Proof that the Center of Buoyancy is Equal to the Center of Hydrostatic Pressure —Part 2 : Semi-Submerged Circular Cylinder and Triangular Prism— [PDF]

, 2023
We recently proved that “ the center of buoyancy of floating bodies is equal to the center of hydrostatic pressure". This subject was an unsolved problem in physics and naval architecture, even though the buoyancy taught by Archimedes' principle can be ...

Structural transitions of 4:1 methanol–ethanol mixture and silicone oil under high pressure

Matter and Radiation at Extremes, 2021
A 4:1 (volume ratio) methanol–ethanol (ME) mixture and silicone oil are two of the most widely used liquid pressure-transmitting media (PTM) in high-pressure studies.

Monitoring Of The Center Of Pressure In Unipedal Support In Karate

المجلة العلمية العلوم والتكنولوجية للنشاطات البدنية والرياضية, 2021
Stabilometry is a technique for analyzing posture based on recording the oscillations of a subject's center of pressure (COP) on an instrumented platform. Under unusual or destabilizing conditions, maintaining postural activity requires the establishment of rapid motor reactions.

Toughening of silicon nitride ceramics through stress-induced phase transformation

Journal of Advanced Ceramics
Ceramics, particularly covalently bonded ceramics, exhibit intrinsic brittleness resulting from the strong directional nature of their chemical bonds, significantly limiting their applications.

Synthesis of quenchable amorphous diamond

Nature Communications, 2017
Diamond’s properties are dictated by its crystalline, fully tetrahedrally bonded structure. Here authors synthesize a bulk sp 3-bonded amorphous form of carbon under high pressure and temperature, show that it has bulk modulus comparable to crystalline ...
