The feasibility of conducting human missions to the Moon is examined assuming the use of three {open_quote}{open_quote}high leverage{close_quote}{close_quote} technologies: (1) a single-stage-to-orbit (SSTO) launch vehicle, (2) {open_quote}{open_quote}{ital in}-{ital situ}{close_quote}{close_quote} {ital resource} {ital utilization} (ISRU){emdash}specifically {open_quote}{open_quote}lunar-derived{close_quote}{close_quote} liquid oxygen (LUNOX), and (3) LOX-augmented nuclear thermal rocket (LANTR) propulsion. Lunar transportation system elements consisting of a LANTR-powered lunar transfer vehicle (LTV) and a chemical propulsion lunar landing/Earth return vehicle (LERV) are configured to fit within the {open_quote}{open_quote}compact{close_quote}{close_quote} dimensions of the SSTO cargo bay (diameter: 4.6 m/length: 9.0 m) while satisfying an initial mass in low Earth orbit (IMLEO) limit of {approximately}60 t (3 SSTO launches).

Stable maps and Quot schemes  

NASA Astrophysics Data System (ADS)

In this paper we study the relationship between two different compactifications of the space of vector bundle quotients of an arbitrary vector bundle on a curve. One is Grothendieck's Quot scheme, while the other is a moduli space of stable maps to the relative Grassmannian. We establish an essentially optimal upper bound on the dimension of the two compactifications. Based on that, we prove that for an arbitrary vector bundle, the Quot schemes of quotients of large degree are irreducible and generically smooth. We precisely describe all the vector bundles for which the same thing holds in the case of the moduli spaces of stable maps. We show that there are in general no natural morphisms between the two compactifications. Finally, as an application, we obtain new cases of a conjecture on effective base point freeness for pluritheta linear series on moduli spaces of vector bundles.

Can light Nambu-Goldstone boson loops counter the {open_quote}{open_quote}{ital S} argument{close_quote}{close_quote} against technicolor?

We examine the oblique correction phenomenology of one-family technicolor with light pseudo Goldstone bosons. From loop calculations based on a gauged chiral Lagrangian for technicolor we are led to conclude that even though loops with light Goldstone bosons give a negative contribution to {ital S} measured at the {ital Z} pole, this effect is not sufficiently large to unambiguously counter the {open_quote}{open_quote}{ital S} argument{close_quote}{close_quote} against one-family technicolor.

Peculiar fragile X {open_quotes}mosaics{close_quotes} suggest deletion from full mutations as a mechanism for generating {open_quotes}mosaic{close_quotes} cases  

SciTech Connect

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.

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

SciTech Connect

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

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

SciTech Connect

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

A {open_quotes}New{close_quotes} regime for nuclear weapons and materials  

SciTech Connect

In this paper, I discuss the principal ideas that I covered in my presentation on December 8, 1993, at the Future of Foreign Nuclear Materials Symposium held by the Naval Postgraduate School in Monterey, California. I was asked to discuss issues related to military inventories of plutonium, and I took this opportunity to describe a possible declaratory regime that could encompass military as well as civilian inventories of plutonium. The {open_quote}new{close_quotes} in the title does not imply that the regime discussed here is an original idea. Rather, the regime will be {open_quotes}new,{close_quotes} when it is adopted. The regime proposed here and in other works is one in which all stocks of nuclear weapons and materials are declared. Originally, declarations were proposed as a traditional arms control measure. Here, declarations are proposed to support the prevention of misuse of nuclear weapons and materials, including support for the nonproliferation regime. In the following, I discuss: (1) Worldwide inventories of nuclear weapons and materials, including the fact that military plutonium must be viewed as part of that worldwide inventory. (2) Life cycles of nuclear weapons and materials, including the various stages from the creation of nuclear materials for weapons through deployment and retirement of weapons to the final disposition of the materials. (3) Mechanisms for making declarations. (4) Risks and benefits to be derived from declarations. (5) Possibilities for supporting evidence or verification.

A [open quotes]stratified[close quotes] spectral model for stable and convective atmospheres  

SciTech Connect

In our solar system, convective atmospheres are as common as those that are stable, and convective and stable regions sometimes coexist in the same atmosphere. There is a need to develop circulation models that can handle convection and stable-layer flows simultaneously and efficiently. This paper represents and approach to the construction of such a model. Taking advantages of the simplicity of implementing implicit time stepping in spectral models, we solve a non-hydrostatic, fully compressible version of the hydrodynamic equations without the time step restrictions imposed by acoustic and gravity waves. To simplify the nonlinear terms and to conserve the total mass and total angular momentum to round-off accuracy, we introduce a [open quotes]stratified[close quotes] approximation which limits the nonlinearity of the equations to quadratic. The linear terms remain intact so that all the linear waves are preserved. The set of assumptions made by the [open quotes]stratified[close quotes] approximation is a subset of those of the anelastic approximation. It offers more generality and accuracy while the computational overhead is relatively low. Tests are presented to illustrate the capabilities and advantages of the present model. 49 refs., 6 figs., 2 tabs.

Optimal {open_quotes}Adders{close_quotes} for environmental damage by public utilities  

SciTech Connect

{open_quotes}Social costing{close_quotes} refers to the consideration of environmental damages and other external costs and benefits in resource planning or dispatch decisions by electric utilities. Typically, utility regulators must take existing regulations promulgated by other levels of government as parametric, so social costing represents a second layer of regulatory review with regard to many issues. The consideration of external costs at the level of utility regulation will have efficiency implications that are not obvious. For example, the practice is particularly contentious when it is believed that industry emissions of a pollutant are {open_quotes}overcontrolled,{close_quotes} in that they are subject to an emission limitation more stringent than what would be considered economically efficient. Within a simple but fairly general normative model, this paper presents some simple analytics for the consideration of social costs in utility decision making, assuming the objective of the regulator is to maximize social welfare. The efficient policy depends on the institutional characteristics of preexisting regulation. The role of deviations from marginal cost pricing in electricity pricing and the possibility of customer bypass of the utility grid are explicitly modeled. 31 refs., 2 figs., 1 tab.

Results of {open_quotes}Heisenberg Microscope{close_quotes} decoherence atom interferometry experiments  

SciTech Connect

We present results of atom interferometry experiments in which spatial matter - wave interference is revealed by its selective destruction. A thermal potassium beam is transmitted through a velocity selective atom interferometer and detected. The interferometer is a sequence of three diffraction gratings. Interference fringes forming a Moire pattern with the third grating determine the transmission. The thermal beam produces a velocity average over different fringe Fourier components, each resonant in the interferometer at a different atomic velocity. AC modulated laser light passes through the interferometer, near the middle grating. Since imaging of the fluorescent light could be used to determine which slit an atom passes, the contribution to the fringe pattern by atoms at the laser`s Doppler shifted wavelength is removed. That component is thus AC modulated and detected. This {open_quotes}atom interference filter{close_quotes} resolves the K{sup 39} HFS.

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

SciTech Connect

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

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

SciTech Connect

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

Coal air turbine {open_quotes}CAT{close_quotes} program, Invention 604. Third quarter project report, April 1995--June 1995  

SciTech Connect

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

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

SciTech Connect

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

Identification of mutations by RNA conformational polymorphism {open_quotes}bar code{close_quotes} analysis  

SciTech Connect

DNA single-strand conformational polymorphism (SSCP) analysis is widely used for detection of point mutations in clinical specimens. Performing SSCP analysis with cRNA instead of DNA has been shown to improve mutation detection frequency. RNA can exist in numerous metastable conformations, which appear as patterns of bands on nondenaturing electrophoresis gels. Single base mutations can cause not only mobility shifts of major bands, but also loss of some conformations and appearance of new conformations. Unique RNA SSCP patterns associated with specific base sequences in many cases allow visual identification of point mutations. However, in some cases, the RNA SSCP pattern of a single base change in a sequence is not sufficiently different for a positive identification of the mutation. Improvement in the detection capability of RNA SSCP was obtained by adding 3{prime}-deoxy-nucleotides to the transcription reaction. The presence of chain-terminating nucleotides in the transcription reaction formed numerous new RNA fragments, thereby generating complex band patterns ({open_quotes}bar codes{close_quotes}) unique to each RNA sequence. This method was applied to analyzing p53 mutations in patients with colon cancer. 8 refs., 3 figs.

{open_quotes}Unspecific{close_quotes} X-linked mental retardation: Clinical, genetic and molecular studies  

SciTech Connect

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.

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

SciTech Connect

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

Upper stage options for reusable launch vehicle {open_quotes}pop-up{close_quotes} missions  

SciTech Connect

Suborbital separation of an expendable upper stage from a small, single-stage Reusable Launch Vehicle (RLV) to transfer spacecraft into Geosynchronous Equatorial Orbit (GEO) was investigated and found to significantly increase spacecraft mass into GEO (over 400{percent}) although operational issues exist. An assessment of propulsion system options for this {open_quotes}Pop-Up{close_quotes} Mission was performed to determine the propellant combinations, stage configurations, and propulsion technologies that maximize spacecraft mass and minimize size. Propellants included earth and space storable combinations, cryogenic LH{sub 2}/LO{sub 2}, and Class 1.3 solids. Stage configurations employing cylindrical metal and overwrapped tanks, isogrid tanks, and toroidal tanks were considered. Non-toxic earth storable propellants provided comparable performance (5{endash}10{percent}) to existing storables while the use of pressure-fed engines gave about 15{percent} lower performance than pump-fed. Solid stage performance was within 5{percent} of existing storable propellants. Stages employing toroidal tanks packaged more efficiently in length constrained RLV payload bays than 4-cylindrical tank configurations, giving up to 30{percent} greater mass into GEO. The use of Extendable Exit Cones (EEC) for length constrained cases resulted in about 5{endash}10{percent} higher stage performance. {copyright} {ital 1997 American Institute of Physics.}

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

SciTech Connect

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

The Athabasca tar sands of northeastern Alberta contain 13 trillion bbl of bitumen in place, 5% of which is accessible by surface mining techniques. If there is to be significant exploitation of the deeper buried resources, it will have to be done using subsurface [open quotes]in-situ[close quotes] technologies. Compared to surface mining, these methods are potentially more economic, can be developed on a smaller scale and are environmentally more sound. The Lower Cretaceous McMurray Formation is by far the richest hydrocarbon bearing unit in Canada. Overall, it is a transgressive sand and mud dominated unit deposited in fluvial to marine environments. The main reservoir unit is an estuarine sand, whole complexity makes for an elusive exploration target and a challenging development project. Successful reservoir management of a subsurface [open quotes]in-situ[close quotes] operation depends on a solid understanding of estuarine stratigraphy and its lithologic heterogeneities. For the past 20 years, Chevron has been developing an [open quotes]in-situ[close quotes] heavy oil extraction process called HASDrive (Heated Annulus Steam Drive). Recently, HASDrive and other technologies have been employed on a 77 mi[sup 2] lease with 9 billion bbl of heavy oil in place. The goal is to bring the lease to a fully commercial 10,000 bbl/day operation by 1997. In the exploration phase, 64 core hole wells were located with the aid of shallow 3-D seismic and electromagnetic techniques. The current pilot phase has utilized HASDrive to extract the bitumen from and sand and specialized seismic methods to monitor the development of the steam chamber.

