Monitored Natural Attenuation of Chlorinated Solvents - Moving Beyond Reuctive Dechlorination  

SciTech Connect (OSTI)

Monitored natural attenuation (MNA), while a remedy of choice for many sites, can be challenging when the contaminants are chlorinated solvents. Even with many high quality technical guidance references available there continue to be challenges implementing MNA at some chlorinated solvent sites. The U.S. Department of Energy, as one organization facing such challenges, is leading a project that will incorporate developing concepts and tools into the existing toolbox for selecting and implementing MNA as a remediation option at sites with chlorinated solvents contamination. The structure and goals of this project were introduced in an article in the Winter 2004 issue of Remediation (Sink et al.). This article is a summary of the three technical areas being developed through the project: mass balance, enhanced attenuation, and characterization and monitoring supporting the first two areas. These topics will be documented in separate reports available from the US Department of Energy Office of Scientific and Technical Information at www.osti.gov.

Inverse natural convection problem of estimating wall heat flux using a moving sensor  

SciTech Connect (OSTI)

Inverse heat transfer problems have many applications in various branch of science and engineering. Here, the inverse problem of determining heat flux at the bottom wall of a two-dimensional cavity from temperature measurement in the domain is considered. The Boussinesq equation is used to model the natural convection induced by the wall heat flux. The inverse natural convection problem is posed as a minimization problem of the performance function, which is the sum of square residuals between calculated and observed temperature, by means of a conjugate gradient method. Instead of employing several fixed sensors, a single sensor is used which is moving at a given frequency over the bottom wall. The present method solves the inverse natural convection problem accurately without a priori information about the unknown function to be estimated.

Moving zone Marangoni drying of wet objects using naturally evaporated solvent vapor  

DOE Patents [OSTI]

A surface tension gradient driven flow (a Marangoni flow) is used to remove the thin film of water remaining on the surface of an object following rinsing. The process passively introduces by natural evaporation and diffusion of minute amounts of alcohol (or other suitable material) vapor in the immediate vicinity of a continuously refreshed meniscus of deionized water or another aqueous-based, nonsurfactant rinsing agent. Used in conjunction with cleaning, developing or wet etching application, rinsing coupled with Marangoni drying provides a single-step process for 1) cleaning, developing or etching, 2) rinsing, and 3) drying objects such as flat substrates or coatings on flat substrates without necessarily using heat, forced air flow, contact wiping, centrifugation or large amounts of flammable solvents. This process is useful in one-step cleaning and drying of large flat optical substrates, one-step developing/rinsing and drying or etching/rinsing/drying of large flat patterned substrates and flat panel displays during lithographic processing, and room-temperature rinsing/drying of other large parts, sheets or continuous rolls of material.

Phenomenology of turbulent dynamo growth and saturation  

E-Print Network [OSTI]

With a non local shell model of magnetohydrodynamic turbulence we investigate numerically the turbulent dynamo action for low and high magnetic Prandtl numbers ($Pm$). The results obtained in the kinematic regime and along the way to dynamo saturation are understood in terms of a phenomenological approach based on the local ($Pm\\ll 1$) or non local ($Pm\\gg 1$) nature of the energy transfers. In both cases the magnetic energy grows at small scale and saturates as an inverse `` cascade ''.

Some Boussinesq Equations with Saturation  

SciTech Connect (OSTI)

We investigate numerically some Boussinesq type equations with square or cubic and saturated nonlinearity. We examine the propagation, interaction and overtake interaction of soliton solutions. Moreover, we examine the effect of the saturation term on the solution and compare it with the classical case of the square or cubic nonlinearity without saturation. We calculate numerically the phase shift experienced by the solitons upon collision and conclude the impact of saturation.

SATURATED ZONE IN-SITU TESTING  

SciTech Connect (OSTI)

The purpose of this scientific analysis is to document the results and interpretations of field experiments that test and validate conceptual flow and radionuclide transport models in the saturated zone (SZ) near Yucca Mountain, Nevada. The test interpretations provide estimates of flow and transport parameters used in the development of parameter distributions for total system performance assessment (TSPA) calculations. These parameter distributions are documented in ''Site-Scale Saturated Zone Flow Model (BSC 2004 [DIRS 170037]), Site-Scale Saturated Zone Transport'' (BSC 2004 [DIRS 170036]), Saturated Zone Colloid Transport (BSC 2004 [DIRS 170006]), and ''Saturated Zone Flow and Transport Model Abstraction'' (BSC 2004 [DIRS 170042]). Specifically, this scientific analysis contributes the following to the assessment of the capability of the SZ to serve as part of a natural barrier for waste isolation for the Yucca Mountain repository system: (1) The bases for selection of conceptual flow and transport models in the saturated volcanics and the saturated alluvium located near Yucca Mountain. (2) Results and interpretations of hydraulic and tracer tests conducted in saturated fractured volcanics at the C-wells complex near Yucca Mountain. The test interpretations include estimates of hydraulic conductivities, anisotropy in hydraulic conductivity, storativities, total porosities, effective porosities, longitudinal dispersivities, matrix diffusion mass transfer coefficients, matrix diffusion coefficients, fracture apertures, and colloid transport parameters. (3) Results and interpretations of hydraulic and tracer tests conducted in saturated alluvium at the Alluvial Testing Complex (ATC) located at the southwestern corner of the Nevada Test Site (NTS). The test interpretations include estimates of hydraulic conductivities, storativities, total porosities, effective porosities, longitudinal dispersivities, matrix diffusion mass transfer coefficients, and colloid transport parameters. (4) Comparisons of sorption parameter estimates for a reactive solute tracer (lithium ion) derived from the C-wells field tracer tests and laboratory tests using C-wells core samples. (5) Sorption parameter estimates for lithium ion derived from laboratory tests using alluvium samples from ATC well NC-EWDP-19D. These estimates will allow a comparison of laboratory- and field-derived sorption parameters to be made in saturated alluvium if cross-hole tracer tests are conducted at the ATC.

Site-Scale Saturated Zone Flow Model  

SciTech Connect (OSTI)

The purpose of this model report is to document the components of the site-scale saturated-zone flow model at Yucca Mountain, Nevada, in accordance with administrative procedure (AP)-SIII.lOQ, ''Models''. This report provides validation and confidence in the flow model that was developed for site recommendation (SR) and will be used to provide flow fields in support of the Total Systems Performance Assessment (TSPA) for the License Application. The output from this report provides the flow model used in the ''Site-Scale Saturated Zone Transport'', MDL-NBS-HS-000010 Rev 01 (BSC 2003 [162419]). The Site-Scale Saturated Zone Transport model then provides output to the SZ Transport Abstraction Model (BSC 2003 [164870]). In particular, the output from the SZ site-scale flow model is used to simulate the groundwater flow pathways and radionuclide transport to the accessible environment for use in the TSPA calculations. Since the development and calibration of the saturated-zone flow model, more data have been gathered for use in model validation and confidence building, including new water-level data from Nye County wells, single- and multiple-well hydraulic testing data, and new hydrochemistry data. In addition, a new hydrogeologic framework model (HFM), which incorporates Nye County wells lithology, also provides geologic data for corroboration and confidence in the flow model. The intended use of this work is to provide a flow model that generates flow fields to simulate radionuclide transport in saturated porous rock and alluvium under natural or forced gradient flow conditions. The flow model simulations are completed using the three-dimensional (3-D), finite-element, flow, heat, and transport computer code, FEHM Version (V) 2.20 (software tracking number (STN): 10086-2.20-00; LANL 2003 [161725]). Concurrently, process-level transport model and methodology for calculating radionuclide transport in the saturated zone at Yucca Mountain using FEHM V 2.20 are being carried out in the model report, ''Site-Scale Saturated Zone Transport'', MDL-NBS-HS-000010 Rev 01 (BSC 2003 [162419]). The velocity fields are calculated by the flow model, described herein, independent of the transport processes, and are then used as inputs to the transport model. Justification for this abstraction is presented in the model report, ''Saturated Zone Flow and Transport Model Abstraction'', MDL-NBS-HS-000021 (BSC 2003 [164870]).

Saturable absorption and 'slow light'  

E-Print Network [OSTI]

Quantitative evaluation of some recent 'slow light' experiments based on coherent population oscillations (CPO) shows that they can be more simply interpreted as saturable absorption phenomena. Therefore they do not provide an unambiguous demonstration of 'slow light'. Indeed a limiting condition on the spectral bandwidth is not generally satisfied, such that the requirements for burning a narrow spectral hole in the homogeneously broadened absorption line are not met. Some definitive tests of 'slow light' phenomena are suggested, derived from analysis of phase shift and pulse delay for a saturable absorber

Non-adiabatic quantum pumping by a randomly moving quantum dot  

E-Print Network [OSTI]

We look at random time dependent fluctuations of the electrical charge in an open 1D quantum system represented by a quantum dot experiencing random lateral motion. In essentially non-adiabatic settings we study both diffusive and ballistic (Levy) regimes of the barrier motion. Here the electric current as well as the net pumped electric charge experience random fluctuations over the static background. We show that in the large-time limit $t \\to \\infty$ the wavefunction is naturally separated into the Berry-phase component (resulting from the singular part of the wave amplitude in the co-moving frame) and the non-adiabatic correction (arising from fast oscillating, slow decaying tails of the same amplitude). In the special limit of a delta-correlated continuous Gaussian random walk we obtain closed analytical expressions for the ensemble averaged amplitude in the co-moving frame and demonstrate that the main contribution to the average wavefunction and probability current comes from the Berry-phase component which leads to the saturation of the fluctuations of the electric current and the pumped charge. We also derive the exact expressions for the average propagator (in the co-moving basis representation) for both types of motion.

SITE-SCALE SATURATED ZONE TRANSPORT  

SciTech Connect (OSTI)

This work provides a site-scale transport model for calculating radionuclide transport in the saturated zone (SZ) at Yucca Mountain, for use in the abstractions model in support of ''Total System Performance Assessment for License Application'' (TSPA-LA). The purpose of this model report is to provide documentation for the components of the site-scale SZ transport model in accordance with administrative procedure AP-SIII.10Q, Models. The initial documentation of this model report was conducted under the ''Technical Work Plan For: Saturated Zone Flow and Transport Modeling and Testing'' (BSC 2003 [DIRS 163965]). The model report has been revised in accordance with the ''Technical Work Plan For: Natural System--Saturated Zone Analysis and Model Report Integration'', Section 2.1.1.4 (BSC 2004 [DIRS 171421]) to incorporate Regulatory Integration Team comments. All activities listed in the technical work plan that are appropriate to the transport model are documented in this report and are described in Section 2.1.1.4 (BSC 2004 [DIRS 171421]). This report documents: (1) the advection-dispersion transport model including matrix diffusion (Sections 6.3 and 6.4); (2) a description and validation of the transport model (Sections 6.3 and 7); (3) the numerical methods for simulating radionuclide transport (Section 6.4); (4) the parameters (sorption coefficient, Kd ) and their uncertainty distributions used for modeling radionuclide sorption (Appendices A and C); (5) the parameters used for modeling colloid-facilitated radionuclide transport (Table 4-1, Section 6.4.2.6, and Appendix B); and (6) alternative conceptual models and their dispositions (Section 6.6). The intended use of this model is to simulate transport in saturated fractured porous rock (double porosity) and alluvium. The particle-tracking method of simulating radionuclide transport is incorporated in the finite-volume heat and mass transfer numerical analysis (FEHM) computer code, (FEHM V2.20, STN: 10086-2.20-00) (LANL 2003 [DIRS 161725]) and is described in Section 6.4 of this report. FEHM is a three-dimensional (3-D), finite-volume, finite-element, heat and mass flow-and-transport code. This report documents the features and capabilities of the site-scale transport model for calculating radionuclide transport in the SZ at Yucca Mountain in support of the TSPA-LA. Correlative flow-model calculations using FEHM are carried out and documented in the model report ''Saturated Zone Site-Scale Flow Model'' (BSC 2004 [DIRS 170037]). The velocity fields are calculated by the flow model independent of the transport processes and supplied as a part of the output package from the flow model, which is then used as inputs to the transport model. Several SZ analysis model reports provide information and data needed as feed-ins for this report, and this report in turn provides technical product outputs that feed into other SZ reports. The details of inputs to the site-scale transport model are provided in Section 4.

Vertical Variability in Saturated Zone Hydrochemistry Near Yucca Mountain, Nevada  

SciTech Connect (OSTI)

The differences in the saturated zone hydrochemistry with depth at borehole NC-EWDP-22PC reflect the addition of recharge along Fortymile Wash. The differences in water chemistry with depth at borehole NC-EWDP-19PB appear to indicate that other processes are involved. Water from the lower part of NC-EWDP-19PB possesses chemical characteristics that clearly indicate that it has undergone cation exchange that resulted in the removal of calcium and magnesium and the addition of sodium. This water is very similar to water from the Western Yucca Mountain facies that has previously been thought to flow west of NC-EWDP-19PB. Water from the lower zone in NC-EWDP-19PB also could represent water from the Eastern Yucca Mountain facies that has moved through clay-bearing or zeolitized aquifer material resulting in the altered chemistry. Water chemistry from the upper part of the saturated zone at NC-EWDP-19PB, both zones at NC-EWDP-22PC, and wells in the Fortymile Wash facies appears to be the result of recharge through the alluvium south of Yucca Mountain and within the Fortymile Wash channel.

Spectral Emission of Moving Atom  

E-Print Network [OSTI]

A renewed analysis of the H.E. Ives and G.R. Stilwell's experiment on moving hydrogen canal rays (J. Opt. Soc. Am., 1938, v.28, 215) concludes that the spectral emission of a moving atom exhibits always a redshift which informs not the direction of the atom's motion. The conclusion is also evident from a simple energy relation: atomic spectral radiation is emitted as an orbiting electron consumes a portion of its internal energy on transiting to a lower-energy state which however has in a moving atom an additional energy gain; this results in a redshift in the emission frequency. Based on auxiliary experimental information and a scheme for de Broglie particle formation, we give a vigorous elucidation of the mechanism for deceleration radiation of atomic electron; the corresponding prediction of the redshift is in complete agreement with the Ives and Stilwell's experimental formula.

Transmission Lines Emulating Moving Media  

E-Print Network [OSTI]

In this paper, we show how the electromagnetic phenomena in moving magnetodielectric media can be emulated using artificial composite structures at rest. In particular, we introduce nonreciprocal periodically loaded transmission lines which support waves obeying the same rules as plane electromagnetic waves in moving media. Because the actual physical structure is at rest, in these transmission lines there are no fundamental limitations on the velocity values, which may take values larger than the speed of light or even complex values (considering complex amplitudes in the time-harmonic regime). An example circuit of a unit cell of a "moving" transmission line is presented and analyzed both numerically and experimentally. The special case of composite right/left handed host line is also studied numerically. Besides the fundamental interest, the study is relevant for potential applications in realizing engineered materials for various transformations of electromagnetic fields.

Matters on a moving brane  

E-Print Network [OSTI]

A novel generalisation of the Dirac-Born-Infeld string scenario is described. It is shown that matter residing on the moving brane is dark and has the so-called disformal coupling to gravity. This gives rise to cosmologies where dark matter stems from the oscillations of the open strings along the brane and the transverse oscillations result in dark energy. Furthermore, due to a new screening mechanism that conceals the fifth force from local experiments, one may even entertain the possibility that the visible sector is also moving along the extra dimensions.

Moving observers, nonorthogonal boundaries, and quasilocal energy  

Science Journals Connector (OSTI)

The popular Hamilton-Jacobi method first proposed by Brown and York for defining quasilocal quantities such as energy for spatially bound regions assumes that the timelike boundary is orthogonal to the foliation of the spacetime. Such a restriction is undesirable for both theoretical and computational reasons. We remove the orthogonality assumption and show that it is more natural to focus on the foliation of the timelike boundary rather than the foliation of the entire four dimensional bound region. Reference spacetimes which define additional terms in the action are discussed in detail. To demonstrate this new formulation, we calculate the quasilocal energies seen by observers who are moving with respect to a Schwarzschild black hole.

Saturated Zone In-Situ Testing  

SciTech Connect (OSTI)

The purpose of this scientific analysis is to document the results and interpretations of field experiments that have been conducted to test and validate conceptual flow and radionuclide transport models in the saturated zone (SZ) near Yucca Mountain. The test interpretations provide estimates of flow and transport parameters that are used in the development of parameter distributions for Total System Performance Assessment (TSPA) calculations. These parameter distributions are documented in the revisions to the SZ flow model report (BSC 2003 [ 162649]), the SZ transport model report (BSC 2003 [ 162419]), the SZ colloid transport report (BSC 2003 [162729]), and the SZ transport model abstraction report (BSC 2003 [1648701]). Specifically, this scientific analysis report provides the following information that contributes to the assessment of the capability of the SZ to serve as a barrier for waste isolation for the Yucca Mountain repository system: (1) The bases for selection of conceptual flow and transport models in the saturated volcanics and the saturated alluvium located near Yucca Mountain. (2) Results and interpretations of hydraulic and tracer tests conducted in saturated fractured volcanics at the C-wells complex near Yucca Mountain. The test interpretations include estimates of hydraulic conductivities, anisotropy in hydraulic conductivity, storativities, total porosities, effective porosities, longitudinal dispersivities, matrix diffusion mass transfer coefficients, matrix diffusion coefficients, fracture apertures, and colloid transport parameters. (3) Results and interpretations of hydraulic and tracer tests conducted in saturated alluvium at the Alluvium Testing Complex (ATC), which is located at the southwestern corner of the Nevada Test Site (NTS). The test interpretations include estimates of hydraulic conductivities, storativities, total porosities, effective porosities, longitudinal dispersivities, matrix diffusion mass transfer coefficients, and colloid transport parameters. (4) Comparisons of sorption parameter estimates for a reactive solute tracer (lithium ion) derived from both the C-wells field tracer tests and laboratory tests using C-wells core samples. (5) Sorption parameter estimates for lithium ion derived from laboratory tests using alluvium samples from NC-EWDP-19D1 (one of the wells at the ATC) so that a comparison of laboratory- and field-derived sorption parameters can be made in saturated alluvium if cross-hole tracer tests are conducted at the ATC.

