Femtoscopy in Relativistic Heavy Ion Collisions: Two Decades of Progress  

E-Print Network (OSTI)

Analyses of two-particle correlations have provided the chief means for determining spatio-temporal characteristics of relativistic heavy ion collisions. We discuss the theoretical formalism behind these studies and the experimental methods used in carrying them out. Recent results from RHIC are put into context in a systematic review of correlation measurements performed over the past two decades. The current understanding of these results is discussed in terms of model comparisons and overall trends.

The recycling rate of atmospheric moisture over the past two decades (1988–2009)  

Science Journals Connector (OSTI)

Numerical models predict that the recycling rate of atmospheric moisture decreases with time at the global scale, in response to global warming. A recent observational study (Wentz et al 2007 Science 317 233–5) did not agree with the results from numerical models. Here, we examine the recycling rate by using the latest data sets for precipitation and water vapor, and suggest a consistent view of the global recycling rate of atmospheric moisture between numerical models and observations. Our analyses show that the recycling rate of atmospheric moisture has also decreased over the global oceans during the past two decades. In addition, we find different temporal variations of the recycling rate in different regions when exploring the spatial pattern of the recycling rate. In particular, the recycling rate has increased in the high-precipitation region around the equator (i.e., the intertropical convergence zone) and decreased in the low-precipitation region located either side of the equator over the past two decades. Further exploration suggests that the temporal variation of precipitation is stronger than that of water vapor, which results in the positive trend of the recycling rate in the high-precipitation region and the negative trend of the recycling rate in the low-precipitation region.

A Prototype Two-Decade Fully-Coupled Fine-Resolution CCSM Simulation  

SciTech Connect

A fully coupled global simulation using the Community Climate System Model (CCSM) was configured using grid resolutions of 0.1{sup o} for the ocean and sea-ice, and 0.25{sup o} for the atmosphere and land, and was run under present-day greenhouse gas conditions for 20 years. It represents one of the first efforts to simulate the planetary system at such high horizontal resolution. The climatology of the circulation of the atmosphere and the upper ocean were compared with observational data and reanalysis products to identify persistent mean climate biases. Intensified and contracted polar vortices, and too cold sea surface temperatures (SSTs) in the subpolar and mid-latitude Northern Hemisphere were the dominant biases produced by the model. Intense category 4 cyclones formed spontaneously in the tropical North Pacific. A case study of the ocean response to one such event shows the realistic formation of a cold SST wake, mixed layer deepening, and warming below the mixed layer. Too many tropical cyclones formed in the North Pacific however, due to too high SSTs in the tropical eastern Pacific. In the North Atlantic anomalously low SSTs lead to a dearth of hurricanes. Agulhas eddy pathways are more realistic than in equivalent stand-alone ocean simulations forced with atmospheric reanalysis.

The underlying causes of global warming are well enough understood, but the necessary reduction of greenhouse gases to prevent irreversible climate change is unlikely to happen before the point of no return is reached. To reverse the impending sea level rise, geoengineering counter- measures may be required to counter the current global energy imbalance due to global warming. Of the many proposed remedies, deploying aerosols within the stratosphere offers realistic prospects.

Reversible and coherent storage of light in atomic medium is a key-stone of future quantum information applications. In this work, arbitrary two-dimensional images are slowed and stored in warm atomic vapor for up to 30 $\\mu$s, utilizing electromagnetically induced transparency. Both the intensity and the phase patterns of the optical field are maintained. The main limitation on the storage resolution and duration is found to be the diffusion of atoms. A techniqueanalogous to phase-shift lithography is employed to diminish the effect of diffusion on the visibility of the reconstructed image.

Future-oriented women will pay to reduce global warming: Mediation via political orientation, environmental values, and belief in global warming  

Science Journals Connector (OSTI)

Abstract The present work addresses calls to clarify the role of gender in climate change mitigation and adaptation by testing a theoretical model linking gender and concern with future and immediate consequences to mitigation actions through political orientation, environmental values, and belief in global warming (gender × time orientation ? liberal political orientation ? environmental values ? belief in global warming ? willingness to pay to reduce global warming). Drawing on a sample of 299 U.S. residents, structural equation modeling and bootstrapped indirect effects testing revealed support for the model. Interaction analyses further revealed that women scored higher than men on model variables among respondents who routinely consider the future consequences of their actions, but the gender difference was reversed among those low in concern with future consequences (on liberal political orientation and willingness to pay to reduce global warming). Practical and theoretical implications are considered.

Cosmic Rays and Global Warming  

E-Print Network (OSTI)

It has been claimed by others that observed temporal correlations of terrestrial cloud cover with `the cosmic ray intensity' are causal. The possibility arises, therefore, of a connection between cosmic rays and Global Warming. If true, the implications would be very great. We have examined this claim to look for evidence to corroborate it. So far we have not found any and so our tentative conclusions are to doubt it. Such correlations as appear are more likely to be due to the small variations in solar irradiance, which, of course, correlate with cosmic rays. We estimate that less than 15% of the 11-year cycle warming variations are due to cosmic rays and less than 2% of the warming over the last 35 years is due to this cause.

5 - Consequences of Global Warming  

Science Journals Connector (OSTI)

Abstract This chapter looks at different areas of risk associated with the onset of global warming. The first risk area refers to pathogens and diseases. We first discuss perspectives on disease spread, and focus on the role played by globalization and the current livestock “revolution” strongly affected by large-scale processes of urbanization. We then discuss zoonoses, or diseases that are passed between humans and other animals, and identify 11 kinds of zoonoses associated with global warming. Although not a zoonose, malaria is also discussed. Patterns of transmission associated with warming tend to be poleward, and small changes in temperature can produce large changes in disease vectors to higher latitudes. A brief presentation of the history of malaria shows how it has had a substantial effect on conflicts in the past, particularly the US Civil War (1861–1865) and World War I. It has been famously suggested that World War I ended because of the spread of Swine Flu, decimating the Axis troops and rendering many units unable to continue fighting. AIDS is presented as a contemporary example of the way in which diseases can profoundly undermine the capacity of a country to provide security and state leadership, and undercut international peacekeeping activities.

Net carbon uptake has increased through warming-induced changes in temperate forest phenology  

SciTech Connect

The timing of phenological events exerts a strong control over ecosystem function and leads to multiple feedbacks to the climate system1. Phenology is inherently sensitive to temperature (though the exact sensitivity is disputed2) and recent warming is reported to have led to earlier spring, later autumn3,4 and increased vegetation activity5,6. Such greening could be expected to enhance ecosystem carbon uptake7,8, though reports also suggest decreased uptake for boreal forests4,9. Here we assess changes in phenology of temperate forests over the eastern US during the past two decades, and quantify the resulting changes in forest carbon storage. We combine long-term ground observations of phenology, satellite indices, and ecosystem-scale carbon dioxide flux measurements, along with 18 terrestrial biosphere models. We observe a strong trend of earlier spring and later autumn. In contrast to previous suggestions4,9 we show that carbon uptake through photosynthesis increased considerably more than carbon release through respiration for both an earlier spring and later autumn. The terrestrial biosphere models tested misrepresent the temperature sensitivity of phenology, and thus the effect on carbon uptake. Our analysis of the temperature-phenology-carbon coupling suggests a current and possible future enhancement of forest carbon uptake due to changes in phenology. This constitutes a negative feedback to climate change, and is serving to slow the rate of warming.

2 - What Is Global Warming?  

Science Journals Connector (OSTI)

Abstract In this chapter, we introduce students to the basic notion of global warming. We begin with a discussion of the historical ordinariness of global temperature swings, reviewing patterns of temperature changes across glaciations in the most recent glacial period. This is followed by a discussion of the nature of greenhouse gases, how they heat the planet, and the centrality of CO2 in the production of weather. The earth’s energy budget is presented as a chart that illustrates how various elements of the planet and its atmosphere interact to arrive at average temperatures. Following this is a discussion of human-created sources of greenhouse gases heating the planet, and here we introduce the concept of climate forcings, or external variables that are responsible for causing global temperature increases (or decreases). Primary and secondary feedbacks are shown as mechanisms in which warming, once it reaches a certain level, tends to become self-fulfilling, increasing the rate and level of heating beyond human capacity to intervene. Critical tipping points, or points at which fundamental changes in the climate will occur, are followed by a discussion of climate sensitivity, which is the assessment of the amount of temperature increase associated with increments of greenhouse gases. Finally, we ask “how hot will it get,” and close with a discussion of overall heating capacity for short- and long-term periods and a discussion of the duration of greenhouse gases, once introduced into the atmosphere.

Reversible collisionless magnetic reconnection  

SciTech Connect

Reversible magnetic reconnection is demonstrated for the first time by means of gyrokinetic numerical simulations of a collisionless magnetized plasma. Growth of a current-driven instability in a sheared magnetic field is accompanied by magnetic reconnection due to electron inertia effects. Following the instability growth, the collisionless reconnection is accelerated with development of a cross-shaped structure of current density, and then all field lines are reconnected. The fully reconnected state is followed by the secondary reconnection resulting in a weakly turbulent state. A time-reversed simulation starting from the turbulent state manifests that the collisionless reconnection process proceeds inversely leading to the initial state. During the reversed reconnection, the kinetic energy is reconverted into the original magnetic field energy. In order to understand the stability of reversed process, an external perturbation is added to the fully reconnected state, and it is found that the accelerated reconnection is reversible when the deviation of the E × B streamlines due to the perturbation is comparable with or smaller than a current layer width.

Innovation and the dynamics of global warming  

Science Journals Connector (OSTI)

Abstract Global warming and the carbon cycle are a dynamic system with positive feedbacks. Fossil fuels are exhaustible resources. These two facts mean that innovation in clean energy technology, rather than mitigating global warming, can lead to a permanently higher temperature path. This paper explores the impact of innovation in the simplest model linking the economic theory of exhaustible resources with positive feedback dynamics in the carbon cycle.

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

Cold-blooded and warm-blooded Cold-blooded and warm-blooded Name: Walter Status: N/A Age: N/A Location: N/A Country: N/A Date: Around 1993 Question: What is the fundamental difference between cold-blooded and warm- blooded creatures? I know that reptile blood is a bit different than mammal blood, but is that the difference or is it a difference in the other cells of the body? Replies: Warm blooded refers to an animals ability to maintain its body temperature at a constant level. Cold blooded animal's bodies stay at the temperature of environment around them (more or less). The mechanism by which a warm blooded animal does this is by generating heat, mostly through muscle movement (but by other biochemical processes too). An example of this is shivering. Warm blooded animals also cool themselves off by sweating, panting (and other ways). In mammals the hypothalamic area of the brain has much to do with controlling these reflex processes

1 - The Challenges of Global Warming Research  

Science Journals Connector (OSTI)

Abstract This chapter focuses on two items. First, it addresses the issue of global warming in a hostile political environment. Second, it looks at what might be called the basic research element connecting global warming to crime: research on the relationship between crime and weather. The first item addresses the nature of research itself—how do we recognize when research is any good? There is a great deal of bad and misleading research on global warming. How do we know which is bad and which is good? The chapter begins with a discussion of three articles on Greenland melt-off, each with quite different implications, and discusses how to tell which is a legitimate research summary and which is not. It then provides a discussion of what constitutes good research generally and what one should look for when research is poorly done or intentionally misleading. For the second item, global warming and crime, we begin with a discussion of the difference between climate and weather. Much of this section is a review of Cohn’s work on temperature, crime, and violent crime. We also discuss the Ranson model, which provides a good description of the way in which crime can be modeled and predicted using data and research methods derived from the global warming literature.

Ultrafast Spectroscopy of Warm Dense Matter  

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

Ultrafast Spectroscopy of Warm Dense Matter Print Ultrafast Spectroscopy of Warm Dense Matter Print Being neither solid, liquid, gas, nor plasma, warm dense matter (WDM) occupies a no man's land in the map of material phases. Its temperature can range between that of planetary cores (tens of thousands K) to that of stellar cores (hundreds of thousands K). Not only is it prevalent throughout the universe, it is relevant to inertial confinement fusion (ICF) and material performance under extreme conditions. However, because of its extreme temperatures and pressures, WDM tends to be drastically transient and thus difficult to study in the laboratory. Now, researchers have set up ultrafast x-ray absorption spectroscopy at the ALS to measure the electronic structure of WDMs, demonstrating that fast-changing electron temperatures of matter under extreme conditions can be determined with picosecond resolution.

Advertising, economic development, and global warming  

Science Journals Connector (OSTI)

Abstract Advertising is tied to global warming through an endogenous growth model. The model allows for the possibility that the environment can become a source rather than a sink for greenhouse gases. Optimal control analysis of the model shows that a feasible steady state is possible for which the environment remains a sink, and identifies a sufficient condition for such to be the case. Comparative-static analysis shows that, for sufficiently small values of steady-state anthropogenic greenhouse gas concentration, global surface temperature and advertising in steady state are negative functions of parameters that measure the damaging effects of global warming.

