Red herrings and rotten fish  

E-Print Network (OSTI)

A longstanding problem in biology has been the origin of pervasive quarter-power allometric scaling laws that relate many characteristics of organisms to body mass (M) across the entire spectrum of life from molecules and microbes to ecosystems and mammals. In particular, whole-organism metabolic rate, B=aM^b, where a is a taxon-dependent normalisation constant and b is approximately equal to 3/4 for both animals and plants. Recently Darveau et al. (hereafter referred to as DSAH) proposed a "multiple-causes model" for B as "the sum of multiple contributors to metabolism", B_i, which were assumed to scale as M^(b_i). They obtained for average values of b: 0.78 for the basal rate and 0.86 for the maximally active rate. In this note we show that DSAH contains serious technical, theoretical and conceptual errors, including misrepresentations of published data and of our previous work. We also show that, within experimental error, there is no empirical evidence for an increase in b during aerobic activity as sugge...

Effect of Dead Algae on Soil Permeability  

SciTech Connect

Since existing basins support heavy growths of unicellular green algae which may be killed by temperature variation or by inadvertent pH changes in waste and then deposited on the basin floor, information on the effects of dead algae on soil permeability was needed. This study was designed to show the effects of successive algal kills on the permeability of laboratory soil columns.

The hydrodynamics of dead radio galaxies  

E-Print Network (OSTI)

We present a numerical investigation of dead, or relic, radio galaxies and the environmental impact that radio galaxy activity has on the host galaxy or galaxy cluster. We perform axisymmetric hydrodynamical calculations of light, supersonic, back-to-back jets propagating in a beta-model galaxy/cluster atmosphere. We then shut down the jet activity and let the resulting structure evolve passively. The dead source undergoes an initial phase of pressure driven expansion until it achieves pressure equilibrium with its surroundings. Thereafter, buoyancy forces drive the evolution and lead to the formation of two oppositely directed plumes that float high into the galaxy/cluster atmosphere. These plumes entrain a significant amount of low entropy material from the galaxy/cluster core and lift it high into the atmosphere. An important result is that a large fraction (at least half) of the energy injected by the jet activity is thermalized in the ISM/ICM core. The whole ISM/ICM atmosphere inflates in order to regain hydrostatic equilibrium. This inflation is mediated by an approximately spherical disturbance which propagates into the atmosphere at the sound speed. The fact that such a large fraction of the injected energy is thermalized suggests that radio galaxies may have an important role in the overall energy budget of rich ISM/ICM atmospheres. In particular, they may act as a strong and highly time-dependent source of negative feedback for galaxy/cluster cooling flows.

Dead-time compensation for a logarithmic display rate meter  

DOE Patents (OSTI)

An improved circuit is provided for application to a radiation survey meter that uses a detector that is subject to dead time. The circuit compensates for dead time over a wide range of count rates by producing a dead-time pulse for each detected event, a live-time pulse that spans the interval between dead-time pulses, and circuits that average the value of these pulses over time. The logarithm of each of these values is obtained and the logarithms are subtracted to provide a signal that is proportional to a count rate that is corrected for the effects of dead time. The circuit produces a meter indication and is also capable of producing an audible indication of detected events.

Dead Zones in LX-17 and PBX 9502  

Science Conference Proceedings (OSTI)

Pin and X-ray corner-turning data have been taken on ambient LX-17 and PBX 9052, and the results are listed in tables as an aid to future modeling. The results have been modeled at 4 zones/mm with a reactive flow approach that varies the burn rate as a function of pressure. A single rate format is used to simulate failure and detonation in different pressure regimes. A pressure cut-off must also be reached to initiate the burn. Corner-turning and failure are modeled using an intermediate pressure rate region, and detonation occurs at high pressure. The TATB booster is also modeled using reactive flow, and X-ray tomography is used to partition the ram-pressed hemisphere into five different density regions. The model reasonably fits the bare corner-turning experiment but predicts a smaller dead zone with steel confinement, in contradiction with experiment. The same model also calculates the confined and unconfined cylinder detonation velocities and predicts the failure of the unconfined cylinder at 3.75 mm radius. The PBX 9502 shows a smaller dead zone than LX-17. An old experiment that showed a large apparent dead zone in Comp B was repeated with X-ray transmission and no dead zone was seen. This confirms the idea that a variable burn rate is the key to modeling. The model also produces initiation delays, which are shorter than those found in time-to-detonation.

Why sequence microbial communities in expanding dead zones?  

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

microbial communities in expanding dead zones? microbial communities in expanding dead zones? Oxygen minimum zones (OMZs) are widespread oceanographic features expanding due to global warming. There is increasing evidence that ocean warming trends will decrease dissolved oxygen concentrations, causing hypoxic boundary layer expansion that impacts the global carbon cycle, marine nutrient cycles and the climate system. To properly diagnose these transitions, this project launches a systems-level investigation of microbial community responses to OMZ expansion, charting the gene expression patterns of indigenous microbial communities found in coastal and open ocean OMZs in the eastern Subarctic Pacific Ocean as part of an ongoing time series program monitoring microbial community responses to changing levels of water column oxygen deficiency.

Physical and chemical characterization of Dead Sea mud  

SciTech Connect

A laboratory analysis was performed to determine the physical and chemical properties of 24 Dead Sea mud samples collected from three different locations on the eastern shore of the Dead Sea. Several analytical techniques were used to determine the chemical and mineralogical compositions of those samples including atomic absorption spectrometry and X-ray diffraction. Physical parameters such as specific gravity, Atterberg limits, grain size, specific surface area, cation exchange capacity, pH and electrical conductivity were also studied. The main focus of the work was to document mud characteristics and to study the interrelation between physical and chemical properties. The mud samples were quite rich in minerals. Strontium was the most abundant trace element in the samples (range: 410-810 ppm) followed by barium (range: 155-380 ppm), vanadium (range: 209-264 ppm) and lead (range: 108-114 ppm). There were significant differences in the elemental contents of mud samples collected from different locations.

Deadly Carcinogen Unraveled: The Molecular Origami of Fungal Polyketide  

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

Deadly Carcinogen Unraveled: The Molecular Origami Deadly Carcinogen Unraveled: The Molecular Origami of Fungal Polyketide Aflatoxin is an unavoidable food contaminant in grains and nuts produced in developing countries. Chronic ingestion of nuts and grains contaminated with aflatoxin-producing molds such as Aspergillus parasiticus leads to a high rate of liver cancer, and is a large problem in developing countries. Aflatoxins belong to a class of natural products called polyketides, which are biosynthesized in many bacteria and fungi (1,2). Polyketide natural products produced by bacteria and fungi are often characterized by the presence of multiple aromatic rings that are responsible for the activity of polyketides as antibiotic, anticancer, and toxic compounds (2). Polyketide ring formation by fungal PKSs results from regiospecific cyclizations of reactive poly-beta-keto intermediates of specific length that is mediated by the product template (PT) domain (Fig. 1). The mechanism for aromatic ring formation, where a linear intermediate is transformed into a multicyclic product with high fidelity, has remained unclear. To reveal the cyclization mechanism, the Tsai lab at the University of California, Irvine, in collaboration with the Townsend lab at The Johns Hopkins University, solved the structure of the isolated PT domain of PksA to 1.8 Å using data from the SSRL beamline 9.1 and ALS beamline 8.2.2. The work was reported in the Oct 22 issue of Nature.

THE ROLE OF DEAD WOOD IN MAINTAINING ARTHROPOD DIVERSITY ON THE FOREST FLOOR.  

Science Conference Proceedings (OSTI)

AbstractDead wood is a major component of forests and contributes to overall diversity, primarily by supporting insects that feed directly on or in it. Further, a variety of organisms benefit by feeding on those insects. What is not well known is how or whether dead wood influences the composition of the arthropod community that is not solely dependent on it as a food resource, or whether woody debris influences prey available to generalist predators. One group likely to be affected by dead wood is ground-dwelling arthropods. We studied the effect of adding large dead wood to unburned and frequently burned pine stands to determine if dead wood was used more when the litter and understory plant community are removed. We also studied the effect of annual removal of dead wood from large (10-ha) plots over a 5-year period on ground-dwelling arthropods. In related studies, we examined the relationships among an endangered woodpecker that forages for prey on live trees, its prey, and dead wood in the forest. The results of these and other studies show that dead wood can influence the abundance and diversity of the ground-dwelling arthropod community and of prey available to generalist predators not foraging directly on dead trees.

Metagenome of a Versatile Chemolithoautotroph from Expanding Oceanic Dead Zones  

SciTech Connect

Oxygen minimum zones (OMZs), also known as oceanic"dead zones", are widespread oceanographic features currently expanding due to global warming and coastal eutrophication. Although inhospitable to metazoan life, OMZs support a thriving but cryptic microbiota whose combined metabolic activity is intimately connected to nutrient and trace gas cycling within the global ocean. Here we report time-resolved metagenomic analyses of a ubiquitous and abundant but uncultivated OMZ microbe (SUP05) closely related to chemoautotrophic gill symbionts of deep-sea clams and mussels. The SUP05 metagenome harbors a versatile repertoire of genes mediating autotrophic carbon assimilation, sulfur-oxidation and nitrate respiration responsive to a wide range of water column redox states. Thus, SUP05 plays integral roles in shaping nutrient and energy flow within oxygen-deficient oceanic waters via carbon sequestration, sulfide detoxification and biological nitrogen loss with important implications for marine productivity and atmospheric greenhouse control.

The Btu tax is dead, long live the Btu tax  

SciTech Connect

The energy industry is powerful. That is the only explanation for its ability to jettison a cornerstone of the Clinton Administration's proposed deficit reduction package, the Btu tax plan, expected to raise about $71.5 billion over a five-year period. Clinton had proposed a broad-based energy tax of 25.7 cents per million Btus, and a surcharge of 34.2 cents on petroleum products, to be phased in over three years starting July 1, 1994. House Democrats went along, agreeing to impose a tax of 26.8 cents per million Btus, along with the 34.2-cent petroleum surcharge, both effective July 1, 1994. But something happened on the way to the Senate. Their version of the deficit reduction package contains no broad-based energy tax. It does, however, include a 4.3 cents/gallon fuel tax. Clinton had backed down, and House Democrats were left feeling abandoned and angry. What happened has as much to do with politics-particularly the fourth branch of government, lobbyists-as with a President who wants to try to please everyone. It turns out that almost every lawmaker or lobbyist who sought an exemption from the Btu tax, in areas as diverse as farming or ship and jet fuel used in international commercial transportation, managed to get it without giving up much in return. In the end, the Btu tax was so riddled with exemptions that its effectiveness as a revenue-raiser was in doubt. Meanwhile, it turns out that the Btu tax is not dead. According to Budget Director Leon Panetta, the Administration has not given up on the Btu tax and will fight for it when the reconciliation bill goes to a joint House-Senate conference.

A grateful dead analysis: the relationship between concert and listening behavior  

Science Conference Proceedings (OSTI)

The Grateful Dead was an American band born out of the 1960s San Francisco, California psychedelic movement, that played music together from 1965 to 1995. Despite relatively little popular radio airtime, while on tour the Grateful Dead enjoyed a cult-like following from a fan base that numbered in the millions. Still today, some ten years after dissolution, the band remains popular according to online music services, such as last.fm. This article presents a comparative analysis between 1,590 of the Grateful Dead's live concert set lists from 1972 to 1995 and 2,616,990 Grateful Dead listening events by last.fm users from August 2005 to October 2007. While there is a strong correlation between how songs were played in concert and how they were listened to by last.fm members, the outlying songs in this trend identify interesting aspects of the band and their present-day fans.

Relationships between dead wood and arthropods in the Southeastern United States.  

SciTech Connect

The importance of dead wood to maintaining forest diversity is now widely recognized. However, the habitat associations and sensitivities of many species associated with dead wood remain unknown, making it difficult to develop conservation plans for managed forests. The purpose of this research, conducted on the upper coastal plain of South Carolina, was to better understand the relationships between dead wood and arthropods in the southeastern United States. In a comparison of forest types, more beetle species emerged from logs collected in upland pine-dominated stands than in bottomland hardwood forests. This difference was most pronounced for Quercus nigra L., a species of tree uncommon in upland forests. In a comparison of wood postures, more beetle species emerged from logs than from snags, but a number of species appear to be dependent on snags including several canopy specialists. In a study of saproxylic beetle succession, species richness peaked within the first year of death and declined steadily thereafter. However, a number of species appear to be dependent on highly decayed logs, underscoring the importance of protecting wood at all stages of decay. In a study comparing litter-dwelling arthropod abundance at different distances from dead wood, arthropods were more abundant near dead wood than away from it. In another study, grounddwelling arthropods and saproxylic beetles were little affected by large-scale manipulations of dead wood in upland pine-dominated forests, possibly due to the suitability of the forests surrounding the plots.

Security of high speed quantum key distribution with finite detector dead time  

E-Print Network (OSTI)

The security of a high speed quantum key distribution system with finite detector dead time \\tau is analyzed. When the transmission rate becomes higher than the maximum count rate of the individual detectors (1/\\tau ), security issues affect the algorithm for sifting bits. Analytical calculations and numerical simulations of the Bennett-Brassard BB84 protocol are performed. We study Rogers et al.'s protocol (introduced in "Detector dead-time effects and paralyzability in high-speed quantum key distribution," New J. Phys. 9 (2007) 319) in the presence of an active eavesdropper Eve who has the power to perform an intercept-resend attack. It is shown that Rogers et al.'s protocol is no longer secure. More specifically, Eve can induce a basis-dependent detection efficiency at the receiver's end. Modified key sifting schemes that are secure in the presence of dead time and an active eavesdropper are then introduced. We analyze and compare these secure sifting schemes for this active Eve scenario, and calculate and simulate their key generation rate. It is shown that the maximum key generation rate is 1/(2\\tau ) for passive basis selection, and 1/\\tau for active basis selection. The security analysis for finite detector dead time is also extended to the decoy state BB84 protocol.

Online Robot Dead Reckoning Localization Using Maximum Relative Entropy Optimization With Model Constraints  

SciTech Connect

The principle of Maximum relative Entropy optimization was analyzed for dead reckoning localization of a rigid body when observation data of two attached accelerometers was collected. Model constraints were derived from the relationships between the sensors. The experiment's results confirmed that accelerometers each axis' noise can be successfully filtered utilizing dependency between channels and the dependency between time series data. Dependency between channels was used for a priori calculation, and a posteriori distribution was derived utilizing dependency between time series data. There was revisited data of autocalibration experiment by removing the initial assumption that instantaneous rotation axis of a rigid body was known. Performance results confirmed that such an approach could be used for online dead reckoning localization.

Structure of the Yeast DEAD Box Protein Mss116p Reveals Two Wedges that Crimp RNA  

Science Conference Proceedings (OSTI)

The yeast DEAD box protein Mss116p is a general RNA chaperone that functions in mitochondrial group I and II intron splicing, translational activation, and RNA end processing. Here we determined high-resolution X-ray crystal structures of Mss116p complexed with an RNA oligonucleotide and ATP analogs AMP-PNP, ADP-BeF{sub 3}, or ADP-AlF{sub 4}{sup -}. The structures show the entire helicase core acting together with a functionally important C-terminal extension. In all structures, the helicase core is in a closed conformation with a wedge {alpha} helix bending RNA 3' of the central bound nucleotides, as in previous DEAD box protein structures. Notably, Mss116p's C-terminal extension also bends RNA 5' of the central nucleotides, resulting in RNA crimping. Despite reported functional differences, we observe few structural changes in ternary complexes with different ATP analogs. The structures constrain models of DEAD box protein function and reveal a strand separation mechanism in which a protein uses two wedges to act as a molecular crimper.

DEAD ZONES AS THERMAL BARRIERS TO RAPID PLANETARY MIGRATION IN PROTOPLANETARY DISKS  

Science Conference Proceedings (OSTI)

Planetary migration in standard models of gaseous protoplanetary disks is known to be very rapid ({approx}10{sup 5} years), jeopardizing the existence of planetary systems. We present a new mechanism for significantly slowing rapid planetary migration, discovered by means of radiative transfer calculations of the thermal structure of protoplanetary disks irradiated by their central stars. Rapid dust settling in a disk's dead zone-a region with very little turbulence-leaves a dusty wall at its outer edge. We show that the back-heating of the dead zone by this irradiated wall produces a positive gradient of the disk temperature, which acts as a thermal barrier to planetary migration which persists for the disk lifetime. Although we analyze in detail the migration of a super-Earth in a low-mass disk around an M star, our findings can apply to a wide variety of young planetary systems. We compare our findings with other potentially important stopping mechanisms and show that there are large parameter spaces for which dead zones are likely to play the most important role for reproducing the observed mass-period relation in longer planetary periods.

Analysis of the Isolated SecA DEAD Motor Suggests a Mechanism for Chemical?Mechanical Coupling  

SciTech Connect

The preprotein cross-linking domain and C-terminal domains of Escherichia coli SecA were removed to create a minimal DEAD motor, SecA-DM. SecA-DM hydrolyzes ATP and has the same affinity for ADP as full-length SecA. The crystal structure of SecA-DM in complex with ADP was solved and shows the DEAD motor in a closed conformation. Comparison with the structure of the E. coli DEAD motor in an open conformation (Protein Data Bank ID 2FSI) indicates main-chain conformational changes in two critical sequences corresponding to Motif III and Motif V of the DEAD helicase family. The structures that the Motif III and Motif V sequences adopt in the DEAD motor open conformation are incompatible with the closed conformation. Therefore, when the DEAD motor makes the transition from open to closed, Motif III and Motif V are forced to change their conformations, which likely functions to regulate passage through the transition state for ATP hydrolysis. The transition state for ATP hydrolysis for the SecA DEAD motor was modeled based on the conformation of the Vasa helicase in complex with adenylyl imidodiphosphate and RNA (Protein Data Bank ID 2DB3). A mechanism for chemical-mechanical coupling emerges, where passage through the transition state for ATP hydrolysis is hindered by the conformational changes required in Motif III and Motif V, and may be promoted by binding interactions with the preprotein substrate and/or other translocase domains and subunits.

Evaluation of dead time and gain shift correction for a liquid scintillation spectrometer  

SciTech Connect

The Department of Nuclear Engineering at Texas A and M University purchased a new generation liquid scintillation spectrometer--the LKB-Wallac Spectral Model 1219 in 1986. The Model 1219 features an auto sample changer with a capacity for 300 samples, and energy range of 1 to 2000 keV beta subdivided into 1024 channels, a Ra-226 external quench-correction standard, automatic dead time correction, and LED display of the beta energy spectrum. Gain stabilization is based on the use of a precision pulsed light-emitting diode (LED). The instrument's circuitry monitors the pulse height of the light emitted by the LED and adjusted the system gain as necessary to keep the LED-induced pulses constant, thus compensating for gain shifts. This paper reports that a simple test was devised to evaluate this liquid scintillation spectrometer's dead time correction and gain stabilization features. At the same time, the effectiveness of the counting chamber shielding was also tested for a specific situation.

Growth responses of mature loblolly pine to dead wood.manipulations.  

SciTech Connect

Large-scale manipulations of dead wood in mature Pinus taeda L. stands in the southeastern United States included a major one-time input of logs (fivefold increase in log volume) created by felling trees onsite, annual removals of all dead wood above >10 cm in diameter and >60 cm in length, and a reference in which no manipulations took place. We returned over a decade later to determine how these treatments affected tree growth using increment cores. There were no significant differences in tree density, basal area or tree diameters among treatments at the time of sampling. Although tree growth was consistently higher in the log-input plots and lower in the removal plots, this was true even during the 5 year period before the experiment began. When growth data from this initial period were included in the model as a covariate, no differences in post-treatment tree growth were detected. It is possible that treatment effects will become apparent after more time has passed, however.

The Feynman-Y Statistic in Relation to Shift-Register Neutron Coincidence Counting: Precision and Dead Time  

SciTech Connect

The Feynman-Y statistic is a type of autocorrelation analysis. It is defined as the excess variance-to-mean ratio, Y = VMR - 1, of the number count distribution formed by sampling a pulse train using a series of non-overlapping gates. It is a measure of the degree of correlation present on the pulse train with Y = 0 for Poisson data. In the context of neutron coincidence counting we show that the same information can be obtained from the accidentals histogram acquired using the multiplicity shift-register method, which is currently the common autocorrelation technique applied in nuclear safeguards. In the case of multiplicity shift register analysis however, overlapping gates, either triggered by the incoming pulse stream or by a periodic clock, are used. The overlap introduces additional covariance but does not alter the expectation values. In this paper we discuss, for a particular data set, the relative merit of the Feynman and shift-register methods in terms of both precision and dead time correction. Traditionally the Feynman approach is applied with a relatively long gate width compared to the dieaway time. The main reason for this is so that the gate utilization factor can be taken as unity rather than being treated as a system parameter to be determined at characterization/calibration. But because the random trigger interval gate utilization factor is slow to saturate this procedure requires a gate width many times the effective 1/e dieaway time. In the traditional approach this limits the number of gates that can be fitted into a given assay duration. We empirically show that much shorter gates, similar in width to those used in traditional shift register analysis can be used. Because the way in which the correlated information present on the pulse train is extracted is different for the moments based method of Feynman and the various shift register based approaches, the dead time losses are manifested differently for these two approaches. The resulting estimates for the dead time corrected first and second order reduced factorial moments should be independent of the method however and this allows the respective dead time formalism to be checked. We discuss how to make dead time corrections in both the shift register and the Feynman approaches.

