  1. Transport Assessment and Risk Analysis: the case of the 2nd fixed link across the Danube River

    Salling, Kim Bang; Mudova, Nedyalka

    2009-01-01

    The scope of this paper is to present a new methodology for appraising transport infrastructure projects. Conventionally, transport infrastructure appraisal is conducted by the use of cost-benefit analyses (CBA) in order to produce aggregated single point estimates (DMT, 2003). However, new...... research has proved that the embedded uncertainties within traditional CBA such as ex-ante based investment costs and travel time savings are of high significance. The paper investigates the latter two impacts in terms of the Optimism Bias principle which is used to take account of the underestimation of...... construction costs and the overestimation of travel time savings. By extending this principle into stochastic modelling in terms of quantitative risk analysis (QRA), so-called feasibility risk assessment is provided by moving from point (deterministic CBA) to interval (stochastic QRA) results. Hereby, decision...

  9. 64 Gbit/s Transmission over 850 m Fixed Wireless Link at 240 GHz Carrier Frequency

    Kallfass, Ingmar; Boes, Florian; Messinger, Tobias; Antes, Jochen; Inam, Anns; Lewark, Ulrich; Tessmann, Axel; Henneberger, Ralf

    2015-02-01

    A directive fixed wireless link operating at a center frequency of 240 GHz achieves a data rate of 64 Gbit/s over a transmission distance of 850 m using QPSK and 8PSK modulation, in a single-channel approach without the use of spatial diversity concepts. The analog transmit and receive frontend consists of active monolithic integrated circuits including broadband RF amplification and quadrature subharmonic mixer channels. The analog frontend is addressed by 64 GSa/s ADC and DAC boards, which are amenable to real-time data transmission. A link budget calculation allows for the estimation of the performance under adverse weather conditions.

  10. The relationship between attentional blink and psychometric intelligence: A fixed-links model approach

    Rammsayer, Thomas H.; Troche, Stefan J.; KARL SCHWEIZER

    Attentional blink (AB) denotes the impairment in identifying a target when this target follows a preceding target after about 150 to 500 msec. Several models explain AB and some studies suggest that more processes than only one are involved in AB. Therefore, confounding effects of these underlying processes might be the reason why previous studies could not observe a relationship between AB and psychometric intelligence. In the present study, fixed-links models were used to disentangle the pr...

  11. High-speed, fixed-latency serial links with Xilinx FPGAs

    Xue LIU; Qing-xu DENG; Bo-ning HOU; Ze-ke WANG

    2014-01-01

    High-speed, fixed-latency serial links find application in distributed data acquisition and control systems, such as the timing trigger and control (TTC) system for high energy physics experiments. However, most high-speed serial transceivers do not keep the same chip latency after each power-up or reset, as there is no deterministic phase relationship between the transmitted and received clocks after each power-up. In this paper, we propose a fixed-latency serial link based on high-speed transceivers embedded in Xilinx field programmable gate arrays (FPGAs). First, we modify the configuration and clock distribution of the transceiver to eliminate the phase difference between the clock domains in the transmitter/receiver. Second, we use the internal alignment circuit of the transceiver and a digital clock manager (DCM)/phase-locked loop (PLL) based clock generator to eliminate the phase difference between the clock domains in the transmitter and receiver. The test results of the link latency are shown. Compared with existing solutions, our design not only implements fixed chip latency, but also reduces the average system lock time.

  14. Impact on local air quality of the Danish landworks in the fixed link across Oeresund

    The combined bridge and tunnel link between Sweden and Denmark (the Oeresund Link) and the related land constructions are expected to be in operation around the turn of the century. This new link across the Oeresund and the island Amager may result in significant changes in traffic pattern and traffic intensity - and therefore changes in air quality in some areas can not be excluded. An investigation initiated in 1994 on the Danish side of the link comprises monitoring of present air pollution at the Airport Motorway and model evaluations of future pollution levels at the motorway and in six street canyons. For all locations the pollution levels are calculated for the present situation and for scenarios for the years 2000 and 2010 both with and without the fixed link. For the future scenarios and expected development of vehicle technology is taken into account. It appears that the general air quality in the area will not be worsen. Only for benzene there is a continued risk of violation of limit values; this may however be changed by planned emission restrictions. A special situation however, may arise near the apartment buildings 'Vinkelhusene'. Here it has been decided to cover about 700 m of the motorway, in order to reduce noise and to avoid a barrier effect. This will result in increased pollution levels near the tunnel exits. All calculations are performed with dispersion models developed at the National Environmental Research Institute and are based on traffic scenarios from a traffic model developed by Anders Nyvig Ltd.

  16. The relationship between attentional blink and psychometric intelligence: A fixed-links model approach

    2009-12-01

    Full Text Available Attentional blink (AB denotes the impairment in identifying a target when this target follows a preceding target after about 150 to 500 msec. Several models explain AB and some studies suggest that more processes than only one are involved in AB. Therefore, confounding effects of these underlying processes might be the reason why previous studies could not observe a relationship between AB and psychometric intelligence. In the present study, fixed-links models were used to disentangle the processes underlying the performance of 66 female and 52 male volunteers on an AB task. In accordance with theoretical explanations of AB, three latent variables with loadings describing a linearly increasing, a linearly decreasing and a u-shaped trend described the data well. Psychometric intelligence was related to the latent variables reflected by the u-shaped (β = .30; p < .05 and the linearly increasing trends (β = .23; p < .05 but not to the latent variable reflected by the linearly decreasing trend (β = .10; n.s.. These results support the assumptions that more processes than only one are involved in AB. Decomposition of the underlying processes seems to be promising to investigate intelligence-related individual differences on this early level of information processing.

  18. Exogenous attention enhances 2nd-order contrast sensitivity.

    Barbot, Antoine; Landy, Michael S; Carrasco, Marisa

    2011-05-11

    Natural scenes contain a rich variety of contours that the visual system extracts to segregate the retinal image into perceptually coherent regions. Covert spatial attention helps extract contours by enhancing contrast sensitivity for 1st-order, luminance-defined patterns at attended locations, while reducing sensitivity at unattended locations, relative to neutral attention allocation. However, humans are also sensitive to 2nd-order patterns such as spatial variations of texture, which are predominant in natural scenes and cannot be detected by linear mechanisms. We assess whether and how exogenous attention--the involuntary and transient capture of spatial attention--affects the contrast sensitivity of channels sensitive to 2nd-order, texture-defined patterns. Using 2nd-order, texture-defined stimuli, we demonstrate that exogenous attention increases 2nd-order contrast sensitivity at the attended location, while decreasing it at unattended locations, relative to a neutral condition. By manipulating both 1st- and 2nd-order spatial frequency, we find that the effects of attention depend both on 2nd-order spatial frequency of the stimulus and the observer's 2nd-order spatial resolution at the target location. At parafoveal locations, attention enhances 2nd-order contrast sensitivity to high, but not to low 2nd-order spatial frequencies; at peripheral locations attention also enhances sensitivity to low 2nd-order spatial frequencies. Control experiments rule out the possibility that these effects might be due to an increase in contrast sensitivity at the 1st-order stage of visual processing. Thus, exogenous attention affects 2nd-order contrast sensitivity at both attended and unattended locations. PMID:21356228

  19. Nanomechanics of layer-by-layer polyelectrolyte complexes: a manifestation of ionic cross-links and fixed charges.

    Han, Biao; Chery, Daphney R; Yin, Jie; Lu, X Lucas; Lee, Daeyeon; Han, Lin

    2016-01-28

    This study investigates the roles of two distinct features of ionically cross-linked polyelectrolyte networks - ionic cross-links and fixed charges - in determining their nanomechanical properties. The layer-by-layer assembled poly(allylamine hydrochloride)/poly(acrylic acid) (PAH/PAA) network is used as the model material. The densities of ionic cross-links and fixed charges are modulated through solution pH and ionic strength (IS), and the swelling ratio, elastic and viscoelastic properties are quantified via an array of atomic force microscopy (AFM)-based nanomechanical tools. The roles of ionic cross-links are underscored by the distinctive elastic and viscoelastic nanomechanical characters observed here. First, as ionic cross-links are highly sensitive to solution conditions, the instantaneous modulus, E0, exhibits orders-of-magnitude changes upon pH- and IS-governed swelling, distinctive from the rubber elasticity prediction based on permanent covalent cross-links. Second, ionic cross-links can break and self-re-form, and this mechanism dominates force relaxation of PAH/PAA under a constant indentation depth. In most states, the degree of relaxation is >90%, independent of ionic cross-link density. The importance of fixed charges is highlighted by the unexpectedly more elastic nature of the network despite low ionic cross-link density at pH 2.0, IS 0.01 M. Here, the complex is a net charged, loosely cross-linked, where the degree of relaxation is attenuated to ≈50% due to increased elastic contribution arising from fixed charge-induced Donnan osmotic pressure. In addition, this study develops a new method for quantifying the thickness of highly swollen polymer hydrogel films. It also underscores important technical considerations when performing nanomechanical tests on highly rate-dependent polymer hydrogel networks. These results provide new insights into the nanomechanical characters of ionic polyelectrolyte complexes, and lay the ground for further

  2. Network analysis reveals ecological links between N-fixing bacteria and wood-decaying fungi.

    Björn Hoppe

    Full Text Available Nitrogen availability in dead wood is highly restricted and associations with N-fixing bacteria are thought to enable wood-decaying fungi to meet their nitrogen requirements for vegetative and generative growth. We assessed the diversity of nifH (dinitrogenase reductase genes in dead wood of the common temperate tree species Fagus sylvatica and Picea abies from differently managed forest plots in Germany using molecular tools. By incorporating these genes into a large compilation of published nifH sequences and subsequent phylogenetic analyses of deduced proteins we verified the presence of diverse pools corresponding to functional nifH, almost all of which are new to science. The distribution of nifH genes strongly correlated with tree species and decay class, but not with forest management, while higher fungal fructification was correlated with decreasing nitrogen content of the dead wood and positively correlated with nifH diversity, especially during the intermediate stage of wood decay. Network analyses based on non-random species co-occurrence patterns revealed interactions among fungi and N-fixing bacteria in the dead wood and strongly indicate the occurrence of at least commensal relationships between these taxa.

  3. A simple total loss of heat sink fix for a singer-link simulator

    The Savannah River Simulator is a middle 1980's vintage full-scope training simulator. This paper reports that exercises in the loss of heat sink regime have revealed significant short-comings in the hydraulics models for the secondary side of the plant: the software sets up flow oscillations as the zero flow condition is approached, and the algorithm is unable to produce the expected core heat up. Exceedingly simple modifications in the pressure iteration algorithm and the heat exchanger model have been found to completely cure the problems. The pathological response and the ensuing fix may be of interest to any other proprietors of simulators of similar vintage which may utilize a similar hydraulics model

  4. The ratio of 2nd to 4th digit length: a new predictor of disease predisposition?

    Manning, J T; Bundred, P E

    2000-05-01

    The ratio between the length of the 2nd and 4th digits is: (a) fixed in utero; (b) lower in men than in women; (c) negatively related to testosterone and sperm counts; and (d) positively related to oestrogen concentrations. Prenatal levels of testosterone and oestrogen have been implicated in infertility, autism, dyslexia, migraine, stammering, immune dysfunction, myocardial infarction and breast cancer. We suggest that 2D:4D ratio is predictive of these diseases and may be used in diagnosis, prognosis and in early life-style interventions which may delay the onset of disease or facilitate its early detection.

    Muir, D.; Varon, S.; Manthorpe, M. (Univ. of California, San Diego, La Jolla (USA))

    1990-03-01

    We report a quantitative method by which a single microculture can be examined for cell morphology; cell number; DNA synthesis; and expression of cell antigens. This method first involves measuring by enzyme-linked immunosorbent assay (ELISA) the total bromodeoxyuridine (BrdU) incorporation into DNA by monolayer microcultures. The BrdU-ELISA measurement was followed by simultaneous immunostaining for BrdU-positive nuclei and for a cytoplasmic antigen. The method was applied to the measurement of mitogen-induced proliferation of rat sciatic nerve Schwann cell and cerebral astroglia microcultures. The ELISA measurement of BrdU incorporation compares favorably with measurements of tritiated thymidine incorporation and offers the additional advantages that the same microculture can subsequently be examined for cell number, for cell morphology, and for the percentage of cells having BrdU-labeled nuclei and other antigens.

    The NASA Real Time Mission Monitor (RTMM) is a visualization and information system that fuses multiple Earth science data sources, to enable real time decision-making for airborne and ground validation experiments. Developed at the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center, RTMM is a situational awareness, decision-support system that integrates satellite imagery and orbit data, radar and other surface observations (e.g., lightning location network data), airborne navigation and instrument data sets, model output parameters, and other applicable Earth science data sets. The integration and delivery of this information is made possible using data acquisition systems, network communication links, network server resources, and visualizations through the Google Earth virtual globe application. In order to improve the usefulness and efficiency of the RTMM system, capabilities are being developed to allow the end-user to easily configure RTMM applications based on their mission-specific requirements and objectives. This second generation RTMM is being redesigned to take advantage of the Google plug-in capabilities to run multiple applications in a web browser rather than the original single application Google Earth approach. Currently RTMM employs a limited Service Oriented Architecture approach to enable discovery of mission specific resources. We are expanding the RTMM architecture such that it will more effectively utilize the Open Geospatial Consortium Sensor Web Enablement services and other new technology software tools and components. These modifications and extensions will result in a robust, versatile RTMM system that will greatly increase flexibility of the user to choose which science data sets and support applications to view and/or use. The improvements brought about by RTMM 2nd generation system will provide mission planners and airborne scientists with enhanced decision-making tools and capabilities to more

  20. Exogenous attention enhances 2nd-order contrast sensitivity

    Barbot, Antoine; Landy, Michael S.; Carrasco, Marisa

    2011-01-01

    Natural scenes contain a rich variety of contours that the visual system extracts to segregrate the retinal image into perceptually coherent regions. Covert spatial attention helps extract contours by enhancing contrast sensitivity for 1st-order, luminance-defined patterns at attended locations, while reducing sensitivity at unattended locations, relative to neutral attention allocation. However, humans are also sensitive to 2nd-order patterns such as spatial variations of texture, which are ...

    2000-01-21

    The 2nd U.S. Circuit Court of Appeals in New York issued two important rulings within a week on the extent to which the Americans with Disabilities Act (ADA) regulates insurance practices. [Name removed] v. Allstate Life Insurance Co. was a plaintiff-friendly decision, finding that the insurance company illegally refused to sell life insurance to a married couple because of their mental disability, major depression. [Name removed]. v. Israel Discount Bank of New York was more defendant friendly and tackled the issue of whether the ADA permits different benefit caps for mental and physical disabilities.

  8. Isotope effects on vapour phase 2nd viral coefficients

    Vapor phase 2nd virial coefficient isotope effects (VCIE's) are interpreted. A useful correlation ids developed between -Δ(B-b0)/(B-b0) = -VCIE and the reference condensed phase reduced isotopic partition function ratio [ln(fc/fg)]*. B is the second virial coefficient , b0 = 2πσ3/3, σ is the Lennard-Jones size parameter, and Δ is an isotopic difference, light-heavy. [ln(fc/fg)]* can be obtained from vapor pressure isotope effects for T/TCRITICAL p/f2g), where ln(fp/f2g) is the reduced isotopic partition function ratio describing the equilibrium between monomers and interacting pairs. At temperatures well removed from crossovers in ln(fp/f2g) or [ln(fc/fg)]*, ln(fp/f2g) = (0.4±0.2)[ln(fc/fg)]*. (author)

  19. Super Boiler 2nd Generation Technology for Watertube Boilers

    Mr. David Cygan; Dr. Joseph Rabovitser

    2012-03-31

    This report describes Phase I of a proposed two phase project to develop and demonstrate an advanced industrial watertube boiler system with the capability of reaching 94% (HHV) fuel-to-steam efficiency and emissions below 2 ppmv NOx, 2 ppmv CO, and 1 ppmv VOC on natural gas fuel. The boiler design would have the capability to produce >1500 F, >1500 psig superheated steam, burn multiple fuels, and will be 50% smaller/lighter than currently available watertube boilers of similar capacity. This project is built upon the successful Super Boiler project at GTI. In that project that employed a unique two-staged intercooled combustion system and an innovative heat recovery system to reduce NOx to below 5 ppmv and demonstrated fuel-to-steam efficiency of 94% (HHV). This project was carried out under the leadership of GTI with project partners Cleaver-Brooks, Inc., Nebraska Boiler, a Division of Cleaver-Brooks, and Media and Process Technology Inc., and project advisors Georgia Institute of Technology, Alstom Power Inc., Pacific Northwest National Laboratory and Oak Ridge National Laboratory. Phase I of efforts focused on developing 2nd generation boiler concepts and performance modeling; incorporating multi-fuel (natural gas and oil) capabilities; assessing heat recovery, heat transfer and steam superheating approaches; and developing the overall conceptual engineering boiler design. Based on our analysis, the 2nd generation Industrial Watertube Boiler when developed and commercialized, could potentially save 265 trillion Btu and $1.6 billion in fuel costs across U.S. industry through increased efficiency. Its ultra-clean combustion could eliminate 57,000 tons of NOx, 460,000 tons of CO, and 8.8 million tons of CO2 annually from the atmosphere. Reduction in boiler size will bring cost-effective package boilers into a size range previously dominated by more expensive field-erected boilers, benefiting manufacturers and end users through lower capital costs.

