Jewelry, such as bracelets, watches, and rings, could fall into food, creating a physical hazard. Jewelry should never be worn when working with food for these reasons. Employees, however, may wear a plain metal ring, such as a wedding band.
I'm football when a team is on the defense they often go into a formation known as zone. When in this formation, each player covers a certain area. This way instead of having to cover a specific player, they have the ability to cover multiple players of the opposing team, point them out to their teammates, and better predict where/how the opposing team will move or what they plan to do. Although this isn't the most effective position for protecting from runs, it is very effective at protecting from passes. This is because when in zone formation, the defense is mostly playing the field, meaning they are almost all in the field preventing the Quarterback from making effective passing plays.
Answer:
The correct answer is - Changing PRF.
Explanation:
Pulsed wave Doppler uses the principle of Doppler effect that objects that move changes the characteristic of sound waves. It is creates images by sending the short and quick pulses of the sound, it helps in the determining the velocity of blood in a exact time and location.
PRF or pulse repetition frequencies, is a Doppler sampling frequency that can affect the acoustic exposure of the scanning. PRF is measured in KHz.
Thus, the correct answer is - changing PRF.
