Chromogravity explains {open_quotes}strong gravity{close_quotes}  

SciTech Connect

In this paper the authors deal with the question of gravitational type interactions in the case of strong interaction phenomena. They present arguments which indicate that it is not necessary to invoke a gravity type interaction into QCD in order to account for observed phenomena. They argue that the gravitational type phenomena discussed in previous work is a manifestation of a class of Feynmann diagrams. These seem to generate an analog to gravity, a J=2 {open_quotes}chromograviton{close_quotes} or {open_quotes}pseudo-graviton{close_quotes} whose action effectively generates Salam`s {open_quotes}Strong Gravity{close_quotes} or {open_quotes}f-gravity{close_quotes}, withthough having to introduce the theory as an additional input.

Inference in {open_quotes}poor{close_quotes} languages  

SciTech Connect

Languages with a solvable implication problem but without complete and consistent systems of inference rules ({open_quote}poor{close_quote} languages) are considered. The problem of existence of a finite, complete, and consistent inference rule system for a {open_quotes}poor{close_quotes} language is stated independently of the language or the rule syntax. Several properties of the problem are proved. An application of the results to the language of join dependencies is given.

MR {open_quotes}hot nose sign{close_quotes} and {open_quotes}intravascular enhancement sign{close_quotes} in brain death  

SciTech Connect

Three cases of MR with gadopentetate dimeglumine in patients diagnosed with cerebral death are presented. Observation of an MR {open_quotes}hot nose sign{close_quotes} and an {open_quotes}intravascular enhancement sign{close_quotes} provided additional imaging support in the clinical diagnosis of brain death. The MR findings in brain death include: (1) transtentorial and foramen magnum herniation, (2) absent intracranial vascular flow void, (3) poor gray matter/white matter differentiation, (4) no intracranial contrast enhancement, (5) carotid artery enhancement (intravascular enhancement sign), and (6) prominent nasal and scalp enhancement (MR hot nose sign). Additional modalities for confirming brain death are discussed. 41 refs., 2 figs.

{open_quotes}BIOX{close_quotes} hydrogen sulfide abatement process - application analysis  

SciTech Connect

A new hydrogen sulfide abatement process, known as {open_quotes}BIOX,{close_quotes} has been specifically developed for the geothermal industry. {open_quotes}BIOX{close_quotes} (biocide induced oxidation) successfully controls both primary and secondary emissions from cooling towers in pilot, demonstration, and commercial operations by air-wet oxidation. Independent laboratory tests recently controverted the efficacy of {open_quotes}BIOX{close_quotes} to catalytically oxidize sulfides to sulfate. Studies conducted in our laboratory with a simulated cooling tower indicate that the experimental conditions employed by Nardini, et al, are unrealistic for geothermal cooling towers. Furthermore, our investigations demonstrate that the {open_quotes}BIOX{close_quotes} process performs optimally at near neutral pH, a condition common to most geothermal cooling tower circulating water systems. A {open_quotes}BIOX{close_quotes} agent, trichloroisocyanuric acid (TCCA), proved to mitigate sulfide emissions much more efficiently than air, sodium hypochlorite or chlorine dioxide. {open_quotes}BIOX{close_quotes} is a proven, cost-effective H{sub 2}S abatement technology.

Dispersion morphology diagrams for three-phase, [open quotes]microemulsion[close quotes] emulsions. 2. [open quotes]Disappearance[close quotes] of morphology-transition lines  

SciTech Connect

The limits over which the oil-rich top phase (T), middle-phase microemulsion (M), or water-rich bottom phase (B) is the continuous phase in steady-state, three-phase macroemulsions have been determined by means of electrical conductivity measurements for the amphiphile/oil/[open quotes]water[close quotes] system C[sub 6]H[sub 13](OC[sub 2]H[sub 4])[sub 2]OH/n-tetradecane/aqueous 10 mM NaCl. Measurements were made at three different temperatures and apparent wettability conditions: (a) 45[degrees]C, wetting middle phase; (b) 25[degrees]C, no wetting phase; and (c) 12[degrees]C, wetting bottom phase. The results at 25[degrees]C were in accord with expectations from previous predictions and experiments; but for both two-phase and three-phase emulsions no abrupt, [open quotes]first-order[close quotes] transitions between M- and T-continuous emulsions at 45[degrees]C or between M- and B-continuous emulsions at 12[degrees]C were found. Instead, these changes of continuous phase appeared to occur smoothly and continuously between their respective single-phase and two-phase limits. It is not yet clear if the [open quotes]disappearance[close quotes] of first-order morphology transitions correlates with phase wettability transitions; the phenomenon suggests the possibility of bicontinuous two-phase and three-phase macroemulsions. 31 refs., 11 figs.

Nonabelian Debye screening and the {open_quotes}tsunami{close_quotes} problem  

SciTech Connect

The phenomenon of Debye screening is familiar from electrolytes and many other systems. Recently, it has been recognized that in nonabelian gauge theories at high temperature, even perturbatively Debye screening is much more complicated than in nonrelativistic systems. This was originally derived as {open_quotes}hard thermal loops{close_quotes}. Hard thermal loops have been derived perturbatively, by a semiclassical truncation of the Schwinger-Dyson equations, and by classical kinetic theory. In this talk I give a pedagogical derivation, following that of Kelly, Liu, Lucchesi, and Manuel. The derivation is valid not just for a thermal distribution, but (modulo certain obvious restrictions) for an arbitrary initial distribution of particles. Consider, for example, the {open_quotes}tsunami{close_quotes} problem: suppose that one starts, at time t = 0, with a spatially homogenous, infinite wall of particles, all moving with the same velocity at the speed of light.

Greenland ice core {open_quotes}signal{close_quotes} characteristics: An expanded view of climate change  

SciTech Connect

The last millenium of Earth history is of particular interest because it documents the environmental complexities of both natural variability and anthropogenic activity. The authors have analyzed the major ions contained in the Greenland Ice Sheet Project 2 (GISP 2) ice core from the present to {approximately}674 A.D. to yield an environmental reconstruction for this period that includes a description of nitrogen and sulfur cycling, volcanic emissions, sea salt and terrestrial influences. They have adapted and extended mathematical procedures for extracting sporadic (e.g., volcanic) events, secular trends, and periodicities found in the data sets. Finally, by not assuming that periodic components (signals) were {open_quotes}stationary{close_quotes} and by utilizing evolutionary spectral analysis, they were able to reveal periodic processes in the climate system which change in frequency, {open_quotes}turn on,{close_quotes} and {open_quotes}turn off{close_quotes} with other climate transitions such as that between the little ice age and the medieval warm period. 42 refs., 4 figs., 2 tabs.

Specific heat and transport {open_quotes}anomalies{close_quotes} in mixed alkali glasses  

SciTech Connect

We show that changes in the relative mole fractions of Li{sub 2}O and Na{sub 2}O in alkali metaphosphate glasses lead to {open_quotes}anomalies{close_quotes} in the specific heat and structural relaxations. The heat capacity change between the liquid and glassy states, {Delta}c{sub p}(T{sub g}), at the calorimetric glass transition temperature, T{sub g}, exhibits a minimum when the mole fractions of Li{sub 2}O and Na{sub 2}O are comparable. Moreover, systematic changes in the temperature dependence of the viscosity, {eta}, i.e., changes in the {open_quotes}fragility{close_quotes} of the system, accompany these changes in mole fraction. This observed dependence of the {open_quotes}fragility{close_quotes} on the mixed alkali ion composition occurs in the absence of apparent changes in the covalent network connectivity which normally accounts for this behavior in glasses. {copyright} {ital 1998 American Institute of Physics.}

{open_quotes}Shift-Betel{close_quotes}: A (very) distributed mainframe  

SciTech Connect

Over the last four years, CERN has progressively converted its central batch production facilities from classic mainframe platforms (Cray XMP, IBM, ESA, Vax 9000) to distributed RISC based facilities, which have now attained a very large size. Both a CPU-intensive system ({open_quotes}CSF{close_quotes}, the Central Simulation Facility) and an I/O-intensive system ({open_quotes}SHIFT{close_quotes}, the Scaleable Heterogeneous Integrated Facility) have been developed, plus a distributed data management subsystem allowing seamless access to CERN`S central tape store and to large amounts of economical disk space. The full system is known as {open_quotes}CORE{close_quotes}, the Centrally Operated Risc Environment; at the time of writing CORE comprises around 2000 CERN Units of Computing (about 8000 MIPs) and over a TeraByte of online disk space. This distributed system is connected using standard networking technologies (IP protocols over Ethernet, FDDI and UltraNet), but which until quite recently were only implemented at sufficiently high speed in the Local Area.

Comment on [open quotes]Nonlocality, counterfactuals, and quantum mechanics[close quotes  

SciTech Connect

A recent proof [H. P. Stapp, Am. J. Phys. [bold 65], 300 (1997)], formulated in the symbolic language of modal logic, claims to show that contemporary quantum theory, viewed as a set of rules that allow us to calculate statistical predictions among certain kinds of observations, cannot be imbedded in any rational framework that conforms to the principles that (1) the experimenters[close quote] choices of which experiments they will perform can be considered to be free choices, (2) outcomes of measurements are unique, and (3) the free choices just mentioned have no backward-in-time effects of any kind. This claim is similar to Bell[close quote]s theorem, but much stronger, because no reality assumption alien to quantum philosophy is used. The paper being commented on [W. Unruh, Phys. Rev. A [bold 59], 126 (1999)] argues that some such reality assumption has been [open quotes]smuggled[close quotes] in. That argument is examined here and shown, I believe, to be defective.

The magnetron {open_quotes}threshold voltage{close_quotes} revisited  

SciTech Connect

In view of the revival of interest in high-power magnetrons, an important magnetron parameter called the {ital threshold voltage} has been rederived for both relativistic and nonrelativistic cases using a novel and simplified approach. The main purpose of the paper is to investigate the physical significance of the threshold voltage and to show that, contrary to a long established opinion, no restriction on the amplitude of oscillations is required. In fact, the name itself is a misnomer, since in practice the threshold voltage is an approximate dc anode voltage at which the tube operates when delivering {ital full power}. It is this feature which, in our opinion, makes the threshold voltage so important and useful in practice. A set of numerical computations confirms our analysis and also reveals a form of Lorenz{close_quote}s {open_quotes}butterfly effect{close_quotes} associated with the perceived start of oscillations. {copyright} {ital 1997 American Institute of Physics.}

The physical properties of alloys in the liquid and {open_quotes}mushy{close_quotes} states

Data on the physical properties of alloys at high temperatures are urgently needed for the mathematical modeling of high-temperature processes such as casting, welding, secondary refining, dip melting, spray forming, and metal powder production. Data are required for those properties which are involved in heat and fluid flow in high-temperature processes. Levitated drop methods have been adopted to measure the surface tensions, densities, and enthalpies of commercial alloys, and rapid, transient methods have been developed to measure thermal conductivities to avoid the problem of convection. The results obtained for the properties of commercial alloys for the liquid and {open_quotes}mushy{close_quotes} states are discussed.

{open_quotes}Unbounded{close_quotes} second order partial differential equations in infinite dimensional Hilbert spaces  

SciTech Connect

In this paper we study fully nonlinear stationary partial differential equations. Where H is a real, separable Hilbert space, A is a linear, densely defined, maximal monotone operator on H and {mu} is a real valued function. Above Du(x) and D{sup 2}u(x) correspond respectively to the first and second order Frechet derivatives of {mu}. Identifying H with its dual, Du(x) corresponds to an element of H and D{sup 2}{mu}(x) to an element of S(H), the space of bounded, self-adjoint operators on H. Equations and initial value problems are of importance since they appear as the dynamic programming equations associated with problems of stochastic optimal control if one controls an infinite dimensional system governed by a stochastic PDE. We call then {open_quotes}unbounded{close_quotes} because of the term (Ax,Du) which is not defined everywhere and is not locally bounded. This forces us to interpret the equations in the proper viscosity sense, in particular the above mentioned term must be given special treatment. {open_quotes}Unboundedness{close_quotes} in dynamic programming equations arises for instance when state equations of systems involve unbounded operators.

The dolomitized{open_quotes}O{close_quotes} Limestone in the Barinas basin: A hydrocarbon reservoir in carbonate rocks  

SciTech Connect

The {open_quotes}O{close_quotes} Limestone Member, top of Escandalosa Formation of a Lower to Upper Cretaceous age, is an interval of about 70 feet thick. It represents a coastal facies of caitonate platform; dominated by carbonates of calcarenitic lithologies intercalated with some sandy, glauconitic, calcareous bodies and thin bioturbated shaly intervals. Detailed studies carried out in five cores yield to a new approach and subdivision within this interval based on diagnostic erosive surfaces that may be interpreted as sequence boundaries. Based on sedimentology, trace fossil assemblages and diagenetic events, the milieu of sedimentation varies from foreshore to offshore. Porous dolomite levels occur within the {open_quotes}O{close_quotes} Limestone. This porosity is of intergranular, moldic and vuggy types. Some microfractures are also observed. Subaerial karstification is an alternative hypothesis that can explain the origin of the localized dolomitized vuggy reservoirs. The following sequence of events is suggested: (1) Sedimentation followed by bioturbation, then lithification with a probable replacement of aragonite by calcite, (2) Early dolomitization undergoing the {open_quotes}mixing{close_quote} or {open_quotes}Dorag {close_quotes} Model, (3) Dedolomitization and dissolution generating a moldic porosity enhanced the vuggy forms. This stage may have been influenced by karst processes, (4) Burial diagenesis accompanied by stylolitization and fracturation with pressure-solution effects, and (5) Some levels increase their porosity because of partial dolomitization; in others the vuggy porosity is totally infilled with sparry calcite.

The primary objective of this {open_quotes}CAT{close_quotes} project is to complete a conceptual design of this unique new combination of existing technology with cost estimates to show that the {open_quotes}CAT{close_quotes} system offers the economic incentive with low technical risk for a plant to be built which will demonstrate its viability. The technologies involved in the components of a {open_quotes}CAT{close_quotes} plant are proven, and the integration of the components into a complete plant is the only new development activity involved. Industry and the Federal General Services Administration (GSA), require the demonstration of a {open_quotes}commercial plant{close_quotes} before the viability of a new concept is accepted. To satisfy this requirement and construction of a plant of commercially viable size in excess of 15 MW if cogeneration and above 30 MW if all power, is proposed. This plant will produce economical power and heat for the owner. The plant will operate a full commercial life and continue as an operating demonstration of the viability of the technology, gathering long term life and maintenance data, all adding to the credibility of the concept.

Mapping the human genome by using {open_quotes}whole genome{close_quotes} radiation hybrids  

SciTech Connect

An important goal of the Human Genome Project is to construct a map of the human genome at an average resolution of 100 kilobases (kb), which should provide the scientific community with a valuable resource for the localization an isolation of any human DNA sequence of interest. In an effort to complete this map by the projected date of 1998, we have constructed two sets of {open_quotes}whole genome{close_quotes} radiation hybrids. The first set of 83 hamster-human somatic cell hybrids contains human DNA fragments approximately 5 million base pairs in length. Each individual hybrid cell line contains approximately one fifth of the entire human genome. Our mapping results indicate that these whole genome radiation hybrids represent an important resource for constructing the 100 kb map in a timely and cost-effective fashion.

The economics of conserved-energy {open_quotes}supply{close_quotes} curves  

SciTech Connect

This paper develops the theoretical underpinnings of conservation {open_quotes}supply{close_quotes} curves (CSCs), and in doing so uncovers several problem with current procedures for their construction. The CSC is shown to be derivable from a production isoquant, and not to be a true supply curve. The traditional algorithm for constructing a CSC from discrete measures is shown to be suboptimal, contrary toprior claims. Omitting conservation measures from consideration can lead to systematic, excessive conservation. The CSC concept is extended from constant-service to constant-utility measures, and an improved approximation is suggested for the cost of conserved energy (CCE) of measures that cause rebound. The appendix provides a formula for CCE that is simple yet more general than the one currently in use, but shows that even with this generalization, CSCs cannot be constructed for a world with fluctuating energy prices. 24 refs., 10 figs.

Synonymous nucleotide divergence: What is {open_quotes}saturation{close_quotes}?  

SciTech Connect

The nucleotide divergence at synonymous third sites between two lineages will increase with time since the latest common ancestor, up to some saturation level. The {open_quotes}null-hypothesis divergence{close_quotes} is defined as the percentage of difference predicted at synonymous third sites, allowing for amino acid composition and codon bias, but assuming that codon bias is the same at all sites occupied by a given amino acid, when equilibrium has been reached between forward and backward substitutions. For two highly expressed genes, gapA and ompA, in the enterobacteria, the estimated values of the null-hypothesis divergence are 39.3 and 38.15%, respectively, compared to estimated values of saturation divergence of 19.0 and 25.4%. A possible explanation for this discrepancy is that different codons for a given amino acid are favored at different sites in the same gene. 5 refs., 2 figs.

{open_quotes}Quadrupoled{close_quotes} materials for second-order nonlinear optics  

SciTech Connect

We describe a new approach to second-order nonlinear optical materials, namely quadrupoling. This approach is valid in the regime of Kleinman (full permutation) symmetry breaking, and thus requires a two- or three dimensional microscopic nonlinearity at wavelengths away from material resonances. This {open_quotes}quadrupolar{close_quotes} nonlinearity arises from the second rank pseudotensor of the rotationally invariant representation of the second-order nonlinear optical tensor. We have experimentally investigated candidate molecules comprised of chiral camphorquinone derivatives by measuring the scalar invariant associated with the rank two pseudotensor using hyper-Rayleigh scattering. We have found sizable scalar figures of merit for several compounds using light for which the second harmonic wavelengths are greater than 100 nm longer than the absorption peak location. At these wavelengths, the quadrupolar scalar is as large as the polar (EFISH) scalar of p-nitroaniline. Prospects for applications are discussed.

Agriculture and the recent [open quotes]Benign Climate[close quotes] in Minnesota  

SciTech Connect

This work provides data supporting a little noticed but remarkably consistent and agriculturally favorable climatic period existed for approximately 18 years, beginning in the mid-1950s in the US Corn Belt and perhaps even earlier in Minnesota. The full application of technology to agriculture was delayed due to world political events (World War II and the Korean conflict, for example) until the 1950s. It is concluded that from then until about 1974, the interaction between this favorable climatic period and the applied technology and the enthusiasm they engendered in agricultural circles were subtle and unrealized factors that helped lead to the agricultural inflation of the 1970s, while the unexpected and generally unrecognized cessation of the [open quotes]benign[close quotes] climate must be considered as a factor leading to the agricultural depression in the 1980s. 17 refs., 10 figs.

Salvaging dipmeters using an oil field {open_quotes}Dinosaur{close_quotes}  

SciTech Connect

Although state-of-the-art methods such as 3-D seismic and formation imaging tools are widely used, the advantages of the old standard dipmeter should not be dismissed. Seismic dip is subject to velocity errors, and formation imagers cannot be run in all borehole conditions. The dipmeter offers a relatively low cost, highly effective alternative for defining geologic features. The 60{double_prime}= 100{prime} scale playback of the raw dipmeter data may be an oil field {open_quotes}dinosaur,{close_quotes} but it is also the key to assessing the reliability of a dipmeter. This playback should be used to determine CORRELATION QUALITY, critical to the accuracy of any dipmeter. Computer computation of the raw dipmeter data does not always yield reliable dip information, particularly when dipmeters are run under adverse hole conditions or in complex geology. This data can be often salvaged by optical correlation of the 60{close_quote} playback - the process of manually correlating raw dipmeter resistivity curves to determine the attitude of bedding planes in the subsurface. Problems such as tool noise, tool pulls, and poor pad contact compromise data quality. These problems can be recognized and compensated for using optical correlation. Finally, at the 60{double_prime} scale many formation textures and structural characteristics visible on the formation imaging logs are also discernible on the standard dipmeter traces. We will offer many Gulf Coast examples and some hands-on demonstrations using the 60{double_prime} data, and show improved tadpole plots which result from optical correlation.

Myth-building: The [open quotes]Islamic[close quotes] bomb  

SciTech Connect

The [open quotes]Islamic Bomb[close quotes] is roughly understood to be a nuclear weapon aquired for broad ideological reasons--a weapon that supposedly belongs to the Muslim [ital ummah] or community and, as such, is the ultimate expression of Islamic solidarity. Concern about the Islamic bomb is at the heart of the intense effort to prevent the spread of nuclear weapons to Muslim countries. The official justification is a general one: proliferation must be curbed globally. But unofficially, the Islamic bomb gets special attention. The reasons behind this special attention are described in this article. The reasons include fear of terrorism, of a [ital jihad] willing to indiscriminately use nuclear weapons in hope of a reward in the Hereafter, and of the transfer of nuclear arms from nuclear to non-nuclear Muslim countries in times of crisis. Possibilities for controlling the proliferation of nuclear weapons in Muslim countries are addressed. Reasons are cited as to why various Muslim countries wish to acquire nuclear weapons.

[open quote]Endangered[close quote] salmon: More than just a Northwest hydro problem  

SciTech Connect

In the US, about 600 species of plants and animals are considered threatened or endangered under the Endangered Species Act. One of those, the Snake River sockeye salmon, has been making news in the Pacific Northwest. In November 1991, the National Marine Fisheries Service (NMFS) declared Snake River sockeye salmon an endangered species, mandating the creation of a recovery plan that could cost more than $70 million a year. Many in the Northwest believe that the Endangered Species Act has never been applied in a case affecting so large an area or such a wide range of economic interests, including hydropower, agriculture, hatcheries, and commercial and sport fishing. Implications of this listing go far beyond regional economics, though. The way in which the federal government applied the Endangered Species Act in this instance has set a precedent that could affect hydro development throughout the US. The Endangered Species Act must be reauthorized by Congress by late October 1992. As explained in the accompanying story, [open quotes]Reauthorizing the ESA: Many Groups Calling for Change,[close quotes] the majority opinion in the US is that the act needs reform. Reviewing the act and its application in the Pacific Northwest will help members of the US hydro industry understand how hydro developments could be affected.

As part of a systematic study into {open_quotes}unspecific{close_quotes} XMR involving more than 30 non-FRAXA families, linkage studies have enabled us to map the respective genes in 4 families to the Xp11.4-q12 interval with peak lod scores around the ALAS2 locus. In three other families, the gene defect could be assigned to the KAL-DMD, DXS424-FRAXAC2 and DSX52-Xqter intervals, respectively. In one of these families, small stature due to growth hormone deficiency was observed as a distinctive clinical feature. Molecular cloning of the breakpoint in a mentally retarded girl with a balanced t(Xq13;13q) translocation has enabled us to isolate an X-chromosomal gene which is disrupted in this patient and is highly expressed in brain. YAC cloning strategies are being employed to clone another XMR gene, which has been identified previously in the vicinity of the CHM locus and genes involved in mentally retarded patients with two different inversions, inv(X)(q21p11) and inv(X)(p21q24), respectively.