  1. 2nd International technical meeting on small reactors

    The 2nd International Technical Meeting on Small Reactors was held on November 7-9, 2012 in Ottawa, Ontario. The meeting was hosted by Atomic Energy of Canada Limited (AECL) and Canadian Nuclear Society (CNS). There is growing international interest and activity in the development of small nuclear reactor technology. This meeting provided participants with an opportunity to share ideas and exchange information on new developments. This Technical Meeting covered topics of interest to designers, operators, researchers and analysts involved in the design, development and deployment of small reactors for power generation and research. A special session focussed on small modular reactors (SMR) for generating electricity and process heat, particularly in small grids and remote locations. Following the success of the first Technical Meeting in November 2010, which captured numerous accomplishments of low-power critical facilities and small reactors, the second Technical Meeting was dedicated to the achievements, capabilities, and future prospects of small reactors. This meeting also celebrated the 50th Anniversary of the Nuclear Power Demonstration (NPD) reactor which was the first small reactor (20 MWe) to generate electricity in Canada.

  2. APTWG: 2nd Asia-Pacific Transport Working Group Meeting

    This conference report summarizes the contributions to and discussions at the 2nd Asia-Pacific Transport Working Group Meeting held in Chengdu, China, from 15 to 18 May 2012. The topics of the meeting were organized under five main headings: momentum transport, non-locality in transport, edge turbulence and L–H transition, three-dimensional effects on transport physics, and particle, momentum and heat pinches. It is found that lower hybrid wave and ion cyclotron wave induce co-current rotation while electron cyclotron wave induces counter-current rotation. A four-stage imaging for low (L) to high (H) confinement transition gradually emerges and a more detailed verification is urgently expected. The new edge-localized modes mitigation technique with supersonic molecular beam injection was approved to be effective to some extent on HL-2A and KSTAR. It is also found that low collisionality, trapped electron mode to ion temperature gradient transition (or transition of higher to lower density and temperature gradients), fuelling and lithium coating are in favour of inward pinch of particles in tokamak plasmas.

    Full Text Available Bergh, Z. & Theron, A.L. (Eds (2003 Psychology in a work context (2nd Ed.. Cape Town: Oxford University Press. This book is an overview and introduction to Industrial and Organisational Psychology. It is a work of ambitious scope, and it is clear that the contributors have invested a great deal of thought and effort in the planning and execution of the book. The current version is the second edition, and it looks set to become one of those standard textbooks that are revised every few years to keep up with changing times. It is a handsome volume, produced to a high standard of editorial care, pleasingly laid out and organised well enough to be useful as an occasional reference source. An English-Afrikaans glossary, tables of contents for every chapter as well as for the entire book, a comprehensive index and extensive bibliography make it easy to retrieve the information relating to a particular topic. Every chapter ends with a conclusion summarising the gist of the material covered. Quality illustrations lighten the tone and help to bring some of the concepts to life. Learning outcomes and self-assessment exercises and questions for every chapter will be useful to the lecturer using the book as a source for a tutored course, and for the student studying by distance learning. If sold at the suggested retail price, the book represents good value compared to imported textbooks that cover similar ground.

  9. Boundary value problems for the 2nd-order Seiberg-Witten equations

    Celso Melchiades Doria

    2005-02-01

    Full Text Available It is shown that the nonhomogeneous Dirichlet and Neuman problems for the 2nd-order Seiberg-Witten equation on a compact 4-manifold X admit a regular solution once the nonhomogeneous Palais-Smale condition ℋ is satisfied. The approach consists in applying the elliptic techniques to the variational setting of the Seiberg-Witten equation. The gauge invariance of the functional allows to restrict the problem to the Coulomb subspace 𝒞αℭ of configuration space. The coercivity of the 𝒮𝒲α-functional, when restricted into the Coulomb subspace, imply the existence of a weak solution. The regularity then follows from the boundedness of L∞-norms of spinor solutions and the gauge fixing lemma.

  10. 2nd interface between ecology and land development in California

    Keeley, Jon E.; Baer-Keeley, Melanie; Fortheringham, C.J.

    2000-01-01

    The 2nd Interface Between Ecology and Land Development Conference was held in association with Earth Day 1997, five years after the first Interface Conference. Rapid population growth in California has intensified the inevitable conflict between land development and preservation of natural ecosystems. Sustainable development requires wise use of diminishing natural resources and, where possible, restoration of damaged landscapes. These Earth Week Celebrations brought together resource managers, scientists, politicians, environmental consultants, and concerned citizens in an effort to improve the communication necessary to maintain our natural biodiversity, ecosystem processes and general quality of life. As discussed by our keynote speaker, Michael Soule, the best predictor of habitat loss is population growth and nowhere is this better illustrated than in California. As urban perimeters expand, the interface between wildlands and urban areas increases. Few problems are more vexing than how to manage the fire prone ecosystems indigenous to California at this urban interface. Today resource managers face increasing challenges of dealing with this problem and the lead-off section of the proceedings considers both the theoretical basis for making decisions related to prescribed burning and the practical application. Habitat fragmentation is an inevitable consequence of development patterns with significant impacts on animal and plant populations. Managers must be increasingly resourceful in dealing with problems of fragmentation and the often inevitable consequences, including susceptibility to invasive oganisms. One approach to dealing with fragmentation problems is through careful landplanning. California is the national leader in the integration of conservation and economics. On Earth Day 1991, Governor Pete Wilson presented an environmental agenda that promised to create between land owners and environmentalists, agreements that would guarantee the protection of

  11. Short rare hTERT-VNTR2-2nd alleles are associated with prostate cancer susceptibility and influence gene expression

    The hTERT (human telomerase reverse transcriptase) gene contains five variable number tandem repeats (VNTR) and previous studies have described polymorphisms for hTERT-VNTR2-2nd. We investigated how allelic variation in hTERT-VNTR2-2nd may affect susceptibility to prostate cancer. A case-control study was performed using DNA from 421 cancer-free male controls and 329 patients with prostate cancer. In addition, to determine whether the VNTR polymorphisms have a functional consequence, we examined the transcriptional levels of a reporter gene linked to these VNTRs and driven by the hTERT promoter in cell lines. Three new rare alleles were detected from this study, two of which were identified only in cancer subjects. A statistically significant association between rare hTERT-VNTR2-2nd alleles and risk of prostate cancer was observed [OR, 5.17; 95% confidence interval (CI), 1.09-24.43; P = 0.021]. Furthermore, the results indicated that these VNTRs inserted in the enhancer region could influence the expression of hTERT in prostate cancer cell lines. This is the first study to report that rare hTERT VNTRs are associated with prostate cancer predisposition and that the VNTRs can induce enhanced levels of hTERT promoter activity in prostate cancer cell lines. Thus, the hTERT-VNTR2-2nd locus may function as a modifier of prostate cancer risk by affecting gene expression

    2015-05-01

    The 2nd workshop on Germanium (Ge) detectors and technology was held at the University of South Dakota on September 14-17th 2014, with more than 113 participants from 8 countries, 22 institutions, 15 national laboratories, and 8 companies. The participants represented the following big projects: (1) GERDA and Majorana for the search of neutrinoless double-beta decay (0νββ) (2) SuperCDMS, EDELWEISS, CDEX, and CoGeNT for search of dark matter; (3) TEXONO for sub-keV neutrino physics; (4) AGATA and GRETINA for gamma tracking; (5) AARM and others for low background radiation counting; (5) as well as PNNL and LBNL for applications of Ge detectors in homeland security. All participants have expressed a strong desire on having better understanding of Ge detector performance and advancing Ge technology for large-scale applications. The purpose of this workshop was to leverage the unique aspects of the underground laboratories in the world and the germanium (Ge) crystal growing infrastructure at the University of South Dakota (USD) by brining researchers from several institutions taking part in the Experimental Program to Stimulate Competitive Research (EPSCoR) together with key leaders from international laboratories and prestigious universities, working on the forefront of the intensity to advance underground physics focusing on the searches for dark matter, neutrinoless double-beta decay (0νββ), and neutrino properties. The goal of the workshop was to develop opportunities for EPSCoR institutions to play key roles in the planned world-class research experiments. The workshop was to integrate individual talents and existing research capabilities, from multiple disciplines and multiple institutions, to develop research collaborations, which includes EPSCor institutions from South Dakota, North Dakota, Alabama, Iowa, and South Carolina to support multi-ton scale experiments for future. The topic areas covered in the workshop were: 1) science related to Ge

    2011-07-01

    Nanocrystalline Ba2NdSbO6, a complex cubic perovskite metal oxide, powders were synthesized by a self-sustained combustion method employing citric acid. The product was characterized by X-ray diffraction, differential thermal analysis, thermogravimetric analysis, Fourier transform infrared spectroscopy, transmission electron microscopy and scanning electron microscopy. The as-prepared powders were single phase Ba2NdSbO6 and a mixture of polycrystalline spheroidal particles and single crystalline nanorods. The Ba2NdSbO6 sample sintered at 1500°C for 4 h has high density (∼ 95% of theoretical density). Sintered nanocrystalline Ba2NdSbO6 had a dielectric constant of ∼ 21; and dielectric loss = 8 × 10-3 at 5 MHz.

I hope you all share my view that the whole symposium has been a very stimulating and successful experience. Also, on behalf of all the participants, I would like to take this opportunity to thank and congratulate the symposium organization committee for their excellent job in organizing and hosting our 2nd meeting. Throughout the symposium, five workshops, six keynote speeches and 66 papers, which were prepared by more than 150 academicians and practitioners from 23 different countries, reflected remarkable and various views and approaches about open and flexible learning. Besides, all these academic endeavors, 13 educational films were displayed during the symposium. The technology exhibition, hosted by seven companies, was very effective to showcase the current level of the technology and the success of applications of theory into practice. Now I would like to go over what our scholar workshop and keynote presenters shared with us: Prof. Marina McIsaac form Arizona State University dwelled on how to determine research topics worthwhile to be examined and how to choose appropriate research design and methods. She gave us clues on how to get articles published in professional journals. Prof. Colin Latchem from Australia and Prof. Dr. Ali Ekrem Ozkul from Anadolu University pointed to the importance of strategic planning for distance and flexible learning. They highlighted the advantages of strategic planning for policy-makers, planners, managers and staff. Dr. Wolfram Laaser from Fern University of Hagen, presented different multimedia clips and

  9. Pesticide toxicity index for freshwater aquatic organisms, 2nd edition

    Munn, Mark D.; Gilliom, Robert J.; Moran, Patrick W.; Nowell, Lisa H.

    2006-01-01

    The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program is designed to assess current water-quality conditions, changes in water quality over time, and the effects of natural and human factors on water quality for the Nation's streams and ground-water resources. For streams, one of the most difficult parts of the assessment is to link chemical conditions to effects on aquatic biota, particularly for pesticides, which tend to occur in streams as complex mixtures with strong seasonal patterns. A Pesticide Toxicity Index (PTI) was developed that combines pesticide exposure of aquatic biota (measured concentrations of pesticides in stream water) with acute toxicity estimates (standard endpoints from laboratory bioassays) to produce a single index value for a sample or site. The development of the PTI was limited to pesticide compounds routinely measured in NAWQA studies and to toxicity data readily available from existing databases. Qualifying toxicity data were found for one or more types of test organisms for 124 of the 185 pesticide compounds measured in NAWQA samples, but with a wide range of available bioassays per compound (1 to 232). In the databases examined, there were a total of 3,669 bioassays for the 124 compounds, including 398 48-hour EC50 values (concentration at which 50 percent of test organisms exhibit a sublethal response) for freshwater cladocerans, 699 96-hour LC50 values (concentration lethal to 50 percent of test organisms) for freshwater benthic invertebrates, and 2,572 96-hour LC50 values for freshwater fish. The PTI for a particular sample is the sum of toxicity quotients (measured concentration divided by the median toxicity concentration from bioassays) for each detected pesticide, and thus, is based on the concentration addition model of pesticide toxicity. The PTI can be calculated for specific groups of pesticides and for specific taxonomic groups. Although the PTI does not determine whether water in a sample is

    Chi, H.; Lee, H.; Shin, J.; Park, J.; Sheen, D.; Kim, G.; Che, I.; Lim, I.; Kim, T.

    2009-12-01

    Through data exchanging with China, Russia and Japan, KIGAM could monitor North Korea explosion tests in near real time with azimuthal full coverage from the test site. Except for the East Sea (Japan Sea) side, the seismic stations are distributed uniformly along the boundaries of North Korea and adjacent countries, and only stations with the distance of 200 to 550 Km from the test site were considered. Irrespective of azimuthal directions of stations from the test site, the conventional discrimination, Pn/Lg spectral ratio clearly showed that both tests were explosion. But mb-Ms discrimination did not show apparently the known pattern of explosion for both tests. Body wave magnitude, mb(Pn) of 2nd test, which was evaluated as 4.5 by KIGAM, varies with directional location of stations widely from 4.1 to 5.2. The magnitude obtained from Lg, mb(Lg), showed narrow variation between 4.3 to 4.7 with the average of 4.5. In the case of 1st test, both mb(Pn) and mb(Lg) showed equivalently large variation with directional station location. The error ellipses of epicentral determination of test site for 1st and 2nd tests showed almost identical pattern if they were separately calculated with the same configuration of stations. But the combined use of 1st and 2nd test data showed that 2nd test site was moved approximately 2 Km westward from 1st site. The cut-off frequencies of P wave of 1st and 2nd tests showed no or negligible difference even though the estimated yield of 2nd test were much larger than that of 1st one. The ratio of 1st and 2nd P-wave amplitudes showed from 2 to 3.1 times. Correspondingly the estimated energy or yield were ranged from 4 to roughly 10 times. KIGAM evaluated the yield of 2nd test were 8 times in the average larger than that of 1st one.

    Through data exchanging with China, Russia and Japan, KIGAM could monitor North Korea explosion tests in near real time with azimuthally full coverage from the test site. Except for the East Sea (Japan Sea) side, the seismic stations are distributed uniformly along the boundaries of North Korea and adjacent countries. The error ellipses of epicentral determination of test site for 1st and 2nd tests showed almost identical pattern if they were separately calculated with the same configuration of stations. But the combined use of the 1st and the 2nd test data showed that the 2nd test site was moved approximately 2 Km westward from 1st site. The Pn/Lg spectral ratio clearly discriminate these events from two nearby natural earthquakes above 4 Hz. Full moment tensor inversion also indicate the 2nd test had a very large isotropic component. But mb-Ms discrimination, which has been considered one of the most reliable discriminants for separating explosions and earthquakes, did not show apparently the known pattern of explosion for both tests. Body wave magnitude, mb(Pn) of the 2nd test, which was evaluated as 4.5 by KIGAM, varies with directional location of stations widely from 4.1 to 5.2. The magnitude obtained from Lg, mb(Lg), showed narrow variation between 4.3 to 4.7 with the average of 4.5. In the case of both 1st and 2nd tests, both mb(Pn) and mb(Lg) showed equivalently large variation with directional station location. These variations are mainly due to lateral variation of crustal structures surrounding the test site. Remarkably mb(Lg) showed very linear relationship with mb(Pn). By considering attenuation characteristics according to the propagation path, the variations could be effectively reduced. The cut-off frequencies of P wave of both tests showed no or negligible difference even though the estimated yield of the 2nd test were much larger than that of the 1st one. The ratio of P-wave amplitudes of two tests showed from 2 to 3.1 times. Correspondingly the

    We analyse the extent of intergenerational transmission through parental capital, ethnic capital and neighbourhood effects on several aspects of the school-to-work transition of 2nd generation immigrants and young ethnic Danes. The main findings are that parental capital has strong positive effects...... on the probability of completing a qualifying education and on the entry into the labour market, but it has a much smaller impact on the duration of the first employment spell and on the wage level. Growing up in neighbourhoods with a high concentration of immigrants is associated with negative...... labour market prospects both for young natives and 2nd generation immigrants....

  15. Performance and validation of COMPUCEA 2nd generation for uranium measurements in physical inventory verifications

    Full text: In order to somewhat alleviate the kind of logistical problems encountered in the in-field measurements with the current COMPUCEA equipment (COMbined Product for Uranium Content and Enrichment Assay), and with the expected benefits of saving some time and costs for the missions in mind, ITU is presently developing a 2nd generation of the COMPUCEA device. This new development also forms a task in the support programme of the Joint Research Centre of the European Commission to the IAEA. To validate the in-field performance of the newly developed 2nd generation COMPUCEA, a prototype has been tested together with the 1st generation equipment during physical inventory verification (PIV) measurements in different uranium fuel fabrication plants in Europe. In this paper we will present the prototype of COMPUCEA 2nd generation, its hardware as well as the software developed for the evaluation of the U content and 235U enrichment. We will show a comparison of the performance of the 2nd generation with the 1st generation on a larger number of uranium samples measured during the in-field PIVs. The observed excellent performance of the new COMPUCEA represents an important step in the validation of this new instrument. (author)

    We have investigated the crystal structure of deuterated lithium imide, Li{sub 2}ND, by means of neutron and X-ray diffraction. An order-disorder transition occurs near 360K. Below that temperature Li{sub 2}ND can be described to the same level of accuracy as a disordered cubic (Fd3-bar m) structure with partially occupied Li 32e sites or as a fully occupied orthorhombic (Ima2 or Imm2) structure. The high temperature phase is best characterized as disordered cubic (Fm3-bar m) with D atoms randomized over the 192l sites. Density functional theory calculations complement and support the diffraction analyses. We compare our findings in detail with previous studies.

