1. 1. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

   Författare :Kristofer Bodvard; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

   Sammanfattning : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. LÄS MER

3. 2. Energy and intensity modulated radiation therapy with electrons

   Författare :Lennart Olofsson; Mikael Karlsson; Magnus Karlsson; Björn Zackrisson; Erik Traneus; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Radiation therapy; Conformal therapy; IMRT; Electrons; Electron treatment head; Electron MLC; Bremsstrahlung reduction; Integral dose; Penumbra; Output factor; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiofysik; radiation physics;

   Sammanfattning : In recent years intensity modulated radiation therapy with photons (xIMRT) has gained attention due to its ability to reduce the dose in the tissues close to the tumour volume. However, this technique also results in a large low dose volume. LÄS MER

4. 3. Tissue Factor in Transplantation -aspects on expression and inhibition

   Författare :Cecilia Österholm; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nephrotoxicity; tissue factor; transplantation; ischemia-reperfusion injury; serologi; Immunologi; serology; Immunology; extracellulära vätskor; Hematologi; extracellular fluids; traumatology; Kirurgi; Urology; nephrology; Urologi; nefrologi; Surgery; orthopaedics; ortopedi; traumatologi; Haematology; chronic rejection;

   Sammanfattning : Organ transplantation provides a treatment of end-stage disease primarily in the kidney, liver and heart. The immunosuppressive treatment regimens of today efficiently prevent early acute rejection; however the long-term survival has not improved to the same extent. LÄS MER

5. 4. Intra-industry trade: measurements, determinants and growth : a study of Swedish foreign trade

   Författare :Pär Hansson; Lars Lundberg; David Greenaway; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intra-industry trade; determinants; comparative costs; factor intensity; product differentiation; elasticity of substitution; economies of scale; quasi-homothetictastes; Sweden; Economics; Nationalekonomi;

   Sammanfattning : The conclusions are that a traditional factor proportions model seems neither theoretically nor empirically to explaing IIT. However, a relaxation of the assumption of homogeneous products in an industry gives rise to several implications for IIT. LÄS MER

7. 5. Economic growth, energy consumption and CO2 emissions in Sweden 1800-2000

   Författare :Astrid Kander; Ekonomisk-historiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy intensity; Environmental Kuznets Curve; relative price analyses; standard calculations; technical change; structural changes; energy quality factors; consumers surplus; Social and economic history; forest management; CO2 intensity; Ekonomisk och social historia;

   Sammanfattning : Large transformations of technologies have occurred in the Swedish economy during the last two centuries, resulting in higher income, better quality of products and changing composition of GDP. An agrarian society has given way to an industrial society and lately to a post-industrial phase. LÄS MER
