  2. 11. Effect of surface characteristics on cellular adherence and activity

    Author : Marjan Dorkhan; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria; microbial biofilm; dental implant; streptococci; oral bacteria; salivary pellicle; early colonizers; titanium oxide; microbial activity; oral keratinocytes; gingival fibroblasts; cell attachment; surface modification; anodic oxidation; anatase;

    Abstract : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. READ MORE

  4. 12. Implementation of MRI gel dosimetry in radiation therapy

    Author : Sven Bäck; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; uncertainty; detector; dosimeter; ferrous ions; gel dosimetry; magnetic resonance imaging; monomers; polymerisation; proton; treatment planning verification; radiation therapy; cancerology; Cytologi; onkologi; cancer;

    Abstract : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. READ MORE

  5. 13. Regeneration in periodontal and endosseous implant treatment

    Author : Lisa Mayfield; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Odontology; guided tissue regeneration; Pressure sensitive periodontal probe; intraosseous defects; guided bone regeneration; EDTA root surface conditioning; bioabsorbable membrane; stomatology; Odontologi;

    Abstract : In a series of clinical studies regenerative procedures for periodontal disease treatment were evaluated. A reproducibility study of probing measurements using a manual periodontal probe and 3 pressure-sensitive probes showed that measurements obtained using the manual probe were the most repeatable.

  6. 14. On the role of surface properties for implant fixation : From finite element modeling to in vivo studies

    Author : Patrik Stenlund; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implant stability; Removal torque; Surface roughness; Surface chemistry; Finite element analysis; Experimental; In vivo; Osseointegration; Mechanical loading; Bone regeneration; Biomechanics;

    Abstract : The aim of this thesis was to gain a deeper understanding of the factors contributing to the fixation of bone-anchored implants, especially with regard to surface chemistry, surface topography and implant loading. The methodology used in the thesis ranges from systematic bench studies, computer simulations, experimental in vivo studies, to load cell measurements on patients treated with bone-anchored amputation prostheses.

  7. 15. Dynamic Soil-Structure Interaction Analysis of High-Speed Railway Bridges : Efficient modeling techniques and Experimental testing

    Author : Abbas Zangeneh Kamali; Costin Pacoste; Raid Karoumi; Andreas Andersson; Pedro Galvín; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway bridge dynamics; Soil-structure interaction; Resonance; Analytical solution; Non-proportional damping; Complex mode; Field measurements; FE Model updating; Järnvägsbrodynamik; Jord-bro interaktion; Resonans; Analytisk lösning; Icke-proportionell dämpning; Komplex mod; Fältmätningar; FE Modelluppdatering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The work reported in this thesis presents a general overview of the resonant response of high-speed railway bridges considering soil-structure interaction. The study aims to identify the effect of the surrounding and underlying soil on the global stiffness and damping of the structural system. READ MORE
