    The European Union is funding the ORAMED Contract (Optimization of RAdiation protection for MEDical staff) project that aims at developing methodologies for better assessing and reducing exposures to medical staff for procedures resulting in potentially large doses or complex radiation fields, such as interventional radiology, nuclear medicine and new developments. One of the ORAMED Working Tasks is addressed to the discussion and implementation in the radiation protection practice of the eye lens equivalent dose. The aim of this task group is to develop a personal dosemeter characterized in term of H{sub p}(3). Until now H{sub p}(3) conversion coefficients were not reported in the official recommendations and the available data were calculated for a 30 x 30 x 15 cm{sup 3} slab phantom that is far away to represent the head. A reduced slab phantom, for both calculating the quantities and type testing personal dosemeter in terms of the operational quantity, was previously proposed by ENEA Bologna team. The study demonstrated that a reduced slab phantom is better representative of a real situation, but the angular dependence of H{sub p}(3,{alpha}) due to the edges of the slab reduces its applicability. Therefore a better-suited phantom is proposed here. The dosimetric assessment in terms of this quantity is seldom performed in the various workplaces (e.g. hospitals) and therefore a question rises about its usefulness and practical implementation. The present work tries to introduce new elements in the discussion on the quantity H{sub p}(3) and to propose a more suitable theoretical cylindrical phantom (and a corresponding experimental one for the calibration procedures) to better approximate the head in which the eyes are placed.

  4. EBT-P proposed reference design report

    Energy Technology Data Exchange (ETDEWEB)

    Boch, A.L.

    1980-01-01

    This report describes the proposed reference design for the EBT-P proof-of-principle test device. The device described is a result of broad studies by many participating organizations from industry and from Department of Energy-sponsored fusion research groups, some working together and some in competitive studies, but all with the goal of defining a device at minimum cost and with maximum probability of meeting its goals. This design work is based upon advances in experimental and theoretical understanding of EBT achieved at Oak Ridge National Laboratory. The strategy adopted permits an initial test and validation of the key scaling properties of the ELMO Bumpy Torus concept, with a degree of built-in flexibility to extend the performance parameters toward the condition for containing a fusion reactor plasma. This will lead the way, then, to determination of a later power break-even demonstration and an eventual fusion reactor that can exploit the special high power-density and steady-state properties of the EBT concept.

    This Addendum establishes a new family of content envelopes consisting of small quantities of radioactive materials. These content envelopes and specific packing configurations are shown to be subcritical. However, the dose rates of some payloads must be measured and shown to comply with applicable radiation limits. Authorization for shipment of the content envelop requires acceptance of this Addendum by the DOE-HQ certifying official as a supplement to the 9977 SARP Revision 2 and DOE-HQ's subsequent revision of the CoC Revision 10 (which is based on SARP Addendum 2 and SARP Addendum 4) to authorize the additional content envelope. The Small Gram Quantity Content Envelopes and packing configurations will be incorporated in the next revision of the 9977 SARP.

  6. Okanogan Subbasin Water Quality and Quantity Report for Anadromous Fish in 2006.

    Energy Technology Data Exchange (ETDEWEB)

    Colville Tribes, Department of Fish & Wildlife

    2007-12-01

    Fish need water of sufficient quality and quantity in order to survive and reproduce. The list of primary water quality indicators appropriate for monitoring of anadromous fish, as identified by the Upper Columbia Monitoring Strategy, includes: discharge, temperature, dissolved oxygen, pH, turbidity, conductivity, nitrogen, phosphorus and ammonia. The Colville Tribes Fish and Wildlife Department began evaluating these water quality indicators in 2005 and this report represents data collected from October 1, 2005 through September 30, 2006. We collected empirical status and trend data from various sources to evaluate each water quality indicator along the main stem Okanogan and Similkameen Rivers along with several tributary streams. Each water quality indicator was evaluated based upon potential impacts to salmonid survival or productivity. Specific conductance levels and all nutrient indicators remained at levels acceptable for growth, survival, and reproduction of salmon and steelhead. These indicators were also considered of marginal value for monitoring environmental conditions related to salmonids within the Okanogan subbasin. However, discharge, temperature, turbidity, dissolved oxygen and pH in that order represent the water quality indicators that are most useful for monitoring watershed health and habitat changes and will help to evaluate threats or changes related to salmon and steelhead restoration and recovery. On the Okanogan River minimum flows have decreased over the last 12 years at a rate of -28.3CFS/year as measured near the town of Malott, WA. This trend is not beneficial for salmonid production and efforts to reverse this trend should be strongly encouraged. Turbidity levels in Bonaparte and Omak Creek were a concern because they had the highest monthly average readings. Major upland disturbance in the Bonaparte Creek watershed has occurred for decades and agricultural practices within the riparian areas along this creek have lead to major

  8. Report on the treatability study for inerting small quantities of radioactive explosives and explosive components

    Energy Technology Data Exchange (ETDEWEB)

    Loyola, V.M.; Reber, S.D.

    1996-02-01

    As a result of Sandia`s radiation hardening testing on a variety of its explosive components, radioactive waste streams were generated and have to be disposed of as radioactive waste. Due to the combined hazards of explosives and radioactivity, Sandia`s Radioactive and Mixed Waste Management organization did not have a mechanism for disposal of these waste streams. This report documents the study done to provide a method for the removal of the explosive hazard from those waste streams. The report includes the design of the equipment used, procedures followed, results from waste stream analog tests and the results from the actual explosive inerting tests on radioactive samples. As a result of the inerting treatment, the waste streams were rendered non-explosive and, thus, manageable through normal radioactive waste disposal channels.

  12. SU-E-T-596: P3DVHStats - a Novel, Automatic, Institution Customizable Program to Compute and Report DVH Quantities On Philips Pinnacle TPS

    Energy Technology Data Exchange (ETDEWEB)

    Wu, C [Sutter Medical Foundation, Roseville, CA (United States)

    2015-06-15

    Purpose: To implement a novel, automatic, institutional customizable DVH quantities evaluation and PDF report tool on Philips Pinnacle treatment planning system (TPS) Methods: An add-on program (P3DVHStats) is developed by us to enable automatic DVH quantities evaluation (including both volume and dose based quantities, such as V98, V100, D2), and automatic PDF format report generation, for EMR convenience. The implementation is based on a combination of Philips Pinnacle scripting tool and Java language pre-installed on each Pinnacle Sun Solaris workstation. A single Pinnacle script provide user a convenient access to the program when needed. The activated script will first export DVH data for user selected ROIs from current Pinnacle plan trial; a Java program then provides a simple GUI interface, utilizes the data to compute any user requested DVH quantities, compare with preset institutional DVH planning goals; if accepted by users, the program will also generate a PDF report of the results and export it from Pinnacle to EMR import folder via FTP. Results: The program was tested thoroughly and has been released for clinical use at our institution (Pinnacle Enterprise server with both thin clients and P3PC access), for all dosimetry and physics staff, with excellent feedback. It used to take a few minutes to use MS-Excel worksheet to calculate these DVH quantities for IMRT/VMAT plans, and manually save them as PDF report; with the new program, it literally takes a few mouse clicks in less than 30 seconds to complete the same tasks. Conclusion: A Pinnacle scripting and Java language based program is successfully implemented, customized to our institutional needs. It is shown to dramatically reduce time and effort needed for DVH quantities computing and EMR reporting.

    Rahmatinejad, A.; Razavi, R.; Kakavand, T.

    2015-07-01

    Thermodynamic quantities of 46Ti have been calculated in the framework of the BCS model with inclusion of modified nuclear pairing gap (MPBCS) that was proposed in our previous publication. Using modified paring gap results in an S-shaped heat capacity curve at critical temperature with a smooth behavior instead of singular behavior of the same curve in the BCS calculations. In addition the thermal quantities have been extracted within the framework of a canonical ensemble according to the new experimental data on nuclear level densities measured by the Oslo group. Comparison shows a good agreement between our calculations in MPBCS and the extracted quantities in the canonical ensemble framework.

  18. Monitoring, reporting and verification for national REDD + programmes: two proposals

    Energy Technology Data Exchange (ETDEWEB)

    Herold, Martin [Center for Geoinformation, Department of Environmental Science, Wageningen University, Droevendaalsesteeg 3, 6708 PB Wageningen (Netherlands); Skutsch, Margaret, E-mail: martin.herold@wur.nl [Centro de Investigaciones en GeografIa Ambiental, UNAM Campus Morelia (Mexico)

    2011-01-15

    Different options have been suggested by Parties to the UNFCCC (United Framework Convention on Climate Change) for inclusion in national approaches to REDD and REDD + (reduced deforestation, reduced degradation, enhancement of forest carbon stocks, sustainable management of forest, and conservation of forest carbon stocks). This paper proposes that from the practical and technical points of view of designing action for REDD and REDD + at local and sub-national level, as well as from the point of view of the necessary MRV (monitoring, reporting and verification), these should be grouped into three categories: conservation, which is rewarded on the basis of no changes in forest stock, reduced deforestation, in which lowered rates of forest area loss are rewarded, and positive impacts on carbon stock changes in forests remaining forest, which includes reduced degradation, sustainable management of forest of various kinds, and forest enhancement. Thus we have moved degradation, which conventionally is grouped with deforestation, into the forest management group reported as areas remaining forest land, with which it has, in reality, and particularly as regards MRV, much more in common. Secondly, in the context of the fact that REDD/REDD + is to take the form of a national or near-national approach, we argue that while systematic national monitoring is important, it may not be necessary for REDD/REDD + activities, or for national MRV, to be started at equal levels of intensity all over the country. Rather, areas where interventions seem easiest to start may be targeted, and here data measurements may be more rigorous (Tier 3), for example based on stakeholder self-monitoring with independent verification, while in other, untreated areas, a lower level of monitoring may be pursued, at least in the first instance. Treated areas may be targeted for any of the three groups of activities (conservation, reduced deforestation, and positive impact on carbon stock increases in

    2010-07-01

    The Ojibway Power and Energy Group (OPEG) is planning on installing a hydroelectric generating facility along the Namakan River at High Falls in Canada. In order the meet the different requirements in terms of environmental assessment for such a project, the group prepared an environmental report. The aim of this paper is to present the comments of the Quetico Foundation, a charity whose aim is to protect wilderness class parks. The foundation found both general and discipline-by-discipline deficiencies in OPEG's environmental report. All the deficiencies the Foundation observed are listed in this report, general deficiencies, and specific deficiencies concerning fisheries, terrestrial ecology, hydrology and socio-economic impacts. The Quetico Foundation demonstrated that a significant number of deficiencies are found in the OPEG environmental report, suggesting that they did not fully understand the potential long term impacts of their project and that further study should be undertaken.

    2013-09-01

    Full Text Available Recently, there has been a massive infrastructure development and an increasing demand for public and private housing, resulting in a shortage of qualified quantity surveyors. This study aims to forecast the demand for qualified quantity surveyors in Hong Kong from 2013 to 2015. Literature review indicates that the demand for quantity surveyors is a function of the gross values of building, civil engineering and maintenance works. The proposed forecasting method consists of two steps. The first step is to estimate the gross values of building, civil engineering and maintenance works by time series methods and the second step is to forecast the manpower demand for quantity surveyors by causal methods. The data for quantity surveyors and construction outputs are based on the ‘manpower survey reports of the building and civil engineering industry’ and the ‘gross value of construction works performed by main contractors’ respectively. The forecasted manpower demand for quantity surveyors in 2013, 2014 and 2015 are 2,480, 2,632 and 2,804 respectively. Due to the low passing rate of the assessment of professional competence (APC and the increasing number of retired qualified members, there will be a serious shortage of qualified quantity surveyors in the coming three years.

  18. Monte Carlo studies on water and LiF cavity properties for dose-reporting quantities when using x-ray and brachytherapy sources

    Science.gov (United States)

    Soares Lopes Branco, Isabela; Guimarães Antunes, Paula Cristina; Paiva Fonseca, Gabriel; Yoriyaz, Hélio

    2016-12-01

    Model-based dose calculation algorithms (MBDCAs) are the current tools to estimate dose in brachytherapy, which takes into account heterogeneous medium, therefore, departing from water-based formalism (TG-43). One aspect associated to MBCDA is the choice of dose specification medium since it offers two possibilities to report dose: (a) dose to medium in medium, D m,m; and (b) dose to water in medium, D w,m. The discussion about the preferable quantity to be reported is underway. The dose conversion factors, DCF, between dose to water in medium, D w,m, and dose to medium in medium, D m,m, is based on cavity theory and can be obtained using different approaches. When experimental dose verification is desired using, for example, thermoluminescent LiF dosimeters, as in in vivo dose measurements, a third quantity is obtained, which is the dose to LiF in medium, D LiF,m. In this case, DCF to convert from D LiF,m to D w,m or D m,m is necessary. The objective of this study is to estimate DCFs using different approaches, present in the literature, quantifying the differences between them. Also, dose in water and LiF cavities in different tissue media and respective conversion factors to be able to convert LiF-based dose measured values into dose in water or tissue were obtained. Simple cylindrical phantoms composed by different tissue equivalent materials (bone, lung, water and adipose) are modelled. The phantoms contain a radiation source and a cavity with 0.002 69 cm3 in size, which is a typical volume of a disc type LiF dosimeter. Three x-rays qualities with average energies ranging from 47 to 250 keV, and three brachytherapy sources, 60Co, 192Ir and 137Cs, are considered. Different cavity theory approaches for DCF calculations and different cavity/medium combinations have been considered in this study. DCF values for water/bone and LiF/bone cases have strong dependence with energy increasing as the photon energy increases. DCF values also increase with energy for

    The ability in animals to count and represent different numbers of objects has received a great deal of attention in the past few decades. Cumulative evidence from comparative studies on number discriminations report obvious analogies among human babies, non-human primates and birds and are consistent with the hypothesis of two distinct and widespread mechanisms, one for counting small numbers (verbal creatures studied; results are in agreement with the hypothesis of the existence of two distinct systems for quantity discrimination in vertebrates.

    2015-07-15

    Thermodynamic quantities of {sup 46}Ti have been calculated in the framework of the BCS model with inclusion of modified nuclear pairing gap (MPBCS) that was proposed in our previous publication. Using modified paring gap results in an S-shaped heat capacity curve at critical temperature with a smooth behavior instead of singular behavior of the same curve in the BCS calculations. In addition the thermal quantities have been extracted within the framework of a canonical ensemble according to the new experimental data on nuclear level densities measured by the Oslo group. Comparison shows a good agreement between our calculations in MPBCS and the extracted quantities in the canonical ensemble framework.

  5. Intermediate dosimetric quantities.

    Science.gov (United States)

    Kellerer, A M; Hahn, K; Rossi, H H

    1992-04-01

    The transfer of energy from ionizing radiation to matter involves a series of steps. In wide ranges of their energy spectra photons and neutrons transfer energy to an irradiated medium almost exclusively by the production of charged particles which ionize and thereby produce electrons that can ionize in turn. The examination of these processes leads to a series of intermediate quantities. One of these is kerma, which has long been employed as a measure of the energy imparted in the first of the interactions. It depends only on the fluence of uncharged particles and is therefore--unlike absorbed dose and electron fluence--insensitive to local differences of receptor geometry and composition. An analogous quantity for charged-particle fields, cema (converted energy per unit mass), is defined, which quantifies the energy imparted in terms of the interactions of charged particles, disregarding energy dissipation by secondary electrons. Cema can be expressed as an integral over the fluence of ions times their stopping power. However, complications arise when the charged particles are electrons, and when their fluence cannot be separated from that of the secondaries. The resulting difficulty can be circumvented by the definition of reduced cema. This quantity corresponds largely to the concept employed in the cavity theory of Spencer and Attix. In reduced cema not all secondary electrons but all electrons below a chosen cutoff energy, delta, are considered to be absorbed locally. When the cutoff energy is reduced, cema approaches absorbed dose and thereby becomes sensitive to highly local differences in geometry or composition. With larger values of delta, reduced cema is a useful parameter to specify the dose-generating potential of a charged-particle field 'free in air' or in vacuo. It is nearly equal to the mean absorbed dose in a sphere with radius equal to the range of electrons of energy delta. Reduced cema is a function of the fluence at the specified location at

  7. 1972 preliminary safety analysis report based on a conceptual design of a proposed repository in Kansas

    Energy Technology Data Exchange (ETDEWEB)

    Blomeke, J.O.

    1977-08-01

    This preliminary safety analysis report is based on a proposed Federal Repository at Lyons, Kansas, for receiving, handling, and depositing radioactive solid wastes in bedded salt during the remainder of this century. The safety analysis applies to a hypothetical site in central Kansas identical to the Lyons site, except that it is free of nearby salt solution-mining operations and bore holes that cannot be plugged to Repository specifications. This PSAR contains much information that also appears in the conceptual design report. Much of the geological-hydrological information was gathered in the Lyons area. This report is organized in 16 sections: considerations leading to the proposed Repository, design requirements and criteria, a description of the Lyons site and its environs, land improvements, support facilities, utilities, different impacts of Repository operations, safety analysis, design confirmation program, operational management, requirements for eventually decommissioning the facility, design criteria for protection from severe natural events, and the proposed program of experimental investigations.

  17. Reporting Islam in Australian Newspapers: the case of the proposed Elermore Vale mosque

    Directory of Open Access Journals (Sweden)

    Caitlin McGregor

    2013-10-01

    Full Text Available This paper uses the local case study of a proposed mosque development in the Newcastle suburb of Elermore Vale as an example of how Islam has been reported in the Australian media. The media reports analysed were published in Newcastle's local newspaper The Herald between February 2010, when the Newcastle Muslim Association purchased the land for the proposed development, and March 2012, when the Land and Environment Court ruled against the proposal. The discourses evident in the newspaper content reveal a clear undercurrent of racism within the local reporting against the Muslim community and, it may be argued, are representative of a larger trend of Islamophobia in the West. While the key community protest group Elermore Vale Community for Appropriate Residential and Environment Strategies (EV CARES attempted to discuss the mosque proposal by raising planning issues appropriate property development matters, anti­Muslim sentiment was clearly evident in many of the articles.Illustrations of Edward Said's (1978, 2004 concept of 'Orientalism' emerged through the reporting, where Islam, and by extension the Newcastle Muslim Association, was portrayed as being different, strange and threatening to the local community. The fact that this kind of anti­Muslim sentiment can be identified in local media products is indicative of the challenges for local media groups covering local media events, as it represents how a local matter can become contentious due to globally recognised concerns. In this instance, those concerns are the perceived threat of Muslim fundamentalism and Islam to the West. Discursive analysis of The Herald's reports demonstrates that discourses of power, religion, 'the Other', 'community' and 'the victim' are prevalently portrayed. Furthermore, these portrayals contribute to anti­Muslim attitudes communicated by key parties in the articles, who use the Islamic religion as an identifier; the marginalisation of the Muslim community

  18. Final technical evaluation report for the proposed revised reclamation plan for the Atlas Corporation Moab Mill

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1997-03-01

    This final Technical Evaluation Report (TER) summarizes the US Nuclear Regulatory Commission staff`s review of Atlas Corporation`s proposed reclamation plan for its uranium mill tailings pile near Moab, Utah. The proposed reclamation would allow Atlas to (1) reclaim the tailings pile for permanent disposal and long-term custodial care by a government agency in its current location on the Moab site, (2) prepare the site for closure, and (3) relinquish responsibility of the site after having its NRC license terminated. The NRC staff concludes that, subject to license conditions identified in the TER, the proposed reclamation plan meets the requirements identified in NRC regulations, which appear primarily in 10 CFR Part 40. 112 refs., 6 figs., 16 tabs.

  19. A community standard for immunogenomic data reporting and analysis: proposal for a STrengthening the REporting of Immunogenomic Studies statement.

    Science.gov (United States)

    Hollenbach, J A; Mack, S J; Gourraud, P-A; Single, R M; Maiers, M; Middleton, D; Thomson, G; Marsh, S G E; Varney, M D

    2011-11-01

    Modern high-throughput HLA and KIR typing technologies are generating a wealth of immunogenomic data with the potential to revolutionize the fields of histocompatibility and immune-related disease association and population genetic research, much as SNP-based approaches have revolutionized association research. The STrengthening the REporting of Genetic Association studies (STREGA) statement provides community-based data reporting and analysis standards for genomic disease-association studies, identifying specific areas in which adoption of reporting guidelines can improve the consistent interpretation of genetic studies. While aspects of STREGA can be applied to immunogenomic studies, HLA and KIR research requires additional consideration, as the high levels of polymorphism associated with immunogenomic data pose unique methodological and computational challenges to the synthesis of information across datasets. Here, we outline the principle challenges to consistency in immunogenomic studies, and propose that an immunogenomic-specific analog to the STREGA statement, a STrengthening the REporting of Immunogenomic Studies (STREIS) statement, be developed as part of the 16th International HLA and Immunogenetics Workshop. We propose that STREIS extends at least four of the 22 elements of the STREGA statement to specifically address issues pertinent to immunogenomic data: HLA and KIR nomenclature, data-validation, ambiguity resolution, and the analysis of highly polymorphic genetic systems. As with the STREGA guidelines, the intent behind STREIS is not to dictate the design of immunogenomic studies, but to ensure consistent and transparent reporting of research, facilitating the synthesis of HLA and KIR data across studies.

  1. Surgery in extensive vertebral hemangioma: case report, literature review and a new algorithm proposal.

    Science.gov (United States)

    Tarantino, Roberto; Donnarumma, Pasquale; Nigro, Lorenzo; Delfini, Roberto

    2015-07-01

    Hemangiomas are benign dysplasias or vascular tumors consisting of vascular spaces lined with endothelium. Nowadays, radiotherapy for vertebral hemangiomas (VHs) is widely accepted as primary treatment for painful lesions. Nevertheless, the role of surgery is still unclear. The purpose of this study is to propose a novel algorithm of treatment about VHs. This is a case report of an extensive VH and a review of the literature. A case of vertebral fracture during radiotherapy at a total dose of 30 Gy given in 10 fractions (treatment time 2 weeks) using a linear accelerator at 15 MV high-energy photons for extensive VH is reported. Using PubMed database, a review of the literature is done. The authors have no study funding sources. The authors have no conflicting financial interests. In the literature, good results in terms of pain and neurological deficits are reported. No cases of vertebral fractures are described. However, there is no consensus regarding the treatment for VHs. Radiotherapy is widely utilized in VHs determining pain. Surgery for VHs determining neurological deficit is also widely accepted. Perhaps, regarding the width of the lesion, no indications are given. We consider it important to make an evaluation before initiating the treatment for the risk of pathologic vertebral fracture, since in radiotherapy, there is no convention regarding structural changes determined in VHs. We propose a new algorithm of treatment. We recommend radiotherapy only for small lesions in which vertebral stability is not concerned. Kyphoplasty can be proposed for asymptomatic patients in which VHs are small and in patients affected by VHs determining pain without spinal canal invasion in which the VH is small. In patients affected by pain without spinal canal invasion but in which the VH is wide or presented with spinal canal invasion and in patients affected by neurological deficits, we propose surgery.

  2. Reporting quality of survival analyses in medical journals still needs improvement. A minimal requirements proposal.

    Abraira, Víctor; Muriel, Alfonso; Emparanza, José I; Pijoan, José I; Royuela, Ana; Plana, María Nieves; Cano, Alejandra; Urreta, Iratxe; Zamora, Javier

    2013-12-01

    We reviewed publications with two main objectives: to describe how survival analyses are reported across medical journal specialties and to evaluate changes in reporting across periods and journal specialties. Systematic review of clinical research articles published in 1991 and 2007, in 13 high-impact medical journals. The number of articles performing survival analysis published in 1991 (104) and 2007 (240) doubled (17% vs. 33.5%; P = 0.000), although not uniformly across specialties. The percentage of studies using regression models and the number of patients included also increased. The presentation of results improved, although only the reporting of precision of effect estimates reached satisfactory levels (53.1% in 1991 vs. 94.2% in 2007; P = 0.000). Quality of reporting also varied across specialties; for example, cardiology articles were less likely than oncology ones to discuss sample size estimation (odds ratio = 0.12; 95% confidence interval: 0.05, 0.30). We also detected an interaction effect between period and specialty regarding the likelihood of reporting precision of curves and precision of effect estimates. The application of survival analysis to medical research data is increasing, whereas improvement in reporting quality is slow. We propose a list of minimum requirements for improved application and description of survival analysis. Copyright © 2013 Elsevier Inc. All rights reserved.

Twenty-seven wildlife species of special interest (protected, sensitive, furbearer, game animal, etc.), and waterfowl, were observed on the proposed expansion area. Bird censuses revealed 13 raptorial species (including four of special interest: bald eagle, golden eagle, osprey, and prairie falcon); five upland game bird species (sage grouse, California quail, chukar, gray partridge, and ring-necked pheasant); common loons (a species proposed for state listing as threatened); and five other species of special interest (sage thrasher, loggerhead shrike, mourning dove, sage sparrow, and long-billed curlew). Estimates of waterfowl abundance are included for the Priest Rapids Pool of the Columbia River. Six small mammal species were captured during this study; one, the sagebrush vole, is a species of special interest. Two large animal species, mule deer and elk, were noted on the site. Five species of furbearing animals were observed (coyote, beaver, raccoon, mink, and striped skunk). Four species of reptiles and one amphibian were noted. Fisheries surveys were conducted to document the presence of gamefish, and sensitive-classified fish and aquatic invertebrates. Rainbow trout were the only fish collected within the boundaries of the proposed northern expansion area. 22 refs., 10 figs., 4 tabs.

    Recent years have witnessed the emergence of a new class of social networks, which require us to move beyond previously employed representations of complex graph structures. A notable example is that of the folksonomy, an online process where users collaboratively employ tags to resources to impart structure to an otherwise undifferentiated database. In a recent paper, we proposed a mathematical model that represents these structures as tripartite hypergraphs and defined basic topological quantities of interest. In this paper, we extend our model by defining additional quantities such as edge distributions, vertex similarity and correlations as well as clustering. We then empirically measure these quantities on two real life folksonomies, the popular online photo sharing site Flickr and the bookmarking site CiteULike. We find that these systems share similar qualitative features with the majority of complex networks that have been previously studied. We propose that the quantities and methodology described here can be used as a standard tool in measuring the structure of tagged networks.

  5. Law of genome evolution direction: Coding information quantity grows

    The problem of the directionality of genome evolution is studied. Based on the analysis of C-value paradox and the evolution of genome size, we propose that the function-coding information quantity of a genome always grows in the course of evolution through sequence duplication, expansion of code,and gene transfer from outside. The function-coding information quantity of a genome consists of two parts, p-coding information quantity that encodes functional protein and n-coding information quantity that encodes other functional elements. The evidences on the law of the evolutionary directionality are indicated. The needs of function are the motive force for the expansion of coding information quantity,and the information quantity expansion is the way to make functional innovation and extension for a species. Therefore, the increase of coding information quantity of a genome is a measure of the acquired new function, and it determines the directionality of genome evolution.

    2016-06-24

    Lesch-Nyhan syndrome (LNS) is an X-linked recessive disorder caused by a deficiency of hypoxanthine-guanine phosphoribosyltransferase (HPRT), an enzyme encoded by the HPRT1 gene. The classic disease phenotype described by Lesch and Nyhan in 1964 includes hyperuricemia, mental retardation, severe motor deficiency, and recurring self-mutilation. Here, we report the case of a family with 4 affected males and several female obligate carriers. In 1989, Fujimori et al. reported on a patient diagnosed with LNS who had an HPRT variant thereafter codenamed HPRTYale. The same patient was studied by Wilson et al. in 1986, who found no detectable HPRT enzymatic activity, even though normal HPRT mRNA and protein levels were observed. Disease severity is closely related to residual enzymatic activity, which fits the phenotype presented for this previously reported case, as well as for the patients we report on herein. As it has been reported in only one patient, this mutation is still considered a variant of unknown significance. The HPRTYale mutation is a G>C transversion that leads to a different amino acid with different biochemical properties at position 71, potentially causing the major lack of function. To evaluate the impact of this variant, we used the PolyPhen-2 software, which classified it as possibly damaging. Furthermore, the frequency of this mutant allele is likely extremely rare, since it has only been reported on twice, and a population frequency is not yet available. In conclusion, we propose that the HPRTYale variant is pathogenic, and should be included on lab reports hereafter.

