Abstract:

Tires are the most influential component of the vehicle as they constitute the only contact between the vehicle and the road and have to generate and transmit forces necessary for the driver to control the vehicle. Hydroplaning is a phenomenon which occurs when a layer of water builds up between the tires of a vehicle and the road surface which leads to loss of traction that prevents the vehicle from responding to control inputs such as steering, braking or acceleration. It has become an extremely important factor in the automotive and tire industry to study the factors affecting vehicle hydroplaning. Nearly 10-20% of road fatalities are caused by lack of traction on wet surfaces. The tire tread pattern, load, inflation pressure, slip and camber angles influence hydroplaning to a great extent. Finite Element Analysis, although computationally expensive, provides an excellent way to study such Fluid Structure Interactions (FSI) between the tire-water-road surfaces. Abaqus FSI CEL approach has been used to study tire traction with various vehicle configurations. The tire force data obtained from the Finite Element simulations is used to develop a full vehicle hydroplaning model by integrating the relevant outputs with the commercially available vehicle dynamics simulation software, CarSim.

Abstract:

In any automotive system, the tires play a very crucial role in defining both the safety and performance of the vehicle. The interaction between the tire and the road surface determines the vehicle's ability to accelerate, decelerate and steer. Having information about this interaction in real-time can be very valuable for the on-board advanced active safety systems to mitigate the risks ahead of time and keep the vehicle stable. The crucial information which can be obtained from the tire includes but are not limited to tire-road friction, tire forces (longitudinal, lateral), normal load, road surface characteristics and tire pressure. This information can be acquired through indirect vehicle dynamics based estimation algorithms or through direct measurements using sensors inside the tire. However, the indirect estimations fail to give an accurate measure of the vehicle state in certain conditions (e.g. side winds, road banking, surface change) and require ABS or VSC activation before the estimation begins. Therefore, to improve the performance of these active stability systems, direct measurement based approaches must be explored. This research expands the applications of Intelligent tire and focuses on using the sensor based measurement approach to develop estimation algorithms relating to tire force measurement. A tri-axial accelerometer is attached to the inner liner of the tire (Intelligent Tire) and two of such tires are placed on an instrumented (MSW, VBox, IMU, Encoders) VW Jetta. Different controlled tests are carried out on the instrumented vehicle and the Intelligent tire signal is analyzed to extract features related to the tire forces and pressure. Due to unavailability of direct force measurements at the wheel, a VW Jetta simulation model is developed in CarSim and the extracted features are validated with a good correlation.

Abstract:

Automotive and Tire companies spend extensive amounts of time and money to tune their products through prototype testing at dedicated test facilities. This is mainly due to the limitations in the simulation capabilities that exist today. With greater competence in simulation, comes more control over designs in the initial stages, which in turn lowers the demand on the expensive stage of tuning. The work presented, aims at taking today's simulation capabilities a step forward by integrating models that are best developed in different software interfaces. An in-plane rigid ring model is used to understand the transient response of tires to various high frequency events such as Anti-Lock Braking and short wavelength road disturbances. A rule based ABS model performs the high frequency braking operation. The tire and ABS models have been created in the Matlab-Simulink environment. The vehicle model has been developed in CarSim. The models developed in Simulink have been integrated with the vehicle model in CarSim, in the form of a design tool that can be used by tire as well as vehicle designers for further tuning of the vehicle functional performances as they relate to in-line braking scenarios. Outdoor validation tests were performed to obtain data from a vehicle that was measured on a suspension parameter measuring machine (SPMM) in order to complement this design tool. The results of the objective tests performed have been discussed and the correlations and variations with respect to the simulation results have been analyzed. Master of Science

Abstract:

The suspension system is one of the most sensitive systems of a vehicle as it affects the dynamic behavior of the vehicle with even minor changes. These systems are designed to carry out multiple tasks such as isolating the vehicle body from the road/tire vibrations as well as achieving desired ride and handling performance levels in both steady state and limit handling conditions. The damping coefficient of the damper plays a crucial role in determining the overall frequency response of the suspension system. Considerable research has been carried out on semi active damper systems as the damping coefficient can be varied without the system requiring significant external power giving them advantages over both passive and fully active suspension systems. Dampers behave as non-linear systems at higher frequencies and hence it has been difficult to develop accurate models for its full range of motion. This study aims to develop a velocity sensitive damper model using artificial neural networks and essentially provide a 'black-box' model which encapsulates the non-linear behavior of the damper. A feed-forward neural network was developed by testing a semi active damper on a shock dynamometer at CenTiRe for multiple frequencies and damping ratios. This data was used for supervised training of the network using MATLAB Neural Network Toolbox. The developed NN model was evaluated for its prediction accuracy. Further, the developed damper model was analyzed for feasibility of use for simulations and controls by integrating it in a Simulink based quarter car model and applying the well-known skyhook control strategy. Finally, effects on ride and handling dynamics were evaluated in Carsim by replacing the default damper model with the proposed model. It was established that this damper modeling technique can be used to help evaluate the behavior of the damper on both component as well as vehicle level without needing to develop a complex physics based model. This can be especially beneficial in the earlier stages of vehicle development. Master of Science

A leader, Yokaanam, that believed to be the reincarnation of John the Baptist, had spiritual guides that helped him to guide the group, he caused polemic in Rio de Janeiro, and after this, peaceful, he received people from Brasilia and neighbourhood to mental and corporal cures. This moviment had been two thesis of doctor degree and one dissertation of mastership s main purpose and was considered by those researches a messianic moviment, but just while the leader was alive. In 1985, with his death, the moviment lost the enchantment, attracting less people than olden days. That s the main purpose of this dissertation. The main purpose is verify if the moviment may be considered messianic after Yokaanam s death. The dissertation try to expose a historic vision of the group and after this it resumes the main thesis and dissertation s ideas, and finally following Weber s concepts about Carism and Routinization, it constructs arguments to answer his own hypothesis. The data colect for the dissertation was done based on the two thesis and the dissertation, on the city journal Our, mountly published, and on local research, sistematic observation, interviews and short questionaries applied. In the end, the dissertation proves, based on the Weber s theory parameters, that the Yokaanam s moviment, today, doesn t seems to be messianic, because some basic characteristics of this moviment, like the founder carism, may be pondered like something that should be latent, his dinamism should be activated if the formal administration elect a new leader who was recognized by all the followers as Yokaanam s reincarnation, and this possibility isn t null, because there s an element of the group that is the kardecist creed of the reincarnation. A Cidade Eclética, distante 10 (dez) quilômetros do município de Santo Antônio do Descoberto (GO), foi construída por um grupo de pessoas que tinha vindo do Rio de Janeiro, em 1956, para viver uma forma de religião que pregava o fim do mundo. Um líder, Yokaanam, que acreditava ser reencarnação de João Batista e tinha guias espirituais que o ajudavam na condução do grupo, tinha suscitado muitas polêmicas no Rio de Janeiro; mais tranqüilo em sua nova sede, recebia moradores tanto de Brasília como das cidades vizinhas, para curas corporais e espirituais. Este movimento tinha sido objeto de estudo de duas teses de doutoramento e uma dissertação de mestrado, e foi considerado pelos autores como sendo um movimento messiâmico enquanto o líder vivia. Em 1985, com a morte do líder, o movimento de Yokaanam parecia ter perdido seu encanto original atraindo menos adeptos. Este é o objeto de estudo desta dissertação. Sua finalidade principal é verificar se o movimento de Yokaanam poderia continuar sendo classificado como messiânico depois da morte do líder. A dissertação procurou dar uma visão histórica do grupo, depois resumiu as principais idéias das duas teses e da dissertação que o estudaram; por fim, a partir do conceito de carisma e rotinização de Weber, construiu seu argumento para responder sua hipótese. A coleta de dados desta dissertação foi feita a partir das duas teses e da dissertação, do jornal da cidade, O Nosso publicado mensalmente e de pesquisa de campo, observação sistemática, entrevistas semi-estruturadas. No final do estudo este trabalho provou que dentro dos parâmetros estabelecidos pela teoria weberiana, o movimento de Yokaanam, não poderia ser classificado hoje como messiânico, porque faltam nele alguns elementos fundamentais destes movimentos, como a presença de um líder tido como messias, a espera do milênio; contudo como o carisma do fundador poderia estar latente na vida do grupo e na esperança de alguns adeptos, nada impediria que em um momento de crise ou conflito maior, entre o grupo em estudo e a sociedade geral, esta liderança surgisse novamente, de sua latência, em um adepto ou uma outra pessoa reconhecida pelo grupo, como reencarnação de Yokaanam.

