Simulated joint and muscle forces in reversed and anatomic shoulder prostheses

Alexandre Terrier, Alain Farron, Francesco Merlini, Adrian Reist

Reversed shoulder prostheses are increasingly being used for the treatment of glenohumeral arthropathy associated with a deficient rotator cuff. These non-anatomical implants attempt to balance the joint forces by means of a semi-constrained articular surf ...

Strength of the baseplate fixation of a reversed shoulder prosthesis

Stephanie Kochbeck

A reversed shoulder prosthesis is the general treatment of glenohumeral arthritis and concomitant rotator cuff arthropathy. However, failure due to loosening of the components remains a concern. The purpose of this study was to examine the forces that occu ...

Sensors for Applications in Magnetic Resonance Environments

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet

This paper analyzes sensing methods compatible with magnetic resonance imaging (MRI) and functional MRI (fMRI) reported in the literature, and presents the three generations of MR-compatible force/torque sensors we have developed for robotic systems to int ...

Micro- and nano-electrostatic force fields

Martin Jenke

Electro-static or electro-dynamic fields generated by micro- or nano-electrodes are today widely used in many different fields, such as micro- and nanogripping, "lab on a chip", and "lab in a cell", for the purpose of manipulation, separation, or analysis ...

Scanning near-field optical microscope based on double-resonant fiber probe montage and its operation in liquids - art. no. 67282D

Giovanni Dietler, Kanat Dukenbayev

The operation of the scanning near-field optical microscope based on the double-resonant montage of a fiber probe onto the tuning fork (working frequency of the latter, that is 32 kHz, coincides with the second resonance frequency of the bending oscillatio ...

Simulation of the flow-reversal effect in dual-channel CICC for ITER

Pierluigi Bruzzone, Luca Bottura

The discovery of an upward counter flow of helium in the outer annulus of the vertically oriented and top-to-bottom cooled ITER PF-FSJS (Poloidal Field Coil-Full Size Joint Sample) in 2002 led to closer investigations of the effect because it may lead to a ...

Characterization and optimization of liquid electrodes for lateral dielectrophoresis

Philippe Renaud, Thomas Michael Braschler, Harald Van Lintel, Nicolas Demierre, Olof Pontus Linderholm, Urban Seger

Using the concept of insulator-based "electrodeless" dielectrophoresis, we present a novel geometry for shaping electric fields to achieve lateral deviation of particles in liquid flows. The field is generated by lateral planar metal electrodes and is guid ...

The role of calcium and magnesium in the concrete tubes of the sandcastle worm

Georg Fantner

Sandcastle worms Phragmatopoma californica build mound-like reefs by sticking together large numbers of sand grains with cement secreted from the building organ. The cement consists of protein plus substantial amounts of calcium and magnesium, which are no ...

Young's law and the effects of interfacial energy on the pressure at the solid-fluid interface

Ivan Lunati

In a recent paper [R. Finn, Phys. Fluids 18, 047102 (2006)] the attention has been drawn on the tension component perpendicular to the solid surface that results from Young's law. Considering the problem of a solid sphere floating in zero gravity, it has b ...

Multiphysical Brushless DC Motor Optimization Process

Yves Perriard, Miroslav Markovic

An original analytical determination of the force acting on the moving coil in an electromagnetic actuator is presented. The actuator magnetic field is solved analytically using the Schwarz-Christoffel (SC) mapping. The SC integral is solved analytically u ...
