  1. 1. 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

  2. 2. Trilingual spoken word recognition : Interlingual competition from one or two non-target languages in a sentence context

    Magister-uppsats, Stockholms universitet/Centrum för tvåspråkighetsforskning

    Författare :Yulia Kashevarova; [2023]
    Nyckelord :trilingual speech processing; cross-linguistic competition; sentence context; BLINCS; BIA ;

    Sammanfattning : Persistent non-target language co-activation in spoken and visual language comprehension has been found both at the word-level and at the level of a sentence, although in the latter case, sentence bias has been observed to modulate the co-activation which can create lexical competition. In the case of trilingual speakers, both non-target languages may potentially compete with the third language (L3). LÄS MER

  3. 3. Fungal pigmentation responses to microclimatic variables in isolated forest patches in Northern Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Karl Soler Kinnerbäck; [2023]
    Nyckelord :fungal ecology; mycology; functional traits; communities; pigmentation; CIELAB; lightness; microclimate; polypores;

    Sammanfattning : Investigating functional traits is an important tool for understanding fungal communities, yet ecological functions of fungal pigmentation remain poorly investigated. Recent studies support the thermal-melanism hypothesis for fungal color lightness in relation to macroclimate, but it remains unclear if microclimate also affects fungal pigmentation. LÄS MER

  4. 4. Skillnader i artrikedom hos vedlevande mossor och lavar och substratkvalité mellan Säby Västerskogs naturreservat och en närliggande produktionsskog.

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Adrian Gren; [2022]
    Nyckelord :Moss; Lichen; Saproxylic; Biodiversity; Forestry; Species diversity; Loss; Comparison; Mossa; Lav; Vedlevande; Biologisk mångfald; Artrikedom; Skogsbruk; Förlust; Jämförelse;

    Sammanfattning : Den globala biologiska mångfalden minskar på grund av kraftig mänsklig exploatering av resurser. Ett sådant exempel är diversitetens nedgång i Fennoskandias skogar. LÄS MER

  5. 5. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Josephine Lindsey-Clark; [2021]
    Nyckelord :Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

    Sammanfattning : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation. LÄS MER