The nuclear characteristic parameters (k∞, M2, D) were derived, and subcriticality judgment graphs were drawn for eleven kinds of fuels which were often encountered in criticality safety evaluation of fuel cycle facilities. For calculation of criticality data, benchmark calculations using the combination of the continuous energy Monte Carlo criticality code MVP and the Japanese Evaluated Nuclear Data Library JENDL-3.2 were made. The calculation errors were evaluated for this combination. The implementation of the experimental results obtained by using NUCEF facilities into the 2nd version of the Data Collection is under discussion. Therefore, related data were just mentioned. A database is being prepared to retrieve revised data easily. (author)

  10. Analysis of plume oxidation during the air pollution episode of September 2nd 1998

    Harrison, R.M.; Baggot, S.

    2001-08-01

    This study was commissioned by the Environment Agency in order to provide further investigation into the air pollution episode of September 2nd, 1998 which afflicted parts of the Midlands and South Yorkshire. A report by the Environment Agency based upon numerical modelling by the Meteorological Office indicated a number of major industrial facilities as the source of the emissions responsible for the episode. In this report an investigation is made of likely chemical changes during airmass transport and its impact on air composition at ground-level and downwind receptor locations. It is concluded that the measurements of air quality at Nottingham Centre, Stoke on Trent and Birmingham Centre on 2nd September 1998 are consistent with emissions from the sources identified in the Environment Agency report on this episode when allowance is made for oxidation of sulphur and nitrogen oxides within the plume. 3 refs., 9 figs., 9 tabs.

    2013-08-01

    Near-infrared micro-imaging will not only provide the sample's spatial distribution information, but also the spectroscopic information of each pixel. In this thesis, it took the artificial sample of wheat flour and formaldehyde sodium sulfoxylate distribution given for example to research the data processing method for enhancing the quality of near-infrared micro-imaging. Near-infrared spectroscopic feature of wheat flour and formaldehyde sodium sulfoxylate being studied on, compare correlation imaging and 2nd derivative imaging were applied in the imaging processing of the near-infrared micro-image of the artificial sample. Furthermore, the two methods were combined, i.e. 2nd derivative compare correlation imaging was acquired. The result indicated that the difference of the correlation coefficients between the two substances, i.e. wheat flour and formaldehyde sodium sulfoxylate, and the reference spectrum has been increased from 0.001 in compare correlation image to 0.796 in 2nd derivative compare correlation image respectively, which enhances the imaging quality efficiently. This study will, to some extent, be of important reference significance to near-infrared micro-imaging method research of agricultural products and foods.

    Wang Zhi-Wen; Liu Ying; Hu Mu-Hong; Li Xin-Ru; Wang Ya-Nan

    2008-01-01

    The transition energies, wavelengths and dipole oscillator strengths of 1s22p-1s2nd (3 ≤ n ≤ 9) for Cr21+ ion are calculated. The fine structure splittings of 1s2nd (n ≤ 9) states for this ion are also calculated. In calculating energy, we have estimated the higher-order relativistic contribution under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nd is determined according to the quantum defect theory. The results obtained in this paper excellently agree with the experimental data available in the literature. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from initial state 1s22p to highly excited 1s2nd states (n ≥ 10) and the oscillator strength density corresponding to the bound-free transitions are obtained.

  8. Application to non-destructive assay of 2nd layer tail cylinder at Rokkasho Enrichment plant

    International Atomic Energy Agency (IAEA) safeguards criteria 93+2 requirement stipulates that depleted uranium under the single C/S (Metal or Camera) is re-verified with 10% coverage (β=0.9) once a year, normally during physical inventory verification. In order to maintain the continuity of knowledge, the entire depleted uranium cylinders transferred from the processing area are sealed by inspectorates (the state and the IAEA) after sufficient verification with 50% coverage (β=0.5). At Rokkasho Enrichment plant, the depleted uranium cylinder (0.2∼0.3% enrichment of tail cylinder centrifuged by cascade) separated at the processing area is stored in the cylinder storage. The 2nd layer tail cylinder pile-up has been adopted for efficient-use of the storage; one block is comprised of four cylinders on the lower, three on the upper. The capacity of the specific cylinder crane is limited to as low as height of the upper cylinder. Current lifter with germanium detector is applied to the lower cylinder. However, it is highly possible that inspectorate selects random for the upper tail cylinder at the physical inventory verification. Therefore, at the verification, the operators corporate to lift down the 2nd layer tail cylinder to ground floor so that inspectorate is able to verify it. The Nuclear Material Control Center (NMCC) has designed and manufactured the specific detector lifter capable of the 2nd layer measurement and the potable detector's collimator. Afterwards, we conducted a site test in the plant and inspection efficiency and reduced operator's burden. (author)

  10. Systems Engineering Approach to Technology Integration for NASA's 2nd Generation Reusable Launch Vehicle

    Thomas, Dale; Smith, Charles; Thomas, Leann; Kittredge, Sheryl

    2002-01-01

    The overall goal of the 2nd Generation RLV Program is to substantially reduce technical and business risks associated with developing a new class of reusable launch vehicles. NASA's specific goals are to improve the safety of a 2nd-generation system by 2 orders of magnitude - equivalent to a crew risk of 1-in-10,000 missions - and decrease the cost tenfold, to approximately $1,000 per pound of payload launched. Architecture definition is being conducted in parallel with the maturating of key technologies specifically identified to improve safety and reliability, while reducing operational costs. An architecture broadly includes an Earth-to-orbit reusable launch vehicle, on-orbit transfer vehicles and upper stages, mission planning, ground and flight operations, and support infrastructure, both on the ground and in orbit. The systems engineering approach ensures that the technologies developed - such as lightweight structures, long-life rocket engines, reliable crew escape, and robust thermal protection systems - will synergistically integrate into the optimum vehicle. To best direct technology development decisions, analytical models are employed to accurately predict the benefits of each technology toward potential space transportation architectures as well as the risks associated with each technology. Rigorous systems analysis provides the foundation for assessing progress toward safety and cost goals. The systems engineering review process factors in comprehensive budget estimates, detailed project schedules, and business and performance plans, against the goals of safety, reliability, and cost, in addition to overall technical feasibility. This approach forms the basis for investment decisions in the 2nd Generation RLV Program's risk-reduction activities. Through this process, NASA will continually refine its specialized needs and identify where Defense and commercial requirements overlap those of civil missions.

  15. Editorial: 2nd Special Issue on behavior change, health, and health disparities.

    Higgins, Stephen T

    2015-11-01

    This Special Issue of Preventive Medicine (PM) is the 2nd that we have organized on behavior change, health, and health disparities. This is a topic of fundamental importance to improving population health in the U.S. and other industrialized countries that are trying to more effectively manage chronic health conditions. There is broad scientific consensus that personal behavior patterns such as cigarette smoking, other substance abuse, and physical inactivity/obesity are among the most important modifiable causes of chronic disease and its adverse impacts on population health. As such behavior change needs to be a key component of improving population health. There is also broad agreement that while these problems extend across socioeconomic strata, they are overrepresented among more economically disadvantaged populations and contribute directly to the growing problem of health disparities. Hence, behavior change represents an essential step in curtailing that unsettling problem as well. In this 2nd Special Issue, we devote considerable space to the current U.S. prescription opioid addiction epidemic, a crisis that was not addressed in the prior Special Issue. We also continue to devote attention to the two largest contributors to preventable disease and premature death, cigarette smoking and physical inactivity/obesity as well as risks of co-occurrence of these unhealthy behavior patterns. Across each of these topics we included contributions from highly accomplished policy makers and scientists to acquaint readers with recent accomplishments as well as remaining knowledge gaps and challenges to effectively managing these important chronic health problems.

  16. A novel 2nd-order bandpass MFSS filter with miniaturized structure

    C. Y. Fang

    2015-08-01

    Full Text Available In order to effectively obtain a miniaturized structure and good filtering properties, we propose a novel 2nd-order bandpass metamaterial frequency selective surface (MFSS filter which contains two capacitive layers and one inductive layer, where there are multi-loop metallic patches as shunt capacitor C and planar wire grids as series inductor L respectively. Unlike the traditional operation way—the tuned elements used in resonant surface approximately equal to one wavelength in circumference and the structure thickness with a spacing of a quarter wavelength apart, by changing the value of L and C and matching multilayer dielectric to adjust the LC coupling resonance and the resonance impedance respectively, the proposed MFSS filter can achieves a miniatured structure with ideal bandpass properties. Measurement results of the fabricated prototype of the bandpass filter (BPF indicate that the dimension of the tuned element on resonant surface is approximately 0.025 wavelength, i.e., 0.025λ. At the same time, the filter has the stable center frequency of f0 = 1.53GHz and the transmittance of T ⩾ 96.3% and high Q-value for the TE/TM wave polarization at various incidence angles. The novel 2nd-order bandpass MFSS filter with miniaturized structure not only can decrease structure dimension, but also has a wide range of applications to microwave and infrared band.

    Leber's hereditary optic neuropathy (LHON) is a mitochondrially inherited disease leading to blindness. A mitochondrial DNA point mutation at the 11778 nucleotide site of the NADH dehydrogenase subunit 4 (ND4) gene is the most common cause. The aim of this study was to evaluate the efficacy and safety of a recombinant adeno-associated virus 2 (AAV2) carrying ND4 (rAAV2-ND4) in LHON patients carrying the G11778A mutation. Nine patients were administered rAAV2-ND4 by intravitreal injection to one eye and then followed for 9 months. Ophthalmologic examinations of visual acuity, visual field, and optical coherence tomography were performed. Physical examinations included routine blood and urine. The visual acuity of the injected eyes of six patients improved by at least 0.3 log MAR after 9 months of follow-up. In these six patients, the visual field was enlarged but the retinal nerve fibre layer remained relatively stable. No other outcome measure was significantly changed. None of the nine patients had local or systemic adverse events related to the vector during the 9-month follow-up period. These findings support the feasible use of gene therapy for LHON.

  19. Scoping analysis of the Advanced Test Reactor using SN2ND

    Wolters, E.; Smith, M. (NE NEAMS PROGRAM); ( SC)

    2012-07-26

    A detailed set of calculations was carried out for the Advanced Test Reactor (ATR) using the SN2ND solver of the UNIC code which is part of the SHARP multi-physics code being developed under the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program in DOE-NE. The primary motivation of this work is to assess whether high fidelity deterministic transport codes can tackle coupled dynamics simulations of the ATR. The successful use of such codes in a coupled dynamics simulation can impact what experiments are performed and what power levels are permitted during those experiments at the ATR. The advantages of the SN2ND solver over comparable neutronics tools are its superior parallel performance and demonstrated accuracy on large scale homogeneous and heterogeneous reactor geometries. However, it should be noted that virtually no effort from this project was spent constructing a proper cross section generation methodology for the ATR usable in the SN2ND solver. While attempts were made to use cross section data derived from SCALE, the minimal number of compositional cross section sets were generated to be consistent with the reference Monte Carlo input specification. The accuracy of any deterministic transport solver is impacted by such an approach and clearly it causes substantial errors in this work. The reasoning behind this decision is justified given the overall funding dedicated to the task (two months) and the real focus of the work: can modern deterministic tools actually treat complex facilities like the ATR with heterogeneous geometry modeling. SN2ND has been demonstrated to solve problems with upwards of one trillion degrees of freedom which translates to tens of millions of finite elements, hundreds of angles, and hundreds of energy groups, resulting in a very high-fidelity model of the system unachievable by most deterministic transport codes today. A space-angle convergence study was conducted to determine the meshing and angular cubature

  1. Development of High-Speed, Low-fixed Latency Serial Links for the Router of ATLAS NSW sTGC Detector

    Hu, Xueye; The ATLAS collaboration

    2014-01-01

    The ATLAS experiment at the Large Hadron Collider (LHC) needs to be upgraded in order to cope with the increased luminosity and particle rates expected for the High Luminosity LHC (HL­LHC) running. Part of the phase­1 upgrade, to be done in the 2018/19 shutdown, is the replacement of the present muon forward detector (wheel) by a new detector, the so called New Small Wheel (NSW). The NSW detector consists of two detector technologies and the work here is on the small­strip Thin­Gap Chambers (sTGC). For sTGC, it requires very high­speed electronic triggering of signal events. The data must be quickly digitized, serialized, and transmitted off­detector for computer processing. The serialized data is sent to the trigger processor through a routing system that serves as a switchyard for all active signals. Design requirements on the router are low latency and stable/predictable data transfer timing with high­speed serial links (4.8 Gbps). We describe a 4.8 Gbps (maximum 6.6 Gbps) serial link structure base...

    2010-01-01

    In a few years, the second generation instruments of the Very Large Telescope Interferometer (VLTI) will routinely provide observations with 4 to 6 telescopes simultaneously. To reach their ultimate performance, they will need a fringe sensor capable to measure in real time the randomly varying optical paths differences. A collaboration between LAOG (PI institute), IAGL, OCA and GIPSA-Lab has proposed the Planar Optics Phase Sensor concept to ESO for the 2nd Generation Fringe Tracker. This concept is based on the integrated optics technologies, enabling the conception of extremely compact interferometric instruments naturally providing single-mode spatial filtering. It allows operations with 4 and 6 telescopes by measuring the fringes position thanks to a spectrally dispersed ABCD method. We present here the main analysis which led to the current concept as well as the expected on-sky performance and the proposed design.

  3. Tetragonal ZrO2:Nd3+ nanosphere: Combustion synthesis, luminescence and photoacoustic spectroscopy

    Gupta, Santosh K.; Chandrasekhar, D.; Kadam, R. M.

    2015-12-01

    Nanocrystalline ZrO2:Nd3+ was synthesised using gel-combustion method and characterized systematically using X-ray diffraction (XRD) and transmission electron microscopy (TEM). Through this route we can stabilize metastable tetragonal phase at 500 °C through addition of 1 mol % Nd3+ which is technologically more important. Optical characterization of the sample was done using photoluminescence (PL) and photoacoustic spectroscopy (PAS). PL studies shows an intense and optimum stimulated emission cross section of 1065 nm peak corresponding to 4F3/2 → 4I11/2 which and thus it can be a probable laser material. PAS is used to investigate electronic absorption of Nd3 in zirconia. Various covalency parameters like nephelauxetic ratio (β), covalency factor (b1/2) and Sinha parameter (δ) were evaluated for pure oxide powder and as well as for Nd3+ doped zirconia.

  17. A Perpendicular Biased 2nd Harmonic Cavity for the Fermilab Booster

    A perpendicular biased 2nd harmonic cavity is currently being designed for the Fermilab Booster. Its purpose cavity is to flatten the bucket at injection and thus change the longitudinal beam distribution so that space charge effects are decreased. It can also with transition crossing. The reason for the choice of perpendicular biasing over parallel biasing is that the Q of the cavity is much higher and thus allows the accelerating voltage to be a factor of two higher than a similar parallel biased cavity. This cavity will also provide a higher accelerating voltage per meter than the present folded transmission line cavity. However, this type of cavity presents technical challenges that need to be addressed. The two major issues are cooling of the garnet material from the effects of the RF and the cavity itself from eddy current heating because of the 15 Hz bias field ramp. This paper will address the technical challenge of preventing the garnet from overheating.

  20. Belief Functions: Theory and Applications - Proceedings of the 2nd International Conference on Belief Functions

    Masson, Marie-Hélène

    2012-01-01

    The theory of belief functions, also known as evidence theory or Dempster-Shafer theory, was first introduced by Arthur P. Dempster in the context of statistical inference, and was later developed by Glenn Shafer as a general framework for modeling epistemic uncertainty. These early contributions have been the starting points of many important developments, including the Transferable Belief Model and the Theory of Hints. The theory of belief functions is now well established as a general framework for reasoning with uncertainty, and has well understood connections to other frameworks such as probability, possibility and imprecise probability theories.   This volume contains the proceedings of the 2nd International Conference on Belief Functions that was held in Compiègne, France on 9-11 May 2012. It gathers 51 contributions describing recent developments both on theoretical issues (including approximation methods, combination rules, continuous belief functions, graphical models and independence concepts) an...

  1. Boosting biogas yield of anaerobic digesters by utilizing concentrated molasses from 2nd generation bioethanol plant

    Sarker, Shiplu [Department of Renewable Energy, Faculty of Engineering and Science, University of Agder, Grimstad-4879 (Norway); Moeller, Henrik Bjarne [Department of Biosystems Engineering, Faculty of Science and Technology, Aarhus University, Research center Foulum, Blichers Alle, Post Box 50, Tjele-8830 (Denmark)

    2013-07-01

    Concentrated molasses (C5 molasses) from 2nd generation bioethanol plant has been investigated for enhancing productivity of manure based digesters. A batch study at mesophilic condition (35+- 1 deg C) showed the maximum methane yield from molasses as 286 LCH4/kgVS which was approximately 63% of the calculated theoretical yield. In addition to the batch study, co-digestion of molasses with cattle manure in a semi-continuously stirred reactor at thermophilic temperature (50+- 1 deg C) was also performed with a stepwise increase in molasses concentration. The results from this experiment revealed the maximum average biogas yield of 1.89 L/L/day when 23% VSmolasses was co-digested with cattle manure. However, digesters fed with more than 32% VSmolasses and with short adaptation period resulted in VFA accumulation and reduced methane productivity indicating that when using molasses as biogas booster this level should not be exceeded.

