Gravitational instability of slowly rotating isothermal spheres  

E-Print Network (OSTI)

We discuss the statistical mechanics of rotating self-gravitating systems by allowing properly for the conservation of angular momentum. We study analytically the case of slowly rotating isothermal spheres by expanding the solutions of the Boltzmann-Poisson equation in a series of Legendre polynomials, adapting the procedure introduced by Chandrasekhar (1933) for distorted polytropes. We show how the classical spiral of Lynden-Bell & Wood (1967) in the temperature-energy plane is deformed by rotation. We find that gravitational instability occurs sooner in the microcanonical ensemble and later in the canonical ensemble. According to standard turning point arguments, the onset of the collapse coincides with the minimum energy or minimum temperature state in the series of equilibria. Interestingly, it happens to be close to the point of maximum flattening. We determine analytically the generalization of the singular isothermal solution to the case of a slowly rotating configuration. We also consider slowly ...

Plasma Wave Reflection in Slowly Varying Media  

Science Journals Connector (OSTI)

Two mathematical formalisms are presented to describe wave reflection in a slowly varying spatially inhomogeneous thermal plasma described by the Vlasov equation. It is found that the transmitted wave which is the Wentzel?Kramer?Brillouin solution and the reflected wave can be expressed in terms of the local dielectric properties of the medium. In a numerical example it is shown that the intrinsic thermal properties of the plasma can supply reflection mechanisms that compete with the reflection coefficient predicted when the plasma is described by fluid equations.

How plants grow toward light  

NLE Websites -- All DOE Office Websites (Extended Search)

How plants grow toward light How plants grow toward light Name: schwobtj Location: N/A Country: N/A Date: N/A Question: When a seed is planted below the surface of the ground, how does it "know" to grow toward the light? Replies: Plants don't know where the light is, they do respond to gravity. Since light is usually up, a plant seed grows up and finds light enough to keep things going. Psych One way that plants below ground can tell which way is up is with the use of STATOLITHS. Statoliths are dense pieces of material that settle to the bottom of a STATOCYST. In plants, pieces of starch or another material denser than water will settle to the bottom of the cell. Somehow the plant cell determines on what side the statolith has fallen, and then somehow relays a message (probably a chemical) that tells the bottom cells to grow faster than the top cells, therefore causing upward growth. There is still quite a lot of mystery in there to be discovered. I got this explanation from BIOLOGY by Neil Campbell. This is similar to the way in which plants use chemical signals to help them grow towards light.

Growing tissue in the lab  

NLE Websites -- All DOE Office Websites (Extended Search)

tissue in the lab tissue in the lab Name: mike s Location: N/A Country: N/A Date: N/A Question: How do Scientists grow new tissue cells in the lab? Replies: I'm not quite sure what you mean by "new" cells. Several kinds of cell growing are done. One way is to break an organ or tissue apart into its individual cells and grow them in a medium of nutrients, controlled temperature, humidity, and carbon dioxide/oxygen. This is called "primary culture" because the cells come right out of an organism. Another method is to create an "immortal cell line". This is a type of cell isolated from a cancerous tumor, or a non-tumor cell which is infected with a cancer gene after it's isolated. Being cancerous, these cells grow forever in a dish, with the appropriate nutrients etc as long as you remove cells from time to time to prevent overcrowding. These cells can be frozen at about -100F forever and rethawed when needed. There is a library of frozen cells, thousands of types, and a catalog. Scientists can order what they need any time! Finally, you can make specific mutant cell lines by starting as above with an immortal cell, and inserting a specific gene (or deleting one) permanently from the DNA of the cell to change almost any property you want. So there it is.

Extended solution space for Chern-Simons gravity: The slowly rotating Kerr black hole  

SciTech Connect

In the Einstein-Cartan formulation, an iterative procedure to find solutions in nondynamical Chern-Simons gravity in vacuum is proposed. The iterations, in powers of a small parameter {beta} which codifies the Chern-Simons coupling, start from an arbitrary torsionless solution of Einstein equations. With Schwarzschild as the zeroth-order choice, we derive a second-order differential equation for the O({beta}) corrections to the metric, for an arbitrary zeroth-order embedding parameter. In particular, the slowly rotating Kerr metric is an O({beta}) solution in either the canonical or the axial embeddings.

The slowly varying density approximation for the surface tension and surface energy of  

Science Journals Connector (OSTI)

We present a detailed study of the validity of the slowly varying density approximation to calculate the surface tension and the surface energy of Lennard-Jones fluids. To do so, we consider three explicit analytical expressions for the radial distribution function of the liquid phase, including one proposed by our research group, together with very accurate expressions for the liquid and vapour densities, also proposed by ourselves. The calculation of the surface tension from the direct correlation function using the PercusYevick and the hypernetted-chain approximations is also considered. Finally, our results are compared with those obtained by other authors by computer simulation, and also with those estimated via the general expressions (i.e., not in the ambit of the approximation studied here). We demonstrate that although the slowly varying density approximation is in good agreement with more complex expressions near the critical point, it is not adequate to calculate the surface energy and the surface tension of Lennard-Jones fluids at every temperature.

Slowly Rotating Anisotropic Neutron Stars in General Relativity and Scalar-Tensor Theory  

E-Print Network (OSTI)

Some models (such as the Skyrme model, a low-energy effective field theory for QCD) suggest that the high-density matter prevailing in neutron star interiors may be significantly anisotropic. Anisotropy is known to affect the bulk properties of nonrotating neutron stars in General Relativity. In this paper we study the effects of anisotropy on slowly rotating stars in General Relativity. We also consider one of the most popular extensions of Einstein's theory, namely scalar-tensor theories allowing for spontaneous scalarization (a phase transition similar to spontaneous magnetization in ferromagnetic materials). Anisotropy affects the moment of inertia of neutron stars (a quantity that could potentially be measured in binary pulsar systems) in both theories. We find that the effects of scalarization increase (decrease) when the tangential pressure is bigger (smaller) than the radial pressure, and we present a simple criterion to determine the onset of scalarization by linearizing the scalar-field equation.

Excitation of solitons by an external resonant wave with a slowly varying phase velocity  

SciTech Connect

A novel mechanism is proposed for the excitation of solitons in nonlinear dispersive media. The mechanism employs an external pumping wave with a varying phase velocity, which provides a continuous resonant excitation of a nonlinear wave in the medium. Two different schemes of a continuous resonant growth (continuous phase-locking) of the induced nonlinear wave are suggested. The first of them requires a definite time dependence of the pumping wave phase velocity and is relatively sensitive to the initial wave phase. The second employs the dynamic autoresonance effect and is insensitive to the exact time dependence of the pumping wave phase velocity. It is demonstrated analytically and numerically, for a particular example of a driven Korteweg-de Vries (KdV) equation with periodic boundary conditions, that as the nonlinear wave grows, it transforms into a soliton, which continues growing and accelerating adiabatically. A fully nonlinear perturbation theory is developed for the driven KdV equation to follow the growing wave into the strongly nonlinear regime and describe the soliton formation.

Slowly rotating Kerr black hole as a solution of Einstein-Cartan gravity extended by a Chern-Simons term  

E-Print Network (OSTI)

We consider the nondynamical Chern-Simons (CS) modification to General Relativity (GR) in the framework of the Einstein-Cartan formulation, as providing a way to incorporate a slowly rotating Kerr black hole in the space of solutions. Our proposal lies on considering the CS term as a source of torsion and on an iterative procedure to look for vacuum solutions of the system, by expanding the tetrad, the connection and the embedding parameter, in powers of a dimensionless small parameter $\\beta$ which codifies the CS coupling. Starting from a torsionless zeroth-order vacuum solution we derive the second-order differential equation for the $\\mathcal{O}(\\beta)$ corrections to the metric, for an arbitrary embedding parameter. Furthermore we can show that the slowly rotating Kerr metric is an $\\mathcal{O}(\\beta)$ solution of the system either in the canonical or the axial embeddings.

Quantum field theory on a growing lattice  

E-Print Network (OSTI)

We construct the classical and canonically quantized theories of a massless scalar field on a background lattice in which the number of points--and hence the number of modes--may grow in time. To obtain a well-defined theory certain restrictions must be imposed on the lattice. Growth-induced particle creation is studied in a two-dimensional example. The results suggest that local mode birth of this sort injects too much energy into the vacuum to be a viable model of cosmological mode birth.

Fast-growing willow shrub named `Canastota`  

DOE Patents (OSTI)

A distinct male cultivar of Salix sachalinensis.times.S. miyabeana named `Canastota`, characterized by rapid stem growth producing greater than 2.7-fold more woody biomass than its female parent (Salix sachalinensis `SX61`), 28% greater woody biomass yield than its male parent (Salix miyabeana `SX64`), and 20% greater woody biomass yield than a standard production cultivar, Salix dasyclados `SV1` when grown in the same field for the same length of time (two growing seasons after coppice) in Tully, N.Y. `Canastota` can be planted from dormant stem cuttings, produces multiple stems after coppice, and the stem biomass can be harvested when the plant is dormant. In the spring following harvest, the plant will re-sprout very vigorously, producing new stems that can be harvested after two to four years of growth. This harvest cycle can be repeated several times. `Canastota` displays a low incidence of rust disease or damage by willow sawfly.

Turkey opens electricity markets as demand grows  

SciTech Connect

Turkey's growing power market has attracted investors and project developers for over a decade, yet their plans have been dashed by unexpected political or financial crises or, worse, obstructed by a lengthy bureaucratic approval process. Now, with a more transparent retail electricity market, government regulators and investors are bullish on Turkey. Is Turkey ready to turn the power on? This report closely examine Turkey's plans to create a power infrastructure capable of providing the reliable electricity supplies necessary for sustained economic growth. It was compiled with on-the-ground research and extensive interview with key industrial and political figures. Today, hard coal and lignite account for 21% of Turkey's electricity generation and gas-fired plants account for 50%. The Alfin Elbistan-B lignite-fired plant has attracted criticism for its lack of desulfurization units and ash dam facilities that have tarnished the industry's image. A 1,100 MW hard-coal fired plant using supercritical technology is under construction. 9 figs., 1 tab.

On carbon footprints and growing energy use  

SciTech Connect

Could fractional reductions in the carbon footprint of a growing organization lead to a corresponding real reduction in atmospheric CO{sub 2} emissions in the next ten years? Curtis M. Oldenburg, head of the Geologic Carbon Sequestration Program of LBNLs Earth Sciences Division, considers his own organization's carbon footprint and answers this critical question? In addressing the problem of energy-related greenhouse gas (GHG) emissions and climate change, it is essential that we understand which activities are producing GHGs and the scale of emission for each activity, so that reduction efforts can be efficiently targeted. The GHG emissions to the atmosphere of an individual or group are referred to as the carbon footprint. This terminology is entirely appropriate, because 85% of the global marketed energy supply comes from carbon-rich fossil fuel sources whose combustion produces CO{sub 2}, the main GHG causing global climate change. Furthermore, the direct relation between CO2 emissions and fossil fuels as they are used today makes energy consumption a useful proxy for carbon footprint. It would seem to be a simple matter to reduce energy consumption across the board, both individually and collectively, to help reduce our carbon footprints and therefore solve the energyclimate crisis. But just how much can we reduce carbon footprints when broader forces, such as growth in energy use, cause the total footprint to simultaneously expand? In this feature, I present a calculation of the carbon footprint of the Earth Sciences Division (ESD), the division in which I work at Lawrence Berkeley National Laboratory (LBNL), and discuss the potential for reducing this carbon footprint. It will be apparent that in terms of potential future carbon footprint reductions under projections of expected growth, ESD may be thought of as a microcosm of the situation of the world as a whole, in which alternatives to the business-as-usual use of fossil fuels are needed if absolute GHG emission reductions are to be achieved.

The motion of a neutral particle in the vicinity of a slowly rotating black hole in the Horava-Lifshitz theory of gravity and 3+1 dimensional topological Lifshitz black hole is investigated. Geodesics for radial motion of the particles are also plotted. Some different cases of the orbital motion of the particle are discussed where maximum and minimum values of the effective potential are calculated. Further the Ba\\~{n}ados, Silk and West (BSW) mechanism is studied for these black holes. It is shown that the centre-of-mass energy (CME) of two colliding uncharged particles at the horizon of these black holes remains finite. Thus the BSW effect cannot be seen in these cases.

Growing network model for community with group structure  

Science Journals Connector (OSTI)

We propose a growing network model for a community with a group structure. The community consists of individual members and groups, gatherings of members. The community grows as a new member is introduced by an existing member at each time step. The new member then creates a new group or joins one of the groups of the introducer. We investigate the emerging community structure analytically and numerically. The group size distribution shows a power-law distribution for a variety of growth rules, while the activity distribution follows an exponential or a power law depending on the details of the growth rule. We also present an analysis of empirical data from online communities the Groups in http://www.yahoo.com and the Cafe in http://www.daum.net, which show a power-law distribution for a wide range of group sizes.

Renewable energy has political support, room to grow  

SciTech Connect

Renewable energy sources enjoy growing political support and have plenty of room to grow in the worldwide energy mix. And grow they will, according to most projections. The US Energy Information Administration`s (EIA`s) International Energy Outlook 1997 says consumption of hydroelectricity and other renewables will increase by 56% during 1995--2015. The renewable share of the total energy mix will remain at about current levels, however. The EIA projection includes only renewable fuels used in the generation of electricity. It therefore excludes most biomass energy. Despite the importance of biomass energy, data on consumption of it are sparse. IEA estimates that in the industrialized world, the biomass share of primary energy consumption amounts to 3.5%. Also excluded from EIA`s projection because of insufficiency of data are dispersed renewables, a category that includes energy consumed at the site of production, such as solar panels used for water heating. This paper discusses regional trends, North American activity, Western Europe, Asian developments, and the rest of the world.

Growing drift-cyclotron modes in the hot solar atmosphere  

E-Print Network (OSTI)

Well-known analytical results dealing with ion cyclotron and drift waves and which follow from the kinetic theory are used and the dispersion equation, which describes coupled two modes, is solved numerically. The numerical results obtained by using the values for the plasma density, magnetic field and temperature applicable to the solar corona clearly show the coupling and the instability (growing) of the two modes. The coupling happens at very short wavelengths, that are of the order of the ion gyro radius, and for characteristic scale lengths of the equilibrium density that are altitude dependent and may become of the order of only a few meters. The demonstrated instability of the two coupled modes (driven by the equilibrium density gradient) is obtained by using a rigorous kinetic theory model and for realistic parameter values. The physical mechanism which is behind the coupling is simple and is expected to take place throughout the solar atmosphere and the solar wind which contain a variety of very elongated density structures of various sizes. The mode grows on account of the density gradient, it is essentially an ion mode, and its further dissipation should result in an increased ion heating.

Fast-growing willow shrub named `Tully Champion`  

DOE Patents (OSTI)

A distinct female cultivar of Salix viminalis.times.S. miyabeana named `Tully Champion`, characterized by rapid stem growth producing greater than 25% more woody biomass than two current production clones (Salix dasyclados `SV1` and Salix miyabeana `SX64`), more than 2.5-fold greater biomass than one of its parents (Salix miyabeana `SX67`), and nearly 3-fold more biomass than another production clone (Salix sacchalinensis, `SX61`) when grown in the same field for the same length of time (two growing seasons after coppice) in Tully, N.Y. `Tully Champion` can be planted from dormant stem cuttings, produces multiple stems after coppice, and the stem biomass can be harvested when the plant is dormant. In the spring following harvest, the plant will re-sprout very vigorously, producing new stems that can be harvested repeatedly after two to four years of growth. `Tully Champion` displays a low incidence of rust disease and is not damaged by potato leafhoppers.

Mushroom growing project at the Los Humeros, Mexico geothermal field  

SciTech Connect

There are several projects of direct (non-electrical) use of geothermal energy in Mexico. Personnel of the Comision Federal de Electricidad (CFE) have experience in various of these projects, like drying of timber and fruits, space heating, food processing, etc. Taking this in consideration, CFE built the Los Humeros mushroom plant using for heat source the geothermal steam from Well H-1. The main purpose of the project was to take advantage of residual geothermal energy in a food production operation and to develop the appropriate technology. In 1992, existing installations were renovated, preparing appropriate areas for pasteurization, inoculation and production. The mushroom Pleurotus ostreatus var. florida and columbinus was used. A year later, CFE proposed the construction of improved facilities for growing edible mushrooms. New materials and equipment, as well as different operation conditions, were proposed on the basis of the experience gained in the initial project. The construction and renovation activities were completed in 1994.

