    1996-12-31

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

  3. Search for open-quote open-quote polarized close-quote close-quote instantons in the vacuum

    International Nuclear Information System (INIS)

    Kuchiev, M.Y.

    1996-01-01

    The new phase of a gauge theory in which the instantons are open-quote open-quote polarized,close-quote close-quote i.e., have the preferred orientation, is discussed. A class of gauge theories with the specific condensates of the scalar fields is considered. In these models there exists an interaction between instantons resulting from one-fermion loop corrections. The interaction makes the identical orientation of instantons the most probable, permitting one to expect the system to undergo a phase transition into the state with polarized instantons. The existence of this phase is confirmed in the mean-field approximation in which there is a first-order phase transition separating the open-quote open-quote polarized phase close-quote close-quote from the usual nonpolarized one. The considered phase can be important for the description of gravity in the framework of the gauge field theory. copyright 1996 The American Physical Society

    1993-01-01

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

    A mesoscopic superposition of quantum states involving radiation fields with classically distinct phases was created and its progressive decoherence observed. The experiment involved Rydberg atoms interacting one at a time with a few photon coherent fields trapped in a high Q microwave cavity.

    1995-01-01

    During the past few years, open-quotes hot spotsclose quotes due to the presence of particles of metal activated during their migration through the reactor core, have been detected at several French pressurized water reactor (PWR) units. These open-quotes hot spots,close quotes which generate very high dose rates (from about 10 Gy/h to 200 G/h) are a significant factor in increase occupational exposures during outrates. Of particular concern are the difficult cases which prolong outage duration and increase the volume of radiological waste. Confronted with this situation, Electricite de France (EDF) has set up a national research group, as part of its ALARA program, to establish procedures and techniques to avoid, detect, and eliminate of hot spots. In particular, specific processes have been developed to eliminate these hot spots which are most costly in terms of occupational exposure due to the need for reactor maintenance. This paper sets out the general approach adopted at EDF so far to cope with the problem of hot spots, illustrated by experience at Blayais 3 and 4

    There can be little doubt that downsizing is one of the major events occurring at every company in America. If your company has not begun this effort, you can believe it, that it is only a matter of time. At Duke Power Company, this effort began in earnest in 1988. Since then, the changes have been considerable in the Chemistry department at McGuire, and especially significant in the Radwaste department. This paper will discuss the benefits and the problems that we have encountered, as well as the steps that we took, good and bad, to meet the challenges that we faced. Some of the processes that we used have worked out very well. Some have been very disappointing. Still others are in an indeterminate state. Time will tell if we have truly open-quotes copedclose quotes

  15. Myth-building: The open-quotes Islamicclose quotes bomb

    International Nuclear Information System (INIS)

    Hoodbhoy, P.

    1993-01-01

    The open-quotes Islamic Bombclose quotes is roughly understood to be a nuclear weapon aquired for broad ideological reasons--a weapon that supposedly belongs to the Muslim 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 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

  16. A open-quotes zero wasteclose quotes coolant management strategy

    International Nuclear Information System (INIS)

    Kennicott, M.A.

    1994-01-01

    In June of 1992 the Waste Minimization Program at Rocky Flats Plant (RFP) began a study to determine the best methods of managing water-based industrial metalworking fluids in the plant's Tool Manufacturing Shop. The shop was faced with the challenge of managing fluids that could no longer be disposed of in the traditional manner, through the plant's liquid process waste drains, due to a problem they, were having causing in the Liquid Waste Operations Evaporator. The study's goal was to reduce the waste coolants being generated and to reduce worker exposure to a serious health risk. Results of this study and those of a subsequent study to determine relative compatibilities of various coolants and metals, led to the application of a open-quotes zero wasteclose quotes machine coolant management program. This program is currently saving the generation of 10,000 gallons of liquid waste annually, has eliminated worker exposure to harmful bacteria and biocides, and should result in extended machine tool life, increased product quality, fewer rejected parts, and decreases labor costs

  18. The physics of open-quotes vacuumclose quotes breakdown

    International Nuclear Information System (INIS)

    Schwirzke, F.; Hallal, M.P. Jr.; Maruyama, X.K.

    1993-01-01

    The initial plasma formation on the surface of a cathode of a vacuum diode, vacuum arc, and many other discharges is highly non-uniform. Micron-sized cathode spots form within nanoseconds. Despite the fundamental importance of cathode spots for the breakdown process, their structure, and the source of the required high energy density were not well understood. When an increasing voltage is applied, enhanced field emission of electrons begins from a growing number of small spots or whiskers. This and the impact of ions stimulate desorption of weakly bound adsorbates from the surface of a whisker. The cross section for ionization of the neutrals has a maximum for ∼ 100 eV electrons. As the diode voltage increases, the 100 V equipotential surface which moves towards the cathode is met by the desorbed neutrals moving away from the cathode. These two regions proceed from no overlap to a significant amount of overlap on a nanosecond time scale. This results in the sharp risetime for the onset of ionization. Ions produced in the ionization region, a few μm from the electron emitting spot are accelerated back. This bombardment with ∼ 100 eV ions leads to surface heating of the spot. Since the ion energy is deposited only within a few atomic layers at a time, the onset of breakdown by this mechanism requires much less current than the joule heating mechanism. Ion surface heating is initially orders of magnitude larger than joule heating. As more ions are produced, a positive space charge layer forms which enhances the electric field and thus strongly enhances the field emitted electron current. The localized build-up of plasma above the electron emitting spot then naturally leads to pressure and electric field distributions which ignite unipolar arcs. The high current density of the unipolar arc and the associated surface heating by ions provide the open-quotes explosiveclose quotes formation of a cathode spot plasma

  19. open-quotes Interaction-freeclose quotes measurements of quantum objects?

    White, A.G.; Kwiat, P.G.; James, D.F.

    1999-01-01

    It is now well established that the presence of an opaque classical object can be unambiguously determined by an open-quotes interaction-freeclose quotes measurement (IFM), where the object and the probe never directly interact. For quantum objects, we examine open-quotes interaction-freeclose quotes measurement (the object wavefunction is unchanged) and open-quotes interaction-freeclose quotes preparation (the object wavefunction is changed without physical interaction) and find that in general, neither is possible. We propose using high efficiency IFM close-quote s as a quantum information bus to connect disjoint quantum systems. copyright 1999 American Institute of Physics

  20. The evolution of magnetic structures due to open-quote open-quote magnetosonic streaming close-quote close-quote

    International Nuclear Information System (INIS)

    Ryutova, M.P.; Kaisig, M.; Tajima, T.

    1996-01-01

    The Faraday effect in gasdynamics called acoustic streaming and its accompanying nonlinear phenomena have analogies in plasma magnetohydrodynamics. A natural place where these effects may occur is the solar atmosphere with its strongly inhomogeneous magnetic fields concentrated in random magnetic flux tubes. Unlike acoustic streaming in the usual gasdynamics, nonlinear phenomena consisting in the generation of plasma flows by an oscillating magnetic flux tube, open-quote open-quote magnetosonic streaming close-quote close-quote (Ryutova 1986), is accompanied by a current drive and results in a specific evolution of magnetic structures: depending on the physical parameters of the medium a single magnetic flux tube may be either split into thinner flux tubes or dissolved diffusively into the ambient plasma. The effect of the open-quote open-quote magnetosonic streaming,close-quote close-quote on one hand, is an obvious candidate for the generation of mass flows at magnetic flux tubes sites, and on the other hand, it plays an essential role in the evolution of magnetic structures and ultimately may determine their lifetime. The theory of magnetosonic streaming is general and can be applied to other astrophysical objects that maintain oscillatory motions and contain structured magnetic fields or magnetic domains. We review analytical results and describe the origin of the magnetosonic streaming in magnetic flux tubes due to their interaction with acoustic waves. We study numerically the regime of the open-quote open-quote magnetosonic streaming close-quote close-quote corresponding to splitting of a magnetic flux tube. Our computer simulation supports and extends the analytical result. copyright 1996 The American Astronomical Society

    The {open_quotes}O{close_quotes} ring seal has been proposed to replace the van stone flange and the bellows thermal expansion assembly currently used on the existing Hanford piles to achieve water and gas seals, respectively. Possible advantages of the {open_quotes}O{close_quotes} ring seal are: (1) simplification of component parts and elimination of van stone corrosion; (2) simplification of maintenance; (3) lower costs of initial erection; (4) increased strength. This test supplements Test Project No. 27 (a preliminary thermal cycling test) in applying the {open_quotes}O{close_quotes} ring seal assembly to actual pile operating conditions.

  2. Can light Nambu-Goldstone boson loops counter the open-quote open-quote S argument close-quote close-quote against technicolor?

    International Nuclear Information System (INIS)

    Fleming, S.; Maksymyk, I.

    1996-01-01

    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 S measured at the Z pole, this effect is not sufficiently large to unambiguously counter the open-quote open-quote S argument close-quote close-quote against one-family technicolor. This result cannot be guessed a priori, but must be explicitly calculated. Our analysis entails an extended version of the STU oblique parametrization of Peskin and Takeuchi. In principle, this extended formalism (STUVWX) must be used when there are light new particles in loops. copyright 1996 The American Physical Society

  3. From hyperons to applied optics: open-quotes Winston Conesclose quotes during and after ZGS era

    International Nuclear Information System (INIS)

    Swallow, E.C.

    1994-01-01

    This paper discusses developments in light collection which had their origin in efforts to construct high performance gas Cerenkov detectors for precision studies of hyperon beta decays at the ZGS. The resulting devices, know generally as open-quotes compound parabolic concentrators,close quotes have found applications ranging from nuclear and particle physics experiments to solar energy concentration, instrument illumination, and understanding the optics of visual receptors. Interest in these devices and the ideas underlying them stimulated the development of a substantial new subfield of physics: nonimaging optics. This progression provides an excellent example of some ways in which unanticipated - and often unanticipatable - applied science and open-quotes practicalclose quotes devices naturally emerge from first-rate basic science. The characteristics of this process suggest that the term open-quotes spinoffclose quotes commonly used to denote it is misleading and in need of replacement

    Halsey, W.G.

    1994-01-01

    The topic of thermal loading of a potential repository at Yucca Mountain in Nevada has been the subject of intense discussion within the project technical community. While terms such as open-quotes Hot Repositoryclose quotes and open-quotes Cold Repositoryclose quotes are frequently used, they have not been clearly defined. In particular, the definition of a cold repository has remained the opinion of each individual. This has led to confusion and misunderstanding. In this paper, a number of observed definitions for a cold repository are discussed along with the technical implications, assumptions and inconsistencies. Finally, a common language is suggested

    International Nuclear Information System (INIS)

    Annon, M.C.

    1996-01-01

    The differentiation among open-quotes rightsizing,close quotes open-quotes downsizing,close quotes and open-quotes reengineeringclose quotes has been lost by many organizations. Also, unfortunately of late, the approaches to improved competitiveness and worker productivity are being viewed, by many companies, as neither worth the effort nor achieving the desired results. In some cases, the effort may actually create more negative results. This type of negative perception has been documented in a variety of sources that include the following: (1) less than half the companies reporting improvements in operating profits after the cuts were made, (2) the processes resulting in significantly degraded morale among more than 75% of the employees, (3) less than one-third of organizations reporting improvements in worker productivity, and (4) even Michael Hammer (the reengineering open-quotes guruclose quotes) believing that more than 50% and maybe as much as 70% of the organizations do not achieve the intended results. This paper describes an integrated organizational review process that was applied within a nuclear utility that did achieve the desired results

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

    Energy Technology Data Exchange (ETDEWEB)

    Pisarski, R.D. [Brookhaven National Lab., Upton, NY (United States)

    1997-09-22

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

    1994-01-01

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

    1995-01-01

    We define the open-quotes metaclose quotes-rigid motions as particular classes of time-like congruences which are solutions of intrinsically defined partial differential equations that generalize Born's conditions. We consider in particular two hierarchies of such congruences. The first one is a geometrically motivated direct generalization of the symmetry concept inherent in Born congruences. The second one is an indirect generalization based on the conditions which guarantee the existence of a particular class of adapted coordinates of space, named quo-harmonic coordinates, whose definition is akin to the definition of harmonic coordinates but which differs from it in an essential point

  11. A open-quotes Newclose quotes regime for nuclear weapons and materials

    International Nuclear Information System (INIS)

    Sutcliffe, W.G.

    1994-01-01

    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 newclose 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

  12. Compensation of the open-quotes Pacmanclose quotes tune spread by tailoring the beam current

    International Nuclear Information System (INIS)

    Furman, M.A.

    1995-04-01

    ' Factory'-like e + -e - colliders presently under design or construction achieve high luminosity by resorting to large numbers of closely-spaced bunches. The short bunch spacing implies that there are unavoidable parasitic collisions (PCs) in the neighborhood of the interaction point (IP). Since the bunch population of the beam is not uniform due to an intentional ion-clearing gap, the bunches at the head or tail of the train (open-quotes pacman bunchesclose quotes) experience different beam-beam tune shifts than those away from the edges (open-quotes typical bunchesclose quotes). The author presents here a method to minimize the vertical tune spread at the expense of increasing the horizontal tune spread (it is assumed that there is only one IP). Since the beam-beam dynamics for flat beams typically tolerates a significantly higher horizontal tune spread than a vertical tune spread, this method implies a net advantage. The author presents this discussion in the context of the PEP-II collider

    A fast, warm liquid calorimeter module with lead absorber immersed in tetramethyl pentane (TMP) as the liquid medium (i.e. a open-quotes swimming poolclose quotes configuration) has been built and tested in a high energy beam at FNAL, and exposed to intense radiation from a strong Co 60 source. A two-tower prototype, incorporating the concept of the electrostatic transformer for fast readout, exhibited very good uniformity and small cross-talk in the beam test. This same calorimeter was exposed to over 10 Mrad of radiation from the Co 60 source, and the electron drift lifetime was measured as a function of accumulated dose. The lifetime improved significantly with small doses of radiation, up to a few hundred krad, then decreased gradually at higher doses, and extrapolated to a minimum useful lifetime of 0.1 μs at over 150 Mrad. This result was confirmed by measurements on a small single-electrode test cell which was irradiated to more than 25 Mrad. In this case, the lifetime decreased from 10μs to 0.1 μs when extrapolated to a dose of over 600 Mrad. This cell was also used to measure the effect of positive ion open-quotes space chargeclose quotes buildup under intense radiation. The results suggest that such effects are small even at the highest intensity available, about 1.3 Mrad/day, for applied fields ≥25 kV/cm

    Study of decay characteristics of short-lived nuclides has fascinated nuclear chemists ever since the discovery of radioactivity. In the last two decades nuclides with half-lives in the range of several seconds to several tens of seconds have been explored. In addition to manual procedures, several automatic batch (autobatch) as well as continuous separation procedures have been developed for the study of these nuclides. The first part of the radiochemical techniques monograph entitled open-quotes Ultrafast Chemical Separationsclose quotes reviews the techniques used in fast separations. A collection of known fast procedures, arranged according to the name of the element, is presented in the second part. A total of 316 procedures for 75 elements are included

A single peak corresponding to this phase was found at momentum transfer q=2.86{Angstrom}{sup {minus}1} along six equivalent [11{bar 2}] directions of the noble metal substrate. Magnetic hysteresis of the field cooled Fe/Mn bilayers exhibited a characteristic shift along the field axis, indicating antiferromagnetic order in the expanded Mn with T{sub N}{ge}20K. The magnetic and structural data are consistent with understanding the expanded phase as trigonally distorted {alpha}-Mn. {copyright} {ital 1998 American Institute of Physics.}

    The degradation of radioiodine removal performance for impregnated activated carbons because of ageing is well established. However, the causes for this degradation remain unclear. One theory is that this reduction in performance from the ageing process results from an oxidation of the surface of the carbon. Radioiodine removing activated carbons that failed radioiodine removal tests showed an oxidized surface that had become hydrophilic compared with new carbons. We attempted to restore the performance of these {open_quotes}failed{close_quotes} carbons with a combination of thermal and chemical treatment. The results of these investigations are presented and discussed with the view of extending the life of radioiodine removing activated carbons. 4 refs., 2 tabs.

    Green close-quote s functions are valuable analytical tools for solving a myriad of boundary-value problems in mathematical physics. Here, Green close-quote s functions of the Laplacian and biharmonic operators are derived for a three-dimensional toroidal domain. In some sense, the former result may be regarded as open-quotes standard,close quotes but the latter is most certainly not. It is shown that both functions can be constructed to have zero value on a specified toroidal surface with a circular cross section. Additionally, the Green close-quote s function of the biharmonic operator may be chosen to have the property that its normal derivative also vanishes there. A open-quotes torsionalclose quotes Green close-quote s function is derived for each operator which is useful in solving some boundary-value problems involving axisymmetric vector equations. Using this approach, the magnetic vector potential of a wire loop is computed as a simple example. copyright 1997 American Institute of Physics

    At the 22nd Conference in Denver, we reported that the U.S. Army Surgeon General (SGJ) had approved our developmental material {open_quotes}Emery 3004{close_quotes} as a safe replacement for the suspected carcinogen DOP (dioctyl phthalate) in mask and filter testing throughout the Army. Subsequently the SG approved a second, less viscous material, {open_quotes}Emery 3002,{close_quotes} for similar applications. We have measured the viscosities and surface tensions of these liquids over a wide range of temperatures, and have initiated liquid breakup studies through Laskin and two-fluid nozzles. New measurements have been carried out with both liquids, e.g. using the ATI, Inc., TDA-4A cold generator to disperse aerosols for which droplet size distributions were measured using the TSI, Inc., Differential Mobility Particle Sizer (DMPS). Among the findings were that Emery 3004 performs much like DOP in the TDA-4A, with some possible advantages, while Emery 3002 in the TDA-4A produces mean droplet diameters about one-half those of Emery 3004 or DOP. This suggests that Emery 3002 could yield more rigorous filter tests with a smaller consumption of material. New laboratory results will be summarized. Sources of the {open_quotes}Emery{close_quotes} materials will be discussed since the production facility formerly operated by Emery is now run by the Ethyl Corporation and the source products are now known as {open_quotes}Ethylflo 192{close_quotes} (Emery 3002) and{open_quotes}Ethylflo 194{close_quotes} (Emery 3004).

    In June of 1992 the Waste Minimization Program at Rocky Flats Plant (RFP) began a study to determine the best methods of managing water-based industrial metalworking fluids in the plant`s Tool Manufacturing Shop. The shop was faced with the challenge of managing fluids that could no longer be disposed of in the traditional manner, through the plant`s liquid process waste drains, due to a problem they, were having causing in the Liquid Waste Operations Evaporator. The study`s goal was to reduce the waste coolants being generated and to reduce worker exposure to a serious health risk. Results of this study and those of a subsequent study to determine relative compatibilities of various coolants and metals, led to the application of a {open_quotes}zero waste{close_quotes} machine coolant management program. This program is currently saving the generation of 10,000 gallons of liquid waste annually, has eliminated worker exposure to harmful bacteria and biocides, and should result in extended machine tool life, increased product quality, fewer rejected parts, and decreases labor costs.

    It is shown that the extension of the standard model of electroweak interaction and QCD, which includes spontaneously broken horizontal local gauge symmetry, provides a quantitatively definite phenomenological description for almost all phenomena in particle physics and modern cosmology. In this model, the predictions of the standard model are combined with a description of the mass spectrum and mixing of quarks and leptons, and with the predictions of the neutrino mass spectrum and parameters of an invisible axion. This model also gives a quantitatively definite physical basis for the theory of inflation, baryosynthesis, and dark matter of the Universe. A complex analysis of physical, cosmological, and astrophysical predictions of the model singles out a narrow range of allowed values of parameters corresponding to the open-quotes effectiveclose quotes mixed cold-hot version of the theory describing the formation of the structure of the Universe.

    A new fish screen design-the modular inclined screen-promises to offer a versatile and cost-effective solution for fish protection in many situation. In an effort to provide the hydroelectric industry with more cost-effective alternatives to existing fish screen designs, the Electric Power Research Institute (EPRI) recently has undertaken several research projects. One focus of EPRI's research has been on the development and testing of high-velocity fish screens. This program has led to the development of a new screening concept, which shows promise for providing effective protection for a wide range of fish species at hydro plants, steam generating facilities, and irrigation diversions. The concept, known as the Modular Inclined Screen (MIS), currently is being evaluated in laboratory studies prior to field application. The screen is of open-quotes modularclose quotes design so as to provide the flexibility necessary for application at a broad range of water intakes. The module is suitable for installation in penstocks, canals, and head pond intakes. The MIS module consists of an entrance with a trashrack, dewatering stoplog slots, an inclined wedgewire screen set at a shallow angle of 10 to 20 degrees to the flow, and a bypass for diverting fish to a transport pipe. The screen is mounted on a pivot shaft so that it can be cleaned via rotation and backflushing. The module is completely enclosed, and is designed to operate at water velocities ranging from 2 to 10 feet per second depending on the fish species and life stages to be protected. Laboratory studies are under way to evaluate the design configuration that yields the best hydraulic conditions for safe fish passage, and the biological effectiveness of this design in diverting selected fish species to the bypass

    The first complete translations into English are presented of two articles written by the outstanding French scientist Henri Poincare and submitted by him in 1905 under the common title of open-quotes Sur la dynamique de l'electronclose quotes to different journals. In the present edition of these articles by H. Poincare, modern notation is used, and the articles are accompanied by comments written by A.A. Logunov. The author of the comments explains the profound physical meaning and essential novelty of the particular points and relationships established by Poincare. Such explanations are often interspersed with quotations from earlier articles by Poincare, thus clearly indicating that the main initial points of the new theory were put forward by the French scientist much before 1905, while certain concepts like 'local' time and the arbitrariness of simultaneity were given a clear explanation from the point of view of physical meaning. A.A. Logunov's book, presenting the works of Poincare on the development of relativity theory, has had quite a high success among specialists interested in the history of physics, and since 1984 it has been published in Russian three times. The present English-language edition is identical to the last 1988 Russian edition, and is dedicated to the 90th anniversary of Poincare's articles 'On the Dynamics of the Electron'. In preparing the English text, fragments were used of the translation of the long article by H.Poincare published in the book by Professor C.W. Kilmister from King's College in London/Special Theory of Relativity, Pergamon Press, New York, 1970/

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

  13. Crossed and Locked Quotes in a Multi-Market Simulation.

    2016-01-01

    Financial markets are often fragmented, introducing the possibility that quotes in identical securities may become crossed or locked. There are a number of theoretical explanations for the existence of crossed and locked quotes, including competition, simultaneous actions, inattentiveness, fee structure and market access. In this paper, we perform a simulation experiment designed to examine the effect of simple order routing procedures on the properties of a fragmented market consisting of a single security trading in two independent limit order books. The quotes in the two markets are connected solely by the routing decision of the market participants. We report on the health of the consolidated market as measured by the duration of crossed and locked states, as well as the spread and the volatility of transaction prices in the consolidated market. We aim to quantify exactly how the prevalence of order routing among a population of market participants affects properties of the consolidated market. Our model contributes to the zero-intelligence literature by treating order routing as an experimental variable. Additionally, we introduce a parsimonious heuristic for limit order routing, allowing us to study the effects of both market order routing and limit order routing. Our model refines intuition for the sometimes subtle relationships between the prevalence of order routing and various market measures. Our model also provides a benchmark for more complex agent-based models.

