    Sammanfattning : The rapid development of wearable technology has provided opportunities to ergonomics research and practice with new ways for workload measurements, data analytics, risk assessment and intervention. This thesis aims at developing and evaluating methods using wearable technologies to assess physical risk factors at work, and further to give feedback to employees to improve their work techniques.

  3. 22. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging

    Författare :Anna Nestorson; Lars Järnström; Anders Leufvén; Caisa Andersson; José M. Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. LÄS MER

  4. 23. Blood volume expansion following supramaximal exercise : occurrence and contribution to maximal oxygen uptake

    Författare :Mirko Mandić; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Previously published research using various types of exercise has shown that central hemodynamic factors such as blood volume (BV) and maximal cardiac output (Qmax) are of large importance in the mediation of improvements in VO2max. Whether this is true for adaptations induced by sprint-interval training (SIT) is unclear. LÄS MER

  5. 24. The role of reactive oxygen species in traumatic brain injury : Experimental studies in the rat

    Författare :Niklas Marklund; Uppsala universitet; []
    Nyckelord :Medical sciences; Apoptosis; CBF; controlled cortical contusion injury; 3; 4-dihydroxybenzoate; fluid percussion injury; glucose; 4-hydroxybenzoate; microdialysis; Morris Water Maze; neuroprotection; nitrones; PBN; rat; reactive oxygen species ROS ; salicylate; S-PBN; TBI; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Neurosurgery; neurokirurgi;

    Sammanfattning : Traumatic brain injury (TBI) is a major cause of mortality and disability. As common sequelae in survivors of TBI are disabling functional, emotional and cognitive disturbances, improved treatment of TBI patients is urgently needed. At present, no neuroprotective pharmacological treatment exists. LÄS MER

  7. 25. Quantitative diffuse reflectance spectroscopy : myocardial oxygen transport from vessel to mitochondria

    Författare :Tobias Lindbergh; Tomas Strömberg; Henrik Ahn; Marcus Larsson; Lise Lyngsnes Randeberg; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction.
