    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

  3. 2. Guds rike i Trankebar : pietistisk konfessionskultur under Trankebarmissionens första år: 1706-1714

    Författare :Anton Hagen; [2023]
    Nyckelord :mission; Trankebar; Indien; pietism; konfessionskultur; konfession; milleniarism; konversion; återfödelse; Hallesche Berichte; History and Archaeology;

    Sammanfattning : God’s Kingdom in Tranquebar : pietist Confessional Culture during the Establishing Years of the Danish-Halle Mission: 1706-1714. The aim of this thesis is to study and describe the confessional culture as displayed by the missionaries Bartholomäus Ziegenbalg (1682-1719) and Ernst Gründler (1677-1720) during the establishing years of the Pietist Danish-Halle Mission in the Danish colony of Tranquebar in south-east India.

  4. 3. Omforma mottagning för förpackningsavfall på Stockholms återvinningscentraler

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tilda Byrstedt; Zahra Almayahi; [2023]
    Nyckelord :;

    Sammanfattning : Regeringen har beslutat att ansvaret för insamling av förpackningsavfall ska tillhöra Sveriges kommuner. Idag har främst Förpacknings- och Tidningsinsamlingen (FTI) skött insamlingen av förpacknigsavfallet i hela Sverige. LÄS MER

  5. 4. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Elsa Muller; [2023]
    Nyckelord :Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

    Sammanfattning : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. LÄS MER

  7. 5. CFD Analysis of the Flow Around a Paraglider Wing

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Caterina Gennari; [2023]
    Nyckelord :Paraglider Wing; CFD; RANS; DES; Aerodynamics; Aerodynamic Hysteresis; FSI; Deformable Structure; Membrane; Shell Elements;

    Sammanfattning : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. LÄS MER