Soviet Union oil sector outlook grows bleaker still  

SciTech Connect

This paper reports on the outlook for the U.S.S.R's oil sector which grows increasingly bleak and with it prospects for the Soviet economy. Plunging Soviet oil production and exports have analysts revising near term oil price outlooks, referring to the Soviet oil sector's self-destructing and Soviet oil production in a freefall. County NatWest, Washington, citing likely drops in Soviet oil production and exports (OGJ, Aug. 5, p. 16), has jumped its projected second half spot price for West Texas intermediate crude by about $2 to $22-23/bbl. Smith Barney, New York, forecasts WTI postings at $24-25/bbl this winter, largely because of seasonally strong world oil demand and the continued collapse in Soviet oil production. It estimates the call on oil from the Organization of Petroleum Exporting Countries at more than 25 million b/d in first quarter 1992. That would be the highest level of demand for OPEC oil since 1980, Smith Barney noted.

Stress-driven instability in growing multilayer films  

Science Journals Connector (OSTI)

We investigate the stress-driven morphological instability of epitaxially growing multilayer films, which are coherent and dislocation-free. We construct a direct elastic analysis, from which we determine the elastic state of the system recursively in terms of that of the old states of the buried layers. In turn, we use the result for the elastic state to derive the morphological evolution equation of surface profile to first order of perturbations, with the solution explicitly expressed by the growth conditions and material parameters of all the deposited layers. We apply these results to two kinds of multilayer structures. One is the alternating tensile/compressive multilayer structure, for which we determine the effective stability properties, including the effect of varying surface mobility in different layers, its interplay with the global misfit of the multilayer film, and the influence of asymmetric structure of compressive and tensile layers on the system stability. The nature of the asymmetry properties found in stability diagrams is in agreement with experimental observations. The other multilayer structure that we study is one composed of stacked strained/spacer layers. We also calculate the kinetic critical thickness for the onset of morphological instability and obtain its reduction and saturation as the number of deposited layers increases, which is consistent with recent experimental results. Compared to the single-layer film growth, the behavior of kinetic critical thickness shows deviations for upper strained layers.

Biotechnology and genetic optimization of fast-growing hardwoods  

SciTech Connect

A biotechnology research program was initiated to develop new clones of fast-growing Populus clones resistant to the herbicide glyphosate and resistant to the leaf-spot and canker disease caused by the fungus Septoria musiva. Glyphosate-resistant callus was selected from stem segments cultured in vitro on media supplemented with the herbicide. Plants were regenerated from the glyphosate-resistant callus tissue. A portion of plants reverted to a glyphosate susceptible phenotype during organogenesis. A biologically active filtrate was prepared from S. musiva and influenced fresh weight of Populus callus tissue. Disease-resistant plants were produced through somaclonal variation when shoots developed on stem internodes cultured in vitro. Plantlets were screened for disease symptoms after spraying with a suspension of fungal spores. A frequency of 0.83 percent variant production was observed. Genetically engineered plants were produced after treatment of plant tissue with Agrobacterium tumefasciens strains carrying plasmid genes for antibiotic resistance. Transformers were selected on media enriched with the antibiotic, kanamycin. Presence of foreign DNA was confirmed by Southern blot analysis. Protoplasts of popular were produced but did not regenerate into plant organs. 145 refs., 12 figs., 36 tabs.

Growing Crystaline Sapphire Fibers By Laser Heated Pedestal Techiques  

DOE Patents (OSTI)

An improved system and process for growing crystal fibers comprising a means for creating a laser beam having a substantially constant intensity profile through its cross sectional area, means for directing the laser beam at a portion of solid feed material located within a fiber growth chamber to form molten feed material, means to support a seed fiber above the molten feed material, means to translate the seed fiber towards and away from the molten feed material so that the seed fiber can make contact with the molten feed material, fuse to the molten feed material and then be withdrawn away from the molten feed material whereby the molten feed material is drawn off in the form of a crystal fiber. The means for creating a laser beam having a substantially constant intensity profile through its cross sectional area includes transforming a previously generated laser beam having a conventional gaussian intensity profile through its cross sectional area into a laser beam having a substantially constant intensity profile through its cross sectional area by passing the previously generated laser beam through a graded reflectivity mirror. The means for directing the laser beam at a portion of solid feed material is configured to direct the laser beam at a target zone which contains the molten feed material and a portion of crystal fiber drawn off the molten feed material by the seed fiber. The means to support the seed fiber above the molten feed material is positioned at a predetermined height above the molten feed material. This predetermined height provides the seed fiber with sufficient length and sufficient resiliency so that surface tension in the molten feed material can move the seed fiber to the center of the molten feed material irrespective of where the seed fiber makes contact with the molten feed material. The internal atmosphere of the fiber growth chamber is composed substantially of Helium gas.

How to Grow Superconducting Crystals How to Grow Superconducting Crystals Photo of the Week: How to Grow Superconducting Crystals September 13, 2013 - 11:29am Addthis Many of the materials that scientists work with at Brookhaven National Laboratory are too small and too precise for traditional tools. In cases like these, the labs grow materials instead of building them. Brookhaven physicist Genda Gu pioneered techniques that grow some of the largest single-crystal high-temperature superconductors in the world. The glowing chamber in this photo grows superconducting crystals. To do so, the furnace focuses infrared light onto a rod, melting it around 4,000 degrees Fahrenheit. Under just the right conditions, the liquefied material recrystallizes as a single uniform structure, which is highly sensitive and takes about one month to form. | Photo courtesy of Brookhaven National Laboratory.

Large-scale perturbations due to a small-scale instability in a finite-conductivity plasma  

SciTech Connect

By considering kink modes in a plasma cylinder in a strong axial magnetic field as an example, it is demonstrated that, because of the finite plasma conductivity (the finite longitudinal plasma permittivity {epsilon}{sub parallel}), large-scale perturbations can grow with time due to a small-scale instability that develops near a certain magnetic surface.

Is Hubble's Expansion due to Dark Energy  

E-Print Network (OSTI)

{\\it The universe is expanding} is known (through Galaxy observations) since 1929 through Hubble's discovery ($V = H D$). Recently in 1999, it is found (through Supernovae observations) that the universe is not simply expanding but is accelerating too. We, however, hardly know only $4\\%$ of the universe. The Wilkinson Microwave Anisotropy Probe (WMAP) satellite observational data suggest $73\\%$ content of the universe in the form of dark-energy, $23\\%$ in the form of non-baryonic dark-matter and the rest $4\\%$ in the form of the usual baryonic matter. The acceleration of the universe is ascribed to this dark-energy with bizarre properties (repulsive-gravity). The question is that whether Hubble's expansion is just due to the shock of big-bang & inflation or it is due to the repulsive-gravity of dark-energy? Now, it is believed to be due to dark-energy, say, by re-introducing the once-discarded cosmological-constant $\\Lambda$. In the present paper, it is shown that `the formula for acceleration due to dark-energy' is (almost) exactly of same-form as `the acceleration formula from the Hubble's law'. Hence, it is concluded that: yes, `indeed it is the dark-energy responsible for the Hubble's expansion too, in-addition to the current on-going acceleration of the universe'.

Extreme events due to localisation of energy  

E-Print Network (OSTI)

We study a one-dimensional chain of harmonically coupled units in an asymmetric anharmonic soft potential. Due to nonlinear localisation of energy, this system exhibits extreme events in the sense that individual elements of the chain show very large excitations. A detailed statistical analysis of extremes in this system reveals some unexpected properties, e.g., a pronounced pattern in the inter event interval statistics. We relate these statistical properties to underlying system dynamics, and notice that often when extreme events occur the system dynamics adopts (at least locally) an oscillatory behaviour, resulting in, for example, a quick succession of such events. The model therefore might serve as a paradigmatic model for the study of the interplay of nonlinearity, energy transport, and extreme events.

Sound Speed Perturbations Due to Internal Tides  

Science Journals Connector (OSTI)

Internal tides are perhaps the most prevalent and largest amplitude internal gravity waves in the ocean. They are commonly generated by the scattering of surfacetidal energy into internal modes when the surfacetides propagate on to continental shelves. A portion of the internal tidal energy propagates into the deep ocean. One of the effects of internal tides on underwater acoustic propagation is to perturb the temperature and salinity versus depth profiles and thus the sound speed versus depth profile. Starting with temperature and salinity versus depth profiles from near Eleuthera Island the internal tide eigenfunctions as well as the sound speed profile have been computed for a water depth of 4500 m. Assuming a value for the vertical displacement amplitude of a first vertical mode internal tide the perturbed temperature and salinity profiles have been computed. From these perturbed profiles the consequent perturbed sound speed profiles have been computed for cases of maximum up and down internal tide displacement. The first mode internal tide has no vertical displacement at the sea surface and bottom and a maximum near the base of the main thermocline (depth of about 1200 m). Since the SOFAR axis is also near the base of the main thermocline and since the pressureeffects on sound speed are predominant below the SOFAR axis the sound speed perturbation due to the first mode internal tide is greatest at a depth (about 550 m) above the SOFAR axis. An internal tide with a maximum vertical displacement of 10 m produces a maximum sound speed perturbation of 0.7 m/sec.

Infrared Lorentz Violation and Slowly Instantaneous Electricity  

Science Journals Connector (OSTI)

We study a modification of electromagnetism which violates Lorentz invariance at large distances. In this theory, electromagnetic waves are massive, but the static force between charged particles is Coulomb, not Yukawa. At very short distances the theory looks just like QED. But for distances larger than 1/m the massive dispersion relation of the waves can be appreciated, and the Coulomb force can be used to communicate faster than the speed of light. In fact, electrical signals are transmitted instantly, but take a time ?1/m to build up to full strength. After that, undamped oscillations of the electric field are set in and continue until they are dispersed by the arrival of the Lorentz-obeying part of the transmission. Experimental constraints imply that the Compton wavelength of the photon may be as small as 6000km. This bound is weaker than for a Lorentz-invariant mass, essentially because the Coulomb constraint is removed.

Environmental and societal consequences of a possible CO/sub 2/-induced climate change. Volume II, Part 8. Impacts of rising atmospheric carbon dioxide levels on agricultural growing seasons and crop water use efficiencies  

SciTech Connect

The researchable areas addressed relate to the possible impacts of climate change on agricultural growing seasons and crop adaptation responses on a global basis. The research activities proposed are divided into the following two main areas of investigation: anticipated climate change impacts on the physical environmental characteristics of the agricultural growing seasons and, the most probable food crop responses to the possible changes in atmospheric CO/sub 2/ levels in plant environments. The main physical environmental impacts considered are the changes in temperature, or more directly, thermal energy levels and the growing season evapotranspiration-precipitation balances. The resulting food crop, commercial forest and rangeland species response impacts addressed relate to potential geographical shifts in agricultural growing seasons as determined by the length in days of the frost free period, thermal energy changes and water balance changes. In addition, the interaction of possible changes in plant water use efficiencies during the growing season in relationship to changing atmospheric CO/sub 2/ concentrations, is also considered under the scenario of global warming due to increases in atmospheric CO/sub 2/ concentration. These proposed research investigations are followed by adaptive response evaluations.

World oil demands shift toward faster growing and less price-responsive products and regions  

Science Journals Connector (OSTI)

Using data for 19712008, we estimate the effects of changes in price and income on world oil demand, disaggregated by product transport oil, fuel oil (residual and heating oil), and other oil for six groups of countries. Most of the demand reductions since 197374 were due to fuel-switching away from fuel oil, especially in the OECD; in addition, the collapse of the Former Soviet Union (FSU) reduced their oil consumption substantially. Demand for transport and other oil was much less price-responsive, and has grown almost as rapidly as income, especially outside the OECD and FSU. World oil demand has shifted toward products and regions that are faster growing and less price-responsive. In contrast to projections to 2030 of declining per-capita demand for the world as a whole by the U.S. Department of Energy (DOE), International Energy Agency (IEA) and OPEC we project modest growth. Our projections for total world demand in 2030 are at least 20% higher than projections by those three institutions, using similar assumptions about income growth and oil prices, because we project rest-of-world growth that is consistent with historical patterns, in contrast to the dramatic slowdowns which they project.

In the second phase, refinement of the tumour contour is achieved by using the region growing method. The results are good and visually validated by radiologists.

Response to Comments on "A Bacterium That Can Grow Using Arsenic Instead of Phosphorus"  

SciTech Connect

Concerns have been raised about our recent study describing a bacterium that can grow using arsenic (As) instead of phosphorus (P). Our data suggested that As could act as a substitute for P in major biomolecules in this organism. Although the issues raised are of investigative interest, we contend that they do not invalidate our conclusions. We argue that while no single line of evidence we presented was sufficient to support our interpretation of the data, taken as an entire dataset we find no plausible alternative to our conclusions. Here we reply to the critiques and provide additional arguments supporting the assessment of the data we reported.

Growing Dynamical Facilitation on Approaching the Random Pinning Colloidal Glass Transition  

E-Print Network (OSTI)

Despite decades of research, it remains to be established whether the transformation of a liquid into a glass is fundamentally thermodynamic or dynamic in origin. While observations of growing length scales are consistent with thermodynamic perspectives like the Random First-Order Transition theory (RFOT), the purely dynamic approach of the Dynamical Facilitation (DF) theory lacks experimental validation. Further, for glass transitions induced by randomly freezing a subset of particles in the liquid phase, simulations support the predictions of RFOT, whereas the DF theory remains unexplored. Here, using video microscopy and holographic optical tweezers, we show that dynamical facilitation in a colloidal glass-forming liquid unambiguously grows with density as well as the fraction of pinned particles. In addition, we show that heterogeneous dynamics in the form of string-like cooperative motion, which is believed to be consistent with RFOT, emerges naturally within the framework of facilitation. Most importantly, our findings demonstrate that a purely dynamic origin of the glass transition cannot be ruled out.

On atomic structure of Ge huts growing on the Ge/Si(001) wetting layer  

SciTech Connect

Structural models of growing Ge hut clusterspyramids and wedgesare proposed on the basis of data of recent STM investigations of nucleation and growth of Ge huts on the Si(001) surface in the process of molecular beam epitaxy. It is shown that extension of a hut base along <110> directions goes non-uniformly during the cluster growth regardless of its shape. Growing pyramids, starting from the second monolayer, pass through cyclic formation of slightly asymmetrical and symmetrical clusters, with symmetrical ones appearing after addition of every fourth monolayer. We suppose that pyramids of symmetrical configurations composed by 2, 6, 10, etc., monolayers over the wetting layer are more stable than asymmetrical ones. This might explain less stability of pyramids in comparison with wedges in dense arrays forming at low temperatures of Ge deposition. Possible nucleation processes of pyramids and wedges on wetting layer patches from identical embryos composed by 8 dimers through formation of 1 monolayer high 16-dimer nuclei different only in their symmetry is discussed. Schematics of these processes are presented. It is concluded from precise STM measurements that top layers of wetting layer patches are relaxed when huts nucleate on them.

Minimizing the total cost of hen allocation to poultry farms using hybrid Growing Neural Gas approach  

Science Journals Connector (OSTI)

Abstract In this paper a decision support system to solve the problem of hen allocation to hen houses with the aim of minimizing the total cost is described. The total cost consists of farm utilization cost, hen transportation cost, and loss from mixing hens at different ages in the same hen houses. Clustering of hen houses using the traditional Growing Neural Gas (GNG) was first determined to allocate hens to the hen houses effectively. However, the traditional GNG often solves the clustering problem by considering distance only. Therefore the hybrid Growing Neural Gas (hGNG) considering both the distance from the centroids of the clusters to the hen houses and the weights of hen house sizes was proposed to solve the problem. In the second phase, allocating and determining routes to allocate hens to the hen houses using the nearest neighbor approach were carried out in order to minimize the total distance. The performance of the algorithm was measured using the relative improvement (RI), which compares the total costs of the hGNG and GNG algorithms and the current practice. The results obtained from this study show that the hGNG algorithm provides better total cost values than the firms current practice from 7.92% to 20.83%, and from 5.90% to 17.91% better than the traditional GNG algorithm. The results also demonstrate that the proposed method is useful not only for reducing the total cost, but also for efficient management of a poultry production system. Furthermore, the method used in this research should prove beneficial to other similar agro-food sectors in Thailand and around the world.

