Utilização de um secador solar para desintoxicação da torta de mamona

It´s been motivating motivated by the current rulers as an energy solution the use of the biodiesel as source of energy, that doesn't damage the environment and promotes the development of the areas where the base plant are grown. The process of production of the biodiesel, starting from the castor oil plant and its derivers, generates a known product as castor oil plant pie that has been used as fertilizer. Once disintoxicated, it can serve as animal ration, because it contains high content of proteins, presenting larger joined value. The disintoxication process, can be obtained through the process of drying the pie with the construction and use of models of dryers capable to elevate the temperature of the castor oil plant pie to approximately 60ºC.In this temperature the product tends to eliminate the ricina, with the aid of an aqueous solution of hydroxide of calcium, or still reach higher temperatures to make the disintoxication without a chemical treatment. It was made a bibliographical research about known processes of disintoxication of the castor oil plant pie from the autoclave use to the drying direct exposure to the sun. Starting from the state of the art and identification of the object, it was chosen solar dryers to eliminate the ricina. It was applied two types of solar dryers: the one of solar direct exposure, and the one with concentrador. The castor oil plant pie was separated in samples, with measurement of its initial mass, codified and placed in the dryers. The results were presented in graphs and tables forms, with the values of temperatures noticed. It was noticed the variations of temperature and the relationships analyzed related with the ricina content eliminated from the pie. The analysis of the ricina content was accomplished by Embrapa - Campina Grande, by eletroforese method. The analysis of the result of considering the content of ricina of the samples. It was observed that, we obtained lower rate of ricina in samples that had larger drying time and average value temperature above 60ºC. Comparing with the ones submitted to higher temperatures and in a shorter period of time. It was possible to evaluate the efficiency of the dryers in the desintoxication process of the samples, as well as the type of more appropriate dryer for the drying pie process. Finally, it was concluded that the solar dryer with concentrador presents higher values temperatures than the direct exposure one. So, it´s being more opportune applied in the castor oil plant pie drying process. However, more than one hour for drying time is needed

As influências da psicanálise na educação brasileira no início do século XX

O presente artigo tem por objetivo discutir, a partir de um vértice histórico, a relação entre educação e psicanálise no Brasil. Partindo de um estudo qualitativo, fundamentado na análise bibliográfica relativa à produção psicanalítica dedicada à educação produzida no país nas primeiras décadas do século XX, são discutidas as contribuições da psicanálise na transformação das práticas educacionais. Os resultados indicam que a psicanálise esteve presente na educação de duas formas: inicialmente, pela divulgação de informações teóricas relativas aos conceitos psicanalíticos e às características do desenvolvimento emocional da criança, por intermédio de livros e cursos destinados a educadores, e, posteriormente, através da criação de uma prática de assistência ao escolar com problemas de aprendizagem ou comportamento, desenvolvida em clínicas de orientação infantil, que consistia na avaliação da criança e na orientação de pais e professores. Conclui-se que a psicanálise, enquanto fundamento teórico e prático, forneceu elementos que contribuíram para a sustentação dos pressupostos filosóficos da Escola Nova, que surgiu, a partir da década de 1920, como alternativa ao ensino tradicional.

Matemática Védica no ensino das quatro operações

This paper describes a study on the possibilities of teaching Vedic Mathematics for teaching the four operations. For this various literature sources were consulted considering three main aspects. The first of a historical-cultural, in order to gather information about the Mathematics originated from Vedic civilization, which highlight (Plofker, 2009), (Joseph, 1996), (Bishop, 1999), (Katz, 1998), (Almeida , 2009). This sought to emphasize relationships of the development of this culture with the math involved in the book Vedic Mathematics written by Tirthaji and published in 1965. In this respect the work brings notes on the history of mathematics on the development of mathematics in ancient India. The second aspect was related to teaching mathematics through research activities in the classroom, in this sense, I sought a bibliography to assist in the construction of a proposed activity to teach the four operations, based on the sutras of Vedic Mathematics, but within an investigative approach, assisting in the development of mental calculation strongly stimulated by the Vedic Mathematics Sutras. The authors were adopted (Mendes, 2006, 2009a, 2009b), Bridge (2003). The third aspect considered to search for books on teaching Vedic Mathematics, written by other authors, based on the book by Tirthaji. This revealed Vedic Mathematics textbooks adopted in schools and free courses in the UK, USA and India, all based on the book Vedic Mathematics of Tirthaji. From the bibliographical studies were prepared didactic guidelines and suggested activities for the teacher, to assist in teaching the four operations. The educational product, consisting of Chapters 4 and 5, is the body of the dissertation and consists of didactic guidelines and suggestions for activities that aim to contribute to the teachers who teach initial years of elementary school