    This report summarizes the results of an environmental survey conducted at sites associated with the proposed Uranium Processing Facility (UPF) at the Y-12 National Security Complex in September-October 2009. The survey was conducted in order to evaluate potential impacts of the overall project. This project includes the construction of a haul road, concrete batch plant, wet soil storage area and dry soil storage area. The environmental surveys were conducted by natural resource experts at ORNL who routinely assess the significance of various project activities on the Oak Ridge Reservation (ORR). Natural resource staff assistance on this project included the collection of environmental information that can aid in project location decisions that minimize impacts to sensitive resource such as significant wildlife populations, rare plants and wetlands. Natural resources work was conducted in various habitats, corresponding to the proposed areas of impact. Thc credentials/qualifications of the researchers are contained in Appendix A. The proposed haul road traverses a number of different habitats including a power-line right-of-way. wetlands, streams, forest and mowed areas. It extends from what is known as the New Salvage Yard on the west to the Polaris Parking Lot on the east. This haul road is meant to connect the proposed concrete batch plant to the UPF building site. The proposed site of the concrete batch plant itself is a highly disturbed fenced area. This area of the project is shown in Fig. 1. The proposed Wet Soils Disposal Area is located on the north side of Bear Creek Road at the former Control Burn Study Area. This is a second growth arce containing thick vegetation, and extensive dead and down woody material. This area of the project is shown in Fig. 2. Thc dry soils storage area is proposed for what is currently known as the West Borrow Area. This site is located on the west side of Reeves Road south of Bear Creek Road. The site is an early successional

    Okanagan River sockeye salmon, which spawn near the town of Oliver, B.C., have their farther upstream migration limited by several water control and diversion dams. Stock numbers have been declining for many years and the Okanagan Native Alliance Fisheries Department (ONAFD) has been the principal advocate of a program to restore their numbers and range by reintroducing them into upstream waters where they may once have occurred in substantial numbers Some investigators have warned that without effective intervention Okanagan sockeye are at considerable risk of extinction. Among a host of threats, the quality of water in the single nursery areas in Osoyoos Lake. is deteriorating and a sanctuary such as that afforded in larger lakes higher in the system could be essential. Because the proposed reintroduction upstream has implications for other fish species, (particularly kokanee, the so-called ''landlocked sockeye'' which reside in many Okanagan lakes), the proponents undertook a three-year investigation, with funding from the Bonneville Power Administration and the Confederated Tribes of the Colville Reservation, to identify possible problem areas, and they committed to an interim experimental reintroduction to Skaha Lake where any problems could be worked out before a more ambitious reintroduction, (e.g. to Okanagan Lake) could be formally considered. The three-year investigation was completed in the spring of 2003. It included an assessment of risks from disease or the possible introduction of unwanted exotic species. It also considered the present quality and quantity of sockeye habitat, and opportunities for expanding or improving it. Finally ecological complexity encouraged the development of a life history model to examine interactions of sockeye with other fishes and their food organisms. While some problem areas were exposed in the course of these studies, they appeared to be manageable and the concept of an experimental reintroduction

    Rácz, István

    2016-01-01

    In [11] a proposal was made to construct initial data for binary black hole configurations. It was done by using the parabolic-hyperbolic form of the constraints and choosing the free data provided by superposed Kerr-Schild black holes. The proposal of [11] do also apply to multiple systems involving generic Kerr-Schild black holes. Notably, the specific choice made for the free data allows---without making detailed use of the to be solutions to the constraints---to determine explicitly, the ADM quantities of the multiple system in terms of the separations velocities and spins of the individual Kerr-Schild black holes.

  12. Traumatic subarachnoid pleural fistula in children: case report, algorithm and classification proposal

    Directory of Open Access Journals (Sweden)

    Moscote-Salazar Luis Rafael

    2016-06-01

    Full Text Available Subarachnoid pleural fistulas are rare. They have been described as complications of thoracic surgery, penetrating injuries and spinal surgery, among others. We present the case of a 3-year-old female child, who suffer spinal cord trauma secondary to a car accident, developing a posterior subarachnoid pleural fistula. To our knowledge this is the first reported case of a pediatric patient with subarachnoid pleural fistula resulting from closed trauma, requiring intensive multimodal management. We also present a management algorithm and a proposed classification. The diagnosis of this pathology is difficult when not associated with neurological deficit. A high degree of suspicion, multidisciplinary management and timely surgical intervention allow optimal management.

    Full Text Available This article describes the interdisciplinary approach currently used at the Manguinhos Municipal Health Centre (MMHC, Rio de Janeiro, for the longitudinal management of anti-smoking treatment in patients living in low-income community regions, from the perspective of a medical student in his rotating internship. The anti-tobacco approach consists in a longitudinal therapy divided in two steps: (i four interdisciplinary anti-tobacco group sessions scheduled weekly, which includes psychotherapy and pharmacological resources; followed by (ii two sessions of maintenance therapy scheduled fortnightly, characterized by individualized care and pharmacological withdrawal, complemented by a monthly one year follow-up. This article describes the current protocols, the professional activities and how the proposal was developed. This report suggests that improvement in medical training might occur through participation of medical students in health education activities such as tobacco cessation group. 

  14. Assessing and reporting heterogeneity in treatment effects in clinical trials: a proposal

    Directory of Open Access Journals (Sweden)

    Kent David M

    2010-08-01

    Full Text Available Abstract Mounting evidence suggests that there is frequently considerable variation in the risk of the outcome of interest in clinical trial populations. These differences in risk will often cause clinically important heterogeneity in treatment effects (HTE across the trial population, such that the balance between treatment risks and benefits may differ substantially between large identifiable patient subgroups; the "average" benefit observed in the summary result may even be non-representative of the treatment effect for a typical patient in the trial. Conventional subgroup analyses, which examine whether specific patient characteristics modify the effects of treatment, are usually unable to detect even large variations in treatment benefit (and harm across risk groups because they do not account for the fact that patients have multiple characteristics simultaneously that affect the likelihood of treatment benefit. Based upon recent evidence on optimal statistical approaches to assessing HTE, we propose a framework that prioritizes the analysis and reporting of multivariate risk-based HTE and suggests that other subgroup analyses should be explicitly labeled either as primary subgroup analyses (well-motivated by prior evidence and intended to produce clinically actionable results or secondary (exploratory subgroup analyses (performed to inform future research. A standardized and transparent approach to HTE assessment and reporting could substantially improve clinical trial utility and interpretability.

  15. Environmental assessment report: Nuclear Test Technology Complex. [Construction and operation of proposed facility

    Energy Technology Data Exchange (ETDEWEB)

    Tonnessen, K.; Tewes, H.A.

    1982-08-01

    The US Department of Energy (USDOE) is planning to construct and operate a structure, designated the Nuclear Test Technology Complex (NTTC), on a site located west of and adjacent to the Lawrence Livermore National Laboratory. The NTTC is designed to house 350 nuclear test program personnel, and will accommodate the needs of the entire staff of the continuing Nuclear Test Program (NTP). The project has three phases: land acquisition, facility construction and facility operation. The purpose of this environmental assessment report is to describe the activities associated with the three phases of the NTTC project and to evaluate potential environmental disruptions. The project site is located in a rural area of southeastern Alameda County, California, where the primary land use is agriculture; however, the County has zoned the area for industrial development. The environmental impacts of the project include surface disturbance, high noise levels, possible increases in site erosion, and decreased air quality. These impacts will occur primarily during the construction phase of the NTTC project and can be mitigated in part by measures proposed in this report.

  17. Comprehensive Report For Proposed Elevated Temperature Elastic Perfectly Plastic (EPP) Code Cases Representative Example Problems

    Energy Technology Data Exchange (ETDEWEB)

    Hollinger, Greg L. [Idaho National Lab. (INL), Idaho Falls, ID (United States)

    2014-06-01

    Background: The current rules in the nuclear section of the ASME Boiler and Pressure Vessel (B&PV) Code , Section III, Subsection NH for the evaluation of strain limits and creep-fatigue damage using simplified methods based on elastic analysis have been deemed inappropriate for Alloy 617 at temperatures above 1200F (650C)1. To address this issue, proposed code rules have been developed which are based on the use of elastic-perfectly plastic (E-PP) analysis methods and which are expected to be applicable to very high temperatures. The proposed rules for strain limits and creep-fatigue evaluation were initially documented in the technical literature 2, 3, and have been recently revised to incorporate comments and simplify their application. The revised code cases have been developed. Task Objectives: The goal of the Sample Problem task is to exercise these code cases through example problems to demonstrate their feasibility and, also, to identify potential corrections and improvements should problems be encountered. This will provide input to the development of technical background documents for consideration by the applicable B&PV committees considering these code cases for approval. This task has been performed by Hollinger and Pease of Becht Engineering Co., Inc., Nuclear Services Division and a report detailing the results of the E-PP analyses conducted on example problems per the procedures of the E-PP strain limits and creep-fatigue draft code cases is enclosed as Enclosure 1. Conclusions: The feasibility of the application of the E-PP code cases has been demonstrated through example problems that consist of realistic geometry (a nozzle attached to a semi-hemispheric shell with a circumferential weld) and load (pressure; pipe reaction load applied at the end of the nozzle, including axial and shear forces, bending and torsional moments; through-wall transient temperature gradient) and design and operating conditions (Levels A, B and C).

  18. Relative quantity judgments in South American sea lions (Otaria flavescens).

    Science.gov (United States)

    Abramson, José Z; Hernández-Lloreda, Victoria; Call, Josep; Colmenares, Fernando

    2011-09-01

    There is accumulating evidence that a variety of species possess quantitative abilities although their cognitive substrate is still unclear. This study is the first to investigate whether sea lions (Otaria flavescens), in the absence of training, are able to assess and select the larger of two sets of quantities. In Experiment 1, the two sets of quantities were presented simultaneously as whole sets, that is, the subjects could compare them directly. In Experiment 2, the two sets of quantities were presented item-by-item, and the totality of items was never visually available at the time of choice. For each type of presentation, we analysed the effect of the ratio between quantities, the difference between quantities and the total number of items presented. The results showed that (1) sea lions can make relative quantity judgments successfully and (2) there is a predominant influence of the ratio between quantities on the subjects' performance. The latter supports the idea that an analogue representational mechanism is responsible for sea lions' relative quantities judgments. These findings are consistent with previous reports of relative quantities judgments in other species such as monkeys and apes and suggest that sea lions might share a similar mechanism to compare and represent quantities.

The 99-acre STAR Center is located in Largo, Florida. The Northeast Site is located in the northeast corner of the STAR Center. The Northeast Site meets all the requirements for an RMO II closure—No Further Action with Controls. DOE is nearing completion of a restrictive covenant for the Northeast Site. DOE has completed post-active-remediation monitoring at the Northeast Site as of September 2012. No additional monitoring will be conducted.

  1. Target registration and target positioning errors in computer-assisted neurosurgery: proposal for a standardized reporting of error assessment.

    Science.gov (United States)

    Widmann, Gerlig; Stoffner, Rudolf; Sieb, Michael; Bale, Reto

    2009-12-01

    Assessment of errors is essential in development, testing and clinical application of computer-assisted neurosurgery. Our aim was to provide a comprehensive overview of the different methods to assess target registration error (TRE) and target positioning error (TPE) and to develop a proposal for a standardized reporting of error assessment. A PubMed research on phantom, cadaver or clinical studies on TRE and TPE has been performed. Reporting standards have been defined according to (a) study design and evaluation methods and (b) specifications of the navigation technology. The proposed standardized reporting includes (a) study design (controlled, non-controlled), study type (non-anthropomorphic phantom, anthropomorphic phantom, cadaver, patient), target design, error type and subtypes, space of TPE measurement, statistics, and (b) image modality, scan parameters, tracking technology, registration procedure and targeting technique. Adoption of the proposed standardized reporting may help in the understanding and comparability of different accuracy reports. Copyright (c) 2009 John Wiley & Sons, Ltd.

  11. Development of Digital Computation of Building and Civil Engineering Quantities

    Directory of Open Access Journals (Sweden)

    Aderinola, O.S

    2014-06-01

    Full Text Available The work of Building and Civil engineering demands a greater knowledge, skill and precision in quantity estimation.The manual method of estimating quantities for building and civil engineering works has posed potential problem areas on work that is undertaken. The low reliability of manual estimation indicates discrepancies in the accuracy of quantities computed manually,hence,the introduction of a digital computation.It is envisaged that this method will greatly reduce the complexities of different aspects when computing quantities for projects, as well as reduce the time to complete the computation and therefore projects can be started earlier.The paper reviewed the procedures involved in the development of a computer program for the digital computation of Building and Civil engineering quantities.The program was developed using Microsoft Visual C SHARP (C# programming language and Microsoft Visual studio. The steps/procedure used in achieving the development of the computer program was (1.designing the application interface,(2 adding controls to the window and (3writing codes behind the interface.The digital computation was tested using a proposed Road project and a proposed administrative buildingand the results showed an average of 100% of the items has 0 to 10 percentage difference for the road and 92% for the building in the final outputs of the quantities obtained through the manual computation and the digital computation and the software could therefore be said to be accurate and reliable.

    Bakota, Bore; Kopljar, Mario; Jurjević, Zoran; Staresinić, Mario; Cvjetko, Ivan; Dobrić, Ivan; De Faoite, Diarmuid

    2012-12-01

    Treatment of a mangled lower extremity represents a major challenge. The decision whether to amputate or attempt reconstruction is currently based upon surgical evaluation. The aim of this paper is to propose a new approach to surgical evaluation based on scoring systems, local clinical status of the patient as well as comorbidities, mechanism of trauma and hospital resources. Available literature regarding this topic was evaluated and a case of patient with mangled extremity is presented. Based on current literature guidelines and evidence-based medicine, management for borderline cases is proposed to aid clinical decision making in these situations. We describe a 44-year old male patient who presented with mangled lower left leg. Despite a borderline Mangled Extremity Severity Score (MESS), due to the overall health status of the patient and local clinical status with preserved plantar sensitivity and satisfactory capillary perfusion, reconstruction was attempted. After 6 months of treatment, all wounds healed completely with no pain, and satisfactory motor and sensory function was achieved. In conclusion, the treatment of mangled extremity treatment should be based on evidence based literature along with a clinical evaluation of every individual patient. Scores are helpful, but should not be taken as the sole indication for amputation.

  10. Assessment of seafloor burial of proposed OTEC power transmission cables. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Tate, K.W.; Chern, C.; Tudor, W.J.

    1982-01-01

    This study assesses the need for protection of the seafloor OTEC power transmission cables, identifies the means, or development requirements for accomplishing the required protection, and determines the costs and benefits associated with this protection. Protection of the bottom cable along the entire route from the shoreline to the riser cable were evaluated at four specific sites. These sites were chosen mainly to represent the rather diverse bottom conditions expected in the OTEC program. Three of the four sites are island sites; they are immediately offshore of: (1) Kahe Point, Oahu, Hawaii; (2) Punta Yeguas, Puerto Rico; and (3) Cabras Island, Guam. The fourth site is in the Gulf of Mexico, due west of Tampa, Florida. A total of 1061 submarine communication cable faults were accumulated and analyzed during the initial portion of this study. For three of the proposed OTEC sites, namely Hawaii, Puerto Rico and Guam, a 90% chance of avoiding the hazards of chafing, corrosion, anchors, and trawling can be achieved by using the proper protection techniques over approximately 1 to 2 nautical miles from shore. The status of seafloor cable protection technology is also addressed in this study. A comprehensive summary identifying the most suitable commercial system has been conducted. Both cable and pipeline protection systems were included as well as previous relevant experience and operating conditions. Guidelines, methods, and procedures for cable protection are given in general for the four proposed OTEC plant sites and cable routes, together with seafloor scenarios and protection strategies for each of the four sites.

    Four helium-3 (3He) detector/preamplifier packages (¾”/KM200, DDSI/PDT-A111, DDA/PDT-A111, and DDA/PDT10A) were experimentally tested to determine the deadtime effects at different DT neutron generator output settings. At very high count rates, the ¾”/KM200 package performed best. At high count rates, the ¾”/KM200 and the DDSI/PDT-A111 packages performed very well, with the DDSI/PDT-A111 operating with slightly higher efficiency. All of the packages performed similarly at mid to low count rates. Proposed improvements include using a fast recovery LANL-made dual channel preamplifier, testing smaller diameter 3He tubes, and further investigating quench gases.

  12. Microgravity crystallization of macromolecules: An interim report and proposal for continued research

    Science.gov (United States)

    Goldberg, Benjamin E.

    1986-01-01

    An initial investigation exploring the effects of gravity on the crystallization of macromolecular systems has been completed. Monodisperse poly(ethylene), molecular weight 48,000 was melted and recrystallized under gravitational conditions: 0, 1, and 2 g. No correlations to gravitational environment were noted for the 20 C/min melt, as monitored with a photodensitometer system. However, post-crystallization testing of the recrystallized samples revealed thicker samples with more regions of large, well defined spherulites for the zero gravity crystallization environment. The results of the post-crystallization analysis have been reviewed and the results related to nucleation concerns. Finally, birefringence data, consistent with, but not explained by, the nucleation scenarios is detailed, and further investigations are proposed.

  16. Clinically Amyopathic Dermatomyositis Complicated by Pleural Effusion Case Report, Literature Review, and Proposed Mechanism.

    Science.gov (United States)

    Wu, Ying; Chhaya, Sheetal; Hurowitz, Bert; Ardiles, Thomas; Carlson, Richard

    2015-07-01

    Polymyositis-dermatomyositis (PM-DM) is a chronic inflammatory disorder that mainly involves muscles and skin. Clinically amyopathic dermatomyositis (CADM) is a unique subset of PM-DM with typical skin manifestations but little or no evidence of musculoskeletal involvement. Many cases of dermatomyositis and CADM are associated with internal malignancy, but pulmonary manifestations can also been seen; the most common of which is interstitial lung disease. Pleural effusion is a rare complication and may be difficult to differentiate from other causes, such as infections, heart failure, or malignancy. We report a patient with CADM complicated by rapidly progressive pleural effusions. Based on findings of this patient, as well as literature review, we suggest that the etiology of massive pleural effusion in this setting is most likely related to local immune pleuritis associated with underlying interstitial lung disease due to dermatomyositis. Optimal management should be individualized and may include immunosuppressive agents, as well as antimicrobials, and potentially other agents.

  17. Nuclear Physics Laboratory, University of Colorado technical progress report, 1976 and proposal for continuation of contract

    Energy Technology Data Exchange (ETDEWEB)

    1976-11-01

    This report summarizes the work carried out at the Nuclear Physics Laboratory of the University of Colorado during the period November 1, 1975 to November 1, 1976. The low energy nuclear physics section is dominated by light-ion reaction studies which span a wide range. These include both two-neutron and two-proton transfer reactions, charge exchange and inelastic scattering, as well as single nucleon transfer reactions. The nuclei studied vary widely in their mass and characteristics. These reaction studies have been aided by the multi-use scattering chamber which now allows the energy-loss-spectrometer beam preparation system (beam swinger) to shift from charged particle studies to neutron time-of-flight studies with a minimum loss of time. The intermediate energy section reflects the increase in activity accompanying the arrival of LAMPF data and the initiation of (p,d) studies at the Indiana separated-sector cyclotron. The nucleon removal results provided by the ..pi.. beam at EPICS previous to completion of the spectrometer have shown that nuclear effects dominate this process, so that the widely used free interaction picture is inadequate. The section entitled ''Other Activities'' reveals continuing activities in new applications of nuclear techniques to problems in medicine and biology. Reactions important to astrophysics continue to be investigated and our trace-element program remains at a high level of activity. The theoretical section reports new progress in understanding magnitudes of two-step reactions by inclusion of finite-range effects. A new finite-range program which is fast and economical has been completed. Intermediate energy results include calculations of ..pi..-..gamma.. angular correlations, low energy ..pi..-nucleus interactions, as well as (p,d) and nucleon scattering calculations for intermediate energies.

  19. Cowden syndrome: Case report, update and proposed diagnostic and surveillance routines

    Directory of Open Access Journals (Sweden)

    Masuma Molvi

    2015-01-01

    Full Text Available Cowden syndrome (CS is an infrequent autosomal dominant multisystem genodermatosis, generally involving the skin, oral mucosa, thyroid, breast and gastrointestinal tract. It is characterized by a late onset in the 2 nd or 3 rd decade of life, an extraordinary potential for malignant transformation, especially of breast and thyroid, and an identifiable germline mutation. In 80% cases, the human tumor suppressor gene, phosphatase and tensin homolog (PTEN is mutated; mutations involving KILLIN, SDH B/D, PIK3CA and AKT1 genes account for the rest of the cases. Its clinical signs are not only the "essential pearls" for early and accurate diagnosis of CS but also help timely detection of neoplasia as they precede development of cancer by several years. We describe the first Indian and the third world report of polydactyly with CS, review this entity highlighting on recent clinical developments and emphasize on regular and thorough screening for prompt identification and management of the potentially malignant growths. We have also designed a baseline workup routine as well as a detailed screening program for these patients.

  20. A Self-Report Measure for the ICD-11 Dimensional Trait Model Proposal: The Personality Inventory for ICD-11.

    Science.gov (United States)

    Oltmanns, Joshua R; Widiger, Thomas A

    2017-02-23

    Proposed for the 11th edition of the World Health Organization's International Classification of Diseases (ICD-11) is a dimensional trait model for the classification of personality disorder (Tyrer, Reed, & Crawford, 2015). The ICD-11 proposal consists of 5 broad domains: negative affective, detachment, dissocial, disinhibition, and anankastic (Mulder, Horwood, Tyrer, Carter, & Joyce, 2016). Several field trials have examined this proposal, yet none has included a direct measure of the trait model. The purpose of the current study was to develop and provide initial validation for the Personality Inventory for ICD-11 (PiCD), a self-report measure of this proposed 5-domain maladaptive trait model. Item selection and scale construction proceeded through 3 initial data collections assessing potential item performance. Two subsequent studies were conducted for scale validation. In Study 1, the PiCD was evaluated in a sample of 259 MTurk participants (who were or had been receiving mental health treatment) with respect to 2 measures of general personality structure: The Eysenck Personality Questionnaire-Revised and the 5-Dimensional Personality Test. In Study 2, the PiCD was evaluated in an additional sample of 285 participants with respect to 2 measures of maladaptive personality traits: The Personality Inventory for DSM-5 and the Computerized Adaptive Test for Personality Disorders. Study 3 provides an item-level exploratory structural equation model with the combined samples from Studies 1 and 2. The results are discussed with respect to the validity of the measure and the potential benefits for future research in having a direct, self-report measure of the ICD-11 trait proposal.

    2015-01-01

    Background and purpose Outcome measurement has been shown to improve performance in several fields of healthcare. This understanding has driven a growing interest in value-based healthcare, where value is defined as outcomes achieved per money spent. While low back pain (LBP) constitutes an enormous burden of disease, no universal set of metrics has yet been accepted to measure and compare outcomes. Here, we aim to define such a set. Patients and methods An international group of 22 specialists in several disciplines of spine care was assembled to review literature and select LBP outcome metrics through a 6-round modified Delphi process. The scope of the outcome set was degenerative lumbar conditions. Results Patient-reported metrics include numerical pain scales, lumbar-related function using the Oswestry disability index, health-related quality of life using the EQ-5D-3L questionnaire, and questions assessing work status and analgesic use. Specific common and serious complications are included. Recommended follow-up intervals include 6, 12, and 24 months after initiating treatment, with optional follow-up at 3 months and 5 years. Metrics for risk stratification are selected based on pre-existing tools. Interpretation The outcome measures recommended here are structured around specific etiologies of LBP, span a patient’s entire cycle of care, and allow for risk adjustment. Thus, when implemented, this set can be expected to facilitate meaningful comparisons and ultimately provide a continuous feedback loop, enabling ongoing improvements in quality of care. Much work lies ahead in implementation, revision, and validation of this set, but it is an essential first step toward establishing a community of LBP providers focused on maximizing the value of the care we deliver.

    It is shown that, even in the presence of small attitude uncertainties, the gravitational gradient tensor actually has three independent invariants, instead of the two found by Sacerdote and Sanso (1989) and Holota (1988). It is also shown that the influence of angular rotation on gradiometric measurements can be eliminated by using the first differences of the measurement time series obtained. This also reauires the extraction of the angular acceleration rate from the sensor measurements. The adaptation of this technique to the planar sensor array proposed for Aristoteles is examined.

  5. Proposed criteria and indicators of ecosystem function for reclaimed oil sands sites : final report

    Sustainable forest management programs develop criteria and indicator (C and I) methodologies in order to demonstrate sustainability as well as to identify problems so that remedial actions can be employed. A critical feature of forestry-based C and I is the assumption that most of the basic ecosystem functions and services are in place at the time management activities are implemented. Application of the C and I approach to open-pit mining is often problematic, as the basic attributes of an ecosystem have been largely removed during mining operations. This report described a comprehensive list of indicators of forest ecosystem function along with a description of how they might be used to assess reclamation success in the oil sands region. Indicators were compiled from a workshop conducted at the University of British Columbia. The list was constrained by the fact that reclaimed oil sands sites are large and spatially heterogenous. The spatial and temporal nature of the data meant that sampling protocols were also necessary. Robust indicators that were economically expensive were favoured. Indicators were grouped under the following 3 criteria: (1) that the physical, chemical and biological properties of the soil are restored to target levels; (2) that the structure, composition and vigor of vegetation cover are restored to target levels; and (3) that critical ecosystem processes are restored to target levels. Criteria were selected to reflect the core attributes necessary for assessing development of a reclaimed ecosystem. Indicators included nitrogen-fixing symbionts; soil fauna; soil nutrients; mycorrhizae; snags; invasive species; wetland input water chemistry; foliar nutrition; nutrient budgets; and plant carbon allocation. It was noted that reference sites should be equivalent ecologically to their reclaimed analogue and located close to the restoration project, so that success in oil sands remediation projects can be evaluated by the rate at which a given

  6. A Characterization of Conserved Quantities in Non-Equilibrium Thermodynamics

    Directory of Open Access Journals (Sweden)

    Ignacio Romero

    2013-12-01

    Full Text Available The well-known Noether theorem in Lagrangian and Hamiltonian mechanics associates symmetries in the evolution equations of a mechanical system with conserved quantities. In this work, we extend this classical idea to problems of non-equilibrium thermodynamics formulated within the GENERIC (General Equations for Non-Equilibrium Reversible-Irreversible Coupling framework. The geometric meaning of symmetry is reviewed in this formal setting and then utilized to identify possible conserved quantities and the conditions that guarantee their strict conservation. Examples are provided that demonstrate the validity of the proposed definition in the context of finite and infinite dimensional thermoelastic problems.

  7. Covariant Hamiltonian boundary term: Reference and quasi-local quantities

    CERN Document Server

    Sun, Gang; Liu, Jian-Liang; Nester, James M

    2016-01-01

    The Hamiltonian for dynamic geometry generates the evolution of a spatial region along a vector field. It includes a boundary term which determines both the value of the Hamiltonian and the boundary conditions. The value gives the quasi-local quantities: energy-momentum, angular-momentum and center-of-mass. The boundary term depends not only on the dynamical variables but also on their reference values; the latter determine the ground state (having vanishing quasi-local quantities). For our preferred boundary term for Einstein's GR we propose 4D isometric matching and extremizing the energy to determine the reference metric and connection values.

    Full Text Available Once believed to be a human prerogative, the capacity to discriminate between quantities now has also been reported in several vertebrates. To date, only two studies investigated numerical abilities in horses (Equus caballus but reported contrasting data. To assess whether horses can be trained to discriminate between quantities, I have set up a new experimental protocol using operant conditioning. One adult female was trained to discriminate between 1 and 4 (Test 1 in three different conditions: non-controlled continuous variables (numerical and continuous quantities that co-vary with number are simultaneously available, 50% controlled continuous variables (intermediate condition, and 100% controlled continuous variables (only numerical information available. The subject learned the discrimination in all conditions, showing the capacity to process numerical information. When presented with a higher numerical ratio (2 vs. 4, Test 2, the subject still discriminated between the quantities but its performance was statistically significant only in the non-controlled condition, suggesting that the subject used multiple cues in presence of a more difficult discrimination. On the whole, the results here reported encourage the use of this experimental protocol as a valid tool to investigate the capacity to process numerical and continuous quantities in horses in future research.

    2014-05-01

    Full Text Available Purpose: Even without economic factors and government regulations, the pressure and motivation of corporation to reduce emission are still increasing. This is because the key factors for corporation to reduce emissions have become corporate social responsibility and identification of low-carbon value by consumer and society from economic trade-off and government regulations. So, the purpose of this paper is to provide quantity methods for the logistics organizations with wish of voluntary reduction and social responsibility.Design/methodology/approach: Being difference from the traditional research that takes economic value as object, this paper takes carbon footprint as object directly, order quantity as decision variable. By referring to the traditional economic order quantity model, the paper creates logistics carbon footprint model which takes transport and inventory into account. Then it solves the model by calculating the values of order quantity, carbon footprint and revenue using the method of optimization.Findings and Originality/value: By solving and comparing the two models of economic order quantity model and carbon footprint model, it gets some results, such as carbon optimization order quantity, the effects order quantity deviating from economic order quantity or carbon order quantity having on economic or carbon footprint values, which can give some meaningful insight for corporation to search out reduction opportunities by operations adjustment.Originality/value: The study takes carbon footprint as object directly and creates the corresponding quantity model. By comparing with the traditional economic order quantity model, the paper provides quantity methods and obtains some meaningful insights for the logistics organizations with wish of voluntary reduction and social responsibility to reduce emissions by operations adjustment.

    2012-01-01

    We develop an action principle for those models arising from isotropic loop quantum cosmology, and show that there is a natural conserved quantity $Q$ for the discrete difference equation arising from the Hamiltonian constraint. This quantity $Q$ relates the semi-classical limit of the wavefunction at large values of the spatial volume, but opposite triad orientations. Moreover, there is a similar quantity for generic difference equations of one parameter arising from a self-adjoint operator.

