  2. 11. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons

    Author : Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Flake graphite; Compacted graphite; Spheroidal graphite; Elastic deformation; Plastic deformation; Modulus of elasticity; Graphite modulus of elasticity; Strength coefficient; Strain hardening exponent; Acoustic emission; Construction materials; Konstruktionsmaterial;

    Abstract : The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. READ MORE

  4. 12. Methodologies to assess the fate of polar organic compounds in aquatic environments

    Author : Jörgen Magnér; Tomas Alsberg; Dag Broman; Jan-Åke Jönsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Passive equilibrium sampler; Absorbent; Polar organic compounds; Liquid chromatography-mass spectrometry; Partitioning coefficient; Fulvic acid; Sediment; PEVAC; Bag-SPE; Solid phase extraction; Pharmaceuticals; Wastewater; Sea water; UPLC-QToF; Environmental chemistry; Miljökemi; Analytical chemistry; Analytisk kemi; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements.

  5. 13. Reliability-based evaluation of concrete dams

    Author : Marie Westberg; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatial correlation; assessment; concrete dam; uplift; structural reliability analysis; existing structure;

    Abstract : Swedish concrete dams are designed and assessed based on deterministic design using safety factors. The combination of increasing age, new methods for calculation of design floods and increasing demands by society to ensure a high level of safety, has resulted in upgrading and rebuilding needs for dams.

  6. 14. Towards a simulation methodology for prediction of airborne wear particles from disc brakes

    Author : Jens Wahlström; Ulf Olofsson; Jens Wahlström; KTH; []
    Keywords : Disc brakes; Airborne wear particles; Particle coefficient; Friction; Mechanical engineering; Maskinteknik;

    Abstract : During braking, both the rotor and the pads in disc brakes are worn. Since disc brakes are not sealed, some of the wear particles generated can become airborne. READ MORE

  7. 15. Solid-liquid Phase Equilibria and Crystallization of Disubstituted Benzene Derivatives

    Author : Fredrik Nordström; Åke Rasmuson; Gerard Coquerel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Salicylic acid; m-hydroxybenzoic acid; p-hydroxybenzoic acid; salicylamide; m-aminobenzoic acid; p-aminobenzoic acid; solubility; solid-liquid equilibria; thermodynamics; activity of the solid phase; ideal solubility; activity coefficient; van t Hoff enthalpy of solution; solid state; solution properties; metastable zone width; primary nucleation; nucleation kinetics; Chemical engineering; Kemiteknik;

    Abstract : The Ph.D. project compiled in this thesis has focused on the role of the solvent in solid-liquid phase equilibria and in nucleation kinetics. Six organic substances have been selected as model compounds, viz. READ MORE
