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 most stable of these is < sup > 154 </ sup > Dy with a half-life of approximately 3 years, followed by < sup > 159 </ sup > Dy with a half-life of 144. 4 days.

Besides the natural radioisotope < sup > 151 </ sup > Eu, 35 artificial radioisotopes have been characterized, the most stable being < sup > 150 </ sup > Eu with a half-life of 36. 9 years, < sup > 152 </ sup > Eu with a half-life of 13. 516 years, and < sup > 154 </ sup > Eu with a half-life of 8. 593 years.

19 neptunium radioisotopes have been characterized, with the most stable being < sup > 237 </ sup > Np with a half-life of 2. 14 million years, < sup > 236 </ sup > Np with a half-life of 154, 000 years, and < sup > 235 </ sup > Np with a half-life of 396. 1 days.

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 ).

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

Naturally occurring dysprosium is composed of 7 isotopes, the most abundant of which is < sup > 164 </ sup > Dy.

Actinium is found only in traces in uranium ores as the isotope < sup > 227 </ sup > Ac, which decays with a half-life of 21. 772 years, predominantly emitting beta particles.

It decays by emission of a α-particle to < sup > 237 </ sup > Np ; the half-life of this decay was first determined as 510 ± 20 years but then corrected to 432. 2 years.

The part of the function that depends on the distance from the nucleus has nodes ( radial nodes ) and decays as e < sup >(- distance )</ sup > from the nucleus.

Five atoms of < sup > 262 </ sup > Bh were detected using the method of correlation of genetic parent-daughter decays.

In 2005 they measured 33 decays of < sup > 262 </ sup > Bh and 2 atoms of < sup > 261 </ sup > Bh, providing a 1n excitation function and some spectroscopic data of both < sup > 262 </ sup > Bh isomers.

< sup > 41 </ sup > Ca has received much attention in stellar studies because it decays to < sup > 41 </ sup > K, a critical indicator of solar-system anomalies.

These are all considered stable, although < sup > 156 </ sup > Dy decays by alpha decay with a half-life of over 1 × 10 < sup > 18 </ sup > years.