Abstract:

Le travail présenté dans ce mémoire concerne l'élaboration d'approches de commande tolérante aux défauts (FTC) ainsi que l'estimation simultanée des états du système et de défauts capteurs et actionneurs pour différentes classes de systèmes. Les conditions de synthèse décrites dans ce manuscrit améliorent et permettent de réduire le conservatisme des résultats existants dans la littérature. Dans une première étape, nous nous sommes intéressés à la synthèse de la commande FTC à base d'observateur pour les systèmes T-S descripteurs à retard en présence de défauts actionneurs. Les conditions de synthèse dépendantes de la taille du retard, à la fois de l'observateur et du contrôleur sont résolues en une seule étape. Dans une deuxième étape, nous avons proposé une stratégie d'estimation des défauts et de la commande FTC pour les systèmes descripteurs flous de type T-S en présence simultanée de défauts actionneurs et capteurs ainsi que des perturbations extérieures. La troisième et dernière partie de ce travail concerne la synthèse d'une loi de commande robuste FTC basée sur un observateur adaptatif descripteur pour la dynamique du véhicule. La méthode proposée offre des conditions de LMIs moins restrictives que celles établies dans la littérature. L'approche proposée est validée en simulation sur le logiciel Carsim comme étant une application de la dynamique dérive-lacet-roulis du véhicule en présence de défauts capteurs, actionneurs et de perturbations extérieures This work deals with the development of new technologies of fault tolerant control (FTC), state and sensor/actuator faults estimation for different classes of systems. The algorithm described in this manuscript improve and reduce the conservatism of existing results in the literature. Firstly, we were interested in the synthesis of adaptive observer-based FTC for Takagi-Sugeno (T-S) descriptor systems with time-delay in presence of actuator faults. The analysis and design conditions of observer-based FTC are formulated into a set of delay-dependent linear matrix inequalities (LMIs) which can be solved in a single step. Then, an adaptive observer-based FTC strategy is proposed for both T-S descriptor systems and T-S fuzzy systems subject to simultaneous actuator and sensor faults under external disturbances. The last part of this work concerns the issue of the lateral vehicle and rollover dynamics which is approximated by the T-S fuzzy model under the influence of actuator and sensor faults with external disturbances. Using the cone complementarity linearization algorithm, the proposed method offers less restrictive LMI conditions than those established in the literature. The proposed approach is validated in simulation on the Carsim software as an application of the dynamics of the vehicle in presence of sensor, actuator faults and external disturbances

Abstract:

L'objectif de cette étude est de comprendre le phénomène d'acculturation religieuse et son évolution en Carie, à travers les épiclèses de Zeus ainsi que les cultes et les représentations qui y sont associés. Ce travail privilégie une approche pluridisciplinaire de l'ensemble des données liées aux lieux de culte. Il nous amène à articuler toutes les sources à notre disposition en faisant appel aux diverses disciplines de l'archéologie, ainsi qu'à la philologie, l'épigraphie, la numismatique et l'iconographie, afin de mettre en place un réseau de connaissances associant l'histoire des religions et l'archéologie du culte. Cette approche a pour but de reconstituer le plus objectivement possible la vie religieuse carienne et son paysage religieux. Il s'agit d'étudier l'interaction entre les pratiques et les représentations pour comprendre le lien entre la dimension spatiale des faits religieux et la perception qu'en avaient les anciens. Ce travail de recherche s'interroge également sur les échos entre les cultes et la symbolique des éléments qui les composent. Pour chaque Zeus, il est ainsi nécessaire de déterminer le sens à donner à l'épiclèse et aux représentations qui leur sont associées et de comprendre le contexte cultuel dans lequel ils ont évolué. À travers l'étude de la figure jovienne, dont l'attribut est devenu le symbole du territoire, c'est le fonctionnement du système religieux carien dans son ensemble qui est mis en lumière. Le croisement des diverses données permet enfin d'appréhender le phénomène d’acculturation en Carie. L'objectif est de déterminer les contacts continus et directs que des cultures différentes ont eu et les modifications qu'elles ont entraînées dans les modèles culturels initiaux des divers groupes. Il convient donc de distinguer les permanences et les innovations qui se manifestent au sein de la vie religieuse dans la région. De nombreux éléments préhelléniques sont ainsi notables dans cette région particulièrement conservatrice, permettant parfois d'identifier des traces de continuité ou de réappropriation entre les cultes anatoliens et grecs The objective of this study is to understand the religious acculturation and changes in Caria, through Zeus' epicleses, cults and representations associated with it. This work emphasizes a multidisciplinary approach to all data related to places of worship. It leads us to articulate all the sources available to us through the use of various disciplines of archeology as well as philology, epigraphy, numismatics and iconography, to establish a knowledge network linking religious history and archeology of worship. This approach aims to reconstruct objectively as possible the Carian religious life and religious landscape. This is to study the interaction between practices and representations to understand the relationship between the spatial dimension of religious facts and the perception of them old. This research also questions the echoes between cults and symbolic elements that compose them. Each Zeus, it is thus necessary to determine the meaning of the epiclesis and representations associated with them and understand the cultic context in which they evolved. Through the study of the Jovian figure, whose attribute has become the symbol of the territory, the operation of the Carian religious system as a whole is revealed. The crossing of the various data finally allows us to understand the phenomenon of acculturation in Caria. The aim is to identify ongoing and contacts that different cultures have had and the changes they generated in the original cultural patterns of various groups. It is therefore necessary to distinguish the continuities and innovations that occur in the religious life in the region. Many pre-Hellenic elements are thus particularly notable in this conservative region, sometimes to identify traces of continuity or reappropriation between the Anatolian and Greek cults

Abstract:

L’hydrologie s’est longtemps intéressée uniquement à la branche terrestre du cycle hydrologique. Pourtant, le contenu en vapeur d’eau de l’atmosphère au-dessus du bassin versant peut varier en fonction du transport net de vapeur d’eau par l’atmosphère soit la convergence horizontale du flux de vapeur d’eau (C). Pour de longues périodes de temps et à l’échelle du bassin, C devrait être égale au ruissellement (R) sortant de cette même région. La convergence du flux de vapeur d’eau pourrait constituer une information supplémentaire d’intérêt afin d’améliorer les modèles hydrologiques visant la prévision du débit en rivière. L’objectif général de ce mémoire est d’évaluer quantitativement le cycle hydrologique complet à l’intérieur du modèle régional canadien de climat (MRCC) afin de déterminer le potentiel de la convergence de flux de vapeur d’eau comme variable utilisable en hydrologie appliquée. Le MRCC est un outil d’intérêt en hydrologie puisqu’il permet de modéliser plusieurs processus complexes du cycle hydrologique à l’échelle régionale, en plus de calculer plusieurs composantes du cycle qui sont difficiles à mesurer dans le monde réel. Les résultats indiquent que la convergence du flux de vapeur d’eau est égale au ruissellement à l’échelle temporelle climatique. À l’échelle annuelle, la convergence et le ruissellement demeurent fortement corrélés (r > 0,8). À l’échelle mensuelle et journalière, la corrélation entre les termes diminue vu l’importance de l’eau transitant dans les réservoirs atmosphérique et terrestres. En hiver, la convergence mensuelle des bassins nordiques est approximativement égale à la variation du couvert de neige. Le terme d’erreur du bilan hydrique représente 0 à 10% de C à l’échelle temporelle climatique. Cet ordre d’erreur est nettement inférieur aux termes d’erreur obtenus par des études similaires faites à partir de réanalyses et ce pour des bassins de plus petites superficies. L’erreur dans le bilan hydrique est liée au schéma numérique semi-lagrangien du MRCC et aux interpolations nécessaires au calcul de C. Pourtant cette erreur supposée aléatoire ne diminue pas strictement avec l’augmentation de la superficie du bassin. Ce biais positif,C < R, pourrait être un biais régional engendré par la correction du bilan hydrique intégré à l’intérieur du MRCC. L’augmentation du terme d’erreur aux échelles mensuelles (0 à 30%) et journalières (0 à plus de 100%) est due à un décalage temporel de 6h entre les flux et les variables d’état lors de leur enregistrement par le MRCC.

