    Sammanfattning : The lack of proper wastewater treatment inhibits the social and economic development in many communities. The South African town Wakkerstroom is an example where wastewater is first treated before it is released. LÄS MER

  3. 17. Is it possible to define different process domains in stream systems based on remote data? : Comparing surficial geology, geomorphological characteristics in the landscape and channel slope between lakes, rapids and slow-flowing reaches.

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Elin Åberg; [2019]
    Nyckelord :Process domains; Lakes; Slow-flowing reaches; Rapids; GIS; Slope; Surficial geology; Geomorphological characteristics in the landscape;

    Sammanfattning : Restoration of stream channels have become a common way of trying to restore both the channels and the ecosystems that earlier have been channelized mainly to facilitate the movement of timber. According to previous studies a lot of the restoration has been performed without a sufficiently detailed plan and with too little focus on how the landscape interplay with the restoration, which makes the potential to learn from possible mistakes minimal.

  4. 18. Analyzing microplastics in soils : Evaluating canola oil extractions

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anna Bottone; [2019]
    Nyckelord :Microplastics; extraction recovery; OEP method; organic-rich soils;

    Sammanfattning : Small fragments of artificial polymers (microplastics, MPs) has been reported for multiple environmental matrices from our planet. The omnipresent existence of these microplastics even in remote polar areas have raised concern about their potential environmental impacts and created a need for effective and standardized analytical methods targeting their detection in environmental samples.

  5. 19. MAGNETIC CHARACTERIZATION OF SELF-ASSEMBLED ONE-DIMENSIONAL NETWORKS OF MAGNETIC NANOPARTICLES

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Mario Salvador López Muñoz; [2019]
    Nyckelord :Nanomagnetism; Stoner-Wohlfarth; Magnetite Fe3O4; nanoparticles; Magnetic Characterization; Spark Discharge Technique; Physics and Astronomy;

    Sammanfattning : In this thesis, a magnetic study of two dierent arrangements of Fe3O4 nanoparticles is presented. The nanoparticles are generated using an aerosol technique and guided onto a substrate. LÄS MER

  7. 20. Fjällbjörkmätarlarvers påverkan på fjällbjörkskog : en fjärranalysstudie om markvegetationsförhållanden i subalpin miljö

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

    Sammanfattning : Since the mid-1950s, studies have frequently been conducted on couplings between geometrid moth outbreaks and mountain birch, though not nearly as much focus has been on connections between geometrid moth outbreaks and ground cover. Previous studies have shown that major outbreaks of Epirrita autumnata occur in 9 – 10-year cycles (Karlsson et al. LÄS MER
