Intensive production of tilápias, in cages or net tanks, has been proposed as an alternative to increase fish production, that would generate income and offer animal protein in different tropical and subtropical countries. However, this system of production enriches the aquatic environment with nutrients, principally nitrogen and phosphor derived from the dejections of the metabolism of food and eventual food surpluses consumed by the fishes; the alimentation of the fishes in this production modality is dependent on fish food. The emission of these nutritions in levels above the limit that the system is capable metabolize can provoke a phenomenon called eutrofization, putting in risk the quality of water for public and for fish production activities. In this context the work had as a goal to evaluate the trófico state of the four reservoirs for intensive production of tilapias in net-tanks, in other words, he maximum fish production that the reservoirs are able to hold, keeping the desired quantity of nutrient concentrations in water for public use. The results of the four ecosystems in the Boqueirão de Parelhas reservoir showed that it s possible to have an intensive production of tilapias in net tanks, in this environment the annual average concentration of phosphor, was below the considered critical limits to deflagrate the process of eutrofization in semi-arid regions. The carrying capacity of the Boqueirão de Parelhas reservoir depends on the conversion of the feeding facts and phosphor content in the food but it should vary between 100 and 300 tons per year over a variation in the conversion feeding factor of 1,7 to 2,0:1 and a variation in the P in the food of 0,7 to 0,9%

Difusive processes are extremely common in Nature. Many complex systems, such as microbial colonies, colloidal aggregates, difusion of fluids, and migration of populations, involve a large number of similar units that form fractal structures. A new model of difusive agregation was proposed recently by Filoche and Sapoval [68]. Based on their work, we develop a model called Difusion with Aggregation and Spontaneous Reorganization . This model consists of a set of particles with excluded volume interactions, which perform random walks on a square lattice. Initially, the lattice is occupied with a density p = N/L2 of particles occupying distinct, randomly chosen positions. One of the particles is selected at random as the active particle. This particle executes a random walk until it visits a site occupied by another particle, j. When this happens, the active particle is rejected back to its previous position (neighboring particle j), and a new active particle is selected at random from the set of N particles. Following an initial transient, the system attains a stationary regime. In this work we study the stationary regime, focusing on scaling properties of the particle distribution, as characterized by the pair correlation function ø(r). The latter is calculated by averaging over a long sequence of configurations generated in the stationary regime, using systems of size 50, 75, 100, 150, . . . , 700. The pair correlation function exhibits distinct behaviors in three diferent density ranges, which we term subcritical, critical, and supercritical. We show that in the subcritical regime, the particle distribution is characterized by a fractal dimension. We also analyze the decay of temporal correlations

Brazilian Psychiatry Reform, through Psychosocial Care Strategy, has intended to build insane people care practices from community care services which contemplates the subjects complete lives. However, to change the traditional care ways demands the facing of a series of epistemological, political and cultural obstacles. One of the current challenges deals with patients aggravation processes, with management ways, with devices and with professionals, as well as with the assistance network. The purpose of this thesis was to investigate how these aggravation processes has been constituted in Natal mental healthcare network, understanding its effects in the work teams and patients. Theoretical and methodological perspective used was Institutional analysis was, subsidizing the usage of concept-tools as the implication analysis, selfmanagement and self-analysis, and restitution. The research was carried out at the Natal East Sanitary District Mental Healthcare Clinic, with the participation of technicians and patients. The research procedures were: literature and document research on the attendance and the analyzed theme; attendance registers analysis; participating observation of the institutional routine for three months and field log entries; talking groups, one with the team and one with the patients. Two main discussion points are shown: 1. The mental healthcare clinic organization logic and the intersector politics; 2. The work and management processes developed at the mental healthcare clinic. The analysis show diversity in the attended demands in the service, which has favored the patients aggravation, this device and the substitute network processes. The work processes are apart from the political sphere and from the managements processes. In this sense, we show the need to reevaluate the clinic device as well as the management models adopted in the Brazilian Psychiatry Reform context