    Current technology is beginning to allow us to manipulate rather than just observe individual quantum phenomena. This opens up the possibility of exploiting quantum effects to perform computations beyond the scope of any classical computer. Recently Peter Shor discovered an efficient algorithm for factoring whole numbers, which uses characteristically quantum effects. The algorithm illustrates the potential power of quantum computation, as there is no known efficient classical method for solving this problem. The authors give an exposition of Shor close-quote s algorithm together with an introduction to quantum computation and complexity theory.

    Full Text Available The study examined the relationship of capital structure to profitability of quoted firms in Nigeria. The study was based on a panel data set from 1996 to 2010 comprising sixty non – financial companies. The study specified two panel regression models. Two profitability measures: Net Profit Margin (NPM and Operating Profit Margin (OPM were taken as the dependent variables respectively. The principal explanatory variable for each of the models was Debt Ratio (DR. The results of the study indicated that there was a significant negative relationship between capital structure and profitability of quoted companies in Nigeria. Indeed, the results the Pecking order theory that profitable firms do not target an optimal level of leverage to balance the benefits and costs of debt financing. Rather, firms use retained earnings first, then debts and finally equity. Such firms would actually be paying high tax charges and also high operating costs arising from over dependence on the money market for their funds requirements. It was recommended that appropriate fiscal policies, relevant capital market institutional and legal framework should be put in place. These measures, we believe, will ensure better access to funds and reduce the cost of doing business.

  1. The open-quotes synergisticclose quotes action of mixed irradiation with high-LET and low-LET radiation

    International Nuclear Information System (INIS)

    Suzuki, Shozo

    1994-01-01

    The combined modalities of various agents such as radiation, chemicals and physical agents are often used, and exposure to mixture of agents sometimes occurs in nature. However, it is not clear whether these combined effects are synergistic, partly because definition of the term open-quotes synergismclose quotes is confusing, as pointed out by Streffer and Mueller. It is, of course, desirable that the definition should be simple and widely applicable to all agents. Yet the underlying mechanisms of the effects of different agents are probably different, and the mechanisms of combined effects are different and more complicated than those of a single agent. It is therefore important to define synergism taking each underlying mechanism into consideration. From this viewpoint, the definitions of synergism which have been used to date are examined with respect to the effect of a mixture of different types of radiation on cells, and they are shown to be inappropriate and misleading. This is probably attributable to simply treating the resulting phenomena (cell survival in most cases) without adequately taking into consideration the knowledge of underlying biological mechanisms in defining the synergism that may occur with irradiation. This commentary discusses the inappropriateness of current definitions and proposes a new definition in terms of biological mechanisms as a counterproposal. 16 refs., 6 figs

  2. Investigating the construction of open-quotes pyramidclose quotes super-structures to dispose of radioactive and hazardous waste

    The technical challenges involved in disposing of radioactive and hazardous waste using systems that rely on open-quotes natural barriersclose quotes have been underestimated. Technology has advanced dramatically in the areas of materials, science, and engineering. As a result, traditional approaches to waste disposal must be rethought, focusing instead on ways to apply new technology breakthroughs to waste disposal problems. This paper will discuss problems currently faced by waste disposal systems that rely on natural barriers for containment, propose a general design and approach for constructing pyramid super-structures to dispose of (and store) waste, and present the benefits of such a system. The originality of this paper is that it proposes the construction of fully retrievable waste disposal systems that capitalize on the unique geometric properties of a pyramid and rely on engineered barriers and preventive measurements for containment, rather than natural barriers. In addition, this paper offers a new perspective on waste disposal issues confronting many countries. The desired effect is that by challenging conventional thought, new ideas could be developed to help solve existing problems. This paper is of specific interest to: (1) Policy makers, decisionmakers, and managers because the paper discusses the root causes of problems facing waste disposal and possible solutions. (2) Regulators because the paper discusses reasons for relying more on engineered barriers and preventive measurements to achieve confidence and reliability in containment. (3) Design engineers the paper offers new concepts for engineered barriers. 21 refs., 2 figs., 2 tabs

    In many experiments involving fast neutrons generated in nuclear reactions initiated by accelerator produced charged particle beams, it is important to be able to determine accurately the neutron yield from the target. A detector suitable for such applications should have: a constant efficiency over a large energy range; a fast time response; and the ability to discriminate between gamma rays and neutrons. The authors have constructed a open-quotes black neutron detectorclose quotes based on the design of Poenitz that has these characteristics. At the Lowell Van de Graaff accelerator laboratory neutrons are produced via the 7 Li(p,n) 7 Be reaction using a pulsed proton beam which impinges on metallic lithium targets. The pulsed beam enables the detector to be used in a time-of-flight spectrometer. Use of BC501 liquid scintillator permits neutron-gamma discrimination. The scintillator is viewed by five RCA 48796 photo tubes. The detector is housed in a massive shield of lead, polyethylene and lithium carbonate. The characteristics and use of this detector will be discussed

    The experimentally determined initial dissolution rate R 0 of nuclear glass was correlated with thermodynamic parameters and structural parameters. The initial corrosion rates of six open-quotes R7T7close quotes glass samples measured at 100 degrees C in a Soxhlet device were correlated with the glass free hydration energy and the glass formation enthalpy. These correlations were then tested with a group of 26 SON glasses selected for their wide diversity of compositions. The thermodynamic models provided a satisfactory approximation of the initial dissolution rate determined under Soxhlet conditions for SON glass samples that include up to 15 wt% of boron and some alumina. Conversely, these models are inaccurate if the boron concentration exceeds 15 wt% and the glass contains no alumina. Possible correlations between R 0 and structural parameters, such as the boron coordination number and the number of nonbridging oxygen atoms, were also investigated. The authors show that R 0 varies inversely with the number of 4-coordinate boron atoms; conversely, the results do not substantiate published reports of a correlation between R 0 and the number of nonbridging oxygen atoms

    Quote is sentences made in the hope that someone can become strong personalities, individuals who always improve themselves to move forward and achieve success. Social media is a place for people to express his heart to the world that sometimes the expression of the heart is quotes. Here, the purpose of this study was to classify Indonesian quote on Twitter using Naïve Bayes. This experiment uses text classification from Twitter data written by Twitter users which are quote then classification again grouped into 6 categories (Love, Life, Motivation, Education, Religion, Others). The language used is Indonesian. The method used is Naive Bayes. The results of this experiment are a web application collection of Indonesian quote that have been classified. This classification gives the user ease in finding quote based on class or keyword. For example, when a user wants to find a 'motivation' quote, this classification would be very useful.

    Before investing in a system, a prospective PV customer must not only have initial concept 'buy in,' but also be able to evaluate the tradeoffs associated with different system parameters. Prospective customers might need to evaluate disparate costs for each system attribute by comparing multiple bids. The difficulty of making such an evaluation with limited information can create a cognitive barrier to proceeding with the investment. This analysis leverages recently available data from EnergySage, an online solar marketplace, to offer the first data-driven characterization of quote variation faced by prospective PV customers, lending early insight into the decisions customers face once they have initial buy-in.

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

    Ever since the publication of the NRC Information Notice No. 87-32: Deficiencies in the Testing of Nuclear-Grade Activated Charcoal, nuclear power facilities in the US have struggled in their efforts to open-quotes...review the information for applicability to their facilities and consider action, if appropriate ...close quotes as stated in the notice. The encouragement of resident NRC inspectors at some nuclear power facilities has prompted a variety of responses ranging from no change at all in testing requirements to contemplated changes in plant technical specifications. This confusion is the result of a couple factors. The first factor is the lack of a current revision to NRC Regulatory Guide 1.52, the basic document used in nuclear power plant technical specifications for the testing of engineered-safety feature (ESF) post accident air cleaning systems. The second factor is the standards that have been written since the last revision of Reg. Guide 1.52 which include two revision of ANSI N509 and N510, two revisions of RDT M16-1T, two version of ASTM D3803, two versions of ASTM D4069, and three versions of an SME code AG-1. Few of the standards and codes listed above are commensurate with each other and, thus, present a nearly insolvable maze to the HVAC engineer asked to upgrade adsorbent testing requirements following the standards. This paper describes the authors experience with a number of nuclear power facilities in their efforts to meet the requirements of the new standards of testing adsorbents from nuclear power plant air cleaning systems. The existing standards are discussed in light of the current state of the art for adsorbent testing of adsorbent media from nuclear air treatment systems. Test results are presented showing the impact of new test requirements on acceptance criteria when compared to the old test requirements and recommendations are offered for solution of this testing problem in the future. 12 refs., 5 tabs

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

    In conventional Green close-quote s function methods the vertex function Γ is generally energy dependent. However, a model-space Green close-quote s function method where the vertex function is manifestly energy independent can be formulated using energy-independent effective interaction theories based on folded diagrams and/or similarity transformations. This is discussed in general and then illustrated for a 1p1h model-space Green close-quote s function applied to a solvable Lipkin many-fermion model. The poles of the conventional Green close-quote s function are obtained by solving a self-consistent Dyson equation and model space calculations may lead to unphysical poles. For the energy-independent model-space Green close-quote s function only the physical poles of the model problem are reproduced and are in satisfactory agreement with the exact excitation energies. copyright 1996 The American Physical Society

    Lifetimes of states in four of the M1-bands in {sup 198,199}Pb have been determined through a Doppler Shift Attenuation Method measurement performed using the Gammasphere array. The deduced B(M1) values, which are a sensitive probe of the underlying mechanism for generating these sequences, show remarkable agreement with Tilted Axis Cranking (TAC) calculations. Evidence is also presented for the possible termination of the bands. The results represent clear evidence for a new concept in nuclear excitations: {open_quote}magnetic rotation{close_quote}.

    The authors are the Executive Director and the Chief Financial Officer of the Ohio Petroleum Underground Storage Tank Release Compensation Board. Under the guidance of a public-sector governing board, they are responsible for implementing Ohio's UST Financial Assurance Fund program and for managing the resources and priorities necessary to maintain a solvent, practical approach to legislatively-mandated UST corrective action costs in Ohio. The paper will discuss: (1) the challenges of legislating and implementing a state assurance fund; (2) the task of defining the program's mission and coming to terms with open-quotes great expectationsclose quotes of tank owners and clean-up contractors; (3) implementing true cost-controls; how the regulatory back-drop contributes to costs and success; (4) managing the financial assets of an assurance fund and estimating future clean-up needs; (5) the search for the proper mix of financing alternatives, including reinsurance; (6) defining long-term success. The paper will develop the evolution of the essential elements of the Ohio Financial Assurance Fund and focus on the financial management of necessary resources to fulfill the public-sector mission. Managing claim costs and meeting the grassroots expectation of claimants underscore critical development issues: (1) establishing and communicating the Fund's purpose and management philosophy; (2) forging a companion relationship between industry and regulator; (3) how do such funds maintain solvency and dispel the notion that they constitute a open-quotes pot of goldclose quotes for environmental liability?

    Buildings E5485, E5487, and E5489, referred to informally as the open-quotes Ghost Townclose quotes complex, are potentially contaminated sites in the Edgewood section of Aberdeen Proving Ground. Noninvasive geophysical surveys, including magnetics, EM-31, EM-61, and ground-penetrating radar, were conducted to assist a sampling and monitoring program prior to decommissioning and dismantling of the buildings. The buildings are located on a marginal wetland bordering the west branch of Canal Creek. The dominant geophysical signature in the open-quotes Ghost Town close quotes complex is a pattern of northeast-southwest and northwest-southeast anomalies that appear to be associated with a trench/pipe/sewer system, documented by the presence of a manhole. Combinations of anomalies suggest that line sources include nonmetallic and ferromagnetic materials in trenches. On the basis of anomaly associations, the sewer lines probably rest in a trench, back-filled with conductive, amphibolitic, crushed rock. Where the sewer lines connect manholes or junctions with other lines, ferromagnetic materials are present. Isolated, unidentified magnetic anomalies litter the area around Building E5487, particularly to the north. Three small magnetic sources are located east of Building E5487

    At the beginning of the seventies, the concept of building small atomic power stations with direct conversion of the thermal energy of a reactor for supplying electricity and heat to consumers located at remote and inaccessible regions was developed on the basis of assessment calculations and technical studies made in the I.V. Kurchatov Institute of Atomic Energy. When new technical solutions were adopted to put this concept into practice, combined trials on a test stand were required. For this purpose, the nuclear thermoelectric test-demonstration assembly open-quotes Gammaclose quotes was built and put into operation in 1981. It is based on the three principles which determine the development of unattended self-regulating nuclear thermoelectric stations: using a water-water reactor with self-regulation of the power as a source of heat; using a cooling system without pumps but with natural circulation of the coolant in the primary and intermediate circuits for removing the hend thermoelectric conversion of heat into electricity. During the ten years of operation of the open-quotes Gammaclose quotes assembly, a research program on the principles of unattended self-regulating nuclear thermoelectric stations was carried out and the results are summarized

    We use residential solar photovoltaic (PV) quote data to study the role of firm size in PV installer pricing. We find that large installers (those that installed more than 1,000 PV systems in any year from 2013 to 2015) quote higher prices for customer-owned systems, on average, than do other installers. The results suggest that low prices are not the primary value proposition of large installers.

    Fermilab has initiated construction of a new Main Injector (150 GeV proton synchrotron) to take the place of the current Main RIng accelerator. open-quotes New Cultureclose quotes environmental and safety questions have been addressed. The paper will detail the necessary steps that were accomplished in order to obtain the permits which controlled the start of construction. Obviously these depend on site-specific circumstances, however, some steps are universally applicable. In the example, floodplains and wetlands were affected and therefore the National Environmental Protection Act (NEPA) compliance was a significant issue. The important feature was to reduce the relevant regulations to a concise set of easily understandable requirements and to perform the work required in order to proceed with the accelerator construction in a timely fashion. The effort required and the associated time line will be presented so that other new accelerator proposals can benefit from the experience gained from this example

    In an effort to minimize human error and maximize process control and test capabilities during Collider Dipole Magnets (CDM) production, General Dynamics is developing automated test and process control equipment; known as Test ampersand Process Control Modules (TPCM's). When used along with software designed to create open-quotes paperlessclose quotes process control documentation, the system becomes the Test ampersand Process Control System (TPCS). This system simplifies business decisions and eliminates some problems normally associated with process control documentation, while reducing human errors during CDM production.

    The vast majority of U.S. residential solar PV installers are small local-scale companies, however the industry is relatively concentrated in a few large national-scale installers. We develop a novel approach using solar PV quote data to study the price behavior of large solar PV installers in the United States. Through a paired differences approach, we find that large installer quotes are about higher, on average, than non-large installer quotes made to the same customer. The difference is statistically significant and robust after controlling for factors such as system size, equipment quality, and time effects. The results suggest that low prices are not the primary value proposition of large installer systems. We explore several hypotheses for this finding, including that large installers are able to exercise some market power and/or earn returns from reputations.

    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.

  10. Rotating black holes which saturate a Bogomol close-quote nyi bound

    1996-01-01

    We construct and study the electrically charged, rotating black hole solution in heterotic string theory compactified on a (10-D)-dimensional torus. This black hole is characterized by its mass, angular momentum, and a (36-2D)-dimensional electric charge vector. One of the features of this solution is that for D>5 its extremal limit saturates the Bogomol close-quote nyi bound. This is in contrast with the D=4 case where the rotating black hole solution develops a naked singularity before the Bogomol close-quote nyi bound is reached. The extremal black holes can be superposed, and by taking a periodic array in D>5, one obtains effectively four-dimensional solutions without naked singularities. copyright 1996 The American Physical Society

    Full Text Available I try to establish who is the philosopher or, if he is not found, the philosophical movement, who satisfies the doctrine about prayer and chance, that the Derveni papyrus’ author attributes to the «physicus» quoted in column IV, so that this philosopher can probably be identified with this physicus. In this context, I discuss the possibility, defended by Ferrari, of the physicus in question being Democritus, and I give complementary arguments in favor of this hypothesis.

  12. Non-negative Feynman endash Kac kernels in Schroedinger close-quote s interpolation problem

    International Nuclear Information System (INIS)

    Blanchard, P.; Garbaczewski, P.; Olkiewicz, R.

    1997-01-01

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

  13. Financial Leverage Behaviour and Firm Performance: Evidence from Publicly Quoted Companies in Nigeria

    Directory of Open Access Journals (Sweden)

    Godsday Okoro Edesiri

    2014-08-01

    Full Text Available This paper scrutinizes financial leverage behaviour and firm performance of publicly quoted companies in Nigeria. Data of Leverage, Profitability and Firm Size were sourced from the Nigerian Stock Exchange Fact-book and Annual Report and Accounts of 120 publicly quoted companies in Nigeria during the period 1990 through 2013. Findings suggest that profitability and firm size had a negative effect on financial leverage behaviour of publicly quoted companies in Nigeria. Thus, it was recommended that firms should carry out projects that would help enhance size and profitability in all aspect of the firm. Size in terms of assets would help increase the internal funding. This in turn will have a positive impact on the financial structure of firm as more of internally generated funds will be used instead of external borrowings. Firms should not assume that making of profit shows good application of leverage as this was not found to be true from the analysis. This implies that the result can be relied upon for policy direction.

    2016-12-01

    Full Text Available This study examined executive remuneration and firms’ performance in Nigeria. Specifically, the study seeks to ascertain the nexus between executive remuneration, firm size and board size variables and the performance of quoted companies. The population of the study consists of all the quoted firms as at 31st December, 2014. A sample of sixty (60 companies excluding non- financial firms was selected for the period 2013 and 2014. Summary statistics such as descriptive, correlation and granger causality tests were used. Inferential statistics, using panel Generalized Least Square (EGLS with fixed effect was used for the purpose of empirical validations. This was after the application of diagnostic test to enhance the study. The study ascertained that executive remuneration has a relationship with firm performance, but negatively impacted on it; though was not statistically significant. Firm size was ascertained not to have significant positive relationship with firms’ performance; though it has a causality relationship with the performance of the firms. Board size was found to negatively affect the performance of firms and is statistically not significant. Premised on this, the study suggests that executive remuneration of quote firms should be pegged constantly in a flexible manner. This will enable shareholders known the causality relationship between what is paid to the executive and how that influence performance.

    AEX quoted businesses in the Netherlands have shown an almost continuously increasing tendency towards sustainability in the period 2002-2006. Leaders are the chemical industry, the oil and gas sector, the financial sector and food companies. Little attention for sustainability is yet to be detected in business houses and publishing houses, although the topic is gaining interest. The assertion that sustainability translates into a higher market value of shares cannot be confirmed. A statistical correlation has been noticed, though, between sustainability attitude and environmental performance [mk] [nl

    Full Text Available Several studies, explaining the factors affecting stock returns, have been published both in developed and developing countries. In many of these papers, either cross-sectional or time series methods have been applied. In this study, Dynamic Panel Data Analysis Methods have been conducted to explain the factors affecting stock returns of 64 manufacturing firms that are continuously quoted in ISE during the period of 2003-2007. The results indicate that stock performance, financial structure, activity and profitability ratios can be used to explain the stock returns as well as the oil prices, economic growth, exchange rate, interest rate, and money supply.

    The goal of this article is to provide a practical method to calculate, in a scalar theory, accurate numerical values of the renormalized quantities which could be used to test any kind of approximate calculation. We use finite truncations of the Fourier transform of the recursion formula for Dyson close-quote s hierarchical model in the symmetric phase to perform high-precision calculations of the unsubtracted Green close-quote s functions at zero momentum in dimension 3, 4, and 5. We use the well-known correspondence between statistical mechanics and field theory in which the large cutoff limit is obtained by letting β reach a critical value β c (with up to 16 significant digits in our actual calculations). We show that the round-off errors on the magnetic susceptibility grow like (β c -β) -1 near criticality. We show that the systematic errors (finite truncations and volume) can be controlled with an exponential precision and reduced to a level lower than the numerical errors. We justify the use of the truncation for calculations of the high-temperature expansion. We calculate the dimensionless renormalized coupling constant corresponding to the 4-point function and show that when β→β c , this quantity tends to a fixed value which can be determined accurately when D=3 (hyperscaling holds), and goes to zero like [Ln(β c -β)] -1 when D=4. copyright 1998 The American Physical Society

    Full Text Available As important information conciliator, audit report is all the time a focus of audit firms, companies, regulators and investors and its report lag directly determines the usefulness of decision making. We examined the audit report lag of companies quoted in the Nigeria stock exchange for the period 2008 to 2011. The investigation was conducted on a pooled sample of 60 firms across industries (Construction, Breweries, Oil & Gas, Health care, Packaging, Insurance, Publishing, Food Products, Automobiles, Hotel & tourism, Real Estate, Mortgage, ICT, Agro-Allied, Building Materials, Conglomerates, Courier and Banking. The results show that age of a company and total asset has a significant impact on audit report lag in Nigeria. However, the result indicates that Firm size and firm switch has no significant relationship on audit report lag in Nigerian companies. We recommended that further research area on audit report lag should increase the sample size and also the number of years under investigation. Also, Policy makers should look into the audit report lag of quoted companies in Nigeria and formulate policies to enforce compliance. This will assist in boosting investors’ confidence and also guide them in taken timely quality decisions either to invest or de-invest.