    2010-08-01

    A patient is presented with a cervical spinal cord transection which occurred after a motor vehicle accident in which the air bag deployed and the seat belt was not in use. The patient had complete quadriplegia below the C5 level and his imaging study showed cervical cord transection at the level of the C5/6 disc space with C5, C6 vertebral bodies and laminar fractures. He underwent a C5 laminectomy and a C4-7 posterior fusion with lateral mass screw fixation. Previous reports have described central cord syndromes occurring in hyperextension injuries, but in adults, acute spinal cord transections have only developed after fracture-dislocations of the spine. A case involving a post-traumatic spinal cord transection without any evidence of radiologic facet dislocations is reported. Also, we propose a combined hyperflexion-hyperextension mechanism to explain this type of injury.

    2009-07-01

    A public disclosure document was released for a proposed Dodds-RoundHill coal gasification project in January 2007, and the project was placed on hold in 2008 given some uncertainty around its future. However, there was a general sense that a project of this nature would be proposed for this coal-rich region at some point in the future. This report presented the results of a project completed by 14 graduate and undergraduate students in a social impact assessment course in 2009 at the University of Alberta. The purpose of the project was to learn specific concepts and methods for social impact assessment by undertaking such an assessment for the proposed Dodds-RoundHill coal gasification project, located southeast of Edmonton, Alberta. The 4 major components of a social impact assessment include scoping of relevant social indicators; social impacts within municipalities; social impacts within the farming region; and a comparative case study of social impacts. All of the research participants indicated that the project would have an impact on their community.

    We reported the preparation of colloidal graphene in quantity via the anodic exfoliation of graphite in (NH4)2SO4 aqueous solution. In the currently designed electrochemical exfoliation route, mass high-quality graphene was produced within short reaction time, around 1h. The proposed electrochemical exfoliation mechanism showed that SO4(2-) and H2O can be intercalated into those graphite sheets, monolayer and few-layer graphene were obtained by the formation of gaseous SO2 and O2 within graphite sheets. Stability evaluation showed that our exfoliated colloidal graphene can be perfectly stabilized in DMF solvent more than 1 week. The colloidal graphene can be used to construct various simple and complex patterns by writing it on A4 paper, which can be applied to flexible printed electronic devices. Furthermore, colloidal graphene can show promising applications in the fabrication of binder- and additive-free electrodes for supercapacitors and lithium-ion batteries. Our present method shows huge potential for industrial-scale synthesis of high-quality graphene and further commercialization of graphene colloid for numerous advanced applications in flexible printed electronics and energy storage devices.

  18. Processing ordinality and quantity: the case of developmental dyscalculia.

    Science.gov (United States)

    Rubinsten, Orly; Sury, Dana

    2011-01-01

    In contrast to quantity processing, up to date, the nature of ordinality has received little attention from researchers despite the fact that both quantity and ordinality are embodied in numerical information. Here we ask if there are two separate core systems that lie at the foundations of numerical cognition: (1) the traditionally and well accepted numerical magnitude system but also (2) core system for representing ordinal information. We report two novel experiments of ordinal processing that explored the relation between ordinal and numerical information processing in typically developing adults and adults with developmental dyscalculia (DD). Participants made "ordered" or "non-ordered" judgments about 3 groups of dots (non-symbolic numerical stimuli; in Experiment 1) and 3 numbers (symbolic task: Experiment 2). In contrast to previous findings and arguments about quantity deficit in DD participants, when quantity and ordinality are dissociated (as in the current tasks), DD participants exhibited a normal ratio effect in the non-symbolic ordinal task. They did not show, however, the ordinality effect. Ordinality effect in DD appeared only when area and density were randomized, but only in the descending direction. In the symbolic task, the ordinality effect was modulated by ratio and direction in both groups. These findings suggest that there might be two separate cognitive representations of ordinal and quantity information and that linguistic knowledge may facilitate estimation of ordinal information.

  20. Reporting the characteristics of the policy context for population-level alcohol interventions: a proposed 'Transparent Reporting of Alcohol Intervention ContExts' (TRAICE) checklist.

    2014-11-01

    Effectiveness of alcohol policy interventions varies across times and places. The circumstances under which effective polices can be successfully transferred between contexts are typically unexplored with little attention given to developing reporting requirements that would facilitate systematic investigation. Using purposive sampling and expert elicitation methods, we identified context-related factors impacting on the effectiveness of population-level alcohol policies. We then drew on previous characterisations of alcohol policy contexts and methodological-reporting checklists to design a new checklist for reporting contextual information in evaluation studies. Six context factor domains were identified: (i) baseline alcohol consumption, norms and harm rates; (ii) baseline affordability and availability; (iii) social, microeconomic and demographic contexts; (iv) macroeconomic context; (v) market context; and (vi) wider policy, political and media context. The checklist specifies information, typically available in national or international reports, to be reported in each domain. The checklist can facilitate evidence synthesis by providing: (i) a mechanism for systematic and more consistent reporting of contextual data for meta-regression and realist evaluations; (ii) information for policy-makers on differences between their context and contexts of evaluations; and (iii) an evidence base for adjusting prospective policy simulation models to account for policy context. Our proposed checklist provides a tool for gaining better understanding of the influence of policy context on intervention effectiveness. Further work is required to rationalise and aggregate checklists across interventions types to make such checklists practical for use by journals and to improve reporting of important qualitative contextual data. © 2014 The Authors.

    Many uncertainty propagation software exist, written in different programming languages, but not all of them are able to handle functional correlation between quantities. In this paper we review one strategy to deal with uncertainty propagation of quantities that are functionally correlated, and introduce a new software offering this feature: the Julia package Measurements.jl. It supports real and complex numbers with uncertainty, arbitrary-precision calculations, mathematical and linear algebra operations with matrices and arrays.

  4. Fuzzy Economic Order Quantity Inventory Models Without Backordering

    Institute of Scientific and Technical Information of China (English)

    WANG Xiaobin; TANG Wansheng; ZHAO Ruiqing

    2007-01-01

    In economic order quantity models without backordering, both the stock cost of each unit quantity and the order cost of each cycle are characterized as independent fuzzy variables rather than fuzzy numbers as in previous studies. Based on an expected value criterion or a credibility criterion, a fuzzy expected value model and a fuzzy dependent hance programming (DCP) model are constructed. The purpose of the fuzzy expected value model is to find the optimal order quantity such that the fuzzy expected value of the total cost is minimal. The fuzzy DCP model is used to find the optimal order quantity for maximizing the credibility of an event such that the total cost in the planning periods does not exceed a certain budget level.Fuzzy simulations are designed to calculate the expected value of the fuzzy objective function and the credibility of each fuzzy event. A particle swarm optimization (PSO) algorithm based on a fuzzy simulation is designed, by integrating the fuzzy simulation and the PSO algorithm. Finally, a numerical example is given to illustrate the feasibility and validity of the proposed algorithm.

  5. Inherently analog quantity representations in olive baboons (Papio anubis

    Directory of Open Access Journals (Sweden)

    Allison M Barnard

    2013-05-01

    Full Text Available Strong evidence indicates that non-human primates possess a numerical representation system, but the inherent nature of that system is still debated. Two cognitive mechanisms have been proposed to account for non-human primate numerical performance: (1 a discrete object-file system limited to quantities <4, and (2 an analog system which represents quantities comparatively but is limited by the ratio between two quantities. To test the underlying nature of non-human primate quantification, we asked eight experiment -naive olive baboons (Papio anubis to discriminate between number pairs containing small (<4, large (>4, or span (small vs. large numbers of food items presented simultaneously or sequentially. The prediction from the object-file hypothesis is that baboons will only accurately choose the larger quantity in small pairs, but not large or span pairs. Conversely, the analog system predicts that baboons will be successful with all numbers, and that success will be dependent on numerical ratio. We found that baboons successfully discriminated all pair types at above chance levels. In addition, performance significantly correlated with the ratio between the numerical values. Although performance was better for simultaneous trials than sequential trials, evidence favoring analog numerical representation emerged from both conditions, and was present even in the first exposure to number pairs. Together, these data favor the interpretation that a single, coherent analog representation system underlies spontaneous quantitative abilities in primates.

    This paper firstly evaluated the impedance method and traveling waves method for fault location, and studied the robustness of fault location method based on im-pedance. Then it proposed an assembled fault location method for a transmission line based on single-terminal electrical quantities, in which the fault zone was firstly determined by impedance method with robustness then the accurate fault position was pinpointed by traveling waves method. EMTP (Electromagnetic Transient Pro-gram) simulations showed that the proposed method can overcome the drawbacks of impedance method and traveling waves method when either one is used alone, and improve both the accuracy and the reliability of fault location.

  7. A shared system of representation governing quantity discrimination in canids

    Directory of Open Access Journals (Sweden)

    Joseph M Baker

    2012-10-01

    Full Text Available One way to investigate the evolution of cognition is to compare the abilities of phylogenetically related species. The domestic dog (Canis lupus familiaris, for example, still shares cognitive abilities with the coyote (C. latrans. Both of these canids possess the ability to make psychophysical less/more discriminations of food based on quantity. Like many other species including humans, this ability is mediated by Weber’s Law: discrimination of continuous quantities is dependent on the ratio between the two quantities. As two simultaneously presented quantities of food become more similar, choice of the large or small option becomes random in both dogs and coyotes. It remains unknown, however, whether these closely related species within the same family—one domesticated, and one wild—make such quantitative comparisons with comparable accuracy. Has domestication honed or diminished this quantitative ability? Might different selective and ecological pressures facing coyotes drive them to be more or less able to accurately represent and discriminate food quantity than domesticated dogs? This study is an effort to elucidate this question concerning the evolution of non-verbal quantitative cognition.Here, we tested the quantitative discrimination ability of 16 domesticated dogs. Each animal was given 9 trials in which two different quantities of food were simultaneously displayed to them. The domesticated dogs’ performance on this task was then compared directly to the data from 16 coyotes’ performance on this same task reported by Baker and colleagues (2011.The quantitative discrimination abilities between the two species were strikingly similar. Domesticated dogs demonstrated similar quantitative sensitivity as coyotes, suggesting that domestication may not have significantly altered the psychophysical discrimination abilities of canids. Instead, this study provides further evidence for similar nonverbal quantitative abilities across

    2011-12-01

    The experiences of 90 individuals who self-identify as "excessive" or "maladaptive" fantasizers are summarized in this report. Our sample consisted of 75 female and 15 male participants, ranging in age from 18 to 63 who responded to online announcements. Participants completed a 14-question emailed survey requesting descriptions of their fantasy habits and causes of potential distress regarding fantasy. Results demonstrated that participants shared a number of remarkably specific behaviors and concerns regarding their engagement in extensive periods of highly-structured, immersive imaginative experiences, including the use of kinesthetic activity which accompanies the fantasies of 79% of participants. Participants reported distress stemming from three factors: difficulty in controlling the need or desire to engage in fantasizing; concern that the quantity of fantasizing interfered with actual relationships and endeavors; and intense shame and exhaustive efforts to keep this behavior hidden from others. It is hoped that this report will encourage interest in this elusive syndrome.

  12. A generalized definition of dosimetric quantities.

    Science.gov (United States)

    Kellerer, A M; Rossi, H H

    1990-04-01

    The current definitions of microdosimetric and dosimetric quantities use the notion of 'ionizing radiation'. However, this notion is not rigorously defined, and its definition would require the somewhat arbitrary choice of specified energy cut-off values for different types of particles. Instead of choosing fixed cut-off values one can extend the system of definitions by admitting the free selection of a category of types and energies of particles that are taken to be part of the field. In this way one extends the system of dosimetric quantities. Kerma and absorbed dose appear then as special cases of a more general dosimetric quantity, and an analogue to kerma can be obtained for charged particle fields; it is termed cema. A modification that is suitable for electron fields is termed reduced cema.

    2004-01-01

    Some electromagnetic quantities in the black hole (BH) magnetosphere are discussed by considering the coexistence of the Blandford-Znajek process and the magnetic coupling process. These quantities are (i) flux of electromagnetic energy and angular momentum transferred between the BH and the disc, (ii) poloidal currents flowing on the horizon and disc, (iii) poloidal electric field on the horizon, (iv) toroidal magnetic field in the BH magnetosphere,and (v) voltage drop across the magnetic coupling region on the horizon. It turns out that these quantities are determined mainly by three parameters: (i) the positions relative to the corotation magnetic surface, (ii) the BH spin, and (iii) the power-law index for the variation of the magnetic field on the disc.

    Thin, solid bodies with metric symmetries admit a restricted form of reparameterization invariance. Their dynamical equilibria include motions with both rigid and flowing aspects. On such configurations, a quantity is conserved along the intrinsic coordinate corresponding to the symmetry. As an example of its utility, this conserved quantity is combined with linear and angular momentum currents to construct solutions for the equilibria of a rotating, flowing string, for which it is akin to Bernoulli's constant. - Highlights: • A conserved quantity relevant to the dynamical equilibria of thin structures. • A mixed Lagrangian–Eulerian non-material action principle for fixed windows of axially moving systems. • Analytical solutions for rotating, flowing strings (yarn balloons). • Noether meets Bernoulli in a textile factory.

    We present a new approach to find exact solutions for cosmological models. By requiring the existence of a symmetry transformation vector for the equations of motion of the given cosmological model (without using either Lagrangian or Hamiltonian), one can find corresponding Hojman conserved quantities. With the help of these conserved quantities, the analysis of the cosmological model can be simplified. In the case of quintessence scalar–tensor models, we show that the Hojman conserved quantities exist for a wide range of V(ϕ)-potentials and allow to find exact solutions for the cosmic scale factor and the scalar field. Finally, we investigate the general cosmological behavior of solutions by adopting a phase-space view.

  17. Likelihood estimations of vegetative alteration near known or proposed sources of air pollution. 1st annual progress report. [Computer simulation of effects on plants of SO/sub 2/ from fossil-fuel power plants sited in rural areas

    Energy Technology Data Exchange (ETDEWEB)

    Davis, D.D.; Pennypacker, S.P.

    1978-08-01

    There is an increasing trend to locate fossil-fuel electric generating stations in rural areas. These stations emit large quantities of air pollutants capable of causing serious alterations to the surrounding environment. The major phytotoxic air pollutant emitted is sulfur dioxide (SO/sub 2/). The best way to predict the potential impact of new or expanded sources in rural areas would be to develop a computer model to simulate and predict SO/sub 2/ injury to vegetation. The proposed simulator would provide valuable input information for tasks such as site selection and compilation of environmental impact statements. Such a model would also provide data to management operators for the regulation of emissions. The model would also aid in our basic understanding of the complex interactions which influence plant susceptibility to air pollution. Input to the model would consist of biological and physical data and the output would include the probability of SO/sub 2/ injuring vegetation near existing or proposed sites. The model would be validated using a field situation. This report presents the results obtained during the first year of the project (August 1, 1977 to July 31, 1978).

    Full Text Available The purpose of this study was to characterize factors affecting lactose quantities in raw cow's milk. This study combined the survey design with laboratory analysis. Selected farm members of Nong Poh Dairy Cooperatives, from Ban Pong and Photharam Districts, Ratchaburi Province, were sampled. From the selected farms, data collected included lactose quantities in the raw milk and dairy farming information. The raw milk of selected farms was sampled at the delivery site of Nong Poh dairy cooperatives in the morning during December 2003 till February 2004. Lactose in the raw milk was then quantified by the Fourier Transform Infrared Analysis (FTIR using the MilkoScan FT6000 at the Department of Livestock Development. The farm owners or managers of selected farms were in-depth interviewed on dairy farming information including cowsí health and cows' diet. The data revealed that all cows from the selected farms were fed with concentrate diet purchased from Nong Poh Dairy Cooperatives and grass as high fiber diets. Sample of eighteen farms also fed their cows with one of supplements: corn stem, soybean meal, or rice straw. All cows from these farms were Holstein-Friesian Hybrid. As supplemented high fiber diets, corn stem significantly increased the lactose quantities over soybean meal and rice straw (planned comparison, pvalue = 0.044. The study concluded that some high fiber diets, specifically corn stem, significantly contributed to the lactose quantities in raw milk.

  2. Quantity language speakers show enhanced subcortical processing.

    The complex auditory brainstem response (cABR) can reflect language-based plasticity in subcortical stages of auditory processing. It is sensitive to differences between language groups as well as stimulus properties, e.g. intensity or frequency. It is also sensitive to the synchronicity of the neural population stimulated by sound, which results in increased amplitude of wave V. Finnish is a full-fledged quantity language, in which word meaning is dependent upon duration of the vowels and consonants. Previous studies have shown that Finnish speakers have enhanced behavioural sound duration discrimination ability and larger cortical mismatch negativity (MMN) to duration change compared to German and French speakers. The next step is to find out whether these enhanced duration discrimination abilities of quantity language speakers originate at the brainstem level. Since German has a complementary quantity contrast which restricts the possible patterns of short and long vowels and consonants, the current experiment compared cABR between nonmusician Finnish and German native speakers using seven short complex stimuli. Finnish speakers had a larger cABR peak amplitude than German speakers, while the peak onset latency was only affected by stimulus intensity and spectral band. The results suggest that early cABR responses are better synchronised for Finns, which could underpin the enhanced duration sensitivity of quantity language speakers. Copyright © 2016 The Authors.

  12. Novel Ansatzes and Scalar Quantities in Gravito-Electromagnetism

    CERN Document Server

    Bakopoulos, Athanasios

    2016-01-01

    In this work, we focus on the theory of Gravito-Electromagnetism (GEM) -- the theory that describes the dynamics of the gravitational field in terms of quantities met in Electromagnetism -- and we propose two novel forms of metric perturbations. The first one is a generalisation of the traditional GEM ansatz, and succeeds in reproducing the whole set of Maxwell's equations even for a dynamical vector potential A. The second form, the so-called alternative ansatz, goes beyond that leading to an expression for the Lorentz force that matches the one of Electromagnetism and is free of additional terms even for a dynamical scalar potential \\Phi. In the context of the linearised theory, we then search for scalar invariant quantities in analogy to Electromagnetism. We define three novel, 3rd-rank gravitational tensors, and demonstrate that the last two can be employed to construct scalar quantities that succeed in giving results very similar to those found in Electromagnetism. Finally, the gauge invariance of the li...

    The U.S. Fish and Wildlife Service (FWS) is responsible for managing the Nation’s fish and wildlife resources so that these trust resources are preserved for the present and future use and enjoyment of the citizens of the United States. The FWS achieves this mission by managing many programs. These include the national system of refuges and fish hatcheries, Fish and Wildlife Management Assistance Offices, migratory birds program, law enforcement, and working with tribal, state, and other Federal agencies to ensure protection of threatened and endangered species. Another role of the FWS is consulting with tribal, state, and other Federal agencies and private sector interests on the best conservation management practices consistent with Federal law. Each of these activities requires a workforce that is recognized for its professionalism, dedication to public service, and command of expert knowledge. Recognition for expert knowledge in fish and wildlife conservation is demonstrated, in part, when FWS personnel direct, conduct, or report research that is well-designed to answer questions of importance for natural resource management. The data reported in this document are one part of a three-part study of the status of organizational support for research in FWS, which was commissioned by the Directorate of the FWS. Funding for this study was provided by the FWS, and the Science Support Program of the U.S. Geological Survey (USGS).

    We tested the relationship of objectively measured sleep quantity and quality with positive characteristics of the child. Sleep duration, sleep latency and sleep efficiency were measured by an actigraph for an average of seven (range = 3-14) consecutive nights in 291 8-year-old children (standard deviation = 0.3 years). Children's optimism, self-esteem and social competence were rated by parents and/or teachers. Sleep duration showed a non-linear, reverse J-shaped relationship with optimism (P = 0.02), such that children with sleep duration in the middle of the distribution scored higher in optimism compared with children who slept relatively little. Shorter sleep latency was related to higher optimism (P = 0.01). The associations remained when adjusting for child's age, sex, body mass index, and parental level of education and optimism. In conclusion, sufficient sleep quantity and good sleep quality are related to children's positive characteristics. Our findings may inform why sleep quantity and quality and positive characteristics are associated with wellbeing in children. © 2010 European Sleep Research Society.

  17. Quantity discrimination in wolves (Canis lupus

    Directory of Open Access Journals (Sweden)

    Ewelina eUtrata

    2012-11-01

    Full Text Available Quantity discrimination has been studied extensively in different non-human animal species. In the current study, we tested eleven hand-raised wolves (Canis lupus in a two-way choice task. We placed a number of food items (one to four sequentially into two opaque cans and asked the wolves to choose the larger amount. Moreover, we conducted two additional control conditions to rule out non-numerical properties of the presentation that the animals might have used to make the correct choice. Our results showed that wolves are able to make quantitative judgments at the group, but also at the individual level even when alternative strategies such as paying attention to the surface area or time and total amount are ruled out. In contrast to previous canine studies on dogs (Canis familiaris and coyotes (Canis latrans, our wolves’ performance did not improve with decreasing ratio, referred to as Weber’s law. However, further studies using larger quantities than we used in the current setup are still needed to determine whether and when wolves’ quantity discrimination conforms to Weber’s law.

  8. Maximizing Complementary Quantities by Projective Measurements

    M. Souza, Leonardo A.; Bernardes, Nadja K.; Rossi, Romeu

    2017-04-01

    In this work, we study the so-called quantitative complementarity quantities. We focus in the following physical situation: two qubits ( q A and q B ) are initially in a maximally entangled state. One of them ( q B ) interacts with a N-qubit system ( R). After the interaction, projective measurements are performed on each of the qubits of R, in a basis that is chosen after independent optimization procedures: maximization of the visibility, the concurrence, and the predictability. For a specific maximization procedure, we study in detail how each of the complementary quantities behave, conditioned on the intensity of the coupling between q B and the N qubits. We show that, if the coupling is sufficiently "strong," independent of the maximization procedure, the concurrence tends to decay quickly. Interestingly enough, the behavior of the concurrence in this model is similar to the entanglement dynamics of a two qubit system subjected to a thermal reservoir, despite that we consider finite N. However, the visibility shows a different behavior: its maximization is more efficient for stronger coupling constants. Moreover, we investigate how the distinguishability, or the information stored in different parts of the system, is distributed for different couplings.

  13. Effective dose: a radiation protection quantity

    CERN Document Server

    Menzel, H G

    2012-01-01

    Modern radiation protection is based on the principles of justification, limitation, and optimisation. Assessment of radiation risks for individuals or groups of individuals is, however, not a primary objective of radiological protection. The implementation of the principles of limitation and optimisation requires an appropriate quantification of radiation exposure. The International Commission on Radiological Protection (ICRP) has introduced effective dose as the principal radiological protection quantity to be used for setting and controlling dose limits for stochastic effects in the regulatory context, and for the practical implementation of the optimisation principle. Effective dose is the tissue weighted sum of radiation weighted organ and tissue doses of a reference person from exposure to external irradiations and internal emitters. The specific normalised values of tissue weighting factors are defined by ICRP for individual tissues, and used as an approximate age- and sex-averaged representation of th...

  14. Fluctuations of Intensive Quantities in Statistical Thermodynamics

    Directory of Open Access Journals (Sweden)

    Artur E. Ruuge

    2013-11-01

    Full Text Available In phenomenological thermodynamics, the canonical coordinates of a physical system split in pairs, with each pair consisting of an extensive quantity and an intensive one. In the present paper, the quasithermodynamic fluctuation theory of a model system of a large number of oscillators is extended to statistical thermodynamics based on the idea of perceiving the fluctuations of intensive variables as the fluctuations of specific extensive ones in a “thermodynamically dual” system. The extension is motivated by the symmetry of the problem in the context of an analogy with quantum mechanics, which is stated in terms of a generalized Pauli problem for the thermodynamic fluctuations. The doubled Boltzmann constant divided by the number of particles plays a similar role as the Planck constant.

  16. Nordic system for data and information exchange. Report from meetings with the authorities, and proposal for further work

    The EKO-4.2 project involves investigating approaches to setting up a new reliable system based on computer internet technology for exchange of information between the Nordic countries. According to the project plans this information exchange is to be based on bulletin board systems in the different countries. It was required that the system should not set any restriction of type of data or information to be exchanged, nor should it involve any standardization of data, and above all, it was not intended as an alert system. A bulletin board system is passive in the sense that no information is actually sent, instead it is the receiver who is responsible for approaching the information and transferring it to own system. This feature makes the system unsuitable for alert purposes. Since a potential system will have to be implemented by the authorities in the respective countries, the first part of the project was to survey their interest and emphasis. This was done in meetings in the different countries. The conclusion from those meetings was an overall interest in establishing a system as described, and several requirements concerning security and reliability of the system were proposed. The implication of the requirements by the authorities is discussed and a practical solution of an information exchange system based on the World Wide Web (WWW), the File Transfer Protocol (FTP), and the Internet is outlined. The continuation of the project must be based on operable servers in the different countries, whose configuration and connection with the local network are the responsibility of the institution owning the server. The selected system will depend on hardware and on the overall security policy of the institution involved. It is proposed that further work concentrates on a general testing of the system, standardizing of server user interfaces and testing of encryption software for transfer of passwords. (au)

  17. Evaluating the uncertainty of input quantities in measurement models

    Possolo, Antonio; Elster, Clemens

    2014-06-01

    The Guide to the Expression of Uncertainty in Measurement (GUM) gives guidance about how values and uncertainties should be assigned to the input quantities that appear in measurement models. This contribution offers a concrete proposal for how that guidance may be updated in light of the advances in the evaluation and expression of measurement uncertainty that were made in the course of the twenty years that have elapsed since the publication of the GUM, and also considering situations that the GUM does not yet contemplate. Our motivation is the ongoing conversation about a new edition of the GUM. While generally we favour a Bayesian approach to uncertainty evaluation, we also recognize the value that other approaches may bring to the problems considered here, and focus on methods for uncertainty evaluation and propagation that are widely applicable, including to cases that the GUM has not yet addressed. In addition to Bayesian methods, we discuss maximum-likelihood estimation, robust statistical methods, and measurement models where values of nominal properties play the same role that input quantities play in traditional models. We illustrate these general-purpose techniques in concrete examples, employing data sets that are realistic but that also are of conveniently small sizes. The supplementary material available online lists the R computer code that we have used to produce these examples (stacks.iop.org/Met/51/3/339/mmedia). Although we strive to stay close to clause 4 of the GUM, which addresses the evaluation of uncertainty for input quantities, we depart from it as we review the classes of measurement models that we believe are generally useful in contemporary measurement science. We also considerably expand and update the treatment that the GUM gives to Type B evaluations of uncertainty: reviewing the state-of-the-art, disciplined approach to the elicitation of expert knowledge, and its encapsulation in probability distributions that are usable in

  18. Classification and Clinical Management of Retrograde Peri-implantitis Associated with Apical Periodontitis: A Proposed Classification System and Case Report.

    Biological complications involving dental implants include peri-implant diseases such as peri-implant mucositis and peri-implantitis. The latter presents with progressive bone loss from the alveolar crest in a coronal apical direction. However, a separate disease entity termed retrograde peri-implantitis (RPI), which presents with progressive bone loss at the periapex of the implant, also exists and may be of particular interest to endodontists because it typically presents with periapical pathology of both the implant and adjacent tooth or at a site that previously housed an endodontically treated tooth. The reported prevalence of retrograde peri-implantitis is 0.26%, which is much lower than the prevalence of marginal peri-implantitis; however, its incidence increases to 7.8% when teeth adjacent to the implant exhibit an endodontic infection. It is positively correlated with a shorter distance between the implant and the adjacent tooth and a shorter time elapsed from the endodontically treated adjacent tooth to implant placement. This case report describes a patient diagnosed with an RPI lesion (RPI) associated with an adjacent endodontically treated tooth with a persistent periapical radiolucent lesion. The diagnosis, possible etiology, and management of the RPI lesion is thoroughly reported including follow-up visits showing complete resolution after subsequent periodontal and endodontic therapy. Endodontic evaluation of teeth adjacent to the implant site should be performed for primary prevention of RPI. Proper classification of RPI will aid in determining the course of treatment; class 1 and 2 cases require endodontic therapy of the involved teeth for healing to occur.

    Progress is reported on studies on hereditary anemias of mice. At present under study are four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, and the autoimmune hemolytic anemia of NZB. Each of these blood dyscrasias is caused by the action of a unique mutant gene, each of which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse.

  1. Facilitating the use of non-standard in vivo studies in health risk assessment of chemicals: a proposal to improve evaluation criteria and reporting.

    To improve data availability in health risk assessment of chemicals and fill information gaps there is a need to facilitate the use of non-standard toxicity studies, i.e. studies not conducted according to any standardized toxicity test guidelines. The purpose of this work was to propose criteria and guidance for the evaluation of reliability and relevance of non-standard in vivo studies, which could be used to facilitate systematic and transparent evaluation of such studies for health risk assessment. Another aim was to propose user friendly guidance for reporting of non-standard studies intended to promote an improvement in reporting of studies that could be of use in risk assessment. Requirements and recommendations for the design and execution of in vivo toxicity studies were identified from The Organisation for Economic Co-operation and Development (OECD) test guidelines, and served as basis for the data evaluation criteria and reporting guidelines. Feedback was also collected from experts within the field of toxicity testing and risk assessment and used to construct a two-tiered framework for study evaluation, as well as refine the reporting guidelines. The proposed framework emphasizes the importance of study relevance and an important aspect is to not completely dismiss studies from health risk assessment based on very strict criteria for reliability. The suggested reporting guidelines provide researchers with a tool to fulfill reporting requirements as stated by regulatory agencies. Together, these resources provide an approach to include all relevant data that may fill information gaps and reduce scientific uncertainty in health risk assessment conclusions, and subsequently also in chemical policy decisions.

