www.elsevier.com/locate/jue Poverty and crime in 19th century Germany  

E-Print Network (OSTI)

We estimate the impact of poverty on crime in 19th century Bavaria, Germany. Rainfall is used as an instrumental variable for grain (rye) prices to address econometric identification problems in the existing literature. The rye price was a major determinant of living standards during this period. The rye price has a positive effect on property crime: a one standard deviation increased property crime by 8%. OLS estimates are twice as large as instrumental variable estimates, highlighting the value of our empirical approach. Higher rye prices lead to significantly less violent crime, though, and we argue that higher beer prices, caused by the higher rye prices, are a likely explanation.

PERIASTRON PASSAGE TRIGGERING OF THE 19TH CENTURY ERUPTIONS OF ETA CARINAE  

Science Conference Proceedings (OSTI)

We reconstruct the evolution of {eta} Car in the last two centuries under the assumption that the two 19th century eruptions were triggered by periastron passages and through this reconstruction constrain the binary parameters. The beginning of the lesser eruption (LE) at the end of the 19th century occurred when the system was very close to periastron passage, suggesting that the secondary triggered the LE. We assume that the 1838-1858 great eruption (GE) was triggered by a periastron passage as well. We also assume that mass transferred from the primary to the secondary star accounts for the extra energy of the GE. With these assumptions we constrain the total mass of the binary system to be M = M{sub 1} + M{sub 2} {approx}> 250 M{sub sun}. These higher than commonly used masses better match the observed luminosity with stellar evolutionary tracks. Including mass loss by the two stars and mass transfer from the primary to the secondary we obtain a good match of periastron passages to the two peaks in the light curve of the GE. Based on these findings and a similar behavior of P Cygni, we speculate that major luminous blue variable eruptions are triggered by stellar companions and that in extreme cases a short duration event with a huge mass transfer rate can lead to a bright transient event on timescales of weeks to months (a 'supernova impostor').

21st century advanced hydropower turbine system  

DOE Green Energy (OSTI)

While hydropower turbine manufacturers have incrementally improved turbine technology to increase efficiency, the basic design concepts haven`t changed for decades. These late 19th and early 20th century designs did not consider environmental effects, since little was known about environmental effects of hydropower at the time. The U.S. Department of Energy (DOE) and the hydropower industry recognize that hydropower plants have an effect on the environment and there is a great need to bring turbine designs into the 21st century. DOE has issued a request for proposals (RFP) that requested proposers to discard conventional thinking, search out innovative solutions, and to visualize innovative turbines designed from a new perspective. This perspective would look at the {open_quotes}turbine system{close_quotes} (intake to tailrace) which will balance environmental, technical, and economic considerations. This paper describes the DOE Advanced Hydropower Turbine System Program.

SUMMARY REPORT OF THE DOE DIRECT LIQUEFACTION PROCESS DEVELOPMENT CAMPAIGN OF THE LATE TWENTIETH CENTURY  

SciTech Connect

Following the petroleum price and supply disruptions of 1973, the U.S. government began a substantial program to fund the development of alternative fuels. Direct coal liquefaction was one of the potential routes to alternative fuels. The direct coal liquefaction program was funded at substantial levels through 1982, and at much lower levels thereafter. Those processes that were of most interest during this period were designed to produce primarily distillate fuels. By 1999, U.S. government funding for the development of direct coal liquefaction ended. Now that the end of this campaign has arrived, it is appropriate to summarize the process learnings derived from it. This report is a summary of the process learnings derived from the DOE direct coal liquefaction process development campaign of the late twentieth century. The report concentrates on those process development programs that were designed to produce primarily distillate fuels and were largely funded by DOE and its predecessors in response to the petroleum supply and price disruptions of the 1970s. The report is structured as chapters written by different authors on most of the major individual DOE-funded process development programs. The focus of the report is process learnings, as opposed to, say, fundamental coal liquefaction science or equipment design. As detailed in the overview (Chapter 2), DOE's direct coal liquefaction campaign made substantial progress in improving the process yields and the quality of the distillate product. Much of the progress was made after termination by 1983 of the major demonstration programs of the ''first generation'' (SRC-II, H-Coal, EDS) processes.

Western Ledge Reef Wreck: The Analysis and Reconstruction of the Late 16th-Century Ship of the Spanish Empire  

E-Print Network (OSTI)

The Western Ledge Reef Wreck, discovered and later excavated in Bermuda between 1989 and 1991, is a prime example of Iberian shipbuilding within a broader Atlantic context. Operating during the late 16th-century, arguably one of the most fascinating periods of Spanish maritime history, the ship epitomizes the culture and technology identified with the celebrated fleets of the Carrera de Indias. By combining the new and previously unavailable data with that of the original reports, this dissertation outlines the structural details of this small utilitarian vessel which plowed the Atlantic Ocean between Spain and the Spanish America. Regarded as one of the better preserved Iberian shipwrecks in the New World, the hull timbers were disassembled and raised to the surface for detailed recording and analysis; the most comprehensive being the study and reconstruction presented in this dissertation. This data not only illustrates the transition from late medieval ship construction founded on the unempirical and intuitive style of local shipwrights to that of the geometrically- and scientific-rooted Renaissance design philosophy, but also to a frame-led assembly sequence. The hull remains and associated cultural material excavated from the site prove to be an important 16th- and 17th-century collection of Spanish and New World origin, which collectively reinforce the notion that the Western Ledge Reef Wreck was on its homebound course when it sunk among treacherous Bermuda reefs sometime between 1560 and 1600.

This document is a report of observations and results obtained from a lighting demonstration project conducted under the U.S. Department of Energy (DOE) GATEWAY Demonstration Program. The program supports demonstrations of high-performance solid-state lighting (SSL) products in order to develop empirical data and experience with in-the-field applications of this advanced lighting technology. The DOE GATEWAY Demonstration Program focuses on providing a source of independent, third-party data for use in decision-making by lighting users and professionals; this data should be considered in combination with other information relevant to the particular site and application under examination. Each GATEWAY Demonstration compares SSL products against the incumbent technologies used in that location. Depending on available information and circumstances, the SSL product may also be compared to alternate lighting technologies. Though products demonstrated in the GATEWAY program may have been prescreened for performance, DOE does not endorse any commercial product or in any way guarantee that users will achieve the same results through use of these products. This report reviews the installation and use of LED PAR38 lamps to light a collection of toned albument photographic prints at the J. Paul Getty Museum in Malibu, California. Research results provided by the Getty Conservation Institute are incorporated and discussed.

The 19th Avenue Landfill is an National Priorities List site located in Maricopa County, Phoenix, Arizona. The site was operated as a sanitary landfill between 1957 and 1979. Most of the waste disposed of at the landfill was from municipal sources; however, old gasoline storage tanks, radioactive waste, hospital waste, industrial waste, and old transformers were also landfilled. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via ingestion, dermal contact, or inhalation of contaminants in subsurface soil and refuse, soil-gas, and air.

Inter-annual Tropospheric Aerosol Variability in Late Twentieth Century and its Impact on Tropical Atlantic and West African Climate by Direct and Semi-direct Effects  

Science Conference Proceedings (OSTI)

A new high-resolution (0.9$^{\\circ}$x1.25$^{\\circ}$ in the horizontal) global tropospheric aerosol dataset with monthly resolution is generated using the finite-volume configuration of Community Atmosphere Model (CAM4) coupled to a bulk aerosol model and forced with recent estimates of surface emissions for the latter part of twentieth century. The surface emissions dataset is constructed from Coupled Model Inter-comparison Project (CMIP5) decadal-resolution surface emissions dataset to include REanalysis of TROpospheric chemical composition (RETRO) wildfire monthly emissions dataset. Experiments forced with the new tropospheric aerosol dataset and conducted using the spectral configuration of CAM4 with a T85 truncation (1.4$^{\\circ}$x1.4$^{\\circ}$) with prescribed twentieth century observed sea surface temperature, sea-ice and greenhouse gases reveal that variations in tropospheric aerosol levels can induce significant regional climate variability on the inter-annual timescales. Regression analyses over tropical Atlantic and Africa reveal that increasing dust aerosols can cool the North African landmass and shift convection southwards from West Africa into the Gulf of Guinea in the spring season in the simulations. Further, we find that increasing carbonaceous aerosols emanating from the southwestern African savannas can cool the region significantly and increase the marine stratocumulus cloud cover over the southeast tropical Atlantic ocean by aerosol-induced diabatic heating of the free troposphere above the low clouds. Experiments conducted with CAM4 coupled to a slab ocean model suggest that present day aerosols can shift the ITCZ southwards over the tropical Atlantic and can reduce the ocean mixed layer temperature beneath the increased marine stratocumulus clouds in the southeastern tropical Atlantic.

In the century since Einstein's anno mirabilis of 1905, our concept of the Universe has expanded from Kapteyn's flattened disk of stars only 10 kpc across to an observed horizon about 30 Gpc across that is only a tiny fraction of an immensely large inflated bubble. The expansion of our knowledge about the Universe, both in the types of data and the sheer quantity of data, has been just as dramatic. This talk will summarize this century of progress and our current understanding of the cosmos.

426 JOURNAL OF CLIMATE VOLUME 16 Solar and Greenhouse Gas Forcing and Climate Response in the Twentieth Century  

E-Print Network (OSTI)

Ensemble experiments with a global coupled climate model are performed for the twentieth century with time-evolving solar, greenhouse gas, sulfate aerosol (direct effect), and ozone (tropospheric and stratospheric) forcing. Observed global warming in the twentieth century occurred in two periods, one in the early twentieth century from about the early 1900s to the 1940s, and one later in the century from, roughly, the late 1960s to the end of the century. The model’s response requires the combination of solar and anthropogenic forcing to approximate the early twentieth-century warming, while the radiative forcing from increasing greenhouse gases is dominant for the response in the late twentieth century, confirming previous studies. Of particular interest here is the model’s amplification of solar forcing when this acts in combination with anthropogenic forcing. This difference is traced to the fact that solar forcing is more spatially heterogeneous (i.e., acting most strongly in areas where sunlight reaches the surface) while greenhouse gas forcing is more spatially uniform. Consequently, solar forcing is subject to coupled regional feedbacks involving the combination of temperature gradients, circulation regimes, and clouds. The magnitude of these feedbacks depends on the climate’s base state. Over relatively cloud-free oceanic regions in the subtropics, the enhanced solar forcing produces greater evaporation. More moisture then converges into the precipitation convergence zones, intensifying the regional monsoon and

Managing Reliability in the 21st Century  

SciTech Connect

The rapid pace of change at Ike end of the 20th Century should continue unabated well into the 21st Century. The driver will be the marketplace imperative of "faster, better, cheaper." This imperative has already stimulated a revolution-in-engineering in design and manufacturing. In contrast, to date, reliability engineering has not undergone a similar level of change. It is critical that we implement a corresponding revolution-in-reliability-engineering as we enter the new millennium. If we are still using 20th Century reliability approaches in the 21st Century, then reliability issues will be the limiting factor in faster, better, and cheaper. At the heart of this reliability revolution will be a science-based approach to reliability engineering. Science-based reliability will enable building-in reliability, application-specific products, virtual qualification, and predictive maintenance. The purpose of this paper is to stimulate a dialogue on the future of reliability engineering. We will try to gaze into the crystal ball and predict some key issues that will drive reliability programs in the new millennium. In the 21st Century, we will demand more of our reliability programs. We will need the ability to make accurate reliability predictions that will enable optimizing cost, performance and time-to-market to meet the needs of every market segment. We will require that all of these new capabilities be in place prior to the stint of a product development cycle. The management of reliability programs will be driven by quantifiable metrics of value added to the organization business objectives.

Federal laboratories for the 21st century  

Science Conference Proceedings (OSTI)

Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

Utopian Body: Alternative Experiences of Embodiment in 20th Century Utopian Literature  

E-Print Network (OSTI)

Utopian literature has typically viewed the body as a pitfall on the path to social perfectibility, and utopian planners envision societies where the troublesome body is distanced as much as possible from utopia's guiding force-Reason. However, after two world wars, the failure of communism, and a century of corrupt "utopian" projects like Hitler's social engineering, dystopian societies justified on the grounds of "rational planning" fail to convince us, and the body has risen as the new locus for identity and agency, a point of stability in a dangerous and unstable environment. In this dissertation, I argue that utopian literature in the late twentieth century has identified the body as key to imagining new alternatives and re-connecting with an increasingly jeopardized sense of immediate, embodied experience. Protagonists in utopian literature looking to escape dehumanizing and bureaucratic worlds find their loophole in the sensual rush of adrenaline and instinct and the jarring rejuvenation of nerve and muscle, experiences which are much more immediately real and trustworthy than the tenuous dictates of institutions that tumble easily into absurdity and terror. Survival necessitates a raw and transformed identity that transgresses the tightly regimented boundaries of civilization and embraces the tumultuous chaos of the fringes and countercultures. Here, utopia thrives. I ground this study in theoretical and sociological texts which recognize the centrality of the body in society and the dynamic potentiality of utopian thinking, and then examine how these developments unfold in utopian literature since the mid twentieth century. The body as utopia surfaces in a variety of ways: as the longing for movement in Kurt Vonnegut's Player Piano; as the creation of alternative spaces defined by embodiment in Angela Carter's Heroes and Villains and Chuck Palahniuk's Fight Club; as the exuberant immersion in the modified body in Chuck Palahniuk's Rant; and as the search for perfection in a detached and corporate world in Margaret Atwood's Oryx and Crake. I conclude with an assessment of utopia in the twenty-first century, referring to Cormac McCarthy's The Road as a barometer of the grim state of utopian possibility as we head into the next century.

The Conservation of Seventeenth Century Archaeological Glass  

E-Print Network (OSTI)

The primary goal of the conservator is to stabilize and conserve artifacts with the best possible treatment available. Ideally, these treatments are noninvasive and reversible, and maintain the integrity of the object as a top priority. In this respect, it is the responsibility of the conservator to research other possible treatments when traditional methods prove to be insufficient to properly stabilize and conserve an object. Sometimes choosing to treat with a seemingly unorthodox method is the only chance for the objects survival. Though glass is considered one of the most stable archaeological materials, noninvasive, reversible treatments are not always possible given the level of deterioration glass objects undergo within the archaeological setting, specifically the underwater or waterlogged archaeological setting. This research is a consideration and investigation of the use of silicone polymers and silanes as consolidation materials for 17th-century glass recovered from aqueous environments. Working within the Conservation Research Laboratory and the Archaeological Preservation Research Laboratory at Texas A and M University, a newly developed polymer passivation technique utilizing materials acquired from the Dow Corning Corporation was applied to archaeological glass recovered from the 1686 shipwreck La Belle, excavated in Matagorda Bay off the coast of Texas by the Texas Historical Commission from 1996 to 1997. The successful application of a hydroxyl ended silicone polymer Q-1 3563, combined with a methyltrimethoxysilane intermediate crosslinker, Q-9 1315, at a 15% solution by weight and catalyzed with dibutyltin diacetate (DBTDA Fascat 4200) occurred in 1999. This project was the first large scale application of silicone polymers and silanes to 17th-century archaeological glass recovered from a marine site. Through this investigation we answered a number of questions regarding the use and application of the silicone technologies and confirmed that these materials are a viable resource for glass consolidation and conservation in terms of the suggested conservation guidelines of the IIC. The silicone technology was successfully applied to numerous types, forms, colors and degradation levels of glass. This included successful application to composite artifacts and the retreatment of objects unsuccessfully treated with a "traditional" method.

Foreign Travel Trip Report for LLNL travel with DOE FES funding,May 19th-30th, 2012  

Science Conference Proceedings (OSTI)

I attended the 20th biannual International Conference on Plasma Surface Interaction (PSI) in Fusion Devices in Aachen, Germany, hosted this year by the Forschungszentrum Julich (FZJ) research center. The PSI conference is one of the main international forums for the presentation and discussion of results on plasma surface interactions and edge plasma physics relevant to magnetic confinement fusion devices. I disseminated the recent results of FESP/LLNL tokamak research by presenting three posters on: (i) understanding reconnection and controlling edge localized modes (ELMs) using the BOUT++ code, (ii) simulation of resistive ballooning mode turbulence, and (iii) innovative design of Snowflake divertors. I learned of many new and recent results from international tokamak facilities and had the opportunity for discussion of these topics with other scientists at the poster sessions, conference lunches/receptions, etc. Some of the major highlights of the PSI conference topics were: (1) Review of the progress in using metallic tungsten and beryllium (ITER-like) walls at international tokamak facilities: JET (Culham, UK), TEXTOR (FZJ, Germany) and Alcator CMOD (MIT, USA). Results included: effect of small and large-area melting on plasma impurity content and recovery, expected reduction in retention of hydrogenic species, increased heat load during disruptions and need for mitigation with massive gas injection. (2) A review of ELM control in general (T. Evans, GA) and recent results of ELM control using n=2 external magnetic perturbations on ASDEX-Upgrade (MPI-Garching, Germany). (3) General agreement among the international tokamak database that, along the outer midplane of a low collisionality tokamak, the SOL power width in current experiments varies inversely with respect to plasma current (Ip), roughly as 1/Ip, with little dependence on other plasma parameters. This would imply roughly a factor of 1/4 of the width that was assumed for the design of the ITER tokamak. The first studies of the implications for ITER (A. Kukushkin, ITER) have shown a great reduction in operational parameter space that, at present, can only be lifted by increasing target plate heat flux limits. During my visit to the CRPP at the EPFL, I delivered an invited talk in order to disseminate new results of the recent publication [1] on using non-axisymmetric perturbations of the SOL to control the edge plasma. I was given a tour of both the TCV tokamak and the TORPEX simple magnetized plasma device/divertor simulator. TORPEX is an excellent laboratory for exploring the physics of simple magnetized plasmas that are relevant to the scrape-off layer of a tokamak. Properly designed experiments on TORPEX can potentially be used to test the theory of controlling the edge plasma using non-axisymmetric potentials and currents in the SOL developed by LLNL described in [1].

Directions for advanced use of nuclear power in century XXI  

SciTech Connect

Nuclear power can provide a significant contribution to electricity generation and meet other needs of the world and the US during the next century provided that certain directions are taken to achieve its public acceptance. These directions include formulation of projections of population, energy consumption, and energy resources over a responsible period of time. These projections will allow assessment of cumulative effects on the environment and on fixed resources. Use of fossil energy resources in a century of growing demand for energy must be considered in the context of long-term environmental damage and resource depletion. Although some question the validity of these consequences, they can be mitigated by use of advanced fast reactor technology. It must be demonstrated that nuclear power technology is safe, resistant to material diversion for weapon use, and economical. An unbiased examination of all the issues related to energy use, especially of electricity, is an essential direction to take.

