  1. 11. Experimental removal of anoxic hypolimnion conditions in a lake increases perch growth

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Felix Torsson; [2021]
    Keywords : Eurasian perch; oxygen limitation; individual condition; growth and stomach fullness.;

    Abstract : Global warming leads to an increased browning of lakes across the northern hemisphere. This browning can due to benthic light-limitation cause hypoxic bottom conditions which can have negative impact on the fish production in the northern lakes. READ MORE

  3. 12. Burning material behaviour in hypoxic environments: An experimental study examining fire dynamics of composite materials in vitiated conditions

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Robert Bray; [2020]
    Keywords : ORS; Fire engineering; hypoxic; polymers; Technology and Engineering;

    Abstract : The progression of fire safety research has contributed to improving the guiding principles of standardised building design. Research making use of pure materials, once common in homes and workplaces, are less relevant as such materials are no longer as prevalent. READ MORE

  4. 13. Site Study of Fibrous Sediments in Sandviken, Ångermanälven River Estuary, Sweden

    University essay from Uppsala universitet/Naturresurser och hållbar utveckling

    Author : Joanna Ghaderidosst; [2020]
    Keywords : Fiberbank; fiber-rich; fibrous sediment; pulp and paper industry; bearing capacity; FluMu; Penetrometer; Pollution; consolidation; gas; Fiberbank; fiberrik; fiberhaltigt sediment; pappersindustri; bärkraft; FluMu; penetrometer; förorening; gas;

    Abstract : Pulp and paper industries in Sweden have since the end of the 19th century until late 70s been active in dumping wastewater into adjacent water bodies that have created fibrous sediments called fiberbank and fiber-rich sediment. Fiberbanks are large banks of predominantly organic material while fiber-rich sediment is fibrous sediment that has been mixed with bottom sediment. READ MORE

  5. 14. Spatiotemporal responses of wheat and pea roots to fluctuations in soil physical conditions

    University essay from SLU/Dept. of Soil and Environment

    Author : Hanna Sjulgård; [2020]
    Keywords : rhizobox; time-lapse imaging; growth rate; diameter;

    Abstract : Penetration resistance and the oxygen level vary in the soil, and a root will face fluctuations in these physical properties during development. The aim of this study was to understand how pea (Pisum sativum L.) and wheat (Triticum aestivum L. READ MORE

  6. 15. Gas Emissions from Contaminated Fibrous Sediments in Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Collin; [2020]
    Keywords : Fiberbank; fibrous sediment; gas ebullition; GHG emissions; methanogenesis; optical ebullition sensor; Fiberbank; fibersediment; gas ebullition; växthusgas emissioner; metanogenes; optiska ebullitions sensore;

    Abstract : Gas Emissions from Contaminated Fibrous Sediments in Sweden The discharge of untreated wastewater from pulp and paper mills have resulted in the accumulation offibrous sediments on the bottom of many nearby aquatic recipients. Some accumulations are multiplemeters thick and consist almost entirely of cellulose fibre or wood chips; these are called fiberbanks. READ MORE
