A quantidade vocálica é traço fundamental da prosódia em língua latina e, embora não seja usualmente aproveitada na leitura de poemas, é o dado mais relevante de sua natureza e constituição, visto que, sem ela, não há versos na antiguidade clássica. A quantidade é, assim, fundamental para o canto poético dos pastores, praticado na poesia bucólica, cujo paradigma, instaurado por Teócrito nos Idílios, tem em Virgílio um digno continuador. Nos poemas bucólicos virgilianos, é comum o poeta retratar pastores alternando cantos entre si, forma poética conhecida como amebeu. O objetivo deste artigo é, pois, o de fazer uma leitura de tal topos literário, tendo como ponto de partida a relação intertextual que se funda na derivação genérica, de Teócrito a Virgílio, mas também e principalmente a que se obtém pela leitura integrada da prosódia e da métrica latinas ao texto poético, tendo em vista não apenas os códigos específi cos do gênero bucólico, mas sobretudo os dados que, inferidos da realidade moderna, como os que nos apresenta o lingüista e romancista Gavino Ledda, podem ser aproximados da realidade dos antigos guardadores de rebanho da Sicília – cenário comum aos dramas do universo pastoril virgiliano – ao mesmo tempo que se estuda como quantidade vocálica e ritmo verbal atuam para consubstanciá-lo e dar-lhe expressão poética característica.

Manuais de literatura ensinam que o Romantismo, centrado no eu romântico em seus conflitos e anseios libertários, rompe com os códigos clássicos da poética do Arcadismo. Em Iracema: a lenda do Ceará, Alencar narra a união da índia Iracema com Martim, o colonizador português que a fascina, e dessa união nasce Moacir, fruto da primeira miscigenação de povos em terras brasileiras. A matéria-prima que Alencar ficcionalizou tem, por um lado, o componente histórico, pois personagens como o guerreiro Martim e o índio Camarão estão registradas nos anais da história; por outro lado, a construção da heroína assenta-se em figuras femininas da mitologia grega. Essa dívida com a tradição clássica, intermediada pelo poeta latino Ovídio, o próprio José de Alencar a reconhece em carta-posfácio, onde confessa ter composto “uma heroida que tem por assunto as tradições dos indígenas brasileiros e seus costumes. (ALENCAR, 1978, p.88).

O autor discute neste livro até que ponto o ethos profissional do assistente social - ou seja, a dimensão moral e ética da atividade, e também o seu estar no mundo do ponto de vista social e cultural - conseguiu superar o conservadorismo que marcou durante décadas o projeto ético-político da categoria. De acordo com o pesquisador, os três primeiros Códigos de Ética do Assistente Social - escritos ao longo do século 20 - acabariam por levar a categoria a uma falsa consciência do seu papel social, devido aos fundamentos enraizadamente conservadores dos textos. O quadro não seria modificado com a adoção do quarto Código de Ética, de 1986, que expressava um pensamento marxista, mas de cunho fortemente mecanicista. No entanto, segundo ele, o próprio percurso sócio-histórico dos assistentes sociais na década de 1980 romperia com o conservadorismo, por meio do pensamento do marxista Antonio Gramsci. Na década seguinte um novo Código de Ética, que ainda está em vigor, juntamente com a regulamentação da profissão e com novas diretrizes curriculares, garantiria o predomínio deste projeto ético-político que afastava de vez a falsidade de consciência. A hegemonia desse projeto, conquistado democraticamente pelos assistentes sociais, já estaria a exigir, contudo, maior vigilância contra o retorno das ideias conservadoras, que estariam se reinfiltrando tanto pelos pensamentos retrógrados já de muito conhecidos pela categoria, quanto pelas teses marxistas de cunho mecanicista. A superação do conservadorismo, portanto, não deveria ser considerada totalmente consolidada pelos assistentes sociais.

Objective: This study evaluated the effect of quantity of resin composite, C-factor, and geometry in Class V restorations on shrinkage stress after bulk fill insertion of resin using two-dimensional finite element analysis.Methods: An image of a buccolingual longitudinal plane in the middle of an upper first premolar and supporting tissues was used for modeling 10 groups: cylindrical cavity, erosion, and abfraction lesions with the same C-factor (1.57), a second cylindrical cavity and abfraction lesion with the same quantity of resin (QR) as the erosion lesion, and then all repeated with a bevel on the occlusal cavosurface angle. The 10 groups were imported into Ansys 13.0 for two-dimensional finite element analysis. The mesh was built with 30,000 triangle and square elements of 0.1 mm in length for all the models. All materials were considered isotropic, homogeneous, elastic, and linear, and the resin composite shrinkage was simulated by thermal analogy. The maximum principal (MPS) and von Mises stresses (VMS) were analyzed for comparing the behavior of the groups.Results: Different values of angles for the cavosurface margin in enamel and dentin were obtained for all groups and the higher the angle, the lower the stress concentration. When the groups with the same C-factor and QR were compared, the erosion shape cavity showed the highest MPS and VMS values, and abfraction shape, the lowest. A cavosurface bevel decreased the stress values on the occlusal margin. The geometry factor overcame the effects of C-factor and QR in some situations.Conclusion: Within the limitations of the current methodology, it is possible to conclude that the combination of all variables studied influences the stress, but the geometry is the most important factor to be considered by the operator.

