Get PDFDissertação (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

No full textBiodegradation of carbamazepine and clarithromycin by Trichoderma harzianum and Pleurotus ostreatus investigated by liquid chromatography - high-resolution tandem mass spectrometry (FTICR MS-IRMPD)
No full textIn this study, the capability of pharmaceutical biodegradation of fungus Trichoderma harzianum was evaluated through the comparison with the well-known biodegradation capability of white-rot fungus Pleurotus ostreatus. The study was performed in aqueous phase under aerobic conditions, using two of the most frequently detected drugs in water bodies: carbamazepine and clarithromycin, with concentrations commonly found in treated wastewater (4 μg/l and 0.03 μg/l respectively). For the first time, we demonstrated that T. harzianum is able to remove carbamazepine and clarithromycin. The analyses were performed by reversed-phase liquid chromatography/mass spectrometry, using high-resolution Fourier-transform ion cyclotron resonance mass spectrometry upon electrospray ionization in positive ion mode. The high selectivity and mass accuracy provided by high-resolution mass spectrometry, allowed us to identify some unknown metabolites. On the basis of our study, the major metabolites detected in liquid culture treated by T. harzianum were: 14-hydroxy-descladinosyl- and descladinosyl-clarithromycin, which are pharmacologically inactive products not dangerous for the environment
Structural characterization of major soyasaponins in traditional cultivars of Fagioli di Sarconi beans investigated by high resolution tandem mass spectrometry
No full textMajor soyasaponins, i.e., soyasaponins I, V, βg, and αg from traditional Fagioli di Sarconi beans (Phaseolus vulgaris L., ecotype Tabacchino), were analyzed by reversed-phase liquid chromatography–mass spectrometry (MS) using high-resolution Fourier transform ion cyclotron resonance (FTICR) MS on electrospray ionization in positive-ion mode. Fagioli di Sarconi beans are protected by the European Union [Commission Regulation (EC) No 1263/96] with the mark PGI (for “Protected Geographical Indication”), and are cultivated in Basilicata (southern Italy). Protonated adducts of soyasaponins I, V, βg, and αg were observed at m/z 943.5262, 959.5213, 1069.5583, and 1085.5534, respectively. Gas-phase dissociation of soyasaponins by infrared multiphoton dissociation FTICR MS was performed using a CO2 laser source at a wavelength of 10.6 μm. Most of the fragment ions were identified unambiguously by using the high-resolution and accurate mass value provided by the FTICR mass spectrometer. All soyasaponins exhibit a sequential and neutral loss of sugar moieties at relatively short irradiation times (i.e., less than 50 ms). When the pulse length was increased, a more pronounced fragmentation occurred, with several signals in the lower part of the mass spectrum. In the case of soyasaponins βg and αg, the occurrence of the conjugated product ion at m/z 127.0389 ([C6H6O3 + H]+, 2,3-dihydro-2,5-dihydroxy-6-methyl-4H-pyran-4-one) was evidenced. Coupling reversed-phase liquid chromatography with high-performance FTICR MS in combination with infrared multiphoton dissociation tandem MS proved to be very promising for the structural characterization of soyasaponins, and is also suitable for the rapid and accurate structural investigation of other saponins
Molecular formula analysis of fragment ions by isotope selective collision induced dissociation tandem mass spectrometry of pharmacologically active compounds
No full textThe purpose of this work is to explore the mass fragment characterization of commonly used drugs through a novel approach which involves isotope-selective tandem mass spectrometry (MS/MS). Collision induced dissociation (CID) was performed with a low-resolution linear-ion-trap mass spectrometer in positive electrospray ionization (ESI). Three pharmacologically active ingredients, i.e., omeprazole, meloxicam and brinzolamide, selected as model compounds in their own formulation, were investigated as a sodiated adduct [C17H19N3O3S+Na]+ (omeprazole) and as protonated adducts, [C14H13N3O4S2+H]+ and [C12H21N3O5S3+H]+, meloxicam and brinzolamide, respectively. Selecting a narrow window of 0.5 m/z units, precursor ion fragmentation by CID-MS/MS of isotopologues A+0, A+1 and A+2 was found very useful to confirm the chemical formula of product ions, thus aiding the establishment of characteristic fragmentation pathways of all three examined compounds. The correctness of putative molecular formula of product ions was easily demonstrated by exploiting the isotope peak abundance ratios (i.e., IF+0/IF+1 and IF+0/IF+2) as simple constraints in low resolution MS instrumentations
