    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.

    1994-09-01

    We report four cases of fragile X males with a {open_quotes}mosaic{close_quotes} pattern as detected by Southern blot analysis with probe StB12.3. These four {open_quotes}mosaics{close_quotes} are peculiar as full mutations are observed without premutations but rather associated with an EcoRI-EagI fragment of normal or reduced size. We have sequenced the fragment of reduced size and determined that the CGG repeats were missing as part of a 99 bp deletion with respect of the published FMR-1 gene sequence. Otherwise, the three other cases showed, in association with full mutations, a fragment of normal size including the CGG repeats. These cases did not show any premutation in association to their full mutations but rather normal or subnormal fragments where part or all of the CGG repeats were deleted at some time, most probably from a full mutation since premutations are known to be much more stable somatically. These cases raise the question whether usual {open_quotes}mosaic{close_quotes} cases (full + premature) are generated from the absence of postzygotic expansion of a premutation transmitted as such by the carrier mother or from a deletion of a full mutation during their period of somatic instability. Furthermore, these cases of {open_quotes}normal + full mosaics{close_quotes}, even if rare, challenge the usual DNA-based diagnostic means as the presence of a normal-sized fragment in part of the cells may be falsely interpreted as a normal genotype with catastrophic consequences in a context of prenatal diagnosis. This suggests again that Southern blotting with overexposure may be the preferred diagnostic method.

    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.

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.

    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.

    The [open quotes]tank farm[close quotes] for storing nuclear waste at the Hanford, Washington plutonium production complex has been a safety concern for some time. Special attention has been paid to a particular tank known as 101-SY, which periodically burps a witches' brew of chemicals. Concerns have been voiced that this tank presents an explosion hazard. Three years ago the Energy Department agreed to improve the monitoring of the 53 storage tanks considered most dangerous. In February, however, Oregon Congressman Ron Wynden made public the Energy Department's internal [open quotes]Red Team[close quotes] report on the Hanford waste tanks. The unencouraging findings of the Red Team are briefly outlined in this article. Included are reports of numerous failures of tank monitoring equipment, but also findings that the tanks are being monitored more frequently than previously.

    By partitioning quoted depth into the specialist's contribution and the limit order book's contribution, the paper investigates whether specialists manage quoted depth to reduce adverse selection risk. The results show that both specialists and limit order traders reduce depth around information events, thereby reducing their exposure to adverse selection costs. Moreover, specialists' quotes may reflect only the limit order book

    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.

    We have utilized a {open_quote}{open_quote}multilayer{close_quote}{close_quote} monochromator (a pair of layered synthetic microstructures) in small-angle x-ray scattering/diffraction studies of biological materials. Many biological applications of the SAXS/D technique, in particular time-resolved studies, are often limited by the flux available to experiments. The wider energy bandpass of the multilayer monochromator provides a higher beam flux by a factor of 10 or more, compared with that of the Si(111) double-crystal monochromator. At the SSRL BL 4-2 SAXS/D facility, two types of multilayers have been used: Mo/C on Si substrate, fabricated at Lawrence Berkeley Laboratory [S. Brennan {ital et} {ital al}., Nucl. Instrum. Methods Phys. Res. A {bold 347}, 417 (1994)] and Mo/B4C on Si substrate, obtained from Osmic, Inc. The energy bandpass of the former multilayer is about 150 eV at 10 keV, and that of the latter is expected to be slightly wider. A pair of the latter multilayers gives 8 x 10{sup 11} photons/s in a beam size 1 x 2 mm{sup 2} (FWHM) at a photon beam energy of 9 keV and a SPEAR ring current of 85 mA. We will present excellent quality diffraction/scattering patterns from muscle fibers and protein solutions that show no significant smearing artifacts due to the wider energy bandpass. {copyright} {ital 1996 American Institute of Physics.}

    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.

    The subsurface [open quotes]Millerella[close quotes] and Carter sandstones (middle Chesterian) of the Black Warrior basin represent the highest units of the thick Muldon clastics deltaic facies tract. Lowstand marine conditions during Carter deposition allowed for southeastwardly progradation of five distinct deltaic lobe complexes onto the stable northern shelf of the basin. With each of these lobes, both an [open quotes]A[close quotes] (upper) and a [open quotes]B[close quotes] (lower) reservoir unit can be identified. The [open quotes]B[close quotes] sandstone produces from delta-front sheet sands, channel-mouth bars, and possible bar fingers of river-dominated deltas. The more prolific [open quotes]A[close quotes] subdivision contains reservoirs in upper delta-plain point bars, crevasse splays, and distributary channel fills. The most easterly of the lobes, preserved in the Bean's Ferry field of Itawamba County, comprises an amalgamated valley-fill facies that removed a maximum of 250 ft (76 m) of lower Bangor platform carbonates. In contrast, the [open quotes]Millerella[close quotes] sandstone is a series of unconnected pods that formed as marine-reworked sand bodies during a eustatic rise in sea level. The average detrital sand grain composition for four cores taken in Monroe County is 94.7% monocrystalline quartz, 2.9% polycrystalline quartz, 1.6% albite feldspar, 0.1% low-rank metamorphic rock fragments, 0.5 chert, and 0.2% muscovite. These data indicate that neither the Ozark uplift nor the Ouachita orogen could have acted as the principal source area for the Carter and [open quotes]Millerella[close quotes] sandstones. More likely, the sedimentary-igneous terrains along the northern margin of the Illinois basin served this function. A major eustatic lowstand brought this mineralogically mature sediment across the Illinois basin through incised valleys to the northern self of the Black Warrior basin.

    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.}

    Recently approved US legislation and a new US administration have brought an end to 12 years of American opposition to a comprehensive test ban (CTB).

    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.

    By no means the least important fault that can develop in coke-oven refractories, and which lowers the productivity and shortens the life of coke-oven batteries is the development of so-called {open_quotes}undercuts,{close_quotes} whereby longitudinal fissures of variable depth and length appear in the first one or two rows of bricks form the floor. On the other hand, large-scale undercutting only develops in individual batteries, and many coking plant workers employed in the servicing and upkeep of the coke ovens are unfamiliar with the problem. No convincing explanation has yet been forthcoming, and consequently no effective measures have been laid down for its prevention. The first large-scale outbreak of undercutting in this country occurred in 1956-1957, in No. 1-4 batteries (side heating) at the Kuznetsk and Magnitogorsk II & SW-plants. 2 refs., 3 tabs.

    Partial-Order Causal Link planners typically take a {open_quotes}least-commitment{close_quotes} approach to some decisions (notably, step ordering), postponing those decisions until constraints force them to be made. However, these planners rely to some degree on early commitments in making other types of decisions, including threat resolution and operator choice. We show why existing planners cannot support full least-commitment decision-making, and present an alternative approach that can. The approach has been implemented in the Descartes system, which we describe. We also provide experimental results that demonstrate that a least-commitment approach to planning can be profitably extended beyond what is done in POCL and similar planners, but that taking a least-commitment approach to every planning decision can be inefficient: early commitment in plan generation is sometimes a good idea.

    A shaped charge (81 mm, 42{degrees}, OFHC copper cone) was fired into a {open_quotes}soft{close_quotes} recovery bunker to allow metallurgical examination of recovered jet particles and the slug. The initial weight of the copper liner was 245 gm, of which 184 gm was recovered. The number of jet particles recovered was 37 (approximately 63% of the particles formed by the charge). Extensive metallurgical analyses were performed on the recovered slug and jet particles. The microstructural features associated with voids, e.g. dendritic grain growth, clearly indicate that the regions in the vicinity of the centerline of the slug and jet particles were melted. In this work we present calculations of jet temperature as a function of constitutive behavior. In order to predict melt in the center region of the jet we find it necessary to scale flow stress with a pressure dependent shear modulus.

    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.

    Onset in thermoacoustic engines, the transition to spontaneous self-generation of oscillations, is studied here as both a dynamical critical transition and a limiting heat engine behavior. The critical transition is interesting because it occurs for both dissipative and conservative systems, with common scaling properties. When conservative, the stable oscillations above the critical point also implement a reversible engine cycle satisfying Carnot{close_quote}s theorem, a universal conservation law for entropy flux. While criticality in equilibrium systems is naturally associated with symmetries and universal conservation laws, these are usually exploited with global minimization principles, which dynamical critical systems may not have if dissipation is essential to their criticality. Acoustic heat engines furnish an example connecting equilibrium methods with dynamical and possibly even dissipative critical transitions: A reversible engine is shown to map, by a change of variables, to an equivalent system in apparent thermal equilibrium; a Noether symmetry in the equilibrium field theory implies Carnot{close_quote}s theorem for the engine. Under the same association, onset is shown to be a process of spontaneous symmetry breaking and the scaling of the quality factor predicted for both the reversible {ital and irreversible} engines is shown to arise from the Ginzburg-Landau description of the broken phase. {copyright} {ital 1998} {ital The American Physical Society}

    In the design of superconducting magnet elements, such as may be required to guide and focus ions in a particle accelerator, one frequently premises some particular current distribution and then proceeds to compute the consequent magnetic field through use of the laws of Blot and Savart or of Ampere. When working in this manner one of course may need to revise frequently the postulated current distribution before arriving at a resulting magnetic field of acceptable field quality. It therefore is of interest to consider an alternative ({open_quotes}inverse{close_quotes}) procedure in which one specifies a desired character for the field required in the region interior to the winding and undertakes then to evaluate the current distribution on the specified winding surface that would provide this desired field. By evaluating the specified potential in the region interior to the winding along the interface, the authors have determined that a relaxation solution to the potential in the region outside the winding can be converged and used to calculate wire location. They have demonstrated this method by applying a slightly modified version of the program POISSON to a periodic alternating sinusoidal quadrupole field.

    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.

    Previous linkage studies have assigned a gene for non-syndromic X-linked mental retardation (XMR) to at least 8 different regions on the X-chromosome. The fragile X-syndrome (FRAXA) does not account for more than 40% of all cases; in most XMR families early diagnosis and prevention is not possible. 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.

    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.

    China`s central political authorities have constructed a system which is designed to enable them to exert their personal influence and control over each level of every organization in the country -- both civil and military. The Communist Party of China (CPC) is represented at all levels of each and every organization, including the People`s Liberation Army (PLA). These Party entities are intended to both provide oversight and to ensure that Party policies, directives and orders are obeyed. This penchant for political control, which may have its roots in China`s imperial past, appears to have been reinforced by the early developmental path chosen by the Party`s leadership. Current attempts aimed at maintaining political control of its resources, especially the military, are embodied in the formal system of {open_quotes}Political Work.{close_quotes} In the PLA, this system of political control results in the involvement of political organs in day-to-day military matters to an extent unheard of in the West.

    Mucopolysaccharidosis type II (Hunter syndrome), iduronate-sulfatase (IDS) deficiency, is an X-linked disorder. Analysis of genomic DNA and cDNA from a total of 60 patients was performed in our laboratory during the last two years. In each case the gene defect was identified, resulting in 41 different mutations, including nonsense, missense, and splice site-point mutations, deletions of various sizes, and a 14 bp duplication. While in only 20% of the patients the whole IDS gene is deleted or largely altered, in about 80% of the cases small deletions (up to 17 bp) and point mutations were found. Of the 9 IDS gene exons, exons III, VIII, and IX harbor 78% of all point mutations, whereas 35% of these latter were found in exon III. Obviously, codon 374 in exon VIII is another mutation {open_quotes}hot spot{close_quotes} as the same point mutation has been found in 7 unrelated patients. Two further {open_quotes}hot spots{close_quotes} are at codons 443 and 468 in exon IX with five different mutations each. Remarkably, all mutations in exon III were found to be heterozygous in the genomic DNA but not in the IDS cDNA of the patients. Of the more than 200 unaffected male controls studied by us, two are heterozygotes for two different point mutations in exon III. Contamination of the samples can be excluded and we hypothesize the existence of a pseudogene that consists of at least exon III. As three patients with submicroscopic deletion and Hunter syndrome show no IDS hybridization signal in Southern analysis, we speculate that the putative pseudogene is in the neighborhood of the functional gene.

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.

To begin remedying that situation, the communications staff of Pacific Northwest Laboratory, a multiprogram national laboratory located in Richland, Wash., planned and hosted a one-day {open_quotes}Quest for Quality{close_quotes} seminar. The seminar was the first of its kind to comprise technical communications professionals from all the local DOE prime contractors, including technical editors and writers, publications assistants, text processors, and document production staff. The goals of the seminar were to identify ways to improve the quality of Hanford`s communication products and processes, to strengthen ties among technical communications staffs, and to open the lines of communication for future collaborative efforts. An eight-person committee selected topics, arranged facilities, recruited speakers, coordinated activities, hosted the seminar, and prepared proceedings.

    Based on the coherent electronic structure of the ideal crystal, the {open_quotes}giant{close_quotes} magnetoresistance (GMR) of UNiGa and U{sub 2}Pd{sub 2}X (X=In, Sn) at the field-induced transition from the antiferromagnetic ground state to the ferromagnetic state is calculated using linear transport theory. Assuming that the scattering is well represented by a single averaged relaxation time, good agreement with experimental data is obtained for the GMR of UNiGa. The effect can be understood from topological changes of particular Fermi surface sheets at the magnetic transition, bringing about conductivity changes of a factor of 2. No experimental data are available for the high-field resistivity of U{sub 2}Pd{sub 2}X. Here, in contrast to UNiGa, the Brillouin zone is invariant under the metamagnetic transition. Nonetheless, conductivity changes up to a factor of 2 are found, again caused by changed connectivity of the Fermi surface. Moreover, we predict the possibility of an inverse GMR effect for this system without introducing spin-dependent scattering. The latter is shown to have minor influence due to strong spin{endash}orbit coupling. {copyright}{ital 1997 American Institute of Physics.}

    Recently, Greene (1992) analyzed vehicle miles travelled for U.S. passenger vehicles over 1966-89 to econometrically estimate the {open_quotes}rebound{close_quotes} effect in fuel consumption resulting from improved fuel efficiency. He found that a static AR(1) model could not be rejected, implying that the rebound effect is small (13%) with no significant long-run adjustments, regardless of the assumed functional form (linear or loglinear). Another look at the data from a different model selection approach shows that while a loglinear AR(1) model is acceptable, the linear version is not. Using either form, a lagged dependent variable model cannot be rejected on statistical grounds yet has insignificant GNP effects, yielding similarly small short-run rebound effects but significant long-run rebound effects of about 30%. Thus, the evidence from these competing models for a significant long-run adjustment process is mixed, so that its presence cannot be completely ruled out. 13 refs., 2 tabs.