Electrical conductivity of warm dense tungsten  

Science Journals Connector (OSTI)

Abstract The electrical conductivity of warm dense tungsten plasma has been investigated successfully by a linear mixture rule considering various interactions of electrons with electrons, atoms, and ions. The plasma composition is calculated by the nonideal Saha equation. The interesting regime for tungsten plasma spans from weakly coupled and nondegenerate regime to strongly coupled and partial degenerate state. The electrical conductivity calculated is in reasonable agreement with the exploding wire experiments and other theoretical models. The present result demonstrates that the theoretical model is valid for the electrical conductivity of tungsten plasma in the warm dense matter regime.

A reverse slapper detonator (70), and methodology related thereto, are provided. The detonator (70) is adapted to be driven by a pulse of electric power from an external source (80). A conductor (20) is disposed along the top (14), side (18), and bottom (16) surfaces of a sheetlike insulator (12). Part of the conductor (20) comprises a bridge (28), and an aperture (30) is positioned within the conductor (20), with the bridge (28) and the aperture (30) located on opposite sides of the insulator (12). A barrel (40) and related explosive charge (50) are positioned adjacent to and in alignment with the aperture (30), and the bridge (28) is buttressed with a backing layer (60). When the electric power pulse vaporizes the bridge (28), a portion of the insulator (12) is propelled through the aperture (30) and barrel (40), and against the explosive charge (50), thereby detonating it.

Properly apply reverse osmosis  

SciTech Connect

Reverse osmosis (RO) is a water purification technique used to reduce the loading of dissolved solids in solution. The popularity of RO for treating boiler feedwater is growing because of the rising cost of ion-exchange-based demineralization as well as safety concerns associated with handling acid and caustic. A properly designed and operated RO-based boiler-feedwater-treatment system can reduce the load to, and costs associated with, ion exchange demineralization. This article discusses RO feedwater quality recommendations, pretreatment techniques, and system monitoring necessary to achieve optimum RO system performance in the most cost-effective manner. Regardless of the application--whether it is the treatment of boiler feedwater, industrial wastewater, or process water--the approach to pretreatment and the other design and operating guidance offered here remains the same.

DM particles: how warm they can be?  

SciTech Connect

One of important questions concerning particles which compose the Dark Matter (DM) is their average speed. We consider the model of relativistic weakly interacting massive particles and try to impose an upper bound on their actual and past warmness through the analysis of density perturbations and comparison with the LSS data. It is assumed that the DM can be described by the recently invented model of reduced relativistic gas (RRG). The equation of state of the RRG model is closely reproducing the one of the Maxwell distribution, while being much simpler. This advantage of the RRG model makes our analysis very efficient. As a result we arrive at the rigid and model-independent bound for the DM warmness without using the standard (much more sophisticated) approach based on the Einstein-Boltzmann system of equations.

Global Warming Mitigation Investments Optimized under Uncertainty Global Warming Mitigation Investments Optimized under Uncertainty Speaker(s): Hermann Held Date: July 9, 2010 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Thomas McKone The Copenhagen Accord (2009) recognizes that 'the increase in global temperature should be below 2 degrees Celsius' (compared to pre-industrial levels, '2° target'). In recent years, energy economics have derived welfare-optimal investment streams into low-emission energy mixes and associated costs. According to our analyses, auxiliary targets that are in line with the 2° target could be achieved at relatively low costs if energy investments were triggered rather swiftly. While such analyses assume 'perfect foresight' of a benevolent 'social planner', an accompanying suite of experiments explicitly

Computer modeling of the global warming effect  

SciTech Connect

The state of knowledge of global warming will be presented and two aspects examined: observational evidence and a review of the state of computer modeling of climate change due to anthropogenic increases in greenhouse gases. Observational evidence, indeed, shows global warming, but it is difficult to prove that the changes are unequivocally due to the greenhouse-gas effect. Although observational measurements of global warming are subject to ``correction,`` researchers are showing consistent patterns in their interpretation of the data. Since the 1960s, climate scientists have been making their computer models of the climate system more realistic. Models started as atmospheric models and, through the addition of oceans, surface hydrology, and sea-ice components, they then became climate-system models. Because of computer limitations and the limited understanding of the degree of interaction of the various components, present models require substantial simplification. Nevertheless, in their present state of development climate models can reproduce most of the observed large-scale features of the real system, such as wind, temperature, precipitation, ocean current, and sea-ice distribution. The use of supercomputers to advance the spatial resolution and realism of earth-system models will also be discussed.

Reversible micromachining locator  

DOE Patents (OSTI)

This invention provides a device which includes a locator, a kinematic mount positioned on a conventional tooling machine, a part carrier disposed on the locator and a retainer ring. The locator has disposed therein a plurality of steel balls, placed in an equidistant position circumferentially around the locator. The kinematic mount includes a plurality of magnets which are in registry with the steel balls on the locator. In operation, a blank part to be machined is placed between a surface of a locator and the retainer ring (fitting within the part carrier). When the locator (with a blank part to be machined) is coupled to the kinematic mount, the part is thus exposed for the desired machining process. Because the locator is removably attachable to the kinematic mount, it can easily be removed from the mount, reversed, and reinserted onto the mount for additional machining. Further, the locator can likewise be removed from the mount and placed onto another tooling machine having a properly aligned kinematic mount. Because of the unique design and use of magnetic forces of the present invention, positioning errors of less than 0.25 micrometer for each machining process can be achieved. 7 figs.

Modelling Reverse Osmosis  

Science Journals Connector (OSTI)

After a brief presentation of the principal kinetic and thermodynamic aspects of the theory of reverse osmosis, the present review examines various physicochemical mechanisms of the selectivity of membranes with respect to electrolyte solutions: the electrochemical mechanism, related to the charge of the pore surface; the dielectric exclusion of ions, due to image forces; and the structural mechanism, due to the change in the properties of water in fine hydrophilic pores. Methods for calculating the changes in the standard chemical potentials of ions on entering the membrane phase, and the effects of the Donnan exclusion of ions with allowance for the different charge of the membrane have been described. It has been concluded that it is appropriate to use charged membranes to separate electrolyte solutions at low concentrations. The problem of the transport of solutions through the fine pores of membranes has been formulated, taking account of the equilibrium distribution coefficients of the ions, their mobility, the charge of the membrane, and the phenomenon of concentration polarisation. Routes to the further development of the theory as applied to membranes of different types, different compositions, and solution concentrations have been discussed. The bibliography contains 84 references.

Reverse osmosis reverses conventional wisdom with Superfund cleanup success  

SciTech Connect

Although widely recognized as the most efficient means of water purification, reverse osmosis has not been considered effective for remediating hazardous wastewater. Scaling and fouling, which can cause overruns and downtime, and require membrane replacement, have inhibited success in high-volume wastewater applications. Despite this background, a reverse osmosis technology developed in Europe recently was used successfully to treat large volumes of contaminated water at a major Superfund site in Texas. The technology's success there may increase the chances for reverse osmosis to find wider use in future cleanups and other waste treatment applications.

Coastal regions have a high social, economical and environmental importance. Due to this importance the sea level fluctuations can have many bad consequences. In this research the correlation between the increasing trend of temperature in coastal stations due to Global Warming and the Caspian Sea level has been established. The Caspian Sea level data has been received from the Jason-1 satellite. It was resulted that the monthly correlation between the temperature and sea level is high and also positive and almost the same for all the stations. But the yearly correlation was negative. It means that the sea level has decreased by the increase in temperature.

Warm inflation in presence of magnetic fields  

SciTech Connect

We present preliminary results on the possible effects that primordial magnetic fields can have for a warm inflation scenario, based on global supersymmetry, with a new-inflation-type potential. This work is motivated by two considerations: first, magnetic fields seem to be present in the universe on all scales which rises de possibility that they could also permeate the early universe; second, the recent emergence of inflationary models where the inflaton is not assumed to be isolated but instead it is taken as an interacting field, even during the inflationary expansion. The effects of magnetic fields are included resorting to Schwinger's proper time method.

100 LPW 800 Lm Warm White LED  

SciTech Connect

An illumination grade warm white (WW) LED, having correlated color temperature (CCT) between 2800 K and 3500K and capable of producing 800 lm output at 100 lm/W, has been developed in this program. The high power WW LED is an ideal source for use as replacement for incandescent, and Halogen reflector and general purpose lamps of similar lumen value. Over the two year period, we have made following accomplishments: developed a high power warm white LED product and made over 50% improvements in light output and efficacy. The new high power WW LED product is a die on ceramic surface mountable LED package. It has four 1x1 mm{sup 2} InGaN pump dice flip chip attached to a ceramic submount in 2x2 array, covered by warm white phosphor ceramic platelets called Lumiramicâ?¢ and an overmolded silicone lens encapsulating the LED array. The performance goal was achieved through breakthroughs in following key areas: (1) High efficiency pump LED development through pump LED active region design and epi growth quality improvement (funded by internal programs). (2) Increase in injection efficiency (IE) represented by reduction in forward voltage (V{sub f}) through the improvement of the silver-based p-contact and a reduction in spreading resistance. The injection efficiency was increased from 80% at the start of the program to 96% at the end of the program at 700 mA/mm{sup 2}. (3) Improvement in thermal design as represented by reduction in thermal resistance from junction to case, through improvement of the die to submount connection in the thin film flip chip (TFFC) LED and choosing the submount material of high thermal conductivity. A thermal resistance of 1.72 K/W was demonstrated for the high power LED package. (4) Improvement in extraction efficiency from the LED package through improvement of InGaN die level and package level optical extraction efficiency improvement. (5) Improvement in phosphor system efficiency by improving the lumen equivalent (LE) and phosphor package efficiency (PPE) through improvement in phosphor-package interactions. Another achievement in the development of the phosphor integration technology is the demonstration of tight color control. The high power WW LED product developed has been proven to have good reliability. The manufacturing of the product will be done in Philips Lumiledsâ?? LUXEON Rebel production line which has produced billions of high power LEDs. The first high power WW LED product will be released to the market in 2011.

Electrowetting on liquid-infused film (EWOLF): Complete reversibility and controlled droplet oscillation suppression for fast optical imaging  

E-Print Network (OSTI)

Electrowetting on dielectric (EWOD) has emerged as a powerful tool to electrically manipulate tiny individual droplets in a controlled manner. Despite tremendous progress over the past two decades, current EWOD operating in ambient conditions has limited functionalities posing challenges for its applications, including electronic display, energy generation, and microfluidic systems. Here, we demonstrate a new paradigm of electrowetting on liquid-infused film (EWOLF) that allows for complete reversibility and tunable transient response simultaneously. We determine that these functionalities in EWOLF are attributed to its novel configuration, which allows for the formation of viscous liquid-liquid interfaces as well as additional wetting ridges, thereby suppressing the contact line pinning and severe droplet oscillation encountered in the conventional EWOD. Finally, by harnessing these functionalities demonstrated in EWOLF, we also explore its application as liquid lens for fast optical focusing.

Warming systems prolong steam-turbine life, accelerate startup  

SciTech Connect

Cycling capability is one of the top challenges in the design, operation, and maintenance of today's powerplants. This article describes how permanent warming systems can be a powerful ally in meeting this challenge, particularly for aging steam turbines. The warming system is typically used to hold steam-turbine shell temperatures during short shutdowns (up to about three days), or to pre-warm shells after longer shut-downs. Permanent warming systems elevate metal temperature above 500 F, distinguishing them from heat tracing systems that operate at much lower temperatures for freeze protection or viscosity control. Permanent warming systems can reduced steam-turbine damage during both startup heating and off-line cooling, and can reduce plant startup time.

4 - Modeling the Relationship Between Global Warming, Violence, and Crime  

Science Journals Connector (OSTI)

Abstract One of the challenges of global warming research to the social sciences is that physical science research modalities are different. Consequently, efforts to tie it to the social sciences, particularly those related to violence and crime, are difficult to develop. This chapter looks at two models to assess the linkages between global warming and crime. The first, the Homer-Dixon model, uses a resource scarcity model to look at these linkages. According to the Homer-Dixon model, many aspects of global warming produce scarcities such as food shortages, ranch and farmland loss, and clean-water shortages. By tracing the indirect effects of scarcities through intervening variables of migration and state hardening, the model allows us to see various kinds of crime and violence that might happen under global warming conditions. The second model is the Agnew model, developed to assess theoretical linkages between crime and global warming, primarily focusing on social disorganization and strain perspectives. The second model fills a critical shortcoming in the first model; it provides a nuanced notion of crime and crime theory. Hence, it provides a needed “back end” of crime outcomes to tie into the Homer-Dixon model. Also, we discuss the way in which many dimensions of global warming can be modeled relatively straightforwardly into a routine activities perspective, where the social and economic disruptions caused by global warming give rise to new patterns of human activity and, consequently, new patterns of criminal and predatory activities.

Integrated Warm Gas Multicontaminant Cleanup Technologies for Coal-Derived Syngas Integrated Warm Gas Multicontaminant Cleanup Technologies for Coal-Derived Syngas Project Number: DE-FC26-05NT42459 Integrated Warm Gas Multicontaminant Cleanup Technologies for Coal-Derived Syngas Project ID: DE-FC26-05NT42459 Objective: The objective is to develop a warm multi-contaminant syngas cleaning system for operation between 300 and 700° F. This project will continue development of the RTI warm syngas cleanup technology suite. Based on the field testing results with real syngas from Eastman Chemical Company's gasifier under DOE Contract DE-AC26-99FT40675, additional technical issues need to be addressed to move the technologies used in warm syngas cleaning further towards commercial deployment especially for chemical/fuels production. These issues range from evaluation of startup and standby options for the more developed desulfurization processes to integration and actual pilot plant testing with real coal-derived syngas for the technologies that were tested at bench scale during Phase I. Development shall continue of the warm gas syngas cleaning technology platform through a combination of lab-scale R&D and larger integrated pilot plant testing with real coal-derived syngas as well as process/systems analysis and simulation for optimization of integration and intensification.

