvinnliga författare har förändrats under ett sekel. Vidare studeras vilka tendenser som påvisar att författarna har blivit recenserade med utgångspunkt i traditionella könsmönster.   Vår teoretiska utgångspunkt är genus och uppsatsens metodologiska tillvägagångssätt utgörs av Ruth Wodaks definition av kritisk diskuranalys (CDA).  Resultatet visar att normen kring kvinnans ställning i samhället präglar hur litteraturkritiken bemöter kvinnliga författare. Den förändring som har skett under hundra år avspeglas även i mottagandet av romanerna.   Summeringen är kritiken har tidigare haft ett tydligt fokus på författarens kön och en förmyndarartad hållning. I recensionerna av de senare verken från sent 50-tal och framåt är istället innehållet och språket i fokus och författarens kön har en underordnad betydelse.

Resumo: A teoria local de curvas da Geometria Diferencial no plano e no espaço euclidiano é bem conhecida (vide referências como [4] e [13]). Este trabalho consiste de uma generalização desta teoria usando métricas arbitrárias. Tal generalização é feita substituindo a matriz identidade que define o produto interno usual por outra matriz quadrada, simétrica e positiva definida. Com este novo produto interno, são estudados conceitos como vetor tangente, vetor normal, vetor binormal, fórmulas de Frenet, curvatura e torção
Abstract: The local theory of curves of the Differential Geometry in the Euclidean plane and euclidean space is well known (see references as [4] and [13]). This work consists of a generalization of this theory using arbitrary metrics. Such generalization is made replacing the identity matrix which defines the usual inner product with another square matrix, symmetrical and positive defined. With this new inner product, concepts like tangent vector, normal vector, binormal vector, Frenet's formulas, curvature and torsion are studied

Abstract:
Le but de cette thèse est d’étudier profondément le repliement des protéines, au moyendes concepts d’invariance de jauge et d’universalité. La structure de jauge émerge del’équation de Frenet qui est utilisée pour décrire la forme de la chaîne principale de laprotéine. Le principe d’invariance de jauge conduit à une fonctionnelle d’énergieeffective pour une protéine, développée dans le but d’extraire les propriétésuniverselles des protéines repliées durant la phase d’effondrement, et qui estcaractérisée par la loi d’échelle du rayon de giration au niveau tertiaire de la structureprotéique. Dans cette thèse, on étudie l’existence d’une large universalité au niveausecondaire de la structure protéique. La fonctionnelle d’énergie invariante de jaugealliée à l’équation de Frenet discrète conduit à une solution solitonique, identifiéecomme un motif hélice-boucle-hélice dans la protéine
The purpose of this thesis is to investigate protein folding, by means of the general concepts of gauge invariance and universality. The gauge structure emerges in the Frenet equation which is utilized to describe the shape of protein backbone. The gauge invariance principle leads us an effective energy functional for a protein, which bas been found to catch the universal properties of folded proteins in their collapse phase,characterized by the scaling law of gyration radius on the tertiary level of proteinstructure. In this thesis, the existence of wide universality on the secondary level of protein structure is investigated. The synthesis of the gauge-invariant energy functional with the discrete Frenet equation leads to a soliton solution, which is identified as the helix-loop-helix motif in protein

This paper proposes to make use of GeoGebra Software as a tool in the study of flat curves. The Software was chosen because it is a powerful tool in teaching learning at all levels of Mathematics because it works with Algebra and Geometry, allowing the user to perform algebraic and graphical operations in the same interface. The topics covered include the parameterized flat curves up to the study of the Frenet benchmark, making Geogebra an important tool for the study and visualization of the concepts covered. With the help of the Software we can better analyze the curves through their graphs.

Dada la proliferación de propuestas artísticas que buscan un acercamiento más directo con la realidad, a través de estrategias con las que no suele estar vinculado el arte ligado a la tradición moderna, mediante experimentos de vida en común, y vías alternativas para la circulación y consumo del arte, la presente investigación tuvo como objetivo desarrollar un análisis a las condiciones bajo las cuales se han desplegado dichas propuestas, generando así un panorama mucho más amplio que permita responder a las dudas que surgen cuando se intenta un acercamiento a ellas. El análisis realizado fue hecho a partir de la descripción y posterior estudio de un pequeño grupo de proyectos personales realizados entre 2004 y 2009, en los cuales fue posible identificar ciertas características propias de un panorama cultural, social y económico en crisis, que de una u otra forma han propiciado la aparición de microutopías sociales que resultaban difíciles de imaginar en condiciones modernas, y que actualmente pueden caracterizar al tipo de proyectos que se han analizado a lo largo de estas páginas

Abstract:
This thesis work presents a model predictive control (MPC) based trajectory planner forhigh speed lane change and low speed parking scenarios of autonomous four wheel steering(4WS) vehicle. A four wheel steering vehicle has better low speed maneuverabilityand high speed stability compared with normal front wheel steering(FWS) vehicles. TheMPC optimal trajectory planner is formulated in a curvilinear coordinate frame (Frenetframe) minimizing the lateral deviation, heading error and velocity error in a kinematicdouble track model of a four wheel steering vehicle. Using the proposed trajectory planner,simulations show that a four wheel steering vehicle is able to track different type ofpath with lower lateral deviations, less heading error and shorter longitudinal distance.

