Investigação das propriedades fotocatalíticas de filmes finos de TiO2 depositados por solução orgânica de citratos

Nowadays environmental pollution can be identified as a major problem in developed and developing countries. This is the result of several factors, such as inappropriate use of natural resources, inficiente legislation and not ecological awareness. Moreover, many other procedures as incorrect use of chemicals still contributed to the worsening of the problem. In this work, we develop a working with the environmental ideals, aiming to contribute to the decomposition of organic material through decomposition of rhodamine in TiO2 thin films on a silicon substrate. The degradation performance was monitored with the aid of techniques such as atomic force microscopy, transmission electron microscopy, field emission gun scanning electron microscopy, Fourier transform spectroscopy, thermal and photocatalytic analyses

Alfabetização: o texto e o contexto

This paper is the result of a research about literacy concept from official documents, dictionaries and linguists. As an expansion of literacy concept was observed through last century, this investigation searched for an opposite way, in other words, a contraction of the literacy concept in order to clarify its nature and this way to be the starting point for literacy teachers. The best way to literacy happens was also part of the research, then the text was considered like that, since it is a real communicative situation. Besides it should be a meaning system which can be accessed again any time. It would include many kinds of texts – oral or written – as long as they were recorded somehow. The best text form was investigated as well, in other words, the best speech genre for teaching literacy, once there are important elements which should be considered during the literacy acquisition, such as the encouragement to read and to think about the correct writing of the words. In the end, considerations were made concerning the literacy teacher‘s awareness about the context change when the text is used in a scholar context and about the skills acquired by the students which should be transported to other texts in varied contexts

O discurso do uso de animais nas pesquisas de Educação Física

It is possible in many countries, perhaps all, there is business groups of pharmaceuticals industry, cosmetics together with the universities that use animals in scientific research and testing for the creation of new products and medicines. Currently is growing discussion about standards and criteria for the use of these animals (guinea pigs) and also increases the number of debates on ethical issues in research with animal models. This research seeks to portray the reality of the use of animals in scientific research academic at the University, specifically to research in physical education, as it has used animals in the areas of Physiology of Sport and Physical Activity, Nutrition for Athletes, among others. Initially is shown the pre-reflection, exposing the laws governing the subject, treating the animal experimentation with regard to its history and the issues of speciesism and the methodological mistake. It reveals what it is and as is the use of animals in education and the inability of the student to change that reality, to refuse to participate in the cruel activity, and even they are aware of their rights as in the case of the withdrawal of consciousness. Presents researchers and universities not use animals and ends the pre-debate showing Who is really the most animal research at the university by providing alternatives for them. We conducted a literature survey on animal experimentation, research universities, and alternative methods. The following is the phenomenon in understanding and awareness of the researchers who use animals in their research, conducting a phenomenological analysis of his speeches, revealing the meanings of their animal research. The focus of this study is, therefore, the analysis of discourses of researchers who carried out research using animal experiments (guinea pigs). The phenomenon of understanding of the researchers about their research is made clear... (Complete abstract click ectronic access below)

No resumo de um só dia: tempo e memória em O burrinho pedrês de Gumarães Rosa

Memory, the ability of keeping and remembering past states of consciousness and everything that could be associated with them, is one of the human properties responsible for the construction of experience, knowledge and preservation of individual’s identity. However, recalling is also the way we keep relationships with time, factor that is essential and inherent to our existence and responsible for the fact that we have memory. As for the narrative, as for life, time is a prime category, because it is in time that narrated or experienced events happen. This relationship between time and memory is remarkable in “O burrinho pedrês”, Guimarães Rosa’s short story present in his debut book, Sagarana. In this story, we can notice, generally, the characters use memory as a way to return to the past, evoking, consciously or unconsciously, the experience and its result, the wisdom, to help on the understanding of present situations. So, this research has as objective to analyze how time and memory relate and become indispensable to the development of the narrative and to the construction of the other categories - character, narrator and space. The theoretical foundation is based on studies clustered in three dimensions: a) theoretical essays about Guimarães Rosa’s work in general and the particular short story b) philosophical and/or psychological propositions about memory and time, and c) propositions about the mentioned categories of narrative

