  1. 21. On the influence of micro-and macroscopic surface modifications on bone integration of titanium implants

    Författare :Patricia Miranda Burgos; Göteborgs universitet; []
    Nyckelord :titanium; dental implants; surface modification; bone tissue; biomechanics; BMP-2;

    Sammanfattning : Background: Osseointegrated titanium implants are routinely used in clinical denstistry as anchorage units for dental prostheses. Although the overall clinical results are good, there are clinical situations when an optimized implant healing is desirable, for instance in order to shorten healing periods and to allow immediate loading.

  3. 22. Parametric stability analyses for fluid-loaded thin membranes

    Författare :Yang Zhou; Anders Eriksson; Håkan Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Hydro-static load; Multi-parametric loading; Bifurcations; Generalized path-following; Fold lines; Mesh eects; Augmenting equations; Generalized eigenproblem; Solution surface.; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Membrane structures are commonly used in many elds. The studies of thesestructures are of increasing interest. The two projects focus on the evaluations ofequilibrium states for uid-pressurized membranes under dierent loading conditions,and the corresponding instability behavior. LÄS MER

  4. 23. Sustainable Surface Functionalization of Lightweight Materials : Cerium Oxide Nanoparticles Replacing Chromium in Anodic Coatings and Carbon Nanomaterials for Lightning Strike Protection

    Författare :Thirza Poot; Kajsa Uvdal; Linnéa Selegård; Zhang-Jun Hu; Mats Eriksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Aviation accounts for 2-3% of the carbon dioxide emitted globally. One way to reduce emissions is to develop and introduce sustainable, functional, lightweight materials and coatings that increase the lifetime and fuel efficiency of aircraft. LÄS MER

  5. 24. On loading protocols and abutment use in implant dentistry. Clinical studies

    Författare :Catharina Göthberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; abutment design; clinical studies; dental implants; dental prosthesis; implant-supported; gene expression; health; immediate implant loading; marginal bone loss; osseointegration; prosthodontics; risk factors; smoking; treatment outcome;

    Sammanfattning : ABSTRACT Research questions: The influence of immediate or delayed loading and the use of abutments in implant dentistry with regard to peri-implant tissues and the effect of risk parameters. Methodology: Fifty partially edentulous patients each received three Brånemark TiUnite™ implants. LÄS MER

  7. 25. Asymmetric lateral loading of the human trunk

    Författare :Qiang-Min Huang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Eccentric; concentric; isokinetic; electromyography; co-activation; trunk; spinal biomechanics; contraction patterns; lateral bending; lifting and lowering; balance; kinematics; postural control; IAP; support translation.;

    Sammanfattning : The overall aim of this thesis was to characterize the biomechanics and neuromuscular control of the human trunk in response to asymmetric lateral loading. The pulling force and strength capacities as well as muscle activation patterns, trunk kinematics and postural balance in relation to lateral trunk flexion and loading were given special consideration.