Abstract:
La prise en compte de l'heterogeneite spatiale des milieux et la necessite de comprendre les processus lies au maintien ou a l'extinction des especes dans leur milieu a pris une grande importance tant en biologie de la conservation qu'en ecologie et en evolution. Le concept de metapopulation s'est avere essentiel pour aborder ces problemes et a souligne le role clef de la dispersion. Dans ce travail, en integrant une approche a l'echelle de la metapopulation, nous nous interessons principalement au determinisme de ce trait d'histoire de vie puis aux consequences de la dispersion sur la diversite genetique et la dynamique des populations. Une approche a la fois theorique et experimentale dans des populations de frenes a fleurs situees dans la region de montpellier est menee. D'une part, dans ces populations de frenes a fleurs, nous nous interessons a l'aptitude a disperser des samares relativement a l'age des populations et a l'age des individus. Nous montrons que, dans ces populations, le comportement de dispersion est plutot de nature plastique. D'autre part, pour aborder les consequences de l'impact du processus de colonisation sur la structuration de la diversite genetique, nous etudions la diversite genetique presente dans ces populations de frenes a fleurs a l'aide de marqueurs microsatellites. Nos resultats montrent qu'il existe un fort niveau de diversite genetique dans ces populations et une faible differenciation entre populations, ce qui va dans le sens d'autres etudes experimentales et theoriques mais ne permet pas de conclure sur l'hypothese de plasticite. Enfin, nous nous interessons aux consequences ecologiques de la dispersion en etudiant a l'aide d'un modele theorique les conditions de maintien et d'extinction d'une metapopulation dans son habitat ou paysage. En developpant une approche analytique, nous abordons l'influence de la structure du paysage et les consequences d'une modification du paysage sur la dynamique de la metapopulation.

O objetivo deste trabalho é explorar os potenciais teóricos do conceito de aceleração social desenvolvido por Hartmut Rosa, no sentido do diagnóstico que este elabora sobre a experiência do tempo na contemporaneidade, derivando daí um modelo crítico particular. Deste diagnóstico busca-se ressaltar uma nova formação subjetiva, cujas tendências imanentes convergem para a crescente difusão de psicopatologias, que, por sua vez, reconfiguram o mal-estar na cultura. O caminho entre a teoria da aceleração social e o delineamento destas tendências se faz em três capítulos. No primeiro, o conceito de estabilização dinâmica é tomado como ordenador expositivo das categorias analíticas utilizadas por Rosa para constituir sua teoria fundamental e, com ela, fundar uma nova leitura do conceito de modernidade. No segundo são expostos os fenômenos que indicam, para Rosa, o ponto de viragem da modernidade para a modernidade tardia, e a partir deles elabora-se a base fenomênica das novas modalidades de integração social e das novas estratégias subjetivas que as acompanham. Por fim, no terceiro capítulo realiza-se uma reflexão sociológico-filosófica acerca do conceito de alienação derivado da teoria da aceleração social, e que denota uma estrutura patológica da subjetividade contemporânea. Da exposição deste conceito, elaborada em três instâncias, constituem-se os traços para um modelo crítico fundado no sofrimento implicado pela predicação das ações pela lei da aceleração social.
This work aims at exploring the theoretical potentials of the concept of social acceleration developed by Hartmut Rosa, towards the current time experience diagnosis he has elaborated, deriving from this a particular critical model. Departing from this diagnosis a new subjectivity formation is attempted to be highlighted, whose inner trends points to the spreading diffusion of psychopathologies which, by its turn, reset the culture discontent. The way between the theory of social acceleration and the drawing of these new tendencies is made by three chapters. In the first one, the concept of dynamic stabilisation is taken as an exposition organizer of the analytical categories used by Rosa in order to build its base theory and, with it, to ground a new reading of the modernity concept. In the second, there are exposed the phenomena that indicates, in Rosa’s view, the turning point between modernity and late-modernity, and from them the phenomenological base of new social integration modalities and its following subjective strategies is elaborated. Finally, at the third chapter, a sociological-philosophical reflection on the concept of alienation derived from the social acceleration theory, which denotes a pathological structure of the contemporary subjectivity, is operated. From this concept exposition, detailed in three dimensions, the traces of a critical model, grounded on the suffering caused by the prediction of the actions by the social acceleration law, is constituted.

Abstract:
Proteins in nature fold to one dominant native structure. Despite being a heavily studied field, predicting the native structure from the amino acid sequence and modeling the folding process can still be considered unsolved problems. In this thesis I present a new approach to this problem with methods borrowed from theoretical physics. In the first part I show how it is possible to use a discrete Frenet frame to define the discrete curvature and torsion of the main chain of the protein. This method is then extended to the side chains as well. In particular I show how to use the discrete Frenet frame to produce a statistical distribution of angles that works in similar fashion as the commonly used Ramachandran plot and side chain rotamers. The discrete Frenet frame displays a gauge symmetry, in the choice of basis vectors on the normal plane, that is reminiscent of features of Abelian-Higgs theory. In the second part of the thesis I show how this similarity with Abelian-Higgs theory can be translated into an effective energy for a protein. The loops of the proteins are shown to correspond to solitons so that the whole protein can be constructed by gluing together any number of solitons. I present results of simulating proteins by minimizing the energy, starting from a real line or straight helix, where the correct native fold is attained. Finally the model is shown to display the same phase structure as real proteins.

Abstract:
In order to perform a specific function, a protein needs to fold into the proper structure. Prediction the protein structure from its amino acid sequence has still been unsolved problem. The main focus of this thesis is to develop new approach on the protein structure modeling by means of differential geometry and integrable theory. The start point is to simplify a protein backbone as a piecewise linear polygonal chain, with vertices recognized as the central alpha carbons of the amino acids. Frenet frame and equations from differential geometry are used to describe the geometric shape of the protein linear chain. Within the framework of integrable theory, we also develop a general geometrical approach, to systematically derive Hamiltonian energy functions for piecewise linear polygonal chains. These theoretical studies is expected to provide a solid basis for the general description of curves in three space dimensions. An efficient algorithm of loop closure has been proposed.

