The 4.6×30mm (designated as the 4,6 × 30 by the C.I.P. [6]) cartridge is a small- caliber, high- velocity, smokeless powder, rebated, bottleneck, centerfire cartridge designed for personal defense weapons (PDW) developed by German armament manufacturer Heckler & Koch (HK) in 1999. It was designed primarily for the MP7 PDW to minimize weight ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and ...
For full-frame 35 mm format (24 mm × 36 mm, 43 mm diagonal), a widely used CoC limit is d /1500, or 0.029 mm for full-frame 35 mm format, which corresponds to resolving 5 lines per millimeter on a print of 30 cm diagonal. Values of 0.030 mm and 0.033 mm are also common for full-frame 35 mm format.
2.58 × 10−4 A ⋅ s / kg. The roentgen or röntgen ( / ˈrɛntɡən, - dʒən, ˈrʌnt -/; [2] symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air ( statcoulomb per kilogram).
An image intensifier or image intensifier tube is a vacuum tube device for increasing the intensity of available light in an optical system to allow use under low-light conditions, such as at night, to facilitate visual imaging of low-light processes, such as fluorescence of materials in X-rays or gamma rays (X-ray image intensifier), or for conversion of non-visible light sources, such as ...
Dry weight. 483 lb (219 kg) (4.0 L engine) The AMC straight-6 engine is a family of straight-six engines that were produced by American Motors Corporation (AMC), and used in AMC passenger cars and Jeep vehicles from 1964 through 2006. Production continued after Chrysler acquired AMC in 1987. AMC's first inline-six engine was a legacy model ...
The world's population receives an average of 0.4 millisieverts (mSv) of cosmic radiation annually (separate from other sources of radiation exposure like inhaled radon) due to atmospheric shielding. At 12 km altitude, above most of the atmosphere's protection, radiation as an annual rate rises to 20 mSv at the equator to 50–120 mSv at the ...
Jackovich will be in the water this summer for Australia and could face off against an American team with 6-8 co-founder Maggie Steffens. Holmes, the fencer, said her best time management tools ...
