  2. 1. Energy Metabolic Stress Syndrome : Impact of Physical Activity of Different Intensity and Duration

    Author : Stefan Branth; Leif Hambraeus; Gunnar Ronquist; Mats Stridsberg; Lennart Kaijser; Uppsala universitet; []
    Keywords : Medicine; energy; ATP; metabolism; nutrition; body-composition; physical-activity; stress; insulin-resistance; ion-pumps; intracellular swelling and -shrinkage; taurine; reactive oxygen species; Medicin;

    Abstract : All living cell functions require an ongoing supply of energy derived from carbohydrates, lipids and proteins with their own pathways of breakdown. All of them end up in the oxidation of reduced coenzymes, yielding chemically-bound energy in the form of adenosine triphosphate (ATP). READ MORE

  4. 2. Psychophysiological reactions to experimental stress : relations to pain sensitivity, position sense and stress perception

    Author : Marina Heiden; Eugene Lyskov; Tohr Nilsson; Ulf Lundberg; Umeå universitet; []
    Keywords : public health; autonomic activity; cognitive-behavioral training; muscle oxygenation; physical activity; position sense; pressure-pain thresholds; sick leave; stress; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Stress and monotonous work contribute substantially to the development of chronic musculoskeletal disorders. Yet, the pathophysiological mechanisms underlying the process, particularly the involvement of autonomic regulation, remain unclear. READ MORE

  5. 3. Stress-induced BVOC emissions from forests in Sweden

    Author : Erica Jaakkola; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volatile organic compounds; Plant stress; Forests; Volatile emissions; spruce bark beetle infestations; ozone stress; wildfire recovery; Picea abies Norway spruce ; Betula pubescens ssp. czerepanovii; Pinus sylvestris Scots pine ; sweden;

    Abstract : A changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. READ MORE

  6. 4. On Multistage Analysis of Transonic Compressors: From Axisymmetric Throughflow Time-Marching to Unsteady Three-Dimensional Methods

    Author : Stephane Baralon; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; shock; time-marching; deterministic; average-passage; multistage; fan; axisymmetric; 3D; unsteady; transonic; viscous; body force; stress; singularity; perturbation; throughflow; mixing-plane; modelling; finite-volume;

    Abstract : A throughflow time-marching finite-volume solver, capable of computing viscous transonic multistage compressor flows with embedded shocks, is presented. The behavior of the blade model, based on the blade mean surface flow tangency condition, was investigated for transonic flows. READ MORE

  7. 5. Interaction Between Microgels and Oppositely Charged Proteins

    Author : Christian Johansson; Per Hansson; Brian Saunders; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microgel; protein; uptake; distribution; core-shell; colloidal stability; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis reports on interactions between microgels and oppositely charged proteins. Two types of negatively charged microgels are investigated: poly(acrylic acid) microgels of 60-80 µm in diameter, and colloidal poly(NIPAM-co-acrylic acid) microgels of around 1 µm in diameter.
