Caracterização mecânica e microestrutural de um aço baixo carbono microligado com estrutura multifásica

Neste trabalho foi realizada a caracterização mecânica e microestrutural de um aço microligado com estrutura multifásica. Foi aplicado tratamento térmico pré-determinado, objetivando a formação de uma microestrutura multifásica no material. Na caracterização microestrutural foram utilizados ataques químicos à base de metabissulfito de sódio e ácido pícrico, enquanto a caracterização mecânica foi realizada através de ensaios de tração. Os resultados demonstram o elevado potencial dos aços multifásicos em aplicações que necessitem de valores superiores de resistência e ductilidade, pois tanto para temperatura isotérmica de 400ºC quanto para 350ºC houve um ganho no limite de resistência à tração ficando em torno de 786MPa e 773MPa respectivamente, representando um aumento de 15,5% e 13,6% com relação ao material fornecido.

Efect of an educative action on relatives' knowledge about childhood burns at home

Periódicos de bioética. ¿Hay muchos? ¿Hay pocos? ¿Cuál es la situación?

This work presents a bibliometric profile of Bioethics Journal according to the following journal databases: MEDLINE, LILACS, The Philosopher' s Index, Ulrich's, SciELO and Qualis classification system (Brazil). We found that: from 38 titles indexed in MEDLINE, 25 (66%) still exist; the country with the highest number is the U. S. A (36%); most Bioethics journals appeared in the 1990's (47%), and 36% have less than 10 years of existence. From those that disappeared (34%), the average survival time was about 4 years. There are only 12 countries with indexed journals. In Brazil, from 3 Bioethics journals, only one is (partially) indexed. English is the preponderant language (45%). Only 3% of journals are monthly. LILACS has two additional publications (Acta Bioethica, Chile, and Revista Latino Americana, Colombia). SciELO has only Acta Bioethica. In Ulrich's database, there are eight additional publications. In "Qualis" classification system there are four journals.

Patients' experiences of peritoneal dialysis at home: a phenomenological approach

O objetivo deste estudo foi compreender a experiência da diálise peritoneal domiciliar, a partir da narrativa dos pacientes. A abordagem do estudo inspirou-se na fenomenologia hermenêutica de Paul Ricoeur. Foram entrevistados 19 pacientes na unidade de hemodiálise de um hospital público brasileiro, de março a setembro de 2009. As entrevistas foram orientadas pela questão: descreva sua experiência na diálise peritoneal. Os resultados desvelaram a percepção dos participantes sobre o significado da doença em suas vidas e as drásticas transformações pessoais sofridas nesse processo. Sentimentos de angústia e dor física foram acompanhados por importantes limitações pessoais e sociais, impostas pelo tratamento. Eles esperam por um futuro incerto, reconhecendo sua dependência da ajuda dos familiares e dos profissionais da saúde. Os resultados desvelam as dificuldades e a falta de perspectivas vividas pelos pacientes em diálise, demonstrando o papel crucial que cabe aos profissionais que os acompanham. Ajudá-los a desenvolver o autocuidado e maximizar sua qualidade de vida é prioridade na assistência a esses pacientes.

Autogerindo o tratamento da osteoporose no regaste do bem-estar, mediado pela (in)visibilidade de indicadores da doença

The present study aimed to understand patients' experience with osteoporosis treatment. The methodological and theoretical frameworks were, respectively, the Grounded Theory and Symbolic Interactionism. The research subjects were 12 patients monitored in a specialized outpatient unit. The obtained statements were transcribed and analyzed, leading to a synthesis of the described themes. From the analysis process, two phenomena emerged: "self-evaluating health conditions according to the disease signs" and "making a decision about the treatment targeting at well-being". The realignment and the inter-relationship of the components belonging to these phenomena (themes, categories, and subcategories) allowed to identify the core category: "self-managing osteoporosis treatment for well-being recovery mediated by the (in)visibility of the disease signs". Furthermore, it allowed for the design of a theoretical model concerning the process used by the player in his cyclic movement of the experience, between adherence to and relaxation from the osteoporosis treatment.

