Validazione di modelli macrosismici per la stima del danneggiamento
No full textI metodi macrosismici per la stima del danneggiamento di edifici residenziali sono stati inizialmente sviluppati ed utilizzati per la realizzazione di scenari di rischio all’interno di importanti progetti nazionali per l’area di Vittorio Veneto (Bernardini et al., 2008; Meroni et al., 2008a, 2008b) e la Liguria occidentale (Giovinazzi e Lagomarsino, 2004). Grazie alla loro robustezza e flessibilità hanno successivamente avuto ampia diffusione anche a livello Europeo nei progetti Risk-UE (Mouroux and Le Brun, 2006; Lantada et al., 2010), LessLoss (Spence, 2007), UPStrat-MAFA (2012), Syner-G (2012), Zonno et al. (2010).
Attualmente sono disponibili in letteratura diversi metodi, che si differenziano principalmente nella definizione della vulnerabilità delle strutture, ma la cui formulazione originaria parte dalla definizione del danno macrosismico secondo la scala EMS98 (Grünthal, 1998).
Nonostante la loro diffusione questi metodi mancano ancora di una esaustiva validazione. La disponibilità di un rilievo macrosismico dettagliato per il centro storico de L’Aquila (Tertulliani et al., 2011, 2012) ha permesso di confrontare i risultati di alcune stime di danneggiamento macrosismico con una situazione reale, pur con alcune limitazioni dettate dalla tipologia dell’edificato in questione e dall’analisi estesa al solo grado di intensità registrato IEMS98 = VIII-IX.PublishedBologna, Italia3T.

Gruppi con pochi sottogruppi non quasinormali
No full textLet be a group. A subgroup of is said to be quasinormal if for every subgroup of , and is called quasi-Hamiltonian if all its subgroups are quasinormal. The structure of quasi-Hamiltonian groups has been described by {\it K. Iwasawa} [in J. Fac. Sci., Univ. Tokyo, Sect. I 4, 171-199 (1941; Zbl 0061.025) and Jap. J. Math. 18, 709-728 (1943; Zbl 0061.025)]. If is a group, let denote the subgroup generated by all subgroups of which are not quasinormal. Then is quasi-Hamiltonian if and only if , and it is easy to show that is generated by all cyclic non-quasinormal subgroups of .\par The author studies the class of all groups for which is a proper subgroup. The corresponding problem for the subgroup generated by all non-normal subgroups was considered by {\it D. Cappitt} [J. Algebra 17, 310-316 (1971; Zbl 0232.20067)]. Clearly every -group is generated by cyclic quasinormal subgroups, and in particular it is locally nilpotent. The author proves that non-periodic -groups are quasi-Hamiltonian. The investigation of periodic -groups can be reduced to the case of a -group ( prime), and the description of -groups in the class is obtained. In particular, it is shown that a -group of infinite exponent is in the class if and only if the subgroup generated by all non-normal subgroups of is properly contained in . Finally, the author proves that if is an -group whose Sylow 2-subgroup is quasi-Hamiltonian, then is metabelian.

A Simple Proof of Baer's and Sato's Theorems on Lattice Isomorphisms between Groups
No full textA group is said to be an M\sp*-group if all subgroups of are quasinormal and is quaternionfree. Using Iwasawa's characterization of M\sp*-groups the author gives an elegant and unified proof of the following theorem: If is an M\sp*-group, then there exists an abelian group such that the lattices of subgroups of and are isomorphic.