Solar cycle and the Pacific {open_quote}centers of action{close_quote}  

SciTech Connect

The sun{close_quote}s integrated irradiance varies by about 0.1{percent} during its 11 year cycle, a change that is apparently too small to directly alter the mean climate of the earth. Yet, large correlations between the sunspot cycle and local climate variables have been noted. In this study the variations of the semi-permanent pressure systems the Aleutian Low and the Hawaiian High are investigated. It is found that extremes in solar variability as measured by the mean annual sunspot numbers, correlate highly with the locations of these centers of action. The Aleutian Low migrates eastward during minimum solar activity and the Hawaiian High migrates southward. Effects on the intensity of the Centers of Action were also significant and were in general agreement with recent theoretical results. Because shifts in the Centers of Action change storm trajectories, large anomalies in regional climatic conditions can be generated in the extreme phases of the solar cycle.{copyright} 1997 American Geophysical Union

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

Absence of {lambda} immunoglobulin sequences on the supernumerary chromosome of the {open_quotes}cat eye{close_quotes} syndrome  

SciTech Connect

The supernumerary bisatellited chromosome causing the {open_quotes}cat eye{close_quotes} syndrome (CES) is of chromosome 22 origin and consists of an inverted duplication of the 22pter{r_arrow}22q11.2 region. To determine the extent of involvement of band q11.2 on the bisatellited chromosome, copy number assessment of sequences homologous to cloned {lambda} immunoglobulin ({lambda} Ig) gene region probes was carried out on DNA from individuals with CES using densitometric analysis of Southern blots. None of the 10 {lambda} Ig sequences studied was found in increased copy number in DNA from any of the 10 CES individuals tested, indicating that these sequences are not present on the supernumerary chromosome. The breakpoints involved in the generation of the bisatellited supernumerary chromosome associated with CES are therefore proximal to the {lambda} Ig gene region. 20 refs., 1 fig., 3 tabs.

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

Search systems and medical data quoting from the internet.  

PubMed

The Internet as a new medium also has its use in medicine. Plenty of information which can be found on the world computer network, needs an efficient searching as well as an evaluation system and quoting of the information obtained. Twelve most popular search engines were chosen--9 general: Netscape, Altavista, HotBot, Goggle, Northern Light, Magellan, Infoseek, MSN; 2 specialized medical search engines: Medscape and Medline; and one Croatian search engine: Cross. The efficiency of searching was observed by analyzing the number of obtained pages, their contents and examples of the quoted references from the Internet. The searching was done using the mentioned search engines, and results varied from 2,189,793 network pages found on the Infoseek for the term 'skin cancer' to 0 pages with the search engine Cross for the term 'melanoma+therapy'. When comparing the results for a single term using various search engines, it is concluded that the number of pages varied because of different databases and specialized scooters that search and make indexes. It is possible to use logical operators and more advanced search systems with the majority of search engines. The quoting system is based on mentioning the names of the author and his work, the access date and url (uniform resource locator) addresses of the network pages. Permanent and reliable access to quotations could not be established with previous quotation systems. Dermatologic terms have been well dealt with concerning general population, whereas professionals are recommended to use Medline and reviewed web pages. There have been very few professional and professionally relevant and comprehensive pages on the Internet relative to the total of web pages. PMID:12377112

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

SciTech Connect

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

Another look at US passenger vehicle use and the {open_quotes}rebound{close_quotes} effect from improved fuel efficiency

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.

Comments on {open_quotes}datalog: A self-contained tutorial{close_quotes} by S. Ceri, G. Gottlob, and L. Tanca  

SciTech Connect

The construction of deductive databases requires a combination of independently developed methods for database management and logic programming. This approach has rapidly (literally in the last 5-6 years) coalesced within projects associated with combining new information technologies and fifth-generation computer systems (the strategic programs of the USA and Japan. and the ESPRIT program in Europe). Work has proceeded so rapidly and new methods have appeared at such a rapid pace that practically no information is available in the Russian-language literature. The number of publications in this area is large. and the sources are very diverse. As a result, providing an introduction to deductive databases is a nontrivial problem. However, the problem has been somewhat simplified by the recent appearance of two monographs that summarize achievements in this area: J. Ullman`s two-volume {open_quotes}Principles of Database and Knowledgebase Systems{close_quotes}, and the book {open_quotes}Logic Programming and Databases{close_quotes}, by Ceri, Gottlob, and Tanca. Ullman`s two volumes provide an exhaustive overview of the subject: They also consider results that are already considers classical. The book by Ceri, et. al., is concerned exclusively with new methods that are promising and have practical applications. The publisher {open_quotes}Mir{close_quotes} has completed a translation of this book. Publication of the article by Ceri, Gottlob, and Tanca makes it possible to efficiently inform the readers of {open_quotes}Programmirovanie{close_quotes} about the basic results in the indicated areas. It is the first publication of this type of article. It is base on a report made at the Polytechnic Institute of Milan and was provided through the courtesy of S.

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

SciTech Connect

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

Sequence stratigraphic re-interpretation of [open quotes]stray[close quotes] sandstones in the Cretaceous Mancos Shale, Book Cliffs, Utah: Implications for exploration models  

SciTech Connect

The Mancos Shale, Book Cliffs, eastern Utah, represents the open marine mudstones of the Cretaceous Western Interior Seaway and contains a number of detached sandstone bodies ([open quotes]Mancos B[close quotes]) which are located 30-150 km down depositional dip from contemporaneous highstand shoreline deposits in the Blackhawk Formation. Examination of these [open quotes]stray[close quotes] sandstones reveals that they do not represent deep water deposition, as previously supposed, but instead comprise three shallow marine facies associations; (1) tidally-influenced fluvial channel fills, (2) fluvially-dominated delta front successions and (3) low-energy shorelines. Tidally-influenced fluvial channel fills are commonly stacked into multistorey bodies at discrete stratigraphic levels, thereby defining incised valley fill (IVF) networks. Fluvially-dominated deltas are eroded into by, and lie at the down-dip terminations of, IVFs and are therefore interpreted as falling stage and lowstand shorelines. Low-energy shorelines are inferred to lie along strike from these deltas. The above shallow marine deposits have been mapped at five discrete stratigraphic horizons, which can be either traced or projected up-dip to previously-documented IVFs in the Blackhawk Formation. Their paleocurrents imply that falling stage and lowstand shoreline trends were sub-parallel to mapped highstand shorelines, although there is evidence for a perpendicular lowstand shoreline trend in the east of the study area. This facies and sequence stratigraphic re-interpretation enables predictive exploration modelling of subsurface [open quotes]Mancos B[close quotes] gas reservoir sandstones.

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

SciTech Connect

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

{open_quotes}Horizontal{close_quotes} gene transfer from a transgenic potato line to a bacterial pathogen (Erwinia chrysanthemi) occurs - if at all - at an extremely low frequency  

SciTech Connect

The frequency of possible {open_quotes}horizontal{close_quotes} gene transfer between a plant and a tightly associated bacterial pathogen was studied in a model system consisting of transgenic Solanum tuberosum, containing a {beta}-lactamase gene linked to a pBR322 origin of replication, and Erwinia chrysanthemi. This experimental system offers optimal conditions for the detection of possible horizontal gene transfer events, even when they occur at very low frequency. Horizontal gene transfer was not detected under conditions mimicking a {open_quotes}natural{close_quotes} infection. The gradual, stepwise alteration of artificial, positive control conditions to idealized natural conditions, however, allowed the characterization of factors that affected gene transfer, and revealed a gradual decrease of the gene transfer frequency from 6.3 x 10{sup -2} under optimal control conditions to a calculated 2.0 x 10{sub -17} under idealized natural conditions. These data, in combination with other published studies, argue that horizontal gene transfer is so rare as to be essentially irrelevant to any realistic assessment of the risk involved in release experiments involving transgenic plants. 22 refs., 3 figs., 2 tabs.

Implications of high-energy photons and electrons on target preheat at the Sandia {open_quotes}Z{close_quotes} facility  

SciTech Connect

High-energy photons and electrons on the Sandia National Laboratories {open_quotes}Z{close_quotes} accelerator, a {ital z}-pinch device, will deposit energy into a capsule and fuel; this may create a potential preheat problem for inertial confinement infusion (ICF). In this article we discuss heating of the capsule and fuel by high-energy photons and electrons. The fuel is heated to {lt}2 eV, in a time-integrated sense, on Z by these particles. Because peak implosion occurs at the peak in the soft x-ray emission on Z, the heating at times of interest is reduced roughly an order of magnitude to {approximately}0.2 eV for times of interest and fuel preheat from this mechanism is concluded to be small. These estimates are generated from time-integrated bremsstrahlung measurements. The uncertainty in the heating is high because the electron spectrum is not known directly, but inferred. In addition, the influence of photons and electrons at energies between 5 and 60 keV is not known. Given the uncertainties at this point, we do not know the impact on the feasibility of internal dynamic hohlraums for a {ital z}-pinch-driven ICF implosion. We discuss these issues and suggest directions for further study. {copyright} {ital 1999 American Institute of Physics.}

Characterization of the gene encoding nitrite reductase and the physiological consequences of its expression in the nondenitrifying Rhizobium {open_quotes}hedysari{close_quotes} strain HCNT1  

SciTech Connect

Rhizobium {open_quotes}hedysari{close_quotes} HCNT1 is an unclassified rhizobium which contains a nitric oxide-producing nitrite reductase but is apparently incapable of coupling the reduction of nitrite to energy conservation. The gene encoding the nitrite reductase, nirK, has been cloned and sequenced and was found to encode a protein closely related to the copper-containing family of nitrite reductases. Unlike other members of this family, nirK expression in HCNT1 is not dependent on the presence of nitrogen oxides, being dependent only on oxygen concentration. Oxygen respiration of microaerobically grown Nir-deficient cells is not affected by concentrations of nitrite that completely inhibit oxygen respiration in wild-type cells. This loss of sensitivity suggests that the product of nitrite reductase, nitric oxide, is responsible for inhibition of oxygen respiration. By using a newly developed chemically modified electrode to detect nitric oxide, it was found that nitrite reduction by HCNT1 produces significantly higher nitric oxide concentrations than are observed in true denitrifiers. This indicates that nitrite reductase is the only nitrogen oxide reductase active in HCNT1. The capacity to generate such large concentrations of freely diffusible nitric oxide as a consequence of nitrite respiration makes HCNT1 unique among bacteria. 33 refs., 6 figs., 1 tab.

