  3. 8. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

    Detta är en avhandling från Umeå : Umeå University

    Författare :Guilherme Hilgert Elcadi; Högskolan i Gävle.; Högskolan i Gävle.; Umeå universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi; Physiology;

    Sammanfattning : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. LÄS MER

  4. 9. Improved farm soil mapping using near infrared reflection spectroscopy

    Detta är en avhandling från Umeå : Umeå University

    Författare :Johanna Wetterlind; Sveriges lantbruksuniversitet.; [2009]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Information on soil texture, soil organic matter content (SOM), nutrient status and pH is fundamental for efficient crop production and for minimising negative effects on the environment. Farmers obtain this information, on which decisions on fertiliser and lime requirements are based, through farm soil mapping. LÄS MER

  5. 10. Modelling of Kraft Cooking Kinetics Using Near Infrared Spectroscopy

    Detta är en avhandling från Karlstad : Karlstad University Studies

    Författare :Niclas Andersson; [2003]
    Nyckelord :;

    Sammanfattning : A kinetic model describing the kraft cooking degradation reactions for softwood lignin and carbohydrates was developed in this thesis. The model satisfactorily predicted the data for modified as well as conventional cooking schemes, something which eluded earlier published models. LÄS MER
