  2. 21. Insights into Materials Properties from Ab Initio Theory : Diffusion, Adsorption, Catalysis & Structure

    Author : Andreas Blomqvist; Rajeev Ahuja; Christopher Wolverton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Molecular dynamics; Diffusion; Catalysis; Adsorption; Random structure search; Hydrogen-storage materials; Phase-change materials; Defects and diffusion; Defekter och diffusion; Surfaces and interfaces; Ytor och mellanytor; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this thesis, density functional theory (DFT) calculations and DFT based ab initio molecular dynamics simulations have been employed in order to gain insights into materials properties like diffusion, adsorption, catalysis, and structure. In transition metals, absorbed hydrogen atoms self-trap due to localization of metal d-electrons. READ MORE

  4. 22. Genetic variation in genes involved in Abeta-degradation in Alzheimer disease

    Author : Mia Blomqvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alzheimer disease; SNPs; genotyping; association study; haplotype; linkage disequilibrium; association mapping;

    Abstract : Alzheimer disease (AD) is a neurodegenerative disorder that causes dementia among mainly elderly people and is increasing in prevalence in industrialized societies from 1 to 3 % in 60-65 year-olds to as much as 50 % by age 95. This disease is complex. Multiple genes are involved, and they potentially affect each other. READ MORE

  5. 23. Everyday living with persistent pain in old age. Pain and its alleviation as perceived by functionally dependent older persons and by staff

    Author : Kerstin Blomqvist; Institutionen för hälsovetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Medicin människa och djur ; content analysis.; typology; staff attitude; cognitive impairment; pain relief; pain assessment; pain; Elderly; nursing care;

    Abstract : This thesis explores everyday living with persistent pain from the perspectives of functionally dependent older persons in pain and of staff. A combination of qualitative and quantitative methods was chosen. Data were collected using interviews and tools for assessing pain. READ MORE

  6. 24. Ferroelectric Na0.5K0.5NbO3 as an electro-optic material

    Author : Mats Blomqvist; KTH; []
    Keywords : ferroelectrics; sodium potassium niobates; thin films; rf-magnetron sputtering; waveguiding; refractive index; prism coupling; dielectric tunability;

    Abstract : Ferroelectrics are a group of advanced electronic materialswith a wide variety of properties useful in applications suchas memory devices, resonators and filters, infrared sensors,microelectromechanical systems, and optical waveguides andmodulators. Among the oxide perovskite-structured ferroelectricthin film materials sodium potassium niobate or Na0. READ MORE

  7. 25. Magnetic resonance imaging of rectal tumours

    Author : Lennart Blomqvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Rectum; Neoplasms; Magnetic Resonance Imaging;

    Abstract : Cross sectional imaging techniques introduced during the last two decades have been increasingly used in the evaluation of patients with pelvic tumours. The extent of tumour - the tumour stage - at the time of diagnosis constitutes a guideline for both the immediate treatment and the follow-up of the patient. READ MORE
