  1. 1. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Emma Dahlstedt; [2023-08-18]
    Nyckelord :Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

    Sammanfattning : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. LÄS MER

  3. 2. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

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

    Författare :Linnéa Eriksson; [2023-04-20]
    Nyckelord :soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Sammanfattning : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. LÄS MER

  4. 3. Biogasproduktion vid samrötning av substrat tillgängliga vid lantbruk : Småskalig rötning vid Lillerudsgymnasiet

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Cecilia Svensson; [2023]
    Nyckelord :Biogas; agriculture;

    Sammanfattning : The world is currently heavily dependent on fossil sources and the use of fossil fuels leads to increased global warming. One of the solutions to this environmental problems is biogas. LÄS MER

  5. 4. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Karnsinee Viriyayudhakorn; [2023]
    Nyckelord :human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. LÄS MER

  7. 5. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Yixian Chen; [2023]
    Nyckelord :density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Sammanfattning : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. LÄS MER
