As doenças relacionadas com o sobrepeso são consideradas um dos problemas de saúde pública mais grave em todo mundo, associada ao risco de diabetes e doenças cardiovasculares e certos tipos de câncer. O estresse também tem sido mencionado como um problema da sociedade moderna que causa distúrbios emocionais e fisiológicos. Nas últimas décadas foi crescente o número de doenças relacionadas ao estresse, sobrepeso e obesidade, associadas ao aumento do consumo de alimentos energeticamente densos. O objetivo do estudo foi avaliar os efeitos de uma DC associada ao estresse crônico variado (ECV) nos parâmetros bioquímicos, depósitos de gordura corporal e comportamentais. Foram utilizados 40 ratos machos Wistar divididos em quatro grupos: Controle total (C) – Ração padrão sem modelo de estresse; Grupo estresse (E) – ração padrão e estresse; grupo Dieta de cafeteria sem estresse (D) e Grupo Dieta + Estresse (ED). Os animais foram submetidos ao ECV durante 40 dias, em horários e dias alternados. Os parâmetros de ansiedade avaliados pelo teste Labirinto em cruz elevado (Plus Maze) mostraram que a dieta foi capaz de reverter ou amenizar os efeitos do estresse. A atividade locomotora, avaliada pelo teste Campo Aberto (Open Field) não foi alterada pela dieta, nem pelo estresse. A memória avaliada pelo teste Reconhecimento de Objetos não foi alterada, nem pela dieta, nem pelo estresse. Os animais do grupo E obtiveram menor ganho de peso, e a dieta compensou o efeito do estresse em relação ao ganho de peso nos animais que receberam DC e ECV. Houve aumento do peso do fígado e dos tecidos adiposos (subcutâneo e abdominal) dos animais que receberam a DC, porém não submetidos ao ECV. Os níveis séricos de glicose, triglicerídeos, colesterol total, HDL-Colesterol, lipase, foram mensurados, porém não sofreram alterações significativas. / Obesity is defined as an accumulation of fat in the body, caused by a sedentary lifestyle and consumption of high-calorie foods. Diseases related to overweight are considered one of the most serious problems of public health worldwide, associated with risk of diabetes and cardiovascular disease and certain cancers. Stress has also been mentioned as a problem of modern society that causes emotional and physiological disorders. In the last decades has been the increasing number of stress-related, overweight and obesity, associated with increased consumption of energy- dense foods. The object of study to evaluate the effects of a cafeteria diet associated with chronic varied stress (CVS) in biochemical parameters, deposits of body fat and behavioral. Stress Group (S) - standard chow and stress; cafeteria diet group without stress (D) and diet + stress group (SD) standard model without stress control group rats (C): Fourt Wistar rats were divided into four groups used). The animals were submitted to the CVS for 40 days on alternate days and times. The parameters of anxiety assessed by Plus Maze showed that the diet was able to reverse or ameliorate the effects of stress. Locomotors activity, assessed by the Open Field Test was not altered by diet or by stress. The memory assessed by the Object Recognition Test has changed, neither by diet nor by stress. Animals in group E had lower weight gain, diet and offset the effect of stress in relation to weight gain in animals fed cafeteria diet and CVS. There was an increase in liver weight and adipose tissues (subcutaneous and abdominal) of animals that received the cafeteria diet, but not undergoing CVS. Serum glucose, triglycerides, total cholesterol, HDL- Cholesterol, lipase, were measured, but not changed significant.

