    University essay from KTH/Fysik

    Author : Maria Giamouridou; [2023]
    Keywords : uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

    Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

  2. 2. The Fe-oxides (mineralogical, chemical, and textural) variation in the Leveäniemi deposit using micro-analytical tools for unraveling of primary features and metamorphic recrystallisation

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Adrian Larsson; [2022]
    Keywords : Leveäniemi; Magnetite; Hematite; Iron oxides; Iron oxide apatite;

    Abstract : The Leveäniemi iron oxide apatite (IOA) deposit, mined by LKAB, is located in Norrbotten, northern Sweden. The deposit has a partially more complex mineralogy than the neighbouring and more famous IOA deposits of Kiirunavaara and Malmberget. READ MORE

  3. 3. Classification of four mesosiderites and implications for their formation

    University essay from Lunds universitet/Geologiska institutionen

    Author : Gabriel Zachén; [2020]
    Keywords : mesosiderites; meteorites; stony-irons; classification; textures shock; emulsion; melt droplet; Lamont Acfer 265; QUE 86900; MAC 88102; Earth and Environmental Sciences;

    Abstract : Mesosiderites are rare stony-iron meteorites with enigmatic origins. Their unusual mix of crustal and core materials have inspired many formation theories over the last century. READ MORE

  4. 4. Modelling cross-laminated timber floors in dynamic analysis - Eigenfrequency prediction

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Johannes Wetterholt; [2019]
    Keywords : finite element method; FEM; dynamic analysis; Eigenfrequency; CLT; cross-laminated timber; cross-laminated timber floors; wooden floors; Technology and Engineering;

    Abstract : In the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials.

  5. 5. Fång hos häst och dess association till grovtarmsstörningar

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Julia Strandberg; [2018]
    Keywords : aminer; bete; endotoxiner; exotoxiner; icke-strukturella kolhydrater; inflammatoriska cytokiner; kolhydrater; lameller; matrix metalloproteinaser; fruktaner; spannmål; stärkelse; vallfoder;

    Abstract : Fång är ett systemiskt tillstånd som uppenbarar sig i hoven och innebär en inflammation av hovens lameller. Vid fång kommer förbindelsen mellan hovbenet och hovväggen att upphöra och den drabbade hästen utvecklar olika symptom, bl.a. hälta, och kan drabbas av hovbenssänkning eller hovbensrotation. READ MORE
