  1. 1. Impact of Residual Stress on the Warm Pre-Stressing Effect

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Emil Danielsson; [2023]
    Nyckelord :Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

    Sammanfattning : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. LÄS MER

  3. 2. The effect of mine closures on depopulation in the Principality of Asturias, Spain

    Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Cristina Álvarez Argüelles; [2023]
    Nyckelord :Social Sciences;

    Sammanfattning : The paper examines the impact of the mining sector's closure on population decline patterns in the Principality of Asturias, Spain. It utilizes two distinct databases of own construction that provide disaggregated data on the region's 78 councils. LÄS MER

  4. 3. The connection between the bow shock at Mercury and the interplanetary magnetic field

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Erik Sellberg; [2023]
    Nyckelord :Mercury bow shock; Bow shock - interplanetary magnetic field interaction; MESSENGER; Merkurius bogchock; Växelverkan bogchock interplanetära magnetfältet; MESSENGER;

    Sammanfattning : As the solar wind reaches Mercury it interacts with the planet’s magnetic field slowing down, forming a bow shock in front of the planet and diverting the flow around it. Along with the solar wind comes the interplanetary magnetic field, an extension of the sun’s magnetic field. LÄS MER

  5. 4. Moon plasma environment and its implications for lunar space missions

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Mirko Viviano; [2023]
    Nyckelord :;

    Sammanfattning : This study investigates the lunar plasma environment and its implications for the safety and success of future crewed missions to the Moon. The Moon’splasma environment, formed by the solar wind, galactic cosmic rays and solar flare particles, presents potential hazards to human life and property. LÄS MER

  7. 5. Computational Pipeline for Analyses of Genome-Wide Nascent Transcription from PRO-seq Data

    Master-uppsats, KTH/Genteknologi

    Författare :Serhat Aktay; [2023]
    Nyckelord :Transcription; functional genomic regions; heat shock response; computational pipeline development; automation.; Genavläsning; genomets funktionella regioner; värmechockrespons; dataanalysutveckling; automatisering;

    Sammanfattning : Celler har en rad olika sätt att försvara sig mot stress för att överleva, främst genom att reglera transkriptionen av gener. En metod för att undersöka hur cellens transkription förändras vid cellulär stress är precision run-on sequencing (PRO-seq). LÄS MER
