  1. 16. Utfodring med ensilage till slaktgris : effekter på köttkvalitet och fettsyrasammansättning

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Erika Ohlsson; [2022]
    Keywords : köttkvalitet; fettsyrasammansättning; slaktgris; ensilage; vallfoder; proteinfodermedel;

    Abstract : Ensilage är en potentiell proteinkälla till gris då vallens aminosyraprofil passar grisens behov bra. I Sverige är förutsättningarna för vallodling goda och vallen har positiv inverkan på odlingsmarken. Vallen kan även skapa ett mervärde då den har positiva effekter på grisens välfärd samt är lokalt odlad. READ MORE

  3. 17. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

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

    Author : Frederika Klaus; [2022]
    Keywords : Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

    Abstract : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. READ MORE

  4. 18. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : William Stefansson; [2022]
    Keywords : PFAS; Aeration foam fractionation; Nanofiltration membrane; DWTP; Surfactant; PFAS; Skumfraktionering; Nanofiltration; Vattenverk; Surfaktant;

    Abstract : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. READ MORE

  5. 19. Peatland restoration: A mossy affair? : The similarities of the vegetation communitiesbetween restored bogs and natural bogs.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Liesbeth van Ravenhorst; [2022]
    Keywords : Wetland; peatland; bog; vegetation composition; plant functional trait; environmental variable;

    Abstract : Peatlands function as important global carbon sinks as peatlands store 30% to 40% of the total soil carbon even though peatlands only cover 3% of the Earth's terrestrial surface. However, drainage activities have damaged the ecosystem and caused many peatlands to function as carbon sources instead. READ MORE

  6. 20. Evaluation of pollutant removal performance of stormwater biofilters in a Swedish climate : Comparison of three different filter media designs

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anna Träff; [2022]
    Keywords : Stormwater biofilter; stormwater treatment; cold climate; filter media design; low impact development;

    Abstract : In the recent century, a process of urbanization has increased globally. Previously rural or natural land have been converted into impervious surfaces to make way for housing, industries, and roads. This anthropogenic process has resulted in an increased amount of surface runoff from precipitation, so-called stormwater. READ MORE
