1. 1. Interaction between Electromagnetic Waves and Localized Plasma Oscillations

   Författare :Jan-Ove Hall; Thomas Leyser; Jan Trulsen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; space physics; plasma physics; radio waves; ionospheric modification; density depleations; field-aligned irregularities; lower hybrid solitary structures; lower hybrid cavities; Z mode waves; magnetosonic waves; scattering; mode conversion; Rymd- och plasmafysik; Space physics; Rymdfysik;

   Sammanfattning : This thesis treats interaction between electromagnetic waves and localized plasma oscillations. Two specific physical systems are considered, namely artificially excited magnetic field-aligned irregularities (striations) and naturally excited lower hybrid solitary structures (LHSS). LÄS MER

3. 2. Understanding the provision and processing of information for information-intensive products as a basis for market segmentation

   Författare :Daniel Edward Hall; Terrence Brown; Leyland Pitt; Jan Kietzmann; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information-intensive products; consumer information search; consumer information processing; marketing strategy; wine marketing; Industriell ekonomi och organisation; Industrial Engineering and Management;

   Sammanfattning : This thesis helps to address the gap in literature relating to the study of the provision of information to consumers, consumer information search behaviour and consumer information processing and choice behaviour relating to information-intensive products. Throughout the thesis, wine is taken as an example of an information-intensive product. LÄS MER

4. 3. Long-term outcome research on PDR brachytherapy with focus on breast, base of tongue and lip cancer

   Författare :Bengt Johansson; Jan Persliden; Jan Nyman; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDR; brachytherapy; outcome; partial breast irradiation; base of tongue cancer; lip cancer; quality of life; dosimetry.; Oncology; Onkologi; Surgery; Kirurgi; Onkologi; Oncology; Surgery; Kirurgi;

   Sammanfattning : Brachytherapy (BT) with continuous low dose rate (LDR) has been used for 100 years and is considered as the radiotherapy method able to deliver a dose in the shortest time with high efficacy and low risk of side effects. The drawbacks are need for patient isolation and radiation exposure of the staff during the treatment. LÄS MER

5. 4. Narratives and Bilateral Relations : Rethinking the "History Issue" in Sino-Japanese Relations

   Författare :Karl Gustafsson; Jan Hallenberg; Marie Söderberg; Linus Hagström; Martin Hall; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bilateral relations; Sino-Japanese relations; China; Japan; “history issue”; narrative; identity; Critical Discourse Analysis; Bilaterala relationer; sino-japanska relationer; Japan; Kina; narrativ; identitet; kritisk diskursanalys; Political science; Statsvetenskap; Political Science; statsvetenskap;

   Sammanfattning : The overarching aim of the thesis is to present a framework that makes possible an understanding of bilateral relations that challenges mainstream International Relations (IR) approaches through a study of the “history issue” in Sino-Japanese relations. A secondary aim is to provide an alternative understanding of this issue. LÄS MER

7. 5. Quasiparticles in the Quantum Hall Effect

   Författare :Janik Kailasvuori; Thors Hans Hansson; Jan Myrheim; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum Hall effect; quasiparticles; noncommutative Chern-Simons theory; nonabelian statistics; thin torus; p-wave superconductivity; topology; index theory; effective gauge fields; Condensed matter physics; Kondenserade materiens fysik;

   Sammanfattning : The fractional quantum Hall effect (FQHE), discovered in 1982 in a two-dimensional electron system, has generated a wealth of successful theory and new concepts in condensed matter physics, but is still not fully understood. The possibility of having nonabelian quasiparticle statistics has recently attracted attention on purely theoretical grounds but also because of its potential applications in topologically protected quantum computing.
