  4. 3. Sterically stabilised liposomes and related lipid aggregates : Fundamental studies on aggragate structure and stability

    Författare :Markus Johnsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; liposome; steric stabilisation; colloidal stability; cryo-TEM; drug delivery; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Various aspects of and approaches towards the steric stabilisation of liposomes have been investigated, mainly by use of fluorescence techniques and cryo-transmission electron microscopy (cryo-TEM). It is shown that PEG(2000)-lipids can be incorporated in the liposome membrane up to a critical concentration of 8-10 mol% without any observable structural perturbations. LÄS MER

  5. 4. Strength of Stabilised Soil - A Laboratory Study on Clays and Organic Soils Stabilised with different Types of Binder

    Författare :Helen Åhnberg; Byggnadskonstruktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Hållfasthet; Geoteknik; Stabiliserad jord; materialteknik;

    Sammanfattning : Stabilisation of soft soils by deep mixing with binders is the most frequently used method of ground improvement in Sweden today, and is increasingly being used internationally. The most common binders employed are cement and lime, but a variety of other binders may also be used for stabilisation of soils. LÄS MER

  7. 5. Compaction- and strength properties of stabilised and unstabilised fine-grained tills

    Författare :Per Lindh; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Väg- och vattenbyggnadsteknik; Compaction; Fine-grained tills; Strength; Civil engineering; Soil stabilisation modification; hydraulic engineering; soil mechanics; offshore technology; Material technology; Materiallära; materialteknik;

    Sammanfattning : Fine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. LÄS MER
