  1. 11. The Baltic Sea marine system - human impact and natural variations

    Författare :Erik Gustafsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; modelling; salinity; oxygen; nutrients; eutrophication; acidification; climate;

    Sammanfattning : The environmental state of the Baltic Sea system is influenced by both natural and anthropogenic factors. Water exchange with the adjacent ocean and within the system depend on large-scale atmospheric circulation and properties of the straits separating the different sub-basins. LÄS MER

  3. 12. Influence of resuspension on sediment-water solute exchange and particle transport in marine environments

    Författare :Elin Almroth Rosell; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resuspension; benthic fluxes; oxygen; dissolved inorganic carbon; nutrients; dissolved iron and manganese; in situ chambers; benthic lander; organic matter transport; ecological modeling; Gothenburg Archipelago; Gulf of Finland; Baltic Sea; Loch Creran; Scotland;

    Sammanfattning : Marine sediments contain a large pool of nutrients, which if released would contribute to increased eutrophication, in spite of decreased nutrient loads from land and atmosphere. Resuspension is a process, which might influence the release of nutrients from the sediment to the overlying water. LÄS MER

  4. 13. Impact of Cultivation Parameters on Cell Physiology of Limosilactobacillus reuteri

    Författare :Nikhil Seshagiri Rao; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; probiotics; L. reuteri; oxygen; fermentation; heterogeneity; morphology; flow cytometery; freeze-drying; stress tolerance; Online flow cytometry; k-means clustering; fatty acids; defined minimal media; pre-formulation hold time;

    Sammanfattning : Optimisation of cultivation conditions in the industrial production of probiotics is crucial to reach a high-quality product with high probiotic functionality. The production process includes a fermentation step to produce biomass, accompanied by centrifugation to concentrate the cells. LÄS MER

  5. 14. Parental and embryonic behaviours in precocial birds

    Författare :Irene Persson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pheasants; growth rate; oxygen consumption; hatch synchronization; incubation behaviour; nest predation; physical condition; Egg laying; primary sex ratio; mallards; Animal ecology; Djurekologi;

    Sammanfattning : This thesis deals with behaviours during reproduction in precocial birds, both from the perspective of the female and of the embryos. Female pheasants in good physical condition laid larger eggs and produced a higher proportion of daughters than females in poor condition. LÄS MER

  7. 15. Cardiac surgery and the kidney - studies on the effects of pharmacological interventions on renal perfusion, filtration and oxygenation

    Författare :Gudrun Bragadottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute; glomerular filtration rate; renal circulation; oxygen consumption; cardiac surgery; vasopressin; mannitol; levosimendan; estimating equations;

    Sammanfattning : Acute kidney injury (AKI) commonly complicates cardiac surgery and is associated with high mortality. Renal ischemia is considered to be the major cause. There is a close association between glomerular filtration rate (GFR), tubular sodium reabsorption and renal oxygen consumption (RVO2) in humans. LÄS MER
