No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2013.Abstract : This study aims to investigate two translations of FLICTS, first children's book written by Ziraldo and first full-colored album for children produced in Brazil, with a view to discussing the different interactions between text and image that might occur within the translation of children's literature. Considered a landmark in Brazilian Children's Literature since its launch in 1969, its British version was translated by Silvia Caruana and published by the publishing house Roger Schlesinger in 1973 and its American English version was translated by Daniela Pinto, originally published by Melbooks in 1984 - subsequently also published by Editora Melhoramentos and commercialized in Brazil. The theoretical framework informing the study is based on the interface of Descriptive Translation Studies, Translation of Children's Literature and the Grammar of Visual Design. By the analyses of a multimodal corpus and a dossier about the history of this printed book, it was possible to note that the several changes along FLICTS publishing history have made up other possible readings on this work
Rodrigues parameters on dual hyperbolic unit sphere H20
No full textRodrigues parameters depend on the tangent of the half rotation angle in Euclidean space but in Dual space, dual Rodrigues parameters contain both rotation angle and distance corresponding the shortest distance between the straight lines in R-3. In this paper, we give Cayley's formula for the dual hyperbolic spherical motion and explain 3x3 type L-Dual skew symmetric matrices by using properties of this formula. Then, we obtain Rodrigues parameters of dual Hyperbolic unit sphere and show that Rodrigues parameters contain the hyperbolic rotation angle which is being between timelike lines and distance which is the minimal Lorentzian distance between the timelike lines of R-1(3)TUBITAK (The Scientific and Technological Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)The first author would like to thank TUBITAK (The Scientific and Technological Research Council of Turkey) for their financial supports during her PhD studies
Sempre este homem fatal: Otto Lara Resende, personagem de Nelson Rodrigues/ Always Writing About this Fatal Man: Otto Lara Resende, a Nelson Rodrigues’s Character
No full textResumo: Nelson Rodrigues é conhecido por ser um escritor obsessivo, reiterando muitas vezes certos temas, certos procedimentos, certos personagens. Uma de suas maiores obsessões foi seu amigo Otto Lara Resende, inúmeras vezes retratado em seus trabalhos. Este artigo analisa como o escritor mineiro é apresentado nas obras de Nelson, que estratégias são utilizadas para isso e a que serve tratar constantemente da personalidade de Otto em textos nos quais ele surge meio abruptamente em meio a outros personagens, interagindo com eles com a máxima naturalidade, ou em que é citado como protagonista de histórias exemplares ou emissor de frases marcadas por extraordinário brilhantismo verbal.Palavras-chave: Nelson Rodrigues; Otto Lara Resende; obsessão; ficção e realidade.Abstract: Nelson Rodrigues is well-known for being an obsessive writer, often reiterating subjects, procedures, and characters. One of his strongest and most recurring obsessions was his friend Otto Lara Resende, a writer and journalist who was portrayed many times in his works. This article analyzes how Rodrigues shows Resende in his writings, the strategies used in order to do that and what purpose he has in mind when he constantly explores aspects of Resende’s personality in the midst of other characters, naturallyinteracting with them, or when Rodrigues tells stories in which Resende is the protagonist or he is the author of phrases that are expression of an extraordinary verbal talent.Keywords: Nelson Rodrigues; Otto Lara Resende; obsession; fiction and reality.Resumo: Nelson Rodrigues é conhecido por ser um escritor obsessivo, reiterando muitas vezes certos temas, certos procedimentos, certos personagens.

No full textThis event is a part of LOS! (Leibniz Open Science!), the event series of the Leibniz Strategy Forum on Open Science. The workshop was held online, on May 16, 2024.In this workshop, Bruno Rodrigues will introduce you to the Nix package manager, which allows for reproducible software installations. This can be used not only to install R but also R packages from CRAN, Bioconductor, or even Github. Nix takes care of installing all the dependencies for the packages, so, for example, it will install Java if a required R package depends on it, such as {rJava}. To simplify the use of Nix, a package developed by the author and his colleague Philipp Baumann, {rix}, will be utilized.
