Le flotte degli Austrias e gli scali italiani: una messa a punto
2019
Since the sixteenth century, the threat of Ottoman armies and Barbary corsairs forced Spain to gradually equip and upgrade a fleet of galleys - organized in teams - which in the "Italian" geopolitical space was headed by the domains that had a maritime projection (Kingdoms of Naples, Sicily, Sardinia) and the "connected" port of Genoa. Furthermore, new territories (the State of the Presidi, the feudal enclave of Finale) were acquired to facilitate navigation within the western Mediterranean borders and the use of Ligurian ports was negotiated with the Republic of Genoa. The maritime war in its various forms was therefore at the base of an elaborate logistic and strategic organization, which…
In-Gel Assay to Evaluate Antioxidant Enzyme Response to Silver Nitrate and Silver Nanoparticles in Marine Bivalve Tissues
2022
Silver is back in vogue today as this metal is used in the form of nanomaterials in numerous commercial products. We have developed in-gel electrophoretic techniques to measure the activity of the antioxidant enzymes catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPX), and used the same techniques in combination with HSP70 Western blot analysis to evaluate the effects of nanomolar amounts of silver nitrate and 5 nm alkane-coated silver nanoparticles in tissues of the marine bivalve Mytilus galloprovincialis (Lam.) exposed for 28 days in mesocosms. Our results showed a negligible effect for nanosilver exposure and dose-dependent effects for the nitrate form.
Experimental and numerical study of anomalous thermocapillary convection in liquid gallium
1999
Thermocapillary Marangoni convection of liquid gallium was studied experimentally and numerically. A specially designed experimental setup ensured an oxide-free surface of the liquid gallium for a very long time. The convective flow at the free surface was found to be directed opposite to both buoyancy-driven and ordinary thermocapillary convection. The anomalous direction of the thermocapillary flow was explained by the presence of a small amount of a surface-active contaminant—lead adsorbed at the free surface. Two different approaches were used to describe the observed phenomenon. First, the flow was treated as a pure thermocapillary convection with a modified dependence of the surface t…

When more is less: the fitness consequences of predators attacking more unpalatable prey when more are presented
2010
In 1879, Fritz Müller hypothesized that mimetic resemblance in which defended prey display the same warning signal would share the costs of predator education. Although Müller argued that predators would need to ingest a fixed number of prey with a given visual signal when learning to avoid unpalatable prey, this assumption lacks empirical support. We report an experiment which shows that, as the number of unpalatable prey presented to them increased, avian predators attacked higher numbers of those prey. We calculated that, when predators increase attacks, the fitness costs incurred by unpalatable prey can be substantial. This suggests that the survival benefits of mimicry could be lower t…
Bonneuil-en-France (95), Aéroport du Bourget, zone nord-ouest. Un village du haut Moyen Âge, une petite exploitation agricole gallo-romaine, une nécr…
2022
Les fouilles ont eu lieu en 2016-2017 sur une surface de près de 9 hectares. Elles faisaient suite au diagnostic de 2007 (RO : T. Capararro, Inrap) et à une première fouille réalisée en 2010 sur une surface de 1,5 hectares (RO : G. Bruley-Chabot, Inrap). Hormis quelques éléments épars du Paléolithique Moyen au Néolithique, les premières traces d'occupation remontent à l'âge du Bronze final (quelques fosses et un enclos circulaire de plus de 330 m2 ). Le Hallstatt et La Tène A sont représentés par un faible nombre de structure. Une importante nécropole date de La Tène B2-C1. Elle regroupe 42 inhumations et une probable crémation. Si les ossements sont pour la plupart très mal conservés, le m…
The Monsters of Gaul: The Implications of the Concordat of Bologna (1516) for French Episcopal Elections
2021
Questo articolo riguarda le implicazioni dell'attuazione del Concordato di Bologna (1516) per la collazione e l'elezione ai benefici concistoriali, e in particolare l'elezione dei vescovi, nel regno di Francia. Il Concordato, emanato dal Concilio Lateranense V, prevedeva le presentazioni reali di candidati all'approvazione della Santa Sede. Sostituendo la cosiddetta Pragmatica Sanzione di Bourges (1438), rappresentò uno spartiacque nell'evoluzione dell'ideologia gallicana. Infatti, poiché la Sanzione era entrata nei decreti del Concilio di Basilea, la sua abolizione richiedeva che il peso dell'autorità conciliare fosse saldamente radicato in termini canonici. Alla fine, l'eredità conciliare…
