Célestin Freinet was one of the most memorable educators of the twentieth century. He presented some educational alternatives that had the objective of stimulating the construction of pedagogic actions to promote the social development of the student based upon a work centered on the free expression as the way to self-structure the knowledge. With a permanent proposal of research based on the enquiry-based learning, Freinet set human capacity (cognitive, social-affective, psychometrical) taking cooperation in consideration on the processes of knowledge construction. Based on this referential, this present work has the objective to show Freinet s pedagogy in a continuous teaching action from 2nd to 5th grade focusing the teacher s discourse and also the educative practice of the students of a city public school in Natal. The observed work revealed the teacher s discourse and educative experience and delineated the students development while immersed into Freinet s educational practice. By virtue of the nature and specificity of the theme that guided our research, we chose a qualitative approach to it, as a way of conducting ourselves during our investigative process. We observed and analyzed the method that was used to conduct the activities in the classroom, as well as the ways of expression that the children used through drawings, words (oral text), or through writing. We highlight, among the written texts, the individual and collective texts, and also letters and notes, which during some moments served as a base to express a diversity of languages. The results, after a analyzing the research data, point towards a teaching practice that favors the construction of a significant learning process through the grasping of the school environment, on which all these factors are based: society, knowledge acquisition, abilities, attitudes and values. This learning process also strengthens human solidarity bonds and mutual tolerance, on which the student s social life is seated.

La musique, plus qu`um mot et le texte écrit, a le pouvoir de produire le déplacement du sujet en relation aux contingences du temps e de l´espace. Entendre de la musique est plus que de l´amusement. Comme un artifice cognitif qui ultrapasse l´expérience analytique e métonymique, les formes tonales doublent la réalité, expandent les sens, actionent l´imagination, retotalisent les sentiments, amplient les expériences, permettent la rencontre du sujet avec les éssences des phénomènes qui ne sont pas traductibles par les mots. Nous écoutons de la musique pour restituer notre dignité e conférer à la vie plus de vérité, plus de concrétion (Santiago Kovadloff). La mélodie permet l´expérimentation des états de cohésion, de conéction pleine entre sens et intention, entre commencement et fin, de la finitude de la vie (Schopenhauer). Le phénomène musical provoque l´expréssion de la douleur, de la souffrance et, au même temps, du jubile et de la joie, réliant nature et homme (Nietzsche). Tenant comme base cette compréhension, la dissertation tient dans la musique une importante métaphore pour comprendre la complexité humaine, une fois qu´elle propicie une écoute sensible du monde et mobilise dans le sujet l´expérimentation de divers états de l´être. Nous pouvons dire que la musique est un opérateur de la conaissence parce qu´elle fait affleurer l´écoute intérieure, la rencontre du sujet avec lui même. Cet opérateur cognitif actione les pôles de l´ésprit qui font dialoguer sensibilité, éthique et esthétique, ordre et chaos, silence et bruit, mouvement et pause, repétition et inovation. Par l´expérience musicale, nous habitons des formes hibrides de sensibilité et raison. L´inachèvement, notre principal caractéristique comme humains, a, dans la musique, une image impair, parce que la musique est l´expression du dévir. Pour tisser ces arguments, la dissertation part des études de Schopenhauer et Nietzsche sur la musique, esthétique et métaphysique; Expose des fragments de la biographie de trois grands penseurs contemporains (Werner Heinsenberg, Ilya Prigogine et Edgar Morin) accentuant la présence de la musique en ses vies; et, par fin, présente ce que nous appelons biographies sonores de quatre artistes-musiciens brésiliens (Benedito Juarez et Gil Jardim, de São Paulo, et Ronaldo Ferreira de Lima et, Cleudo Freire, du Rio Grande do Norte)

Cette étude a été faite à partir d une expérience d alphabétisation chez des jeunes et des adultes dans deux groupes du "Projet Réduction de l analphabétisme" realisé par l Université Fédérale du Rio Grande do Norte, le bureau du Ministere de l Éducation et la Préfecture Municipale de Natal-RN. Nous avons choisi la méthode qualitative de recherche, en utilisant l observation de la dynamique en salle de classe, considérant les acteurs sociaux comme étant le sujet actif du processus historique, culturel et politique. Nous avons voulu colaborer dans ce theme en proposant un référenciel théorique et pratique, en visant le dynamisme de la salle de classe, à travers la vision de I alphabétisation centrée sur les utilisations sociales de la lecture et de l écrit; la conception dialogique de Paulo Freire, basée sur la propre culture de l élève et sur sa valorisation en tant que sujet actif de l apprentissage ; la proposition pédagogique de Célestin Freinet dans son aspect de la dynamisation de la salle de classe renforçant le principe de la libre expression, de la colaboration, de l activité et le respect du rytme individuel, pour le succes scolaire. Nous avons rappelé que Célestin Freinet e Paulo Freire ont contribué dans la conscientisation individuelle, sociale, culturelle, politique, de l éleve par le processus scolaire. Nous avons séparé l intérêt et la participation de celles qui alphabétisent et des élêves dans ce processus éducatif. Nous avons constaté tout au long du travail des changements dans la posture de celles qui alphabétisent, surpassant les pratiques centrées dans le formalisme, et le verbalisme fruits de l Éducation traditionnelle. A vançant dans le sens de l Abordage Constructiviste de la connaissance, garantissant un climat de sécurité, de dynamisme et de respect en salle de classe