Mn, Fe, Zn and As speciation in a fast-growing ferromanganese marine nodule  

SciTech Connect

The speciation of Mn, Fe, As and Zn in a fast-growing (0.02mm/yr), shallow-marine ferromanganese nodule has been examined by micro X-ray fluorescence, micro X-ray diffraction, and micro X-ray absorption spectroscopy. This nodule exhibits alternating Fe-rich and Mn-rich layers reflecting redox variations in water chemistry. Fe occurs as two-line ferrihydrite. The As is strictly associated with Fe and is mostly pentavalent, with an environment similar to that of As sorbed on or coprecipitated with synthetic ferrihydrite. The Mn is in the form of turbostratic birnessite with {approx} 10 percent trivalent manganese in the layers and probably {approx} 8 percent corner-sharing metal octahedra in the interlayers. The Zn is enriched on the rim of the nodule, associated with Mn. The Zn is completely (>90 percent) tetrahedrally coordinated and sorbed in the interlayers of birnessite on vacant layer Mn sites. The Zn and Mn species are similar to ones found in soils, suggesting common structural principles, despite the differing formation conditions in these systems.

Comparative study of microstructural characteristics of electrospark and Nd:YAG laser epitaxially growing coatings  

Science Journals Connector (OSTI)

As low-heat input welding processes, electrospark deposition and pulsed Nd:YAG laser cladding can be commonly used to prepare epitaxially growing coatings. However, these two processes have quite different characteristics in the energy input, the amount of materials involved, and the temperature gradient, and hence might result in dissimilar microstructural characteristics. In this paper, a comparative study has been made between microstructural characteristics in epitaxial growth coatings prepared by electrospark deposition and pulsed Nd:YAG laser cladding. Some interesting results have been achieved. Firstly, epitaxial growth coatings can be commonly achieved by these two techniques. Secondly, microstructural morphologies of these two epitaxial growth coatings are obviously different, cellular columnar structure prevails in the electrospark coating while columnar dendritic structure occupies most of the laser coating thickness, more importantly, electrospark coating remains fully columnar in the whole layer whereas laser coating tends to change from columnar to equiaxed at the top of the layer. Thirdly, electrospark coating possesses finer and more homogeneous microstructure than laser coating.

Sound radiation due to rapid deformation of an impacted plate  

Science Journals Connector (OSTI)

Sound radiation due to forced deformation of an impacted plate was investigated. An initial sound pressure pulse due to rapid local deformation of a plate was generated before the radiation from natural modes of the plate occurred. On the axis of impact near the plate a distinct pressure pulse is observed to reproduce the velocity waveform of the plate at the opposite side of the impact point. Data from experiments involving impact of spheres on plates differing in size and material properties are presented to show the plate behavior and the radiated soundpressure. Theoretical results were obtained from an analytical model in which impulsive acceleration of a plate with Gaussian spatial distribution is convoluted with the acceleration?time history of the actual impact. Theoretical results for the on?axis pressure are compared with the experimental results.

The electrical resistance due to nonmagnetic impurities in ferromagnetic metals  

Science Journals Connector (OSTI)

We discuss the electrical resistance due to nonmagnetic impurities in ferromagnetic metals. The impurity resistance depends on the magnetization of the host metal since (1) the densities of states of spin electrons at the Fermi surface change with the magnetization of a metal and (2) the screened impurity potential is different for the spin electrons and depends on the magnetization of the metal. The effect of the spin dependent screening on the electrical resistance in ferromagnetic metals was not fully considered previously. We choose a single band model for the metallic electrons and obtain an expression for the resistance which includes both of the above mechanisms (1) and (2) simultaneously and self?consistently. We calculate the changes in resistivity due to nonmagnetic impurities in a ferromagnetic metal as a function of magnetization.

Heat transfer deterioration in tubes caused by bulk flow acceleration due to thermal and frictional influences  

SciTech Connect

Severe deterioration of forced convection heat transfer can be encountered with compressible fluids flowing through strongly heated tubes of relatively small bore as the flow accelerates and turbulence is reduced because of the fluid density falling (as the temperature rises and the pressure falls due to thermal and frictional influence). The model presented here throws new light on how the dependence of density on both temperature and pressure can affect turbulence and heat transfer and it explains why the empirical equations currently available for calculating effectiveness of forced convection heat transfer under conditions of strong non-uniformity of fluid properties sometimes fail to reproduce observed behaviour. It provides a criterion for establishing the conditions under which such deterioration of heat transfer might be encountered and enables heat transfer coefficients to be determined when such deterioration occurs. The analysis presented here is for a gaseous fluid at normal pressure subjected strong non-uniformity of fluid properties by the application of large temperature differences. Thus the model leads to equations which describe deterioration of heat transfer in terms of familiar parameters such as Mach number, Reynolds number and Prandtl number. It is applicable to thermal power plant systems such as rocket engines, gas turbines and high temperature gas-cooled nuclear reactors. However, the ideas involved apply equally well to fluids at supercritical pressure. Impairment of heat transfer under such conditions has become a matter of growing interest with the active consideration now being given to advanced water-cooled nuclear reactors designed to operate at pressures above the critical value.

Identification of Argentinian saline drylands suitable for growing Salicornia bigelovii for bioenergy  

Science Journals Connector (OSTI)

Abstract Salicornia bigelovii is an oilseed halophyte species that can be grown using saltwater in saline and coastal areas where conventional crops cannot be grown. Due to its high oil content, comparable with commercial crops, is a promising feedstock for biodiesel production. To determine the agroclimatic zoning of S. bigelovii in Argentina, thermal and rainfall indexes from its center of origin were taken into account and plotted for the period 19812010. The overlapping of the temperature and rainfall maps defined the agroclimatic zoning which determined optimal, very suitable, suitable, marginal and non-suitable areas for cultivation of S. bigelovii in Argentina. Subsequently, the Dryland Salinity classification of FAO was used to identify putative sites of implantation of S. bigelovii in moderately and strongly saline phases where soil electrical conductivity ranges from 12.4 to 22.1mmhos/cm. Finally, the overlapping of both the agroclimatic suitability and Dryland Salinity maps afforded the agro-ecological suitability map, which showed the same five fitness classes defined in the agroclimatic zoning.

Using RPS Policies to Grow the Solar Market in the United States  

SciTech Connect

The market for photovoltaics in the United States remains small relative to the nation's solar resource potential. Nonetheless, annual grid-connected PV installations have grown from just 4 MW in 2000 to over 100 MW in 2006, fast enough to the catch the attention of the global solar industry. The state of California deserves much of the credit for this growth. The State's historical rebate programs resulted in roughly 75% of the nation's grid-connected PV additions from 2000 through 2006 being located in California, and the $3 billion California Solar Initiative will ensure that the State remains a mainstay of the US solar industry for years to come. But California is not the only market for solar in the US; other states have recently developed policies that may rival those of the western state in terms of future growth potential. In particular, 25 states, as well as Washington, D.C., have established renewables portfolio standards (RPS), sometimes called quota systems in Europe, requiring electricity suppliers in those states to source a minimum portion of their need from renewable electricity. (Because a national RPS is not yet in place, my focus here is on state policies). Under many of these state policies, solar is not expected to fare particularly well: PV installations simply cannot compete on cost or scale with large wind plants in the US, at least not yet. In response, an expanding list of states have established solar or distributed generation (DG) set-asides within their RPS policies, effectively requiring that some fraction of RPS-driven supply derive from solar energy. The popularity of set-asides for solar and/or DG has increased dramatically in recent years. Already, 11 states and D.C. have developed such RPS set-asides. These include states with outstanding solar resources, such as Nevada, Arizona, Colorado, and New Mexico, as well as areas where the solar resource is less robust, including North Carolina, Maryland, Pennsylvania, New Jersey, New York, New Hampshire, Delaware, and DC. Among those states with set-asides, two are restricted to PV applications, nine also allow solar-thermal electric to qualify, three allow solar heating and/or cooling to qualify, and three have broader renewable DG set-asides. The policies also differ in their targets and timeframes, whether projects must be located in-state, the application of cost caps, and the degree of oversight on how suppliers contract with solar projects. Only three of these states have more than two years of experience with solar or DG set-asides so far: Arizona, Nevada, and New Jersey. And yet, despite the embryonic stage of these policies, they have already begun to have a significant impact on the grid-connected PV market. From 2000-2006, 16% (or 48 MW) of grid-connected PV installations in the US occurred in states with such set-asides, a percentage that increases to 67% if one only considers PV additions outside of California. The importance of these programs is growing and will continue to expand. In fact, if one assumes (admittedly somewhat optimistically) that these policies will be fully achieved, then existing state solar or DG set-asides could result in 400 MW of solar capacity by 2010, 2,000 MW by 2015, and 6,500 MW by 2025. This equates to annual additions of roughly 100 MW through 2010, increasing to over 500 MW per year by 2015 and 700 MW per year by 2020. PV is not assured of all of this capacity, and will receive strong competition from solar-thermal electric facilities in the desert southwest. Nonetheless, set-asides in those states outside of the southwest will favor PV, and even some of the southwestern states have designed their RPS programs to ensure that PV fares well, relative to other forms of solar energy. Since 2000, Arizona and, more recently, New Jersey have represented the largest solar set-aside-driven PV markets. Even more-recent additions are coming from Colorado, Nevada, New York, and Pennsylvania. In the long-term, the largest markets for solar electricity are predicted to include New Jersey, Maryland, Arizona, and P

Charge Transport Anisotropy Due to Grain Boundaries in Directionally  

NLE Websites -- All DOE Office Websites (Extended Search)

Charge Transport Anisotropy Due to Grain Charge Transport Anisotropy Due to Grain Boundaries in Directionally Crystallized Thin Films of Regio-Regular Poly(3-hexylthiophene) Semicrystalline polymers, such as polythiophenes, hold much promise as active layers in printable electronic devices such as photovoltaic cells, sensors, and thin film transistors. As organic semiconductors approach commercialization, there is a need to better understand the relationship between charge transport and microstructure, in particular, to identify the inherent bottlenecks to charge transport. In semicrystalline and polycrystalline materials, charge transport is most likely dominated by grain-boundary effects, although the exact mechanism is not well understood. Unfortunately, grain boundaries in semicrystalline thin films are difficult to characterize: the grains are too small to allow for measurements across individual grain boundaries (as is often done for polycrystalline films of small molecules) and bulk measurements are complicated by the unknown orientation of polymer chains within the grain. To better understand the effect of chain orientation on grain boundaries, we use anisotropic thin films of poly(3-hexylthiophene) (P3HT) - one of the most well-studied polymeric semiconductors, as a tool to study charge transport.

Coalbed methane: A partial solution to Indonesia`s growing energy problems  

SciTech Connect

Indonesia contains the largest resources of coal in Southeast Asia. Indonesian scientists estimate that the in-place coalbed methane resource in 16 onshore basins is about 213 Tcf ({approximately}6 Tcm). This volume is approximately double Indonesia`s current reserves of natural gas. Indonesia is a rapidly industrializing nation of 186 million people, of which 111 million live in Java and 38 million in Sumatra. As industrialization progresses from the present low level, the growth in energy demand will be very rapid. Indonesia`s domestic gas demand is expected to increase form 1.6 Bcf/d (0.05 Bcm/d) in 1991 to 5.7 Bcf/d (0.2 Bcm/d) in 2021. Because the major gas resources of East Kalimantan, North Sumatra, and Natuna are so remote from the main consuming area in northwest Java and are dedicated for export by virtue of the national energy policy, the need is becoming urgent to develop new resources of natural gas, including coalbed methane, for the domestic market. Due to the high geothermal gradient, the coal deposits in the back-arc basins of Sumatra and Java are expected to be of higher than normal rank at depths favorable for coalbed methane production. The oil- and gas-productive Jatibarang sub-basin in northwest Java, with estimated in-place resources of coalbed methane in excess of 20 Tcf (0.6 Tcm), is considered to be the most prospective area in Indonesia for the near-term development of coalbed methane. This area includes Jakarta and vicinity, the most populous and most heavily industrialized part of Indonesia.

Moisture Risk in Unvented Attics Due to Air Leakage Paths  

SciTech Connect

IBACOS completed an initial analysis of moisture damage potential in an unvented attic insulated with closed-cell spray polyurethane foam. To complete this analysis, the research team collected field data, used computational fluid dynamics to quantify the airflow rates through individual airflow (crack) paths, simulated hourly flow rates through the leakage paths with CONTAM software, correlated the CONTAM flow rates with indoor humidity ratios from Building Energy Optimization software, and used Warme und Feuchte instationar Pro two-dimensional modeling to determine the moisture content of the building materials surrounding the cracks. Given the number of simplifying assumptions and numerical models associated with this analysis, the results indicate that localized damage due to high moisture content of the roof sheathing is possible under very low airflow rates. Reducing the number of assumptions and approximations through field studies and laboratory experiments would be valuable to understand the real-world moisture damage potential in unvented attics.

REDUCTION OF DRIFT EFFECTS DUE TO SOLAR WIND TURBULENCE  

SciTech Connect

Gradient and curvature drift play a key role in the modulation of cosmic rays. Reduction in the drift coefficient due to turbulence has been demonstrated unambiguously through direct numerical simulations, but a theory that can explain these results is still lacking. We introduce a parameterized form of the drift coefficient based on direct numerical simulations and show that good agreement with observed proton energy spectra at Earth can be found when it is used in a numerical modulation model. We show that the turbulence ultrascale, for which no observations currently exist, plays an important role in drift reduction. The magnitude at Earth and spatial dependence of this quantity required to fit cosmic-ray observations at Earth are argued to be plausible based on the required properties of the two-dimensional turbulence spectrum at large scales.

Changes in Dimethyl Sulfide Oceanic Distribution due to Climate Change  

SciTech Connect

Dimethyl sulfide (DMS) is one of the major precursors for aerosols and cloud condensation nuclei in the marine boundary layer over much of the remote ocean. Here they report on coupled climate simulations with a state-of-the-art global ocean biogeochemical model for DMS distribution and fluxes using present-day and future atmospheric CO{sub 2} concentrations. They find changes in zonal averaged DMS flux to the atmosphere of over 150% in the Southern Ocean. This is due to concurrent sea ice changes and ocean ecosystem composition shifts caused by changes in temperature, mixing, nutrient, and light regimes. The largest changes occur in a region already sensitive to climate change, so any resultant local CLAW/Gaia feedback of DMS on clouds, and thus radiative forcing, will be particularly important. A comparison of these results to prior studies shows that increasing model complexity is associted with reduced DMS emissions at the equator and increased emissions at high latitudes.

Optical analog of Rabi oscillation suppression due to atomic motion  

E-Print Network (OSTI)

The Rabi oscillations of a two-level atom illuminated by a laser on resonance with the atomic transition may be suppressed by the atomic motion through averaging or filtering mechanisms. The optical analogs of these velocity effects are described. The two atomic levels correspond in the optical analogy to orthogonal polarizations of light and the Rabi oscillations to polarization oscillations in a medium which is optically active, naturally or due to a magnetic field. In the later case, the two orthogonal polarizations could be selected by choosing the orientation of the magnetic field, and one of them be filtered out. It is argued that the time-dependent optical polarization oscillations or their suppression are observable with current technology.

Abstract Thirty samples of wheat milling by-products (wheat bran, wheat middlings, wheat shorts, wheat red dog, wheat feed flour), collected from 11 flour mills, were fed to growing pigs to determine their digestible energy (DE) and metabolizable energy (ME) content and to establish equations for predicting their DE and ME content based on chemical analysis. The basal diet was based on corn and soybean meal while the other 30 experimental diets contained 290.4g/kg wheat milling by-products added at the expense of corn and soybean meal. The 31 diets were fed to 96 growing pigs (BW=61.93.2kg) according to a completely randomized design during two successive periods. During each period, the 30 experimental diets were fed to three pigs and the basal diet was fed to six pigs, resulting in 6 replications per experimental diet and 12 replications for the basal diet over the two periods. The chemical composition of the 30 samples was variable, and starch and fiber content had a strong negative correlation (r=?0.96 to ?0.99 for CF and ADF, respectively). The DE content of wheat feed flour, wheat red dog, wheat shorts, wheat middlings and wheat bran averaged 17.4, 16.9, 15.2, 12.5 and 12.0MJ/kg DM, respectively. From the stepwise regression analysis, a series of DE and ME prediction equations were generated. The best fit equations for wheat milling by-products were: DE (MJ/kg DM)=19.2?(0.016aNDF) with R2=0.94, RSD=0.58 and Pcontent varied substantially and various correlated single predictors (aNDF, ash, CF, starch, etc.) can be used to accurately predict the DE and ME content when fed to growing pigs.

