A prosa brechtiana: rupturas e poéticas do entre-lugar literatura e teatro

Bertolt Brecht é genuinamente um homem da arte, envolvido com questões políticas tanto do seu país como da humanidade. Reconhecido pelas suas mudanças no campo da prática teatral, foi um dos maiores expoentes do teatro épico, suas peças de teatro e poesias criticavam o regime nazista. Antevendo a escalada de violência, um dia após o incêndio do Reichstag, deixou a Alemanha, foi neste contexto em que produziu seus mais importantes textos de dramaturgia e poesia. Embora tenha sido esta a produção que lhe consentiu reconhecimento, Brecht escreveu textos em prosa. Investigar os predicativos dessa literatura é a pergunta que se pretende responder nesta dissertação. Para responder a este problema foram estabelecidos quatro eixos de pesquisa: (i) da transversalidade da teoria do método brechtiano; (ii) definição literária imprecisa; (iii) presença de intertextualidade e (iv) diálogo entre ficção e factualidade. Como base para o objeto de pesquisa incluem-se os livros: Histórias do Sr. Keuner; Os negócios do sr. Júlio César; Romance dos três vinténs; Diário de trabalho e Conversas de Refugiados. Trata-se de uma análise apoiada no suporte bibliográfico da teoria da literatura, da teoria crítica, da filosofia e do teatro, configura-se como um estudo transartístico e transdisciplinar, buscando identificar bem como apontar as formas de aproximação da zona limítrofe entre o teatro e literatura, suas trocas e contribuições para a constituição das especificidades dos textos em prosa de Brecht. A partir das análises, foi possível confirmar que as seis obras pesquisadas apresentam características dos quatro eixos de trabalho supracitados. Algumas de forma isolada, em maior ou menor grau, e outras que articularam mais de um eixo de trabalho. Na conclusão, emito considerações importantes diante dos acontecimentos que se desenrolaram a partir ano de 2018, evidenciando a importância da pesquisa de Brecht não somente para o campo da arte, mas, também, para a sociedade e para a democracia.Bertolt Brecht es un auténtico hombre de arte, comprometido con las cuestiones políticas de su país y de la humanidad.

An extended Kalman filter approach for accurate instantaneous dynamic phasor estimation

This paper proposes the application of a non-linear Extended Kalman Filter (EKF) for accurate instantaneous dynamic phasor estimation. An EKF-based algorithm is proposed to better adapt to the dynamic measurement requirements and to provide real-time tracking of the fundamental harmonic components and power system frequencies. This method is evaluated using dynamic compliance tests defined in the IEEE C37.118.1-2011 synchrophasor measurement standard, providing promising results in phasor and frequency estimation, compliant with the accuracy required in the case of off-nominal frequency, amplitude and phase angle modulations, frequency ramps, and step changes in magnitude and phase angle. An important additional feature of the method is its capability for real-time detection of transient disturbances in voltage or current waveforms using the residual of the filter, which enables flagging of the estimation for suitable processing

Power quality in DC distribution networks

This paper presents an overview of power quality in low-voltage DC distribution networks. We study which of the power quality disturbances in AC networks are also relevant in DC networks, as well as other disturbances specific to DC networks. The paper reviews the current status of international regulations in this topic and proposes different indices for the detection and characterization of the main types of power quality disturbances, presenting some results obtained in different laboratory tests in DC networks using different DC voltage shapes delivered by different DC power source types

Simplified Mathematical Modeling of Uncertainty: Cost-Effectiveness of COVID-19 Vaccines in Spain

[EN] When exceptional situations such as the COVID-19 pandemic arise and reliable data is not available at decision-making times, estimation using mathematical models can provide a reasonable reckoning for health planning. We present a simplified model (static but with two-time references) for estimating the cost-effectiveness of the Covid-19 vaccine. A simplified model provides quick assessment of the upper bound of cost-effectiveness, as we illustrated with data from Spain, and allows for easy comparisons between countries. It may also provide useful comparisons among different vaccines at the marketplace, from the perspective of the buyer. From analysis of this information, key epidemiological figures, and costs of the disease for Spain have been estimated, based on mortality. The fatality value is a robust data that can alternatively be obtained from death registers, funeral homes, cemeteries, and crematoria. Our model estimates the cost-effectiveness ratio (ICER) to be 5,132 € (4,926 ¿ 5,276) as of 17 February 2021, based on the following assumptions/inputs: an estimated cost of 30 euros per dose (plus transport, storing, and administration), two doses per person, efficacy of 70% and coverage of 70% of the population. Even considering the possibility of some bias, this simplified model provides confirmation that vaccination against COVID-19 is highly cost-effective.Marco-Franco, JE.; Pita-Barros, P.; González-De Julián, S.; Sabat, I.; Vivas-Consuelo, D.

Characterization of Acrocarpus fraxinifolius wood submitted to heat treatment

Aiming to provide greater visibility for the wood species Acrocarpus fraxinifolius, the present study sought to analyze the influence of heat treatment on an industrial scale applied to wood species, also popularly known as Indian cedar. The heat treatment was carried out in an autoclave, with temperature and pressure control, and with saturated steam injection, for temperatures 155 ºC, 165 ºC, 175 ºC, and 185 ºC. Physical, chemical, and mechanical tests were carried out for the analyzed wood. The content of holocellulose and total lignin decreased, while the content of extractives showed a substantial increase. The density increased after the heat treatment, however the treated wood showed cracks, and these cracks influenced the significant loss of the values of the mechanical properties of compression, tension, and flexion. The shear showed strength gain for the temperature of 155 ºC, and the wood treated at 165 ºC was equivalent to untreated wood. The woods submitted to temperatures of 175 ºC and 185 ºC presented strength losses. The heat treatment in question contributes to increase the visibility, use and market value of wood

COVID-19, Fake News, and Vaccines: Should Regulation Be Implemented?

[EN] We analysed issues concerning the establishment of compulsory vaccination against COVID-19, as well as the role of misinformation as a disincentive-especially when published by health professionals-and citizen acceptance of measures in this regard. Data from different surveys revealed a high degree of hesitation rather than outright opposition to vaccines. The most frequent complaint related to the COVID-19 vaccination was the fear of side effects. Within the Spanish and European legislative framework, both compulsory vaccination and government regulation of FN (Fake News) appear to be feasible options, counting on sufficient legal support, which could be reinforced by additional amendment. However, following current trends of good governance, policymakers must have public legitimation. Rather than compulsory COVID-19 vaccination, an approach based on education and truthful information, persuading the population of the benefits of a vaccine on a voluntary basis, is recommended. Disagreements between health professionals are positive, but they should be resolved following good practice and the procedures of the code of ethics. Furthermore, citizens do not support the involvement of government authorities in the direct control of news. Collaboration with the media and other organizations should be used instead.Marco-Franco, JE.; Pita-Barros, P.; Vivas-Orts, D.; González-De Julián, S.; Vivas-Consuelo, D. (2021).
