Vegetation changes and human action from the Neolithic to the Bronze Age (7000?4000 B.P.) in Alicante, Spain, based on charcoal analysis
1994
Charcoal analysis reveals various palaeo-ecological phases from the Neolithic to the Bronze Age. Agriculture starts about 7000 B.P. in favourable ecological conditions. Most of the charcoal spectra from sites on the coast represent thermomediterranean holm-oak forest; those from the inland mountains represent mesome-diterranean holm-oak forest. The Neolithic I Impressed Ware people were the first to clear the forest to plant their crops. This clearance of primary woodland resulted in the development of secondary vegetation of pine woods or scrub. The scrub reached its maximum during the Bell Beaker phase and Bronze Age in the Cova de les Cendres. In the Neolithic II open air sites, the perc…
Mid-Holocene vegetation dynamics in the Tejo River estuary based on palaeobotanical records from Ponta da Passadeira (Barreiro-Setúbal, Portugal)
2014
This paper presents the results of pollen and charcoal analyses carried out in the sedimentary formation of Ponta da Passadeira, south of the Tejo River estuary, Portugal. The data provide information regarding the evolution of the coastline and ecosystem of the estuary during the mid and late Holocene. The study focuses on a group of upright woody fossilized tree remains that, together with those identified earlier by Garcia-Amorena et al. (2007), form part of the fossil forest of Ponta da Passadeira. Eight remains were identified as Pinus pinaster, four as Pinus pinea and one as Pinus sp. Two specimens of these species were dated to 6523 and 5805 cal. a BP. Pollen analysis was undertaken …
Non-Invasive Investigation of Pigments of Wall Painting in S. Maria Delle Palate di Tusa (Messina, Italy)
2019
The characterization of materials used in the archaeological field needs an experimental approach in order to avoid the destruction or perturbation of artworks. In order to afford this purpose, a multi-analytical spectroscopic approach is regularly used. We combined non-invasive analysis by using handheld spectroscopic instrumentations (mainly XRF and Raman spectrometers) in order to characterize the wall painting preserved in the church of S. Maria delle Palate at Halaesa Arconidea archeological site (Tusa, Messina, Italy). The aim of the work is the characterization of the nature of pigments used for the realization of the wall painting. The wall painting, probably representing St. Franci…
Mediterranean Great Conversation
2015
The exit from the Mediterranean emergency requires rethinking its identity in a new perspective. This means recognizing its legitimate role as a “Great Sea in Between”, as a cultural interface able to connect all the citizens that address to it, in everyday life and as individuals, involving them in a real “great conversation” based on the design disciplines. Design, Brand, Visual Identity, Packaging, Social Media, Fashion, Food, Architecture, Music may be powerful antidotes to the immobility of those who mourn a lost Mediterranean harmony and also a viable alternative to the ethnic closure led by the proponents of the Clash of Civilizations.
From Historical Silk Fabrics to Their Interactive Virtual Representation and 3D Printing
2020
The documentation, dissemination, and enhancement of Cultural Heritage is of great relevance. To that end, technological tools and interactive solutions (e.g., 3D models) have become increasingly popular. Historical silk fabrics are nearly flat objects, very fragile and with complex internal geometries, related to different weaving techniques and types of yarns. These characteristics make it difficult to properly document them, at the yarn level, with current technologies. In this paper, we bring a new methodology to virtually represent such heritage and produce 3D printouts, also making it highly interactive through the tool Virtual Loom. Our work involves sustainability from different per…
The virtual reconstruction of the minaret of Mansourah mosque (Algeria)
2015
This contribution synthetically addresses some of the photogrammetric solutions available today in the field of architectural-archaeological survey and the related applications outcome, evaluated during both the acquisition phase of metric data than in those of effective yield of refunds infographics. Therefore, we have focused on the virtual reconstruction of one of the most emblematic and symbolic building of the Algerian culture, the mosque of Mansourah, returning the minaret as it appeared before its partial collapse, namely correspondent in geometry, textures, and colours. The work is part of a larger research project to promote knowledge and dissemination of Algeria cultural heritage,…
Diagnostics for the knowledge: the case of the tower of Palazzo Termine Pietragliata in Palermo (Italy)
2015
[EN] Developing a methodological approach is crucial to assess the state of conservation of a monument, starting from the overall analysis, progressively moving from small to medium scale and reaching the grand scale at the end. Considering the territory, causes are investigated in order to understand the propensities, as well as considering a single monument, evidences are carefully read to assess the overall conditions, that will be lately detailed by the analysis on materials and their degradation. The object of this study is the tower of the Palazzo Pietragliata in Palermo, one of the most important examples of the late Gothic civil architecture in Sicily. The Palace, built in 1473 by P…
Methods to Evaluate Lighting Quality in Educational Environments
2015
Abstract The current standard for lighting of indoor work places (EN 12464-1) essentially prescribes values of photometric quantities (illuminance, Unified Glare Index, etc.); therefore it does not allow a comprehensive analysis of the luminous environment. In Italy, educational buildings do not always comply with the standard requirements for lighting. Therefore an analysis of their current state is needed and this paper illustrates two methods, developed by the authors, to carry out this investigation: the former is based on the analysis of luminance maps obtained through the HDR imaging technique whereas the latter focuses on the evaluation of non-visual effects of light.
Visually low-impacting methods for the measurement of parameters related to IAQ risk indicators in exhibition halls
2021
Microclimate for cultural heritage plays a fundamental role in the degradation process of artefacts exhibited in museums. Generally, the Indoor Air Quality (IAQ) monitoring inside museums is based on conventional measurements of thermo-hygrometry parameters and longtime averaged measurements of atmospheric pollutants’ concentration. Unfortunately, all these approaches require electric supply and are usually characterized by a noticeable visual impact on the exhibition space, which clearly negatively affects the visitors’ experience. This paper intends to revisit and discuss a methodology (and its test application on field, to estimate the risk of damage of three artefacts displayed in an ol…
The Museum of Engines and Mechanisms. More Than a Century of History of Technology
2015
The Museum of Engines and Mechanisms of the University of Palermo has preserved more than 300 pieces, which collectively narrate the evolution of science and technology in the field of fluid machines and their components and testify to the development in scientific disciplines, technologies and industrial applications over the course of more than a century. A rigorous chronological path through the various typological groups allows for a historical walk through the last 150 years, in the area of automotive, airplanes and marine engines; hydraulic machines and stationary engines; mechanical measurements and laboratory devices for scientific and educational purposes. The collection is availab…