Assessment of annoyance due to wind turbine noise  

Science Journals Connector (OSTI)

The overall aim of this study was to evaluate the perception and annoyance of noise from wind turbines in populated areas of Poland. The study group comprised 156 subjects. All subjects were interviewed using a questionnaire developed to enable evaluation of their living conditions including prevalence of annoyance due to noise from wind turbines and the self-assessment of physical health and wellbeing. In addition current mental health status of respondents was assessed using Goldberg General Health Questionnaire GHQ-12. For areas where respondents lived A-weighted sound pressure levels (SPLs) were calculated as the sum of the contributions from the wind power plants in the specific area. It has been shown that the wind turbine noise at the calculated A-weighted SPL of 30?48 dB was perceived as annoying outdoors by about one third of respondents while indoors by one fifth of them. The proportions of the respondents annoyed by the wind turbine noise increased with increasing A-weighted sound pressure level. Subjects' attitude to wind turbines in general and sensitivity to landscape littering was found to have significant impact on the perceived annoyance. Further studies are needed including a larger number of respondents before firm conclusions can be drawn.

Simulating environmental changes due to marine hydrokinetic energy installations.  

SciTech Connect

Marine hydrokinetic (MHK) projects will extract energy from ocean currents and tides, thereby altering water velocities and currents in the site's waterway. These hydrodynamics changes can potentially affect the ecosystem, both near the MHK installation and in surrounding (i.e., far field) regions. In both marine and freshwater environments, devices will remove energy (momentum) from the system, potentially altering water quality and sediment dynamics. In estuaries, tidal ranges and residence times could change (either increasing or decreasing depending on system flow properties and where the effects are being measured). Effects will be proportional to the number and size of structures installed, with large MHK projects having the greatest potential effects and requiring the most in-depth analyses. This work implements modification to an existing flow, sediment dynamics, and water-quality code (SNL-EFDC) to qualify, quantify, and visualize the influence of MHK-device momentum/energy extraction at a representative site. New algorithms simulate changes to system fluid dynamics due to removal of momentum and reflect commensurate changes in turbulent kinetic energy and its dissipation rate. A generic model is developed to demonstrate corresponding changes to erosion, sediment dynamics, and water quality. Also, bed-slope effects on sediment erosion and bedload velocity are incorporated to better understand scour potential.

New frontiers in oilseed biotechnology: meeting the growing global demand for vegetable oils for food, feed, biofuel, and industrial uses.  

SciTech Connect

Vegetable oils have historically been a valued commodity for food use and to a lesser extent for non-edible applications such as detergents and lubricants. The increasing reliance on biodiesel as a transportation fuel has contributed to rising demand and higher prices for vegetable oils. Biotechnology offers a number of solutions to meet the growing need for affordable vegetable oils and vegetable oils with improved fatty acid compositions for food and industrial uses. New insights into oilseed metabolism and its transcriptional control are enabling biotechnological enhancement of oil content and quality. Alternative crop platforms and emerging technologies for metabolic engineering also hold promise for meeting global demand for vegetable oils and for enhancing nutritional, industrial, and biofuel properties of vegetable oils. Here, we highlight recent advances in our understanding of oilseed metabolism and in the development of new oilseed platforms and metabolic engineering technologies.

An Approach for Assessing the Signature Quality of Various Chemical Assays when Predicting the Culture Media Used to Grow Microorganisms  

SciTech Connect

We demonstrate an approach for assessing the quality of a signature system designed to predict the culture medium used to grow a microorganism. The system was comprised of four chemical assays designed to identify various ingredients that could be used to produce the culture medium. The analytical measurements resulting from any combination of these four assays can be used in a Bayesian network to predict the probabilities that the microorganism was grown using one of eleven culture media. We evaluated combinations of the signature system by removing one or more of the assays from the Bayes network. We measured and compared the quality of the various Bayes nets in terms of fidelity, cost, risk, and utility, a method we refer to as Signature Quality Metrics

Exploiting the randomness of the measurement basis in quantum cryptography: Secure Quantum Key Growing without Privacy Amplification  

E-Print Network (OSTI)

We suggest that the randomness of the choices of measurement basis by Alice and Bob provides an additional important resource for quantum cryptography. As a specific application, we present a novel protocol for quantum key distribution (QKD) which enhances the BB84 scheme by encrypting the information sent over the classical channel during key sifting. We show that, in the limit of long keys, this process prevents an eavesdropper from reproducing the sifting process carried out by the legitimate users. The inability of the eavesdropper to sift the information gathered by tapping the quantum channel reduces the amount of information that an eavesdropper can gain on the sifted key. We further show that the protocol proposed is self sustaining, and thus allows the growing of a secret key.

Cosmic X-ray Surveys of Distant Active Galaxies: The Demographics, Physics, and Ecology of Growing Supermassive Black Holes  

E-Print Network (OSTI)

We review results from cosmic X-ray surveys of active galactic nuclei (AGNs) over the past ~ 15 yr that have dramatically improved our understanding of growing supermassive black holes (SMBHs) in the distant universe. First, we discuss the utility of such surveys for AGN investigations and the capabilities of the missions making these surveys, emphasizing Chandra, XMM-Newton, and NuSTAR. Second, we briefly describe the main cosmic X-ray surveys, the essential roles of complementary multiwavelength data, and how AGNs are selected from these surveys. We then review key results from these surveys on the AGN population and its evolution ("demographics"), the physical processes operating in AGNs ("physics"), and the interactions between AGNs and their environments ("ecology"). We conclude by describing some significant unresolved questions and prospects for advancing the field.

Direct measurements of growing amorphous order and non-monotonic dynamic correlations in a colloidal glass-former  

E-Print Network (OSTI)

While the transformation of flowing liquids into rigid glasses is omnipresent, a complete understanding of vitrification remains elusive. Of the numerous approaches aimed at solving the glass transition problem, the Random First-Order Theory (RFOT) is the most prominent. However, the existence of the underlying thermodynamic phase transition envisioned by RFOT remains debatable, since its key microscopic predictions concerning the growth of amorphous order and the nature of dynamic correlations lack experimental verification. Here, by using holographic optical tweezers, we freeze a wall of particles in an equilibrium configuration of a 2D colloidal glass-forming liquid and provide direct evidence for growing amorphous order in the form of a static point-to-set length. Most remarkably, we uncover the non-monotonic dependence of dynamic correlations on area fraction and show that this non-monotonicity follows directly from the change in morphology of cooperatively rearranging regions, as predicted by RFOT. Our findings suggest that the glass transition has a thermodynamic origin.

The role of mechanical forces in the planar-to-bulk transition in growing Escherichia coli microcolonies  

E-Print Network (OSTI)

Mechanical forces are obviously important in the assembly of three-dimensional multicellular structures, but their detailed role is often unclear. We have used growing microcolonies of the bacterium \\emph{Escherichia coli} to investigate the role of mechanical forces in the transition from two-dimensional growth (on the interface between a hard surface and a soft agarose pad) to three-dimensional growth (invasion of the agarose). We measure the position within the colony where the invasion transition happens, the cell density within the colony, and the colony size at the transition as functions of the concentration of the agarose. We use a phenomenological theory, combined with individual-based computer simulations, to show how mechanical forces acting between the bacterial cells, and between the bacteria and the surrounding matrix, lead to the complex phenomena observed in our experiments - in particular a non-trivial dependence of the colony size at the transition on the agarose concentration. Matching these approaches leads to a prediction for how the friction coefficient between the bacteria and the agarose should vary with agarose concentration. Our experimental conditions mimic numerous clinical and environmental scenarios in which bacteria invade soft matrices, as well as shedding more general light on the transition between two- and three-dimensional growth in multicellular assemblies.

Energy consumption profile of public housing for lower-mid income families in a fast growing city of Argentina  

Science Journals Connector (OSTI)

A large variety of construction patterns can be found in public-housing programs for lower-mid income families in Santa Rosa, a fast growing city located in a temperate area of central Argentina. Very little attention has been paid to the energy assessment of different patterns that are needed to prescribe energy-saving guidelines for improving the energy performance of housing plans. The objective of this work was to describe the energy profile and understand the energy behaviour of public housing programs which differ in their construction patterns. The annual and seasonal energy behaviour of public and non-public residential dwellings was compared in terms of electricity and gas consumption. A similar comparison between remodelled and non-remodelled dwellings was performed within the public-dwellings sample. Results showed that public and non-public dwellings did not differ in terms of electricity consumption, but they differed greatly in terms of gas consumption. Non-public dwellings, which are larger and heterogeneous, demand more gas for heating during the winter. No difference in annual energy consumption was found in the comparison of remodelled and non-remodelled public dwellings. However, they differ in electricity consumption patterns during the critical winter season: the lower winter consumption of remodelled dwellings could be partially explained by a construction change aimed at lowering the expensive consumption of electricity. In spite of the fact that the energy behaviour of public dwellings seems to be seasonal, dependent upon more than design factors alone, a significant energy saving can be obtained by introducing well-known design technologies.

Tune modulation due to synchrotron oscillations and chromaticity, and the dynamic aperture  

SciTech Connect

A tracking study was done of the effects of a tune modulations, due to synchrotron oscillations and the tune dependence on momentum (chromaticity), on the dynamic aperture. The studies were done using several RHIC lattices and tracking runs of about 1 {times} 10{sup 6} turns. The dynamic aperture was found to decrease roughly linearly with the amplitude of the tune modulation. Lower order non-linear resonances, like the 1/3 and 1/4 resonance are not crossed because of the tune modulation. Three different cases were studied, corresponding to RHIC lattices with different {beta}*, and with different synchrotron oscillation amplitudes. In each case, the tune modulation amplitude was varied by changing the chromaticity. In each case, roughly the same result, was found. The result found here for the effect of a tune modulation due to chromaticity may be compared with the result found for the effect of a tune modulation due to a gradient ripple in the quadrupoles. The effect of a tune modulation due to a gradient ripple appears to be about 4 times stronger than the effect of a tune modulation due to chromaticity and synchrotron oscillations.

Collisionless damping of nonlinear dust ion acoustic wave due to dust charge fluctuation  

Science Journals Connector (OSTI)

A dissipation mechanism for the damping of the nonlinear dust ion acoustic wave in a collisionless dusty plasma consisting of nonthermal electrons, ions, and variable charge dust grains has been investigated. It is shown that the collisionless damping due to dust charge fluctuation causes the nonlinear dust ion acoustic wave propagation to be described by the damped Korteweg-de Vries equation. Due to the presence of nonthermal electrons, the dust ion acoustic wave admits both positive and negative potential and it suffers less damping than the dust acoustic wave, which admits only negative potential.

Tune modulation due to synchrotron oscillations and chromaticity, and the dynamic aperture  

SciTech Connect

A tracking study was done of the effects of a tune modulation, due to synchrotron oscillations and the tune dependence on momentum (chromaticity), on the dynamic aperture. The studies were done using several RHIC lattices and tracking runs of about 1 {times} 10{sup 6} turns. The dynamic aperture was found to decrease roughly linearly with the amplitude of the tune modulation and may be represented by A = A{sub o}(l--10 {Delta}{nu}) where A{sub o} is the dynamic aperture for {Delta}{nu} = 0, and {Delta}{nu} is the tune modulation amplitude. In Eq. (1), the range of {Delta}{nu} is such that lower order non-linear resonances, like the 1/3 and 1/4 resonance axe not crossed because of the tune modulation. Three different cases were studied, corresponding to RHIC lattices with different {beta}*, and with different synchrotron oscillation amplitudes. In each case, the tune modulation amplitude was varied by changing the chromaticity. In each case, roughly the same result, Eq. (1), was found. The result found here for the effect of a tune modulation due to chromaticity may be compared with the result found for the effect of a tune modulation due to a gradient ripple in the quadrupoles, which was A = A{sub o}(l--42 {Delta}{nu}). The effect of a {Delta}{nu} due to a gradient ripple appears to be about 4 times stronger than the effect of a {Delta}{nu} due to chromaticity and synchrotron oscillations.

Though growing much more slowly than the economy from 1975 to 1985, energy use for transportation is now growing at nearly the same rate as GDP. This report describes the analysis of trends in energy use and energy intensity in transportation into components due to, (1) growth in transportation activity, (2) changes in energy intensity, and (3) changes in the modal structure of transportation activities.

Energy shifts of Rydberg atoms due to patch fields near metal surfaces

The statistical properties of patch electric fields due to a polycrystalline metal surface are calculated. The fluctuations in the electric field scale like 1/z{sup 2} when z>>w, where z is the distance to the surface and w is the characteristic length scale of the surface patches. For typical thermally evaporated gold surfaces these field fluctuations are comparable to the image field of an elementary charge, and scale in the same way with distance to the surface. Expressions for calculating the statistics of the inhomogeneous broadening of Rydberg-atom energies due to patch electric fields are presented. Spatial variations in the patch fields over the Rydberg orbit are found to be insignificant.

Why do nanotubes grow chiral?  

E-Print Network (OSTI)

Carbon nanotubes (CNT) hold enormous technological promise. It can only be harnessed if one controls in a practical way the CNT chirality, the feature of the tubular carbon topology that governs all the CNT properties---electronic, optical, mechanical. Experiments in catalytic growth over the last decade have repeatedly revealed a puzzling strong preference towards minimally-chiral (near-armchair) CNT, challenging any existing hypotheses and turning chirality control ever more tantalizing yet leaving its understanding elusive. Here we combine the CNT/catalyst interface thermodynamics with the kinetic growth theory to show that the unusual near-armchair peaks emerge from the two antagonistic trends: energetic preference towards achiral CNT/catalyst interfaces vs. faster growth of chiral CNT. This narrow distribution is profoundly related with the peaked behavior of a simple function, x*exp(-x).

Calculation of the reactivity feedback due to core-assembly bowing in LMFBRs  

SciTech Connect

The nonuniformity of the temperature distribution in an LMFBR leads to differential thermal expansion of the walls of an assembly hexcan. These thermal expansion differentials cause the hexcan to distort or bow. Consequentially, the assembly experiences a spatial displacement, which results in a change in reactivity for the core. A computational model to calculate the reactivity feedback due to material displacements induced by assembly bowing effects has been developed.

Deep dielectric charging effects due to high-energy electrons in earth's outer magnetosphere  

Science Journals Connector (OSTI)

Many spacecraft operational problems in the earth's outer magnetosphere appear to be due to intense, transient radiation phenomena. Three types of naturally occuring, and highly variable, hostile particle radiation environments are encountered at, or near, the geostationary orbit: (1) high-energy protons due to solar flares; (2) energetic ions and electrons produced by magnetospheric substorms; and (3) very-high-energy electrons of uncertain origin. In this paper, particular emphasis is given to highly relativistic electrons (310 MeB). Electron fluxes and energy spectra are shown which were measured by two high-energy electron sensory systems at 6.6RE from 1979 through 1984. Large, persistent increases in this population were found to be relatively infrequent and sporadic in 1978-81 around solar maximum. During the approach to solar minimum (1981-present) it is observed that the highly relastivistic electrons occur with occur with a regular 27-day periodicity, and are well associated with the re-established solar wind stream structures. Through a superposed epoch analysis technique we show that an energetic electron enhancement typically rises on 2- to 3-day time scale and decays on 3- to 4-day scale at essentially all energies above ca. 3 MeV. The present analysis suggests that these electrons have a very deletrious influence on spacecraft systems due to deep dielectric charging and low-dose susceptibility effects.