    Full Text Available This study aimed at investigating the impact of value-added tax on corporate financial performance of quoted companies. To achieve this purpose, we developed some hypotheses and critically reviewed existing theoretical and empirical literatures. Agribusinesses quoted in the Nigerian Stock Exchange Factbook of 2009 were considered as the population for this study. The population elements include the General Managers, Chief Accountants, Finance Managers, Chief Internal Auditors, External Auditors, and Tax Administrators of the selected companies. A total of forty (42 respondents were considered for this study. A well structured questionnaire designed in five-point Likert Scale was administered on the respondents to elicit their responses. The data generated for this study were presented in tabular form and analyzed using frequencies and simple percentages while the stated hypotheses were statistically tested with the simple regression analysis and the t-test. Our findings indicated that Value-Added Tax (VAT impacted negatively on the financial performance of agribusinesses though the impact is of insignificant value. Based on our findings, we recommended that agribusinesses should endeavour to keep appropriate source documents of all transactions for efficient VAT operations and that the governments should ensure that proper tax incentive scheme is designed and fully implemented to promote the growth of agribusinesses, in Nigeria.

    2016-01-01

    Full Text Available The study examined the impact of market liquidity on investment decision of 50 non-financial quoted companies in Nigeria between 2006 and 2012. The study employed secondary source of data collection. Data collected were analyzed using descriptive statistics and inferential statistics such as pool OLS and fixed effect model. The results showed that Size of the Firm (FS and Firms’ Age (FAGE were the only significant determinants of Return on Investment (ROI. The turnover ratio (TOR which is a proxy for market liquidity had positive but insignificant effect on ROI. Based on the above findings, the study concluded that for most of the companies operating in the non-financial sector of the Nigerian economy, the influence of market liquidity on investment decision is positive, but not significant. The study recommended that management should place more emphasis on the firm age and in particular firm size as they can be employed to predict the return on investment.

    An analytical relationship between current density and applied electric field in reversed field pinch (RFP) plasmas has been derived in the framework of the kinetic dynamo theory, that is assuming a radial field-aligned momentum transport caused by the magnetic field stochasticity. This Ohm close-quote s law yields current density profiles with a poloidal current density at the edge which can sustain the magnetic field configuration against resistive diffusion. The dependence of the loop voltage on plasma current and other plasma parameters for RFP experiments has been obtained. The results of the theoretical work have been compared with experimental data from the RFX experiment, and a good agreement has been found. copyright 1997 The American Physical Society

    Full Text Available In his cognitive model called “mithological machine”, Furio Jesi proposes to circumscribe the concept of “myth” by means of a technique of critical composition of data and doctrines about the myth and the mythology. The model not only seeks to brave scientific-methodological reasons but also ethical-political ones. It’s about avoiding all the evocation and instrumentalization of myth in view of a political interest. This work analyzes the way as the model of Jesi resumes and develops two motives of Walter Benjamin’s work: (1 the one known as method of the quote without quotation marks and (2 the criticism of the reactionary theories of myth, specifically regarding the rehabilita­tion of Bachofen in the German culture from 1920’s and 1930’s.

  8. Resilience as resistance to the new managerialism: portraits that reframe nursing through quotes from the field.

    2016-01-01

    This paper acknowledges the relationship between resilience and the new managerialism of contemporary nursing. Qualitative portraiture methodology. The new managerialism in hospital settings results in a rapidly increasing turnover of acutely ill or comorbid patients, which directly relates to retention and quality service. In education settings, the management imperative to recruit more students into the profession combined with financial cutbacks leads to similar tensions. In aged care the trend equates care directly with funding, with the same effect. Yet despite this, many registered nurses remain working. Portraiture explored 'why' nurses remain in workplaces often described as awful. The resilience of nurses is seen through their stories and reframed to highlight resilience as a form of resistance to the new managerialism inherent in contemporary healthcare. This paper describes some of the hallmarks of new managerialism where workforce pressures force practices that do not value the 'human resource'. The quotes from the field give insight into the nurse's world view and have implications for managers, educators and employers, as well as for consumers of nursing care. © 2015 John Wiley & Sons Ltd.

    Full Text Available Pseudocysts constitute the most basic cystic lesions of the pancreas. Symptomatic cysts may be treated by means of both minimally invasive methods and surgery. Currently, it is believed that approximately 5% of cystic lesions in the pancreas may in fact, be neoplastic cystic tumors. Their presence is manifested by generally irregular multilocular structures, solid nodules inside the cyst or in the pancreatic duct, frequently vascularized, as well as fragmentary thickening of the cystic wall or septation. Aim: The aim of this paper was to present current management, both diagnostic and therapeutic, in patients with pancreatic pseudocysts and cystic tumors. The article has been written based on the material collected and prepared in the author’s Department as well as on the basis of current reports found in the quoted literature. Material and methods, results: In 2000–2012, the Second Department of General, Gastrointestinal and Oncological Surgery of the Alimentary Tract treated 179 patients with cystic lesions in the region of the pancreas. This group comprised 12 cases of cystic tumors and 167 pseudocysts. Twenty-three patients (13.8% were monitored only and 144 received procedural treatment. Out of the latter group, 75 patients underwent drainage procedures and 48 were qualified to endoscopic cystogastrostomy or cystoduodenostomy. The endoscopic procedure was unsuccessful in 11 cases (23%. In a group of patients with a pancreatic cystic tumor (12 patients, 6 of them (50% underwent therapeutic resection of the tumor with adequate fragment of the gland. Conclusions: Endoscopic drainage is an effective and safe method of minimally invasive treatment of pancreatic cysts. The patients who do not qualify to endoscopic procedures require surgical treatment. The differentiation of a neoplasm from a typical cyst is of fundamental significance for the selection of the treatment method.

The transformation results in the formation of second phases and in an increase of the intra grain critical current density at 1 T of five times. This increase is believed to express improved pinning properties of the superconducting crystals. The prepared pinning centres are believed to be e.g. coherent precipitates (Guinier-Preston-zones) within the superconducting crystals.

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

    Tannenbaum, M.J.

    1993-01-01

    Experience in analyzing the data from Light and Heavy Ion Collisions in terms of distributions rather than moments suggests that conventional fluctuations of multiplicity and transverse energy can be well described by Gamma or Negative Binomial Distributions (NBD). Multiplicity distributions were obtained for central 16 O+Cu collisions in bins of δη= 0.1,0.2, 0.3 .... 0.5,1.0, where the bin of 1.0 covers 1.2 < η < 2.2 in the laboratory. NBD fits were performed to these distributions with excellent results in all δη bins. The κ parameter of the NBD fit increases linearly with the δη interval, which is a totally unexpected and particularly striking result. Due to the well known property of the NBD under convolution, this result indicates that the multiplicity distributions in adjacent bins of pseudorapidity δη ∼ 0.1 are largely statistically independent.

    1996-01-01

    An extension of the fermionic particle-particle propagator is presented that possesses similar algebraic properties to the single-particle Green close-quote s function. In particular, this extended two-particle Green close-quote s function satisfies Dyson close-quote s equation and its self energy has the same analytic structure as the self energy of the single-particle Green close-quote s function. For the case of a system interacting with one-particle potentials only, the two-particle self energy takes on a particularly simple form, just like the common self energy does. The new two-particle self energy also serves as a well behaved optical potential for the elastic scattering of a two-particle projectile by a many-body target. Due to its analytic structure, the two-particle self energy avoids divergences that appear with effective potentials derived by other means. Copyright copyright 1996 Academic Press, Inc

    Melissa M Baese-Berk

    Full Text Available Neil Armstrong insisted that his quote upon landing on the moon was misheard, and that he had said one small step for a man, instead of one small step for man. What he said is unclear in part because function words like a can be reduced and spectrally indistinguishable from the preceding context. Therefore, their presence can be ambiguous, and they may disappear perceptually depending on the rate of surrounding speech. Two experiments are presented examining production and perception of reduced tokens of for and for a in spontaneous speech. Experiment 1 investigates the distributions of several acoustic features of for and for a. The results suggest that the distributions of for and for a overlap substantially, both in terms of temporal and spectral characteristics. Experiment 2 examines perception of these same tokens when the context speaking rate differs. The perceptibility of the function word a varies as a function of this context speaking rate. These results demonstrate that substantial ambiguity exists in the original quote from Armstrong, and that this ambiguity may be understood through context speaking rate.

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

    The electron drift velocities and corresponding mean energies have been calculated numerically using an approximate two-term solution of the Boltzmann transport equation for Ar/N 2 gas mixtures at electric field-to-gas density ratios (E/N) below 2.0x10 -20 Vm 2 (20 Td) and for He/Kr mixtures at E/N below 5.0x10 -21 Vm 2 (5.0 Td). The results are compared with predictions obtained from a method proposed by Chiflikian based on an open-quotes analog of Blanc close-quote s lawclose quotes [Phys. Plasmas 2, 3902 (1995)]. Large differences are found between the results derived from the Blanc close-quote s law method and those found here from solutions of the transport equation that indicate serious errors and limitations associated with use of the Blanc close-quote s law method to compute drift velocities in gas mixtures. copyright 1997 American Institute of Physics

    Full Text Available In the last ten years, the Internet and applications of it have been increasingly widely employed in modern business operations. In developed countries, the Internet is used with increasing frequency for financial reporting. And accordingly a large amount of academic research has been done into the area. Since no such research has yet been carried out in Croatia, it is a research area that is undoubtedly of interest. This investigation was carried out on a basic sample of 38 joint stock companies quoted on Croatian bourses, the shares of all of them being actively traded. The results showed that twenty of the companies made use of Internet financial reporting and eighteen had no such practice. Companies that use Internet financial reporting on the whole publish the annual reports together with the reports of their auditors. In addition, most of the companies use the PDF format for the reports that they publish. Empirical data show that the firms that use Internet financial reporting are on the whole larger and more profitable, and that their shares are more active on the bourses than the shares of companies that have no such reporting practice. Also established was a statistically significant propensity among financial institutions to use Internet reporting. Joint stock companies in the tourist sector were shown not to have a propensity for Internet financial reporting. Bearing in mind the expected growth of GDP, the growth of the capital market, with the constant growth in the number of Internet users, investment in financial reporting on the Internet could be a useful decision for joint stock companies that wish to enhance the transparency of their operations.

  6. {open_quotes}Lure{close_quotes} North Korea

    Energy Technology Data Exchange (ETDEWEB)

    Park, M.Y.M.

    1994-12-31

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

    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

    Superheated Drop Dosimeters (SDD) offer a sensitive, immediate measure of the neutron dose equivalent, but their dynamic range is limited and their response varies with temperature, pressure, and vibration. They contain thousands of superheated liquid drops in a stabilizing matrix. High linear energy transfer (LET) radiation triggers vaporization of the drops into visible bubbles. If the matrix is a liquid, the bubbles slowly rise, and the number present indicates the dose rate. Dose may be measured by displacement of the matrix, or by counting the sounds of vaporization. If the matrix is a gel, the bubbles are fixed, and their number is proportional to the dose equivalent. Our research has focused on modeling and elimination of the environmental response, extension of the dynamic range, and tests and evaluations of prototype devices

    Counselees' motives for seeking genetic counseling for hereditary cancer have already been investigated, however not using instruments based on counselees' perspective. In addition, expectations regarding the process of counseling have scarcely been assessed. This article describes the construction and psychometric properties of the QUOTE-gene(ca), a counselee-centered instrument intended to measure needs and preferences in genetic counseling for hereditary cancer. Formulation of the items involved input from counselees and the instrument was derived from a conceptual framework for measuring patient satisfaction. Two-hundred new counselees completed a questionnaire containing the instrument and measures of coping style (TMSI), generalized anxiety (STAI) and cancer-related stress reactions (IES), prior to their first consultation. Results showed that the instrument captures relevant issues of concern with high internal consistency, and was associated, as expected, with validated measures of coping style and distress. Responses showed that major concerns prior to counseling relate to: receiving information about risk and preventive strategies; the procedure of counseling; and preferences on how the interaction with the counselor proceeds. Receiving emotional support and discussing emotional aspects were considered relatively less important. Increasing insight into individual needs may help counselors in better addressing these concerns, potentially increasing the likelihood of successful counseling.

    1997-01-01

    We investigate de Haas endash van Alphen (dHvA) oscillations in the mixed state of a type-II two-dimensional superconductor within a self-consistent Gor close-quote kov perturbation scheme. Assuming that the order parameter forms a vortex lattice we can calculate the expansion coefficients exactly to any order. We have tested the results of the perturbation theory to fourth and eighth order against an exact numerical solution of the corresponding Bogoliubov endash de Gennes equations. The perturbation theory is found to describe well the onset of superconductivity close to the transition point H c2 . Contrary to earlier calculations by other authors we do not find that the perturbative scheme predicts any maximum of the dHvA oscillations below H c2 . Instead we obtain a substantial damping of the magnetic oscillations in the mixed state as compared to the normal state. We have examined the effect of an oscillatory chemical potential due to particle conservation and the effect of a finite Zeeman splitting. Furthermore, we have investigated the recently debated issue of the possibility of a sign change of the fundamental harmonic of the magnetic oscillations. Our theory is compared with experiment and we have found good agreement. copyright 1997 The American Physical Society

    Previous calculations by Geiger and Isgur showed that systematic cancellations among hadronic loops occur for u bar u↔s bar s mixing in all the low-lying nonets except 0 ++ . They suggested it is due to 3 P 0 dominance of the effective quark-antiquark (q bar q) pair creation operator. Here we give a general argument that there should be a large mixing for 0 ++ nonet from hadronic loops no matter what kind of model is assumed for q bar q creation. By the same argument we show that the Okubo-Zweig-Iizuka (OZI) rule should be best obeyed in the 1 -- , 2 ++ , and 3 -- nonets, but not very well obeyed in the 0 -+ , 1 +- , and 1 ++ nonets. All these model independent expectations are compatible with calculations by Geiger and Isgur using the 3 P 0 model as well as experimental data. A similar argument also suggests a large hadronic loop contribution for the p bar p→φφ reaction. copyright 1996 The American Physical Society

    Three important criteria are used to tune the undulator are: reduce longitudinal phase errors, have approximately equal two plane focusing and have a good overlap between the electron beam and the optical beam. Although these criteria are the main design goals it is hard to meet them directly from the assembling. Small errors inevitably appear during the assembly, even when care is taken to keep the tolerances as tight as possible. The magnetic field was constantly monitored during construction using the pulsed wire method. However some kind of tuning mechanism is always needed to improve the performance of the undulator. The undulator we designed and build is of the Hybrid type, i.e. permanent magnets and high permeable poles. The well known method of using small permanent magnets to correct the field errors is nearly impossible due to the presence of iron poles. Hence, as a logical step, we decided to try to correct the various errors with shims in the form of small iron plates. The shims were put on the pole face at the edge of the poles. Different configurations were used to correct the different kind of errors. In the presentation an overview of the various shim configurations will be discussed. Steering errors are quite easy to correct, since only dipole fields are involved. We did put quite some effort in correcting the quadrupole errors. Gradients dBy/dx and dBx/dy were easy to correct with two shims on one side. The other gradients, on the other hand needed extensive shimming to be corrected. The error correction is limited by the presence of sextupole errors. We even found by experience that sextupole errors increased with the number of shims used. The ratio of the focusing strength of the undulator is measured to be 3/2, being slightly stronger in the direction of the wiggle motion. Longitudinal phase errors are introduced by amplitude and wavelength deviations in the undulator.

    The Columbia Fuel Fabrication Facility of the Westinghouse Commercial Nuclear Fuel Division manufactures low-enriched uranium fuel and associated components for use in commercial pressurized water power reactors. To support development of a comprehensive integrated safety assessment (ISA) for the facility, as well as to address increasing U.S. Nuclear Regulatory Commission (NRC) expectations regarding such a facility's criticality safety assessments, a project is under way to complete criticality safety evaluations (CSEs) of all plant systems used in processing nuclear materials. Each CSE is made up of seven sections, prepared by a multidisciplinary team of process engineers, systems engineers, safety engineers, maintenance representatives, and operators. This paper provides a cursory outline of the type of information presented in a CSE

    1997-01-01

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

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

    The code package SVECHA for the modeling of in-vessel core degradation (CD) phenomena in severe accidents is being developed in the Nuclear Safety Institute, Russian Academy of Science (NSI RAS). The code package presents a detailed mechanistic description of the phenomenology of severe accidents in a reactor core. The modules of the package were developed and validated on separate effect test data. These modules were then successfully implemented in the ICARE2 code and validated against a wide range of integral tests. Validation results have shown good agreement with separate effect tests data and with the integral tests CORA-W1/W2, CORA-13, PHEBUS-B9+.

    1995-01-01

    The development of the theory of R-functions has stimulated the emergence of efficient numerical-analytical methods for a wide class of problems associated with physico-mechanical fields. R-functions are the basis for computer-aided level source language, which is sufficiently close to an ordinary mathematical language. Despite the powerful capabilities of the POLE family systems and the extensive support for the analysis of computation results, these systems are still not widely used in practice, as they assume a user with special mathematical qualifications. It is therefore necessary to develop special-purpose systems that do not require the user to be proficient in mathematical physics, the theory of R-functions, variational methods, etc. In other words, we need systems that are oriented toward technical-profile engineers specializing in design and calculations. In this article, we propose some principles for the construction of a special-purpose interactive programming system POLE-PLAST capable of solving problems in the mechanics of deformable solids of complex shape. As the specific application domain for the description of the system we have chosen problems that deal with bending, stability, and vibration of elements of thin-walled constructions modeled by thin plates

    1997-01-01

    Probabilistic Risk Assessment (PRA) has become an increasingly important tool in the nuclear power industry, both for the Nuclear Regulatory Commission (NRC) and the operating utilities. The NRC recently published a final policy statement, SECY-95-126, encouraging the use of PRA in regulatory activities. Human reliability analysis (HRA), while a critical element of PRA, has limitations in the analysis of human actions in PRAs that have long been recognized as a constraint when using PRA. In fact, better integration of HRA into the PRA process has long been a NRC issue. Of particular concern, has been the omission of errors of commission - those errors that are associated with inappropriate interventions by operators with operating systems. To address these concerns, the NRC identified the need to develop an improved HRA method, so that human reliability can be better represented and integrated into PRA modeling and quantification. The purpose of the Brookhaven National Laboratory (BNL) project, entitled 'Improved HRA Method Based on Operating Experience' is to develop a new method for HRA which is supported by the analysis of risk-significant operating experience. This approach will allow a more realistic assessment and representation of the human contribution to plant risk, and thereby increase the utility of PRA. The project's completed, ongoing, and future efforts fall into four phases: (1) Assessment phase (FY 92/93); (2) Analysis and Characterization phase (FY 93/94); (3) Development phase (FY 95/96); and (4) Implementation phase (FY 96/97 ongoing)

  9. The role of the open-quotes stress protein responseclose quotes in hormesis

    International Nuclear Information System (INIS)

    Smith-Sonneborn, J.

    1992-01-01

    Hormesis refers to the phenomenon of induction of beneficial effects by low doses of otherwise harmful physical or chemical agents: 'a little bit of bad can be good for you.' That the hormetic response may operate by a common mechanism has already been proposed, but this review is the first to propose the hypothesis that the common pathway is a heat shock-like response. The heat shock response is a model for a more general phenomenon, called the stress response. The stress response is characterized by increased synthesis of a family of stressor specific proteins with concomitant reduction of synthesis of most of the proteins transcribed prior to the exposure to the toxic agent. The stress response has been characterized using heat, radiation, heavy metals, and oxidizing agents as the stressors. This chapter includes: Identification of agents known to induce both the stress response and hormetic phenomena; A description of the unique and common pathways in the stress response to three stressors - heat, DNA-damaging agents, and teratogens; The stress response as a model for teratogen-induced damage; A theory explaining the paradoxical beneficial response to low doses of an otherwise harmful agent via a stress-response pathway

    The Columbia Fuel Fabrication Facility of the Westinghouse Commercial Nuclear Fuel Division manufactures low-enriched uranium fuel and associated components for use in commercial pressurized water power reactors. To support development of a comprehensive integrated safety assessment (ISA) for the facility, as well as to address increasing U.S. Nuclear Regulatory Commission (NRC) expectations regarding such a facility`s criticality safety assessments, a project is under way to complete criticality safety evaluations (CSEs) of all plant systems used in processing nuclear materials. Each CSE is made up of seven sections, prepared by a multidisciplinary team of process engineers, systems engineers, safety engineers, maintenance representatives, and operators. This paper provides a cursory outline of the type of information presented in a CSE.

