On the beginnings of the XXI century the brazilian universities was claimed by the Government and by the society to rebuild your ways of selecting students. Many questions are behind this theme, that goes since the concernings of the higher education institutions about select and graduate students, and now also students from disadvantaged sectors of the society; but also about personal issues, like concerns of the everyday of millions of youngs that integrates the brazilian society and that need to decide about your professional future after the finish of the Basic Education. The present thesis has as objective analyse the processes of the transition between the Basic Education and Higher Education on the point of view of students that achieved a place on the public university. This study was accomplished on the Federal University of Rio Grande do Norte [UFRN on the original language], that implemented an Access and Social Inclusion Policy (PAIS [on the original language]) on the year of 2003, and since than a series of social actions had been developed. Among the main, we highlight the Inclusion Score action, an adicional score [on the entrance selection exam] for graduated students from public schools, which considers social and economic criteria and the academic development of these candidates on your Basic Education. Through quizzes and interviews with the graduated university students from public network, we could know the social, economic and academic profile of the students that entered on the UFRN by the time of the development of your PAIS, your schools and university trajectories, revealing some of the dilemmas, strategies, difficulties and personal cost of those that try to remain on the educational system besides the adversity conditions of schooling. For the theory foundation, we use authors like Bourdieu (1992, 1996, 2003); Coulon (1993, 2008); Ramalho (2004, 2007, 2008, 2010); Ramalho, et al (2011); Charlot (2001, 2003, 2005); Zago (2011); Nogueira, Romanelli e Zago (2011), among others, that contributed for a better analysis and understanding of thought and actions of the students in your own formative trajectories. Although we know that the educational inequalities are many, we found that the UFRN policy brought and is bringing many significant results, on the perspective of contribute with the increase of access for graduated students from the public network, and with the inclusion of these on the university

The Hepatus pudibundus (Herbst, 1785) juvenile development was studied in laboratory, under the morphological and systematical stand points. The eight early juvenile stages were obtained from larvae hatched from eggs of two ovigerous females, collected at the northern coast of the State of São Paulo, Brazil. The experiments were carried out in a climatically controlled room at 25 ± 1°C, and steady saltness of 34 . The youngs were maintened individually and food consisted of Artemia sp. nauplii and fragments of fish muscle.The first juvenile stage were particulary drawn and described. For the remaining juvenile stages the most representative frameworks were picked out, which allowed the characterization of the first eight stages. According to juvenile morphology studies, it was noted that secondary sexual characters differentation begins from the third stage.

Brains of Wistar male rats (newborns, youngs and adults) submitted to protein-calorie deprivation for different periods (27, 33 and 60 days) were studied histologically and biochemically (protein and lipids contents). Lower levels of lipid, particularly among young rats, were observed in all groups. The protein levels were also significantly lower in the newborns, only slightly diminished in the youngs and not altered in the adults. On the other hand the histological study made in all groups did not show any qualitative modifications. The authors concluded that the protein-calorie deprivation affects the brain composition markedly in the earlier periods of life when the developing rate is greater. This could result in irreversible brain damage.

Habitat split is a major force behind the worldwide decline of amphibian populations, causing community change in richness and species composition. In fragmented landscapes, natural remnants, the terrestrial habitat of the adults, are frequently separated from streams, the aquatic habitat of the larvae. An important question is how this landscape configuration affects population levels and if it can drive species to extinction locally. Here, we put forward the first theoretical model on habitat split which is particularly concerned on how split distance - the distance between the two required habitats - affects population size and persistence in isolated fragments. Our diffusive model shows that habitat split alone is able to generate extinction thresholds. Fragments occurring between the aquatic habitat and a given critical split distance are expected to hold viable populations, while fragments located farther away are expected to be unoccupied. Species with higher reproductive success and higher diffusion rate of post-metamorphic youngs are expected to have farther critical split distances. Furthermore, the model indicates that negative effects of habitat split are poorly compensated by positive effects of fragment size. The habitat split model improves our understanding about spatially structured populations and has relevant implications for landscape design for conservation. It puts on a firm theoretical basis the relation between habitat split and the decline of amphibian populations. © 2013 Fonseca et al.

O presente estudo teve o propósito de determinar as características reprodutivas básicas de pacas criadas em cativeiro, tais como: duração do ciclo estral, duração do período gestacional, intervalo do parto ao primeiro cio pós-parto, duração do intervalo entre partos, além do número de produtos por parto e da proporção sexual. Foram utilizados treze animais, todos criados em cativeiro no Biotério da Universidade Federal do Pará sendo que os dados foram obtidos através de técnicas colpocitológicas, exceto aqueles relacionados à determinação do produto por parto e à proporção sexual, os quais foram observados diretamente após o parto. O período médio encontrado para o ciclo estral foi de 32,5 ± 3,69 (n = 20) dias sendo classificado em quatro fases: proestro, estro, metaestro e diestro. Estes resultados indicam que esta espécie tem poliestxo com reprodução contínua. Quanto ao período gestacional, dois resultados foram obtidos: a) 147,5 ± 2,83 (n = 2) dias para fêmeas cujo último cio foi confirmado com a presença de espermatozóides na lâmina e b) 146,7 ± 6,43 (n = 3) dias para fêmeas que tiveram a confirmação do início da gestação apenas pelas características clínicas do último cio antes do parto, confirmado através da caracterização da lâmina. Os filhotes apresentaram, ao nascer, olhos abertos, corpo completamente coberto de pêlos, movimentos ativos e capacidade de comer alimentos sólidos dentro de dois dias. O peso médio foi de 605,9 ± 87,47 g (n = 12) para as fêmeas e de 736,7 ± 108,41 g (n = 14) para os machos. Dos 38 nascimentos ocorridos no Biotério, nenhum foi gemelar, embora a paca seja capaz de produzir gêmeos. O intervalo entre partos foi de 187,3 ± 8,48 (n = 15) dias e dentro de 35,6 ± 5,22 (n = 5) dias ocorreu o primeiro cio pós-parto. Estes resultados podem servir de base para futuros trabalhos que tenham como objetivo o estudo de parâmetros reprodutivos de animais silvestres através da biotecnologia. Além disso, criatórios bem manejados de pacas podem tornar-se, no futuro, fonte de alimentação com qualidade e fonte de renda acarretando, desta maneira, a garantia da preservação da espécie.

Apresentamos uma pesquisa fundamentada na obra A importância do ato de ler e outros textos de Paulo Freire. Numa sala de aula com 16 alunos jovens e adultos, em sua maioria migrantes de outros Estados do Brasil, a leitura da arte, em forma de imagens, músicas e poesias, instigou-os a ler também suas histórias de vida e as situações de opressão que vivenciaram. E reconhecendo suas situações de dominação e superando a visão ingênua e conformista, enquanto sujeitos do processo educativo e da própria história, foi-lhes possível adquirir uma visão mais crítica e superar as próprias limitações.

O presente artigo pretende investigar como os profissionais que atuam junto a jovens infratores, percebem as causas que os levam a essa situação, contrapondo essas percepções aos estudos bibliográficos. Para tanto, foram realizadas entrevistas com uma Psicóloga e uma Assistente Social que atuam no escritório da FEBEM no município de Rio Claro.
