The parameterized post-Newtonian formalism or PPN formalism, is a version of this formulation that explicitly details the parameters in which a general theory of gravity can differ from Newtonian gravity.
Bis(triphenylphosphine)iminium chloride is the chemical compound with the formula [((C 6 H 5) 3 P) 2 N]Cl, often abbreviated [(Ph 3 P) 2 N]Cl, where Ph is phenyl C 6 H 5, or even abbreviated [PPN]Cl or [PNP]Cl or PPNCl or PNPCl, where PPN or PNP stands for (Ph 3 P) 2 N.
Formulation terminology follows a 2-letter convention: (e.g. GR: granules) listed by CropLife International (formerly GIFAP then GCPF) in the Catalogue of Pesticide Formulation Types (Monograph 2); see: download page. Some manufacturers do not follow these industry standards, which can cause confusion for users.
Prescription lipid parenteral nutrition formulation. Solutions for total parenteral nutrition may be customized to individual patient requirements, or standardized solutions may be used. The use of standardized parenteral nutrition solutions is cost-effective and may provide better control of serum electrolytes. [40]
Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water.The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution.
