Do dizer teórico às transposições didáticas: por um exercício da contrapalavra no ensino de língua escrita no PROJOVEM

This present work is going to show some results developed in the Master Degree research and the Post Graduation project in Language studies (PPgEL) at UFRN, under the orientation of Professor Maria da Penha Casado Alves. This research has questions showed by the Programa Nacional de Inclusão de Jovens PROJOVEM. Concerned to methodology, the research is based on Applied Linguistics and it is qualitative and documental. The corpus of the research are the Manual de Orientações Gerais and the Guias de Estudo. The documents that were used for the research were Guide for general orientation and the Study Guides.The Manual de Orientações Gerais was chosen because is focused on the teacher and the Guias de Estudo was chosen because are focused on the students. The discussions and analysis were based on Bakhtin (1997; 2003), for his studies about the language in a dialogical point of view, Faraco (2001 and 2008) and Suassuna (2006) for their discussions about the Portuguese Language and Geraldi (1997; 2005 and 2006) and Antunes (2003) for their orientation and discussions about the teaching process of the written language. The analysis made in the Reference Topics point that however the program proposes a kind of rupture with the traditional way of teaching, it could not take this change to the Study Guides (Guias de Estudo). The result is a didactic material that reproduces activities based on a conception of a descriptive and prescriptive teaching. What is concerned about the proposals for the textual production, it is shown that it is given in an artificial way, without any expression and with no link to any communicative context and sometimes, with no relation to the topic it was supposed to be related to

Afecção do tendão supra-espinal e afastamento laboral

As afecções do manguito rotador, dentre elas as relacionadas ao tendão supra-espinal, são problemas comuns na população, sobretudo devido à sobrecarga ocupacional, o que leva a altos índices de afastamento do trabalho. Buscou-se, então, comparar a necessidade de afastamento de trabalho entre os diferentes estados da afecção do tendão supra-espinal e entre cinco diferentes grupos profissionais, tendo a participação de pacientes que apresentavam diagnóstico da afecção. Os indivíduos foram agrupados quanto ao estado da doença (tendinite, ruptura parcial, ruptura total) e quanto aos aspectos biomecânicos da ocupação (ramo de serviços, construção civil, trabalhadores domésticos, lavradores e seguranças). Teste qui-quadrado de Pearson, análise de dependência e teste exato para uma proporção foram realizados. Os resultados apontaram que 62 (55%) estavam afastados da atividade laboral e que os grupos com maior número de afastados foram o do ramo de serviços (38,71%) e lavradores (22,58%), segundo Pearson. A maior freqüência de casos de afastamento foi registrada no estágio de tendinite (p<0,05) pela análise de dependência e a ocupação de lavrador parece deixar o indivíduo por mais tempo afastado (p=0,02), segundo teste de Pearson.

Pothomorphe umbellata: Antifungal activity against strains of Trichophyton rubrum

Trichophyton rubrum is a dermatophyte, which can cause infections in human skin, hair and nail. Pothomorphe umbellata (L.) Miq. (Piperaceae) is a native Brazilian plant, in which phytochemical studies have demonstrated the presence of steroids, 4-nerolidylcatechol, sesquiterpenes and essential oils. The objective of this study was to analyze the in vitro activity of extracts and fractions of P. umbellata on resistant strains of T. rubrum. The microdilution plate method was utilized to test Tr1, H6 and Delta TruMDR2 strains of T rubrum; Delta TruMDR2 strain was obtained from H6 by TruMDR2 gene rupture, which is involved in multiple drugs resistance. The highest antifungal activity to all strains was observed for dichloromethane and hexane fractions of the 70% ethanolic extract which showed minimal inhibitory concentration (MIC) and minimal fungicide concentration (MFC) of 78.13 mu g/mL. This antifungal activity was also obtained by 70% ethanolic extract, which presented MIC and MFC of 78.13 mu g/mL to Delta TruMDR2, whereas the MIC values for Tr1 and H6 were 78.13 and 156.25 mu g/mL, respectively. Our results suggest the potential for future development of new antifungal drugs from P umbellata, especially to strains presenting multiple resistance. (C) 2012 Elsevier Masson SAS.

Entre júbilo e ruína: a perspectiva trágica de Nietzsche

It is investigating why reason Nietzsche affirms, in 1888, when revises his work (Ecce Homo), that to be exactly with The Birth of Tragedy it will be necessary to forget some things , and, in spite of, insist, in the same writing, in naming himself the first tragic philosopher - that is, the opposite and antipode of a pessimistic philosopher . Nietzsche elaborates in The Birth of Tragedy a theory about tragic starting from the opposition and complementarity among Apollo and Dionysian, rationalism and instinct, and in the refusal of the pessimistic perspective. The objective of the dissertation is to discuss how the theory of tragedy modifies due to the rupture with the inspiring of the first moment of the nietzschian philosophy, Schopenhauer and Wagner - maybe the such things to be forgotten about The Birth of Tragedy - and the implications of this rupture, that transforms the philosophy of Nietzsche in dissident of the metaphysical tradition. Like this, it is noticed that there is more continuity than estrangement in what concerns to the definition of tragic, just announced in 1871. By the sentence of the eternal return to the concept of will of power Nietzsche elaborates a tragic perspective, marked by the Dionysian celebration of the life, also acted through the pessimism dionisiac , defined in Gaya Science's § 370 (1881-2), and of the sentence of the love fate, enunciated in the §276 of the same work; all those concepts, discussed in this research, concentrate, decisively, the acceptance idea and statement of life, or more precisely, the decline of the tragic hero, between joy and ruin

