Rapporto sulla modellistica applicata ai reattori evolutivi
Full text linkIl presente documento riferisce sulle attività svolte nel corso della seconda annualità dell'AdP ENEA-MSE nell'ambito dell'obiettivo B (Piattaforme per la modellistica) della Linea Progettuale 5. Il documento intende dare un quadro dell'attuale modellistica applicata nello studio della sicurezza dei reattori evolutivi e dell'approccio seguito per la sua corretta applicazione. Inoltre, alla luce del rinato interesse dell'Italia verso il nucleare, esso fornisce informazioni sugli strumenti di calcolo disponibili in ENEA per l'effettuazione di studi a supporto di processi decisionali ed autorizzativi per l'installazione di reattori nucleari di III generazione
Definizione di una prova sperimentale da effettuarsi sull'impianto SPES2 della SIET di Piacenza
Full text linkIl presente documento riferisce su attività svolte nel corso della terza annualità dell'AdP ENEA-MSE nell'ambito dell'obiettivo E (Sviluppo e validazione codici di calcolo) della Linea Progettuale 2. In particolare, l'attività di cui tratta il documento si colloca tra quelle propedeutiche al riutilizzo della facility integrale SPES-2 situata presso i laboratori SIET di Piacenza. Allo scopo di riproporre la facility nell'ambito di programmi internazionali per lo studio della sicurezza di reattori LWR evolutivi si intende effettuare una prova sperimentale su una tematica di interesse attuale. Il recupero del modello numerico della facility, la sua revisione ed il suo utilizzo per la simulazione di un transitorio incidentale di perdita di refrigerante di piccole dimensioni (SBLOCA) con lo scopo di investigare il fenomeno di "boron dilution" in condizioni di inventario di massa ridotto sono le varie fasi che hanno portato alla definizione della prova
Perfectionism and eating-related symptoms in young children: a systematic review
No full textPerfectionism is a multidimensional personality trait that encom- passes two higher-order dimensions: Perfectionistic Strivings (i.e., the strive to achieve exceedingly high standards) and Perfectionistic Concerns (i.e., negative self-evaluation and fear of failure). Both dimensions are related to eating disorders (EDs) in clinical and community adults. The association between perfectionism and EDs has also been observed in children but, to date, no review has summarized the relevant empirical findings with children under the age of 14. English-language studies published up to 2019 were searched in online databases (PsycINFO, Medline, PsycArticle) by using the pertinent keywords. Eligible publica- tions reported at least one relationship between perfectionism and eating-related symptoms in children. Data were examined using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. For the 14 studies that were included, 11 studies provided evidence supporting the relationship between perfectionism and ED outcomes, with the majority adopting a unidimensional approach for perfectionism assessment. Among the studies that used multidimensional assessment of perfection- ism, the majority supported the involvement of perfectionistic strivings. Implications of results for children are discussed

Transient analysis of "2 inch Direct Vessel Injection line break" in SPES-2 facility by using TRACE code
No full textIn the past few decades a lot of theoretical and experimental researches have been done to understand the physical phenomena characterizing nuclear accidents. In particular, after the Three Miles Island accident, several reactors have been designed to handle successfully LOCA events. This paper presents a comparison between experimental and numerical results obtained for the "2 inch Direct Vessel Injection line break" in SPES-2. This facility is an integral test facility built in Piacenza at the SIET laboratories and simulating the primary circuit, the relevant parts of the secondary circuits and the passive safety systems typical of the AP600 nuclear power plant. The numerical analysis here presented was performed by using TRACE and CATHARE thermal-hydraulic codes with the purpose of evaluating their prediction capability. The main results show that the TRACE model well predicts the overall behaviour of the plant during the transient, in particular it is able to simulate the principal thermal-hydraulic phenomena related to all passive safety systems. The performance of the presented CATHARE noding has suggested some possible improvements of the model. © Published under licence by IOP Publishing Ltd
In-Network Programmability for Next-generation Personal Cloud Service Support (INPUT)
No full textAbstractIn order to overcome the cloud service performance limits, the INPUT Project aims to go beyond the typical IaaS-based service models by moving computing and storage capabilities from the datacenters to the edge network, and consequently moving cloud services closer to the end users. This approach, which is compatible with the concept of fog computing, will exploit Network Functions Virtualization (NFV) and Software Defined Networking (SDN) to support personal cloud services in a more scalable and sustainable way and with innovative added-value capabilities
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
