Summary The current Plan summarises the beneficiaries’ strategy and concrete actions related to the protection, dissemination and exploitation of the project results. Horizon 2020 is a Research and Innovation programme aiming at fostering competitiveness and growth and increasing benefits to the European Union economy and citizens. Public investment in projects are to be converted into socio-economic benefits for the society, as clearly indicated in the Horizon 2020 Rules for Participation, with a clear accent to the beneficiaries’ obligations to exploit and disseminate the outcomes of the funded activities. The Horizon 2020 work programme 2014-2015 explicitly specifies that project proposals shall include a draft Plan for the Exploitation and Dissemination of Results. This Plan is a strategic document indicating how the partnership establishes the basis for the intellectual property strategy, dissemination and exploitation activities, and summarises the beneficiaries’ strategy and concrete actions related to the protection, dissemination and exploitation of the project results.

IS-ENES is the distributed e-infrastructure of the European Network for Earth System Modelling (ENES).A complex and heterogeneous infrastructure, IS-ENES encompasses models and tools development, documentation, deployment and sharing (including HPC aspects), data storage, processing and distribution as well as the interface with climate impact science and climate services, therefore serving climate science and the users of climate data. This direct impact has a path to many socio-economic sectors (energy, agriculture, transport, water management, health, safety...), as well as national and international policy makers. IS-ENES' third phase (H2020 funded I3 European project H2020 2019-20122) IS-ENES3 starts as the European climate modelling community faces the challenges of contributing to the next IPCC assessment report through the 6th phase of the Coupled Model Intercomparison Project (CMIP). IS-ENES3 addresses these challenges by developing services to deal with unprecedented data volumes and model complexity. The infrastructure delivers the European part of the Earth System Grid Federation and a central point of entry to services providing access to new data, software, models and tools.IS-ENES3 will further stimulate collaboration, disseminate software and data, and integrate and expand Europe wide its user base. Moreover it will find innovative ways of working with the Copernicus programme, already relying on IS-ENES ESGF services, and with other parts of the European data infrastructure, and with the high performance computing and data analytics industries.We propose to employ a blend of indicators to show the advancement of key aspects/activities toward the achievement of the project's manifold short and long-term impacts. Besides relying on indicators used so far to measure software uptake and use and data processing and download, including the reliability of help and documentation services, we plan in IS-ENES3 to add ways to measure contributions to joint development activities (e.g. for new model modules), map applications for Trans National Access and the landscape of national and international science projects relying on the infrastructure. Targeting infrastructure openness and outreach toward adjacent communities, we deem important to map participation in interoperability initiatives, as well as involvement per community and career stage in IS-ENES outreach and training initiatives. We also aim at discussing ways on how to measure tangible outcomes resulting from engagement with Copernicus, EOSC, other European infrastructures, as well as with the industry. We offer a retrospective analysis of the methodology used in the previous phases of IS-ENES to measure impacts and an outlook of what IS-ENES3 proposes to increase and optimize them. In the crucial moment of preparing sustainability of a mature, heterogeneous, acknowledged yet expanding infrastructure, estimates of the extent of impacts (including financial ones when applicable) and return of target communities might ultimately feed back into infrastructure architecture decisions.

- Abstract
Il lavoro di tesi ha analizzato le perdite AC nei superconduttori ad alta temperatura critica, sia per quanto riguarda la modellazione software, che per le misure sperimentali. Dapprima è stato costruito un modello tramite COMSOL Multiphysics di un nastro superconduttore sottoposto a campo magnetico esterno variabile e corrente di trasporto imposta. La sua validità è stata confermata dalla congruenza con le formule analitiche presenti in letteratura riguardanti la potenza dissipata. Sulla base delle simulazioni numeriche effettuate è stato possibile iniziare il dimensionamento di un sistema di misura. L'apparato di misura realizzato è stato costruito ad hoc per un provino in GdBCO, dunque in modo adeguato alla determinazione delle perdite sul provino. L'elettronica coinvolta è stata analizzata, nei suoi limiti e nel suo funzionamento, composta da un generatore di segnale, una scheda di acquisizione, un amplificatore stereo e un trasformatore di misura. Tali dispositivi sono stati inseriti nel circuito per ottenere un'acquisizione con risoluzione adeguata alla misura della caduta di tensione sul superconduttore, a fronte di alti valori di corrente su di esso: prossimi alla corrente critica. I dati ottenuti presentano valori più alti di quelli attesi, possibile conseguenza delle caratteristiche del sistema di acquisizione. Lo studio effettuato ha risposto in modo soddisfacente per quanto riguarda l'andamento delle perdite al variare della frequenza di alimentazione: la loro dipendenza dalla frequenza è confermata dalle formule analitiche disponibili.

- Abstract
A coupled atmosphere-ocean general circulation model, ECHAM5-MPIOM, was used to study the multicompartmental cycling and long-range transport of persistent and semivolatile organics. Multiphase systems in air and ocean are covered by submodels for atmospheric aerosols, HAM, and marine biogeochemistry, HAMOCC5, respectively. The model, furthermore, encompasses 2D surface compartments, i.e. top soil, vegetation surfaces and sea-ice. The total environmental fate of gamma-hexachlorocyclohexane (gamma-HCH, lindane) and dichlorophenyltrichloroethane (DDT) in agriculture were studied. DDT is mostly present in the soils, the water-soluble gamma-HCH in soils and ocean. DDT has the longest residence time in almost all compartments. Quasi-steady state with regard to substance accumulation is reached within a few years in air and vegetation surfaces. In seawater the partitioning to suspended and sinking particles contributes to the vertical transport of substances. On the global scale deep water formation is, however, found to be more efficient. Up to 30% of DDT but only less than 0.2% of gamma-HCH in seawater are stored in particulate matter. On the time scale studied (1 decade) and on global scale substance transport in the environment is determined by the fast atmospheric circulation. The meridional transport mechanism, for both compounds, is significantly enhanced by multi-hopping. Net meridional transport in the ocean is effective only regionally, mostly by currents along the western boundaries of Africa and the Americas. The total environmental burdens of the substances experience a net northward migration from their source regions, which is more pronounced for DDT than for gamma-HCH. Due to the application distribution, however, after 10 years of simulation 21% of the global environmental burden of gamma-HCH and 12% of DDT have accumulated in the Arctic.
