O som do silêncio :a angústia social que encobre o luto : um estudo sobre isolamento e sociabilidade entre enlutados do cemitério Morada da Paz (Natal/RN)

Nowadays, the act of mourning configures as a circumstance of isolation and social anguish due to the impossibility to express the pain by those who suffer the loss of a dear one. At the same time, the symbolic relations established between society and the cemetery contains interpretations about death, pain and fear which confer to the visits a special and individual feature. In this context, this dissertation tries to analyse the formation of a sociability observed among visitors of the Morada da Paz a private cemetery located in Natal/RN as well as the frequency of the visitors to the necropolis. Therefore, the research was accomplished from the observation of the existent relations among these actors whose meetings have procured links based on the experiences´ exchange about pain and bereavement. In this sense, this study tries to analyse, as its principal point, in which way the Morada da Paz space and the relations established there are being appropriate by the visitors in their mourning process, trying to understand what are the role of these bond in the elaboration of the loss for these people

Efeito do isolamento térmico de telhado sobre o desempenho de frangos de corte alojados em diferentes densidades

O objetivo deste trabalho foi avaliar o efeito do uso de isolante térmico de telhado instalado como forro sob a cobertura no desempenho de frangos alojados em diferentes densidades (10, 16 e 22 aves/m²) e nas características da cama de aviário em galpão convencional. O experimento foi realizado durante o verão, utilizando 3328 aves da linhagem Hubbard, distribuídas em um delineamento inteiramente casualizado, em um esquema fatorial 3x2 (densidade e sexo), com quatro repetições dentro de cada ambiente. Para a comparação dos ambientes, utilizou-se a análise conjunta. Durante o período experimental, registraram-se dados de temperatura ambiente em vários pontos do galpão e em diversos horários, umidade relativa e carga térmica radiante. O teor de nitrogênio e matéria seca e a temperatura da cama foram determinados. No ambiente com isolante térmico, as temperaturas ambientais médias e a amplitude térmica diária foram menores e a umidade relativa do ar, maior. O desempenho das aves foi melhor no ambiente com isolante térmico, no qual as aves tiveram maior consumo de ração, maior ganho de peso, melhor conversão alimentar, menor mortalidade e maior produção por área. A temperatura retal das aves do ambiente sem isolante térmico foi mais elevada. À medida que se elevou a densidade, a mortalidade aumentou, porém a produção por área foi maior. O uso do isolante não influenciou a produção de cama, mas diminuiu a porcentagem de nitrogênio na cama. Com o aumento da densidade, a produção de cama elevou-se, pelo maior volume de excretas, mas não influenciou sua porcentagem de nitrogênio. O uso do isolante térmico permitiu aumento da densidade de criação dos frangos.

Fazer a ponte para a escola de todos(as)

The purpose of this study is to understand what are the matrix elements in which everyday activities of social author/authors, actor/actors and actress/actresses are embedded, in order to carry out the Escola da Ponte s political and pedagogic process (PPP). Thus, the object of this study is to reflect on an experience developed in a public school supported by the Portuguese State within the scenario of institutions that are committed to building up a school of the people by investing in democratization and community participation in their management process. The methodological course of action was targeted at the presuppositions of qualitative research (WOODS, 1999; BURGESS, 1997; MILLS, 1982; OLIVEIRA, 1998; BOGDAN and BIKLEN, 1994; MACEDO, 2000; CASAL, 1996; GEERTZ, 2000), with data collected from random word association (MACHADO and CARVALHO, 2003), the discourse of the interviewed (KAUFMANN, 1996; SILVA, 2006; 2002), observation notes and documents (ELIAS, 1997). Based on a multiple reference and theoretical framework, the investigation revealed elements that are construed as the raw material and pillars supporting the bridge of a school of the people, as well as the self-organization of the school community which emerges as a dimension that binds together all the elements and brings new arrangements into the school dynamics by moving from the individual to the society (DUPUY, 1990). Along this line, the central argument is that in the short and long run the public school quality does not spring from macro educational policies, nor from ephemeral mass-production programs, projects or governmental policies, but from the intent of the professionals working there in becoming authors and characters in the process of building up and carrying out the PPP. The Project has been conceived in the light of the needs and intentionality of the community whose support comes from the participation and social control held by the students families and the community s power to force to action public administration central agencies aiming at having the State fulfill its responsibilities

Sistema de detecção e isolamento de falhas em sistemas dinâmicos baseado em identificação paramétrica

The present research aims at contributing to the area of detection and diagnosis of failure through the proposal of a new system architecture of detection and isolation of failures (FDI, Fault Detection and Isolation). The proposed architecture presents innovations related to the way the physical values monitored are linked to the FDI system and, as a consequence, the way the failures are detected, isolated and classified. A search for mathematical tools able to satisfy the objectives of the proposed architecture has pointed at the use of the Kalman Filter and its derivatives EKF (Extended Kalman Filter) and UKF (Unscented Kalman Filter). The use of the first one is efficient when the monitored process presents a linear relation among its physical values to be monitored and its out-put. The other two are proficient in case this dynamics is no-linear. After that, a short comparative of features and abilities in the context of failure detection concludes that the UFK system is a better alternative than the EKF one to compose the architecture of the FDI system proposed in case of processes of no-linear dynamics. The results shown in the end of the research refer to the linear and no-linear industrial processes. The efficiency of the proposed architecture may be observed since it has been applied to simulated and real processes. To conclude, the contributions of this thesis are found in the end of the text

Detecção e isolamento de falhas em sistemas dinâmicos baseados em redes neurais

This master dissertation presents the development of a fault detection and isolation system based in neural network. The system is composed of two parts: an identification subsystem and a classification subsystem. Both of the subsystems use neural network techniques with multilayer perceptron training algorithm. Two approaches for identifica-tion stage were analyzed. The fault classifier uses only residue signals from the identification subsystem. To validate the proposal we have done simulation and real experiments in a level system with two water reservoirs. Several faults were generated above this plant and the proposed fault detection system presented very acceptable behavior. In the end of this work we highlight the main difficulties found in real tests that do not exist when it works only with simulation environments

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

As Filhas do Arco-Íris, de Eulício Farias de Lacerda : mitos, lendas e contos populares como elementos estruturantes do romance

The corpus of this work constitutes an analysis the literary work As Filhas do Arco-Íris, by Eulício Farias de Lacerda, considering object of study myths, legends and popular stories as estruturant elements of the romance. The unchainment of this reading considers aspects of the oral tradition as starting point for the rupture tradition. In that perspective, it became fundamental to describe aspects of the popular culture that consolidated the Brazilian Literature during the 20th century. Like this, it was necessary to understand the development of oral elements and the structuring of the folk-tales, pointing out that As Filhas do Arco-Íris was built in a especial way with regionalist characteristics, following the parameters of the romances published among the years 1930 and 1950. In the researched work, it was noticed a narrative that gathers stories, legends, myths, proverbs and oral locutions. In this, it reveals that the Brazilian literary production grew in aesthetics and thematic. Like this, As Filhas do Arco-Íris is an exercise of the experience regionalist inserted in the contemporary novel, because even with your first publication in 1980, the narrative is configured to the molds of a Romance de 30
