  1. 11. Structural Safety Analysis of Bow-Doors

    Författare :Ulf Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship design; structure; safety; fatigue.; arm; IACS S8; damage; bow-door; analysis;

    Sammanfattning : Bow-doors are one of the most vulnerable parts on a RoRo-vessel. At the same time, they are necessary for the profitability of todays RoRo-vessels.The minimum design rules for bow-door systems, stated in the International Association of Classification Societies (IACS) S8, constitute the basis for the class rules.

  3. 12. On dental implant failure and patient-related factors

    Författare :Malin Olsson Malm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implants; implant failure; long term; implant surface; multivariable logistic regression; case-control study; edentulous jaw; gene expression analysis; early implant failure; patient factors;

    Sammanfattning : Dental implants function as anchorage for dental prostheses. In a small number of cases, osseointegration fails to establish or be maintained around the implants, but the reasons for these failures are not yet fully understood. LÄS MER

  4. 13. Wellbore stability analysis based on a new true-triaxial failure criterion

    Författare :Adel Al-Ajmi; Robert Zimmerman; Bernt Aadnoy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failure criteria; Mogi failure criterion; intermediate principal stress; polyaxial test data; wellbore stability; Geoengineering and mining engineering; Geoteknik och gruvteknik;

    Sammanfattning : A main aspect of wellbore stability analysis is the selection of an appropriate rock failure criterion. The most commonly used criterion for brittle failure of rocks is the Mohr-Coulomb criterion. LÄS MER

  5. 14. Capacitive Biosensor - A Tool for Ultrasensitive Analysis : Application in Clinical Analysis and Process Monitoring

    Författare :Kosin Teeparuksapun; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitive Biosensor; Ultrasensitive Analysis; Clinical Analysis; Bioprocess Monitoring; Human Serum Albumin; HIV-1 p24; Host Cell Proteins; Protein A; Current Pulse;

    Sammanfattning : Increasing demands for highly sensitive, accurate, fast and portable analytical assays have led to the development of new analytical tools. The integration of highly specific biological sensing elements and appropriate transducers has enabled design of even more efficient biosensor devices for the detection of target substances. LÄS MER

  7. 15. Interfacial Adhesion Failure : Impact on print-coating surface defects

    Författare :Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER
