put your finger on a pulse point, like the inside of your wrist, and count how many pulses you feel in a minute. that yields your heart’s beats per minute, or bpm. cool trick! you thought. and you promptly forgot about it. but your heart rate can be a useful piece of data. i...
But the most prominent gauge— and perhaps the most important, at least in terms of how many times you look at it while you're driving— is the speedometer. The job of the speedometer is to indicate the speed of your car in miles per hour, kilometers per hour or both. Analog ...
The light passing through each filter is detected by the photocell, where it is converted to an electrical pulse. The electrical pulse is relayed to the microprocessor, which interprets the pulses and calculates the BAC based on the absorption of infrared light. How the Alcosensor III or IV ...
It’s not clear how much Jeff Tremblay knows about the role he’s playing in a revolution in the treatment of the catastrophically brain injured
What is an average pulse rate? A normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm), according to The Mayo Clinic. Women tend to have a slightly higher heart rate than men; the average resting heart rate in women is in the mid-70s, while it is only ...
Trends are made of pulses and retracements in a zig-zag shape which are also called support and resistance levels. The support level is the price where traders are willing to buy an asset, while the resistance level is the price they are willing to sell. Older levels are more powerful ...
When the RF pulse is turned off, the hydrogen protons slowly return to their natural alignment within the magnetic field and release the energy absorbed from the RF pulses. When they do this, they give off a signal that the coils pick up and send to the computer system. But how is this...
That's almost 18 million times slower than normal! No one would have thought such a feat possible just a few years ago, yet this is the capricious way of light. Just when you think you have it figured out, it defies your efforts and seems to change its nature. Still, we've come a...
in the case of trapdoor or ring-faulting in response to pressurisation or depressurization of magmatic reservoirs and conduits. In many cases, however, we observe so-called quasi anti-repeaters, which have a reversed focal mechanism but occur on neighbouring structures. These earthquakes can be mo...
A normal resting heart rate (taken after about five minutes of inactivity) isbetween 60 and 100beats per second. The lower the number, the more fit you’re likely to be. Athletes or those in particularly good shape often have resting pulses below that 60 threshold. ...
