  4. 3. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

    Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Bubaraye Ohiosimuan Dirikumo; [2023]
    Nyckelord :Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

    Sammanfattning : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.

  5. 4. Quality enhancement of time-resolved computed tomography scans with cycleGAN

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Johannes Stubbe; [2023]
    Nyckelord :carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

    Sammanfattning : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. LÄS MER

  7. 5. Stock Splits' Impact on Liquidity Under Current Market Conditions

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Ludvig Völcker; Lowiza Svensson; [2023]
    Nyckelord :Splits; Liquidity; Signaling; Optimal trading range; Nasdaq Stockholm;

    Sammanfattning : This study examines whether stock splits still improve liquidity under current market conditions. To do so, we conduct three t-tests to examine changes in the bid-ask spread, turnover in relation to market capitalization, and Amivest Liquidity Ratio, around 64 share splits on Nasdaq Stockholm between 2013 and 2022, both for individual firms and on a general level.
