  1. 1. Bone and kidney effects from cadmium exposure : dose effect and dose response relationships

    Författare :Tobias Alfvén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bone; bone mineral density; cadmium; epidemiology; environmental exposure; fractures; heavy metals; human; kidneys; occupationally exposure; osteoporosis; protein HC; tubular proteinuria;

    Sammanfattning : Cadmium is a heavy metal that has been dispersed in the environment during the last century due to human activity. It is well known that high cadmium exposure causes renal damage and in severe cases also osteoporosis and osteomalacia. Osteoporosis is a major cause of morbidity worldwide. LÄS MER

  3. 2. Violence gratuite et adolescents-bourreaux : Réception, traduction et enjeux de deux romans suédois pour adolescents, en France, au début des années 2000

    Författare :Valérie Alfvén; Maria Walecka-Garbalinska; Boel Westin; Isabelle Chevrel; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Adolescent literature; censorship; France and Sweden; norms; Polysystem Theory; reception; role of the translator; sensitive topic; taboo; translation; unprovoked violence; Young adult literature; French; franska;

    Sammanfattning : The purpose of this thesis is to contribute to a better understanding of the role of Swedish literature for adolescents in the French literary scene in the early 2000s. The sociology of literature constitutes the main theoretical framework of this thesis. LÄS MER

  4. 3. Allergy, Stress and Sense of Coherence in Families with Children living in accordance with an Anthroposophic Lifestyle

    Författare :Jackie Swartz; Frank Lindblad; Thöres Theorell; Johan Alm; Gösta Alfvén; Uppsala universitet; []
    Nyckelord :Anthroposophic lifestyle; Allergy; Stress; Children; Sense of Coherence; Medicin; Medicine;

    Sammanfattning : Background: Previous studies on anthroposophic lifestyle and allergy show that the children have less risk of developing allergies. All studies so far have been retrospective and have included children in school age. LÄS MER

  5. 4. Runaway electrons and Alfvén eigenmodes in tokamaks

    Författare :Håkan Smith; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; two-way diffusion equation; compressional Alfvén eigenmode; fusion plasma physics; tokamak disruption; runaway electron; Alfvén cascade;

    Sammanfattning : Runaway electrons can be generated as a consequence of the rapid thermal quench of the plasma in a tokamak disruption. If the time scale of this cooling is short compared to the collision time in the tail of the electron velocity distribution, incomplete thermalisation of this tail leads to a burst of runaway production.

  7. 5. Alfvén Waves and Energy Transformation in Space Plasmas

    Författare :Yuri Khotyaintsev; Kalevi Mursula; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; Alfvén waves; particle acceleration; ionosphere; magnetopause; magnetic reconnection; Rymd- och plasmafysik; Space physics; Rymdfysik; Space Physics; rymdfysik;

    Sammanfattning : This thesis is focused on the role of Alfvén waves in the energy transformation and transport in the magnetosphere. Different aspects of Alfvén wave generation, propagation and dissipation are considered. The study involves analysis of experimental data from the Freja, Polar and Cluster spacecraft, as well as theoretical development. LÄS MER