Geometrias não-eucludianas como anomalias: implicações para o ensino de geometria e medidas

This present research the aim to show to the reader the Geometry non-Euclidean while anomaly indicating the pedagogical implications and then propose a sequence of activities, divided into three blocks which show the relationship of Euclidean geometry with non-Euclidean, taking the Euclidean with respect to analysis of the anomaly in non-Euclidean. PPGECNM is tied to the line of research of History, Philosophy and Sociology of Science in the Teaching of Natural Sciences and Mathematics. Treat so on Euclid of Alexandria, his most famous work The Elements and moreover, emphasize the Fifth Postulate of Euclid, particularly the difficulties (which lasted several centuries) that mathematicians have to understand him. Until the eighteenth century, three mathematicians: Lobachevsky (1793 - 1856), Bolyai (1775 - 1856) and Gauss (1777-1855) was convinced that this axiom was correct and that there was another geometry (anomalous) as consistent as the Euclid, but that did not adapt into their parameters. It is attributed to the emergence of these three non-Euclidean geometry. For the course methodology we started with some bibliographical definitions about anomalies, after we ve featured so that our definition are better understood by the readers and then only deal geometries non-Euclidean (Hyperbolic Geometry, Spherical Geometry and Taxicab Geometry) confronting them with the Euclidean to analyze the anomalies existing in non-Euclidean geometries and observe its importance to the teaching. After this characterization follows the empirical part of the proposal which consisted the application of three blocks of activities in search of pedagogical implications of anomaly. The first on parallel lines, the second on study of triangles and the third on the shortest distance between two points. These blocks offer a work with basic elements of geometry from a historical and investigative study of geometries non-Euclidean while anomaly so the concept is understood along with it s properties without necessarily be linked to the image of the geometric elements and thus expanding or adapting to other references. For example, the block applied on the second day of activities that provides extend the result of the sum of the internal angles of any triangle, to realize that is not always 180° (only when Euclid is a reference that this conclusion can be drawn)

A ação pedagógica sob a perspectiva de Henri Wallon

The objective is understood to seek subsidies in theory that can guide the construction of an education in the Children's activites, focused on the development aspects of cognitive, affective and motor of the child. It adopts as methodology the bibliographical revision, the intervention, observation and data collect, using as pedagogic resource playing activities in an institution of Infantile Education. The research noted the possibility of action with the concepts proposed by the Wallonian theory, furthermore, the Children's Fitness, using the recreational activities such as teaching resources boost child development. Therefore, concluded that physical education should include Child in the process of teaching-learning the full development of the child.

O mercado imobiliário e a reinvenção da Ribeira, Natal - RN: verticalizar para renovar?

The real estate dynamic originates new spatial forms, which can determine new uses and new places. We tried to analyze this work, the spatial transformations in the Ribeira district, Natal / RN, due to the advancement of the housing market that is gradually transforming the landscape with the introduction of new types of housing, especially by verticalization. The verticalization of the neighborhood occurs almost at once, changing the local landscape. Notwithstanding this process, given the rapid growth of Natal in the last two decades and the strategic location of the neighborhood, it is pertinent to note that, if not the process of vertical integration, perhaps the neighborhood had been at the mercy of other urban interventions and other approach the real estate market. The research used as instruments interviews with actors who work in the property market in the town and representatives of organizations that have implemented major legislation in the area, the Instituto de Patrimônio Histórico e Artístico Nacional (IPHAN) and the Secretaria de Meio Ambiente e Urbanismo (SEMURB) as well as photographs on the area, in order to verify this new configuration that has been consolidated in the district. To support the theoretical discussion, there was a documentary and bibliographical research. In this way, the object of study of this search sees the uniqueness of urban renewal in the district of Ribeira and its relationship with the historic preservation laws and incentives for residential occupation in the neighborhood, especially regarding the vertical building

