Solapamiento del nicho trófico en un área de cría en la costa portuguesa
2002
The diets and the trophic niche overlap between seven flatfish species were studied in a coastal nursery adjoining to the Tagus estuary (Portugal). Fish were sampled monthly, from March to November 1999, using a beach seine. Arnoglossus imperialis (Rafinesque, 1810), Arnoglossus laterna (Walbaum, 1792) and Arnoglossus thori Kyle, 1913, fed mainly on crustaceans. The diets of Buglossidium luteum (Risso, 1810) and Dicologoglossa cuneata (Moreau, 1881) were mainly composed of Bivalvia and Polychaeta, while for Scophthalmus rhombus (Linnaeus, 1758) the main food items were Mysidacea and Teleostei. The diet of Pegusa lascaris (Risso, 1810) was mainly composed by Cumacea, Bivalvia, Decapoda and A…
ECO-FRIENDLY MATERIALS FOR THE ENERGY RETROFIT OF EXISTING BUILDINGS
2015
Today is widely recognized that the main cause of CO2 production and of non-renewable energy consumptions in Europe is due to the building field. For this reason, to improve the energy performance of existing houses through an energy retrofit action (adapting their performances to those required by regulations) is an important strategy to reduce energy consumptions since they are much more than new ones, also representing an economic opportunity. In particular, an important approach in the reducing energy needs consists in the thermal insulation of the envelope, through the application of innovative technologies and materials. The paper will present the result of a research about the possib…
TECNICHE OTTICHE PER IL MONITORAGGIO DEI CORSI D’ACQUA: UNA PROCEDURA AUTOMATICA PER L’INDIVIDUAZIONE DELLA MIGLORE SEQUENZA VIDEO DA PROCESSARE CON …
Misurare con accuratezza le portate di un corso d’acqua è uno dei principali obiettivi dell’idrometria tecnica (Eltner et al., 2020) e rappresenta da decenni una vera e propria sfida per la comunità scientifica. Le osservazioni di deflusso nei corsi d’acqua sono di fondamentale importanza per qualsiasi applicazione idrologica e idraulica (Pizarro et al., 2020) e consentono di comprendere al meglio le dinamiche di processi complessi, come ad esempio le piene lampo (Perks et al., 2016). La portata è una grandezza fisica la cui stima è caratterizzata da considerevole incertezza. Gli approcci tradizionali prevedono una stima indiretta della grandezza, attraverso un metodo velocità-area, che con…

Hierarchical-ACA DBEM for Anisotropic Three-Dimensional Time-Harmonic Fracture Mechanics
2012
A hierarchical BEM solver for the analysis of three-dimensional anisotropic time-harmonic fracture mechanics problems is presented. A thorough investigation on the relations and interactions between the numerically computed anisotropic fundamental solutions and the algorithm used to approximate the blocks of the hierarchical matrix, namely Adaptive Cross Approximation, is carried out leading to the employed computational strategy. The use of the hierarchical matrices and iterative solvers is proved as an effective technique for speeding up the solution procedure and reducing the required memory storage in time-harmonic three-dimensional anisotropic fracture mechanics problems.

Exploiting historical rainfall and landslide data in a spatial database for the derivation of critical rainfall thresholds
2017
Critical rainfall thresholds for landslides are powerful tools for preventing landslide hazard. The thresholds are commonly estimated empirically starting from rainfall events that triggered landslides in the past. The creation of the appropriate rainfall–landslide database is one of the main efforts in this approach. In fact, an accurate agreement between the landslide and rainfall information, in terms of location and timing, is essential in order to correctly estimate the rainfall–landslide relationships. A further issue is taking into account the average moisture conditions prior the triggering event, which reasonably may be crucial in determining the sufficient amount of precipitation.…
Autorità amministrative indipendenti e controllo di costituzionalità: considerazioni a partire dalla sentenza n. 13 del 2019 della Corte costituziona…
2020
The Italian Constitutional Court has been asked to decide on a constitutional incidental question referred to it by the Antitrust Authority. Rejecting the thesis of a quasi-judicial nature of the functions exercised by the Agcm and denying the existence of "gray areas" of constitutional justice, the the judgment no.13/2019 takes a position on the institutional placement of the Authorities within the administration. This, in addition to offering elements for reflections on the constitutional model of reference, requires important legal repercussions in terms of the effectiveness of the constitutional protection of connsidered interests.
Antonio Belguardo. Un maestro nella Palermo tra XV e XVI secolo: il regesto documentario
2016
Le informazioni documentarie emerse in questi ultimi anni sulla figura di Antonio Belguardo permettono di tracciare con maggiore compiutezza il profilo biografico e la parabola professionale di uno dei più prolifici protagonisti della stagione tardogotica dell’architettura siciliana; la sua attività, per quanto sinora noto, si concentra prevalentemente a Palermo tra l’ultimo quarto del XV secolo e i primi decenni del XVI. New documents that have come to light on Antonio Belguardo allow us to draw a more complete biographic profile of one of the most prolific protagonists of Late Gothic Sicilian architecture; His activity, as far as we know, was mainly carried out in Palermo, between the las…
