Waterlogged archaeological wood: evaluation of consolidation treatments by calorimetry

2013

Upside-down ship’s kel-shaped vaults as a contemporary design criteria. The case of the Palace of the Dukes of Braganza in Guimarães (Portugal)

2015

A contemporary worldwide trend is exposing the structural elements of a building to create an articulate and complex architecture whose lines of force give robustness, stability and, at the same time, a sort of lightness and frivolity to the entire construction. However, the combination between the visual conception of architecture and the principles of statics is not new to the world of construction. Exposed structure as a design approach may be observed in many historical buildings, either public, religious or private, and in several cultural and geographical areas where exposed structures communicate power, solidity, and rigour along with an instance of economy and lightness. In this wor…

Sustainable Supercapacitors Based on Polypyrrole-Doped Activated Biochar from Wood Waste Electrodes

2023

The synthesis of high-performance carbon-based materials from biomass residues for electrodes has been considered a challenge to achieve in supercapacitor-based production. In this work, activated biochar has been prepared as the active electrode material for supercapacitors (SCs), and an effective method has been explored to boost its capacitive performance by employing polypyrrole (PPy) as a biochar dopant. The results for physicochemical characterization data have demonstrated that PPy doping affects the biochar morphology, specific surface area, pore structure, and incorporation of surface functionalities on modified biochar. Biochar-PPy exhibited a surface area of 87 m2 g−1, while pris…

Importance of millipedes (Diplopoda) in the autumn-winter diet of Scolopax rusticola

2019

Authors examined the autumn-winter diet of the woodcock Scolopax rusticola from 407 gizzard samples originating from Crimea and Italy, resulting in a high number of millipedes (Diplopoda) in all the samples; this prey item was particularly important in terms of weight percentage. The authors consider that calcium, highly present in millipedes, should be an important source for the woodcocks’ metabolism during the autumn-winter seasons.

Representations of the Life-giving Spring feast in Romanian iconography

2021

This article explores the development of the theme of the Life-giving Spring in Byzantine iconography. The path towards its establishment was initiated at the moment when a representation rule, an original convention was set. Thereafter, because of its diffusion in time and space, the theme became enriched by particular mentalities and sensibilities of the epochs and the communities that adopted it as a form of devotion for the Virgin Theotokos. As a result, the representations we have known so far are extremely varied. Contribution: The final purpose of this approach, as well as its contribution, is to highlight the diverse unity of the iconographic tradition and illustrate both the evolut…

Scientific studies for the restauration of two wooden arm reliquaries from the Cathedral of Palermo

2017

Dedicated to Saint Generosi and Saint Rosana, the reliquary arms, recalling the shape of a body part, are today located in the Relics Chapel in Palermo Cathedral. They are probably dated to the second half of the 18th century and are attributed to an unknown artist. The aims of this study were to investigate the decorative techniques, verify the state of conservation of the constitutive materials, measure the microclimate condition in the Relics Chapel, in order to set up a correct preventive conservation strategy. In this regard, an integrated scientific investigation was performed focusing on environmental monitoring (thermo-hygrometric parameters) by HOBO system, characterization of mate…

Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…

2014

The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…

Scientific restoration and historical-artistic research of the Saint Giovanni Battista wooden polychrome gilded high-relief from Saint Barbara church…

2022

Lo scopo della presente ricerca è quello di descrivere i risultati del restauro scientifico supportato dalla ricerca archivistica e dall'analisi storico-artistica, dell'altorilievo ligneo policromo raffigurante San Giovanni Battista della chiesa di Santa Barbara a Naro, Agrigento, Italia, parte di un alterpiece di fine XV - inizi XVI secolo The purpose of the present research is to describe the results of the scientific restoration, supported by archival research and art-historical analysis, of the polychrome wooden high-relief representing St. John the Baptist from the church of Santa Barbara in Naro, Agrigento, Italy, part of a late 15th- to early 16th-century alterpiece

Modelli lignei e architettura in Sicilia tra XV e XVI secolo

2020

La realizzazione di modelli lignei nel processo di creazione di opere architettoniche in Sicilia è documentata a partire dalla fine del XV secolo. Oltre ad alcune testimonianze nel campo dell’architettura militare, si tratta principalmente di edifici chiesastici, nei quali una articolata committenza svolge un ruolo propositivo. Nell’ambito delle comunità benedettine, in particolare, trova riscontro l’esistenza di un modus operandi che include la realizzazione di modelli lignei. Da tale modalità operativa, tuttavia, non rimane esclusa l’architettura civile. Questo contributo analizza le testimonianze relative a tale casistica, valutando l’attendibilità per il contesto in esame dei parametri …

Proceeding Book of 12th European Symposium on Religious art, Restoration & Conservation

2022

Fundamental contribution to filling out the condition reports of the work of arts involved in temporary exhibitions is provided by non-invasive investigation techniques. Investigation, carried out before and after the movement, allow to collect objective data to monitoring the surface or structural alterations and defining the state of conservation, representing an important moment of deepening of knowledge. Generally, these aspects often are left to photographic documentation and observations by conservators and curators. An example of good practice is represented by the case of the Saint Gregory Polyptych (Antonello da Messina, 1473) belonging to the Regional Museum of Messina (Italy). Th…
