    Keywords : Chernobyl incident; Sweden; radio-cesium; contamination; terrestrial environment; quatic environment;

    Abstract : Technological advancement and the quest for power have gradually contaminated our environment, as industrialization, agriculture, and nuclear activities progressed. In the year 1986, a terrible nuclear incident occurred in Ukraine, in which the nuclear reactor exploded. READ MORE

  3. 12. Record of the end-Triassic mass extinction in shallow marine carbonates: the Lorüns section (Austria)

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linus Brakebusch; [2022]
    Keywords : sedimentology; geochemistry; ooids; oolites; oncoids; oncolites; Triassic; Jurassic; Rhaetian; Hettangian; ocean acidification; Earth and Environmental Sciences;

    Abstract : The end-Triassic mass extinction (ETE) was one of the five big mass extinctions of the Phanerozoic and occurred ~201 Ma ago. Research agrees that the main triggering factor for the ETE was the eruptions of the Central Atlantic Magmatic Volcanic Province (CAMP), linked to the break-up of the supercontinent Pangaea.

  4. 13. Assessment of Corrosion-Resistant Anodic Aluminium Oxide Coating

    University essay from Jönköping University/JTH. Forskningsmiljö Material och tillverkning - Ytteknik; Jönköping University/JTH, Konstruktion och produktutveckling

    Author : Mano Kannan Katturajan; Thamel WAP; [2022]
    Keywords : Aluminium; Anodic Oxide Coating; Corrosion; Corrosion Tests.;

    Abstract : The aim of this project is to investigate the quality of the anodic oxide coating of twotypes of aluminium alloy samples, EN AW-6014 and EN AC-43100, and to identifyappropriate test methods to assess their corrosion resistance properties. The corrosionbehaviors of the anodic oxide coating of the selected aluminium alloys with the surfacestage as-is, anodized, and anodized & scratched are evaluated through standardizedclimate chamber tests, standardized and non-standardized immersion tests, non-standardized climatic cycle tests, and electrochemical tests.

  5. 14. Fatigue and microstructural study of a 316L austenitic stainless steel marine component produced by Wire Arc Additive Manufacturing (WAAM)

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Oskar Bremler; [2022]
    Keywords : Fatigue; steel; 316L; waam; wire arc additive manufacturing; AM; additive manufacturing;

    Abstract : In this study, the fatigue- and fracture properties and microstructure of a marine component of austenitic stainless steel 316L manufactured with the novel method Wire Arc Additive Manufacturing were investigated and compared with data from literature. The purpose was to find a critical flaw size in the material related to its fatigue life. READ MORE

  6. 15. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
    Keywords : CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

    Abstract : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. READ MORE
