Fetid odors in Caralluma europaea (Guss.) N.E.Br. (Apocynaceae-Asclepiadoideae): a chemical characterization
2008
Recovering bronze metallurgy from archaeological artefacts for the production of reference materials in conservation science
2007
The production of reference Cu-based alloys is the first step of an original experimental protocol to be used in the field of conservation and restoration of metal artefacts. The production of these synthetic alloys has a double value. They can be used both as suitable substitutes of unique archaeological pieces for testing new materials and methods for conservation, and as guidelines for contemporary metal production. We report on a research activity focused on the recovery of the ancient production techniques from the investigation of archaeological copper-based artefacts. The chemical, physical and metallurgical characterization of several Cu-based artefacts, found in different Italian a…
La crisi vista da un archeologo. Alcune considerazioni sulla situazione attuale dei beni culturali
2015
Il contributo esamina la situazione dell'archeologia siciliana negli anni della crisi, non solo dal punto di vista dell'assenza di adeguati finanziamenti, quanto dal punto di vista della politica di tutela e valorizzazione dei beni culturali e dell'investimento nella formazione. Il punto di svolta in negativo è individuato nella legge 40 del 2000 che abolì i ruoli tecnici nell'amministrazione dei beni culturali. Perché dai beni culturali si abbia un ritorno economico è necessario investire in maniera sinergica sul beni culturali stessi, sulle infrastrutture e sulla promozione del turismo.
L’Archeologia tra formazione e pratica: il ruolo dell’Università in Sicilia
2014
The relationship between university and political and social institutions in Sicily has undergone a deep transformation since the end of the '80s. Before that period, university, as a teaching and research structure, was deeply linked with political institutions dealing with the management and preservation of cultural heritage; these institutions, on the other hand, offered the main chances of employment for graduates in humanities and archaeology. After that period, university and politic have undertaken instead, completely different ways, especially in the field of cultural heritage, due to a different economic context and a wider ideological change. The role of the university as a place …
New trials in the consolidation of waterlogged archaeological wood with different acetone-carried products
2011
Some acetone-carried consolidants for waterlogged archaeological wood were tested in order to evaluate treatments able to save time and energy. In details, colophony (rosin), two esterified colophonies (Rosin 100® and Rosin 459®), a mixture of colophony with PEG 3400 and a vinyl acetate - vinyl versate copolymer (Vinavil 8020S®) were tested. The treatments were carried out at temperatures of 20 and 35 °C on waterlogged maritime pine, elm, oak and beech. The materials came from the archaeological Site of the ancient ships of Pisa (Tuscany, Italy) and were dated back to VII cent. BC II cent. AD. To evaluate the processes, equilibrium moisture content and dimensional stability of treated woo…
Valuing cultural heritage: the social benefits of restoring and old Arab tower
2005
Abstract Cultural heritage protection is a key issue around the world today. In this paper, the contingent valuation method has been applied to obtain the social benefits that stem from the restoration of an old Arab tower in the Valencia Region of Spain. Due to a current and past lack of protection, the remains of this historic monument are few. Therefore, 252 individuals were randomly interviewed. On conducting our study we distinguished between low, average, and high consumers of cultural goods. Our main finding is that the mean willingness to pay (WTP) is considerably higher for the second group. To give further credence to this observation both parametric and non-parametric approaches …
A methodological approach in the evaluation of the efficacy of treatments for the dimensional stabilisation of waterlogged archaeological wood
2010
Abstract The aim of the work is to set up a methodological approach to verify the effectiveness of the treatments of decayed waterlogged archaeological wood and to point out the proper thermo-hygrometric conditions for its preservation after treatment. The treatments were performed on wood samples of maritime pine (Pinus pinaster Aiton), oak (Quercus sp. caducifolia), elm (Ulmus cf. minor) and strawberry tree (Arbutus unedo L.), obtained from stems pertaining to the original vegetation found in the excavation site of the Ancient Ships in Pisa (Italy), and dated from seventh century BC to second century AD The utilised products were: Polyethylene Glycols (PEG) of various molecular weights, a…
Life after death: a physicochemical study of materials used by the ancient Maya in human bone ointments
2021
Ancient Maya believed in life after death. They used to prepare dead bodies during burial ceremonies whose purpose was to celebrate the dead and to help them passing through the way from earthly life to the beyond one. Bodies preparation included coloured scented body ointment application, with a deep symbolic connotation and probably also a conservative purpose. The aim of this research was to characterize pigments and binders used by ancient Maya in the preparation of body oint ments used to paint human bones. Emblematic painted bone samples from Xcambó (Maya archaeological site located in the municipality of Dzemul, in the Mexican state of Yucatán) were investigated through a non-destruc…
Architettura per il terzo fragile. I patrimoni di Pizzo Sella fra riuso sociale, sostenibilità civica e giustizia spaziale
2022
Il territorio palermitano è il primo in Europa per presenza di beni confiscati. I casi sono diverse migliaia e compongono una realtà emblematica rispetto ai fattori di fragilità sociali e spaziali dei ter-ritori contesi fra crimine e giustizia, in cui spicca la vicenda iconica e irrisolta di Pizzo Sella. La ricerca di cui quest’articolo restituisce alcuni risultati indaga quindi il rapporto fra la produzio-ne dell’architettura della res publica e i contesti in cui il concetto di Pubblico è in panne, in cui la diversione dalla legge e l’antagonismo esercitato da forze illegali non sono un’aberrazione tempora-nea, ma la regola, e lasciano tracce materiali sui modi di produzione delle forme co…
Special Issue “Smart Urban Lighting Systems”
2020
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, ser…