A Dança na Escola: um sério problema a ser resolvido

Pretendemos abordar os aspectos relacionados à Dança na Escola e pensarmos sobre uma formação continuada, a fim de discutir e refletir a elaboração de propostas de capacitação em Dança voltadas aos professores de Educação Física, principalmente no interior do Estado de São Paulo. Analisaremos a formação inicial dos professores, objetivos, conteúdos e possibilidades de aplicação da Dança no contexto educacional. Apesar do aumento das pesquisas em relação ao ensino da Dança na Escola, falta um espaço adequado e professores comprometidos com um trabalho sério, consciente e crítico, pois a hegemonia do esporte se encontra muito arraigada na cultura escolar. Uma forma de amenizar esse problema seriam cursos de capacitação, de forma permanente, voltados aos conteúdos de Dança, a fim de que esses professores possam ter vivências em práticas dançantes embasadas em uma fundamentação teórica para, assim, discutir, analisar e refletir a melhor maneira de trabalhar esta arte no âmbito escolar.

O Partido Comunista (1922-1962): lugar de memória, espaço de disputa

This work studies the dispute by Party Communist s memory in Brazil during and after division which it resulted in the appearance of two parties entitled communists, in the brazilian political context, in the final of the fifties and beginning of the sixties: the Brazilian Communist Party (in Portuguese, Partido Comunista Brasileiro) and the Communist Party of Brazil (in portuguese, Partido Comunista do Brasil). Along of yours three chapters, the author tries to answer some questions as: what were the elements which constituted the Communist Party s memory, in the period from 1922 to 1956? At which moment did this memory pass to be fiercely contested? Who and which documents reveal this? How did it happen the dispute by this memory? The approach to topic consider which the production of memory by Communist Party and the dispute for your possession by communists of PCB and of PCdoB happened in scope of national reality and of party, spaces notions understand from concept of memory developed for authors as Halbwachs, Le Goff, Pollack and Pierre Nora. To explain the objectives of historical research it has used as methodology the exam and the interpretation of documentary and bibliographical sources, with priority for the party s documents then it was depicted a collective interpretation about the events considered more importants. The sites of Partido Comunista do Brasil (www.pcdob.org.br or vermelho.org.br) and of Partido Popular Socialista (www.pps.org.br) also went consulted

Psicologia e profissão: neurose profissional e a atuação do psicólogo organizacional frente à questão

Este artigo pretende fazer um levantamento bibliográfico sobre a neurose profissional, cujos sintomas são entendidos como a expressão simbólica de um conflito psíquico que se desenvolve a partir de uma situação organizacional ou profissional determinada. O diagnóstico é formado a partir das queixas mencionadas, da história de trabalho e da análise da situação de trabalho atual. Entende-se que condições estressantes de trabalho, associadas ao contexto social de desemprego e competitividade, contribuem para o aparecimento de doenças mentais como a neurose profissional. As formas de tratamento para essa doença, além da psicoterapia individual, envolvem a ação integrada de uma equipe multiprofissional capacitada para lidar com o sofrimento psíquico do trabalhador e com os aspectos sociais e de intervenção nos ambientes de trabalho. Ressalta-se a carência de literatura sobre o tema estudado e a importância de se ampliar a discussão sobre os fatores de risco no trabalho, os determinantes psíquicos para o desenvolvimento da neurose profissional e o papel do psicólogo no contexto de prevenção e promoção da saúde mental.

A presença da produção científica em psicologia na formação de psicólogos do Rio Grande do Norte

The present research aimed to analyze the presence of national scientific production in undergraduate studies in Psychology of Rio Grande do Norte. Therefore, the bibliographical references contained in education plan of subjects linked to the common center of the courses, which were taught in 2011 in three Psychology courses of the state, were focused. The analysis of the material was based on bibliographical and contextual aspects of the production, such as year, nationality, type of material, authorship (including the link of authors to PPGs), structuring axis of the subject in which it was mentioned, among others. The results showed that the national production is predominant in all courses, and they are, mostly, originated from PPGs of Psychology. Among these, the publications resulted from programs in Southwest, with emphasis to PUC-SP, are recent (mostly from 2000s) and they are predominantly composed by books (organizations and full texts). Regarding the distribution of Psychology PPGs production by the structuring axes, it is observed that it surpasses the foreign production only in axis C (procedures of scientific investigation and professional practice) and axis F (professional practices). Accordingly, it is concluded that Psychology production is found in graduation, sharing space with foreign publications and from other areas of knowledge. On the one hand, this is positive, by taking into account the importance of several foreign works and from other fields to build the knowledge in Psychology; on the other hand, it shows that the production from this area is inserted in graduation in a less significant way than its growth, which points out the existence of gaps in the development of some investigative domains from national Psychology

