Hydraulic characterization of the full scale divertor cassette prototype
2011
In the frame of the activities related to ITER divertor R&D, ENEA C.R. Brasimone was in charge by Fusion For Energy (F4E) to perform the assembly, the hydraulic tests and the theoretical simulation of the hydraulic behavior of the full scale divertor cassette prototype. The objective of these activities was aimed at the investigation of the thermal-hydraulic behavior of the full-scale divertor cassette both under steady state condition and during draining and drying operational transient. In particular, the steady state tests were focused on finally check whether the hydraulic design of the divertor components is able to ensure a uniform and proper cooling for the plasma facing components, …
Seven Mathematical Models of Hemorrhagic Shock
2021
Although mathematical modelling of pressure-flow dynamics in the cardiocirculatory system has a lengthy history, readily finding the appropriate model for the experimental situation at hand is often a challenge in and of itself. An ideal model would be relatively easy to use and reliable, besides being ethically acceptable. Furthermore, it would address the pathogenic features of the cardiovascular disease that one seeks to investigate. No universally valid model has been identified, even though a host of models have been developed. The object of this review is to describe several of the most relevant mathematical models of the cardiovascular system: the physiological features of circulator…

Fibronectin-bound α5β1 integrins sense load and signal to reinforce adhesion in less than a second
2017
Integrin-mediated mechanosensing of the extracellular environment allows cells to control adhesion and signalling. Whether cells sense and respond to force immediately upon ligand-binding is unknown. Here, we report that during adhesion initiation, fibroblasts respond to mechanical load by strengthening integrin-mediated adhesion to fibronectin (FN) in a biphasic manner. In the first phase, which depends on talin and kindlin as well as on the actin nucleators Arp2/3 and mDia, FN-engaged α5β1 integrins activate focal adhesion kinase (FAK) and c-Src in less than 0.5 s to steeply strengthen α5β1- and αV-class integrin-mediated adhesion. When the mechanical load exceeds a certain threshold, fib…
Creation of a food taste database using an in-home "taste" profile method
2014
International audience; The purpose of this study was to create a food 'taste' database using an innovative in-home profile method. The five basic tastes and fat sensation were studied. The proposed method consisted in an intensive training in laboratory (55 h, 5 months) immediately followed by an in-home measurements phase (8 months) during which 12 trained panelists had to evaluate the five tastes and fat sensation of the foods they typically consumed. The rating scales were inspired by scales used in the Spectrum (TM) method. During the in-home measurement phase, ratings were reported thanks to a web-based tool and each month the panelists returned to the laboratory for a 2-h retraining …
Equi-intensity across the SpectrumTM taste scales
2015
Abstract This work aimed to study the equi-intensity across the Spectrum™ taste scales. The approach consisted of a comparison of four reference points illustrating the same level of intensity across the scales using two very different methods: 2-alternative forced-choice (2-AFC) and Labeled Magnitude Scale (LMS). The comparisons across these scales were based on caffeine, citric acid, sodium chloride, sucrose, and monosodium glutamate in water solutions, at different concentrations, prepared according to the guidelines given for the Spectrum™ method. A scale concerning the umami taste, designed in the spirit of the Spectrum™ scales, was also studied in this work. Both procedures produced s…
Teachers' perceptions of student engagement and teacher self-efficacy beliefs
2014
This study examines the teachers’ perceptions of student engagement, teachers’ self-efficacy beliefs, and their interrelation. Affective engagement can be understood as belonging or relatedness as well as identification with school. Cognitive engagement can be conceived as engagement in classroom, self-regulation, learning goals and a student’s overall investment in learning. Measuring students’ engagement is crucial in that it helps educators predict and, by amending current teaching practices and policies, avoid poor performance or even drop-out. The teacher’s belief in herself and her potential is critical for the students’ overall performance in class. This study attempts to investigate…
The school staff's perception of their ability to teach special educational needs pupils in inclusive settings in Finland
2015
Recent studies have suggested that the professional training received by general educators does not adequately prepare them to properly implement inclusion-based practices. The idea of inclusion in practice has not significantly changed the situation of teaching pupils with special educational needs (SENs) in mainstream classes. This study's primary intent is to examine the factors that identify the school staff's ability to meet the needs of SEN pupils in their daily teaching situations. A total of 187 elementary school teachers, principals and teaching assistants in a Finnish city completed a structured questionnaire that used a self-evaluation method. Two components were generalised acco…
Development and Initial Validation of the Humor Climate in Sport Scale
2021
In sport teams, humor is an essential element that influences communication processes, and plays an important role in group dynamics. Despite this, no current instrument is presented in the literature to measure humor climate in sport teams. Therefore, the current study presents the development and initial validation of the Humor Climate in Sport Scale (HCSS). The aim was to assess content, structural and concurrent validity of the developed instrument, and to examine differential item functioning (DIF) as a function of sex. Three different phases were completed in this study. The first phase involved focus groups (n= 5) that explored humor as communication in a team sport context. In phase…
Pitfalls in the Development of Agent-Based Models in Social Sciences: Avoiding Them and Learning from Them
2019
The references on the principles and methodology for developing agent-based models of social phenomena usually describe general principles and illustrate the process using worked examples, but seldom focus on the pitfalls and errors that make practical model building a tortuous and difficult task. This chapter contains a discussion of the positive and negative aspects of my personal experience in a PhD work on simulation of large scale social conflict. The purpose will be to describe the process from the initial plan to the final dissertation, analyze the pitfalls and their overcoming in terms of principles of model development, and summarize the ideas that I found useful for practical deve…
