Materials and Methods: Thirty six Wistar rats were used in the study, and four of these were blood donors to obtain the PRP and the PRF. The Injuries were made on the sciatic nerve from the left paw with 10mm long gap and they were repaired with one of the four treatments: Autologous nerve grafts (ANG); tubulization with saline solution (TS); tubulization with PRP; tubulization with PRF. Walking track analysis were performed at pre-operative period, 30, 60 and 90 days after surgery. On the 90 postoperative day, the rats were euthanized and histomorphometric analysis were made measuring the fiber diameter, axonal diameter and the myelin sheath thickness. Results: On 90 days post-operative, the ANG, PRF and PRP groups presented a significant functional improvement in relation to the TS group (p = 0.000), which showed functional deficit. On the histomorpometric test, the ANG group presented a better structural organization, with a regular distribution among the myelinated fibers, and little conjunctive tissue between the fibers. The TS, PRP and PRF groups had a larger endoneural tissue between the nerve fibers and presented degenerative process. The ANG group achieved a larger nerve fiber diameter at the proximal segment while comparing with the TS (p = 0.037), and also comparing with the PRF (p = 0.001) and the PRP (p = 0.002) while analyzing the medial segments. About the axonal diameter and the myelin sheath thickness, no statistical significant difference has been found between the groups. Conclusion: This research data suggests that PRP and PRF have positive effects on functional nerve recovery, presenting results similar to the ANG group. However, the PRP and PRF don t achieve a significant improvement on the histomorphometric analysis. / Objetivo: Avaliar o efeito do uso de Plasma rico em plaquetas (PRP) e de Plaqueta rica em fibrina (PRF) no reparo de nervos perif?ricos, comparando com os resultados do padr?o-ouro (enxerto aut?logo) e com grupo controle (solu??o salina). Materiais e M?todos: Trinta e seis ratos Wistar foram utilizados no estudo, sendo quatro ratos utilizados apenas como doadores de sangue para obten??o de PRP e PRF. Foram criadas les?es de 10mm nos nervos ci?ticos da pata esquerda dos ratos, e estas foram reparadas com um dos 4 tipos de tratamentos: enxerto aut?logo (AE); tubuliza??o com solu??o salina (TS); tubuliza??o com PRP; tubuliza??o com PRF. Foram realizados Testes de marcha no per?odo pr?-operat?rio, 30, 60 e 90 dias p?s-operat?rios. Ap?s 90 dias, os ratos foram eutan?siados e foram realizadas an?lises histomorfom?tricas avaliando di?metro das fibras, di?metro axonal e espessura de bainha de mielina. Resultados: Com 90 dias p?s-operat?rios, os grupos AE, PRF e PRP demonstraram uma melhora funcional significativa em rela??o ao grupo TS (p = 0,000), que continuou apresentando d?ficit na marcha. Na histomorfometria, o grupo AE apresentou uma melhor organiza??o estrutural, com distribui??o regular das fibras mielinizadas, com pouco tecido conjuntivo entre as fibras. Os grupos TS, PRP e PRF demonstraram maior espa?o endoneural entre as fibras nervosas e a presen?a de processos degenerativos. O grupo AE demonstrou maior di?metro de fibra nervosa no segmento proximal quando comparado ao grupo TS (p = 0,037), e tamb?m apresentou maior di?metro de fibra em rela??o ao grupo PRF (P = 0,001) e PRP (P = 0,002), quando comparados os segmentos medianos. Quanto ao di?metro axonal e espessura da bainha de mielina, n?o foram encontradas diferen?as estatisticamente significativas entre nenhum dos grupos. Conclus?o: Os dados deste estudo sugerem que tanto o PRP quando o PRF possuem efeito positivo na recupera??o funcional nervosa, apresentando resultados funcionais similares aos encontrados pelo grupo AE. Por?m, n?o apresentam melhora significativa nas an?lises histomorfom?tricas.

