Le riforme istituzionali nel Mediterraneo del VI sec. a.C. La nascita di uno spazio politico a Roma e ad Atene
Il proposito principale di questa ricerca è quello di presentare le riforme del VI sec. a.C. in una prospettiva allargata, che potremmo definire “mediterranea”. Questa prospettiva intende far emergere, anche attraverso un confronto fra l’esperienza romana e greca (in particolare Ateniese), influenze e condizionamenti che, in larga parte provenienti dalle sponde orientali del Mediterraneo, influirono notevolmente sulla storia di Roma, contribuendo a determinare la nascita di una sfera propriamente politica per quanto riguarda il governo cittadino. La ricerca attraverso quest’impostazione che potremmo definire comparatistica, intende vagliare similitudini e differenze tra esperienza romana ed…

Simultaneous Kepler/K2 and XMM-Newton observations of superflares in the Pleiades
2019
Flares are powerful events ignited by a sudden release of magnetic energy. With the aim of studying flares in the 125-Myr-old stars in the Pleiades observed simultaneously in optical and X-ray light, we obtained new XMM-Newton observations of this cluster during the observations of Kepler K2 Campaign 4. Our objective is to characterize the most powerful flares observed in both bands and to constrain the energy released in the optical and X-ray, the geometry of the loops, and their time evolution. We aim to compare our results to existing studies of flares occurring in the Sun and stars at different ages. We selected bright X-ray/optical flares occurred in 12 known members of the Pleiades fr…
Subphotospheric convection and magnetic activity dependence on metallicity and age: Models and tests
2001
We present an extensive study on the dependence of the convective turnover time (conv) on the stellar metallicity and age for main-sequence stars of masses 0.6{1.6 M. To this aim we have used and compared predictions by stellar models based on the classical Mixing Length Theory and models incorporating a Full Spectrum of Turbulence treatment of subphotospheric convection. We show that the metallicity eect is relevant for dG stars but negligible for dK stars, while stellar age is important when computing the turnover times for red dwarfs younger than logt 8:5 yr. A scatter by up to a factor 3 could be spuriously introduced in the activity vs. Rossby number relationships if such eects are neg…
PKM2 promotes Th17 cell differentiation and autoimmune inflammation by fine-tuning STAT3 activation
2019
Th17 cells undergo metabolic reprogramming towards glycolysis to support their differentiation and pathogenicity. Damasceno et al. report that PKM2, a glycolytic enzyme, plays a nonmetabolic role in mediating Th17 cell differentiation and autoimmune neuroinflammation by fine-tuning STAT3 activation.
Application of sequential injection analysis to pharmaceutical analysis.
2005
Sequential injection analysis is a well established tool for automation of pharmaceutical analysis. A short historical background of this technique is given as well as a brief discussion on the basic principles and potentials. The current applications of SIA in the pharmaceutical analysis are also described and discussed. The manifolds developed offer good analytical characteristics and are suitable for analysis of drug formulations, process analysis, drug-dissolution, drug-release testing and functional assays for screening potential drugs. The results obtained are in good agreement with those furnished by the application of the reference methods presented in the pharmacopoeias.
First proposal of a methodology for a preventive assessment of the acoustic impact of advanced landfills
2005
In this paper, the results of a preliminary study on the environmental noise pollution of a technologically advanced landfill to be realized in Sicily (Italy) are presented. The investigation has been carried out analysing, at the beginning, a simulating model suggested by the European Community. The method makes reference to the ISO 9613-2:1996 standard, which suggests a general method of calculation to assess the attenuation of sound during propagation outdoors. The simulation has pointed out the troubles in carrying out the noise pollution assessment of an advanced landfill, where several and different kinds of sound sources are present at the same time; it isn’t always possible, for exa…
Agamennone βουληφόρος? La sovranità alla prova del processo deliberativo
2022
Starting with the Iliad, Agamemnon is mostly depicted at the centre of dramatic deliberative situations. This feature is also present in fifth-century literature, particularly in some plays in which Agamemnon’s decision-making ability in uncertainty comes into tension with other characters in order to determine the ‘right’ decision and adequate leadership features. In this paper, I will focus on the Euripides’ play Iphigenia in Aulis (405 a.C.). In this tragedy the behaviour of the Achaean king draws our attention, as he is not equipped to handle his role and responsibilities. In the same years, also historiography is interested in the nature and risks of the deliberative process, as Thucyd…
Homaimos e syngenes. Consanguineità e identità etnica nelle Storie di Erodoto.

La nozione di consanguineità nella Archaiologhia greca di Tucidide
2019
In questo studio si prendono in esame i passi della Archaiologhia greca di Tucidide (1, 2-19) in cui si trovano riferimenti ai rapporti di parentela tra le stirpi greche, allo scopo di valutare quale fosse l’opinione dello storico ateniese in merito al ruolo ricoperto dal sentimento della consanguineità nei rapporti interstatali greci di età arcaica. Mentre la syngeneia svolse una funzione importante nella diplomazia dell’epoca della guerra del Peloponneso, nell’età precedente alle guerre greco-persiane i richiami ai legami di sangue non ebbero un’incidenza significativa, agli occhi di Tucidide, nei rapporti politici tra le comunità greche. Ciò non significa che in età arcaica la syngeneia …