Dois experimentos foram conduzidos em pomares de goiabeira 'Paluma', nos municípios de Monte Alto e Vista Alegre do Alto-SP. No primeiro experimento, avaliou-se o efeito de formulações de fungicidas cúpricos, aplicados isoladamente e em mistura com mancozeb, quanto ao efeito fitotóxico em botões florais e em frutos de goiabeira, em três estádios de desenvolvimento. No segundo experimento, foram avaliados os mesmos fungicidas usados no primeiro experimento, sendo, porém, acrescido do tratamento constituído por tebuconazole, cujo alvo foi sua eficiência no controle da ferrugem. No primeiro experimento, verificou-se que nenhum dos fungicidas testados causou abortamento de flores ou outros tipos de sintomas de fitotoxicidade em frutos de tamanho inferior a 15 mm de diâmetro. Contrariamente, estes fungicidas, quando aplicados isoladamente, em frutos entre 25 a 35 mm de diâmetro, causaram sintomas severos de fitotoxicidade. em frutos de tamanho superior a 40 mm de diâmetro, estes fungicidas causaram sintomas de fitotoxicidade de níveis leves a moderados. A combinação de fungicidas cúpricos com mancozeb causou sintomas de fitotoxicidade em níveis leves, enquanto com mancozeb isoladamente não foram verificados sintomas de fitotoxicidade. No segundo experimento, verificou-se que os fungicidas cúpricos, aplicados isoladamente, foram eficientes no controle da ferrugem da goiabeira, apresentando eficiência comparável ao tratamento-padrão representado por tebuconazole. Esta eficiência foi também observada mediante o emprego da combinação mancozeb e óxido cuproso ou hidróxido de cobre.

O objetivo deste trabalho foi determinar o padrão de revoadas e a influência de fatores meteorológicos e de Brassicaceae sobre populações de formas aladas dos pulgões Brevicoryne brassicae, Lipaphis erysimi e Myzus persicae. Os pulgões foram amostrados em armadilhas tipo bandeja amarela com água, entre julho de 1997 e agosto de 2005. A correlação parcial de Pearson foi utilizada para verificar a influência da temperatura do ar, umidade relativa, chuva e insolação na abundância de alados das três espécies. A influência de brassicáceas foi avaliada pelo cálculo do número de graus-dia acumulados acima da temperatura base inferior dessas plantas. Lipaphis erysimi foi mais numerosa que M. persicae e B. brassicae. Os alados de B. brassicae apresentaram revoadas que predominaram de agosto a outubro, com o pico de abundância em setembro. Os períodos de revoada de L. erysimi e M. persicae foram mais longos que o de B. brassicae, com os maiores picos de L. erysimi e M. persicae observados de abril a novembro e de junho a outubro, respectivamente. A população de B. brassicae teve correlação significativa com as temperaturas máxima e mínima, insolação e umidade relativa do ar, enquanto L. erysimi e M. persicae foram afetadas apenas pela insolação e umidade relativa.

O presente trabalho teve por objetivo avaliar a influência de diferentes concentrações de ethephon na expressão precoce de sintomas de Guignardia citricarpa em frutos de laranjeira 'Pêra-Rio'. Para tal, frutos assintomáticos e isentos de aplicações com fungicidas, com 20 e 28 semanas após a queda de pétalas, foram coletados em área de comprovada existência da doença, no município de Conchal-SP e levados ao Laboratório de Fitopatologia da FCAV/UNESP, em Jaboticabal-SP, onde foram tratados com soluções nas seguintes doses de ethephon: i) 1,57 g L-1; ii) 2,10 g L-1; iii) 2,42 g L-1; iv) Testemunha (água). Todas acrescidas de imazalil a 0,25 g L-1, para prevenir podridões de pós-colheita. Após os tratamentos, os frutos foram mantidos em câmara incubadora para B.O.D., calibrada à temperatura de 25ºC ±1ºC, por 15 dias. Posteriormente, os frutos foram submetidos a quatro avaliações, em intervalos semanais, sendo atribuídas notas que variaram de zero (ausência de sintomas) a 6 (sintomas severos). Os dados da severidade da doença observados nos frutos colhidos prematuramente e submetidos aos diferentes tratamentos com ethephon foram comparados aos observados em frutos ensacados e não ensacados, mantidos no campo até a maturação natural. Constatou-se maior equivalência de sintomas nos frutos com idade entre 20 e 28 semanas, quando estes foram tratados com 2,10 g L-1 de ethephon e avaliados entre 28 e 35 dias. Concluiu-se que o emprego de ethephon, nestas condições, viabilizou a expressão precoce dos sintomas da mancha preta em frutos contendo infecções quiescentes de G. citricarpa, com antecedência de, pelo menos, 105 dias antes da colheita. Tal resultado constitui-se, portanto, em alternativa de grande aplicabilidade na detecção precoce de sintomas de mancha preta.

