The objective of this research is to understand whether the mathematics lessons teachers use ICT and how they see their use. For this, we prepared a questionnaire with four questions for the subjects of our research, which are ex - students of Bachelor in Mathematics FEG / UNESP, in exercise of the profession. The questionnaire data were analyzed following the procedures of phenomenological research. This approach enabled us to draw up three open categories. The first Recourse to boost student learning and school, leads us to interpret that for the interviewees, ICT resources are leading students to do research making them responsible for their learning and providing them with conditions respond the issues raised by the teacher, which generates greater interactivity. The second, Possibility to use software related to mathematical content shows that the subject sees ICT as resources that allow the study of mathematical content, especially geometry and functions, so that student learning is leverage. The third, Obstacles to the use of technology in the classroom shows that even if the subjects recognize the importance of ICT use, they do not use it as often as they would like because of the difficulties that are related to infrastructure and didactic and pedagogical conditions

A demência de Alzheimer (DA) constitui o tipo mais comum de demência. Déficits de memória caracterizam a doença e causam comprometimento de sua qualidade de vida. Sintomas depressivos são comuns na DA e associam-se a um contexto de perda da qualidade de vida. Atualmente a literatura apresenta poucos estudos envolvendo a temática atividade física na DA. O presente estudo poderá orientar novas investigações acerca da DA e auxiliar profissionais da área da saúde na orientação de cuidados para o paciente que visam reduzir sintomas depressivos e aumentar a qualidade de vida de pacientes e cuidadores. O objetivo do estudo foi analisar os efeitos da atividade física sistematizada sobre os sintomas depressivos e a qualidade de vida de idosos com demência de Alzheimer e de seus cuidadores. Dezesseis sujeitos com diagnóstico de DA foram avaliados no início e após seis meses pelos testes: Mini-Exame do Estado Mental (MEEM), escala de qualidade de vida (EQV) e Escala de Depressão em Geriatria (EDG). Seis participantes foram submetidos à sessões de um programa sistematizado de atividade física a ser realizado 3 vezes por semana, com duração de 60 minutos, por um período de 6 meses. Os demais formaram o grupo controle, que não realizou a intervenção motora. A análise dos dados consistiu da estatística descritiva, verificação da distribuição dos dados por meio do teste de Shapiro Wilk. Foi utilizada a Análise de Variância para medidas repetidas (ANOVA two-way) e o teste de correlação de Pearson. Admitiu-se nível de significância de 5% (p<0,05) para todas as análises. A ANOVA mostrou uma interação significativa entre grupos e momentos. O coeficiente de correlação de Pearson apontou que há relação entre as visões de qualidade de vida, e entre as mesmas e os sintomas...(Resumo completo, clicar acesso eletrônico abaixo)

Dans ce texte on a étudié, afin de comprendre et d'analyser les contes réalistes de Guy de Maupassant, comment Erich Auerbach, dans Mimesis (2009), parcourt les sentiers de la littérature occidentale pour dresser un tableau des traits communs qui existent entre les grandes oeuvres réalistes de l'Occident. L'auteur a réalisé des recherches et des commentaires sur les caractéristiques les plus récurrentes du réalisme littéraire dans les oeuvres d'écrivains tels que Homero, Shakespeare, Voltaire, Flaubert, parmi d'autres. Notre recherche vise, dans sa première étape, à présenter, à expliquer ou à identifier dans les contes de Guy de Maupassant, écrivain de la fin du XIXe siècle, les tendances réalistes discutées par ce théoricien et par d'autres au fil du temps, comme, par exemple, Roland Barthes, dans Crítica e verdade (2007), Bersani, dans Le réalisme et la peur du désir (1975) et Philippe Hamon, dans Un discours contraint (1973, p. 411-445). À partir de ces chercheurs, on essaie d'expliciter et d'affirmer le caractère réaliste d'un des maîtres du récit court - sûrement un représentant du réalisme parmi les grands écrivains de cet art - car dans Mimesis (2009) Zola est considéré par Auerbach comme le dernier des grands réalistes français. En plus, pour la deuxième partie de ce travail, on a l'intention de traiter l'émergence de l'impressionnisme artistique en France, et de présenter les concepts et les thèmes qui ont influencé ce mouvement et se présentent dans la construction des récits de Maupassant. Pour le faire, O impressionismo (1962) de Balzi, O impressionismo (1965) de Serullaz, Impressionniste et symboliste devant la presse (1959) de Jacques Lethève, Impressionismo (2010) de Lobstein e autres, mentionnés dans la bibliographie de cette recherche, ont ouvert la voie aux analyses...

