Numerical simulations of magma chamber dynamics at Campi Flegrei, and associated seismicity, deformation and gravity changes

Understanding the complex relationships between quantities measured by volcanic monitoring network and shallow magma processes is a crucial headway for the comprehension of volcanic processes and a more realistic evaluation of the associated hazard. This question is very relevant at Campi Flegrei, a volcanic quiescent caldera immediately north-west of Napoli (Italy). The system activity shows a high fumarole release and periodic ground slow movement (bradyseism) with high seismicity. This activity, with the high people density and the presence of military and industrial buildings, makes Campi Flegrei one of the areas with higher volcanic hazard in the world. In such a context my thesis has been focused on magma dynamics due to the refilling of shallow magma chambers, and on the geophysical signals detectable by seismic, deformative and gravimetric monitoring networks that are associated with this phenomenologies. Indeed, the refilling of magma chambers is a process frequently occurring just before a volcanic eruption; therefore, the faculty of identifying this dynamics by means of recorded signal analysis is important to evaluate the short term volcanic hazard. The space-time evolution of dynamics due to injection of new magma in the magma chamber has been studied performing numerical simulations with, and implementing additional features in, the code GALES (Longo et al., 2006), recently developed and still on the upgrade at the Istituto Nazionale di Geofisica e Vulcanologia in Pisa (Italy). GALES is a finite element code based on a physico-mathematical two dimensional, transient model able to treat fluids as multiphase homogeneous mixtures, compressible to incompressible. The fundamental equations of mass, momentum and energy balance are discretised both in time and space using the Galerkin Least-Squares and discontinuity-capturing stabilisation technique. The physical properties of the mixture are computed as a function of local conditions of magma composition, pressure and temperature.The model features enable to study a broad range of phenomenologies characterizing pre and sin-eruptive magma dynamics in a wide domain from the volcanic crater to deep magma feeding zones. The study of displacement field associated with the simulated fluid dynamics has been carried out with a numerical code developed by the Geophysical group at the University College Dublin (O’Brien and Bean, 2004b), with whom we started a very profitable collaboration. In this code, the seismic wave propagation in heterogeneous media with free surface (e.g. the Earth’s surface) is simulated using a discrete elastic lattice where particle interactions are controlled by the Hooke’s law. This method allows to consider medium heterogeneities and complex topography. The initial and boundary conditions for the simulations have been defined within a coordinate project (INGV-DPC 2004-06 V3_2 “Research on active volcanoes, precursors, scenarios, hazard and risk - Campi Flegrei”), to which this thesis contributes, and many researchers experienced on Campi Flegrei in volcanological, seismic, petrological, geochemical fields, etc. collaborate. Numerical simulations of magma and rock dynamis have been coupled as described in the thesis. The first part of the thesis consists of a parametric study aimed at understanding the eect of the presence in magma of carbon dioxide in magma in the convection dynamics. Indeed, the presence of this volatile was relevant in many Campi Flegrei eruptions, including some eruptions commonly considered as reference for a future activity of this volcano. A set of simulations considering an elliptical magma chamber, compositionally uniform, refilled from below by a magma with volatile content equal or dierent from that of the resident magma has been performed. To do this, a multicomponent non-ideal magma saturation model (Papale et al., 2006) that considers the simultaneous presence of CO2 and H2O, has been implemented in GALES. Results show that the presence of CO2 in the incoming magma increases its buoyancy force promoting convection ad mixing. The simulated dynamics produce pressure transients with frequency and amplitude in the sensitivity range of modern geophysical monitoring networks such as the one installed at Campi Flegrei . In the second part, simulations more related with the Campi Flegrei volcanic system have been performed. The simulated system has been defined on the basis of conditions consistent with the bulk of knowledge of Campi Flegrei and in particular of the Agnano-Monte Spina eruption (4100 B.P.), commonly considered as reference for a future high intensity eruption in this area. The magmatic system has been modelled as a long dyke refilling a small shallow magma chamber; magmas with trachytic and phonolitic composition and variable volatile content of H2O and CO2 have been considered. The simulations have been carried out changing the condition of magma injection, the system configuration (magma chamber geometry, dyke size) and the resident and refilling magma composition and volatile content, in order to study the influence of these factors on the simulated dynamics. Simulation results allow to follow each step of the gas-rich magma ascent in the denser magma, highlighting the details of magma convection and mixing. In particular, the presence of more CO2 in the deep magma results in more ecient and faster dynamics. Through this simulations the variation of the gravimetric field has been determined. Afterward, the space-time distribution of stress resulting from numerical simulations have been used as boundary conditions for the simulations of the displacement field imposed by the magmatic dynamics on rocks. The properties of the simulated domain (rock density, P and S wave velocities) have been based on data from literature on active and passive tomographic experiments, obtained through a collaboration with A. Zollo at the Dept. of Physics of the Federici II Univeristy in Napoli. The elasto-dynamics simulations allow to determine the variations of the space-time distribution of deformation and the seismic signal associated with the studied magmatic dynamics. In particular, results show that these dynamics induce deformations similar to those measured at Campi Flegrei and seismic signals with energies concentrated on the typical frequency bands observed in volcanic areas. The present work shows that an approach based on the solution of equations describing the physics of processes within a magmatic fluid and the surrounding rock system is able to recognise and describe the relationships between geophysical signals detectable on the surface and deep magma dynamics. Therefore, the results suggest that the combined study of geophysical data and informations from numerical simulations can allow in a near future a more ecient evaluation of the short term volcanic hazard.

