The calcium content of phosphorus-containing foods may also matter, and may mitigate potential problems. In fact, dairy foods (high in both phosphorus and calcium) lower blood pressure, which is why they are an integral part of the DASH (Dietary Approaches to Stop Hypertension) diet.he calcium content of phosphorus-containing foods may also matter, and may mitigate potential problems.

This originally pertained to radio waves and sound waves, but is now commonly used to measure the speed of a computer processor (the number of hertz is equal to the number of clock ticks that a processor will have in one second).
These types of instruments are used by the wind energy industry, both for wind resource assessment and turbine control. Wind speed is measured with an anemometer. In situations where modern instruments are not available, an index finger can be used to test the direction of wind. This is accomplished by wetting the finger and pointing it upwards. The side of the finger that feels cool is (approximately) the direction from which the wind is blowing.
