Experimental and numerical investigations on the fluid contribution to the tensile-compressive mechanical behavior of the bovine periodontal ligament

Orthodontic treatments are all based on the experimental evidence that teeth can be forced to move in the dental arch by means of applied mechanical forces. Since it allows for prediction of dental mobility, the mechanical characterization of the tissues i ...

Molecular energy dissipation in nanoscale networks of dentin matrix protein 1 is strongly dependent on ion valence

Georg Fantner

The fracture resistance of biomineralized tissues such as bone, dentin, and abalone is greatly enhanced through the nanoscale interactions of stiff inorganic mineral components with soft organic adhesive components. A proper understanding of the interactio ...

KFM detection of quantified charges injected into a thin SiO2 layer containing Si nps embedded by ultra low energy ion implantation using stencil lithography

Jürgen Brugger, Andreea Veronica Savu, Marc Antonius Friedrich van den Boogaart

Non volatile flash memories based on nanoparticles (nps) are one of the identified routes to a further downscaling of future CMOS technology. New features such as Coulomb blockade and quantized charging effects can appear at room temperature only for a lim ...

An exact formula for "tooth-to-tooth" permeance

Yves Perriard, Marcel Jufer, Miroslav Markovic

We present a new, completely original exact method to determine the permeance between two opposing iron teeth. This configuration is important because it is often encountered in electrical machines and apparatus. The method is based on conformal mapping. T ...

Determination of tooth cogging force in a hard-disk brushless DC motor

Yves Perriard, Marcel Jufer, Miroslav Markovic

The paper proposes a new method to determine the tooth cogging force in a brushless DC (BLDC) motor which is used in a hard-disk application. This force might be a source of tooth vibrations and motor noise. In the new method, the permanent-magnet (PM) pol ...

With applications to the periodontal ligament: a nonlinear large strain viscoelastic law

Jörn Justiz

The soft tissue, called periodontal ligament (PDL), that connects the alveolar bone and the tooth root accounts to a large extent for the mobility, stress-distribution and, due to its viscoelastic properties, damping of the bone-tooth complex. The accurate ...

Analyse et prédiction de la baisse de rendement des turbines Francis par cavitation à bulles

The setting level of an hydraulic machine, specially for low head machines, is decided with respect to the possible alteration of the efficiency due to the cavity development. This alteration can easily be noticed by plotting the evolution of the efficienc ...
