  1. 1. "Gropen dom har grävt åt oss fem-femmor" : En fallstudie av 15 brevskrivande patienter vid S:t Sigfrids kriminalavdelning under åren 1948–1952

    Uppsats för yrkesexamina på avancerad nivå, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Författare :Kevin Lif Grönholm; [2024]
    Nyckelord :S:t Sigfrids sjukhus; straffriförklarade; motmakt; vård; straff;

    Sammanfattning : This study aimed to answer three main questions: (1) How are the 15 patients at St. Sigfrid’s criminal ward described in the documentation during the years 1948-1952; (2) How can these descriptions be contrasted with the image of the patients through their own words and actions, considering factors such as a) power relations including various forms of resistance and b) the balance between care and punishment; and (3) How can the study be made relevant and utilized within the framework of the objectives of history and psychology according to the curriculum? To answer these questions a text analysis was conducted where the patients’ documentation and letters were read, interpreted, and summarized. LÄS MER

  3. 2. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  4. 3. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

    Master-uppsats, KTH/Materialvetenskap

    Författare :Felicia Larsson; [2023]
    Nyckelord :;

    Sammanfattning : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. LÄS MER

  5. 4. Numerical Simulations of Resonant Tunnelling Diodes

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Love Sundström; Alexander Holmström Janeld; [2023]
    Nyckelord :Quantum mechanics; numerical methods; resonant tunnelling diode;

    Sammanfattning : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

  7. 5. We Are the Solution: Seed Sovereignty, Local Knowledge Systems and Women’s Liberation Through Rice Farming in Southern Senegal

    Master-uppsats, Lunds universitet/Kulturgeografi och ekonomisk geografi; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

    Författare :Na Haby Stella Faye; [2023]
    Nyckelord :Social Sciences;

    Sammanfattning : The system of capitalist agriculture increasingly shows its social, economic and ecological failures. Some of the alternatives are based on food and seed sovereignty. However, the knowledge systems underlying seed saving practices, especially in the West African context, have been overlooked. LÄS MER
