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.

η < sup > 2 </ sup > ( eta-squared ):

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.

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.

The simplest possible alkane ( the parent molecule ) is methane, CH < sub > 4 </ sub >.

Hydrogen chloride ( HCl ) and ammonia combine under several different conditions to form ammonium chloride, NH < sub > 4 </ sub > Cl.

Only a limited number of actinium compounds are known including AcF < sub > 3 </ sub >, AcCl < sub > 3 </ sub >, AcBr < sub > 3 </ sub >, AcOF, AcOCl, AcOBr, Ac < sub > 2 </ sub > S < sub > 3 </ sub >, Ac < sub > 2 </ sub > O < sub > 3 </ sub > and AcPO < sub > 4 </ sub >.

Except for AcPO < sub > 4 </ sub >, they are all similar to the corresponding lanthanum compounds and contain actinium in the oxidation state + 3.

Next consider the sample ( 10 < sup > 8 </ sup > + 4, 10 < sup > 8 </ sup > + 7, 10 < sup > 8 </ sup > + 13, 10 < sup > 8 </ sup > + 16 ), which gives rise to the same estimated variance as the first sample.

If F ≥ F < sub > Critical </ sub > ( Numerator DF, Denominator DF, α )

With the formula C < sub > n </ sub > H < sub > 2n + 2 </ sub >, Alkanes belong to a homologous series of organic compounds in which the members differ by a constant relative molecular mass of 14.

The number of carbon atoms is used to define the size of the alkane ( e. g., C < sub > 2 </ sub >- alkane ).

However, this was significantly less successful than conventional regulation in the European Union, which saw a decrease of over 70 % in SO < sub > 2 </ sub > emissions during the same time period.

However, Beethoven did not retain this version, and kept rewriting until he had found its final form, with the words < em lang =" de ">" O Freunde, nicht diese Töne "</ em > (" O friends, not these tones ").

However, later evidence gave a much lower SF branching for < sup > 261 </ sup > Bh reducing confidence in this assignment.

However, it is expensive to grow and wastes space proportional to 2 < sup > h </ sup >-n for a tree of depth h with n nodes.

However, there will be several terms of the form x < sup > n − 2 </ sup > y < sup > 2 </ sup >, one for each way of choosing exactly two binomials to contribute a y.

However, as 1 + ( k + 1 ) x + kx < sup > 2 </ sup > ≥ 1 + ( k + 1 ) x ( since kx < sup > 2 </ sup > ≥ 0 ), it follows that ( 1 + x )< sup > k + 1 </ sup > ≥ 1 + ( k + 1 ) x, which means the statement is true for r = k + 1 as required.

< cite id = disputedinjunction > The Vatican archives contain an unsigned copy of a more strongly worded formal injunction purporting to have been served on Galileo shortly after Bellarmine's admonition, ordering him " not to hold, teach, or defend " the condemned doctrine " in any way whatever, either orally or in writing ", and threatening him with imprisonment if he refused to obey .</ cite > However, whether this injunction was ever properly served on Galileo is a subject of much scholarly disagreement.

However, the law of mass action is valid only for concerted one-step reactions that proceed through a single transition state and is not valid in general because rate equations do not, in general, follow the stoichiometry of the reaction as Guldberg and Waage had proposed ( see, for example, nucleophilic aliphatic substitution by S < sub > N </ sub > 1 or reaction of hydrogen and bromine to form hydrogen bromide ).

IUPAC prefers that isotope symbols be written in superscript notation when practical, for example < sup > 12 </ sup > C and < sup > 235 </ sup > U. However, other notations, such as carbon-12 and uranium-235, or C-12 and U-235, are also used.

However, some biological substances commonly called " monosaccharides " do not conform to this formula ( e. g., uronic acids and deoxy-sugars such as fucose ), and there are many chemicals that do conform to this formula but are not considered to be monosaccharides ( e. g., formaldehyde CH < sub > 2 </ sub > O and inositol ( CH < sub > 2 </ sub > O )< sub > 6 </ sub >).

However, ocean acidification by invading anthropogenic CO < sub > 2 </ sub > may affect the biological pump by negatively impacting calcifying organisms such as coccolithophores, foraminiferans and pteropods.

However, current research shows that several trapping mechanisms immobilize the CO < sub > 2 </ sub > underground, reducing the risk of leakage.

However, the converse may fail in non-Euclidean R < sup > n </ sup >.

However, it has higher resistivity and dielectric strength than most insulators commonly available in microfabrication ( 10 < sup > 16 </ sup > Ω · cm and 10 MV / cm, respectively ).

However, SO < sub > 2 </ sub > emissions are usually significantly higher.

However, more commonly the unit mol / L (= mol / dm < sup > 3 </ sup >) is used.

However Newton's laws of motion apply only in the stationary frame and describe dynamics in terms of the absolute acceleration d < sup > 2 </ sup > r / dt < sup > 2 </ sup >.

However, more recent experiments have demonstrated that cells whose centrioles have been removed via laser ablation can still progress through the G < sub > 1 </ sub > stage of interphase before centrioles can be synthesized later in a de novo fashion.

" Columbia University </ ref > However, the incineration and burning of forest plants to clear land releases large amounts of CO < sub > 2 </ sub >, which contributes to global warming.

However, for optimal ligation efficiency with cohesive-ended fragments (" sticky ends "), the optimal enzyme temperature needs to be balanced with the melting temperature T < sub > m </ sub > ( also the annealing temperature ) of the sticky ends being ligated.