    The communications convergence, brought about largely by the digitalization revolution, is now moving in a double helix through the horizontal telecommunications hierarchy. Competition for customer premises is aspiring upward toward the competition that is spiraling downward from the long-distance market. The competitive-access market is growing rapidly. 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.

    The detector head for a dual headed {open_quotes}Universal Nuclear Medicine Imager{close_quotes} (UNMI) is designed. It is based on position sensitive (PS) area detectors fitted with a thick (0.75 inches) NaI(Tl) crystal. In order to make it {open_quotes}universal{close_quotes}, a means for determining the depth of interaction (DOI) in the crystal is devised. Crystal thickness is divided into two layers, each 3/8 inches thick, by insertion of a thin (0.03 inches) quartz (glass) layer; these layers added to the external lower and upper surfaces of crystal, too, form two internal {open_quotes}light collimator{close_quotes} (LC) channels by their reflectively (specular) polished couplings. These DOI channels, according to the light refraction / reflection law direct the light reflected from quartz layers (as exceeding a critical angle) through NaI(Tl) layers to the external parts of LC system; these are connected via quartz optical cables to the DOI determining PM tubes. DOI electronics including a coincidence circuit, connecting signals from conventional PS and DOI PM tubes arrays, identifies a DOI layer and shifts an, x, y, address to the particular DOI memory stack. The UNMI design is likely to retain spatial resolution of PS detectors - gamma cameras for low energy single photon emitters and to improve spatial resolution in PET studies done by PS detectors fitted with thick NaI crystals, enabling a proper correction for parallax error.

    The problem of source identification of anthropogenic pollutants in a local marine environment has been intensively studied during the last two decades. Recently we have started intensively using an approach, called by us the [open quotes]fingerprints[close quotes] approach, for tracing anthropogenic pollutant sources and for the description of various geochemical and chemical processes related to contamination by anthropogenic heavy metals in the marine environment. This approach was based on the assumption that if anthropogenic pollutants for any particular area had originated from the same source, then the pairwise relationships between the concentrations of these pollutants in sediments from various stations in the contaminated area would be linear. The discussed approach was applied to the case study of heavy metal contamination of the estuarine environment of the Kishon River (Israel). The [open quotes]fingerprints[close quotes] approach can be successfully used for source contamination assessments even when there is significant trace metal fractionation or sediment fractionation in an area under study. However, in these cases this approach should be applied to each sediment fraction separately. The distribution of various heavy metal [open quotes]fingerprints[close quotes] for sediments from the case study of the Kishon River estuary and from the marine area close to the estuary have been used for the explanation of heavy metal redistribution on Kishon sediments consisting of a high fraction of anthropogenic fluorite after the contact of these sediments with seawater. 23 refs., 2 figs., 3 tabs.

    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.

    The risk for fragile X {open_quotes}gray-zone{close_quotes} alleles to expand appears to depend on the absence of stabilizing AGGs, which interrupt the CGG repeat region. To characterize such alleles better, we analyzed a series of 101 chromosomes with triplet repeat lengths ranging from 35 to 59 for variations in their AGG interspersion patterns. Among these, 11.9% had 3 AGGs, 59.3%, had 2, 24.8% had 1, and 4.0% had 0. An inverse relationship between FMR1 repeat length and the number of interrupting AGGs was observed. Within the range of 35-44 repeats, 98.7% of alleles were found to have a pure CGG repeat length (P{sub CGG}) of less than 33. However, among alleles with 45-59 repeats, 50% were found to have 0 or 1 AGG and a P{sub CGG} of more than 33. Thus, gray-zone alleles with 45-59 repeats frequently have a long stretch of pure CGGs and thus are more likely to be unstably inherited than alleles with 35-44 repeats. We found length associations of P{sub GCC} with 2 flanking microsatellites, DXS548 and FRAXAC 1: a P{sub CGG} < 20 was strongly associated with haplotype 20-19, whereas a P{sub GCC} > 20 was more strongly associated with the haplotype 25-21. This result could reflect a founder effect or a generalized instability of CGGs and microsatellites. 28 refs., 2 figs., 4 tabs.

    Five years have passed since US EPA adopted the now well-known hierarchy for management of MSW - source reduction, recycling, waste-to-energy, and, for waste that cannot be practically recycled or combusted, landfilling. Despite US EPA`s preferred waste-management hierarchy, the United States, as a country, continues to rely on landfilling as its principal means of MSW management. This disparity is also true locally, in the case of the nation`s most populous city, New York City. The City deposits most residential MSW in its Fresh Kills Landfill on Staten Island, some four million tons of MSW per year. What is more, while the City is indeed implementing recycling, its formal waste-management plans also call for continued heavy reliance on the Fresh Kills Landfill for 10 years or more into the future. Because landfills continue to serve as the MSW management {open_quotes}workhorse{close_quotes} in many locales, it is believed that a full accounting of landfill environmental emissions is called for, to enable adequate environmental safeguards in the design of landfills, appropriate regulation of landfill environmental emissions, and informed public decision-making about MSW management in general. Evidence is presented that air pollutant emissions, in particular, from landfills pose a significant environmental threat that is largely unrecognized by most people. Locally in New York City, there is an awakening to the issue of landfill air-pollutant emissions, as evidenced by the recent undertaking of a study of air quality near the Fresh Kills Landfill by Federal, State, and local agencies. In general, however, the public`s concern over landfill air-pollutant emissions is limited to odor nuisance.

    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.

    Fluid-flow properties of porous media, such as permeability k and irreducible water saturation S{sub wi}, can be estimated from water {sup 1}H nuclear magnetic resonance (NMR) relaxation data, but there are basic questions regarding data processing and interpretation. We found that S{sub wi} and k are better estimated if different forms of {open_quotes}average{close_quotes} relaxation time are used. NMR longitudinal relaxation data for a suite of 106 water-saturated clean sandstones were used. Sandstones represent a specialized class of porous media, where even for small porosity, substantially all pore space is connected. The sandstones exhibit distributions of relaxation times ranging over factors from at least 10 to more than 10{sup 3}. We tried several forms of {open_quotes}average{close_quotes} relaxation time T. One family of Ts is {l_angle}T{sup p}{r_angle}{sup 1/p}, where limp{r_arrow}0 gives the geometric mean. The best estimator we found for S{sub wi} uses a form of average relaxation time {ital only}, rather than relaxation time cutoff. The time used can be any of several forms of T, giving more emphasis to {ital short times} than the geometric mean does. On the contrary, the best T for estimating permeability without other information is precisely the geometric mean. The best estimates of permeability came from fits of ln(k/{phi}) using Ts with emphasis at {ital slightly longer times}. While S{sub wi} is better estimated by using all the data points (starting from our minimum 0.4 ms), k is better estimated by starting at a few ms, that is by ignoring a {ital non-negligible} fraction of the signal for some samples. These results can be obtained also by using computations that do not need to invert multiexponential relaxation data, and good results are obtained even with only a few data points.

    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. This paper presents the major compatibility issues of the potential payloads for the USA/9904/B(U)F-85 RTG Transportation System for the {open_quotes}Pluto Express{close_quotes} mission. {copyright} {ital 1997 American Institute of Physics.}

    Hunter syndrome is an X-linked recessive, lethal disease resulting from deficiency of iduronate-2-sulfatase (IDS) catalytic activity. Because of low reproductive fitness, most affected individuals are expected to have new mutations. Most of such defects are anticipated to be single base pair (bp) changes; however, several previous studies utilizing Southern analysis of RT-PCR have identified numerous large gene deletions in patients having the {open_quotes}severe form{close_quotes} with neurologic disease. To investigate the spectrum of IDS mutations, we have developed a method of automated direct sequencing of RT-PCR products representing the entire IDS coding region. Of 19 patients studied by this approach, only 1 had an IDS coding region which did not contain a mutation; 1 had a single bp insertion; 1 had a 2 bp deletion; and 13 had single-base substitutions. Of the 13 having single base substitutions, 2 resulted in aberrant splicing. Only 1 patient had a complete gene deletion; in view of previous reports, there was a surprising lack of major gene deletions. Notably, a CpG dinucleotide at R468 was identified as a {open_quotes}hot spot{close_quotes} for mutation. Five unrelated individuals had substitutions at this site which thus accounted for 28% of all mutations in this series: R468W (3 patients) and R468Q (2 patients). MspI digestion provided a method of rapid diagnosis and determination of heterozygote status for such R468 mutations. Genotype-phenotype correlations in this R468 group are not yet possible because of confounding information, i.e., there are both {open_quotes}mild{close_quotes} and {open_quotes}severe{close_quotes} patients in this group and some have co-existing neurologic diseases. This approach of gene sequencing appears to be necessary, and sufficient, to characterize the vast spectrum of mutations in Hunter syndrome.

    A technique is presented for simple, effective log analysis of (Miocene) {open_quotes}Spellacy{close_quotes} sands and conglomerates of the Santa Margarita Formation at Midway-Sunset Field in Kern County, California. Results are shown graphically on the log display and are quantified for mapping. Requirements are digital wireline data -- in this simple case, just resistivity and porosities - and flexible log analysis software such as QLA2{trademark}. The first step of this technique discriminates between reservoir-quality and non-reservoir-quality intervals yielding three color-coded categories. A narrow color-filled column is added to the well log display to graphically communicate the vertical distribution of reservoir-quality and barrier intervals. The second step performs a fluid analysis on the reservoir-quality category (intervals) yielding three more color-coded categories. The results of the fluid analysis are graphically displayed in a second narrow color-filled column on the well log. Analysis results are captured from a tabular report for mapping. Quantifiable products include (1) thicknesses: original net pay, current net pay, reservoir quality, total sand, total porosity, phi-H, etc.; (2) averages: original net pay porosity; current net pay porosity, current net pay saturation, current net pay bulk volume oil, etc.; and (3) ratios: thickness of reservoir quality to total sand and thickness of current net pay to total interval.

    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.

    The marine demosponge Halichondria panicea Pallas, is a cosmopolitan species occurring in coastal waters with varied conditions of light, current, salinity and turbidity. H. panicea has a leuconoid structure and is composed of siliceous spicules and spongin fibers. Sponges are important members of many shallow water marine benthic communities, but comparatively little is known of their trace metal biology. Sponge architecture is constructed around a system of water canals and the physiology of the sponge is largely dependent on the currents of water flowing through their bodies. The volume of water pumped by a sponge is remarkable, ca. 100-1200 ml h[sup [minus]1] g[sup [minus]1]. This large volume of water passing through the body of a sponge means that most cells are in direct contact with the external medium. Many sponges are able to accumulate trace metals and are highly tolerant of such pollutants. This has led to the proposal that a [open quotes]sponge watch[close quotes] program be initiated supplementary to the existing [open quotes]mussel watch[close quotes] program. In view of the large volume of water passing through the bodies of sponges such as H. panicea, the suitability of this species as a biomonitoring organism was further investigated. This study describes the accumulation strategy of the demosponge H. panicea exposed to dissolved cadmium (Cd) and the effect of Cd upon sponge filtration rate.

    Coon Creek field is a significant petroleum reservoir in the [open quotes]Big Lime[close quotes], Middle to Upper Mississippian Newman equivalent, in southeastern Kentucky. Initial production from select wells has exceeded 600 bbl of oil/day at drilling depths averaging 915 m (3300 ft). Facies patterns, dolomitization, porosity, and structure in this carbonate reservoir have been delineated by geophysical logs, subsurface mapping, and examination of cores and cuttings. The reservoir is set within a localized paleotopographic low on the unconformable surface of the underlying siliciclastic Borden Group; the Borden surface can express rapid relief of over a 10% grade within less than 300 m. Transgression across the exposed Borden surface resulted in the deposition of a complex system of carbonates lithofacies. Crinoidal dolostones, representing shallow subtidal skeletal bars and banks, form the basal Big Lime (1.5-6 m thick). They are overlain by a typical facies (30 m thick) of bryozoan grainstones/packstones, crinoid grainstones, and mixed skeletal wakestones/mudstones. The rybryozoanacies are characterized by unfragmented fenestrates cemented by radiaxial-fibrous calcite. Stratigraphic distributions indicate the bryozoan facies were broad buildups with crinoidal flank and cap deposits and muddy skeletal off-mount facies, similar to deeper water Waulsortian mounds in other basins. Pellet and ooid grainstones represent moderate- to high-energy subtidal shoal deposits that covered the mound complex. Hydrocarbon production is restricted in the field to the crinoid-bryozoan facies complex within the basal 30 m. Reservoir porosity and permeability have been enhanced by selective dolomitization of grainstones and fracturing related to postdepositional reactivation of basement faults.

