He also offers a conversion table ( see Cohen, 1988, p. 283 ) for eta squared ( η < sup > 2 </ sup >) where 0. 0099 constitutes a small effect, 0. 0588 a medium effect and 0. 1379 a large effect.

The two functors F and G are called naturally isomorphic if there exists a natural transformation from F to G such that η < sub > X </ sub > is an isomorphism for every object X in C.

* Statistics, η < sup > 2 </ sup > is the " partial regression coefficient ".

The general name metallocene is derived from ferrocene, ( C < sub > 5 </ sub > H < sub > 5 </ sub >)< sub > 2 </ sub > Fe or Cp < sub > 2 </ sub > Fe, systematically named bis ( η < sup > 5 </ sup >- cyclopentadienyl ) iron ( II ).

Using the nomenclature of " hapticity ", the equivalent bonding of all 5 carbon atoms of a cyclopentadienyl ring is denoted as η < sup > 5 </ sup >, pronounced " pentahapto.

Some metallocene complexes of actinides have been reported where there are three cyclopendadienyl ligands for a monometallic complex, all three of them bound η < sup > 5 </ sup >.

A structural trend for the series MCp < sub > 2 </ sub > involves the variation of the M-C bonds, which elongate as the valence electron count deviates from 18 .< ref > Kevin R. Flower, Peter B.

There is a natural homomorphism η: G → G < sup >^</ sup >, and the image of G under this homomorphism is dense in G < sup >^</ sup >.

The homomorphism η is characterized by the following universal property: given any profinite group H and any group homomorphism f: G → H, there exists a unique continuous group homomorphism g: G < sup >^</ sup > → H with f

A wheel power divided by the initial jet power, is the turbine efficiency, η = 4u ( V < sub > i </ sub > − u )/ V < sub > i </ sub >< sup > 2 </ sup >.

In Modern Greek usage ( and since the Roman Imperial period ), the letters < η > < ι > < υ > and the letter combinations < ει > < oι > < υι > may be pronounced.

The regular, line driven stellar winds can only stand for a mass loss rate of around 10 < sup >− 4 </ sup >– 10 < sup >− 3 </ sup > solar masses per year, whereas mass loss rates of up to 0. 5 solar masses per year are needed to understand the η Carinae outbursts.

Five bright stars of Scutum ( α Sct, β Sct, δ Sct, ε Sct and η Sct ) was a latter designation of 1, 6, 2, 3 and 9 Aquilae

η Canis Majoris is classified as an Alpha Cygni type variable star and its brightness varies from magnitude + 2. 38 to + 2. 48.

The Minkowski inner product is a map ( i. e. given any two vectors v, w in M we define η ( v, w ) as a real number ) which satisfies properties ( 1 ), ( 2 ), and ( 3 ) listed here, as well as property ( 4 ) given below:

These statements are meaningful once we explain the natural structures of algebra and coalgebra in all the vector spaces involved besides B: ( K, ∇< sub > 0 </ sub >, η < sub > 0 </ sub >) is a unital associative algebra in an obvious way and ( B ⊗ B, ∇< sub > 2 </ sub >, η < sub > 2 </ sub >) is a unital associative algebra with unit and multiplication

Then, diagrams 1 and 3 say that Δ: B → B ⊗ B is a homomorphism of unital ( associative ) algebras ( B, ∇, η ) and ( B ⊗ B, ∇< sub > 2 </ sub >, η < sub > 2 </ sub >)

diagrams 2 and 4 say that ε: B → K is a homomorphism of unital ( associative ) algebras ( B, ∇, η ) and ( K, ∇< sub > 0 </ sub >, η < sub > 0 </ sub >):

where ε < sub > r </ sub > is the dielectric constant of the dispersion medium, ε < sub > 0 </ sub > is the permittivity of free space ( C² N < sup >− 1 </ sup > m < sup >− 2 </ sup >), η is dynamic viscosity of the dispersion medium ( Pa s ), and ζ is zeta potential ( i. e., the electrokinetic potential of the slipping plane in the double layer ).

( 1 − 2 < sup > 1 − s </ sup >) ζ ( s ), " the pole of ζ ( s ) at s = 1 is cancelled by the zero of the other factor " ( Titchmarsh, 1986, p. 17 ), and as a result η ( 1 ) is neither infinite nor zero.