Este estudio analiza los efectos de la política de financiamiento de la educación básica, por intermedio de los Fundos contables, Fundef y Fundeb, y su proposición en valorar el magisterio, considerando las dimensiones de carrera y de la remuneración de los profesores de la red pública estadal de enseñanza del estado de Rio Grande do Norte, en el período entre 1996 y 2010. Para entender las condicionantes de la evaluación de las políticas públicas, se buscó también las contribuciones de Marx (1996) segundo quién “el concreto es concreto” y que la dialéctica del concreto se puede auxiliar en el intento de captar el fenómeno estudiado. Se utilizó aún, el referencial teórico bibliográfico relacionado al financiamiento de la educación y a la valoración del magisterio, a partir de la literatura referente a las dimensiones del objeto (fundef y Fundeb) y (carrera y remuneración). En la investigación documental, además de las legislaciones, directrices nacionales y locales pertinentes, se utilizaron datos referentes a los recursos disponibles en la Finbra. Tesoro Nacional, SIOPE/RN, INEP/MEC, datos de resumen del folio y folio de pagamiento de Secretaria de Estado, de la Educación e de la Cultura (SEEC), y 289 sueldos de 21 profesores. Se realizó entrevista semi estructurada con nueve profesores, referente a la carrera, además de un cuestionario aplicado a 12 profesores relacionado a remuneración. Se considera que en los resultados referentes a los indicadores educacionales, en el período Fundef ocurrió una reducción en las inscripciones de la red pública de enseñanza, como también en las funciones docentes, de la enseñanza base (fundamental), que corresponde a 37%. A partir de la vigencia del Fundeb (2007 – 2010), estos indicadores fueron puestos en ecuación. En todo el período entre 1996 a 2010, ocurre un aumento en las inscripciones de 119,03% y en las funciones docentes de 77,44%. Sobre los datos de financiamiento, se constató que, del mínimo exigido (60%) en la aplicación de recursos de los Fundos en la remuneración del magisterio se aplica en el período de los dos Fundos, pero el mínimo exigido, o sea, 83,29% a 98,89% de los recursos. Los efectos de los Fundos en la carrera de los nueve profesores, considerando la promoción y la progresión, no han sido satisfactorios. En la promoción de los nueve de estos docentes, apenas uno evolucionó el Nivel (titulación), pero retrocedió en la progresión. En la progresión de los nueve profesores, ocho se hallan con la progresión retrasada, entre dos y cinco clases, acumulando un perjuicio que varía de 10% a 45% en su ganancia. La diferencia de una clase a otra corresponde a 5% en la renta anual. Se observa que las ventajas pecuniarias contribuyen con la remuneración con porcentaje más alto que la renta, disminuyendo esta diferencia en el período de Fundeb. Sobre la remuneración, un profesor con 24 años de carrera, con formación (magisterio), no consigue, después de años de profesión, ganar ni siquiera dos salarios mínimos. El profesor con 30 años de carrera, con maestría, tiene una renta, en 2010, correspondiente a menos de tres salarios mínimos, o sea, 2,82 y una remuneración que equivale a poco más de tres salarios mínimos, o sea, 3,66. Si comparamos la profesión de magisterio con otras que igual exigen formación superior, la primera es, en general, de bajo nivel, causando un resultado negativo sobre la búsqueda de la profesión del magisterio. Por los efectos en la remuneración, se concluye que hubo una mejoría, pero aún insuficiente, sobre todo al comparar con el Salario Mínimo Anual. Se evalúa, una vez que los fundos – Fundef y Fundeb – no fueron capaces de promover la valoración del magisterio en las dimensiones de la carrera y de la remuneración. Se constatan algunos resultados negativos en la política de Fundo ya que tendría que ver, principalmente, con la incapacidad de la referida política a valoración de magisterio, siendo una de las causas, o financiamiento con restricción de presupuesto.

The results of the research systematized on this analysis sought apprehend the linkage of the socio-educational service network, destined to adolescents who comply with socioeducational measure of confinement, in the region of the Seridó of the state of the Rio Grande do Norte, especially in the city of Caicó, central town of this region. The achievement of this study was stimulated by the interest in unraveling the contradictory reality imposed by neoliberal State, sparing the guarantee of rights, especially to these teens, who are seen as authors of violations and are stigmatized by capitalist society. The research was carried in the period July-September 2013, under critical perspective, using the documental analysis and the observational techniques and interviews with professionals of the Educational Center (CEDUC), of the Unified Health System (SUS), of the Social Policies of Social Assistance, and of the State Department of Education, which should make the service network that gravitates around the National System of Socio-educational Services (SINASE). The Statute of Children and Adolescents (ECA) and SINASE define that the application of socioeducational measures cannot occur isolated of the public policies, becoming indispensable the linkages of the system with the social policies of social assistance, education and health. However, it was observed that the neoliberal logic of the capitalist State has developed broken, disconnected, focal and superficial social policies, who fail give effect to the rights acquired beyond the legal sphere. In this perspective, it is possible affirm that the everyday of the Brazilian poor teens is marked by the action of the State, which aims to control those who disturb the order of capital, who threaten the production, the market, the consume and the private property. This way, actions are promoted criminalizing poverty and imprint a legal action over this expression of the social issue to the detriment of social policies that meet the real needs of adolescents. Face of this reality, it becomes necessary to put on the agenda of the here and now to fight for rights, aiming at a broad public debate involving professionals, researchers and social movements in support of the viability of rights, which aims to support reflections and to strengthen ways to confront this social problem. With the approximations of this study, it was learned that the struggle for rights is a fight for another project of society, beyond what is laid.

The current research developed in the Federal Institute of Paraíba – IFPB, João Pessoa Câmpus, aimed at analyzing the inclusion of students with disabilities in undergraduate courses based on the TEC NEP Action. It departs from the discussion about professional and special education in an inclusive perspective, focusing on people with disabilities, in the social context of these two modalities of education, considering the world scenario and the current Brazilian educational policy. It discusses the TEC NEP Action within the national and local context through the analysis of the official documents with the objective of getting familiarized and evaluating the process of educational inclusion in the IFPB João Pessoa Câmpus. The theoretical reference used contributed to the analysis of the policy which focused on inclusion in federal undergraduate institutions for professional education. The methodology used presents a qualitative analysis, having as subject of the research students with disabilities from undergraduate courses in the IFPB João Pessoa Câmpus who are supported by NAPNE. The results based on the analyzed data show that volunteer students from this research evaluate their process of inclusion in the appointed institution as positive, in spite of challenges specially the ones related to architectural barriers. It is concluded that the foundation of the House for Supporting People with Special Education Needs – (NAPNE) through the TEC NEP Action had crucial importance in the basis for the discussion about inclusion in the institution, widening the vision towards the demands of students with disabilities in order to facilitate access, permanence and academic success of these students.

The study aims to evaluate the performance and identify lesions of agonistic interactions of Macrobrachium rosenbergii in different densities cages (chapter 1); compare the growth performance of shrimp M. rosenbergii and Litopenaus vannamei cages (chatper 2); in addition the study aimed at identifying the knowledge and practices of a traditional community of farmers Bebida-Velha, in the city of Pureza / RN, practicing rural family and aquaculture, as well as tracing the community socioeconomic profile and evaluate the management that these farmers use in shrimp farming Macrobrachium rosenbergii (chapter 3). To perform the experiments (chapter 1 and 2) shrimp species L. vannamei and M. rosenbergii were weighed on a digital scale and transferred to cultures in cages. The cages had 1m³, with 5mm mesh between us and were closed on top with screen to avoid predators (birds, insects). The animals remained in adaptation for fifteen days before the start of data collection (each experiment). Both experiments lasted seventy days, totaling eighty-five days cultivation. During the cultures, animals were fed pelleted feed for shrimp at 10% of their biomass with 35% crude protein, offered in feed trays twice a day during the hours (7:00 am and 14:00 pm). The remnants in the tray were removed after 2h of permanence to calculate intake. To determine the performance parameters, some samples were taken every 10 days. The results of both experiments were analyzed using the STATISTIC 7.0 (2004). In Chapter 1 experiment were applied5 treatments were applied with 5 replications each: D5 - 5 animals/m2 ; D10 - 10 animals/m2 ; D15 - 15 animals/m2 ; D20 - 20 animals/m2 ; D25 - 25 animals/m2 . To this, were distributed 25 cages randomly in two masonry nurseries. The end of the experiment the lesions were verified and quantified. The chapter 2 experiment began when the shrimp reached the same age (eighty-four days) and was used the density of 25 shrimp / m2 with 4 repetitions. For the realization of chapter 3 were applied semi-structured interviews by direct approach of Bebida Velha of settlers practicing aquaculture activity, tilapia producers and community shrimp. Data were tabulated and analyzed according to the responses obtained by the participants. Therefore, the amount of damage increased with increasing stocking density. The density of 10 freshwater shrimp/m² showed the best conditions for a better performance in cages. It can be concluded that in cages, the cultivation of species of fresh water shrimp M. rosenbergii had better zootechnical indexes than the cultivation of marine shrimp species L. 9 vannamei. It was possible to verify that the activities of which the interviewees practice guarantee a good quality of life and income for them. We find that respondents have traditional and local knowledge, and also may be interested in the cultivation of the species M. rosenbergii.

