No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos da Tradução, Florianópolis, 2013.Com a intenção de delinear o modo pelo qual o escritor italiano Alessandro Baricco se inseriu no sistema literário brasileiro e os caminhos percorridos pelos seus livros traduzidos, esta dissertação dá voz às experiências tradutórias de seus tradutores. A inserção de Bariccono Brasil tem seu início em 1997, através de uma proposição da Profa. Dra. Roberta Barni à editora Iluminuras da tradução de Oceano Mare. A partir daí, outras sete obras foram publicadas no Brasil, sendo três delas traduzidas por Roberta Barni e as outras quatro por quatro tradutores diferentes. De um lado, considera-se o tradutor como figura principal namediação entre culturas, e, de outro, se analisa a realidade desta figuradentro do sistema literário, sua invisibilidade, seus limites e o exercíciode sua profissão. A pesquisa conta, ainda, com críticas e resenhas referentes ao autor italiano publicadas em jornais consagrados no Brasil, considerando estas como parte constituinte da imagem de Baricco refletida em território nacional. Abstract : Intending to delineate the way the Italian writer Alessandro Baricco has been inserted in the Brazilian literary system and the paths his translated books have followed, this thesis gives voice to the translating experiences of his translators. Baricco's insertion in Brazil began in 1997, through a personal project of Dr. Roberta Barni, with her translation of Oceano Mare. Since then, seven other of his works have been published in Brazil, three of which were translated by Roberta Barni and the other four by four different translators. On the one hand,the translator is considered as the main figure in mediation betweencultures and, on the other, this figure's reality is analyzed within theliterary system: its invisibility, its limits and its professional practice. Criticisms and reviews of this Italian author published in well established Brazilian newspapers are also considered, with the understanding that they are part of Baricco's image reflected here
Isogeometric rotation-free analysis of planar extensible-elastica for static and dynamic applications
No full textFinite deformations of planar slender beams for which shear strain can be neglected are described by the extensible- elastica model, where the strain-displacement relation is geometrically exact and the Biot stress–strain relation is linear. However, if the formulation is expressed in terms of displacements without rotation, the kinematics are described by a partial differential equation involving a fourth-order spatial operator, which cannot be approximated by the classical C0-continuous FE method in the standard Galerkin framework. In this work, we propose the spatial approximation of such high-order PDE by means of NURBS-based isogeometric analysis (IGA) which allows the use of globally high-order continuous basis functions. The employed IGA approach possesses three advantages: first, it facilitates the encapsulation of the exact geometric representation of the beams in the spatial approximation with fewer discrete points, especially useful for curved structures; second, it allows the discretization of high-order spatial operators; and third, it provides an efficient numerical solution of the discrete problem by using a limited number of degrees of freedom since the employed standard Galerkin formulation does not require rotational degrees of freedom. Yet this approach has not been directly compared to appropriate analytical solutions. To this end, we compare and validate numerical results from FE with the closed-form solutions for a set of static beam problems, including a newly derived solution for an initially curved beam, based on the extensible-elastica theory, by estimating the convergence orders of the errors. We also highlight the advantages of this formulation with the numerical solution of three dynamic problems: the swinging of a pinned beam, the propagation of solitons (nonlinear waves) in post-buckled beams, and snap-through buckling of a pinned beam that is axially buckled before transverse loading
La maturità di Alessandro Fei del Barbiere, in bilico tra Maniera e Riforma
No full textThis article studies the mature career of the Florentine painter Alessandro Fei del Barbiere (1537-1592), beginning with the rediscovery of the 'Ascension' altarpiece formerly in the Albizi Chapel in the destroyed church of San Pier Maggiore, Florence. Studying this painting and others recorded in 1584 by the biographer Raffaello Borghini, such as the two altarpieces for Santa Maria delle Grazie and the Madonna dell'Umiltà in Pistoia, the author reconstructs a body of works showing how in the 1580s Fei gradually went beyond the archaic style of his apprenticeship - he had been trained by Ridolfo del Ghirlandaio and Pierfrancesco Foschi, but was also marked by the Maniera of Vasari - evolving towards naturalism in both mimesis and pictorial handling. In Florence, his development partly parallels that of Santi di Tito and his circle, but Fei was also influenced by a probable sojourn during the early part of that decade in Rome, where he could have been inspired by Girolamo Muziano and the painters working for Pope Gregory XIII. Among other proposals, the author suggests that the artist was responsible for decorating the chancel of Fiesole Cathedral (c. 1584-1589), which consisted of an altarpiece, only rarely discussed by scholars, and a cycle of frescoes hitherto attributed to Nicodemo Ferrucci
Tra socialdemocrazie e Perestrojka. Le relazioni internazionali del Pci attraverso le carte di Alessandro Natta
No full textThis essay reconstructs the foreign policy of the Italian Communist Party during the four
years of Alessandro Natta’s secretariat (1984-1988) through largely original archival documentation,
from the Alessandro Natta Fonds of the Historical Archive of the Chamber of
Deputies. Natta’s papers are also cross-referenced with those kept in the PCI Archive at the
Gramsci Foundation. The author analyses the relationship that the PCI establishes with
Gorbachev’s Perestroika, Deng’s China, and European social democracies during the last
years of the Cold War
Catalytic enantioselective alpha-amination of 2-oxindoles and a new route to the bio-active compound AG-041R
No full textAG-041R is a chiral, enantiopure 2-oxindole urea derivative provided with a remarkable bio-activity that ranges from anti-ulcer, to condrogenic and anti-proliferative.