Space power technology into the 21st century  

DOE Green Energy (OSTI)

This paper discusses the space power systems of the early 21st century. The focus is on those capabilities which are anticipated to evolve from today's state-of-the-art and the technology development programs presently in place or planned for the remainder of the century. The power system technologies considered include solar thermal, nuclear, radioisotope, photovoltaic, thermionic, thermoelectric, and dynamic conversion systems such as the Brayton and Stirling cycles. Energy storage technologies considered include nickel hydrogen biopolar batteries, advanced high energy rechargeable batteries, regenerative fuel cells, and advanced primary batteries. The present state-of-the-art of these space power and energy technologies is discussed along with their projections, trends and goals. A speculative future mission model is postulated which includes manned orbiting space stations, manned lunar bases, unmanned earth orbital and interplanetary spacecraft, manned interplanetary missions, military applications, and earth to space and space to space transportation systems. The various space power/energy system technologies anticipated to be operational by the early 21st century are matched to these missions.

21st Century jobs initiative - building the foundations for a 21st Century economy. Final main report  

SciTech Connect

The 21st Century Jobs Initiative has been launched in the context of new realities in Washington, D.C., rapid restructuring of the US economy and accelerating changes in the makeup of the East Tennessee economy driven by these and other external economic forces. Continuing downward pressure on Federal budgets for programs that support three key institutions in the region - DOE`s Oak Ridge complex, the Tennessee Valley Authority and research programs of the University of Tennessee - are especially threatening to the region. With a large part of its economy dependent on Federal spending, the area is at risk of troublesome impacts that could ripple out from the Oak Ridge and Knoxville home of these institutions throughout the entire 15-county {open_quotes}Resource Valley.{close_quotes} As these economic forces play out in the region`s economy, important questions arise. How will East Tennessee {open_quotes}earn its living{close_quotes} in the future if the Federal government role in the economy shrinks? What kind of new industries will be formed to replace those at risk due to Federal cutbacks and economic restructuring? Where will the jobs come from for the next generation of job seekers? These are among the questions driving the 21st Century Jobs Initiative, an action-oriented program designed and implemented by local leaders in response to the economic challenges facing East Tennessee. Fortunately, the region`s economy is strong today. Unemployment is at near record lows in most counties. Moreover, leaders are increasingly aware of the threats on the horizon and are already moving to action. And the impacts from the forces at work on the economy will probably come slowly, over the next decade or so. Based on economic research and input from local leaders knowledgeable about the economy, the 21st Century Jobs Initiative has set forth a strategic economic development plan for the region.

Anti-gravity: The key to 21st century physics  

Science Conference Proceedings (OSTI)

The masses coupling constants and cosmological parameters obtained using our discrete and combinatorial physics based on discrimination between bit-strings indicate that we can achieve the unification of quantum mechanics with relativity which had become the goal of twentieth century physics. To broaden our case we show that limitations on measurement of the position and velocity of an individual massive particle observed in a colliding beam scattering experiment imply real, rational commutation relations between position and velocity. Prior to this limit being pushed down to quantum effects, the lower bound is set by the available technology, but is otherwise scale invariant. Replacing force by force per unit mass and force per unit charge allows us to take over the Feynman-Dyson proof of the Maxwell Equations and extend it to weak gravity. The crossing symmetry of the individual scattering processes when one or more particles are replaced by anti-particles predicts both Coulomb attraction (for charged particles) and a Newtonian repulsion between any particle and its anti-particle. Previous quantum results remain intact, and predict the expected relativistic fine structure and spin dependencies. Experimental confirmation of this anti-gravity prediction would inaugurate the physics of the twenty-first century.

Transforming Epidemiology for 21st Century Medicine and Public Health  

Science Conference Proceedings (OSTI)

n 2012, the National Cancer Institute (NCI) engaged the scientific community to provide a vision for cancer epidemiology in the 21st century. Eight overarching thematic recommendations, with proposed corresponding actions for consideration by funding agencies, professional societies, and the research community emerged from the collective intellectual discourse. The themes are (i) extending the reach of epidemiology beyond discovery and etiologic research to include multilevel analysis, intervention evaluation, implementation, and outcomes research; (ii) transforming the practice of epidemiology by moving toward more access and sharing of protocols, data, metadata, and specimens to foster collaboration, to ensure reproducibility and replication, and accelerate translation; (iii) expanding cohort studies to collect exposure, clinical, and other information across the life course and examining multiple health-related endpoints; (iv) developing and validating reliable methods and technologies to quantify exposures and outcomes on a massive scale, and to assess concomitantly the role of multiple factors in complex diseases; (v) integrating big data science into the practice of epidemiology; (vi) expanding knowledge integration to drive research, policy, and practice; (vii) transforming training of 21st century epidemiologists to address interdisciplinary and translational research; and (viii) optimizing the use of resources and infrastructure for epidemiologic studies. These recommendations can transform cancer epidemiology and the field of epidemiology, in general, by enhancing transparency, interdisciplinary collaboration, and strategic applications of new technologies. They should lay a strong scientific foundation for accelerated translation of scientific discoveries into individual and population health benefits.

Daphne in the twentieth century: the grotesque in modern poetry  

E-Print Network (OSTI)

This dissertation seeks to expose the importance of the grotesque in the poetry and writings of Trans-Atlantic poets of the early twentieth century, particularly Ezra Pound, H.D., William Carlos Williams, Mina Loy, Marianne Moore and T.S. Eliot. Prior scholarship on the poets minimizes the effect of the grotesque in favor of the more objective elements found in such movements as Imagism. This text argues that these poets re-established the grotesque in their writing after World War I mainly through Hellenic myths, especially myths concerning the motif of the tree. The myths of Daphne and Apollo, Baucis and Philemon, and others use the tree motif as an example of complete metamorphosis into a new identity. This is an example of what Mikhail Bakhtin entitles grotesque realism, a type of grotesque not acknowledged in art since the French Revolution. Since the revolution, the grotesque involved an image trapped between two established forms of identity, or what Bakhtin refers to as the Romantic grotesque. This grotesque traps the image in stasis and does not provide a dynamic change of identity in the same way as grotesque realism. Therefore, these poets introduce the subversive act of change of identity in Western literature that had been absent for the most part for nearly a century. The modern poets pick up the use of the complete metamorphosis found in Hellenic myth in order to identify with a constantly changing urban environment that alienated its inhabitants. The modern city is a form of the grotesque in that it has transformed its environment from a natural state to a manmade state that is constantly in a state of transformation, itself. The modern poets use Hellenic myths and the tree motif to create an identity for themselves that would be as dynamic in transformation as the environment they inhabited.

Communicating 21st century statecraft: Evaluating the paradigm shift argument  

E-Print Network (OSTI)

This project examines how social media is being used by individuals within the State Department engaged in public diplomacy and how the use of these technologies may or may not represent a paradigm shift in diplomatic operation. Assessments of social media and government in popular culture argue a fundamental shift has taken place in government operations. Yet this argument calls for theoretical examination using communication theory and via examination of organizational praxis. Using Ammon's criterion for paradigm shift in communications technology and diplomacy, I evaluated State's current program of social media and public diplomacy called 21st Century Statecraft. I conducted a content analysis of organizational Twitter feeds and also interviewed actors within the organization working with public diplomacy and social media. I also examined historical accounts of State's Voice of America radio program, and compared current organizational uses of social media with the appropriation of radio in the second half of the 20th century. The results suggest that paradigm shift has not yet occurred despite the uses of the new technologies. In many cases, social media is being used akin to technologies from previous paradigms due in part to the constraints of organizational structures. Twitter platforms were used as spaces to push information and policy to the masses, similar to the ways in which radio was used after World War II and throughout the Cold War. Organizational actors characterized social media as a tool to accomplish public diplomacy, not as the change agent those outside of the organization have argued it to be. They described organizational challenges of incorporating social media including questions of voice, information control, and doing 'in-reach' inside the organization. Finally, they described aspects of the interaction that took place as an opportunity to create dialogue amongst interested citizens around the world and to come into face-to-face contact with individuals outside the embassy. Although anomalous practices have begun to emerge as a result of new media's use in the State Department, we have not reached what Kuhn would term a 'critical mass,' necessitating a shift in worldview and practice.

ALS Scientists Patent Technique To ALS Scientists Patent Technique To Dramatically Advance Grating-Based Spectroscopy ALS Scientists Patent Technique To Dramatically Advance Grating-Based Spectroscopy Print Tuesday, 29 January 2013 16:28 Gratings - optical elements used to separate light in spectroscopy applications - have been in use since the early 19th century. Developments in the late 19th century led to the manufacture of gratings by highly precise ruling with a diamond onto a metallic surface. Many gratings are still produced today using the same technique. Holographic methods and ion etching are also used, but all of these techniques result in gratings that contain significant imperfections, which limits resolution. Watch a video about this topic... However, a new type of ultra-high diffraction grating recently patented by members of the ALS Experimental Systems Group (ESG), working with colleagues from Berkeley Lab's Center for X-ray Optics, stands to revolutionize the resolution capabilities of soft x-ray spectroscopy. The key to the new technique is the production of a near atomically perfect substrate, using the anisotropic etching of silicon.

Late Light Curves of Normally-Luminous Type Ia Supernovae  

E-Print Network (OSTI)

The use of Type Ia supernovae as cosmological tools has reinforced the need to better understand these objects and their light curves. The light curves of Type Ia supernovae are powered by the nuclear decay of $^{56}Ni \\to ^{56}Co \\to ^{56}Fe$. The late time light curves can provide insight into the behavior of the decay products and their effect of the shape of the curves. We present the optical light curves of six "normal" Type Ia supernovae, obtained at late times with template image subtraction, and the fits of these light curves to supernova energy deposition models.

Computing, information, and communications: Technologies for the 21. Century  

Science Conference Proceedings (OSTI)

To meet the challenges of a radically new and technologically demanding century, the Federal Computing, Information, and Communications (CIC) programs are investing in long-term research and development (R and D) to advance computing, information, and communications in the United States. CIC R and D programs help Federal departments and agencies to fulfill their evolving missions, assure the long-term national security, better understand and manage the physical environment, improve health care, help improve the teaching of children, provide tools for lifelong training and distance learning to the workforce, and sustain critical US economic competitiveness. One of the nine committees of the National Science and Technology Council (NSTC), the Committee on Computing, Information, and Communications (CCIC)--through its CIC R and D Subcommittee--coordinates R and D programs conducted by twelve Federal departments and agencies in cooperation with US academia and industry. These R and D programs are organized into five Program Component Areas: (1) HECC--High End Computing and Computation; (2) LSN--Large Scale Networking, including the Next Generation Internet Initiative; (3) HCS--High Confidence Systems; (4) HuCS--Human Centered Systems; and (5) ETHR--Education, Training, and Human Resources. A brief synopsis of FY 1997 accomplishments and FY 1998 goals by PCA is presented. This report, which supplements the President`s Fiscal Year 1998 Budget, describes the interagency CIC programs.

Infrastructure: A technology battlefield in the 21st century  

Science Conference Proceedings (OSTI)

A major part of technological advancement has involved the development of complex infrastructure systems, including electric power generation, transmission, and distribution networks; oil and gas pipeline systems; highway and rail networks; and telecommunication networks. Dependence on these infrastructure systems renders them attractive targets for conflict in the twenty-first century. Hostile governments, domestic and international terrorists, criminals, and mentally distressed individuals will inevitably find some part of the infrastructure an easy target for theft, for making political statements, for disruption of strategic activities, or for making a nuisance. The current situation regarding the vulnerability of the infrastructure can be summarized in three major points: (1) our dependence on technology has made our infrastructure more important and vital to our everyday lives, this in turn, makes us much more vulnerable to disruption in any infrastructure system; (2) technologies available for attacking infrastructure systems have changed substantially and have become much easier to obtain and use, easy accessibility to information on how to disrupt or destroy various infrastructure components means that almost anyone can be involved in this destructive process; (3) technologies for defending infrastructure systems and preventing damage have not kept pace with the capability for destroying such systems. A brief review of these points will illustrate the significance of infrastructure and the growing dangers to its various elements.

Data Analysis in the Twenty-First Century  

SciTech Connect

The 21st Century is characterized by complex multidisciplinary problems accompanied by massive datasets. 'We are drowning in data, but starving for knowledge', as the volumes of many commercial, industrial and scientific datasets have exceeded the terabyte range and are approaching petabytes and beyond. Statistical methodology has long been employed to find useful and usable information in data. More recently, data mining has harnessed the power of computer technology to find useful and usable patterns in such massive datasets. Although several data mining journals have joined the established statistical journals, no single journal provides an integrated treatment of statistical analysis methodology and data mining technology, particularly when applied to the solution of practical problems. This absence and the needs expressed above motivated the inauguration of John Wiley's new Journal on Statistical Analysis and Data Mining. The goals of this interdisciplinary journal are to encourage collaborations across disciplines, communication of data mining and statistical techniques to both novices and experts involved in the analysis of data from practical problems, and a principled and productive evaluation of analyses and solutions. The journal specifically encourages submission of works that have statistical rigor in the analysis of data, incorporate the most appropriate algorithms from data mining, and address the needs of applications. Applying data mining algorithms to practical problems is not sufficient, because we need to ensure that the results have a sound statistical basis, lest any decision based on these results lead to a catastrophe. Even data mining algorithms founded on sound statistical analysis are not sufficient, if they cannot solve a practical problem. Finally, employing a statistical analysis on a practical problem is not sufficient, unless it scales up to massive datasets. Statistical analysis and data mining are actually two sides of the sword that is sorely needed to conquer data overload in practical problems.

Wholesale gasoline prices account for most of the modest recovery. This issue features latest trends affecting margins in the two main US refining centers, and offers a new comparison of the two. The issue also presents the following: (1) the ED Refining Netback Data Series for the US Gulf and West Coasts, Rotterdam and Singapore as of August 9, 1991; and (2) the ED Fuel Price/Tax Series for countries of the Western Hemisphere, August 1991 Edition. 7 figs., 5 tabs.

Century-Midas steps slowly into the RV (recreational vehicles) LPG conversion market  

SciTech Connect

Midas International will obtain LPG carburetion equipment from Century for installation in up to 20,000 RV. The market for gasoline-powered RV has been depressed since the surge in gasoline prices, and the installation of Century's equipment represents an attempt to attract customers by reducing RV operating costs. According to J. Kincaid (Midas Inst.), propane, besides being cheaper than gasoline, is also cheaper than diesel fuel, despite the better mileage obtained with diesel fuel, because the use of diesel fuel requires the installation of a diesel engine, which is far more expensive than installation of LPG carburetion. Although most of the LPG carburetion manufacturers, with a backlog of orders, did not evince interest in Midas' search for conversion equipment for RV, Century responded, at least partly because Midas also manufactures fleet delivery trucks, which represent a potentially much larger market for LPG conversion and use.

Magnetized dark energy and the late time acceleration  

E-Print Network (OSTI)

In the present work we have searched the existence of the late time acceleration of the Universe. The matter source that is responsible for the late time acceleration of the Universe consists of cosmic fluid with the equation of state parameter $\\omega =\\frac{p}{\\rho}$ and uniform magnetic field of energy density $\\rho_{B}$. The study is done here under the framework of spatially homogeneous and anisotropic locally rotationally symmetric (LRS) Bianchi-I cosmological model in the presence of magnetized dark energy. To get the deterministic model of the Universe, we assume that the shear scalar $(\\sigma)$ in the model is proportional to expansion scalar $(\\theta)$. This condition leads to $A=B^{n}$, where $A$ and $B$ are metric functions and $n$ is a positive constant giving the proportionality condition between shear and expansion scalar. It has been found that the isotropic distribution of magnetized dark energy leads to the present accelerated expansion of the Universe and the derived model is in good agreement with the recent astrophysical observations. The physical behavior of the Universe has been discussed in details.

GEOPHYSICAL INVESTIGATIONS OF THE ARCHAEOLOGICAL RESOURCES AT THE POWELL STAGE STATION  

SciTech Connect

Within the boundaries of the Idaho National Laboratory, an ongoing archaeological investigation of a late 19th century stage station was expanded with the use of Electro-Magnetic and Magnetic geophysical surveying. The station known as the Powell Stage Station was a primary transportation hub on the Snake River Plain, bridging the gap between railroad supply depots in Blackfoot, Idaho and booming mining camps throughout Central Idaho. Initial investigations have shown a strong magnetic signature from a buried road and previously unknown features that were not detected by visual surface surveys. Data gained from this project aids in federally directed cultural resource and land management and use requirements and has contributed additional information for archeological interpretation and cultural resource preservation.

Energy System Expectations for Nuclear in the 21. Century: A Plausible Range  

SciTech Connect

This paper outlines a range of scenarios describing what the world's energy system might look like in the middle of the century, and what nuclear energy's most profitable role might be. The starting point is the 40 non-greenhouse-gas-mitigation scenarios in the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change (IPCC, 2000). Given their international authorship and comprehensive review by governments and scientific experts, the SRES scenarios are the state of the art in long-term energy scenarios. However, they do not present the underlying energy system structures in enough detail for specific energy technology and infrastructure analyses. This paper therefore describes initial steps within INPRO (The International Project on Innovative Nuclear Reactors and Fuel Cycles of the International Atomic Energy Agency) to translate the SRES results into a range of possible nuclear energy technology requirements for mid-century. The paper summarizes the four SRES scenarios that will be used in INPRO and the reasons for their selection. It provides illustrative examples of the sort of additional detail that is being developed about the overall energy system implied by each scenario, and about specific scenario features particularly relevant to nuclear energy. As recommended in SRES, the selected scenarios cover all four SRES 'story-line families'. The energy system translations being developed in INPRO are intended to indicate how energy services may be provided in mid-century and to delineate likely technology and infrastructure implications. They will indicate answers to questions like the following. The list is illustrative, not comprehensive. - What kind of nuclear power plants will best fit the mid-century energy system? - What energy forms and other products and services provided by nuclear reactors will best fit the mid-century energy system? - What would be their market shares? - How difficult will it be to site new nuclear facilities? - Which are nuclear energy's biggest competitors? - Which non-nuclear technologies can nuclear power complement? - What is the range of potential demand growth for new capacity? - How is demand growth distributed geographically around the world? Different scenarios imply different answers, which are then the starting point for estimating what future reactor users might require of reactor and fuel cycle designs around mid-century. These user requirements - in terms of economics, safety, proliferation resistance, waste, and environmental impacts - are intended to help establish key directions in which to encourage innovation. They are intended as a useful input to managers designing R and D strategies targeted on the anticipated energy system needs, and other relevant needs, of mid-century. (authors)

MEMOIRS OF A LEAK: Infiltrating Research for a Quarter of a Century MEMOIRS OF A LEAK: Infiltrating Research for a Quarter of a Century Speaker(s): Max Sherman Date: November 16, 2000 - 12:00pm Location: Bldg. 90 Seminar Host/Point of Contact: David Faulkner Infiltration is the (usually uncontrolled) flow of air through leaks in the building envelope, driven by natural and mechanical pressures. Before the oil crises, there was not a lot of interest in infiltration. For houses and other envelope-dominated buildings, however, infiltration typically accounted for all of their ventilation needs and 1/3-1/2 of their space-conditioning load. Starting in the mid-70s there was a realization that this important problem was not well understood, but represented an important energy-saving opportunity. Research institutions around the world

Climate Change Policies for the XXIst Century: Mechanisms, Predictions and Recommendations  

E-Print Network (OSTI)

Recent experimental works demonstrated that the Anthropogenic Global Warming (AGW) hypothesis, embodied in a series of Intergovernmental Panel on Climate Change (IPCC) global climate models, is erroneous. These works prove that atmospheric carbon dioxide contributes only very moderately to the observed warming, and that there is no climatic catastrophe in the making, independent on whether or not carbon dioxide emissions will be reduced. In view of these developments, we discuss climate predictions for the XXIst century. Based on the solar activity tendencies, a new Little Ice Age is predicted by the middle of this century, with significantly lower global temperatures. We also show that IPCC climate models can't produce any information regarding future climate, due to essential physical phenomena lacking in those, and that the current budget deficit in many EU countries is mainly caused by the policies promoting renewable energies and other AGW-motivated measures. In absence of any predictable adverse climate...

