Tritium retention measurements by accelerator mass spectrometry and full combustion of W-coated and uncoated CFC tiles from the JET divertor
2016
Abstract Accelerator mass spectrometry (AMS) and the full combustion method (FCM) followed by liquid scintillation counting were applied to quantitatively determine the tritium retention in the tungsten-coated carbon fibre composites (CFC), in comparison to uncoated CFC tiles from the JET divertor. The tiles were adjacent and exposed to plasma operations between 2007 and 2009. The tritium depth profiles are showing that the tritium retention on the W-coated tile was reduced by a factor of 13.5 in comparison to the uncoated tile whereas the bulk tritium concentration is approximately the same for both tiles.

Maiolica bricks spires and domes in Sicily.Tipology, constructive and decorative elements
2018
The use of maiolica bricks as artefact for surface decoration is widespread both in monumental and ordinary architectures in the Mediterranean regions, harmonizing the local construction traditions with the Islamic influences. This study presents an in-depth analysis of examples of spires and domes in Sicily featuring earthenware maiolica cladding serving both as decoration and structural element. Due to the limited knowledge of these artefacts, incautious construction operations led to an alteration of their material and technical features, putting at risk a centuries-old heritage. The systematic investigation on more than a hundred samples categorises these architectural polychrome elemen…

Price discrimination and market power in export markets: The case of the ceramic tile industry.
2005
This paper combines the pricing-to-market equation and the residual demand elasticity equation to measure the extent of competition in the export markets of ceramic tiles, which has been dominated by Italian and Spanish producers since the late eighties. The findings show that the tile exporters enjoyed substantial market power over the period 1988-1998, and limited evidence that the export market has become more competitive over time.
E pluribus unum. Il ruolo del pattern geometrico nella storia dell'arte siciliana
2020
The harmony of forms seems to be regulated by its own laws compatible with the cognitive processes that regulate their perception. From the mimesis of nature, artistic forms investigate the geometric relationships between the parts and define systems of representation that exploit the optical phenomenon of the tessellation to obtain complex configurations from simple polygonal modules were born. The simplest tessellation finds its first application in the mosaic whose origin as a practice is very ancient, evolving up to the Greco-Roman world enriching and differentiating itself in two essential styles, one pictorial and one abstract, both beautifully represented within the Villa Romana del …
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…
Timbrel vaults in Sicily. Constructive techniques and intervention methodologies
2017
Tra le tante tipologie di volte riscontrate sul territorio siciliano finalizzate a coniugare economia e leggerezza senza perdere in sicurezza, vengono in questo studio analizzate quelle costituite da due, tre o quattro fogli di mattoni sottili uniti con gesso (volte realine secondo la definizione locale). Non si hanno notizie certe sull’origine di queste volte che, probabilmente introdotte dall’area iberica in Sicilia nella prima metà del XVIII secolo, evidenziano come un sistema costruttivo importato da aree geografiche spesso molto distanti possa essere reinterpretato in funzione dei materiali disponibili e della cultura edilizia locale. Ciò ha in più occasioni determinato soluzioni origi…
How does diversity affect district innovation systems?Findings from a comparative study of european ceramics
2018
This research applies Nelson’s (1993) primary typology of enterprises to understand why the propensity for innovation varies across ceramics district innovation systems in Europe. We use innovation systems and industrial district theories to explore the innovation capacity of the two most important ceramic tile industrial districts in Europe—Emilia Romagna in Italy and Castellon in Spain. Our analysis shows that, in both districts, innovation plays a decisive role in allowing companies to maintain competitiveness in a globalizing market. However, by comparing the composition of their district innovation systems, our analysis shows that: (i) although levels of competition in both districts a…
