1. Numerical studies on flows with secondary motion
Sammanfattning : This work is concerned with the study of flow stability and turbulence control - two old but still open problems of fluid mechanics. The topics are distinct and are (currently) approached from different directions and with different strategies. LÄS MER
2. On secondary prevention after acute coronary syndrome : -what, when, and who
Sammanfattning : BackgroundCardiovascular disease, of which coronary heart disease constitutes the lion’s share, is the leading cause of premature morbidity and mortality worldwide. Management of the condition has evolved rapidly in recent decades, and mortality has more than halved in the western world. LÄS MER
3. Effects of Motion Sickness on Human Thermoregulatory Mechanisms
Sammanfattning : The presented studies were performed to investigate the effects of motion sickness (MS) on human autonomic and behavioural thermoregulatory mechanisms during cold stress and in a thermoneutral environment. The roles of histaminergic and cholinergic neuron systems in autonomic thermoregulation and MS-dependent dysfunction of autonomic thermoregulation were studied using a histamine-receptor blocker, dimenhydrinate (DMH), and a muscarine-receptor blocker, scopolamine (Scop).

4. Lagrangian Particles in Turbulence and Complex Geometries
Sammanfattning : Wall-dominated turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the arrier and the dispersed phase is elevated to a higher level introducing geometrical complexities such as curved walls. LÄS MER
5. Visual demand in manual task performance - Towards a virtual evaluation
Sammanfattning : Visual information is crucial for carrying out motor activities. However, knowledgeabout the effects of visual demand on the performance of manual tasks is not welldocumented. Visual determinants must be identified in order to be used in visualisationand simulation tools (e.g. LÄS MER