Late biological effects from internal and external exposure  

Science Conference Proceedings (OSTI)

Information on late biological effects of radiation was obtained from the long-term medical followup of a small population of Marshallese accidentally exposed to radioactive fallout from a thermonuclear test in 1954. Endocrine data are compatible with a sequence of nonstochastic radiation effects. The ingestion of radioisotopes of iodine produced clinical thyroid hypofunction in children, biochemical evidence of thyroid dysfunction in some adults, thyroid adenomatous module formation, and, as a possible indirect effect of thyroid damage, at least two cases of pituitary adenoma. In contrast, the only evidence of a stochastic effect has been a real increase in thyroid cancers among the more highly exposed people of Rongelap, none of whom have evidence of residual disease. While three nonthyroidal cancers which are known to be inducible in humans by external irradiation have been documented in the exposed population, three similar cancers have occurred in an unexposed comparison population of Marshallese. Nonstochastic effects of radiation exposure may be common but subtle. In the Marshallese experience the morbidity of delayed nonstochastic effects far exceeds that of the stochastic. 20 refs., 5 figs., 1 tab.

The engineering giants of the late 19th and early 20th centuries set humanity on a journey from which there is no turning back. This year, we celebrated the 100th anniversary of the American Society of Heating, refrigerating, and Air-Conditioning Engineers, Inc. (ASHRAE`s) founding and a century of advancing heating, ventilating, air-conditioning and refrigerating (HVAC&R) technology. We stood on the shoulders of these engineering giants, and we viewed the Society`s achievements in a perfect perspective. My theme for this year - Building on the Shoulders of Giants - recognizes their work and describes our journey forward into ASHRAE`s second century. Through our Centennial Celebration, we involved members at all levels of the Society, from our oldest members to students, from the Executive Committee to the Board of Directors to the regions and to the local chapters and individual members. We also involved our associate societies and other related organizations. This publication describes the activities of ASHRAE for 1995.

Steel industry of the future: Meeting the material challenges of the 21. century  

SciTech Connect

For over a century, the US steel industry has led the global market with advances in technology, product development, and marketing. Industry leaders recognize both the opportunities and challenges they face as they head into the 21st century, and that cooperative R and D is key to their success. In a unique partnership, steel industry leaders have teamed with the US Department of Energy`s Office of Industrial Technologies (OIT) to focus on innovative technologies that will help to strengthen the competitive position of the US steel industry and, at the same time, further important national goals. This industry-led partnership, the Steel Industry of the Future, promotes technologies that optimize the use of energy and materials in operation and reduce wastes and energy-related emissions. Led by the American Iron and Steel Institute (AISI) and the Steel Manufacturers Association (SMA), industry leaders began by developing a unified vision for the next 20 years: to provide high-quality, value-added products to a wide array of customers in an environmentally friendly, cost-effective manner, while leading the world in innovation and technology. Continued global leadership in materials markets will require the combined resources of industry, universities, and government laboratories. The steel industry vision provided a framework for the next step in the Industries of the Future process, the development of a technology roadmap designed to facilitate collaborative R and D on advanced processes and technologies for the steel industry.

Climate Change Policies for the XXIst Century: Mechanisms, Predictions and Recommendations  

E-Print Network (OSTI)

Recent experimental works demonstrated that the Anthropogenic Global Warming (AGW) hypothesis, embodied in a series of Intergovernmental Panel on Climate Change (IPCC) global climate models, is erroneous. These works prove that atmospheric carbon dioxide contributes only very moderately to the observed warming, and that there is no climatic catastrophe in the making, independent on whether or not carbon dioxide emissions will be reduced. In view of these developments, we discuss climate predictions for the XXIst century. Based on the solar activity tendencies, a new Little Ice Age is predicted by the middle of this century, with significantly lower global temperatures. We also show that IPCC climate models can't produce any information regarding future climate, due to essential physical phenomena lacking in those, and that the current budget deficit in many EU countries is mainly caused by the policies promoting renewable energies and other AGW-motivated measures. In absence of any predictable adverse climate consequences of carbon dioxide emissions, and with no predictable shortage of fossil fuels, we argue for recalling of all policies aimed at reducing carbon dioxide emissions and usage of expensive renewable energy sources. The concepts of carbon credits, green energy and green fuels should be abandoned in favor of productive, economically viable and morally acceptable solutions.

The distribution of an illustrated timeline wall chart and teacher's guide of 20th century physics  

SciTech Connect

The American Physical Society's part of its centennial celebration in March of 1999 decided to develop a timeline wall chart on the history of 20th century physics. This resulted in eleven consecutive posters, which when mounted side by side, create a 23-foot mural. The timeline exhibits and describes the millstones of physics in images and words. The timeline functions as a chronology, a work of art, a permanent open textbook, and a gigantic photo album covering a hundred years in the life of the community of physicists and the existence of the American Physical Society. Each of the eleven posters begins with a brief essay that places a major scientific achievement of the decade in its historical context. Large portraits of the essays' subjects include youthful photographs of Marie Curie, Albert Einstein, and Richard Feynman among others, to help put a face on science. Below the essays, a total of over 130 individual discoveries and inventions, explained in dated text boxes with accompanying images, form the backbone of the timeline. For ease of comprehension, this wealth of material is organized into five color-coded story lines the stretch horizontally across the hundred years of the 20th century. The five story lines are: Cosmic Scale, relate the story of astrophysics and cosmology; Human Scale, refers to the physics of the more familiar distances from the global to the microscopic; Atomic Scale, focuses on the submicroscopic world of atoms, nuclei and quarks; Living World, chronicles the interaction of physics with biology and medicine; Technology, traces the applications of physic to everyday living. Woven into the bottom border of the timeline are period images of significant works of art, architecture, and technological artifacts such as telephones, automobiles, aircraft, computers, and appliances. The last poster, covering the years since 1995, differs from the others. Its essay concerns the prospect for physics into the next century, and is illustrated with pictures of promising award winning high school students who, it is hoped, will be the leading researchers of physics in the decades ahead. Appropriately the last entries in the timeline are not achievements but open questions to be answered in the future.

New courses for the Colorado River: Major issues for the next century  

Science Conference Proceedings (OSTI)

The Colorado River is the sole dependable water supply for a quarter million square miles in seven western states and Mexico. Its waters are truly a scarce resource in a dry land, and consequently the Colorado is the most intensively managed river of its size in the world. Yet as Governor Bruce Babbitt notes here, the basic accord governing the river-the Colorado River Compact of 1922-''provides little guidance on the major issues of the next century, namely equitable resolution of Indian claims and water quality.'' These issues and others are addressed fully by more than fifteen leading scholars who command a thorough working knowledge of the history of the river and the controversies that continue to surround its uses. This book addresses the issues surrounding the uses of the Colorado River since the 1922 compact.

Challenges in the Twentieth Century and Beyond: Computer codes and data  

SciTech Connect

The second half of the twentieth century has seen major changes in computer architecture. In the early fifties to the early seventies, the word ``computes`` demanded reverence, respect and even fear. Computers, then, were almost ``untouchable``. Today, computers have become the mainstreams of communication on the rapidly expanding communication highways. They have become necessities of life. With the computers came the establishment of information centers -- tasked with the dissemination of newly developed computer codes and generated data. The Radiation Shielding Information Center (RSIC) was founded in 1962 as a valuable resource for programs and cross section data concerned with the effects of radiation. Through the years, RSIC has collected computer codes developed for the early machines (IBM 360, DEC PDP-10, CDC 660, UNIVAC 1100), to the more modern and powerful desktops (Pentium based Personal Computers, UNIX workstations like the IBM RISC 6000, DEC Alpha, SUN) and supercomputers (Cray XMP, Cray YMP, Cray C90, IBM SP2).

Energy Technologies for the 21st Century-The Roles of Renewable Energy  

DOE Green Energy (OSTI)

Renewable energy sources, originating for the most part from the sun's radiant energy, are ubiquitous, long-lived, essentially free of carbon emissions, and have the potential to contribute significantly to mounting energy needs of the globe. In terms of percentage increase in installed capacity, renewable energy collectively is the fastest growing energy source. Even assuming that the developing world raises its standard of living considerably, the technical potential of renewable energies is more than enough to meet annual global needs several times over a century from now. Realizing even some of this potential involves overcoming obstacles in generation costs, proximity to markets, and in many cases intermittency, as well as others. From the perspective of work on a wide range of energy technologies by both the World Energy Council and the Intergovernmental Panel on Climate Change, the potential, timing, and investment costs for renewable energy technologies in the 21st century have become clearer. The marketplace, based on cost and performance, will determine which technologies are commercialized along with government policies that at a minimum do not hinder their introduction, and--at a maximum--may encourage more rapid and successful introduction. A wide range of possible scenarios (34) based on factors that include energy availability, demographics, economic development, competition, environmental constraints, and most importantly technical learning, place some constraints on the range of possible energy requirements. Most scenarios indicate that renewable energy in total is likely to be as much as half the world's supply in 100 years, but most of that growth is expected in the period 50 to 100 years from now--if critical advancements and investments are made over the next 50 years.

20th Century Reanalysis Project Ensemble Gateway: 56 Estimates of World Temperature, Pressure, Humidity, and Wind, 1871-2010  

DOE Data Explorer (OSTI)

This site provides data from the 20th Century Reanalysis Project, offering temperature, pressure, humidity, and wind predictions in 200 km sections all around the earth from 1871 to 2010, every 6 hours, based on historical data. The ensemble mean and standard deviation for each value were calculated over a set of 56 simulations. Data for each of the 56 ensemble members are included here. The dataset consists of files in netCDF 4 format that are available for download from the National Energy Research. The goal of the 20th Century Reanalysis Project is to use a Kalman filter-based technique to produce a global trophospheric circulation dataset at four-times-daily resolution back to 1871. The only dataset available for the early 20th century consists of error-ridden hand-drawn analyses of the mean sea level pressure field over the Northern Hemisphere. Modern data assimilation systems have the potential to improve upon these maps, but prior to 1948, few digitized upper-air sounding observations are available for such a reanalysis. The global tropospheric circulation dataset will provide an important validation check on the climate models used to make 21st century climate projections....[copied from http://portal.nersc.gov/project/20C_Reanalysis/

Late Paleozoic-early Mesozoic history of the Pacific margin along Antarctica  

SciTech Connect

The late Paleozoic-early Mesozoic Pacific margin of Gondwanaland from eastern Australia to Patagonia was characterized by a series of back-arc and foreland basins associated with subduction and volcanism. The Transantarctic basin including the present Transantarctic Mountains and Tasmania evolved from a middle Paleozoic passive continental margin to an Early Permian back-arc basin and a Late Permian-Triassic foreland basin. The earliest evidence of a volcanic arc and subduction is the appearance of abundant volcanic detritus at the base of the Early Permian postglacial marine shale-and-sandstone sequence in the Ellsworth Mountains. Volcaniclastic forearc sediments of Permian( ) to Triassic age are known from the Antarctic Peninsula. The introduction of abundant volcanic detritus to the East Antarctic craton and a 180{degree} paleocurrent reversal in the Late Permian in the Beardmore Glacier area is the earliest evidence of folding along the Antarctic-Pacific margin. By the Early Triassic, folding involved Late Permian sequences in the Ellsworth and Transantarctic (Pensacola) mountains. Thick Upper Permian and Triassic braided-stream deposits of mixed volcanic and cratonic provenance accumulated in this foreland basin. Subsidence ended in the Early Jurassic with uplift and diabase intrusion associated with the breakup of Gondwanaland.

Behavior of Late Quaternary and historical faults in the western Basin and Range province  

Science Conference Proceedings (OSTI)

Quaternary stratigraphic relations and exploratory trenching in zones of historical surface faulting in the western Basin and Range Province suggest that faults with historical surface ruptures have similar, and in some cases lower, long-term (late Quaternary) and short-term (Holocene) slip rates than other adjacent and regional non-historical Quaternary faults. In the 1954 Dixie Valley earthquake (M6.8) zone, the range-front and piedmont faults collectively record a late Quaternary (200 ka) slip rate on the order of 0.2 mm/yr and a Holocene (7--12 ka) slip rate of 0.5--0.8 mm/yr. The principal segment of the 1932 Cedar Mountain earthquake (M7.2) zone has an estimated latest Quaternary (25--35 ka) slip rate of 0.2--0.7 mm/yr and a Holocene (6--13 ka) slip rate of 0.3--0.7 mm/yr. The 1954 Rainbow Mountain earthquakes (M6.6 and M6.8) and 1954 Fairview Peak earthquake (M7.1) zones have late Quaternary slip rates that are lower (=] 1 mm/yr. Based on a comparison of Holocene and late Quaternary rates, many, but not all, historical and non-historical zones show evidence of temporal clustering.

Influence of 21st century atmospheric and sea surface temperature forcing on West African climate  

SciTech Connect

he persistence of extended drought events throughout West Africa during the 20th century has motivated a substantial effort to understand the mechanisms driving African climate variability, as well as the possible response to elevated greenhouse gas (GHG) forcing. We use an ensemble of global climate model experiments to examine the relative roles of future direct atmospheric radiative forcing and SST forcing in shaping potential future changes in boreal summer precipitation over West Africa. We find that projected increases in precipitation throughout the Western Sahel result primarily from direct atmospheric radiative forcing. The changes in atmospheric forcing generate a slight northward displacement and weakening of the African easterly jet (AEJ), a strengthening of westward monsoon flow onto West Africa and an intensification of the tropical easterly jet (TEJ). Alternatively, we find that the projected decreases in precipitation over much of the Guinea Coast region are caused by SST changes that are induced by the atmospheric radiative forcing. The changes in SSTs generate a weakening of the monsoon westerlies and the TEJ, as well as a decrease in low-level convergence and resultant rising air throughout the mid levels of the troposphere. Our experiments suggest a potential shift in the regional moisture balance of West Africa should global radiative forcing continue to increase, highlighting the importance of climate system feedbacks in shaping the response of regional-scale climate to global-scale changes in radiative forcing.

Intensity, duration, and frequency of precipitation extremes under 21st-century warming scenarios  

Science Conference Proceedings (OSTI)

Recent research on the projection of precipitation extremes has either focused on conceptual physical mechanisms that generate heavy precipitation or rigorous statistical methods that extrapolate tail behavior. However, informing both climate prediction and impact assessment requires concurrent physically and statistically oriented analysis. A combined examination of climate model simulations and observation-based reanalysis data sets suggests more intense and frequent precipitation extremes under 21st-century warming scenarios. Utilization of statistical extreme value theory and resampling-based uncertainty quantification combined with consideration of the Clausius-Clapeyron relationship reveals consistently intensifying trends for precipitation extremes at a global-average scale. However, regional and decadal analyses reveal specific discrepancies in the physical mechanisms governing precipitation extremes, as well as their statistical trends, especially in the tropics. The intensifying trend of precipitation extremes has quantifiable impacts on intensity-duration-frequency curves, which in turn have direct implications for hydraulic engineering design and water-resources management. The larger uncertainties at regional and decadal scales suggest the need for caution during regional-scale adaptation or preparedness decisions. Future research needs to explore the possibility of uncertainty reduction through higher resolution global climate models, statistical or dynamical downscaling, as well as improved understanding of precipitation extremes processes.

SOLAR CYCLE PROPAGATION, MEMORY, AND PREDICTION: INSIGHTS FROM A CENTURY OF MAGNETIC PROXIES  

SciTech Connect

The solar cycle and its associated magnetic activity are the main drivers behind changes in the interplanetary environment and Earth's upper atmosphere (commonly referred to as space weather). These changes have a direct impact on the lifetime of space-based assets and can create hazards to astronauts in space. In recent years there has been an effort to develop accurate solar cycle predictions (with aims at predicting the long-term evolution of space weather), leading to nearly a hundred widely spread predictions for the amplitude of solar cycle 24. A major contributor to the disagreement is the lack of direct long-term databases covering different components of the solar magnetic field (toroidal versus poloidal). Here, we use sunspot area and polar faculae measurements spanning a full century (as our toroidal and poloidal field proxies) to study solar cycle propagation, memory, and prediction. Our results substantiate predictions based on the polar magnetic fields, whereas we find sunspot area to be uncorrelated with cycle amplitude unless multiplied by area-weighted average tilt. This suggests that the joint assimilation of tilt and sunspot area is a better choice (with aims to cycle prediction) than sunspot area alone, and adds to the evidence in favor of active region emergence and decay as the main mechanism of poloidal field generation (i.e., the Babcock-Leighton mechanism). Finally, by looking at the correlation between our poloidal and toroidal proxies across multiple cycles, we find solar cycle memory to be limited to only one cycle.

