  4. 7. Consequences of Poor Housing : Essays on Urban and Health Economics

    Author : Fredrik Hansson; Matz Dahlberg; Che-Yuan Liang; Aline Bütikofer; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban; health; education; in utero; pollution; radiation; uranium; radon; housing prices; happiness; well-being; urbanization; growth; Economics; Nationalekonomi;

    Abstract : Essay I: Research shows that low fetal doses of radiation from nuclear catastrophes and atmospheric test bombings of nuclear weapons cause cognitive birth defects. These events are uncommon and the radioactive isotopes they create rarely reach harmful levels in nature. READ MORE

  5. 8. Re-interventions after endovascular aortic repair: clinical and experimental studies

    Author : Håkan Roos; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EVAR; stent graft; blood flow; displacement forces; aortic aneurysm; angulation; reoperation;

    Abstract : Background: Endovascular aortic repair (EVAR) has lower morbidity and mortality than open surgery. Late complications and re-interventions are more common, however, and the timing of different re-interventions and their respective underlying causes are not fully understood. READ MORE

  6. 9. Deracemization of Functionalized Alcohols via Combined Ruthenium and Enzyme Catalysis

    Author : Ann-Britt L. Fransson; Jan-Erling Bäckvall; Hans-Erik Högberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Abstract : The major part of this thesis describes the synthesis of enantiopure alcohols and diols by combining ruthenium-catalyzed racemization or epimerization and lipase-catalyzed asymmetric transformations. A minor part of this thesis is focused on ruthenium-catalyzed redox reactions for transfer hydrogenation of 1,3-cycloalkanediketones. READ MORE

  7. 10. DNA Electrophoresis: Optical Probing and Microscopic Imaging to Understand Separation Mechanisms

    Author : Anette Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical probing; YOYO; polarized light spectroscopy; DNA electrophoresis; DAPI; binding modes; helix alignment; fluorescence microscopy;

    Abstract : The aim of this work was to combine spectroscopic, mobility, and fluorescence microscopy studies to elucidate the mechanisms behind DNA electrophoresis, a method to separate DNA molecules according to size. The microscopy studies require staining of the DNA with a fluorescent dye. READ MORE
