Repulsion of the Futsal Ball Depending on the Pressure in it [PDF]

Sport Mont, 2018
The aim of this research is to determine the elastic (repulsive) properties of the futsal ball depending on the air pressure in it. Futsal ball of standard dimensions was released on the fl at solid surface from the height of nine meters for four times.

Measurement of tensile strength of well cement sheath in underground gas storage based on tensile failure method

Engineering Reports
During gas injection in gas storage, the inner pressure increase, potentially leading to tensile failure of the cement sheath. At present, the fracture strength of cement stone is measured using the Brazilian splitting method (BSM), which is prone to ...

Fluid-solid coupling model and biological features of large vestibular aqueduct syndrome

Frontiers in Bioengineering and Biotechnology, 2023
Objective: Computed tomography (CT) images of the temporal bone of large vestibular aqueduct syndrome (LVAS) patients were used to establish 3D numerical models based on the structure of the inner ear, which are, in turn, used to construct inner ear ...

Iron silicides at pressures of the Earth's inner core [PDF]

Geophysical Research Letters, 2010
The Earth's core is expected to contain around 10 wt % light elements (S, Si, O, possibly C, H, etc.) alloyed with Fe and Ni. Very little is known about these alloys at pressures and temperatures of the core. Here, using the evolutionary crystal structure prediction methodology, we investigate Fe‐Si compounds at pressures of up to 400 GPa, i.e ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Detecting Intralabyrinthine Pressure Increase by Postural Manipulation with Wideband Tympanometry and Distortion Product Otoacoustic Emissions

Turkish Archives of Otorhinolaryngology, 2020
Objective: Intracranial pressure increase is known to affect inner ear pressure through the cochlear and vestibular aqueducts. This finding forms a good model for inner ear pressure studies.

Tunable adhesion of an elastic pillar by pressurizing inner cavity

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2021
This work studies the effect of a cavity with inner pressure on the adhesion of circular pillars with a flat tip in contact with a rigid smooth surface. The inner cavity of pillars is pressurized positively before the contact. The effect of the cavity on the adhesion is examined for different cavity diameters and different membrane thicknesses over the

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Proposed hydrogen kagome metal with charge density wave state and enhanced superconductivity

npj Computational Materials
The d-transition kagome metals provide a novel platform for exploring correlated superconducting state intertwined with charge ordering. However, the force of charge-density-wave (CDW) and superconductivity (SC) formation, and the mechanism underlying ...
