Smelly primes – when olfactory primes do or do not work

In applied olfactory cognition the effects that olfactory stimulation can have on (human) behavior are investigated. To enable an efficient application of olfactory stimuli a model of how they may lead to a change in behavior is proposed. To this end we use the concept of olfactory priming. Olfactory priming may prompt a special view on priming as the olfactory sense has some unique properties ...

How do we know when patients sleep properly or why they do not?

The importance of adequate sleep for good health and immune system function is well documented as is reduced sleep quality experienced by ICU patients. In the previous issue of Critical Care, Elliot and co-workers present a well done, largest of its kind, single-center study on sleep patterns in critically ill patients. They base their study on the 'gold standard', the polysomnography technique...

When Do Endplates Work?

The effect of the gap between endplates and wing sections on aerodynamic lift and drag forces was investigated. This was studied in order to determine the maximum gap distance at which flow can still be considered two-dimensional, and tip effects can be neglected. A non-dimensional distance, λ, was defined as the ratio of gap distance, d, to laminar boundary layer thickness, δt,laminar , over t...