  2. Nonlinear Dynamics of Memristor Based 2nd and 3rd Order Oscillators

    Talukdar, Abdul Hafiz

    2011-05-01

    Exceptional behaviours of Memristor are illustrated in Memristor based second order (Wien oscillator) and third order (phase shift oscillator) oscillator systems in this Thesis. Conventional concepts about sustained oscillation have been argued by demonstrating the possibility of sustained oscillation with oscillating resistance and dynamic poles. Mathematical models are also proposed for analysis and simulations have been presented to support the surprising characteristics of the Memristor based oscillator systems. This thesis also describes a comparative study among the Wien family oscillators with one Memristor. In case of phase shift oscillator, one Memristor and three Memristors systems are illustrated and compared to generalize the nonlinear dynamics observed for both 2nd order and 3rd order system. Detail explanations are provided with analytical models to simplify the unconventional properties of Memristor based oscillatory systems.

  5. Enabling the 2nd Generation in Space: Building Blocks for Large Scale Space Endeavours

    Barnhardt, D.; Garretson, P.; Will, P.

    Today the world operates within a "first generation" space industrial enterprise, i.e. all industry is on Earth, all value from space is from bits (data essentially), and the focus is Earth-centric, with very limited parts of our population and industry participating in space. We are limited in access, manoeuvring, on-orbit servicing, in-space power, in-space manufacturing and assembly. The transition to a "Starship culture" requires the Earth to progress to a "second generation" space industrial base, which implies the need to expand the economic sphere of activity of mankind outside of an Earth-centric zone and into CIS-lunar space and beyond, with an equal ability to tap the indigenous resources in space (energy, location, materials) that will contribute to an expanding space economy. Right now, there is no comfortable place for space applications that are not discovery science, exploration, military, or established earth bound services. For the most part, space applications leave out -- or at least leave nebulous, unconsolidated, and without a critical mass -- programs and development efforts for infrastructure, industrialization, space resources (survey and process maturation), non-traditional and persistent security situational awareness, and global utilities -- all of which, to a far greater extent than a discovery and exploration program, may help determine the elements of a 2nd generation space capability. We propose a focus to seed the pre-competitive research that will enable global industry to develop the necessary competencies that we currently lack to build large scale space structures on-orbit, that in turn would lay the foundation for long duration spacecraft travel (i.e. key technologies in access, manoeuvrability, etc.). This paper will posit a vision-to-reality for a step wise approach to the types of activities the US and global space providers could embark upon to lay the foundation for the 2nd generation of Earth in space.

  7. Geochemical evidence of paleogeography and paleoclimate during deposition of the 2nd Member of Kongdian Formation in Kongnan area

    2007-01-01

    The 2nd Member of Kongdian Formation has been made up of a large number of oil shale and mudstone in the Kongnan aera of Huanghua depression around the Bohai Bay. In the Kongnan area, the lake basins were very large and deep during the deposition of the 2nd Member of Kongdian Formation. During that period,the lakes were sealed, uncommunieated with the sea water and the paleoclimate was very warm and wet in Kongnan area. Analyzing the content of the trace element and the rare earth element, carbon and oxygen isotope in the disquisition, The authors prove the two views correct.

    2008-01-01

    Transition energies, wavelengths and dipole oscillator strengths of 1s22p - 1s2nd (3 ≤ n ≤ 9) for Fe23+ ion are calculated. The fine structure splittings of 1s2nd (n ≤ 9) states for this ion are also evaluated. The higher-order relativistic contribution to the energy is estimated under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nd is determined according to the quantum defect theory. The energies of any highly excited states with (n ≥ 10) for this series can be reliably predicted using these quantum defects as input. The results in this paper excellently agree with the experimental data available in the literature. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from same given initial state 1s22p to highly excited 1s2nd states (n ≥ 10) and the oscillator strength density corresponding to the bound-free transitions is obtained.

  17. Severe weather phenomena: SQUALL LINES The case of July 2nd 2009

    Paraschivescu, Mihnea; Tanase, Adrian

    2010-05-01

    The wind intensity plays an important role, among the dangerous meteorological phenomena, to produce negative effects on the economy and the social activities, particularly when the wind is about to turn into a storm. During the past years one can notice an increase of wind frequency and intensity due to climate changes and, consequently, as a result of the extreme meteorological phenomena not only on a planetary level but also on a regional one. Although dangerous meteorological phenomena cannot be avoided, since they are natural, nevertheless they can be anticipated and decision making institutions and mass media can be informed. This is the reason why, in this paper, we set out to identify the synoptic conditions that led to the occurrence of the severe storm case in Bucharest on July 2nd, 2009, as well as the matrices that generate such cases. At the same time we sought to identify some indications evidence especially from radar data so as to lead to the improvement of the time interval between the nowcasting warning and the actual occurrence of the phenomenon.

  18. Geodesign from Theory to Practice: From Metaplanning to 2nd Generation of Planning Support Systems

    Michele Campagna

    2014-05-01

    Full Text Available This paper deals with the concept of Geodesign, a new approach to spatial planning and design which is grounded on extensive use of Geographic Information Science methods and tools. As a method Geodesign is intended to inform projects since their conceptualization, to analysis and diagnosis, to design of alternatives and impact simulation, and eventually the final choice. This approach appears particularly urgent and actual to many scholars from academia and practitioners from the industry and the planning practice for advances in GIScience nowadays offer unprecedented data and tools to manage territorial knowledge for decision-making support. The author argues research in Geodesign may contribute to solve major actual pitfalls in sustainable spatial planning: namely it may offer methods to help planners to inform sustainable design alternatives with environmental considerations and contextually assess their impacts; secondly, it may help to ensure more transparent, responsible, and accountable democratic decision-making processes. The argumentation is supported by the author recent research results with regards to the evolution from 1st generation Planning Support Systems (PSS, to metaplanning and 2nd generation PSS.

  19. Production of artificial ionospheric layers by frequency sweeping near the 2nd gyroharmonic

    T. Pedersen

    2011-01-01

    Full Text Available Artificial ionospheric plasmas descending from the background F-region have been observed on multiple occasions at the High Frequency Active Auroral Research Program (HAARP facility since it reached full 3.6 MW power. Proximity of the transmitter frequency to the 2nd harmonic of the electron gyrofrequency (2fce has been noted as a requirement for their occurrence, and their disappearance after only a few minutes has been attributed to the increasing frequency mismatch at lower altitudes. We report new experiments employing frequency sweeps to match 2fce in the artificial plasmas as they descend. In addition to revealing the dependence on the 2fce resonance, this technique reliably produces descending plasmas in multiple transmitter beam positions and appears to increase their stability and lifetime. High-speed ionosonde measurements are used to monitor the altitude and density of the artificial plasmas during both the formation and decay stages.

    Full Text Available On April 2nd, the Macedonian Scientific Society for Autism, for the fourth time organized an event on the occasion of the International Day of Persons with Autism. The event with cultural and artistic character was held at the Museum of the Macedonian Struggle under the motto “They are not alone, we are with them”. The huge number of citizens only confirmed the motto. It seemed that the hall of the Museum of the Macedonian Struggle is too small for the warm hearts of the audience. More than 300 guests were present in the hall, among which there were children with autism and their families, prominent professors, doctors, special educators and rehabilitators, psychologists, students and other citizens with glad heart and will who decided to enrich the event with their presence. The event was opened by the violinist Plamenka Trajkovska, which performed one song. After her, the President of the Macedonian Scientific Society for Autism, PhD. Vladimir Trajkovski delivered his speech. The professor told the parents of autistic children, who were present in large number, not to lose hope, to fight for their children, and that the Macedonian Scientific Society for Autism will provide tremendous support and assistance in this struggle.

  1. Deaf-mute teaching during the Spanish 2nd Republic period. A historical view

    Alfredo ALCINA MADUEÑO

    2011-07-01

    Full Text Available Deaf-mute teaching during the Spanish 2nd Republic period is an issue which has never been studied in depth consideration and some of its aspects have been not even touched by any research. We could say that deaf-mute education is granted with the characteristics found in general education, at least regarding this specific stage, mainly: economic and budget thoughtful following effort by the governments, methodological renovation, modernization of the educative system, spreading of the school-net, teachers’ formation, etcetera. However it is true that we can fin a very strict-stated idiosyncrasy, which sometimes turns out to be even controversial, not only due to the opposition of different political parties in power during different 2-years periods (31/37 and 34/35, but also because of the republican-socialist governments decisions regarding educative policy. The Republican legacy consists actually much more in documentary facts than in actual realisations, and will have much more application within that political regime that follows and annihilates the Republic than within the period of the Republic itself. The consideration of primary sources (both legal and documental is the base that supports the final conclusions that are provided by means of this exposition.

  2. Proceedings of the 2nd CSNI Specialist Meeting on Simulators and Plant Analysers

    The safe utilisation of nuclear power plants requires the availability of different computerised tools for analysing the plant behaviour and training the plant personnel. These can be grouped into three categories: accident analysis codes, plant analysers and training simulators. The safety analysis of nuclear power plants has traditionally been limited to the worst accident cases expected for the specific plant design. Many accident analysis codes have been developed for different plant types. The scope of the analyses has continuously expanded. The plant analysers are now emerging tools intended for extensive analysis of the plant behaviour using a best estimate model for the whole plant including the reactor and full thermodynamic process, both combined with automation and electrical systems. The comprehensive model is also supported by good visualisation tools. Training simulators with real time plant model are tools for training the plant operators to run the plant. Modern training simulators have also features supporting visualisation of the important phenomena occurring in the plant during transients. The 2nd CSNI Specialist Meeting on Simulators and Plant Analysers in Espoo attracted some 90 participants from 17 countries. A total of 49 invited papers were presented in the meeting in addition to 7 simulator system demonstrations. Ample time was reserved for the presentations and informal discussions during the four meeting days. (orig.)

    Full Text Available 14-17 May 2013, Oslo, NorwayWe have received more than 200 full papers for the 2nd International Conference for Design Education Researchers in Oslo.This international conference is a springboard for sharing ideas and concepts about contemporary design education research. Contributors are invited to submit research that deals with different facets of contemporary approaches to design education research. All papers will be double-blind peer-reviewed. This conference is open to research in any aspect and discipline of design educationConference themeDesign Learning for Tomorrow - Design Education from Kindergarten to PhDDesigned artefacts and solutions influence our lives and values, both from a personal and societal perspective. Designers, decision makers, investors and consumers hold different positions in the design process, but they all make choices that will influence our future visual and material culture. To promote sustainability and meet global challenges for the future, professional designers are dependent on critical consumers and a design literate general public.  For this purpose design education is important for all. We propose that design education in general education represents both a foundation for professional design education and a vital requirement for developing the general public’s competence for informed decision making.REGISTRATION AT http://www.hioa.no/DRScumulus

  6. Improved beam spot measurements in the 2nd generation proton beam writing system

    Nanosized ion beams (especially proton and helium) play a pivotal role in the field of ion beam lithography and ion beam analysis. Proton beam writing has shown lithographic details down to the 20 nm level, limited by the proton beam spot size. Introducing a smaller spot size will allow smaller lithographic features. Smaller probe sizes, will also drastically improve the spatial resolution for ion beam analysis techniques. Among many other requirements, having an ideal resolution standard, used for beam focusing and a reliable focusing method, is an important pre-requisite for sub-10 nm beam spot focusing. In this paper we present the fabrication processes of a free-standing resolution standard with reduced side-wall projection and high side-wall verticality. The resulting grid is orthogonal (90.0° ± 0.1), has smooth edges with better than 6 nm side-wall projection. The new resolution standard has been used in focusing a 2 MeV H2+ beam in the 2nd generation PBW system at Center for Ion Beam Applications, NUS. The beam size has been characterized using on- and off-axis scanning transmission ion microscopy (STIM) and ion induced secondary electron detection, carried out with a newly installed micro channel plate electron detector. The latter has been shown to be a realistic alternative to STIM measurements, as the drawback of PIN diode detector damage is alleviated. With these improvements we show reproducible beam focusing down to 14 nm

  7. Study of Application for Excursion Observation Method in Primary School 2nd Grade Social Studies

    Ahmet Ali GAZEL

    2014-04-01

    Full Text Available This study aims to investigate how field trips are conducted at 2nd grade of primary schools as a part of social studies course. Data for this research is compiled from 143 permanent Social Studies teachers working throughout 2011–2012 Education Year in the primary schools of central Kütahya and its districts. Data is compiled by using descriptive search model. In the research, after taking expert opinions, a measuring tool developed by the researcher is used. Data obtained from the research were transferred to computer, and analyses were made. In the analysis of the data, frequency and percentage values have been used to determine the distribution. Also a single factor variance analysis and t-test for independent samples have been used to determine the significance of difference between the variables. As a result of the research, it has been realized that insufficient importance is given to field trip method in Social Studies lessons. Most of the teachers using this method apply it in spring months. Teachers usually make use of field trips independent from unit/topic to increase the students’ motivation, and they generally use verbal expression in the class after tours. The biggest difficulty teachers encounter while using tour-observation method is the students’ undisciplined behavior.

  8. The 2nd and 3rd lower molars development of in utero gamma irradiated mouse fetus and neonates

    Pregnant mothers were irradiated by a single dose of gamma rays (0, 2, 4, 6 Gy cobalt 60) in the days 10, 12, 14, 16, 18 of pregnancy. The heads of the embryos, and those of the neonates were taken at consecutive intervals of irradiation, starting from 16 days of pregnancy till 3rd day after delivery. The effect of irradiation was investigated in the development of the 2nd and 3rd lower molars on serial tissue sections, within consecutive periods of their organogenesis. Irradiation led to growth-deficiency in the 2nd and 3rd molars, and causes delay in their development. This was observed in various degree depending on the dose, time of irradiation, and time after irradiation. This belated development was manifested in morphogenesis, histogenesis, and odontoblasts and ameloblastis cyto and functional differentiations. The study showed that the delay in the development-stages of the 2nd lower molar, under control, if compared with the same process, to which is exposed, the 1st lower molar - within two days difference - dose not diminish the later irradiation effect on the 2nd molar, when compared with the immediate irradiation effect in the 1st molar (demonstrated in a previous study by Osman and Al-Achkar, 2001). On the contrary, the present study showed that the 2nd lower molar is more radiosensitive to various doses than the 1st lower molar. Also it showed the irradiation with two doses 4 and 6 Gy leads to a delay in the formation of the 3rd lower molar's bud, and it does not go deeper beyond the lower molar. (Author)

  9. SrAl2O4∶Eu2+, Nd3+ and Dy3+ Long Afterglow Phosphor

    何大伟; 吕菁华; 崔兴龙

    2003-01-01

    The SrAl2O4∶Eu2+, Nd3+ and SrAl2O4∶Eu2+, Dy3+ long afterglow phosphor were synthesized. Their excitation and emission spectra at different excitation and afterglow characteristics were analyzed after the excitation power was taken off. The effects of Eu2+, Dy3+, Nd3+ mole concentrations on phosphorescence characteristics were also discussed. It is crucial to have trapping levels located at a suitable depth related to the thermal release rate at room temperature. The incorporation of Nd3+ ions as an auxiliary activator into the SrAl2O4∶Eu2+ system causes very intense and long phosphorescence. The response time of SrAl2O4∶Eu2+, Dy3+ phosphors is quicker than that of SrAl2O4∶Eu2+, Nd3+. Phosphorescence characteristics of SrAl2O4∶Eu2+, Nd3+ is much better than those of SrAl2O4∶Eu2+, Dy3+. The integrate area of the excitation spectrum of SrAl2O4∶Eu2+, Nd3+ phosphor is larger than that of SrAl2O4∶Eu2+, Dy3+ phosphor within the range of 250~360 nm. For phosphorescence characteristics to the system of SrAl2O4∶Eu2+, Nd3+ phosphor, the optimum concentration of Nd3+ trivalent rare earth ions is 0.05 mol.

  11. Mechanosensitivity of the 2nd Kind: TGF-β Mechanism of Cell Sensing the Substrate Stiffness

    Cockerill, Max; Rigozzi, Michelle K.; Terentjev, Eugene M.

    2015-01-01

    Cells can sense forces applied to them, but also the stiffness of their environment. These are two different phenomena, and here we investigate the mechanosensitivity of the 2nd kind: how the cell can measure an elastic modulus at a single point of adhesion—and how the cell can receive and interpret the chemical signal released from the sensor. Our model uses the example of large latent complex of TGF-β as a sensor. Stochastic theory gives the rate of breaking of latent complex, which initiates the signaling feedback loop after the active TGF-β release and leads to a change of cell phenotype driven by the α-smooth muscle actin. We investigate the dynamic and steady-state behaviors of the model, comparing them with experiments. In particular, we analyse the timescale of approach to the steady state, the stability of the non-linear dynamical system, and how the steady-state concentrations of the key markers vary depending on the elasticity of the substrate. We discover a crossover region for values of substrate elasticity closely corresponding to that of the fibroblast to myofibroblast transition. We suggest that the cell could actively vary the parameters of its dynamic feedback loop to ‘choose’ the position of the transition region and the range of substrate elasticity that it can detect. In this way, the theory offers the unifying mechanism for a variety of phenomena, such as the myofibroblast conversion in fibrosis of wounds and lungs and smooth muscle cell dysfunction in cardiac disease.

