  1. 11. Swelling and Mechanical Properties of Polymer Gels: Salt, Macroion and Network Topology Effects

    Författare :Samuel Edgecombe; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; volume decrease upon uniaxial extension; interpenetrating networks; loose-end effects; polydispersity effects; macroion deswelling; salt deswelling; polymer gels; polyelectrolyte gels; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The work in this thesis concerns polymer gels, especially their swelling and mechanical properties modelled using a coarse-grained model of polyelectrolytes. The method used to study polymer gels was molecular simulation utilising the simulation package MOLSIM. LÄS MER

  3. 12. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements

    Författare :Annika Lundmark; Per-Erik Jansson; Bo Olofsson; Ann-Catrine Norrström; Helen K. French; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chloride; De-icing salt; Groundwater; Modelling; Monitoring; Road; Roadside; Soil water; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. LÄS MER

  4. 13. Iodine intake and uptake in populations at risk for iodine deficiency

    Författare :Sofia Manousou; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; iodine; pregnancy; lactation; bariatric surgery; urinary iodine concentration; thyroglobulin; breastmilk iodine concentration; iodine supplementation; Sweden;

    Sammanfattning : Background: Iodine is essential for the production of thyroid hormones. Both iodine deficiency (ID) and iodine excess may be harmful. Iodine intake in Sweden is considered adequate for the general population due to iodization of table salt since 1936 but data on pregnant and breastfeeding women (i.e. LÄS MER

  5. 14. Interactions in aqueous salt solutions : Atomistic modelling versus experiment

    Författare :Vidar Aspelin; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistisk mekanik; molekylär modellering; MD simuleringar; MC simuleringar; statistical mechanics; molecular simulation; MD simulations; MC simulations; Kirkwood-Buff theory; Hofmeister series;

    Sammanfattning : The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). LÄS MER

  7. 15. Strain quantifications in different tectonic scales using numerical modelling

    Författare :Lukas Fuchs; Hemin Koyi; Susanne Buiter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Deformation modelling; progressive and finite deformation; salt tectonics; down-built diapir; upper mantle; lithosphere-asthenosphere boundary; seismic anisotropy; plate-mantle de coupling; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : This thesis focuses on calculation of finite and progressive deformation in different tectonic scales using 2D numerical models with application to natural cases. Essentially, two major tectonic areas have been covered: a) salt tectonics and b) upper mantle deformation due to interaction between the lithosphere and asthenosphere. LÄS MER
