El desafío de la parcería en la implantación del PRONERA: el caso del Proyecto Alfabetización Ciudadana en Noreste de Pará se constituye en un estudio sobre las políticas públicas de educación del campo. El trabajo tiene como objeto de análisis la implantación del PRONERA, a partir del estudio de caso del Proyecto de Alfabetización Ciudadana en Noreste de Pará, con el objetivo de comprender como la parcería, principio operacional y metodológico propuesto por el PRONERA, se concretó en la implantación del Proyecto y cuales sus posibles implicaciones en las políticas públicas de educación del campo. Entre los procedimientos metodológicos, realizamos la investigación bibliográfica y documental que nos permitieron situar la educación del campo en términos históricos y políticos, sistematizar la constitución y la organización del PRONERA y reflexionar acerca de la parcería a partir de diferentes ópticas. Realizamos también la investigación de campo por medio de entrevistas semi-estructuradas, con el propósito de analizar la implantación del Proyecto da Alfabetización Ciudadana, a partir del dialogo con los actores sociales involucrados. Los resultados de las análisis indicaron que, históricamente, las políticas públicas de educación destinadas a las poblaciones de la zona rural fueron instituidas verticalmente, desvinculadas de la realidad del campo e incompatibles con las necesidades e intereses de los sujetos. Constatamos que, en período reciente, movimientos sociales del campo reivindican y proponen acciones que se establezcan como políticas públicas de educación del campo. Identificamos que el PRONERA resulta de ese movimiento y se presenta como anuncio de una política pública de educación del campo, teniendo como diferencial el hecho de ser un programa del gobierno federal idealizado fuera de la esfera gubernamental, construido por los movimientos sociales del campo y presentar, entre otras innovaciones, el modelo de parcería y la gestión compartida, participativa y democrática. En esta perspectiva, en este estudio de caso, se evidenció que la parcería, frente a los conflictos y las disputas entre sus miembros participantes, no es el problema de la implantación del PRONERA, sino su punto fuerte. De este modo, la parcería es uno de los elementos necesarios para la construcción de políticas públicas, en particular, de educación del campo, una vez que posibilita la interacción de instituciones públicas y movimientos sociales locales, atribuyendo legitimidad a la educación del campo. Al promover un proceso de aprendizaje democrático, la parcería se presenta como estrategia de democratización de la educación del campo.

This thesis aims to investigate the Agronomy course in the perspective of the graduation course for the settlers of the Universidade Federal do Pará- Marabá. This course requires a partnership with the social movements of the North region of the country, with the purpose to understand knowledge production and how learning process occurs from the point of interaction and reliable relationships which are established in the organization during the course. The base of theses studies is to reflect of how the dialogue and learning processes occurred during the Agronomy course and resulted in changing in the teachers behavior and in the other integrated members of the group and mainly in the graduating settlers students. These changings happens as a consenquence of the dialogue production between the most varied areas, different people and institutions which take collective decisions. I observe educational actions, researches, extention concepts of extension and also development researches presented in the educative actions discussed by Freire (1985), Simões (2001, 2003) e de Amartya Sen (2000). The theory in which I am basing these studies are based in Boaventura de Souza Santos Simões (2001, 2003) and Amartya Sen (2000). Methodologically I analyse knowledge production by sudying the thesis and scientific works related to rural education, social movements, university and higher education in the last 20 years. I analyze the scientific works of all settler students, and besides, I do open interviews with the students, as well as, with the teachers and the leaders of social movements (MST, FETAGRI, CPT, EFA/FATA). I organize and analyze all the speeches from the ecological knowledge as defined by Boaventura de Souza Santos (2006). Finally, I visit five towns of municipal districts of the southeast of Pará, which represents the final methodological part of the research, in order to verify in loco the practices of the experiments purposed as final activity of the Agronomy course. I organize the work in five areas composed by the occupational process and the initiatives which emerged from them; development model and the social and environmental consequences; I also organize the university role and the relationship established between people and institutions which gave origin to the Agronomy course of UFPA and the programs developed in the region; conjuncture of creation of the groups of settled students, curriculum, principles and focus on the course and the experienced actions; developed practices in the course and the relations of reliability experienced internally and externally to the Academy, the learning and dialogue promoted by the course. I believe that the dialogue has caused changes in the organization of the knowledge and in the educative practices of the teachers, as well as, in the socio-productive practices of the regressed settled students