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

    In the two-beam accelerator scheme of CLIC the Transfer Structure serves the purpose of extracting 30 GHz power from the drive beam. The purpose of the 3D simulations of the 30 GHz CTS using the MAFIA set of codes has been to assist the designers in the choice of the final dimensions by appreciating the sensitivity of the RF characteristics to the mechanical parameters. The results of the frequency domain analysis have allowed plotting of the dispersion curves of the waveguides and appreciation the relative importance of higher modes. The time domain investigations have produced results on the shape and magnitude of the beam-induced longitudinal and transverse wake fields and of the loss factors

    A long pulse spallation neutron source (LPSS) having about 20 times more time average thermal flux than its short pulse counterpart (SPSS) at the same proton beam power and featuring a pronounced time structure not available on CW sources (CWNS) of equal time average flux can in principle host instruments typical for both classes of facilities. While the need for additional choppers introduces some restrictions on inverted time of flight techniques typical for SPSS and high incident neutron energies are not easier to use on LPSS than on CWNS, taking advantage of the pulsed nature of the neutron flux can enhance significantly the performance of direct time of flight instruments and of crystal spectrometers or diffractometers. In the paper some of the options are reviewed in a general manner and criteria are discussed which can be used to optimize the performance enhancement

    Community relations is becoming an increasingly prominent aspect of the environmental restoration business. Historically the DOE has been closed to public scrutiny, dating back to the origins of the weapons complex in the Manhattan Project. Rocky Flats community relations can be viewed as having its painful start on June 6, 1989, when over fifty FBI agents entered Rocky Flats to gather information on alleged operational and procedural violations of environmental law. The Plutonium Recovery Modification Project (PRMP) was the first initiative to hold public meetings and provide for real dialogue in May 1990. Building on this start, the last year has seen a phenomenal growth of Rocky Flats community relations activities, now averaging over one public forum of some kind per week. We believe the effort has been very successful in building understanding and credibility within the local community. Although community relations is not a panacea, neither is it an ogre. Community relations for environmental restoration is mandated by law, and for good management is a necessary part of the DOE for the 1990's and beyond. Properly utilized, it can augment an ongoing environmental program and help smooth the road to success

    Full Text Available Corporate financing decision of firms has remained a debatable issue in both corporate and academic discussions. The present study aims to investigate the factors responsible for the financing decision of firms in Nigeria. To achieve this, 63 nonfinancial firms listed on the Nigerian stock exchange were selected based on data availability for the period of 2001 to 2010. Financial firms were excluded because of their similar regulatory framework and in order to ease the comparability of results. While most studies focused on debt-ratio as a measure of leverage, the present study uses the ratio of total debt and total assets. The empirical findings from the static panel regression analysis confirms that Nigerian firms tends toward internal financing through retained earnings, equity and other short term funds, against long term financing majorly through debts and other long term loans. One factor that could be said to account for this decision is the ill developed bond market in the country as well as the accessibility of firms to long term finances from the existing sources that is marred with high interest rates and huge collaterals.

    Interventional cardiologists may be immune to stress, allowing them to perform complex percutaneous interventions under pressure. To assess heart rate (HR) variations as a surrogate marker of stress of interventional cardiologists during percutaneous cardiac procedures and in every-day life. This is a single-centre observational study including a total of six male interventional cardiologists performing coronary interventions and pacemaker implantations. Participants were asked to record their HR with the Apple Watch Device during procedures, every-day life and control activities such as outpatient consultations, sport, marital conflicts and sexual intercourse. Average daily HR was 88±17 bpm. During work days, HR increased significantly during procedures (90±17 bpm) compared with days outside the cathlab (87±17 bpm, p=0.02). The average HR was higher during a regular week working (88±16 bpm) compared with weekends off (84±18 bpm, p=0.002). Complex cardiac procedures were associated with higher HR up to 122 bpm. Peak HR were higher during physical exertion. Of note, participants complained of hypersexuality and mania after night shifts. Work and especially percutaneous cardiac procedures increase HR independently of physical exertion suggesting that interventional cardiologists experience mental stress and emotions.

    The widespread availability of high-quality, high-frequency data has revolutionised the study of financial markets. By describing not only asset prices, but also market participants' actions and interactions, this wealth of information offers a new window into the inner workings of the financial ecosystem. In this original text, the authors discuss empirical facts of financial markets and introduce a wide range of models, from the micro-scale mechanics of individual order arrivals to the emergent, macro-scale issues of market stability. Throughout this journey, data is king. All discussions are firmly rooted in the empirical behaviour of real stocks, and all models are calibrated and evaluated using recent data from Nasdaq. By confronting theory with empirical facts, this book for practitioners, researchers and advanced students provides a fresh, new, and often surprising perspective on topics as diverse as optimal trading, price impact, the fragile nature of liquidity, and even the reasons why people trade a...

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

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

    1994-01-01

    Some seeming logical deficiencies in a recent paper are described. The author responds to the arguments of the work by de Muynck, De Baere, and Martens (MDM), who argue it is widely accepted today that some sort of nonlocal effect is needed to resolve the problems raised by the works of Einstein, Podolsky, and Rosen (EPR) and John Bell. In MBM a variety of arguments are set forth that aim to invalidate the existing purported proofs of nonlocality and to provide, moreover, a local solution to the problems uncovered by EPR and Bell. Much of the argumentation in MBM is based on the idea of introducing 'nonideal' measurements, which, according to MBM, allow one to construct joint probability distributions for incompatible observables. The existence of a bona fide joint probability distribution for the incompatible observables occurring in the EPRB experiments would entail that Bell's inequalities can be satisfied, and hence that the mathematical basis for the nonlocal effects would disappear. This relult would apparently allow one to eliminate the need for nonlocal effects by considering experiments of this new kind

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

    1991-01-01

    Positron emission tomography (PET) is a non-invasive diagnostic imaging technique requiring rapid and reliable radiopharmaceutical production. Automated systems offer a host of potential advantages over manually or remotely operated apparatus, including reduced personnel requirements, lower radiation exposure to personel, reliable yields, and reproducible product purity. However, the burden of routine radiopharmaceutical production most often remains a labor-intensive responsibility of highly trained radiochemists. In order to ease the transition between manual, remote-controlled, and computer-controlled radiochemical synthesis, an electronic toolbox with graphical user interface was developed as a generic process control system compatible with a variety of common radiochemical operations. This work is specifically aimed to make automated techniques more accessible by emphasizing the similarities between manual and automated chemistry and by minimizing the computer programming effort required. This paper discusses the structural elements of the electronic toolbox approach to radiochemistry process control, and its ramifications for the designers and end-users of automated synthesizers

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

    The 50-year history of the U.S. high-level nuclear waste program claims not a single kilogram of waste disposed. Now more than ever this matter demands a solution, for economic and other reasons. There are many things that must be corrected if the waste program is to ever turn the corner. There must be established an independent public corporation with a single mandate: high-level nuclear waste disposal. At the top, it would have as structure a board of directors made up of individuals that want the disposal initiative to succeed, such as utility CEOs, utility regulatory commissioners, congressional and/or presidential sppointees, and others vitally concerned with thes progress. Decisions would not be subject to the political interests or pressure for the DOE, the Secretary or the Administration. The competiton for authorization among DOE divisions must be eliminated. And the vital need for interim storage must be met. An independent, accountable agency with a properly designed management structure is at the heart of the solution

    1997-01-01

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

    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.

    After a brief description of the goal of Fermi National Accelerator Laboratory (Fermilab) this paper poses and answers three questions related to Quality Assurance (QA) at the Laboratory. First, what is the difference between 'orthodox' and 'unorthodox' QA and is there a place for 'orthodox' QA at a laboratory like Fermilab? Second, are the deeper philosophical and cultural frameworks of high-energy physics acommodating or antagonistic to an 'orthodox' QA Program? Finally, faced with the task of developing an institutional QA program for Fermilab where does one begin? The paper is based on experience with the on-going development and implementation of an institutional QA Program at Fermilab. 10 refs

    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.

    The U.S. Department of Energy has provided support to four universities and the Oak Ridge National Laboratory in order to pursue research leading to the development and deployment of advanced robotic systems capable of performing tasks that generate significant occupational radiation exposure and/or whose execution times can be reduced if performed by an automated system. The goal was to develop advanced robotic systems capable of performing surveillance, maintenance, and repair tasks in nuclear facilities and other hazardous environments. The approach to achieving the program objective was a transition from teleoperation to the capability of autonomous operation within three successive generations of robotic systems. The robotic system will always have the capability to request human assistance. The development of general purpose robots to perform skilled labor tasks in restricted environments was shown to have extensive payback in areas of energy systems (nuclear and fossil units), chemical plants, fire fighting, space operations, underwater activities, defense, and other hazardous activities. The strategy that was used to achieve the program goals in an efficient and timely manner consisted in utilizing, and advancing where required, state-of-the-art robotics technology through close interaction between the universities and the manufacturers and operators of nuclear power plants. The research effort showed that a broad range of applications for the robotic systems existed for the improved operation of nuclear reactors and in other hazardous tasks. As a consequence, each institution was able to obtain additional support from other agencies, e.g., DoD and NASA. Areas of cooperation with other nations (e.g., Japan, France, Germany) were utilized

    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.

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

  2. Malformation/dysplasia syndrome (neural tube defect, hypospadias neuroblastoma) associated with an extra dicentric marker chromosome 15 ({open_quotes}inversion duplication 15{close_quotes})

    Extra dicentric 15 marker chromosomes are associated with variable degrees of mental retardation but not major structural birth defects. We have studied a unique patient, a male infant who was prenatally diagnosed with lumbar meningomyelocele and an extra pseudodicentric marker chromosome: 47,XY,+psu dic(15)t(15;15)(?q12,?q12)mat. Hairy ears and a coronal hypospadias were noted at birth. At three months of age, a stage I thoracic neuroblastoma was primarily resected. Tumor cells, skin fibroblasts and peripheral blood lymphocytes contained the dicentric 15. The mother is mosaic for the marker chromosome. Fluorescence in situ hybridization (FISH) studies using a classic 15 satellite probe (D15Z1 [Oncor]) confirmed the presence of 2 number 15 centromeres in the marker. The marker is felt to be the result of a translocation rather than an inverted duplication because the G-band morphology of the short arm/satellite complexes differ from one another, implying that the arms originate from 2 different number 15s. FISH analysis using cosmid probes for the Prader-Willi/Angelman critical region (D15S11 and GABRB3 [Oncor]) revealed 2 copies of this region, indicating that these loci are duplicated in the marker. Although some features of the patient`s phenotype such as developmental delay and hypotonia have been associated with dicentric chromosome 15 markers, this is the first malformation/dysplasia syndrome or neuroblastoma reported to our knowledge. The association of neuroblastoma with chromosome 15 aberrations in this case provides speculation as to the role of chromosome 15 loci in cell division control.

    A short review of the different approaches to the justification of the Neglect of Diatomic Differential Overlap in the basis of symmetrically orthogonalized basis functions is given. Brown and Roby employed the binomial expansion for the approximation of the inverse square root of the overlap matrix. For some overlap matrices, this expansion does not converge. The always-convergent power series given by Chandler and Grader provides a worse second-order approximation in comparison with the second-order binomial expansion. 9 refs

    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

    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.

    Natural nuclear fission reactors are only known in two uranium deposits in the world, the Oklo and Bangombe deposits of the Franceville basin: Gabon. Since 1982, five new reactor zones have been discovered in these deposits and studied since 1989 in a cooperative European program. New geological, mineralogical, and geochemical studies have been carried out in order to understand the behavior of the actinides and fission products which have been stored in a geological environment for more than 2.0 Ga years. The Franceville basin and the uranium deposits remained geologically stable over a long period of time. Therefore, the sites of Oklo and Bangombe are well preserved. For the reactors, two main periods of actinide and radionuclides migration have been observed: during the criticality, under P-T conditions of 300 bars and 400-500 degrees C, respectively, and during a distention event which affected the Franceville basin 800 to 900 Ma ago and which was responsible for the intrusion of dolerite dikes close to the reactors. New isotopic analyses on uranium dioxides, clays, and phosphates allow us to determine their respective importance for the retention of fission products. The UO 2 matrix appears to be efficient at retaining most actinides and fission products such as REEs, Y, and Zr but not the volatile fission products (Cd, Cs, Xe, and Kr) nor Rb, Sr, and Ba. Some fissiogenic elements such as Mo, Tc, Ru, Rh, Pd, and Te could have formed metallic and oxide inclusion in the UO 2 matrix which are similar to those observed in artificial spent fuel. Clays and phosphate minerals also appear to have played a role in the retention of fissiogenic REEs and also of Pu. 82 refs., 21 figs., 12 tabs

  12. Rolling and slipping down Galileo close-quote s inclined plane: Rhythms of the spheres

    1996-01-01

    In ''Two New Sciences'' (TNS) Galileo presents a number of theorems and propositions for smooth solid spheres released from rest and rolling a distance d in time t down an incline of height H and length L. We collect and summarize his results in a single grand proportionality P: d 1 /d 2 =(t 2 1 /t 2 2 )(H/L) 1 /(H/L) 2 . (P) From TNS it is clear that what we call P is assumed by Galileo to hold for all inclinations including vertical free fall with H/L=1. But in TNS he describes only experiments with gentle inclinations H/L 1 while rolling down a gentle incline is deflected so as to be launched horizontally with speed v 1 into a free fall orbit discovered by Galileo to be a parabola. The measured horizontal distance X 2 traveled in this parabolic orbit (for a given vertical distance fallen to the floor) was smaller than he expected, by a factor 0.84. But that is exactly what we (moderns) expect, since we know that Galileo did not appreciate the difference between rolling without slipping, and slipping on a frictionless surface

    Full Text Available This study investigates the influence which audit firm size exerts on the market value per share of companies in Nigeria. Based on a sample of 342 companies – year observations from the NSE and applying audit firm size as a measure, comprehensive multivariate analyses were conducted on archival data covering 2006 – 2011. The result showed that audit firm size exerts significant relationship and significantly influences market price per share of the companies in the sample. It is suggested that companies in Nigeria should improve their earnings quality only through sales growth and cost control strategies and present distinct reports on earnings quality. Furthermore, company auditors should issue Integrated Audit Quality Assurance Reports based on earnings quality assessment, statutorily backed by earnings monitoring of companies in Nigeria while regulatory agencies should issue authoritative codes of best practice in Nigeria.

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

    Adhering to the lore that vorticity is a critical ingredient of fluid turbulence, a triad of coupled helicity (vorticity) states of the incompressible Navier-Stokes fluid are followed. Effects of the remaining states of the fluid on the triad are then modeled as a simple driving term. Numerical solution of the equations yield attractors that seem strange and chaotic. This suggests that the unpredictability of nonlinear fluid dynamics (i.e., turbulence) may be traced back to the most primordial structure of the Navier-Stokes equation; namely, the driven triadic interaction. copyright 1996 The American Physical Society

    The aim of this study was to evaluate the safety and efficacy of medical thoracoscopy through a single port [single-port medical thoracoscopy (S-MT)] for the treatment of empyema thoracis in its early stages. We performed a retrospective analysis reviewing the medical records of 84 patients referred for empyema and treated by medical thoracoscopy at our Thoracic Departments from January 2001 until November 2014. S-MT was performed under local anesthesia with neuroleptoanalgesia and spontaneous breathing using a single 1-cm incision for debridement and lavage of the pleural cavity. A total of 84 patients underwent S-MT for pleural empyema stage I (9 patients, 10.7%) or II (75 patients, 89.3%). Median age was 61.8 years (range, 18 to 84 y). Male to female ratio was 3.76. Surgery was performed 5 to 26 days after the onset of symptoms. Macroscopically complete debridement of the pleural cavity was achieved in 71 patients (84.5% of cases). The rest 15.5% of cases required video-assisted thoracoscopic surgery or open decortication due to trapped-lung syndrome. Median operation time was 45 minutes (range, 30 to 94 min). No intraoperative complications occurred. In-hospital mortality was zero, whereas in-hospital morbidity rate was 16.7%. Median hospital stay was 7.8 days (range, 3 to 18 days). Recurrence rate was 4.8% as 4 patients experienced a relapse of empyema. It seems that S-MT is a minimally invasive, safe and effective procedure for the treatment of pleural empyema with very good results in early stages of the disease and reduced time of hospital stay.

    Full Text Available In order to ensure a sustainable development of an entity, a sustainability accounting report, trustfulness and proper made is mandatory for financial users. As a fact, the entities have to reveal social and environment information in order to increase the creditworthiness in the activity they realized. The purpose of this research is to point out how the sustainability accounting report influences the financial performance of the companies, by quantifying the social and environment elements in a score variable. The analysis is done upon the societies that are listed on the first category of Bucharest Stock of Exchange and tries to identity the way through which sustainable development can be ensured. The results are based on a linear regression model and find a direct positive correlation between the score variable and the financial performance of the companies

    1998-01-01

    I present the history of the discovery of the Upsilon (Υ) particle (the first member of the 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 Υ in November 1976 in an early phase of E288. The subsequent discovery in the spring of 1977 resulted from an upgraded E288 emdash the μμII 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 μμII 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 1998 American Institute of Physics

    In 1992, during the United Nation`s Conference on Environment and Development, held in Rio de Janeiro, the Framework Convention on Climate Change was signed. The ultimate objective of this Convention is the control and the reduction of greenhouse gas releases from human activities, to achieve stabilization of greenhouse gas concentrations in the atmosphere. The purpose of this research is to provide a reallocation of carbon dioxide important greenhouse gas, among nine countries representing the different geopolitical worldwide situations. Demographic, socioeconomic and environmental criteria have been taken into account. Some of these issues have been proposed in the international negotiating context. In order to apportion emissions the Analytic Hierarchy Process (AHP) has been used. The AHP is a multi objective decision-making technique employing a method of pairwise comparisons to rank order alternatives of a problem formulated in a hierarchic structure by computing the largest eigenvalue of the pairwise comparisons matrix. Moreover, the AHP approach enables one to deal with both quantitative and qualitative factors in a logical fashion. The findings summarize the different indicators considered representing the proposals of the parties involved in the international debate.

  16. Brain 'talks over' boring quotes: top-down activation of voice-selective areas while listening to monotonous direct speech quotations.

    Science.gov (United States)

    Yao, Bo; Belin, Pascal; Scheepers, Christoph

    2012-04-15

    In human communication, direct speech (e.g., Mary said, "I'm hungry") is perceived as more vivid than indirect speech (e.g., Mary said that she was hungry). This vividness distinction has previously been found to underlie silent reading of quotations: Using functional magnetic resonance imaging (fMRI), we found that direct speech elicited higher brain activity in the temporal voice areas (TVA) of the auditory cortex than indirect speech, consistent with an "inner voice" experience in reading direct speech. Here we show that listening to monotonously spoken direct versus indirect speech quotations also engenders differential TVA activity. This suggests that individuals engage in top-down simulations or imagery of enriched supra-segmental acoustic representations while listening to monotonous direct speech. The findings shed new light on the acoustic nature of the "inner voice" in understanding direct speech. Copyright © 2012 Elsevier Inc. All rights reserved.

    1996-01-01

    For the first time fractional Stark state selective electric field ionization of very high-n (n approx-gt 250) molecular Rydberg states is observed. An open-quote open-quote offset close-quote close-quote electric pulse selectively ionizes the more fragile open-quote open-quote red close-quote close-quote (down shifted in energy) Stark states. The more resilient open-quote open-quote bluer close-quote close-quote, or up-shifted, ones survive and are shifted down in energy upon application of a second (open-quote open-quote probe close-quote close-quote) pulse of opposite direction (diabatic Stark states close-quote inversion). Hence, even for smaller probe than offset fields ionization is observed. The offset/probe ratio allows one to control spectral peak shapes in zero-kinetic-energy photoelectron spectroscopy. copyright 1995 The American Physical Society

    After an overview of the production of electricity from nuclear energy and of its risks, the author discusses the issue of nuclear safety by distinguishing the different points of view, by describing the different levels between a severe and a major accident, and by recalling the statements made by the ASN and the IRSN on this issue. He describes the various reasons and consequences of accidents: types of accidents which could result in a core fusion, the containment failure as the major accident. He discusses the questions and comments about major issues like: strength of reactor vessels, hydrogen explosion, water vapour explosion, corium crossing the concrete sill plate, corium recovery, MOX as an aggravating situation for safety. In the last part, the author discusses the global assessment of a risk of a nuclear accident: probabilities and occurrences, significant accidents on PWRs, premonitory analysis, demonstration of nuclear safety

    After an overview of electricity production from nuclear energy and of its risks, this report first describes the responsibilities in the field of nuclear safety: main responsibilities, role of the ASN and IRSN, responsibility of the government and role of the Parliament. In the second part, the author identifies and discusses examples of inadequacies in the definition of responsibilities in different respects: practice of responsibility of control of nuclear safety, ambiguity about the transfer of responsibilities in a situation of emergency, management of modifications in basic nuclear installations, extension of the operation duration of nuclear power plants, operation duration and decennial inspections, shutdown and definitive shutdown of an electronuclear reactor. In the final part, the author makes some propositions and recommendations regarding the responsibility of political authorities, independence, transparency and democracy

    Capuzzi, F.; Mahaux, C.

    1996-01-01

    Feshbach close-quote s projection operator formalism is extended to the description of the self-energy. This necessitates the introduction of open-quote open-quote extended close-quote close-quote projection operators. They act within an open-quote open-quote extended close-quote close-quote Hilbert space in which the number of nucleons is not fixed. The compact formula derived for the self-energy is formally similar to Feshbach close-quote s original expression of the open-quote open-quote generalized close-quote close-quote optical-model potential. The theory is formulated in the nuclear case, but it also applies to atomic systems. It covers both the open-quote open-quote retarded close-quote close-quote and the open-quote open-quote time-ordered close-quote close-quote Green close-quote s functions, and the open-quote open-quote proper close-quote close-quote and open-quote open-quote improper close-quote close-quote self-energies. It is first worked out in a stationary formalism, in order to better exhibit its analogy with Feshbach close-quote s original theory of the generalized optical-model potential. The main results are then also derived in a time-dependent framework. It is shown that, in finite systems, Dyson close-quote s equation does not uniquely determine the self-energy, in contrast to common assumption. However, the difference between the various possibilities has little practical consequence. We exhibit the relationship between the present approach and a recent open-quote open-quote configuration interaction formulation of the Dyson equation.close-quote close-quote Contact is also established with the open-quote open-quote linked-cluster close-quote close-quote perturbation expansion of the self-energy in powers of the strength of the nucleon endash nucleon interaction.

