Tree species influences diversity of ground-dwelling insects in afforested fields
2015
Abstract Impaired natural ecosystems, such as agricultural lands, are restored toward original or other target stage. Because the long agricultural history has changed the physical, chemical and biological features of the soil, afforested fields can harbor novel species assemblages and interactions. Our overall aim was to quantify the diversity of ground beetles and ants in early successional afforested fields. In a large scale field experiment, we compared plots that had been afforested 25 years ago by planting monocultures of birch, pine or spruce trees. A total of 4080 carabid individuals representing 41 species, and 131,933 ant individuals representing 15 species were recorded. Both the…
Per la conservazione partecipata, consapevole e diffusa dell'architettura storica e religiosa
2016
Il saggio Per la conservazione partecipata, consapevole e diffusa dell’architettura storica e religiosa è un contributo per meglio conoscere e dunque conservare, facendo fruire, il patrimonio delle preesistenze architettoniche con destinazione religiosa, partendo dal caso delle chiese di Bagheria, ma proponendo un apporto generale sia per la stessa conservazione, ma anche per il dovuto adeguamento liturgico. Infatti, non solamente s‘impone la conservazione del patrimonio storico e religioso, ma unitamente l’adeguamento liturgico secondo il concilio Vaticano II e dei successivi apporti pastorali offerti dalla Conferenza Episcopale Italiana. Nel saggio si sottolinea che qualsiasi nuova aggiun…
Restoration of a XVII Century’s predella reliquary: From Physico-Chemical Characterization to the Conservation Process
2021
We report on the restoration of a XVII century’s predella reliquary, which is a part of a larger setup that includes a wall reliquary and a wooden crucified Christ, both belonging to the church of “Madre Maria SS. Assunta”, in Polizzi Generosa, Sicily, Italy. The historical/artistic and paleographic research was flanked successfully by the scientific objective characterization of the materials. The scientific approach was relevant in the definition of the steps for the restoration of the artefact. The optical microscopy was used for the identification of the wood species. Electron microscopy and elemental mapping by energy-dispersive X-ray (EDX) was successful in the identification of the l…
Antifouling Mortars for Underwater Restoration
2022
This research has focused on the assessment of the compositional features and mechanical and antifouling performances of two different mortars formulated for an underwater setting, and which contain Mg(OH)2 as an antifouling agent. Regarding the mechanical characterization, the uniaxial compressive strength and flexural strength were measured. The composition of the materials was explored by differential thermal/thermogravimetric analysis (DTA-TG), X-ray diffraction analysis (XRPD), and scanning electronic microscopy (SEM) coupled with EDS microanalysis. The assessment of the biological colonization was evaluated with colorimetric analysis and image analysis. The results suggest that both m…
La Reggia di Venaria Reale in Italy and Palacio Real de Aranjuez in Spain: history, restoration and significance, comparative study between Two Royal…
2017
La investigación relaciona dos sitios reales, La Reggia di Venaria Reale en Italia y el Palacio Real de Aranjuez en España, confrontando su desarrollo histórico y arquitectónico, las obras de restauración llevadas a cabo, los criterios para su inclusión en la Lista de Patrimonio Mundial y su uso hoy en día como museos. El estudio comparativo muestra cómo ambos palacios se usaban inicialmente como residencias de caza en lugares con abundancia de agua y pesca. Además, los dos están ubicados cerca de las capitales políticas de su tiempo; esto es, Turín y Madrid. El hecho que el mismo arquitecto – Filippo Juvarra estuviera presente en ambas residencias reales contribuye a las similitudes, y en …
Everyday aesthetics on staycation as a pathway to restoration
2017
This multidisciplinary study enforces a suggested link between everyday aesthetic experiences and restoration. The studied phenomenon is staycation, a short-term holiday spent at home or at one’s home region, to identify how people use a (culturally) familiar environment for everyday aesthetic enjoyment and how that influences restoration. This focus minimises the potential effect of long-distance travel, novelty and escapism to restoration. Staycation has not been studied before from the perspective of everyday aesthetics and restoration. I explore staycation through a lens of qualitative media analysis; history and empirical research of holiday-making; and theories in everyday aesthetics.…
THE MOSAIC OF THE FRIGIDARIUM OF “VILLA BONANNO” IN PALERMO: MINERALOGICAL AND PETROGRAPHIC ANALYSES FOR IN SITU CONSERVATION AND RESTORATION INTERVE…
2018
The topic of this study was the mineralogical and petrographic characterization of bedding mortars (made of different layers) and tesserae of Roman age (3rd century A.D.), taken from the mosaic of the Frigidarium of “Villa Bonanno”, brought to light by archaeological excavations conducted in the historical centre of Palermo. The collected samples have been analysed by thin-section optical microscopy (PLM), and scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS). The study was aimed to define the “recipe” (composition of aggregate and binder, aggregate size distribution, aggregate/binder ratio), in order to assess the provenance of raw m…
Ammonium phosphate method in preservation of marble artifact
2022
In questo lavoro si studiano gli effetti dell'uso del fosfato di ammonio come consolidante nell'ambito del restauro e del consolidamento di una colonna binata nel lato est del chiostro di Santa Maria La Nova a Monreale, Palermo, Italia This paper studies the effects of using ammonium phosphate as a consolidating agent in the restoration and consolidation of a binata column in the east side of the cloister of Santa Maria La Nova in Monreale, Palermo, Italy
Rapid change in forms of inorganic nitrogen in soil and moderate weed invasion following translocation of wet meadows to reclaimed post‐industrial la…
2019
Anthropogenic expansion and loss of natural environments calls for the more sustainable use of resources, including land. To combine the conservation of highly valuable meadow habitat with reclamation of post‐industrial land, 1.3 ha of turf were translocated from an urban area to basins constructed near an abandoned quarry. In contrast to the usual method of choosing similar habitats as salvage sites, the selected quarry possessed different environmental properties to the meadows, challenging their acclimatisation. To evaluate the project, we monitored three meadows (Molinion caeruleae alliance) for three seasons: immediately before the transfer and for 2 years afterwards. We recorded veget…