Atmospheric corrosion of quaternary bronzes (Cu-Sn-Zn-Pb): laboratory tests (accelerated ageing in wet & dry conditions)and field studies (the Bottego monument in Parma, Italy).

The interactions between outdoor bronzes and the environment, which lead to bronze corrosion, require a better understanding in order to design effective conservation strategies in the Cultural Heritage field. In the present work, investigations on real patinas of the outdoor monument to Vittorio Bottego (Parma, Italy) and laboratory studies on accelerated corrosion testing of inhibited (by silane-based films, with and without ceria nanoparticles) and non-inhibited quaternary bronzes are reported and discussed. In particular, a wet&dry ageing method was used both for testing the efficiency of the inhibitor and for patinating bronze coupons before applying the inhibitor. A wide range of spectroscopic techniques has been used, for characterizing the core metal (SEM+EDS, XRF, AAS), the corroded surfaces (SEM+EDS, portable XRF, micro-Raman, ATR-IR, Py-GC-MS) and the ageing solutions (AAS). The main conclusions were: 1. The investigations on the Bottego monument confirmed the differentiation of the corrosion products as a function of the exposure geometry, already observed in previous works, further highlighting the need to take into account the different surface features when selecting conservation procedures such as the application of inhibitors (i.e. the relative Sn enrichment in unsheltered areas requires inhibitors which effectively interact not only with Cu but also with Sn). 2. The ageing (pre-patination) cycle on coupons was able to reproduce the relative Sn enrichment that actually happens in real patinated surfaces, making the bronze specimens representative of the real support for bronze inhibitors. 3. The non-toxic silane-based inhibitors display a good protective efficiency towards pre-patinated surfaces, differently from other widely used inhibitors such as benzotriazole (BTA) and its derivatives. 4. The 3-mercapto-propyl-trimethoxy-silane (PropS-SH) additivated with CeO2 nanoparticles generally offered a better corrosion protection than PropS-SH.

Detailed study of the seismotectonic setting in the Lucanian Apennines and surrounding areas (Southern Italy)

In this research work I analyzed the instrumental seismicity of Southern Italy in the area including the Lucanian Apennines and Bradano foredeep, making use of the most recent seismological database available so far. I examined the seismicity occurred during the period between 2001 and 2006, considering 514 events with magnitudes M ≥ 2.0. In the first part of the work, P- and S-wave arrival times, recorded by the Italian National Seismic Network (RSNC) operated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), were re-picked along with those of the SAPTEX temporary array (2001–2004). For some events located in the Upper Val d'Agri, I also used data from the Eni-Agip oil company seismic network. I computed the VP/VS ratio obtaining a value of 1.83 and I carried out an analysis for the one-dimensional (1D) velocity model that approximates the seismic structure of the study area. After this preliminary analysis, making use of the records obtained in the SeSCAL experiment, I incremented the database by handpicking new arrival times. My final dataset consists of 15,666 P- and 9228 S-arrival times associated to 1047 earthquakes with magnitude ML ≥ 1.5. I computed 162 fault-plane solutions and composite focal mechanisms for closely located events. I investigated stress field orientation inverting focal mechanism belonging to the Lucanian Apennine and the Pollino Range, both areas characterized by more concentrated background seismicity. Moreover, I applied the double difference technique (DD) to improve the earthquake locations. Considering these results and different datasets available in the literature, I carried out a detailed analysis of single sub-areas and of a swarm (November 2008) recorded by SeSCAL array. The relocated seismicity appears more concentrated within the upper crust and it is mostly clustered along the Lucanian Apennine chain. In particular, two well-defined clusters were located in the Potentino and in the Abriola-Pietrapertosa sector (central Lucanian region). Their hypocentral depths are slightly deeper than those observed beneath the chain. I suggest that these two seismic features are representative of the transition from the inner portion of the chain with NE-SW extension to the external margin characterized by dextral strike-slip kinematics. In the easternmost part of the study area, below the Bradano foredeep and the Apulia foreland, the seismicity is generally deeper and more scattered and is associated to the Murge uplift and to the small structures present in the area. I also observed a small structure NE-SW oriented in the Abriola-Pietrapertosa area (activated with a swarm in November 2008) that could be considered to act as a barrier to the propagation of a potential rupture of an active NW-SE striking faults system. Focal mechanisms computed in this study are in large part normal and strike-slip solutions and their tensional axes (T-axes) have a generalized NE-SW orientation. Thanks to denser coverage of seismic stations and the detailed analysis, this study is a further contribution to the comprehension of the seismogenesis and state of stress of the Southern Apennines region, giving important contributions to seismotectonic zoning and seismic hazard assessment.

