The majority of the clocks are caesium clocks ; the definition of the SI second is written in terms of caesium.

In the second example CH < sub > 3 </ sub > COOH undergoes the same transformation, in this case donating a proton to ammonia ( NH < sub > 3 </ sub >), but cannot be described using the Arrhenius definition of an acid because the reaction does not produce hydronium.

The practical definition may lead to confusion with the definition of a coulomb ( i. e., 1 amp-second ), but in practical terms this means that measures of a constant current ( e. g., the nominal flow of charge per second through a simple circuit ) will be defined in amperes ( e. g., " a 20 mA circuit ") and the flow of charge through a circuit over a period of time will be defined in coulombs ( e. g., " a variable-current circuit that flows a total of 10 coulombs over 5 seconds ").

Unfortunately in the literature the definition is given in two variants: Despite the fact that Bernoulli defined B < sub > 1 </ sub > = 1 / 2 ( now known as " second Bernoulli numbers "), some authors set B < sub > 1 </ sub > = − 1 / 2 (" first Bernoulli numbers ").

Whenever a confusion between the two kinds of definitions might arise it can be avoided by referring to the more general definition and by reintroducing the erased parameter: writing B < sub > m </ sub >( 0 ) in the first case and B < sub > m </ sub >( 1 ) in the second will unambiguously denote the value in question.

Although the candela is now defined in terms of the second ( an SI base unit ) and the watt ( a derived SI unit ), the candela remains a base unit of the SI system, by definition.

In 1967, a specific frequency from the emission spectrum of caesium-133 was chosen to be used in the definition of the second by the International System of Units.

Notice that the second condition in the definition itself refers to natural numbers, and hence involves self-reference.

This article uses the second definition and does not describe porpoises ( suborder Odontoceti, family Phocoenidae ).

The second law is then a consequence of this definition and the fundamental postulate of statistical mechanics.

Abramowitz and Stegun substitute the integral of the first kind,, for the argument in their definition of the integrals of the second and third kinds, unless this argument is followed by a backslash: i. e. for.

Following this, in 1967 / 68, the General Conference on Weights and Measures ( CGPM ) replaced the definition of the SI second by the following:

Although this is an independent definition that does not refer to the older basis of ephemeris time, it uses the same quantity as the value of the ephemeris second measured by the cesium clock in 1958.

In the context of this article, FTL is the transmission of information or matter faster than c, a constant equal to the speed of light in a vacuum, which is 299, 792, 458 meters per second ( by definition ) or about 186, 282. 4 miles per second.

However, the usage of Irish diaspora is generally not limited by citizenship status, thus leading to an estimated ( and fluctuating ) membership of up to 80 million persons — the second and more emotive definition.

This statement is equivalent to the first of the above-given definitions of the inverse, and it becomes equivalent to the second definition if Y coincides with the codomain of ƒ.

This statement is an obvious consequence of the deduction that for ƒ to be invertible it must be injective ( first definition of the inverse ) or bijective ( second definition ).

The defined dogma of the Immaculate Conception regards original sin only, saying that Mary was preserved from any stain ( in Latin, macula or labes, the second of these two synonymous words being the one used in the formal definition ).

A second definition given by Behe ( his " evolutionary definition ") is as follows:

However, a second definition and usage has historically been in practice in many fields of computer science and information technology, which defines the prefix kilo when used with byte or bit units of data as 1024 ( 2 < sup > 10 </ sup >); this is due to the mathematical coincidence that Thus, in these fields 1 kilobyte is equal to 1 kibibyte, a new unit standardized as part of the binary prefixes to resolve the ambiguity.

The simple passage of an additional eleven months' time makes the second 3% boost more acceptable.

* 1989 – Voyager 2 spacecraft makes its closest approach to Neptune, the second to last planet in the Solar System at the time.

The dealer's hand receives its first card face up, and in " hole card " games receives its second card face down immediately ( the hole card ), which the dealer peeks at but does not reveal unless it makes the dealer's hand a blackjack.

The first identifies the content of consciousness with the experiences that are reported by human subjects ; the second makes use of the concept of consciousness that has been developed by neurologists and other medical professionals who deal with patients whose behavior is impaired.

The second most common cause of coma, which makes up about 25 % of comatose patients, occurs from lack of oxygen, generally resulting from cardiac arrest.

'" Morris's second documentary would be about the town and bear its name, although it makes no mention of Vernon as " Nub City ", but instead explores other idiosyncrasies of the town's residents.

Equipment from the Soviet Union is being progressively replaced by more modern U. S., French, and British equipment, a significant portion of which is built under license in Egypt, such as the M1A1 Abrams tank which makes Egypt the owner of the second largest number of latest generation main battle tanks in the region after Israel, and the second after Syria in case of the older generations.

NASA World Wind ( open source ) is a second generation applet that makes heavy use of OpenGL and on-demand data downloading to provide a detailed 3D map of the world.

Hershel Parker in the second volume of his biography makes it clear that Melville became a nominal member only to placate his wife.

) Later writers describe his lameness as the consequence of his second fall, while Homer makes him lame and weak from his birth.

This principle differs from the special principle in two ways: first, it is restricted to mechanics, and second, it makes no mention of simplicity.

Leviticus rests in two crucial beliefs: the first, that the world was created " very good " and retains the capacity to achieve that state although it is vulnerable to sin and defilement ; the second, that the faithful enactment of ritual makes God's presence available, while ignoring or breaching it compromises the harmony between God and the world.

A second strand of Kaplanian theology exists, which makes clear that God has ontological reality, a real and absolute existence independent of human beliefs, while rejecting classical theism and any belief in miracles.

The second factor is that the energy of the transmitted pulse is spread over a wide frequency spectrum, which makes necessary its receiver to have a corresponding wide selectivity.

This makes it the tallest mountain on any planet in the Solar System ( and, after the 2011 discovery of Rheasilvia Mons on 4 Vesta, the second largest mountain on any world known to man ).

His reasoning for this is twofold: First, a failed check-raise gives other players the chance to see free cards that may improve their hand ; second, it makes it obvious to other players that you potentially have a very strong hand.

The Liber Pontificalis also presents a list that makes Linus the second in the line of bishops of Rome, after Peter ; but at the same time it states that Peter ordained two bishops, Linus and Cletus, for the priestly service of the community, devoting himself instead to prayer and preaching, and that it was to Clement that he entrusted the Church as a whole, appointing him as his successor.