Linkage disequilibrium in the insulin gene region: Size variation at the 5{prime} flanking polymorphism and bimodality among {open_quotes}Class I{close_quotes} alleles  

SciTech Connect

The 5{prime} flanking polymorphism (5{prime}FP), a hypervariable region at the 5{prime} end of the insulin gene, has {open_quotes}class 1{close_quotes} alleles (650-900 bp long) that are in positive linkage disequilibrium with insulin-dependent diabetes mellitus (IDDM). The authors report that precise sizing of the 5{prime}FP yields a bimodal frequency distribution of class 1 allele lengths. Class 1 alleles belonging to the lower component (650-750 bp) of the bimodal distribution were somewhat more highly associated with IDDM than were alleles from the upper component (760-900 bp), but the difference was not statistically significant. They also examined 5{prime}FP length variation in relation to allelic variation at nearby polymorphisms. At biallelic RFLPs on both sides of the 5{prime}FP, they found that one allele exhibits near-total association with the upper component of the 5FP class 1 distribution. Such associations represent a little-known but potentially wide-spread form of linkage disequilibrium. In this type of disequilibrium, a flanking allele has near-complete association with a single mode of VNTR alleles whose lengths represent consecutive numbers of tandem repeats (CNTR). Such extreme disequilibrium between a CNTR mode and flanking alleles may originate and persist because length mutations at some VNTR loci usually add or delete only one or two repeat units. 22 refs., 5 figs., 6 tabs.

The {open_quotes}Micromorph{close_quotes} cell: a new way to high-efficiency-low-temperature crystalline silicon thin-film cell manufacturing?  

SciTech Connect

Hydrogenated microcrystalline Silicon ({mu}c-Si:H) produced by the VHF-GD (Very High Frequency Glow Discharge) process can be considered to be a new base material for thin-film crystalline silicon solar cells. The most striking feature of such cells, in contrast to conventional amorphous silicon technology, is their stability under light-soaking. With respect to crystalline silicon technology, their most striking advantage is their low process temperature (220{degree}C). The so called {open_quotes}micromorph{close_quotes} cell contains such a {mu}c-Si:H based cell as bottom cell, whereas the top-cell consists of amorphous silicon. A stable efficiency of 10.7{percent} (confirmed by ISE Freiburg) is reported in this paper. At present, all solar cell concepts based on thin-film crystalline silicon have a common problem to overcome: namely, too long manufacturing times. In order to help in solving this problem for the particular case of plasma-deposited {mu}c-Si:H, results on combined argon/hydrogen dilution of the feedgas (silane) are presented. It is shown that rates as high as 9.4 {Angstrom}/s can be obtained: furthermore, a first solar cell deposited with 8.7 {Angstrom}/s resulted in an efficiency of 3.1{percent}. {copyright} {ital 1997 American Institute of Physics.}

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

SciTech Connect

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

Background: An HIV-specific version of the QUOTE questionnaire was developed to measure the quality of care of patients infected with HIV from the patients' perspective. The consistency and validity of the questionnaire was assessed. Methods: Focus group discussions were held to select aspects for inclusion in the questionnaire that are important to patients with HIV. Item and inter-item analysis, factor analysis, and reliability analysis were performed to test the internal consistency and validity of the questionnaire. Results: Twenty seven items (13 generic and 14 HIV specific) were used in the QUOTE-HIV questionnaire. Separate factor analyses of the generic and HIV specific aspects indicated that each loaded onto a single factor. The internal consistency of the total questionnaire was good (Cronbach's alpha ?0.80). Feasibility of the questionnaire was shown by the diversity of importance and performance scores for general practitioners as well as for HIV specialists and AIDS nursing consultants. Conclusion: The QUOTE-HIV questionnaire is a useful instrument for measuring the quality of care from the perspective of HIV infected patients.

Improved clearance of radiolabeled biotinylated monoclonal antibody following the infusion of avidin as a {open_quotes}chase{close_quotes} without decreased accumulation in the target tumor  

SciTech Connect

The techniques of radioimmunoimaging and radioimmunotherapy suffer from prolonged high background radioactivity because intravenously injected antibodies remain in the circulation and in the organs far longer than necessary for effective binding to the target. To decrease background and increase radionuclide excretion without decreasing the dose of radioactivity delivered to the target tumor, we used radiolabeled biotinylated antibodies followed by a {open_quotes}chase{close_quotes} avidin injection. A mouse monoclonal antibody, OST7 (lgG1), which reacts with human osteosarcoma, was biotinylated and labeled with {sup 125}I, {sup 131}I or {sup 22m}Tc. Radiolabeled biotinylated OST7 (10 {mu}g) was administered intravenously into nude mice bearing human osteosarcomas and 30 {mu}g of avidin was injected intravenously 6 or 24 hr later. Following avidin injection in mice pretreated with radiolabeled biotinylated antibodies, radioactivity was promptly cleared from the blood and deposited in the liver and spleen, after which radioiodine was rapidly detached from the antibody and excreted in the urine. The tumor-to-blood ratios at 6 and 24 hr after the injection of {sup 125}I-labeled biotinylated OST7 increased compared with the values before the avidin chase without any loss of tumor radioactivity. Furthermore, the tumor -to-background radioactivity ratio was improved and better images were obtained more rapidly after the injection of radiolabeled biotiny-lated antibodies than with conventional immunoscintigraphy. This method may find application in clinical radio-immunoimaging, especially using short half-life radionuclides such as {sup 39m}Tc and {sup 123}I. 24 refs., 8 figs., 3 tabs.

Depositional facies and porosity development at Coon Creek Field (Newman [open quotes]Big Lime[close quotes]), Leslie County, Kentucky  

SciTech Connect

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 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.

Frequency analysis of tick quotes on foreign currency markets and the double-threshold agent model  

NASA Astrophysics Data System (ADS)

Power spectrum densities for the number of tick quotes per minute (market activity) on three currency markets (USD/JPY, EUR/USD, and JPY/EUR) are analyzed for periods from January 2000 to December 2000. We find some peaks on the power spectrum densities at a few minutes. We develop the double-threshold agent model and confirm that the corresponding periodicity can be observed for the activity of this model even though market participants perceive common weaker periodic information than threshold for decision-making of them. This model is numerically performed and theoretically investigated by utilizing the mean-field approximation. We propose a hypothesis that the periodicities found on the power spectrum densities can be observed due to nonlinearity and diversity of market participants.

The next linear collider test accelerator{close_quote}s RF pulse compression and transmission systems  

SciTech Connect

The overmoded rf transmission and pulsed power compression system for SLAC{close_quote}s Next Linear Collider (NLC) program requires a high degree of transmission efficiency and mode purity to be economically feasible. To this end, a number of new, high power components and systems have been developed at X-band, which transmit rf power in the low loss, circular TE{sub 01} mode with negligible mode conversion. In addition, a highly efficient SLED-II [1] pulse compressor has been developed and successfully tested at high power at two accelerator test facilities at SLAC. The systems produced a 200 MW pulse with a near-perfect flat-top with pulse widths ranging from 150{endash}245 ns. In this paper we describe the design and test results of a rectangular-to-circular mode converter and the components/transmission systems based on them, as well as the design and measurements of the high power pulse compression systems using SLED-II. We will also describe how these components are being used to efficiently provide high power rf in the NLC Test Accelerator (NLCTA) program at SLAC. {copyright} {ital 1997 American Institute of Physics.}

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

SciTech Connect

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

Beyond Sound Bites and News Quotes: NSIDC's Arctic Sea Ice and News Analysis Web blog and Scientific Uncertainty  

NASA Astrophysics Data System (ADS)

The public, the media, and policymakers often turn to scientists for definite answers about Earth's changing climate. Researchers, in turn, offer observations with the caveat that there is always an amount of uncertainty in the data and the analysis. More or better data could modify trends. Random processes in Earth's most complex systems, like clouds, could contradict current theories about how they evolve and develop into weather systems that could put lives in danger. Often, these careful answers are reduced to a soundbite in TV or a quote in a newspaper report, and the public gets an answer, but the message of scientific uncertainty is almost always omitted. Arctic sea ice has long been recognized as a sensitive climate indicator, and has undergone a dramatic decline over the past thirty years. The National Snow and Ice Data Center has evolved into a top source for sea ice data and analysis. How does NSIDC respond to increasing questions about Arctic sea ice and climate and how does it communicate scientific uncertainty? This poster examines the ways that NSIDC's Arctic Sea Ice News and Analysis (ASINA) Web blog offers the public a transparent view of sea ice analysis, with discussions in scientific uncertainty that are lost in news reportage. It highlights the Web blog's interactive sea ice graph called ChArctic, which the pubic can use to explore sea ice data by year and make their own observations. It also discusses issues around the replacement of NSIDC's 20-year baseline with a new 30-year baseline for analyzing sea ice.

In this reply to criticisms of Michaels' and Stooksbury's paper, Michaels discusses several points which had not been emphasized in the manuscript. The salient points discussed in this reply include: (1) the importance of estimating the transient response to a gradually increasing greenhouse enhancement, and (2) the role of anthropogenically generated aerosols on canceling some warming, especially those that serve as cloud condensation nuclei. Michaels describes how a general circulation model would be ineffective for evaluating the effects of these factors on climate change, and thus would be in error in its assessment of the threat of global warming. 4 refs., 4 figs.

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

SciTech Connect

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

Recently, Valentini [Phys.