HIGH STRENGTH CONCRETE: THE REINFORCED CONCRETE OF THE CENTURY 21(ST)

This work is about the 21st century reinforced concrete analysis under the point of view of its constituent materials. First of all it is described the theoretical approach of the bending elements calculated based on the Norms BAEL 91 standarts. After that, numerical load-displacement are presented from reinforced concrete beams and plates validated by experimental data. The numerical modellings has been carried on in the program CASTEM 2000. In this program a elastoplastic model of Drucker-Prager defines the rupture surface of the concrete in non associative plasticity. The crack is smeared on the Gauss points of the finite elements with formation criterion starting from the definition of the rupture surface in the branch traction-traction of the Rankine model. The reinforcements were modeled in a discrete approach with perfect bond. Finally, a comparative analysis is made between the numerical results and calculated criteria showing the future of high performance reinforced concrete in this beginning of 21st century.

Tratamento do Centro de Atenção Psicossocial para usuários de álcool e outras drogas CAPSad II Leste Natal/RN : uma avaliação da efetividade

The treatment for abusive users of alcohol and other drugs suffered significant modifications until arriving to the psychosocial model that is used by Centro de Atenção Psicossocial CAPSad II Eastern Natal/RN (Psychosocial Support Center). That model appears starting from Brazilian sanitary and psychiatric reforms which are expressed in the principles and propositions of Sistema Único de Saúde SUS (Unique System of Health). The Psychiatric Reform meant a rupture with the mental hospital and hospital centered treatment pattern which was destined to the abusive users of alcohol and other drugs. The new proposal offers the universalization, democratization, regionalization and completeness of the actions in the field of mental health. It gathers a strictly interdisciplinary health staff. The purpose of this study is to evaluate the effectiveness of the treatment for abusive users of alcohol and other drugs offered by CAPSad II Eastern Natal/RN. The evaluation used, as priority, the qualitative social research through an evaluating study starting from the non-experimental model. The methodological process used different instruments of data collection: bibliographical and documental researches, systematic observations at CAPSad II Eastern Natal/RN and, mainly, the semistructured interviews (21) that were accomplished with the professionals, users and relatives of CAPSad II Eastern Natal/RN. The investigation showed the effectiveness of the service and, therefore, CAPSad II Eastern Natal/RN constitute itself as the main confronting strategy to the mental hospital and hospital centered treatment pattern of caring the abusive users of alcohol and other drugs

Esophagectomy and substitution of the thoracic esophagus in dogs

OBJETIVO: Avaliar, em cadáveres de cães, uma técnica para remoção do esôfago torácico sem toracotomia e dois métodos de substituição do esôfago torácico. MÉTODOS: Foram utilizados 27 cadáveres de cães. Estes foram aleatoriamente divididos em três grupos de nove animais, em que se estudou: G1 - esofagectomia torácica total pelo método de invaginação retrógrada; G2 - esofagectomia torácica total com substituição esofágica pelo estômago inteiro; G3 - esofagectomia torácica total com substituição esofágica por um gastrotubo confeccionado de acordo com a técnica de Büchler de gastroplastia por rotação do fundo. Após a ressecção esofágica no grupo 1, a integridade da rota intratorácica foi avaliada por endoscopia e solução de azul de metileno a 1%. RESULTADOS: A ruptura da pleura visceral ocorreu em todos os animais, especialmente no terço caudal. Entretanto, a rota transtorácica mediastinal permitiu a elevação de ambos os substitutos esofágicos (G2 e G3) para a realização da anastomose com a extremidade caudal do esôfago cervical. CONCLUSÕES: A substituição por estômago inteiro apresentou menor tensão na anastomose, maior facilidade e rapidez comparada à técnica de gastroplastia por rotação do fundo. Os resultados em cadáveres suportam a realização de estudos clínicos para validação da técnica.

