  1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    University essay from SLU/Dept. of Soil and Environment

    Author : Bella Strid; [2024]
    Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Abstract : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. READ MORE

  3. 2. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : David Trulsson; [2023]
    Keywords : Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

    Abstract : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. READ MORE

  4. 3. A top-down investigation of the possible extension of oxygen concentrator use within Swedish healthcare, with regards to national and global benefits

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Alice Lachmann; [2023]
    Keywords : oxygen concentrators; LOX; liquid oxygen; oxygen therapy; medical oxygen; oxygen cylinder; PSA; VPSA; oxygen supply; Technology and Engineering;

    Abstract : Oxygen concentrators are relatively small medical devices that concentrates oxygen from the ambient air next to the patient. They are widely used in low resource settings and in the home health care. READ MORE

  5. 4. Understanding the potential future capacity of distributing green steel solutions - current knowledge and future challenges

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Heba Alwan; [2023]
    Keywords : Carbon dioxide CO2 ; greenhouse gas GHG emissions; Steelmaking fossil-free; direct hydrogen reduction; Sustainability transitions.;

    Abstract : Transitioning from the conventional steel process to a direct hydrogen reduction process in the steel industry is a significant step towards reducing carbon dioxide emissions and achieving greater sustainability. The process involves using hydrogen gas as a reducing agent instead of carbon to remove oxygen from the iron ore. READ MORE

  6. 5. As I live and breathe! : The effects of hypolimnic oxygenation on benthic macroinvertebrate and zooplankton assemblages

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

    Author : Rashid Kadhim; [2022]
    Keywords : lake hypoxia; benthic macroinvertebrates; chironomids; zooplankton;

    Abstract : Exacerbated deep-water hypoxia, brought about by anthropogenic-derived dissolved organic carbon (DOC) input, has potentially detrimental impacts on organisms residing in freshwater ecosystems. Oxygenation of the water column is a potential management strategy to mitigate this impact, and used to alleviate DOC induced oxygen depletion. READ MORE
