Simulation relations, interface complexity, and resource optimality for real-time hierachical systems

Compositional schedulability analysis of hierarchical realtime systems is a well-studied problem. Various techniques have been developed to abstract resource requirements of components in such systems, and schedulability has been addressed using these abstract representations (also called component interfaces). These approaches for compositional analysis incur resource overheads when they abstract components into interfaces. In this talk, we define notions of resource schedulability and optimality for component interfaces, and compare various approaches.

An approach to health and safety in E.U. forestry operations – Hazards and preventive measures

Forestry in general and logging in particular continue to be among the three most hazardous sectors in European countries. The aim of this article is to characterize health and safety problems and solutions in E.U. forestry operations, and particularly in Portuguese operations. Forest types, production, employment and ownership are used to characterize the forest sector. Forestry accidents and health problems data are mentioned. Typical hazards associated to the nature of logging operations are systematized. Preventive measures, focused on a wide spectrum of measures, making safety considerations an integral feature of all operational activities from planning to organization to execution and supervision of work are emphasized in this article.

Future gender relations in global restructuring processes case study evidence from knowledge-intensive, manufacturing and service occupations

Global restructuring processes have not only strong implications for European working and living realities, but also have specific outcomes with regard to gender relations. The following contribution analyses in which way global restructuring shapes current gender relations in order to identify important trends and developments for future gender (in)equalities at the workplace. On the basis of a large qualitative study on global restructuring and impacts on different occupational groups it argues that occupational belonging in line with skill and qualification levels are crucial factors to assess the further development of gender relations at work. Whereas global restructuring in knowledge-based occupations may provide new opportunities for female employees, current restructuring is going to deteriorate female labour participation in service occupations. In contrast, manufacturing occupations can be characterised by persistent gender relations, which do not change in spite of major restructuring processes at the work place. Taking the institutional perspective into account, it seems to be crucial to integrate the occupational perspective in order to apply adequate policy regulations to prevent the reinforcement of gender related working patterns in the near future.

Radiometric studies on the oxidation of (U-14C) L-amino acids by drug-susceptible and drug-resistant mycobacteria

A radiometric assay system has been used to study oxidation patterns of (U-14C) L-amino acids by drug-susceptible and drug-resistant mycobacteria. Drug-susceptible M. tuberculosis (H37Rv TMC 102 and Erdman) along with the drug-resistant organism M. tuberculosis (H37 Rv TMC 303), M. bovis, M. avium, M. intracellulare, M. kansasii and M. chelonei were used. The organisms were inoculated into a sterile reaction system with liquid 7H9 medium and one of the (U-14C) L-amino acids. Each organism displayed a different pattern of amino acid oxidation, but these patterns were not distinctive enough for identification of the organism. Complex amino acids such as proline, phenylalanine and tyrosine were of no use in identification of mycobacteria, since virtually all organisms failed to oxidize them. There was no combination of substrates able to separate susceptible from resistant organisms.

Wuthering heights on the screen: exploring the relations between film adaptation and subtitling

This essay aims to confront the literary text Wuthering Heights by Emily Brontë with five of its screen adaptations and Portuguese subtitles. Owing to the scope of the study, it will necessarily afford merely a bird‘s eye view of the issues and serve as a starting point for further research. Accordingly, the following questions are used as guidelines: What transformations occur in the process of adapting the original text to the screen? Do subtitles update the film dialogues to the target audience‘s cultural and linguistic context? Are subtitles influenced more by oral speech than by written literary discourse? Shouldn‘t subtitles in fact reflect the poetic function prevalent in screen adaptations of literary texts? Rather than attempt to answer these questions, we focus on the objects as phenomena. Our interdisciplinary undertaking clearly involves a semio-pragmatic stance, at this stage trying to avoid theoretical backdrops that may affect our apprehension of the objects as to their qualities, singularities, and conventional traits, based on Lucia Santaella‘s interpretation of Charles S. Peirce‘s phaneroscopy. From an empirical standpoint, we gather features and describe peculiarities, under the presumption that there are substrata in subtitling that point or should point to the literary source text, albeit through the mediation of a film script and a particular cinematic style. Therefore, we consider how the subtitling process may be influenced by the literary intertext, the idiosyncrasies of a particular film adaptation, as well as the socio-cultural context of the subtitler and target audience. First, we isolate one of the novel‘s most poignant scenes – ‗I am Heathcliff‘ – taking into account its symbolic play and significance in relation to character and plot construction. Secondly, we study American, English, French, and Mexican adaptations of the excerpt into film in terms of intersemiotic transformations. Then we analyze differences between the film dialogues and their Portuguese subtitles.

Reflections on the legal framework for relations between cooperatives and subsidiaries.