No. of bitstreams: 1 Silas Gutierrez.pdf: 796305 bytes, checksum: 3899480ce63a2186c61561a627dde2b4 (MD5) Previous issue date: 2015-08-25 Coordenação de Aperfeiçoamento de Pessoal de Nível Superior This work studies the christian jewish myth as a discursive element that gives meaning and value Fernão Cardim letters. Through the studies proposed by Mircea Eliade (2000, 2000a, 2010, 2011, 2012, 2013) and the research conducted by the Bakhtin Circle (1975,1981,1997,2003, 2009), we see how the myth made up by language, creates realities and projects the reader for a supersensible plan. One of the main points of Eliade's studies is to question how the myth or mythical resonances interpose in the lives of human beings in their daily lives, and the religious phenomenon, in the author's opinion, is realized through images and symbols in a mythical context, for a specific type of language because religious symbolism refers to the deeper aspects of life and experience of human being in relation to the world. In our research, we notice that the Colonial Brazil is described mainly as a majestic spatiality; the jesuit creates, as an accomplished painter, a splendid environment and evokes the beauty of nature. Finally, we find that the myth is a way of being of language covering senses regulatory processes; these are related to subjects historically situated in places and different times in relation or not to the same enterprise enunciation. Thence, it follows that the christian jewish myth, seen as an ideological sign, is filled with meaning and purpose, it can be the representation, the ordering and systematization of historical and material relations of a given society Este trabalho estuda o mito judaico cristão como elemento discursivo que confere significado e valor às cartas do jesuíta Fernão Cardim. Por meio dos estudos propostos por Mircea Eliade (2000, 2000a, 2010, 2011, 2012, 2013) e pelas pesquisas realizadas pelo Círculo Bakhtiniano (1975,1981,1997,2003, 2009), observamos como o mito, constituído pela linguagem, cria realidades e projeta o leitor para um plano suprassensível. Um dos pontos principais dos estudos de Eliade é questionar como o mito ou ressonâncias míticas interferem na vida do ser humano em seu cotidiano, sendo que o fenômeno religioso, na opinião do autor, se concretiza por meio de imagens e símbolos em um contexto mítico, por um tipo específico de linguagem, pois o simbolismo religioso refere-se aos aspectos mais profundos da vida e da experiência do ser em relação ao mundo. Em nossa pesquisa, observamos que o Brasil Colônia é figurativizado, sobretudo, como uma espacialidade majestosa; o jesuíta cria, como um exímio pintor, uma ambiência voltada para o grandioso e evoca a beleza da natureza. Por fim, constatamos que o mito é um modo de ser da linguagem que abrange processos de regulação de sentidos; estes estão relacionados a sujeitos historicamente situados em lugares e momentos distintos em relação ou não a um mesmo empreendimento enunciativo. Daí, em-se que o mito judaico cristão, visto como um signo ideológico, é preenchido de sentido e finalidade, podendo ser a representação, a ordenação e a sistematização das relações histórico-materiais de uma dada sociedade

Därefter producerades skisser som visades för en testgrupp, för att samla feedback. Fysiska tester utfördes, innan det slutgiltiga konceptet nåtts: En vagn man kan använda på fyra sätt. Man kan skjuta den framför sig medan man går, eller dra den efter sig, man kan använda den som sparkcykel eller man kan koppla den till en cykel. One of the most threatening issues today is what is happening to our environment. A consi- derable problem for these issues are the emissions. A tremendous contributing factor is the insensible use of fossil fuel driven vehicles. A way of taking a small step i the right direction is to adjust our lifestyle and reduce the use of the car. But also by making more conscious choises in our everyday lives. The aim of this project is to make this a little easier. To help you transport your groceries from for example the store to your home.The process of coming up with what later became the end product, started with interviewing users. Following that, sketches were made and showed to a test group to gather feedback.Physical tests executed, before the final concept was reached: A wagon you cam utilise infour ways. It can be pushed in front of you, while walking. It can be dragged behind, while walking. it can be used as a kick bike and it can be connected to a bicycle.

Observations were made regarding the establishment of colonies on the cladodes of 20 clones of cactus, from a scale ranging from zero to five, zero being the absence of infestation and five the highest. We used the mixed model methodology for obtaining the Best Linear Unbiased Prediction (BLUP) of genotype effects and the process of Restricted Maximum Likelihood (REML) to estimate components of variance and genotypic parameters. The variance components and genotypic parameters were obtained by using the REML process. The selection of the best clones by the REM/BLUP methodology was efficient with high gain selection. High genetic variability was verified among the genetic material evaluated, as shown by the coefficient of genotypic variation (26,73%) and hereditary (72%). These coefficients indicate favorable conditions to clone selection, which can favor considerable genetic advances. The clones “Miuda” and “Orelha de Elefante” were selected and classified as resistants, with relative value above 95%. Explants from the clones of “Orelha de Elefante Mexicana” (Opuntia stricta), “IPA Sertânia” (Nopalea cochenillifera) and “Gigante” (Opuntia fícus-indica), originated from the sequential micro-propagation, were submitted to artificial infestation with Dactylopius opuntiae cochineal nymphs, in order to prove their resistance to this plague. After 150 days of growth, cultivation were removed from the in vitro condition and maintained in environmental conditions. The observations about the fixation of the insects on the explants were made at 7, 14, 21, 28 and 35 days after infestation. Explant samples were immersed on FAA 50 fixator, to produce histological blades. Epiderm and parenchyma areas were sized from the samples. It was found that no nymphs were present on the “Orelha de Elefante Mexicana” and “IPA Sertânia” clones, and that 65% of the explants of the “Gigante” clone were dead by 35 days because of the damage caused by the cochineals. There was no mortality of any explant from the considered resistant material. There were significant differences in epidermal thickness, with the clone “Gigante” having the highest thickness, which contradicts the theory that resistance to cochineal carmine is related to anatomy. Os trabalhos que compõem esta tese têm como objetivo identificar a variabilidade genética entre clones de palma forrageira e comprovar a resistência à cochonilha do carmim em plantas cultivadas in vitro. Foram realizadas observações quanto à fixação de colônias sobre os cladódios de 20 clones de palma forrageira a partir de uma escala de notas, variando de zero a cinco, sendo zero a ausência de infestação e cinco o maior nível de infestação. Utilizou-se a Metodologia de Modelos Mistos para a obtenção da Melhor Predição Linear Não Tendenciosa (BLUP) dos efeitos genotípicos e o processo da Máxima Verossimilhança Restrita (REML) para a estimação dos componentes de variância e dos parâmetros genotípicos. Verificou-se alta variabilidade genética entre o material genético avaliado, conforme depreende-se das estimativas do coeficiente de variação genotípica (26,73%) e da herdabilidade (72%), que indicam condições favoráveis à seleção, as quais podem conduzir a avanços genéticos consideráveis. Os clones Miúda e Orelha de Elefante Africana foram classificados como resistentes com valor relativo superior a 95%. Na segunda parte do trabalho, plantas dos clones Orelha de Elefante Mexicana, IPA Sertânia e Gigante, provenientes da micropropagação, foram submetidos à infestação artificial com ninfas da cochonilha Dactylopius opuntiae para comprovação da resistência a essa praga, após cultivo in vitro. Aos sete, 14, 21, 28 e 35 dias após a infestação, realizaram-se observações quanto à fixação dos insetos sobre as plantas. Amostras das plantas foram colocadas em fixador FAA 50 para confecção de lâminas histológicas. Mediu-se a área da epiderme e do parênquima. Verificou-se que nenhuma ninfa se estabeleceu sobre os clones Orelha de Elefante Mexicana e IPA Sertânia e que 65% das plantas do clone Gigante estavam mortas aos 35 dias em decorrência dos danos causados pelas cochonilhas. Não houve mortalidade de nenhuma das plantas dos materiais considerados resistentes. Foi verificada diferença significativa para espessura da epiderme e o clone Gigante apresentou maior espessura. Dessa forma não se comprova a teoria de que a resistência à cochonilha do carmim está relacionada ao aspecto anatômico de espessura da epiderme.

Abstract:

