YOCOCU-2010

YOCOCU-2010 (40)

YOCOCU was born in 2008 from an idea by Andrea Macchia, Luigi Campanella and Ernesto Borrelli with the aim to realize a network among young professionals and researcher working in the field of Cultural Heritage.

YOCOCU nasce nel 2008 da un’idea di Andrea Macchia, Luigi Campanella ed Ernesto Borrelli con lo scopo di creare un punto di incontro tra i giovani professionisti e ricercatori che lavorano nei diversi settori della conservazione dei beni culturali.

A due anni dalla sua nascita YOCOCU si è evoluto, divenendo un simbolo, un luogo virtuale dove la comunità di giovani riunita da scopi comuni ha potuto esprimere le proprie storie, i loro contributi alla ricerca e alla crescita culturale nei diversi campi che compongono il settore dei beni culturali: chimica, fisica, biologia, restauro, archeologia , architettura. Giovani professionisti e ricercatori sono chiamati con questo evento ad accrescere e rafforzare la consapevolezza di essere gli attori della società presente e futura e a costruire la loro identità come motori dello sviluppo di nuove conoscenze nel campo.

I professionisti più esperti sono invitati a raccontare la loro esperienza e a fornire le chiavi di lettura dell’attuale conservazione per definire insieme il futuro della conservazione

Una sfida intrapresa in un mondo in continua e veloce trasformazione che va affrontata tra competenza e creatività che interessa materiali, metodi e tecniche, resa unica dal contributo di tutti sia giovani che esperti.

YOCOCU è così un network che costituisce un punto di incontro per collaborazioni trasversali, interdisciplinari ed internazionali, ma soprattutto è una bella storia composta da vari capitoli, scritti da ogni partecipante. Tante storie vicine e lontane nell’argomento, nella tecnica, nella tipologia di intervento, tutte ovviamente interessanti.

Abstract
El-Mansoura city is one of the Egyptian intermediate cities in the Nile delta, The city center heritage mostly are in the European Mediterranean style because of the presence of the foreigner comunities in the city during the nineteenth and twentieth centuries. As many other Egyptian intermediate cities, the city heritage suffers from lack of maintenance and absence of organized conservation programs. El-Mansoura architectural heritage are divided into main five zones around the city center, The “private palaces and villas zone” it was the residence of the aristocratic Egyptians, The “Northern city center” it was the administration zone near the port, The “Commercial center” with high concentration of commercial activities, “El-Mokhtalat neighborhood” it was the residence of the foreigners and elite Egyptians, “Torel neighborhood” it was a combination of private villas. Their are some trials to preserve and restore the city heritage but normally they are individual trails, now there is some projects to make urban development of the valuable zones and that will lead to effective conservation projects in the future.

Abstract
In the last years researchers are devoted with an increasing interest to the safeguard of the monumental and architectural heritage. A remarkable scientific production has been published and, contemporarily, economic investments have been allocated in that field. Despite that, professionals of the enterprises, essentially having the technical surveyor high school qualification, are still unaware of the techniques and know ledges in the field of Cultural Heritage and, in some cases, they persevere to apply techniques and materials advised for modern home building to the monumental and architectural heritage. With the purpose to overcome these gaps and to train the future surveyor professionals, the project called “Laboratorio dei Beni Culturali” (financed by the Ministero dell’Istruzione, dell’Università e della Ricerca -MIUR), was promoted and designed for the first time for the students of a technical high school. The goal of the project was to contribute to the formation in the field of the Cultural Heritage, by adding to the specific high school training course a new laboratory unit in order to improve the competencies in the field of the diagnostics of the cultural heritage. During the project, different laboratory experiences were accomplished on three types of stones and on some samples of plasters coming from historical buildings of Ortigia (Syracuse) in order to characterize and analyse them. Other measurements were addressed to the determination of environmental parameters, such as, for example, relative humidity and temperature. All the results obtained agree with the data reported in literature. All the experiences, mainly having educational character, were accomplished in the chemistry and materials laboratories of the Istituto Statale Istruzione Secondaria for surveyor “Filippo Juvara” of Syracuse by using the instrumentation there present.

Abstract

In the last decade, the use of 3D reconstructions of antiquities has become a well established trend that is now widely applied to increase the value of cultural heritage. Only recently 3D computer graphics have been interpreted also as a cognitive tool for the archaeological research, especially with regards to the great monuments of classical civilization. The decision to produce virtual models of pre-protohistoric monuments, often characterized by bad preservation of the remains and lack of other classes of documentary sources, can be considered as a real challenge for archaeologists and experts. This work, fitting the interests of Catania University’s Archeomatica Project (www.archeomatica. unict.it), aims to create a multi-phase virtual model, integrating the natural landscape and human constructions, of the Polizzello Mountain site (Mussomeli, CL), that flourished between the 10th and the 4th century BC. In particular, in this paper, the 3D models of two large holy enclosures are presented. They were interpreted as the focus of the activities of the acropolis of the site between the 8th and the 6th century BC. The elaboration has taken into account all the classes of data collected during the excavations, which have been recently completed, in order to give the philologically correct replica of what the buildings were at the time of their use. The work tool chosen is Blender, an open source, multiplatform software that is extremely powerful and versatile in 3D modelling, rendering and animation.

