  3. 2. Nerve tissue injury markers, inflammatory mechanisms and immunologic factors in lumbar disc herniation. Clinical and experimental studies

    Författare :Helena Brisby; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disc herniation; sciatica; intervertebral disc; nucleus pulposus; nerve root; neurofilament; S-100; cytokines; nitric oxide; glycosphingolipids.;

    Sammanfattning : The general concept for sciatic pain has for many decades been mechanical nerve root compression caused by a herniated disc. Recently evidence has indicated a more complex process, with a combination of mechanical and inflammatory/immunologic factors involved. LÄS MER

  4. 3. Exploring the nature of ISM turbulencein disc galaxies

    Författare :Timmy Ejdetjärn; Göran Östlin; Oscar Agertz; Garrelt Mellema; Troels Haugbølle; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; galaxies; galaxy; disc galaxy; star formation; ISM; interstellar medium; kinematics; dynamics; evolution; turbulence; numerical; Astronomy; astronomi; teoretisk astrofysik; Theoretical Astrophysics;

    Sammanfattning : Galaxy formation is a continuous process that started only a few hundred million yearsafter the Big Bang. The first galaxies were very volatile, with bursts of star formationand disorganised gas motions. LÄS MER

  5. 4. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping

    Författare :Lisbeth Hellström; Torbjörn Carlberg; Per Engstrand; Sören Östlund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood chipping; Chip formation; Digital Speckle Photography; Friction; Fracture Processes; Analytical model; Laboratory Wood Chipper; Force Measurement; Vibration Synthesis; Energy Efficiency; Chip Damage; TMP; CTMP; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER

  7. 5. Intervertebral disc degeneration in dogs

    Författare :Niklas Bergknut; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Back pain is common in both dogs and humans, and is often associated with intervertebral disc (IVD) degeneration. The IVDs are essential structures of the spine and degeneration can ultimately result in diseases such as IVD herniation or spinal instability. LÄS MER