Com quantas ave-marias se faz uma santa? relicário de vozes sobre a santa menina

Ce travail a comme objectif analyser la structure et l'efficacité d'un système symbolique, qui est configuré à travers qui le philosophe Dufour (2000), à partir du linguiste Benveniste (1995) et du philosophe Lyotard (1998), dans la manutention et la sustentation des récits et d'histoires, appelle de trinité naturel des la langue. C'est sous cet appareil, inscrit à travers des pronomes « moi », « toi » et « lui » qui nous étudierons les suivantes questions: 1. comme s'il établit, synchronement, la mise à jour du mythe religieux Santa Menina présente dans la ville de Florânia, gêné dans le coeur broussard du Rio Grande do Norte? 2. qui manière, diachronement, les récits sur mentionné mythe s´il récupère? Le culte religieux à la Santa Menina est marqué discoursivement à travers d´un univers à facettes multiples qui se soutient à travers les voix de floranienses sur l'histoire d'une fille, dont le corps est trouvé intact et qui, sacralitée par la population, est connu comme la Santa Menina. Une histoire qui, notamment, avait/a répercussion et résonance, en participant, efficacement, des la réalité culturelle des la population. Théoriquement, notre travail est nourri par des savoirs arrivés, des la Linguistique, et des études sur la Mémoire et l'Histoire Verbale

O poema e a canção em as coisas, de Arnaldo Antunes: imagens da primeiridade

Ce travail a pour but d analyser un corpus de six textes hybrides, que nous classons comme des poèmes-chansons/ poèmes-chantés à cause de leur double présence dans deux systèmes sémiotiques différents. Le premier, la littérature, ou plus spécifiquement la poésie, a comme support le livre As Coisas [Les Choses], d Arnaldo Antunes et l autre, la chanson, est enregistré dans les disques du même auteur. Notre travail lance un regard sur ce corpus, en essayant de vérifier un aspect recourrent dans l oeuvre d Arnaldo Antunes qui est la présence da priméité, catégorie theórique développée par Charles Sanders Peirce. Au-delà de l observation de cet aspect sémiothique, nous ferons une discussion sur la chanson populaire, et ses rapports avec la poésie et par conséquent avec la Litterature. La théorie sémiothique s appuyera sur deux piliers : En ce qui concerne l étude de la priméité, nous travaillerons avec les théories de Peirce, mais en nous servant aussi des ouvrages de Lúcia Santaella, Winfried Nöth, Júlio Plaza et Décio Pignatari ; Dans l autre voie, pour ce qui concerne l analyse des chansons, nous utiliserons la théorie de Luiz Tatit, fondée sur la sémiothique de Algirdas Julien Greimas. Tatit trace une méthode d analyse, où il est possible d analyser une chanson en exploitant et le texte et la mélodie, ce qui permet une meilleure compréhension de l étude des poèmes-chansons et ses variations. Comme support pour la discussion sur la musique, nous nous servirons des théories de José Miguel Wisnik, Claude Lévi-Strauss, Roland Barthes et Jean Fisette

O eterno espanto: uma leitura estética em Mario Quintana

This work aims to read the phenomenon of the Sublime as the main aesthetical concern in the work of the Brazilian poet Mario Quintana. The research was based on the dialogical approach used by Mario Quintana to see life & poetry. This search noticed that such aesthetical concern is an answer to the modern age that surrounds the post-war man. Immerse in his aesthetical concerns, Mario Quintana designs, through his poetry, a way to give humanity back to men. In this attempt of rupture, Mario Quintana returns to tradition through astonishment besides laughter

Atividades de construção de sentido: a cosmovisão no discurso poético de a poesia em pânico

This study try to integrate concepts from referenciation theory to highlight processes of meaning construction of the book A Poesia em Pânico, written by the Brasilian poet Murilo Mendes. The concepts of referenciation, discourse objects and cognitive-experiential schemes were employed to evidence the meanings of the poems in the book, specifing its methods of elaboration and the effects of expression. Parallels beetwen the conception of language proposed by the theories used and that deduced from the poems and poetic pratice of the author studied was traced, making evident its similarities. Equaly, textuals analises are used to demonstrate various aspects of the theories. At the same time, a reading of the main elements of discourse was constructed throughout the study, trying an aproximation beetween the fields of linguistic and literary theory

Outras verdades, muito extraordinárias, do grande sertão

This study explores the symbolism of evil way in the novel Grande sertão: veredas, by Guimarães Rosa, regarding faustian pact by Goethe, and so tries to understand how the rosiana language are present to the strategies which put in suspense the effectiveness of the demonic agreement and enable, with poetic intensity, different interpretations, especially as regards the anguish of the human condition. This research thus has drawn upon the Mythical Symbolism, in Literary Criticism and aspects of Metaphysics, in addition to analyzing classic literary essays in approaching of Rosa s masterpiece structure. It has also demonstrated that the incorporation of the Faust legend in Grande sertão reflects the same desire for happiness that is not done completely, and in this manner, instigates a discussion about the limits to the satisfaction of being human. Therefore, it has observed that epic narrative of ex-gangster Riobaldo to the doctor of city speculates on human man, in the continuous learning of his passing

