Plasma asymmetric dimethylarginine concentrations are not related to differences in maximal oxygen uptake in endurance trained and untrained men
22 novembre 2018, HE CondorcetArticle scientifiqueAsymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthesis that could limit oxygen (O2) delivery in the working skeletal muscles by altering endothelium‐dependent vasodilatation. Exercise capacity is associated with plasma ADMA concentrations in patients with cardiovascular diseases, but this issue has still not been investigated in healthy subjects. We aimed to ... -
A new formula for predicting the fraction of delivered oxygen during low-flow oxygen therapy
décembre 2018, HE CondorcetArticle scientifiqueDuring O2 therapy at low flow in patients who breathe spontaneously, the fraction of delivered O2 (FDO2) is unknown. In recent years, FDO2 prediction formulas have been proposed. However, they do not take into account the effect of inspiratory flow (V̇I) on the FDO2. The aim of this study was to validate a new FDO2 prediction formula, which takes into account the V̇I and compares it with other FDO2 ... -

Chemical etching as a finishing process for electron beam melting (EBM) parts
02 juillet 2019, Dolimont, Adrien; DEMARBAIX, Anthonin; Ducobu, François; Rivière-Lorphèvre, Edouard, HE Condorcet
Acte de conférence ou de colloque"The goal of this research is to analyze the impact of chemical etching on parts produced by electron beam melting. Given that the surface conditions are poor (Ra between 25 to 35 µm), an enhancement of these is asked. Dimensional and surface measurements were realized on conceived parts. Different exposure times were tested. The impact of these times on surface quality was evaluated. To help ... -
Thorpe tube and oxygen flow restrictor : what's flow accuracy ?
10 février 2020, HE CondorcetArticle scientifiqueOxygen gas flowmeters (OGF) are used to regulate the oxygen flow in acute and chronic care. In hospitals, Thorpe tubes (TT) are the classical systems most used for delivering oxygen. In recent years, the oxygen flow restrictor (OFR) has appeared. These devices use a series of calibrated openings in a disk that can be adjusted to deliver different flow rates. These devices have a reputation for ... -
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 ... -
