A imagem de Alessandro Baricco no Brasil
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
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
Evaluation of acylcarnitines with dicarboxylic acid residues as candidate markers for neurodegenerative syndromes
No full textThe role of acylcarnitines with dicarboxylic acid residues has been investigated for the first time using labelled internal standards.
The profile of acylcarnitines and amino acids is widely used in the neonatal screening, since a very long time, for the early diagnosis of metabolic disorders. The determination is performed by tandem mass spectrometry with electrospray ionization (ESI) and the semi-quantification of the different metabolites is evaluated by comparison with a suitable set of standards labeled with stable isotopes (2H and 13C). Recently some researchers suggested that these metabolites could be also markers for neurodegenerative syndromes. In this frame the role of acylcarnitines with dicarboxylic acid residues looks particularly important].
Commercially available kits containing isotopically labeled amino acids and acylcarnitines do not contain reference standards for carnitines O-acetylated with dicarboxylic acids. As we were interested to investigate this aspect, we synthesized two of these compounds with C6 and C12 dicarboxylic acid residues and containing three deuterium atoms in the carnitine moiety. The target standards have been obtained by optimized Steglich esterification reactions as butylated esters both at the carnitine and acid residue carboxylic groups. The analysis of dried blood spots was performed by the neonatal screening method by FIA-MS/MS using a precursors ion scan of m/z 85 for acylcarnitines and a neutral loss scan of m/z 102 for aminoacids.
The novel standards have been added to commercial standards of labeled acylcarnitines and used to screen about 60 samples of dried blood spots provided by volunteers both healthy and bearing some neurodegenerative diseases. In particular, 25 samples came from healthy volunteers and have benn used as control samples; 27 samples were from patients with different mitochondrial disorders and 8 were from patients affected by Amyotrophic Later Sclerosis (ALS).
The preliminary results obtained look encouraging, as shown in the figure below, even if some further experiments are needed. In particular, we could notice a general alteration of the acyl-carnitine profile for both the mithocondrial disorders and ALS, but this alteration was particularly significative for the acylcarnitines with dicarboxylic acid residues in patients affected by ALS. At present a larger scale screening is in progress in order to confirm these preliminary data
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

"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
(Z)-9-tricosene identified in rectal glands extracts of Bactrocera oleae males: first evidence of a male-produced female attractant in olive fruit fly
No full textAbstract It is well-known that Bactrocera oleae (olive fruit fly) females attract conspecific males by using 1,7-dioxaspiro[5,5]undecane (1) as the main component of their sex pheromone, and that 1 is produced in the female rectal gland. Although some authors have claimed that B. oleae males also attract females, to date no male-produced female attractants have been found in this species. In this paper, we report the first identification of a substance unique to males and able to attract females. The findings of the study include the following: (1) females responded in a bioassay to hexane extracts obtained from rectal glands of 15-day-old B. oleae males, (2) the presence of (Z)-9-tricosene (2) was consistently and unambiguously identified in these extracts using gas chromatography (GC) and GC-mass spectrometry methods, (3) in preliminary bioactivity tests, low doses (equivalent to a few males) of chemically and stereoisomerically pure synthetic (Z)-9-tricosene (2) attracted olive fruit fly females. Interestingly, compound 2, commonly called muscalure, is also a well-known component of the house fly (Musca domestica) sex pheromone
. Palladium-catalyzed syntheses of naturally occurring acetylenic thiophenes and related compounds
No full text5-(3-Buten-l-ynyl)-2,2'-bithienyl (1a), a natural product first isolated from Tagetes roots which shows nematicidal and photo-induced fungicidal activity, and 2-phenyl-5-(3-buten-l-ynyl) thiophen (1b) have been synthesized using two different methods. The first one (Method A) involves the palladium-catalyzed cross-coupling of vinyl bromide with the Grignard reagents derived from 5-ethynyl-2,2'-bithienyl (6a) and 2-ethynyl-5-phenylthiophen (6b). The second method (Method B) utilizes the coupling reaction of vinyl bromide with 6a and 6b, respectively, in the presence of a catalytic amount of (PPh3)4Pd and CuI. Such reaction, which was carried out under phase-transfer conditions employing BnEt3N+Cl- as phase transfer agent and 2.5NaqNaOH as base, has been also employed to prepare a large number of heterocyclic acetylene derivatives including some naturally-occurring compounds. The experimetal conditions of Method B allow also the direct production of heterocyclic acetylene derivatives (1) starting from 1-alkynyltrimethylsilanes (5) and organic halides (2)
Lean six sigma in a call centre : a case study
No full textThis paper, a case study, aims to illustrate the application of lean six sigma in a call centre of a service industry corporation. The study draws on process information and primary data from a real project. The study describes improvements in the operation of the call centre attributable to lean six sigma: increase in first-call resolution ratio, reduction in operator turnover and streamlining of processes. The introduction of lean six sigma into the call centre daily operations' management may have organizational benefits. Although lean six sigma has been extremely successful in the last two decades in the manufacturing sector, its applicability to the service sector has been a controversial topic. This study illustrates its application to a fast-growing area of the service sector, assisting companies in identifying areas of development for their call centres