    The prospects are examined for the detection of a slow decay of the lightest neutralino (or any other long-lived particles) at the CERN LHC and at the Very Large Hadron Collider (VLHC). We first point out that such hadron colliders will become the {open_quotes}neutralino factory{close_quotes} producing 10{sup 6}{endash}10{sup 9}neutralinos/yr, if gluinos and/or squarks actually exist below O(1) TeV. The lightest neutralino ({tilde {chi}}{sub 1}{sup 0}), usually assumed to be stable, will be unstable if lighter superparticles such as the gravitino ({tilde G}) or axino ({tilde a}) exist, or R-parity is not conserved. The decay signal would, however, be missed in usual collider experiments, particularly when the decay mostly occurs outside the detector. In order to search for such a slow decay of {tilde {chi}}{sub 1}{sup 0}, we propose a dedicated experiment where the collision products are dumped by a thick shield, which is followed by a long decay tunnel. The decay product of {tilde {chi}}{sub 1}{sup 0} can be detected by a detector located at the end of the tunnel. The slow arrival time and the large off angle (to the direction of the interaction point) of the decay product will provide a clear signature of slowly decaying {tilde {chi}}{sub 1}{sup 0}{close_quote}s. One can explore the decay length (c{tau}) in a wide range, i.e., 0.2 m to 1{times}10{sup 5}km for m{sub {tilde {chi}}{sub 1}{sup 0}}=25GeV and 1 m to 2 km for m{sub {tilde {chi}}{sub 1}{sup 0}}=200GeV at the LHC. This corresponds to the range of the SUSY breaking scale {radical} (F) =2{times}10{sup 5} to 2{times}10{sup 7}GeV in case of the {tilde {chi}}{sub 1}{sup 0}{r_arrow}{gamma}{tilde G} decay predicted in gauge-mediated SUSY breaking models. At VLHC, one can extend the explorable range of m{sub {tilde {chi}}{sub 1}{sup 0}} up to {approximately}1000GeV, and that of {radical} (F) up to {approximately}1{times}10{sup 8}GeV. In the case of the {tilde {chi}}{sub 1}{sup 0}{r_arrow}{gamma}{tilde a} decay, the Peccei-Quinn symmetry breaking scale F{sub a} can be explored up to {approximately}5{times}10{sup 11}GeV. The mass of the decaying particle can be determined by using the correlation between the energy and the arrival time of the decay product. With the setup we propose, one can also search for (i) other decay modes of {tilde {chi}}{sub 1}{sup 0} such as the R-parity violating one, (ii) slow decays of any other long-lived neutral or charged particles, and (iii) heavy stable charged particles. {copyright} {ital 1997} {ital The American Physical Society}

The spectra were interpreted on the basis of the local symmetry of each metal carbonyl center. The positions of vCOs are determined by the mutual electronic effect of each center. CpmM(CO){sub n} groups are strong electron acceptors and cause an increase in vCOs of adjacent M(CO){sub n} groups. Cp(CO){sub n}M groups, being electron donors, cause a decrease in the frequencies of neighboring groups. In trinuclear complexes, the frequencies of the central Fe(CO){sub 2} group are not changed much due to the compensation of donor and acceptor influences of two neighboring substituents.

    We report here the results of a questionnaire survey of consultant clinical geneticists in the United Kingdom to which we had an 81% response rate. In this questionnaire we asked about: (1) the nature of services currently offered to families with hearing impaired children, (2) what recurrence risks they quoted in isolated non-syndromic cases, and (3) what they might suggest for improving the range of genetic services available at present. We noted great variation both in these services and in the recurrence risks quoted in isolated cases. Based on the results of the questionnaire, we have proposed a protocol for the investigation of permanent childhood hearing impairment, which we believe to be both comprehensive and practical in an outpatient clinic setting. It is only by improving existing clinical and social understanding and knowledge of childhood hearing impairment that it will become possible to use recent molecular advances to develop comprehensive and consistent services for these families.???Keywords: childhood hearing impairment; investigation; genetic; recurrence risks PMID:10051011

    The Atmospheric Release Advisory Capability (ARAC) program at the Lawrence Livermore National Laboratory (LLNL) was the U.S. Department of Energy atmospheric modeling resource used for the contingency of potential radiological releases during the launch of the Cassini mission. The ARAC Center at LLNL forecasted detailed weather conditions and delivered consequence assessments for potential accident scenarios to NASA before and during launch operations. A key aspect of ARAC{close_quote}s support was to acquire a variety of meteorological data for use in both forecast and real-time model calculations. ARAC acquired electronically two types of real-time observed meteorological data: 1) the full set of on-site towers and profilers via the Cape Canaveral Air Station (CCAS) Meteorological Interactive Data Display System (MIDDS), and 2) routine regional airport observations (delivered to the ARAC Center from the Air Force Weather Agency). We also used two forecasted data sources: 1) the U.S. Air Force 45th Weather Squadron at CCAS forecasted soundings for launch time, and 2) the Navy Operational Regional Atmospheric Prediction System (NORAPS) prognostic model which ARAC ran over the Cape. The NORAPS runs produced detailed 24-hr forecasts of 3-D wind fields. ARAC used default radiological accident source terms involving the potential destruction of Cassini{close_quote}s Radioisotope Thermoelectric Generators (RTGs) during 3 phases: 1) before the launch, 2) during the first 5 sec after ignition, and 3) from 5 to 143 sec after ignition.

    The hemagglutination inhibition antibody titers against the JC and BK polyoma viruses (JCV and BKV, respectively) are significantly elevated in individuals exhibiting {open_quotes}rogue{close_quotes} cells among their cultured lymphocytes. However, the elevation is so much greater with respect to JCV that the BKV elevation could readily be explained by cross reactivity to the capsid protein of these two closely related viruses. The JCV exhibits highly sequence homology with the simian papovavirus, simian virus 40 (SV40), and inoculation of human fetal brain cells with JCV produces polyploidy and chromosomal damage very similar to that produced by SV40. We suggest, by analogy with the effects of SV40, that these changes are due to the action of the viral large tumor antigen, a pluripotent DNA binding protein that acts in both transcription and replication. The implications of these findings for oncogenesis are briefly discussed. 45 refs., 1 fig., 3 tabs.

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%.

    The Clean Air Act was amended in 1990 and additional requirements were added to Title III {open_quotes}Air Toxics.{close_quotes} Title III identified one hundred eighty-nine hazardous air pollutants (HAPS) and Congress directed the EPA to study the effects of emissions of these HAPS on public health and the environment. EPA is to report to Congress in the fall of 1995 concerning their findings and make recommendations regarding fossil fuel fired combustion units. The outcome of the EPA recommendations will be of great interest to coal producers and users. Of the one hundred eighty-nine listed HAPS, eleven are trace metals found in coal. The producers and users may be required to analyze coal for these HAPS, to determine if selective mining and/or beneficiation can lower their occurrence, to determine their fate in the combustion process, etc. Indeed many coal companies have begun to study their reserves to aid the EPA investigation. Currently there are no EPA promulgated test methodologies for these elements in coal. Moreover, the American Society for Testing Materials (ASTM) does not provide standards for the analyses of all of the eleven HAPS either. In view of this lack of standardized analytical protocols the commercial laboratory is left with finding the best methods for meeting these analytical needs. This paper describes how Standard Laboratories, Inc. as a whole and particularly its Environmental Laboratory Division has met this need.

    Background Consensus on how to adequately measure patient satisfaction with health care is limited, and has led to the development of many questionnaires with various methodological problems. The objective of this study was to develop a liver disease- and care-specific patient satisfaction instrument on the basis of previously tested methodology in patient satisfaction measurement, the so called QUOTE- series: Quality Of health care services Through the patients' Eyes. QUOTE methodology aims to standardise the measurement of satisfaction as the discrepancy between patients' needs, and the extent to which these needs are being met. Methods As part of the QUOTE methodology routine, 11 Patients with chronic liver disease from the Erasmus MC (Rotterdam, the Netherlands) participated in focus-group meetings on patient satisfaction with the provided service at the outpatient hepatology clinic. Twenty-eight other patients were invited to rank the items generated during the focus-group meetings according to importance. With this information, the QUOTE-Liver was constructed. Face validity, construct validity, content validity, and reliability of the newly developed questionnaire were assessed in a test sample of 152 patients with chronic liver disease. Results Two liver-disease specific, and the 18 items ranked as most important were included in the QUOTE-Liver. Face validity and content validity were acceptable: neither patients (n = 152) nor psychologists (n = 3) or a hepatologist suggested any extra items to be included. Construct validity was good: the overall score correlated significantly with the Visual Analogue Scale (VAS) measuring overall satisfaction (r = 0.69, p < 0.01). The reliability of the QUOTE-Liver was excellent (? = 0.90). Conclusion The QUOTE-Liver is an easy to complete instrument based on standardized state-of-the-art satisfaction measurement methodology. Preliminary evidence for its validity and reliability was demonstrated. The QUOTE-liver covers those aspects of satisfaction that CLD patients consider to be important when visiting the outpatient department of hepatology. Even though further substantiating of the favourable psychometric findings is desirable, it seems to be a useful instrument that can be used to identify those aspects of care that need improvement in order to optimise the provision of health care for patients with chronic liver disease.

    Triplets of the form of purine, purine, pyrimidine (RRY(i)) are enhanced in frequency in the genomes of primates, rodents, and bacteria. Some RRY(i) are [open quotes]cryptic[close quotes] repeats (cRRY(i)) in which no one tandem run of a trinucleotide predominates. A search of human GenBank sequence revealed that the sequences of cRRY(i) are highly nonrandom. Three randomly chosen human cRRY(i) were sequenced in search of polymorphic alleles. Multiple polymorphic alleles were found in cRRY(i) in the coding regions of the genes for proopiomelanocortin (POMC) and TATA-binding protein (TBP). The highly polymorphic TBP cRRY(i) was characterized in detail. Direct sequencing of 157 unrelated human alleles demonstrated the presence of 20 different alleles which resulted in 29--40 consecutive glutamines in the amino-terminal region of TBP. These alleles are differently distributed among the races. PCR was used to screen 1,846 additional alleles in order to characterize more fully the range of variation in the population. Three additional alleles were discovered, but there was no example of a substantial sequence amplification as is seen in the repeat sequences associated with X-linked spinal and bulbar muscular atrophy, myotonic dystrophy, or the fragile-X syndrome. The structure of the TBP cRRY(i) is conserved in the five monkey species examined. In the chimpanzee, examination of four individuals revealed that the cRRY(i) was highly polymorphic, but the pattern of polymorphism differed from that in humans. The TBP cRRY(i) displays both similarities with and differences from the previously described RRY(i) in the coding sequence of the androgen receptor. The data suggest how simple tandem repeats could evolve from cryptic repeats. 18 refs., 3 figs., 6 tabs.

According to Bragg{close_quote}s rule the stopping cross section {var_epsilon} of a mixture of nonreacting gases should be the weighted average of the stopping cross sections of its constituents. Experimentally we find {var_epsilon} to exceed the Bragg value by more than 50{percent}.

We have characterized the charge, energy, emittance and bunch length of the witness beam over the last several months.

The bunch length was measured by imaging Cherenkov light from a quartz plate to a Hamamatsu streak camera with 2 psec resolution. A beam energy of 3.9 MeV was measured with a 6 inch round pole spectrometer while a beam charge was measured with both an ICT and a Faraday Cup. Although the gun will normally be run at 100 pC it has produced charges from 10 pC to 4 nC. All results of the measurements to date are presented here. {copyright} {ital 1997 American Institute of Physics.}

    The author discusses the frustrations of the international community in dealing with North Korea after negotiation of the Nuclear Non-proliferation treaty. In the past, the international community has not been well prepared to deal with the North Korean obstinacy. It has repeatedly misjudged North Korean goals, South Korean Interests, and Japanese reactions. A new approach is proposed for the long run, that avoids coercion or appeasement. Economic incentives are suggested as the means to bring about changes in North Korean attitudes that will ultimately foster the desire for maintaining economic stability and well being rather than warlike independence. China and the former Soviet Union are not considered supportive of a warlike posture in North Korean but are making economic overtures to South Korea themselves. If the economic approach proves successful, it will enhance the chances of Korean unification by peaceful means and under democratic rule because time is on the side of democracy. In the long run nonproliferation will be achieved through unification.

    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 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}

    Within many large government reservations are many sites that are potentially contaminated from various uses such as experiments, material storage, or material processes. There also exist many smaller areas that, by proximity to contaminated sites, or due to work contracts, are likely to be contaminated. The party responsible for such sites must evaluate if remediation is required, based on current guidelines and future uses. The Departments of Defense and Energy have many sites and properties that are suspected of being contaminated or associated with operations that could cause contamination. In some cases the contaminants may have been adequately cleaned up, then decayed away, biodegraded, or dispersed to a nondetectable level. The decision to remove these sites from any further consideration of remediation or control must be based on historical data, potential contaminants, current analytical data, future uses, and the cost associated with managing the sites. This paper deals with the methodology for evaluating small sites and gives some case studies.

    Just when the power generation industry was stabilizing along came mega government regulations and changing economic conditions that threw a monkey wrench into the works. Although improved inventory practices have helped solve some coal problems, other still remain. The Clean Air Act has resulted in fuel switching, blending, equipment changes, and other factors, all contributing to power plant personnel grey hair. Then along came Just-In-Time inventory practices. Not only is the plant required to make all these changes to meet regulatory requirements, but reduce the quantity of fuel in inventory to unheard of low levels. Why is it so difficult to precisely account for coal in inventory? After all, inventory is a simple matter of accurately measuring the coal coming in to the plant, measuring the coal used by the plant, and conducting an accurate physical inventory to measure the remaining coal. Add to this, a major coal inventory reduction policy, when base maps are not maintained or updated and are, therefore, not likely to be accurate. Some coal may have been stored below the prevailing water table, rendering the coal unusable. Weather conditions, such as major ice storms can render much of the coal unburnable. Unless accounted for, these things reduce the perceived amount of coal in inventory. This presentation will address these issues to assist in preventing potential unscheduled plant shut down and the need to purchase unscheduled blocks of emergency power. Just-In-Time Inventory isn`t as straightforward as first meets the eye.

