Lodovico Dolce tragediografo tra riscrittura dell'antico e traduzione
No full textLodovico Dolce between re-writing of the Ancient and translation
The present thesis consists in a precise and complete textual analysis of tragical production of Venetian playwright Lodovico Dolce (1508-1560), except his two last tragical works (Marianna and Troiane). Above all, I’ve studied well the first translation of the whole Senecan tragical corpus realized in a modern European language ever, published in Italian by Dolce in 1560 (Venezia, Sessa). Obviously, in the first chapter I’m concerned with the theory and practice of tragical poetry in Italy during the XVI century (in particular in the midst of the century), to contextualize the historical, political, anthropologi-cal, cultural position of Dolce and to underline what were his aesthetical ideas about the new tradition of tragical modern poetry. In the third chapter, I’m concerned with the various phenomenology of re-writing and translational theories and practices in the XVI century, with the goal to know what were the landmarks that Dolce chose for his theatrical texts, always result of a complex hypertextual activity, never original. The author, a poligrafo that was historic, comedian, satirical and epic poet, anthologist, translator, essayist, grammarian and editor and that asserted himself in the typographical world of Ve-nice, was also, although forced to work incredibly hard (and my research would show it) capable of do-ing authorial and autonomic literary choices, of finding personal dramatic and poetic strategies and of realizing a fundamental popularization of cultural contents (especially classical), otherwise not available for the majority of the people at that time
Distributing load flow computations across system operators boundaries using the Newton–Krylov–Schwarz algorithm implemented in PETSC
No full textThe upward trends in renewable energy penetration, cross-border flow volatility and electricity actors’ proliferation pose new challenges in the power system management. Electricity and market operators need to increase collaboration, also in terms of more frequent and detailed system analyses, so as to ensure adequate levels of quality and security of supply. This work proposes a novel distributed load flow solver enabling for better cross border flow analysis and fulfilling possible data ownership and confidentiality arrangements in place among the actors. The model exploits an Inexact Newton Method, the Newton–Krylov–Schwarz method, available in the portable, extensible toolkit for scientific computation (PETSc) libraries. A case-study illustrates a real application of the model for the TSO–TSO (transmission system operator) cross-border operation, analyzing the specific policy context and proposing a test case for a coordinated power flow simulation. The results show the feasibility of performing the distributed calculation remotely, keeping the overall simulation times only a few times slower than locally

Viene proposta l’attribuzione a Guido Reni di una piccola Deposizione di Cristo dipinta su rame, conservata in collezione privata e già proveniente dalla collezione di Luigi Grassi per donazione. Questa Deposizione appartiene a quella rara e preziosa tipologia di dipinti che non sono solo bozzetti preparatori, ma anche invenzioni tracciate dall’autore a ricordo dell’opera realizzata per il proprio uso personale. Questa Deposizione potrebbe essere uno studio per la Pietà dei Mendicanti di Bologna del 1613-1616.
ENGLISH ABSTRACT
The contribution proposes an attribution to Guido Reni for a small Deposition of Christ painted on copper and stored in a private collection, formerly in the collection of Luigi Grassi as a donation. This Deposition belongs to that rare and precious kind of paintings that are not only preparatory sketches, but can be regarded as inventions of the author, meant to remind him the painted work through a private fruition. This Deposition could be a study for the Mercy of the beggars in Bologna, dated 1613-1616
«Una vera e non museografica conversazione di monumenti e di ambienti»: Guido Di Stefano e l’«azione urbanistica» nella Palermo del secondo dopoguerra
No full textL' articolo indaga gli scritti, le attività didattiche e le reti culturali dell'arte e dell'architettura siciliana storico Guido Di Stefano (1906-62). Concentrandosi sui suoi viaggi in Germania e sui suoi contatti con colleghi austriaci (Dagobert Frey), tedeschi (Wolfgang Krönig) ed eminenti colleghi italiani (Carlo Ludovico Ragghianti), l'autore legge la battaglia solitaria di Di Stefano contro la speculazione e il vandalismo nel settore immobiliare a Palermo, nonché il suo coinvolgimento nel stesura del piano urbano dopo la seconda guerra mondiale come aspetti specifici di un'idea di civiltà e impegno politico le cui radici possono essere identificate nell'influente pensiero filosofico di Benedetto Croce.This article investigates the writings, teaching activities and cultural networks of the Sicilian art and architectural
historian Guido Di Stefano (1906-62). By focussing on his travels to Germany and his contacts to Austrian (Dagobert
Frey), German (Wolfgang Krönig) and eminent Italian colleagues (Carlo Ludovico Ragghianti), the author reads Di
Stefano’s solitary battle against real estate speculation and vandalism in Palermo as well as his involvement in the
drafting of the urban plan after World War II as specific facets of an idea of civilization and political commitment
whose roots can be identified in Benedetto Croce’s influential philosophical thaught
Destination Unknown. Is there any Economics Beyond Tourism Areas?
No full textIn recent years, several papers have been focussing on various aspects of tourism destinations. The destination is a central issue within tourism studies, embodying in one single concept all the specific and problematic features of tourism, such as its systemic nature in which "space" plays a fundamental role.
In this paper we argue that tourism economics shapes itself as an independent discipline within applied economics through the analysis of destinations. Firstly, destinations are neither microeconomic agents nor macroeconomic aggregates, but territorial systems which supply at least one tourism product (a bundle of goods and services) able to satisfy the complex needs of tourism demand.
Secondly, the economic analysis of destinations can identify two specific theorems, the love of variety theorem and the coordination theorem which allow to interpret the tourism destination as a particular type of economic district, which shares some of the features of the industrial district and some others of the cultural district.

