  1. 16. Trace metal speciation in fresh and brackish waters using ultrafiltration, DGT and transplanted aquatic moss

    Författare :Jerry Forsberg; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Distribution, mobility, and toxicity of metals in natural waters are strongly related to their aqueous speciation. To understand the behaviour of an aqueous element and the transformation between chemical species, there is a need for reliable methods that enable measurements of specific fractions of metals.

  3. 17. Elements in regulation of the microfilament system

    Författare :Louise Hillberg; Uno Lindberg; Theresia Stradal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell motility; microfilament system; actin; tropomyosin; Cell and molecular biology; Cell- och molekylärbiologi; Cell Biology; cellbiologi;

    Sammanfattning : This thesis deals with cell motility. The process of rapid actin polymerization in the lamellipodium of a migrating cell is responsible for its protrusion. Studies have been made on some of the elements behind this event and special interest has been focused on the protein tropomyosin. LÄS MER

  4. 18. Analysis of Complement Deficiency States. With Focus on Molecular Characterization of C4 and Properdin Deficiency

    Författare :Gunilla Nordin Fredrikson; Kardiovaskulär forskning - immunitet och ateroskleros; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; virology; bacteriology; Complement C4; Complement; Complement Screening; Deficiency; Meningococcal Disease; Properdin; Properdin Expression; Microbiology; Sequencing; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Complement deficiency is associated with an increased risk for invasive infection and immune complex disease. Screening for identification of complement-deficient patients is essential and a new ELISA-based procedure for detection of complement deficiency is described. LÄS MER

  7. 20. Properties of humic substances from groundwater and surface waters

    Författare :Catharina Pettersson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Humic substances play an important role in the environment. The aim of this thesis is to enhance the understanding of the behaviour of humic substances in natural waters and their importance for mobilizatiou/immobilization, redistribution, bioavailability and removal of metals and organic pollutants from aqueous systems.