The collective of women was expanding and gained the status of National Gender Sector, responsible for formulating and systematizing discussions regarding the situation of women in society and in the MST, so their publications express theoretically the demands and aspirations of women of the Movement. On the other hand, in their daily lives, women Landless also interpret experienced gender relations within the MST, making it important to listen to them. In the first chapter we present three approaches to thinking about women's issue: equality, difference and autonomy; we assume the theory of recognition of Axel Honneth as interpretive lens investigated reality. The second chapter is dedicated to the MST Gender Sector, its appearance and the way it discusses the asymmetries between the genders, evidenced in seven publications between 1988 and 2015. In our third chapter we analyze the interviews with women Landless, articulating their experiences with the principles of autonomy and recognition, and its denial, disrespect. In the final considerations we reflect on these two forms of women's struggle expression: one theoretical and one practical. / J? nos primeiros anos de funda??o do MST, as mulheres se organizaram em um coletivo para reivindicar sua participa??o pol?tica na luta pela reforma agr?ria. O coletivo de mulheres foi se expandindo e ganhou o status de Setor Nacional de G?nero, respons?vel por formular e sistematizar as discuss?es referentes ? situa??o das mulheres na sociedade e no MST, portanto, suas publica??es expressam teoricamente as demandas e anseios das mulheres do Movimento. Por outro lado, em seu cotidiano, as mulheres Sem Terra tamb?m interpretam as rela??es de g?nero vivenciadas dentro do MST, tornando-se fundamental ouvi-las. No primeiro cap?tulo apresentamos tr?s abordagens para pensar a quest?o feminina: igualdade, diferen?a e autonomia; assumimos a teoria do reconhecimento de Axel Honneth como lente interpretativa da realidade investigada. O segundo cap?tulo ? dedicado ao Setor de G?nero do MST, seu surgimento e a forma como problematiza as assimetrias entre os g?neros, evidenciada em sete publica??es entre 1988 e 2015. Em nosso terceiro cap?tulo analisamos as entrevistas com as mulheres Sem Terra, articulando suas viv?ncias com os princ?pios de autonomia e reconhecimento, e com sua nega??o, o desrespeito. Nas considera??es finais refletimos sobre essas duas formas de express?o da luta das mulheres: uma te?rica e uma pr?tica.

Pesquisa do Estado do Rio Grande do Sul - FAPERGS / The theaching of Zoology in Basic Education often occurs with a descriptive and not very attractive approach for children and adolescents. The objective of this research is to analyze how the use of super heroes in teaching of animals which belong to the group of arthropods can be effective with students of the 7th grade of elementary school. Through a work project, a series of activities have been proposed to the research subjects so they could identify their preconceptions about these animals while they were studying new concepts regarding this zoological group. Each student created a super hero based on an arthropod, as well as a worksheet which described their origins and skills. The development of a story where this hero participates solving any problematic situation was the last assignment performed. Eight characters were selected, and their stories were submitted to Textual Analysis Discourse (MORAES AND GALIAZZI, 2007). After the establishment of meaning units, four categories emerged: Context, Problematic Situation, Characters and Reflections / Constructed knowledge. The fourth category is an identification of what was most outstanding in the students`s writing and can be an indicator of a (re) construction of knowledge. We can identify some aspects of the ecology of some arthropods in the texts, such as their appearance and anatomy in the drawings, eating habits characteristics and relations that these animals may have with other species. The analyzed stories confirm that important biological issues, such as waste management and the issue of genetically modified beings, were worked by students. This study, in a different way, reveals to be also relevant to the development of students' creativity. / O ensino de Zoologia na Educa??o B?sica, frequentemente, ocorre com um enfoque descritivo e n?o muito atrativo para crian?as e adolescentes. O objetivo da pesquisa apresentada nesta disserta??o ? analisar a efic?cia da utiliza??o da figura de super-her?is no ensino dos animais do grupo dos artr?podes com estudantes do 7? ano do Ensino Fundamental. Por meio de um projeto de trabalho, uma s?rie de atividades foram propostas para os sujeitos da pesquisa, a fim de que pudessem identificar suas concep??es pr?vias sobre esses animais enquanto estudavam novos conceitos sobre esse grupo zool?gico. Cada estudante criou um super-her?i baseado em um artr?pode, bem como uma ficha onde suas origens e habilidades foram descritas. A ?ltima tarefa realizada foi a elabora??o de uma hist?ria na qual esse her?i participa resolvendo alguma situa??o-problema. Foram selecionados oito personagens e suas respectivas hist?rias, sendo que estas ?ltimas foram submetidas ? An?lise Textual Discursiva (MORAES E GALIAZZI, 2007). Ap?s o estabelecimento das unidades de significado, quatro categorias emergiram: Contexto, Situa??o-Problema, Personagens e Reflex?es/Conhecimentos Constru?dos. A quarta categoria representa uma identifica??o do que foi marcante na escrita dos estudantes, podendo ser um indicador de uma (re)constru??o de conhecimento. Podemos identificar alguns aspectos da ecologia de alguns artr?podes nos textos, como a apar?ncia e a anatomia dos desenhos, caracter?sticas do seu modo alimentar e rela??es que esses animais podem apresentar com outras esp?cies. As hist?rias analisadas confirmam que quest?es biol?gicas importantes, como o gerenciamento do lixo e a tem?tica de seres geneticamente modificados foram trabalhadas pelos estudantes. Este estudo, de forma diferenciada, mostrou-se relevante tamb?m para o desenvolvimento da criatividade dos estudantes.

