Dr. Charles Munroe discovered that when a block of guncotton was detonated with its lettered surface against a steel surface, a mirror image of the letters were impressed into the steel.
Damage to the target is, however, not due to the perforation of the armor plate, but the effects of the jet escaping inside the target, the effects of the jet on the internal surface of the armor plate, and the effects of that portion of the slug that follows the jet into the target interior:
For hydrodynamic effects, molten armor solidifies to form metal droplets, which at speed have the effect of firing a small gauge shotgun shell inside the target.

 Meditation's Effect on the Brain
While Munroe initially tried meditation to manage her chronic pain on advice of a colleague, she soon learned that the program was having a profound impact on her general sense of well-being.
Munroe sees meditation as a way to raise a person's quality of life by learning to focus on what's important, and ignore fleeting and meaningless desires.
For patients like Munroe, who has learned to regain control of her life by gaining control of her pain, meditation is now a natural part of her daily existence.

 Misznay-Schardin effect - Wikipedia, the free encyclopedia
The Misznay-Schardin effect is a characteristic of the detonation of a broad sheet of explosive.
This effect was studied and experimented with by explosive experts Misznay, a Hungarian, and Dr. Hubert Schardin, a German, who initially sought to develop a more effective anti-tank mine for Nazi Germany.
The United States' Claymore mine relies on the Misznay-Schardin effect.

Munroe realised that the cavity in the explosive was focusing the blast.
The Munroe Effect was virtually forgotten until the invention of the tank, when it offered a novel way of breaking through armour.
Devices using the Munroe effect are called shaped charges, hollow charges or high explosive anti-tank (Heat) weapons.

Lindenmeyr/ Munroe challenged Dooley's ballot, contending that he was a supervisor within the meaning of Section 2(11).
And, of course, there is precedent to the effect that being the senior worker on an evening or night shift does not, ``ipso facto,'' categorize that person as a ``supervisor.'' NLRB v.
Because Thomas Toegemann was not then an employee of Lindenmeyr/ Munroe and thus not eligible to vote in the election, the challenge to Toegemann's ballot should be sustained.

 Taddle Creek Magazine | Steal This Logo | Interview by Kerri Huffman
Munroe’s book follows Sam Breen, a scrapper-turned-instructor, on an intergalactic adventure as he teaches English to a group of Octavians, a race of octopus-like aliens, on their home planet, Octavia, in 2959.
Munroe likens this to an experience he had while in Korea when, as a special treat at a school picnic, dozen of baby octopuses were cooked alive in a pan.
Despite Munroe’s ability to deal with political and moral issues deftly and lightly, there are moments when the reader does see dark sides of Sam—specifically in relation to his background as a “pug.” In the novel, pugs are a gang-like group that wanders the earth in search of physical violence.

 Jamaica Gleaner - Munroe wants Senate to support Labour Relations Code - Wednesday | November 1, 2000
He noted that the LRC requires employers, in so far as is consistent with operational efficiency, to consult with the workers or their representatives and take all reasonable steps to avoid redundancies.
Munroe's resolution also called on the Government and relevant organisations, such as the Jamaica Employer Feder-ation, to take the necessary steps to familiarise employers with the LRC and to ensure their observation of the Code.
Senator Munroe said this was necessary because some employers were violating the Code by "springing overnight redundancies on workers," among other things.

 Chapter 13 WARHEADS
Whereas the effects of an idealized blast payload are at-tenuated by a factor roughly equal to 1/R3 (R is measured from the origin), the attenuation of idealized fragmentation effects will vary as 1/R2 and 1/R, depending upon the specific design of the payload.
Dr. Charles Munroe, while working at the Naval Torpedo Station at Newport, Rhode Island, in the 1880s, discovered that if a block of guncotton with letters countersunk into its surface was det-onated with its lettered surface against a steel plate, the let-ters were indented into the surface of the steel.
As the detonation depth increases, particularly in excess of 180 feet, the effect of the gas bubble causing damage is greatly diminished; there-fore, bottom mines are rarely used in waters exceeding 180-200 feet.

