BACKGROUND Restless Legs Syndrome (RLS) is a common neurological movement disorder characterized by symptoms that follow a circadian pattern. Night and rotating shift work schedules exert adverse effects on functions of the human body by disturbing circadian rhythms, and they are known to cause sleep disturbances and insomnia. In this paper, we investigate the possible association between shift...

This work describes methodology for evaluating laboratory models of head impact biomechanics. Using this methodology, we investigated: how closely does twin-wire drop testing model head rotation in American football impacts? Head rotation is believed to cause mild traumatic brain injury (mTBI) but helmet safety standards only model head translations believed to cause severe TBI. It is unknown w...

This study examines manufacturer' perceptions of task and emotional conflict in domestic channels of distribution. Both are expected to depend on three antecedents (centralization, esprit de corps, and communication barriers) and to affect performance relative to competitors and manufacturer's satisfaction directly and indirectly through strategy quality. The results support a positive link bet...

Recognition of the friction stir welding process is growing in the aeronautical and aero-space industries. To make the process more available to the structural fabrication industry (buildings and bridges), being able to model the process to determine the highest speed of advance possible that will not cause unwanted welding defects is desirable. A numerical solution to the transient two-dimensi...

In low-temperature conditions of the interstellar medium pure HCN and mixtures of HCN with H2O and NH3 subjected to high-energy sources can be converted into different HCN polymers. In this context the HCN trimer – aminomalononitrile (AMN, H2NCH(CN)2) is an interesting candidate for astrophysical detection. We measured the rotational spectrum of AMN using the Lille BWO-based fast scan spectrome...

The pathological gait of children with cerebral palsy involves higher mechanical work, which limits their ability to function properly in society. Mechanical work is directly related to walking speed and, although a number of studies have been carried out in this field, few of them analysed the effect of the speed. The study aimed to develop standards for mechanical work during gait of children...
