  1. 1. Actions and interactions of insulin-like growth factor-I and insulin in vascular smooth muscle

    Författare :Karin E. Bornfeldt; Ulf Smith; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Insulin-like growth factor-I (IGF-I) is a polypeptide with structural and biological similarities with insulin, and the receptors for IGF-I and insulin are homologous. The present investigation was devoted to the actions and interactions of IGF-I and insulin in vascular smooth muscle. LÄS MER

  3. 2. The hidden life of plants : fine root dynamics in northern ecosystems

    Författare :Gesche Blume-Werry; Roland Jansson; Ann Milbau; Scott D. Wilson; Isla Myers-Smith; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; belowground; boreal; climate change; fine roots; heath; meadow; minirhizotron; permafrost; phenology; plant community; root biomass; root growth; root litter; root production; subarctic; tundra;

    Sammanfattning : Fine roots constitute a large part of the primary production in northern (arctic and boreal) ecosystems, and are key players in ecosystem fluxes of water, nutrients and carbon. Data on root dynamics are generally rare, especially so in northern ecosystems. LÄS MER

  4. 3. Topics in Computational Algebraic Geometry and Deformation Quantization

    Författare :Christine Jost; Sandra Di Rocco; Boris Shapiro; Gregory G. Smith; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segre classes; Chern-Schwartz-MacPherson classes; topological Euler characteristic; computational algebraic geometry; numerical algebraic geometry; numerical homotopy methods; deformation quantization; polyvector fields; Fedosov quantization; Grothendieck-Teichmüller group; Mathematics; matematik;

    Sammanfattning : This thesis consists of two parts, a first part on computations in algebraic geometry, and a second part on deformation quantization. More specifically, it is a collection of four papers. In the papers I, II and III, we present algorithms and an implementation for the computation of degrees of characteristic classes in algebraic geometry. LÄS MER

  5. 4. Hilbert schemes and Rees algebras

    Författare :Gustav Sædén Ståhl; David Rydh; Karen Smith; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : The topic of this thesis is algebraic geometry, which is the mathematical subject that connects polynomial equations with geometric objects. Modern algebraic geometry has extended this framework by replacing polynomials with elements from a general commutative ring, and studies the geometry of abstract algebra. LÄS MER

  7. 5. Crash Courses in Belonging : The Emergence and Progression of a National Orientation in Instructional Materials for Adult Immigrant Language Instruction in Sweden and Denmark ca. 1960-2005

    Författare :William Wickersham; Historia; []
    Nyckelord :HUMANIORA; HUMANITIES; integration; assimilation; immigration; language instruction; policy; nationalism; national identity; belonging; textbooks; A.D. Smith; inclusion; exclusion; nation state;

    Sammanfattning : This dissertation explores representations of Sweden and Denmark and how immigrants’ place in Sweden and Denmark are represented in instructional materials for adult learners in the period ca. 19602005. LÄS MER
