Os anjos podem ferir: um estudo sobre a violência intrafamiliar

This work considers the comprehension of the intrafamiliar violence emphasizing violent mothers relationships with their children. The purpose is to understand the development of these relationships which turn into aggressive behavior of the mothers regarding family education. The research was carried out focusing on two aspects: analysis of the theoretical references and empirical research. The theoretical research was done through a bibliographic survey of subjects related to this study such as: the history of the family, motherhood and children, the intrafamiliar violence practiced by mothers against their children; as well as how those violent relationships emerge from family environment. We point out the Foucault s concept of discipline (FOUCAULT, 1975) and Caldeira s concept of circumscribed body (CALDEIRA, 2000). It was selected a sample of ten women to investigate the relationship between mother and son through a detailed interviews. Five mothers from this sample were denounced to the Tutelary Council and they were set in a so called Denounced Group. Similarly, the other five mothers, who live in the same social and cultural context of the selected families assisted by the Tutelary Council, were set in the Non-Denounced Group. Therefore, we work with representations of the own interviewers about the meaning of the pedagogic socializing discipline in their lives. Our priority was the study of case carried out with the denounced families for physical violence and with the other group in order to develop a comparative analysis of both groups. Such methodological choice is explained by the interest for understanding the violence between mothers and children. It is common to all mothers not to consider aggressive their behavior against their children. We observe that physical punishment is considered a way to discipline children and teenagers, hence that is perceived as necessary to repress, to control, and to adapt them. Thus, it is considered a necessary practice for education. However, the reason that made the community denounced against the mothers of the Denounced Group was due to those did not correspond to an ideal example of what was expected to be a mother (they took drugs, alcohol, and had several sexual partners), that is denounces were not for the physical violence itself. Therefore, those mothers were not denounced because they were not morally able to manage their children s education. The community tolerates the punishment against children, but not the amorality of the women, and they were denounced for disregarding their role as mothers

A previdência rural universalista e a sua relevância na economia dos municípios do Rio Grande do Norte

This study deals with the rural social security Universalist established by the Constitution of 1988 and its importance in the economy of the municipalities of Rio Grande do Norte. In this context, the study seeks to satisfy two important criteria that guide the selection of objects of social science research: a consideration of issues that have relevance to the real world and the intention to make the contribution to the scholarly literature on theoretical and empirical aspects. The research seeks to reveal what is the economic importance of the subsystem of social security for rural municipalities in RN. The hypothesis is that the transfer of income received by beneficiaries from the rural social security tax exceeds the explicit mechanisms for most municipalities in RN, in many cases significantly, proving the importance of this policy as a mechanism for combating poverty and reducing social inequality, especially before the fragility of the federal system on the national political entity hall. The study presents theoretical cores - chapters 1-3 - and empirical - Chapter 4. The first core is about the evolution of social protection as a state policy, addressing the influential theories and typologies of the State of Social Welfare and the characteristics of the Brazilian social security model, but mainly, its rural social security subsystem, its history until universalistic model inaugurated by the Federal Constitution of 1988. The second begins with an overview of studies that have emphasized the impact of Social Security on the local economy of small municipalities, then passing data and statistics in order to gauge the socioeconomic importance of pension income in the rural municipalities of Rio Grande do Norte. To this end, the final chapter provides a comparison of the monetary value transferred by the payment of social security benefits - rural and urban - to each of the 167 municipalities in RN with the equally important sources of income in the budget of municipal entities. Apart from their own tax revenues, are objects of comparison with the value of pension benefits awarded in RN, transfer quota state relating to the municipality on the federal ICMS and the transfer on the FPM

Viabilidade econômica dos sistemas manual e mecanizado de aplicação de herbicidas em ferrovias

A aplicação mecanizada de herbicidas em ferrovias tem como principal vantagem a grande capacidade operacional, cobrindo trechos extensos em curtos espaços de tempo. Entretanto em função das características dos equipamentos utilizados, quase sempre ocorre grande desperdício de herbicida. A aplicação manual, através de pulverizadores costais, tem como principal vantagem a possibilidade da pulverização dirigida às áreas infestadas, diminuindo a quantidade de herbicida aplicado. Por outro lado, sua reduzida capacidade operacional faz com que a aplicação de longos trechos seja demorada, tornando-a, assim, mais dependente dos problemas climáticos e operacionais da ferrovia. O objetivo do trabalho foi realizar uma análise comparativa das características operacionais e econômicas destes sistemas de aplicação, apontando os fatores mais importantes a serem avaliados para a sua implantação. Para tanto, foram realizadas simulações em computador, baseando-se em diversas equações matemáticas e dados levantados no campo. Os resultados mostraram que a aplicação manual apresentou-se mais econômica apenas para trechos com baixas infestações (até 10%, e média). Na composição de custos, os gastos com herbicidas corresponderam a cerca de 80% do total para a aplicação mecanizada e apenas 8% na manual. Levando-se em conta os fatores operacionais e de mão-de-obra, em apenas um dos trechos avaliados houve vantagem econômica do uso da aplicação manual.

