No full textValidazione di una procedura numerica per l’analisi di interazione dinamica terreno-fondazione-struttura di telai in acciaio
No full textLa risposta sismica di una struttura è il risultato di complessi fenomeni di mutua interazione che avvengono tra tre sistemi interconnessi: terreno di fondazione, struttura di fondazione e sovrastruttura.
La presente nota illustra, con riferimento a due differenti tipologie strutturali in acciaio, la validazione di una procedura di simulazione numerica dell’interazione dinamica terreno-fondazione-struttura, attraverso l’implementazione del cosiddetto metodo diretto, il quale prevede un unico modello che include il terreno, la fondazione e la sovrastruttura.
La procedura numerica è validata mediante la riproduzione di risultati di prove su tavola vibrante, utilizzando il programma di calcolo alle differenze finite FLAC2D. La modellazione del sottosuolo è implementata con elementi a comportamento isteretico non lineare e criterio di rottura alla Mohr-Coulomb. Le fondazioni, superficiali e profonde, sono modellate come elementi a comportamento elastico e sono connesse al terreno mediante l’utilizzo di elementi di interfaccia. La sovrastruttura è costituita da due tipologie strutturali in acciaio, caratterizzate da diverso comportamento dissipativo non lineare e tipologia di fondazione: struttura intelaiata (MRF) e struttura a controventi concentrici (CBF)

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

No full textChest wall reconstruction with a novel titanium mesh after partial sternectomy for chondrosarcoma
No full textPrimitive malignant sternal tumours are extremely rare and represent less than 1% of all chest wall tumours. A combination of radical surgery and accurate reconstruction is mandatory to ensure adequate stability and to reduce paradoxical movement. To date, this is one of the few reports on a successful sternal reconstruction using a rigid titanium mesh to restore the skeletal integrity, which was then covered by bilateral muscular flaps
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