The study of caffeine in racing horses has been of growing concern in veterinary sports medicine since the Association of Racing Commissioners International (ARCI) stated that it has no valid therapeutic use in racehorses. We examined the kinetic alterations in the urinary excretion and salivary secretion of caffeine in seven horses subjected to urinary acidification using ascorbic acid because this procedure can simulate the acidosis that follows anaerobic exercise. They participated in two treatment groups: the control group (SG) received 500 ml of saline and then 2.0 mg kg(-1) caffeine i.v. 30 min later; and the acidified group (AG) was subjected to urinary acidification with ascorbic acid at a dose of 0.5 g kg(-1) i.v. and then 2.0. mg kg(-1) caffeine i.v. 30 min later. Samples were collected 30 min before caffeine administration, immediately before caffeine administration (time zero) and at 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 48 and 72 h afterwards. The samples were assayed by gas chromatography. The mean urinary pH for SG was 8.2, but for AG it was as low as 5.9 at 4 h, extending acidosis for up to 8 h. The kinetic curves for the two groups were similar for urinary excretion and salivary secretion. Differences occurred only in peak excretion and peak secretion in SG obtained at 1 h and 30 min, respectively, and in AG at 2 h and 1 h, respectively. This could be explained, in part, to the diuresis in AG compared with SG, resulting in less concentrated urine in the former group. The large difference between the pK(a) of caffeine and the pH of the medium may be responsible for the similar pharmacokinetics observed for the two groups. Copyright (C) 2004 John Wiley Sons, Ltd.

Caffeine is the legal stimulant consumed most extensively by the human world population and may be found eventually in the urine and/or blood of race horses, the fact that caffeine is in foods led us to determine the highest no-effect dose (HNED) of caffeine on the spontaneous locomotor activity of horses and then to quantify this substance in urine until it disappeared. We built two behavioural stalls equipped with juxtaposed photoelectric sensors that emit infrared beams that divide the stall into nine sectors in a 'tic-tac-toe' fashion. Each time a beam was interrupted by a leg of the horse, a pulse was generated; the pulses were counted at 5-min intervals and stored by a microcomputer. Environmental effects were minimized by installing exhaust fans producing white noise that obscured outside sounds. One-way observation windows prevented the animals from seeing outside. The sensors were turned on 45 min before drug administration (saline control or caffeine), the animals were observed for up to 8 h after i.v. administration of 2.0, 2.5, 3.0 or 5.0 mg caffeine kg(-1). The HNED of caffeine for stimulation of the spontaneous locomotor activity of horses was 2.0 mg kg(-1). The quantification of caffeine in urine and plasma samples was done by gradient HPLC with UV detection. The no-effect threshold should not be greater than 2.0 mug caffeine ml(-1) plasma or 5.0 mug caffeine ml(-1) urine. Copyright (C) 2001 John Wiley & Sons, Ltd.

