  1. 16. Investigation of plasma cleaning on molybdenum crystals for diagnostic mirrors in fusion devices

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

    Author : Hafssa Laabadi; [2023]
    Keywords : ;

    Abstract : In the long-term energy scenario, nuclear fusion is a promising low-carbon and sustainable energy source. The unavoidable exposure of the wall materials to the plasma is a big challenge in realizing a fusion reactor. The plasma-facing components (PFCs) in the reactor wall will experience erosion deposition in the surface materials. READ MORE

  3. 17. Identification of Human Mesenchymal Stromal Cells and Culturing Media Effects on Proliferation, Differentiation, and Cell Surface Markers

    University essay from Uppsala universitet/Institutionen för medicinsk cellbiologi

    Author : Alice Törne; [2023]
    Keywords : MSC Characterization; Differentiation; Flowcytometry; Culturing media; T24;

    Abstract : The mesenchymal stromal cell (MSC) is of great interest for its immunomodulatory and regenerative properties. However, to research and use these MSCs it is essential to identify and characterize them as such. They need to fulfill the MSCs' minimal criteria which assess the differentiation potential, cell surface markers, and adherence. READ MORE

  4. 18. Petrography of impactites from the Dellen impact structure, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robert Mroczek; [2023]
    Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  5. 19. Characterization of Landscape Structures and Precipitation in relation to Flooding events in Pampa Deprimida : A Minor Field Study in Argentina

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Linnea Svärd; [2023]
    Keywords : Pampeana hydrology; flood risk mapping; runoff; infiltration; precipitation; SCSCN; remote sensingg; Hydrologi på Pampas; kartläggning av översvämningsrisker; avrinning; infiltration; nederbörd; SCS-CN; fjärranalys; Hidrología de la Pampa Deprimida; cartografía del riesgo de inundaciones; escorrentía; infiltración; precipitación; SCS-CN; sensores remotos;

    Abstract : The purpose of the thesis is to characterize flood events within the agricultural fields of flooding Pampa in Argentina. The characterization divides the flat landscape into flood prone areas and endeavour at linking driving factors to flood response based on past events. READ MORE

  6. 20. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Belén Alonso Rancurel; [2023]
    Keywords : austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

    Abstract : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.
