590 Madison Avenue, also known as the IBM Building, is a skyscraper at 57th Street and Madison Avenue in the Midtown Manhattan neighborhood of New York City.Designed by Edward Larrabee Barnes and Associates the 41-story, 603-foot (184 m)-tall tower was developed for the technology company IBM and built from 1978 to 1983.
Carbon-14 can also be produced by other neutron reactions, including in particular 13 C(n,γ) 14 C and 17 O(n,α) 14 C with thermal neutrons, and 15 N(n,d) 14 C and 16 O(n, 3 He) 14 C with fast neutrons. [28] The most notable routes for 14 C production by thermal neutron irradiation of targets (e.g., in a nuclear reactor) are summarized in the ...

Soon after the publication of Libby's 1949 paper in Science, universities around the world began establishing radiocarbon-dating laboratories, and by the end of the 1950s there were more than 20 active 14 C research laboratories. It quickly became apparent that the principles of radiocarbon dating were valid, despite certain discrepancies, the ...
The laboratory is guarded by a Department of Energy Protective Force, has a full service fire department, and has its own ZIP code (11973). In total, the lab spans a 5,265-acre (21 km 2) area that is mostly coterminous with the hamlet of Upton, New York. BNL is served by a rail spur operated as-needed by the New York and Atlantic Railway.
The next step, to correct for fractionation, can be done using either the 14 C / 12 C ratio or the 14 C / 13 C ratio, and also depends on which of the two possible standards was measured: HOxI or HoxII. R' std is then R' HOxI or R' HOxII, depending on which standard was used. The four possible equations are as follows. First, if the 14 C / 12

The Southwark Emery universal testing machine has a capacity of 600,000 lb (3 MN) and can test specimens up to 18 ft (5.5 m) tall. Carleton Lab, an endowed research center overseen by the Trustees of the Robert A. W. Carleton Laboratory, is one of the largest labs on Columbia’s Morningside Heights campus.
