    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor Economics; Unemployment Insurance; Wage Level and Structure; Job Search; Duration Analysis; Econometric and Statistical Methods; Selection Models; Economics; Nationalekonomi;

    Sammanfattning : Essay I: Wage setting models typically posit a tight relationship between the generosity of unemployment insurance (UI) and equilibrium wages. This paper estimates the effect of UI on workers’ wages. LÄS MER

  3. 7. When the Rubber Meets the Road -Ecotoxicological Hazard and Risk Assessment of Tire Wear Particles

    Författare :Anna Wik; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tire wear; tire particles; rubber; leaching tests; ecotoxicity tests; Daphnia magna; Ceriodaphnia dubia; Pseudokirchneriella subcapitata; Danio rerio; toxicity identification evaluation; detention ponds; hazard assessment; risk assessment;

    Sammanfattning : Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this th.. LÄS MER

  4. 8. Earthquake Sources, the Stress Field and Seismic Hazard : A Study in Eritrea and its Surrounding

    Författare :Lijam Zemichael Hagos; Roland Roberts; Hossein Shomali; Kuvvet Atakan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Seismic hazard; Focal mechanism; Moment tensor inversion; Stress field; Afar depression; Eritrea; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : Presented in this thesis are some basic concepts and applications of seismic hazard analysis and the elements that influence the amplitude and geometric attenuation of earthquake ground motion. This thesis centers on the identification of the styles of failure, focal mechanisms, and the state of regional stress in the study area. LÄS MER

  5. 9. Ecotoxicological classification of ash materials

    Författare :Sara Stiernström; Magnus Breitholtz; Christina Rudén; David Bendz; Olof Berglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ecotoxicity; ash; classification; leaching; Waste Framework Directive; CLP-Regulation; Hazard Identification; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. LÄS MER

  7. 10. Ensuring the intended volume is given the intended absorbed dose in radiotherapy: Managing geometric variations and treatment hazards

    Författare :Ola Holmberg; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; tomography; radiology; Clinical physics; safety; risk; hazard; organ motion; set-up; margins; volume definition; radiotherapy; accuracy; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

    Sammanfattning : Methods for ensuring that the intended volume receives the intended absorbed dose in radiotherapy have been investigated. In order to optimise radiation treatment of cancer, geometric variations in the treatment chain need to be controlled. Furthermore, hazards potentially leading to unintended irradiation need to be controlled. LÄS MER
