O Tetraneto Del-Rei é uma obra que mescla linguagens, gêneros, discursos e tece, nesse emaranhado de fios, um texto original que recria parte de nosso período colonial questionando destrutivamente o discurso cristalizado pela história e mesmo por textos que compõe nosso cânone literário. Os textos utilizados na obra do paraense Haroldo Maranhão são reconstruídos num tom, sobretudo crítico, revelando uma outra visão do processo de colonização. Assim, partindo da produção literária dos países com colonização semelhante ao nosso, inicio a leitura considerando alguns trabalhos como os de Silviano Santiago, Antonio Candido e Roberto Schwarz. Além disso, há que se considerar aspectos históricos e sociais da empreitada portuguesa e dos discursos construídos acerca das terras recém descobertas e dos seus habitantes, discursos esses que serão reafirmados e reconstruídos pelo texto literário. Nesse sentido, serão utilizados alguns textos quinhentistas que auxiliarão a demonstrar os aspectos do discurso colonial e sistematizá-los com base em Eni Orlandi, Homi Bhabha e Michel de Certau. Ademais, serão observadas as estratégias textuais escolhidas por Haroldo Maranhão para recriar ficcionalmente nosso período de colonização.

Nesse trabalho, foram caracterizadas algumas argilas coletadas nos municípios de São Luís, Rosário, Pinheiro e Mirinzal. A caracterização foi realizada através dos ensaios de difração de raios X, massa específica real, capacidade de troca de cátions (CTC), área superficial, distribuição granulométrica, análise química, análise térmica (TG-DTA) e limites de Atterberg. Ensaios tecnológicos de retração linear, antes e após a queima, absorção de água e tensão de ruptura a flexão, em três pontos, foram realizados em corpos de prova prensados uniaxialmente a 20 MPa e tratados termicamente em 850, 950, 1050, 1150 e 1250ºC. Os resultados obtidos permitiram identificar duas argilas de queima branca, constituídas de quartzo, caolim, feldspato e anatásio, com excelentes propriedades para uso em cerâmica branca. As restantes são queima vermelha e possuem composição mineralógica de quartzo, caolim, feldspato, montmorilonita, hematita e goetita. Estas últimas apresentaram valores moderados de plasticidade e são adequadas para aplicações em cerâmica vermelha.

Esta pesquisa tem como propósito geral compreender as práticas sociais coletivas à saúde no "Assentamento Mártires de Abril" (AMA). É um estudo do tipo qualitativo, com a compreensão dos dados à luz da hermenêutica-dialética, que teve como cenário a ilha de Mosqueiro, área metropolitana de Belém, Pará; os sujeitos sociais foram em número de cinco, que aderiram espontaneamente à pesquisa. As práticas sociais coletivas à saúde no AMA são construídas e dependentes de aspectos históricos de vida, da luta do Movimento dos Trabalhadores Rurais Sem Terra (MST), da concepção de saúde-doença e da sua relação com a terra. Concluiu-se que suas ações expressam uma forma de cuidar essencialmente orientada pelas vias naturais, propondo à enfermagem um novo modelo de atenção à saúde. Com base nos estudos efetuados, sugere-se como prática pedagógica do Curso de Enfermagem da Universidade do Estado do Pará (UEPA) um estágio de vivência com e nos movimentos sociais.

O objetivo deste trabalho foi elaborar um produto matinal extrusado de quirera de arroz e bandinha de feijão, além de verificar a influência do processo de extrusão nas suas características físico-químicas, nutricionais, tecnológicas e sensoriais. O produto final apresentou teor considerável de proteínas (9,9 g.100 g-1), podendo ser considerado uma boa fonte desse nutriente para crianças e adolescentes. Para a fibra alimentar, observou-se teor de 3,71 g.100 g-1 do produto pronto para o consumo. Dessa forma, o floco matinal de arroz e feijão pode receber a alegação de alimento fonte de fibras, de acordo com a legislação brasileira. Com relação às propriedades tecnológicas, o extrusado estudado apresentou índice de expansão de 8,89 e densidade aparente de 0,25 g.cm-3. Quanto à análise sensorial, o floco matinal avaliado obteve notas médias de aceitação, situadas no intervalo de 6,8 a 7,7, que corresponde às categorias "gostei ligeiramente" e "gostei muito". Para a intenção de compra, 79% dos provadores opinaram que certamente ou possivelmente comprariam o produto. O emprego de quirera de arroz e bandinha de feijão é uma interessante alternativa para a elaboração de produto matinal extrusado, apresentando boas qualidades de ordem nutricional, tecnológica e sensorial.

As reflexões tecidas neste texto decorreram de inúmeros questionamentos acerca da necessidade de se considerar a importância dos contos infantis como literatura, na formação humana e na educação. Nesse sentido, aborda-se, num primeiro momento, aspectos históricos da origem e trajetória dos contos infantis. Após e ainda que brevemente, abordam-se alguns fundamentos discutidos entre Habermas e Mead sobre a construção da intersubjetividade humana que pode ser propiciada pelos contos infantis e a conquista da individuação e socialização. Por fim, são abordados aspectos a partir dos quais se espera contribuir para as reflexões sobre educação, centralmente sobre a educação de crianças em processo de escolarização.