Numerical study of the validity of the Boussinesq approximation for a fluid-saturated porous medium  

SciTech Connect (OSTI)

The validity of the Boussinesq approximation is investigated for natural convection in a fluid-saturated porous medium. A perturbation method is utilized to assess the relative importance of individual terms in the differential equations which describe the natural convection process. Specific limits to the validity of the Boussinesq approximation are identified for water and air. For water, it is shown that the restrictions imposed by the classical Boussinesq appoximation can be relaxed by allowing for the variation of thermophysical properties with temperature while still retaining the incompressible form of the continuity relation. Results of the analysis are verified through numerical calculations performed for steady natural convvection in a planar, water-saturated porous region, of unity aspect ratio, subjected to a tempertaure difference imposed between the vertical side walls.

Saturation of elliptic flow and shear viscosity  

E-Print Network [OSTI]

Effect of shear viscosity on elliptic flow is studied in causal dissipative hydrodynamics in 2+1 dimensions. Elliptic flow is reduced in viscous dynamics. Causal evolution of minimally viscous fluid ($\\eta/s$=0.08), can explain the PHENIX data on elliptic flow in 16-23% Au+Au collisions up to $p_T\\approx$3.6 GeV. In contrast, ideal hydrodynamics, can explain the same data only up to $p_T\\approx$1.5 GeV. $p_T$ spectra of identified particles are also better explained in minimally viscous fluid than in ideal dynamics. However, saturation of elliptic flow at large $p_T$ is not reproduced.

A Multivariate Moving Average Control Chart for Photovoltaic Processes  

E-Print Network [OSTI]

Abstract—For the electrical metrics that describe photovoltaic cell performance are inherently multivariate in nature, use of a univariate, or one variable, statistical process control chart can have important limitations. Development of a comprehensive process control strategy is known to be significantly beneficial to reducing process variability that ultimately drives up the manufacturing cost photovoltaic cells. The multivariate moving average or MMA chart, is applied to the electrical metrics of photovoltaic cells to illustrate the improved sensitivity on process variability this method of control charting offers. The result show the ability of the MMA chart to expand to as any variables as needed, suggests an application with multiple photovoltaic electrical metrics being used in concert to determine the processes state of control.

SATURATED ZONE FLOW AND TRANSPORT MODEL ABSTRACTION  

SciTech Connect (OSTI)

The purpose of the saturated zone (SZ) flow and transport model abstraction task is to provide radionuclide-transport simulation results for use in the total system performance assessment (TSPA) for license application (LA) calculations. This task includes assessment of uncertainty in parameters that pertain to both groundwater flow and radionuclide transport in the models used for this purpose. This model report documents the following: (1) The SZ transport abstraction model, which consists of a set of radionuclide breakthrough curves at the accessible environment for use in the TSPA-LA simulations of radionuclide releases into the biosphere. These radionuclide breakthrough curves contain information on radionuclide-transport times through the SZ. (2) The SZ one-dimensional (I-D) transport model, which is incorporated in the TSPA-LA model to simulate the transport, decay, and ingrowth of radionuclide decay chains in the SZ. (3) The analysis of uncertainty in groundwater-flow and radionuclide-transport input parameters for the SZ transport abstraction model and the SZ 1-D transport model. (4) The analysis of the background concentration of alpha-emitting species in the groundwater of the SZ.

Calculations of composition boundaries of saturated phases  

SciTech Connect (OSTI)

A program for the HP-41CV calculator is presented for calculating the equilibrium composition boundaries of pairs of saturating solids, liquids, or a combination of a solid and liquid. The activity coefficients must be represented in the form ln ..gamma../sub 1/ = (b/sub h//T - b/sub s/)x/sub 2//sup 2/ + (c/sub h//T - c/sub x/)x/sub 2//sup 3/ where h refers to an enthalpy contribution and s refers to an excess entropy contribution. For solid-liquid equilibria, enthalpies and entropies of fusion are required. For all equilibria, provision is made for use of hypothetical standard states such as the Henry's Law standard states. For example, in treating solid solutions of molybdenum in face-centered cubic metals such as Ni, Rh, or Pt, it is sometimes convenient to use a hypothetical fcc standard state of Mo which represents the limiting Henry's Law behavior of Mo in the fcc metal and has much different properties than a real fcc molybdenum solid.

Methane hydrate formation and dissociation in a partially saturated sand  

SciTech Connect (OSTI)

To predict the behavior of hydrate-bearing sediments and the economic extractability of natural gas from reservoirs containing gas hydrates, we need reservoir simulators that properly represent the processes that occur, as well as accurate parameters. Several codes are available that represent some or all of the expected processes, and values for some parameters are available. Where values are unavailable, modelers have used estimation techniques to help with their predictions. Although some of these techniques are well respected, measurements are needed in many cases to verify the parameters. We have performed a series of experiments in a partially water saturated silica sand sample. The series included methane hydrate formation, and dissociation by both thermal stimulation and depressurization. The sample was 7.6 cm in diameter and 25 cm in length. In addition to measuring the system pressure and temperatures at four locations in the sample, we measured local density within the sample using x-ray computed tomography. Our goals in performing the experiment were to gather information for estimating thermal properties of the medium and to examine nonequilibrium processes.

Methane Hydrate Formation and Dissocation in a Partially Saturated Sand--Measurements and Observations  

SciTech Connect (OSTI)

We performed a sequence of tests on a partially water-saturated sand sample contained in an x-ray transparent aluminum pressure vessel that is conducive to x-ray computed tomography (CT) observation. These tests were performed to gather data for estimation of thermal properties of the sand/water/gas system and the sand/hydrate/water/gas systems, as well as data to evaluate the kinetic nature of hydrate dissociation. The tests included mild thermal perturbations for the estimation of the thermal properties of the sand/water/gas system, hydrate formation, thermal perturbations with hydrate in the stability zone, hydrate dissociation through thermal stimulation, additional hydrate formation, and hydrate dissociation through depressurization with thermal stimulation. Density changes throughout the sample were observed as a result of hydrate formation and dissociation, and these processes induced capillary pressure changes that altered local water saturation.

On the propagation of a coupled saturation and pressure front  

SciTech Connect (OSTI)

Using an asymptotic technique, valid for a medium with smoothly varying heterogeneity, I derive an expression for the velocity of a propagating, coupled saturation and pressure front. Due to the nonlinearity of the governing equations, the velocity of the propagating front depends upon the magnitude of the saturation and pressure changes across the front in addition to the properties of the medium. Thus, the expression must be evaluated in conjunction with numerical reservoir simulation. The propagation of the two-phase front is governed by the background saturation distribution, the saturation-dependent component of the fluid mobility, the porosity, the permeability, the capillary pressure function, the medium compressibility, and the ratio of the slopes of the relative permeability curves. Numerical simulation of water injection into a porous layer saturated with a nonaqueous phase liquid indicates that two modes of propagation are important. The fastest mode of propagation is a pressure-dominated disturbance that travels through the saturated layer. This is followed, much later, by a coupled mode with a large saturation change. These two modes are also observed in a simulation using a heterogeneous porous layer. A comparison between the propagation times estimated from the results of the numerical simulation and predictions from the asymptotic expression indicates overall agreement.

Dynamic core length in saturated core fault current limiters  

Science Journals Connector (OSTI)

A saturated core fault current limiter (SCFCL) is a non-linear core-reactor where the core is saturated by an external superconducting DC bias source to achieve a low core permeability at nominal AC currents. Fault current levels in the AC coils de-saturate the core and transform it to a higher permeability state, hence limiting the fault current. In this work we describe the transition between saturated and de-saturated states in three SCFCL configurations. The 'effective core length', Leff, of the SCFCL, defined as the length of the de-saturated AC core limb, is introduced for exploring this transition as a function of the current, I, in the AC coil. Practically, Leff allows one to see the SCFCL as an inductor with a variable core length, allowing calculations of the impedance of the SCFCL over the whole range of operating currents. The Leff(I) curve is further used to calculate the dynamics of the demagnetization factor in a SCFCL. We show that the strong change in the magnetic induction of a SCFCL at high current is the result of both increasing the effective core length and decreasing the demagnetization factor. The method and results presented here serve as an important tool for comparing between various SCFCL concepts not only by comparing their impedance values at the extreme fault and nominal current conditions but also by providing an insight into the full de-saturation process.

Prediction of core saturation instability at an HVDC converter  

SciTech Connect (OSTI)

Core saturation instability has occurred on several HVDC schemes resulting from interactions between second harmonic and dc quantities (voltages and currents) on the ac side of the converter and fundamental frequency quantities on the dc side of the converter. The instability can be reinforced by unbalanced saturation of the converter transformers. The paper presents an analytical method which can be used to quickly screen ac and dc system operating conditions to predict where core saturation instability is likely to occur. Analytical results have been confirmed using the digital transients simulation program PSCAD/EMTDC.

Dick tripped as he was getting off of the escalator. The incident made him consider the day-to-day hazards we take for granted. With this in mind, Dick made an effort to look around to find safety information about using elevators, escalators and moving walkways. Dick came across some useful safety information provided by the Otis Elevator Company. The web site below provides links to two good one-page reminders for safety on elevators, escalators, and moving walkways. http://www.otis.com/site/us/Pages/SafetyforAll.aspx Dick also found more interactive presentations on the same material, see website below.

Method of determining interwell oil field fluid saturation distribution  

DOE Patents [OSTI]

A method of determining the oil and brine saturation distribution in an oil field by taking electrical current and potential measurements among a plurality of open-hole wells geometrically distributed throughout the oil field. Poisson's equation is utilized to develop fluid saturation distributions from the electrical current and potential measurement. Both signal generating equipment and chemical means are used to develop current flow among the several open-hole wells.

Nonlinear Thoery of Ultrasonic Wave Amplification and Current Saturation in Piezoelectric Semiconductors  

Science Journals Connector (OSTI)

A nonlinear theory based on numerical calculation is developed for the amplification of ultrasonic waves in piezoelectric semiconductors. The theory is one-dimensional and applies to semiconductors at room temperature in which the mean free path of the carriers is small compared with the acoustic wavelength. To provide a physical understanding of the problem, the following quantities are investigated in detail: (1) the carrier and the piezoelectric potential distributions and their relative phases, (2) the harmonic content of the elastic wave caused by the electronic interaction, (3) the acoustoelectric current and the nonuniform distribution of the dc electric field in the crystal, and (4) the effect of nonelectronic loss. As the intensity of the elastic wave increases, the drift velocity of the carriers starts from the Ohmic velocity and gradually decreases to the speed of sound. Similarly, the acoustic gain expressed in nepers per unit distance starts from the small-signal value and decreases slowly toward zero. The results obtained for the current and gain saturations described above in various conditions of amplification are presented in universal curves. We find that the current saturation occurs because the carriers are trapped in the troughs of the large piezoelectric potential excited by the elastic wave and are forced to move along with the wave at the speed of sound. We also show that this concept of the current saturation is entirely consistent with the calculation of the acoustoelectric current. Later, in a study of the acoustoelectric current and the Weinreich relation by means of simple power relations, we calculate the efficiency for the conversion of electronic energy to elastic energy. Among other findings we show that in a nonlinear theory, the Weinreich relation can be written for each harmonic independently. Finally, the theory is applied to various phenomena of acoustoelectric origin. Several simulation calculations are made for the propagation of high-field domains, and they verify the phenomena of "pinned" domains and the associated damped current oscillations observed experimentally in photoconductive CdS. Good agreement is also obtained between the present theory and the existing measurements of gain saturation.

Analytical model for flux saturation in sediment transport  

E-Print Network [OSTI]

The transport of sediment by a fluid along the surface is responsible for dune formation, dust entrainment and for a rich diversity of patterns on the bottom of oceans, rivers, and planetary surfaces. Most previous models of sediment transport have focused on the equilibrium (or saturated) particle flux. However, the morphodynamics of sediment landscapes emerging due to surface transport of sediment is controlled by situations out-of-equilibrium. In particular, it is controlled by the saturation length characterizing the distance it takes for the particle flux to reach a new equilibrium after a change in flow conditions. The saturation of mass density of particles entrained into transport and the relaxation of particle and fluid velocities constitute the main relevant relaxation mechanisms leading to saturation of the sediment flux. Here we present a theoretical model for sediment transport which, for the first time, accounts for both these relaxation mechanisms and for the different types of sediment entrainment prevailing under different environmental conditions. Our analytical treatment allows us to derive a closed expression for the saturation length of sediment flux, which is general and can thus be applied under different physical conditions.

Moving mass trim control system design  

SciTech Connect (OSTI)

This paper describes the design of a moving mass trim control system for maneuvering axisymmetric reentry vehicles. The moving mass trim controller is composed of three equal masses that are independently positioned in order to deliver a desired center of mass position. For a slowly spinning reentry vehicle, the mass offset creates a trim angle-of-attack to generate modest flight path corrections. The control system must maintain the desired position of each mass in the face of large disturbances. A novel algorithm for determining the desired mass positions is developed in conjunction with a preliminary controller design. The controller design is based on classical frequency domain techniques where a bound on the disturbance magnitude is used to formulate the disturbance rejection problem. Simulation results for the controller are presented for a typical reentry vehicle.

Roughening Transition in a Moving Contact Line  

E-Print Network [OSTI]

The dynamics of the deformations of a moving contact line on a disordered substrate is formulated, taking into account both local and hydrodynamic dissipation mechanisms. It is shown that both the coating transition in contact lines receding at relatively high velocities, and the pinning transition for slowly moving contact lines, can be understood in a unified framework as roughening transitions in the contact line. We propose a phase diagram for the system in which the phase boundaries corresponding to the coating transition and the pinning transition meet at a junction point, and suggest that for sufficiently strong disorder a receding contact line will leave a Landau--Levich film immediately after depinning. This effect may be relevant to a recent experimental observation in a liquid Helium contact line on a Cesium substrate [C. Guthmann, R. Gombrowicz, V. Repain, and E. Rolley, Phys. Rev. Lett. {\\bf 80}, 2865 (1998)].

Repelling magnetic forces are produced by the interaction of a flux-concentrated magnetic field (produced by permanent magnets or electromagnets) with an inductively loaded closed electric circuit. When one such element moves with respect to the other, a current is induced in the circuit. This current then interacts back on the field to produce a repelling force. These repelling magnetic forces are applied to magnetically levitate a moving object such as a train car. The power required to levitate a train of such cars is drawn from the motional energy of the train itself, and typically represents only a percent or two of the several megawatts of power required to overcome aerodynamic drag at high speeds. 7 figs.

Determining the Porosity and Saturated Hydraulic Conductivity of Binary Mixtures  

SciTech Connect (OSTI)

Gravels and coarse sands make up significant portions of some environmentally important sediments, while the hydraulic properties of the sediments are typically obtained in the laboratory using only the fine fraction (e.g., <2 mm or 4.75 mm). Researchers have found that the content of gravel has significant impacts on the hydraulic properties of the bulk soils. Laboratory experiments were conducted to measure the porosity and the saturated hydraulic conductivity of binary mixtures with different fractions of coarse and fine components. We proposed a mixing-coefficient model to estimate the porosity and a power-averaging method to determine the effective particle diameter and further to predict the saturated hydraulic conductivity of binary mixtures. The proposed methods could well estimate the porosity and saturated hydraulic conductivity of the binary mixtures for the full range of gravel contents and was successfully applied to two data sets in the literature.

Compared to last year when only 36 Bcf or 1.2 Bcf per day were added to stocks in April, this year the industry appears to be taking advantage of the reduction in demand that typically occurs in April, the first shoulder month of the year, and the recent price declines. After beginning the week down, spot prices at the Henry Hub trended down most days last week to end trading on Friday at $4.49 per MMBtu-the lowest price since early November. On the NYMEX futures market, the near-month (June) contract also moved down most days and ended last week at $4.490-down $0.377 from the previous Friday. Some-early summer high temperatures last week in the Northeast and winter-like weather in the Rockies (See Temperature Map) (See Deviation from Normal Temperatures Map) appear to have had little impact on the natural gas markets as prices declined most days at most major locations.

Moving Memristor and Neuristor Moving Memristor and Neuristor Research Forward Moving Memristor and Neuristor Research Forward Print Thursday, 21 March 2013 10:01 HP Labs researchers have tackled a decades-old mystery relying on powerful ALS microscopy techniques to better understand the fourth basic circuit element: the memristor. The memristor (short for "memory resistor") joins the other passive elements-the capacitor, the resistor, and the inductor-to create a device with the ability to "remember" changes even when it loses power. Commercial development based on memristors offers the promise of computing systems with highly advanced energy efficiency and memory retention. Memristor-based memory could be a strong competitor for current flash memory. "The basic idea is that if you run current through a device you'll not only measure a certain resistance, but that same current-if strong enough-will also be transforming that resistance," says John Paul Strachan (at left), Research Scientist at HP Labs whose team develops new electronic and optical devices and applications. "This has clear cut applications in memory - you're able to store that state and then read it out and rewrite it."