"Sem resumo feito pelo autor"; - Os sistemas salobros litorais, estuários e lagunas, despertaram desde sempre o interesse da Humanidade, constituindo vias de navegação ou locais preferenciais para o desenvolvimento urbano e industrial, e são, por outro lado, utilizados como zonas de pesca e de cultivo de peixes, bivalves e crustáceos. Consideram-se os estuários como uma importante fonte de alimento para os consumidores primários que se localizam, na sua grande maioria, no sedimento fazendo parte do povoamento bentónico (McLUSKY, 1981). Entre os consumidores primários existentes nos sistemas salobros litorais sobressaiam os moluscos bivalves que desempenham um importante papel na estruturação da teia trófica do ecossistema e que constituem, sob o ponto de vista humano, um valioso recurso natural. O estudo da bioecologia destes moluscos é de grande importância pois, deste modo, não só se tem acesso ao modo como o seu ciclo biológico se processa como se reconhecem interdependências entre as espécies e o meio. Estes dados contribuem, assim, para o aprofundamento do conhecimento sobre as espécies e, ao dar indicações sobre a sua inserção no ecossistema, permitem o entendimento de processos mais globais. O objectivo do presente trabalho é o estudo da biologia e de aspectos da ecologia de duas espécies de lamelibrânquios do género Cardium (berbigão). Este estudo integra-se num estudo colectivo sobre os sistemas lagunares e "estuarino-lagunares" da Costa Sudoeste de Portugal Continental que tem vindo a ser efectuado, desde 1984, por elementos do Departamento de Ecologia da Universidade de Évora e do Laboratório Marítimo da Guia da Faculdade de Ciências de Lisboa, nomeadamente sobre as Lagoas de Santo André, Melides e Sancha (COSTA et al ., 1985; FONSECA, et al ., 1987; BERNARDO et al ., 1987; CANCELA DA FONSECA, 1989; CANCELA DA FONSECA et al ., 1989; BERNARDO, 1990) e os sistemas "estuarino-lagunares" de Odeceixe, Aljezur e Carrapateira (MAGALHÃES et al ., 1987; COSTA et al ., 1988; CRISTO et al ., 1989; COSTA et al ., 1990; DUARTE et al ., 1990). Este estudo cent ra-se em Cardium edule e Cardium glaucum cujo reconhecimento como duas espécies válidas só foi efectuado em 1958 por HOPNERPETERSEN. Regista-se, no entanto, ainda um certo cepticismo por parte de alguns investigadores relativamente a este reconhecimento. Os trabalhos desenvolvidos nas últimas décadas que abordam a fisiologia e ecologia destas espécies confirmam a sua existência como duas espécies distintas (RYGG, 1970; BOYDEN, 197la; JELNES et al., 1971; BROCK, 1978; 1979; 1980a; 1980b; 1987; ANSELL, 1981). As dificuldades sentidas na distinção dos exemplares provenientes do Sudoeste de Portugal levaram à adopção de metodologias bioquímicas. Estas permitiram estabelecer um conjunto de características morfológicas que identificam as duas espécies para todo o litoral de Portugal. O estudo bio-ecológico realizou-se nos sistemas estuarino-lagunares de Odeceixe e de Aljezur. Estes sistemas de pequenas dimensões onde ocorre, com alguma periodicidade, uma alternância entre uma fase lagunar e uma fase estuarina têm uma dimensão que facilita a compreensão dos processos dinâmicos e ecológicos. Este estudo reporta-se a um período em fase estuarina. Os estudos, em número apreciável, sobre Cardium edule dizem respeito a quase toda a sua área de distribuição geográfica: Norte da Europa (BAGGERMAN, 1953; HOPNER-PETERSON, 1958; VAN URK, 1973; BROCK, 1979; MOLLER & ROSENBERG, 1991) França (DUCROTOY et al .,1987; DESPREZ et al .,1987; GUILLOU et a] ., 1990), Espanha (MEJUTO, 1984a, 1984b; SAAVEDRA-MARTIN, 1984; NAVARRO et al ., 1989), Portugal (VILELA, 1947; GORDO, 1982; MOREIRA, 1988). Os dados existentes para Cardium glaucum são relativos a populações estuarinas do Norte da Europa (HOPNER-PETERSON, 1958; TULKKI, 1961; RUSSELL, 1971; BOYDEN & RUSSELL, 1972; BARNES, 1973; BROCK, 1979; WOLOWICZ, 1984) e a populações lagunares mais ou menos isoladas do mar (IVELL, 1979a, 1979b; WOLOWICZ, 1987a; ZAOUALI, 1975a, 1975b, 1975c). Justifica-se assim o estudo de Cardium edule e Cardium glaucum nestes ecossistemas do Sudoeste de Portugal por se localizarem na zona intermédia da sua área de distribuição geográfica. O facto de, nestes sistemas, as populações das duas espécies se inserirem no mesmo tipo de habitat estuarino possibilita que se proceda a comparações da sua bio-ecologia. Face ao carácter heterogéneo deste trabalho optou-se por apresentar em cada capítulo as metodologias adoptadas, especificando-as unicamente na primeira vez que são utilizadas ao longo do trabalho.

Para a obtenção do corante foram analisados vários fatores: pH, tempo e concentração de reagentes. Procurou-se através da variação dos fatores se obter um corante de coloração visualmente igual ao comercial e com alto teor de pigmento. O corante foi obtido sob as formas de pó e líquido. O teor médio de ácido carmínico obtido no carmim foi de 57,35%, bem acima do mínimo recomendado, 6,74% de umidade e 21,18% de proteína. Para isto foi utilizado água como solvente na proporção 120 ml/g de amostra, extração a temperatura de ebulição por 15 minutos, precipitação da laca em pH 6, a temperatura de ebulição por 30 minutos, tendo como reagentes sulfato de alumínio e acetato de cálcio. O rendimento em massa de ácido carmínico foi de aproximadamente 48%. A estabilidade do corante líquido foi estudada em função dos efeitos da luz (1.200 lux), temperatura (25°C a 100°C), pH (2,3 a 7,8) e matrix alimentícia (leite integral). O efeito da luz, temperatura, pH e matrix alimentícia sobre 'a estabilidade do carmim foi estudado pela variação de absorbância dos três primeiros e pela variação de cor no último. A partir da variação de absorbância foi possível determinar os valores da constante de velocidade da reação e o tempo de meia vida em cada sistema além das perdas de ácido carmínico. A temperatura foi o agente mais destrutivo da cor, sendo a luz e o pH praticamente inertes. O efeito da matrix alimentícia não influiu na estabilidade do carmim. O presente trabalho teve como objetivo obter um corante carmim de mesma cor, composição e estabilidade que um corante padrão obtido no mercado Abstract: In this work was obtained a natural colorant, of red colour, from an insect called cochineal (Dacty/opius coccus Costa).

Abstract:

Type 2 diabetes is the fastest growing health threat to the UK, with prevalence rising 60% over the past decade. Those with Type 2 diabetes carry twice the risk of developing cardiovascular disease, a condition which claims the lives of the majority of adults in the UK. A significant proportion of cardio-metabolic disease could be prevented through improvements in lifestyle. Technological advancements, motorised transport and an increase in desk based work, have paved the way for physical inactivity to be norm in modern society. Clinical and government strategies to target unhealthy lifestyles are currently lacking. The aim of this thesis was to explore lifestyle related behaviours in cardio-metabolic disease, with a view to improving clinical care. A UK population based study (n=502,664) demonstrates that those with cardio-metabolic disease are characterised by low physical activity, sedentary behaviour and poor sleep. Combining all three behaviours exposes individuals to greater cardio-metabolic risk. A cross-sectional study (n=57) indicates that there are significant cardiac abnormalities in those with metabolic disease in the absence of overt heart disease. Finally, a randomised controlled trial (n=28) provides evidence that exercise can be used as a therapeutic strategy to improve cardiac structure and function in adults with Type 2 diabetes, and thereby moderate cardiac risk in this patient group. This thesis delivers two clear messages; 1) lifestyle behaviours remain significant unaddressed risk factors and 2) physical activity and exercise strategies should be used as therapies to reduce risk and improve cardio-metabolic health. Looking ahead, the results from the this study highlight the need for lifestyle behaviours to be part of the prevention and management strategies for cardio-metabolic health, and support the NHS’s 5 year plan to encourage healthier lifestyles as a priority.

Abstract:

L’époque hellénistique est le moment où les villes d’Ionie et de Carie changent peu à peu d’aspect. Dans chaque ville ou presque, quantité de monuments publics nouveaux façonnent progressivement un paysage urbain inédit qui se présente comme un miroir de la cité qui l’a créé. C’est cette transformation sans précédent des centres urbains durant l’époque hellénistique que cette thèse se propose d’étudier, en portant attention aux villes d’Ionie et de Carie dans toute leur diversité. Elle cherche à dégager le sens des changements dans deux régions à l’hellénisation ancienne et fortement urbanisées, caractérisées par des interactions entre cités et rois hellénistiques. Cette étude propose des pistes pour mieux comprendre les sociétés civiques au travers d’un lieu de vie : la ville. L’approche privilégie ce que la ville a de plus remarquable, ses édifices publics. Dans une première partie consacrée aux fortifications urbaines, aux lieux qui abritent les activités politiques, et aux espaces de la vie culturelle au sens large, les monuments publics sont évoqués en tant qu’espaces de la vie civique, et l’on s’interroge sur les raisons de la construction de tant de bâtiments nouveaux. Dans un second temps, une étude plus transversale de l’espace urbain décrit comment se met en place à cette époque un cadre de vie véritablement urbain, avec un paysage, des aménagements et une organisation de l’espace bien spécifique. La troisième partie consacrée aux thématiques économiques montre comment la prospérité des cités se traduit dans la pierre : la construction de bâtiments pour abriter les activités économiques témoigne autant du souci des cités de développer et d’encadrer ces activités que de la richesse de la vie économique des poleis. Ce dynamisme contribue aussi à expliquer une activité de construction soutenue, rendue possible par l’existence de ressources abondantes et variées à la disposition des cités. La réflexion porte pour finir sur la dimension politique et sociale des transformations de l’espace urbain. Cette dernière partie se place dans une perspective historique plus large, celle de l’évolution de la cité hellénistique The Hellenistic period is the time when the aspect of the cities of Ionia and Caria is changing gradually. In almost each city, an amount of new public buildings progressively shaping a new urban landscape that looks like a mirror of the city that created it. It is this unprecedented transformation of urban centers during the Hellenistic period that this thesis studies, with attention to the cities of Ionia and Caria in all their diversity. We aim at making sense of the changes in these two regions, which experienced hellenisation and urbanisation early ; they are also characterized by interactions between cities and Hellenistic kings. This study suggests ways of understanding civic societies through the city. We are looking at t the most remarkable features of the city : its public buildings . In the first part devoted to urban fortifications, buildings housing political activities , and areas of cultural life , public monuments are mentioned as spaces of civic life , and we search for the reason why many new buildings were built. Then, the study describes how urban space becomes a place of truly urban life, with a landscape, facilities and a specific spatial organization. In a third section, we show how the cities’ economic prosperity is reflected in stone buildings – some of them housing economic activities – reflects the will of cities to develop and oversee economic activities and the wealth of the poleis. This also helps explain a sustained construction activity made possible by the existence of abundant and varied resources available to cities. Finally, the reflection deals with political and social aspects of the evolution of urban space. This last part is placed in a broader historical perspective, that of the evolution of the Hellenistic city

