Spin polarization of 129 Xe can persist from several seconds for xenon atoms dissolved in blood [86] to several hours in the gas phase [87] and several days in deeply frozen solid xenon. [88] In contrast, 131 Xe has a nuclear spin value of 3 ⁄ 2 and a nonzero quadrupole moment, and has t 1 relaxation times in the millisecond and second ranges ...
The XE is a development of the Mosquito Air, with a cockpit fairing and a more sophisticated exhaust system, plus a rotor diameter increased by 40 cm (15.7 in) to support the higher gross weight. The aircraft was designed to comply with the US Experimental – Amateur-built and European microlight aircraft rules.

A Beechcraft Model 95 in flight. Designed as a competitor to the Cessna 310 and the Piper Apache, the Travel Air (developed as the Badger) [3] took many design features from previous Beechcraft airplanes. [4] It took its basic design from the Model 35 Bonanza, [5] fitted with the vertical stabilizer from the T-34 Mentor, and two four-cylinder ...

Naturally occurring xenon (54 Xe) consists of seven stable isotopes and two very long-lived isotopes. Double electron capture has been observed in 124 Xe (half-life 1.8 ± 0.5(stat) ± 0.1(sys) × 10 22 years) [2] and double beta decay in 136 Xe (half-life 2.165 ± 0.016(stat) ± 0.059(sys) × 10 21 years), [7] which are among the longest measured half-lives of all nuclides.
Steve Jobs introduced the MacBook Air during Apple’s keynote address at the 2008 Macworld conference on January 15, 2008. [4] The first MacBook Air was a 13.3-inch model, initially promoted as the world's thinnest notebook at 1.9 cm (0.75 in) (a previous record holder, 2005's Toshiba Portege R200, was 1.98 cm (0.78 in) high).