Stored Guthrie cards as DNA [open quotes]Banks[close quotes  

SciTech Connect

Recently there has been much discussion about the possibility of using dried blood spots on Guthrie cards as a source of DNA for research or testing purposes. The collections of Guthrie cards stored by state newborn-screening laboratories can thus be viewed as inchoate [open quotes]DNA banks[close quotes]. This has generated concern among some persons who are interested in preserving the privacy of medical records. This study examines the policies of state newborn-screening laboratories in the United States, regarding their retention of Guthrie cards and the degree to which they permit the sharing of those cards with various third parties. The authors found that although most laboratories retain their cards, if at all, for only a short time, a growing number plan to keep them for an extended period-and, in several cases, indefinitely. They also found that although most laboratories would decline to release individually identifiable blood spots from the cards to third parties without a written release or other explicit authorization, a large number would at least consider sharing anonymous cards for research purposes. 10 refs., 2 tabs.

The restructuring and future of {open_quotes}Mendelian Inheritance in Man{close_quotes} (MIM)  

SciTech Connect

Victor McKusick`s catalog {open_quotes}Mendelian Inheritance in Man{close_quotes} represents the most comprehensive compendum of human genetic disease information available today and has appeared as a series in book form for the last 30 years. The 11th edition will contain almost 7000 entries: approximately 2800 descriptions of human genetic disorders, 700 combined disorder/gene descriptions and 3500 pure gene descriptions. Until recently the content of the catalogs was maintained solely by McKusick with a support staff. However, a distributed editing system has now been established with the following primary components. New entries are initiated in Baltimore by science writers under the guidance of the senior editors and McKusick, following which the information is made immediately available to the public through online access. The subject editors can then review and edit the new or modified information without impeding the timeliness of entering new information. Entries are being reconstructured so that clinical disorder and gene information is divided into separate entries which will better represent the frequently complex relationship of gene mutations to individual clinical disorders in the data files. Further, each entry is being subdivided into logical topics which will enhance the power of electronic searching, making links between topics and improving readability. The old division of entries into autosomal dominant and recessive, etc., is being abandoned in favor of clinical disorder (phenotypes) and gene catalogs. The information is maintained in an SGML format which facilitates the production of many different types of output varying from the traditional book form to CD ROMs and various online formats including IRx, WAIS, Gopher and World Wide Web. This latter offers the exciting possibility of making hypertext links between entries and other data resources, including photographic, sound and video clips as part of the total MIM information.

[open quotes]Passing the test[close quotes] - Human behavior and California's smog check program  

SciTech Connect

We have analyzed data obtained from more than 11,000 vehicles inspected in California's random roadside surveys to assess the real-world characteristics of the in-use motor vehicle fleet and to test the effectiveness of California's inspection and maintenance (I/M) program. The low-idle emissions data from these surveys show that 10 percent of the fleet are responsible for about 60 percent of the exhaust hydrocarbons and also that 10 percent of the fleet (not necessarily the same vehicles) are responsible for about 60 percent of the carbon monoxide emissions. We also show that high emitters appear among all model years, and not just among old vehicles, as previously assumed. Old vehicles, on average, have higher idle emissions than new vehicles, but they contribute relatively little to the total idle emissions because there are so few on the road. We compare roadside survey results at I/M and non-I/M locations in California, and observe identical tampering and overall failure rates at the two types of locations. We also show that motorists are taking steps to [open quotes]pass the test,[close quotes] and that the high-emitting vehicles' idle-emissions performance and tampering rates in the roadside surveys are unaffected by the Smog Check test. These results imply that success in California's Smog Check program in reducing emissions will require consideration of human behavior and the attendant negative incentives inherent in the program as historically conceived. 29 refs., 9 figs., 6 tabs.

Clinical and molecular cytogenetic observations in three cases of {open_quotes}trisomy 12p syndrome{close_quotes}  

SciTech Connect

Two unpublished cases with partial tandem duplication of 12p and one previously published case were studied by fluorescence in situ hybridization using 11 cosmid DNA probes from 12p. We propose that the smallest duplications of 12(p13.2pter) and 12(p13.1p13.33) produce the {open_quotes}trisomy 12p syndrome{close_quotes} which is characterized by heavy birth weight, macrocephaly, muscular hypotonia, short neck, flat face, high forehead, prominent cheeks, large philtrum, short nose with anteverted nostrils, and broad everted lower lip. From a review of the published cases we conclude that gross malformations are lacking in {open_quotes}pure{close_quotes} trisomy 12p, and mental retardation is severe in complete and moderate in partial trisomy 12p. Polydactyly and accessory nipples were found only with almost complete trisomy 12p. Abnormalities of hair growth may be related to a gene at 12p. The sub-band 12p11.21 may be critical for acrocallosal syndrome. Macrocephaly may be due to a metabolic disorder. 26 refs., 5 figs., 3 tabs.

Recognition and regional correlation of impact-related {open_quotes}Ames Crater{close_quotes} Arbuckle and Simpson reservoir lithofacies  

SciTech Connect

The concentric structural feature known as the {open_quotes}Ames Hole{close_quotes} or {open_quotes}Ames Crater{close_quotes}, located on the northern shelf of the Anadarko Basin, contains several heterogeneous and uniquely associated hydrocarbon reservoirs, as well as a locally thick (craterfilling) Middle Ordovician (Simpson shale) source rock. Critical diagnostic structural and morphological features, along with petrographic and shock metamorphism evidence, strongly support and impact origin of the structure. Principle crater reservoirs include extremely brecciated, fractured, and faulted, Cambro-Ordovician Arbuckle Group dolomites, Pre-Cambrian granodiorities, devitrified pseudo-pyroclastic (impact melt) rocks, and a rather homogenous, dolomitic ejecta-fallout breccia, which is present along the rim and flanks of the crater. Stratigraphic trapping of hydrocarbons associated with the presence of reservoir-quality ejecta-fallout lithologies unconformably present in the upper portion of the Arbuckle Group, and in reworked, arkosic/dolomitic impact-related lithofacies within the overlying basal Simpson Group, may exist both locally and regionally relative to the {open_quotes}Ames Crater{close_quotes}. Calibration of log-rock characteristics of ejecta-fallout reservoir lithofacies from key crater rim wells provides the basis for field-wide and regional inferences about lithologies, reservoir quality, and related production characteristics. An awareness and understanding of impact-related {open_quotes}Ames Crater{close_quotes} Arbuckle and Simpson lithofacies should lead to refinement of regional Lower and Middle Ordovician stratigraphy, and create renewed exploration strategies for potential stratigraphic traps.

Preparative purification of Trichoderma reesei native and {open_quotes}core{close_quotes} cellobiohydrolase I by electrophoresis and chromatofocusing  

SciTech Connect

The enzymes present in the cellulose complex produced by the fungus Trichoderma reesei have been the subject of considerable attention in consequence of their potential for converting cellulosic materials into glucose for further use in fermentation processes. Cellobiohydrolase I (CBH I) is the major component of crude commercial fungal cellulose preparations and catalyzes the conversion of insoluble cellulose into cellobiose. The primary structure of CBH I is known, and its tertiary structure, deduced from small-angle X-ray scattering studies, takes the shape of a tadpole with a catalytic head region known as {open_quotes}core{close_quotes} CBH I and a C-terminal cellulose-binding tail region. Removal of the tail can be accomplished with the protease papain, resulting in reduced activity towards insoluble substrates but unchanged activity towards soluble substrates.

Federal activities -- The Federal Energy Regulatory Commission`s {open_quotes}Mega-NOPR{close_quotes} and other related events  

SciTech Connect

This paper focuses on a major effort by the Federal Energy Regulatory Commission (FERC) to provide greater access to the nation`s electric power transmission grid. FERC has proposed a rule, commonly called the {open_quotes}Mega-NOPR{close_quotes}, which would require most utilities owning or controlling transmission lines to: (1) file non- discriminatory, open access wholesale transmission tariffs and (2) take transmission service for their own wholesale sales and purchases of electric energy at the filed rate. The proposed rule would also allow recovery of stranded costs associated with transmission access. While the rule would allow greater access to the transmission system by all entities and facilitate competition, there are significant concerns regarding environmental impacts and payment for costs generated by the changes in the system. This paper also reviews California`s recent electric industry restructuring decision and upcoming FERC activities to implement the decision.

Electrical conductivity measurements were made on emulsions formed, respectively, from the conjugate top-middle, top-bottom, and middle-bottom phase pairs that define the three sides of various nonionic amphiphile/oil/water {open_quotes}microemulsion{close_quotes} tie triangles. Effective-medium conductivity models and observations of creaming behavior were used to substantiate assignments of steady-state emulsion morphologies. The phase volume fractions at which morphology changes occurred were measured for both directions along each tie line, and the hysteresis was obtained as the difference between the volume fractions for the two directions. The results support the dispersion morphology diagram previously postulated, including the formation of mixtures of emulsions whose morphologies are the inverse of each other. 31 refs., 8 figs., 3 tabs.

Ulysses observations of a {open_quotes}density hole{close_quotes} in the high-speed solar wind  

SciTech Connect

Ulysses observations at mid and high heliographic latitudes have revealed a solar wind devoid of the large variations in density, temperature, and speed that are commonly observed at low latitudes. One event, however, observed on May 1, 1996, while Ulysses was located at {approximately}3.7AU and 38.5{degree}, stands out in the plasma data set. The structure, which is unique in the Ulysses high-latitude data set, is seen as a drop in proton density of almost an order of magnitude and a comparable rise in proton temperature. The event lasts {approximately}3(1)/(2) hours giving the structure a size of {approximately}9.6{times}10{sup 6}km (0.06 AU) along the spacecraft trajectory. Minimum variance analysis of this interval indicates that the angle between the average magnetic field direction and the minimum variance direction is {approximately}92{degree}, suggesting that the {open_quotes}density hole{close_quotes} may be approximated by a series of planar slabs separated by several tangential discontinuities. We discuss several possible explanations for the origin of this structure, but ultimately the origin of the density hole remains unknown. {copyright} 1998 American Geophysical Union

Nonequilibrium evolution of a {open_quotes}tsunami,{close_quotes} a high multiplicity initial quantum state: Dynamical symmetry breaking  

SciTech Connect

We propose to study the nonequilibrium features of heavy-ion collisions by following the evolution of an initial state with a large number of quanta with a distribution around a momentum {vert_bar}{rvec k}{sub 0}{vert_bar} corresponding to a {ital thin spherical shell} in momentum space, a {open_quotes}tsunami.{close_quotes} An O(N)({rvec {Phi}}{sup 2}){sup 2} model field theory in the large N limit is used as a framework to study the nonperturbative aspects of the nonequilibrium dynamics including a resummation of the effects of the medium (the initial particle distribution). In a theory where the symmetry is spontaneously broken in the absence of the medium, when the initial number of particles per correlation volume is chosen to be larger than a critical value the medium effects can restore the symmetry of the initial state. We show that if one begins with such a symmetry-restored, nonthermal, initial state, nonperturbative effects automatically induce spinodal instabilities leading to a {ital dynamical} breaking of the symmetry. As a result there is explosive particle production and a redistribution of the particles towards low momentum due to the nonlinearity of the dynamics. The asymptotic behavior displays the onset of Bose condensation of pions and the equation of state at long times is that of an ultrarelativistic gas although the momentum distribution is {ital nonthermal}. {copyright} {ital 1998} {ital The American Physical Society}

The communications convergence, brought about largely by the digitalization revolution, is now moving in a double helix through the horizontal telecommunications hierarchy.

MCI Metro, MCI/Nextel, and AT T/McCaw are poised to reach down into the traditionally [open quotes]local[close quotes] markets through wires and airwaves alike. Even the electric utilities are building persuasive business cases and regulatory arguments to transform their erstwhile internal communications systems, conduits, and rights-of-way into commercial networks offering cable TV, multimedia, Personal Communications Service (PCS), and alternative telephony services. The four principles in developing a regulatory standard should be: create standards that ease regulatory babysitting, recognize the relationship between the costs of regulatory compliance and building the networks, minimize transaction costs, and let the networks begin to grow now, without time and energy being spent on gaming the regulatory system.

Belgian experience in applying the {open_quotes}leak-before-break{close_quotes} concept to the primary loop piping  

SciTech Connect

The Leak Before Break (LBB) concept allows to eliminate from the design basis the double-ended guillotine break of the primary loop piping, provided it can be demonstrated by a fracture mechanics analysis that a through-wall flaw, of a size giving rise to a leakage still well detectable by the plant leak detection systems, remains stable even under accident conditions (including the Safe Shutdown Earthquake (SSE)). This concept was successfully applied to the primary loop piping of several Belgian Pressurized Water Reactor (PWR) units, operated by the Utility Electrabel. One of the main benefits is to permit justification of supports in the primary loop and justification of the integrity of the reactor pressure vessel and internals in case of a Loss Of Coolant Accident (LOCA) in stretch-out conditions. For two of the Belgian PWR units, the LBB approach also made it possible to reduce the number of large hydraulic snubbers installed on the primary coolant pumps. Last but not least, the LBB concept also facilitates the steam generator replacement operations, by eliminating the need for some pipe whip restraints located close to the steam generator. In addition to the U.S. regulatory requirements, the Belgian safety authorities impose additional requirements which are described in details in a separate paper. An novel aspect of the studies performed in Belgium is the way in which residual loads in the primary loop are taken into account. Such loads may result from displacements imposed to close the primary loop in a steam generator replacement operation, especially when it is performed using the {open_quote}two cuts{close_quotes} technique. The influence of such residual loads on the LBB margins is discussed in details and typical results are presented.

Characterization of a [open quotes]kissing[close quotes] hairpin complex derived from the human immunodeficiency virus genome  

SciTech Connect

Base-pair formation between hairpin loops-a [open quotes]kissing[close quotes] complex-is an RNA-folding motif that links two elements of RNA secondary structure. It is also a unique protein recognition site involved in regulation of ColE1 plasmid DNA replication. The trans-activation response element (TAR), a hairpin and bulge at the 5[prime] end of the untranslated leader region of the human immunodeficiency virus 1 mRNA, enhances the transcription of the virus and is necessary for viral replication. Gel electrophoresis and absorbance melting curves indicate that a synthesized RNA hairpin (Tar*-16) with a loop sequence complementary to the TAR loop sequence (CUGGGA) associates specifically with a 16-nucleotide TAR hairpin (Tar-16) to form a stable complex. RNase T1 probing indicates that the three guanines in the Tar-16 loop become inaccessible in the complex. NMR imino proton spectra reveal that 5 base pairs are formed between the two hairpin loops (Tar-16 and Tar*-16); only the adenine at the 3[prime] terminus of the TAR loop does not form a base pair with the 5[prime]-terminal uracil of the complementary loop. A 14-nucleotide hairpin [CCUA-(UCCCAG)UAGG] with a loop sequence complementary to the TAR loop is conserved within the gag gene of human immunodeficiency virus 1. A synthesized RNA hairpin corresponding to this conserved sequence also binds to the Tar-16 hairpin with high affinity. It is possible that the same RNA loop-loop interaction occurs during the viral life cycle. 40 refs., 7 figs.

Global climate change - the United Nations FCCC, {open_quotes}Berlin Mandate{close_quotes}, COP-2, and electric utilities  

SciTech Connect

Over the past 100 years, there has been a steady increase in man-made emissions of greenhouse gases (GHGs, such as carbon dioxide, methane, nitrous oxide, and most halogenated substances) due to human activities including combustion of fossil fuels and deforestation. Scientific studies suggest that these emissions are contributing to increases in atmospheric concentrations of GHGs which in turn, cause an enhanced greenhouse effect by trapping more of the sun`s energy leading to global climate change. Recently, a consensus position has emerged among the scientific community that man-made GHG emissions appear to be contributing to global climate change. Based on that finding, United States representative, Under Secretary of State Tim Wirth stated at the July 1996 meeting of the {open_quotes}Conference of Parties{close_quotes} (COP) of the FCCC, that global voluntary efforts to meet the GHG emission reduction goal have failed He called for the COP to expedite ongoing international negotiations toward establishing (in 1997) medium-term, realistic, legally-binding GHG emission targets and implementation schedules for each country. Setting a legally binding GHG emission target would have significant impacts on the nation, and especially on the electric utility sector. This article provides a general overview of the United States and international efforts toward implementing the FCCC and their potential impacts on the utility industry. A future article is anticipated to address an update on the international negotiations and their potential impacts on other sectors of the U.S. economy, and the rapidly growing GHG emissions from developing countries such as China and India.

Orex based {open_quotes}point of generation{close_quotes} low-level radioactive waste reduction program  

SciTech Connect

Nuclear power facilities, both commercial and government operated, generate material called Dry Active Waste (DAW). DAW is a by-product of maintenance and operation of the power systems which contain radioactive materials. DAW can be any material contaminated with radioactive particles as long as it is not a fluid, typically: paper, cardboard, wood, plastics, cloth, and any other solid which is contaminated and determined to be dry. DAW is generated when any material is exposed to loose radioactive particles and subsequently becomes contaminated. In the United States, once a material is contaminated it must be treated as radioactive waste and disposed of in accordance with the requirements of Title 10 of the Code of Federal Regulations. Problems facing all commercial and non-commercial nuclear facilities are escalating costs of processing DAW and volumetric reduction of the DAW generated. Currently, approximately 85% of all DAW generated at a typical facility is comprised of anti-contamination clothing and protective barrier materials. A typical 800 megawatt power station will generate between 6,000 to 10,000 cubic feet of DAW annually. Facilities that generate low-level radioactive waste need to dramatically reduce their waste volumes. This curtailment is required for several reasons: (1). The number of radioactive waste repositories now accepting new waste is limited. (2). The current cost of burial at an operating dump site is significant. Costs can be as high as $4,000 for a single 55 gallon drum. (3). The cost of burial is constantly increasing. (4). Onsite storage of low-level radioactive waste is costly and results in a burial fee at plant decommissioning. In order to address this issue, the industry must look to the application of {open_quotes}point of generation{close_quotes} technologies.

Mitochondrial DNA control region sequence variation suggests an independent origin of an {open_quotes}Asian-specific{close_quotes} 9-bp deletion in Africans  

SciTech Connect

The intergenic noncoding region between the cytochrome oxidase II and lysyl tRNA genes of human mitochondrial DNA (mtDNA) is associated with two tandemly arranged copies of a 9-bp sequence. A deletion of one of these repeats has been found at varying frequencies in populations of Asian descent, and is commonly referred to as an {open_quotes}Asian-specific{close_quotes} marker. We report here that the 9-bp deletion is also found at a frequency of 10.2% (66/649) in some indigenous African populations, with frequencies of 28.6% (20/70) in Pygmies, 26.6% (12/45) in Malawians and 15.4% (31/199) in southeastern Bantu-speaking populations. The deletion was not found in 123 Khoisan individuals nor in 209 western Bantu-speaking individuals, with the exception of 3 individuals from one group that was admixed with Pygmies. Sequence analysis of the two hypervariable segments of the mtDNA control region reveals that the types associated with the African 9-bp deletion are different from those found in Asian-derived populations with the deletion. Phylogenetic analysis separates the {open_quotes}African{close_quotes} and {open_quotes}Asian{close_quotes} 9-bp deletion types into two different clusters which are statistically supported. Mismatch distributions based on the number of differences between pairs of mtDNA types are consistent with this separation. These findings strongly support the view that the 9-bp deletion originated independently in Africa and in Asia.

Did the Mississippian Lodgepole buildup at Dickinson Field (North Dakota) form as a gas seep ({open_quotes}vent{close_quotes}) community?  

SciTech Connect

The Lower Mississippian Lodgepole carbonate buildup reservoir at Dickinson Field in Stark County, North Dakota, has been widely reported as being a Waulsortian (or Waulsortian-like) mound. The term {open_quotes}Waulsortian mound{close_quotes} is used for a variety of Early Mississippian carbonate buildups that share a number of features including an abundance of carbonate mud, a {open_quotes}framework{close_quotes} of organisms such as fenestrate bryozoans and crinoids that tended to trap or baffle sediment, and a general absence of marine-cemented reef framework. Although the age of the Lodgepole mound at Dickinson Field qualifies it to be a Waulsortian mound, petrographic study of cores reveals that the reservoir rocks are quite unlike those in true Waulsortian mounds. Instead of being dominated by carbonate mud, the Lodgepole mound core is dominated by marine cement. Furthermore, ostracods and microbial limestones are common in the mound core where they occur with crinoid debris and small amounts of bryozoan, coral, and brachiopod debris. The abundant microbial limestones and marine cement indicate that the Dickinson mound formed as a lithified reef on the sea floor rather than as a Waulsortian mud mound. The microbial limestones, marine cement, and common ostracods in the mount core, and the fact that the mound nucleated almost directly o top of the Bakken Shale, suggest that the Dickinson Lodgepole mound formed at the site of a submarine spring and gas seep.

Multiple recurrence of trisomy 21 in two Bedouin families: Parental gonadal mosaicism or {open_quotes}aneuploidy{close_quotes} gene effect?  

SciTech Connect

Two unrelated multiplex Down syndrome families is reported in Kuwait among the highly inbred population with Bedouin ancestors. Each family showed recurrent aneuploidies in three sibs with regular trisomy 21. Recurrent regular trisomy 21 in two or more siblings of healthy, normal parents (parental age <35 years) occurs rarely. Several possible etiological factors for recurrent aneuploidy have been suggested. The recurrence risks for regular trisomy 21 based on livebirth and prenatal diagnosis data were estimated at 1% - 2% for young women. However, there are no estimates for multiple recurrence of regular trisomy 21 in the young parents (<35 years). Clustering of trisomy 21 and trisomy 18 have been observed in Bedouin tribal population. The possibility of parental gonadal mosaicism and/or a possibility of an {open_quotes}aneuploidy gene{close_quotes} effect should be considered in practical genetic counselling of families with multiple recurrence of trisomy 21.

Recently, Lopez-Pajares et al. (1993) reported identification of a translocation between the short arm of a chromosome 5 and the long arm of a chromosome 21 in a patient who was thought to be monosomy 21. This study is the first application of a chromosome 21 painting probe, pBS-21, and fluorescent in situ chromosome hybridization (FISH) to revise an earlier diagnosis of monosomy 21. We have now restudied skin fibroblast cultures, GM00137B, that are still available from another patient previously described as {open_quotes}presumptive monosomy 21{close_quotes} and have found that this case also has a translocation involving chromosomes 21 and 4. The authors urge that all previous cases of what appeared to be monosomy 21 should be re-examined with FISH to confirm or revise the original diagnosis so that genetic counseling of the family may be updated. 3 refs., 3 figs.

Compatibility issues of potential payloads for the USA/9904/B(U)F-85 RTG transportation system (RTGTS) for the {open_quotes}Pluto Express{close_quotes} mission  

SciTech Connect

The specific electric power system for the {open_quotes}Pluto Express{close_quotes} mission has yet to be specified. However, electric power will be provided by either radioisotopic thermoelectric generators (RTG), radioisotope thermophotovoltaic systems (RTPV), alkali metal thermal to electrical conversion (AMTEC) systems, radioisotope Stirling systems, or a combination of these. The selected radioisotopic power system will also be transported using the USA/9904/B(U)F-85, Radioisotope Thermoelectric Generator (RTG) Transportation System (RTGTS). As a result, all of the potential payloads present uniquely different environmental and physical configuration requirements.

