  1. 21. How Do Long-Term Declines in Anthropogenic Sulfur Dioxide Emissions and Sulfate Wet Deposition Compare with Trends in Freshwater Chemistry in Scandinavian Rivers?

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Linnea Georgii; [2017]
    Keywords : sulfur dioxide; SO2; SO42-; river chemistry; Scandinavia; Sweden; Norway; svaveldioxid; SO2; SO42-; vattendrag; Skandinavien; Sverige; Norge;

    Abstract : Acidification of precipitation is an important environmental problem that emerged during the past century, especially after the Second World War. Acidification was primarily caused by human-made emissions of SOx (mostly SO2) and NOx, which are oxidized sulfur and nitrogen gases. READ MORE

  2. 22. Modelling of Metal Recovery using Sulfate Reducing Bacteria, Simulation in MATLAB and Aspen Plus

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Hanna Kvarnström; Erika Lönntoft; [2017]
    Keywords : Sulfate reducing bacteria; Metal sulfides; Metal Recovery; Metal precipitation; Modelling; Simulation; Aspen Plus; Matlab; Technology and Engineering;

    Abstract : This report presents a mathematical kinetic model describing the recovery of metal ions as metal sulfides, using sulfate reducing bacteria (SRB). Metal recovery from industrial waste is a potential beneficial and unused source of metals. READ MORE

  3. 23. Två-fas extraktion av polyfenoler från blåbär

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Simon Vikström; [2017]
    Keywords : blåbär; polyfenol; antocyanin; två-fas extration; RBR; natriumfosfat; ammoniumsulfat;

    Abstract : I de svenska skogarna produceras det varje år ca 250 000 ton blåbär och av det tillvaratas endast ca 7 %. Blåbär innehåller höga halter av antocyanin vilket är väldigt attraktivt på hälsokostmarknaden. READ MORE

  4. 24. Geochemical processes in mine waste subjected to a changing chemical environment: Fe speciation in leachate water from column experiments

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Paula Lundberg; [2017]
    Keywords : Sulfidic mine waste; Sulfide oxidation; Water quality; Environmental analytical chemistry; Iron redox speciation;

    Abstract : Oxidation of sulfidic mine waste is of significant environmental concern due to the consequent formation of acid rock drainage (ARD), deteriorating the water quality of natural water systems. Iron (Fe) and sulfur (S) are two major redox elements involved in these reactions and typically the major redox-sensitive elements (whose solubility, speciation, and mobility are affected by pH and Eh) in water affected by ARD.

  5. 25. Glukosamin - är det effektivt till hundar med osteoartrit?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Tilde Bromée; [2016]
    Keywords : Osteoartrit; glukosamin; hund; behandling; foder; kosttillskott; biotillgänglighet; Osteoarthritis; glucosamine; dog; canine; treatment; dogfood; nutraceutical;

    Abstract : Osteoartrit (OA) är en av de vanligaste kroniska muskuloskeletala sjukdomarna och orsakerna till hälta hos hund. Inget botemedel finns utan behandlingen syftar till att minska symtomen och förhindra ytterligare leddestruktion. Icke-steroida anti-inflammatoriska medel (NSAID) är ett vanligt behandlingsalternativ vid OA. READ MORE