    During the past thirty years research using high magnetic fields has technically evolved in the manner, but not the magnitude, of the so-called big science areas of particle physics, plasma physics, neutron scattering, synchrotron light scattering, and astronomy. Starting from the laboratories of individual researchers it moved to a few larger universities, then to centralized national facilities with research and maintenance staffs, and, finally, to joint international ventures to build unique facilities, as illustrated by the subject of this conference. To better understand the nature of this type of research and its societal justification it is helpful to compare it, in general terms, with the aforementioned big-science fields. High magnetic field research differs from particle physics, plasma physics, and astronomy in three respects: (1) It is generic research that cuts across a wide range of scientific disciplines in physics, chemistry, biology, medicine, and engineering; (2) It studies materials and processes that are relevant for a variety of technological applications and it gives insight into biological processes; (3) It has produced, at least, comparably significant results with incomparably smaller resources. Unlike neutron and synchrotron light scattering, which probe matter, high magnetic fields change the thermodynamic state of matter. This change of state is fundamental and independent of other state variables, such as pressure and temperature. After the magnetic field is applied, various techniques are then used to study the new state.

    Deep-water carbonate channel reservoirs form important oil reservoirs along the toe of the Eastern Shelf of the Permian basin in west Texas. In northwestern Glasscock County, these `Wolfcamp` reservoirs are Leonardian (Early Permian) in age and define high-energy channels incised into surrounding carbonate detritus and basinal shale. Porous grain-flow material filling these channels, along with encasing detritus, was derived from the shallow shelf located six miles to the east. Reservoirs are in packstone and grainstone facies and have significant interparticle and moldic porosity. Relevant exploration began in the 1960s, but expanded slowly thereafter due to lack of success caused by complex patterns of channel occurrence. Results of a three-dimensional (3-D) seismic survey conducted in 1990 have greatly enhanced the identification and mapping of productive channels in the Powell Ranch field complex. Wells in this complex are capable of flowing 400-1200 bbl of oil per day, and have reserves ranging from 0.2 to 1.3 MBO. The new 3-D data have improved the relevant geologic model and dramatically increased rates of drilling success. Application of such data to this setting offers a potential model for other parts of the Permian basin.

    It is shown that the Regge-Teitelboim criterion for fixing the unique boundary contribution to the Hamiltonian compatible with free boundary conditions should be modified if the Poisson structure is noncanonical. The new criterion requires cancellation of boundary contributions to the Hamiltonian equations of motion. At the same time, boundary contributions to the variation of the Hamiltonian are allowed. The Ashtekar formalism for gravity and hydrodynamics of the ideal fluid with a free surface in the Clebsch variables is treated as an example. {copyright} {ital 1997} {ital The American Physical Society}

  19. Implications of a {open_quotes}cross-rolled{close_quotes} yield surface approximation on deep drawing

    SciTech Connect

    Logan, R.W.

    1996-03-01

    During deep-drawing, two issues manifest themselves that are due to normal and planar anisotropy in the sheet. These are a dependence of the Limiting Draw Ratio (LDR) on the average thinning ratio (R-value), and a dependence of ear formation and thinning around the circumference on the variation of R-value in the plane of the sheet. The quadratic (1948 Hill) yield surface has been applied to these issues and it has been demonstrated that there are numerous higher exponent yield criteria that may more closely duplicate experimental trends. These predict varying degrees of R-value dependencies of uniaxial yields and strength ratios in multiaxial loading paths. The result of this is that there are sometimes subtle and sometimes substantial differences in the predictions of the various yield surfaces on deep drawing regarding LDR and earing. Additional differences arise due to the way the shear term (45-degree yield) and the 0-degree vs. 90-degree strengths are treated in each criterion. These dependencies (in-plane strengths generated by the yield surfaces) are shown to affect the results of both LDR and earing during cupping. In particular, the 1979 Hosford and 1989 Barlat (Tricomponent) criteria, although identical for the normal anisotropy (planar isotropy) case, are strikingly different for cases where there are differences at 45 degrees and 90 degrees from the rolling direction.

    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.

    A major new coalbed gas play with as many as 1,000 wells already proposed is being developed in the Upper Cretaceous Ferron Sandstone of central Utah. The Ferron consists of a vertically stacked sequence of as many as seven fluvial-deltaic sandstones and laterally equivalent interdistributary coal swamp units. A new total-net-coal isopach map for the Ferron, compiled from the review of hundreds of well records, shows the greatest accumulation of coal generally occurs in a 6-to 10-mile-wide band, or fairway, directly to the west (landward) of the fluvial-deltaic sandstones. This fairway can be traced a distance of at least 80 miles, heading southwest from the vicinity of Price to the southeast corner of Sevier County. The fairway is interrupted roughly every 8-to-12 miles along its length by deltaic, distributary-channel systems. Well samples of Ferron coal were examined microscopically to determine vitrinite reflectance and maturity level. Near-surface coals, on the east side of the fairway, have vitrinite reflectance measurements as low as 0.5 percent. Reflectance values increase to the west, reaching a maximum of 0.71 percent. The maturity of coals with vitrinite reflectance readings between 0.5 and 0.71 percent is the early stage in which thermogenic methane generation begins. Examination of drill-hole data also shows that the coal fairway exists at shallow to moderate depths, ranging from surface exposures to 8,000 feet deep.

    Cloud seeding programs are providing some hydro producers with a way of increasing their water reserves on short notice and with relatively low cost. The fundamental formula has been known for half a century: clouds plus cold plus solid particles equal precipitation. What was not certain until more recently is how that relationship could be effectively used to alter the weather in positive ways. Research and practical experience now show that cloud seeding -- adding tiny solid particles to the right clouds at the right temperature -- works. More pertinent, evidence is mounting that hydropower producers can use well-designed, carefully times seeding programs to increase the amount of water available to their systems and thus enhance electricity generation. Cloud seeding has several advantages as a tool to augment hydroelectric production. Seeding programs typically require no capital investment by the utility or other power producer, and can be started and stopped on relatively short notice. Operating costs usually are less than $10 per acre-foot of additional streamflow. More broadly, the additional water produced for hydro generation has the environmental and community relations benefits of being reusable and less expensive than thermal power alternatives. There also normally are the additional benefits of increased water supplies for other users.

    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.

    For more than two decades, programs and policies have sought to encourage the participation of women, minorities, and persons with disabilities in science and engineering careers. However, these groups continue to be underrepresented and underemployed in these fields. This paper focuses on a discussion of models for programs, policies, and services designed to recruit and retain underrepresented groups in science and engineering careers at the precollege, college, graduate, and faculty levels. From the perspective of several recent reports and studies, it examines: (1) the specific program models currently being employed for particular underrepresented groups; (2) remaining gaps in programs, services, and policies designed to recruit and retain these groups; and (3) what program evaluation suggests about the effectiveness of different program models.

    Researchers in the Netherlands are on the track of a genetic mutation in a large Dutch family that may cause periodic outbursts of aggression in its possessors. Han G. Brunner and his colleagues at Univ. Hospital in Nijmegen report evidence suggesting that a mutation in the gene for monoamine oxidase A (MAOA) may underlie the aggressive and sometimes violent behavior displayed by certain males in this family. A linkage between MAOA gene defect and behavioral problems would make biological sense because the enzyme encoded by the gene helps break down several neurotransmitters that might, if their concentrations build up abnormally, cause a person to respond excessively-and at times even violently-to stress. If this original report is borne out by further work, it would be the first time that a specific gene defect has been found to predispose its bearers to aggressive behavior. Using markers for the X chromosome, Brunner and his colleagues identified the MAO gene region as the likely site for the diseased gene.

Rudenjak, while working for an independent contractor at the Oyster Creek Nuclear Power Plant, received a 3.335 Rem dose of whole-body radiation over a 4-month period in 1980. In 1988, Rudenjak died of acute leukemia and his widow sued the power company. The utility filed a motion to dismiss based on the statutory employer defense, which was granted by the court; excepts of the court`s decision are included in the article. A similar suit in California is also described; the implication is that legal precedent has been established in California and New Jersey to prevent employees of independent contractors from suing utilities.

    1995-06-01

    The great increase in world population in the coming century will result in a human crisis of worldwide proportions. A new concept for describing and proposing solutions to this crisis, called the Trilemma, is described by the authors. To feed large and growing populations, humankind is now being forced to make the difficult choice between producing sufficient food for the world population and preserving the environment, or generating economic growth, requiring the consumption of energy and natural resources. These difficult choices present the Trilemma, a new concept that is composed of three dimensions: economic growth, resources such as energy and food, and the environment. None of these three dimensions can be optimized individually as they are mutually interdependent. This paper describes a possible world energy condition in the 21st century. Three scenarios of this energy consumption are presented and compared with the possible energy supply at that time. This supply is estimated from the extrapolation of the renewable energy development of the past and the possible fossil fuel supply. The comparison of the energy supply and the energy consumption indicates that the annual rate of economic growth in the developed region would be only 1% if the gross national product (GNP) per capita of the developing region increases gradually from 1/26 of the GNP of the developed regions in 1990, to 1/10 in 2020, and finally to 1/3 in 2100. Another possibility is that if the GNP per capita of the developing region remains 1/26 of the GNP of the developed regions between 1990 and 2100, the economic growth rate in the developed region could be as large as 3%. In the latter case, an energy shortage would develop in the middle of the 21st century, even if the fast breeder reactor were fully operational by the year 2030. Energy technological developments in Japan are also described as a part of the possible countermeasures against the Trilemma. 9 refs., 11 figs.

It took 26 years to prove that Pauli`s particle even exits-a feat for which Frederick Reines of the University of California (UC), Irvine, won the Nobel Prize last month. Soon, however, physicists will be capturing neutrinos in unprecedented numbers in a 50,000-metric-ton tank that will fill with water starting next month.

    One of the principal advantages of Biodiesel is its environmental compatibility. Its biodegradability and reduced toxicity make it an ideal candidate fuel for environmentally sensitive areas. Biodiesel has potential as a fuel for equipment operating in or near waterways, sensitive wildlife habitat and other environmentally sensitive areas. The national park system has a mandate to maintain the environment in the areas they supervise. Use of Biodiesel could be one more tool in achieving that goal. This paper is a progress report of a joint project between the University of Idaho, The Montana Department of Natural Resources and Conservation, Wyoming Department of Energy, the PNW and Alaska Regional Bioenergy Program, Chrysler Corporation and the National Park Service to fuel an on-road vehicle for service in Yellowstone National Park. A 5.9L Cummins powered Dodge pickup, supplied by Dodge Truck, is being operated by NPS with fuel produced by the University of Idaho. Tests include regular dynamometer testing, emissions tests, injector coking analysis, oil analysis, detailed operational records and fuel characterization tests according to the ASAE proposed Engineering Practice for Testing of Fuels from Biological Materials, X552.

    Engineered and natural barriers can limit, and possibly eliminate, radionuclide migration to the far field and accessible environment over geologic time scales. Nevertheless, proper deployment of replaceable monitoring systems can inform future operators (1) if radionuclide release or migration occurs, (2) its general location and migration path, and (3) its magnitude and rate of migration. If necessary, corrective action can be taken. The time scale for these monitoring and detector-replacement activities is assumed to be from 10`s to possibly 1000`s of years. Detector placement would be in a phased approach depending upon the potential loss paths identified in the overall site characterization and possibly other investigations.

    Composites of fullerene C{sub 60} with conjugated polymers (CP) like polyalkylthiophene (PAT) and polyphenylene vinylene derivative (OO-PPV) have earlier demonstrated intensive charge transfer upon photoexcitation. Doping of CP/C{sub 60} composites by A metal vapors (A=K,Rb) is aimed at C{sub 60} induced SC, in which electrons of CP chains may participate in SC pairing, induced via hybridization with C{sub 60} molecules. We have found an SC phase experimentally both in PAT. (C{sub 60}) {sub y}K{sub x} and OO.PPV (C{sub 60}){sub y}K{sub x} by a sensitive method of low field microwave absorption (LFMA), and proved by SQUID. The SCT{sub c} ranges from 12 to 17 K, depending on y and x. This SC phase shows a granular behavior in LFMA, and thus originates from SC A{sub 3}C{sub 60} clusters weakly linked by Josephson junctions. True C{sub 60} induced SC might be masked by granular A{sub 3}C{sub 60}. Anomalous LFMA and paramagnetic Meissner effects observed in SQUID, indicate the existence of Josephson {pi}-junctions. CP is apparently involved in SC via spin carrying polarons P in CP chains, which play a role of {pi}-junctions. Strategies for further search of C{sub 60} induced SC are discussed.

    A review of hydrogen combustion research at Kurchatov Institute is presented. Criterion for spontaneous detonation onset possibility and its application to severe accidents in a nuclear power plant is discussed. Theoretical and experimental results on spontaneous detonation onset conditions are summarized. Three series of large scale turbulent jet initiation experiments have been carried out in KOPER facility (50 m{sup 3} and 150 m{sup 3}). Series of jet initiation experiments in initially confined H{sub 2} - air mixtures have been carried out in KOPER facility (20-46 m{sup 3}). Turbulent deflagration/DDT experiments were carried out in large scale confined volume of 480 m{sup 3} in RUT facility. Results showed, that the characteristic volume size should be used for conservative estimates in accident analysis. Series of experiments on detonation transition from one mixture to another of lower sensitivity has been carried in DRIVER facility. The experiments were aimed on the estimation of the minimum size of a detonation kernel. The received results are in a good agreement with the 7 cell width criterion. Results of combined hydrogen injection/ignition experiments are presented. The experiments are aimed on the investigation of possible consequences of deliberate ignition at dynamic conditions. Analysis of the experimental data showed applicability of 7 cell width criterion to dynamic conditions. The sum of the results on the scaling of spontaneous detonations is discussed in connection with the strategy of hydrogen mitigation at severe accidents.