O objetivo do presente estudo foi avaliar se a forma física da ração (farelada e peletizada) afeta a porosidade e espessura da casca, e porcentagem de perda de água e eclodibilidade de ovos de perdiz. Os ovos foram coletados logo após a postura e separados em diferentes intervalos de peso (35-45g, 46-50g, 51-55g, 56-60g e 61-70g), sendo 10 ovos/classe/ração. O número de poros das cascas foi avaliado nas regiões apical, equatorial e basal dos ovos. Utilizou-se um micrômetro digital para a mensuração da espessura das três regiões da casca dos ovos, a partir dos quais obteve-se a espessura média por ovo. Os ovos para avaliação da eclodibilidade e porcentagem de perda de água do ovo até a transferência para o nascedouro (16º dia) foram pesados, desinfectados, incubados (T=35,5ºC e UR= 70%) e transferidos no 16º dia de incubação para o nascedouro, onde foram mantidos até a eclosão. As análises estatísticas empregadas foram: Análise de Variância e de Correlação, e teste de Tukey 5%. Os dados mostraram que, em perdizes, o número de poros na casca pode variar com a região da casca, peso do ovo e a forma física da ração, e que a ingestão de ração peletizada promove um aumento na espessura da casca dos ovos sem alterar a eclodibilidade e a porcentagem de perda de água dos mesmos durante a incubação.

The aim of this study was to typify the skeletal striated fibers of the gluteus medius muscle of young Brasileiro de Hipismo (BH) horses by means of histochemical analysis with m-ATPase and NADH-TR according to the sex and the biopsy depth. It was observed that the frequency (F;%) and the relative cross sectional area (RCSA;%) of the fibers type IIX were greater than the fibers type IIA, which F and RCSA were greater than the fibers type I. The comparison between sex and muscles depht, showed no significant difference in F and RCSA in the three types of fibers. The results of morphometry showed that the gluteus medius muscle has greater glycolitic metabolism and anaerobic capacity because of the presence of large proportion of type IIX fibers. This may be justified by the genetic influence of Thoroughbred in the formation of Brasileiro de Hipismo breed.

A larvicultura da maioria das espécies de peixes enfrenta o desafio da dependência do alimento vivo (AL) e da falta de dietas formuladas (DF) que atendam plenamente às necessidades das larvas. A baixa digestibilidade e a qualidade nutricional das DFs são alguns dos fatores que explicam o insucesso quando as larvas recebem apenas FD. Para avaliar o efeito da combinação da DF com o AL no crescimento e na sobrevivência de larvas de jundiá (Rhamdia quelen), comparando com o uso separado da DF ou do AL, larvas recém eclodidas (5,57 mm; 1,41 mg) foram estocadas inicialmente em 12 aquários de 10 L (100 larvas por aquário). Quatro réplicas foram alimentadas ad libitum com uma das três dietas por 20 (para DF) ou 48 dias (para AL ou a combinação DF + AL). As larvas alimentadas com apenas DF apresentaram crescimento e sobrevivência reduzidos quando comparadas àquelas alimentadas com AL ou a combinação DF + AL. Adicionalmente, as larvas do tratamento DF + AL apresentaram maior crescimento em peso (170 mg) que aquelas alimentadas apenas com AL (110 mg). O melhor desempenho das larvas alimentadas com DF + AL mostra que a maioria dos nutrientes exigidos pelas larvas é fornecida mais adequadamente quando ambas as dietas são fornecidas juntamente. Contudo, trabalhos sobre nutrição larval poderão contribuir ainda mais sobre a elucidação deste tema quando feitas comparações com o uso combinado de DF + AL, do que apenas testando isoladamente novos ingredientes e fontes protéicas normalmente utilizadas na elaboração de dietas para juvenis e adultos.

