THE ACTIVITY COEFFICIENT OF AQUEOUS NaHCO{sup 3}

Description: The determination of the activity coefficient and related properties of sodium bicarbonate presents special problems because of the appreciable vapor pressure of CO{sub 2} above such solutions. With the development of reliable equations for the thermodynamic properties of mixed electrolytes, it is possible to determine the parameters for NaHCO{sub 3} from cell measurements or NaCl-NaHCO{sub 3} mixtures. Literature data are analyzed to illustrate the method and provide interim values, but it is noted that further measurements over a wider range of concentrations would yield more definitive results. An estimate is also given for the activity coefficient of KHCO{sub 3}.

Aerial Gamma Ray and Magnetic Survey Raton Basin Project. Final Report Vol. 2

Description: The Flagstaff quadrangle in northern Arizona lies at the southwestern edge of the Colorado Plateau. Portions of the Black Mesa Basin and Mogollon Rim lie within the quadrangle. Mesozoic rocks cover 90% of the surface of the Black Mesa Basin, but Paleozoic rocks dominate the Mogollon Rim. Cenozoic instrusive and extrusive rocks of the San Francisco Volcanic Field and the Hopi Buttes are superimposed on the older sedimentary sequence. Magnetic data apparently show contributions from both deep and shallow sources. The San Francisco Volcanic Field is relatively well defined, but deeper-lying structural boundaries are largely masked by the younger igneous rocks in the area. The Flagstaff quadrangle has been relatively unproductive in terms of uranium mining. Some claims are present in the Black Mesa Basin, primarily in Triassic rocks. A total of 195 groups of sample responses in the uranium window qualify as anomalies as defined in Volume I. These anomalies primarily form two distinct groups, though others are scattered throughout the quadrangle. One group is associated with igneous rocks in the northern Hopi Buttes area, and the other, a larger and more indistinct group, is primarily associated with the Shinarump Member of the Triassic Chinle Formation in the northern Painted Desert area. None are directly associated with the locations of known claims.

The American Coot (Fulica americana) on the Hanford Site Part 1: Nesting Biology

Description: The nesting biology of the American coot was studied on low-level radioactive waste ponds located on the Hanford DOE Site and on control ponds located in the Columbia National Wildlife Refuge in southeastern Washington from 1974 through 1976. The objective was to discover any differences in the nesting biology of the birds which could be attributed to the low-level radioactive wastes present in the Hanford DOE Site ponds. Coots nesting on the Hanford ponds and those nesting on the wildlife refuge were found to have similar nesting habits. Nesting habitats were similar for coots from both the control ponds and those exposed to radionuclides; all coots selected habitats in which the water level was moderate to shallow, and stable. Emergent aquatic plants such as cattail (Typha latifolia) and bulrush (Scirpus acutus) were characteristic of both habitats. There were no apparent differences in nesting chronology between birds from the different study sites; nests containing eggs were found from April through mid-June on most ponds. Clutch size showed no significant differences. The average number of eggs per nest for all ponds was 6.7. Egg and chick weights and percent hatching success were similar among coots from both study sites. Feeding habits of the coots from the two sites did show some differences. However, this is probably related to the availability of food items in each pond.

ANALYTIC POTENTIAL FUNCTIONS FOR DIATOMIC MOLECULES: SOME LIMITATIONS

Description: In discussions of the spectra of diatomic molecules, it is common in many physical chemistry and spectroscopy texts to introduce the Morse potential function V(R) = D{sub e}(1-exp(-{beta}(R-R{sub e}))) as representative of the real potential. The length scaling factor, {beta}, is usually expressed in terms of the harmonic vibration constant, {omega}{sub e}, the molecular reduced mass, {mu}, and the well depth, D{sub e}, via {beta} = k {omega}{sub e}(2{pi}{sup 2}{mu}/D{sub e}){sup 1/2} where k is a collection of physical constants appropriate to the units used for {omega}{sub e}, d{sub e}, {mu}, and {beta}. The Morse potential has the advantage that many simple, analytical expressions, such as eqn. (2), exist among the parameters of the potential function and observable spectroscopic constants.

