Sulla distribuzione di alcuni Uccelli nidificanti in provincia di Trapani (Sicilia)
2019
A distanza di 10 anni dalla pubblicazione dell’ultimo Atlante dei Vertebrati di Sicilia si rivede la distribuzione delle specie nidificanti, alla luce di nuovi dati raccolti, al fine di aggiornare il loro status. Nel presente lavoro vengono elencate solo le specie di uccelli, rilevate in questi ultimi anni, non segnalate come nidificanti nei precedenti Atlanti e le specie già trattate ma che hanno riportato delle variazioni significative nella loro distribuzione. Updating of the distribution of some breeding birds in the province of Trapani (Sicily). This work deals with the distribution of the breeding birds in the province of Trapani (western Sicily); here are provided and updated the sta…
The role of the diagnostic areas in the assessment of landslide susceptibility models: a test in the sicilian chain
2011
Abstract The aim of the research was to verify and compare the predictive power of different diagnostic areas in assessing landslide susceptibility with a multivariate approach. Scarps, landslide areas (the union between scarp and accumulation zones) and areas uphill from crowns, for rotational slides, source or scarp areas and landslide areas, for flows, have been tested. A multivariate approach was applied to assess the landslide susceptibility on the basis of three selected conditioning factors (lithology, slope angle, and topographic wetness index), which were combined in a Unique Condition Unit (UCU) layer. By intersecting the UCU layer with the vector layer of the diagnostic areas, la…
Active faulting and continental slope instability in the Gulf of Patti (Tyrrhenian side of NE Sicily, Italy): a field, marine and seismological joint…
2016
The Gulf of Patti and its onshore sector represent one of the most seismically active regions of the Italian Peninsula. Over the period 1984–2014, about 1800 earthquakes with small-to-moderate magnitude and a maximum hypocentral depth of 40 km occurred in this area. Historical catalogues reveal that the same area was affected by several strong earthquakes such as the Mw = 6.1 event in April 1978 and the Mw = 6.2 one in March 1786 which have caused severe damages in the surrounding localities. The main seismotectonic feature affecting this area is represented by a NNW–SSE trending right-lateral strike-slip fault system called ‘‘Aeolian–Tindari–Letojanni’’ (ATLFS) which has been interpreted a…
Evidence of positive tectonic inversion in the north-central sector of the Sicily Channel (Central Mediterranean)
2016
In order to unravel the tectonic evolution of the north-central sector of the Sicily Channel (Central Mediterranean), a seismo-stratigraphic analysis of single- and multi-channel seismic reflection profiles has been carried out. This allowed to identify, between 20 and 50 km offshore the central-southern coast of Sicily, a ~80-km-long deformation belt, characterized by a set of WNW–ESE to NW–SE fault segments showing a poly-phasic activity. Within this belt, we observed: i) Miocene normal faults reactivated during Zanclean–Piacenzian time by dextral strike-slip motion, as a consequence of the Africa–Europe convergence; ii) releasing and restraining bend geometries forming well-developed pul…
Atmospheric CO2 Concentrations in Caves Protected as Nature Reserves and Related Gas Hazard
2022
Atmospheric CO2 concentrations can reach high levels inside natural caves, representing a hazardous condition for both humans frequenting the underground environment and its safeguard due to the corrosion of speleothems induced by the acidification of atmospheric moisture. These issues are particularly critical for the eco-sustainable management of caves protected as nature reserves and undergoing touristic exploitation. In this paper we present the results of the C6 project, which was activated in 1999 for the monitoring of air quality inside three caves protected as nature reserves in Sicily (Italy). Near-real-time and spot measurements of air temperature and CO2 concentration have been c…
Modi di abitare, tipi e varianti: alcune riflessioni sulla cultura abitativa ellenistico-romana in Sicilia
2020
After a brief survey on the previous studies on the Sicilian domestic architecture of the hellenistic and Roman periods, this paper questions the idea of a continuous development of the Greek house's central space, from the simple court to the peristyle, as well as the opposition between “centripetal”and “axial” (i.e. the Greek peristyle house and the Roman atrium house). This rigid distinction doesn't take in account the existence of an hybrid form of the court that doesn't fit well in these comfortable cathegories: the “tetrastylon”. Sicilian houses are reconsidered in order to establish if this and other single houses' features can be labelled as “Punic”, “Greek” or “Roman” or if this is…
Attitudes, behaviours and perceptions of Italian General Practitioner trainees towards influenza vaccination in Western Sicily (Italy)
2012
Background: General practitioners (GPs) have to be considered as key figures of health promotion among health care workers since they are strongly asked to recommend influenza vaccination to their patients and perform on them. Despite this consideration, GPs have influenza vaccination rates that are significantly below the 75% coverage proposed by International Public Health guidelines. In order to increase future coverage of influenza vaccination within GPs, and through them within the population, the aim of this study was to assess determinants associated with influenza vaccine uptake among GP trainees. Methods: A survey was carried out on GP trainees attending the training course in Comm…
Immagini ed echi di Augusto in Sicilia: realia e contesti, res incertae vel alienae
2022
The paper gathers and analyzes the data useful for reconstructing the reception and the legacy of Augustus’ image in Sicilian civic contexts. Beside the four portrait heads from Syracuse, Centuripe, Tyndaris, Taormina, several sculptural, epigraphic and numismatic testimonia are considered from the above-quoted cities and other Sicilian sites. Except for few more ancient inscriptions/statues(?) (Syracuse) and coins (Segesta), a key moment in the response by the local civic communities to the imperial model is around Augustus’ visit of 21 B.C. and in the immediate period after his death. Moreover, a series of testimonia, mainly inscriptions and coins, belong to mid(-late) Augustan age, parti…
Differenziazione e quantificazione dei carbonati litogenici e pedogenici di Gypsisuoli forestali attraverso l'analisi isotopica
2004
Gli autori riferiscono sui tipi e sui modelli di genesi dei carbonati dei suoli, attraverso l’uso degli isotopi del 13C. Lo studio è stato condotto in un’area dell’interno collinare argilloso siciliano, su suoli che evolvono sui depositi evaporitici della Serie Gessoso-Solfifera. Sono stati scelti cinque pedon su litotipi calcarei e non. I pedon sono stati descritti in campo e campionati secondo la sequenza degli orizzonti genetici; sui campioni di suolo sono state eseguite le seguenti analisi: tessitura, reazione, conducibilità elettrica, gesso, carbonio organico ed inorganico. Inoltre, parallelamente sono state eseguite le analisi isotopiche del carbonio organico ed inorganico. I risultat…