Discrimination of porosity and fluid saturation using seismic velocity analysis  

DOE Patents [OSTI]

The method of the invention is employed for determining the state of saturation in a subterranean formation using only seismic velocity measurements (e.g., shear and compressional wave velocity data). Seismic velocity data collected from a region of the formation of like solid material properties can provide relatively accurate partial saturation data derived from a well-defined triangle plotted in a (.rho./.mu., .lambda./.mu.)-plane. When the seismic velocity data are collected over a large region of a formation having both like and unlike materials, the method first distinguishes the like materials by initially plotting the seismic velocity data in a (.rho./.lambda., .mu./.lambda.)-plane to determine regions of the formation having like solid material properties and porosity.

Strong subadditivity inequality of quantum entropy, proved by Lieb and Ruskai, is a powerful tool in quantum information theory. The fact that the strong subadditivity inequality saturated only by a so-called Markov states is obtained in the recent literature [P. Hayden et al., Commun. Math. Phys. 246, 359 (2004).]. In this report, we will give a characterization to an another equivalent version of strong subadditivity inequality. The possible applications are discussed.

Supercritical Hadley circulation within a layer of fluid saturated porous medium: Bifurcation to traveling wave  

SciTech Connect (OSTI)

Hadley circulation induced by horizontal and vertical temperature gradients imposed on a fluid saturated porous medium layer is simulated numerically. The flow is assumed to be longitudinal, that is the secondary flow is composed of cells with axes transverse to the direction of the Hadley circulation. Critical (bifurcation) states predicted theoretically via linear stability analysis are verified by the numerical results giving confidence on the accuracy of the method. Several values of horizontal Rayleigh number, Ra{sub h}, and vertical Rayleigh number, Ra{sub v}, are studied. Results indicate that beyond a threshold horizontal Rayleigh number value the flow and temperature fields evolve from subcritical Hadley circulation to a supercritical time periodic flow. The secondary flow emerges in the form of a traveling wave aligned with the main (Hadley) flow direction. This traveling wave is characterized, at supercritical low vertical Rayleigh numbers, by the continuous drifting of two horizontal layers of flow cells that move in opposite directions. As the vertical Rayleigh number increases, the traveling wave becomes characterized by a unique layer of cells drifting in the direction opposite to the applied horizontal temperature gradient. Numerical animation unravels the main features of the transport process. This simplified model is of fundamental and practical importance, for instance, to the study of geothermal activities, underground transport of pollutants, paper processing, crystal growth, building insulation, and gas reservoirs.

Rapidly Moving Divertor Plates In A Tokamak  

SciTech Connect (OSTI)

It may be possible to replace conventional actively cooled tokamak divertor plates with a set of rapidly moving, passively cooled divertor plates on rails. These plates would absorb the plasma heat flux with their thermal inertia for ~10-30 sec, and would then be removed from the vessel for processing. When outside the tokamak, these plates could be cooled, cleaned, recoated, inspected, and then returned to the vessel in an automated loop. This scheme could provide nearoptimal divertor surfaces at all times, and avoid the need to stop machine operation for repair of damaged or eroded plates. We describe various possible divertor plate designs and access geometries, and discuss an initial design for a movable and removable divertor module for NSTX-U.

CIRCULATING MOVING BED COMBUSTION PROOF OF CONCEPT  

SciTech Connect (OSTI)

Circulating Moving Bed (CMB) combustion technology has its roots in traditional circulating fluidized bed technology and involves a novel method of solid fuel combustion and heat transfer. CMB technology represents a step change in improved performance and cost relative to conventional PC and FBC boilers. The CMB heat exchanger preheats the energy cycle working fluid, steam or air, to the high temperature levels required in systems for advanced power generation. Unique features of the CMB are the reduction of the heat transfer surfaces by about 60% as a result of the enhanced heat transfer rates, flexibility of operation, and about 30% lower cost over existing technology. The CMB Phase I project ran from July 2001 through March 2003. Its objective was to continue development of the CMB technology with a series of proof of concept tests. The tests were conducted at a scale that provided design data for scale up to a demonstration plant. These objectives were met by conducting a series of experiments in ALSTOM Power’s Multi-use Test Facility (MTF). The MTF was modified to operate under CMB conditions of commercial interest. The objective of the tests were to evaluate gas-to-solids heat transfer in the upper furnace, assess agglomeration in the high temperature CMB bubbling bed, and evaluate solids-to-tube heat transfer in the moving bed heat exchanger. The Phase I program results showed that there are still some significant technical uncertainties that needed to be resolved before the technology can be confidently scaled up for a successful demonstration plant design. Work remained in three primary areas: • scale up of gas to solid heat transfer • high temperature finned surface design • the overall requirements of mechanical and process design. The CMB Phase II workscope built upon the results of Phase I and specifically addressed the remaining technical uncertainties. It included a scaled MTF heat transfer test to provide the necessary data to scale up gas-to-solids heat transfer. A stress test rig was built and tested to provide validation data for a stress model needed to support high temperature finned surface design. Additional cold flow model tests and MTF tests were conducted to address mechanical and process design issues. This information was then used to design and cost a commercial CMB design concept. Finally, the MBHE was reconfigured into a slice arrangement and tested for an extended duration at a commercial CFB plant.

Casimir Friction Force for Moving Harmonic Oscillators  

E-Print Network [OSTI]

Casimir friction is analyzed for a pair of dielectric particles in relative motion. We first adopt a microscopic model for harmonically oscillating particles at finite temperature T moving non-relativistically with constant velocity. We use a statistical-mechanical description where time-dependent correlations are involved. This description is physical and direct, and, in spite of its simplicity, is able to elucidate the essentials of the problem. This treatment elaborates upon, and extends, an earlier theory of ours back in 1992. The energy change Delta E turns out to be finite in general, corresponding to a finite friction force. In the limit of zero temperature the formalism yields, however, Delta E ->0, this being due to our assumption about constant velocity, meaning slowly varying coupling. For couplings varying more rapidly, there will also be a finite friction force at T=0. As second part of our work, we consider the friction problem using time-dependent perturbation theory. The dissipation, basically a second order effect, is obtainable with the use of first order theory, the reason being the absence of cross terms due to uncorrelated phases of eigenstates. The third part of the present paper is to demonstrate explicitly the equivalence of our results with those recently obtained by Barton (2010); this being not a trivial task since the formal results are seemingly quite different from each other.

Hydrogen atom moving across a magnetic field  

Science Journals Connector (OSTI)

A hydrogen atom moving across a magnetic field is considered in a wide region of magnitudes of magnetic field and atom momentum. We solve the Schrödinger equation of the system numerically using an imaginary time method and find wave functions of the lowest states of atom. We calculate the energy and the mean electron-nucleus separation as a function of atom momentum and magnetic field. All the results obtained could be summarized as a phase diagram on the “atom-momentum – magnetic-field” plane. There are transformations of wave-function structure at critical values of atom momentum and magnetic field that result in a specific behavior of dependencies of energy and mean interparticle separation on the atom momentum P. We discuss a transition from the Zeeman regime to the high magnetic field regime. A qualitative analysis of the complicated behavior of wave functions vs P based on the effective potential examination is given. We analyze a sharp transition at the critical momentum from a Coulomb-type state polarized due to atom motion to a strongly decentered (Landau-type) state at low magnetic fields. A crossover occurring at intermediate magnetic fields is also studied.

Spin-glass model of QCD near saturation  

E-Print Network [OSTI]

We establish a connection between the cascading of gluon momenta modeled with the diffusive approximation of the Balitsky-Fadin-Kuraev-Lipatov kernel and the thermodynamics of directed polymers on a tree with disorder. Using known results on the low-temperature spin-glass phase of this statistical-mechanic problem we describe the dynamical phase space of gluon transverse momenta near saturation including its fluctuation pattern. It exhibits a nontrivial clustering structure, analoguous to ``hot spots'', whose distributions are derived and possess universal features in common with other spin-glass systems.

Calcite growth rates as a function of aqueous calcium-to-carbonate ratio, saturation index and strontium concentration  

SciTech Connect (OSTI)

Using in situ atomic force microscopy, the growth rates of the obtuse and acute step orientations on the calcite surface were measured at two saturation indices as a function of the aqueous calcium-to-carbonate ratio and aqueous strontium concentration. The amount of strontium required to inhibit growth was found to correlate with the aqueous calcium concentration, but did not correlate with carbonate. This suggests that strontium inhibits attachment of calcium ions to the reactive sites on the calcite surface. Strontium/calcium cation exchange selectivity coefficients for those sites, Kex, of 1.09 0.09 and 1.44 0.19 are estimated for the obtuse and acute step orientations, respectively. The implication of this finding is that to avoid poisoning calcite growth, the concentration of calcium should be higher than the quotient of the strontium concentration and Kex, regardless of saturation state. Additionally, analytical models of nucleation and propagation of steps are expanded from previous work to capture growth rates of these steps at multiple saturation indices and the effect of strontium. This work will have broader implications for naturally occurring or engineered calcite growth, such as to sequester subsurface strontium contamination.

Laboratory analysis of fluid flow and solute transport through a variably saturated fracture embedded in porous tuff  

SciTech Connect (OSTI)

Laboratory techniques are developed that allow concurrent measurement of unsaturated matrix hydraulic conductivity and fracture transmissivity of fractured rock blocks. Two Apache Leap tuff blocks with natural fractures were removed from near Superior, Arizona, shaped into rectangular prisms, and instrumented in the laboratory. Porous ceramic plates provided solution to block tops at regulated pressures. Infiltration tests were performed on both test blocks. Steady flow testing of the saturated first block provided estimates of matrix hydraulic conductivity and fracture transmissivity. Fifteen centimeters of suction applied to the second block top showed that fracture flow was minimal and matrix hydraulic conductivity was an order of magnitude less than the first block saturated matrix conductivity. Coated-wire ion-selective electrodes monitored aqueous chlorided breakthrough concentrations. Minute samples of tracer solution were collected with filter paper. The techniques worked well for studying transport behavior at near-saturated flow conditions and also appear to be promising for unsaturated conditions. Breakthrough curves in the fracture and matrix, and a concentration map of chloride concentrations within the fracture, suggest preferential flows paths in the fracture and substantial diffusion into the matrix. Average travel velocity, dispersion coefficient and longitudinal dispersivity in the fracture are obtained. 67 refs., 54 figs., 23 tabs.

Compacted Na-bentonite clay barriers, widely used in theisolation of solid-waste landfills and other contaminated sites, havebeen proposed for a similar use in the disposal of high-level radioactivewaste. Molecular diffusion through the pore space in these barriers playsa key role in their performance, thus motivating recent measurements ofthe apparent diffusion coefficient tensor of water tracers in compacted,water-saturated Na-bentonites. In the present study, we introduce aconceptual model in which the pore space of water-saturated bentonite isdivided into 'macropore' and 'interlayer nanopore' compartments. Withthis model we determine quantitatively the relative contributions ofpore-network geometry (expressed as a geometric factor) and of thediffusive behavior of water molecules near montmorillonite basal surfaces(expressed as a contristivity factor) to the apparent diffusioncoefficient tensor. Our model predicts, in agreement with experiment,that the mean principal value of the apparent diffusion coefficienttensor follows a single relationship when plotted against the partialmontmorillonite dry density (mass of montmorillonite per combined volumeof montmorillonite and pore space). Using a single fitted parameter, themean principal geometric factor, our model successfully describes thisrelationship for a broad range of bentonite-water system, from dilute gelto highly-compacted bentonite with 80 percent of its pore water ininterlayer nanopores.

Yucca Mountain Area Saturated Zone Dissolved Organic Carbon Isotopic Data  

SciTech Connect (OSTI)

Groundwater samples in the Yucca Mountain area were collected for chemical and isotopic analyses and measurements of water temperature, pH, specific conductivity, and alkalinity were obtained at the well or spring at the time of sampling. For this project, groundwater samples were analyzed for major-ion chemistry, deuterium, oxygen-18, and carbon isotopes of dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC). The U.S. Geological Survey (USGS) performed all the fieldwork on this project including measurement of water chemistry field parameters and sample collection. The major ions dissolved in the groundwater, deuterium, oxygen-18, and carbon isotopes of dissolved inorganic carbon (DIC) were analyzed by the USGS. All preparation and processing of samples for DOC carbon isotopic analyses and geochemical modeling were performed by the Desert Research Institute (DRI). Analysis of the DOC carbon dioxide gas produced at DRI to obtain carbon-13 and carbon-14 values was conducted at the University of Arizona Accelerator Facility (a NSHE Yucca Mountain project QA qualified contract facility). The major-ion chemistry, deuterium, oxygen-18, and carbon isotopes of DIC were used in geochemical modeling (NETPATH) to determine groundwater sources, flow paths, mixing, and ages. The carbon isotopes of DOC were used to calculate groundwater ages that are independent of DIC model corrected carbon-14 ages. The DIC model corrected carbon-14 calculated ages were used to evaluate groundwater travel times for mixtures of water including water beneath Yucca Mountain. When possible, groundwater travel times were calculated for groundwater flow from beneath Yucca Mountain to down gradient sample sites. DOC carbon-14 groundwater ages were also calculated for groundwaters in the Yucca Mountain area. When possible, groundwater travel times were estimated for groundwater flow from beneath Yucca Mountain to down gradient groundwater sample sites using the DOC calculated groundwater ages. The DIC calculated groundwater ages were compared with DOC calculated groundwater ages and both of these ages were compared to travel times developed in ground-water flow and transport models. If nuclear waste is stored in Yucca Mountain, the saturated zone is the final barrier against the release of radionuclides to the environment. The most recent rendition of the TSPA takes little credit for the presence of the saturated zone and is a testament to the inadequate understanding of this important barrier. If radionuclides reach the saturated zone beneath Yucca Mountain, then there is a travel time before they would leave the Yucca Mountain area and flow down gradient to the Amargosa Valley area. Knowing how long it takes groundwater in the saturated zone to flow from beneath Yucca Mountain to down gradient areas is critical information for potential radionuclide transport. Radionuclide transport in groundwater may be the quickest pathway for radionuclides in the proposed Yucca Mountain repository to reach land surface by way of groundwater pumped in Amargosa Valley. An alternative approach to ground-water flow and transport models to determine the travel time of radionuclides from beneath Yucca Mountain to down gradient areas in the saturated zone is by carbon-14 dating of both inorganic and organic carbon dissolved in the groundwater. A standard method of determining ground-water ages is to measure the carbon-13 and carbon-14 of DIC in the groundwater and then correct the measured carbon-14 along a flow path for geochemical reactions that involve carbon containing phases. These geochemical reactions are constrained by carbon-13 and isotopic fractionations. Without correcting for geochemical reactions, the ground-water ages calculated from only the differences in carbon-14 measured along a flow path (assuming the decrease in carbon-14 is due strictly to radioactive decay) could be tens of thousands of years too old. The computer program NETPATH, developed by the USGS, is the best geochemical program for correcting carbon-14 activities for geochemical r

Quantum-chemical investigation of five-membered saturated heterocycles  

SciTech Connect (OSTI)

The objects of the authors' investigation were five-membered rings with ine heteroatom in the ring, viz., tetrahydrofuran, tetrahydrothiophene, pyrrolidine, and N-methylpyrrolidine, as well as several 1,2- and 1,3-diheterocyclopentanes, viz., 1,2-dioxolane, 1,2-pyrazolidine, 1,3-dioxolane, 1,3-dithiolane, N,N'-dimethyl-1,3-imidazolidine, and N-methyl-1.3-oxazolidine. It is shown that among the various semiempirical variations of the SCF MO LCAO approximation, the MNDO method correctly and most accurately reproduces the equilibrium geometry of molecules of saturated five-membered heterocycles. The MINDO/3 method produces smaller deviations of the first ionization potentials from the experimental values than do the MNDO and CNDO/2 methods. An analysis of the photoelectron spectra has been carried out by this method on the basis of the data from calculations.

BRAHMS RESULTS IN THE CONTEXT OF SATURATION AND QUANTUM EVOLUTION.  

SciTech Connect (OSTI)

We report BRAHMS results from RHIC d+Au and p+p collisions at {radical}S{sub NN} = 200GeV. A remarkable change in the nuclear modification factor R{sub dAu} is seen as the pseudorapidity of the detected charged hadrons changes from zero at mid-rapidity to 3.2 at the most forward angle studied during the 2003 run. For pseudorapidity {eta} > 1 the suppression of the R{sub cp} factor is more pronounced in the sample of central events in contrast to the behavior at mid-rapidity where the central events show higher enhancement compared to a semi-central sample. These results are consistent with a saturated Au wave function strongly affected by quantum evolution at higher values of rapidity.

Saturated Zone Plumes in Volcanic Rock: Implications for Yucca Mountain  

SciTech Connect (OSTI)

This paper presents a literature survey of the occurrences of radionuclide plumes in saturated, fractured rocks. Three sites, Idaho National laboratory, Hanford, and Oak Ridge are discussed in detail. Results of a modeling study are also presented showing that the length to width ratio of a plume starting within the repository footprint at the Yucca Mountain Project site, decreases from about 20:1 for the base case to about 4:1 for a higher value of transverse dispersivity, indicating enhanced lateral spreading of the plume. Due to the definition of regulatory requirements, this lateral spreading does not directly impact breakthrough curves at the 18 km compliance boundary, however it increases the potential that a plume will encounter reducing conditions, thus significantly retarding the transport of sorbing radionuclides.