Traços míticos e arquetípicos em personagens femininas de Guimarães Rosa

Dans l‟“A historia de Lina et Lélio, le troisième récit de Corpo de baile, l‟oeuvre de Guimarães Rosa, Lélio arrive à la ferme Pinhém à la recherche de l'amour, de la paix d'esprit et de l'auto-connaissance, mais il n'a pas la claire conscience de cela. Dans cette trajectoire, on peut voir le poids des femmes: bien que Lélio soit le protagoniste de cette histoire, les personnages féminins présentent des différents profils et sont construites sur des aspects mythiques et archétypiques, qui ont des influences directes sur le destin de ce personnage masculin. On cherche, donc, comprendre comment l‟auteur fait la caractérisation mythique et archétypique des personnages féminins, voir l'influence de celles-ci sur la suite du récit ainsi que dans la construction du protagoniste. De la même façon, on veut vérifier comment les autres catégories du récit – telles que le temps, l'espace, le narrateur et la focalisation – peuvent contribuer à cette caractérisation. Cette recherche est développée à travers des lectures, des notes et des discussions autour du corpus, en s'appuyant sur une base théorique déterminée en trois dimensions : a) des essais critiques à propos de l‟oeuvre de l'auteur, en particulier au sujet en cause, comme celui dans l‟A raiz da alma, de Heloisa Vilhena Araujo, b) des études sur le mythe, comme celles de Ernest Cassirer, dans le Linguagem e mito et Antropologia filosófica, et les propositions de Meletínski dans l‟A poética do mito et dans l‟Os arquétipos literários et, encore, c) des textes théoriques sur les catégories du récit, présentées dans le Dicionário de teoria da narrativa, de Reis et Lopes, et des études sur l'espace, comme celui d'Antonio Dimas, Espaço e romance, et sur le temps, de Benedito Nunes, O tempo na narrativa. On observe que, dans la construction des personnages féminins... (Résumé complet accès électronique ci - dessous)

A importância da linguagem do educador no processo de construção da autonomia moral da criança pré-escolar

This paper demonstrates that in every society there are limits and these are imposed on its members. However, the awareness and the determination of theses limits are necessarily how they are transmitted by the educator to the learners. Its purpose is to show that autonomous, critical and cooperative individuals are result of the form they were educated and instructed in the classroom. Schools and educators should be concerned with the education of individuals able to reflect, discuss and solve the social and moral conflicts through dialogue, exposition of ideas, suggesting alternatives and the preparation and reworking of the principles and norms that govern society. The goal of this study is identify and highlight the importance of educator language in conflict resolution, its consequences and effects on the process of building the moral autonomy of children in preschool, as well as discussing, in theory the two types of language, evaluative and descriptive. In the same way, show the importance of descriptive language on the construction process from moral autonomy of learner. Several existing research about the chosen subject led to face this challenge, deepening the study to show that and educational system focused on cooperative environment, where teacher actions encourage social interaction, giving the student opportunity to talk, argue and present his thoughts, causes a significant development toward the construction of moral autonomy on the learner

Práticas corporais complementares: um estudo sobre a antiginástica

The concept of physical education emerged in the XIX century through the European gymnastic methods, initially for the purpose of asserting the sovereignty of the nationality of countries, by means of exaltation of patriotism of the masses and the physical preparation for military wars. Nowadays, the cult of the ideal body has changed, becoming the unceasing desire within each society, according to its characteristics of established standards, most of the time denying the genetic determinations of each ethnicity. This social phenomenon has generated openness and encouragement to the fitness market on the rise, eager in supporting the aspirations of the cult of the body”, representing the huge seek of the idea of a healthy body and an aesthetic appearance acceptable in today's society. Parallel to this, the Body Awareness Gymnastics, also known as Technical or Complementary Practices, were introduced in Brazil in the 70s, presenting as main themes the body awareness, the mind-body relationship, and against the ideals of body training. According to authors, the pioneering technique of the movements of alternative practices in Brazil was Antiginástica of Thérèse Bertherat. Therefore, this study aims to harmonize the complementary body practices of the physical education area through literature review of published works by the author Thérèse Bertherat, entitled The body has its reasons, The body communication system, Stations of the body, The Tiger´s Den and When the body is consent. The work also includes the contribution of a particular reading of the researcher, from the experiences of the practices carried out in order to enrich the reporting work through their records, the results obtained from the experiential process

