	Pulse - Wikipedia, the free encyclopedia
		The pulse results from pressure waves moving through the blood vessels, which are pliable; it is not caused by the forward movement of the blood.
		The pulse deficit (difference between heart beats and pulsations at the periphery) should be determined by simultaneous palpation at the radial artery and auscultation at the heart apex.
		The ease of palpability of a pulse is dictated by the patient's blood pressure.

		It may also supervene on the rupture of a gastric ulcer, and is then the result of the injury to which the network of nerves in the interior of the abdomen has been subjected by the sudden escape on to them of the contents of the stomach.
		In severe shock the patient is pale, and bathed in clammy perspiration; his sensibility is blunted; his pulse is small and weak, sometimes, indeed, it is imperceptible, and even on laying the hand over the heart no cardiac impulse may be felt.
		Shock is due to an impression conveyed to the medulla oblongata, by which the nerve-centres are so affected that a partial paralysis of the voluntary and involuntary muscular fibres in the body takes place, the patient being, perhaps, unable to lift his arm or move his leg.

	Glitch Did You Mean glitch (Site not responding. Last check: 2007-09-20)
		In electronics, a glitch is an electrical pulse of short duration that is usually the result of a fault or design error, particularly in a digital circuit.
		For example, many electronic components such as flip-flops are triggered by a pulse that must not be shorter than a specified minimum duration, otherwise the component may malfunction.
		A related concept is the runt pulse, a pulse whose amplitude is smaller than the minimum level specified for correct operation, and a spike, a short pulse similar to glitch but often caused by ringing or crosstalk.

	Nuclear Magnetic Resonance - Wikipedia
		This technique, known as Fourier transform NMR spectroscopy (FT-NMR), has been made more practical with the development of computers capable of performing the computationally-intensive mathematical transformation of the data from the time domain to the frequency domain, to produce a spectrum.
		At the end of the pulse, the nuclei relax back to their equilibrium state, emitting the energy absorbed by the system again in the radiofrequency range.
		The use of pulses of various shapes, frequencies, and durations, in specifically-designed patterns, gives the spectroscopist great flexibility in determining what portions of a molecule, or what intra- and intermolecular dynamic processes, to study.

		A pulse jet engine (or pulsejet) is a very simple form of internal combustion engine wherein the combustion occurs in pulses and the propulsive effort is a reaction to the rearward flow of hot gases.
		The valving is accomplished though the use of reed valves or, in a valveless pulse jet engine, through aerodynamics.
		For a small model-type engine the frequency may be typically around 250 pulses per second — whereas for a larger engine such as the one used on the German V1 flying bomb, the frequency was closer to 45 pulses per second.

		It was not until about the middle of 1943 that Bell Labs people who designed the sigsaly system, became aware of the use of PCM binary coding as already proposed by Alec Reeves.
		This perhaps is a natural consequence of this technique having evolved alongside two others, Pulse width modulation and Pulse position modulation, in which the information to be encoded is in fact represented by binary signal pulses of varying width or position, respectively.
		According to the Inventors Hall of Fame, B.M Oliver and Claude Shannon are the inventors of PCM as described in 'Communication System Employing Pulse Code Modulation,' US Patent Number 2,801,281 [1] filed in 1946 and 1952, granted in 1956.

		Pulses show a strong decrease in initial slope and overall magnitude during heterosynaptic depression.
		(Note that baseline measurements involved paired pulses that are plotted according to the time interval between the ipsilateral pulse and the later contralateral paired pulse.) Baseline measurements are also shown for long interval paired pulses where faciliation measurements were not obtained.
		This reduction in the relative amount of faciliation is consistent with the reduction in heterosynaptic depression caused by the antagonist.

		Q-switching, sometimes known as giant pulse formation, is a technique discovered circa 1962 by R.W. Hellwarth and F.J. McClung using electrically switched Kerr cell shutters and is a technique by which a laser can be made to produce a pulsed output beam.
		The technique allows the production of light pulses with extremely high (gigawatts) peak intensity, much higher than would be produced by the same laser if it were operating in a continuous wave (constant output) mode.

	Womens Flip Flops
		For other meanings, see flip-flop (disambiguation).'' In electronics and computing, the flip-flop or ''bistable multivibrator'' is a pulsed digital circuit capable of serving as a one-bit memory.
		(In actuality, flip-flops are implemented as integrated circuit chips that also require power and ground connections.) Pulsing, or ''strobing'', the clock causes the flip-flop to either change or retain its output signal, based upon the values of the input signals and the characteristic equation of the flip-flop.
		For other meanings, see flip-flop (disambiguation).'' In footwear and fashion, flip-flops are a kind of flat, backless sandal that consist of simple soles held on the foot by a V-shaped strap that passes between the toes and around either side of the foot, attached to the sole at three points.

		A laser (Light Amplification by Stimulated Emission of Radiation) is a device which uses a quantum mechanical effect, stimulated emission, to generate a coherent beam of light from a lasing medium of controlled purity, size, and shape.
		Later, in 1994, it was discovered by Mourou and his team at University of Michiganthat the balance between the self-focusing refraction (see Kerr effect) and self-attenuating diffraction by ionization and rarefaction of a laser beam of terawatt intensities in the atmosphere creates "filaments" which act as waveguides for the beam thus preventing divergence.
		It is usually operated in a pulsed mode, and passed through optical fiber surgical devices to resurface joints, remove rot from teeth, vaporize cancers, and pulverize kidney and gall stones.