Nuclear Saturation with In-Medium Meson Exchange Interactions

We show that the assumption of dropping meson masses together with conventional many-body effects, implemented in the relativistic Dirac-Brueckner formalism, explains nuclear saturation. We use a microscopic model for correlated 2{pi} exchange and include the standard many-body effects on the in-medium pion propagation, which initially increase the attractive nucleon-nucleon (NN ) potential with density. For the vector meson exchanges in both the {pi}{pi} and NN sector, we assume Brown-Rho scaling which{emdash}in concert with {open_quotes}chiral{close_quotes} {pi}{pi} contact interactions{emdash}reduces the attraction at higher densities. {copyright} {ital 1999} {ital The American Physical Society}

Unsaturated Zone and Saturated Zone Transport Properties (U0100)  

SciTech Connect (OSTI)

This Analysis/Model Report (AMR) summarizes transport properties for the lower unsaturated zone hydrogeologic units and the saturated zone at Yucca Mountain and provides a summary of data from the Busted Butte Unsaturated Zone Transport Test (UZTT). The purpose of this report is to summarize the sorption and transport knowledge relevant to flow and transport in the units below Yucca Mountain and to provide backup documentation for the sorption parameters decided upon for each rock type. Because of the complexity of processes such as sorption, and because of the lack of direct data for many conditions that may be relevant for Yucca Mountain, data from systems outside of Yucca Mountain are also included. The data reported in this AMR will be used in Total System Performance Assessment (TSPA) calculations and as general scientific support for various Process Model Reports (PMRs) requiring knowledge of the transport properties of different materials. This report provides, but is not limited to, sorption coefficients and other relevant thermodynamic and transport properties for the radioisotopes of concern, especially neptunium (Np), plutonium (Pu), Uranium (U), technetium (Tc), iodine (I), and selenium (Se). The unsaturated-zone (UZ) transport properties in the vitric Calico Hills (CHv) are discussed, as are colloidal transport data based on the Busted Butte UZTT, the saturated tuff, and alluvium. These values were determined through expert elicitation, direct measurements, and data analysis. The transport parameters include information on interactions of the fractures and matrix. In addition, core matrix permeability data from the Busted Butte UZTT are summarized by both percent alteration and dispersion.

April 25, 2002 April 25, 2002 The spot price of natural gas moved up most days since last Wednesday, April 17, as prices at the Henry Hub reached $3.63 per MMBtu on Tuesday - the highest price since April 3, 2002. The recent period of both warmer-than-normal weather east of the Rockies and colder-than-normal temperatures in the West resulted in above normal weather-related demand. The upward price trend reversed itself at all major market locations yesterday (4/24/02), as prices declined generally between 10 to 15 cents per MMBtu with prices at the Henry Hub declining 10 cents to $3.53. On the NYMEX, the settlement price for May delivery, which had increased almost every day since April 16, peaked on Tuesday, then declined sharply in yesterday's trading-moving down over 17 cents-to settle at $3.419 per MMBtu. Net additions to storage were estimated to have been 69 Bcf in the third week of April, well above the previous 5-year average. The spot price for West Texas (WTI) crude oil increased to $26.28 per barrel, or $4.47 per MMBtu.

Natural gas pipeline technology overview.  

SciTech Connect (OSTI)

The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by transmission companies. Compressor stations at required distances boost the pressure that is lost through friction as the gas moves through the steel pipes (EPA 2000). The natural gas system is generally described in terms of production, processing and purification, transmission and storage, and distribution (NaturalGas.org 2004b). Figure 1.1-2 shows a schematic of the system through transmission. This report focuses on the transmission pipeline, compressor stations, and city gates.

The Henry Hub spot price increased 14 cents per MMBtu to $6.63. The New York Mercantile Exchange (NYMEX) futures contract for June delivery at the Henry Hub was higher on the week by about 5 cents per MMBtu, closing yesterday (May 11) at $6.683. Natural gas in storage as of Friday, May 6, increased to 1,509 Bcf, which is 22.3 percent above the 5-year average. Before declining sharply yesterday, crude oil spot prices appeared to be supporting higher natural gas prices, with the West Texas Intermediate (WTI) price increasing more than $1.50 per barrel since Wednesday (May 4) to over $52. The net change in the WTI price on the week was 17 cents per MMBtu, or less than 1 percent, as the price dropped $1.37 per barrel yesterday to $50.39 per barrel, or $8.69 per MMBtu.

For the week (Wednesday-Wednesday), prices at the Henry Hub fell 44 cents or 9 percent to $4.68 per MMBtu. Lighter cooling demand for natural gas owing to the Labor Day holiday weekend and milder temperatures east of the Rockies likely contributed to the declines. Yesterday (Wednesday, September 3), the price of the NYMEX futures contract for October delivery at the Henry Hub was almost 19 cents less than last Wednesday's price. Natural gas in storage increased to 2,389 Bcf as of August 29, which is 7 percent below the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil moved down $1.75 per barrel or about 6 percent since last Wednesday to $29.43 per barrel or $5.07 per MMBtu.

Acoustic pursuit of invisible moving targets by cats  

Science Journals Connector (OSTI)

Head movements evoked by an invisible acoustic target were used as a metric to analyze localization of moving sources of sound in naive cats. The target was presented in the lateral sound field and moved along an arc at constant angular speeds. Head-movement trajectories were characterized by a large-magnitude orienting component that undershot the target and a tracking component elicited by the target during acoustic pursuit. The tracking component was characterized by a succession of stepwise head movements that maintained a relatively close alignment of the median plane of the head with the moving acoustic target.

Next-to-leading and resummed BFKL evolution with saturation boundary  

E-Print Network [OSTI]

We investigate the effects of the saturation boundary on small-x evolution at the next-to-leading order accuracy and beyond. We demonstrate that the instabilities of the next-to-leading order BFKL evolution are not cured by the presence of the nonlinear saturation effects, and a resummation of the higher order corrections is therefore needed for the nonlinear evolution. The renormalization group improved resummed equation in the presence of the saturation boundary is investigated, and the corresponding saturation scale is extracted. A significant reduction of the saturation scale is found, and we observe that the onset of the saturation corrections is delayed to higher rapidities. This seems to be related to the characteristic feature of the resummed splitting function which at moderately small values of x possesses a minimum.

Chapter 1 - Natural Gas Fundamentals  

Science Journals Connector (OSTI)

Natural gas is the most energy-efficient fossil fuel; it offers important energy-saving benefits when it is used instead of oil or coal. Although the primary use of natural gas is as a fuel, it is also a source of hydrocarbons for petrochemical feedstocks and a major source of elemental sulfur, an important industrial chemical. Its popularity as an energy source is expected to grow substantially in the future because natural gas can help achieve two important energy goals for the twenty-first century: providing the sustainable energy supplies and services needed for social and economic development and reducing adverse impacts on global climate and the environment in general. Natural gas consumption and trade have been growing steadily over the past two decades, and natural gas has strengthened its position in the world energy mix. Although natural gas demand declined in 2009, as a result of the economic slowdown, it is expected to resume growth in both emerging and traditional markets in the coming decades. Such increase in the near future will be driven because of additional demand in current uses, primarily power generation. There is yet little overlap between the use of natural gas and oil in all large markets. However, there are certain moves in the horizon, including the electrifying of transportation, that will push natural gas use to ever higher levels. This book gives the reader an introduction to natural gas by describing the origin and composition of natural gas, gas sources, phase behavior and properties, and transportation methods. Keywords: Absolute Open Flow, bulk modulus of elasticity, coal-bed methane, cricondenbar, cricondentherm, Expected Ultimate Recovery, gas deviation factor, higher heating value, Inflow Performance Relationship, kerogen, laminar flow, liquefied natural gas, primary thermogenic gas, pyrobitumen, secondary thermogenic gas, super-compressibility factor, thiol, Tubing Performance Curve, turbulent flow, unconventional gas resources, Wobbe Index, Wobbe Number.

Energy levels of a heavy ion moving in dense plasmas  

SciTech Connect (OSTI)

In this paper, the potential of a slowly moving test particle moving in collisional dense plasmas is studied. It is composed of the Debye-shielding potential, wake potential, and collision term. The Ritz variational-perturbational method is developed for calculating relativistic binding energy levels of a heavy ion moving in dense plasmas. Binding energy levels of a heavy ion moving in plasmas are calculated. The results show that both non-relativistic energy levels and relativistic energy levels become more negative as the temperature becomes high. They also become more negative as the number density decreasing. Relativistic correction is important for calculating binding energy levels. Both relativistic energy levels and non-relativistic energy levels vary minutely as the speed of heavy ion varies.

2 2006 (next release 2:00 p.m. on January 19, 2006) 2 2006 (next release 2:00 p.m. on January 19, 2006) Warmer-than-normal temperatures throughout the country led to lower natural gas spot prices at many trading locations in the Lower 48 States, while some markets exhibited modest increases since last Wednesday. For the week (Wednesday-Wednesday, January 4-11), the price for next-day delivery at the Henry Hub decreased 70 cents per MMBtu, or 7.6 percent to $8.55 per MMBtu. The NYMEX futures contract for February delivery at the Henry Hub settled yesterday (January 11) at $9.238 per MMBtu, which was 96 cents less than last Wednesday's price. Natural gas in storage decreased to 2,621 Bcf as of January 6, leaving the inventories at 11.8 percent above the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil moved up $0.50 per barrel or about 1 percent since last Wednesday to $63.91 per barrel or $11.02 per MMBtu. As natural gas prices have declined while crude oil prices remain above $60 per barrel, the relative position of these prices has returned to a more typical pattern, where the price of natural gas is below that of crude oil on a Btu basis. The Henry Hub spot price was 24 percent below the WTI crude oil price from the beginning of 2005 up to the point that Hurricane Katrina made landfall in late August. For the remainder of 2005, the Henry Hub spot price exceeded the WTI price by 15 percent. However, that unusual pattern of relative prices was changing by the end of 2005, and the Henry Hub spot price has been 17 percent below the WTI price on average so far in January.

X-ray CT Observations of Methane Hydrate Distribution Changes over Time in a Natural Sediment Core from the BPX-DOE-USGS Mount Elbert Gas Hydrate Stratigraphic Test Well  

SciTech Connect (OSTI)

When maintained under hydrate-stable conditions, methane hydrate in laboratory samples is often considered a stable and immobile solid material. Currently, there do not appear to be any studies in which the long-term redistribution of hydrates in sediments has been investigated in the laboratory. These observations are important because if the location of hydrate in a sample were to change over time (e.g. by dissociating at one location and reforming at another), the properties of the sample that depend on hydrate saturation and pore space occupancy would also change. Observations of hydrate redistribution under stable conditions are also important in understanding natural hydrate deposits, as these may also change over time. The processes by which solid hydrate can move include dissociation, hydrate-former and water migration in the gas and liquid phases, and hydrate formation. Chemical potential gradients induced by temperature, pressure, and pore water or host sediment chemistry can drive these processes. A series of tests were performed on a formerly natural methane-hydrate-bearing core sample from the BPX-DOE-USGS Mount Elbert Gas Hydrate Stratigraphic Test Well, in order to observe hydrate formation and morphology within this natural sediment, and changes over time using X-ray computed tomography (CT). Long-term observations (over several weeks) of methane hydrate in natural sediments were made to investigate spatial changes in hydrate saturation in the core. During the test sequence, mild buffered thermal and pressure oscillations occurred within the sample in response to laboratory temperature changes. These oscillations were small in magnitude, and conditions were maintained well within the hydrate stability zone.

Evaluating the Influence of Pore Architecture and Initial Saturation on Wettability and Relative Permeability in Heterogeneous, Shallow-Shelf Carbonates  

SciTech Connect (OSTI)

Thin (3-40 ft thick), heterogeneous, limestone and dolomite reservoirs, deposited in shallow-shelf environments, represent a significant fraction of the reservoirs in the U.S. midcontinent and worldwide. In Kansas, reservoirs of the Arbuckle, Mississippian, and Lansing-Kansas City formations account for over 73% of the 6.3 BBO cumulative oil produced over the last century. For these reservoirs basic petrophysical properties (e.g., porosity, absolute permeability, capillary pressure, residual oil saturation to waterflood, resistivity, and relative permeability) vary significantly horizontally, vertically, and with scale of measurement. Many of these reservoirs produce from structures of less than 30-60 ft, and being located in the capillary pressure transition zone, exhibit vertically variable initial saturations and relative permeability properties. Rather than being simpler to model because of their small size, these reservoirs challenge characterization and simulation methodology and illustrate issues that are less apparent in larger reservoirs where transition zone effects are minor and most of the reservoir is at saturations near S{sub wirr}. These issues are further augmented by the presence of variable moldic porosity and possible intermediate to mixed wettability and the influence of these on capillary pressure and relative permeability. Understanding how capillary-pressure properties change with rock lithology and, in turn, within transition zones, and how relative permeability and residual oil saturation to waterflood change through the transition zone is critical to successful reservoir management and as advanced waterflood and improved and enhanced recovery methods are planned and implemented. Major aspects of the proposed study involve a series of tasks to measure data to reveal the nature of how wettability and drainage and imbibition oil-water relative permeability change with pore architecture and initial water saturation. Focus is placed on carbonate reservoirs of widely varying moldic pore systems that represent the major of reservoirs in Kansas and are important nationally and worldwide. A goal of the project is to measure wettability, using representative oils from Kansas fields, on a wide range of moldic-porosity lithofacies that are representative of Kansas and midcontinent shallow-shelf carbonate reservoirs. This investigation will discern the relative influence of wetting and pore architecture. In the midcontinent, reservoir water saturations are frequently greater than 'irreducible' because many reservoirs are largely in the capillary transition zone. This can change the imbibition oil-water relative permeability relations. Ignoring wettability and transition-zone relative permeabilities in reservoir modeling can lead to over- and under-prediction of oil recovery and recovery rates, and less effective improved recovery management. A goal of this project is to measure drainage and imbibition oil-water relative permeabilities for a large representative range of lithofacies at differ ent initial water saturations to obtain relations that can be applied everywhere in the reservoir. The practical importance of these relative permeability and wettability models will be demonstrated by using reservoir simulation studies on theoretical/generic and actual reservoir architectures. The project further seeks to evaluate how input of these new models affects reservoir simulation results at varying scales. A principal goal is to obtain data that will allow us to create models that will show how to accurately simulate flow in the shallow-structure, complex carbonate reservoirs that lie in the transition zone. Tasks involved to meet the project objectives include collection and consolidation of available data into a publicly accessible relational digital database and collection of oil and rock samples from carbonate fields around the state (Task 1). Basic properties of these rocks and oils will be measured and used in wettability tests. Comparison will be performed between crude and synthetic oil wettability and

Non-linear evolution in CCFM: The interplay between coherence and saturation  

SciTech Connect (OSTI)

We solve the CCFM equation numerically in the presence of a boundary condition which effectively incorporates the non-linear dynamics. We retain the full dependence of the unintegrated gluon distribution on the coherence scale, and extract the saturation momentum. The resulting saturation scale is a function of both rapidity and the coherence momentum. In Deep Inelastic Scattering this will lead to a dependence of the saturation scale on the photon virtuality in addition to the usual x{sub Bj} dependence. At asymptotic energies the interplay between the perturbative non-linear physics, and that of the QCD coherence, leads to an interesting and novel dynamics where the saturation momentum itself eventually saturates. We also investigate various implementations of the 'non-Sudakov' form factor. It is shown that the non-linear dynamics leads to almost identical results for different form factors. Finally, different choices of the scale of the running coupling are analyzed and implications for the phenomenology are discussed.

High-speed EDM milling with moving electric arcs  

Science Journals Connector (OSTI)

A novel high-speed electrical discharge machining (EDM) milling method using moving electric arcs has been proposed in this study. We connected a copper electrode rotating rapidly around its axis and a work piece to a DC power supply to generate a moving electric arc. To ensure high relative speed of any point on the electrode with respect to the work piece, the electrode was shaped like a pipe. It was observed that the electric arcs move rapidly within the discharge gap due to the revolution of the tool electrode, removing the materials on the electrode along the track of the arc roots. To explore the characteristics of machining with moving electric arcs, an EDM milling apparatus was devised. Two planes with approximately the same roughness were machined separately by this equipment and a traditional EDM machine for comparison. It was found that a much higher material removal rate can be easily achieved by EDM milling with moving electric arcs. In the meanwhile, wear of the tool electrode in this new method is negligible, which is greatly favorable for machining accuracy. The microstructures of these surfaces were also investigated for further information.

Patch nearfield acoustic holography in a moving medium  

Science Journals Connector (OSTI)

Abstract To realize the accurate reconstruction of sound field in a moving medium under the condition of limited holographic aperture, a patch nearfield acoustic holography (NAH) in a moving medium is proposed. The proposed method not only reduces the influence caused by the limited aperture effects through sound field extrapolation, but also perfectly suits for sound field reconstruction in a moving medium by improving the shape of the modified Tikhonov regularization filter and the noise estimation method in accordance with flow effects. In the method, two cases that the flow direction is parallel to and perpendicular to the hologram surface are considered. Especially in the perpendicular case, the expression of the wavenumber component in the z direction is improved to make the proposed method suitable for the moving medium at a high Mach number. Simulations are investigated to examine the performance of the proposed method and show its advantages by comparing with NAH in a moving medium and the conventional patch NAH. It is found that, the proposed method is effective and robust at different flow velocities of the medium and different frequencies of the sound source.