 Munroe effect - Wikipedia, the free encyclopedia
The Munroe effect refers to the partial focusing of blast energy caused by a hollow or void cut into a piece of explosive, a property which is exploited by a shaped charge.
Whilst working at the Naval Torpedo Station at Newport in the United States, he noticed that when a block of guncotton with the manufacturer's name stamped into it was detonated next to a metal plate, the lettering was cut into the plate.
However, the military usefulness of this effect was not appreciated until the Second World War.

We also demonstrate different effects of the genetic assimilation process (Nolfi & Floreano, 1999) and their dependence on the variability of the language environment and its learning costs.
Two major parameters were varied to ascertain their effects on the type and strength of the Baldwin effect.
However, if the learning costs are low the effect is much reduced, as there is little evolutionary pressure to translate the lifetime learning task into genetic structures.

 Shaped Charges   (Site not responding. Last check: 2007-11-03)
Because the effect is independent from the kinetic energy of the warhead, it doesn't matter with which "carrier" the shaped charge is being brought onto the target; both target range and weapon velocity are not a factor, the charge can be literally laid onto the target and still have the same devastating effect.
The only variabels which effect the performance are the kind of explosive used, the shape of the hollow cone and the distance to the target surface at the moment of detonation.
This application of the Munroe Effect is enhanced by careful control of charge dimensions and configuration as well as liner and backer thickness and uniformity.

The NMR resonant frequency provides information about the molecular material in which the nuclei reside, and NMR is used in chemistry and physics to analyze samples of solids and liquids, as well as in medicine to analyze tissues removed from the body.
In the 18th century Charles Coulomb found that the magnetic forces of attraction and repulsion are directly proportional to the product of the strengths of the poles and inversely proportional to the square of the distances between them.
As with electric charges, the effect of this magnetic force acting at a distance is expressed in terms of a field of force.

In addition to completing the questionnaire, students were instructed to obtain samples from one of various locations around their residences and from various distances from the entrance and exit of the building.
Munroe reveals the importance of exploring such relationships when he asks us to consider that, "[p]oor, minority children in the inner cities, who are often already at a disadvantage by inadequate nutrition and other factors, are particularly vulnerable to lead poisoning."
Dr. Munroe notes that, "The results of the survey obtained to date will be further supplemented by a subsequent projects on environmental justice, in which a larger number of surveys [will be] utilized and a larger number of samples [will be] taken.

 Bang!
(Yes, that's the Munroe effect, just like in an anti-armor shaped charge.) Further complicating the set-up, the initiator itself can be levitated, and may have multiple concentric layers repeating the beryllium-nickel-polonium sequence.
This vaporization produces a reaction effect, forcing the outer layer (which may be a uranium tamper) inward.
Even though only a small portion of the energy from the primary actually heads in the direction of the secondary (and this is with design features which help concentrate the energy in that direction), that fraction is vastly greater than the energy of the explosives used to initiate a single-stage device.

The primary purpose of this sphere, called the "pusher", seems to have been to reduce the effect of the Taylor wave, the rapid drop in pressure the occurs behind a detonation front.
Due to the uncertainty in predicting yield, and the fact that bursting too high causes a rapid deterioration in effects, the burst height had been set conservatively low in case a low yield explosion occurred.
The cylindrical implosion design allowed the fusion experiment to be heated directly by the pit without the shielding effects of a high explosive layer, and avoided disruption by expanding detonation gases.

When the charge is detonated by the fuze mounted in the nose, a jet of high-energy gas and vaporised metal from the cone is projected axially forward (the Munroe effect).
However, if an exit hole in excess of 24 mm in diameter is produced, the terminal effect inside the vehicle is likely to be considerable as the jet continues into the target with considerable residual energy bringing with it 'spall' or splinters torn off the armour plate.
Thus, the performance and effect of the hollow charge round is largely dependent on cone diameter.

Limited experiments have shown that application of techniques similar to those used in shaped charge anti-tank weapons (the Munroe effect) can produce higher and larger fuel explosion effects, while using less fuel and explosive material, thereby creating a more controlled effect.
Significant advancements in the mechanisms and theory of combustion have increased the understanding of many effects and led to improved illuminants both theoretically and practically.
Effects of spin, liner thickness and binders have been analyzed, and application of the results has been used to improve illuminant performance and solve production problems.
