  1. 1. Carbohydrate dynamics and interactions studied by NMR spectroscopy

    Författare :Olof Engström; Göran Widmalm; Niklas Hedin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The combination of NMR spectroscopy and molecular dynamics (MD) simulations are powerful tools in the studying of bioorganic molecules in solution. In this thesis two such studies are presented with focus on the NMR aspect. LÄS MER

  3. 2. Exploring the Molecular Behavior of Carbohydrates by NMR Spectroscopy : Shapes, motions and interactions

    Författare :Olof Engström; Göran Widmalm; Anthony S. Serianni; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; NMR relaxation; DNMR; CORCEMA-ST; carbohydrates; caffeine; O-antigen; glycofullerenes; organisk kemi; Organic Chemistry;

    Sammanfattning : Carbohydrates are essential biomolecules that decorate cell membranes and proteins in organisms. They are important both as structural elements and as identification markers. Many biological and pathogenic processes rely on the identification of carbohydrates by proteins, thereby making them attractive as molecular blueprints for drugs. LÄS MER

  4. 3. Möjligheter till lärande i matematik : Lärares problemformuleringar och dynamisk programvara

    Författare :Lil Engström; Thomas Lingefjärd; Per-Olof Wickman; Ole Björkqvist; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cabri Geometry; dynamic geometry software; mathematics teaching; teachers problem posing; Matematikdidaktik; dynamisk programvara; problemformulering; undervisning; Education; Pedagogik;

    Sammanfattning : This thesis presents the first Swedish empirical evidence on how teachers employ a dynamic mathematical software when teaching mathematics in upper secondary school. The study examines: a) How teachers formulate mathematical problems? b) How they use the experience the students have gained? and c) What use they make of the software’s potential? These questions are examined through classroom observations followed up by discussions with the teachers. LÄS MER