Simulation of petcoke gasification in slagging moving bed reactors  

Science Journals Connector (OSTI)

A mathematical model for simulation of moving bed petcoke gasifiers was developed. The model introduces a new feed characterization method, gas-phase resistance and volatilization models. The model is validated using reported data for a slagging gasifier. Effect of feed oxygen-to-coke and steam-to-coke ratios and feed coke rates on gasification performance was examined. Slagging zone moving bed gasifier operation with very high petcoke fluxes of over 4000 kg/m2/h was possible with high petcoke conversion. Peak gas temperatures exceeded 1500 °C. Fluxes higher than 5000 kg/m2/h are limited by an approach to fluidization of small particles in the combustion zone. The moving bed gasifier performance was found superior to performance of an entrained flow gasifier (EFG) with respect to energy efficiency and oxygen consumption.

Dehydration of natural gas using solid desiccants  

Science Journals Connector (OSTI)

Natural gas is an important source of primary energy that, under normal production conditions, is saturated with water vapor. Water vapor increases natural gases' corrosivity, especially when acid gases are present. Several methods can be used to dry natural gas and, in this paper, a solid desiccant dehydrator using silica gel is considered due to its ability to provide extremely low dew points. The design analysis of a two-tower, silica gel dehydration unit to dry one million standard m3 of natural gas per day is presented in this paper and the effects of various operating parameters on the design of the unit are discussed. The study also covers the analysis of energy requirements for the regeneration of the weak desiccant bed based on some simplified assumptions and it is found that the higher the regeneration temperature, the smaller are the required quantities of regeneration gas.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

2, 2003 (next release 2:00 p.m. on June 19) 2, 2003 (next release 2:00 p.m. on June 19) Moderate temperatures across the country except in the Southwest contributed to natural gas spot prices easing 25 to 50 cents per MMBtu since Wednesday, June 4. On the week (Wednesday, June 4-Wednesday, June 11), the Henry Hub spot price dropped 35 cents per MMBtu to $6.06. The NYMEX futures contract for July delivery at the Henry Hub fell about 16 cents per MMBtu to $6.213. Natural gas in storage as of Friday, June 6, increased to 1,324 Bcf, which is 25.2 percent below the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil rose $2.36 per barrel on the week to yesterday's (June 11) closing price of $32.17 per barrel, or $5.55 per MMBtu. Prices: Natural gas spot prices at many market locations in the Lower 48 States have declined for three consecutive trading days from Friday peaks as key market areas in the Midwest and the Eastern seaboard have experienced unseasonably cool weather. Although prices remain elevated, the slackened demand for natural gas for electric generation has contributed to prices generally softening across the board. For the week, the spot price at the Henry Hub dropped about 6 percent to $6.06 per MMBtu, while other pricing points on the Gulf Coast showed slightly greater declines and fell below the $6-mark. The overall easing of prices may reflect also the slightly improving storage picture as injections in 7 of the past 8 weeks have exceeded the 5-year average with a record net addition reported last Thursday. Although the storage refill season started slowly, injections have increased considerably, with at least one major interstate pipeline serving the Northeast, Tennessee Gas Pipeline, announcing restrictions to shippers due to injection nominations exceeding capacity. The spot price at Tennessee Gas Pipeline's Zone 6, which serves major citygates in New York and other Northeastern states, this week fell 47 cents per MMBtu to $6.30. In contrast to the East, prices in the West moved higher early in the week, as maintenance on El Paso Natural Gas in the San Juan Basin restricted deliveries from the region and a heat wave sparked buying at pricing locations in California and New Mexico. The spot price at the Southern California border surged 61 cents per MMBtu on Monday to $5.78, but has since dropped to $5.51, which is a net decline of 51 cents since Wednesday, June 4.

Structure and electronic properties of saturated and unsaturated gallium nitride nanotubes  

SciTech Connect (OSTI)

The atomic and electronic structures of saturated and unsaturated GaN nanotubes along the [001] direction with (100) lateral facets are studied using first-principles calculations. Atomic relaxation of nanotubes shows that appreciable distortion occurs in the unsaturated nanotubes. All the nanotubes considered, including saturated and unsaturated ones, exhibit semiconducting, with a direct band gap. Surface states arisen from the threefold-coordinated N and Ga atoms at the lateral facets exist inside the bulk-like band gap. When the nanotubes saturated with hydrogen, these dangling bond bands are removed from the band gap, but the band gap decreases with increasing the wall thickness of the nanotubes.

Femtosecond all-optical parallel logic gates based on tunable saturable to reverse saturable absorption in graphene-oxide thin films  

SciTech Connect (OSTI)

A detailed theoretical analysis of ultrafast transition from saturable absorption (SA) to reverse saturable absorption (RSA) has been presented in graphene-oxide thin films with femtosecond laser pulses at 800?nm. Increase in pulse intensity leads to switching from SA to RSA with increased contrast due to two-photon absorption induced excited-state absorption. Theoretical results are in good agreement with reported experimental results. Interestingly, it is also shown that increase in concentration results in RSA to SA transition. The switching has been optimized to design parallel all-optical femtosecond NOT, AND, OR, XOR, and the universal NAND and NOR logic gates.

Oppenheimer-Snyder Collapse in Moving-Puncture Coordinates  

E-Print Network [OSTI]

Moving-puncture coordinates are commonly used in numerical simulations of black holes. Their properties for vacuum Schwarzschild black holes have been analyzed in a number of studies. The behavior of moving-puncture coordinates in spacetimes containing matter, however, is less well understood. In this paper we explore the behavior of these coordinates for Oppenheimer-Snyder collapse, i.e., the collapse of a uniform density, pressureless sphere of dust initially at rest to a black hole. Oppenheimer-Snyder collapse provides a stringent test of the singularity-avoiding properties of moving-puncture coordinates, since the singularity can form more quickly than it would for matter with pressure. Our results include analytical expressions for the matter density, lapse function, and mean curvature at early times, as well as interesting limits for later times. We also carry out numerical simulations to obtain the full solution and these show that, even in the absence of pressure, moving-puncture coordinates are able to avoid the singularity. At late times the geometry settles down to a trumpet slice of a vacuum black hole.

Gasoline and Diesel Fuel Update (EIA)

31, 2002 (next release 2:00 p.m. on November 7) 31, 2002 (next release 2:00 p.m. on November 7) Spot and futures prices fluctuated over the past week (Wednesday, October 23 to Wednesday, October 30), with cash prices moving up from 6 to 35 cents per MMBtu at most market locations in response to rising demand from colder-than-normal temperatures, while futures prices for contracts for delivery through the impending heating season drifted lower. At the Henry Hub, the average spot price rose 9 cents from the previous Wednesday (October 23) to $4.33 per MMBtu in yesterday's (October 30) trading. The expired near-month contract for November delivery ended trading on Tuesday, October 29 at $4.126 per MMBtu, recording a net gain of $0.085 since beginning as the prompt month contract on September 27. The new near-month contract, for December delivery, began with a gain of just under 13 cents, to settle at $4.389 per MMBtu. Natural gas in storage as of Friday, October 25 increased to 3,172 Bcf, which exceeds the 5-year average by 6.3 percent. In contrast to natural gas spot prices, crude oil prices continued to soften. After dropping over $1 per barrel the previous week, the average spot price for West Texas Intermediate (WTI) crude oil fell another $1.36 per barrel to end trading on Wednesday, October 30 at $26.85, or $4.63 per MMBtu.

May 6 (next release 2:00 p.m. on May 13) May 6 (next release 2:00 p.m. on May 13) Upward pressure on spot and futures natural gas prices continued for a second consecutive week (Wednesday-Wednesday, April 28-May 5), owing to continuing concerns over gas supplies and higher crude oil prices. A 42-cent per MMBtu price increase at the Henry Hub on Tuesday (May 4) appeared to be related to the increase in futures prices the previous day, when the near-month contract moved past the $6-mark to a close of $6.231. The Henry Hub spot price increase on Tuesday and a 2-cent increase last Friday (April 30) were more than enough to offset declines in the other three trading sessions this week, resulting in a net gain on the week of 30 cents per MMBtu. The NYMEX futures contract for June delivery at the Henry Hub was higher on the week by about 34 cents per MMBtu, closing yesterday (May 5) at $6.31. Natural gas in storage as of Friday, April 30, increased to 1,227 Bcf, which is 2.2 percent below the 5-year average. Owing to geopolitical concerns and perceived low gasoline supplies heading into the summer driving season, crude oil prices rose to almost $40 per barrel this week. The spot price for West Texas Intermediate (WTI) crude oil increased $2.46 per barrel on the week to yesterday's closing price of $39.69 per barrel, or $6.84 per MMBtu.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

Holiday Notice: Holiday Notice: Due to the federal holiday in observance of Martin Luther King Day on Monday, January 21, 2002, the next issue of the Natural Gas Weekly Update will be published on Tuesday, January 22, 2002. Overview: Monday, January 14, 2002 Natural gas prices were generally lower last week as the fundamentals of ample working gas in storage and very little temperature-driven swing demand dominated the market. With little in the way of market-changing developments, trading in both the spot and futures markets tended to occur in relatively small price ranges throughout the week. The warming trend begun late in the previous week continued nearly unabated through last week, with the heavy gas-consuming areas of the Midwest and Northeast recording many of the greatest deviations above daily normal temperatures. Philadelphia, New York City, and Buffalo, NY had at least 3 days of temperatures that were 10 or more degrees above normal; Chicago's temperature reached an unusually warm 26 degrees above normal on Wednesday. (See Temperature Map) (See Deviation Map) Spot prices at the Henry Hub moved down moderately from the previous week, ending trading on Friday at $2.31, down 5 cents from the previous Friday. On the NYMEX, the futures contract for February delivery at the Henry Hub declined by $0.071 from the previous Friday, settling on Friday, January 11 at $2.204 per MMBtu. The spot price for West Texas Intermediate crude oil also fell, dipping below $20 per barrel for the first time in the New Year, ending trading last Friday at $19.67 per barrel, or $3.39 per MMBtu, down $1.80 per barrel, or $0.31 per MMBtu, from Friday, January 4.

October 2, 2003 (next release 2:00 p.m. on October 9) October 2, 2003 (next release 2:00 p.m. on October 9) A cold front moved through the Midwest and parts of the Northeast this week, but it failed to bring sustained higher prices. Seasonally mild temperatures in most other areas of the country and little in the way of tropical storm activity resulted in prices easing 20 cents per MMBtu or less since Wednesday, September 24. On the week (Wednesday, September 24-Wednesday, October 1), the Henry Hub spot price dropped 12 cents per MMBtu to $4.47. The NYMEX futures contract for October delivery expired on Friday, September 26, at $4.430, while the contract for November lost about 8 cents on the week to close at $4.677 yesterday (October 1). Natural gas in storage as of Friday, September 26, increased to 2,788 Bcf, which is 1.9 percent below the 5-year average inventory for the report week. The spot price for West Texas Intermediate (WTI) crude oil rose $1.24 per barrel on the week to yesterday's (October 1) closing price of $29.43 per barrel, or $5.07 per MMBtu.

Gasoline and Diesel Fuel Update (EIA)

Monday, January 28, 2002 Monday, January 28, 2002 Natural gas prices generally declined last week as mild temperatures continued in most of the country and working gas storage stocks remain at very high levels. Spot prices at most major markets that serve the eastern two-thirds of the country ended the week down from the previous Friday with weather forecasts for the past weekend calling for daytime temperatures to be in the mid 50s to the low 60s in an area stretching from Chicago to Boston. At the Henry Hub prices moved down 9 cents on Friday to end at $2.04 per MMBtu--$0.25 below the previous Friday. The National Weather Service's (NWS) latest 6- to 10-day forecast is calling for above normal temperatures to continue through this week in most areas east of the Mississippi River. (See Temperature Map) (See Deviation Map) At the NYMEX futures market, the February contract continued to trend down as it ended the week trading at $2.037 per MMBtu-off almost $0.20 from previous Friday. The spot price for West Texas Intermediate (WTI) crude oil gained almost $1.80 per barrel reaching $19.80 on Friday or about $3.40 per MMBtu.

17 (next release 2:00 p.m. on February 24) 17 (next release 2:00 p.m. on February 24) Moderate temperatures throughout most of the country this week contributed to widespread price decreases at trading locations in the Lower 48 States. However, most price declines were limited to less than 20 cents per MMBtu as higher crude oil prices appeared to support prices across the energy complex. For the week (Wednesday-Wednesday, February 9-16), the price for next-day delivery at the Henry Hub slipped 9 cents per MMBtu, or about 1 percent to $6.11. The NYMEX futures contract for March delivery at the Henry Hub yesterday (February 16) settled at $6.109 per MMBtu, which is 5.6 cents less than last Wednesday's price. Natural gas in storage decreased to 1,808 Bcf as of February 11, which is 20.9 percent above the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil moved up $2.90 per barrel or about 6 percent since last Wednesday to $48.35 per barrel or $8.34 per MMBtu.

9, 2004 (next release 2:00 p.m. on February 5) 9, 2004 (next release 2:00 p.m. on February 5) Spot prices in most regional markets ended the week (Wednesday-Wednesday, January 21-28) lower, despite severe cold in the Northeast beginning Friday (January 23) and continuing through the weekend. As a result, prices in the Northeast market proved the major exception to the downward trend, as cash prices moved up sharply at most locations in the region. At the Henry Hub, the spot price was 23 cents per MMBtu lower on the week, or about 4 percent, ending with yesterday's (Wednesday, January 28) level of $6.04. At the New York Mercantile Exchange (NYMEX), the futures contract for February delivery showed a modest gain of nearly 6 cents on its final day of trading, closing out at $5.775 per MMBtu. The contract for March delivery assumes the near-month position beginning today (Thursday, January 29). The Energy Information Administration (EIA) reported that natural gas inventories were 2,063 Bcf as of Friday, January 23, which is 8.6 percent greater than the previous 5-year (1999-2003) average. West Texas Intermediate crude oil on the spot market fell $1.90 per barrel, or $0.26 per MMBtu, since last Wednesday (January 21), ending trading yesterday at $33.63 per barrel, or $5.80 per MMBtu.

Gasoline and Diesel Fuel Update (EIA)

11, 2002 11, 2002 On Friday, spot gas traded at the Henry Hub for $2.20 per MMBtu, marking no change from the price on the previous Friday. Last week spot prices at the Henry Hub traded within a tight range of $2.14-$2.20 per MMBtu. Temperatures in much of the country returned to above normal in the second half of the week and the National Weather Service's (NWS) latest 6-to 10-day forecast called for this pattern to continue through the weekend and all of this week. (See Temperature Map) (See Deviation Map) This dominant pattern of above normal temperatures has resulted in heating degree days thus far this winter that are 16 percent lower than normal. At the NYMEX, the settlement price for the March contract ended the week up almost 5 cents at $2.191 per MMBtu. Natural gas stocks remained well above last year's level as estimated net withdrawals were 82 Bcf during the last week of January. The spot price for West Texas Intermediate (WTI) crude oil moved down 15 cents last week and ended Friday trading at $20.25 per barrel or $3.49 per MMBtu.

2 (next release 2:00 p.m. on August 19) 2 (next release 2:00 p.m. on August 19) Natural gas spot and futures prices moved lower on the week (Wednesday to Wednesday, August 4-11), as unseasonably cool temperatures prevailed in most high gas-consuming regions of the nation. At the Henry Hub, the spot price declined 6 cents on the week, or just over 1 percent, to yesterday's (Wednesday, August 11) level of $5.64 per MMBtu. On the NYMEX, the futures contract for September delivery edged down nearly 5 cents per MMBtu, or about 1 percent, to settle yesterday at $5.614. EIA reported that inventories were 2,452 Bcf as of Friday, August 6, which is 5.0 percent greater than the average for the previous 5 years (1999-2003). The spot price for West Texas Intermediate (WTI) crude oil rose sharply in last Thursday's (August 5) trading to top $44 per barrel and stayed above that level for 4 of the 5 trading days in the week. The WTI spot price ended trading yesterday at $44.72 per barrel, or $7.71 per MMBtu, which is $1.99 per barrel, or almost 5 percent, higher than last Wednesday's (August 4) price.

June 3 (next release 2:00 p.m. on June 10) June 3 (next release 2:00 p.m. on June 10) Natural gas futures prices moved down during the holiday-shortened trading week (Wednesday to Wednesday, May 26-June 2) joined by falling spot prices in markets east of the Rocky Mountains, while cash prices in western market locations rose appreciably. The spot price at the Henry Hub declined 19 cents per MMBtu on the week, or nearly 3 percent, to $6.51. On the New York Mercantile Exchange (NYMEX), the settlement price for the futures contract for July delivery fell by $0.213 to $6.519 per MMBtu. EIA reported that inventories were 1,564 Bcf as of Friday, May 28, which is 0.5 percent less than the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil was 64 cents per barrel (11 cents per MMBtu) below its level of last Wednesday (May 26), ending trading yesterday (June 2) at $39.96 ($6.89 per MMBtu), after hitting a record high spot price of $42.33 ($7.30 per MMBtu) on Tuesday.

