  1. 6. Outcome after surgery for isthmic spondylolisthesis and degenerative disc disease

    Författare :Peter Endler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Individuals with isthmic spondylolisthesis and lumbar degenerative disc disease may have low back and leg pain. Those with persistent symptoms non-responsive to conservative treatment are sometimes treated surgically. Various surgical methods have been introduced, but long-term outcome comparisons are scarce.

  3. 7. Single implants in the anterior maxilla in young adults

    Författare :Nicole Winitsky; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Single anterior implants are frequently used in the treatment of patients with single anterior tooth loss. Compared with other types of implant treatments, single implants are commonly performed in younger patients where the cause of tooth loss often is non-inflammatory. LÄS MER

  4. 8. Position-sensitive germanium detectors for gamma-ray tracking, imaging and polarimetry

    Författare :Anton Khaplanov; Bo Cederwall; Araceli Lopez-Martens; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik;

    Sammanfattning : Modern germanium detectors are often manufactured with two-dimensionally segmented electrical contacts. Signals induced in each segment are read out simultaneously when a photon is detected. Detailed pulse shape analysis (PSA) of these signals allows to resolve positions of individual γ-ray interactions with a precision of at least a few mm. LÄS MER

  5. 9. Combinatorics of genome rearrangements and phylogeny

    Författare :Niklas Eriksen; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis deals with combinatorial problems taken frombioinformatics. In particular, we study the problem ofinferring distances between bacterial species by looking attheir respective gene orders. We regard one of the gene ordersas a permutation of the other. LÄS MER

  7. 10. Conformations of Flexible Oligosaccharides : Molecular Simulations and NMR spectroscopy

    Författare :Robert Pendrill; Göran Widmalm; Jens Duus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Oligosaccharide; Conformation; NMR spectroscopy; MD simulations; organisk kemi; Organic Chemistry;

    Sammanfattning : The conformational preferences of several oligosaccharides are investigated herein using a combination of NMR spectroscopy and molecular dynamics (MD) simulations, focusing on the torsion angles associated with the glycosidic linkages.Strategies for obtaining usable J-HMBC spectra for carbons with an adjacent 13C label are described.
