Plantar pressure gradient and pressure gradient angle are affected by inner pressure of air insole [PDF]

Frontiers in Bioengineering and Biotechnology
Clinically, air insoles may be applied to shoes to decrease plantar pressure gradient (PPG) and increase plantar gradient angle (PGA) to reduce foot ulcers. PPG and PGA may cause skin breakdown.

Turbulence Structures in Accelerated Flow over a Flat Plate with Non-Zero Pressure Gradient [PDF]

Journal of Applied Fluid Mechanics, 2022
The numerical simulation of temporally accelerated flow subjected to Favorable and Adverse Pressure Gradients (FPG & APG) is represented. Two accelerations are considered and imposed on fully turbulent flow over a flat plate.

Correlation of pressure gradient in three hepatic veins with portal pressure gradient

World Journal of Clinical Cases, 2022
The liver is one of the most important organs in the human body, with functions such as detoxification, digestion, and blood coagulation. In terms of vascular anatomy, the liver is divided into the left and the right liver by the main portal vein, and there are three hepatic efferent veins (right, middle, and left) and two portal branches.
