The premise of this paper is that a model for communicating the national value system must start from a strategy aimed at the identification, the cultivation and communication of values that give consistency to the value system. The analysis concentrates on the elements of such strategies and on the implications of applying a value communication program on the identity architecture of the community. The paper will also discuss the role of the national value system in the context of the emerging global culture, where the individual has the power to create his/her own hybrid cultural model.

Biodieselhas attracted considerable attention as a renewable, biodegradable, and nontoxic fuel and can contribute to solving the energy problems, significantly reducing the emission of gases which cause global warming. The first stage of this work was to simulate different alternative processes for producing biodiesel. The method used for the production of biodiesel is the transesterification of vegetable oilswith an alcohol in the presence of a catalyst. The raw materials used were palm oils and waste cooking oil. The second stage was a life cycle analysis for all alternatives under study, followed by an economic analysis for the alternatives that present minor impacts and which are more promising from an economic point of view. Finally,we proceeded to compare the different alternatives fromboth the point of view of life cycle and economic analysis. The feasibility of all processes was proven and the biodiesel obtained had good specifications. From the standpoint of life cycle analysis, the best alternative was the process of alkaline catalysiswith acid pretreatment for waste cooking oil. The economic analysis was done to the previous mentioned process and to the process that uses raw virgin oils, methanol, and sodium hydroxide. This process has lower investment costs but the process of alkaline catalysis with acid pre-treatment, whose main raw material is waste oil, is much more profitable and has less environmental impacts.

This study uses the process simulator ASPEN Plus and Life Cycle Assessment (LCA) to compare three process design alternatives for biodiesel production from waste vegetable oils that are: the conventional alkali-catalyzed process including a free fatty acids (FFAs) pre-treatment, the acid-catalyzed process, and the supercritical methanol process using propane as co-solvent. Results show that the supercritical methanol process using propane as co-solvent is the most environmentally favorable alternative. Its smaller steam consumption in comparison with the other process design alternatives leads to a lower contribution to the potential environmental impacts (PEI’s). The acid-catalyzed process generally shows the highest PEI’s, in particular due to the high energy requirements associated with methanol recovery operations.

OBJETIVO: Validar o conteúdo e avaliar a confiabilidade do instrumento Veterans Specific Activity Questionnaire, adaptado culturalmente para uso na população brasileira de cardiopatas. MÉTODOS: O instrumento foi traduzido, retrotraduzido e analisado por comitê de juízes para avaliação das equivalências semântico-idiomática e cultural. As atividades físicas indicadas no instrumento incomuns ao cotidiano da população-alvo foram substituídas. Outro comitê de especialistas analisou a equivalência metabólica das atividades substituídas. A proporção de concordância de avaliação dos juízes foi quantificada pelo Índice de Validade de Conteúdo. O pré-teste foi realizado em duas etapas (n1 e n2 = 15). A confiabilidade foi avaliada por meio do teste re-teste (intervalo de 7-15 dias, n = 50). RESULTADOS: Na avaliação das equivalências semântico-idiomática e cultural, os itens com Índice de Validade de Conteúdo < 1 foram revisados até obtenção de consenso entre os juízes. Constatou-se 100% de concordância do segundo comitê na análise da equivalência metabólica entre as atividades originais e as substituídas. Análise do teste re-teste apontou coeficiente de concordância kappa (k = 0,86; p < 0,001), sugerindo estabilidade temporal do instrumento. CONCLUSÕES: A versão validada do Veterans Specific Activity Questionnaire apresentou evidências de confiabilidade segundo critério de estabilidade temporal e conteúdo cultural adequado.

This paper intends to show the Portuguese municipalities’ commitment, since the first decade of this century, in cultural facilities of municipal management and how it provided 12 of the 18 district capitals of mainland Portugal with cultural equipment, but after all we want to know if this effort resulted in a regular, diverse, and innovative schedule. Investing in urban regeneration, local governments have tried to convert cities’ demographic changes (strengthening of the most educated and professionally qualified groups) in effective cultural demands that consolidate the three axes of development competitiveness-innovation-creativity. What the empirical study to the programming and communication proposals of those equipment shows is that it is not enough to provide cities with facilities; to escape to a utilitarian conception of culture, there is a whole work to be done so that such equipment be experienced and felt as new public sphere. Equipment in which proposals go through a fluid bind, constructed through space and discourse with local community, devoted a diversified and innovative bet full filling development axis. This paper presents in a systematic way what contributes to this binding on the analyzed equipment.

This presentation intends to show to what extent the Portuguese municipalities’ commitment, from the first decade of this century, in cultural facilities of municipal management and which has provided 12 of the 18 district capitals of mainland Portugal with equipment, resulted in a regular, diverse and innovative schedule.

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations’ memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to ‘save’ events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations’ memory.