High-Throughput Genetic Identification of Functionally Important Regions of the Yeast DEAD-Box Protein Mss116p  

Science Conference Proceedings (OSTI)

The Saccharomyces cerevisiae DEAD-box protein Mss116p is a general RNA chaperone that functions in splicing mitochondrial group I and group II introns. Recent X-ray crystal structures of Mss116p in complex with ATP analogs and single-stranded RNA show that the helicase core induces a bend in the bound RNA, as in other DEAD-box proteins, while a C-terminal extension (CTE) induces a second bend, resulting in RNA crimping. Here, we illuminate these structures by using high-throughput genetic selections, unigenic evolution, and analyses of in vivo splicing activity to comprehensively identify functionally important regions and permissible amino acid substitutions throughout Mss116p. The functionally important regions include those containing conserved sequence motifs involved in ATP and RNA binding or interdomain interactions, as well as previously unidentified regions, including surface loops that may function in protein-protein interactions. The genetic selections recapitulate major features of the conserved helicase motifs seen in other DEAD-box proteins but also show surprising variations, including multiple novel variants of motif III (SAT). Patterns of amino acid substitutions indicate that the RNA bend induced by the helicase core depends on ionic and hydrogen-bonding interactions with the bound RNA; identify a subset of critically interacting residues; and indicate that the bend induced by the CTE results primarily from a steric block. Finally, we identified two conserved regions - one the previously noted post II region in the helicase core and the other in the CTE - that may help displace or sequester the opposite RNA strand during RNA unwinding.

A human gene (DDX10) encoding a putative DEAD-box RNA helicase at 11q22-q23  

Science Conference Proceedings (OSTI)

A human gene encoding a putative RNA helicase, designated DDX10, was identified 400 kb telomeric to the ataxia-telangiectasia gene at chromosome 11q22-q23. The predicted amino acid sequence shows very high similarity to a subgroup of DEAD-box RNA helicases involved in ribosome biogenesis. This novel gene encodes a 3.2-kb transcript in a variety of human tissues. A processed pseudogene of DDX10 was detected at chromosome 9q21-q22. We observed a rare trinucleotide repeat length polymorphism within the coding sequence of DDX10. 39 refs., 5 figs.

The requirement of the DEAD-box protein DDX24 for the packaging of human immunodeficiency virus type 1 RNA  

Science Conference Proceedings (OSTI)

RNA helicases play important roles in RNA metabolism. Human immunodeficiency virus type 1 (HIV-1) does not carry its own RNA helicase, the virus thus needs to exploit cellular RNA helicases to promote the replication of its RNA at various steps such as transcription, folding and transport. In this study, we report that knockdown of a DEAD-box protein named DDX24 inhibits the packaging of HIV-1 RNA and thus diminishes viral infectivity. The decreased viral RNA packaging as a result of DDX24-knockdown is observed only in the context of the Rev/RRE (Rev response element)-dependent but not the CTE (constitutive transport element)-mediated nuclear export of viral RNA, which is explained by the specific interaction of DDX24 with the Rev protein. We propose that DDX24 acts at the early phase of HIV-1 RNA metabolism prior to nuclear export and the consequence of this action extends to the viral RNA packaging stage during virus assembly.

Structural and Functional Analysis of the Interaction Between the Nucleoporin Nup214 and the DEAD-box Helicase Ddx19  

Science Conference Proceedings (OSTI)

Key steps in the export of mRNA from the nucleus to the cytoplasm are the transport through the nuclear pore complex (NPC) and the subsequent remodeling of messenger RNA-protein (mRNP) complexes that occurs at the cytoplasmic side of the NPC. Crucial for these events is the recruitment of the DEAD-box helicase Ddx19 to the cytoplasmic filaments of the NPC that is mediated by the nucleoporin Nup214. Here, we present the crystal structure of the Nup214 N-terminal domain in complex with Ddx19 in its ADP-bound state at 2.5 {angstrom} resolution. Strikingly, the interaction surfaces are not only evolutionarily conserved but also exhibit strongly opposing surface potentials, with the helicase surface being positively and the Nup214 surface being negatively charged. We speculate that the positively charged surface of the interacting ADP-helicase binds competitively to a segment of mRNA of a linearized mRNP, passing through the NPC on its way to the cytoplasm. As a result, the ADP-helicase would dissociate from Nup214 and replace a single bound protein from the mRNA. One cycle of protein replacement would be accompanied, cooperatively, by nucleotide exchange, ATP hydrolysis, release of the ADP-helicase from mRNA and its rebinding to Nup214. Repeat of these cycles would remove proteins from a mRNP, one at a time, akin to a ratchet mechanism for mRNA export.

Quantitative Changes in Hydrocarbons over Time in Fecal Pellets of Incisitermes minor May Predict Whether Colonies Are Alive or Dead  

E-Print Network (OSTI)

# The Author(s) 2010. This article is published with open access at Springerlink.com Abstract Hydrocarbon mixtures extracted from fecal pellets of drywood termites are species-specific and can be characterized to identify the termites responsible for damage, even when termites are no longer present or are unable to be recovered easily. In structures infested by drywood termites, it is common to find fecal pellets, but difficult to sample termites from the wood. When fecal pellets appear after remedial treatment of a structure, it is difficult to determine whether this indicates that termites in the structure are still alive and active or not. We examined the hydrocarbon composition of workers, alates, and soldiers of Incisitermes minor (Hagen) (family Kalotermitidae) and of fecal pellets of workers. Hydrocarbons were qualitatively similar among castes and pellets. Fecal pellets that were aged for periods of 0, 30, 90, and 365 days after collection were qualitatively similar across all time periods, however, the relative quantities of certain individual hydrocarbons changed over time, with 19 of the 73 hydrocarbon peaks relatively increasing or decreasing. When the sums of the positive and negative slopes of these 19 hydrocarbons were indexed, they produced a highly significant linear correlation (R 2 =0.89). Consequently, the quantitative differences of these hydrocarbons peaks can be used to determine the age of worker fecal pellets, and thus help determine whether the colony that produced them is alive or dead.

The BAT1 gene in the MHC encodes an evolutionarily conserved putative nuclear RNA helicase of the DEAD family  

Science Conference Proceedings (OSTI)

The BAT1 gene has previously been identified about 30 kb upstream from the tumor necrosis factor (TNF) locus and close to a NF{sub kb}-related gene of the nuclear factor family in the major histocompatibility complex (MHC) of human, mouse, and pig. We now show that the BAT1 translation product is the homolog of the rat p47 nuclear protein, the WM6 Drosophila gene product, and probably also Ce08102 of Caenorhabditis elegans, all members of the DEAD protein family of ATP-dependent RNA helicases. This family has more than 40 members, including the eukaryotic translation initiation factor-4A (eIF-4A), the human nuclear protein p68, and the Drosophila oocyte polar granule component vasa. BAT1 spans about 10 kb, is split into 10 exons of varying length, and encodes a protein of 428 amino acids ({approximately}48 kDa). Human and pig BAT1 cDNAs display 95.6% identity in the coding region and 80% identity in the 5{prime} and 3{prime} noncoding regions. Several repeat sequences of different types were identified in introns of the porcine BAT1 gene. Three different mRNAs, 4.1,1.7, and 0.9 kb, respectively, were detected in all tissues analyzed upon hybridization with porcine BAT1 cDNA. Transfection and expression of human BAT1 cDNA after tagging with a heterologous antibody recognition epitope revealed a nuclear localization of the hybrid protein. An MspI RFLP was detected in an SLA class I typed family, confirming the localization of the BAT1 gene in the porcine MHC. BAT1 thus encodes a putative nuclear ATP-dependent RNA helicase and is likely to have an indispensable function. 35 refs., 6 figs., 1 tab.

Do oil markets work; is OPEC dead  

SciTech Connect

In this paper the authors review what has happened in world oil markets since the 1970s and examine the prospects for OPEC and world oil prices. The paper summarizes the data for the last two decades: by fuel, by product, and by region. It focuses on OPEC and its members, examining the differences in behavior between its members and non-OPEC producers. The authors find that OPEC is clearly still relevant, if no longer very powerful. Its members have collectively reduced output dramatically, in an unsuccessful attempt to defend the price increases. They examine the important institutional changes of the last two decades, in comparison with the industry's stability for much of the century. They suggest an interpretation of OPEC's current situation. The paper summarizes the outlook for OPEC and the world oil market over the next two decades.

Specifically, until recently processors consisted of one copy of a CPU, the latter exploiting as much Instruction-Level Parallelism as possible. This improved performance. Unfortunately, two trends collided and caused a rapid shift in processor architecture: 1) The architecture community's ability to extract ILP from typical code asymptotically approached zero, so processor companies kept increasing the CPU clock rate to compensate and improve performance in a brute force way. Marketing also played a large role here: its relatively easy to sell processors based on a single [higher] number. 2) Processor temperatures

Distance Is Not Dead: Social Interaction and Geographical Distance in the Internet Era  

E-Print Network (OSTI)

The Internet revolution has made long-distance communication dramatically faster, easier, and cheaper than ever before. This, it has been argued, has decreased the importance of geographic proximity in social interactions, transforming our world into a global village with a borderless society. We argue for the opposite: while technology has undoubtedly increased the overall level of communication, this increase has been most pronounced for local social ties. We show that the volume of electronic communications is inversely proportional to geographic distance, following a Power Law. We directly study the importance of physical proximity in social interactions by analyzing the spatial dissemination of new baby names. Counter-intuitively, and in line with the above argument, the importance of geographic proximity has dramatically increased with the internet revolution.

Identification of the human DEAD-box protein p68 as a substrate of Tlk1  

Science Conference Proceedings (OSTI)

The activity of the human protein kinase Tlk1 is down-regulated within minutes after exposure of cells to ionizing radiation. In order to identify signaling pathways which might be relevant in the radiation response of mammalian cells we screened nuclear proteins for substrates of Tlk1. Among several proteins one could be identified as p68 RNA helicase. Furthermore, it could be shown that Tlk1 phosphorylates immunoprecipitated p68. The phosphorylation of the C-terminal fragment of p68 by rTlk1 reduced its affinity to single stranded RNA in a gel shift assay. In addition, it could be demonstrated that increasing the Tlk1 activity in HT1080 cells by forced Tlk1 overexpression leads to an increased phosphorylation of endogenous p68, arguing that p68 might be a physiological substrate of Tlk1. These findings open the possibility that Tlk1 might participate in diverse biologic functions like cell growth and differentiation, pre-mRNA splicing, and transcriptional coactivation.

Production of Millisecond Dips in Sco X-1 Count Rates by Dead Time Effects  

E-Print Network (OSTI)

Chang et al. (2006) reported millisecond duration dips in the X-ray intensity of Sco X-1 and attributed them to occultations of the source by small trans-Neptunian objects (TNOs). We have found multiple lines of evidence that these dips are not astronomical in origin, but rather the result of high-energy charged particle events in the RXTE PCA detectors. Our analysis of the RXTE data indicates that at most 10% of the observed dips in Sco X-1 could be due to occultations by TNOs, and, furthermore, we find no positive or supporting evidence for any of them being due to TNOs. We therefore believe that it is a mistake to conclude that any TNOs have been detected via occultation of Sco X-1.

AUTOMATED DEAD-END ULTRAFILTRATION FOR ENHANCED SURVEILLANCE OF LEGIONELLA 2 PNEUMOPHILA AND LEGIONELLA SPP. IN COOLING TOWER WATERS  

DOE Green Energy (OSTI)

Detection of Legionella pneumophila in cooling towers and domestic hot water systems involves concentration by centrifugation or membrane filtration prior to inoculation onto growth media or analysis using techniques such as PCR or immunoassays. The Portable Multi-use Automated Concentration System (PMACS) was designed for concentrating microorganisms from large volumes of water in the field and was assessed for enhancing surveillance of L. pneumophila at the Savannah River Site, SC. PMACS samples (100 L; n = 28) were collected from six towers between August 2010 and April 2011 with grab samples (500 ml; n = 56) being collected before and after each PMACS sample. All samples were analyzed for the presence of L. pneumophila by direct fluorescence immunoassay (DFA) using FITC-labeled monoclonal antibodies targeting serogroups 1, 2, 4 and 6. QPCR was utilized for detection of Legionella spp. in the same samples. Counts of L. pneumophila from DFA and of Legionella spp. from qPCR were normalized to cells/L tower water. Concentrations were similar between grab and PMACS samples collected throughout the study by DFA analysis (P = 0.4461; repeated measures ANOVA). The same trend was observed with qPCR. However, PMACS concentration proved advantageous over membrane filtration by providing larger volume, more representative samples of the cooling tower environment, which led to reduced variability among sampling events and increasing the probability of detection of low level targets. These data highlight the utility of the PMACS for enhanced surveillance of L. pneumophila by providing improved sampling of the cooling tower environment.

202-328-5000 www.rff.orgNight of the Living Dead or Back to the Future? Electric Utility Decoupling, Reviving Rate-of-Return Regulation, and Energy Efficiency  

E-Print Network (OSTI)

The distribution grid for delivering electricity to the user has been paid for as part of the charge per kilowatt-hour that covers the cost of the energy itself. Conservation advocates have promoted the adoption of policies that decouple electric distribution company revenues or profits from how much electricity goes through the lines. Their motivation is that usage-based pricing leads utilities to encourage use and discourages conservation. Because decoupling divorces profits from conduct, it runs against the dominant finding in regulatory economics in the last twenty yearsthat incentive-based regulation outperforms rate-of-return. Even if distribution costs are independent of use, some usage charges can be efficient. Price-cap regulation may distort utility incentives to inform consumers about energy efficiencygetting more performance from less electricity. Utilities will subsidize efficiency investments, but only when prices are too low. Justifying policies to subsidize energy efficiency requires either prices that are too low or consumers who are ignorant.

Liveness of Heap Data for Functional Programs  

E-Print Network (OSTI)

Functional programming languages use garbage collection for heap memory management. Ideally, garbage collectors should reclaim all objects that are dead at the time of garbage collection. An object is dead at an execution instant if it is not used in future. Garbage collectors collect only those dead objects that are not reachable from any program variable. This is because they are not able to distinguish between reachable objects that are dead and reachable objects that are live. In this paper, we describe a static analysis to discover reachable dead objects in programs written in first-order, eager functional programming languages. The results of this technique can be used to make reachable dead objects unreachable, thereby allowing garbage collectors to reclaim more dead objects.

I would like to know why food -- especially meat--smells bad when it goes bad. Also Why does bread grow mold and why is it green and blue? Thank you. Replies: Jason, When food is being eaten by bacteria, they produce byproducts just like we do. The compounds they produce cause the smell of rotten meat. There is a reason we don't like that smell: it warns us that that food is probably unsafe to eat. So biology has built in a safety rule: you would not normally eat something that you don't like the smell of. The molds on bread are a special kind that like bread. Their spores are everywhere but only when we leave our bread long enough can they grow to sufficient numbers so that we can see them. Again, you can smell the bread is off, you can see it, and if you hadn't noticed you will taste it. However you should not eat bread with molds on: they produce toxic substances. I don't think there is a reason for them to be green and blue, at least I don't know it.

Replies: Sammy: Do you mean does the animal itself feel like it is dead? Or do you mean does it feel dead to us when we touch it? The answer to both is, no. If you were to pick up a hibernating snake, for instance, it would feel cold, but it would not be stiff as it would be if dead, and if you handled it it would begin to stir. We really can't say how the animal itself feels, they are enough different from us that we can't know exactly how their brains sense their environment, especially in hibernation which is not like anything humans experience. J. Elliott I can't imagine what it would be like to "feel dead." More likely, they are unconscious or drowsy, possibly like a deep sleep.

Adaptive engine injection for emissions reduction  

DOE Patents (OSTI)

NOx and soot emissions from internal combustion engines, and in particular compression ignition (diesel) engines, are reduced by varying fuel injection timing, fuel injection pressure, and injected fuel volume between low and greater engine loads. At low loads, fuel is injected during one or more low-pressure injections occurring at low injection pressures between the start of the intake stroke and approximately 40 degrees before top dead center during the compression stroke. At higher loads, similar injections are used early in each combustion cycle, in addition to later injections which preferably occur between about 90 degrees before top dead center during the compression stroke, and about 90 degrees after top dead center during the expansion stroke (and which most preferably begin at or closely adjacent the end of the compression stroke). These later injections have higher injection pressure, and also lower injected fuel volume, than the earlier injections.

Internal combustion engine using premixed combustion of stratified charges  

DOE Patents (OSTI)

During a combustion cycle, a first stoichiometrically lean fuel charge is injected well prior to top dead center, preferably during the intake stroke. This first fuel charge is substantially mixed with the combustion chamber air during subsequent motion of the piston towards top dead center. A subsequent fuel charge is then injected prior to top dead center to create a stratified, locally richer mixture (but still leaner than stoichiometric) within the combustion chamber. The locally rich region within the combustion chamber has sufficient fuel density to autoignite, and its self-ignition serves to activate ignition for the lean mixture existing within the remainder of the combustion chamber. Because the mixture within the combustion chamber is overall premixed and relatively lean, NO.sub.x and soot production are significantly diminished.

Life history and habitat associations of the broad wood cockroach, Parcoblatta lata (Blattaria: Blattellidae) and other native cockroaches in the Coastal Plain of South Carolina.  

DOE Green Energy (OSTI)

Wood cockroaches are an important prey of the red-cockaded woodpecker, Picoides borealis, an endangered species inhabiting pine forests in the southern United States. These woodpeckers forage on the boles of live pine trees, but their prey consists of a high proportion of wood cockroaches, Parcoblatta spp., that are more commonly associated with dead plant material. Cockroach population density samples were conducted on live pine trees, dead snags and coarse woody debris on the ground. The studies showed that snags and logs are also important habitats of wood cockroaches in pine forests.

High-pressure liquid chromatographic gradient mixer  

DOE Patents (OSTI)

A gradient mixer effects the continuous mixing of any two miscible solvents without excessive decay or dispersion of the resultant isocratic effluent or of a linear or exponential gradient. The two solvents are fed under low or high pressure by means of two high performance liquid chromatographic pumps. The mixer comprises a series of ultra-low dead volume stainless steel tubes and low dead volume chambers. The two solvent streams impinge head-on at high fluxes. This initial nonhomogeneous mixture is then passed through a chamber packed with spirally-wound wires which cause turbulent mixing thereby homogenizing the mixture with minimum band-broadening.

CO{sub 2} flux measurements across portions of the Dixie Valley geothermal system, Nevada  

DOE Green Energy (OSTI)

A map of the CO{sub 2} flux across a newly formed area of plant kill in the NW part of the Dixie Valley geothermal system was constructed to monitor potential growth of a fumarole field. Flux measurements were recorded using a LI-COR infrared analyzer. Sample locations were restricted to areas within and near the dead zone. The data delineate two areas of high CO{sub 2} flux in different topographic settings. Older fumaroles along the Stillwater range front produce large volumes of CO{sub 2} at high temperatures. High CO{sub 2} flux values were also recorded at sites along a series of recently formed ground fractures at the base of the dead zone. The two areas are connected by a zone of partial plant kill and moderate flux on an alluvial fan. Results from this study indicate a close association between the range front fumaroles and the dead zone fractures. The goals of this study are to characterize recharge to the geothermal system, provide geochemical monitoring of reservoir fluids and to examine the temporal and spatial distribution of the CO{sub 2} flux in the dead zone. This paper reports the results of the initial CO{sub 2} flux measurements taken in October, 1997.

Gender and the homoerotic logic of torture at Abu Ghraib  

E-Print Network (OSTI)

The focus of this dissertation is a social and cultural theoretical analysis of the empirical data regarding the prison abuse that occurred at Abu Ghraib prison in Iraq by American forces. I provide the following: an examination of the photographs of abuse that were leaked to the press in the fall of 2003; an analysis of both Lynndie Englands and Sabrina Harmans courts-martial (two of the rotten apples); a discussion of the body associated with punishment and torture, and also as marked in ways of identification; and an assessment of additional representations regarding prisoner abuse at Abu Ghraib. Throughout this analysis, I use gender as a lens to understand Abu Ghraib and the subsequent courts-martial. It is important to note that I gained access to and was intimately involved as a graduate researcher for Dr. Stjepan G. Mestrovic, an expert for the defense, and experienced the events of the trials themselves, first-hand and during closed counsel and open session. The empirical data provided is drawn primarily from first-hand qualitative research that involved participant-observation of two trials, interaction with soldiers and officers, and analysis of both documents pertaining to the trial as well as the photographs of abuse themselves, among other things. I incorporate cultural studies, feminist and sociological theory (modern and postmodern), and feminist philosophy so as to provide a theoretical analysis of the abuse at Abu Ghraib and the subsequent courts-martial focused on gender and sexuality. The result of this dissertation is a social and cultural theoretical analysis of the empirical data regarding the prison abuse that occurred at Abu Ghraib prison in Iraq by American forces, where women, gender, and sexuality are shown to be important criteria for examination. Specifically, the results of this project highlight areas that current analyses of the abuse at Abu Ghraib have left out: how women fit into American military politics, how gender functions as power within the military, how gender is socially constructed in the military in terms of heterosexuality, and how both gender and sexuality are used as weapons by the American military. This kind of examination is useful in future policy considerations for the military and for detainee treatment, where analyses of women, gender, sexuality, and power have been so far neglected in any serious way, and even by sociologists Phillip Zimbardo and the application of his Stanford Prison Study to the events of Abu Ghraib.

October 22, 2009 October 22, 2009 Model Microbial Community for Studying Expanding Dead Zones Characterized WALNUT CREEK, CA-Among the many changes in the ocean is the expansion of oxygen-deficient or oxygen minimum zones (OMZs), also known as dead zones, which affect the processes by which carbon is captured and sequestered on the seafloor and alter the microbial activities that impact the rate and magnitude of ocean carbon sequestration. Despite the importance of these effects, very little is known about the metabolism of OMZ microbes and how they respond to environmental changes.

Variable displacement blower  

DOE Patents (OSTI)

A blower having a stationary casing for rotatably supporting a rotor assembly having a series of open ended chambers arranged to close against the surrounding walls of the casing. Pistons are slidably mounted within each chamber with the center of rotation of the pistons being offset in regard to the center of rotation of the rotor assembly whereby the pistons reciprocate in the chambers as the rotor assembly turns. As inlet port communicates with the rotor assembly to deliver a working substance into the chamber as the pistons approach a top dead center position in the chamber while an outlet port also communicates with the rotor to exhaust the working substance as the pistons approach a bottom dead center position. The displacement of the blower is varied by adjusting the amount of eccentricity between the center of rotation of the pistons and the center of rotation of the rotor assembly.

