Flexural Test on Recycled Polystyrene

In socio-environmental scenario increased the nature resources concern beyond products and subproducts reuse. Recycling is the approach for a material or energy reintroducing in productive system. This method allows the reduction of garbage volume dumped in environment, saving energy and decreasing the requirement of natural resources use. In general, the ending of expanded polystyrene is deposited sanitary landfills or garbage dumps without control that take large volume and spreads easily by aeolian action, with consequently environmental pollution, however, the recycling avoids their misuse and the obtainment from petroleum is reduced. This work recycled expanded polystyrene via merger and/or dissolution by solvents for the production of integrated circuits boards. The obtained material was characterized in flexural mode according to ASTM D 790 and results were compared with phenolite, traditionally used. Specimens fractures were observed by electronic microscopy scanning in order to establish patterns. Expanded Polyestirene recycled as well as phenolite were also thermo analyzed by TGA and DSC. The method using dissolution produced very brittle materials. The method using merger showed no voids formation nor increased the brittleness of the material. The recycled polystyrene presented a strength value significantly lower than that for the phenolite. (C) 2011 Published by Elsevier Ltd. Selection and peer-review under responsibility of ICM11

Aproximações do teatro do oprimido com a Psicologia e o Psicodrama

O presente artigo aborda as aproximações do teatro do oprimido na modalidade do arco-íris do desejo, método de terapia e teatro criado por Augusto Boal com a Psicologia, em especial com o psicodrama. O teatro do oprimido é frequentemente comparado e até mesmo confundido com o psicodrama, daí a necessidade de apontarmos algumas semelhanças e diferenças entre os dois métodos, as teorias que inspiraram seus criadores, bem como os objetivos que procuravam alcançar. Procuraremos problematizar o uso das técnicas do arco-íris do desejo considerando a função e a preparação do curinga para aplicá-las, seu manejo, bem como o lugar de autoridade que lhe é conferido. As técnicas boalianas devem ser utilizadas com o devido cuidado, pois é necessário não perder de vista as possíveis consequências que o seu uso indevido pode provocar nos participantes, posto que são técnicas mobilizadoras de fortes conteúdos emocionais.

Epidemiologia do transtorno obsessivo-compulsivo: uma revisão

Os inquéritos populacionais são importantes, pois amostras clínicas tendem a apresentar vieses de seleção. Aspectos sociodemográficos e relacionados à própria condição mórbida podem interferir na procura por tratamento. Pela natureza egodistônica do transtorno obsessivo-compulsivo, seus portadores tendem a ocultar o problema, podendo não procurar ou demorar a procurar tratamento. Porém, a maior parte do conhecimento atual sobre o transtorno obsessivo-compulsivo advém de amostras clínicas, que não representam a totalidade dos casos. Foi feita uma revisão convencional da literatura através do Medline, PsicoInfo e Lilacs de inquéritos populacionais sobre o transtorno obsessivo-compulsivo, cobrindo o período de 1980 a 2004, utilizando-se como palavras-chave epidemiologia, transtorno obsessivo-compulsivo, inquéritos populacionais e prevalência. Estudos realizados em diferentes países indicam para o transtorno obsessivo-compulsivo uma prevalência atual em torno de 1,0% e ao longo da vida de 2,0 a 2,5%. Diferentemente de amostras clínicas, em quase todas as amostras populacionais há predomínio de mulheres e portadores que têm apenas obsessões. A freqüente comorbidade com outros transtornos mentais, particularmente depressão e outros transtornos ansiosos, repete-se em casos da população geral, que apresentam ainda uma associação com abuso de substâncias. Muitos portadores não estão em tratamento, particularmente os casos puros. Indicadores de incapacitação funcional demonstram um considerável impacto negativo do transtorno obsessivo-compulsivo. É preciso melhorar o conhecimento da população e dos profissionais de saúde sobre os sintomas do transtorno obsessivo-compulsivo para aumentar a procura de atendimento, assim como a correta identificação e abordagem terapêutica deste grave problema de saúde.

Ocular Reconstruction After Zygomatic Complex Fracture With Retention of a Foreign Body

Facial injuries with the retention of foreign bodies inside the tissues, both in soft and hard ones, can cause major functional and aesthetic damage. Among the different etiological agents, cutting tools, fragments of a firearm, the splinter of wood, steel, or iron, launched by misuse, or even caused by defects in equipment, are the main cause of these injuries. The aim of this study was to discuss the peculiarity of the multidisciplinary approach in caring of a 33-year-old man, victim of an accident at work, by the rupture of an emery disc and consequent penetration of the fragments in violation of the tissues in the orbital and zygomatic region of the left side, with perforation of the eyeball and orbital-zygomatic fracture. Urgent treatment consisted of debridement of wounds, bleeding control, removal of foreign bodies, fracture reduction with rigid internal fixation, and suture, performed by the oral and maxillofacial surgical team. Reconstruction of orbital tissues by the ophthalmology team consisted of suture of the injuries. About 1 month after the trauma, phthisis bulbi was noted, and the patient underwent a new procedure under general anesthesia for eye evisceration and installation of an alloplastic prosthesis associated with the homogenous sclera. Facial harmony was restored, especially in aesthetics and function of the zygomatic-orbital complex.

