The market strategies alternatives of an e-business start-up in Brazil

The e-business market is one of the fastest growing markets in Brazil, with e-business sales accounting for BRL 14.8 billion in 2010 and a growth of 40% per year (+1000% over the past 7 years). Sales-event clubs and collective bargaining websites are one of the most dynamic segments of the e-business market: the number of new players is increasing rapidly, with over 1200 collective bargaining websites currently operating in Brazil. In that context, growth and differentiation seem to be two key success factors for Coquelux. According to webshopper (23rd Edition, e-bit), growth can be achieved by targeting middle and low-income consumers from class C, who represent 50% of the total e-commerce sales. But Coquelux, which is specialized in desire and luxury brands, has built its reputation and competitive advantage through its “exclusivity”, by targeting wealthier consumers from classes A and B who are attracted by its fashionable and high-end positioning. The evolution (growth?) of this market and the development of its competition naturally raise a strategic question for Coquelux’s managers: can Coquelux grow and still maintain its competitive advantage? Should it grow by expanding its consumer base to class C? If so, how? Consumers from classes A, B or C must be targeted through the same online communication channels. Recent studies from the ABEP/ABIPEME emphasized the importance of social networks as a tool for converting new clients and gaining their loyalty, regardless of their social class. However, high-income and low-income e-consumers do not have the same consumption habits, do not respond to the same type of marketing strategies, and most importantly, do not share the same values. Thus, it seems difficult to expand Coquelux’s consumer base to class C without changing its marketing strategies and altering its image Three options were identified for Coquelux: reinforcing its leadership on the luxury segment and focusing on a small niche market (1), which would threaten its survival in the long run; completely changing its strategy and competing for a mass market through commercial brands (2), which requires major financial investments that managers don’t have access to; or finding an intermediary solution (3). This thesis’ recommendation for the third option consists in focusing on premium brands (rather than luxury) in order to increase sales volume (Coquelux’s most profitable sales happened with local desire brands) with products that appeal to class B but also attract the emerging class C which is looking for brand recognition. It could thus implement a slow entry strategy towards the mass market without damaging its main competitive advantage.

Avaliação da eficiência energética em um sítio industrial utilizando análise pinch com heurísticas e técnicas de projeto

Este trabalho envolve a avaliação da eficiência energética em um sítio industrial, que contém três plantas de produção de polietilenos, utilizando conceitos da análise pinch associados com heurísticas e técnicas de projetos. Na primeira etapa do trabalho, foi realizada uma análise preliminar, na qual foram verificadas as possibilidades de melhorias nas condições de operação das unidades. Com esta avaliação, obteve-se uma economia de 500kg/h de vapor de baixa pressão com a simples alteração na sua pressão de fornecimento para uma das unidades. Na seqüência, com base no conhecimento dos processos e na avaliação das curvas compostas das unidades, verificou-se o potencial de integração energética das plantas individualmente, selecionando-se uma unidade (Planta 3) para ser reprojetada. Para esta unidade foram eliminadas do problema as correntes utilizadas em condições esporádicas, as correntes fora da faixa de integração e, por fim, aquelas cuja integração seria demasiadamente complexa. Após estas simplificações, verificou-se o Ponto de Estrangulamento Energético da unidade, os trocadores que empregam utilidades de uma forma inapropriada, o consumo atual e o mínimo de vapor. Com base nestas informações foram verificadas as modificações estruturais na rede de trocadores de calor da Unidade 3 que resultariam em uma unidade energeticamente mais eficiente. Para isto, utilizou-se o programa Aspen Pinch (da Aspen Tech) que gerou uma lista com vinte possibilidades de adição de novos trocadores. Considerando-se somente as modificações com economia superior a 200kW e as restrições de segurança, layout e controle, apenas duas oportunidades foram detalhadas. A primeira delas, foi o aproveitamento do vapor de flash resultante da expansão do condensado de média pressão da unidade. A segunda oportunidade envolveu a adição de um novo trocador, que foi projetado utilizando-se o programa Bjac conjuntamente com o Aspen Plus. Ambas as oportunidades foram avaliadas economicamente, apresentando Taxas Interna de Retorno muito superiores à Taxa mínima de atratividade de 15% considerada neste trabalho.