High rate 4. pi. beta. -. gamma. coincidence counting system  

SciTech Connect

A high count rate 4..pi.. ..beta..-..gamma.. coincidence counting system for the determination of absolute disintegration rates of short half-life radionuclides is described. With this system the dead time per pulse is minimized by not stretching any pulses beyond the width necessary to satisfy overlap coincidence requirements. The equations used to correct for the ..beta.., ..gamma.., and coincidence channel dead times and for accidental coincidences are presented but not rigorously developed. Experimental results are presented for a decaying source of /sup 56/Mn initially at 2 x 10/sup 6/ d/s and a set of /sup 60/Co sources of accurately known source strengths varying from 10/sup 3/ to 2 x 10/sup 6/ d/s. A check of the accidental coincidence equation for the case of two independent sources with varying source strengths is presented.

Biomass growth restriction in a packed bed reactor  

DOE Patents (OSTI)

When carrying out continuous biologically catalyzed reactions with anaerobic microorganisms attached to a support in an upflow packed bed column, growth of the microorganisms is restricted to prevent the microorganisms from plugging the column by limiting the availability of an essential nutrient and/or by the presence of predatory protozoa which consume the anaerobic microorganisms. A membrane disruptive detergent may be provided in the column to lyse dead microorganisms to make them available as nutrients for live microorganisms.

3D Technologies for Large Area Trackers  

E-Print Network (OSTI)

We describe technologies which can be developed to produce large area, low cost pixelated tracking detec- tors. These utilize wafer-scale 3D electronics and sensor technologies currently being developed in industry. This can result in fully active sensor/readout chip tiles which can be assembled into large area arrays with good yield and minimal dead area. The ability to connect though the bulk of the device can also provide better electrical performance and lower mass.

Extending operating range of a homogeneous charge compression ignition engine via cylinder deactivation  

DOE Patents (OSTI)

An HCCI engine has the ability to operate over a large load range by utilizing a lower cetane distillate diesel fuel to increase ignition delay. This permits more stable operation at high loads by avoidance of premature combustion before top dead center. During low load conditions, a portion of the engines cylinders are deactivated so that the remaining cylinders can operate at a pseudo higher load while the overall engine exhibits behavior typical of a relatively low load.

Trigger-disabling Acquisition System for Quantum Key Distribution failsafe against Self-blinding  

E-Print Network (OSTI)

Modern single-photon detectors based on avalanche photodiodes offer increasingly higher triggering speeds, thus fostering their use in several fields, prominently in the recent area of Quantum Key Distribution. To reduce the probability of an afterpulse, these detectors are usually equipped with a circuitry that disables the trigger for a certain time after a positive detection event, known as dead time. If the acquisition system connected to the detector is not properly designed, efficiency issues arise when the triggering rate is faster than the inverse of detector's dead-time. Moreover, when this happens with two or more detectors used in coincidence, a security risk called "self-blinding" can jeopardize the distribution of a secret quantum key. In this paper we introduce a trigger-disabling circuitry based on an FPGA-driven feedback loop, so to avoid the above-mentioned inconveniences. In the regime of single-photon-attenuated light, the electronics dynamically accept a trigger only after detectors' complete recovery from dead-time. This technique proves useful to work with detectors at their maximum speed and to increase the security of a quantum key distribution setup.

Three dimensional nuclear magnetic resonance spectroscopic imaging of sodium ions using stochastic excitation and oscillating gradients  

SciTech Connect

Nuclear magnetic resonance (NMR) spectroscopic imaging of {sup 23}Na holds promise as a non-invasive method of mapping Na{sup +} distributions, and for differentiating pools of Na{sup +} ions in biological tissues. However, due to NMR relaxation properties of {sup 23}Na in vivo, a large fraction of Na{sup +} is not visible with conventional NMR imaging methods. An alternate imaging method, based on stochastic excitation and oscillating gradients, has been developed which is well adapted to measuring nuclei with short T{sub 2}. Contemporary NMR imaging techniques have dead times of up to several hundred microseconds between excitation and sampling, comparable to the shortest in vivo {sup 23}Na T{sub 2} values, causing significant signal loss. An imaging strategy based on stochastic excitation has been developed which greatly reduces experiment dead time by reducing peak radiofrequency (RF) excitation power and using a novel RF circuit to speed probe recovery. Continuously oscillating gradients are used to eliminate transient eddy currents. Stochastic {sup 1}H and {sup 23}Na spectroscopic imaging experiments have been performed on a small animal system with dead times as low as 25{mu}s, permitting spectroscopic imaging with 100% visibility in vivo. As an additional benefit, the encoding time for a 32x32x32 spectroscopic image is under 30 seconds. The development and analysis of stochastic NMR imaging has been hampered by limitations of the existing phase demodulation reconstruction technique. Three dimensional imaging was impractical due to reconstruction time, and design and analysis of proposed experiments was limited by the mathematical intractability of the reconstruction method. A new reconstruction method for stochastic NMR based on Fourier interpolation has been formulated combining the advantage of a several hundredfold reduction in reconstruction time with a straightforward mathematical form.

Characteristics of Signals Originating near the Lithium-Diffused N+ Contact of High Purity Germanium P-Type Point Contact Detectors  

Science Conference Proceedings (OSTI)

A study of signals originating near the lithium-diffused n+ contact of p-type point contact (PPC) high purity germanium detectors (HPGe) is presented. The transition region between the active germanium and the fully dead layer of the n+ contact is examined. Energy depositions in this transition region are shown to result in partial charge collection. This provides a mechanism for events with a well defined energy to contribute to the continuum of the energy spectrum at lower energies. A novel technique to quantify the contribution from this source of background is introduced. Experiments that operate germanium detectors with a very low energy threshold may benefit from the methods presented herein.

On mathematical foundation of the Brownian motor theory  

E-Print Network (OSTI)

The paper contains mathematical justification of basic facts concerning the Brownian motor theory. The homogenization theorems are proved for the Brownian motion in periodic tubes with a constant drift. The study is based on an application of the Bloch decomposition. The effective drift and effective diffusivity are expressed in terms of the principal eigenvalue of the Bloch spectral problem on the cell of periodicity as well as in terms of the harmonic coordinate and the density of the invariant measure. We apply the formulas for the effective parameters to study the motion in periodic tubes with nearly separated dead zones.

Apparatus for closed-loop combustion control in internal combustion engines  

SciTech Connect

Schematically disclosed is an engine control apparatus wherein cylinder pressure is sensed before and after the top dead center position. Desired cylinder pressure curves are stored in a microcomputer for a range of engine speed-load combinations. By electrically comparing the actual pressure-time curve with the desired pressure curve for the existing speed-load combination it should be possible to generate an error signal representing deviation of actual engine performance from the desired performance, i.e., a permissible plus or minus band following the desired curve. The invention would provide a control action using only three parameters, namely engine speed, engine load and cylinder pressure.

Single-photon sources and detectors are key enabling technologies in quantum information processing. Nanowire-based superconducting single-photon detectors (SSPDs) offer single-photon detection from the visible well into the infrared with low dark counts, low jitter and short dead times. We report on the high fidelity characterization (via antibunching and spontaneous emission lifetime measurements) of a cavity-coupled single-photon source at 902 nm using a pair of SSPDs. The twin SSPD scheme reported here is well-suited to the characterization of single-photon sources at telecom wavelengths (1310 nm, 1550 nm).

Investment Busts, Reputation, and the Temptation to Blend in with the Crowd ?  

E-Print Network (OSTI)

We provide a real-options model of an industry in which agents time abandonment of their projects in an effort to protect their reputations. Agents delay abandonment attempting to signal their quality. When a public common shock forces abandonment of a small fraction of projects irrespective of agents quality, many agents abandon their projects strategically even if they are unaffected by the shock. Such blending in with the crowd effect creates an additional incentive to delay abandonment ahead of the shock, leading to accumulation of living dead projects, which further amplifies the shock. The potential for moderate public common shocks often improves agentsvalues.

Operators are trained to understand the functions of alarm management components, their use and response, and obtain feedback. Today the power station reports about one alarm per hour. 3 photos.

Fabrication of the GLAST Silicon Tracker Readout Electronics  

Science Conference Proceedings (OSTI)

A unique electronics system has been built and tested for reading signals from the silicon-strip detectors of the Gamma-ray Large Area Space Telescope mission. The system amplifies and processes signals from 884,736 36-cm long silicon strips in a 4 x 4 array of tower modules. An aggressive mechanical design fits the readout electronics in narrow spaces between the tower modules, to minimize dead area. This design and the resulting departures from conventional electronics packaging led to several fabrication challenges and lessons learned. This paper describes the fabrication processes and how the problems peculiar to this design were overcome.

Power control for heat engines  

DOE Patents (OSTI)

A power control arrangement for a Stirling engine includes a sleeve mounted in each cylinder for axial movement and a port in the sleeve leading to a dead space. The port is covered by the piston at a position that is determined by the piston position and the axial adjustment of the sleeve. The compression phase of the Stirling cycle for that piston begins when the port is covered, so the position of the sleeve is used to set the Stirling engine power level.

Microfluidic interconnects  

DOE Patents (OSTI)

A miniature connector for introducing microliter quantities of solutions into microfabricated fluidic devices. The fluidic connector, for example, joins standard high pressure liquid chromatography (HPLC) tubing to 1 mm diameter holes in silicon or glass, enabling ml-sized volumes of sample solutions to be merged with .mu.l-sized devices. The connector has many features, including ease of connect and disconnect; a small footprint which enables numerous connectors to be located in a small area; low dead volume; helium leak-tight; and tubing does not twist during connection. Thus the connector enables easy and effective change of microfluidic devices and introduction of different solutions in the devices.

Has radiation protection become a health hazard?  

SciTech Connect

Scientists and engineers have a responsibility to speak out when their findings and recommendations lead to public harm. This can happen in several ways. One is when the media misinterpret or sensationalize a scientific fact misleading the public and creating unwarranted fear. Another is when regulations or public policy decision are purportedly based on scientific data but are, in fact, scientifically invalid. Fear of radiation has been far more detrimental to health than radiation itself. The author knows of no deaths to the public from accidental release of radiation, but the consequences of fear have been deadly.

Endovascular Treatment of Blunt Traumatic Abdominal Aortic Occlusion With Kissing Stent Placement  

Science Conference Proceedings (OSTI)

Blunt traumatic abdominal aortic dissection is extremely rare and potentially deadly. We present the case of a 62-year-old man involved in a frontal car crash. After emergency undergoing laparotomy for bowel injuries, he was referred to our hospital due to acute ischemia of bilateral lower extremities on day 3 after the trauma. Computed tomography and aortography showed an aortobiiliac dissection with complete occlusion. This injury was successfully treated by endovascular treatment with 'kissing'-technique stent placement, which appears to be a safe, effective, and minimally invasive treatment.

Flu Terms Defined  

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

Flu Terms Defined Flu Terms Defined H1N1 Influenza is a respiratory disease of pigs caused by type A influenza viruses that causes regular outbreaks in pigs. People do not normally get H1N1 flu, but human infections can and do happen. H1N1 flu viruses have been reported to spread from person-to-person, but in the past, this transmission was limited and not sustained beyond three people. Avian flu (AI) is caused by influenza viruses that occur naturally among wild birds. Low pathogenic AI is common in birds and causes few problems. Highly pathogenic H5N1 is deadly to domestic fowl, can be transmitted from birds to humans, and is deadly to humans. There is virtually no human immunity and human vaccine availability is very limited. Pandemic flu is virulent human flu that causes a global outbreak, or pandemic, of serious illness. Because there is little natural immunity, the disease can spread easily from person to person. Currently, there is no pandemic flu.

Using Unmanned Helicopters to Assess Vegetation Cover in Sagebrush Steppe Ecosystems  

SciTech Connect

Evaluating vegetation cover is an important factor in understanding the sustainability of many ecosystems. Methods that have sufficient accuracy and improved cost efficiency could dramatically alter how biotic resources are monitored on both public and private lands. This will be of interest to land managers because there are rarely enough resource specialists or funds available for comprehensive ground evaluations. In this project, unmanned helicopters were used to collect still-frame imagery to assess vegetation cover during May, June, and July in 2005. The images were used to estimate percent cover for six vegetative cover classes (shrub, dead shrub, grass, forbs, litter, and bare ground). The field plots were located on the INL site west of Idaho Falls, Idaho. Ocular assessments of digital imagery were performed using a software program called SamplePoint, and the results were compared against field measurements collected using a point-frame method to assess accuracy. The helicopter imagery evaluation showed a high degree of agreement with field cover class values for litter, bare ground, and grass, and reasonable agreement for dead shrubs. Shrub cover was often overestimated and forbs were generally underestimated. The helicopter method took 45% less time than the field method to set plots and collect and analyze data. This study demonstrates that UAV technology provides a viable method for monitoring vegetative cover on rangelands in less time and with lower costs. Tradeoffs between cost and accuracy are critical management decisions that are important when managing vegetative conditions across vast sagebrush ecosystems throughout the Intermountain West.

Structural load combinations  

SciTech Connect

This paper presents the latest results of the program entitled, ''Probability Based Load Combinations For Design of Category I Structures''. In FY 85, a probability-based reliability analysis method has been developed to evaluate safety of shear wall structures. The shear walls are analyzed using stick models with beam elements and may be subjected to dead load, live load and in-plane eqrthquake. Both shear and flexure limit states are defined analytically. The limit state probabilities can be evaluated on the basis of these limit states. Utilizing the reliability analysis method mentioned above, load combinations for the design of shear wall structures have been established. The proposed design criteria are in the load and resistance factor design (LRFD) format. In this study, the resistance factors for shear and flexure and load factors for dead and live loads are preassigned, while the load factor for SSE is determined for a specified target limit state probability of 1.0 x 10/sup -6/ or 1.0 x 10/sup -5/ during a lifetime of 40 years. 23 refs., 9 tabs.

Delayed neutrons from the neutron irradiation of ?U  

E-Print Network (OSTI)

A series of experiments was performed with the Texas A&M University Nuclear Science Center Reactor (NSCR) to verify ?U delayed neutron emission rates. A custom device was created to accurately measure a sample's pneumatic flight time and the Nuclear Science Center's (NSC's) pneumatic transfer system (PTS) was redesigned to reduce a sample's pneumatic flight time from over 1,600 milliseconds to less than 450 milliseconds. Four saturation irradiations were performed at reactor powers of 100 and 200 kW for 300 seconds and one burst irradiation was performed using a $1.61 pulse producing 19.11 MW-s of energy. Experimental results agreed extremely well with those of Keepin. By comparing the first ten seconds of collected data, the first saturation irradiation deviated ~1.869% with a dead time of 2 microseconds, while the burst irradiation deviated ~0.303% with a dead time of 5 microseconds. Saturation irradiations one, three and four were normalized to the initial count rate of saturation irradiation two to determine the system reproducibility, and deviated ~0.449%, ~0.343% and ~0.389%, respectively.

Development of a reliability-analysis method for category I structures. [PWR; BWR  

DOE Green Energy (OSTI)

The present paper develops a reliability analysis method for category I nuclear structures, particularly for reinforced concrete containment structures subjected to various load combinations. The loads considered here include dead loads, accidental internal pressure and earthquake ground acceleration. For mathematical tractability, an earthquake occurrence is assumed to be governed by the Poisson arrival law, while its acceleration history is idealized as a Gaussian vector process of finite duration. A vector process consists of three component processes, each with zero mean. The second order statistics of this process are specified by a three-by-three spectral density matrix with a multiplying factor representing the overall intensity of the ground acceleration. With respect to accidental internal pressure, the following assumptions are made: (a) it occurs in accordance with the Poisson law; (b) its intensity and duration are random; and (c) its temporal rise and fall behaviors are such that a quasi-static structural analysis applies. A dead load is considered to be a deterministic constant.

Estimation of structural reliability under combined loads. [PWR; BWR  

DOE Green Energy (OSTI)

For the overall safety evaluation of seismic category I structures subjected to various load combinations, a quantitative measure of the structural reliability in terms of a limit state probability can be conveniently used. For this purpose, the reliability analysis method for dynamic loads, which has recently been developed by the authors, was combined with the existing standard reliability analysis procedure for static and quasi-static loads. The significant parameters that enter into the analysis are: the rate at which each load (dead load, accidental internal pressure, earthquake, etc.) will occur, its duration and intensity. All these parameters are basically random variables for most of the loads to be considered. For dynamic loads, the overall intensity is usually characterized not only by their dynamic components but also by their static components. The structure considered in the present paper is a reinforced concrete containment structure subjected to various static and dynamic loads such as dead loads, accidental pressure, earthquake acceleration, etc. Computations are performed to evaluate the limit state probabilities under each load combination separately and also under all possible combinations of such loads.

Method of energy load management using PCM for heating and cooling of buildings  

DOE Patents (OSTI)

A method is described for energy load management for the heating and cooling of a building. The method involves utilizing a wallboard as a portion of the building, the wallboard containing about 5 to about 30 wt.% phase change material such that melting of the phase change material occurs during a rise in temperature within the building to remove heat from the air, and a solidification of the phase change material occurs during a lowering of the temperature to dispense heat into the air. At the beginning of either of these cooling or heating cycles, the phase change material is preferably ``fully charged``. In preferred installations one type of wallboard is used on the interior surfaces of exterior walls, and another type as the surface on interior walls. The particular PCM is chosen for the desired wall and room temperature of these locations. In addition, load management is achieved by using PCM-containing wallboards that form cavities of the building such that the cavities can be used for the air handling duct and plenum system of the building. Enhanced load management is achieved by using a thermostat with reduced dead band of about the upper half of a normal dead band of over three degrees. In some applications, air circulation at a rate greater than normal convection provides additional comfort. 7 figs.

ABSTRACT The Deepwater Horizon Oil Spill Disaster: A Graphical Assessment of its Impact on  

E-Print Network (OSTI)

The Deepwater Horizon oil spill occurred in the Gulf of Mexico on April 20, 2010. Considered the largest accidental marine oil spill in history, oil flowed for three months and approximately five million barrels of oil spilled through by mid-July 2010. In this report, we analyse fish and bird data to assess the impact of the oil spill on the Gulf wildlife. Our findings based on the available fish data for 2005, 2006, and 2010 are not very helpful to make a judgement on the negative impact of the oil spill on fish species. On the other hand, the bird data analysis shows that the closer the surface oil spill area approached to bird habitats, the more dead birds were observed. The highest number of dead birds was observed in July and August when birds bred and raised their offspring. However, the migration behaviour of different bird species makes it impossible to entirely estimate the full impact of the oil spill on birds.

Response of "Alamo" switchgrass tissue chemistry and biomass to nitrogen fertilization in west Tennessee, USA  

SciTech Connect

Switchgrass (Panicum virgatum) is a perennial, warm-season grass that has been identified as a potential biofuel feedstock over a large part of North America.Weexamined above- and belowground responses to nitrogen fertilization in Alamo switchgrass grown in West Tennessee, USA. The fertilizer study included a spring and fall sampling of 5-year old switchgrass grown under annual applications of 0, 67, and 202 kgNha?1 (as ammonium nitrate). Fertilization changed switchgrass biomass allocation as indicated by root:shoot ratios. End-of-growing season root:shoot ratios (meanSE) declined significantly (P?0.05) at the highest fertilizer nitrogen treatment (2.160.08, 2.020.18, and 0.880.14, respectively, at 0, 67, and 202 kgNha?1). Fertilization also significantly increased above- and belowground nitrogen concentrations and decreased plant C:N ratios. Data are presented for coarse live roots, fine live roots, coarse dead roots, fine dead roots, and rhizomes. At the end of the growing season, there was more carbon and nitrogen stored in belowground biomass than aboveground biomass. Fertilization impacted switchgrass tissue chemistry and biomass

Trigger-disabling Acquisition System for Quantum Key Distribution failsafe against Self-blinding  

E-Print Network (OSTI)

Modern single-photon detectors based on avalanche photodiodes offer increasingly higher triggering speeds, thus fostering their use in several fields, prominently in the recent area of Quantum Key Distribution. To reduce the probability of an afterpulse, these detectors are usually equipped with a circuitry that disables the trigger for a certain time after a positive detection event, known as dead time. If the acquisition system connected to the detector is not properly designed, efficiency issues arise when the triggering rate is faster than the inverse of detector's dead-time. Moreover, when this happens with two or more detectors used in coincidence, a security risk called "self-blinding" can jeopardize the distribution of a secret quantum key. In this paper we introduce a trigger-disabling circuitry based on an FPGA-driven feedback loop, so to avoid the above-mentioned inconveniences. In the regime of single-photon-attenuated light, the electronics dynamically accept a trigger only after detectors' compl...

Response of breeding seaside sparrows to fire on the upper Texas Coast  

E-Print Network (OSTI)

Fire is one of the primary tools for managing coastal marshes in parts of the range of the Seaside Sparrow (Ammodramus maritimus). This study examined changes in Seaside Sparrow densities between breeding seasons following fire in marshes of the upper Texas coast. I measured habitat characteristics and relative abundances of Seaside Sparrows on two 250-m transects for three breeding seasons post-fire on one site, and four breeding seasons on two sites. The number of sparrows/survey the second year post-fire averaged 2.8 (2.2-3.2) times higher than any other year post-fire. Two sites had significantly more sparrows/survey in the second year post-fire than the first, third, or fourth. The third site had a significant increase in sparrows/survey from the first to second year after burning, but the third year was not different from the first or second year. The increase in sparrows/survey from the first to second year post-fire coincided with a significant increase in the cover of dead vegetation. Dead vegetation may be an important factor for suitable nesting conditions, at least in the second year after burning.

