11. The extended hydrostaticity greatly reduces the pressure gradient in samples at high pressure. 12. Follow-up includes checking peripheral pulses and the arm-leg blood pressure gradient . 13. His larynx spasmed, and he had a severe pressure gradient in his lungs. 14. Phloem cells mainly transport sucrose along pressure gradients generated by osmosis. 15. The pressure gradient in an ultrasonic wave moves particles relative to the fluid. 16. The first term is the effect of perturbation pressure gradients on vertical motion. 17. The divergence theorem is applied to the advection, pressure gradient , and diffusion terms. 18. Hydrostatic and osmotic pressure gradients facilitate filtration across a semipermeable membrane. 19. Any pressure gradient greater in magnitude than this critical value will result in flow. 20. However, the pressure gradient field may also be of interest.
