  1. 16. Studies on adipose tissue, body fat, body water and energy expenditure during the first four months of infancy using magnetic resonance imaging, skinfold measurements and the doubly labelled water method

    Author : Elisabeth Olhager; Kim Fleischer Michaelsen; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : During recent years much interest has been focused on the relationship between early nutrition and the future health of humans. Poor growth during early life has been associated with impaired glucose tolerance and coronary heart disease later in life, while rapid weight gain in infancy has been associated with an increased risk of obesity during childhood.

  2. 17. Stereoelectronic effects in nucleosides and nucleotides

    Author : Christophe Thibaudeau; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; Bioorganisk kemi; Bioorganic chemistry; Bioorganisk kemi; bioorganisk kemi; Biorganic Chemistry;

    Abstract : This thesis is based on 12 original publications from 1994-98. Intramolecular stereoelectronicforces (anomeric and gauche effects), beside intermolecular forces such as hydrogen bonding,base stacking, electrostatics and hydration, have been found to be responsible for the localstructural changes of DNA and RNA and their components.

  3. 18. Water-Induced Charge Transport in Microcrystalline Cellulose

    Author : Martin Nilsson; Maria Strømme; Göran Alderborn; Jürgen Einfeldt; Uppsala universitet; []
    Keywords : Materials science; Materialvetenskap;

    Abstract : Microcrystalline cellulose (MCC) is the most frequently used excipient for direct compaction of tablets within the pharmaceutical industry. It has earlier been indicated that the interactions between the hydration shell – surrounding the drug molecules in an MCC tablet – and the cellulose regulate the speed of the drug release process.

  4. 19. Iron-nitrogen containing carbon catalysts for oxygen reduction in fuel cells

    Author : Caroline Janson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; active site; mesoporous carbon; fuel cell; electron paramagnetic resonance; oxygen reduction reaction; cathode catalyst; non-precious metal catalyst;

    Abstract : New solutions to efficiently convert energy are needed to mitigate global climate changes and sustain the needs of the growing population. An energy device with high potential is the proton exchange membrane (PEM) fuel cell. PEM fuel cells can convert chemical energy to electrical energy with extraordinary high conversion efficiency.

  5. 20. Alkylglucosides - physical chemical properties

    Author : Frederik Nilsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Abstract : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. READ MORE
