2. Dietary Reference Intake - Wikipedia

   en.wikipedia.org/wiki/Dietary_Reference_Intake

   The Dietary Reference Intake (DRI) is a system of nutrition recommendations from the National Academy of Medicine (NAM) [a] of the National Academies (United States). [1] It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances (RDA s, see below). The DRI values differ from those used in ...

3. Ionization energies of the elements (data page) - Wikipedia

   en.wikipedia.org/wiki/Ionization_energies_of_the...

   Values from CRC are ionization energies given in the unit eV; other values are molar ionization energies given in the unit kJ/mol. The first of these quantities is used in atomic physics, the second in chemistry, but both refer to the same basic property of the element. To convert from "value of ionization energy" to the corresponding "value of ...

   The National Association for PET Container Resources (NAPCOR) defines PET as: "Polyethylene terephthalate items referenced are derived from terephthalic acid (or dimethyl terephthalate) and mono ethylene glycol, wherein the sum of terephthalic acid (or dimethyl terephthalate) and mono ethylene glycol reacted constitutes at least 90 percent of ...

8. Thermodynamic databases for pure substances - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_databases...

   Thermodynamic data. Thermodynamic data is usually presented as a table or chart of function values for one mole of a substance (or in the case of the steam tables, one kg). A thermodynamic datafile is a set of equation parameters from which the numerical data values can be calculated. Tables and datafiles are usually presented at a standard ...
