With a production order of 10.5 million, it became the largest single press run of any record at the time. [citation needed] 7 inch (17 cm) Between 1892 and 1900, the Berliner Gramophone Company released 7" records, to be played with a recently upgraded Gram-O-Phone reproducing machine.
Clear evidence of the presence of 26 Al at an abundance ratio of 5×10 −5 was shown by Lee et al. [18] [19] The value (26 Al/ 27 Al ~ 5 × 10 −5) has now been generally established as the high value in early Solar System samples and has been generally used as a refined time scale chronometer for the early Solar System. Lower values imply a ...
2007 Toyota Yaris hatchback owner's manual 1919 Ford Motor Company car and truck operating manual. An owner's manual (also called an instruction manual or a user guide) is an instructional book or booklet that is supplied with almost all technologically advanced consumer products such as vehicles, home appliances and computer peripherals.
The greater the number of protons, the more neutrons are required to stabilize a nuclide; nuclides with larger values for Z require an even larger number of neutrons, N > Z, to be stable. The valley of stability is formed by the negative of binding energy, the binding energy being the energy required to break apart the nuclide into its proton ...
Before the advent of the compact disc, flexi discs were sometimes used as a means to include sound with printed material such as magazines and music instruction books. [3] A flexi disc could be moulded with speech or music and bound into the text with a perforated seam, at very little cost and without any requirement for a hard binding. [4]

Allied Communications Publications are documents developed by the Combined Communications-Electronics Board and NATO, which define the procedures for communicating in computer messaging, radiotelephony, radiotelegraph, radioteletype (RATT), air-to-ground signalling (panel signalling), and other forms of communications used by the armed forces of the five CCEB member countries and/or NATO.
Isotope half-lives. The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. Isotopes are nuclides with the same number of protons but differing numbers of neutrons; that is, they have the same atomic number and are therefore the same chemical element. Isotopes neighbor ...