25, 2007 (next release 2:00 p.m. on November 1, 2007) 25, 2007 (next release 2:00 p.m. on November 1, 2007) Natural gas spot and futures prices generally decreased this report week (Wednesday to Wednesday, October 17-24), as moderate weather prevailed across much of the Lower 48 States. Although tropical storms entering the Gulf of Mexico production region-evidenced by a system currently moving through the Caribbean-could still disrupt supplies, the passing of at least the most active part of the hurricane season may help explain the price declines. On the week the Henry Hub spot price decreased $1.01 per MMBtu to $6.10. At the New York Mercantile Exchange (NYMEX), prices for futures contracts also registered significant decreases. The futures contract for November delivery declined about 49 cents per MMBtu on the week to $6.972. Working gas in storage is well above the 5-year average for this time year, indicating a healthy supply picture ahead of the winter heating season. As of Friday, October 19, working gas in storage was 3,443 Bcf, which is 7.2 percent above the 5-year (2002-2006) average. The spot price for West Texas Intermediate (WTI) crude oil increased $1.11 per barrel, ending trading yesterday at $88.30, or $15.22 per MMBtu.

12 2002 (next release 2:00 p.m. on December 19) 12 2002 (next release 2:00 p.m. on December 19) Spot prices generally moved higher for the week (Wednesday, December 4 to Wednesday, December 11) with exceptions at several Northeast locations, while futures prices experienced robust gains, particularly for contracts for delivery through the end of the heating season. Unusually cold temperatures accompanied the heating season's first significant and widespread snow storm late last week, and temperatures plunged again ahead of the ice storm of Tuesday and Wednesday. At the Henry Hub, the average spot price gained 41 cents for the week, ending trading yesterday (Wednesday, December 11) at $4.64 per MMBtu. Since last Wednesday, the NYMEX futures contract for delivery in January 2003 gained $0.411 per MMBtu, settling yesterday at $4.709. Natural gas in storage as of Friday, December 6, decreased to 2,794 Bcf, which is 2.9 percent below the 5-year average. The price of West Texas Intermediate crude oil gained 69 cents per barrel for the week, ending trading yesterday at $27.49 per barrel, or $4.74 per MMBtu.

11, 2003 (next release 2:00 p.m. on September 18) 11, 2003 (next release 2:00 p.m. on September 18) Spot natural gas prices increased 5 to 15 cents in most regional markets for the week (Wednesday to Wednesday, September 3-10). The Henry Hub spot price gained 10 cents on the week, ending trading yesterday (Wednesday, September 10) at $4.78 per MMBtu. Futures prices were up as well, with the gains owing almost entirely to yesterday's large price increases. The NYMEX futures contract for October delivery moved up nearly 24 cents in yesterday's trading, and for the week gained $0.278 per MMBtu with its settlement yesterday at $4.968. The Energy Information Administration (EIA) reported that inventories were 2,486 Bcf as of Friday, September 5, which is 5.5 percent less than the 5-year (1998-2002) average. The spot price for West Texas Intermediate (WTI) crude oil fell below $29 per barrel for the first time since late June, lingering in the high-$28s for the first 3 days of the week before regaining nearly all of its decreases on Tuesday and Wednesday. WTI crude oil ended the week at $29.41 per barrel ($5.07 per MMBtu), just 2 cents per barrel below the week-ago price.

During the report week (Wednesday-Wednesday, April 11-18), the Henry Hub spot price declined 42 cents per MMBtu to $7.54. At the New York Mercantile Exchange (NYMEX), prices for futures contracts also were lower. The futures contract for May delivery decreased 35.8 cents per MMBtu on the week to $7.497. Working gas in storage as of Friday, April 13, was 1,546 Bcf, which is 22.1 percent above the 5-year (2002-2006) average. The spot price for West Texas Intermediate (WTI) crude oil increased $1.16 per barrel on the week to $63.14, or $10.89 per MMBtu.

Hurricane Humberto is still active near the Texas-Louisiana border at the time of this writing, and Tropical Depression 8 in the South Atlantic is apparently moving toward Puerto Rico and the general direction of the Gulf of Mexico (where these storms might cause energy-producing platforms to be evacuated and supplies to be shut in). However, companies have not yet announced significant shut-in production or damage from the weather. On the week the Henry Hub spot price increased 32 cents per MMBtu to $6.13. At the New York Mercantile Exchange (NYMEX), prices for futures contracts also registered significant increases. The futures contract for October delivery rose 63.3 cents per MMBtu on the week to $6.438. Working gas in storage as of Friday, September 7, was 3,069 Bcf, which is 9.3 percent above the 5-year (2002-2006) average. The spot price for West Texas Intermediate (WTI) crude oil recorded yet another record high, increasing $4.11 per barrel on the week to $79.85, or $13.77 per MMBtu.

At the Henry Hub, the spot price declined 37 cents, or nearly 6 percent, from last Wednesday's level, averaging $5.91 per MMBtu in yesterday's (Wednesday, July 14) trading. On the futures market, the NYMEX futures contract for August delivery declined most days, dipping below $6 in Monday trading for the first time in more than two months. Despite slight increases over the next two days, the August contract settled yesterday at $5.977 per MMBtu, down $0.393 from the previous Wednesday (July 7). EIA reported that inventories were 2,155 Bcf as of Friday, July 9, which is 2.6 percent greater than the 5-year average. Primarily on the strength of yesterday's $1.43 per barrel increase, the spot price for West Texas Intermediate crude oil exceeded $40 for the first time in more than 6 weeks, gaining $1.80 per barrel on the week to trade yesterday at $40.98, or $7.07 per MMBtu.

At the Henry Hub, the spot price eased down 2 cents on the week, to $5.33 per MMBtu. On the NYMEX, the futures contract for March delivery increased $0.096 per MMBtu for the week, ending trading yesterday (February 18) at $5.356. EIA reported that natural gas inventories declined to 1,431 Bcf as of Friday, February 13, which is 6.2 percent lower than the previous 5-year (1999-2003) average. The spot price for West Texas Intermediate crude oil rose each day of the holiday-shortened week, and ended trading yesterday with an increase for the week of $1.49 per barrel ($0.24 per MMBtu), or a little over 4 percent, to $35.42 ($6.11 per MMBtu).

1, 2002 1, 2002 Lingering low temperatures last week prompted spot prices at the Henry Hub to start the week up sharply gaining 19 cents to trade on Monday at $2.68 per MMBtu. Prices then declined sharply before rebounding on Thursday and Friday to end the week at $2.81 per MMBtu-32 cents higher than the previous Friday. Prices on the NYMEX futures market moved up most days to end the week up almost $0.45 per MMBtu at $2.800. Temperatures moderated in many parts of the country last week and rose to the 60s and 70s on Friday and Saturday in much of the Northeast. The latest National Weather Service (NWS) 6- to 10-day forecast calls for cool temperatures in the Midwest but for above normal temperatures to return to the Northeast. (See Temperature Map) (See Deviation Map) Net withdrawals from stocks increased to132 Bcf during the last week of February, which is more than double the level of a week earlier. Even though natural gas stocks continue to be 45 percent, or 577 Bcf, above the previous 5-year average, reports of the increase in storage withdrawals may have contributed to last week's spot and futures contract price rise. The price for West Texas Intermediate (WTI) crude oil rose above $23 per barrel on Tuesday and ended trading on Friday at its highest level since September 21, 2001--$23.87 per barrel, or $4.15 per MMBtu.

23, 2002 (next release 2:00 p.m. on May 30) 23, 2002 (next release 2:00 p.m. on May 30) Natural gas spot and futures prices trended down for the week (Wednesday to Wednesday, May 15-22). The cold front that moved into major gas-consuming areas of the Midwest and Northeast for the weekend and lingered into the first part of this week had minimal impact on prices. At the Henry Hub, the average spot price fell 24 cents for the week to $3.38 per MMBtu. On the NYMEX, the settlement price of the near-month contract (June delivery) declined for 5 straight trading sessions before recording a small increase of $0.064 per MMBtu in May 22 trading, to settle at $3.459. The spot price for West Texas Intermediate (WTI) crude oil, which had held at or above $28 per barrel since last Thursday, fell nearly $1 on Tuesday, May 21, following the American Petroleum Institute's announcement of an unexpected build in crude oil stocks of 5.5 million barrels for the week ended Friday, May 17. For the week (May 15-22), the WTI price was down $0.99, at $27.01 per barrel, or $4.66 per MMBtu.

Motion compensation method for moving pictures with binary shape  

Science Journals Connector (OSTI)

This paper describes a motion compensation method for arbitrarily shaped moving visual objects. To utilise both the inter-frame correlation and the texture-shape correlation, we use macroblock-based motion compensation for binary shape coding as well as texture coding. To efficiently achieve motion compensation for a moving binary shape, we introduce extra motion vectors for the shape coding in addition to the texture motion vectors, where the shape motion vectors are coded by referring to the texture motion vectors. The proposed method can successfully save more than 50% of the number of bits in comparison with the intra-only method. The effectiveness of the proposed method has been established through MPEG4 standardisation activity, and the proposed motion-compensation framework has been adopted by the MPEG-4 visual coding standard (ISO 14496-2).

Location-based vehicular moving predictions for wireless communication  

Science Journals Connector (OSTI)

In cellular networks, an important practical issue is how to ensure high-quality service. We assume all Base Stations (BSs) have a Geographic Information System (GIS) that has a street map with all BSs and all vehicles have a Global Positioning System (GPS), which acquires data for vehicle speed, direction, and location and sends this information to the nearest BS periodically when communicating within the BS. Based on this vehicle information, a BS checks whether an intersection has a traffic light, determines the traffic light pattern, predicts where vehicles may move, determines whether vehicles may move into another region, and informs the BS to reserve resources for a hand-off. Based on GPS and GIS information, the proposed method, TSDMP, has a lower prediction error rate in predicting traffic light patterns and vehicle movements than other techniques.

Moving granular-bed filter development program. Topical report  

SciTech Connect (OSTI)

Advanced, coal-based, power plants, such as IGCC and Advanced-PFBC, are currently nearing commercial demonstration. These power plant technologies require hot gas filtration as part of their gas cleaning trains. Ceramic barrier filters are the major filter candidates being developed for these hot gas cleaning applications. While ceramic barrier filters achieve high levels of particle removal, concerns exist for their reliability and operability in these applications. An alternative hot gas filtration technology is the moving granular bed filter. An advanced, moving granular bed filter has been conceived, and early development activities performed by the Westinghouse Electric Corporation, Science and Technology Center. This document reports on the Base Contract tasks performed to resolve the barrier technical issues for this technology. The concept, the Standleg Moving Granular Bed Filter (SMGBF) has a concurrent downward, gas and bed media flow configuration that results in simplified features and improved scaleup feasibility compared to alternative designs. Two modes of bed media operation were assessed in the program: once-through using pelletized power plant waste as bed media, and recycle of bed media via standleg and pneumatic transport techniques. Cold Model testing; high-temperature, high-pressure testing; and pelletization testing using advanced power plant wastes, have been conducted in the program. A commercial, economic assessment of the SMGBF technology was performed for IGCC and Advanced-PFBC applications. The evaluation shows that the barrier technical issues can be resolved, and that the technology is potentially competitive with ceramic barrier filters.

Determination of Water Saturation in Relatively Dry Porous Media Using Gas-phase Tracer Tests  

SciTech Connect (OSTI)

Soil desiccation (drying), involving water evaporation induced by dry air injection and extraction, is a potentially robust remediation process to slow migration of inorganic or radionuclide contaminants through the vadose zone. The application of gas-phase partitioning tracer tests has been proposed as a means to estimate initial water volumes and to monitor the progress of the desiccation process at pilot-test and field sites. In this paper, tracer tests have been conducted in porous medium columns with various water saturations using sulfur hexafluoride as the conservative tracer and tricholorofluoromethane and difluoromethane as the water-partitioning tracers. For porous media with minimal silt and/or organic matter fractions, tracer tests provided reasonable saturation estimates for saturations close to zero. However, for sediments with significant silt and/or organic matter fractions, tracer tests only provided satisfactory results when the water saturation was at least 0.1 - 0.2. For dryer conditions, the apparent tracer retardation increases due to air – soil sorption, which is not included in traditional retardation coefficients derived from advection-dispersion equations accounting only for air – water partitioning and water – soil sorption. Based on these results, gas-phase partitioning tracer tests may be used to determine initial water volumes in sediments, provided the initial water saturations are sufficiently large. However, tracer tests are not suitable for quantifying moisture content in desiccated sediments.

MOBILIZATION AND CHARACTERIZATION OF COLLOIDS GENERATED FROM CEMENT LEACHATES MOVING THROUGH A SRS SANDY SEDIMENT  

SciTech Connect (OSTI)

Naturally occurring mobile colloids are ubiquitous and are involved in many important processes in the subsurface zone. For example, colloid generation and subsequent mobilization represent a possible mechanism for the transport of contaminants including radionuclides in the subsurface environments. For colloid-facilitated transport to be significant, three criteria must be met: (1) colloids must be generated; (2) contaminants must associate with the colloids preferentially to the immobile solid phase (aquifer); and (3) colloids must be transported through the groundwater or in subsurface environments - once these colloids start moving they become 'mobile colloids'. Although some experimental investigations of particle release in natural porous media have been conducted, the detailed mechanisms of release and re-deposition of colloidal particles within natural porous media are poorly understood. Even though this vector of transport is known, the extent of its importance is not known yet. Colloid-facilitated transport of trace radionuclides has been observed in the field, thus demonstrating a possible radiological risk associated with the colloids. The objective of this study was to determine if cementitious leachate would promote the in situ mobilization of natural colloidal particles from a SRS sandy sediment. The intent was to determine whether cementitious surface or subsurface structure would create plumes that could produce conditions conducive to sediment dispersion and mobile colloid generation. Column studies were conducted and the cation chemistries of influents and effluents were analyzed by ICP-OES, while the mobilized colloids were characterized using XRD, SEM, EDX, PSD and Zeta potential. The mobilization mechanisms of colloids in a SRS sandy sediment by cement leachates were studied.

Observation of coherence revival and fidelity saturation in a delta-kicked rotor potential  

E-Print Network [OSTI]

We experimentally investigate the effect of atomic $\\delta$-kicked rotor potentials on the mutual coherence between wavepackets in an atom interferometer. The differential action of the kicked rotor degrades the mutual coherence, leading to a reduction of the interferometry fringe visibility; however, when the repetition rate of the kicked rotor is at or near the quantum resonance, we observe revival of matter-wave coherence as the number of kicks increases, resulting in non-vanishing coherence in the large kick number limit. This coherence saturation effect reflects a saturation of fidelity decay due to momentum displacements in deep quantum regime. The saturation effect is accompanied with an invariant distribution of matter-wave coherence under the kicked rotor perturbations.

The average spot price at the Henry Hub yesterday (Wednesday, October 2), at $4.24 per MMBtu, was 49 cents higher than a week ago. However, the amount of gas actually delivered at October 2 prices is likely to be small, as operations at the Henry Hub near Erath, LA, were essentially shut down for at least 48 hours because of Lili's impending arrival. On the NYMEX, the expiring near-month contract for October delivery ended trading on Thursday, September 26 with a sizeable gain of over 19 cents per MMBtu, closing at $3.686. Taking over as the near-month contract, the futures contract for November delivery promptly gained $0.152 per MMBtu to settle at $4.041 on Friday. Natural gas in storage reached 3,038 Bcf on September 27, which exceeds the average of the past 5 years by 10 percent. With continuing turmoil in the Middle East and uncertainty surrounding the conflict with Iraq over weapons inspections keeping oil prices high, the spot price of West Texas Intermediate (WTI) crude oil hovered above $30 per barrel throughout the week. WTI ended trading Wednesday (October 2) at an average of $30.59 per barrel, or about $5.27 per MMBtu, down a dime per barrel from the previous Wednesday.

Simulations of electron cloud build-up and saturation in the APS  

SciTech Connect (OSTI)

In studies with positron beams in the Advanced Photon Source, a dramatic amplification was observed in the electron cloud for certain bunch current and bunch spacings. In modeling presented previously, we found qualitative agreement with the observed beam-induced multipacting condition, provided reasonable values were chosen for the secondary electron yield parameters, including the energy distribution. In this paper, we model and discuss the build-up and saturation process observed over long bunch trains at the resonance condition. Understanding this saturation mechanism in more detail may have implications for predicting electron cloud amplification, multipacting, and instabilities in future rings.

Analysis of saturation phenomena in Cerenkov free-electron lasers with a planar waveguide  

SciTech Connect (OSTI)

In this paper, the operation of the stimulated emission in Cerenkov free-electron laser (CFEL) is studied on the basis of the modulations of electron velocity and density by the electromagnetic (EM) field. The influence of the electron relaxation, due to mutual electrons collisions, on the electron dynamics is taken into account. We investigate the growth characteristics of Cerenkov laser operating in the small-signal and saturation regimes. In the saturation regime, the effect of velocity reduction of the electron beam on the gain dynamics is demonstrated. We also show that our results match with those of other well-known treatments in the small-signal gain limit.

Enhanced quantum coherence in graphene caused by Pd cluster deposition and its zero-temperature saturation  

E-Print Network [OSTI]

We report on the unexpected increase in the dephasing lengths of a graphene sheet caused by the deposition of Pd nanoclusters, as demonstrated by weak localization measurements. The dephasing lengths reached saturated values at low temperatures, which was essentially related to zero-temperature dephasing. The temperature-dependent dephasing was described by 1/(TlnT) and the saturated dephasing period was found to depend on {\\sigma}le, revealing disorder-induced zero-temperature dephasing in our defect-enriched graphene. Taken together with our theoretical calculations, we suggest that competition between surface scattering and charge transfer leads to the improvement of quantum coherence in cluster-decorated graphene.

