The DGT technique has been used to determine and better understand the dynamics and bioavailability of metals in the sea near to marine outfalls. In this work, the DGT was assessed for the determination of Cd, Pb, Cu, Zn and Ni in marine water samples from Potiguar Basin in its conventional aspect (binding agent, Chelex-100 and diffusive agent: Diffusive polyacrylamide gel (D) and restrictive (R)) and determination of Pb and Cd through its alternative aspect (binding agent: Saccharomyces cerevisiae immobilized in agarose gels and diffusive agent: 3MM Chromatography Paper). The deployment curves for long periods of immersion in the sample, showed a good linear correlation for the conventional aspect to Zn (D: R²=0.9586, R: R²=0.9444), Ni (D: R²=0.9789, R: R²=0.9286) and Cu (D: R²=0.764, R: R²=0.8143), and alternative to Pb (R²=0.9228) and Cd (R²=0.9673). The results of the organic and inorganic composition analysis in conventional aspect, showed that for every element there is no significant fraction of organic compounds in the sample. In addition, considering the alternative aspect, the comparison of obtained and expected masses suggests that some of the Pb is not labile and that the main retention mechanism of Pb for S. Cerevisiae occurs through ion exchange

Electrical installations in industries involving high currents and voltages considered. On the other side is the common appearance of electrical failures, caused by human error, defects in electrical equipment or electrical installation aging itself. These failures are varied, those with the highest rate of occurrence and cause much damage to electrical installations, are overcurrent and overvoltage. Therefore there is a need to project a system that can detect and minimize possible effects caused by faults in electrical installations industries. Protection systems in electric industries emerge as an alternative to control especially voltage and current magnitudes. Engineered based on the functions of the relays, protection systems are an indispensable tool for any industrial substation. But the project of such systems becomes increasingly more complex, due to technological development. Electrical equipment not develop at the same speed that the protective devices (relays), making it indispensable knowledge of integration of technologies

O objetivo deste artigo é fundamentar teoricamente as políticas industriais, caracterizando as razões da preferência por um referencial teórico não equilibrista e nãomaximizador. Procura-se também definir de maneira eficaz estas políticas, destacando seus resultados positivos em termos de alguns parâmetros. Este artigo será publicado em duas partes. Nesta edição define-se política industrial, analisando-se também as razões da despreocupação com uma fundamentação mais rigorosa das políticas industriais. Em seguida, apresenta-se sucintamente uma teoria capaz de embasar estas políticas, ao mesmo tempo em que se analisa se tais teorias são importantes (ou não), em termos empíricos. No quarto item, que será publicado na próxima edição deste Boletim, discute-se a possível utilidade da política industrial, enfatizando falhas de mercado, bens públicos, mercados não-competitivos, externalidades e desenvolvimento tecnológico.

O objetivo deste artigo é, essencialmente, fundamentar teoricamente as políticas industriais, sobretudo mostrando as razões da preferência por um referencial teórico não equilibrista e não-maximizador. Busca-se também definir de maneira eficaz estas políticas, destacando seus resultados positivos - pelo menos potencialmente - em termos de alguns parâmetros (produção, eficiência, produtividade, renda, bem-estar, etc.). Para isso define-se política industrial, analisando-se também as razões da despreocupação com uma fundamentação mais rigorosa das políticas industriais. Em seguida, apresenta-se sucintamente se uma teoria capaz de embasar estas políticas, ao mesmo tempo em que se analisa se tais teorias são importantes (ou não), em termos empíricos. Nesta segunda parte discute-se a possível utilidade da política industrial, enfatizando falhas de mercado, bens públicos, mercados não-competitivos, externalidades e desenvolvimento tecnológico.

From a theoretical foundation favorable to industrial policies, this paper intends to show the main policies followed by Ireland since the 1950s, with a special emphasis on those directed to Science, Technology and Innovation (S,T&I), FDI and high tech sectors, like software and biotechnology. We compare these policies with those used in Brazil, in a similar period, in order to have some hints for virtual transformations of current Brazilian policies. We conclude that the compromise of the State with the direction of the development and the continu-ity of industrial policies is very important to a solid building of comparative advantages in technologically dynamic sectors.

The purpose of this paper is to essentially provide a theoretical framework to industrial policies, especially showing the reasons for preference of a theoretical framework that is not based on equilibrium, and not based on maximization. We sought to define these policies, highlighting their positive results – at least potentially – in terms of some parameters (production, efficiency, productivity, income, welfare etc.). In this sense, we defined industrial policy, also analyzing the reasons for the usual lack of concern with a more rigorous theoretical framework for industrial policies. Following that, we briefly discussed whether or not a certain theory can lay the foundation for these policies, also examining if such theories are important (or not) in empirical terms. In the fourth section, we investigated the possible use of industrial policies, emphasizing market failures, public goods, non-competitive markets, externalities and technological development. Finally, we discussed about evaluation approaches of industrial and technological policies, focusing with more detail on the challenges related to the evaluation of economic effects of industrial and technological policies, and the methodologies of evaluation of these policies.

The consumers' requirements are constantly growing, as well as the concern for the environment. Considering this change of scenario, industrial companies started paying more attention to environmental issues and decided to resort to solutions such as the adoption of the Environmental Management System based on the ISO 14001 model. It is believed that the adoption of this model changes the organizational image, both internally and externally. This possible change was the focus of this research, considering that many publics related to certified companies may have the wrong idea about what being a green company really means. The objective of this study is to verify, through a survey research, the relation between the Environmental Management System based on ISO 14001 with organizational image of Brazilian firms. At first, this paper presents a theoretical review on Environmental Management System, IS0 14001, Organizational image, green Marketing, Greenwashing and Public Relations. Next, the research method is presented, as well as the results obtained through theoretical study, the research application and data analysis, and a brief analysis of the Public Relations' role in the organizational environment at issue. Finally, it presents the results obtained by tabulating the questionnaires, analysis of related data, and consideration about these
