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

This paper presents a study on the labeling Procel Build, an action plan for energy efficiency in buildings which aims to build the foundations necessary to rationalize energy consumption in buildings in Brazil (PROCEL, 2009a, p. 5), ie Procel builds aims to ensure the construction of the building that has a low energy expenditure, but still provide a comfortable environment. In this research, it is also shown how the labels are obtained, which may be general or partial. The reader will find further explanation of the three aspects of a building, and they Envelopment, Lighting system and Air Conditioning System Finally, we present the advantages and challenges of system builds procel, showing the need for greater investment and disclosure of elements that contribute to the implementation of sustainable buildings in Brazil

With the growing market for advertising geared towards the infant public, inserting since small children in the capitalist world with his powers of persuasion, raises concerns in knowing what are the subjective messages that advertisements are transmitting to them. The television since its appearance has the power to normalize and regulate society imposing the mode of life and how they should act, think and dress. Starting this strand to analyze the influence of television on society, this work explores the current advertisements for children to check whether messages meets reality, or have an ideological conception of the world, focusing, besides consumerism, the relationship about the issue of gender of being male and being female

This work aims to analyze the toughness of a welded joint in the presence of a crack through the analysis of maximum tension the material can withstand the presence of this type of defect, since a discontinuity is likely to occur in this type of joint and its detection and its design is simple, using non-destructive testing techniques. The study will be conducted through the CTOD test - Crack-Tip Opening Displacement, with type specimens SE (B) - Single Edge Bend taken from a weld in the L-C position in relation to the length (longitudinal axis) of a test tube. The main idea is to simulate the welding conditions for the manufacture of industrial pipes, made in boiler shops (pipe-shop) within petrochemical plants. These pipes are often subject to operation with flammable and toxic subjected to high pressures and temperatures, where one can break the line can cause irreparable damage to the plant, the environment and the health of surrounding communities. With this study we evaluate whether the weld metal has the same properties as fracture toughness of the base material. This study shows the importance of using a qualified welding procedure for performing quality welds while maintaining the properties of the fracture toughness of the base metal. It was found from the results of tests using a welding procedure described for carrying out welding ensures mechanical properties very close to the base metal, which in terms of design is great, since one can ensure that the weld will the same characteristics of the base metal specified for the assembly of the pipe

The welding process in industrial piping is still the most effective way to ensure the durability and quality of the wide range of industrial process, although because of the high demand for energy and quality of the produced products, the piping has been constantly tested for high pressure applications and still high temperature. The welding method analyzed is the TIG (Tungsten Inert Gas) welding or GTAW (Gas-Shielded Tungsten Arc Welding), which ones have as principal feature the utilization of a not consumable tungsten electrode in the torch extremity , in this process is necessary a protective atmosphere of inert gas. The welding TIG advantage is the obtaining of a welded seam clean and with quality for not has slag after the welding. This work has as objective show the variability in the carbon steel piping welding parameters and by the tests in four proof bodies will be shown the influence of the variation of the welding methods in a welded seam. The tests will vary since the piece to be welded preparation, till penetrating liquid tests, welding macrography, welding x-ray and traction tests. Even been a clean and with quality welding is necessary a final inspection in the seam welded looking for defects almost inevitable resulted of the welded process, the obtained results have the objective of indicate and minimize the defects to ensure quality and durability of the welded seam

Lately, the acceptability of fermented dairy beverages has been increased, due to the nutritional benefits, the practical consumption and the low cost of product for the manufacturers, and consequently for final market price to the consumers. During the manufacturing process, these products can be susceptible to microbiological contamination. The present study investigated the contaminant microbiota in fermented dairy beverages produced by small- and medium-sized companies, by means of analyses on moulds and yeasts counting, determination of the Most Probable Number (MPN) of total and thermo tolerant coliforms, Escherichia coli and Salmonella spp. detection, and determination of pH value. In spite of the absence of Salmonella spp., a high counts of yeasts and moulds were found, and E. coli was detected in five samples (16.67 %); and the sample were classified as “products in poor sanitary conditions”, because they showed thermo-tolerant coliforms counting higher than the standard established by the legislation in force. Therefore, quality programs such as Good Manufacturing Practices (GMP) and Hazard Analysis and Critical Control Points (HACCP) should be employed to prevent any contamination risk, in order to provide safe products to consumers.

Com elevadas taxas de crescimento e participação cada vez maior no comércio mundial, a China intensifica suas relações com o Brasil e com a América do Sul, na qual apresenta-se como exportadora de manufaturados e importadora de commodities. Os efeitos desta relação devem ser estudados com cautela, pois apesar dos ganhos de curto prazo, geram perigosos impactos a médio e longo prazo. No Brasil, a presença chinesa é uma ameaça imediata ao setor industrial tanto no mercado interno, quanto externo

Many structures and mechanical equipment requires a union member, and the screw is one of the most used, the cost is low, it is versatile and easy to find on the market. The resulting pre-load assembly torque associated with the cyclical external load has great influence, so it will be studied carefully. This study analyzed some of these factors, as the format of nuts, and the washer material when they are incompatible with the bolt material can cause a reduction in life of the joint fatigue
