  1. 16. Protein digestibility of biorefined juice from fresh and ensiled ley crops in growing pigs

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Jhon William Perez Davila; [2023]
    Nyckelord :protein digestibility; amino acids; ley crops; silage; biorefinery; press juice; growing pigs;

    Sammanfattning : The study aimed to evaluate the protein and amino acid digestibility of press juice from biorefined ley crops in the form of fresh (FPJ) and silage (SPJ) when included as an ingredient in liquid diets for pigs. The juice was extruded from ley crops mixture (grass-clover). LÄS MER

  3. 17. Development of thick GaN and AlGaN drift layers for vertical power devices

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Andri Dhora; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical application present a challenge.

  4. 18. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
    Nyckelord :hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

    Sammanfattning : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. LÄS MER

  5. 19. 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. 20. 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
