Avaliou-se histologicamente a próstata de 30 cães adultos e idosos sexualmente intactos que apresentavam ou não sintomatologia clínica de doença prostática, e verificou-se a incidência de possíveis alterações da glândula. Dentre as alterações encontradas, a hiperplasia prostática benigna constituiu o diagnóstico mais comum, 85,6% (n=24), seguida por prostatite crônica, 64,3% (n=18), displasia do epitélio glandular, 42,8% (n=12), atrofia do epitélio glandular, 39,3% (n=11), infiltrado inflamatório focal, 25% (n=7), dilatação glandular focal, 21,4% (n=6), prostatite aguda, 7,1% (n=2), metaplasia escamosa, 3,6%, (n=1), metástase de neoplasia sistêmica, 3,6% (n=1) e abscesso prostático, 3,6% (n=1). Como em muitos casos os cães são assintomáticos, ressalta-se a importância da realização rotineira de exames clínicos específicos, como o toque retal e a ultrassonografia, para o diagnóstico precoce e o tratamento das afecções prostáticas.

El estudo que ahora apresentamos habla a respecto ala transformaçión de la Asociación de maestros del Rio Grande del Norte (APRN en sindicato de los trabajadores en educación (SINTE) en el período de 1986 1990. Tratase basicamiente de las razones que llebaran historicamente la APRN la reorganizar sus luchas, su cultura política y el su movimiento reivindicatório; que impulsionaran la construción del próprio sindicato el único de la categoria, após el regime militar em el país especialmente en el gobierno Sarney, y en el ánbito estadual com la resistência la política econômica y la repreción policial del gobierno Geraldo Melo, la época. El estudo también apunta algunas caraterísticas marcantes del contexto histórico de la educación nacional, enfatizando la asención de la escuela nueva en el Brasil en las décadas de 1920 y 1930, inclusive delante del movimiento sindical, controlado por el gobierno Vargas que tênia uma praetica corporativista. Es importante decir que esas características estavan juntas del contexto local, en el rato en que se percebia la primer gestan del prof Anfilóquio Cámara, como el primer presidente de la APRN, al partir de la su fundación (1920), y que tênia um relacionamento bastante estrecho com el poder público estadual de caráter liberal. Habia una discución sobre la abertura política y la atuación política de las clases médias brasileñas ya em 1979, y al mismo tiempo analisabase el desencandeamiento del nuevo sindicalismo en el ABC Paulista, mientras uno movimiento sindical, autônomo y democrático que tênia el objetivo de juntar lãs luchas de los operários dentro y fuera de las fábricas reivindicando basicamiente: la redución de la jornada del trabajo, reajuste de sueldo y condición del trabajo, bien como lãs sus consecuencias para el movimiento de los educadores potigurares. Al hacer en septembre de 1989, el sindicato de los trabajadores en educación del Rio Grande del Norte se desvincula definitivamiente de uma estructura sindical vertical (tradicional), que la ex-APRN herdo al longo de su História del gobierno Vargas, siempre controlada pelo Estado y que en las décadas de 1980 y 1990 fue fortalecido por la CNTE (Confederación Nacional de los Trabajadores en la, educación), principalmente, a partir del Congreso Nacional de Unificación de los Trabajadores en la Educación, realizado en Aracaju/SE em el período de 25 a 28 de enero de 1990 en el sentido tambien de las sus principais reivindicaciones: escuela pública, gratuita y de cualidades en todos los pasos, verbas públicas solamiente para las escuelas públicas, reposición de los reajustes de sueldo, condición del trabajo, sueldo unificado nacional y la eradicación del analfabetismo

Education and technology have always walked side by side. The Information and Communication Technologies are inserted in education as a profile of people from the new era. This research has the objective of understanding the insertion of the use of the Technologies of Information and Communication within the educational context, from the analysis of the process of interactivity among students and teachers of the Portuguese distance course of the Tiradentes University (Unit). For such, the empiric investigation was based on the analysis of academic documents, such as: the Course Pedagogical Project and Class Planning of regular classes, in regular classrooms, as well as interviews, focal groups, and pictures with people who live the history of the course. Direct observations were also conducted. The methodology applied was bibliographic and qualitative research of the exploratory type, using the information that was collected through the interviews. The results of this research demonstrated that the interaction promoted by the ICT represents a process of social change, and therefore, of development for education. It was concluded that the Distance Education has to overcome some fragilities, aiming at contributing to the educational field and to the promotion of interactions among students

