and enzymes which terminate the action of peptides such as bradykinin and perhaps Substance Z were studied.

If the Z gyro is drifting, a current generated by the autocollimator is delivered to the gyro torquer to cancel the drift.

When the platform is level, **ye is a rotation about the Z axis of the platform Af.

Algeria had also won an Oscar for the movie Z, a political thriller directed by Costa Gavras.

It is conventionally represented by the symbol Z.

The atomic number, Z, should not be confused with the mass number, A, which is the number of nucleons, the total number of protons and neutrons in the nucleus of an atom.

The number of neutrons, N, is known as the neutron number of the atom ; thus, A = Z + N. Since protons and neutrons have approximately the same mass ( and the mass of the electrons is negligible for many purposes ), and the mass defect is usually very small compared to the mass, the atomic mass of an atom is roughly equal to A.

Atoms having the same atomic number Z but different neutron number N, and hence different atomic mass, are known as isotopes.

The conventional symbol Z comes from the German word meaning number / numeral / figure, which prior to the modern synthesis of ideas from chemistry and physics, merely denoted an element's numerical place in the periodic table.

Only after 1915, with the suggestion and evidence that this Z number was also the nuclear charge and a physical characteristic of atoms, did the word and its English equivalent atomic number come into common use.

This placement is consistent with the modern practice of ordering the elements by proton number, Z, but this number was not known or suspected at the time.

Moseley, after discussions with Bohr who was at the same lab ( and who had used Van den Broek's hypothesis in his Bohr model of the atom ), decided to test Van den Broek and Bohr's hypothesis directly, by seeing if spectral lines emitted from excited atoms fit the Bohr theory's demand that the frequency of the spectral lines be proportional to a measure of the square of Z.

To do this, Moseley measured the wavelengths of the innermost photon transitions ( K and L lines ) produced by the elements from aluminum ( Z = 13 ) to gold ( Z = 79 ) used as a series of movable anodic targets inside an x-ray tube.

This led to the conclusion ( Moseley's law ) that the atomic number does closely correspond ( with an offset of one unit for K-lines, in Moseley's work ) to the calculated electric charge of the nucleus, i. e. the proton number Z.

* In elementary arithmetic, the set of integers, Z, considered as a group under addition, has a unique nontrivial automorphism: negation.

Puttenham, in the time of Elizabeth I of England, wished to start from Elissabet Anglorum Regina ( Elizabeth Queen of the English ), to obtain Multa regnabis ense gloria ( By thy sword shalt thou reign in great renown ); he explains carefully that H is " a note of aspiration only and no letter ", and that Z in Greek or Hebrew is a mere SS.

William Drummond of Hawthornden, in an essay On the Character of a Perfect Anagram, tried to lay down permissible rules ( such as S standing for Z ), and possible letter omissions.

Kokh tombs in the Nazareth area have been excavated by B. Bagatti, N. Feig, Z. Yavor, and noted by Z. Gal.

Although Richard Feynman noted that a simplistic interpretation of the relativistic Dirac equation runs into problems with electron orbitals at Z > 1 / α = 137, suggesting that neutral atoms cannot exist beyond untriseptium, and that a periodic table of elements based on electron orbitals therefore breaks down at this point, a more rigorous analysis calculates the limit to be Z ≈ 173, but also that this limit would not actually spell the end of the periodic table.

Feeney noted, Z Channel's broadcast of Heaven's Gate first popularized the concept of a " director's cut.

To clarify the adjacent drawing, it should be noted that α rotates around the z-axis, β rotates around the N-axis ( i. e. X ’), and γ rotates around the Z-axis ( i. e. Z ’’), hence the name Z-X '- Z ’’.

PE ' Z is also noted for performing with Cyndi Lauper in a TV program.

Untriseptium, element 137, is sometimes called feynmanium ( symbol Fy ) because Richard Feynman noted that a simplistic interpretation of the relativistic Dirac equation runs into problems with electron orbitals at Z > 1 / α = 137, suggesting that neutral atoms cannot exist beyond untriseptium, and that a periodic table of elements based on electron orbitals therefore breaks down at this point.
