  1. 1. Effects of Simulated Recycling on Polyolefin Materials

    Author : Anna Jansson; Anna L. Jansson; Chalmers University of Technology; []
    Keywords : recycling; oxidation; degradation; polyolefins;

    Abstract : Production and handling of waste is a matter of concern in most countries, and one way to reduce the amount of waste is recycling. Since synthetic polymers are made from non- renewable resources and are used in large amounts, often for short periods of time, they should be recycled in a sustainable society. READ MORE

  2. 2. The impact of age and gender with respect to general joint laxity, shoulder joint laxity and rotation : A study of 9, 12 and 15 year old students

    Author : Anna Jansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Competitive swimmers; drawer test; hypermobility; sulcus sign;

    Abstract : The overall aim of this thesis was to study the natural development of general joint laxity, shoulder joint laxity and shoulder joint rotation in young students, and compare these to age-matched competitive swimmers to detect possible discrepancies between these groups. A further aim was to evaluate the clinical examination techniques used whether they correlate to each other in search of better understanding and interpretation of achieved measurement results.

  3. 3. Structural enzymology of the biosynthesis of polyketide antibiotics

    Author : Anna Jansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; X-ray crystallography; anthracycline; polyketide; Streptomyces; S-adenosyl-Lmethionine; methyltransferase; hydroxylase; aldol-condensation.;

    Abstract : Anthracyclines are an important group of aromatic antibiotics that exhibit antitumour activity, which makes them useful in treatment of various cancers. They are synthesised in the polyketide biosynthetic pathway as secondary metabolites by different Streptomyces species. READ MORE

  4. 4. Development of Novel In Situ ESEM Techniques for the Study of Water Interaction with Soft Materials

    Author : Anna Jansson; Chalmers University of Technology; []
    Keywords : environmental scanning electron microscopy; cellulose fibre; water transport; swelling; osmotic shock; yeast cell; in situ; manipulator; water interaction;

    Abstract : The transport of water is central to many applications of soft biomaterials; for example water management in personal care products, controlled drug release in pharmaceuticals and, on a fundamental level, the activities of living cells. Water transport through a material may occur in both liquid and gas phase, and is highly dependent on the microstructure. READ MORE

  5. 5. Development of Novel In Situ Microscopy Techniques for the Study of Water Interaction with Soft Materials

    Author : Anna Jansson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; environmental scanning electron microscopy; polymer film; manipulator; yeast cell; swelling; in situ; water transport; cellulose fibre; osmotic shock; water interaction;

    Abstract : The transport of water in soft materials can occur in liquid or gas phase and is highly dependent on the material microstructure and the structure dynamics. Understanding these relationships is the basis for the development of predictive models that can aid the design of new and improved functional materials. READ MORE
