Biological sample preparation and {sup 41}Ca AMS measurement at LLNL (open access)

Biological sample preparation and {sup 41}Ca AMS measurement at LLNL

Calcium metabolism in biology may be better understood by the use of {sup 41}Ca labels, although detection by accelerator mass spectrometry (AMS) is required. Methodologies for preparation of urine samples and subsequent AMS measurement were investigated. Novel attempts at preparing CaH{sub 2} were unsuccessful, but CaF{sub 2} of sufficient purity could be produced by precipitation of calcium from urine as oxalate, followed by separation of calcium by cation exchange chromatography and washing the CaF{sub 2} precipitate. The presence of some remaining impurities could be compensated for by selecting the appropriate accelerated ion charge state for AMS. The use of projectile x rays for isobar discrimination was explored as an alternative to the conventional dE/dx device.

Cell synchrony and chromosomal protocols for somatic cells of cotton gossypium hirsutum (open access)

Cell synchrony and chromosomal protocols for somatic cells of cotton gossypium hirsutum

The intent of this pamphlet is to share information with others who are interested in useful protocols for cotton cytogenetics and cytology. The protocols described are a beginning effort and they are expected to be improved. All methods, results and data given pertain to cultivar MD 51ne. We are not satisfied with our results of in situ hybridization.

Characterization of hazardous constituents in HLW supernate and implications for solid LLW generation (open access)

Characterization of hazardous constituents in HLW supernate and implications for solid LLW generation

High Level Waste (HLW) generated during Separations processing in the F- and H-Canyons is transferred to the Tank Farms for stage in 51 underground, million gallon storage tanks. The waste is an aqueous solution containing dissolved sodium salts and insoluble metal oxides/hydroxides. The waste solution is evaporated to reduce the volume, and the resulting saltcake and residual supernate are stored. Over the 40 year history of the Tank Farm, routine supernate sampling has been conducted in support of the primary goal of safe storage of HLW. As a result of routine and non-routine activities that are part of managing these highly radioactive wastes, secondary solid waste is generated. Radioactive contamination of over 90% of the solid waste generated is due to contact with BLW supernate or saltcake. In order to comply with the Waste Acceptance Criteria (WAC) for of solid waste in the E-Area Vaults (EAV), the quantity of certain radioisotopes must be manifested for each waste container and a declaration made of whether or not the waste is hazardous. However, solid waste is not amenable to routine analysis, this forces a reliance on analytical data from supernate samples to characterize the contamination. To provide the manifest information, process knowledge …

Engineering scale mixing system tests for MWTF title II design (open access)

Engineering scale mixing system tests for MWTF title II design

Mixing tests for the Multifunction Waste Tank Facility (MWTF) were conducted in 1/25 and 1/10 scale test tanks with different slurry levels, solids concentrations, different jet mixers and with simulated in-tank structures. The same test procedure was used as in the Title I program, documented in WHC-SD-W236A-ER-005. The test results support the scaling correlation derived previously in the Title I program. The tests also concluded that a partially filled tank requires less mixing power, and horizontal and angled jets in combination (H/A mixer) are significantly more effective than the two horizontal jet mixers (H/H mixer) when used for mixing slurry with a high solids concentrations.

[The front entrance of the Sinclair building in Fort Worth]

Photograph of the entrance to the Sinclair building in Fort Worth, located at 512 Main Street. The building is in the Art Deco style. The entrance has a geometric archway in the shape of a step-pyramid. The arch is symmetrical with five distinct sections of decoration. The outer two sections are the smallest and feature a metal flower with geometric leaves on its stem. The inner two have what appears to be reminiscent of a fountain, also made out of metal. The center section of the archway has a variety of geometric patterns and shapes made out of thin metal. The band at the bottom of the arch, separating it from the building's identifier, is filled with triangular shapes. The building's name is written on polished marble, and it reads "SINCLAIR BUILDING." There are two sets of double doors below this, each with large metal kickplates. Shrubs sit in pots on either side of the entrance. There are multiple plaques on the walls by the arch, along with a sconce light.

GMS/DACS interface acceptance test report (open access)

GMS/DACS interface acceptance test report

The DACS, which is housed in a trailer located just outside of the north fence at the SY tank farm, receives input signals from a variety of sensors located in and around the SY-101 tank. These sensors provide information such as: tank vapor space and ventilation system H{sub 2} concentration; tank waste temperature; tank pressure; waste density; operating pump parameters such as speed, flow, rotational position, discharge pressure, and internal temperature; strain (for major equipment); and waste level. The output of these sensors is conditioned and transmitted to the DACS computers where these signals are displayed, recorded, and monitored for out-of-specification conditions. If abnormal conditions are detected, then, in certain situations, the DACS automatically generates alarms and causes the system to abort pump operations. The portions of the system to be tested include: new RGA5 gas monitor; existing gas chromatographs; FTIR; B and K (Photo) NH{sub 3} equipment; any new or changed Genesis screens; and I/O Drop 13.

Loch Linnhe experiment 1994: Background stratification and shear measurements. Part 1: Profile summary and dispersion relations (open access)

Loch Linnhe experiment 1994: Background stratification and shear measurements. Part 1: Profile summary and dispersion relations

This report documents water column measurements made during the 1994 Loch Linnhe experiment, a joint US/UK radar ocean imaging experiment. Part 1 summarizes the profiles of temperature, salinity, density, Brunt-Vaisala frequency, and horizontal currents resolved into along and cross track directions. Internal wave dispersion relations, phase and group velocities, and eigenfunctions for modes 1 and 2 are computed for each profile. The effect of depth on these derived internal wave parameters is examined as well by computing eigenvalues and eigenfunctions for two different depths. The trials were conducted in Loch Linnhe, Scotland during the period from September 4, 1994 to September 17, 1994. The measurements reported herein were made from on board the R. V. Calanus, a research vessel operated by the Dunstaffnage Marine Laboratory (DML). The Calanus was moored approximately 125 meters from the track of the wake generating ship, either the R. V. Colonel Templer or a {open_quotes}Dog{close_quotes} class tug, the Collie. The depth at the mooring location was approximately 45 meters, while the depth at the closest point along the ship track was approximately 80 meters. For further details of the experiment, one is referred to the Loch Linnhe Experiment 1994: Trial Plan, Draft Version 3.0.

Low Temperature SO{sub 2} Removal With Solid Sorbents in a Circulating Fluidized Bed Absorber. Final Report (open access)

Low Temperature SO{sub 2} Removal With Solid Sorbents in a Circulating Fluidized Bed Absorber. Final Report

A novel flue gas desulfurization technology has been developed at the University of Cincinnati incorporating a circulating fluidized bed absorber (CFBA) reactor with dry sorbent. The main features of CFBA are high sorbent/gas mixing ratios, excellent heat and mass transfer characteristics, and the ability to recycle partially utilized sorbent. Subsequently, higher SO{sub 2} removal efficiencies with higher overall sorbent utilization can be realized compared with other dry sorbent injection scrubber systems.
