Capitolo 5b: Disfunzione endoteliale e biomarkers nelle malattie vascolari
No full textLe malattie vascolari rappresentano attualmente la prima causa di morte nel mondo e i percorsi diagnostico-terapeutici e preventivi per cercare di combatterle sono in continua evoluzione. Tuttavia, nella corrente bibliografia non è ancora presente una guida scientifica comune che abbracci e tratti contemporaneamente l'intero panorama delle malattie arteriose, venose e dei vasi linfatici dell'adulto e del bambino. Tutto ciò, sia dal punto di vista dell'aggiornamento scientifico per i Medici Specialisti che gestiscono pazienti con malattie vascolari nella loro pratica clinica quotidiana e che intendono approfondire particolari aspetti di tali patologie, sia dal punto di vista didattico, ovvero per i giovani studenti di Medicina e per i Medici Specializzandi in fase di perfezionamento in tali patologie.
Il Trattato di Medicina Vascolare a cura del Dr. Giuseppe Camporese, del Prof. Paolo Simioni e del Dr. Enrico Bernardi ha l'ambizione di colmare questo vuoto, grazie alla collaborazione di più di 160 Autori di rilievo nazionale ed internazionale, per buona parte - ma non solo - esponenti della Scuola di Medicina dell'Università di Padova e dell'Azienda Ospedaliera di Padova

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Topographic correction of HiRISE and CaSSIS images: Validation and application to color observations of Martian albedo features
No full textThe topographic correction of satellite images has to be applied to both disentangle albedo features from illumination effects induced by local topography and performspectrophotometric analyses of planetary surfaces. This work focuses on the modeling and removal of surface brightness variations induced by topography, referred astopographic shading, from high resolution images of Mars. Topographic shading can be modeled through functions of the surface illumination and observation anglescalled disk functions. We consider four disk functions that are widely used in planetary photometry: the Lambert, Lommel-Seeliger, Akimov and Minnaert diskfunctions. We test and evaluate their performances in removing topographic shading from High Resolution Imaging Science Experiment (HiRISE) and Colour andSurface Science Imaging System (CaSSIS) images. We here validate our method, moreover, we report scientific applications to single or multi-band datasets byanalyzing topographically corrected HiRISE colour observations of Martian recurring slope lineae and dust devil tracks, as well as CaSSIS panchromatic observations
Three-dimensional modeling using x-ray shape-from-silhouette,
No full textWe present the application of the shape-from-silhouette technique to reconstruct the three-dimensional profile of ancient handworks from their x-ray absorption images. The acquisition technique is similar to tomography, since the images are taken all around the object while it is rotated. Some reference points are placed on a small and light structure corotating with the object, and are acquired on the images for calibration and registration. The reconstruction algorithm gives finally the three-dimensional appearance of the handwork. We present the analysis of a bronze pendant of VT-VII century B.C. (Venetic area, Italy) completely hidden by corrosion products. The three-dimensional reconstruction shows that the pendant is a very elaborated piece, with two embraced figures that were completely invisible at the excavation.
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Piazzale Stanga e via Venezia.
No full textIl capitolo qui presentato, oltre al testo, raccoglie gli elaborati e i disegni per il progetto urbano per l’area di Piazzale Stanga e Via Venezia a Padova. È essenzialmente un progetto di ricerca sui temi della riqualificazione urbana, con il quale si è cercato di dare forma a questo luogo attraverso l’architettura tentando di costruire per frammenti, nelle aree disponibili alla trasformazione, luoghi e architetture che vorrebbero essere significativi, interpretando il tema della porta urbana nella sua possibile attualità. Un tema “necessario” nel processo di ricostruzione delle periferie, delle città giovani, figurativamente deboli, alle quali manca ancora quel processo di sedimentazione e stratificazione che solo il tempo può imprimere e che caratterizza le città storiche.
Il contributo progettuale qui presentato è il frutto del "Workshop internazionale di architettura. Padova 2013" tenuto al Palazzo della Gran Guardia a Padova e in mostra dal 19 settembre al 13 ottobre 2013, ideato e promosso da "Di Architetura Associazione Culturale" e dal Comune di Padova - Assessorato all'urbanistica. A partecipare al workshop sono stati invitati sei architetti internazionali: Jan Kleihues, Antonio Monestiroli, Uwe Schröder, Guillermo Vàzquez Consuegra, Gino Malacarne, Carlo Magnani, a cui sono state affidate sei diverse aree studio della città di Padova per cui proporre nuove idee progettuali
