  1. 1. Particulate Debris Spreading and Coolability

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Simone Basso; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-leveling; debris bed; spreading; coolability; severe accident; probabilistic framework; Monte Carlo; uncertainty; sensitivity; Fysik; Physics;

    Sammanfattning : In Nordic design of boiling water reactors, a deep water pool under the reactor vessel is employed for the core melt fragmentation and the long term cooling of decay heated corium debris in case of a severe accident. To assess the effectiveness of such accident management strategy the Risk-Oriented Accident Analysis Methodology has been proposed. LÄS MER

  3. 3. Dynamic Wetting of Solid Surfaces, Influence of Surface Structures and Surface Active Polymers

    Detta är en avhandling från Institute for Surface Chemistry, Box 5607, SE-114 86 Stockholm

    Författare :Stina Gerdes; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; stick-slip; Wilhelmy plate; block copolymers; surface active polymers; surface channels; spreading; contact angles; dynamic wetting; surface structures; Fysikalisk kemi;

    Sammanfattning : The effect of surface structures on the dynamics of wetting was investigated through measurements of the dynamic contact angle and spreading velocity of oil droplets spreading over surfaces with parallel and gridlike V-shaped channels. A rim of liquid was observed to spread out in the channels ahead of the dropfront after a short time of spreading (seconds). LÄS MER

  4. 4. Wetting and Capillary Flow of Surfactant Solutions and Inks

    Detta är en avhandling från Britt Nyström, YKI Ytkemiska Institutet AB, Box 5607, SE-114 86 Stockholm, Sweden, [email protected]

    Författare :Maria von Bahr; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; AKD; ink-jet printing; paper; penetration; absorption; adsorption; hydrophobicity; nonionic; surfactant; spreading; dynamic wetting;

    Sammanfattning : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. LÄS MER

  5. 5. Integrin Signaling in Cell Adhesion and Mechanotransduction Regulation of PI3K, AKT, and ROS

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Kathrin Stephanie Zeller; Uppsala universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; integrin; ROS; PI3K; AKT; mechanosignaling; actin polymerization; spreading;

    Sammanfattning : Integrins are a family of conserved cell surface receptors found throughout the animal kingdom. They comprise 24 dimers in mammals, and regulate a number of processes including cell survival, differentiation, and migration. LÄS MER