Depositional environment and distribution of Late Cretaceous [open quotes]source rocks[close quotes] from Costa Rica to West Africa  

SciTech Connect

Late Cretaceous [open quotes]source rocks[close quotes] from Costa Rica, western and eastern Venezuela, and Trinidad were studied using organic and inorganic geochemistry, biostratigraphy, and sedimentology in order to determine their depositional environments. Bulk mineralogy and major element geochemistry for 304 samples were combined with Rock Eval data and extract biomaker analysis to infer the types and distributions of the various Late Cretaceous productivity systems represented in the dataset. When data from this study are combined with published and proprietary data from offshore West Africa, Guyana/Suriname, and the central Caribbean, they show that these Late Cretaceous units can be correlated by their biogeochemical characteristics to establish their temporal and spatial relationships. Paleogeographic maps constructed for the early to late Cenomanian, Turonian, Coniacian to middle Santonian, and late Santonian to latest Campanian show that upwelling and excessive fluvial runoff were probably the dominant sources of nutrient supply to the coastal productivity systems. The late Santonian to Maastrichtian rocks examined in this study indicate that organic material was poorly preserved after deposition, even though biologic productivity remained constant or changed only slightly. A rapid influx of oxygenated bottom water may have occurred following the opening of a deep water connection between the North and South Atlantic oceans, and/or separation of India from Africa and the establishment of an Antarctic oceanic connection. This study suggests that the most important factors that controlled source rock quality in northern South America were productivity, preservation, degree of clastic dilution, and subsurface diagenesis.

A {open_quotes}balanced{close_quotes} Y:16 translocation with the Y breakpoint just proximal to the Yq heterochromatin boundary associated with Turner-like neonatal lymphedema suggests the location of a potential anti-Turner gene  

SciTech Connect

A male patient with Turner-like hydrops in the newborn period (Bonnevie-Ullrich syndrome) was studied. The extensive nucchal cystic hygroma and hydrops resolved over several weeks. The karyotype was 46,X,t(Y;16)(q11.2;q24). The paternal karyotype was normal. Chromosome painting with the heterochromatic long arm repeat DYZ2 disclosed that all the hybridization was on the derivative 16. This was confirmed by chromosome painting with DYZ1, the other major Y long arm heterochromatic repeat, and DYZ3, the Y alphoid, centromeric repeat, which showed chromosomal separation of the 2 stained regions. A {open_quotes}FISHing trip{close_quotes} was performed using the Y YAC contig created in Dr. David Page`s laboratory. This disclosed 2 YACs located just proximal to the Y heterochromatin which {open_quotes}jumped{close_quotes} the translocation. The recent discovery of a candidate gene for the azoospermia factor (AZF) in this region suggests the possibility that there are several Y-expressed genes adjacent to the heterochromatin boundary as there are near the pseudoautosomal boundary.

Non-negative Feynman{endash}Kac kernels in Schr{umlt o}dinger{close_quote}s interpolation problem  

SciTech Connect

The local formulations of the Markovian interpolating dynamics, which is constrained by the prescribed input-output statistics data, usually utilize strictly positive Feynman{endash}Kac kernels. This implies that the related Markov diffusion processes admit vanishing probability densities only at the boundaries of the spatial volume confining the process. We discuss an extension of the framework to encompass singular potentials and associated non-negative Feynman{endash}Kac-type kernels. It allows us to deal with a class of continuous interpolations admitted by general non-negative solutions of the Schr{umlt o}dinger boundary data problem. The resulting nonstationary stochastic processes are capable of both developing and destroying nodes (zeros) of probability densities in the course of their evolution, also away from the spatial boundaries. This observation conforms with the general mathematical theory (due to M. Nagasawa and R. Aebi) that is based on the notion of multiplicative functionals, extending in turn the well known Doob{close_quote}s h-transformation technique. In view of emphasizing the role of the theory of non-negative solutions of parabolic partial differential equations and the link with {open_quotes}Wiener exclusion{close_quotes} techniques used to evaluate certain Wiener functionals, we give an alternative insight into the issue, that opens a transparent route towards applications.{copyright} {ital 1997 American Institute of Physics.}

Use of geostatistic techniques to describe a reservoir to be submitted into a secondary recovery process field case: {open_quotes}Eocene B-Inferior/VLG-3659, Ceuta, Venezuela{close_quotes}  

SciTech Connect

This study presents the results of an integrated reservoir study of the Eocene B-Inferior/VLG-3659, Area 7, Ceuta filed. This field located in the Maracaibo Lake in the western side of Venezuela. The objective was to evaluating the feasibility to implement a secondary recovery project by means of water flooding. Core information was used for this study (194 ft), PVT analysis, RFI, build-up and statistic`s pressure analysis, modem logs and production history data. Using geostatistical techniques (Kriging) it was defined a low uncertainty geological model that was validated by means of a black oil simulator (Eclipse). The results showed a good comparison of historical pressure of the reservoir against those obtained from the model, without the need of {open_quotes}history matching{close_quotes}. It means without modifying neither the initial rock properties nor reservoir fluids. The results of this study recommended drilling in two new locations, also the reactivation of four producing wells and water flooding under peripherical array by means of four injection wells, with the recovery of an additional 30.2 MMSTB. The economical evaluation shows an internal return rate of 31.4%.

Mutation in and lack of expression of tyrosinase-related protein-1 (TRP-1) in melanocytes from an individual with brown oculocutaneous albinism: A new subtype of albinism classified as {open_quotes}OCA3{close_quotes}  

SciTech Connect

Most types of human oculocutaneous albinism (OCA) result from mutations in the gene for tyrosinase (OCA1) or the P protein (OCA2), although other types of OCA have been described but have not been mapped to specific loci. Melanocytes were cultured from an African-American with OCA, who exhibited the phenotype of Brown OCA, and his normal fraternal twin. Melanocytes cultured from the patient with OCA and the normal twin appeared brown versus black, respectively. Melanocytes from both the patient with OCA and the normal twin demonstrated equal amounts of NP-40-soluble melanin; however, melanocytes from the patient with OCA contained only 7% of the amount of insoluble melanin found from the normal twin. Tyrosinase-related protein-1 (TRP-1) was not detected in the OCA melanocytes by use of various anti-TRP-1 probes. Furthermore, transcripts for TRP-1 were absent in cultured OCA melanocytes. The affected twin was homozygous for a single-bp deletion in exon 6, removing an A in codon 368 and leading to a premature stop at codon 384. Tyrosine hydroxylase activity of the OCA melanocytes was comparable to controls when assayed in cell lysates but was only 30% of controls when assayed in intact cells. We conclude that this mutation of the human TRP-1 gene affects its interaction with tyrosinase, resulting in dysregulation of tyrosinase activity, promotes the synthesis of brown versus black melanin, and is responsible for a third genetic type of OCA in humans, which we classify as {open_quotes}OCA3.{close_quotes} 69 refs., 7 figs., 3 tabs.

Electronic stopping in a He-H{sub 2} mixture substantially exceeds Bragg{close_quote}s rule value

Experimentally we find {var_epsilon} to exceed the Bragg value by more than 50{percent}.

Absence of a {open_quote}{open_quote}Threshold Effect{close_quote}{close_quote} in the Energy Loss of Slow Protons Traversing Large-Band-Gap Insulators  

SciTech Connect

The electronic stopping cross section {var_epsilon} of slow hydrogen projectiles in large-band-gap insulators has been measured at energies of a few keV. Even at velocities as low as v{sub 0}/3 (v{sub 0}=c/137) , we find no influence of the band gap on the velocity dependence of {var_epsilon} , contrary to the case of gaseous targets with similar minimum excitation energy. The magnitude of {var_epsilon} and its essentially linear velocity dependence allow us to arrive at the following conclusion: Electron promotion processes contribute substantially to stopping due to formation of molecular orbitals. This points towards the existence of a bound electron state at a proton that moves slowly in an insulator. A simple model based on the calculation of molecular orbital correlation diagrams for the H/LiF collision system supports the idea of local reduction of the band gap of an insulating target. {copyright} {ital 1997} {ital The American Physical Society}

SciTech Connect

Shortcomings of a momentum-space treatment of strong absorption, as discussed in the preceding Comment, are only of concern at low projectile energies, {gamma}{lt}1.5. At intermediate and high energies, for which the quantum-mechanical equivalent-photon spectrum is intended, the quantum-mechanical cross sections are reduced relative to the semiclassical results whether one treats strong effects via a momentum-space or an impact-parameter (spatial) cutoff. At these energies the origin of the discrepancy between the predictions of fully quantum-mechanical and the semiclassical calculations cannot be traced to differences in the treatment of strong-interaction effects. Rather, they arise from quantum effects neglected in the semiclassical calculations. {copyright} {ital 1997} {ital The American Physical Society}

The Solid Waste Authority: {open_quotes}This place is for the birds{close_quotes}  

SciTech Connect

The Solid Waste Authority of Palm Beach County (SWA) manages a waste-to-energy facility and landfill adjacent to a site which, during the 1985 Florida drought, served as the largest communal Snail Kite (Rostrhamus sociabilis plumbeus) roost documented in the United States. Listed as an endangered species, the Snail Kite initiated a Section 7 consulation process as a USCOAE Dredge & Fill permit was sought for construction in 1987. In response to environmental permit requirements, SWA developed and implemented a Wildlife Conservation & Management Program which evaluated the roost`s response to activities associated with site development. Specifically, a seven-year bird monitoring program was conducted on kite usage of this roost from 1987-1993. Impact assessment was expanded to include monitoring the mixed-species wading bird colony which inhabits the same roosting area. Monitoring at the community level serves as a better environmental indicator because Snail Kites are nomadic and respond to regional water level changes. This paper gives an overview of the environmental concerns and approach taken to monitor the roost, describes the different components of the bird monitoring program, and summarizes the findings of the 7-year data collection. An evaluation of the SWA project with regards to impacts on Snail Kite and wading bird usage of the area is also discussed.

Citrate-based {open_quotes}Talspeak{close_quotes} actinide-lanthanide separation process  

SciTech Connect

Lanthanide elements are produced in relatively high yield by fission of {sup 235}U. Almost all the lanthanide isotopes decay to stable nonradioactive lanthanide isotopes in a relatively short time. Consequently, it is highly advantageous to separate the relatively small actinide fraction from the relatively large quantities of lanthanide isotopes. The TALSPEAK process (Trivalent Actinide Lanthanide Separations by Phosphorus-reagent Extraction from Aqueous Complexes) is one of the few means available to separate the trivalent actinides from the lanthanides. Previous work based on the use of lactic or glycolic acid has shown deleterious effects of some impurity ions such as zirconium(IV), even at concentrations on the order of 10{sup {minus}4} M. Other perceived problems were the need to maintain the pH and reagent concentrations within a narrow range and a significant solubility of the organic phase at high carboxylic acid concentrations. The authors` cold experiments showed that replacing the traditional extractants glycolic or lactic acid with citric acid eliminates or greatly reduces the deleterious effects produced by impurities such as zirconium. An extensive series of batch tests was done using a wide range of reagent concentrations at different pH values, temperatures, and contact times. The results demonstrated that the citrate-based TALSPEAK can tolerate appreciable changes in pH and reagent concentrations while maintaining an adequate lanthanide extraction. Experiments using a three-stage glass mixer-settler showed a good lanthanide extraction, appropriate phase disengagement, no appreciable deleterious effects due to the presence of impurities such as zirconium, excellent pH buffering, and no significant loss of organic phase.

{open_quotes}Industry views--timing/structure of consultative process{close_quotes}  

SciTech Connect

This paper examines industry`s perspective on the issues concerning the politics and economics of climatic change. The climate change issue complexity goes beyond science and involves: technology, economics, lifestyle, population, intergenerational equity, etc. Industry resources should be actively involved in technology, timeframes, economic assessments, and the political process. Climate mitigation options should be viewed on a holistic or total impact basis. Technology and economic assessment should not create winners and losers. The climate change process is like peeling an onion - long timeframes are required for cultural and infrastructure changes, there are both short term small improvement and long term structural changes, and implementation may take generations. Interdisciplinary communications are critical, cutting across the fields of social science, physical science, economics, technology, demographics, etc. Finally, industry must play or be played - industry can either help shape or be left to live with policy.

{open_quotes}Perspectives on greenhouse gas emissions trends{close_quotes}  

SciTech Connect

This paper discusses the common perspective on greenhouse gas emissions that well over half of carbon dioxide emissions originate in developing countries. According to IPCC data, in 1991 energy-related carbon emissions from non-OECD countries accounted for 57% of the global total, while emissions from OECD countries accounted for 43%. This perspective is misleading and oversimplified. The true picture of greenhouse gas emissions is much more complex, and varies by country and gas. On a country by country basis, the OECD countries are the largest current and historic emitters. The developed countries must take the lead in reducing greenhouse gas emissions. We cannot simply look at greenhouse gases in the context of OECD and non-OECD countries. There is a huge disparity between the emissions of Russia, Eastern European and certain Asian Countries compared to other non-OECD countries. On a per country basis, most developing country contributions to the global greenhouse gas budget are negligible. Finally, all greenhouse gases must be considered. While energy-related CO2 will remain the most important greenhouse gas over the next 25 years, land-use related CO2 or anthropogenic methane cannot be ignored or underestimated. Since the relative importance of various emission sources varies from region to region, greenhouse gas mitigation strategies must be tailored to the particular circumstances and factors friving emission in each region.

{open_quotes}Industry overview: Agriculture and forestry{close_quotes}  

SciTech Connect

The Climate Change negotiators left Berlin, very tired and bleary eyed, but with a Declaration which included agreements, among other things, to take a close look at what the likely effects of commitments will be and where those commitments will be going between now and 2000. Debate would then open on a new or amended legal instrument to meet the Objective of the Climate Change Convention, in the Twenty First Century. One hundred and fifty nations also declared that a new way of transfering technology could be tried on a pilot basis, thus, Joint Implementation also will move into the Twenty First Century. These two parts of the Berlin Declaration are very important to the role to be played by agriculture and forestry. Agriculture and forestry currently are playing a significant role and will continue this role in the stabilization of atmospheric concentrations of greenhouse gases. These two sectors, whether in an industrialized nation or in developing nation represent the only economically viable technologies for carbon sequestration, at this time. These sinks are constrained, however, by the reservoir capacity of the soils and are a function of temperature, moisture, soil, and history of use. The outlook is, therefore both one of optimisim and of pessimism. The view will have some global overtones, however, the focus is primarily within the U.S.

A novel form of {open_quotes}Tyrosinase-positive{close_quotes} oculocutaneous albinism  

SciTech Connect

Tyrosinase-positive oculocutaneous albinism (ty-pos OCA) is an autosomal recessive disorder in which the biosynthesis of melanin pigment is greatly reduced in the skin, hair, and eyes. We have shown that typical ty-pos OCA (OCA2) results from mutations of the P gene in chromosome segment 15q11-q13. We have also shown that some patients diagnosed with ty-pos OCA actually have mild forms of type I OCA (OCAI), resulting from mutations at the tyrosinase (TYR) gene at 11q14-q21. However, in about one-third of patients with ty-pos OCA we have failed to identify abnormalities of either the P or TYR genes, suggesting the possible existence of a third ty-pos OCA locus. To test this hypothesis, we investigated a large, complex, inbred Pakistani kindred. Affected individuals exhibit slight skin pigmentation with no tanning, hair that is silver at birth and darkens somewhat over time, brown irides, and reduced visual acuity with nystagmus. SSCP/heteroduplex screening and complete DNA sequence analysis of TYR gene in the proband identified no abnormalities, and analysis of a CA repeat in the TYR gene promoter showed no linkage of ty-pos OCA to this marker in this kindred. SSCP/ heteroduplex screening of the P gene also detected no abnormalities, and the (inbred) proband was heterozygous for numerous intragenic polymorphisms. These data thus exclude TYP and P. We next carried out genetic linkage analyses and homozygisty mapping using various SSLP repeats at the locations of the human homologues of the mouse brown (TYRP, 9p23), slaty (13q32), and silver (12pter-q21) genes, all of which are associated with generalized hypopigmentation in mutant animals. However, we found no evidence of linkage of any of these markers. We are currently carrying out similar analyses using markers near the putative locations of the human homologues of several other mouse hypopigmentation genes in an effort to map this novel human ty-pos OCA locus.

On the {open_quotes}oxygen in heavy-ion tracks{close_quotes} hypothesis  

SciTech Connect

Two well-known chemical systems, the Fricke (system I) and the Fricke + ethanol (system II), were irradiated with intermediate-energy {sup 12}C and {sup 40}Ca ion beams. A vertical beam allowed us to study radiation phenomena in the bulk of a stirred solution and in the motionless surface layer in contact with air. The G value of the formation of Fe{sup 3+} in system II compared to system I allowed us to distinguish between oxygenated and hypoxic conditions in the reaction zone, i.e., in our case, in the vicinity of the heavy-ion path. Our results for nonstirred solutions that are open to air indicate an oxygen deficiency in the reaction zones even for medium-intensity ion fluences. The origin of this effect is not completely clear at present. Nevertheless, it is evident that postulated mechanisms for the generation of O{sub 2} in heavy-ion tracks are not sufficient to keep an oxygenated condition in nonstirred solutions. We cannot exclude the possibility that the low oxygen enhancement ratio observed in experiments with high-LET radiation may arise, at least partly, from an insufficiency rather than an excess of oxygen. 32 refs., 1 fig., 3 tabs.

Dow Corning, Carrollton Plant, is a 150 acre silicone manufacturing facility, with approximately 250 emission points, located on the banks of the Ohio River. It is included in the SOCMI industry category, and is a source for HAP`s and criteria air pollutants. The facility utilized a variety of control devices and vent handling schemes to successfully achieve its goal of greater than 90% reduction in HAP`s emissions from base year emissions. Data will show how emissions were reduced from 667,500 lb. in 1988 (well below permitted levels) to less than 66,750 lb. in 1994 with minimal capital expenditure. These reductions were made concurrent with significant production increases at the facility. An innovative team approach comprised of key individuals was used. Operations, quality, supply, and environmental representatives challenged all employees to seek creative solutions to obtain the emissions reductions goal. Tools and resources used by the team included SPC, CIM (Computer Integrated Manufacturing), on-line DCS parametric monitoring devices, portable analyzers, and control equipment specialists and consultants. Operator technicians, manufacturing engineers, and plant management all equally and successfully took ownership of the effort which helps ensure ongoing compliance and improvement. 8 figs.

Explanations for {open_quotes}anomalous methane{close_quotes} in submarine hydrothermal fluids  

SciTech Connect

Concentrations of CH{sub 4}, CO{sub 2} and H{sub 2} reported for submarine hydrothermal fluids are not generally in equilibrium at the measured temperatures. Although the concentrations of CH{sub 4} in Endeavor Ridge fluids are called anomalous the degree of disequilibrium indicated by the fluid composition is essentially the same as that of all other fluids except one measurement from 21{degrees}N on the East Pacific Rise (EPR). Therefore, it is possible that a single explanation may serve to reconcile a majority of the data on hydrothermal fluids. The 21{degrees}N EPR fluid has the highest reported concentration of H{sub 2}, a factor of 4 to 12 greater than other fluids. One explanation is that all other H{sub 2} analyses are low owing to H{sub 2} loss during sampling or analysis. If this is not the case, then a second plausible hypothesis is that microbial methanogenesis in the downwelling parts of submarine hydrothermal systems contributes CH{sub 4} to all systems, even those lacking any plausible sedimentary source of organic matter. Thermodynamic analysis of all available data shows that any approach toward equilibrium at temperatures {<=}300{degrees}C could explain the concentrations of CH{sub 4}. This analysis also shows that methanogenesis is an energetically favored lifestyle as hydrothermal fluids mix with seawater at temperatures from {>=}50{degrees}C to {<=}350{degrees}C, assuming that the H{sub 2} analyses are reliable. In fact, these two explanations might be related. Any thermophilic methanogens trapped during collection of a mixed sample of seawater and vent fluid could feast on CO{sub 2} and H{sub 2} as the sample cooled, and the extent of disequilibrium may be governed by the temperature dependence of CH{sub 4}/CO{sub 2}/H{sub 2} reactions and the optimal temperature range of the organisms.

A nuclear reactor control system is provided in a nuclear reactor having a core operating in the fast neutron energy spectrum where criticality control is achieved by neutron leakage. The control system includes dual annular, rotatable reflector rings. There are two reflector rings: an inner reflector ring and an outer reflector ring. The reflectors are concentrically assembled, surround the reactor core, and each reflector ring includes a plurality of openings. The openings in each ring are capable of being aligned or non-aligned with each other. Independent driving means for each of the annular reflector rings is provided so that reactor criticality can be initiated and controlled by rotation of either reflector ring such that the extent of alignment of the openings in each ring controls the reflection of neutrons from the core. 4 figures.

United States based agricultural {open_quotes}waste products{close_quotes} as fillers in a polypropylene homopolymer  

SciTech Connect

With the advent of modern coupling agents (MAPP or maleic anhydride grafted polypropylene), the potential use of various types of renewable, sustainable agricultural byproducts as fillers in thermoplastics is explored. Over 7.7 billion pounds of fillers were used in the plastics industry in 1993. With sharp price increases in commodity thermoplastics (i.e. approximately 25% in 94`), the amount of fillers in thermoplastic materials will increase throughout the 90`s. Various types of agricultural fibers are evaluated for mechanical properties vs. 50% wood flour and 40% talc filled polypropylene (PP). The fibers included in this study are: kenaf core, oat straw, wheat straw, oat hulls, wood flour (pine), corncob, hard corncob, rice hulls, peanut hulls, corn fiber, soybean hull, residue, and jojoba seed meal. Composite interfaces were modified with MAPP to improve the mechanical properties through increased adhesion between the hydrophilic and polar fibers with the hydrophobic and non-polar matrix. The agro-waste composites had compositions of 50% agro-waste/48% PP/2% MAPP. All of the agricultural waste by-products were granulated through a Wiley mill with a 30 mesh screen and compounded in a high intensity shear-thermo kinetic mixer. The resultant blends were injection molded into ASTM standard samples and tested for tensile, flexural, and impact properties. This paper reports on the mechanical properties of the twelve resultant composites and compares them to wood flour and talc-filled polypropylene composites. The mechanical properties of kenaf core, oat straw, wheat straw, and oat hulls compare favorably to the wood flour and talc-filled PP, which are both commercially available and used in the automotive and furniture markets.

{open_quotes}Understanding district energy customer behavior - the key to getting customers and keeping them happy{close_quotes}  

SciTech Connect

The market share achieved by district energy systems is frequently represented as a percentage of a particular country`s total energy consumption, or as a percentage of the energy used for heating and cooling. While such characterizations of district energy`s market share are valid and important from a producer`s perspective, the position of the customer is not well represented. The effectiveness of communicating market share in this way greatly depends on the district energy customers` knowledge about the local, regional and national energy markets. It also fails to take into account the differences among customer buildings and their individual energy consumption patterns. An alternative view of market share is suggested when the perspective of the district energy markets shifts from that of the producer`s to the ends user`s. End users of district energy typically are responsible for the ownership and/or the operation of a building. This includes providing energy for comfort, lighting and any processes being conducted in the building. Fundamentally, district energy customers are in the property management business. Their business operations are represented and rated with respect to the building area they manage. Frequently, several buildings are managed by one company. An extensive amount of research has been done about the behavior of consumers when making buying decisions. This includes the fact that product and service buying behavior differs. Also, the field of customer satisfaction is rich with clues on how to keep our customers happy with their decisions to use district energy. This report presents key considerations about buyer behavior and customer satisfaction as they relate to marketing in the district energy field.

