  1. 36. Osteotomy for gonarthrosis - with special reference to the tibial callus distraction technique

    Författare :Göran Magyar; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; radiography; arthroplasty; complications; coating; hydroxyapatite; external fixator; femoral osteotomy; hemicallotasis; Knee osteoarthritis; tibial osteotomy; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Osteotomy is used for correction of the altered load on the gonarthrotic knee joint. It can be performed above or below the knee. Clinical results depend on the correction after bone healing. LÄS MER

  3. 37. On the fluid mechanics of electrochemical coating and spray painting

    Författare :Pedro Olivas; KTH; []
    Nyckelord :mass transfer; electrochemical coating; ion transport; forced convection; diffusion; magnetoelectrolysis; electrolyte; limiting current; numerical simulation;

    Sammanfattning : Finite-volume methods have been used for modeling of fluidflows involved in forced convection electrochemical coating androtating spray painting systems. Electrodeposition on a singlecircular cylinder under forced convection for Reynolds numbers10 and 200 was simulated. LÄS MER

  4. 38. Polymer-coated paper and board - Role of substrate, polymer characteristics and additives

    Författare :Thomas Schuman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface energy; latex; surface roughness; corona; contact angle; barrier properties; liquid sorption; surface treatment; calendering; poly vinyl alcohol ; coating;

    Sammanfattning : The surface roughness of paper or board has a significant influence on the homogeneity of an applied polymer film, and this thesis discusses how it may be improved by a surface treatment, e.g. high-temperature calendering or precoating. LÄS MER

  5. 39. Computed Tomography of Acetabular Cup Wear and Effect of Surface Roughness on Wear and Oxidation of UHMWPE Hip Prostheses

    Författare :Anneli Jedenmalm; Ulf Gedde; André Stark; Karin Jacobson; Nicklas Axén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip prostheses; Computed Tomography; Surface roughness; UHMWPE; Wear; Coating; Gamma-irradiation; pin-on-disc; hip simulator; Medical engineering; Medicinsk teknik;

    Sammanfattning : Aseptic loosening is the most common complication in total hip replacement (5- 10% at 10 years follow up). The magnitude of the problem is illustrated by the fact that about one million hip prostheses are implanted worldwide each year. LÄS MER

  7. 40. Assessment of acetabular cup wear with computed tomography and influence of surface roughness on wear of materials for hip prostheses

    Författare :Anneli Jedenmalm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip prostheses; Computed Tomography; Surface roughness; UHMWPE; Wear; Coating; γ-irradiation; pin-on-disc; hip simulator; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Over one million hip prostheses are implanted in patients worldwide each year and the need is increasing as the patient group of younger and more active patients is increasing. Many parameters affect the longevity of the implant, where aseptic loosening caused by wear debris is the most common reason for revision. LÄS MER