There are two disciplines that are concerened with the same object of study, narratives, but that rarely exchange insights and ideas, let alone engage in collaborative research. The first is Narrative Theory (NT), an analytical discipline from the humanities that attempts to analyze literary texts and from these instances derive a general understanding of the concept of narrative. The second is Compuatational Story Composition (CSC), a discipline in the domain of Artificial Intelligence that attempts to enable computers to autonomously compose fictional narratives in a way that could be deemed creative. Several reasons can be found for the lack of collaboration, but one of them stands out: The two disciplines follow decidedly different research methodologies at contradistinct levels of abstraction. This makes it hard to conduct NT and CSC research simultaneously, and also means that CSC researchers have a hard time validating whether they use NT concepts correctly, while NT scholars have no use for the outputs created by work in CSC. At the same time, a close exchance between the two disciplines would be desirebale, not only because of the complementary approach to their object of study, but also because comparable interdisciplinary collaborations have proven to be productive in other fields, like for instance linguistics. The present thesis proposes a research methodology called generative modeling designed to address the methodological differences outlined above, and thus allow to conduct simultaneous NT and CSC research. As a proof of concept it performs several cycles of generative modeling, in which it computationally implements concepts and dynamics described in two frameworks from NT, namely Marie-Laure Ryan's possible worlds approach to plot, and Alan Palmer's fictional minds approach to characters. In detail, the first cycle attempts to implement Ryan's possible worlds semantics and the resulting dynamics of plot, but falls short in a way that suggests that the first principles layed out in the theory are not sufficient to capture an example plot, for a number of reasons. The second cycle resolves these hypothesized problems by extending Ryan's plot understanding with affective dynamics based on Palmer's understanding of fictional minds. With plot dynamics completed, the third cycle implements Ryan's concept of tellability, which represents a quantifiable measure of the structural quality of plots. The last cycle implements a Genetic Algorithm based search heuristic that is capable of searching the plot space spanned by the employed formalism for plots high in tellability, which provides additional insights on properties of tellability. The resulting implementation is a in-depth computational representation of plot ingrained into the CSC System InBloom, which is capable of autonomusly composing novel plots and evaluating their quality. The study reported in this thesis demonstrates, how implementing narratological theories as generative models can lead to insights for NT, and how grounding computational representations of narrative in NT can help CSC systems take over creative responsibilities. Thereby, it shows the feasibility and utility of generative modeling.

[pt] A tese desenvolvida no âmbito do Programa de Literatura Cultura e Contemporaneidade resulta da pesquisa, reunião e apresentação de documentos e lembranças sobre uma expedição científica para o Pantanal que ocorreu em 1947. A investigação indaga sobre as dimensões artísticas e científicas da viagem nos contextos geral da expedição e particular de seus participantes, levanta questões sobre métodos para narrar e vislumbrar paisagens e concretiza-se no formato de uma miscelânea verbo-visual. O trabalho se desdobra em dois momentos: o primeiro é voltado para a apresentação da expedição que partiu da então capital federal, Rio de Janeiro, composta por um grupo de estudantes da Universidade do Brasil, liderados pelo geógrafo Hilgard Sternberg, e por outro formado por estudantes do Instituto Rio Branco liderados pelo diplomata e escritor João Guimarães Rosa. O segundo momento volta-se para a metodologia de pesquisa empregada neste trabalho e para os deslocamentos dos estudos técnico-científicos para o âmbito especulativo e artístico, refletindo sobre o trânsito entre as diferentes esferas do conhecimento e experimentando com linguagens verbo-visuais, a partir de fragmentos da expedição e especulações conceituais. O trabalho se constitui na invenção de seu próprio arquivo, transformando vestígios, lembranças e papéis inúteis em documentos. O cerne da pesquisa é o material gerado pelos participantes da expedição, mantido em arquivos públicos e domésticos, como: publicações, lembranças narradas, fotografias, correspondências e cadernos, entre os quais encontramos manuscritos inéditos de Rosa. / [en] The thesis developed within the scope of the Culture and Contemporaneity Literature Program results from the research, gathering and presentation of documents and memories about a scientific expedition to the Pantanal region that took place in 1947. The investigation focuses on the artistic and scientific dimensions of the expedition, by presenting general contexts of the voyage and of its participants; it also raises questions about methods for narrating and envisioning landscapes and takes the form of a verbal-visual miscellany. The work unfolds within two moments: firstly, focuses on the presentation of the expedition that left the former Brazilian Federal District, Rio de Janeiro, composed of a group of students from the University of Brazil, led by the geographer Hilgard Sternberg, and another group of students from the Rio Branco Institute led by the diplomat and writer João Guimarães Rosa. The second moment turns to the research methodology used in the thesis and reflects on the transit from technical-scientific to speculative and artistic scopes, reflecting on different spheres of knowledge and experimenting with verbalvisual languages, working with fragments of the expedition and conceptual speculations. This effort constitutes the invention of an archive of its own, transforming traces, memories and useless papers into documents. The core of the research is the material generated by the expedition s participants, kept in public and domestic archives, such as: publications, narrated memories, photographs, correspondence and notebooks, among which we find unpublished manuscripts by Rosa.

