2) Abdominal aorta catheters inflated the aorta, while digital microscopic images were recorded at stepwise pressures to measure arterial diameter and distensibility.
The existence of softer coal seams retards upward fracture growth, with a stepwise injection pressure associated with the discontinuous upward growth.
Aortic distensibility, the increase in external diameter during stepwise internal pressure increases, is also shown in figure 6.
In the DPA, cell separation is achieved by pulling iteratively on the cells while increasing stepwise the pressure in the micropipettes.
The liquid phase hydrogenation of 1,5,9-c,t,t-cyclo-dodecatriene (CDT) and of cyclododecadienes (CDD) towards cyclo-dodecene (CDE) using a Pd/Al2O3 catalyst of egg-shell type has been studied in discontinuous operation at different hydrogen pressures and for stepwise reduced hydrogen pressure.
A period of CMV was followed by stepwise reduction in pressure support.
Arterial segments were then submitted to a stepwise increase in pressure (10 to 150 mmHg) in order to determine arterial passive diameter [ 18].
Because we aimed at the highest Qb and filtration rates, we had to increase and reduce flow rates stepwise according to pressure thresholds, including the use of a filtration pump to generate equal net filtration rates comparably between the study groups.
