On longer timescales they may be both sources and sinks – during ice ages levels decrease to ~ 180 ppmv, and much of this is believed to be stored in the oceans.

As ice ages end, is released from the oceans and levels during previous interglacials have been around ~ 280 ppmv.

** Anomalous dynamics ( Random walk # Anomalous diffusion ), the stochastic motion of objects with mean squared displacement ( MSD ) that deviates from the relation for normal dynamics, MSD ~ t, where t is the time the process is seen ; anomalous dynamics are either faster than normal dynamics ( MSD > t ) or slower ( MSD < t )

** Brownian dynamics, the occurrence of Langevin dynamics in the motion of particles in solution ( e. g. a grain in water, as was first seen by Brown ); its famous property is: MSD ~ t, where MSD is the mean squared displacement, and t is the time the process is seen

** Normal dynamics, is a stochastic motion having a Gaussian probability density function in position with variance MSD that follows, MSD ~ t, where MSD is the mean squared displacement of the process, and t is the time the process is seen ( normal dynamics and Brownian dynamics are very similar ; the term used depends on the field )

The baseline length, that is, the Master-Slave distance, was typically 60 ~ 120 nautical miles.

This is huge when compared to normal renal sodium reabsorption which leaves only ~ 0. 4 % of filtered sodium in the urine.

Although various notations are used throughout the literature to denote that two elements a and b of a set are equivalent with respect to an equivalence relation R, the most common are " a ~ b " and " a ≡ b ", which are used when R is the obvious relation being referenced, and variations of " a ~< sub > R </ sub > b ", " a ≡< sub > R </ sub > b ", or " aRb ".

A given binary relation ~ on a set A is said to be an equivalence relation if and only if it is reflexive, symmetric and transitive.

A together with the relation ~ is called a setoid.

If ~ is an equivalence relation on X, and P ( x ) is a property of elements of X, such that whenever x ~ y, P ( x ) is true if P ( y ) is true, then the property P is said to be well-defined or a class invariant under the relation ~.

If ~ and ≈ are two equivalence relations on the same set S, and a ~ b implies a ≈ b for all a, b ∈ S, then ≈ is said to be a coarser relation than ~, and ~ is a finer relation than ≈.

* ~ is finer than ≈ if the partition created by ~ is a refinement of the partition created by ≈.

With longer sets ( more than ~ 40 people ) this would require long enough sets that the caller will usually only run the dance all the way around on ( rare ) non equal-turn dances.

By running DNA through an EtBr-treated gel and visualizing it with UV light, any band containing more than ~ 20 ng DNA becomes distinctly visible.

With a bulk modulus of about 27 MPa it is ~ 100 times more compressible than water.

The most common small fragments, however, are composed of 90 % helium-4 nuclei with more energy than alpha particles from alpha decay ( so-called " long range alphas " at ~ 16 MeV ), plus helium-6 nuclei, and tritons ( the nuclei of tritium ).

The latter figure means that a nuclear fission explosion or criticality accident emits about 3. 5 % of its energy as gamma rays, less than 2. 5 % of its energy as fast neutrons ( total ~ 6 %), and the rest as kinetic energy of fission fragments ( this appears almost immediately when the fragments impact surrounding matter, as simple heat ).

The declared weight of the 968CS is 1320 kg, ~ 100 kg lighter than the regular 968.

** A faster, fully hardware-based multiplier makes instructions such as MUL and IMUL several times as fast ( and more predictable ) than in the 80486 ; the execution time is reduced from 13 ~ 42 clock cycles down to 10 ~ 11 for 32-bit operands.

In the overall gloom, the pupil expands from ~ 2 mm to ~ 6 mm, and each retinal cell exposed to the solar image receives about ten times more light than it would looking at the non-eclipsed Sun.

Malay fertility-rate is ~ 70 % higher than Chinese and Indians.

Because the compression of each stage is ~ 10, each stage closer to the outlet is considerably smaller than the preceding inlet stages.

