  1. 1. Endocrine disrupting compounds in effluent waters : Chemical analysis to evaluate exposure of fish

    Författare :Maria Pettersson; Lillemor Asplund; Leif Kronberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Sammanfattning : The aim of this thesis was to investigate if endocrine disruption related to the release of estrogenic and/or androgenic substances via sewage treatment plant and pulp mill effluents is significant in Swedish waters. Chemical analysis of bile fluid in combination with measurement of biomarkers was used for the evaluation of internal exposure and effects in fish. LÄS MER

  3. 2. Legal preconditions for wind power implementation in Sweden and Denmark

    Författare :Maria Pettersson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Law; Rättsvetenskap;

    Sammanfattning : Swedish energy policy relies heavily on the promotion of renewable energy resources, in particular wind energy and in 2002 the Swedish Government adopted a national planning goal of a yearly wind power generation of 10 TWh by 2015, which implies a substantial increase from the current 0.6 TWh level.

  4. 3. On Fluid Power Piston Pumps : With Special Reference to Flow Ripple Reduction

    Författare :Maria Pettersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Among the major disadvantages of fluid power systems, leakage and an unpleasant sound level can be mentioned. Both drawbacks increase with increasing pressure ripple. Functional problems may be caused, even fatigue and breakdown. A main source of noise is hydrostatic pumps. LÄS MER

  5. 4. On the improvement of low frequency sound insulation in wooden buildings

    Författare :Maria Pettersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Wooden multi-family residential houses continue to gain in popularity. Compared to concrete, wooden constructions have low mass and are subject to relatively poor sound insulation at low frequencies. LÄS MER

  7. 5. Renewable energy and the function of law : a comparative study of legal rules related to the planning, location and installation of windmills

    Författare :Maria Pettersson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Law; Rättsvetenskap;

    Sammanfattning : Swedish energy policy relies heavily on the promotion of renewable energy, in particu-lar wind power. Notwithstanding a substantial political and economic support for this development, the installed capacity of wind power in Sweden remains fairly small both in relation to the corresponding development in other countries and in absolute num-bers.
