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
The aorta is the largest artery and is connected directly to the heart. When blood flows from the heart and is forced into the arteries, they must expand to accept the blood and then contract to squeeze the blood into the veins as the heart relaxes between beats. This means that arteries need to be elastic to keep expanding and contracting. When the heart relaxes, it is the job of the arteries to maintain blood pressure and keep it moving forward. Arteries maintain the minimum needs of blood pressure. If they did not work, blood pressure would be closer to 120/0 instead of 120/80.
