Deep-seated gravitational slope deformations in western Sicily: Controlling factors, triggering mechanisms, and morphoevolutionary models

2014

Abstract A study of deep-seated gravitational slope deformation (DSGSD) phenomena affecting areas of various geological and geomorphological settings in western Sicily is described. Western Sicily is underlain by a thin-skinned imbricate wedge of Meso–Cenozoic carbonate and siliciclastic rocks that formed by the stacking of several thrust nappes over the Iblean foreland. Locally, the original thrust sheets are folded and cut by high-angle faults. Large areas of western Sicily now display high relief energy due to Plio-Pleistocene block-faulting and uplifting, and the Quaternary morphogenetic phases are characterised by incision, thereby triggering widespread DSGSDs. To identify controlling …

L’exemplum del Dinomenide Gelone tra memoria civica e storiografica

2015

La storia della Sicilia greca è scandita, nei suoi momenti chiave, dalla persistente presenza dell’immagine del Dinomenide Gelone. Questo lavoro analizza le valenze paradigmatiche assunte dalla sua figura nella memoria civica siracusana e nella produzione storiografica; inoltre ricostruisce le dinamiche politiche che hanno spinto i principali tiranni siracusani (da Dionisio I a Ierone II) a stabilire un confronto con Gelone. Il suo exemplum è utilizzato per legittimare azioni politiche e impegno antipunico; particolare attenzione è posta alla Biblioteca storica di Diodoro Siculo e al ruolo che in essa assume la figura del Dinomenide; in relazione a questi aspetti l’opera dell’Agirinense sem…

Tra Palermo e Solunto: insediamenti, ambiente, paesaggio, viabilità e risorse in età antica

2020

This paper describes the hinterland between Palermo and Solunto (north-western Sicily). The focus is the distribution of settlements, linked to the geomorphological context, the potential resources and the ancient route system. The analysis ranges from the Archaic to the Middle Ages, when some relevant sites – both from an economic and strategic point of view – are part of the properties of the Teutonic Order. Some important routes cross the area, both in the SW direction, towards Monte Iato, and in the SE direction, towards the area of influence of the Greek colony of Himera. The analysis is carried out using toponymy and historical cartography, associated with the few archaeological data …

Prevalence of sexually transmitted infections and enteric protozoa among homosexual men in western Sicily (south Italy)

2012

Introduction. In recent years an increase in the number of sexu- ally transmitted infections (STIs) in men who have sex with men (MSM) has been reported in different industrialised countries. Because few epidemiological data on the STIs/MSM population in Sicily are available, a survey was conducted to assess the preva- lence of STIs/enteric protozoa and risky sexual behaviours among MSM in western Sicily. Methods. In 2010, 74 MSM with median age of 30 years old, were recruited via networks. All participants to the study were interviewed by anonymous self-administered questionnaire in order to collect social/demographic information, clinic data and STI-related risky sexual behaviours. After …

Sequence stratigraphy of a mesozoic carbonate platform-to-basin system in Western sicily

2009

Abstract Sequence stratigraphic studies of the Triassic through Paleogene carbonate successions of platform, slope and basin in western Sicily (Palermo and Termini Imerese Mountains) have identified a sedimentary cyclicity mostly caused by relative oscillations of sea level. The stratigraphic successions of the Imerese and Panormide palaeogeographic domains of the southern Tethyan continental margin were studied with physical-stratigraphy and facies analysis to reconstruct the sedimentary evolution of this platform-to-basin system. The Imerese Basin is characterized by a carbonate and siliceous-calcareous succession, 1200–1400m thick, Late Triassic to Eocene in age. The strata display a typ…

Interventi su volte sottili di mattoni in foglio in Sicilia (Intervention on tiled vaults in Sicily)

2016

Recenti studi hanno confermato come la diffusione nella Sicilia occidentale delle volte sottili di mattoni in foglio (“realine”) sia avvenuta in maniera estesa dalla seconda metà del secolo XVIII ai primi decenni del Novecento, sia negli orizzontamenti e nelle scale dell'edilizia corrente, che con funzione portante e di soffittatura nelle architetture nobiliari. Per finalità di studio o professionali se ne sono analizzati i caratteri costruttivi, le costanti e le variabili, con verifiche su strutture che hanno superato indenni le prove del tempo. In laboratorio o nei cantieri sono state effettuate sperimentazioni accademiche ed interventi di recupero, con ricostruzioni parziali o totali e i…

Complete sequence, expression and evolution of two members of the hexamerin protein family during the larval development of the rice moth, Corcyra ce…

2002

Three distinct types of storage hexamerins are expressed in the "last-instar" larvae of the rice moth, Corcyra cephalonica. A cDNA expression library was constructed from fat body-RNA and screened with a polyclonal antibody raised against purified hexamerin (SP2) of Corcyra cephalonica. Two slightly different "full-length" hexamerin cDNA clones (Hex2a and Hex2b) were isolated and sequenced. Both include open reading frames of 2109 bp which are translated into polypeptides of 703 amino acids with 92.5% identity. Signal peptides of 19 amino acids are present at the N-termini. The 684 amino acids native proteins have a high content of aryl groups (17.6%). According to both the criteria for ami…

A novel cell wall protein specific to the mycelial form of Yarrowia lipolytica.

1996

A cDNA clone specifying a cell wall protein was isolated from a Yarrowia lipolytica cDNA library. The cDNA library was constructed in the expression vector lambda gt 11, with the RNA isolated from actively growing mycelial cells. The deduced amino acid sequence shows that the encoded protein contains an N-terminal hydrophobic signal peptide. We have designated this protein YWP1 for Yarrowia lipolytica cell Wall Protein. Northern hybridization identified YWP1 transcript only when Y. lipolytica was growing in the mycelial form. The encoded protein seems to be covalently bound to the glucan cell wall since it is not released from the cell walls by sodium dodecyl sulphate extraction, but it is …

The nucleotide and deduced amino acid structures of sheep and pig fetuin. Common structural features of the mammalian fetuin family

1992

This study was initiated to gain further insight into the structural features of the mammalian fetuin family. The cDNA structures of sheep and pig fetuin were determined. The cDNA insert encoding sheep (pig) fetuin comprised 1550 (1470) nucleotides, including 54 (46) nucleotides encoding a signal peptide of 18 (15) residues and 1038 (1041) nucleotides encoding the 346 (347) amino acids of the mature plasma protein. The predicted amino-terminal sequence of the mature pig fetuin was confirmed by the amino-terminal sequence of the purified protein. However, two alternative sheep amino-terminal sequences were found in fetuin purified from the plasma of a single sheep fetus; the minor product wa…