    The necessity of establishing the traceability of dose measurement in brachytherapy 192 Ir sources is realized by physicians and researchers in the medical field. Standard sources of various shapes such as open-quotes hairpin,close quotes open-quotes single pin,close quotes open-quotes thin wire,close quotes and open-quotes seedclose quotes for calibrating ionization chambers in hospitals are being demanded. Nominal activities of not only these source products but also the standard sources have been so far specified by open-quotes apparentclose quotes values. Determination of open-quotes absoluteclose quotes activity by an established means such as 4pi-beta-gamma coincidence counting is not practical because quantitative dissolution of metallic iridium is very difficult. We tried to determine the open-quotes absoluteclose quotes activity by a calorimetric method in a fully nondestructive way

    We examine (3+1)-dimensional QED quantized in the open-quote open-quote front form close-quote close-quote with finite open-quote open-quote volume close-quote close-quote regularization, namely, in discretized light-cone quantization. Instead of the light-cone or Coulomb gauges, we impose the light-front Weyl gauge A - =0. The Dirac method is used to arrive at the quantum commutation relations for the independent variables. We apply open-quote open-quote quantum-mechanical gauge fixing close-quote close-quote to implement Gauss close-quote law, and derive the physical Hamiltonian in terms of unconstrained variables. As in the instant form, this Hamiltonian is invariant under global residual gauge transformations, namely, displacements. On the light cone the symmetry manifests itself quite differently. copyright 1996 The American Physical Society

    The classical and quantum mechanical problem of a particle in the infinite circular well has recently surfaced in two quite different manifestations: (i) the observation of open-quote open-quote electron standing waves close-quote close-quote in circular open-quote open-quote corrals close-quote close-quote of atoms adsorbed on surfaces and (ii) as a benchmark example of an integrable system for comparison to the classical and quantum chaotic behavior of the open-quote open-quote stadium billiards close-quote close-quote problem. Motivated by this, we review the quantum and classical probability distributions for both position and momentum for this familiar problem, focusing on the visualization of the quantum wave functions and classical trajectories as well as the semiclassical connections between the two. copyright 1996 American Association of Physics Teachers

    We discuss duality in N=1 SUSY gauge theories in Seiberg close-quote s conformal window, 3N c /2 f c . The close-quote t Hooft consistency conditions, the basic tool for establishing the infrared duality, are considered taking into account higher order α corrections. The conserved (anomaly-free) R current is built to all orders in α. Although this current contains all orders in α the close-quote t Hooft consistency conditions for this current are shown to be one loop. This observation thus justifies Seiberg close-quote s matching procedure. We also briefly discuss the inequivalence of the open-quote open-quote electric close-quote close-quote and open-quote open-quote magnetic close-quote close-quote theories at short distances. copyright 1996 The American Physical Society

    One of the advantages of the TOUGH/TOUGH2 (Pruess, 1987 and 1991) is the modeling using {open_quotes}free shape{close_quotes} polygonal blocks. However, the treatment of three-dimensional information, particularly for TOUGH/TOUGH2 is not easy because of the {open_quotes}free shape{close_quotes} polygonal blocks. Therefore, we have developed a database named {open_quotes}GEOBASE{close_quotes} and a pre/post-processor named {open_quotes}GEOGRAPH{close_quotes} for TOUGH/TOUGH2 on engineering work station (EWS). {open_quotes}GEOGRAPH{close_quotes} is based on the ORACLE{sup *1} relational database manager system to access data sets of surface exploration (geology, geophysics, geochemistry, etc.), drilling (well trajectory, geological column, logging, etc.), well testing (production test, injection test, interference test, tracer test, etc.) and production/injection history.{open_quotes}GEOGRAPH{close_quotes} consists of {open_quotes}Pre-processor{close_quotes} that can construct the three-dimensional free shape reservoir modeling by mouse operation on X-window and {open_quotes}Post-processor{close_quotes} that can display several kinds of two/three-dimensional maps and X-Y plots to compile data on {open_quotes}GEOBASE{close_quotes} and result of TOUGH/TOUGH2 calculation.

    Full Text Available A reforma mais profunda ocorrida nas universidades públicas na última década diz respeito à introdução de programas de ação afirmativa, para ampliar as oportunidades de negros de ingressarem na universidade. Recentemente, está ocorrendo a preocupação de ampliar os beneficiários, incluindo os candidatos que tenham cursado o ensino médio em escolas públicas. Existe uma diversidade de programas, refletindo a autonomia das universidades em definirem, principalmente, o grupo focal e o mecanismo de favorecer os estudantes nesse grupo. Esse mecanismo pode ser o sistema de cotas ou o sistema de bônus. O sistema de cotas reserva um percentual das vagas em cada carreira para os candidatos cotistas classificados; já o bônus acresce à pontuação do candidato cotista um percentual que pode ser fixo ou variável. No caso do bônus, os beneficiários são estudantes que cursaram o ensino médio. É inevitável que haja um conflito entre eficiência e equidade na implantação de um sistema de cotas. A perda de eficiência está na seleção de candidatos com uma pontuação menor. Neste caso, a pontuação obtida no vestibular é vista como um indicador de desempenho no curso. O ganho na equidade reflete as maiores oportunidades de acesso para os cotistas. Os resultados empíricos reforçam a importância do ambiente familiar no desempenho dos candidatos. Ambiente familiar é retratado pela escolaridade paterna e pela renda familiar. O prestígio acadêmico, medido pela pontuação dos candidatos inscritos em cada carreira, também tem um comportamento expressivo e, ao que parece, representa o capital cultural exigido em cada carreira.

The program has been extended to benefit students from public schools. The reasoning behind supporting these students is to improve their opportunities to enter universities. It is important to have in mind that the decisions to start such programs were taken by the universities. As a result of the prevailing autonomy in designing and implementing these programs, there are differences among universities in the focus groups. Usually they can be black students or students from public schools. There are two mechanisms to favor the focus groups: the use of quota systems, which defines for each career the number of places to be distributed among those candidates called "cotistas" and the use of bonus, which consists of increasing, by a given percentage, the scores of all students enrolled in public schools and selected to participate in the program by needs criteria. Quota and bonus have different consequences for the selection of those to be the beneficiaries. Thus, a comparison is made between them. One fundamental argument against "cota" is the conflict between efficiency and equality. Presumably, higher scores in the entrance exams is a good indicator of learning at the university. On the other hand, equality of opportunities requires measures to increase the chances of those that otherwise would fail. The empirical work to explain the scores in the entrance exams calls the attention to the importance of the family status, which includes family income and parent's education level. Also, the choice of the career is important to explain the performance of the candidate. The students which chose the most prestigious courses have higher chances of being approved at the entrance exams. The possible correlation among the family variables, including the career prestige, is not detected. Regarding the school variables, only night classes are statistically and negatively significant to explain the score at the entrance exam.

    We present a fully analytical approach to the study of the confinement and stability of open-quote open-quote Crystalline Beams close-quote close-quote in storage rings, in terms of such fundamental accelerator concepts as tune shift and stopband. We consider a open-quote open-quote Crystalline Beam close-quote close-quote consisting of substrings, arranged symmetrically around the reference trajectory, and we examine the motion of a slightly perturbed test particle on one of them. Our approach quite naturally leads to the conclusion, that (a) storage rings need to be operated below the transition energy, and (b) the open-quote open-quote Crystalline Beam close-quote close-quote has the same periodicity as the storage ring. Each open-quote open-quote Crystalline Beam close-quote close-quote has an upper and lower limit of the spacing between the ions. The upper limit is determined by condition (b), and the lower limit is set by the stability of the test particle motion around the equilibrium. copyright 1995 American Institute of Physics

    We consider a realistic example of supersymmetric grand unification based on SU(3) c xSU(3) L xSU(3) R in which the electroweak (EW) Higgs doublets are open-quote open-quote light close-quote close-quote as a consequence of the open-quote open-quote pseudo Goldstone close-quote close-quote mechanism. We discuss radiative EW breaking in this model, exploring in particular the open-quote open-quote small close-quote close-quote (order unity) and open-quote open-quote large close-quote close-quote (≅m t /m b ) tanβ regions by studying the variations of r 2 (≡μ 1,2 2 /μ 2 3 ), where μ 1,2,3 2 are the well-known MSSM parameters evaluated at the GUT scale. For |r| sufficiently close to unity the quantity tanβ can be of order unity, but the converse is not always true. copyright 1996 The American Physical Society

    A formulation of the consistent histories approach to quantum mechanics in terms of generalized observables (POV measures) and effect operators is provided. The usual notion of open-quote open-quote history close-quote close-quote is generalized to the notion of open-quote open-quote effect history.close-quote close-quote The space of effect histories carries the structure of a D-poset. Recent results of J. D.

Omngrave es close-quote logical interpretation is generalized to the present context. The result of this work considerably generalizes and simplifies the earlier formulation of the consistent effect histories approach to quantum mechanics communicated in a previous work of this author. copyright 1996 American Institute of Physics

    An attempt will be made in this talk to present various domain decomposition methods in a way that is intuitively clear and technically coherent and concise. The basic framework used for analysis is the {open_quotes}parallel subspace correction{close_quotes} or {open_quotes}additive Schwarz{close_quotes} method, and other simple technical tools include {open_quotes}local-global{close_quotes} and {open_quotes}global-local{close_quotes} techniques, the formal one is for constructing subspace preconditioner based on a preconditioner on the whole space whereas the later one for constructing preconditioner on the whole space based on a subspace preconditioner. The domain decomposition methods discussed in this talk fall into two major categories: one, based on local Dirichlet problems, is related to the {open_quotes}substructuring method{close_quotes} and the other, based on local Neumann problems, is related to the {open_quotes}Neumann-Neumann method{close_quotes} and {open_quotes}balancing method{close_quotes}. All these methods will be presented in a systematic and coherent manner and the analysis for both two and three dimensional cases are carried out simultaneously. In particular, some intimate relationship between these algorithms are observed and some new variants of the algorithms are obtained.

    Jenkins-Smith, H.C.; Pratt, D.A.; Bassett, G.W. Jr.

    1994-01-01

    The juxtaposition of public values, trust, and beliefs is at the core of policy-making in democratic political systems, and an accurate understanding of nuclear politics requires that researchers untangle and carefully think about the web of psychological and social influences that shape citizens' preferences. In this paper, we offer some tentative answers about several pieces of the trust open-quotes puzzleclose quotes. First, we reconsider what is meant by open-quotes trustclose quotes and how it is to be measured. We then use telephone survey data to explore the relationship between trust and citizens' nuclear policy preferences. The data lend support to the conclusion that trust is more mutable than previous research has shown, and besides the traditional measure of competence includes aspects of believability and fiduciary competence. The data further indicate that it is a mistake to think in terms of a single open-quotes publicclose quotes when exploring the link between trust and nuclear policies. A number of dissimilar open-quotes publicsclose quotes based on shared open-quotes worldviewsclose quotes or political cultures are apparent in the data analyzed here. These open-quotes publicsclose quotes appear to think about trust differently from one another and rely on different dimensions of trust when determining nuclear policy preferences. Policy-makers must recognize the different open-quotes publicsclose quotes coexisting within the U.S. nuclear policy arena, and the relative import that these publics place on different dimensions of trust

    We study environmentally induced decoherence of an electromagnetic field in a homogeneous, linear, dielectric medium. We derive an independent oscillator model for such an environment, which is sufficiently realistic to encompass essentially all linear physical optics. Applying the open-quote open-quote predictability sieve close-quote close-quote to the quantum field, and introducing the concept of a open-quote open-quote quantum halo,close-quote close-quote we recover the familiar dichotomy between background field configurations and photon excitations around them. We are then able to explain why a typical linear environment for the electromagnetic field will effectively render the former classically distinct, but leave the latter fully quantum mechanical. Finally, we suggest how and why quantum matter fields should suffer a very different form of decoherence. copyright 1996 The American Physical Society

    Kabir, P.K.; Pilaftsis, A.

    1996-01-01

    The basic requirement that, in quantum theory, the time evolution of any state is determined by the action of a unitary operator, is shown to be the underlying cause for certain open-quote open-quote exact close-quote close-quote results that have recently been reported about the time dependence of transition rates in quantum theory. Departures from exponential decay, including the open-quote open-quote quantum Zeno effect,close-quote close-quote as well as a theorem by Khalfin about the ratio of reciprocal transition rates, are shown to follow directly from such considerations. At sufficiently short times, unitarity requires that reciprocity must hold, independent of whether T invariance is valid. If T invariance does not hold, unitarity restricts the form of possible time dependence of reciprocity ratios. copyright 1996 The American Physical Society

    1993-01-01

    In the wake of seven public open-quotes work-shopsclose quotes held around the country over the past several months, the Nuclear Regulatory Commission (NRC) is preparing to develop radiological criteria for decommissioning nuclear power plants. The criteria will apply to plants that operate for their normal lifespan, those that shut down prematurely, as well as a range of other NRC-licensed facilities, including materials licensees, fuel reprocessing and fabrication plants, and independent spent fuel storage installations. The criteria have been years in the making, and their progress is being monitored closely by the Environmental Protection Agency (EPA), which shares with the NRC the authority to regulate radiological hazards. Both agencies have made abortive attempts to promulgate standards in the past. The EPA's most recent proposal, dating from 1986, has yet to reach the final rule stage. The NCRC's 1990 policy statement, open-quotes Below Regulatory Concern,close quotes was overturned by the Energy Policy Act of 1992, a setback that prompted the Commission's call for open-quotes enhanced participatory rulemakingclose quotes-a.k.a., public meetings-last December.

  20. Quantum field kinetics of QCD: Quark-gluon transport theory for light-cone-dominated processes

    International Nuclear Information System (INIS)

    Geiger, K.

    1996-01-01

    A quantum-kinetic formalism is developed to study the dynamical interplay of quantum and statistical-kinetic properties of nonequilibrium multiparton systems produced in high-energy QCD processes. The approach provides the means to follow the quantum dynamics in both space-time and energy-momentum, starting from an arbitrary initial configuration of high-momentum quarks and gluons. Using a generalized functional integral representation and adopting the open-quote open-quote closed-time-path close-quote close-quote Green function techniques, a self-consistent set of equations of motions is obtained: a Ginzburg-Landau equation for a possible color background field, and Dyson-Schwinger equations for the two-point functions of the gluon and quark fields. By exploiting the open-quote open-quote two-scale nature close-quote close-quote of light-cone-dominated QCD processes, i.e., the separation between the quantum scale that specifies the range of short-distance quantum fluctuations, and the kinetic scale that characterizes the range of statistical binary interactions, the quantum field equations of motion are converted into a corresponding set of open-quote open-quote renormalization equations close-quote close-quote and open-quote open-quote transport equations.close-quote close-quote The former describe renormalization and dissipation effects through the evolution of the spectral density of individual, dressed partons, whereas the latter determine the statistical occurrence of scattering processes among these dressed partons. The renormalization equations and the transport equations are coupled, and, hence, must be solved self-consistently. This amounts to evolving the multiparton system, from a specified initial configuration, in time and full seven-dimensional phase space, constrained by the Heisenberg uncertainty principle.

    International Nuclear Information System (INIS)

    1994-01-01

    Studies on the public perception of risks indicate that: (1) The most feared risks, together with open-quotes AIDSclose quotes and open-quotes crimeclose quotes, are those related to open-quotes nuclear accidentsclose quotes and open-quotes nuclear wasteclose quotes, which are almost as dreadful as open-quotes nuclear warclose quotes whereas, open-quotes nuclear power productionclose quotes raises less concern, almost comparable to that of other social risks. (2) Low probability, high consequence risks are those of most concern. Scarce consideration is given by the public to the likelihood of occurrence. The management strategies for fusion waste should be presented taking into account the previous statements. Sensible items are: (1) Planned waste management procedures should be describe in a well detailed fashion, indicating the aim of complying with conservative limits of environmental impact. (2) The build-up of optimistic thoughts on the complete lack of potential hazard in fusion waste as well as the opposite opinion of little or no progress at all by referring to fission waste should be avoided. (3) The hazards related to fission waste should not be over emphasized. It should be stated instead that studies on this waste have produced effective handling and segregation concepts, which are being progressively applied even to conventional waste in order to reduce risks which were not perceived before. This mature and well proven technology will be applied where pertinent to fusion waste too

  5. Assigning spectra of chaotic molecules with diabatic correlation diagrams

    International Nuclear Information System (INIS)

    Rose, J.P.; Kellman, M.E.

    1996-01-01

    An approach for classifying and organizing spectra of highly excited vibrational states of molecules is investigated. As a specific example, we analyze the spectrum of an effective spectroscopic fitting Hamiltonian for H 2 O. In highly excited spectra, multiple resonance couplings and anharmonicity interact to give branching of the N original normal modes into new anharmonic modes, accompanied by the onset of widespread chaos. The anharmonic modes are identified by means of a bifurcation analysis of the spectroscopic Hamiltonian. A diabatic correlation diagram technique is developed to assign the levels with approximate open-quote open-quote dynamical close-quote close-quote quantum numbers corresponding to the dynamics determined from the bifurcation analysis. The resulting assignment shows significant disturbance from the conventional spectral pattern organization into sequences and progressions. The open-quote open-quote dynamical close-quote close-quote assignment is then converted into an assignment in terms of open-quote open-quote nominal close-quote close-quote quantum numbers that function like the N normal mode quantum numbers at low energy. The nominal assignments are used to reconstruct, as much as possible, an organization of the spectrum resembling the usual separation into sequences and progressions. copyright 1996 American Institute of Physics

  6. Production of microbunched beams of very highly charged ions with an electron beam ion source

    International Nuclear Information System (INIS)

    Stoeckli, M.P.

    1998-01-01

    Electron beam ion sources produce very highly charged ions most efficiently in a batch mode as the confinement time can be directly optimized for the production of the desired charge state. If, after confinement, the voltage of the ion-confining downstream dam is lowered rapidly, all ions escape and form an ion beam pulse with a length of a few tens of μs. Raising the main trap voltage while maintaining a constant dam voltage in a open-quotes spill-over expulsionclose quotes reduces the energy spread of the expelled ions. The longer time periods of open-quotes slow-,close quotes open-quotes leaky batch mode-,close quotes and open-quotes direct current (dc) batch mode-close quotes expulsions allow for increasing the ion beam duty cycle. Combining the rapid expulsion with one of the latter methods allows for the expulsion of the ions of a single batch in many small microbunches with variable intervals, maintaining the low energy spread and the increased duty cycle of slow expulsions. Combining the open-quotes microbunchingclose quotes with open-quotes dc batch mode productionclose quotes and a multitrap operation will eventually allow for the production of equally intense ion bunches over a wide range of frequencies without any deadtime, and with minimal compromise on the most efficient production parameters. copyright 1998 American Institute of Physics

    The convective and potential variational principles that can be used for alternative derivations of the same natural relativistic generalisation of the standard Landau theory of perfect superfluid dynamics are both characterised by the feature that, instead of attributing special importance to a partition in terms of certain non-conserved open-quotes superfluidclose quotes and open-quotes normalclose quotes current vectors j v s and j v N they accord a much more prominent role to certain open-quotes particleclose quotes and open-quotes thermalclose quotes momentum convectors μ v and Θ v of which the latter in particular has been unduly neglected in traditional discussions.

  12. Chern-Simons field theory of two-dimensional electrons in the lowest Landau level

    International Nuclear Information System (INIS)

    Zhang, L.

    1996-01-01

    We propose a fermion Chern-Simons field theory describing two-dimensional electrons in the lowest Landau level. This theory is constructed with a complete set of states, and the lowest-Landau-level constraint is enforced through a δ functional described by an auxiliary field λ. Unlike the field theory constructed directly with the states in the lowest Landau level, this theory allows one, utilizing the physical picture of open-quote open-quote composite fermion,close-quote close-quote to study the fractional quantum Hall states by mapping them onto certain integer quantum Hall states; but, unlike its application in the unconstrained theory, such a mapping is sensible only when interactions between electrons are present. An open-quote open-quote effective mass,close-quote close-quote which characterizes the scale of low energy excitations in the fractional quantum Hall systems, emerges naturally from our theory. We study a Gaussian effective theory and interpret physically the dressed stationary point equation for λ as an equation for the open-quote open-quote mass renormalization close-quote close-quote of composite fermions. copyright 1996 The American Physical Society

    We prove a new result limiting the amount of accessible information in a quantum channel. This generalizes Kholevo close-quote s theorem and implies it as a simple corollary. Our proof uses the strong subadditivity of the von Neumann entropy functional S(ρ) and a specific physical analysis of the measurement process. The result presented here has application in information obtained from open-quote open-quote weak close-quote close-quote measurements, such as those sometimes considered in quantum cryptography. copyright 1996 The American Physical Society

    The purpose of the Year 14 UCETF project was to design and construct a residential structure that could serve as a demonstration facility, training site, and testing and monitoring laboratory for issues related to the implementation of sustainable building practices and materials. The Model Home Project builds on the previous and existing efforts, partially funded by the UCETF, of the City of Austin Green Builder Program to incorporate sustainable building practices into mainstream building activities. The Green Builder Program uses the term {open_quotes}green{close_quotes} as a synonym for sustainability. In the research and analysis that was completed for our earlier reports in Years 12 and 13, we characterized specific elements that we associate with sustainability and, thus, green building. In general, we refer to a modified life cycle assessment to ascertain if {open_quotes}green{close_quotes} building options reflect similar positive cyclical patterns found in nature (i.e. recyclability, recycled content, renewable resources, etc.). We additionally consider economic, human health and synergistic ecological impacts associated with our building choices and characterize the best choices as {open_quotes}green.{close_quotes} Our ultimate goal is to identify and use those {open_quotes}green{close_quotes} materials and processes that provide well for us now and do not compromise similar benefits for future generations. The original partnership developed for this project shifted during the year from a project stressing advanced (many prototypical) {open_quotes}green{close_quotes} building materials and techniques in a research and demonstration context, to off-the-shelf but underutilized {open_quotes}green{close_quotes} materials in the practical social context of using {open_quotes}green{close_quotes} technologies for low income housing. That project, discussed in this report, is called the Green Habitat Learning Project.

    1996-02-01

    In our last article, we discussed determination and possible causes leading to frozen pipes in the heating system. We now turn to the matter of dealing with such freeze-ups. There are two major categories of frozen heating systems. The first and worst we can label the {open_quotes}Floridian Flew{close_quotes} type, when the usual occupants have taken off for warmer climates. The second is the {open_quotes}Howcudit {open_quote}B{close_quote} virus,{close_quotes} which occurs to normal people under an unusual Arctic Attack right while they are living there. Regarding the first, I never cease to be amazed how folks can just up and leave their house for three days to three months without making proper arrangements for monitoring the temperature of their home during their absence. There are a frightening number of humanoids out there, who either lack a minimal presence of common sense, or who are terrible gamblers. The amazing thing is that some of these folks wouldn`t even gamble a postage stamp on a magazine sweepstakes, but still will gamble the contents of their home by driving off for two weeks at Disneyland in the middle of January without ever making any provision for assuring that their house doesn`t freeze up while they are away. The {open_quotes}Howcudit {open_quote}B{close_quote}{close_quotes} type is not nearly as devasting as the {open_quotes}Floridian Flew.{close_quotes} Imagine coming home to an icy cold house after flying in from the sunny beaches of some tropical paradise.

    1996-01-01

    A new technology has been implemented using an open-quotes active-detectorclose quotes comprised of two computed radiography (CR) imaging plates in a sandwich geometry for dual-energy radiography. This detector allows excellent energy separation, short exposure time, and high signal to noise ratio (SNR) for clinically robust open-quotes bone-onlyclose quotes and open-quotes soft-tissue onlyclose quotes images with minimum patient motion. Energy separation is achieved by two separate exposures at widely different kVp's: the high energy (120 kVp + 1.5 mm Cu filter) exposure is initiated first, followed by a short burst of intense light to erase the latent image on the front plate, and then a 50 kVp (low energy) exposure. A personal computer interfaced to the x-ray generator, filter wheel, and active detector system orchestrates the acquisition sequence within a time period of 150 msec. The front and back plates are processed using a CR readout algorithm with fixed speed and wide dynamic range. open-quotes Bone-onlyclose quotes and open-quotes soft-tissue onlyclose quotes images are calculated by geometric alignment of the two images and application of dual energy decomposition algorithms on a pixel by pixel basis. Resultant images of a calibration phantom demonstrate an increase of SNR 2 / dose by ∼73 times when compared to a single exposure open-quotes passive-detectorclose quotes comprised of CR imaging plates, and an ∼8 fold increase compared to a screen-film dual-energy cassette comprised of different phosphor compounds. In conclusion, dual energy imaging with open-quotes active detectorclose quotes technology is clinically feasible and can provide substantial improvements over conventional methods for dual-energy radiography

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

  20. Set theory and physics

    Svozil, K. [Univ. of Technology, Vienna (Austria)

    1995-11-01

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

    1997-07-01

    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.

  2. MARKET-MAKING STRATEGY IN THE SYSTEM OF ALGORITHMIC HIGH-FREQUENCY TRADING

    2014-01-01

    Full Text Available Market maker is the most important participant of modern exchange trading, it provides the increase of market liquidity and reduces the difference between bid and ask (spread. The paper presents automatic market-making strategy for quoting of options and other kinds of financial instruments on electronic markets. Quotes are based on theoretical pricing which is a resource-intensive task. Presented algorithmic optimizations, in particular quotes caching and smoothing of underlying asset price oscillation, give the possibility up to four times boost for quote modify scenario on real market data. Mechanism of quotes caching precalculates quotes in certain diapason around current underlying price. If underlying price changes within the diapason, algorithm sends already filled message for quote modification, instead of new complex computation. Smoothing of underlying asset price oscillation prevents permanent moving of the diapason and reacts only on significant market moving. A size of caching diapason which provides optimal correlation between speed of quotes modification and resource consumption has been defined experimentally (40 elements. In case of quoting 36 options on Eurex Exchange an average delay between underlying price change and quote modification is 277 usec. The measurements were carried out on the Sun X4170 M3: CPU(s: 2xXeon 2.9GHz RAM: 128 GB server under Solaris 10 operating system. Obtained results correspond to modern market-making requirements. The developed strategy is used by big European banks and trading firms.

    1991-01-01

    While carrying out their central responsibility of conducting an environmental investigation in a high- quality, timely, and cost-effective manner, project managers also face a significant challenge due to the many inherent uncertainties associated with characterizing and remediating sites. From all aspects and considerations (health and financial risks; and technical, professional, and legal defensibility/credibility), the project manager must minimize the uncertainty associated with making decisions based on environmental data. A key objective for every project manager is to produce sufficient data of known and acceptable quality. In simple terms, the level of confidence in the gathered data directly relates to: (1) the upfront determination of the types and uses of the data needed (which drives the required quality of the data); (2) the ongoing verification that the prescribed methods by which the data are to be obtained and analyzed are being followed; and (3) the validation of the verified data to determine whether the preestablished data quality objectives have been met, therefore making the data adequate for their intended use(s). This paper focuses on the third clement of the equation for data quality, therefore implying that the first two elements (planning and verification) have been accomplished.

    Control system architecture development has followed the advances in computer technology through mainframes to minicomputers to micros and workstations. This technology advance and increasingly challenging accelerator data acquisition and automation requirements have driven control system architecture development. In summarizing the progress of control system architecture at the last International Conference on Accelerator and Large Experimental Physics Control Systems (ICALEPCS) B. Kuiper asserted that the system architecture issue was resolved and presented a open-quotes standard modelclose quotes. The open-quotes standard modelclose quotes consists of a local area network (Ethernet or FDDI) providing communication between front end microcomputers, connected to the accelerator, and workstations, providing the operator interface and computational support. Although this model represents many present designs, there are exceptions including reflected memory and hierarchical architectures driven by requirements for widely dispersed, large channel count or tightly coupled systems. This paper describes the performance characteristics and features of the open-quotes standard modelclose quotes to determine if the requirements of open-quotes non-standardclose quotes architectures can be met. Several possible extensions to the open-quotes standard modelclose quotes are suggested including software as well as the hardware architectural features

    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 caseclose quotes design has been chosen. This open-quotes no caseclose 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 linkclose quotes in the coil winding pack structure and needs to be modeled in detail. A global finite element model with smeared winding pack properties was used to study the CS magnet structural behavior. The structural analysis results and peak stresses will be presented

  9. Classical methods for interpreting objective function minimization as intelligent inference

    Energy Technology Data Exchange (ETDEWEB)

    Golden, R.M. [Univ. of Texas, Dallas, TX (United States)

    1996-12-31

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

    Rosen, M.D.

    1993-01-01

    The author presents scaling laws for the behavior of hohlraums that are somewhat more complex than a simple sphere or cylinder. In particular the author considers hohlraums that are in what has become known as a open-quotes primaryclose quotes open-quotes secondaryclose quotes configuration, namely geometries in which the laser is absorbed in a primary region of a hohlraum, and only radiation energy is transported to a secondary part of the hohlraum that is shielded from seeing the laser light directly. Such hohlraums have been in use of late for doing LTE opacity experiments on a sample in the secondary and in recently proposed open-quotes shimmedclose quotes hohlraums that use gold disks on axis to block a capsule's view of the cold laser entrance hole. The temperature/drive of the secondary, derived herein, scales somewhat differently than the drive in simple hohlraums

    Noyes, H.P.

    1995-01-01

    The author continues the discussion started last year. By now three potentially divergent research programs have surfaced in ANPA: (1) the Bastin-Kilmister understanding of the combinatorial hierarchy (Clive's open-quotes Menshevikclose quotes position); (2) the author's bit-string open-quotes Theory of Everythingclose quotes (which Clive has dubbed open-quotes Bolshevikclose quotes); (3) Manthey's cycle hierarchy based on co-occurrence and mutual exclusion that Clive helped him map onto quaternions (as an yet unnamed heresy?). Unless a common objective can be found, these three points of view will continue to diverge. The authors suggests the reconstruction of relativistic quantum mechanism (RRQM) as a reasonable, and attainable, goal that might aid convergence rather than divergence

    1998-05-01

    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 fingerprintclose quotes or open-quotes tagclose 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-lowclose 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

    The break preclusion concept is based on {open_quotes}KTA rules{close_quotes}, {open_quotes}RSK guidelines{close_quotes} and {open_quotes}Rahmenspeziflkation Basissicherheit{close_quotes}. These fundamental rules containing for example requirements on material, design, calculation, manufacturing and testing procedures are explained and the technical realisation is shown by means of examples. The proof of the quality of these piping systems can be executed by means of fracture mechanics calculations by showing that in every case the leakage monitoring system already detect cracks which are clearly smaller than the critical crack. Thus the leak before break behavior and the break preclusion concept is implicitly affirmed. In order to further diminish conservativities in the fracture mechanics procedures, specific research projects are executed which are explained in this contribution.

    REMOTEC has developed a open-quotes radiation resistanceclose quotes control system under a U.S. Department of Energy Small Business Innovative Research (SBIR) contract with assistance from the University of Florida. The SBIR goal was to develop a radiation resistant mobile robot from the ANDROS family of hazardous duty mobile robots that REMOTEC manufactures. See Refs. 1 and 2 for additional SBIR results. The control system, as well as the entire ANDROS robot, was redesigned, where necessary, to withstand radiation doses in excess of 10 6 rad. Those components of the robot that could not be purchased as open-quotes radiation hardenedclose quotes were tested under standard operating conditions for determination of their open-quotes radiation resistance.close quotes The entire ANDROS robot was then assembled with these new components and tested to > 10 6 rad

    1996-01-01

    The author previously presented the basis for regulating mixed waste according to the primary hazard (either chemical or radiological) in order to avoid the inefficient practice of open-quotes dual regulationclose quotes of mixed waste. In addition to covering the technical basis, recommendations were made on how to capitalize upon a window of opportunity for implementation of a open-quotes primary hazards approachclose quotes. Some of those recommendations have been pursued and the resulting advances on the regulatory front are exciting. This paper chronicles those pursuits, presents in capsule form the massive amount of data assembled, and summarizes the changing regulatory framework. The data supports the premise that disposal of stabilized mixed waste in a low-level radioactive waste (LLW) disposal facility is protective of human health and the environment. Based on that premise, proposed regulatory changes, if finalized, will eliminate much of the open-quotes dual regulationclose quotes of mixed waste

    The term {open_quotes}Gas Processing{close_quotes} has many possible meanings and understandings. In this paper, and panel, we will be using it to generally mean the treatment of gas by methods other than those common to HVAC and Nuclear Air Treatment. This is only a working guideline not a rigorous definition. Whether a rigorous definition is desirable, or even possible is a question for some other forum. Here we will be discussing the practical aspects of what {open_quotes}Gas Processing{close_quotes} includes and how existing Codes, Standards and industry experience can, and should, apply to DOE and NRC Licensed facilities. A major impediment to use of the best engineering and technology in many nuclear facilities is the administrative mandate that only systems and equipment that meet specified {open_quotes}nuclear{close_quotes} documents are permissible. This paper will highlight some of the limitations created by this approach.

    1995-01-01

    A review of the regulatory history of the Nuclear Regulatory Commission (NRC) regulations applicable to the licensing of a geologic repository, as well as a review of NRC administrative (licensing) decisions and federal case law, support the NRC's use of simplified models, in appropriate circumstances, which provide well-documented and reasonably conservative bounding assumptions, together with the use of expert judgement, natural analogues, and other aids to supplement available information, in reaching its reasonable assurance determination whether the public health and safety will be adequately protected if the Yucca Mountain, Nevada site should be licensed for development as a geologic repository. Specific examples are provided to assist the reader to better understand how such qualitative concepts as open-quote reasonable assurance close-quote, open-quote reasonably conservative close-quote, and open-quote adequate close-quote protection are used in an administrative context to resolve technical issues

    The world of safety analysis is filled with ambiguous words: codes and standards, consequences and risks, hazard and accident, and health and safety. These words have been subject to disparate interpretations by safety analysis report (SAR) writers, readers, and users. open-quotes Principal health and safety criteriaclose quotes has been one of the most frequently misused phrases; rarely is it used consistently or effectively. This paper offers an easily understood definition for open-quotes principal health and safety criteriaclose quotes and uses systems engineering to convert an otherwise mysterious topic into the primary means of producing an integrated SAR.

    Fragrance chemistry is, together with the closely related area of flavor chemistry, one of the few domains, if not the only one, in which chemists can immediately experience structure-activity relationships. This review presents structure-odor correlations and olfactophore models for the main odor notes of perfumery: "fruity", "marine", "green", "floral", "spicy", "woody", "amber", and "musky". New trendsetters and so-called captive odorants of these notes are introduced, and recent activities and highlights in fragrance chemistry are summarized. The design of odorants, their chemical synthesis, and their use in modern perfumery is discussed. Our selection is guided and illustrated by creative fragrances, and features new odorants which encompassed current trends in perfumery. New odorants for grapefruit and blackcurrant, for galbanum, and leafy top notes are presented. Compounds with fashionable marine, ozonic, and aquatic facets are treated, as well as new odorants for classical lily-of-the-valley, rose, and jasmine accords. Compounds with sweet and spicy tonalities are also discussed, as are the most recent developments for woody notes such as sandalwood and vetiver. We conclude with musky and ambery odorants possessing uncommon or unusual structural features. Some odor trends and effects are illustrated by microencapsulated fragrance samples, and areas where there is need for the development of new synthetic materials and methodologies are pointed out. Thus, chemists are invited to explore fragrance chemistry and participate in the design and synthesis of new odorants. This review gives the latest state of the art of the subject.

These problems are analyzed in the context of the interaction between exchange floor agents. The authors then propose and test relativel...

  4. Elevated temperature tensile properties of borated 304 stainless steel: Effect of boride dispersion on strength and ductility

    International Nuclear Information System (INIS)

    Stephens, J.J.; Sorenson, K.B.; McConnell, P.

    1992-01-01

    Conventional cast and wrought (open-quotes Ingot Metallurgyclose quotes) borated 304 stainless steel has been used for a number of years in spent fuel storage applications where a combination of structural integrity and neutron criticality control are required. Similar requirements apply for materials used in transport cask baskets. However, in the high boron contents (>1.0 wt. %) which are most useful for criticality control, the conventional cast and wrought material suffers from low ductility as well as low impact toughness. The microstructural reason for these poor properties is the relatively coarse size of the boride particles in these alloys, which act as sites for crack initiation. Recently, a open-quotes premiumclose quotes grade of borated 304 stainless steel has been introduced (Strober and Smith, 1988) which is made by a Powder Metallurgy (PM) process. This material has greatly improved ductility and impact properties relative to the conventional cast and wrought product. In addition, an ASTM specification (ATSM A887) has been developed for borated stainless steel, containing 8 different material Types with respect to boron content - with the highest level (Type B7) having permissible range from 1.75 to 2.25 wt. % boron - and each Type contains two different Grades of material based on tensile and impact properties. While the ASTM specification is properties-based and does not require a specific production process for a particular grade of material, the PM material qualifies as open-quotes Grade Aclose quotes material while the conventional Ingot Metallurgy (IM) material generally qualifies as open-quotes Grade Bclose quotes material. This paper presents a comparison of the tensile properties of PM open-quotes Grade Aclose quotes material with that of the conventional IM open-quotes Grade Bclose quotes material for two selected Types (i.e., boron contents) as defined by the ASTM A887 specification: Types 304B5 and 304B7

  5. Progress toward a genotype/phenotype correlation in galactosemia

    Galactosemia is secondary to deficiency of the enzyme galactose-1-phosphate uridyl transferase (GALT). If untreated this condition results in severe neonatal symptoms and can be fatal. Most symptoms disappear upon the institution of a galactose-restricted diet. Therefore, most states in the US and many developed countries have implemented newborn screening programs for galactosemia. We have characterized thus far twelve disease-causing point mutations, four protein polymorphisms, one silent nucleotide substitution and a RFLP (restriction fragment length polymorphism) in over 200 patients. The most common galactosemia mutation, Q188R, is present on about 64% of Caucasian galactosemia alleles in the US. This mutation is present on 67% of {open_quotes}classic{close_quotes} Caucasian alleles with severe neonatal symptoms and undetectable crythrocytic GALT activity. Thus, Q188R almost defines the {open_quotes}classic{close_quotes} phenotype in Caucasian galactosemia patients. This mutation, however, is present on only 16% of the milder {open_quotes}variant{close_quotes} alleles and never in the homozygous state. Variant patients have up to 10% residual GALT activity in their red cells. Therefore, one or more as of yet uncharacterized mutations other than Q188R must be present in {open_quotes}variant{close_quotes} patients. The Q188R mutations is very rare in other ethnic and racial groups. Thus, Galactosemia is panethnic but the mutational basis of this disease differs among human populations. The frequency of Q188R is intermediate in Hispanic-American patients, probably reflecting the Spanish contribution to the gene pool in this population. We conclude that the Q188R mutation encodes the severe {open_quotes}classic{close_quotes}galactosemia phenotype in Caucasians and that other mutations produce the {open_quotes}variant{close_quotes} galactosemia phenotype.

  7. Relaxation and kinetics in scalar field theories

    International Nuclear Information System (INIS)

    Boyanovsky, D.; Lawrie, I.D.; Lee, D.

    1996-01-01

    A new approach to the dynamics of relaxation and kinetics of thermalization in a scalar field theory is presented that incorporates the relevant time scales through the resummation of hard thermal loops. An alternative derivation of the kinetic equations for the open-quote open-quote quasiparticle close-quote close-quote distribution functions is obtained that allows a clear understanding of the different open-quote open-quote coarse-graining close-quote close-quote approximations usually involved in a kinetic description. This method leads to a systematic perturbative expansion to obtain the kinetic equations including hard thermal loop resummation and to an improvement including renormalization, off-shell effects, and contributions that change chemical equilibrium on short time scales. As a by-product of these methods we establish the equivalence between the relaxation time scale in the linearized equation of motion of the quasiparticles and the thermalization time scale of the quasiparticle distribution function in the open-quote open-quote relaxation time approximation close-quote close-quote including hard thermal loop effects. Hard thermal loop resummation dramatically modifies the scattering rate for long wavelength modes as compared to the usual (semi)classical estimate. Relaxation and kinetics are studied both in the unbroken and broken symmetry phases of the theory. The broken symmetry phase also provides the setting to obtain the contribution to the kinetic equations from processes that involve decay of a heavy scalar into light scalar particles in the medium. copyright 1996 The American Physical Society

    Sammis, C.G.

    1993-01-01

    The source region of an underground explosion is commonly modeled as a nested series of shells. In the innermost open-quotes hydrodynamic regimeclose quotes pressures and temperatures are sufficiently high that the rock deforms as a fluid and may be described using a PVT equation of state. Just beyond the hydrodynamic regime, is the open-quotes non-linear regimeclose quotes in which the rock has shear strength but the deformation is nonlinear. This regime extends out to the open-quotes elastic radiusclose quotes beyond which the deformation is linear. In this paper, we develop a model for the non-linear regime in crystalline source rock where the nonlinearity is mostly due to fractures. We divide the non-linear regime into a open-quotes damage regimeclose quotes in which the stresses are sufficiently high to nucleate new fractures from preexisting ones and a open-quotes crack-slidingclose quotes regime where motion on preexisting cracks produces amplitude dependent attenuation and other non-linear effects, but no new cracks are nucleated. The boundary between these two regimes is called the open-quotes damage radius.close quotes The micromechanical damage mechanics recently developed by Ashby and Sammis (1990) is used to write an analytic expression for the damage radius in terms of the initial fracture spectrum of the source rock, and to develop an algorithm which may be used to incorporate damage mechanics into computer source models for the damage regime. Effects of water saturation and loading rate are also discussed

Namely, we present the construction of quantum logics with given sublogics (=physical subsystems), automorphism groups, centers (=open-quotes classical partsclose quotes of the systems), and state spaces. Thus, all these open-quotes parametersclose quotes are independent. Our result is rooted in the line of investigation carried out by Greechie; Kallus and Trnkova; Kalmbach; and Navara and Ptak; and considerably enriches the known algebraic methods in orthomodular posets. 19 refs., 1 fig

    In a previous paper, the author defined the open-quotes irradiation timeclose quotes as the time of irradiation in which the maximum open-quotes total background doseclose quotes becomes 2,500 RBE-cGy. In this paper, he has modified the definition a little as the time of irradiation in which the maximum open-quotes lμg/g B-10 doseclose quotes becomes 3,000 RBE-cGy, because he assumed that normal tissue contained 1μg/g B-10. Moreover, he has modified the dose criteria for BNCT as follows: The open-quotes eye doseclose quotes, open-quotes total body doseclose quotes and open-quotes except-head doseclose quotes should be less that 200, 100 and 50 RBE-cGy, respectively. He has added one more criterion for BNCT that the thermal neutron fluence at the tumor position should be over 2.5x10 12 n/cm 2 at the open-quotes irradiation timeclose quotes. The distance from the core side to the irradiation port in the open-quotes old configurationclose quotes of the Musashi reactor (TRIGA-II, 100kW) was 160 cm. He is now planning to design an eccentric core and to move the reactor core nearer to the irradiation port, distance between the core side and the irradiation port to be 140, 130 and 120cm. The other assumptions used in this paper are as follows: (1) The B-10 concentrations in tumor are 30 and/or 10μg/g. (2) The depth of the tumor is 5.0 cm to 5.5 cm from the surface. (3) The RBE values used are 1.0 for all gamma rays and 2.3 for B 10 (n,α) reaction products. (4) The RBE values for neutrons are the following three cases: the first case is using 1.6 for all neutrons; the second one is using 3.2 for non-thermal neutrons and 1.6 for thermal neutrons; the third case is using 4.8 for fast neutrons, 3.2 for faster epithermal and epithermal neutrons, and 1.6 for thermal neutrons

  11. Surface tension, hydrophobicity, and black holes: The entropic connection

    International Nuclear Information System (INIS)

    Callaway, D.J.