  2. Conserved Quantities of harmonic asymptotic initial data sets

    2014-01-01

    In the first half of this article, we survey the new quasi-local and total angular momentum and center of mass defined in [9] and summarize the important properties of these definitions. To compute these conserved quantities involves solving a nonlinear PDE system (the optimal isometric embedding equation), which is rather difficult in general. We found a large family of initial data sets on which such a calculation can be carried out effectively. These are initial data sets of harmonic asymptotics, first proposed by Corvino and Schoen to solve the full vacuum constraint equation. In the second half of this article, the new total angular momentum and center of mass for these initial data sets are computed explicitly.

  3. Confidence and certainty: distinct probabilistic quantities for different goals

    Science.gov (United States)

    Pouget, Alexandre; Drugowitsch, Jan; Kepecs, Adam

    2017-01-01

    When facing uncertainty, adaptive behavioral strategies demand that the brain performs probabilistic computations. In this probabilistic framework, the notion of certainty and confidence would appear to be closely related, so much so that it is tempting to conclude that these two concepts are one and the same. We argue that there are computational reasons to distinguish between these two concepts. Specifically, we propose that confidence should be defined as the probability that a decision or a proposition, overt or covert, is correct given the evidence, a critical quantity in complex sequential decisions. We suggest that the term certainty should be reserved to refer to the encoding of all other probability distributions over sensory and cognitive variables. We also discuss strategies for studying the neural codes for confidence and certainty and argue that clear definitions of neural codes are essential to understanding the relative contributions of various cortical areas to decision making.

  5. Proposal of Unique Process Pump with Floating Type Centrifugal Impeller (Preliminarily Report : Axial Thrust of Impeller with Driving Shaft)

    2010-06-01

    The authors have proposed the unique centrifugal pump, in which the impeller dose not have the driving shaft but is driven by the magnetic induction, namely Lorentz force, without the stay. Then, the rotating posture of the impeller is not stable, just like UFO. To make the rotating posture of the impeller stable irrespective of the operating condition, the pressure in the impeller casing was investigated experimentally while the impeller rotates at the steady state, as the preliminarily stage. The pressure, as well known, fluctuates periodically in response to the blade number. Besides, the pressure on the impeller shrouds decreases with the increase of the gap between the front shroud and the suction cover where the water leaks to the suction pipe, and is distorted in the peripheral direction. Such pressure conditions contribute directly to the hydraulic force acting on the impeller. The unstable behaviors of the impeller are induced from the above hydraulic forces, which change unsteadily in the radial and the peripheral directions in the impeller casing. The forces are affected by not only the operating condition but also the rotating posture of the impeller.

    The objective of this study is to estimate the economic impact of the proposed Yakima/Klickitat Production Project on the local economies of the Yakima and Klickitat subbasins. The project, when operating at planned maximum production, will augment the total number of salmon and steelhead returning to the subbasins by 77,600 and will increase the sustainable terminal harvest by 55,160. These estimates do not include fish harvested in the ocean or in the mainstem Columbia. In addition to evaluating the impacts of the construction, operations and maintenance, experimentation and monitoring, and harvest activities described in the Draft Environmental Assessment (Bonneville Power Administration, 1989), our analysis also evaluates some passageway improvements and Phase II screening of irrigation structures. Both of these augmentations are required In order for the project to reach maximum planned harvest levels. The study area includes the Yakima Subbasin economy (Yakima and Kittitas counties), the mid-Columbia Basin/Klickitat Subbasin economies (Klickitat, Hood River, and Wasco counties), and the Tri-Cities economy (Benton and Franklin counties). The study period extends from 1990 through 2015: from preconstruction planning activities through reaching maximum production.

  10. How to introduce physical quantities physically

    Wagner, Serge A

    2015-01-01

    The centuries-long practice of the teaching turned mechanics into an academic construct detached from its underlying science, the physics of macroscopic bodies. In particular, the regularities that delineate the scope of validity of Newtonian mechanics was never used as premises in that construct. Instead, its logical structure has been built with the only purpose to ease the presentation of mechanics as an application of calculus and algebra. This leaves no room for the explicit physical description of the fundamental notions of the construct, such as the ability of (a system of) physical bodies to keep a spatial form, symbolized by a rigid measuring rod, and the possibility to count out even temporal intervals, symbolized by a standard clock, let alone the origin of the basic mechanical quantities. The comparison between (states of) physical objects is possible as far as the natural regularities enable a researcher to define an equivalence relation in a set of these objects. The class of macroscopic (or mac...

    2016-04-01

    We discuss the application of the Hojman's Symmetry Approach for the determination of conservation laws in Cosmology, which has been recently applied by various authors in different cosmological models. We show that Hojman's method for regular Hamiltonian systems, where the Hamiltonian function is one of the involved equations of the system, is equivalent to the application of Noether's Theorem for generalized transformations. That means that for minimally-coupled scalar field cosmology or other modified theories which are conformally related with scalar-field cosmology, like f (R) gravity, the application of Hojman's method provide us with the same results with that of Noether's Theorem. Moreover we study the special Ansatz. ϕ (t) = ϕ (a (t)) , which has been introduced for a minimally-coupled scalar field, and we study the Lie and Noether point symmetries for the reduced equation. We show that under this Ansatz, the unknown function of the model cannot be constrained by the requirement of the existence of a conservation law and that the Hojman conservation quantity which arises for the reduced equation is nothing more than the functional form of Noetherian conservation laws for the free particle. On the other hand, for f (T) teleparallel gravity, it is not the existence of Hojman's conservation laws which provide us with the special function form of f (T) functions, but the requirement that the reduced second-order differential equation admits a Jacobi Last multiplier, while the new conservation law is nothing else that the Hamiltonian function of the reduced equation.

    The exponential growth in scientific journals and advent of the electronic era have led to such information overload that the sustainability of credible and quality publications is more urgent than ever. Editors and academics who commit themselves to nurturing young writers need to reaffirm their focus on quality rather than quantity of papers. Bearing in mind that publications should firstly be founded on good science, there are several approaches in helping the uninitiated develop and hone writing skills. Academic journals faithfully publish instructions to guide potential authors on the preparation and submission of manuscripts. For those with a gift for writing, this may suffice to start them soaring in their writing career. Others find the hands-on approach of writing workshops more effective in clarifying the rules of the writing game and dispelling the fear of writing. Workshops are good at demonstrating the basics, but the forging of a good writer is a long process in which a mentor can play an invaluable role. A nurturing mentor-mentee relationship should not be a stifling one, but one that leads, grows and finally liberates an independent writer. It is inevitable that the nature of scientific publications will change over time. Nonetheless, the sustainability of quality journals will remain linked to the continual generation of writers who uphold scientific truth and good writing values.

    Full Text Available The activation response of a material is a primary factor considered when evaluating its suitability for a nuclear application. Various radiological quantities, such as total (becquerel activity, decay heat, and γ dose, can be readily predicted via inventory simulations, which numerically evolve in time the composition of a material under exposure to neutron irradiation. However, the resulting data sets can be very complex, often necessarily resulting in an over-simplification of the results – most commonly by just considering total response metrics. A number of different techniques for disseminating more completely the vast amount of data output from, in particular, the FISPACT-II inventory code system, including importance diagrams, nuclide maps, and primary knock-on atom (PKA spectra, have been developed and used in scoping studies to produce database reports for the periodic table of elements. This paper introduces the latest addition to this arsenal – standardised and automated plotting of the time evolution in a radiological quantity for a given material separated by contributions from dominant radionuclides. Examples for relevant materials under predicted fusion reactor conditions, and for bench-marking studies against decay-heat measurements, demonstrate the usefulness and power of these radionuclide-separated activation plots.

    2005-01-01

    The relationship between public health and improper collection, handling, and disposal of solid wastes in general, and hospital wastes in particular, is quite clear. Hazardous and nonhazardous wastes generated from different divisions of two of the largest public hospitals (capacity of approximately 400 beds each) in Kuwait were quantified and generation rates were determined. The generation rates were related to some important factors such as the number of patients, number of beds, and the type of activity conducted in different sections of the hospitals. The relationship between the waste generation rate and the number of patients was more applicable than that expressed in terms of the number of beds. The rates observed were in the range of 4.89 to 5.4 kg/patient/day, which corresponds to 3.65 to 3.97 kg/bed/day, respectively. These generation rates were comparable with those reported in the literature for similar hospitals. Minimal waste quantities were collected in the weekends. The study indicated that the hospitals surveyed provide some segregation of hazardous and nonhazardous wastes. Hazardous wastes contributed about 53% of the total quantity of wastes generated at the hospitals.

    Full Text Available Abstract Background Research on cannabis use has emphasized frequency as a predictor of problems. Studies of other drugs reveal that frequency relates to psychological and physiological outcomes, but quantity also plays an important role. In the study of cannabis, quantity has been difficult to assess due to the wide range of products and means of consumption. Methods The present study introduces three new measures of quantity, and examines their contribution to cannabis-related problems. Over 5,900 adults using cannabis once or more per month completed an internet survey that inquired about use, dependence, social problems and respiratory health. In addition to detailing their frequency of cannabis use, participants also reported three measures of quantity: number of quarter ounces consumed per month, usual intensity of intoxication, and maximum intensity of intoxication. Results Frequency of use, monthly consumption, and levels of intoxication predicted respiratory symptoms, social problems and dependence. What is more, each measure of quantity accounted for significant variance in outcomes after controlling for the effects of frequency. Conclusion These findings indicate that quantity is an important predictor of cannabis-related outcomes, and that the three quantity measures convey useful information about use.

    2012-12-01

    Full Text Available Background Avascular Necrosis (AVN is defined as the cellular death of bone components due to an alteration of the blood supply, resulting in Edema of the Bone Marrow (BME, structural collapse and bone destruction. In advanced stages, AVN requires surgery. One emerging medical treatment for supporting osseous perfusion is the administration of iloprost.Materials and methods A 38-year-old woman presented with severe BME of the left hip (primary, persisting for 6 weeks. She was treated with iloprost iv at 2 ng/kg/min for 6 hours/day for 5 days, and after 4 weeks, the treatment was repeated at 1.5 ng/kg/min for 6 hours for 5 days because she exhibited only a partial response to the first treatment. Complete remission was obtained, documented clinically and on Magnetic Resonance Imaging (MRI. Her Harris Hip Score (HHS increased from 29.90 to 97. No significant adverse events related to iloprost were registered. No surgical procedures were necessary.Conclusions In most cases, iloprost is administered in a single cycle of treatment over 5 days at 1-2 ng/kg/min for 6 hours/day, but no research has investigated the effectiveness of early retreatment after the first cycle results in only a partially response. Only a few studies examining small numbers of patients have evaluated iloprost in AVN/BME, preferring, in most cases, the dose of 1 ng/kg/min and obtaining clinical improvement both in BME and in AVN in times comparable to surgical core decompression. This case report demonstrates the safety and effectiveness of early repetition of the maximal dose of iloprost before BME evolves into AVN, as well as in cases initially appearing serious and requiring surgical procedures.

    Sloshing causes liquid to fluctuate, making accurate level readings difficult to obtain in dynamic environments. The measurement system described uses a single-tube capacitive sensor to obtain an instantaneous level reading of the fluid surface, thereby accurately determining the fluid quantity in the presence of slosh. A neural network based classification technique has been applied to predict the actual quantity of the fluid contained in a tank under sloshing conditions.   In A neural network approach to fluid quantity measurement in dynamic environments, effects of temperature variations and contamination on the capacitive sensor are discussed, and the authors propose that these effects can also be eliminated with the proposed neural network based classification system. To examine the performance of the classification system, many field trials were carried out on a running vehicle at various tank volume levels that range from 5 L to 50 L. The effectiveness of signal enhancement on the neural network base...

Precipitation in the area averages about 14 inches per year, of which about 10 inches fall during the April-September irrigation season. Projected water requirements at the plant site are 6020 acre-feet per year. Since the proposed plant site is not near any major streams or rivers, water must be transported to it. Water will be supplied from four sources - two surface water and two groundwater. The two surface water sources are LaPrele Reservoir and flood flows from the North Platte River with a 1974 appropriations date. LaPrele Reservoir is located approximately 14 miles west of Douglas, Wyoming, and is shown on Figure A-1. Water will be released from LaPrele Reservoir and flow down LaPrele Creek to the North Platte River. Water from the North Platte River will be diverted at a point in Section 7 of T33N, R71W. The LaPrele water and excess water from the North Platte will be pumped from the river and stored in Panhandle Reservoir No. 1, which is also referred to as Combs Reservoir. A pipeline will convey water from Panhandle Reservoir No. 1 to the coal gasification plant site. The two groundwater sources are located north of Douglas and west of Douglas.

  4. On the applicability of the principle of the quantity-to-quality transition to chemical evolution that led to life

    We review and re-examine the arguments for the proposal that life emerged by a quantity-to-quality transition of abiotic matter. This idea was originally proposed by the dialectical materialists, who are the proponents of the materialistic approach to Hegel's laws of dialectics. We find that one of the universal features of the quantity-to-quality transitions is the change in the organization of the system, which brings about novelty. We suggest that the principle of the quantity-to-quality transition may be a part of the algorithm of life, which is not Earth-centric.

  5. On the Hojman conservation quantities in Cosmology

    Full Text Available We discuss the application of the Hojman's Symmetry Approach for the determination of conservation laws in Cosmology, which has been recently applied by various authors in different cosmological models. We show that Hojman's method for regular Hamiltonian systems, where the Hamiltonian function is one of the involved equations of the system, is equivalent to the application of Noether's Theorem for generalized transformations. That means that for minimally-coupled scalar field cosmology or other modified theories which are conformally related with scalar-field cosmology, like f(R gravity, the application of Hojman's method provide us with the same results with that of Noether's Theorem. Moreover we study the special Ansatz. ϕ(t=ϕ(a(t, which has been introduced for a minimally-coupled scalar field, and we study the Lie and Noether point symmetries for the reduced equation. We show that under this Ansatz, the unknown function of the model cannot be constrained by the requirement of the existence of a conservation law and that the Hojman conservation quantity which arises for the reduced equation is nothing more than the functional form of Noetherian conservation laws for the free particle. On the other hand, for f(T teleparallel gravity, it is not the existence of Hojman's conservation laws which provide us with the special function form of f(T functions, but the requirement that the reduced second-order differential equation admits a Jacobi Last multiplier, while the new conservation law is nothing else that the Hamiltonian function of the reduced equation.

  6. Gastrointestinal stromal tumors (GIST) from risk stratification systems to the new TNM proposal: more questions than answers? A review emphasizing the need for a standardized GIST reporting

    Science.gov (United States)

    Agaimy, Abbas

    2010-01-01

    Following the successful introduction of the receptor tyrosine kinase inhibitors (TKI) as the mainstay for the treatment of advanced and metastatic gastrointestinal stromal tumor (GIST), GIST has received a special attention in the recent literature. This resulted in major achievements on the surgical pathology diagnosis and improved our understanding of the molecular biology of the disease. Availability of the effective TKI therapy has emphasized the need for a more reliable and reproducible system for assessment of the malignant potential in GIST to allow for an optimal individualized patient treatment. All of the risk stratification systems proposed so far have emphasized the value of tumor size, mitotic count and anatomic site for risk estimation, at the same time appreciating the difficulty of classifying individual tumors as either benign or malignant. The newly proposed UICC TNM classification for GISTs represents the most recent hallmark on this topic; yet its usefulness remains to be tested in future clinical studies. This review briefly summarizes and discusses the most pertinent risk systems proposed for assessment of the malignant potential of GIST stressing their advantages and limitations and including some critical remarks on the newly proposed UICC TNM system for classifying GIST. Most importantly, an emphasis is made on the urgent need for a standardized approach for histopathological evaluation and reporting of GIST specimens to allow for a reproducible tumor size, mitotic count and tumor growth pattern, and hence for a better risk classification.

    2016-07-01

    Recently, there has been much progress in understanding the thermodynamics of quantum systems, even for small individual systems. Most of this work has focused on the standard case where energy is the only conserved quantity. Here we consider a generalization of this work to deal with multiple conserved quantities. Each conserved quantity, which, importantly, need not commute with the rest, can be extracted and stored in its own battery. Unlike the standard case, in which the amount of extractable energy is constrained, here there is no limit on how much of any individual conserved quantity can be extracted. However, other conserved quantities must be supplied, and the second law constrains the combination of extractable quantities and the trade-offs between them. We present explicit protocols that allow us to perform arbitrarily good trade-offs and extract arbitrarily good combinations of conserved quantities from individual quantum systems.

    One aim of the workshop was to support and provide an ICRU report committee (International Union of Radiation Units) with actual information on techniques, data and knowledge of modern radioecology when radionuclides are to be measured in the environment. It has been increasingly recognised that some studies in radioecology, especially those involving both field sampling and laboratory measurements, have not paid adequate attention to the problem of obtaining representative, unbiased samples. This can greatly affect the quality of scientific interpretation, and the ability to manage the environment. Further, as the discipline of radioecology has developed, it has seen a growth in the numbers of quantities and units used, some of which are ill-defined and which are non-standardised. (orig.)

    Objective: to propose a model to standardize computed tomography reports on abdominal aortic aneurysms. Materials and methods: interviews were carried out with members of the Vascular Surgery Division of our institution, in the period between April and October 2004, aiming at developing a standardized model of computed tomography reports on abdominal aortic aneurysms. Based on this model, a questionnaire was elaborated and sent to other nine surgeons, all of them experienced in the field of abdominal aortic surgery. The questionnaires response rate was 55.5% (5/9). Results: the most frequently mentioned parameters of interest for evaluation of abdominal aortic aneurysms were: maximum diameter of proximal aortic neck, proximal aortic neck length to lower renal arteries, shape of proximal aortic neck, maximum diameter of the aneurysm and diameter of the common iliac arteries. These data allowed the development of a proposal for a model to standardize computed tomography reports. Conclusion: a model for standardized tomographic analysis of abdominal aortic aneurysms has met vascular surgeons' needs for following-up patients and planning their treatment. (author)

  10. Preliminary draft industrial siting administration permit application: Socioeconomic factors technical report. Final technical report, November 1980-May 1982. [Proposed WyCoalGas project in Converse County, Wyoming

    Energy Technology Data Exchange (ETDEWEB)

    1982-01-01

    Under the with-project scenario, WyCoalGas is projected to make a difference in the long-range future of Converse County. Because of the size of the proposed construction and operations work forces, the projected changes in employment, income, labor force, and population will alter Converse County's economic role in the region. Specifically, as growth occurs, Converse County will begin to satisfy a larger portion of its own higher-ordered demands, those that are currently being satisfied by the economy of Casper. Business-serving and household-serving activities, currently absent, will find the larger income and population base forecast to occur with the WyCoalGas project desirable. Converse County's economy will begin to mature, moving away from strict dependence on extractive industries to a more sophisticated structure that could eventually appeal to national, and certainly, regional markets. The technical demand of the WyCoalGas plant will mean a significant influx of varying occupations and skills. The creation of basic manufacturing, advanced trade and service sectors, and concomitant finance and transportation firms will make Converse County more economically autonomous. The county will also begin to serve market center functions for the smaller counties of eastern Wyoming that currently rely on Casper, Cheyenne or other distant market centers. The projected conditions expected to exist in the absence of the WyCoalGas project, the socioeconomic conditions that would accompany the project, and the differences between the two scenarios are considered. The analysis is keyed to the linkages between Converse County and Natrona County.

  11. Estimated quantities of residual materials in a KBS-3H repository at Olkiluoto

    The quantities of residual materials in a KBS-3H type repository have been estimated in this report. The repository is assumed to be constructed at Olkiluoto in Eurajoki, Western Finland. Both the total quantities of the materials introduced into the repository and the quantities of materials that remain in the repository after closure have been calculated. The calculations are largely based on a similar work regarding the material quantities in the Finnish KBS-3V repository and the main goal has been to identify the differences between the KBS-3H and KBS-3V repositories with respect to the type and quantities of residual materials. As the design of the KBS-3H repository is not final yet, the results are only preliminary. Several alternative designs were assumed in the calculations, resulting in different total quantities of materials. The design alternatives that had the greatest effect on the total material quantities were the two different tunnel backfill options, bentonite-crushed rock and Friedland clay. If Friedland clay is used instead of a bentonite-crushed rock mixture, the total quantity of pyrite remaining in the repository is 20 times larger and the quantities of organic materials and gypsum are also increased significantly. The other design alternatives did not have a substantial effect on the total material quantities. The remaining quantity of cement can be reduced by some 20% by selecting the silica grouting alternative in the sealing of the rock mass and low-pH cement in the shotcreting of the repository, instead of using the ordinary cement alternatives. If the total quantity of steel should be minimised, the use of the DAWE design alternative would be better than the Basic Design, although the total reduction would be less than 10%. The main difference between the different drift end plug alternatives is related to the total remaining quantity of silica, which is some 80% smaller if the rock plug is used instead of the LHHP (Low Heat High

  12. Maximizing DNA profiling success from sub-optimal quantities of DNA: a staged approach.

    Roeder, Amy D; Elsmore, Paul; Greenhalgh, Matt; McDonald, Andrew

    2009-03-01

    Obtaining genetic profiles from samples containing minimal amounts of DNA can be difficult. In forensic science, the vast majority of genetic profiles are generated using commercial kits that have been optimized for the amplification of a specific range of DNA concentrations. DNA extracted from many forensic samples falls below the kit manufacturers' specified concentrations either because there is not enough total DNA in the extract or the extract is so dilute that not enough volume of the extract can be added to the PCR. In order to develop a method to maximize SGM Plus and Identifiler profiling success from samples with sub-optimal quantities of DNA, thermocycle numbers and/or the amount of PCR product injected during capillary electrophoresis (termed Enhancement) of PCR products were increased. Increasing the number of thermocycles from 28 to 30 and/or two phases of Enhancement of both 28 and 30 thermocycle PCR products resulted in an increased number of scorable peaks. As expected with low template amounts of DNA, many of the samples showed allelic drop-out, heterozygote imbalances and sporadic, large stutter peaks. Enhancement decreased the amount of allelic drop-out observed and did not affect stutter peak or heterozygous peak height ratios. Although the PCR reactions from these samples should always be replicated before a reportable consensus profile is reached, Phase 1 and 2 Enhancement can maximize the profiling success from each reaction. Finally, a flexible, staged approach using 28 or 30 thermocycle PCR in combination with the Enhancement techniques described here is proposed for processing samples with sub-optimal quantities of DNA.

  13. Torsor Theory of Physical Quantities and their Measurement

    Directory of Open Access Journals (Sweden)

    Domotor Zoltan

    2017-08-01

    Full Text Available The principal objective of this paper is to provide a torsor theory of physical quantities and basic operations thereon. Torsors are introduced in a bottom-up fashion as actions of scale transformation groups on spaces of unitized quantities. In contrast, the shortcomings of other accounts of quantities that proceed in a top-down axiomatic manner are also discussed. In this paper, quantities are presented as dual counterparts of physical states. States serve as truth-makers of metrological statements about quantity values and are crucial in specifying alternative measurement units for base quantities. For illustration and ease of presentation, the classical notions of length, time, and instantaneous velocity are used as primordial examples. It is shown how torsors provide an effective description of the structure of quantities, systems of quantities, and transformations between them. Using the torsor framework, time-dependent quantities and their unitized derivatives are also investigated. Lastly, the torsor apparatus is applied to deterministic measurement of quantities.

    Social-medical expert reports from the German statutory pension insurance are essential for the German statutory pension regulatory authority to decide whether to grant services regarding participation as well as retirement pensions due to incapacity to work.The objective of this investigation is to determine whether the ICF Core Sets and other international approaches, such as the EUMASS Core Sets or ICF Core Set for vocational rehabilitation cover the content of the social-medical expert reports as well as to propose an approach how the ICF can be economically used by the social medicine practitioner when writing a social-medical expert report. A retrospective quantitative study design was used to translate a total of 294 social-medical expert reports from patients with low back pain (LBP) or chronic widespread pain (CWP) into the language of the ICF (linking) by 2 independent health professionals and compare the results with the ICF Core Sets for specific health conditions and other international approaches. The content of social-medical expert reports was largely reflected by the condition specific brief ICF Core Sets, brief ICF Core Sets for vocational rehabilitation and EUMASS Core Sets. The weighted Kappa statistic for the agreement between the 2 health professionals who translated the expert reports were in CWP 0.69 with a bootstrapped confidence interval of 0.67-0.71 and in LBP 0.73 (0.71-0.74). The analyses show that the content of social-medical expert reports varies enormously. A combination of a condition specific brief ICF Core Set as well as vocational rehabilitation and EUMASS ICF Core Sets as well as all ICF-categories from the expert reports that were named at least in 50% of it can largely provide a basis for preparing expert reports. Within the scope of implementation the need for a specific ICF Core Set for expert reports of the German statutory pension insurance should be further analyzed and discussed. © Georg Thieme Verlag KG Stuttgart

    de Boer, J.

    1995-01-01

    A brief presentation is given of the most important developments in the history of quantity calculus. Starting with the early introduction of the concept "physical quantity" by Maxwell in his work on electricity and magnetism, attention is focused in particular on the foundations of the calculus with physical quantities given by Wallot in the 1920s. For illustration and better understanding of the praxis of quantity calculus, special attention is paid to the three- and four-dimensional systems of physical quantities used for theoretical description in the fields of electricity and magnetism. Special emphasis is placed on understanding controversies and confusion caused by differences in interpretation of the concepts "quantity" and "unit" in physical language and in the mathematical description of physical phenomena. A short presentation is given of the further development of various studies on the algebraic structure and the axiomatic foundation of the calculus with physical quantities developed by Landolt, Stille, Fleischmann and others. Quantity calculus constituted the basis for obtaining consensus on the introduction of the International System of Units (SI) and allowed the formulation of international standards on definitions and symbols for quantities and units by the various international scientific and standardizing organizations.

    2007-01-01

    Quantity discount scheme plays an important role in supply chain management. The different quantity discount schemes under symmetric (full) information and asymmetric information, are analyzed by using principal-agent and optimal control theory. As a result, the research reveals that the optimal quantity discount solution under symmetric information is a special case of that under asymmetric information. At the same price, the critical value of quantity discount under asymmetric information is much lower than that under asymmetric information. Therefore, this leads to less cost for retailers and smaller profit for their supplier.

    2001-01-01

    Full Text Available In this article the quantity of cholesterol in butter - a representative of dairy products with known high quantity of milk fat, is determined. The results show that the quantity of milk fats for the butter samples from domestic production (n=17 was 83.9 %, and from the industrial production (n=5 85.2 %. Average cholesterol quantities, in before mentioned samples, were 227 mg/100g or 22 mg of cholesterol per 100 g of sample. The results show that the increase of milk fats does not strictly influence cholesterol increase in the individual butter sample.

    This study examines whether energy drink use and binge drinking predict sleep quantity, sleep quality, and next-day tiredness among college students. Web-based daily data on substance use and sleep were collected across four semesters in 2009 and 2010 from 667 individuals for up to 56 days each, yielding information on 25,616 person-days. Controlling for average levels of energy drink use and binge drinking (i.e., 4+ drinks for women, 5+ drinks for men), on days when students consumed energy drinks, they reported lower sleep quantity and quality that night, and greater next-day tiredness, compared to days they did not use energy drinks. Similarly, on days when students binge drank, they reported lower sleep quantity and quality that night, and greater next-day tiredness, compared to days they did not binge drink. There was no significant interaction effect between binge drinking and energy drink use on the outcomes.

    Yin, Sisi; Nishi, Tatsushi

    2014-11-01

    Quantity discount policy is decision-making for trade-off prices between suppliers and manufacturers while production is changeable due to demand fluctuations in a real market. In this paper, quantity discount models which consider selection of contract suppliers, production quantity and inventory simultaneously are addressed. The supply chain planning problem with quantity discounts under demand uncertainty is formulated as a mixed-integer nonlinear programming problem (MINLP) with integral terms. We apply an outer-approximation method to solve MINLP problems. In order to improve the efficiency of the proposed method, the problem is reformulated as a stochastic model replacing the integral terms by using a normalisation technique. We present numerical examples to demonstrate the efficiency of the proposed method.

    2015-05-01

    Full Text Available While the quantity of water used in the home is thought to be an important determinant of health, much of the evidence relies on using water access as a proxy for quantity. This review examines the health effects of household water quantity using studies that directly measured water quantity. We searched MEDLINE, EMBASE, the Cochrane Library, Web of Science, and article reference lists. Eligible studies included experimental and observational studies that measured a difference in water quantity and quantified an association between water quantity and health outcomes. 21 studies, divided into six of the many possible water-quantity associated outcomes, met the eligibility criteria. Due to heterogeneity in designs, settings, methods, and outcomes, a meta-analysis was inappropriate. Overall results showed a positive association between water quantity and health outcomes, but the effect depended on how the water was used. Increased water usage for personal hygiene was generally associated with improved trachoma outcomes, while increased water consumption was generally associated with reduced gastrointestinal infection and diarrheal disease and improved growth outcomes. In high-income countries, increased water consumption was associated with higher rates of renal cell carcinoma and bladder cancer but not associated with type II diabetes, cardiac-related mortality, or all-cause mortality.