Modeling of the solids transportation within an industrial rotary dryer: A simple model  

SciTech Connect

To better understand the underlying phenomena taking place in an industrial rotary dryer and to determine the optimum operating conditions, a simulator in which the solids transportation, the gas flow, and the heat and mass transfer are modeled is currently being developed. This paper describes the use of interactive perfect mixers in series to model the solids transportation within an industrial rotary dryer, on the basis of an experimental residence time distribution curve (RTD). Two simple models are proposed: a series of perfect well-mixed interacting tanks and a modified Cholette-Cloutier model. The first model is not able to account for the nonideal behavior of the solids transportation in the rotary dryer. To account for the characteristic extended tail of the RTD curves observed in industrial dryers, in a second model, the solid phase is divided between an active and a dead zone. This model, with 36 cells and 25% of the volume occupied by the dead zones, modeled very well the industrial RTD curve. In addition, the model produces bed depth and axial velocity profiles that are consistent with those reported in the literature.

Jumpering of electric power transmission lines at a dead end tower. Two transmission line conductor bundles each contain five or more spaced apart subconductors (5) arranged in the shape of a cylinder having a circular cross section. The ends of each bundle of subconductors are attached with insulators to a dead end tower (1). Jumpering allows the electric current to flow between the two bundles of subconductors using jumper buses, internal jumper conductors, and external jumper conductors. One or more current collecting jumper buses (37) are located inside each bundle of subconductors with each jumper bus being attached to the end of a subconductor. Small-diameter internal jumper conductors (33) are located in the inherently electrically shielded area inside each bundle of subconductors with each subconductor (except ones having an attached jumper bus) having one internal jumper conductor connected between that subconductor's end and a jumper bus. Large-diameter external jumper conductors (9) are located outside each bundle of subconductors with one or more external jumper conductors being connected between the jumper buses in one bundle of subconductors and the jumper buses in the other bundle.

Seismic Analysis of Morrow Point Dam  

DOE Green Energy (OSTI)

The main objective of this study is to perform nonlinear dynamic earthquake time history analyses on Morrow Point Dam, which is located 263 km southwest of Denver, Colorado. This project poses many significant technical challenges, one of which is to model the entire Morrow Point Dam/Foundation Rock/Reservoir system which includes accurate geology topography. In addition, the computational model must be initialized to represent the existing dead loads on the structure and the stress field caused by the dead loads. To achieve the correct dead load stress field due to gravity and hydrostatic load, the computer model must account for the manner in which the dams were constructed. Construction of a dam finite element model with the correct as-built geometry of the dam structure and simply ''turning on'' gravity in the computer model will generally lead to an incorrect initial stress field in the structure. The sequence of segmented lifts typical of dam construction has a significant impact on the static stress fields induced in the dam. In addition, the dam model must also account for the interaction between the adjacent dam segments across the dam contraction joints. As a result of these challenges, it was determined that a significant amount of code development was required in order to accurately simulate the motion of the dam structure. Modifications to the existing slide surfaces are needed to allow for appropriate modeling of the shear keys across the contraction joints. Furthermore, a model for hydrodynamic interaction was also implemented into NIKE3D and DYNA3D for fluid representation in the 3D dam system finite element model. Finally, the modeling of the 3D dam system results in a very large computational model, which makes it difficult to perform a static initialization using an implicit code. Traditionally, for these large models, the model has been initialized over a long time scale using an explicit code. However, recent advancements have made it possible to run NIKE3D in ''parallel'' on relatively small parallel machines as well as on the ASCI platforms.

PROTOSTELLAR DISK EVOLUTION OVER MILLION-YEAR TIMESCALES WITH A PRESCRIPTION FOR MAGNETIZED TURBULENCE  

SciTech Connect

Magnetorotational instability (MRI) is the most promising mechanism behind accretion in low-mass protostellar disks. Here we present the first analysis of the global structure and evolution of non-ideal MRI-driven T-Tauri disks on million-year timescales. We accomplish this in a 1+1D simulation by calculating magnetic diffusivities and utilizing turbulence activity criteria to determine thermal structure and accretion rate without resorting to a three-dimensional magnetohydrodynamical (MHD) simulation. Our major findings are as follows. First, even for modest surface densities of just a few times the minimum-mass solar nebula, the dead zone encompasses the giant planet-forming region, preserving any compositional gradients. Second, the surface density of the active layer is nearly constant in time at roughly 10 g cm{sup -2}, which we use to derive a simple prescription for viscous heating in MRI-active disks for those who wish to avoid detailed MHD computations. Furthermore, unlike a standard disk with constant-{alpha} viscosity, the disk midplane does not cool off over time, though the surface cools as the star evolves along the Hayashi track. Instead, the MRI may pile material in the dead zone, causing it to heat up over time. The ice line is firmly in the terrestrial planet-forming region throughout disk evolution and can move either inward or outward with time, depending on whether pileups form near the star. Finally, steady-state mass transport is an extremely poor description of flow through an MRI-active disk, as we see both the turnaround in the accretion flow required by conservation of angular momentum and peaks in M-dot (R) bracketing each side of the dead zone. We caution that MRI activity is sensitive to many parameters, including stellar X-ray flux, grain size, gas/small grain mass ratio and magnetic field strength, and we have not performed an exhaustive parameter study here. Our 1+1D model also does not include azimuthal information, which prevents us from modeling the effects of Rossby waves.

Effects of overstory composition and prescribed fire on fuel loading across a heterogeneous managed landscape in the southeastern USA.  

Science Conference Proceedings (OSTI)

In the southeastern USA, land use history, forest management and natural geomorphic features have created heterogeneous fuel loads. This apparent temporal and spatial variation in fuel loads make it difficult to reliably assess potential fire behavior from remotely sensed canopy variables to determine risk and to prescribe treatments. We examined this variation by exploring the relationships between overstory forest vegetation attributes, recent fire history, and selected surface fuel components across an 80,000 ha contiguous landscape. Measurements of dead and live vegetation components of surface fuels were obtained from 624 permanent plots, or about 1 plot per 100 ha of forest cover. Within forest vegetation groups, we modeled the relationship between individual surface fuel components and overstory stand age, basal area, site quality and recent fire history, then stochastically predicted fuel loads across the landscape using the same linkage variables. The fraction of the plot variation, i.e., R2, explained by predictive models for individual fuel components ranged from 0.05 to 0.66 for dead fuels and 0.03 to 0.97 for live fuels in pine dominated vegetation groups. Stand age and basal area were generally more important than recent fire history for predicting fuel loads. Mapped fuel loads using these regressor variables showed a very heterogeneous landscape even at the scale of a few square kilometers. The mapped patterns corresponded to stand based forest management disturbances that are reflected in age, basal area, and fire history. Recent fire history was significant in explaining variation in litter and duff biomass. Stand basal area was positively and consistently related to dead fuel biomass in most groups and was present in many predictive equations. Patterns in live fuel biomass were related to recent fire history, but the patterns were not consistent among forest vegetation groups. Age and basal area were related to live fuels in a complex manner that is likely confounded with periodic disturbances that disrupt stand dynamics. This study complements earlier hazardous fuels research in the southeastern USA, and indicates that succession, disturbance, site quality and decomposition interact with forest management practices to create variable spatial and temporal conditions. The inclusion of additional land use, disturbance history, and soil-topographic variables coupled to improved sampling methods may increase precision and subsequent fuel mapping.

Rabies Infection  

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

Rabies Rabies is a deadly viral infection that is mainly spread by infected animals. Causes, incidence, and risk factors Rabies is spread by infected saliva that enters the body through a bite or broken skin. The virus travels from the wound to the brain, where it causes swelling, or inflammation. This inflammation leads to symptoms of the disease. Most rabies deaths occur in children. In the past, human cases in the United States usually resulted from a dog bite, but recently, more cases of human rabies have been linked to bats and raccoons. Although dog bites are a common cause of rabies in developing countries, there have been no reports of rabies caused by dog bites in the United States for a number of years due to widespread animal vaccination.

A Bird Flu Protein Link to Virulence A Bird Flu Protein Link to Virulence Smart viruses infect without killing the host, at least in the short term. In such low-level infections, the virus gains time to persist, reproduce, infect other individuals, and spread through the population. Some viruses persist in certain host populations without killing them, but in other hosts they have a rapid and deadly effect. The H5N1 virus strains responsible for recent lethal outbreaks of bird flu apparently existed for quite some time in wild goose populations without doing much harm. But when the same strains infected chickens, the results were disastrous, leading to high chicken mortality and a health risk for humans living in proximity. In fact, the risk of epidemic was considered high enough to lead China to

There was a time, especially in Germany, when foresters grew trees as farmers grow cabbages: thousands of acres covered with just one kind planted in long rows that were kept free of all seedlings, underbrush, dead or injured trees and everything but perfect specimens. For a while these plantations produced astonishing yields of lumber and the Germans boasted of them as models of "efficiency". The fact that they supported practically no wildlife -- only a few birds, no food for deer, and so forth -- was contemptuously dismissed.

Honey, nuts and berries are eaten also. Aside from the lynx, eagles, owls and the fisher, a marten's chief enemy is man.

Ancient trees found underwater may provide clues to climate change. Photo by Ben Raines/AL.com/AP An ancient grove of Cypress trees found 60 feet underwater may help scientists understand past climate change. Sonar data was used to find 50 and 100 stumps, as well as an unknown number of logs. The trees are closely related to the modern-day Bald Cypress. The forest itself has been dead at least 50,000 years, according to scientists at the Lawrence Livermore Laboratory, who dated samples from the trees by looking for carbon-14, a radioactive isotope that is found in every living organism but that steadily decays after the

Oak Wilt Oak Wilt Nature Bulletin No. 479-A February 3, 1973 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation OAK WILT Our sturdy oaks, symbols of strength, toughness and durability, are menaced by a deadly fungous disease called Oak Wilt, They are being attacked in at least 18 states from Minnesota and Kansas to Pennsylvania and North Carolina. That is alarming to those who recall that, during the first 35 years of this century, all but a few of our native chestnuts were annihilated by Chestnut Blight -- a fungus brought here in young chestnuts from Asia. Since 1930, we have lost untold numbers of fine elms and are desperately battling to save the rest from destruction by Dutch elm disease caused by a European fungus. Now the oaks, most important of all our hardwoods, are similarly threatened.

Why sequence thermophiles in Great Basin hot springs?  

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

thermophiles in Great Basin hot springs? thermophiles in Great Basin hot springs? A thermophile is an organism that thrives in extremely hot temperature conditions. These conditions are found in the Great Basin hot springs, where the organisms have been exposed to unique conditions which guide their lifecycle. High temperature environments often support large and diverse populations of microorganisms, which appear to be hot spots of biological innovation of carbon fixation. Sequencing these microbes that make their home in deadly heat could provide various insights into understanding energy production and carbon cycling. Converting cellulosic biomass to ethanol is one of the most promising strategies to reduce petroleum consumption in the near future. This can only be achieved by enhancing recovery of fermentable sugars from complex

Did U Know? Did U Know? Common U.S. agricultural products specifically grown for biofuel production include switchgrass and soybeans. Can you really drive a car off grass instead of gas? Yes! Switch grass is a common, warm-season grass that can be an environmentally friendly biofuel and alternative to traditional gasoline. How cool is that! Humans have used biomass fuels for heating and cooking since the discovery of fire. Biofuel is any liquid fuel derived from biological material such as trees, agricultural wastes, crops, or even grass. Biofuel can be produced from any carbon source that can be replenished rapidly, such as plants. Biomass refers to living and recently dead biological matter that can be used as fuel or for industrial production. Biofuel is considered a means of reducing greenhouse gas emissions

4 4 3.2.3.3 Additional Wildlife Observations In September, a dead crow (Corvus brachyrhynchos) was observed dangling from the top of a spruce tree at the Site. Closer inspection revealed there was fishing line wrapped around the foot of the bird. Evidently the crow picked up the fishing line on its foot at one of the nearby reservoirs (since fishing is not allowed at the Site). The line was probably dangling from its foot when it landed on the branch. When it attempted to take off the line probably got caught in the tree branch, and the more the bird tried to free itself, the more it wrapped itself around the branch. Finally its foot was so tightly entangled around the branch that the bird could not move and eventually died on the branch. The bird was removed from the tree and disposed of.

We've searched the web at http://www.regulations.gov for any comments from the first round due on January 5, 2012 and could not find any. The situation we described last year (see below) has not improved. We are waiting for additional rules from DOE but don't believe they'll provide the needed relief from regulatory burden. This past year we've invested $250,000 in energy testing. Those resources could have been used to develop new and better products. We expect to invest more dollars in 2012. Since your last request for information in 2011, we did more research in EPACT 2005. The

The robot moves in ahead of rescuers to evaluate precarious environments and help them plan the rescue mission. One of the biggest obstacles to rescuing miners after an accident is the unknown level of danger. Before rescuers are able to get miners to safety, they must assess the situation, often taking up time critical to the success of the rescue. Poisonous gases, flooded tunnels, explosive vapors and unstable walls and roofs are among the potentially deadly conditions and unknown obstacles that can slow rescue efforts.

Why Sequence Two Micromonosporas?  

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

Two Micromonosporas? Two Micromonosporas? DOE-JGi will sequence the genomes of two members of the Micromonosporaceae: Micromonospora strain L5, which was originally isolated from roots of Casuarina equisetifolia, an actinorhizal plant that is nodulated by Frankia, and recently shown to fix atmospheric nitrogen into ammonia; and the ATCC strain M. aurantiaca 27029, which, based on 16S RNA DNA phylogeny, is closely related to strain L5. Species of Micromonospora are important for biocontrol and bioremediation. They have incredible metabolic versatility, among which nitrogen fixation has been added to the traits exhibited by these microbes. Micromonospora strain L5. Micrograph courtesy Ann M. Hirsch.

Use of nuclear explosives for excavation of a sea-level canal across the Negev Desert in Israel, connecting the Mediterranean with the Gulf of Aqaba  

SciTech Connect

Another interesting application of nuclear excavation would be a sea- level canal 160 miles long across Israel, connecting the Mediterranean with the Gulf of Aqaba (and thus the Red Sea and the Indian Ocean). Such a canal would be a strategically valuable alternate to the present Suez Canal and would probably contribute greatly to the economic development of the surrounding area. The difference in elevation between sea level and the Dead Sea (30 miles away and 1286 feet below sea level) might also be used to generate hydroelectric power. The maximum depth of excavation to be encountered is on the order of 1500 feet. Conventional methods of excavation of this magnitude are prohibitively expensive, if indeed possible, but it appears that nuclear explosives could be profitably applied to this situation.

Structural reliability analysis and seismic risk assessment  

SciTech Connect

This paper presents a reliability analysis method for safety evaluation of nuclear structures. By utilizing this method, it is possible to estimate the limit state probability in the lifetime of structures and to generate analytically the fragility curves for PRA studies. The earthquake ground acceleration, in this approach, is represented by a segment of stationary Gaussian process with a zero mean and a Kanai-Tajimi Spectrum. All possible seismic hazard at a site represented by a hazard curve is also taken into consideration. Furthermore, the limit state of a structure is analytically defined and the corresponding limit state surface is then established. Finally, the fragility curve is generated and the limit state probability is evaluated. In this paper, using a realistic reinforced concrete containment as an example, results of the reliability analysis of the containment subjected to dead load, live load and ground earthquake acceleration are presented and a fragility curve for PRA studies is also constructed.

Life Redefined: Microbes Built with Arsenic  

DOE Green Energy (OSTI)

Life can survive in many harsh environments, from extreme heat to the presence of deadly chemicals. However, life as we know it has always been based on the same six elements -- carbon, oxygen, nitrogen, hydrogen, sulfur and phosphorus. Now it appears that even this rule has an exception. In the saline and poisonous environment of Mono Lake, researchers have found a bacterium that can grow by incorporating arsenic into its structure in place of phosphorus. X-ray images taken at SLAC's synchrotron light source reveal that this microbe may even use arsenic as a building block for DNA. Please join us as we describe this discovery, which rewrites the textbook description of how living cells work.

Structural analysis of the equipment removal system for tank 241SY101  

DOE Green Energy (OSTI)

The calculations documented in this report show that the ERS major components are structurally qualified to complete the objective, i.e., to install the removed equipment into a shipping container and transport and store the container at the Central Waste Complex (CWC). The analysis for the structural members of the ERS components considers live load with an impact factor of 125 % added to dead load. An allowable stress of one-third yield is used for all structural components carrying the load based on DOE-RL-92-36. Adherence to DOE-RL-92-36 is not a code requirement. However, the loads considered make this factor of safety appropriate. The calculations meet the strength requirements of the American Institute for Steel Construction (ASIC 1989) for all non-critical structural elements.

Dragging Heavy Quarks in Quark Gluon Plasma at the Large Hadron Collider  

E-Print Network (OSTI)

The drag and diffusion coefficients of charm and bottom quarks propagating through quark gluon plasma (QGP) have been evaluated for conditions relevant to nuclear collisions at Large Hadron Collider (LHC). The dead cone and Landau-Pomeronchuk-Migdal (LPM) effects on radiative energy loss of heavy quarks have been considered. Both radiative and collisional processes of energy loss are included in the {\\it effective} drag and diffusion coefficients. With these effective transport coefficients we solve the Fokker Plank (FP) equation for the heavy quarks executing Brownian motion in the QGP. The solution of the FP equation has been used to evaluate the nuclear suppression factor, $R_{\\mathrm AA}$ for the non-photonic single electron spectra resulting from the semi-leptonic decays of hadrons containing charm and bottom quarks. The effects of mass on $R_{\\mathrm AA}$ has also been highlighted.

Evaluation of rotary drum screens used to protect juvenile salmonids in the Yakima River Basin, Washington, USA  

DOE Green Energy (OSTI)

The purpose of this study is to assess the design and operation of rotary drum screens. Chinook salmon Oncorhynchus tshawytscha and steelhead O. mykiss are the potentially affected fish. Cold-branded fish are released upstream of the screen facilities. For descaling tests, the fish are captured as they exit the facility and are examined for injuries, descaling, and post-test mortalities. For screen passage tests, nets are placed in the irrigation ditch, downstream of the screen facilities, to determine if fish can pass through or over the screens. More than 100 tests have been conducted with almost 35,000 fish. Additionally, nearly 2000 native fish have been evaluated. Usually less than 2% of the test fish are injured or dead, and the condition of test fish does not differ from the controls. Less than 2% of the fish pass through or over the screens when the screen seals are properly installed and maintained.

El Paso electric 345 kV, Springerville to Deming, transmission line project, New Mexico  

SciTech Connect

Construction of a 213.5-mile, 345-kilovolt (kV) transmission line is proposed from the El Paso Electric Company Luna substation, 1.5 miles north of Deming, to a point on the existing Tucson Electric Power Company transmission line near Red Hill, in New Mexico. Counties in New Mexico that could be directly affected are Luna, Sierra, Socorro, Catron, and Grant. The proposed line would use wood towers, 51 to 55 feet high, placed at an average interval of 800 feet. More equipment would be added to the Luna substation, consisting of a 345-kV circuit breaker, two switches, a dead-end tower, and relay equipment. Communication and control would be provided through a microwave radio system. The transmission line would be paralleled by a two-track road for routine patrol. Estimated cost of the project is $42.9 million.

Novel Silicon n-on-p Edgeless Planar Pixel Sensors for the ATLAS upgrade  

E-Print Network (OSTI)

In view of the LHC upgrade phases towards HL-LHC, the ATLAS experiment plans to upgrade the Inner Detector with an all-silicon system. The n-on-p silicon technology is a promising candidate for the pixel upgrade thanks to its radiation hardness and cost effectiveness, that allow for enlarging the area instrumented with pixel detectors. We report on the development of novel n-in-p edgeless planar pixel sensors fabricated at FBK (Trento, Italy), making use of the "active edge" concept for the reduction of the dead area at the periphery of the device. After discussing the sensor technology and fabrication process, we present device simulations (pre- and post-irradiation) performed for different sensor configurations. First preliminary results obtained with the test-structures of the production are shown.

Distributed Real-Time Emulation of Formally-Defined Patterns for Safe Medical Device Control  

E-Print Network (OSTI)

Safety of medical devices and of their interoperation is an unresolved issue causing severe and sometimes deadly accidents for patients with shocking frequency. Formal methods, particularly in support of highly reusable and provably safe patterns which can be instantiated to many device instances can help in this regard. However, this still leaves open the issue of how to pass from their formal specifications in logical time to executable emulations that can interoperate in physical time with other devices and with simulations of patient and/or doctor behaviors. This work presents a specification-based methodology in which virtual emulation environments can be easily developed from formal specifications in Real-Time Maude, and can support interactions with other real devices and with simulation models. This general methodology is explained in detail and is illustrated with two concrete scenarios which are both instances of a common safe formal pattern: one scenario involves the interaction of a provably safe ...

Polar distortion in ultra-thin BaTiO3 films by in situ LEED-IV  

Science Conference Proceedings (OSTI)

Phase stability in nanoscale ferroelectrics is governed by the interplay of electrostatic depolarization energy, domain formation, adsorption, and surface band bending. Using in situ low-energy electron-diffraction intensity versus voltage (LEED I-V), we have characterized 4 and 10 ML BaTiO{sub 3} films, grown using pulsed laser deposition with fully compressive strain on a SrRuO{sub 3}/SrTiO{sub 3} substrate. LEED I-V reveals a single surface dead layer and a monodomain vertically polarized state below. The single orientation is attributed to the intrinsic imprint asymmetry and the stability of a polarized phase to compensation of depolarizing charges by dipoles induced by surface stress.

Cooling system for a bearing of a turbine rotor  

SciTech Connect

In a gas turbine, a bore tube assembly radially inwardly of an aft bearing conveys cooling steam to the buckets of the turbine and returns the cooling steam to a return. To cool the bearing and thermally insulate the bearing from the cooling steam paths, a radiation shield is spaced from the bore tube assembly by a dead air gap. Additionally, an air passageway is provided between the radiation shield and the inner surface of an aft shaft forming part of the rotor. Air is supplied from an inlet for flow along the passage and radially outwardly through bores in the aft shaft disk to cool the bearing and insulate it from transfer of heat from the cooling steam.

High Level Architecture (HLA) federation with Umbra and OPNET federates.  