    1994-11-01

    Portability, efficiency, and ease of coding are all important considerations in choosing the programming model for a scalable parallel application. The message-passing programming model is widely used because of its portability, yet some applications are too complex to code in it while also trying to maintain a balanced computation load and avoid redundant computations. The shared-memory programming model simplifies coding, but it is not portable and often provides little control over interprocessor data transfer costs. This paper describes a new approach, called Global Arrays (GA), that combines the better features of both other models, leading to both simple coding and efficient execution. The key concept of GA is that it provides a portable interface through which each process in a MIMD parallel program can asynchronously access logical blocks of physically distributed matrices, with no need for explicit cooperation by other processes. The authors have implemented GA libraries on a variety of computer systems, including the Intel DELTA and Paragon, the IBM SP-1 (all message-passers), the Kendall Square KSR-2 (a nonuniform access shared-memory machine), and networks of Unix workstations. They discuss the design and implementation of these libraries, report their performance, illustrate the use of GA in the context of computational chemistry applications, and describe the use of a GA performance visualization tool.

    The past decades have seen a tremendous development in nuclear, middle, and high energy physics. This advance was in a great part promoted by the availability of newer and more powerful instruments. Over time, these instruments grew in size as well as in sophistication and precision. Nearly all these devices had one fundamental thing in common - magnetic fields produced with currents and iron. The precision demanded by the new experiments and machines did bring the magnet technology to new frontiers requiring the utmost in the accuracy of magnetic fields. The complex properties of the iron challenged innumerable physicists in the attempt to force the magnetic fields into the desired shape. Experience and analytical insight were the pillars for coping with those problems and only few mastered the skills and were in addition able to communicate their intricate knowledge. It was a fortuitous situation that the authors got to know Klaus Halbach who belonged to those few and who shared his knowledge contributing thus largely to the successful completion of two large instruments that were built at the Forschungszentrum Juelich, KFA, for nuclear and middle energy physics. In one case the efforts went to the large spectrometer named BIG KARL whose design phase started in the early 70`s. In the second case the work started in the early 80`s with the task to build a high precision 2.5 GeV proton accelerator for cooled stored and extracted beams known as COSY-Juelich.

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.

    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.

    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.

    The authors comment on the previous paper by Goertz, et. al., which they had refereed prior to the authors deaths. They question a number of correlations claimed in that paper. In particular the auroral electrojet index observed, and that infered from ISEE 3 measurements. They also point out possible problems with a cutoff time filter applied to data used in the study. This filter would remove high frequency variations in the electrojet observations. Goertz, et. al. obtain equations for the ionospheric electric field which mimic the field across a resistor in an inductive circuit driven by a time varying voltage. The authors argue that their success in making predictions based on these equations is a consequence of several factors which they did not fully explore.

    The authors have analyzed three de novo chromosome 16 rearrangements-two with a 16p+ chromosome and one a 16q+-none of which could be fully characterized by conventional cytogenetics. In each case, flow karyotypes have been produced, and the aberrant chromosome has been isolated by flow sorting. The origin of the additional material has been ascertained by amplifying and labeling the DNA of the abnormal chromosome by degenerate-oligonucleotide-primer-PCR and hybridizing it in situ to normal metaphase spreads (reverse chromosome painting). Both 16p+ chromosomes contain more than 30 Mb of DNA from the short arm of chromosome 9 (9p21.2-pter), while the 16q+ contains approximately 9 Mb of DNA from 2q37. The breakpoints on chromosome 16 have been localized in each case; the two breakpoints on the short arm are at different points within the terminal band, 16p13.3. The breakpoint on the long arm of chromosome 16 is very close to (within 230 kb of) the 16q telomere. Determination of the regions of monosomy and trisomy allowed the observed phenotypes to be compared with other reported cases involving aneuploidy for these regions. 41 refs., 4 figs.

    Gravity anomalies, records from historical oil wells, and new organic geochemical results indicate the presence of a concealed sedimentary basin of probable Miocene age beneath a densely populated part of the Santa Clara Valley. A prominent isostatic gravity low extends about 35 km from Palo Alto to near Los Gatos and reflects an asymmetric, northwest-trending sedimentary basin comprising low-density strata that rest on higher-density rocks of the Franciscan Complex. Both gravity and well data show that the low-density rocks thin gradually to the northeast over a distance of about 10 km. The thickest basin fill (about 3 km) occurs along the basin's steep southwestern margin, which evidently is controlled by northwest-trending, southwest-dipping reverse and thrust faults of the seismically active Berrocal, Shannon, and Monte Vista fault systems. Near surface traces of these faults in Los Gatos, at least 12 wells were drilled between 1891 and 1929 to total depths as great as 840 m. No lithologic or paleontologic samples are available from the wells, but drillers logs indicate thick intervals of brown shale and sandstone resembling nearby outcrops of the Miocene Monterey Formation. Small amounts of oil and gas were encountered in several wells, but no commercial production was established. Oil from a well in Los Gatos is highly biodegraded, contains biomarkers commonly found in oils derived from the Monterey Formation, and yields a stable carbon isotopic ([delta][sup 13]C[sub PDB]) composition of -23.32[per thousand], suggesting derivation from a Miocene source. Oil in mercury ore from the nearby New Almaden mine is slightly biodegraded, thermally altered, and shows a [delta][sup 13]C PDB value of -24.70[per thousand], indicating a source different from that of the Los Gatos oil and perhaps of Miocene or Cretaceous age.

    Oil spill contingency planning and response is an extremely complex and challenging cross-disciplinary activity. It combines a wide range of activities under emergency response conditions that include the nature of the material spilled, local environmental conditions, sensitivity of impacted natural resources, and selection and effectiveness of response/cleanup technologies. This also emcompasses emergency mobilization, marine operations and effectiveness of operations, air surveillance, remote sensing, on-site and regional spill trajectory, human protection, safety assessments, oily waste minimization, handling and disposal, and education and training. Effective oil spill planning and response today also requires a large amount of available data and information and the ability to rapidly process and manage this information. In addition, the decision-making process must integrate all of this information on a sound scientific and engineering basis, which is now possible with the technology windows-of-opportunity. This new concept integrates scientific and engineering data and information, which together provide a common foundation for the development of a rapid and cost-effective tool as an operational instrument for oil spill contingency planning and spill response. It is intended to be used by state and federal agencies, response planners, cleanup organizations, insurance companies, tanker owners, and oil transporters.

    We describe conventional and high-resolution transmission electron microscopy (HRTEM) characterization of the microstructure of sputtered NiFe/Cu giant magnetoresistance spin valves (Cu/FeMn/NiFe/Cu/NiFe) sandwiched between thick Nb contact layers. Six spin valves, sputtered at different temperatures, three with thin (3 nm) and three with thick (24 and 30 nm) NiFe layers, were studied. All of the spin-valve layers were smooth and continuous, consisting of columnar grains generally 20{endash}90 nm wide. In most cases, the grains had grown epitaxially from the bottom contact, through the entire multilayer, to the top contact layer. The columnar grains grew on the closest-packed planes (i.e., {l_brace}110{r_brace} planes for bcc Nb and {l_brace}111{r_brace} planes for fcc Cu, FeMn, and NiFe spin-valve components). This epitaxial growth yields an apparent Kurdjumov{endash}Sachs {l_brace}111{r_brace}{sub fcc}{parallel}{l_brace}110{r_brace}{sub bcc}; {l_angle}110{r_angle}{sub fcc}{parallel}{l_angle}111{r_angle}{sub bcc} orientation relationship. However, HRTEM imaging supported by fast Fourier transform analysis reveals that in some of the columnar grains the Cu, FeMn, and NiFe layers take up a nonequilibrium bcc structure. In these cases, the bcc Cu, FeMn, and NiFe layers grow on {l_brace}110{r_brace} planes and are epitaxial with the Nb contacts for the individual grain columns. While bcc Cu has been observed elsewhere, the length scale of the nonequilibrium bcc phases reported here is an order of magnitude greater than previously observed. {copyright} {ital 1999 American Institute of Physics.}

    Disposal of Department of Energy (DOE) radioactive waste into repositories such as the Waste Isolation Pilot Plant (WIPP) and the Nevada Test Site (NTS) requires characterization to ensure regulatory and transportation requirements are met. Characterization is also used to collect information regarding chemistry of the waste for processing concerns. The range of characterization typically includes radio nuclide activity, RCRA metals and organic compounds, process metals, and risk assessment. Recent addition of an inductively coupled plasma quadrupole mass spectrometer in a radioactive contaminated laboratory at the Oak Ridge National Laboratory (ORNL) has provided cost savings, time savings, reduced personnel exposure to radiation, and in some cases, improved accuracy over the traditional techniques for radionuclides, risk assessment and metals analysis. Application of ICP-MS to ORNL waste tank characterization has also provided the opportunity to estimate never-before-measured radionuclides and metals without increased cost. Data from analyses of ORNL waste tank sludges and supernates indicate the benefit of using this technique over counting techniques and Thermal Ionization Mass Spectrometry (TIMS) for analysis of fission products and U isotopics as well as the ability to estimate certain radionuclides and metals for the first time in these tanks.

    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.

    Microsensors do not have the selectivity to chemical species available in large laboratory instruments. This project employed arrays of catalytically gated silicon microsensors with different catalysts to create data streams which can be analyzed by pattern recognition programs. One of the most significant accomplishments of the program was the demonstration of that mixtures of H{sub 2} with the oxidants NO{sub x} and O{sub 2} could distinguished from one another by the use of different catalytic metals on the Sandia Robust Hydrogen (SRH) sensors and the newly developed pattern recognition algorithm. This sensor system could be used to identify explosive gas mixtures and analyze exhaust streams for pollution control.

    Trace quantities of plutonium are observed in the environment all over the world, and include both man-made {sup 238-242}Pu and natural {sup 239}Pu in uranium ores. Typical concentrations range from 10{sup {minus}14} g Pu/g sample up to 10{sup {minus}12} g Pu/g in pitchblende. We have determined some upper concentration limits for the plutonium in samples from KTB (Kontinentales Tiefbohrprogramm, Germany) which are in the range of 10{sup {minus}15} down to 3{center_dot}10{sup {minus}17} g Pu/g sample. In addition, we have investigated one sample of Hawaiian lava, with a limit of 5{center_dot}10{sup {minus}15}. We could not confirm previous reports on the observation of plutonium in some Pacific Lavas, nor do our results show any evidence for cold fusion neutrons producing plutonium in fluids of great depth in the crust.

    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.

    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.

    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.

    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 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

    At the end of the 20th century, access to information provided by the World Wide Web (WWW) is changing as never before. The fast availability of current medical literature and the availability of tools for easy access to information, as well as for the easy production of information, have confronted research physicians, scholars, and students with new kinds of problems, many of which concern us personally. Quality control, difficulty establishing basic citation components, lack of standard guidelines for citing, as well as the short lifetime of Internet addresses concern us deeply. Some of these problems could be solved by the concept of an Online-Library of Medicine presented in the following paper. Since, however, at the present time there are no good answers to the problems regarding citing Internet-based sources, a Web surfer must keep in his or her mind the motto caveat lector (let the reader beware) - or, rather, in the spirit of our time: click c@refully before you cite.

  3. Julio Cortzar quotes on normal and abnormal movements: magical realism or reality?

    PubMed

    Merello, Marcelo

    2006-08-01

    Together with Mario Vargas Llosa and Gabriel Garca Mrquez, Julio Cortzar was one of the most representative authors of the Latin American magical realism genre. Within his extensive body of work, many descriptions of characters suffering physical disabilities, as well as situations suggesting such medical conditions, can be extracted. In this review, two short stories by Cortzar are presented. In the first one, the main character could easily be a man suffering from corticobasal degeneration; in the second, an old woman with symptoms suggestive of progressive supranuclear palsy is clearly depicted. Despite the fact that one of the main ingredients in Cortzar's magical realism is fiction, cases described here fit real medical conditions quite well, making it hard to believe that they represent purely fantastic descriptions rather than the product of Cortzar's inquisitive observation and the description of real patients.

    An interactive color graphical user interface, with animation, has been developed to port SnapPea to the OS/2 Warp Personal Computer (IBM type PC) platform. This fulfills the interest to use an Intel microprocessor based computer to study the geometry and topology of three-dimensional hyperbolic manifolds and to perform mathematical computations with them. Hitherto the program was available only on Macintosh computers. The OS/2 operating system kernel program has for many years supported long file names, had multithreading, pre-emptive multitasking an built in crash-protection. There is also a full 32-bit graphics engine. Already, there is much interest in this product. The software is expected soon to be available to mathematicians around the world, to use in their research. A demonstration was given at the conference.

    Families in which a balanced translocation has been transmitted from a normal parent to a child with a phenotypic abnormality have been a longstanding puzzle for human geneticists. A child with phenotypic features of the 9p- syndrome, including metopic craniosynostosis, small ears, abdominal wall defect, and mental retardation, was found to have a cytogenetically balanced 3;9 translocation, with breakpoints at 3p11 and 9p23, inherited from his normal father. He also exhibited marked hypopigmentation of hair and skin. Analysis with a cDNA probe from the TYRP1 (tyrosinase-related protein 1) gene in 9p23 showed heterozygous deletion in the child but in neither parent. This submicroscopic deletion also included loci D9S157, D9S274, D9S268, and D9S267. FISH analysis of the proband`s father indicated the 9p23 loci deleted in his son were present on neither the der(3) nor the der(9) translocation product, but had been inserted into the long arm of chromosome 8. Therefore, the apparent deletion of these loci in the proband was the result of meiotic segregation of the father`s 3;9 translocation chromosomes together with his normal chromosome 8. Neither the deletion from the translocation chromosomes nor the insertion into 8q was detectable by standard chromosome banding techniques. The proband`s sister exhibited speech delay, mild facial dysmorphism, and renal malformation, and her karyotype was 46,XX. Molecular analysis of this sister showed 3 copies of 9p23 sequences, indicating that she had inherited normal chromosomes 3 and 9 from her father as well as the chromosome 8 with the insertion from 9p23. This analysis illustrates a new mechanism to explain cases of phenotypic discordance in familial balanced translocations: submicroscopic deletion of material from the translocation breakpoint and insertion into a third chromosome in the balanced parent, with meiotic segregation leading to loss of the inserted material in the child.