  13. Re-fighting the 2nd Anglo-Boer War: historians in the trenches

    Ian Van der Waag

    Full Text Available Some one hundred years ago, South Africa was tom apart by the 2nd Anglo- Boer War (1899-1902. The war was a colossal psychological experience fought at great expense: It cost Britain twenty-two thousand men and £223 million. The social, economic and political cost to South Africa was greater than the statistics immediately indicate: at least ten thousand fighting men in addition to the camp deaths, where a combination of indifference and incompetence resulted in the deaths of 27 927 Boers and at least 14 154 Black South Africans. Yet these numbers belie the consequences. It was easy for the British to 'forget' the pain of the war, which seemed so insignificant after the losses sustained in 1914-18. With a long history of far-off battles and foreign wars, the British casualties of the Anglo-Boer War became increasingly insignificant as opposed to the lesser numbers held in the collective Afrikaner mind. This impact may be stated somewhat more candidly in terms of the war participation ratio for the belligerent populations. After all, not all South Africans fought in uniform. For the Australian colonies these varied between 4½per thousand (New South Wales to 42.3 per thousand (Tasmania. New Zealand 8 per thousand, Britain 8½ per thousand: and Canada 12.3 per thousand; while in parts of South Africa this was perhaps as high as 900 per thousand. The deaths and high South African participation ratio, together with the unjustness of the war in the eyes of most Afrikaners, introduced bitterness, if not a hatred, which has cast long shadows upon twentieth-century South Africa.

  14. The Ratio of 2nd to 4th Digit Length in Korean Alcohol-dependent Patients

    2016-01-01

    Objective The ratio of 2nd to 4th digit length (2D:4D) is a sexually dimorphic trait. Men have a relatively shorter second digit than fourth digit. This ratio is thought to be influenced by higher prenatal testosterone level or greater sensitivity to androgen. The purpose of this study is to investigate the relationship between alcohol dependence and 2D:4D in a Korean sample and whether 2D:4D can be a biologic marker in alcohol dependence. Methods In this study, we recruited 87 male patients with alcohol dependence from the alcohol center of one psychiatric hospital and 52 healthy male volunteers who were all employees in the same hospital as controls. We captured images of the right and left hands of patients and controls using a scanner and extracted data with a graphics program. We measured the 2D:4D of each hand and compared the alcohol dependence group with the control group. We analyzed these ratios using an independent-samples t-test. Results The mean 2D:4D of patients was 0.934 (right hand) and 0.942 (left hand), while the mean 2D:4D of controls was 0.956 (right hand) and 0.958 (left hand). Values for both hands were significantly lower for patients than controls (p<0.001, right hand; p=0.004, left hand). Conclusion Patients who are alcohol dependent have a significantly lower 2D:4D than controls, similar to the results of previous studies, which suggest that a higher prenatal testosterone level in the gonadal period is related to alcoholism. Furthermore, 2D:4D is a possible predictive marker of alcohol dependence. PMID:27121425

  15. Thermoluminescent and stuctural properties of BaAl2O4:Eu2+,Nd3+,Gd3+phosphors prepared by combustion method

    BaAl2O4:Eu2+,Nd3+,Gd3+ phosphors were prepared by a combustion method at different initiating temperatures (400–1200 °C), using urea as a comburent. The powders were annealed at different temperatures in the range of 400–1100 °C for 3 h. X-ray diffraction data show that the crystallinity of the BaAl2O4 structure greatly improved with increasing annealing temperature. Blue-green photoluminescence, with persistent/long afterglow, was observed at 498 nm. This emission was attributed to the 4f65d1–4f7 transitions of Eu2+ ions. The phosphorescence decay curves were obtained by irradiating the samples with a 365 nm UV light. The glow curves of the as-prepared and the annealed samples were investigated in this study. The thermoluminescent (TL) glow peaks of the samples prepared at 600 °C and 1200 °C were both stable at ∼72 °C suggesting that the traps responsible for the bands were fixed at this position irrespective of annealing temperature. These bands are at a similar position, which suggests that the traps responsible for these bands are similar. The rate of decay of the sample annealed at 600 °C was faster than that of the sample prepared at 1200 °C.

  5. Emotional and Behavioral Disorders in 1.5th Generation, 2nd Generation Immigrant Children, and Foreign Adoptees.

    Tan, Tony Xing

    2016-10-01

    Existing theories (e.g., acculturative stress theory) cannot adequately explain why mental disorders in immigrants are less prevalent than in non-immigrants. In this paper, the culture-gene co-evolutionary theory of mental disorders was utilized to generate a novel hypothesis that connection to heritage culture reduces the risk for mental disorders in immigrant children. Four groups of children aged 2-17 years were identified from the 2007 United States National Survey of Children's Health: 1.5th generation immigrant children (n = 1378), 2nd generation immigrant children (n = 4194), foreign adoptees (n = 270), and non-immigrant children (n = 54,877). The 1.5th generation immigrant children's connection to their heritage culture is stronger than or similar to the 2nd generation immigrants, while the foreign adoptees have little connection to their birth culture. Controlling for age, sex, family type and SES, the odds for having ADD/ADHD, Conduct Disorder, Anxiety Disorder, and Depression diagnosis were the lowest for the 1.5th generation immigrant children, followed by the 2nd generation immigrant children and the foreign adoptees. The foreign adoptees and non-adopted children were similar in the odds of having these disorders. Connection to heritage culture might be the underlying mechanism that explained recent immigrants' lower rates of mental disorders. PMID:26972324

    This white paper recommends that ASTM International develop standards to address the potential impact of hydrides on the long term performance of irradiated zirconium alloys. The need for such standards was apparent during the 2nd ASTM International Workshop on Hydrides in Zirconium Alloy Cladding and Assembly Components, sponsored by ASTM International Committee C26.13 and held on June 10-12, 2014, in Jackson, Wyoming. The potentially adverse impacts of hydrogen and hydrides on the long term performance of irradiated zirconium-alloy cladding on used fuel were shown to depend on multiple factors such as alloy chemistry and processing, irradiation and post irradiation history, residual and applied stresses and stress states, and the service environment. These factors determine the hydrogen content and hydride morphology in the alloy, which, in turn, influence the response of the alloy to the thermo-mechanical conditions imposed (and anticipated) during storage, transport and disposal of used nuclear fuel. Workshop presentations and discussions showed that although hydrogen/hydride induced degradation of zirconium alloys may be of concern, the potential for occurrence and the extent of anticipated degradation vary throughout the nuclear industry because of the variations in hydrogen content, hydride morphology, alloy chemistry and irradiation conditions. The tools and techniques used to characterize hydrides and hydride morphologies and their impacts on material performance also vary. Such variations make site-to-site comparisons of test results and observations difficult. There is no consensus that a single material or system characteristic (e.g., reactor type, burnup, hydrogen content, end-of life stress, alloy type, drying temperature, etc.) is an effective predictor of material response during long term storage or of performance after long term storage. Multi-variable correlations made for one alloy may not represent the behavior of another alloy exposed to

    Dear Sirs,

    The Public Health Genomics European Network (PHGEN is a mapping exercise for the responsible and effective integration of genome-based knowledge and technologies into public policy and health services for the benefit of population health. In 2005, the European Commission called for a “networking exercise…to lead to an inventory report on genetic determinants relevant for public health”[1], this lead to the funding of a PHGEN three year project (EC project 2005313.This project started in early 2006 with a kick-off meeting in Bielefeld / Germany.The project work is comprised of, according to the public health trias, three one year periods of assessment, policy development and assurance.At the end of the assessment phase a network meeting was held in Rome from January, 31st to February 2nd 2007 with over 90 network members and network observers in attendance. The participants represented different organisations throughout the European Union with expertise in areas such as human genetics and other medical disciplines,epidemiology,public health, law, ethics, political and social sciences. The aim of the meeting was to wrap up the last year’s assessment period and to herald the policy development phase.The assessment period of PHGEN was characterised by several activities: - Contact and cooperation with other European and internationally funded networks and projects on public health genomics or related issues (e.g. EuroGenetest, EUnetHTA, Orphanet, IPTS, PHOEBE, GRaPHInt, P3G - Identification of key experts in public health genomics in the European members states, applicant countries and EFTA/EEA countries from different disciplines (e.g. human genetics and other medical disciplines, public health, law, philosophy, epidemiology, political and social sciences - Building up national task forces on public health genomics in the above mentioned countries - Establishing and work in three working groups: public health genomics

    Students in science, particularly in physics, face a fascinating and challenging future. Scientists have proposed very interesting theories, which describe the microscopic and macroscopic world fairly well, trying to match the quantum regime with cosmological scales. Between the extremes of this scenario, biological phenomena in all their complexity take place, challenging the laws we observe in the atomic and sub-atomic world. More and more accurate and complex experiments have been devised and these are now going to test the paradigms of physics. Notable experiments include: the Large Hadronic Collider (LHC), which is going to shed light on the physics of the Standard Model of Particles and its extensions; the Planck-Herschel satellites, which target a very precise measurement of the properties of our Universe; and the Free Electron Lasers facilities, which produce high-brilliance, ultrafast X-ray pulses, allowing the investigation of the fundamental processes of solid state physics, chemistry, and biology. These projects are the result of huge collaborations spread across the world, involving scientists belonging to different and complementary research fields: physicists, chemists, biologists and others, keen to make the best of these extraordinary laboratories. Even though each branch of science is experiencing a process of growing specialization, it is very important to keep an eye on the global picture, remaining aware of the deep interconnections between inherent fields. This is even more crucial for students who are beginning their research careers. These considerations motivated PhD students and young post-docs connected to the Roman scientific research area to organize a conference, to establish the background and the network for interactions and collaborations. This resulted in the 1st and 2nd Young Researchers Meetings in Rome (http://ryrm.roma2.infn.it), one day conferences aimed primarily at graduate students and post-docs, working in physics in Italy

  9. Archaeometric study of glass beads from the 2nd century BC cemetery of Numantia

    García Heras, Manuel

    2003-06-01

    Full Text Available Recent archaeologícalf ieldwork undertaken in the Celtiberian cremation necropolis of Numantia (Soria, Spain has provided a group of glass beads from the 2nd century BC. Such glass beads were part, together with other metallic and ceramic items, of the offerings deposited with the dead. They are ring-shaped in typology and deep-blue, amber, or semitransparent white in colour. This paper reports results derived from the chemical and microstructural characterization carried out on a representative sample set of this group of beads. The main goal of the research was to find out about their production technology to explore their probable provenance. In addítion, corrosion mechanisms were also assessed to determine the influence of crematíon on the beads' structure. The resulting data suggest that these blue and amber beads were made using soda-lime silicate glass, whereas semi-transparent white ones were manufactured from alumino-silicate glass. It has also determined that some transition metal oxides were used as chromophores, as well as lead oxide for decoration.

    La reciente excavación de la necrópolis celtibérica de Numancia (Garray, Soria ha permitido recuperar un conjunto de cuentas de vidrio del siglo II a.C.

  10. The theory of contractions of 2D 2nd order quantum superintegrable systems and its relation to the Askey scheme for hypergeometric orthogonal polynomials

    We describe a contraction theory for 2nd order superintegrable systems, showing that all such systems in 2 dimensions are limiting cases of a single system: the generic 3-parameter potential on the 2-sphere, S9 in our listing. Analogously, all of the quadratic symmetry algebras of these systems can be obtained by a sequence of contractions starting from S9. By contracting function space realizations of irreducible representations of the S9 algebra (which give the structure equations for Racah/Wilson polynomials) to the other superintegrable systems one obtains the full Askey scheme of orthogonal hypergeometric polynomials.This relates the scheme directly to explicitly solvable quantum mechanical systems. Amazingly, all of these contractions of superintegrable systems with potential are uniquely induced by Wigner Lie algebra contractions of so(3, C) and e(2, C). The present paper concentrates on describing this intimate link between Lie algebra and superintegrable system contractions, with the detailed calculations presented elsewhere. Joint work with E. Kalnins, S. Post, E. Subag and R. Heinonen.

    It was an honor and a great pleasure for all those involved in its organization to welcome the participants to the ''Radio and Antenna Days of the Indian Ocean'' (RADIO 2014) international conference that was held from 7th to 10th April 2014 at the Sugar Beach Resort, Wolmar, Flic-en-Flac, Mauritius. RADIO 2014 is the second of a series of conferences organized in the Indian Ocean region. The aim of the conference is to discuss recent developments, theories and practical applications covering the whole scope of radio-frequency engineering, including radio waves, antennas, propagation, and electromagnetic compatibility. The RADIO international conference emerged following discussions with engineers and scientists from the countries of the Indian Ocean as well as from other parts of the world and a need was felt for the organization of such an event in this region. Following numerous requests, the Island of Mauritius, worldwide known for its white sandy beaches and pleasant tropical atmosphere, was again chosen for the organization of the 2nd RADIO international conference. The conference was organized by the Radio Society, Mauritius and the Local Organizing Committee consisted of scientists from SUPELEC, France, the University of Mauritius, and the University of Technology, Mauritius. We would like to take the opportunity to thank all people, institutions and companies that made the event such a success. We are grateful to our gold sponsors CST and FEKO as well as URSI for their generous support which enabled us to partially support one PhD student and two scientists to attend the conference. We would also like to thank IEEE-APS and URSI for providing technical co-sponsorship. More than hundred and thirty abstracts were submitted to the conference. They were peer-reviewed by an international scientific committee and, based on the reviews, either accepted, eventually after revision, or rejected.

    2009-03-31

    This is the year-end report of the 2nd year of the NUMO-LBNL collaborative project: Development of Hydrologic Characterization Technology of Fault Zones under NUMO-DOE/LBNL collaboration agreement, the task description of which can be found in the Appendix 3. Literature survey of published information on the relationship between geologic and hydrologic characteristics of faults was conducted. The survey concluded that it may be possible to classify faults by indicators based on various geometric and geologic attributes that may indirectly relate to the hydrologic property of faults. Analysis of existing information on the Wildcat Fault and its surrounding geology was performed. The Wildcat Fault is thought to be a strike-slip fault with a thrust component that runs along the eastern boundary of the Lawrence Berkeley National Laboratory. It is believed to be part of the Hayward Fault system but is considered inactive. Three trenches were excavated at carefully selected locations mainly based on the information from the past investigative work inside the LBNL property. At least one fault was encountered in all three trenches. Detailed trench mapping was conducted by CRIEPI (Central Research Institute for Electric Power Industries) and LBNL scientists. Some intriguing and puzzling discoveries were made that may contradict with the published work in the past. Predictions are made regarding the hydrologic property of the Wildcat Fault based on the analysis of fault structure. Preliminary conceptual models of the Wildcat Fault were proposed. The Wildcat Fault appears to have multiple splays and some low angled faults may be part of the flower structure. In parallel, surface geophysical investigations were conducted using electrical resistivity survey and seismic reflection profiling along three lines on the north and south of the LBNL site. Because of the steep terrain, it was difficult to find optimum locations for survey lines as it is desirable for them to be as

The 2nd-order DROS gradiometer has a noise level of 20 fT/Hz at 1 Hz and 8 fT/Hz at 200 Hz inside the heavily-shielded MSR with a shielding factor of10{sup 3}at 1 Hz and 10{sup 4} - 10{sup 5} at 100 Hz. The poorly-shielded MSR, built of a 12-mm-thick aluminum layer and 4-6 permalloy layers of 0.35 mm thickness, is 2.4 m x 2.4 m x 2.4 m in size, and has a shielding factor of 40 at 1 Hz, 10{sup 4} at 100 Hz. Our 64-channel second-order gradiometer MCG system consists of 64 2nd-order DROS gradiometers, flux-locked loop electronics, and analog signal processors. With the 2nd-order DROS gradiometers and flux-locked loop electronics installed inside the poorly-shielded MSR, and with the analog signal processor installed outside it, the noise level was measured to be 20 fT/Hz at 1 Hz and 8 fT/Hz at 200 Hz on the average even though the MSR door is open. This result leads to a low noise level, low enough to obtain a human MCG at the same level as that measured in the heavily-shielded MSR. However, filters or active shielding is needed fur clear MCG when there is large low-frequency noise from heavy air conditioning or large ac power consumption near the poorly-shielded MSR.

  16. Virtual Visit to the ATLAS Control Room by 2nd High School of Eleftherio–Kordelio in Thessaloniki

    2013-01-01

    Our school is the 2nd High School of Eleftherio – Kordelio. It is located at the west suburbs of Thessaloniki in Greece and our students are between 15-17 years old. Thessaloniki is the second largest city in Greece with a port of a major role in trading at the area of South Balkans. During this period of time our students have heard so much about CERN and the great discoveries which have taken place there and they are really keen on visiting and learning many things about it.

