Limbal autograft transplantation in a dog with alkali-induced ulceration

Descreve-se um caso de um animal da espécie canina, fêmea, sem raça definida, de três meses de idade, com histórico de apatia, contato prévio com produto alcalino (hidróxido de sódio) e relutância em abrir o olho direito. Ao exame oftálmico, foram observados blefarospasmo, fotofobia, epífora, quemose discreta, hiperemia conjuntival, e edema corneal difuso com comprometimento do limbo. Foram realizados o teste da fluoresceína positivo e o Teste Lacrimal de Schirmer 32mm min-1. Com base nos achados, firmou-se o diagnóstico de úlcera por álcali e realizou-se transplante autógeno do limbo. No pós-operatório, observou-se vascularização corneal a partir do terceiro dia e sua intensificação, em número e calibre, nos dias subseqüentes. Também foram observadas mínimas áreas de transparência corneal. Os resultados obtidos permitem admitir que o transplante autógeno de limbo é procedimento factível para o manejo da terapia de úlceras de córnea por álcali.

Expansão canavieira e ocupação formal em empresas sucroalcooleiras do Centro-Sul do Brasil, entre 2007 e 2009

Considerando-se a região Centro-Sul do Brasil e com base nos dados do Ministério do Trabalho e Emprego e do Ministério da Agricultura, Pecuária e Abastecimento, comparou-se a evoluçãoda produção sucroalcooleira comonúmero e tipos de pessoas formalmente ocupadas em empresas do setor, de 2007 a 2009. Nas empresas dedicadas ao cultivo da cana-de-açúcar, o número de pessoas ocupadas caiu nesses três anos, enquanto aumentava nas empresas dedicadas à produção de açúcareetanol.Quantoàscategoriasdeocupação,constatou-seaumentononúmero de pessoas ocupadas em atividades industriais, administrativas, de apoio ou não sucroalcooleiras, enquanto diminuíam as pessoas ocupadas na agricultura. Neste caso, houve redução dos trabalhadores canavieiros não qualificados e crescimento dos trabalhadores da mecanização agrícola, fatos associados à intensificação da adoção da colheita mecânica de cana-de-açúcar. Não ocorreu mudança expressiva na sazonalidade de emprego dos trabalhadores canavieiros não qualificados, que permaneceu muito alta. O aumento mais intenso da produção do que do número de pessoas ocupadas refletiu em indicadores de produtividade, com crescimento da relação da produção de cana-de-açúcar, tanto com o total de pessoas ocupadas, quanto com o número de trabalhadores canavieiros não qualificados. Também foi constatada redução significativa na relação desse grupo de trabalhadores com a área colhida com cana-de-açúcar.

Universidade e educação ambiental

The society consists of the inter-relations between diverse symbolic fields of performance, where some agents if identify for values, habits and goals. The present thesis analyzed, taking for base the Theory of the Social Field of Pierre Bourdieu, the ambient field and the university, leaving of the principle that the university is one of the propitious places for the quarrel, study, knowledge elaboration, and that the ambient education is one of the ways of dissemination of knowledge and action in favor of the ambient question. It was looked to contextualize and to identify the main factors that configure the university while a social field, and to evidence the conflict and connector links with the ambientalism. It is perceived university as space of tensions, whose produced capital stock in the academic scope must be enough convincing in the direction of the social transformation, of the expansion of conscience, the critical matureness, and thus to appear as agent of social transformation. The joint between the diverse social fields, promoted for the university, will be able to contribute for knowledge formularization that can consist base for elaboration of politics and programs to answer to the problems of the society contemporary. It has the inter-relationship between the two fields, however, this relation still is fragile, needing that a continuity practical social that they make possible that the ambient question is part of the culture of the university. This will be able to give with the intensification of the actions and the inclusion of the ambient questions in the communication mechanisms and administrative management. To surpass discontinuities caused for changes of groups leading and for interests politician conjunctural are necessary that they create habitus, what passes for the institutionalization of practical and the constitution of a culture that the agents allow if to reorganize defending the interests of social transformation front to the economic interests, as much in the university how much in the ambient field

Trabalho e formação docente na rede municipal de ensino de natal

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

Programa de apoio a planos de reestruturação e expansão das Universidades Públicas Federais (REUNI): repercussões na UFRN