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
Ancient pottery from archaeological sites in southern Italy: First evidence of red grape product markers
No full textThe chemical analysis of tartaric acid (TA) and syringic acid (SA), as grape product markers in ancient ceramic vessels from the sites of Manduria and Torre di Satriano (southern Italy), was successfully performed. Firstly, the fragmentation behaviour of TA and SA as deprotonated molecules, [M-H]-, obtained by collision-induced dissociation, was investigated. Then, reversed-phase liquid chromatog-raphy (RPLC) with electrospray ionization (ESI) in negative ion mode, using a quadrupole linear ion trap in multiple reaction monitoring (MRM), was employed. A binary mobile phase composed of water-acetonitrile with 0.1% (v/v) acetic acid enabled the optimum ESI effciency of SA, greatly improving its identifcation when it occurs in trace amounts. Chemical analysis of ancient pottery fragments is a valid method for establishing the existence of preserved organic residues, which is valuable new evidence for the culture and customs of ancient populations, in this case those of southern Italy. The proposed RPLC-ESI-MRM method allowed a systematic investigation of ceramic fragments of both archaeological sites, thus providing positive evidence for the presence of TA and SA as grape product markers in storage vessels dating back to the ninth to third centuries BC
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
N2O and CO2 Emissions from Secondary Settlers in WWTPs: Experimental Results on Full and Pilot Scale Plants
No full textData about Greenhouse Gas (GHG) emissions from settling units in
wastewater treatment plants (WWTPs) are limited, probably because of the
increased difficulties in evaluating direct emissions when there is absence of an
induced air stream through the liquid volume (Caivano et al. 2016). Particularly,
gas samples collection is not immediate and easy due to the low off-gas flow
leaving the liquid surface.
In this study, a modified off-gas apparatus is proposed, to avoid these
experimental problems. A floating hood was connected to a blower to simulate
the wind action and encourage the gas stripping. The incoming air flow rates
were fixed to 4, 9, and 16 Nl min−1, simulating a wind velocity of 1.05, 2.36,
and 4.19 m/s, respectively, in order to measure GHG emissions from a full-scale
plant in several conditions. The same experimental conditions and a reproducible
sampling apparatus were employed to measure GHG emissions also
from a pilot plant. The monitoring of the full-scale plant shows that the concentrations
of N2O and CO2 in the off-gas change rapidly, demonstrating the
stripping effect induced by the blower air flow. A peak is reached and then a
rapidly decrease is observed, proving a gradual decrease of mass transfer phenomena.
As expected, the peak value increases with increasing the wind speed,
whereas the time at which the peak is observed decreases. Regarding the
pilot-scale plant, the results show the slow diffusion phenomena occurring in a
closed system, preventing the mass transfer from the liquid to the gaseous phase
Lab-scale investigation on remediation of sediments contaminated with hydrocarbons by using super-expanded graphite
No full textIn view of necessity to develop simple, rapid, and efficient
methods for monitoring and removal contaminants from
soil, a new graphene-based material is presented for
treatment of hydrocarbon-contaminated soils. Lab-scale
experiments on three soil matrices featured by increasing
granulometry were carried to evaluate graphene adsorption
capability, as removal efficiency. Soil samples, firstly
contaminated with different quantities of mineral
exhausted oil up to final concentrations of 12500, 25000,
50000 mgkg-1, respectively, were treated with opportune
amount of graphene. Results show as the removal
efficiency of graphene is directly proportional to
contamination level of the soil. Particularly, the best
removal efficiency (87.04%) was reached during treatment
of gravel samples at maximum contamination level using
the highest dosage of graphene, even though good results
(80.83%) were also achieved using lower
graphene/pollutant ratio. Moreover, graphene at ratio 1/10
showed worse removal efficiencies in treating sea
(81.17%) and silica sand (63.52%) than gravel. In this
study, also the thermal regeneration was investigated in
order to evaluate a possible reuse of graphene with
subsequent technical and economic advantages. Graphenetechnique
proves to be technologically and economically
competitive with other currently used technologies,
revealing the best choice for the remediation of
hydrocarbon-contaminated soils
