A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
NIST had an operating budget for fiscal year 2007 (October 1, 2006 – September 30, 2007) of about $843.3 million. NIST's 2009 budget was $992 million, and it also received $610 million as part of the American Recovery and Reinvestment Act. [18] NIST employs about 2,900 scientists, engineers, technicians, and support and administrative personnel.
The National Map is a significant contribution to the U.S. National Spatial Data Infrastructure (NSDI) from the Federal Geographic Data Committee (FGDC) and currently is being transformed to better serve the geospatial community by providing high quality, integrated geospatial data and improved products and services including new generation ...
In the same year it appeared at Cambridge University Press under the title NIST Handbook of Mathematical Functions. [3] In contrast to A&S, whose initial print run was done by the U.S. Government Printing Office and was in the public domain, NIST asserts that it holds copyright to the DLMF under Title 17 USC 105 of the U.S. Code.

The International Chemical Identifier (InChI, pronounced / ˈ ɪ n tʃ iː / IN-chee) [3] is a textual identifier for chemical substances, designed to provide a standard way to encode molecular information and to facilitate the search for such information in databases and on the web.
NIST replaced these codes with the more permanent GNIS Feature ID, maintained by the U.S. Board on Geographic Names. The GNIS database is the official geographic names repository database for the United States, and is designated the only source of geographic names and locative attributes for use by the agencies of the Federal Government.

Thermodynamic databases contain information about thermodynamic properties for substances, the most important being enthalpy, entropy, and Gibbs free energy.Numerical values of these thermodynamic properties are collected as tables or are calculated from thermodynamic datafiles.