This study is about the enhancement of the elementary school in Natal/RN, (PCCR - Law No. 058/2004), concerning to the horizontal promotion through the performance evaluation. It uses as reference the education policy on the legislative field hegemony and the managerial model. The analysis of the teacher´s valorization is based on the policy of Funds (Fundef and Fundeb) in the Brazilian social and educational agenda. The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010).The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010). The thesis argues for the necessity to adopt a direct relationship between career development and horizontal promotion for more others fifteen classes, no matter to any conditioning variables. In addition, the performance shall be evaluated by interval of 25 years to reach at least the provisions decided in the law, which determines the salary adjustment in 5% at every two years, as pointed at the PCCR, about teachers remuneration, and teachers qualifications. A work of a bibliographic and a documental review about the education funding with the purpose of enhancement of educational work, career concepts, and also promotion and evaluation performance as well was performed based on experts authors in this field. The survey was organized with the aim of articulating quantitative and qualitative information, analyzing data from the teacher's salary - payrolls and paychecks - also applying a questionnaire. After the implementation of the PCCR, it was found that the wage indices for horizontal promotion during the teaching career are tied to a strategy for evaluating the performance which disqualifies the teacher‟s salaries in a minimum percentage of 25% (up to 25 years) and there are also elements that disturb the promotion strategy. The national minimum wage was set in three salaries by the PSPN Lei nº11.738/2008 but it never reaches the three salaries at Natal/RN educational system.Otherwise, the elements that structure the horizontal promotion in fifteen classes, throughout the career, flout the minimum years of teaching work, long established in 25 years. In addition, changes in terms in the salary increase depend on individual efforts by professional development through titration. Concerning to the career, despite of the category approving its PCCR, neither this instrument nor the Funds Policy managed to establish regulations were able to cope effective rules for valuing the teachers in the educational district system. It is necessary to ensure, in percentage terms and financial, the real remuneration of teachers with the attainment of horizontal promotion, reviewing the elements that structure the career and the determinants of performance evaluation.

Este trabalho se debruçou sobre a produção audiovisual das movimentações de protesto ocorridas em Natal, capital do Rio Grande do Norte, entre maio e junho de 2011, denominadas #ForaMicarla. Objetivou-se caracterizar esta produção numa tentativa de responder o porquê e como eles lançaram mão do vídeo em suas ações, sob as hipóteses de que a midiatização e o acesso facilitado a estas tecnologias tinham a ver com suas opções. Lançou-se mão de procedimentos histórico-dialético e teoria fundamentada (Fragoso, Recuero e Amaral), a partir das técnicas de observação não-participante, aplicação de questionário e entrevistas em profundidade. Posicionou-se estas movimentações sociais em redes, na conceituação de Castells, dentro de uma perspectiva da contra-hegemonia como uma Mídia Radical (Downing), sendo um Audiovisual de Combate (Bustos). Esta mídia possui as características do Novo Protesto (Assis), inserido no contexto da midiatização da sociedade de Verón e Sodré. Tentou-se também identificar historicamente as origens do poder hegemônico e a estrutura oligárquica, coronelística e familiar que fundou o poder no Brasil, apropriando-se do conceito de Coronelismo Eletrônico de Lima e Lopes e Assistencialismo Midiático de Guareschi, Dias e Hartmann. Através dos dados obtidos houve a emersão das categorias para análise deste tipo de audiovisual.