Today, fostering gas-fired power plants is recognised as a significant step towards a low-carbon economy. Gas fired-power plants are favoured over other types of fossil-fuelled power plants due to their various advantages, including lower emissions, flexibility of technology, higher efficiency, short construction times and lower capital investment. The gas turbine is the main machine and the most technologically advanced part of a gas-fired power plant. There have been a limited number of companies in industrialised countries that have developed these sophisticated technologies over the last 50 years. The global market for land-based gas turbines has an oligopolistic structure. The evolution of these technologies has been greatly influenced by countries' government policies, and in particular energy policies. In this light, one question is: to what extent have industrialising countries built their technological capabilities in gas turbines? Consequently, one focus of interest here is the way in which, and the extent to which, industrialising countries have synthesised their indigenous technology development efforts with overseas technology inflows. Countries such as Iran, India and China, which have large and growing domestic electricity markets, are appropriate candidates for research in order to understand the possible technological gaps and associated dynamics between the industrialised and industrialising worlds. To answer these questions, this thesis research deals with Iran's gas turbine industry and, for the first time, systematically examines this industry in the context of a developing country. The study delves deeply into the dynamics of interactions between indigenous technology development and overseas technology inflows. It casts light upon the influences, challenges, and difficulties associated with technological catching-up processes. The framework of the analysis is based on an extensive literature review on technological catch-up, the substitution/complementarity debate, and the gas turbine industry. The framework was operationalized through qualitative interviews as well as supplementary documents. The thesis uses a ‘dynamic approach', and argues that understanding the interaction processes cannot be reduced to examining only the type of relationship between the two technology sources. Instead, far more attention needs to be devoted to analysing the complexity and associated influences on this relationship. The thesis also provides empirical insights into the development of gas turbine capabilities in India and China, the two largest emerging economies. It reveals that a high level of state involvement in developing countries is a prominent feature of the industry. It also demonstrates that the evolution of the industry also in both developed and developing countries is closely interrelated with each country's national energy policies.

Le reportage de fait divers diffusé au Journal Télévisé (JT) est questionné dans cette recherche d’un point de vue « pathémique », c’est-à-dire à travers l’analyse des figures rhétoriques propres à émouvoir le public. Ces figures sont élaborées autour d’une absence d’images explicites, absence paradoxale pour la télévision. Pour analyser la rhétorique émotionnelle construite autour de cette absence iconique — de ce creux —, on a sélectionné une sous-catégorie du fait divers privilégiée par les médias : le drame personnel.La partie I analyse la position du drame personnel vis-à-vis du fait divers ainsi que ses ressorts émotionnels, mettant en évidence l’imaginaire pathémique du fait divers. La recherche se focalise ensuite sur les contextes de production et de présentation des reportages du JT de 20 heures de TF1 (partie II). Le contexte de production renvoie à la part invisible du dispositif, aux différents paramètres symboliques et techniques qui jouent un rôle dans l’élaboration du texte. Le contexte de présentation fonde les cadres instituants de l’information qui guident la lecture du reportage. Tenant compte du sujet raconté et du dispositif chargé d’en rendre compte, la recherche aborde alors l’écriture du drame et les mises en scène télévisuelles à visée dramatisante (partie III). Cette analyse morphologique questionne les enjeux communicationnels et émotionnels d’une forme générique du fait divers au JT. Favorisant l’imagination et l’appropriation du texte, la forme symbolique du drame — composée d’images allusives et banales — vient compenser la singularité des faits exposés. / This research analyses human interest stories on television news from a “pathemic” point of view, namely through the analysis of