SIG - SPRING aplicado na determinação da capacidade de uso das terras da microbacia do Ribeirão Pouso Alegre - Jaú (SP)

A população mundial vem sofrendo, cada vez mais, as conseqüências das agressões efetuadas pelo homem ao meio ambiente, principalmente quanto à ocupação e uso inadequado das terras, o que ocasiona empobrecimento e depauperamento do solo, influenciando na qualidade e disponibilidade de água, levando à destruição das reservas florestais. Assim, é necessária a implantação de políticas públicas, que contemplem o desenvolvimento econômico, urbano, rural e social de uma região, preservando os recursos naturais para futuras gerações. A bacia em estudo está localizada entre as coordenadas UTM 764942; 7546214 e 741816; 7534759, com uma área de 14699,7ha. Este trabalho visou definir as classes de capacidade de uso de terra da microbacia do Ribeirão Pouso Alegre - Jaú (SP) através do Sistema de Informações Geográficas - SPRING. A carta de capacidade de uso da terra foi elaborada a partir do cruzamento das cartas clinográfica e de solo, que foram elaboradas pelo SIG Spring, e o cruzamento de dados foi feito através do LEGAL - Linguagem Espacial para Geoprocessamento Algébrico. Os resultados mostraram que a microbacia é constituída essencialmente pelas classes II e III e o SIG-SPRING permitiu através dos seus módulos discriminarem e quantificar as áreas das classes de terras, declive e capacidade de uso da terra rapidamente.

Multimedia selection: Allowing educators to act critically and independently

In Brazil, important portals like the Portal do Professor, or Teacher's Portal, from the Ministry of Education, offer multimedia products like audios, videos, games, animations, simulations and others with an accompanying teacher's guide. These guides in general suggest ways to prepare the students to use the products while offering indications on how to practice that knowledge after using the products in the classrooom. Despite this, portals with huge repositories that receive new products every week don't present to teachers a solution for a problem: How to select the appropriate products to use in the classroom and how to assess their use after teaching in order to check if the learning was meaningful? In this way, this paper discusses multimedia selection for meaningful learning while considering concept mapping and abstraction classification. The development of multimedia repositories has created both opportunities for easy access to digital content and areas of serious concerns since the misuse of products by teachers may lead to different problems.

Mesh cancer: long-term mesh infection leading to squamous-cell carcinoma of the abdominal wall

Purpose: It is recognized that chronic inflammation can cause cancer. Even though most of the available synthetic meshes are considered non-carcinogenic, the inflammatory response to an infected mesh plays a constant aggression to the skin. Chronic mesh infection is frequently the result of misuse of mesh, and due to the challenging nature of this condition, patients usually suffer for years until the infected mesh is removed by surgical excision. Methods: We report two cases of squamous-cell carcinoma (SCC) of the abdominal wall, arising in patients with long-term mesh infection. Results: In both patients, the degeneration of mesh infection into SCC was presumably caused by the long-term inflammation secondary to infection. Patients presented with advanced SCC behaving just like the Marjolin's ulcers of burns. Radical surgical excision was the treatment of choice. The involvement of the bowel played an additional challenge in case 1, but it was possible to resect the tumor and the involved bowel and reconstruct the abdominal wall using polypropylene mesh as onlay reinforcement, in a single stage operation. He is now under adjuvant chemotherapy. The big gap in the midline after tumor resection in case 2 required mesh bridging to close the defect. The poor prognosis of case 2 who died months after the operation, and the involvement of the armpit, groin and mesenteric nodes in case 1 shows how aggressive this disease can be. Conclusion: Infected mesh must be treated early, by complete excision of the mesh. Long-standing mesh infection can degenerate into aggressive squamous-cell carcinoma of the skin. © 2013 Springer-Verlag France.

Pausas e constituintes prosódicos na interpretação de atores

Pós-graduação em Fonoaudiologia - FFC

Distribuição de pausas na interpretação de atores

Introduction: The literature about the work with the voice of actors in the theater focuses the research on organic issues involved in the vocal process as “misuse” or “vocal abuse”. To a lesser amount, there are studies that highlight issues of interpretation and expressive resources, as well as others that highlight the linguistic resources of interpretation. This work shows a linguistic feature – the pause – and its collaboration for the theatrical interpretation. Objective: to verify the extent to which similarities and differences occur between the points judged as occurrence of pauses in interpretations of a theatrical text. Method: Subjects of this study were four theater actors, who played individually a same theatrical text. Later, a group of ten judges judged the points where pauses occurred. Based on a criterion of 70% agreement between judges, were searched similarities and differences between the points judged as pause of each recording. Results: the four subjects showed different amounts of pause in the stretch in common that they interpreted: S1= ten occurrences; S2= 14 occurrences; S3= 6 occurrences; and S4= 9 occurrences. In this inter-subject variation, five points of pause in common were detected. Conclusion: we have seen, then, that this variability (featuring subjectivity in interpretation) is built inside given possibilities, with lesser or greater flexibility, by the structure of the theatrical text.