It is shown that this derivation is wrong and is based on a misinterpretation of the plasma sheath concept. {copyright} {ital 1996 American Institute of Physics.}

The energy of pions in nuclei as a function of momentum and density (and temperature) is an important ingredient, e.g., for pion production in heavy ion collisions. In spite of many efforts over the last 25 years one is not yet able to calculate reliably this dispersion relation from first principles. At the moment it seems best to use this relation determined by experiments (at least at lower energies and densities). {copyright} {ital 1997} {ital The American Physical Society}

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

SciTech Connect

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

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

SciTech Connect

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.

Dual annular rotating [open quotes]windowed[close quotes] nuclear reflector reactor control system  

DOEpatents

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.

State regulators go with the [open quotes]flow[close quotes  

SciTech Connect

Regulators must allow utilities to earn enough profit to attract capital. And because utilities are capital intensive, the issue of the appropriate allowance for return on common equity (ROE) is both vital and contentious. In the past, debate has focused primarily on technical questions involving the appropriate values for dividend yield and growth rate under the discounted cash flow (DCF) analysis that most regulators use to set the ROE rate component. A review of base-rate rulings at the state level over the past year, however, finds more and more utilities arguing that the DCF method itself is irreparably flawed. For example, Dr. William Avera, a utility witness in a recent Public Service Company of Colorado rate case, said that current capital markets are distorted as a result of the Federal Reserve Bank's attempts to ignite economic recovery by lowering short-term interest rates. He concluded that the DCF does not provide acceptable cost-of-equity estimates under the current economic conditions, because many of the indicated rates are not substantially higher than the yields on less risky capital investments, such as utility bonds. Dr. Avera also contended that DCF-calculated equity rates did not account for the additional market-structure risk that results from a utility's heavy reliance on purchased power as opposed to other resource options.

Guidelines for granting industrial {open_quotes}distress{close_quotes} rate discounts  

SciTech Connect

Increasingly seen are electric utilities offering discounted rates to targeted customers or classes to offset rising competition. These offers often come from utilities with surplus generating capacity and high industrial rates. With excess capacity, marginal costs fall below rates, allowing the utility to profit by offering discounts for incremental sales. Today, utilities in twenty states offer discounts; with this number likely to increase as regulation evolves towards price caps and flexible pricing. Rate discounts usually fall into three categories: load retention, economic development, or cogeneration deferral. Load retention discounts are often given to industries who are in economic distress, but this distress is often difficult for the utility to determine. Given are several strategic alternatives for utility discounts; including weighing the electric intensity of the industry, the length of the discount, revenue guarantees, and revenue sharing.

{open_quotes}High magnetic fields in the USA{close_quotes}  

SciTech Connect

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.

Artificial barriers to control excessive frac height growth [open quotes]Bracketfrac[close quotes  

SciTech Connect

The Garfield and Beaver Creek fields produce from several dolomite layers in the Devonian Richland formation at depths of 4200-4600 ft. The Richfield is a series of relatively thin, 4-20 ft dolomite reservoirs, which are confined above and below by anhydrites. These anhydrites are comparable to the dolomite reservoirs in fracture resistance and essentially do not present an effective stress barrier to fracture growth. The dolomite zones have a porosity range of 12-20%, and permeability ranges from 6-20 md. The dolomite reservoirs also contain significant amounts of free salt, which is apparent in the large quantities of produced salt in new wells. There are eight producing zones, oil gravity is 43[degrees] APi, and viscosity is 1 cp at the reservoir with a temperature of 110[degrees]F. Previous completions in the Richfield have been plagued by unrestricted fractured height growth because there is no control over where the frac is going. Standard practice has been to perforate and treat the zones in groups. If all zones are opened at the same time, communication usually occurs (up or down) during the fracturing of any group of zones. Artificial barriers to control excessive frac height growth were used in the Richfield formation for the stated reasons. Because no barrier was present between producing zones, the production capabilities of each zone and each new and existing well in the field were limited. INVERTAFRAC and DIVERTAFRAC services are techniques developed and used exclusively by Dowell Oilfield Service Company to control vertical fracture height. When both services are simultaneously used, the treatment is called BRACKETFRAC. By limiting fracture height to the pay zone, several important results are achieved: diversion from barren zones, water, or other undesirable fluids; improved fracture efficiency; deeper penetrating fractures; improved proppant distribution; and consistently better stimulation results.

[open quotes]Dimerization[close quotes] of the [Co[sub 2][sup III](OH)[sub 2  

SciTech Connect

Intense effort is currently directed toward elucidating the structure and mode of action of the Mn[sub 4] aggregate responsible for photosynthetic water oxidation in green plants and cyanobacteria. The arrangement of the metal ions at any of the oxidation levels (S[sub n] states; n =-1 to 4) of this water oxidation center (WOC) is currently unclear. We have extended our WOC modeling studies to encompass Co. The reasoning is that we may obtain Co[sup III] systems that are structurally analogous to, but more stable than, the Mn[sup III]/Mn[sup IV] species present at the highest S[sub n] states or that are intermediates in the O[sub 2] evolution process. For example, Co[sup III] and Mn[sub IV] both favor octahedral geometry and have similar effective ionic radii. Thus, it is a possibility that stable Co[sup III][sub 4] complexes could be structurally analogous to unstable Mn[sup IV][sub 4] complexes at higher S[sub n] states and could thus provide insights into the latter. Similarly, Co[sup III] is known to form stable peroxide complexes, whereas Mn[sub 4]O[sub 2][sup 2] species thought to be formed on oxidation of S[sub 3] are not observed, and only O[sub 2] and regenerated S[sub 0] are found. We herein describe our initial successes in this area, the preparation of Co[sub 2], Co[sub 3], and Co[sub 4] complexes. The Co[sub 3] and Co[sub 4] species possess the first examples of [Co[sub 3]([mu][sub 3]-O)([mu]-OH)[sub 3

Construction and analysis of a panel of {open_quotes}whole genome{close_quotes} radiation hybrids  

SciTech Connect

In an effort to generate a single panel of radiation hybrid cell lines that can be used to construct a radiation hybrid map of the entire human genome, we have fused diploid male human lymphoblastoid cells exposed to 8000 rad of X-rays with unirradiated Chinese hamster cells deficient for the enzyme thymidine kinase (TK), and selected for radiation hybrids in the presence of HAT selective medium. Genomic DNA isolated from each of 85 independent hybrids was assayed in duplicate for the presence of 100 STSs representing at least two STSs from each of the 23 human chromosomes. The retention frequency of individual markers was found to vary from 5% to 58%, with an average retention of 17%. In addition, each radiation hybrid was scored for the retention of 85 STSs derived from a 25 Mb region of the proximal short arm of chromosome 4. An algorithm developed specifically for use with diploid radiation hybrid data was used to construct a map. Our results indicate that this set of diploid radiation hybrids can be used to construct a radiation hybrid map of the entire human genome at an average resolution of approximately 500kb.

Comments on [open quotes]Global warming: A reduced threat [close quotes] by P. J. Michaels and D. E. Stooksbury  

SciTech Connect

The author of this letter criticizes Michaels and Stooksbury (1992) for arguing that, because climate models predict more warming for the last century than has been observed, the model predictions of major greenhouse warming must be wrong. It is the position of the author that this is not a valid argument, although the warming may have been relatively mild. In this letter, the author defends the belief that the magnitude of the recent warming actually tells very little about the sensitivity of the climate system to greenhouse gas emissions. Reasons for the warming observed over the last hundred years are summarized. 4 refs.

Incidence and origin of [open quotes]Null[close quotes] alleles in the (AC)n microsatellite markers  

SciTech Connect

Twenty-three (AC)n repeat markers from chromosome 16 were typed in the parents of the 40 CEPH (Centre d'Etude du Polymorphisme Humain) families. Where parents were informative, the entire families were then typed. There were seven markers in which null alleles were demonstrated, as recognized by the apparent noninheritance, by a sib, of a parental allele. Four of these markers showed a null allele in a single sibship, while in the other three at least 30% of the CEPH sibships were shown to have a null allele segregating. One null allele was sequenced and shown to be the result of an 8-bp deletion occurring within the priming sequence for PCR amplification of the (AC)n repeats. In gene mapping or in application to diagnosis, the presence of a segregating null allele will not corrupt the linkage data but could result in loss of information. In isolated instances a segregating null allele may be interpreted as nonpaternity. The presence of a null allele may generate misleading data when individuals are haplotyped to determine the presence of linkage disequilibrium with a disease gene. 10 refs., 2 figs., 1 tab.

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.

Giant fields of the late 80s associated with type [open quotes]A[close quotes] subduction in South America  

SciTech Connect

About 10 billion bbl of recoverable oil have been found in these three fields for which the petroleum generating subsystem is very similar. The potential source rocks are the organic sediments associated with the major downlap surface of the post-Pangea continental encroachment sedimentary cycle, i.e., MFS 91, 5 Ma (La Luna formation). However, the concentrating physico-chemical petroleum subsystem is quite different. The El Furrial/Musipan field is associated with a Tertiary foredeep basin overlying a generating Atlantic type passive margin. On the other hand, Cusiana and Ceuta fields are associated with a Tertiary foredeep basin developed over a generating back-arc basin. The different stacking of sedimentary basins controls the migration/entrapment petroleum subsystem. In El Furrial/Musipan, decollement surfaces and their associated thrusts are predominant whereas, in Ceuta and Cusiana the majority of compressional structures are created by tectonic inversions. These tectonic settings create different petroleum systems: (a) supercharged with low impedance and lateral drainage in El Furrial/Musipan, (b) normally charged with high impedance and vertically drained in Ceuta and Cusiana area. Each case requires appropriated exploration approaches.