Facebook3d

INTRODUCTION With the advent of Web 2.0, social networking websites like Facebook, MySpace and LinkedIn have become hugely popular. According to (Nilsen, 2009), social networking websites have global1 figures of almost 250 millions unique users among the top five2, with the time people spend on those networks increasing 63% between 2007 and 2008. Facebook alone saw a massive growth of 566% in number of minutes in the same period of time. Furthermore their appeal is clear, they enable users to easily form persistent networks of friends with whom they can interact and share content. Users then use those networks to keep in touch with their current friends and to reconnect with old friends. However, online social network services have rapidly evolved into highly complex systems which contain a large amount of personally salient information derived from large networks of friends. Since that information varies from simple links to music, photos and videos, users not only have to deal with the huge amount of data generated by them and their friends but also with the fact that it‟s composed of many different media forms. Users are presented with increasing challenges, especially as the number of friends on Facebook rises. An example of a problem is when a user performs a simple task like finding a specific friend in a group of 100 or more friends. In that case he would most likely have to go through several pages and make several clicks till he finds the one he is looking for. Another example is a user with more than 100 friends in which his friends make a status update or another action per day, resulting in 10 updates per hour to keep up. That is plausible, especially since the change in direction of Facebook to rival with Twitter, by encouraging users to update their status as they do on Twitter. As a result, to better present the web of information connected to a user the use of better visualizations is essential. The visualizations used nowadays on social networking sites haven‟t gone through major changes during their lifetimes. They have added more functionality and gave more tools to their users, but still the core of their visualization hasn‟t changed. The information is still presented in a flat way in lists/groups of text and images which can‟t show the extra connections pieces of information. Those extra connections can give new meaning and insights to the user, allowing him to more easily see if that content is important to him and the information related to it. However showing extra connections of information but still allowing the user to easily navigate through it and get the needed information with a quick glance is difficult. The use of color coding, clusters and shapes becomes then essential to attain that objective. But taking into consideration the advances in computer hardware in the last decade and the software platforms available today, there is the opportunity to take advantage of 3D. That opportunity comes in because we are at a phase were the hardware and the software available is ready for the use of 3D in the web. With the use of the extra dimension brought by 3D, visualizations can be constructed to show the content and its related information to the user at the same screen and in a clear way. Also it would allow a great deal of interactivity. Another opportunity to create better information‟s visualization presents itself in the form of the open APIs, specifically the ones made available by the social networking sites. Those APIs allow any developers to create their own applications or sites taking advantage of the huge amount of information there is on those networks. Specifically to this case, they open the door for the creation of new social network visualizations. Nevertheless, the third dimension is by itself not enough to create a better interface for a social networking website, there are some challenges to overcome. One of those challenges is to make the user understand what the system is doing during the interaction with the user. Even though that is important in 2D visualizations, it becomes essential in 3D due to the extra dimension. To overcome that challenge it‟s necessary the use of the principles of animations defined by the artists at Walt Disney Studios (Johnston, et al., 1995). By applying those principles in the development of the interface, the actions of the system in response to the user inputs became clear and understandable. Furthermore, a user study needs to be performed so the users‟ main goals and motivations, while navigating the social network, are revealed. Their goals and motivations are important in the construction of an interface that reflects the user expectations for the interface, but also helps in the development of appropriate metaphors. Those metaphors have an important role in the interface, because if correctly chosen they help the user understand the elements of the interface instead of making him memorize it. The last challenge is the use of 3D visualization on the web, since there have been several attempts to bring 3D into it, mainly with the various versions of VRML which were destined to failure due to the hardware limitations at the time. However, in the last couple of years there has been a movement to make the necessary tools to finally allow developers to use 3D in a useful way, using X3D or OpenGL but especially flash. This thesis argues that there is a need for a better social network visualization that shows all the dimensions of the information connected to the user and that allows him to move through it. But there are several characteristics the new visualization has to possess in order for it to present a real gain in usability to Facebook‟s users. The first quality is to have the friends at the core of its design, and the second to make use of the metaphor of circles of friends to separate users in groups taking into consideration the order of friendship. To achieve that several methods have to be used, from the use of 3D to get an extra dimension for presenting relevant information, to the use of direct manipulation to make the interface comprehensible, predictable and controllable. Moreover animation has to be use to make all the action on the screen perceptible to the user. Additionally, with the opportunity given by the 3D enabled hardware, the flash platform, through the use of the flash engine Papervision3D and the Facebook platform, all is in place to make the visualization possible. But even though it‟s all in place, there are challenges to overcome like making the system actions in 3D understandable to the user and creating correct metaphors that would allow the user to understand the information and options available to him. This thesis document is divided in six chapters, with Chapter 2 reviewing the literature relevant to the work described in this thesis. In Chapter 3 the design stage that resulted in the application presented in this thesis is described. In Chapter 4, the development stage, describing the architecture and the components that compose the application. In Chapter 5 the usability test process is explained and the results obtained through it are presented and analyzed. To finish, Chapter 6 presents the conclusions that were arrived in this thesis.

