  1. 1. On-line vectorcardiography in ischemic heart disease

    Författare :Peter Lundin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vectorcardiography; ischemia monitoring; coronary artery disease; exercise test; echocardiography; dobutamine; unstable angina pectoris; myocardial infarction; prognosis.;

    Sammanfattning : The clinical usefulness of continuous on-line vector cardiography (VCG) was assessed in 435 patients, admitted to the coronary care unit. The ability of 24-hour VCG monitoring to differentiate patients with or without ischemic heart disease (IHD), to provide long-term prognostic information and to predict results from a predischarge exercise test in patients with unstable angina pectoris or acute myocardial infarction (MI) was evaluated.

  3. 2. Laser Spectroscopic Investigations of Decay Properties in Stored Ions

    Författare :Peter Lundin; Sven Mannervik; Gillian Nave; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; fysik;

    Sammanfattning : Investigations and measurements of metastable states are in many ways very important. Spectroscopists, theorists and astrophysicists have all great interest and requirements regarding knowledge about such states and their properties. LÄS MER

  4. 3. Characterization and Correction of Analog-to-Digital Converters

    Författare :Henrik Lundin; Peter Händel; Mikael Skoglund; Paolo Carbone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital converter; ADC; correction; post-correction; look-up table; characterization; calibration; Signal processing; Signalbehandling;

    Sammanfattning : Denna avhandling behandlar analog-digitalomvandling. I synnerhet behandlas postkorrektion av analog-digitalomvandlare (A/D-omvandlare). A/D-omvandlare är i praktiken behäftade med vissa fel som i sin tur ger upphov till distorsion i omvandlarens utsignal. LÄS MER

  5. 4. Modulators of Saccharomyces cerevisiae cytochrome c oxidase : Implications for the regulation of mitochondrial respiration

    Författare :Camilla Rydström Lundin; Peter Brzezinski; Christoph von Ballmoos; Shelagh Ferguson-Miller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; cytochrome c; OXPHOS; membrane protein; kinetics; ligand-binding; electron transfer; Rcf1; respiratory supercomplexes; Saccharomyces cerevisiae; Biochemistry; biokemi;

    Sammanfattning : Oxidative phosphorylation in mitochondria is performed by enzyme complexes and electron carriers that reside in the inner membrane. It is now generally accepted that these respiratory enzyme complexes assemble into larger so-called supercomplexes. However, it is presently not known why, under which conditions or how these supercomplexes form. LÄS MER

  7. 5. Long-Term Posttraumatic Stress in Survivors from Disasters and Major Accidents

    Författare :Filip Arnberg; Tom Lundin; Christina Hultman; Per-Olof Michel; Hans Peter Søndergaard; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Posttraumatic stress disorder; Anxiety disorders; Transportation disasters; Motor vehicle accidents; Survivors; Children; Longitudinal studies; Posttraumatisk stresstörning; PTSD; ångeststörningar; katastrofer; transportolyckor; trafikolyckor; överlevande; barn; longitudinella studier; Psychiatry; Psykiatri;

    Sammanfattning : Disasters and major accidents are a significant cause of distress worldwide. High levels of posttraumatic stress can become chronic after severe and prolonged psychological trauma, raising concerns about the extent of adverse long-term consequences after single events. LÄS MER