11 - Security Issues and Global Warming  

Science Journals Connector (OSTI)

Abstract This chapter begins with a discussion of the increasing empowerment of nonstate actors to challenge nation-states for commerce and security. One of the central trends is the operational coordination of organized crime and terrorist entities. They tend to share the same pipelines and at times some of the same personnel since both have a need for similar specialized skills. We witness the emergence of the third generation of guerillas, described as leaderless or horizontal in structure, global, and highly adaptable to urban areas. Crevald’s position on guerilla wars is discussed—he asserted that states can never effectively combat guerilla wars. We then discuss the many ways in which transnational criminal organizations and terrorists are working together in the current era. From there, we assess the roles of criminalized states and “black holes,” geographical areas not controlled by state-based security entities. We discuss how global warming works to enhance the strengths of nonstate actors, while at the same time undermining or limiting state security. This chapter closes with a discussion of the security changes likely to be associated with an ice-free Arctic Ocean. We look at changes already occurring, and assess the roles played by the United States, Canada, Russia, and China. All are in exploration stages for previously inaccessible resources, and most are increasing their military presence across the region.

Reverse engineering of integrated circuits  

DOE Patents (OSTI)

Software and a method therein to analyze circuits. The software comprises several tools, each of which perform particular functions in the Reverse Engineering process. The analyst, through a standard interface, directs each tool to the portion of the task to which it is most well suited, rendering previously intractable problems solvable. The tools are generally used iteratively to produce a successively more abstract picture of a circuit, about which incomplete a priori knowledge exists.

Reversible Seeding in Storage Rings  

SciTech Connect

We propose to generate steady-state microbunching in a storage ring with a reversible seeding scheme. High gain harmonic generation (HGHG) and echo-enabled harmonic generation (EEHG) are two promising methods for microbunching linac electron beams. Because both schemes increase the energy spread of the seeded beam, they cannot drive a coherent radiator turn-by-turn in a storage ring. However, reversing the seeding process following the radiator minimizes the impact on the electron beam and may allow coherent radiation at or near the storage ring repetition rate. In this paper we describe the general idea and outline a proof-of-principle experiment. Electron storage rings can drive high average power light sources, and free-electron lasers (FELs) are now producing coherent light sources of unprecedented peak brightness While there is active research towards high repetition rate FELs (for example, using energy recovery linacs), at present there are still no convenient accelerator-based sources of high repetition rate, coherent radiation. As an alternative avenue, we recently proposed to establish steady-state microbunching (SSMB) in a storage ring. By maintaining steady-state coherent microbunching at one point in the storage ring, the beam generates coherent radiation at or close to the repetition rate of the storage ring. In this paper, we propose a method of generating a microbunched beam in a storage ring by using reversible versions of linac seeding schemes.

Physical aspects of the greenhouse effect and global warming  

Science Journals Connector (OSTI)

According to the simplest model of the earth’s radiative balance global warming will occur with certainty as humankind increases its production and consumption of nonsolar energy. This prediction is revisited using a broader model that allows the greenhouse effect to be considered. The new model predicts a global warming of ?T E =(114? K )? where ? is the rate of surface energy release in units of the average incident solar radiation 342? W?m ?2 and ?T E is the average temperature rise at the earth’s surface. Present values of these quantities excluding geothermal sources are ?=0.69×10 ?4 and ?T E =7.9? mK . The model assigns a small number of optical parameters to the atmosphere and surface and qualifies the simple warming prediction: It is rigorous only if parameters other than ? are unchanged. The model is not complex and should serve as an aid to an elementary understanding of global warming.

R&D for technology to solve global warming  

Science Journals Connector (OSTI)

Global warming is a problem in which the combustion of coal, oil, and other fossil fuels causes the atmospheric concentrations of greenhouse gases, such as carbon dioxide (CO2), to increase. This results in mounting global air temperatures that lead to climatic change. Specifically, global warming will cause a rise in sea levels, changes in the rain-fall patterns, and other problems. In order to secure the route to solutions for global warming that requires new responses in ways that are compatible with economic growth, it is essential to achieve breakthroughs with innovative technologies. In addition to energ-related R&D, also important are R&D for CO2 absorption and fixation for fundamental solution to global warming. Japan has started the development of innovative environmental technologies, such as technologies for CO2 fixation and utilization.

Warm Cores around Regions of Low-Mass Star Formation  

E-Print Network (OSTI)

Warm cores (or hot corinos) around low-mass protostellar objects show a rich chemistry with strong spatial variations. This chemistry is generally attributed to the sublimation of icy mantles on dust grains initiated by the warming effect of the stellar radiation. We have used a model of the chemistry in warm cores in which the sublimation process is based on extensive laboratory data; these data indicate that sublimation from mixed ices occurs in several well-defined temperature bands. We have determined the position of these bands for the slow warming by a solar-mass star. The resulting chemistry is dominated by the sublimation process and by subsequent gas-phase reactions; strong spatial and temporal variations in certain molecular species are found to occur, and our results are, in general, consistent with observational results for the well-studied source IRAS 16293-2422. The model used is similar to one that describes the chemistry of hot cores. We infer that the chemistry of both hot cores and warm core...

An overview of time?reversal acoustics  

Science Journals Connector (OSTI)

Time?reversal invariance is a very powerful concept in physics. In the field of acoustics where time reversal invariance occurs time?reversal experiments may be achieved simply with arrays of transmit?receive transducers allowing an incident wave field to be sampled recorded time?reversed and re?emitted. Time reversal mirrors (TRMs) may be used to study random media and chaotic reverberating structures. Common to these complex media is a remarkable robustness exemplified by observations that the more complex the medium between the probe source and the TRM the sharper the focus. TRMs open the way to new signal processings that interest imaging detection telecommunications and therapy. Time reversal mirrors have plenty of applications including ultrasonic therapy and medical imaging non destructive testing telecommunications underwater acoustics seismology sound control home automation. An overview of these fields will be presented.

Legendary West Virginia Senior Citizen Stays Warm With New Furnace Legendary West Virginia Senior Citizen Stays Warm With New Furnace Legendary West Virginia Senior Citizen Stays Warm With New Furnace April 1, 2010 - 7:16pm Addthis Joshua DeLung For the last 56 years, Beulah Sisk has lived in the same house in Princeton, W.Va. Beulah, who worked for 25 years at Lloyd's Pastry Shop, is well known in Princeton. People still see her on the streets today and recognize her as an icon in the community. After a wind storm damaged Beulah's home last year, it came as no surprise when a senior center employee, concerned for Beulah's safety, told her about the weatherization assistance program. "A tree fell on my house and damaged a lot of things, including my furnace," Beulah says. "I tried to have it repaired, but it still

NETL: Gasification Systems - Warm Gas Multi-Contaminant Removal System  

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

Warm Gas Multi-Contaminant Removal System Warm Gas Multi-Contaminant Removal System Project Number: DE-SC00008243 TDA Research, Inc. is developing a high-capacity, low-cost sorbent that removes anhydrous ammonia (NH3), mercury (Hg), and trace contaminants from coal- and coal/biomass-derived syngas. The clean-up system will be used after the bulk warm gas sulfur removal step, and remove NH3 and Hg in a regenerable manner while irreversibly capturing all other trace metals (e.g., Arsenic, Selenium) reducing their concentrations to sub parts per million (ppm) levels. Current project plans include identifying optimum chemical composition and structure that provide the best sorbent performance for removing trace contaminants, determining the effect of operating parameters, conducting multiple-cycle experiments to test the life of the sorbent for NH3 and Hg removal, and conducting a preliminary design of the sorbent reactor.

Global warming description using Daisyworld model with greenhouse gases  

Science Journals Connector (OSTI)

Abstract Daisyworld is an archetypal model of the earth that is able to describe the global regulation that can emerge from the interaction between life and environment. This article proposes a model based on the original Daisyworld considering greenhouse gases emission and absorption, allowing the description of the global warming phenomenon. Global and local analyses are discussed evaluating the influence of greenhouse gases in the planet dynamics. Numerical simulations are carried out showing the general qualitative behavior of the Daisyworld for different scenarios that includes solar luminosity variations and greenhouse gases effect. Nonlinear dynamics perspective is of concern discussing a way that helps the comprehension of the global warming phenomenon.

Reversible chemisorption on highly dispersed Ru catalysts  

SciTech Connect

Hydrogen and carbon monoxide adsorptions have been studied by static gas volumetric measurement on a range of highly dispersed Y-zeolite-supported ruthenium catalysts prepared by ion exchange. At ambient temperature, the absorption isotherms indicated two distinct types of adsorption - reversible (composed of both physisorption and weak chemisorption) and irreversible (strongly chemisorbed). The catalysts were highly dispersed and had average particle diameters ranging from 0.9 to 1.6 nm. Reversible hydrogen chemisorption was found to be a function of average particle diameter and dispersion. On the other hand, reversible carbon monoxide chemisorption seemed to be mainly due to interaction with the support.

An analytic model for the performance of reverse osmosis desalination systems is derived. Predictions are shown to agree well with extensive measurements conducted on a commercial multistage reverse osmosis desalination unit over a broad range of operating conditions. The model allows a transparent understanding of the dependence of system performance on key design and operating variables. Identifying the characteristic flow rate and length scale of reverse osmosis systems allows a universal description of the variation of the permeate flow rate and recovery factor with the salinity flow rate and pressure of the feedwater.

Direct Imaging of Asymmetric Magnetization Reversal  

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

Direct Imaging of Asymmetric Magnetization Reversal Print Direct Imaging of Asymmetric Magnetization Reversal Print The phenomenon of exchange bias has transformed how data is read on magnetic hard disks and created an explosion in their information storage density. However, it remains poorly understood, and even the fundamental mechanism of magnetic reversal for exchange-biased systems in changing magnetic fields is unclear. By using x-ray photoemission electron microscopy at the ALS to directly image the magnetic structure of an exchange-biased film, a team from the University of Washington and the Stanford Synchrotron Radiation Laboratory has identified separate magnetic-reversal mechanisms in the two branches of a hysteresis loop. This advance in fundamental understanding will provide new insights for developing the next generation of information storage and sensing devices where exchange bias is expected to play a critical role.

Reversing the Circulation of Magnetic Vortices  

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

Reversing the Circulation of Reversing the Circulation of Magnetic Vortices Reversing the Circulation of Magnetic Vortices Print Wednesday, 31 July 2013 00:00 In magnetic media, information is stored in binary form-one or zero, depending on which way the electronic spins are aligned in a given section of the medium. Recently, however, magnetic vortices have drawn scientists toward a new possibility: multibit storage in which each logic unit has four states instead of two and can store twice the information. Each tiny magnetic whirl has a polarity that can point up or down and a circulation that can be oriented clockwise or counterclockwise. Previous studies have shown that the polarity can be flipped on command. Now, using time-resolved magnetic soft x-ray microscopy at the ALS, researchers have shown for the first time how to use pulsed magnetic fields to reverse the circulation.

COSMIC RAY HEATING OF THE WARM IONIZED MEDIUM  

SciTech Connect

Observations of line ratios in the Milky Way's warm ionized medium suggest that photoionization is not the only heating mechanism present. For the additional heating to explain the discrepancy, it would have to have a weaker dependence on the gas density than the cooling rate, {Lambda}n{sub e}{sup 2}. Reynolds et al. suggested turbulent dissipation or magnetic field reconnection as possible heating sources. We investigate here the viability of MHD-wave mediated cosmic ray heating as a supplemental heating source. This heating rate depends on the gas density only through its linear dependence on the Alfven speed, which goes as n{sub e}{sup -1/2}. We show that, scaled to appropriate values of cosmic ray energy density, cosmic ray heating can be significant. Furthermore, this heating is stable to perturbations. These results should also apply to warm ionized gas in other galaxies.

A prairie perspective on global warming and climate change  

Science Journals Connector (OSTI)

The Great Plains blankets eight states. It is dotted with oil patches, public utilities, farms, ranches, feed lots, meat-packing plants, medium size cities, military bases and tiny towns feeding on agricultural activity. The question is: what can leaders do for a desperate and aging population in a global warming environment to bring full employment to the region. This paper explores opportunities to capitalise upon environmentally friendly farming practices and agricultural waste to produce jobs, money, commercial opportunities, marketable sod, fertilisers, methane, electricity and securities (from the Chicago Climate Exchange) as answers for this question. The paper recounts the use of man made wetlands to sequester CO2; by-products from coal fired power plants; landfill methane; methane digesters and soil carbon projects to arrest heat and contribute to the campaign against global warming.