Requirements to attend: comfortable with R and the command line. Nix needs to be already installed on the participants’ machines. See here: https://github.com/b-rodrigues/rix?tab=readme-ov-file#installing-nix for detailed instructions. The {rix} package must also be installed. As it is not on CRAN yet, you must install it from its own universe. Run the following line from an R session:

Rational identification of a colorectal cancer targeting peptide through phage display
No full textColorectal cancer is frequently diagnosed at an advanced stage due to the absence of early clinical indicators. Hence, the identification of new targeting molecules is crucial for an early detection and development of targeted therapies. This study aimed to identify and characterize novel peptides specific for the colorectal cancer cell line RKO using a phage-displayed peptide library. After four rounds of selection plus a negative step with normal colorectal cells, CCD-841-CoN, there was an obvious phage enrichment that specifically bound to RKO cells. Cell-based enzyme-linked immunosorbent assay (ELISA) was performed to assess the most specific peptides leading to the selection of the peptide sequence CPKSNNGVC. Through fluorescence microscopy and cytometry, the synthetic peptide RKOpep was shown to specifically bind to RKO cells, as well as to other human colorectal cancer cells including Caco-2, HCT 116 and HCT-15, but not to the normal non-cancer cells. Moreover, it was shown that RKOpep specifically targeted human colorectal cancer cell tissues. A bioinformatics analysis suggested that the RKOpep targets the monocarboxylate transporter 1, which has been implicated in colorectal cancer progression and prognosis, proven through gene knockdown approaches and shown by immunocytochemistry co-localization studies. The peptide herein identified can be a potential candidate for targeted therapies for colorectal cancer.Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UID/BIO/04469/2019 unit and BioTecNorte operation (NORTE-01-0145-FEDER-000004) funded by the European Regional Development Fund under the scope of Norte2020 - Programa Operacional Regional do Norte and the Project FCOMP-01–0124-FEDER-021053 (PTDC/SAU-BMA/121028/2010).

REMOÇÃO DE CO(II) E MN(II) DE SOLUÇÕES AQUOSAS UTILIZANDO A BIOMASSA R. OPACUS
No full textA busca por tecnologias alternativas e de baixo custo operacional para a remoção de metais em efluentes tem direcionado a atenção para a biossorção. Recentemente vários materiais de origem biológica, como bactérias e resíduos agro-industriais têm sido utilizados para a remoção de íons metálicos de efluentes industriais. A biossorção de metais pesados por espécies biológicas envolve vários mecanismos que, em geral, dependem das espécies biológicas utilizadas e do processamento da biomassa. O cobalto e o manganês são amplamente utilizados em muitas aplicações industriais, e consequentemente, estão presentes nos efluentes provenientes de vários processos industriais, como por exemplo na mineração e produção de ligas. O objetivo deste trabalho foi investigar a eficiência do Rhodococcus opacus, que apresenta vários grupamentos fenólicos e carboxílicos (capazes de interagir com íons metálicos em solução), como adsorvente para a remoção de Co(II) e Mn(II) de soluções aquosas, visando futuras aplicações para o tratamento de efluentes. A caracterização física da superfície do R. opacus foi realizada com MEV, potencial zeta e análises de FTIR. A biomassa, R. opacus, foi previamente tratada com 0,1 mol.L(-1) NaOH e usada em todos os experimentos de biossorção. Todos os testes de biossorção foram realizados em batelada e os parâmetros avaliados foram: pH, concentração da biomassa e do metal, tempo de contato e temperatura. Os melhores valores de pH para a biossorção de Co(II) e Mn(II) foram 7,0 e 5,0, respectivamente. Para ambos os metais estudados, a capacidade de biossorção específica foi maior em soluções contendo baixas concentrações de metais. Para os dois metais, o processo de biossorção foi melhor descrito pelo modelo de Langmuir e pelo modelo cinético de pseudo segunda ordem. Os parâmetros termodinâmicos como DeltaG, DeltaS e DeltaH foram calculados e os processos de biossorção para a remoção do Co(II) e do Mn(II) a partir de soluções aquosas foram consideradas reações endotérmicas e exotérmicas, respectivamente. Este trabalho mostra que o R. opacus pode ser aplicado para a remoção de íons de Co(II) e Mn(II) de soluções aquosas. Após 180 minutos de contato da biomassa com as soluções contendo Co(II) e Mn(II), 84 por cento e 97 por cento dos íons metálicos presentes em solução foram removidos.The search for alternative technologies and low operating cost for removal of heavy metals from effluent has directing attention to biosorption. Recently, various biological materials, such as bacteria and agro‐waste, have been used for removal of metallic ions from industrial effluents. Biosorption of heavy metals by biological species involves several mechanisms that, in general, depending on the type of specie used and biomass processing procedure. Cobalt and manganese are widely used in many industrial applications, consequently they are present in effluent derived from various industrial processes, for example: mining, alloy production. The objective of this work is to investigate the efficiency of Rhodococcus opacus, which presents