Oralidade e escrita: a presença do discurso reportado em entrevistas jornalísticas

In this work, we intend to discuss results from a research about retextualization in gender journalistic interview, considering speech dialogical approach. Retextualization activity, which implies the production of a new text through one or more basic texts, shows the presence of reported speech as an integral unit of discursive construction. Our corpus had been extracted from a section called Nossos Valores [Our Values], present at the syndical newspaper Adurn Notícias [Adurn News], from Federal University of Rio Grande do Norte (Brazil), which weekly publishes journalistic interviews with active professors from this institution. We describe retextualised text structure by correlating it to the one from the oral text, in order to identify and describe quoted speech, as well as features of the gender in which it is inserted. It was verified that, when it comes to reported speech present in the published interviews, which are representative of the research corpus, diverse incorporation procedures of alien property‟s speech take place, especially those regarding about reported speech use. The waterish presence of the other present in dialoged texts speech transformed in monologue texts demonstrates that there is not a clear demarcation among voices in certain parts of the written text. This is confirmed during analyses of the two interview versions, in which it is not always possible to distinguish the authorship of certain propositions, which in some way can point to Bakhtin‟s concept of intentional hybridity. Beyond Bakhtin‟s contributions (1990; 2000), the theoretical principles of this work are based upon Marcuschi (1986; 1999; 2001), Matencio (2003), Authier-Revuz (1982), and Favero et al. (1997; 1998; 1999; 2000)

Comunicação da equipe multiprofissional e indivíduos portadores de hipertensão arterial

O presente estudo tem como objetivos levantar dados sobre o que os indivíduos portadores de hipertensão arterial pensam sobre a sua doença e verificar a ocorrência do processo de comunicação entre estes e os profissionais que atuam junto aos mesmos. Foram entrevistados 66 clientes, obtendo-se 73 narrativas, constatando-se que a maioria (69 narrativas) dos participantes da pesquisa faz correlação com o conceito de hipertensão arterial, ainda que de maneira pouco elaborada. Apesar de 95% dos clientes fazerem alguma referência à doença, não significa que as orientações recebidas anteriormente foram aprendidas. Espera-se que o enfermeiro por desempenhar um importante papel dentro da equipe multiprofissional, identifique as possíveis barreiras relativas ao processo de comunicação, havendo daí a intervenção junto aos elementos que podem estar dificultando ou impedindo a compreensão necessária para que o cliente assuma seu autocuidado.

Traduzindo o economês: metáforas da inflação em textos de jornalismo econômico

The research aimed two objectives: 1st) identifying and describing the metaphors of the inflation, in a corpus of 18 texts of economic journalism, from Joelmir Beting, written in the last trimester of 2002, at the moment of the government s transition of president Fernando Henrique Cardoso to Luiz Inácio Lula Da Silva. 2nd) verifying the recognition of the metaphors by the students of the basic education of a private school from Natal. 91 metaphors had been identified, analyzed in the perspective of the conceptual metaphor s theory, by Lakoff and Johnson (2002), on the basis of the distinction between conceptual metaphor and metaphoric expressions, and between domain-source/domain-target. 10 underlying conceptual metaphors had been inferred, being that the domains-source used more frequently to characterize the inflation had been those ones according to the human being and the animals and, of a less imaginable form, to the ways of transport (car, aircraft). These general conceptual metaphors had been unfolded in other s more specific ones ( animal specifying itself in lion , dragon , dog , etc.). Another result was the identification of metaphoric expressions with two or more meanings , with relation to more than one conceptual metaphor or explicit, in the same expression, two domains-source (for example: armored dragon ) and contributes, of a relevant form, for the semantic struturation of the text. The understanding of the metaphors was verified through an activity of domains-source s identification (10 metaphoric statements and fulfilling of the gap in the phrase the inflation is a/an ) applied in a group of 8th year of the basic education (12-13 years old, with 14 girls and 17 boys) from a school of good social and economic positions from Natal-RN. There weren t great difficulties on the part of the students in recognizing the domains-source involved: about 80% to the great majority of the statements