Surface electromagnetic wave equations in a warm magnetized quantum plasma  

SciTech Connect

Based on the single-fluid plasma model, a theoretical investigation of surface electromagnetic waves in a warm quantum magnetized inhomogeneous plasma is presented. The surface electromagnetic waves are assumed to propagate on the plane between a vacuum and a warm quantum magnetized plasma. The quantum magnetohydrodynamic model includes quantum diffraction effect (Bohm potential), and quantum statistical pressure is used to derive the new dispersion relation of surface electromagnetic waves. And the general dispersion relation is analyzed in some special cases of interest. It is shown that surface plasma oscillations can be propagated due to quantum effects, and the propagation velocity is enhanced. Furthermore, the external magnetic field has a significant effect on surface wave's dispersion equation. Our work should be of a useful tool for investigating the physical characteristic of surface waves and physical properties of the bounded quantum plasmas.

Constraining warm dark matter with cosmic shear power spectra  

SciTech Connect

We investigate potential constraints from cosmic shear on the dark matter particle mass, assuming all dark matter is made up of light thermal relic particles. Given the theoretical uncertainties involved in making cosmological predictions in such warm dark matter scenarios we use analytical fits to linear warm dark matter power spectra and compare (i) the halo model using a mass function evaluated from these linear power spectra and (ii) an analytical fit to the non-linear evolution of the linear power spectra. We optimistically ignore the competing effect of baryons for this work. We find approach (ii) to be conservative compared to approach (i). We evaluate cosmological constraints using these methods, marginalising over four other cosmological parameters. Using the more conservative method we find that a Euclid-like weak lensing survey together with constraints from the Planck cosmic microwave background mission primary anisotropies could achieve a lower limit on the particle mass of 2.5 keV.

Global warming potential for CF[sub 4  

SciTech Connect

With sufficient emissions, fluorinated gases such as CF[sub 4] could contribute significantly to the concerns about global warming because they are greenhouse gases, are chemically very inert, and have long accumulation lifetimes in the atmosphere. At this time, the only significant known source of CF[sub 4] is primary aluminum smelting (Abrahamson, 1992). While current emissions are small, additional sources could make CF[sub 4] an important contribution to climate forcing in the future.

impacts of warming temperatures on California's electricity impacts of warming temperatures on California's electricity system Title Estimating impacts of warming temperatures on California's electricity system Publication Type Journal Article Year of Publication 2013 Authors Sathaye, Jayant A., Larry L. Dale, Peter H. Larsen, Gary A. Fitts, Kevin Koy, Sarah M. Lewis, and André Frossard Pereira de Lucena Journal Global Environmental Change Volume 23 Start Page 499 Issue 2 Pagination 499-511 Date Published 04/2013 Keywords EES-EG, electricity markets and policy group Abstract Despite a clear need, little research has been carried out at the regional-level to quantify potential climate-related impacts to electricity production and delivery systems. This paper introduces a bottom-up study of climate change impacts on California's energy infrastructure, including high temperature effects on power plant capacity, transmission lines, substation capacity, and peak electricity demand. End-of-century impacts were projected using the A2 and B1 Intergovernmental Panel on Climate Change emission scenarios. The study quantifies the effect of high ambient temperatures on electricity generation, the capacity of substations and transmission lines, and the demand for peak power for a set of climate scenarios. Based on these scenarios, atmospheric warming and associated peak demand increases would necessitate up to 38% of additional peak generation capacity and up to 31% additional transmission capacity, assuming current infrastructure. These findings, although based on a limited number of scenarios, suggest that additional funding could be put to good use by supporting R&D into next generation cooling equipment technologies, diversifying the power generation mix without compromising the system's operational flexibility, and designing effective demand side management programs.

Cores and cusps in warm dark matter halos  

SciTech Connect

The apparent presence of large core radii in Low Surface Brightness galaxies has been claimed as evidence in favor of warm dark matter. Here we show that WDM halos do not have cores that are large fractions of the halo size: typically, r{sub core}/r{sub 200}?<10{sup ?3}. This suggests an astrophysical origin for the large cores observed in these galaxies, as has been argued by other authors.

Forestry and global warming: the physical and policy linkages  

Science Journals Connector (OSTI)

The potential for biotically mitigating global warming is receiving a great deal of policy and technical attention around the world. Elements of the political community are drawn to the notion that land?use patterns can be modified more easily than energy consumption patterns and some modelers suggest that the potential for storing carbon in terrestrial ecosystems is very large. Most work to date however uses only physical criteria in estimating how much land might be available for reforestation. Accounting for social and economic constraints is much more difficult resulting in daunting uncertainty about what could actually be accomplished. Furthermore our relative ignorance of the functioning of the global carbon cycle makes attempting to manipulate it for human purposes questionable at best. Nevertheless there are many reasons besides global warming to pursue a radical restructuring of land?use patterns around the world. Such a restructuring should be undertaken in conjunction with many other measures to slow global warming most immediately in the energy sector.

Variance in trace constituents following the final stratospheric warming  

SciTech Connect

Temporal variances in the concentration of trace species are examined within the northern hemisphere stratosphere following the final warming. Variances are computed utilizing an annual cycle run of a tracer transport model and stratospheric balloon observations. The model uses winds generated with a general circulation model to transport N{sub 2}O. Regions of significant N{sub 2}O variance are produced immediately following the modeled final warming as zonally inhomogeneous N{sub 2}O anomalies are created during the warming, then advected passively about the pole by easterly winds. Diffusion rapidly dissipates these anomalies and decreases the associated stratospheric tracer variance to very low levels by June. On monthly timescales the 10 day normal mode explains up to 50% of the modeled variance of N{sub 2}O during summer. On these timescales potential temperature exhibits less variability than N{sub 2}O, as horizontal parcel displacements are relatively ineffective at inducing potential temperature variability. An examination of balloon observations of N{sub 2}O and other long lived trace species, between 40{degree} and 50{degree}N, indicates that the primary component of the tracer variance during June is on an interannual time scale. The authors attribute this interannual variability to stratospheric variability during the winter and early spring months imprinted onto the distributions of long lived tracers. Potential temperatures does not exhibit much interannual variability because it does not retain a memory of the previous winters circulation.

Development of an integrated reverse engineering system  

Science Journals Connector (OSTI)

This paper describes the development of a customised reverse engineering system in which a 3D digitiser (MicroScribe-3DX) has been integrated with a computer-aided design (CAD) system (Pro/ENGINEER). The application programme written in C language enables a real-time input from the digitiser to Pro/ENGINEER. Two Application Programming Interfaces (APIs) were used: the MicroScribe-3D Software Development Kit (SDK) and Pro/TOOLKIT. The former allows the user to develop an integrated system through intuitive and high-level function calls to the digitiser. The latter enables a user to customise a Pro/ENGINEER environment. This system offers an intuitive and user-friendly means for reverse engineering. It also helps to shorten the whole reverse engineering process. This is because the digitised data can be displayed and edited in real time, so that early identification and exclusion of the undesired and incorrect data are made possible.

Optimal design of reverse osmosis module networks  

SciTech Connect

The structure of individual reverse osmosis modules, the configuration of the module network, and the operating conditions were optimized for seawater and brackish water desalination. The system model included simple mathematical equations to predict the performance of the reverse osmosis modules. The optimization problem was formulated as a constrained multivariable nonlinear optimization. The objective function was the annual profit for the system, consisting of the profit obtained from the permeate, capital cost for the process units, and operating costs associated with energy consumption and maintenance. Optimization of several dual-stage reverse osmosis systems were investigated and compared. It was found that optimal network designs are the ones that produce the most permeate. It may be possible to achieve economic improvements by refining current membrane module designs and their operating pressures.

FINAL REPORT WIND POWER WARM SPRINGS RESERVATION TRIBAL LANDS DOE GRANT NUMBER DE-FG36-07GO17077 SUBMITTED BY WARM SPRINGS POWER & WATER ENTERPRISES A CORPORATE ENTITY OF THE CONFEDERATED TRIBES OF WARM SPRINGS WARM SPRINGS, OREGON  

SciTech Connect

Wind Generation Feasibility Warm Springs Power and Water Enterprises (WSPWE) is a corporate entity owned by the Confederated Tribes of the Warm Springs Reservation, located in central Oregon. The organization is responsible for managing electrical power generation facilities on tribal lands and, as part of its charter, has the responsibility to evaluate and develop renewable energy resources for the Confederated Tribes of Warm Springs. WSPWE recently completed a multi-year-year wind resource assessment of tribal lands, beginning with the installation of wind monitoring towers on the Mutton Mountains site in 2003, and collection of on-site wind data is ongoing. The study identified the Mutton Mountain site on the northeastern edge of the reservation as a site with sufficient wind resources to support a commercial power project estimated to generate over 226,000 MWh per year. Initial estimates indicate that the first phase of the project would be approximately 79.5 MW of installed capacity. This Phase 2 study expands and builds on the previously conducted Phase 1 Wind Resource Assessment, dated June 30, 2007. In order to fully assess the economic benefits that may accrue to the Tribes through wind energy development at Mutton Mountain, a planning-level opinion of probable cost was performed to define the costs associated with key design and construction aspects of the proposed project. This report defines the Mutton Mountain project costs and economics in sufficient detail to allow the Tribes to either build the project themselves or contract with a developer under the most favorable terms possible for the Tribes.

Measure Guideline: Supplemental Dehumidification in Warm-Humid Climates  

SciTech Connect

This document covers a description of the need and applied solutions for supplemental dehumidification in warm-humid climates, especially for energy efficient homes where the sensible cooling load has been dramatically reduced. In older homes in warm-humid climates, cooling loads are typically high and cooling equipment runs a lot to cool the air. The cooling process also removes indoor moisture, reducing indoor relative humidity. However, at current residential code levels, and especially for above-code programs, sensible cooling loads have been so dramatically reduced that the cooling system does not run a lot to cool the air, resulting in much less moisture being removed. In these new homes, cooling equipment is off for much longer periods of time especially during spring/fall seasons, summer shoulder months, rainy periods, some summer nights, and some winter days. In warm-humid climates, those long off periods allow indoor humidity to become elevated due to internally generated moisture and ventilation air change. Elevated indoor relative humidity impacts comfort, indoor air quality, and building material durability. Industry is responding with supplemental dehumidification options, but that effort is really in its infancy regarding year-round humidity control in low-energy homes. Available supplemental humidity control options are discussed. Some options are less expensive but may not control indoor humidity as well as more expensive and comprehensive options. The best performing option is one that avoids overcooling and avoids adding unnecessary heat to the space by using waste heat from the cooling system to reheat the cooled and dehumidified air to room-neutral temperature.

Tokamak Equilibria with Reversed Current Density  

Science Journals Connector (OSTI)

Observations of nearly zero toroidal current in the central region of tokamaks (the “current hole”) raises the question of the existence of toroidal equilibria with very low or reversed current in the core. The solutions of the Grad-Shafranov equilibrium equation with hollow toroidal current density profile including negative current density in the plasma center are investigated. Solutions of the corresponding eigenvalue problem provide simple examples of such equilibrium configurations. More realistic equilibria with toroidal current density reversal are computed using a new equilibrium problem formulation and computational algorithm which do not assume nested magnetic surfaces.

Reversed Doppler Effect in Photonic Crystals  

Science Journals Connector (OSTI)

Nonrelativistic reversed Doppler shifts have never been observed in nature and have only been speculated to occur in pathological systems with simultaneously negative effective permittivity and permeability. This Letter presents a different, new physical phenomenon that leads to a nonrelativistic reversed Doppler shift in light. It arises when light is reflected from a moving shock wave propagating through a photonic crystal. In addition to reflection of a single frequency, multiple discrete reflected frequencies or a 10 GHz periodic modulation can also be observed when a single carrier frequency of wavelength 1????m is incident.

Performance of the SLD Warm Iron Calorimeter prototype  

SciTech Connect

A prototype hadron calorimeter, of similar design to the Warm Iron Calorimeter (WIC) planned for the SLD experiment, has been built and its performance has been studied in a test beam. The WIC is an iron sampling calorimeter whose active elements are plastic streamer tubes similar to those used for the Mont-Blanc proton decay experiment. The construction and operation of the tubes will be briefly described together with their use in an iron calorimeter - muon tracker. Efficiency, resolution and linearity have been measured in a hadron/muon beam up to 11 GeV. The measured values correspond to the SLD design goals.

Sheet metal stamping die design for warm forming  

DOE Patents (OSTI)

In metal stamping dies, by taking advantage of improved material flow by selectively warming the die, flat sections of the die can contribute to the flow of material throughout the workpiece. Local surface heating can be accomplished by placing a heating block in the die. Distribution of heating at the flat lower train central regions outside of the bend region allows a softer flow at a lower stress to enable material flow into the thinner, higher strain areas at the bend/s. The heating block is inserted into the die and is powered by a power supply.

Bypassing the malfunction junction in warm dense matter simulations  

E-Print Network (OSTI)

Simulation of warm dense matter requires computational methods that capture both quantum and classical behavior efficiently under high-temperature, high-density conditions. Currently, density functional theory molecular dynamics is used to model electrons and ions, but this method's computational cost skyrockets as temperatures and densities increase. We propose finite-temperature potential functional theory as an in-principle-exact alternative that suffers no such drawback. We derive an orbital-free free energy approximation through a coupling-constant formalism. Our density approximation and its associated free energy approximation demonstrate the method's accuracy and efficiency.

