Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, John L. Hill, regarding a legal question submitted for clarification; Whether breakfast meetings of the Commissioners' Court are requried to be open to the public and preceded by notice under the Open Meetings Act.

A personnel monitoring program must include a well integrated combination of dose determination methods, and should not depend on a single dosimetry system. Many of the necessary techniques have become well developed and dependable, such as the personnel gamma dosimeters in use today. However, other monitoring methods are still not adequate. The two most important personnel monitoring problems remaining are development of personnel neutron dosimeter and in-vivo measurement of plutonium at sublung burden levels. Although there are a few techniques under development to attack these problems, satisfactory long-term solutions will require much more work. As the developments in nuclear power and medicine continue, the need for solutions to these problems will intensify. (auth)

The rate of assimilated nitrogen transfer from phytoplankton to zooplankton was measured under field conditions for natural mixed zooplankton populations using a nitrogen-15 tracer technique. The variability in rates, which ranged from 0.261 to 1.792 gram-atoms of phytoplankton nitrogen/gram-atoms of zooplankton nitrogen/24 hours, are thought to reflect a variability in the age frequency distribution of the zooplankton population. The data were used to calculate assimilation efficiencies which were found to range from 25.4 to 66.1 percent. The efficiency of 66.1 percent was taken to be the most accurate measurement for reasons discussed in the text.

Equilibrium water vapor pressure and total moisture content were measured for samples of TATB-10 percent Kel-F, TATB-6 percent Estane, and TATB-9 percent Viton in a temperature range from 296 to 365/sup 0/K. Heats of vaporization were obtained for temperatures from 296 to 333/sup 0/K. Below 333/sup 0/K the water in the samples behaved as dissolved water and the Clausius-Clapeyron equation was applicable, while above 333/sup 0/K the water dissolved in the samples became very mobile and for practical purposes it was considered to be available in its entirety in the gas phase. The total moisture content of the samples was found to be <0.0021, 0.0102, and 0.0165 wt. percent for TATB-Kel-F, TATB-Estane, and TATB-Viton, respectively. The data indicate that the transport of water in the samples was controlled by the permeation characteristics of the binders. Fair agreement was found between published relative permeation constants for the three binders and those derived from the experimental results.