At this investigation it was analyzed the content and the organization of the social representation on the object teachers education, built by teachers of degree courses from Universidade Federal do Piauí(Ufpi), understanding such representation articulated to the teaching habitus of these educators of teachers, what takes under consideration the position that they hold in the structure of the national field and in the subfield of teachers education. For that, it is searched: a) to emphasize the properties of the place in which the trainers act Ufpi as the office of those field and subfield; b) to understand who are the trainers, that is, to grasp the teaching habitus of the trainers with a view of its origin, social trajectory and the specifics of their position in the analyzed field and the subfield and c) to know what they think about their work object, that is, identify and articulate the content and the organization of the social representation analyzed with their properties of field and subfield agents. The research includes the specific degree courses of the Campus Ministro Petrônio Portella , from Teresina(PI), and it was applied to 134 professors of degree courses from this Campus. The data collect joined to the participants happened on the second period of 2008 and on the first semester of 2009. The starting point of the study is the corroboration that the reform of Ufpi degree courses, determined by the legislation and stablished at this Institution in 2005, altered a little the previous situation. It is comprehended that Ufpi and its structures of teachers education as a trainer institution, is limited by the national academic field and by the subfield of teachers education. From this last one, it was listed some of its properties, to show that it is about an academic subfield in construction process. It is emphasized division of the subfield, that separates the trainers into two subgroups the ones who dedicate themselves to the specific education on the contents and those ones who are specialized on pedagogical education placed in antagonistic position and competing by the symbolic power of imposing the meaning and the sense of the teachers education in the degree courses. To understand the comprehension of the problem, it is searched for the models that are in the root of the construction of the University and its project of teachers education in the degree courses, to clarify the matrixes in which the social representation searched is stablished. The theoretical referential articulates the contributions of Moscovici, the theory of social representations, and of Bourdieu, with the concepts that compose its praxeology, as habitus, social field, capital, symbolic power and others, as well as their interpreters and continuators, as Domingos Sobrinho. From the literature about the university and teachers education, it was used Dermeval Saviani, Luiz Antônio Cunha, Maria Isabel da Cunha and Mirian Jorge Warde, besides others. Plurimethodological procedures were adopted, combining associative techniques adjusted to the access to the social representations, and a classic technique, a questionnaire about teaching habitus. The condition is that the teachers build different social representation of the object teachers education because of the distinct positions that they occupy in the structure of the academic field and the subfield of the teachers education. The reached positions in the field and subfield are due to the differences in the origin and social trajectory of these agents, who, therefore, have different teaching habitus from which they build their social representation about their work object. It is highlighted that the teaching habitus and the social representation of two subfields, identified by the belongings to different dimensions of the teachers education in the degree courses, they have similarities and, also, differences. These ones permit to support that the subjects are holders of distinct teaching habitus that conceive different practices, struggles, tensions and conflicts around the sense of teachers education

This report aims to present the results of research on the possibilities and limits of Supervised Traineeship in a the course of Training of Teachers in Service of the early years of primary education conducted through an agreement between the Federal University of Piauí and the Teresina city council (PI) UFPI/PMT, offers subsidies to teaching practices that address the reality of students who live, work and/or studying in school located in rural areas. The research is based on a theoretical and methodological approach that places the object of study in the critical perspective and using procedures such as: literature (bibliographical research), documentary analysis, semi-structured interview and photographic record. We researched 10 (ten) teachers of the course promoted by UFPI graduating in 2006 and who develop teaching activities in schools located in rural areas in the city of Teresina-PI, 02 (two) teachers who are trainee supervisor of UFPI and the coordinator of the course. The analysis evidenced that the object, historically, educational policies have changed, but did not break the traditional patterns of teacher education, enough, especially in the curricular proposals in light of the changes required by the information and global society. We also note that in the supervised training, the process of critical reflection on teaching practice was made possible, in part, and raised the reconstruction of specific knowledge to make teaching in order to conduct the teaching-learning process articulating different realities of primary teaching and facing situations due to conservative practices in relation to education in rural areas. It contributed, therefore, this curricular component to resize, in part, the pedagogical action of the teachers graduated. The study also drives the research toward to similar studies in the perspective of overcoming the current model of teacher training that does not correspond to the demands of society in change and to the crisis of capital, with immeasurable consequences in the workplace. The contemporary claims for a University to form professionals capable of directing the destiny of society, where teacher training is a social and political demands on which is co-responsible

