On the thermomechanical behavior of the European target assembly design of IFMIF-EVEDA lithium test loop under start-up transient scenarios

2013

Uncoupled thermomechanical transient analyses have been carried out to investigate the behavior of IFMIF-EVEDA lithium test loop bayonet backplate target assembly under two selected start-up transient operational scenarios. The first transient scenario considered foresees that the target assembly, starting from the initial uniform temperature of 50 C, is heated up uniquely by convective heat transfer with lithium, flowing from inlet to outlet nozzle at its reference nominal temperature and pressure, until its nominal steady state thermal field distribution is reached. The second transient scenario foresees, more realistically, that the target assembly, starting from the uniform temperature …

Study of the thermo-mechanical performances of the IFMIF-EVEDA Lithium Test Loop target assembly

2012

Abstract Within the framework of the IFMIF R&D program and in close cooperation with ENEA-Brasimone, at the Department of Energy of the University of Palermo a research campaign has been launched to investigate the thermo-mechanical behavior of the target assembly under both steady state and start-up transient conditions. A theoretical approach based on the finite element method (FEM) has been followed and a well-known commercial code has been adopted. A realistic 3D FEM model of the target assembly has been set-up and optimized by running a mesh independency analysis. A proper set of loads and boundary conditions, mainly concerned with radiation heat transfer between the target assembly ex…

Thermomechanical analysis supporting the preliminary engineering design of DONES target assembly

2018

Abstract The design of the Demo Oriented NEutron Source (DONES) is the main objective of the Work Package Early Neutron Source (WPENS) of EUROfusion Power Plant Physics and Technology (PPPT) programme. DONES is an IFMIF-based neutron source with the goal of testing and qualifying candidate materials to be used in DEMO and future fusion power plants. In the framework of these activities, a research campaign has been carried out at the University of Palermo, in close cooperation with ENEA labs, in order to assess the thermomechanical performances of the DONES target system, endowed with an integrated Target Assembly (TA) when it undergoes the thermomechanical loads typical of its nominal oper…

Raising awareness on Sustainable Development Goals (SDGs) through Lego Serious Play (LSP)

2020

[EN] In September 2015, world leaders agreed on a new sustainable development agenda based on a set of global goals aimed at eradicating poverty, ensuring planet protection and guaranteeing prosperity for future generations (Stafford-Smith et al., 2017). Since then, the education sector has played a fundamental role, not only raising awareness among young people about the importance of Sustainable Development Goals (SDGs) but also promoting innovative ideas around sustainability (Owens, 2017). SDGs implementation needs of business actors rethinking their understanding of economic growth, taking into consideration not only economic aspects but also social and ecological concerns (Crespo et a…

Conversion of Organic Dyes into Pigments: Extraction of Flavonoids from Blackberries (Rubus ulmifolius) and Stabilization

2021

The blackberry’s color is composed mainly of natural dyes called anthocyanins. Their color is red–purple, and they can be used as a natural colorant. Anthocyanins are flavonoids, which are products of plants, and their colors range from orange and red to various shades of blue, purple and green, according to pH. In this study, the chemical composition of an extract obtained from blackberries was defined by LC-ESI/LTQOrbitrap/MS in positive and negative ionization mode. Furthermore, we investigated the adsorption process of blackberry extract using several inorganic fillers, such as metakaolin, silica, Lipari pumice, white pozzolan and alumina. The pigments exhibit different colors as a func…

El Discmón de Terry Pratchett com a eina de motivació i aprenentatge a l'aula de 1r d'ESO. Un estudi de cas

2021

El present Treball de Fi de Màster és un estudi de cas sobre la posada en funcionament d’una seqüència didàctica amb un grup de 1r d’ESO, pertanyent a un IES de titularitat pública de València, el febrer i març de 2021. Aquesta seqüència, anomenada Relats del Discmón, es construeix com una investigació-acció i es desplega en el context de l’Àmbit Sociolingüístic. Aquesta experiència educativa es basa la interdisciplinarietat i les metodologies actives, i pren forma en una sèrie de tallers de gamificació, lectura i escriptura, creats a partir de l’univers de literatura fantàstica Discmón, desenvolupat per l’autor Terry Pratchett. Amb aquest desplegament, es pretén posar a prova el Discmón (i…

Motivating Physical Activity for Individuals with Intellectual Disability through Indoor Bike Cycling and Exergaming.

2022

People with intellectual disabilities have more sedentary lifestyles than the general population. Regular physical activity is of both medical and social importance, reducing the risk of cardiovascular disease and promoting functioning in everyday life. Exergames have been envisioned for promoting physical activity; however, most of them are not user-friendly for individuals with intellectual disabilities. In this paper, we report the design, development, and user acceptance of a mobile health solution connected to sensors to motivate physical activity. The system is mounted on an indoor stationary bicycle and an ergometer bike tailored for people with intellectual disabilities. The develop…