SciTech Connect

Network-centric systems that depend on mobile wireless ad hoc networks for their information exchange require detailed analysis to support their development. In many cases, this critical analysis is best provided with high-fidelity system simulations that include the effects of network architectures and protocols. In this research, we developed a high-fidelity system simulation capability using an HLA federation. The HLA federation, consisting of the Umbra system simulator and OPNET Modeler network simulator, provides a means for the system simulator to both affect, and be affected by, events in the network simulator. Advances are also made in increasing the fidelity of the wireless communication channel and reducing simulation run-time with a dead reckoning capability. A simulation experiment is included to demonstrate the developed modeling and simulation capability.

Nonlinear response of vessel walls due to short-time thermomechanical loading  

Science Conference Proceedings (OSTI)

Maintaining structural integrity of the reactor pressure vessel (RPV) during a postulated core melt accident is an important safety consideration in the design of the vessel. This study addresses the failure predictions of the vessel due to thermal and pressure loadings fro the molten core debris depositing on the lower head of the vessel. Different loading combinations were considered based on the dead load, yield stress assumptions, material response and internal pressurization. The analyses considered only short term failure (quasi static) modes, long term failure modes were not considered. Short term failure modes include plastic instabilities of the structure and failure due to exceeding the failure strain. Long term failure odes would be caused by creep rupture that leads to plastic instability of the structure. Due to the sort time durations analyzed, creep was not considered in the analyses presented.

Significance of Selective Predation and Development of Prey Protection Measures for Juvenile Salmonids in the Columbia and Snake River Reservoirs: Annual Progress Report, February 1991-February 1992.  

DOE Green Energy (OSTI)

This document is the 1991 annual report of progress for the Bonneville Power Administration (BPA) research Project conducted by the US Fish and Wildlife Service (FWS). Our approach was to present the progress achieved during 1991 in a series of separate reports for each major project task. Each report is prepared in the format of a scientific paper and is able to stand alone, whatever the state of progress or completion. This project has two major goals. One is to understand the significance of selective predation and prey vulnerability by determining if substandard juvenile salmonids (dead, injured, stressed, diseased, or naive) are more vulnerable to predation by northern squawfish, than standard or normal juvenile salmonids. The second goal is to develop and test prey protection measures to control predation on juvenile salmonids by reducing predator-smolt encounters or predator capture efficiency.

In 2008, African swine fever was introduced into Georgia, after which it spread to neighboring Armenia, Azerbaijan, and the Russian Federation. That same year, PCR and sequence analysis identifi ed African swine fever virus in samples from 3 dead female wild boars in northwestern Iran. Wild boars may serve as a reservoir. African swine fever (ASF) is a notifiable, highly contagious, lethal, hemorrhagic disease in domestic pigs (1,2). ASF virus (ASFV) (International Committee on Taxonomy of Viruses database no. 00.002.0.01.001), an enveloped double-stranded DNA virus, is the only known DNA arbovirus (3). Maintenance and transmission of ASFV involves cycling of virus between soft ticks of the genus Ornithodoros and wild pigs (warthogs, bush pigs, and giant forest boars) (1,2).

Coal-water slurry fuel internal combustion engine and method for operating same  

SciTech Connect

An internal combustion engine fueled with a coal-water slurry is described. About 90 percent of the coal-water slurry charge utilized in the power cycle of the engine is directly injected into the main combustion chamber where it is ignited by a hot stream of combustion gases discharged from a pilot combustion chamber of a size less than about 10 percent of the total clearance volume of main combustion chamber with the piston at top dead center. The stream of hot combustion gases is provided by injecting less than about 10 percent of the total coal-water slurry charge into the pilot combustion chamber and using a portion of the air from the main combustion chamber that has been heated by the walls defining the pilot combustion chamber as the ignition source for the coal-water slurry injected into the pilot combustion chamber.

New approaches to estimation of magnetotelluric parameters  

DOE Green Energy (OSTI)

Fully efficient robust data processing procedures were developed and tested for single station and remote reference magnetotelluric (Mr) data. Substantial progress was made on development, testing and comparison of optimal procedures for single station data. A principal finding of this phase of the research was that the simplest robust procedures can be more heavily biased by noise in the (input) magnetic fields, than standard least squares estimates. To deal with this difficulty we developed a robust processing scheme which combined the regression M-estimate with coherence presorting. This hybrid approach greatly improves impedance estimates, particularly in the low signal-to-noise conditions often encountered in the dead band'' (0.1--0.0 hz). The methods, and the results of comparisons of various single station estimators are described in detail. Progress was made on developing methods for estimating static distortion parameters, and for testing hypotheses about the underlying dimensionality of the geological section.

A microchannel crossflow fluid heat exchanger and a method for its fabrication are disclosed. The heat exchanger is formed from a stack of thin metal sheets which are bonded together. The stack consists of alternating slotted and unslotted sheets. Each of the slotted sheets includes multiple parallel slots which form fluid flow channels when sandwiched between the unslotted sheets. Successive slotted sheets in the stack are rotated ninety degrees with respect to one another so as to form two sets of orthogonally extending fluid flow channels which are arranged in a crossflow configuration. The heat exchanger has a high surface to volume ratio, a small dead volume, a high heat transfer coefficient, and is suitable for use with fluids under high pressures. The heat exchanger has particular application in a Stirling engine that utilizes a liquid as the working substance.

Science Conference Proceedings (OSTI)

Detailed state-of-the-art building energy simulation models from nations participating in International Energy Agency (IEA) Task VIII are used to develop a quantitative procedure to evaluate more simplified design tools. Simulations are performed with the detailed models on a series of cases that progress systematically from the extremely simple to the relatively realistic. Output values for the cases, such as annual loads, annual maximum and minimum temperatures, and peak loads, are used to set target ranges with which the results from more simplified design tools can be compared. The more realistic cases, although geometrically simple, test the ability of the design tools to model such combined effects as thermal mass, direct gain windows, overhangs, internally generated heat, and dead-band and set-back thermostat control strategies. 5 refs., 9 figs., 4 tabs.

Exciton photoluminescence and energy in a percolation cluster of ZnSe quantum dots as a fractal object  

SciTech Connect

The results of studies of samples containing ZnSe quantum dots with a density corresponding to or considerably higher than the exciton percolation threshold, at which quantum dots form conglomerates, are reported. Excitonic emission from a percolation cluster of bound quantum dots as a fractal object is observed for the first time. Analysis of the structure of the photoluminescence spectra shows that the spectra are determined by the contribution of exciton states that belong to different structural elements of the percolation cluster, specifically, to the skeleton (backbone), dangling (dead) ends, and internal hollow spaces. A qualitative model is proposed to interpret the dependence of the exciton energy in these structural elements on the concentration of quantum dots in the material.

In Outer Space without a Space Suit?  

E-Print Network (OSTI)

The author proposes and investigates his old idea - a living human in space without the encumbrance of a complex space suit. Only in this condition can biological humanity seriously attempt to colonize space because all planets of Solar system (except the Earth) do not have suitable atmospheres. Aside from the issue of temperature, a suitable partial pressure of oxygen is lacking. In this case the main problem is how to satiate human blood with oxygen and delete carbonic acid gas (carbon dioxide). The proposed system would enable a person to function in outer space without a space suit and, for a long time, without food. That is useful also in the Earth for sustaining working men in an otherwise deadly atmosphere laden with lethal particulates (in case of nuclear, chemical or biological war), in underground confined spaces without fresh air, under water or a top high mountains above a height that can sustain respiration.

A Novel Antimatter Detector with Application to Dark Matter Searches  

Science Conference Proceedings (OSTI)

We report on recent accelerator testing of a prototype general antiparticle spectrometer (GAPS). GAPS uses a novel approach for indirect dark matter searches that exploits the antideuterons produced in neutralino-neutralino annihilations. GAPS captures these antideuterons into a target with the subsequent formation of exotic atoms. These exotic atoms decay with the emission of x-rays of precisely defined energy and a correlated pion signature from nuclear annihilation. This signature uniquely characterizes the antideuterons. Preliminary analysis of data from a prototype GAPS in an antiproton beam at the KEK accelerator in Japan has confirmed the multiple x-ray/pion star topology and indicated x-ray yields consistent with prior expectations. Moreover, our success in utilizing solid rather than gas targets represents a significant simplification over our original approach and offers potential gains in sensitivity through reduced dead mass in the target area.

An internal combustion engine fueled with a coal-water slurry is described. About 90 percent of the coal-water slurry charge utilized in the power cycle of the engine is directly injected into the main combustion chamber where it is ignited by a hot stream of combustion gases discharged from a pilot combustion chamber of a size less than about 10 percent of the total clearance volume of main combustion chamber with the piston at top dead center. The stream of hot combustion gases is provided by injecting less than about 10 percent of the total coal-water slurry charge into the pilot combustion chamber and using a portion of the air from the main combustion chamber that has been heated by the walls defining the pilot combustion chamber as the ignition source for the coal-water slurry injected into the pilot combustion chamber.

Use of ceragenins to create novel biofouling resistant water-treatment membranes.  

SciTech Connect

Scoping studies have demonstrated that ceragenins, when linked to water-treatment membranes have the potential to create biofouling resistant water-treatment membranes. Ceragenins are synthetically produced molecules that mimic antimicrobial peptides. Evidence includes measurements of CSA-13 prohibiting the growth of and killing planktonic Pseudomonas fluorescens. In addition, imaging of biofilms that were in contact of a ceragenin showed more dead cells relative to live cells than in a biofilm that had not been treated with a ceragenin. This work has demonstrated that ceragenins can be attached to polyamide reverse osmosis (RO) membranes, though work needs to improve the uniformity of the attachment. Finally, methods have been developed to use hyperspectral imaging with multivariate curve resolution to view ceragenins attached to the RO membrane. Future work will be conducted to better attach the ceragenin to the RO membranes and more completely test the biocidal effectiveness of the ceragenins on the membranes.

Profile-Based Adaption . . .  

E-Print Network (OSTI)

Cache decay is a set of leakage-reduction mechanisms that put cache lines that have not been accessed for a specific duration into a low-leakage standby mode. This duration is called the decay interval, and its optimal value varies across applications. This paper provides an extended discussion of the results previously presented in our journal paper [13]. It describes an adaptation technique that analytically finds the optimal decay interval through profiling, and shows that the most important variables required for finding the optimal decay interval can be estimated with a reasonable degree of accuracy using profiling. This work explicitly trades off the leakage power saved in putting both the live and dead lines into standby mode, against its performance and energy costs. It achieves energy savings close to what can be obtained with an omniscient choice of per-benchmark optimal decay interval.

Profile-based adaptation for cache decay  

E-Print Network (OSTI)

Cache decay is a leakage-reduction mechanism that puts cache lines that have not been accessed for a specific duration into a lowleakage standby mode. This duration is called the decay interval, and its optimal value varies across applications. This paper describes an adaptation technique that analytically finds the optimal decay interval through profiling, and shows that the most important variables required for finding the optimal decay interval can be estimated using profiling with a reasonable degree of accuracy. Unlike previous methods that attempt to put only dead lines into standby mode, this work explicitly trades off the leakage power saved in putting live lines into standby against its performance and energy costs. It also combines traditional DVS with cache decay using an analysis and obtains results close to what can be obtained with an omniscient choice of per-benchmark optimal decay interval. 1

Velocity characteristics of the flow in motored engines. Final report  

DOE Green Energy (OSTI)

The influence of piston-head geometry, compression and rotational speed has been investigated. Measurements and calculations, without compression have shown the influence of a cylindrical bowl to be negligible; it is expected, and work is in progress to obtain direct evidence, that the influence will be significant with compression. Measurements in a Petter engine have, however, shown that compression has little influence at bottom dead center on the expansion stroke and that a substantial region of solid-body rotation exists in both cases. The influence of rotational speed on the flow patterns and turbulence intensity have been shown to be small except in the immediate vicinity of the inlet port and for rotational speeds (<100 rpm) when the flow is not turbulent. 25 references, 11 figures.

Transverse section radionuclide scanning system  

DOE Patents (OSTI)

This invention provides a transverse section radionuclide scanning system for high-sensitivity quantification of brain radioactivity in cross-section picture format in order to permit accurate assessment of regional brain function localized in three-dimensions. High sensitivity crucially depends on overcoming the heretofore known raster type scanning, which requires back and forth detector movement involving dead-time or partial enclosure of the scan field. Accordingly, this invention provides a detector array having no back and forth movement by interlaced detectors that enclose the scan field and rotate as an integral unit around one axis of rotation in a slip ring that continuously transmits the detector data by means of laser emitting diodes, with the advantages that increased amounts of data can be continuously collected, processed and displayed with increased sensitivity according to a suitable computer program.

Explosive Model Tarantula 4d/JWL++ Calibration of LX-17  

Science Conference Proceedings (OSTI)

Tarantula is an explosive kinetic package intended to do detonation, shock initiation, failure, corner-turning with dead zones, gap tests and air gaps in reactive flow hydrocode models. The first, 2007-2008 version with monotonic Q is here run inside JWL++ with square zoning from 40 to 200 zones/cm on ambient LX-17. The model splits the rate behavior in every zone into sections set by the hydrocode pressure, P + Q. As the pressure rises, we pass through the no-reaction, initiation, ramp-up/failure and detonation sections sequentially. We find that the initiation and pure detonation rate constants are largely insensitive to zoning but that the ramp-up/failure rate constant is extremely sensitive. At no time does the model pass every test, but the pressure-based approach generally works. The best values for the ramp/failure region are listed here in Mb units.

Microchannel crossflow fluid heat exchanger and method for its fabrication  

DOE Patents (OSTI)

A microchannel crossflow fluid heat exchanger and a method for its fabrication are disclosed. The heat exchanger is formed from a stack of thin metal sheets which are bonded together. The stack consists of alternating slotted and unslotted sheets. Each of the slotted sheets includes multiple parallel slots which form fluid flow channels when sandwiched between the unslotted sheets. Successive slotted sheets in the stack are rotated ninety degrees with respect to one another so as to form two sets of orthogonally extending fluid flow channels which are arranged in a crossflow configuration. The heat exchanger has a high surface to volume ratio, a small dead volume, a high heat transfer coefficient, and is suitable for use with fluids under high pressures. The heat exchanger has particular application in a Stirling engine that utilizes a liquid as the working substance. 9 figs.

Effects of natural gas composition on ignition delay under diesel conditions  

DOE Green Energy (OSTI)

Effects of variations in natural gas composition on autoignition of natural gas under direct-injection (DI) diesel engine conditions were studied experimentally in a constant-volume combustion vessel and computationally using a chemical kinetic model. Four fuel blends were investigated: pure methane, a capacity weighted mean natural gas, a high ethane content natural gas, and a natural gas with added propane typical of peak shaving conditions. Experimentally measured ignition delays were longest for pure methane and became progressively shorter as ethane and propane concentrations increased. At conditions characteristic of a DI compression ignition natural gas engine at Top Dead Center (CR=23:1, p = 6.8 MPa, T = 1150K), measured ignition delays for the four fuels varied from 1.8 ms for the peak shaving and high ethane gases to 2.7 ms for pure methane. Numerically predicted variations in ignition delay as a function of natural gas composition agreed with these measurements.

Advanced Photon Source RF Beam Position Monitor System Upgrade Design and Commissioning  

E-Print Network (OSTI)

This paper describes the Advanced Photon Source (APS) storage ring mono-pulse rf beam position monitor (BPM) system upgrade. The present rf BPM system requires a large dead time of 400 ns between the measured bunch and upstream bunch. The bunch pattern is also constrained by the required target cluster of six bunches of 7 mA minimum necessary to operate the receiver near the top end of the dynamic range. The upgrade design objectives involve resolving bunches spaced as closely as 100 ns. These design objectives require us to reduce receiver front-end losses and reflections. An improved trigger scheme that minimizes systematic errors is also required. The upgrade is in the final phases of installation and commissioning at this time. The latest experimental and commissioning data and results will be presented.

TARANTULA 2011 in JWL++  

SciTech Connect

Using square zoning, the 2011 version of the kinetic package Tarantula matches cylinder data, cylinder dead zones, and cylinder failure with the same settings for the first time. The key is the use of maximum pressure rather than instantaneous pressure. Runs are at 40, 200 and 360 z/cm using JWL++ as the host model. The model also does run-to-detonation, thin-pulse initiation with a P-t curve and air gap crossing, all in cylindrical geometry. Two sizes of MSAD/LX-10/LX-17 snowballs work somewhat with these settings, but are too weak, so that divergent detonation is a challenge for the future. Butterfly meshes are considered but do not appear to solve the issue.

Microfluidic interconnects  

DOE Patents (OSTI)

A miniature connector for introducing microliter quantities of solutions into microfabricated fluidic devices, and which incorporates a molded ring or seal set into a ferrule cartridge, with or without a compression screw. The fluidic connector, for example, joins standard high pressure liquid chromatography (HPLC) tubing to 1 mm diameter holes in silicon or glass, enabling ml-sized volumes of sample solutions to be merged with .mu.l-sized devices. The connector has many features, including ease of connect and disconnect; a small footprint which enables numerous connectors to be located in a small area; low dead volume; helium leak-tight; and tubing does not twist during connection. Thus the connector enables easy and effective change of microfluidic devices and introduction of different solutions in the devices.

Micromachined magnetohydrodynamic actuators and sensors  

DOE Patents (OSTI)

A magnetohydrodynamic (MHD) micropump and microsensor which utilizes micromachining to integrate the electrodes with microchannels and includes a magnet for producing magnetic fields perpendicular to both the electrical current direction and the fluid flow direction. The magnet can also be micromachined and integrated with the micropump using existing technology. The MHD micropump, for example, can generate continuous, reversible flow, with readily controllable flow rates. The flow can be reversed by either reversing the electrical current flow or reversing the magnetic field. By mismatching the electrodes, a swirling vortex flow can be generated for potential mixing applications. No moving parts are necessary and the dead volume is minimal. The micropumps can be placed at any position in a fluidic circuit and a combination of micropumps can generate fluidic plugs and valves.

Solids transportation model of an industrial rotary dryer  

SciTech Connect

A complete simulation model has been developed for an industrial rotary dryer to account for the heat and mass exchange between the solids and the gas. This simulator is mainly composed of three models: solids transportation model, furnace model, and gas model. The solids transportation model is the modified Cholette-Cloutier model. It consists of a series of interactive reservoirs which are subdivided into an active and dead compartments to account for the characteristic extended tail of the residence time distribution (RTD) curves observed in industrial dryers. To expand the validity of the model, experiments have been performed in an industrial rotary dryer to obtain RTD curves under different mineral concentrate and gas flow rates. This paper describes these experiments and presents the variation of the average residence time and model parameters as function of solids and gas flow rates.

Ni coarsening in the three-phase solid oxide fuel cell anode - a phase-field simulation study  

E-Print Network (OSTI)

Ni coarsening in Ni-yttria stabilized zirconia (YSZ) solid oxide fuel cell anodes is considered a major reason for anode degradation. We present a predictive, quantative modeling framework based on the phase-field approach to systematically examine coarsening kinetics in such anodes. The initial structures for simulations are experimentally acquired functional layers of anodes. Sample size effects and error analysis of contact angles are examined. Three phase boundary (TPB) lengths and Ni surface areas are quantatively identified on the basis of the active, dead-end, and isolated phase clusters throughout coarsening. Tortuosity evolution of the pores is also investigated. We find that phase clusters with larger characteristic length evolve slower than those with smaller length scales. As a result, coarsening has small positive effects on transport, and impacts less on the active Ni surface area than the total counter part. TPBs, however, are found to be sensitive to local morphological features and are only i...

Fluid mechanics of membrane-coated ceramic filters  

SciTech Connect

Analytical models are formulated for evaluating the fluid mechanics of membrane-coated, dead-end ceramic filters. The models are applicable to forward flow as in the filtration mode and reverse flow as in the back-pulse cleaning mode. General criteria are derived to size the filter passages from considerations of Darcy pressure drop, friction pressure drop, and the dynamic head. These criteria together with Reynolds numbers are shown to provide measures of nonuniformities in face velocity and pressure that develop in the filter passages for atmospheric and high-pressure applications. A methodology is presented for optimizing the venturi geometry from the standpoint of minimizing pulse gas usage and controlling the thermal load imposed on the filter assembly.

By inhibiting release of the neurotransmitter acetylcholine, for example, the neurotoxin produced by the bacterium Clostridium botulinum interferes with nerve impulses and causes a paralysis of respiratory and skeletal muscles that can cause death. Researchers from Stanford University have now determined the first structure of a CNT in complex with its target. The structure at a resolution of 2.1 Å, together with enzyme kinetic data, reveals an array of active sites (exosites) that give the CNT its deadly specificity.

The Autonomous Pathogen Detection System (APDS)  

SciTech Connect

Shaped like a mailbox on wheels, it's been called a bioterrorism ''smoke detector.'' It can be found in transportation hubs such as airports and subways, and it may be coming to a location near you. Formally known as the Autonomous Pathogen Detection System, or APDS, this latest tool in the war on bioterrorism was developed at Lawrence Livermore National Laboratory to continuously sniff the air for airborne pathogens and toxins such as anthrax or plague. The APDS is the modern day equivalent of the canaries miners took underground with them to test for deadly carbon dioxide gas. But this canary can test for numerous bacteria, viruses, and toxins simultaneously, report results every hour, and confirm positive samples and guard against false positive results by using two different tests. The fully automated system collects and prepares air samples around the clock, does the analysis, and interprets the results. It requires no servicing or human intervention for an entire week. Unlike its feathered counterpart, when an APDS unit encounters something deadly in the air, that's when it begins singing, quietly. The APDS unit transmits a silent alert and sends detailed data to public health authorities, who can order evacuation and begin treatment of anyone exposed to toxic or biological agents. It is the latest in a series of biodefense detectors developed at DOE/NNSA national laboratories. The manual predecessor to APDS, called BASIS (for Biological Aerosol Sentry and Information System), was developed jointly by Los Alamos and Lawrence Livermore national laboratories. That system was modified to become BioWatch, the Department of Homeland Security's biological urban monitoring program. A related laboratory instrument, the Handheld Advanced Nucleic Acid Analyzer (HANAA), was first tested successfully at LLNL in September 1997. Successful partnering with private industry has been a key factor in the rapid advancement and deployment of biodefense instruments such as these. The APDS technology has been licensed and is currently undergoing commercialization.

