Cultural Heritage Preservation

This paper presents the urban vulnerability assessment as a complementary resource in heritage preservation policies, through the analysis of the thirty-nine medium-sized cities that have been listed as Historical Ensemble in Andalusia (Spain). The research seeks to make a sequential approach that addresses, from the general –the conceptual framework on urban vulnerability and the characterization of the analysis sample– to the particular  –the analysis of the socio-economic, socio-demographic or residential vulnerability applied to the intermediate scale which has not been in-deep studied yet–. For this, it proposes to adopt the methodology implemented by the Spanish Ministry of Development in the Atlas of Urban Vulnerability, providing a territorial lecture of the results. The study concludes that medium-sized cities do not present a level of vulnerability lower to the largest ones but detecting specific urban weaknesses that should be addressed to improve the response of these cities to heritage preservation.

Conservation Interventions

In the cultural heritage preservation of medieval buildings, it is common to find plaster walls covered in lime, which previously were painted in polychromy. The conservation interventions usually try to remove the whitewash, whilst maintaining the original color of the painted wall as much as possible. However, there is no agreement on which cleaning technique best preserves the original appearance of the colored plaster. Different pigments found below the lime layer may behave differently depending on the cleaning technique used. Usually, colorimetric or photometric area-based measurements are carried out to study the color of the cleaned areas to compare with their original color, obtained from pre-made plaster probes. However, this methodology fails when the mean color difference is not enough to fully characterize the changes in texture and color appearance. This study presents a set of experiments carried out using two different pigments (cinnabar and malachite) covered with lime, and treated with nine different cleaning techniques on plaster probes prepared according to medieval techniques. We have studied the effect of the cleaning process on the color and the homogeneity of the samples using a hyperspectral imaging workflow. Four different analysis methods are presented and discussed. Our results show that the proposed analysis is able to provide a much more comprehensive and diversified characterization of the quality of the cleaning method compared to the commonly used colorimetric or photometric area-based measurements.

Abstract Since the 1980s, research and qualification activities are being carried out at the 60Co gamma Calliope plant, a pool-type irradiation facility located at the Research Centre ENEA-Casaccia (Rome, Italy). The Calliope facility is deeply involved in radiation processing research and on the evaluation and characterization of the effects induced by gamma radiation on materials for different applications (crystals, glasses, optical fibres, polymers and biological systems) and on devices to be used in hostile radiation environment such as nuclear plants, aerospace and high energy physics experiments. All the activities are carried out in the framework of international projects and collaboration with industries and research institutions. In the present work, particular attention will be paid to the cultural heritage activities performed at the Calliope facility, focused on two different aspects: (a) conservation and preservation by bio-deteriogen eradication in archived materials, and (b) consolidation and protection by degraded wooden and stone porous artefacts consolidation.
