  4. 28. Synthesis of estradiol mimetics and potential anti-Alzheimer’s agents

    Författare :Erik Flöistrup; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis is composed of two projects, both involving synthesis aimed at drug discovery. The first project covers method development for the synthesis of substances that can be used in estrogen replacement therapy. LÄS MER

  5. 29. Probabilistic time estimation in tunnel projects

    Författare :Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Larsson Stefan; Anna Kadefors; Lars-Olof Dahlström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost overrun; Tunneling projects; Probabilistic approaches; time estimation; Kostnadsöverskridande; tunnelprojekt; sannolikhetsmetoder; tidsuppskattning; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Transport infrastructure projects, including tunneling, suffer from timedelays and cost overrun. A literature review shows that the effect ofuncertainty has been neglected in explaining time and cost overrunmeaning that technical explanations matter. LÄS MER

  7. 30. Analytical and numerical approaches to estimate peak shear strength of rock joints

    Författare :Francisco Ríos Bayona; Stefan Larsson; Fredrik Johansson; Diego Mas Ivars; José Muralha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock joint; Shear strength; Failure criterion; Numerical shear tests; Bergsprickor; Skjuvhållfasthet; Brottkriterium; Numeriska skjuvförsök; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : In Sweden, there exists a large number of dams. Many of them are founded on rock masses normally affected by the presence of sub-horizontal rock fractures, which makes sliding along rock joints under the dam foundation one of the most critical failure mechanism. LÄS MER
