  1. 1. Z2-Gauge Theory with Matter : Dispersive behaviour of a dimer in a 1+1-dimensional lattice

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Filip Ekblom; [2023]
    Nyckelord :Spin chain; Ising model; Dimer; Lattice; Lattice gauge theory;

    Sammanfattning : The intention with this thesis is to investigate a dimer in a spin chain. Inorder to do that, a model from Z2-gauge theory is taken as the theoretical motivation to construct a discrete lattice with Ising spin properties. A dimer is then allowed to exist indirectly in the empty space between sites. LÄS MER

  3. 2. Is the media just a copycat or a watchdog?

    Kandidat-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Anna Raunio; Alice Johansson; Emilia Külick; [2023]
    Nyckelord :Business and Economics;

    Sammanfattning : Nyckelord: Media, väktare, vakthund, informationsförmedlare, tystnad Studiens syfte: Syftet med studien är att utvärdera hur väl media uppfyller sin roll som väktare i sin vardagliga rapportering i Sverige. För att ta reda på detta undersöks även om det skiljer sig mellan affärspress och annan media, samt vad det innebär för medias väktarroll när de inte rapporterar alls. LÄS MER

  4. 3. Studies of the axial-vector transition form factors of the process Ω− → W−Ξ0 in chiral perturbation theory

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Hélène De Munck; [2023]
    Nyckelord :Transition form Factors; Next-to-next-to-leading order; chiral perturbation theory; axial-vector; Ω− → W−Ξ0;

    Sammanfattning : This work is included in a broader research of the hadron theory group of Uppsala University and its collaborators tackling the quest for an understanding of the quark distribution inside hadrons by joining threedifferent approaches of QCD namely chiral perturbation theory, dispersion theory and lattice QCD. This thesis contributes by computing in chiral perturbation theory, the quark-masses dependence of form factors. LÄS MER

  5. 4. The impact of family ownership on capital structure - Empirical evidence from Swedish family firms

    Master-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Hassan Khadhem; Safaa Ishak; [2023]
    Nyckelord :Family ownership; capital structure; corporate governance; agency theory.;

    Sammanfattning : This study investigates how family ownership affects firms' financing decisions in Sweden. The study uses data on publicly listed firms in Sweden from 2014-2019 with 730 firm-year observations. Sweden has a significant portion of family firms and a business environment where control-enhancing mechanisms are used to a large extent. LÄS MER

  7. 5. Utvärdering av ny farmaceutisk arbetsmetod för förstärkt läkemedelsinformation från patientperspektiv

    Master-uppsats, Uppsala universitet/Institutionen för farmaci

    Författare :Erik Andersson; [2022]
    Nyckelord :;

    Sammanfattning : Background and objectiveFollowing signs of lacking drug related information for inpatients in the orthopedic care unit of Mälarsjukhuset, Eskilstuna, a clinical pharmacist intervention comprised of bedside reconciliation for newly prescribed drugs prior to discharge combined with information leaflets for home use was enacted by the care unit. The aim of this study was to evauluate this intervention from the patients perspective to identify areas in need of improvement DesignA mixed method approach consisting of a questionnaire based on ”Nationella patientenkäten” and telephone interviews was used.