inVídeo: uma aplicação de vídeo interactivo sobre a Internet

A utilização de vídeo e áudio sobre a Internet tem ganho nos últimos anos um interesse crescente. Na verdade, o interesse não é recente, mas os limites tecnológicos de variadíssimas ordens impediam o desenvolvimento e a utilização alargada de aplicações com media ricos. Os avanços nas tecnologias relacionadas com, por exemplo, a compressão, as redes e as ferramentas multimédia possibilitaram o desenvolvimento e o funcionamento, de uma forma alargada, de sistemas multimédia. O trabalho apresentado nesta dissertação descreve a especificação e a implementação de um sistema de formação à distância, designado inVídeo, que utiliza o vídeo como elemento central. O sistema tem como objectivo proporcionar formação por intermédio de uma aplicação que permite a visualização paralela de um vídeo com imagens ou animações, acompanhada com outros dados, como texto e acesso a ficheiros que podem ser descarregados. O enquadramento para esta aplicação surgiu das necessidades de formação contínua de um centro hospitalar, todavia a aplicação foi desenvolvida para poder ser utilizada noutras instituições. A especificação passou pela descrição do problema e sua modelação utilizando um método para o desenvolvimento de aplicações interactivas, o WISDOM. A implementação descreve o sistema desenvolvido, a justificação das opções tecnológicas e os resultados de um inquérito feito aos utilizadores do sistema. O desenvolvimento do sistema levou ao estudo e, em alguns casos, à utilização de um conjunto de tecnologias distintas. Os estudos iniciais abordaram as tecnologias que possibilitam a utilização do vídeo sobre a Internet e algumas das suas condicionantes. Seguiram-se a composição, sincronização e interactividade multimédia, e por fim o uso de metadados para conteúdos educacionais. A resposta dada pelos utilizadores durante a utilização do sistema foi bastante satisfatória e revelou um grande interesse no uso do vídeo sobre a Internet. A construção de aplicações para Internet utilizando media exigentes deixou de ser a tarefa complexa que era há alguns anos, isto devido aos avanços tecnológicos. Todavia o desenvolvimento ainda necessita de muita ponderação e do enquadramento de muitos factores relacionados com a codificação dos media e com a heterogeneidade das redes, dos utilizadores e dos equipamentos.

Impacto do realismo e qualidade gráfica no desenvolvimento de jogos móveis

O mundo dos jogos é extremamente vasto e muito apreciado pela maior parte dos jovens e também adultos. Os computadores, as consolas e agora também os telemóveis acabam por se tornar os maiores companheiros das pessoas no que ao entretenimento diz respeito. No entanto, existem algumas lacunas a nível de jogos para telemóvel e pretendeu-se então criar um jogo, que se baseia num acontecimento real muito apreciado por toda uma população e que permitiu explorar a ferramenta Flash, que tem vindo a retirar protagonismo ao Java, por se revelar uma ferramenta mais simples de utilizar. No início apenas era usada para simples animações, mas entretanto passou a ser utilizada para criar aplicações para diversas plataformas e dispositivos. Neste momento, o Flash já chegou aos dispositivos móveis e são cada vez mais aqueles que suportam estas aplicações, que podem variar dos simples utilitários aos jogos ou ainda a complexos sistemas.

Framework para o desenvolvimento e integração de aplicações de realidade virtual, realidade aumentada e multimédia