  15. 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

    Krakowski, R.A.

    1997-08-24

    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.

    Minimizing resonant, static n = 1 error field with a phase steerable correction coil the C-coil, in DIII-D allows avoidance of disruptive locked modes. Alternatiely, increasing n = 1 error field in rapidly rotating plasmas can induce magnetic braking of rotation without locking for the study of the role of rotation on stability. Small toroidally asymmetric m = 2, n = 1 static field errors are of concern for the design of next-generation devices and for the operation of existing tokamaks. In low density ohmic plasmas for example, the torque of a small resonant error at the q = 2 surface can overcome the plasma inertial and/or viscous forces, stop the rotation and produce a large island which can cause disruption.

    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.

    The synthesis, characterization, and vis-NIR-IR vapochromic/spectroscopic studies are reported for isocyanide compounds of the form [Pt(arylisocyanide){sub 4}][Pt(CN){sub 4}] (where arylisocyanide = p-CNC{sub 6}H{sub 4}C{sub n}H{sub 2n+1}; n = 1, 6, 10, 12, 14). The dark blue, solid materials change color in the NIR (near-infrared) spectral region upon exposure to the ambient room-temperature vapor pressure of volatile organic compounds (VOCs). All the spectroscopic data suggest that the VOC penetrates the solid and interacts with the linear chain chromophore to cause the spectral shifts in the vis-NIR-IR spectral regions. The vapochromic shifts are suggested to be due to diole-dipole and/or H-bonding interactions between the Pt(CN){sub 4}{sup 2-} anion and polar VOCs. For nonpolar VOCs, lypophilic interactions between the VOC and the isocyanide ligands that cause no change in the {nu}-(CN) stretching region must cause the NIR vapochromism observed. The absence of a vapochromic response for water vapor is suggested to arise from hydrophobic blocking of the water at the solid/gas interface. 21 refs., 4 figs., 3 tabs.

The deviations from the ideal fluorite structure were examined and an apparent discontinuity observed for the metal atom shift allowed by Ia3 symmetry. Previously suggested metal atom ordering was not observed in the C-type structure. Models have been proposed to understand the limiting compositions of the fluorite-type and C-type solid solutions.

    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.

    The recommendation to keep exposures to ionizing radiation {open_quotes}as low as reasonably achievable{close_quotes} (ALARA) has been a long-standing component of radiation safety programs. This recommendation is based on the assumption that there is no dose threshold below which harmful biological effects will not occur. With this assumption, it logically follows that there is no {open_quotes}safe{close_quotes} level of exposure and that any exposure, no matter how low, carries with it some risk of harm. This presumption was a departure from a previously established principle in public health that could be paraphrased {open_quotes}the dose makes the poison,{close_quotes} which held that high-dose effects of harmful agents are not necessarily indicative of low-dose effects. The concept of further minimizing radiation exposures to levels well below specified dose limits originated in the 1950s with the International Commission on Radiological Protection (ICRP) recommendation that doses be kept {open_quotes}as low as possible{close_quotes} (ALAP), In 1959, ICRP replaced {open_quotes}possible{close_quotes} with {open_quotes}practicable,{close_quotes} and in 1973, ALAP was changed to ALARA to convey ICRPs intent to achieve dose minimization with {open_quotes}economic and social considerations being taken into account.{close_quotes} To implement this guidance, ICRP recommended application of cost-benefit analysis to balance economic costs against benefits of dose reduction.

    {open_quotes}Standard{close_quotes} approaches such as regression analysis, Fourier analysis, Box-Jenkins procedure, et al., which handle a data series as a whole, are not useful for very large data sets for at least two reasons. First, even with computer hardware available today, including parallel processors and storage devices, there are no effective means for manipulating and analyzing gigabyte, or larger, data files. Second, in general it can not be assumed that a very large data set is {open_quotes}stable{close_quotes} by the usual measures, like homogeneity, stationarity, and ergodicity, that standard analysis techniques require. Both reasons dictate the necessity to use {open_quotes}local{close_quotes} data analysis methods whereby the data is segmented and ordered, where order leads to a sense of {open_quotes}neighbor,{close_quotes} and then analyzed segment by segment. The idea of local data analysis is central to the study reported here.

    We have characterized two intragenic polymorphisms in the neurofibromatosis type 1 (NF1) gene by direct sequencing of PCR products. The variants for these polymorphisms were initially detected on Hydrolink gels. One of the polymorphisms involves a G to A transition in intron 41 at the 28th base upstream of exon 42 with an observed {open_quote}G{close_quote}/{open_quote}A{close_quote} heterozygosity of 0.42. The other polymorphism is a T to C transition in intron 16 at the 16th base upstream of exon 17 with an observed {open_quote}T{close_quote}/{open_quote}C{close_quote} heterozygosity of 0.09. In combination with other documented polymorphisms in the NF1 gene, these variants should assist in genetic analysis of NF1 families. 24 refs., 3 figs.

In fact, our article described this idea as a {open_quotes}commonly invoked assumption{close_quotes}. With regard to the R148W substitution, the Reichardt et al. article states that {open_quotes}the mutated arginine is not conserved{hor_ellipsis}. However, this mutation results in an unstable polypeptide and, therefore, the mutated arginine 148 is probably not enzymatically important.{close_quotes} We certainly apologize for any misunderstandings resulting from our interpretation, or possible misinterpretation of these words. 9 refs.

Our various decoration rules encompass cases with face-centered icosahedral (FCI) symmetry and with simple icosahedral (SI) symmetry, and include additional variations in the occupancy and/or chemistry of certain site types. Each decoration was applied to 11 distinct periodic approximants of the tiling. We found that (i) the relaxed atomic positions of each site type can be closely approximated by fixed positions on each tile type, even though the environments (beyond the first neighbor) are inequivalent. (ii) Models with simple icosahedral (SI) space-group symmetry were better than those with face-centered icosahedral (FCI) space-group symmetry. (iii) {open_quote}{open_quote}Loose{close_quote}{close_quote} decorations, containing voids almost large enough for an atom, were better than the {open_quote}{open_quote}dense{close_quote}{close_quote} decorations which were suggested by packing considerations. (iv) Our results depended on using the realistic potentials; {ital short}-range potentials favor the {open_quote}{open_quote}dense{close_quote}{close_quote} structures, and many details depend on the second or further oscillations in the potentials. (v) For our best model, there is relatively little variation of the energy when tiles are rearranged, i.e., a {ital random}-{ital tiling} {ital model} is a good zero-order description of the system. {copyright} {ital 1996 The American Physical Society.}

    Electrical transport in zinc oxide varistors is simulated using two-dimensional Voronoi networks. The networks are assumed to contain randomly distributed grain boundaries of three electrical types: (1) high nonlinearity (i.e., {open_quote}{open_quote}good{close_quote}{close_quote}) junctions; (2) poor nonlinearity (i.e., {open_quote}{open_quote}bad{close_quote}{close_quote}) junctions; and (3) linear with low-resistivity (i.e., ohmic) junctions. These type classifications are those found in experimental measurements. By varying the type concentrations, the simulated current density versus electric field ({ital J}{endash}{ital E}) characteristics can be made to conform to the different experimentally observed characteristics of ZnO varistors. These characteristics include the sharpness of switching at the transition between ohmic and nonlinear {ital J}{endash}{ital E} response (i.e., knee region), as well as the degree of nonlinearity. It is shown that the reduction of the nonlinearity coefficient of bulk varistors, relative to that of isolated grain boundaries, can be explained only by the presence of {open_quote}{open_quote}bad{close_quote}{close_quote} varistor junctions. {copyright} {ital 1996 American Institute of Physics.}

    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.

    The spy novel nightmare scenarios of nuclear smuggling have become reality, and much of the recent news has focused on Germany. But these events must be put in perspective, and a number of apparent {open_quotes}facts{close_quotes} must be examined more carefully. For example, while authorities in Germany have seized weapons-usable material in various incidents that have captured international attention, none of this material is from nuclear weapons or weapons production facilities. Moreover, despite the fact that the number of criminal cases has risen, the quantity of {open_quotes}loose{close_quotes} weapons-usable material is still not significant. Nor are there any indications so far that powerful criminal organizations or buyers from nuclear-ambitious {open_quotes}rogue{close_quotes} states are involved. Rather, the incidents so far involve individuals or small groups of criminals who found that their {open_quotes}buyers{close_quotes} were, more often than not, German security agents working {open_quotes}sting{close_quotes} operations to trap the smugglers and black marketeers or journalists working on a {open_quotes}big story.{close_quotes}

    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

This method accommodates asymmetries in the dynamics of ask and bid quotes after trade-related shocks. The empirical specification is a vector error correction (VEC) model for ask and bid quotes, with the spread as the co-integrating vector, and with an endogenous trading

The Project will also demonstrate the use of modular, {open_quotes}non-grid{close_quotes} or {open_quotes}village{close_quotes} units which can be used throughout the world where geothermal energy is present in remote locations and power is not. The Project was conceived as a 20,000 kw Qualifying Facility, divided into two phases, a 5,000 kw phase one followed by a 15,000 kw phase two. The first phase of the Project now consists of two (2) 3,000 kw plants to generate 6,000 kws.

    The House Transportation and Infrastructure Committee has approved and sent to the House floor a bill to scale back regulations under the Clean Water Act (CWA). Amending clean water legislation has been one of the top items on the Republican regulatory reform agenda. The bill removes federal jurisdiction over stormwater runoff and abandons national standards for pesticide, fertilizer, and other agricultural runoff. The committee okayed the bill despite strong objections from Democrats, some state regulators, and environmental groups. State water pollution regulators say the bill fails to set clear water quality goals, sets protection standards too low, and stretches the use of risk assessment and cost benefit analyses too far.

    The extra-terrestrial scenario of the origin of life suggested by Svante Arrhenius (1) as the {open_quote}panspermia{close_quote} hypothesis was revived by the discovery of a low-temperature quantum limit of a chemical reaction rate caused by the molecular tunneling (2). Entropy factors play no role near absolute zero, and slow molecular tunneling can lead to the exothermic formation of quite complex molecules. Interstellar grains or particles of cometary tails could serve as possible cold seeds of life, with acetic acid, urea and products of their polycondensation as quasi-equilibrium intermediates. Very cold solid environment hinders racemization and stabilizes optical activity under conditions typical for outer space. Neither {open_quote}advantage{close_quote} factors can secure the evolutionary formation of chiral purity of initial prebiotic monomeric medium{emdash}even being temporary achieved it cannot be maintained at subsequent stages of prebiotic evolution because of counteraction of {open_quote}enantioselective pressure{close_quote}.

    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.

    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.

    We show that any rectilinear polygonal subdivision in the plane can be converted into a {open_quotes}guillotine{close_quote} subdivision whose length is at most twice that of the original subdivision. {open_quote}Guillotine{close_quotes} subdivisions have a simple recursive structure that allows one to search for {open_quotes}optimal{close_quotes} such subdivisions in polynomial time, using dynamic programming. In particular, a consequence of our main theorem is a very simple proof that the k-MST problem in the plane has a constant factor polynomial-time approximation algorithm, and the constant factor that we obtain is a substantial improvement over all previous bounds: We obtain a factor of 2 for the L{sub 1} metric, and a factor of 2{radical}2 for the L{sub 2} (Euclidean) metric.

While {open_quotes}gathering{close_quotes} may generally be defined as some physical collection or aggregation activity, its legal definition is crucial under section 1(b) of the Natural Gas Act (NGA) as it effectively describes the limits of commission regulatory authority. In addition, {open_quotes}gathering{close_quotes} as a separately functionalized service of interstate pipeline transportation has significance as it is distinguished as an unbundled service for purposes of pipeline rate design. That is not to say that these two definitions have always been the same. And if they have, it does not mean that they have been subject to the same regulatory treatment. Commencing on May 27, the commission has made a giant step in attempting to rationalize its somewhat disparate efforts in the regulation of gathering.

The exactly soluble D {yields} {infinity} limit, which retains much of the correlation present in the D = 3 solution, provides a zeroth order solution about which a perturbation theory in 1/D is developed.

    Model polydimethylsiloxane networks were prepared by crosslinking vinyl terminated chains with employing hydrosilylation reactions at low temperature. At low temperatures, significant side reactions were found be absent, thereby leading to networks with well defined stoichiometries. These networks were study with regard to their stress-strain isotherms in elongation. The results can be best explained on premises of the more recent molecular theory of Flory and Erman, within limits set by inaccuracies in the determination of the sol fraction and so the structural parameters of the network.

