  4. 3. Influence of carbides and nitrides on corrosion initiation of advanced alloys : A local probing study

    Författare :Eleonora Bettini; Jinshan Pan; Thomas Ladwein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbides; nitrides; microstructure; CoCrMo alloys; duplex stainless steels; localized corrosion; transpassive dissoluti on; elemental depletion; AFM; TEM; SEM.;

    Sammanfattning : Advanced alloys often present precipitated carbides and nitrides in their microstructure following exposure to elevated temperatures. These secondary phases are usually undesirable, because potentially deleterious for the corrosion and mechanical performances of the material. LÄS MER

  5. 4. On dental ceramics and their fracture : a laboratory and numerical study

    Författare :Wen Kou; Göran Sjögren; Tore Dérand; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental ceramics; Finite element analysis; Fixed partial denture; Fracture; Numerical modeling; Surface treatment; Biomaterials; Biomaterial; odontologi; Odontology;

    Sammanfattning : Background Surface treatments and irregularities in the surfaces may affect the fracture of ceramics. The effects of various treatments on the surface texture of different types of ceramic cores/substructures was therefore qualitatively, quantitatively and numerically evaluated. LÄS MER

  7. 5. Topical anesthesia of the tympanic membrane : an experimental animal study

    Författare :Sten-Hermann Schmidt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Topical anesthesia; middle ear; tympanic membrane; cochlea; collagen fibres; lidocaine; 96 % phenol; Bonain s liquid; auditory brainstem response; ototoxicity; cytocochleogram; scanning electron microscopy; rat; guinea pig;

    Sammanfattning : Myringotomy plays an important role in otological therapy. The procedure requires an efficient anesthesia, which can be obtained without general anesthesia. However, the use of local anesthetics on the tympanic membrane (TM) has been abandoned in many places, as general anesthesia has been readily available. LÄS MER
