So, normally I would start at 38 beats per minute, and while holding my breath it would drop to 12 beats per minute, which is pretty unusual.

A krypton fluoride laser (KrF laser) is a particular type of excimer laser, which is sometimes (more correctly) called an exciplex laser.

A toddler's heart will beat about 100 120 times per minute, an older child's heartbeat is around 60 100 beats per minute, adolescents around 80 100 beats per minute, and adults' pulse rate is anywhere between 50 and 80 beats per minute.

The projected lifetime of the artificial heart is around 5 years (230 million beats).

The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed (invented by Kumar Patel of Bell Labs in 1964), and is still one of the most useful.

It employs a technique known as collinear holography, whereby a green and red laser beam are collimated in a single beam.

He hesitated before answering.

E Laser noise SW Yeah, yeah. That was pretty funny, Einstein.

They are also used in conjunction with silicon to produce hybrid silicon lasers.

Female Voice Long range laser scanning by sending out a pulse that's a laser beam of light.

E Spaceship noise SW Even if it doesn't have a laser?

Usually, laser ablation refers to removing material with a pulsed laser, but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough.

So this robot is actually equipped with a camera and a laser rangefinder, laser scanner.

Metal ion lasers are gas lasers that generate deep ultraviolet wavelengths.

LC circuits are used either for generating signals at a particular frequency, or picking out a signal at a particular frequency from a more complex signal.

Acoustic resonance is the tendency of an acoustic system to amplify a frequency that matches one of its own natural frequencies of vibration (its resonance frequencies ).

A newborn or infant can have a heart rate of about 130 150 beats per minute.

Thin disk lasers have been shown to produce beams of up to one kilowatt.

For example it is used in the carbon dioxide laser, which is one of the earliest type of lasers.

The original black and white standard, with its 15750 Hz line frequency and 4.5 MHz audio subcarrier, does not meet these requirements, so designers had either to raise the audio subcarrier frequency or lower the line frequency.

Similar dithering is apparent at the geopolitical level as well.

After hesitating, Zardari arrived in London three days later.

The frequency is usually in the range 1 to 10 kHz.

This carrier wave is usually a much higher frequency than the input signal.

The one on the top right here is actually a dazzling laser intended to just blind the person momentarily and disorient them.

The design uses 192 beamlines in a parallel system of flashlamp pumped, neodymium doped phosphate glass lasers.

So the engineers chose the line frequency to be changed for the color standard.

Seeing that the Angel was an Eva, the pilots hesitated.

This is a pulse of light that's only about one wavelength of light long, so it's a whole bunch of photons all coming and hitting simultaneously.

So, there're lots of things. Everything has RF tags there's RF tags on the user, on the cards, there's the staff devices that are all around the store.

Lowering the line frequency is comparatively innocuous, because the horizontal and vertical synchronization information in the NTSC signal allows a receiver to tolerate a substantial amount of variation in the line frequency.

For example, the first working laser was a ruby laser, made from ruby (chromium doped corundum).

In case of a modem, this corresponds to 1,000 tones per second, and in case of a line code, this corresponds to 1,000 pulses per second.

What do you suggest? Ghassan attempted to speak as smoothly as he could muster.

There is also a hesitation in some rural areas to sending girls to school.

Radio frequency (RF) is a rate of oscillation in the range of around to , which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

Each pulse lasts a decade or more, and an amount of time on the order of 10,000 years passes between each pulse.

Any hesitation could have profound and irreparable consequences for him.

Newton had been reluctant to publish his calculus because he feared controversy and criticism.

and to those who were in Hebron, and to all the places where David himself and his men used to stay.

And to them which were in Hebron, and to all the places where David himself and his men were wont to haunt.

Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam.

And I have to explain to you, the top of this graph shows you that frequency distribution that I talked about.

It would be all atoms pulsating in unison, emitting light of one color, one frequency.

With governments hesitating to do their part, the ECB is reluctant to support them.
