    Sammanfattning : Age related hearing loss is a public health concern that restricts the possibilities of older persons to lead a healthy, social and active life. The present thesis aims to provide contemporary perspectives on age related hearing function and hearing loss in the general population, in early old age. LÄS MER

  4. 13. Etiology and early detection of pancreatic cancer

    Författare :Jingru Yu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pancreatic cancer is one of the most dismal malignancies. Although its incidence and prevalence are relatively low, the disease burden is still an important health issue, especially in terms of mortality. Primary prevention is of utmost importance for such detrimental disease, however, the underlying etiology remains largely unknown. LÄS MER

  7. 15. On the estrablishment of effective condition monitoring parameters for copper corrosion problems in mineral oil-filled electrical transformers

    Författare :Ramsey Jadim; Mirka Kans; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring parameters; corrosion problems; sulfur deposits; corrosion reaction mechanisms; transformer failures; CBM.; Maskinteknik; Mechanical Engineering;

    Sammanfattning : The power transformer is a critical equipment in which the protection process is essential for modern societies where continuous electric power supplies are required. Copper corrosion problems due to the formation of sulfur deposits on the copper windings of mineral oil-filled power transformers are considered a major issue that can lead to sudden failures, and in some cases, to costly fire and explosion accidents in the power plants.
