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
Organic semiconducting single crystals as solid-state sensors for ionizing radiation
No full textSo far, organic semiconductors have been mainly proposed as detectors for ionizing radiation in the indirect conversion approach, i.e. as scintillators, which convert ionizing radiation into visible photons, or as photodiodes, which detect visible photons coming from a scintillator and convert them into an electrical signal. The direct conversion of ionizing radiation into an electrical signal within the same device is a more effective process than indirect conversion, since it improves the signal-to-noise ratio and it reduces the device response time. We report here the use of Organic Semiconducting Single Crystals (OSSCs) as intrinsic direct ionizing radiation detectors, thanks to their stability, good transport properties and large interaction volume. Ionizing radiation X-ray detectors, based on low-cost solution-grown OSSCs, are here shown to operate at room temperature, providing a stable linear response with increasing dose rate in the ambient atmosphere and in high radiation environments. © The Royal Society of Chemistry 2014
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

Solid State Organic X-Ray Detectors Based on Rubrene Single Crystals
No full textIn this work we report the results on the investigation of rubrene single crystals as solid state direct ionizing radiation detectors. With the aim to understand how electrical properties, and in particular a large charge carrier mobility, affect the radiation detection process in organic semiconducting single crystals, we compare the detection performance of rubrene-based devices with those of 1,5-dinitronaphthalene (DNN)-based ones. DNN has been recently proven to be a stable and reliable X-ray direct detector, operating at very low voltages, in air and at room temperature, with a carrier mobility values about two orders of magnitude lower than rubrene. We demonstrate here that the large charge carrier mobility of rubrene crystals does not result in a better X-rays detection performance. In fact, rubrene devices are shown to be less performing than DNN as detectors, with lower sensitivity to X-rays, poorer stability and reproducibility, and longer rise and decay times of the signa

Layered metal-organic chalcogenide thin films for flexible and large-area X-ray direct detection
No full textX-ray detection for personal dosimetry requires sensitive, stable and non-toxic materials. At the same time, scalability onto large-area and flexible substrates is emerging as a desirable property. To satisfy these requirements, novel materials to be employed as the active layer of direct X-ray detectors are needed. In this search for easy-processability, large area, efficient and non-toxic materials for direct X-ray detection, we assess the performance of a layered metal-organic chalcogenide [AgSePh]infinity, recently proposed as representative of a novel excitonic semiconductors platform. Here we demonstrate that [AgSePh]infinity can be successfully applied as direct ionizing radiation detecting layer, reaching sensitivities up to (180 +/- 10) mu C Gy-1 cm-2 and competitive limit of detection down to (100 +/- 30) nGy s-1. Moreover, it offers good stability and reproducibility of detection after 100 Gy of irradiation and upon bending to a curvature radius of 5 mm
"Muy señor nuestro Alessandro Varaldo". La ricognizione del mondo spagnolo e portoghese per riscoprire un autore italiano di successo ma dimenticato
No full textWho is Alessandro Varaldo (1876-1953)? This first analysis about what was said, adapted and translated of Varaldo’s work in the Iberian Peninsula and South America, maybe the only areas outside Italy where some traces of Italian author can be found, is a chance to go along his literary paths that overtook two temporal barriers (1900 and 1950), although it has not overtaken the oblivion’s threshold.Questa è una prima ricognizione di ciò che è stato detto, adattato e tradotto di Alessandro Varaldo (1876-1953) nella Penisola iberica e in Sud America, che si sospetta siano gli unici territori stranieri dove si riesca a ritracciare qualcosa dell’autore italiano, ed è un’occasione per ripercorrerne la traiettoria letteraria che ha superato due transenne temporali come il 1900 e il 1950 ma non quella della dimenticanza
Direct Inkjet Printing of TIPS-Pentacene Single Crystals onto Interdigitated Electrodes by Chemical Confinement
No full textOrganic semiconducting single crystals (OSSCs) are very promising for low cost
electronics, being the highest performers among organic semiconductors
in terms of charge transport, with carrier mobilities exceeding 10 cm2 V s−1.
Here, it is demonstrated how it is possible to obtain millimeter-long single crystals
of 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) onto gold
interdigitated electrodes patterned onto flexible plastic substrates, via direct
inkjet printing of precursor solutions. This result is enabled by a novel chemical
confinement strategy that exploits fluorinated thiols as solvophobic “chemical
fences”, able to avoid the printed solution spreading, thus promoting the
formation of single crystals even on highly heterogeneous surfaces, without
changing the chemical nature of the surface underlying the grown crystals.
Electrical measurements demonstrate a good electrical contact with the
electrodes. Moreover, their response UV-vis (Ultraviolet-visible) is among the
highest up to now reported for organic UV–vis photodetectors, and their performance
as direct X-ray detectors is satisfactory, confirming that the printed
crystals have an effective electrical contact with the underlying electrodes.
Since both the solvophobic fence and the TIPS crystals precursor solution are
inkjet printed on flexible substrates, this work opens novel perspectives for the
practical use of OSSCs in low cost, yet performing, flexible electronics
