O objetivo do presente trabalho é o entendimento da dinâmica do mercado dos alimentos orgânicos no Brasil, sua cadeia produtiva e as relações comerciais estabelecidas especificamente com a União Européia. Apesar do segmento orgânico crescer a altas taxas ao redor do mundo, ainda é uma temática (promissora) pouco estudada nacionalmente, o que dificulta o desenvolvimento de processos que poderiam diminuir os entraves enfrentados pelos produtores orgânicos. Inicialmente situando o leitor sobre as origens do cultivo orgânico e apresentando o panorama mundial atual, o trabalho entra no cenário nacional discutindo o perfil do produtor, o paralelo entre insumos tradicionais e aqueles específicos para a produção orgânica, além das dificuldades de financiamento em âmbito nacional. Em seguida, discute-se questões relativas à comercialização: qual o perfil do produtor e quais os sistemas de distribuição da produção orgânica nacional e internacional; o porquê dos preços de produtos orgânicos exibirem margens de lucro tão altas; de onde vem a necessidade de certificar a produção, quais as principais certificadoras e seus métodos de atuação. A partir deste embasamento, pode-se trabalhar, então, as relações comerciais estabelecidas entre o Brasil e a União Européia, bloco de destino de mais de 70% da produção orgânica nacional; trata-se, então, das leis e das certificações necessárias para efetuar as exportações; dos principais produtos exportados dentro do segmento orgânico e das 19 empresas responsáveis por essas exportações. Percebe-se, por fim, que um dos principais entraves ao desenvolvimento do segmento ainda é a falta de investimentos em P&D, pois a carência de dados sistematizados e pesquisas em geral acabam por desestimular tanto produtores quanto consumidores em busca de informações sobre esse mercado pouco evidenciado nacionalmente

The use of stable isotopes in Brazil is being improved, mainly through research conducted at main universities in the country. Some applications in health allow to studying, for example, processes involving synthesis and protein degradation, energy expenditure, body composition, kinetics of vitamins, mineral absorption and diagnose diseases related to Helicobacter pylori. The big motivation is to encourage the growth of investments in health in the few centers that have mass spectrometers in Brazil, as the technique is harmless to humans, in other words, no has problems to use it like when you use radioactive isotopes

O presente relatório científico tem como proposta apresentar o processo de elaboração do livro-reportagem “As vozes que ninguém quer ouvir – Um retrato das presas estrangeiras no Brasil”, fruto do trabalho de conclusão de curso de Ana Navarrete e Juliana Santos. O livro parte da temática de mulheres vindas de outros países que são presas e cumprem pena no Brasil, para apresentar seus perfis, os motivos que as levaram ao cárcere, a vida dentro do presídio, as dificuldades jurídicas por questões de gênero e nacionalidade e a vida pós-prisão. Para isso, foram utilizados três recursos que podem compor um livro-reportagem: a grande reportagem, o perfil literário e o ensaio fotográfico jornalístico. No decorrer deste documento será apresentada a contextualização do tema, a base teórica jornalística, os objetivos, a justificativa e pretensões do trabalho, as dificuldades no processo de produção do livro e as conclusões finais das autoras. O trabalho (desde a confecção do produto, até as pesquisas e a interpretação das alunas sobre o tema) foi guiado sob a ótica dos direitos humanos. O objetivo foi dar voz a essas mulheres e levar até os leitores suas histórias, de maneira a conscientizar e incentivar debates e mudanças na situação das estrangeiras presas no Brasil

The freshwater phytoplankton, responsible for a significant part of primary production in rivers and lakes, is of great importance for matter and energy available to other trophic levels of structuring aquatic food chains. In recent decades, the construction of dams, especially for the generation of electricity, produced changes not only in physical and chemical characteristics of rivers, but also in biocoenosis of these ecosystems. Thus, research is needed to expand the basic knowledge about these environments and subsidize actions appropriate conservation and management. Considering that lotic environments are relatively little studied, and the river-reservoir interaction, the work aims to analyze the limnological conditions and assemblies phytoplankton along the gradient established by the Itaipu reservoir and downstream stretch of the Paraná River. During two periods of the year, winter and summer, we analyzed nine sampling stations: one in lentic environment (the dam), six on the Parana River (each 5 km), at the mouth of a river Monday and another at the mouth of the Iguazu river. The phytoplankton community was composed of 315 taxa, with the class Bacillariophyceae most specious. At every point the richness was higher in summer and with a longitudinal trend in the increasing points after falling after the dam and the contribution of the tributaries. The number of taxa common to the three rivers was low in both study periods. The higher taxa can be explained by the variety of environments sampled, different residence times of water and nutrient concentrations, whereas the rivers Iguazu and Monday suffer high human influence. The greater abundance of organisms in the dam, in both periods, it should be the class Cryptophyceae contributing over 75% of total phytoplankton in point. In cluster analysis (composition and abundance)...(Complete abstract click electronic access below)

