  1. 1. Endothelin and nitric oxide in the fetoplacental circulation

    Författare :Anna Sand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Fetoplacental circulation; placental arteries; endothelin-1; nitric oxide; potassium channels; M-CSF; endothelin receptors; BKCa; ETA; ETB;

    Sammanfattning : Background: Normal fetal growth and development depend on a satisfactory uteroplacental and fetoplacental blood flow. This will ensure an adequate gaseous exchange and nutritional supply to the fetus. LÄS MER

  4. 3. Nonlinear finite element simulations of ice forces on offshore structures

    Författare :Björnar Sand; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The present investigation has been devoted to the development of nonlinear finite element simulations by means of obtaining ice forces on structures. The effects of material nonlinearities and friction between ice and structure are taken into account. LÄS MER

  5. 4. Neuroimmune Interactions of Enteric Neurons and Mast Cells: Friends or Foes?

    Författare :Elin Sand; Neurogastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enteric neurons; ischemia; VIP; mast cells; CRF;

    Sammanfattning : Psychological distress or physical strain lead to reduced blood flow in the intestine since other organs are prioritised. One aim of this thesis was to investigate how ischemia followed by reperfusion affects the large intestine and the enteric nervous system (ENS). LÄS MER

  7. 5. Stability and boundedness results for variable-step variable-formula methods

    Författare :Jørgen Sand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This work constitutes the author's Doctoral thesis, which includes an introduction to and a summary of the following two TRITA-NA-reports: 8112 and 8218.In many practical applications one is interested in step-wise simulation of the behaviour of a dynamic system described by ordinary differential equations.