The intakes of dry matter, organic matter, neutral detergent fiber and digestible energy were, on average, 3.4% PC, 2.9% CP, 0.72% CP and 2.8 Mcal / day, respectively, and were not influenced by the variety of the palm. The digestibility of DM and OM were higher in diets composed by “Orelha de elefante Mexicana” “IPA Sertania”, compared to a diet composed by “Miuda” variety. The digestibility of NDF and energy were not influenced by the variety of palm and were, on average, 46.3% and 72.4%. The experimental diets did not influence weight gain or carcass yield, which averaged 89.0 g / day and 52.4%, respectively. The animals were given an average of 62.2 ml of water / day for two consecutive days every 3.3 days. The Mexicana varieties of “Orelha de elefante” (Opuntia stricta), “IPA-Sertânia” (Nopalea cochenillifera) and “IPA-F21” (Nopalea cochenillifera) can be fed to sheep without compromising its performance. Objetivou-se com este trabalho determinar o valor nutricional das variedades de palma forrageira resistente à Cochonilha do carmim (Dactylopius opuntiae Cockerell): Orelha de Elefante Mexicana (Opuntia stricta), IPA-Sertânia (Nopalea cochenillifera), Miúda (Nopalea cochenillifera Salm-Dyck), IPA-F 21 (Nopalea cochenillifera). Foram utilizados 24 ovinos SPRD, com peso vivo inicial médio de 21,0±0,5 kg, distribuídos em delineamento experimental de blocos casualizados, com quatro tratamentos e seis repetições. As dietas experimentais foram compostas por palma forrageira, farelo de soja (Glycine max (L.)), uréia agropecuária e sal mineral. Os consumos de matéria seca, matéria orgânica, fibra em detergente neutro e energia digestível foram, em média, 3,4%PC; 2,9%PC; 0,72%PC e 2,8Mcal/dia, respectivamente, e não foram influenciados pela variedade da palma. Os coeficientes de digestibilidade da MS e da MO foram mais altos nas dietas compostas por Orelha-de-Elefante-Mexicana e IPA-Sertânia, em comparação a dieta composta pela variedade Miúda. Os coeficientes de digestibilidade da FDN e da energia não foram influenciados pela variedade de palma e foram, em média, 46,3% e 72,4%. As dietas experimentais não influenciaram o ganho de peso nem o rendimento de carcaça, que foram em média 89,0 g/dia e 52,4%, respectivamente. Os animais ingeriram em média 62,2 mL de água/dia, por dois dias consecutivos, e mantiveram intervalo de 3,3 dias sem consumir agua voluntariamente. As variedades Orelha de Elefante Mexicana (Opuntia stricta), IPA-Sertânia (Nopalea cochenillifera) e IPA-F21 (Nopalea cochenillifera) e Miúda (Nopalea cochenillifera Salm-Dyck) podem ser utilizadas na alimentação de ovinos sem comprometer seu desempenho.

In the study conducted with sheep were evaluated the effects of the “Miúda”, “IPA Sertânia”, “Orelha de Elefante Mexicana and “Orelha de Elefante Africana” cactus pear genotypes on intake, digestibility, ruminal parameters, nitrogen balance and microbial protein synthesis and compared with the effects of the “Gigante” cactus pear. Five male castrated sheep (53.2 ± 4.8 kg BW) with rumen cannula were used. The experimental diets contained one genotype of cactus pear (440 g/kg DM), alfalfa hay (585 g/kg DM) and mineral mixture (15 g/kg DM). The diet containing “Gigante” cactus pear (PGG) was the control treatment. There were no differences in the intakes of dry matter (DM), organic matter (OM) and metabolizable energy (ME) for PGG diet and others. The diet containing “Orelha de Elefante Mexicana” cactus pear (PMX) provided higher crude protein (CP) intake. The PGG diet showed lower CP digestibility than diet containing “IPA Sertânia” cactus pear (PST) and PMX diet and lower FDN digestibility than the diet containing “Miúda” cactus pear (PMD) and the PST and PMX diets. The control diet promoted lower ruminal pH than the diet containing “Orelha de Elefante Africana” cactus pear (PAF), lower ruminal ammonia concentration than PST and PMX diets and lower molar proportion of acetate than the diets PMD, PMX and PAF. In the study conducted with lactating dairy cows the same cactus pear genotypes were evaluated, except “Orelha de Elefante Africana” cactus pear. Eight Girolando cows were used, distributed into two 4 x 4 Latin squares. The experimental treatments consisted of a complete feed containing one genotype of cactus pear (440 g/kg DM), sorghum silage (380 g/kg DM), soybean meal (150 g/kg DM ), urea (8 g/kg DM) and mineral mixture (17 g/kg DM). The diet PMD provided greater intakes DM, OM and total digestible nutrients (TDN) than the control diet. Greater CP intake was observed when the PMD and PST diets were provided; a lower non-fibrous carbohydrate (NFC) intake was observed when the PST and PMX diets were provided. The control diet showed lower DM and OM digestibility than PMD and PST and lower CP and NDF digestibility than PMD, PST and PMX. Lower milk, protein, lactose and total solids yield were observed when PST and PMX were supplied. The supply of PMX promoted lower fat-corrected milk yield and milk protein content. The PMX diet provided a greater ratio of unsaturated to saturated fatty acids and a greater proportion of desirable fatty acids. The control diet showed microbial protein synthesis similar to other diets. For sheep and according to the evaluated parameters, it is concluded that the “Miúda”, “IPA Sertânia”, “Orelha de Elefante Mexicana” and “Orelha de Elefante Africana” cactus pear can replace “Gigante” cactus pear. Considering data of intake and performance, the ‘Miúda’ cactus pear is the carmine cochineal resistant genotype that is most suitable to be supplied in diets for lactating cows. Dois experimentos foram conduzidos com o objetivo de avaliar genótipos de palma forrageira resistentes à cochonilha do carmim em dietas para ruminantes. No experimento realizado com ovinos foram avaliados os efeitos dos genótipos Miúda, IPA Sertânia, Orelha de Elefante Mexicana e Orelha de Elefante Africana sobre consumo, digestibilidade, parâmetros ruminais, balanço de nitrogênio e síntese de proteína microbiana, comparados aos efeitos da palma Gigante. Foram utilizados cinco ovinos machos, castrados, providos de cânula ruminal, com peso corporal médio de 53,2 ± 4,8 kg. Os tratamentos experimentais continham um genótipo de palma forrageira (400 g/kg de MS), feno de alfafa (585 g/kg de MS) e mistura mineral (15 g/kg de MS). A dieta contendo palma Gigante (PGG) foi considerada o tratamento controle. Não foram observados efeitos dos genótipos resistentes à cochonilha do carmim sobre os consumos de matéria seca (MS), matéria orgânica (MO), carboidratos totais (CHT), fibra em detergente neutro (FDN), carboidratos não fibrosos (CNF) e energia metabolizável (EM), porém a dieta contendo palma Orelha de Elefante Mexicana (PMX) proporcionou maior consumo de PB e a dieta contendo palma Orelha de Elefante Africana (PAF) menor consumo de EE que a dieta controle. A dieta controle apresentou menor digestibilidade da PB do que a dieta contendo palma IPA Sertânia (PST) e do que a dieta PMX, assim como menor digestibilidade da FDN que a dieta contendo palma Miúda (PMD) e que as dietas PST e PMX. A dieta controle promoveu menor pH ruminal que a dieta PAF, menor concentração de N-NH3 ruminal que as dietas PST e PMX e menor proporção molar de acetato do que as dietas PMD, PMX e PAF. No experimento realizado com vacas leiteiras os mesmos genótipos foram avaliados, exceto a palma Orelha de Elefante Africana, sendo os efeitos sobre consumo, digestibilidade, produção e composição do leite e síntese de proteína microbiana comparados aos da palma Gigante. Foram utilizadas oito vacas da raça Girolando, distribuídas em dois quadrados latinos 4 x 4. Os tratamentos experimentais consistiram de ração completa contendo um genótipo de palma forrageira (443 g/kg MS), silagem de sorgo (380 g/kg MS), farelo de soja (150 g/kg MS), uréia (8 g/kg MS) e mistura mineral (19 g/kg MS). A dieta PMD proporcionou maiores consumos de MS, MO e NDT que a dieta controle. Observou-se maior consumo de PB quando fornecidas as dietas PMD e PST e menor consumo de CNF quando fornecidas as dietas PST e PMX. A dieta controle apresentou menor digestibilidade da MS e MO que as dietas PMD e PST e menor digestibilidade da PB e FDN que PMD, PST e PMX. Foram observadas menores produções de leite, proteína, lactose e sólidos totais quando fornecidas as dietas PST e PMX e menores produção de leite corrigido para gordura e teor de proteína no leite quando fornecida PMX. A dieta PMX proporcionou maior relação entre ácidos graxos insaturados e ácidos graxos saturados e maior proporção de ácidos graxos desejáveis no leite. Não houve efeito das dietas contendo genótipos resistentes à cochonilha do carmim sobre a síntese de proteína microbiana. Para ovinos e de acordo com os parâmetros avaliados, conclui-se que a palma Miúda, a palma IPA Sertânia, a palma Orelha de Elefante Mexicana e a palma Orelha de Elefante Africana podem substituir a palma Gigante. No caso de vacas em lactação, considerando os dados de desempenho e consumo, a palma Miúda é o genótipo resistente à cochonilha do carmim mais indicado para substituir a palma Gigante.

