Who is the author of the 1876 Stefano manuscript?
No full textFor over one hundred years the Stefano manuscript was a private document in the possession of the Baccich family and descendants. It told a story of the 1875 Stefano shipwreck as narrated by the shipwreck survivor and the founding family patriarch Miho Baccich. In these circumstances the question of authorship of the manuscript was immaterial and did not arise as an issue. However, with the publication of the manuscript the author‟s name, or names, need to be formally attributed to it. It turns out that this is not such a clear-cut matter.
As we shall see, all informed sources attributed the authorship, and the ownership, of the manuscript to Miho Baccich. But the manuscript itself was written by Canon Stjepan Skurla – a priest from Miho‟s hometown of Dubrovnik. The question then arises: should Skurla also be considered as an author of the manuscript, or, even as the sole author (as some would have it)
Peculiar karstic features in the Upper Triassic sulphate evaporites from the Secchia Valley (Northern Apennines, Italy).
No full textIn the Secchia Valley spectacular sulphate outcrops (Burano Fm., Upper Triassic) are composed mostly of gypsum, anhydrite is a minor constituent.The apparent relative dissolution rates of gypsum and anhydrite rocks are variable and result in peculiar karstic features, which have not been reported in other evaporite deposits. Such differential solution phenomenon can be observed both on the fine scale, along outcrop surfaces, and also at the large scale, controlling drainage patterns of rock masses. These peculiar solution features are the gypsum and anhydrite protrusions and the hypogean bends (“anse ipogee”).Gypsum and anhydrite protrusions. Although anhydrite is less soluble than gypsum, anhydrite-bearing rocks show variable behaviours and may be affected by dissolution to a greater extent than the gypsum rocks. Fine-grained anhydrite layers and lenses, enclosed in gypsum rocks, protrude from the surrounding gypsum, whereas the coarse-grained anhydrite rocks are more depressed. This effect is due to the presence of gypsified rims on the coarse-grained anhydrite crystals. When running water flushes the rocks, gypsum in the rims dissolves faster than anhydrite. The partially gypsified coarse-grained anhydrite is more deeply attacked because the anhydrite crystals fall away from the rock surface or are carried away by the water as gypsum rims are removed. In layers where gypsification of the anhydrite crystals is negligible, and this is the case for the fine-grained variety, the anhydrite rocks are less attacked and form protrusions relative to the gypsum layers.Hypogean bends (“anse ipogee”). The karstic systems run only at a short distance from the surface, where gypsum is dominant. The expected presence of a larger amount of less soluble anhydrite in the core of the outcrops seems to prevent the development of karstic systems cutting across the sulphate masses. The karstic drainage is concentrated along joints parallel to the valley incisions, following release fractures developed as a consequence of the dramatic drop in internal rock pressure due to rapid valley-floor deepening. Because the Secchia Valley is characterized by small streams, almost orthogonally-oriented with respect to the main valley, the karstic systems may seem to flow uphill where they intercept the joints running parallel to the Secchia valley. This peculiar effect is related to the presence of alluvial and mud-slide deposits, which act as barriers and do not allow the direct down slope resurgence of the karstic waters

Introduzione [a I cartolari del notaio Stefano di Corrado di Lavagna]
No full textSaggio introduttivo all’edizione dei frammenti dei protocolli del notaio Stefano di Corrado di Lavagna nel quale viene fatta l’analisi codicologica dei frammenti e si ricostruisce la biografia del notaio. Vengono inoltre esaminate la tipologia dei documenti, le tecniche redazionali del notaio e l’organizzazione burocratica della Chiesa genovese nella seconda metà del secolo XIII.
Introduction essay to the edition of the fragments of the protocols of the notary Stefano di Corrado of Lavagna in which the analysis of the codex fragments and reconstructs the biography of the notary is made by the author. She also examined the types of documents, the technical drafting of the notary and the bureaucratic organization of the Church of Genoa in the second half of the thirteenth century
From Lausanne to Luxembourg: the CJEU’s Seraing Judgment and the Boundaries of Sports Arbitration Under EU Law
No full textIn this expert analysis, Professor Stefano Bastianon dissects the CJEU’s landmark Seraing ruling (Case C-600/23), which reshapes the contours of sports arbitration under EU law. With particular focus on judicial review and EU public policy, the author explores how the Court balances the autonomy of arbitral mechanisms like CAS with the imperative of effective judicial protection — a judgment that could have far-reaching implications for the future of dispute resolution in sport
Recensione di Robert G. La France, Bachiacca: artist of the Medici court, Firenze, Olschki, 2008
No full textABSTRACT ITALIANO
Francesco Ubertini detto il Bachiacca ebbe scarsa fortuna critica ma questo volume di Robert G. La France colma una lacuna grave nella critica d’arte con una solida monografia in lingua inglese che prende in esame tutte le opere e i documenti di questo pittore. Stefano Colonna giudica positivamente il libro, pubblicato da Leo Olschki, limitandosi a sottolineare che alcune opere, inserite come autografe dall’autore, presentino differenti qualità.
ENGLISH ABSTRACT
Francesco Ubertini called Bachiacca has had little critical fortune, but this book by Robert G. La France fills a serious lacuna in art criticism with a solid English monograph that examines all the existing works and documents. Stefano Colonna welcomes the book published by Leo Olschki and simply points out that some of the works included by the author as autograph have a different quality
Photodegradation and Photostablization Studies of Poly(3-Butylthiophene) in the Solid State.
No full textA study to clarify the mechanism of the photochemical degradation of poly(3-alkylthiophene)s in the solid state was carried out. The isolation of two low molecular weight products allowed us to determine that the polymer, under irradiation of visible light, gives rise to singlet oxygen that will, in turn, cause oxidation of the polymeric chains. Furthermore, N-hexadecyl-N-methylaniline and 1-phenyldodecan-1-one were found to decrease the rate of polymer oxidation, the latter compound being more efficient than the former even at lower concentration. It is suggested the protective action by these substances may simply be due to their ability to act as a light screen
Heterogeneous palladium-catalysed Catellani reaction in biomass-derived gamma-valerolactone
No full textHerein, we report the unprecedented use of a heterogeneous palladium catalyst for the step-economical Catellani reaction. The substrate scope with encapsulated Pd(OAc)(2) (Pd EnCat (TM) 30) or Pd/Al2O3 proved to be broad, while the renewable biomass-derived gamma-valerolactone (GVL) was identified as an effective reaction medium. Mechanistic studies highlighted the possible heterogeneous nature of the Pd/Al2O3 catalyst, while showing that the reaction performed in the presence of Pd EnCat (TM) 30 is most likely catalysed by leached homogeneous palladium species. The heterogeneous Pd/Al2O3 catalyst can be easily recovered at the end of the reaction and efficiently reused in consecutive reaction runs