Keys to evaluating {open_quotes}paleokarst{close_quotes} reservoirs - guidelines from Quaternary carbonates and enhanced petrography  

SciTech Connect

Paleokarst is often invoked to explain reservoir development in ancient brecciated carbonates. However, the paleokarst model is valid only when fabrics seen in Quaternary cave systems are present and petrography of the non-brecciated zones supports subaerial exposure. Quaternary caves typically exhibit early fractures, microscopic to cavernous secondary porosity, solution collapse and brecciation, cave cements, and reddish-brown cave fill. Inter-cavern rocks show fabric-selective dissolution, porosity inversion, precompaction cements, and capping laminated soil crusts. In brecciated Ellenburger and Upper Elk Point (Devonian, W. Canada) reservoirs, major discrepancies exist between what the paleokarst model predicts and what is actually observed. Reddish calcretes, cavernous porosity and cave cements are absent. Enhanced petrography reveals relict sutured grains, implying burial dolomitization. These same dolomites are brecciated and breccia clasts contain stylolites rotated at different angles to each other and the horizon, implying burial brecciation. Fractures cutting these burial dolomites and stylolites are burial in origin. Preserved secondary porosity is unrelated to brecciated zones and facies controlled. Therefore, brecciation and reservoir quality in both sequences were created by burial dissolution of replacement dolomites and not by subaerial karstification. Brecciation alone does not prove the unconformity-related paleokarst model or the timing of porosity development.

Stoichiometric redox measurements and X-ray photoelectron spectroscopy (XPS or ESCA) studies were performed on an allyl-based Mo/SiO[sub 2] catalyst (1.7 wt % Mo) obtained by the sublimation of Mo([eta][sup 3]-C[sub 3]H[sub 5])[sub 4] onto SiO[sub 2] at 40 [degrees]C. The average oxidation state estimated from stoichiometric measurements correlated well with those reported in the literature. ESCA results indicated that reduction of the Mo/SiO[sub 2] catalyst at 550 [degrees]C primarily led to the formation of Mo[sup 2+]. Also, the results were consistent the reported reversibility of the redox cycle. However, the reported formation of discrete Mo[sup 4+] by oxidation of the reduced catalyst at room temperature could not be substantiated. 17 refs., 4 figs., 2 tabs.

Results of these tests and analysis indicated that the BS-25 (x=0.25 in BSX) and CS-50 (x=0.50 in CSX) ceramics had the most desirable properties for casting metal with ceramic in place. Finite element analysis (FEA) of metal casting (with ceramic in place) was conducted to analyze thermomechanical stresses generated and determine material property requirements. Actual metal casting trials were also conducted to verify the results of finite element analysis. In initial trials, the ceramic cracked because of the large thermal expansion mismatch (hoop) stresses (predicted by FEA also). A process for introduction of a compliant layer between the metal and ceramic to alleviate such destructive stresses was developed. The compliant layer was successful in preventing cracking of either the ceramic or the metal. In addition to these achievements, pressure slip casting and gel-casting processes for fabrication of NZP components; and acoustic emission and ultrasonics-based NDE techniques for detection of microcracks and internal flaws, respectively, were successfully developed.

Molecular genetics of the glaucomas: Mapping of the first five {open_quotes}GLC{close_quotes} loci  

SciTech Connect

Glaucoma encompasses a complex of ocular-disease entities characterized by an optic neuropathy in which degeneration of retinal ganglion cells leads to a characteristic excavation of the head of the optic nerve. Such damage causes progressive narrowing of the visual fields and, when uncontrolled, blindness. Affected people often have ocular hypertension defined as intraocular pressures consistently >21 mm Hg in both eyes. Although ocular hypertension is no longer an obligatory diagnostic criterion for glaucoma, it is still recognized as one of the most important risk factors. A diagnosis of glaucoma is made after observation of the characteristic atrophy of the optic nerve, which is associated with typical visual field defects. In 1992, the World Health Organization estimated that, in the global population, 5.2 million people were blind as a result of glaucoma, making it the third leading cause of blindness worldwide. The most common form is adult-onset primary open-angle glaucoma, which represents {ge}50% of all cases of glaucoma. Among Caucasians, this form of the disorder affects {approximately}2% of the population >45 years old. In African Americans, prevalence of adult-onset open-angle glaucoma is three to four times higher than that observed in White Americans. More than 15 million North Americans may have some form of glaucoma, but at least half of them may not be aware of it. 43 refs., 1 tab.

Intermodal transportation simulation system {open_quotes}A new prototype for the 21st century{close_quotes}  

SciTech Connect

The National Aviation and Transportation Center{reg_sign} (NAT Center) has established the first Intermodal Transportation Simulation System (OTSS) in the United States. This system identifies and contributes to the solution of intermodal transportation problems using computer-based simulation that includes all three spatial dimensions: aerial, surface and subsurface. The system utilizes the five human senses and all modes of transportation related to air, land and sea. The first phase of this program is supported by a $2.9 million United States Department of Transportation grant. This funding was used to recently establish an advanced technology simulation laboratory. The simulation laboratory is used for strategic planning and problem solving, environmental issues, route and system planning, public participation and conflict resolution, emergency preparedness and risk assessment, human factor issues, logistics and scheduling, economic development as well as financial feasibility and business planning. This technology helps define the systems that enable transportation specialists to better understand the movement of people and goods in a safe and efficient manner using risk-free and less environmentally intrusive training techniques. The simulation system is capable of evaluating problems and provide training at the micro and macro levels. Micro activities include operator-level training, planning and gaming; macro activities range from regional planning to project design and evaluation. Some of the other activities involve personnel and equipment resource management and electronic multimedia simulations applied to large-scale transportation projects and issues using electronic rehearsal exercises. Key to the use of this simulation based facility is the enhancement of transportation that has economic development benefits.

Detection of {open_quotes}cryptic{close_quotes}karyotypic rearrangements in closely related primate species by fluorescence in situ hybridization (FISH) using human subtelomeric DNA probes  

SciTech Connect

Specific human subtelomeric DNA probes were used to reveal cryptic chromosomal rearrangements that cannot be detected by conventional high resolution cytogenetic techniques, or by chromosomal in situ suppression hybridization using whole chromosome paint analysis. Two cosmids containing different subtelomeric DNA sequences were derived from human chromosome 19 and designated as 7501 and 16432. Cosmid 7501 was hybridized to chromosomes from humans, chimpanzee, gorilla and orangutan. In humans, 7501 consistently labeled chromosomes 3q, 15q, and 19p. Additional chromosomes were labeled in different individuals, indicating a polymorphic distribution of this sequence in the human genome. In contrast, 7501 consistently and strongly labeled only the q arm terminus of chromosome 3 in both chimp and gorilla. The identification of the chromosome was made by two-color FISH analysis using human chromosome 4-specific paint and homologous to human chromosome 4. None of the human subjects showed labeling of chromosome 4 with 7501. This finding suggests that in the course of human evolution, subsequent to the divergence of humans and African apes, a cryptic translocation occurred between the ancestral human chromosome 4 and one or more of the other human chromosomes that now contain this DNA segment. In orangutan, 7501 labeled a single acrocentric chromosome pair, a distinctly different chromosome than that labeled in chimp and gorilla. Comparison of chromosome sites labeled with cosmid 16432 showed the distribution of signals on chromosome 1q arm is the same for humans and chimp, but different in the gorilla. Humans and chimps show distinct labeling on sites 1q terminus and 1q41-42. In gorilla, there is instead a large cluster of intense signal near the terminus of 1q that clearly does not extend all the way to the terminus. A paracentric inversion or an unequal cross-over event may account for the observed difference between these species.

{open_quotes}Black Gold{close_quotes} leads to new structural interpretation, Northern Sangre de Cristo Mountains/Northeast San Luis Basin  

SciTech Connect

In the course of exploring for gold along the east margin of the Rio Grande Rift (northern Sangre de Cristo Mountains and northeastern San Luis Basin) live Cretaceous oil was discovered in fractured Precambrian gneiss in 25 of 42 shallow drill holes. Geologic mapping located two outcrops of Mesozoic sediments along the west flank of the Sangre de Cristo Mountains. Mancos Shale, Dakota Group and Morrison Formation sediments were identified from 17 drill holes. These are the first known occurrences of Mesozoic sediments in the area. Previous investigations had concluded that the Mesozoic section eroded from the San Luis uplift during the Laramide. Surface and subsurface geologic data was integrated with gravity, magnetic and seismic surveys for a new structural interpretation. The San Luis Basin is separated from the mountains by an intermediate block and the main basin-bounding fault is three miles west-southwest of the mountain front. A major low-angle, normal fault or detachment fault is related to Miocene rifting. A thick section of Mesozoic sediments are interpreted to be present in the hanging wall of this low angle fault. Buried and thermally matured in a Laramide intermountane basin, these sediments are likely the source of the present day oil found in Precambrian rocks.

The {open_quotes}ASR{close_quotes} story where we are and how we got there: A history of Sandia National Laboratories maintenance employee safety committee  

SciTech Connect

The Area Safety Representative (ASR) Team is an employee based safety committee that was originated in the latter part of 1994. It was introduced by the Operations and Engineering Center ES&H Coordinator who had heard about an employee based safety program implemented at the EG&G Corporation. This information was the first step in creating Sandia`s Maintenance `Area Safety Representative` (ASR) Program. An advertisement went out from the ES&H Coordinator to all the Maintenance Organizations asking for individuals who would be interested in performing as a volunteer safety representative for their section. The interest was moderate but effective. The committee consisted of one volunteer from each of the working sections within the Maintenance Organization, e.e., HVAC Mechanics, Electricians, Millwrights, Plumbers, Sheetmetal Workers, High-Voltage Technicians, a Union Representative, and representatives from the Operations Group that manage sub-contracted personnel. During the past year, organizational changes have brought about the addition of representatives to include the Planners and the Custodians. The original committee members were enrolled in a 30-hour OSHA Voluntary Compliance Outreach Course. This information provided the members with a broad overview of the Safety Guidelines set forth by OSHA for themselves and their coworkers. It is to be noted that this is an employee based safety team. There are no supervisors or managers on the committee but their attendance is always welcomed at the ASR meetings.

{open_quotes}A behavioral-based segmentation methodology the next step beyond classify{close_quotes} update...update...update  

SciTech Connect

Entergy Services, Inc., along with SDR, Inc., developed a market segmentation model for Entergy`s residential end-use customer database. This model is driven by a blending of behavioral and attitudinal variables taken from Entergy`s Marketing Information System (MKIS), Donnelley data and Entergy CLASSIFY{trademark} response data. After considerable effort, seven segments were identified which exhibit behavioral and attitudinal differentiation. The reliability of predicting segment membership is approximately 88% overall and 75% for the lowest group. This is compared to the project prediction criteria set at 75%/70% (i.e., correctly predict 75% of the holdout sample with no one group under 70% correct prediction). The purpose of this segmentation strategy is to market tailored offerings to specific segments, thereby improving customer satisfaction while reducing marketing costs. In the fourth and final phase of the project, the segmentation model will be tested by using actual sales data and by collecting new customer preference data. Once this phase is completed, residential program offerings can be developed or modified to best suit the targeted segment.

Accident analysis of railway transportation of low-level radioactive and hazardous chemical wastes: Application of the /open quotes/Maximum Credible Accident/close quotes/ concept  

SciTech Connect

The maximum credible accident (MCA) approach to accident analysis places an upper bound on the potential adverse effects of a proposed action by using conservative but simplifying assumptions. It is often used when data are lacking to support a more realistic scenario or when MCA calculations result in acceptable consequences. The MCA approach can also be combined with realistic scenarios to assess potential adverse effects. This report presents a guide for the preparation of transportation accident analyses based on the use of the MCA concept. Rail transportation of contaminated wastes is used as an example. The example is the analysis of the environmental impact of the potential derailment of a train transporting a large shipment of wastes. The shipment is assumed to be contaminated with polychlorinated biphenyls and low-level radioactivities of uranium and technetium. The train is assumed to plunge into a river used as a source of drinking water. The conclusions from the example accident analysis are based on the calculation of the number of foreseeable premature cancer deaths the might result as a consequence of this accident. These calculations are presented, and the reference material forming the basis for all assumptions and calculations is also provided.

SSC 17-meter dipole magnet DD000Z test results and investigation of coil failure: The report of the {open_quotes}Z{close_quotes} Committee  

SciTech Connect

Following the failure of the lower inner coil of magnet DD000Z on November 3, 1987, a committee was formed on November 11 and given the following charges: `To review the events leading up to and including the failure of the coils of magnet DD000Z. The intent of the review will be to determine the cause of the failure and to make recommendations to reduce the likelihood of such failures in the future. Given the fact that this is the first long magnet to be disassembled, the committee may uncover leads which point to other opportunities for improvement. The committee should follow up on these leads. The committee should prepare a plan to serve as an initial guide for the disassembly and provide guidance as the disassembly progresses.` The committee held its first meeting at FNAL on 17 and 18 Nov to review the record of events leading up to the failure and to establish an initial disassembly procedure. This was followed by further meetings at FNAL, BNL, and CDG, leading to this final report. Committee activities included interviewing personnel who had been involved in the design, assembly and testing of DD000Z, reviewing all documents relating to the magnet and its failure, and participating in and providing guidance during the disassembly. The intention of the committee was to report factual findings, to consider well founded hypotheses, not to consider conjecture and to avoid speculation.

Augmented Computer Exercise for Inspection Training (ACE-IT) - an interactive training tool for {open_quotes}challenge inspections{close_quotes} under the chemical weapons convention  

SciTech Connect

The on-site inspection provisions in many current and proposed arms control agreements require extensive preparation and training on the part of both the Inspection Teams and the Inspected Parties. Current training techniques include lectures, table-top inspections, and practice inspections. The Augmented Computer Exercise for Inspection Training (ACE-IT), an interactive computer training tool, increases the utility of table-top inspections. Under the Chemical Weapons Convention (CWC) challenge inspections are short-notice inspections that may occur anywhere, anytime, and with no right of refusal. The time interval between notice of intent to inspect a facility and the arrival of inspectors at the facility may be as short as 72 hours. Therefore, advance training is important. ACE-IT is used for training both the Inspection Team (inspector) and the Inspected Party (host) to conduct a hypothetical challenge inspection under the CWC. An exercise moderator controls the exercise. The training covers all of the events in the challenge inspection regime, from initial notification of an inspection through post-inspection activities. But the primary emphasis of the training tool is on conducting the inspection itself, and in particular, the concept of managed access. Managed access is used to assure the inspectors that the facility is in compliance with the CWC, while protecting sensitive information that is not related to the CWC.

Ferric complexes as catalysts for {open_quotes}Fenton{close_quotes} degradation of 2,4-D and metolachlor in soil  

SciTech Connect

Fenton-type reactions of hydrogen peroxide with Fe compounds generate bydroxyl radical (OH{center_dot}) or other reactive species and are potentially useful for degrading organic contaminants in soil. The use of simple Fe salts is limited, however. This study investigated certain pH 6-soluble Fe(III) complexes (Fe-L, where L is an organic tigand) as catalysts for degradation of herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and metolachlor (2-chloro-N-[2-ethyl 6-methylphenyl]-N-[2-methoxy-l-methylethyl]acetamide). Reactions were carried out in 1:1 aqueous suspensions of a topsoil (15.7 g kg{sup -1} organic C) at the natural pH of 5.7 with herbicides at concentrations representative of a spill (2-3 g kg{sup -1} about 0.01 mol kg{sup -1}). The two herbicides had contrasting sorption behavior in that 2,4-D was mostly in solution, whereas metotachlor was mostly sorbed. The best results were obtained using Fe-nitrilotriscetate (NTA) or Fe-hydroxyethyleniminodiacetate (HEIDA) at 0.01 mol kg-{sup -1} and [H{sub 2}O{sub 2}]{ge} 0.5 mol kg{sup -1}. The gallic acid complex was less effective. In 3 h,{sup 14}C-labeled 2,4-D was quantitatively dechlorinated and partially (15-30%) converted to {sup 14}CO{sub 2}: metolachlor was 93% transformed and 29% dechlorinated. Controls using free ligand plus peroxide or peroxide alone gave little or no reaction. Fe-L + H{sub 2}O{sub 2} was superior to the Fenton reagent itself (Fe{sup 2+} + H{sub 2}O{sub 2}). The results of this study demonstrate that relatively mild chemical oxidation can be effective for remediation of certain contaminants in soil 23 refs., 2 figs., 6 tabs.

A progress report on the LDRD project entitled {open_quotes}Microelectronic silicon-based chemical sensors: Ultradetection of high value molecules{close_quotes}  

SciTech Connect

This work addresses a new kind of silicon based chemical sensor that combines the reliability and stability of silicon microelectronic field effect devices with the highly selective and sensitive immunoassay. The sensor works on the principle that thin SiN layers on lightly doped Si can detect pH changes rapidly and reversibly. The pH changes affect the surface potential, and that can be quickly determined by pulsed photovoltage measurements. To detect other species, chemically sensitive films were deposited on the SiN where the presence of the chosen analyte results in pH changes through chemical reactions. A invention of a cell sorting device based on these principles is also described. A new method of immobilizing enzymes using Sandia`s sol-gel glasses is documented and biosensors based on the silicon wafer and an amperometric technique are detailed.

Mental retardation in a child with a {open_quotes}de novo{close_quotes} deletion of terminal 14q and a family history of dyslexia  

SciTech Connect

A couple presented for prenatal diagnosis for advanced maternal age. A review of the family history revealed that their elder daughter was mentally retarded while their second daughter was of normal intelligence. The father and his brother were both dyslexic. The paternal grandmother had lost three pregnancies, all female. The elder daughter had been fully assessed in the past, but no diagnosis had been made. During her first few years, she was frequently ill and failed to thrive. A developmental assessment at age 5 years concluded that she was moderately mentally retarded. She was minimally dysmorphic. DNA testing for fragile X and urine amnio acids, organic acids and metabolic screen were negative. Chromosome and FISH analyses revealed a satellited 14q with a deletion of 14q32.3. Parents did not show the karyotypic changes, but FISH studies on them and the dyslexic uncle are pending. A molecular work-up of chromosome 14 in this family is also in progress. In this child, the phenotype is probably related to the cytogenetic findings. The information about 14q terminal deletions in the literature is limited but a fairly consistent phenotype, which is slightly different from ring 14, is emerging. This is more obvious in infants that in older children. The family history of dyslexia could be unrelated to our patient`s findings but it is also possible that there is a recessive gene for dyslexia in this family which maps to 14q32.3. The current molecular map of this area provides no answer to this question. Genes mapped to 14q3.3 include the alpha-1-antitrypsin gene, the brain component of creative kinase (CKB) and the immunoglobulin heavy chain genes. Loss of heterozygosity of 14q has been associated with end stage human neuroblastoma and colonic neoplasia.

Experience with optical {open_quotes}PT`s and CT`s{close_quotes} at 500kV, for metering and relaying  

SciTech Connect

For most of this century, the measurement of transmission voltages and currents have been accomplished with magnetic or capacitive devices that transform primary power system quantities to 115 and 67 volts and 5 amps, secondary. The secondary currents are capable of transmitting 5 kW of power during system transients that demand long runs of No. 12 wire to reduce burden and prevent saturation. This cabling is expensive to purchase and install requiring substantial design expertise to provide the electrical isolation. Also, the failure of these devices is often explosive, creating unplanned outages and subjecting personnel to potential injury when failures occur. This report discusses the evaluation of 500 kV optical voltage and current transducers that are a part of the Advanced Substation Project. One objective of the project is to incorporate all substation control, protection and metering on one optical communication bus. All substation functions and equipment will be remotely accessed via telephone modems or dedicated communications. The overall project goal is to reduce the cost of substation equipment and design. Operation and maintenance schedules will be reduced with equipment that is self diagnostic, automatically signaling component failures as they occur.

24th WRSM panel discussion: {open_quotes}The role of research in nuclear regulation: The case of qualified importers{close_quotes}  

SciTech Connect

Scientific knowledge and technological maturity are needed to establish regulatory requirements, what also needs talent and skills. Scientists are rarely interested in regulation and regulators not always are closely connected to scientific research. This has created gaps in regulations, mainly within qualified importers. A qualified importer, in the sense of this presentation, is a country who has acquired nuclear power plants from more technologically advanced exporters but with an increasing participation of its own industry and institutions in the design, construction, component manufacture and assembly of such nuclear power plants and is fully responsible for the operation of the nuclear units and the corresponding fuel cycle. These countries have also a long standing and independent nuclear regulatory organization and the corresponding technical body. Spain is a qualified importer. In the case of Spain, it originally adopted the codes and regulations of the UE which it was a member of, as well as the codes and standards of the country from which their reactors were produced. Since Spain added KWU plants they even went to German regulations. Plant operation rested with Spain. As problems began to appear in operating plants, local research projects were funded to study the problems, aimed at immediate solutions, but also providing training for local personnel in addition to information of use for regulators. Spain has participated in many joint research projects, which have trained people, and given confidence to Spaniards involved in science and regulations. Qualified importers, like Spain, participate in research, even though it may not translate itself into regulation. Such participation will always serve to give self-confidence and independence to regulators and licensees, to better understand the adopted regulations of the most advanced countries and to solve specific problems.

Plant and environment interactions: Growth and yield response of commercial bearing-age {open_quote}Casselman{close_quote} plum trees to various ozone partial pressures  

SciTech Connect

Nursery stock of plum (Prunus salicina Lindel., cv. Casselman) was planted 1 Apr. 1988 in an experimental orchard at the Univ. of California Kearney Agricultural Center near Fresno, CA. Trees in this study were enclosed in open-top fumigation chambers on 1 May 1989, and exposed to three atmospheric ozone partial pressures (charcoal filtered air, ambient air, and ambient air + ozone) during the 1989 through 1992 growing seasons (typically 1 Apr. - 1 Nov.). A nonchamber treatment plot was used to assess chamber effects on tree performance. This study details the results of the exposures during the initial commercial bearing period (1991 through 1993) in this orchard. The mean 12-h (0800-2000 h Pacific Daylight Time [PDT]) ozone partial pressures during the experimental periods in the charcoal filtered, ambient, ambient + ozone, and nonchamber treatments averaged 0.031, 0.048, 0.091, and 0.056 {mu}Pa Pa{sup {minus}1} in 1991 and 1992, respectively. Fruit number per tree decreased as atmospheric ozone partial pressure increased from the charcoal filtered to ambient + ozone treatment, significantly affecting yield. Yield of plum trees averaged 23.6, 19.8, 13.7, and 17.9 kg tree{sup {minus}1} in 1991 and 1992 in the charcoal filtered, ambient, ambient + ozone, and nonchamber treatments, respectively. Only one out of the five original treatment plots was exposed to ozone treatments during the 1993 growing season. Yield of plum trees in this single replicate in 1993 was reduced by increased atmospheric ozone partial pressure. Yield of plum trees in the four remaining unexposed treatment plots in 1993 was 16.7, 17.9, and 16.0 kg tree{sup {minus}1} in the previous charcoal filtered, ambient, and ambient + ozone treatments respectively. The similarity in yield of the post-chamber treatments indicates that a change in air quality in the current growing season can affect yield of Casselman plum trees. 26 refs., 6 figs., 4 tabs.

