Mutagenicity of six mild gasification product samples was studied using the Ames Salmonella/microsomal assay system. The results of the Ames testing of the MG-119 and MG-120 subfractions indicate significant mutagenic activity only in the nonpolar neutral fraction. The activity was evident on bacterial strains, TA98 and TA100, with and without metabolic activation for MG-120, and with metabolic activation for MG-119. Previous testing of MG-119 and MG-120 when solvated in DMSO had shown possible, but unconfirmable, mutagenic activity. Tween 80-solvated MG-119 and MG-120 showed low, but significant, mutagenic activity only on TA98 with metabolic activation. Comparison of these results indicate an inhibition of the mutagenic components by nonmutagenic components in the complex mixture. 4 refs., 2 tabs.

The DO cryogenic system is controlled by a TI565-PLC based control system. This allows the system to be unmanned when in steady state operation. System experts will need to be contacted when system parameters exceed normal operating points and reach alarm setpoints. The labwide FIRUS system provides one alarm monitor and communication link. An autodialer provides a second and more flexible alarm monitor and communication link. The autodialer monitors contact points in the control system and after receiving indication of an alarm accesses a list of experts which it calls until it receives an acknowledgement. There are several manufacturers and distributors of autodialer systems. This EN explains the search process the DO cryo group used to fmd an autodialer system that fit the cryo system's needs and includes information and specs for the unit we chose.

The purpose of this analysis is to outline and recommend two standby generator systems. These systems shall provide power during a utility outage to critical Alcove No.5's thermal test loads and to subsurface flow through ventilation loads. Critical loads that will be supported by these generator systems will be identified and evaluated. Additionally, other requirements from the Exploratory Studies Facilities Design Requirements (ESFDR) document will be evaluated. Finally, the standby generator systems will be integrated into the existing ESF subsurface distribution system. The objective of this analysis is to provide design inputs for an efficient and reliable standby generator systems which will provide power for critical loads during a power outage; specifically, Alcove No.5's thermal test loads and the subsurface flow through ventilation loads. Additionally, preliminary one-line diagrams will be developed using this analysis as a primary input.

In this article, recent measurements made with LIFTIRS, the Livermore Imaging Fourier Transform InfraRed Spectrometer, are presented. The experience gained with this instrument has produced a variety of insights into the tradeoffs between signal to noise ratio (SNR), spectral resolution and temporal resolution for time multiplexed Fourier transform imaging spectrometers. This experience has also clarified the practical advantages and disadvantages of Fourier transform hyperspectral imaging spectrometers regarding adaptation to varying measurement requirements on SNR vs. spectral resolution, spatial resolution and temporal resolution.

The electronic transference numbers of BCY were relatively low when compared with the protonic numbers. At 800 C, a hydrogen flux of only 0.02 cm{sup 3}/min/cm{sup 2} was obtained in an {approx} 2-rnm-thick BCY sample by short-circuiting the two Pt electrodes. We have developed a novel composite system with improved electronic transport, and preliminary measurements indicate that the new membrane materials can be used in a nongalvanic mode to separate hydrogen from gas mixtures. A maximum flux of 0.12 cm{sup 3}/min/cm{sup 2} has been measured at 800 C in the composite material operated in the nongalvanic mode. Currently, work is underway to further enhance the hydrogen flux in the composite membrane materials.

Flywheels are being developed for use in an Advanced Locomotive Propulsion System (ALPS) targeted for use in high speed passenger rail service. The ALPS combines high performance, high speed gas turbines, motor/generators and flywheels to provide a light-weight, fuel-efficient power system. Such a system is necessary to avoid the high cost of railway electrification, as is currently done for high speed rail service (>100mph) since diesels are too heavy. The light-weight flywheel rotors are made from multilayered composite materials, and are operated at extremely high energy levels. Metal containment structures have been designed to enclose the rotors and provide encapsulation of the rotor during postulated failure events. One such event is a burst mode failure of the rotor in which the composite rim is assumed to burst into debris that impacts against the containment. This paper presents a finite element simulation of the transient structural response of a subscale metal flywheel containment structure to a rotor burst event.

The process control SO{sub x}, NO{sub x}, and particulate emission from coal combustion flue gases. It is based on a solid-state, electrochemical reactor which converts NO{sub x} and SO{sub 2} to nitrogen, sulfur, and oxygen. Sulfur is condensed downstream at a lower temperature. Particulates are removed with a filter or electrostatic precipitator. The process utilizes no other material input (flue gas is the only fluid), has no moving parts, and produces no sludge(s). The reactor consists of an electrochemical cell where the electrolyte is a solid oxygen ion conducting ceramic such as stabilized ceria or zirconia and the electrodes are electronically conductive material(s). Porous metal such as silver or gold were used as electrodes in the experimental work. Acceptable reduction rates and electric power requirements for sulfur dioxide and nitrogen oxide removal were obtained in up to 1% oxygen with ruthenium and strontium ruthenate electrocatalysts. Electrocatalytic improvements are needed for higher oxygen concentrations, with the NO reduction rates and efficiencies being most sensitive to oxygen concentration. The best electrocatalysts were ruthenium and the perovskite strontium ruthenate. 37 refs., 23 figs., 26 tabs.

