  1. 11. Factors influencing interpersonal variability in plasma enterolactone concentration

    University essay from SLU/Dept. of Food Science

    Author : Elin Hålldin; [2016]
    Keywords : enterolactone; lignans; interpersonal variability; intestinal microflora; phytoestrogens; plasma;

    Abstract : Lignans are biologically active diphenolic plant compounds with potential health affecting properties. Some epidemiological studies have demonstrated that a high lignan intake is associated with risk reduction of several chronic diseases such as breast, prostate and colorectal cancer as well as cardiovascular disease.

  3. 12. Sources of organic carbon fueling carbon emissions from tropical reservoirs

    University essay from

    Author : Gabriella Villamor Saucedo; [2016]
    Keywords : tropical reservoirs; decomposition; autochthonous carbon; allochthonous carbon; tropical macrophytes; methanogenesis; tropiska vattenkraftsmagasin; metangasproduktion; autoktont OM; alloktont OM; tropiska makrofyter;

    Abstract : For a sustainable energy supply, it is of importance to be aware about the environmental impacts from the different energy sources. Hydroelectric reservoirs in tropical areas have been found to emit more greenhouse gases (GHG) than reservoirs from boreal regions. READ MORE

  4. 13. Spatial Variability of Greenhouse Gas Emissions from Tropical Reservoirs

    University essay from Uppsala universitet/Limnologi

    Author : David Rudberg; [2015]
    Keywords : diffusion; ebullition; tropical reservoirs; hydropower; greenhouse gas emission; diffusion; ebullition; tropiska vattenmagasin; vattenkraft; växthusgaser;

    Abstract : Hydroelectricity has for a long time been considered climate neutral due to it being a renewable source of energy. During the last years however, studies have shown that emission magnitudes from hydroelectric reservoirs may be equal to those of fossil fuel power plants. READ MORE

  5. 14. Spatial Variability in Greenhouse Gas Production in Sediments of a Tropical Reservoir

    University essay from Uppsala universitet/Limnologi

    Author : Stina K. Björkman; [2015]
    Keywords : CH4 production; C N-ratio; water content; carbon mineralisation; tropical reservoir; greenhouse gas emission;

    Abstract : The objective was to study the spatial variability of organic matter degradation in the sediments of a tropical reservoir to answer the hypothesis that degradation is significantly higher in river inflow areas than in other parts of the reservoir. Sediment cores were collected from twelve sites in the nutrient poor drinking water reservoir Chapéu d’Uvas in Minas Gerais, Brazil. READ MORE

  6. 15. Evaluation of modeling ecosystem seasonality in the University of Victoria Earth System Climate Model

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Annika Eisele; [2013]
    Keywords : Biology and Life Sciences;

    Abstract : Abstract Investigating climate model ability to simulate ecosystem seasonality, for instance causes and dynamics of phytoplankton blooms in the North Atlantic, is of major importance, because interannual and seasonal variations in bloom timing, duration and intensity caused by anthropogenic induced global climate change, can lead to species shifts and alterations in the trophic food web and biogeochemical cycles, which otherwise may remain undetected on an annual scale. The seasonal variability of the North Atlantic spring bloom is highly related to surface pCO2 (Takahashi et al. READ MORE
