Os forrós da Serra da Gameleira (São Tomé/RN) : etnicidade, festa e sociabilidade

This work intends to describe and analyze the parties of forró that happen in Serra da Gameleira, in São Tomé/RN. Serra is a divided social space: groups of different ethnic origins live together in Gameleira de Baixo, Salgadinho (or Gameleira de Cima) and Chaves Belas. They are approximately two hundred families that live exclusively from agriculture. We try to understand how the parties inform about the social organization, the ethnic composition of the families that live there and the past of Serra, through the genealogy offorró players. In the discussion, we identify the festive places: in the total, we have Five houses of forró that function regularly one of them has been described. The private and public spaces inside them are intimate related, with no clear limits between the house of forró and the residence. Each house of forró has an owner, that regularly makes the parties, mobilizing a big part of the inhabitants, and provoking the straitening of the social relations. Observing the festive sociability between different social segments, the forró appears like na element that minimizes social conflicts, providing news ways of association and cooperation in the space of Serra da Gameleira. For the collection of facts, we used the ethnographic method, through the direct observation, interviewing and documentary research. The local history is recounted following the routes of oral memory and historical documents analysis. In the end of the analysis, we concluded that music and party are elements that aggregate the different groups that live in the location and determine forms of expression of what is seen as a traditional culture

Entre parentes :cotidiano, religiosidade e identidade na Serra de Portalegre/RN

Si les études sur les groupes noirs ruraux connaissent un essor dans l´Antropologie brésilienne contemporaine, au Nordeste, et spécialement au Rio Grande do Norte, ce genre de recherches restent rares. Ce travail a comme principal objectif de faire une description ethnographique des communautés du Pêga, do Arrojado e do Engenho Novo, dans la commune de Portalegre/RN, désignées comme des descendants africains et dont les membres se reconnaissent comme appartenant a une "grande famille". Ainsi, nous voulons analyser les processus d´élaboration d´une identité collective et comprendre le rôle des relations de parenté dans la vie cotidienne, festive et religieuse de Portalegre. En effet, nous pouvons observer que les "parents" développent des stratégies économiques et affirment leur alterité, reprennant des traits culturels et religieux qui leur sont propres pour se présenter comme un groupe doté d´une grande cohésion face a la société environnante. Nous utilisons la méthode ethnographique et la technique de l´observation participante, alliée à l´analyse des sources historiques primaires dans le but de décrire ces pratiques et stratégies. Nous pensons que la participation des membres du groupe à la production agricole, spécialement dans la confection de la farine de manioc, la construction des relations sociales au quotidien et l´organisation de la danse de São Gonçalo représentent autant d´occasions où la mémoire du groupe se fortifie, l´identité collective se cristallise et où la sociabilité se trouve consolidée. Nous analysons ces pratiques collectives et ces moments festifs comme des moyens de réaffirmation d´une identité locale centrée sur les relations de parenté

O corpo como matriz pedagógica

The contemporary conjuncture based on the capitalistic knowledge converges to the corporal consciousness that makes us see, feel, taste and hear, be in/to pieces. Disembodied reason legitimate and legislate ways of being and living socially and its development is the dehumanization of human relations causing pain and suffering. The objective of this work is to discuss the body as pedagogical matrix through imagistic/artistic elements: music, painting and literature. Metaphors lead to self knowledge of human subjectivity and approach us to the kaleidoscope of sensitive knowledge and enables learning to learn with the infinite combinations of images, knowledge, feelings and worldviews. The song Memória da Pele comes in the voice of Maria Betânia speak of the memories that are not mine, but are tattooed in me in the memory of skin, singing the memories of a love lived by who tries to forget rationally, but the body insists on remembering. It is password to think about what we are. The short story by Clarice Lispector, entitled Miss Algarve, narrates the life story of an unmarried and virgin woman, and her encounter with an alien called Ixtlan. Until then, she who lived as if every day were a Monday, found herself seduced by the pleasure of having a body in contact with another body, which also allowed her to give visibility to the bodies of others. She had repudiation by the immorality that her body and the other s perspired. The discovery of the body brings important lessons for nursing, involving our body and the others'. The painting the flying bed or Henry Ford Hospital, by Frida Kahlo, is our final metaphor. The traumatic experience of abortion is shown in this painting trough the picture of the artist naked in a hospital bed. This painting invites us to reflect on our work process. We need to think in multiple dimensions of the being and accept the invitation of art, so that the lightness confronts us with the weight imposed by the hegemonic ideology. I believe it is not a single view, but the many views that should justify the knowledge and practices of nursing; what matters is that they are woven into the dialogue, democracy, provided that protagonism of those individuals involved in this process, in the wandering and uncertainty, in the rewiring, solidarity, plurality. To this end, the body must be the great pedagogue that is able to be viewed not as a tapestry seen by the right view, as the logical knowledge sees, but seen by the opposite side in its singular, irregular, discontinuous weavings