Bahamian ship graffiti  

E-Print Network (OSTI)

The Bahamian archipelago covers over 5,000 square miles of the Atlantic Ocean at the northwestern edge of the Caribbean Sea. In the Age of Sail, from the late 15th to early 20th centuries, these islands were on major sailing routes between the Caribbean, Central America, and Europe. Bahamians developed life-ways using their islands? location to their advantage. Archaeological evidence of the significance of shipping activity is quite lacking. This research aimed to help fill the void by documenting examples of ship graffiti throughout the Bahamas. Examples of ship graffiti were documented with photographs and tracings. The Bahamian examples all date to the 19th and 20th centuries, 100 years later than other examples from the Caribbean and North America. They are also unique in being incised into the stone surfaces of building walls, caves, stones on a hillside, even on a slate fragment. It is possible that ship graffiti were also engraved on wooden surfaces but these have not survived in the archaeological record. Images depict locally-built vessels such as sloops and schooners as well as larger, ocean-going vessels. Ship graffiti are at sites associated mainly with people of African heritage, another possible social grouping being persons of lower economic status. Graffiti details consistently indicate that the artists were familiar with ship construction and rigging. This analysis of ship graffiti gives some understanding of the significance of ships and shipping in the Bahamian economy.

"To make their owne termes": servant rebelliousness and the transitionto slavery in seventeenth-century Barbados and Virginia  

E-Print Network (OSTI)

Throughout the seventeenth century the English colonies of Barbados and Virginia relied upon the institution of indentured servitude to meet their labor needs. By the end of the seventeenth century, however, both colonies had come to rely upon African slavery as the primary source of laborers. Multiple factors prompted this change, including economic and demographic changes as well as social developments in each colony. The adoption of slave labor occurred, however, in the context of servant rebellions, a factor that has not been explored in the study of developing slave societies. Multiple rebellions on the island of Barbados and throughout the Virginia countryside helped create a context in which planters perceived servants to be more difficult to control than slaves. With that mindset, plantation owners turned to African slavery to meet their labor demands, benefit them economically, and alleviate real or perceived social pressures caused by servant rebellion.

Climate mitigation’s impact on global and regional electric power sector water use in the 21st Century  

SciTech Connect

Over the course of this coming century, global electricity use is expected to grow at least five fold and if stringent greenhouse gas emissions controls are in place the growth could be more than seven fold from current levels. Given that the electric power sector represents the second largest anthropogenic use of water and given growing concerns about the nature and extent of future water scarcity driven by population growth and a changing climate, significant concern has been expressed about the electricity sector’s use of water going forward. In this paper, the authors demonstrate that an often overlooked but absolutely critical issue that needs to be taken into account in discussions about the sustainability of the electric sector’s water use going forward is the tremendous turn over in electricity capital stock that will occur over the course of this century; i.e., in the scenarios examined here more than 80% of global electricity production in the year 2050 is from facilities that have not yet been built. The authors show that because of the large scale changes in the global electricity system, the water withdrawal intensity of electricity production is likely to drop precipitously with the result being relatively constant water withdrawals over the course of the century even in the face of the large growth in electricity usage. The ability to cost effectively reduce the water intensity of power plants with carbon dioxide capture and storage systems in particular is key to constraining overall global water use.

CLARREO shortwave observing system simulation experiments of the twenty-first century: Simulator design and implementation  

Science Conference Proceedings (OSTI)

Projected changes in the Earth system will likely be manifested in changes in reflected solar radiation. This paper introduces an operational Observational System Simulation Experiment (OSSE) to calculate the signals of future climate forcings and feedbacks in top-of-atmosphere reflectance spectra. The OSSE combines simulations from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report for the NCAR Community Climate System Model (CCSM) with the MODTRAN radiative transfer code to calculate reflectance spectra for simulations of current and future climatic conditions over the 21st century. The OSSE produces narrowband reflectances and broadband fluxes, the latter of which have been extensively validated against archived CCSM results. The shortwave reflectance spectra contain atmospheric features including signals from water vapor, liquid and ice clouds, and aerosols. The spectra are also strongly influenced by the surface bidirectional reflectance properties of predicted snow and sea ice and the climatological seasonal cycles of vegetation. By comparing and contrasting simulated reflectance spectra based on emissions scenarios with increasing projected and fixed present-day greenhouse gas and aerosol concentrations, we find that prescribed forcings from increases in anthropogenic sulfate and carbonaceous aerosols are detectable and are spatially confined to lower latitudes. Also, changes in the intertropical convergence zone and poleward shifts in the subsidence zones and the storm tracks are all detectable along with large changes in snow cover and sea ice fraction. These findings suggest that the proposed NASA Climate Absolute Radiance and Refractivity Observatory (CLARREO) mission to measure shortwave reflectance spectra may help elucidate climate forcings, responses, and feedbacks.

US energy for the rest of the century. [From 1980 Mineral Economics Symposium  

SciTech Connect

This paper summarizes the basic quantitative results of recent US Commerce Department forecasting efforts in the energy area. This work has been published in three volumes by National Technical Information Service. It covers the entire spectrum of US energy requirements and focuses on the use of energy for operational purposes. The tables provide data on fuel consumption by types and Btu content both for 1979 and as projected for the year 2000. Three main points are highlighted in the tables: 1. The US energy problem, at least from now to the end of the century, is basically a petroleum problem. Liquid-fuel usage in the transprtation sector will suffer the greatest strain in the years ahead. 2. The automobile will have to become more fuel-efficient to meet the limits that will exist on petroleum supply. To meet expected constraints, a doubling of current mileage standards is necessary and 10% of automobiles may have to run on electricity and 10% on gasohol. 3. The continuing shift to electricity projected in the forecast will necessitate large conversion losses in electricity production from fossil fuels. When such losses are excluded, however, the forecast indicates that US net usable energy on a per capita basis by the year 2000 will actually be less than today and will continue to decline. Two other points deserve to be noted: (1) US end users of energy currently spend $316 billion annually; this includes direct taxes; and (2) almost 50% of our energy is used to produce steam. 3 references, 8 tables.

Apprentices in Trouble: Some Problems in the Training of Surgeons and Apothecaries in Seventeenth Century London  

E-Print Network (OSTI)

Mayor's Court interrogatories and depositions in six disputes between apprentices and their surgeon and apothecary masters in London in 1654-1684 are reviewed. Evidence is presented to illustrate aspects of the operation of the apprentice system. For centuries aspiring surgeons, barber surgeons and apothecaries, and a few physicians were trained under the apprentice system, a method of education through actual experience that of course was also employed in a wide array of other crafts and trades from armor making to wool selling. ' In London a boy was not supposed to become an apprentice until the age of fourteen, and he was usually indentured for seven years to a master of his craft. His apprenticeship and his subsequent admission, if approved, to the profession or trade were regulated by the guild. The system was subject to many abuses, in particular the exploitation of boys and girls indentured by the parish because they were foundlings or otherwise charges of the parish. Local authorities often deemed it expedient to relieve the parish of support of such young people as quickly and as advantageously as possible. As a result, they might become apprentices as early as age seven and were overworked, underfed, and sometimes physically abused. Boys indentured by their families into a skilled trade such as surgery fared relatively much better [1]. Although we know something of how medical, surgical, and related apprenticeships were conducted,2 little specific information about the lives and duties of the boys so indentured seems to have been published. An opportunity to study several City of London Mayor's Court interrogatories involving apprentices to surgeons and apothecaries has revealed some interesting details about these young men and their teachers.3 A summary of one case has already been published [3]; six others dating from 1654 to 1684 will be considered here. 'As of 1967, there were 88 livery companies or guilds in the City of London.

21st century energy solutions. Coal and Power Systems FY2001 program briefing  

Science Conference Proceedings (OSTI)

The continued strength of American's economy depends on the availability of affordable energy, which has long been provided by the Nations rich supplies of fossil fuels. Forecasts indicate that fossil fuels will continue to meet much of the demand for economical electricity and transportation fuels for decades to come. It is projected that natural gas, oil, and coal will supply nearly 90% of US energy in 2020, with coal fueling around 50% of the electricity. It is essential to develop ways to achieve the objectives for a cleaner environment while using these low-cost, high-value fuels. A national commitment to improved technologies--for use in the US and abroad--is the solution. The Coal and Power Systems program is responding to this commitment by offering energy solutions to advance the clean, efficient, and affordable use of the Nations abundant fossil fuel resources. These solutions include: (1) Vision 21--A multi-product, pollution-free energy plant--producing electricity, fuels, and/or industry heat--could extract 80% or more of the energy value of coal and 85% or more of the energy value of natural gas; (2) Central Power Systems--Breakthrough turbines and revolutionary new gasification technologies that burn less coal and gas to obtain energy, while reducing emissions; (3) Distributed Generation--Fuel cell technology providing highly efficient, clean modular power; (4) Fuels--The coproduction of coal-derived transportation fuels and power from gasification-based technology; (5) Carbon Sequestration--Capturing greenhouse gases from the exhaust gases of combustion or other sources, or from the atmosphere itself, and storing them for centuries or recycling them into useful products; and (6) Advanced Research--Going beyond conventional thinking in the areas of computational science, biotechnology, and advanced materials.

Prospects for Universal Heat Mining: from a Jules Verne vision to a 21st century reality  

SciTech Connect

The extraction of heat or thermal energy from the Earth -- heat mining -- has the potential to play a major role as an energy supply technology for the 21st century. However, even if reservoir stimulation goals are achieved, the role of heat mining with today's energy prices and development costs is limited to only a small fraction of the earth's surface, specifically to geologically active regions where geothermal gradients are high. This paper examines the prospects for universal heat mining and the types of developments required to make it a reality. A generalized multi-parameter economic model was developed for optimizing the design and performance of hot dry rock (HDR) geothermal systems by linking an SQP nonlinear programming algorithm with a generalized HDR economic model. HDR system design parameters selected for optimization include well depth (or initial rock temperature), geofluid flow rate, number of fractures and injection temperature. The sensitivities of the optimized design parameters, HDR system performance, and levelized electricity price to average geothermal gradient, fractured area/volume, maximum allowable geofluid temperature, reservoir flow impedance, well deviation, and fracture separation have been investigated. Key technical and institutional obstacles to universal heat mining are discussed in a more general context. These include (1) developing methods for stimulating low permeability formations to provide sustained productivity with acceptable flow/pressure losses (2) dealing with barriers to change primary energy supply options when fossil energy resources are abundant and prices are low and (3) lowering the high drilling costs for developing the deep (>5 km) reservoirs required in low gradient areas. Advanced concepts in drilling technology that could lead to a linear as opposed to exponential relationship between cost and depth are discussed in light of their potential impact on heat mining.

MULTI-WAVELENGTH OBSERVATIONS OF THE ENDURING TYPE IIn SUPERNOVAE 2005ip AND 2006jd  

SciTech Connect

We present an observational study of the Type IIn supernovae (SNe IIn) 2005ip and 2006jd. Broadband UV, optical, and near-IR photometry, and visual-wavelength spectroscopy of SN 2005ip complement and extend upon published observations to 6.5 years past discovery. Our observations of SN 2006jd extend from UV to mid-infrared wavelengths, and like SN 2005ip, are compared to reported X-ray measurements to understand the nature of the progenitor. Both objects display a number of similarities with the 1988Z-like subclass of SN IIn including (1) remarkably similar early- and late-phase optical spectra, (2) a variety of high-ionization coronal lines, (3) long-duration optical and near-IR emission, and (4) evidence of cold and warm dust components. However, diversity is apparent, including an unprecedented late-time r-band excess in SN 2006jd. The observed differences are attributed to differences between the mass-loss history of the progenitor stars. We conclude that the progenitor of SN 2006jd likely experienced a significant mass-loss event during its pre-SN evolution akin to the great 19th century eruption of {eta} Carinae. Contrarily, as advocated by Smith et al., the circumstellar environment of SN 2005ip is found to be more consistent with a clumpy wind progenitor.

Can Early Type Galaxies Evolve from Fading the Disks of Late Types?  

E-Print Network (OSTI)

We examine whether early-type galaxies in clusters may have evolved from later types by the fading of their disks (e.g., as a result of ram-pressure stripping or strangulation) or by enhancement of the bulge luminosity (e.g., due to tidal interactions and mergers). For this purpose, we compare the bulge and disk luminosities of early- and late-type galaxies and of galaxies at different radial distances from the cluster center. We find that, in order for early-type galaxies, including S0s, to have evolved from late-type galaxies, their bulge luminosities must have been physically enhanced. Disk fading models cannot explain the differences observed. We then show that galaxy bulges are systematically brighter at small projected distances from the cluster center, while disk luminosities are uncorrelated with cluster-centric distance. Our results suggest that bulge enhancement, not disk fading, distinguishes early from late types and is thus at least partially responsible for the morphology-environment relation of bright cluster galaxies.

Timing of late Quaternary faulting in the 1954 Dixie Valley earthquake area, central Nevada  

Science Conference Proceedings (OSTI)

The 1954 Dixie Valley earthquake (M 6.9) in central Nevada produced about 3 m of total vertical displacement distributed across two principal fault zones along the east flank of the Stillwater Range. Most of the 1954 displacement was along the range-front fault with minor amounts on the piedmont fault zone, in contrast to an earlier Holocene displacement that was restricted to the piedmont fault. Detailed chronostratigraphic, exploratory drilling, and trenching studies indicate that faulting events have migrated back and forth between the range-front and piedmont fault zones in the late Quaternary. Prior to the 1954 earthquake, the range-front fault last ruptured in the late Pleistocene, during a large-magnitude event here called the IXL event. The northern half of the piedmont fault zone last ruptured between 1.5 and 6.8 ka during a large-magnitude event here called the Bend event. On the basis of 6 m total slip since the deposition of shoreline gravels at {approximately} 12 ka, the estimated Holocene vertical-slip rate is 0.5 mm/yr for the Dixie Valley rupture zone. Overlapping and migratory patterns of late Quaternary faulting indicate that the Dixie Valley zone does not fit a simple segmentation model.

This dissertation proposes ?ghost writer? as a new critical term for the ?author? in accordance with what Roland Barthes calls the ?death of the author.? For this purpose, the dissertation conjoins current gothic criticism, modern authorship theories, and studies of nineteenth-century American literature. Current gothic critics, in their endeavors to re-define the gothic as a serious genre that represents social, cultural, and historical anxieties and terrors, have obscured gothic authors? presence. This indistinct, ghostly authorial existence within gothic criticism becomes relevant to modern authorship theorists? reflection on the end of eighteenth-century sovereign and autarchic authorship due to the ever-interpretable text and ever-interpreting readers, by means of the self-effacing gothic writers in nineteenth-century America. American literary scholars agree on contemporary readers? increasing power to assess writers? performance. Gothic writers, especially susceptible to this power since the ambiguities of the gothic necessitate readers? active constructions, composed their texts without selfassumed authorial intentions. This dissertation considers how the century?s five most representative gothic writers re-configure the author as a ghost that should come into being by readers? belief in what it writes. Chapter I examines the common grounds between the aforementioned three fields in further detail and illuminates the exigency of the ghost writer. Chapter II discusses Charles Brockden Brown?s prototypical expos? in Wieland of Edward Young?s typically romantic formulation of the originary and possessive author. Chapter III shows Edgar Allan Poe?s substantiation of Brown?s expos? through his conception of the author as a reader-made fiction in Arthur Gordon Pym. Chapter IV applies Poe?s author-fiction to Frederick Douglass and Louisa May Alcott, and investigates how those two marginalized writers overcome their spectrality with the aid of readers? sympathetic relation to their texts, Narrative of the Life of Frederick Douglass and ?Behind a Mask,? and subsequent validation of their author-ity. Chapter V explores the author?s willing self-transformation into the ghost writer in James?s The Turn of the Screw, and ponders how the ghost writer goes beyond the author?s death. By introducing the ghost writer, this dissertation ultimately aims to trace the pre-modern shift from the autonomous author to the heteronomous author.

H.M.S. Pallas: historical reconstruction of an 18th-century Royal Navy frigate  

E-Print Network (OSTI)

A 1998 joint survey undertaken by the Institute of Nautical Archaeology and Portuguese authorities located and identified the sunken remains of the Royal Navy frigate HMS Pallas (1757-1783) off of the Azorean island of São Jorge. Physical remains are so limited as to suggest that excavation would likely yield little new information. However, much documentary evidence has been preserved in Admiralty archives. Contemporary treatises about 18th-century British ship construction focus on glossaries of terms, scantling lists and design theory, and include only short sections on frigates insofar as they apply to those topics. They rarely address specific construction aspects. Most current works address individual aspects of ship construction for the period, but provide little significant detail about the frigate as a ship type. All of these works are useful and reliable, however none attempt to combine the ship with the crew, or pursue the complete history of one ship. As the flagship of a prototypical class, intended to address French superiority in cruiser design, it is reasonable to expect that a history of Pallas would exist with some analysis of how successfully these new frigates fulfilled the Royal Navy�s perceived need. However, to date there has been no attempt to consolidate the evidence of her 26-year career. This study provides a comprehensive history of a single ship from perceived need and conceived solution through design and construction. The ship�s logbooks and additional primary sources made it possible to accurately document and analyze Pallas� activities, maintenance, modifications, and ultimately to draw conclusions about the overall effectiveness of the frigate type. I began with basic background information to establish the perceived need for a new frigate type, followed by an examination of the conceived design solution. A partial set of admiralty drafts served as a foundation from which to develop a more complete set of construction plans, a spar plan, and rigging plans. Comprehensive research into life aboard Royal Navy warships of the period provided a social context within which to examine the service history of Pallas. Finally, a review of the maintenance record and the events leading up to her sinking enabled an informed assessment of how well HMS Pallas fulfilled the perceived need for which she was developed.

Examination of the role of nuclear deterrence in the 21st century: a systems analysis approach  

Science Conference Proceedings (OSTI)

Until very recently, an evaluation of US policy regarding deterrence and the role of its nuclear weapons arsenal as a deterrent has been largely absent in the public debate. With President's Obama embrace of a goal of a future world without nuclear weapons, issues of nuclear policy and deterrence have just recently risen to the forefront of policy discussions. The traditional role of US nuclear weapons-to deter the use of nuclear weapons by other states-endures, but is no longer unique nor even predominant. In an increasingly multi-polar world, the US now faces growing risks of nuclear weapons proliferation; the spread of weapons of mass destruction generally to non-state, substate and transnational actors; cyber, space, economic, environmental and resource threats along with the application of numerous other forms of 'soft power' in ways that are inimical to national security and to global stability. What concept of deterrence should the US seek to maintain in the 21st Century? That question remains fluid and central to the current debate. Recently there has been a renewed focusing of attention on the role of US nuclear weapons and a national discussion about what the underlying policy should be. In this environment, both the United States and Russia have committed to drastic reductions in their nuclear arsenals, while still maintaining forces sufficient to ensure unacceptable consequence in response to acts of aggression. Further, the declared nuclear powers have maintained that a limited nuclear arsenal continues to provide insurance against uncertain developments in a changing world. In this environment of US and Russian stockpile reductions, all declared nuclear states have reiterated the central role which nuclear weapons continue to provide for their supreme national security interests. Given this new environment and the challenges of the next several decades, how might the United States structure its policy and forces with regard to nuclear weapons? Many competing objectives have been stated across the spectrum of political, social, and military thought. These objectives include goals of ratification of the Comprehensive Test Ban Treaty, recommitment to further downsizing of the nuclear arsenal, embracing a long-term goal of the elimination of nuclear weapons, limitations on both the production complex and upgrades to nuclear weapons and delivery systems, and controls and constraints to limit proliferation of nuclear materials and weapons, particularly to rogue states and terrorist groups.

