  1. 11. Fatigue Anisotropy in Forged Components

    Författare :Cornelius Temmel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inclusion Cluster; Low Sulfur; Machinability; Inclusion; Manganese Sulfide; Quenching Crack; Forging; Isotropic Quality; Steel; Anisotropy;

    Sammanfattning : Ever-growing requirements on combustion engine efficiency of motor vehicles demand increasing service loads in powertrain components. Optimization of component material is therefore inevitable. A major detriment with many forged transmission components is their anisotropic mechanical behavior, not least during cyclic loading.

  3. 12. From other to self. Learning as Interactional Change

    Författare :Cathrin Martin; Sverker Lindblad; Fritjof Sahlström; Roger Säljö; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; learning; interaction; conversation analysis; participation; physiotherapy; Pedagogik; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : The aim of this study is to empirically develop the understanding of learning as changing participation. The point of departure is that learning is interactionally and situationally constituted and made visible as changes in participation. LÄS MER

  4. 13. Laser-Driven Plasma Waves for Particle Acceleration and X-ray Production

    Författare :Guillaume Genoud; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser plasma acceleration of electrons and protons; laser-wakefield acceleration; plasma waves; plasma-wiggler radiation; betatron radiation; laser guiding; laser pointing stabilisation;

    Sammanfattning : This thesis presents experimental results related to laser plasma accelerators. These rely on very different principles from conventional particle accelerators. LÄS MER

  5. 14. Connecting CMR and Physiology : Expanding the capabilities of cardiovascular magnetic resonance in quantifying physiology

    Författare :Felicia Seemann; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulär magnetresonanstomografi; Fysiologi; Atrioventrikulär klaffplansrörlighet; Mitralisflöde; Tryck-volym loopar; Kraft-längd loopar; Cardiovascular magnetic resonance; Physiology; Atrioventricular plane displacement; Transmitral flow; pressure-volume loops; Ventricular force-length loops;

    Sammanfattning : The assessment of cardiovascular physiology is crucial to facilitate clinical diagnostics, treatment, and research. Physiology and anatomy can be assessed noninvasively using cardiovascular magnetic resonance (CMR), a versatile and reliable medical imaging modality free from ionizing radiation. LÄS MER

  7. 15. Short- and long-term consequences of sport-related concussion

    Författare :Fredrik Vedung; Niklas Marklund; Gunnar Antoni; Elna-Marie Larsson; Jakob Johansson; Alexander Olsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sport-related concussion; Soccer; Traumatic brain injury; tau; neuroinflammation; cerebral blood flow; Neurokirurgi; Neurosurgery;

    Sammanfattning : Concussions are common in contact sports. Symptoms such as confusion and/or loss of consciousness following an impact to the head indicate that a sport-related concussion (SRC) has occurred. The symptoms normally resolve within 10-14 days following an SRC in adults although at least 10 % of athletes suffer from prolonged symptoms. LÄS MER