Os ambientes virtuais têm sido cada vez mais utilizados nas mais diferentes áreas, quer na medicina, engenharia civil ou até mesmo em áreas terapêuticas. Devido à sua emergente utilização foi estabelecido em parceria com o Museu da Baleia, através de várias reuniões, que seria viável a modelação de cenários virtuais, onde se desenvolvessem animações, com o intuito de que representassem o ciclo de vida das baleias cachalotes. Esta escolha foi efectuada de forma a envolver várias temáticas relacionadas com as baleias cachalotes, desde a migração, os problemas relacionados com o lixo no fundo do mar, etc. De seguida, foi construída uma Framework para incorporação destas animações (vídeos) e realização de actividades utilizando diferentes tipos de médias, Realidade Virtual e Realidade Aumentada, tornando desta forma as actividades mais interactivas, estimulantes e atractivas. Para a execução destas etapas do projecto foi decidido utilizar a ferramenta 3ds Max para a modelação dos objectos que iriam compor os cenários virtuais, bem como a sua animação. Para a implementação da Framework foi decidido utilizar o Adobe Flash visto ser uma ferramenta que permite a incorporação de diferentes tipos de médias, de Realidade Virtual, Realidade Aumentada e possibilita a construção de uma interface simples e atractiva. Esta Framework foi desenvolvida para que no futuro seja possível ser modificada, isto é, para que seja capaz de efectuar a incorporação de outros tipos de conteúdos, assim como a edição dos que já estão implementados.

Estudo da qualidade do ar interior em infantários da Região Autónoma da Madeira

Presentemente as pessoas passam cerca de 90% da sua vida no interior de edifícios, onde a poluição atinge níveis superiores aos registados no exterior. Os infantários são espaços onde a qualidade do ar interior (QAI) deverá ser alvo de maior preocupação, visto ser o local onde as crianças passam uma fase importante do seu desenvolvimento físico-motor. São vários os poluentes que podem comprometer a saúde humana, de entre os quais se destacam os poluentes biológicos, os químicos, e os físico-químicos. O presente trabalho teve como objectivo analisar a QAI em onze infantários da Ilha da Madeira durante as quatro estações do ano. Para o estudo foi levado em consideração a dispersão geográfica e a envolvente rural e urbana. Complementarmente, foi efectuado um estudo aprofundado dos compostos orgânicos voláteis (COVs) em dois dos infantários, com o emprego de amostragem activa e passiva. Nos infantários em análise, verificou-se a existência de um sério problema de renovação do ar no interior das salas, reflectido nas elevadas concentrações de CO2 e bactérias encontradas durante a monitorização dos espaços. As concentrações de fungos raramente excederam o valor máximo de referência (VMR), sendo o Penicillium spp. e o Cladosporium sp., as espécies mais comuns encontradas. Contudo foram detectadas algumas espécies consideradas perigosas para a saúde humana, como o Aspergillus niger e o A. versicolor. Relativamente aos restantes parâmetros (CO, O3, HCHO, NO2, NO, SO2, H2S, PM10, T e HR), na sua generalidade apresentaram concentrações inferiores aos respectivos VMR: excepção para o HCHO que em 40% das análises revelou valores acima do seu VMR, bem como a T e HR, que apresentaram valores fora das respectivas escalas de referência. Não foram encontradas diferenças significativas na QAI entre os onze infantários no que diz respeito à sua localização geográfica e envolvente. No entanto, em alguns parâmetros foram observadas variações sazonais. O estudo dos perfis de COVs revelou que o tipo de amostragem a empregar deve ter em consideração o objectivo da recolha: se for necessária a obtenção de dados como um flash instantâneo, a utilização da amostragem activa é aconselhada, se forem requeridos dados médios de um determinado período de tempo, o emprego da amostragem passiva será a melhor escolha.

Utilização do éster de soja como biolubrificante

The lubricants found in the market are of mineral or synthetic origin and harm to humans and the environment, mainly due to their improper discard. Therefore industries are seeking to develop products that cause less environmental impact, so to decrease mainly, operator aggression the Cutting Fluids became an emulsion of oil / water or water / oil. However, the emulsion was not considered the most suitable solution for environmental question, therefore the search for biodegradable lubricants and which no are toxic continues and so vegetable oils are seen, again, as a basis for the production of lubricants. The biggest problem with these oils is their oxidative instability that is intensified when working at high temperatures. The process transesterification decreases the oxidation, however changes some physical and chemical properties. Therefore soybean oil after the transesterification process was subjected to tests of density, dynamic viscosity, kinematic viscosity which is calculated from two parameters mentioned, flash point and acidity. Besides the physico-chemical test the soybean oil was subjected to a dynamic test in a tribometer adapted from a table vise, whose induced wear was the adhesive and ultimately was used as cutting fluid in a process of turning in two different materials, steel 1045 and cast iron. This latter test presented results below the mineral cutting fluid which it was compared in all tests, already in other experiments the result was satisfactory and other experiments not, so that chemical additives can be added to the oil analyzed to try equate all parameters and so formulate a biolubrificante not toxic to apply in machining processes of metalworking industry

