Studies of combustion reactions at the state-resolved differential cross section level (open access)

Studies of combustion reactions at the state-resolved differential cross section level

State-resolved differential reaction cross sections provide perhaps the most detailed information about the mechanism of chemical reaction, but heretofore they have been extremely difficult to measure. This program explores a new technique for obtaining differential cross sections with product state resolution. The three-dimensional velocity distribution of state-selected reaction products is determined by ionizing the appropriate product, waiting for a delay while it recoils along the trajectory imparted by the reaction, and finally projecting the spatial distribution of ions onto a two dimensional screen using a pulsed electric field. Knowledge of the arrival time allows the ion position to be converted to a velocity, and the density of velocity projections can be inverted mathematically to provide the three-dimensional velocity distribution for the selected product. The main apparatus has been constructed and tested using photodissociations. The proposed research will both develop the new technique and employ it to investigate methyl radical, formyl radical, and hydrogen atom reactions which are important in combustion processes. We intend specifically to characterize the reactions of CH{sub 3} with H{sub 2} and H{sub 2}CO; of HCO with O{sub 2}; and of H with CH{sub 4},CO{sub 2}, and O{sub 2}.

Biological processes in the water column of the South Atlantic Bight: Zooplankton responses (open access)

Biological processes in the water column of the South Atlantic Bight: Zooplankton responses

This study sought to determine and understand the major processes governing the abundance, distribution, composition and eventual fate of zooplankton on the southeastern shelf of the US in relation to water circulation. Over much of the shelf circulation is dominated by the Gulf Stream and/or atmospheric forcing. Most of our studies concentrated on processes on the middle and outer shelf. On the latter, pronounced biological production occurs year-round at frequent intervals and is due to Gulf Stream eddies which move by at an average frequency of one every week. These eddies are rich in nutrients which, when upwelled into the euphoric zone, lead to pronounced primary production which then triggers zooplankton production.

Spray nozzle pattern test for the DWPF HEME Task QA Plan. [Defense Waste Processing Facility (DWPF), High Efficiency Mist Eliminator (HEME)] (open access)

Spray nozzle pattern test for the DWPF HEME Task QA Plan. [Defense Waste Processing Facility (DWPF), High Efficiency Mist Eliminator (HEME)]

The DWPF melter off-gas systems have two High Efficiency Mist Eliminators (HEME) upstream of the High-Efficiency Particulates Air filters (HEPA) to remove fine mists and particulates from the off-gas. To have an acceptable filter life and an efficient operation, an air atomized water is spray on the HEME. The water spray keeps the HEME wet and dissolves the soluble particulates and enhances and HEME efficiency. DWPF Technical asked SRL to determine the conditions which will give satisfactory atomization and distribution of water so that the HEME will operate efficiently. The purpose of this document is to identify, QA controls to be applied in the pursuit of this task (WSRC-RP-91-1151).

Investigation of in situ hydrothermal oxidative destruction of NDMA (open access)

Investigation of in situ hydrothermal oxidative destruction of NDMA

Rate constants for the aqueous oxidation of N-nitrosodimethylamine (NDMA) have been measured in aqueous phosphate-buffered solutions using Dickson-type vessels. The initial NDMA concentrations ranged from 2.5 to 2.8 ppm and reaction temperatures varied from 180 C to 220 C. Quantitation of NDMA was performed by gas chromatography-mass spectrometry (GC-MS) using selected ion monitoring (SIM). NDMA loss with concomitant production of nitrite and nitrate confirmed that mineralization of NDMA occurred, and no intermediates amenable to GC-MS were formed during the oxidation experiments. First order reaction rate constants for the loss of NDMA were determined by the integral method and the results are as follows: k{sub 1} = 5.21 x 10{sup -7} s{sup -1} at 180 C, k{sub 1} = 1.14 x 10{sup -6} s{sup -1} at 190 C, k{sub 1} = 2.05 x 10{sup -6} s{sup -1} at 200 C, k{sub 1} = 4.53 x 10{sup -6} s{sup -1} at 210 C and k{sub 1} = 8.81 x 10{sup -6} s{sup -1} at 220 C. The Arrhenius equation for this data is listed below: ln (k) = 20.21 - 15716 (1/T). The activation energy for this process is calculated to be 130.7 {+-} 3.5 kJ/mole.

Monitoring the response of the upper troposphere/lower stratosphere to a greenhouse gas scenario. Final report, 1 May 1990--30 June 1994 (open access)

Monitoring the response of the upper troposphere/lower stratosphere to a greenhouse gas scenario. Final report, 1 May 1990--30 June 1994

A measurement system for examining the possible linkage between an increased concentration of Greenhouse Gases (GGs) and symptoms of climate change has been designed and evaluated. The system consists of a dual port emission interferometer and supporting data analysis algorithms for the remote sensing the upper troposphere/lower stratosphere from a high elevation ground site deployment. Two blackbody systems were designed and tested to provide necessary calibration targets for the interferometer. The interferometer was deployed during four different periods at climatologically distinct locations to test the capabilities of the system. Over two hundred spectra were collected in a variety of conditions ranging from a clear middle latitude atmosphere viewed from mountain site at 3.0 km ASL to sub-tropical marine stratocumulus cloudiness measured at Porto Santo Island near Madeira. The algorithm has been used successfully to retrieve temperature and moisture profiles from both the mountain and sea level deployments. These initial retrievals indicate that ground based systems may only be effective in sensing the temperature and moisture profiles for the first few kilometers above the instrument. The interferometric data have been used to estimate the size of ``equivalent spherical`` ice particles in cirrus clouds. The data from the sea level deployment were …

