  1. 21. Familjen i dalen : Tove Janssons muminvärld

    Författare :Boel Westin; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Mumintrollen fiktiva gestalter; Jansson; Tove; 1914-2001;

    Sammanfattning : Convincing children’s books are full of symbols, identification, self-obsession, Tove Jansson writes in an essay. My study of the construction of the Moomin world, the author’s way of writing and her creative methods aims to penetrate deeper into this universe and to discover its artistic potential. LÄS MER

  3. 22. Correlations in Finite Fermi Systems - Semiclassics and Shell Structure

    Författare :Henrik Uhrenholt; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2008:Uhrenholt;

    Sammanfattning : This dissertation investigates correlations in finite Fermi systems. The atomic nuclei is the mainly studied system but also other systems, like superconducting metallic grains and cold Fermionic gases are considered. The dissertation comprises of five original papers. LÄS MER

  4. 23. Using an Artificial Ecosystem to Understand Living Ecosystems

    Författare :Yu Liu; David Sumpter; Philip Gerlee; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Biology; Mathematical Modeling; Emergence; Ecosystem Evolution; Community Ecology; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Sammanfattning : Community ecosystems at very different levels of biological organization often have similar properties. Coexistence of multiple species, cross-feeding, biodiversity and fluctuating population dynamics are just a few of the properties that arise in a range of ecological settings. LÄS MER

  5. 24. An Experimental Study on Micro-Hydrodynamics of Evaporating/Boiling Liquid Film

    Författare :Shengjie Gong; Ma Weimin; Horst-Michael Prasser; KTH; []
    Nyckelord :liquid film; critical thickness; boiling; critical heat flux; rupture; dry spot; confocal optical sensor; SRA - Energy; SRA - Energi;

    Sammanfattning : Study of liquid film dynamics is of significant importance to the understanding and control of various industrial processes that involve spray cooling (condensation), heating (boiling), coating, cleaning and lubrication. For instance, the critical heat flux (CHF) of boiling heat transfer is one of the key parameters ensuring the efficiency and safety of nuclear power plants under both operational and accident conditions, which occurs as the liquid layers (microlayer and macrolayer) near the heater wall lose their integrity.

  7. 25. Arithmetic and Hyperbolic Structures in String Theory

    Författare :Daniel Persson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Instantons; Kac-Moody algebras; Spacelike singularities; String Theory;

    Sammanfattning : This thesis consists of an introductory text followed by two separate parts which may be read independently of each other. In Part I we analyze certain hyperbolic structures arising when studying gravity in the vicinity of spacelike singularities (the BKL-limit). LÄS MER