Due to heterogeneity in designs, settings, methods, and outcomes, a meta-analysis was inappropriate. Overall results showed a positive association between water quantity and health outcomes, but the effect depended on how the water was used. Increased water usage for personal hygiene was generally associated with improved trachoma outcomes, while increased water consumption was generally associated with reduced gastrointestinal infection and diarrheal disease and improved growth outcomes. In high-income countries, increased water consumption was associated with higher rates of renal cell carcinoma and bladder cancer but not associated with type II diabetes, cardiac-related mortality, or all-cause mortality.

    The proposed work covers a broad range of topics in theoretical nuclear and intermediate-energy physics and in nuclear astrophysics. With free nucleon--nucleon interactions as a basis, effective forces in nuclei are constructed through a chain of field-theoretic, dispersions and many-body techniques. Dynamical theories of nuclear excitations are constructed. Infinite nuclear systems at a variety of densities are studied in order to determine reliable equations of state for nuclear and neutron matter. These equations of state are applied in astrophysical problems, such as the gravitational collapse of stars, as well as in standard nuclear contexts. Brief summaries of individual projects completed and planned are given. Completed research is reported in the appropriate places.

    Full Text Available In this paper, a multi products single machine economic order quantity model with discrete delivery is developed. A unique cycle length is considered for all produced items with an assumption that all products are manufactured on a single machine with a limited capacity. The proposed model considers different items such as production, setup, holding, and transportation costs. The resulted model is formulated as a mixed integer nonlinear programming model. Harmony search algorithm, extended cutting plane and particle swarm optimization methods are used to solve the proposed model. Two numerical examples are used to analyze and to evaluate the performance of the proposed model.

  19. Introductory lecture: basic quantities in model biomembranes.

    2013-01-01

    One of the many aspects of membrane biophysics dealt with in this Faraday Discussion regards the material moduli that describe energies at a supramolecular level. This introductory lecture first critically reviews differences in reported numerical values of the bending modulus K(C), which is a central property for the biologically important flexibility of membranes. It is speculated that there may be a reason that the shape analysis method tends to give larger values of K(C) than the micromechanical manipulation method or the more recent X-ray method that agree very well with each other. Another theme of membrane biophysics is the use of simulations to provide exquisite detail of structures and processes. This lecture critically reviews the application of atomic level simulations to the quantitative structure of simple single component lipid bilayers and diagnostics are introduced to evaluate simulations. Another theme of this Faraday Discussion was lateral heterogeneity in biomembranes with many different lipids. Coarse grained simulations and analytical theories promise to synergistically enhance experimental studies when their interaction parameters are tuned to agree with experimental data, such as the slopes of experimental tie lines in ternary phase diagrams. Finally, attention is called to contributions that add relevant biological molecules to bilayers and to contributions that study the exciting shape changes and different non-bilayer structures with different lipids.

  20. An Adaptive Information Quantity-Based Broadcast Protocol for Safety Services in VANET

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Vehicle-to-vehicle communication plays a significantly important role in implementing safe and efficient road traffic. When disseminating safety messages in the network, the information quantity on safety packets changes over time and space. However, most of existing protocols view each packet the same to disseminate, preventing vehicles from collecting more recent and precise safety information. Hence, an information quantity-based broadcast protocol is proposed in this paper to ensure the efficiency of safety messages dissemination. In particular, we propose the concept of emergency-degree to evaluate packets’ information quantity. Then we present EDCast, an emergency-degree-based broadcast protocol. EDCast differentiates each packet’s priority for accessing the channel based on its emergency-degree so as to provide vehicles with more safety information timely and accurately. In addition, an adaptive scheme is presented to ensure fast dissemination of messages in different network condition. We compare the performance of EDCast with those of three other representative protocols in a typical highway scenario. Simulation results indicate that EDCast achieves higher broadcast efficiency and less redundancy with less delivery delay. What we found demonstrates that it is feasible and necessary for incorporating information quantity of messages in designing an efficient safety message broadcast protocol.

  1. An Algebraic Approach to Unital Quantities and their Measurement

    Science.gov (United States)

    Domotor, Zoltan; Batitsky, Vadim

    2016-06-01

    The goals of this paper fall into two closely related areas. First, we develop a formal framework for deterministic unital quantities in which measurement unitization is understood to be a built-in feature of quantities rather than a mere annotation of their numerical values with convenient units. We introduce this idea within the setting of certain ordered semigroups of physical-geometric states of classical physical systems. States are assumed to serve as truth makers of metrological statements about quantity values. A unital quantity is presented as an isomorphism from the target system's ordered semigroup of states to that of positive reals. This framework allows us to include various derived and variable quantities, encountered in engineering and the natural sciences. For illustration and ease of presentation, we use the classical notions of length, time, electric current and mean velocity as primordial examples. The most important application of the resulting unital quantity calculus is in dimensional analysis. Second, in evaluating measurement uncertainty due to the analog-to-digital conversion of the measured quantity's value into its measuring instrument's pointer quantity value, we employ an ordered semigroup framework of pointer states. Pointer states encode the measuring instrument's indiscernibility relation, manifested by not being able to distinguish the measured system's topologically proximal states. Once again, we focus mainly on the measurement of length and electric current quantities as our motivating examples. Our approach to quantities and their measurement is strictly state-based and algebraic in flavor, rather than that of a representationalist-style structure-preserving numerical assignment.

  2. Synthesis and Comparison of Baseline Avian and Bat Use, Raptor Nesting and Mortality Information from Proposed and Existing Wind Developments: Final Report.

    2002-12-01

    Primarily due to concerns generated from observed raptor mortality at the Altamont Pass (CA) wind plant, one of the first commercial electricity generating wind plants in the U.S., new proposed wind projects both within and outside of California have received a great deal of scrutiny and environmental review. A large amount of baseline and operational monitoring data have been collected at proposed and existing U.S. wind plants. The primary use of the avian baseline data collected at wind developments has been to estimate the overall project impacts (e.g., very low, low, moderate, and high relative mortality) on birds, especially raptors and sensitive species (e.g., state and federally listed species). In a few cases, these data have also been used for guiding placement of turbines within a project boundary. This new information has strengthened our ability to accurately predict and mitigate impacts from new projects. This report should assist various stakeholders in the interpretation and use of this large information source in evaluating new projects. This report also suggests that the level of baseline data (e.g., avian use data) required to adequately assess expected impacts of some projects may be reduced. This report provides an evaluation of the ability to predict direct impacts on avian resources (primarily raptors and waterfowl/waterbirds) using less than an entire year of baseline avian use data (one season, two seasons, etc.). This evaluation is important because pre-construction wildlife surveys can be one of the most time-consuming aspects of permitting wind power projects. For baseline data, this study focuses primarily on standardized avian use data usually collected using point count survey methodology and raptor nest survey data. In addition to avian use and raptor nest survey data, other baseline data is usually collected at a proposed project to further quantify potential impacts. These surveys often include vegetation mapping and state or

  4. The construction of conserved quantities for linearly coupled oscillators and study of symmetries about the conserved quantities

    2007-01-01

    In this paper, the conserved quantities are constructed using two methods. The first method is by making an ansatz of the conserved quantity and then using the definition of Poisson bracket to obtain the coefficients in the ansatz. The main procedure for the second method is given as follows. Firstly, the coupled terms in Lagrangian are eliminated by changing the coordinate scales and rotating the coordinate axes, secondly, the conserved quantities are obtain in new coordinate directly, and at last, the conserved quantities are expressed in the original coordinates by using the inverse transform of the coordinates. The Noether symmetry and Lie symmetry of the infinitesimal transformations about the conserved quantities are also studied in this paper.

    Density functional reactivity theory (DFRT) employs the electron density and its related quantities to describe reactivity properties of a molecular system. Quantities from information theory such as Shannon entropy, Fisher information, and Ghosh-Berkowitz-Parr entropy are natural descriptors within the DFRT framework. They have been previously employed to quantify electrophilicity, nucleophilicity and the steric effect. In this work, we examine their scaling properties with respect to the total number of electrons. To that end, we considered their representations in terms of both the electron density and the shape function for isolated atoms and neutral molecules. We also investigated their atomic behaviors in different molecules with three distinct partitioning schemes: Bader's zero-flux, Becke's fuzzy atom, and Hirshfeld's stockholder partitioning. Strong linear relationships of these quantities as a function of the total electron population are reported for atoms, molecules, and atoms in molecules. These relationships reveal how these information-theoretic quantities depend on the molecular environment and the electron population. These trends also indicate how these quantities can be used to explore chemical reactivity for real chemical processes.

    JPL collaborated with experts from industry and other organizations to develop a conceptual model of quantities, units, dimensions, and values based on the current work of the ISO 80000 committee revising the International System of Units & Quantities based on the International Vocabulary of Metrology (VIM). By providing support for ISO 80000 in SysML via the International Vocabulary of Metrology (VIM), this conceptual model provides, for the first time, a standard-based approach for addressing issues of unit coherence and dimensional analysis into the practice of systems engineering with SysML-based tools. This conceptual model provides support for two kinds of analyses specified in the International Vocabulary of Metrology (VIM): coherence of units as well as of systems of units, and dimension analysis of systems of quantities. To provide a solid and stable foundation, the model for defining quantities, units, dimensions, and values in SysML is explicitly based on the concepts defined in VIM. At the same time, the model library is designed in such a way that extensions to the ISQ (International System of Quantities) and SI Units (Systeme International d Unites) can be represented, as well as any alternative systems of quantities and units. The model library can be used to support SysML user models in various ways. A simple approach is to define and document libraries of reusable systems of units and quantities for reuse across multiple projects, and to link units and quantity kinds from these libraries to Unit and QuantityKind stereotypes defined in SysML user models.

    The Noether symmetries and the conserved quantities for fractional Birkhoffian systems with time delay in terms of Riemann-Liouville fractional derivatives are proposed and studied. First, the fractional Pfaff-Birkhoff principle with time delay is proposed, and the fractional Birkhoff's equations with time delay are obtained. Second, based on the invariance of the fractional Pfaff action with time delay under a group of infinitesimal transformations, the Noether symmetric transformations and the Noether quasi-symmetric transformations of the system are defined, and the criteria of the Noether symmetries are established. Finally, the relationship between the symmetries and the conserved quantities are studied, and the Noether theorems for fractional Birkhoffian systems with time delay are established. Some examples are given to illustrate the application of the results.

    This paper explores Noether and Noether gauge symmetries of anisotropic universe model in f( R, T) gravity. We consider two particular models of this gravity and evaluate their symmetry generators as well as associated conserved quantities. We also find exact solution by using cyclic variable and investigate its behavior via cosmological parameters. The behavior of cosmological parameters turns out to be consistent with recent observations which indicates accelerated expansion of the universe. Next we study Noether gauge symmetry and corresponding conserved quantities for both isotropic and anisotropic universe models. We conclude that symmetry generators and the associated conserved quantities appear in all cases.

    The impact of the misalignment of the Vertex Locator of the LHCb experiment on the physical quantities of the decay "$D^{*+} \\rightarrow (D^{0}\\rightarrow K^{-}\\pi^{+}) \\pi^{+} $" is studied in this note. Different misalignments of the 2 halves are applied to Monte Carlo data and the variations of the physical quantities with respect to the case without misalignment are evaluated. The results show the importance of the VELO 2 half alignment which can significantly affect the physics performance in the large misalignment case. A misalignment equal to the precision of the real-time alignment of the Vertex Locator is found to have a negligible effect on the studied physical quantities.

  13. Combined heuristics for determining order quantity under time-varying demands

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The time-varying demands for a certain period are often assumed to be less than the basic economic order quantity (EOQ) so that total replenishment quantity rather than economic order quantity is normally considered by most of the heuristics.This acticle focuses on a combined heuristics method for determining order quantity under generalized time-varying demands.The independent policy (IP),abnormal independent policy (AIP) and dependent policies are studied and compared.Using the concepts of normal/abnormal periods and the properties of dependent policies,a dependent policy-based heuristics (DPH) is proposed for solving the order quantity problems with a kind of time-varying demands pattern under which the first period is normal.By merging the Silver-Meal (S-M) heuristics and the dependent policy-based heuristics (DPH),a combined heuristics (DPH/S-M) is developed for solving order quantity problems with generalized time-varying demands.The experimentation shows that (1) for the problem with one normal period,no matter which position the normal period stands,the DPH/S-M could not guarantee better than the S-M heuristics,however it is superior to the S-M heuristics in the case that the demands in the abnormal periods are in descending order,and (2) The DPH/S-M is superior to the S-M heuristics for problems with more than one normal period,and the more the number of normal periods,the greater the improvements.

    The inadvertent creation of transuranic waste carrying hazardous waste codes D001 and D002 requires the treatment of the material to eliminate the hazardous characteristics and allow its eventual shipment and disposal at the Waste Isolation Pilot Plant (WIPP). This report documents the effectiveness of two treatment methods proposed to stabilize both the unremediated and remediated nitrate salt waste streams (UNS and RNS, respectively). The two technologies include the addition of zeolite (with and without the addition of water as a processing aid) and cementation. Surrogates were developed to evaluate both the solid and liquid fractions expected from parent waste containers, and both the solid and liquid fractions were tested. Both technologies are shown to be effective at eliminating the characteristic of ignitability (D001), and the addition of zeolite was determined to be effective at eliminating corrosivity (D002), with the preferred option1 of zeolite addition currently planned for implementation at the Waste Characterization, Reduction, and Repackaging Facility. During the course of this work, we established the need to evaluate and demonstrate the effectiveness of the proposed remedy for debris material, if required. The evaluation determined that Wypalls absorbed with saturated nitrate salt solutions exhibit the ignitability characteristic (all other expected debris is not classified as ignitable). Follow-on studies will be developed to demonstrate the effectiveness of stabilization for ignitable Wypall debris. Finally, liquid surrogates containing saturated nitrate salts did not exhibit the characteristic of ignitability in their pure form (those neutralized with Kolorsafe and mixed with sWheat did exhibit D001). As a result, additional nitrate salt solutions (those exhibiting the oxidizer characteristic) will be tested to demonstrate the effectiveness of the remedy.

The objectives are to provide procedures for evaluating the technical aspects of proposals, and to provide procedures for determining the total costs of proposals considering both initial capital costs and annual operating and maintenance costs. The primary objective of Part 4 of this manual is to provide the utility engineer who has a special interest in the capabilities of FGDPRISM [Flue Gas Desulfurization PRocess Integration and Simulation Model] with more detailed discussions of its uses, requirements, and limitations. Part 5 is a case study in using this manual in the preparation of a purchase specification and in the evaluation of proposals received from vendors. The objectives are to demonstrate how the information contained in Parts 1 and 2 can be used to improve the technical content of an FGD system purchase specification; to demonstrate how the techniques presented in Part 3 can be used to evaluate proposals received in response to the purchase specification; and to illustrate how the FGDPRISM computer program can be used to establish design parameters for the specification and evaluate vendor designs.

  17. Multi-objective optimization for combined quality-quantity urban runoff control

    2012-12-01

    Urban development affects the quantity and quality of urban surface runoff. In recent years, the best management practices (BMPs) concept has been widely promoted for control of both quality and quantity of urban floods. However, means to optimize the BMPs in a conjunctive quantity/quality framework are still under research. In this paper, three objective functions were considered: (1) minimization of the total flood damages, cost of BMP implementation and cost of land-use development; (2) reducing the amount of TSS (total suspended solid) and BOD5 (biological oxygen demand), representing the pollution characteristics, to below the threshold level; and (3) minimizing the total runoff volume. The biological oxygen demand and total suspended solid values were employed as two measures of urban runoff quality. The total surface runoff volume produced by sub-basins was representative of the runoff quantity. The construction and maintenance costs of the BMPs were also estimated based on the local price standards. Urban runoff quantity and quality in the case study watershed were simulated with the Storm Water Management Model (SWMM). The NSGA-II (Non-dominated Sorting Genetic Algorithm II) optimization technique was applied to derive the optimal trade off curve between various objectives. In the proposed structure for the NSGA-II algorithm, a continuous structure and intermediate crossover were used because they perform better as far as the optimization efficiency is concerned. Finally, urban runoff management scenarios were presented based on the optimal trade-off curve using the k-means method. Subsequently, a specific runoff control scenario was proposed to the urban managers.

  19. PCP METHODOLOGY FOR DETERMINING DOSE RATES FOR SMALL GRAM QUANTITIES IN SHIPPING PACKAGINGS

    Energy Technology Data Exchange (ETDEWEB)

    Nathan, S.

    2011-08-23

    The Small Gram Quantity (SGQ) concept is based on the understanding that small amounts of hazardous materials, in this case radioactive materials, are significantly less hazardous than large amounts of the same materials. This study describes a methodology designed to estimate an SGQ for several neutron and gamma emitting isotopes that can be shipped in a package compliant with 10 CFR Part 71 external radiation level limits regulations. These regulations require packaging for the shipment of radioactive materials perform, under both normal and accident conditions, the essential functions of material containment, subcriticality, and maintain external radiation levels within regulatory limits. 10 CFR 71.33(b)(1)(2)&(3) state radioactive and fissile materials must be identified and their maximum quantity, chemical and physical forms be included in an application. Furthermore, the U.S. Federal Regulations require application contain an evaluation demonstrating the package (i.e., the packaging and its contents) satisfies the external radiation standards for all packages (10 CFR 71.31(2), 71.35(a), & 71.47). By placing the contents in a He leak-tight containment vessel, and limiting the mass to ensure subcriticality, the first two essential functions are readily met. Some isotopes emit sufficiently strong photon radiation that small amounts of material can yield a large external dose rate. Quantifying of the dose rate for a proposed content is a challenging issue for the SGQ approach. It is essential to quantify external radiation levels from several common gamma and neutron sources that can be safely placed in a specific packaging, to ensure compliance with federal regulations. The Packaging Certification Program (PCP) Methodology for Determining Dose Rate for Small Gram Quantities in Shipping Packagings described in this report provides bounding mass limits for a set of proposed SGQ isotopes. Methodology calculations were performed to estimate external radiation levels

These quantities include Gamma emission (GR), sonic transient time (DT) and Neutron porosity (NPHI) which are collected from four wells of a reservoir. To quantify mutual interaction of petrophysical quantities, joint multifractal random walk is implemented. This approach is based on the mutual multiplicative cascade notion in the multifractal formalism and in this approach $L_0$ represents a benchmark to describe the nature of cross-correlation between two series. The analysis of the petrophysical quantities revealed that GR for all wells has strongly multifractal nature due to the considerable abundance of large fluctuations in various scales. The variance of probability distribution function, $\\lambda_{\\ell}^2$, at scale $\\ell$ and its intercept determine the multifractal properties of the data sets sourced by probability density function. The value of $\\...

    Digitization projects should focus on quantity rather than quality. Increasing quantities of information produce qualitatively more valuable services. Online writing and searching are now common, and it is only online reading that is still limiting our use of online books. New interfaces might increase our willingness to read online, which should be encouraged rather than fought, since it represents an increase both the amount of information available and the participation of more people in the writing and exchange of information.

    2008-01-01

    A close study of Heisenberg uncertainty principles reveals many significant facts, and all four major physical quantities, energy, time, momentum and length, have both lower and upper limits. Now, many questions come up. What are these limits? Some answers may lead to the understanding of the development of our universe. What is the shortest limit of time? At the beginning of big bang, there exists a tre-mendously short time, the Planck time. This may be just the shortest time limit in our universe. The longest time limit might be the lifetime of our universe. The longest length might be the final diameter of our expanding universe. All these lead to a finite universe. Two more coupling formulae are formed for the other two pairs of physical quantities, mass and speed, thermal energy and temperature. These four physical quantities must also have limits. We already knew that speed has upper limit and temperature has lower limit. By these two formulae, Planck and Einstein equations are derived directly. Since most other physical quantities are somewhat related to these major physical quantities, it seems that there exists a principle of limitation of physical quantities. A quantitative sketch of big bang is described. It also shows that our universe will contract back to another big bang. The principle of limitation opens up some fields of investigation. It may bring nature back to the harmony and determined world described by classical physics.

  10. Ideas on the emergence of life by a quantity-to-quality transition of the abiotic matter

    Kolb, Vera M.

    2005-09-01

    We review and re-examine the idea that life emerged by a quantity-to-quality transition of the abiotic matter. This idea was originally proposed by the dialectical materialists, who are the proponents of the materialistic approach to the Hegel's laws of dialectics. We propose in this paper that the universal feature of the quantity-to-quality transitions is a change in the organization of the system. We also discuss Jean-Paul Sartre's view on the application of the laws of dialectics to the nature and to the origins of life.

    The Systems Development Report represents the third major step in the Clark County Socioeconomic Impact Assessment of the Proposed High-Level Nuclear Waste Repository at Yucca Mound Nevada. The first of these steps was to forge a Research Design that would serve as a guide for the overall research process. The second step was the construction of the Base Case, the purpose of which was to describe existing conditions in Clark County in the specified analytic areas of Economic-Demographic/Fiscal, Emergency Planning and Management, Transportation and Sociocultural analysis. The base case description will serve as a basis for assessing changes in these topic areas that might result from the Yucca Mountain project. These changes will be assessed by analyzing conditions with and without repository development in the county. Prior to performing such assessments, however, the snapshot type of data found in the base case must be operationalized or systematized to allow for more dynamic data utilization. In other words, a data system that can be used to analyze the consequences of the introduction of different variables (or variable values) in the Clark County context must be constructed. Such a system must be capable of being updated through subsequent data collection and monitoring efforts to both provide a rolling base case and supply information necessary to construct trend analyses. For example, during the Impact Assessment phase of the study process, the without repository analysis is accomplished by analyzing growth for the county given existing conditions and likely trends. These data are then compared to the with Yucca Mountain project conditions anticipated for the county. Similarly, once the emergency planning management and response needs associated with the repository are described, these needs will be juxtaposed against existing (and various future) capacity(ies) in order to determine the nature and magnitude of impacts in this analytic area.

    While numerosity-representation and enumeration of different numbers of objects-and quantity discrimination in particular have been studied in a wide range of species, very little is known about the numerical abilities of animals in the wild. This study examined spontaneous relative quantity judgments (RQJs) by wild North Island robins (Petroica longipes) of New Zealand. In Experiment 1, robins were tested on a range of numerical values of up to 14 versus 16 items, which were sequentially presented and hidden. In Experiment 2, the same numerical contrasts were tested on a different group of subjects but quantities were presented as whole visible sets. Experiment 3 involved whole visible sets that comprised of exceedingly large quantities of up to 56 versus 64 items. While robins shared with other species a ratio-based representation system for representing very large values, they also appeared to have developed an object indexing system with an extended upper limit (well beyond 4) that may be an evolutionary response to ecological challenges faced by scatter-hoarding birds. These results suggest that cognitive mechanism influencing an understanding of physical quantity may be deployed more flexibly in some contexts than previously thought, and are discussed in light of findings across other mammalian and avian species.

  13. Aerobic digestion reduces the quantity of antibiotic resistance genes in residual municipal wastewater solids

    Full Text Available Numerous initiatives have been undertaken to circumvent the problem of antibiotic resistance, including the development of new antibiotics, the use of narrow spectrum antibiotics, and the reduction of inappropriate antibiotic use. We propose an alternative but complimentary approach to reduce antibiotic resistant bacteria by implementing more stringent technologies for treating municipal wastewater, which is known to contain large quantities of antibiotic resistant bacteria and antibiotic resistance genes (ARGs. In this study, we investigated the ability of conventional aerobic digestion to reduce the quantity of ARGs in untreated wastewater solids. A bench-scale aerobic digester was fed untreated wastewater solids collected from a full-scale municipal wastewater treatment facility. The reactor was operated under semi-continuous flow conditions for more than 200 days at a residence time of approximately 40 days. During this time, the quantities of tet(A, tet(W, and erm(B decreased by more than 90%. In contrast, intI1 did not decrease, and tet(X increased in quantity by 5-fold. Following operation in semi-continuous flow mode, the aerobic digester was converted to batch mode to determine the first-order decay coefficients, with half-lives ranging from as short as 2.8 days for tet(W to as long as 6.3 days for intI1. These results demonstrated that aerobic digestion can be used to reduce the quantity of antibiotic resistance genes in untreated wastewater solids, but that rates can vary substantially depending on the reactor design (i.e., batch versus continuous-flow and the specific ARG.

    1997-12-31

    In the continuing debate on the decommissioning and disposal of North Sea oil and gas platforms, the use of redundant structures as artificial reefs remains an untried possibility. It has been suggested that selected, clean, inert steel components could be used to create offshore reefs to attract finfish, to the benefit fisheries and fishermen. This might be an innovative and cost-effective use of these ``materials and opportunity``, and therefore should be examined more fully before the predicted 20-30 year period of steady decommissioning activity in the North Sea begins in earnest. This report relates on reviewing the use and effectiveness of artificial reefs, summarize existing knowledge of the reef effect of North Sea platforms, outline possible scenarios for the creation and exploitation of platform reefs in the North Sea, highlight gaps in knowledge, and to propose programmes of work to study the reef effect at an inshore and an offshore site in the North Sea. 5 tabs.

    Full Text Available Few researches have been concerned about relation between children’s spatial thinking and number sense. Narrowing for this small research, we focused on one component of spatial thinking, that is structuring objects, and one component of number senses, that is cardinality by determining quantities. This study focused on a design research that was conducted in Indonesia in which we investigated pre-school children’s (between 2 and 3.5 years old ability in making structured arrangement and their ability to determine the quantities by looking at the arrangements. The result shows us that some of the children were able to make such arrangement. However, the children found difficulties either to determine quantities from those arrangements or to compare some structures to easily recognize number of objects.

    In this work we apply the Landau-Lifshitz pseudotensor flux formalism to the calculation of the total mass and the total angular momentum during the evolution of a binary black hole system. We also compare its performance with the traditional integrations for the global quantities. It shows that the advantage of the pseudotensor flux formalism is the smoothness of the numerical value of the global quantities, especially of the total angular momentum. Although the convergence behavior of the global quantities with the pseudotensor flux method is only comparable with the ones with the traditional method, the smoothness of its numerical value allows using a larger radius for surface integration to obtain more accurate result.

  1. Multimodal semantic quantity representations: further evidence from Korean Sign Language

    Frank eDomahs

    2012-01-01

    Full Text Available Korean deaf signers performed a number comparison task on pairs of Arabic digits. In their RT profiles, the expected magnitude effect was systematically modified by properties of number signs in Korean Sign Language in a culture-specific way (not observed in hearing and deaf Germans or hearing Chinese. We conclude that finger-based quantity representations are automatically activated even in simple tasks with symbolic input although this may be irrelevant and even detrimental for task performance. These finger-based numerical representations are accessed in addition to another, more basic quantity system which is evidenced by the magnitude effect. In sum, these results are inconsistent with models assuming only one single amodal representation of numerical quantity.

    2014-04-01

    Full Text Available In the recent decade, studying the economic order quantity (EOQ models with imperfect quality has appealed to many researchers. Only few papers are published discussing EOQ models with imperfect items in a supply chain. In this paper, a two-echelon decentralized supply chain consisting of a manufacture and a supplier that both face just in time (JIT inventory problem is considered. It is sought to find the optimal number of the shipments and the quantity of each shipment in a way that minimizes the both manufacturer’s and the supplier’s cost functions. To the authors’ best knowledge, this is the first paper that deals with imperfect items in a decentralized supply chain. Thereby, three different game theoretical solution approaches consisting of two non-cooperative games and a cooperative game are proposed. Comparing the results of three different scenarios with those of the centralized model, the conclusions are drawn to obtain the best approach.

    This paper proposes a new concept of the conformal invariance and the conserved quantities for Birkhoff systems under second-class Mei symmetry. The definition about conformal invariance of Birkhoff systems under second-class Mei symmetry is given. The conformal factor in the determining equations is found. The relationship between Birkhoff system's conformal invariance and second-class Mei symmetry are discussed. The necessary and sufficient conditions of conformal invariance, which are simultaneously of second-class symmetry, are given. And Birkhoff system's conformal invariance may lead to corresponding Mei conserved quantities, which is deduced directly from the second-class Mei symmetry when the conformal invariance satisfies some conditions. Lastly, an example is provided to illustrate the application of the result.

  5. Difference in quantity discrimination in dogs and wolves

    Friederike eRange

    2014-11-01

    Full Text Available Certain aspects of social life, such as engaging in intergroup conflicts, as well as challenges posed by the physical environment, may facilitate the evolution of quantity discrimination. In lack of excessive comparative data, one can only hypothesize about its evolutionary origins, but human-raised wolves performed well when they had to choose the larger of two sets of 1 to 4 food items that had been sequentially placed into two opaque cans. Since in such paradigms, the animals never see the entire content of either can, their decisions are thought to rely on mental representation of the two quantities rather than on some perceptual factors such as the overall volume or surface area of the two amounts. By equaling the time that it takes to enter each quantity into the cans or the number of items entered, one can further rule out the possibility that animals simply choose based on the amount of time needed to present the two quantities. While the wolves performed well even in such a control condition, dogs failed to choose the larger one of two invisible quantities in another study using a similar paradigm. Because this disparity could be explained by procedural differences, in the current study, we set out to test dogs that were raised and kept identically as the previously tested wolves using the same set-up and procedure. Our results confirm the former finding that dogs, in comparison to wolves, have inferior skills to represent quantities mentally. This seems to be in line with a Frank's (1980 hypothesis suggesting that domestication altered the information processing of dogs. However, as discussed, also alternative explanations may exist.