Flow reversal power limit for the HFBR  

SciTech Connect

The High Flux Beam Reactor (HFBR) is a pressurized heavy water moderated and cooled research reactor that began operation at 40 MW. The reactor was subsequently upgraded to 60 MW and operated at that level for several years. The reactor undergoes a buoyancy-driven reversal of flow in the reactor core following certain postulated accidents. Questions which were raised about the afterheat removal capability during the flow reversal transition led to a reactor shutdown and subsequent resumption of operation at a reduced power of 30 MW. An experimental and analytical program to address these questions is described in this report. The experiments were single channel flow reversal tests under a range of conditions. The analytical phase involved simulations of the tests to benchmark the physical models and development of a criterion for dryout. The criterion is then used in simulations of reactor accidents to determine a safe operating power level. It is concluded that the limit on the HFBR operating power with respect to the issue of flow reversal is in excess of 60 MW. Direct use of the experimental results and an understanding of the governing phenomenology supports this conclusion.

Global warming and oil spills could cool shoaling reefs  

SciTech Connect

High water temperature generated on reef flats have been implicated as one of the factors determining the ecological patterns and structural morphologies peculiar to shoaling reefs. In approximately ten years of water temperature and water level data from a shoaling reef flat at Punta Galeta (Caribbean Panama), water temperatures were dependent on water levels. Water temperatures ranged up to 38[degrees]C when daily minimum water depths over the reef crest were < 12 cm, but never exceeded 30[degrees]C when the minimum water levels were > 12 cm. If conservative predictions of sea level rise caused by global warming are correct, normal vertical accretion rates of the reef flat could keep pace with rising sea level until the middle of the next century; after that the occurrence of high water temperatures would be rapidly reduced. However, damage from an oil spill at Punta Galeta in 1986 was concentrated at the seaward margin of the reef flat, where biogenic processes control the overall vertical accretion of the reef platform. By slowing rates of vertical accretion, oil impact could potentially accelerate the effects of global warming on the ecology and morphology of the reef.

The British coal global warming R&D programme  

Science Journals Connector (OSTI)

The threat of possible global warming is sufficient to warrant ‘least regrets’ measures to reduce emissions of greenhouse gases and investigation of fallback options, such as carbon dioxide removal from coal-fired power plants. The Global Warming R&D Programme is investigating carbon dioxide removal options, sometimes called ‘Low CO2 Power Generation’. An assessment programme has estimated the thermal efficiency of a number of process schemes and concluded that gasification based systems, with the addition of a CO shift reactor and CO2 scrubbers or a membrane gas separator, provide promising approaches. A clean hydrogen fuel would be fired in a gas turbine and 90% of the CO2 removed and exported as a liquid stream for storage in exhausted oil or gas fields. Costs of such power plants are now being explored and a collaborative programme is commencing with membrane developers, with the aim of developing and testing membranes for this duty. The paper outlines the background and describes preparation for experimental work using CO2/H2 separating membranes.

Combating global warming via non-fossil fuel energy options  

Science Journals Connector (OSTI)

Non-fossil fuel energy options can help reduce or eliminate the emissions of greenhouse gases and are needed to combat climate change. Three distinct ways in which non-fossil fuel options can be used in society are examined here: the capture/production of non-fossil fuel energy sources, their conversion into appropriate energy carriers and increased efficiency throughout the life cycle. Non-fossil fuel energy sources are insufficient to avoid global warming in that they are not necessarily readily utilisable in their natural forms. Hydrogen energy systems are needed to facilitate the use of non-fossil fuels by converting them to two main classes of energy carriers: hydrogen (and hydrogen-derived fuels) and electricity. High efficiency is needed to allow the greatest benefits to be attained from energy options in terms of climate change and other factors. A case study is considered involving the production of hydrogen from non-fossil energy sources via thermochemical water decomposition. Thermochemical water decomposition provides a realistic future non-fossil fuel energy option, which can be driven by non-fossil energy sources (particularly nuclear or solar energy) and help combat global warming.

Surface reflectance and conversion efficiency dependence of technologies for mitigating global warming  

Science Journals Connector (OSTI)

A means of assessing the relative impact of different renewable energy technologies on global warming has been developed. All power plants emit thermal energy to the atmosphere. Fossil fuel power plants also emit CO2 which accumulates in the atmosphere and provides an indirect increase in global warming via the greenhouse effect. A fossil fuel power plant may operate for some time before the global warming due to its CO2 emission exceeds the warming due to its direct heat emission. When a renewable energy power plant is deployed instead of a fossil fuel power plant there may be a significant time delay before the direct global warming effect is less than the combined direct and indirect global warming effect from an equivalent output coal fired plant – the “business as usual” case. Simple expressions are derived to calculate global temperature change as a function of ground reflectance and conversion efficiency for various types of fossil fuelled and renewable energy power plants. These expressions are used to assess the global warming mitigation potential of some proposed Australian renewable energy projects. The application of the expressions is extended to evaluate the deployment in Australia of current and new geo-engineering and carbon sequestration solutions to mitigate global warming. Principal findings are that warming mitigation depends strongly on the solar to electric conversion efficiency of renewable technologies, geo-engineering projects may offer more economic mitigation than renewable energy projects and the mitigation potential of reforestation projects depends strongly on the location of the projects.

Reversible zwitterionic liquids, the reaction of alkanol guanidines, alkanol amidines, and diamines with CO2  

SciTech Connect

Carbon dioxide chemistry is increasingly relevant to real-world issues, thanks to global warming. Key chemistry issues currently being studied are the capture, storage, and utilization of CO2. While the relevance of capture and storage are obvious, the relevance of CO2 utilization is less clear. Although CO2 utilization is unlikely to consume significant quantities of CO2, it can be an significant strategy for the development of sustainable processes. As part of our research efforts towards CO2 utilization, some of us invented switchable solvents, meaning solvents that can switch reversibly from one version to another.1Our original version was a mixture of an amidine and an alcohol (equation 1, where B is a liquid amidine), but since then we and others have developed others such as guanidine/alcohol mixtures (equation 1, where B is a liquid guanidine),2 amidine/primary amine mixtures,3 and secondary amines (equation 2).4Switchable solvents of these types all convert from a low-polarity to a high-polarity ionic liquid form upon exposure to an atmosphere of CO2 and revert back to the low polarity form when the CO2 is removed by heat or flushing with inert gas. We also demonstrated that these switchable solvents can be used as reversible CO2-binding organic liquids (CO2BOLs) for CO2 capture, and are more energy-efficient in that role than aqueous solutions of ethanolamine.

A REVERSE SHOCK IN GRB 130427A  

SciTech Connect

We present extensive radio and millimeter observations of the unusually bright GRB 130427A at z = 0.340, spanning 0.67-12 days after the burst. We combine these data with detailed multi-band UV, optical, NIR, and Swift X-ray observations and find that the broadband afterglow emission is composed of distinct reverse shock and forward shock contributions. The reverse shock emission dominates in the radio/millimeter and at ?< 0.1 days in the UV/optical/NIR, while the forward shock emission dominates in the X-rays and at ?> 0.1 days in the UV/optical/NIR. We further find that the optical and X-ray data require a wind circumburst environment, pointing to a massive star progenitor. Using the combined forward and reverse shock emission, we find that the parameters of the burst include an isotropic kinetic energy of E{sub K,{sub iso}} ? 2 × 10{sup 53} erg, a mass loss rate of M-dot ?3×10{sup -8} M{sub ?} yr{sup –1} (for a wind velocity of 1000 km s{sup –1}), and a Lorentz factor at the deceleration time of ?(200 s) ? 130. Due to the low density and large isotropic energy, the absence of a jet break to ?15 days places only a weak constraint on the opening angle, ?{sub j} ?> 2.°5, and therefore a total energy of E{sub ?} + E{sub K} ?> 1.2 × 10{sup 51} erg, similar to other gamma-ray bursts (GRBs). The reverse shock emission is detectable in this burst due to the low circumburst density, which leads to a slow cooling shock. We speculate that this property is required for the detectability of reverse shocks in radio and millimeter bands. Following on GRB 130427A as a benchmark event, observations of future GRBs with the exquisite sensitivity of the Very Large Array and ALMA, coupled with detailed modeling of the reverse and forward shock contributions, will test this hypothesis.

Global warming and transport in Brazil - ethanol alternative  

Science Journals Connector (OSTI)

This paper deals with the risk of global warming as intensified by the carbon dioxide (CO2) emissions of the transport sector, particularly in gasoline-powered vehicles in Brazil. Car ownership and use are increasing rapidly partly because of very poor public transport quality, which, in turn, is causing higher emission levels of CO2. In this connection, the use of ethanol in Brazil for the transport sector may prove to be an important alternative, furthering the efforts to stabilise the actual level of gases in the atmosphere. The energy derived from biomass, and in this case, from a renewable, ''clean'' source, i.e., from sugar-cane, has the unquestionable advantage of permitting the almost complete reabsorption of CO2 emitted through the combustion of fuel alcohol. This closed cycle allows, in principle, the increase of the energy supply, essential for economic development, with fewer hazards to the environment.

Minimising the global warming potential of clay based geopolymers  

Science Journals Connector (OSTI)

Abstract Production of Portland cement (PC) binders contributes substantially to global CO2 production and various bodies including the Intergovernmental Panel on Climate Change (IPCC) have identified geopolymers as alternative binders with the potential to reduce these emissions. The hypothesis of this research is to investigate whether this is a realistic proposition in the light of limited waste materials such as fly ash and ground granulated blast furnace slag commonly used as geopolymer precursors. The effect of use of natural clay minerals as alternative precursors on global warming potential (GWP) is investigated. Methods of designing mixes with the lowest possible GWP are presented and these are compared to the GWP of PC and currently available metakaolin based geopolymer binders. It is concluded that it is possible to reduce the GWP by approximately 40%, but other impacts may increase.

Effective thermal conduction model for estimating global warming  

Science Journals Connector (OSTI)

This paper presents a simple way to approximate the dependence of the global mean air temperature at Earth’s surface on the atmospheric concentration of carbon dioxide. It treats the atmosphere as a blanket the effective thermal conductivity of which is a decreasing function of the amount of CO 2 present and does not involve the details of energy transport. The only data required are the CO 2 concentrations at the middle of the nineteenth and the end of the twentieth centuries and the shift in temperature that has occurred over that time. This elementary phenomenological energy-balance approach is well suited for undergraduate physics courses to illustrate thermal conduction and radiation by way of the very interesting and critically important example of greenhouse warming of Earth.

Dynamical instabilities of warm npe matter: {delta} meson effects  

SciTech Connect

The effects of {delta} mesons on the dynamical instabilities of cold and warm nuclear and stellar matter at subsaturation densities are studied in the framework of relativistic mean-field hadron models (NL3, NL{rho}, and NL{rho}{delta}) with the inclusion of the electromagnetic field. The distillation effect and the spinodals for all the models considered are discussed. The crust-core transition density and pressure are obtained as a function of temperature for {beta}-equilibrium matter with and without neutrino trapping. An estimation of the size of the clusters formed in the nonhomogeneous phase and the corresponding growth rates are made. It is shown that cluster sizes increase with temperature. The effects of the {delta} meson on the instability region are larger for low temperatures, very asymmetric matter, and densities close to the spinodal surface. It increases the distillation effect above {approx}0.4{rho}{sub 0} and has the opposite effect below that density.

Nuclear energy conversion systems for arresting global warming

Presently the global warming by CO2 emission from fossil fuel burning is becoming a serious issue. Especially, coal is the worse fossil fuel, because it emits the largest amount of CO2 per unit amount of heat generation. There seem to be two ways of reducing substantial CO2 emission rate of coal; they are, reforming coal to synthesis fuel with less CO2 emission and removing CO2 from flue gas of coal fired power station after burning coal. Present paper proposes two nuclear heat application systems which reform coal to methanol and four systems which produce chemical products or gasoline with CO2 collected from flue gas of coal fired power stations, as future options for reducing CO2 emission from coal. Advantage and disadvantage of the proposed systems are discussed.

Equation of state and optical properties of warm dense helium  

Science Journals Connector (OSTI)

We investigate the physical properties of warm dense helium under the conditions found in the atmospheres of cool white dwarfs using both a chemical model and ab initio simulations. A chemical model is developed for the low-ionization limit that includes the species He, He+, He2+, and electrons, and interactions between them. The ab initio calculations consist in quantum molecular dynamics (QMD) simulations. We use the generalized gradient approximation (GGA) to calculate the equation of state and the electrical and optical properties within the linear response theory. We further use an exact exchange hybrid (PBE0) density functional as well as the GW approximation to estimate the uncertainties on the electrical and optical properties resulting from the GGA approximation. While both the chemical model and the QMD simulations are in excellent agreement with the measured equation of state, a qualitative discrepancy exists with the measured conductivity.

