  1. 1. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation

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

    Författare :Maja Holm; [2024]
    Nyckelord :Physical geography; ecosystem science; soil organic carbon; soil sampling; perennial crops; carbon sequestration; carbon farming; Kernza™; soil organic carbon stock; Earth and Environmental Sciences;

    Sammanfattning : Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. LÄS MER

  3. 2. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

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

    Författare :Fanny Otterlin Karlsson; [2024]
    Nyckelord :agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Sammanfattning : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. LÄS MER

  4. 3. 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. 4. Brunifiering av akvatiska ekosystem: En experimentell studie som undersöker tröskelvärde för predator- och bytesförhållande vid en gradient från klart till brunt vatten

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Erik Nilsson; [2023]
    Nyckelord :Brunifiering; tröskelvärde; födointag; predator- och bytesförhållande; Earth and Environmental Sciences;

    Sammanfattning : Browning of water has increased over the last couple of decades on the northern hemisphere. Research show that possible drivers for this change are land use change, climate change, increased precipitation and increased temperatures. LÄS MER

  7. 5. Phase Change Material : Potential for increased fire resistance in concrete

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :William Toivanen; [2023]
    Nyckelord :Phase change material; concrete; fire resistance; integration into building materials; latent heat; melting;

    Sammanfattning : The European commission has in the Energy Performance of Buildings Directive from 2010 decided that its member states were required to ensure that all new buildings by the end of 2020 were nearly zero-energy buildings. These buildings require small amounts of energy compared to its performance in example by keeping a pleasant indoor climate. LÄS MER
