  1. 16. Improving alternatives assessment of plastic additives : exploring in silico tools to identify less hazardous flame retardants

    Författare :Ziye Zheng; Patrik L. Andersson; Hans Peter Arp; Gregory Peters; Gerrit Schüürmann; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical alternatives assessment; plastic additives; flame retardants; hazard; emission; in silico; modeling; quantitative structure-activity relationship QSAR ; multi-criteria decision analysis MCDA ; environmental science; miljövetenskap; organisk kemi; Organic Chemistry; ekotoxikologi; Ecotoxicology; Toxicology; toxikologi;

    Sammanfattning : Alternatives assessment is applied for replacing hazardous chemicals with viable, safer substitutes. High quality experimental hazard data, however, are usually unavailable for this purpose, and obtaining in silico data is the only approach to fill in data gaps. LÄS MER

  3. 17. 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

  4. 18. Prediction of Strong Ground Motion and Hazard Uncertainties

    Författare :Behrooz Tavakoli; Ota Kulhanek; Dieter Mayer-Rosa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Disaggregation; Ground motion; Monte Carlo simulation; Seismic hazard; Geofysik; Geophysics; Geofysik; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : The purpose of this thesis is to provide a detailed description of recent methods and scientific basis for characterizing earthquake sources within a certain region with distinct tectonic environments. The focus will be on those characteristics that are most significant to the ground-shaking hazard and on how we can incorporate our current knowledge into hazard analyses for engineering design purposes.

  5. 19. Moral Hazard and Insurance: Optimality, Risk and Preferences

    Författare :Kristian Sundström; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; asymmetric information; second best solution; first best solution; Insurance; Moral Hazard;

    Sammanfattning : The thesis consists of an introductory chapter, followed by three chapters which all deal with theoretical issues related to moral hazard and insurance. In Chapter 2 we assume symmetric and perfect information. LÄS MER

  7. 20. The Analysis of Duration and Panel Data in Economics

    Författare :Wolfgang Hess; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Monetary Exchange Rate Model; Homogeneity Testing; Panel Cointegration; Pooling; Duration of Trade; Unemployment Duration; Proportional Hazards; Unobserved Heterogeneity; Hazard Rate; Discrete-Time Duration Model; Threshold Excess Model;

    Sammanfattning : This thesis is divided into two distinct parts. The first part contains three chapters dealing with the analysis of duration data from an econometric perspective and with application to trade durations. LÄS MER
