The equations of states (EOSs) inert metals are generally used as pressure scales in a high-pressure experiment. However, the thermodynamic model and method to constrain parameters EOSs these may cause deviations up 7% at 100 GPa room temperature, even higher pressures temperatures. In this study, we provide new approach for obtaining accurate EOS metals. First, use set models, within quasi-Deb...

Changes in swimbladder morphology in an Atlantic herring Clupea harengus with pressure were examined by magnetic resonance imaging of a dead fish in a purpose-built pressure chamber. Swimbladder volume changed with pressure according to Boyle's Law, but compression in the lateral aspect was greater than in the dorsal aspect. This uneven compression has a reduced effect on acoustic backscatterin...

Rock burst support of deep rock mass has always been a difficult problem in geotechnical engineering. Aiming at the mass, new type pressure yielding and energy-absorbing bolt system is designed this paper. The energy absorption characteristics laminated spring members with different wall thicknesses were studied by static axial compression test drop hammer dynamic impact test. experimental resu...

Natural kamacite samples (Fe92.5Ni7.5) from a fragment of the Gibeon meteorite were studied as proxy material for terrestrial cores to examine phase transition kinetics under shock compression range different pressures up 140 GPa. In situ time-resolved X-ray diffraction (XRD) data collected body-centered cubic (bcc) section that transforms high-pressure hexagonal close-packed (hcp) with sub-nan...

BACKGROUND Spinal cord compression is a known cause of spinal cord injury. The purpose of this study is to measure pressure response during graded spinal cord compression. This information will be important in evaluating the amount of canal compromise that can be tolerated before risking neurological injury secondary to cord compression. To date, there is no published study that has evaluated p...

The present study deals with the quasi-static and high strain rate characterization of Kevlar-129 based thermoplastic composites. Two different matrices, namely, Polypropylene (PP) Polyetherimide (PEI) were used to manufacture composite laminates. Quasi-static compression tests performed at rates 0.041 s ?1 0.045 . High using a split Hopkinson pressure bar apparatus within ranging from 2548 437...

We have studied the ${\mathrm{H}}_{2}\mathrm{O}$ ice VII--ice X phase transition at room temperature by performing three quasicontinuous synchrotron time-resolved x-ray-diffraction experiments in a dynamic diamond anvil cell, reaching pressures of 180 GPa. The dense pressure coverage our volume data allows us to directly derive bulk modulus for over entire range. Our document major changes comp...