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

Near-real time infrared observations of acidic sulfates in /open quotes/clean/close quotes/ air at Mauna Loa, Hawaii  

SciTech Connect

Sulfuric acid and its partially or completely neutralized salts with ammonia are believed to result from the oxidation of sulfur dioxide in cloud water and in other heterogeneous media present in the atmosphere. Due to the natural abundance of ammonia and the ubiquitous presence of sulfur in the atmosphere, (NH/sub 4/)/sub 2/SO/sub 4/ is commonly the dominant chemical species in the ambient aerosol. The amounts of ammonium sulfates are expected to be very low in areas far removed from anthropogenic emissions of sulfur dioxide. The chemical composition of submicrometer aerosol particles was determined at the Mauna Loa Observatory (MLO) on Mauna Loa in Hawaii during an eight-day period in August 1986. The MLO site was selected for this measurement because it is the only ground-based aerosol observatory in the remote Pacific Ocean that allows extended sampling of aerosols in the free troposphere. Measurements were made using an attenuated total internal reflection (ATR) impactor system. The impactor collects size-fractionated submicrometer particles for analysis by ATR infrared spectroscopy. The collected samples were analyzed using an on-site Perkin Elmer dispersive infrared spectrophotometer. Infrared absorption spectra (4000 to 250 cm/sup /minus/1/) of the samples were obtained within minutes after the ATR substrates were removed from the impactor. Absorbances were measured for sulfate, nitrate, and ammonium. Acidic sulfate showed infrared absorbances at 600 cm/sup /minus/1/ and 1210 cm/sup /minus/1/ in addition. Results showed that ammonium sulfate was the dominant chemical species in the submicrometer particles. Over half of the nearly 40 samples collected showed an acidic sulfate component. Consecutive samples were found to change from completely neutralized ammonium sulfate to acidic ammonium sulfates in a two-hour time interval. 5 refs., 1 tab.

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.

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

SciTech Connect

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

The printing process was characterized for firing temperature print thickness, print direction, resistor geometry and encapsulant effect. Laser trimming was characterized by first finding an operating envelope and then selecting an operating point. The envelope was located by varying the trimming parameters and determining their acceptability to electrical and visual criteria. Samples from both the envelope and operating point were environmentally conditioned The conditioning included thermal shock temperature cycle, 1000-hour temperature aging, 1000-hour humidity aging, and a simulated gold/tin solder reflow.

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

SciTech Connect

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

Review of recent studies from central and eastern Europe associating respiratory health effects with high levels of exposure to {open_quotes}traditional{close_quotes} air pollutants  

SciTech Connect

The serious environmental problems caused by decades of Communist mismanagement of natural resources in countries of Central and Eastern Europe have been brought to light in recent years. All environmental media, including air, water, food, and soil have been burdened with toxic chemicals. Large segments of the population have been, and are now being exposed to air pollution levels exceeding guidelines established by western countries and by international health organizations. This review focuses on epidemiologic evidence regarding health effects of poor air quality in Central and Eastern Europe. It appears that short-term high levels of air pollutants (primarily particulates and SO{sub 2}) may increase mortality in sensitive parts of the population. Associations were also seen between air pollution levels and prevalence of respiratory diseases as well as lung function disturbances in adults and children. One study indicated that urban air pollution increased the risk of lung cancer. Several investigations pointed to strong interactions between risk factors. The poor scientific standard of the studies often makes it difficult to evaluate the findings. Several steps should be taken to develop environmental epidemiology in Central and Eastern Europe, including international collaboration in research projects and training. 30 refs., 1 fig., 11 tabs.

[2 + 2 + 2]Cycloadditions of alkynes to furans and thiophenes. A cobalt-mediated [open quotes]enol ether walk[close quotes  

SciTech Connect

Involvement of the 2,3-double bond of furan and thiophene in cycloadditions is relatively uncommon, usually limited to specific substrates or by special conditions. Our finding that indoles, pyrroles, imidazoles, and uracils can be activated by CpCo to undergo cocyclizations with alkynes suggested an extension of these efforts to the title heterocycles, in particular because the latter constitute new brackets for the degree of aromaticity (furan lowest, thiophene highest) that is subject to neutralization in these reactions and because the anticipated enol (thio)ether products exhibit potential synthetic utility. This study demonstrates that the cobalt-mediated [2 + 2 + 2] methodology can be extended to furans and thiophenes but that in these, and possibly generally in related heteroalkenes, the generation of potential dienylic leaving groups in the resulting CpCo diene product may cause rearrangements and that formal C-H activations may complicate the outcome of the reaction. The observation that the relatively highly aromatic thiophene nucleus functions as a cocyclization partner points the way to a number of even more challenging substrates in this process. 20 refs.

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

SciTech Connect

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

SciTech Connect

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

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

SciTech Connect

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

More than just great quotes: An introduction to the Canadian Tri-Council's qualitative requirements  

PubMed Central

Although at times misunderstood by the general research community, qualitative research has developed out of diverse, rich and complex philosophical traditions and theoretical paradigms. In the most recent Canadian Tri-Council policy statement on the ethical conduct of research involving humans, a chapter was devoted to a summary of methods and methodological requirements that characterize robust qualitative research, despite the diversity of approaches. To dispel common misperceptions about qualitative research and introduce the unfamiliar reader to these requirements, the work of a qualitative study on isoniazid preventive therapy for prophylaxis of tuberculosis published in AIDS is critiqued alongside each of the Tri-Councils nine requirements.

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

PubMed

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.

Position and collision point measurement system for Fermilab{close_quote}s interaction regions  

SciTech Connect

A higher resolution beam position monitor (BPM) system has been developed at FNAL to measure the transverse position of the beam at opposite ends of the Collision Hall. A secondary function is to measure the longitudinal location of the collision point. This system is called the Collision Point Monitor (CPM). The transverse positions are determined by software rectification and integration of a BPM signal obtained from a sampling oscilloscope. A difference over sum calculation of the A and B signals yields the position. The longitudinal location is obtained by measuring the difference in time between the proton and antiproton bunches at both ends of the Collision Hall. The downstream difference is then subtracted from the upstream difference and the result is multiplied by half the speed of light to yield the collision point error. {copyright} {ital 1997 American Institute of Physics.}

Click c@refully before you quote: citing internet-based sources.  

PubMed

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.

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

PubMed

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

Reflection of Transverse Waves in a Structure "Dielectric-Piezoelectric Semiconductor with Current&quot  

NASA Astrophysics Data System (ADS)

Reflection of a plane monochromatic transverse wave by the boundary of the acoustic contact of a dielectric with a hexagonal piezoelectric semiconductor in the presence of a longitudinal charge drift is treated in the small-signal approximation within the framework of the hydrodynamic description of a charge carrier plasma. A procedure of selecting the branches with allowance for the conversion of the quasi-acoustic mode (a refracted transverse wave) into plasma-acoustic disturbances, both in-leaking at the boundary or out-leaking from it, is proposed for the determination of the solution under the conditions of a supersonic drift and overcritical angles of incidence. Beyond the restrictions of Whites theory of ultrasonic wave propagation in piezoelectric semiconductors, it is demonstrated that this technique removes the defects of the solutions obtained earlier in the form of discontinuities in angular dependences of the modulus of the reflection coefficient of a transverse wave in the vicinity of the critical angle of incidence and leads to a solution that does not contain a resonance singularity of a polar type.

Mutation detection in large genes: Use of overlapping PCR fragments for {open_quotes}double{close_quotes}screening of the APC gene and a PCR modification to concatenate multiple exons  

SciTech Connect

We report developments of earlier work which demonstrated the suitability of PCR-cloning in the 5{prime} terminus of IacZ for the detection of frameshift and nonsense mutations of in APC, the gene which predisposes carriers to adenomatous polyposis coli and, ultimately, colon cancer. A test set of clinically diagnosed APC patients and their unaffected relatives is being used to test a combination of multiplex PCR of several overlapping segments of coding sequence and a lethal negative selection against in-frame, i.e., wild type, clones. This modification will balance the strigency of the negative selection with the low-level readthrough, frameshifting and/or re-initiation of mutant clones, such that high-level {beta}-galactosidase production results in death, while a low level allows discrimination between APC mutant insertions and insert-free vector transformants. The same patient base is also serving as a test set for a PCR-based cloning technique that allows the concatenation of two exons into a single synthetic fragment by skipping over the intervening intron, bypassing the need for single exon analysis or mRNA/cDNA preparation. This technique is based on the design of primers with homology to intron sequences immediately adjacent to the exon sequences of interest, maintaining the reading frame, and adjusting for in-frame termination codons by base-substitutions. The conditions necessary for the concatenation of a large number of exons in a two-step PCR protocol are under investigation. These methods have advantages over other rapid mutation-detection systems by being (1) capable of detecting previously unidentified mutations, (2) non gel-based and (3) non-radioactive.

Catalytic characterization of lithium aluminum oxides: Including a study of both the cation replacement chemistry and the structure of the [alpha]LiAlO[sub 2]/[open quotes]HAlO[sub 2][close quotes] system  

SciTech Connect

Cation replacement is a low temperature synthetic technique used to replace most of the lithium cations in [alpha]LiAlO[sub 2] with protons without significantly modifying the structure of the reactant. Lauric acid worked well as a proton source because it was capable of 90% replacement without significant dissolution of [alpha]LiAlO[sub 2]. High pressure CO[sub 2]/H[sub 2]O treatment of the cation replaced product resulted in the decomposition of the reactant to form boehmite and Li[sub 2]CO[sub 3]. The XRD characterization of a series of partially replaced samples from the [alpha]LiAlO[sub 2]/HAlO[sub 2] system was used to develop an understanding of the cation replacement mechanism. A two phase mechanism is proposed, which consists of particles with an outer shell of lithiated HAlO[sub 2] and an inner core of [alpha]LiAlO[sub 2] (for 0.0 < x < 0.90). A model for the structure of HAlO[sub 2] was developed to describe the location of the protons and the lithium cations. The 3,3-dimethyl-1-isomerization reaction did not detect any intrinsic acidity on HAlO[sub 2] and detected only small amounts on calcined HAlO[sub 2] at 350[degrees]C. Lithium free [gamma]-alumina was extremely active for 3,3-dimethyl-1-butene isomerization demonstrating that the small concentration of lithium in both HAlO[sub 2] and calcined HAlO[sub 2] is sufficient to neutralize strong acid sites. The conversion of isopropyl alcohol produces propylene on acid-base sites and acetone on basic sites. [alpha]LiAlO[sub 2], [gamma]LiAlO[sub 2], and calcined HAlO[sub 2], produced varying amounts of propylene and acetone. [alpha]LiAlO[sub 2] and calcined HAlO[sub 2] produced a C6 diene, which indicates the presence of basic sites stronger than those needed for acetone formation. [alpha]LiAlO[sub 2] was the only sample that produced 4-methyl-2-pentanone and 4-methyl-2-pentanol.

A familial {open_quotes}balanced{close_quotes} 3;9 translocation with cryptic 8q insertion leading to deletion and duplication of 9p23 loci in siblings  

SciTech Connect

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.