Oxyphylla, il porte un site de restriction ecori supplementaire situe dans l'espaceur intergenique et permet de differencier les deux especes. Chaque type d'unite montre des variations de longueur. La taille de l'unite d'adnr est determine par l'endonuclease ecorv. Elle varie de 11 kb a 14,5 kb. Une region de 6,8 kb (clone pe1g12) correspondant a l'espaceur intergenique (igs) de f. Excelsior a ete isolee et partiellement caracterisee. Nous observons la presence de deux familles de sous unites repetees delimitees par des sites de restriction pour l'enzyme haeiii. Ces sous unites de 33 bp et 40 bp ont ete sous clonees et sequencees. Les deux familles partagent une sequence commune de 23 bp. Elles representent environ 70% de l'igs. Une organisation de l'igs de f. Excelsior est proposee. La combinaison enzyme/sonde, ecori/pe1g12 permet de differencier chaque espece par un profil autoradiographique propre. Nous avons utilise ces profils espece-specifique comme references pour comparer des frenes d'une zone ou les deux especes f. Excelsior et f. Oxyphylla coexistent. Nous revelons des cas d'introgression du genome de f. Oxyphylla chez f. Excelsior qui ne sont pas detectables par l'utilisation des caracteres morphologiques. Les sous unites repetees de l'igs de f.

Abstract:
Actuellement les boisements feuillus post-culturaux se developpent rapidement dans les zones ou l'agriculture et l'elevage sont en repli. Dans les alpes ce phenomene a ete peu etudie. L'approche proposee s'articule autour de trois etudes complementaires: 1 une analyse de la ressource existante dans quelques regions forestieres a partir des donnees de l'inventaire forestier national, 2 une analyse structurale des boisements de maurienne et tarentaise a partir des donnees dendrometriques recueillies sur le terrain, 3 une analyse de la place de ces formations feuillues dans le processus de succession vegetale. En fait, la dynamique de ces formations apparait etre le reflet des interactions locales entre l'action de l'homme, le climat et les conditions de milieu. Ainsi d'une region a l'autre la repartition des trois especes etudiees (frene, erable et merisier) peut varier considerablement, depuis une dispersion dans des peuplements forestiers occupant de larges surfaces jusqu'a la concentration sur de petites surfaces, sans oublier le developpement de vrais peuplements feuillus post-agricoles occupant les adrets des alpes intermediaires. Une telle diversite de situations a des consequences pour la gestion. En fait, ces peuplements peuvent, selon les circonstances, presenter un avenir sylvicole, accroitre la biodiversite, ameliorer le cadre de vie, seule une connaissance a la fois ecologique et sylvicole de ces boisements doit permettre d'optimiser leur utilisation dans la gestion de l'espace rural

Abstract:
La plupart des méthodes de surveillance des systèmes sont basées sur l'analyse et la caractérisation de grandeurs physiques qui sont par nature tridimensionnelles. Tracées dans un repère euclidien à trois dimensions, ces grandeurs parcourent en fonction du temps une trajectoire dont les caractéristiques géométriques sont représentatives de l'état du système surveillé. Les techniques classiques de surveillance des systèmes étudient les grandeurs mesurées composante par composante, sans prendre en compte leur nature tridimensionnelle et les propriétés géométriques de leur trajectoire. Une part importante de l'information est ainsi ignorée. Dans le cadre de ce travail de recherche, on se propose de développer une méthode d'analyse et de traitement de grandeurs à trois composantes permettant de mettre en évidence les spécificités géométriques des données et de fournir une information complémentaire pour la surveillance des systèmes. La méthode proposée a été appliquée à deux cas différents : la surveillance des creux de tension des réseaux de puissance triphasés et la surveillance des défauts de roulement des machines électriques tournantes. Dans ces deux cas, les résultats obtenus sont prometteurs et montrent que les indicateurs géométriques estimés mènent à de l'information complémentaire qui peut être utile pour la surveillance des systèmes
Most methods for condition monitoring are based on the analysis and characterization of physical quantities that are three-dimensional in nature. Plotted in a three-dimensional Euclidean space as a function of time, these quantities follow a trajectory whose geometric characteristics are representative of the state of the monitored system. Usual techniques of condition monitoring study the measured quantities component by component, without taking into account their three-dimensional nature and the geometric properties of their trajectory. A significant part of the information is thus ignored. In this research work, we would therefore like to develop a method for the analysis and processing of three-component quantities capable of highlighting the special geometric features of such data and providing complementary information for condition monitoring. The proposed method has been applied to two different cases: voltage dips monitoring in three-phase power networks and bearing faults monitoring in rotating electrical machines. In this two cases, the results obtained are promising and show that the estimated geometric indicators lead to complementary information that can be useful for condition monitoring

A teoria local de curvas da Geometria Diferencial no plano e no espaço euclidiano é bem conhecida (vide referências como [4] e [13]). Este trabalho consiste de uma generalização desta teoria usando métricas arbitrárias. Tal generalização é feita substituindo a matriz identidade que define o produto interno usual por outra matriz quadrada, simétrica e positiva definida. Com este novo produto interno, são estudados conceitos como vetor tangente, vetor normal, vetor binormal, fórmulas de Frenet, curvatura e torção

The main aim of this work is a study about twistings points and Darboux vertices of n-space curves. We define the concept of twisting of a n-space curve as flattening point of its tangent indicatrix and show that is equivalent to having higher order of contact with some generalized helix. In the three dimensional case we establish a relation between twisting points and Darboux vertices. We also obtain a version of the four vertex theorem for space closed curves involving such points.
O presente trabalho destina-se a um estudo sobre pontos helicoidais (twistings) e vértices de Darboux de curvas no espaço euclidiano n-dimensional. Pontos helicoidais são pontos de aplainamento (flattening) da indicatriz tangente da curva. Mostramos que nestes pontos a curva tem maior contato com alguma hélice generalizada. No caso de curvas no espaço tridimensional, estabelecemos uma relação entre pontos helicoidais e vértices de Darboux. Obtemos também uma versão do teorema dos quatro vértices para curvas fechadas no espaço envolvendo tais pontos.