This way the main goal of this research was to understand the evolution of the early year?s teachers' ideas about knowledge of Astronomy area, Science Nature, learning and teaching. For that, initially, we have developed a pilot course in extension mode in the extreme south of the Rio Grande do Sul State, which was attended by 10 teachers of Basic Education, totaling 20h course. After analyzing the data obtained in this pilot course, we prepared the course extension and realized new offering of the course, but only for teachers in the early years of elementary school. Thus they participated in the extension course 6 teachers working in public schools in the western region of Parana State, totaling 40 hours of course. The extension course had as a reference the proposed didactic models for curriculum design Research and School Renewal (RSR) and also the dialectic-didactic method, from which it was constructed a course based on the constructivist perspective and guided the following Problems Practical Professionals (PPP): "What are the students 'ideas on topics of Astronomy?", "How to investigate the students' ideas about topics of astronomy?" "What activities can help students' ideas on topics of Astronomy?" And "How to design and develop a teaching unit of Astronomy to the early years of elementary school??. The methodology used for data analysis was Textual Analysis Discourse (TAD), built from the transcript of the teacher diary and researcher of the meetings recorded in audio and also the material produced by teachers over the Extension Course meetings. From the TAD emerged last five categories: 1. ideas of students about astronomy: knowing your questions and insights about what they learn at school; 2. Views of teachers about Astronomy: knowing your questions and your thoughts on what they teach; 3. learning levels built on a concept from research on astronomy activities; 4. Pedagogical applications of the use of the students 'ideas in the classroom: a reflection on the own practice and 5. Evolution of teachers? ideas about the students? ideas. At the end of the analysis we identified that the development of teachers occurred especially in their conception of the astronomy and on the ideas of the students. According to the transition hypothesis developed for this research, teachers evolved from an initial level, where there is recognition of the students' ideas, but there is no use of these ideas in the classroom, to an intermediate level, where teachers know the ideas of their students and include those ideas in their classes, but still no systematic way. Similarly, we conclude that when teachers are learning a new concept, as in the case of astronomy topics, and identify their own ideas on them, they become more sensitive to understand the ideas of their students. In addition, a continuing education course in the curriculum principles guided RSR enables teachers to reflect about their own practice in the classroom. We understand that this is the way so that we can conquer the long awaited change in education, in order to make the school a place where children can, in fact, build new knowledge about the world, and in the case of Astronomy, about the Universe. / De acordo com pesquisas da ?rea do ensino de Astronomia, muitas vezes, os conceitos que os professores dos anos iniciais ensinam nas suas aulas de ci?ncias das s?ries nas quais trabalham, prov?m de sua pr?pria forma??o escolar. Dessa forma, o objetivo central desta investiga??o foi o de compreender a evolu??o das ideias de professores dos anos iniciais sobre conhecimentos da ?rea da Astronomia, da natureza da ci?ncia, da aprendizagem e do ensino. Para isso, inicialmente, desenvolvemos um curso piloto, na modalidade de extens?o no extremo sul do Estado do Rio Grande do Sul, no qual participaram 10 professores da Educa??o B?sica, num total de 20h de curso. Ap?s a an?lise dos dados obtidos neste curso piloto, reelaboramos o curso de extens?o e realizamos nova oferta do curso, por?m somente para professores dos anos iniciais do Ensino Fundamental. Assim, participaram do curso de extens?o 6 professoras atuantes em escolas p?blicas municipais, na regi?o oeste do Estado do Paran?, totalizando 40h de curso. O curso de extens?o teve como refer?ncia os modelos did?ticos propostos pelo projeto curricular Investiga??o e Renova??o Escolar (IRES) e tamb?m o M?todo Dial?tico-Did?tico, a partir dos quais se construiu um curso baseado na perspectiva construtivista e pautado nos seguintes Problemas Pr?tico Profissionais (PPP): ?Quais as ideias dos alunos sobre temas de Astronomia??, ?Como investigar as ideias dos alunos sobre temas de Astronomia??, ?Que