Efeito do diclofenaco de sódio na cicatrização da parede abdominal de ratos. Estudo histopatológico, da força de ruptura e do colágeno tecidual

Com o objetivo de estudar os efeitos do diclofenaco sódico sobre a cicatrização da parede abdominal de ratos, foram utilizados 80 animais da linhagem Wistar divididos em dois grupos: Grupo 1: formado por 40 animais submetidos à laparotomia mediana e à injeção intramuscular de soro fisiológico durante quatro dias. Grupo 2: formado por 40 animais submetidos à laparotomia mediana e à injeção intramuscular de diclofenaco sódico durante quatro dias. Animais de ambos os grupos foram analisados no 5°, 7°, 14° e 21° dias de pós-operatório, correspondendo, respectivamente à M1, M2, M3 e M4. em cada momento foram estudados 10 animais e os parâmetros analisados foram a evolução clínica, a força de ruptura, estudo histológico e o conteúdo de colágeno tecidual da parede abdominal. Os animais do grupo tratado apresentaram como complicações, deiscência e/ou hérnia incisional, perda ponderal e taxa de mortalidade, complicações estas não evidenciadas no grupo controle. Observamos também neste grupo, diminuição da força de ruptura no 7° e 14° dia de pós-operatório e diminuição da concentração de colágeno tecidual no 5°, 7° e 14° dia de pós-operatório. Ambos os parâmetros retornaram a valores normais no 21° dia de pós-operatório. Quanto ao estudo histológico, concluímos que a cicatriz da parede abdominal dos animais tratados com D.S. apresentam retardo do processo cicatricial em relação aos seus controles, caracterizado por uma menor fibrogênese, menor densidade de fibras colágenas, além de um número maior de complicações, como microabscessos, em torno dos fios de sutura.

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

Rotura gástrica por barotrauma

Barogenic rupture of the stomach is a rare complication following cardiopulmonary resuscitation, administration of nasal oxygen by catheter and diving accidents. We report a case of gastric barotrauma following oroesophageal intubation. In most cases, the tears occur along the lesser curvature, what have been already attributed to Laplace's formula and, more recently, to morphological features of the stomach.

Parâmetros de fonte de microterremotos em Cascavel-CE

In this dissertation it was studied the rupture characteristic of earthquakes of the Town of Cascavel CE, Northeastern Brazil. Located on the border of the Potiguar Basin, the Town of Cascavel is one of the most seismically active intraplate areas in the country. In this town, on November 20th, 1980 a 5,2mb earthquake occurred. This was the largest earthquake ever reported in Northeast Brazil. Studies of this region using instruments were possible after 1989, with several campaigns being done using seismographic networks. From the beginning of the monitoring to April 2008 more than 55,000 events were recorded. With the data collected by a network with six 3-components digital seismographic stations during the campaigns done from September 29th, 1997 to March 5th, 1998, estimates of source parameters were found fitting the displacement spectra in the frequency domain for each event. From the fitting of the displacement spectra it was possible to obtain the corner frequency ( ) c f and long period amplitude ( ) W0 . Source parameters were determined following Brune (1970) and Madariaga (1976) models. Twenty-one seismic events were analyzed (0.7 £ £ 2.1) b m in order to estimate the source dimension (r ), seismic moment ( ) M0 , static stress drop (Ds ), apparent stress ( ) a s , seismic energy ( ) S E and moment magnitude ( ) W M for each of the events. It was observed that the ratio between radiated seismic energy and moment seismic (apparent stress) increases with increasing moment and hence magnitude at the observed range. As suggested by Abercrombie (1995), also in this work there is a breakdown in the scaling for earthquakes with magnitudes smaller than three ( < 3.0) W M , so that the rupture physics is different for larger events. If this assumption is valid, the earthquakes analyzed in this work are not selfsimilar. Thus, larger events tend to radiated more energy per unit area than smaller ones.

Uso de 2-octil-cianoacrilato na reconstrução da cavidade anoftálmica de coelhos

OBJETIVO: Avaliar a ligação entre músculos oculares extrínsecos e esferas de polietileno poroso usando um bioadesivo. MÉTODOS: Estudo experimental envolvendo 8 coelhos albinos submetidos a enucleação do olho direto com colocação de implante esférico de polietileno poroso de 12 mm de diâmetro unido aos músculos oculares extrínsecos por meio do bioadesivo 2-octil-cianoacrilato. Noventa dias após a cirurgia os animais foram sacrificados e o conteúdo orbitário removido. em 4 animais foi realizado estudo biomecânico, avaliando-se a força de ruptura entre a musculatura e a esfera (grupo implante) e entre a musculatura e a esclera nos olhos contralaterais (grupo controle). Nos outros 4 animais foi realizada análise histológica. RESULTADO: A avaliação biomecânica revelou que a força de ruptura entre esfera-músculo e esclera-músculo foram semelhantes quando se usa o adesivo de cianoacrilato. O exame histológico mostrou reação fibrovascular no local da adesão entre a musculatura e a esfera, sem efeitos deletérios aos tecidos. Ao redor dos implantes foi possível observar pseudocápsula e no interior, neovasos e tecido fibrovascular preenchendo os espaços entre os grânulos do polietileno. CONCLUSÃO: O adesivo 2-octil-cianoacrilato mantém boa força de adesão na união entre os músculos e as esferas de polietileno poroso, com redução do tempo cirúrgico e sem efeitos deletérios aos tecidos orbitais. Desta forma, deve-se considerar o uso do bioadesivo na reconstrução da cavidade anoftálmica.