A região do complexo bucomaxilofacial freqüentemente é acometida por doenças e variações de normalidade, algumas das quais apresentam notável relação com grupos étnicos e raciais. Os estudos sobre a distribuição das doenças bucais e variações de normalidade em comunidades indígenas normalmente são direcionados principalmente para o estudo da cárie dentária nas crianças e doenças periodontais em adultos, negligenciando-se ampla gama de demais doenças existentes na boca. Assim, foi objetivo desse estudo, avaliar as condições de saúde bucal de oito etnias (Umutina, Paresi, Bororo, Bakairi, Kayabi, Irantxe, Nambikwara and Terena) que residem na terra indígena Umutina, no Estado de Mato Grosso. Um total de 291 índios, de ambos os sexos e com idade variando de 1 a 96 anos, foram examinados, sendo que alterações de normalidade ou patologias bucais foram observadas em um total de 132 indivíduos,evidenciando uma elevada ocorrência de anquiloglossia, a qual esteve presente em 108 casos (37,11%), seguida de glossite migratória benigna em 5 casos (1,72%); tórus mandibular e candidose em 3 casos (1,03%), dentre outras. Nenhuma lesão de caráter maligno foi identificada na referida população. Apesar da elevada freqüência de anquiloglossia na Reserva Indígena Umutina, a mesma não parece ser responsável por alterações associadas à fonação, mastigação, presença de diastema e problemas periodontais, uma vez que essas alterações foram observadas em baixa freqüência e não foram motivos de queixas da população. As condições dentárias foram avaliadas com o objetivo de identificar a prevalência de cárie dentária e necessidade de tratamento odontológico das crianças da aldeia Umutina, por meio de um estudo epidemiológico transversal. Para análise da cárie dentária foram utilizados: os índices de dentes cariados, perdidos e obturados (CPOD) para...
The oromaxillofacial complex is frequently envolved by diseases and variations from normality, some of which closely related to ethnical and racial groups. Studies on the distribution of oral diseases and variations from normality in Indian communities are generally directed mainly to the study of dental caries in the children and periodontal diseases in the adults, disregarding a wide range of other oral diseases. Thus, the aim of this study was to evaluate the oral health conditions of eight ethnic groups living in the Umutina Indian Reservation, in the State of Mato Grosso, Brazil. The total of 291 Indians, of both generes, with ages ranging from 1 to 96 years, were examined and were found between them 132 abnormalities and/or oral diseases, evidencing a high occurrence of ankyloglossia, which was present in 108 cases (37.11%), followed by benign migratory glossitis in 5 cases (1.72%); mandibular torus and candidosis in 3 cases (1.03%) among others. No malign lesion was identified in that population. Even thought the high frequency of the ankyloglossia in the ethnicities living in the Umutina Indian reservation, it does not seem to be responsible for alterations associated to phonation, mastication, presence of diastema and periodontal problems, since those alterations were observed with a low frequency and were not reason for complaint from the population. The dental conditions were evaluated with the aim to identify the prevalence of dental caries and the need of dental treatment in children from Umutina Village using a transversal epidemiological study. To analyze dental caries prevalence the decayed, missing, and filled teeth (DMFT) or decayed, extracted, and filled teeth (deft) indexes were used for, respectively, permanent or primary dentition and the need of treatment index.