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.

Modeling a one-dimensional bremsstrahlung and neutron imaging array for use on Sandia{close_quote}s Z machine  

SciTech Connect

Inertial confinement fusion is being studied on the Z facility at Sandia National Laboratories. Z is a large {ital z}-pinch machine which can provide 20 MA of current to {ital z}-pinch loads producing {approximately}1.8 MJ of soft x rays in less than 10 ns. Within the pinch region, decelerated electrons produce a strong source of bremsstrahlung radiation which varies from shot to shot. Additionally, a variety of inertial confinement fusion targets may produce fusion neutrons, the intensity and distribution of which depend on the temperature and density of the pinch. In this article, we describe the computer modeling behind the shielding design of a simple time-resolved, one-dimensional imaging array. This diagnostic will provide a time history for both the bremsstrahlung and neutron production as a function of height in the target. Calculations show that by building an array of scintillator fibers separated by long, thin tungsten collimator plates, a sampling rate of 0.254 mm at the target can be achieved. The corresponding channel-to-channel discrimination for such a design is shown to be better than 1000&as;1 for {lt}4 MeV photons and 100&as;1 for 2.45 MeV neutrons. By coupling scintillator fibers to a fiber-optic streak camera system, the system time response is expected to be dominated by the scintillator response ({approximately}1.2 ns). {copyright} {ital 1999 American Institute of Physics.}

The discovery of the {ital b} quark at Fermilab in 1977: The experiment coordinator{close_quote}s story

I present the history of the discovery of the Upsilon ({Upsilon}) particle (the first member of the {ital b}-quark family to be observed) at Fermilab in 1977 by the CFS (Columbia-Fermilab-Stony Brook collaboration) E288 experiment headed by Leon Lederman. We found the first evidence of the {Upsilon} in November 1976 in an early phase of E288. The subsequent discovery in the spring of 1977 resulted from an upgraded E288{emdash}the {mu}{mu}II phase, optimized for dimuons, with about 100 times the sensitivity of the previous investigatory dimuon phase (which had been optimized for dielectrons). The events leading to the discovery, the planning of {mu}{mu}II and the running, including a misadventure (the infamous Shunt Fire of May 1977), are described. Some discussions of the aftermath, a summary, and an acknowledgment list end this brief historical note. {copyright} {ital 1998 American Institute of Physics.}

Frequency analysis of tick quotes on the foreign exchange market and agent-based modeling: A spectral distance approach  

NASA Astrophysics Data System (ADS)

High-frequency financial data of the foreign exchange market (EUR/CHF, EUR/GBP, EUR/JPY, EUR/NOK, EUR/SEK, EUR/USD, NZD/USD, USD/CAD, USD/CHF, USD/JPY, USD/NOK, and USD/SEK) are analyzed by utilizing the Kullback-Leibler divergence between two normalized spectrograms of the tick frequency and the generalized Jensen-Shannon divergence among them. The temporal structure variations of the similarity between currency pairs is detected and characterized. A simple agent-based model in which N market participants exchange M currency pairs is proposed. The equation for the tick frequency is approximately derived theoretically. Based on the analysis of this model, the spectral distance of the tick frequency is associated with the similarity of the behavior (perception and decision) of the market participants in exchanging these currency pairs.

Three metaphors and a (mis)quote: thinking about staffing-outcomes research, health policy and the future of nursing.  

PubMed

Conducting research on nurse staffing and outcomes is very challenging, and the application of staffing-outcomes research in practice is both fraught with controversy and vitally important for the safety of our patients and the future of the profession. As I stand back and think about being involved in staffing-outcomes research for nearly a decade and sharing many of my thoughts about this rapidly growing literature in reviews and commentaries in print, certain metaphors for trends in this field come to mind. I won't claim originality for the insights that follow or attempt to thoroughly trace the genealogy of the stories and metaphors here, but offer them to provide what I hope is a fresh perspective to material that I and many of my colleagues have visited and revisited on numerous occasions.

Measurement of the photon field, {ital E}{gt}150thinspeV on Sandia{close_quote}s Z Facility  

SciTech Connect

The Z Facility at Sandia National Laboratories utilizes {ital z}-pinch implosions to produce up to 2 MJ of x rays. On Z, bremsstrahlung radiation is produced in various parts of the machine as a product of both power flow electrons and those accelerated in the pinch region. An understanding of the energy spectra and intensity of this radiation is important to both the explanation of the {ital z}-pinch physics and the design of new diagnostics. A technique has been developed using a differential absorption spectrometer to measure the photon field for energies greater that 150 eV for bremsstrahlung from the {ital z}-pinch or the vacuum transmission lines. This article describes the techniques and results used to date. {copyright} {ital 1999 American Institute of Physics.}

Penetrance estimates for BRCA1 and BRCA2 based on genetic testing in a Clinical Cancer Genetics service setting: Risks of breast/ovarian cancer quoted should reflect the cancer burden in the family  

PubMed Central

Background The identification of a BRCA1 or BRCA2 mutation in familial breast cancer kindreds allows genetic testing of at risk relatives. However, considerable controversy exists regarding the cancer risks in women who test positive for the family mutation. Methods We reviewed 385 unrelated families (223 with BRCA1 and 162 with BRCA2 mutations) ascertained through two regional cancer genetics services. We estimated the penetrance for both breast and ovarian cancer in female mutation carriers (904 proven mutation carriers 1442 females in total assumed to carry the mutation) and also assessed the effect on penetrance of mutation position and birth cohort. Results Breast cancer penetrance to 70 and to 80 years was 68% (95%CI 64.771.3%) and 79.5% (95%CI 75.583.5%) respectively for BRCA1 and 75% (95%CI 71.778.3%) and 88% (95%CI 85.391.7%) for BRCA2. Ovarian cancer risk to 70 and to 80 years was 60% (95%CI 6571%) and 65% (95%CI 7584%) for BRCA1 and 30% (95%CI 25.534.5%) and 37% (95%CI 31.542.5%) for BRCA2. These risks were borne out by a prospective study of cancer in the families and genetic testing of unaffected relatives. We also found evidence of a strong cohort effect with women born after 1940 having a cumulative risk of 22% for breast cancer by 40 years of age compared to 8% in women born before 1930 (p = 0.0005). Conclusion In high-risk families, selected in a genetics service setting, women who test positive for the familial BRCA1/BRCA2 mutation are likely to have cumulative breast cancer risks in keeping with the estimates obtained originally from large families. This is particularly true for women born after 1940.

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

PubMed

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

Rethinking ALARA  

SciTech Connect

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.

Comparative assessment of standards development for radiation and other hazardous exposures

A fundamental question in development of standards for allowable exposure is, {open_quotes}What levels of safety are the standards intended to achieve?{close_quotes} This question has clearly not received the attention it deserves. A comparative assessment of standards for radiation and other physical and chemical hazards indicates that differing concerns may have motivated their developmental process. In most cases, the organization formulating the standards stated their objective in general terms such as, {open_quotes}to ensure safety,{close_quotes} {open_quotes}to protect worker`s health,{close_quotes} {open_quotes}to cause no undue stress,{close_quotes} {open_quotes}to avoid adverse health effects,{close_quotes} or to {open_quotes}maintain exposure levels as low as reasonably achievable.{close_quotes} It was generally recognized that absolute safety was unachievable, and therefore, some {open_quotes}reasonable{close_quotes} level of safety would need to be determined. The problem is made even more complex with the understanding that there can be a wide range in individual sensitivity to various harmful agents.

The name tungsten, derived from the Swedish words {open_quotes}tung{close_quotes} and {open_quotes}sten{close_quotes}, meaning heavy stone, was first applied to a tungsten-containing mineral in 1755. The mineral, itself, was subsequently identified by C.W. Scheele in 1781, and named scheelite. Metallic tungsten was first isolated from the mineral wolframite in 1783, and given the German name {open_quotes}wolfram,{close_quotes} which remains an alternative name for the element. Ultimately, the English word, tungsten, became the official name, while W remains the element`s chemical symbol.

Icosahedral quasicrystal decoration models. II. Optimization under realistic Al-Mn potentials

We have constructed and relaxed over 200 different finite structure models for the quasicrystal {ital i}-AlMn based on decorations of the {open_quote}{open_quote}canonical-cell tiling.{close_quote}{close_quote} We adopted {ital ab} {ital initio}-based pair potentials with strong Friedel oscillations, which reproduce the phase diagram of real Al-Mn intermetallic crystal structures fairly well. 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.

Flute perturbations in a plasma with {open_quotes}hot{close_quotes} are considered. Steady-state solutions are found which describe localized vortex structures. Two types of vortex solutions are considered: a dipolar vortex and a combination of a dipolar and a monopolar vortex. It is shown that the presence of {open_quotes}hot{close_quotes} particles has an effect on the region in which the vortex solutions exist in

Second generation interferometry measurements at CERN  

SciTech Connect

Source size parameters measured via two-particle interferometry in experiment NA44 for 200 GeV/nucleon S+Pb collisions are compared to calculations using the RQMD event generator. Reasonable agreement is found in most cases. The event generator is then used to compare the {open_quotes}true{close_quotes} size of the particle-emitting source to the measured size parameters and to discuss the difficulties in defining the {open_quotes}true{close_quotes} source size.

Production of polar cap electron density patches by transient magnetopause reconnection  

SciTech Connect

Some implications are considered of recent theoretical work concerning the excitation of dayside ionospheric convection by magnetic reconnection at the dayside magnetopause. In particular, transient bursts of such reconnection ([open quote]flux transfer events[close quote]) are considered as a cause of polar cap [open quote]patches[close quote] of enhanced plasma density. Examples of such patches, as observed at European longitudes by the EISCAT radar, are presented and used to discuss the implications of the proposed mechanism.

Array enhanced stochastic resonance: Implications for signal processing  

SciTech Connect

In computer simulations, we enhance the response of a {open_quote}{open_quote}stochastic resonator{close_quote}{close_quote} by coupling it into an array of identical resonators. We relate this array enhanced stochastic resonance (AESR) to the global spatiotemporal dynamics of the array and show how noise and coupling cooperate to organize spatial order, temporal periodicity, and peak output signal-to-noise ratio. We consider the application of AESR to signal processing. {copyright} {ital 1996 American Institute of Physics.}

Logic of likelihood  

SciTech Connect

The notion of {open_quotes}probability{close_quotes} is generalized to that of {open_quotes}likelihood,{close_quotes} and a natural logical structure is shown to exist for any physical theory which predicts likelihoods. Two physically based axioms are given for this logical structure to form an orthomodular poset, with an order-determining set of states. The results strengthen the basis of the quantum logic approach to axiomatic quantum theory. 25 refs.

