La vegetazione del litorale di Manfria, presso Gela (Sicilia), area soggetta a vincolo archeologico.

2000

The results of a phytosociological investigation about a coastal area of S. Sicily, close to Gela, are presented. The coexistence of several lithological substrata, as well as the particular climatic conditions of this area, gives rise to a noteworthy floristic and vegetational biodiversity. As matter of fact, a set of N. African species are here localized, taking part to peculiar vegetation types, sometimes exclusive of this sicilian coast-stretch. The observed plant communities are represented by psammophilous associations of Cakiletea maritimae, Ammophiletea and Malcolmietalia, salt-marsh vegetation of Sarcocornietea and Phragmito-Magnocericetea, halophilous rupicolous shrublands of Crit…

STUDIO ETNOARCHEOMETRICO DI MALTE AEREE A LEGANTE GESSOSO NELL’AREA DELLE MADONIE (SICILIA SETTENTRIONALE)

2010

The Madonie Regional Park, which covers an area of about 400 square kilometres, is an ideal context where environment and man activities are still mixed harmoniously. In the last years a variety of ethno-archaeometric investigations have been carried out in order to study various aspects of the "material culture" of this territory. In particular, the research was focused on the production of majolica which have had a great importance since the early decades of the 16th century thanks to the geolithological features of the Madonie area, particularly rich in clayey raw material. The traditional building techniques of the Madonie which involve several typologies of building materials (used for…

La maschia potenza. Pratiche ergologiche e coreutica rituale nella civiltà contadina

2020

In occasione di diverse celebrazioni religiose che scandiscono il calendario cerimoniale siciliano, in specie nel corso della Settimana Santa e di alcune feste patronali,   possibile osservare delle modalità  di trasporto dei fercoli processionali (vare) assai peculiari. I santi simulacri, infatti, in tali circostanze, sono fatti correre e danzare sia per le strade dei centri abitati sia, in rari casi, all’interno degli edifici religiosi. Il disordine che connota queste performances coreutiche   solo apparente. Esse obbediscono in realtà  a un preciso codice cinetico: i fercoli vengono ritmicamente alzati e abbassati sulle braccia dai portatori, roteano ripetutamente su se stessi facendo id…

Probabilistic Flood Hazard Mapping Using Bivariate Analysis Based on Copulas

2017

This study presents a methodology to extract probabilistic flood hazard maps in an area subject to flood risk, taking into account uncertainties in the definition of design hydrographs. Particularly, the authors present a new method to produce probabilistic inundation and flood hazard maps in which the hydrological input (i.e., synthetic flood design event) to a 2D hydraulic model has been obtained by using a bivariate statistical analysis (copulas) to generate flood peak discharges and volumes. This study also aims to quantify the contribution of boundary conditions’ uncertainty in order to evaluate the effect of this uncertainty source on probabilistic flood hazard mapping. Different comb…

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.…

Hypogenic caves in Sicily: a preliminary study of morphological and depositional features

I.2 L’area Nord-Occidentale, in Carra et alii, Le aree funerarie fra isola e terraferma: esempi dalla Sicilia e dalla Sardegna, pp. 135-179

2015

Christian funerary evidence of Sicily and Sardinia are among the 3rd-4th century and 7th-8th. They were defined “useful fossils” to determine the incidence of the new religion in urban areas and the importance of the settlement spread over vast areas. The burial areas recognized in Sardinia are about one hundred; in Sicily they are more and more numerous; they are distributed along the route of the ancient roads and fall within the areas of competence of the diocese known by some letters of Pope Gregory the Great. They were divided into three categories: burial areas sub divo, rural and urban; burial underground areas, urban and rural; burial areas connected with a rural church or with a ma…

Outgassing of mantle fluids across an tectonically active crustal segment in between two volcanic systems (Etna and Aeolian arc): the Nebrodi-Pelorit…

2018

Mantle-degassing occurs primarily through active volcanic systems and young oceanic lithosphere. Mantle-volatiles are also released by tectonically active continental regions, but the magnitude of this phenomenon is far less characterised. Helium (He) is a powerful tracer to track deep volatile degassing, because the mantle contains more 3He than the crust/atmosphere systems, which are dominated by radiogenic 4He produced in the crust. Here, we studied the volatiles in thermal manifestations discharged along the Nebrodi- Peloritani chain in north-eastern Sicily, with the aim of investigating the origin of thermalism and the related fluids. Thisseismically active region connects the African-…

The HCV Sicily Network: A web-based model for the management of HCV chronic liver diseases

2016

Epidemiological studies report that in Sicily reside about 30,000 citizens with a diagnosis of chronic hepatitis due to HCV. The availability of direct antiviral action (DAA) is a real therapeutic breakthrough, but the high cost of the therapeutic regimes limits their use and forced the National Health System to establish clinical priority for the treatment.The HCV Sicily Network is a web-based model of best medical practice, which was designed to improve the management and the treatment of HCV chronic hepatitis and cirrhosis. The network includes 41 centers and 84 gastroenterologists or infectivologists connected by a web platform that recorder the diagnosis and the clinic priority for the…