rhetorical figures aiming to move an audience. These figures are constructed around the absence of explicit images, which is a paradox for the television world. In order to analyze the emotional rhetoric constructed around this iconic absence, we have selected the most popular subcategory in the media, which we have called personal drama.The first part of this research analyzes the position of personal drama in relation to human interest stories and its emotional mainsprings. The second part of the research focuses on the contexts of production and presentation. The production context refers to the invisible part, that is to say, the technical and symbolic parameters which play a central role in the elaboration of the report. Whereas the presentation context acts as a framework which guides the audience in reading the report in a certain way. Considering the event being related and the means to do so, the ultimate aim of the research is to analyse the actual writing of the news story and its dramatization for TV. This morphological analysis questions the communicational and emotional stakes of a generic form of human interest stories on television news. Favouring the imagination and the appropriation of the text, the symbolic form of the drama - composed of allusive and mundane images - compensate for the singular nature of the facts being exposed.

In this study, canola oil has been selected for the test on a diesel engine and its suitability as an alternative fuel has been examined. To decrease the high viscosity of canola oil, the effect of temperature on viscosity has been researched. Then the fuel delivery system has been modified to heat canola oil before injecting the oil into the combustion chamber. Also, ethanol has been tested as an additive by blending with canola oil. An experimental setup has been installed according to standards to carry out tests. The set up has been controlled with a computer to take measurements more precisely and to perform experiment automatically. Experimental investigations have been conducted on a four cylinder, direct injection diesel engine. Full load-variable speed tests have been conducted to evaluate engine performance parameters. In addition 13 mode ESC test cycle has been performed to determine the exhaust emissions. Engine performance and emissions characteristics of canola oil and canola-ethanol blend containing 30% ethanol have been compared with those of baseline diesel fuel. Experimental results show that engine performance decreased for canola oil. Addition of ethanol into canola oil has been noticed to improve performance a little with respect to pure canola oil. Although, maximum performance has been obtained with diesel fuel, minimum specifics energy cost is obtained with canola oil. It has been observed that hydrocarbon (HC) emissions decrease with canola oil, blending ethanol with canola oil increase HC emissions and maximum values are read for diesel fuel. Carbon monoxide (CO) emissions have been observed to be the highest for canola oil but blending ethanol has a decreasing effect on CO emissions. As for particulate matter (PM), use of canola oil has been seen to be more pollutant than diesel but adding ethanol in canola reduces PM emissions significantly.

A computer code is developed using finite volume technique for solving steady twodimensional and axisymmetric compressible Euler and Navier-Stokes equations for internal flows by &ldquo / multi-block&rdquo / technique. For viscous flows, both laminar and turbulent flow properties can be used. Explicit one step second order accurate Lax-Wendroff scheme is used for time integration. Inviscid solutions are verified by comparing the results of test cases of a support project which was supported by ONERA/France for Turkey T-108, named &ldquo / 2-D Internal Flow Applications for Solid Propellant Rocket Motors&rdquo / . For laminar solutions, analytical flat plate solution is used for planar case and theoretical pipe flow solution is used for axisymmetric case for verification. Prandtl turbulent flow analogy is used in a flat plate solution to verify the turbulent viscosity calculation. The test cases solved with single-block code are compared with the ones solved with multi-block technique to verify the multi-block algorithm and good similarity is observed between single-block solutions and multi-block solutions. For the burning simulation of propellant of Solid Propellant Rocket Motors, injecting boundary is used. Finally, a segmented solid propellant rocket motor case is solved to show the multi-block algorithm&rsquo / s flexibility in solving complex geometries.
