Accuracy of Medical Oxygen Flowmeters: A Multicentric Field Study
août 2014, HE CondorcetArticle scientifiqueThe accuracy of 476 oxygen flowmeters was investigated using a thermal mass flowmeter in eight hospitals in France and Belgium. Different oxygen flow rates (2 to 15 l/min) were evaluated at the patient’s bed. When the sample was considered as a whole, the accuracy of delivered flow was acceptable but precision was poor. The variability of the delivered flow between devices was greater when a low ... -
Accuracy of oxygen flow delivered by compressed-gas cylinders in hospitals and prehospital emergency care
mars 2018, HE CondorcetArticle scientifiqueOxygen cylinders are widely used both in hospital and prehospital care. Excessive or inappropriate FIO2 may be critical for patients with hypercapnia or hypoxia. Moreover, over-oxygenation could be deleterious in ischemic disorders. Supplemental oxygen from oxygen cylinder should therefore be delivered accurately. The aim of this study was to assess the accuracy of oxygen flows for oxygen cylinder ... -

Article scientifiqueAbstract ; "Nowadays, the additive manufacturing of multifunctional materials is booming. The fused deposition modeling (FDM) process is widely used thanks to the ease with which multimaterial parts can be printed. The main limitation of this process is the mechanical properties of the parts obtained. New continuous-fiber FDM printers significantly improve mechanical properties. Another limitation ... -

Behaviour of pre-sintered Y-TZP during machining operations: Determination of recommended cutting parameters
06 février 2018, DEMARBAIX, Anthonin; Rivière-Lorphèvre, Edouard; Ducobu, François; Filippi, Enrico; Petit, Fabrice; Preux, Nicolas, HE Condorcet
Article scientifique"In this paper,the NF E 66-520-5 standard, dedicated to the determination ofthe optimal cutting parameters suitable for ductile material, is applied to the pre-sintered ceramic Y-TZP. The objective of the standard is to calculate the specific cutting energy of the forces created between the chosen tool and material during machining operation. Specific cutting energy is the energy required to remove ... -
Bilateral Strength Deficit Is Not Neural in Origin; Rather Due to Dynamometer Mechanical Configuration
18 décembre 2015, HE CondorcetArticle scientifiqueDuring maximal contractions, the sum of forces exerted by homonymous muscles unilaterally is typically higher than the sum of forces exerted by the same muscles bilaterally. However, the underlying mechanism(s) of this phenomenon, which is known as the bilateral strength deficit, remain equivocal. One potential factor that has received minimal attention is the contribution of body adjustments to ... -
Biodiversity of Fusarium species in ears and stalks of maize plants in Belgium
21 avril 2011, CARAHArticle scientifiqueIn order to investigate the pre-harvest contamination of maize plants by Fusarium species in Belgium, a three-year survey has been performed in five fields in which three hybrids differing in susceptibility to maize stalk rot were sampled at four different physiological stages. An extensive collection of 5,659 Fusarium isolates characterized at the species level was established during the 2005, 2006, ... -
Cannabidiol in sport : Ergogenic or else ?
20 mars 2020, HE CondorcetArticle scientifiqueIn the sports domain, cannabis is prohibited by the World Anti-Doping Agency (WADA) across all sports in competition since 2004. The few studies on physical exercise and cannabis focused on the main compound i.e. Δ9-tetrahydrocannabinol. Cannabidiol (CBD) is another well-known phytocannabinoid present in dried or heated preparations of cannabis. Unlike Δ9-tetrahydrocannabinol, CBD is non-intoxicating ... -
Cardiorespiratory responses during running and sport-specific exercises in handball players
mai 2009, HE CondorcetArticle scientifiqueTo determine whether a 4-a-side handball (HB) game is an appropriate aerobic stimulus to reach and potentially enhance maximal oxygen uptake (V˙O2max), and whether heart rate (HR) is a valid index of V˙O2 during a handball game. Nine skilled players (21.0 ± 2.9 yr) underwent a graded maximal aerobic test (GT) where V˙O2max and HR−V˙O2 relationship were determined. V˙O2, HR and blood lactate ([La]b) ... -
Construction of a Novel Chimeric Dextransucrase Fused to the Carbohydrate-Binding Module CBM2a
28 septembre 2021, HE CondorcetArticle scientifiqueLactic acid bacteria (LAB) have the potential to produce homoexopolysaccharides (HoPS). Their health benefits and physicochemical properties have been the subject of extensive research.