Precarização do trabalho no setor de supermercados : um estudo de caso com trabalhadores em Natal

Precarization of work, process situated historically after the third Industrial Revolution, express itself as one of the faces of changes in production modus and working conditions. The present study aims to identify the process of work precarization in supermarket sector in Natal municipality. The choice for this sector and professional category is based on low investment in studies on the commercial sector and on technological and administrative transformations that supermarkets have implemented. After a bibliographical review, ten indicators of precarization were chosen which permitted to set up a schedule to interviews and its application to employees of two supermarkets (local companies) in Natal area. The following working functions were chosen to participate in the survey: cashier, display assistant (shelf-stacker) and attendants (N=6). From the interviews we developed an analysis of categorical contents in order to identify the presence of precarization indicators. Categorizations allowed us to identify five major themes: work categorization; work meaning: its attributes; work meaning: work centrality; comments on the employment of apprentices or trainees; and transversal work contents. Such themes contents express or not the presence of precarization process at supermarket sector in Natal area. Precarious work is identified in participants speech when they refer to the employees decreasing power in salaries negotiation between them and employers that institute the precarious work conditions

A contextualização e a interdisplinaridade no ensino de Química: uma analise de livros didáticos ACIDO-BASE e das propostas pedagógicas realizadas pelos docentes diante da temática

Nowadays, chemistry contents taught in high school continue to be presented in a fragmented and decontextualized manner by the teachers and the textbooks. Even though it is known that contextualization and interdisciplinary exchange play an important role in the process of Chemistry teaching/learning. Therefore, the present study aims at enlightening the importance of these methodological foundations in the learning of chemistry. The data acquisition about the subject Contextualization and Interdisciplinary Exchange involved in Chemistry Teaching was developed through bibliographical researches on chemistry textbooks, which focused on the analysis of the topics acid and base , since it is a theme studied throughout all three years of high school. The present study also developed questionnaires which were applied to analyze to what extent chemistry teachers are working in a contextualized and interdisciplinary manner throughout the process of Chemistry teaching/learning. The results obtained in the researches show that a contextualized and interdisciplinary teaching contributes to a more meaningful acquisition of chemistry knowledge, in a dynamic and interactive way, but there are still many roadblocks towards the achievement of this kind of Chemistry teaching/learning process

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

Violência nas escolas: Um novo olhar ante as relações sociais

The most varied ways of manifestation of the violence phenomenon in the contemporary society are each time more found in the media spaces and among society discussions. It makes think about procedures to be taken before the growth and new outbreaks of such phenomenon. The violences manifestations in schools reveal themselves as a reflection of what happens in the scope of social violence. Its dynamics originates in society and reflects itself in scholl, that is, the violences in schools combine internal and external elements to school enviroment of many fields and spheres of which the individuals participate. To reflect about the violences in the schools requires, over all, to make a bridge with the categories: youth and violence. Violences in schools: A new look to the social relations, is a Ms. Sc. Dissertation that has as main objective: to analyze the main existing forms of violence in the school space. For its achievement, it was made a bibliographical survey, questionnaires application (annexed) and observation. Thus, this research articulated the two approaches: qualitative and quantitative. The questionnaires application happened in a state school of the Natal city and amongst yhe criteria for this choice there was the fact of the school had more than 500 pupils, to be located on a strategical place of the city, providing a subjects heterogeneity to be researched, deyond the limitations of available resources financial and material and the available time for the research accomplishment. The scool congregates objective conditions, specifically in what concerns the criteria previously defined: age range, socioenomical level and number of pupils. Amongst the main results obtained, it can be detached that the violence is a phenomenon seen, for the great majority of the research subjects, as a phenomenon connected to the most visible violence forms: the agressions. And a question always present in the public education institutions: infrastructures precariousness, high scool evasion índex and vulnerability among the pupils that makes possible to the pupil to see school as an home extension. Such dissertation concludes that the phenomenon of the violence in scools demands and requires of the most varied subjects involved in the processes na understanding of its determinants so that thus, one can intervene in such phenomenon that does not restrains itself to the physical acts of aggression, but that it is, over all, on a non respecting the different
