THE (5-PHENYL-2-OXAZOLYL)PYRIDINES AS FLUORESCENT pH INDICATORS. AN APPLICATION TO CHEMICAL RADIATION DOSIMETRY
The three isomeric (5-phenyl-2-oxazolyl)pyridines have been shown to be sensitive fluorescent pH indicators which show a pronounced change to increased visible fluorescence as the pH is lowered. Absorption and fluorescence spectral data and pK values are given. Selective excitation of fluorescence from the conjugate acid in the presence of the free base was found possible. The sensitivity of the 4-isomer was demonstrated to be adequate for determining the small amounts of acid produced in certain chemical dosimeter systems. (auth)

COMPRESSIBILITY FACTORS AND FUGACITY COEFFICIENTS CALCULATED FROM THE BEATTIE-BRIDGEMAN EQUATION OF STATE FOR HYDROGEN, NITROGEN, OXYGEN, CARBON DIOXIDE, AMMONIA, METHANE, AND HELIUM
Compressibility factors and fugacity coefficients for hydrogen, niftrogen, oxygen, carbon dioxide, ammonia, methane, and helium were calculated by use of the Beattie-Bridgeman equation of state. The results are tabulated for various pressures up to several hundred atmospheres, and temperatures up to several hundred degrees, at sufficiently close intervals to allow for easy interpolation. A comparison is made of the calculated compressibility factors with the experimental values over those ranges of temperatures and pressure where the latter are available. From this comparison an attempt is made to indicate the probable reliability of the fugacity coefficients by the number of significant figures shown. (auth)

Critical Experiments With 2.09% U$Sup 235$-Enriched Uranium Metal Plates in Water
Experiments were performed with 2.09% U/sup 235/-enriched uranium metal plates in a light-water-moderated and -reflected assembly. Each plate was 30 in. long, 31/8 in. wide, and 1/4 in. thick and contained 7.09 kg of uranium. In the first assemblies the plates were arranged in rows with edges adjacent, and the spacing between rows was varied from 5/8 to 1 1/8in. The optimum spacing was about 7/8 in. With the spacing between rows maintained at 7/8 in., the spacing between the edges of the plates was varied from 0 to 5/8 in. The optimum spacing between edges was 5/16 in. The minimum critical mass in these assemblies was 6.74 kg of U/sup 235/. (auth)
