This article aims to identify the main requirements to strengthen the railroad industry in Santa Catarina by using technology roadmapping. The railway industry is composed of carriers, manufacturers, suppliers, operators, logistics, services and education. The survey aimed to provide guidelines for the Federation of the State of Santa Catarina Industry (FIESC) to develop its strategic plan for the next eight years. Based on the survey, the roadmap defined vision, mission, a list of key concepts, drivers and actions for the Federation to support the railway industry development, since this industrial sector is still economically unrepresented when compared to other sectors in Santa Catarina. The survey also pointed out there is a strong expansion program of the railway freight and railway transport for people in Brazil, both in government and private sectors.

Este artigo objetiva identificar os principais requisitos para fortalecer a indústria ferroviária em Santa Catarina (SC), por meio da aplicação do processo de technology roadmapping. A indústria ferroviária é composta por transportadores, fabricantes, fornecedores, operadores de logística, serviços e educação. A pesquisa objetivou fornecer orientações para a Federação das Indústrias de Santa Catarina (FIESC) com a finalidade de desenvolver um plano estratégico para os próximos oito anos. Baseando-se na pesquisa, definiram-se a visão, missão e uma lista de conceitos chaves, drivers e ações para que a FIESC apoiasse o desenvolvimento da indústria ferroviária, uma vez que esta é economicamente pouco representativa em comparação com outras indústrias no estado de SC. A pesquisa apontou que há forte expansão do transporte de cargas e pessoas no Brasil, tanto nos setores governamentais quanto nos setores privados.

High Speed Train projects are exposed to risks of different natures, such as: low participation of private companies in the new railways construction, lack of skilled labor, high technology not available in the internal market, high costs with land acquisition, among others. Such risks if not managed properly can become real problems and compromise the achievement of the project objectives. The risk identification is the process of collection and description of events that can have negative effects on the project. This process should consider the project uncertainty elements in order to generate specific results. In the case of HST projects, examples of uncertainty elements are: politics, economy, environment, human resources and technology. Therefore, this study aims to present a framework for categorizing risks to be used in HST projects. Also, for each category proposed some risk examples are suggested. An overview of the first Brazil HST project is showed and the risk framework is proposed. A discussion on the risks in the first Brazil HST project are presented followed by final conclusions.

Projetos de trens de Alta Velocidade estão expostos a riscos de diversas naturezas como: baixa participação de empresas privadas na construção de novas ferrovias, falta de mão de obra especializada, tecnologia de ponta não disponível no mercado interno, altos custos com aquisição de terrenos, alto impacto ambiental, entre outros. Tais riscos senão forem gerenciados corretamente podem se tornar problemas e comprometer os objetivos do projeto. A identificação de riscos é o processo de coleta e descrição de eventos que podem ter efeitos negativos sobre o projeto. Este processo deve considerar os elementos de incerteza do projeto, a fim de gerar resultados específicos. No caso de projetos de TAV, são exemplos de elementos de incerteza: política, economia, meio ambiente, recursos humanos e tecnologia. Portanto, este estudo tem como objetivo apresentar uma estrutura para classificar os riscos a ser usada em projetos de TAV. Para cada categoria de risco, exemplos de riscos são apresentados. Uma visão geral do primeiro projeto de TAV do Brasil e seus principais riscos são mostrados. Finalmente, tem-se uma discussão sobre os principais resultados do artigo e as conclusões finais.

Modelling the Solubility of Gases in Saturated and Substituted Perfluoroalkanes

The importance of the study of fluorinated molecules is justified by the innumerous applications that these compounds are founding in many diverse and interesting areas as a consequence of their unusual properties. They are being used as substitutes for chlorinated solvents, surfactants in supercritical solvents, environmental probes, and in numerous biomedical applications. The choice of the best fluoroalkane to be used for a given application depends on its properties and in some cases, such as in biomedical applications, that choice has to be precise. Thus, the knowledge of the thermodynamic properties of these compounds is of extreme importance as well as the ability to describe and predict them at different conditions using thermodynamic models. In this work, the soft-SAFT EoS is used to describe the solubility of gases as oxygen, xenon and radon in saturated and substituted perfluoroalkanes. The conclusions reached in this work corroborate the experimental evidences reported in the literature indicating that the interaction between the oxygen and the CF3 terminal group is stronger than the interaction between the oxygen and other fluorinated groups in the molecule.