Abstract:
Este estudo teve por objetivo validar o Protocolo de avaliação do frênulo da língua em bebês. Para isso, a partir do cálculo amostral, foi aplicado o protocolo em 100 bebês saudáveis, nascidos a termo, com 30 dias de vida, em amamentação exclusiva. O processo de validação consistiu da análise da validade de conteúdo, de critério e de construto, bem como da confiabilidade, sensibilidade, especificidade, valor preditivo positivo e negativo. A validade de conteúdo foi realizada por três examinadores, por meio da classificação de cada item quanto à clareza e posterior aplicação do Índice de Validação do Conteúdo. As avaliadoras sugeriram modificações no protocolo, por consenso, possibilitando obter a versão final. Para a validade de critério, comparou-se o Protocolo de avaliação do frênulo da língua em bebês com o instrumento Bristol Tongue Assessment Tool (BTAT). A validade de construto foi analisada a partir da comparação dos escores do protocolo aplicado nos bebês com 30 e 75 dias. As avaliações foram realizadas por duas fonoaudiólogas especialistas em Motricidade Orofacial (denominadas A1 e A2), devidamente treinadas e calibradas, por meio da análise das filmagens realizadas durante a aplicação do protocolo, para verificação da concordância entre examinadores, bem como definição dos valores de sensibilidade, especificidade e valores preditivos. Para a análise da concordância intra-avaliador foi realizado o teste/reteste de 20% da amostra pela A2. Quanto ao tratamento estatístico, para a análise de concordância intra e entre avaliadores, foram utilizados o Coeficiente de Correlação Intraclasse e o cálculo do erro do método. Para análise da validade de construto foram aplicados os testes de Wilcoxon e Mann-Whitney. O nível de significância adotado em todos os testes foi de 5%. Houve 100% de concordância na validação do conteúdo. A validade de critério apresentou correlações fortes dos itens correspondentes do Protocolo de avaliação do frênulo da língua em bebês e do instrumento BTAT, sendo o valor do coeficiente de correlação de Spearman igual a -0,997. Os resultados obtidos evidenciaram uma concordância muito boa intra e entre avaliadores, com valores baixos de erro casual e valores de p>0,05 (evidenciando que não há diferença entre a análise dos avaliadores) e Coeficiente de Correlação Intraclasse maior que 0,75; mostrando ainda, uma capacidade significativa do protocolo em mensurar as mudanças resultantes da frenotomia lingual, pela história clínica, avaliação anatomofuncional e avaliação da sucção não nutritiva e nutritiva (p<0,05). Quando comparados os resultados dos bebês com alteração do frênulo lingual (grupo experimental) e sem alteração (grupo controle), com 30 e 75 dias, houve diferença nos escores parciais e no escore total do exame clínico e do protocolo completo. Os índices de sensibilidade, especificidade e valores preditivos positivo e negativo foram 100%. A ocorrência das alterações do frênulo lingual nesse estudo foi de 21%. Concluiu-se, com este estudo, que o Protocolo de avaliação do frênulo da língua em bebês mostrou ser um instrumento válido e confiável de avaliação, assegurando acurácia em diagnosticar as alterações do frênulo lingual dentro dos parâmetros investigados, podendo ser aplicado por diferentes avaliadores, desde que os mesmos sejam capacitados e treinados para sua aplicação.
The aim of this study was to validate the lingual frenulum Protocol for infants. Based on the results from the sample size calculation, the protocol was administered to 100 healthy full-term infants, who were being exclusively breastfeed, at 30 days of life. The validation process included the analysis of content validity, criterion validity, construct validity, reliability, sensitivity, specificity, positive predictive value, negative predictive value. The content validity was determined by the judgment of three experts, who rated the clarity of each item, and by a Content Validity Index (CVI) determination. By consensus, the examiners suggested some modifications for the final version. The criterion validity was measured by comparing the Lingual Frenulum Protocol for Infants and the Bristol Tongue Assessment Tool (BTAT). The construct validity was performed by comparing the scores of the protocol of the control group and of the experimental group before and after surgery. The assessments were performed by two Speech Language Pathologists, experienced in Orofacial Motricity (A1 and A2), who were trained and calibrated. Analyses of the images collected during the administration of the protocol and the clinical history were performed in order to verify the agreement between the examiners as well as the definition of sensitivity, specificity, positive predictive value, and negative predictive value. Intra-rater agreement analysis was performed by comparing data from assessment and re-assessment of 20% sample conducted by A2. Regarding statistical treatment, the Intraclass Correlation Coefficient (ICC) and calculation of error of method were used. The Wilcoxon test and Mann-Whitney were used for the analysis of the construct validity. The significance level of 5% (p<0.05) was adopted in all analyses. The agreement percentage for content validation was 100%. The criterion validity demonstrated strong correlation of the corresponding items of the lingual frenulum Protocol for infants and BTAT (Spearmans value = -0.997). The results demonstrated very good inter and intra-rater agreement with low values of random error and p>0.05 (indicating that there is no difference between the analysis of the evaluators) and Intraclass Correlation Coefficient was greater than 0.75. Moreover, the results indicated that the protocol clinical history, anatomo-functional evaluation, nutritive and non-nutritive suction has a significant capacity to assess changes after lingual frenotomy (p<0.05). Comparison of the results from the assessment of infants with lingual frenulum alteration (experimental group) and without lingual frenulum alteration (control group) at 30 and 75 days demonstrated the difference in both, the partial scores and total scores of clinical examination and full protocol. The values of sensitivity, specificity, positive predictive value, negative predictive value were 100%. Lingual frenulum alteration occurrence in this research was 21%. The study concluded that the lingual frenulum Protocol for Infants has demonstrated to be a valid and reliable assessment tool, ensuring accuracy to diagnose lingual frenulum alterations within the investigated parameters. It may be administered by other professionals provided that they are qualified and trained to administer the protocol.

