In this work, we have devised a new approach to measure the critical pressure that a liquid marble can withstand. A liquid marble is gradually squeezed under a mechanical compression applied by two parallel plates. It ruptures at a sufficiently large applied pressure. Combining the force measurement and the high-speed imaging, we can determine the critical pressure that ruptures the liquid marb...

Knowledge of central venous pressure (CVP) is considered valuable in the assessment and treatment of various states of critical illness and injury. We tested a noninvasive means of determining CVP (NICVP) by monitoring upper arm blood flow changes in response to externally applied circumferential pressure to the upper arm veins. Thirty-six patients who were undergoing CVP monitoring as part of ...

The ground reaction curve (GRC) is a vital component of the convergence-confinement method, which possesses many applications in the underground space designs. It defines a relation between the tunnel wall deformations and the ground pressure acting on the tunnel walls. Generally, GRC includes descending and ascending branches. According to many researchers, the descending branch trend for the ...

Upper airway critical pressure measurements correlate with the degree of upper airway obstruction during sleep and may have a role in the diagnosis and treatment of obstructive sleep apnea. Nevertheless, the utility of the critical pressure has not yet been realized in the clinical setting because significant technical expertise is still required for the acquisition and analysis of pressure-flo...

in this survey, 55 patients were studied in a period of six years for having the anesthesia in the sitting position. in this position, the surgeon will had a better access to the location, whose damages have been sustained, so less damages would be given to the healthy tissues. for the patients, due to their critical general conditions, one week prior to giving anesthesia to the posterior fossa...

Selection of any superconducting material for practical applications highly depends upon different critical parameters like critical temperature (Tc), critical current density (Jc) and critical magnetic field (Hc). Different phases of Cu0.5Tl0.5Ba2Can− 1CunO2n+4−δ high temperature superconductor (HTSCs) family can be synthesized at higher pressure of (~5 GPa) as well as at ambient pressure[1]. ...