Black Holes in Galaxy Mergers: Evolution of Quasars  

E-Print Network (OSTI)

Based on numerical simulations of gas-rich galaxy mergers, we discuss a model in which quasar activity is tied to the self-regulated growth of supermassive black holes in galaxies. Nuclear inflow of gas attending a galaxy collision triggers a starburst and feeds black hole growth, but for most of the duration of the starburst, the black hole is heavily obscured by surrounding gas and dust which limits the visibility of the quasar, especially at optical and UV wavelengths. Eventually, feedback energy from accretion heats the gas and expels it in a powerful wind, leaving a 'dead quasar'. Between buried and dead phases there is a window during which the galaxy would be seen as a luminous quasar. Because the black hole mass, radiative output, and distribution of obscuring gas and dust all evolve strongly with time, the duration of this phase of observable quasar activity depends on both the waveband and imposed luminosity threshold. We determine the observed and intrinsic lifetimes as a function of luminosity and frequency, and calculate observable lifetimes ~10 Myr for bright quasars in the optical B-band, in good agreement with empirical estimates and much smaller than the black hole growth timescales ~100 Myr, naturally producing a substantial population of 'buried' quasars. However, observed and intrinsic energy outputs converge in the IR and hard X-ray bands as attenuation becomes weaker and chances of observation greatly increase. We obtain the distribution of column densities along sightlines in which the quasar is seen above a given luminosity, and find that our result agrees remarkably well with observed estimates of the column density distribution from the SDSS for appropriate luminosity thresholds.

The nature of electrical interaction of Schottky contacts  

SciTech Connect

Electrical interaction between metal-semiconductor contacts combined in a diode matrix with a Schottky barrier manifests itself in an appreciable variation in their surface potentials and static current-volt-characteristics. The necessary condition for appearance of electrical interaction between such contacts consists in the presence of a peripheral electric field (a halo) around them; this field propagates to a fairly large distances (<30 {mu}m). The sufficient condition is the presence of regions where the above halos overlap. It has been shown that variation in the surface potential and the current-voltage characteristics of contacts occurs under the effect of the intrinsic electric field of the contact's periphery and also under the effect of an electric field at matrix periphery; the latter field is formed as a result of superposition of electric fields of halos which form its contacts. The degree of the corresponding effect is governed by the distance between contacts and by the total charge of the space charge regions for all contacts of the matrix: their number, sizes (diameter D{sub i,j}), concentration of doping impurities in the semiconductor N{sub D}, and physical nature of a metal-semiconductor system with a Schottky barrier (with the barrier height {phi}{sub b}). It is established that bringing the contacts closer leads to a relative decrease in the threshold value of the 'dead' zone in the forward current-voltage characteristics, an increase in the effective height of the barrier, and an insignificant increase in the nonideality factor. An increase in the total area of contacts (a total electric charge in the space charge region) in the matrix brings about an increase in the threshold value of the 'dead' zone, a relative decrease in the effective barrier height, and an insignificant increase in the ideality factor.

A Research on Production Optimization of Coupled Surface and Subsurface Model  

E-Print Network (OSTI)

One of the main objectives in the Oil & Gas Industry is to constantly improve the reservoir management capabilities by using production optimization strategies that can positively impact the so-called net-present value (NPV) of a given project. In order to achieve this goal the industry is faced with the difficult task of maximizing hydrocarbon production and minimizing unwanted fluids, such as water, while sustaining or even enhancing the reservoir recovery factor by handling properly the fluids at surface facilities. A key element in this process is the understanding of the interactions between subsurface and subsurface dynamics in order to provide insightful production strategies which honor reservoir management surface facility constraints. The implementation of the ideal situation of fully coupling surface/subsurface has been hindered by the required computational efforts involved in the process. Consequently, various types of partially coupling that require less computational efforts are practically implemented. Due to importance of coupling surface and subsurface model on production optimization and taking the advantage of advancing computational performance, this research explores the concept of surface and subsurface model couplings and production optimization. The research aims at demonstrating the role of coupling of surface and subsurface model on production optimization under simple production constraint (i.e. production and injection pressure limit). The normal production prediction runs with various reservoir description (homogeneous-low permeability, homogeneous-high permeability, and heterogeneous permeability) and different fluid properties (dead-oil PVT and lived-oil PVT) were performed in order to understand the effect of coupling level, and coupling scheme with different reservoir descriptions and fluid properties on production and injection rate prediction. The result shows that for dead-oil PVT, the production rate from different coupling schemes in homogeneous and heterogeneous reservoir is less sensitive than lived-oil PVT cases. For lived-oil PVT, the production rate from different coupling schemes in homogeneous high permeability and heterogeneous permeability are more sensitive than homogeneous low permeability. The production optimization on water flooding under production and injection constraint cases is considered here also.

Captive Rearing Program for Salmon River Chinook Salmon, 2000 Project Progress Report.  

SciTech Connect

During 2000, the Idaho Department of Fish and Game (IDFG) continued to develop techniques to rear chinook salmon Oncorhynchus tshawytscha to sexual maturity in captivity and to monitor their reproductive performance under natural conditions. Eyed-eggs were collected to establish captive cohorts from three study streams and included 503 eyed-eggs from East Fork Salmon River (EFSR), 250 from the Yankee Fork Salmon River, and 304 from the West Fork Yankee Fork Salmon River (WFYF). After collection, the eyed-eggs were immediately transferred to the Eagle Fish Hatchery, where they were incubated and reared by family group. Juveniles collected the previous summer were PIT and elastomer tagged and vaccinated against vibrio Vibrio spp. and bacterial kidney disease before the majority (approximately 75%) were transferred to the National Marine Fisheries Service, Manchester Marine Experimental Station for saltwater rearing through sexual maturity. Smolt transfers included 158 individuals from the Lemhi River (LEM), 193 from the WFYF, and 372 from the EFSR. Maturing fish transfers from the Manchester facility to the Eagle Fish Hatchery included 77 individuals from the LEM, 45 from the WFYF, and 11 from the EFSR. Two mature females from the WFYF were spawned in captivity with four males in 2000. Only one of the females produced viable eggs (N = 1,266), which were placed in in-stream incubators by personnel from the Shoshone-Bannock Tribe. Mature adults (N = 70) from the Lemhi River were released into Big Springs Creek to evaluate their reproductive performance. After release, fish distributed themselves throughout the study section and displayed a progression of habitat associations and behavior consistent with progressing maturation and the onset of spawning. Fifteen of the 17 suspected redds spawned by captive-reared parents in Big Springs Creek were hydraulically sampled to assess survival to the eyed stage of development. Eyed-eggs were collected from 13 of these, and survival ranged from 0% to 96%, although there was evidence that some eggs had died after reaching the eyed stage. Six redds were capped in an attempt to document fry emergence, but none were collected. A final hydraulic sampling of the capped redds yielded nothing from five of the six, but 75 dead eggs and one dead fry were found in the sixth. Smothering by fine sediment is the suspected cause of the observed mortality between the eyed stage and fry emergence.

Early pregnancy diagnosis and embryo/fetus mortality in cattle  

E-Print Network (OSTI)

Pregnancy diagnosis by transrectal ultrasonography (using a 5 MHZ linear probe) presented the maximum sensitivity and negative predictive values at day 26 and day 29 after estrus in heifers and cows, respectively. Palpation per rectum using the fetal membrane slip for pregnancy diagnosis did not increase embryo/fetus mortality when compared with a positive control group of non-palpated females. The use of a controlled randomized block design was a useful approach to study this problem. Blocking for category and number of embryos allowed us to remove these confounding factors. Factors that affected pregnancy loss during the first four months of pregnancy were: period of pregnancy, age of the animal, number of previous lactations and number of embryos. Pregnancy loss was higher during the embryonic than fetal periods. Spontaneous embryo/fetal mortality increased with the age of the animal and lactation number. The risk of spontaneous embryo/fetus mortality was higher in twin than in single pregnancies. Two types of embryo/fetus mortality were noted: Type I and Type II. Type I was characterized by presence of positive fetal membrane slip by palpation per rectum, signs of degeneration by transrectal ultrasonography and persistence of a functional corpus luteum. The uterus took approximately 3 weeks to be noted clean by transrectal ultrasonography and the animals showed estrus one month after the conceptus was diagnosed dead. Type II was characterized by absence of positive signs of pregnancy by palpation per rectum, absence of signs of degeneration by transrectal ultrasonography and absence of a functional corpus luteum. Pregnancy loss in nuclear transfer derived embryos was higher compared to in vivo derived embryos produced by artificial insemination. Pregnancy loss occurred mainly during the transition from the embryonic to the fetal period. Embryo/fetus mortality detected was Type I. Progesterone produced by the corpus luteum was noted at pregnancy levels for approximately two weeks after embryo/fetus death. Protein B, a hormonal placental marker, was maintained at pregnancy levels for approximately 3 weeks after embryo/fetus death. No differences in the levels of the two hormones were noted when comparing females with dead or live conceptuses.

Development of Low Temperature Combustion Modes to Reduce Overall Emissions from a Medium-Duty, Four Cylinder Diesel Engine  

E-Print Network (OSTI)

Low temperature combustion (LTC) is an appealing new method of combustion that promises low nitric oxides and soot emissions while maintaining or improving on engine performance. The three main points of this study were to develop and validate an engine model in GT-Power capable of implementing LTC, to study parametrically exhaust gas recirculation (EGR) and injection timing effects on performance and emissions, and to investigate methods to decrease pressure rise rates during LTC operation. The model was validated at nine different operating points, 3 speeds and 3 loads, while the parametric studies were conducted on 6 of the 9 operating points, 3 speeds and 2 loads. The model consists of sections that include: cylinders, ports, intake and exhaust manifolds, EGR system, and turbocharger. For this model, GT-Power calculates the combustion using a multi-zone, quasi-dimensional model and a knock-induced combustion model. The main difference between them is that the multi-zone model is directly injected while the knock model is port injected. A variety of sub models calculate the fluid flow and heat transfer. A parametric study varying the EGR and the injection timing to determine the optimal combination was conducted using the multi-zone model while a parametric study that just varies EGR is carried out using the knock model. The first parametric study showed that the optimal EGR and injection timing combination for the low loads occurred at high levels of EGR (60 percent) and advanced injection timings (30 to 40 crank angle degrees before top dead center). The optimal EGR and injection timing combination for the high loads occurred at low levels of EGR (30 percent to 40 percent) and retarded injection timings (7.5 to 5 crank angle degrees before top dead center). The knock model determined that the ideal EGR ratio for homogeneous charge compression ignition (HCCI) operation varied from 30 percent to 45 percent, depending on the operating condition. Three methods were investigated as possible ways to reduce pressure rise rates during LTC operation. The only feasible method was the multiple injection strategy which provided dramatically reduced pressure rise rates across all EGR levels and injection timings.

Three-dimensional analysis of AP600 standard plant shield building roof  

SciTech Connect

The AP600 passive containment vessel is surrounded by a concrete cylindrical shell covered with a truncated conical roof. This roof supports the passive containment cooling system (PCS) annular tank, shield plate and other nonstructural attachments. When the shield building is subjected to different loading combinations as defined in the Standard Review Plan (SRP), some of the sections in the shield building could experience forces in excess of their design values. This report summarized the three-dimensional finite element analysis that was conducted to review the adequacy of the proposed Westinghouse shield building design. The ANSYS finite element software was utilized to analyze the Shield Building Roof (SBR) under dead, snow, wind, thermal and seismic loadings. A three-dimensional model that included a portion of the shield building cylindrical shell, the conical roof and its attachments, the eccentricities at the cone-cylinder connection and at the compression ring and the PCS tank was developed. Mesh sensitivity studies were conducted to select appropriate element size in the cylinder, cone, near air intakes and in the vicinity of the eccentricities. Also, a study was carried out to correctly idealize the water-structure interaction in the PCS tank. Response spectrum analysis was used to calculate the internal forces at different sections in the SBR under Safe Shutdown Earthquake (SSE). Forty-nine structural modes and twenty sloshing modes were used. Two horizontal components of the SSE together with a vertical component were used. Modal stress resultants were combined taking into account the effects of closely spaced modes. The three earthquake directions were combined by the Square Root of the Sum Squares method. Two load combinations were studied. The load combination that included dead, snow, fluid, thermal and seismic loads was selected to be the most critical. Interaction diagrams for critical sections were developed and used to check the design adequacy. The results demonstrated that provided area of steal on each face of several sections of the AP600 SBR was inadequate. This was also noticed when comparing the total provided area of steel per section, i.e., the area of steel on both faces. The discrepancy between Westinghouse results and these reported herein could have resulted from the different finite element mesh sizes and the assumption used in Westinghouse design.

Satellite image analysis for surveillance, vegetation and climate change  

Science Conference Proceedings (OSTI)

Recently, many studies have provided abundant evidence to show the trend of tree mortality is increasing in many regions, and the cause of tree mortality is associated with drought, insect outbreak, or fire. Unfortunately, there is no current capability available to monitor vegetation changes, and correlate and predict tree mortality with CO{sub 2} change, and climate change on the global scale. Different survey platforms (methods) have been used for forest management. Typical ground-based forest surveys measure tree stem diameter, species, and alive or dead. The measurements are low-tech and time consuming, but the sample sizes are large, running into millions of trees, covering large areas, and spanning many years. These field surveys provide powerful ground validation for other survey methods such as photo survey, helicopter GPS survey, and aerial overview survey. The satellite imagery has much larger coverage. It is easier to tile the different images together, and more important, the spatial resolution has been improved such that close to or even higher than aerial survey platforms. Today, the remote sensing satellite data have reached sub-meter spatial resolution for panchromatic channels (IKONOS 2: 1 m; Quickbird-2: 0.61 m; Worldview-2: 0.5 m) and meter spatial resolution for multi-spectral channels (IKONOS 2: 4 meter; Quickbird-2: 2.44 m; Worldview-2: 2 m). Therefore, high resolution satellite imagery can allow foresters to discern individual trees. This vital information should allow us to quantify physiological states of trees, e.g. healthy or dead, shape and size of tree crowns, as well as species and functional compositions of trees. This is a powerful data resource, however, due to the vast amount of the data collected daily, it is impossible for human analysts to review the imagery in detail to identify the vital biodiversity information. Thus, in this talk, we will discuss the opportunities and challenges to use high resolution satellite imagery and machine learning theory to monitor tree mortality at the level of individual trees.

Upgrading Methane Using Ultra-Fast Thermal Swing Adsorption  

Science Conference Proceedings (OSTI)

The purpose of this project is to design and demonstrate an approach to upgrade low-BTU methane streams from coal mines to pipeline-quality natural gas. The objective of Phase I of the project was to assess the technical feasibility and cost of upgrading low-BTU methane streams using ultra-fast thermal swing adsorption (TSA) using Velocys modular microchannel process technology. The objective of Phase II is to demonstrate the process at the bench-scale. Natural gas upgrading systems have six main unit operations: feed compressor, dehydration unit, nitrogen rejection unit, deoxygenator, carbon dioxide scrubber, and a sales compressor. The NRU is the focus of the development program, and a bench-scale demonstration has been initiated. The Velocys NRU system targets producing methane with greater than 96% purity and at least 90% recovery for final commercial operation. A preliminary cost analysis of the methane upgrading system, including the Velocys NRU, suggests that costs below $2.00 per million (MM) BTU methane may be achieved. The cost for a conventional methane upgrading system is well above $2.30 per MM BTU, as benchmarked in an Environmental Protection Agency study. The project is on schedule and on budget. Task 4, a bench-scale demonstration of the ultra-fast TSA system is complete. Rapid thermal swing of an adsorbent bed using microchannels has been successfully demonstrated and the separation of a 70% methane and 30% nitrogen was purified to 92% methane. The bench-scale demonstration unit was small relative to the system dead volume for the initial phase of experiments and a purge step was added to sweep the dead volume prior to desorbing the bed and measuring purity. A technical and economic feasibility assessment was completed in Task 3. The proposed Velocys technology appears feasible for the methane upgrading market. Evaluated categories include adsorbent selection, rapid-cycle valve selection, microchannel manufacturability assessment, and system design and cost. The selected adsorbent, granular microporous carbon from either Barnaby-Sutcliffe or Calgon, experimentally demonstrated sufficient methane capacity under differential temperature at 100 pounds per square inch gauge. Several valve options were identified, including candidates that can operate millions of cycles between refurbishment. The microchannel adsorber and desorber designs were made using internal Velocys manufacturability standards, and the associated costs are acceptable as included with the complete nitrogen rejection unit (NRU) cost projection. A system design and cost estimate was completed for the NRU section of the methane upgrading system. As integrated into the complete system, the cost is in line with the market requirement.

Substrate Recognition Strategy for Botulinum Neurotoxin  

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

Substrate Recognition Strategy for Botulinum Neurotoxin Print Substrate Recognition Strategy for Botulinum Neurotoxin Print Clostridal neurotoxins (CNTs) are the causative agents of the neuroparalytic diseases botulism and tetanus. By inhibiting release of the neurotransmitter acetylcholine, for example, the neurotoxin produced by the bacterium Clostridium botulinum interferes with nerve impulses and causes a paralysis of respiratory and skeletal muscles that can cause death. Researchers from Stanford University have now determined the first structure of a CNT in complex with its target. The structure at a resolution of 2.1 Å, together with enzyme kinetic data, reveals an array of active sites (exosites) that give the CNT its deadly specificity. Botulism Toxin The best thing one can say about botulism is that it is relatively rare. At worst, botulism can ultimately result in death due to respiratory failure resulting from paralysis of the muscles used in breathing. The muscle paralysis is caused by the neurotoxin produced by the bacterium Clostridium botulinum, which can be ingested with contaminated food, enter the body through wounds, or (in the case of infants where there is little competition from other microbes) germinate in the intestine from spores. Given early after onset of symptoms, an antitoxin exists that can prevent further damage, but a more effective treatment for this and other neurotoxin-caused illnesses, such as tetanus, await a more detailed understanding of how the toxin works at the molecular level.

Current Oil Formation Current Oil Formation Name: Jerry Status: n/a Grade: other Country: USA Date: Winter 2011-2012 Question: Is oil still being formed in an ongoing fashion by geologic and physical processes just as it was millions of years ago? Replies: Jerry, The process of converting organic detritus into oil only requires that the organic material (dead plants, animals, etc) undergo decomposition in an oxygen poor environment. Long chain hydrocarbons are formed in this way. So in places where there is a lot of organic material buried under rock or below the pinocline of some body of water (a depth and temperature of water where little roiling happens and hence oxygen does not appreciably mix in), then the conversion of organic material into oil should be happening. This might lead you to wonder why are we concerned that fossil fuel is being depleted - and this goes to how much oil is being extracted and used, versus how much oil is being produced by the natural process.

Snapping Turtles Snapping Turtles Nature Bulletin No. 7 March 24, 1945 Forest Preserve District of Cook County Clayton F. Smith, President Dr. David H. Thompson, Zoologist SNAPPING TURTLES A SNAPPING TURTLE, a BLANDING'S TURTLE and two PAINTED TURTLES were found along the shores of McGinnis Slough on March 10. They were alive but very sluggish. On March 17, nineteen snappers, another Blanding and several painted turtles were found alive. All were very sluggish although it was a warm, sunny day. The two largest snappers, weighing about 25 pounds each, later died. Numbers of dead painted turtles were found along the shore. This was unusually early for turtles to be out. Turtles and frogs "hole up" for the winter and hibernate in the mud under the ice. When animals hibernate, their body processes do not stop completely; they merely slow way down. Some species slow down more than others but all of them continue to breathe or use oxygen, and their hearts continue to beat very slowly. Although turtles can remain under water for long periods in the hot summer, they have lungs and must come up to breathe air once in a while. So it is with frogs. Both turtles and frogs must have some oxygen when they hibernate for the winter under the ice. They get this oxygen by absorbing oxygen, dissolved in the water, through the membranes of their mouths and throats. Some kinds of animals may also take dissolved oxygen in through their skins.

Protozoa Protozoa Name: Alex Beck Location: N/A Country: N/A Date: N/A Question: How many species of protozoa are there? How many are poisonous? What type is most deadly? How do they protozoa catch their food? How do protozoa digest their food? How big is the largest protozoa? How small is the smallest protozoa? Replies: There are about 200,000 living species of protists. This is approximate because scientists do not agree on exactly what organisms should be classified as protists, and because all species have not been found yet. I don't know about poisonous ones except for a type called a dinoflagellate that causes the famous "red tide". It can kill fish when it is present in large numbers, and if eaten by clams and other shellfish, it can poison people who eat the shellfish. Protists capture their food in many ways. Some, like the ameba, surround it with their cell membranes. Other, like the paramecium, have a permanent groove in their membrane, and sweep food into it with little hairs called cilia. Digestion is inside the single cell, not inside a gut (which is actually outside your body if you think about it) like more advanced animals. I don't know sizes well enough to answer your last two questions. I checked all this information (most of which was in my head) in a college biology textbook called "Biology" by Solomon et al

It is a huge wildlife sanctuary wherein no weapon may be carried and no hunting, trapping or molestation of any mammal or bird is permitted. Aside from fish management, the wildlife has been left alone to work out its own systems of checks and balances. There has been no attempt to remove surplus populations; no control of any predator other than wild cats and dogs. None is needed. Dead or hollow trees have been allowed to stand, or lie where they fall, because they furnish homes for many kinds of wildlife and go back into the soil to maintain the health of the woodland. There has been considerable reforestation of open tracts formerly farmed and, in some areas, planting of shrubs and vines which provide food for wildlife.

Maybe they are useless, or even a problem. Maybe the fish wishes it didn't have scales! I say this only to emphasize two things: First of all, when you think scientifically, the MOST IMPORTANT thing is to be very careful not to assume you know something when you really don't. What I mean by that is: don't think you know the answer before you are dead positive absolutely for-sure 100% certain that you do. Why? Why make a big fuss over being so very careful? Well, I hate to tell you this (but you probably already know it), it's just SO EASY for human beings to fool themselves, to think they know the answers when they really don't know AT ALL what they are talking about.