Objetivou-se avaliar em equino a influência do exercício progressivo e intenso realizado em esteira de alta velocidade sobre a temperatura de regiões da pele, incluindo face, pescoço e quartela, e do casco, incluindo coroa, parede e sola. Utilizaram-se cinco equinos Puro Sangue Árabes, desferrados, com idade média de 8±0,7 anos, sendo duas fêmeas e três machos, com peso corpóreo médio de 420±10kg. A intensidade de esforço foi determinada por meio da quantificação do lactato sanguíneo. As temperaturas foram determinadas com o auxílio de termógrafo, antes, durante e após o exercício. Realizou-se análise de variância seguida pelo teste de Tukey, sendo P≤0,05. A lactacidemia aumentou, principalmente nas velocidades intensas. Houve redução das temperaturas das regiões da face, pescoço e quartela após o exercício e diminuição das temperaturas da parede, coroa e sola do casco durante o exercício, enquanto a temperatura da manta de rolamento da esteira não se alterou em nenhum momento. Constatou-se indiretamente que a perfusão sanguínea do casco diminuiu durante o teste de esforço tanto em sua fase aeróbia como na anaeróbia. Nenhuma das intensidades de esforço foi capaz de alterar a temperatura da manta de rolamento da esteira. A temperatura do casco diminuída como decorrência fisiológica do esforço físico imposto, retornou aos valores normais após o término do exercício.

This paper analyzes the policy of upgrading the teaching profession in relation to financing basic education, with a view to participation of the Union of Education Workers of Rio Grande do Norte - SINTE / RN and the state government in the implementation of Professional Base Salary the National Professional Teaching Public Basic Education - Law 11738/2008, the public state of Rio Grande do Norte. The participation of civil society, through the union movement presents itself as an important process of implementation of Professional Base Salary. The participation of SINTE / RN occurred since the fight to pass the plan, careers and Compensation (2006) until the implementation of the Base Salary (2009) highlighting the power relations established between the Union and State Government. To this end, there were actions such as public hearings and strikes by education professionals. In order to raise issues relevant to the issue of enhancement of teaching and participation of unions as a collective representation has been taken as a theoretical and methodological literature on the financing of basic education, enhancing teaching and participation as well as policy guidelines governing the career of teaching. Was used as a methodological procedure to document analysis and information gathering through semi-structured interviews. The results indicate the participation and the power relationship between the trade union movement and the state government in the implementation of the Base Salary. However, the current issues concerning the limitations of recovery of the teaching profession in order to implement the policy floor, not only merit of the state of Rio Grande do Norte, but the decisions that have been taken by the Supreme Court (STF) relating to the unconstitutionality of Action (ADI) filed by five governors. This fact greatly reduced the possibility of recovery of the teaching of the state, considering that the government was limited to decisions of the Supreme Court. Therefore, the enhancement of teaching remains a challenge for the union movement

The study Teacher work and education in the municipal schools of Natal objectifies the analysis of the education and work conditions of the teachers in the municipal schools of Natal, placing them within the scenario of the public policies outlined for Basic Education (2005-2010). The thesis is based on the perspective that the educational reforms implemented by the Brazilian government in an attempt to answer to the new contextual demands originated from the world of work and globalization, demanding increasingly higher levels of qualification and constant extension of the teaching functions in school from the teachers, have been configured withal as a strategy for intensifying the teacher s work. The empirical field of study was constituded by thirteen municipal schools that offer basic education. Four hundred and seventeen teacher subjects that work in the municipal school system of Natal, two representatives of the Secretaria Municipal de Educação de Natal (SME)1 that work in the pedagogical team and one representative of the Sindicato dos Trabalhadores em Educação do Rio Grande do Norte2 took part in the study. The procedures/instruments used in the research were: bibliographic review, document research, questionnaires and recording of information in a field journal. The study confirmed that the majority of the teachers that work in the municipal school system were admitted by means of public entry exams, therefore meeting the requirements set by Law 9.394/96. Most of the teachers have the initial education demanded to work in basic education, although with some limitations due to the fact that they do not correspond to the needs of the educational system. The SME has a plan for continued training of the teachers in accordance to the current ideas defended by researchers of this field. There is, although, a disconnection between the purpose of the plan and the training strategies, because, in truth, predominate repetitive and specific actions that do not contemplate the training needs of the teachers, nor the demands of the system. Although the work conditions are evaluated, by the teachers, as relatively good, limits in relation to the physical structure of the schools are observed (dirty walls with holes in them, broken ceiling fans, old chairs and desks, old and stained black boards, inadequate restroom installations, poor maintenance of the computers, amongst other items). It was also verified the an increase in the functions of the teachers and an intensification of their work, materialized through an overburden of activities undertaken daily at school (and outside of it) and through the demand in taking part in activities that go beyond those inherent to the teaching process, such as the elaboration of political-pedagogical projects, participation in collegiate, registration of student information solicited by the SME and the participation in commissions, has been happening