The ability to reliably and accurately locate and survey objects without physically occupying them is the key to the productivity of the FLI-MAP{trademark} laser mapping system. This advanced technology system incorporates OTF Kinematic GPS, GPS-aided attitude, and a reflectorless laser range-finding sensor into a complete remote sensing survey platform. The FLI-MAP system is a helicopter-based scanning system capable of collecting up to 8000 geo-referenced data points per second. Key parameters of existing electric transmission lines are calculated based upon the geographic data collected by FLI-MAP, meteorological data, and power flow data collected during the survey. The affect on conductor clearances is analyzed under varying conductor temperatures, power flow, and meteorological conditions to determine the ultimate capacity of the existing transmission line. This paper presents the FLI-MAP system, the technologies it exploits, and the use of such a system for electric transmission line corridor surveys and analyses. 4 refs., 5 figs.

SciTech Connect

Today, there is a strong public demand for environmental and energy efficiency in the built environment. According to EPA for at least the past three or four years, there has been one hundred twenty billion dollars annually spent on the environment. This is being done because there are some 30 federal statutes relating to environmental protection. On average there are about 10 separate statutes at every state level. This legislation has taken since the 1970`s to accumulate. They have been enacted because of strong public demand for environmental protection. Public opinion polls have shown for the last five years that support for environmental protections exceeds 90%. It is a very popular national commitment. There are no more debates over whether we need to stop pollution. Those have long gone, and this is being recognized by the building community. We need to recognize that there is a public demand for these issues to be evaluated, discussed and resolved. Buildings, productivity, energy and environmental efficiency are a huge investment in the country, and it is thought that a deliberative debate with decisions on a consensus basis in an expedited manner, is going to be very effective.

Summary evaluation of the video, {open_quotes}Transportation of radioactive and hazardous materials: Safety for all concerned{close_quotes}  

SciTech Connect

Outreach materials are often developed and distributed without evaluation of their effectiveness. This report provides a glimpse of the effectiveness of one of the US Department of Energy`s videos on transportation of radioactive and hazardous materials. Data from a survey developed by Modern Talking Picture Service, Inc. are summarized. This survey was sent to recipients of the video at three to six weeks after they had received and viewed the video. The response rate is unknown; hence, the results suggest the range of perspectives on the video, rather than the representativeness of those perspectives. The results are also limited by incomplete responses to the survey. Most respondents were middle school and high school teachers who resided throughout the country. Respondents used the video in nearly all school subjects. Most respondents indicated that the video was fairly good and appreciated the factual information, although some saw it as propaganda. Respondents indicated that they would like additional information on hazardous wastes, nuclear power, and transportation. The test crashes were mentioned as a highlight of the video. Recommendations for revising the video and survey are included.

You won`t find these leaks with a blower door: The latest in {open_quotes}leaking electricity{close_quotes} in homes  

SciTech Connect

Leaking electricity is the energy consumed by appliances when they are switched off or not performing their principal functions. Field measurements in Florida, California, and Japan show that leaking electricity represents 50 to 100 Watts in typical homes, corresponding to about 5 GW of total electricity demand in the United States. There are three strategies to reduce leaking electricity: eliminate leakage entirely, eliminate constant leakage and replace with intermittent charge plus storage, and improve efficiency of conversion. These options are constrained by the low value of energy savings-less than $5 per saved Watt. Some technical and lifestyle solutions are proposed. 13 refs., 1 fig., 2 tabs.

The Lasagna project is the first of what we expect will be several large cooperative projects between industry consortia and government to develop improved remediation technologies. In 1992, Monsanto Company began contacting other major corporations to see if they were experiencing similar difficulties in applying cost-effective, or even workable technologies for industrial site remediation. Both General Electric and DuPont were early participants in the effort to develop a meeting with the EPA to discuss technical problems faced in cleanup, research needs, and ways to accelerate development of more cost-effective techniques. This paper provides some background on how this cooperative process came to reality, what the Lasagna process is and how the cooperative arrangements and financing are structured.

Safe and economical operations with fissile materials require knowledge of the subcriticality of configurations that arise in material processing, storage, and transportation. Data from critical experiments have been a principal source of information with which to establish safety margins.

Calculation and classification of the radioactive waste inventory in the structural components of the {open_quotes}IGNITOR{close_quotes} compact ignition torus  

SciTech Connect

The choice of structural material for future fusion plants is based on a multiplicity of considerations. While these materials should possess adequate thermo-mechanical properties they should also satisfy certain criteria with regard to the eventual treatment and disposal of radioactive wastes. From this point of view it is important to have a knowledge of the radioactive inventory produced in the structural materials of a nuclear fusion plant during its operation and the evolution of this radioactivity in time. In this work the authors have calculated the radioactive inventory and decay heat produced in the structural components of the projected fusion plant IGNITOR-ULT due to D-T neutrons produced in the plasma. In particular, the dose rate and the heat production in the following materials have been studied: graphite in the first wall, INCONEL 625 in the vacuum vessel and copper in the magnet. All the results presented are for the outboard plasma components.

Characterization of printing and laser trimming of DuPont 2000 series resistors on DuPont 951 {open_quotes}Green Tape{trademark}{close_quotes}  

SciTech Connect

DuPont 2000 series resistors were reviewed and found to come closest to our requirement of 1% resistor tolerance over the expected 30-year life of our products. The evaluation performed involved the characterization of both the printing and trimming processes. The printing process was characterized for firing temperature print thickness, print direction, resistor geometry and encapsulant effect. Laser trimming was characterized by first finding an operating envelope and then selecting an operating point. The envelope was located by varying the trimming parameters and determining their acceptability to electrical and visual criteria. Samples from both the envelope and operating point were environmentally conditioned The conditioning included thermal shock temperature cycle, 1000-hour temperature aging, 1000-hour humidity aging, and a simulated gold/tin solder reflow.

Bananas, allegators, and {open_quotes}hot rocks that shoot ghost bullets{close_quotes}: Sitings along the trail to an MRS  

SciTech Connect

Building new electric power facilities in a community used to be greeted warmly by that community. However, during the 20 year hiatus in power plant siting, opposition to siting just about every kind of facility has grown. The challenge to site a monitored retrievable storage (MRS) facility for the temporary storage of commercial spent nuclear fuel is monumental but not insurmountable. The safety and environmental records on commercial spent-fuel storage to date are impressive. This article gives an overall perspective on siting an MRS. Topics covered include the following: the Nuclear waste Policy Act; the Nuclear Waste Negotiator; DOE`s Feasibility Grand`s program; Looking back at past efforts; using portable information in some areas; and where the efforts go now in trying to site a MRS.

Blogs and Twitter in medical publications: too unreliable to quote, or a change waiting to happen?  

PubMed

With the ubiquitous connectivity offered by the Internet, social media sites (like Twitter and Facebook) and personal publishing platforms (blogs) are proliferating rapidly. In this new, evolving scenario of social media, these tools become an important medium to disseminate information at a lightning speed. However, the conventional medical publication model is less than eager to regard them as equivalent to traditional modes of information dissemination. In this article we examine the role played by social media as a critic of the medical publication system, and how it acts as a safeguard by building a platform for post-publication peer review.

Ulysses{close_quote} rapid crossing of the polar coronal hole boundary  

SciTech Connect

The Ulysses spacecraft crossed from the slow dense solar wind characteristic of the solar streamer belt into the fast, less dense flow from the northern polar coronal hole over a very short interval (several days) in late March 1995. The spacecraft, which was at 1.35 AU and {approximately}19{degree} north heliographic latitude, moving northward in its orbit, remained in the fast solar wind from then through summer 1996. This boundary crossing is unique in that the combination of the spacecraft motion and rotation of the structure past the spacecraft caused Ulysses to move smoothly and completely from one regime into the other. In this study we examine this crossing in detail. The crossing is marked by a region of enhanced pressure, typical of stream interaction regions, which extends {approximately}2{times}10{sup 7}km across. We find that the transition between the slow and fast regimes occurs on several temporal, and hence spatial, scales. On the shortest scale ({lt}8{times}10{sup 4}km) the stream interface is a tangential discontinuity where the proton and core electron densities and ion and electron pressures all drop while the magnetic pressure jumps to maintain a rough pressure balance. The alpha to proton ratio also jumps across the stream interface to reach the comparatively constant polar hole value of {approximately}4.3{percent}. On larger scales (a few {times}10{sup 6}km) the proton and alpha temperatures rise to their high-speed wind values. Finally, on the largest scale ({approximately}10{sup 8}km) the solar wind speed ramps up from {approximately}400kms{sup {minus}1} to {approximately}750kms{sup {minus}1}, typical of polar hole flows. While it seems likely that the stream interface maps back to a sharp boundary near the Sun, the large region of increasing flow speed suggests that there is also an extended gradient in solar wind source speed close to the Sun. {copyright} 1998 American Geophysical Union

Quoting A.T. Still with rigor: an historical and academic review.  

PubMed

The statements of Andrew Taylor Still, MD, DO, abound within the osteopathic literature. However, Still is sometimes misquoted, and corresponding references to his quotations are occasionally incomplete or inaccurate. There are several reasons why these errors continue to occur, including confusion surrounding the copyright dates and multiple editions of his books. In addition, less reliable, secondary sources of Still's words are often used instead of primary sources. To help resolve these problems, the author proposes 3 solutions. A list of Still's known published books, including the correct copyright date of The Philosophy and Mechanical Principles of Osteopathy, is provided. The disadvantages associated with using the 2 most popular secondary sources of Still's work are described. Guidelines from the 10th edition of the AMA Manual of Style are reviewed to assist authors, educators, and students in accurately citing material from older sources, such as Still's writings.

Mitigation of atmospheric carbon emissions through increased energy efficiency versus increased non-carbon energy sources: A trade study using a simplified {open_quotes}market-free{close_quotes} exogenously driven model  

SciTech Connect

A simplified model of global, long-term energy use is described and used to make a `top-level` comparison of two generic approaches for mitigating atmospheric carbon emissions: (a) those based on increased energy efficiency; and (b) those based on increased use of reduced- or non-carbon fuels. As approximate as is the model, first-order estimates of and trade offs between increasing non-carbon generation capacities (e.g., supply-side solutions) versus energy-use efficiency (e.g., demand-side solutions) to stem atmospheric carbon accumulations can be useful in guiding more elaborate models. At the level of this analysis, both the costs of abatement and the costs of damage can be large, with the formation of benefit-to-cost ratios as a means of assessment being limited by uncertainties associated with relating given climatic responses to greenhouse warming to aggregate damage cost, as well as uncertainties associated with procedures used for multi-generation discounting of both abatement and damage costs. In view of uncertainties associated with both supply-side and demand-side approaches, as well as the estimation of greenhouse-warming responses per se, a combination of solutions seems prudent. Key findings are: (a) the relative insensitivity of the benefit-to-cost ratio adopted in this study to supply-side versus demand-side approaches to abating atmospheric carbon-dioxide emissions; (b) the extreme sensitivity of damage costs, abatement costs, and the related benefit-to-cost ratios to the combination of discounting procedure and the (time) concavity of the function used to relate global temperature rise to damage costs; and (c) no matter the discounting procedure and/or functional relationship between average temperature rise and a damage cost, a goal of increased per-capita gross world product at minimum damage suggests action now rather than delay.

Magnetic susceptibility studies as a function of temperature provide convincing evidence of two ruthenium (III) centers with no magnetic interaction between them. The catalytic activity of these compounds was tested for the oxidation of alkenes and alkanes using aqueous 30% hydrogen peroxide and 70% tert-butyl hydroperoxide as oxidants. The alkene oxidation proceeded in high reactivity and moderate selectivity to the epoxide product using 30% H{sub 2}O{sub 2}. Kinetic profiles as well as UV-vis and IR spectra before, during and after the reaction indicate that the catalysts are stable throughout the reaction. Formation of epoxides rather than ketonization in the reaction of terminal alkenes as well as low reactivity with iodosobenzene indicates that the reaction is tungsten centered and not noble metal centered. Oxidation of alkenes with tert-butyl hydroperoxide gave mostly allylic oxidation and/or addition of tert-butyl alcohol to the double bond. Oxidation of cyclic alkanes such as cyclohexane and adamantane was successful with tert-butyl hydroperoxide with catalytic activity 10 times higher than previously found for transition metal substituted Keggin compounds. Ratios of hydroxylation of adamantane at tertiary vs secondary positions indicates different active species in the palladium-, platinum-, and ruthenium substituted-polyoxometalates.

At birth they were small for date, their length is now below the 10th centile. Chromosome analysis demonstrated a nearly pure trisomy 1q42{r_arrow}qter in both patients due to unbalanced segregation of a paternal reciprocal balanced translocation 46,XY,t(1;15) (q42;p11). This is the second report of a nearly pure trisomy 1q42{r_arrow}qter. When comparing the manifestations of our patients with those of other reported cases we conclude that the most characteristic clinical manifestations of this syndrome are macrocephaly, prominent forehead, micro/retrognathia, large fontanelle, intrauterine growth retardation, postnatal growth retardation, and mental retardation. 56 refs., 4 figs., 1 tab.

SciTech Connect

The Fast-On-orbit Recording of Transient Events (FORTE) satellite is the second satellite to be developed and flown by Los Alamos National Laboratory and is scheduled to be launched August, 1997 by a Pegasus XL rocket. FORTE follows in the footsteps of the ALEXIS satellite in utilizing a very small operations crew for mission operations. Partially based upon the ALEXIS automation and World Wide Web (WWW) usage for data dissemination, FORTE began at an early stage of ground processing to use the web as a repository of information about all aspects of the satellite. Detailed descriptions of the various satellite and experiment components, cable diagrams, integration photographs as well as extensive test data have all been compiled into a single site as a means of archiving the data at a single location. In this manner, it is readily available during times of ground testing, ground station operation training as well as anomaly resolution. Small satellites usually require extensive effort to optimize operation under minimal resources. For the FORTE satellite, a unique planning tool has been developed over the past 2 years which balances the various resources of the satellite (power, memory, downlink, on board command buffer, etc.) to provide the maximum data acquisition. This paper will concentrate on a description of both the extensive web interface and the planning tool. 6 refs.

US Geological Survey Committee for the Advancement of Science in the Yucca Mountain Project symposium on {open_quotes}Fractures, Hydrology, and Yucca Mountain{close_quotes}: Abstracts and summary  

SciTech Connect

The principal objective of this symposium is to review the available information on fractured/faulted terrains in terms of a coherent hydrogeologic model of ground-water fluid flow and transport, particularly as it pertains to the Yucca Mountain region. This review addresses the influence and significance of fractures on ground-water flow and the transport of conservative-species solutes within the context of the hydrogeologic setting of the Yucca Mountain area. The relations between fluid flow and fractured or faulted host rock are examined integrally from information on geologic, seismologic, hydrologic, and geomechanical properties of the system. The development of new hydrogeologic approaches that incorporate information from this integrated database are contrasted with more standard approaches toward understanding flow in fractured reservoirs. Ground-water flow in both the unsaturated zone and the saturated zone are considered. The application of various models of flow is addressed, examples include porous-media equivalent and discontinuum fracture-network models. Data and interpretations from the Yucca Mountain area are presented to establish a context for information exchange. The symposium includes discussions relevant to technical considerations for characterizing the Yucca Mountain area hydrogeology. On the basis of these discussions, CASY has compiled this document in order to formally summarize the proceedings and communicate recommendations for future directions of research and investigation.

Field testing an OREX{reg_sign} based {open_quotes}point of generation{close_quotes} low-level radioactive waste reduction program at FP&L`s St. Lucie Plant  

SciTech Connect

Nuclear power facilities, both commercial and government operated, generate material called Dry Active Waste (DAW). DAW is a by-product of maintenance and operation of the power systems which contain radioactive materials. DAW can be any material contaminated with radioactive particles as long as it is not a fluid, typically: paper, cardboard, wood, plastics, cloth, and any other solid which is contaminated and determined to be dry. DAW is generated when any material is exposed to loose radioactive particles and subsequently becomes contaminated. In the United States, once a material is contaminated it must be treated as radioactive waste and disposed of in accordance with the requirements of Title 10 of the Code of Federal Regulations. Problems facing all commercial and non-commercial nuclear facilities are escalating costs of processing DAW and volumetric reduction of the DAW generated. Currently, approximately 85% of all DAW generated at a typical facility is comprised of anti-contamination clothing and protective barrier materials. Facilities that generate low-level radioactive waste need to dramatically reduce their waste volumes. This curtailment is required for several reasons: the number of radioactive waste repositories now accepting new waste is limited; the current cost of burial at an operating dump site is significant. Costs can be as high as $4,000 for a single 55 gallon drum; the cost of burial is constantly increasing; onsite storage of low-level radioactive waste is costly and results in a burial fee at plant decommissioning.

Speaking of Science. Notable Quotes on Science, Engineering, and the Environment by Jon Fripp, Michael Fripp, and Deborah Fripp  

NASA Astrophysics Data System (ADS)

Should you buy this book? Well, why not! It's not something that one is going to read from cover to cover, but it is nice to have it handy for those times when a quotation is needed. For example, if your Department Head schedules a meeting that interferes with your plans to play golf, dismiss him or her with Freeman Dyson's "We have been suffering from a surfeit of committees. Committees do harm merely by existing"; or if a future M.D. in your undergraduate course complains about a grade, use this riposte (but don't forget to duck!) from Lewis Thomas "The influence of the modern medical school on liberal arts education in this country over the last decade has been baleful and malign, nothing less." Both of these, by the way, come from my own collection, not from the one under review. Maybe I, too, should compile a book of quotations?

Preliminary results of the correlation between ion concentrations in rainwater samples and atmospheric back trajectories as a part of the study {open_quotes}impact to acid rain in the deterioration of Mexican Maya monuments{close_quotes} (project Conacyt-UNAM: 0128T9106)  

SciTech Connect

The environmental Pollution Section at the Center of Atmospheric Sciences, National Autonomus University of Mexico (UNAM), has been conducting a research project on their potential of impact of acid rain on the Mexican Maya monuments since 1993. As a part of such study, 49 rainwater samples were collected during the years 1994 through 1995 at the Puerto Morelos Oceanographic Station Located close to the Tulum Maya ruins in the State of Qintana Roo. The rain water samples were collected using an automatic rain collector. After the rain event, the water samples were transferred to clean Nalgene bottles. The bottles were stored under refrigeration prior to their shipment to the UNAM laboratory in Mexico City. Concentrations of anions Cl{sup -}, NO{sup -}{sub 3}, and SO{sup 2-}{sub 4} and cations Na{sup +}, NH{sup +}{sub 4}, K{sup +}, Mg{sup 2+} an Ca{sup 2+} were determined by the High Pressure Ion Chromatographic Procedure. The pH of samples was measured in the laboratory. Also, wind back upper trajectories which arrived to the Puerto Morelos are at the same date of each rain event, were calculated using the GMCC atmospheric trajectory program at NOAA. A thorough analysis on the relations between anions and cations is made and preliminary correlations of these results with the calculated long range trajectories are explored in order to find the possible origin of the event.

SciTech Connect

The title compound was prepared at 360{degrees}C, starting from Nb{sub 2}O{sub 5} and NH{sub 4}H{sub 2}PO{sub 4}. The orthorhombic unit-cell parameters were determined by electron and X-ray diffractions: a = 12.0819 (2) {angstrom}, b = 8.6848 (1) {angstrom}, c = 8.7452 (1) {angstrom}, space group Pbcn. Reitveld refinements from X-ray powder diffraction data, chemical analyses, and the measured density show that the basic structure consists of a three-dimensional framework of the Sc{sub 2}(WO{sub 4}){sub 3} structure type, with NbO{sub 6} octahedra and PO{sub 4} tetrahedra sharing corners, and that both Nb and P vacancies occur. The actual formula is close to Nb{sub 2-x}P{sub 3-y}O{sub 12}. Comparative spectroscopic studies of the title compound and of Nb{sub 3}(NbO){sub 2}(PO{sub 4}){sub 7} confirm the occurrence of the vacancies, and thus an important local variation of the bond lengths near the defect sites. The presence of small amounts of H and N in the structure is discussed. Upon heating in air, the structure is preserved up to 900{degrees}C. The so-called {epsilon}-NbOPO{sub 4} has the same basic structure, and its existence seems questionable.

Heterogeneity, geostatistics, horizontal wells, and blackjack poker  

SciTech Connect

This paper presents data on more than one thousand horizontal wells specifically comparing their hydrocarbon production performance to offsetting vertical wells. The data are striking, revealing an approximate log-normal distribution of Productivity Improvement Factors (PIFs). This distribution is ascribed primarily to geological heterogeneities compounded by mechanical drilling and completion effects. H-wells in conventional reservoirs show a mode or {open_quotes}most-likely{close_quotes} PIF just over 2, a median or {open_quotes}50/50 {close_quotes} PIF just over 3, and a mean or {open_quotes}average{close_quotes} PIF just over 4; with somewhat higher PIFs observed for heavy-oil h-wells and h-wells in heavily-fractured fields. The data also show an operator`s {open_quotes}expectation{close_quotes} should be based on the number of wells planned, with a larger number of wells yielding a higher {open_quotes}average{close_quotes} production per well. In some cases, it was possible to compare actual production results to those predicted by the operator. This also showed some rather startling results: though our {open_quotes}predictive models{close_quotes} appear quite accurate when averaged over several wells, the error expected for any individual h-well is greater than 50%! Some simple gaming examples show this size of error should be expected for almost any reservoir calculation (perhaps a better phrase is {open_quotes}reservoir estimate{close_quotes}).

That which does not kill us makes us stronger--does Nietzsche's quote apply to islets? A re-evaluation of the passenger leukocyte theory, free radicals, and glucose toxicity in islet cell transplantation.  

PubMed

In clinical islet transplantation, isolated islets are embolized into the liver via the portal vein (PV); however, up to 70% of the islets are lost in the first few days after transplantation (i.e., too quickly to be mediated by the adaptive immune system). Part of early loss is due to instant blood-mediated inflammatory reaction, an immune/thrombotic process caused by islets interacting with complement. We have shown that glucose toxicity (GT) also plays a critical role based upon the observation that islets embolized into the PVs of diabetic athymic mice are rapidly lost but, if recipients are not diabetic, the islet grafts persist. Using donor islets resistant to the ?-cell toxin streptozotocin, we have shown that intraportal islets engrafted in non-diabetic athymic mice for as little as 3 days will maintain normoglycemia when streptozotocin is administered destroying the recipient's native pancreas ?-cells. What is the mechanism of GT in ?-cells? Chronic exposure to hyperglycemia over-exerts ?-cells and their electron transport chains leak superoxide radicals during aerobic metabolism. Here we reinterpret old data and present some compelling new data supporting a new model of early intraportal islet graft loss. We hypothesize that diabetes stimulates overproduction of superoxide in both the ?-cells of the islet grafts and the endothelial cells lining the intraportal microvasculature adjacent to where the embolized islets become lodged. This double dose of oxidant damage stresses both the islets, which are highly susceptible to free radicals because of inherent low levels of scavenging enzymes, and the adjacent hepatic endothelial cells. This, superimposed upon localized endothelial damage caused by embolization, precipitates inflammation and coagulation which further damages islet grafts. Based upon this model, we predict that pre-exposing islets to sub-lethal hyperoxia should up-regulate islet free radical scavenging enzyme levels and promote initial engraftment; reinterpretation of 30 years old "passenger leukocyte" data and preliminary new data support this. Other data suggests that pre-exposure of recipients to hyperoxia could up-regulate antioxidant enzymes in the hepatic endothelium. The combination of both effects could markedly enhance early intraportal islet graft survival and engraftment. Finally, if our model is correct, current in vitro and in vivo tests used to test batches of harvested islets for viability and function prior to transplantation are poorly conceived (n.b., it is already well-known that results using these tests often do not predict clinical islet transplantation success) and a different testing paradigm is suggested.