  17. Order and disorder in Ca2ND0.90H0.10-A structural and thermal study

    The structure of calcium nitride hydride and its deuterided form has been re-examined at room temperature and studied at high temperature using neutron powder diffraction and thermal analysis. When synthesised at 600 deg. C, a mixture of both ordered and disordered Ca2ND0.90H0.10 phases results. The disordered phase is the minor component and has a primitive rocksalt structure (spacegroup Fm3m) with no ordering of D/N on the anion sites and the ordered phase is best described using the rhombohedral spacegroup R-3m with D and N arranged in alternate layers in (111) planes. This mixture of ordered and disordered phases exists up to 580 deg. C, at which the loss of deuterium yields Ca2ND0.85 with the disappearance of the disordered phase. In the new ordered phase there exists a similar content of vacancies on both anion sites; to achieve this balance, a little N transfers onto the D site, whereas there is no indication of D transferring onto the N-sites. These observations are thought to indicate that the D/N ordering is difficult to achieve with fully occupied anion sites. It has previously been reported that Ca2ND has an ordered cubic cell with alternating D and N sites in the [100] directions ; however, for the samples studied herein, there were clearly two coexisting phases with apparent broadening/splitting of the primitive peaks but not for the ordered peaks. The rhombohedral phase was in fact metrically cubic; however, all the observed peaks were consistent with the rhombohedral unit cell with no peaks requiring the larger ordered cubic unit cell to be utilised. Furthermore this rhombohedral cell displays the same form of N-D ordering as the Sr and Ba analogues, which are metrically rhombohedral. - Graphical abstract: Ca2ND0.90H0.10 forms a mixture of ordered and disordered phases when synthesised at 600 deg. C. The ordered phase disappears at high temperature upon release of structural deuterium/hydrogen, leaving a single, partially disordered phase. Research

  18. FOREWORD: 2nd International Workshop on New Computational Methods for Inverse Problems (NCMIP 2012)

    Blanc-Féraud, Laure; Joubert, Pierre-Yves

    2012-09-01

    Conference logo This volume of Journal of Physics: Conference Series is dedicated to the scientific contributions presented during the 2nd International Workshop on New Computational Methods for Inverse Problems, (NCMIP 2012). This workshop took place at Ecole Normale Supérieure de Cachan, in Cachan, France, on 15 May 2012, at the initiative of Institut Farman. The first edition of NCMIP also took place in Cachan, France, within the scope of the ValueTools Conference, in May 2011 (http://www.ncmip.org/2011/). The NCMIP Workshop focused on recent advances in the resolution of inverse problems. Indeed inverse problems appear in numerous scientific areas such as geophysics, biological and medical imaging, material and structure characterization, electrical, mechanical and civil engineering, and finance. The resolution of inverse problems consists of estimating the parameters of the observed system or structure from data collected by an instrumental sensing or imaging device. Its success firstly requires the collection of relevant observation data. It also requires accurate models describing the physical interactions between the instrumental device and the observed system, as well as the intrinsic properties of the solution itself. Finally, it requires the design of robust, accurate and efficient inversion algorithms. Advanced sensor arrays and imaging devices provide high rate and high volume data; in this context, the efficient resolution of the inverse problem requires the joint development of new models and inversion methods, taking computational and implementation aspects into account. During this one-day workshop, researchers had the opportunity to bring to light and share new techniques and results in the field of inverse problems. The topics of the workshop were: algorithms and computational aspects of inversion, Bayesian estimation, kernel methods, learning methods, convex optimization, free discontinuity problems, metamodels, proper orthogonal decomposition

  19. Sustainable development - a role for nuclear power? 2nd scientific forum

    The 2nd Scientific Forum of the International Atomic Energy Agency (IAEA) was held during the 43rd General Conference. This paper summarizes the deliberations of the two-day Forum. The definition of 'sustainable development' of the 1987 Bruntland Commission - 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs' - provided the background for the Forum's debate whether and how nuclear power could contribute to sustainable energy development. The framework for this debate comprises different perspectives on economic, energy, environmental, and political considerations. Nuclear power, along with all energy generating systems, should be judged on these considerations using a common set of criteria (e.g., emission levels, economics, public safety, wastes, and risks). First and foremost, there is a growing political concern over the possible adverse impact of increasing emissions of greenhouse gases from fossil fuel combustion. However, there is debate as to whether this would have any material impact on the predominantly economic criteria currently used to make investment decisions on energy production. According to the views expressed, the level of safety of existing nuclear power plants is no longer a major concern - a view not yet fully shared by the general public. The need to maintain the highest standards of safety in operation remains, especially under the mounting pressure of competitiveness in deregulated and liberalized energy markets. The industry must continuously reinforce a strong safety culture among reactor designers, builders, and operators. Furthermore, a convincing case for safety will have to be made for any new reactor designs. Of greater concern to the public and politicians are the issues of radioactive waste and proliferation of nuclear weapons. There is a consensus among technical experts that radioactive wastes from nuclear power can be disposed of safely and

    Since the Brain Order Disorder (BOD) group reported on a high density Electroencephalogram (EEG) to capture the neuronal information using EEG to wirelessly interface with a Smartphone [1,2], a larger BOD group has been assembled, including the Obama BRAIN program, CUA Brain Computer Interface Lab and the UCSD Swartz Computational Neuroscience Center. We can implement the pair-electrodes correlation functions in order to operate in a real time daily environment, which is of the computation complexity of O(N3) for N=102~3 known as functional f-EEG. The daily monitoring requires two areas of focus. Area #(1) to quantify the neuronal information flow under arbitrary daily stimuli-response sources. Approach to #1: (i) We have asserted that the sources contained in the EEG signals may be discovered by an unsupervised learning neural network called blind sources separation (BSS) of independent entropy components, based on the irreversible Boltzmann cellular thermodynamics(ΔS brain at constant temperature, we can solve the minimum of Helmholtz free energy (H = E - TS) by computing BSS, and then their pairwise-entropy source correlation function. (i) Although the entropy itself is not the information per se, but the concurrence of the entropy sources is the information flow as a functional-EEG, sketched in this 2nd BOD report. Area #(2) applying EEG bio-feedback will improve collective decision making (TBD). Approach to #2: We introduce a novel performance quality metrics, in terms of the throughput rate of faster (Δt) & more accurate (ΔA) decision making, which applies to individual, as well as team brain dynamics. Following Nobel Laureate Daniel Kahnmen's novel "Thinking fast and slow", through the brainwave biofeedback we can first identify an individual's "anchored cognitive bias sources". This is done in order to remove the biases by means of individually tailored pre-processing. Then the training effectiveness can be maximized by the collective product Δt *

  1. Proceedings of the 2nd JAERI symposium on HTGR technologies October 21 ∼ 23, 1992, Oarai, Japan

    The Japan Atomic Energy Research Institute (JAERI) held the 2nd JAERI Symposium on HTGR Technologies on October 21 to 23, 1992, at Oarai Park Hotel at Oarai-machi, Ibaraki-ken, Japan, with support of International Atomic Energy Agency (IAEA), Science and Technology Agency of Japan and the Atomic Energy Society of Japan on the occasion that the construction of the High Temperature Engineering Test Reactor (HTTR), which is the first high temperature gas-cooled reactor (HTGR) in Japan, is now being proceeded smoothly. In this symposium, the worldwide present status of research and development (R and D) of the HTGRs and the future perspectives of the HTGR development were discussed with 47 papers including 3 invited lectures, focusing on the present status of HTGR projects and perspectives of HTGR Development, Safety, Operation Experience, Fuel and Heat Utilization. A panel discussion was also organized on how the HTGRs can contribute to the preservation of global environment. About 280 participants attended the symposium from Japan, Bangladesh, Germany, France, Indonesia, People's Republic of China, Poland, Russia, Switzerland, United Kingdom, United States of America, Venezuela and the IAEA. This paper was edited as the proceedings of the 2nd JAERI Symposium on HTGR Technologies, collecting the 47 papers presented in the oral and poster sessions along with 11 panel exhibitions on the results of research and development associated to the HTTR.

  2. Surface-emitting quantum cascade laser with 2nd-order metal-semiconductor gratings for single-lobe emission

    Boyle, C.; Sigler, C.; Kirch, J. D.; Lindberg, D.; Earles, T.; Botez, D.; Mawst, L. J.

    2016-03-01

    Grating-coupled, surface-emitting (GCSE) quantum-cascade lasers (QCLs) are demonstrated with high-power, single-lobe surface emission. A 2nd-order Au-semiconductor distributed-feedback (DFB)/ distributed-Bragg-reflector (DBR) grating is used for feedback and out-coupling. The DFB and DBR grating regions are 2.55 mm- and 1.28 mm-long, respectively, for a total grating length of 5.1 mm. The lasers are designed to operate in a symmetric longitudinal mode by causing resonant coupling of the guided optical mode to the antisymmetric surface-plasmon modes of the 2nd-order metal/semiconductor grating. In turn, the antisymmetric longitudinal modes are strongly absorbed by the metal in the grating, causing the symmetric longitudinal mode to be favored to lase, which produces a single lobe beam over a grating duty-cycle range of 36-41 %. Simulations indicate that the symmetric mode is always favored to lase, independent of the random phase of residual reflections from the device's cleaved ends. Peak pulsed output powers of ~ 0.4 W were measured with single-lobe, single-mode operation near 4.75 μm.

  3. Synthetic CO, H2 and HI surveys of the Galactic 2nd Quadrant, and the properties of molecular gas

    Duarte-Cabral, A; Dobbs, C L; Mottram, J C; Gibson, S J; Brunt, C M; Douglas, K A

    2014-01-01

    We present CO, H2, HI and HISA distributions from a set of simulations of grand design spirals including stellar feedback, self-gravity, heating and cooling. We replicate the emission of the 2nd Galactic Quadrant by placing the observer inside the modelled galaxies and post process the simulations using a radiative transfer code, so as to create synthetic observations. We compare the synthetic datacubes to observations of the 2nd Quadrant of the Milky Way to test the ability of the current models to reproduce the basic chemistry of the Galactic ISM, as well as to test how sensitive such galaxy models are to different recipes of chemistry and/or feedback. We find that models which include feedback and self-gravity can reproduce the production of CO with respect to H2 as observed in our Galaxy, as well as the distribution of the material perpendicular to the Galactic plane. While changes in the chemistry/feedback recipes do not have a huge impact on the statistical properties of the chemistry in the simulated g...

  4. Numerical stability of 2nd order Runge-Kutta integration algorithms for use in particle-in-cell codes

    An essential ingredient of particle-in-cell (PIC) codes is a numerically accurate and stable integration scheme for the particle equations of motion. Such a scheme is the well known time-centered leapfrog (LF) method accurate to 2nd order with respect to the timestep Δt. However, this scheme can only be used for forces independent of velocity unless a simple enough implicit implementation is possible. The LF scheme is therefore inapplicable in Monte-Carlo treatments of particle collisions and/or interactions with radio-frequency fields. We examine here the suitability of the 2nd order Runge-Kutta (RK) method. We find that the basic RK scheme is numerically unstable, but that conditional stability can be attained by an implementation which preserves phase space area. Examples are presented to illustrate the performance of the RK schemes. We compare analytic and computed electron orbits in a traveling nonlinear wave and also show self-consistent PIC simulations describing plasma flow in the vicinity of a lower hybrid antenna.

  5. Time resolved 2nd harmonic generation at LaAlO3/SrTiO3 Interfaces

    Adhikari, Sanjay; Eom, Chang-Beom; Ryu, Sangwoo; Cen, Cheng

    2014-03-01

    Ultrafast spectroscopy can produce information of carrier/lattice dynamics, which is especially valuable for understanding phase transitions at LaAlO3/SrTiO3 interfaces. LaAlO3 (LAO) and SrTiO3 (STO) are both associated with wide band gap, which allows deep penetration of commonly used laser wavelengths and therefore usually leads to overwhelming bulk signal background. Here we report a time resolved study of a 2nd harmonic generation (SHG) signal resulting from impulsive below-the-band-gap optical pumping. The nonlinear nature of the signal enables us to probe the interface directly. Output of a home built Ti:Sapphire laser and BBO crystal were used to generate 30fs pulses of two colors (405nm and 810nm). The 405nm pulse was used to pump the LAO/STO interfaces, while 2nd harmonics of the 810nm pulse generated at the interfaces was probed as a function of the time delay. Signals from samples with varying LAO thicknesses clearly correlates to the metal-insulator transition. Distinct time dependent signals were observed at LAO/STO interfaces grown on different substrates. Experiments performed at different optical polarization geometries, interface electric fields and temperatures allow us to paint a clearer picture of the novel oxide heterostructures under investigation.

  6. BMI differences in 1st and 2nd generation immigrants of Asian and European origin to Australia.

    Hauck, Katharina; Hollingsworth, Bruce; Morgan, Lawrie

    2011-01-01

    We estimate assimilation of immigrants' body mass index (BMI) to the host population of Australia over one generation, conducting separate analyses for immigrants from 7 regions of Europe and Asia. We use quantile regressions to allow for differing impact of generational status across 19 quantiles of BMI from under-weight to morbidly obese individuals. We find that 1st generation South European immigrants have higher, and South and East Asian immigrants have lower BMI than Australians, but have assimilated to the BMI of their hosts in the 2nd generation. There are no or only small BMI differences between Australians and 1st and 2nd generation immigrants from East Europe, North-West Europe, Middle East and Pacific regions. We conclude that both upward and downward assimilation in some immigrant groups is most likely caused by factors which can change over one generation (such as acculturation), and not factors which would take longer to change (such as genetics). Our results suggest that public health policies targeting the lifestyles of well educated Asian immigrants may be effective in preventing BMI increase in this subgroup. PMID:20869292

    a while to find the bits you want. The index lists neither lambda nor the cosmological constant, and inflation is said to appear on pp 307-412. The chapters are of equal length, in traditional textbook fashion. Neither volume has much to say about issues that are currently 'hot'-the importance of extra dimensions, fine tuning of cosmological parameters, possible evidence for cosmic geometry different from the simplest. Discussions of such things will, of course, date a textbook quickly. On the other hand, they are often the items that physics (etc) students will have heard about in colloquia and would like to have clarified. Names appear only as eponyms, from Altarelli Parisi evolution (which is not on the page to which B and G's index refers you) to the Zeeman effect, which is where PS's index says it is. Can I imagine using either of these as texts? Definitely yes for PS, since it is a possible fit to an astrophysics course that UCI offers as a 'vocabulary builder' for students coming out of mainstream physics (and for which we have yet to find an entirely suitable text). We are contemplating a faculty hire or two in astro-particle physics, in which case B and G might well be a good fit to a seminar for students beginning work in that area. If I were asked to teach the course, however, I would probably want an instructor's solution manual for the text problems. One may well exist, though the book does not mention it. Using PS, you will have to make up your own problems (which you can then reasonably be expected to be able to work without help).

    2012-01-01

    This volume contains most of the links to the presentations delivered at this international workshop. This meeting was the second in the series following the previous I Encuentro Ib\\'erico de Compstar, held at the University of Coimbra, Portugal in 2010. The main purpose of this meeting was to strengthen the scientific collaboration between the participants of the Iberian and the rest of the southern European branches of the European Nuclear Astrophysics network, formerly, COMPSTAR. This ESF (European Science Foundation) supported network has been crucial in helping to make a broader audience for the the most interesting and relevant research lines being developed currently in Nuclear Astrophysics, especially related to the physics of neutron stars. The program of the meeting was tailored to theoretical descriptions of the physics of neutron stars although some input from experimental observers and other condensed matter and optics areas of interest was also included.

  9. Early prediction for necessity of 2nd I-131 ablation therapy with serum thyroglobulin levels in patients with differentiated thyroid cancer

    The aim of our study was to evaluate the predictive value of serum thyroglobulin levels, measured at preoperative status and just before 1st I-131 ablation therapy with high serum TSH, for necessity of 2nd I-131 ablation therapy in differentiated thyroid cancer patients. 111 patients with DTC who underwent total or near total thyroidectomy followed by immediate I-131 ablation therapy, were enrolled in this study. TSH, Tg and anti-Tg autoantibody were measured before thyroidectomy (TSHpreop, Tgpreop and Anti-Tgpreop) and just before 1st I-131 ablation therapy (TSHabl, Tgabl and Anti-Tgabl). All TSHabl levels were above 30mU/liter, ATg [(Tgpreop-Tgabl)X100/(Tgpreop)] was calculated. 29 patients(26.1%, 29/111) had to receive 2nd I-131 ablation therapy. Of 70 patients whose Tgabl were under 10 ng/ml, only 11 patients had received 2nd I-131 ablation therapy (15.7%). Patients with Tgabl greater than or equal to 10 ng/ml had received 2nd I-131 ablation therapy (18/41, 43.9%) than patients with lower Tgabl level. There was a disparity of necessity of 2nd I-131 ablation therapy between two groups(Tgabl <10 ng/ml and Tgabl =10 ng/ml, two by two /2 test p=0.0016). Of 41 patients with Tgabl greater than or equal to 10 ng/ml, 19 patients showed increased Tg levels (ATg<0). Patients with negative ATg and Tgabl greater than or equal to 10 ng/ml showed a strikingly high necessity of 2nd I-131 ablation therapy (11/19, 57.9%). There was also a significant disparity of necessity of 2nd I-131 ablation therapy between two groups(ATg<0 + Tgabl =10 ng/ml and the others, two by two /2 test, p=0.0012). These results suggest that high Tgabl level just before 1st I-131 ablation therapy can forecast the necessity of 2nd I-131 ablation therapy. Moreover, Difference of Tg level between preoperative status and just before 1st I-131 ablation therapy could also suggest necessity of 2nd I-131 ablation therapy at early period of DTC patients surveillance

  13. Results of the independent verification of radiological remedial action at 217 South 2nd East Street, Monticello, Utah (MS00097)

    In 1980 the site of a vanadium and uranium mill at Monticello, Utah, was accepted into the US Department of Energy's (DOE's) Surplus Facilities Management Program, with the objectives of restoring the government-owned mill site to safe levels of radioactivity, disposing of or containing the tailings in an environmentally safe manner, and performing remedial actions on off-site (vicinity) properties that had been contaminated by radioactive material resulting from mill operations. During 1985 and 1986, UNC Geotech, the remedial action contractor designated by DOE, performed remedial action on the vicinity property at 217 South 2nd East Street, Monticello, Utah. The Pollutant Assessments Group (PAG) of Oak Ridge National Laboratory was assigned the responsibility of verifying the data supporting the adequacy of remedial action and confirming the site's compliance with DOE guidelines. The PAG found that the site successfully meets the DOE remedial action objectives. Procedures used by PAG are described. 3 refs., 2 tabs

  14. Anatomy of a 2nd-order unconformity: stratigraphy and facies of the Bakken formation during basin realignment

    Skinner, Orion; Canter, Lyn; Sonnenfeld, Mark; Williams, Mark [Whiting Oil and Gas Corp., Denver, CO (United States)

    2011-07-01

    Because classic Laramide compressional structures are relatively rare, the Williston Basin is often considered as structurally simple, but because of the presence of numerous sub-basins, simplistic lithofacies generalization is impossible, and detailed facies mapping is necessary to unravel Middle Bakken paleogeography. The unconformity above the Devonian Three Forks is explained by the infilling and destruction of the Devonian Elk Point basin, prepares the Bakken system, and introduces a Mississippian Williston Basin with a very different configuration. Black shales are too often considered as deposits that can only be found in deep water, but to a very different conclusion must be drawn after a review of stratigraphic geometry and facies successions. The whole Bakken is a 2nd-order lowstand to transgressive systems tract lying below the basal Lodgepole, which represents an interval of maximal flooding. This lowstand to transgressive stratigraphic context explains why the sedimentary process and provenance shows high aerial variability.

