2. 1. Making Radical Cations Live Longer

   Author : Ola Persson; Kemisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin trapping.; 3-hexafluoropropan-2-ol; 3; 1; thallium III -based oxidants; Radical cations; electron paramagnetic resonance; Physics; Fysik; Chemistry; Kemi;

   Abstract : The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. READ MORE

4. 2. Scaling sufficiency : Towards less material consumption

   Author : Ola Persson; Karin Bradley; Mikael Klintman; Kersty Hobson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Urban and Regional Studies; Urbana och regionala studier;

   Abstract : Various researchers have pointed out that avoiding further catastrophicconsequences related to the deteriorating ecological state of the planet,brought about by unsustainable production and consumption patterns,requires not only technological innovation and efficiency in productionprocesses, but also absolute reductions in energy and material use (i.e. READ MORE

6. 4. The burden of stroke in Sweden : studies on costs and quality of life based on Riks-Stroke, the Swedish stroke register

   Author : Ola Ghatnekar; Eva-Lotta Glader; Kjell Asplund; Ulf Persson; Ingvar Karlberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; atrial fibrillation; cost of illness; utility; mapping; Sweden; hälso- och sjukvårdsforskning; health services research;

   Abstract : The costs for stroke management and reduced health related quality of life (QoL) can extend throughout life as mental and physical disabilities are common. The aim of this thesis was to quantify this stroke-related burden with data from Riks-Stroke (RS), the Swedish stroke register. READ MORE

7. 5. Cation adsorption properties of substituted kraft fibres : an experimental and thermodynamic modelling study

   Author : Ola Sundman; Lars-Olof Öhman; Per Persson; Janne Laine; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kraft fibres; Donnan equilibria; ion exchange; acid base properties; potentiometric titrations; thermodynamic modelling; NPEs; GaAl12 7 ; EXAFS; Chemistry; Kemi;

   Abstract : Acid/base and metal ion adsorption properties have been investigated for a range of chemically modified bleached Kraft fibre materials (pulps). The studies were performed via potentiometric titrations, Flame Atomic Absorbtion (and Emission) Spectroscopy, Inductively Coupled Plasma Optical Emission Spectroscopy and Extended X-ray Absorbtion Fine Structure measurements.
