  1. 1. Infections associated with percutaneous osseointegrated titanium implants for limb prostheses

    Författare :Jonatan Tillander; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteomyelitis; osseointegration; percutaneous implant; titanium; amputation; long-term risk; clinical presentation; biofilm;

    Sammanfattning : Femoral amputation is a devastating event. Percutaneous, bone anchored prosthetic systems reduce problems associated with socket suspended prostheses, but the design is inherently vulnerable to infection. LÄS MER

  3. 2. The Influence of Composition and Hot Processes on Heat Affected Zone and Weld Metal Behavior and Mechnacal Properties of Ti Grade 5 and Stainless Steel

    Författare :Esa Kivineva; KTH; []
    Nyckelord :Stainless steel; Duplex stainless steel; Titanium Grade 5; Ti-6Al-4V; Microstructure; Mecjhanical properties; Welding; Welding simulation;

    Sammanfattning : This thesis discusses on results of experiments carried outwith austenitic, duplex and super duplex stainless steels andTi-6Al-4V. In these it has been seen that the heat cycle duringwelding or weld simulation has a great effect on the propertiesof thematerials. LÄS MER

  4. 3. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Författare :Mikael Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Sammanfattning : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. LÄS MER

  5. 4. 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
