Il Progetto ATENA: Applicazione di metodologie innovative per la conservazione di manufatti metallici e ceramici da scavo archeologico e per il recup…
2007
Qui di seguito viene illustrato il progetto scientifico ATENA, svolto presso l'Istituto per lo Studio dei Materiali Nanostrutturati (ISMN) del Consiglio Nazionale delle Ricerche (CNR) e co-finanziato dal MIUR con Decreto Direttoriale 9-10-2002, n. 1105/2002. Il progetto si propone di applicare avanzate tecniche diagnostiche strumentali al fine di acquisire la dettagliata conoscenza microchimica e microstrutturale di manufatti metallici e ceramici antichi, di definirne il meccanismo di alterazione e/o degrado e di progettare, sintetizzare e validare opportuni prodotti e formulazioni per il restauro conservativo di tali manufatti. Le conoscenze acquisite sono utilizzabili anche per il recuper…

2013
Il poster 1 è dedicato alla Metodologia T.R.U.E., che persegue l'obiettivo di supportare la progettazione del restauro, con particolare riferimento alla conservazione delle superfici di finitura e nel rispetto del valore di autenticità materiale delle architetture storiche. Poster number 1 is dedicated to the T.R.U.E. Methodology, that pursues the finality to elaborate the project for the conservation of the architectural surfaces and, in general, the respect of the authenticity of the materials stratified on the monumental architectures.
Indagini diagnostiche sui “Vasi di Centuripe” del Museo Archeologico Regionale “A. Salinas” di Palermo
2020
In questa saggio si intende presentare i risultati delle indagini diagnostiche eseguite in situ sui vasi centuripini conservati presso il Museo Archeologico Regionale “A. Salinas” di Palermo. Le indagini, condotte nell’ottica della multidisciplinarità insieme ad archeologi e restauratori, sono state applicate per step via via più approfonditi a partire dalle tecniche globali di immaging con luce visibile ed UV per lo studio della superfice, proseguendo con quelle puntuali di spettroscopia XRF ed FT-IR per lo studio dei pigmenti, del legante e dello strato di preparazione. In this essay we intend to present the results of the diagnostic investigations carried out in situ on the centuripine v…
Physics, Techniques and Review of Neuroradiological Applications of Diffusion Kurtosis Imaging (DKI)
2016
In recent years many papers about diagnostic applications of diffusion tensor imaging (DTI) have been published. This is because DTI allows to evaluate in vivo and in a non-invasive way the process of diffusion of water molecules in biological tissues. However, the simplified description of the diffusion process assumed in DTI does not permit to completely map the complex underlying cellular components and structures, which hinder and restrict the diffusion of water molecules. These limitations can be partially overcome by means of diffusion kurtosis imaging (DKI). The aim of this paper is the description of the theory of DKI, a new topic of growing interest in radiology. DKI is a higher or…
Specific Heat and Transport Functions of Water
2020
Numerous water characteristics are essentially ascribed to its peculiarity to form stronghydrogen bonds that become progressively more stable on decreasing the temperature. However, thestructural and dynamical implications of the molecular rearrangement are still subject of debate andintense studies. In this work, we observe that the thermodynamic characteristics of liquid water arestrictly connected to its dynamic characteristics. In particular, we compare the thermal behaviourof the isobaric specific heat of water, measured in different confinement conditions at atmosphericpressure (and evaluated by means of theoretical studies) with its configurational contribution obtainedfrom the value…
Performance of a new real time digital pulse processing system for X-ray and gamma ray semiconductor detectors
2014
New generation spectroscopy systems have advanced towards digital pulse processing (DPP) approaches. DPP systems, based on direct digitizing and processing of detector signals, have recently been favoured over analog pulse processing electronics, ensuring better performance. In this work, we present the performance of a new real time DPP system for X-ray and gamma ray semiconductor detectors. The system is based on a commercial digitizer equipped with a custom DPP firmware, developed by our group, for on-line pulse shape and height analysis. X-ray and gamma ray spectra measurements with cadmium telluride (CdTe) and germanium (Ge) detectors, coupled to resistive feedback preamplifiers, will …
Digital Techniques for High-Rate High-Resolution Radiation Measurements
2014
Digital pulse processing (DPP) techniques are increasingly used in the development of modern spectroscopic systems. DPP systems, based on direct digitizing and processing of detector signals (preamplifier output signals), ensure higher flexibility, stability, lower dead time, higher throughput and better energy resolution than traditional pulse processing systems. In this work, we present our progress in the development of DPP systems for high-rate high-resolution radiation measurements. An innovative digital system, able to perform multi-parameter analysis (input counting rate, pulse height, pulse shape, event arrival time, etc.) even at high photon counting rates is presented. Experimenta…
La rappresentazione digitale per l’accessibilità al patrimonio culturale
2021
Da diversi anni, la rappresentazione digitale ha assunto un ruolo fondamentale nel campo della valorizzazione del patrimonio culturale, introducendo nuove modalità operative. Allo stesso tempo e con frequenza sempre maggiore siti monumentali, musei e istituzioni culturali si avvalgono di applicazioni e installazioni che, grazie all’impiego di tecnologie di uso comune, adoperano il linguaggio multimediale per consentire l’accessibilità virtuale ai Beni Culturali. Questo contributo racconta brevemente alcuni esempi di approcci e applicazioni pensati per assicurare accessibilità tattile, sonora o virtuale a un’utenza ampia e variegata. Sono qui analizzati approcci differenti che favoriscono il…
Aqueous Processed Biopolymer Interfaces for Single-Cell Microarrays
2020
Single-cell microarrays are emerging tools to unravel intrinsic diversity within complex cell populations, opening up new approaches for the in-depth understanding of highly relevant diseases. However, most of the current methods for their fabrication are based on cumbersome patterning approaches, employing organic solvents and/or expensive materials. Here, we demonstrate an unprecedented green-chemistry strategy to produce single-cell capture biochips onto glass surfaces by all-aqueous inkjet printing. At first, a chitosan film is easily inkjet printed and immobilized onto hydroxyl-rich glass surfaces by electrostatic immobilization. In turn, poly(ethylene glycol) diglycidyl ether is graft…
An empirically grounded agent based model for modeling directs, conflict detection and resolution operations in air traffic management
2017
We present an agent based model of the Air Traffic Management socio-technical complex system that aims at modeling the interactions between aircrafts and air traffic controllers at a tactical level. The core of the model is given by the conflict detection and resolution module and by the directs module. Directs are flight shortcuts that are given by air controllers to speed up the passage of an aircraft within a certain airspace and therefore to facilitate airline operations. Conflicts resolution between flight trajectories can arise during the en-route phase of each flight due to both not detailed flight trajectory planning or unforeseen events that perturb the planned flight plan. Our mod…