Inferring Trade Direction from Intraday Data  

Microsoft Academic Search

This paper evaluates alternative methods for classifying individual trades as market buy or market sell orders using intraday trade and quote data. The authors document two potential problems with quote-based methods of trade classification: quotes may be recorded ahead of trades that triggered them, and trades inside the spread are not readily classifiable. These problems are analyzed in the context

Plume fluxes in clear and cloudy convective boundary layers  

SciTech Connect

From results of large-eddy simulations of the clear convective boundary layer and of a stratus-topped boundary layer, mean properties of [open quotes]plumes[close quotes] that consist of [open quotes]updrafts[close quotes] and [open quotes]downdrafts[close quotes] are determined. The plumes are defined locally by the sign of the vertical velocity or of moisture fluctuation or by a combination of both. As a further alternative, updrafts and downdrafts in which the vertical velocity magnitude exceeds certain threshold values are considered. The first two variants divide the motion field into two streams, whereas in the other variants [open quotes]environmental[close quotes] air forms a separate stream. The computed mean properties are in general agreement with existing measurements. From the results we compute mean vertical fluxes assuming [open quotes]top-hat profiles[close quotes] and compare these with the actual fluxes. It is shown that the most uniform flux approximation is obtained if the plume structure is classified in terms of vertical velocity w. For such [open quotes]w plumes,[close quotes] the top-hat profiles approximate about 60% of the actual fluxes if updrafts and downdrafts are distinguished with zero threshold values just according to the sign of the vertical velocity. A higher percentage is obtained with nonzero threshold values. 23 refs., 40 figs.

The Clean Air Act`s enforcement ace: An overview of EPA`s credible evidence rule  

SciTech Connect

The 1990 Clean Air Act ({open_quotes}CAA{close_quotes}) amendments included numerous provisions directing EPA to require owners or operators to conduct enhanced monitoring and to make compliance certifications. These provisions contained in both those Title V (Operating Permits) and Title VII (Enforcement) of those amendments. Section 503(b)(2) of the amended CAA requires at least annual certifications of compliance with permit requirements and prompt reporting of any deviations from such requirements. Section 114(a)(3) of the CAA requires EPA to promulgate rules on enhanced monitoring and compliance certifications. On October 23, 1993, EPA proposed its {open_quotes}enhanced monitoring{close_quotes} rule. The enhanced monitoring proposal also included the Conceptual approach of using {open_quotes}presumptively credible evidence{close_quotes} in enforcement actions. Further, this proposal also would have allowed the use of {open_quotes}credible evidence,{close_quotes} other than reference or compliance test data to establish noncompliance in an enforcement action. In approximately three weeks, EPA is scheduled to republish as a final rule, the credible evidence provisions of the original enhanced monitoring rule with apparently minor revisions. This paper briefly summarizes the history, status, and likely impact EPA`s {open_quotes}any credible evidence{close_quotes} ({open_quotes}ACE{close_quotes}) rule.

Mining landforms - A renewable energy development opportunity  

SciTech Connect

A {open_quotes}landforming{close_quotes} land development opportunity unique to metals mining is described. {open_quotes}Landforming{close_quotes}, wherein the earth`s surface is reconfigured with mining waste rock and tails for the capture of renewable energy, is proposed by the United States Bureau of Mines (USBM) to be ecologically acceptable and, in selected cases, economically superior to conventional mineral extraction, reclamation, and minesite abandonment practices. Landforming is primary land construction that uses mining waste and applies the principles of land overlay architecture. Landforms can be layered, shaped, and configured through the use of binders and plastic sheeting to the engineering specifications necessary for the support of physical structures and passage or retention of fluids. Landforms that are terraced and south facing (in the Northern Hemisphere) are an ideal mount for sun-tracking mirror (heliostat) arrays. In {open_quotes}blue sky{close_quotes}. solar-rich environments, the mirrors can be targeted on a common area to form a {open_quotes}solar furnace.{close_quotes} The heat generated at the focal point of the solar array can be used to flash generate steam and run a turbine electric generator. The solar steam power generation cycle coproducers distilled water that can be sprayed onto the surfaces of the landform to create {open_quotes}greenscape.{close_quotes} Waters not consumed or evaporated in the site greening process percolate into and are stored by the landform if it is underlain with plastic. The landform serves, in effect as a shallow aquifer. The terrace-landform development of mineral properties in remote, infrastructurally destitute areas creates renewable energy, sustainable, electric power-water {open_quotes}oases.{close_quotes} The landform development of mineral properties adjacent to metropolitan areas creates utilities expansions and recreational {open_quotes}greenspace{close_quotes} in areas of growing urban need.

ITER Building Design (D230-B), Task No. 28. Final report  

SciTech Connect

The International Thermonuclear Experimental Reactor (ITER) Project requires a set of buildings, each with its own distinct function, to support ITER`s mission. The Joint Central Team (JCT) has identified all the buildings in the set and has placed them in an efficient arrangement on the site. The JCT has developed a conceptual layout of each individual building. The buildings have been categorized into two main groups: (1) {open_quotes}Level 1 Buildings{close_quotes} which are on the construction schedule critical path and (2) {open_quotes}Level 2 Buildings{close_quotes} which, while important, are not on the critical path. The buildings are further categorized according to construction material, that is, {open_quotes}reinforced concrete{close_quotes} or {open_quotes}steel-frame on concrete slab{close_quotes}. This Report responds to the Project`s request to perform the initial structural steel design for all the {open_quotes}steel-frame on concrete slab{close_quotes} buildings. Of the twelve (12) {open_quotes}steel-frame on concrete slab{close_quotes} buildings, four (4) are Level 1 and eight (8) are Level 2 Buildings. This Report is a deliverable for the ITER Task Assignment entitled {open_quotes}ITER Buildings Design (D230-B){close_quotes}, also designated as Task No. 28. ITER U.S. Home Team Industrial Consortium members, Raytheon Engineers & Constructors (RE&C) and Stone & Webster Engineering Corporation (SWEC), teamed to perform Task 28. This task commenced in May 1995. It was performed in accordance with the design criteria specified by the ITER-JCT, San Diego Joint Work Site.

Segregation analysis of Alzheimer pedigrees: Rare Mendelian dominant mutation(s) explain a minority of early-onset cases  

SciTech Connect

Segregation analysis of Alzheimer disease (AD) in 92 families ascertained through early-onset ({le}age 60 years) AD (EOAD) probands has been carried out, allowing for a mixture in AD inheritance among probands. The goal was to quantify the proportion of probands that could be explained by autosomal inheritance of a rare disease allele {open_quotes}a{close_quotes} at a Mendelian dominant gene (MDG). Our data provide strong evidence for a mixture of two distributions; AD transmission is fully explained by MDG inheritance in <20% of probands. Male and female age-of-onset distributions are significantly different for {open_quotes}AA{close_quote} but not for {open_quotes}aA{close_quote} subjects. For {open_quotes}aA{close_quote} subjects the estimated penetrance value was close to 1 by age 60. For {open_quotes}AA{close_quotes} subjects, it reaches, by age 90, 10% (males) and 30% (females). We show a clear cutoff in the posterior probability of being an MDG case. 10 refs., 1 tab.

Financial constraints and CO{sub 2} tax in Eastern Europe: A modelling approach  

SciTech Connect

The four East European countries belonging to the {open_quotes}VISEGRAD{close_quotes} group (Poland, Czeck Republic, Slovakia, Hungary) want to join rapidly the European Union. They already benefit from some commercial advantages. Russia will not join the European Union but it also wants to benefit from some commercial relationships with Europe. It Is the reason why these countries in, particular the {open_quotes}VISEGRAD{close_quotes} group, have to respect some financial constraints; in the European Union the Maastricht Treaty requires the following criteria: about the same rates of inflation and Interest, stability of currency, budget deficit less than 3% of G.D.P. and a public debt stock less than 60% of G.D.P. The first objective of the economies {open_quotes}in transition{close_quotes} is to introduce the conditions of a market-oriented economy: price freedom, removal of subsidies, privatization, competition and efficiency incentives. The state itself must respect economic rules, in particular to avoid an excess budget deficit. The privatization process we may observe today is partly due to the search of efficiency incentives; it is largely due to a financial constraint: to avoid the {open_quotes}snowball effect{close_quotes} of public debt. Improving efficiency in the energy sector is possible through {open_quotes}fair{close_quotes} energy pricing, which would allow to cut public subsidies to this sector.

Enhancement of computer program SPECTRAN to provide optional synthesis of 1/12 octave-band and critical-band spectra from 1/3 octave-band spectra  

SciTech Connect

This paper describes greatly enhanced version of the computer program SPECTRAN, which was initially presented in Paper No. 96-RA104.01, at the A&WMA 89th Annual Meeting in June 1996. The program has had three basic upgrades since that time. The first is provision of an option to use either batch-mode input from previously prepared data files or a {open_quotes}user-friendly{close_quotes} interactive input routine. The latter is primarily for first-time users and those having only one, or very few, spectra to process. The second improvement is the synthesis of 1/12 octave-band spectra from 1/3 octave-band spectra, with {open_quotes}tone correction,{close_quotes} in a manner similar to that used in the original version of the program. The third fundamental improvement is addition of a unique new capability to synthesize classic {open_quotes}critical-band{close_quotes} spectra from 1/3 octave-band input spectra. Critical-band spectra are also termed {open_quotes}equivalent-rectangular-bandwidth (ERB){close_quotes} and {open_quotes}equal-contribution-to-speech (ECS){close_quotes} spectra.

Effects of pressure and temperature on gate valve unwedging  

SciTech Connect

The stem thrust required to unwedge a gate valve is influenced by the pressure and temperature when the valve is closed and by the changes in these conditions between closure and opening. {open_quotes}Pressure locking{close_quotes} and {open_quotes}thermal binding{close_quotes} refer to situations where pressure and temperature effects cause the unwedging load to be much higher than normal. A model of these phenomena has been developed. Wedging (closure) is modeled as developing an {open_quotes}interference{close_quotes} between the disk and its seat rings in the valve. The effects of pressure and temperature are analyzed to determine the change in this disk-to-seat {open_quotes}interference{close_quotes}. Flexibilities, of the disk, body, stem and yoke strongly influence the unwedging thrust. Calculations and limited comparisons to data have been performed for a range of valve designs and scenarios. Pressure changes can increase the unwedging load when there is either a uniform pressure decrease, or a situation where the bonnet pressure exceeds the pressures in the adjacent piping. Temperature changes can increase the unwedging load when: (1) valve closure at elevated system temperature produces a delayed stem expansion, (2) a temperature increase after closure produces a bonnet pressure increase, or (3) a temperature change after closure produces an increase in the disk-to-seat {open_quotes}interference{close_quotes} or disk-to-seat friction.

Set theory and physics  

SciTech Connect

Inasmuch as physical theories are formalizable, set theory provides a framework for theoretical physics. Four speculations about the relevance of set theoretical modeling for physics are presented: the role of transcendental set theory (i) in chaos theory, (ii) for paradoxical decompositions of solid three-dimensional objects, (iii) in the theory of effective computability (Church-Turing thesis) related to the possible {open_quotes}solution of supertasks,{close_quotes} and (iv) for weak solutions. Several approaches to set theory and their advantages and disadvantages for physical applications are discussed: Cantorian {open_quotes}naive{close_quotes} (i.e., nonaxiomatic) set theory, contructivism, and operationalism. In the author`s opinion, an attitude, of {open_quotes}suspended attention{close_quotes} (a term borrowed from psychoanalysis) seems most promising for progress. Physical and set theoretical entities must be operationalized wherever possible. At the same time, physicists should be open to {open_quotes}bizarre{close_quotes} or {open_quotes}mindboggling{close_quotes} new formalisms, which need not be operationalizable or testable at the time of their creation, but which may successfully lead to novel fields of phenomenology and technology.

Use of sulfur hexafluoride and perfluorocarbon tracers in plutonium storage containers for leak detection  

SciTech Connect

This study involves an investigation of the feasibility of a tracer-based leak detection system for long-term interim plutonium storage. In particular, a protocol has been developed based on the use of inert tracers with varying concentrations in order to {open_quotes}fingerprint{close_quotes} or {open_quotes}tag{close_quotes} specific containers. A particular combination of tracers at specific ratios could be injected into the free volume of each container, allowing for the detection of leaks as well as determination of the location of leaking containers. Based on plutonium storage considerations, sulfur hexafluoride and four perfluorocarbon tracers were selected and should allow a wide range of viable fingerprinting combinations. A {open_quotes}high-low{close_quotes} protocol which uses two distinct chromatographic peak areas or concentration levels, is recommended. Combinations of air exchange rates, detection durations, and detectability limits are examined in order to predict minimum tracer concentrations required for injection in storage containers.

In particular the author considers hohlraums that are in what has become known as a {open_quotes}primary{close_quotes} {open_quotes}secondary{close_quotes} configuration, namely geometries in which the laser is absorbed in a primary region of a hohlraum, and only radiation energy is transported to a secondary part of the hohlraum that is shielded from seeing the laser light directly. Such hohlraums have been in use of late for doing LTE opacity experiments on a sample in the secondary and in recently proposed {open_quotes}shimmed{close_quotes} hohlraums that use gold disks on axis to block a capsule`s view of the cold laser entrance hole. The temperature/drive of the secondary, derived herein, scales somewhat differently than the drive in simple hohlraums.

The proof of the quality of these piping systems can be executed by means of fracture mechanics calculations by showing that in every case the leakage monitoring system already detect cracks which are clearly smaller than the critical crack. Thus the leak before break behavior and the break preclusion concept is implicitly affirmed. In order to further diminish conservativities in the fracture mechanics procedures, specific research projects are executed which are explained in this contribution.

We exploit this fact to develop an aggressive hybrid approach which attempts to compile a KB exactly until a given resource limit is reached, then falls back to approximate compilation into unit clauses. The resulting approach handles all of the critically constrained Random 3SAT KBs with average savings of an order of magnitude over the brute-force approach.

Classical methods for interpreting objective function minimization as intelligent inference  

SciTech Connect

Most recognition algorithms and neural networks can be formally viewed as seeking a minimum value of an appropriate objective function during either classification or learning phases. The goal of this paper is to argue that in order to show a recognition algorithm is making intelligent inferences, it is not sufficient to show that the recognition algorithm is computing (or trying to compute) the global minimum of some objective function. One must explicitly define a {open_quotes}relational system{close_quotes} for the recognition algorithm or neural network which identifies the: (i) sample space, (ii) the relevant sigmafield of events generated by the sample space, and (iii) the {open_quotes}relation{close_quotes} for that relational system. Only when such a {open_quotes}relational system{close_quotes} is properly defined, is it possible to formally establish the sense in which computing the global minimum of an objective function is an intelligent, inference.

Specification and acceptance in nondestructive testing  

SciTech Connect

Nondestructive testing is often defined as the detection of defects in materials by using techniques that do not damage the product tested. For the user, a supply without defects is a reliable one, i.e., able to perform a required function under stated conditions for a stated period of time. For the quality manager, a supply without defects is one complying with specifications. This is why the vocabulary of quality control has opted for the following definition: [open quotes]Defect: the nonfulfillment of specified requirements for a characteristic of an item[close quotes]. In this case too, the author has to define the state of a characteristic and shall prefer to employ the word [open quotes]nonconformity[close quotes]. The specifier cannot only consider supplies in their totality, but must also look for the reasons for any failures. The performance of a supply may be reduced by the presence of variations in the physical, chemical, or structural properties of the material. Finally, the nondestructive testing inspector measures the variations of a physical quantity that are related to the presence of discontinuities. After completing the supply inspection and according to the type of data processing, the NDT inspector in fact measures the peak height on a diagram or the spotted area on an image. The defect is thus, as for the specifier, an item and shall employ the word [open quotes]signal[close quotes]. It is clear that, in the definition of NDT given at the beginning, the word [open quotes]defect[close quotes] must be taken in the sense of [open quotes]discontinuity[close quotes]. This is why the author shall prefer to define NDT as the verification of the homogeneity of a supply without its being damaged; by [open quotes]homogeneity[close quotes] it is meant that there is no significant difference with respect to samples taken from the supply.

Toxicity evaluation and hazard review for Rigid Foam  

SciTech Connect

Rigid Foam is a chemical delay foam used to completely encapsulate an object or to block access to an area. Prior studies have indicated that the final foam product is essentially non-toxic. The purpose of this study was to evaluate and summarize the current chemical and toxicological data available on the components of Rigid Foam and to update the information available on the toxicity of the final Rigid Foam product. Since the possibility exists for a partial deployment of Rigid Foam where only one of the components is released, this study also examined the toxicity of its chemical constituents. Rigid Foam is composed of an {open_quotes}A{close_quotes} and {open_quotes}B{close_quotes} Component. The {open_quotes}A{close_quotes} component is primarily a polymeric isocyanate and the {open_quotes}B{close_quotes} component is a mixture of polyols. In addition to the primary constituents, dichlorodifluoromethane and trichlorofluoromethane are present as blowing agents along with catalysts and silicone surfactants necessary for foaming. The pre-deployed {open_quotes}A{close_quotes} and {open_quotes}B{close_quotes} components are stored in separate vessels and are brought together in static mixing nozzles for dispersal. The results of this evaluation indicate that a completely deployed Rigid Foam under normal conditions is essentially non-toxic as determined previously. However, in the event of a partial deployment or deployment of an individual component directly at an unprotected individual, the degree of hazard is increased due to the toxic and corrosive nature of the individual constituents. The health hazard would depend on the properties of the material to which the person was exposed.

Unit meets coal`s challenges: Florida project sets environmental marks while it scores a number of management points as well  

SciTech Connect

Bringing in the cleanest-burning conventional coal-fired generating unit in the country in 39 months isn`t good enough for managers on a Florida project. They are making it a model of construction partnering and safety as well. The process has contained costs on the second unit at Orlando utilities Commission`s Stanton Energy Center. The new unit will match the 460-Mw capacity of the upgraded 1987 unit. But Timothy D. Slepow, OUC`s project coordinator, says the current budget has been cut from $522 million to $480 million. Unit 1 cost $516 million. {open_quotes}This is not a duplicate of unit 1,{close_quotes} says Hal E. Smith, executive partner of Black & Veatch, Kansas City, Mo., designer and construction manager. {open_quotes}In the permitting process, there was a tremendous effort to ratchet down to now-established best available control technology.{close_quotes} Unit 1, also designed by B&V, is operating at far below permitted emission levels, says Gregory A. DeMuth, OUC`s environmental director. Sulfur dioxide discharges are less than one-quarter of what permits allow, while emissions of nitrogen oxides and particulates also are considerably below requirements. Because of that operating record, the utility tried to get a {open_quotes}bubble{close_quotes} permitting concept applied to unit 2, DeMuth says. But state and federal environmental agencies {open_quotes}said unit 2 had to stand alone,{close_quotes} and pressed for even stiffer controls, he says. The major change is a selective catalytic reduction system that injects ammonia to slash nitrogen oxides emissions. {open_quotes}This will be the first coal-fired unit in the U.S. to have full volume SCR,{close_quotes} says Smith. {open_quotes}It`s previously been seen only on gas turbines.

Programmed cell death for defense against anomaly and tumor formation  

SciTech Connect

Cell death after exposure to low-level radiation is often considered evidence that radiation is poisonous, however small the dose. Evidence has been accumulating to support the notion that cell death after low-level exposure to radiation results from activation of suicidal genes {open_quote}programmed cell death{close_quote} or {open_quote}apoptosis{close_quote} - for the health of the whole body. This paper gives experimental evidence that embryos of fruit flies and mouse fetuses have potent defense mechanisms against teratogenic or tumorigenic injury caused by radiation and carcinogens, which function through programmed cell death.

Evaluation of the thermodynamic performance of pulse tubes  

SciTech Connect

The thermodynamic performance of pulse tubes (PT) has been studied with emphasis on second law efficiencies and volume effects. The various pulse tube data of operation are compared to small Stirling coolers, characterized by a parameter set similar to the PT specifications. A modified {open_quotes}thermal shunt{close_quotes} model (modified {open_quotes}Bejan model{close_quotes}) is utilized for the comparison. The model predicts a small refrigeration load asymptote of the efficiency proportional to the load itself in partial agreement with pulse tube data.

Mixed constraint satisfaction: A framework for decision problems under incomplete knowledge

Constraint satisfaction is a powerful tool for representing and solving decision problems with complete knowledge about the world. We extend the CSP framework so as to represent decision problems under incomplete knowledge. The basis of the extension consists in a distinction between controllable and uncontrollable variables - hence the terminology {open_quotes}mixed CSP{close_quotes} - and a {open_quotes}solution{close_quotes} gives actually a conditional decision. We study the complexity of deciding the consistency of a mixed CSP. As the problem is generally intractable, we propose an algorithm for finding an approximate solution.

Innovative rates: Using market forces to become more competitive and achieve DSM goals  

SciTech Connect

Electric and gas utilities are perhaps the last remaining industries to describe their charges to customers as {open_quotes}rates{close_quotes} rather than {open_quotes}prices.{close_quotes} Tellingly, their customers are more often known as {open_quotes}ratepayers.{close_quotes} As competition becomes a reality, the successful utilities will be those companies who change quickly, not just to respond to their customers` needs, but also to take advantage of market economics. For this is becoming a brave new world where profits will be determined by efficiency and service rather than regulatory fiat. Innovative rates - {open_quotes}creative pricing{close_quotes} in most industries - have tremendous power to help utilities become more competitive by improving efficiency. Successful utilities will use these rates to sell more kilowatthours per kilowatt of generating capacity, spend less on fuel per kilowatthour generated, even reduce employee costs per customer. Studies of time-of-use, interruptible, curtailable, and real-time utility prices have shown consistent and reliable benefits, resting on a foundation of market economics going back to the 18th century. This paper reviews a few of those studies, focusing on the simplest type of innovative rate - time-of-use - with the greatest potential impact. It also reviews how market forces, and the resulting effect on pricing, led to an efficiency increase of 30% for U.S. airlines in only a decade. Similarly dramatic effects can be expected for gas and electric utilities.

