  1. 1. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis

    Författare :Marino Grozdek; Per Gunnar Lundqvist; Michael Kauffeld; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; cool thermal energy storage system; ice; modelling; simulation; field measurement; experiment; indirect system; ice-on-coil system; external melt; ice slurry; homogeneous storage; heterogeneous storage; Thermal energy engineering; Termisk energiteknik;

    Sammanfattning : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. LÄS MER

  3. 2. Glacier-Ocean Interactions in the Arctic : Contemporary calving and frontal melt from field observations, remote sensing, and numerical modelling

    Författare :Felicity Alice Holmes; Nina Kirchner; Benedict T. I. Reinardy; Riko Noormets; Jason Briner; Stockholms universitet; []

    Sammanfattning : Globally, glaciers are losing mass as a result of the changing climate, with this mass loss having a considerable societal impact through rising sea levels. Glaciers which terminate in the oceans are particularly vulnerable to changing external conditions as a result of high sensitivity at their marine margins. LÄS MER

  4. 3. Mechanical Behaviour of Adhesive Joints in Cartonboard for Packaging

    Författare :Christer Korin; Magnus Lestelius; Nils Hallbäck; Christophe Barbier; Christer Fellers; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot melt Adhesives; Carton board; Y-peel; Peel strength; Chemical Engineering; Kemiteknik;

    Sammanfattning : A cartonboard package is often sealed and closed with an adhesive – either a hot-melt adhesive (adhesives that are applied in a molten state on the cartonboard) or a dispersion adhesive (adhesives that are applied as water-based dispersions). This thesis focuses on the process of hot-melt gluing, and how material properties and process conditions affect the performance of the adhesive joint. LÄS MER

  5. 4. Phenomenological and mechanistic modeling of melt-structure-water interactions in a light water reactor (LWR) severe accident

    Författare :Anh Bui Viet; KTH; []
    Nyckelord :;

    Sammanfattning : Severe accidents in light water reactors have been the fotalpoint of much research, performed in the last two decades,aimed at understarrding the inherent physical phenomena and toevaluate proposed accident management schemes for mitigatingthe consequences of such accidents. Severe accident progressionand consequences, av the reactor core overheats and melts, areintimately related to the interactions of the melt with coolant(water) and structures. LÄS MER

  7. 5. Målsättning riksdagen : Ett aktörsperspektiv på nya partiers inträde i det nationella parlamentet

    Författare :Niklas Bolin; Svante Ersson; Jan Sundberg; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; new political parties; agency; strategies; Sweden; the Green Party; the Christian Democrats; the New Democracy Party; the Sweden Democrats; Political science; Statsvetenskap; statskunskap; political science;

    Sammanfattning : During much of the 20th century, the national party systems of Western Europe remained largely unchanged. However, beginning in the 1970s, these frozen party systems slowly started to melt. As the number of parties has increased, the question of what explains new party entrance has also attracted more scholarly interest. LÄS MER