It is a systematic literature review, wich aimed to analyze documents, as is the inclusion of the family in Mental Health Services. To do so was based on a literature in the database of the Latin American and Caribbean Health Sciences (LILACS). And the documents were selected from the question which funded the research to evaluate the contribution of scientific research published in journals in the period 2000 to 2011. Data analysis reveals that the government's efforts in having the family as an ally, not a recent phenomenon. But this is a process that depends not only on government, also depends on the professionals involved and of their own families, and other factors. It is concluded that much remains to be done, both in terms of research for the topic, the actions in the reality of such a process

As investigações conduzidas para avaliar novas substâncias para o tratamento da giardíase justificam-se pelo fato dos medicamentos convencionais apresentarem inconvenientes relacionados à toxicidade, à resistência e aos custos. Diante disso, a busca por novas alternativas terapêuticas tem despertado grande interesse, principalmente, entre os extratos de plantas, produtos complexos com diferentes atividades biológicas e farmacológicas. Considerando que nas infecções por Giardia, a diarréia é um dos principais sintomas, tem sido crescente o interesse em se investigar o efeito de extratos de plantas com atividade antidiarréica. Com isso, o presente trabalho foi desenvolvido com o objetivo de avaliar in vitro o efeito do extrato hidroalcoólico da casca da planta Astronium fraxinifolium, espécie típica do Cerrado brasileiro e empregada na medicina popular no tratamento contra inflamações, diarréias e úlceras gástricas. Para este fim, avaliou-se a atividade sobre o crescimento e aderência de trofozoítos de cepa autóctone de Giardia duodenalis isolada e axenizada em Botucatu, São Paulo. Em todos os ensaios, 105 trofozoítos da cepa BTU-11 foram inoculados em tubos contendo 4,5ml de meio TYI-S-33 e 100μl do extrato nas concentrações de 125; 250; 375 e 500 μg/ml. Para avaliar a atividade sobre o crescimento, os parasitas foram incubados com o extrato durante 24, 48 e 72 horas a 37°C. Nos experimentos que verificaram o efeito sobre a aderência, somente os parasitas aderidos às paredes dos tubos foram incubados com o extrato, durante 24 e 48 horas a 37°C. Em cada ensaio, os trofozoítos recuperados foram contados em câmara de Neubauer e a atividade sobre... (Resumo completo, clicar acesso eletrônico abaixo)

A parameter commonly used in investigations of environmental magnetism is the magnetic susceptibility (MS), which is the quantitative measure of the ability of magnetization of a specific material in the presence of an induced magnetic field. The present study aimed to determine the magnetic susceptibility of sediments collected on the continental shelf near the Santos Basin, southeast of the São Sebastião island (25°57.97’S 45°07.81'W), seeking to identify the possible source area of terrigenous sediments and the flow patterns of siliciclastic sediment yield in the area. It was used particle size analysis and contents of organic matter and calcium carbonate to characterize the sediments, besides paleomagnetism parameters. The analyzed material - core NAP61-1 - was collected using the piston corer sampler in 60 meters water depth, recovering 3.98 meters of sediment core. As from experiments, cyclicity was observed in relative abundance between sand and silt, most likely due to rapid and cyclical variations in the depositional environment. In general, the MS values are low, and show that the sand supply (terrigenous material) has a certain consistency, probably having the same origin. More absolute age is still necessary to establish clearly the events marked here

Este trabalho objetivou analisar a qualidade da água de três córregos tributários do rio Bauru, levando em conta a poluição causada por produtos orgânicos e industriais que vinham sendo descartados nos mesmos e as eventuais melhorias conseqüentes das medidas paliativas assumidas pelo DAE-Bauru, mediante a instalação de interceptores-coletores de águas residuárias ao longo Daqueles corpos de água, até que a Estação de Tratamento de Esgotos do município seja construída e se dê início ao seu funcionamento. O monitoramento destes corpos de água durante o período de estiagem e de cheias proposto nesta pesquisa, incluiu investigações sobre as variáveis químicas e físicas de amostras das águas, obtidas mensalmente em 7 pontos de coleta, localizados a montante e a jusante dos pontos de instalação dos emissários, ao longo dos córregos. As amostras de água foram posteriormente analisadas para fossem obtidas informações sobre a eficácia da instalação dos interceptores com relação ao processo de recuperação da saúde dos corpos aquáticos em questão. Os resultados obtidos mostraram que, de um modo geral, as águas de todos os sistemas estudados ainda sofrem impactos, até porque ainda há aquelas que recebem o esgoto descartado “in natura”. No entanto, como ja era esperado, nos pontos de coleta localizados em segmentos dos córregos nos quais os emissários já foram instalados, o impacto ambiental é menor. Mediante a comparação dos resultados obtidos das análises das características físicas e químicas das águas dos sistemas estudados realizadas durante esta investigação com aqueles obtidos nos mesmos corpos de água, em 2007, pudemos observar melhorias da água em alguns dos pontos de coleta