The Subject Cataloguing, in spite of its expres-sive historical trajectory in the information organization, has not been as discussed as the descriptive cataloguing, although they arise from the same process. Recovering the Cataloguing history, you can see that there is a dichotomy between the descriptive process and the subject one; the first one was emphasized for the developing of codes and interchange patterns. Nevertheless, the studies on subject cataloguing are essential to give bases to products for helping the searching of holdings. For this reason, based on the literature, it is discusses the subject cataloguing and the set of problems about a possible institution of rules/code that guides it.

The cataloging process, is responsible for building systems consisting of sets of interconnected elements and combined forms of representation, creating tools to facilitate the flow of information in various informational environments. It presents structures that offer favorable conditions for access to formal codes of symbolic representation and to the channels of information transfer, performing with competence the decoding and encoding of codes and rules used to represent knowledge and to describe information, documents and resources. The objective of this paper is to present the challenge of transforming operational data into consistent information, the role of the forms of representation and the mental constructions for defining the memory markers of users of catalogs. It shows as results the memory markers indicated by three categories of users for the description of a book like resource and points to the need of collaborative and cooperative work in cataloging and to the need of catalog modelling focused on the user.

Oxidative stress is related with physiopathology of diabetes mellitus type II and with its secondary complications, such as diabetic nephropathy. Thus, the purpose of this study was to examine the effects of n-acetylcysteine NAC, an antioxidant from Allium cepa, on oxidative stress, morphometrical and nutritional parameters and basal metabolism and energetic substrate utilization, serum glucose and oral glucose tolerance test (OGTT), and renal function of high-sucrose intake rats. Animals were initially divided into three groups. Rats in the control group (C; n=10) were given free access to a standard chow and water; (S; n=10) group received standard chow and 30% sucrose in its drinking water; (SN; n=5) group received standard chow and 2g/L NAC and 30% sucrose in its drinking water. After 25 days of treatments, rats were submitted to indirect calorimetry in fasted and feed states. After 30 days of treatments, rats from C and S groups were divided into four groups of five rats each. The (CC) and (SS) groups were given an intra-gastric dose 0,6mL saline (0,9%NaCl) and the (CNAC) and (SNAC) groups were treated with a intra-gastric dose of 0,6mL NAC (160g/day), and then everybody received a intra-gastric dose of glucose solution (20%) for the OGTT. Animals of S and SN groups have higher liquid consumption and lower food consumption than C group. Calorimetric analyses confirm that despite of the final body weight had not statistical difference among groups, S group have lower resting metabolic rate when compared to C and SN animals. Besides, S group has higher respiratory quotient, higher carbohydrate oxidation and lower lipid oxidation, both in fasted and feed states, than C and SN groups, evidencing the beneficial effect of NAC. Fasting plasma glucose is increased in SS and SNAC animals when compared to CC and CNAC, however SN group has glicemic level at 30 min before OGTT decreased when ...(Complete abstract click electronic access below)

On the grounds of the great advances achieved over recent years, the process HF/ERW (High-Frequency/Electric Resistance Welding)welded pipe have played an active role in the oil and gas industry for deep water applications, at high and extremely low temperatures, under high pressure and in highly corrosive environments, gradually replacing manufactured pipes by other processes. However, studies have shown that defects in the welded joints are a the leading causes of pipelines failures, which has required the determination of toughness values in this region, in compliance with the strict recommendations of the codes and standards with manufacturers and construction companies, on the oil and gas sector. As part of the validation process required toughness values, this research project focuses on a microstructural analysis in HF / ERW tubes microalloyed, steel grade API 5CT P110, designed to explore oil and gas in deep waters, the subject of strategic relevance to the country because of the recent discoveries in the Santos mega fields: Tupi and Libra (pre-salt). In this scientific work will be presented and discussed the results of mechanical tensile and Charpy, a few CTOD tests curves (showing the trend of toughness values to be obtained), and the microstructures of the base material obtained by optical microscopy, with special emphasis on the formation of nonmetallic inclusions in the welded joint

The reducionism method has helped in the clari cation of functioning of many biological process. However, such process are extremely complex and have emergent properties that can not be explained or even predicted by reducionism methods. To overcome these limits, researchers have been used a set of methods known as systems biology, a new area of biology aiming to understand the interactions between the multiple components of biological processes. These interactions can be represented by a mathematical object called graph or network, where the interacting elements are represented by a vertex and the interactions by edges that connect a pair of vertexes. Into graphs it is possible to nd subgraphs, occurring in complex networks at numbers that are signi cantly higher than those in randomized networks, they are de ned as motifs. As motifs in biological networks may represent the structural units of biological processess, their detection is important. Therefore, the aim of this present work was detect, count and classify motifs present in biological integrated networks of bacteria Escherichia coli and yeast Saccharomyces cere- visiae. For this purpose, we implemented codes in MathematicaR and Python environments for detecting, counting and classifying motifs in these networks. The composition and types of motifs detected in these integrated networks indicate that such networks are organized in three main bridged modules composed by motifs in which edges are all the same type. The connecting bridges are composed by motifs in which the types of edges are diferent
