  1. 1. Atmospheric corrosion and runoff processes on copper and zinc as roofing materials

    Författare :Wenle He; KTH; []
    Nyckelord :atmospheric corrosion; corrosion rate; runoff rate; copper; zinc; field study; laboratory study; roof; first flush; rain quantity; rain intensity; rain pH; dry and wet deposition; corrosion and runoff process;

    Sammanfattning : An extensive investigation with parallel field andlaboratory exposures has been conducted to elucidateatmospheric corrosion and metal runoff processes on copper andzinc used for roofing applications. Detailed studies have beenperformed to disclose the effect of various parameters on therunoff rate including: surface inclination and orientation,natural patination (age), patina composition, rain duration andvolume, rain pH, and length of dry periods inbetween rainevents.

  3. 2. Numerical approaches to droplet growth in atmospheric turbulence

    Författare :Xiang-Yu Li; Axel Brandenburg; Gunilla Svensson; Luca Brandt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; turbulence; coagulation; condensation; rain formation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The bottleneck problem of cloud droplet growth is one of the most challenging problems in cloud physics. Cloud droplet growth is neither dominated by con-densation nor gravitational collision in the size range of 15–40 μm in radius. Turbulence-generated collision has been thought to be the mechanism to bridge the size gap, i.e. LÄS MER

  4. 3. Impact of moisture on long term performance of insulating products based on stone wool

    Författare :Tomás Vrána; Folke Björk; Per Ingvar Sandberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral insulation; Stone wool; Material properties; Moisture transport; Heat transport; Test equipment; Moisture properties; Frost formation; Building engineering; Byggnadsteknik;

    Sammanfattning : Demands for energy have been increasing in the whole world. According to higher consumption, the price of energy rises yearly too. This evokes usage of insulating products in a wider range. LÄS MER

  5. 4. The voice of the people? : Supplications submitted to the Swedish Diet in the Age of Liberty, 1719–1772

    Författare :Martin Almbjär; Svante Norrhem; Peter Lindström; Nils Erik Villstrand; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Age of Liberty; audit; Diet of Estates; early modern state formation; eighteenth century; institutions; national debt; parliamentary committees; petitions; political participation; public office; supplications; taxes; trade privileges; Supreme Court; welfare; historia; History;

    Sammanfattning : This dissertation is devoted to the study of who used the formal channels of interaction in the early modern era and why. It examines the full range of the political conversation in early modern Sweden, as seen in the supplications to the Diet in the Age of Liberty (1719–1772), and more specifically the supplications submitted to the parliamentary committee tasked with handling them, the Screening Deputation.

  7. 5. Environmental taxation - Empirical and Theoretical Applications

    Författare :Åsa Löfgren; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Oil; Decomposition; Gasoline; Policy instruments; Causality; Political economy; Optimal taxation; Habit formation; Environment; Intertemporal choice;

    Sammanfattning : This thesis consists of five self-contained articles, and hence each paper can be read independently. Still, all five papers have one important feature in common: environmental taxation. LÄS MER
