  1. 21. The dynamics of Alfvén eigenmodes excited by energetic ions in toroidal plasmas

    Författare :Emmi Tholerus; Torbjörn Hellsten; Thomas Johnson; Lars-Göran Eriksson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion plasma physics; tokamak; wave-particle interactions; toroidal Alfvén eigenmodes; bump-on-tail instabilities; magnetohydrodynamics; nonlinear dynamics; quasilinear dynamics; Hamiltonian mechanics; Monte Carlo method; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Experiments for the development of fusion power that are based on magnetic confinement deal with plasmas that inevitably contain energetic (non-thermal) particles. These particles come e.g. from fusion reactions or from external heating of the plasma. LÄS MER

  3. 22. Distribution and activity of pelagic fish - acoustic studies in the Baltic Sea

    Författare :Tomas Didrikas; Sture Hansson; Thomas Mehner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pelagic; fish; hydroacoustic; distribution; activity; Baltic; Biology; Biologi;

    Sammanfattning : Fisheries agencies around the Baltic Sea use hydroacoustics to assess stock sizes of herring and sprat. These assessments rely on the assumption that the acoustic properties of Baltic clupeids are the same as North Sea herring. LÄS MER

  4. 23. The dynamics of Alfvén eigenmodes excited by energetic ions in toroidal plasmas

    Författare :Emmi Tholerus; Thomas Johnson; Torbjörn Hellsten; Duarte Borba; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion plasma physics; Tokamak; Wave–particle interactions; Toroidal Alfvén eigenmodes; Bump-on-tail instabilities; Magnetohydrodynamics; Nonlinear dynamics; Quasilinear dynamics; Hamiltonian mechanics; Monte Carlo method; ICRH; FWCD; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The future fusion power plants that are based on magnetic confinement will deal with plasmas that inevitably contain energetic (non-thermal) particles. These particles come, for instance, from fusion reactions or from external heating of the plasma. LÄS MER

  5. 24. Bloom dynamics and population genetics of marine phytoplankton - Community, species and population aspects

    Författare :Karolina Härnström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; dynamics; Skeletonema marinoi; population genetics; resting stages;

    Sammanfattning : Phytoplankton are the most important primary producers in the world’s oceans and coastal waters, accounting for nearly half of the global net primary production. Although they are such important organisms, little is known about the ecology and dynamics of phytoplankton. LÄS MER

  7. 25. The Role of Suppliers and Resellers : Cases of Timber Product Distribution Channels

    Författare :Wei Guan; Jakob Rehme; Staffan Brege; Tomas Nord; Anders Roos; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Distribution channels; roles; role changes; downstream vertical integration; offerings; timber products;

    Sammanfattning : This dissertation aims to explain the impacts of distribution channel developments on the roles of timber product distribution channel actors. The role of channel actors in this dissertation is defined as the structured behaviour pattern that combines activities and resources in distribution channels. LÄS MER