Generation systems, using renewable sources, are becoming increasingly popular due to the need for increased use of electricity. Currently, renewables sources have a role to cooperate with conventional generation, due to the system limitation in delivering the required power, the need for reduction of unwanted effects from sources that use fossil fuels (pollution) and the difficulty of building new transmission and/or distribution lines. This cooperation takes place through distributed generation. Therefore, this work proposes a control strategy for the interconnection of a PV (Photovoltaic) system generation distributed with a three-phase power grid through a connection filter the type LCL. The compensation of power quality at point of common coupling (PCC) is performed ensuring that the mains supply or consume only active power and that his currents have low distorcion. Unlike traditional techniques which require schemes for harmonic detection, the technique performs the harmonic compensation without the use of this schemes, controlling the output currents of the system in an indirect way. So that there is effective control of the DC (Direct Current) bus voltage is used the robust controller mode dual DSMPI (Dual-Sliding Mode-Proportional Integral), that behaves as a sliding mode controller SM-PI (Sliding Mode-Proportional Integral) during the transition and like a conventional PI (Proportional Integral) in the steady-state. For control of current is used to repetitive control strategy, which are used double sequence controllers (DSC) tuned to the fundamental component, the fifth and seventh harmonic. The output phase current are aligned with the phase angle of the utility voltage vector obtained from the use of a SRF-PLL (Synchronous Reference Frame Phase-Locked-Loop). In order to obtain the maximum power from the PV array is used a MPPT (Maximum Power Point Tracking) algorithm without the need for adding sensors. Experimental results are presented to demonstrate the effectiveness of the proposed control system.

This study approaches bureaucratic organizational structures with the aim to understand the adherence procedure to virtual technologies in the stricto sensu educational administrative process. Thus, the author navigates through the formation of these organizations in Brazil with the intent to demonstrate the bureaucratic organizational culture and the consequent form of domination of those who detain power. In this epistemological construction, the author explores the culture s bureaucratic environment and the organizational power. In the analyses, it was observed the technological phenomenon in the ODL s administrative environment, which can explain the adherence procedure to structures and technological instruments for stricto sensu courses that, hypothetically, dilutes the traditional inherited organizational axiom. Therefore, it was utilized as object of study the Professional Master s degree in National Scale Public Administration PROFIAP, hence analyzing the documental content and the legislation related to institutionalization as well as the positioning of professors/coordinators and of the director of CAPES/MEC. Considering this axioms, it was concluded that the bureaucratic structures can admit ODL in the stricto sensu s environment. However, this can only be done as long as the adherence does not imply in a dilution of the traditional forms of power and institutional bureaucratic inherited dominance, as well as the alleged hegemony of the governmental structure in the educational administration adopted in person by the stricto sensu courses in Brazil

As peculiaridades presentes no ser humano são observadas a partir da manifestaão de sua cultura. Estas manifestaões podem ser influenciadas pelo contexto social do indivíduo. A cultura nacional é uma destas influências. A brasileira, por exemplo, possui alguns traços nacionais peculiares ao seu povo que amenizam a sua complexidade e pluralidade. Estes traços podem se tornar influentes na cultura organizacional, através da manifestaão das práticas e dos valores utilizados pela organização. Diante disso, o presente trabalho teve como objetivo diagnosticar a cultura organizacional dos hospitais, enfatizando as práticas e os valores organizacionais e a percepção dos colaboradores sobre a cultura organizacional. A metodologia utilizada na pesquisa foi de caráter descritivo e explicativo. A pesquisa ocorreu através da aplicação do Instrumento Brasileiro para a Avaliação da Cultura Organizacional IBACO, com 283 sujeitos distribuídos em três hospitais da rede privada de Natal/RN. As evidências encontradas pelo estudo foram analisadas através do software estatístico SPSS, com as técnicas multivariadas de análise fatorial, análise de aglomerados e análise discriminante. A partir dessas análises, foram obtidos cinco fatores distribuídos entre práticas e valores apresentados pelo IBACO, que foram: as práticas de recompensa e treinamento; integração externa e promoção do relacionamento interpessoal; e, os valores de satisfaão, bem-estar e cooperação dos empregados e profissionalismo competitivo. Os grupos encontrados na análise apresentaram divergências de opinião quanto às práticas e os valores utilizados nos hospitais. Concluiu-se, portanto, que o Hospital A apresentou uma cultura mais proativa e voltada mais para a satisfaão e bem-estar dos funcionários. Já os outros dois hospitais apresentaram culturas semelhantes, com limitações quanto à valorização do bem-estar e da cooperação entre os colaboradores, porém com uma boa prática do relacionamento interpessoal
