  1. 1. Skalningseffekter av medelstora pölbränder i syrereducerad miljö

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tim Hemel; Philip Frenander; [2024]
    Nyckelord :Sökord: syrereducerad atmosfär; medelstora pölbränder; skalningseffekter. Key words: hypoxic air; oxygen reduced atmosphere; medium pool fire; scaling effects; LOC; yields.; Technology and Engineering;

    Sammanfattning : This bachelor's thesis focuses on how scaling the pool diameter affects flammable liquids in an oxygen reduction system (ORS). This topic in the study of pool fire behavior in hypoxic air has been only lightly discussed in previous literature. Therefore, the goal of this thesis work is to further broaden the understanding of hypoxic air. LÄS MER

  3. 2. Decay Chains of Fast Alpha Emitters in the Actinide Region

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Tanvir Sayed; [2024]
    Nyckelord :alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

    Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER

  4. 3. Bränder i Elektrifierade Truckar

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Cecilia Östholm; [2024]
    Nyckelord :Litium-jon batteri bränder; Elektrifierade truckar; Förebyggande åtgärder; Åtgärder under brand; Litteraturstudie; Intervjustudie.; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to quantify the consequences of a fire in Kalmar Globals Heavy Electric Forklifts and Electric Reachstackers as well as what actions can be taken to reduce the effects of an ongoing fire and what preventing measures can be made by Kalmar Globals customers to create a safe environment and reduce the probability of a fire breaking out. This thesis builds on information gathered during a literature study and a complementary interview study. LÄS MER

  5. 4. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  7. 5. Petrological, geochemical and structural evidence of fluid-rock interaction in the Siljan Ring

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :William Crang; [2024]
    Nyckelord :methane; hydrothermal fluids; fluid-rock interaction; impact craters; reduction haloes; pyrite preservation; Siljan Ring;

    Sammanfattning : The Siljan Ring in Dalarna, Sweden is the site of the largest meteor impact crater in Europe and has long been a topic of discussion regarding methane production. However, the source of this methane and the timing of production in relation to the impact remain unclear. LÄS MER