This production is a reflection about the practices/experiences involving the teaching of the dance developed by the teachers in the Núcleo de Educação Infantil (NEI/UFRN), with the children from 2 to 7 years old, having as objectives: describe and interpret the lived experiences with the dance focusing on the meaning of the dance and organization of the pedagogic job, identify blanks in the pedagogic practices of dance and appoint possible perspectives to the teaching of dance on the infant education. The way from the investigation has begun with the following question: Who do the teachers understand the dance and live it on the Núcleo de Educação Infantil? The research of phenomenological orientation toke as methodological reference the qualitative approach from the placed phenomenon type, this one has as beginning the interest on the phenomenon by the way as it happens on the lived experience from where comes the knowledge with we can present about the world, trying to interpret it, understand it on its essence/existence. The interviews showed that the researched subjects give to the dance different meanings and consequently present variations on the manner to organize the work around this knowledge. The most of the teachers recognizes the dance as a culture expression, being a priority on the school the job with the folkloric dances. They recognize too the dance as knowledge/content coming from the Arts and Physical Education areas and its relation with the knowledge from others areas on the pedagogic action. There were found different process on the way to conduct the job with the dance in relates from experiences done with dance at NEI and, therefore, of teach/learn this knowledge. Its perceptible that exists a systematic work with the objective of develop the dance and its various educative possibilities, starting from the research about its origins, the exploration of the movement, the contextualization until the artistic practice. Those possibilities are reinforced on the school s curricular propose. Some experiences have as a priority the free expression, the dance s vision without context or the reproduction of movements as stand manners of teaching dance, situations like those observed on the investigation as products from the blanks on the academic formation from the teachers with must be fixed. The interpretation of the experiences with dance, described by the teachers from NEI, connected with the theoretical referential from the investigation, allowed to appoint three perspectives to the work with dance in the infant education, having as main interlocutors Merleau-Ponty and Rudolf Laban: the dance as the body s language; the dance and its movement factors; imitate, improvise and play: manners of draw ways to dance. On those process are emphasized the dance on the scholar context, the elements that constitute this language and the forms of appropriate from it supported in a ludicrous, poetic and educative vision, having as focus the children s education on its peculiarities and possibilities

The present study aims to investigate the conceptions of teachers and management team of the Colégio Nossa Senhora das Neves - Natal / RN about curriculum, school architecture and possible relationships established between these components. To develop the study, we rely on the theoretical contributions of Viñao Frago (2001), Escolano (2001); Benconstta (2005), among others, about the architecture school, and with regard to curriculum, ancoramo us in theoretical reflections Silva (2000, 2006, 2008). We assume that the school place is a social construct and as such, reflects the interests of certain groups, to organize, establish ways to condition their unctions and uses. In this space, people's lives is planned, both those who work there, as those who study there. Thus, the architecture school promotes, through representations, signs, symbols and shapes, certain charges that impact the ways of being and acting subjects by establishing appropriation and expropriation of rights and legitimate forms of inclusion and exclusion. Thus, it is an expression of power. A power that is expressed in the form of lead the way people should behave in a certain space. Clarity on these aspects of the architecture school is important, since in the same way that the opinion of several experts is important to discuss the adequacy of school architecture (environmentalists, architects, engineers, planners), the / the teacher / and the / as managers / must also meet the educational nature of the architecture school, so as to present its share of contribution in order to make the post-school conducive to learning multiple. From this perspective, we analyze the concepts of four teachers and eight individuals who are part of the management team of the CNSN, whose views were seized through participant observation, semi-structured interviews and documentary analysis. The construction of the data indicated levels of conceptual curriculum varied, ranging from those rooted in traditional theories of curriculum as those regarding the curriculum tied to discursive and contextual aspects. The conceptions of architecture school, predominantly focused on the aspects of the architecture school materials and most established subject, differently, relations between curriculum and school architecture