Biomorphic robots as a persistent means for removing explosive mines  

SciTech Connect

The current variety and dispersion of explosive mines is a daunting technological problem for current sensory techniques. The bottom line is that the only way to insure a mine has been found and removed is to step on it. As this is an upsetting proposition for biological organisms like animals or children, this paper details a proposed non-biological method that may have validity following additional research into the new science of Biomorphic Machines. A Robobiologist at LANL has invented and developed a variety of {open_quotes}living{close_quotes} robots that are solar powered, legged, autonomous, adaptive to massive damage and terrain, and very inexpensive. This technology, called Nervous Net (Nv) design, allows for the creation of capable walking mechanisms (known as {open_quotes}Biomorphic Robots{close_quotes}) which rather than run on a {open_quotes}work{close_quotes} ethic, use {open_quotes}survivalist{close_quotes} design principles. These principles allow Nv based machines to continue doing work even after multiple limbs have been removed or damaged, and to dynamically negotiate complex terrains as an emergent property of their operation. They are not programmed, and indeed, the 12 transistor controller used keeps their electronic cost well below that of most pocket radios. It is suspected that in finding and removing randomly placed explosive mines, they may be an interesting, capable solution.

Electronic-structure investigation of oxidized aluminum films with electron-momentum spectroscopy  

SciTech Connect

Electron-momentum spectroscopy (EMS) or ({ital e},2{ital e}) measurements with oxidized aluminum thin films have been performed. Due to the surface sensitive nature of the EMS spectrometer employed, the measured ({ital e},2{ital e}) events come from the front oxidized layer as viewed by the electron detectors. The measurements show clearly two major features in the spectral momentum density distribution and they are related to the upper valence band and the lower valence band of aluminum oxide. The first is a {open_quote}{open_quote}dual parabola{close_quote}{close_quote} energy-momentum dispersion pattern spanning about 8 eV in the upper valence band. This dual parabola pattern has been qualitatively reproduced by a linear muffin-tin orbital (LMTO) calculation on spherically averaged {alpha}-Al{sub 2}O{sub 3} with nearly the same energy span. In the lower valence band, the LMTO calculation indicates a dispersion spanning about 5 eV, and the measured spectral momentum density plot shows a similar {open_quote}{open_quote}bowl{close_quote}{close_quote} shape but with less dispersion. The possible causes that blur the dispersion in the lower valence band are discussed. Other features in the spectral momentum density distribution are also discussed and compared with the LMTO calculation. {copyright} {ital 1996 The American Physical Society.}

The scope of the Weatherization Assistance Program: Profile of the population in need  

SciTech Connect

The U.S. Department of Energy (DOE) is conducting a national evaluation of its Weatherization Assistance Program, an energy efficiency program that provides financial assistance to qualifying low-income households for the {open_quotes}weatherization{close_quotes} of their housing units. The evaluation, being conducted for the Department by Oak Ridge National Laboratory (ORNL), is comprised of five studies. One of the five is a two-part analysis of the scope of the Weatherization Assistance Program and other resources devoted to low-income energy efficiency, including the number of dwellings weatherized to date and the population remaining to be served. This study is referred to here as the {open_quotes}Scope{close_quotes} study. This report presents the results of the second part of the {open_quotes}Scope{close_quotes} study, which investigates the characteristics of the population eligible for and in need of the DOE Weatherization Assistance Program - The Profile of the Population in Need. The {open_quotes}Profile{close_quotes} study is an attempt to use the Energy Information Administration`s Residential Energy Consumption Survey (RECS) for 1990 to define the weatherization-related characteristics of the low-income population. The RECS, a national survey with a sample size of 5,095 households, is the most reliable source for information regarding residential energy-use and housing characteristics because data is collected from fuel vendors on actual household energy bills and consumption for a large and representative sample of households.

Introduction to efficient lighting for retail environments

A quantitative method for measuring the quality of history matches  

SciTech Connect

History matching can be an efficient tool for reservoir characterization. A {open_quotes}good{close_quotes} history matching job can generate reliable reservoir parameters. However, reservoir engineers are often frustrated when they try to select a {open_quotes}better{close_quotes} match from a series of history matching runs. Without a quantitative measurement, it is always difficult to tell the difference between a {open_quotes}good{close_quotes} and a {open_quotes}better{close_quotes} matches. For this reason, we need a quantitative method for testing the quality of matches. This paper presents a method for such a purpose. The method uses three statistical indices to (1) test shape conformity, (2) examine bias errors, and (3) measure magnitude of deviation. The shape conformity test insures that the shape of a simulated curve matches that of a historical curve. Examining bias errors assures that model reservoir parameters have been calibrated to that of a real reservoir. Measuring the magnitude of deviation assures that the difference between the model and the real reservoir parameters is minimized. The method was first tested on a hypothetical model and then applied to published field studies. The results showed that the method can efficiently measure the quality of matches. It also showed that the method can serve as a diagnostic tool for calibrating reservoir parameters during history matching.

Derivative expansions of renormaliztion group effective potentials for {phi}{sup 4} field theories  

SciTech Connect

We approximate an exact Renormalization Group (RG) equation for the flow of the effective action of {phi}{sup 4} field theories by including next-to-leading order (NLO) terms in a derivative expansion. This level of approximation allows us to treat effects of wavefunction renormalization which are beyond the scope of the leading order (LO) formulation. We compare calculations based on a {open_quote}latticized {close_quotes} version of our RG equation in 3 Euclidean dimensions directly with Monte Carlo (MC) results and find excellent overall agreement as well as substantial improvement over LO calculations. We solve the continuum form of our equation to find the Wilson fixed point and determine the critical exponent {eta} (0.046). We also find the critical exponents {nu} (0.666) and {omega} (0.735). These latter two are in much improved agreement with {open_quote}world`s best{close_quotes} values com- pared to those obtained at LO (where no prediction for {eta} is possible). We also find that the {open_quote}universal potential{close_quote} determined via MC methods by Tsypin can be understood quantitatively using our NLO RG equations. Careful analysis shows that ambiguities which plague {open_quote}smooth cutoff{close_quotes} formulations do not arise with our RG equations.

Sweden and the growing energy market  

SciTech Connect

Considerable changes have taken place within the Swedish energy system in recent years. Biofuels, for example, are steadily capturing greater market share. The most dramatic changes in biofuels have occurred in the district heating sector. Processed or upgraded fuels such as briquettes and pellets have become increasingly attractive heating alternatives in the single-family house sector. This development has come about largely as a result of Sweden`s long-term national energy policy, which states that the Swedish energy system, as far as possible, must be based on domestic and renewable energy sources with a minimum of detrimental impact on environment. Today`s basic and overall strategy seeks to utilize the pricing system of the competitive market to realize this program and to allocate energy resources. One consequence of this mode of thinking is the internalization of environmental costs in the pricing system. Another consequence is the Swedish electricity market reform that came into force this year. Many companies are now using the {open_quotes}greenness{close_quotes} of their products as a sales argument in their marketing. In the new competitive market, much attention has come to rest on the concept of {open_quotes}green energy{close_quotes} in general and on {open_quotes}green electricity{close_quotes} in particular. In a {open_quotes}bottom-to-top{close_quotes} perspective the behavior and preferences of consumers will be of considerable importance to energy supply companies.

Uncertainties in risk assessment at USDOE facilities  

SciTech Connect

The United States Department of Energy (USDOE) has embarked on an ambitious program to remediate environmental contamination at its facilities. Decisions concerning cleanup goals, choices among cleanup technologies, and funding prioritization should be largely risk-based. Risk assessments will be used more extensively by the USDOE in the future. USDOE needs to develop and refine risk assessment methods and fund research to reduce major sources of uncertainty in risk assessments at USDOE facilities. The terms{open_quote} risk assessment{close_quote} and{open_quote} risk management{close_quote} are frequently confused. The National Research Council (1983) and the United States Environmental Protection Agency (USEPA, 1991a) described risk assessment as a scientific process that contributes to risk management. Risk assessment is the process of collecting, analyzing and integrating data and information to identify hazards, assess exposures and dose responses, and characterize risks. Risk characterization must include a clear presentation of {open_quotes}... the most significant data and uncertainties...{close_quotes} in an assessment. Significant data and uncertainties are {open_quotes}...those that define and explain the main risk conclusions{close_quotes}. Risk management integrates risk assessment information with other considerations, such as risk perceptions, socioeconomic and political factors, and statutes, to make and justify decisions. Risk assessments, as scientific processes, should be made independently of the other aspects of risk management (USEPA, 1991a), but current methods for assessing health risks are based on conservative regulatory principles, causing unnecessary public concern and misallocation of funds for remediation.

Oxidation of o-xylene to phthalic anhydride over V{sub 2}O{sub 5}/TiO{sub 2} catalysts. Part 4. Mathematical modelling study and analysis of the reaction network

Results previously obtained for the oxidation of o-xylene and o-tolualdehyde over a 1% V{sub 2}O{sub 5}/TiO{sub 2} catalyst have been subjected to mathematical modelling, using comprehensive {open_quotes}rake{close_quotes} networks which incorporate adsorbed intermediates, a variety of routes to CO{sub 2}, and provision for the formation and removal from the surface of a {open_quotes}residue{close_quotes} formed at low conversion by both reactant conversion are presented; these contain series of parameters that are complex functions of the rate constants for the individual steps, their values being obtained by regression analysis. The modelling confirms that phthalic anhydride is formed through a sequential process involving adsorbed forms of o-tolualdehyde and phthalide as intermediates, but it is not formed by direct conversion of o-xylene and o-tolualdehyde. At high conversion, phthalic anhydride selectivity generally passes through a maximum, showing that it can undergo further oxidation to CO{sub 2}. The selectivity for the {open_quotes}residue{close_quotes} (S{sub R}) also passes through a maximum as it is removed from the surface; moreover, the initial slopes of S{sub r} vs conversion curves show that the {open_quotes}residue{close_quotes} is formed early in the reaction network. 30 refs., 2 figs., 2 tabs.

Unitarized pseudoscalar meson scattering amplitudes from three flavor linear sigma models  

SciTech Connect

The three flavor linear sigma model is studied as a {open_quotes}toy model{close_quotes} for understanding the role of possible light scalar mesons in the {pi}{pi}, {pi}K and {pi}{eta} scattering channels. The approach involves computing the tree level partial wave amplitude for each channel and unitarizing by a simple K-matrix prescription which does not introduce any new parameters. If the renormalizable version of the model is used there is only one free parameter. While this highly constrained version has the right general structure to explain {pi}{pi} scattering, it is {open_quotes}not quite{close_quotes} right. A reasonable fit can be made if the renormalizability (for the effective Lagrangian) is relaxed while chiral symmetry is maintained. The occurrence of a Ramsauer-Townsend mechanism for the f{sub 0}(980) region naturally emerges. The effect of unitarization is very important and leads to {open_quotes}physical{close_quotes} masses for the scalar nonet all less than about 1 GeV. The a{sub 0}(1450) and K{sub 0}{sup *}(1430) appear to be {open_quotes}outsiders{close_quotes} in this picture and to require additional fields. Comparison is made with a scattering treatment using a more general nonlinear sigma model approach. In addition some speculative remarks and a highly simplified larger toy model are devoted to the question of the quark substructure of the light scalar mesons.

Low cost power augmentation by water injection on dual fuel gas turbines  

SciTech Connect

It is {open_quotes}common knowledge{close_quotes} that the power output of a combustion turbine (gas turbine) can be increased by as much as ten percent above the {open_quotes}dry{close_quotes} output by injecting water into the combustion zone. This enhancement is particularly useful during periods of high inlet air temperature when the turbine output is lowered due to the reduced air flow of the lower density hot air. The additional mass flow of water will partially offset the reduction of air mass flow. The specific heat of the water vapor (roughly twice that of air) allows increased fuel (and output) at approximately twice the rate of that which would result if the air mass flow were increased by a lower inlet air temperature. It is often a big step from {open_quotes}common knowledge{close_quotes} to actual practice and that step is the subject of this paper. In the summer of 1994 the Lincoln Electric System (L.E.S.), a public utility serving Lincoln, Nebraska ran operational tests on their 1974 G.E. MS-7001B gas turbine with water injection on natural gas fuel. The results proved the {open_quotes}common knowledge{close_quotes} in that the {open_quotes}wet{close_quotes} power was increased by approximately 9% above the {open_quotes}dry{close_quotes} power when the water/fuel mass flow ratio was held to a fairly conservative 1.2/1.0. Further testing, in August of 1995, confirmed these results. Test set for October, 1995, will check the injection system while operating on oil fuel. In this case, the water injection is intended as a NOx reduction measure only with the water/fuel ratio being held to a maximum of 0.5/1.0. The {open_quotes}wet{close_quotes} power is expected to increase by 4%. The utility is also planning tests on a similar system being installed on a Westinghouse model 251 gas turbine.

Walter Slocombe explained that {open_quotes}[t]he dominant problem of U.S. nuclear strategy is credibly using U.S. nuclear power to deter and if necessary resist nonnuclear as well as nuclear threats to America`s allies, forces, and interests overseas.{close_quotes} As a result, the {open_quotes}flexible response{close_quotes} doctrine was developed to declare {open_quotes}that the United States, in consultation with its allies, is prepared to use nuclear weapons should other means of protection from Soviet attack threaten to fail.{close_quotes} In contrast, Freeman Dyson pointed out the Soviet Union was committed to the concept of {open_quotes}counterforce,{close_quotes} which meant that {open_quotes}if the Soviet Union sees a nuclear attack coming or has reason to believe that an attack is about to be launched, the Soviet Union will strike first at the attacker`s weapons with all available forces, and will then do whatever is necessary in order to survive.{close_quotes} Out of these military postures a tense peace ironically emerged, but the terms by which decisions were made about controlling weapons of mass destruction (i.e., nuclear, chemical, and biological weapons) were the terms of war. The thesis of this paper is that the end of the Cold War marks a shift away from reliance on military might toward an international commitment to control weapons of mass destruction through the `rule of law.`

Production and measurement of minor actinides in the commercial fuel cycle  

SciTech Connect

The minor actinide elements, particularly neptunium and americium, are produced as a normal byproduct of the operation of thermal power reactors. Because of the existence of long-lived isotopes of these elements, they constitute the major sources of the residual radiation in spent fuel or in wastes resulting from reprocessing. This has led to examinations by some countries of the possibility of separating the minor actinides from waste products. The papers found in this report address the production of minor actinides in common thermal power reactors as well as approaches to measure these materials in various media. The first paper in this volume, {open_quotes}Production of Minor Actinides in the Commercial Fuel Cycle,{close_quotes} uses calculations with the ORIGEN2 reactor and decay code to estimate the amounts of minor actinides in spent fuel and separated plutonium as a function of reactor irradiation and the time after discharge. The second paper, {open_quotes}Destructive Assay of Minor Actinides,{close_quotes} describes a number of promising approaches for the chemical analysis of minor actinides in the various forms in which they are found at reprocessing plants. The next paper, {open_quotes}Hybrid KED/XRF Measurement of Minor Actinides in Reprocessing Plants,{close_quotes} uses the results of a simulation model to examine the possible applications of the hybrid KED/XRF instrument to the determination of minor actinides in some of the solutions found in reprocessing plants. In {open_quotes}Calorimetric Assay of Minor Actinides,{close_quotes} the authors show some possible extensions of this powerful technique beyond the normal plutonium assays to include the minor actinides. Finally, the last paper in this volume, {open_quotes}Environment Measurements of Transuranic Nuclides,{close_quotes} discusses what is known about the levels of the minor actinides in the environment and ways to analyze for these materials in environmental matrices.

A prediction investigated: Antrim gas fields in central and southern Michigan  

SciTech Connect

An exploration rationale based on observations in the Appalachian basin has been applied to Michigan. The rationale assumes that not all shale gas is indigenous and that gas production is related to both a greater gas content and a greater fracture density than regional average. Areas [open quotes]charged with gas[close quotes] can be expected where methane has migrated from downdip Antrim or from older sources into stratigraphic traps created by shale facies change. Increased fracturing requires geologically [open quotes]new[close quotes] crustal movement. Small areas of predicted shale gas potential were identified using (1) mapped facies changes, (2) bitumen concentrations, (3) Traverse Lime structure, and (4) glacial hinge lines. Three areas, about 6 by 15 mi, in south central Michigan showed an organic matter (bitumen) equal to or greater than in Otsego County. Each area was crossed by a shale to shale facies change with less permeable shale positioned updip of expected gas movement. All three areas lie along projections of glacial hinge lines, where geologically [open quotes]new[close quotes] flexing ([approximately]13,000 YBP) is postulated to have created [open quotes]fresh[close quotes], localized breakage. The areas were superimposed on an oil and gas map and well records in and around the areas were searched for evidence of gas, water, or lost circulation. Antrim [open quotes]gas[close quotes] occurred in two areas; specifically, seven wells in or near the southern, shallowest area and in four wells in or bordering another. Although the evidence is inconclusive, the gas reported where gas was predicted is presented as support for the exploration methodology advanced.

The influence of environmental conditions on tree-ring series of Norway spruce for different canopy and vitality classes  

SciTech Connect

A dendroecological study of Norway spruce trees was undertaken as part of an interdisciplinary project investigated the influence of air pollution on tree growth in northern Germany. They analyzed individual trees stratified according to three different canopy classes and three different vitality classes, using response function analysis. There is a significant positive correlation between precipitation during the growing season and the tree-ring series, and that the observed forest decline is probably caused by a severe unknown stress factor (but clearly not a climate factor) during the mid-1950s. In this article a model is applied for simultaneous adjustment of trend and explanatory variables for tree-ring chronologies. After analyzing the tree-ring chronologies of the Norway spruce by these more sophisticated methods, it is found that: (1) the stockastic response functions for precipitation during the growing season are principally constant over time and positive, (2) the stochastic response functions for the temperature in February and March are not constant and become significant after the mid-1950s for trees from the classes {open_quotes}not dominant-vital,{close_quotes} {open_quotes}not dominant-moderately vital,{close_quotes}{open_quotes}dominant-not vital,{close_quotes} {open_quotes}moderately dominant-not vital,{close_quotes} and {open_quotes}not dominant-not vital,{close_quotes} (3) the influence of climate factors on tree-ring development is higher if the vitality and dominance of the trees is lower, (4) addition of an SO{sub 2} emission curve as explanatory variable, simultaneously with trend and climate variables for tree-ring chronologies, did not reveal a significant air pollution effect on tree-ring development. 37 refs., 8 figs., 1 tab.

Art form as an object of cognitive modeling (towards development of Vygotsky`s semiotic model)  

SciTech Connect

We suggest a further development of Vygotsky`s esthetic-semiotic model. First, we discuss Vygotsky`s model originally developed for the analysis of Ivan Bunin`s story {open_quotes}Light Breath{close_quotes}. Vygotsky analyzes formal methods used by Bunin to achieve a specific esthetic effect of {open_quote}lightness{close_quotes} while describing {open_quotes}dirty{close_quotes} events of everyday life. According to Vygotsky, this effect is achieved by ordering of events in a non-linear fashion. Vygotsky creams an airy pattern of smooth lines connecting events of story that he first orders linearly in time. And, he insists that this airy pattern creates an impression of airy lightness. In the language of semiotics, the esthetic effect is created by a specific structural organization of signs. Second, we present our critique of Vygotsky`s model. Although, we do not agree with Vygotsky`s sometimes moralistic judgements, and we consider the dynamics between inner personal values and received moral values to be more complicated than implied in his judgements, our critique in this paper is limited to the structure of his semiotic model. We emphasize that Vygotsky`s model does not explicitly account for a hierarchy of multiple levels of semiotic analysis. His analysis regularly slips from one level to another: (1) a lever of cognitive perception by a regular reader is confused with a level of creative genius of a writer; (2) {open_quotes}open{close_quotes} time of real world is mixed up with {open_quote}closed{close_quote} time of the story; (3) events are not organized by the hierarchy of their importance, nor in real world, nor in the inner model of the personages, nor in the story.

A perspective on safeguarding and monitoring of excess military plutonium  

SciTech Connect

The purpose of this paper is to provide a perspective and framework for the development of safeguarding and monitoring procedures for the various stages of disposition of excess military plutonium. The paper briefly outlines and comments on some of the issues involved in safeguarding and monitoring excess military plutonium as it progresses from weapons through dismantlement, to fabrication as reactor fuel, to use in a reactor, and finally to storage and disposal as spent fuel. {open_quotes}Military{close_quotes} refers to ownership, and includes both reactor-grade and weapon-grade plutonium. {open_quotes}Excess{close_quotes} refers to plutonium (in any form) that a government decides is no longer needed for military use and can be irrevocably removed from military stockpiles. Many of the issues and proposals presented in this paper are based on, or are similar to, those mentioned in the National Academy of Sciences (NAS) report on excess military plutonium. Safeguards for plutonium disposition are discussed elsewhere in terms of requirements established by the U.S. Department of Energy (DOE), the U.S. Nuclear Regulatory Commission (NRC), and the International Atomic Energy Agency (IAEA). Here, the discussion is less specific. The term {open_quotes}safeguarding{close_quotes} is used broadly to refer to materials control and accountancy (MC&A), containment and surveillance (C&S), and physical protection of nuclear materials by the state that possesses those materials. This is also referred to as material protection, control, and accountancy (MPCA). The term {open_quotes}safeguarding{close_quotes} was chosen for brevity and to distinguish MPCA considered in this paper from international or IAEA safeguards. {open_quotes}Monitoring{close_quotes} is used to refer to activities designed to assure another party (state or international organization) that the nuclear materials of the host state (the United States or Russia) are secure and not subject to unauthorized use.

Improved characterization of reservoir behavior by integration of reservoir performances data and rock type distributions  

SciTech Connect

An integrated geological/petrophysical and reservoir engineering study was performed for a large, mature waterflood project (>250 wells, {approximately}80% water cut) at the North Robertson (Clear Fork) Unit, Gaines County, Texas. The primary goal of the study was to develop an integrated reservoir description for {open_quotes}targeted{close_quotes} (economic) 10-acre (4-hectare) infill drilling and future recovery operations in a low permeability, carbonate (dolomite) reservoir. Integration of the results from geological/petrophysical studies and reservoir performance analyses provide a rapid and effective method for developing a comprehensive reservoir description. This reservoir description can be used for reservoir flow simulation, performance prediction, infill targeting, waterflood management, and for optimizing well developments (patterns, completions, and stimulations). The following analyses were performed as part of this study: (1) Geological/petrophysical analyses: (core and well log data) - {open_quotes}Rock typing{close_quotes} based on qualitative and quantitative visualization of pore-scale features. Reservoir layering based on {open_quotes}rock typing {close_quotes} and hydraulic flow units. Development of a {open_quotes}core-log{close_quotes} model to estimate permeability using porosity and other properties derived from well logs. The core-log model is based on {open_quotes}rock types.{close_quotes} (2) Engineering analyses: (production and injection history, well tests) Material balance decline type curve analyses to estimate total reservoir volume, formation flow characteristics (flow capacity, skin factor, and fracture half-length), and indications of well/boundary interference. Estimated ultimate recovery analyses to yield movable oil (or injectable water) volumes, as well as indications of well and boundary interference.

