  4. 17. Microstructural Decay in High-Strength Bearing Steels under Rolling Contact Fatigue

    Author : Tania Loaiza; Peter Hedström; Mårten Olsson; Steve Ooi; Prasath Babu; Harry Bhadeshia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microstructural decay; microscopy; rolling contact fatigue; Hybrid 60 steel; Bearing steel; 52100; dislocations; ferrite microbands; Mikrostrukturell nedbrytning; mikroskopi; rullande kontaktfatigue; Hybrid 60-stål; dislokationer; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The work presented in this thesis aims to enhance our understanding of material decay in high-strength steels used for bearing applications. The primary objective is to investigate the microstructural changes in two high-strength steels: 52100 steels, a popular bearing steel, and Hybrid 60, a relatively new bearing steel designed for long fatigue life and use at elevated temperatures.

  5. 18. Microarray Analysis of mRNA Decay Assays and Prediction of Drug Target Conservation

    Author : Alexandra Jauhiainen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microarray analysis; mRNA decay; evolutionary conservation; ecotoxicology; environmental risk assessments; ecotoxicology;

    Abstract : This thesis contains two papers concerning (I) the evolutionary conservation of drug targets and its potential use in environmental risk assessments and (II) mRNA degradation as a control mechanism during osmotic stress in the yeast S. cerevisiae. Environmental risk assessments are needed for the approval of new pharmaceutical compounds. READ MORE

  6. 19. On Alpha-decay and Alpha Clustering

    Author : Gordana Dodig Crnkovic; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The half-life for the Alpha-decay of 212 Po is calculated within a harmonic oscillator representation. Clustering induced by the nuclear interaction appear by considering alarge configuration space. The role of clusterisation in the alpha-decay process isclearly demonstrated. READ MORE

  7. 20. A Trilogy of Mass A=61 : Superdeformed Structures, Exotic Decay, and Isospin Symmetry

    Author : Lise-Lotte Andersson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fusion-evaporation reactions; cranked Nilsson-Strutinsky calculations; prompt particle decay; shell-model calculations; mirror nuclei; Fysicumarkivet A:000; high-spin states; Superdeformation;

    Abstract : Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. READ MORE
