  1. 1. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems

    University dissertation from Johan Reimer, Chemical Centre, Lund University

    Author : Johan Reimer; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; micellar network; NMR diffusometry; microemulsion; microstructure; phase diagram; phase separation; phase behaviour; alkyl glucoside; sugar surfactant;

    Abstract : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. READ MORE

  2. 2. Transition in Particle-laden Flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Joy Klinkenberg; Luca Brandt; Shuisheng He; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; multi-phase flow; particle-laden; heavy particles; light particles;

    Abstract : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. READ MORE

  3. 3. Phase Transitions in Large Oscillator Lattices

    University dissertation from Norbergsgatan 5A, 223 54 Lund

    Author : Per Östborn; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; phase transition; limit cycle oscillator; frequency entrainment; synchronization; sinus node; classical mechanics; Mathematical and general theoretical physics; arrhythmia; gravitation; quantum mechanics; relativity; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Östborn;

    Abstract : This thesis deals with large networks of limit cycle oscillators. A limit cycle oscillator is a dynamical system that has a periodic attractor in phase space, and is defined in continuous time. To each such oscillator one can associate a natural frequency. READ MORE

  4. 4. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

    University dissertation from Physical Chemistry 1, Lund University

    Author : Anna Karin Morén; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phase equilibria; Protein-surfactant interactions; Gel; Precipitate; Solution; Lysozyme; b-lactoglobulin; Ovalbumin; Bovine serum albumin; Dodecyltrimethylammonium chloride; Sodium alkylsulphates; NMR; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

    Abstract : Protein-surfactant interactions in water are investigated by following the phase equilibria for protein-surfactant pairs whose constituents carry both opposite and the same sign of charge. The concentration ranges studied are: 0-20 wt% protein, 0-20 wt% surfactant, and 80-100 wt% water. READ MORE

  5. 5. Transcription regulation and growth phase transition in hyperthermoacidophilic archaea

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University
