Authors: Lo Monaco, Angela; Picchio, Rodolfo; Sciascia, Nunziatina Abstract: The ancient trees in parks, gardens and avenues are the historical evidences of an aesthetic choice of the trends and inspirations of the designers. They also represent a valuable source of information on events that occurred during their existence. Xylological analysis conducted on the trunk sections make it possible to determine the age of the trees, thereby estimation of the plantation period was possible with a sharp precision as well as to identify growth anomalies which could mark specific events, such as climatic, biological or antropic incidents, occurred over time. Even though, the trees could be dead, their stump could be found which is a valuable research tool despite the absence of written records. The aim of this study is to determine the age and origin of the Quercus ilex L. trees by analysing the annual rings identified on the sectioned disks. Four stumps of Quercus ilex L. were obtained from the “Gallerie” (avenues) leading to the Pope’s historical residence at Castel Gandolfo and were sectioned from the basal region. The annual rings from the sections reveal that all the trees are the same age and are placing their first years of life in the mid-nineteenth century. The characteristic features of the annual rings also reveal that the trees are of asexual origin. In conclusion, this study proves that xylological analysis is an interesting approach for accurate understanding of historical events in the urban systems and for reading evolutionary processes of the green component which undoubtedly have an "environmental" value as well as decorative, historical and artistic ones. 2009-12-31T23:00:00Z http://hdl.handle.net/2067/2007 Title: Caratteristiche tecnologiche del legno proveniente da una fustaia di pino e da un ceduo di roverella percorsi da incendio rispettivamente in località Calambrone (PI) e Umbertide (PG) Authors: Lo Monaco, Angela; Moretti, Nicola; Picchio, Rodolfo; Todaro, Luigi; Quartulli, Stefano Abstract: Obiettivo generale del presente programma di ricerca, svolto in stretta integrazione fra le unità coinvolte, è quello di indagare sulla qualità del legname proveniente da due boschi di pino marittimo e di roverella percorsi da incendio. Per le fustaie di pino marittimo l’indagine è stata rivolta principalmente alle caratteristiche del legno ritraibili dal popolamento dopo uno e due anni successivi al passaggio del fuoco. Per il ceduo di roverella è stata condotta un’indagine sulla caratterizzazione tecnologica del legname ritraibile dalle matricine e dai polloni nonché sulle diverse destinazioni d’uso ed idoneità dei materiali. 2007-12-31T23:00:00Z http://hdl.handle.net/2067/1751 Title: Preservation and usage: the Altar Machine in the Church Mother of Gangi (Palermo, Italy) and its microclimate. Authors: Lo Monaco, Angela; Marabelli, Maurizio; Pelosi, Claudia; Salvo, Michele Abstract: The aim of this work has been to study the correlation between delicate poli material artefacts, like painted wooden sculptures, and their microclimate. In particular the Altar Machine in the Church Mother of Gangi, a little town near Palermo (Italy), has been investigated. The Machine is constituted by carved and painted wood and a complex system of winch and pulleys allows to move various statues and parts of the Machine in accordance with the baroque scenographic machineries. The microclimate of the Machine has been investigated in order to verify if the thermoigrometric values fall within the tolerance intervals that, for wood and painted wooden sculptures, has been set between 19 and 24 °C (temperature) and between 45 and 60 % (relative humidity, RH%)[1]. Analyses for the identification of wood species and for the study of the painting materials have been also carried out.

Meno consueto è riscontrare il legno di questa specie in manufatti artistici. Nel presente lavoro vengono presi in esame alcuni manufatti che per tipologia si possono considerare, oltre che di interesse storico-artistico, anche devozionale. I problemi conservativi che emergono dall’esame di queste opere vengono affrontati con esempi significativi, anche in relazione a moderni metodi di intervento. Description: Il Convegno si è svolto in concomitanza con il 1st European Congress on Chestnut e l'evento, nel suo complesso, è stato denominato Castanea 2009. Gli atti del 1st European Congress on Chestnut sono pubblicati su Acta Horticulturae dall'International Society for Horticultural Science (ISHS). 2008-12-31T23:00:00Z
