  2. 1. The endocannabinoid system : a translational study from Achilles tendinosis to cyclooxygenase

    Author : Emmelie Björklund; Christopher Fowler; Peter Zygmunt; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The endogenous cannabinoids anandamide (arachidonoyl ethanolamide, AEA) and 2-arachidonoyl glycerol (2-AG) exert their effect by activating cannabinoid receptors (CB). These receptors mediate a broad range of physiological functions such as beneficial effects in pain and inflammation, although little is known about the expression of CB receptors in human pain conditions.

  4. 2. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Author : Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. READ MORE

  5. 3. Wind Turbine Drive Train System Dynamics ; Multibody Dynamic Modelling and Global Sensitivity Analysis

    Author : Saeed Asadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global sensitivity analysis; Model validation; Multibody dynamics system mod-elling; Gearbox modelling; Kinematic constraints; Bearing defects detection; Wind turbine drive train dynamics; Floating reference frame;

    Abstract : To facilitate the design and production of highly efficient and reliable wind turbine drive trains, this thesis deals with the mathematical modelling and analysis of drive train system dynamics. The drive train is considered as the subsystem of the wind turbine that transfers mechanical power from the rotor hub to the generator, and thereby plays an important role in the system dynamics and the efficiency of wind turbine operation.

  6. 4. The role of estrogen receptors in the auditory system

    Author : Konstantina Charitidi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Both laboratory and clinical studies have previously demonstrated estrogenic effects on auditory function. The overall scope of this study was to investigate the physiological and molecular involvement of estrogens and estrogen receptors alpha (ERα) and beta (ERβ) in hearing physiology. READ MORE

  7. 5. Interpolymer complexation of a polymer brush

    Author : John Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional materials; macromolecular gating; Interpolymer complex; nanopores; polymer brush; pH responsive;

    Abstract : Controllable macromolecular gating between nanoscopic compartments is of high interest for single molecule studies of biological macromolecules. By definition, a good macromolecular gate should completely stop biomolecules, such as proteins, from crossing between compartments in its closed state while letting them pass in its open state.
