The present study was part of a large field study of physiological restitution after night-call duty, involving several sub-studies, each focusing on different aspects and potential negative health effects of the anaesthesiologists' work schedules: the impact on metabolic factors has been published earlier [ 17].
Third, in an animal study, the restitution of lung volume after suctioning was significantly slower during pressure-controlled ventilation than during volume-controlled ventilation [ 22].
The study shows that the coefficient of restitution for an oblique-impact cannot be regarded as a constant, and that the relations between the pre-impact state and the post-impact state are directly associated with the impact angle and the coefficient of contact friction between impacting bodies.
A two-dimensional multi-fluid Eulerian CFD model with closure laws according to the kinetic theory of granular flow has been applied to study the influence of the coefficient of restitution on the hydrodynamics of dense gas-fluidised beds.
However, the wall thickness of the ring only has a limited influence on both the rebounding velocity and the coefficient of restitution within the studied range.
The new model is well supported by the experimental measurements of compliance curves for elastic plastic materials and of coefficients of restitution from impact studies, and in elastic-perfectly plastic regimes is demonstrated to be more accurate than existing models found in the literature.
Short term evaluation of an ongoing prospective, interventional study of hand hygiene evaluation using restitution of results as primary mean of intervention showed a significant increase in the compliance with HH in a multicentre, regional hospital.
The solid fraction and shear rate do not vary with particle stiffness or coefficient of restitution over the range of values studied.
For the current study, according to Wan et al. (2008), the particle coefficient of restitution was set as 1.0 0.9 at the annular space.
Rolling friction, sliding friction and the coefficient of restitution are the critical parameters to be studied.
The influence of system parameters such as damping, coefficient of restitution, distribution of masses and clearance, etc., is studied for some extreme values of these parameters.
