Life-sustaining technology and the elderly: geriatric expertise in the context of critical and terminal care

Description: This report of OTA has conducted a study of a wide range of topics, some of which have recently been receiving a great deal of scrutiny inside and outside the government. In order to derive information specific enough to guide possible congressional action and to be responsive to the requesting Committees, this examination of the issues is specifically tied to particular life-sustaining technologies and their use with patients who are elderly. At the same time, much of this information is appli… more

Course Aperture Study For The Window Frame Dipoles In RHIC

Description: We use PATRICIA to study the quality of the multipolar contribution in the Window Frame Dipoles (WFD). In order to avoid possible noise with insetions, we only use 81 characteristics RHIC cell. As we want to make a comparison with available information on the Dedicated RHIC dipole (DRD), we only determine the apperture of WFD for some values of Δp/p.

The effect of target thickness on x-ray production by FXR (Flash X-Ray Machine)

Description: The electron-photon transport code SANDYL has been used to calculate the x-ray flux for a simplified Flash X-Ray Machine (FXR) bullnose geometry. Four different thicknesses (24.5, 36.75, 49, and 61.25 mils) were used for the tantalum bremsstrahlung target in order to study the effect of target thickness on the FXR output. The calculations were performed for a parallel 17 MeV electron beam, and the resulting angular distributions were then used to compute the forward flux for the more realistic … more

Computational Models of Beam Emittance Growth

Description: Two fast running computer codes have been developed to calculate and verify the predictions of phenomenological models of beam emittance growth and radial oscillation damping. This report describes the codes - a point model, EMY, and a particle simulation, DESTIN. Comparison of model predictions and simulation results is made for the cases of a beam launched near self-pinch equilibrium and for a cold beam launched in near ballistic condition.

Orbit averaged radial buildup code for tandem mirror geometry

Description: The radial Fokker-Planck (RFP) model of A. Futch was modified to treat plasma buildup in the tandem mirror plug and center cell with a self-consistent model (TOARBUC). Two major changes have been made to the original version of this code. First, the center cell is treated as having separate electron and ion confining potentials with the ion potential having the opposite sign of that in a conventional mirror. Second, a two-electron-temperature treatment derived by R. Cohen was included in the pr… more

Investigation of the Triplet State of Chlorophylls. Progress Report, May 1, 1980-April 30, 1981

Description: The triplet state of chlorophyll has been utilized as a nondestructive probe into the structural and dynamical nature of the photosynthetic apparatus. During the past year, using zero-field triplet state optically detected magnetic resonance spectroscopy, chlorophyll aggregates were examined in both their natural environment in vivo and in model complexes in vitro. Research efforts have focused on subchloroplast particles extracted from green plants, on chlorophyll monolayers, and on isolated c… more

Collection of CASIM calculations

Description: Monte Carlo calculations of hadronic cascades at Fermilab have usually been done using the code CASIM written by A. Van Ginneken. These calculations are often performed to determine the quantity of shielding required for radiation protection purposes. A number of examples of such calculations have been presented previously. Several years of practical experience have led the author to develop the collection of additional cases included in the present report. These results along with those given … more

Geothermal materials survey : Arkansas Power and Light Development and Demonstration Project. 100kW power system using direct contact heat exchangers, El Dorado, Arkansas

Description: The 100 kW plant is a direct contact boiling/direct contact condensing binary system using isopentane as the working fluid. Treated waste geothermal brine from the Great Lakes Chemical Co. (GLC) bromine recovery operation is the heat source. Brine is taken from the GLC Treated Brine Line at 205 to 210/sup 0/F and supplied to the pilot plant via the APL Brine Inlet Line. The brine enters the direct contact boiler (DCB) and vaporizes isopentane. The cooled brine is discharged into the reinjection… more

Dispersive effects of transverse magnet displacements in rolled arc achromats

Description: The effect of transverse displacements of combined function magnets is investigated where the disperion in not matched due to roll. This dispersion function is perturbed by displacement of combined function magnets either singly or coherently. In the latter case the effect of a systematic (or DC) offset of magnets is examined. This type of error can occur due to systematics in the placement or the readout of Beam Position Monitors or equivalently by correcting the orbit of a beam of the wrong m… more

D0 Vent Stacks

Description: There are two nitrogen/argon exhaust headers in the D0 cryogenic piping system, one for the liquid argon dewar and another for the three argon calorimeters. These headers serve two functions, venting both nitrogen exhaust from the cooling loops and cold argon gas should any argon vessel blow a relief. These headers are vacuum jacketed until they exit the building. At that point, uninsulated exhaust stacks direct the flow into the atmosphere. This note deals with the these stacks.

Kinetics and Mechanism of Catalytic Hydroprocessing of Components of Coal-Derived Liquids. Sixteenth Quarterly Report, February 16, 1983-May 15, 1983.

Description: A new method of structural analysis is applied to a group of hydroliquefied coal samples. The method uses elemental analysis and NMR data to estimate the concentrations of functional groups in the samples. The samples include oil and asphaltene fractions obtained in a series of hydroliquefaction experiments, and a set of 9 fractions separated from a coal-derived oil. The structural characterization of these samples demonstrates that estimates of functional group concentrations can be used to pr… more

F-111 windscreen machining. Final report

Description: Studies were conducted to determine the feasibility of improving the optical image transmitted through a military aircraft windscreen by using single-point diamond turning. Reduced warpage (waviness) of the windscreen surfaces ensures that a more accurate optical image is presented to the aircraft pilot. Machining the acrylic surface was accomplished with slightly impared image transmissibility. The use of this technique as a potential production process is discussed.

Roof-mounted solar-and-wind-powered turbine. Final report

Description: This project was an effort to convert solar energy into electricity by utilizing hot-air convection to turn a turbine. To be considered useful, such a mechanism must generate enough electricity at a cost low enough to be competitive with photovoltaics. The extraction of wind energy incidental to the solar experiment was anticipated. The mechanism constructed generates an amount of electricity so small with respect to its cost that it cannot be considered competitive with photovoltaics.

LWRHU EB weld development

Description: Electron beam weld development studies were performed for both the platinum frit vent-to-vent cap weld and also the vent cap-to-body weld for the LWRHU Project using a Hamilton Standard EBW-6 Electron Beam Welder. A total of six (6) development welds each was performed to establish welding parameters and procedures which would produce satisfactory and acceptable welds. The relatively small size of the platinum frit vent dictated that the frit-to-vent cap weld would have to be limited as to dept… more
