"Look here upon this picture": Il quadro sulla scena elisabettiana
No full textQuesto saggio discute l'utilizzo, da parte di Shakespeare, del quadro come oggetto scenico, nel contesto del dibattito epocale sulle arti visive, e con particolare riferimento alla prassi e teoria pittorica di Nicholas Hillyar
'Stuff to make paradoxes': Shakespeare e i paradossi tragici del 'sembra'.
No full textIl saggio discute problemi inerenti la pregnanza tragica e situazionale di alcune figure della contraddizione nel teatro shakespeariano, individuando gli aspetti che rendono paradossali in chiave logica contrari e contraddittori a seconda del contesto drammatico e della illocutorietà, di contro a una retorica intenzionalmente imperniata sulla contestazione del codice (culturale e linguistico). Particolare attenzione viene dedicata alle tragedie di Amleto e di Otello

No full textRenewable building blocks for sustainable polyesters: new biotechnological routes for greener plastics
No full textThe next generation of plastics are expected to contribute to a massive reduction in the carbon footprint by the exploitation, in industrial productive processes, of renewablemonomers such as polyols and dicarboxylic acids obtainable via biotechnological production. More specifically, there is a rising demand for advanced polyesters displaying new functional properties while
meeting higher sustainability criteria. Polyesters are part of everyday life with applications in clothing, food packaging, car manufacturing and biomedical devices. This reviewis intended to provide an overviewof the array of renewable building blocks already available for synthetic purposes and exploitable in the production of polyesters. Moreover, newgreener routes formore
environmentally friendly polyester production and processing are discussed, pointing out the major technological challenges
High frequency percussive ventilation (HFPV). Principles and technique.
No full textIn recent years, the usefulness of high frequency ventilation (HFV) has been clinically reassessed as an alternative to conventional mechanical ventilation (CMV). HFV has often been combined with or in some cases even completely replaced CMV in the attempt to reduce iatrogenic injury. High frequency percussive ventilation (HFPV) is a specific mode of HFV that has been successfully applied in the treatment of acute respiratory failure after smoke inhalation; it has also been more widely used in pediatric than in adult patients. This article gives an introduction to and a description of the basic principles of HFPV, a mode of ventilation which we found particularly versatile and reliable in our preliminary clinical experience with the maneuver
Machine Learning-Based Monitoring for Planning Climate-Resilient Conservation of Built Heritage
No full textThe increasing frequency and intensity of extreme weather events are accelerating the mechanisms of surface degradation of heritage buildings, and it is therefore appropriate to find automatic techniques to reduce the time and cost of monitoring and to support their planned conservation. A fully automated approach is presented here for the segmentation and classification of the architectural elements that make up one of the façades of Palazzo Pitti. The aim of this analysis is to provide tools for a more detailed assessment of the risk of detachment of parts of the pietraforte sandstone elements. Machine learning techniques were applied for the segmentation and classification of information from a DEM obtained via a photogrammetric drone survey. An unsupervised geometry-based classification of the segmented objects was performed using K-means for identifying the most vulnerable elements according to their shapes. The results were validated through comparing them with those obtained via manual segmentation and classification, as well as with studies carried out by experts in the field. The initial results, which can be integrated with non-geometric information, show the usefulness of drone surveys in the context of automatic monitoring of heritage buildings