Abstract:

Mi tesis doctoral lleva por título: El carisma político en la Teoría Sociológica. La investigación se ha centrado en definir el concepto de carisma político a través de distintos autores de la Teoría Social. El autor más relevante es, sin duda, Max Weber quien abordó en toda su complejidad la dimensión del concepto de carisma. Weber incluso considera que el carisma es capaz de cambiar la historia. Los autores previos que trataron el tema son Platón, Maquiavelo, Carlyle y Nietzsche y Durkheim quien desarrolló el concepto de "efervescencia colectiva". Hay que destacar que si bien estos autores construyen el concepto y se preguntan por el fenómeno carismático, no lo mencionan explícitamente. Por otra parte, Le Bon y Freud analizaron el concepto desde el punto de vista de la psicología de las masas. Después de Weber deben ser destacadas las aportaciones de Edward Shils quien incidió en la importancia del concepto de carisma propiamente dicho. Shils destacó su carácter central, además de ser un elemento generador de orden en las sociedades. Asimismo, observó su capacidad de legitimar un poder político. Otros autores modernos que han trabajado sobre el fenómeno y las relaciones carismáticas son Luciano Cavalli, Salvador Giner, David Aberbach, Ronald M. Glassman, Kyösti Pekonen, William H. Swatos, Charles Lindholm, Peter Kivisto y David Tàbara, entre otros. Cavalli ha enfatizado la necesidad de un liderazgo personal en las democracias occidentales, así como, la relación de confianza y responsabilidad que se establece entre el líder y el electorado. Giner enfatiza la metaracionalidad del carisma y su manufactura en las sociedades modernas. Mi hipótesis central es que a pesar que el carisma sea irracional, siempre tiene un cierto grado de racionalidad, aspecto que puede ser explicado a través de cada cultura, a través de cada uno de los seguidores del líder. En la dimensión carismática encontramos otros aspectos muy relacionados con el carisma político, tales como el carisma de la religión, el liderazgo político, el populismo, la identidad y los movimientos sociales. La gran revolución del carisma tuvo lugar durante los años sesenta debido a la generalización del uso de la televisión. Ésta ha transformado la morfología del carisma y la imagen pública de los políticos. Así, los medios de comunicación se han convertido en esenciales para ganar las elecciones. Por otra parte, el concepto de carisma ha sido trivializado por la prensa. Otro campo de investigación de gran interés es el carisma de género. A pesar que podemos definir el carisma como una característica perenne de todas las sociedades y a pesar que no podamos concebir las relaciones sociales sin su presencia, éste tiene un lado oscuro. Puede convertirse en peligroso al servicio de demagogos e ideologías como el fascismo. Así, un exceso de fascinación por el carisma puede ir en contra de la cultura política y del espíritu crítico de las democracias. No obstante, el carisma es un atributo necesario para todo tipo de líderes políticos democráticos, sin el cual los políticos no pueden triunfar electoralmente. Considero el carisma peligroso y simplista, puede incluso sustituir la cultura política, sin embargo, no podemos ignorarlo. Las muestras de afecto, las emociones, son presentes en las manifestaciones políticas y refuerzan las distintas adhesiones a los líderes y a sus partidos. TITLE: POLITICAL CHARISMA IN SOCIOLOGICAL THEORY AUTHOR: BLANCA DEUSDAD University of Barcelona. Economics Faculty. Department of Sociological Theory. My Doctoral dissertation bears the title: Political Charisma in Sociological Theory ("El carisma político en la Teoría Sociológica"). I have focused my research on defining the concept of charisma through the different authors of Social Theory. The most relevant author is Max Weber who explains all the dimension of the concept of charisma. Weber even considers that charisma is able to change history. The previous authors that deal with the term are Plato, Machiavelli, Carlyle and Nietzsche, Durkheim who has developed the concept of collective effervescence. Even though these authors build the concept, they do not mention it explicitly. Moreover, Le Bon and Freud analyze the concept from the point of view of Psychology of the masses and Ortega y Gasset was concerned with the need of good government. After Weber the theories of Edward Shils must be underlined. He stresses the importance of the concept of charisma, especially as a central, order-creating and order-disclosing element. Furthermore, he emphasizes the charisma that contains the legitimacy of political power. In addition, modern authors as Luciano Cavalli, Salvador Giner, David Aberbach, Ronald M. Glassman, Kyösti Pekonen, William H. Swatos, Charles Lindholm, Peter Kivisto and David Tàbara, among others, study charisma and its demonstrations in modern societies. Cavalli underlines the need of a personal leadership in governments and its relation of confidence and responsibility with the electorate. Giner emphasizes the metarationality of charisma and its manufacture in Modern Societies. My central hypothesis is that even though charisma is irrational, it always has a certain degree of rationality, which can be explained by means of each culture, by means of every leader's follower. In the charismatic dimension there are other aspects very closely related to political charisma, but apart of charisma of religion, such as political leadership, populism, identity and social movements The greatest revolution took place in the sixties due to the increasing use of television. TV has transformed charisma's morphology and the politicians' public image in the mass media has become essential to win elections. Furthermore, the term has been trivialised by the press. It is also important to develop the research of charisma of gender. Even if charisma is a perennial feature of all societies and we cannot leave without it, it is a double-edged sword. It may become dangerous; it can support some ideologies such as fascism. An excess of fascination can go against political culture and the critical spirit of the democracies. Charisma is an attribute necessary to all kind of political leaders in the democracies, without which leaders could not, became successful in political elections. We consider charisma dangerous and simplistic, it can even substitute the political culture yet we cannot ignore it. Emotions, affections are present in political demonstrations and reinforce political adherences.

