The aim of this paper is to offer an essay of synchronous translation poetics, based on the theoretic thought of Haroldo de Campos and Antoine Berman, which highlight the relevance of translation history in the work of contemporary translators. For this purpose, starting from a close-reading of the first seven Latin hexameters of Lucan’s Pharsalia, I present a comparative study of the translations of Filinto Elisio (18th century), José Feliciano de Castilho (19th century) and Vieira (2011).

To evaluate the surface roughness and Vickers hardness of glass ionomer cements Ketac Molar® and Ketac Molar Easy Mix® (ESPE Dental AG) after brushing. Methods – After roughness and hardness tests of 14 specimens of each material, they were submitted to 30,000 brushing cycles and new analysis of roughness and hardness. Statistical analysis showed that there was no significant difference between the materials in relation to the initial roughness. Results – However, after brushing there was higher surface roughness for Ketac Molar Easy Mix®. For both materials, there was increase of hardness after brushing and the highest values were presented by Ketac Molar Easy Mix®. Conclusion – It can be concluded that, when choosing a glass ionomer cement for restoration it should be preferred to Ketac Molar, because it showed hardness similar to Ketac Molar Easy Mix, but it was less rough.

In 1954, it was celebrated the centenary of railways in Brazil. The date refers to the first section of 14.5 km of railway in Brazil (30/04/1854), in Rio de Janeiro, between Mauá and Fragoso, of the Petropolis Railway Company (Estrada de Ferro Petrópolis). Some of the texts and commemorative events indicated the symbolic values that the railroad took in the Brazilian history. Firstly, on 30.04.1954, the railway section Mauá-Fragoso and steam locomotive “Baroness” (the first used on the track) were declared national monuments(Decree No. 35,447-A, April 30, 1954). Secondly, some entities (Clube de Engenharia, Conselho Nacional de Geografia, Ministério da Viação e Obras Públicas) highlighted the importance of celebrating the Brazilian railway history and its historical significance, economic and geographical. For this, some events was occurred (the commemoration of one hundred years in Rio de Janeiro and Recife on 30.04.1954). Among the texts wrought produced, we highlight the text I Centenary of Brazilian Railroad (1954), released by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística), and the National Council of Geography (Conselho Nacional de Geografia). The emphasis given to the railway refersto the geographical perspective (territorial expansion), but also makes mention of the Barãode Mauá, the founder of Petropolis Railway Company. We aim to understand the celebration from evocations about the Brazilian railroad history and some ideas that is assigned to the railway (and the Barãode Mauá), and railway heritage (the track and the locomotive “Baroneza”). On basis of this review will seek to understand how it was reconceived the railroad memory in view of these values and material elements.

Metidos a movimentação dentária induzida. Métodos: utilizou-se 30 ratos Wistar, divididos em três grupos (GI, GII e GIII), compostos por 10 animais cada e sacrificados, respectivamente, 7, 14 e 21 dias após o início do experimento. Os valores médios individuais dos grupos experimentais foram comparados com seu respectivo controle por meio do teste Mann-Whitney. Comparou-se, também, os valores entre regiões em um mesmo período de tempo e, ainda, entre períodos de tempo diferentes em uma mesma região através da Análise de Variância (ANOVA), Kruskal-Wallis e subsequente teste de Tukey. Resultados: os grupos GI e GII exibiram a dimensão do LPD diminuída nas regiões apical da raiz mesiovestibular e cervical da raiz distovestibular, e aumentada nas regiões cervical da raiz mesiovestibular, apical da raiz distovestibular e média de ambas as raízes. Conclusão: a diminuição e o aumento da dimensão do LPD evidenciada em uma mesma raiz — mesiovestibular ou distovestibular —, caracterizou o movimento dentário no sentido de inclinação. As três regiões, apical, média e cervical, comparadas entre si em cada período de tempo, bem como os três períodos de tempo, 7, 14 e 21 dias, comparados entre si em cada região, confirmaram o movimento de inclinação em GI e GII, e a diminuição gradual da intensidade dos fenômenos de GI para GII, até o restabelecimento da normalidade dimensional em GIII.

For constituting itself a science, Psychology has coursed along way. From the time he was considered a Philosophy’s discipline until to be recognized as a legitimate science, Psychology had to devoteto the definition of its object of study, the development and refinement of theoretical-methodological frameworks and, in particular, to consolidation process of their research strategies and knowledge construction. Therefore, in order to regard the demands of the classical scientific paradigm, which is very influenced by Positivism, Psychology made use, initially, of quantitative methodology and laboratory research. This article presents some of the process of identity construction of Psychology as a science, focusing on its transition path between the quantitativist paradigm of scientific knowledge production to the qualitativist paradigm, until that is more commonly practiced nowadays: the collaborative use of these methodological strategies. For presenting the qualitative researching Psychology, we discussed, beyond its proposal and differentiation elements in relation to quantitative research, the different methods used for this mode and, in particular, the interview - which is considered the main way of data collection in surveys conducted by psychologists and, therefore, it is an important element the process of knowledge building that science, in addition to being the most qualified space for dialogue between there searcher and the research subject.