Local home bias: Theory and new empirical evidence from Italy

This thesis examines the literature on local home bias, i.e. investor preference towards geographically nearby stocks, and investigates the role of firm’s visibility, profitability, and opacity in explaining such behavior. While firm’s visibility is expected to proxy for the behavioral root originating such a preference, firm’s profitability and opacity are expected to capture the informational one. I find that less visible, and more profitable and opaque firms, conditionally to the demand, benefit from being headquartered in regions characterized by a scarcity of listed firms (local supply of stocks). Specifically, research estimates suggest that firms headquartered in regions with a poor supply of stocks would be worth i) 11 percent more if non-visible, non-profitable and non-opaque; ii) 16 percent more if profitable; and iii) 28 percent more if both profitable and opaque. Overall, as these features are able to explain most, albeit not all, of the local home bias effect, I reasonably argue and then assess that most of the preference for local is determined by a successful attempt to exploit local information advantage (60 percent), while the rest is determined by a mere (irrational) feeling of familiarity with the local firm (40 percent). Several and significant methodological, theoretical, and practical implications come out.

La disciplina della gestione aeroportuale e dei servizi aeroportuali nel diritto dei trasporti europeo e nazionale

Dopo gli indubbi sviluppi politici e legali tendenti all’uniformazione è inevitabile non sostenere che anche il mercato della gestione delle infrastrutture e del trasporto aereo a terra costituisce un fattore determinante del trasporto aereo con una più stretta necessità di uniformazione del quadro regolamentare. La gestione aeroportuale e i servizi connessi è collocata all’interno del diritto aereo. Perché si configuri il “trasporto aereo” (nozione dinamica base che caratterizza il diritto del trasporto aereo) si ha la necessità di un accordo tra due paesi – un permesso di volo designato – una finestra di orario di decollo e atterraggio e la regolamentazione delle relative attività connesse, affinché si svolgano in situazione di safety, quale conditio sine qua non di tutte le attività di aviazione. Tuttavia, la migliore dottrina sente il bisogno di una trattazione separata della materia diritto aereo in senso stretto e quella della disciplina aeroportuale, benché i due ambiti sono tra di loro contigui. Questo è legittimato da esigenze contrapposte fra gli operatori dei due settori. In ultima considerazione possiamo sostenere che gli sviluppi legislativi, sia nel diritto aeronautico e in quello marittimo, portano all’abbraccio della impostazione di un diritto dei trasporti inclusivo di ogni forma dell’attuazione del fenomeno trasporto, scollegandosi al solo fenomeno dell’esercizio nautico quale elemento caratterizzante della disciplina. Quale futuro legislativo si prospetta per la gestione del bene aeroporto? Quale sarà la sua dimensione legale su questioni importanti sulle quali esiste una normazione europea come l’allocazione delle bande orarie, tasse aeroportuali e assistenza a terra oppure su quelle che hanno un carattere prevalentemente nazionale? E infine, quale sarebbe la strada da seguire per regolare il nuovo mercato aeroportuale che è passato dalla idea della competizione per il mercato esplorando anche la competizione nel mercato, con aeroporti che si comportano come operatori in concorrenza tra loro?

