Anamnesi di un’architettura del Novecento, manifestazioni patologiche e tecniche per il risanamento: il caso dello Stand Florio a Palermo
2010
Il poster mostra l'anamnesi di un architettura del XX secolo, ed evidenzia le manifestazioni patologiche e le tecniche per il suo restauro conservativo. The poster shows the case history of a twentieth century architecture, and underlines the pathological manifestations and techniques for its restoration.
Il tema delle absidi nelle Cattedrali normanne di Palermo e Cefalù tra storia, storiografia e restauri
2021
The essay illustrates the main characteristics of the Norman apses of the Cathedrals of Palermo and Cefalù, with specific reference to the themes of the cleristory (or internal gallery or ambulatory) and the relative connections at height . These areas, in Sicilian architecture in which Arab, Byzantine and Norman characters are hybridized in a splendid mix, have been the subject of a rich Sicilian historiographical production, which is accounted for. The interpretation of history and of the transformations that have affected complexes of such high value, experienced through documents and critical reasoning on the reliefs with the hypothesis of restitution, allows us to make a contribution t…
Condition and Role of the Norman Cathedrals in the Fourteenth Century: Maintenance, Restoration and Renovation
2022
After conquering Sicily between 1061 and 1091, the Normans built new cathedrals that modified not only religious life, but also architecture and urban layout. Dramatic events, like wars, earthquakes, and fires, clumsy restorations and culpable inaccuracy have profoundly altered the appearance of Norman cathedrals. The aim of this paper is to analyse the state of conservation of the Cathedrals of Palermo, Monreale, Messina and Agrigento in the fourteenth century, when Sicily was profoundly affected by the war between the Angevins and the Aragonese that lasted ninety years and impoverished the island. The analysis of four case studies from the past will allow us to outline new perspectives fo…
Piano col colore! Mezzo secolo di contraffazioni nei centri storici
2010
The transformation dynamics of the ancient towns are completely changing the urban landscape of the historical countries in Italy in the last fifty years. The most superficial part of material constitutes the image of the architectures and plays a meaningful role in the perception of the historical districts that still characterize the contemporary city, but the aptitude for destroying architectural finishes and deleting superficial patina involves therefore to alter the character of the old towns irreversibly. It had to be obvious it would have been essential to conserve the authentic materials and signs of time that denote the historical authenticity of monuments, but new surfaces of plas…
A prospective, multi-center, practice-based cohort study on all-ceramic crowns
2021
The aim of this prospective, multi-center, practice-based cohort study was to analyze factors associated with the success of all-ceramic crowns.All-ceramic crowns placed in a practice-based research network ([Ceramic Success Analysis, AG Keramik) were analyzed. Data from 1254 patients with (mostly in-office CAD/CAM) all-ceramic crowns placed by 101 dentists being followed up for more than 5 years were evaluated. At the last follow-up visit crowns were considered as successful (not failed) if they were sufficient, whereas crowns were considered as survived (not lost) if they were still in function. Multi-level Cox proportional hazards models were used to evaluate the association between a ra…
Fracture resistance and the mode of failure produced in metal-free crowns cemented onto zirconia abutments in dental implants.
2019
The purpose of the investigation was to analyze fracture resistance and mode of failure of zirconium oxide (zirconia) abutments placed on dental implants bearing crowns of different esthetic materials: zirconia, lithium disilicate (LDS), and nano-ceramic resin, for replacing single teeth in the anterior sector. Eighty implant-abutment-crown units were divided into four groups: Group T-MC (control): 20 metal-ceramic crowns cemented onto titanium abutments; Group Z-Z: 20 zirconia crowns on zirconia abutments; Group Z-LD: 20 lithium disilicate crowns on zirconia abutments; and Group Z-NCR: 20 nano-ceramic resin crowns on zirconia abutments. Specimens underwent a fatiguing process (dynamic load…
Implant-supported metal-ceramic and resin-modified ceramic crowns: A 5-year prospective clinical study.
2018
Abstract Statement of problem Because of market demand for innovation, new restoration materials have been introduced without adequate testing; clinical failure may be the consequence, and clinical studies are needed. Purpose The purpose of this clinical study was to evaluate the biological and mechanical clinical behavior of implant-supported resin-modified ceramic crowns compared with that of metal-ceramic crowns. Material and methods Forty-two participants aged between 35 and 65 years received single implants in posterior edentulous sites. After the osseointegration period, half of the implants (selected randomly) (n=25) were restored with metal-ceramic crowns (MC group) and the other ha…
Combining land preparation and vegetation restoration for optimal soil eco-hydrological services in the Loess Plateau, China
2019
Abstract In semiarid terrestrial ecosystems, optimized eco-rehabilitation strategies, such as land preparations and planting vegetation, are keys to achieve a successful ecological restoration. Land preparations and vegetation are supposed to have the coupled and respective impacts on soil ecosystem services, which are still unclear now. In this study, eighteen experimental plots with six different combinations and repetitions of land preparations and vegetation were built in the Chinese Loess Plateau in 2014 and soil moisture storages (SMS), soil carbon stocks (SCS) and other soil nutrient stocks were calculated at 0–100 cm, also the effects of land preparations and planting vegetation on …
“Restorative Justice”, víctima y mediación. Tres conceptos en el nuevo paradigma de la entrópica Justicia penal” (‘Restorative Justice’, Victim and M…
2018
Spanish Abstract: La sociedad actual encuentra en los momentos en que vivimos un complejo, inquietante y paradojicamente contradictorio paisaje penal, en el que una imparable y abracadabrante produccion legislativa nos invade, en el que la esquizofrenia entre la proclamada ultima ratio del Derecho Penal y la expansion masiva del mismo se hace presente como eje central de las reformas legales, y en el que la tension entre la tutela y proteccion del ciudadano y una sobredimensionada busqueda de la “seguridad” –para la sociedad- encuentra su acomodo perfecto en sede penal. Los cambios, los bienes juridicos protegidos, el imparable aumento en calidad y cantidad de la criminalidad y la regresion…
Stakeholders’ Attitudes about the Transplantations of the Mediterranean Seagrass Posidonia oceanica as a Habitat Restoration Measure after Anthropoge…
2021
Anthropogenic impacts on Posidonia oceanica meadows have led to a decline of this ecosystem throughout the Mediterranean. Transplantations have often been prescribed as a compensation measure to mitigate the impacts caused by coastal maritime works. Here a Q methodology approach was used to investigate the stakeholders’ attitudes in four case studies of P. oceanica transplants realized in Italian waters. Twenty-two respondents were asked to score 37 statements, and the resultant Q-sorting was analyzed via an inverse PCA using the KADE software. Four discourses, corresponding to the significant axes in the factorial analysis were identified: science and conservation (F1), oriented at a rigor…
