  2. 1. 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

  4. 2. Studies of Volcanic Influence on Aerosols, Clouds and Climate

    Author : Johan Friberg; Ergonomi och aerosolteknologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lowermost stratosphere; volcanic aerosol; upper troposphere; sulfurous aerosol; carbonaceous aerosol; ion beam analysis; volcanism; indirect effect; radiative forcing; direct effect; Stratosphere; Fysicumarkivet A:2016:Friberg;

    Abstract : This thesis focuses on the influence of volcanism on the compositions of the aerosols in the upper troposphere (UT) and lowermost stratosphere (LMS), and their direct and indirect impact on climate. Aerosol data were obtained by aircraft-borne sampling, using the CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) platform, and laboratory-based ion beam analysis of aerosol samples at the Lund Ion Beam Analysis Facility (LIBAF).

  6. 4. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods

    Author : Bart Eduard Jan Pelssers; Jan Conrad; Jochen Schieck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; direct detection; statistical analysis; fysik; Physics;

    Abstract : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. READ MORE

  7. 5. Direct and indirect magnetocaloric properties of first- and second-order phase transition materials

    Author : Sagar Ghorai; Peter Svedlindh; Martin Sahlberg; Gabriella Andersson; Ekkes Brück; Uppsala universitet; []
    Keywords : Magnetocaloric effect; Adiabatic temperature change; Direct measurement of magnetocaloric effect; Griffiths phase; Magneto-elastic transition; Magneto-structural transition; Second-order magnetic phase transition; First-order magnetic phase transition; Isothermal magnetic entropy change; Fysik; Physics;

    Abstract : The energy-efficient and environmentally friendly alternative cooling technology based on the magnetocaloric effect (MCE) is discussed in this thesis. The thesis has two major parts, one devoted to material characterization and the other to instrument development. READ MORE
