The authors conducted a cross-sectional short-term study using Lind's Moral Judgment Test (MJT) to compare the moral judgment competence (C-score) among students in the first and eighth semesters from a medical school in the Northeast region of Brazil. This study also evaluated the influence of such factors as age and gender on moral competence. A difference equal to or greater than 5.0 points (absolute effect-size) on the C-score was considered significant. A regression of moral judgment competence among the students in their eighth semester in relation to the students in the first semester (C-score: 20.5 and 26.2 points, respectively) was observed. In the analysis of the students' performances in terms of MJT dilemmas, the phenomenon of moral segmentation was observed in both semesters, and the students performed better on the worker's dilemma than on the doctor's dilemma. Among students in the same semester of study, older students had lower C-scores. When comparing performance by gender, there was no significant difference between men's and women's C-scores. The finding of regression or stagnation in moral competence among the medical students demands deep reflection by those who work with the political-pedagogical projects of medical schools and by the entire faculty, in order to seek strategies to reverse this condition.

O gênero Astronium, pertencente à família Anacardiaceae, é composto por cerca de 35 espécies, sendo típico das regiões norte e nordeste do Brasil. De acordo com a literatura, apenas a espécie Astronium urundeuva foi investigada sob o ponto de vista farmacológico, sendo detectada atividades antiulcerogênica , antiinflamatória e efeitos no trânsito gastrintestinal . Nas espécies A. graveolens e A. fraxinifolium foram avaliados somente os óleos essenciais, sendo que em A. graveolens um desses compostos voláteis mostrou atividade repelente a insetos. Desta forma, percebe-se que a investigação desse importante gênero vegetal ainda é incipiente. Estudos preliminares com o extrato em acetato de etila das folhas de A. graveolens mostraram grande concentração de compostos fenólicos, como derivados de ácido gálico e flavonoides, os quais estão descritos na literatura em geral como substâncias antioxidantes em potencial. As propriedades antioxidantes de diversas substâncias são alvo de interesse nos dias de hoje principalmente por estarem relacionadas à terapêutica de doenças degenerativas. Com o objetivo de dar continuidade aos estudos das espécies citadas, foram utilizadas neste trabalho técnicas de cromatografia como análise por cromatografia líquida de alta eficiência para o estudo do perfil químico de Astronium graveolens, separação e identificação de metabólitos secundários. Baseado na literatura e na comparação com padrões, os espectros de ultravioleta observados, indicaram que os extratos em acetato de etila da espécie em estudo são compostos por substâncias derivadas do ácido gálico, derivadas do ácido cafeoilquínico e também por flavonóides. A substância Ag1 foi identificada a partir de experimentos de comparação por CLAE usando banco de padrões, após verificação de similaridade entre tempo de retenção e máximo de absorção...

Atualmente o encalhe de filhotes órfãos representa uma das principais ameaças à conservação do peixe-boi marinho (Trichechus manatus manatus) no litoral nordeste do Brasil. O Projeto Peixe-boi resgata os filhotes encalhados, reabilita em cativeiro e reintroduz estes animais em áreas de ocorrência histórica e em locais onde a população está em declínio. Estudos sobre comportamento animal fornecem uma importante ferramenta para avaliação dos Programas de Reintrodução. Os trabalhos existentes sobre comportamento de peixes-boi marinhos em vida livre sujeitos a interações antrópicas restringem-se a animais nativos na Flórida. No Brasil, há estudos etológicos apenas com espécimes em cativeiro ou recinto em ambiente natural. O objetivo do trabalho foi verificar possíveis alterações comportamentais de peixes-boi reintroduzidos, ou seja, que passaram parte da vida em cativeiro e foram soltos em ambiente natural, em função de interações antrópicas. No período de Fevereiro a Julho de 2010, com o auxílio da radio-telemetria, uma fêmea e dois machos (8 anos de idade) foram observados diariamente, em períodos alternados, com a metodologia do “animal focal”. Para o monitoramento, utilizou-se bicicleta, caiaque e, em locais de difícil acesso, o mesmo foi feito a pé. Totalizou-se 114 horas de observação para Arani e 167 horas para Potiguar. As observações da fêmea Aira ficaram comprometidas em função da perda do equipamento de radio-telemetria. A análise dos dados mostrou uma alta freqüência de comportamentos de interação (mais de 50%) em relação aos demais comportamentos de função vital para os dois machos. Dessas interações, as com animais de mesma espécie e objeto atingiram elevadas freqüências. Verificou-se ainda que a categoria afiliativa foi predominante nas interações entre peixes-bois...

The lesbian and gay movement has organized itself in Brazil with the goal of creating and making its sexual identity stronger, as well as fighting for its rights and against any homophobic act. This paper analyses the homosexual movement and its relation to building its own identity, as a fighting force. We emphasize the relevance of the manifestation events, such as the LGBT pride parade and, in Bauru, the diversity parade, events that not only provide visibility to the topic, with the presence of the media, but also, represent the voice of these people who search for their citizenship rights.

