  3. 7. Zero-Field Splitting in Gd(III) complexes : Towards a molecular understanding of paramagnetic relaxation

    Författare :Shehryar Khan; Michael Odelius; Arnold Maliniak; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zero-Field Splitting; Relaxation; Quantum Chemistry; Molecular Dynamics; Gd III ; kemisk fysik; Chemical Physics;

    Sammanfattning : The prime objectives of contrast agents in Magnetic Resonance Imaging(MRI) is to accelerate the relaxation rate of the solvent water protons in the surrounding tissue. Paramagnetic relaxation originates from dipole-dipole interactions between the nuclear spins and the fluctuating magnetic field induced by unpaired electrons. LÄS MER

  4. 8. Ethical Issues in the Adoption and Implementation of Vision Zero Policies in Road Safety

    Författare :Henok Girma Abebe; Karin Edvardsson Björnberg; Sven Ove Hansson; Matts-Åke Belin; Elin Palm; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Ethics; Equity; Road Safety; Vision Zero; Responsibility; Systems Thinking; Risk; Drivin; Philosophy; Filosofi;

    Sammanfattning : The aim of this doctoral thesis is to analyze ethical issues in the adoption and implementation of Vision Zero policies. The first article analyses criticisms against Vision Zero goals and measures promoted to reach them. We identify and assess “moral”, “operational”, and “rationality-based” arguments against Vision Zero. LÄS MER

  5. 9. On Zero-dimensional Modelling of Combustion and NOx Formation in Diesel Engines

    Författare :Rolf Egnell; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; Motors and propulsion systems; NOx Formation; Zero-Dimensional; Modelling; Diesel Engines; Termisk teknik; Thermal engineering; applied thermodynamics; termodynamik;

    Sammanfattning : Diesel engine developers are facing major challenges when meeting future demands on NOx and particulate emissions. The exhausts after treatment systems are rapidly improving and the technologies available in a few years will be capable of cutting emission levels close to the demanded levels. LÄS MER

  7. 10. The Rationality and Moral Acceptability of Vision Zero Goal and Its Interventions

    Författare :Henok Girma Abebe; Karin Edvardsson Björnberg; Sven Ove Hansson; Matts-Åke Belin; Jessica Nihlén Fahlquist; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Ethics; Road Safety; Vision Zero; Responsibility; Goal setting; Filosofi; Philosophy;

    Sammanfattning : This licentiate thesis discusses moral issues associated with road safety work, with a particular emphasis on the Vision Zero (VZ) goal and its interventions. The licentiate thesis contains three articles and an introduction that briefly discusses issues and arguments presented in the articles. LÄS MER