In the light of Portuguese legal system, cooperative enterprises may include an enterprise carried out by a subsidiary, provided they conform to certain requirements. The aim of this paper is to reflect on the issue of the legal framework of the relationship between the cooperative and the subsidiary. There are several problems to be addressed in this paper: (i) How to qualify such a relationship since corresponding to mere investments made by the cooperative? Should it be classified as non-member cooperative transactions or as extraordinary activities? (ii) How to qualify such a relationship when related to the development of preparatory or complementary activities for the economic activity developed between the cooperative and its members? May we speak, in this situation, of a concept of “indirect mutuality”, as provided in other legal systems? (iii) How should we classify and what is the regime of the economic results from the activity developed by the subsidiary? We will conclude, advocating: (i) That the cooperative enterprise may include an enterprise carried out by a subsidiary if this is deemed necessary to satisfy the interests of the members; (ii) The inadmissibility of the concept of “indirect mutuality”; (iii) The inadequacy of qualifying the legal relationship between the cooperative partner (iv) The application, to the economic results coming from the activity developed by the subsidiary, of the regime provided for in the Portuguese Cooperative Code to the results from non-member cooperative transactions; (v) The economic results coming from the activity developed by the subsidiary cannot be appropriated by individual co-operators members, and so should be allocated to indivisible reserves.

Integração Energética da Unidade de Pré-destilação U-0100 da Fábrica de Aromáticos

A presente dissertação foi realizada no âmbito do Mestrado em Engenharia Química no ramo de Otimização Energética na Indústria Química, do Instituto Superior de Engenharia do Porto. O estudo energético foi desenvolvido na empresa Petrogal, S.A, na Refinaria de Matosinhos, avaliando a possível racionalização energética do processo existente na Fábrica de Aromáticos. Os objetivos propostos basearam-se na realização de uma integração energética à unidade de pré-destilação, denominada por U-0100, que se encontra instalada na Fábrica de Aromáticos. Pretende-se, de uma forma geral, o reaproveitamento máximo da energia do processo, diminuindo o recurso a utilidades externas. Para tal recorreu-se à metodologia da análise do ponto de estrangulamento, designada por tecnologia Pinch. Numa primeira fase da otimização foi necessário conhecer todo o processo em causa e os conceitos associados à tecnologia aplicada. Após contactar com o processo procedeu-se ao levantamento energético do mesmo, referente ao ano 2013. Nesta etapa foram recolhidos todos os dados considerados relevantes para a quantificação energética das correntes e das utilidades empregues. Depois da recolha efetuou-se a integração energética estabelecendo um ∆Tmin ótimo para o processo de 5°C, após uma prévia análise da influência deste parâmetro sobre os consumos. Constatou-se que atualmente o processo de separação opera com uma taxa de recuperação energética de 16,8% da energia total, sendo a restante energia introduzida por utilidades externas. Com a análise do ponto de estrangulamento concluiu-se que a unidade de pré - destilação U-0100 se encontra integrada energeticamente, não sendo essencial proceder a qualquer modificação à mesma. No entanto sugere-se como trabalho futuro um estudo técnico e económico da implementação de um pré-aquecedor de ar, necessário ao processo de combustão que se dá na fornalha H-0101. Isto tendo em vista o reaproveitamento máximo da corrente, gases de combustão, que é desperdiçada para o meio ambiente.

Tradição e tradução: festa e etnicidade entre os imigrantes açorianos nos E.U.A.

O autor analisa a recriação das Festas dos Espírito Santo pelas comunidades açorianas dos E.U.A. na viragem do século XXI, nomeadamente a tensão entre fidelidade à tradição e inovação. A retórica tradicionalista e etnomimética coexiste com um conjunto de adaptações ao novo contexto social e cultural. Nas sociabilidades subjacentes à Festa, o protagonismo de círculos sociais da terra de origem - a família, o parentesco, a freguesia - convive com a importância das novas identidades forjadas na imigração.

Tradição e tradução: festa e etnicidade entre os imigrantes açorianos nos E.U.A.

Desde finais do século XIX que se desenvolveu, nos estados norte- -americanos de Massachusetts (MA) e de Rhode Island (RI), uma importante comunidade de origem portuguesa. De acordo com o censo norte-americano de 1990, essa comunidade é composta por um total de 320.000 pessoas de portuguese ancestry. Tendo sido freqüentemente descrita como uma minoria étnica "invisível" (cf Smith, 1978), ela tem entretanto uma presença importante em cidades como Fali River e New Bedford - no sudeste de Massachusetts - ou East Providence - Rhode Island - onde representa entre 40 a 55% da população total. Chegada aos EUA em duas vagas sucessivas - a primeira situada entre 1870 e 1930, a segunda entre 1960 e 1980 - esta comunidade é originária, em cerca de 90% dos casos, do arquipélago dos Açores. Dada esta sua ascendência açoriana, os imigrantes portugueses nos EUA mantêm laços importantes com a cultura do arquipélago, que, como se sabe, ao mesmo tempo que possui bastantes pontes com a cultura portuguesa mais geral, apresenta também inúmeras particularidades.