Estudo das propriedades físico-químicas do biodiesel e suas influências na deterioração dos elastômeros aplicados no sistema de injeção dos motores diesel

The biodiesel use has become important due to its renewable character and to reduce environmental impacts during the fuel burning. Theses benefit will be valid if the fuel shows good performance, chemistry stability and compatibility with engines. Biodiesel is a good fuel to diesel engines due to its lubricity. Then, the aimed of this study was to verify the physicalchemistry properties of biodiesel and their correlations with possible elastomers damage after biodiesel be used as fuel in an injection system. The methodology was divided in three steps: biodiesels synthesis by transesterification of three vegetable oil (soybean, palm and sunflower) and their physical-chemistry characterization (viscosity, oxidative stability, flash point, acidity, humidity and density); pressurized test of compatibility between elastomers (NBR and VITON) and biodiesel, and the last one, analyze of biodiesels lubricity by tribological test ball-plan( HFRR). Also, the effect of mixture of biodiesel and diesel in different concentrations was evaluated. The results showed that VITON showed better compatibility with all biodiesel blends in relation to NBR, however when VITON had contact with sunflower biodiesel and its blends the swelling degree suffer higher influences due to biodiesel humidity. For others biodiesels and theirs blends, this elastomer kept its mechanical properties constant. The better tribological performance was observed for blends with high biodiesel concentration, lower friction coefficient was obtained when palm biodiesel was used. The main mechanisms observed during the HFRR tests were abrasive and oxidative wear

Caracterização do óleo de carnaúba para uso como biolubrificante

Lubricant is responsible for reducing the wear on the friction protect the metal against oxidation, corrosion and dissipates excess heat, making it essential for the balance of a mechanical system, consequently prolonging the useful life of such a system. The origin of lubricating oils is usually mineral being extracted from the petroleum. But the search for a new source of production of lubricants and fuels it is necessary to meet future demands and reduce the possible environmental damage. For this reason, looking alternative means to produce certain products derived from petroleum, such as biodiesel, for example. Returning to the realm of lubricants, also one realizes this need for new raw materials for their production. Vegetable oil is a renewable resource and biodegradable, and its use entails advantages in environmental, social and economic. The development of this project aims to characterize the carnauba oil as a lubricant plant, or biolubricant. To analyze the oil carnauba tests as checking density, flash point, fire point, viscosity, viscosity, acid number, pH, copper corrosion, thermal conductivity and thermal resistivity were developed. In addition, for conducting the wear on the friction and the gradient of the system temperature, the analysis equipment is designed for wear on the friction. Based on these results, it is observed that the oil carnauba show good correlation to its application as biolubricant

Estudo da incorporação de resíduo industrial polimérico ao CAP

This work presents the incorporation of an industrial polymeric waste into a petroleum asphalt cement with penetration grade 50-60 (CAP 50-60). The main goal of this research is the development of a polymer-modified asphalt, with improvements in its physical properties, in order to obtain a more resistant material to the traffic loads. Furthermore, the use of this polymeric waste will result in economic and environmental benefits. The CAP 50-60 used in this research was kindly supplied by LUBNOR Lubrificantes e Derivados de Petróleo do Nordeste (produced in Fazenda Belém Aracati - Ceará) and the industrial polymeric waste was provided by a button manufacturer industry, located in Rio Grande do Norte state. This polymeric waste represents an environmental problem due to its difficulty in recycling and disposal, being necessary the payment by the industry to a landfill. The difficulty in its reuse is for being this material a termofixed polymer, as a result, the button chips resulting from the molding process cannot be employed for the same purpose. The first step in this research was the characterization of the polymeric waste, using Differential Scanning Calorimetry (DSC) Infrared spectroscopy (IR spectroscopy), and Thermogravimetric analysis (TGA). Based on the results, the material was classified as unsaturated polyester. After, laboratory experiments were accomplished seeking to incorporate the polymeric waste into the asphalt binder according to a 23 experimental factorial design, using as main factors: the polymer content (2%, 7% and 14%), the temperature of the mixture (140 and 180 oC) and the reaction time (20 and 60 minutes). The characterization of the polymer-modified asphalt was accomplished by traditional tests, such as: penetration, ring and ball softening point, viscosity, ductility and flash point temperature. The obtained results demonstrated that the addition of the polymeric waste into the asphalt binder modified some of its physical properties. However, this addition can be considered as a feasible alternative for the use of the polymeric waste, which is a serious environmental and technological problem.

