Heavy mass states
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
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 …

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

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

Access control system for ISABELLE
An access system based on the one now in operation at the CERN ISR is recommended. Access doors would presumably be located at the entrances to the utility tunnels connecting the support buildings with the ring. Persons requesting access would insert an identity card into a scanner to activate the system. The request would be autologged, the keybank adjacent to the door would be unlocked and ISABELLE operations would be notified. The operator would then select the door, activating a TV-audio link. The person requesting entry would draw a key from the bank, show it and his film badge to the operator who would enable the door release.

Energy use in Japan and the United States
This comparative study was undertaken to explain in part the per capita differential between the two countries. In the introduction, the ratios of energy per capita and energy per dollar of Gross Domestic Product (GDP) are presented. The exchange rates utilized to convert GDP to a common currency are discussed in detail. Brief sections on the energy supply and electric generation situation in Japan are included for background information, followed by the body of the report devoted to the energy consumption sectors. The industrial sector merits most attention because Japan's industrial capacity is second only to that of the U.S. among industrialized nations, and it is here where an intercountry comparison can reveal possibilities of technology transfer. First, a gross energy efficiency indicator for all industry (measured as industrial energy use per dollar of GDP originating in industry) is established. This is followed by detailed presentations of specific energy inputs (per ton of product) for four energy-intensive industries: iron and steel, aluminium, cement, and pulp and paper. Sections on transportation, residential, and commercial energy use reveal large differences in consumption largely due to what is labeled ''standard of living'' (housing size, automobile ownership, selection of transportation modes). Finally, the conclusions …

CDC 7600 LTSS programming stratagens: preparing your first production code for the Livermore Timesharing System
This report deals with some techniques in applied programming using the Livermore Timesharing System (LTSS) on the CDC 7600 computers at the National Magnetic Fusion Energy Computer Center (NMFECC) and the Lawrence Livermore Laboratory Computer Center (LLLCC or Octopus network). This report is based on a document originally written specifically about the system as it is implemented at NMFECC but has been revised to accommodate differences between LLLCC and NMFECC implementations. Topics include: maintaining programs, debugging, recovering from system crashes, and using the central processing unit, memory, and input/output devices efficiently and economically. Routines that aid in these procedures are mentioned. The companion report, UCID-17556, An LTSS Compendium, discusses the hardware and operating system and should be read before reading this report.

Ordered S-matrix approach to the topological expansion for baryons and mesons. [Ordered Hilbert space, Reggeon closed loops]
A proposal is made for extending to processes involving baryons the ordered Hilbert space approach to the topological expansion. The proposal is based on a topological classification scheme for baryonic processes that is similar to one used previously for the lowest-order contributions, but is in terms of the minimum number of reggeon closed loops instead of handles.

MALAPROP user's guide. [For simulating laser light propagation, for CDC7600]
MALAPROP is a CDC 7600 computer program able to simulate laser light propagation through a variety of regions. The primary program task is the integration of the partial differential equation 2in/sub 0/k/sub 0/(partial delta/partial delta z) - g(z)) psi + nabla/sup 2/ psi + 2n/sub 0//sup 2/k/sub 0//sup 2/(n/sub 2//n/sub 0/) (mod psi)/sup 2/ psi = 0 for propagation of a light beam represented by the complex array psi. This equation is computationally integrated for regions with or without gain (g(z)) and for any indices of refraction (n0,n2). In addition, the beam may be spatially filtered or relayed (using FFT methods), expanded or split or passed through an aperture (followed by a no-gain propagation region with a nonlinear index of refraction = 0). Relative amplitude or phase noise may be added to the beam at selected surfaces. Two versions exist allowing for one or two beam dimensions: one space dimension (x; propagation in z) (with saturation) and two space dimensions (x,y; propagation in z) ( without saturation). Optional output includes intensity/phase information (plots and printout), power spectral density information, computed B integral, and saturation information. Initial beam configuration is essentially limited only by array sizes. 2 tables.

Review of experiments
A study was made to examine the effects which raising the ISA from 200 x 200 GeV to 400 x 400 GeV would have on the ''canonical'' experiments. These were ''canonical'' in the sense that they span the full range of foreseeable physics and have served as topics in previous Summer Studies and Workshops which resulted in quite explicit hardware designs and experimental goals. The study results indicate that all of the ''canonical'' experiments survive. Some are actually improved, some are unaffected, and some require changes which are suggested. In general, the 90/sup 0/ experiments are relatively unaffected. The single arm small angle spectrometer, the wide aperture (FATS-WASP) spectrometer and the Coulomb interference experiment have the largest number of modifications suggested. No uniqueness to these solutions are claimed, and there may be more desirable radical approaches. It is, however, felt that the 400 x 400 GeV ISA not only permits the work on conceptual experiments from previous Summer Studies to be taken over entirely, but indicates areas of improvement in many of them. Specifics of the individual experiments are discussed.

Placental transport of radionuclides. Terminal report, May 1, 1973--July 31, 1975. [Tritiated water, tritium, /sup 14/C, /sup 45/C, and /sup 47/C tracers]
Four successful experiments were conducted with tritiated water on pregnant sheep. This came into equilibrium between fetal and maternal circulations within 60 seconds after injection into the ewe or the fetus. The estimates of total water transport rate averaged 85% of the daily water intake. Six successful experiments were conducted with /sup 3/H- and /sup 14/C-glucose on pregnant ewes. The results for glucose space and transport rate in the ewes agree closely with previously published data. The fetal glucose pool size was large, presumably reflecting the relatively large volume of fetal-placental fluids in exchange with fetal blood. Six successful experiments were conducted with /sup 45/Ca and /sup 47/Ca for 5 days or more on pregnant ewes. The smallest compartment size of exchangeable calcium in mother and fetus were about 2 to 6 hours duration, and the net daily gain of calcium by the fetus was just slightly less in the chronic than in the acute experiments, 0.75 and 0.83 g/day respectively.

Thermal and dynamic effects in electron beam welding cavities
An experimental and analytical study of the temperature distributions along the molten metal surface in an electron beam welding cavity is described. Surface temperature distributions in cavities were measured with a narrow band infrared radiation pyrometer. The availability of the cavity temperature measurements allowed estimates to be made for the vapor pressure and surface energy forces as a function of cavity position. The results indicated a force imbalance occurred in the cavity. It is postulated that at the location of the force imbalance a liquid material projection forms periodically and moves into the path of the electron beam. The liquid in this projection is driven towards the bottom, partially filling the cavity. This action is followed by the electron beam pushing the liquid aside to form a maximum depth cavity. This process is then repeated. An analysis for predicting cavity oscillation frequency shows reasonable agreement with frequencies measured at the weld root determined from weld sections. A study of the measured temperature distributions in cavities of varying depth combined with the force imbalance observations led to an interpretation of when spiking might occur. A procedure is proposed for determining the spiking tendency for a given set of weld parameters. The …