This paper presents a complete, quadratic programming formulation of the standard thermal unit commitment problem in power generation planning, together with a novel iterative optimisation algorithm for its solution. The algorithm, based on a mixed-integer formulation of the problem, considers piecewise linear approximations of the quadratic fuel cost function that are dynamically updated in an iterative way, converging to the optimum; this avoids the requirement of resorting to quadratic programming, making the solution process much quicker. From extensive computational tests on a broad set of benchmark instances of this problem, the algorithm was found to be flexible and capable of easily incorporating different problem constraints. Indeed, it is able to tackle ramp constraints, which although very important in practice were rarely considered in previous publications. Most importantly, optimal solutions were obtained for several well-known benchmark instances, including instances of practical relevance, that are not yet known to have been solved to optimality. Computational experiments and their results showed that the method proposed is both simple and extremely effective.

A perspectiva cultural ou ritual de James W. Carey, expoente dos estudos culturais críticos nos EUA, para pensar a Comunicação, os media e o Jornalismo permanece praticamente desconhecida na língua portuguesa. Carey integra um conjunto de teóricos que, a partir da década de 1960, na Europa e nos EUA, procuraram caminhos alternativos à tradição de investigação norte-americana dominante, centrada nos efeitos, funções e usos dos mass media . Este artigo incide no ensaio fundador da sua proposta A cultural approach of communication (1975), embora não se confine ao mesmo. Três questões fundamentais são abordadas: Comunicação, Comunicação e modernidade e a visão cultural ou ritual da Comunicação. A hermenêutica crítica é a metodologia utilizada. Procura-se ir além das respostas de Carey ao seu contexto, destacando a sua contribuição para um entendimento da Comunicação como um ritual participatório no qual e através do qual os seres humanos geram, mantêm e transformam a cultura em que vivem.

The interest in zero-valent iron nanoparticles has been increasing significantly since the development of a green production method in which extracts from natural products or wastes are used. However, this field of application is yet poorly studied and lacks knowledge that allows the full understanding of the production and application processes. The aim of the present work was to evaluate the viability of the utilization of several tree leaves to produce extracts which are capable of reducing iron(III) in aqueous solution to form nZVIs. The quality of the extracts was evaluated concerning their antioxidant capacity. The results show that: i) dried leaves produce extracts with higher antioxidant capacities than non-dried leaves, ii) the most favorable extraction conditions (temperature, contact time, and volume:mass ratio) were identified for each leaf, iii) with the aim of developing a green, but also low-cost,method waterwas chosen as solvent, iv) the extracts can be classified in three categories according to their antioxidant capacity (expressed as Fe(II) concentration): >40 mmol L−1; 20–40 mmol L−1; and 2–10 mmol L−1; with oak, pomegranate and green tea leaves producing the richest extracts, and v) TEManalysis proves that nZVIs (d=10–20 nm) can be produced using the tree leaf extracts.

OBJETIVO: Realizar adaptação cultural para versão brasileira do questionário de atividade física no tempo de lazer e avaliar a validade de conteúdo, praticabilidade, aceitabilidade e confiabilidade.MÉTODOS: Foram realizadas as etapas de tradução, síntese, retrotradução, avaliação por comitê de especialistas e pré-teste, seguidos pela avaliação da praticabilidade, aceitabilidade e confiabilidade (teste-reteste). Os juízes avaliaram as equivalências semântico-idiomática, conceitual, cultural e metabólica. A versão adaptada foi submetida ao pré-teste (n = 20) e teste-reteste (n = 80) em indivíduos saudáveis e pacientes com doenças cardiovasculares, em Limeira, SP, entre 2010 e 2011. A proporção de concordância do comitê de juízes foi quantificada por meio do Índice de Validade de Conteúdo. A confiabilidade foi avaliada segundo critério de estabilidade, com intervalo de 15 dias entre as aplicações, a praticabilidade pelo tempo gasto na entrevista e a aceitabilidade pelo percentual de itens não respondidos e proporção de pacientes que responderam a todos os itens.RESULTADOS: A versão traduzida do questionário apresentou equivalências semântico-idiomática, conceitual, cultural e metabólica adequadas, com substituição de algumas atividades físicas mais adequadas para a população brasileira. A análise da praticabilidade evidenciou curto tempo de aplicação do instrumento (média de 3,0 min). Quanto à aceitabilidade, todos os pacientes responderam a 100% dos itens. A análise do teste-reteste sugeriu estabilidade temporal do instrumento (Índice de Correlação Intraclasse = 0,84).CONCLUSÕES: A versão brasileira do questionário apresentou propriedades de medida satisfatórias. Recomenda-se sua aplicação a populações diversas em estudos futuros, a fim de disponibilizar propriedades de medida robustas.