Abstract:

The thesis presents a detailed analysis of the effects of one-sided access z-direction reinforcement, ‘tufting’, on the morphology and mechanical performance of the resulting MVR-444 epoxy matrix/carbon fibre fabric composites. The dry fabric architectures used are pseudo-UD, twill woven fabric and non-crimped fabric (NCF). They are tufted with a range of commercial tufting threads, using KSL KL150 tufting head mounted on a 6-axis robot arm. The main focus is on the use of a twisted carbon fibre thread, at areal tufting densities of 0.5% and 2%. The composite plates are prepared via Resin-Transfer- Moulding (RTM) route, making it possible to control the plate thicknesses. The morphological features characteristic of tufted, cured composites are described and categorised. The global and local fibre volume fractions are measured and simple models proposed that connect local increase with local fibre deviation and presence of resin rich surface loop layers. It is shown that the balance of in-plane and out-of-plane properties in tufted composites is highly dependent on the tufting parameters, but also on the fabric architecture, with the NCF option seeming the most attractive. Overall, the stiffness of tufted materials is not affected and the drop in in-plane strength of any realistic geometry combinations is below 20%. ‘Thread-less’ tufting experiments prove that the drop is not caused by fibre breakage from the passage of the needle alone. Digital image correlation (DIC) techniques is used to map out the strain field distributions during mechanical testing, increasing the accuracy of crack tip location in Mode II delamination cracking studies and confirming the mode mixity changes during deformation of tufted structures. Single-tuft experiments provide the experimental data that are required for the development and validation of analytical models. A finite element unit cell model is developed to predict in-plane elastic and failure behaviour of tufted UD and NCF composites incorporating the critical meso-structural features of fibre deviation and increased fibre volume fraction. The thesis also contains an overview of the tufting technology and some detailed information on recent manufacturing developments that were required to obtain the controlled quality specimens used in the study. A demonstration structural element was produced, in the form of a tufted omega-stiffener. A standard pull-off test demonstrates the superior load carrying and energy absorbing capacity of this strengthened structure. Details of robot programming, additional single tuft bridging results, test fixture design, derivation of the analytical bridging model and additional publications are given in appendices to the main body of the thesis.

Abstract:

This thesis explores the challenge of using deep neural networks to classify traits incars through sound recognition. These traits could include type of engine, model, or manufacturer of the car. The problem was approached by creating three different neural networks and evaluating their performance in classifying sounds of three different cars. The top scoring neural network achieved an accuracy of 61 percent, which is far from reaching the standard accuracy of modern speech recognition systems. The results do, however, show that there are some tendencies to the data that neural networks can learn. If the methods and networks presented in this report are further built upon, a greater classification performance may be achieved.

Abstract:

L’étude des mécanismes physiologiques au cours d’une plongée subaquatique est essentielle à la compréhension des accidents qui lui sont associés. Le plongeur subit de nombreuses contraintes issues du milieu dans lequel il évolue. L’objectif de notre travail a été d’appréhender les modifications du contrôle neurovégétatif qui régule le système cardiovasculaire induites par les contraintes rencontrées en plongée telles que l’immersion, l’exposition au froid, l’ambiance hyperbare, l’exposition hyperoxique et l’exercice physique. Nos investigations ont été réalisées chez le plongeur militaire professionnel (Plongeur Démineur et Nageur de Combats) et chez le volontaire sain novice en plongée. L’étude du système neurovégétatif était basée sur l’analyse de la variabilité de l’intervalle RR (contrôle cardiaque) et de la variabilité de la pression artérielle (contrôle vasculaire). Des mesures ultrasonores (échographie bidimensionnelle et Doppler) et des mesures de tonométrie d’applanation ont complété nos données hémodynamiques. Une accélération de la fréquence cardiaque a été observée en début d’immersion totale. Une adaptation au mode ventilatoire (SCUBA) et un réchauffement des territoires cutanés pourraient être impliqués dans ce phénomène transitoire. A la sortie des 6 heures d’immersion, une déshydratation sévère est présente. Son caractère iso-osmotique est responsable d’une faible stimulation de la soif, et par conséquent la correction du déficit hydrique est longue (supérieur à 16 heures). L’hyperoxique normobare aigue ralentit la fréquence cardiaque par stimulation de l’activité parasympathique et induit une vasoconstriction périphérique qui est régulée par des facteurs locaux (diminution de l’activité orthosympathique). Après l’exposition hyperoxique, la normalisation de la fréquence cardiaque est rapide tandis que les résistances vasculaires systémiques sont au contraire persistantes ce qui évoque des effets de l’hyperoxie dissociés de la périphérie (vaisseaux, contrôle local) et du central (coeur, système neurovégétatif et contractilité du myocarde). Une plongée unique a un retentissement important sur le système cardio-vasculaire. L’hypothèse de perturbations à long terme étant soulevée il était important de rechercher des signes d’altération chez le plongeur militaire professionnel. L’entraînement spécifique à la plongée réalisé par l’élève Plongeur Démineur entraîne une augmentation de la compliance artérielle qui est probablement secondaire à l’entraînement physique en endurance complémentaire. Par ailleurs, les expositions immergées répétées sont à l’origine d’une acclimatation au froid des plongeurs. Le nageur de combats, lui, réalise des plongées oxygène. Une altération à long terme de la vasomotricité pouvait être redoutée. Or, l’étude comparative avec un groupe contrôle apparié n’a pas mis en évidence de signes d’altérations vasculaires. En conclusion, la plongée génère d’importantes modifications du système cardiovasculaire et de son contrôle neurovégétatif. Néanmoins, des expositions répétées chez le militaire bénéficiant d’un entraînement physique régulier ne s’accompagnent pas d’altérations à long terme During a dive, subjects undergo environmental stressors such as immersion, cold exposure, increased ambient pressure, hyperoxia and physical exercise. All these stressors may be responsible for changes in cardiovascular system and consequently modified autonomic nervous control. The aim of this work was to assess physiological changes induced by diving to better understand injuries reported during this activity. Investigations were performed in professional divers (military mine clearance divers and elite military oxygen divers). Autonomic nervous activity was assessed by power spectral density of heart rate variability (cardiac control) and blood pressure variability (vasomotor control). Hemodynamic changes were assessed by 2-Dimensional and Doppler echocardiography. Arterial wall compliance was estimated by pulse wave analysis. Heart rate increased during the two first hours of total thermoneutral water immersion without significant changes in power spectral density of heart rate variability. This increase might be attributed to artificial ventilation (SCUBA) and peripheral circulatory changes. Dehydration induced by 6-hours of water immersion involved plasmatic, interstitial and intracellular compartments. Post-water immersion dehydration was iso-osmotic i. E. The thirst sensation was weak. Consequently, marked hemodynamic changes had not returned to baseline 16-hours after water immersion. In healthy young adults, normobaric hyperoxia didn’t affect blood pressure but induced an increase in systemic vascular resistances. Sympathetic nervous activity to vasomotor control was decreased during hyperoxia and these changes persisted 10 minutes after the return to ambient air. Heart rate returned to baseline (inferior to 5 minutes) before stoke volume and cardiac output correction (30 minutes). The decrease in heart rate was attributed to an increase in parasympathetic nervous activity. On the other hand, an increase in sympathetic activity was observed during 30 minutes after the end of hyperoxic exposure. These results were in accordance with two distinct phenomena of hyperoxia, one peripheral (local control) and other one central (cardiac autonomic nervous control and myocardial alterations). Several studies have described cardiovascular changes-induced by an acute dive. Given that cardiovascular long-term effects of repeated dives have been suggested, we carried out cardiovascular investigations on professional divers. Military mine clearance divers performed intensive diving training. An increase in arterial compliance was observed and has been attributed to the physical endurance training experienced by military divers. Moreover, some peripheral vascular acclimatization to cold was developed. Military oxygen divers were exposed to daily hyperoxia. We hypothesized long term vascular alterations in this population. However, comparative study with a well-matched control group showed no sign of vascular alteration. In summary, diving activity-induced important cardiovascular changes. Autonomic nervous activity was also modified. However, no long-term cardiovascular alteration was found in well trained military divers

Abstract:

Le suivi cardio-respiratoire des nourrissons à risque ou issus de fratrie à mort subite constitue encore un enjeu d'importance. A ce titre, il est nécessaire de poursuivre l’étude de ces techniques suivis cardio-respiratoires car le taux trop important de fausses alarmes conduit, dans le meilleur des cas, les familles à ne plus utiliser ces appareils. Dans le cadre de travail, nous avons commencé par une large revue du syndrome de mort subite du nourrisson de manière à dégager ce qui en fait ses spécificités et, par là-même, les spécificités du système cardio-respiratoire chez le nourrisson ; nous montrons ainsi que le nœud central de ce syndrome réside dans la maturation du système cardio-respiratoire et la capacité du nourrisson à s'éveiller dans des situations critiques. Nous avons ensuite testé un système de capteurs acoustiques par l’intermédiaire d’un double système d'acquisition mis en place de manière à ne pas modifier les pratiques de routine et à valider la technique proposée. Nous avons constaté que les systèmes quotidiennement utilisés dans les services pédiatriques n'offrent pas nécessairement la fiabilité espérée. Malheureusement les capteurs acoustiques ne se révèlent plutôt moins fiables. Les électrocardiogrammes enregistrés sont ensuite utilisés pour construire des tachogrammes (séries temporelles des intervalles RR) permettant l'étude des dynamiques cardiaques de nourrissons ayant fait des malaises ou des bronchiolites et suivis à ce titre au service de pédiatrie du CHU de Rouen. Ceci constitue une base de données assez rare, au moins si l'on en juge le peu d'articles publiés sur la dynamique cardiaque de nourrissons Cardiorespiratory monitoring of newborns presenting some alerts remains an important task. Due to that, it is still required to investigate the reliability of these techniques due to the large rate of false alarms: in the best case, newborn’s family does no longer use the monitor. In this work, we started by a large review of the infant sudden death syndrome in order to exhibit its specificity and, by this way, the specificities of the cardio-respiratory system in newborns. We thus showed that the main aspect of this system is its lack of maturation and infant’s ability to wake up in acute situation. We then tested a setup based on acoustic sensors to monitor the cardio-respiratory system of infants. Unfortunately, we were not able to obtain a system with a high reliability. Moreover, the classical monitors also present some weakness. The electrocardiograms recorded during this protocol were used to build tachograms (times series of RR intervals) allowing to investigate the cardiac dynamics of infants with cardio-respiratory alerts and hospitalized at the pediatric care unit at Rouen Hospital. This is a quite rare database, at least from the very small number of papers published with such data