    This report covers a broad range of topics in theoretical nuclear physics, intermediate energy physics, and nuclear astrophysics. Primary emphasis is placed on understanding the nature of the nucleon-nucleon and meson-nucleon interactions and on related questions regarding the structure of baryons. A number of these questions are addressed with the aid of the chiral bag model. Starting from the free interaction, many-body techniques are used to construct the effective interaction between nucleons in nuclei and nuclear media and optical potentials for the description of the scattering of nucleons by nuclei. A wide range of nuclear phenomena are amenable to analysis using such effective interactions. Among the most interesting are nuclear giant resonances, for which are offered both new semiclassical insight and a new dynamical theory of nuclear vibrations that emphasizes the importance of the energy dependence of the effective interaction. The extension of Jastrow/hypernetted chain techniques and a better understanding of their content has led to a better description of the ground-state correlations in nuclear matter and a variety of other condensed systems. The equation of state of nuclear matter at densities of astrophysical interest is discussed. It is possible to understand the properties of pulsars given the interactions between their constituents. A description of pulsar formation and of the effects of the shock wave generated in the collapse of large stars is given. Heavy-ion reactions, quasimolecular states, and energy dissipation are studied through the excitation of collective excitations within a semiclassical framework. Items in this report are of the nature of extended abstracts. References to complete papers are given.

  13. Practical thermodynamic quantities for aqueous vanadium- and iron-based flow batteries

    2014-12-01

    A simple method for experimentally determining thermodynamic quantities for flow battery cell reactions is presented. Equilibrium cell potentials, temperature derivatives of cell potential (dE/dT), Gibbs free energies, and entropies are reported here for all-vanadium, iron-vanadium, and iron-chromium flow cells with state-of-the-art solution compositions. Proof is given that formal potentials and formal temperature coefficients can be used with modified forms of the Nernst Equation to quantify the thermodynamics of flow cell reactions as a function of state-of-charge. Such empirical quantities can be used in thermo-electrochemical models of flow batteries at the cell or system level. In most cases, the thermodynamic quantities measured here are significantly different from standard values reported and used previously in the literature. The data reported here are also useful in the selection of operating temperatures for flow battery systems. Because higher temperatures correspond to lower equilibrium cell potentials for the battery chemistries studied here, it can be beneficial to charge a cell at higher temperature and discharge at lower temperature. Proof-of-concept of improved voltage efficiency with the use of such non-isothermal cycling is given for the all-vanadium redox flow battery, and the effect is shown to be more pronounced at lower current densities.

    A survey of endangered waterbirds on Maui and Oahu was conducted during August and September 1993 to identify potential waterbird habitats within the general area of the proposed Hawaii Geothermal Project transmission corridor and to assess the potential impacts to endangered waterbird of installing and operating a high voltage transmission line from the Island of Hawaii to the islands of Oahu and Maui. Annual waterbird survey information and other literature containing information on specific wetland sites were summarized. Literature describing impacts of overhead transmission lines on birds was used to evaluate potential impacts of the proposed project on endangered waterbirds, resident wading birds, and migratory shorebirds and waterfowl. On Oahu, five wetland habitats supporting endangered Hawaiian waterbirds were identified within 2.5 miles of the proposed transmission line corridor. On Maui, three wetland habitats supporting endangered Hawaiian waterbirds were identified within the general area of the proposed transmission line corridor. Several of the wetlands identified on Oahu and Maui also supported resident wading birds and migratory shorebirds and waterfowl. Endangered waterbirds, resident wading birds, and migratory birds may collide with the proposed transmission lines wires. The frequency and numbers of bird collisions is expected to be greater on Oahu than on Maui because more wetland habitat exists and greater numbers of birds occur in the project area on Oahu. In addition, the endangered Hawaiian goose and the endangered Hawaiian petrel may be impacted by the proposed segment of the Hawaii Geothermal Project transmission line on Maui.

  1. Quantity and unit extraction for scientific and technical intelligence analysis

    Science.gov (United States)

    David, Peter; Hawes, Timothy

    2017-05-01

    Scientific and Technical (S and T) intelligence analysts consume huge amounts of data to understand how scientific progress and engineering efforts affect current and future military capabilities. One of the most important types of information S and T analysts exploit is the quantities discussed in their source material. Frequencies, ranges, size, weight, power, and numerous other properties and measurements describing the performance characteristics of systems and the engineering constraints that define them must be culled from source documents before quantified analysis can begin. Automating the process of finding and extracting the relevant quantities from a wide range of S and T documents is difficult because information about quantities and their units is often contained in unstructured text with ad hoc conventions used to convey their meaning. Currently, even simple tasks, such as searching for documents discussing RF frequencies in a band of interest, is a labor intensive and error prone process. This research addresses the challenges facing development of a document processing capability that extracts quantities and units from S and T data, and how Natural Language Processing algorithms can be used to overcome these challenges.

    2003-01-01

    Numerical abilities are thought to rest on the integration of two distinct systems, a verbal system of number words and a non-symbolic representation of approximate quantities. This view has lead to the classification of acalculias into two broad categories depending on whether the deficit affects the verbal or the quantity system. Here, we test the association of deficits predicted by this theory, and particularly the presence or absence of impairments in non-symbolic quantity processing. We describe two acalculic patients, one with a focal lesion of the left parietal lobe and Gerstmann's syndrome and another with semantic dementia with predominantly left temporal hypometabolism. As predicted by a quantity deficit, the first patient was more impaired in subtraction than in multiplication, showed a severe slowness in approximation, and exhibited associated impairments in subitizing and numerical comparison tasks, both with Arabic digits and with arrays of dots. As predicted by a verbal deficit, the second patient was more impaired in multiplication than in subtraction, had intact approximation abilities, and showed preserved processing of non-symbolic numerosities.

  1. Analysis of the proposed EU regulation concerning biocide products and its opportunities for alternative approaches and a toxicology for the 21st century (t4 report).

    Science.gov (United States)

    Ferrario, Daniele; Rabbit, Richard R

    2012-01-01

    On June 12, 2009, the European Commission adopted a proposal for a Regulation concerning the placement on the market and use of biocidal products, which, when it enters into force on January 1, 2013, will repeal and replace Directive 98/8/EC. The main reason for the revision of the current Directive was to promote best practices for environmental and human health protection, along with implementation of current developments in safety testing in order to create safer biocides. Moreover, the proposed Regulation aims to take into consideration the newest legislation on chemicals. This article evaluates the proposed Regulation in comparison to Directive 98/8/EC. Although the new proposal requires the sharing of vertebrate animal test data, both for product authorization and for newly developed active substances, it misses - in contrast to REACH - the opportunity to recognize the accelerating development of alternative approaches to animal testing, most recently with new momentum provided by "Toxicity Testing for the 21st Century", and to support the evolution of toxicology towards a new approach to testing. The new methods promise not only to decrease animal pain and suffering, but also to provide faster results and better prediction for human risk assessment compared to traditional methods. Unfortunately, methods mandated for human risk assessment in the proposal are still mainly based on traditional animal study extrapolation. We put forward and discuss possible alternative strategies, such as in vitro testing, integrated testing strategies, toxicokinetics, "omics", systems biology, bioinformatics, and computational modeling, all of which could be more encouraged by the proposal. Current opportunities to improve our tools for biocide risk assessment are discussed, delineating advantages, limitations, and development needs. It is suggested to open the proposed Regulation to alternative approaches that are based on human biology more than on extrapolation from animals

    Full Text Available Purpose: The aim of this paper is to deal with the supply chain management (SCM with quantity discount policy under the complex fuzzy environment, which is characterized as the bi-fuzzy variables. By taking into account the strategy and the process of decision making, a bi-fuzzy nonlinear multiple objective decision making (MODM model is presented to solve the proposed problem.Design/methodology/approach: The bi-fuzzy variables in the MODM model are transformed into the trapezoidal fuzzy variables by the DMs's degree of optimism ?1 and ?2, which are de-fuzzified by the expected value index subsequently. For solving the complex nonlinear model, a multi-objective adaptive particle swarm optimization algorithm (MO-APSO is designed as the solution method.Findings: The proposed model and algorithm are applied to a typical example of SCM problem to illustrate the effectiveness. Based on the sensitivity analysis of the results, the bi-fuzzy nonlinear MODM SCM model is proved to be sensitive to the possibility level ?1.Practical implications: The study focuses on the SCM under complex fuzzy environment in SCM, which has a great practical significance. Therefore, the bi-fuzzy MODM model and MO-APSO can be further applied in SCM problem with quantity discount policy.Originality/value: The bi-fuzzy variable is employed in the nonlinear MODM model of SCM to characterize the hybrid uncertain environment, and this work is original. In addition, the hybrid crisp approach is proposed to transferred to model to an equivalent crisp one by the DMs's degree of optimism and the expected value index. Since the MODM model consider the bi-fuzzy environment and quantity discount policy, so this paper has a great practical significance.

  3. Quantum Physics and Mathematical Debates Concerning the Problem of the Ontological Priority between Continuous Quantity and Discrete Quantity

    Science.gov (United States)

    Pin, Victor Gómez

    In his book about the Categories (that is about the ultimate elements of classification and order), in the chapter concerning the quantity (IV, 20) Aristotle says that this concept recovers two kinds of modalities: the discrete quantity and the continuous quantity and he gives as examples the number for the first one; line, surface, solid, times and space for the second one. The main philosophical problem raised by this text is to determine which of the two modalities of the quantity has the ontological priority over the other (given two concepts A and B, we assume that A has ontological priority over B if every entity that possesses the quality B possesses necessarily the quality A). The problem is magnified by the fact that space, which in some part of Aristotle's Physics is mentioned not only as a category properly speaking but even as the main category whose power can be amazing, is in the evoked text of the Categories's Book reduced to expression of the continuum, and sharing this condition with time. In this matter the controversy is constant through the common history of Science and Philosophy.

  4. Aggregating land use quantity and intensity to link water quality in upper catchment of Miyun Reservoir

    Science.gov (United States)

    Xu, E.

    2015-12-01

    Land use is closely related to hydrological and biochemical processes influencing the water quality. Quantifying relationship between both of them can help effectively manage land use to improve water quality. Previous studies majorly utilized land use quantity as an indicator to link water quality parameters, which lacked an insight to the influence of land use intensity. Taking upper catchment of Miyun Reservoir as a case study, we proposed a method of aggregating land use quantity and intensity to build a new land use indicator and investigated its explanation empower on water quality. Six nutrient concentrations from 52 sub-watersheds covering the whole catchment were used to characterize spatial distributions of water eutrophication. Based on spatial techniques and empirical conversion coefficients, combined remote sensing with socio-economic statistical data, land use intensity was measured and mapped visually. Then the new land use indicator was calculated and linked to nutrient concentrations by Pearson correlation coefficients. Results demonstrated that our new land use indicator incorporating intensity information can quantify the potential different nutrients exporting abilities from land uses. Comparing to traditional indicators only characterized by land use quantity, most Pearson correlation coefficients between new indicator and water nutrient concentrations increased. New information enhanced the explanatory power of land use on water nutrient concentrations. Then it can help better understand the impact of land use on water quality and guide land use management for supporting decision making.

    Directory of Open Access Journals (Sweden)

    Chui-Yu Chiu

    2009-01-01

    Full Text Available Problem statement: In reality, there are of various products such as liquids, volatile, medicines and materials, in which the rate of deterioration is very large. However, little attention has been mentioned what the effects of deterioration occur in most inventory systems. Also, the loss of the deterioration should not be neglected as an important issue. Approach: In this study, we proposed the problem of determining the Economic Order Quantity (EOQ for exponentially deteriorating items under the conditions of permissible delay in payments. Recent researches revealed that the payment for the product must be made forthwith when the order quantity is less than the allowable delay in payments. The fixed trade credit period was permitted, or else. Therefore, we utilized the fuzzy theory to implement more considerable answers via numerical examples which were provided to illustrate the results clearly at the end of study. Results: This study discussed the optimal replenishment cycle time for an exponentially deteriorating product under conditions of permissible delay in payments to take the order quantity into account. Conclusion/Recommendations: This study presented another fuzzy environment inventory model which accounts for the permissible delay in payments offered by supplier to the retailer. From the results, it can be concluded that another point of view to decision makers in uncertainty.

  7. Generalized Field Theoretical Approach to General Relativity and Conserved Quantities in Anti-de Sitter Spacetimes

    CERN Document Server

    Pinto-Neto, N

    2000-01-01

    A new prescription to calculate the total energies and angular momenta of asymptotically $(d+1)$-dimensional anti-de Sitter spacetimes is proposed. The method is based on an extension of the field theoretical approach to General Relativity to the case where there is an effective cosmological constant. A $(d-1)$-form $\\Omega$ is exhibited which, when integrated on asymptotic $(d-1)$-dimensional boundary surfaces, yields the values of those conserved quantities. The calculations are gauge independent once asymptotic conditions are not violated . Total energies and angular momenta of some known solutions in four and five dimensions are calculated agreeing with standard results.

    2013-09-01

    This paper presents the results of experimental studies of the quantity of air liberated in the flow of aviation fuel in the pipe at a low pressure. Experiments were carried out in the pressure range from 0.2 to 1.0 bar, and the temperature was varied from -20 to +20°C. We propose a method for determining the mass concentration of air dissolved in the fuel measured with the help of a chromatograph. An attempt to use an optical method for measuring the gas content of the flow has shown that it is useful in combination with a chromatographic method needed to calibrate the optical scheme.

    2005-05-01

    We report a simple and effective method for the generation of bulk-quantity nanorods of manganese oxide, Mn3O4, under surroundings of a suitable surfactant and alkaline solution. It is found that the Mn3O4 nanorod is smooth, straight, and that the geometrical shape is structurally perfect, which is produced with lengths from several hundreds nanometers to a few micrometers, and diameters range from 10nmto30nm. We amazedly found that the dripping speed of the NaOH solution plays an important role in formation of bulk-quantity Mn3O4 nanorods. The difference of dripping speed of the NaOH solution leads to a large difference of Mn3O4 morphologies, which is observed in the transmission electron microscopy images. The growth of the Mn3O4 nanorods is suggested first to follow a self-catalyzed solution-liquid-solid mechanism.

  11. Sleep quantity and quality is not compromised during planned burn shifts of less than 12 h.

    Science.gov (United States)

    Vincent, Grace E; Aisbett, Brad; Hall, Sarah J; Ferguson, Sally A

    Planned burning is a preventative strategy aimed at decreasing fuel loads to reduce the severity of future wildfire events. During planned burn operations, firefighters can work long shifts. Furthermore, remote burning locations may require firefighters to sleep away from home between shifts. The existing evidence surrounding firefighters' sleep during such operations is exclusively anecdotal. The aims of the study were to describe firefighters' sleep during planned burn operations and evaluate the impact of the key operational factors (shift start time, shift length and sleeping location) that may contribute to inadequate sleep. Thirty-three salaried firefighters were recruited from Australia's fire agencies and sleep was measured objectively using wrist actigraphy for four weeks. All variables were examined in two conditions: (1) burn days, and (2) non-burn days. Time in bed, total sleep time, sleep latency and sleep efficiency were evaluated objectively. Subjective reports of pre- and post-sleep fatigue, sleep location, sleep quality, sleep quantity, number of times woken and sleep timing were also recorded. Analyses revealed no differences in measures of sleep quantity and quality when comparing non-burn and burn days. Total sleep time was less when planned burn shifts were >12 h. However, on burn days, work shift start time as well as sleeping location did not impact firefighters' sleep quantity. Self-reported levels of pre- and post-sleep fatigue were greater on burn days compared to non-burn days. These findings indicate that sleep quantity and quality are not compromised during planned burn operations <12 h in duration.

    2005-11-01

    The purpose of this work is to test the chief principle of brainstorming, formulated as "quantity generates quality." The study is included within a broad program whose goal is to detect the strong and weak points of creative techniques. In a sample of 69 groups, containing between 3 and 8 members, the concurrence of two commonly accepted criteria was established as a quality rule: originality and utility or value. The results fully support the quantity-quality relation (r = .893): the more ideas produced to solve a problem, the better quality of the ideas. The importance of this finding, which supports Osborn's theory, is discussed, and the use of brainstorming is recommended to solve the many open problems faced by our society.

    and conscientious verbal evaluation. The term pseudo-quantity is new, but the phenomenon is well known to researchers and has become the subject of a rapidly growing stream of literature.1 The new term would primarily be intended to provide insight into the on-going mechanisms and processes that underlie this phenomenon. Furthermore, this term has a critical potential that is urgently needed at a time when many individuals erroneously believe that pseudoquantities can be used to gain both time and perspective. In the first part of the article, I will present the new concept and its background in the concepts of quality and quantity. The importance of this term is pertinent to the founding of New Public Management (NPM in the public sector. NPM will be treated in the following section. I will specifically highlight how this process influences education and research. In the conclusion, I summarise my argument and provide insight regarding a possible alternative.

While there are extensive experimental observations and established ideas regarding desorption of ions from the surfaces of aqueous salt solutions, a more successful discussion of the theory has recently emerged, which allows the quantitative calculation of the distribution of ions in the surface region. Surface Tension and Related Thermodynamic Quantities of Aqueous Electrolyte Solutions provides a d

  18. Monitoring the eye lens: which dose quantity is adequate?

    Recent epidemiological studies suggest a rather low dose threshold (below 0.5 Gy) for the induction of a cataract of the eye lens. Some other studies even assume that there is no threshold at all. Therefore, protection measures have to be optimized and current dose limits for the eye lens may be reduced in the future. The question of which personal dose equivalent quantity is appropriate for monitoring the dose to the eye lens arises from this situation. While in many countries dosemeters calibrated in terms of the dose equivalent quantity H{sub p}(0.07) have been seen as being adequate for monitoring the dose to the eye lens, this might be questionable in the case of reduced dose limits and, thus, it may become necessary to use the dose equivalent quantity H{sub p}(3) for this purpose. To discuss this question, the dose conversion coefficients for the equivalent dose of the eye lens (in the following eye lens dose) were determined for realistic photon and beta radiation fields and compared with the values of the corresponding conversion coefficients for the different operational quantities. The values obtained lead to the following conclusions: in radiation fields where most of the dose comes from photons, especially x-rays, it is appropriate to use dosemeters calibrated in terms of H{sub p}(0.07) on a slab phantom, while in other radiation fields (dominated by beta radiation or unknown contributions of photon and beta radiation) dosemeters calibrated in terms of H{sub p}(3) on a slab phantom should be used. As an alternative, dosemeters calibrated in terms of H{sub p}(0.07) on a slab phantom could also be used; however, in radiation fields containing beta radiation with the end point energy near 1 MeV, an overestimation of the eye lens dose by up to a factor of 550 is possible.

    Physical quantities and physical dimensions are among the first concepts encountered by students in their undergraduate career. In this pedagogical review, I will start from these concepts and, using the powerful tool of dimensional analysis, I will embark in a journey through various branches of physics, from basic mechanics to quantum gravity. I will also discuss a little bit about the fundamental constants of Nature, the so-called "cube of Physics", and the natural system of units.

    The thermodynamic quantities for the gases of massless particles with spin s = 1/2, 1, 3/2, 2 around static spherical black holes are investigated by using the brick-wall method. The appearance of the spin-dependent subleading terms is demonstrated and the terms are shown to contain not only the linear and quadratic terms of the spins but also a zero-power term of the spins.

  3. Consumer-resource dynamics: quantity, quality, and allocation.

    Directory of Open Access Journals (Sweden)

    Wayne M Getz

    Full Text Available BACKGROUND: The dominant paradigm for modeling the complexities of interacting populations and food webs is a system of coupled ordinary differential equations in which the state of each species, population, or functional trophic group is represented by an aggregated numbers-density or biomass-density variable. Here, using the metaphysiological approach to model consumer-resource interactions, we formulate a two-state paradigm that represents each population or group in a food web in terms of both its quantity and quality. METHODOLOGY AND PRINCIPAL FINDINGS: The formulation includes an allocation function controlling the relative proportion of extracted resources to increasing quantity versus elevating quality. Since lower quality individuals senescence more rapidly than higher quality individuals, an optimal allocation proportion exists and we derive an expression for how this proportion depends on population parameters that determine the senescence rate, the per-capita mortality rate, and the effects of these rates on the dynamics of the quality variable. We demonstrate that oscillations do not arise in our model from quantity-quality interactions alone, but require consumer-resource interactions across trophic levels that can be stabilized through judicious resource allocation strategies. Analysis and simulations provide compelling arguments for the necessity of populations to evolve quality-related dynamics in the form of maternal effects, storage or other appropriate structures. They also indicate that resource allocation switching between investments in abundance versus quality provide a powerful mechanism for promoting the stability of consumer-resource interactions in seasonally forcing environments. CONCLUSIONS/SIGNIFICANCE: Our simulations show that physiological inefficiencies associated with this switching can be favored by selection due to the diminished exposure of inefficient consumers to strong oscillations associated with the

  4. Synchrotron radiation shielding design and ICRP radiological protection quantities.

    Protection and operational quantities as defined by the International Commission on Radiological Protection (ICRP) and the International Commission on Radiation Units and Measurements (ICRU) are the two sets of quantities recommended for use in radiological protection for external radiation. Since the '80s, the protection quantities have evolved from the concept of dose equivalent to effective dose equivalent to effective dose, and the associated conversion coefficients have undergone changes. In this work, the influence of three different versions of ICRP photon dose conversion coefficients in the synchrotron radiation shielding calculations of an experimental enclosure has been examined. The versions are effective dose equivalent (ICRP Publication 51), effective dose (ICRP Publication 74), and effective dose (ICRP Publication 116) conversion coefficients. The sources of the synchrotron radiation white beam into the enclosure were a bending magnet, an undulator and a wiggler. The ranges of photons energy from these sources were 10-200 keV for the bending magnet and undulator, and 10-500 keV for the wiggler. The design criterion aimed a radiation leakage less than 0.5 µSv h(-1) from the enclosure. As expected, larger conversion coefficients in ICRP Publication 51 lead to higher calculated dose rates. However, the percentage differences among the calculated dose rates get smaller once shielding is added, and the choice of conversion coefficients set did not affect the final shielding decision.

    2009-01-01

    Based on the principle of field synergy for heat transfer enhancement, the concept of physical quantity synergy in the laminar flow field is proposed in the present study according to the physical mechanism of convective heat transfer between fluid and tube wall. The synergy regulation among physical quantities of fluid particle is revealed by establishing formulas reflecting the relation between synergy angles and heat transfer enhancement. The physical nature of enhancing heat transfer and reducing flow resistance, which is directly associated with synergy angles α,βγ,φ, θ and ψ, is also explained. Be-sides, the principle of synergy among physical quantities is numerically verified by the calculation of heat transfer and flow in a thin cylinder-interpolated tube, which may guide the optimum design for better heat transfer unit and high-efficiency heat exchanger.

    Iwasa, Yukikazu; Rabinowicz, E.

    1987-03-09

    Principal objective of this renewal proposal is to develop a friction model which predicts whether a sliding system will give steady or unsteady sliding behavior at low speeds and to advance the basic understanding of the friction process. The proposed program consists of experimental and analytical studies. Experimental work will include collecting data on the material properties of the two contacting materials, namely the bulk creep behavior in tension and interfacial creep data in shear. These data will be collected both at room temperature, and at cryogenic temperatures. Interfacial creep takes place when one material is pressed against the other by a constant force and a shear force insufficient to cause gross sliding is applied. The extent to which the bulk creep properties affect the interfacial creep behavior will be determined, and this knowledge will lead to better models of the friction process.

    An intensive survey and testing program of selected segments of a proposed Department of Energy pipeline were conducted by Coastal Environments, Inc., Baton Rouge, Louisiana, during December 1985 and January 1986. The proposed pipeline runs from Texas City, Galveston County to Bryan Mound, Brazoria County. The pedestrian survey was preceded by historical records survey to locate possible historic sites within the DOE righ-of-way. Four prehistoric sites within the ROW (41BO159, 160, 161, 162) and one outside the ROW (41BO163) were located. All are Rangia cuneata middens. The survey results are discussed with particular reference to the environmental settings of the sites and the effectiveness of the survey procedure. Two of the sites located within the ROW were subjected to additional testing. The results of the backhoe testing program are included in the site descriptions, and the scientific value of the sites are presented. 52 refs., 20 figs., 10 tabs.

  10. Evaluation of Water Quality Conditions Near Proposed Fish Production Sites Associated with the Yakima Fisheries Project, 1991-1993 Final Report.

    Energy Technology Data Exchange (ETDEWEB)

    Dauble, Dennis D.

    1994-05-01

    In 1991, the Pacific Northwest Laboratory (PNL) began studying water quality at several sites in the Yakima River Basin for the Bonneville Power Administration. These sites were being proposed as locations for fish culture facilities as part of the Yakima Fisheries Project (YFP). Surface water quality parameters near the proposed fish culture facilities are currently suitable for fish production. Water quality conditions in the mainstream Yakima River and its tributaries are generally excellent in the upper part of the watershed (i.e., near Cle Elum), but they are only fair to poor for the river downstream of Union Gap (river mile 107). Water quality of the Naches River near Oak Flats is also suitable for fish production. Groundwater supplies near the proposed fish production facilities typically have elevated concentrations of metals and dissolved gases. These conditions can be mitigated using best engineering practices such as precipitation and degasification. Additionally, mixing with surface water may improve these conditions. Depending on the location and depth of the well, groundwater temperatures may be warmer than optimum for acclimating and holding juvenile and adult fish. Water quality parameters measured in the Yakima River and tributaries sometimes exceed the range of values described as acceptable for culture of salmonids and for the protection of other aquatic life. However, constituent concentrations are within ranges that exist in many northwest fish hatcheries. Additionally, site-specific tests conducted by PNL (i.e., live box exposures and egg incubation studies) indicate that fish can be successfully reared in surface and well water near the proposed facility sites. Thus, there appear to be no constraints to artificial production for the YFP.

    1980-05-01

    Thirteen spontaneously occurring chlorophyll deficient phenotypes have been described and their genetic basis was established. Ten of these - 'white', 'white tipped green', 'patchy white', 'white virescent', 'white striping 1', 'white striping 2', 'white striping 4', 'fine striping', 'chlorina' and 'yellow virescent' showed monogenic recessive inheritance and the remaining three - 'yellow striping', 'yellow green' and 'light green' seedling phenotypes showed digenic recessive inheritance. The genes for (i) 'white tipped green' (wr) and 'yellow virescent' (yv) and (ii) 'patchy white' (pw) and 'white striping 1' (wst 1) showed independent assortment. Further, the genes for 'white' (w), 'white tipped green' (wr) and 'yellow virescent' (yv) were inherited independently of the gene for hairy leaf margin (Hm).In the mutants - 'white tipped green', 'patchy white', 'white striping 1', 'white striping 2', 'fine striping', 'chlorina', 'yellow virescent', 'yellow striping', 'yellow green' and 'light green' phenotypes total quantity of chlorophyll was significantly less than that in the corresponding controls, while in 'white virescent' there was no reduction in the mature stage. For nine of the mutants the quantity of chlorophyll was also estimated in F1's (mutant x control green). In F1's of six of the mutants - 'white tip', 'patchy white', 'chlorina', 'yellow virescent', 'fine striping' and 'yellow striping' the quantity of chlorophyll was almost equal to the wild type. In the F1's of three of the mutants - 'white striping 1', 'white striping 2' and 'light green' an intermediate value between the mutant and wild types was observed. In 'yellow virescent' retarded synthesis of chlorophyll, particularly chlorophyll a was observed in the juvenile stage. Reduced quantity of chlorophyll was associated with defective chloroplasts. In the mutants - 'white tipped green, 'white virescent', 'fine striping', 'chlorina', 'yellow striping', 'yellow green' and 'light green' defective

  12. Study on the Improvement of Performance of Global Supply Chain Based on Quantity Flexibility Revenue Sharing Contract

    2015-01-01

    The main propose of this study is to manage the demand risk and the exchange rate risk at the same time. Based on a two-echelon decentralized global supply chain,combined with the model equilibrium,this paper studies the difference between the quantity flexibility contract and the revenue sharing contract. By the transmitting of exchange rate risk,it discusses the node-enterprises’ optimal strategies. Hence,it designs a quantity-flexibility-revenue-sharing contract to improve the performance of this global supply chain. The result shows that both the quantity flexibility contract and the revenue sharing contract cause the exchange rate risk to transfer from one enterprise to the other; the exchange rate risk will have different impact on the quantity flexibility contract and the revenue sharing contract because of the difference in the transfer payments at the end of the sales season; by designing a hedging strategy with these two different transfer payments,the quantity-flexibility-revenue-sharing contract can manage the demand risk and the exchange rate risk at the same time.

