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 influence of lumen diameter on resistance is dramatic: A slight increase or decrease in diameter causes a huge decrease or increase in resistance. This is because resistance is inversely proportional to the radius of the blood vessel (one-half of the vesselâs diameter) raised to the fourth power (R = 1/r4). This means, for example, that if an artery or arteriole constricts to one-half of its original radius, the resistance to flow will increase 16 times.
