Comparison of polymers and ceramics in new and discarded electrical insulators: reuse and recycling possibilities

The expansion and maintenance of electricity distribution networks generates large amounts of waste, much of it in the form of discarded insulators that are not reused or recycled. This paper describes the results of tests on used and new ceramic and polymeric insulators to verify if their exposure to weathering justifies their replacement. In new and used ceramic insulators, properties such as contact angle, relative density, porosimetry, dilatometry and X-ray diffraction patterns showed no differences or the differences that were found could not be related to their use. The discarded ceramic material showed high thermal stability, an interesting characteristic for application as chamotte. It can also be reused to replace gravel used in substations. In polymeric insulators, thermogravimetry, differential scanning calorimetry and relative density test results suggest degradation of used material compared to new. This would justify their replacement and discard as waste, but they show little recycling potential.

As Melhores redações da FUVEST 2010: uma análise dialógica

This research analyzes the 53 best university entrance exams essays of 2010 of FUVEST - University Foundation for University Entrance Exams, which were published on the institution website, indicating that they were considered the best in the exam. The objective of the analysis was to identify similarities and differences between the essays, based on dialogic approach. We analyzed aspects such as: the way students addressed the subject, the language and organization of writing; the different ways of argumentation; the most used quotes; dissertation structure and the way the students considered the discourse genre writing. The study also compared the essays based on the way in which the genre is addressed in schools and pre-university preparatory courses, which gave us parameters to evaluate the extent to which this teaching can help students or otherwise confuse them. Through the analysis, we can deduce what the institution values, which helps to demystify some of the so-called known “recipes” for good writing

Avaliação das características físico-químicas e microbiológicas dos componentes fibrosos obtidos da moagem úmida de grãos de milho

Fibers are non-digestible materials by human organism, and they are insoluble in specific conditions. The corn fiber has been used as an alternative to enrich the food products for human consumption, in order to add nutritious value to this co-product. This study aimed at determining the chemical and fractions components of corn fiber, extracted by semi-wet milling in laboratory (LabF), and by semi-humid milling in industrial process (IndF); and microbiological analyses were perform in the last fraction. The fiber composition differed significantly among these two products as to moisture, ash, lipids, proteins, insoluble dietary fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose and lignin contents. The sample IndF showed microbiological parameters in compliance with the specifications for consumption. The investigated corn fiber may effectively contribute to increase the fiber intake in the diet. As the industrially processed fiber (IndF) showed compliant microbiological parameters with the specifications for food, this component might be incorporated into the food products formulation.

Babel subjetiva ou a mais completa tradução: considerações sobre Budapeste de Chico Buarque

This paper discusses aspects of Budapest, by Chico Buarque, published in 2003. In the novel, a contingency takes the protagonist, a Brazilian, to Hungary. There, involved within a culture quite distinct from his, he has experiences in a strange language, which “even the devil respects”, and with an interesting woman, who teaches him the language. Both, language and woman, turns into mirrors that refract and put his subjective experience, as babelic as the Hungarian, up side down. Considering contingency as a category from the Real (Lacan) and translation as mechanism of subjective search of a blot origin (Derrida), at the same time transcreation (Haroldo de Campos), we will pinpoint some ways to the novel reading.

Ineraction Model Between HRSV G-Protein and Flavonoids

Background: Acute respiratory infections (ARI) are the leading cause of infant mortality in the world, and human respiratory syncytial virus (HRSV) is one of the main agents of ARI. One of the key targets of the adaptive host immune response is the RSV G-protein, which is responsible for attachment to the host cell. There is evidence that compounds such as flavonoids can inhibit viral infection in vitro. With this in mind, the main purpose of this study was to determine, using computational tools, the potential sites for interactions between G-protein and flavonoids. Results: Our study allowed the recognition of an hRSV G-protein model, as well as a model of the interaction with flavonoids. These models were composed, mainly, of -helix and random coil proteins. The docking process showed that molecular interactions are likely to occur. The flavonoid kaempferol-3-O-α-L-arabinopyranosil-(2 → 1)-α-L-apiofuranoside-7-O-α-L-rhamnopyranoside was selected as a candidate inhibitor. The main forces of the interaction were hydrophobic, hydrogen and electrostatic. Conclusions: The model of G-protein is consistent with literature expectations, since it was mostly composed of random coils (highly glycosylated sites) and -helices (lipid regions), which are common in transmembrane proteins. The docking analysis showed that flavonoids interact with G-protein in an important ectodomain region, addressing experimental studies to these sites. The determination of the G-protein structure is of great importance to elucidate the mechanism of viral infectivity, and the results obtained in this study will allow us to propose mechanisms of cellular recognition and to coordinate further experimental studies in order to discover effective inhibitors of attachment proteins.

Electrical properties of highly conducting Sno2:Sb nanocrystals synthesized using a nonaqueous sol gel method

This work describes the synthesis of highly conducting antimony-doped tin oxide (ATO) nanocrystals prepared via a nonaqueous sol–gel route in the size range of 4–6 nm and provides insights into its electrical properties. The antimony composition was varied from 1 to 18 mol% and the lowest resistivity (4.0 × 10−4Ω·cm) was observed at room temperature in the SnO2:8.8 mol% Sb composition. The samples were evaluated by X-ray diffraction, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, and scanning electron microscope, and resistivity measurements were taken in the four-probe mode in the temperature range of 13–300 K. The results show highly crystalline nanoparticles in a monodisperse colloidal system, dependence on the shape of ATO nanoparticles as a function of Sb distribution, low resistivity, and semiconductor–metal transition.

Traduzir Lucano em português: ensaio de poética tradutória sincrônica

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).

Effect of calcium chloride on the pH values of several formulations of calcium hydroxide mixed with chlorhexidine digluconate

This study evaluated the effect of the addition of 5% calcium chlorite (CaCl2) on pH values in calcium hydroxide pastes (CH), with or without 2% chlorhexidine digluconate (CHX) used as vehicle, in several periods analysis. Polyethylene tubes were filled with CH mixed with water (G1), 2% CHX solution (G2) or gel (G3), or CHX solution or gel with 5% CaCl2 (G4 and G5, respectively). All tubes were individually immersed in distilled water. After 12, 24 hours, 7, 14 and 28 days, pH value was evaluated directly in water which the tubes were stored. Data were submitted to ANOVA and Tukey tests (α=0.05). In 24 hs and 14 days, pH values were similar to all groups. In 12 hs, the G1 presented lower pH value than other groups except to G4 (p < 0.05), and G4 presented lower pH value than G5 (p < 0.05). In 7 days, G1 presented lower pH value than G4 and G5 (p < 0.05). In 28 days, G1 and G5 presented lower pH values than G2 and G4 (p < 0.05) and among other groups there are no statistical differences (p > 0.05). The pH values increased in long-term analysis to all CH pastes. The association of 5% calcium chloride with 2% CHX solution as vehicle of CH paste provided a pH value increase in relation to CH mixed with distilled water. The CHX gel interfered negatively on pH value in comparison to CHX solution when mixed with CaCl2.

Memorial do fim: as várias faces de Machado de Assis

Este artículo se centra en el análisis de la novela Memorial do fim: a morte de Machado de Assis (1991), de Haroldo Maranhão. Basándose en las formulaciones teóricas de Linda Hutcheon en su Poética del postmodernismo (1991), analizamos la reelaboración paródica de la biografía de Machado de Assis presente en la novela. Esta práctica paródica, que se caracteriza por su dualidad contradictoria de la continuidad y la transgresión, es la principal característica de la narrativa posmoderna en esta novela de Haroldo Maranhão.
