D’une pyramide en origami à la tangente de 22,5°
2017, HE Léonard de VinciArticle scientifiqueDans cet article, nous invitons le lecteur à se pencher sur une pyramide droite à base carrée réalisée en origami. Nous verrons comment la recherche des dimensions de la pyramide en fonction de celles de la feuille de papier peut amener à déterminer la valeur exacte de tangente de 22,5◦, sans utiliser la formule trigonométrique classique de la tangente d’un angle moitié. -

Early detection of diving-related cognitive impairment of different nitrogen-oxygen gas mixtures
30 juin 2019, Lafère, Pierre; ; ; Matity, Luba; Guerrero, François; BALESTRA, Costantino
, HE Bruxelles Brabant
Article scientifiqueNTRODUCTION: Cognitive impairment related to inert gas narcosis (IGN) is a threat to diving safety and operations at depth that might be reduced by using enriched air nitrox (EANx) mixtures. Using critical flicker fusion frequency (CFFF), a possible early detection of cognitive abilities/cerebral arousal impairment when breathing different oxygen (O2) fractions was investigated. METHODS: Eight male ... -
Early Endothelial Dysfunction in Type 1 Diabetes Is Accompanied by an Impairment of Vascular Smooth Muscle Function: A Meta-Analysis
05 mai 2020, Lespagnol, Elodie; Dauchet, Luc; Pawlak-Chaouch, Mehdi; BALESTRA, Costantino; Berthoin, Serge; Feelish, Martin; Roustit, Mathieu; Boissiere, Julien; Fontaine, Pierre; Heyman, Elsa, HE Bruxelles Brabant
Article scientifiqueBackground: A large yet heterogeneous body of literature exists suggesting that endothelial dysfunction appears early in type 1 diabetes, due to hyperglycemia-induced oxidative stress. The latter may also affect vascular smooth muscles (VSM) function, a layer albeit less frequently considered in that pathology. This meta-analysis aims at evaluating the extent, and the contributing risk factors, of ... -

Ecological, morpho-agronomical, and nutritional characteristics of Sulla flexuosa (L.) Medik. ecotypes
16 août 2023, HE CondorcetArticle scientifique"The present work was part of assessing wild genetic plant resources of forage interest in Northern Morocco and aimed to study the agro-morphology and nutritional value of Sulla fexuosa (L.) Medik. (Hedysarum fexuosum L.) ecotypes. The seeds of twenty-one wild S. fexuosa (L.) Medik. ecotypes were collected from 21 sites. The edaphic and climatic characteristics of the collection sites were studied ... -
Ecological, morpho‑agronomical, and bromatological assessment of sorghum ecotypes in Northern Morocco
20 septembre 2023, HE CondorcetArticle scientifique"Sorghum Bicolor is a cereal used for grains as feed and food, mainly cultivated in dry areas. To study the possibilities of increasing its cultivation for feed purposes, ecological, morpho-agronomical, and bromatological characterization of some local ecotypes was conducted as the first steps toward selecting better cultivars. Indeed, twenty-one ecotypes were collected from farms in Northern Morocco ... -

EEG dynamics and neural generators of psychological flow during one tightrope performance
24 juillet 2020, HE CondorcetArticle scientifiquePsychological “flow” emerges from a goal requiring action, and a match between skills and challenge. Using high-density electroencephalographic (EEG) recording, we quantified the neural generators characterizing psychological “flow” compared to a mindful “stress” state during a professional tightrope performance. Applying swLORETA based on self-reported mental states revealed the right superior ... -
EEG-based brain-computer interface for alpha speed control of a small robot using the MUSE headband
28 septembre 2020, HE CondorcetActe de conférence ou de colloqueNon-invasive BMI applications are increasingly used in different contexts ranging from industrial, clinical and gaming. After having tested the difference between a classical EEG recorder with electroconductive gel (ANT system) and the MUSE EEG headband, we studied the BCI performances of the later during the control of a small robot. We demonstrated that the participants were able to successfully ... -

The effect of a passive stretch training protocol on performance during a drop jump in humans
30 mars 2013, Levenez, Morgan; ; Bottero, Antoine; ; Tinlot, Arnaud; BALESTRA, Costantino; Provyn, Steven, HE Bruxelles Brabant
Article scientifiqueOur study's aim is to show how a five-week stretch training protocol, based on passive stretching, can change muscle performance during a drop jump (stretch shortening cycle). METHODS: This study observes in 8 healthy subjects (four males and four females), the effect of a 5-week passive stretch training protocol on the stretch shortening cycle (SSC) during the performance of a drop jump, and identify ... -

Effect of a single, open-sea, air scuba dive on human micro- and macrovascular function
15 août 2013, ; Pontier, Jean-Michel; BALESTRA, Costantino; Mazur, Aleksandra; Wang, Qiong; Buzzacott, Peter; Theron, Michaël; Mansourati, Jacques; Guerrero, François, HE Bruxelles Brabant
Article scientifiquePurpose: Previous studies have shown that bubble formation induced endothelial damage on conduit arteries. We aim to evaluate the effect of diving on microvascular and macrovascular function. Methods: Nine divers took part in a SCUBA dive at 30 msw (400 kPa), for 30 min of bottom time. Pre- and post-dive, they underwent an assessment of endothelial-dependent (acetylcholine) and endothelial-independent ...
