rate of decay

decay rate

1. At a given frequency, the rate at which the sound level in a room decreases after a source stops emitting sound; expressed in decibels per second (dB/s).
2. Of sound waves in an enclosed space, the rate at which the sound-pressure level of reverberation decreases; usually expressed in decibels per second.
3. Of a vibrating mechanical system, the rate at which some stated characteristic (such as the amplitude of vibration) decreases with time.

Experimenting with different combinations of materials for durability, rate of decay, and function, the artifacts in the Aguahoja Hex series are fabricated out of cellulose from trees, chitosan from crustaceans, acetic acid from apples, and glycerin.
Many times, the causes are improper brushing or dietary habits; however, there have been cases where the cause for tooth decay is genetics." The region with the highest rate of decay is Musandam, with 95 per cent of children in first and second grades suffering from cavities, while Muscat has the lowest rate of tooth decay in six- to eight-year olds, with 79 per cent.
423-424, studying the power function is of importance to be able to evaluate the performance of the test especially their rate of decay to a.
Recently, more complete results concerning the stability and the sharpness of the rate of decay of periodic solutions were obtained by Chen and Li in [8, 9].
Note the rate of decay to expiration is not linear but rather geometric.
The rate of decay of radioactive material on Earth may be affected by neutrinos emitted by the sun, according to (http://link.springer.com/article/10.1007/s11207-016-1008-9) a study published in the November edition of the journal Solar Physics.
The role of the stain is primarily aesthetic, to protect the surface of the wood from weathering; however, it may also potentially slow the rate of decay. The present study compares the decay resistance of stained and unstained decking.
He also showed that the classical solutions tend to equilibrium as t tends to infinity; however, no rate of decay has been discussed.
