The calculation formula is: Rate Pressure Product (RPP) = Heart Rate (HR) * Systolic Blood Pressure (SBP) The units for the Heart Rate are beats per minute and for the Blood Pressure mmHg. Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial ...
A catalyst is a substance that alters the rate of a chemical reaction but it remains chemically unchanged afterwards. The catalyst increases the rate of the reaction by providing a new reaction mechanism to occur with in a lower activation energy. In autocatalysis a reaction product is itself a catalyst for that reaction leading to positive ...
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
The Federal Reserve kept its thumb squarely on the pause button at this week’s meeting. That’s good news for your bank accounts, since another rate cut would probably mean a lower return on ...

ECB President Christine Lagarde noted on Thursday that renewed trade tensions could even put more pressure on lagging euro zone growth, a potential argument for even lower rates in the 20-nation bloc.
That’s particularly true for products tied to the prime rate, an index that’s based on the federal funds rate. Almost all credit cards in the U.S. have variable interest rates tied to the ...
In vitro, they dilate the coronary and peripheral arteries and have negative inotropic and chronotropic effects - decreasing afterload, improving myocardial efficiency, reducing heart rate and improving coronary blood flow. In vivo, the vasodilation and hypotension trigger the baroreceptor reflex. Therefore, the net effect is the interplay of ...