This thesis is a translation of work of the Brazilian doctor, Pedro da Silva Nava (1903-1984), in particular, his memoirs and chronicles, articulated with the writings of medicine history, aiming to defend that the autobiographical narratives are sources of research capable of promoting discussions on the expansion of the present at the confluence of complex and unequal society in constant changing process as the Brazilian. The theoretical and methodological support circulates around studies, proposals and thesis by Boaventura Santos about empowering past, destabilizing subjectivity, sociology of absences, cosmopolitan reason and translation work. The empirical support drawn from the literature produced by Nava were analyzed with reference this reasoning and studies that have facilitated the flow of translation among others, the studies of Antonio Candido, Arrigucci Jr., Boris Cyrulnik, Beatriz Sarlo, Ecléa Bosi, Ítalo Calvino, José Willington Germano, José Maria Cançado, Lev Vygotsky, Marilena Chauí, Paul Ricöeur and Walter Benjamim, without neglecting what we consider indispensable to scientific research, the production of relevant knowledge and prudent, in view of a decent life. The initial inflections reflect the subject of the Memoirs and its education/training, to then place the Memoir subject in the literary context, scientific, historical and Brazilian poetic (1972-2010), bringing great interpreters and discussing the rationale used by the Narrator that we defend stand closer to the cosmopolitan, showing the formation of narratives whose presence insert itself beforehand to modernist verve, linked to the discursive array against the literature as domination space, disseminated in Brazil in the early twentieth century. So, it articulate with those in which the concerns adjust the construction of the social formation of Brazil as a national heritage through literary narrative that focuses on a historical principle that becomes the past empowering, allowing his rereading, whose converge to memory, the lifestyles, the plurality of language and Brazilian culture, formed by several people, converging into a design not of culture but multiculturalism in Brazil. The memory issue was addressed in the space-time of experiences of being that narrates, shaped by a destabilizing subjectivity that sought to order the testimony of a time, a history and society, retelling them by creative imagination, almost fictional, to make circulate his knowledge about Brazil attached to his medical knowledge, as well as other subjects in his living group and other groups with whom they maintained contact. Thus, he portrayed both tangible and intangible cultural assets of the country as a form of preservation, giving them meanings and sense. It approaches, therefore, from the perspective of sociology of absences, the expansion of the present and by the logic inherent in his narratives of self and Brazil

Dois casos de displasia da valva tricúspide são relatados neste trabalho. Os cães foram avaliados devido à fraqueza e presença de ascite. em ambos os casos, o exame ecocardiográfico mostrou insuficiência tricúspide e, em um deles, a inserção dos folhetos da valva tricúspide encontrava-se deslocada para baixo do ventrículo direito, caracterizando a anomalia de Ebstein. A terapia medicamentosa para insuficiência cardíaca congestiva foi iniciada, mas um dos animais veio a óbito subitamente alguns dias após o diagnóstico. O outro cão, apesar de inicialmente ter apresentado melhora significativa do quadro clínico, apresentou morte súbita. A necropsia dos animais revelou dilatação atrioventricular direita e folhetos tricúspides espessados. As características clínicas, métodos de diagnóstico e terapia medicamentosa são discutidas neste artigo.

Studies on the effects of changes in biodiversity and ecosystem functioning have been a central theme in ecology over the past two decades. Several studies have showed that the diversity of plant debris differently affects the decomposition process in aquatic and terrestrial environments, but we know very about the effects of detritus diversity on decomposition under fluctuating environmental conditions. We tested whether and how the environmental contexts, as well as the dynamic of their alternation, influence the effects of detritus diversity on the decomposition process. We performed a field experiment where we manipulate the litter diversity of 8 species of terrestrial plants decomposing (litterbags) in single and in mixture containing the eight species together in three different environmental contexts: the terrestrial environment (T), aquatic (A) and interface (I) - experimental treatment that simulates variation in flooding regime. We measured the rate of decomposition through the loss of mass of the community and each individual detritus in monocultures and mixtures. Species richness and environmental variability had no effects on the magnitude and stability of the decomposition process. However, there were significant diversity effects on the decomposition of an individual alien species, F. benjamina. Environmental context had significant effects on the magnitude and variability of decomposition. Detritus decomposition was faster and more variable on aquatic, interface and terrestrial conditions, respectively. Our results demonstrate that the diversity of plant detritus has minor effects to the decomposition across disparate environmental conditions and suggest that it is necessary to consider the potential of other abiotic factors in affect the magnitude and variability of the decomposition processes

