  1. 11. Capillary electroseparations in pharmaceutical analysis of basic drugs and related substances

    Författare :Anna Maria Enlund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : Capillary electroseparation methods are exciting new techniques with very broad application areas and vast potential in pharmaceutical and biomedical analysis. To improve the limit of detection (LOD) capillary zone electrophoresis (CZE) has been combined with isotachophoretic (ITP) preconcentration in a single capillary. LÄS MER

  3. 12. Ground Improvement by Dry Deep Mixing Lime-Cement Column Panels as Excavation Support

    Författare :Razvan Ignat; Stefan Larsson; Sadek Baker; Sven Liedberg; Masaki Kitazume; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Many urban areas near the coastal regions of Sweden are characterized by post-glacial clay deposits with very low undrained shear strength and high compressibility. Column type ground improvement by the Deep Mixing, DM, method using a binder mixture of lime and cement is commonly used in areas with poor soil conditions due to its cost-effectiveness, predominantly for settlement reduction and to improve the stability of embankments.

    Sammanfattning : This thesis addresses assembly issues encountered in optical and fluidic microsystem applications. In optics, the first subject concerns the active alignment of components in optical fibersystems. LÄS MER

  7. 15. Analysis methodology for RBMK-1500 core safety and investigations on corium coolabiblty during a LWR sever accidnet

    Författare :Audrius Jasiulevicius; KTH; []
    Nyckelord :RBMK. Light water reactor. Core analysis; transient analysis; reactor dynamics;

    Sammanfattning : This thesis presents the work involving two broad aspectswithin the field of nuclear reactor analysis and safety. Theseare: - development of a fully independent reactor dynamics andsafety analysis methodology of the RBMK-1500 core transientaccidents and - experiments on the enhancement of coolabilityof a particulate bed or a melt pool due to heat removal throughthe control rod guide tubes.
