	Shock wave
		Shock waves are not sound waves; a shock wave takes the form of a very sharp change in the gas properties on the order of micro-meters in thickness.
		This shock appears is generally generated by the interaction of two bodies of gas at different pressure, with a shock wave propagating into the lower pressure gas, and an expansion wave propagating into the higher pressure gas.
		The shock is the result of the deceleration of the gas by a converging duct, or by the growth of the boundary layer on the wall of a parallel duct.

	Shock wave Summary
		Shock waves are characterized by a sudden change in the characteristics of the medium (such as pressure, temperature, or speed) as a positive step function.
		A shock wave compression results in a loss of total pressure, meaning that it is a less efficient method of compressing gases for some purposes, for instance in the intake of a scramjet.
		Shock waves are not sound waves; a shock wave takes the form of a very sharp change in the gas properties on the order of a few mean free paths (roughly micro-meters at atmospheric conditions) in thickness.

	Extracorporeal Shock Wave Therapy ESWT for Heel Spurs and Plantar Fasciitis
		Efficacy and safety of extracorporeal shock wave therapy (ESWT) were investigated in 36 patients with chronic lateral epicondylitis--9 patients receiving and 27 patients not receiving worker's compensation.
		Shock wave therapy is quickly becoming a mainstay treatment for chronic recalcitrant plantar fasciitis, and many more applications for this therapy may exist.
		The current study showed that the directed application of electrohydraulic-generated shock waves to the insertion of the plantar fascia onto the calcaneus is a safe and effective nonsurgical method for treating chronic, recalcitrant heel pain syndrome that has been present for at least 6 months and has been refractory to other commonly used nonoperative therapies.

	shockwaves - scientific
		Acoustical shock waves were introduced in medicine for kidney stone lithotripsy in the early 1980's.
		Shock waves are the result of phenomena that create intense changes in pressure such as explosion, lightning, or supersonic aircraft.
		The shock wave is then reflected from the inside wall of a metal ellipsoid to create a focal point of shock wave energy in the target tissue.

	Shock Wave (Site not responding. Last check: 2007-11-07)
		Shock waves differ from sound waves in that the wave front, in which compression takes place, is a region of sudden and violent change in stress, density, and temperature.
		In particular, shock waves travel faster than sound, and their speed increases as the amplitude is raised; but the intensity of a shock wave also decreases faster than does that of a sound wave, because some of the energy of the shock wave is expended to heat the medium in which it travels.
		Shock waves alter the mechanical, electrical, and thermal properties of solids and, thus, can be used to study the equation of state (a relation between pressure, temperature, and volume) of any material.

	Aerodynamics, Acoustics, Shock Waves Propagation
		Shock waves are equivalent to acoustic waves in the limit of vanishing strength.
		Wave propagation is limited by the walls, and is generally one-dimensional (except for those cases in which the walls interact elastically with the waves).
		Acoustic waves propagate at a constant speed, and the flow of acoustic energy is independent of the duct section (contrary to the progagation of a blast).

	Oblique Shock Waves
		Shock waves are very small regions in the gas where the gas properties change by a large amount.
		Because a shock wave does no work, and there is no heat addition, the total enthalpy and the total temperature are constant.
		But because the flow is non-isentropic, the total pressure downstream of the shock is always less than the total pressure upstream of the shock; there is a loss of total pressure associated with a shock wave.

	Alert about side effects of shock wave lithotripsy (Site not responding. Last check: 2007-11-07)
		Mayo Clinic researchers are sounding an alert about side effects of shock wave lithotripsy: in a research study, they found this common treatment for kidney stones to significantly increase the risk for diabetes and hypertension later in life.
		Risk for diabetes was related to the intensity of the treatment and quantity of the shock waves administered; hypertension was related to treatment of stones in both kidneys.
		Shock wave lithotripsy uses shock waves to break up an impassable kidney stone into smaller, sandlike pieces which can be passed spontaneously, usually within a month.

	Shock Wave
		In the high-pressure shock tube shock waves are generated by filling the driver section with helium until the diaphragm separating the driver and driven sections ruptures.
		When the shock wave reaches the end of the driven section it is reflected and travels back towards the driver section and causes a second heating event.
		The time taken to alter the properties from those ahead of the shock wave to those behind the shock wave is approximately the time it takes for the head of the shock wave to traverse a distance equivalent to the thickness of the shock front i.e.

	Shocking Evidence for Cosmic Rays Found - Space - RedOrbit (Site not responding. Last check: 2007-11-07)
		The report by Hughes and colleagues demonstrates that the shock wave produced by the explosive disruption of the star behaves in a way that cannot be explained by the standard theory.
		These shock waves, analogous to the sonic boom produced by supersonic motion of an airplanes, produce sudden, large changes in pressure, and temperature behind the wave.
		A large component of cosmic ray nuclei alters the dynamics of the shock wave, and may require changing the way that astronomers estimate the explosive energy of a supernova from the properties of its remnant.

	shock wave therapy \| extracorporeal shock wave therapy
		The effectiveness of extracorporeal shock wave therapy was recently described in a paper presented at the Annual Meeting of the American College of Foot and Ankle Surgeons in New Orleans on February 8, 2001 (http://www.acfas.org/prshckwavthera.
		Amazingly, normal-weight and moderately obese patients reported that their chronic-plantar-fasciitis pain had dropped to zero the day after shock wave therapy (pain was rated on a scale from zero to five, with five representing the most intense-possible discomfort), and even severely obese individuals detected a drop-off in pain.
		Not surprisingly, extracorporeal shock wave therapy has also been used to treat tennis players suffering from tennis elbow, a condition in which the elbow of the arm holding the racquet becomes inflamed, painful, and stiff.

	Shock Wave Therapy Can Help Promote Bone Healing and Reduce Pain - TheHorse.com
		Shock wave therapy is a treatment that is increasingly used by veterinarians to treat orthopedic problems such as bone fractures and navicular disease.
		Contrary to what its name implies, shock wave therapy does not use electrical pulses, but rather high-energy acoustic pulses, much like sound waves, that have the ability to travel readily through soft tissues to effect hard material and tissues such as mineralized deposits or bone.
		Shock wave therapy was originally used in veterinary medicine to break up kidney stones.
