  1. 21. Identification of pathophysiological and prognostic biomarkers in different types of myocardial infarction

    Författare :Marcus Hjort; Bertil Lindahl; Kai M. Eggers; Helge Rørvik Røsjø; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial infarction; biomarker; pathophysiology; prognosis; MINOCA; STEMI; NSTEMI; hjärtinfarkt; biomarkör; patofysiologi; prognos; MINOCA; STEMI; NSTEMI; Cardiology; Kardiologi;

    Sammanfattning : The pathophysiological mechanisms of myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) are largely unknown. Analogous, differences in pathobiology between ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) are incompletely understood. LÄS MER

  3. 22. Biomarkers of Renal Function in Acute Coronary Syndromes

    Författare :Axel Åkerblom; Stefan James; Lars Wallentin; Torbjörn Omland; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cystatin C; glomerular filtration rate; GFR; creatinine; acute coronary syndrome; ACS; kidney; renal; mortality; death; myocardial infarction; Cardiology; Kardiologi; Medicin; Medicine; Internal Medicine; Internmedicin;

    Sammanfattning : The thesis aimed to investigate cystatin C and creatinine-based estimates of glomerular filtration rate (eGFR), both at admission and during follow-up, on the combined endpoint of cardiovascular death and myocardial infarction in patients with acute coronary syndrome (ACS). We also evaluated two cystatin C assays and assessed genetic determinants of cystatin C concentrations. LÄS MER

  4. 23. Hydrodynamic Modelling for a Point Absorbing Wave Energy Converter

    Författare :Jens Engström; Jan Isberg; Mats Leijon; Antonio Sarmento; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Ocean wave energy; Point absorber; Wave energy converter; Wave energy transport; Polychromatic wave; Linear generator; Resonance; Finite depth; Modelling; Engineering Science with specialization in Electronics; Teknisk fysik med inriktning mot elektronik;

    Sammanfattning : Surface gravity waves in the world’s oceans contain a renewable source of free power on the order of terawatts that has to this date not been commercially utilized. The division of Electricity at Uppsala University is developing a technology to harvest this energy. LÄS MER

  5. 24. Spatial and Temporal Variations of Solifluction and Related Environmental Parameters in the Abisko Mountains, Northern Sweden

    Författare :Hanna Ridefelt; Jan Boelhouwers; Antoni Lewkowicz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solifluction; movement rates; Abisko region; Geographical Information Systems; statistical modelling; geomorphic work; permafrost; Physical geography; Naturgeografi; naturgeografi; Physical Geography;

    Sammanfattning : This thesis presents an assessment of the variation in solifluction occurrence, morphometry and movement rates in the Abisko region, northern Sweden. Variations in movement rates are analyzed both on a regional and local scale. LÄS MER

  7. 25. Mechanisms and Phenomena in Braking and Gripping

    Författare :Lars Hammerström; Staffan Jacobson; XXX XXX; Uppsala universitet; []
    Nyckelord :Materials science; Friction; Brake; Texture; Squeal; Materialvetenskap;

    Sammanfattning : Applications relying on a high static friction include various types of fixtures, couplings, bolted joints, torsion joints, etc. The common characteristic of these applications is that they rely on the friction force to maintain the relative position of two mating surfaces.