Resumo: A região do complexo bucomaxilofacial freqüentemente é acometida por doenças e variações de normalidade, algumas das quais apresentam notável relação com grupos étnicos e raciais. Os estudos sobre a distribuição das doenças bucais e variações de normalidade em comunidades indígenas normalmente são direcionados principalmente para o estudo da cárie dentária nas crianças e doenças periodontais em adultos, negligenciando-se ampla gama de demais doenças existentes na boca. Assim, foi objetivo desse estudo, avaliar as condições de saúde bucal de oito etnias (Umutina, Paresi, Bororo, Bakairi, Kayabi, Irantxe, Nambikwara and Terena) que residem na terra indígena Umutina, no Estado de Mato Grosso. Um total de 291 índios, de ambos os sexos e com idade variando de 1 a 96 anos, foram examinados, sendo que alterações de normalidade ou patologias bucais foram observadas em um total de 132 indivíduos,evidenciando uma elevada ocorrência de anquiloglossia, a qual esteve presente em 108 casos (37,11%), seguida de glossite migratória benigna em 5 casos (1,72%); tórus mandibular e candidose em 3 casos (1,03%), dentre outras. Nenhuma lesão de caráter maligno foi identificada na referida população. Apesar da elevada freqüência de anquiloglossia na Reserva Indígena Umutina, a mesma não parece ser responsável por alterações associadas à fonação, mastigação, presença de diastema e problemas periodontais, uma vez que essas alterações foram observadas em baixa freqüência e não foram motivos de queixas da população. As condições dentárias foram avaliadas com o objetivo de identificar a prevalência de cárie dentária e necessidade de tratamento odontológico das crianças da aldeia Umutina, por meio de um estudo epidemiológico transversal. Para análise da cárie dentária foram utilizados: os índices de dentes cariados, perdidos e obturados (CPOD) para... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: The oromaxillofacial complex is frequently envolved by diseases and variations from normality, some of which closely related to ethnical and racial groups. Studies on the distribution of oral diseases and variations from normality in Indian communities are generally directed mainly to the study of dental caries in the children and periodontal diseases in the adults, disregarding a wide range of other oral diseases. Thus, the aim of this study was to evaluate the oral health conditions of eight ethnic groups living in the Umutina Indian Reservation, in the State of Mato Grosso, Brazil. The total of 291 Indians, of both generes, with ages ranging from 1 to 96 years, were examined and were found between them 132 abnormalities and/or oral diseases, evidencing a high occurrence of ankyloglossia, which was present in 108 cases (37.11%), followed by benign migratory glossitis in 5 cases (1.72%); mandibular torus and candidosis in 3 cases (1.03%) among others. No malign lesion was identified in that population. Even thought the high frequency of the ankyloglossia in the ethnicities living in the Umutina Indian reservation, it does not seem to be responsible for alterations associated to phonation, mastication, presence of diastema and periodontal problems, since those alterations were observed with a low frequency and were not reason for complaint from the population. The dental conditions were evaluated with the aim to identify the prevalence of dental caries and the need of dental treatment in children from Umutina Village using a transversal epidemiological study. To analyze dental caries prevalence the decayed, missing, and filled teeth (DMFT) or decayed, extracted, and filled teeth (deft) indexes were used for, respectively, permanent or primary dentition and the need of treatment index. Statistical analysis was done with the software GraphPad Prism. The Mann Whitney analysis was used with... (Complete abstract click electronic access below)

Abstract:
Centrée sur la thématique de la « fureur héroïque » développée dans le dernier ouvrage écrit en langue italienne par Giordano Bruno, De gli eroici furori (1585), cette recherche explore une double problématique suivant deux perspectives. D’une part, du point de vue historique, quels sont les schèmes philosophiques qui peuvent être considérés comme des conditions de possibilité de l’émergence de la figure du Furioso, le philosophe-poète dont les poèmes et leur commentaire philosophique nous font suivre l’itinéraire affectif et cognitif dans sa poursuite d’une union naturelle et rationnelle avec le principe infini du réel ? Suivant une méthode archéologique, il s’agit de retrouver dans les strates de la culture philosophique des traces précises et exemplaires de la mise en place, de la transmission et de la transformation de ces schèmes fondamentaux chez des auteurs de l’Antiquité, du Moyen Âge ou de la Renaissance. D’autre part, du point de vue conceptuel, comment une expérience psychologique telle que cette rencontre noético-amoureuse, qui n’est jamais totalement aboutie en raison de la disproportion entre « le sujet » et « l’objet », et qui se présente, néanmoins, comme une dissolution de soi dans la disparition de la distinction entre sujet et objet, met-elle en oeuvre, paradoxalement, une constitution de soi ?
Focused on the theme of the “heroic frenzy” developed in Giordano Bruno’s last opus written in Italian language, De gli eroici furori (1585), this work explores a double issue from two perspectives. On the one hand, from an historical point of view, what are the philosophical schemes that may be considered as conditions of possibility for the emergence of the Furioso’s figure, the philosopher-poet whose poems and their commentary lead through a path of affects and knowledge in his own intellectual pursuit of a natural and rational bonding with the infinite principle of reality? Following an archeological method, specific and exemplary traces of these fundamental schemes are found within layers of philosophical culture, throughout works of authors of Antiquity, Middle Ages or Renaissance who set, relayed and modified them. On the other hand, from a conceptual point of view, the process of the Furioso’s psychological experience is studied. His both noetic and loving encounter with the Principle is never completely fulfilled because of the disproportion between “the subject” and “the object”. Nevertheless, it is presented as a dissolution of self by ending the distinction between the subject and the object. How does this experience paradoxically implements a constitution of self?

Abstract:
Gerard Genette offered a comprehensive, structurally informed theory of narrative in his book Narrative Discourse, An Essay in Method. While the “grammatical” basis of his framework – he identified parts of narrative with parts of speech – is today less in vogue, many of his other concepts and terms remain highly useful in the analysis of a wide range of narrative, be they of literary, cinematic, or of other origin. Useful features of this work are that it drew on various traditions that preceded its publication, but was also discussed and refined in the years that followed. Indeed a number of his propositions seem in need of modification, and these modifications are here summarized and added to. A further advantage to his method, especially when compared to other modes of critical enquiry, is that they are firmly based in the texture and nature of the object being studied. That said, they also work well with other approaches which are less directly tied to the story. The work of Alfred Hitchcock provides a case study in the illustration of both the descriptive power of Genette’s ideas, and their ability to merge well with other approaches.

