The 14.5×114mm (.57 calibre) is a heavy machine gun and anti-materiel rifle cartridge used by the Soviet Union, the former Warsaw Pact, modern Russia, and other countries.. It was originally developed for the PTRS and PTRD anti-tank rifles, and was later used as the basis for the KPV heavy machine gun that formed the basis of the ZPU series anti-aircraft guns that is also the main armament of ...

Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
Defined as 1 ⁄ 100 of the amount of energy required to warm one gram of air-free water from 0 to 100 °C at standard atmospheric pressure. [b] International Steam Table calorie (1929) ≈ 4.1868 J ≈ 0.003 9683 BTU ≈ 1.1630 × 10 −6 kW⋅h ≈ 2.6132 × 10 19 eV Defined as 1 ⁄ 860 "international" watt hours = 180 ⁄ 43 "international ...
A high school student explains her engineering project to a judge in Sacramento, California, in 2015.. Science, technology, engineering, and mathematics (STEM) is an umbrella term used to group together the distinct but related technical disciplines of science, technology, engineering, and mathematics.
[174] As a result, the milled AK-47s are capable of shooting 3–5 inch groups at 100 yards, whereas the stamped AKMs are capable of shooting 4–6 inch groups at 100 yards. [ 130 ] [ 174 ] The best shooters can hit a man-sized target at 800 meters within five shots (firing from a prone or supported position) or ten shots (standing).
Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
The solutions for R(t) depend on k and Λ, but some qualitative features of such solutions are general. First and most importantly, the length scale R of the universe can remain constant only if the universe is perfectly isotropic with positive curvature ( k = 1) and has one precise value of density everywhere, as first noted by Albert Einstein .