various phenolic and carboxylic groups (able to interact with metal ions in solution), as an adsorbent for the removal of Co(II) and Mn(II) from aqueous solutions, aiming future applications for the treatment of effluents. Surface physical characterization of R. opacus was carried by MEV, zeta potential and FTIR analysis. The biomass, R. opacus, was previously treated with 0.1 mol.L(-1) NaOH solution and used in all biosorption experiments. All the biosorption tests were carried out in batch and the parameters evaluated were: pH, concentration of biomass and metal, contact time and temperature. The best pH value for biosorption of Co(II) and Mn(II) were 7.0 and 5.0 respectively. For both metal studied, the specific biosorption capacity was higher in solutions containing low metals concentrations. For both metals, the biosorption process was better described by the Langmuir and pseudo-second-order kinetic models. The thermodynamics parameters, such as DeltaG, DeltaS and DeltaH were calculated and the biosorption process for Co(II) and Mn(II) removal from the aqueous solutions were considered endothermic and exothermic reactions, respectively. This work shown the R. opacus can be applied for removal Co(II) and Mn(II) ions from aqueous solutions. After 180 min contact of biomass with solutions containing Co(II) and Mn(II), 84 per cent and 97 per cent of the metallic ion present in the solutions were removed

Because of the tarsal formula 3-3-3 and the occurrence in freshwater, it is certainly not part of the <i>salina</i> group. However, it cannot be assigned to either the <i>bisignata</i> or <i>hambletoni</i> groups because the wings of the only macropterous specimen available are autotomized, making it impossible to know for certain if there are three or four closed cells on the forewing. Although species with unknown condition of the forewings were previously treated tentatively as part of the <i>bisignata</i> group (Polhemus 1997; Padilla-Gil & Moreira 2013), we consider it more prudent to treat them (including the new species) as <i>incertae sedis</i> within the <i>angustipes</i> complex.</p> <p> Among South American species of the <i>bisignata</i> and <i>hambletoni</i> groups, <i>Rhagovelia leilae</i> Paiva, Rodrigues & Moreira, <b>sp. nov.</b> can be diagnosed by the following combination of characteristics: 1) body length 3.08−3.20 mm in the males and 3.20−3.36 mm in the females; 2) fore and hind coxae and trochanters yellow; 3) fore femur mostly black, with variable basal yellow marks; 4) middle trochanter dark-brown to black; 5) abdominal mediotergites II−VII with shiny black areas increasing towards the posterior segments; 6) abdominal sterna grayish-blue, with a large contrasting area medially on segment VII; 7) all trochanters and tibiae unarmed in both sexes; 8) hind femur not reaching apex of the terminalia, with a row of 6−7 spines in the males and 4−5 spines in the females; 9) abdominal laterotergites horizontal to slightly elevated, with a tuft of black setae at the posterolateral angle of the last segment in females; and 10) paramere short, suboval, and depressed at the median portion.</p> <p> Although the fore femur and middle coxa vary between our material from Maranh ã o (lighter pattern) and that from Alagoas (darker pattern), we consider this to be of intraspecific nature only, because there are many similarities in other aspects of color and structure shared by them. Variations on the color of leg segments or on the pattern of shiny abdominal areas are already known for other species of the <i>angustipes</i> complex, such as <i>R. angustipes</i> Uhler, 1894 (De Kort-Gommers & Nieser 1969; Galindo-Malagón <i>et al.</i> 2021) and <i>R. tenuipes</i> Champion, 1898 (Bacon 1956; Nieser and Polhemus 1999; Galindo-Malagón <i>et al.</i> 2021).</p> <p> Running our specimens through the keys to the <i>angustipes</i> complex from southeastern and southern Brazil (Nieser & Polhemus 1999) and from Colombia (Galindo-Malagón <i>et al.</i> 2021) ends in no logical results. However, they key to <i>R. fontanalis</i> Bacon, 1948 when using the key provided by Bacon (1956) for his <i>angustipes</i> group, which is indeed a species similar to the material at hand. The new species and <i>R. fontanalis</i> share the following features: 1) base of antennomere I, and fore and hind trochanters yellow; 2) presence of broad, shiny black spots on the dorsum of abdominal mediotergites II−VII; 3) abdominal sternum VII partially orange-brown in males; and 4) all trochanters and tibiae unarmed in both sexes. Nonetheless, there are several differences between them, including: 1) body length considerably different (3.08 mm [apterous male], 3.20 mm [macropterous male], 3.20−3.36 mm [apterous female] in the new species, <i>vs</i>. 3.45 mm [apterous male], 4.33 mm [macropterous male], 3.86 [apterous female] in <i>R. fontanalis</i>); 2) antennomeres II−III subequal in length in the new species, <i>vs</i>. II shorter than III in <i>R. fontanalis</i>; and 3) paramere longer and more acute at apex in <i>R. fontanalis</i> (compare Figs. 2A and 2B). Furthermore, Bacon (1948) did not mention the presence of a tuft of black setae on the posterolateral angle of female abdominal laterotergite VII, which is a distinctive feature in our specimens. Finally, <i>R. fontanalis</i> is endemic to Peru, where it occurs between about 450 and 900 m a.s.l.
