1. 11. 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

3. 12. Adsorption and reactions of sulfur dioxide on TiO2 surfaces : Fundamental studies on single crystals and nanoparticles

   Författare :David Langhammer; Lars Österlund; Anders Sandell; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Titanium dioxide (TiO2) is a material that is well-known among researchers in environmental science but is perhaps less well-known by the general public. It is commonly used in white paint because of its ability to scatter visible light, and for this reason it is manufactured at a large industrial scale. LÄS MER

4. 13. On tissue reactions to dentin as a bone substitute material

   Författare :Payam Farzad; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grafted dentin; tissue reaction; bone blocks; dental implants; experimental study;

   Sammanfattning : Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ability equivalent to autogenous bone but without the limitations of allogenic, xenogenic and synthetic bone are constantly ongoing.

5. 14. Recovery of kraft black liquor with direct causticization using titanates

   Författare :Ingrid Nohlgren; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : The feasibility of direct causticization of kraft black liquor using titanates has been evaluated. This has been done by studying the kinetics of the reaction between sodium tri-titanate and sodium carbonate and describing the kinetics by appropriate reaction models. LÄS MER

7. 15. On enhancement of bone formation using local drug delivery systems

   Författare :Ali Alenezi; Ann Wennerberg; Malmö universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone formation; local drug delivery systems;

   Sammanfattning : Introduction: Despite that many reports have confirmed the long-term clinical success rates associated with implant treatment, implant failure to achieve and maintain osseointegration still occurs in many cases. Local and sustained drug release at the bone-implant interface is one of the strategies that have been suggested to improve the osseointegration. LÄS MER