How hot is it? (A comparison of advanced technology temperature logging systems)  

SciTech Connect

Temperature is a basic input for many branches of geology and geophysics, but obtaining detailed, precise temperature logs has faced problems in cost, reliability and limiting temperatures. Field tests were conducted in the summer of 1995 on four {open_quotes}state of the art{close_quotes} temperature logging systems. Over a one month period each of the systems were used to log a 1050 meter deep hole. In addition, two of the tools were used to log a geothermal exploration well in Nevada to extend the temperature range of the tests. The four systems used are of three major types and cover the range of currently available technology. They are; (1) a conventional {open_quotes}electric-line{close_quotes} system, (2) two separate pressure and temperature sensing {open_quotes}memory tool{close_quotes} computer systems, and (3) a Distributed optical fibre Temperature Sensing (DTS) system. The tools produced temperature versus depth and temperature gradient versus depth logs that were coincident within the {open_quotes}noise{close_quotes} level. The multiple independent logs demonstrate that most of the {open_quotes}noise{close_quotes} seen in gradient logs is due to convection cells in the borehole and to meter scale lithology changes outside the hole. Internal system noise was shown to be relatively small. The computer and electric-line tools have about an order of magnitude better precision and resolution than the DTS, but the DTS has the advantage of being able to measure temperature instantaneously throughout the hole, and would be well suited for monitoring dynamic systems. These systems had various strong points, but all provided accurate, detailed, cost effective measurements in the field.

Relationship between dopamine transporter occupancy and methylphenidate induced high in humans  

SciTech Connect

The inhibition of the dopamine transporter (DAT) by cocaine has been shown to be indispensable for its reinforcing properties. The development of drugs that inibit the DAT has become a major target to prevent cocaine`s effects. However prevention of the {open_quotes}high{close_quotes} by DAT inhibitors has never been demonstrated. This study evaluates the ability to block methylphenidate (MP), a DAT inhibitor drug with similar reinforcing properties to cocaine, induced {open_quotes}high{close_quotes} by prior DAT inhibition. It uses PET and [{sup 11}C]d-threo-methylphenidate to measure the relationship between DAT occupancy prior to administration of MP and the intensity of the subjective perception of the {open_quotes}high{close_quotes} in 8 controls. MP (0.375 mg/kg iv) which was administered as a single injection and also as two sequential doses given 60 minutes apart significantly reduced the ratio of the distribution volume for [{sup 11}C]d-threo-methylphenidate in striatum to that in cerebellum from a baseline of 2.83 {plus_minus} 0.2 to 1.29 {plus_minus} 0.1 at 7 minutes and to 1.37 {plus_minus} 0.2 at 60 minutes after a single injection of MP and to 1.14 {plus_minus} 0.1 at 7 minutes after the second of two sequential MP doses. This corresponds to a DAT occupancy by MP of 84% {plus_minus} 7 at 7 minutes and of 77% {plus_minus} 6 at 60 minutes after a single injection of MP and of 93% {plus_minus} 7 at 7 after the second of two sequential MP doses. The subjective perception of {open_quotes}high{close_quotes} experienced after the second injection of MP was of a similar magnitude to that experienced after the first injection of MP was of a similar magnitude to that experienced after the first injection, in spite of the very different starting DAT occupancies (0 and 77%, respectively). DAT occupancy was not correlated with the {open_quotes}high{close_quotes}; and one subject with 100% DAT occupancy did not perceive the {open_quotes}high{close_quotes}.

Antiferromagnetic hedgehogs with superconducting cores  

SciTech Connect

Excitations of the antiferromagnetic state that resemble antiferromagnetic hedgehogs at large distances but are predominantly superconducting inside a core region are discussed within the context of Zhang{close_quote}s SO(5)-symmetry-based approach to the physics of high-temperature superconducting materials. Nonsingular, in contrast with their hedgehog cousins in pure antiferromagnetism, these texture excitations are what hedgehogs become when the antiferromagnetic order parameter is permitted to {open_quotes}escape{close_quotes} into superconducting directions. The structure of such excitations is determined in a simple setting, and a number of their experimental implications are examined. {copyright} {ital 1998} {ital The American Physical Society}

Context for the cultural impact of the computer  

SciTech Connect

It is apparent that the computer has had and is having a profound effect on everyone`s life. However, it is not always apparent what these effects are, where they originate, what direction they are taking us, or what controls them. Unfortunately, discussions concerning these issues often lack needed context -- terminology and ideas that help one uncover the underlying reality. This paper attempts to provide some of that context by introducing Jacques Ellul`s concept of {open_quotes}technique{close_quotes} -- encompassing much more than the computer. Many of these ideas grew out of {open_quotes}The Cultural Impact of the Computer{close_quotes}, a senior-level course taught by the author at Baylor University. The need for such context became evident when preparing for that course.

This report will place attention on the strategy and implementation of a multiagency inspection program in Sonoma County, California. This is a new effort coordinated by City, County and State agencies to publicly recognize auto repair facilities that demonstrate compliance with multi-media regulations for air quality, wastewater and hazardous waste. Historically the {open_quotes}command-and-control{close_quotes} environmental enforcement scheme has created adversarial relationships and pitted the regulatory agencies against business in a battle of notices of violations, fines and litigation. Furthermore, regulators have traditionally overlooked the power of the public to assist business with compliance to environmental regulations.

Density functional calculations have been performed for many isomers of carbon clusters C{sub n} (14{le}n{le}24 , n even) using both local spin density and gradient-corrected approximations to the exchange-correlation energy. The stable isomers include chains, rings, graphitic ({open_quotes}plate{close_quotes} and {open_quotes}bowl{close_quotes}), and cagelike structures, and we observe a fourfold periodicity in several structural classes, not only the monocyclic rings. Stable cages exist for all clusters, and double rings are less stable than the monocyclic rings. Gradient corrections are significant, but quite regular within a given structural type. The bonding trends found should also apply to larger clusters. {copyright} {ital 1997} {ital The American Physical Society}

The IEC thruster employs a spherical configuration, wherein ions are generated and accelerated towards the center of a spherical vacuum chamber. Virtual cathode formation in a high-density central core region, combined with a locally distorted cathode grid potential field, extracts accelerated ions in an intense quasi-neutral ion jet. Other than the jet formation, the IEC thruster is quite analogous to a planar electrostatic ion thruster {open_quote}{open_quote}folded{close_quote}{close_quote} into spherical form.

Two longer runs completed the data base required for kinetic characterization of the unpromoted {open_quotes}zinc chromite{close_quotes} catalyst. Although analysis of the data is not complete, it is evident that: (1) stirrer speed has no significant effect on the measured reaction rate, and; (2) carbon dioxide appears to inhibit catalyst activity.

The role of strategic environmental data management in emissions tracking and compliance assurance  

SciTech Connect

An effective environmental data management (FDM) system can be one of the most important tools for an industrial facility to assure and demonstrate compliance with environmental regulations. There are both {open_quotes}Environmental{close_quotes} requirements as well as {open_quotes}Information Technology{close_quotes} needs that should be addressed prior to the selection of an EDM system. Environmental managers` and engineers` biggest challenges today are in improving analytical capabilities through improved data management. Environmental Systems Integration (ESI) refers to the marriage of a comprehensive EDM tool with existing systems within an enterprise to optimize the task of emissions tracking, recordkeeping, reporting and compliance. ESI invariably calls for an ability to customize the EDM system to user-specific needs including effective utilization of existing information and resources.

Output power characteristics and performance of TOPAZ II Thermionic Fuel Element No. 24  

SciTech Connect

A final report on the output power characteristics and capabilities of single cell TOPAZ II Thermionic Fuel Element (TFE) No. 24 is presented. Thermal power tests were conducted for over 3000 hours to investigate converter performance under normal and adverse operating conditions. Experiments conducted include low power testing, high power testing, air introduction to the interelectrode gap, collector temperature optimization, thermal modeling, and output power characteristic measurements. During testing, no unexpected degradation in converter performance was observed. The TFE has been removed from the test stand and returned to Scientific Industrial Association {open_quote}{open_quote}LUCH{close_quote}{close_quote} for materials analysis and report. This research was conducted at the Thermionic System Evaluation Test (TSET) Facility at the New Mexico Engineering Research Institute (NMERI) as a part of the Topaz International Program (TIP) by the Air Force Phillips Laboratory (PL). {copyright} {ital 1996 American Institute of Physics.}

How to manage without being a manager  

SciTech Connect

In the author`s current position at Sandia National Laboratories within the Pulsed Power Sciences Center, much of the author`s time is spent in composing short (one page) technical reports and long (> 20 page) technical contracts and program plans for transmission to the Department of Energy and to upper management and also in reviewing long technical documents for accuracy. A major requirement of these efforts is to complete them on a timely basis, often within a few hours or a few days. In this talk, the author reveals some communication {open_quotes}secrets{close_quotes} that have been learned. The idea behind these twelve {open_quotes}secrets{close_quotes} is to get the answers you, as a nonmanager, need quickly from a manager without creating stress either on your part or the manager`s part.

Internet and the national nuclear data center  

SciTech Connect

The National Nuclear Data Center (NNDC) has been providing electronic access to the nuclear data bases it maintains since 1986. Originally the access was via modem and DecNet; primary access now is through the Internet. After the Internet became widely available to the scientific community, retrievals from the NNDC`s data bases have risen almost exponentially with an estimated 124,000 retrievals for 1996. Primary access is still through TELNET but there is substantial activity through the World Wide Web (W3). A current goal of the Center is to provide W3 access to all of its major data bases by the end of 1997. W3 access to the NNDC data bases will be demonstrated along with demonstrations of {open_quotes}work in progress.{close_quotes} The Center has also taken the initiative to develop and maintain new data bases covering the {open_quotes}frontiers{close_quotes} of nuclear science.

Saturday effects in tanker oil spills  

SciTech Connect

This paper documents a [open quotes]Saturday effect[close quotes] in the timing of tanker oil spills -- certain types of spills happen much more frequently on this day than one would expect if the spills were uniformly distributed. The phenomenon is restricted to Europe and North America, and is associated with [open quotes]vessel guidance[close quotes] accidents -- groundings, collisions, and rammings. Eliminating the Saturday effect would reduce tanker oil spills by around 163,000 gallons per year. Several policy responses are considered, including a Saturday harbor tax. A lower bound for an efficient tax is estimated to be $780 for a 20 million gal cargo. 23 refs., 2 figs., 3 tabs.

Charm production in flux tubes  

SciTech Connect

We argue that the nonperturbative Schwinger mechanism may play an important role in the hadronic production of charm. We present a flux tube model which assumes that the colliding hadrons become color charged because of gluon exchange, and that a single nonelementary flux tube is built up as they recede. The strong chromoelectric field inside this tube creates quark pairs (including charmed ones) and the ensuing color screening breaks the tube into excited hadronic clusters. In their turn these clusters, or {open_quote}{open_quote}fireballs,{close_quote}{close_quote} decay statistically into the final hadrons. The model is able to account for the soft production of charmed, strange, and lighter hadrons within a unified framework. {copyright} {ital 1996 The American Physical Society.}

Asynchronous neoglaciation and holocene climatic change reconstructed from Norwegian glaciolacustrine sedimentary sequences  

SciTech Connect

Sedimentary sequences from glacial lakes in southern Norway provide a new approach to the reconstruction of a relatively complete record of Holocene glacier and climatic variations. The data show that, following the [open quotes]Climatic Optimum[close quotes] of the early Holocene, neoglaciation was asynchronous: glaciers formed at different times at different sites, depending on critical altitudinal thresholds in relation to the scale of climatic variations. Neoglaciation began as early as ca. 6400 yr B.P. at Gjuvvatnet, ca. 3400 yr B.P. at Midtivatnet, and later than ca. 1000 yr B.P. at Storevatnet. These differences in glacierization provide a key to reconstructing the fluctuating decline in mean summer temperature (relative to the present) from at least +1 [degrees]C during the mid-Holocene to below -2 [degrees]C in the [open quotes]Little Ice Age[close quotes]. 34 refs., 4 figs.

Development of standardized air-blown coal gasifier/gas turbine concepts for future electric power systems. Volume 5, Appendix D: Cost support information: Final report  

SciTech Connect

The cost estimate provided for the DOE sponsored study of Air Blown Coal Gasification was developed from vendor quotes obtained directly for the equipment needed in the 50 MW, 100 MW, and 200 MW sized plants and from quotes from other jobs that have been referenced to apply to the particular cycle. Quotes were generally obtained for the 100 MW cycle and a scale up/down factor was used to generate the cost estimates for the 200 MW and 50 MW cycles, respectively. Information from GTPro (property of Thermoflow, Inc.) was used to estimate the cost of the 200 MW and 50 MW gas turbine, HRSG, and steam turbines. To available the use of GTPro`s estimated values for this equipment, a comparison was made between the quotes obtained for the 100 MW cycle (ABB GT 11N combustion turbine and a HSRG) against the estimated values by GTPro.

Dynamics of the Ginzburg-Landau equations of superconductivity  

SciTech Connect

This article is concerned with the dynamical properties of solutions of the time-dependent Ginzburg-Landau (TDGL) equations of superconductivity. It is shown that the TDGL equations define a dynamical process when the applied magnetic field varies with time, and a dynamical system when the applied magnetic field is stationary. The dynamical system describes the large-time asymptotic behavior: Every solution of the TDGL equations is attracted to a set of stationary solutions, which are divergence free. These results are obtained in the {open_quotes}{phi} = -{omega}({gradient}{center_dot}A){close_quotes} gauge, which reduces to the standard {close_quotes}{phi} = -{gradient}{center_dot}A{close_quotes} gauge if {omega} = 1 and to the zero-electric potential gauge if {omega} = 0; the treatment captures both in a unified framework. This gauge forces the London gauge, {gradient}{center_dot}A = 0, for any stationary solution of the TDGL equations.

Limits on expanding relativistic shells from Gamma-Ray Burst temporal structure  

SciTech Connect

The author calculates the expected envelope of emission for relativistic shells under the assumption of local spherical symmetry. Gamma-Ray Burst envelopes rarely conform to the expected shape, which has a fast rise and a smooth, slower decay. Furthermore, the duration of the decay phase is related to the time the shell expands before converting its energy to gamma rays. From this, one can estimate the energy required for the shell to sweep up the ISM. The energy greatly exceeds 10{sup 53} erg unless the bulk Lorentz factor is less than 75. This puts extreme limits on the {open_quotes}external{close_quotes} shock models. However, the alternative, {open_quotes}internal{close_quotes} shocks from a central engine, has one extremely large problem: the entire long complex time history lasting hundreds of seconds must be postulated at the central site.

Using micro saint to predict performance in a nuclear power plant control room  

SciTech Connect

The United States Nuclear Regulatory Commission (NRC) requires a technical basis for regulatory actions. In the area of human factors, one possible technical basis is human performance modeling technology including task network modeling. This study assessed the feasibility and validity of task network modeling to predict the performance of control room crews. Task network models were built that matched the experimental conditions of a study on computerized procedures that was conducted at North Carolina State University. The data from the {open_quotes}paper procedures{close_quotes} conditions were used to calibrate the task network models. Then, the models were manipulated to reflect expected changes when computerized procedures were used. These models` predictions were then compared to the experimental data from the {open_quotes}computerized conditions{close_quotes} of the North Carolina State University study. Analyses indicated that the models predicted some subsets of the data well, but not all. Implications for the use of task network modeling are discussed.

Small angle neutron scattering studies of coal-extract solutions  

SciTech Connect

Interest in the physics and chemistry of coal extracts has extended for over 100 years. Early on it was recognized that pyridine was a particularly good solvent capable of extracting a significant weight percent of intermediate rank coals. Many of the current theories regarding the macromolecular structure of coals (type III kerogens) are based on the fact that there exists a physically definable limit in the extractability of soluble organics from coal in pyridine. The non-extractable residue is generally considered to be a cross-linked macromolecular network. The extract-solvent {open_quotes}solutions{close_quotes}, although acknowledged to be far from ideal (thermodynamically), are presumed to be {open_quotes}molecular solutions{close_quotes} in the sense that random mixing of the constituents occurs within a single solution phase. This research set out to characterize the solution structures of coal extracts to gain insight into the nature of coal-solvent interactions.

Robotics at PSE&G: The cutting edge  

SciTech Connect

Public Service Electric & Gas Company`s robotics program, which started its momentum in the mid-1980s, has demonstrated a cost-benefit ratio of 1:3 from use of the technology at the utility`s three nuclear power units, Salem-1 and-1, and Hope Creek. During PSE&G`s first five-year nuclear robotics plan, from April 1986 through December 1991, {open_quotes}we spent R1.6 million, but we saved $5.3 million,{close_quotes} declared Harry T. Roman, principal engineer/PSE&G robotics and artificial intelligence program manager. {open_quotes}That`s one buck in, three bucks out.{close_quotes} A third of the savings came from reduced dose, a third from fewer person-hours, and a third from decreased plant down-time. This report discusses the development and nuclear/applications of robots at PSE&G.

Lyondell`s new isobutylene route could fuel an MTBE capacity boost  

SciTech Connect

Driven by the hot growth prospects for methyl tert-butyl ether (MTBE), Lyondell Petrochemical (Houston) has developed a route to isobutylene it claims can produce the MTBE feedstock at half the capital cost of alternative synthesis technology. If proved, the process will be used in a new 7500-10,000 bbl/day MTBE plant at Channelview, TX. Lyondell also hopes to license the technology. {open_quotes}With expanding MTBE capacity, we will have to have new routes to isobutylene,{close_quotes} says Bob G. Gower, president and CEO of Lyondell. {open_quotes}We think this is a good fit within Lyondell, but also that it is important technology.{close_quotes} Gower declines to detail its specifics, but says it is a one-step isomerization of n-butenes to isobutylene. The firm has tested the process at a pilot unit and plans a demonstration unit in 1992.

Energy grades and economic growth  

SciTech Connect

In 1709 William Darby invented the coking process that led to the use of coal in eighteenth century England. From an economic standpoint, one could say that this event more than any other ushered in the industrial revolution with its dependence on coal and steel produced with coal. However, from an engineering perspective, there is another cause of the industrial revolution that is more subtle-the physical makeup of the energy resources available to England. According to Simon Kuznets, an economic epoch, i.e., a period of time defined by rapid population increase for a given region, {open_quotes}is determined and shaped by the application and ramification of an {open_quote}epochal{close_quote} innovation{close_quotes}, in other words, new significant technologies.

Quantum Privacy Amplification and the Security of Quantum Cryptography over Noisy Channels  

SciTech Connect

Existing quantum cryptographic schemes are not, as they stand, operable in the presence of noise on the quantum communication channel. Although they become operable if they are supplemented by classical privacy-amplification techniques, the resulting schemes are difficult to analyze and have not been proved secure. We introduce the concept of quantum privacy amplification and a cryptographic scheme incorporating it which is provably secure over a noisy channel. The scheme uses an {open_quote}{open_quote}entanglement purification{close_quote}{close_quote} procedure which, because it requires only a few quantum controlled-not and single-qubit operations, could be implemented using technology that is currently being developed. {copyright} {ital 1996 The American Physical Society.}

Forecasting methodologies: The sixth generation  

SciTech Connect

In the 1990s an electric utility must be able to conduct three types of forecasting analyses: (1) an assessment of the future trend in electric usage in its service area that reflects likely sociodemographic, economic, and energy price trends, (2) the development of scenarios to bridge the uncertainty surrounding the likely future trend, and (3) a rapid-turnaround impact assessment of new technologies, government standards, utility programs, and competitor activities in a deregulated electric utility business environment. For a variety of reasons including accuracy and regulatory credibility, utilities need to conduct these three types of analyses using a consistent framework. This paper reviews the evolution of five earlier frameworks, or {open_quotes}generations,{close_quotes} of forecasting methodologies during the past four decades, then sketches a silhouette of a consistent {open_quotes}sixth-generation{close_quotes} framework.

CERCLA reauthorization 1994: Insuring the cleanup of hazardous substance pollution  

SciTech Connect

Authorizing legislation for the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ({open_quotes}CERCLA{close_quotes} or, more popularly, {open_quotes}Superfund{close_quotes}) will expire September 30, 1994. Enacted more than a decade ago, the CERCLA program is ripe for scrutiny prior to reauthorization. The following questions deserve consideration: has the CERCLA program accomplished its goals, do the benefits of the CERCLA program justify the costs involved, and what administrative or legislative changes will maximize the benefits of the CERCLA program as compared to its costs. Definitive answers to these questions may be impossible to ascertain, but by focusing on basic risk management principles and the issue of insurance coverage for CERCLA cleanups, this article illustrates that inefficiencies and unnecessary costs will plague the cleanup program until CERCLA`s site-specific, strict, retroactive, and joint and several liability scheme is discarded. 78 refs.

MarketBayes: A distributed, market-based Bayesian network  

SciTech Connect

This paper presents initial work on a system called MarketBayes, a computational market economy where distributed agents trade in uncertain propositions. For any Bayesian network, we have defined a corresponding economy of goods, consumers and producers that essentially {open_quotes}computes{close_quotes} the same information. Although our research thus far has only verified the existence of a market structure capable of Bayesian calculations, our hope is that such a system may address a variety of interesting problems of distributed uncertain reasoning. For example, the economic framework should be well suited for belief aggregation, since the bids of numerous agents with varying beliefs, confidence levels and wealth are concisely {open_quotes}summarized{close_quotes} in the going prices of goods.

Determination of minimal test sample size for high accuracy laser damage testing  

SciTech Connect

This paper presents an argument leading to estimate the minimal acceptable test sample size. In most cases the size of the test sample determines the number of possible test sites, since the other factors are usually fixed by test procedure. If the sample is too small, not enough data points are available and the resulting execution of an ISO standard or equivalent test, returns inaccurate and imprecise results. By use of a computer based model, a {open_quotes}single{close_quotes} optic is repeatedly tested and the results plotted versus sample size. This data is used to determine the curve of test accuracy as a function of sample size. The paper concludes with some {open_quotes}rules of thumb{close_quotes} for determining the minimum acceptable test sample size for a given level of desired accuracy.

Application of SAFIRE in the design of an emergency relief vent for a storage vessel  

SciTech Connect

For a gas-producing (gassy) decomposition reaction with established kinetics, SAFIRE (Systems Analysis For Integrated Relief Evaluation) is applied to design pressure relief vents for two storage vessels. The reactant concentration in the solvent differs significantly between the two vessels. SAFIRE is employed to validate experimentally derived kinetics through simulation of the reaction`s concentration, temperature and pressure history in the testing apparatus. Following this, SAFIRE is then applied to determine safe vent sizes for commercial-scale vessels. For the particular system under study, {open_quotes}hybrid/tempered{close_quotes} or {open_quotes}hybrid/nontempered{close_quotes} behavior may be observed, depending on the reactant concentration. The results for these two systems are compared. The utility and flexibility of SAFIRE are also demonstrated. 17 refs., 23 figs., 2 tabs.

The potential dependence of porous silicon electroluminescence  

SciTech Connect

The observation of visible luminescence from porous silicon has resulted in strong interest in this material. It has been demonstrated that the electrochemical reduction of persulfate ions at a porous silicon electrode/electrolyte interface may lead to intense luminescence (electroluminescence). Further, it has been found that the intensity and wavelength of the electroluminescence is potential dependent, this phenomenon is termed {open_quotes}potential tuning{close_quotes}. This paper is concerned with the elucidation of the mechanism of electroluminescence potential tuning. It will be shown that the process is related to the particle size distribution and the dynamics of electron transfer between the bulk silicon substrate, the surface silicon nanocrystals and the electrolyte. Further, the results of combined in-situ FTIR and electroluminescence studies will be reported. The influence of surface chemistry on the electroluminescence will be discussed with reference to the proposed {open_quotes}tuning{close_quotes} mechanism.
