  3. 2. Relict non-glacial surfaces and autochthonous blockfields in the northern Swedish mountains

    Författare :Bradley W. Goodfellow; Arjen Stroeven; Clas Hättestrand; Johan Kleman; Krister Jansson; Adrian Hall; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; blockfield; chemical weathering; cosmogenic exposure dating; glaciated landscape; northern Sweden; periglacial geomorphology; relict surface; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Sammanfattning : Relict non-glacial surfaces occur in many formerly glaciated landscapes, where they represent areas that have escaped significant glacial modification. Frequently distinguished by blockfield mantles, relict non-glacial surfaces are important archives of long-term weathering and landscape evolution processes. LÄS MER

  4. 3. Fibres in reinforced concrete structures - analysis, experiments and design

    Författare :Anette M Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crack width; stress crack-width relationship; design methods; post cracking; analysis method; Fibre-reinforced concrete;

    Sammanfattning : Potential benefits from fibres in concrete are improved crack control and the possibility of more slender structures. The extent of the crack control depends, among other factors, on the amount of fibres added, and plays a great role for durability. LÄS MER

  5. 4. Effects of Steel Fibres on Cracking in Reinforced Concrete

    Författare :Anette M Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uniaxial tension test; Keywords: Self-compacting; characteristic crack width; fibre-reinforced; bond; tension stiffening; Digital Image Correlation; pull-out test;

    Sammanfattning : ABSTRACTAlthough it is well known that fibre reinforcement acts as a crack arresting agent, there is still a need for deeper knowledge of the actual cracking behaviour, especially regarding cracks with widths smaller than 0.3mm. LÄS MER

  7. 5. Carbide and MAX-Phase Engineering by Thin Film Synthesis

    Författare :Jens-Petter Palmquist; Ulf Jansson; M. Jochen Schneider; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Thin films; microstructure; epitaxy; carbide; WC; MAX-phase; Ti3SiC2; DC magnetron sputtering; PVD; Reciprocal Space Mapping; RSM; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. LÄS MER