El presente trabajo tiene como objetivo analizar la implantación del Programa de Apoyo a Planes de Reestructuración y Expansión de las Universidades Federales (REUNI) así como su papel en la reconfiguración de la Universidade Federal do Rio Grande do Norte, resaltando sus repercusiones en la gestión y organización de la universidad. Para la realización del trabajo, entre los procedimientos técnicos, utilizamos la revisión de literatura, el análisis de documentos y las entrevistas semiestructuradas. La revisión bibliográfica ha permitido profundizar en conceptos importantes sobre la temática, priorizando los contenidos referentes a los conceptos de globalización y neoliberalismo; La reforma del Estado y sus repercusiones sobre las políticas de educación superior brasileña; directrices de documentos internacionales y nacionales que definieron la organización de este nivel de enseñanza. Los estudios indican, en relación a la expansión de la UFRN, que las metas pactadas del REUNI fueron atendidas casi en su totalidad. Sin embargo, cualitativamente, no se puede afirmar que el REUNI haya tenido un impacto positivo, pues además del incremento de plazas y de la creación de cursos nuevos, que en su mayoría fueron cursos nocturnos, ha habido un aumento sustancial en relación a la cantidad de alumnos por profesor, lo que demuestra que dicho incremento también se da por la racionalización de los recursos humanos y de la estructura físca existentes. Desde esta perspectiva, el REUNI originó varias modificaciones en la forma de gestionar los servicios en la UFRN, mereciendo especial atención la intensificación del proceso de transformaciones en la concepción de una gestión burocrática a una gestión desde la gerencia, resaltando la cultura instituída con el contrato de gestión. En ese sentido, la utilización de las metas y de los indicadores de desempeño pasa a adquirir cada vez más importancia como forma de acompañar y evaluar el cumplimiento de las acciones pactadas, pues de este cumplimiento depende la concesión de recursos financieros. Dentro de este contexto, el Programa se ha caracterizado por dar continuidad a las políticas de privatización para la expansión de la educación superior brasileña, provocando la inserción en las universidades públicas federales, de un modelo de organización fundamentado en el paradigma de la gerencia y la administración, que conlleva así, a la mercantilización de los bienes y servicios académicos

As condições do trabalho docente: um estudo em escolas da rede municipal de Currais Novos-RN (2009 a 2012)

This work, named Teaching conditions: a study in municipal schools of Currais Novos RN (2009 to 2012) aims to analyze the status of teaching in schools in the municipality of Currais Novos RN in the period ranging from 2009 - 2012, considering infrastructure, initial and continued training and intensification and casualization of teaching factors in the context of the 1990s educational reformations. It, also, assumes that teaching is a constitutive part of capitalist society, and has been reconfigured with based on the new requirements demanded by the labor market. In order to conduct this study the considered data included the survey research Teaching Work in Basic Education in Brazil (2009 to 2010) , held in seven Brazilian states being: Pará, Rio Grande do Norte, Minas Gerais, Goiás, Paraná, Santa Catarina and Espírito Santo. Specifically selected for deepening of the study, there were schools in the municipality of Currais Novos in which semi-structured interviews were performed with teachers of the said municipality. This research is constituted of a qualitative and quantitative approach whose survey instruments adopted were, namely: documental research, literature review, interviews and surveys. The obtained data analysis allows us to infer that the teaching work performed by teachers in the states which participated in the survey has been influenced the changes in the labor market and educational reformations and has been taking on characteristics such as flexibility, tendency to precariousness and intensification; and this trend is also present in schools that were surveyed in the municipality of Currais Novos. As pertaining to the teachers conditions in classroom, these signs are more evident, considering that they had their duties and responsibilities extended beyond the classroom environment. The data also show that in general working conditions of teachers in national, state and local levels are unprofitable and heterogeneous, increasingly deepening the gap between school units and education networks. Therefore, the implantation of public policies that enhance the teaching work and improve their working conditions in all dimensions that directly interfere in their work are crucial