Este trabalho foi desenvolvido com o objetivo de pesquisar o efeito da energia da dieta sobre a temperatura do cólon e concentração de proteína de choque térmico (Hsp70) de frangos à temperatura ambiente, bem como durante o estresse calórico agudo. Os frangos foram criados até 51 dias de idade e alimentados com dietas contendo nível de energia alto (13.186 kJ EM/kg) ou baixo (12.139 kJ EM/kg). No 21º e 51º dias de idade, a temperatura do cólon foi medida e amostras de fígado foram obtidas para quantificação da Hsp70 através da análise por Western Blotting.. Nessas mesmas idades, a resposta das aves ao estresse calórico agudo (37º C/5 h) foi avaliada (temperatura colón e Hsp70 no fígado). Os resultados mostraram que aos 21 dias de idade, à temperatura ambiente, a temperatura do cólon e a concentração de Hsp70 hepática não foram afetadas pela energia da dieta, mas, aos 51 dias de idade, os frangos alimentados com baixos teores de energia apresentaram menores concentrações de Hsp70 no fígado. As respostas ao estresse calórico agudo mostraram que as aves alimentadas com dietas de alta energia tiveram menor incremento na temperatura do cólon, bem como no conteúdo de Hsp70 hepático. Os resultados desse estudo sugerem que a síntese de Hsp70 no fígado pode ser afetada pela energia da dieta e que frangos alimentados com altos níveis de energia podem ter a termotolerância alterada em condições de estresse agudo pelo calor.

The objective of this study was to evaluate the influence of methods of preparation in postharvest conservation of minimally processed products of cactus pear fruits. Ripe cactus pear fruits orange-fleshed, from a commercial orchard in the region of Valinhos, SP, Brazil, were used. After selection, the fruits were washed and the surface sanitized with a solution of dichloro s. triazinatriona sodium dihydrate (Sumaveg (R)) 200 mg 100g(-1) of free chlorine for 5 minutes. Fruits were then stored at 12 degrees C for 12 hours before processing. The first process was the removal of the shell and ends. Then, the fruits were cut longitudinally into two halves, peeled and sliced in 2 cm thick cross-sections. The whole fruit, halves and slices were packaged in polyethylene terephthalate containers (Neoforma (R) N-94). These units were stored at 3 degrees C for 16 days and analyses were performed every 4 days. The weight loss, the content of soluble solids (SS), the titratable acidity (TA), the ratio (SS / TA) and the ascorbic acid content were evaluated and the sensory analysis of products was performed. Whole fruits were preferred concerning the purchase intent and showed better results regarding the content of soluble solids, titratable acidity, soluble solids / titratable acidity and ascorbic acid content. The highest weight loss was observed in slices.

The objective of this work was to evaluate the effect of the physical form and quantity of pre-starter diet on the broiler chicks performance. In the first trial, 684 day old males were distributed in a randomized design of three treatments with six replicates of 38 birds. The physical forms of pre-starter diets tested were: mash diet; crumb diet and pellet diet. Another was conducted with 912 day old male distributed in a randomized design of three treatments with eight replicates of 38 birds. The treatments consisted in feeding the broiler chickens with 150 g/bird; 200 g/bird and 250 g/bird. After that, all the birds were fed with the same feed program. In the first week and at 21 days old the birds fed with mash pre-starter diet had body weight gain lower than those fed crumbed and pelleted diets. The variables studied were not affected by the quantity of diets. In conclusion, the physical form of pre-starter diet was important for initial performance and the quantity of pre-starter tip to 150 g/bird did not improve the development of broiler chicks.

Foram realizados três experimentos com o objetivo de avaliar o efeito da suplementação de minerais na forma orgânica na dieta de codornas japonesas na fase de postura sobre o desempenho e a qualidade de ovos das aves. Os níveis de minerais utilizados por kg de ração, para cada experimento, foram: controle, 0,35, 0,70 e 1,05mg de Se orgânico (experimento 1); controle, 50, 100 e 150mg de Zn orgânico (experimento 2) e controle, 60, 120 e 180mg de Mn orgânico (experimento 3). As aves foram distribuídas em delineamento inteiramente ao acaso, sendo oito aves por parcela e seis repetições por tratamento. Foram avaliadas as características de desempenho - consumo diário de ração, peso dos ovos, porcentagem de postura, conversão alimentar por massa de ovos e por dúzia de ovos e viabilidade - e qualidade dos ovos - unidade Haugh, índice gema, porcentagens de casca, albúmen e gema, espessura de casca e gravidade específica. O Zn orgânico suplementado à dieta melhorou o desempenho das aves e a qualidade dos ovos, o Mn orgânico melhorou a qualidade da casca e reduziu o peso dos ovos e o Se não apresentou efeitos sobre as características avaliadas.
