Prime verifiche sull’uso dello scanning total station Trimble SX10 per il rilievo architettonico dei beni culturali
2018
Il lavoro presenta alcuni test di rilievo di beni culturali eseguiti con l'ausilio della stazione totale scanner Trimble SX10. Le acquisiziomi sono state confrontate con i dati ottenuti da un comune laser scanner terrestre Faro Focus 3D S120. Come caso studio per effettuare i confronti è stato scelto il portico principale del Duomo di Monreale. I risultati ottenuti hanno evidenziato una buona rispondenza geometrica dei differenti dataset, anche in corrispondenza di dettagli di piccole dimensioni. Inoltre, l’utilizzo del Trimble SX10 è risultato particolarmente semplice ed intuitivo. Unico limite, per rilievi particolarmente complessi di beni culturali, potrebbe essere la velocità di acquisi…
FROM SCAN-TO-BIM TO HERITAGE BUILDING INFORMATION MODELLING FOR AN ANCIENT ARAB-NORMAN CHURCH
2022
Abstract. One of the most significant issues in Cultural Heritage is the management of ancient buildings to monitor their state of conservation or to plan actions in their maintenance; this issue can be now approached thanks to the use of the Scan-to-BIM process. This method allows the creation of parametric models into a BIM environment, which are capable of enhancing the geometrical representation of building elements and integrating different types of data.This paper shows the results of the research activities carried out by the Department of Engineering at University of Palermo (Italy) on applying the Scan-to-BIM approach to the survey and the modelling of an ancient Arab-Norman church…

Integrated surveying techniques in cultural heritage documentation
2007
This paper is focused on integration between laser scanning data, CAD modelling and photogrammetric data collected during the survey of one façade of the monument called “Quattro Canti” in the historic centre of Palermo. The investigation has been directed to the production of a 3D photorealistic model of the monument. The “Quattro Canti” monument is formed by four cylindrical façades facing the square where the older streets of Palermo intersect; each façade has a symbolic reference to one of the seasons and is divided in four levels. The façade called “Canto dell’Autunno” has been surveyed both with laser scanning and with photogrammetric techniques. Laser scanning data have been collecte…
Rock decay phenomena and collapse processes in the “Latomiae del Paradiso” in Syracuse (Sicily)
2014
The Latomiae (origin: Greek latomia, from laas, las stone plus –tomia tomy ) del Paradiso in Syracuse are Magna Graecia rock quarries, located in the coastal areas of Southern Italy and internationally renowned for their impressive environment. The few historical technical records do not help clarify the events that led to their current configuration since a series of instability phenomena occurred due to decay processes over time. Through a geotechnical back-analysis, this work highlights the failure phenomena, which may have led to the current configuration of the easterly side of the Latomiae del Paradiso. The back-analysis process was carried out by means of numerical modelling, support…
Sacubitril/valsartan reduces indications for arrhythmic primary prevention in heart failure with reduced ejection fraction: insights from DISCOVER-AR…
2021
Abstract Aims This sub-study deriving from a multicentre Italian register [Deformation Imaging by Strain in Chronic Heart Failure Over Sacubitril-Valsartan: A Multicenter Echocardiographic Registry (DISCOVER)-ARNI] investigated whether sacubitril/valsartan in addition to optimal medical therapy (OMT) could reduce the rate of implantable cardioverter-defibrillator (ICD) indications for primary prevention in heart failure with reduced ejection fraction (HFrEF) according to European guidelines indications, and its potential predictors. Methods and results In this observational study, consecutive patients with HFrEF eligible for sacubitril/valsartan from 13 Italian centres were included. Lack o…
Riarticolare la giustizia. L'impegno semiotico del Giorno della civetta
2020
Lo studio usa strumenti della semiotica strutturale e interpretativa per proporre un close reading del Giorno della civetta. L’analisi così condotta mette in evidenza come il testo s’impegni a ristrutturare la competenza interpretativa del let-tore e, con essa, alcuni valori alla base della sua coscienza civile, con particolareriferimento alla verità e la giustizia. A partire dalla costruzione delle tensioni narrative intorno a questi due valori, si mette in evidenza lo slittamento semanticoche consente di leggere «il primo romanzo di mafia» come «il primo romanzosull’antimafia». The study uses tools of structural and interpretative semiotics to propose a close reading of the Day of the Owl…
Leptin and the OB-receptor as anti-obesity target: recent in silico advances in the comprehension of the protein-protein interaction and rational dru…
2014
The OB-receptor or leptin receptor (LR) is crucial for energy homeostasis and regulation of food uptake. Leptin is a 16 kDa hormone that is mainly secreted by fat cells into the bloodstream. Under normal circumstances, circulating leptin levels are proportionate to the fat body mass. Sensing of elevated leptin levels by the hypothalamic neuro-circuitry activates a negative feedback loop resulting in reduced food intake and increased energy expenditure. Decreased leptin concentrations lead to opposite effects. Therefore, rational design of leptin agonists/antagonists could be an appealing challenge in the battle against obesity. The Leptin/LR interactions have been studied in several works b…
Obésité et grossesse : étude de l'influence d'un marqueur de l'obésité sur les mécanismes cellulaires et tissulaires de l'accouchement dans un modèle…
2012
Maternal obesity is associated with a wide spectrum of delivery disorders, such as delayed or post-term delivery, that might be explained partly by the increase in plasma leptin levels in obese women, as leptin inhibits in vitro myometrial contractility. Delivery involves uterine apoptosis and remodelling of the extracellular matrix, via the activation of matrix metalloproteinases (MMP). This study was aimed to assess the role of leptin on human myometrium, by studying the interaction of leptin with lipopolysaccharide (LPS)-induced apoptosis and degradation of myometrial collagen.Myometrial biopsies were obtained from women undergoing caesarean delivery before labour onset. The effects of l…
Libri, incisioni e immagini di architettura come fonti per il progetto in Italia
2013
I saggi proposti in questo volume, elaborati nell’ambito del progetto Prin (2008) da studiosi dell’unità di Palermo e non, intendono affrontare il ruolo delle immagini (incisioni, stampe e disegni) nella prassi progettuale di eta' moderna e relazionare l’architettura costruita con i testi e le incisioni prodotti nell'ambito temporale considerato (XVI- XVIII secolo). Per gli architetti le incisioni costituiscono infatti una risorsa di suggestioni per articolare risposte convincenti alle richieste della committenza. L'analisi delle prassi costruttive ha fatto risaltare il ruolo assunto da una manualistica di settore classificata come raccolte di "porte e finestre". I contributi affrontano app…
