Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM

2014

Published version of an article in the journal: Materials and Structures. Also available from the publisher at: http://dx.doi.org/10.1617/s11527-014-0457-6 Open Access New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those of materials already well known, such as silica fume. Several test methods are standardized for making such comparisons, regulated by both European (EN) and American (ASTM) standards. Standardization indicates that procedures are secured to make comparisons valid and informative. In this article the sensit…

Attività di orientamento all’Università: l’impatto delle buone pratiche

2023

The research was carried out as part of a vast project to combat failure in university studies, the provision of guidance and mentoring for students entering the university for the first time, with a view to improving the services offered. First, it was meant to verify the content validity of a self-assessment questionnaire of one's own study habits (ASU 2021) built and validated more than twenty years ago. The questionnaire invites the student to answer not about what he feels he should do, but about what he actually does. Depending on the study difficulties highlighted by the test, laboratory meetings were arranged to plan orientation activities for students of the last two years of secon…

In situ measurements of background aerosol and subvisible cirrus in the tropical tropopause region

2002

[1] In situ aerosol measurements were performed in the Indian Ocean Intertropical Convergence Zone (ITCZ) region during the Airborne Polar Experiment-Third European Stratospheric Experiment on Ozone (APE-THESEO) field campaign based in Mahe, Seychelles between 24 February and 6 March 1999. These are measurements of particle size distributions with a laser optical particle counter of the Forward Scattering Spectrometer Probe (FSSP)-300 type operated on the Russian M-55 high-altitude research aircraft Geophysica in the tropical upper troposphere and lower stratosphere up to altitudes of 21 km. On 24 and 27 February 1999, ultrathin layers of cirrus clouds were penetrated by Geophysica directly…

Effects of Task-Specific and Strength Training on Simulated Military Task Performance in Soldiers.

2020

A soldier’s occupational physical task requirements are diverse and varied. However, the type of physical training that most effectively improves soldiers’ occupational task requirements has not been studied previously. The purpose of this study was to determine the important strength characteristics for soldiers during a repeated simulated military task course, and the type of training that may be effective to improve these abilities during a specialized military training period. Forty-two (n = 42) soldiers participated in the study. They were divided into three training groups; a soldier task-specific training group (TSG, n = 17), a strength training group (STG, n = 15), and a control gro…

When nerves hit : The effect of trait anxiety, situational stress, and task mastery on the perception and interpersonal accuracy of musical expressiv…

2023

Publisher Copyright: Copyright © 2023 Chang-Arana, Mavrolampados, Pokki and Thompson. Music performance anxiety (MPA) is a prevalent phenomenon with potentially serious consequences to a musician’s wellbeing and professional career. Yet, MPA does not always affect performance quality. It is hypothesized that trait anxiety, situational stress, and task mastery can exacerbate the effects of MPA and affect performance quality. Furthermore, it is unclear whether these effects are noticeable to both listeners and performing musicians. We measure performance quality as the expressiveness scores assigned by musicians and listeners to a set of pre-recorded performances. We selected three pianists w…

Governing at the frontier of the European Commission : the case of seconded national officials

2005

Studies of executive institutions have largely dealt separately with national and international executive institutions (IEIs). This study unpacks and repacks four conflicting decision-making dynamics that unfolds at the frontier of IEIs – that is, at the institutional rim where national and international executive institutions meet, interact and collide. The empirical laboratory utilised is seconded national experts in the European Commission. The survey and interview data presented demonstrates that the decision-making behaviour of seconded national experts includes a mix of departmental (portfolio), epistemic (expert) and supranational behaviour. The suspicion early voiced by Coombes (197…
