  1. 1. Ternary Block Copolymer Systems - Phase Behaviour and Phase Structure

    Författare :Birgitta Svensson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; lyotropic; thermotropic; SANS; SAXS; scattering; semicrystalline; reverse micelle; micellar solution; liquid crystalline; phase diagram; phase behaviour; block copolymer; pluronic; poly ethylene oxide ; poly propylene oxide ; quantum chemistry; Teoretisk kemi; kvantkemi;

    Sammanfattning : Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembly of block copolymers. The phase behaviour has been studied at varied block copolymer molecular weight and relative PEO/PPO block ratio. LÄS MER

  3. 2. Treatment process and outcome for long-term mentally ill patients in a comprehensive treatment program based on cognitive therapy

    Författare :Bengt Svensson; Lund Psykiatri; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psykiatri; psychosomatics; clinical psychology; schizophrenia; Cognitive theraphy; therapeutic alliance; Psychiatry; milieu therapy; klinisk psykologi; psykosomatik;

    Sammanfattning : All patients admitted during a four-year period to a comprehensive, cognitive therapy based inpatient rehabilitation program for long-term mentally ill were invited to participate in the present study. A total of 28 patients were included. LÄS MER

  4. 3. The role of leucine-rich repeat glycoproteins/proteoglycans in the assembly of collagen matrices

    Författare :Liz Svensson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reumatologi; muskelsystem; Skelett; decorin; Collagen; fibromodulin; extracellular matrix; lumican; collagen fibrillogenesis; Skeleton; rheumatology locomotion; muscle system; Biochemistry; Biokemi; Metabolism;

    Sammanfattning : The properties of different connective tissues depend on the synthesis and assembly of macromolecular structures composed of collagen and other extracellular matrix components. Mechanisms modulating these events play important roles in the formation of a functional tissue. LÄS MER

  5. 4. Structural and mechanistic aspects of alcohol dehydrogenase function

    Författare :Stefan Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Vertebrates possess a complex alcohol dehydrogenase (ADH) system composed of multiple molecular forms, which are currently classified into seven classes according to their structural properties. ADHs are dimeric zinc metalloenzymes that catalyze the reversible oxidation of alcohols to aldehydes/ketones using NAD+/NADH as electron acceptor and donor, respectively. LÄS MER

  7. 5. Tracking Chambers with Two-Dimensional Readout used for Extraction of Particle Production Ratios in High Multiplicity Pb+Pb Collisions at 158 A GeV

    Författare :Tomas Svensson; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; position resolution; wire chamber pixel readout; pad readout; tracking; multi-step avalanche chamber; Fysik; Physics; particle ratios;

    Sammanfattning : Heavy-ion collisions at high energies calls for new technical solutions to cope with the very high multiplicities of produced particles. In this thesis the design and development of two types of tracking chambers for high multiplicity environments are presented. LÄS MER