Constructing warm inflationary model in brane-antibrane system  

E-Print Network (OSTI)

Recently, various observational data predict a possibility that inflation may naturally occur in a warm region. In this scenario, radiation is produced during the inflation epoch and reheating is avoided. The main question arises that what is the origin of warm inflation in 4D universe? We answer to this question in brane-antibrane system. We propose a model that allows all cosmological parameters like the scale factor a, the Hubble parameter H and phantom energy density depend on the equation of state parameter in transverse dimension between two branes. Thus, an enhancement in these parameters can be a signature of some evolutions in extra dimension. In our model, the expansion of 4D universe is controlled by the separation distance between branes and evolves from non-phantom phase to phantom one. Consequently, phantom-dominated era of the universe accelerates and ends up in big-rip singularity. Also, we show that as the tachyon potential increases, the effect of interaction between branes on the 4D universe expansion becomes systematically more effective, because at higher energies there exists more channels for flowing energy from extra dimension to other four dimensions. Finally, we test our model against WMAP and Planck data and obtain the ripping time. According to experimental data, $N\\simeq 50$ case leads to $n_{s}\\simeq 0.96$, where \\emph{N} and $n_{s}$ are the number e-folds and the spectral index respectively. This standard case may be found in $0.01 occurs is $t_{rip}=33(Gyr)$.

Heart rate change and attitudes to global warming: A conceptual replication of the visceral fit mechanism  

Science Journals Connector (OSTI)

Abstract Visceral fit effects occur when a physical state (e.g., warmth) increases the plausibility of future related states (e.g., global warming). We attempted to conceptually replicate such effects by investigating whether belief in global warming is influenced by a change in heart rate, which is linked to body warmth. In four studies, participants' heart rates were varied via mental manipulation or physical exercise. In three of the studies, increased heart rate was associated with greater self-reported belief that global warming was occurring. Across all studies, the association between heart rate and self-reported belief in global warming was small in statistical effect size and very small in absolute terms. We suggest that the effects of incidental cues are interesting because such factors should not influence global warming beliefs at all, but the small absolute size of the effects means that situational cues are unlikely to alter a person's stance on climate change.

Time Reversal in Solids (Linear and Nonlinear Elasticity): Multimedia Resources in Time Reversal  

DOE Data Explorer (OSTI)

Dynamic nonlinear elastic behavior, nonequilibrium dynamics, first observed as a curiosity in earth materials has now been observed in a great variety of solids. The primary manifestations of the behavior are characteristic wave distortion, and slow dynamics, a recovery process to equilibrium that takes place linearly with the logarithm of time, over hours to days after a wave disturbance. The link between the diverse materials that exhibit nonequilibrium dynamics appears to be the presence of soft regions, thought to be 'damage' at many scales, ranging from order 10-9 m to 10-1 m at least. The regions of soft matter may be distributed as in a rock sample, or isolated, as in a sample with a single crack [LANLhttp://www.lanl.gov/orgs/ees/ees11/geophysics/nonlinear/nonlinear.shtml].

130 LPW 1000 Lm Warm White LED for Illumination  

SciTech Connect

An illumination-grade warm-white LED, having correlated color temperature (CCT) between 2700 and 3500 K and capable of producing 1000 lm output at over 130 lm/W at room temperature, has been developed in this program. The high-power warm-white LED is an ideal source for use in indoor and outdoor lighting applications. Over the two year period, we have made the following accomplishments: • Developed a low-cost high-power white LED package and commercialized a series of products with CCT ranging from 2700 to 5700 K under the product name LUXEON M; • Demonstrated a record efficacy of 124.8 lm/W at a flux of 1023 lm, CCT of 3435 K and color rendering index (CRI) over 80 at room temperature in the productized package; • Demonstrated a record efficacy of 133.1 lm/W at a flux of 1015 lm, CCT of 3475 K and CRI over 80 at room temperature in an R&D package. The new high-power LED package is a die-on-ceramic surface mountable LED package. It has four 2 mm2 InGaN pump dice, flip-chip attached to a ceramic submount in a 2x2 array configuration. The submount design utilizes a design approach that combines a high-thermal- conductivity ceramic core for die attach and a low-cost and low-thermal-conductivity ceramic frame for mechanical support and as optical lens carrier. The LED package has a thermal resistance of less than 1.25 K/W. The white LED fabrication also adopts a new batch level (instead of die-by-die) phosphor deposition process with precision layer thickness and composition control, which provides not only tight color control, but also low cost. The efficacy performance goal was achieved through the progress in following key areas: (1) high-efficiency royal blue pump LED development through active region design and epitaxial growth quality improvement (funded by internal programs); (2) improvement in extraction efficiency from the LED package through improvement of InGaN-die-level and package-level optical extraction efficiency; and (3) improvement in phosphor system efficiency by improving the lumen equivalent (LE) and phosphor package efficiency (PPE) through improvement in phosphor-package interactions. The high-power warm-white LED product developed has been proven to have good reliability through extensive reliability tests. The new kilo-lumen package has been commercialized under the product name LUXEON M. As of the end of the program, the LUXEON M product has been released in the following CCT/CRI combinations: 3000K/70, 4000K/70, 5000K/70, 5700K/70, 2700K/80, 3000K/80 and 4000K/80. LM-80 tests for the products with CCTs of 4000 K and higher have reached 8500 hours, and per IESNA TM-21-11 have established an L70 lumen maintenance value of >51,000 hours at A drive current and up to 120 °C board temperature.

Steady State Thermoelectric Field-Reversed Configurations  

Science Journals Connector (OSTI)

It is shown that the cross-field thermoelectric force of magnetized plasmas can maintain field-reversed configurations against resistive diffusion, resulting in a steady state device attractive for thermonuclear fusion. If a peaked radial temperature profile is maintained, the thermoelectric force is in the opposite direction to the usual resistive friction, thus maintaining the field configuration. The field maintenance is tantamount to dynamo action, operating even in two dimensions. We show that a steady state device can be made by simply heating the O-point: no external electric fields or particle sources are needed. The feasibility of this scheme for fusion is discussed.

Kinetic Stability of the Field Reversed Configuration  

SciTech Connect

New computational results are presented which advance the understanding of the stability properties of the Field-Reversed Configuration (FRC). The FRC is an innovative confinement approach that offers a unique fusion reactor potential because of its compact and simple geometry, translation properties, and high plasma beta. One of the most important issues is FRC stability with respect to low-n (toroidal mode number) MHD modes. There is a clear discrepancy between the predictions of standard MHD theory that many modes should be unstable on the MHD time scale, and the observed macroscopic resilience of FRCs in experiments.

Dielectric recombination and stability of warm gas in AGN  

SciTech Connect

High resolution ultraviolet and X-ray spectra show that material outflow occur from the close neighbourhoods of super-massive black holes in active galactic nuclei (AGN). The absorption features seen in the high resolution soft X-ray spectra is attributed to gas which is conventionally termed as the warm absorber (WA) and often the thermal equilibrium (stability) curve is used as a theoretical tool to offer insights into the nature of the WA. The shape of the stability curve is determined by factors like the spectral energy distribution of the ionizing flux and the chemical composition of the absorbing gas. We found that the stability curves obtained under the same set of assumptions for the prevalent physical conditions in the AGN environment, but using recently derived dielectronic recombination rates, give significantly different results from what is predicted with older atomic data. The variations in phase space region of the stability curves corresponding to WAs, lead to different physical predictions. The results obtained with the current dielectronic recombination rate coefficients are more reliable because the WA models along the stability curve have computed, updated coefficient values.

Equilibration processes in the Warm-Hot Intergalactic Medium  

E-Print Network (OSTI)

The Warm-Hot Intergalactic Medium (WHIM) is thought to contribute about 40-50 % to the baryonic budget at the present evolution stage of the universe. The observed large scale structure is likely to be due to gravitational growth of density fluctuations in the post-inflation era. The evolving cosmic web is governed by non-linear gravitational growth of the initially weak density fluctuations in the dark energy dominated cosmology. Non-linear structure formation, accretion and merging processes, star forming and AGN activity produce gas shocks in the WHIM. Shock waves are converting a fraction of the gravitation power to thermal and non-thermal emission of baryonic/leptonic matter. They provide the most likely way to power the luminous matter in the WHIM. The plasma shocks in the WHIM are expected to be collisionless. Collisionless shocks produce a highly non-equilibrium state with anisotropic temperatures and a large differences in ion and electron temperatures. We discuss the ion and electron heating by the collisionless shocks and then review the plasma processes responsible for the Coulomb equilibration and collisional ionisation equilibrium of oxygen ions in the WHIM. MHD-turbulence produced by the strong collisionless shocks could provide a sizeable non-thermal contribution to the observed Doppler parameter of the UV line spectra of the WHIM.

Top-Down Fragmentation of a Warm Dark Matter Filament  

E-Print Network (OSTI)

We present the first high-resolution n-body simulations of the fragmentation of dark matter filaments. Such fragmentation occurs in top-down scenarios of structure formation, when the dark matter is warm instead of cold. In a previous paper (Knebe et al. 2002, hereafter Paper I), we showed that WDM differs from the standard Cold Dark Matter (CDM) mainly in the formation history and large-scale distribution of low-mass haloes, which form later and tend to be more clustered in WDM than in CDM universes, tracing more closely the filamentary structures of the cosmic web. Therefore, we focus our computational effort in this paper on one particular filament extracted from a WDM cosmological simulation and compare in detail its evolution to that of the same CDM filament. We find that the mass distribution of the halos forming via fragmentation within the filament is broadly peaked around a Jeans mass of a few 10^9 Msun, corresponding to a gravitational instability of smooth regions with an overdensity contrast around 10 at these redshifts. Our results confirm that WDM filaments fragment and form gravitationally bound haloes in a top-down fashion, whereas CDM filaments are built bottom-up, thus demonstrating the impact of the nature of the dark matter on dwarf galaxy properties.

Testing DM warmness and quantity via the RRG model  

E-Print Network (OSTI)

We use the framework of a recently proposed model of reduced relativistic gas (RRG) to obtain the bounds for $\\Omega$'s of Dark Matter and Dark Energy (in the present case, a cosmological constant), taking into consideration an arbitrary warmness of Dark Matter. Two kind of tests are accounted for, namely the ones coming from the dynamics of the conformal factor of the homogeneous and isotropic metric and also the ones based on linear cosmic perturbations. The RRG model demonstrated its high effectiveness, permitting to explore a large volume in the space of mentioned parameters in a rather economic way. Taking all the tests together, namely Supernova type Ia (Union2 sample), $H(z)$, CMB ($R$ factor), BAO and LSS (2dfGRS data) into account, we confirm that $\\La$CDM is the most favored model. At the same time, for the 2dfGRS data alone we met the possibility of an alternative model with a very small quantity of a Dark Matter. This output is potentially relevant in view of the fact that the LSS is the only test...

The Energy Cascade from Warm Dark Matter Decays  

E-Print Network (OSTI)

We use a set of Monte Carlo simulations to follow the cascade produced by a primary electron of energy E_in in the intergalactic medium. We choose E_in=3-10 keV as expected from the decay of one of the most popular Warm Dark Matter (WDM) candidates, sterile neutrinos. Our simulation takes into account processes previously neglected such as free-free interactions with ions and recombinations and uses the best available cross sections for collisional ionizations and excitations with H and He and for electron-electron collisions. We precisely derive the fraction of the primary electron energy that heats the gas, ionizes atoms and produces line and continuum photons as a function of the ionization fraction. Handy fitting formulae for all the above energy depositions are provided. By keeping track of the individual photons we can distinguish between photons in the Ly-alpha resonance and those with energy E gas. This separation is important because a Ly-alpha background can heat or cool the gas depending on the nature of the photons, and can have effects on the 21 cm radiation emitted by neutral H, which will probably become detectable at z > 6 in the near future by the next generation radio interferometers.

Warmth Elevating the Depths: Shallower Voids with Warm Dark Matter  

E-Print Network (OSTI)

Warm dark matter (WDM) has been proposed as an alternative to cold dark matter (CDM), to resolve issues such as the apparent lack of satellites around the Milky Way. Even if WDM is not the answer to observational issues, it is essential to constrain the nature of the dark matter. The effect of WDM on haloes has been extensively studied, but the small-scale initial smoothing in WDM also affects the present-day cosmic web and voids. It suppresses the cosmic "sub-web" inside voids, and the formation of both void haloes and subvoids. In N-body simulations run with different assumed WDM masses, we identify voids with the zobov algorithm, and cosmic-web components with the origami algorithm. As dark-matter warmth increases, the initial-conditions smoothing increases, and the number of voids and subvoids is suppressed. Also, void density profiles change, their shapes become flatter inside the void radius, while edges of the voids remain unchanged. Also, filaments and walls become cleaner, as the sub-structures in be...

The First Billion Years of a Warm Dark Matter Universe  

E-Print Network (OSTI)

We present results of cosmological N-body hydrodynamic chemistry simulations of primordial structure growth and evolution in a scenario with warm dark matter (WDM) having a mass of 3keV and compare with a model consisting of standard cold dark matter (CDM). We focus on the high-redshift universe ($z>6$), where the structure formation process should better reflect the primordial (linear) differences in terms of matter power spectrum. We find that early epochs are exceptional probes of the dark-matter nature. Non-linear CDM and WDM power spectra differ by up to 2 dex at early times and show spreads of factor of a few persisting in the whole first Gyr. Primordial WDM objects with masses $\\lesssim 10^8\\,\\rm M_\\odot$ are less abundant by $\\gtrsim 1\\,\\rm dex$, both in terms of dark matter and of baryon content. Runaway molecular cooling in primordial WDM mini-haloes results severely inhibited due to the damping of power at large $k$ modes.

