On the basis of the thermokinetics of the hydrogen (deuterium) evolution reaction and the thermodynamics of Pd+H(D) system, we analytically and numerically discuss effects of temperature on the loading ratio of hydrogen (deuterium) absorption into electrodes of β-phase PdHx (PdDx) under the galvanostatic charging condition. It is found that the change of the loading ratio with temperature depen...

Remote loading systems using an electromagnetic beam is affected by discontinuous piecewise constant loading voltage. The characteristics of these remote dynamic systems under charge are investigated. Varied behaviour of the systems with discontinuous charge is found due to environment perturbation compared to systems under continuous voltage charge with a wired link. A theoretical and numerica...

The implants failure may be caused by micromotion and stress exerted on implants during the phase of bone healing. This concept is especially true in case of implants placed in atrophic ridges. So the primary stabilization and fixation of implants are an important goal that can also allow immediate loading and oral rehabilitation on the same day of surgery. This goal may be achieved thanks to t...

We report the simultaneous rehabilitation of an edentulous patient with a hybrid (zygomatic and conventional implants) all-on-four implant-supported prosthesis for the maxilla and a standard (conventional implants) all-on-four implant-supported prosthesis for the mandible. The transfer impression was made with a multifunctional guide and the upper and lower prostheses were placed 24h postoperat...

Presented is a study of the tripping strength of asymmetrical longitudinal plate stiffeners subjected to a combination of axial and lateral loads. The loaded edges were taken to be simply supported. The method of analysis is based on the principle of minimum total potential, and ten displacement functions were used to describe the deformations of the plate and stiffeners. First yielding was use...

BACKGROUND Increased impulsive loading and muscle co-contraction during gait have been observed in individuals with knee osteoarthritis. Proprioceptive deficits in this population may contribute to these effects. Proprioception has been shown to improve with the combination of stochastic resonance electrical stimulation and a knee sleeve in knee osteoarthritis. Our goal was to determine whether...

Mechanical loading plays a key role in altering macroscopic and microscopic bone structure through functional adaptation; however, the anisotropic micro-organization of collagen and biological apatite (BAp) in adaptively created bone tissue is not well understood in spite of its importance in the mechanical function of bone. In this study, we artificially applied axial compressive loading (15N ...

The current study was designed to investigate the mechanical response of a polyetheretherketone-on-polyethylene total knee replacement device during a deep squat. Application of this high-demand loading condition can identify weaknesses of the polyetheretherketone relative to cobalt-chromium. This study investigated whether the implant is strong enough for this type of loading, whether cement s...

If a discrete elastic system with frictional interfaces is subjected to periodic loading, the eventual steady-state response may depend on the initial condition or an initial transient phase of the loading history. In cases where shakedown is possible, it is known that it will occur for all initial conditions if there is no coupling between slip displacements and normal contact tractions, but t...
