  1. 1. Decay Chains of Fast Alpha Emitters in the Actinide Region

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Tanvir Sayed; [2024]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Förekomst av snöskytte i hyggesfria metoden schackrutehuggning i Västerbotten

    University essay from SLU/School for Forest Management

    Author : Jenny Johansson; [2024]
    Keywords : phacidium infestans; kontinuitetsskogsbruk; Norrland;

    Abstract : Skogen är och har länge varit en viktig resurs för länet Västerbotten och den står för cirka 14 procent av den produktiva skogsmarksarealen i Sverige. Skogen i Västerbotten har brukats sedan medeltiden från småskaligt hushållsbehov till storskaligt skogsbruk i modern tid. READ MORE

  4. 3. A parasitic bivalve affects the interaction between a native and an invasive salmonid

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Brander Isac; [2023-04-18]
    Keywords : Glochidia larvae; Infestation class; General dominance behavior; Dominant subordinate; Strikes;

    Abstract : The glochidia larvae of the freshwater pear mussel parasitize on juvenile brown trout during their maturation into tiny mussels. The parasitation has several negative impacts on the trout, one of the less studied being behavioral effects. READ MORE

  5. 4. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ivan Krsic; [2023]
    Keywords : HEMT; GaN; off-state stress; memory effects; drain leakage current; dynamic RDSon; threshold voltage instabilities; charge redistribution; HEMT; GaN; stress i avslaget tillstånd; minneseffekter; läckströmmen; dynamisk RDSon; instabiliteten hos styrets tröskelspänning; omfördelningen av laddningar;

    Abstract : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. READ MORE

  6. 5. BSF-colony management efficiency at a large scale fly larvae composting company in Kenya – A field study

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hilda Anderberg; [2023]
    Keywords : Black soldier fly composting; BSF-colony; industrial scale; parasitic wasps; Amerikansk vapenfluga; fluglarvskompostering; storskaligt; parasitsteklar;

    Abstract : The majority of organic waste globally is either dumped or placed on landfills, which can result in spreading of disease and pests, methane gas emissions, the deterioration of landscapes and odour pollution. One of the solutions to poor organic waste management is to create value from waste. READ MORE
