Norme Tecniche per le Costruzioni: rivalutazione dei coefficienti di amplificazione stratigrafica da analisi di risposta sismica locale su depositi ideali
Le Norme Tecniche per le Costruzioni (NTC) tengono conto, nella determinazione delle azioni
sismiche mediante il metodo semplificato, degli effetti di amplificazione del moto mediante coefficienti di
amplificazione stratigrafica Ss, funzione della categoria di sottosuolo e del livello di non linearità raggiunto dai
terreni. L’attendibilità di tali coefficienti è stata valutata, nel presente lavoro, mediante il confronto con i risultati
di 2400 analisi di risposta sismica locale monodimensionale che hanno esplorato parametricamente vari profili di
sottosuolo e livelli di intensità del moto sismico applicato. I risultati preliminari mostrano che per le classi di
sottosuolo B e C gli Ss delle NTC sono in sostanziale accordo con i risultati numerici ad eccezione di una leggera
sottostima a bassi livelli di intensità del moto sismico. Per le classi di sottosuolo D e E il confronto mostra
maggiori discrepanze: l’amplificazione stratigrafica fornita dalle NTC sembra essere sensibilmente sovrastimata
per la classe D e sottostimata per la classe E. Ulteriori analisi sono in corso per esplorare quest’ultimo aspett
Schermi. Immagini, corpi, condivisioni
In this book the author investigates the digital image proliferation of our times from an interdisciplinary point of view. Starting from the Visual Culture theoretical frame, Valentina Mignano explores the ways in which we interact with the screen, dealing with the "screen experience" in the first years of the network societ
Delamination on GFRP laminates impacted at room and lower temperatures: Comparison between epoxy and vinylester resins
Low velocity impact tests at three different impact energy values and three different temperatures, were performed on glass fibre composite laminates made by infusion technology. Two different resins, epoxy and vinylester, were considered to impregnate the fibres: the first is mainly of aeronautical interest whereas the second one is mainly applied in Naval field. The specimens were first completely destroyed to obtain the complete load-displacement curve. The latter allowed the evaluation of the increasing impact energies, 5, 10 and 20J, used to investigate about the start and propagation of the damage inside the laminates. The delamination was investigated by the very commonly used Ultra Sound technique and the results obtained on the different materials at different temperatures were compared. A general better behaviour of vinylester resin was noted. © 2016 Author(s)

Residual strength evaluation after impact tests in extreme temperature conditions. New equipment for CAI tests
A large experimental campaign has included low velocity falling weight tests at room and low temperatures, on carbon fibre laminates in vinylester resin, clamped following the EN6038 or ASTMD7136 Standards, or simply supported by a water pillow. The latter clamping device was used to differently distribute the load and to investigate about the influence of the water backing. The mechanics-based understanding of the fluid-structure interaction occurring during the impact, was devoted to understand the role of water-backing on the loading experienced by the panel, toward informing the interpretation of empirical observations and design of new experiments. Non destructive and destructive evaluations for damage investigations were carried out whereas the design and the production of a new, more simple and reliable Compression After Impact (CAI) apparatus, was described and adopted to avoid errors due to misalignment between the applied load and the specimen. CAI tests were then, performed to evaluate the residual compression strength. Analytical and semi empirical models were evaluated and validated to predict the influence of the geometric parameters on the impact behaviour of the laminates. The final aim was to predict the impact energy, delamination and residual strength, in the different test conditions. © 2017 Elsevier Lt

La tutela della salute pubblica: i delitti alimentari e le altre fattispecie annesse
La trattazione ha lo scopo di analizzare gli elementi che compongono i reati di cui agli artt. 439, 440, 441 c.p., fornendo un quadro completo delle fattispecie e mettendo in luce i relativi aspetti dogmatici, nonché le problematiche interpretative riscontrate in materia di delitti alimentari.
Al riguardo, il commento non può fare a meno di prendere in esame le posizioni as-sunte dalla giurisprudenza su questioni ermeneutiche cruciali per la definizione dell’ambito applicativo delle fattispecie. In particolare, si faccia riferimento non solo ai dubbi scaturiti dalla loro qualificazione in reati di pericolo, ma altresì alle perplessità sollevate in ordine ai limiti imposti dall’oggetto materiale delle condotte, componente distintiva e di fondamentale importanza per i delitti di cui si discute
Dynamic load on composite laminates in the presence of water
An experimental activity, in order to assess the impact behavior at room and low temperature, of carbon fiber in vinylester resin laminates used in the shipbuilding industry, was conducted. The conditions, which simulate the impact of a tool that drop on the panel mounted on a boat hull in contact with water, were reproduced. This is a condition named water backing, in the middle between the pure impact (air backing) and the hull slamming, and not already tested before. An innovative equipment was designed and realized at University of Naples "Federico II," to reproduce the real dynamic material behavior in the presence of water, at the aim to investigate the influence of the water backed on the response of laminates under impact conditions. The results were obtained impacting the laminates placed between the cylindrical steel impactor and a bag containing water. A falling weight machine, equipped with a thermal chamber, was adopted for the experimental tests. The simulated test condition is completely new since no similar research is possible to find in literature. The impact behavior in hostile environments was compared to the room conditions, and the data obtained by the water backed loading tests were compared with the results by the pure impact tests. In the latter case, a completely different behavior was observed between the two different loading conditions, in terms of both load-displacement curve and the internal damage. The effect of the impact load on the laminates has been analyzed through the delamination and the indentation
