In viaggio con Stravinsky, gli ultimi anni di tournée e le "Choral-Variationen" sul canto natalizio Vom Himme hoch..." (1955-56)
2022
The text takes up in organic form the speeches held on June 3, 2021 as part of the conference "Stravinsky in/and Italy. Day dedicated to the memory of Igor Stravinsky in the fiftieth anniversary of his death (1971-2021)" and the subsequent round table. The first paragraphs have the character of a reconstruction of the life of Igor Stravinsky ‘as an old man’, dealing above all with the theme of the trips to Italy made by the Maestro together with his wife Vera de Bosset, the conductor Robert Craft. The second part of the text is about the "Choral-Variationen on the Christmas carol “Vom Himmel hoch...”, written in 1955-56 to be performed with the Canticum Sacrum in the St. Mark’s Basilica in …
Interaction between biotin lipids and streptavidin in monolayers: formation of oriented two-dimensional protein domains induced by surface recognitio…
1989
Highly specific ligand-receptor interactions generally characterize surface recognition reactions. Such processes can be simulated by streptavidin-biotin-specific binding. Biotin lipids have thus been synthesized, and their interaction with streptavidin (or avidin) at the air-water interface was directly shown by measurement of surface pressure isotherms and fluorescence microscopy. These proteins interact with the biotin lipid monolayer via specific binding or nonspecific adsorption. Both phenomena were clearly distinguished by use of the inactivated form of streptavidin. The binding of fluorescein-labeled streptavidin to monolayers was also directly observed by fluorescence microscopy. Th…
Le poids imputable à l’exposition au stress au travail en termes économiques et de santé publique : enjeux et écueils méthodologiques
2012
L’estimation de l’effet du stress au travail sur le nombre de cas de pathologies (morbidite et mortalite) et les couts economiques associes constitue un reel enjeu de sante publique. Pourtant les etudes qui portent sur ce sujet sont peu nombreuses dans la litterature. L’objectif de l’article est de souligner l’interet d’un tel chiffrage, de presenter brievement une methode d’estimation envisageable, celle des fractions attribuables, et les difficultes methodologiques qui lui sont associees. Cette methode utilise des donnees epidemiologiques de risque relatif associe a un facteur de risque donne, et de prevalence d’exposition a ce facteur. Les difficultes methodologiques soulevees par l’util…

“Celtic migrations”: Fact or fiction? Strontium and oxygen isotope analysis of the Czech cemeteries of Radovesice and Kutná Hora in Bohemia
2014
Strontium and oxygen isotope analysis of human remains from the early La Tene (fourth/third century BC) Czech cemeteries of Radovesice I (RAD I), Radovesice II (RAD II), and Kutna Hora were conducted to investigate the importance of residential changes during the period of the historic “Celtic migrations”. In the initial phases (LT A/B), the grave goods of these cemeteries are typical for the core area of the La Tene culture, while around 300 BC (LT B2) an alteration occurs and typical Bohemian styles arise, and connections to Moravia and the Danubian region become visible. The strontium isotope ratios are highly varied with 87Sr/86Sr values between 0.7062 and 0.7153 in Radovesice, and betw…
A comparative study of the surface and bulk properties of lanthanum-strontium-manganese oxides La1âxSrxMnO3±δ as a function of Sr-content, oxygen…
1999
Abstract The properties of the perovskite-type La 1− x Sr x MnO 3± δ oxides (0≤ x ≤1) are related to the reversible redox reaction of manganese ions Mn 3+ ↔Mn 4+ . This reaction plays an essential role both in the interfacial transfers and transport properties and depends on relative cation concentrations and experimental conditions. In this paper we present experimental investigations aiming to determine, to compare and to control some of the surface and bulk properties of these oxides. The bulk and surface Mn 4+ contents were investigated by thermogravimetry analysis (TGA) in hydrogen and X-ray photo-electron spectroscopy (XPS) respectively. With a finely divided La 0.8 Sr 0.2 MnO 3 powde…

The Organizational Climate for Sustainable Commuting: An Italian Validation Study in the Academic Sector
2021
Promoting sustainable commuting represents a valuable contribution to tackle the climate crisis, and organizations could act as frontrunners in this regard. Accordingly, conceptualizing and measuring how organizational environments contribute to sustainable commuting has become relevant. This study aims to conceptualize and operationalize the construct of Organizational Climate for Sustainable Commuting (OCSC) and validate the OCSC scale in the Italian language. Data were gathered in an Italian university from 8542 participants. The validation was based on EFA and CFA, reliability, and aggregation indices analyses. To validate the scale, convergent, discriminant, internal construct, and cri…
Structure finding in cosmological simulations: the state of affairs
2013
The ever increasing size and complexity of data coming from simulations of cosmic structure formation demands equally sophisticated tools for their analysis. During the past decade, the art of object finding in these simulations has hence developed into an important discipline itself. A multitude of codes based upon a huge variety of methods and techniques have been spawned yet the question remained as to whether or not they will provide the same (physical) information about the structures of interest. Here we summarize and extent previous work of the "halo finder comparison project": we investigate in detail the (possible) origin of any deviations across finders. To this extent we decipher…
Sicily’s fold–thrust belt and slab roll-back: the SI.RI.PRO. seismic crustal transect
2016
Sicily is a thick orogenic wedge formed by (1) the foreland (African) and its Sicilian orogen and (2) the thick-skinned, Calabrian–Peloritani wedge. The crust under central Sicily, from the Tyrrhenian margin to the coastline of the Sicily Channel, has been investigated by the multidisciplinary (SI.RI.PRO.) research project. The project dealt with the nature and thickness of the crust and depth and geometry of the Moho, which is essential in formulating subduction models and improving the knowledge of African and Tyrrhenian–European lithospheres. The results resolve features such as (1) the main orogenic wedge, (2) the very steep, NW–SE-trending regional monocline suggesting inflection of th…
