This work examines the connection Syndicate/teachers profession trying to unveil the important role taken over by the Syndical movement in the process of professionalization of the militant teachers. For that, it describes and analyses the historical course of three Syndicates representatives of the teachers category Associação dos Professores Licenciados da Bahia APLB; Sindicato dos Trabalhadores em Educação de Pernambuco SINTEPE; Sindicato dos Servidores Municipais de Petrolina SINDSEMP acting in the micro-region of the San Francisco Valley, especially, in the municipalities of Juazeiro Bahia , and of Petrolina Pernambuco. It concentrates its interests on the contribution of the Syndicates for the professional development of these teachers in this region analysing the aspects related to emerging conflicts into the Syndical organization, to the attitude of these entities before the educational reality to their reinvindicative struggles to the formative dimension of the group actions. This study tries to answer the following questions: How has this syndical movement of teachers of state school of S. Francisco Valley been characterized? How do their actions reflect in the formation and professionalization of the teachers? Do teachers recognize the syndicate as a constructive space for the teaching profession? The methodological trajectory was directed through a qualitative approach of an etnomethodological character, using instruments for the understanding of this reality, The treatment of the data was based on the interpretative analysis of the speeches present in documents and through answers of the interviwees, having as a reference in this analysis the theoretical studies about syndicalism and the teacher professionalization. For a conceptual construction of this work it was studied these two categories from their genesis, from the social historical evolution of their concepts and the up to date discussions that give explanations about the teachers syndical movement and about the process of teachers professionalization. As thesis of this study it was defended the idea of that the teachers syndicates have contributed expressively in the process of the construction of the teacher profession of the militant teachers of this in the micro-region of the S. Francisco Valley. Once the teachers participate actively in this movement promoted by the syndical entities, the teachers develop the critical sense of the educational realty; improve their formation and reinvindicate from the State this condition as a Right; fight for better conditions in the work; reinvindicate the salary valuation and, try to construct an image of teacher basing on a professional model. The contribution of the Syndicate in the process of teachers profissionalization, is more evident in its external dimension that chacterizes the profissionalism, on the related aspects: to the forms of participation in the definition and the management of the educational politics; to the political struggles for the achievements of the professional status, to the recognition and of his eventual valuation. The syndical actions have repercussions with less intensity in the inside dimension that defines the profissionality, in the related aspects: to the administratation of the pedagogical processes in schools and in the classroom; to the acquisition of branches of knowledges; to the epistemological criticism of the acquirements mobilized in the teaching; the curricular question to the mediation that make possible the learning at school and in the classroom

Theatrical phenomenon borned in the Italy the Comedy dell Art concerned to it climax in the XVI century and spreading itself by the word than can be sight like the theatre base modern. Lasting parallel the conventional theatre since the three hundred years, this gender influenced significativly the making theatrical in the Europe graces the popular character of its simulation turned for the improvise. In spite of treat a theatric manifestation no more existing in the present time, we understand that the Comedy dell Art was constituted in one artistic language whose esthetics centralized in the popular fanciful and in the improvise permitted a rich possibility of verbal and not-verbal communication that today can to be taken again in contemporary productions theatricals. Departing of an approach of esthetics, this work has with purpose concentrate the references esthetics that configure that one artistic manifestation such that one references can contribute for the Arts teaches in the present times. We appeal the text and image of Comedy dell Art, such this historical reference that in context, with fountain investigated that mean and if complementary in one esthetic reflection for the creation of meaning diverse and news interpretations for the purpose investigated if having with base some analysis categories such as: the actor s body, the actuations spaces and the esthetics categories such the ugly, the comic and the absurd. To investigate the Comedy dell Art esthetic in the ambit of the teach of Arts Scenics is a manner of be understand the artistic universe of three century behind that can be meant, revived, in the marking possibilities of an art teach able to incentive the critical, the appreciation, the discussion and the transgression of instituted true. Having investigated the exhibition Comedy dell Art esthetic we rebound four stich that we judge significative for we think the Arts Scenics teach, they are: the articulation between actor s body, the text and the space actuation in the play; statement what it is given between actor s body and the on-looker and the every gesture that did share of scene in a popular scenic space; a conception actor s body that transgress with the true duty socially that is capable the to admit its dimension Dionysian, creative and ambiguous in the to do theatrical; the text conception that get beyond the ambit the word writing by the dramatist and talked by actors, if spreading the other elements significance in the scene like gesture, the parody, the recent news, the gags and the word used in the day-to-day; the scenic space like a statement symbolic between actors and on-looker that make a quality of amusement pact supported by the scenic true of artist that actuate in not usual spaces bid at an auctioning degrees of participation in the building the scenic phenomenon; and the importance of esthetics categories such as the ugly, the comic and the absurd, those categories that foundation like a do scenic transgressor make a possible exchange mutual between actor and appreciator. The statement of esthetics categories in joint continuous between the body, the text and the scenic space evident themselves in doing theatrical and in the its appreciation. We believe that the reflection esthetic about the Comedy dell Art in the arts class, consider the stich detached, can favor possibilities of to share discovery, ideas, feelings and attitudes, and can permit the observation of different stich of view, establishing the statement of individual with the group in a participative and democratic form

