    Författare :Tania Loaiza; Peter Hedström; Mårten Olsson; Steve Ooi; Prasath Babu; Harry Bhadeshia; KTH; []
    Nyckelord :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;

    Sammanfattning : 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.

    Sammanfattning : Apoptosis is one of the most common types of cell death. Under physiological conditions, it plays an essential role in removal of damaged and potentially harmful cells. Excessive apoptosis has however been linked to a number of diseases including proteinuric kidney disease and DKD, and is believed to enhance the disease progression. LÄS MER

    Sammanfattning : Mikroskopi är idag ett fundamentalt verktyg inom forskning, där det tillåter oss att skåda in och utforska våra prover i hög detalj. Mycket utav utvecklingen av nya mikroskopimetoder har strävat efter att öka den detaljnivå vi kan uppnå. LÄS MER

  7. 5. Methods and models for 2D and 3D image analysis in microscopy, in particular for the study of muscle cells

    Författare :Patrick Karlsson Edlund; Ewert Bengtsson; Joakim Lindblad; Carolina Wählby; Fritz Albregtsen; Uppsala universitet; []
    Nyckelord :medical image analysis; image segmentation; fluorescence microscopy; cytometry; human skeletal muscle;

    Sammanfattning : Many research questions in biological research lead to numerous microscope images that need to be evaluated. Here digital image cytometry, i.e., quantitative, automated or semi-automated analysis of the images is an important rapidly growing discipline. LÄS MER
