Now consider some examples of the influence of sedimentation process upon PT sensitivity. Let us consider the application of fine-dispersed magnesia oxide powder as the developer. Using the methods described in [4] we experimentally determined the next characteristics of the developer s layer IT s 0,5, Re s 0,25 pm. We used dye sensitive penetrant Pion , which has been worked out in the Institute of Applied Physics of National Academy of Sciences of Belarus. Its surface tension ct = 2,5 10 N m V It can be shown that minimum width of an indication of magnesia powder zone, imbibed by Pion , which can be registered, is about W s 50 pm. Assume that n = 1.

Besides support by governmental agencies there is also support of research by industry, varied foundations and charitable organizations, and individual donors. This all adds to the diversity of our research enterprise and its vitality. The U.S. National Academy of Sciences itself does not support research to any significant degree. As a private or-...

Standards for food-grade chemicals in the United States are set by the Committee on Eood Chemicals Codex of the National Academy of Sciences (NAS) which pubHshes them in the Food Chemicals Codex (ECC) (6) (see also Eood additives). Standards for laboratory reagents are set by the American Chemical Society (ACS) Committee on Analytical Reagents and are pubHshed in Feagent Chemicals—A.CS Specifications (7). Standards for electronic-grade chemicals, which have extremely low limits for trace ions, are pubHshed aimually in The Book of SEMI Standards (BOSS) by Semiconductor Equipment and Materials International (SEMI) (8). 

Action to compile standards for food-grade chemicals did not take place until after the enactment of the Food Additives Amendment to the Food, Dmg, and Cosmetic Act in 1958 (13). This amendment stated that substances added to foods should be of food-grade quaUty, but it contained no criteria by which such quahty could be determined (see also Colorants forfood, drugs, cosmetics, and medicaldevices). The Food Protection Committee of the National Academy of Sciences—National Research Council (NAS—NRC) therefore undertook the project of producing a Food Chemicals Codex. 

The Food Chemicals Codex. The Food Chemicals Codex is developed by the Committee on Pood Chemicals Codex, which is a part of the Pood and Nutrition Board, Institute of Medicine, National Academy of Sciences, under a contract with the U.S. PDA. The Committee has the responsibihty for the development and revision of the PCC. To meet this responsibiUty, the Committee also contacts manufacturers, trade associations, and other knowledgeable parties to obtain comments and criticisms of monographs proposed by the committee. Broader pubHc input is sought by pubhcation, by the PDA in the FederalFegister, of current committee activity regarding new and revised monographs proposed for inclusion in the PCC.