  13. Defining value through quantity and quality-Chimpanzees (Pan troglodytes) undervalue food quantities when items are broken.

    Decision-making largely is influenced by the relative value of choice options, and the value of such options can be determined by a combination of different factors (e.g., the quantity, size, or quality of a stimulus). In this study, we examined the competing influences of quantity (i.e., the number of food items in a set) and quality (i.e., the original state of a food item) of choice items on chimpanzees' food preferences in a two-option natural choice paradigm. In Experiment 1, chimpanzees chose between sets of food items that were either entirely whole or included items that were broken into pieces before being shown to the chimpanzees. Chimpanzees exhibited a bias for whole food items even when such choice options consisted of a smaller overall quantity of food than the sets containing broken items. In Experiment 2, chimpanzees chose between sets of entirely whole food items and sets of initially whole items that were subsequently broken in view of the chimpanzees just before choice time. Chimpanzees continued to exhibit a bias for sets of whole items. In Experiment 3, chimpanzees chose between sets of new food items that were initially discrete but were subsequently transformed into a larger cohesive unit. Here, chimpanzees were biased to choose the discrete sets that retained their original qualitative state rather than toward the cohesive or clumped sets. These results demonstrate that beyond a food set's quantity (i.e., the value dimension that accounts for maximization in terms of caloric intake), other seemingly non-relevant features (i.e., quality in terms of a set's original state) affect how chimpanzees assign value to their choice options.

  14. Econometric Study of Relationship between Change of Farmland Quantity and Policy of Farmland Protection in China

    2011-01-01

    According to the data from Investigation Report of Land Use Change in China,The Land Resources Communique of China and Chronicle of Statistical Data for Five Decades of New China issued from Ministry of Land Resources,we select two indices:change of farmland quantity and policy of farmland protection.According to econometric theory,by using Eviewes 5.1 software,co-integration analysis,Granger causality test,impulse response and other analysis methods,we analyze the relationship between change of farmland quantity and policy of farmland protection in China since the reform and opening-up.The results show that there is long-term balanced relationship between change of farmland quantity and policy of farmland protection,and there is a certain mechanism restricting motion of variables between the two so as to make the two deviate from each other little and step towards balance in the long run;there is unilateral causality relationship between farmland change and policy of farmland protection,namely that the farmland change is the Granger cause of policy of farmland protection,while policy of farmland protection is not the Granger cause of farmland change;impulse response and variance decomposition indicate that farmland change plays the role of promoting policy of farmland protection continuously,and the role is strengthened along with prolonged lag period;the policy of farmland protection has strong inertia,because it is impacted by the former level of itself,and the policy of farmland protection plays insignificant role in promoting farmland quantity.Consequently,the important approach of solving problem of rapid decrease of farmland is to formulate long-term strategy,strengthen theoretical research of farmland protection and reinforce degree of formulation,implementation and surveillance of farmland protection policy.

    Periodontal diseases are common and their prevalence varies in different populations. However, prevalence estimates are influenced by the methodology used, including measurement techniques, case definitions, and periodontal examination protocols, as well as differences in oral health status. As a consequence, comparisons between populations are severely hampered and inferences regarding the global variation in prevalence can hardly be drawn. To overcome these limitations, the authors suggest standardized principles for the reporting of the prevalence and severity of periodontal diseases in future epidemiological studies. These principles include the comprehensive reporting of the study design, the recording protocol, and specific subject-related and oral data. Further, a range of periodontal data should be reported in the total population and within specific age groups. Periodontal data include the prevalence and extent of clinical attachment loss (CAL) and probing depth (PD) on site and tooth level according to specific thresholds, mean CAL/PD, the CDC/AAP case definition, and bleeding on probing. Consistent implementation of these standards in future studies will ensure improved reporting quality, permit meaningful comparisons of the prevalence of periodontal diseases across populations, and provide better insights into the determinants of such variation.

    1997-03-01

    This report documents the development of major energy-related programs at the Los Alamos Scientific Laboratory between 1945 and 1979. Although the Laboratory`s primary mission during that era was the design and development of nuclear weapons and most of the Laboratory`s funding came from a single source, a number of factors were at work that led to the development of these other programs. Some of those factors were affected by the Laboratory`s internal management structure and organization; others were the result of increasing environmental awareness within the general population and the political consequences of that awareness; still others were related to the increasing demand for energy and the increasing turmoil in the energy-rich Middle East. This report also describes the various activities in Los Alamos, in Washington, and in other areas of the world that contributed to the development of major energy-related programs at Los Alamos. The author has a unique historical perspective because of his involvement as a scientist and manager at the Los Alamos Scientific Laboratory during the time period described within the report. In addition, in numerous footnotes and references, he cites a large body of documents that include the opinions and perspectives of many others who were involved at one time or another in these programs. Finally the report includes a detailed chronology of geopolitical events that led to the development of energy-related programs at Los Alamos.

    The aim of this study was to design a checklist with a scoring system for reporting on studies of surgical interventions for trigeminal neuralgia (TN) and to validate it by a review of the recent literature. A checklist with a scoring system, the Surgical Trigeminal Neuralgia Score (STNS), was devised partially based on the validated STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) criteria and customized for TN after a literature review and then applied to a series of articles. These articles were identified using a prespecified MEDLINE and Embase search covering the period from 2008 to 2010. Of the 584 articles found, 59 were studies of interventional procedures for TN that fulfilled the inclusion criteria and 56 could be obtained in full. The STNS was then applied independently by 3 of the authors. The maximum STNS came to 30, and was reliable and reproducible when used by the 3 authors who performed the scoring. The range of scores was 6-23.5, with a mean of 14 for all the journals. The impact factor scores of the journals in which the papers were published ranged from 0 to 4.8. Twenty-four of the studies were published in the Journal of Neurosurgery or in Neurosurgery. Studies published in neurosurgical journals ranked higher on the STNS scale than those published in nonneurosurgical journals. There was no statistically significant correlation between STNS and impact factors. Stereotactic radiosurgery (n = 25) and microvascular decompression (n = 15) were the most commonly reported procedures. The diagnostic criteria were stated in 35% of the studies, and 4 studies reported subtypes of TN. An increasing number of studies (46%) used the recommended Kaplan-Meier methodology for pain survival outcomes. The follow-up period was unclear in 8 studies, and 26 reported follow-ups of more than 5 years. Complications were reported fairly consistently but the temporal course was not always indicated.

    To assess the relative, independent contribution of reported tobacco-specific media exposure (pro-tobacco advertising, anti-tobacco advertising, and news coverage of tobacco issues) to US adults' support for policy efforts that aim to regulate the portrayal of smoking in movies. Using the American Legacy Foundation's 2003 American Smoking and Health Survey (ASHES-2), multivariable logistic regression was used to model the predicted probability that US adults support movie-specific tobacco control policies, by reported exposure to tobacco-specific media messages, controlling for smoking status, education, income, race/ethnicity, age, sex, knowledge of the negative effects of tobacco and state. Across most outcome variables under study, findings reveal that reported exposure to tobacco-specific media messages is associated with adult attitudes towards movie-specific policy measures. Most exposure to tobacco information in the media (with the exception of pro-tobacco advertising on the internet) contributes independently to the prediction of adult support for movie-specific policies. The direction of effect follows an expected pattern, with reported exposure to anti-tobacco advertising and news coverage of tobacco predicting supportive attitudes towards movie policies, and reported exposure to pro-tobacco advertising lessening support for some movie policies, though the medium of delivery makes a difference. Media campaigns to prevent tobacco use and exposure to secondhand smoke have had value beyond the intended impact of single-issue campaigns; exposure to anti-tobacco campaigns and public dialogue about the dangers of tobacco seem also to be associated with shaping perceptions of the social world related to norms about tobacco, and ideas about regulating the portrayal of smoking in movies.

    1987-09-01

    The purposes of this study were to assess the effect of two quantities (1 mL or 3 mL) of four different handwashing products on reductions in log colony-forming units (CFU) from the hands and to determine the amount of liquid soap used for handwashing by personnel in one hospital. First, 40 subjects were assigned by block randomization to one of four handwashing products (4% chlorhexidine gluconate in a detergent base, two alcohol hand rinses, and a liquid, nonantimicrobial soap) to be used in either 1 mL or 3 mL amounts per wash. Each subject washed his or her hands 15 times per day for five days. After one and five days of handwashing there were significant reductions over baseline in log CFU between handwashing products (P less than 0.001). Additionally, subjects using 3 mL of antiseptic soap had significantly greater reductions in log CFU than those using 1 mL (P less than 0.001). Among subjects using control liquid soap there was no such dose response. Second, a survey of 47 members of a hospital nursing staff from nine specialty areas and ten individuals in the general population was conducted to measure amounts of two liquid soaps used for handwashing. Amount of soap ranged from 0.4 to 9 mL per handwash. Personnel working in clinical areas where patients were at high risk for nosocomial infection used significantly more soap than did others (P less than 0.05). We conclude that quantity of soap used for handwashing is one variable influencing the microbial counts on hands, and that the quantity of soap used by health care personnel varies considerably.

    Identifying and capitalizing on shared professional values, health-care professionals have the potential to promote collaboration and facilitate enhanced patient outcomes. This paper describes a qualitative study that sought to identify values shared among health-care professionals through the development of an interprofessional health-care provider oath. Core competencies for collaborative practice of all health-care workers were delineated by the recent report from the Interprofessional Education Collaborative Expert Panel and these include values and ethics of collaboration as well as an understanding of team roles. This proposed interprofessional oath was developed from a qualitative analysis of oaths developed by interprofessional teams of health-care students. Using Colaizzi's method, 18 oaths were evaluated to identify significant statements, formulated meanings, and themes. A proposed interprofessional oath was developed based on these elements and is offered for consideration along with discussion of the potential benefits and challenges of an interprofessional oath.

    2015-01-01

    Based on some ideas emerged from the classical Kaluza-Klein theory, we present a $5D$ universe as a product bundle over the $4D$ spacetime. This enables us to introduce and study two categories of kinematic quantities (expansions, shear, vorticity) in a $5D$ universe. One category is related to the fourth dimension (time), and the other one comes from the assumption of the existence of the fifth dimension. The Raychaudhuri type equations that we obtain in the paper, lead us to results on the evolution of both the $4D$ expansion and $5D$ expansion in a $5D$ universe.

    We study the thermodynamic quantities such as the Helmholtz free energy, the mean energy and the specific heat for both the Klein-Gordon, and Dirac equations. Our analyze includes two main subsections: (1) statistical functions for the Klein-Gordon equation with a linear potential having Lorentz vector, and Lorentz scalar parts (2) thermodynamic functions for the Dirac equation with a Lorentz scalar, inverse-linear potential by assuming that the scalar potential field is strong ( A ≫ 1). We restrict ourselves to the case where only the positive part of the spectrum gives a contribution to the sum in partition function. We give the analytical results for high temperatures.

  11. A horizontal mobile measuring system for atmospheric quantities

    Directory of Open Access Journals (Sweden)

    J. Hübner

    2014-05-01

    Full Text Available A fully automatic Horizontal Mobile Measuring System (HMMS for atmospheric quantities has been developed. The HMMS is based on the drive mechanism of a garden railway system and can be installed at any location and with any measuring track. In addition to meteorological quantities (temperature, humidity and short/long-wave down/upwelling radiation, HMMS also measures trace gas concentrations (carbon dioxide and ozone. While sufficient spatial resolution is a problem even for measurements on distributed towers, this could be easily achieved with the HMMS, which has been specifically developed to obtain higher information density about horizontal gradients in a heterogeneous forest ecosystem. There, horizontal gradients of meteorological quantities and trace gases could be immense, particularly at the transition from a dense forest to an open clearing, with large impact on meteorological parameters and exchange processes. Consequently, HMMS was firstly applied during EGER IOP3 project (ExchanGE processes in mountainous Regions – Intense Observation Period 3 in the Fichtelgebirge Mountains (SE Germany during summer 2011. At a constant 1 m above ground, the measuring track of the HMMS consisted of a straight line perpendicular to the forest edge, starting in the dense spruce forest and leading 75 m into an open clearing. Tags with bar codes, mounted every meter on the wooden substructure, allowed (a keeping the speed of the HMMS constant (approx. 0.5 m s−1 and (b operation of the HMMS in a continuous back and forth running mode. During EGER IOP3, HMMS was operational for almost 250 h. Results show that – due to considerably long response times (between 4 s and 20 s of commercial temperature, humidity and the radiation sensors – true spatial variations of the meteorological quantities could not be adequately captured (mainly at the forest edge. Corresponding dynamical (spatial errors of the measurement values were corrected on the basis of

    In the context of the teleparallel equivalent of general relativity (TEGR) theory, continues calculations of the total energy and momentum for Kerr-NUT spacetimes using three different methods, the gravitational energy-momentum, the Riemannian connection 1-form, ${\\widetilde{\\Gamma}_\\alpha}^\\beta$ and the Euclidean continuation method, have been achieved. Many local Lorentz transformations, that play the role of regularizing tool, are given to get the commonly known form of energy and momentum. We calculate the thermodynamic quantities of Kerr-NUT spacetime. We also investigate the first law of thermodynamics and quantum statistical relation.

    Because of the proximity of the oropharynx (a naturally contaminated region) to the spinal structures of the craniocervical junction, it is possible that small mucosal lacerations in the oropharynx caused by unstable traumatic craniocervical injuries may become contaminated and lead to secondary infection and osteomyelitis. In this report, the authors describe the case of a previously healthy and immunocompetent patient who developed a large retropharyngeal abscess with spinal osteomyelitis after a high-energy craniocervical injury. This unusual report of osteomyelitis with a delayed presentation after a high-energy traumatic injury of the craniocervical junction highlights the possibility of direct injury to a specific area in the oropharyngeal mucosa adjacent to the osteoligamentous structures of the craniocervical junction, an overall underrecognized complication of unstable craniocervical injuries.

    Utility under uncertainty is a field of decision theory that has received increasing attention in the field of health. The report reviews its uses during the past decade and suggests its possible use in national air quality standard setting procedures. It is common practice in standard setting to assess the likelihood of air pollution effects on sensitive populations. One such poplation, asthmatics, is selected in the report and the relationship between air pollution and asthma is reviewed. In addition, three possible pilot studies are suggested which use aspects of utility under uncertainty theory to elicit values concerning asthma health effects. The results of such studies would provide the US EPA with information for their ambient air quality standard setting and increase the awareness of the possible uses of utility theory in such applications.

    2013-07-01

    Nevus of Ota and nevus of Ito are rare dermal melanocytoses. Nevus of Ota may be very rarely associated with the nevus of Ito and other extra cutaneous features. Both nevi are similar in all respect apart from the area of distribution. Bilateral distribution of nevus of Ito is seldom reported in the literature. A 24-year-old male patient reported with nevus of Ota of the right side of his face since his infancy and nevus of Ito on both shoulder regions since early childhood. He had bluish lesions on the right side of his hard palate. Systemic examination was normal. Relevant laboratory investigations were non contributory. The histopathological examination of the skin from the affected areas showed the presence of elongated dendritic dermal melanocytes. The present case is the first report of an association of bilateral nevus of Ito with nevus of Ota and palatal lesions. Tanino classified Nevus of Ota into four groups. As both the nevi are similar in all respect except the area of distribution, a minor modification of the existing Tanino's classification to incorporate the nevus of Ito into the classification for the Ota's nevus may be appropriate.

    A method using a hydrogen arc for synthesizing large quantities of carbon nanotubes filled with pure copper is reported. The interaction of small copper clusters with polycyclic aromatic hydrocarbons (PAHs) is shown to form carbon nanotubes and encapsulated copper nanowires. The effectiveness of this model is demonstrated by showing that no copper filled nanotubes are formed in a helium arc that does not generate PAHs. A direct proof of this model is demonstrated by using pyrene, a PAH molecule, to grow carbon nanotubes and encapsulated copper nanowires.

    1996-06-01

    This technical report is a comprehensive evaluation of the proposal by the Ukrainian State Committee on Nuclear Power Utilization to create a central facility for radioactive waste (not spent fuel) processing. The central facility is intended to process liquid and solid radioactive wastes generated from all of the Ukrainian nuclear power plants and the waste generated as a result of Chernobyl 1, 2 and 3 decommissioning efforts. In addition, this report provides general information on the quantity and total activity of radioactive waste in the 30-km Zone and the Sarcophagus from the Chernobyl accident. Processing options are described that may ultimately be used in the long-term disposal of selected 30-km Zone and Sarcophagus wastes. A detailed report on the issues concerning the construction of a Ukrainian Central Radioactive Waste Processing Facility (CRWPF) from the Ukrainian Scientific Research and Design institute for Industrial Technology was obtained and incorporated into this report. This report outlines various processing options, their associated costs and construction schedules, which can be applied to solving the operating and decommissioning radioactive waste management problems in Ukraine. The costs and schedules are best estimates based upon the most current US industry practice and vendor information. This report focuses primarily on the handling and processing of what is defined in the US as low-level radioactive wastes.

    Full Text Available To eliminate health and environmental problems caused by using conventional cutting fluid in the metal cutting industry, a new economical and practical approach to minimum quantity of lubrication machining technique is developed. Turning is a widely used metal removal process in manufacturing industry that involves generation of high cutting forces and temperature. Lubrication becomes critical to minimize the effects of these forces and temperature on cutting tool and work piece. Strained environment is a global problem. In metalcutting industry the use of coolant has become more problematic in terms of both employee health and environmental pollution. It is said that the use of coolant forms approximately 8-16 % of the total production costs. Development of lubricants that is eco-friendly and economically is acquiring importance. In this context, using minimum quantity of lubrication of boric acid mixed with base oil SAE 40 has proved to be a feasible alternative to the conventional cutting fluid. In the present work 10% boric acid by weight mixed with base oil SAE 40 is used as a MQL in turning process. Variations in cutting (lubricant force, cutting temp, chip thickness and surface roughness are studied under different machining conditions. The results indicate that there is a considerable improvement in machining performance with MQL assisted machining compared to dry machining.

    Objective: aiming at contributing to the knowledge on doses in computed tomography (CT), this study has the objective of determining dosimetric quantities associated with pediatric abdominal CT scans, comparing the data with diagnostic reference levels (DRL). Materials and methods: the study was developed with a Toshiba Asteion single-slice CT scanner and a GE BrightSpeed multi-slice CT unit in two hospitals. Measurements were performed with a pencil-type ionization chamber and a 16 cm-diameter polymethylmethacrylate trunk phantom. Results: No significant difference was observed in the values for weighted air kerma index (C{sub W}), but the differences were relevant in values for volumetric air kerma index (C{sub VOL}), air kerma-length product (P{sub KL,CT}) and effective dose. Conclusion: Only the CW values were lower than the DRL, suggesting that dose optimization might not be necessary. However, P{sub KL,CT} and effective dose values stressed that there still is room for reducing pediatric radiation doses. The present study emphasizes the importance of determining all dosimetric quantities associated with CT scans. (author)

Over the past decade thedegree course has been constantly upgraded and altered inline with recommendations from professional bodies such asthese and other industry partners. In 1994 the Departmentof Building and Construction Economics re-assesseda range of subjects including the first year technologysubjects. Out of the review a problem-based integratedlearning unit was developed and tested. This unit has nowbeen in place for ten years.Quantity surveying and construction management likemost other professions in the construction industryrequire teamwork and advanced consultation skills. Theseskills may be learnt through experience but there isconsiderable evidence that these skills can be taught in theundergraduate years. Therefore in line with team-basedapproaches used in industry and professional constructionsettings, this year a new assessment model - peerassessment - will be applied to the problem-based learningunit. This paper describes the procedures and processesused to introduce the change and examines the theoreticalbase upon which the model was developed.

  6. Oscillatory brain activity reveals linguistic prints in the quantity code.

    Directory of Open Access Journals (Sweden)

    Elena Salillas

    Full Text Available Number representations change through education, although it is currently unclear whether and how language could impact the magnitude representation that we share with other species. The most prominent view is that language does not play any role in modulating the core numeric representation involved in the contrast of quantities. Nevertheless, possible cultural hints on the numerical magnitude representation are currently on discussion focus. In fact, the acquisition of number words provides linguistic input that the quantity system may not ignore. Bilingualism offers a window to the study of this question, especially in bilinguals where the two number wording systems imply also two different numerical systems, such as in Basque-Spanish bilinguals. The present study evidences linguistic prints in the core number representational system through the analysis of EEG oscillatory activity during a simple number comparison task. Gamma band synchronization appears when Basque-Spanish bilinguals compare pairs of Arabic numbers linked through the Basque base-20 wording system, but it does not if the pairs are related through the base-10 system. Crucially, this gamma activity, originated in a left fronto-parietal network, only appears in bilinguals who learned math in Basque and not in equivalent proficiency bilinguals who learned math in Spanish. Thus, this neural index reflected in gamma band synchrony appears to be triggered by early learning experience with the base-20 numerical associations in Basque number words.

  7. Determinants of procurement strategy for construction works: quantity surveyors’ perspectives

    2016-01-01

    Full Text Available The selection of the ‘appropriate’ procurement strategy is a prerequisite to the success or failure of a construction project. This paper investigates the factors determining the selection of appropriate procurement strategy for construction works in Nigeria. Data for the study was collected through an online survey questionnaire. The survey administration involves only quantity surveyors. Quantity surveyors were targeted because they advise clients and other stakeholders on procurement and contractual issues on construction works. A total of 33 usable responses were received and analysed for this study. On the basis of the results, it is concluded that the selection of procurement strategies for construction depend on complex interrelated factors. The study could not detect a particular factor or few factors responsible for a procurement strategy selection. The findings of this study is useful because it argues that the construction sector needs to broaden its considerations on the procurement strategy’s determinants rather than focusing solely on the client’s type and nature of projects as is often cited. Future research could segment these factors in terms of class of construction works or increase the sample size, which might lead to different findings.

  8. The effects of quantum gravity on some thermodynamical quantities

    Kamali, A. D.; Shababi, H.; Nozari, K.

    2016-10-01

    In this paper, using a deformed algebra [X,P] = iℏ/(1 - α2P2) which is originated from various theories of gravity, we study thermodynamical properties of the classical and extreme relativistic gases in canonical ensembles. In this regards, we exactly calculate the modified partition function, Helmholtz free energy, internal energy, entropy, heat capacity and the thermal pressure which conclude to the familiar form of the equation of state for the ideal gas. The advantage of applying this algebra is not only considering all natural cutoffs but also its structure is similar to the other effective quantum gravity models such as polymer, Snyder and noncommutative space-time frameworks. Moreover, after obtaining some thermodynamical quantities including internal energy and entropy, we conclude at high temperature limits due to the decreasing of the number of microstates, these quantities reach to maximal bounds which do not exist in standard cases and it concludes that at the presence of gravity for both micro-canonic and canonic ensembles, the internal energy and the entropy tend to these upper bounds.

    2017-09-01

    In the nuclear tunneling processes involving deformed nuclei, most of the tunneling-related quantities depend on the relative orientations of the participating nuclei. In the presence of different multipole deformations, we study the variation of a few relevant quantities for the α-decay and the sub-barrier fusion processes, in an orientation degree of freedom. The knocking frequency and the penetration probability are evaluated within the Wentzel-Kramers-Brillouin approximation. The interaction potential is calculated with Skyrme-type nucleon-nucleon interaction. We found that the width of the potential pocket, the Coulomb barrier radius, the penetration probability, the α-decay width, and the fusion cross-section follow consistently the orientation-angle variation of the radius of the deformed nucleus. The orientation distribution patterns of the pocket width, the barrier radius, the logarithms of the penetrability, the decay width, and the fusion cross-section are found to be highly analogous to pattern of the deformed-nucleus radius. The curve patterns of the orientation angle distributions of the internal pocket depth, the Coulomb barrier height and width, as well as the knocking frequency simulate inversely the variation of the deformed nucleus radius. The predicted orientation behaviors will be of a special interest in predicting the optimum orientations for the tunneling processes.

    1989-01-31

    The TRW site is a Proposed National Priorities List (NPL) site located about one mile northeast of downtown Minerva, Stark County, Ohio. Previous disposal practices by the former TRW plant (currently owned by PCC Airfoils, Inc.) introduced polychlorinated biphenyls (PCBs) and volatile organic compounds (VOCs) into on-site and off-site soils and ground water. Off-site residential wells were contaminated with elevated levels of VOCs, especially vinyl chloride. In 1985, contaminated soils and sediments from the former disposal areas were excavated and disposed of in an on-site secure landfill (cell). In addition, in 1986 a Consent Order between TRW and the Ohio Environmental Protection Agency was signed, in which TRW agreed to implement an on-site and off-site ground water 'pump and treat' operation to intercept the VOC contaminant plumes. The site is of potential public health concern because of the risk to human health that could result from possible exposure to hazardous substances at levels that may result in adverse health effects over time.

  13. A proposed framework for establishing integrated cost and performance criteria for environmental technologies. A summary report to the U.S. Department of Energy

    Energy Technology Data Exchange (ETDEWEB)

    1994-05-01

    Through an Interagency Agreement between the US Environmental Protection Agency (EPA) and the US Department of Energy (DOE), EPA directed a project to establish a suite of standard cost and performance criteria to guide the evaluation of environmental cleanup technologies for DOE sites. Ideally, these criteria would be ``generic`` in that they could be used as a basis for evaluating any cleanup technology for any DOE site. To be most useful, however, these criteria would also reflect the interests of diverse decisionmakers who influence DOE technology evaluation. The project was conducted by the National Environmental Technology Applications Center (NETAC), a nonprofit organization specializing in the development and commercialization of new and innovative environmental technologies for national and international markets. To accomplish the project objective, NETAC (1) developed a data gathering questionnaire, (2) interviewed government and industry decisionmakers, (3) identified previous criteria development efforts, (4) conducted a workshop, (5) evaluated workshop discussions, and (6) applied its five years` experience in commercializing environmental technologies to analyze project findings. The project resulted in the development of a unique and comprehensive resource or tool to enhance communication among decisionmakers. This resource, a ``Proposed Framework for Establishing Integrated Cost and Performance Criteria for Evaluating Environmental Cleanup Technologies for DOE Sites,`` offers decisionmakers a first-time comprehensive assessment of major technology evaluation issues by a decisionmaker group.

    This annual report describes the first year's accomplishments under the NERI2000-109 project. We present a model-independent approach to quantify changes in the nonlinear dynamics underlying time-serial data. From time-windowed data sets, we construct discrete distribution functions on the phase space. Condition change between base case and test case distribution functions is assessed by dissimilarity measures via L{sub 1}-distance and {chi}{sup 2} statistic. The discriminating power of these measures is first tested on noiseless model data, and then applied for detecting dynamical change in power from a motor-pump system. We compare the phase-space dissimilarities with traditional linear and nonlinear measures used in the analysis of chaotic systems. We also assess the potential usefulness of the new measures for robust, accurate, and timely forewarning of equipment failure.

    ABC inventory analysis and the economic order quantity (EOQ) concept were studied as alternatives to the cyclical ordering system used by the pharmacy in a 558-bed general hospital. The inventory was divided into A, B or C groups according to the annual dollar value of the items. Two samples were selected to be studied (the first consisting of 10% of the total inventory and the second consisting of 10% of the A, or high cost, items). For each item in both samples the EOQ was calculated to estimate the proposed annual inventory cost as compared to the actual cost as determined from past inventory records. In the first sample, there was a statistically significant mean annual savings of $4.13 +/- $0.36 (S.E.) using the proposed annual cost. In the second sample there was a mean savings of $2.42 +/- $0.60 (S.E.) using the proposed method, which was not statistically significant. Most of the savings with the proposed ABC-EOQ system would occur with the low dollar value items (B and C items) which were being purchased too frequently.

    2011-09-01

    Full Text Available Introduction: The role played by minimum quantities, generating large scale effects, and even of catastrophic consequence, is very commonly observed in many areas of science. In Physics, for example, the doping of impurities in materials like silicon (as low as one atom per billion results in spectacular semiconductor properties. In Biology, the effects of pheromones produced by insects and other animals are so dramatic that females of the emperor moth can attract mating males from kilometers away. And, concerning human health, severe body reactions may occur following the ingestion of very diminutive quantity of some allergic food. In this paper, the question of how Nature provides mechanisms for developing such dramatic and many times unexpected results, from very faint stimulus, will be proposed and discussed. In particular, a model for the controversial issue of how homeopathic remedies can influence and impose organic responses will also be addressed. This model particularly rely on the here named infotrans mechanism, which is based on a type of resonant property that may induce living organisms to promptly over-react after a pseudo environmental aggression. Finally, arguments will be provided to demonstrate that water, mainly due to its very high dielectric constant, can be considered a very good mediator for the infotrans. The Role of Water in Important Biological Mechanisms: Assuming that water molecules can indeed rearrange themselves to form larger clusters, it is reasonable to accept that different external excitations might induce these structures to assemble in distinctive ways. As matter of fact, experimental evidences already exist in literature showing that ultra-high dilutions of different substances, when compared to pure water, do exhibit relevant physico-chemical differences. More recently, investigations have shown that water plays a crucial role in biological systems such as the protein folding process or the twisting

    Full Text Available Background: In this paper, an economic production quantity model is considered under a fuzzy environment. Both the demand cost and holding cost are considered using fuzzy pentagonal numbers. The Signed Distance Method is used to defuzzify the total cost function. Methods: The results obtained by these methods are compared with the help of a numerical example. Sensitivity analysis is also carried out to explore the effect of changes in the values of some of the system parameters. Results and conclusions: The fuzzy EPQ model with time dependent demand rate was presented together with the possible implementation. The behavior of changes in parameters was analyzed. The possible extension of the implementation of this method was presented.