O objetivo deste estudo foi avaliar os efeitos da utilização de diferentes ingredientes fibrosos nas dietas sobre o desempenho, a composição corporal e a morfometria intestinal de juvenis de pacu. Foram avaliadas cinco dietas isoproteicas (23% de proteína digestível), isoenergéticas (3250kcal de energia digestível/kg) e isofibrosas (9% de fibra bruta), sendo a principal fonte fibrosa de cada constituída por farelo de soja, casca de soja, farelo de girassol e polpa cítrica; esta última em dois níveis de inclusão (30 e 45%). Foram utilizados 300 juvenis de pacu (25,12±0,78 gramas), alojados em 25 aquários (200 litros). Os melhores resultados de crescimento e conversão alimentar foram obtidos com as dietas contendo farelo de soja e farelo de girassol. As dietas contendo casca de soja e polpa cítrica prejudicaram o desempenho dos juvenis de pacu, e o efeito negativo foi acentuado com o aumento da inclusão de polpa cítrica. Além disto, somente nos peixes alimentados com a dieta com 45% de polpa cítrica foi observada diminuição na densidade de vilosidades por área no epitélio intestinal. A partir dos resultados obtidos, pode-se concluir que alguns ingredientes fibrosos podem afetar negativamente o desempenho e as características do epitélio intestinal de juvenis de pacu.

This dissertation is the result of concerns with the theoretical-methodological and pedagogical learning processes occurred in the practice of physical education in school, which accompany me since the initial training, when I experienced learning in a piecemeal fashion, focused on technicality and sportivization. In order to better qualify the pedagogical interventions of physical education in school, I have always been worried on applying what I received at the University, but the routine of classes was always demanding others doings. In this sense, there were many moments of epistemological ruptures occurred in my training, in which I always sought new investment in training to account for the provision of a more humanistic and grounded in real educational precepts physical education. To that end I had to reflect on the pedagogical interventions throughout my training, in order not to carry out the activities as heavy doings, but as metamorphoses of knowledge and thus generating learning for students. Thus, this dissertation fits into this context with the overall goal of discussing my professional career, considering the epistemological ruptures of Physical Education, occurred in my training and expertise. The objective is also to identify the contributions of these formations in professional activities, centered on storytelling and reflection of significant experiences in the teaching of sports and Physical Education. We highlight the paradigm shifts, leaving the gymnastic methods, through dance-physical education method, psychomotor, reaching the contemporary critical theories experienced from the culture of movement as well as its implications for professional practice. We chose a qualitative research, using the autobiographical method, using as sources or techniques, narratives, photographic recording and video samples. In the studies within the area of education, for the most part, qualitative research came to oppose the positivist view of the quantification on analysis of social phenomena. New ideas were appearing in order to present innovative perspectives to understand the real. The survey data will be presented in narrated form (descriptive), analyzed based on the theoretical framework that guides the study, especially authors who discuss school physical education, vocational training and body conception. We believe our study may be of relevance for training in Physical Education that as from pedagogical reflections in certain historical realities, envisions being able to open new perspectives for the performance of other physical education teachers

O nitrogênio é um nutriente essencial ao feijoeiro. Contudo, ainda há dúvidas sobre qual fonte e dose utilizar para o fornecimento desse nutriente em cobertura à cultura, no sistema plantio direto. O objetivo deste trabalho foi avaliar a influência de fontes e doses de N, aplicadas em cobertura, na nutrição e produtividade do feijoeiro (Phaseolus vulgaris L.) cultivado no sistema plantio direto, em um Nitossolo Vermelho. O delineamento experimental foi o de blocos ao acaso com quatro repetições, num esquema fatorial 2x4, constituído por duas fontes de N (nitrocálcio e uréia) e quatro doses de N (0, 30, 60 e 120 kg ha-1) em cobertura. A aplicação de doses elevadas de N, na forma de nitrocálcio, promoveu maior absorção de nitrato, K, Ca e Mg pelo feijoeiro em plantio direto, em comparação com a aplicação de uréia. A adubação nitrogenada em cobertura, utilizando como fonte o nitrocálcio ou a uréia, proporcionou aumento no teor de N nas folhas, na massa de matéria seca da parte aérea, no número de vagens por planta e na produtividade do feijoeiro no sistema plantio direto, em sucessão a aveia-preta, até a dose estimada de 95 kg ha-1 de uréia.