    1996-01-01

    The geometric entropy arising from partitioning space in a fluid open-quote open-quote field theory close-quote close-quote is shown to be linearly proportional to the area of an excluded region. The coefficient of proportionality is related to surface tension by a thermodynamic argument. Good agreement with experimental data is obtained for a number of fluids. The calculation employs a density-matrix formalism developed previously for studying the origin of black hole entropy. This approach may lead to a practical technique for the evaluation of thermodynamic quantities with important entropic components. copyright 1996 The American Physical Society

  12. Strong interactions at high energy

    International Nuclear Information System (INIS)

    Anselmino, M.

    1995-01-01

    Spin effects in strong interaction high energy processes are subtle phenomena which involve both short and long distance physics and test perturbative and non perturbative aspects of QCD. Moreover, depending on quantities like interferences between different amplitudes and relative phases, spin observables always test a theory at a fundamental quantum mechanical level; it is then no surprise that spin data are often difficult to accommodate within the existing models. A report is made on the main issues and contributions discussed in the parallel Session on the open-quote open-quote Strong interactions at high energy close-quote close-quote in this Conference. copyright 1995 American Institute of Physics

    The problem of the action of an arbitrary perturbation on a system of two identical atoms in the radiation field is analyzed. For simplicity, only two-level atoms are considered, the field is assumed to be classical, and the spontaneous transitions are ignored. The polarizations are calculated for the open-quotes two atoms + fieldclose quotes and open-quotes two atoms + field + particleclose quotes systems. A comparison of the obtained relationships allows us to clarify the character of the level distortions caused by the external perturbation in the compound system. 10 refs

    Despite their best intentions, authors often omit from publications many important technical details. These omissions can lead to contradictions in the literature and inhibit {open_quotes}researchers{close_quotes} abilities to duplicate published results. Here, the authors explore {open_quote}hidden{close_quote} parameters that are usually not reported, either because they are unknown (e.g., impurity levels) or because they are considered to be of little importance. Specifically the authors focus on the effects - and how to reduce the effects - of growth parameters in nearby layers (diffusion), impurities (oxygen), and the cooldown atmosphere (hydrogen passivation).

    Energy Technology Data Exchange (ETDEWEB)

    Hamilton, L.D.; Holtzman, S.; Meinhold, A.F.; Morris, S.C.; Rowe, M.D.

    1994-01-01

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

  1. The cleanup of releases of radioactive materials from commercial low-level radioactive waste disposal sites: Whose jurisdiction?

    International Nuclear Information System (INIS)

    Hartnett, C.

    1994-01-01

    There exists an overlap between the Comprehensive Environmental Response, Compensation and Recovery Act (open-quotes CERCLAclose quotes) and the Atomic Energy Act (open-quotes AEAclose quotes) regarding the cleanup of releases of radioactive materials from commercial low-level radioactive waste sites. The Nuclear Regulatory Commission (open-quotes NRCclose quotes) and Agreement States have jurisdiction under the AEA, and the Environmental Protection Agency (open-quotes EPAclose quotes) has jurisdiction pursuant to CERCLA. This overlapping jurisdiction has the effect of imposing CERCLA liability on parties who have complied with AEA regulations. However, CERCLA was not intended to preempt existing legislation. This is evidenced by the federally permitted release exemption, which explicitly exempts releases from CERCLA liability pursuant to an AEA license. With little guidance as to the applicability of this exemption, it is uncertain whether CERCLA's liability is broad enough to supersede the Atomic Energy Act. It is the purpose of this paper to discuss the overlapping jurisdiction for the cleanup of releases of radioactive materials from commercial low-level radioactive waste disposal sites with particular emphasis on the cleanup at the Maxey Flats, West Valley and Sheffield sites

  4. Laser-assisted collisions: The Kroll-Watson formula and bremsstrahlung theory

    International Nuclear Information System (INIS)

    Geltman, S.

    1996-01-01

    Recent measurements on CO 2 -laser-assisted electron-atom collisions have shown large inconsistencies with the Kroll-Watson formula for small-angle scattering. We have carried out a detailed study to compare the predictions of Kroll-Watson theory (for both single and multimode fields) with those of conventional perturbation theory for stimulated free-free transitions. It is found that for E 0 /2ω 2 <1, where perturbation theory is valid, there are large differences with the Kroll-Watson theory. Comparisons of experimental variations with respect to scattering angle and electron energy show much better agreement with perturbation theory than with Kroll-Watson theory. A study of the angular variations in perturbation theory shows that use of the open-quote open-quote outgoing close-quote close-quote wave final state gives much better agreement with experiment than does the open-quote open-quote ingoing close-quote close-quote wave final state, which is different from the choice made in early bremsstrahlung theory. copyright 1996 The American Physical Society

  8. Expansion, thermalization, and entropy production in high-energy nuclear collisions

    International Nuclear Information System (INIS)

    Heiselberg, H.; Wang, X.

    1996-01-01

    The thermalization process is studied in an expanding parton gas using the Boltzmann equation with two types of collision terms. In the relaxation time approximation we determine the criteria under which a time-dependent relaxation time leads to thermalization of the partons. We calculate the entropy production due to collisions for the general time-dependent relaxation time. In a perturbative QCD approach on the other hand, we can, given the initial conditions, estimate the effective relaxation time due to elastic collisions; this will be an upper limit only since radiative processes will also contribute to thermalization. We find that the parton gas does thermalize eventually but only after having undergone a phase of free streaming and gradual equilibration where considerable entropy is produced (open-quote open-quote after burning close-quote close-quote). The final entropy and thus particle density depends on the collision time as well as the initial conditions (a open-quote open-quote memory effect close-quote close-quote). Results for entropy production are presented based upon various model estimates of early parton production. copyright 1996 The American Physical Society

  9. Derivative expansions of renormaliztion group effective potentials for φ4 field theories

    International Nuclear Information System (INIS)

    Shepard, J.R.; McNeil, J.A.

    1995-01-01

    We approximate an exact Renormalization Group (RG) equation for the flow of the effective action of φ 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 η (0.046). We also find the critical exponents ν (0.666) and ω (0.735). These latter two are in much improved agreement with open-quote world's bestclose quotes values com- pared to those obtained at LO (where no prediction for η 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 cutoffclose quotes formulations do not arise with our RG equations

  11. Deformed Heisenberg algebra, fractional spin fields, and supersymmetry without fermions

    Plyushchay, M.S.

    1996-01-01

    Within a group-theoretical approach to the description of (2+1)-dimensional anyons, the minimal covariant set of linear differential equations is constructed for the fractional spin fields with the help of the deformed Heisenberg algebra (DHA), [a - ,a + ]=1+νK, involving the Klein operator K, {K,a ± }=0, K 2 =1. The connection of the minimal set of equations with the earlier proposed open-quote open-quote universal close-quote close-quote vector set of anyon equations is established. On the basis of this algebra, a bosonization of supersymmetric quantum mechanics is carried out. The construction comprises the cases of exact and spontaneously broken N=2 supersymmetry allowing us to realize a Bose endash Fermi transformation and spin-1/2 representation of SU(2) group in terms of one bosonic oscillator. The construction admits an extension to the case of OSp(2 parallel 2) supersymmetry, and, as a consequence, both applications of the DHA turn out to be related. The possibility of open-quote open-quote superimposing close-quote close-quote the two applications of the DHA for constructing a supersymmetric (2+1)-dimensional anyon system is discussed. As a consequential result we point out that the osp(2 parallel 2) superalgebra is realizable as an operator algebra for a quantum mechanical 2-body (nonsupersymmetric) Calogero model.

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

    International Nuclear Information System (INIS)

    Wang, Y.

    1996-01-01

    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 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% for l approx-lt 50, less than 10% for l approx-lt 120, and less than 20% for l≤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 1996 The American Physical Society

    1996-01-01

    A group-theoretic quantization method is applied to the open-quote open-quote complete symmetry group close-quote close-quote describing the motion of a point charge in a constant magnetic field. Within the regular ray representation, the Schroedinger operator is obtained as the Casimir operator of the extended Lie algebra. Configuration ray representations of the complete group cast the Schroedinger operator into the familiar space-time differential operator. Next, open-quote open-quote group quantization close-quote close-quote yields the superselection rules, which produce irreducible configuration ray representations. In this way, the Schroedinger operator becomes diagonalized, together with the angular momentum. Finally, the evaluation of an invariant integral, over the group manifold, gives rise to the Feynman propagation kernel left-angle t',x'|t,x right-angle of the system. Everything stems from the assumed symmetry group. Neither canonical quantization nor the path-integral method is used in the present analysis. copyright 1996 The American Physical Society

  9. A quantitative method for measuring the quality of history matches

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

  10. Dynamic perception: Some theorems about the possibility of parallel pattern recognition with an application to high energy physics

    Perrone, A.; Basti, G.

    1994-01-01

    In the context of M. Minsky's and S. Papert's theorems on the impossibility of evaluating simple linear predicates by parallel architectures the authors want to show how these limitations can be avoided by introducing a generalized input-dependent preprocessing technique that does not suppose any a-priori knowledge of input like in classical input filtering procedures. This technique can be formalized in a very general way and can be also deduced by metamathematical arguments. A further development of the same technique can be applied at level of learning procedure to introduce in such a way the complete notion of open-quotes dynamic perceptronclose quotes. From the experimental standpoint, they show two applications of the open-quotes dynamic perceptronclose quotes in particle track recognition in high-energy accelerators. Firstly, they show the amazing improvement of performances that can be obtained in a perceptron architecture with classical learning by adding their open-quotes dynamicclose quotes pre-processing technique, already introduced last year in another paper presented at this Conference. Secondly, they show the results of this technique extended also at the level of learning procedure always applied to the problem of particle track recognition.

  14. Axiomatic derivation of Feynman rules and related topics

    International Nuclear Information System (INIS)

    Dorfmeister, G.K.

    1992-01-01

    Previous results in axiomatic field theory by Steinmann and Epstein-Glaser establish the existence of the retarded and time ordered Green's functions in every order of perturbation. To connect these Green's functions with the ones calculated in canonical field theories via the Feynman rules, one has to consistently build them not just for every order of perturbation but for each specific graph. (open-quotes Consisentlyclose quotes means here that the Green functions associated with two open-quotes smallclose quotes graphs build up to the Green's functions of the open-quotes bigclose quotes graph formed by connecting the two open-quotes smallclose quotes ones). This paper shows that this can indeed be done; that in this sense the Feynman rules of perturbative Lagrangian field theory can be derived from the abstract, but physically very basic, principles of axiomatic field theory. All results hold only for massive field theories. The LSZ formalism, to the best knowledge of the author, has so far not been modified to admit mass zero fields. To make the representation simpler and more transparent, the author restricts the discussion to a single component, scalar Φ 4 interaction which is a part of the Standard Model of Particle Physics. Motivated by its role in particle physics, the author complements the perturbative study of Φ 4 -theory by reviewing the status of non-perturbative solutions to the theory in the final chapter

(2) Structural changes are occurring in both the long-term uranium market and the uranium production sector. (3) Brokers, traders and other intermediaries are becoming increasingly active in the marketplace. (4) The NUEXCO Exchange Value and other spot market price indicators are at all-time lows. It is my contention, however, that the current state of affairs in the uranium market is the logical and inevitable economic result of past excesses, primarily the buildup, during the late 1970s and early 1980s, of huge inventories. Today there is still substantial excess inventory in the system, and, until this inventory is absorbed, either prospectively or in fact, uranium prices will remain under pressure

    We employ an algebraic approach for unifying perturbative and nonperturbative superstring states on an equal footing, in the form of U-duality multiplets, at all excited string levels. In compactified type-IIA supertring theory we present evidence that the multiplet is labeled by two spaces, open-quote open-quote index close-quote close-quote space and open-quote open-quote base close-quote close-quote space, on which U acts without mixing them. Both spaces are nonperturbative extensions of similar spaces that label perturbative T-duality multiplets. Base space consists of all the central charges of the 11D SUSY algebra, while index space corresponds to representations of the maximal compact subgroup K improper-subset U. This structure predicts the quantum numbers of the nonperturbative states. We also discuss whether and how U multiplets may coexist with 11-dimensional multiplets that are associated with an additional nonperturbative 11D structure that seems to be lurking behind in the underlying theory. copyright 1996 The American Physical Society

    We study a quantum analogue of the iterative perturbation theory by Kolmogorov used in the proof of the Kolmogorov endash Arnold endash Moser (KAM) theorem. The method is based on sequent canonical transformations with a open-quote open-quote running close-quote close-quote coupling constant λ, λ 2 , λ 4 , etc. The proposed scheme, as its classical predecessor, is open-quote open-quote superconvergent close-quote close-quote in the sense that after the nth step, a theory is solved to the accuracy of order λ 2n-1 . It is shown that the Kolmogorov technique corresponds to an infinite resummation of the usual perturbative series. The corresponding expansion is convergent for the quantum anharmonic oscillator due to the fact that it turns out to be identical to the Pade series. The method is easily generalizable to many-dimensional cases. The Kolmogorov technique is further applied to a non-perturbative treatment of Yang endash Mills quantum mechanics. A controllable expansion for the wave function near the origin is constructed. For large fields, we build an asymptotic adiabatic expansion in inverse powers of the field. This asymptotic solution contains arbitrary constants which are not fixed by the boundary conditions at infinity. To find them, we approximately match the two expansions in an intermediate region. We also discuss some analogies between this problem and the method of QCD sum rules. Copyright copyright 1995 Academic Press, Inc

  13. Testing quantum mechanics using third-order correlations

    International Nuclear Information System (INIS)

    Kinsler, P.

    1996-01-01

    Semiclassical theories similar to stochastic electrodynamics are widely used in optics. The distinguishing feature of such theories is that the quantum uncertainty is represented by random statistical fluctuations. They can successfully predict some quantum-mechanical phenomena; for example, the squeezing of the quantum uncertainty in the parametric oscillator. However, since such theories are not equivalent to quantum mechanics, they will not always be useful. Complex number representations can be used to exactly model the quantum uncertainty, but care has to be taken that approximations do not reduce the description to a hidden variable one. This paper helps show the limitations of open-quote open-quote semiclassical theories,close-quote close-quote and helps show where a true quantum-mechanical treatment needs to be used. Third-order correlations are a test that provides a clear distinction between quantum and hidden variable theories in a way analogous to that provided by the open-quote open-quote all or nothing close-quote close-quote Greenberger-Horne-Zeilinger test of local hidden variable theories. copyright 1996 The American Physical Society

    While admitting sharply contrasting views exist, James M. Lents of the South Coast Air Quality Management District in southern California sees emissions trading open-quotes as a lifesaver for our troubled planet.close quotes He explains: open-quotes If political support for the environment is to be maintained, we must seek the most economical and flexible means of pursuing cleanup.

The air quality management district he heads plans to use market incentives, including emissions trading, to reduce air pollution in the notoriously dirty southern California area. When the system goes into operation in 1994, he estimates it will save southern California businesses more than $400 million a year in compliance costs, while also making major improvements in the region's air quality. If the idea works there, why won't it work elsewhere, even on a global scale, Lents asks? He believes it will. But open-quotes the ultimate success of emissions-trading programs, whether regional, national, or international in scope, lies in the proof that they're actually achieving reductions in harmful emissions,close quotes he emphasizes. open-quotes These reductions must be real and verifiable to satisfy the Clean Air Act and a skeptical public.close quotes

    The last Construction Permit to be issued by the U.S. Nuclear Regulatory Commission (NRC) for a U.S. light water reactor (LWR) was granted in the late 1970s. In 1989 the NRC issued 10 CFR Part 52 which is intended to serve as a framework for the licensing of future reactor designs. The NRC is currently reviewing four different future on {open_quotes}next-generation{close_quotes} reactor designs. Two of these designs are classified as evolutionary designs (modified versions of current generation LWRs) and two are advanced designs (reactors incorporating simplified designs and passive means for accident mitigation). These {open_quotes}next-generation{close_quotes} reactor designs incorporate many innovative design features which are intended to maintain personnel doses ALARA and ensure that the annual average collective dose at these reactors does not exceed 100 person-rems (1 person-sievert) per year.

In this article, this HPS committee made the statement that they were deeply concerned by the trend for agencies to incorporate the ALARA concept as a regulatory requirements, without providing specific guidance as to what it means and how to implement it consistently. The HPS position paper was in response to the DOE notice on proposed rulemaking for Title 10 Code of Federal Regulations Part 834, {open_quotes}Radiation Protection of the Public and the Environment{close_quotes} (10 CFR 834). In the notice of proposed rulemaking for 10 CFR 834, the Department of Energy (DOE) defined ALARA as follows: {open_quotes}As used in this part, ALARA is not a dose limit, but rather a process which has the objective of attaining doses as far below the applicable limit of this part as is reasonably achievable{close_quotes} (10 CFR 834.2, p. 16283 of the Federal Register).

    1996-01-01

    Self-organization phenomena are spontaneous processes. Their behavior should be governed by the second law of thermodynamics. The dissipative structure theory of the Prigogine school of thermodynamics claims that open-quotes order out of chaosclose quotes through open-quotes self-organizationclose quotes and challenges the validity of the second law of thermodynamics. Unfortunately this theory is questionable. Therefore we have to reconsider the related fundamental theoretical problems. Informational entropy (S) and information (I) are related by S = S max - I, where S max is the maximum informational entropy. This conforms with the broadly accepted definition that entropy is the information loss. As informational entropy concept has been proved to be useful, it will be convenient to define an informational temperature, T I . This can be related to energy E and the informational entropy S. Information registration is a process of ΔI > 0, or ΔS 0). Therefore, T I is negative, and has the opposite sign of the conventional thermodynamic temperature, T. This concept is useful for clarifying the concepts of open-quotes orderclose quotes and open-quotes disorderclose quotes of static structures and characterizing many typical information loss processes of self-organization

Our biggest problem is the general public has a negative emotional reaction to the term open-quotes nuclear.close quotes I conduct tours at Wolf Creek generating station near Burlington, Kansas, in America's heartland.

They want to know how much radiation exposure they are receiving and tell me about friends who were supposed to accompany them on their tour but who were so concerned about their safety that they opted to stay at home. Once these people have completed their tour, their minds are eased. It is at that point that I ask them to do a simple word association test on themselves.

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

    One of the major management programs used for commercial, laboratory, and defense nuclear facilities is configuration management. The safe and efficient operation of a nuclear facility requires constant vigilance in maintaining the facility's design basis with its as-built condition. Numerous events have occurred that can be attributed to (either directly or indirectly) the extent to which configuration management principles have been applied. The nuclear industry, as a whole, has been addressing this management philosophy with efforts taken on by its constituent professional organizations.

    2017-10-01

    We develop a new approach to reflect the behavior of algorithmic traders. Specifically, we provide an analytical and tractable way to infer patterns of quote volatility and price momentum consistent with different types of strategies employed by algorithmic traders, and we propose two ratios to quantify these patterns. Quote volatility ratio is based on the rate of oscillation of the best ask and best bid quotes over an extremely short period of time; whereas price momentum ratio is based on identifying patterns of rapid upward or downward movement in prices. The two ratios are evaluated across several asset classes. We further run a two-stage Artificial Neural Network experiment on the quote volatility ratio; the first stage is used to detect the quote volatility patterns resulting from algorithmic activity, while the second is used to validate the quality of signal detection provided by our measure.

    Nimz, G.J.

    1995-01-01

    A variety of physical processes affect solute concentrations within catchment waters. The isotopic compositions of the solutes can indicate which processes have determined the observed concentrations. These processes together constitute the physical history of the water, which is one of the primary concerns in hydrology. Many groundwater solutes are derived as a result of interaction between the water and the rock and/or soil within the system. These are termed open-quotes lithogenicclose quotes solutes. The isotopic compositions of these solutes provide information regarding rock-water interactions. Many other solutes have their isotopic compositions determined both internally and externally to the catchment system. Important members of this group include solutes that have isotopic compositions produced by atomic particle interactions with other nuclides. The source of the atomic particles can be cosmic radiation (producing open-quotes cosmogenicclose quotes nuclides in the atmosphere and land surface), anthropogenic nuclear reactions (producing open-quotes thermonuclearclose quotes nuclides), or radioactive and fission decay of naturally-occurring elements, such as U and Th (producing open-quotes in-situclose quotes lithogenic nuclides in the deep subsurface). Current language usage often combines all of the atomic particle-produced nuclides under the heading open-quotes cosmogenic nuclidesclose quotes, and for simplicity we will often follow that usage, although always clearly indicating which variety is being discussed.

