  1. 11. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför Lund

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Erik Borgström; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER

  3. 12. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Linnea Sjökvist; [2023]
    Nyckelord :Membrane filtration; ultrafiltration; PHA; polyhydroxyalkanoates; chemical engineering; Technology and Engineering;

    Sammanfattning : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. LÄS MER

  4. 13. Bacteria in the vagina during the estrous cycle in mares

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Timjan Åkerholm; [2023]
    Nyckelord :artificial insemination; bacteriology; breeding; embryo transfer; equine reproduction; estrous cycle; ovulation; stud farm; vagina;

    Sammanfattning : An understanding of the normal bacterial flora of any organ is essential to provide the background to conditions and interventions that might cause the flora to change. In the vagina of the mare, a change of bacterial flora could be induced by introduction of semen, treatment with antibiotics, backflow from an unhealthy uterus etc. LÄS MER

  5. 14. Understanding the effects of TCP-25 and EDTA interaction : A study of the biophysical aspects of a naturally derived peptide formulation with EDTA for topical application

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

    Författare :Ebba Kant; [2023]
    Nyckelord :chronic wounds; EDTA; biophysical aspects; formulation; pharmaceutical technology; Thrombin derived C-terminal peptide; Technology and Engineering;

    Sammanfattning : Chronic wounds are an emerging healthcare issue and current methods of healing chronic wounds address bacteria but are ineffective against resistant bacteria and the biofilm formation commonly observed in these wounds. Antimicrobial peptides (AMPs) derived from the endogenous wound healing system have been shown to combat bacterial infections, exhibit immunomodulatory effects, as well as improving wound healing.

  7. 15. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning

    Kandidat-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Johanna Forss; [2023]
    Nyckelord :etablering; kväve; skördesystem; Trifolium repens; vall; vitklöver;

    Sammanfattning : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. LÄS MER
