LA MICROSCOPIA ELETTRONICA (SEM, CLSM) PER L’ANALISI DI MICROSISTEMI BIOLOGICI CHE COLONIZZANO I BENI CULTURALI
2012
RIASSUNTO - Il degrado dei materiali con cui sono realizzate le opere d’arte, è spesso causato dall’attività di macro e micro organismi (piante, insetti, licheni, alghe, batteri, attinomiceti etc.), denominati biodeteriogeni. Presenti in tutti gli habitat terrestri, costituiscono un serio problema per la conservazione sia in siti outdoor sia confinati, come biblioteche, archivi, istituti mussali, depositi e, comunque, in tutti quei luoghi dove si attua la conservazione/fruizione dei manufatti. In genere, non vi è luogo di conservazione che non mostri tracce di parziali o estese infestazioni/colonizzazioni che comportano alterazioni più o meno consistenti dei manufatti presenti. Le alterazio…

Querelle épigraphique entre deux savants : l’exemple de la correspondance, publiée dans la Revue archéologique de 1847, entre Antoine-Jean Letronne e…

Although Roman inscriptions have attracted interest since the Renaissance, epigraphy was not acknowledged as a science in its own right, with its own ruleset and methods, until the mid-19th century. Henceforth every newly discovered inscription was duly documented and distributed across an ever-growing and influential network of European scholars, giving birth to an extensive system of scholarly correspondence connecting every individual researcher with the community, from the provincial antiquarian who, as a precursor to « field archaeology », would discover the inscriptions, to the Parisian scholar who would gather and examine every inscription sent his way. One such epistolary intercours…
Degradation of stone materials in the archaeological context of the Greek-Roman Theatre in Taormina (Sicily, Italy)
2010
In the present work results on the degradation phenomena of stone materials in the Ancient Theatre of Taormina, one of the most important Greek–Roman monuments of Sicily, are reported. Artificial stone materials in different conservation conditions were investigated. Samples of salt efflorescences from brick walls and degraded setting mortars were taken from the open gallery in “summa cavea”. The chemical, physical and structural characterization was performed by means of X-Ray Photoelectron Spectroscopy (XPS), X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF), both in situ and ex situ. Results showed that the deterioration of stone materials is due to the aggressive action of the enviro…
Les collections protohistoriques au musée de Lons-le-Saunier, Centre de Conservation et d’étude René Rémond
2020
Since its creation in 1817, the Lons-le-Saunier museum has been intended to house all the archaeological objects unearthed in the Jura department. Even if some collections are not included, the reserves contain most of the finds from the Jura. Protohistory plays an important role, with emblematic sites such as the Planches cave or the Chavéria necropolis. However, these collections have different legal statuses: collections listed in the museum's inventory (old collections and recent acquisitions) and collections kept in the museum but whose entry has not been regularised. With the aim of building a new museum, a vast project must be carried out in order to make the necessary acquisitions a…
On site consolidation of burnt and partially charred wood in dry conditions
2011
Abstract Forty years ago in a xx th-century church in Torino, a small fire partially burned some of the decorative external boards of the sound-box of the organ. The focus of this present work was to find a treatment able to consolidate partially burnt wood in dry conditions, in which the external charred layer would be lost if not well preserved because of its incoherence. The product had to be applied onsite on an architectural structure intended to be reused again (and not simply exhibited). This circumstance is rarely encountered in the conservation of wooden Cultural Heritage. The efficacy of treatments was evaluated on the basis of a suitable and original experimental methodology, whi…
Scientific communication in museums through presential mediation : Case study le Pavillon des Sciences
2014
In science museums and science centers, "presential" mediation positioning a mediator and the public in the co-presence of objects within a dedicated environment, remains relatively unknown. From a Communication Science perspective, analyzing actual situations transcends the simple provision of information, and focuses on the significance of third party forms within the construction of meaning. Presential communication is transient and centered on the words and gestures of an embodied third party. It provides a greater potential for interactions around practical situations, unlike other media (i.e. an exhibition). The purpose of this research is to question the rightful place of these speci…
