  1. 21. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Liliana Marcela Daza Gomez; [2023]
    Nyckelord :nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

    Sammanfattning : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. LÄS MER

  3. 22. Utveckling och utvärdering av en funktionssäker pulsgivare : Konkretisering och vidareutveckling av en patenterad lösning vilken ämnas detektera låsta lager

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Kim Bojnell; [2023]

    Sammanfattning : An emerging industrial automation has led to higher demands required for construction of encoders to ensure functionality of automated processes. The main purpose of the encoder is to provide data which indicates the condition of a drive system. LÄS MER

  4. 23. Under Pressure : The Effect of Negative Emotional States on Stress Coping

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Frida Larsson Torri; [2023]
    Nyckelord :stress coping; depression; anxiety; controllability;

    Sammanfattning : Individuals exhibit different reactions to stress, both between individuals and within individuals at different time points. A person’s current emotional state is one of the primary factors that influences how they handle a stressful situation. LÄS MER

  5. 24. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nikolaos Kouskoulis; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Sammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER

  7. 25. Relatedness and diversity in Swedish local chicken breeds using mitochondrial DNA D-loop sequences and SNP data

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Esther Taiwo Afolabi; [2023]
    Nyckelord :chicken; genetic diversity; mtDNA d-loop; SNP; Swedish local chicken breeds;

    Sammanfattning : Genetic diversity is the variation in genetic information carried by individuals within a species or population. This variability plays a crucial role in enabling species to adapt and survive in changing environments and is essential for evolutionary processes. LÄS MER