Global Stability of the Field Reversed Configuration  

SciTech Connect

New computational results are presented which provide a theoretical basis for the stability of the Field Reversed Configuration (FRC). The FRC is a compact toroid with negligible toroidal field in which the plasma is confined by a poloidal magnetic field associated with toroidal diamagnetic current. Although many MHD modes are predicted to be unstable, FRCs have been produced successfully by several formation techniques and show surprising macroscopic resilience. In order to understand this discrepancy, we have developed a new 3D nonlinear hybrid code (kinetic ions and fluid electrons), M3D-B, which is used to study the role of kinetic effects on the n = 1 tilt and higher n modes in the FRC. Our simulations show that there is a reduction in the tilt mode growth rate in the kinetic regime, but no absolute stabilization has been found for s bar less than or approximately equal to 1, where s bar is the approximate number of ion gyroradii between the field null and the separatrix. However, at low values of s bar, the instabilities saturate nonlinearly through a combination of a lengthening of the initial equilibrium and a modification of the ion distribution function. These saturated states persist for many Alfven times, maintaining field reversal.

A test refrigerator based on the modified Reverse Brayton cycle has been developed in the Chinese Academy of Sciences recently. To study the behaviors of this test refrigerator, a dynamic simulation has been carried out. The numerical model comprises the typical components of the test refrigerator: compressor, valves, heat exchangers, expander and heater. This simulator is based on the oriented-object approach and each component is represented by a set of differential and algebraic equations. The control system of the test refrigerator is also simulated, which can be used to optimize the control strategies. This paper describes all the models and shows the simulation results. Comparisons between simulation results and experimental data are also presented. Experimental validation on the test refrigerator gives satisfactory results.

Direct observation of time reversal violation  

SciTech Connect

A direct evidence for Time Reversal Violation (TRV) means an experiment that, considered by itself, clearly shows TRV independent of, and unconnected to, the results for CP Violation. No existing result before the recent BABAR experiment with entangled neutral B mesons had demonstrated TRV in this sense. There is a unique opportunity for a search of TRV with unstable particles thanks to the Einstein-Podolsky-Rosen (EPR) Entanglement between the two neutral mesons in B, and PHI, Factories. The two quantum effects of the first decay as a filtering measurement and the transfer of information to the still living partner allow performing a genuine TRV asymmetry with the exchange of 'in' and 'out' states. With four independent TRV asymmetries, BABAR observes a large deviation of T-invariance with a statistical significance of 14 standard deviations, far more than needed to declare the result as a discovery. This is the first direct observation of TRV in the time evolution of any system.

Control of magnetization reversal in oriented strontium ferrite thin films  

SciTech Connect

Oriented Strontium Ferrite films with the c axis orientation were deposited with varying oxygen partial pressure on Al{sub 2}O{sub 3}(0001) substrate using Pulsed Laser Deposition technique. The angle dependent magnetic hysteresis, remanent coercivity, and temperature dependent coercivity had been employed to understand the magnetization reversal of these films. It was found that the Strontium Ferrite thin film grown at lower (higher) oxygen partial pressure shows Stoner-Wohlfarth type (Kondorsky like) reversal. The relative importance of pinning and nucleation processes during magnetization reversal is used to explain the type of the magnetization reversal with different oxygen partial pressure during growth.

Energy-efficient reverse osmosis desalination process  

Science Journals Connector (OSTI)

Abstract A novel energy-efficient reverse osmosis (EERO) process is proposed for which the retentate from single-stage reverse osmosis (SSRO) serves as the feed to a countercurrent membrane cascade with recycle (CMCR). The 3-stage EERO process employs two, whereas the 4-stage EERO process employs three stages in the CMCR. The EERO process is advantageous because of four features: (i) coupling SSRO with a CMCR; (ii) countercurrent retentate and permeate flow; (iii) permeate recycling; and (iv) retentate self-recycling owing to the use of one or more nanofiltration stages. The EERO process was compared to conventional SSRO for both processes operating at the thermodynamic limit and employing an energy-recovery device. For the same overall recovery the osmotic pressure differential is reduced by 33% and 50% relative to SSRO for the 3- and 4-stage ERRO processes, respectively. There is a critical recovery above which the EERO process also can reduce the specific energy consumption (SEC) relative to SSRO for the same recovery. For a typical seawater feed of 35 g/L the 3-stage EERO process can achieve a 75% recovery at a net SEC of 2.746 kWh/m3, an 11.0% reduction in the SEC relative to SSRO for the same recovery. The 4-stage EERO process can achieve a 75% recovery at the same net SEC as SSRO (3.086 kWh/m3). Accounting for the additional membrane area required for the EERO process increases its cost relative to that for SSRO by at most 8%. An additional benefit of the EERO process relative to SSRO is the highly concentrated retentate that reduces the brine disposal volume or can be used to greatly increase the draw potential to harvest its osmotic potential energy via the pressure-retarded osmosis process.

On modification of global warming by sulfate aerosols  

SciTech Connect

There is increasing evidence that the response of climate to increasing greenhouse gases may be modified by accompanying increases in sulfate aerosols. In this study, the patterns of response in the surface climatology of a coupled ocean-atmosphere general circulation model forced by increases in carbon dioxide alone is compared with those obtained by increasing carbon dioxide and aerosol forcing. The simulations are run from early industrial times using the estimated historical forcing and continued to the end of the twenty-first century assuming a nonintervention emissions scenario for greenhouse gases and aerosols. The comparison is made for the period 2030-2050 when the aerosol forcing is a maximum. In winter, the cooling due to aerosols merely tends to reduce the response to carbon dioxide, whereas in summer, it weakens the monsoon circulations and reverses some of the changes in the hydrological cycle on increasing carbon dioxide. This response is in some respects similar to that found in simulations with changed orbital parameters, as between today and the middle Holocene. The hydrological response in the palaeosimulations is supported by palaeoclimatic reconstructions. The results of changes in aerosol concentrations of the magnetic projected in the scenarios would have a major effect on regional climate, especially over Europe and Southeast Asia. 74 refs., 12 figs., 6 tabs.

Natural gas and efficient technologies: A response to global warming  

SciTech Connect

It has become recognized by the international scientific community that global warming due to fossil fuel energy buildup of greenhouse CO{sub 2} in the atmosphere is a real environmental problem. Worldwide agreement has also been reached to reduce CO{sub 2} emissions. A leading approach to reducing CO{sub 2} emissions is to utilize hydrogen-rich fuels and improve the efficiency of conversion in the power generation, transportation and heating sectors of the economy. In this report, natural gas, having the highest hydrogen content of all the fossil fuels, can have an important impact in reducing CO{sub 2} emissions. This paper explores natural gas and improved conversion systems for supplying energy to all three sectors of the economy. The improved technologies include combined cycle for power generation, the Carnol system for methanol production for the transportation sector and fuel cells for both power generation and transportation use. The reduction in CO{sub 2} from current emissions range from 13% when natural gas is substituted for gasoline in the transportation sector to 45% when substituting methanol produced by the Carnol systems (hydrogen from thermal decomposition of methane reacting with CO{sub 2} from coal-fired power plants) used in the transportation sector. CO{sub 2} reductions exceeding 60% can be achieved by using natural gas in combined cycle for power generation and Carnol methanol in the transportation sector and would, thus, stabilize CO{sub 2} concentration in the atmosphere predicted to avoid undue climate change effects. It is estimated that the total fossil fuel energy bill in the US can be reduced by over 40% from the current fuel bill. This also allows a doubling in the unit cost for natural gas if the current energy bill is maintained. Estimates of the total net incremental replacement capital cost for completing the new improved equipment is not more than that which will have to be spent to replace the existing equipment conducting business as usual.

Tests of time reversal in neutron?nucleus scattering  

Science Journals Connector (OSTI)

Experiments to test time?reversal invariance are discussed. The experiments are based on observables constructed from the momentum and spin vectors of epithermal neutrons and from the spin of an aligned or polarized target. It is shown that the proposed tests are detailed balance tests of time?reversal invariance. The status of the experiments is briefly reviewed.

Synthesis of the Optimal 4-bit Reversible Circuits  

E-Print Network (OSTI)

Optimal synthesis of reversible functions is a non-trivial problem. One of the major limiting factors in computing such circuits is the sheer number of reversible functions. Even restricting synthesis to 4-bit reversible functions results in a huge search space (16!~2^44 functions). The output of such a search alone, counting only the space required to list Toffoli gates for every function, would require over 100 terabytes of storage. In this paper, we present an algorithm that synthesizes an optimal circuit for any 4-bit reversible specification. We employ several techniques to make the problem tractable. We report results from several experiments, including synthesis of random 4-bit permutations, optimal synthesis of all 4-bit linear reversible circuits, synthesis of existing benchmark functions, and distribution of optimal circuits. Our results have important implications for the design and optimization of quantum circuits, testing circuit synthesis heuristics, and performing experiments in the area of quantum information processing.

Linear multistep methods for integrating reversible differential equations  

E-Print Network (OSTI)

This paper studies multistep methods for the integration of reversible dynamical systems, with particular emphasis on the planar Kepler problem. It has previously been shown by Cano & Sanz-Serna that reversible linear multisteps for first-order differential equations are generally unstable. Here, we report on a subset of these methods -- the zero-growth methods -- that evade these instabilities. We provide an algorithm for identifying these rare methods. We find and study all zero-growth, reversible multisteps with six or fewer steps. This select group includes two well-known second-order multisteps (the trapezoidal and explicit midpoint methods), as well as three new fourth-order multisteps -- one of which is explicit. Variable timesteps can be readily implemented without spoiling the reversibility. Tests on Keplerian orbits show that these new reversible multisteps work well on orbits with low or moderate eccentricity, although at least 100 steps/radian are required for stability.

Plant experience with temporary reverse osmosis makeup water systems  

SciTech Connect

Pacific Gas and Electric (PG and E) Company's Diablo Canyon Power Plant (DCPP), which is located on California's central coast, has access to three sources of raw water: creek water, well water, and seawater. Creek and well water are DCPP's primary sources of raw water; however, because their supply is limited, these sources are supplemented with seawater. The purpose of this paper is to discuss the temporary, rental, reverse osmosis systems used by PG and E to process DCPP's raw water into water suitable for plant makeup. This paper addresses the following issues: the selection of reverse osmosis over alternative water processing technologies; the decision to use vendor-operated temporary, rental, reverse osmosis equipment versus permanent PG and E-owned and -operated equipment; the performance of DCPP's rental reverse osmosis systems; and, the lessons learned from DCPP's reverse osmosis system rental experience that might be useful to other plants considering renting similar equipment.

BIMETALLIC LITHIUM BOROHYDRIDES TOWARD REVERSIBLE HYDROGEN STORAGE  

SciTech Connect

Borohydrides such as LiBH{sub 4} have been studied as candidates for hydrogen storage because of their high hydrogen contents (18.4 wt% for LiBH{sub 4}). Limited success has been made in reducing the dehydrogenation temperature by adding reactants such as metals, metal oxides and metal halides. However, full rehydrogenation has not been realized because of multi-step decomposition processes and the stable intermediate species produced. It is suggested that adding second cation in LiBH{sub 4} may reduce the binding energy of B-H. The second cation may also provide the pathway for full rehydrogenation. In this work, several bimetallic borohydrides were synthesized using wet chemistry, high pressure reactive ball milling and sintering processes. The investigation found that the thermodynamic stability was reduced, but the full rehydrogenation is still a challenge. Although our experiments show the partial reversibility of the bimetallic borohydrides, it was not sustainable during dehydriding-rehydriding cycles because of the accumulation of hydrogen inert species.

Liquid suspensions of reversible metal hydrides  

DOE Patents (OSTI)

The reversibility of the process M + x/2 H/sub 2/ ..-->.. MH/sub x/, where M is a metal hydride former that forms a hydride MH/sub x/ in the presence of H/sub 2/, generally used to store and recall H/sub 2/, is found to proceed under a liquid, thereby to reduce contamination, provide better temperature control and provide in situ mobility of the reactants. Thus, a slurry of particles of a metal hydride former with an inert solvent is subjected to temperature and pressure controlled atmosphere containing H/sub 2/, to store hydrogen (at high pressures) and to release (at low pressures) previously stored hydrogen. The direction of the flow of the H/sub 2/ through the liquid is dependent upon the H/sub 2/ pressure in the gas phase at a given temperature. When the former is above the equilibrium absorption pressure of the respective hydride the reaction proceeds to the right, i.e., the metal hydride is formed and hydrogen is stored in the solid particle. When the H/sub 2/ pressure in the gas phase is below the equilibrium dissociation pressure of the respective hydride the reaction proceeds to the left, the metal hydride is decomposed and hydrogen is released into the gas phase.