Terebinth resin in antiquity: possible uses in the Late Bronze Age Aegean region  

E-Print Network (OSTI)

The remains of an estimated one metric ton of terebinth resin, the yellowish, semi-fluid, aromatic resin of a Pistacia tree, were recently discovered on the Late Bronze Age shipwreck site at Uluburun, Turkey. The resin was carried in an estimated 130 Canaanite amphoras, as part of a rich and diverse cargo that included eleven metric tons of copper and tin, as well as other raw materials, tools, weapons and luxury goods on a ship journeying to some destination west or south of Uluburun. This is the largest single deposit of terebinth resin from antiquity ever found, and the first to be identified by modern analytical methods. The botanical origin of the resin is thought to be Pistacia atlantica, but the Pistacia genus includes many resin-producing trees, all of which have been well known and economically important from ancient times to the present. The sources and characteristics of modern terebinth resin are described, followed by a discussion of Pistacia trees and their many products--resin, fruits, leaves, bark, wood and galls. Some possible uses of terebinth resin in the Late Bronze Aegean region are then explored, as this area is likely to have been one of the intended destinations of the Uluburun ship. A discussion of the accepted translation of the Linear B word ki-ta-no as the fruits of the terebinth tree demonstrates that the word might refer to any of the products of the terebinth tree, not only fruits or, as was suggested after the discovery of the Uluburun cargo, resin. The ideogram *123 usually associated with ki-ta-no indicates a dry good, and is often considered to signify an "aromatic"; all products of the terebinth tree can be characterized as dry goods, and all have aromatic and astringent properties. The evidence for the use of terebinth resin in the perfumed oil industry and as incense in Late Bronze Age Greece is then briefly surveyed. The Late Bronze Age evidence from the Aegean region is scanty, but parallels from other regions and later periods allow the tentative conclusion that terebinth resin might have been used for both of these purposes. Confirmation requires discovery and analysis of residues.

Hydrogen generation during IDMS demonstrations of the Late Washing and Nitric Acid flowsheets  

DOE Green Energy (OSTI)

Recently, Late Washing (LW) and Nitric Acid (NA) flowsheets, developed respectively for the DWPF at Savannah River Technology Center SPC and CPC, were demonstrated in the one-fifth scale DWPF pilot facilities, PHEF and IDMS. Using the LW flowsheet, four runs in the PHEF produced enough PHA for two runs in the IDMS (denoted by PX4 and PX5). One of the objectives of these IDMS runs was to obtain peak hydrogen generation rates and compare them to the peak hydrogen generation rate design basis obtained from a previous IDMS run, based on the HAN and Formic Acid (HAN-FA) flowsheets.

Probabilistic accident consequence uncertainty analysis -- Late health effects uncertain assessment. Volume 2: Appendices  

SciTech Connect

The development of two new probabilistic accident consequence codes, MACCS and COSYMA, was completed in 1990. These codes estimate the consequence from the accidental releases of radiological material from hypothesized accidents at nuclear installations. In 1991, the US Nuclear Regulatory Commission and the Commission of the European Communities began cosponsoring a joint uncertainty analysis of the two codes. The ultimate objective of this joint effort was to systematically develop credible and traceable uncertainty distributions for the respective code input variables. A formal expert judgment elicitation and evaluation process was identified as the best technology available for developing a library of uncertainty distributions for these consequence parameters. This report focuses on the results of the study to develop distribution for variables related to the MACCS and COSYMA late health effects models. This volume contains appendices that include (1) a summary of the MACCS and COSYMA consequence codes, (2) the elicitation questionnaires and case structures, (3) the rationales and results for the expert panel on late health effects, (4) short biographies of the experts, and (5) the aggregated results of their responses.

Late Time Observations of the Afterglow and Environment of GRB 030329  

DOE Green Energy (OSTI)

We present Very Long Baseline Interferometry (VLBI) observations 217 days after the {gamma}-ray burst of 2003 March 29. These observations provide further measurements of the size and position of GRB 030329 that are used to constrain the expansion rate and proper motion of this nearby GRB. The expansion rate appears to be slowing down with time, favoring expansion into a constant density interstellar medium, rather than a circumstellar wind with an r{sup -2} density profile. We also present late time Arecibo observations of the redshifted Hi and OH absorption spectra towards GRB 030329. No absorption (or emission) is seen allowing us to place limits on the atomic neutral hydrogen of N{sub H} < 8.5 x 10{sup 20} cm{sup -2}, and molecular hydrogen of N{sub H{sub 2}} < 1.4 x 10{sup 22} cm{sup -2}. Finally, we present VLA limits on the radio polarization from the afterglow of <2% at late times.

Nuclear criticality safety evaluation -- DWPF Late Wash Facility, Salt Process Cell and Chemical Process Cell  

SciTech Connect

The Savannah River Site (SRS) High Level Nuclear Waste will be vitrified in the Defense Waste Processing Facility (DWPF) for long term storage and disposal. This is a nuclear criticality safety evaluation for the Late Wash Facility (LWF), the Salt Processing Cell (SPC) and the Chemical Processing Cell (CPC). of the DWPF. Waste salt solution is processed in the Tank Farm In-Tank Precipitation (ITP) process and is then further washed in the DWPF Late Wash Facility (LWF) before it is fed to the DWPF Salt Processing Cell. In the Salt Processing Cell the precipitate slurry is processed in the Precipitate Reactor (PR) and the resultant Precipitate Hydrolysis Aqueous (PHA) produce is combined with the sludge feed and frit in the DWPF Chemical Process Cell to produce a melter feed. The waste is finally immobilized in the Melt Cell. Material in the Tank Farm and the ITP and Extended Sludge processes have been shown to be safe against a nuclear criticality by others. The precipitate slurry feed from ITP and the first six batches of sludge feed are safe against a nuclear criticality and this evaluation demonstrates that the processes in the LWF, the SPC and the CPC do not alter the characteristics of the materials to compromise safety.

The Importance of Establishing and Maintaining Continuity of Knowledge during 21st Century Nuclear Fuel Cycle Activities  

SciTech Connect

During this century, the entire nuclear fuel cycle will expand and become increasingly more global, taxing both the resources and capabilities of the International Atomic Energy Agency (IAEA) to maintain an effective Continuity of Knowledge (CoK) and its ability to provide timely detection of diversion. Uranium that currently is mined and milled in one country will be converted, enriched, and fabricated into fuel for reactors in an expanding set of new countries. This expansion will make it harder to guarantee that regional activities stay regional and that diversion detection is timely unless new and sustainable tools are developed to improve inspector effectiveness. To deal with this emerging reality, the IAEA must increase its use of unattended monitoring and employ new tools and methods that enhance CoK during all phases of the fuel cycle. This approach will help provide useful information to aid in detecting undeclared activities and create opportunities for timely and appropriate responses to events well before they enter phases of greater concern (e.g., enrichment). The systems that maintain CoK of safeguarded assets rely on containment and surveillance (C/S) technologies. The 21st century fuel cycle will require increased use of these technologies and systems, plus greater implementation of unattended systems that can securely collect data when inspectors are not present.

Results from the 2010 INMM International Containment and Surveillance Workshop focused on Concepts for the 21st Century  

Science Conference Proceedings (OSTI)

The Institute of Nuclear Materials Management (INMM) held an International Workshop, 'Containment & Surveillance (C/S): Concepts for the 21st Century,' June 6-11, 2010, at the Oak National Laboratory, in Oak Ridge, Tennessee. The National Nuclear Security Administration (NNSA) Office of Nonproliferation Research and Development and Office of Nonproliferation and International Security sponsored the event. The workshop focused on determining concepts and needs for 21st century containment and surveillance (C/S) systems that support International Atomic Energy Agency (IAEA) safeguards and future arms control agreements. Panel discussions by subject matter experts and international practitioners addressed daily topical themes encompassing the following areas of C/S: authentication; tagging, sealing, and containment verification; and surveillance systems. Each panel discussion was followed by a question-and-answer session with the audience and an afternoon breakout session. The facilitated breakout sessions were used to compile information and determine future needs. Individuals attending the workshop included C/S experts and practitioners; IAEA and arms control inspectors; technology providers; vendors; students; and individuals with an interest in, or desire to learn about, future C/S system needs. The primary goal of the workshop was to produce a document that details the future research and development needs for C/S systems that support nuclear safeguards and arms control missions. This talk will present a compilation of the information obtained from breakout sessions at the workshop.

Laboratories for the 21st Century: Best Practices; Energy Recovery in Laboratory Facilities (Brochure)  

SciTech Connect

This guide regarding energy recovery is one in a series on best practices for laboratories. It was produced by Laboratories for the 21st Century ('Labs 21'), a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. Laboratories typically require 100% outside air for ventilation at higher rates than other commercial buildings. Minimum ventilation is typically provided at air change per hour (ACH) rates in accordance with codes and adopted design standards including Occupational Safety and Health Administration (OSHA) Standard 1910.1450 (4 to 12 ACH - non-mandatory) or the 2011 American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Applications Handbook, Chapter 16 - Laboratories (6 to 12 ACH). While OSHA states this minimum ventilation rate 'should not be relied on for protection from toxic substances released into the laboratory' it specifically indicates that it is intended to 'provide a source of air for breathing and for input to local ventilation devices (e.g., chemical fume hoods or exhausted bio-safety cabinets), to ensure that laboratory air is continually replaced preventing the increase of air concentrations of toxic substances during the working day, direct air flow into the laboratory from non-laboratory areas and out to the exterior of the building.' The heating and cooling energy needed to condition and move this outside air can be 5 to 10 times greater than the amount of energy used in most office buildings. In addition, when the required ventilation rate exceeds the airflow needed to meet the cooling load in low-load laboratories, additional heating energy may be expended to reheat dehumidified supply air from the supply air condition to prevent over cooling. In addition to these low-load laboratories, reheat may also be required in adjacent spaces such as corridors that provide makeup air to replace air being pulled into negative-pressure laboratories. Various types of energy recovery devices and systems can substantially reduce heating and cooling energy required for conditioning spaces in laboratories. Heating and cooling systems can be downsized when energy recovery is used because these systems reduce peak heating and cooling requirements. Heating and cooling systems can also be downsized by capturing heat generated in high-load spaces and transferring it to spaces requiring reheat. There are many opportunities for energy recovery in laboratories. This guide includes descriptions of several air-to-air energy recovery devices and methods, such as using enthalpy wheels (Figure 1), heat pipes, or run-around loops in new construction. These devices generally recover energy from exhaust air. This recovered energy is used to precondition supply air during both cooling and heating modes of operation. In addition to air-to-air energy recovery options, this guide includes a description of a water-to-water heat recovery system that collects heat from high-load spaces and transfers it to spaces that require reheat. While air-to-air recovery devices provide significant energy reduction, in some laboratory facilities the amount of energy available in the exhaust air exceeds the pre-heat and pre-cooling needed to maintain supply air conditions. During these periods of time, controls typically reduce the energy recovery capacity to match the reduced load. If the energy recovered in the exhaust is not needed then it is rejected from the facility. By using a water-to-water recovery system, it is possible to significantly reduce overall building energy use by reusing heating or cooling energy generated in the building before it is rejected to the outdoors. Laboratory managers are encouraged to perform a life-cycle cost analysis of an energy-recovery technology to determine the feasibility of its application in their laboratory. Usually, the shortest payback periods occur when the heating and cooling load reduction provided by an energy recovery system allows the laboratory to install and use smaller heating (e.g., hot water or steam) and cooling (e.g., c

LATE-TIME LIGHT CURVES OF TYPE II SUPERNOVAE: PHYSICAL PROPERTIES OF SUPERNOVAE AND THEIR ENVIRONMENT  

Science Conference Proceedings (OSTI)

We present BVRIJHK-band photometry of six core-collapse supernovae, SNe 1999bw, 2002hh, 2003gd, 2004et, 2005cs, and 2006bc, measured at late epochs (>2 yr) based on the Hubble Space Telescope (HST), and the Gemini North, and WIYN telescopes. We also show the JHK light curves of supernova impostor SN 2008S up to day 575 because it was serendipitously in our SN 2002hh field of view. Of our 43 HST observations in total, 36 observations are successful in detecting the light from the SNe alone and measuring magnitudes of all the targets. HST observations show a resolved scattered light echo around SN 2003gd at day 1520 and around SN 2002hh at day 1717. Our Gemini and WIYN observations detected SNe 2002hh and 2004et as well. Combining our data with previously published data, we show VRIJHK-band light curves and estimate decline magnitude rates at each band in four different phases. Our prior work on these light curves and other data indicate that dust is forming in our targets from days {approx}300 to 400, supporting SN dust formation theory. In this paper we focus on other physical properties derived from late-time light curves. We estimate {sup 56}Ni masses for our targets (0.5-14 Multiplication-Sign 10{sup -2} M{sub Sun }) from the bolometric light curve of each of days {approx}150-300 using SN 1987A as a standard (7.5 Multiplication-Sign 10{sup -2} M{sub Sun }). The flattening or sometimes increasing fluxes in the late-time light curves of SNe 2002hh, 2003gd, 2004et, and 2006bc indicate the presence of light echoes. We estimate the circumstellar hydrogen density of the material causing the light echo and find that SN 2002hh is surrounded by relatively dense materials (n(H) >400 cm{sup -3}) and SNe 2003gd and 2004et have densities more typical of the interstellar medium ({approx}1 cm{sup -3}). We analyze the sample as a whole in the context of physical properties derived in prior work. The {sup 56}Ni mass appears well correlated with progenitor mass with a slope of 0.31 Multiplication-Sign 10{sup -2}, supporting the previous work by Maeda et al., who focus on more massive Type II SNe. The dust mass does not appear to be correlated with progenitor mass.

Determination of Earths transient and equilibrium climate sensitivities from observations over the twentieth century: Strong dependence on assumed forcing  

Science Conference Proceedings (OSTI)

Relations among observed changes in global mean surface temperature, ocean heat content, ocean heating rate, and calculated radiative forcing, all as a function of time over the twentieth century, that are based on a two-compartment energy balance model, are used to determine key properties of Earth's climate system. The increase in heat content of the world ocean, obtained as the average of several recent compilations, is found to be linearly related to the increase in global temperature over the period 1965-2009; the slope, augmented to account for additional heat sinks, which is an effective heat capacity of the climate system, is 21.8 {+-} 2.1 W year m{sup -2} K{sup -1} (one sigma), equivalent to the heat capacity of 170 m of seawater (for the entire planet) or 240 m for the world ocean. The rate of planetary heat uptake, determined from the time derivative of ocean heat content, is found to be proportional to the increase in global temperature relative to the beginning of the twentieth century with proportionality coefficient 1.05 {+-} 0.06 W m{sup -2} K{sup -1}. Transient and equilibrium climate sensitivities were evaluated for six published data sets of forcing mainly by incremental greenhouse gases and aerosols over the twentieth century as calculated by radiation transfer models; these forcings ranged from 1.1 to 2.1 W m{sup -2}, spanning much of the range encompassed by the 2007 assessment of the Intergovernmental Panel on Climate Change (IPCC). For five of the six forcing data sets, a rather robust linear proportionality obtains between the observed increase in global temperature and the forcing, allowing transient sensitivity to be determined as the slope. Equilibrium sensitivities determined by two methods that account for the rate of planetary heat uptake range from 0.31 {+-} 0.02 to 1.32 {+-} 0.31 K (W m{sup -2}){sup -1} (CO{sub 2} doubling temperature 1.16 {+-} 0.09-4.9 {+-} 1.2 K), more than spanning the IPCC estimated 'likely' uncertainty range, and strongly anticorrelated with the forcing used to determine the sensitivities. Transient sensitivities, relevant to climate change on the multidecadal time scale, are considerably lower, 0.23 {+-} 0.01 to 0.51 {+-} 0.04 K (W m{sup -2}){sup -1}. The time constant characterizing the response of the upper ocean compartment of the climate system to perturbations is estimated as about 5 years, in broad agreement with other recent estimates, and much shorter than the time constant for thermal equilibration of the deep ocean, about 500 years.

Modeling the effects of late cycle oxygen enrichment on diesel engine combustion and emissions.  

DOE Green Energy (OSTI)

A multidimensional simulation of Auxiliary Gas Injection (AGI) for late cycle oxygen enrichment was exercised to assess the merits of AGI for reducing the emissions of soot from heavy duty diesel engines while not adversely affecting the NO{sub x} emissions of the engine. Here, AGI is the controlled enhancement of mixing within the diesel engine combustion chamber by high speed jets of air or another gas. The engine simulated was a Caterpillar 3401 engine. For a particular operating condition of this engine, the simulated soot emissions of the engine were reduced by 80% while not significantly affecting the engine-out NO{sub x} emissions compared to the engine operating without AGI. The effects of AGI duration, timing, and orientation are studied to confirm the window of opportunity for realizing lower engine-out soot while not increasing engine out NO{sub x} through controlled enhancement of in-cylinder mixing. These studies have shown that this window occurs during the late combustion cycle, from 20 to 60 crank angle degrees after top-dead-center. During this time, the combustion chamber temperatures are sufficiently high that soot oxidation increases in response in increased mixing, but the temperature is low enough that NO{sub x} reactions are quenched. The effect of the oxygen composition of the injected air is studied for the range of compositions between 21% and 30% oxygen by volume. This is the range of oxygen enrichment that is practical to produce from an air separation membrane. Simulations showed that this level of oxygen enrichment is insufficient to provide an additional benefit by either increasing the level of soot oxidation or prolonging the window of opportunity for increasing soot oxidation through enhanced mixing.