A general model for chemical erosion of carbon materials due to low-energy H + impact  

Science Journals Connector (OSTI)

Modeling the chemical erosion of carbon materials due to low-energy H + impact is of paramount importance for the prediction of the behavior of carbon-based plasma-facing components in nuclear fusion devices. In this paper a simple general model describing both energy and temperature dependence of carbon-based chemical erosion is presented. Enlightened by Hopfs model {Hopf et al. [J. Appl. Phys.94 2373 (Year: 2003)} the chemical erosion is separated into the contributions from three mechanisms: thermal chemical erosion energetic chemical sputtering and ion-enhanced chemical erosion. Using input from the Monte Carlo code TRIDYN this model is able to reproduce experimental data well.

A new method to estimate the uncertainty due to non-linearity is described on the n= 3 scheme basis. The expression of uncertainty is mathematically derived applying the random walk method. The expression is simple and requires only the temperatures of the fixed points and a relative uncertainty value for each flux-doubling derived from the non-linearity measurement. We also present an example of the method, in which the uncertainty of temperature measurement by a radiation thermometer is calculated on the basis of non-linearity measurement.

Nonlinear dissipation of circularly polarized Alfven waves due to the beam-induced obliquely propagating waves  

SciTech Connect

In the present study, the dissipation processes of circularly polarized Alfven waves in solar wind plasmas including beam components are numerically discussed by using a 2-D hybrid simulation code. Numerical results suggest that the parent Alfven waves are rapidly dissipated due to the presence of the beam-induced obliquely propagating waves, such as kinetic Alfven waves. The nonlinear wave-wave coupling is directly evaluated by using the induction equation for the parent wave. It is also observed both in the 1-D and 2-D simulations that the presence of large amplitude Alfven waves strongly suppresses the beam instabilities.

Optical bistability at low light level due to collective atomic recoil  

E-Print Network (OSTI)

We demonstrate optical nonlinearities due to the interaction of weak optical fields with the collective motion of a strongly dispersive ultracold gas. The combination of a recoil-induced resonance (RIR) in the high gain regime and optical waveguiding within the dispersive medium enables us to achieve a collective atomic cooperativity of $275 \\pm 50$ even in the absence of a cavity. As a result, we observe optical bistability at input powers as low as 20 pW. The present scheme allows for dynamic optical control of the dispersive properties of the ultracold gas using very weak pulses of light. The experimental observations are in good agreement with a theoretical model.

Continuum-kinetic-microscopic model of lung clearance due to core-annular fluid entrainment  

SciTech Connect

The human lung is protected against aspirated infectious and toxic agents by a thin liquid layer lining the interior of the airways. This airway surface liquid is a bilayer composed of a viscoelastic mucus layer supported by a fluid film known as the periciliary liquid. The viscoelastic behavior of the mucus layer is principally due to long-chain polymers known as mucins. The airway surface liquid is cleared from the lung by ciliary transport, surface tension gradients, and airflow shear forces. This work presents a multiscale model of the effect of airflow shear forces, as exerted by tidal breathing and cough, upon clearance. The composition of the mucus layer is complex and variable in time. To avoid the restrictions imposed by adopting a viscoelastic flow model of limited validity, a multiscale computational model is introduced in which the continuum-level properties of the airway surface liquid are determined by microscopic simulation of long-chain polymers. A bridge between microscopic and continuum levels is constructed through a kinetic-level probability density function describing polymer chain configurations. The overall multiscale framework is especially suited to biological problems due to the flexibility afforded in specifying microscopic constituents, and examining the effects of various constituents upon overall mucus transport at the continuum scale.

Prediction of underwater noise and far field propagation due to pile driving for offshore wind farms  

Science Journals Connector (OSTI)

Wind energy plays a key role towards a greener and more sustainable energy generation. Due to limited onshore areas and possible negative effects on human living space offshore wind parks become increasingly popular. However during construction by pile driving high levels of underwater sound emission are observed. To avoid negative effects on marine mammals and other sea life different approaches are currently investigated to cut down the sound pressure levels like e.g. bubble curtains or cofferdams. In order to predict the expected underwater noise both with and without sound damping measures numerical simulation models are needed to avoid complex and costly offshore tests. Within this contribution possible modelling strategies for the prediction of underwater noise due to pile driving are discussed. Different approaches are shown for the direct adjacencies of the pile and for the far field sound propagation. The effectivity of potential noise mitigation measures is investigated using a detailed finite element model of the surroundings of the pile. Far field propagation in the kHz range at distances of several kilometres from the pile on the other hand is computed by a model based on wavenumber integration. Finally the model validation with corresponding offshore tests is addressed.

Wind energy potential assessment considering the uncertainties due to limited data  

Science Journals Connector (OSTI)

A new Bayesian approach is proposed to estimate the annual energy production (AEP) of a site where construction of wind turbines is considered. The approach uses long-term wind speeds of a nearby weather station and short-term wind speeds near the target site. Uncertainties exist due to the limited amount of data in the target site, in addition to the inherent uncertainties in the wind speed, the air density, the surface roughness exponent, and the power performance of the turbine. The proposed method systematically addresses these uncertainties and provides the distribution of the AEP. For illustration, we used the wind speed data near Yeosu, Korea, and the power performance curve of a 3MW turbine. For the site and the turbine studied, the range given by the 95% confidence interval corresponded to 8.9% of the mean AEP, and the range given by the 99% confidence interval corresponded to 11.9% of the mean AEP. Benefits of using the Bayesian approach compared to the classical statistical inference was also illustrated with the case study. The proposed approach provides a more conservative estimation considering the uncertainties due to the limited amount of data. Distributions of parameters of the prediction model are also provided, which enables a more detailed analysis of the prediction.

This is a preliminary report on a joint research project by Boston University and the Kuwait Institute for Scientific Research that commenced in April 1992. The project aim is to establish the extent and nature of environmental damage to the desert surface and coastal zone of Kuwait due to the Gulf War and its aftermath. Change detection image enhancement techniques were employed to enhance environmental change by comparison of Landsat Thematic Mapper images obtained before the wars and after the cessation of the oil and well fires. Higher resolution SPOT images were also utilized to evaluate the nature of the environmental damage to specific areas. The most prominent changes were due to: (1) the deposition of oil and course-grained soot on the desert surface as a result of oil rain'' from the plume that emanated from the oil well fires; (2) the formation of hundreds of oil lakes, from oil seepage at the damaged oil well heads; (3) the mobilization of sand and dust and (4) the pollution of segments of the coastal zone by the deposition of oil from several oil spills. Interpretation of satellite image data are checked in the field to confirm the observations, and to assess the nature of the damage. Final results will be utilized in establishing the needs for remedial action to counteract the harmful effects of the various types of damage to the environment of Kuwait.

Enhanced Ge/Si(001) island areal density and self-organization due to P predeposition  

SciTech Connect

The predeposition of P, with coverages {theta}{sub P} ranging from 0 to 1 ML, on Si(001) significantly increases both the areal density and spatial self-organization of Ge islands grown by gas-source molecular beam epitaxy from hydride precursors. The Ge island density {rho}{sub Ge} initially increases with {theta}{sub P}, reaching a maximum of 1.4 x 10{sup 10} cm{sup -2} at {theta}{sub P} = 0.7 ML, a factor of four times higher than on bare Si(001) under the same deposition conditions, before decreasing at higher P coverages. The increase in {rho}{sub Ge}({theta}{sub P}) is due to a corresponding decrease in Ge adatom mean free paths resulting from passivation of surface dangling bonds by adsorbed pentavalent P atoms which, in addition, leads to surface roughening and, therefore, higher Ge coverages at constant Ge{sub 2}H{sub 6} dose. As {theta}{sub P} (and hence, {rho}{sub Ge}) increases, so does the degree of Ge island ordering along <100> directions due to the anisotropic strain field surrounding individual islands. Similar results are obtained for Ge island growth on P-doped Si(001) layers where strong P surface segregation provides partial monolayer coverage prior to Ge deposition.

Assessing the Significance of Above- and Belowground Carbon Allocation of Fast- and Slow-Growing Families of Loblolly Pine - Final Report  

SciTech Connect

During this project we experimentally evaluated the below-ground biomass and carbon allocation and partitioning of four different fast- and slow-growing families of loblolly pine located in Scotland County, NC, in an effort to increase the long-term performance of the crop. The trees were subjected to optimal nutrition and control since planting in 1993. Destructive harvests in 1998 and 2000 were used for whole?plant biomass estimates and to identify possible family differences in carbon acquisition (photosynthesis) and water use efficiency. At regular intervals throughout each year we sampled tissues for carbohydrate analyses to assess differences in whole-tree carbon storage. Mini rhizotron observation tubes were installed to monitor root system production and turnover. Stable isotope analysis was used to examine possible functional differences in water and nutrient acquisition of root systems between the various families. A genetic dissection of root ontogenic and architectural traits, including biomass partitioning, was conducted using molecular markers to better understand the functional implications of these traits on resource acquisition and whole-plant carbon allocation.

Transient Eddy Current Response Due to a Subsurface Crack in a Conductive Plate  

SciTech Connect

Eddy current nondestructive evaluation (NDE) is usually carried out by exciting a time harmonic field using an inductive probe. However, a viable alternative is to use transient eddy current NDE in which a current pulse in a driver coil produces a transient .eld in a conductor that decays at a rate dependent on the conductivity and the permeability of the material and the coil configuration. By using transient eddy current, it is possible to estimate the properties of the conductive medium and to locate and size potential .aws from the measured probe response. The fundamental study described in this dissertation seeks to establish a theoretical understanding of the transient eddy current NDE. Compared with the Fourier transform method, the derived analytical formulations are more convenient when the transient eddy current response within a narrow time range is evaluated. The theoretical analysis provides a valuable tool to study the effect of layer thickness, location of defect, crack opening as well as the optimization of probe design. Analytical expressions have been developed to evaluate the transient response due to eddy currents in a conductive plate based on two asymptotic series. One series converges rapidly for a short time regime and the other for a long time regime and both of them agree with the results calculated by fast Fourier transform over all the times considered. The idea of asymptotic expansion is further applied to determine the induced electromotive force (EMF) in a pick-up coil due to eddy currents in a cylindrical rod. Starting from frequency domain representation, a quasi-static time domain dyadic Green's function for an electric source in a conductive plate has been derived. The resulting expression has three parts; a free space term, multiple image terms and partial reflection terms. The dyadic Green's function serves as the kernel of an electric field integral equation which defines the interaction of an ideal crack with the transient eddy currents in a conductive plate. The crack response is found using the reciprocity theorem. Good agreement is observed between the predictions of the magnetic field due to the crack and experimental measurements.

Observation of Megagauss-Field Topology Changes due to Magnetic Reconnection in Laser-Produced Plasmas  

SciTech Connect

The spatial structure and temporal evolution of megagauss magnetic fields generated by interactions of up to 4 laser beams with matter were studied with an innovative, time-gated proton radiography method that produces images of unprecedented clarity because it uses an isotropic, truly monoenergetic backlighter (14.7-MeV protons from D{sup 3}He nuclear fusion reactions). Quantitative field maps reveal precisely and directly, for the first time, changes in the magnetic topology due to reconnection in a high-energy-density plasma (n{sub e}{approx}10{sup 20}-10{sup 22} cm{sup -3}, T{sub e}{approx}1 keV)

Electron emission due to positronium annihilation in solid Ar, Kr, and Xe  

Science Journals Connector (OSTI)

We present measurements of positron and electron emission by solid rare-gas surfaces implanted with low-energy positrons. The electron yield exhibits a 0.5-eV-wide peak at a positron energy just above the threshold for positronium (Ps) formation, but below the electron-holepair threshold. A similar peak in the fraction of the incident positrons annihilating in the sample leads us to conclude that (1) slow Ps has an anomalously short diffusion length possibly due to self-trapping, and (2) energetic electrons are liberated from Ps atoms following annihilation of the positrons with valence electrons. The energy spectrum of the emitted electrons should contain information about the internal Ps wave function in the solids.

Failure of man-made cavities in salt and surface subsidence due to sulfur mining  

SciTech Connect

An engineering data base relevant to subsidence due to sulfur mining and to structural failure of cavities in salt is established, evaluated and documented. Nineteen failure events are discussed. Based on these documented failure events, capabilities of and inputs to a mathematical model of cavity failure are determined. Two failure events are adequately documented for use in model verification studies. A conclusion of this study that is pertinent to the Strategic Petroleum Reserve is that cavity failures in dome salt are fairly rare, but that as the number of large cavities (especially those having large roof spans) increases, failures will probably be more common unless stability and failure mechanisms of cavities are better understood.

Transient temperature rise due to ultrasound absorption at a bone/soft-tissue interface  

Science Journals Connector (OSTI)

Thermal effects due to high ultrasound absorption in bone pose an ongoing safety issue. Of considerable concern is the heating of the soft tissue adjacent to the bone surface. Mathematical models can be useful in predicting the transient temperature near the interface during insonation. This paper develops a model that provides the temperature field in terms of simple expressions that convey the functional dependence of the material properties and are easily incorporated into standards and ultrasound machine software yet are able to incorporate the material properties of both bone and soft tissue. The model contains an asymptotic theory based upon a high-attenuation assumption: the distance diffused by heat over the time of interest is large compared to the ultrasound attenuation length. Model predictions of temperature rise and location of maximum temperature were in close agreement with finite-element calculations using parameters appropriate for radiation-force imaging and focused-ultrasound surgery.

Induced Optical Losses in Optoelectronic Devices due to Focused Ion Beam Damages  

E-Print Network (OSTI)

A study of damages caused by gallium focused ion beam (FIB) into III-V compounds is presented. Potential damages caused by local heating, ion implantation, and selective sputtering are presented. Preliminary analysis shows that local heating is negligible. Gallium implantation is shown to occur over areas tens of nanometers thick. Gallium accumulation as well as selective sputtering during III-V compounds milling is expected. Particularly, for GaAs, this effect leads to gallium segregation and formation of metallic clusters. Microdisk resonators were fabricated using FIB milling with different emission currents to analyze these effects on a device. It is shown that for higher emission current, thus higher implantation doses, the cavity quality factor rapidly decreases due to optical scattering losses induced by implanted gallium atoms.

Autonomous Motility of Active Filaments due to Spontaneous Flow-Symmetry Breaking  

E-Print Network (OSTI)

We simulate the nonlocal Stokesian hydrodynamics of an elastic filament which is active due a permanent distribution of stresslets along its contour. A bending instability of an initially straight filament spontaneously breaks flow symmetry and leads to autonomous filament motion which, depending on conformational symmetry, can be translational or rotational. At high ratios of activity to elasticity, the linear instability develops into nonlinear fluctuating states with large amplitude deformations. The dynamics of these states can be qualitatively understood as a superposition of translational and rotational motion associated with filament conformational modes of opposite symmetry. Our results can be tested in molecular-motor filament mixtures, synthetic chains of autocatalytic particles, or other linearly connected systems where chemical energy is converted to mechanical energy in a fluid environment.

Absorption Effects due to Spin in the Worldline Approach to Black Hole Dynamics  

E-Print Network (OSTI)

We generalize the effective point particle approach to black hole dynamics to include spin. In this approach dissipative effects are captured by degrees of freedom localized on the wordline. The absorptive properties of the black hole are determined by correlation functions which can be matched with the graviton absorption cross section in the long wavelength approximation. For rotating black holes, superradiance is responsible for the leading contribution. The effective theory is then used to predict the power loss due to spin in the dynamics of non-relativistic binary systems. An enhancement of three powers of the relative velocity is found with respect to the non-rotating case. Then we generalize the results to other type of constituents in the binary system, such as rotating neutron stars. Finally we compute the power loss absorbed by a test spinning black hole in a given spacetime background.

Effects On Beam Alignment Due To Neutron-Irradiated CCD Images At The National Ignition Facility  

SciTech Connect

The 192 laser beams in the National Ignition Facility (NIF) are automatically aligned to the target-chamber center using images obtained through charged coupled device (CCD) cameras. Several of these cameras are in and around the target chamber during an experiment. Current experiments for the National Ignition Campaign are attempting to achieve nuclear fusion. Neutron yields from these high energy fusion shots expose the alignment cameras to neutron radiation. The present work explores modeling and predicting laser alignment performance degradation due to neutron radiation effects, and demonstrates techniques to mitigate performance degradation. Camera performance models have been created based on the measured camera noise from the cumulative single-shot fluence at the camera location. We have found that the effect of the neutron-generated noise for all shots to date have been well within the alignment tolerance of half a pixel, and image processing techniques can be utilized to reduce the effect even further on the beam alignment.

