Unlabelled: To determine the relationships between limiting factors and neuromuscular activity during a self-paced 20-km cycling time trial and evaluate the effect of environmental conditions on fatigue indices.
Methods: Ten endurance-trained and heat-acclimated athletes performed in three conditions (ambient temperature, relative humidity): HUMID (30 °C, 90%), DRY (35 °C, 46%) and NEUTRAL (22 °C, 55%). Voluntary muscular contractions and electromagnetic stimulations were recorded before and after the time trials to assess fatigue.
Objectives: In the last 30 years, opioid maintenance treatment prescription (OMT) has changed patients' and also changed physicians' practices. General practitioners (GPs) have to deal with patients on OMT who are in acute pain. The objective of this qualitative study was to explore medical care challenges and solutions identified by GPs in the management of acute pain among patients receiving OMT.

This mechanism, originally demonstrated with four continuous-wave pumps and a signal wave, is based on four-wave mixing and enables to convert the two quadrature components of the signal to different frequencies. In this work, we derive a set of two simple equations to describe this mechanism and find analytic solutions.
