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…
L'avventurina nei gioielli siciliani tra Seicento e Ottocento
2021
The aventurine glass between the seventeenth and nineteenth centuries was much appreciated by Sicilian women, aristocrats, bourgeois but also commoners, especially for its characteristic color
Un ripostiglio inedito dall’insediamento di Balate di Marianopoli (Caltanissetta)
2012
The subject of the contribution is a small hoard of 38 coins discovered during the excavations of 1986 in the anellenic center of Balate di Marianopoli (CL). The study examines the composition of the hoard, which also includes a rare specimen with the signature of the engraver Kimon, specifying the date of burial on the basis of the contextual material and proposing a historical interpretation
A new historical perspective regarding the baptismal font of the cathedral of Monreale (Sicily): the identification of a reused Roman labrum by an an…
2017
The Cathedral of Monreale (not far from the city of Palermo) is one of the most famous monuments of the Arab-Norman period in Sicily recently added to the World Heritage list by UNESCO. It is well known above all for its structure and the magnificence mosaic decorations inside. In the church it is also conserved a Baptismal Font made of coloured limestone and dated back to the first decade of the 17th century. The present study deals with this valuable object with the aim of obtaining information about the nature and provenance of the coloured limestone constituting the basin. Laboratory analyses were thus carried out on representative stone samples by means of polarized light microscopy as…
Geochemical constraints on basalt petrogenesis in the Strait of Sicily Rift Zone (Italy): Insights into the importance of short lengthscale mantle he…
2020
Igneous activity from the late Miocene to historic time (most recently 1891 CE) in the Strait of Sicily has created two volcanic islands (Pantelleria and Linosa) and several seamounts. These volcanoes are dominated by transitional (ol + hy-normative) to alkaline (ne-normative) basaltic lavas and scoriae; volcanic felsic rocks (peralkaline trachyte-rhyolite) crop out only on Pantelleria. Although most likely erupted through continental crust, basalts demonstrate no evidence of crustal contamination and are geochemically similar to oceanic island basalts (OIB). Despite their isotopic similarities, there are considerable compositional differences with respect to major and trace element geochem…
New stratigraphical data on the Middle-Late Jurassic biosiliceous sediments from the Sicanian basin, Western Sicily (Italy)
2008
The reported data present the stratigraphy of several sections across a Middle–Late Jurassic Radiolaritic Unit, well exposed in different thrust sheets pertaining to the Maghrebian chain of Southwestern Sicily. The aim was to define the chronostratigraphical distribution of the Jurassic biosiliceous sedi- mentation in the Sicanian palaeogeographical zone, a deep water basin belonging to the Southern Tethys continental margin. The radiolarian biostratigraphy indicates that the switching from carbonate to siliceous sedimentation in the Sicanian Basin is referable to the Bajocian, as shown by the section of Campofiorito, near Corleone. The biostratigraphical dataset allows the correlation betw…
