  1. 1. Tiaminbrist på idisslare : hur vanligt är det med symtom i Sverige?

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Johan Turnstedt; [2024]
    Nyckelord :CCN; cerebrocortikal nekros; PEM; polioencefalomalaci; enkätstudie;

    Sammanfattning : Tiamin är ett vattenlösligt vitamin essentiellt för många djur, inklusive människor. Idisslare producerar normalt tillräckligt med tiamin via mikrober i våmmen, men brist kan ändå uppstå vid särskilda förhållanden. LÄS MER

  3. 2. How do rainfall patterns change microbial induced carbon dynamics in soil?

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Maria João Silva; [2023]
    Nyckelord :drying and rewetting; bacterial growth; fungal growth; annual crops; perennial crops; soil depth; climate change; biotechnology; Biology and Life Sciences;

    Sammanfattning : Climate change is changing the precipitation patterns around the globe, leading to more extreme weather events like severe drought and heavy rainfalls. These events are intrinsically related to soil moisture fluctuations, which strongly modulates carbon fluxes in terrestrial ecosystems. LÄS MER

  4. 3. The Impact of Oat and Fruit Consumption on Short-Chain Fatty Acid Production

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

    Författare :Johanna Margaretha Schilder; [2023]
    Nyckelord :short-chain fatty acids; SCFAs; diet; gas chromatography; serum; mice; applied nutrition and food chemistry; Agriculture and Food Sciences;

    Sammanfattning : This study explored the importance of short-chain fatty acids (SCFAs) in maintaining gut health and how different diets affect their levels. Blood plasma and serum samples from mice subjected to two intervention studies on oats and fruits were analysed to determine SCFA concentrations. LÄS MER

  5. 4. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jonas Fahlman; [2023]
    Nyckelord :astrobiology; icy moons; subglacial lakes; ice dynamics; thermal regimes; extremophiles; anthropogenic contamination; astrobiologi; ismånar; subglaciala sjöar; is-dynamik; termiska regimer; extremofiler; antropologisk kontaminering;

    Sammanfattning : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

  7. 5. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Philippe Simon; [2023]
    Nyckelord :Ley production; Nitrogen fixation; Pollination ecology;

    Sammanfattning : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). LÄS MER
