  1. 6. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Andersson; [2021]
    Keywords : geochemistry; loess; XRF; weathering; climate change; N-W France;

    Abstract : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. READ MORE

  3. 7. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Pelle Kronborg; [2020]
    Keywords : loess; XRF; weathering index; England; Lowland Point; Porth Cressa; Quaternary; löss; XRF; vittrings index; kvartär; England; Lowland Point; Porth Cressa;

    Abstract : Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. READ MORE

  4. 8. How robust is water quality determination with optical measurements for highly polluted agricultural waters?

    University essay from SLU/Dept. of Soil and Environment

    Author : Honorine Uwera; [2020]
    Keywords : turbidity; suspended sediments; dissolved organic matter; optical measurements;

    Abstract : Optical technology is used to measure and monitor water quality, to date mainly in drinking water treatment, where water is typically much cleaner than in heavily polluted agricultural streams. To characterize suspended sediments (SS) and dissolved organic matter (DOM) in surface water some optical measurements have been used (absorbance and fluorescence spectroscopy). READ MORE

  5. 9. New methods for seed potato production: an investigation into the production and farmer uptake of mini tubers in South Africa

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Alba Sáez Fernández; [2018]
    Keywords : mini-tubers; Chlorophyll fluorescence; Leaf Area Index; small-scale farming;

    Abstract : Potatoes are by far the most produced fresh vegetable crop in South Africa. Remarkably, potato sales represent more than 30% of the turnover in the Fresh Produce Markets (FPM). READ MORE

  6. 10. Dissolved organic matter (DOM) quality in agricultural streams and its impact on carbon dioxide concentrations in stream water

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Broqvist; [2018]
    Keywords : DOM quality; dissolved organic matter; DOC; PARAFAC; fluorescence; streams; agriculture; fluorescence index; freshness index; humification index; carbon dioxide; DOM kvalitet; löst organiskt material; DOC; PARAFAC; fluorescens; bäckar; jordbruk; fluorescence index; freshness index; humification index; koldioxid;

    Abstract : Inland waters have lately been recognized to be an important component in the carbon cycle, having a significant role in carbon sequestration and carbon dioxide (CO2) emissions. Attention has also been drawn to the impact of the quality (i.e. composition and source) of dissolved organic matter (DOM) on CO2 production. READ MORE
