  1. 1. Image processing on optimal volume sampling lattices : Thinking outside the box

    Författare :Elisabeth Schold Linnér; Robin Strand; Ewert Bengtsson; Alexandre Falcão; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BCC; FCC; aliasing; distance transform; segmentation; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : This thesis summarizes a series of studies of how image quality is affected by the choice of sampling pattern in 3D. Our comparison includes the Cartesian cubic (CC) lattice, the body-centered cubic (BCC) lattice, and the face-centered cubic (FCC) lattice. LÄS MER

  3. 2. Detection and analysis of genetic alterations in normal skin and skin tumours

    Författare :Åsa Sivertsson; KTH; []
    Nyckelord :single cell; DNA sequencing; p53; mutation; UV; BCC; pyrosequencing; malignant melanoma; N-ras;

    Sammanfattning : The investigation of genetic alterations in cancer-relatedgenes is useful for research, prognostic and therapeuticpurposes. However, the genetic heterogeneity that often occursduring tumour progression can make correct analysischallenging. LÄS MER

  4. 3. Development and Application of ToF-SIMS for Clinical and Microbiological Analysis

    Författare :Kelly Dimovska Nilsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ToF-SIMS; Imaging mass spectrometry; Antibiotic resistance; Basal cell carcinoma; Gas cluster ion beam; GCIB; Time-of-flight secondary ion mass spectrometry; BCC; Escherichia coli; E. coli; FabF; DapF; Lpp; Lipid A; ECAcyc; Depth profile;

    Sammanfattning : The aim of the work of this thesis was to further the implementation of timeof-flight secondary ion mass spectrometry (ToF-SIMS) in biological analysis and to generate new knowledge from the samples analysed. ToF-SIMS is a chemical analysis technique. LÄS MER

  5. 4. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter

    Författare :Martin Andersson; Eva Lindström; Stuart Jones; Uppsala universitet; []
    Nyckelord :Dissolved organic matter; BCC; biodiversity; functional redundancy; Mikrobiologi; Microbiology;

    Sammanfattning : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop.
