  1. 1. Caries Prevention in Patients Undergoing Orthodontic Treatment

    Författare :Hanna Enerbäck; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caries; fluoride; caries incidence; caries prevalence; caries risk; orthodontics; mouth rinse; risk assessment; toothpaste;

    Sammanfattning : Background: Scientifically based guidelines to predict and prevent caries during orthodontic treatment with fixed orthodontic appliances are lacking. Aim: The overall aim of this thesis was to improve caries risk assessment before orthodontic treatment, as well as to evaluate caries risk and improve caries prevention during treatment. LÄS MER

  3. 2. On the aetiology of aseptic loosening in joint arthroplasties, and routes to improved cemented fixation

    Författare :Mikael Sundfeldt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; knee prosthesis; aseptic loosening; polyethylene particles; endotoxin; bone cement; sodium fluoride;

    Sammanfattning : Background: Aseptic loosening is the most common single cause for revisions in major joint arthroplasties worldwide. Different theories for aseptic loosening have been discussed during the last two decades. There is a need for improving fixation in both cemented and uncemented implants. LÄS MER

  4. 3. In the confines of Cu(In,Ga)Se2 thin film solar cells with rear surface passivating oxide layers

    Författare :Dorothea Ledinek; Marika Edoff; Charlotte Platzer Björkman; Jan Keller; Christian Kaufmann; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali; Alumina; Back contact; CIGS; CIGSe; Hafnia; Passivation; Rear contact; Sodium fluoride; Ultra-thin; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : The material supply to build renewable energy conversion systems needs to be considered from both a cost and an energy security perspective. For Cu(In,Ga)Se2 (CIGS) thin film solar cells the use of indium in the absorber layer is most problematic. LÄS MER

  5. 4. Study on some phenomena of slag in steelmaking process

    Författare :Liushun Wu; Sichen Du; Carlo Mapelli; KTH; []
    Nyckelord :Slag viscosity; calcium fluoride; fluid viscosity with particles; mixture viscosity; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The present work is to study slag phenomena in steelmaking process. In order to attain thegoal, a number of high temperature experiments and simulation experiments were carried out. Four master slags were used to study the effect of CaF2 on slag viscosity. LÄS MER

  7. 5. On Caries Prevention Using Fluoridated Toothpicks and Dental Flosses

    Författare :Barbro Särner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The prevalence of approximal dental caries is still high worldwide in all age groups. The aim was to evaluate different aspects of fluoridated toothpicks and dental flosses in relation to caries prevention with the emphasis on the approximal area. LÄS MER