L’autotutela collettiva tra ipotesi di revisione della disciplina nazionale e prospettive europee

Nel presente lavoro viene trattato il delicato tema dell’autotutela collettiva, nell’intersezione tra ipotesi di revisione nazionale e prospettive europee. Dapprima viene ricostruita l’evoluzione della valutazione del conflitto collettivo nell’ordinamento giuridico italiano ed effettuata una ricognizione delle diverse manifestazioni del conflitto collettivo ivi riscontrabili. Il tentativo è quello di superare i limiti di una trattazione ristretta allo sciopero e di verificare la perdurante validità della tradizionale nozione di sciopero, intesa esclusivamente come astensione collettiva dalle prestazioni di lavoro. In un secondo capitolo vengono esaminati i disegni di legge di riforma in materia di conflitto collettivo, presentati nel corso della XVI legislatura e le clausole, incidenti sulla medesima materia, rinvenibili nell’Accordo interconfederale del 28 giugno 2011 e negli accordi FIAT del 2010, relativi agli stabilimenti di Pomigliano D’Arco e Mirafiori. Alla luce di tali materiali, si riesaminano le tematiche della titolarità individuale del diritto di sciopero, delle clausole di tregua e delle procedure arbitrali e conciliative. Successivamente, viene esaminata la produzione legislativa e giurisprudenziale comunitaria in tema di conflitto collettivo. Il confronto con l’ordinamento nazionale consente di mettere criticamente in luce il diverso rapporto tra mercato e diritti d’azione collettiva e di rilevare che nell’ordinamento comunitario la giurisprudenza della Corte di giustizia abbia introdotto limiti eccessivi al dispiegarsi dei diritti sociali in esame. Da ultimo, vengono formulate alcune considerazioni conclusive. Criticamente viene rilevato come, in tempi di globalizzazione, non viene prestata sufficiente attenzione alla valorizzazione del conflitto collettivo, come motore dell’emancipazione e del progresso sociale.

Agricultural Genetics and Plant Breeding in Early Twentieth-Century Italy

This thesis is about plant breeding in Early 20th-Century Italy. The stories of the two most prominent Italian plant-breeders of the time, Nazareno Strampelli and Francesco Todaro, are used to explore a fragment of the often-neglected history of Italian agricultural research. While Italy was not at the forefront of agricultural innovation, research programs aimed at varietal innovation did emerge in the country, along with an early diffusion of Mendelism. Using philosophical as well as historical analysis, plant breeding is analysed throughout this thesis as a process: a sequence of steps that lays on practical skills and theoretical assumptions, acting on various elements of production. Systematic plant-breeding programs in Italy started from small individual efforts, attracting more and more resources until they became a crucial part of the fascist regime's infamous agricultural policy. Hybrid varieties developed in the early 20th century survived World War II and are now ancestors of the varieties that are still cultivated today. Despite this relevance, the history of Italian wheat hybrids is today largely forgotten: this thesis is an effort to re-evaluate a part of it. The research did allow previously unknown or neglected facts to emerge, giving a new perspective on the infamous alliance between plant-breeding programs and the fascist regime. This thesis undertakes an analysis of Italian plant-breeding programs as processes. Those processes had a practical as well as a theoretical side, and involved various elements of production. Although a complete history of Italian plant breeding still remains to be written, the Italian case can now be considered along with the other case-studies that other scholars have developed in the history of plant breeding. The hope is that this historical and philosophical analysis will contribute to the on-going effort to understand the history of plants.

L(ocus) d(atos) d(ecreto) d(ecurionum): La concessione di spazi pubblici nelle comunita' cittadine dell'italia romana

La tesi riguarda la concessione di spazi di proprietà pubblica a privati, intesi come singole persone o enti, quali ad esempio i collegi, da parte delle autorità cittadine. Le fonti a disposizione per indagare tale pratica burocratica sono quasi totalmente di natura epigrafica, per lo più attestanti l’espressione locus datus decreto decurionum, variamente abbreviata, o formule similari. Questo aspetto della vita civica è stata cursoriamente oggetto di studio in diversi contributi, ma si tratta di articoli che circoscrivono il tema, analizzandolo in relazione a ristrette aree geografiche, oppure considerandone determinati aspetti (ad esempio l’ambito sacro o quello funerario). Si è perciò ritenuto utile proseguire questa linea di ricerca affrontando uno studio di più ampio raggio, che comprenda la documentazione epigrafica dell’intero territorio italico (costituito dalle undici regioni augustee ad esclusione di Roma), per tutte le tipologie testuali (iscrizioni sacre, funerarie, onorarie, su opera pubblica, exempla decreti), allo scopo di formulare osservazioni più precise e puntuali sulla procedura burocratica in esame, pur con tutti i limiti noti a chi affronti questo genere di indagine. Tra le conclusioni raggiunte, è emerso come durante il I-II sec. d.C. vi fosse la tendenza a concedere, sporadicamente, dei loca sepulturae extraurbani a membri delle famiglie delle élites cittadine, anche donne e fanciulli, mentre il foro e le altre aree pubbliche interne alla città erano soprattutto utilizzate direttamente dai decurioni per l’elevazione di dediche e statue. Nel corso del II sec. d.C., con massima diffusione nell’età antonina e poi in quella severiana, prese invece piede l’uso privato a scopo onorario degli spazi pubblici siti all’interno delle città, ovvero in aree prima pressoché precluse all’intervento di singoli cittadini: familiari e liberti, collegi e altri organismi commissionavano statue dedicate prevalentemente agli amministratori locali, magistrati cittadini spesso divenuti anche cavalieri.

Città e architettura a Faenza nel Rinascimento. Progetti e strategie di rinnovamento urbano nell'età di Carlo II Manfredi (1468-77)

La tesi ha come oggetto il rinnovamento urbano che fu realizzato a Faenza per opera del suo signore Carlo II Manfredi tra il 1468 e il 1477, d’accordo con il fratello, il vescovo Federico. La prima opera realizzata da Carlo fu il portico a due livelli che dotò di una nuova facciata il suo palazzo di residenza, di origini medievali. Questa architettura sarebbe stata il preludio di un riordino generale della piazza principale della città, probabilmente allo scopo di ricreare un foro all’antica, come prescritto dai trattati di Vitruvio e di Alberti. L’aspetto originale del loggiato rinascimentale, desumibile da documentazione archivistica e iconografica, permette di attribuirlo con una certa probabilità a Giuliano da Maiano. Oltre alla piazza, Carlo riformò profondamente il tessuto urbano, demolendo molti portici lignei di origine medievale, rettificando le principali strade, completando la cerchia muraria. Federico Manfredi nel 1474 diede inizio alla fabbrica della Cattedrale, ricostruita dalle fondamenta su progetto dello stesso Giuliano da Maiano. L’architettura della chiesa ha uno stile largamente debitore all’architettura sacra di Brunelleschi, ma con significative differenze (come la navata definita da un’alternanza tra pilastri e colonne, o la copertura composta da volte a vela). L’abside della cattedrale, estranea al progetto maianesco, fu realizzata nel 1491-92 e mostra alcuni dettagli riconducibili alla coeva architettura di Bramante. A Faenza si realizza in un periodo di tempo brevissimo una profonda trasformazione del volto della città: loggiato, riforma della piazza, riordino delle strade, una nuova cattedrale, tutto contribuisce a dare lustro ai Manfredi e a fare di Faenza una città moderna e in cui si mettono in pratica, forse per la prima volta nell’Italia settentrionale, i dettami di Vitruvio e di Alberti.

Strumenti di prevenzione e riduzione degli sprechi alimentari. Un piano nazionale per l'Italia

Negli ultimi anni lo spreco alimentare ha assunto un’importanza crescente nel dibattito internazionale, politico ed accademico, nel contesto delle tematiche sulla sostenibilità dei modelli di produzione e consumo, sull’uso efficiente delle risorse e la gestione dei rifiuti. Nei prossimi anni gli Stati Membri dell’Unione Europea saranno chiamati ad adottare specifiche strategie di prevenzione degli sprechi alimentari all’interno di una cornice di riferimento comune. Tale cornice è quella che si va delineando nel corso del progetto Europeo di ricerca “FUSIONS” (7FP) che, nel 2014, ha elaborato un framework di riferimento per la definizione di “food waste” allo scopo di armonizzare le diverse metodologie di quantificazione adottate dai paesi membri. In questo scenario, ai fini della predisposizione di un Piano Nazionale di Prevenzione degli Sprechi Alimentari per l’Italia, il presente lavoro applica per la prima volta il “definitional framework” FUSIONS per l’analisi dei dati e l’identificazione dei principali flussi nei diversi anelli della filiera e svolge un estesa consultazione degli stakeholder (e della letteratura) per identificare le possibili misure di prevenzione e le priorità di azione. I risultati ottenuti evedenziano (tra le altre cose) la necessità di predisporre e promuovere a livello nazionale l’adozione di misure uniformi di quantificazione e reporting; l’importanza del coinvolgimento degli stakeholder nel contesto di una campagna nazionale di prevenzione degli sprechi alimentari; l’esigenza di garantire una adeguata copertura economica per le attività di pianificazione e implementazione delle misure di prevenzione da parte degli enti locali e di un coordinamento a livello nazionale della programmazione regionale; la necessità di una armonizzazione/semplificazione del quadro di riferimento normativo (fiscale, igienico-sanitario, procedurale) che disciplina la donazione delle eccedenze alimentari; l’urgenza di approfondire il fenomeno degli sprechi alimentari attraverso la realizzazione di studi di settore negli stadi a valle della filiera.