A construção da autonomia numa perspectiva piagetiana: contribuições para a Educação Infantil

This paper aims at discussion the construction of autonomy of cognitive development and child morality, according to the Piagetian approach view of the influence of socio-moral classroom in kindergarten. It is known that education is a very important part of participation in relation to the development of autonomy by the child, especially when it comes to kindergarten who becomes responsible for performing the initial encouragement of this ability, respecting the phase cognitive development in which the child is. We focus, therefore, the need for education and teaching activities that enable this construction offering little opportunity to exercise and build their first signs of autonomy. For their achievement, in addition to literature, which has been supported by theoretical studies of Jean Piaget, we chose a field research where we look, from the interview and observation, investigate the socio-moral environment of a room class of a school Kindergarten, highlighting the important opportunities for the exercise of autonomy for the children, amid the routine of the group. The interview was focused on the pursuit of basic knowledge of the educator on the subject, as well as what would be aware of the role of preschool in the process of moral development and about their own role as an educator this mode of education. Since the remark was directed at the teacher's procedures against the encouragement of social and moral ability, focusing mainly on interpersonal relationships in the classroom. Our classroom has proved to be a cooperative environment and therefore we emphasize the importance of the teacher's conduct that permeated the day-to-day classroom and encouraged to start building this skill by the student. The main objective of this study therefore was to investigate the possibilities and outcomes that have a school experience for the development of autonomy for children

Poluição atmosférica e paisagem urbana no município de São Paulo

This paper proposes an analysis of two major polluting elements of the atmosphere of São Paulo city, carbon monoxide (CO) and sulfur dioxide (SO2). This study was performed through analysis of data on the quality of air, by means of published reports and records obtained by experiment using measuring rate monitor for CO2. Atmospheric data were collected and sorted. From this work it was possible to identify the concentration of carbon dioxide in the center of São Paulo on September 14, 2012 using the infrared gas analyzer (IRGA). From the ratios of carbon monoxide and sulfur dioxide spatially analyzed could identify major emitters by comparing records of pollutants and their origin. The analysis makes it possible to map the intensity of air pollution in urban areas, identifying the polluting elements, their issuers and thereby contributes to the current understanding of atmospheric features, bringing a geographical spatial analysis of air pollutants in São Paulo, contributing to awareness of vulnerabilities, enabling a useful tool for planning and maintenance of the urban environment related public policies

Análise das alterações temporais dos fragmentos de vegetação no centro experimental do Instituto Agronômico, Campinas, utilizando técnicas de sensoriamento remoto e geoprocessamento

O presente estudo tem como objetivo principal realizar um levantamento temporal das áreas de vegetação no Centro Experimental de Campinas (CEC), uma fazenda de propriedade do Instituto Agronômico (IAC), a partir de técnicas de geoprocessamento e fotointerpretação. O local de estudo situa-se no município de Campinas - SP, e a área em questão foi escolhida por estar situada dentro de uma propriedade do estado e por apresentar uma grande mudança histórica no que diz respeito à vegetação. Também por que, apesar de ser um centro de experimentação agrícola, esse estudo demonstrara como num intervalo de quarenta anos a consciência ecológica muda radicalmente dentro do Centro. Para a realização deste trabalho, foram utilizadas fotografias aéreas digitais da fazenda dos vôos referentes aos anos de 1964, 1972 e 2002, todas de propriedade do acervo do Laboratório de Geoprocessamento do Centro de Conservação dos Solos do IAC. Alem da foto de satélite da fazenda obtida no software Google Earth, com data de 2006. Analisando imagens e mapas, observou-se como a área vegetada aumentou no Centro Experimental de Campinas nesse intervalo de quarenta e dois anos, passando de 7,55% (52.383 ha) em 1964 para 34,13% (236,497 ha) da área total do centro em 2006. Também pode-se ver que hoje há uma preocupação muito grande com a manutenção e conservação dessas matas.
