* Counts per minute

Counts per minute ( cpm ) is a measure of the detection rate of ionisation events due to radioactivity.

Counts per minute are only manifested in the reading of the measuring instrument, and are not an absolute measure of the strength of the source of radiation, which would be expressed in becquerels.

Counts per second ( cps ) is used for measurements when higher count rates are being encountered, or if hand held radiation survey instruments instruments are being used which are subject to faster rate changes when the instrument is moved over the survey area.

Commonly used for storing uncompressed ( PCM ), CD-quality sound files, which means that they can be large in size — around 10 MB per minute.

Freeware software such as Rapid Evolution can detect the beats per minute and determine the percent BPM difference between songs.

General Edmund Allenby used infantry, to successfully attack the strong Ottoman front line, under cover of an artillery barrage. This creeping barrage lifted and moved forward at a rate of between 50 yards ( 46 m ), 75 yards ( 69 m ) and 100 yards ( 91 m ) per minute, while 4. 5-inch howitzers fired on points beyond the barrage augmented by the guns of two destroyers firing from the Mediterranean Sea.

Operators had to maintain a steady rhythm, and the usual speed of operation was 30 words per minute.

However, printers are generally slow devices ( 30 pages per minute is considered fast, and many inexpensive consumer printers are far slower than that ), and the cost per page is actually relatively high.

More modern printers are measured in pages per minute.

Usually pages per minute refers to sparse monochrome office documents, rather than dense pictures which usually print much more slowly, especially colour images.

Bradycardia (; Greek βραδυκαρδία, bradykardía, " heart slowness "), in the context of adult medicine, is the resting heart rate of under 60 beats per minute, though it is seldom symptomatic until the rate drops below 50 beats / min.

Trained athletes or young healthy individuals may also have a slow resting heart rate ( e. g. professional cyclist Miguel Indurain had a resting heart rate of 28 beats per minute ).

The term relative bradycardia is used in explaining a heart rate which, although not actually below 60 beats per minute, is still considered too slow for the individual's current medical condition.

Bradycardia in an adult is any heart rate less than 60 beats per minute ( bpm ), although symptoms usually manifest only for heart rates less than 50.

Despite its difficulty of learning, this method remains popular in Chinese communities that use traditional Chinese characters, such as Hong Kong and Taiwan ; it is also the first method that allowed users to enter more than a hundred Chinese characters per minute.

Most users report a typing speed of fifty characters per minute, though some reach over one hundred per minute.

Temperatures between 600 and 650 ° C and pressures between 25 and 150 Pa yield a growth rate between 10 and 20 nm per minute.

Many stenotype users can reach 300 words per minute.

If Af is the change per unit volume in Gibbs function caused by the shear field at constant P and T, and **yr is the density of the fluid, then the total potential energy of the system above the reference height is Af.

It is assumed that the flux values increase by a factor of 2.512 per magnitude, in accordance with the opinion that the total mass flux in each unit range in magnitude is constant.

The high cost of land and a few operational problems resulting from excessive loadings have created the need for a wastewater treatment system with the operational characteristics of the oxidation pond but with the ability to treat more organic matter per unit volume.

Mines need to be recognized as a major element in anti-submarine warfare employment, extended to deep water, and have their effective area per unit increased.

In 1961, it is estimated that multiple unit dwellings will account for nearly 30 per cent of the starts in residential construction.

In practical terms, the ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6. 241 × 10 < sup > 18 </ sup > electrons, or one coulomb per second constituting one ampere.

In this way, amperes can be viewed as a flow rate, i. e. number of particles ( charged ) transiting per unit time, and coulombs simply as the number of particles.

The ampere was originally defined as one tenth of the CGS system electromagnetic unit of current ( now known as the abampere ), the amount of current that generates a force of two dynes per centimetre of length between two wires one centimetre apart.

Once a movement per unit time is observed, astronomers compensate for the parallax caused by the earth ’ s motion during this time and the heliocentric distance to this object is calculated.

As the speed of light in meters per second ( c < sub > 0 </ sub >) is fixed in the International System of Units, this measurement of the speed of light in AU / d ( c < sub > AU </ sub >) also determines the value of the astronomical unit in meters ( A ):
