  1. 1. Turbulent impurity transport in tokamaks

    Författare :Albert Mollén; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gyrokinetic; tokamak; impurity; poloidal asymmetry.; turbulence; transport; fusion plasma physics;

    Sammanfattning : Nuclear fusion is foreseen as one of the options for future energy production. One of the remaining scientific challenges for establishing the physics basis of future magnetic fusion reactors is to find scenarios where the impurity content in the core can be kept low. LÄS MER

  2. 2. Jesus and Purity Halakhah : Was Jesus Indifferent to Impurity?

    Författare :Thomas Kazen; James D. G. Dunn; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Religion; Bible; New Testament; Jesus; Judaism; Second Temple; purity; impurity; purification; ritual; halakhah; historical reconstruction; quest; authenticity; criteria; gospels; narrative traditions; redaction; law; Torah; conflict stories; Pharisees; expansionist current; miqveh; immersion; stone vessels; food; leper; leprosy; discharge; corpse; rabbinic texts; Tannaim; Dead Sea Scrolls; moral trajectory; John the Baptizer; diversity; am ha-arets; great tradition; little tradition; Galilee; demonology; exorcism; eschatology; kingdom.; Religionsvetenskap Teologi; Religion Theology; Religionsvetenskap Teologi; New Testament Exegesis; nya testamentets exegetik; Nya testamentets exegetik;

    Sammanfattning : At the end of the Second Temple period, ritual purity came to play an increasing role in Jewish society. Purity laws were interpreted and expanded, and sources of impurity were generally avoided by many. LÄS MER

  3. 3. Impurity transport in magnetically confined fusion plasmas

    Författare :Albert Mollén; Chalmers University of Technology; []
    Nyckelord :fusion plasma physics; transport; turbulence; tokamak; gyrokinetic; impurity; stellarator; drift-kinetic; poloidal asymmetry;

    Sammanfattning : Nuclear fusion is foreseen as one of the options for future energy production. In establishing the physics basis of future magnetic fusion reactors it is necessary to find scenarios where the impurity content in the core can be kept low. LÄS MER

  4. 4. Turbulent impurity transport in tokamak fusion plasmas

    Författare :Andreas Skyman; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tokamaks; fluid theory; ion temperature gradient mode; impurity transport; trapped electron mode; fusion plasma physics; turbulence; e-science; Joint European Torus; gyrokinetic theory;

    Sammanfattning : With the enormous growth of high performance computing (HPC) over the last few decades, plasma physicists have gained access to a valuable instrument for investigating turbulent plasma behaviour. In this thesis, these tools are utilised for the study of particle transport in fusion devices of the tokamak variety, focusing in particular on the transport of impurities. LÄS MER

  5. 5. Fluctuations in Mesoscopic Constrictions

    Författare :Jan Peter Hessling; Chalmers University of Technology; []
    Nyckelord :low frequency; fluctuations; quantum; noise; 1 f-noise; superconductivity; impurity; point contact; Andreev reflection; shot noise;

    Sammanfattning : In normal and superconducting quantum point contacts there are several sources of fluctuations. Thermally activated impurities in the vicinity of the junction cause the current (or voltage) to change with a typical frequency of the order of one Hz up to a few kHz. LÄS MER