Sensibilidade interoceptiva e respostas psicofisiológicas ao exercício submaximo

The complex human behavior related to exercise involves cognitive, physical and emotional processing. The recent theories about exercise s intensity regulation have highlighted the role played by psychophysics aspects in controlling exercise s intensity. In this regard, recent evidences have shown that there is variability in human capacity in perceiving interoceptives clues. Thus, subjects more sensitive show higher physiological arousal to physical and/or emotional stress, and sensations with higher intensity. In fact, studies have evidenced that interoceptive feedback modifies behavior in exercise with free load. However, exercise recommendations are based in a constant load standard. Therefore, we aimed to analyze the influence of interoceptive sensibility on psychophysics responses during dynamic exercise performed with constant load. Twenty-four adult males were allocated into two groups accordingly with their interoceptive sensibility: high sensibility (n=11) and low sensibility (13). They underwent to an incremental test (IT) and then randomly to two sections of moderate and severe exercise intensity for 20 minutes. Heart rate (HR), rating of perceived exertion (RPE), affective feelings (AF), alert state (AS), and percentage of associative thoughts were collect during exercise. A two-way ANOVA with repeated measures was used to assess differences between psychophysics responses. There were differences between group in RPE, AF, and AS in moderate intensity. There was no difference in any measure in severe intensity. We conclude that subjects with high interoceptive sensibility feel dynamic moderate exercise more intense than the subjecs with low interoceptive sensibility

Inovações tecnológicas na caprinocultura

O largo crescimento do setor de agronegócios no Brasil tem estimulado mudanças nos sistemas produtivos, tanto na intensificação, como na profissionalização da produção. Dessa forma, os produtores têm buscado estratégias para melhor atender aos desafios da atividade pecuária atual, dentre as quais se destacam as inovações tecnológicas que devem resultar em comprovado benefício à atividade, seja pelo aumento em produtividade, seja pela melhoria na qualidade dos produtos, seja pela conscientização do respeito ao meio ambiente. Assim como em outros segmentos do agronegócio brasileiro, na caprinocultura existe uma demanda crescente pela aplicação de inovações tecnológicas, uma vez que o sistema produtivo precisa ser mais competitivo para se manter no mercado. Dentre as inovações tecnológicas aplicadas na caprinocultura, foram abordadas as mais relevantes nas áreas de reprodução (desde métodos para indução de cio até a prática da transgenia), melhoramento genético (biogenética), sanidade (inovações no diagnóstico e prevenção de doenças de maior impacto na criação), nutrição (inovações nos sistemas de alimentação) e tratamento de dejetos (diminuição de contaminantes no ambiente). A utilização conjunta das inovações tecnológicas nos diferentes segmentos associados à cadeia produtiva caprina pode fazer com que ocorram melhorias nos rebanhos assim como nos produtos gerados.

Características fermentativas e químicas de silagens de capim-marandu produzidas com quatro pressões de compactação

Objetivou-se estudar silagens de capim-marandu (Brachiaria brizantha) produzidas com quatro pressões de compactação (100, 120, 140 e 160 kg MS.m-3) durante a ensilagem. A forrageira foi colhida com 60 dias de crescimento vegetativo (32% de MS). O delineamento experimental utilizado foi o inteiramente casualizado com quatro repetições. Os dados relativos à produção de gás foram analisados por meio do modelo de medidas repetidas no tempo. As silagens produzidas com menores pressões de compactação apresentaram maior intensidade de produção de gases. em todos os tratamentos, houve baixa produção de efluente, como conseqüência do alto teor de MS da forragem no momento do corte. Nas maiores pressões de compactação, houve maior preservação dos teores de MS das silagens. Os valores de pH das silagens mais bem compactadas foram reduzidos em comparação aos daquelas com menor compactação, indicando que a maior densidade promoveu melhor ambiente para as bactérias produtoras de ácido lático. Os teores de N-NH3 (% N total) das silagens não foram influenciados pelas pressões de compactação durante a ensilagem; os resultados foram próximos aos considerados satisfatórios para conservação de gramíneas tropicais. A maior intensificação na compactação promoveu decréscimo nos valores de NIDN, fração B3, FDN e FDA e aumento na recuperação de MS e na digestibilidade verdadeira in vitro da MS.

Algoritmo Q-learning como estratégia de exploração e/ou explotação para metaheurísticas GRASP e algoritmo genético