New perspectives on the damage estimation for buried pipeline systems due to seismic wave propagation  

SciTech Connect

Over the past three decades, seismic fragility fonnulations for buried pipeline systems have been developed following two tendencies: the use of earthquake damage scenarios from several pipeline systems to create general pipeline fragility functions; and, the use of damage scenarios from one pipeline system to create specific-system fragility functions. In this paper, the advantages and disadvantages of both tendencies are analyzed and discussed; in addition, a summary of what can be considered the new challenges for developing better pipeline seismic fragility formulations is discussed. The most important conclusion of this paper states that more efforts are needed to improve the estimation of transient ground strain -the main cause of pipeline damage due to seismic wave propagation; with relevant advances in that research field, new and better fragility formulations could be developed.

Nonequilibrium dynamics of a two-channel Kondo system due to a quantum quench  

Science Journals Connector (OSTI)

Recent experiments by Potok et al. have demonstrated a remarkable tunability between a single-channel Fermi-liquid fixed point and a two-channel non-Fermi-liquid fixed point. Motivated by this we study the nonequilibrium dynamics due to a sudden quench of the parameters of a Hamiltonian from a single-channel to a two-channel anisotropic Kondo system. We find a distinct difference between the long-time behavior of local quantities related to the impurity spin as compared to that of bulk quantities related to the total (conduction electrons plus impurity) spin of the system. In particular, the local impurity spin and the local spin susceptibility are found to equilibrate but in a very slow power-law fashion which is peculiar to the non-Fermi-liquid properties of the Hamiltonian. In contrast, we find a lack of equilibration in the two-particle expectation values related to the total spin of the system.

Shift in the longitudinal sound velocity due to sliding charge-density waves  

Science Journals Connector (OSTI)

The nonlinear conductivity observed for moderate electric fields in NbSe3, TaS3, (TaS4)2I, and K0.3MoO3 below the charge-density-wave-transition is believed to be due to the sliding of the charge-density waves. The sliding motion leads to a Doppler shift of the x-ray diffraction peaks, but this effect has not yet been resolved. We show here that besides the Doppler shift, a sliding incommensurate charge-density wave causes a change in the longitudinal sound velocity of the crystal that is linear in the charge-density-wave velocity. The resulting anisotropic shift is estimated in a mean-field approximation and found to be experimentally observable.

Nonlinear Zeno dynamics due to atomic interactions in Bose-Einstein condensate  

E-Print Network (OSTI)

We show that nonlinear interactions induce both the Zeno and anti-Zeno effects in the generalised Bose-Josephson model (with the on-site interactions and the second-order tunneling) describing Bose-Einstein condensate in double-well trap subject to particle removal from one of the wells. We find that the on-site interactions induce \\textit{only} the Zeno effect, which appears at long evolution times, whereas the second-order tunneling leads to a strong decay of the atomic population at short evolution times, reminiscent of the anti-Zeno effect, and destroys the nonlinear Zeno effect due to the on-site interactions at long times.

Dose calculation errors due to inaccurate representation of heterogeneity correction obtained from computerized tomography  

SciTech Connect

Computerized tomography (CT) is used routinely in evaluating radiation therapy isodose plans. With the introduction of 3D algorithms such as the voxel raytrace, which determines inhomogeneity corrections from actual CT Hounsfield numbers, caution must be used when evaluating isodose calculations. Artifacts from contrast media and dental work, radiopaque markers placed by the treatment planner, and changing bowel and rectal air patterns all have the potential to introduce error into the calculation due to inaccurate assessment of high or low density. Radiopaque makers such as x-spot BB's or solder wire are placed externally on the patient. Barium contrast media introduced at the time of simulation may be necessary to visualize specific anatomical structures on the CT images. While these localization and visualization tools may be necessary, it is important to understand the effects they may introduce in the planning process. Other problems encountered are patient specific and out of the control of the treatment planner. These include high- and low-density streaking caused by dental work, which produce computational errors due to overestimation, and small bowel and rectal air, the patterns of which change on a daily basis and may result in underestimation of structure density. It is important for each treatment planner to have an understanding of how this potentially tainted CT information may be applied in dose calculations and the possible effects they may have. At our institution, the voxel raytrace calculation is automatically forced any time couch angle is introduced. Errors in the calculation from the above mentioned situations may be introduced if a heterogeneity correction is applied. Examples of potential calculation errors and the magnitude of each will be discussed. The methods used to minimize these errors and the possible solutions will also be evaluated.

Estimation of organ and effective dose due to Compton backscatter security scans  

SciTech Connect

Purpose: To estimate organ and effective radiation doses due to backscatter security scanners using Monte Carlo simulations and a voxelized phantom set. Methods: Voxelized phantoms of male and female adults and children were used with the GEANT4 toolkit to simulate a backscatter security scan. The backscatter system was modeled based on specifications available in the literature. The simulations modeled a 50 kVp spectrum with 1.0 mm-aluminum-equivalent filtration and a previously measured exposure of approximately 4.6 {mu}R at 30 cm from the source. Photons and secondary interactions were tracked from the source until they reached zero kinetic energy or exited from the simulation's boundaries. The energy deposited in the phantoms' respective organs was tallied and used to calculate total organ dose and total effective dose for frontal, rear, and full scans with subjects located 30 and 75 cm from the source. Results: For a full screen, all phantoms' total effective doses were below the established 0.25 {mu}Sv standard, with an estimated maximum total effective dose of 0.07 {mu}Sv for full screen of a male child. The estimated maximum organ dose due to a full screen was 1.03 {mu}Gy, deposited in the adipose tissue of the male child phantom when located 30 cm from the source. All organ dose estimates had a coefficient of variation of less than 3% for a frontal scan and less than 11% for a rear scan. Conclusions: Backscatter security scanners deposit dose in organs beyond the skin. The effective dose is below recommended standards set by the Health Physics Society (HPS) and the American National Standards Institute (ANSI) assuming the system provides a maximum exposure of approximately 4.6 {mu}R at 30 cm.

Numerical modelling of salinity variations due to wind and thermohaline forcing in the Persian Gulf  

Science Journals Connector (OSTI)

Salinity is an important component of the marine system. Due to shallow nature of the Persian Gulf, the salinity has been influenced by both wind driven and surface thermohaline fluxes (heat and moisture fluxes). In this study, the seasonal distribution of salinity and its variations due to wind stress and thermohaline forcing are investigated by using a three-dimensional hydrodynamic model, Coupled HydrodynamicalEcological Model for Regional and Shelf Seas (COHERENS). The simulation results show that the salinity in the Persian Gulf experiences dramatic spatial and temporal variations. The influence of the thermohaline forcing is considerably more than the wind stress on the salinity. The effect of the surface thermohaline fluxes over the salinity field is generally to increase the salinity for almost all the water column during the year. This effect is high during SeptemberNovember where the evaporative surface salinity flux dominates over inflow of low-salinity values of Indian Ocean Surface Water. The wind forcing at the most regions of the Persian Gulf, in particular at the United Arab Emirate (UAE) coast and BahrainQatar shelf, freshens the water all the year round. The wind and thermohaline forcing in MarchJune have strong potential to generate stratification in salinity structure. The model predictions, which are successful in simulating many features of observed pattern, indicate that the surface water of the Gulf is saltier in winter than that in spring and early summer. Both heat fluxes and wind stress play an important role for this seasonal cycle of the surface salinity.

Stellite 6 Friction Changes Due to Aging and In-Service Testing  

SciTech Connect

For the past several years, researchers at the Idaho National Engineering and Environmental Laboratory, under the sponsorship of the U.S. Nuclear Regulatory Commission, have been investigating the ability of motor-operated valves to close or open when subjected to design basis flow and pressure loads. Part of this research addresses the friction that occurs at the interface between the valve disc and the valve body seats during operation of a gate valve. In most gate valves, these surfaces are hardfaced with Stellite 6, a cobalt-based alloy. The nuclear industry has developed methods to analytically predict the thrust needed to operate these valves at specific pressure conditions. To produce accurate valve thrust predictions; the analyst must have a reasonably accurate, though conservative, estimate of the coefficient of friction at the disc-to-seat interface. One of the questions that remains to be answered is whether, and to what extent, aging of the disc and seat surfaces affects the disc-to-seat coefficient of friction. Specifically, does the accumulation of a surface film due to aging of these surfaces increase the coefficient of friction and if so, how much? This paper presents results of specimen tests addressing this issue with emphasis on the following: The change in the friction coefficient of Stellite 6 as it ages and whether the friction reaches a plateau. The effect periodic gate valve cycling due to in-service testing has on the friction coefficient. The results of an independent review of the test methods, processes, and the results of the research to date. The status of ongoing aging and friction testing.

A weak acceleration effect due to residual gravity in a multiply connected universe  

E-Print Network (OSTI)

Could cosmic topology imply dark energy? We use a weak field (Newtonian) approximation of gravity and consider the gravitational effect from distant, multiple copies of a large, collapsed (virialised) object today (i.e. a massive galaxy cluster), taking into account the finite propagation speed of gravity, in a flat, multiply connected universe, and assume that due to a prior epoch of fast expansion (e.g. inflation), the gravitational effect of the distant copies is felt locally, from beyond the naively calculated horizon. We find that for a universe with a $T^1xR^2$ spatial section, the residual Newtonian gravitational force (to first order) provides an anisotropic effect that repels test particles from the cluster in the compact direction, in a way algebraically similar to that of dark energy. For a typical test object at comoving distance $\\chi$ from the nearest dense nodes of the cosmic web of density perturbations, the pressure-to-density ratio $w$ of the equation of state in an FLRW universe, is w \\sim - (\\chi/L)^3, where $L$ is the size of the fundamental domain, i.e. of the universe. Clearly, |w|dark energy, but the amplitude of the effect at the present epoch is too small to explain the observed dark energy density and its anisotropy makes it an unrealistic candidate for the observed dark energy.

Physical property changes in hydrate-bearingsediment due to depressurization and subsequent repressurization  

SciTech Connect

Physical property measurements of sediment cores containing natural gas hydrate are typically performed on material exposed at least briefly to non-in situ conditions during recovery. To examine effects of a brief excursion from the gas-hydrate stability field, as can occur when pressure cores are transferred to pressurized storage vessels, we measured physical properties on laboratory-formed sand packs containing methane hydrate and methane pore gas. After depressurizing samples to atmospheric pressure, we repressurized them into the methane-hydrate stability field and remeasured their physical properties. Thermal conductivity, shear strength, acoustic compressional and shear wave amplitudes and speeds are compared between the original and depressurized/repressurized samples. X-ray computed tomography (CT) images track how the gas-hydrate distribution changes in the hydrate-cemented sands due to the depressurization/repressurization process. Because depressurization-induced property changes can be substantial and are not easily predicted, particularly in water-saturated, hydrate-bearing sediment, maintaining pressure and temperature conditions throughout the core recovery and measurement process is critical for using laboratory measurements to estimate in situ properties.

A Thoracic Mechanism of Mild Traumatic Brain Injury Due to Blast Pressure Waves  

E-Print Network (OSTI)

The mechanisms by which blast pressure waves cause mild to moderate traumatic brain injury (mTBI) are an open question. Possibilities include acceleration of the head, direct passage of the blast wave via the cranium, and propagation of the blast wave to the brain via a thoracic mechanism. The hypothesis that the blast pressure wave reaches the brain via a thoracic mechanism is considered in light of ballistic and blast pressure wave research. Ballistic pressure waves, caused by penetrating ballistic projectiles or ballistic impacts to body armor, can only reach the brain via an internal mechanism and have been shown to cause cerebral effects. Similar effects have been documented when a blast pressure wave has been applied to the whole body or focused on the thorax in animal models. While vagotomy reduces apnea and bradycardia due to ballistic or blast pressure waves, it does not eliminate neural damage in the brain, suggesting that the pressure wave directly affects the brain cells via a thoracic mechanism. ...

Enhancement of fusion rates due to quantum effects in the particles momentum distribution in nonideal media  

E-Print Network (OSTI)

This study concerns a situation when measurements of the nonresonant cross-section of nuclear reactions appear highly dependent on the environment in which the particles interact. An appealing example discussed in the paper is the interaction of a deuteron beam with a target of deuterated metal Ta. In these experiments, the reaction cross section for d(d,p)t was shown to be orders of magnitude greater than what the conventional model predicts for the low-energy particles. In this paper we take into account the influence of quantum effects due to the Heisenberg uncertainty principle for particles in a non-ideal medium elastically interacting with the medium particles. In order to calculate the nuclear reaction rate in the non-ideal environment we apply both the Monte Carlo technique and approximate analytical calculation of the Feynman diagram using nonrelativistic kinetic Green's functions in the medium which correspond to the generalized energy and momentum distribution functions of interacting particles. We show a possibility to reduce the 12-fold integral corresponding to this diagram to a fivefold integral. This can significantly speed up the computation and control accuracy. Our calculations show that quantum effects significantly influence reaction rates such as p +7Be, 3He +4He, p +7Li, and 12C +12C. The new reaction rates may be much higher than the classical ones for the interior of the Sun and supernova stars. The possibility to observe the theoretical predictions under laboratory conditions is discussed.

Discrimination of gamma rays due to inelastic neutron scattering in AGATA  

E-Print Network (OSTI)

Possibilities of discriminating neutrons and gamma rays in the AGATA gamma-ray tracking spectrometer have been investigated with the aim of reducing the background due to inelastic scattering of neutrons in the high-purity germanium crystals. This background may become a serious problem especially in experiments with neutron-rich radioactive ion beams. Simulations using the Geant4 toolkit and a tracking program based on the forward tracking algorithm were carried out by emitting neutrons and gamma rays from the center of AGATA. Three different methods were developed and tested in order to find 'fingerprints' of the neutron interaction points in the detectors. In a simulation with simultaneous emission of six neutrons with energies in the range 1-5 MeV and ten gamma rays with energies between 150 and 1450 keV, the peak-to-background ratio at a gamma-ray energy of 1.0 MeV was improved by a factor of 2.4 after neutron rejection with a reduction of the photopeak efficiency at 1.0 MeV of only a factor of 1.25.

Vibration and rattle impact due to low frequency noise investigated at Dulles airport  

Science Journals Connector (OSTI)

A noise study was conducted at Washington Dulles International Airport to further investigate the noise and vibration impact of thrust reversers and start of takeoff roll on communities near runways. Two different houses located on the airport property were instrumented with outdoor and indoor microphones and accelerometers mounted inside on walls windows and floor. This presentation will discuss both the experimental design and data obtained from the two different structures. Correlations between plane types outdoor signatures and acceleration levels are considered. The outdoor signatures and acceleration levels are used to investigate the conditions under which rattle of a loosely coupled window is observed. Additionally the design of a subsequent subjective study to examine the effects of rattle on human perception will be discussed. The combination of the objective measurements with the results of the subjective study is intended to give a better understanding of community impact due to airport noise.

An opposite view data replacement approach for reducing artifacts due to metallic dental objects  

SciTech Connect

Purpose: To present a conceptually new method for metal artifact reduction (MAR) that can be used on patients with multiple objects within the scan plane that are also of small sized along the longitudinal (scanning) direction, such as dental fillings. Methods: The proposed algorithm, named opposite view replacement, achieves MAR by first detecting the projection data affected by metal objects and then replacing the affected projections by the corresponding opposite view projections, which are not affected by metal objects. The authors also applied a fading process to avoid producing any discontinuities in the boundary of the affected projection areas in the sinogram. A skull phantom with and without a variety of dental metal inserts was made to extract the performance metric of the algorithm. A head and neck case, typical of IMRT planning, was also tested. Results: The reconstructed CT images based on this new replacement scheme show a significant improvement in image quality for patients with metallic dental objects compared to the MAR algorithms based on the interpolation scheme. For the phantom, the authors showed that the artifact reduction algorithm can efficiently recover the CT numbers in the area next to the metallic objects. Conclusions: The authors presented a new and efficient method for artifact reduction due to multiple small metallic objects. The obtained results from phantoms and clinical cases fully validate the proposed approach.

