Riflessioni sull’iconografia funeraria lilibetana nell’età di Cicerone
2021
Twenty-four, and possibly twenty-five painted stelae and aediculae were found, in different times, in the area of the necropolis of Lilybaeum (1903, 1974-1984), and further North, nearer to the ancient sea-shore (1895); most recently, two new entries enhanced the Museo Lilibeo (2009), beside two elements from decorated epitymbia. Despite previous scholarly opinions spread these artifacts over three centuries, as a whole, they can be assigned approximately to Cicero’s time. Some cross-cutting features, as a matter of fact, connect the stelae and the “Salinas” aediculae, and indicate that both date between the late 2nd and the late 1st century BC. Nevertheless, they constitue two neatly diffe…
iTeXMac: An Integrated TeX Environment for Mac OS X
2004
iTeXMac is an integrated suite of three major components: a text editor detailed in section 2, a PDF viewer detailed in section 3, and a TeX front end detailed in section 4. Some notes on installation are followed by remarks concerning inter-application communication in section 6 for other Mac OS X developers. Finally, the pdfsync feature and the TeX Wrapper are discussed in sections 7 and 8. Since they concern the synchronization between the TeX source and PDF output, and a definition for a shared TeX document structure, both will certainly interest the whole TeX community.
The degradation of intracrystalline mollusc shell proteins: a proteomics study of Spondylus gaederopus.
2021
Mollusc shells represent excellent systems for the preservation and retrieval of genuine biomolecules from archaeological or palaeontological samples. As a consequence, the post-mortem breakdown of intracrystalline mollusc shell proteins has been extensively investigated, particularly with regard to its potential use as a "molecular clock" for geochronological applications. But despite seventy years of ancient protein research, the fundamental aspects of diagenesis-induced changes to protein structures and sequences remain elusive. In this study we investigate the degradation of intracrystalline proteins by performing artificial degradation experiments on the shell of the thorny oyster, Spo…
Real-time Control of Metallurgic Processes
1996
The careful control of the liquid metal solidification and the solid shell growth is of central importance in all metallurgic processes. These have a considerable influence on the formation of cracks and other defects which can be formed in the cast material. To ensure defect free products, the liquid metal is to be cooled down according to a pattern which depends i.e. on metal grade, product dimension, cooling speed and machine design. On the other hand, the control of the liquid/solid interface is a key element in optimising the liquid solidification with respect to good productivity. So, the heat transfer plays a very important role in metallurgic casting processes, especially when casti…
La nomina di Lodovico Mortara a primo presidente della Corte di Cassazione romana
2019
L’autore, prendendo spunto da un recente libro di Massimiliano Boni e da un articolo pubblicato sul Giornale d’Italia del 30 aprile 1915, ricostruisce la vicenda della tormentata “corsa” di Lodovico Mortara per la presidenza alla Cassazione romana. Ricostruisce anche taluni aspetti della personalità di Mor- tara e degli altri magistrati coinvolti, prendendo in esame le diverse ipotesi circa la possibile paternità dell’articolo sopra menzionato. The author, taking the cue from a recent book by Massimiliano Boni and from an article published in the Giornale d’Italia (April, 30th, 1915), recon- structs the story of the tormented “race” of Lodovico Mortara for the presi- dency of the Roman Cass…
Vanishing of certain cuts or residues of loop integrals with higher powers of the propagators
2019
Starting from two-loops, there are Feynman integrals with higher powers of the propagators. They arise from self-energy insertions on internal lines. Within the loop-tree duality approach or within methods based on numerical unitarity one needs (among other things) the residue when a raised propagator goes on-shell. We show that for renormalised quantities in the on-shell scheme these residues can be made to vanish already at the integrand level.
Effect ofmconbquark chromomagnetic interaction and on-shell two-loop integrals with two masses
1999
The effect of non-zero c quark mass on b quark HQET Lagrangian, up to 1/mb level, is calculated at two loops. The results are expressed in terms of dilogarithmic functions of mc/mb. This calculation involves on-shell two-loop propagator-type diagrams with two different masses, mb and mc. A general algorithm for reducing such Feynman integrals to the basis of two nontrivial and two trivial integrals is constructed.
The youngest Trigoniida (Mollusca, Bivalvia) of Europe, including new genera and species from the type area of the Maastrichtian Stage
2022
Until recently, only a single species of trigoniid bivalve was known from the upper Maastrichtian Maastricht Formation in the type area of the Maastrichtian Stage (south-east Netherlands and adjacent Belgian and German territories); it was named Trigonia maestrichtiana by Alphonse Briart in 1888. This common, rather small species is here transferred to the genus Oistotrigonia, and a lectotype is designated. In addition, two new genera of very small rutitrigoniids, Wolfgangella and Anniedhondtella, and three new species, W. neilpearti, W. ignota and A. rieui, are erected. Most of the material available is preserved as (paired) external and internal moulds in a nearshore facies of indurated b…
Open-shell doublet character in a hexaazatrinaphthylene trianion complex
2015
Three-electron reduction of hexaazatrinaphthylene (HAN) with a magnesium(I) reagent leads to [(HAN){Mg(nacnac)}3] (1), containing a [HAN]3– ligand with a spin of S = ½. Ab initio calculations reveal that the [HAN]3– ligand in 1 has a groundstate wave function with multiconfigurational properties, and can be described as a triradicaloid species with a small amount of open-shell doublet character. peerReviewed
Surface Chemistry Controls Magnetism in Cobalt Nanoclusters
2016
Magnetic properties of Co13 and Co55 nanoclusters, passivated by surface ligand shells that exhibit varying electronic interactions with the metal, are studied using density functional theory. The calculations show that the chemical nature of the bond between the ligand and the metal core (X-type or L-type) impacts the total magnetic moment of Co nanoclusters dramatically. Furthermore, the chemical identity of the ligand within each binding motif then provides a fine handle on the exhibited magnetic moment of the cluster. Thus, ligand shell chemistry is predicted to not only stabilize Co nanoclusters, but provide a powerful approach to control their magnetic properties, which combined enabl…