Large customers perceive a possible advantage in contracting for and managing their supplies through the entire pipeline/distributor infrastructure, particularly as an indirect means of cutting LDC margins by paying [open quotes]only for what they use.[close quotes] Producers also see the prospect of cutting LDC margins through [open quotes]competition.[close quotes] Those policymakers and economists that saw efficiency gains in turning pipelines into common carries presumably see the same potential with distributors. And some LDCs may be starting down that path. Is there a certain inevitability to this Will distributors be out of the merchant business in, say, five years Will the homeowner get a bill for transportation from PECO and a bill for gas from Enron Access Maybe. Certainly it is not inevitable. The revolution in telecommunications that gave us competition in long distance largely stopped with the baby Bells. Duly noting the California plan, electric utilities are sellers of commodities - not common carriers, as are water companies. Even the cable companies are exclusive sellers of what they carry. So the experience of other utility industries does not preordain that LDCs transport rather than sell gas. Thus, it is quite possible that the [open quotes]equilibrium[close quotes] for LDC activities pre-636 is the equilibrium post-636. That is, large end users would continue to transport gas on the LDC system while all others would continue to purchase a bundled merchant service from the LDC. But the jury will be out for the foreseeable future.

  14. Toxicity evaluation and hazard review for Rigid Foam

    Archuleta, M.M.; Stocum, W.E.

    1994-02-01

    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.

    It is proposed that quasicrystal structure determination should include the calculation of cohesive energies using realistic potentials. A class of atomic decoration models for {ital i}-AlMn is then presented, adopting the {open_quote}{open_quote}canonical-cell{close_quote}{close_quote} tiling geometry, with {open_quote}{open_quote}Mackay icosahedron{close_quote}{close_quote} clusters placed on all its nodes. The remaining atomic positions are based, as far as possible, on the known structure of {alpha}-AlMnSi. These models guarantee good local packing of the atoms, whose displacements away from {open_quote}{open_quote}ideal{close_quote}{close_quote} positions are specified by only a moderate number of parameters. Certain atomic sites are uncertain as regards their occupancy and/or chemistry; variations of the decoration rules on these sites must be compared, in order to discover the correct one. Our models are well adapted to be relaxed under an effective Hamiltonian to optimize the cohesive energy; we show how the energies found in such relaxations can be used to extract an effective tile-tile Hamiltonian, as would be needed for future studies of phason elasticity and the development of long-range order. In addition, we clarify concepts needed for decoration models in general (in particular, the ways in which elaborate, more realistic decorations may be evolved from simpler ones). We also show that these decoration models are closely related, but not identical, to quasiperiodic structures defined using six-dimensional formalism. {copyright} {ital 1996 The American Physical Society.}

    Considered {open_quotes}paper tigers{close_quotes} by many during their first few years of existence, state and federal right-to-know and hazard communication laws are not only increasingly the subject of enforcement activity, they are eliciting information which will result in increased enforcement of other environmental laws. The growth in popularity of {open_quotes}regulation by information{close_quotes} programs like TRI reflects a fundamental transition in the nature of environmental regulation. For years, source reduction has been a stated top priority for the major federal regulatory programs, but regulators have made little progress toward achieving this goal. Frustrated after years of managing {open_quotes}end-of- the-pipe{close_quotes} programs without any headway toward source reduction, regulators have gravitated toward {open_quotes}right-to-know{close_quotes} regulatory schemes requiring disclosure of the regulated facility`s use of materials and patterns of waste management. Recognizing that {open_quotes}knowledge is power,{close_quotes} regulators cite a number of advantages in adopting such strategies. First, the public availability of reported data provides a strong incentive for companies to eliminate the need to report. Second, compilation of such data invites analysis and comparisons. Data can be evaluated by regulatory program, by environmental media, by industry, by geographic region, and even by individual facility. Third, right-to-know programs conserve scarce regulatory resources by inviting state and local governments, as well as citizen groups, to enforce environmental law. This new decentralized {open_quotes}holistic{close_quotes} approach to regulation, linking information reported under right-to-know laws to pollution prevention requirements and cross-media or facility-wide enforcement initiatives, makes careful attention to this area of law essential.

    Fault seal can arise from reservoir/non-reservoir juxtaposition or by development of fault rock of high entry-pressure. The methodology for evaluating these possibilities uses detailed seismic mapping and well analysis. A {open_quote}first-order{close_quote} seal analysis involves identifying reservoir juxtaposition areas over the fault surface, using the mapped horizons and a refined reservoir stratigraphy defined by isochores at the fault surface. The {open_quote}second-order{close_quote} phase of the analysis assesses whether the sand-sand contacts are likely to support a pressure difference. We define two lithology-dependent attributes {open_quote}Gouge Ratio{close_quote} and {open_quote}Smear Factor{close_quote}. Gouge Ratio is an estimate of the proportion of fine-grained material entrained into the fault gouge from the wall rocks. Smear Factor methods estimate the profile thickness of a ductile shale drawn along the fault zone during faulting. Both of these parameters vary over the fault surface implying that faults cannot simply be designated {open_quote}sealing{close_quote} or {open_quote}non-sealing{close_quote}. An important step in using these parameters is to calibrate them in areas where across-fault pressure differences are explicitly known from wells on both sides of a fault. Our calibration for a number of datasets shows remarkably consistent results despite their diverse settings (e.g. Brent Province, Niger Delta, Columbus Basin). For example, a Shale Gouge Ratio of c. 20% (volume of shale in the slipped interval) is a typical threshold between minimal across-fault pressure difference and significant seal.

    For decades, the phrase {open_quotes}time, distance, and shielding{close_quotes} has been presented as summarizing the {open_quotes}basics{close_quotes} of radiation protection. Indeed, for protection from external radiation sources, these three principles are probably the most important ones on which a worker can make decisions and take actions. However, these principles do not address protection against intakes of radioactive materials or {open_quotes}ontakes{close_quotes} (skin contamination), other risk-limiting measures, or other important protective measures taken by governments, public health agencies, regulators, and institutional programs (measures such as performance standards, health education, facility engineering requirements, and administrative procedures). I have identified ten principles and ten accompanying commandments of radiation protection: time, distance, dispersal, source reduction, source barrier, personal barrier, decorporation, effect mitigation, optimal technology, and limitation of other exposures. Corresponding non-technical forms of the commandments are hurry (but don`t be hasty); stay away from it; disperse it and dilute it; use as little as possible; keep it in; keep it out; get it out or off of you (after intake or skin contamination); limit the damage; choose the best technology (perhaps a non-radiation technology); and don`t compound risks (don`t smoke). Technical versions of the commandments are also provided using the verbs {open_quotes}optimize,{close_quotes} {open_quotes}maximize,{close_quotes} or {open_quotes}minimize.{close_quotes} Not all commandments can be applied at the same time, and application may be different for workers and members of the public. Advantages, disadvantages, and implementation of these principles and commandments are discussed, and numerous examples provided. The application of the principles and commandments must be based on knowledge of the radiological conditions to be managed. 4 refs., 1 tab.

    A technique for predicting chaos arising in a broad class of nonlinear oscillatory systems is proposed. It is based on the notion of running Lyapunov exponents and uses the local stability properties of trajectories for determining the {open_quote}{open_quote}safe{close_quote}{close_quote} areas in the phase space where any trajectory is regular and stable in the sense of Lyapunov. The combination of this approach with harmonic balance method permits to obtain the corresponding {open_quote}{open_quote}safe{close_quote}{close_quote} regions in the control parameter space. The borders of these regions may be considered as threshold lines delimiting the areas of possible chaotic instability. An example of the two-well Duffing oscillator demonstrates good agreement between theoretically predicted values of control parameters where chaos arises with those obtained numerically. The technique is especially effective for rather high dissipation levels when other known methods such as Melnikov{close_quote}s criterion or combination of harmonic balance with analysis of variational equations fail to provide correct results. {copyright} {ital 1996 American Institute of Physics.}

    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.

The business of growing a business, then, can be framed as a matter of getting customers and keeping them so as to grow the value of the customer base to its fullest potential. In these terms, setting a marketing budget becomes the task of balancing what is spent on customer acquisition with what is spent on retention.

    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.

    The term {open_quotes}invariant embedding{close_quotes} derives from the fact that if a physical system is linear, in the sense that certain identified {open_quotes}output{close_quotes} properties (e.g., exiting fluxes) depend linearly in the mathematical sense on other {open_quotes}input{close_quotes} properties (e.g., entering fluxes), then that property is invariant to the system being embedded into a larger system (i.e., being a subsystem of such larger system). The basic idea of such {open_quotes}principles of invariance{close_quotes} go back at least to early work of Stokes, who applied them to radiative transfer (of light). The first application to nuclear radiation seems to have occurred in a 1907 paper of Schmidt. Although invariant embedding is often viewed as inherently limited to one-dimensional settings, at the level of generality described here, the well-known response matrix method (e.g., Weiss), which has been used for multidimensional radiation transport computations and recently even has been shown to be well suited to such computations on massively parallel systems, is an instance of invariant embedding. Ribarit has described an elaborate and fairly abstract calculus for (among other things) computing the input - output structures of any given (neutronic) system from those of a set of constituent subsystems.

    In order to achieve high sensitivity and maintain good uniform spatial resolution over the field of view in high resolution PET systems, adequate depth of interaction information must be extracted from the crystal. A phoswich detector can supply one solution to the depth of interaction problem In this approach, two or more scintillators exhibiting different light decay times are positioned on top of each other and separated by pulse shape discrimination. Initially, our experiments focused on separating different types of scintillators such as LSO and GSO or LSO and YSO. These combinations were all well separated as expected. During the investigation, a shift in the time distribution of different samples of LSO was noticed. Further investigation showed two groups of LSO. The shift in the zero cross time was more than twice the FWHM of the time distribution. A single photon experiment revealed that the decay time of the {open_quote}fast{close_quote} crystal was 31.9 nanoseconds while the decay of the {open_quote}slow{close_quote} crystal was 42.8 nanoseconds. A spectral plot revealed that the spectral output of the {open_quote}slow{close_quote} crystal was skewed to the longer wavelengths as compared to the {open_quote}fast{close_quote} crystal. Further investigation on other crystal samples revealed decay times between the two extremes, suggesting a continuum in the light decay.

    If competition is given free rein, the law of supply and demand will drive down the cost of producing power. In the best-case scenario, consumers may see as much as a 40-percent reduction in the price of electricity in the long run, say Michael T. Maloney, Robert E. McCormick, and Raymond D. Sauer, professors of economics at Clemson University in Clemson, South Carolina. A regulatory monopoly is doomed to failure, the authors say, because under that system {open_quotes}the more a firm spends, the more money it is allowed to make for its shareholders.{close_quotes} In addition, the authors discount the notion that government should bail out utilities for their capital investments-or stranded costs-during a transition period. {open_quotes}Efficient firms that invest prudently are rewarded with lower costs of capital in competitive markets, and this will remain so for competitive producers of electricity,{close_quotes} the authors say. {open_quotes}Any utility that is allowed to recover some or all of its stranded costs by regulatory fiat in the transition to competition will receive an economic windfall that will not cause it to change its behavior.{close_quotes} In fact, stranded costs are primarily the result of the experiment with nuclear energy. {open_quotes}Consumers are still paying for the cost overruns,{close_quotes} the authors say.

    Baker, J.E.

    1994-09-01

    Multi-Sensor Integration (MSI) is the combining of data and information from more than one source in order to generate a more reliable and consistent representation of the environment. The need for MSI derives largely from basic ambiguities inherent in our current sensor imaging technologies. These ambiguities exist as long as the mapping from reality to image is not 1-to-1. That is, if different {open_quotes}realities{close_quotes} lead to identical images, a single image cannot reveal the particular reality which was the truth. MSI techniques attempt to resolve some of these ambiguities by appropriately coupling complementary images to eliminate possible inverse mappings. What constitutes the best MSI technique is dependent on the given application domain, available sensors, and task requirements. MSI techniques can be divided into three categories based on the relative information content of the original images with that of the desired representation: (1) {open_quotes}detail enhancement,{close_quotes} wherein the relative information content of the original images is less rich than the desired representation; (2) {open_quotes}data enhancement,{close_quotes} wherein the MSI techniques are concerned with improving the accuracy of the data rather than either increasing or decreasing the level of detail; and (3) {open_quotes}conceptual enhancement,{close_quotes} wherein the image contains more detail than is desired, making it difficult to easily recognize objects of interest. In conceptual enhancement one must group pixels corresponding to the same conceptual object and thereby reduce the level of extraneous detail.

    The fragile X mutation is the expansion of a CGG repeat in the 5{prime} untranslated region of the FMR-1 gene to > 200 repeats. This expansion to the {open_quotes}full mutation{close_quotes} probably occurs during early embryogenesis in individuals who inherit a {open_quotes}premutation{close_quotes} allele containing >50 and <200 repeats. Analysis of blood samples from a series of 148 fragile X males showed that 40% were {open_quotes}mosaics{close_quotes} who carried a mixture of premutation and full mutation alleles. The proportion of the premutation allele varied widely which suggested that there may have been differences in the way the repeat expanded during development. We examined a subset of these affected {open_quotes}mosaic{close_quotes} males who exhibited very different mosaic DNA patterns. Southern blot analysis showed that these males had a range of approximately 10 to 80% premutation allele in their blood DNA. In fibroblast DNA, however, the premutation allele was present at less than 10% in all of these affected males. Since erythrocyte stem cell precursors appear to be established from a yolk sac lineage,earlier in development compared to skin fibroblasts, we hypothesize that this difference in the extent of mosaicism may reflect variation in the progression of the CGG expansion during development. The differences in the proportion of mosaic alleles in different tissues may also help explain the weak correlation between the mosaic DNA patterns of blood samples from mosaic males and their degree of mental retardation.

Once these people have completed their tour, their minds are eased. It is at that point that I ask them to do a simple word association test on themselves.

