X-ray bursters are one class of X-ray binary stars exhibiting X-ray bursts, periodic and rapid increases in luminosity (typically a factor of 10 or greater) that peak in the X-ray region of the electromagnetic spectrum. These astrophysical systems are composed of an accreting neutron star and a main sequence companion 'donor' star. There are ...
a. Different explosives of compatibility group A should be packaged separately. b. Explosives of compatibility group L shall only be packed with an identical explosive. c. Explosive articles of the compatibility group C, D, or E may be packed together, and the whole packaged shall be treated as belonging to compatibility group E. d.
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
X-ray star may refer to: Be/X-ray binary, a class of high-mass X-ray binaries that consist of a Be star and a neutron star; X-ray binary, a class of binary stars that are luminous in X-rays; X-ray burster, a class of X-ray binary stars exhibiting periodic and rapid increases in luminosity that peak in the X-ray regime of the electromagnetic ...
The device was originally built in the 1970s for high-power x-ray research, was later re-directed to studies for the Strategic Defense Initiative (SDI), and is now being used for magnetized target fusion research. Shiva Star was named after the Hindu god Shiva, partly because its prototype originally had four "arms"; it later got six "arms".
The eXaminer 3DX 6000 explosive detection system developed by L-3 operates similarly to the CTX system. In 2013 Rapiscan Systems made the first delivery of its RTT product. [2] This machine operates with a non-rotating 360 degree multi source X-ray tube and detector array CT imaging system so the only moving part is the conveyor belt.
And while Starship can hold up to 3 million (1,500 metric tons) of propellant, the spacecraft itself is only capable of hauling up to 55,000 pounds (250 metric tons) of extra cargo to orbit ...
The device combined two slightly different frequencies which when heard would be heard as the sum of the two frequencies (ultrasonic) and the difference between the two frequencies (infrasonic) e.g. two directional speakers emitting 16,000 Hz and 16,002 Hz frequencies would produce in the ear two frequencies of 32,002 Hz and 2 Hz.