Com o objetivo de avaliar o rendimento da batata-doce [Ipomoea batatas (L.) Lam.], cultivar Rainha Branca, submetida a fontes e parcelamentos da aplicação de 80 kg ha-1 de nitrogênio, instalou-se um experimento, no período de abril a agosto de 2007, na Universidade Federal da Paraíba, em Areia. O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 2 x 7, com duas fontes de nitrogênio (uréia e sulfato de amônio) e oito de épocas parcelamentos da aplicação (100% no plantio; 100% aos 30 dias após o plantio (DAP); 100% aos 60 DAP; 50% no plantio e 50% aos 30 DAP; 50% no plantio e 50% aos 60 DAP; 50% aos 30 e 50% aos 60 DAP; 33% no plantio, 33% aos 30 e 33% aos 60 DAP), com quatro repetições. Foram avaliados o peso médio de raízes comerciais, a produção e o número de raízes comerciais por planta e as produtividades total e comercial de raízes de batatadoce. O maior peso médio de raízes comerciais (294 g) foi obtido com o parcelamento do N, como uréia, 50% no plantio e 50% aos 30 DAP. O parcelamento de N 33% no plantio, 33% aos 30 DAP e 33% aos 60 DAP na forma sulfato de amônio foi responsável pela maior produção de raízes comerciais por planta (337 g). Para o número de raízes comercias e as produtividades total e comercial, o N na forma de sulfato de amônio parcelado 33% no plantio, 33% aos 30 DAP e 33% aos 60 DAP proporcionou os maiores valores, 1,50 raízes, 30,5 e 28,4 t ha-1, respectivamente.

Objetivou-se avaliar os efeitos de diferentes formas químicas de compostos nitrogenados (proteicos e não-proteicos) e de carboidratos (amiláceos e fibra solúvel) sobre o consumo, a digestibilidade e a síntese ruminal de proteína microbiana em bovinos sob suplementação durante o período das águas. Foram utilizados cinco novilhos mestiços Holandês × Zebu, com peso vivo (PV) médio inicial de 211 ± 35 kg, fistulados no rúmen e abomaso. Os tratamentos foram: controle (somente pasto); e suplementos formulados à base de milho + farelo de soja; milho + ureia; polpa cítrica + farelo de soja; e polpa cítrica + ureia. Os suplementos foram balanceados para apresentar 30% de proteína bruta (PB), com base na matéria seca (MS), e fornecidos na quantidade de 3 g/kg PV. O experimento foi conduzido segundo delineamento em quadrado latino 5 × 5, em esquema fatorial 2 × 2 + 1, composto de duas fontes de compostos nitrogenados, duas fontes de carboidratos e tratamento controle. O consumo de pasto reduziu com o fornecimento de suplementos, com coeficiente médio de substituição de 2,11 g de MS de pasto/g de MS de suplemento. A suplementação não alterou os coeficientes de digestibilidade total e ruminação da MS nem o teor dietético de nutrientes digestíveis totais (NDT). Os animais sob suplementação apresentaram maiores coeficientes de digestibilidade total e ruminal da proteína bruta. A eficiência de síntese de proteína microbiana (EFSM), média de 123,1 g PB microbiana/kg de NDT, não foi alterada pela suplementação. Contudo, os animais sob suplementação com milho apresentaram maior EFSM em comparação aos animais sob suplementação com polpa cítrica (137,6 e 106,1 g PB microbiana/kg de NDT, respectivamente). A suplementação proteico-energética para bovinos mantidos em pastos tropicais durante o período das águas não causa benefícios nutricionais, o que reflete o alto coeficiente de substituição da forragem pelo suplemento.

Quarenta bovinos machos, com 30 meses de idade e 371 kg, foram distribuídos em um delineamento em blocos casualizado com esquema fatorial 3 x 3, para avaliar o desempenho e rendimento de carcaça quando alimentados com diferentes fontes protéicas (Amiferm, uréia e farelo de soja) e volumosos (pastagem de capim-braquiária, cana-de-açúcar e silagem de milho). As dietas foram balanceadas para conterem níveis semelhantes de em e PB. A interação volumoso x fonte de N não foi significativa para nenhum dos parâmetros estudados. O ganho de peso vivo diário (GPV/dia) dos animais alimentados com cana-de-açúcar (0,83 kg) não diferiu dos mantidos em pastagem (0,82 kg), mas ambos foram menores que dos animais alimentados com silagem de milho (1,09 kg). As diferentes fontes de N proporcionaram GPV/dia semelhantes, com valores de 0,94; 0,83 e 0,97 kg, para os animais que receberam uréia, Amiferm e farelo de soja, respectivamente. As dietas contendo farelo de soja proporcionaram maior ganho de carcaça diário (0,57 kg) em relação ao uso de Amiferm, não diferindo da uréia (0,55 kg). Não houve diferença entre volumosos e fontes nitrogenadas para rendimento de carcaça, rendimento de carcaça do corpo vazio, rendimento de carcaça do ganho de peso e espessura de gordura, com média de 51,03%, 54,49%, 60,10% e 8,5 mm, respectivamente. O uso de Amiferm proporcionou ganhos de peso e rendimento de carcaça semelhantes às demais fontes protéicas.
