PLC Development Environment Using GX Developer. In the C64 Series, the user PLC development environment is supported using MELSEC PLC. development tool, which is Mitsubishi integrated FA software MELSOFT series (GX Developer). This manual explains system configurations user PLC development environment using GX.
Critical Closing Pressure, Laplaceâs Law and Compliance Critical closing pressure â Pressure at which a blood vessel collapses and blood flow stops Laplaceâs Law â Force acting on blood vessel wall is proportional to diameter of the vessel times blood pressure Vascular compliance â Tendency for blood vessel volume to increase as blood pressure increases â More easily the vessel wall stretches, the greater its compliance
When the heart contracts and forces  blood into the large arteries near the heart, they stretch to  accommodate the greater blood volume (systolâ¦ic pressure). Then, as  the blood continues on in the circuit, their walls recoil, keeping  pressure on the blood which keeps it moving (diastolic pressure).
