1. 16. On the bone response to different implant textures. A 3D analysis of roughness, wavelength and surface pattern of experimental implants

   Författare :Carin Hallgren Höstner; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surface modification; surface texture; roughness; surface evaluation; in vivo studies.;

   Sammanfattning : PurposeThe purpose of the present thesis was to investigate the bone response to different isotropic, anisotropic and organised surface patterns.Material and methodsImplant surfaces have been modified with different techniques (abrasive blasting, turning, milling, photolithography or laser ablation).

3. 17. On the hydrodynamic lubrication in tilting pad thrust bearings

   Författare :Sergei B. Glavatskikh; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Sammanfattning : The primarily objective of this work was to investigate the performance of environmentally adapted synthetic oils in the hydrodynamic lubrication regime. A special test facility has been designed and manufactured for this purpose. The facility contains two equalising tilting pad thrust bearings typical of design in general use. LÄS MER

4. 18. Experimental and computational investigation of the roll forming process

   Författare :Michael Lindgren; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollforming; Roll Forming; Flexible roll forming; Rullformning; Simulering och experimentell undersökning av rullformningsprocessen;

   Sammanfattning : One of the first questions to consider when designing a new roll forming line is the number of forming steps required to produce a profile. The number depends on material properties, the cross-section geometry and tolerance requirements, but the tool designer also wants to minimize the number of forming steps in order to reduce the investment costs for the customer.

7. 20. Evaluation of patients with an anterior cruciate ligament rupture, before and after reconstruction, with special emphasis on the use of the KT-1000 arthrometer

   Författare :Ninni Sernert; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anterior cruciate ligament; KT-1000 arthrometer; knee evaluation systems; knee; laxity; right left knee laxity difference;

   Sammanfattning : The aim of the study was to analyse the outcome and function after anterior cruciate ligament(ACL) reconstruction using different evaluation systems. Special emphasis was placed on thesagittal knee laxity as measured with the KT-1000 arthrometer. LÄS MER