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

    Task 8 is responsible for assessing the hydrocarbon potential of the Yucca Mountain vicinity. Our main focus is source rock stratigraphy in the Nevada Test Site (NTS) area in southern Nevada. In order to reconstruct the Paleozoic stratigraphy, we are also studying the geometry and kinematics of deformation at NTS. A thorough understanding of the structure will also be essential to predicting the nature of the Late Paleozoic rocks under Yucca Mountain. Our stratigraphic studies continue to support the interpretation that rocks mapped as the open-quotes Eleana Formationclose quotes are in fact parts of two different Mississippian units. We are now provisionally limiting the name open-quotes Eleana Formationclose quotes to the rocks that make up the Eleana Range - i.e., the rocks that we have been calling open-quotes western Eleanaclose quotes. The mudstone section (which we have until now called open-quotes eastern Eleanaclose quotes) we are provisionally calling the open-quotes Chainman Shaleclose quotes, in keeping with regional lithostratigraphic nomenclature. We continue to work out the internal stratigraphies and basin histories of both units; XRD (r-ray diffraction) determinations of clay mineralogy are an addition to our understanding of the Chainman. The basin histories place important constraints on regional paleogeographic and tectonic reconstructions. This year we have hired a consulting petroleum geologist for two jobs: (1) to review drillhole data from southern Nevada on file at NBMG and make recommendations about more detailed study of any interesting drillholes; and (2) to log the UE17e core (in the Chainman) and evaluate source rock potential. The results of these studies have been incorporated into this report, and the consultant's reports

    1994-01-01

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

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

    Perplexing environmental questions, such as acid rain and global warming, cry out for policy solutions based upon solid scientific evidence. Scientists and politicians agree on this but have trouble finding an effective way to do it. Milton Russell of the University of Tennessee and Oak Ridge National Laboratory describes a major, but only partially successful, effort that he believes contains valuable lessons for scientists and policy makers in the future. It is the National Acid Precipitation Assessment Program (NAPAP), launched in 1980 to generate the latest scientific evidence to guide national debate on clean-air legislation. The program open-quotes created an unprecedented body of scientific research on an environmental issue of the first order,close quotes Russell says. Yet, he admits, its influence was virtually nil on the legislation that ultimately emerged on the subject. Russell blames this lack of influence on NAPAP's failure to provide adequate assessment of its research findings, its failure to communicate the results on a timely and effective basis, and on open-quotes political forces that sought legislation rather than a full explication of issues.close quotes Out of the experience, Russell finds lessons for the future: open-quotes First, if the scientific finding are to have an impact on policy, assessment must become a priority as important as scientific research. Second, for projects designed to help decision makers, scientific research must be considered a resource, not an end product. Third, timely, lucid communication must be an essential element of the project, not a marginal activity.close quotes NAPAP, Russell concludes, open-quotes proved a long-term scientific success and a short-term policy disappointment.close quotes Then he warns, open-quotes Future science programs ignore the NAPAP experience at their own risk.close quotes

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

    Misinformation and public misunderstanding have given emissions trading a bad reputation in the public marketplace, says William F. Malec, executive vice president of the Tennessee Valley Authority (TVA), in Knoxville, Tennessee. Media coverage of a May 1992 emissions-allowance trade between TVA and Wisconsin Power and Light open-quotes focused on the agreement's pollution-trading aspects, not its overall potential economic and environmental benefits,close quotes Malec says. Such negative portrayal of TVA's transaction sparked severe public criticism and charges that emissions trading gives utilities the right to pollute. open-quotes The fact is that TVA sought the emissions-trading agreement as a means to reduce overall emissions in the most cost-effective way,close quotes Malec explains. Emissions trading allows a company with emission levels lower than clean-air standards to earn open-quotes credits.close quotes These credits then may be purchased by a company with emission levels that exceed federal standards. Under this arrangement, the environment is protected and companies that buy credits save money because they do not have to purchase expensive emissions-control devices or reduce their production levels. Malec says TVA decided to enter into the emissions-allowance market, not only to cut costs, but also to publicize the existence and benefits of emissions trading. However, TVA's experience proves that open-quotes people will not accept what they do not understand,close quotes concludes Malec, open-quotes especially when complex environmental issues are involved.close quotes

  11. Production and measurement of minor actinides in the commercial fuel cycle

    Stanbro, W.D.

    1997-03-01

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

    1995-01-01

    We clarify the relationship and difference between theories of the optical-model potential which had previously been developed in the framework of Feshbach's projection operator approach to nuclear reactions and of Green's function theory, respectively. For definiteness, we consider the nucleon-nucleus system but all results can readily be adapted to the atomic case. The effects of antisymmetrization are properly taken into account. It is shown that one can develop along closely parallel lines the theories of open-quotes holeclose quotes and open-quotes particleclose quotes mean fields. The open-quotes holeclose quotes one-body Hamiltonians describe the single-particle properties of the system formed when one nucleon is taken away from the target ground state, for instance in knockout of pickup processes. The particle one-body Hamiltonians are associated with the system formed when one nucleon is elastically scattered from the ground state, or is added to it by means of stripping reactions. An infinite number of particle, as well as of hole, Hamiltonians are constructed which all yield exactly the same single-particle wave functions. Many open-quotes equivalentclose quotes one-body Hamiltonians can coexist because these operators have a complicated structure: they are nonlocal, complex, and energy-dependent. They do not have the same analytic properties in the complex energy plane. Their real and imaginary parts fulfill dispersion relations which may be different. It is shown that hole and particle Hamiltonians can also be constructed by decomposing any vector of the Hilbert space into two parts which are not orthogonal to one another, in contrast to Feshbach's original theory; one interest of this procedure is that the construction and properties of the corresponding hole Hamiltonian can be justified in a mathematically rigorous way. We exhibit the relationship between the hole and particle Hamiltonians and the open-quotes mass operator.close quotes

  14. Smile (System/Machine-Independent Local Environment)

    Energy Technology Data Exchange (ETDEWEB)

    Fletcher, J.G.

    1988-04-01

    This document defines the characteristics of Smile, a System/machine-independent local environment. This environment consists primarily of a number of primitives (types, macros, procedure calls, and variables) that a program may use; these primitives provide facilities, such as memory allocation, timing, tasking and synchronization beyond those typically provided by a programming language. The intent is that a program will be portable from system to system and from machine to machine if it relies only on the portable aspects of its programming language and on the Smile primitives. For this to be so, Smile itself must be implemented on each system and machine, most likely using non-portable constructions; that is, while the environment provided by Smile is intended to be portable, the implementation of Smile is not necessarily so. In order to make the implementation of Smile as easy as possible and thereby expedite the porting of programs to a new system or a new machine, Smile has been defined to provide a minimal portable environment; that is, simple primitives are defined, out of which more complex facilities may be constructed using portable procedures. The implementation of Smile can be as any of the following: the underlying software environment for the operating system of an otherwise {open_quotes}bare{close_quotes} machine, a {open_quotes}guest{close_quotes} system environment built upon a preexisting operating system, an environment within a {open_quotes}user{close_quotes} process run by an operating system, or a single environment for an entire machine, encompassing both system and {open_quotes}user{close_quotes} processes. In the first three of these cases the tasks provided by Smile are {open_quotes}lightweight processes{close_quotes} multiplexed within preexisting processes or the system, while in the last case they also include the system processes themselves.

  15. Lithogenic and cosmogenic tracers in catchment hydrology

    1995-01-01

    A variety of physical processes affect solute concentrations within catchment waters. The isotopic compositions of the solutes can indicate which processes have determined the observed concentrations. These processes together constitute the physical history of the water, which is one of the primary concerns in hydrology. Many groundwater solutes are derived as a result of interaction between the water and the rock and/or soil within the system. These are termed {open_quotes}lithogenic{close_quotes} solutes. The isotopic compositions of these solutes provide information regarding rock-water interactions. Many other solutes have their isotopic compositions determined both internally and externally to the catchment system. Important members of this group include solutes that have isotopic compositions produced by atomic particle interactions with other nuclides. The source of the atomic particles can be cosmic radiation (producing {open_quotes}cosmogenic{close_quotes} nuclides in the atmosphere and land surface), anthropogenic nuclear reactions (producing {open_quotes}thermonuclear{close_quotes} nuclides), or radioactive and fission decay of naturally-occurring elements, such as U and Th (producing {open_quotes}in-situ{close_quotes} lithogenic nuclides in the deep subsurface). Current language usage often combines all of the atomic particle-produced nuclides under the heading {open_quotes}cosmogenic nuclides{close_quotes}, and for simplicity we will often follow that usage, although always clearly indicating which variety is being discussed. This paper addresses the processes that affect the lithogenic and cosmogenic solute compositions in groundwater, and how these compositions can therefore be used in integrative ways to understand the physical history of groundwater within a catchment system.

    When CERCLA was originally passed in 1980, the petroleum industry lobbied successfully to exclude the term open-quotes petroleumclose quotes from the definition of a CERCLA section 101 (14) hazardous substance. Under CERCLA section 101 (33), petroleum is also excluded from the definition of a open-quotes pollutant or contaminant.close quotes Exclusion from the designation as a defined hazardous substance has provided a defense to liability under CERCLA section 107 when the release of petroleum occurs. The scope of the petroleum exclusion under CERCLA has been a critical and recurring issue arising in the context of Superfund response activities. Specifically, oil that is contaminated by hazardous substances during the refining process is considered open-quotes petroleumclose quotes under CERCLA and thus excluded from CERCLA response authority and liability unless specifically listed under RCRA or some other statute. The U.S. EPAs position is that contaminants present in used oil, or any other petroleum substance, do not fall within the petroleum exclusion. open-quotes Contaminants,close quotes as discussed here, are substances not normally found in refined petroleum fractions or present at levels which exceed those normally found in such fractions. If these contaminants are CERCLA hazardous substances, they are subject to CERCLA response authority and liability. This paper discusses the parameters of the CERCLA open-quotes Petroleum Exclusion.close quotes It briefly examines selected state laws, RCRA, the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA) for treatment of petroleum and petroleum products.

    1996-01-01

    Currently favored extensions of the standard model typically contain open-quote open-quote flaton fields close-quote close-quote defined as fields with large vacuum expectation values (VEV close-quote s) and almost flat potentials. If a flaton field is trapped at the origin in the early Universe, one expects open-quote open-quote thermal inflation close-quote close-quote to take place before it rolls away to the true vacuum, because the finite-temperature correction to the potential will hold it at the origin until the temperature falls below 1 TeV or so. In the first part of the paper, that expectation is confirmed by an estimate of the finite-temperature corrections and of the tunneling rate to the true vacuum, paying careful attention to the validity of the approximations that are used. The second part of the paper considers topological defects which may be produced at the end of an era of thermal inflation. If the flaton fields associated with the era are grand unified theory (GUT) Higgs fields, then its end corresponds to the GUT phase transition. In that case monopoles (as well as GUT Higgs particles) will have to be diluted by a second era of thermal inflation. Such an era will not affect the cosmology of GUT strings, for which the crucial parameter is the string mass per unit length. Because of the flat Higgs potential, the GUT symmetry-breaking scale required for the strings to be a candidate for the origin of large scale structure and the CMB anisotropy is about three times bigger than usual, but given the uncertainties it is still compatible with the one required by the unification of the standard model gauge couplings. The cosmology of textures and of global monopoles is unaffected by the flatness of the potential. copyright 1996 The American Physical Society

  18. The effect of disorder and fluctuations on the magnetotransport of a double-exchange ferromagnet (abstract)

    Byers, J.M.

    1996-01-01

    The discovery of colossal magnetoresistance (CMR) in the doped perovskite manganites has reawakened interest in the double-exchange mechanism proposed to Zener. To account for the close relation between ferromagnetism and metallic transport in lanthanum manganites doped with divalent cation (Ca, Sr, Ba) Zener claimed that an electron could delocalize on lattice of spins and still conform to Hund close-quote s Rule if a ferromagnetic coupling between spins were mediated by that same electron. Thus, the onset of metallic behavior (delocalization) is intimately linked to ferromagnetic ordering of the spin lattice. Clearly, the double-exchange mechanism provides some necessary physics but is not sufficient in explaining the key mystery of the CMR materials: What causes the large peak in the resistivity vs. temperature and why is it removed by an applied magnetic field. The effect of disorder and fluctuations on the double-exchange mechanism may provide the answers. Several sources of disorder in these materials act to form a mobility edge via Anderson localization: intrinsic divalent/trivalent cation disorder, off-diagonal disorder caused by the spin lattice and oxygen vacancy disorder. A mean-field calculation reveals that below the Curie temperature those carriers aligned opposite to the magnetization experience a narrowing band as the temperature is reduced. Fermi glass behavior is induced in this minority carrier band by the Fermi level falling below the mobility edge. However, the mean-field result does not contain a peak in resistivity since the majority carrier band does not behave as a Fermi glass and effectively open-quote open-quote shorts out close-quote close-quote the more resistive minority conduction channel. The formation of the resistivity peak requires the inclusion of ferromagnetic fluctuations above the Curie temperature that tend to open-quote open-quote mix close-quote close-quote the two conduction channels.

    An extensive risk assessment of BETX emissions from the Valdez Marine Terminal has been completed. The exposure assessment included four fixed, continuous monitoring sites as well as supplementary ambient monitoring during two short-term intensive field studies using the EPA TEAM approach and tracer techniques. One of the reasons for such extensive monitoring was the concern that open-quotes Guidelineclose quotes models would not work well in Valdez's fjord. Post-measurement analysis has been used to determine the efficacy and accuracy of the open-quotes Guidelineclose quotes models and physical modeling techniques as applied to transport and dispersion in the fjord. Model predictions have been compared to an extensive set of monitored concentrations. As anticipated, the models exhibit poor skill in matching observed concentrations both in space and time

    1993-12-31

    Continued research and development of environmentally-acceptable and cost-effective end uses for wood ash is having a significant affect on the ability to use wood and wood waste for fuel. This is particularly true for ash resulting from treated wood combustion. Concerns about the contents of ash from wood containing paint, stain, preservatives, or other chemicals is one of the largest regulatory barriers to its use as fuel. The purpose of this paper is to: (1) Identify the physical and chemical characteristics of ashes produced from the combustion of untreated and treated wood; (2) Explain the types of {open_quotes}clean, untreated{close_quotes} and {open_quotes}treated{close_quotes} wood that are likely to produce ash that can beneficially used; (3) Describe existing and potential products and end uses for untreated and treated wood ash.

    Rajan, J.R.

    1994-05-01

    Concerns regarding the reliability of large-bore, medium-speed diesel generators manufactured by Transamerica Delaval, Inc. (TDI) for application at domestic nuclear plants were first prompted by a crankshaft failure at Shoreham Nuclear Power Station in August 1983. A number of diesel generator components were identified which had potential deficiencies from a manufacturing and operational standpoint. In response to these problems, 11 (now 8) U.S. nuclear utility owners formed a TDI Diesel Generator Owners Group (Owners Group) to address operational and regulatory issues relative to diesel generator sets used for standby emergency power. The Owners' Group performed extensive design reviews of all key engine components and developed recommendations to be implemented by the individual owners concerning needed component replacements and modifications, component inspections to validate the open-quotes as-manufacturedclose quotes and open-quotes as-assembledclose quotes quality of key engine components, engine testing, and an enhanced maintenance and surveillance program

    1996-12-01

    Periodic inspections of pump and valve inservice testing (IST) programs in United States commercial nuclear power plants are performed by Nuclear Regulatory Commission (NRC) Regional Inspectors to verify licensee regulatory compliance and licensee commitments. IST inspections are conducted using NRC Inspection Procedure 73756, {open_quotes}Inservice Testing of Pumps and Valves{close_quotes} (IP 73756), which was updated on July 27, 1995. A large number of IST inspections have also been conducted using Temporary Instruction 2515/114, {open_quotes}Inspection Requirements for Generic Letter 89-04, Acceptable Inservice Testing Programs{close_quotes} (TI-2515/114), which was issued January 15, 1992. A majority of U.S. commercial nuclear power plants have had an IST inspection to either IP 73756 or TI 2515/114. This paper is intended to summarize the significant and recurring findings from a number of these inspections since January of 1990.

    The corrosive environment around the containers in a Canadian nuclear fuel waste disposal vault will change over time from open-quotes warm and oxidizingclose quotes to open-quotes cool and anoxic.close quotes As the conditions change, so too will the corrosion behaviour of the containers. For copper containers, uniform corrosion and, possibly, pitting will occur during the initial aggressive phase, to be replaced by slow uniform corrosion during the long-term anoxic period. The corrosion behaviour of copper has been studied over a range of conditions representing all phases in the evolution of the vault environment. The results of these studies are summarized and used to illustrate how a model can be developed to predict the corrosion behaviour and container lifetimes over long periods of time. Lifetimes in excess of 10 6 a are predicted for 25-mm-thick copper containers under Canadian disposal conditions

    Microbes are playing increasingly important roles in commercial mining operations, where they are being used in the open-quotes bioleachingclose quotes of copper, uranium, and gold ores. Direct leaching is when microbial metabolism changes the redox state of the metal being harvested, rendering it more soluble. Indirect leaching includes redox chemistry of other metal cations that are then coupled in chemical oxidation or reduction of the harvested metal ion and microbial attack upon and solubilization of the mineral matrix in which the metal is physically embedded. In addition, bacterial cells are used to detoxify the waste cyanide solution from gold-mining operations and as open-quotes absorbantsclose quotes of the mineral cations. Bacterial cells may replace activated carbon or alternative biomass. With an increasing understanding of microbial physiology, biochemistry and molecular genetics, rational approaches to improving these microbial activities become possible. 40 refs., 3 figs

    Isotopes that spontaneously emit alpha (α) or beta (β) particles, or gamma rays (γ), are said to be radioactive. The emission process, called open-quotes decay,close quotes is precisely what makes radioactive isotopes, known as open-quotes radioisotopes,close quotes useful in a variety of applications, including nuclear medicine, commercial sterilization, manufacturing, geophysics, agriculture, and research programs in these and various other fields. Until 1960, radioisotope production was limited to government-owned nuclear reactors and particle accelerators in universities and government laboratories, primarily because the enormous cost of building these facilities could only be supported by government budgets. During this time, a few private companies managed to secure commercial rights to exploit the production capabilities of these facilities. Today, these companies and a few government agencies still provide the basis of global commercial radioisotope supply

  10. Recommendations for the application of fracture toughness data for structural integrity assessments

    International Nuclear Information System (INIS)

    Wallin, K.

    1993-01-01

    Large scale testing for the purpose of fracture mechanics verification is essentially directed towards the validation of the transferability of material data obtained with small specimens. Unfortunately the results are sometimes controversial, insinuating that the transferability is imprecise at the very least. However, it seems that in many cases the controversy is due to an improper application of the small specimen data. Present testing standards do not give any recommendations for the correct application of fracture toughness data and yet this is a crucial point for successful structural integrity assessment and fracture mechanics verification. In this presentation the topic concerning recommendations is addressed, focusing on the application of brittle (cleavage type) fracture data. Simple guidelines for obtaining optimum open-quotes best-close quotes and open-quotes safe-close quotes estimates of the behavior of the actual structure based on small specimen data are presented. 51 refs., 16 figs., 1 tab

    The resistance of seven cultures of eutrophic and oligotrophic bacteria to gamma radiation (at doses up to 360 Gy) was investigated. The bacteria under study were divided into three groups according to their survival ability after irradiation. Methylobacterium organophilum and open-quotes Pedodermatophilus halotoleransclose quotes (LD 50 = 270 Gy) were highly tolerant. By their tolerance, these organisms approached Deinococcus radiodurans. Aquatic ring-shaped (toroidal) bacteria Flectobacillus major and open-quotes Arcocella aquaticaclose quotes (LD 5 = 173 and 210 Gy, respectively) were moderately tolerant. Eutrophic Pseudomonas fluorescens and Escherichia coli (LD 50 = 43 and 38 Gy, respectively) were the most sensitive. X-ray microanalysis showed that in tolerant bacteria the intracellular content of potassium increased and the content of calcium decreased after irradiation. No changes in the element composition of the eutrophic bacterium E. coli were detected. Possible mechanisms of the resistance of oligotrophic bacteria to gamma radiation are discussed

    It is well known that at long wavelengths λ an s-wave scatterer can have a scattering cross section σ on the order of λ 2 , much larger than its physical size, as measured by the range of its potential. Very interesting phenomena can arise when two or more identical scatterers are placed close together, well within one wavelength. We show that, for a pair of identical scatterers, an extremely narrow p-wave open-quote open-quote proximity close-quote close-quote resonance develops from a broader s-wave resonance of the individual scatterers. A new s-wave resonance of the pair also appears. The relation of these proximity resonances (so called because they appear when the scatterers are close together) to the Thomas and Efimov effects is discussed. copyright 1996 The American Physical Society

    1995-01-01

    The National Research Council recently completed a three-year study entitled open-quotes Alternatives for Groundwater Cleanupclose quotes. One of the conclusions of this study indicated that for sites with a complex geologic and hydrologic set up, existing technologies may not be able to restore contaminated aquifers to health-based standards. Therefore, the most logical approach in these cases, perhaps, could be to adopt the open-quotes non-attainment zoneclose quotes policy. The essence of this policy is to first contain the plume and stop any further migration of contaminated groundwater, and then to remove the source of contamination. This paper briefly discusses some of the problems encountered with this approach for a contaminated area at the US Department of Energy's Lawrence Berkely National Laboratory

    Lucas, W.

    1994-12-31

    Many solution notions in the multiperson cooperative games (in characteristic function form) make use of linear programming (LP). The popular concept of the {open_quotes}core{close_quotes} of a coalitional game is a special type of LP. It can be introduced in a very simple and quite exciting manner by means of a group experiment. A total of fifty dollars will be given to three randomly selected attendees who will take part in an experiment during this talk, presuming they behave in a Pareto optimal manner. Furthermore, the dual of the particular LP for the core gives rise to the idea of {open_quotes}balanced sets{close_quotes} which is an interesting combinatorial structure in its own right.