Estudo de um isolante térmico para tubos fabricado em material compósito

It presents a new type of insulation for ductwork hot water, which can be used in solar systems for heating water, which consists of a composite of different compositions based on plaster, cement and EPS ground, palm and water. This composite has as its main features easy assembly and manufacturing processes and low cost. Comparative results will be presented on the tests of materials and thermal tubes proposed. Four formulations were used to manufacture tubes with three diameters 70, 65 and 42mm. It was also tested conventionally used for elastomeric foam insulation to 110 ° C, for a comparative analysis with the composite pipe insulator proposed. It will demonstrate that the cost of manufacturing of such tubes is competitive with alternative elastomeric foam tested, but results of the composite tube to the temperature range studied, are lower. Another drawback of the composite insulator tube is its large mass. It would be important to test such a composite for greater levels of temperature to a diagnostic technique competitive with conventionally used insulators. A positive factor of using the proposed composite-tube would be the recycling of EPS so damaging to the environment, representing an environmentally friendly application of science

Tubulações de PRFV com adição de areia quartzosa visando sua aplicação na indústria do petróleo

Fillers are often added in composites to enhance performance and/or to reduce cost. Fiberglass pipes must meet performance requirements and industrial sand is frequently added for the pipe to be cost competitive. The sand is added to increase pipe wall thickness, thus increase pipe stiffness. The main goal of the present work is to conduct an experimental investigation between pipes fabricated with and without de addition of sand, to be used in the petroleum industry. Pipes were built using E-glass fibers, polyester resin and siliceous sand. The fabrication process used hand lay up and filament winding and was divided in two different parts: the liner and the structural wall. All tested pipes had the same liner, but different structural wall composition, which is the layer where siliceous sand may be added or not. The comparative investigation was developed considering the results of longitudinal tensile tests, hoop tensile tests, hydrostatic pressure leak tests and parallel-plate loading stiffness tests. SEM was used to analyze if the sand caused any damage to the glass fibers, during the fabrication process, because of the fiber-sand contact. The procedure was also used to verify the composite conditions after the hydrostatic pressure leak test. The results proved that the addition of siliceous sand reduced the leak pressure in about 17 %. In the other hand, this loss in pressure was compensated by a stiffness increment of more than 380 %. MEV analyses show that it is possible to find damage on the fiber-sand contact, but on a very small amount. On most cases, the contact occurs without damage evidences. In summary, the addition of sand filler represented a 27.8 % of cost reduction, when compared to a pipe designed with glass fiber and resin only. This cost reduction combined to the good mechanical tests results make siliceous sand filler suitable for fiberglass pressure pipes

Molecular characterization of two Brazilian isolates of Lettuce mosaic virus with distinct biological properties

Efetuou-se a clonagem e seqüenciamento do gene que codifica a proteína capsidial de dois isolados do vírus do mosaico da alface (Lettuce mosaic virus, LMV) provenientes do estado de São Paulo, previamente caracterizados como pertencentes aos patótipos II (AF198, incapaz de infetar cultivares com os genes de resistência mo1¹ ou mo1²) e IV (AF199, capaz de quebrar a resistência propiciada pelos genes mo1¹ e mo1²), com base na virulência em cultivares diferenciadoras. Análise comparativa das seqüências de nucleotídeos de isolados provenientes da Europa, América do Norte, Oriente Médio e os dois isolados brasileiros não permitiu sua separação em estirpes, pois as porcentagens de homologia foram sempre superiores a 95%. Entretanto, análise filogenética dos isolados sugere uma origem comum entre o isolado AF-198 e os isolados LMV-R e LMV-0 (patótipo II, provenientes dos Estados Unidos e da França, respectivamente). O isolado AF199 apresentou uma alta homologia de seqüência com os isolados LMV-Aud e LMV-13, ambos provenientes da França. Esses isolados também são relacionados a isolados provenientes do Chile, embora uma origem comum não seja proposta. Eventos independentes de mutação podem estar ocorrendo em diferentes partes do mundo, propiciando o surgimento de novas estirpes de LMV capazes de quebrar a resistência conferida pelos genes mo1¹ e mo1².

O chiste em Tutaméia: riso que (des)vela

The aim of this paper is to present the study of the laughter in Tutaméia, by João Guimarães Rosa, throughtout the four forewords and ten novels selected from the author s literary work. It is based on the psychoanalytical theory of Sigmund Freud and Jacques Lacan about the laughter (and delight in the humorous nuances) and the unconscious mind. By taking the laughter as the point of exploitation and understanding, the narration can be understood from an esthetical pattern established on the variety of orallity retained by the narrator and the cordel pamphlets (known as string literature ) and its bypassing on the classical literature and the popular literature revealing its own logical linguistic and conception apart from the official one. It is taken a comparative conception of life in the François Rabelais characters and some characters from Tutaméia having Melim-Meloso as a paradigm showing how one s life can be happy in spite of all adversities by using laughter as the antidote potion against human being s misery and pain to achieve sense of freedom and pleasure

Lógica condicional

The main goal of this work is to clarify the central concepts involved in the study of formalization of conditional sentences. More specifically, it has been done a comparative analysis of the two greater and more traditional proposals of conditional formalization (Lewis 1973c e Adams 1975). These proposals were responsible for the creation of a way of analysis that still present in the current debate about this subject. This work pursues to explain the principal assumptions held within these proposals. According to certain disambiguation techniques from Bennett (2003) and Lycan (2005), this work tries to explicit how these assumptions connect to the aims sought by the initial approaches. The following results show that there is a not declared presumption, the definition of the object of study of these theories, i.e., the definition of conditional sentence. This work argues that despite of not explicitly declared the definition of the study object has a central role in the intelligibility of the debate itself