Implementação de um modelo computacional para estudo do processo Fischer-Tropsch em reator de leito de lama

This work aims at the implementation and adaptation of a computational model for the study of the Fischer-Tropsch reaction in a slurry bed reactor from synthesis gas (CO+H2) for the selective production of hydrocarbons (CnHm), with emphasis on evaluation of the influence of operating conditions on the distribution of products formed during the reaction.The present model takes into account effects of rigorous phase equilibrium in a reactive flash drum, a detailed kinetic model able of predicting the formation of each chemical species of the reaction system, as well as control loops of the process variables for pressure and level of slurry phase. As a result, a system of Differential Algebraic Equations was solved using the computational code DASSL (Petzold, 1982). The consistent initialization for the problem was based on phase equilibrium formed by the existing components in the reactor. In addition, the index of the system was reduced to 1 by the introduction of control laws that govern the output of the reactor products. The results were compared qualitatively with experimental data collected in the Fischer-Tropsch Synthesis plant installed at Laboratório de Processamento de Gás - CTGÁS-ER-Natal/RN

Formulação de novos combustíveis base diesel: avaliação de desempenho e emissões

The industry, over the years, has been working to improve the efficiency of diesel engines. More recently, it was observed the need to reduce pollutant emissions to conform to the stringent environmental regulations. This has attached a great interest to develop researches in order to replace the petroleum-based fuels by several types of less polluting fuels, such as blends of diesel oil with vegetable oil esters and diesel fuel with vegetable oils and alcohol, emulsions, and also microemulsions. The main objective of this work was the development of microemulsion systems using nonionic surfactants that belong to the Nonylphenols ethoxylated group and Lauric ethoxylated alcohol group, ethanol/diesel blends, and diesel/biodiesel blends for use in diesel engines. First, in order to select the microemulsion systems, ternary phase diagrams of the used blends were obtained. The systems were composed by: nonionic surfactants, water as polar phase, and diesel fuel or diesel/biodiesel blends as apolar phase. The microemulsion systems and blends, which represent the studied fuels, were characterized by density, viscosity, cetane number and flash point. It was also evaluated the effect of temperature in the stability of microemulsion systems, the performance of the engine, and the emissions of carbon monoxide, nitrogen oxides, unburned hydrocarbons, and smoke for all studied blends. Tests of specific fuel consumption as a function of engine power were accomplished in a cycle diesel engine on a dynamometer bench and the emissions were evaluated using a GreenLine 8000 analyzer. The obtained results showed a slight increase in fuel consumption when microemulsion systems and diesel/biodiesel blends were burned, but it was observed a reduction in the emission of nitrogen oxides, unburned hydrocarbons, smoke index and f sulfur oxides

À luz das inquietas sombras: a criatividade da melancolia na linguagem de Dom Casmurro

Qué se piensa aquí, esencialmente, está a mapear el itinerario de la melancolía creativa en el discurso de Dom Casmurro; es decir, aquél de el cual el valle narrativo de una sensación de la angustia a alçar él él las maneras de la representación en el discurso de Dom Casmurro. El árbol básico en el cual éste estimaba incurre en se basa en el acuerdo de eso que la actual melancolía en el texto del machadiano se puede analizar por las estratagemas de la lengua creativa en la intención de demostrar en él una especie del espacio virtual - el conducir de metáforas, de ironies y del exacerbamento de imágenes - por cuál se prepone el narrador construir su salvación . El propósito es analizar el uso de el proyecto del alegórico y el irónico previstos por el autor en la intención de descubrir pues tales procedimientos contribuyen para crear un texto ese desestabiliza el carácter malsano de la melancolía. Puede propagar lengua creativa de tal manera cuánto otras maneras de la representación de eso las marcas del arte utilizan. Más allá de este traz poético, la contribución de este trabajo también constituye: para componer una escena en la cual el teatralidade de la lengua de Dom Casmurro constituye drama y no tragedia. Después de la pista de los conceptos de los benjaminianas de la melancolía, alegoria, metalenguaje la ironía, vimos que éstos disalign de la voluntad que los estatutos se estabilizaron de las figuras del retórico para consistir mientras que las estrategias de los discursivas. Subyacente a este proceso es posible percibir el flash del rescate de la escritura melancholic, visto bajo luz del saturnine de una mirada que si desea alegórico, en la misma incandescencia de la risa del fáustico