A New Biology for the 21st Century; Ensuring the United States Leads the Coming Biology Revolution  

SciTech Connect

In July, 2008, the National Institutes of Health (NIH), National Science Foundation (NSF), and Department of Energy (DOE) asked the National Research Council’s Board on Life Sciences to convene a committee to examine the current state of biological research in the United States and recommend how best to capitalize on recent technological and scientific advances that have allowed biologists to integrate biological research findings, collect and interpret vastly increased amounts of data, and predict the behavior of complex biological systems. From September 2008 through July of 2009, a committee of 16 experts from the fields of biology, engineering and computational science undertook to delineate those scientific and technological advances and come to a consensus on how the U.S. might best capitalize on them. This report, authored by the Committee on a New Biology for the 21st Century, describes the committee’s work and conclusions.

The Need for a Strong Science and Technology Program in the Nuclear Weapons Complex for the 21st Century  

Science Conference Proceedings (OSTI)

In this paper I argue for the need for a strong Science and Technology program in the Nuclear Weapons Complex as the basis for maintaining a credible deterrence capability. The current Nuclear Posture Review establishes a New Triad as the basis for the United States deterrence strategy in a changing security environment. A predictive science capability is at the core of a credible National Nuclear Weapons program in the 21st Century. In absence of nuclear testing, the certification of our current Nuclear Weapons relies on predictive simulations and quantification of the associated simulation uncertainties. In addition, a robust nuclear infrastructure needs an active research and development program that considers all the required nuclear scenarios, including new configurations for which there is no nuclear test data. This paper also considers alternative positions to the need for a Science and Technology program in the Nuclear Weapons complex.

Late miocene/pliocene origin of the inverted metamorphism of the Central Himalaya  

SciTech Connect

The spatial association of intracontinental thrusting and inverted metamorphism, recognized in the Himalaya more than a century ago, has inspired continuing efforts to identify their causal relationship. Perhaps the best known sequence of inverted metamorphism is that found immediately beneath the Himalayan Main Central Thrust (MCT), generally thought to have been active during the Early Miocene. It has been widely assumed that the pattern of inverted metamorphism also developed at that time. Using a new approach, in situ Th-Pb dating of monazite included in garnet, we have discovered that the peak metamorphic recrystallization recorded in the footwall of the MCT fault occurred at ca. 5 Ma. The apparent inverted metamorphism resulted from activation of a broad shear zone beneath the MCT zone which juxtaposed two right-way-up metamorphic sequences. Recognition of this remarkably youthful phase of metamorphism resolves outstanding problems in Himalayan tectonics, such as why the MCT (and not the more recently initiated thrusts) marks the break in slope of the present day mountain range, and transcends others, such as the need for exceptional conditions to explain Himalayan anatexis.

Global Biofuel Use, 1850-2000.  

Science Conference Proceedings (OSTI)

This paper presents annual, country-level estimates of biofuel use for the period 1850-2000. We estimate that global biofuel consumption rose from about 1000 Tg in 1850 to 2460 Tg in 2000, an increase of 140%. In the late 19th century, biofuel consumption in North America was very high, {approx}220-250 Tg/yr, because widespread land clearing supplied plentiful fuelwood. At that time biofuel use in Western Europe was lower, {approx}180-200 Tg/yr. As fossil fuels became available, biofuel use in the developed world fell. Compensating changes in other parts of the world, however, caused global consumption to remain remarkably stable between 1850 and 1950 at {approx}1200 {+-} 200 Tg/yr. It was only after World War II that biofuel use began to increase more rapidly in response to population growth in the developing world. Between 1950 and 2000, biofuel use in Africa, South Asia, and Southeast Asia grew by 170%, 160%, and 130%, respectively.

LATE-TIME SPECTRAL OBSERVATIONS OF THE STRONGLY INTERACTING TYPE Ia SUPERNOVA PTF11kx  

SciTech Connect

PTF11kx was a Type Ia supernova (SN Ia) that showed time-variable absorption features, including saturated Ca II H and K lines that weakened and eventually went into emission. The strength of the emission component of H{alpha} gradually increased, implying that the SN was undergoing significant interaction with its circumstellar medium (CSM). These features, and many others, were blueshifted slightly and showed a P-Cygni profile, likely indicating that the CSM was directly related to, and probably previously ejected by, the progenitor system itself. These and other observations led Dilday et al. to conclude that PTF11kx came from a symbiotic nova progenitor like RS Oph. In this work we extend the spectral coverage of PTF11kx to 124-680 rest-frame days past maximum brightness. The late-time spectra of PTF11kx are dominated by H{alpha} emission (with widths of full width at half-maximum intensity Almost-Equal-To 2000 km s{sup -1}), strong Ca II emission features ({approx}10,000 km s{sup -1} wide), and a blue 'quasi-continuum' due to many overlapping narrow lines of Fe II. Emission from oxygen, He I, and Balmer lines higher than H{alpha} is weak or completely absent at all epochs, leading to large observed H{alpha}/H{beta} intensity ratios. The H{alpha} emission appears to increase in strength with time for {approx}1 yr, but it subsequently decreases significantly along with the Ca II emission. Our latest spectrum also indicates the possibility of newly formed dust in the system as evidenced by a slight decrease in the red wing of H{alpha}. During the same epochs, multiple narrow emission features from the CSM temporally vary in strength. The weakening of the H{alpha} and Ca II emission at late times is possible evidence that the SN ejecta have overtaken the majority of the CSM and agrees with models of other strongly interacting SNe Ia. The varying narrow emission features, on the other hand, may indicate that the CSM is clumpy or consists of multiple thin shells.

EVALUATING SHORT-TERM CLIMATE VARIABILITY IN THE LATE HOLOCENE OF THE NORTHERN GREAT PLAINS  

Science Conference Proceedings (OSTI)

This literature study investigated methods and areas to deduce climate change and climate patterns, looking for short-term cycle phenomena and the means to interpret them. Many groups are actively engaged in intensive climate-related research. Ongoing research might be (overly) simplified into three categories: (1) historic data on weather that can be used for trend analysis and modeling; (2) detailed geological, biological (subfossil), and analytical (geochemical, radiocarbon, etc.) studies covering the last 10,000 years (about since last glaciation); and (3) geological, paleontological, and analytical (geochemical, radiometric, etc.) studies over millions of years. Of importance is our ultimate ability to join these various lines of inquiry into an effective means of interpretation. At this point, the process of integration is fraught with methodological troubles and misconceptions about what each group can contribute. This project has met its goals to the extent that it provided an opportunity to study resource materials and consider options for future effort toward the goal of understanding the natural climate variation that has shaped our current civilization. A further outcome of this project is a proposed methodology based on ''climate sections'' that provides spatial and temporal correlation within a region. The method would integrate cultural and climate data to establish the climate history of a region with increasing accuracy with progressive study and scientific advancement (e. g., better integration of regional and global models). The goal of this project is to better understand natural climatic variations in the recent past (last 5000 years). The information generated by this work is intended to provide better context within which to examine global climate change. The ongoing project will help to establish a basis upon which to interpret late Holocene short-term climate variability as evidenced in various studies in the northern Great Plains, northern hemisphere, and elsewhere. Finally these data can be integrated into a history of climate change and predictive climate models. This is not a small undertaking. The goals of researchers and the methods used vary considerably. The primary task of this project was literature research to (1) evaluate existing methodologies used in geologic climate change studies and evidence for short-term cycles produced by these methodologies and (2) evaluate late Holocene climate patterns and their interpretations.

Late Paleocene paleoenvironmental gradients in Wilcox Group strata, Big Brown Mine, Texas  

E-Print Network (OSTI)

The Wilcox Group in Texas has been recognized as an important oil and gas reservoir for much of this century, and for the last 30 years has been commercially mined for its extensive shallow lignitic coals. More recently, exploration for coalbed methane in the Gulf Coast has focused in this area. For this new play to become successful, more information on the stratigraphy and depositional environments of the Wilcox Group is needed. The Wilcox Group in the Gulf Coast has been interpreted as primarily fluvial-deltaic in origin; however, since the 1980s, much evidence for tidal control on the deposition of the upper Wilcox (Calvert Bluff Formation) has been compiled. New data from the examination of sediments and fossils contained in the upper Wilcox Calvert Bluff Formation in and near the Texas Utilities' Big Brown Mine confirm that significant marine influence was present at the time of deposition. Most fine-grained sediments contain flaser, rippled, and laminated bedding, and palynological assemblages from non-coal sediments commonly contain Paleocene-Eocene marine dinoflagellates as well as brackish-water indicator palynomorphs. Sand deposits also contain marine dinoflagellates and are in gradational contact with underlying fine-grained sediments. Channel-fill deposits present in the mine area are similar to known examples of tidal flat and estuarine channels. These features indicate that brackish to marine conditions existed during much of the deposition of the upper Wilcox Group in northeastern Texas. The presence of non-fluvial-deltaic deposition in the upper Wilcox Group has implications for the location and extent of the coals, which will aid in the location of coalbed methane reservoirs.

Land use in the late prehistoric Post Oak Savannah of Texas  

E-Print Network (OSTI)

The purpose of this study is to look at land use in the Late Prehistoric period in the Post Oak Savannah of Texas. The goal is to determine the geographic extent of agriculture and what inhibits the extent and degree. In order to accomplish this, data are compiled on the environment, the ethnohistoric record, and the archaeology of the Post Oak Savannah. It is expected that boundaries can be found between areas of hunter-gatherers and agriculturalists. In order to evaluate the role of the environment, the climate, vegetation, geology, soils, and fauna are examined. Data from the journals and diaries of early European explorers are compiled and analyzed to determine the extent of agriculture during the Historic period. The final source of information is the archaeological record. Ceramic assemblages are analyzed and the information used to determine a possible boundary. Information from these diverse data all point to the Brazos River basin as the boundary between agricultural and bunter-gatherer land use in the Post Oak Savannah.

CO{sub 2} EOR starts in late stage of waterflood  

SciTech Connect

The Postle field carbon dioxide flood marks the first time anyone in the industry has attempted a major CO{sub 2} enhanced oil recovery EOR project at such a late stage in a waterflooded field. Prior to CO{sub 2} injection Postle produced oil with a 98% water cut. Mobil began injecting CO{sub 2} into the Postle on Nov. 15, 1995. The Postle field, discovered in 1958 in the Oklahoma Panhandle near Guymon, had produced about 92 million bbl of oil under primary and waterflood production. Waterflooding started in 1967. Oil production peaked at about 22,000 bo/d in 1970 and averaged about 2,000 bo/d when CO{sub 2} injection began at a rate of 35 MMscfd. The paper describes Mobil`s plans for the CO{sub 2} injection, the CO{sub 2} process, project installations, and Mobil`s experience with CO{sub 2} injection in other fields.

Building organizational technical capabilities: a new approach to address the office of environmental management cleanup challenges in the 21. century  

Science Conference Proceedings (OSTI)

The United States Department of Energy (DOE), Office of Environmental Management (EM) is responsible for the nations nuclear weapons program legacy wastes cleanup. The EM cleanup efforts continue to progress, however the cleanup continues to be technologically complex, heavily regulated, long-term, and a high life cycle cost estimate (LCCE) effort. Over the past few years, the EM program has undergone several changes to accelerate its cleanup efforts with varying degrees of success. Several cleanup projects continued to experience schedule delays and cost growth. The schedule delays and cost growth have been attributed to several factors such as changes in technical scope, regulatory and safety considerations, inadequacy of acquisition approach and project management. This article will briefly review the background and schools of thought on strategic management and organizational change practiced in the United States over the last few decades to improve an organisation's competitive edge and cost performance. The article will briefly review examples such as the change at General Electric, and the recent experience obtained from the nuclear industry, namely the long-term response to the 1986 Chernobyl accident. The long-term response to Chernobyl, though not a case of organizational change, could provide some insight in the strategic management approaches used to address people issues. The article will discuss briefly EM attempts to accelerate cleanup over the past few years, and the subsequent paradigm shift. The paradigm shift targets enhancing and/or creating organizational capabilities to achieve cost savings. To improve its ability to address the 21. century environmental cleanup challenges and achieve cost savings, EM has initiated new corporate changes to develop new and enhance existing capabilities. These new and enhanced organizational capabilities include a renewed emphasis on basics, especially technical capabilities including safety, project management, acquisition management and people. The new enhanced organizational capabilities coupled with more effective communications; oversight and decision-making processes are expected to help EM meet the 21. century challenges. This article will focus on some of the initiatives to develop and enhance organizational technical capabilities. Some of these development initiatives are a part of DOE corporate actions to respond to the Defense Nuclear Facilities Safety Board (DNFSB) recommendations 93-3 and 2004-1. Other development initiatives have been tailored to meet EM specific needs for organizational capabilities such as case studies analysis and cost estimating. (authors)

Judging Edward Teller: A Closer Look at One of the Most Influential Scientists of the Twentieth Century  

SciTech Connect

Much has been written about Edward TEller, but little of it is objective. Given, on the one hand, his position as one of the most inventive theoretical physicists of the 20th century, and on the other, his central role in the development and advocacy of thermonuclear weapons, one might imagine it impossible at this point in history to write a scholarly, impartial account of Teller's life and his impact. Now, however, Istvan Hargittai, a prominent Hungarian physical chemist and historian of science, has written a balanced, thoughtful, and beautifully research biography that comes closest. Hargittai is uniquely qualified for this difficult task. Coming a generation and a half later from a similar Hungarian-Jewish background, Hargittai understands well the influences and terrible events that shaped Teller. The advent of virulent, political anti-Semitism, first in Hungary and then in Germany, made Teller twice a refugee. Both Teller and Hargittai lost close family in the Holocaust; Hargittai was himself liberated from a Nazi concentration camp as a child. While Teller was in the US by then, his and Hargittai's surviving family members in Hungary suffered mistreatment at the hands of the postwar Hungarian Communist dictatorship. Hargittai's informed Eastern European perspective also provides a fresh viewpoint to the cold war context of the second half of Teller's career. Furthermore, Hargittai's own scientific work in molecular structure clearly makes him appreciate of Teller's breakthroughs in that field in the 1930s.

Laboratories for the 21st Century: Best Practices; Modeling Exhaust Dispersion for Specifying Acceptable Exhaust/Intake Design (Brochure)  

Science Conference Proceedings (OSTI)

This guide provides general information on specifying acceptable exhaust and intake designs. It also provides various quantitative approaches that can be used to determine expected concentration levels resulting from exhaust system emissions. In addition, the guide describes methodologies that can be employed to operate laboratory exhaust systems in a safe and energy efficient manner by using variable air volume (VAV) technology. The guide, one in a series on best practices for laboratories, was produced by Laboratories for the 21st Century (Labs21), a joint program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). Geared toward architects, engineers, and facility managers, the guides contain information about technologies and practices to use in designing, constructing, and operating safe, sustainable, high-performance laboratories. Studies show a direct relationship between indoor air quality and the health and productivity of building occupants. Historically, the study and protection of indoor air quality focused on emission sources emanating from within the building. For example, to ensure that the worker is not exposed to toxic chemicals, 'as manufactured' and 'as installed' containment specifications are required for fume hoods. However, emissions from external sources, which may be re-ingested into the building through closed circuiting between the building's exhaust stacks and air intakes, are an often overlooked aspect of indoor air quality.

Late universe dynamics with scale-independent linear couplings in the dark sector  

SciTech Connect

We explore the dynamics of cosmological models with two coupled dark components with energy densities {rho}{sub A} and {rho}{sub B} and constant equation of state (EOS) parameters w{sub A} and w{sub B}. We assume that the coupling is of the form Q=Hq({rho}{sub A},{rho}{sub B}), so that the dynamics of the two components turns out to be scale independent, i.e. does not depend explicitly on the Hubble scalar H. With this assumption, we focus on the general linear coupling q=q{sub o}+q{sub A}{rho}{sub A}+q{sub B}{rho}{sub B}, which may be seen as arising from any q({rho}{sub A},{rho}{sub B}) at late time and leads in general to an effective cosmological constant. In the second part of the paper we consider observational constraints on the form of the coupling from SN Ia data, assuming that one of the components is cold dark matter (CDM), i.e. w{sub B}=0, while for the other the EOS parameter can either have a standard (w{sub A}>-1) or phantom (w{sub A}<-1) value. We find that the constant part of the coupling function is unconstrained by SN Ia data and, among typical linear coupling functions, the one proportional to the dark energy density {rho}{sub A} is preferred in the strong coupling regime, |q{sub A}|>1. Models with phantom w{sub A} favor a positive coupling function, increasing {rho}{sub A}. In models with standard w{sub A}, not only a negative coupling function is allowed, transferring energy to CDM, but the uncoupled subcase falls at the border of the likelihood.

Quantitative Ultrasonic Evaluation of Radiation-Induced Late Tissue Toxicity: Pilot Study of Breast Cancer Radiotherapy  

Science Conference Proceedings (OSTI)

Purpose: To investigate the use of advanced ultrasonic imaging to quantitatively evaluate normal-tissue toxicity in breast-cancer radiation treatment. Methods and Materials: Eighteen breast cancer patients who received radiation treatment were enrolled in an institutional review board-approved clinical study. Radiotherapy involved a radiation dose of 50.0 to 50.4 Gy delivered to the entire breast, followed by an electron boost of 10.0 to 16.0 Gy delivered to the tumor bed. Patients underwent scanning with ultrasound during follow-up, which ranged from 6 to 94 months (median, 22 months) postradiotherapy. Conventional ultrasound images and radio-frequency (RF) echo signals were acquired from treated and untreated breasts. Three ultrasound parameters, namely, skin thickness, Pearson coefficient, and spectral midband fit, were computed from RF signals to measure radiation-induced changes in dermis, hypodermis, and subcutaneous tissue, respectively. Ultrasound parameter values of the treated breast were compared with those of the untreated breast. Ultrasound findings were compared with clinical assessment using Radiation Therapy Oncology Group (RTOG) late-toxicity scores. Results: Significant changes were observed in ultrasonic parameter values of the treated vs. untreated breasts. Average skin thickness increased by 27.3%, from 2.05 {+-} 0.22mm to 2.61 {+-} 0.52mm; Pearson coefficient decreased by 31.7%, from 0.41 {+-} 0.07 to 0.28 {+-} 0.05; and midband fit increased by 94.6%, from -0.92 {+-} 7.35 dB to 0.87 {+-} 6.70 dB. Ultrasound evaluations were consistent with RTOG scores. Conclusions: Quantitative ultrasound provides a noninvasive, objective means of assessing radiation-induced changes to the skin and subcutaneous tissue. This imaging tool will become increasingly valuable as we continue to improve radiation therapy technique.