Abstract
Recently wide scale archaeological excavations held in Azerbaijan were discovered new archaeological monuments dating to different periods. Most of them were of scientific research character. In our co-authorship report we would like to bring to world’s scientific community notice excavation, conservation and utilization of three archaeological sites involved in Achaemenid and Antique periods. According to the only scientific aims preserving of this buildings were set aside mainly in Soviet periods. The archaeological remains, left to decay after excavations, show low resistance to the natural conditions, characterized by the frequent cycles of wetting and drying, thawing and freezing and wind erosion. Taking into consideration that in the construction of the building used mainly mud brick and lime stone, these monuments undergo of natural and anthropogenic danger. Conserving the monuments in a complex together with archaeological studying is the main responsibilities. The first samples of the utilization of archaeological sites are from urban archaeology when ruins of architectural constructions were unearthed and preserved in the formed city. Preserving these sites as a cultural heritage it is planned to include these areas in the tourist route together with other monuments in the region.

Abstract
The ruins of the medieval town of Shamkir are situated in the western region of Azerbaijan Republic, in the north-eastern part of the Lesser Caucasus, on the left coast of the Shamkirchay River, on the Silk way. One of the most important achievements of the archaeological excavations is the complete study of the citadel and partial study of the town tower. Fortification constructions evoke special interest in learning the military architecture of Azerbaijan. Taking that fact into consideration urgent actions of preserving are being implemented. First the danger of destruction of the central tower of the eastern wall of the citadel was avoided by its preservation. At the same time the dilapidated arches of the excavated arch spans of the construction site on the excavation
area No 5 were partially preserved and partially restored for the progeny. Only the construction materials gathered during the excavation and the strengthening solution corresponding to the one of the historical period in question were used during the preservation.

Abstract
The Ostia Marina project headed by prof. Massimiliano David and dr. Angelo Pellegrino started in 2007 thru an agreement, renewed in 2010, between the Soprintendenza Archeologica di Ostia Antica, now Soprintendenza Speciale per i Beni Archeologici di Roma, and the Department of Archaeology, University of Bologna, for the study of the area outside Porta Marina. The research has focused on the insula IX, regio IV, only marginally affected by the earthworks of the ‘40s. The preliminary surveys and the study of archive documents about the area outside Porta Marina were conducted in 2007. In 2008 the archaeological investigations was supported by two geophysical analysis to emphasize the potential of the site: the first, using the georadar,
by Dr. Carlo Rosa, (Lerici Foundation), while the second, geomagnetic, by Dr. Helmut Becker (Becker Archaeological Prospection of Beuerberg - Germany).
In 2009 was conducted the first campaign of excavations, under the direction of prof. Massimiliano David, prof. Dario Giorgetti for topographical aspects and Dr. Maria Luisa Stoppioni to catalog and study the artefacts.

Abstract
Dwellings are individual’s primary anchor in an environment and represent the vast range of inhabitation around the world. In World Heritage studies, the enlarging number of World Heritage Sites has included certain dwellings of diverse meaning. However, the subjectivity and characteristics of dwelling properties seem hidden, even neglected. Dwelling itself rarely plays the main role for inscription; in contrast, it often acts as adjunct submissive to other powerful hegemonies. The main aim in this paper is initially to formulate a framework of conceptual thinking on the significance of World Heritage dwellings. It is also necessary to explain the rationale behind the dwelling inscription, to classify and interpret diverse meaning and then to raise awareness how authentic the life is.

Abstract
Some studies about PVA based gels and their applications as cleaning tools for painted surfaces are presented. New formulations of this class of high viscosity polymeric dispersions have been used to remove oxidized varnishes coating “Santo Stefano” by Ludovico Cardi detto il Cigoli (a 17th century oil-on-wood panel) and to remove Paraloid B72 from wall paintings in SantaMaria della Scala, Siena. Rheological properties have been studied in order to investigate themechanical behaviour of hydrogels with particular attention to their easy removal simply by apeeling off from the surface.

PROBLEMS OF ILLUMINATION OF CULTURAL HERITAGE: THE CASE OF REALGAR

Andrea Macchia, Giorgia Roscioli, Enrico Greco, Luigi Campanella, Adriana Maras

Abstract
To plan an exhibition of cultural heritage in a museum it’s necessary to consider different aspects, firstly the safe conservation of the exposed objects, secondly the optimal vision offered to visitors for their satisfactions and enjoyment. With regard to conservation aspects it’s necessary to consider both the possible deterioration due to the radiation falling on the object and other aspects such as micro-climate conditions, frequency of visitors. Further important needs concern cheapness and low frequency of maintenance interventions by the curators. The study intends to examine existing light sources, in particular their lighting “quality” and to develop a new system, based on LED technology, able to combine visual valorization with protection of Cultural Heritage. In first phase the material to be investigated was realgar, a natural and artificial mineral, whose molecule consists of four covalent bonds As-S. In the presence of oxygen it undergoes a cyclic and autocatalytic photochemical transformation which causes an anisotropic volume increase of the crystalline unit cell and formation of AS4S4 in the form, known as pararealgar. Analytical measurements have confirmed this hypothesis and allowed the definition of the reaction kinetics. In these experiments a 100 watt halogen lamp was used. Currently, the study is in progress, in order to understand the behavior of the pigment in the binder, the damages suffered and the eventual positive action of the degraded compound against biodegradation.
