The United States Air Force's 817th Expeditionary Air Support Operations Squadron (817 EASOS) is a combat support unit located at an undisclosed location in the Middle East. The 817 EASOS provides Tactical Command and Control of air power assets to the Joint Forces Air Component Commander and Joint Forces Land Component Commander for combat ...
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β.
The FT-817 is based on a similar circuit architecture as Yaesu's FT-857 and FT-897, so it is a compromise transceiver and incorporates its features to its low price ($670.- at its 2001 release). [3] The upgraded FT-817(N)D was launched in 2004. The difference between the two models is the addition of 60 meter band coverage in 5 fixed channels ...
TWI: Many of Atmels microcontrollers contain built-in support for interfacing to a two-wire bus, called Two-Wire Interface. This is essentially the same thing as the I²C interface by Philips, but that term is avoided in Atmel's documentation due to trademark issues. USI: Universal Serial Interface (not to be confused with USB). The USI is a ...
Humans love it when cats knead because the cute motion makes it look like cats are hard at work on a bakery assembly line. We know why cats knead. But here's why humans love it so much.
The long atmospheric lifetime of COS makes it the major source of stratospheric sulfate, though sulfur dioxide from volcanic activity can be significant too. [5] Carbonyl sulfide is also removed from the atmosphere by terrestrial vegetation by enzymes associated with the uptake of carbon dioxide during photosynthesis, and by hydrolysis in ocean ...
Drugs, weapons and human trafficking. That's probably what comes to mind when thinking about the black market -- but the illegal trade is more varied than you may think, and it also encompasses ...
The initial ATR 42-300 model remained in production until 1996, while the first upgraded (and broadly similar) model, designated as the ATR 42-320, was also produced until 1996. The -320 variant principally differed in that it was powered by a pair of the more-powerful PW121 engines, giving it improved performance over the 300.
