  1. 1. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Sofia Bjarheim; [2024]
    Keywords : Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

    Abstract : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. READ MORE

  3. 2. Uncertainty Estimation in Radiation Dose Prediction U-Net

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Frida Skarf; [2023]
    Keywords : Radiation dose prediction models; U-net; quantile regression; Monte Carlo Dropout; epistemic uncertainty estimation; aleatoric uncertainty estimation; Stråldospredicerande modeller; U-net; kvantilregression; Monte Carlo Dropout; epistemisk osäkerhetsskattning; aletorisk osäkerhetsskattning;

    Abstract : The ability to quantify uncertainties associated with neural network predictions is crucial when they are relied upon in decision-making processes, especially in safety-critical applications like radiation therapy. In this paper, a single-model estimator of both epistemic and aleatoric uncertainties in a regression 3D U-net used for radiation dose prediction is presented. READ MORE

  4. 3. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

    University essay from SLU/Dept. of Soil and Environment

    Author : Liliana Marcela Daza Gomez; [2023]
    Keywords : nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

    Abstract : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. READ MORE

  5. 4. Organized Crime and Government Trust under the Covid-19 pandemic. The case study of Sicily.

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Andrea Cavallo; [2023]
    Keywords : Sicilian Mafia; organized crime; government trust; Covid-19; vaccination campaign.; Social Sciences; Law and Political Science; Business and Economics;

    Abstract : Do municipalities in which organized crime is strongly established present lower Covid-19 vaccination rates, as a proxy for government trust? This paper aims to answer this question in the specific case of the Italian region of Sicily. Specifically, the analysis exploits a panel dataset of 390 Sicilian municipalities over 107 weeks (between the 27th of December 2020 and the 1st of January 2023) to study if areas with a higher presence of the Mafia, measured through historical sources and more recent data, negatively correlate with the cumulative weekly percentage of Covid-19 vaccinations per municipality.

  6. 5. Påverkar graden av insulindysreglering effekten av behandling med kanagliflozin hos hästar med ekvint metabolt syndrom?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Ida Ivarsson; [2023]
    Keywords : Ekvint metabolt syndrom EMS ; Insulindysreglering ID ; Hyperinsulinemi; Kanagliflozin;

    Abstract : Ekvint metabolt syndrom (EMS) kan förklaras som ett antal riskfaktorer som bidrar till utvecklingen av fång hos hästar. Insulindysreglering (ID) och obesitas med eller utan regional fettansättning utgör viktiga riskfaktorer som ingår i syndromet. Hästar med ID får onormalt höga insulinkoncentrationer i plasma, kallat hyperinsulinemi. READ MORE
