Advanced examination of historical masonry bridges for future traffic demands

Eugen Brühwiler, Alix Grandjean

The key to extending the service life of a historical masonry bridge is an accurate examination of its actual performance. This paper presents a risk-based safety approach which introduces a risk matrix illustrating the risk presented by a structure as a f ...

Bone reactions to controlled loading of endosseous implants: a pilot study

John Botsis, Joël Cugnoni

Objectives: To validate an experimental setup designed to apply load onto bone tissue using osseointegrated implants in a rabbit model. Specifically, (1) to design an apparatus capable of generating controlled forces, (2) to assess implant placement, maint ...

Microstimulations at the bone implant interface upregulate osteoclast activation pathway

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

Peri-implant bone resorption after total joint arthroplasty is a key parameter in aseptic loosening. Implant wear debris and biomechanical aspects have both been demonstrated to be part of the bone resorption process. However, neither of these two paramete ...

Fetal bone cells for tissue engineering

In this thesis, the potential use of fetal bone cells for tissue engineering was evaluated. At first, fetal bone cells were characterized in vitro regarding their proliferation rate, the induction of their osteoblastic phenotype, and their antigenicity. Th ...

Sacrificial bonds and hidden length dissipate energy as mineralized fibrils separate during bone fracture

Georg Fantner

Properties of the organic matrix of bone(1) as well as its function in the microstructure(2) could be the key to the remarkable mechanical properties of bone(3). Previously, it was found that on the molecular level, calcium-mediated sacrificial bonds incre ...

Orthopedic implants used as drug delivery systems

Bastian Peter

Total Hip Replacement (THR) is today a routine procedure executed more than 800'000 times per year worldwide. THR gives generally satisfactory results, although the quality of outcome is inversely proportional to the age of the patient. In parallel, there ...

Quantitative damage detection in CFRP composites: coupled mechanical and electrical models

William Curtin

Electrical resistance in carbon-fiber reinforced polymers has been shown experimentally to be a sensitive measure of internal damage. To quantify the dependence of electrical resistance on mechanical fiber damage at the micromechanical level, a numerical e ...

Age-related decline of gait control under a dual-task condition

Kamiar Aminian, Bijan Najafi

High stride-to stride variability and the inability to walk and talk at the same time have been associated with an increased risk of falling (1;2). The aim of this study was to compare stride-to-stride variation in stride length and velocity beween communi ...
