  1. 1. Synthesis of functional degradable polymers by radical ring-opening polymerization

    Författare :Jenny Undin; Ann-Christine Albertsson; Mats Johansson; Monica Ek; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; tissue engineering; ring-opening polymerization; 2; 2´-azoisobutyronitrile; cyclic ketene acetals; 2-methylene- 1; 3; 6-trioxocane; 2-methylene- 1; 3-dioxepane; vinyl acetate; coopolymerization;

    Sammanfattning : The increased demand for understanding cell-material interactions and subsequently create personalized implants for tissue engineering has resulted in an increased interest in developing new monomers with functional groups. The focus of the work presented in this thesis has been on the synthesis of functional monomers and the polymerization of these into functional amorphous aliphatic polyesters. LÄS MER

  2. 2. In Vitro Studies of the Substrate Specificities of Heparan Sulfate 2-O- and 6-O-sulfotransferases

    Författare :Emanuel Smeds; Marion Kusche-Gullberg; Ulf Lindahl; Catherine L. R. Merry; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; heparin; sulfotransferase; 2-O-sulfotransferase; 6-O-sulfotransferase; polysaccharide biosynthesis; glycosaminoglycan; O-sulfotransferase; proteoglycan; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Heparan sulfate (HS), a linear negatively charged polysaccharide located at the cell surface and in the extracellular matrix, interacts with, and thereby regulates the functions of numerous proteins. HS-protein interactions depend on the fine structure of HS, especially its sulfation pattern. LÄS MER

  3. 3. Paper-composite porcelain : characterisation of material properties and workability from a ceramic art and design perspective

    Författare :Kim Jeoung-Ah; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :HUMANIORA; HUMANITIES; Ceramic art and design; Paper clay; Porcelain;

    Sammanfattning : Paper-composite porcelain is a type of paper clay which is made by combining any kind of porcelain with paper. Paper is added to clay to improve low green strength and plasticity - two of the main practical problems of working with porcelain. LÄS MER

  4. 4. Att slåss för erkännande : en studie i gatuvåldets dynamik

    Författare :Björn Johansson; Mats Ekström; Malin Åkerström; Örebro universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; street related violence; crimes of violence; urban environment; virtual community; border controls; territoriality; social transactions; respect; honour; street etiquette; street wisdom; rituals; power; status; recognition; gangs; emotions; social bonds; sociologi; Sociology; Sociologi; Sociologi; Sociology;

    Sammanfattning : The aim of this thesis is to give a contribution to the knowledge of why people use violence against each other in public places. In more specific terms the thesis examines mechanisms that generates violent actions by reference to what happens in the situated transaction between the offender and the victim, and to the ways in which the urban environment create opportunities for violent actions.
