  1. 11. Laser Diagnostics in Combustion - Elastic Scattering and Picosecond Laser-Induced Fluorescence

    Författare :Frederik Ossler; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spray; Picosecond laser; Streak camera; Time resolved; Fluorescence lifetimes; 3 – D flow imaging; 2 - D lifetime imaging; Pressure; Temperature; Hydrogen atoms; Oxygen atoms; 3-pentanone; Acetone; Lorenz-Mie theory; Aerosol; Fysicumarkivet A:1999:Ossler; Scattering; Fysik; Physics; Polycyclic aromatic hydrocarbons.;

    Sammanfattning : Elastic scattering and the Lorenz-Mie (LM) theory in particular is used for the characterization of sub-micron- and micron-sized droplets of organic fuels in sprays and aerosols. Calculations on the Lorenz- Mie theory show that backward-sideward scattered visible radiation can be used for unambiguous detection of ensembles of homogeneous droplets of organic substances with diameters around 1 micrometer (size parameter between 2 and 6).

  3. 12. 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.

  4. 13. Dynamic Analysis and Modeling of Machine Tool Parts

    Författare :Tatiana Smirnova; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Boring bar vibration during internal turning operations in machine tools is a pronounced problem in the manufacturing industry. Vibration may easily be induced by the workpiece’s material deformation process, due to the bar’s normally slender geometry. LÄS MER

  5. 14. Analysis of human epidermal Langerhans' cells and allergens with confocal laser scanning microscopy

    Författare :Axel Emilson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :3-D analysis; allergen; allergic contact dermatitis; basal cellcarcinoma; Bet v I; birch; confocal laser scanning microscopy; epidermis; HLA-DR; image analysis; invariant chain; irritant contact dermatitis; Langerhans cell; occlusion; P. orbiculare;

    Sammanfattning : The aim of the thesis was to explore confocal laser scanning microscopy (CLSM) as a tool for 1) quantitative and 3-dimensional (3-D) analysis of the human antigen-presenting Langerhans' cell (LC) in epidermis and 2) for localization of allergens in yeast cells and in birch pollen. Epidermal LCs were investigated after occlusion with patch tests and in basal cell carcinoma (BCC) skin. LÄS MER
