Wave Energy Assessment along Sicilian Coastline, Based on DEIM Point Absorber
2017
The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around the island. A point absorber is present in order to exploit this source. Two scenarios are presented, with two different levels of energy production.
Fortifying the Island at the time of the viceroy Ferrante Gonzaga (1536-1546): sites, master builders and designers, clients
2015
Abstract The ten-year government of Ferrante Gonzaga marks a crucial time in the process of modernization of fortifications on the largest island of the Western Mediterranean. Even if the cornerstones of the strategy pursued and the projects undertaken to realize an adequate defense system have already been highlighted by previous studies, and it is well-known how much the viceroy himself and the royal engineer Antonio Ferramolino participated in resolving the longstanding problem, new interesting data emerge from research on the archival collections of Tribunale del Real Patrimonio, kept in the State Archive of Palermo. Using this mostly unpublished documentation, the paper focus on buildi…
Integrating thermal and mechanical characteristics of historic masonry categories: Development of a Sicilian database
2021
Detailed construction analysis is essential to the compatible energy improvement of historic buildings. In-situ measurements are crucial for energy diagnosis but their use is limited, especially in vernacular architecture. This paper exposes the development of a hygrothermal and mechanical database for Sicilian historic walls. The proposed method, applied to eleven historic centres, is based on the investigation of those masonry construction features, which recur in local contexts. Preliminary results concern the case study of Petralia Sottana, where a first set of laboratory measurements of stone compressive strength and thermal conductivity was conducted, together with in-situ tests of ma…
The Bell-Tower Facade: An Aseismic Device in Sicily Between the 12th and 18th Centuries
2014
Imposing tower facades with belfries in the last order were built in Sicily Italy, from the Middle Ages to the late Baroque period. Until the 16th century, this model, which was inspired by northern European examples, also had a parallelepiped forepart leaning against the facade, working as containment for the pressure imparted by the inner longitudinal arches on the front, and amplified in case of earthquakes. The lacking static efficiency of these early structures is demonstrated by collapses during the strong earthquakes that hit the island in the modern age. Despite numerous cases of destruction, the memory of some prototypes survived in Sicilian constructive memory through the elaborat…
The Area Of The Strait Reading Theories And Strategies For A Metropolitan Dimension
2016
Abstract Extending across a peninsular strip going from Gioia Tauro to Melito Porto Salvo on the Calabrian side, and from Milazzo to Giardini Naxos on the Sicilian side, the Strait of Sicily sees theAspromonte massif and the Peloritani mountain range as two facing stage sets of land sketching in the gulf a water piazza of a landscaping room. Described in the proposal by Giuseppe and Alberto Samona, Ludovico Quaroni, Antonio Quistelli, Sergio Musmeci, Paolo D’Orsi Villani and Leonardo Urbani, it outlines, in the county seats of Reggio Calabria and Messina, the prevalence of a Euclidean space, identifiable in the exact metrics given by the recurrence of the measuring step of the blocks drawn …
Inferring Population Structure from Early Life Stage: The Case of the European Anchovy in the Sicilian and Maltese Shelves
2022
The European anchovy is an important fishing resource in the Sicilian Channel that supports a high recruitment success variability. The presence of two spawning areas, the drifting of the larvae along the currents and the different oceanographic conditions within the region suggest the presence of different larvae subpopulations. Morphometric and biochemical approaches have been used to analyze the differences among larvae collected. The amino acid composition discriminates two larval groups closely related to the spawning regions: Adventure Bank and the shelf between the South of Sicily and Malta. In addition, there are morphometric and growth differences between recently hatched larvae in…
Enti pubblici economici, società ad evidenza pubblica e privatizzazioni nell’ordinamento della Regione siciliana
2017
Con questo contributo si intendono ripercorre le alterne vicende dell’intervento della Regione siciliana in economia attraverso enti e società e, più recentemente,mediante fondazioni di partecipazione, consorzi ed organismi associativi. La Regione siciliana è stata ed è ancora, tra corsi e ricorsi, una Regione imprenditrice.
Tre note di epigrafia cristiana in Sicilia
2014
Si presentano tre interessanti studi di epigrafia cristiana siciliana. Il primo, attraverso l’analisi dei sostantivi ἐκκλησία/ ecclesia riscontrati in 18 documenti epigrafici siciliani, proietta la Sicilia nel più ampio panorama mediterraneo e contribuisce alla integrazione della cronotassi episcopale di Siracusa e Catania nel periodo compreso tra il IV e il VII secolo, con qualche attardamento ai secoli VIII-IX. Il secondo studio riguarda il sigillo del vescovo Felix panormitanus, rinvenuto nel territorio di Carini (Palermo) e finora inedito. Si tratta di un’interessante testimonianza archeologica utile a integrare la storia delle relazioni fra le limitrofe diocesi di Carini e Palermo alla…
Genetic and phytochemical difference between some Indian and Italian plants of Whitania somnifera (L.) Dunal
2007
The geographical distribution of Withania somnifera (L.) Dunal is quite wide. However, in Italy. this species is very rare and grows spontaneously only in Sicily and in Sardinia. The PCR-RAPD technique has been utilized in this work to determine the genetic relationship among Sicilian, Sardinian and Indian samples and the HPLC analysis of whitaferin A was used as a marker to evaluate the phytochemical differences. The genetic difference between Indian and Sicilian plants of W. somnifera turned out to be smaller than that between Indian and Sardinian plants of this species. The phytochemical analysis as well showed that the Sardinian specimen strongly differed from the Indian and Sicilian on…
