Operazioni di pagamento tramite wallet e responsabilità da omessa applicazione della strong customer authentication
2022
Lo scritto commenta una recente decisione del Collegio di Coordinamento ABF a proposito del riparto di responsabilità tra intermediario emittente una carta di pagamento e cliente, in caso di operazioni abusivamente realizzate da terzi tramite «wallet». Il Collegio, analizzando la disciplina in tema di servizi di pagamento elettronici e di « Strong Customer Authentication », precisa come l’indagine del caso vada in primo luogo condotta verificando che l’intermediario abbia fornito la prova della corretta applicazione dell’autenticazione forte in ogni fase delle transazioni abusivamente compiute. Ove tale prova non sia fornita, egli dovrà restituire quanto dal cliente abusivamente versato. Th…
Geophysics and cultural heritage. A living field of research for Italian geophysicists
2015
If one reads the World Heritage List 2002/2003, (http:// whc.unesco.org/archive/WHList02-ENG.pdf), a datum comes out with evidence: 12 countries have 253 World Heritage Sites (WHS) and all the 125 member countries have 586 WHS. Within these 12 countries Italy has 35 WHS corresponding to about 6% of the whole, followed by Spain, 5.8%, France, 4.6%, and the tenth has less than 2% of WHS. Cultural heritage is one of the greatest riches of Italy. Europe, with China, is the land which has the most stratified history in the world, and Italy is likely to still have undiscovered settlements dating from the prehistoric age to the 18th century. Some areas are totally unexplored, others have been only…

L'analogia physis-techne in Aristotele (Fisica B, 3-9) e la teoria interventistica della causalità
2015
Ho diviso la lettura dei capitoli 3-9 del libro B della Fisica di Aristotele in due momenti: nei capitoli 3-7 viene data la definizione delle quattro cause e si pone il problema se caso e fortuna sono cause del divenire, nei capitoli 8-9 si risolve tale aporia in senso teleologico e si traggono le conclusioni sulla relazione physis-techne. La concezione interventistica della causalità sostiene che c’è uno stretto legame fra causalità e intervento umano in natura: l’idea di una relazione causale fra due eventi (uno che causa e l’altro che è causato) ha come presupposto il concetto di azione intenzionale e nasce dalla riflessione dell’uomo sul proprio operare finalizzato nella realtà. Sebbene…
Money for the Issuer: Liability or Equity?
2021
Abstract This study analyzes the nature of money through the lens of the international principles of accounting and lays the foundations of what it calls the accounting view of money (AVM). Using international accounting principles, the AVM argues that the fiat monies issued by the state (typically, cash, banknotes, and central bank money) are not debt and that in fractional reserve regimes, only a share of commercial bank money can be regarded as debt. The AVM argues, instead, that state monies and the nondebt share of commercial bank money are net wealth of their holders and net worth (equity) of their issuers and determines how the seigniorage associated with money issuance should be acc…

Joint Aqueous Solutions of Dextran and Bovine Serum Albumin: Coexistence of Three Liquid Phases
2014
The phase diagram of the system water/dextran (DEX)/BSA was measured as well as modeled. On the experimental side, cloud points were determined and the coexisting phases were analyzed. The theoretical calculations use an approach capable of describing solutions of chain polymers and of globular proteins with the same formalism. The required thermodynamic input comes from experiments concerning the binary subsystems, except for the polymer blend for which one interaction parameter had to be adjusted. Both sources of information yield the same essential features: the existence of a large composition area of immiscibility, starting from the subsystem DEX/BSA and extending well into the region …
Low-Temperature Optical Spectroscopy of Native and Azide-Reacted Bovine Cu,Zn Superoxide Dismutase. A Structural Dynamics Study
1994
The optical absorption spectra of native and N(3-)-reacted Cu,Zn superoxide dismutase (SOD) has been studied in the temperature range 300-10 K. The broad d-d bands observed in the room temperature spectrum, centered at 14,700 cm-1 (native enzyme) and at 15,550 cm-1 (N(3-)-reacted enzyme), are clearly split at low temperature into two bands each, centered at 12,835 and 14,844 cm-1 and at 14,418 and 16,300 cm-1, respectively. The thermal behavior of the 23,720 cm-1 band present in the spectrum of the native enzyme indicates that this band belongs to the His61-->Cu(II) ligand to metal charge transfer transition. Analysis of the zeroth, first, and second moments of the various bands as a functi…
Composition, crystallization conditions and genesis of sulfide-saturated parental melts of olivine-phyric rocks from Kamchatsky Mys (Kamchatka, Russi…
2020
Highlights • Parental melts of sulfide-bearing KM rocks have near primary MORB-like composition. • Crystallization of these S-saturated melts occurred in near-surface conditions. • Extensive fractionation and crustal assimilation are not the causes of S-saturation. • S content in melts can be restored by accounting for daughter sulfide globules. Abstract Sulfide liquids that immiscibly separate from silicate melts in different magmatic processes accumulate chalcophile metals and may represent important sources of the metals in Earth's crust for the formation of ore deposits. Sulfide phases commonly found in some primitive mid-ocean ridge basalts (MORB) may support the occurrence of sulfide …
Liquid/Gas and Liquid/Liquid Phase Equilibria of the System Water/Bovine Serum Albumin
2013
The thermodynamic behavior of the system H2O/BSA was studied at 25 °C within the entire composition range: vapor pressure measurements via head space sampling gas chromatography demonstrate that the attainment of equilibria takes more than one week. A miscibility gap was detected via turbidity and the coexisting phases were analyzed. At 6 °C the two phase region extends from ca. 34 to 40 wt % BSA; it shrinks upon heating. The polymer rich phase is locally ordered, as can be seen under the optical microscope using crossed polarizers. The Flory-Huggins theory turns out to be inappropriate for the modeling of experimental results. A phenomenological expression is employed which uses three adju…
