1. 16. The Dynamical Spin Vector Evolution of the Asteroids

   Författare :Erik Skoglöv; Karri Muinonen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; asteroids; Eros; Ceres; Vesta; dynamics; rotation; rotational dynamics; orbits; resonances; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; astronomi; Astronomy;

   Sammanfattning : The dynamical evolution of the spin axis direction due to gravitational and thermal factors is examined. It is found that the spin axis variations generally are regular and relatively small for the bodies in the asteroid main belt. There are also reasons to believe that this is the case for minor objects beyond the main belt. LÄS MER

3. 17. Procedure for the reduction of the effect of transient whole body vibrations

   Författare :Peter Jönsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Sammanfattning : There is a growing interest in the topic areas of increased vibration comfort and reduced vibration levels in work vehicles. Legislation, health costs and demands for increased competitiveness are all important motivating factors in this growing interest. LÄS MER

4. 18. Disclosing the Books : Evidence on Swedish publicly listed firms' accounting disclosure practices

   Författare :Derya Vural; Mattias Hamberg; Nils-Göran Olve; Thomas Plenborg; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; disclosure; disclosure index; agency theory; ownership structure; control-enhancing mechanisms; capital-market effects; Business Studies; Företagsekonomi;

   Sammanfattning : Disclosure of accounting information is crucial in facilitating efficient contracts in the publicly listed firm and in reducing information asymmetries in capital markets. A well-known perception in disclosure literature is that, as the separation between managers and owners increases, so does the demand for publicly available disclosure. LÄS MER

5. 19. Outcome of Stroke Prevention : Analyses Based on Data from Riks-Stroke and Other Swedish National Registers

   Författare :Signild Åsberg; Andreas Terént; Hélène Pessah; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; Epidemiology; Age groups; Risk factors; Atrial fibrillation; Secondary prevention; Anticoagulants; Antiplatelets; Hemorrhage; Mortality.; Medicinsk vetenskap; Medical Science;

   Sammanfattning : The aim of this thesis was to explore variations in stroke prevention and the effect of prevention on outcome. The studies were based on patients registered in the Swedish Stroke Register between 2001 and 2009 and although used to different extents in each paper, additional information was retrieved through linkage to The National Patient Register, the Cause of Death Register, the Prescribed Drug Register and the Total Population Register.

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bathymetry mapping; model verification; water balance; correlation; tracer transport; wind hydrodynamics; pollution and nutrient transport; climate effect; Mark- och vattenteknik; Land and Water Resources Engineering;

   Sammanfattning : A very small part of the total earth’s water is freshwater (only 2.5 %). Unfortunately, due to climate change and pervasive manmade activities, surface freshwater quality in many places of the world has become degraded. LÄS MER