Following the introduction by our group of a convenient protocol for the organocatalytic, asymmetric alpha-amination (AaA) of N-unprotected 3-alkyl-2-oxindoles with bis(trichloroethyl)¬azodicarboxylate (BTCEAD), we report herein a novel route to AG-041R, which takes advantage of the prompt elaboration of chiral hydrazine derivatives masked as trichloroethyl carbamates.
In addition to the optimization of the AA step and the subsequent elaboration of the resulting aminated product, the possibility to enhance the enantiomeric purity of suitable intermediates, by selective crystallization of the racemate, will be briefly discussed
Assessing the safety performace of fireproofing materials for equipment protection
No full textFire scenarios in off-shore installations have a high potential to cause severe asset damage. Moreover, cascading events triggered by fire may further escalate the magnitude of the accident, in particular if equipment units containing significant inventories of flammable materials (e.g. separators) are involved. Fireproofing is a consolidated technique for passive fire protection of units and supporting structures. However current practice in rating fireproofing materials does not provide sufficient information about the protection granted to process equipment: for example, the ‘time-to-failure’ of pressurized vessels protected by fireproofing materials, which is fundamental in planning adequate egress and emergency procedures, can not be predicted from the results of standardized fire tests. The current contribution presents the results of a study aimed at a better understanding of the performance of fireproofing materials in the protection of critical equipment. The study integrated experimental and simulation techniques. Different fireproofing materials (inorganic fiber, lightweight concrete, intumescent resin) were considered as a reference. The experimental activity was aimed at the definition of fundamental models to describe the thermo-physical properties of the materials. Since some fireproofing materials (e.g. intumescent resins) undergo significant structural changes during fire exposure, appropriate models to predict material behaviour and to link material conversion with thermo-physical properties were developed. Specific simulation models were used to describe heat transfer through the material. Finite Element Model (FEM) simulation allowed for the description of the expected behaviour of process equipment exposed to different fire conditions. The results were validated by available large scale tests on storage vessels. The study led to a better understanding of the dynamics underlying the effective design for passive fire protection. While the current practice in application of fireproofing materials was proved adequate in delaying vessel failure for most practical cases, the safety margins actually present in the design were thoughtfully explored by the application of the current simulation procedure. The criticalities and limits of use of the alternative fireproofing options were identified. The results showed as the time transients required to reach a steady-state condition in the heat transfer are significantly long in many cases. The changes in the physical properties of materials during fire exposure may play a major role on the protection performance. Such effects could not be accounted for complex geometries by traditional simplified approaches alone. Thus, the proposed approach paves the way for a safer and more cost effective design of passive fire protection systems in off-shore facilities
Gene expression profile of endothelial cells during perturbation of the gut vascular barrier
No full textIt has been widely demonstrated that tolerance against gut microbiota is compartmentalized to mucosal sites where microbes mostly reside. How the commensal bacteria are excluded from the entrance into the blood stream via intestinal capillaries that are located beneath the gut epithelium was not clear. We recently described the existence of a new anatomical structure, the ‘gut vascular barrier’ (GVB), both in murine and human intestines that plays a fundamental role in avoiding indiscriminate trafficking of bacteria from the gut into the blood circulation. The vascular barrier integrity could be altered by Salmonella typhimurium, a pathogen capable of systemic dissemination, through the modulation of the Wnt/β-catenin signaling pathway. Here we have analyzed the differences in gut endothelial gene expression profiles during Salmonella infection and have identified some interesting characteristics of endothelial to mesenchymal transition. These findings add new insights in the gut-liver axis