For non-isotropic ( anisotropic ) coatings, the optimal coating depends on the shape of the target and the radar direction, but duality, the symmetry of Maxwell's equations between the electric and magnetic fields, tells one that optimal coatings have η < sub > 0 </ sub > × η < sub > 1 </ sub > = 377 < sup > 2 </ sup > Ω < sup > 2 </ sup >, where η < sub > 0 </ sub > and η < sub > 1 </ sub > are perpendicular components of the anisotropic surface impedance, aligned with edges and / or the radar direction.

* For each object X in C, ( F ( X ), η < sub > X </ sub >) is an initial morphism from X to G. That is, for all f: X → G ( Y ) there exists a unique g: F ( X ) → Y for which the following diagrams commute.

If, for every object X in C, the morphism η < sub > X </ sub > is an isomorphism in D, then η is said to be a ( or sometimes natural equivalence or isomorphism of functors ).

The formulas and show that η < sub > G </ sub > is a group homomorphism which is its own inverse.

More strongly, if one wishes to prove that X and G ( X ) are not naturally isomorphic, without reference to a particular isomorphism, this requires showing that for any isomorphism η, there is some A with which it does not commute ; in some cases a single automorphism A works for all candidate isomorphisms η, while in other cases one must show how to construct a different A < sub > η </ sub > for each isomorphism.

diagrams 3 and 4 say that η: K → B is a homomorphism of ( counital coassociative ) coalgebras ( K, Δ < sub > 0 </ sub >, ε < sub > 0 </ sub >) and ( B, Δ, ε ):

* The modular discriminant Δ ( τ ) is proportional to the 24th power of the Dedekind eta function η ( τ ): Δ ( τ ) = ( 2π )< sup > 12 </ sup > η ( τ )< sup > 24 </ sup >.

A well-known example of this is from the first such molecule to be synthesized with a coordinated hydrogen ligand ( dihydrogen complex ): W ( CO )< sub > 3 </ sub >( PPri < sub > 3 </ sub >)< sub > 2 </ sub >( η < sup > 2 </ sup >- H < sub > 2 </ sub >).

Because the clocks had been on average well above sea level, this meant that TAI slowed down, by about 10 < sup >− 12 </ sup >.

Algeria has always been a source of inspiration for different painters who tried to immortalize the prodigious diversity of the sites it offers and the profusion of the facets that passes its population, which offers for Orientalists between the 19 < sup > th </ sup > century and the 20 < sup > th </ sup > century, a striking inspiration for a very rich artistic creation like Eugène Delacroix with his famous painting women of Algiers in their apartment or Etienne Dinet or other painters of world fame like Pablo Picasso with his painting women of Algiers, or painters issued from the Algiers school.

* If it is required to use a single number X as an estimate for the value of numbers, then the arithmetic mean does this best, in the sense of minimizing the sum of squares ( x < sub > i </ sub > − X )< sup > 2 </ sup > of the residuals.

When there are only two means to compare, the t-test and the ANOVA F-test are equivalent ; the relation between ANOVA and t is given by F = t < sup > 2 </ sup >.

The Arrhenius definition states that acids are substances which increase the concentration of hydronium ions ( H < sub > 3 </ sub > O < sup >+</ sup >) in solution.

The reason why pHs of acids are less than 7 is that the concentration of hydronium ions is greater than 10 < sup >− 7 </ sup > moles per liter.

An Arrhenius acid is a substance that increases the concentration of the hydronium ion, H < sub > 3 </ sub > O < sup >+</ sup >, when dissolved in water.

The International Time Bureau ( BIH ) began a time scale, T < sub > m </ sub > or AM, in July 1955, using both local caesium clocks and comparisons to distant clocks using the phase of VLF radio signals.

All 128 ASCII characters, including non-printable characters ( represented by their abbreviations ). The 95 ASCII graphic characters are numbered from 20 < sub > hexadecimal | hex </ sub > to 7E < sub > hexadecimal | hex </ sub > ( decimal 32 to 126 ).

The " space " character had to come before graphics to make sorting easier, so it became position 20 < sub > hex </ sub >; for the same reason, many special signs commonly used as separators were placed before digits.

To keep options available for lower case letters and other graphics, the special and numeric codes were arranged before the letters, and the letter " A " was placed in position 41 < sub > hex </ sub > to match the draft of the corresponding British standard.

The @ symbol was not used in continental Europe and the committee expected it would be replaced by an accented À in the French variation, so the @ was placed in position 40 < sub > hex </ sub > next to the letter A.
