Evaluation of the hazard associated with fabricating beryllium copper alloys
Beryllium-copper alloys should be considered toxic materials and proper controls must be used when they are machined, heated, or otherwise fabricated. Air samples should be taken for each type of fabrication to determine the worker's exposure and the effectiveness of the controls in use. It has been shown that aerosols containing beryllium are generated during the four methods of fabrication tested, and that these aerosols can be reduced through local exhaust to undetectable levels. Considering the acute, chronic and possibly carcinogenic effects of exposure to beryllium, effective controls should be required because they are feasible both technologically and economically. The health hazards and control measures are reviewed.

Materials technology for coal-conversion processes. Eleventh quarterly report, April--June 1977
Silicon-carbide refractories with various bond systems exposed to molten slag at 1500/sup 0/C for 500 h in Run 4 showed virtually no attack. The resistance of the silicon carbide to slag attack is attributed to large thermal fluxes induced by water-cooled chills applied to the cold faces. Magnesia-chromia refractories exposed to molten slag at 1500/sup 0/C for 500 h in Run 5 were somewhat less resistant to slag attack than the silicon-carbide refractories. In-situ erosive-wear measurements on the Bi-Gas A106B low-carbon steel main coal feed line were obtained during the present quarter, with initial indications of a nominal 5% wall-thickness reduction after approximately 200 h of exposure. Acoustic leak-detection tests were carried out at the Morgantown Energy Research Center Valve Test Facility. Uniaxial tensile data were generated on several specified alloys in an as-received condition at temperatures of 750, 871, and 982/sup 0/C. A generalized approach, based on thermodynamic equilibria of gas mixtures, has been developed to evaluate the chemical potentials of the reactive elements, i.e., O, S, C, H, and N in multicomponent gas streams. The results showed that the chemical potentials can be uniquely established by the total atomic ratios C/H, C/O, and C/S in the initial gas …

Negative ion yields from protons and hydrogen atoms backscattered from cesium-coated surfaces
The formation of negative ions by hydrogen collisions on cesium-coated surfaces is discussed in the limiting cases where the resident cesium is either in the purely ionic state or in the purely atomic state. The survival fraction for negative ions moving away from a metal surface is calculated using a method employing complex eigenvalues. The fraction of surviving ions is found to be larger than calculated by previous workers. The secondary emission coefficient for negative ion production by incident atoms with energies of ten to one hundred electron volts is estimated to be in the range thirty to forty percent.

Plasma neutralizer for H/sup -/ beams
Neutralization of H/sup -/ beams by a hydrogen plasma is discussed. Optimum target thickness and maximum neutralization efficiency as a function of the fraction of the hydrogen target gas ionized is calculated for different H/sup -/ beam energies. Also, the variation of neutralization efficiency with respect to target thickness for different H/sup -/ beam energies is computed. The dispersion of the neutralized beam by a magnetic field for different energies and different values of B . z is found. Finally, a type of plasma jet is proposed, which may be suitable for a compact H/sup -/ neutralizer.

The use of the semantic differential in a study of the effects of aspirational and dissociative reference group influence on consumer behavior
The purpose of this study was to investigate the effects of aspirational and dissociative reference group influence on consumer behavior. There are two ways in which behavior is influenced by reference groups. First, reference groups influence aspiration levels and therefore play a major role in producing satisfaction or frustration. Second, reference groups influence kinds of behavior, i.e., they establish approved patterns of behavior.

Walker Branch Watershed: site description and research scope
Walker Branch Watershed is located on the Oak Ridge Reservation in the Ridge and Valley section of Tennessee. The watershed (97 ha consisting of 2 subwatersheds) is underlain by Knox Dolomite; soils formed over the dolomitic substrate are deep, well-drained Typic Paleudults. The watershed is forested. The overstory is predominantly oak-hickory with lesser amounts of pine and mesic hardwoods. The Walker Branch Watershed Project was initiated in 1967 to: relate the productivity and water quality of the stream to the productivity and nutrient balance of the adjacent terrestrial ecosystem; relate the net loss of nutrient elements to the rate of nutrient cycling; define the relationship between the hydrologic cycle and nutrient flux; provide benchmark information on natural terrestrial-aquatic ecosystems for comparison with man-modified situations; and to enable the measurement of environmental degradation caused by man's cultural practices. Research has been completed or is on-going in several distinct, but related, areas: ecosystem analysis of essential element dynamics (N, P, K, Ca, Mg and C), atmospheric and hydrologic input-output processes, trace element biogeochemistry (e.g., Cd, Pb, Zn) and sulfur. Research objectives have been approached by analysis of the role of important biological and physical processes, and the development of mathematical models.

Thermal expansion of molten materials by the gamma attenuation technique
An apparatus was constructed for measurement of the density and volumetric thermal expansion of high temperature molten materials using the gamma attenuation technique. It was found that significant improvements in overall experimental precision could be realized by employing an automatic gain control in the linear section of the gamma counting system. This device reduced errors due to system gain shifts and thereby increased the precision of the gamma counting. Corrections were also made for the dead time of the electronics system. A preliminary experimental investigation of the precision of the method was made by measuring small dimensional steps of a tool steel block at a single temperature. A fractional length increment ..delta..l/l of 1% was determined to 1%, equivalent to a length change precision of 10/sup -4/ cm/cm. In addition, the precision of the experimental technique was analytically examined for both absolute and relative density determinations. Three analytical expressions used to reduce data for liquid density determinations were evaluated for their precision. Each allows use of a different set of input data parameters, which can be chosen based on experimental considerations. Using experimentally reasonable values for the precision of the parameters yields a similar resultant density precision from the three …

Formation processes and secondary emission coefficients for H/sup -/ production on alkali-coated surfaces
The formation of negative ions by hydrogen collisions on cesium-coated surfaces is discussed in the limiting cases where the resident cesium is either in the purely ionic state or in the purely atomic state. The survival fraction for negative ions moving away from a metal surface is calculated using a method employing complex eigenvalues. The fraction of surviving ions is found to be larger than calculated by previous workers. The secondary emission coefficient for negative ion production by incident atoms with energies of ten to one hundred electron volts is estimated to be in the range thirty to fifty percent. The secondary emission coefficient is found to be a sensitive function of the thickness of the alkali adsorbate coating for ion energies in the range below a few hundred electron volts.

A study of the perceptions of presidents and academic deans regarding role expectations and decision-making styles of academic deans in Texas community colleges
The purpose of this study was to determine whether similarities exist in the perceptions of the roles of academic deans in community colleges. This study attempted to determine whether role expectations and perceptions reflected separate and distinct relationships, or if administrative patterns reflected an overlapping of responsibilities.