Implications for the creation of warm saline deep water: Late Paleocene reconstructions and global climate model simulations  

SciTech Connect

A global warming trend began during the late Paleocene that culminated in the early Eocene with the highest global temperatures of the Cenozoic. We have reconstructed late Paleocene surfacial boundary conditions and modeled atmospheric conditions using the Goddard Institute for Space Studies general circulation model version II (GISS GCM II). These experiments were conducted to test the hypothesis that warm saline deep water formed during the late paleocene and to understand atmospheric circulation near the beginning of a period of global warming. The warming is attributed primarily to increased sea surface temperatures at high latitudes. The sensitivity of the climate to ocean temperature was tested using two sea surface temperature distributions, each delimited latitudinally by oxygen isotope values, but with different east-west gradients. The simulations discussed here contain several features unique among warm climate experiments. The first experiment (P-1) used latitudinally constant (zonal) sea surface temperatures. The zonally distributed sea surface temperatures strengthen the general circulation of the atmosphere. In particular, Hadley Cell circulation is intensified, leading to extremes of precipitation in the equatorial region and extreme evaporation across subtropical oceans. The unusual results prompted a second experiment with modern east-west sea surface temperature gradients superimposed and referred to as P-Gradient (P-Grad). 84 refs., 10 figs., 4 tabs.

Non-LTE Balmer line formation in late-type spectra: Effects of atomic processes involving hydrogen atoms  

E-Print Network (OSTI)

(*** abridged ***) Context: The wings of Balmer lines are often used as effective temperature diagnostics for late-type stars under the assumption they form in local thermodynamic equilibrium. Aims: Our goal is to investigate the non-LTE formation of Balmer lines in late-type stellar atmospheres, to establish if the assumption of LTE is justified. Furthermore, we aim to determine which collision processes are important for the problem; in particular, the role of collision processes with hydrogen atoms is investigated. Method: A model hydrogen atom for non-LTE calculations has been constructed accounting for various collision processes using the best available data from the literature. The processes included are inelastic collisions with electrons and hydrogen atoms, mutual neutralisation and Penning ionisation. Non-LTE calculations are performed, and the relative importance of the collision processes is investigated. Results: Our calculations show electron collisions alone are not sufficient to establish LTE for the formation of Balmer line wings. The role of inelastic collisions with neutral hydrogen is unclear. The available data for these processes is of questionable quality, and different prescriptions for the rate coefficents give significantly different results for the Balmer line wings. Conclusions: Improved calculations or experimental data are needed for excitation and, particularly, ionisation of hydrogen atoms in low-lying states by hydrogen atom impact at near threshold energies. Until such data are available, the assumption of LTE for the formation of Balmer line wings in late-type stars is questionable.

Drought over the past century in Texas and New Mexico: reducing inhomogeneities in long-term climate records via statistical methods to study drought  

E-Print Network (OSTI)

This research looks at the past century of Texas and New Mexico climate in order to create datasets sufficient for documenting climatic variations. Inhomogeneities in climate records are defined as variations in climatic records caused by factors other than weather and climate. While there are indirect methodologies for inferring climate records such as tree rings and ice cores, it is the instrumental network that constitutes the most spatially and temporally complete record of land surface climate since the onset of the Industrial Revolution. A statistical method by Sun and Peterson (2005a) called Inverse Weighting of Square Distance (IWSD) will be used to reduce the inhomogeneities in climate records. The National Weather Service Cooperative Observer Program (COOP) network of stations will be used for this analysis. A subset of the extensive COOP network, called the United States Historical Climate Network (USHCN), will be used as a foundation for this study. The analysis and resulting datasets from this climatic study show precipitation trends and periods of drought and will be useful for decisions regarding future policies on drought. The result of the interpolation process was the creation of several COOP and USHCN datasets. Several of the datasets were investigated to determine the spatial characteristics of precipitation over the 20th century in Texas and New Mexico. The datasets are in good agreement that the most severe drought period of the 20th century in Texas and New Mexico was in the 1950s. The frequency of pluvial periods was higher toward the end of the 20th century, with most USHCN stations showing an increasing trend when a linear regression analysis was done on each station's precipitation data.

Late Pleistocene Neandertal-Early Modern Human Population Dynamics: The Dental Evidence  

E-Print Network (OSTI)

Recent genetic studies have confirmed that there was admixture between African early modern humans and archaic populations throughout the Old World. In this dissertation, I examine European early modern human dental morphology to assess the evidence for Neandertal-human admixture. The focus of this study is not on the question of taxonomic designations of Late Pleistocene Homo, but rather on the interactions of these populations in Europe. This focus on gene flow itself redefines the Neandertal question. Rather than asking if Neandertals are a different species from H. sapiens, I focus on the nature of the interactions between archaic and modern populations, which is essential to understanding the history of modern H. sapiens regardless of species definitions. I recorded dental metric measurements and morphology observations on 85 fossil Neandertals and early modern humans and a recent modern human comparative sample of 330 Native Americans and Spaniards. I examined each trait distribution individually and through the use of Mahalanobis D2, mean measure of divergence, principle components analysis, discriminant function analysis, k-means cluster analysis, and a population genetics program, structure. Through these methods, I found evidence of admixture in the dental trait distributions of European early modern humans. However, it is not evident in traditional distance measures or cluster analyses. The earliest European modern humans do not follow the trend of dental reduction found throughout the Pleistocene and into the Holocene and do not uniformly classify with any fossil population in discriminant function analysis of metric traits. The non-metric trait sample size is too small to make any definitive conclusions, but a mosaic pattern of trait frequencies also suggests admixture. The recent modern human sample shows that while increased variation and a mosaic of non-metric traits persist through many generations after admixture has ceased, traditional methods of distance analysis cannot detect low levels of admixture within 200 years. The program structure is effective in finding patterns of variation within and among populations using morphological data. It will be useful for future analyses of dental traits and other fossil data, given the ability to use it with an incomplete data set.

Kansas City southern railway twenty-first century planning. Master's thesis, 7 August 1998--4 June 1999  

Science Conference Proceedings (OSTI)

Rail yards serve as major nodes that facilitate delivery of cargo to the consignee. The level of operational efficiency maintained within rail yards determines whether customers receive cargo late. Various external and internal factors can impede the operational efficiency of rail yards. The future growth of rail industry depends on how well it manages a potentially serious problem inherent to all railroads--rail congestion. This study reviews the processes that occur within the Knoche rail yard, which is located in Kansas City, Kansas. In an effort to improve the operational efficiency of the Knoche rail yard or to minimize congestion, the study will reveal the results of analyzing varying strategies to improve the operational efficiency of a single event, the rip track facility, within the Knoche rail yard. This study reveals that the operational efficiency of the Knoche rail yard may be enhanced if the following occur: (1) increase the rip track facility queue population from fifteen to twenty-two, and (2) spot bad order cars directly onto the two tracks leading into the rip track facility. Finally, the amount of double handling by switch engines daily may be decreased by as much as 96% within the rail yard.

Is It Time to Tailor the Prediction of Radio-Induced Toxicity in Prostate Cancer Patients? Building the First Set of Nomograms for Late Rectal Syndrome  

Science Conference Proceedings (OSTI)

Purpose: Development of user-friendly tools for the prediction of single-patient probability of late rectal toxicity after conformal radiotherapy for prostate cancer. Methods and Materials: This multicenter protocol was characterized by the prospective evaluation of rectal toxicity through self-assessed questionnaires (minimum follow-up, 36 months) by 718 adult men in the AIROPROS 0102 trial. Doses were between 70 and 80 Gy. Nomograms were created based on multivariable logistic regression analysis. Three endpoints were considered: G2 to G3 late rectal bleeding (52/718 events), G3 late rectal bleeding (24/718 events), and G2 to G3 late fecal incontinence (LINC, 19/718 events). Results: Inputs for the nomogram for G2 to G3 late rectal bleeding estimation were as follows: presence of abdominal surgery before RT, percentage volume of rectum receiving >75 Gy (V75Gy), and nomogram-based estimation of the probability of G2 to G3 acute gastrointestinal toxicity (continuous variable, which was estimated using a previously published nomogram). G3 late rectal bleeding estimation was based on abdominal surgery before RT, V75Gy, and NOMACU. Prediction of G2 to G3 late fecal incontinence was based on abdominal surgery before RT, presence of hemorrhoids, use of antihypertensive medications (protective factor), and percentage volume of rectum receiving >40 Gy. Conclusions: We developed and internally validated the first set of nomograms available in the literature for the prediction of radio-induced toxicity in prostate cancer patients. Calculations included dosimetric as well as clinical variables to help radiation oncologists predict late rectal morbidity, thus introducing the possibility of RT plan corrections to better tailor treatment to the patient's characteristics, to avoid unnecessary worsening of quality of life, and to provide support to the patient in selecting the best therapeutic approach.

A re-assembly and reconstruction of the 9th-century AD vessel wrecked off the coast of Bozburun, Turkey  

E-Print Network (OSTI)

In 1973, researchers from the Institute of Nautical Archaeology (INA) were led to the site of a wrecked ship by sponge diver Mehmet A??k??n, near his hometown of Bozburun, Turkey. During further monitoring over the following 21 years by INA, the site was identified as a merchant vessel dating from the 9th century AD. The excavation of the site by INA researchers and students from Texas A&M University occurred over four summer seasons, from 1995 to 1998, and yielded approximately 900 whole or nearly-whole amphorae, personal items, palynological material, and approximately 35 percent of the vessel??s wooden hull. This dissertation is a record of the curation, cataloging, analysis and re-assembly of the preserved elements of the Bozburun vessel??s hull, as well as a theoretical reconstruction of the entire vessel. The Bozburun vessel is unique as it is the only fully-excavated shipwreck from the 9th century AD, and is, indeed, a valuable source of examples of ship construction in the Mediterranean between the 7th and the 11th centuries AD. This dissertation, after discussing the methods of excavation and cataloging methods, posits the hypothesis that the techniques used to build this vessel represent a transitional stage in shipbuilding technology, combining distinctly old and new techniques. While the builders used embedded edge joinery in the ship??s planking, a very old method, they also appear to have used a conceptual framework and standards to design the vessel as well; methods evident in modified forms in Italian shipbuilding treatises from the Renaissance.

Preparing for climate change: major changes in global climate are virtually certain by the mid-21st century; researchers are beginning to explore ways we can adapt  

SciTech Connect

Major changes in the global climate are virtually certain by the mid-21st century due to the carbon dioxide and other greenhouse gases. Researchers are beginning to explore ways we can adopt. Scientist have long known that human activities, particularly the burning of fossil fuels, are artificially increasing the volume of greenhouse gases in the earth's atmosphere. This increase will eventually make the planet the hottest it has been in history. What remains controversial about the greenhouse effect is the rate of this global warming, its regional distribution, and most of all, what to do about the problem.

Archimedean-type force in a cosmic dark fluid. I. Exact solutions for the late-time accelerated expansion  

SciTech Connect

We establish a new self-consistent model in order to explain from a unified viewpoint two key features of the cosmological evolution: the inflation in the early Universe and the late-time accelerated expansion. The key element of this new model is the Archimedean-type coupling of the dark matter with dark energy, which form the so-called cosmic dark fluid. We suppose that dark matter particles immersed into the dark energy reservoir are affected by the force proportional to the four-gradient of the dark energy pressure. The Archimedean-type coupling is shown to play a role of effective energy-momentum redistributor between the dark matter and the dark energy components of the dark fluid, thus providing the Universe evolution to be a quasiperiodic and/or multistage process. In the first part of the work we discuss a theoretical base and new exact solutions of the model master equations. Special attention is focused on the exact solutions, for which the scale factor is presented by the anti-Gaussian function: these solutions describe the late-time acceleration and are characterized by a nonsingular behavior in the early Universe. The second part contains qualitative and numerical analysis of the master equations; we focus there on the solutions describing a multi-inflationary Universe.

Early and late time VLT spectroscopy of SN 2001el - progenitor constraints for a type Ia supernova  

E-Print Network (OSTI)

We present early time high-resolution (VLT/UVES) and late time low-resolution (VLT/FORS) optical spectra of the normal type Ia supernova, SN 2001el. The high-resolution spectra were obtained 9 and 2 days before (B-band) maximum light in order to detect narrow hydrogen and/or helium emission lines from the SN CSM. No such lines were detected in our data. We therefore use photoionisation models to derive upper limits of 1x10^-5 and 6x10^-5 Msol/yr, assuming wind velocities of 10 and 50 km/s, respectively, for the mass loss rate from the progenitor system of SN 2001el. This excludes a symbiotic star in the upper mass loss rate regime from being the progenitor of SN 2001el. The low-resolution spectrum was obtained in the nebular phase of the supernova, \\~400 days after the maximum light, to search for any hydrogen rich gas originating from the SN progenitor system. However, we see no signs of Balmer lines in our spectrum. Therefore, we model the late time spectra to derive an upper limit of ~0.03 Msol for solar a...

First accelerator mass spectrometry {sup 14}C dates documenting contemporaneity of nonanalog species in late Pleistocene mammal communities  

Science Conference Proceedings (OSTI)

Worldwide late Pleistocene terrestrial mammal faunas are characterized by stratigraphic associations of species that now have exclusive geographic ranges. These have been interpreted as either taphonomically mixed or representative of communities that no longer exist. Accelerator mass spectrometry {sup 14}C dates (n = 60) on single bones of stratigraphically associated fossil micromammals from two American and two Russian sites document for the first time that currently allopatric mammals occurred together between 12,000 and 22,000 yr B.P. on two continents. The existence of mammal communities without modern analogs demonstrates that Northern Hemisphere biological communities are ephemeral and that many modern biomes are younger than 12 ka. Future climate change may result in new nonanalog communities.

GRB 090926A AND BRIGHT LATE-TIME FERMI LARGE AREA TELESCOPE GAMMA-RAY BURST AFTERGLOWS  

SciTech Connect

GRB 090926A was detected by both the Gamma-ray Burst Monitor and Large Area Telescope (LAT) instruments on board the Fermi Gamma-ray Space Telescope. Swift follow-up observations began {approx}13 hr after the initial trigger. The optical afterglow was detected for nearly 23 days post trigger, placing it in the long-lived category. The afterglow is of particular interest due to its brightness at late times, as well as the presence of optical flares at T0+10{sup 5} s and later, which may indicate late-time central engine activity. The LAT has detected a total of 16 gamma-ray bursts; nine of these bursts, including GRB 090926A, also have been observed by Swift. Of the nine Swift-observed LAT bursts, six were detected by UVOT, with five of the bursts having bright, long-lived optical afterglows. In comparison, Swift has been operating for five years and has detected nearly 500 bursts, but has only seen {approx}30% of bursts with optical afterglows that live longer than 10{sup 5} s. We have calculated the predicted gamma-ray fluence, as would have been seen by the Burst Alert Telescope (BAT) on board Swift, of the LAT bursts to determine whether this high percentage of long-lived optical afterglows is unique, when compared to BAT-triggered bursts. We find that, with the exception of the short burst GRB 090510A, the predicted BAT fluences indicate that the LAT bursts are more energetic than 88% of all Swift bursts and also have brighter than average X-ray and optical afterglows.

Sequence stratigraphy of the late Pleistocene - Holocene deposits on the northwestern margin of the South Caspian Basin  

E-Print Network (OSTI)

Interpretation of 900 km of a closely spaced grid of high-resolution seismic profiles over the northwestern margin of South Caspian Basin (SCB) allows recognition and study of six late Pleistocene - Holocene depositional sequences. Sequence stratigraphy analysis of sedimentary strata from 117,000 years B.P. to present led to the identification of a highstand systems tract, two transgressive systems tracts and six lowstand systems tracts. Each systems tract is characterized by specific seismic facies. Diverse depositional processes on the northwestern margin of the SCB are suggested by the thirteen seismic facies patterns recognized in the study area. Two distinct progradational complexes were interpreted within Sequence III and Sequences IV and V in the northeastern and northwestern parts of the study area, respectively. Stratigraphic interpretation of the sequences provided important information on parameters that control depositional architectures, such as lake level fluctuations, tectonic dynamics, and sediment supply. High sedimentation rates combined with a series of high-frequency and high-amplitude lake-level fluctuations, abrupt changes at the shelf edge, abnormally high formation pressure, and high tectonic activity during Quaternary time resulted in the development of a variety of complex geologic drilling hazards. I distinguished three types of hazards as a result of this study: mud volcanoes, sediment instability, and shallow gas. The 2D high-resolution seismic dataset from the northwestern margin of the SCB allowed more detailed seismic sequence stratigraphic analysis in the study area than has previously been attempted. In particular, it has a clear application in deciphering sediment supply and relative lake level changes as well as tectonic relationship of the northwestern shelf margin of the SCB. Results of this work led us towards better understanding of recent depositional history, improved our knowledge of the nature of the basin tectonics, climate history and styles of and controls on sedimentation processes within a sequence stratigraphic framework during the late Pleistocene-Holocene time.

Do Intermediate Radiation Doses Contribute to Late Rectal Toxicity? An Analysis of Data From Radiation Therapy Oncology Group Protocol 94-06  

SciTech Connect

Purpose: To investigate whether the volumes of rectum exposed to intermediate doses, from 30 to 50 Gy, contribute to the risk of Grade {>=}2 late rectal toxicity among patients with prostate cancer receiving radiotherapy. Methods and Materials: Data from 1009 patients treated on Radiation Therapy Oncology Group protocol 94-06 were analyzed using three approaches. First, the contribution of intermediate doses to a previously published fit of the Lyman-Kutcher-Burman (LKB) normal tissue complication probability (NTCP) model was determined. Next, the extent to which intermediate doses provide additional risk information, after taking the LKB model into account, was investigated. Third, the proportion of rectum receiving doses higher than a threshold, VDose, was computed for doses ranging from 5 to 85 Gy, and a multivariate Cox proportional hazards model was used to determine which of these parameters were significantly associated with time to Grade {>=}2 late rectal toxicity. Results: Doses <60 Gy had no detectable impact on the fit of the LKB model, as expected on the basis of the small estimate of the volume parameter (n = 0.077). Furthermore, there was no detectable difference in late rectal toxicity among cohorts with similar risk estimates from the LKB model but with different volumes of rectum exposed to intermediate doses. The multivariate Cox proportional hazards model selected V75 as the only value of VDose significantly associated with late rectal toxicity. Conclusions: There is no evidence from these data that intermediate doses influence the risk of Grade {>=}2 late rectal toxicity. Instead, the critical doses for this endpoint seem to be {>=}75 Gy. It is hypothesized that cases of Grade {>=}2 late rectal toxicity occurring among patients with V75 less than approximately 12% may be due to a 'background' level of risk, likely due mainly to biological factors.

