Prefácios e notas do tradutor: tensão e acolhimento na relação com o outro

The purpose of this paper is to examine the paratexts, mainly prefaces and notes, written by translators on writings of foreigners' travels in Brazil, with the purpose of evidencing which perspective guided their translations, if the perspective of the foreign author is adopted or if it is that of the domestic reader. The works examined were published by the Brazilian publishing house Companhia Editora Nacional in the Brasiliana Colllection. Most of the translators adopted a welcoming discourse to the author in their prefaces, but their prefaces, translations and notes reveal a certain tension between what they stated and what was effectively done, with moments of rupture in which the author's meanings are questioned and even denied. According to my analysis, this happens because the several forces acting on the translation, the author, the translator and the text to be translated, the languages involved, the reader are not working linearly, but in constant tension. As a result, different perspectives are adopted in different translations, but in the same translation there are moments in which the foreign pole is privileged and moments in which the domestic pole emerges.

Caracterização do fator de intensidade de tensão em corpos trincados através do método dos elementos finitos

The industry generally has sought materials with high mechanical resistance, low density, thermal stability and corrosion resistance. In the aerospace industry, for example, the use of aluminum alloys, such as Al 2024-T351 and Al 7075-T7351, have become essential. However, the use of these materials often do not resulted in a satisfactory performance of the component, since the presence of cracks can cause total rupture of the component, even with a tension below the yield stress of the material, unexpectedly. In this work, these aluminum alloys were analyzed and samples were modeled by the finite element method. Moreover, in the models were applied two different types of cracks, central and edge crack, a vertical force was applied to result in a tension 70% of the yield stress of the material analyzed. Through stress asymptotic distribution in the region near the crack tip were calculated the values of the stress intensity factors for each crack length, after the stress intensity factors characterized were compared graphically with the values of fracture toughness found in the available literature

Medo, tensão e vergonha: representações negativas de sexualidade na seção sexo da revista Capricho

The magazines destined to the adolescent public are many times searched as a resource of information about sexuality, body, relationships and adolescence. The Capricho magazine is a biweekly feminine magazine directed to teenagers. In this qualitative-descriptive study it was made the content analysis of the section about sex of 18 editions published in 2010 with the aim of identifying and discussing the predominant representations of sexuality. It was identified the predominance of negative representations, like relations between sexuality and fear, tension, shame and beauty imperatives. It can be detached that the feminine sexuality is not approached through its pleasant, positive and health aspects, but through negative representations that, instead of being discussed, are naturalized, put as normal and expected by the magazine’s discourse.

Contaminación microbiana en las líneas de agua de las unidades odontológicas

Introduction and Objective: Microorganisms are responsible for multiple infections and pathologies; this is why it is important to control microbes that can be found in the triple syringe used for irrigation in different dental procedures. The aim of this study was to identify cultivable species of microbes (fungus and bacteria) found in some dental units water lines of a private dental clinic from Medellín, Colombia. Materials and Methods: Random samples were taken from 11 chairs from a total of 89; a sample of water of 500ml was collected from the triple syringe of each selected chair. The study aim to search for the presence of total coliforms, filamentous fungi and leavened Results: the average presence of microorganisms was between 40CFU and more of 200 CFU. Microorganisms such as Aeromona salmonicida, Actinobacilus sp and Pseudomona maltophil were isolated. No total coliforms neither fecal coliforms were found. Conclusions: the high levels of contamination suggest that there is a mature biofilm in somewhere of the dental unit water line, but the absence of total and fecalis coliforms suggest that the water had been treated.

Metodologia para avaliação da deposição em pulverizações

O trabalho teve como objetivo o desenvolvimento de uma metodologia de avaliacao qualitativa e quantitativa, com o uso de substancia tracadoras, nos estudos de deposicao em pulverizacao, com a possibilidade de variacao da tensao superficial da calda. Plantas de citros foram pulverizadas com solucao tracadora composta pelo corante Azul Brilhante na concentracao de 0,15% em mistura com o Saturn Yellow tambem a 0,15%, suspenso com o lignosulfonato Vixilperse a 0,015%. A pulverizacao foi realizada com turboatomizador Jacto, na velocidade de deslocamento de 2,8 km/h e volume de calda de 1830 L/ha. A tensao superficial da solucaotracadora pulverizada foi ajustada para 72,6 mN/m, mesma da agua, e com a reducao para 36,5 mN/m. Para as avaliacoes dos depositos, dividiu-se a planta em 12 setores, partes baixa, media e alta, coletando-se amostras nas partes externa e interna e nas posicoes frontal e perpendicular a pulverizacao. Em cada posicao de coleta na planta foram retiradas duas amostras de folhas, uma constituida de 10 folhas para avaliar a distribuicao e o deposito total de ambas as superficies das folhas, e outra com 6 folhas para avaliar a relacao do deposito individual entre as superficies inferior (abaxial) e superior (adaxial) das folhas. O escorrimento de calda para o solo foi avaliado colocando-se placas de petri, distanciadas de 20 cm entre si e linearmente, sob a projecao da copa, nos setores frontal e perpendicular a pulverizacao. Para cada tensao superficial testada coletou-se amostras em 5 plantas, considerando-se cada planta uma repeticao. A avaliacao qualitativa foi feita atraves da visualizacao da distribuicao do deposito sob luz ultravioleta e a determinacao da quantidade depositada atraves da espectrofotometria. A metodologia desenvolvida mostrou-se adequada para avaliacao dos depositos de pulverizacoes no campo, com a solucao tracadora, pela possibilidade de avaliar qualitativa e quantitativa

Controle flexível para conversores monofásicos conectados a sistemas elétricos distorcidos de baixa tensão

This paper presents a technique to add flexibility in the control of power electronic converters. The power converter can function as an active power filter, as a local power source interface or perform both functions i. e. mitigate current disturbances and inject power into the grid simultaneously, configuring it as a multifunctional device. The main goal is to extract the full capability of the grid connected power electronic converter to achieve maximum benefits. To achieve this goal, the orthogonal current decomposition of the Conservative Power Theory is used. Each orthogonal current component is weighted by means of different compensation factors (k_i), which are set instantaneously and independently, in any percentage by means of the load performance factors (λ_i), providing an online flexibility in relation to compensation objectives. Finally, to validate the effectiveness and performance the proposed approach, simulations and experimental results are presented.