Saturation of light?induced defects in a?Si:H  

Science Journals Connector (OSTI)

The steady?state defect density in hydrogenated amorphous silicon (a?Si:H) under illumination was investigated for a wide range of illumination intensities and temperatures. The saturation defect density under illumination is both temperature and light intensity dependent. A chemical equilibrium model for light?induced defect generation is proposed. According to the model defect generation is enhanced under illumination due to the reduction of the defect formation energy when the bands are populated by photogenerated carriers. Defect generation is a self limiting process and the defect density reaches a saturation value at long illumination time despite the existence of an extended distribution of defect formation sites.

Apparatus for weighing and identifying characteristics of a moving vehicle  

DOE Patents [OSTI]

Apparatus for weighing a vehicle in motion is provided by employing a plurality of elongated fiber-optic sensors defined by an optical fiber embedded in an encasement of elastomeric material and disposed parallel to each other on the roadway in the path of moving vehicles. Each fiber-optic sensor is provided with contact grid means which can be selectively altered to provide the fiber-optic sensors with sensitivities to vehicular weight different from each other for weighing vehicles in an extended weight range. Switch means are used in conjunction with the fiber-optic sensors to provide signals indicative of the speed of the moving vehicle, the number of axles on the vehicle, weight distribution, tire position, and the wheelbase of the vehicle. The use of a generally N-shaped configuration of switch means also provides a determination of the number of tires on each axle and the tire footprint. When switch means in this configuration are formed of optical fibers, the extent of light transmission through the fibers during contact with the tires of the vehicle is indicative of the vehicle weight. 15 figures.

Newton's aerodynamic problem in media of chaotically moving particles  

E-Print Network [OSTI]

We study the problem of minimal resistance for a body moving with constant velocity in a rarefied medium of chaotically moving point particles, in Euclidean space R^d. The particles distribution over velocities is radially symmetric. Under some additional assumptions on the distribution function, the complete classification of bodies of least resistance is made. In the case of three and more dimensions there are two kinds of solutions: a body similar to the solution of classical Newton's problem and a union of two such bodies ``glued together'' by rear parts of their surfaces. In the two-dimensional case there are solutions of five different types: (a) a trapezium; (b) an isosceles triangle; (c) the union of a triangle and a trapezium with common base; (d) the union of two isosceles triangles with common base; (e) the union of two triangles and a trapezium. The cases (a)--(d) are realized for any distribution of particles over velocities, and the case (e) is only realized for some distributions. Two limit cases are considered, where the average velocity of particles is big and where it is small as compared to the body's velocity. Finally, using the obtained analytical results, we study numerically a particular case: the problem of body's motion in a rarefied homogeneous monatomic ideal gas of positive temperature in R^2 and in R^3.

Moving boundary approximation for curved streamer ionization fronts: Solvability analysis  

Science Journals Connector (OSTI)

The minimal density model for negative streamer ionization fronts is investigated. An earlier moving boundary approximation for this model consisted of a “kinetic undercooling” type boundary condition in a Laplacian growth problem of Hele-Shaw type. Here we derive a curvature correction to the moving boundary approximation that resembles surface tension. The calculation is based on solvability analysis with unconventional features, namely, there are three relevant zero modes of the adjoint operator, one of them diverging; furthermore, the inner-outer matching ahead of the front must be performed on a line rather than on an extended region; and the whole calculation can be performed analytically. The analysis reveals a relation between the fields ahead and behind a slowly evolving curved front, the curvature and the generated conductivity. This relation forces us to give up the ideal conductivity approximation, and we suggest to replace it by a charge neutrality approximation. This implies that the electric potential in the streamer interior is no longer constant but solves a Laplace equation; this leads to a Muskat-type problem.

Optical saturation and extraction from the chemical oxygen-iodine laser medium  

SciTech Connect (OSTI)

A rate equation model for the loaded gain of a flowing chemical oxygen-iodine laser is described. The solution of the model is obtained for the loaded gain when the medium is stimulated by a multimode field. It is shown that optical saturation of the COIL medium is governed by three parameters: the ratio of the collision to Doppler linewidth measuring how much of the total linewidth is accessed; a saturation parameter measuring the field strength required to overcome medium quenching; and a cross-relaxation parameter measuring the ability of the velocity and hyper-fine relaxation to restore homogeneity to the transition. Criteria for the saturation character, homogeneous, inhomogeneous, or mixed, are established. This gain model is used to parametrically examine the sensitivity of the loaded gain and optical extraction efficiency to cavity pressure and to the uncertainty in the magnitude of the velocity cross-relaxation rates. It is shown, under single-mode operating conditions, that the extraction efficiency increases as the rate of velocity cross-relaxation increases and that the saturation behavior of the medium can be totally changed by only modes changes in the cavity operating conditions. The implication when interpreting experimental data and scaling from low to high power operation are briefly discussed and it is shown that interpreting test data without consideration of the factors presented here can lead to substantial error in estimating the power available from the flow.

Sedimentological control on saturation distribution in Arctic gas-hydrate-bearing sands  

Science Journals Connector (OSTI)

A mechanistic model is proposed to predict/explain hydrate saturation distribution in “converted free gas” hydrate reservoirs in sub-permafrost formations in the Arctic. This 1-D model assumes that a gas column accumulates and subsequently is converted to hydrate. The processes considered are the volume change during hydrate formation and consequent fluid phase transport within the column, the descent of the base of gas hydrate stability zone through the column, and sedimentological variations with depth. Crucially, the latter enable disconnection of the gas column during hydrate formation, which leads to substantial variation in hydrate saturation distribution. One form of variation observed in Arctic hydrate reservoirs is that zones of very low hydrate saturations are interspersed abruptly between zones of large hydrate saturations. The model was applied to data from Mount Elbert well, a gas hydrate stratigraphic test well drilled in the Milne Point area of the Alaska North Slope. The model is consistent with observations from the well log and interpretations of seismic anomalies in the area. The model also predicts that a considerable amount of fluid (of order one pore volume of gaseous and/or aqueous phases) must migrate within or into the gas column during hydrate formation. This paper offers the first explanatory model of its kind that addresses “converted free gas reservoirs” from a new angle: the effect of volume change during hydrate formation combined with capillary entry pressure variation versus depth.

This volatilized catalyst is returned to the gasifier where it uniformly contacts and condenses on the carbonaceous material. Also, the hot gaseous combustion products resulting from the combustion of the carbon in the ash along with excess air are introduced into the gasifier for providing heat energy used in the endothermic reaction. 1 fig.

Retardation and relativity: The case of a moving line charge  

Science Journals Connector (OSTI)

The electric and magnetic fields of a line charge of finite length uniformly moving along its axis are derived by using retarded field integrals and also by using transformationequations of the special relativitytheory. Both derivations yield the same field equations although the derivation methods are drastically different. In particular whereas transformationequations generally associated with Lorentz length contraction are crucial for the relativistic derivation Lorentz contraction is not used in the retarded field derivation. On the other hand although the retarded field derivation is based on the idea that retardation in the propagation of electromagnetic effects is a fundamental electromagnetic phenomenon the relativistic derivation does not take retardation into account. An examination of the two solutions indicates that the field equations obtained classically and relativistically are identical because retardation is implicit in relativistic transformations.

In this talk I show how to canonically quantize a massless scalar field in the background of a Schwarzschild black hole in Lema\\^itre coordinates and then present a simplified derivation of Hawking radiation based upon this procedure. The key result of quantization procedure is that the Hamiltonian of the system is explicitly time dependent and so problem is intrinsically non-static. From this it follows that, although a unitary time-development operator exists, it is not useful to talk about vacuum states; rather, one should focus attention on steady state phenomena such as the Hawking radiation. In order to clarify the approximations used to study this problem I begin by discussing the related problem of the massless scalar field theory calculated in the presence of a moving mirror.

The key result of quantization procedure is that the Hamiltonian of the system is explicitly time dependent and so problem is intrinsically non-static. From this it follows that, although a unitary time-development operator exists, it is not useful to talk about vacuum states; rather, one should focus attention on steady state phenomena such as the Hawking radiation. In order to clarify the approximations used to study this problem I begin by discussing the related problem of the massless scalar field theory calculated in the presence of a moving mirror.

Moving Mirrors, Black Holes, Hawking Radiation and All That  

SciTech Connect (OSTI)

In this talk I show how, in Lemaitre coordinates, one can canonically quantize a massless scalar field in the background of a Schwarzschild black hole and then show how this leads to a simplified derivation of Hawking radiation. The key result of the canonical quantization procedure is that the Hamiltonian of the system is explicitly time dependent, which immediately shows that the problem is intrinsically non-static and that, although a unitary time-development operator exists, it is not useful to talk about eigenstates. Rather, one should deal with the Heisenberg equations of motion and focus attention on steady state phenomena, such as the Hawking radiation. In order to clarify the procedure used to solve the Heisenberg equations I first discuss the related problem of the massless scalar field theory calculated in the presence of a moving mirror.

Moving Beyond NDE to Proactive Management of Materials Degradation  

SciTech Connect (OSTI)

There is growing interest in life extensions to enable longer term operation (LTO) for both existing nuclear power plants (NPPs) and proposed new NPPs. In order to justify an initial license extension for the 40-60 year period, new non-destructive examination (NDE) approaches have been developed and deployed by NPP operators in their Aging Management Programs (AMPs). However, to achieve the goals of even longer term operation, and specifically for the USA in looking at methodologies to support subsequent license renewal periods (i.e., 60-80 years, and beyond), it is necessary to understand the capabilities of current NDE methods to detect, monitor and trend degradation and hence enable timely implementation of appropriate corrective actions. This paper discusses insights from past experience, the state-of-the-art, and current activities in the move towards providing a capacity for proactive management of materials degradation (PMMD) to support NPP LTO.

Well log evaluation of natural gas hydrates  

SciTech Connect (OSTI)

Gas hydrates are crystalline substances composed of water and gas, in which a solid-water-lattice accommodates gas molecules in a cage-like structure. Gas hydrates are globally widespread in permafrost regions and beneath the sea in sediment of outer continental margins. While methane, propane, and other gases can be included in the clathrate structure, methane hydrates appear to be the most common in nature. The amount of methane sequestered in gas hydrates is probably enormous, but estimates are speculative and range over three orders of magnitude from about 100,000 to 270,000,000 trillion cubic feet. The amount of gas in the hydrate reservoirs of the world greedy exceeds the volume of known conventional gas reserves. Gas hydrates also represent a significant drilling and production hazard. A fundamental question linking gas hydrate resource and hazard issues is: What is the volume of gas hydrates and included gas within a given gas hydrate occurrence? Most published gas hydrate resource estimates have, of necessity, been made by broad extrapolation of only general knowledge of local geologic conditions. Gas volumes that may be attributed to gas hydrates are dependent on a number of reservoir parameters, including the areal extent ofthe gas-hydrate occurrence, reservoir thickness, hydrate number, reservoir porosity, and the degree of gas-hydrate saturation. Two of the most difficult reservoir parameters to determine are porosity and degreeof gas hydrate saturation. Well logs often serve as a source of porosity and hydrocarbon saturation data; however, well-log calculations within gas-hydrate-bearing intervals are subject to error. The primary reason for this difficulty is the lack of quantitative laboratory and field studies. The primary purpose of this paper is to review the response of well logs to the presence of gas hydrates.

Methane Hydrate Formation and Dissociation in a PartiallySaturated Core-Scale Sand Sample  

SciTech Connect (OSTI)

We performed a sequence of tests on a partiallywater-saturated sand sample contained in an x-ray transparent aluminumpressure vessel that is conducive to x-ray computed tomography (CT)observation. These tests were performed to gather data for estimation ofthermal properties of the sand/water/gas system and thesand/hydrate/water/gas systems, as well as data to evaluate the kineticnature of hydrate dissociation. The tests included mild thermalperturbations for the estimation of the thermal properties of thesand/water/gas system, hydrate formation, thermal perturbations withhydrate in the stability zone, hydrate dissociation through thermalstimulation, additional hydrate formation, and hydrate dissociationthrough depressurization with thermal stimulation. Density changesthroughout the sample were observed as a result of hydrate formation anddissociation, and these processes induced capillary pressure changes thataltered local water saturation.

Speed control of switched reluctance motors taking into account mutual inductances and magnetic saturation effects  

Science Journals Connector (OSTI)

This paper deals with the speed control of switched reluctance motor (SRM) drives taking into account the effects of the mutual inductances between two adjacent phases and the effects of the magnetic saturation of the core. To overcome the problems commonly associated with single-phase excitation, a nonlinear SRM model, which is suitable for two-phase excitation and which takes into account the effects of mutual inductances between two adjacent phases and the magnetic saturation effects, is considered in the design of the proposed controllers. A feedback linearization control scheme and a sliding mode control scheme are designed for this motor drive. The proposed controllers guarantee the convergence of the phase currents and the rotor speed of the motor to their desired values. Simulation results indicate that the proposed controllers work well and that they are robust to changes in the parameters of the system and to changes in the load torque.

Fractional-calculus model for temperature and pressure waves in fluid-saturated porous rocks  

Science Journals Connector (OSTI)

We study a fractional time derivative generalization of a previous Natale-Salusti model about nonlinear temperature and pressure waves, propagating in fluid-saturated porous rocks. Their analytic solutions, i.e., solitary shock waves characterized by a sharp front, are here generalized, introducing a formalism that allows memory mechanisms. In realistic wave propagation in porous media we must take into account spatial or temporal variability of permeability, diffusivity, and other coefficients due to the system “history.” Such a rock fracturing or fine particulate migration could affect the rock and its pores. We therefore take into account these phenomena by introducing a fractional time derivative to simulate a memory-conserving formalism. We also discuss this generalized model in relation to the theory of dynamic permeability and tortuosity in fluid-saturated porous media. In such a realistic model we obtain exact solutions of Burgers’ equation with time fractional derivatives in the inviscid case.

A CO/sub 2/ laser with a gaseous saturable absorber shows a variety of periodic self-pulsation (passive Q switching (PQS)), depending on the lasing conditions and the characteristics of the absorbing molecules. We present a novel rate-equation model that comprehensively describes the transient pulse structures of PQS in the CO/sub 2/ laser system. The numerical calculation based on the present model predicts that a chaotic PQS pulsation also is realized in a limited parameter region.

Bending waves due to a moving harmonic force.  

Science Journals Connector (OSTI)

In many structurally induced and flow?induced vibration problems the harmonic forcing function is not stationary but moves with a velocity V 0. The effect of the forcing function velocity V 0 upon the free vibrational wave?number characteristics of a membrane and a plate is analyzed. The Mach numberM is defined to be the ratio of the velocity V 0 to the wave speed of the bending waves. For the membrane the effect of the Mach number is to increase the wave number (shorter wavelength) ahead of the forcing function and to decrease the wave number (longer wavelength) behind it. At supersonic speeds no disturbances travel ahead of the forcing function and both wave numbers lead to trailing waves. These results are equivalent to the classical Doppler?shifted results. The results of the plate are more complex. The right and left traveling waves retain their basic properties with the magnitude of the wave number changing monotomically as a function of the Mach numberM. The near?field decaying disturbances also retain their basic properties but immediately obtain components that induce the decaying disturbances to become left traveling waves with decaying components. At Mach numbers greater than 2 these disturbances become pure waves trailing without any decaying factor. The importance of each of these components as a function of the Mach number is discussed.

Improved Moving Puncture Gauge Conditions for Compact Binary Evolutions  

E-Print Network [OSTI]

Robust gauge conditions are critically important to the stability and accuracy of numerical relativity (NR) simulations involving compact objects. Most of the NR community use the highly robust---though decade-old---moving-puncture (MP) gauge conditions for such simulations. It has been argued that in binary black hole (BBH) evolutions adopting this gauge, noise generated near adaptive-mesh-refinement (AMR) boundaries does not converge away cleanly with increasing resolution, severely limiting gravitational waveform accuracy at computationally feasible resolutions. We link this noise to a sharp (short-wavelength), initial outgoing gauge wave crossing into progressively lower resolution AMR grids, and present improvements to the standard MP gauge conditions that focus on stretching, smoothing, and more rapidly settling this outgoing wave. Our best gauge choice greatly reduces gravitational waveform noise during inspiral, yielding less fluctuation in convergence order and $\\sim 40%$ lower waveform phase and amplitude errors at typical resolutions. Noise in other physical quantities of interest is also reduced, and constraint violations drop by more than an order of magnitude. We expect these improvements will carry over to simulations of all types of compact binary systems, as well as other $N$+1 formulations of gravity for which MP-like gauge conditions can be chosen.

SciTech Connect (OSTI)

Innovations driven by the offshore industry's move into deeper, colder water and its continuing demand for solid operating research were highlighted in technical papers presented at the 26th Offshore Technology Conference held in Houston, May 2--5. For pipe line connecting and laying operations, there were discussions concerning: a diverless jumper connector system for two 12-in. lines to be carried out in 2,130 ft water depth; what's believed to be the first near vertical, deepwater, J-lay project, conducted in 2,860 ft of water; first year results from operation of a prototype subsea, ROV-controlled, lightweight pipe line trencher for flexible lines. In operating research, scientists reported on new laboratory test apparatus and results designed to investigate wax deposition and gel strength of waxy live crude oils. Operators, perhaps for the first time, have data on the impact of oil bubble point, flowrate and paraffin inhibitor on wax deposition and the impact of oil bubble point and pipe size on the gel strength of waxy crudes, including both stock tank oils and live oils.

