Heavy mass states

Description: The indirect evidence for the production of a heavy lepton and direct evidence for the product of a new hadronic state or states in proton-proton interactions is considered for the interpretation requiring the existence of two more leptons and two new quarks. It is shown that such a picture is consistent and in good agreement with existing data. The new structure is located at M = 9.54 GeV/c/sup 2/ and is much wider than the experimental resolution. Also it is asymmetric, suggesting the presence of several resonances. 7 references. (JFP)

Hydrogen bonding in asphaltenes and coal. Progress report, March 1, 1977--August 31, 1977

Description: A calorimetric method is presented for the simultaneous evaluation of equilibrium constant, K, and molar enthalpy, ..delta..H/sup 0/, for 1 : 1 adduct formation of quinoline (Qu) with asphaltene (A), together with its acid/neutral (AA) fraction and its base (BA) fraction, isolated from a centrifuged liquid product (CLP) sample prepared from Kentucky hvAb coal at 27.6 MPa hydrogen pressure and 723K, with reactor charged with glass pellets. The same procedure was used to determine K and ..delta..H/sup 0/ for 1 : 1 adduct formation of Qu with asphaltene and heavy oils obtained from CLP samples (FB-53) prepared with CoMo catalyst at different run times and process conditions. The effects of the CoMo catalyst, run time, and residence times on viscosity, molecular weight, ..delta..H/sup 0/, heteratom content, contents of preasphaltene, asphaltene and heavy oil, aromaticity, and structural parameters, are determined. These findings lead to the conclusion that hydrogen bonding plays an important role in determining viscosity, and contributes more to the enthalpy of interaction than does ..pi..-interaction. The toluene-insoluble fraction, asphaltene (whole, acid/neutral and base fractions), and heavy oil were isolated from a solvent-refined-coal (SRC) conversion product. Data obtained from several infrared and viscosity experiments indicate that the behavior of different fractions isolated from SRC is similar to that of corresponding fractions isolated from CLP samples.

Environmental monitoring at major U. S. Energy Research and Development Administration contractor sites: calendar year 1976. Volume 2

Description: The purpose of this compilation is to present, in a central reference document, all of the individual annual reports summarizing the results of the environmental monitoring programs conducted at each of the Energy Research and Development Administration (ERDA) sites having a potential for environmental impact or which release a significant quantity of radioactivity or nonradioactive pollutants. Data on the levels of radioactivity and nonradioactive pollutants in effluents and the environs at each site are given, and effluent and environmental measurements and sampling results are evaluated in relation to the appropriate standards for environmental protection, including estimates of potential radiation exposures offsite. It is noteworthy that, in most cases, the potential offsite exposures are so low they cannot be determined by direct measurement methods but must be estimated by calculational techniques. All potential offsite exposures to members of the public from routine effluent releases in 1976 were less than 5 mrem/yr (i.e., less than one percent of the established radiation protection guidelines for exposure of the public). Additionally, the estimated collective man-rem dose potential to all members of the public within an 80 Km radius at all ERDA sites is less than .02 percent of the estimated man-rem dose due to natural and background environmental radiation.

Stirling total energy systems study. Final report, May 15, 1976--June 13, 1977

Description: The application of Stirling cycle prime movers to total energy power generation systems was investigated. Electrical, heating, and cooling demand profiles for a typical residential complex, hospital, and office building were studied, and alternative Stirling total energy systems were conceptualized for each site. These were analyzed in detail and contrasted with purchased-power systems for these sites to determine fuel-energy savings and investment attractiveness. The residential complex and hospital would be excellent candidates for total energy systems, and prime movers in the 1000 kW output range would be required. Stirling engines with so large an output have not been built to date, although there would be no fundamental technical barrier to prevent this. However, careful consideration must be given to the following technological decision areas before arriving at a final design, if its potential is to be realized: engine configuration, hotside heat exchange interface, engine control system, internal gas seals, and advanced coal combustion technology. The principal advantage of a Stirling prime mover in this application, in view of national concern over present and future dependence on oil, is that it could utilize low-grade liquid fuels and coal.

Physicochemical Studies of the Carbamate-CO/sub 2/-Solvent System

Description: The formation of carbamate from CO/sub 2/ and the various amine solutions has been investigated for the purpose of elucidating the structure of the species generated in the reaction. The amine solutions used were 1 and 2 molar solutions of di-n-butylamine (DNBA) in triethylamine (TEA), pure DNBA and pure TEA. It has been found that the nonaqueous solvent participates in the formation of carbamate in 1 and 2M-DNBA/TEA solutions as a proton acceptor in DNBA-carbamate formation. However, due to the high concentration of the solutions and the basicities of the amines, a significant amount of DNBA which does not form the DNBA-carbamate anion is also found to be participating as a proton acceptor. Pure TEA absorbs only /sup 1///sub 60/ of the absorption by pure DNBA. The extent of TEA participation in the CO/sub 2/-absorption process other than as a proton acceptor in DNBA-carbamate is negligible. The formation of carbamic acid and zwitterion have been found unlikely. 7 tables, 15 figs.

Measurement and analysis of flow wall shear stress in an interior subchannel of triangular array rods. [LMFBR]

Description: A simulated model of triangular array rods with pitch to diameter ratio of 1.10 (as a test section) and air as the fluid flow was used to study the LMFBR hydraulic parameters. The wall shear stress distribution around the rod periphery, friction factors, static pressure distributions and turbulence intensity corresponding to various Reynolds numbers ranging from 4140 to 36170 in the central subchannel were measured. Various approaches for measurement of wall shear stress were compared. The measurement was performed using the Preston tube technique with the probe outside diameter equal to 0.014 in.

Optimal Linfinity estimates for some Galerkin methods for the Dirichlet problem

Description: Optimal L/sup infinity/ error estimates are established for a few different finite-element-type methods for the Dirichlet problem in a bounded domain. The methods are selected so as to avoid the necessity of imposing boundary conditions on the trial functions, usually difficult in practice. Three specific methods are treated. These are the method of interpolated boundary conditions and two methods of Nitsche. The trial spaces, S/sup h/, consist of continuous piecewise polynomials of degree less than or equal to K-1 with K greater than 2. The model problem treated is -..delta.. ..-->.. u = f in ..cap omega.., u = 0 on delta..cap omega.., ..cap omega.. contained in R/sup 2/. For each method, an approximate solution, u/sup h/, is constructed for h sufficiently small. The main result of this report states that the following error estimate holds for each method: norm (u--u/sup h/)/sub L/sup infinity/(..cap omega..)/ less than or equal to Ch/sup K/norm(u)/sub W/sub infinity//sup K/(..cap omega..)/.

Cryogenic recovery analysis of forced flow supercritical helium cooled superconductors

Description: A coupled heat conduction and fluid flow method of solution was presented for cryogenic stability analysis of cabled composite superconductors of large scale magnetic coils. The coils are cooled by forced flow supercritical helium in parallel flow channels. The coolant flow reduction in one of the channels during the spontaneous recovery transient, after the conductor undergoes a transition from superconducting to resistive, necessitates a parallel channel analysis. A way to simulate the parallel channel analysis is described to calculate the initial channel inlet flow rate required for recovery after a given amount of heat is deposited. The recovery capability of a NbTi plus copper composite superconductor design is analyzed and the results presented. If the hydraulics of the coolant flow is neglected in the recovery analysis, the recovery capability of the superconductor will be over-predicted.