  15. 2nd International Symposium "Atomic Cluster Collisions : Structure and Dynamics from the Nuclear to the Biological Scale"

    Solov'yov, Andrey; ISACC 2007; Latest advances in atomic cluster collisions

    2008-01-01

    This book presents a 'snapshot' of the most recent and significant advances in the field of cluster physics. It is a comprehensive review based on contributions by the participants of the 2nd International Symposium on Atomic Cluster Collisions (ISACC 2007) held in July 19-23, 2007 at GSI, Darmstadt, Germany. The purpose of the Symposium is to promote the growth and exchange of scientific information on the structure and properties of nuclear, atomic, molecular, biological and complex cluster systems studied by means of photonic, electronic, heavy particle and atomic collisions. Particular attention is devoted to dynamic phenomena, many-body effects taking place in cluster systems of a different nature - these include problems of fusion and fission, fragmentation, collective electron excitations, phase transitions, etc.Both the experimental and theoretical aspects of cluster physics, uniquely placed between nuclear physics on the one hand and atomic, molecular and solid state physics on the other, are discuss...

  16. Dancing links

    Knuth, Donald E

    2009-01-01

    The author presents two tricks to accelerate depth-first search algorithms for a class of combinatorial puzzle problems, such as tiling a tray by a fixed set of polyominoes. The first trick is to implement each assumption of the search with reversible local operations on doubly linked lists. By this trick, every step of the search affects the data incrementally. The second trick is to add a ghost square that represents the identity of each polyomino. Thus puts the rule that each polyomino be used once on the same footing as the rule that each square be covered once. The coding simplifies to a more abstract form which is equivalent to 0-1 integer programming. More significantly for the total computation time, the search can naturally switch between placing a fixed polyomino or covering a fixed square at different stages, according to a combined heuristic. Finally the author reports excellent performance for his algorithm for some familiar puzzles. These include tiling a hexagon by 19 hexiamonds and the N queen...

  20. Clinical evaluation of the 2nd generation radio-receptor assay for anti-thyrotropin receptor antibodies (TRAb) in Graves' disease

    Full text: Detection of autoantibodies to the TSH receptor by radioreceptorial assays (RRA) is largely requested in clinical practice for the diagnosis of Graves' disease and its differentiation from diffuse thyroid autonomy. Additionally, TRAb measurement during antithyroid drug treatment can be useful to evaluate the risk of disease's relapse alter therapy discontinuation. Nevertheless, some patients affected by Graves' disease are TRAb negative when 1st generation assay is used. Recently a new RRA method for TRAb assay was developed by using human recombinant TSH-receptor and solid-phase technique. Aim of our work was the comparison between 1st and 2nd generation TRAb assays in Graves' disease patients and, particularly, the evaluation of 2nd generation test in a sub-group of patients affected by Graves' disease but with negative 1st generation TRAb assay. We evaluated the diagnostic performance of a newly developed 2nd generation TRAb assay (DYNOtest(r) TRAK human, BRAHMS Diagnostica GmbH, Germany) in 46 patients affected by Graves' disease with negative 1st generation TRAb assay (TRAK Assay(r), BRAHMS Diagnostica GmbH, Germany) . A control groups of 50 Graves' disease patients with positive 1st generation TRAb assay, 50 patients affected by Hashimoto's thyroiditis and 50 patients affected by nodular goiter were also examined. 41 out of 46 patients affected by Graves' disease with negative 1st generation TRAb assay showed a positive 2nd generation test. The overall sensitivity of the 2nd generation test was significantly improved respect the 1st generation assay in Graves' disease patients (χ2 = 22.5, p<0.0001). 1 and 3 out of 50 patients affected by Hashimoto's thyroiditis were positive by 1st and 2nd generation TRAB assay, respectively. All these patients showed primary hypothyroidism. No differences resulted in euthyroid Hashimoto's thyroiditis sub-group and in nodular goiter control group. The 2nd generation TRAB assay is clearly more sensitive than the 1

  1. Relative fixed point theory

    Ponto, Kate

    2009-01-01

    The Lefschetz fixed point theorem and its converse have many generalizations. One of these generalizations is to endomorphisms of a space relative to a fixed subspace. In this paper we define relative Lefschetz numbers and Reidemeister traces using traces in bicategories with shadows. We use the functoriality of this trace to identify different forms of these invariants and to prove a relative Lefschetz fixed point theorem and its converse.

  2. Proving Fixed Points

    Grall, Hervé

    2010-01-01

    We propose a method to characterize the fixed points described in Tarski's theorem for complete lattices. The method is deductive: the least and greatest fixed points are "proved" in some inference system defined from deduction rules. We also apply the method to two other fixed point theorems, a generalization of Tarski's theorem to chain-complete posets and Bourbaki-Witt's theorem. Finally, we compare the method with the traditional iterative method resorting to ordinals and the original imp...

  3. Roles of doping ions in afterglow properties of blue CaAl2O4:Eu2+,Nd3+ phosphors

    Eu2+ doped and Nd3+ co-doped calcium aluminate (CaAl2O4:Eu2+,Nd3+) phosphor was prepared by a urea-nitrate solution combustion method at furnace temperatures as low as 500 °C. The produced CaAl2O4:Eu2+,Nd3+ powder was investigated in terms of phase composition, morphology and luminescence by X-Ray diffraction (XRD), Scanning Electron Microscope (SEM), Fourier Transform Infra Red spectroscopy (FTIR) and Photoluminescence (PL) techniques respectively. XRD analysis depicts a dominant monoclinic phase that indicates no change in the crystalline structure of the phosphor with varying concentration of Eu2+ and Nd3+. SEM results show agglomerates with non-uniform shapes and sizes with a number of irregular network structures having lots of voids and pores. The Energy Dispersive X-ray Spectroscopy (EDS) and (FTIR) spectra confirm the expected chemical components of the phosphor. PL measurements indicated one broadband excitation spectra from 200 to 300 nm centered around 240 nm corresponding to the crystal field splitting of the Eu2+ d-orbital and an emission spectrum in the blue region with a maximum on 440 nm. This is a strong indication that there was dominantly one luminescence center, Eu2+ which represents emission from transitions between the 4f7 ground state and the 4f6–5d1 excited state configuration. High concentrations of Eu2+ and Nd3+ generally reduce both intensity and lifetime of the phosphor powders. The optimized content of Eu2+ is 1 mol% and for Nd3+ is 1 mol% for the obtained phosphors with excellent optical properties. The phosphor also emits visible light at around 587 and 616 nm. Such emissions can be ascribed to the 5D0–7F1 and 5D0–7F2 intrinsic transition of Eu3+ respectively. The decay characteristics exhibit a significant rise in initial intensity with increasing Eu2+ doping concentration while the decay time increased with Nd3+ co-doping. The observed afterglow can be ascribed to the generation of suitable traps due to the presence of the Nd

  6. Design of control system for the 2nd and 3rd charge exchange system in J-PARC 3GeV RCS

    J-PARC 3GeV Synchrotron Accelerator is using method of charge exchange injection using three carbon foils. In order to achieve this injection, three charge exchange devices installed in this facility. These devices are controlled by one control system. The 2nd and 3rd charge exchange devices are upgrading to increase maintainability and exhaust ability of the vacuum unit, and the control system has reconsidered. Basic policy of redesigning the control system is separated from centralized control system of the three devices, and we reconstruct the control system that independent from the centralized control system. On this condition, we are upgrading of the 2nd and 3rd charge exchange device. It is necessary to redesign the interlock unit about safety, because of being stand-alone control. Now, the error signal of the charge exchange unit consolidates the error signal of three devices, and it operates the Machine Protection System (MPS). Therefore, we needed long time to search occasion why the error happened. However, the MPS will be operated by the error signal on each unit, we hope it makes a difference to search occasion easily. The 2nd and 3rd charge exchange units adopt a simple control system using Yokogawa electric PLC FA-M3. We are designing of the control system with safety that fuses the drive unit and the vacuum unit. This report is about design of the 2nd and 3rd charge exchange unit control system that reconstructed the hardware of their unit. (author)

  8. Dielectric properties of [Ca1-x(Li1/2Nd1/2)x]1-yZnyTiO3 ceramics at microwave frequencies

    Dielectric properties of Ca1-x(Li1/2Nd1/2)xTiO3 (0.0≤x≤0.6, CLNT) and [Ca0.6(Li1/2Nd1/2)0.4]1-yZnyTiO3 (0.5≤y≤1.0, CLNZT) ceramics were investigated at 4-10 GHz. For the CLNT system, a single perovskite phase was detected in the entire composition range. The dielectric constants (K), and the temperature coefficients of the resonant frequency (TCF) were dependent on the B-site bond valence. Qf value decreases with the increase in (Li1/2Nd1/2)TiO3 content (x) due to a decrease in grain size. For the CLNZT system, Qf value and TCF were improved with Zn content (y) due to the formation of Zn2TiO4. Typically, K of 47, Qf of 13000 GHz, TCF of 14 ppm per deg. C were obtained for [Ca0.6(Li1/2Nd1/2)0.4]0.4Zn0.6TiO3 sintered at 1150 deg. C for 4 h

    A self-activated crystal Na2Nd2O(BO3)2 has been grown from the Na2O-Nd2O3-B2O3-NaF system. Its structure was determined by single crystal X-ray diffraction, and verified by infrared spectrum and inductively coupled plasma optical emission spectrometry. Na2Nd2O(BO3)2 crystallizes in the monoclinic crystal system, space group P21/c with unit-cell parameters a = 10.804 Å, b = 6.421 Å, c = 10.450 Å, β = 117.95°, Z = 4, and V = 640.4 Å3. Its absorption and emission spectra were measured at room temperature. Based on the absorption spectrum, the spontaneous transition probabilities, fluorescence branch ratio, and the radiation lifetime of 4F3/2 state were calculated. The emission properties under the 355 nm excitation were also evaluated. The electronic structure of Na2Nd2O(BO3)2 was calculated by the first-principles method. The obtained results show that Na2Nd2O(BO3)2 may be a promising microchip laser material.

  11. Evolution of Corruption in Sub-Saharan Africa - from Nkruma To Mutharika The 2nd: Case Study Of South Africa

    Mavhungu Abel Mafukata

    2015-03-01

    Full Text Available Since Sub-Saharan Africa's first independence in Ghana, the region has experienced massive and costly political and bureaucratic corruption within public service and administration. The causes of the corruption, its nature and form are wide and intertwined. In Sub-Saharan Africa, efforts to curb corruption have failed to discard it. The paper focused on the period from Nkruma in Ghana to Mutharika the 2nd in Malawi. This paper reviewed existing literature on political and bureaucratic corruption in Sub-Saharan Africa while on the other hand the paper employed key informant interviews to gather the required data to investigate, analyse and profile the genesis and evolution of corruption in Sub-Saharan Africa. The key informant interviews were employed to solicit public views and opinion from nineteen key informant participants (n=19 selected from 11 countries in Sub-Saharan Africa. The paper found that corruption is legendary; has entrenched itself to becoming some sort of culture in the region, and has become the most difficult socio-economic challenge to resolve in the region despite the various anti-corruption efforts employed by stakeholders to curb it. It emerged through the study that law-enforcement efforts against corruption need some reinforcement in order to be effective and eficient in uprooting corruption in the region. If Sub-Saharan Africa fails to address its corruption challenge, its development prospects would seriously curtailed.

  12. Near infrared emission and energy transfer in Eu2+ - Nd3+ co-doped Ca2BO3Cl

    Talewar, R. A.; Joshi, C. P.; Moharil, S. V.

    2016-05-01

    Novel near infrared (NIR) emitting phosphor, Ca2BO3Cl:Eu2+, Nd3+ was synthesized by conventional solid-state reaction and characterized with X-ray diffraction, photoluminescence emission, photoluminescence excitation spectra and fluorescence decay measurements. When excited with 400 nm, the phosphor gives broadband emission at 560 nm, which corresponds to the allowed 5d → 4f transition of Eu2+ and an intense NIR emissions in the range 800-1400 nm, which are assigned to the characteristic 4I9/2,11/2,13/2 transitions of Nd3+ ions. The dependence of visible and NIR emissions, decay lifetime and the energy transfer efficiency (ηETE) were investigated in detail. The luminescence spectra, both in visible (VIS) and NIR regions, and decay lifetime curves of Eu2+ have been measured to prove energy transfer (ET) from Eu2+ to Nd3+. These results demonstrate the possibility for enhancing the photovoltaic conversion efficiency of silicon solar cell by modifying the absorption and utilizing the UV to blue part of the solar spectrum where the efficiency of c-Silicon solar cell is low.

  13. Inelastic neutron scattering studies on the 3d-4f heterometallic single-molecule magnet Mn2Nd2

    The discovery of slow relaxation and quantum tunneling of the magnetization in Mn12ac more than 15 years ago has inspired both physicists and chemists alike. This class of molecules, now called single-molecule magnets (SMMs), has very recently been expanded to heterometallic clusters incorporating transition metal and rare earth ions. The 4f ions were chosen because of their large angular momentum and magnetic anisotropy. Inelastic neutron scattering experiments were performed on the time-of-flight disk-chopper spectrometer IN5 at ILL on the SMM Mn2Nd2. A magnetic model was developed which perfectly describes all data, including the magnetic data. It was found that neither the large anisotropy nor the large angular momentum of the NdIII ions is the main reason for the SMM behavior in this molecule. Our analysis of the data indicates that it is the weak coupling of the NdIII ions to the MnIII ions, usually considered as a drawback of rare earth ions, which enhances the relaxation time and therefore leads to SMM behavior.

  14. Fuel rod fixing system

    This is a reusable system for fixing a nuclear reactor fuel rod to a support. An interlock cap is fixed to the fuel rod and an interlock strip is fixed to the support. The interlock cap has two opposed fingers, which are shaped so that a base is formed with a body part. The interlock strip has an extension, which is shaped so that this is rigidly fixed to the body part of the base. The fingers of the interlock cap are elastic in bending. To fix it, the interlock cap is pushed longitudinally on to the interlock strip, which causes the extension to bend the fingers open in order to engage with the body part of the base. To remove it, the procedure is reversed. (orig.)

    The spontaneous ionic polymerization of 4-vinyl-pyridine in presence of mono-tosylated or bromated short chains of poly(ethylene oxide)-(PEO) is used to prepare amorphous comb-like poly-cations with low Tg. The polymer electrolyte properties of these new structures have been studied without any addition of salts. The ionic conductivity of these fixed cation poly-electrolytes depends on the length of the grafted PEO and varies from 10{sup -7} to 10{sup -4} S/cm between 25 and 80 deg. C. It is only weakly dependent on the nature of the cation but it is controlled by the movements of the pyridinium cation which are facilitated by the plastifying effect of the POE chains which do not directly participate to the ionic transport.

A number of such operators, generalizing inductive definitions, have been studied in the context of finite model theory, including nondeterministic and alternating operators. We review results established in finite model theory, and also consider the expressive power of the resulting logics on infinite structures. In particular, we establish the relationship between inflationa...

  3. Absorption spectra of CsNd(MoO4)2 and CsGd(MoO4)2-Nd3+ crystals in strong magnetic fields

    The comparison of the electronic structure of Nd3+ in CsNd(MoO4)2 and CsGd(MoO4)2 - Nd3+ crystals is made. It is established that in these crystals the activator centers, mainly, of the certain type with the symmetry of the local environment C2 are formed. The absorption spectra of self-activated CsNd(MoO4)2 crystal differ from spectra of CsGd(MoO4)2 - Nd3+ by the presence of the vibrating structure. The Stark splittings of energy levels of Nd3+ in the investigated crystalline matrices are more sensitive to the environment effect than the Zeeman ones. The ground state of Nd3+ ion in CsNd(MoO4)2 and CsGd(MoO4)2 molybdates is characterized by the similar values of g-factors

  9. Strategies for 2nd generation biofuels in EU - Co-firing to stimulate feedstock supply development and process integration to improve energy efficiency and economic competitiveness

    The present biofuel policies in the European Union primarily stimulate 1st generation biofuels that are produced based on conventional food crops. They may be a distraction from lignocellulose based 2nd generation biofuels - and also from biomass use for heat and electricity - by keeping farmers' attention and significant investments focusing on first generation biofuels and the cultivation of conventional food crops as feedstocks. This article presents two strategies that can contribute to the development of 2nd generation biofuels based on lignocellulosic feedstocks. The integration of gasification-based biofuel plants in district heating systems is one option for increasing the energy efficiency and improving the economic competitiveness of such biofuels. Another option, biomass co-firing with coal, generates high-efficiency biomass electricity and reduces CO2 emissions by replacing coal. It also offers a near-term market for lignocellulosic biomass, which can stimulate development of supply systems for biomass also suitable as feedstock for 2nd generation biofuels. Regardless of the long-term priorities of biomass use for energy, the stimulation of lignocellulosic biomass production by development of near term and cost-effective markets is judged to be a no-regrets strategy for Europe. Strategies that induce a relevant development and exploit existing energy infrastructures in order to reduce risk and reach lower costs, are proposed an attractive complement the present and prospective biofuel policies.