Fissile material smuggling: German politics, hype and reality  

SciTech Connect

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}

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

SciTech Connect

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

A dual, parallel cavity Fabry-Perot interferometer  

SciTech Connect

Laser Doppler shift velocimetry operating in the fringe mode is widely used to record the velocity history of optically reflective solid objects. When the object is rapidly accelerated, the time resolution of the Fabry-Perot Interferometer (FPI)/streak camera system is frequently inadequate to unambiguously record the data. That is, there is a {open_quotes}dead time{close_quotes} during which fringes form and expand without producing a resolvable record. To remedy this, we have developed a dual, parallel cavity FPI which produces two sets of fringes at the slit of the recording streak camera. The input mirror of the FPI is a conventional flat while the output mirror is stepped so there are two mirror spacings. The input light is divided by the respective areas of the stepped mirror to form two sets of fringes; a higher quality set of fringes {open_quotes}A{close_quotes} is used to determine the velocity history while a second set of fringes {open_quotes}B{close_quotes} is used as a {open_quotes}referee{close_quotes} to determine the number of fringe jumps during the {open_quotes}dead time.{close_quotes} Since the two sets of fringes are necessarily interleaved, there is a possibility of fringe overlap, i.e., fringes of set A can spatially overlap fringes of set B. To date, two dual cavity FPI`s have been successfully constructed and characterized. The theory of operation, details of construction, and the results are described.

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

SciTech Connect

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

Selection criteria for adding management units to the SAMAB regional biosphere reserve  

SciTech Connect

The SAMAB (Southern Appalachian Man and the Biosphere) regional biosphere reserve initially consisted of three land management units in the southern Appalachians (Great Smoky Mountains National Park, Coweeta Hydrologic Laboratory, and Oak Ridge National Laboratory's National Environmental Research Park). Traditional biosphere reserves in UNESCOs Man and the Biosphere (MAB) program have been defined by [open quote]core[close quote], [open quote]buffer[close quote], and [open quote]transition[close quote] zones. These concepts are difficult to apply to regional biosphere reserves. Therefore, selection criteria for incorporating additional land management units into SAMAB were developed which recognize 4 components of the regional reserve: biosphere reserve (core) units, varied and harmonious landscapes, modified landscapes, and the zone of cooperation. Selection criteria define ecological, political, logistic, and educational requirements for inclusion. The Tennessee River Gorge Trust is currently under evaluation for inclusion in SAMAB.

Hydrocode analysis of the data was performed to gain understanding of the {open_quotes}plateau{close_quotes} features in the data. Analyses using conventional strength models were not satisfactory due to the very high strain rates of these experiments (strain rates on the order of 10{sup 10}/s). Calculations using the PTW strength model rate dependence (2) gave very accurate reproduction of the experimental results, and allowed computational examination of the {open_quotes}data plateaus.{close_quotes} These results show that the {open_quotes}data plateaus{close_quotes} may be due to strain-rate effects and experimental variation in the data. {copyright} {ital 1996 American Institute of Physics.}

Use of SSH on a compartmented mode workstation  

SciTech Connect

SSH stands for {open_quotes}Secure Shell.{close_quotes} It is now a user shell like csh or ksh. Instead it is a widely-used means to accomplish secure, encrypted communication among cooperating nodes. It is a secure replacement for the {open_quotes}r-commands{close_quotes}, rlogin, and rcp. SSH is free for noncommercial use and builds and runs on most any Unix platform. A Compartmented Mode Workstation (CMW) is an example of a secure or {open_quotes}trusted{close_quotes} operating system. The use of SSH on a CMW introduces security problems unless the SSH source code is modified to take advantage of the security features of the CMW. This paper describes the port and use of SSH on one particular brand of CMW.

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

SciTech Connect

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

Hazardous waste facilities and environmental equity: A proposed siting model  

SciTech Connect

The standard of living of all Americans is enhanced by industrial and economic expansion. At the same time, economic and industrial growth results in the generation, consumption and release of tons of toxic chemicals each year. Many manufacturing processes generate hazardous wastes. There are two categories of hazardous waste. The first category includes wastes that {open_quotes}can cause or significantly contribute{close_quotes} to death or serious irreversible or incapacitating illness on account of {open_quotes}quantity, concentration, or physical, chemical, or infectious characteristics;{close_quotes} the second encompasses wastes that pose a substantial or potential danger {open_quotes}to human health or the environment{close_quotes} when mismanaged.

Structural analysis of a superconducting central solenoid for the Tokamak Physics Experiment  

SciTech Connect

The Tokamak Physics Experiment (TPX) concept design uses superconducting coils to accomplish magnetic confinement. The central solenoid (CS) magnet is divided vertically into 8 equal segments which are powered independently. The eddy current heating from the pulsed operation is too high for a case type construction; therefore, a {open_quotes}no case{close_quotes} design has been chosen. This {open_quotes}no case{close_quotes} design uses the conductor conduit as the primary structure and the electrical insulation as a structural adhesive. This electrical insulation is the {open_quotes}weak link{close_quotes} in the coil winding pack structure and needs to be modeled in detail.

Large order dimensional perturbation theory: A new approach  

SciTech Connect

Dimensional perturbation theory offers much insight into the dynamics of atomic and molecular systems and is a powerful calculational tool yielding very accurate energies. 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. Large order dimensional perturbation expansions for the energy have been developed using the moment method. However, the moment method has to be individually {open_quotes}tailored{close_quotes} to {open_quotes}fit{close_quotes} the state in question, does not readily give wavefunctions and is susceptible to round off error. We will report on a new method which provides wavefunctions directly, may be used to solve for any state without {open_quotes}alteration{close_quotes} and is not as tarnished b round off error.

Icosahedral quasicrystal decoration models. I. Geometrical principles  

SciTech Connect

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.}

Toxicity evaluation and hazard review for Rigid Foam  

SciTech Connect

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

Specification and acceptance in nondestructive testing  

SciTech Connect

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

Fundamental threshold of chaos in some nonlinear oscillators  

SciTech Connect

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.}

Russia`s nuke complex: A case for downsizing

Nuclear weapons stored in former Soviet republics, uncontrolled export of bomb-grade nuclear materials, and recruitment of ex-Soviet nuclear physicists by Third-World nations remain today`s top proliferation risks, reports Oleg Bukharin, a visiting researcher at Princeton University`s Center for Energy and Environment Studies. To address these risks, Russia {open_quotes}must shift its weapons production and development to weapons dismantlement, management of weapons materials, and maintenance of a much smaller...arsenal,{close_quotes} Bukharin writes. The goal of such conversion, he says, {open_quotes}is a nuclear complex that is environmentally safe...and compatible with nonproliferation objectives.{close_quotes} Reconfiguration of Russia`s weapons complex also must provide for redeployment of the hundreds of thousands of scientists, engineers, and technicians who have supported the federation`s nuclear weapons program, Bukharin insists. {open_quotes}A truly durable strategy to prevent the dispersion of Russian weapons expertise must [involve] these weapons experts in non-weapons research,{close_quotes} says Bukharin.

Green remediation: Using plants to clean the soil  

SciTech Connect

Rufus Chaney has his eye on plants with a lusty appetite for toxic heavy materials. Chaney foresees a day when these remarkable plants will be used to clean contaminated soils at smelter and mining sites, landfills, nuclear waste dumps, farmland, or at any urban or rural site contaminated with lead, cadmium, zinc, nickel, or radioactive isotopes such as uranium or cobalt. The plants would take up the toxic metals or isotopes through their roots and transport them to stems or leaves where they could be easily removed by harvesting. A U.S. Department of AGriculture agronomist, Chaney says the cost of using plants to clean polluted soil {open_quotes}could be less than one-tenth the price tag for either digging up and trucking the soil to a hazardous waste landfill or making it into concrete.{close_quotes} Chaney, a heavy-metals expert at USDA`s Agricultural Research Service Environmental Chemistry Laboratory in Beltsville, Maryland, says the cost could be further offset by recovering heavy metals from the plants and selling them. The metal-scavenging plants, called hyperaccumultors, would be grown and harvested like hay, Chaney says. {open_quotes}Burning the hay allows recovery and recycling of the metals. The ash is similar to commercial ore and could be sold as {open_quote}Bio-Ore{close_quote}.{close_quotes} Chaney calls the process {open_quotes}green remediation.{close_quotes} He says that without intervention, heavy metals stay in soil for centuries.

A quantum mechanical gauge model and a possible dynamical solution of the strong {ital CP} Problem  

SciTech Connect

A model describing a quantum mechanical particle on a circle with minimal electromagnetic interaction with a space independent vector potential, and with a potential {minus}{ital M}cos({var_phi}{minus}{theta}{sub {ital M}}) so that it mimics the massive Schwinger model, is discussed as a prototype of mechanisms and infrared structures which characterize gauge quantum field theories in positive gauges and QCD in particular. The functional integral representation in terms of the field variables which enter in the Lagrangean displays non-standard features, like a complex functional measure (failure of Nelson positivity), a crucial r{cflx o}le of the boundary conditions, and the decomposition into {theta} sectors already in finite volume. In the infinite volume limit, one essentially recovers the standard picture when {ital M}=0 ({open_quote}{open_quote}massless fermions{close_quote}{close_quote}), but one meets substantial differences for {ital M}{ne}0: for generic boundary conditions, independently of the Lagrangean angle of the topological term, the infinite volume limit selects the sector with {theta}={theta}{sub {ital M}} and provides a natural {open_quote}{open_quote}dynamical{close_quote}{close_quote} solution of the strong CP problem. In comparison with previous approaches, the strategy discussed here allows us to exploit the consequences of the {theta} dependence of the free energy density, with a unique minimum at {theta}={theta}{sub {ital M}}. {copyright} 1996 Academic Press, Inc.