Carpenter Ants Carpenter Ants Nature Bulletin No. 598 April 2, 1960 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H. Thompson Senior Naturalist CARPENTER ANTS Cutting stove wood for home heating and cooking used to be a regular wintertime job. Then, when the trees are frozen solid, the work is easy. A large chunk of red oak, for example, pops wide open at a single stroke of the ax. Sometimes the fresh surface exposes a cluster of hibernating Carpenter Ants stiff and numb with cold inside a network of frost-lined tunnels. Warmed by the sun or the heat from a campfire they slowly begin to move their legs and feebly creep away. In summer we see these carpenter ants prowling tree trunks and the forest floor in search of food. Occasionally, if we sit down on a fallen log or tap on a dead tree, dozens of them come rushing out with their antennae waving to see what is causing the disturbance. Less often, a colony is found enlarging its quarters. One ant after another runs out and drops a pellet of wood onto a pile of sawdust on the ground below, then hurries back inside for another load.

The Japanese Beetle

Japanese Beetle Japanese Beetle Nature Bulletin No. 579 November 7, 1959 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H. Thompson, Senior Naturalist THE JAPANESE BEETLE The deadly warfare between mankind and the insects never ends. Every minute of the day and night, billions of them are attacking our crops, orchards, forests and grasslands. They attack our homes, gardens, and even ourselves. Of those that were inadvertently brought to the United States from foreign countries, one of the most destructive is the Japanese Beetle. This pest was discovered in a nursery near Riverton, New Jersey, in 1916. Evidently some of its grubs -- the larvae-- had arrived a few years earlier in earth around the roots of plants imported from Japan. Over there, native parasites keep this beetle under control. Here, with none of those natural enemies, it multiplied and spread rapidly. Also, before we established stringent preventive measures, it was widely distributed in shipments of nursery and greenhouse plants. Now it hitchhikes on railroad trains and airplanes. Except northern New England, all but three states east of the Great Plains are infested by the Japanese beetle.

Thiang Yian Wong, Robert Schwarzenbacher and Robert C. Liddington Thiang Yian Wong, Robert Schwarzenbacher and Robert C. Liddington The Burnham Institute, 10901 North Torrey Pines Road, La Jolla, CA 92037. Anthrax Toxin is a major virulence factor in the infectious disease, Anthrax1. This toxin is produced by Bacillus anthracis, which is an encapsulated, spore-forming, rod-shaped bacterium. Inhalation anthrax, the most deadly form, is contracted through breathing spores. Once spores germinate within cells of the immune system called macrophages2, bacterial cells are released into the bloodstream. There they proliferate rapidly and secrete Anthrax Toxin, ultimately leading to septic shock and death. Although antibiotics may be used to kill the bacteria, the level of toxin has often become so high in the bloodstream that removing the bacteria alone is not sufficient to prevent death. Therefore, the design of anti-toxins offers the prospect of treatment in the advanced stages of infection. Together with collaborators from the NIH and Harvard Medical School, we are involved in the atomic resolution study of the Anthrax Toxin components and their complexes, including small molecules with therapeutic potential. Data collection at SSRL and other synchrotron radiation sources has been key to the advances made in this research so far and is expected to play a continuing role in the future.

They die from diseases, infections, injuries, burns, drowning, malnutrition, and sometimes just plain old age. Walking through the woods we see, here and there, dead or dying trees of various kinds. For example: a big white oak, with its bark ripped from crown to root, was literally cooked by a bolt of lightning during a summer thunderstorm. In a grove of black oaks, many are dying lingering deaths from infected wounds started years ago when an autumn fire swept through the fallen leaves and scorched the living wood. In a dense forest there are many that have lost the battle for space and sunlight. In some places we see trees that are slowly starving because dashing rains have carried away the fertile topsoil and the trampling feet of picnickers have injured the shallow roots that bring them food.

Rosettes Rosettes Nature Bulletin No. 662 January 13, 1962 Forest Preserve District of Cook County John J. Duffy, President David H. Thompson, Senior Naturalist PLANT ROSETTES In winter our landscape is mostly leafless trees silhouetted against the sky, and the dead stalks of wildflowers, weeds and tall grasses -- with or without a blanket of snow. Some snows lie on the ground for only a few days. Others follow one after another and cover the ground with white for weeks at a time. Soon the eye begins to hunger for a glimpse of something green and growing. Then, in sunny spots where the snow has melted or where youngsters have cleared it away, there appear clusters of fresh green leaves pressed tight to the soil. Whether it is a dandelion in the lawn, a pansy in a flower border, or a thistle in a vacant lot, such a typical leaf cluster -- called a winter rosette -- is a ring of leaves around a short central stem. The leaves are narrow at the base, wider toward the tip, and spread flat on the ground with little or no overlap. This arrangement gives full exposure to sunlight and close contact with the warmer soil beneath. Such plants continue to grow, sometimes faster, sometimes slower, even under snow, throughout winter.

Smith, President Roberts Mann, Supt. of Conservation THE PORTAGE Chicagoland has been millions of years in the making. But for 25,000 years it has been certain that this would be the crossroads for any great civilization on this continent and one of the major metropolitan centers of the world. Even the prehistoric mound-building Indians of the south and those of the north who built effigy mounds, met here to trade for copper. Later the Sioux, the Iroquois, the Illini, the western Algonquins which included the Potawatomi, and other once-powerful Indian rations paid tribute to the strategic Importance of this region with their dead. Finally, in the 1600's, came the white man. Here he discovered a portage across the low continental divide between Lake Michigan and the DesPlaines River, between the watershed of the Great Lakes emptying into the Atlantic Ocean and the watershed of the Mississippi emptying into the Gulf of Mexico.

Outbreak? Outbreak? Name: Nathan W Brandsma Status: N/A Age: N/A Location: N/A Country: N/A Date: N/A Question: What are the chances that a diseases, like in the movie outbreak, could occur? Replies: The movie Outbreak is about a disease caused by a virus. Many diseases are actually caused by viruses (AIDS, chicken pox, colds, etc). Most viral diseases can only be prevented (by getting vaccinated), but can't be cured; though we can often reduce the symptoms (like anti-itch cream for chicken pox, or cough drops for a cold). Viral diseases are usually spread from one person to another. What people sometimes worry about is a new virus that is deadly but can be spread really easily (like through the air or by touch). Since there are so many people in the world today, this virus could travel all over the place going from person to person. Nobody knows what the chances are that a virus like that will turn up. Fortunately, there are a number of organizations that keep a close watch on infectious diseases, and have lots of doctors who specialize in containing "outbreaks." So it is something to think about, but I wouldn't stay up at night worrying about it!

Why is grass green?  

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

is grass green? is grass green? Name: Bob Whitbeck Status: N/A Age: N/A Location: N/A Country: N/A Date: N/A Question: What causes grass to be green? Replies: Bob, Grass and most other plants are green because they contain a pigment known as chlorophyll. The chlorophyll is used in the process of photosynthesis where a plant produces sugar in the presence of sunlight. In fact the word 'photosynthesis' means literally to synthesize or 'make' from light (photo). There are, of course some plants which do not contain chlorophyll, and these generally get their nutrition (food) by other means. Some examples are the fungi which decompose dead, and sometimes living, tissue, for their food. You will find that a green plant needs light to make food. If the source of light is cut off, the plant dies. Mushrooms, which are fungi, do not require light to make food (they decompose matter as I mentioned above) and you can find mushrooms growing in almost total darkness.

Use of CORRTEX to measure explosive performance and stem behavior in oil shale fragmentation tests  

SciTech Connect

Continuous Reflectometry for Radius vs Time Experiments (CORRTEX) was used to monitor several conditions of blasts such as the detonation velocity of the explosive column, the functioning of different types of initiators and initiation schemes, and the behavior of the stemming column confining the explosive. The CORRTEX data were also used to deduce the occurrence of dead-pressing of ANFO slurry. Measurements of propagation speeds of shock waves in the stem column with various cables allowed some conclusions concerning bridging, stem failure, and stress levels in the stem. CORRTEX used time-domain reflectometry to interrogate the two-way transit time (TWTT) of a coaxial cable. As the shock front advanced the cable was shorted or destroyed and the resultant TWTT was shorter. Interpretation of these changes as a function of time allowed the position of the shock front to be inferred also as a function of time. This paper describes in some detail the CORRTEX technique and how it was applied to in-situ measurements. Detonation velocities are provided for pelletized ANFO and TNT as well as various ANFO slurries. Observations are made on stem performance as well as shock propagation velocities in several stem materials. Cable characteristics and methods of cable selection are discussed as are techniques for instrumentation of complex blasts to provide initiation time and burn velocity. 3 references, 7 figures.

THE GRAVO-MAGNETO LIMIT CYCLE IN ACCRETION DISKS  

Science Conference Proceedings (OSTI)

Previous theoretical studies have found that repeating outbursts can occur in certain regions of an accretion disk due to sudden transitions in time from gravitationally produced turbulence to magnetically produced turbulence. We analyze the disk evolution in a state diagram that plots the mass accretion rate versus disk surface density. We determine steady state accretion branches that involve gravitational and magnetic sources of turbulence. Using time-dependent numerical disk simulations, we show that cases having outbursts track along a nonsteady 'dead zone' branch and some steady state accretion branches. The outburst is the result of a rapid inter-branch transition. The gravo-magneto outbursts are then explained on this diagram as a limit cycle that is analogous to the well-known S-curve that has been applied to dwarf nova outbursts. The diagram and limit cycle provide a conceptual framework for understanding the nature of the outbursts that may occur in accretion disks of all scales, from circumplanetary to protoplanetary to active galactic nucleus accretion disks.

Self-Assembly of Nanocomponents into Composite Structures: Derivation and Simulation of Langevin Equations  

E-Print Network (OSTI)

The kinetics of the self-assembly of nanocomponents into a virus, nanocapsule, or other composite structure is analyzed via a multiscale approach. The objective is to achieve predictability and to preserve key atomic-scale features that underlie the formation and stability of the composite structures. We start with an all-atom description, the Liouville equation, and the order parameters characterizing nanoscale features of the system. An equation of Smoluchowski type for the stochastic dynamics of the order parameters is derived from the Liouville equation via a multiscale perturbation technique. The self-assembly of composite structures from nanocomponents with internal atomic structure is analyzed and growth rates are derived. Applications include the assembly of a viral capsid from capsomers, a ribosome from its major subunits, and composite materials from fibers and nanoparticles. Our approach overcomes errors in other coarse-graining methods which neglect the influence of the nanoscale configuration on the atomistic fluctuations. We account for the effect of order parameters on the statistics of the atomistic fluctuations which contribute to the entropic and average forces driving order parameter evolution. This approach enables an efficient algorithm for computer simulation of self-assembly, whereas other methods severely limit the timestep due to the separation of diffusional and complexing characteristic times. Given that our approach does not require recalibration with each new application, it provides a way to estimate assembly rates and thereby facilitate the discovery of self-assembly pathways and kinetic dead-end structures.

Implications for C-14 Dating of the Jenkins-Fischbach Effect and Possible Fluctuation of the Solar Fusion Rate  

E-Print Network (OSTI)

It has long been known that the C-14 calibration curve, which relates the known age of tree rings to their apparent C-14 ages, includes a number of "wiggles" which clearly are not experimental errors or other random effects. A reasonable interpretation of these wiggles is that they indicate that the Sun's fusion "furnace" is pulsating, perhaps for reasons similar to that of the Cepheid variables, albeit under a very different regime of pressure and temperature. If this speculation is correct, we are seeing the heartbeat of the Sun-the C-14 calibration curve is the Sun's "neutrino-cardiogram." Elevated neutrino flux during a relatively brief period would have two effects: (1) a surge in C-14 fraction in the atmosphere, which would make biological samples that were alive during the surge appear to be "too young" (2) depletion of C-14 in the biotic matter already dead at the time of the surge; this is a consequence of the recently discovered Jenkins-Fischbach effect, which is an observed correlation between nuclear decay rates and solar activity or Earth-Sun distance. In addition, the precise value at any given time of the "half-life" of any unstable isotope-including C-14-must now be considered in doubt, since the Jenkins-Fischbach effect implies that we may no longer view the decay rate of an isotope as intrinsically governed and therefore a constant of Nature.

A comparison between direct spark ignition and prechamber ignition in an internal combustion engine  

DOE Green Energy (OSTI)

We simulated the flow field and flame propagation near top dead center in a generic large-bore internal combustion engine using the COYOTE computer program, which is based on the full Navier-Stokes equations for a fluid mixture. The combustion chamber is a right circular cylinder, and the main charge is uniformly premixed. The calculations are axisymmetric. The results illustrate the differences in flow patterns, flame propagation, and thermal NO production between ignition with a spark plug and with a small prechamber. In the spark-ignited case, the flame propagates away from the spark plug approximately as a segment of a spherical surface, just as expected. With the prechamber, a high speed jet of hot combustion products shoots into the main chamber, quickly producing a large flame sheet that spreads along the piston face. The prechamber run consumes all of the fuel in half the time required by the spark-ignited case. The two cases produce comparable amounts of thermal NO at the end of fuel combustion.

Improving the gas-chromatographic determination of the composition of the gas liberated from a battery  

SciTech Connect

Normally, gas chromatography is used for analyzing the gas composition that is liberated when batteries operate. Earlier work describes a gas-chromatographic technique for determining the composition of gas liberated from a battery. According to this reference, the gas is collected in an inverted burette over water. The gas is either sampled with a batching valve or with a medical syringe, which pierces the connecting vacuum hoses. The gas sample is injected into the chromatographic evaporator, and is separated on the chromatographic column into its individual components, each of which is analyzed on the detector. The method described was used to study gas liberation during the storage of charged nickel-zinc batteries. In the method described above, a high proportion of the gas specimen that accumulates and is collected in the measuring system occurs in the dead space volume. In this situation, it is very difficult to determine the liberated gas composition with a high degree of accuracy when the gas is liberated at low rates. Moreover, this method does not provide reliable system air tightness during long term operation of the batteries. 5 refs., 2 figs., 1 tab.

Quality studies of the data taking conditions for the Auger Fluorescence Detector  

E-Print Network (OSTI)

As more than half of the Fluorescence Detector (FD) of the Auger Observatory is completed, data taking is becoming a routine job. It is then necessary to follow strict procedures to assure the quality of the data. An overview of the data taking methods is given. The nature of the FD background signal is due to the night sky brightness (stars and planet faint light, moonlight, twilight, airglow, zodiacal and artificial light) and to the electronic background (photomultiplier and electronic noise). The analysis of the fluctuations in the FADC signal (variance analysis), directly proportional to the background mean light level, performed for each night of data taking is used to monitor the FD background signal. The data quality is analysed using different techniques, described in detail. Examples of trigger rates, number of stereo events, dead time due to moonlight, weather or hardware problems are given. The analysis comprises several months of data taking, giving an overview of the FD capabilities, performance and allowing a systematic study of data and their correlation with the environment.

Relationship of diets and environmental contaminants in wintering bald eagles. [Haliaeetus leucocephalus  

SciTech Connect

We investigated the relationship between diets and potential hazards in contaminants of wintering bald eagles (Haliaeetus leucocephalus) in the Klamath Basin of northern California and southern Oregon. We studied diets by identifying remains of 913 prey items found at perches, examining 341 castings collected from communal night roots, and observing foraging eagles. We determined residues of organochlorine compounds, lead (Pb), and mercury (Hg) in bald eagles and their prey by analyzing eagle blood samples and carcasses and 8 major prey species. Bald eagles fed largely on waterfowl by scavenging cholera-killed ducks and geese and on microtine rodents during mid- to late winter. Residues of organochlorine pesticides and Hg in prey were low, and polychlorinated biphenyls (PCB's) were detected in low concentrations in 9% of prey samples. Means Pb concentrations in prey ranged from 0.15 to 4.79 ppm. Mercury was detected in all eagle blood samples, and Pb was detected in 41% of the bald eagle blood samples. Mean Pb concentration in livers of dead eagles was 2.09 ppm and ranged as high as 27 ppm in an eagle that died of Pb poisoning. Prey of the eagles were relatively free of contaminants with the possible exception of embedded Pb shot in waterfowl, which may present a potential for Pb poisoning of eagles.

Characterization of Epitaxial Film Silicon Solar Cells Grown on Seeded Display Glass: Preprint  

Science Conference Proceedings (OSTI)

We report characterizations of epitaxial film crystal silicon (c-Si) solar cells with open-circuit voltages (Voc) above 560 mV. The 2-um absorber cells are grown by low-temperature (EAGLE XG display glass coated with a layer-transferred (LT) Si seed. The high Voc is a result of low-defect epitaxial Si (epi-Si) growth and effective hydrogen passivation of defects. The quality of HWCVD epitaxial growth on seeded glass substrates depends on the crystallographic quality of the seed and the morphology of the epitaxial growth surface. Heterojunction devices consist of glass/c-Si LT seed/ epi n+ Si:P/epi n- Si:P/intrinsic a-Si:H/p+ a-Si:H/ITO. Similar devices grown on electronically 'dead' n+ wafers have given Voc {approx}630 mV and {approx}8% efficiency with no light trapping features. Here we study the effects of the seed surface polish on epi-Si quality, how hydrogenation influences the device character, and the dominant junction transport physics.

Determination of white phosphorus residues in ducks: An atomic emission detection/compound-independent calibration-based method of generating residue data for risk assessment and environmental monitoring  

Science Conference Proceedings (OSTI)

Analysis of phosphorus concentrations in the gizzards of ducks harvested from munitions sites is necessary to ascertain if acute phosphorus toxicity was the cause of death and to estimate potential secondary hazards to predators and scavengers, such as eagles that readily consume the dead ducks. Gas chromatography-atomic emission detection analysis permitted compound-independent quantification of white phosphorus standards following analysis of the stable phosphorus-containing compound triethyl phosphate. The white phosphorus standards were then used to quantify white phosphorus residues in duck gizzard extracts by gas chromatography-flame photometric detection analysis. For gizzards containing less than 0.01 {micro}g of phosphorus, quantification was based on a three-point calibration curve. For gizzards containing 0.01 {micro}g or more of white phosphorus, single-point calibration was used. Mean recoveries for phosphorus-fortified gizzards ranged from 73 to 91%. The method limit of detection was 0.013 {micro}g of phosphorus. This method was successfully applied to the quantification of white phosphorus in ducks collected from Eagle River Flats, AK. Potential applications to risk assessment and environmental monitoring are also discussed.

Design of a Fractional Order Phase Shaper for Iso-damped Control of a PHWR under Step-back Condition  

E-Print Network (OSTI)

Phase shaping using fractional order (FO) phase shapers has been proposed by many contemporary researchers as a means of producing systems with iso-damped closed loop response due to a stepped variation in input. Such systems, with the closed loop damping remaining invariant to gain changes can be used to produce dead-beat step response with only rise time varying with gain. This technique is used to achieve an active step-back in a Pressurized Heavy Water Reactor (PHWR) where it is desired to change the reactor power to a pre-determined value within a short interval keeping the power undershoot as low as possible. This paper puts forward an approach as an alternative for the present day practice of a passive step-back mechanism where the control rods are allowed to drop during a step-back action by gravity, with release of electromagnetic clutches. The reactor under a step-back condition is identified as a system using practical test data and a suitable Proportional plus Integral plus Derivative (PID) contro...

Optimization of laser scribing for thin-film PV modules. Annual technical progress report, 12 April 1995--11 April 1996  

DOE Green Energy (OSTI)

One of the most important aspects in moving from the cell level to the integrated module level in thin-film photovoltaics is to achieve reliable and reproducible cell interconnects having low series resistance and high shunt resistance, and to do this with a minimum of dead area between cells. It is known that mechanical scribing often produces considerable damage (e.g., film tearing) surrounding the scribe. Laser scribing has shown the potential for superior scribe widths and profiles for many of the materials involved with thin-film PV. However, problems arc also known to occur with a heat-affected zone around the scribe, and for some materials and some focus conditions high positive ridges or collars are left along the scribe line. The commercially-available scribing systems have been optimized typically for other applications and other materials such as scribing of crystalline Si. Optimum operation for thin-film PV materials has been investigated by several PV manufacturers but there has been limited discussion of problems or of optimum parameters in the open literature. Furthermore, to our knowledge, there has been little investigation of the applicability, for thin-film PV, of laser systems other than the traditional cw lamp-pumped, Q-switched Nd:YAG.

Old and new neutron stars  

Science Conference Proceedings (OSTI)

The youngest known radiopulsar in the rapidly spinning magnetized neutron star which powers the Crab Nebula, the remnant of the historical supernova explosion of 1054 AD. Similar neutron stars are probably born at least every few hundred years, but are less frequent than Galactic supernova explosions. They are initially sources of extreme relativistic electron and/or positron winds (approx.10/sup 38/s/sup -1/ of 10/sup 12/ eV leptons) which greatly decrease as the neutron stars spin down to become mature pulsars. After several million years these neutron stars are no longer observed as radiopulsars, perhaps because of large magnetic field decay. However, a substantial fraction of the 10/sup 8/ old dead pulsars in the Galaxy are the most probable source for the isotropically distributed ..gamma..-ray burst detected several times per week at the earth. Some old neutron stars are spun-up by accretion from companions to be resurrected as rapidly spinning low magnetic field radiopulsars. 52 references, 6 figures, 3 tables.

Concentrations of CO and CO/sub 2/ are measured using infrared gas analyzers and the H/sub 2/O content by means of a trace moisture analyzer. The graphite specimen is 1-1/2'' long x 3/4'' diameter and is stressed by dead weight loading between an alumina hammer and anvil. The load is applied by a simple lever arm arrangement through a metal bellows on top of a mullite lined furnace. The reaction rate is determined via the concentrations of CO and CO/sub 2/ in the effluent gas. Initial set up and testing of the apparatus is almost completed and initial experience is that the apparatus meets the requirements of the proposed research. Samples of two pyrolytic graphites have been doped with boron to concentrations of 30 and 400 ppM for irradiation at 1300/sup 0/C later in the year in order to determine the possible effect of boron on vacancy nucleation at such high temperatures.

