    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Björn Karlsson; [2014]
    Keywords : Pollen; geokemi; bergsbruk; gruvbrytning; Garpenberg; Bergslagen; vegetationsförändringar; skog; jordbruk; pollen; geochemistry; mining; Sweden; vegetation changes; forest; farming;

    Abstract : Bergsbruket har under lång tid haft stor betydelse för Sverige både ekonomiskt och politiskt. Det har också haft en inverkan på naturmiljön bland annat genom huggningar för bränsle och utsläpp av tungmetaller. Ett av de områden i Sverige som är mest känt för sin metallhantering är Bergslagen. Idag är många gruvor nedlagda. READ MORE

  4. 23. Anthropogenic influence on new particle formation in the marine boundary layer atmosphere

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Vilhelm Berg Malmborg; [2014]
    Keywords : Climate change; Aerosols; Physics; Modelling; New particle formation; NPF; NanoMap; ADCHEM; Shipping emissions; Earth and Environmental Sciences; Physics and Astronomy;

    Abstract : The most important parameter for estimates of the anthropogenic induced climate change is the radiative forcing. In a comparison of the earth’s radiative budget in the year 2011 relative to 1750, the intergovernmental panel on climate change concludes that the largest uncertainty in the total radiative forcing derives from aerosol particles and their ability to modify cloud properties as cloud condensation nuclei (CCN).

  6. 25. Application of the ChlorOut concept in a waste wood fired CFB boiler

    University essay from SLU/Dept. of Energy and Technology

    Author : Mårten Carlberg; [2008]
    Keywords : superheater; corrosion; alkali; chlorides; ammonium; sulphate; chlorOut; IACM; potassium; KCl; bio fuels; sulphur;

    Abstract : Boilers converting from sulphur rich fossil fuels to alkali and chlorine rich bio fuels often experience an increased super heater corrosion. This is partly due to the increased formation of KCl during combustion of bio fuels. The problem could, for instance, be handled with a sulphur containing additive to the fuel or to the flue gases.
