  2. 6. Microcalorimetric methods for direct measurement of solubility and solvent activity

    Author : Dennis Berling; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enthalpy of solution; solubility; solvent fugacity; solvent activity; Isothermal calorimetry; vapour pressure; Chemistry; Kemi;

    Abstract : New calorimetric methods for direct measurement of solubility and solvent activity are presented. The classical role of calorimetry for measurements of enthalpic parameters is abandoned and the technique is instead used for assessing thermodynamic quantities related to the chemical potential of a substance in a solution.

  4. 7. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance

    Author : Eric Berggren; Mats Berg; Laurent Schmitt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway track stiffness; maintenance; soil dynamics; measurement; simulation; vibration; Vehicle engineering; Farkostteknik;

    Abstract : Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. READ MORE

  5. 8. Digital Electrical DNA Sensing

    Author : Maoxiang Guo; Wouter van der Wijngaart; Fredrik Westerlund; KTH; []
    Keywords : DNA detection; thiol-ene-epoxy; rolling circle amplification; digital measurement; DNA stretching; microwell-array; gold nanowires; electrical measurement; specificity; limit of detection; liquid storage; disease diagnosis; lab-on-a-chip; point-of-care.;

    Abstract : Molecule detection is a workhorse in life sciences and medicine, for example in cancer diagnosis and virus and bacterial detection. DNA analysis can provide vital information about the state of a host organism and its medical and health condition. READ MORE

  6. 9. Influences, effects and changes from interventions by eco-labelling schemes - What a Swan can do?

    Author : Åke Thidell; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Direct effect; Eco-labelling; Intervention theory; Environmental labelling; Nordic Swan; Measurement method; Indirect effect;

    Abstract : Eco-labelling is a voluntary and informative policy instrument aiming at stimulating environmentally beneficial product development through using the market forces. The Nordic Swan eco-labelling scheme has been in operation since 1989. READ MORE

  7. 10. Direct writing with an MeV proton beam: Development and Applications

    Author : Vaida Auzelyte; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; direct writing; beam control; Physics; Fysik; Teknik; Technological sciences; proton beam; lithography; Fysicumarkivet A:2006:Auželytė;

    Abstract : This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. READ MORE