Análise quali-quantitativa do deslocamento da camada-limite em carrocerias veiculares

Dois dos principais objetivos no estudo da aerodinâmica de veículos é a segurança e o desempenho. Esses objetivos podem ser alcançados através do desenvolvimento de dispositivos que modifiquem o escoamento de ar ao redor do veículo e também através de alterações da forma das superfícies externas. O perfil mais baixo da frente do veículo, por exemplo, tem grande influência sobre o coeficiente de penetração aerodinâmica (Cx) e posteriormente sobre grande parte da distribuição de pressão ao longo da superfície do veículo. O objetivo deste trabalho foi de analisar o comportamento aerodinâmico que incide sobre 2 (dois) tipos de carrocerias de veículos, baseado em experimentação em túnel aerodinâmico, visando determinar a eficiência aerodinâmica de cada uma delas. Foram comparados dois modelos de veículos, sendo um deles com configuração familiar, muito comum nas grandes cidades e outro modelo com configuração esportiva mais voltado para o desempenho, ambos com escala 1:18. Para a realização do experimento foi construído um túnel aerodinâmico do tipo soprador com circuito aberto, onde foram analisadas as distribuições de pressão nas superfícies inferiores e superiores da carroceria dos modelos e o deslocamento da camada-limite. Tomando-se por base toda a teórica deste trabalho, com relação à aerodinâmica de carroceria, considerou-se nesta dissertação que essa filosofia de pesquisa é capaz de gerar reflexos positivos, que podem tornar os veículos cada vez mais eficientes e influenciar positivamente nos níveis de segurança e desempenho

Desenvolvimento de material compósito a base de raspa de pneu e látex para isolamento térmico

The process of recycling has been stimulated by the markets for several reasons, mainly on economical and environmental. Several products have been developed from recycled materials that already exist as well as several residues have been studied in different forms of applications. The greater majority of the applications for thermal insulation in the domestic, commercial and industrial systems have been elaborated in the temperature ranges between low to medium reaching up to 180oC. Many materials such as glass wool, rock wool, polystyrene are being used which are aggressive to the environment. Such materials in spite of the effectiveness in the retention of heat flow, they cost more and when discarded take several years to be absorbed by the nature. This way, in order to adapt to a world politics concerning the preservation of the environment, the present study was intended to develop a material composed of natural/biodegradable materials and industrial residues. The development of such a product in the form of a composite material based on tyre scrapes and latex for thermal insulation is presented in this research work. Thermal and physical properties of the tire scrapes as well as latex were studied in order to use them as raw materials for the manufacture of the intended composite to be applied as a thermal insulator in hot and cold systems varying between 0ºC and 200oC, respectively. Composite blankets were manufactured manually, in weight proportions of 1:1 (50:50%); 1:2 (33:67%) and 2:1 (67:33%) (tire scrapes: latex) respectively. Physical, mechanical and thermal properties of the composites were analyzed to obtain data about the viability of using the composite as a thermal insulator. The analyses carried out were based on standards ABNT, ASTM and UL. The maximum temperature obtained for the composite as a thermal insulator was 200ºC, which meets the range of applications that could be used as a thermal insulator in domestic as well as industrial purposes. The experimental results prove that the composite can be used as a thermal insulator on heated or cooled surface
