Heterogeneity of volatile sources along the Halmahera arc, Indonesia
2021
co-auteur étranger; International audience; The parallel Halmahera and Sangihe arcs in eastern Indonesia are sites of active arc-arc collision of considerable interest in developing understanding of the geodynamics and geochemistry of subduction zones. Owing to the comparative remoteness of the region, few ground-based studies of the volcanoes have been undertaken. Here, we report and integrate gas measurements and (isotope) geochemical analyses of lava samples for Dukono, Ibu, Gamkonora, Gamalama, and Makian volcanoes of the Halmahera arc. Summing gas fluxes for all five volcanoes indicates arcscale emission budgets for H 2 O, CO 2 , SO 2 , H 2 S, and H 2 of 96300±27000, 2093±450, 944±400,…
La rigenerazione urbana delle periferie degradate: il caso emblematico della città di Palermo

Transformando las prácticas de evaluación en las agencias de innovación para fomentar transiciones hacia la sostenibilidad
2019
The aim of the study is to identify different styles and practices for evaluation of innovation policies based on different orientations, focusing on the case of the paradigm of transformative change to foster transitions towards sustainability, and the problems associated with its application. The study is exploratory, and it uses public funding agencies for innovation as strategic research settings. Based on the information provided by the experience of an international consortium participated by funding agencies from different countries, the main concepts and problems presented in the theoretical debate are illustrated. Finally, the main contributions of the study to the theory and pract…
Apporti al testo dell’Orestis Tragoedia di Draconzio nell’Ottocento
2005
I contributi testuali, un centinaio, dovuti sia a quasi tutti gli editori dell’ Orestis tragoedia di Draconzio dal 1858 al 1883, sia alle ricerche di Rothmaler (1865), L. Müller (1866) e Rossberg (1878 / 79 / 83), spesso sono abbastanza scontati, talora invece sono frutto di riflessione approfondita e lodevolmente attenta. Per le molte lacune, trasposizioni e correzioni erronee inopportunamente proposte, tuttavia, nessuna delle edizioni offre un testo accettabile dell’epillio. The textual contributions – about an hundred – produced either in the critical editions of the Dracontius’ Orestis tragoedia from 1858 to 1883, or in the works of Rothmaler (1865), L. Müller (1866) and Rossberg (1878 …
Vapor–liquid equilibrium of binary mixtures of trichloroethylene with 1-pentanol, 2-methyl-1-butanol and 3-methyl-1-butanol at 100 kPa
1999
Abstract Isobaric vapor–liquid equilibria (VLE) have been obtained for the systems trichloroethylene+1-pentanol, trichloroethylene+2-methyl-1-butanol and trichloroethylene+3-methyl-1-butanol at 100 kPa using a dynamic still. The experimental error in temperature is ±0.1 K, in pressure ±0.1 kPa, and in the liquid and vapor mole fraction ±0.001. The three systems satisfy the point-to-point thermodynamic consistency test. All the systems show positive deviations from ideality. The data have been correlated with the Margules, van Laar, Wilson, NRTL and UNIQUAC equations.
MANGANELLI SCONCLUSIONATO. UN CONVEGNO A PALERMO
2022
Il contributo illustra il carattere scientifico del convegno organizzato a Palermo il 19-20 maggio 2022 e passa in rassegna i singoli saggi dei relatori ospiti del convegno, inquadrandoli nelle varie linee di poetica dello scrittore e valorizzandone gli aspetti di originalità nel contesto degli studi su Manganelli
Isobaric vapor–liquid equilibrium for binary mixtures of 1-hexene+n-hexane and cyclohexane+cyclohexene at 30, 60 and 101.3kPa
2009
Abstract Consistent vapor–liquid equilibria (VLE) data were determined for the binary systems 1-hexene + n-hexane and cyclohexane + cyclohexene at 30, 60 and 101.3 kPa, with the purpose of studying the influence of the pressure in the separation of these binary mixtures. The two systems show a small positive deviation from ideality and do not present an azeotrope. VLE data for the binary systems have been correlated by the Wilson, UNIQUAC and NRTL equations with good results and have been predicted by the UNIFAC group contribution method.
Ultreya, suseya, Santiago!” Viaggio e spazialità ne La ballata dei pellegrini
2020
Per studiare dal punto di vista della geografia culturale alcuni aspetti del pellegrinaggio a Santiago de Compostela, in Spagna, il capitolo prende in considerazione un testo letterario, il romanzo autobiografico "La ballata dei pellegrini" della scrittrice francese Edith De La Héronnière, pubblicato per la prima volta nel 1993 e tradotto in italiano nel 2004. Il romanzo racconta l’esperienza del pellegrinaggio giacobeo effettuato dall’autrice negli anni Novanta assieme a tre compagni di viaggio partendo da un cammino francese. In particolare, attraverso l’analisi di alcune parti del testo, si indagano le modalità attraverso le quali la narrazione costruisce e descrive lo spazio fisico e si…
Understanding volcanoes in the Vanuatu arc
2016
We report the first helium isotope survey of volcanic gases, hot springs and some olivine phenocrysts along the Vanuatu island arc, from Tanna in the south to Vanua Lava in the north. Low CO2 content and low He-3/He-4 ratios in thermal fluids of Epi (4.0 +/- 0.1 R-a), Efate (4.5 +/- 0.1 R-a) and Pentecost (5.3 +/- 0.5 R-a) islands coherently indicate reduced mantle gas leakage and crustal contamination by radiogenic helium on these extinct volcanic systems of the former (Pliocene) arc. Instead, presently active Vanuatu volcanoes display He-3/He-4 and C/He-3 ratios typical of subduction-related volcanic arcs: He-3/He-4 ratios range from 6.4 +/- 0.5 Ra in southernmost Tanna and 7.23 +/- 0.09 …
Tres artistas en el exilio: Max Aub, Félix Candela y Josep Renau
2020
Three artists in exile focuses on the historical diaspora provoked by the Spanish civil war (1936- 1939), and how it influenced three prominent figures of the cultural scene of that period: the writer and typographer Max Aub Mohrenwitz (Paris, 1903-Ciudad de Mexico, 1972); the architect Félix Candela Outeriño (Madrid, 1910-Raleigh, US, 1977); and the artist Josep Renau Berenguer (Valencia, 1907-Berlín, 1982). They are the three protagonists of this article, who were simultaneously living in Mexico during the exile and who made notable contributions in the fields of arts and humanities (Max Aub), architecture (Félix Candela), and graphic design and photomontage (Josep Renau). While they were…
