Risonanza stocastica non dinamica in una popolazione di Nezara Viridula (L.)
2009
In questo lavoro viene studiato l’effetto del rumore sul comportamento, durante il periodo di accoppiamento, di individui di Nezara viridula (L.). Analizzando la risposta di insetti maschi a segnali sotto soglia, prodotti da individui di sesso femminile, si osserva, in presenza di una sorgente esterna di rumore bianco Gaussiano, un’attivazione “comportamentale”, con un andamento non monotono in funzione dell’intensit`a di rumore, chiara indicazione della presenza di risonanza stocastica non dinamica. Lo studio `e ripetuto utilizzando una sorgente di rumore colorato. Infine, i risultati sperimentali vengono riprodotti attraverso un modello a soglia “morbida”, in cui la funzione di cross-corr…
Role of Gender, Enjoyment, Perceived Competence, and Fundamental Movement Skills as Correlates of the Physical Activity Engagement of Finnish Physica…
2010
The aim of the study was to investigate the relationships between enjoyment, perceived physical activity competence, fundamental movement skills, and physical activity engagement of Grade 7 students participating in Finnish physical education. A secondary aim of the study was to examine gender differences in all assessed variables. The participants of the study were 404 Grade 7 students aged 13 years. The sample comprised 210 girls and 194 boys, who were involved in 23 classes taught by 10 physical education teachers at three secondary schools. Physical activity engagement, enjoyment, and perceived physical activity competence were assessed by self-report questionnaires. Locomotor skill was…
Directly measured and self-reported physical activity in a sample of Finnish secondary school students
2012
Background: Previous studies based on self-reports show that a majority of children and adolescents in Western countries fail to achieve the recommendation of 60 minutes moderate to vigorous physical activity (PA) on a daily basis. The specific aim of the study was to analyze the relationship between directly measured and self-reported PA in a cross-sectional sample of Finnish secondary school students. Moreover, how large proportion of adolescents accumulate at least 60 minutes of moderate to vigorous PA on a daily basis using self-reports and direct measure scores. Methods: Participants were recruited from a secondary school located in Northeast Finland. The sample comprised 96 students (…
BASE-STEP: A transportable antiproton reservoir for fundamental interaction studies
2023
Currently, the only worldwide source of low-energy antiprotons is the AD/ELENA facility located at CERN. To date, all precision measurements on single antiprotons have been conducted at this facility and provide stringent tests of the fundamental interactions and their symmetries. However, the magnetic field fluctuations from the facility operation limit the precision of upcoming measurements. To overcome this limitation, we have designed the transportable antiproton trap system BASE-STEP to relocate antiprotons to laboratories with a calm magnetic environment. We anticipate that the transportable antiproton trap will facilitate enhanced tests of CPT invariance with antiprotons, and provide…