Abstract:

Doutoramento em Engenharia Electrotécnica Esta dissertação aborda o tema da Tomografia Axial Computorizada com especial enfoque na reconstrução da imagem, ou seja, nos métodos matemáticos que, dado um conjunto de amostras da intensidade de radiação X transmitida, recolhidas segundo uma geometria de irradiação específica, permitem obter o mapa da distribuição tri-dimensional (3D) do coeficiente de atenuação linear no interior do objecto. Em termos mais formais, dado que, do ponto de vista matemático, o processo de aquisição dos dados corresponde à amostragem da transformada de Radon da função que descreve a distribuição do coeficiente de atenuação no volume sob estudo, estamos interessados nos métodos matemáticos que permitem calcular a transformada inversa de Radon a partir de conjuntos suficientemente densos de amostras. O ambiente de simulação utilizado, desenvolvido de forma a permitir a aquisição de amostras da transformada de Radon de um modelo digital dinâmico do tórax humano (4D MCAT) segundo qualquer uma das geometrias de amostragem actualmente em uso nos equipamentos modernos, permitiu a implementação e avaliação de novos métodos de reconstrução. Nomeadamente, são propostos novos métodos de reconstrução rápida baseados na teoria de Fourier e no cálculo da transformada de Fourier a partir de amostras não equiespaçadas, quer para geometria de aquisição paralela quer divergente, e é abordado o tema da reconstrução dinâmica sendo exploradas várias técnicas de reconstrução que permitem reduzir os efeitos do movimento nos estudos cardio-torácicos. Os estudos realizados permitem demonstrar que o desempenho dos métodos de Fourier propostos é equivalente, no que respeita à qualidade de imagem, ao desempenho do método de Retroprojecção Filtrada, habitualmente utilizado nos equipamentos comerciais mas a custos computacionais significativamente mais baixos. This thesis addresses the theme of Computed Tomography, with special emphasis on tomographic reconstruction techniques, this means, the mathematical methods which, given a set of samples of transmitted radiation intensity, acquired with a specific sampling geometry, provide a threedimensional (3D) map of linear attenuation coefficient of the given object. Since, from a mathematical point of view, the acquisition process corresponds to the sampling of the Radon transform of the function describing the spatial distribution of attenuation coefficient in the volume under study, we are interested in methods and algorithms leading to diverse numerical implementations of the inverse Radon transform from sufficiently dense sets of samples. The developed simulation environment, capable to perform virtual acquisition of Radon transform’s samples of a digital anatomical model, in our case the dynamical digital model of human thorax (4D MCAT), through any of the sampling geometries currently used in commercial equipments, enabled the implementation and evaluation of new reconstruction methods. We propose new methods for fast reconstruction based on Fourier theory and on the calculation of Fourier transform for non-equispaced samples, both for parallel and for divergent acquisition geometries, and we deal with the topic of dynamic reconstruction, by exploring some reconstruction techniques capable of minimizing movement artifacts in cardio-thoracic images. The studies performed demonstrated that the performance of the proposed Fourier methods regarding image quality is similar to the Filtered Backprojection method, traditionally used in commercial equipments but at significantly lower computational costs.

Abstract:

L'étude des mécanismes physiologiques au cours d'une plongée subaquatique estessentielle à la compréhension des accidents qui lui sont associées. Le plongeur subit denombreuses contraintes issues du milieu dans lequel il évolue. Parmi ces contraintes, qui leplus souvent se combinent, nous pouvons citer l'immersion, l'exposition au froid,l'hyperbarie, les variations des conditions d'oxygénation (hypoxie, hyperoxie) et l'exercicephysique. L'objectif de notre travail a été d'apprécier les modifications de la fonction cardiovasculaireet de son contrôle neuro-végétatif induites par ces contraintes rencontrées enplongée chez des sujets sains, novices en plongée, et également chez des chasseurs sousmarins. L'étude de la circulation artérielle et de la fonction endothéliale était basée surl'échographie (bi-dimensionnelle et Doppler). Des mesures de tonométrie d'applanation etautres mesures ultrasonores ont complété nos données hémodynamiques. L'étude du systèmeneurovégétatif était basée sur l'analyse de la variabilité de l'intervalle RR (contrôle cardiaque)et de la variabilité de la pression artérielle (contrôle vasculaire). Après un exercice aigu de pédalage de 45 minutes à haute intensité, l'augmentationpost-exercice du flux sanguin et de la vasodilatation endothéliale a été réduite aux musclesparticipant activement à l'exercice comparé aux muscles non actifs. Pour expliquer cesdifférences, la contribution de l'inflammation locale et du stress oxydatif élevé présents dansles muscles actifs de l'exercice pourrait avoir un rôle During a dive, subjects undergo environmental stressors such as immersion, coldexposure, hypoxia, hyperoxia and physical exercise. All these stressors may be responsible forchanges in cardiovascular system and consequently modified autonomic nervous control. Theaim of this work was to assess physiological changes induced by diving to better understandinjuries reported during this activity. Investigations were performed in healthy men and inspearfishermen. Hemodynamic changes and endothelial function were assessed by 2-Dimensional and Doppler echocardiography. Arterial wall compliance was estimated by pulsewave analysis. Autonomic nervous activity was assessed by power spectral density of heartrate variability (cardiac control) and blood pressure variability (vasomotor control). After an acute cycling exercise of 45 minutes in high intensity, the increase postexerciseof the blood flow and the endothéliale vasodilatation was reduced to musclesparticipating actively in the exercise compared with no active muscles. To explain thesedifferences, the contribution of the local inflammation and the important oxydative stress inthe active muscles of the exercise could have a role. Thermoneutral head-out water immersion induce hemodynamic and arterial changes. At rest, we observed a brachial arterial vasodilatation. This might be attributed to endothelialrequest inferred by increase of the peripheral arterial debit flow. Endothelial reactivity did notseem to be modified. With cycling exercise in low intensity,hemodynamic differencesobserved disappear. At rest, normobaric hyperoxia didn't affect blood pressure but induced an increase insystemic vascular resistances

Abstract:

Time domains of the hypoxic ventilatory response (HVR) are time dependent changes in ventilation that take place without changes in metabolic rate or arterial PCO2. Time domains of the HVR have been described in mammals along with their underlying mechanisms. Each time domain reflects a different change in the various steps in the control of breathing. Peripheral chemoreceptors are necessary for the expression of all time domains in mammals and changes in their sensitivity (reflected in release of different neurotransmitters) are involved in several of the time domains. I demonstrated that neuroepithelial cells (NECs) in the gills of trout (Oncorhynchus mykiss) and goldfish (Carassius auratus) contain serotonin, but not acetylcholine or catecholamines. Acetylcholine was expressed in bipolar neurons in the filaments, and nerve bundles near the efferent filament arteries (eFA) in trout and goldfish and evidence suggests that they may play a key role in producing the HVR in these species. In bowfin (Amia calva), I found five different types of serotonin containing NECs in the gills (identified as Type I to V). Three of these cell types (I - III) had the potential to be oxygen chemoreceptors. Time domains were evident in the HVR of bowfin during moderate exposure to hypoxia but only when they did not have access to air. In these fish, all three putative chemoreceptors increased in size during sustained hypoxia. The NECs found in the basal lamina near the eFA responded exclusively to hypoxaemia (by changing cell size and shape) while the other two NEC types responded to aquatic hypoxia as well. Exposure to sustained hypoxia also caused changes within the oxygen transport cascade: the gill ventilatory sensitivity to hypoxia increased and the Hb-O₂ binding affinity decreased suggesting that acclimation to hypoxia in Amia elicits changes that both increase oxygen uptake and enhance oxygen delivery to the tissues. This thesis focused primarily on a time domain in bowfin similar to the ventilatory acclimatization to hypoxia seen in mammals and highlights the importance of changes in both the peripheral oxygen chemoreceptors as well as in the oxygen transport cascade in establishing this time dependent change.