Nitrogen availability as a control mechanism of secondary succession within a semiarid shrubland ecosystem. Final report, October 1, 1990--June 27, 1992 (open access)

Nitrogen availability as a control mechanism of secondary succession within a semiarid shrubland ecosystem. Final report, October 1, 1990--June 27, 1992

Three experiments were conducted within a semiarid shrubland to test the role of nitrogen availability as a control mechanism in secondary succession. Secondary succession patterns were documented for seven years and effects of increased and decreased N availability levels, fumigation, and competition by early-seral species were tested. Differential responses by seral species were determined and related to successional patterns. Nitrogen availability was found to be a primary mechanism controlling the rate of succession. Relative growth rate was an important factor determining which species initially dominated and N availability became the primary control factor by the third year. As N availability increased, the rate of succession decreased. Conversely, as N availability was decreased, the rate of succession increased. The abundance of annuals was increased and abundance of perennials decreased by increased N availability. Tissue N concentration was related to lifeform and seral position, and these relationships were important in the transition from early- to mid-seral stages. Decomposer subsystem dynamics were correlated with seral community dynamics. The effect of fumigation was minimized by initially planting with late-seral species. A conceptual model of secondary succession is presented based on N availability, relative growth rate, lifeform, and decomposition dynamics.

Thermal distortion tests of aluminum and stainless steel plates (open access)

Thermal distortion tests of aluminum and stainless steel plates

An important upgrade to the STAR detector at the Brookhaven National Laboratory RHIC accelerator will be an electromagnetic calorimeter. One design being considered for this calorimeter involves cast lead modules covering {Delta}{phi} = 6{degree} and 0 {le} {vert_bar}{eta}{vert_bar} {le} 1. These modules would consist of alternating layers of lead and sheets of plastic scintillator. The gaps for scintillator between the layers of lead would be created by parallel aluminum plates of thickness {approx_equal}6.6 mm = 0.260in. in the mold for the modules. These plates would need to be machined or ground to be reasonably flat, perhaps to {plus_minus}0.003in., and of uniform thickness from plate to plate. These requirements are imposed by the need to remove the plates from the casting after cooling, and to have good uniformity of the lead layer thickness, which gives good performance for the modules as a calorimeter. Aluminum was chosen for the plates because of its high coefficient of thermal expansion. An important cost in this calorimeter design is associated with the machining or grinding of the plates to proper thickness and flatness. In most cost estimates, it has been assumed that the mold parts could be used many times. This note describes a simple …

241-U-701 new compressor building and instrument air piping analyses

Building anchorage analysis is performed to qualify the design of the new compressor building foundation given in the ECN ``241-U-701 New Compressor Building.`` Recommendations for some changes in the ECN are made accordingly. Calculations show that the 6-in.-slab is capable of supporting the pipe supports, and that the building foundation, air compressor and dryer anchorage, and electric rack are adequate structurally. Analysis also shows that the instrument air piping and pipe supports for the compressed air system meet the applicable code requirements and are acceptable. The building is for the U-Farm instrument air systems.

Coherent multiple-foil x-ray transition radiation (open access)

Coherent multiple-foil x-ray transition radiation

Intense x-ray transition radiation can be generated when relativistic electrons pass through a multiple-foil target. When the foil spacing is periodic, the transition radiation can be spatially coherent with respect to the target period. The spatial coherence can be evident in the spectra and angular distributions of transition radiation from such targets. A series of experiments has measured coherent transition radiation distributions from multiple-foil targets (up to six foils) with spacings of 50 {mu}m and 100 {mu}m. The electron energy was about 75 MeV and the photon energies were about 200 eV. Agreement between calculation and experimental data is excellent.

[Study of institutional issues relating to transportation of high level waste]. Final technical report

This is the ``seventh`` and final Quarterly Report under the scope of work for cooperative agreement between the Western Interstate Energy Board and the US Department of Energy. The report covers the period January--March 1993. The cooperative agreement was to expire in June 1992, but DOE granted an extension through March 24, 1993. Since this is the last Quarterly Report under the expired cooperative agreement, most tasks are noted as being completed. Two final items, however, will soon be sent to DOE -- final minutes from the March 9--11 High- Level Radioactive Waste Committee meeting, and the Year-End Technical Report. Some highlights from the quarter: The Committee decided on a preferred format for the revised Spent Fuel and High-Level Radioactive Waste Transportation Primer. The document would be 100- 200 pages, accompanied by a series of white papers on key transportation elements. A 25--30 page handbook for educating western state elected officials would also be prepared. On March 24, the Committee sent a letter to DOE commenting on the Near-Site Transportation Infrastructure report findings. The Committee is concerned that infrastructure limitations may limit the rail shipping option in many instances, even after upgrades have been implemented. The NSTI findings may also …
