The plastic deformation is widely used in the metallurgical market due to its positive factors such as low prices and high speed production. Forming process products are obtained in high quality, both surface quality and mechanical properties. Friction is an importante factor in metal forming. Friction study in metal forming can be accomplished indirectly, such as the ring test of friction. Two samples of different materials being mild steel and copper alloy were used. The results showed the influence of friction in the flow behavior of the deformation of the second phase, as evidenced by standard metallography. It is observed that in the outer regions of the ring, plastic deformation occured in the radial direction. In the central region of the disc deformation occured in the direction of compression and the inner region of the ring flux lines showed a significant deformation in the radial direction towards the center of the ring

A inflamação é basicamente uma resposta de proteção tissular cuja função é proteger o organismo de micro-organismos e toxinas que promovem a lesão celular. A resposta inflamatória gera o aparecimento dos quatro sinais cardinais dor, edema, calor e rubor podendo posteriormente ocorrer a perda de função do tecido ou órgão. Os anti-inflamatórios não esteroides (AINEs) promovem sua atividade alterando a atividade de prostaglandinas (PGs), por inibição das isoformas de ciclo-oxigenases constitutivas (COX1) e induzidas (COX2). A inibição não seletiva destas enzimas (por AINEs clássicos) gera reações adversas graves, como as reações gastrointestinais, em pacientes pré-dispostos e/ou que as utilizam por um período prolongado. Os AINEs de segunda geração (inibidores seletivos de COX2), também se mostraram tóxicos, podendo causar alterações cardiovasculares. Neste sentido, o planejamento de novos compostos com atividade anti-inflamatória e destituídos de toxicidade ainda é um desafio para a química farmacêutica e medicinal. Dois derivados de ibuprofeno (AINE clássico) foram obtidos anteriormente no Lapdesf por Castro (2008) e Vizioli (2006), demonstrando atividade anti-inflamatória em modelo de inflamação aguda (edema de pata) e crônica (colite ulcerativa), destituídos de gastroulceração (VIZIOLI, 2009). Diante destes resultados o presente estudo visou à preparação dos compostos e o estudo pré-clínico de toxicidade em dose única (aguda) e em doses repetidas em camundongos, bem como as análises comportamentais, histopatológicas dos órgãos e ensaios bioquímicos. Os achados comportamentais, bioquímicos e histopatológicos permitem concluir que não foi observada toxicidade nos modelos estudados, exceto para o grupo de administração dose única de 2000 mg/kg via intraperitoneal do composto Lapdesf ibu-tau.

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.

This paper aims to discuss the Internet as a space conducive to the development of in-depth reports. The traditional media, often tied to economic and political issues, do not address issues related to collective and social satisfactorily. The emergence of alternative media is important and necessary for the development of investigative journalism, not tied to particular interests. The collective funding or crowdfunding is a financial alternative for the development of journalistic content and the Agência Pública de Reportagem e Jornalismo Investigativo figures as a medium that uses this feature, among others. The analysis of reports produced by the agent allows you to identify aspects of analytical and investigative construction this vast medium that is the Internet

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.
