Adrien-Marie Legendre (1752-1833) e suas obras em Teoria dos Números

The present thesis is an analysis of Adrien-Marie Legendre s works on Number Theory, with a certain emphasis on his 1830 edition of Theory of Numbers. The role played by these works in their historical context and their influence on the development of Number Theory was investigated. A biographic study of Legendre (1752-1833) was undertaken, in which both his personal relations and his scientific productions were related to certain historical elements of the development of both his homeland, France, and the sciences in general, during the 18th and 19th centuries This study revealed notable characteristics of his personality, as well as his attitudes toward his mathematical contemporaries, especially with regard to his seemingly incessant quarrels with Gauss about the priority of various of their scientific discoveries. This is followed by a systematic study of Lagrange s work on Number Theory, including a comparative reading of certain topics, especially that of his renowned law of quadratic reciprocity, with texts of some of his contemporaries. In this way, the dynamics of the evolution of his thought in relation to his semantics, the organization of his demonstrations and his number theoretical discoveries was delimited. Finally, the impact of Legendre s work on Number Theory on the French mathematical community of the time was investigated. This investigation revealed that he not only made substantial contributions to this branch of Mathematics, but also inspired other mathematicians to advance this science even further. This indeed is a fitting legacy for his Theory of Numbers, the first modern text on Higher Arithmetic, on which he labored half his life, producing various editions. Nevertheless, Legendre also received many posthumous honors, including having his name perpetuated on the Trocadéro face of the Eiffel Tower, which contains a list of 72 eminent scientists, and having a street and an alley in Paris named after him

Os agentes funerários e a morte: o cuidado presente diante da vida ausente

The present time is marked by the art of escape from death, which has become synonymous with failure, its exposure has become intolerable and the care of the dead body were assigned to third parties who market this practice through services and products that shape the market undertaker. In this context, in which death is an object of study, has arisen funeral officers, as professionals dealing with a dead body, with the pain of relatives and their reactions, often being the first to have contact with the death scene. As professionals in the health area, the morticians also deal with death. The first attempt to prevent the arrival of death, funeral officers already has begun their work routine from there. Death and its surrounding part of their profession. What about those professionals whose work demands as a feared and denied by society? This study aims to understand the intents, meanings and implications for the mortician to deal with death in their daily work in order to focus renewed attention to the care of these professionals. To this end, it was carried out a qualitative research grounded in the theoretical framework of Gadamerian hermeneutics for production and interpretation of narratives. It was used two methodological strategies for data collection: in-depth interview with script and workshop with the use of "scenes". Research participants were nine morticians funeral of two funeral agencies of the city of Natal. It was possible to detect the presence of the social imaginary of interdiction on the theme of death from living with feelings of his presence daily, from the need of respondents to naturalize their contacts with death, a requirement of their office to deal with the difficulties of manipulating body fluids and odors, sometimes in a state of decomposition; allied to wishes to achieve the goal of delivering to family-customers a "embellished" body for the final farewell. Being a mortician, in addition to not being a professional motivation, involves facing difficulties related to heavy routine work, low salaries, unprofitable work materials and equipments, besides having to deal with the social gaze that devalues the profession. In turn, they also deal with the pain coming especially from contact with family members, either when they are targets of these feelings of anger, whether they identify with the pain of the bereaved ones. On the other hand, when the recognition and gratitude of the families occur, they find meaning and beauty in their profession of caring for the dead body. The present study by giving voice to morticians has become possible to understand better their profession, the pain that surrounds and care needs of these workers. Finally, it has argued that the mortician may be recognized as a care professional for the way exercising caution with the dead body and their families.

Imaginários da morte: poética das imagens em cemitérios brasileiros

The thesis presented is committed to a poetic reading that results in the creation of meaning and images of the death from the various cultural practices and symbolic representations exposed in urban cemeteries in some Brazilian cities, aiming to give visibility to new understandings about the imaginary of the in the contemporary scene. Death, therefore, will be seen as a imagining condition of anthroposwhen starts itself from the prerogative of the human consciousness of death (MORIN, 1970), in other words, this awareness that man has he will die and that triggers reflections about their existence allows the emergence of a number of practices such as: mourning, funeral rituals and the creation of several impregnated representations of human emotions emerged from the death facing the man and present, in a more evident form in cemeterial spaces. For this, it focuses on the conflictuous dimension that man establishes with death, because the cultural practices and symbolic representations observed in the research field are the result of this conflict and allow the expansion of the senses about this issue, to the extent that these are coated with a fantastic aura, mystical, secret, spooky, fearful, religious, building a complex imagination. The general plan of this study is to discuss and create, from a phenomenology of imagination and materials / dynamics imagination, as well as along the lines treated by Gaston Bachelard, images of death, from a field experience in cemeteries in Brazil. For this, it is assumed, to observe the cultural practices and symbolic representations in these spaces, a posture able to make the experience into the search field a moment of symbolic exchanges and creation. Thus, it was used observation, conversations with visitors and employees of the cemeteries and the capture of photographic records. The data produced as a fragment of a conversation, a tearful outburst about the loss of a relative, a melancholic epitaph, a flower on the grave or a cry captured by photography were seen as detonators of meanings and a poetic of the imagination.