Analytical study of TATB preheating methods

Description: TATB (1,3,5 - triamino 2,4,6 - Trinitrobenzene) is a very stable explosive that is remarkably insensitive to severe impact and thermal environment. Experiments on its initiation and detonation characteristics have found it difficult to initiate under the energy transfer of thin flyer plates accelerated by electrically exploded metal foils. Figure 1 shows the propagation of a detonation front in such an experiment. Generally, the detonation waves are confined in the region directly in front of the flyer impact surface, leaving a substantial portion of the HE undetonated. It has been suggested by Lawrence Livermore personnel that a preheated TATB charge may improve its sensitivity and thus reduce or eliminate this deficiency. The above experiments were performed at the sample temperatures ranging from -54{degrees} to +74{degrees}C. As the temperature was lowered while the flyer impact velocity remained the same, a pronounced increase in the curvature of the detonation front was observed. This results in a significant decrease in the divergence of the detonation wave. Although an accurate relationship between the wave front divergence and the sample temperature is not available, it is generally believed that, due to an accelerated rate of chemical reaction, the detonation will significantly improve at higher temperatures. It is assumed that desired results may be obtained if we preheat the TATB to 100{degrees}C at a depth of 1 cm from the flyer impact surface. Many parameters influence the methods to be considered for carrying out this HE preheating. The most important among them are the time allowed and the amount of energy available. The task is made extremely difficult by the fact that TATB is a poor thermal conductor and that deflagration occurs at around 250{degrees}C. In this study, we investigate several heating arrangements and predict the temperature distributions under prescribed boundary conditions.

Applicability of microautoradiography to sorption studies

Description: The technique of microautoradiography was applied to the study of the sorption of uranium and americium on five rock types which exist at the Nevada Test Site. It was found that autoradiograms could be prepared in a few days which would allow the specific minerals responsible for sorption to be identified. Furthermore, the state of aggregation of the sorbed species was clearly indicated. It was concluded that microautoradiography was a useful adjunct to currently used methods for studying sorption of certain radionuclides.

APPLICATION OF THE IMAGINARY TIME STEP METHOD TO THE SOLUTION OF THE STATIC HARTREE-FOCK PROBLEM

Description: A method of solution of the static Hartree-Fock problem is proposed. The method, based upon the extension of the method of solution of the time-dependent Hartree-Fock problem to imaginary time, promises to be more efficient, and applicable to more complex systems than previously proposed numerical methods.

Applications of Modern Hydrodynamics to Aeronautics. Part 1: Fundamental Concepts and the Most Important Theorems. Part 2: Applications

Description: A discussion of the principles of hydrodynamics of nonviscous fluids in the case of motion of solid bodies in a fluid is presented. Formulae are derived to demonstrate the transition from the fluid surface to a corresponding 'control surface'. The external forces are compounded of the fluid pressures on the control surface and the forces which are exercised on the fluid by any solid bodies which may be inside of the control surfaces. Illustrations of these formulae as applied to the acquisition of transformations from a known simple flow to new types of flow for other boundaries are given. Theoretical and experimental investigations of models of airship bodies are presented.

Applications of Passive Thin Films

Description: The physical properties of thin films affect the performance and durability of nearly every solar energy conversion device. Familiar examples of thin films for solar applications are optical materials and protective coatings. Optimized optical properties are key to cost-effective photothermal conversion where individual components must have high absorptance, reflectance, or transmittance. The protection of sensitive substrates from corrosion and/or erosion is essential to ensure adequate component and system lifetime. Such substrates range from photovoltaic materials operating near room temperature to turbine blade structural alloys in hostile environments at very high temperatures (>1,000 degrees C). Although much has been written on particular categories of thin-film materials for solar energy (for example, absorbers for receiver surfaces), to date no one has provided an overview of the spectrum of applications for passive thin films in solar energy. This work is such an overview and also reviews the material state of the art as described in the current literature. Active thin film devices such as photovoltaics and thermoeleetrics are not discussed.
