The Viking model was born out of discussions at Downer for a bigger version of the "Model 260" with at least 300 horsepower. The company was based in Minnesota and employed skilled craftsmen who manufactured the wing from spruce, and the new 300 hp model was named the "Viking" in respect to the many Scandinavians of the area.
AviaBellanca Aircraft Corporation was an American aircraft design and manufacturing company. Prior to 1983, it was known as the Bellanca Aircraft Company. [1] The company was founded in 1927 by Giuseppe Mario Bellanca, although it was preceded by previous businesses and partnerships in which aircraft with the Bellanca name were produced, including Wright-Bellanca, in which he was in ...

The free androgen index is intended to give a guide to the free testosterone level, but it is not very accurate (especially in males — see endocrine society commentary below). Consequently, there are no universally agreed 'normal ranges', and levels slightly above or below quoted laboratory reference ranges may not be clinically significant.

Testosterone is the primary male sex hormone and androgen in males. [3] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
A higher performance design revision was granted FAA approval as the 14-19 Cruisemaster on September 26, 1949. [3] The new model featured structural upgrades, a 190 hp (142 kW) Lycoming O435-A engine, an increased gross weight of 2,600 lbs, hydraulically operated landing gear and flaps, and a deluxe interior. 99 of these airplanes were produced between 1949 and 1951.
The free androgen index, essentially a calculation based on total testosterone and sex hormone-binding globulin levels, is the worst predictor of free testosterone levels and should not be used. [17] Measurement by equilibrium dialysis or mass spectroscopy is generally required for accurate results, particularly for free testosterone which is ...
