  1. 1. Oxidation and Reconstructions of Alloy Model Catalysts : Platinum-Rhodium and Palladium-Gold

    Författare :Helen Edström; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alloying; APXPS; Bimetallic Catalysts; Heterogeneous Catalysis; HESXRD; Oxidation; Oxide Formation; Palladium-Gold; Platinum-Rhodium; Surface Reconstruction; Fysicumarkivet A:2023 Edström;

    Sammanfattning : Alloys and bimetallic systems have shown many advantages in heterogeneous catalysis, but the details of their catalytic functions are not always known. For instance, the atomic details about surface reconstructions under catalytic reaction conditions, or which phases that are high-active or low-active. LÄS MER

  3. 2. Antimicrobial activity of human seminal plasma and seminal plasma proteins

    Författare :Anneli Edström; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; semenogelin; antibacterial peptides; antifungal peptides; seminal plasma; antimicrobial peptides; vaginal pH; beta-microseminoprotein; peptides;

    Sammanfattning : Seminal plasma is semen without the spermatozoa. Human seminal plasma is a complex mixture of secretions from the sex accessory glands, mainly the seminal vesicles and the prostate. Seminal plasma has high protein content and it also contains ions, sugars and low molecular weight components. LÄS MER

  4. 3. A theoretical study of mass transport processes on TiN(001) and mechanical properties of TiN- and VN-based ternaries

    Författare :Daniel Edström; Valeriu Chirita; Lars Hultman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns computer simulations, using classical molecular dynamics, of transport processes related to TiN(001) growth. It is motivated from the challenge to understand transport processes at the atomic scale responsible for crystal and film growth and their different growth modes. LÄS MER

  5. 4. Sarcopenia

    Författare :Erik Edström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Aging; sarcopenia; atrophy; regeneration; innervation; dietary restriction;

    Sammanfattning : Sarcopenia (Greek; sarcos: flesh, and penia: poverty) is the pronounced muscle loss that affects the aging population. Sareopenia of the leg muscles results in loss of independence and increased morbidity in the elderly. Emphasizing hind limb motor function, this thesis investigates different aspects of aging and sarcopenia in a rodent model. LÄS MER

  7. 5. Hur styrs försvarsmakten? : Politisk och militär syn på försvarsdoktrin under 1990-talet

    Författare :Håkan Edström; Steve Lindberg; Umeå universitet; []
    Nyckelord :statskunskap; political science; Statsvetenskap med inriktning mot strategi och säkerhetspolitik;

    Sammanfattning : Is there a common notion amongst the political and military leadership in Sweden on how to defend the country? Several events in the arena of international politics during the 20th century argue for the importance of coherence between political and military thinking. Different focus during peacetime has subsequently caused fatal consequences in times of war. LÄS MER