This study The Dyad of knowledge and teaching practices: an inter-relational study deals with the relationship between conceptual knowledge on behalf of the teachers and their teaching practices. The research aims to investigate the relations amongst conceptual meanings related to the professor and the practices of three (03) Fundamental Cycle public schools teachers in Natal-Brazil. Thus, a collaborative research of qualitative nature was performed by us. It was based on collaboration and critical reflection, as well as the socialhistorical theoretical methodological principles of Ferreira (2009). This was acknowledged as an analytical support for the reflections that were realized on concepts related to teachers and teaching considering the archeology on these concepts. The methodological procedures and tools we used consisted of Formative Autobiographies, Reflexive Study, Collaborative Observation, as well as some Reflexive Sessions. The analysis framework was based on information obtained by these methodological procedures as well as the critical collaborative and reflexive procedures. The studies permitted us to widen our knowledge related to the conceptual meaning of teaching and teachers. But it was not always possible for us to (re)elaborate these meanings in the conceptual phase. This was only possible to understand once our Formative Autobiographies were analyzed. They reveal that the concept elaboration process is not a part of our own formative path. The time that was dedicated to that proved to not be enough. The concept elaboration process demands time, effort as well as life-long learning skills. This is not always possible to achieve in this part of the study, on the other hand, this was possible to acknowledge that in the different stages of our conceptual elaboration. The teaching practices that we analyzed were predominantly heterogeneous and were fundamented on meanings of concepts related to teachers and teaching, that were internalized beforehand, (re)elaborated according to the conflicted and contradictory situations. The reflexive and collaborative process that we experimented during the Reflexive Sessions pointed out the predominance of technical and practical reflection process. In some moments it was possible for us to critically reflect on teaching practices due to the collaborative mode that we experienced. The importance of collaboration for teaching formation and professional development of behalf of teachers in general is pointed out by this research. Also regarding this research it was possible to see that there was personal and professional growth, experiencing learning together to collaborative reflect, as well as to counter-argument, reformulate concepts and conceptions aiming to transform our teaching practice

Study about the national politics on the professional education, under responsibility of the brazilian Work Department in 1990 years. Purposes to apprehend the results of the actions of the professional education in a basic level, offered by the National Plan of the worker qualification ( PLANFOR ), as well as the effects on the assisted exits, starting from the experience appreciated on the Plan of Qualification developed in the state of Maranhão between 1996 to 2000. It adopts a theoretical-methodological conception by an ontological nature, if being worth of categories as the one of totality and of mediation that together, makes possible the apprehension of a dialectical movement that happens among the analysis object, the professional education politics in a basic level, performed by PLANFOR and your context, the underdevelop and heterogeneous Brazilian capitalism and the consequent job market generalized precarious and informal, making possible that the reality investigated become to understood rationally. This paper uses the indirect documentation technique, instruments of the bibliographical research and documental research. This study is based on those that aren´t part of PLANFOR, qualified by professional education courses in basic level,they didn't get to be inserts at the formal job market, just occupying precarious occupations in the informal job market. Aims to presents and discusses the productive process and your restructuring globally in progress. It focuses at the impacts on the workers, the precariousness of the work that appears like a new phenomenon calls new informality. Talks about the particularity process of productive restructuring assumed in Brazil highlights, showing that the informality, was always a structural phenomenon in the country. Discusses about the professional qualification in the contemporary capitalism, specifying some of your theses. Shows in a historical view the process of appearance of the employment notions and competence, and the influence that it exercised on the reforms of the basic and professional education, as well as the implications of both in the politics of professional education in the country. Rescues the process of creation of PLANFOR, your official formulations and your organized bases, starting from the second half of the 1990 decade. Shows yet the continuos changes in the job market of Maranhão state, for after, starting from the reports expresses at the Plans of Qualification from the state, elaborated by the Group of Evaluation and Studies of the Poverty and the Politics addressed to the poverty from the Master degree Program in Public Politics, from the Federal University of Maranhão, analyzing the acting of PLANFOR in the State, your probable deficiencies, as results the changes verified in the conditions of occupation and the gains of the exits from the professional education courses in basic level

Realizou-se análise histológica de brânquias de 15 espécimes de Piaractus mesopotamicus e 19 Prochilodus lineatus coletados de abril a novembro de 2004, no Rio Aquidauana, MS, com intuito de contribuir com achados anatomopatológicos em brânquias dessas espécies de peixes de água doce. Amostras de brânquias foram fixadas em formalina 10%, tamponadas e processadas conforme rotina histológica. em P. mesopotamicus observou-se presença de monogênea e cistos de mixosporídio da espécie Henneguya piaractus, com localização intralamelar em vários estágios de desenvolvimento, localizados em todas as regiões (basal, mediana ou distal) das lamelas. Cistos intraepiteliais causaram dilatação e deformação das lamelas vizinhas. em brânquias de P. lineatus, observou-se presença de monogênea. Nas duas espécies de hospedeiro foram registradas hiperplasia do epitélio branquial e desorganização estrutural das lamelas em extensas regiões, alterações que causaram a fusão lamelar. em poucos casos registrou-se presença de células inflamatórias mononucleares e focos hemorrágicos na região distal das lamelas.