  1. Evidence for a Conserved Quantity in Human Mobility

    Faced with effectively unlimited choices of how to spend their time, humans are constantly balancing a trade-off between exploitation of familiar places and exploration of new locations. Previous analyses have shown that at the daily and weekly timescales individuals are well characterized by an activity space of repeatedly visited locations. How this activity space evolves in time, however, remains unexplored. Here we analyse high-resolution spatio-temporal traces from 850 individuals participating in a 24-month experiment. We find that, although activity spaces undergo considerable changes, the number of familiar locations an individual visits at any point in time is a conserved quantity. We show that this number is similar for different individuals, revealing a substantial homogeneity of the observed population. We point out that the observed fixed size of the activity space cannot be explained in terms of time constraints, and is therefore a distinctive property of human behavior.

    Scattering and transition amplitudes with three-hadron final states play an important role in nuclear and particle physics. However, predicting such quantities using numerical Lattice QCD is very difficult, in part because of the effects of Euclidean time and finite volume. In this review we highlight recent formal developments that work towards overcoming these issues. We organize the presentation into three parts: large volume expansions, non-relativistic nonperturbative analyses, and nonperturbative studies based in relativistic field theory. In the first part we discuss results for ground state energies and matrix elements given by expanding in inverse box length, $1/L$. We describe complications that arise at $\\mathcal O(1/L^6)$ and include a table summarizing the results of different calculations. In the second part we summarize three recent non-relativistic non-perturbative studies and highlight the main conclusions of these works. This includes demonstrating that the three-particle finite-volume spect...

    The use of green roofs is gaining increased recognition in many countries as a solution that can be used to improve environmental quality and reduce runoff quantity. To achieve these goals, pilot-scale green roof assemblies have been constructed and operated in an urban setting. From a stormwater management perspective, green roofs are 42.8-60.8% effective in reducing runoff for 200 mm soil depth and 13.8-34.4% effective in reducing runoff for 150 mm soil depth. By using Spearman rank correlation analysis, high rainfall intensity was shown to have a negative relationship with delayed occurrence time, demonstrating that the soil media in green roofs do not efficiently retain rainwater. Increasing the number of antecedent dry days can help to improve water retention capacity and delay occurrence time. From the viewpoint of runoff water quality, green roofs are regarded as the best management practice by filtration and adsorption through growth media (soil).

  5. A Quantities Method of Induction Motor Under Unbalanced Voltage Conditions

    2010-08-01

    Full Text Available The most complete definition for the voltage unbalance is using complex voltage unbalance factor (CVUF that consists of its magnitude and angle. Unfortunately, the definition did not distinguish between undervoltage and overvoltage unbalance conditions. In this paper, the analysis of the motor is performed using the method of symmetrical component and MATLAB software is used to investigate the performance of induction motor. The simulation results show that the International Electrotechnical Commission (IEC definition of the voltage unbalance can be applied to evaluate total copper losses precisely. However, the phase angle of unbalance factor must be included for accurate predicting of peak currents and peak copper losses of the phase windings of the motor.The unbalanced conditions which distinguish between under and over voltage unbalance must also be taken into consideration for assessing all the quantities.

    We are taught that gauge transformations in classical and quantum mechanics do not change the physics of the problem. Nevertheless, here we discuss three broad scenarios where under gauge transformations: (i) conservation laws are not preserved in the usual manner; (ii) non-gauge-invariant quantities can be associated with physical observables; and (iii) there are changes in the physical boundary conditions of the wave function that render it non-single-valued. We give worked examples that illustrate these points, in contrast to general opinions from classic texts. We also give a historical perspective on the development of Abelian gauge theory in relation to our particular points. Our aim is to provide a discussion of these issues at the graduate level.

  7. Quantity and structure of word knowledge across adulthood.

    Science.gov (United States)

    Salthouse, Timothy A

    2014-09-01

    Cross-sectional and longitudinal data from moderately large samples of healthy adults confirmed prior findings of age-related declines in measures of the quantity of word knowledge beginning around age 65. Additional analyses were carried out to investigate the interrelations of different types of vocabulary knowledge at various periods in adulthood. Although the organizational structures were similar in adults of different ages, scores on tests with different formats had weaker relations to a higher-order vocabulary construct beginning when adults were in their 60's. The within-person dispersion among different vocabulary test scores was also greater after about 65 years of age. The discovery of quantitative decreases in amount of knowledge occurring at about the same age as qualitative shifts in the structure of knowledge raises the possibility that the two types of changes may be causally linked.

    Two results support the idea that the scalar and vector potentials in the Lorenz gauge can be considered to be physical quantities: (i) they separately satisfy the properties of causality and propagation at the speed of light and do not imply spurious terms and (ii) they can naturally be written in a manifestly covariant form. In this paper we introduce expressions for the Lorenz-gauge potentials: at the present time in terms of electric and magnetic fields at the retarded time. These expressions provide a third result in favour of a physical interpretation of the Lorenz-gauge potentials: (iii) they can be regarded as causal effects of the observed electric and magnetic fields.

  9. How to Combine Independent Data Sets for the Same Quantity

    Fox, Ronald F; Miller, Jack

    2010-01-01

    This paper describes a recent mathematical method called conflation for consolidating data from independent experiments that are designed to measure the same quantity, such as Planck's constant or the mass of the top quark. Conflation is easy to calculate and visualize, and minimizes the maximum loss in Shannon information in consolidating several independent distributions into a single distribution. In order to benefit the experimentalist with a much more transparent presentation than the previous mathematical treatise, the main basic properties of conflation are derived in the special case of normal (Gaussian) data. Included are examples of applications to real data from measurements of the fundamental physical constants and from measurements in high energy physics, and the conflation operation is generalized to weighted conflation for situations when the underlying experiments are not uniformly reliable.

    The European Commission announced in 2008 that a fundamental revision of the medical device directives is being considered in order to clarify and strengthen the current legal framework. The system for testing and approving devices in Europe was established >20 years ago as a 'New Approach' to a previously little-regulated industry. It is recognized by many that the regulatory system has not kept pace with technological advances and changing patterns of medical practice. New legislation will be drafted during 2011, but medical experts have been little involved in this important process. This context makes it an opportune time for a professional association to advise from both clinical and academic perspectives about changes which should be made to improve the safety and efficacy of devices used in clinical practice and to develop more appropriate systems for their clinical evaluation and post-marketing surveillance. This report summarizes how medical devices are regulated and it reviews some serious clinical problems that have occurred with cardiovascular devices. Finally, it presents the main recommendations from a Policy Conference on the Clinical Evaluation of Cardiovascular Devices that was held at the European Heart House in January 2011.

    Mating has profound effects on the physiology and behavior of female insects, and in honey bee (Apis mellifera) queens, these changes are permanent. Queens mate with multiple males during a brief period in their early adult lives, and shortly thereafter they initiate egg-laying. Furthermore, the pheromone profiles of mated queens differ from those of virgins, and these pheromones regulate many different aspects of worker behavior and colony organization. While it is clear that mating causes dramatic changes in queens, it is unclear if mating number has more subtle effects on queen physiology or queen-worker interactions; indeed, the effect of multiple matings on female insect physiology has not been broadly addressed. Because it is not possible to control the natural mating behavior of queens, we used instrumental insemination and compared queens inseminated with semen from either a single drone (single-drone inseminated, or SDI) or 10 drones (multi-drone inseminated, or MDI). We used observation hives to monitor attraction of workers to SDI or MDI queens in colonies, and cage studies to monitor the attraction of workers to virgin, SDI, and MDI queen mandibular gland extracts (the main source of queen pheromone). The chemical profiles of the mandibular glands of virgin, SDI, and MDI queens were characterized using GC-MS. Finally, we measured brain expression levels in SDI and MDI queens of a gene associated with phototaxis in worker honey bees (Amfor). Here, we demonstrate for the first time that insemination quantity significantly affects mandibular gland chemical profiles, queen-worker interactions, and brain gene expression. Further research will be necessary to elucidate the mechanistic bases for these effects: insemination volume, sperm and seminal protein quantity, and genetic diversity of the sperm may all be important factors contributing to this profound change in honey bee queen physiology, queen behavior, and social interactions in the colony.

    Infertility is an important health issue which has been neglected in the developing countries. First test-tube babies (triplet) in Bangladesh were born on 30th May, 2001. Although there is no tertiary level infertility center in the public sector, several private centers have come up with the facilities. The objective of the study was to find i) the quality and quantity of infertility care in Bangladesh and ii) the cause of infertility in the attending patients iii) the treatment seeking behaviors iv) and the reasons for not taking treatment among the attending patients. There are now 10 tertiary level Infertility centers in Bangladesh. The information was collected in a preformed datasheet about the facilities and the profile of the patients and the treatment seeking behavior of the attending patients. Out of the ten centers two centers refused to respond and did not disclose their data. Around 16700 new patients are enrolled in a year in the responsive clinics. Five percent (5%) of the patients underwent ART, 7% of the patients gave only one visit, 84% of the patients completed their evaluation, 76% of the patients took treatment. Causes of infertility in the patients taking treatment were male factor in 36.4%, bilateral tubal block in 20.2%, PCOS and anovulation in 31.7%, endometriosis in 19.6%, unexplained in 10.95, combined in 3.5%, ovarian failure in 1.4%, testicular failure in 0.33%, congenital anomaly in 0.3%. The main reason for not taking treatment was financial constrainment. The quality and quantity of infertility care is dependent on the available resources and on the use of the resources by the patients. In developing countries the resources are merging and confined to specified areas which cannot meet the demand of their population. The study gives us the idea of the need and the demand of the services in the country.

  14. Suggestions for revised definitions of noise quantities, including quantum effects

    Kerr, A. R.

    1999-03-01

    Recent advances in millimeter- and submillimeter-wavelength receivers and the development of low-noise optical amplifiers focus attention on inconsistencies and ambiguities in the standard definitions of noise quantities and the procedures for measuring them. The difficulty is caused by the zero-point (quantum) noise hf/2 W/Hz, which is present even at absolute zero temperature, and also by the nonlinear dependence at low temperature of the thermal noise power of a resistor on its physical temperature, as given by the Planck law. Until recently, these effects were insignificant in all but the most exotic experiments, and the familiar Rayleigh-Jeans noise formula P=kT W/Hz could safely be used in most situations, Now, particularly in low-noise millimeter-wave and photonic devices, the quantum noise is prominent and the nonlinearity of the Planck law can no longer be neglected. The IEEE Standard Dictionary of Electrical and Electronics Terms gives several definitions of the noise temperature of a resistor or a port, which include: 1) the physical temperature of the resistor and 2) its available noise power density divided by Boltzmann's constant-definitions which are incompatible because of the nature of the Planck radiation law. In addition, there is no indication of whether the zero-point noise should be included as part of the noise temperature. Revised definitions of the common noise quantities are suggested, which resolve the shortcomings of the present definitions. The revised definitions have only a small effect on most RF and microwave measurements, but they provide a common consistent noise terminology from dc to light frequencies.

    Full Text Available Funded within the European Metrology Research Programme (EMRP [1], the joint research project “Biologically weighted quantities in radiotherapy” (BioQuaRT [2] aims to develop measurement and simulation techniques for determining the physical properties of ionising particle tracks on different length scales (about 2 nm to 10 μm, and to investigate the correlation of these track structure characteristics with the biological effects of radiation at the cellular level. Work package 1 develops micro-calorimeter prototypes for the direct measurement of lineal energy and will characterise their response for different ion beams by experiment and modelling. Work package 2 develops techniques to measure particle track structure on different length scales in the nanometre range as well as a measurement device integrating a silicon microdosimeter and a nanodosimeter. Work package 3 investigates the indirect effects of radiation based on probes for quantifying particular radical and reactive oxygen species (ROS. Work package 4 focuses on the biological aspects of radiation damage and will produce data on initial DNA damage and late effects for radiotherapy beams of different qualities. Work package 5 provides evaluated data sets of DNA cross-sections and develops a multi-scale model to address microscopic and nanometric track structure properties. The project consortium includes three linked researchers holding so-called Researcher Excellence Grants, who carry out ancillary investigations such as developing and benchmarking a new biophysical model for induction of early radiation damage and developing methods for the translation of quantities derived from particle track structure to clinical applications in ion beam therapy.

    Korotov, S.

    2006-07-01

    In practice the process or object under analysis is usually modelled by means of a selected mathematical model, whose approximate solution is computed with a help of a certain computer code. This approximate solution necessarily includes various errors related to the approximation itself, special features of the particular method used, round-off errors, etc. Therefore, it inevitably rises the question about the reliability of the computed approximations. In the present paper we describe and test numerically the new effective computational technology designed for a control of the accuracy of approximate solutions in terms of goal-oriented quantities (or goal-oriented criteria). Such quantities are to be chosen by a user depending on solution properties that present a special interest. The technology proposed is applicable to the elliptic type boundary-value problems and leads to effective computer codes aimed to control errors of approximate solutions obtained by the finite element method which presents nowadays the main computational tool in industrial software. Various numerical tests confirming high effectivity of this technology are presented.

  17. Optimal sharing of quantity risk for a coalition of wind power producers facing nodal prices

    KAUST Repository

    Bitar, E. Y.

    2012-06-01

    It is widely accepted that aggregation of geographically diverse wind energy resources offers compelling potential to mitigate wind power variability, as wind speed at different geographic locations tends to decorrelate with increasing spatial separation. In this paper, we explore the extent to which a coalition of wind power producers can exploit the statistical benefits of aggregation to mitigate the risk of quantity shortfall with respect to forward contract offerings for energy. We propose a simple augmentation of the existing two-settlement market system with nodal pricing to permit quantity risk sharing among wind power producers by affording the group a recourse opportunity to utilize improved forecasts of their ensuing wind energy production to collectively modify their forward contracted positions so as to utilize the projected surplus in generation at certain buses to balance the projected shortfall in generation at complementary buses. Working within this framework, we show that the problem of optimally sizing a set of forward contracts for a group of wind power producers reduces to convex programming and derive closed form expressions for the set of optimal recourse policies. We also asses the willingness of individual wind power producers to form a coalition to cooperatively offer contracts for energy. We first show that the expected profit derived from coalitional contract offerings with recourse is greater than that achievable through independent contract offerings. And, using tools from coalitional game theory, we show that the core for our game is non-empty.

    Full Text Available The current study examines friendship quality and quantity as unique predictors of rejection sensitivity in adolescents. The purpose of the study was to analyze whether the unique contributions of friendship quality and quantity differ in adolescent boys and girls. Rejection sensitivity is conceptualized as the disposition to anxiously expect, readily perceive and intensively react to social rejection. That is why rejection sensitivity is considered to be a cognitive-affective mechanism which leads to increase of internalizing problems in children and adolescents (loneliness, social anxiety, depression.... Friendship variables have been found to predict the level of internalizing problems in adolescents. Little to no research, however, has examined friendship quality and quantity as predictors of level of rejection sensitivity.

Adolescents completed measures assessing number of their friends, quality of best friendship (self-report questionnaire Friendship qualities scale, Bukowski, Hoza, Boivin, 1994 and rejection sensitivity (self-report questionnaire Rejection sensitivity scale, Downey, Feldman, 1996. Regression analysis indicated that friendship features (companionship, balance, help, security, closeness, friendship quantity and overall friendship quality are significant unique predictors of sensitivity rejection in adolescents with. Results suggest that adolescents with higher number of and higher quality friendships have lower concerns about the possibility and expectation of rejection, which can lead to minimizing the risk of development of internalizing problems. However, only a small proportion of variance was accounted for in rejection sensitivity by the friendship variables (small to medium effect size. This suggests that different kind of peer relationships (peer acceptance, popularity, peer victimization make unique, differential

    Many physical phenomena that concern the research these days are basically complicated because of being multi-parametric. Thus, their study and understanding meets with big if not unsolved obstacles. Such complicated and multi-parametric is the plasmatic state as well, where the plasma and the physical quantities that appear along with it have chaotic behavior. Many of those physical quantities change exponentially and at most times they are stabilized by presenting wavy behavior. Mostly in the transitive state rather than the steady state, the exponentially changing quantities (Growth, Damping etc) depend on each other in most cases. Thus, it is difficult to distinguish the cause from the result. The present paper attempts to help this difficult study and understanding by proposing mathematical exponential models that could relate with the study and understanding of the plasmatic wavy instability behavior. Such instabilities are already detected, understood and presented in previous publications of our laboratory. In other words, our new contribution is the study of the already known plasmatic quantities by using mathematical models (modeling and simulation). These methods are both useful and applicable in the chaotic theory. In addition, our ambition is to also conduct a list of models useful for the study of chaotic problems, such as those that appear into the plasma, starting with this paper's examples.

  1. Heuristics for the Economic Production Quantity Problem under Restrictions on Production and Maintenance Time

    2016-01-01

    Full Text Available This paper proposes an economic production quantity problem with the maximal production run time and minimal preventive maintenance time over a finite planning horizon. The objective is to find the efficient production and maintenance policy to minimize the total cost composed of production, maintenance, shortages, and holding costs under the restriction on the production run time and the preventive maintenance time. The production and maintenance decisions include the production and maintenance frequencies and the production run and the maintenance time. The variability and the boundedness of the production run and maintenance time make the problem difficult to solve. Two heuristic algorithms are developed using different techniques based on the optimal properties of the relaxed problem. The performance comparison between the two algorithms is illustrated by numerical examples. The numerical results show that, for the most part, there exists a heuristic algorithm which is more effective than the other.

    Susceptibilities of conserved quantities, such as baryon number, strangeness and electric charge are sensitive to the onset of quantum chromodynamics (QCD) phase transition and are expected to provide information on the matter produced in heavy-ion collision experiments. A comprehensive study of the second-order diagonal susceptibilities and cross correlations has been made within a thermal model approach of the hadron resonance gas (HRG) model as well as with a hadronic transport model, UrQMD. We perform a detailed analysis of the effect of detector acceptances and choice of particle species in the experimental measurements of the susceptibilities for heavy-ion collisions corresponding to \\sNN = 4 GeV to 200 GeV. The transverse momentum cutoff dependence of suitably normalised susceptibilities are proposed as useful observables to probe the properties of the medium at freezeout.

    Economic sectors react strategically to climate policy, aiming at a re-distribution of rents. Established analysis suggests a Pigouvian emission tax as efficient instrument, but also recommends factor input or output taxes under specific conditions. However, existing studies leave it open whether output taxes, input taxes or input rationing perform better, and at best only touch their distributional consequences. When emissions correspond to extracted ressources, it is questionable whether taxes are effective at all. We determine the effectiveness, efficiency and functional income distribution for these instruments in the energy and resource sector, based on a game theoretic growth model with explicit factor markets and policy instruments. Market equilibrium depends on a government that acts as a Stackelberg leader with a climate protection goal. We find that resource taxes and cumulative resource quantity rationing achieve this objective efficiently. Energy taxation is only second best. Mitigation generates a substantial ''climate rent'' in the resource sector that can be converted to transfer incomes by taxes. (orig.)

    Full Text Available 5D BIM - generating cost data via the building information modelling (BIM process - has the potential to be used by quantity surveyors (QSs to streamline their workflows and increase their provision of a quality service. Consultant QSs experienced in the use of 5D BIM, from the New Zealand office of a large global practice, were interviewed on their perceptions of the benefits of, and barriers to, 5D BIM implementation within their firm. Findings suggest that 5D BIM has numerous benefits over traditional methods, chiefly through the increased efficiency and visualisation that BIM provides, along with the rapid identification of design changes. However, realisation of these perceived benefits is limited to date, due to several barriers hindering 5D BIM implementation: incomplete design and insufficient model object data in the BIM model; a lack of standards to facilitate electronic measurement; legal issues, and a lack of government support. Increasing 5D BIM implementation, in tandem with increasing use of collaborative project working through integrated project delivery, will, however, facilitate these benefits being achieved to a far greater extent in the future. Further research is recommended to identify the BIM skills which QSs will need in the future to reach the full potential of 5D BIM.

    In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented. The aim of this study was to assessed the quality and quantity of construction and demolition waste in Tehran (capital of Iran). Questionnaire methods were used for estimating the amount of generated C&D wastes national statistical data and typical waste generation data. In order to defining the composition of C&D waste, trucks were randomly selected and their wastes were separated and weighted. According to obtained results, about 82,646,051 m(3) of C&D waste (average 16,529,210 m(3) per year) were generated during 2011 to 2016 which only about 26% of them has been recycled. Mixing sand and cement, concrete, broken bricks and soil have the highest amount of the composition of C&D waste in Tehran that was 30, 19, 18 and 11%, respectively. Based on the results, about 2,784,158 t of the waste will generate in 2025 and this is approximately 122% higher than wastes generate in 2016. Based on MAPSA's data, 360 teams of personnel cruise and control the illegal disposals, but due to the expansion of Tehran this number of teams is inadequate and can't be effective in controlling the situation. In general, the overall condition of C&D waste management in Tehran seems undesirable and needs to be updated based on the experience of successful countries in this field.

    In this paper, we analyse China's current health workforce in terms of quantity, quality, and distribution. Unlike most countries, China has more doctors than nurses-in 2005, there were 1.9 million licensed doctors and 1.4 million nurses. Doctor density in urban areas was more than twice that in rural areas, with nurse density showing more than a three-fold difference. Most of China's doctors (67.2%) and nurses (97.5%) have been educated up to only junior college or secondary school level. Since 1998 there has been a massive expansion of medical education, with an excess in the production of health workers over absorption into the health workforce. Inter-county inequality in the distribution of both doctors and nurses is very high, with most of this inequality accounted for by within-province inequalities (82% or more) rather than by between-province inequalities. Urban-rural disparities in doctor and nurse density account for about a third of overall inter-county inequality. These inequalities matter greatly with respect to health outcomes across counties, provinces, and strata in China; for instance, a cross-county multiple regression analysis using data from the 2000 census shows that the density of health workers is highly significant in explaining infant mortality.

    Full Text Available Improving decisions efficiency is one of the major concerns of the decision support systems. Specially in the uncertain environment, decision support systems could be implemented efficiently to simplify decision making process. In this paper stochastic economic order quantity (EOQ problem is investigated in which decision variables and objective function are uncertain in nature and optimum probability distribution functions of them are calculated through a geometric programming model. Obtained probability distribution functions of the decision variables and the objective function are used as optimum knowledge to design a new probabilistic rule base (PRB as a decision support system for EOQ model. The developed PRB is a new type of the stochastic rule bases that can be used to infer optimum or near optimum values of the decision variables and the objective function of the EOQ model without solving the geometric programming problem directly. Comparison between the results of the developed PRB and the optimum solutions which is provided in the numerical example illustrates the efficiency of the developed PRB.

  11. Dynamic Coding of Signed Quantities in Cortical Feedback Circuits

    Dana eBallard

    2012-08-01

    Full Text Available In the early sensory and motor areas of the cortex, individual neurons transmit information about specific sensory features via a peaked response. This concept has been crystallized as `labeled lines,' to denote that axons communicate the specific properties of their sensory or motor parent cell. Such cells also can be characterized as being polarized, that is, as representing a signed quantity that is either positive or negative. We show in a model simulation that there are two important consequences when learning receptive fields using such signed codings in circuits that subtract different inputs. The first is that, in feedback circuits using labeled lines, such arithmetic operations need to be distributed across multiple distinct pathways. The second consequence is that such pathways must be necessarily dynamic, i.e. that synapses can grow and retract when forming receptive fields. The model monitors the breaking and growing of new circuit connections when their synapses need to change polarities and predicts that the rate of such changes should be inversely correlated with the progress of receptive field formation.

    We comment upon the application of Hojman's method for the determination of conservation laws in Cosmology, which has been introduced by Capozziello \\& Roshan (Phys. Lett. B 726 (2013) 471 (arXiv:1308.3910)), and has been applied recently in the cosmological scenario of a nonminimally coupled scalar field by Paolella \\& Capozziello (Phys. Lett. A (2015), in press (arXiv:1503.00098)). We apply the Ansatz, $\\phi\\left( t\\right) =\\phi\\left( a\\left( t\\right) \\right) $, which was introduced by the cited authors for a minimally-coupled scalar field, and we study the Lie and Noether point symmetries for the reduced equation. We show that under this Ansatz the unknown function of the model cannot be constrained by the requirement of the existence of a conservation law and that the Hojman conservation quantity which arises for the reduced equation is nothing more than the functional form of the Noether conservation law of momentum for the free particle. Finally we show that Hojman's method for Hamiltonian syste...

    I discuss the static quantities of the W boson, magnetic dipole and electric quadrupole moments, in the context of the minimal supersymmetric standard model, in which supersymmetry is broken by soft terms A_o,\\, m_o,\\, M_{1/2}. Following a renormalization group analysis it is found that the supersymmetric values of \\Delta k_{\\gamma} and \\Delta Q_{\\gamma} can be largely different, in some cases, from the standard model predictions but of the same order of magnitude for values of \\quad A_0,m_0,M_{1/2} \\leq {\\cal O}(1 TeV) . Therefore possible supersymmetric structure can be probed provided the accuracy of measurements for \\Delta k_{\\gamma}, \\Delta Q_{\\gamma} reaches 10^{-2}-10^{-3} and hence hard to be detected at LEP2. In cases where M_{1/2} \\ll A_0,m_0 , the charginos and neutralinos may give substantial contributions saturating the LEP2 sensitivity limits. This occurs when their masses m_{\\tilde C},m_{\\tilde Z} turn out to be both light satisfying m_{\\tilde C}+m_{\\tilde Z} \\simeq M_W . However these extreme ...

    Full Text Available This study focuses on the issues related to the waste management in river ports in general and especially in the port of Belgrade. Data on solid waste, waste oils, oily waters, gray water and black water have been collected for a period of five years. The methodology of data collection is presented. Trends of data were analyzed and the regression model was used to predict the waste quantities in the Belgrade port. This data could be utilized as a basis for the calculation of the equipment capacity for waste selective collection, treatment and storage. The results presented in this study establish the need for an orga¬nized management system for this type of waste which can be achieved either by constructing and providing new specialized terminal or by providing mobile floating facilities and other plants in the Port of Belgrade for these kinds of ser¬vices. In addition to the above, the legislative and organizational strategy of waste management has been explored to complete the study because the im¬pact of good waste management on environment and prevention of environ¬mental accidents would be highly beneficial. This study demonstrated that ad¬dressing these issues should be considered at international as well as national level.

  15. Order Quantity Distributions: Estimating an Adequate Aggregation Horizon

    Eriksen Poul Svante

    2016-09-01

    Full Text Available In this paper an investigation into the demand, faced by a company in the form of customer orders, is performed both from an explorative numerical and analytical perspective. The aim of the research is to establish the behavior of customer orders in first-come-first-serve (FCFS systems and the impact of order quantity variation on the planning environment. A discussion of assumptions regarding demand from various planning and control perspectives underlines that most planning methods are based on the assumption that demand in the form of customer orders are independently identically distributed and stem from symmetrical distributions. To investigate and illustrate the need to aggregate demand to live up to these assumptions, a simple methodological framework to investigate the validity of the assumptions and for analyzing the behavior of orders is developed. The paper also presents an analytical approach to identify the aggregation horizon needed to achieve a stable demand. Furthermore, a case study application of the presented framework is presented and concluded on.

    Objectives: It is difficult to assess sleep habits using one factor (i.e., sleep duration) alone. Regularity and quality of sleep have to be considered to assess sleep accurately. However, to our knowledge there is no scale which scores the three factors simultaneously. The purpose of this study was to inspect the reliability and validity (content, construct, and discriminant validity) of a scale we developed to screen for poor sleep habits. This scale was constructed to assess three aspects of sleep: regularity, quality, and quantity. Methods: Subjects were 563 day workers (370 men and 193 women; average age = 40.4 yr) from the manufacturing and service industries. We created a 21-item questionnaire (7 items for each of 3 factors) based on earlier studies and discussions with specialists. Reliability and construct validity of the questionnaire were assessed through item and factor analyses and Cronbach's alpha. In addition, subjects' scores were using principal component analysis, and subjects were classified according to their scores through a cluster analysis. We compared lifestyles, daytime sleepiness, stress, and chronic disease among the subjects to examine the instrument's discriminant validity. Results: Although our analysis revealed 6 items were invalid, the questionnaire assessed the three factors (regularity, quality and quantity) as expected: Cronbach's alpha was 0.744, 0.757, and 0.548, respectively. Two of the 7 quantity items were identified as assessing regularity instead, but all other items performed as expected. Four items measuring insomnia (disturbance of sleep induction, disturbance of sound sleep, nocturnal awakening, and early morning awakening) included constant burden as a quality factor. Chi-squared tests showed that the ratio of participants who took good care of their health and had less stress and daytime sleepiness was significantly high in the highest-scoring group, while the ratio of people reporting stress and chronic disease was
