  1. 6. Controlled drinking : a viable treatment goal in alcohol use disorder?

    Författare :Stina Ingesson Hammarberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alcohol use disorders (AUD) has one of the largest treatment gaps among psychiatric diagnoses, with a treatment coverage of 10 to 20 %. One of the key contributing factors is the lack of treatments aiming for controlled drinking (CD) instead of abstinence. LÄS MER

  3. 7. Synthesis of carbon-covered iron nanoparticles by photolysis of ferrocene

    Författare :Karine Elihn; Knut Deppert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; iron; carbon; nanoparticle; ferrocene; laser-assisted CVD; particle size; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : One important driving force in nanotechnology today is the change which can be made in the properties of a material when the dimensions of its individual building blocks are decreased below approximately 100 nm. Such small building blocks, typically nanoparticles, may induce new and unique properties compared to those of the corresponding bulk material. LÄS MER

  4. 8. Cryptic Orogeny : uplift of the Al Hajar Mountains at an alleged passive margin

    Författare :Reuben Johannes Hansman; Ring Uwe; Joachim Jacobs; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; uplift; mountains; structural; low-temperature; thermochronology; dating; fission-track; U-Th He; U-Pb; calcite; structure-from-motion; photogrammetry; UAV; trishear; fault-propagation; Hafit; Al Hajar Mountains; United Arab Emirates; Oman; Geology; geologi;

    Sammanfattning : Mountains evolve and grow because of the large forces that occur from the collision of tectonic plates. Plate boundaries change and move through time, and regions that were once stable, shallow-marine environments can be dragged into subduction zones and get transformed into vast mountain ranges.

  5. 9. Competing logics in hospital mergers : the case of the Karolinska University Hospital

    Författare :Soki Choi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Today there is no doubt that mergers have permeated all sectors of society, including health care. Starting in the US, extensive waves of hospital mergers occurred at a record pace in the 1980’s typically justified by promising dramatic financial and operational improvements. LÄS MER

  7. 10. Genetic response to pollution in sticklebacks; natural selection in the wild

    Författare :Emma Lind; Mats Grahn; Marjorie Oleksiak; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Population genomics; genome scan; divergent selection; Gasterosteus aculeatus; Baltic Sea; pollution; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : The last century, humans have been altering almost all natural environments at an accelerating rate, including the Baltic Sea that has highly eutrophicated areas and many coastal industries such as Pulp-mills. For animals living in a habitat that changes there are basically two alternatives, either to cope with the change or become locally extinct. LÄS MER
