Opere d’arte francescane dall’alto Belice corleonese alla Valle del Sosio
2013
Si analizzano opere d’arte, anche inedite, legate alla committenza francescana dell’alto Belice corleonese e della Valle del Sosio pubblicando documenti emersi nel corso della ricerca We analyze works of art, also unpublished, related to the Franciscan patronage of the Upper Belice Corleonese and the Sosio Valley by publishing documents that emerged during the research.
Mostrare l’invisibile: il soffitto trecentesco nascosto del convento di Santa Caterina a Palermo
2022
Digital surveying and representation technologies have been widely used for the visualization of works of art and architecture that no longer exist or have been moved from their original location. These researches share a common feature, that can be resumed by the motto “Display the invisible”, already used in research experiences [Colosi et al. 2015; Gambin et al. 2021]. The purpose of this research is the visualization of a 14th century wooden ceiling, painted by anonymous artists, that covered the hall used for the assembly of the Chapter in the convent of Santa Caterina, at the heart of the historic center of Palermo. The hall was reshaped at the end of the 18th century to serve as a sa…
The influence of the wooden equipment employed for cheese manufacture on the characteristics of a traditional stretched cheese during ripening
2015
Abstract The influence of the wooden equipment used for the traditional cheese manufacturing from raw milk was evaluated on the variations of chemico-physical characteristics and microbial populations during the ripening of Caciocavallo Palermitano cheese. Milk from two farms (A, extensive; B, intensive) was processed in traditional and standard conditions. Chemical and physical traits of cheeses were affected by the farming system and the cheese making technology, and changed during ripening. Content in NaCl and N soluble was lower, and paste consistency higher in cheese from the extensive farm and traditional technology, whereas ripening increased the N soluble and the paste yellow and co…
The traditional sacral wooden construction in Lithuania. An illustrated catalogue of building techniques for the safeguard and recovery of cultural h…
2015
La Lituania attualmente può annoverare un patrimonio di circa 600 edifici sacri in legno ancora esistenti, sui quali, ad oggi, non sono stati condotti studi approfonditi in merito agli aspetti storico/architettonici e tecnico/costruttivi. Questa tipologia di edifici costituisce un patrimonio della cultura architettonica locale da esplorare e conoscere, per garantirne la corretta conservazione e valorizzazione. La maggior parte di questi edifici di culto in legno versa in condizione di degrado poiché le comunità non sempre possiedono la dovuta attenzione e le competenze tecniche capaci per salvaguardare tale patrimonio. Le cause più frequenti di danno derivano da una inadeguata manutenzione,…
MICROSCOPIC TECHNIQUES (SEM AND OM) AND ANALYTICAL APPROACH TO CHARACTERIZE CONSTITUTIVE MATERIALS AND TECHNIQUE OF THE WOODEN FRAMES IN SICILY
2015
Nowadays artworks traditionally included in the category of applied or decorative arts are considered at the same level of fine arts getting over the old definition of minor art. According to this consideration an increasing number of studies and paper deals with the decorative arts and the Observatory for Decorative Arts in Italy “Maria Accascina” (OADI) was settled within the University of Palermo in order to study them. Nevertheless most studies deal with artistic and historic issues of applied arts and just few concern with the technique used, at least in the southern part of Italy. This paper is a systematic research concerning the constitutive materials and the executive techniques of…
Evolution of the lactic acid bacterial biofilms on different wood typologies applied for the production of vats intended for cheese making
2017
The present work was carried out to evaluate the lactic acid bacterial biofilms formation on wooden vat produced with seven different woods, derived from trees species grown in Sicily. The biofilm formation on the wooden surfaces was performed as reported by Gaglio et al. Microbiological and scanning electron microscopy analyses did not show differences in terms of microbial levels and composition within the neoformed biofilms (Fig.1). The specific investigation of Salmonella spp., Listeria monocytogenes, Escherichia coli and positive-coagulase staphylococci did not generate any colony for all vats before and after microbial activation. Lactic acid bacteria (LAB) populations dominated the s…
Transfer, composition and technological characterization of the lactic acid bacterial populations of the wooden vats used to produce traditional stre…
2015
The biofilms of 12 wooden vats used for the production of the traditional stretched cheeses Caciocavallo Palermitano and PDO Vastedda della valle del Belìce were investigated. Salmonella spp. and Listeria monocytogenes were never detected. Total coliforms were at low numbers with Escherichia coli found only in three vats. Coagulase-positive staphylococci (CPS) were below the enumeration limit, whereas lactic acid bacteria (LAB) dominated the surfaces of all vats. In general, the dominance was showed by coccus LAB. Enterococci were estimated at high numbers, but usually between 1 and 2 Log cycles lower than other LAB. LAB populations were investigated at species and strain level and for thei…
Persistence of wild Streptococcus thermophilus strains on wooden vat and during the manufacture of a traditional Caciocavallo type cheese
2012
The present work was undertaken to evaluate the influence of the wooden dairy plant equipment on the microbiological characteristics of curd to be transformed into Caciocavallo Palermitano cheese. Traditional raw milk productions were performed concomitantly with standard cheese making trials carried out in stainless steel vat inoculated with a commercial starter. Milk from two different farms (A and B) was separately processed. The wooden vat was found to be a reservoir of lactic acid bacteria (LAB), while unwanted (spoilage and/or pathogenic) microorganisms were not hosted or were present at very low levels. All microbial groups were numerically different in bulk milks, showing higher lev…
Microscopic approach to investigate constitutive materials and technique of San Vito wooden pulpit of Museo Diocesano of Palermo
2015
The aim of this research was to assess the techniques used to create and decorate the wooden pulpit of San Vito and to verify the state of preservation of the finishing materials of the artwork.
La traduzione costruttiva lituana negli edifici di culto in legno tra i secc. XVIII e XIX
2014
Lithuania is situated in a highly forested Northeastern Europe area and has a variety of wooden buildings. Among the wooden structures we enumerate the religious buildings, churches and bell towers, rich of historic values, presenting different forms and sizes, a complex design and stratified construction phases. The present work aims to study this interesting topic and intends not only to analyze the architectural typology but even more the technological and structural aspects, that had suggested the most influences on building techniques during the centuries.
