Acoustic velocity measurement across the diameter of a liquid metal column

Description: Present techniques for measuring sound velocity in liquid metals have been limited by the use of transducers which cannot survive in extreme temperature conditions. These methods also require relatively long measurement times. An optical noncontacting method has been developed which may be used for extremely short experimental times and very high temperatures and pressures. This technique is being incorporated into an isobaric expansion apparatus in which a 1 mm diam wire sample in a high press… more

Advances in characterization of materials: alloys and ceramics

Description: The advantages of high resolution electron diffraction and imaging have been revealed in a wide variety of metallic systems, providing insight into the mechanisms of such phase transformations as ordering, spinodal decomposition, grain boundary precipitation, and the martensitic reaction. Structural discontinuities in interphase interfaces (atomic plane ledges) and grain boundaries (plane matching defects) have been identified with high precision, and compositional variations on an atomic scale… more

AGONIST-INDUCED AFFINITY ALTERATIONS OF A CENTRAL NERVOUS SYSTEM NICOTINIC ACETYLCHOLINE RECEPTOR

Description: Pretreatment of {alpha}-bungarotoxin ({alpha}-Bgt) binding sites from rat brain with cholinergic agonists causes transformation of sites to a high-affinity form toward agonist over a time course of minutes, consistent with identity of those sites as central nicotinic acetylcholine receptors (nAChR). This agonist-induced alteration in receptor state may be correlated with physiological densensitization. Agonist inhibition of toxin binding to the high-affinity state is non-competitive, suggesting… more

Analysis of a radial-outflow reaction turbine concept for geothermal application

Description: The radial-outflow reaction turbine, a pure-reaction turbine designed to improve the conversion efficiency of geothermal energy into electrical power is described. It also has potential as a total-flow turbine for low-temperature water. The principle of incomplete expansion can be used to obtain a reduction in turbine size when the turbine exhausts into a low-pressure condenser. And, by adding this turbine to single- and two-stage flashed-steam systems, the conversion efficiency of systems util… more

Analysis of airborne radiometric data. Volume 3. Topical reports

Description: This volume consists of four topical reports: a general discussion of the philosophy of unfolding spectra with continuum and discrete components, a mathematical treatment of the effects of various physical parameters on the uncollided gamma-ray spectrum at aircraft elevations, a discussion of the application of the unfolding code MAZNAI to airborne data, and a discussion of the effects of the nonlinear relationship between energy deposited and pulse height in NaI(T1) detectors.

Analysis of echo sounding data North-Central Pacific (and west North Atlantic). Final technical report, September 1, 1976--March 31, 1978. [Site selection for marine disposal of high-level radioactive wastes]

Description: Recognizing the need to consider several potentially suitable sites for disposal of high-level radioactive wastes, a very preliminary search was made through available data for such sites in the North Pacific and West North Atlantic Oceans. The criteria used were: the site must be between high-productivity belts and outside of 200 mile limit; a minimum of 50 meters of sediment, preferably 100 to 150 meters; the sediment should be red clay with minimum or no biogenic components; the sediment sho… more

Analysis of freight train accident statistics for 1972-1974

Description: Both train speed and dollar damage have been used in transportation studies as measures of accident severity. Analysis of freight train accident data for the three year period, 1972-74 showed that, in general, as speed increases dollar damage to railroad property also increases. A greater percentage of high speed than low speed accidents result in high dollar damage. Factors, in addition to speed, that can have an important effect on accident severity include the type of accident, the kinds of … more

Analysis of mixed oxide fuel irradiated in EBR-II: measured vs. predicted burnup

Description: The calculation of burnup in mixed-oxide fuel pins irradiated in EBR-II is shown to agree with burnup measured by postirradiation radiochemical analysis. The mean percent deviation is 0.12% with a variance of 2.49%. This gives a high level of confidence that HIST, which uses 91% of the nominal EBR-II power, provides an accurate estimate of burnup.

Analysis of water reinjection at the Niland Geothermal Test Site

Description: The problems associated with reinjecting spent geothermal brines are currently under investigation. This effort has included field tests of injection water to evaluate treating equipment effectiveness at the Niland Geothermal Test Loop. Membrane filter tests were conducted on fluids from the settling tanks, from the test loop, from the clarifier and at the injection well head (Magmamax No. 3). From this and other information concerning the injection interval, pressure, temperature and well hist… more

Annual environmental monitoring report, January--December 1977

Description: Environmental monitoring results continue to demonstrate that, except for penetrating radiation, environmental radiological impact due to SLAC operation is not distinguishable from natural environmantal sources. During 1977, the maximum neutron dose near the site boundary was 8.2 mrem. This represents about 8.2% of the annual dose from natural sources at this elevation, and 1.6% of the technical standard of 500 mrem per person annually.

Apparatus for testing smooth and ribbed tubing with pulsed eddy currents. [LMFBR]

Description: The use of outside diameter ribs on nuclear reactor tubing presents severe problems to nondestructive testing of this tubing. A pulsed eddy-current apparatus for inspecting the integrity of smooth and ribbed tubing has been developed at Argonne National Laboratory. Test results for this apparatus and analysis and circuit block diagrams are presented. In addition, transducer and preamplifier features, scanning procedures, and theory of operation are discussed. To date, this apparatus has provide… more

Applications of QCD. [Review]

Description: A review is given of reliable quantum chromodynamics predictions which either have or soon can be verified by experiment. Included are a discussion of the classic application of quantum chromodynamics perturbation theory and asymptotic freedom to predict scaling violations in deep inelastic leptoproduction experiments, with emphasis on the first direct experimental confirmation of the numerical values of the anomalous dimensions; a review of recent advances in developing and justifying quantum … more
