  1. 1. Mechanistic-Empirical Modeling of Permanent Deformation in Asphalt Concrete Layers

    University dissertation from Department of Technology and Society, Lund University

    Author : Erik Oscarsson; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; modeling; Mechanistic-Empirical; rutting; asphalt concrete; full-scale pavements;

    Abstract : Three mechanistic-empirical permanent deformation models were evaluated under Swedish conditions with respect to traffic, climate and materials using accelerated pavement testing and long-term pavement performance studies. The mechanistic-empirical pavement design guide (M E PDG), the incremental-recursive mechanistic-empirical CalME model (CalME), and the PErmanent Deformation of asphalt concrete layer for ROads (PEDRO) model generally showed both useful features and limitations.

  2. 2. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide

    University dissertation from Lunds universitet, instutionen för teknik och samhälle, trafik och väg

    Author : Erik Oscarsson; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; design guide; asphalt concrete; mechanistic empirical;

    Abstract : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. READ MORE

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Oscarsson; Håkan Rensmo; Erik Johansson; Anders Hagfeldt; Gunnar Öhrwall; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cell; DSC; mesoscopic solar cell; photoelectron spectroscopy; PES; XPS; interface; TiO2; NiO; co-adsorption; co-adsorbent; collaborative sensitization; mixed molecular layers; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The increasing demand for renewable energy has led to substantial research on different solar cell technologies. The dye-sensitized solar cell (DSC) is a technology utilizing dye molecules for light absorption. READ MORE

  4. 4. Perioperative myocardial damage and cardiac outcome in patients-at-risk undergoing non-cardiac surgery

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Anna Oscarsson Tibblin; Christina Eintrei; Sven-Erik Ricksten; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myocardial damage; cardiac complication; outcome; aspirin; acetylsalicylic acid; MEDICINE Surgery Anaesthetics and intensive care; MEDICIN Kirurgi Anestesiologi och intensivvård;

    Abstract : Despite increasingly sophisticated perioperative management, cardiovascular complications continue to be major challenges for the clinician. As a growing number of elderly patients with known coronary artery disease (CAD) or with risk factors for CAD are undergoing non-cardiac surgery, cardiovascular complications will remain a significant clinical problem in the future.

  5. 5. Studies on regulatory networks governing virulence gene transcription in Staphylococcus aureus

    University dissertation from Karolinska Institutet

    Author : Erik Gustafsson; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural sciences;

    Abstract : Staphylococcus aureus pathogenicity is dependent on the coordinated action of a number of virulence factors and the expression of these virulence factors is determined by several global regulators. The main regulator seems to be agr but there are several additional regulators (mostly sarA homologues) involved that mainly act downstream of agr. READ MORE
