  2. 1. Numerical studies on flows with secondary motion

    Author : Jacopo Canton; Philipp Schlatter; David Moxey; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear dynamical systems; instability; bifurcation; flow control; skin-friction reduction; Engineering Mechanics; Teknisk mekanik;

    Abstract : 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. READ MORE

  4. 2. On secondary prevention after acute coronary syndrome : -what, when, and who

    Author : Daniel Huber; Thomas Mooe; Nikolai Stenfors; Annika Rosengren; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; acute coronary syndrome; secondary prevention; nurse-led; statins; randomized controlled trial.; kardiologi; Cardiology;

    Abstract : 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.

  5. 3. Effects of Motion Sickness on Human Thermoregulatory Mechanisms

    Author : Gerard Nobel; Ola Eiken; Nigel A.S. Taylor; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motion Sickness; autonomic thermoregulation; behavioural thermoregulation; hypothermia; acetylcholine; histamine; Physiology; Fysiologi;

    Abstract : 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).

  6. 4. Lagrangian Particles in Turbulence and Complex Geometries

    Author : Azad Noorani; Philipp Schlatter; Johan Revstedt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct numerical simulation; wall turbulence; secondary motion; Teknisk mekanik; Engineering Mechanics;

    Abstract : 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. READ MORE

  7. 5. Visual demand in manual task performance - Towards a virtual evaluation

    Author : Tania Dukic; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; working posture; computer manikin software; motion; visual demand;

    Abstract : 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. READ MORE
