  2. 1. Modification of flavonoid content and photosynthesis by ultraviolet-B radiation. Atrazine-tolerant and -sensitive ultivars of Brassica napus

    Author : Louise Olsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; recovery; quercetin; photosynthesis; photoinhibition; photoacoustics; leaf anatomy; kaempferol; flavonoid; D1 protein; fluorescence; cold stress; carbon dioxide; atrazine tolerance; Brassica napus; UV-B; Physiological biophysics; Växtfysiologi;

    Abstract : Levels of ultraviolet-B (UV-B, 280-320 nm) radiation reaching the Earth´s surface increase due to stratospheric ozone depletion. In this thesis the effect of enhanced UV-B radiation was studied on the atrazine-tolerant mutant Stallion, susceptible to photoinhibition, and the atrazine-sensitive cultivar Paroll of Brassica napus (oilseed rape).

  4. 2. Early detection of colorectal cancer

    Author : Louise Olsson; Örebro universitet; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Audit; colorectal cancer; diagnosis; faecal DNA; family history; population-based; survival; symptom duration.;

    Abstract : This thesis addresses the early detection of colorectal cancer from several aspects. An audit of the diagnostic process was conducted in 227/235 (97%) patients with recentlydiagnosed colorectal cancer in the County of Västmanland, Sweden in 1998-99. READ MORE

  5. 3. Equal Peace : United Nations Peace Operations and the Power-Relations between men and women in Timor-Leste

    Author : Louise Olsson; Peter Wallensteen; Mats Hammarström; Fen Osler Hampson; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; United Nations; Peacekeeping; Peace Operations; Peacebuilding; Equality; Timor-Leste; Peace and conflict research; Freds- och konfliktforskning;

    Abstract : This dissertation expands the inquiry of United Nations peace operations to incorporate their effects on gender power-relations of the host state. To achieve this, a mainstream-based analytical framework, additionally informed by suggestions from feminist research, was formulated and applied to the case of Timor-Leste. READ MORE

  6. 4. Fundamental Studies of Catalytic NOx Removal - Micro Kinetic Modelling, Monte Carlo Simulations and Flow Reactor Experiments

    Author : Louise Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NO oxidation; Monte Carlo simulations; platinum oxide; kinetic modelling; NOx storage; barium oxide; environmental catalysis; NOx removal; platinum; flow reactor measurements;

    Abstract : It is essential to decrease the CO2 emissions from vehicles, since CO2 is a greenhouse gas. One way to improve fuel economy and decrease CO2 emissions, is to run the engine with oxygen excess, so-called lean-burn operation. However, a major problem here is the reduction of the NOx in a lean atmosphere. READ MORE