atividades podem favorecer a evolu??o das ideias dos alunos sobre temas de Astronomia??, e, ?Como estruturar e desenvolver uma unidade did?tica de Astronomia para os anos iniciais do Ensino Fundamental??. A metodologia utilizada para an?lise dos dados foi a An?lise Textual Discursiva (ATD), constru?da a partir da transcri??o dos di?rios dos professores e da pesquisadora, dos encontros gravados em ?udio e tamb?m do material produzido pelos professores ao longo dos encontros do Curso de Extens?o. A partir da ATD emergiram cinco categorias finais: 1. Ideias dos alunos sobre Astronomia: conhecendo suas d?vidas e compreens?es acerca do que aprendem na escola; 2. Ideias das professoras sobre Astronomia: conhecendo suas perguntas e suas reflex?es sobre o que ensinam; 3. N?veis de aprendizagem constru?dos sobre um conceito a partir de atividades de investiga??o sobre Astronomia; 4. Aplica??es pedag?gicas do uso das ideias dos alunos em sala de aula: uma reflex?o sobre a pr?pria pr?tica e 5. Evolu??o das ideias dos professores sobre as ideias dos alunos. Ao final das an?lises identificamos que a evolu??o dos professores ocorreu especialmente em suas concep??es sobre a Astronomia e sobre as ideias dos alunos. De acordo com a hip?tese de transi??o elaborada para esta investiga??o, os professores evolu?ram de um n?vel inicial, no qual h? reconhecimento das ideias dos alunos, por?m n?o h? utiliza??o dessas ideias em sala de aula, para um n?vel intermedi?rio, no qual os professores conhecem as ideias de seus alunos e incluem essas ideias em suas aulas, por?m, ainda de modo n?o sistem?tico. Da mesma forma, conclu?mos que, quando os professores est?o aprendendo um conceito novo, como no caso dos temas de Astronomia, e identificam suas pr?prias ideias sobre eles, tornam-se mais sens?veis a compreender as ideias de seus alunos. Al?m disso, um curso de forma??o continuada pautado nos princ?pios curriculares do IRES possibilita aos professores refletirem sobre sua pr?pria pr?tica em sala de aula. Entendemos que esse seja o caminho para que possamos conquistar a t?o sonhada transforma??o no ensino, a fim de tornar a escola um lugar em que as crian?as possam, de fato, construir conhecimentos novos sobre o mundo, e, no caso da Astronomia, sobre o universo.

In addition, it seeks to understand how the production of truth is done in this system of juvenile justice. The focus of the analysis relies on the exercise of power and resistance by the social actors in the hearings, trying to understand how the dimensions of ethics and the fluidity of the ?victim? category by the actors allow to access the characteristics of the juvenile justice operation. Through the entry in the field journal and systematic observation of the Porto Alegre juvenile justice hearings, it was possible to note that the production of truth happens as of the interactions between the actors in the hearings through the exercise of the power by the legal agents and of the resistance by the adolescents accused and their relatives. The study shows that the performance of these actors is oriented by opposed ethics confronting and reconciling each other and by a double perception of the legal agents and of State of the ?victim? figure associated with the accused adolescent. The ethics, which conducts the acting of the legal agents in the exercise of power, aims to internalize in the adolescents the model of life assumed as healthy, good and correct by those professionals. The ethics, which conducts the performances of resistance of the adolescents and their relatives to the power exercised by the legal agents, are based on the belief that the physical violence and practice of illegal acts are tools of social mediation able to grant them safety, possessions, prestige and acceptance towards their partners and rival groups. The confession is the tool enabling the ethical agreement between legal agents and the adolescents, because it reconciles interests of both sides. Ethics dimension shows another paradox in the performance of both legal agents and state. While in the hearings of CIACA, the performance is conducted by the ethics seeking the life change of adolescents, in the hearings of PIA, it prevails ethics aiming at saving minimum conditions to the adolescents, although poor in physical, food, and emotional security. Such performances can be attributed to two distinct perceptions over the image of the ?victim? being linked to the adolescents authors of the juvenile proceedings in the broader social context: one perceives the adolescents as society?s and people?s victimizers who had their rights violated, and the other perceives the adolescents as victims