  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. Assessment of Climate Change Impact on Rainfed Barley Production in the Mediterranean Basin : The Almeria province case study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Francesco Saretto; [2024]
    Nyckelord :Barley; Rainfed; Climate Change; AquaCrop; AquaCrop-OSPy; Mediterranean; Climate Change Adaptation; Crop Modeling; Agriculture; Irrigation;

    Sammanfattning : The Mediterranean basin is widely recognized as a climate change hotspot, with climate models projecting increasingly warmer and drier conditions that will impact local ecosystems, communities, and economies. Agriculture will be among the most affected sectors, with harsher conditions for crops’ growth, greater water needs, and lower yields. LÄS MER

  3. 3. Publikens förväntningar på dokumentärfilm : En studie om lärarstudenters inställning till och användning av dokumentärer

    Kandidat-uppsats, Högskolan Dalarna/Institutionen för kultur och samhälle

    Författare :Elin Johansson; Jeppe Schous; [2024]
    Nyckelord :Dokumentär; Publik; Lärarstudenter; Trovärdighet; Källkritik; Objektivitet; Subjektivitet; Dramatisering;

    Sammanfattning : There is a general perception amongst audiences of the documentary film being a truthful retelling of reality. The filmmaker is seen as a lens through which reality is captured in the way it presents itself to the filmmaker. LÄS MER

  4. 4. A Novel Method for Measuring Low Energy Excitations with BLS

    L3-uppsats, Uppsala universitet/Materialfysik

    Författare :Christopher Borchert; [2024]
    Nyckelord :;

    Sammanfattning : This report presents the work done on an optical setup combining Raman and BLS spectroscopy and discusses the achieved improvements of the system. After some general optimization and minor redesigning, a new alternative beam path was implemented. LÄS MER

  5. 5. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ellen Svens; [2024]
    Nyckelord :Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

    Sammanfattning : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.