Risk assessment of loss of structural integrity of a floating production platform due to gross errors  

Science Journals Connector (OSTI)

During the last years The Norwegian Petroleum Directorate, as well as Statoil, has put increased focus on how gross errors related to structural integrity are influencing the safety of offshore installations. Also, the loss of the P36, a floating platform outside Brazil in 2001, emphasised the importance to control gross errors in large projects. On this basis, a work to assess the risk of loss of the structural integrity of the Kristin platform, during operation, due to failure from gross errors was initiated. The Kristin platform is a permanently moored ring-pontoon semi-submersible production unit planned to be placed in the south-west part of Haltenbanken area in the North Sea in 2005. The water depth at the site is approximately 315m. The objective of this work was to quantify the risk contribution from gross errors related to structural integrity and to pinpoint the most critical items that may govern the probability of gross error for the Kristin platform. Some of the main findings from this work are presented in this paper.

Unusual refinery boiler tube failures due to corrosion by sulfuric acid induced by steam leaks  

SciTech Connect

Corrosion by sulfuric acid in boilers is a low probability event because gas temperature and metal temperature of boiler tubes are high enough to avoid the condensation of sulfuric acid from flue gases. This degradation mechanism is frequently considered as an important cause of air preheaters materials degradation, where flue gases are cooled by heat transfer to the combustion air. Corrosion is associated to the presence of sulfuric acid, which condensates if metal temperature (or gas temperature) is below of the acid dew point. In economizer tubes, sulfuric acid corrosion is an unlikely event because flue gas and tube temperatures are normally over the acid dewpoint. In this paper, the failure analysis of generator tubes (similar to the economizer of bigger boilers) of two small oil-fired subcritical boilers is reported. It is concluded that sulfuric acid corrosion was the cause of the failure. The sulfuric acid condensation was due to the contact of flue gases containing SO{sub 3} with water-steam spray coming from leaks at the interface of rolled tube to the drum. Considering the information gathered from these two cases studied, an analysis of this failure mechanism is presented including a description of the thermodynamics condition of water leaking from the drum, and an analysis of the factors favoring it.

Observations of proton beam enhancement due to erbium hydride on gold foil targets  

SciTech Connect

Recent theoretical work suggests that the conversion efficiency from laser to protons in laser irradiated thin foil experiments increases if the atomic mass of nonhydrogen atoms on the foil rear surface increases. Experiments were performed at the Lawrence Livermore National Laboratory Jupiter Laser Facility to observe the effect of thin foils coated with erbium hydride on the conversion efficiency from laser to protons. Gold foils with and without the rear surface coated with ErH{sub 3} were irradiated using the ultrashort pulse, 40 TW Callisto laser. An argon-ion etching system was used to remove naturally occurring nanometer thick surface layer contaminants from the hydride. With the etcher, gold with ErH{sub 3} showed a 25% increase in the conversion efficiency to protons above 3.4 MeV relative to contaminants, where C{sup +4} and H{sup +} were the dominant ion species. No difference in the ion signal was observed without first cleaning the hydrides. Simulations using the hybrid PIC code, LSP, revealed that the increase due to erbium hydride versus contaminants is 37% for protons above 3 MeV.

Degradation of the mechanical properties of Zircaloy-4 due to hydrogen embrittlement  

Science Journals Connector (OSTI)

During nuclear reactor operation, the embrittlement of components made of zirconium-based alloys is observed. The degradation of their mechanical properties is due to the combined effect of hydrogen absorption and the damage caused by neutron irradiation. In this work we studied the influence of hydrogen content on the fracture toughness of a Zircaloy-4 alloy. Compact tension (CT) specimens were obtained from a hot-rolled, annealed and finally cold-rolled material. The observed microstructure consisted of ?-Zr rounded grains with diameters of about 15 ?m. Selection of the tested material was guided by the need to perform experiments on samples with a texture equivalent to the cladding components of Candu-type nuclear reactors. The specimens were fatigue precracked and hydrogen charged before testing. Two different reactions were performed. Specimens with a final hydrogen content ranging from 10 to 400 ppm were obtained by electrochemical charging and those with a final concentration of up to 2000 ppm were charged by absorption under a gaseous atmosphere. In both cases, an homogeneous distribution of dissolved hydrogen and hydride phases was obtained. The dependence of the toughness on temperature and hydrogen content was measured on CT specimens. The analysis was performed in terms of J-integral and resistance curves.

Measurements of solar flux density distribution on a plane receiver due to a flat heliostat  

SciTech Connect

An experimental facility is designed and manufactured to measure the solar flux density distribution on a central flat receiver due to a single flat heliostat. The tracking mechanism of the heliostat is controlled by two stepping motors, one for tilt angle control and the other for azimuth angle control. A x-y traversing mechanism is also designed and mounted on a vertical central receiver plane, where the solar flux density is to be measured. A miniature solar sensor is mounted on the platform of the traversing mechanism, where it is used to measure the solar flux density distribution on the receiver surface. The sensor is connected to a data acquisition card in a host computer. The two stepping motors of the heliostat tracking mechanism and the two stepping motors of the traversing mechanism are all connected to a controller card in the same host computer. A software `TOWER` is prepared to let the heliostat track the sun, move the platform of the traversing mechanism to the points of a preselected grid, and to measure the solar flux density distribution on the receiver plane. Measurements are carried out using rectangular flat mirrors of different dimensions at several distances from the central receiver. Two types of images were identified on the receiver plane - namely, apparent (or visible) and mirror-reflected radiation images. Comparison between measurements and a mathematical model validates the mathematical model. 13 refs., 12 figs., 1 tab.

Periodic Flux Variability of Stars due to the Reflex Doppler Effect Induced by Planetary Companions  

E-Print Network (OSTI)

Upcoming space-based photometric satellites offer the possibility of detecting continuum flux variability at the micro-magnitude level. We show that the Doppler flux variability induced by the reflex motion of stars due to planetary companions has an amplitude of (3-alpha)K/c, where K is the reflex radial velocity amplitude and alpha is the logarithmic slope of source spectral flux in the observed frequency band. For many of the known close-in planetary systems with periods less than ~0.2 years, the periodic Doppler variability is of order a micromagnitude, and is significant relative to the variability caused by reflected light from the planetary companion. For companions with periods greater than ~0.2 years, the Doppler signal is larger than the reflected light signal. We show that the future photometric satellites should reach the sensitivity to detect this Doppler variability. In particular, the Kepler satellite should have the photon-noise sensitivity to detect at a signal-to-noise ratio > 5, all planets with minimum mass greater than 5 Jupiter masses, and periods less than 0.1 years around the 10,000 main-sequence stars with spectral types A through K and apparent magnitude V<12 in its field-of-view.

Runaway greenhouse effect on exomoons due to irradiation from hot, young giant planets  

E-Print Network (OSTI)

The Kepler space telescope has detected transits of objects as small as the Earth's Moon, and moons as small as 0.2 Earth masses can be detected in the Kepler data by transit timing and transit duration variations of their host planets. Such massive moons around giant planets in the stellar habitable zone (HZ) could serve as habitats for extraterrestrial life. We here assess the danger of exomoons to be in a runaway greenhouse (RG) state due to extensive heating from the planet. We apply pre-computed evolution tracks for giant planets to calculate the incident planetary radiation on the moon as a function of time. The total energy budget of stellar flux, illumination from the planet, and tidal heating in the satellite is compared to the critical flux for the moon to experience an RG effect. Irradiation from a 13-Jupiter-mass planet onto an Earth-sized moon at a distance of ten Jupiter radii can drive an RG state on the moon for about 200 Myr. If stellar illumination equivalent to that received by Earth from t...

Bose-glass phases of ultracold atoms due to cavity backaction  

E-Print Network (OSTI)

We determine the quantum ground-state properties of ultracold bosonic atoms interacting with the mode of a high-finesse resonator. The atoms are confined by an external optical lattice, whose period is incommensurate with the cavity mode wave length, and are driven by a transverse laser, which is resonant with the cavity mode. While for pointlike atoms photon scattering into the cavity is suppressed, for sufficiently strong lasers quantum fluctuations can support the build-up of an intracavity field, which in turn amplifies quantum fluctuations. The dynamics is described by a Bose-Hubbard model where the coefficients due to the cavity field depend on the atomic density at all lattice sites. Quantum Monte Carlo simulations and mean-field calculations show that for large parameter regions cavity backaction forces the atoms into clusters with a checkerboard density distribution. Here, the ground state lacks superfluidity and possesses finite compressibility, typical of a Bose-glass. This system constitutes a novel setting where quantum fluctuations give rise to effects usually associated with disorder.

Buoyancy driven flow in a hot water tank due to standby heat loss  

Science Journals Connector (OSTI)

Results of experimental and numerical investigations of thermal behavior in a vertical cylindrical hot water tank due to standby heat loss of the tank are presented. The effect of standby heat loss on temperature distribution in the tank is investigated experimentally on a slim 150l tank with a height to diameter ratio of 5. A tank with uniform temperatures and with thermal stratification is studied. A detailed computational fluid dynamics (CFD) model of the tank is developed to calculate the natural convection flow in the tank. The distribution of the heat loss coefficient for the different parts of the tank is measured by experiments and used as input to the CFD model. Water temperatures at different levels of the tank are measured and compared to CFD calculated temperatures. The investigations focus on validation of the CFD model and on understanding of the CFD calculations. The results show that the CFD model predicts satisfactorily water temperatures at different levels of the tank during cooling by standby heat loss. It is elucidated how the downward buoyancy driven flow along the tank wall is established by the heat loss from the tank sides and how the natural convection flow is influenced by water temperatures in the tank. When the temperature gradient in the tank is smaller than 2K/m, there is a downward fluid velocity of 0.0030.015m/s. With the presence of thermal stratification the buoyancy driven flow is significantly reduced. The dependence of the velocity magnitude of the downward flow on temperature gradient is not influenced by the tank volume and is only slightly influenced by the tank height to tank diameter ratio. Based on results of the CFD calculations, an equation is determined to calculate the magnitude of the buoyancy driven flow along the tank wall for a given temperature gradient in the tank.

High-Frequency Effect Due to the Axial Drift Velocity of a Plasma Column  

Science Journals Connector (OSTI)

The scattering of a plane electromagnetic wave with normal incidence (E field perpendicular to the axis) by a plasma column in the presence of a static magnetic induction B0 has been studied earlier. A heretofore unexplained effect, however, is the existence of a scattered axial field EZ even when B0=0. A mechanism responsible for this coupling between the EZ and the transverse E field, in the absence of B0, is investigated here, namely the role of an axial drift velocity vd. The effect observed is a resonance peak of EZ occurring at the same density for which there exists a resonance of the scattered transverse E field which is well explained by a uniform cold-plasma model. The same model is therefore assumed here. In this approximation the plasma can be described by a surface charge density ? due to the HF polarization which gives rise to a surface current density K=?vd. The boundary conditions then lead to the existence of an EZ which, for B0=0, has a sin? dependence when the exciting field has a cos? dependence. When B0?0, a more complicated theoretical spectrum is obtained. Both the position and the angular dependence of the resonances are in very good agreement with experimental data. The effect predicted by this model is, however, more than an order of magnitude below that observed in a mercury plasma column. This phenomenon can be described as the plasma radio-frequency analog of the static field induced by the Roentgen-Eichenwald current.

Measurement of building foundation and ground-borne vibrations due to surface trains and subways  

Science Journals Connector (OSTI)

Abstract Buildings located near surface trains and subways are subjected to surface train and subway-induced vibrations. Cutting edge technologies in laboratories and precision manufacturing facilities often include operation of vibration sensitive equipment. Human comfort in the form of feelable vibrations and audible noise in residential and office buildings is also a concern. It is thus imperative to reduce these vibrations inside buildings to acceptable levels with the design of an efficient vibration mitigation system. Incorporation of a vibration mitigation system in a building in design phase requires prior understanding and characterization of subway and surface train-induced base excitations of buildings before and after the construction of a structure to meet serviceability criteria. The vibrations measured at the foundation slab of buildings serve as the base excitation for the building and transmit to the to upper floor levels through columns. The focus of this paper is to quantify the amplitudes and frequency contents of vibration level measured at foundation slab and compare these vibration measurements inside the building at foundation level with the open field measurements. In this context, an exploration of ground-borne vibration characteristics was performed at six sites in the Boston area. Three sites were selected for measuring train-induced vibration and another three were considered for subway-induced vibration study. Vibration measurements were performed on the building foundation slab as well as in open fields adjacent to the building. These vibration measurements were quantified and compared. It was found that in the case of surface train-induced building vibrations, open field vibration levels can be conservatively used in the design of buildings. However due to inconsistency in observations, a similar conclusion was not drawn for the case of subway-induced building vibration. This paper also provides the bases that would allow the designer to estimate the vibration levels in sensitive locations within the building. These estimated levels determine the extent to which mitigation is required to meet vibration criteria.

EFFECT ON 105KW NORTH WALL DUE TO ADDITION OF FILTRATION SYSTEM  

SciTech Connect

CHPRC D&D Projects is adding three filtration system on two 1-ft concrete pads adjacent to the north side of existing KW Basin building. This analysis is prepared to provide qualitative assessment based on the review of design information available for 105KW basin substructure. In the proposed heating, ventilation and air conditioning (HVAC) filtration pad designs a 2 ft gap will be maintained between the pads and the north end of the existing 1 05KW -Basin building. Filtration Skids No.2 and No.3 share one pad. It is conservative to evaluate the No.2 and No.3 skid pad for the wall assessment. Figure 1 shows the plan layout of the 105KW basin site and the location of the pads for the filtration system or HVAC skids. Figure 2 shows the cross-section elevation view of the pad. The concrete pad Drawing H-1-91482 directs the replacement of the existing 8-inch concrete pad with two new 1-ft think pads. The existing 8-inch pad is separated from the 105KW basin superstructure by an expansion joint of only half an inch. The concrete pad Drawing H-1-91482 shows the gap between the new proposed pads and the north wall and any overflow pits and sumps is 2-ft. Following analysis demonstrates that the newly added filtration units and their pads do not exceed the structural capacity of existing wall. The calculation shows that the total bending moment on the north wall due to newly added filtration units and pads including seismic load is 82.636 ft-kip/ft and is within the capacity of wall which is 139.0ft-kip/ft.

Wolf-Rayet Mass-Loss Limits Due to Frequency Redistribution  

E-Print Network (OSTI)

The hypothesis that CAK-type line driving is responsible for the large observed Wolf-Rayet (W-R) mass-loss rates has been called into question in recent theoretical studies. The purpose of this paper is to reconsider the plausibility of line driving of W-R winds within the standard approach using the Sobolev approximation while advancing the conceptual understanding of this topic. Due to the multiple scattering required in this context, of particular importance is the role of photon frequency redistribution into spectral gaps, which in the extreme limit yields the statistical Sobolev-Rosseland (SSR) mean approximation. Interesting limits to constrain are the extremes of no frequency redistribution, wherein the small radii and corresponding high W-R surface temperature induces up to twice the mass-loss rate relative to cooler stars, and the SSR limit, whereby the reduced efficiency of the driving drops the mass flux by as much as an order of magnitude whenever there exist significant gaps in the spectral line distribution. To see how this efficiency drop might be sufficiently avoided to permit high W-R mass loss, we explore the suggestion that ionization stratification may serve to fill the gaps globally over the wind. We find that global ionization changes can only fill the gaps sufficiently to cause about a 25% increase in the mass-loss rate over the local SSR limit. Higher temperatures and more ionization states (especially of iron) may be needed to achieve optically thick W-R winds, unless strong clumping corrections eliminate the need for such winds.

Deviation of Stellar Orbits from Test Particle Trajectories around SgrA* Due to Tides and Winds  

Science Journals Connector (OSTI)

Monitoring the orbits of stars around SgrA* offers the possibility of detecting the precession of their orbital planes due to frame dragging, of measuring the spin and quadrupole moment of the black hole, and of testing the no-hair theorem. Here we investigate whether the deviations of stellar orbits from test-particle trajectories due to wind mass loss and tidal dissipation of the orbital energy compromise such measurements. We find that the effects of stellar winds are, in general, negligible. On the other hand, for the most eccentric orbits (e > 0.96) for which an optical interferometer, such as GRAVITY, will detect orbital plane precession due to frame dragging, the tidal dissipation of orbital energy occurs at timescales comparable to the timescale of precession due to the quadrupole moment of the black hole. As a result, this non-conservative effect is a potential source of systematic uncertainty in testing the no-hair theorem with stellar orbits.

