The company's profitability rose enormously, from a pretax profit of £818,000 on a turnover of £4.6 million in 1980–81 to £8.55 million on a turnover of £27.17 million in 1981–82. Clive Sinclair became one of the UK's highest-profile businessmen and a millionaire, receiving a £1 million bonus on top of a salary of £13,000. [ 134 ]
A thallium atom has 81 electrons, arranged in the electron configuration [Xe]4f 14 5d 10 6s 2 6p 1; of these, the three outermost electrons in the sixth shell are valence electrons. Due to the inert pair effect , the 6s electron pair is relativistically stabilised and it is more difficult to get these involved in chemical bonding than it is for ...
Thallium (81 Tl) has 41 isotopes with atomic masses that range from 176 to 216. 203 Tl and 205 Tl are the only stable isotopes and 204 Tl is the most stable radioisotope with a half-life of 3.78 years.
The Nissan Z engine is a series of automobile and light truck four-cylinder engines that was engineered by Nissan Machinery, manufactured by the Nissan Motor Company from 1979 through August 1989. All Z engines had 4 cylinders, a total of 8 valves and a single overhead camshaft (SOHC) .
The MG 81 is a German belt fed 7.92×57mm Mauser machine gun which was used in flexible installations in World War II Luftwaffe aircraft, in which capacity it replaced the older drum magazine-fed MG 15. The MG 81 was developed by Mauser as a derivative of their successful MG 34 general-purpose machine gun. Development focus was to reduce ...
The character set in the ZX81 was derived from the ZX80 character set.They have mostly the same code points, e.g. for A-Z and 0-9, but the code points are different for the block graphics characters, the symbols ", -, +, *, /, =, >, <, and the BASIC keyword tokens (with many new added).

A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
