  1. 1. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Pascal Camoiras González; [2019]
    Nyckelord :;

    Sammanfattning : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).

  2. 2. Sustainable Drainage Systems Assessment and Optimisation-A case study for Lussebäcken Catchment, Helsingborg

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Bernard Nsabimana; Néstor Utande Estallo; [2019]
    Nyckelord :Hydraulics; hydrology; Sustainable Drainage Systems; urban; Modeling; MIKE URBAN; Technology and Engineering;

    Sammanfattning : Increase of urbanization and climate change are one of the factors that have been highlighted to influence hydrography. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding and increased pollution are the problems that arises. LÄS MER

  3. 3. Snow insulation effects across the Arctic : evaluating a revised snow module in LPJ-GUESS

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Alexandra Pongrácz; [2019]
    Nyckelord :active layer depth; Arctic; LPJ-GUESS; snow; soil temperature; Earth and Environmental Sciences;

    Sammanfattning : The effect of future changes in temperature and precipitation patterns on arctic ecosystem functioning is often assessed using state-of-the-art ecosystem models. Many models however lack detailed representation of wintertime processes, as pointed out by recent studies (Wang et al. 2016, Slater and Lawrence 2013). LÄS MER

  4. 4. Plant functional diversity across a spatial climate gradient in Sweden

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Nina Lončarević; [2019]
    Nyckelord :landscape ecology; plant functional ecology;

    Sammanfattning : Introduction. Climate is a well-known and well-studied abiotic driver of the natural world working through e.g. physiological alterations in species, changes in species’ ranges and growing season, reduction in growth or causing mortality. LÄS MER

  5. 5. Framtidsutsikter för pastoralism på Kenyanska betesmarker

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Zebastian Cederblad; [2019]
    Nyckelord :Kenya; ; kenyanska betesmarker; pastoralism; zebu; boskap; landfragmentering; klimatförändringar;

    Sammanfattning : Pastoralism är ett system där majoriteten av en individs inkomst och mat kommer från boskapsdjur. Boskapsdjurens huvudsakliga matkälla är naturligt växande bete. Pastoralism kan delas in i tre huvudtyper; nomadisk, transhuman och stillasittande. I Kenya finns variationer av alla tre. LÄS MER