This paper documents the results of a sequence of tests conducted to evaluate the DoD Computer-aided Acquisition and Logistic Support (CALS) data interchange capability of the Air Force Engineering Data Computer-Assisted Retrieval System (EDCARS). The CALS initiative specifies a standard digital interface to streamline the interchange of technical data between the DoD and the commercial sector. The CALS Test Network (CTN) is tasked to conduct tests of military standards which specify this digital interface. The testing results outlined in this report are intended to evaluate the EDCARS systems`s ability to sport CALS data interchanges and establish the level of technical data interoperability implemented at this DoD engineering data repository.

The OJI supported research of J. Ellison has been concentrated in two areas: study of W{gamma} and Z{gamma} production at the Tevatron, which probes the trilinear boson coupling; design, fabrication and testing of silicon microstrip detectors for the D0 upgrade silicon tracking system. The W{gamma} analysis using data from the first D0 run ({approximately}14 pb{sup {minus}1} integrated luminosity) has been completed - J. Ellison and a postdoctoral research working with him (B. Choudhary) were responsible for the muon channel analysis. This analysis is an important test of the Standard Model (SM), since it probes the nature of the WW{gamma} coupling, which is related to the W boson magnetic dipole and electric quadrupole moments. Any deviation from the SM value of the WW{gamma} coupling would be an indication of either composite structure of the W or higher order loop corrections involving physics beyond the SM. The analysis has resulted in the world`s most sensitive limits on the WW{gamma} coupling parameters. In addition the author has also worked on an analysis of Z{gamma} production which has yielded sensitive limits on the ZZ{gamma} and Z{gamma}{gamma} couplings. The work on the D0 Silicon Tracker has also made very good progress. The team led by …

To provide generic methodology for discrete-event simulation of manufacturing processes, object-oriented programming techniques have been employed to aid in code clarity, efficient development, and maintenance. This paper discusses the interaction between objects. The objects are independent of one another relative to internal coding, but maintain a standard communication protocol. Specific examples using the Rocky Flats Plant Simulation developed by group A-7 are presented. 3 refs., 1 fig.

The People's Republic of China (PRC)'s provocative use of military force in the Taiwan Strait has appeared to subside, but not before convincing many in the Congress that the PRC regime continues to flout international norms sensitive to the United States. In addition to challenging stability in the Taiwan Strait, the PRC is seen recently to undermine important U.S. interests regarding nuclear proliferation, intellectual property rights, and missile proliferation. As a result, many in the Congress are pressing for actions -- including economic and other sanctions

An electrostatically-actuated polyimide microvalve is developed with sub-micron gaps between the electrodes to provide high force with low power consumption (< 1 mW). Built-in residual stress results in a curled bimorph cantilever which allows for a n-Licroactuator with large displacement. This microactuator is used to open and close a fluid path hole etched in silicon for a microvalve. The microactuator can be actuated with 25V for a displacement of 200 {mu}m. The cantilever actuator is mainly composed of polyimide, which is flexible enough to conform over the flow hole, thereby eliminating the need for the design of a valve seat.

In the first quarter report, comparison was made between measured water compositions obtained from Hole 16, interval 4 (16-4), and preliminary simulations of that water chemistry. This report describes additional data collected since that sampling, as well as the results of refined simulations that provide a better approximation of the reaction path followed by the water. Also, during this period waters were extracted from pads placed on SEAMIST liners in boreholes specifically for chemical sampling. Several pads exhibited evidence of having collected moisture, so they were removed and the water analyzed. However, for reasons discussed below, analytical problems were encountered. As a result, refined sampling techniques will be used in the future Drift Scale Test, when employing sample pads on the liners.

An Er:YAG laser, operating at 2.94 microns, has been developed for in-theater calibration of space based infrared sensors. The laser is used to illuminate a spaceborne sensor focal plane from a surveyed ground reference point. The known reference point is compared to the laser position reported by the sensor, and boresight corrections are made. The Er:YAG laser is side pumped by a InGaAs diode array and is tuned to an atmospheric microwindow with and intracavity etalon. This technology is being directly applied to meet Army requirements for enhanced deep strike targeting information supplied to theater weapons systems.