of the social structures, of state actions and community actions in which they are involved in their social cultural contexts. / Esta tese analisa as pr?ticas dos agentes jur?dicos, dos adolescentes acusados da pr?tica de atos infracionais e seus familiares durante as audi?ncias no CIACA e na 3? Vara da Inf?ncia e da Juventude, na justi?a juvenil de Porto Alegre, e busca compreender as din?micas de produ??o da verdade neste sistema de justi?a juvenil. O foco de an?lise repousa no exerc?cio de poder e da resist?ncia pelos atores sociais presentes nas audi?ncias, buscando compreender como a dimens?o ?tica e a fluidez da categoria ?v?tima? permitem aceder a caracter?sticas do funcionamento da justi?a juvenil. Atrav?s do registro no di?rio de campo e da observa??o sistem?tica das audi?ncias da justi?a juvenil de Porto Alegre, foi poss?vel descrever os processos de produ??o da verdade a partir das intera??es entre os atores presentes nas audi?ncias, do exerc?cio do poder pelos agentes jur?dicos e da resist?ncia pelos adolescentes acusados e seus familiares. O estudo mostra que a act?ncia destes atores ? orientada por ?ticas opostas que se confrontam e se conciliam e por uma percep??o ambivalente dos agentes jur?dicos e de Estado acerca da figura ?v?tima? quando associada ao adolescente acusado. A ?tica que orienta as atua??es dos agentes jur?dicos no exerc?cio do poder visa introjetar nos adolescentes o modelo de vida tido como saud?vel, bom e correto por estes profissionais. A ?tica que orienta as act?ncias de resist?ncia dos adolescentes e seus familiares ao poder exercido pelos agentes jur?dicos fundamenta-se na cren?a de que a viol?ncia f?sica e a pr?tica de atos il?citos s?o instrumentos de media??o social que podem lhes garantir seguran?a, bens materiais, prest?gio e reconhecimento perante seus pares e os grupos rivais. A confiss?o ? o instrumento que torna poss?vel o acordo ?tico entre os agentes jur?dicos e os adolescentes, pois ela concilia interesses de ambos os lados. A dimens?o ?tica revela outro paradoxo na act?ncia dos agentes jur?dicos e de Estado. Se nas audi?ncias do CIACA a act?ncia ? orientada pela ?tica que busca a transforma??o da vida dos adolescentes, nas audi?ncias de PIA prevalece uma ?tica que visa resguardar condi??es m?nimas aos adolescentes, embora prec?rias, de seguran?a f?sica, alimentar e afetiva. Tais atua??es podem ser atribu?das a duas diferentes percep??es sobre a figura da ?v?tima? vinculada aos adolescentes autores de atos infracionais no contexto social mais amplo: uma percebe os adolescentes como vitimizadores da sociedade e das pessoas que tiveram seus direitos violados, e outra que percebe os adolescentes como v?timas das estruturas sociais, das a??es estatais e das rela??es comunit?rias em que est?o envolvidos nos seus contextos socioculturais.

Grounded in a Case Study-type of qualitative approach, semi-structured interviews were carried out using the Focus Group technique to gather information related to the role and actions of these mediators at the Museum, as well as to their capacity-building process. The data collected from the semi-structured interviews were compared between the groups in order to some kind of consensus to be reached about the role of mediators at the MCT-PUCRS, so that it could be possible to understand how the training of these professionals happens. Based on the Discursive Textual Analysis methodology (MORAES; GALIAZZI, 2011), three categories were established. These categories were defined through the analysis of the questionnaires completed by the 20 mediators who participated in the research, as well as the analysis of the semi-structured interviews which were conducted with the focus groups, whose members were mediators, other employees and the managing team of the MCT-PUCRS. This whole process of construction and emergence of the categories resulted in a series of meaningful information and data about the reality of mediation at the MCT-PUCRS, and such facts enabled a deeper understanding of the process of capacity-building of mediators (an indispensable element of their training) and of how this is connected to the formation of a ?mediating subject?. Additionally, by analyzing the results it was also possible to clearly see mediators who are imbricated in a series of interpersonal relations. Thus, the conclusion was that the training of a mediator occurs not only through capacity-building processes based on specific contents related to the interactive experiments of the Museum, but also by means of the life experience of these human beings, who deal with and relate to other individuals. It can be seen that the training of