Techniques of optimization known as metaheuristics have achieved success in the resolution of many problems classified as NP-Hard. These methods use non deterministic approaches that reach very good solutions which, however, don t guarantee the determination of the global optimum. Beyond the inherent difficulties related to the complexity that characterizes the optimization problems, the metaheuristics still face the dilemma of xploration/exploitation, which consists of choosing between a greedy search and a wider exploration of the solution space. A way to guide such algorithms during the searching of better solutions is supplying them with more knowledge of the problem through the use of a intelligent agent, able to recognize promising regions and also identify when they should diversify the direction of the search. This way, this work proposes the use of Reinforcement Learning technique - Q-learning Algorithm - as exploration/exploitation strategy for the metaheuristics GRASP (Greedy Randomized Adaptive Search Procedure) and Genetic Algorithm. The GRASP metaheuristic uses Q-learning instead of the traditional greedy-random algorithm in the construction phase. This replacement has the purpose of improving the quality of the initial solutions that are used in the local search phase of the GRASP, and also provides for the metaheuristic an adaptive memory mechanism that allows the reuse of good previous decisions and also avoids the repetition of bad decisions. In the Genetic Algorithm, the Q-learning algorithm was used to generate an initial population of high fitness, and after a determined number of generations, where the rate of diversity of the population is less than a certain limit L, it also was applied to supply one of the parents to be used in the genetic crossover operator. Another significant change in the hybrid genetic algorithm is the proposal of a mutually interactive cooperation process between the genetic operators and the Q-learning algorithm. In this interactive/cooperative process, the Q-learning algorithm receives an additional update in the matrix of Q-values based on the current best solution of the Genetic Algorithm. The computational experiments presented in this thesis compares the results obtained with the implementation of traditional versions of GRASP metaheuristic and Genetic Algorithm, with those obtained using the proposed hybrid methods. Both algorithms had been applied successfully to the symmetrical Traveling Salesman Problem, which was modeled as a Markov decision process

Remoção biológica de nitrato em água de abastecimento humano utilizando o endocarpo de coco como fonte de carbono

The groundwater quality has been compromised as a result of the intensification of human activities over the years. Groundwater contamination by nitrate is one of the effects of this degradation, a socio-environmental problem that affects many regions of the world and particular the city of Natal (RN). Developing techniques for nitrate removal in water is intended to eliminate or reduce the concentration of this compound, and those that involve biological processes have produced economic and environmental advantages. This study proposes a technology for biological removal of nitrate in water supply for humans, using the endocarp s coconut as a carbon source and bacteria support. The experiments were performed in pilot scale anoxic, testing different areas of the substrate surface. Results showed high rates nitrate removal during the monitoring period, noting the occurrence of denitrification after the beginning of system operation. The best performance was achieved in the treatment system containing substrate surface area increased, indicating that the decrease in the endocarp size contributed to increased bacterial activity, improving the ability to remove nitrate. About the quality analyzed aspects of water, it was found that the proposed technology has the potential water use for human consumption

Uma sequência didática a partir da temática terremotos com ênfase em CTS

Throughout its history the population of the region of Mato Grande, which includes the city of João Câmara, in Rio Grande do Norte, was subject to earthquakes. These events are caused by a geological fault, known as fault Samambaia. In the 1980s there was an intensification of this phenomenon culminating in an earthquake 5.1 on the Richter scale in the early hours of November 30, 1986, causing researchers from Brazil and other countries to shift to the region to conduct research in Seismology. During this period there was a strong interaction between scientists and local people. With the aim of studying how people experienced that moment that marked the history of the city of João Câmara, from interviews with some individuals who witnessed the incident, is that this research was developed. Taking as a theoretical approach to Science, Technology and Society (STS), aimed to thus carry the theme in a systematic way to the classroom, promoting ways to help teachers with the scientific training and guidance to students in case of occurrence of earthquakes

Avaliação clínica e microbiológica da mucosa oral de crianças com leucemia linfoblástica aguda, submetidas à ação profilática do gluconato de clorexidina A 0,12%

Regarding the morbidity potential of oral complications in patients with leukemia, it evaluated the clínical and microbiologic changes of oral mucosal in children with LLA, with age range of O to 15 years old, undergone the chemotherapy antineoplastic and for the use prophylactic of chlorhexidine gluconate 0,12% during ten days, that was utilized in each chemotherapy treatment stage. The collect for rnicrobiological study was obtained preferentiality in intensification stage at the end prophylatic treatment. The study grouup had 20 children, where it observed clinically decrease in frequency of mucositis, with 8 cases (40%) only. In microbiological examination observed one reduced incidence of pathogenic microorganisms with Staphylococcus coagulase- negative (40%), Klebsiella pneumoniae (5%), Escherichia coZi enteropathogenic (15%), Stenotrophomonas maltophilia (5%) e Candida albicans (35%). The findings obtained in the present trial suggest that the use of chlorhexidine gluconate 0,12% can be responsible for incidence reduced of mucositis, but it wasn t possible to make correlation between isolated pathogenic microorganisms and mucositis development
