Origin is a proprietary computer program for interactive scientific graphing and data analysis.It is produced by OriginLab Corporation, and runs on Microsoft Windows.It has inspired several platform-independent open-source clones and alternatives like LabPlot and SciDAVis.
Naturally occurring chromium (24 Cr) is composed of four stable isotopes; 50 Cr, 52 Cr, 53 Cr, and 54 Cr with 52 Cr being the most abundant (83.789% natural abundance). 50 Cr is suspected of decaying by β + β + to 50 Ti with a half-life of (more than) 1.8×10 17 years.
It is poor engineering to specify a CR instead of an R simply on the theory of enforcing good workmanship. CR is for critical features whose performance truly requires near-perfect geometry. Like most such characteristics, its presence increases the price of the part, because it raises the costs of manufacturing and quality assurance. CRES
People didn't just fill their plates this Thanksgiving weekend -- data shows they also filled their online shopping carts. Black Friday online shopping this year set a new high, reaching $10.8 ...
A 38-year-old man has been jailed in France for raping his teenage daughter for years and inviting other men, many of them much older, to join in the abuse.
Thus we can find a graph with at least e − cr(G) edges and n vertices with no crossings, and is thus a planar graph. But from Euler's formula we must then have e − cr(G) ≤ 3n, and the claim follows. (In fact we have e − cr(G) ≤ 3n − 6 for n ≥ 3). To obtain the actual crossing number inequality, we now use a probabilistic argument.
NFL players have sky-high salaries and contracts that would make the average person feel faint. They also get slapped with fines left and right, some frivolous and some substantial.
Naturally occurring chromium is composed of four stable isotopes; 50 Cr, 52 Cr, 53 Cr and 54 Cr, with 52 Cr being the most abundant (83.789% natural abundance). 50 Cr is observationally stable , as it is theoretically capable of decaying to 50 Ti via double electron capture with a half-life of no less than 1.3 × 10 18 years.