mediators involves aspects of subjective constitution, for the process of constitution of the ?mediating being? does not happen only when these people become aware of their roles and responsibilities in the exhibition area of the Museum, but in the course of their human actions ? among which the educational ones, for example, are a highlight ? and also during their daily lives and exchanges of experiences with their co-workers and the general public. / O presente trabalho objetivou compreender o processo de forma??o/capacita??o dos mediadores no MCT-PUCRS, a partir de uma abordagem de natureza qualitativa do tipo Estudo de Caso. Foram aplicados question?rios para obten??o do perfil dos mediadores, realizadas entrevistas semiestruturadas, utilizando a t?cnica de Grupo Focal para obten??o de informa??es relacionadas ? atua??o e ao papel desses no Museu, bem como seu processo de capacita??o. Os dados coletados a partir das entrevistas semiestruturadas foram confrontados entre os grupos entrevistados com o intuito de atingir uma esp?cie de consenso sobre o papel do mediador no MCT- PUCRS, para que se pudesse entender como ocorre a forma??o desse profissional. A partir da metodologia de An?lise Textual Discursiva (MORAES; GALIAZZI, 2011), foram estipuladas tr?s categorias que emergiram por meio da an?lise dos question?rios aplicados aos 20 mediadores participantes da pesquisa, bem como das entrevistas semiestruturadas realizadas com os grupos focais cujos integrantes foram mediadores, outros funcion?rios e a equipe diretiva do MCT-PUCRS. Todo esse processo de constru??o e emerg?ncia das categorias resultou na obten??o de uma s?rie de informa??es e dados significativos sobre a realidade da media??o no MCT-PUCRS, o que possibilitou um entendimento mais profundo sobre o processo de capacita??o dos mediadores ? elemento integrante e indispens?vel de sua forma??o ? e como esse est? diretamente relacionado ? forma??o do ?sujeito mediador?. Al?m disso, analisando os resultados, descortinou-se, tamb?m, fortemente um mediador imbricado em uma s?rie de rela??es interpessoais. Assim, concluiu-se que o processo de forma??o de um mediador n?o se faz apenas em capacita??es de conte?do espec?ficos e relacionados com os experimentos interativos do Museu, mas tamb?m na viv?ncia desse sujeito humano, que atende e se relaciona com outros indiv?duos. Foi poss?vel averiguar que a forma??o dos mediadores envolve aspectos de constitui??o subjetiva, visto que o processo de constitui??o do ?ser mediador? n?o ocorre apenas quando ele conhece seu papel e suas atribui??es na ?rea expositiva do Museu, mas atrav?s de suas a??es humanas ? dentre as quais podemos destacar, por exemplo, as educativas ? al?m de suas viv?ncias e trocas de experi?ncias com seus colegas e com o p?blico em geral.

This study was conducted with the participation of 20 students participating in a science club, two teachers of these students in regular schools and six parents of the same group of students, seeking information about the effects of participation in a club. The data was collected through observations, interviews and expressions of students during activities proposed by the researcher. Data were analyzed with a qualitative approach, using the Text Analysis Discourse, and the research was case study type. Based on the theoretical framework and analysis of the data collected, the science club was observed as a space to estimulate recommended aspects to the people of the XXI century. Within the intrapersonal characteristics, the expression of curiosity, ability to deal with errors and frustration, motivation and autonomy was showed at the studens actions. In some activities, however, students showed to have lack of autonomy to develop new tasks. At the interpersonal domain, the exercise of respect and patience were showed at the students in their relations with other colleagues. As for cognitive attributes, the students presented abilities to establish relationships between different subjects, as well as the contextualization of these. The critical and creative thinking was also present in the actions of the participants. Being present at all activities proposed, systemic thinking was at the essence of the investigated science club. Based at the results found in this research, it is recommended to implement more science clubs in basic education. Since these spaces can provide situations that can improve important elements to the contemporary world and thus contribute to the positive development of the current society, the expansion of opportunities like these is essential. / Essa pesquisa teve como objetivo compreender como as din?micas de clubes de