  1. 11. Utvärdering av tandkräm för minskad tandkänslighet : En marknadsundersökning av CAPOSAL® Tandkräm

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Raisa Razwana; Blessing Ezeilo; [2023]
    Nyckelord :Medicinsk teknik;

    Sammanfattning : Hypersensitive teeth are a regular issue for many people. The ingredients in CAPOSAL® Toothpaste aim to strengthen tooth enamel and relieve sensitivity by mineralization. The effectiveness and functionality of CAPOSAL® Toothpaste have only been studied in controlled lab settings. LÄS MER

  3. 12. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Marie Björs; [2023]
    Nyckelord :Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Sammanfattning : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. LÄS MER

  4. 13. ARCTIC MYCORRHIZAL INTERACTIONS UNDER CLIMATE CHANGE

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Otto Minas; [2022-07-06]
    Nyckelord :Climate change; Arctic ecology; arbuscular mycorrhiza; graminoids; plant ecology; soil ecology; carbon cycle.;

    Sammanfattning : The Arctic is experiencing climate change at an extreme rate, affecting both the rates of plant growth and nutrient cycling. Due to the changes in temperature, but also in nutrient cycling, with increased nutrient mineralization and decreasing P:N ratio (phosphorus, P and nitrogen, N), the arbuscular mycorrhizal fungi (AM) that are prevalent in warmer soils have shown the potential to increase in the otherwise unfavorable Arctic environment.

  5. 14. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Tsai-wei Tang; [2022-01-26]
    Nyckelord :N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Sammanfattning : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. LÄS MER

  7. 15. Biochar from separated digestate and pig manure as soil amendment

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Lovisa Nissen; [2022]
    Nyckelord :separation; screw press; incubation study; CO2 emission; N mineralization;

    Sammanfattning : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. LÄS MER
