Reflections on an interview with the late Prof Maria Antonia Modolo = Considerazioni su di un'intervista alla Prof Maria Antonia Modolo, recentemente scomparsa
No full textL’Autrice, ora Assistente di Ricerca presso il Dipartimento di Sanità Pubblica dell’Università degli Studi di Milano, Italia, nel periodo in cui è stata Residente presso
la Scuola di Sanità Pubblica dell’Università degli Studi di Perugia, ha avuto occasione di intervistare la Prof.ssa Maria Antonietta Modolo, una delle più significative
pioniere dell’Educazione alla Salute e della Promozione della Salute sia in Europa che in questo Paese, e suo mentore in quel momento. La Prof Modolo, recentemente scomparsa, in quell’occasione ha spiegato in dettaglio tutti gli obiettivi di queste discipline e l’impatto che possono avere sulla vita della popolazione dei paesi
sviluppati e in via di sviluppo, se applicate all’interno di un solido quadro di salute pubblica.The Author, now a Research Assistant at the Department of Public Health of the University of Milan, Italy, in the period she was a Resident of the School of Public Health of the University of Perugia, had the occasion to interview Prof Maria Antonietta Modolo, one of the most significant pioneers of Health Education and Health Promotion both in Europe and in this Country, and her mentor at that time. Prof Modolo, who recently passed away, in that occasion explained in detail all the goals of these disciplines, and the impact they can show on the life of the population of developed and developing countries, if applied within a robust public health framework
Dal clivus Scauri al vicus Capitis Africae: gli affreschi della vigna Guglielmina a Roma nei disegni dei Bartoli
Get PDFTwo frescoed room discovered on the Caelian hill during the seventeenth century and reproduced by Pietro Santi Bartoli in four drawings were published by the Comte de Caylus in his Recueil de peintures antiques (Paris, 1757). Their findspot has since been situated in the vineyard of Stefano Guglielmini (also known as the “vigna Guglielmina”), located by Lanciani on the Clivo di Scauro facing the church of SS. Giovanni e Paolo. The first room (plates XXIII, XXIV and XXV of the Recueil), discovered in 1639, became famous in art–historical studies due to the presence of portraits of a Roman family on the vaulted ceiling and due to the controversial interpretation of two lunettes with marine iconography; the second room (plate XXVI in the Recueil), less well known, is decorated with a fresco of three mythological figures, each placed in a rectangular panel.
Following archival research, the author has been able critically to re–examine both the topographical context of the find and the composition of the frescoes. This has led him to reject the traditional conclusions, hitherto conditioned by a misinterpretation of the Recueil made by the antiquary Ridolfino Venuti in the mid–eighteenth century. In the first place, the author has revised the location of Stefano Guglielmini’s vineyard: it should be situated, in his view, not on the Clivo di Scauro but on the road that ascended from the Colosseum to the Navicella. This finding then led in turn to a different topographical distribution of the frescoes: while those of the first room are to be located within the vineyard of S. Gregorio al Celio, the second fresco should be placed in the vigna Guglielmina proper. The identification of four other drawings of Bartoli based on Roman frescoes in the vigna Guglielmina in the collections of RIBA in London and Holkham Hall in Norfolk has permitted the author to understand that this latter fresco was not isolated, but must have formed part of a larger cycle that decorated the interior of a triple–apse room, probably the triclinium of a rich late–antique domus overlooking the ancient vicus Capitis Africa
Titan’s Magnetospheric and Plasma Environment
No full textTitan, Mars, and Venus are three largely unmagnetized planetary bodies with dense atmospheres that are immersed in external and highly dynamic magnetized plasma flows. Mars and Venus interact with the solar wind, whereas Titan usually interacts with the rotating magnetosphere of Saturn, and only occasionally is subject to shocked solar wind during brief excursions into Saturn's magnetosheath....Fil: Wahlund, J.-E..

Far plasma wake of Titan from the RPWS observations: A case study
No full textThe Titan's plasma wake has been investigated using observations from the Radio and Plasma Wave Science (RPWS) instrument onboard the Cassini spacecraft during one Titan flyby on December 26, 2005. The Langmuir Probe and the wideband receiver suggest a strong asymmetry of the plasma wake, which is displaced from the ideal wake. Two distinct structures are identified inbound and outbound of the flyby with significantly different electron number densities (ne). The maximum electron number density reached 14 cm(-3) on the Saturn side, connected to the sunlit ionosphere, while on the opposite side of Saturn observations indicate a density smaller than 2 cm(-3). Other derived parameters of the Langmuir probe analysis suggest also a difference in plasma composition between the two structures, where heavy and light ions dominate the Saturn and anti- Saturn side respectively. The total ion outflow is estimated at 2-7 x 10(25) ions/s assuming a cylindrical geometry for the plasma wake
Application of Methylated Diglycolamides in the EURO-GANEX Process
No full textSeveral processes for the treatment of used nuclear fuel are currently studied within the European Commission Horizon 2020 project GENIORS (grant agreement No. 730227). One option is the EURO-GANEX (Grouped Actinide Extraction) process, which aims at separating the actinides as a group without separation of individual actinides and without the need of valence state adjustment. A process based on TODGA and DMDOHEMA has successfully been demonstrated in the former SACSESS project on genuine fuel solution.[1] We currently study a new solvent system based on the methylated diglycolamide mTDDGA, in order to simplify the solvent composition and the whole process.[2] In this paper process development studies are presented, including detailed analyses of the extraction mechanism and complex formation of different diastereomers of mTDDGA and its related analogue Me2-TODGA[3], as well as the radiolytic stability of the ligand.[1] R.

Magnetic Reconnection Controls Impacts of Solar Wind Ions at Mercury's Surface : Investigation By Global Hybrid Simulations
No full textInternational audienceMESSENGER has revealed the complexity of the Hermean magnetic field which is dominated by dipolar and quadrupolar components (Anderson et al., 2012 and references therein). By contrast to other magnetized planets having large scale dynamo driven magnetic fields Mercury has a quadrupolar field large enough to reinforce the dipolar field at high northern latitudes and to shape the topology of the planetary field in the equatorial region and the southern hemisphere. Magnetic reconnection at Mercury is extremely effective for all IMF orientations [DiBraccio et al., JGR, 2013]. Global hybrid simulations by Richer et al. (2012) have demonstrated the dramatic influence of the quadrupolar field of Mercury on the topology of the Hermean magnetosphere. Then Chanteur et al. (AOGS 2014) have investigated the impacts of solar wind protons and alphas on Mercury’s surface with the same hybrid code and have presented a case study to demonstrate the importance of magnetic reconnection between the IMF and the planetary field in this process. We will present a set of different results corresponding to different configurations depending upon the IMF orientation and solar wind parameters.ReferencesAnderson, B. J., C. L. Johnson, H.