This research aims to study the participation of mothers in the School Council of the Centro Municipal de Educação Infantil Amor de Mãe. The goal is to understand the relationship among concepts that mothers have and their practices as advisors. The historical-philosophical approach taken along the research permitted working with real people and not those derived or idealized ones. It searched an approximation of the mode of being and living of the councilor mothers in their homes, and the concepts and practices in the School Council. It was inspired by ethnographic researches to describe data, habits, cultural practices, meanings and values of people involved. As sources of research, we used: interviews with mothers and school staff; documentary and photographic collection of CMEI Amor de Mãe; local and national legislation; notebooks of the National Program for the Strengthening of School Council (2004); data bank of dissertations and theses of the Post-Graduate Program in Education of the UFRN dealing with democratic management and the relationship school and family. The study indicates the existence of a narrative of the school community that shows mothers as "missing" or "passive" and a practice that point out to how people participate actively in the school routine. This contradiction reveals the existence of a historically constructed school mindset that is rooted in a model of family and school that differs from the reality found in CMEI Amor de Mãe and how families served by CMEI Amor de Mãe organize themselves. It is recommended that the school community and families reorganize the conceptions that guide their practices in educating and caring for children with whom they live and work to make progress together in managing this process

Visando fornecer subsídios para elaboração de sistema de manejo integrado das grandes massas de plantas daninhas aquáticas submersas em lagos e represas, o presente trabalho teve como objetivo verificar a eficiência do pacu (Piaractus mesopotamicus) como agente de controle biológico de Egeria densa, E. najas e Ceratophyllum demersum. As espécies de plantas daninhas foram oferecidas individualmente, duas a duas e as três espécies juntas. Verificou-se que este peixe tem uma eficiência média de controle dessas plantas daninhas variando entre 28 e 100%, podendo eliminar uma massa verde dessas plantas, com a mesma quantidade de seu peso, em sete dias. A eficiência de controle diária aumentou com o tempo de predação. O pacu é mais seletivo para E. densa ou E. najas quando na presença de C. demersum. Não ocorreu alteração na eficiência de controle do pacu sobre E. densa ou E. najas em todos os tratamentos e nos três períodos estudados (três, cinco e sete dias).

The Knowledge Management in organizations is a continuous process of learning that is given by the integration of data, information and the ability of people to use this information. The Management Skills is concerned to understand the powers of officials in the face of organizational skills (teams) and professionals (or tasks positions) want. Joints are located in the greater context of the economy of organizatio s and have the same assumption: that the possession of scarce resources, valuable and difficult to imitate gives the organization a competitive advantage. In this sense, this thesis proposes a model of knowledge management based on analysis of GAP of powers, namely the gap between the skills needed to reach the expected performance and skills already available in the organization, officials and trainees of Coordination of Registration of conductors of DETRAN-RN. Using the method of survey research could make an analysis of academic skills, techniques and emotional individual and a team of officials and trainees, identifying levels of GAP's competence in that sector of the organization and suggest a plan for training , A level of expertise for each sector of coordination, and propose a model for Knowledge Management to help the management of GAP's identified

This work present a interval approach to deal with images with that contain uncertainties, as well, as treating these uncertainties through morphologic operations. Had been presented two intervals models. For the first, is introduced an algebraic space with three values, that was constructed based in the tri-valorada logic of Lukasiewiecz. With this algebraic structure, the theory of the interval binary images, that extends the classic binary model with the inclusion of the uncertainty information, was introduced. The same one can be applied to represent certain binary images with uncertainty in pixels, that it was originated, for example, during the process of the acquisition of the image. The lattice structure of these images, allow the definition of the morphologic operators, where the uncertainties are treated locally. The second model, extend the classic model to the images in gray levels, where the functions that represent these images are mapping in a finite set of interval values. The algebraic structure belong the complete lattices class, what also it allow the definition of the elementary operators of the mathematical morphology, dilation and erosion for this images. Thus, it is established a interval theory applied to the mathematical morphology to deal with problems of uncertainties in images

This work presents the development of a prototype of an intelligent active orthosis for lower limbs whit an electronic embedded system. The proposed orthosis is an orthopedical device with the main objective of providing walking capacity to people with partial or total loss of lower limbs movements. In order to design the kinematics, dynamics and the mechanical characteristics of the prototype, the biomechanics of the human body was analized. The orthosis was projected to reproduce some of the movements of the human gait as walking in straight forward, sit down, get up, arise and go down steps. The joints of the orthosis are controlled by DC motors equipped with mechanical reductions, whose purpose is to reduce rotational speed and increase the torque, thus generating smooth movements. The electronic embedded system is composed of two motor controller boards with two channels that communicate with a embedded PC, position sensors and limit switches. The gait movements of the orthosis will be controlled by high level commands from a human-machine interface. The embedded electronic system interprets the high level commands, generates the angular references for the joints of the orthosis, controls and drives the actuators in order to execute the desired movements of the user