* 11 million km < sup > 2 </ sup > — Europe ( although Areas smaller than 10 million square kilometers gives the area for Europe as ~ 9 million km, and Europe gives the area for Europe as ~ 10 million km )

Typical numbers are ( when the incident particle is an electron ): ≈ 40 photons / keV for NaI ( Tl ), ~ 10 photons / keV for plastic scintillators, and ~ 4 photons / keV for bismuth germanate ( BGO ).

With and being constants, ~, i. e., ~, where ≈ 1. 5.

* if a ~ b then b ~ a.

* if a ~ b and b ~ c then a ~ c. ( Transitivity )

Reflexivity follows from symmetry and transitivity if for every element a ∈ A, there exists another element b ∈ A such that a ~ b holds.

Transitive and symmetric imply reflexive if and only if for all a ∈ X, there exists a b ∈ X such that a ~ b.

A frequent particular case occurs when f is a function from X to another set Y ; if x < sub > 1 </ sub > ~ x < sub > 2 </ sub > implies f ( x < sub > 1 </ sub >) = f ( x < sub > 2 </ sub >) then f is said to be a morphism for ~, a class invariant under ~, or simply invariant under ~.

This yields a convenient way of generating an equivalence relation: given any binary relation R on X, the equivalence relation generated by R is the smallest equivalence relation containing R. Concretely, R generates the equivalence relation a ~ b if and only if there exist elements x < sub > 1 </ sub >, x < sub > 2 </ sub >, ..., x < sub > n </ sub > in X such that a

The objects are the elements of G, and for any two elements x and y of G, there exists a unique morphism from x to y if and only if x ~ y.

* For any two elements x and y in X, there is a single morphism from x to y if and only if x ~ y.

Given a preorder on S one may define an equivalence relation ~ on S such that a ~ b if and only if a b and b a.

In cultured cells, the assembly of a CCV takes ~ 1min, and several hundred to a thousand or more can form every minute.

Examples of such environmental modifications include using the bed for sleep or sex only, not for activities such as reading or watching television ; waking up at the same time every morning, including on weekends ; going to bed only when sleepy and when there is a high likelihood that sleep will occur ; leaving the bed and beginning an activity in another location if sleep does not result in a reasonably brief period of time after getting into bed ( commonly ~ 20 min ); reducing the subjective effort and energy expended trying to fall asleep ; avoiding exposure to bright light during nighttime hours, and eliminating daytime naps.

A theory is ω-consistent if it is not ω-inconsistent, and is ω-inconsistent if there is a predicate P such that for every specific natural number n the theory proves ~ P ( n ), and yet the theory also proves that there exists a natural number n such that P ( n ).

Thus, a small molecule that can penetrate every corner of the pore system of the stationary phase " sees " the entire pore volume and the interparticle volume, and will elute late ( when the pore-and interparticle volume has passed through the column ~ 80 % of the column volume ).

The exchange takes place about once every four years ; the last close approaches occurred on January 21, 2006, and in 2010, when Janus's orbital radius increased by ~ 20 km, while Epimetheus's decreased by ~ 80 km ; Janus's orbit is less affected because it is 4 times more massive than Epimetheus.

In mathematics, a reflexive relation is a binary relation on a set for which every element is related to itself, i. e., a relation ~ on S where x ~ x holds true for every x in S. For example, ~ could be " is equal to ".

Every year, TG attracts more than ~ 5200 ( mostly young ) people, and the demand seems to be times higher every year.

For instance, for any two sentences A, B, A & B is satisfied if and only if A and B are satisfied ( where '&' stands for conjunction ), for any sentence A, ~ A is satisfied if and only if A fails to be satisfied, and for any open sentence A where x is free in A, ( x ) A is satisfied if and only if for every substitution of an item of the domain for x yielding A *, A * is satisfied.

Great Conjunctions take place regularly, every 18 – 20 years, as a result of the combined ~ 12-year orbital period of Jupiter around the Sun, and Saturn's ~ 30-year orbital period.
