Partitioning between “wedge-top” river- and wave-dominated successions: an example from the late Tortonian — early Messinian Terravecchia Formation (…
2011
AbstractDetailed field sedimentological and facies analyses have been performed in the Terravecchia Formation cropping out in NW Sicily, in order to differentiate and describe, for the first time, wave- and river-dominated shallow-marine (deltaic) siliciclastic successions. The latter were deposited filling syntectonic basins, developed between the late Tortonian and early Messinian time, within the wedge-top depozone of the Sicilian Foreland Basin System. It has been observed that river-dominated successions, recording the deposition of small fan-deltas are characterized by fining- to coarsening upward, transgressive-regressive sequences which were mostly deposited filling relatively narro…
Inner vs. outer wedge-top depozone “sequences” in the Late Miocene (late Tortonian–early Messinian) Sicilian Foreland Basin System; new data from the…
2012
Abstract The wedge-top depozone belongs to the innermost portion of a Foreland Basin System (FBS) ( DeCelles and Giles, 1996 ) and includes all sediments, typically coarse-grained proximal facies, that bury the active frontal part of a fold and thrust belt. The Terravecchia Formation ( Flores, 1959 , Schmidt Di Friedberg, 1962 , Schmidt Di Friedberg, 1964 , Catalano, 1979 ) is a composite lithostratigraphic unit widespread in Sicily (southern Italy) which has been recently considered ( Gugliotta, 2010 ) as a part of the stratigraphic record of the Late Miocene (late Tortonian to early Messinian) Sicilian wedge-top depozone and represent the main object of this paper. Two end-member wedge-to…
Using high-resolution stratigraphy and structural analysis to constrain a “polyphase” tectonics in wedge-top basins. Inferences from the Late Tortoni…
2012
Abstract The present paper aims to show, both from a stratigraphic and structural points of view, the main features of a wedge-top syntectonic basin which evolved recording polyphase and non-coaxial tectonics. The study area is the Scillato Basin ( SB ), a roughly N–S-oriented structural depression located in the central-northern sector of the Sicililian Maghrebides. There, an approximately 1300 m-thick upper Serravallian to upper Tortonian succession of clastic units outcrops as a portion of the Neogene syntectonic covers of the Sicilian fold and thrust belt. Within the outcropping succession the upper Tortonian Terravecchia Fm represents the main topic of this paper. A multidisciplinary a…
Testing e validazione comparativa di coating idrofobizzanti per superfici in gelcoat
2021
Nell’industria delle telecomunicazioni a supporto del settore aerospaziale, il mantenimento dell’efficacia e della sicurezza delle trasmissioni in condizioni ambientali estreme assume un’importanza crescente, in funzione della sempre maggiore diffusione dei siti trasmittenti/riceventi, operativi su scala planetaria. In questa cornice, si richiede che gli elementi a protezione dei dispositivi installati si dimostrino durevoli nel tempo anche quando esposti ad abbondanti precipitazioni, accumuli nevosi continuati o stratificazioni di ghiaccio, e improvvisi shock termici, garantendo nel contempo la fedeltà della trasmissione. Una marcata idrofobicità degli strati esterni delle coperture risult…

MALTE INNOVATIVE PER LA COPERTURA DELLE CRESTE MURARIE IN AMBITO ARCHEOLOGICO
2014
The main objective of this study is to evaluate the opportunities offered by nanotechnologies to the production of innovative mortars with enhanced performances for the reconfiguration of walls ridges in the archaeological field. In particular, an already existing additive, based on silica nano-particles in aqueous solution, was tested mixing it in varying percentages to a hydraulic lime mortar and pozzolana. The following tests were carried out on different samples: resistance to bending and compression, adhesion to the surface, water absorption coefficient through capillarity, accelerated ageing test using salt mist. In the final stage, some comparative considerations among the different …

Allucinazioni visive tra demenza e psicosi.
2017
Le allucinazioni possono comparire in corso di varie patologie (psicosi, delirium, demenza, emicrania, neoplasia, epilessia) o possono essere altresì indotte da farmaci. Esse sono percezioni involontarie e ricorrenti di immagini in assenza di un corrispondente stimolo fisico esterno. Possono essere classificate in semplici o complesse. Si definisce allucinazione semplice quella in cui è attivata una singola modalità sensoriale e quindi la percezione non richiede un’elaborazione cognitiva per essere decodificata (ad es. vedere un oggetto in una stanza); complessa è invece l’allucinazione in cui sono attivate più modalità sensoriali (es. vedere un leone sentendo che ruggisce) o in cui la perc…