The sugar cane plantation expands its borders each year, throughout the national territory. Thus, increases the amount of biomass that will to be exploited by man in sugar and alcohol produce and also by other organisms, which will have food in abundance. The growth of mechanized harvesting, with the consequent decrease in burning of straw and the expansion of the sucroalcooleiro sector are causing changes into entomofauna in certain areas or regions of sugar cane plantation. One of the new threats to the sugar cane plantations in southcentral region, causing uncertainty and concern to farmers, is the giant worm, Telchin licus, known in Brazil since 1927, in the Northeast of Brazil, is considered a major pest of cane sugar. In 2007 it was first recorded in the state of São Paulo, which accounts for 60% of the country's crops. Whereas until then there is not much information about their management and control, the aim of this review is to gather information on the basis for its control within the context of Integrated Pest Management of cane sugar.

The Youth and Adult Education is a reality that still stands on the school benches of Brazil. Elderly people historically get more integration in the world when appropriate to the written code. One of the issues that touch this insertion is the right to vote and, more than that, the awareness of the vote of young and adult illiterate or poorly literate. Thus, this project aims to raise throug the point of view of this student how he see himself as voter and what is their role in the democratic consolidation of this act, even if he is in the condition of illiterate or poorly literate. Therefore, a qualitative approach to research will be conducted, in which individual audio recorded interviews will be held, later transcribed and the data will be analyzed in the light of the studied literature, based on the writings of Paulo Freire. Will participate as subjects Teachers of EJA and of study the students enrolled in the Education of Young Adults rooms on the city of Bauru. The results shown in interviews with the teachers confirmed the investigation of expectations in the study of Paulo Freire which has literacy training as part of the citizenship, the results allowed the construction of the profile of a group of students. We also concluded that it was possible to deconstruct the myth of non-political consciousness of the illiterate and the presence of dialogue in pedagogical practice enabling awareness of Educating

As opalas laranjas de Buriti dos Montes (Piauí, nordeste do Brasil) têm propriedades gemológicas que favorecem seu uso como jóias; essas características incluem as cores, transparência, dureza e estabilidade relativamente elevadas. O exótico conteúdo de inclusões sólidas proporciona maior beleza às opalas da região. Essas opalas foram originadas por processos hidrotermais e são encontradas, principalmente, em vênulas e veios nos arenitos do Grupo Serra Grande, seccionados por soleiras e diques de diabásio da Formação Sardinha. Inclusões sólidas, tais como bolhas, agregados botrioidais, dendritos e nódulos, entre outras, consistem, principalmente, de caulinita, hematita/goethita e quartzo e influenciam a composição química das opalas. O zoneamento intenso dos cristais de quartzo e os elevados valores de Ba e Fe sugerem que os depósitos de opala foram formados em ambiente hidrotermal. Os diques de diabásio teriam sido responsáveis pelo aquecimento dos fluidos hidrotermais. Os arenitos, ricos em soluções aquosas, também teriam contribuído com a sílica disponível para a saturação dessas soluções e as fraturas permitiram a migração e aprisionamento dos fluidos hidrotermais, resultando nos veios mineralizados.

Environmental conditions favor the predominance of dense populations of cyanobacteria in reservoirs in northeastern Brazil. The aim of this study was to understand cyanobacterial population dynamics in the rainy and dry seasons at two depths in the Arcoverde reservoir. Microalgae and cyanobacteria samples were collected during 24 hours with intervals of 4 hours (nycthemeral) at sub-surface and 10 m using a van Dorn bottle and a determined biomass. Physical and chemical variables were obtained and the data were analyzed using the principal component analysis (PCA). No nycthemeral variations in the taxonomic composition or distribution of the populations of cyanobacteria were found between the different times of day in either the rainy or dry season. In both seasons, the greatest biomass of the phytoplankton community was made up of cyanobacteria at two depths and all times of the day. Cylindrospermopsis raciborskii (Woloszynska) Seenayya et Subba Raju was dominant at all times of the day on both the surface and at the bottom. In the rainy season, the differences in cyanobacterial biomass between the surface and bottom were less significant than in the dry season. The differences in cyanobacterial biomass between surface and bottom were less pronounced than those found in the dry season. We concluded that a) physical variables better explain the alterations of species in the phytoplankton community in an environment dominated by cyanobacteria throughout the year; b) seasonal climatic factors associated to periods of stratification and de-stratification are important for alterations in the community and variations in biomass and, c) the turbidity caused by rainfall favored the emergence and establishment of other cyanobacteria, especially Planktothrix agardhii (Gomont) Anagnostidis & Komarek.

Biological aspects of sailfin dory, Zenopsis conchifer, were studied from 839 individuals obtained from deep-sea commercial bottom trawling off southern Brazil at depths up to 526 m in 2002 and 2003. Samples included fish from 101 mm Lt and 15 g up to 640 mm Lt and 2,9 g. The sex-ratio was 50% at 150 mm Lt and between 300-350 mm Lt, with females outnumbering males in the remaining size classes. Reproductive activity seems to peak between July and August ( austral winter). Size at attainment of 50% maturity (Lt(50)) was 311 mm Lt in females. The mean length and maturity of the specimens increased with depth, suggesting that larger fish concentrate in deeper waters.
