  2. 1. Physical properties of coarse particles in till coupled to bedrock composition based on new 3D image analysis method

    Author : Solomon Tafesse; Joanne Fernlund; Tore Påsse; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Three-dimensional shape; Grain size; Till lithology; Natural aggregate; Till provenance; Magnetic susceptibility of rock; Physical property of till; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Geoengineering; Geoteknik;

    Abstract : The physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. READ MORE

  4. 2. Studies of X-Ray Optics And Polarimetry For Synchrotron Radiation

    Author : Walan Grizolli; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray optics; polarimetry; synchrotron radiation instrumentation.;

    Abstract : Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies have made possible to obtain very low emittance electron beams, which together with the use of undulators allow to guide a very high photon flux into a very small beam size required by the experiments.

  5. 3. Hydrophobically Modified Polymers. Rheology and Molecular Associations

    Author : Leif Karlson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer self diffusion; Physical chemistry; Fysikalisk kemi; rheology; hydrophobically modified polyethylene glycol; hydrophobically modified ethyl hydroxyethyl cellulose; cyclodextrin; hydrophobically modified polymer; associative thickener;

    Abstract : Structure- property relationships and thickening mechanism in aqueous solution of two hydrophobically modified polymers (HM-P) with different architecture have been investigated. The two polymers, hydrophobically modified ethyl hydroxyethyl cellulose (HM-EHEC) and hydrophobically modified polyethylene glycol (HM-PEG), are commonly used as associative thickeners in the paint industry.

  6. 4. Polymer Gels and their Interactions with Ionic Surfactants

    Author : Olof Rosén; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Polymer-Surfactant Interactions; Modified Polymers; Binding Isotherm; Polymer Gels; Swelling Isotherm; Fysikalisk kemi;

    Abstract : The response on chemically crosslinked gels and polymer solutions on the addition of ionic surfactants and/or addition of salt at different temperatures have been studied. All polymers studied are water soluble and slightly hydrophobic or hydrophobically modified. READ MORE

  7. 5. Life paths through space and time: Adding the micro-level geographic context to longitudinal historical demographic research

    Abstract : Historical demographic research is central to understanding past human behaviours and traits, such as fertility, mortality and migration. An essential part of historical demography is conducting longitudinal analyses at the micro-level, which involves the detailed follow-up of individuals over long time periods throughout their lives.
