  2. 16. Stresses in high performance concrete due to temperature and moisture variations at early ages

    Author : Hans Hedlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis presents results from laboratory tests and numerical analyses of stress states in concrete structures arising from volume changes due to temperature and shrinkage during hydration. The laboratory tests presented here deal with: the determination of heat transfer coefficients for cooling pipes measurements of self-desiccation and shrinkage under sealed conditions deformation measurements under temperature and moisture changes and measurements of stress development during hardening for a fully restrained structural member.

  4. 17. Biophysical Studies of Apolipoprotein A-IM and a Partitioning study

    Author : Malin Suurkuusk; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apolipoprotein A-IMilano; Apolipoprotein A-I; Lipoprotein; Lipid; Microcalorimetry; DCS; Denaturation; Guanidine Hydrochloride; Physics; Fysik; Chemistry; Kemi;

    Abstract : The major part of this thesis deals with the similarities and differences in some biophysical properties of apolipoprotein A-I (apo A-I) and the molecular variant apolipoprotein A-IMilano (apo A-IM), and the influence on lipid binding. A model compound partitioning study has also been performed. READ MORE

  5. 18. Astrochemical Surface Science: Water Desorption from Nanostructured Graphite

    Author : Anna Clemens; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intercalation; temperature programmed desorption; diffuse reflection; geometrical resonances; water ice; ultra high vacuum;

    Abstract : To date, around 180 different molecules have been identified in the interstellar medium (ISM). Some of them form molecular ices on cold interstellar dust grain surfaces. An interstellar dust grain particle is in the order of nanometres in size and is usually composed of a carbonaceous or silicatious grain core. READ MORE

  6. 19. Magnetoresistance and Space : Micro- and Nanofeature Sensors Designed, Manufactured and Evaluated for Space Magnetic Field Investigations

    Author : Anders Persson; Hugo Nguyen; Greger Thornell; Johan Åkerman; Uppsala universitet; []