ci?ncias repercutem no desenvolvimento de atributos recomendados para forma??o contempor?nea dos sujeitos. Este estudo foi realizado com a participa??o de 20 estudantes de um clube de ci?ncias, dois professores desses estudantes no ensino regular e seis pais do mesmo grupo de alunos, procurando obter informa??es relativas aos efeitos da participa??o em um clube. A coleta dos dados ocorreu por meio de observa??es, entrevistas e express?es dos estudantes durante atividades propostas pela pesquisadora. Os dados foram analisados com uma abordagem qualitativa, utilizando-se a An?lise Textual Discursiva, e a pesquisa foi do tipo estudo de caso. Com base no referencial te?rico e na an?lise dos dados coletados, observou-se o clube de ci?ncias como um espa?o para estimular aspectos recomendados aos sujeitos do s?culo XXI. No ?mbito das caracter?sticas intrapessoais, observou-se a express?o da curiosidade, a capacidade em lidar com erros e frustra??o, a motiva??o e a autonomia dos integrantes do grupo. Em algumas atividades, todavia, os estudantes demonstraram aus?ncia de autonomia durante a elabora??o de novas tarefas. Na perspectiva interpessoal, o exerc?cio e est?mulo do respeito e da paci?ncia nos estudantes participantes em suas rela??es com os demais colegas foram evidenciados. Quanto aos atributos cognitivos, os estudantes apresentaram habilidades para o estabelecimento de rela??es entre diferentes assuntos, assim como a contextualiza??o desses. O pensamento cr?tico e criativo tamb?m esteve presente nas a??es dos participantes. Permeando todas as atividades propostas, o pensar sist?mico esteve presente na ess?ncia do clube de ci?ncias investigado. A partir dos resultados encontrados nessa pesquisa, recomenda-se a implementa??o de mais clubes de ci?ncias na educa??o b?sica. Uma vez que esses espa?os podem contemplar situa??es que propiciam elementos de uma forma??o que s?o importantes na contemporaneidade e, portanto, contribuem para o desenvolvimento positivo da sociedade atual, a amplia??o de oportunidades como essas ? fundamental.

To collect the soil samples in each area were delimited plots of 1000 m2 with three replications for each study area. The bags were made in February 2008 in areas with different stages of succession is: area of initial eight years in the process of regeneration, intermediate with 17 years without human intervention and late registration without human intervention and an area of pasture five years without human interference, making the grass (Panicum maximum) in State Park Dry forest. Sampling was at random, taking nine composite samples consist of 27 single samples were taken at a depth of 0 - 10 cm in each study area to assess the diversity of AMF, six composite samples formed from 18 single samples of each study area for extraction and quantification of glomalin and three composite samples from nine single samples of each area of external mycelium. Were recovered 19 AMF species, belonging to the genera: Acaulospora (7), Glomus (7), Scutellospora (3), Gigaspora (1) and Archaeospora (1). The number of spores ranged from 37 to 640/50 cm3 of soil. The biomass of external mycelium is not statistically different between the four areas studied, but there is a growing trend in the pasture area toward the area of late succession. For the protein related to soil glomalin, the area of pasture had a higher amount of easily extractable glomalin, while the total glomalin was statistically equal between the four areas. The area with the initial sequence showed the greatest number of species (12). Were found in all areas A. scrobiculata, G. macrocarpum and G. tortuosum. The genus Glomus showed a higher percentage of occurrence in all areas studied. The area of intermediate succession, and the late without anthropogenic interference had lower densities and number of spores compared to the other areas studied indicating systems are more stable than other areas. / Esta pesquisa foi realizada no Parque Estadual Mata Seca (PEMS) no Munic?pio de Manga (MG), e teve como objetivo avaliar a ocorr?ncia e a diversidade de fungos micorr?zicos arbusculares (FMA), bem como a prote?na do solo relacionada ? glomalina (PSRG) e a biomassa de mic?lio externo em ecossistemas de Mata Seca no Norte de Minas Gerais. Para coleta das amostras de solo, em cada ?rea foram delimitadas parcelas de 1000 m2 com tr?s repeti??es para cada ?rea estudada. As coletadas foram feitas no m?s de fevereiro de 2008, em ?reas com diferentes est?gios de sucess?o, sendo: ?rea inicial com oito anos em processo de regenera??o, intermedi?ria com 17 anos sem interven??o antr?pica e tardia sem registro de interven??o antr?pica e uma ?rea de pasto com cinco anos sem interfer?ncia humana, tomada por capim coloni?o (Panicum maximum) no PEMS. A amostragem foi inteiramente ao acaso, tomando-se nove amostras compostas formadas por 27 amostras simples que foram retiradas na profundidade de 0 10 cm em cada ?rea estudada para avalia??o da diversidade de FMA, seis amostras compostas formadas a partir de 18 amostras simples de cada ?rea estudada para extra??o e quantifica??o da glomalina e, tr?s amostras compostas a partir de nove amostras simples de cada ?rea para mic?lio externo. Foram recuperadas 19 esp?cies de FMA, pertencentes aos g?neros: Acaulospora (7), Glomus (7), Scutellospora (3), Gigaspora (1) e Archaeospora (1). O n?mero de esporos variou de 37 a 640/50 cm3 de solo. A biomassa de mic?lio externo embora n?o tenha apresentado diferen?a estat?stica entre as quatro ?reas estudadas, pode-se notar uma tend?ncia crescente da ?rea de pasto em dire??o ? ?rea de sucess?o tardia. Em rela??o ? PSRG, a ?rea de pasto apresentou maior quantidade de glomalina facilmente extra?vel, enquanto que a glomalina total foi estatisticamente igual entre as quatro ?reas. A ?rea com sucess?o inicial foi a que apresentou maior n?mero de esp?cies (12). Foram encontradas em todas as ?reas A. scrobiculata, G. macrocarpum e G. tortuosum. O g?nero Glomus apresentou maior percentual de ocorr?ncia em todas as ?reas estudadas. A ?rea de sucess?o intermedi?ria e a tardia sem interfer?ncia antr?pica, apresentaram menores densidades e quantidade de esporos de FMA, em compara??o ?s demais ?reas estudadas, indicando serem sistemas mais est?veis que as demais ?reas.

The aleyrodids, commonly known as whiteflies, are pests that affect cassava crops and might induce economic losses, due to high infestation levels. The objective of this work was to survey the whitefly species that occur feeding on cassava (Manihot esculenta Crantz) crops in Rio de Janeiro State, and to evaluate their population levels and the influence of the climate aspects on these levels as well. Sampling of leaves were realised fortnightly from April to December 2007 during visits to three commercial cassava farmlands located in the municipalities of Rio de Janeiro, Itagua? and Japeri. The samples were collected and analysed under optical microscopy, in laboratory, applying a presence-absence methodology. The species identification was realised according to morphological characters of the 4th instar nymphs. Among the 16 aleyrodid species described feeding on cassava in the Neotropical region, Aleurothrixus aepim (G?ldi, 1886) and Bemisia tuberculata Bondar, 1923 were identified occurring in the State. B. tuberculata is reported for the first time feeding on cassava crops in Rio de Janeiro State. Population peaks of A. aepim occurred from May to June and in December 2007 in all the farmlands analysed. B. tuberculata population levels got peaks in different periods, depending on the farmland analysed. Low temperatures registered in July 2007 suggest being the reason of the population density reduction of both species. / O Brasil ? o segundo maior produtor mundial de mandioca e o maior produtor do continente sul americano. Os aleirod?deos, insetos comumente conhecidos como moscas-brancas, s?o pragas que acometem esta cultura e podem causar preju?zos econ?micos, em decorr?ncia de altas infesta??es. O objetivo deste trabalho foi levantar as esp?cies de moscas-brancas que ocorrem na cultura da mandioca (Manihot esculenta Crantz) no Estado do Rio de Janeiro, bem como analisar sua flutua??o populacional e a influ?ncia de fatores clim?ticos sobre seus n?veis populacionais. Foram realizadas amostragens de folhas, quinzenalmente, no per?odo de abril a dezembro de 2007, em lavouras comerciais localizadas nos munic?pios do Rio de Janeiro, Itagua? e Japeri. As amostras foram coletadas e analisadas sob microscopia ?ptica em laborat?rio, aplicando-se uma metodologia baseada em presen?a/aus?ncia. A identifica??o das esp?cies foi feita por caracteres morfol?gicos das ninfas de 4.? instar. Das 16 esp?cies de aleirod?deos descritas na regi?o Neotropical em plantas de mandioca, foram identificadas ocorrendo no estado, Aleurothrixus aepim (G?ldi, 1886) e Bemisia tuberculata Bondar, 1923. ? registrada pela primeira vez a ocorr?ncia de B. tuberculata Bondar em mandiocais no estado do Rio de Janeiro. Picos populacionais de A. aepim ocorreram no per?odo de maio a junho e em dezembro de 2007 em todos os locais pesquisados. B. tuberculata teve picos em per?odos diferentes, conforme o local pesquisado. Temperaturas baixas ocorridas em julho de 2007 sugerem ser a causa da redu??o da densidade populacional de ambas as esp?cies.
