Comunicare il restauro

2017

The crisis in values and the political-economic problems that plague modern-day society affect, among other things, the topic of architectural heritage protection and enhancement. Given its role as a historic trace of thousand-year-old civilisations, cultural heritage has often been liable to exploitation for religious, political as well as cultural purposes. For this reason, traditional conservation instruments are inadequate if we want to tackle modern-day circumstances, and those who work in the field of conservation should now play an important role not only in the concrete protection of this heritage (through conservation, maintenance, reuse and so on), but also in finding new cultural…

Environmental effects of energy policy in sicily: The role of renewable energy

2007

The saving of primary energy from fossil fuels and the promotion of exploitation of renewable sources are two of the most relevant goals to be achieved in order to match the climate protection target fixed by the Kyoto Protocol in 1997. For Italy, the commitment is the reduction of the greenhouse emissions by 6.5% below 1990 levels over the commitment period 2008–2012. It requires the introduction of suitable political strategies and programmes aimed to establish a sustainable energy system together with the application of a set of actions either at national scale, either at regional one. This study presents the results of a survey in the context of the Regione Sicilia about the potential s…

An empirical approach for ranking environmental and energy saving measures in the hotel sector

2009

The energy demand of the hotel sector of an Italian region is here utilized for hierarchizing, by means of an empirical method, efficient measures devoted to energy saving and reduction of CO2 emissions. Due to the large number of consumers present in the selected territorial area and the lack in detailed data, the energy demand assessment is here carried out by the analysis of a sample of representative consumers. A short set of indexes, referring to energy and environmental performances, are defined and calculated for different clusters of hotels, grouped on the basis of site characteristics, opening periods, number of beds, and building age. Such indexes are utilized to establish lists o…

A model for predicting the potential diffusion of solar energy systems in complex urban environments

2011

Abstract The necessity to reduce greenhouse gases emission produced by energy building consumptions and to cut the energy bill (mainly due to the use of fossil sources) leads to the employment of renewable energy sources in new planned scenarios. In particular, more and more often municipal energy and environmental plans pay great attention to the possibilities of employment of the solar technologies at urban scale. Solar thermal and photovoltaic (PV) systems are, by far, the most suitable tools to be utilized in urban areas. Obviously, the proper adoption of such systems in buildings does call for the availability of calculation methods suitable to provide the actual level of exploitation …

Polymer-coated Nanolimes Dispersions for Reduction, Deacidification and Consolidation of Ancient Paper

Nanolimes have been widely explored as nanomaterial for cultural heritage preservation. In particular, they have shown interesting properties to contrast the ageing of manuscripts, books and artistic works, opening up the possibility to store such items in a good quality state for longer. In the present work we reported an innovative nanolime-based formulation for paper restoration, which includes in its composition a reducing agent and a fibers consolidator as well. To formulate an efficient product, we deeply investigated the cellulose oxidation process with a multi-technique approach. The here presented formulation consists in a hydroalcoholic ternary dispersion of nanolimes coated with …

An Adaptive Bayesian System for Context-Aware Data Fusion in Smart Environments

2017

The adoption of multi-sensor data fusion techniques is essential to effectively merge and analyze heterogeneous data collected by multiple sensors, pervasively deployed in a smart environment. Existing literature leverages contextual information in the fusion process, to increase the accuracy of inference and hence decision making in a dynamically changing environment. In this paper, we propose a context-aware, self-optimizing, adaptive system for sensor data fusion, based on a three-tier architecture. Heterogeneous data collected by sensors at the lowest tier are combined by a dynamic Bayesian network at the intermediate tier, which also integrates contextual information to refine the infe…

Obsidian from the Neolithic Layers of “Grotta di San Michele Arcangelo di Saracena” (Cosenza), Italy. A Preliminary Report

2021

Abstract The paper presents the results obtained by techno-typological analysis of a lithic assemblage from the Neolithic layers of Grotta San Michele Arcangelo di Saracena (Cosenza) together with the results of micro-wear analysis obtained from a preliminary selection of obsidian artifacts with different provenances distinguished by pXRF analysis. The site provides one of the best preserved Neolithic sequences in the area, from the earliest Impressed Wares (or Impresse Arcaiche) (early sixth millennium BC) to the Spatarella pottery style (end fifth – early fourth millennium BC). Along the Neolithic sequence, it is possible to observe some major changes within lithic resources management. I…

«Una vera e non museografica conversazione di monumenti e di ambienti»: Guido Di Stefano e l’«azione urbanistica» nella Palermo del secondo dopoguerra

2019

L' articolo indaga gli scritti, le attività didattiche e le reti culturali dell'arte e dell'architettura siciliana storico Guido Di Stefano (1906-62). Concentrandosi sui suoi viaggi in Germania e sui suoi contatti con colleghi austriaci (Dagobert Frey), tedeschi (Wolfgang Krönig) ed eminenti colleghi italiani (Carlo Ludovico Ragghianti), l'autore legge la battaglia solitaria di Di Stefano contro la speculazione e il vandalismo nel settore immobiliare a Palermo, nonché il suo coinvolgimento nel stesura del piano urbano dopo la seconda guerra mondiale come aspetti specifici di un'idea di civiltà e impegno politico le cui radici possono essere identificate nell'influente pensiero filosofico di…

Museomics Provides Insights into Conservation and Education:The Instance of an African Lion Specimen from the Museum of Zoology “Pietro Doderlein”

2023

Innovative technological approaches are crucial to enhance naturalistic museum collections and develop information repositories of relevant interest to science, such as threatened animal taxa. In this context, museomics is an emerging discipline that provides a novel approach to the enhancement and exploitation of these collections. In the present study, the discovery of a neglected lion skeleton in the Museum of Zoology “Pietro Doderlein” of the University of Palermo (Italy) offered the opportunity to undertake a multidisciplinary project. The aims of the study consisted of the following: (i) adding useful information for museographic strategies, (ii) obtaining a new genetic data repositor…
