  3. 2. Study of the phase diagram of Zn symmetric chains

    Författare :Iman Mahyaeh; Eddy Ardonne; Supriya Krishnamurthy; Joost Slingerland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : In this thesis we study the phase diagrams of Zn symmetric chains. We start with investigating the topological phases of the Kitaev chain, a Z2 symmetric model, with long range couplings and a phase gradient. LÄS MER

  4. 3. Molecular overlayers on homogeneous and heterogeneous metal surfaces studied by core-level photoemission

    Författare :Maria Smedh; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectroscopy; core-level photoemission; electron energy loss spectroscopy; single crystal surfaces; metal surfaces; heterogeneous surfaces; adsorption; adsorbed molecules; hydrocarbons; molecular vibrations; carbon monoxide; adsorption sites; adsorption energy; diffusion; dissociation; Physics; Fysik; Fysicumarkivet A:2001:Smedh;

    Sammanfattning : The main topic of this thesis is the investigation of small molecules adsorbed on metal surfaces by means of core-level photoemission spectroscopy. The thesis consists of three parts; The first group of papers concerns the effects of internal molecular vibrations on the core-level photoemission spectra. LÄS MER

  5. 4. Parathyroid hormone for bone repair and implant fixation - Experiment in rats

    Författare :Ralf Skripitz; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PMMA-cement; torque; tensile tesst; Bone conduction chamber; PTH; rats; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Intermittently administered PTH is known to increase bone mass in osteoporosis models. We studied its effects in bone repair and implant fixation, using histological and mechanical techniques in rats. LÄS MER

  7. 5. Mortality and cancer incidence following cerebral angiography with thorotrast

    Författare :Ullakarin Nyberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Epidemiological studies are important tools in assessing radiation-related health effects in humans. The most common form of radiation exposure is low-dose alpha-radiation such as that from radon. However, the long-term health effects of low-dose radiation are incompletely known. LÄS MER