La normativa europea e nazionale in materia di biodiversita: Analisi contrastiva dei recepimenti nazionali in spagna e in italia e costruzione di risorse per la traduzione

El objetivo del presente trabajo es desarrollar una actividad de soporte a la traducción a través de un análisis lingüístico en clave contrastiva de los documentos comunitarios y nacionales de Italia y España en materia de biodiversidad por una parte, y la creación de un recurso de traducción que consta de una memoria de traducción y un banco de datos terminólogico para traductores y usuarios no expertos por otra parte. La idea para el desarrollo de esta tesis tiene origen en una experiencia de formación llevada a cabo en el mes de octubre de 2015 en la sede de la DGT de Luxemburgo en la que se contribuyó a la actividad terminológica del grupo de terminólogos IATE sobre todo por lo que se refiere a la Política Agrícola Común. El trabajo consta de cinco capítulos. El Capítulo I está dedicado a la normativa comunitaria y nacional en materia de biodiversidad, a la situación actual en los dos países considerados y a la presentación de los documentos analizados. El Capítulo II se centra en el régimen lingüístico de la Unión europea, en la experiencia de formación en la DGT de Luxemburgo y en la presentación de las herramientas utilizadas para la construcción del banco de datos terminológico y la memoria de traducción. En el Capítulo III se analizan las lenguas de especialidad, en particular la jurídica y la científica, y se presentan los fenómenos lingüísticos que las caracterizan con la finalidad de averiguar, mediante el análisis llevado a cabo en el siguiente Capítulo IV, en qué medida las Estrategias consideradas resultan innovadoras y qué intenciones pragmáticas tienen. El Capítulo V ilustra el trabajo de creación de los corpus de consulta con los que se ha realizado la memoria de traducción, y las fases que han llevado a la catalogación terminológica y a la elaboración del banco de datos terminológico sobre la biodiversidad. El trabajo incluye las fichas terminológicas creadas tras la sistematización conceptual.

A feasibility study for the provision of electronic healthcare tools and services in areas of Greece, Cyprus and Italy

Background Through this paper, we present the initial steps for the creation of an integrated platform for the provision of a series of eHealth tools and services to both citizens and travelers in isolated areas of thesoutheast Mediterranean, and on board ships travelling across it. The platform was created through an INTERREG IIIB ARCHIMED project called INTERMED. Methods The support of primary healthcare, home care and the continuous education of physicians are the three major issues that the proposed platform is trying to facilitate. The proposed system is based on state-of-the-art telemedicine systems and is able to provide the following healthcare services: i) Telecollaboration and teleconsultation services between remotely located healthcare providers, ii) telemedicine services in emergencies, iii) home telecare services for "at risk" citizens such as the elderly and patients with chronic diseases, and iv) eLearning services for the continuous training through seminars of both healthcare personnel (physicians, nurses etc) and persons supporting "at risk" citizens. These systems support data transmission over simple phone lines, internet connections, integrated services digital network/digital subscriber lines, satellite links, mobile networks (GPRS/3G), and wireless local area networks. The data corresponds, among others, to voice, vital biosignals, still medical images, video, and data used by eLearning applications. The proposed platform comprises several systems, each supporting different services. These were integrated using a common data storage and exchange scheme in order to achieve system interoperability in terms of software, language and national characteristics. Results The platform has been installed and evaluated in different rural and urban sites in Greece, Cyprus and Italy. The evaluation was mainly related to technical issues and user satisfaction. The selected sites are, among others, rural health centers, ambulances, homes of "at-risk" citizens, and a ferry. Conclusions The results proved the functionality and utilization of the platform in various rural places in Greece, Cyprus and Italy. However, further actions are needed to enable the local healthcare systems and the different population groups to be familiarized with, and use in their everyday lives, mature technological solutions for the provision of healthcare services.