Accurate determination of Curium and Californium isotopic ratios by inductively coupled plasma quadrupole mass spectrometry (ICP-QMS) in 248Cm samples for transmutation studies  

Science Conference Proceedings (OSTI)

The French Atomic Energy Commission has carried out several experiments including the mini-INCA (INcineration of Actinides) project for the study of minor-actinide transmutation processes in high intensity thermal neutron fluxes, in view of proposing solutions to reduce the radiotoxicity of long-lived nuclear wastes. In this context, a Cm sample enriched in {sup 248}Cm ({approx}97 %) was irradiated in thermal neutron flux at the High Flux Reactor (HFR) of the Laue-Langevin Institute (ILL). This work describes a quadrupole ICP-MS (ICP-QMS) analytical procedure for precise and accurate isotopic composition determination of Cm before sample irradiation and of Cm and Cf after sample irradiation. The factors that affect the accuracy and reproducibility of isotopic ratio measurements by ICP-QMS, such as peak centre correction, detector dead time, mass bias, abundance sensitivity and hydrides formation, instrumental background, and memory blank were carefully evaluated and corrected. Uncertainties of the isotopic ratios, taking into account internal precision of isotope ratio measurements, peak tailing, and hydrides formations ranged from 0.3% to 1.3%. This uncertainties range is quite acceptable for the nuclear data to be used in transmutation studies.

Structure-toxicity assessment of metabolites of the aerobic bacterial transformation of substituted naphthalenes  

Science Conference Proceedings (OSTI)

Pseudomonas fluorescens 5R, a naphthalene-degrading bacterium isolated from manufactured gas plant soil contaminated with polycyclic aromatic hydrocarbons, was examined for its degradative capacity of a number of substituted naphthalenes. In general, those compounds substituted on only one ring with an electrically neutral substituent were found to be transformed primarily to substituted salicylic acids according to the classical (NAH7) naphthalene dioxygenase-initiated upper pathway reactions of the naphthalene degradative pathway (i.e., the NAH system). Dimethylnaphthalenes with a substituent on each ring, and certain halogenated naphthalenes, were transformed via a monohydroxylation reaction to form hydroxylated dead-end products. Of the substituted salicylic acids examined, only 3- and 4-methylsalicylic acid, the respective products of the degradation of 1- and 2-methylnaphthalene, were further degraded by salicylate hydroxylase and catechol 2,3-dioxygenase, the first two enzymes of the NAH lower pathway. Using the Tetrahymena pyriformis acute toxicity assay, many of the monohydroxylated products of incomplete biodegradation were found to be polar narcotics. Substituted salicylic acids that are not further degraded by the NAH lower pathway were found to be toxic via carboxylic acid narcosis.

Socio-cultural acceptability of cadaver Transplantation in Iran  

E-Print Network (OSTI)

Organ transplantation is known to be a new and innovative treatment for patients with progressive organ failures. The present study investigates the current status of transplantation from cadaver along with its socio-cultural acceptability in Iran. The present study is a descriptive research in a systematic review method. Here, by investigating previously conducted researches in Iran during the period 2002-2010, the status of transplantation from cadaver and its socio-cultural acceptability in Iran has been investigated. To collect the data, the access to Iranmedex website, the premier medical data center in Iran, was made possible using the related keywords. The obtained data indicate whereas there is an increase in the number of organ donations from cadaver, it is still low in comparison to other countries. The lack of consent from families of brain-dead patients is a major hurdle on the way of organ transplantation in Iran. In the cases of willingness to donate organs, the major effective factors were the deceaseds religious beliefs and prior tendency. In 66 % of the cases, the donors families deemed organ donation phenomenon effective in alleviating the sorrow after the death of their beloved ones. The number of organ donation from cadaver in Iran is low contrary to other countries. It seems that general instructions to raise the knowledge on the subject and lay the foundation to increase the tendency towards posthumous organ donation are necessary.

Stereotactic Radiotherapy for Adrenal Gland Metastases: University of Florence Experience  

Science Conference Proceedings (OSTI)

Purpose: To evaluate a retrospective single-institution outcome after hypofractionated stereotactic body radiotherapy (SBRT) for adrenal metastases. Methods and Materials: Between February 2002 and December 2009, we treated 48 patients with SBRT for adrenal metastases. The median age of the patient population was 62.7 years (range, 43-77 years). In the majority of patients, the prescription dose was 36 Gy in 3 fractions (70% isodose, 17.14 Gy per fraction at the isocenter). Eight patients were treated with single-fraction stereotactic radiosurgery and forty patients with multi-fraction stereotactic radiotherapy. Results: Overall, the series of patients was followed up for a median of 16.2 months (range, 3-63 months). At the time of analysis, 20 patients were alive and 28 patients were dead. The 1- and 2-year actuarial overall survival rates were 39.7% and 14.5%, respectively. We recorded 48 distant failures and 2 local failures, with a median interval to local failure of 4.9 months. The actuarial 1-year disease control rate was 9%; the actuarial 1- and 2-year local control rate was 90%. Conclusion: Our retrospective study indicated that SBRT for the treatment of adrenal metastases represents a safe and effective option with a control rate of 90% at 2 years.

Re DSM: Here comes demand-side marketing  

SciTech Connect

Demand-side management (DSM) programs where utilities pay large rebates for energy efficient equipment are being declared dead. The popular view of DSM in the past was to encourage conservation of energy with significant rebates, credits and other incentives offered by electric and also natural gas utilities. After years of increase in utility DSM expenditures, the first decline took place last year of about 6% for the electric industry. Although still spending more than $2 billion in 1994, utilities have continued this year to reduce the number of DSM programs. For some utilities there has been a dramatic abandonment of energy efficiency incentive programs. Where programs remain, utilities are placing increased emphasis on the most cost-effective ones which are usually directed toward commercial and industrial facilities. At the same time utilities have been transforming their programs from demand-side management to demand-side marketing. The objectives have shifted to retaining existing customers, developing new accounts, and increasing profitable sales. Incentives are justified in this new cost-driven competitive environment when they result in decreased rates for all customers. Whereas, in the past, DSM program participants were the primary beneficiaries with reduced bills, in the new marketing environment all customers can benefit from reduced bills.

Factors controlling pathogen destruction during anaerobic digestion of biowastes  

SciTech Connect

Anaerobic digestion is the principal method of stabilising biosolids from urban wastewater treatment in the UK, and it also has application for the treatment of other types of biowaste. Increasing awareness of the potential risks to human and animal health from environmental sources of pathogens has focused attention on the efficacy of waste treatment processes at destroying pathogenic microorganisms in biowastes recycled to agricultural land. The degree of disinfection achieved by a particular anaerobic digester is influenced by a variety of interacting operational variables and conditions, which can often deviate from the ideal. Experimental investigations demonstrate that Escherichia coli and Salmonella spp. are not damaged by mesophilic temperatures, whereas rapid inactivation occurs by thermophilic digestion. A hydraulic, biokinetic and thermodynamic model of pathogen inactivation during anaerobic digestion showed that a 2 log{sub 10} reduction in E. coli (the minimum removal required for agricultural use of conventionally treated biosolids) is likely to challenge most conventional mesophilic digesters, unless strict maintenance and management practices are adopted to minimise dead zones and by-pass flow. Efficient mixing and organic matter stabilisation are the main factors controlling the rate of inactivation under mesophilic conditions and not a direct effect of temperature per se on pathogenic organisms.

Combustion characteristics and influential factors of isooctane active-thermal atmosphere combustion assisted by two-stage reaction of n-heptane  

Science Conference Proceedings (OSTI)

This paper presents an experimental study on the isooctane active-thermal atmosphere combustion (ATAC) which is assisted by two-stage reaction of n-heptane. The active-thermal atmosphere is created by low- and high-temperature reactions of n-heptane which is injected at intake port, and isooctane is directly injected into combustion chamber near the top dead center. The effects of isooctane injection timing, active-thermal atmosphere intensity, overall equivalence ratio, and premixed ratio on combustion characteristics and emissions are investigated. The experimental results reveal that, the isooctane ignition and combustion can be classified to thermal atmosphere combustion, active atmosphere combustion, and active-thermal atmosphere combustion respectively according to the extent of n-heptane oxidation as well as effects of isooctane quenching and charge cooling. n-Heptane equivalence ratio, isooctane equivalence ratio and isooctane delivery advance angle are major control parameters. In one combustion cycle, the isooctane ignited and burned after those of n-heptane, and then this combustion phenomenon can also be named as dual-fuel sequential combustion (DFSC). The ignition timing of the overall combustion event is mainly determined by n-heptane equivalence ratio and can be controlled in flexibility by simultaneously adjusting isooctane equivalence ratio. The isooctane ignition regime, overall thermal efficiency, and NO{sub x} emissions show strong sensitivity to the fuel delivery advance angle between 20 CA BTDC and 25 CA BTDC. (author)

The development of a versatile field program for measuring tritium in real-time  

Science Conference Proceedings (OSTI)

Robust sample handling and liquid scintillation counting procedures have been developed to routinely monitor tritium in the field relative to the 20,000 pCi/L drinking water standard. This procedure allows tritium to be monitored hourly during 24 hour drilling operations at depths in the saturated zone potentially contaminated by sub-surface nuclear weapons testing at the Nevada Test Site. Using retrofitted shock hardened and vibration damped counters and strict analytical protocols, tritium may be measured rapidly in the field under hostile conditions. Concentration standards and ``dead`` tritium backgrounds are prepared weekly in a central laboratory and delivered to remote monitoring locations where they are recounted daily as a check on counter efficiency and calibration. Portable counters are located in trailers and powered off a battery pack and line filter fed by mobile generator. Samples are typically ground-waters mixed with drilling fluids returned after circulation through a drill string. Fluids are aerated and ``de-foamed,`` filtered, mixed with scintillation cocktail and subsequently dark-adapted before counting. Besides meeting regulatory requirements, ``real-time`` monitoring affords drilling and field personnel maximum protection against potential exposure to radionuclides; for routine operations, tritium activities may not exceed a 10,000 pCi/L threshold.

Fossil AGN jets as ultra high energy particle accelerators  

E-Print Network (OSTI)

Remnants of AGN jets and their surrounding cocoons leave colossal magnetohydrodynamic (MHD) fossil structures storing total energies ~10^{60} erg. The original active galacic nucleus (AGN) may be dead but the fossil will retain its stable configuration resembling the reversed-field pinch (RFP) encountered in laboratory MHD experiments. In an RFP the longitudinal magnetic field changes direction at a critical distance from the axis, leading to magnetic re-connection there, and to slow decay of the large-scale RFP field. We show that this field decay induces large-scale electric fields which can accelerate cosmic rays with an E^{-2} power-law up to ultra-high energies with a cut-off depending on the fossil parameters. The cut-off is expected to be rigidity dependent, implying the observed composition would change from light to heavy close to the cut-off if one or two nearby AGN fossils dominate. Given that several percent of the universe's volume may house such slowly decaying structures, these fossils may even...

Fate of pathogens in a simulated bioreduction system for livestock carcasses  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer Bioreduction is a novel on-farm storage option for livestock carcasses. Black-Right-Pointing-Pointer Legislation demands that pathogens are contained and do not proliferate during carcass storage. Black-Right-Pointing-Pointer We examined the survival of key pathogens in lab-scale bioreduction vessels. Black-Right-Pointing-Pointer Pathogen numbers reduced in the resulting liquor waste and bioaerosols. Black-Right-Pointing-Pointer The results indicate that bioreduction should be validated for industry use. - Abstract: The EU Animal By-Products Regulations generated the need for novel methods of storage and disposal of dead livestock. Bioreduction prior to rendering or incineration has been proposed as a practical and potentially cost-effective method; however, its biosecurity characteristics need to be elucidated. To address this, Salmonella enterica (serovars Senftenberg and Poona), Enterococcus faecalis, Campylobacter jejuni, Campylobacter coli and a lux-marked strain of Escherichia coli O157 were inoculated into laboratory-scale bioreduction vessels containing sheep carcass constituents. Numbers of all pathogens and the metabolic activity of E. coli O157 decreased significantly within the liquor waste over time, and only E. faecalis remained detectable after 3 months. Only very low numbers of Salmonella spp. and E. faecalis were detected in bioaerosols, and only at initial stages of the trial. These results further indicate that bioreduction represents a suitable method of storing and reducing the volume of livestock carcasses prior to ultimate disposal.

Digital multimode buck converter control with loss-minimizing synchronous rectifier adaptation  

E-Print Network (OSTI)

AbstractThis paper develops a multimode control strategy which allows for efficient operation of the buck converter over a wide load range. A method for control of synchronous rectifiers as a direct function of the load current is introduced [1]. The function relating the synchronous-rectifier timing to the load current is optimized on-line with a gradient power-loss-minimizing algorithm. Only low-bandwidth measurements of the load current and a power-loss-related quantity are required, making the technique suitable for digital controller implementations. Compared to alternative loss-minimizing approaches, this method has superior adjustment speed and robustness to disturbances, and can simultaneously optimize multiple parameters. The proposed synchronous-rectifier control also accomplishes an automatic, optimal transition to discontinuous-conduction mode at light load. Further, by imposing a minimum duty-ratio, the converter automatically enters pulse-skipping mode at very light load. Thus, the same controller structure can be used in both fixed-frequency pulsewidth modulation and variable-frequency pulse-skipping modes. These techniques are demonstrated on a digitally-controlled 100-W buck converter.

Magnitude and Dynamics of Predation on Juvenile Salmonids in Columbia and Snake River Reservoirs, Annual Report of Research, 1989-1990.  

SciTech Connect

Three aspects of predation upon juvenile salmonids in the Columbia River are addressed in this report: (1) Indexing predator consumption. During 1989--1990, two indices of northern squawfish consumption upon juvenile salmonids were developed for use throughout the Columbia River Basin. The direct Consumption Index (CI) is based upon the concept of meal turnover time and takes into account number of salmonids, temperature, total gut content weight and predator weight. A Bioenergetics Index (BI) for consumption indexing was also developed to complement the direct CI. In the BI, growth, consumption, excretion/evacuation and respiration processes are modeled to predict the consumption required to produce an observed growth increment. (2) Studies on predator-smolt dynamics. Northern squawfish consumption data were collected in the McNary Dam tailrace during nine days in July 1988 to improve our understanding of the predator-smolt functional response. (3) Selective predation by northern squawfish. Laboratory and field protocols were developed to evaluate northern squawfish selection and prey vulnerability. Results from laboratory studies suggest that northern squawfish prefer dead over live prey and that descaled prey may be more vulnerable to predation than non-descaled prey. Stressed and unstressed prey were consumed in equal proportions when predation occurred for 6 or 24 h. Physiological and behavioral effects of stress on juvenile salmon are presented. 100 refs., 13 figs., 12 tabs.

Automated coregistration of MTI spectral bands.  

SciTech Connect

In the focal plane of a pushbroom imager, a linear array of pixels is scanned across the scene, building up the image one row at a time. For the Multispectral Thermal Imager (MTI), each of fifteen different spectral bands has its own linear array. These arrays are pushed across the scene together, but since each band's array is at a different position on the focal plane, a separate image is produced for each band. The standard MTI data products resample these separate images to a common grid and produce coregistered multispectral image cubes. The coregistration software employs a direct 'dead reckoning' approach. Every pixel in the calibrated image is mapped to an absolute position on the surface of the earth, and these are resampled to produce an undistorted coregistered image of the scene. To do this requires extensive information regarding the satellite position and pointing as a function of time, the precise configuration of the focal plane, and the distortion due to the optics. These must be combined with knowledge about the position and altitude of the target on the rotating ellipsoidal earth. We will discuss the direct approach to MTI coregistration, as well as more recent attempts to 'tweak' the precision of the band-to-band registration using correlations in the imagery itself.

Wave Propagation and Damage Characterization in Natural Fiber Hemp and LLDPE Composite  

E-Print Network (OSTI)

Research in incorporating natural fibers in composites has been in progress for a few decades where the various mechanical, electrical and acoustic properties of such composites were explored. Natural fiber composites (NFCs) have few benefits over the traditional glass or carbon fiber composites such as light weight, low manufacturing cost and requiring less energy for production. NFC is also bio-degradable and recyclable. The primary objectives of this research are to explore the static and dynamic properties of the hemp and linear low density polyethylene (LLDPE) and determine impact absorbing capability using the above mentioned properties. LLDPE is surface-treated with maleic anhydride grafted polyethylene (MA-g-PE) and sodium hydroxide (NaOH). A melt-mixing process is employed where LLDPE is compounded with the hemp fibers in 10%, 20% and 30% vol. fraction. Tensile and flexural properties are measured. The material is characterized by propagating Lamb waves generated using a dropped dead weight. Time-frequency information is extracted from a thin disc-like specimen using the Gabor Wavelet Transform (GWT) so as to characterize the material. Detection of defect is also established using the generated waves and GWT. Using Gabor wavelet coefficients, the dispersion and attenuation of the specimen are determined in different material directions. Comparison of attenuation of the waveforms is observed at different locations providing the knowledge of materials homogeneity, the materials behavior due to an impact and its impact absorbing character.

Emerging Technologies and MOUT  

SciTech Connect

Operating in a potentially hostile city is every soldier's nightmare. The staggering complexity of the urban environment means that deadly threats--or non-combatants-may lurk behind every corner, doorway, or window. Urban operations present an almost unparalleled challenge to the modern professional military. The complexity of urban operations is further amplified by the diversity of missions that the military will be called upon to conduct in urban terrain. Peace-making and peace-keeping missions, urban raids to seize airports or WMD sites or to rescue hostages, and extended urban combat operations all present different sorts of challenges for planners and troops on the ground. Technology almost never serves as a magic bullet, and past predictions of technological miracles pile high on the ash heap of history. At the same time, it is a vital element of planning in the modern age to consider and, if possible, take advantage of emerging technologies. We believe that technologies can assist military operations in urbanized terrain (MOUT) in three primary areas, which are discussed.

Black Hole Firewalls Require Huge Energy of Measurement  

E-Print Network (OSTI)

The unitary moving mirror model is one of the best quantum systems for checking the reasoning of the firewall paradox in quantum black holes. Though the late-time part of radiations emitted from the mirror is fully entangled with the early-part, no AMPS's firewall exists with a deadly, huge average energy flux in this model. This is because high-energy entanglement structure of the discretized systems in almost maximally entangled states is modified so as to yield the correct description of low-energy effective field theory. Due to the Reeh-Schlieder theorem in quantum field theory, another firewall paradox is inevitably raised with quantum remote measurements in the model. We resolve this paradox from the viewpoint of the energy cost of measurements. No firewall appears, as long as the energy for the measurement is much smaller than the ultraviolet cutoff scale. Furthermore, the strong subadditivity paradox of firewalls is resolved using non-locality of general one-particle states and zero-point fluctuation entanglement.

Nuclear electricity is the least-cost option  

SciTech Connect

The use of integrated resource planning (IRP) as a tool for selecting the means to satisfy the need for new electricity heavily favors those options that are evaluated to have the least cost. The least-cost option these days, generally combined cycle burning natural gas, can generate electricity for between 3.5 to 4.0 {cents}/kW {times} h. The average generating cost of nuclear electricity, by comparison, is {approximately} 7.0 {cents}/kW {times} h, indicative of the economic challenge facing the nuclear industry. The future for the nuclear option may be better, if you believe that natural gas prices will increase. Studies by General Electric (GE) show that if these prices escalate at 3.5% above inflation, as DRI and others forecast, advanced nuclear plants will be in an economic dead heat with coal and combined-cycle/natural-gas plants, the primary baseload options. The use of environmental externalities can also change the evaluation of these competing technology options. When the cost of pollution emissions from fossil plants are factored in, studies show that nuclear electricity generation is the best economic option.

Leak Pruning  

E-Print Network (OSTI)

Managed languages improve programmer productivity with type safety and garbage collection, which eliminate memory errors such as dangling pointers, double frees, and buffer overflows. However, programs may still leak memory if programmers forget to eliminate the last reference to an object that will not be used again. Leaks slow programs by increasing collector workload and frequency. Growing leaks crash programs. Instead of crashing, leak pruning extends program availability by predicting and reclaiming leaked objects at run time. Whereas garbage collection over-approximates live objects using reachability, leak pruning predicts dead objects and reclaims them based on how stale they are and the size of stale data structures. Leak pruning preserves semantics because it waits for heap exhaustion before reclaiming objects and then poisons references to objects it reclaims. If the program later tries to access these objects, the virtual machine (VM) throws an internal error. We implement leak pruning in a Java VM, show its overhead is low, and evaluate it on 10 leaking programs. Leak pruning does not help two programs, executes four substantial programs 1.6-35X longer, and executes four programs, including two leaks in Eclipse, for at least 24 hours. In the worst case, leak pruning defers fatal errors. In the best case, programs with unbounded memory requirements execute indefinitely and correctly in bounded memory with consistent throughput.

Liquid chromatography/Fourier transform IR spectrometry interface flow cell  

DOE Patents (OSTI)

A zero dead volume (ZDV) microbore high performance liquid chromatography (.mu.HPLC)/Fourier transform infrared (FTIR) interface flow cell includes an IR transparent crystal having a small diameter bore therein through which a sample liquid is passed. The interface flow cell further includes a metal holder in combination with a pair of inner, compressible seals for directly coupling the thus configured spectrometric flow cell to the outlet of a .mu.HPLC column end fitting to minimize the transfer volume of the effluents exiting the .mu.HPLC column which exhibit excellent flow characteristics due to the essentially unencumbered, open-flow design. The IR beam passes transverse to the sample flow through the circular bore within the IR transparent crystal, which is preferably comprised of potassium bromide (KBr) or calcium fluoride (CaF.sub.2), so as to minimize interference patterns and vignetting encountered in conventional parallel-plate IR cells. The long IR beam pathlength and lensing effect of the circular cross-section