This thesis consists of two parts: a creative project, entitled Frenzy: The Story of the Mount Rennie Outrage, and a dissertation, entitled No end of a yarn: Reading the Mount Rennie Outrage. The first part is a narrative history of events that occurred in Sydney over a period of four months, from 9th September 1886, when 16-year-old Mary Jane Hicks was raped by members of a larrikin mob near Waterloo, until 8th January 1887, when four of the teenage rapists were hanged. Most of the material I have researched to write this history is derived from three key sources: original records of the crime and subsequent trial held at State Records in Western Sydney; original records from the archives of the New South Wales Department of Corrective Services at Silverwater Jail; and contemporary newspaper reports held in various forms at the State Library of New South Wales. My dissertation is a study of how the Outrage has been interpreted, both directly and indirectly, by participants, journalists, politicians, novelists and others. It suggests the existence of two contradictory impulses - a desire to sensationalise the facts and a contrary desire to suppress them – that, to varying degrees, have shaped every reading of the Outrage. It examines these impulses in the light of social and sexual anxieties of the period as reflected, especially, in journalism and popular fiction. It proposes two “authorised” readings of the case — as the tragedy of Mary Jane Hicks or, alternatively, as the tragedy of the youths hanged or imprisoned for raping her — and asks whether other, more flexible, interpretations are possible. It ends with some reflections about the wider processes by which history is read and written.

Objetivo Aprofundar o conhecimento do uso do laser em medicina dentária/odontopediatria. O foco principal é a frenectomia com recurso ao laser, comparando-a com a técnica convencional. Metodologia A revisão da literatura teve como base uma pesquisa bibliográfica de artigos publicados em revistas científicas disponíveis em bases de dados eletrónicas. Foram incluídos artigos que relacionassem o uso do laser em frenectomia, publicados entre 2000 e 2018 apenas em língua Espanhola, Inglesa e Portuguesa. Descrição do tema O laser foi introduzido na medicina dentária com o objetivo de ultrapassar algumas desvantagens impostas pelos métodos convencionais. A terapia laser constitui um recurso inovador para uma estratégia preventiva e terapêutica eficaz em odontopediatria. Os freios orais apresentam muitas vezes alterações de forma, constituição e inserção sendo necessário, nestes casos, por vezes, realizar uma frenectomia. O laser é uma boa alternativa à cirurgia convencional.
Objectives To deepen the knowledge of the use of the laser in dental medicine / pediatric dentistry. The main focus is the frenectomy using the laser, comparing it with the conventional technique. Material and Methods The literature review was based on a bibliographical research of articles published in scientific journals available in electronic databases. We included articles that related the use of the laser in frenectomy, published between 2000 and 2018 only in Spanish, English and Portuguese. Development The laser was introduced in dentistry with the aim of overcoming some of the disadvantages imposed by conventional methods. Laser therapy is an innovative resource for an effective preventive and therapeutic strategy in pediatric dentistry. The oral braces often present changes in shape, constitution and insertion, and in these cases, sometimes, a frenectomy is necessary. Laser is a good alternative to conventional surgery.

Este trabalho foi desenvolvido com o intuito de estudar as propriedades locais de curvas e superfícies no plano e espaço euclidianos, expressando-as parametricamente. Procurou-se descrever a forma da curva através da curvatura e da torção. Seguidamente, foram analisados vários métodos de obter novas curvas através de uma curva inicial, nomeadamente a evoluta, involuta, pedal, cissóide e conchóide. No que respeita a uma superfície, a sua forma é descrita através das curvaturas gaussiana e média. Adicionalmente, sobre as curvas contidas em superfícies, a sua forma é descrita através das curvaturas normal, geodésica e principal. As geodésicas são abordadas como sendo curvas contidas numa superfície, apurando a menor distância entre dois pontos na superfície. Saliente-se ainda que, devido à dificuldade e escassez de visualização de tais parametrizações na literatura, pretendeu-se ao longo do trabalho exemplificar graficamente cada caso.
This work was developed with the aim to study the local properties of curves and surfaces, in the euclidean space, through their parametrizations. We described the shape of a curve through its curvature and torsion. Next, we analysed several methods of obtaining new curves from an original curve, namely the evolute, involute, pedal, cissoid and conchoid of a curve. Concerning surfaces, its shape is described by Gaussian and mean curvatures. Additionally, concerning curves contained in surfaces, its shape is described through normal, geodesic and principal curvatures. Geodesics are approached as curves contained in a surface, minimizing the distance between two points on the surface. It should also be pointed out that due to the difficulty and scarcity of visualization of such parametrizations in the literature, it was intended throughout this work to exemplify each case graphically.

