Ver, lembrar e narrar: a conformação das memórias sobre a ditadura militar na recepção assistida do audiovisual

Subjective and socially constructed instance, the memory is not a natural phenomenon, but an area of contention between various social organizations for control and legitimation of a past. With the development of writing and the advent of new technical devices, it creates new ways to store and transport information. The memory is no longer restricted to the limits of the here and now of the subject and undergoes transformations. In this scenario, the media start to play an important role in publicizing and construction of embodiments of memory. This study aims to analyze the conformation of the memory of political groups during the process of receiving audiovisual fiction. For this purpose, a corpus of four chapters of the soap opera Love and Revolution was used as a cognitive device for remembering. The television series, broadcast by SBT between April 2011 and January 2012, went back to the beginning and development of the military dictatorship in Brazil, in the cities of Rio de Janeiro and São Paulo. Three militants of various affiliations Communists who acted against the regime in Rio Grande do Norte and neighboring states, were participants in this study. Using the method of oral history, the research was divided into two stages: in-depth interviews, which dealt with the history of life of employees with the militancy in the Communist parties and other social movements, and the assistance of a drive dramatic soap opera Love and Revolution. Comparing these two phases of the study, we analyze the flow of mediations that crossed memories of militancy and media framework; shifts the narrative of remembrance during reception, and the opposition between memory and represented the experiences of the receivers

Avaliação termoanalítica da eficiência de antioxidantes na estabilidade oxidativa do biodiesel de mamona

The biodiesel is defined as the mono-alkyl ester derived from long-chain fatty acids, from renewable sources such as vegetable oils or animal fat, whose use is associated with the replacement of fossil fuels in diesel engine cycle. The biodiesel is susceptible to oxidation when exposed to air and this process of oxidation affects the quality of fuel, mainly due to long periods of storage. Because of this, the oxidation stability has been the focus of numerous researches since it directly affects the producers, distributors and users of fuel. One of the possibilities to increase the resistance of biodiesel is the autoxidation treatment with inhibitors of oxidation. The antioxidants can be used as potential inhibitors of the effects of oxidation on the kinematic viscosity and the index of acidity of biodiesel, thereby increasing oxidative stability. This work aims to examine the efficiency of antioxidants, α-tocopherol and butylated hydroxy-toluene (BHT), added the biodiesel content of remembrance through Pressurized-Differential Scanning Calorimetry (P-DSC), Thermogravimetry (TG) and Petrology. The results showed that the use of antioxidant BHT, at the concentration of 2000ppm, increased resistance to oxidation of the biodiesel and oxidative induction time (OIT), which is a better result as antioxidant than the α-tocopherol. With the thermogravimetric analysis, it was observed that the biodiesel presented an initial decomposition temperature of lower tendency than that of oil, demonstrating to be more volatile, bearing great similarity to the diesel and being characterized as an alternative fuel. The rheological analysis indicated that each sample of biodiesel behaved as a Newtonian fluid

Uma ode ao livro: a educação, o bibliotecário, a formação para a vida

This dissertation argues that the book as we know it will not cease to be. It is somehow a manifesto praising the artifact of words in the scope of literature and scientific culture. The present work chooses Umberto Eco and Jean-Claude-Càrriere‟s book Não contem com o fim do livro (2010) as cognitive operator. It presents a brief overview of the evolution of the informational supports and narrates a history of the book as constructed by complex bases; it also highlights the permanent and current state of the book having in mind the concept of contemporary as proposed by the Italian philosopher Giorgio Agamben, as opposed by the ephemeral character of the technological informational supports; moreover, it elects the book as a tool for the learning of Science and Culture, as a school for life, as put by Edgar Morin when referring to the Romance genre, in some of his works regarding Education; it presents as supporting evidence, two interviews with book-lover scholars from the Federal University of Rio Grande do Norte. Science thinkers like Edgar Morin, Maria da Conceição de Almeida, Ilya Prigogine, Giorgio Agamben, Pierre Levy, Umberto Eco, Roger Chartier, among others are used as sources of theoretical references. The dissertation places itself in the interface between Literature, Complexity and Education.