THE APPLICATION OF A STATISTICAL DOWNSCALING PROCESS TO DERIVE 21{sup ST} CENTURY RIVER FLOW PREDICTIONS USING A GLOBAL CLIMATE SIMULATION  

SciTech Connect

The ability of water managers to maintain adequate supplies in coming decades depends, in part, on future weather conditions, as climate change has the potential to alter river flows from their current values, possibly rendering them unable to meet demand. Reliable climate projections are therefore critical to predicting the future water supply for the United States. These projections cannot be provided solely by global climate models (GCMs), however, as their resolution is too coarse to resolve the small-scale climate changes that can affect hydrology, and hence water supply, at regional to local scales. A process is needed to ‘downscale’ the GCM results to the smaller scales and feed this into a surface hydrology model to help determine the ability of rivers to provide adequate flow to meet future needs. We apply a statistical downscaling to GCM projections of precipitation and temperature through the use of a scaling method. This technique involves the correction of the cumulative distribution functions (CDFs) of the GCM-derived temperature and precipitation results for the 20{sup th} century, and the application of the same correction to 21{sup st} century GCM projections. This is done for three meteorological stations located within the Coosa River basin in northern Georgia, and is used to calculate future river flow statistics for the upper Coosa River. Results are compared to the historical Coosa River flow upstream from Georgia Power Company’s Hammond coal-fired power plant and to flows calculated with the original, unscaled GCM results to determine the impact of potential changes in meteorology on future flows.

Early and late time VLT spectroscopy of SN 2001el - progenitor constraints for a type Ia supernova  

E-Print Network (OSTI)

We present early time high-resolution (VLT/UVES) and late time low-resolution (VLT/FORS) optical spectra of the normal type Ia supernova, SN 2001el. The high-resolution spectra were obtained at -9 and -2 days to allow the detection of narrow hydrogen and/or helium emission lines from the circumstellar medium of the SN. No such lines were detected, and we therefore use photoionisation models to derive upper limits of 9x10^-6 Msun/yr and 5x10^-5 Msun/yr for the mass loss rate from the progenitor system assuming velocities of 10 km/s and 50 km/s, respectively, for a wind extending to outside at least a few x 10^15 cm away from the SN explosion site. These limits exclude a symbiotic star in the upper mass loss rate regime from being the progenitor of SN 2001el. The low resolution spectrum was obtained in the nebular phase of the SN, 400 days after the maximum light, to search for any hydrogen rich gas originating from the SN progenitor system. However, we see no signs of Balmer lines in our spectrum. Therefore, we model the late time spectra to derive an upper limit of ~0.03 Msun for solar abundance material present at velocities lower than 1000 km/s within the SN explosion site. According to simulations of Marietta et al. (2000) this is less than the expected mass lost by a subgiant, red giant or main sequence secondary star at a small binary separation as a result of the SN explosion. Finally, we discuss the origin of high velocity Ca II lines. We see both the CaII IR triplet and the H&K lines in the -9 days spectrum at a very high velocity of up to 34000 km/s. The spectrum also shows a flat-bottomed Si II `6150 A' feature similar to the one previously observed in SN 1990N at -14 days. We compare these spectral features to those observed in SNe 1984A and 1990N at even higher velocities.

Late Wash/Nitric Acid flowsheet hydrogen generation bases for simulation of a deflagration/detonation in the DWPF CPC  

DOE Green Energy (OSTI)

Hydrogen generation data obtained from IDMS runs PX4 and PX5 will be used to determine a bases for a deflagration/detonation simulation in the DWPF CPC. This simulation is necessary due to the new chemistry associated with the Late Wash/ Nitric Acid flowsheet and process modifications associated with the presence of H{sub 2} in the offgas. The simulation will be performed by Professor Van Brunt from the University of South Carolina. The scenario which leads up to the deflagration/detonation simulation will be chosen such that the following conditions apply. The SRAT is filled to its maximum operating level with 9,600 gal of sludge, which corresponds to the minimum vapor space above the sludge. The SRAT is at the boiling point, producing H{sub 2} at a very low rate (about 10 % of the peak) and 15 scfm of air inleakage is entering the SRAT. Then, the H{sub 2} generation rate will be allowed to increase exponentially (catalyst activation) until it readies the peak H{sub 2} generation rate of the IDMS run, after which the H{sub 2} generation rate will be allowed to decay exponentially (catalyst deactivation) until the total amount of H2 produced is between 85 and 100% of that produced during the IDMS run.

WASP-10b: a 3M_J, gas-giant planet transiting a late-type K star  

E-Print Network (OSTI)

We report the discovery of WASP-10b, a new transiting extrasolar planet (ESP) discovered by the WASP Consortium and confirmed using NOT FIES and SOPHIE radial velocity data. A 3.09 day period, 29 mmag transit depth, and 2.36 hour duration are derived for WASP-10b using WASP and high precision photometric observations. Simultaneous fitting to the photometric and radial velocity data using a Markov-chain Monte Carlo procedure leads to a planet radius of 1.28R_J, a mass of 2.96M_J and eccentricity of ~0.06. WASP-10b is one of the more massive transiting ESPs, and we compare its characteristics to the current sample of transiting ESP, where there is currently little information for masses greater than ~2M_J and non-zero eccentricities. WASP-10's host star, GSC 2752-00114 (USNO-B1.0 1214-0586164) is among the fainter stars in the WASP sample, with V=12.7 and a spectral type of K5. This result shows promise for future late-type dwarf star surveys.

ASYMMETRIC TRANSIT CURVES AS INDICATION OF ORBITAL OBLIQUITY: CLUES FROM THE LATE-TYPE DWARF COMPANION IN KOI-13  

SciTech Connect

KOI-13.01, a planet-sized companion in an optical double star, was announced as one of the 1235 Kepler planet candidates in 2011 February. The transit curves show significant distortion that was stable over the {approx}130 days time span of the data. Here we investigate the phenomenon via detailed analyses of the two components of the double star and a re-reduction of the Kepler data with pixel-level photometry. Our results indicate that KOI-13 is a common proper motion binary, with two rapidly rotating components (vsin i {approx} 65-70 km s{sup -1}). We identify the host star of KOI-13.01 and conclude that the transit curve asymmetry is consistent with a companion orbiting a rapidly rotating, possibly elongated star on an oblique orbit. The radius of the transiter is 2.2 R{sub J} , implying an irradiated late-type dwarf, probably a hot brown dwarf rather than a planet. KOI-13 is the first example for detecting orbital obliquity for a substellar companion without measuring the Rossiter-McLaughlin effect with spectroscopy.

MELCOR 1.8.2 assessment: The MP-1 and MP-2 late phase melt progression experiments  

SciTech Connect

MELCOR is a fully integrated, engineering-level computer code being developed at Sandia National Laboratories for the USNRC, that models the entire spectrum of severe accident phenomena in a unified framework for both BWRs and PWRs. As a part of an ongoing assessment program, MELCOR has been used to model the MP-1 and MP-2 experiments, which provided data for late-phase melt progression in PWR geometries. Core temperature predicted by MELCOR were within 250--500 K of measured data in both MP-1 and MP-2. Relocation in the debris bed and metallic crust regions of MP-2 was predicted accurately compared to PIE data. Temperature gradients in lower portions of the test bundle were not predicted well in both MP-1 and MP-2, due to the lack of modeling of the heat transfer path to the cooling jacket in those portions of the test bundles. Fifteen sensitivity studies were run on various core (COR), control volume hydrodynamics (CVH) and heat structures (HS) package parameters. No unexpected sensitivities were found, and in particular there were no sensitivities to reduced time step, finer nodalization or to computer platform. Calculations performed by the DEBRIS and TAC2D codes for MP-1 and MP-2 showed better agreement with measured data than those performed by MELCOR. This was expected, through, due to the fully 2-dimensional modeling used in the other codes.

Ecological persistence in the Late Mississippian (Serpukhovian, Namurian A) Megafloral record of the Upper Silesian Basin, Czech Republic  

SciTech Connect

The Serpukhovian (Namurian A) stratigraphy of the Ostrava Formation, Upper Silesian Coal Basin, Czech Republic, consists of coal-bearing paralic sediments underlain by marine deposits in a cyclothemic nature similar to those in the Pennsylvanian of Euramerica. The thickness of the formation exceeds 3000 m, in which >170 coals are identified in a foreland basin setting. Fifty-five genetic cycles are identified in the present study, using transgressional erosional surfaces as lower and upper boundaries. Terrestrial plant-macrofossil assemblages are preserved within each cycle, mostly associated with coals, and these represent a sampling of the coastal plain vegetation. New high-precision isotope dilution-thermal ionization mass spectrometry U-Pb ages on zircons from tonsteins of two coals provide chronometric constraints for the Serpukhovian. Unweighted Pair Group Method with Arithmetic Mean clustering and Bayesian statistical classification group macrofloral assemblages into four distinct stratigraphic clusters, with assemblages persisting for <18 cycles before compositional change. Cycle duration, based on Ludmila (328.84{+-}0.16 Ma) and Karel (328.01{+-}0.08 Ma) tonsteins, overlaps the short-period (100 kyr) eccentricity cycle at the 95% confidence interval. These dates push the beginning of the Serpukhovian several million years deeper in time. An estimate for the Visean-Serpukhovian boundary is proposed at similar to 330 Ma. Late Mississippian wetland ecosystems persisted for >1.8 million years before regional perturbation, extirpation, or extinction of taxa occurred. Significant changes in the composition of macrofloral clusters occur across major marine intervals.

Sequence stratigraphic controls of hydrocarbon reservoir architecture - case study of Late Permian (Guadalupian) Queen Formation, Means Field, Andrews County, Texas.  

E-Print Network (OSTI)

The late Permian Queen Formation (115 m thick) is a succession of mixed clastics, carbonates and evaporites deposited in the northeastern margin of Central Basin Platform of the Permian Basin, west Texas, USA. Depositional facies, stacking patterns of cyclic facies associations and statistical correlation of rock property variations define geologic controls on reservoir rock properties. Textural, compositional, petrophysical and diagenetic variations within lithofacies exhibit systematic changes with stratigraphic position, which can be related to base level changes that were controlled by high-frequency, low-amplitude, sea level fluctuations during a greenhouse period. Ten lithofacies record variations in clastic input, shallow marine carbonate production, and evaporate precipitation in sabhkas and salinas. Four different types of lithofacies associations define: (1) transgressive deltaic deposits; (2) upward-shallowing evaporite and carbonate tidal-flat deposits; (3) transgressive beach ridge and sand flat deposits; and (4) upward-shallowing evaporite salina-sabhka deposits. Stacking patterns of lithofacies associations define sixteen depositional cycles that can be grouped into eight cycle sets. Cycle sets in turn are grouped to define two high-frequency sequences. Sequence 1 progresses from fluvial to carbonate tidal flat cycles. Sequence 2 consists of salina-dominated upward-shoaling cycles. Lateral continuity of cycles indicates restricted sedimentation on low-accommodation inner platform areas updip of prograding highstand platform-margin carbonate buildups, and a long-term trend of accommodation decrease. The Queen Formation contains two reservoir types; (1) siliciclastic reservoirs capped by evaporites and (2) layer-cake carbonate reservoirs. Of the four reservoir zones identified, R11 in lowstand fluvial-deltaic deposits has relatively little cement and the best reservoir characters.

A KNOWLEDGE DISCOVERY STRATEGY FOR RELATING SEA SURFACE TEMPERATURES TO FREQUENCIES OF TROPICAL STORMS AND GENERATING PREDICTIONS OF HURRICANES UNDER 21ST-CENTURY GLOBAL WARMING SCENARIOS  

Science Conference Proceedings (OSTI)

The connections among greenhouse-gas emissions scenarios, global warming, and frequencies of hurricanes or tropical cyclones are among the least understood in climate science but among the most fiercely debated in the context of adaptation decisions or mitigation policies. Here we show that a knowledge discovery strategy, which leverages observations and climate model simulations, offers the promise of developing credible projections of tropical cyclones based on sea surface temperatures (SST) in a warming environment. While this study motivates the development of new methodologies in statistics and data mining, the ability to solve challenging climate science problems with innovative combinations of traditional and state-of-the-art methods is demonstrated. Here we develop new insights, albeit in a proof-of-concept sense, on the relationship between sea surface temperatures and hurricane frequencies, and generate the most likely projections with uncertainty bounds for storm counts in the 21st-century warming environment based in turn on the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios. Our preliminary insights point to the benefits that can be achieved for climate science and impacts analysis, as well as adaptation and mitigation policies, by a solution strategy that remains tailored to the climate domain and complements physics-based climate model simulations with a combination of existing and new computational and data science approaches.

A peptide inhibitor of exportin1 blocks shuttling of the adenoviral E1B 55 kDa protein but not export of viral late mRNAs  

Science Conference Proceedings (OSTI)

The human subgroup C adenoviral E1B 55 kDa and E4 Orf6 proteins are required for efficient nuclear export of viral late mRNAs, but the cellular pathway that mediates such export has not been identified. As a first step to develop a general approach to address this issue, we have assessed the utility of cell-permeable peptide inhibitors of cellular export receptors. As both E1B and E4 proteins have been reported to contain a leucine-rich nuclear export signal (NES), we synthesized a cell-permeable peptide containing such an NES. This peptide induced substantial inhibition of export of the E1B protein, whereas a control, non-functional peptide did not. However, under the same conditions, the NES peptide had no effect on export of viral late mRNAs. These observations establish that viral late mRNAs are not exported by exportin1, as well as the value of peptide inhibitors in investigation of mRNA export regulation in adenovirus-infected cells.

Late Pleistocene to Recent sediment transport pathways of the Green Canyon OCS area, northern Gulf of Mexico  

E-Print Network (OSTI)

This study addresses some of the complexities of sediment transport systems on the continental slope of the Green Canyon OCS area south of the Louisiana coast. Five Late Pleistocene to Recent sedimentary sequences are identified using a combination of seismic and well data. Sediments are transported through pathways characterized by erosional surfaces and numerous channels which form as sediments remobilize and become transported downslope. Pathway margins are constricted by physiographic highs. Several processes are identified as means of carrying fine-grained sediments to and across the continental slope. The most important of these are mass movements (slumps and slides), debris flows, and turbidity currents. Faulting and/or slumping at the shelf edge remobilizes sediments which are then carried further downslope. These remobilized sediments may be transported as debris flows or other undifferentiated high-density flows, or may develop into turbidity currents which deposit graded sediments in response to decreases in slope gradient. Slumps and slides off salt uplifts also deposit large volumes of sediments into adjacent intraslope basins and sediment transport pathways, where they may contribute significant amounts of material to the downslope transport of sediments. Discrete channels are not often observed in the pathways due to multiple episodes of channel formation and erosion which occurred during a single sea level lowstand. These multiple episodes tend to remove or obscure prominent channel features. Sedimentation is cyclic. During one sea level lowstand a sequence is deposited in and along narrow pathways which successively fill intraslope basins from the shelf edge downslope. As each basin is filled, sediments spill over and continue downslope to a lower basin. Sedimentation during the next sea level lowstand occurs in broader pathways. Less sediments are deposited in the intraslope basin areas because they remain filled from the previous sequence. By the time of deposition of the next sequence, movement of underlying salt sheets has changed the shape of the pathway. The sedimentation pattern repeats as lower depressions fill and sediments spill over. Pathways transport slope sediments in the Green canyon area. Discrete channels are not often observed in the pathways. This is a result of two mechanisms: 1) multiple episodes of erosion during a sea level lowstand tend to remove or obscure prominent channel features, and 2) most sediments deposited within the pathways are mass transport deposits which do not often become channelized. The pathways are characterized by erosional surfaces and numerous conduits which form as sediments remobilize and become transported downslope. They are laterally relatively persistent, being constricted by structural highs,

XMM-Newton observations of the late-stage merger-remnant galaxies NGC 3921 and NGC 7252  

E-Print Network (OSTI)

Using the high sensitivity of XMM, we have studied the X-ray emission of the two proto-typical late-stage merger remnants, NGC 3921 and NGC 7252. In the case of NGC 7252, this is complemented by archival Chandra data. We investigate the nature of the discrete X-ray point source populations and the hot diffuse gas components in these two galaxies, and compare them in the light of their different merger ages and histories. We detect 3 candidate ultra-luminous X-ray point sources in NGC 3921 and at least 6 in NGC 7252, for which we have high spatial resolution Chandra data. These have luminosities ranging from \\~1.4x10^39-10^40 erg s^-1 (for H_0= 75 km s-1 Mpc^-1). We expect these ULXs to be high mass X-ray binaries, associated with the recent star formation in these two galaxies. Extended hot gas is observed in both galaxies. We have sufficient counts in the XMM data to fit two-component hot plasma models to their X-ray spectra and estimate the X-ray luminosities of the hot diffuse gas components to be 2.75x10^40 erg s^-1 and 2.09x10^40 erg s^-1 in NGC 3921 and NGC 7252, respectively. These luminosities are low compared with the luminosities observed in typical mature elliptical galaxies LX ~10^(41-42) erg s^-1), into which these merger remnants are expected to evolve. We do not see evidence that the X-ray halos of these galaxies are currently being regenerated to the masses and luminosities seen in typical elliptical galaxies. The mass of atomic gas available to fall back into the main bodies of these galaxies and shock-heat to X-ray temperatures is insufficient for this to be the sole halo regeneration mechanism. We conclude that halo regeneration is most likely a long-term (>10 Gyr) process, occurring predominantly via mass loss from evolving stars, in a sub-sonic outflow stage commencing ~2 Gyr after the merging event.

Geology and potential uses of the geopressure resources of the Gulf Coast. [6,000 MW-centuries of recoverable electric energy, 200 Tcf of methane  

DOE Green Energy (OSTI)

The US ERDA has supported efforts to evaluate the potential contribution to the national energy supply of geopressured geothermal resources in the Gulf Coast. Efforts include a program of resource assessment and programs to examine utilization of the resource for the production of electricity and as a source of industrial-process heat. Work on resource assessment has suggested the presence of perhaps as much as 6,000 MW-centuries of recoverable electric energy and of 200 Tcf of methane. This program has emphasized finding significantly large sand bodies within the geopressured stratigraphic section in addition to defining the distribution of abnormal fluid pressures and formation temperatures. Regional sand facies analyses conducted thus far indicate five locations in the Frio formation of Central and South Texas where adequately large geopressured geothermal resources may be present. Engineering studies of energy-conversion systems based on total-flow, flashed-steam, and binary-cycle concepts show that development of electric power from the Gulf Coast geopressure resource is technically feasible. Study of use of the resource as process heat in pulp and paper mills and new sugar refineries has shown that these uses also are technically sound. The thermal content of a barrel of geothermal brine can cost as little as 9 mills when credited for recoverable hydraulic energy and methane. The value of heat approaches 50 mills per bbl for certain applications. All programs have pointed out clearly the need for better specific understanding of the resource, especially its dissolved methane content and its ability to produce for tens of years.