The present study examined the relations of power in the management of the Escola Estadual Presidente Kennedy, including the deliberate decisions on the School Council and School Fund, which guided the organization of the school. We sought to understand the management models that influenced the school organization, promoting contradictions in the decision making process. The school management is intensely marked by management models from the business logics as in the case of managerialism of bureaucracy. The formulation of educational policies based on managerialism has proposed a school-centered management with intense accountability of the school community in planning and monitoring the public services. The influences of these models subsidize hierarchical power relations that undermine the actions of decision-making of the collegiate bodies for the democratization of school management. To develop a research on the power, the investigation was based on studies of Bourdieu and Foucault. These authors understand the power in a relational system in a double sense, both in terms of discipline and the possibility of resistance. A theoreticalmethodological matrix was developed focusing on literature review, document analysis, structured interviews with twelve representatives of the segments belonging to the School Council and School Fund, as well as observations in meetings with the production of field notes. It was found that power relations experienced in the organization and activities of the school boards are marked by changes in public management over the years, promoting the contradictions between the concepts of corporate management originated in the business logics and the perspective of democratic management subsidized by official legislative documents at the national and state levels. The observations in meetings and analysis of the records showed that representatives related to management (president and manager of the school) have a privileged position with regard to exposure of their propositions, and are more likely to take a position in the political game of the collegiate bodies of work. It was also seen that the irregularity of meetings, particularly of the School Fund meetings, limits the experience of operation of the representatives in discussions concerning the planning and monitoring the actions of school management. Reports from representatives of the School Council showed that certain segments related to the management recognize their power of decision, however others have little interfere in the decision-making process in order to expound the desires of those who are represented by them. In the School Fund, the analysis of the records and interviews showed restricted moments of the meeting of representatives, and these only being aimed at choice or approval of the implementation plan prepared by the school management. The results showed no indications of moments of reflection to study the best chance for applicability of resources. This collegiate body (School Fund) has a questionable action when planning and monitoring the applicability of the financial resources of the School. To sum up, it was found that the Escola Estadual Presidente Kennedy still lives hierarchical power relations that undermine the institutionalization of democratic management in the various representative segments may take place in the game of political decision-making processes necessary for the organization of the school

The regulation of gastric secretion is of crucial importance to the equilibrium of the gastroenteric system. Despite the large number of factors involved in the causes of peptic illnesses, pH = 4 is considered the threshold between physiologic and deleterious effects of stomach acid secretion. With the aim of maintaining pH greater than 4, proton-pump inhibitors, such as esomeprazole magnesium (NEXIUM), have shown excellent results in the control of acid secretion. Aimed at examining the action of this drug in the control of pH levels of gastric secretion in thoroughbreds, a single dose of 40 or 80 mg of esomeprazole magnesium was administered daily, and pH was determined serially for 5 consecutive days. The results obtained corroborated the efficacy of esomeprazole magnesium in the control of gastric pH at both doses tested, with 100% of the mean pH being greater than 5. Moreover, no statistical difference was noted between the two doses tested.