Gravitational radiation and angular momentum flux from a slowly rotating dynamical black hole  

SciTech Connect

A four-dimensional asymptotic expansion scheme is used to study the next-order effects of the nonlinearity near a spinning dynamical black hole. The angular-momentum flux and energy flux formula are then obtained by constructing the reference frame in terms of the compatible constant spinors and the compatibility of the coupling leading-order Newman-Penrose equations. By using the slow rotation and small-tide approximation for a spinning black hole, the horizon cross-section we chose is spherical symmetric. It turns out the flux formula is rather simple and can be compared with the known results. Directly from the energy flux formula of the slow-rotating dynamical horizon, we find that the physically reasonable condition on requiring the positivity of the gravitational energy flux yields that the shear will monotonically decrease with time. Thus a slow-rotating dynamical horizon will asymptotically approach an isolated horizon during late time.

SLOWLY ROTATING GAS-RICH GALAXIES IN MODIFIED NEWTONIAN DYNAMICS (MOND)  

SciTech Connect

We have carried out a search for gas-rich dwarf galaxies that have lower rotation velocities in their outskirts than MOdified Newtonian Dynamics (MOND) predicts, so that the amplitude of their rotation curves cannot be fitted by arbitrarily increasing the mass-to-light ratio of the stellar component or by assuming additional undetected matter. With presently available data, the gas-rich galaxies UGC 4173, Holmberg II, ESO 245-G05, NGC 4861, and ESO 364-G029 deviate most from MOND predictions and, thereby, provide a sample of promising targets in testing the MOND framework. In the case of Holmberg II and NGC 4861, we find that their rotation curves are probably inconsistent with MOND, unless their inclinations and distances differ significantly from the nominal ones. The galaxy ESO 364-G029 is a promising target because its baryonic mass and rotation curve are similar to Holmberg II but presents a higher inclination. Deeper photometric and H I observations of ESO 364-G029, together with further decreasing systematic uncertainties, may provide a strong test to MOND.

An exact solution for the expansion of a flat universe with dark energy evolving according to a simple model is explored. The equation for weak primordial gravitational waves propagating in this universe is solved and explored; gravitational waves in a flat cosmology possessing both a "big bang" singularity and a "big rip" singularity can be described with confluent Heun functions. We develop approximation methods for confluent Heun equations in regimes of interest to gravitational wave astronomers and predict the diminution in gravitational wave amplitude in a universe with both a Big Bang and a Big Rip.

Comment on"Air Emissions Due to Wind and Solar Power" and Supporting Information  

SciTech Connect

Katzenstein and Apt investigate the important question of pollution emission reduction benefits from variable generation resources such as wind and solar. Their methodology, which couples an individual variable generator to a dedicated gas plant to produce a flat block of power is, however, inappropriate. For CO{sub 2}, the authors conclude that variable generators 'achieve {approx} 80% of the emission reductions expected if the power fluctuations caused no additional emissions.' They find even lower NO{sub x} emission reduction benefits with steam-injected gas turbines and a 2-4 times net increase in NO{sub x} emissions for systems with dry NO{sub x} control unless the ratio of energy from natural gas to variable plants is greater than 2:1. A more appropriate methodology, however, would find a significantly lower degradation of the emissions benefit than suggested by Katzenstein and Apt. As has been known for many years, models of large power system operations must take into account variable demand and the unit commitment and economic dispatch functions that are practiced every day by system operators. It is also well-known that every change in wind or solar power output does not need to be countered by an equal and opposite change in a dispatchable resource. The authors recognize that several of their assumptions to the contrary are incorrect and that their estimates therefore provide at best an upper bound to the emissions degradation caused by fluctuating output. Yet they still present the strong conclusion: 'Carbon dioxide emissions reductions are likely to be 75-80% of those presently assumed by policy makers. We have shown that the conventional method used to calculate emissions is inaccurate, particularly for NO{sub x} emissions.' The inherently problematic methodology used by the authors makes such strong conclusions suspect. Specifically, assuming that each variable plant requires a dedicated natural gas backup plant to create a flat block of power ignores the benefits of diversity. In real power systems, operators are required to balance only the net variations of all loads and all generators, not the output of individual loads or generators; doing otherwise would ensure an enormous amount of unnecessary investment and operating costs. As a result, detailed studies that aggregate the variability of all loads and generators to the system level find that the amount of operating reserves required to reliably integrate variable resources into the grid are on the order of 10% of the nameplate capacity of the variable generators, even when upto25%of gross demand is being met by variable generation. The authors implicit assumption that incremental operating reserves must be 100% of the nameplate capacity of the variable generation, and be available at all times to directly counter that variability, excludes the option of decommitting conventional units when the load net of variable generation is low. In real power systems, generation response to wind variation can typically be met by a combination of committed units, each operating at a relatively efficient point of their fuel curves. In the Supporting Information, we conceptually demonstrate that the CO{sub 2} and NO{sub x} efficiency penalty found by the authors can be significantly reduced by considering the unit commitment decision with just five plants. Real systems often have tens to hundreds of plants that can be committed and decommitted over various time frames. Ignoring the flexibility of the unit commitment decision therefore leads to unsupportable results. Anumber of analyses of the fuel savings and CO{sub 2} emission benefits of variable generation have considered realistic operating reserve requirements and unit commitment decisions in models that include the reduction in part load efficiency of conventional plants. The efficiency penalty due to the variability of wind in four studies considered by Gross et al. is negligible to 7%, for up to a 20% wind penetration level. In short, for moderate wind penetration levels, 'there is no evidence available to

Multi-GeV neutrinos due to neutro anti-neutron oscillation in Gamma-Ray Burst Fireballs  

E-Print Network (OSTI)

The long and short gamma-ray bursts are believed to be produced due to collapse of massive stars and merger of compact binaries respectively. All these objects are rich in neutron and the jet outflow from these objects must have a neutron component in it. By postulating the neutron anti-neutron oscillation in the gamma-ray burst fireball, we show that, 19-38 GeV neutrinos and anti-neutrinos can be produced due to annihilation of anti-neutrons with the background neutrons. These neutrinos and anti-neutrinos will be produced before the 5-10 GeV neutrinos due to dynamical decoupling of neutrons from the rest of the fireball. Observation of these neutrinos will shed more light on the nature of the GRB progenitors and also be a unique signature of physics beyond the standard model. A possible way of detecting these neutrinos in future is also discussed.

The pressure distribution is an important aspect of a UHV subsystem in either a storage ring or a front end. The design of the 3-GeV, 400-mA Taiwan Photon Source (TPS) foresees outgassing induced by photons and due to a bending magnet and an insertion device. An algorithm to calculate the photon-stimulated absorption (PSD) due to highly energetic radiation from a synchrotron source is presented. Several results using undulator sources such as IU20 are also presented, and the pressure distribution is illustrated.

Effects of eddy currents due to a vacuum chamber wall in the airgap of a moving-magnet linear actuator  

SciTech Connect

This paper discusses the effects of eddy currents induced in an electrically conducting plate which is placed in the airgap of a linear synchronous actuator with moving permanent magnets. The eddy currents induced in this plate, which is part of a controlled atmosphere chamber, cause not only damping but also deteriorate the actuator performance by disturbing the position measurement with Hall sensors. Furthermore, feed-forward controllers are less effective due to the suppression of high frequent armature fields. These effects are analyzed with an analytical model and verified with finite element simulations and measurements.

These new findings as well as the relation between ion-confining potentials and thermal-barrier potentials in the kV range consistently support the validity of Cohens strong ECH theory.

Science Journals Connector (OSTI)

Abstract A numerical framework was developed for estimating the life-cycle monetary losses (maintenance and repair costs) due to wind-induced damage on a long-span bridge. The wind loading on the bridge deck was evaluated by means of flutter derivatives (FDs), which are measured in a wind tunnel test on a section-model of the deck. These aeroelastic coefficients are random due to experimental errors. A statistical approach was employed to evaluate the effects of this uncertainty source on the wind-induced response and the damage produced on the structure. In the first part of the study fragility curves and surfaces were used to estimate the exceedance probability of representative structural performance threshold indicators by accounting for experimental errors in the estimation of FDs. These thresholds were based on deck acceleration (for user comfort) and peak deck displacements (for structural damage). In the second part the results of the initial fragility analysis were used to analyze monetary losses, produced by wind loading. The proposed model for cost analysis was adapted from an existing life-cycle simulation algorithm for earthquake hazards. The pilot study employs a 1200-m suspension bridge model and data from wind tunnel experiments conducted at Northeastern University in the United States.

Finite element modeling of the temperature rise due to the propagation of ultrasonic waves in viscoelastic materials and experimental validation  

Science Journals Connector (OSTI)

The ultrasound stimulated thermography method is usually used to detect the temperature rise at a defect position. The temperature rise can be due to the friction between the edges of the defect and/or the plastic deformation around the defect. This paper presents another aspect of the method when the ultrasounds are propagating in a viscoelasticanisotropicmaterial such as polymers or fiber-reinforced polymers. The attenuation of the waves produces a distributed temperature field. Therefore even a defect that does not produce some heat can be detected the ultrasonic field is modified. A finite element model is used for computing the temperature field and for predicting the possibility for an infrared camera of detecting the temperature rise and its modification due to a defect. The model computes the stress and displacement fields associated with the propagation and the loss of energy. Then the heat equation is solved with this loss as a source of heating. An experiment is done with a sonotrode that excites a PVC plate. The ultrasonic displacement at the top of the plate is measured with a laser velocimeter and introduced in the model. Finally the model result is compared to the image produced by the camera.

Predicting underwater radiated noise levels due to the first offshore wind turbine installation in the United States  

Science Journals Connector (OSTI)

Noise generated by offshore impact pile driving radiates into the air water and sediment. Predicting noise levels around the support structures at sea is required to estimate the effects of the noise on marine life. Based on high demands developing renewable energy source the United States will begin the first pile driving within one to two years. It is necessary to investigate acoustic impact using our previously verified coupled Finite Element (Commercial FE code Abaqus) and Monterey Miami Parabolic Equation (2D MMPE) models [J. Acoust. Soc. Am. 131(4) 3392 (2012)]. In the present study we developed a new coupled FE-MMPE model for the identification of zone of injury due to offshore impact pile driving. FE analysis produced acoustic pressure outputs on the surface of the pile which are used as a starting field for a long range 2D MMPE propagation model. It calculates transmission loss for N different azimuthal directions as function of distance from the location of piling with the inputs of corresponding bathymetry and sediment properties. We will present predicted zone of injury by connecting N different distances of equivalent level fishes may get permanent injury due to the first offshore wind farm installation in the United States.

Effects of supplemental UV-B radiation on the growth and yield of two cultivars of Japanese lowland rice (Oryza sativa L.) under the field in a cool rice-growing region of Japan  

Science Journals Connector (OSTI)

An investigation was made of the variations in growth and grain yield in response to increased exposure to UV-B radiation of Japanese lowland rice (Oryza sativa L.) in a cool rice-growing region. Two cultivars, UV-resistant cv. Sasanishiki and UV-sensitive cv. Norin 1, were examined in a lowland field at Kashimadai (3728?E, 14106?E) in Miyagi Prefecture, Japan, for four cropping seasons from 1994 to 1997. The two cultivars were grown in a lowland field with or without supplemental UV-B radiation, which was provided by UV-B-emitting fluorescent lamps, with a 0.1-mm-thick cellulose diacetate film as a filter. In both cultivars, significant decreases in tiller number as the result of supplemental UV-B radiation were observed during the tillering stage in 1994, 1995 and 1997. Furthermore, decreases in grain size from supplemental UV-B radiation were recorded in all seasons. The trend towards small grain size was pronounced in 1996. In that year, the mean daily middle temperatures were lower throughout most of the cropping season and the mean daily hours of sunshine during the tillering stage and between the end of the panicle differentiation stage and the beginning of the ripening stage were shorter. In 1993 when the temperature and the amount of sunshine were both lower, the tiller number, the dry mass of aboveground parts and the panicle number were significantly reduced by supplemental unfiltered UV-B radiation. There was a cultivar difference in the inhibitory effects of supplemental UV-B radiation on growth between the sensitive cultivar Norin 1 and the resistant cultivar Sasanishiki. These results indicate that supplemental UV-B radiation has a positive effect on the growth and grain development of rice, which may be enhanced by unusual climatic conditions such as lower temperature and less sunshine, in cool rice-growing regions.

Mine operators look for more throughput with less fines generation in primary crushers (defined here as single role crushers and two stage crushers). The article gives advice on crusher selection and application. Some factors dictating selection include the desired product size, capacity, Hard Grove grindability index, percentage of rock to be freed and hardness of that rock. The hardness of coal probably has greatest impact on product fineness. 2 refs., 1 fig., 1 tab.

Silviculture: growing more wood on less land  

SciTech Connect

Maximizing the production of a concentrated, homogeneous wood supply virtually dictates intensively managed plantations. This management system implies: (1) improving the composite genotype of plantation trees; (2) optimizing their morphological and physiological condition prior to and at planting time; (3) improving the physiological environment of the crop at all stages of development; (4) protecting the plantation from pests and catastrophic events; and (5) modifying the shapes, dimensions, and qualities of crop trees to enhance the utility and value of harvested timber. Beneficiation of forest residuals for fiber and fuel is pushing forest industry relentlessly toward total stand utilization. Relative to the productivity of undisturbed or partially logged humid tropical forests, plantation growth rates represent four-fold to ten-fold increases in volume production. Displacement of some proportion of shifting agriculture and natural forest management systems by intensively managed plantations is desirable and biologically feasible. A key to successful tropical forest management and preservation is population stability, a condition toward which integrated wood conversion facilities supplied by a reliable plantation system can make a major contribution. There are some pressing and many esoteric reasons for conserving forest resources but pressures for utilizing and renewing these resources are immediate and unavoidable.

Ignition of Deflagration and Detonation Ahead of the Flame due to Radiative Preheating of Suspended Micro Particles  

E-Print Network (OSTI)

We study a flame propagating in the gaseous combustible mixture with suspended inert solid micro particles. The gaseous mixture is assumed to be transparent for thermal radiation emitted by the hot combustion products, while particles absorb and reemit the radiation. Thermal radiation heats the particles, which in turn transfer the heat to the surrounding unburned gaseous mixture by means of thermal heat transfer. Different scenarios are possible depending on the spatial distribution of the particles, their size and the number density. In the case of uniform spatial distribution the radiation absorption ahead of the flame causes a modest increase of the combustion wave velocity. On the contrary, in the case of non-uniform distribution of the particles, such that the particles number density increases far ahead of the flame, the preheating caused by the thermal radiation may trigger additional source of ignition. Far enough ahead of the flame, where number density of particles is higher, the temperature due to...

Magnetic Field Decay Due to the Wave-Particle Resonances in the Outer Crust of the Neutron Star  

E-Print Network (OSTI)

Bearing in mind the application to the outer crust of the neutron stars (NSs), we investigate the magnetic field decay by means of the fully relativistic Particle-In-Cell simulations. Numerical computations are carried out in 2-dimensions, in which the initial magnetic fields are set to be composed both of the uniform magnetic fields that model the global fields penetrating the NS and of the turbulent magnetic fields that would be originated from the Hall cascade of the large-scale turbulence. Our results show that the whistler cascade of the turbulence transports the magnetic energy preferentially in the direction perpendicular to the uniform magnetic fields. It is also found that the distribution function of electrons becomes anisotropic because electrons with lower energies are predominantly heated in the direction parallel to the uniform magnetic fields due to the Landau resonance, while electrons with higher energies are heated mainly by the cyclotron resonance that makes the distribution function isotro...

Observation of FowlerNordheim hole tunneling across an electron tunnel junction due to total symmetry filtering  

Science Journals Connector (OSTI)

Using a SrTiO3(001) barrier and La0.7Sr0.3MnO3(001) electrodes, we study the case of coherent spin-polarized tunneling of electrons that exhibit a symmetry mismatch with respect to the lower electron barrier height. Due to this mismatch, electrons with energy above this barrier height continue to tunnel thanks to total symmetry filtering. This allows us to observe symmetry-matched hole tunneling across this electron tunnel junction, and in particular spin-polarized oscillations in the Fowler-Nordheim hole regime above the hole barrier height, thereby enriching the present theoretical picture of coherent spin-polarized tunneling at finite bias.