The use of physical characteristics for human identification is known as biometrics. Among the many biometrics traits available, the fingerprint is the most widely used. The fingerprint identification is based on the impression patterns, as the pattern of ridges and minutiae, characteristics of first and second levels respectively. The current identification systems use these two levels of fingerprint features due to the low cost of the sensors. However, the recent advances in sensor technology, became possible to use third level features present within the ridges, such as the perspiration pores. Recent studies show that the use of third-level features can increase security and fraud protection in biometric systems, since they are difficult to reproduce. In addition, recent researches have also focused on multibiometrics recognition due to its many advantages. The goal of this research project was to apply fusion techniques for fingerprint recognition in order to combine minutia, ridges and pore-based methods and, thus, provide more robust biometrics recognition systems, and also to develop an automated fingerprint identification system using these three methods of recognition. We evaluated isotropic-based and adaptive-based automatic pore extraction methods, and the fusion of pore-based method with the identification methods based on minutiae and ridges. The experiments were performed on the public database PolyUHRF and showed a reduction of approximately 16% in the EER compared to the best results obtained by the methods individually

The research addresses the need for detailed geological and geotechnical investigations in pipeline’s design, given the diversity of geological units crossed by these works along its layout, which often extends for hundreds of miles. For its large size, this type of work often goes through different states and regions with very different characteristics in terms of topography, vegetation, geology and geotechnical conditions. For a better use of these investigations in order to avoid unnecessary costs and inefficient results, some authors recommend that steps be taken to study, seeking a progressive detail of the pipeline’s implantation area. The main objective of the study is to describe, analyze and correlate the proposals for geological and geotechnical’s investigation recommended by the authors selected. Nogueira Junior & Marques (1998) suggest that for better effectiveness of geological and geotechnical investigations associated with the deployment of pipelines, different research methods are applied sequentially in five major stages of the building. Rocha et al (2008) recommend that, for the pipeline’s implantation using horizontal directional drilling, investigations are performed in three phases of study, to be developed in coordination with the project stages. For Gelinas & Mathy (2004), when time and budget constraints permit, geotechnical investigations for directional drilling projects for pipelines must be made in four sequential phases. Heinz (2008) suggests that the geotechnical investigations for pipeline’s implantation using horizontal directional drilling at crossings of water bodies are carried out in three successive stages. By the development of research, we could see that all the different proposals recommend studies in sequential phases, starting from a more general scale for a more specific, seeking a progressive understanding of the geological model of the area where you intend to deploy the pipeline

This work aims to understand the ways that have led Brazilian geographers to use the gender category as an analytic element in other to understand the production of space, through the theoretical perspective of Feminist Geographies. Thus, it is important to consider, in the history of geographical science, the theoretical and methodological foundations which enabled the inclusion of gender in researches, since this subject belongs to the field of Anthropology and Sociology and it rarely appears in geographical investigations. It is understood that the gender, as an analytical category of intertwined social relation of space, comprising not only the femininity as well as masculinity and transexualities, analyzed in a relational perspective. However , greater emphasis on the understanding of woman as an agent of space will occur, due to the importance of taking the role of women in building the world out of the hidden of history. Therefore, some works produced in Geography in Brazil will be presented and discussed in order to give visibility on the treatment of space and gender relationship

Due to the new discoveries of oil and gas reservoirs, and also the increasing production of bio-fuels, the brazilian general pipeline system is being vertiginously extended. On the other hand, there is a lack of clear parameters that would allow a better utilization of the geological-geotechnical studies in the process of environmental licensing of pipeline systems. Therefore, this paper presents guidelines that would orientate the environmental licensing procedures to build pipeline systems, and also the geological-geotechnical studies that would support the characterization of the physical context. The method applied in this study consisted in the existing data survey and in their organization, analysis and review. In doing so, there is a well-subsidy integration of the many steps of the pipeline system implementation, the required environmental licenses and the investigation methods of the correlated physical context. As a result, it’s presented a flowchart of the guidelines, detailing the interaction between the environmental licensing, the geological-geotechnical studies and the phases of the pipeline’s project.
