  1. 21. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors

    Författare :Rasoul Nilforoush; Lennart Elfgren; Norbert Randl; Karin Lundgren; Manouchehr Hassanzadeh; Richard Malm; Lars-Erik Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Headed anchor; Anchor bolt; Adhesive anchor; Concrete cone breakout; Concrete splitting; Pullout loading; Size effect; Member thickness; Anchor head size; Orthogonal surface reinforcement; Concrete Strength; High-strength concrete; Cracked concrete; Steel fiber-reinforced concrete; Sustained loading; Creep behavior; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. LÄS MER

  3. 22. Improving healthcare information systems : A key to evidence based medicine

    Författare :Hanife Rexhepi; Rose-Mharie Åhlfeldt; Anne Persson; Karin Hedström; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Process orientation; Knowledge management; Healthcare; Evidence based medicine; Information Systems; Informationssystem IS ;

    Sammanfattning : Delivering good quality care is a complex endeavor that is highly dependent on patient information and medical knowledge. When decisions about the care of a patient are made, they must, as far as possible, be based on research-derived evidence rather than on clinical skills and experience alone. LÄS MER

  4. 23. The Effect of Various Dopants on Diamond Growth : A Combined Experimental & Theoretical Approach

    Författare :Yiming Zou; Karin Larsson; Mats Boman; Petter Persson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diamond; Growth rate; HFCVD; Doping; Activation energy; Reaction order;

    Sammanfattning : Diamond is a unique material with many exceptional properties. It has therefore been proven to be an important material for many applications. Moreover, the introduction of dopant species into the gas phase during the CVD growth process has been shown to strongly influence not only the properties and morphology of diamond, but also the growth rate.

  5. 24. CYP2C19 catalyzed drug metabolism in different populations

    Författare :Karin Herrlin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :CYP2C19; drug metabolism; cytochrome P450; mephenytoin; omeprazole; proguanil chloroguanide ; citalopram; debrisoquine; CYP2D6; gene duplication; pharmacogenetics;

    Sammanfattning : Metabolism catalyzed by the cytochrome P450 enzyme CYP2C19 varies between individuals, who can be either efficient (EM) or poor metabolizers (PM). In this thesis the metabolism of four different CYP2C19 substrates (citalopram, mephenytoin, omeprazole, and proguanil) was investigated in vivo in Africans (Ethiopians an Tanzanians) an in Swedish is Caucasians.
