  1. 1. Catecholaminergic neurotransmission in heart and brain : development of tracers for positron emission tomography

    Författare :Claus Oliver Langer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :PET; Radioligand; Catecholamine; Norepinephrine; Dopamine; Heart; Brain; Metaraminol; Dopamine D2 Receptor;

    Sammanfattning : The catecholamines norepinephrine and its biosynthetic precursor dopamine are two principal neurotransmitters in the human central nervous system (CNS). Moreover, norepinephrine is a major transmitter substance in the peripheral, autonomic nervous system. LÄS MER

  3. 2. Lp-contractivity of Semigroups Generated by Linear Partial Differential Operators

    Författare :Mikael Langer; Stig Larsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is devoted to the study of contraction semigroups generated by linear partial differential operators. It is shown that linear partial differential operators of order higher than two cannot generate contraction semigroups on (LP)N for p ∈ [1, oo) unless p = 2. LÄS MER

  4. 3. Asymptotic analysis of solutions to elliptic and parabolic problems

    Författare :Peter Rand; Vladimir Kozlov; Mikael Langer; Vitali Liskevich; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Asymptotic behaviour; The Emden-Fowler equation; Parabolic system; Spectral splitting; Cylinder; Perturbation; MATHEMATICS; MATEMATIK;

    Sammanfattning : In the thesis we consider two types of problems. In Paper 1, we studysmall solutions to a time-independent nonlinear elliptic partial differential equation of Emden-Fowler type in a semi-infnite cylinder. The asymptotic behaviour of these solutions at infnity is determined. First, the equation under the Neumann boundary condition is studied. LÄS MER

  7. 5. Skönlitterär läsning och historiemedvetande hos barn i mellanåldrarna

    Författare :Mary Ingemansson; Anders Ohlsson; Gunlög Fur; Birgitta Svensson; Växjö universitet; []

    Sammanfattning : “ if you only read the book … you get the knowledge into your head once. If you talk about it, you get a more distinct memory of it, I think” (Emma, 11)This thesis shows how a novel by Maj Bylock, Drakskeppet, was used in education within thematic work, the Viking Age, among ten-year-olds and eleven-year-olds for five weeks.
