  1. 1. A Study of Smooth Functions and Differential Equations on Fractals

    Författare :Anders Pelander; Anders Öberg; Svante Janson; Alexander Teplyaev; Tom Lindström; Uppsala universitet; []
    Nyckelord :Mathematical analysis; Analysis on fractals; p.c.f. fractals; Sierpinski gasket; Laplacian; differential equations on fractals; infinite dimensional i.f.s.; invariant measure; harmonic functions; smooth functions; derivatives; products of random matrices; Matematisk analys;

    Sammanfattning : In 1989 Jun Kigami made an analytic construction of a Laplacian on the Sierpiński gasket, a construction that he extended to post critically finite fractals. Since then, this field has evolved into a proper theory of analysis on fractals. The new results obtained in this thesis are all in the setting of Kigami's theory. LÄS MER

  3. 2. Understanding Opioid Therapy in Chronic Pain : Assessment, Lived Experience and Conceptions

    Författare :Hanna Ljungvall; Pernilla Åsenlöf; Nitya Jayaram-Lindström; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : The overarching aim of this thesis was to improve the understandings of opioid therapy for chronic non-cancer pain (CNCP) by examining the feasibility of different assessment methods of substance use, and opioid use disorder (OUD), and exploring the sense-making of opioid therapy in CNCP.  Methods: In study I, the reliability of the Addiction Severity Index Self-Report form (ASI-SR) was assessed by the agreement (intraclass correlation (ICC)) between the composite scores (CS) of the ASI interview and the ASI-SR, internal consistency of the CS subscales measured with Cronbach’s α, and sensitivity and specificity of the alcohol and drug CS’s, using Receiver Operating Characteristics analyses.

  4. 3. Deepening the insights of lignin structure : Lignin-carbohydrate complex (LCC) fractionation and characterization and Kraft lignin amination

    Författare :Xueyu Du; Jiebing Li; Mikael Lindström; Jussi Sipilä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Improvement of kraft pulping delignification efficiency and value-addition of industrial kraft lignin are two attractive topics. The proposal that delignification is deteriorated by the presence of lignin-carbohydrate complex (LCC) is still being debated. LÄS MER

  5. 4. Cattle Shipments and Disease Spread Modeling

    Författare :Peter Brommesson; Tom Lindström; Uno Wennergren; Angela Luis; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Spread of transboundary animal diseases can have large impact on animal welfare, public health and economy. The effects of this include economic losses in terms of lower milk production, lower weight gain and culling due to welfare concerns. LÄS MER

  7. 5. Studies of transforming growth factor alpha in normal and abnormal growth

    Författare :Anna-Lotta Hallbeck; Åke Wasteson; Thomas Walz; Annelie Lindström; Carl-Henric Heldin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-alpha; HER; EGFR; synovia; synovial sarcoma; RA; synovitis; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : Regulation of growth is of fundamental importance for development of the organism and to maintain health. The induction of cell proliferation and matrix production are influenced by several different signaling systems, most importantly by growth factors. LÄS MER