    1996-07-01

    Natural gas is becoming increasingly important as a fuel because of its widespread occurrence and because it has a less significant environmental impact than oil. Many of the known gas accumulations were discovered by accident during exploration for oil, but with increasing demand for gas, successful exploration will require a clearer understanding of the factors that control gas distribution and gas composition. Natural gas is generated by three main processes. In oxygen-deficient, sulfate-free, shallow (few thousand feet) environments bacteria generate biogenic gas that is essentially pure methane with no higher hydrocarbons ({open_quotes}dry gas{close_quotes}). Gas is also formed from organic matter ({open_quotes}kerogen{close_quotes}), either as the initial product from the thermal breakdown of Type III, woody kerogens, or as the final hydrocarbon product from all kerogen types. In addition, gas can be formed by the thermal cracking of crude oil in the deep subsurface. The generation of gas from kerogen requires higher temperatures than the generation of oil. Also, the cracking of oil to gas requires high temperatures, so that there is a general trend from oil to gas with increasing depth. This produces a well-defined {open_quotes}floor for oil{close_quotes}, below which crude oil is not thermally stable. The possibility of a {open_quotes}floor for gas{close_quotes} is less well documented and understanding the limits on natural gas occurrence was one of the main objectives of this research.

    It is well known that the optimal solution for searching in a finite total order set is the binary search. In binary search we divide the set into two {open_quotes}halves{close_quotes}, by querying the middle element, and continue the search on the suitable half. What is the equivalent of binary search, when the set P is partially ordered? A query in this case is to a point x {element_of} P, with two possible answers:{open_quote}yes{close_quote}, indicates that the required element is {open_quotes}below{close_quotes} x, or {open_quote}no{close_quote} if the element is not bellow x. We show that the problem of computing an optimal strategy for search in Posets that are tree-like (or forests) is polynomial in the size of the tree, and requires at most O(n{sup 2} log{sup 2} n) steps. Optimal solutions of such search problems are often needed in program testing and debugging, where a given program is represented as a tree and a bug should be found using a minimal set of queries.

Because much of the [open quotes]organic sulfur[close quotes] in fossil fuels is contained in benzo[2,3-b]thiophene and dibenzothiophene groupings, the coordination chemistry of these thiophenes has received considerable attention. In contrast, the coordination chemistry of the nonclassical thiophenes (for which all singlet, uncharged resonance forms invoke C-S double bonding) and benzo[3,4-c]thiophene (1, [open quotes]isothianaphthene[close quotes]) is completely undeveloped. Benzo[c]thiophene (1) is prepared by the dehydration of dihydrobenzo[c]thiophene oxide on alumina.

    The Environmental Evaluation Group (EEG) previously analyzed the probability of a catastrophic accident in the waste hoist of the Waste Isolation Pilot Plant (WIPP) and published the results in Greenfield (1990; EEG-44) and Greenfield and Sargent (1993; EEG-53). The most significant safety element in the waste hoist is the hydraulic brake system, whose possible failure was identified in these studies as the most important contributor in accident scenarios. Westinghouse Electric Corporation, Waste Isolation Division has calculated the probability of an accident involving the brake system based on studies utilizing extensive fault tree analyses. This analysis conducted for the U.S. Department of Energy (DOE) used point estimates to describe the probability of failure and includes failure rates for the various components comprising the brake system. An additional controlling factor in the DOE calculations is the mode of operation of the brake system. This factor enters for the following reason. The basic failure rate per annum of any individual element is called the Event Probability (EP), and is expressed as the probability of failure per annum. The EP in turn is the product of two factors. One is the {open_quotes}reported{close_quotes} failure rate, usually expressed as the probability of failure per hour and the other is the expected number of hours that the element is in use, called the {open_quotes}mission time{close_quotes}. In many instances the {open_quotes}mission time{close_quotes} will be the number of operating hours of the brake system per annum. However since the operation of the waste hoist system includes regular {open_quotes}reoperational check{close_quotes} tests, the {open_quotes}mission time{close_quotes} for standby components is reduced in accordance with the specifics of the operational time table.

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.

  20. Glacial marine sedimentation: Paleoclimatic significance

    1991-01-01

    This publication resulted from a symposium held during the 1988 Annual Meeting of the Geological Society of America. Many, but not all, contributors to the symposium have papers in this volume. This Special Paper consists of 14 chapters and a Subject/Geographic index. Each chapter has is own list of references. The papers cover a wide range of modem climate/ ocean environments, including papers on glacial marine sediments from Antarctica, the fiords of Alaska, and sediments from the Canadian High Arctic. In addition, three papers discuss [open quote]old[close quotes] glacial marine records (i.e., pre-Tertiary), and one paper discusses the Yakataga Formation of the Gulf of Alaska which is a Miocene-to-late-Pleistocene sequence. The last chapter in the book includes a survey and summary of the evidence for the paleoclimatic significance of glacial marine sediments by the two editors, John Anderson and Gail Ashley. It is worth noting that Anderson and Domack state in the Foreword that there is a considerable variation in terminology; hence they employ a series of definitions which they urge the other authors to employ. They define and explain what they mean by [open quotes]polar ice cap,[close quotes] [open quote]polar tundra (subpolar),[close quotes] and [open quotes]temperate oceanic and boreal[close quotes] in terms of the dominant glacial and glacial marine processes. Although one might quarrel with the terminology, the broad differences between these three glaciological regimes are indeed fundamental and need to be sought in the geological record. The flavor of the volume can be judged by some of the chapter titles. Contributions on Antarctica include a paper by Anderson and other entitled [open quote]Sedimentary facies associated with Antarctica's floating ice masses[close quotes] and a companion paper by Anderson and Domack which deals with the extremely complex glacial marine facies (13 facies are delimited) in McMurdo Sound, Antarctica.

Spectroscopic studies showed that resins contain both amide- and carboxylic groups, and the peak of {r_angle}NH of amine salts at (3000-2700 cm{sup {minus}1}) and (2700-2500 cm{sup {minus}1}) is disappeared. This indicates that the addition of acrylic acid monomer on ammonium groups. These ammonium groups in template polymers are converted into acrylic acid chain ends in the obtained resins accordingly, the probability of the polymer degradation of decreases may be attributed to the high radiation stability of these chain ends of acrylic acid units. The capacities of the obtained resins increase by increasing the absorbed doses of about {approximately}20 kGy, but at high doses the capacities decrease. On increasing the amines ratio in template polymers the capacities of resins for cation decreased but increased for anions. The capacities of the product materials to some heavy metal ions decrease with increasing the hydrogen ion concentrations and the selectivity is decreased in the order Cu{sup 2+} > Co{sup 2+} > Cs{sup +}.

    The objective of the paper is to present a framework for the application of {open_quotes}Performance Parameters{close_quotes} for the long-term management of existing AAR-affected dams and hydroelectric plants as a basis for discussion in the workshop on dam safety issues. In this paper, references are made to various cases and the reader is referred to the companion paper for supporting information. The concept of {open_quotes}Performance Parameters{close_quotes} is being introduced by USBR as part of their dam safety program development. The focus is on dam safety related issues and parameter development starts with identification of failure modes of a dam, key performance parameters, and then progresses into definition of instrumentation and monitoring systems and potential action plans. Dam safety deficiencies and powerplant operational problems have been identified in several dams around the world and structural modifications either implemented or planned. In others, where slow (ASSR) or indefinitely continuing reactions (with {open_quotes}auto-generation{close_quotes} of alkalis) are occurring, it is necessary to plan a suitable monitoring and long management program which addresses the apparently {open_quotes}mild{close_quotes} degree of the problem but addresses the future potential in a realistic but not overly pessimistic manner. {open_quotes}Generic{close_quotes} performance parameters to address AAR effects based on a review of cases are proposed here as a possible guide to site specific development in actual cases. These are extended from the USBR scope in two respects: firstly, to include dam, spillway and plant operational issues, and secondly, into two levels of detail and effort. This discussion will be primarily a review of failure modes and key parameters. Techniques for forecasting and monitoring these parameters in an AAR environment are briefly reviewed.

    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.

    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}

A map f is defined to be tractable (relative to A and R), if this procedure always leads to a global optimum. While it is not too interesting to search for all f which are tractable - the family of such f appears to be too wild for most choices of A and R to allow a reasonable description -, the situation changes drastically once we introduce in addition a vector space V of real valued maps defined on X and ask for all maps f as above for which all sums f+v with v in V are tractable. In the lecture, I will discuss various basic and interesting choices for X, A, R, and V and characterize the resulting family of {open_quote}(A, R, V)-tractable{close_quote} maps f by corresponding matroid-like {open_quote}local{close_quote} combinatorial conditions on f, leading to the definition of valuated matroids, valuated Delta-matroids, and the like.

    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}.

    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 integration of optical components with polysilicon surface micromechanical actuation mechanisms shows significant promise for signal switching, fiber alignment, and optical sensing applications. The optical and stress properties of the oxides and nitrides considered for optical waveguides and how they are integrated with micromechanical devices were investigated.

    1996-12-31

    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.

    We study the influence of plastic predeformation by bending to create deep residual compressive stresses on the fatigue strength of 13Kh11N2V2MF steel specimens and compressor blades with cut and stamped V-shaped and semicircular defects, and also the use of design-based redistribution of the stresses in the blade ({open_quotes}offsetting{close_quotes} toward the edges) for the retardation of cracks in the stress concentrators. It is found that plastic predeformation increases the fatigue strength by about 20%, while {open_quotes}offsetting{close_quotes} with the creation of a compressive mean stress {sigma}{sub m} = -300 MPa in the defect region increases the fatigue strength by 2-2.5 times. We examine schemes for calculating the fatigue strength with account for the residual and mean stresses, and also examine the defect creation technique. Recommendations are made for increasing the strength of compressor blades with defects.

    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.

    This paper is a case history comparing and evaluating the effects of fracturing the Reef Ridge Diatomite formation in the Midway-Sunset Field, Kern County, California, using {open_quotes}select-fire{close_quotes} and {open_quotes}point-source{close_quotes} perforating completions. A description of the reservoir, production history, and fracturing techniques used leading up to this study is presented. Fracturing treatment analysis and production history matching were used to evaluate the reservoir and fracturing parameters for both completion types. The work showed that single fractures were created with the point-source (PS) completions, and multiple fractures resulted from many of the select-fire (SF) completions. A good correlation was developed between productivity and the product of formation permeability, net fracture height, bottomhole pressure, and propped fracture length. Results supported the continued development of 10 wells using the PS concept with a more efficient treatment design, resulting in substantial cost savings.

    Recent investigators have shown that the performance of polymer matrix composites can be significantly enhanced by using fibers sized with a thermoplastic polymer. This increase in performance is a result of the sizing material interacting with the matrix resin to form an interphase: a region possessing a gradient in properties different from the sizing material and the matrix resin. Although the influence of the sizing (interphase) on laminate properties has been well documented, quantitative information regarding interphase properties is absent. In this study, {open_quotes}model{close_quotes} composites consisting of polyurethane sized carbon fibers embedded in a vinyl ester matrix were fabricated to characterize the interphase. The atomic force microscope was used to identify the interphase region in these {open_quotes}model{close_quotes} composites.

    The null tetrad formalism is used to investigate the structure of the Einstein field equations for Kerr{endash}Schild gravitational fields in the presence of an elastic solid source. It is shown that such equations may be reduced to five nonlinear partial differential equations for five variables. It turns out that, when the interior solutions admit the same preferred null congruence of the vacuum ones and some compatibility conditions hold, it is possible to reduce them to a linear system and to develop a method of solution which closely resembles the {open_quote}{open_quote}variation of the arbitrary constants{close_quote}{close_quote} for ordinary differential equations. In the present paper, the above technical framework is developed in general and applied to two simple examples, deferring to future work the approach to the Kerr{endash}interior problem. {copyright} {ital 1996 American Institute of Physics.}

    This paper presents the personal view of the lecturers teaching solid body mechanics to first year undergraduates in Mechanical Engineering in a UK university, and outlines some of the pressures that have been, and continue to be exerted on institutions and their staff. The way in which the sandwich scheme is integrated with the academic elements of the undergraduate courses in Mechanical Engineering at Brunel University are described, and observations about the way in which these have been strongly influenced by expressed Industrial needs are outlined. The way in which the course structures at Brunel University have moved from {open_quote}All Sandwich{close_quote} to a more {open_quote}Mixed Economy{close_quote} is outlined. The paper identifies some of the current influences on teachers in the University sector, and makes reference to changes to the schools` curricula, the changing nature of entrance qualifications, and hence the changing background ability of the student body.

    Nothing has improved petroleum product loading in recent years more than terminal automation systems. The presence of terminal automation systems (TAS) at loading racks has increased operational efficiency and safety and enhanced their accounting and management capabilities. However, like all finite systems, they occasionally malfunction or fail. Proper servicing and maintenance can minimize this. And in the unlikely event a TAS breakdown does occur, prompt and effective troubleshooting can reduce its impact on terminal productivity. To accommodate around-the-clock loading at racks, increasingly unattended by terminal personnel, TAS maintenance, servicing and troubleshooting has become increasingly demanding. It has also become increasingly important. After 15 years of trial and error at petroleum and petrochemical storage and transfer terminals, a number of successful troubleshooting programs have been developed. These include 24-hour {open_quotes}help hotlines,{close_quotes} internal (terminal company) and external (supplier) support staff, and {open_quotes}layered{close_quotes} support. These programs are described.

    Before its discovery chaos was inevitably confused with randomness and indeterminacy. Because may systems {ital appeared} random, they were actually thought to {ital be} random. This was true despite the fact that many of these systems seemed to display intermittent almost periodic behavior before returning to more {open_quote}{open_quote}random{close_quote}{close_quote} or irregular motion. Indeed this observation leads to one of the defining features of chaos: the superposition of a very large number of unstable periodic motions. Thus the identification in biological systems of unstable periodic or fixed point behavior consistent with chaos makes new therapeutic strategies possible. Recently we were able to exploit such unstable periodic fixed points to achieve control in two experimental systems: in cardiac tissue and brain tissue. {copyright} {ital 1996 American Institute of Physics.}