POLAR FIELD REVERSAL OBSERVATIONS WITH HINODE  

SciTech Connect

We have been monitoring yearly variation in the Sun's polar magnetic fields with the Solar Optical Telescope aboard Hinode to record their evolution and expected reversal near the solar maximum. All magnetic patches in the magnetic flux maps are automatically identified to obtain the number density and magnetic flux density as a function of the total magnetic flux per patch. The detected magnetic flux per patch ranges over four orders of magnitude (10{sup 15}-10{sup 20} Mx). The higher end of the magnetic flux in the polar regions is about one order of magnitude larger than that of the quiet Sun, and nearly that of pores. Almost all large patches ({>=}10{sup 18} Mx) have the same polarity, while smaller patches have a fair balance of both polarities. The polarity of the polar region as a whole is consequently determined only by the large magnetic concentrations. A clear decrease in the net flux of the polar region is detected in the slow rising phase of the current solar cycle. The decrease is more rapid in the north polar region than in the south. The decrease in the net flux is caused by a decrease in the number and size of the large flux concentrations as well as the appearance of patches with opposite polarity at lower latitudes. In contrast, we do not see temporal change in the magnetic flux associated with the smaller patches (<10{sup 18} Mx) and that of the horizontal magnetic fields during the years 2008-2012.

Durability Evaluation of Reversible Solid Oxide Cells  

SciTech Connect

An experimental investigation on the performance and durability of single solid oxide cells (SOCs) is under way at the Idaho National Laboratory. Reversible operation of SOCs includes electricity generation in the fuel cell mode and hydrogen generation in the electrolysis mode. Degradation is a more significant issue when operating SOCs in the electrolysis mode. In order to understand and mitigate the degradation issues in high temperature electrolysis, single SOCs with different configurations from several manufacturers have been evaluated for initial performance and long-term durability. A new test apparatus for single cell and small stack tests has been developed for this purpose. Cells were obtained from four industrial partners. Cells from Ceramatec Inc. and Materials and Systems Research Inc. (MSRI) showed improved durability in electrolysis mode compared to previous stack tests. Cells from Saint Gobain Advanced Materials Inc. (St. Gobain) and SOFCPower Inc. demonstrated stable performance in the fuel cell mode, but rapid degradation in the electrolysis mode, especially at high current density. Electrolyte-electrode delamination was found to have a significant impact on degradation in some cases. Enhanced bonding between electrolyte and electrode and modification of the electrode microstructure helped to mitigate degradation. Polarization scans and AC impedance measurements were performed during the tests to characterize cell performance and degradation.

In 1972, I joined the Livermore ICF Theory and Target Design group led by John Nuckolls, shortly after publication of John`s seminal Nature article on ICF. My primary role, working with others in the target design program including Mordy Rosen, Steve Haan, and Larry Suter, has been as a target designer and theorist who utilized the LASNEX code to perform numerical experiments, which along with analysis of laboratory and underground thermonuclear experiments allowed me to develop a series of models and physical insights which have been used to set the direction and priorities of the Livermore program. I have had the good fortune of working with an outstanding team of scientists who have established LLNL as the premier ICF laboratory in the world. John Emmett and the LLNL Laser Science team were responsible for developing a series of lasers from Janus to Nova which have given LLNL unequaled facilities. George Zimmerman and the LASNEX group developed the numerical models essential for projecting future performance and requirements as well as for designing and analyzing the experiments. Bill Kruer, Bruce Langdon and others in the plasma theory group developed the fundamental understanding of laser plasma interactions which have played such an important role in ICF. And a series of experiment program leaders including Mike Campbell and Joe Kilkenny and their laser experimental teams developed the experimental techniques and diagnostic capabilities which have allowed us to c increasingly complex and sophisticated experiments.

Global warming and end-use efficiency implications of replacing CFCs  

SciTech Connect

The direct contribution of CFCs to calculated global warming has been recognized for some time. As a result of the international agreement to phase out CFCs due to stratospheric ozone and the ensuing search for suitable alternatives, there has recently been increased attention on the DIRECT global warming potential (GWP) of the fluorocarbon alternatives as greenhouse gases. However, to date there has been little focus on the INDIRECT global warming effect arising from end-use efficiency changes and associated CO{sub 2} emissions. A study being conducted at Oak Ridge National Laboratory (ORNL) addresses this combined or total global warming impact of viable options to replace CFCs in their major energy-related applications. This paper reviews selected results for air-conditioning, refrigeration, and heat pump applications. The analysis indicates that the CFC user industries have made substantial progress in approaching near-equal energy efficiency with the HCFC/HFC alternative refrigerants. The findings also bring into question the relative importance of the DIRECT (chemical-related) effect in many applications. Replacing CFCs is an important step in reducing the total global warming impact, and at present the HCFC and HFCS appear to offer the best efficiency and lowest total impact of options available in the relatively short time period required for the transition away from CFCs.

The influence of climate change and the timing of stratospheric warmings on Arctic ozone depletion  

SciTech Connect

A three-dimensional model is presented to evaluate the influence of climatic change and increased carbon dioxide concentrations on ozone depletion in the Arctic region. Satellite data showing the time of stratospheric warmings during the winters of 1979-1992 is used in a series of idealized experiments where the timing of the warmings is varied by using different geopotential wave amplitudes. Results of the experiments indicate that for doubled atmospheric carbon dioxide levels, an ozone hole in the Arctic is more likely to develop during years where late stratospheric warming has occurred after a relatively quiescent winter. The validity of this model is dependent on the future composition and temperature of the stratosphere. 43 refs., 21 figs.

Potential enhancement of warm X-ray dose from a reflexing bremsstrahlung diode  

SciTech Connect

The potential for generating intense bursts of warm x rays (20 to 60 keV) using electron reflexing diodes on pulsed-power accelerators is evaluated with the TIGER Monte Carlo code, showing that hundreds of kilojoules of warm x rays can be generated under idealized conditions, for a Jupiter (60-MA, 5-MV, 100-ns) class accelerator. The calculations are compared with data from Gamble-II experiments and applied to two suggested Jupiter diode configurations. If the simultaneous irradiation from the high-energy tail of the bremsstrahlung, which accompanies the warm x rays, is a concern then the reflexing technique is shown to be limited to the irradiation of targets thinner than {approximately}400 {mu}m for low-Z targets like aluminum and thinner than {approximately}5 {mu}m for high-Z targets like gold.

In this study, researchers from Argonne, Northern Illinois University, and The University of Pennsylvania have demonstrated that the chemical environment can control the polarization orientation in an ultrathin ferroelectric film. This is complementary to recent predictions that polarization can affect surface chemistry and illuminates potential applications in sublithographic patterning and electrically tunable catalysts. In situ synchrotron X-ray scattering measurements showed that high or low

Biphase turbine for reverse osmosis desalination. Final report  

SciTech Connect

A new hydraulic reaction turbine was designed to recover the power available in the high-pressure waste-brine stream of reverse osmosis desalination systems. A reaction turbine sized for reverse-osmosis systems producing 600 gph was built and tested. The turbine performed well driving either a variable-speed pump or an electrical generator. Measured turbine efficiency (shaft power divided by available power) was 63%, compared with a prediction of 67%. The turbine can be built with larger capacity to reduce the size, weight and power consumption of reverse osmosis desalination systems. Efficiency of larger units is predicted to lie in the range of 65 to 70%.

Removal of radionuclides in drinking water by membrane treatment using ultrafiltration, reverse osmosis and electrodialysis reversal  

Science Journals Connector (OSTI)

A pilot plant had been built to test the behaviour of ultrafiltration (UF), reverse osmosis (RO), and electrodialysis reversal (EDR) in order to improve the quality of the water supplied to Barcelona metropolitan area from the Llobregat River. This paper presents results from two studies to reduce natural radioactivity. The results from the pilot plant with four different scenarios were used to design the full-scale treatment plant built (SJD WTP). The samples taken at different steps of the treatment were analysed to determine gross alpha, gross beta and uranium activity. The results obtained revealed a significant improvement in the radiological water quality provided by both membrane techniques (RO and EDR showed removal rates higher than 60%). However, UF did not show any significant removal capacity for gross alpha, gross beta or uranium activities. RO was better at reducing the radiological parameters studied and this treatment was selected and applied at the full scale treatment plant. The RO treatment used at the SJD WTP reduced the concentration of both gross alpha and gross beta activities and also produced water of high quality with an average removal of 95% for gross alpha activity and almost 93% for gross beta activity at the treatment plant.

U.S. Energy Information Administration (EIA) Indexed Site

More U.S. households burning wood this winter to stay warm, More U.S. households burning wood this winter to stay warm, reversing two-decade decline Burning wood as the primary heating source in U.S. households has risen over the last 10 years, reversing the decline seen in the 1980s and 1990s. About 2.6 million households out of 115 million will rely on wood as the main way to warm their homes this winter. That's up 3 percent from last year, according to the U.S. Energy Information Administration's new winter fuels forecast. The West will have the most households using wood as their primary space heating fuel, followed by the Midwest, South and Northeast regions of the United States. Wood is also the second most common backup fuel, after electricity, that households across the U.S. use as a supplemental heating source. Almost half of all rural households use wood this

Iowa's first electrodialysis reversal water treatment plant  

Science Journals Connector (OSTI)

In 1979 the City of Washington was notified by the Iowa Department of Natural Resources (IDNR) that the City was in violation of the radium standard for drinking water. The City of Washington authorized an engineering study to determine the most cost-effective and practical way to remove radium and, at the same time, improve overall water quality. Several possible treatment alternatives were evaluated. It was finally decided to utilize electrodialysis reversal (EDR). Washington obtains its water from three deep wells ranging in capacity from 600–780 gpm. The untreated water withdrawn from the wells first passes through the EDR units. There are three EDR units, each able to produce 285 gpm of finished water. In the future, another EDR unit can be easily added to the other three units, since the new plant was built and plumbed for an additional EDR unit if water demand increased. The Jordan aquifer supply is adequate for current and future needs. The average daily water usage in 1993 was 818,000 gal/d. In order to meet peak flows, it is possible to bypass the EDR units with part of the untreated water and then blend treated and untreated water. The treated water meets IDNR standards of 5.0 pC/L. After the EDR units, the water flows through an aerator where odor-causing gases and carbon dioxide are removed. Aeration reduces the amount of caustic soda and chlorine used in the finished water. The hydrogen sulfide gas leaves the water as it passes through the aerator, and this loss of gas creates less chlorine demand. Total and free chlorine residuals are now detected in every water main of the town, whereas before, the residuals would not be detected in certain area of Washington. Phosphates have been cut back from 7 pounds per day to one pound per day. Better water quality is now being achieved with fewer chemicals added to the finished water. Washington's water treatment plant is the first municipal EDR plant in the State of Iowa and one of the largest municipal installations in the United States.

Reverse logistics network design for spent batteries: a simulation study  

Science Journals Connector (OSTI)

End of life (EOL) product management, which encompasses reuse, remanufacturing and materials recycling, requires a structured reverse logistic network in order to collect products efficiently at the end of their life cycle. This work describes modelling and simulation of reverse logistics network design for collection of spent batteries for Sangrur District of North India. To compare different order assignment, a simulation model of forward and reverse logistics networks has been developed. Several simulation experiments have been designed to analyse impact of the system design factors on the operational performance of the reverse logistics system. The simulation results show that the model presented in this paper calculates the battery collection cost, transfer time, transfer cost, and resource utilisation in a predictable manner. Moreover, it provides a tool to understand how the system behaves by carrying out 'what-if' assessments and to identify which parameters are most important for more detailed analysis.

The benefits of hybridising electrodialysis with reverse osmosis  

Science Journals Connector (OSTI)

Abstract A cost analysis reveals that hybridisation of electrodialysis with reverse osmosis is only justified if the cost of water from the reverse osmosis unit is less than 40% of that from a stand-alone electrodialysis system. In such cases the additional reverse osmosis costs justify the electrodialysis cost savings brought about by shifting salt removal to higher salinity, where current densities are higher and equipment costs lower. Furthermore, the analysis suggests that a simple hybrid configuration is more cost effective than a recirculated hybrid, a simple hybrid being one where the reverse osmosis concentrate is fed to the electrodialysis stack and the products from both units are blended, and a recirculated being one hybrid involving recirculation of the electrodialysis product back to the reverse osmosis unit. The underlying rationale is that simple hybridisation shifts salt removal away from the lowest salinity zone of operation, where salt removal is most expensive. Further shifts in the salinity at which salt is removed, brought about by recirculation, do not justify the associated increased costs of reverse osmosis.

WARM EXTENDED DENSE GAS AT THE HEART OF A COLD COLLAPSING DENSE CORE  

SciTech Connect

In order to investigate when and how the birth of a protostellar core occurs, we made survey observations of four well-studied dense cores in the Taurus molecular cloud using CO transitions in submillimeter bands. We report here the detection of unexpectedly warm (approx30-70 K), extended (radius of approx2400 AU), dense (a few times 10{sup 5} cm{sup -3}) gas at the heart of one of the dense cores, L1521F (MC27), within the cold dynamically collapsing components. We argue that the detected warm, extended, dense gas may originate from shock regions caused by collisions between the dynamically collapsing components and outflowing/rotating components within the dense core. We propose a new stage of star formation, 'warm-in-cold core stage (WICCS)', i.e., the cold collapsing envelope encases the warm extended dense gas at the center due to the formation of a protostellar core. WICCS would constitute a missing link in evolution between a cold quiescent starless core and a young protostar in class 0 stage that has a large-scale bipolar outflow.
