MELCOR per lo Studio Integrale di Sequenze Incidentali su Reattori PWR da 900 MWe e valutazioni preliminari d'impatto a breve e medio raggio
2014
Il presente documento è stato preparato nel corso della seconda annualità dell'AdP ENEA-MSE nell'ambito dell'obiettivo B-Task B_1 (Sviluppo di una Metodologia per Valutazioni di Sicurezza in Condizioni Incidentali o di Pre-Emergenza) della Linea Progettuale 1 (Sviluppo competenze scientifiche nel campo della sicurezza nucleare). Esso riporta i principali risultati della simulazione MELCOR di un transitorio del tipo “short term Station Blackout (SBO)” con possibile rottura dei tubi a U del GV (Steam Generator Tube Rupture - SGTR) indotta da stress termici e un lavoro preliminare di raccolta di informazioni sulle potenzialità presentate da alcune piattaforma di simulazione ad oggi utilizzate …

In actinomycetes, antibiotic production is often associated with a morpho-physiological differentiation program that is regulated by complex molecular and metabolic networks. Many aspects of these regulatory circuits have been already elucidated and many others still deserve further investigations. In this regard, the possible role of many small open reading frames (smORFs) in actinomycete morpho-physiological differentiation is still elusive. In Streptomyces coelicolor, inactivation of the smORF trpM (SCO2038) – whose product modulates L-tryptophan biosynthesis – impairs production of antibiotics and morphological differentiation. Indeed, it was demonstrated that TrpM is able to interact w…
Possibilities for Intervention in Domestic Violence: Frame Analysis of Health Care Professionals’ Attitudes
2014
ABSTRACT. Violence is a serious problem, and social and health care providers are in a key position for implementing successful interventions. This qualitative study of 6 focus groups with professionals (n = 30) examines the health care professionals’ ways of framing a domestic violence intervention. Of special interest here is how professionals see their own roles in the process of recognizing and helping victims of domestic violence. By using Erving Goffman's frame analysis, this study identifies several frames that either: a) emphasize the obstacles to intervention and justify nonintervention, or on the contrary, b) question these obstacles and find justifications for intervention. The p…

Diseño y síntesis de nuevos materiales conmutables basados en el fenómeno de transición de espín
2023
Esta Tesis Doctoral actúa como compendio de síntesis y caracterización de nuevos materiales, generalmente porosos, que presentan el fenómeno de transición de espín (en inglés Spin Crossover, SCO). El principal objetivo de la Tesis Doctoral ha consistido en el diseño de estos nuevos polímeros de coordinación que combinan de forma sincrónica el fenómeno SCO asociado a los centros metálicos de FeII con otras propiedades de interés, siendo la motivación última su futura aplicación en dispositivos espintrónicos. Más concretamente, los esfuerzos sintéticos se han dedicado a la obtención de polímeros de coordinación de tipo Hofmann 2D que presentan: propiedades anfitrión-huésped selectivas, fluore…
A Statecharts-Based Approach for WSN Application Development

Wireless Sensor Network (WSN) software development challenges developers in two main ways: through system programming, which requires expertise in hardware and network management
Distress, Eustress, or No Stress? Explaining Smartphone Users' Different Technostress Responses
2018
Technostress is common and has harmful consequences. Therefore, researchers have shown increasing interest in explaining technostress in the field of information systems (IS). While extant research merits in identifying the causes and consequences of technostress, it has not explained empirically why information technology (IT) users have different responses to similar potentially stressful IT events. Indeed, events such as smartphone failures can derive negative distress responses for some users and positive eustress responses for others. To address this gap in research, we conducted a qualitative study by interviewing users who had experienced smartphone failures. As a contribution, our f…
Framing War and the Nonhuman in Science-Fiction Television: The Affective Politics of V
2020
This article investigates how war between humans and aliens is framed in the original and reimagined versions of the SF television series V and the affective responses and ethical considerations that these frames evoke. Inspired by the work of Judith Butler and Sarah Ahmed and by posthumanist thinking, I analyse how SF television takes part in the cultural formation of “livable lives” for both human and nonhuman beings. It is argued that the kinds of violence that art or the media, including fiction, represent matter for the formation of ethical and political responses to violence. peerReviewed
Riesz-Fischer Maps, Semi-frames and Frames in Rigged Hilbert Spaces
2021
In this note we present a review, some considerations and new results about maps with values in a distribution space and domain in a σ-finite measure space X. Namely, this is a survey about Bessel maps, frames and bases (in particular Riesz and Gel’fand bases) in a distribution space. In this setting, the Riesz-Fischer maps and semi-frames are defined and new results about them are obtained. Some examples in tempered distributions space are examined.
Application of Periodic Frames to Image Restoration
2014
In this chapter, we present examples of image restoration using periodic frames. Images to be restored were degraded by blurring, aggravated by random noise and random loss of significant number of pixels. The images are transformed by periodic frames designed in Sects. 17.2 and 17.4, which are extended to the 2D setting in a standard tensor product way. In the presented experiments, performances of different tight and semi-tight frames are compared between each other in identical conditions.
