Effect of mountain ultramarathon distance competition on biochemical variables, respiratory and lower-limb fatigue
2020
The study aimed at assessing the acute physiological effects of running a 65-km vs a 107- km mountain ultramarathon. Nineteen athletes (15 males and 4 females) from the shorter race and forty three athletes (26 males and 17 females) from the longer race were enrolled. Body weight, respiratory and lower limb strength were assessed before and after the race. Blood samples were obtained before, after and 24-h post-race. Body weight loss did not differ between races. A decrease in squat jump height (p<0.01; d = 1.4), forced vital capacity (p<0.01; d = 0.5), forced expiratory volume in 1 s (p<0.01; d = 0.6), peak inspiratory flow (p<0.01; d = 0.6) and maximal inspiratory pressure (p<0.01; d = 0.…
Endurance training in patients with chronic obstructive pulmonary disease: a comparison of high versus moderate intensity.
2000
Abstract Gimenez M, Servera E, Vergara P, Bach JR, Polu J-M. Endurance training in patients with chronic obstructive pulmonary disease: a comparison of high versus moderate intensity. Arch Phys Med Rehabil 2000;81:102-9. Purpose: To create a maximum tolerated 45-minute aerobic training program for patients with chronic obstructive pulmonary disease (COPD) and to compare its outcomes with those of commonly prescribed moderate exercise. Design: Prospective, randomized trial. Setting: A work physiology laboratory. Patients and Methods: The maximum exercise intensities that 7 COPD patients could sustain for 45 minutes were determined on a bilevel exercise ergometer. The patients then exercised …
L’inclusione vista dagli alunni: costruzione e validazione del questionario per rilevare la qualità inclusiva della scuola
2018
Molti studi nazionali e internazionali si sono concentrati sulla valutazione e sulla promozione della qualità inclusiva della scuola. Si tratta di un argomento complesso, che ha stimolato un ampio dibattito e una varietà di contributi che mettono in luce la necessità di uno strumento in grado di misurare la qualità inclusiva delle nostre scuole, per determinare l’evidenza empirica riguardo a questo tema. L’articolo presenta i risultati di una sperimentazione finalizzata alla redazione di un questionario per la rilevazione della qualità inclusiva del sistema scolastico percepita dagli alunni. Il questionario si pone come uno strumento di valutazione e autovalutazione che permette la misurazi…
Neutron ESR dosimetry through ammonium tartrate with low Gd content.
2014
This paper continues analyses on organic compounds for application in neutron dosimetry performed through electron spin resonance (ESR). Here, the authors present the results obtained by ESR measurements of a blend of ammonium tartrate dosemeters and gadolinium oxide (5 % by weight). The choice of low amount of Gd is due to the need of improving neutron sensitivity while not significantly influencing tissue equivalence. A study of the effect of gadolinium presence on tissue equivalence was carried out. The experiments show that the neutron sensitivity is enhanced by more than an order of magnitude even with this small additive content. Monte Carlo simulations on the increment of energy rele…
The SMILETRAP facility
1995
The SMILETRAP experimental set-up, a Penning trap mass spectrometer for highly charged ions, is described. Capture and observation of cyclotron frequencies of externally produced highly charged ions, rapid interchange of investigated and reference ions and measurements of the rotational kinetic energies are demonstrated. Mass measurements utilizing different charge states and species to verify the consistency of the measurements are presented. A relative uncertainty of about 10−9 is attained in comparisons between highly charged carbon, nitrogen, oxygen, neon and the singly charged hydrogen molecule.
Mesure du transport narratif dans le contexte d’une expérience de consommation transmédia
2018
This research offers a French narrative transportation scale measuring the experience of transmedia devices in the arts and cultural field. First, based on a literature review of the definition and measure of narrative transportation, a new scale is presented and defended. Second, a qualitative study is conducted. The dimensions of narrative transportation are confirmed and items are generated to measure it. Results from factorial analysis leading to a reliable and valid scale of narrative transportation lived by the cultural consumer through the use of a transmedia device are presented.
The n2EDM experiment at the Paul Scherrer Institute
2018
We present the new spectrometer for the neutron electric dipole moment (nEDM) search at the Paul Scherrer Institute (PSI), called n2EDM. The setup is at room temperature in vacuum using ultracold neutrons. n2EDM features a large UCN double storage chamber design with neutron transport adapted to the PSI UCN source. The design builds on experience gained from the previous apparatus operated at PSI until 2017. An order of magnitude increase in sensitivity is calculated for the new baseline setup based on scalable results from the previous apparatus, and the UCN source performance achieved in 2016.

Well GeHP detector calibration for environmental measurements using reference materials
2016
International audience; A well-type detector installed in the Modane underground Laboratory (LSM) can combine both low background and high detection efficiency and it is well suited for the analysis of small amounts of environmental samples. Reference materials such as IAEA-447 (moss-soil), IAEA-RG-Th1 and IAEA-RG-U1 were used for the detector calibration, owing to a chemical composition close to those of the environmental samples. Nevertheless , the matrix effects and the true coincidence summing effects must be corrected from the full energy peak efficiency (FEPE). The FEPE was performed for a wide range of energy by a semi-empirical method using Monte Carlo simulation (MCNP6), intended f…
Hadronic Shower Development in Iron-Scintillator Tile Calorimetry
2000
The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter uses a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behavior is obtained. The underlying radial energy densities for four depth segments and for the entire calorimeter have been reconstructed. A three-dimensional hadronic shower parametrization has been developed. The results presented here are useful for understanding the performance of iron-scintillator calorimeters, for developing fast simulations of hadronic showe…