Newton-Krylov-Schwarz method for distributed power flow modelling and related applications
No full textLAUREA MAGISTRALELa rete elettrica Europea è una delle più complesse al mondo. La sempre maggiore penetrazione delle energie rinnovabili stabilisce nuove sfide nella gestione delle reti elettriche, incentivando gli operatori di rete (TSOs) ad aumentare la collaborazione al fine di garantire il trasporto efficiente e affidabile di energia elettrica. I flussi inter-zonali sono perlopiù fissati e permettono solamente una limitata flessibilità nella gestione della rete. La condivisione delle informazioni tra TSOs è ancora un problema. Lo scopo di questo lavoro è stato di costruire un tool di calcolo distribuito per la risoluzione del problema di load flow, al fine di migliorare la gestione dei flussi interzonali e allo stesso tempo garantire privacy nelle informazioni. Il modello sfrutta un metodo di Newton inesatto, noto come Newton-Krylov-Schwarz, disponibile in una libreria di calcolo, PETSc.European Electricity grid is one of the most complex grids in the world. The increasing penetration of REnewable Energy Sources (RES) sets new challenges in grid management, stressing Transmission System Operators (TSOs) to increase collaboration so as to ensure high quality and reliable transportation of electricity. Cross-border flows are nearly fixed and only allow limited flexibility for grid management. Data privacy among TSOs is still an issue. The purpose of this work has been to build a Distributed Load Flow solver for better cross-border flow management while allowing for data privacy. The model exploits an Inexact Newton Method, the Newton-Krylov-Schwarz method, available in PETSc libraries
Effectiveness and Safety of Argon Plasma Coagulation in Patients with Haemoptysis Caused by an Endobronchial Malignancy
No full textIntroduction: Patients with central neoplasms and haemoptysis show low survival rates. Symptom control without recurrence 48 h after bronchoscopic interventions may improve the prognosis of these patients. Bronchoscopic argon plasma coagulation (APC) is a useful technique for endobronchial management of haemoptysis in patients with central malignancies. Nevertheless, limited data are available in the literature on its efficacy and safety and the main predictors of success are still unclear. Methods: An observational, prospective, single-centre cohort study was carried out to assess the efficacy (i.e., immediate bleeding cessation without recurrence during the following 48 h) of bronchoscopic APC in the treatment of patients with haemoptysis caused by endobronchial malignancies and the main predictors of success. Results: A total of 76 patients with median age 75 years (interquartile range: 65-79) were enrolled. 67 (88.2%) patients had bleeding cessation without recurrence 48 h after bronchoscopic APC. A low rate of non-serious adverse events (5.3%) was recorded and a low (7.6%) recurrence rate of haemoptysis at 3.5 months after the procedure was also shown. No clinical, demographic and endoscopic variables related to a successful procedure at 48 h were found. Conclusion: This study demonstrates that bronchoscopic APC is an effective procedure in the treatment of patients with haemoptysis caused by endobronchial malignancies, regardless of the clinical characteristics of the patients, the endoscopic and histological features of the neoplasm and the severity of the symptom. Furthermore, it shows a low rate of complications and long-term efficacy in bleeding control

Diagnosis, treatment, and follow-up of patients with cerebral amyloid angiopathy-related inflammation
No full textPurpose Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare potentially reversible encephalopathy associated with an autoimmune process against proteins deposited in the walls of cortical and leptomeningeal brain vessels. Definite diagnosis requires histopathological features of vascular inflammation and amyloid deposition from brain biopsy. Clinical-neuroradiological criteria have been recently introduced and validated to reduce the need for biopsy. The purpose of this paper is to report a historical retrospective review of clinical-neuroradiological follow-up of two patients with probable CAA-ri and five patients with a reasonably probable suspect of CAA-ri (4 females, 3 males, patient's age at admission: 66-79 years) seen at our institution between 2007 and 2021, focusing on clinical and neuroradiological awareness to this entity and variable response to immunotherapy. Materials and methods Clinical features at presentation included subacute to acute confusion (6/7), seizures (4/7), cognitive impairment (5/7), and focal neurological signs (3/7). Neuroradiology included braincomputed tomography followed by magnetic resonance imaging. Infectious diseases and autoimmune workups were then performed. Results CSF analysis was performed in two patients. Cerebral angiography was performed in two patients, to rule out vascular malformations. Hemorrhagic posterior reversible encephalopathy syndrome has been suspected in two patients. Four patients underwent immunotherapy with corticosteroids followed by reduction of brain dysfunctions. Three patients did not undergo immunotherapy but underwent clinical and/or neuroradiological remission. Conclusions Patients with CAA-ri present a rare steroid-responsive acute to subacute brain dysfunction. Thus, it has to be known and recognized both clinically and neuroradiologically. Spontaneous clinical and/or neuroradiological improvement is possible in patients with mild symptoms. © 2022, The Author(s)