Trabalho Final do Mestrado Integrado em Medicina Dentária apresentado à Faculdade de Medicina
INTRODUÇÃO: A estética pessoal assume atualmente um papel importante nos aspetos sociais, emocionais e profissionais. A presença de diastemas nos dentes anteriores pode estar associada a um impacto negativo na estética do sorriso e na fonação. O conhecimento detalhado da morfologia dentária e periodontal associada aos diastemas é fundamental para a elaboração e previsibilidade do eventual plano de tratamento.OBJECTIVO: Caracterização do morfotipo dentário e periodontal associado à presença de diastemas no 2º sextante de jovens adultos, particularmente na correlação da presença de diastemas com a morfologia dos tecidos periodontais.METODOLOGIA: Foram selecionados 22 pacientes, 11 com diastemas (Grupo 1) e 11 sem diastemas nem apinhamento (Grupo 2). Em todos foi realizado um exame oral completo, uma história clinica, um protocolo fotográfico, impressões convencionais e digitais, radiovisiografias e uma tomografia de feixe cónico de modo a determinarem-se alguns dos componentes da morfologia dentária e periodontal destes pacientes. Além das medições analógicas directas e digitais, foram também efetuadas medições com recurso a programas informáticos de integração, análise e coorelação de dados digitais. Foi utilizado o IBM SPSS Statistics 23.0 para executar a análise estatística. A normalidade da distribuição foi avaliada pelo teste de Shapiro-Wilk e as diferenças médias entre os grupos avaliados com o t-test. A correlação de Pearson foi usada para avaliar a correlação entre as variáveis escalares. O nível de significância foi fixado em 0,05.RESULTADOS: No grupo 1, a distância média entre a crista óssea e a papila no diastema mediano foi de 4,18mm± 0,64 e a distância média entre a papila e o zenith é 4,49mm±0,81. No grupo 2, a distância média entre a crista óssea e a papila no diastema mediano foi 3,75mm± 0,38 e a distância média entre a papila e o zenith de 3,97mm±0,63. Em ambos, 90% dos pacientes apresentaram um padrão regular ascendente de distribuição vertical das papilas no 2º sextante. Para estas 3 variáveis analisadas não se verificaram diferenças estatisticamente significativas entre os dois grupos.DISCUSSÃO e CONCLUSÕES: Dentro das limitações deste estudo, pode deduzir-se que, apesar das diferenças nas relações interdentárias nos pacientes com diastemas, o morfotipo periodontal não parece ter alterações relevantes relativamente aos pacientes sem diastemas. A posição e disponibilidade dos tecidos de suporte periodontais na zona dos diastemas não parece ser prejudicada pela existência de espaços interdentários.PALAVRAS-CHAVE: “Diastemas” , “Papila dentária”, “Osso alveolar”, “Dente anterior”, “Interdentária”, “Maturação da sutura média palatina”, “Freio Labial”
INTRODUCTION: Personal aesthetics nowadays play an important role in social, emotional and professional aspects. The presence of diastema in the anterior teeth may be associated with a negative impact on smile aesthetics and phonation. The detailed knowledge of the dental and periodontal morphology associated with diastemas is fundamental for the elaboration and predictability of an eventual treatment plan.OBJECTIVE: Description of the dental and periodontal morphotypes associated with the presence of diastema in the 2nd sextant of young adults, particularly in the correlation of the presence of diastema with periodontal tissue morphology.METODOLOGY: Were selected 22 patients, 11 with diastema (Group 1) and 11 with no diastemas or crowding (Group 2).. All participants were realized a full oral examination and filled a clinical history. Data collection was done using a digital photographic protocol, conventional prints, intra-oral fingerprints, radiovisiographies, and a conical beam tomography to determine some of the components of the dental and periodontal morphology of these patients through various analytical processes. Furthermore to direct and digital-analog measurements in some of the analysis methods, measurements were also made using digital data integration, analysis, and co-data processing software. IBM SPSS Statistics 23.0 was used to perform the statistical analysis. Normality of distribution was assessed with Shapiro-Wilk test and mean differences between groups evaluated with the t-test. Pearson correlation was used to assess correlation between scalar variables. Significance level was set at 0.05.RESULTS: In group 1, the mean distance between the crestal bone and the papilla in the median diastema was 4,18mm±0,64 and the mean distance between the papilla and the zenith was 4,49mm±0,81. In group 2, the mean distance between the bone crest and the papilla in the median diastema was 3,75mm± 0,38 and the mean distance between the papilla and the zenith was 3,97mm±0,63. In both groups, 90% of the patients had the regular ascending pattern of the vertical distribution of the papillae in the 2nd sextant.DISCUSSION and CONCLUSION: Within the limitations of this study, it can be deduced that, despite differences in interdental relationships in patients with diastemas, the periodontal morphotype does not appear to have relevant alterations regarding patients without diastema. The position and availability of periodontal support tissues in diastemas does not appear to be affected by the existence of interdental spaces.KEY – WORDS : “Diastema”, “Dental Papilla”, “Alveolar bone”, “Anterior teeth”, “Interdental”, “Midpalatal suture maturation”, “Labial frenum”

Abstract:
The present dissertation develops an invariant framework for 3D gesture comparison studies. 3D gesture comparison without Lagrangian models is challenging not only because of the lack of prediction provided by physics, but also because of a dual geometry representation, spatial dimensionality and non-linearity associated to 3D-kinematics. In 3D spaces, it is difficult to compare curves without an alignment operator since it is likely that discrete curves are not synchronized and do not share a common point in space. One has to assume that each and every single trajectory in the space is unique. The common answer is to assert the similitude between two or more trajectories as estimating an average distance error from the aligned curves, provided that the alignment operator is found. In order to avoid the alignment problem, the method uses differential geometry for position and orientation curves. Differential geometry not only reduces the spatial dimensionality but also achieves view invariance. However, the nonlinear signatures may be unbounded or singular. Yet, it is shown that pattern recognition between intrinsic signatures using correlations is robust for position and orientation alike. A new mapping for orientation sequences is introduced in order to treat quaternion and Euclidean intrinsic signatures alike. The new mapping projects a 4D-hyper-sphere for orientations onto a 3D-Euclidean volume. The projection uses the quaternion invariant distance to map rotation sequences into 3D-Euclidean curves. However, quaternion spaces are sectional discrete spaces. The significance is that continuous rotation functions can be only approximated for small angles. Rotation sequences with large angle variations can only be interpolated in discrete sections. The current dissertation introduces two multi-scale approaches that improve numerical stability and bound the signal energy content of the intrinsic signatures. The first is a multilevel least squares curve fitting method similar to Haar wavelet. The second is a geodesic distance anisotropic kernel filter. The methodology testing is carried out on 3D-gestures for obstetrics training. The study quantitatively assess the process of skill acquisition and transfer of manipulating obstetric forceps gestures. The results show that the multi-scale correlations with intrinsic signatures track and evaluate gesture differences between experts and trainees.