Simple analytical methods for computing the gravity-wave contribution to the cosmic background radiation anisotropy  

SciTech Connect

We present two simple analytical methods for computing the gravity-wave contribution to the cosmic background radiation (CBR) anisotropy in inflationary models; one method uses a time-dependent transfer function, the other methods uses an approximate gravity-mode function which is a simple combination of the lowest order spherical Bessel functions. We compare the CBR anisotropy tensor multipole spectrum computed using our methods with the previous result of the highly accurate numerical method, the {open_quote}{open_quote}Boltzmann{close_quote}{close_quote} method. Our time-dependent transfer function is more accurate than the time-independent transfer function found by Turner, White, and Lindsey; however, we find that the transfer function method is only good for {ital l}{approx_lt}120. Using our approximate gravity-wave mode function, we obtain much better accuracy; the tensor multipole spectrum we find differs by less than 2{percent} for {ital l}{approx_lt}50, less than 10{percent} for {ital l}{approx_lt}120, and less than 20{percent} for {ital l}{le}300 from the {open_quote}{open_quote}Boltzmann{close_quote}{close_quote} result. Our approximate graviton mode function should be quite useful in studying tensor perturbations from inflationary models. {copyright} {ital 1996 The American Physical Society.}

Operational mode analysis of the maps NTP system

Within the framework of the french NTP program MAPS, the analysis of the (start-up/shut-down) transient sequences whose negative impact on the specific impulsion Isp is important, requires the evaluation of the hydrogen system performance and consequently the development of a simulation computer program. This work induces a preliminary evaluation of the hydrogen system performance under nominal operating conditions. A first approach of the transient operating mode has been simultaneously performed; more specifically the evolution of the core during a shut-down sequence has been studied in order to improve the residual power evacuation and optimize necessary hydrogen amounts for cooling. Furthermore the {open_quote}{open_quote}SIMAPS{close_quote}{close_quote} computer program based on the 3D thermohydraulic code {open_quote}{open_quote}FLICA 4{close_quote}{close_quote} is being developed to analyze transient process and its benchmarking under nominal conditions is under way.

The principles behind the ISO 9000 accreditation are based on the Total Quality Management (TQM) principles that are being implemented in many U.S. industries. This paper will deal only with the calibration issue. There is a difference in the areas covered by ISO 9000 and ISO Guide 25 documents. ISO 9000, in particular ISO 9001 - ISO 9003, cover the {open_quotes}calibration{close_quotes} of inspection, measuring and test equipment. This equipment is basically used for {open_quotes}factory calibrations{close_quotes} to determine that equipment is performing within manufacturer specifications. ISO Guide 25 is specifically for {open_quotes}calibration and testing laboratories,{close_quotes} generally laboratories that have painstaking procedures to reduce uncertainties and establish high accuracy of the transfer of calibration. The experience of the University of Wisconsin Accredited Dosimetry Calibration Laboratory in conforming to ISO Guide 25 will be outlined. The entire laboratory staff must become familiar with the process and an individual with direct authority must become the one to maintain the quality of equipment and calibrations in the role of {open_quotes}quality-assurance manager.{close_quotes}

Colliding beams in a M{umlt o}bius accelerator  

SciTech Connect

An accelerator can be called {open_quote}{open_quote}M{umlt o}bius{close_quote}{close_quote} if it contains a {open_quote}{open_quote}twist{close_quote}{close_quote} element that forces a particle to complete two traversals of the ring before returning to a corresponding state. The resultant ring has properties very different from an untwisted lattice. Since chromaticity correction needs only to be performed in one plane, it can be done entirely in the (easy) horizontal plane, with {pi}-separated, non-interleaved, sextupole pairs. This permits increased focusing strength while preserving large amplitude stability. In colliding beam operation, the (round) beams are robust against beam-beam interaction. Simulation indicates that beams counter-rotating in the same chamber need not be separated even for accumulated small-amplitude tune shifts greatly exceeding one. The large resulting tune spreads are found to stabilize the beams against head-tail instability with greater-than-typical head-tail tune shifts. Since stabilization relies at present on synchrotron oscillations with chromaticity near zero, the sextupoles needed for this, and the large-amplitude degradation they cause, may be superfluous. Stable operation is possible with beam-beam tune shifts well in excess of 0.1 at the main experiment crossing points. {copyright} {ital 1996 American Institute of Physics.}

What`s in a name? Chromosome 22q abnormalities and the DiGeorge, velocardiofacial and conotruncal anomalies face syndromes  

SciTech Connect

The recent advances in our understanding of the phenotype associated with deletion of the DiGeorge Chromosome Region (DGCR) at 22q11.2 are in many ways analogous to the fable about the blind men and the elephant. Originally described as three distinct phenotypes (DiGeorge (DG) syndrome, velocardiofacial (VCF) syndrome, and the conotruncal anomalies face (CTAF) syndrome), it is now clear that there is only a single broad and variable phenotype associated with deletion of the DGCR. As in the fable, distinguished clinicians approached this phenotypic {open_quotes}elephant{close_quotes} from different perspectives and provided three separate, although overlapping descriptions. Our analogy to this fable is not to imply some {open_quotes}blindness{close_quotes} on the part of these clinicians, but rather to point out the well-known difficulty in delineating the indistinct phenotypic boundaries of a syndrome until a genetic or biochemical marker for the condition is available. The recent availability of a fluorescent in situ hybridization (FISH) probe to detect deletion of the DGCR now allows delineation of the broad phenotype of our {open_quotes}elephant{close_quotes} which spans from lethal DG phenotypes through the intermediate VCF and CTAF phenotypes to the newly recognized {open_quotes}mild{close_quotes} phenotype consisting of only developmental delays and subtle facial abnormalities. 33 refs.

SciTech Connect

Pb/{ital I}/YBCO tunnel junctions have been fabricated on {open_quote}{open_quote}{ital ab} edge{close_quote}{close_quote} surfaces of YBCO single crystals (the {open_quote}{open_quote}{ital ab} edge{close_quote}{close_quote} surface is parallel to {ital c} axis and normal to {ital a} or {ital b} axis). The characteristics of these {ital ab} junctions were compared to those of {ital c}-axis junctions. In addition, STM studies were carried out on {ital c}-axis YBCO surfaces (studying exposed {ital ab} planes). We conclude from the combined results that the tunneling current in our previously studied {ital c}-axis junctions is along the {ital c} direction and is the result of {ital c}-axis coupling. {ital c}-axis Josephson coupling between a conventional superconductor and YBCO provides strong evidence for the existence of an {ital s}-wave component in the YBCO order parameter. {copyright} {ital 1996 The American Physical Society.}

Extreme variation between blood and fibroblast DNA patterns in mosaic fragile X males  

SciTech Connect

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.

Image accuracy and representational enhancement through low-level, multi-sensor integration techniques  

SciTech Connect

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

Tertiary tectonic in the Tehuantepec Isthmus, Mexico  

SciTech Connect

A microplate model in the basement was proposed according to photointerpretation of satellite imagery and supported with microtectonic studies in the Tehuantepec's Isthmus. The microplate is located in the northwestern part of the [open quotes]Sierra de Chiapas,[close quotes] and structurally has lineaments that correspond with sinestral wrench faults oriented northeast-southwest and dextral faults oriented northwest-southeast. In the front of the microplate, these faults are joined in an arc form. The microplate began its movement forward to the north in the middle Tertiary. This movement originated in a regional compressional stress that was younger to the north. The stress changed the orientation of the anticline axis from northwest-southeast to west-east. In its western limit, the stress produces a sinestral shear stress that built a rotational deformation in the [open quotes]Sierra Atravesada,[close quotes] and represents a superimposed tectonic block over an ancient (laramide) orogeny. This system has also produced other secondary transtensional effects oriented northwest-southeast, represented along the [open quotes]Depression Central del Istmo.[close quotes] The microplate has formed a tensional system opening the [open quotes]Superior, Inferior, and Mar Muerto[close quotes] lagoons. The microplate is strongly related with the relief, seismic activity, and the tectonics of the salt of the Tehuantepec's Isthmus.

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

SciTech Connect

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

Description and classification of uranium oxide hydrate sheet anion topologies  

SciTech Connect

The sheets of uranyl ions (U{sup 6+}O{sub 2}){sup 2+} in the structures of all uranyl oxide hydrates (UOH) (and the structurally related {alpha}- and {beta} forms of U{sub 3}O{sub 8}) are based on only four structural unit chains. Each sheet type may be reduced to its underlying sheet anion topology to determine the chains present within each topology and to describe the structural relationships among these phases. Each sheet type is described by a chain stacking sequence. The four chain types required to construct the UOH sheet anion topologies are the {bold H}-chains, the {bold R}-chain, the {bold P}-chain, and the directional {open_quotes} arrowhead{close_quotes} chains denoted by {bold U} and {bold D}. The {bold H}-chain is found only in the sheet anion topology of {alpha}-UO{sub 2}(OH){sub 2} and consists of hexagonal sites sharing opposing edges. In {alpha}-UO{sub 2}(OH){sub 2}, all hexagons are populated with uranyl ions. The {open_quotes} arrowhead{close_quotes} chain is composed of pentagonal sites populated with uranyl ions and sharing edges and alternating with vacant triangular sites. Arrowhead chains are present in the sheet anion topologies of all other UOH sheets. Arrowhead chains are directional and can occur in both {bold U} and {bold D} {open_quotes} senses{close_quotes} within a single anion topology. The {bold P}-chain consists of edge-sharing pentagonal sites populated with uranyl ions forming a zigzag chain. The {bold P}-chain is flanked on both sides by arrowhead chains of the same {open_quotes} sense{close_quotes}. The remaining structural unit is a discontinuous {open_quotes} chain{close_quotes} of rhombic sites. This {open_quotes}{bold R}-chain{close_quotes} is produced when nested; adjacent {bold U} and {bold D} {open_quotes} arrowhead{close_quotes} chains are translated diagonally. (Abstract Truncated)

The origin of large scale structure in mantle convection: effects of plate motions and viscosity stratification  

SciTech Connect

Convection in Earth{close_quote}s mantle is dominated by long-wavelength structure, as evidenced by the very {open_quote}{open_quote}red{close_quote}{close_quote} spectra of both seismic velocity heterogeneity in the deep mantle and the non-hydrostatic gravity field, or geoid. Here we show that this large-scale structure may be a consequence of two factors that influence the scale of mantle convection. First, the existence of surface plates, which tend to organize the flow. Second, a substantial increase in lower mantle viscosity for which there is considerable independent geophysical evidence. Combining these two factors in 3-D spherical mantle convection models explains rather well the observed seismic spectrum of mantle heterogeneity. {copyright} American Geophysical Union 1996
