  2. 1. Modelling Ion Cyclotron Resonance Heating and Fast Wave Current Drive in Tokamaks

    Author : Abdul Hannan; Torbjörn Hellsten; Dirk van Eester; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermonuclear fusion; Tokamak; DIII-D; JET; ITER; DEMO; ICRF; ICRH; Fast magnetosonic waves; TTMP; ELD; ICRH; Thermonuclear;

    Abstract : Fast magnetosonic waves in the ion cyclotron range of frequencies have the potential to heat plasma and drive current in a thermonuclear fusion reactor. A code, SELFO-light, has been developed to study the physics of ion cyclotron resonantheating and current drive in thermonuclear fusion reactors. READ MORE

  4. 2. Effects of Inflammatory Mediators on Pulmonary Airways

    Author : Ofir Bachar; Klinisk och experimentell allergiforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electric ?eld stimulation; bradykinin; airway; tumor necrosis factor a; Respiratory system; nitric oxide; Andningsorganen; Toll-like receptor; prostaglandin E2; neurotrophin; allergy;

    Abstract : Chronic inflammation is together with excessive contraction of the airways key features of asthma. The aims of the thesis were to analyze the effect of inflammatory mediators on airway smooth muscle, using an in vitro model of cultured murine airways. READ MORE

  5. 3. Feedback control of resistive wall modes in the reversed field pinch

    Author : Dimitry Yadikin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Reversed eld pinch; current driven modes; thin resistive wall; resistive wall; Fysik; Physics; Fysik;

    Abstract : A wide range of unstable current driven MHD modes is present in the re- versed τeld pinch (RFP) conτguration. An ideally conducting wall facing the plasma can stabilize the ideal MHD modes. READ MORE

  6. 4. Electron dynamics in graphene in the presence of an electrical field

    Author : Roland Jago; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bloch equations; density matrix formalism; graphene; relaxation dynamics; photoconduction effect; carrier multiplication;

    Abstract : Graphene as atomically thin two-dimensional material exhibits remarkableoptical and electronic properties that suggest its technological applicationin novel optoelectronic devices, such as graphene-based lasers and photodetectors.The linear electronic bandstructure and the vanishing band gap atthe Dirac point open up new relaxation channels, such as Auger scattering.

  7. 5. The Prometheus Complex : Striving for competence

    Author : Renée Perrin-Wallqvist; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Childhood; Fire setting; Adolescence; Psychology; Development psychology; Psykologi; Utvecklingspsykologi; Psykologi;

    Abstract : The purpose of the present investigations was to obtain a more comprehensive view of fire setting by children and adolescents; to explore the prevalence of the phenomenon; whether or not it experimentally may be related to frustration or boredom and to examine the role of personality traits such as optimism, pessimism and creativity. This dissertation consists of two experimental and two interview studies. READ MORE
