Yes, a magnetic resonance imaging scanner uses an RF pulse to excite nuclei in the body.
Practically all medical MRI scanners are tuned to excite hydrogen nuclei.
Other MRI scanners used in physics and chemistry labs are tuned to excite other nuclei -- see the links for a detailed list.
The neck pulse is the corotid pulse; the wrist pulse is the radial pulse; the arm pulse is the brachial pulse. it seems that the pulses are named according to the artery palpated; therefore, your thumb pulse must be your princeps pollicis pulse. this is an educated guess.
Rf = distance to color/distance to front line
Rf value indicates the relationship of the distance moved by a pigment to the distance moved by a solvent.The Rf can be calculated by the following equation. Rf=distance pigment migrated/distance solvent front migrated.
Zero
I was very excited when I got a puppy for Christmas.
He was excited and tired and his pulse throbbed.

Background: PRI = Pulse Rate Interval. PRI is a term used in Radio Frequency (RF) systems. Specifically, Pulse mode RF systems, as apposed to continuous wave (CW) systems. Each pulse has an on period, pulse width (PW), and an off period. PRI is the time from the start of one pulse to the start of the next pulse. For example, if a pulse on time is 10 microseconds (uSec) and the off time is 90 uSec then the PRI is 100 uSec. Answer: A staggered PRI does not have a constant on and off time. The off time varies.
False
It goes up and down, as you become active or inactive, excited or calmed.
yes because it's certain types of television shows,and movies that you watch and you may get excited and pulse might start at a normal level,and when you get scared then it could get faster,or something.
An RF scale is a Representative Fraction (RF) Scale
What is rf transmitter
wt is RF SURVEY?
Rf is about .45
There are 3 main types of digital pulse modulation:Pulse time modulation (PTM), somewhat similar to analog phase modulation.Pulse width modulation (PWM), the width of the pulse represents the signal.Pulse code modulation (PCM), serial transmission of binary bits forming numeric or character codes that represent the signal.All of these can be modulated on an RF carrier using any of the standard modulation techniques: AM, FM, Phase Modulation, etc. One advantage with AM digital pulse modulation techniques over AM analog is that the carrier can be 100% modulated, which cannot be done with analog, thereby allowing significant reductions in transmitter power without loss of coverage range. Sometimes FM digital pulse modulation techniques are referred to as Frequency Shift Keying (FSK). A very complex method of combining Phase Modulation and AM to increase the bit density of digital pulse modulation on an RF carrier is called Quadrature Amplitude Modulation (QAM).
Your pulse rate could become higher due to taking excercise, becoming excited or scared. If it is persistant however, it could be a symptom of heart disease, thyroid malfunction or emphysema, amongst other things. Get checked out!