Heat-driven acoustic cooling engine having no moving parts  

DOE Patents [OSTI]

A heat-driven acoustic cooling engine having no moving parts receives heat from a heat source. The acoustic cooling engine comprises an elongated resonant pressure vessel having first and second ends. A compressible fluid having a substantial thermal expansion coefficient and capable of supporting an acoustic standing wave is contained in the resonant pressure vessel. The heat source supplies heat to the first end of the vessel. A first heat exchanger in the vessel is spaced-apart from the first end and receives heat from the first end. A first thermodynamic element is adjacent to the first heat exchanger and converts some of the heat transmitted by the first heat exchanger into acoustic power. A second thermodynamic element has a first end located spaced-apart from the first thermodynamic element and a second end farther away from the first thermodynamic element than is its first end. The first end of the second thermodynamic element heats while its second end cools as a consequence of the acoustic power. A second heat exchanger is adjacent to and between the first and second thermodynamic elements. A heat sink outside of the vessel is thermally coupled to and receives heat from the second heat exchanger. The resonant pressure vessel can include a housing less than one-fourth wavelength in length coupled to a reservoir. The housing can include a reduced diameter portion communicating with the reservoir.

Casimir Friction Force and Energy Dissipation for Moving Harmonic Oscillators  

E-Print Network [OSTI]

The Casimir friction problem for a pair of dielectric particles in relative motion is analyzed, utilizing a microscopic model in which we start from statistical mechanics for harmonically oscillating particles at finite temperature moving nonrelativistically with constant velocity. The use of statistical mechanics in this context has in our opinion some definite advantages, in comparison with the more conventional quantum electrodynamic description of media that involves the use of a refractive index. The statistical-mechanical description is physical and direct, and the oscillator model, in spite of its simplicity, is nevertheless able to elucidate the essentials of the Casimir friction. As is known, there are diverging opinions about this kind of friction in the literature. Our treatment elaborates upon, and extends, an earlier theory presented by us back in 1992. There we found a finite friction force at any finite temperature, whereas at zero temperature the model led to a zero force. As an additional development in the present paper we evaluate the energy dissipation making use of an exponential cutoff truncating the relative motion of the oscillators. For the dissipation we also establish a general expression that is not limited to the simple oscillator model.

One of the facts of life discovered in the 20th century is that the speed of light (300,000 kilometers per second) is the ultimate speed limit. As you add energy to the electron, it will go faster, but as you get it to go close to the speed of light, you find that you have to add even more energy just to bump it a bit faster.

A Study of the Dielectric Properties of Dry and Saturated Green River Oil Shale  

SciTech Connect (OSTI)

We measured dielectric permittivity of dry and fluid-saturated Green River oil shale samples over a frequency range of 1 MHz to 1.8 GHz. Dry sample measurements were carried out between room temperature and 146 C, saturated sample measurements were carried out at room temperature. Samples obtained from the Green River formation of Wyoming and from the Anvil Points Mine in Colorado were cored both parallel and perpendicular to layering. The samples, which all had organic richness in the range of 10-45 gal/ton, showed small variations between samples and a relatively small level of anisotropy of the dielectric properties when dry. The real and imaginary part of the relative dielectric permittivity of dry rock was nearly constant over the frequency range observed, with low values for the imaginary part (loss factor). Saturation with de-ionized water and brine greatly increased the values of the real and imaginary parts of the relative permittivity, especially at the lower frequencies. Temperature effects were relatively small, with initial increases in permittivity to about 60 C, followed by slight decreases in permittivity that diminished as temperature increased. Implications of these observations for the in situ electromagnetic, or radio frequency (RF) heating of oil shale to produce oil and gas are discussed.

The text of the basic agreement , Annex VI and all amendments, are appended to the report. In addition to a chronicle of events detailing progress under Annex VI, this report also inlcudes a discussion of future work to be performed in the areas of subsidence accompanying the extraction of oil and interwell oil saturation measurement. A meeting was held in Bartlesville May 10 and 11 to formulate plans in this area.

Saturation and Dynamic Range of Microchannel Plate-Based X-Ray Imagers  

SciTech Connect (OSTI)

This paper describes recent advances in Monte Carlo simulations of microchannel plate (MCP)–based x-ray detectors, a continuation of ongoing work in this area. A Monte Carlo simulation model has been developed over the past several years by National Security Technologies, LLC (NSTec). The model simulates the secondary electron emission process in an MCP pore and includes the effects of gain saturation. In this work we focus on MCP gain saturation and dynamic range. We have performed modeling and experimental characterizations of L/D = 46, 10-micron diameter, MCP-based detectors. The detectors are typically operated by applying a subnanosecond voltage pulse, which gates the detector on. Agreement between the simulations and experiment is very good for a variety of voltage pulse waveforms ranging in width from 150 to 300 ps. The results indicate that such an MCP begins to show nonlinear gain around 5 × 10^4 electrons per pore and hard saturation around 105 electrons per pore. The simulations show a difference in MCP sensitivity vs voltage for high flux of photons producing large numbers of photoelectrons on a subpicosecond timescale. Simulations and experiments both indicate an MCP dynamic range of 1 to 10,000, and the dynamic range depends on how the voltage is applied.

A three-dimensional laboratory steam injection model allowing in situ saturation measurements  

SciTech Connect (OSTI)

The CT imaging technique together with temperature and pressure measurements were used to follow the steam propagation during steam and steam foam injection experiments in a three dimensional laboratory steam injection model. The advantages and disadvantages of different geometries were examined to find out which could best represent radial and gravity override flows and also fit the dimensions of the scanning field of the CT scanner. During experiments, steam was injected continuously at a constant rate into the water saturated model and CT scans were taken at six different cross sections of the model. Pressure and temperature data were collected with time at three different levels in the model. During steam injection experiments, the saturations obtained by CT matched well with the temperature data. That is, the steam override as observed by temperature data was also clearly seen on the CT pictures. During the runs where foam was present, the saturation distributions obtained from CT pictures showed a piston like displacement. However, the temperature distributions were different depending on the type of steam foam process used. The results clearly show that the pressure/temperature data alone are not sufficient to study steam foam in the presence of non-condensible gas.

High-temperature superconducting magnet for use in saturated core FCL  

Science Journals Connector (OSTI)

A HTS magnet system used in a saturated core Fault Current Limiter (FCL) device is described. The superconducting magnet, operating in DC mode, is used in such FCL design for saturating the magnetic core and maintaining low device impedance under nominal conditions. The unique design of the FCL poses constrains on the DC HTS magnet. A model which meets all the necessary special requirements have been realized in a compact magnet design that is optimized for its electrical characteristics while minimizing its mass and volume. The coil, made of Bi-2223 tapes, has 50000 Ampere-turns required to maintain the core in a saturated state at nominal current in the limiting circuit. Unique, nonmagnetic cryostat made of Delrin was used. Cooling of the coil has been realized by two cold heads: one double-stage head that provides a cooling power of 6 W at 20 K and a single-stage head with a cooling capability of 40W at 70 K. This magnetic system has been successfully integrated and tested in a 120 kVA FCL model. The design, characteristics and tests of this magnetic system are described.

Scale-dependent gas hydrate saturation estimates in sand reservoirs in the Ulleung Basin, East Sea of Korea  

Science Journals Connector (OSTI)

Through the use of 2-D and 3-D seismic data, several gas hydrate prospects were identified in the Ulleung Basin, East Sea of Korea and thirteen drill sites were established and logging-while-drilling (LWD) data were acquired from each site in 2010. Sites UBGH2–6 and UBGH2–10 were selected to test a series of high amplitude seismic reflections, possibly from sand reservoirs. LWD logs from the UBGH2–6 well indicate that there are three significant sand reservoirs with varying thickness. Two upper sand reservoirs are water saturated and the lower thinly bedded sand reservoir contains gas hydrate with an average saturation of 13%, as estimated from the P-wave velocity. The well logs at the UBGH2–6 well clearly demonstrated the effect of scale-dependency on gas hydrate saturation estimates. Gas hydrate saturations estimated from the high resolution LWD acquired ring resistivity (vertical resolution of about 5–8 cm) reaches about 90% with an average saturation of 28%, whereas gas hydrate saturations estimated from the low resolution A40L resistivity (vertical resolution of about 120 cm) reaches about 25% with an average saturation of 11%. However, in the UBGH2–10 well, gas hydrate occupies a 5-m thick sand reservoir near 135 mbsf with a maximum saturation of about 60%. In the UBGH2–10 well, the average and a maximum saturation estimated from various well logging tools are comparable, because the bed thickness is larger than the vertical resolution of the various logging tools. High resolution wireline log data further document the role of scale-dependency on gas hydrate calculations.

Sinusoidal self-modulation in the output of a CO/sub 2/ laser with an intracavity saturable absorber  

SciTech Connect (OSTI)

Conditions under which a sinusoidally modulated laser output occurs in a CO/sub 2/ laser with a saturable absorber were studied experimentally and theoretically for a wide range of laser operating parameters. A novel type of transition between stability and instability appears in the high-pressure range of the saturable absorber. Through the rate-equation analysis based on the three-level (the gain medium): two-level (the loss medium) model, the observed pulse shapes and the features of transitions in the phase diagram are reproducible. The conditions of saturable absorbers to obtain the sinusoidal are clarified from the analysis.

Importance of Low Permeability Natural Gas Reservoirs (released in AEO2010)  

Reports and Publications (EIA)

Production from low-permeability reservoirs, including shale gas and tight gas, has become a major source of domestic natural gas supply. In 2008, low-permeability reservoirs accounted for about 40% of natural gas production and about 35% of natural gas consumption in the United States. Permeability is a measure of the rate at which liquids and gases can move through rock. Low-permeability natural gas reservoirs encompass the shale, sandstone, and carbonate formations whose natural permeability is roughly 0.1 millidarcies or below. (Permeability is measured in darcies.)

OFFICE OF SCIENCE AND TECHNOLOGY AND INTERNATIONAL, NATURAL BARRIERS THRUST OVERVIEW  

SciTech Connect (OSTI)

The Natural Barriers Thrust supports scientific studies of the natural system at the proposed repository site of Yucca Mountain. It stresses the realistic representation of the natural system with respect to processes and parameters, by means of laboratory, field, and modeling studies. It has the objectives to demonstrate that the natural barriers can make large contributions to repository performance, supporting the multiple-barrier concept for geological disposal of high-level radioactive waste; and to reduce the overall cost of repository development by elimination of unnecessary engineered components, given the demonstrated natural barriers performance. In this overview we enumerate the research projects within the Natural Barriers Thrust grouped under five elements: (1) Drift Seepage, (2) In-drift Environment, (3) Drift Shadow, (4) Unsaturated Zone Flow and Transport, and (5) Saturated Zone Flow and Transport. The long-term strategic plan of the Natural Barriers Thrust and some key results are also briefly described.

Thermalization, Isotropization and Elliptic Flow from Nonequilibrium Initial Conditions with a Saturation Scale  

E-Print Network [OSTI]

In this article we report on our results about the computation of the elliptic flow of the quark-gluon-plasma produced in relativistic heavy ion collisions, simulating the expansion of the fireball by solving the relativistic Boltzmann equation for the parton distribution function tuned at a fixed shear viscosity to entropy density ratio $\\eta/s$. Our main goal is to put emphasis on the role of a saturation scale in the initial gluon spectrum, which makes the initial distribution far from a thermalized one. We find that the presence of the saturation scale reduces the efficiency in building-up the elliptic flow, even if the thermalization process is quite fast $\\tau_{therm} \\approx 0.8 \\,\\rm fm/c$ and the pressure isotropization even faster $\\tau_{isotr} \\approx 0.3 \\,\\rm fm/c$. The impact of the non-equilibrium implied by the saturation scale manifests for non-central collisions and can modify the estimate of the viscosity respect to the assumption of full thermalization in $p_T$-space. We find that the estimate of $\\eta/s$ is modified from $\\eta/s \\approx 2/4\\pi$ to $\\eta/s \\approx 1/4\\pi$ at RHIC and from $\\eta/s \\approx 3/4\\pi$ to $\\eta/s \\approx 2/4\\pi$ at LHC. We complete our investigation by a study of the thermalization and isotropization times of the fireball for different initial conditions and values of $\\eta/s$ showing how the latter affects both isotropization and thermalization. Lastly, we have seen that the range of values explored by the phase-space distribution function $f$ is such that at $p_T<0.5\\, \\rm GeV$ the inner part of the fireball stays with occupation number significantly larger than unity despite the fast longitudinal expansion, which might suggest the possibility of the formation of a transient Bose-Einstein Condensate.

SATURATION OF THE MAGNETO-ROTATIONAL INSTABILITY IN STRONGLY RADIATION-DOMINATED ACCRETION DISKS  

SciTech Connect (OSTI)

The saturation level of the magneto-rotational instability (MRI) in a strongly radiation-dominated accretion disk is studied using a new Godunov radiation MHD code in the unstratified shearing box approximation. Since vertical gravity is neglected in this work, our focus is on how the MRI saturates in the optically thick mid-plane of the disk. We confirm that turbulence generated by the MRI is very compressible in the radiation-dominated regime, as found by previous calculations using the flux-limited diffusion approximation. We also find little difference in the saturation properties in calculations that use a larger horizontal domain (up to four times the vertical scale height in the radial direction). However, in strongly radiation pressure dominated disks (one in which the radiation energy density reaches {approx}1% of the rest mass energy density of the gas), we find that Maxwell stress from the MRI turbulence is larger than the value produced when radiation pressure is replaced with the same amount of gas pressure. At the same time, the ratio between Maxwell stress and Reynolds stress is increased by almost a factor of eight compared with the gas pressure dominated case. We suggest that this effect is caused by radiation drag, which acts like bulk viscosity and changes the effective magnetic Prandtl number of the fluid. Radiation viscosity significantly exceeds both the microscopic plasma viscosity and resistivity, ensuring that radiation-dominated systems occupy the high magnetic Prandtl number regime. Nevertheless, we find that radiative shear viscosity is negligible compared to the Maxwell stress and Reynolds stress in the flow. This may have important implications for the structure of radiation-dominated accretion disks.

Residual oil saturation determination. Wilmington micellar-polymer project. Final report  

SciTech Connect (OSTI)

The City of Long Beach, California conducted a program to obtain residual oil saturation (ROS) data in the HX/sub a/ Sand, Fault Block VB, Wilmington Field. This program utilized many complementary techniques for determining the ROS in a watered-out unconsolidated sand, typical of many reservoirs in the California Coastal Province. This program was to be performed in two stages. The first, Phase 1, was intended to determine the ROS in an area which had been flooded out during the course of a peripheral waterflood and to make a comparative analysis of current methods for determination of in-situ oil in place. The second stage, Phase 2 of the ROS program, was intended to measure the ROS after tertiary recovery by a micellar-polymer flood; however, the second phase was not carried out for lack of funds. This report describes the diagnostic tools and techniques which have been used to establish ROS. It then presents a comparative analysis of the results obtained using the different techniques. Inasmuch as the determination of in-situ oil saturation is directly dependent upon the in-situ value for porosity, it is required that the pore volume as a fraction of the reservoir rock be determined before the residual oil equation can be solved. Because of this, much of the study necessarily was concerned with measurement of porosity of the unconsolidated sand. The method finally used to obtain a very good core recovery in this highly unconsolidated sand is described. Present oil saturation and oil content of the HX/sub a/ sand in the Pilot is now believed to be better defined. This conclusion is supported by results obtained for electrical log analysis, analysis of full sized native state cores run under stress conditions, plug core analysis under stressed conditions and a Single-Well Tracer Survey. 15 references, 18 figures, 16 tables.

Period-doubling bifurcation and chaotic passive Q switching which are predicted on the basis of the recently proposed model of the laser system have been observed by use of a CO/sub 2/ laser with a formic acid absorber. This is the first experimental evidence of deterministic chaos in a single-mode laser system with a saturable absorber.

A saturated-absorption experiment is used to measure the effects of velocity-changing collisions between Kr* metastable atoms (4p55s[32]2) and He and Ar perturbers. Comparison between experimental profiles and profiles calculated assuming hard-sphere collisions between Kr* and perturber atoms confirms the calculations of Borenstein and Lamb concerning the change of velocity associated with a collision. Furthermore it is found that the rate of velocity-changing collisions is consistent with the predictions of kinetic theory.

Continuous-time random-walk model of transport in variably saturated heterogeneous porous media  

Science Journals Connector (OSTI)

We propose a unified physical framework for transport in variably saturated porous media. This approach allows fluid flow and solute migration to be treated as ensemble averages of fluid and solute particles, respectively. We consider the cases of homogeneous and heterogeneous porous materials. Within a fractal mobile-immobile continuous time random-walk framework, the heterogeneity will be characterized by algebraically decaying particle retention times. We derive the corresponding (nonlinear) continuum-limit partial differential equations and we compare their solutions to Monte Carlo simulation results. The proposed methodology is fairly general and can be used to track fluid and solutes particles trajectories for a variety of initial and boundary conditions.

Dual structure of saturated absorption resonance at an open atomic transition  

SciTech Connect (OSTI)

Experiments on open transitions of the D{sub 1} line of alkali metals (Cs and Rb isotopes) reveal the dual structure of saturated absorption resonance in the signal of a high-intensity optical wave in the presence of a low-intensity counterpropagating wave. Theoretical analysis shows that the observed shape of the resonance is associated with the openness of the atomic transition as well as with the Doppler effect for atoms in a gas. The results are of general physical significance for nonlinear spectroscopy and can also find application in metrology (frequency and time standards on open transitions).