Mario Botta e la nuova chiesa parrocchiale di Sambuceto
No full textIl 3 febbraio 2007 Mario Botta ha presentato a Pescara, nella Facoltà di Architettura dell'Università "d'Annunzio", il progetto di fattibilità per la nuova chiesa parrocchiale di S. Rocco a Sambuceto. Il tema progettuale relativo agli edifici sacri ha occupato gran parte dell'ultima produzione di Mario Botta, che, come ribadito a Pescara, è arrivato al Sacro progettando chiese ma anche una sinagoga ed un moschea, trovando le ragioni più profonde dell’architettura tout court. In quell’occasione l’autore ha incontrato il maestro ticinese trattando alcuni grandi temi della sua carriera e dell’architettura internazionale non solo contemporanea. La pubblicazione ripercorre le tappe più salienti del rapporto tra Botta e la progettazione di nuove chiese, per stringere la focale sull’episodio di Sambuceto, che ha interessato anche un difficile confronto con la precedente chiesa progettata e realizzata da Paride Pozzi, uno dei protagonisti dell’architettura del Novecento abruzzese. Chiude il volume l’intervista vera e propria, condotta dall’autore e consistente su cinque domande tematiche concernenti il rapporto tra l’architetto e la religione, l’eredità nel territorio dei grani lombardi dei secoli scorsi, la tipologia dello spazio sacro e le possibilità, oggi, della didattica di architettura.
On February 3, 2007 Mario Botta presented the feasibility study for the new parish church of St. Rocco, Sambuceto in the Faculty of Architecture at the University of "D'Annunzio", Pescara. The design theme related to the sacred buildings has occupied much of Mario Botta’s latest production whom, as reconfirmed in Pescara, arrived at Sacred buildings designing churches, but also a synagogue and a mosque, rapidly finding the underlying philosophy of architecture. On that occasion the author met the maestro Ticino and dealt with some of greatest subjects of his career, not only contemporary international architecture. The publication traces the phases of the relationship between Botta and the design of new churches, to increase the focus on Sambuceto which involved a difficult comparison between the previous church designed and built by Paride Pozzi, one of the key protagonists of twentieth century architecture in Abruzzo. The book ends with the interview itself, conducted by the author consisting of five questions and issues concerning the relationship between the architect and religion, the legacy of the region of Lombard grain in past centuries, types of sacred space and the opportunities today, in architectural teaching
Tragedia umana o nave fantasma? Aspetti antimimetici nell’Angelo del Liponard di Mario Tobino
No full textThe essay offers an analysis of Mario Tobino’s L’Angelo del Liponard, aimed at emphasizing some of its thematic and narrative aspects that refer to an antimimetic representation of reality. Beyond the attention to psychological introspection and uncovered autobiography, the work of the author from Viareggio always remains anchored to a realistic description of environments, situations, events. Yet, in the
Angelo del Liponard, it is possible to identify several incursions of the fantastic. The interpretative tools of textual criticism and semiotics are adopted
'The Conscious Corporate Growth Strategic Approach and Its Implementation'
No full textThis book addresses the question: how can institutions develop and maintain a good purpose? And how can managers contribute to this endeavour? Twelve contributions explore this question, using MacIntyrean inquiry as a basis for exploring four main themes: Can management be considered a practice in the MacIntyrean sense? What is the role of specific virtues in the development of a virtuous institution? What are management vices and what are the conditions in which they flourish? And, can we use MacIntyrean ideas to consider the management of all forms of institutions? The volume is an international and multidisciplinary collection, with contributions from well-known writers in the field of management ethics, and innovative contributions that use MacIntyrean inquiry as a lens to examine fields such as hospitality, user generated music content and social sustainability. The papers are unified by their concern for the achievement of organizational excellence and integrity through ethical management.Unlike single author texts this edited volume brings together multiple perspectives on the topic of virtue ethics in management. In doing so, it explores the topic both more deeply and more widely than a single author can do
Two-step tumour targetting in ovarian cancer patients using biotinylated monoclonal antibodies and radioactive streptavidin
No full textA new method for intraperitoneal tumour targetting in ovarian cancer using biotinylated monoclonal antibodies (MoAb) and radioactive streptavidin is described. Fifteen patients with histologically documented ovarian carcinoma were injected intraperitoneally with 2 mg of biotinylated MoAb MOv18, followed 3-5 days later by 100-150 Î1⁄4g of indium-111 streptavidin, at the specific activity of 280-370 MBq/mg in 500 ml of normal saline. No toxicity was observed. Tumours were imaged from 2 to 48 h after radioactivity injection by recording both planar and single photon emission tomography (SPET) data. All patients underwent surgery 1-8 days later (mean 3 days) after scanning. The resected tumour and normal tissue radioactivity were measured. On the day of surgery, the tumour to normal tissue ratio was 9:1 (range 3:1-30:1) and 45:1 (range 12:1-120:1) for intra- and extraperitoneal samples, respectively. The mean tumor to blood ratio was 14:1 (range 4:1-30:1). The injected dose (i.d.) per gram of tumour was 0.112 (range 0.01-0.3) for recurrences and 0.05 for primary tumour (range 0.005-0.2). Over 24-48 h 14% i.d. (range 8-18% i.d.) was found in the urine, 14% i.d. (range 629% i.d.) in the blood and 63% i.d. (range 56-70% i.d.) was still in the peritoneal cavity. These preliminary clinical data suggest that this two-step strategy may be superior to the conventional approach (radiolabelled antibodies) for intraperitoneal radioimmunolocalization and radioimmunotherapy of ovarian cancer. © 1992 Springer-Verlag
