Magnetic resonance elastography (MRE), a phase contrast MRI technique, images the propagation of applied mechanical waves in tissue, allowing shear stiffness to be quantified in vivo. This MRE technique has been validated with static mechanical compression tests. Dynamic mechanical analysis (DMA) may be a more appropriate comparison to MRE because it directly measures the shear modulus dynamica...

Molecular and behavioral evidence suggests that acid-sensing ion channels (ASICs) contribute to pain processing, but an understanding of their precise role remains elusive. Existing ASIC knock-out mouse experiments are complicated by the heteromultimerization of ASIC subunits. Therefore, we have generated transgenic mice that express a dominant-negative form of the ASIC3 subunit that inactivate...

The goal of the study, is to specify mechanical properties of epoxy and acrylic-based adhesives commonly used for bonding of metal connections. For this reason, the bulk specimens, manufactured from Devcon A and Akfix-E300 as epoxy material, Erde GTR and Erde GTS as acrylic based adhesive material, were cast in accordance with the test standards. The mechanical properties of the specimens obtai...

OBJECTIVES The aim of the study was to investigate the effect of fetal undernutrition on the passive mechanical properties of skeletal muscle of weaned and young adult rats. INTRODUCTION A poor nutrition supply during fetal development affects physiological functions of the fetus. From a mechanical point of view, skeletal muscle can be also characterized by its resistance to passive stretch. ...

with many years of construction and application of common concrete, researchers have always been searching for a better composition. one of the notable ideas for achieving such a composition is using recycled materials. one of the materials which is suitable for environment and constant development is damaged tires .for studying mechanical properties of concrete containing tire particles, a ser...

In this research, the high-energy planetary mill was employed to produce nanocrystalline Ti-50Al(γ)(at%) powders. Initial powders were mechanically alloyed in 99.9999% and 90% purities of Argon and also Air atmosphere with alloying times up to 50h. The effect of impurity of Argon atmosphere on the microstructure and the rate of phase transformation of Ti-50Al were investigated during mechanical...

In order to study passing ability of lunar rover in lunar soil, the mechanical parameters between lunar wheel and lunar soil should be analyzed. The mechanical parameters can reflect the mechanical relationship between lunar rover wheel and regolith. These parameters include sinkage, drawbar pull, driving torque, motion resistance and slip. In this paper, these parameters are measured by soil b...

OBJECTIVE Considering that periodontal ligament simulation may influence the stress distribution over teeth restored with intraradicular retainers, this study aimed to assess the combined effect of mechanical cycling and periodontal ligament simulation on both the bond strength between fiber posts and root dentin and the fracture resistance of teeth restored using glass fiber posts.