This article discusses the relationships between the educational levels in São Paulo, focusing in some aspects such as the integration process (higher and basic education) and the access to the public higher education institutions. Starting on analyses of those relations in the context of the educational policy of the last decades, we question the eicacy of the recent proposition named Pimesp (Program of inclusion with merit in the public higher education of São Paulo) to transform the great structural lines of these access mechanisms and integration. It is supported that programs like this, in one hand, are not new and, in the other hand, they reinforce some tendencies which are already in progress in the policies to the Brazilian higher education since 1990s. Besides that, they are not able to improve the efective conditions of the secondary public education. In the inal part we state that to face these conditions of access and the possibility of a greater integration between the levels of teaching is necessary a set of systemic educational policies, with massive public investments, long term planning, among other things that are not on the horizons of Pimesp.

The civil construction sector has been stimulated to industrialize itself by the adoption of lean production practices in its constructive process. Given this fact, this research verify and identify good practices and difficulties in implementing lean production in construction companies in the State of São Paulo, in order to be able to formulate recommendations to potentiate the performance of the lean concepts applied. The research method used was a multiple case study, where the companies analyzed are constructors that have already initiated the lean application in their systems. From the results, a case analysis was conducted in order to note the constructors' situation in relation to lean construction and, base on this analysis, recommendations were proposed for the companies reflect on lean principles and apply them along to your construction management

Dissatisfaction with certain aspects of the educational processes of the traditional teaching has always existed, and new teaching methods have been routinely studied. The experimental investigative activity is one of those alternative practices. In this type of activity the experimentation is inserted with an investigative approach, in which the student must build the concept, with proposals that represent solutions to the excited problems. In the teaching of chemistry, specifically, the need and importance of experimentation is evident, beyond motivate students, aid in the understanding of chemical concepts relating them to reality. Realizing the contributions of this methodology for teaching and learning, through this research was conducted to understand the difficulties encountered by teachers for planning and implementation of these activities in the teaching of chemistry and therefore the reasons for the dominance of traditional teaching method. The subjects were undergraduate students of chemistry course that developed and implemented differentiated learning activities for teaching and teachers who accompanied the high school students who participated in the university extension project Inclusion Science and University students and teachers from public: Teaching and Learning Chemistry focuses on research and practice”. Through the data it was possible to identify some factors that affect and hinder the implementation of experimental activities in general, not only the investigative. However, despite the difficulties experienced by undergraduates, the majority considered the activity as an alternative teaching method interesting and innovative, able to produce interest, motivation and participation of students with subsequent learning. As well as the teachers, what with all the difficulties that they had declared facing when applying experimental activities, they admitted the pedagogical...

In the last years, the use of industrialized systems of lattice structures of wood as an alternative in the construction processes, is becoming more popular in Brazil, mainly for their commitment to the environment.The industrialized system of wooden lattice structures consists in a production of lattice structures, composed of pieces of wood where their mechanical connections are made with the sheet multi-toothed connectors (CDE).Among the many challenges to make this system competitive, the whole system of the connections between the pieces of wood not only must show functionality, but also speed, strength, versatility and economy. Referenced at Brazilian Standard for Wood Structures (NBR 7190/1997 - Project of timber structures) the sheet multi-toothed connectors, are analyzed using three test methods: tensile strength parallel to grain, tensile strength normal to the fibers and shear strength, all of them in two positions, αCH0=0o e αCH0=90o to four types of wood: Angelim (Vatairea heteroptera Ducke); Red-Angico (Parapiptadenia rigida (Benth) Brenae); Garapa (Apuleia leiocarpa (Vog.) Macbr) and Jatoba (Hymenaea stilbocarpa Hayne), belonging to the Leguminosae family and founded in several regions of Brazil.The purpose of this manuscript consists to analyze the mechanical connections with the sheet multi-toothed connectors through tests from NBR7190/1997

The growth of urban population associated with the shortage of supply of public infrastructure such as hospitals, kindergartens, schools, among others, has reinforced the need to develop alternative methods that simplify the construction processes and allows for a reduction in these costs works. The conventional processes have increasingly been shown ineffective to solve the problem of demand for different types of urban and rural buildings. Given this fact, industrial construction processes can gain space and have proven to be highly interesting to solve the above problems, in particular, considering the cost-effective and time. Therefore, this study aimed to determine the influence of moisture on the strength of metal plate connections connectors (printed plate with teeth). For the sizing of the links between structural lumber using metal connectors with teeth prints; controlled process variables (drying of the wood and the different moisture contents), and finally found results and compare them with different literatures order to obtain a qualitative efficiency of the process. Some specimens had very low expectations, can be explained by the presence of bone marrow, and pre-existing cracks. Thus, the results were discarded for further analysis and more accurate results

The book features profiles in which are told histories of people who, because of having leprosy, have had experienced periods of great prejudice. Even in the 80s, there were still cases of compulsory hospitalization of patients. In other words, people were forced to withdraw from society because they had Hansen's disease. The narrative of the personal histories, at the book, is broken by explanations regarding to the disease and by the development of important aspects concerning the historical theme