Tuberculosis and brucellosis are important diseases in national scenario, as they affect national cattle and can be transmitted to human, as they are zoonosis. The transmission risk increases mostly for those who have strict contact with animals, as is this case of slaughterhouse workers. This paper presents a bibliographic review of data referent to both diseases occurring in bovine slaughterhouse workers in Brazil, characterizing as occupational zoonosis diseases. We still have few data available of this subject, what raise difficulties to know the real incidence of both diseases in national cattle and in people who work in contact with animals, and most of the time are not instructed to the risk that they are exposed and how to prevent it. It’s important to know which is the situation of both diseases so that prevention and even eradication measures can be taken, as we know the Veterinary has an essential function in this matter, protecting animal health as much as protecting national public health

This article chiefly aims at discussing issues concerning reflective teacher education for and in virtual environments for language learning. Given the need for research on reflective practice in new virtual environments, we present the experience of pedagogical supervision through mediation in the virtual context for collaborative learning in teletandem. Some research results in this context, such as in Salomão (2008), Kfouri-Kaneoya (2008), Cândido (2010) and Silva (2010), show how favorable and conducive to the development of reflective pre-service teacher education it seems to be, as it emphasizes the co-construction of knowledge in a dynamic relationship between theory and practice.

Radiopharmaceuticals are substances marked with radionuclides that can be used for detection and treatment of cancer, infections and inflammatory diseases. They emit several types of radiation through different decay routes, each radioisotope with its specific properties and uses. They can usually be produced from several different materials, by bombardment with particle beams in a nuclear research reactor or cyclotron, depending on their characteristics. Brazil has four public institutions which produce - or import - and distribute radiopharmaceuticals to hospitals and clinics throughout its territory. The largest such institution, Ipen, distributes 97% of radiopharmaceuticals used in the country. Some radiopharmaceuticals decay very quickly, meaning they must be produced and quickly administered to the patient in the same location, presenting a logistical challenge. Nuclear medicine in Brazil is a promising field and has been steadily growing, although rigid laws and a lack of qualified work force hinder Research and Development efforts for new radiopharmaceuticals. The construction of a new nuclear research reactor, in 2016, should generate self-sufficiency and economy in radiopharmaceutical production and avoid a future crisis in the supply of technetium-99m, the most important radioisotope, used in over 80% of procedures with radiopharmaceuticals.

As reflexões e iniciativas brasileiras e africanas sobre acordos de cooperação mútua no plano científico, artístico e cultural vem crescendo nesta primeira década do século XXI visando uma integração e a constituição de mecanismo de cooperação técnico-científico a partir das história comuns que envolvem os escravismos, o tráfico, a diáspora africana, as independências e nossa identidade cultural construída no Atlântico. As universidades brasileiras através de seus centros e núcleos de pesquisas vinculados aos estudos sobre as populações afro-brasileiras e as sociedades africanas tem caminhado nesta direção de modo paulatino, mas flagrante.

The present study, theoretical, aims to talk about educational policies in Brazil, aiming to unveil what they say these policies, the legitimacy and visibility that give coverage of sexuality in schools. Both sexuality and gender relations have gained attention in a Brazilian educational research in the mid-90th century. These policies have been the National Curricular Parameters (PCN). They present the cross-cutting themes: ethics, health, environment, cultural diversity and sexual orientation, which should be integrated into conventional areas of the school said. Another document of this same decade of education is the National Education Plan (PNE), however this encompasses so hidden sexuality and gender relations. In fact, both the new Law of Directives and Bases (LDB), the PNE in these subjects are veiled. An interesting initiative is happening in Brazil is the project Gender and Sexual Diversity (GDE) for the training of professionals in education issues of gender, sexuality and sexual orientation and ethnic-racial relations, is entering the national perspective of implementation public policy of equality and respect for diversity. However, much remains to be done thinking about the effectiveness of public policies that are effective with respect to space and visibility for the treatment of sexuality. We must also articulate the integration of these themes in these policies, strategies to raise awareness of education professionals in order to secure that they are actually implemented.

The main objective of this paper is to answer the following question: how can we draw a parallel, during the analysis of the data, between children who are at different moments in the language acquisition process or who belong to different populations (children that are monolingual, bilingual, with language disorders, etc.)? In order to answer this question, we are discussing the advantages and limitations of adopting a measure like MLU, from English Mean Length of Utterance, or EME as it was named in Brazil, proposed by Roger Brown (1973). We intend to verify the effective contribution of these measures to the studies in the area and propose an adaptation in the studies that use a qualitative approach. Firstly, we recall the study of the criteria proposed by Brown (1973), Scliar-Cabral (1976), Parker & Brorson (2005), Parisse & Le Normand (2006), and Araújo (2007), and by scholars of Brazilian Portuguese morphology, like Câmara Jr (2009), Monteiro (2002), and Kehdi (1990), among others. Secondly, from a dialogic-discursive point of view (BAKHTIN, 2006; BAKHTIN/ VOLOSHINOV, 1992, 1981), we provide as an example the research on the plural in the language acquisition process (HILÁRIO, 2010, 2011b, 2012). The reflections made indicate that EME may be a useful measure for the researches on language acquisition. Nevertheless, adaptations should be done and its inherent problems should be taken into account, especially if other factors are considered – like the age, the number of types/occurrences, the maximum limit of items per utterance etc. – although it is not the only parameter of analysis. Considering that EME may vary according to the conditions of production and may not reflect the qualitative changes in the children’s discourse, other factors should be analyzed, like the context of the discourse, the participants involved etc.
