  1. 21. Central pain in multiple sclerosis : clinical characteristics, sensory abnormalities and treatment

    Författare :Anders Österberg; Per Hansson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In the present research programme the occurrence of pain in MS was investigated, with special emphasis on central pain (CP). Questionnaires were sent to all 429 patients with definite MS in the patient register at our neurology department. LÄS MER

  3. 22. Optical characterization of Silicon-based self-assembled nanostructures

    Författare :Bouchaib Adnane; Wei-Xin Ni; Per Olof Holtz; Göran Hansson; Susumo Fukatsu; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This PhD thesis summarizes the work carried on the optical characterizations of some Si-based self-assembled nanostructures, particularly SiGe/Si quantum dots (QDs) and nanocrystalline (nc)-Si embedded in mesoporous silica (MS) using photoconductivity (PC), photoluminescence (PL), and photoluminescence excitation (PLE) measurements. The spectroscopic studies of SiGe/Si QDs grown on Si by molecular beam epitaxy revealed for the first time well-resolved PLE resonances. LÄS MER

  4. 23. Värdegrundsarbete i bildundervisning : en studie om iscensättning av policy i grundskolans senare år

    Författare :Hanna Ahrenby; Per-Olof Erixon; Stina Wikberg; Kristina Hansson; Eva Hultin; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; art education; fundamental values; citizenship education; democratic education; policy enactment; policy context; performativity; bildundervisning; skolans värdegrund; demokratiuppdrag; policystudie; undervisningskontext; pedagogiskt arbete; pedagogiskt arbete; educational work;

    Sammanfattning : The overall purpose of this thesis is to describe and discuss preconditions for the enactment and the construction of fundamental values in art education in secondary school. The study is based on ethnographic methods, including classroom observations, video recordings and interviews with art teachers and pupils. LÄS MER

  5. 24. Microgels as drug delivery vehicles : loading and release of amphiphilic drugs

    Författare :Yassir Al-Tikriti; Per Hansson; Magnus Bergström; Matthew Libera; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microgel; amphiphilic drug; phase separation; micropipette; Raman microscopy; controlled release; drug delivery; SAXS; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Sammanfattning : Polyelectrolyte microgels are used as delivery vehicles for amphiphilic drugs in, e.g., treatments of liver cancer by a method called trans-arterial chemoembolization. LÄS MER

  7. 25. Phase Phenomena in Polymer Networks : Empirical Studies on the Influence of Hydrophobicity, Charge Density and Crosslinks on Macroion-Induced Phase Transitions in Polyelectrolyte Gels

    Författare :Martin Andersson; Per Hansson; Lennart Piculell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gel; microgel; microsphere; polystyrenesulfonate; polyacrylate; polyacrylicacid; DoTAB; DoTAC; CTAB; CTAC; network; polyelectrolyte; complex salt; self assembly; phase behaviour; hysteresis; thermodynamic; core-shell; lysozyme; cytochrome c; microscopy; micromanipulator; elastomer; elastic; protein; surfactant; phase behaviour; sorting; PHARMACY; FARMACI; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The thesis concerns polyelectrolyte gels in contact with oppositely charged proteins and surfactant micelles, and includes of four papers (I-IV). In paper I confocal Raman spectroscopy was introduced as a method to trace micelles and investigate the structure of gel-surfactant complexes, in phase separated gel spheres. LÄS MER
