  1. 11. Pharmacogenetic studies of thiopurines : focus on thiopurine methyltransferase

    Författare :Malin Lindqvist Appell; Michel Eichelbaum; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Pharmacogenetics represents the study ofvariability in drug response due to genetic variations. The thiopurines (6-mercaptopurine, 6-thioguanine and azathioprine) are prodrugs which require metabolic transformation to exert effect. LÄS MER

  3. 12. Mechanical Properties of Semi-Solid Al Castings : Role of Stirring

    Författare :Qing Zhang; Anders E.W. Jarfors; Stefan Jonsson; Jens Bergström; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; aluminium alloys; stirring; segregation; porosity; oxides; ductility; fatigue performance;

    Sammanfattning : Semi-solid metal (SSM) casting has been widely used in automotive industries to reduce the weight. In RheoMetalTM process which is one of the variations of SSM, the slurry fabrication can be finished within 30 second and can the slurry making process can be integrated into a high pressure die casting (HPDC) route without significant adjustments, making the process a promising alternative for industrial application.

  4. 13. The effect of anti-slip devices on pedestrian safety : method development and practical test

    Författare :Glenn Berggård; Christer Hydén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Sammanfattning : Every winter, more than 100,000 pedestrians in the Nordic countries receive medical treatment as a result of falls on slippery surfaces. In addition, the risk of injury reduces interest in outdoor activities during the wintertime. LÄS MER

  5. 14. Reading the Sky : From Starspots to Spotting Stars

    Författare :Urban Eriksson; Cedric Linder; John Airey; Andreas Redfors; Edward E. Prather; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Astrometry; Astronomy Education Research; Disciplinary Discernment; Extrapolating three-dimensionality; Reading the Sky; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : This thesis encompasses two research fields in astronomy: astrometry and astronomy education and they are discussed in two parts. These parts represent two sides of a coin; astrometry, which is about constructing 3D representations of the Universe, and AER, where for this thesis, the goal is to investigate university students’ and lecturers’ disciplinary discernment vis-à-vis the structure of the Universe and extrapolating three-dimensionality.