  12. PREFACE: The 2nd International Conference on Geological, Geographical, Aerospace and Earth Sciences 2014 (AeroEarth 2014)

    Lumban Gaol, Ford; Soewito, Benfano

    2015-01-01

    The 2nd International Conference on Geological, Geographical, Aerospace and Earth Sciences 2014 (AeroEarth 2014), was held at Discovery Kartika Plaza Hotel, Kuta, Bali, Indonesia during 11 - 12 October 2014. The AeroEarth 2014 conference aims to bring together researchers and engineers from around the world. Through research and development, earth scientists have the power to preserve the planet's different resource domains by providing expert opinion and information about the forces which make life possible on Earth. Earth provides resources and the exact conditions to make life possible. However, with the advent of technology and industrialization, the Earth's resources are being pushed to the brink of depletion. Non-sustainable industrial practices are not only endangering the supply of the Earth's natural resources, but are also putting burden on life itself by bringing about pollution and climate change. A major role of earth science scholars is to examine the delicate balance between the Earth's resources and the growing demands of industrialization.

  13. Thematic network on the analysis of thorium and its isotopes in workplace materials. Report on the 2nd intercomparison exercise

    Work Package 2 (WP 2) of the EC Thematic Network on ''The analysis of thorium and its isotopes in workplace materials'' is concerned with ''Examination and comparison of analytical techniques for the determination of thorium and its progeny in bulk materials and the development of standards, both for the calibration of associated metrological facilities, and for routine quality control purposes''. The primary objective of WP 2 is ''To evaluate appropriate techniques and determine best practice for analysis of 232Th at workplace levels and environments'', and is to be achieved through a series of intercomparison exercises. Following the results of the 1st intercomparison exercise, a 2nd intercomparison exercise was designed to evaluate the capability of the analytical methods currently being used by European laboratories to determine thorium at very low levels in the presence of a complex inorganic matrix. The intercomparison exercise involved the analysis of three samples of thorium in solution, prepared by the United Kingdom National Physical Laboratory. One sample was the equilibrium solution, analysed in the 1st intercomparison exercise. The other two samples were prepared by dilution of a non-equilibrium thorium solution, one of which was spiked with impurity elements. (i) The results showed a further improvement in the accuracy of measurements in the equilibrium solution, when compared with the results from the 1st intercomparison study. There was an overall drop in u-test values and the number of u-test values above the upper limit of significance fell from 6 to 3. (ii) Overall, participating laboratories also performed well in the analysis of the low level non-equilibrium solutions. However, several laboratories using y-spectrometry had insufficient sensitivity for measurement of low level non-equilibrium sample solutions and did not report results. (iii) There was little evidence that the presence of impurities had a detrimental effect on measurements made

  15. Rhabdomyosarcoma-associated renal cell carcinoma: a link with constitutional Tp53 mutation.

    Curry, Sarah

    2012-02-01

    The 2004 World Health Organization classification includes the new entity "neuroblastoma-associated renal cell carcinoma." The pathogenetic link between these entities is unknown as yet. The patient reported herein developed renal cell carcinoma after anaplastic embryonal rhabdomyosarcoma, a previously unknown association. The 2nd malignancy developed very soon after the 1st one, prompting concern for inherent cancer predisposition rather than a therapy-induced 2nd malignancy. A variety of features raised suspicion for Tp53 mutation, and indeed a pathogenic germline Tp53 mutation was identified in this child, despite a negative family history for Li-Fraumeni syndrome. Consideration of underlying predisposition is advocated in the context of rapid evolution of 2nd childhood malignancy.

  16. Fixing Dataset Search

    Lynnes, Chris

    2014-01-01

    Three current search engines are queried for ozone data at the GES DISC. The results range from sub-optimal to counter-intuitive. We propose a method to fix dataset search by implementing a robust relevancy ranking scheme. The relevancy ranking scheme is based on several heuristics culled from more than 20 years of helping users select datasets.

    2010-06-01

    Full Text Available One of the main socio-economic problems in Russia is the high cost and the poor condition of housing.Such goals as cost reduction, reducing installation time and increasing the service life of structures are accomplishing by creating new technologies of erecting buildings and developing ways ofquickconstruction, using different types of fixed formwork. One of themis textstone.Textstone is an artificial construction stone, containing on the outer surface the reinforcing fine-mesh shell with multifunctional properties, formed by the interwoven threads of a vigorous fixed formwork textile material (basalt, linen, silica and other glass yarns adhered by binding material. The innovative construction technology of production and installation of a new generation of textstone buildings has been registered as a brand TextStone. The fundamental difference between texstone and reinforced concrete and all known building materials is that the whole outer surface of solidified light binders is protected by strong, vigorous and fixed formwork made from inexpensive textile materials. Manufacturing textile shells allows using it as an internal finishing material, reducing or eliminating the cost of finishing work.The use of fixed textile construction shutters during the construction of buildings has obvious technical, economic, operational, sanitary and environmental benefits: short construction time (from 3 to 10 days, compact packaging and light weight of fabric shells, high fire resistance, frost resistance, ease of engineering services installation in the hollow communicating shells; minimal amount of finishing, roofing, heat and noise insulation works. Texstone is a durable solid monolithic construction that provides high viability and earthquakes, hurricanes wind, solar sultriness and frost resistance. Material complies with all sanitary and environmental requirements. Due to such physical, mechanical, operational, sanitary and ecological characteristics

    2013-01-01

    The concept of a fixed field alternating gradient (FFAG) accelerator was invented in the 1950s. Although many studies were carried out up to the late 1960s, there has been relatively little progress until recently, when it received widespread attention as a type of accelerator suitable for very fast acceleration and for generating high-power beams. In this paper, we describe the principles and design procedure of a FFAG accelerator.

    Full Text Available Background: Geographic tongue (GT was first reported as a wandering rash of the tongue in 1831; however, its etiopathogenesis remains unclear. Increased prevalence of GT has been documented in the pregnancy. The aim of this study was to compare the level of salivary estrogen and progesterone in pregnant women with and without GT. Materials and Methods: This analytical-descriptive study consisted of 26 pregnant women (13 with GT, 13 without GT with an age range between 18 years and 45 years. The estrogen and progesterone level was measured during 1 st , 2 nd and 3 rd trimester of pregnancy. Saliva sampling was performed to determine the level of sex hormones. The samples were stored at -80°C and determined by Eliza method. The results were analyzed by t-test and repeated measure ANOVA (α = 0.05. Results: The mean level of estrogen for control and case group was 49.4and 52.33 in the 1 st , 71.05 and 74.12 in the 2 nd and 109.1 and 112.16 in the 3 rd trimester respectively. The mean level of progesterone was 0.72 and 0.72 in the 1 st , 1.14 and 1.21 in the 2 nd and 1.3 and 1.28 in the 3 rd trimester of pregnancy for the control and case groups respectively. Even though, there was no significant difference regarding the level of sex hormones between case and control groups (P > 0.05, but the difference between the level of these hormones during 3 trimesters of pregnancy was significant in each group (P = 0.001. Conclusion: The level of sex hormones is not the only etiologic factor of GT in pregnant women, but other factors such as genetic potential, human leukocyte antigen marker and stress may aggravate the incidence of this lesion.

  2. Characterization of the 1st and 2nd EF-hands of NADPH oxidase 5 by fluorescence, isothermal titration calorimetry, and circular dichroism

    Full Text Available Abstract Background Superoxide generated by non-phagocytic NADPH oxidases (NOXs is of growing importance for physiology and pathobiology. The calcium binding domain (CaBD of NOX5 contains four EF-hands, each binding one calcium ion. To better understand the metal binding properties of the 1st and 2nd EF-hands, we characterized the N-terminal half of CaBD (NCaBD and its calcium-binding knockout mutants. Results The isothermal titration calorimetry measurement for NCaBD reveals that the calcium binding of two EF-hands are loosely associated with each other and can be treated as independent binding events. However, the Ca2+ binding studies on NCaBD(E31Q and NCaBD(E63Q showed their binding constants to be 6.5 × 105 and 5.0 × 102 M-1 with ΔHs of -14 and -4 kJ/mol, respectively, suggesting that intrinsic calcium binding for the 1st non-canonical EF-hand is largely enhanced by the binding of Ca2+ to the 2nd canonical EF-hand. The fluorescence quenching and CD spectra support a conformational change upon Ca2+ binding, which changes Trp residues toward a more non-polar and exposed environment and also increases its α-helix secondary structure content. All measurements exclude Mg2+-binding in NCaBD. Conclusions We demonstrated that the 1st non-canonical EF-hand of NOX5 has very weak Ca2+ binding affinity compared with the 2nd canonical EF-hand. Both EF-hands interact with each other in a cooperative manner to enhance their Ca2+ binding affinity. Our characterization reveals that the two EF-hands in the N-terminal NOX5 are Ca2+ specific.

  11. [Influence of hypocaloric diet with addition of a vitamin-mineral complex on status of patients with obesity 1st and 2nd degrees].

    Sharafetdinov, Kh Kh; Plotnikova, O A; Zykina, V V; Mal'tsev, G Iu; Sokol'nikov, A A; Kaganov, B S

    2011-01-01

    Addition of a vitamin-mineral complex (VMC) to a standard hypocaloric diet leads to a positive dynamics of antropometric characteristics in patients with obesity 1st and 2nd degrees which is comparable to effectiveness of standard dietotherapy (dietary treatment) traditionally used in complex treatment of obesity. Addition of 1,8 mg of vitamin B2 as part of VMC to a hypocaloric diet is shown to be inadequate in eradication of marginal provision of riboflavin when using diets reduced in calories. PMID:22232885

    BaAl{sub 2}O{sub 4}:Eu{sup 2+},Nd{sup 3+},Gd{sup 3+} phosphors were prepared by a combustion method at different initiating temperatures (400-1200 Degree-Sign C), using urea as a comburent. The powders were annealed at different temperatures in the range of 400-1100 Degree-Sign C for 3 h. X-ray diffraction data show that the crystallinity of the BaAl{sub 2}O{sub 4} structure greatly improved with increasing annealing temperature. Blue-green photoluminescence, with persistent/long afterglow, was observed at 498 nm. This emission was attributed to the 4f{sup 6}5d{sup 1}-4f{sup 7} transitions of Eu{sup 2+} ions. The phosphorescence decay curves were obtained by irradiating the samples with a 365 nm UV light. The glow curves of the as-prepared and the annealed samples were investigated in this study. The thermoluminescent (TL) glow peaks of the samples prepared at 600 Degree-Sign C and 1200 Degree-Sign C were both stable at {approx}72 Degree-Sign C suggesting that the traps responsible for the bands were fixed at this position irrespective of annealing temperature. These bands are at a similar position, which suggests that the traps responsible for these bands are similar. The rate of decay of the sample annealed at 600 Degree-Sign C was faster than that of the sample prepared at 1200 Degree-Sign C.

    The 2nd International Conference on Particle Physics in memoriam Engin Arık and her Colleagues: Fatma Şenel Boydağ, İskender Hikmet, Mustafa Fidan, Berkol Doğan and Engin Abat was held at Doğuş University, İstanbul, Turkey on 20-25 June 2011. The conference was organized jointly by the Doğuş and Boğaziçi Universities, with support from CERN and the Turkish Academy of Sciences. This was the second International Conference on Particle Physics (ICPP) organized in memory of Engin Arık and her Colleagues who lost their lives in the tragic plane accident on November 30 2007, on their way to the workshop of the Turkish Accelerator Center (TAC) Project. The first of this conference series was held on 27-31 October 2008 at Boğaziçi University, İstanbul, Turkey. The conference is intended to be repeated every two years in Istanbul as a Conference Series under the name 'ICPP-Istanbul'. Professor Engin Arık had a pioneering role in experimental particle physics in Turkey, and was an inspiring teacher to many colleagues. She led the Turkish participation in experiments at CERN such as CHARMII, SMC, CHORUS, ATLAS and CAST. One of her latest involvements was in the national project to design the Turkish Accelerator Center with the collaboration of 10 Turkish universities including Doğuş and Boğaziçi. Our dear colleagues not only participated in the TAC project but also collaborated on the ATLAS (E Arık, E Abat and B Doğan) and CAST (E Arık, F Şenel Boydağ, İ Hikmet and B Doğan) experiments. We believe that the ICPP-Istanbul conference series has been, and will always be, a way to commemorate them in a most appropriate context. The topics covered in ICPP-Istanbul-II were 'LHC Physics and Tevatron Results', 'Neutrinos and Dark Matter', 'Particle Factories' and 'Accelerator Physics and Future TeV Scale Colliders'. The main emphasis was on the recent experimental results in high-energy physics with discussions on expectations from existing or future

At the end of research students’ views about computer assisted mathematics instruction were evaluated. It has been examined that whether the differences between the scores of pre-test and post-test are statistically meaningful or not. According to the results, a positive increase on the academic achievement and problem solving skills has been determined at the end of the education carried out with STAR strategy.

  16. Structural and magnetic study of order-disorder behavior in the double perovskites Ba2Nd1-xMnxMoO6.

    Coomer, Fiona C; Cussen, Edmund J

    2014-01-21

    The synthesis and structural and magnetic characterization of the site-ordered double perovskites, Ba2Nd1-xMnxMoO6, 0 0.3, no deviation from the ideal cubic Fm3̅m symmetry is observed. Furthermore, dc-susceptibility measurements confirm that Mn(2+) is being doped onto the Nd(3+) site, and the associated oxidation of Mo(5+) to Mo(6+). For all compositions, the Curie-Weiss paramagnetic behavior above 150 K indicates negative Weiss constants that range from -24(2) and -85(2) K. This net antiferromagnetic interaction is weakest when x ≈ 0.5, where the disorder in cation site occupancy and competition with ferromagnetic interactions is the greatest. Despite these strong antiferromagnetic interactions, there is no evidence in the dc-susceptibility of a bulk cancellation of spins for x > 0.05. Low-temperature neutron diffraction measurements indicate that there is no long-range magnetic order for 0.1 ≤ x < 0.9. Ba2Nd0.10Mn0.90MoO6 exhibits additional Bragg scattering at 2 K, indicative of long-range antiferromagnetic ordering of the Mn(2+) cations, with a propagation vector k = (1/2, 1/2, 1/2). The scattering intensities can be modeled using a noncollinear magnetic structure with the Mn(2+) moments orientated antiferromagnetically along the four different ⟨111⟩ directions. PMID:24392887

    2006-05-14

    Oscillator strengths of the 2p{sup 5}({sup 2}P{sub 1/2})nd J = 2, 3 autoionizing resonances in neon have been determined using a dc discharge plasma in conjunction with an Nd:YAG pumped dye laser system. The excited states are approached using two-step laser excitation via 2p{sup 5}3p'[1/2]{sub 1}, 2p{sup 5}3p'[3/2]{sub 1} and 2p{sup 5}3p'[3/2]{sub 2} intermediate states which are accessed from the 2p{sup 5}3s [1/2]{sub 2} metastable state, populated by the discharge in the hollow cathode lamp. The f-values have been determined for the nd'[3/2]{sub 2}, nd'[5/2]{sub 2} and nd'[5/2]{sub 3} series following the {delta}K = {delta}J = +{delta}l selection rule. Employing the saturation technique the photoionization cross section at the 2p{sup 5} {sup 2}P{sub 1/2} ionization threshold is determined as 5.5(6) Mb and consequently the f-values of the nd' J = 2, 3 autoionizing resonances have been extracted.

  18. Hyperfine structure and lifetime measurements in the 4s2nd 2D3/2 Rydberg sequence of Ga I by time-resolved laser spectroscopy

    Liu, Chunqing; Tian, Yanshan; Yu, Qi; Bai, Wanshuang; Wang, Xinghao; Wang, Chong; Dai, Zhenwen

    2016-05-01

    The hyperfine structure (HFS) constants of the 4s2nd 2D3/2 (n=6-18) Rydberg sequence and the 4s26p 2P3/2 level for two isotopes of 69Ga and 71Ga atoms were measured by means of the time-resolved laser-induced fluorescence (TR-LIF) technique and the quantum beat method. The observed hyperfine quantum beat spectra were analyzed and the magnetic-dipole HFS constants A as well as the electric-quadrupole HFS constants B of these levels were obtained by Fourier transform and a program for multiple regression analysis. Also using TR-LIF method radiative lifetimes of the above sequence states were determined at room temperature. The measured lifetime values range from 69 to 2279 ns with uncertainties no more than 10%. To our knowledge, the HFS constants of this Rydberg sequence and the lifetimes of the 4s2nd 2D3/2 (n=10-18) levels are reported for the first time. Good agreement between our results and the previous is achieved.

  19. Carbon dioxide emissions and the overshoot ratio change resulting from the implementation of 2nd Energy Master Plan in South Korea

    Yeo, M. J.; Kim, Y. P.

    2015-12-01

    The direction of the energy policies of the country is important in the projection of environmental impacts of the country. The greenhouse gases (GHGs) emission of the energy sector in South Korea is very huge, about 600 MtCO2e in 2011. Also the carbon footprint due to the energy consumption contributes to the ecological footprint is also large, more than 60%. Based on the official plans (the national greenhouse gases emission reduction target for 2030 (GHG target for 2030) and the 2nd Energy Master Plan (2nd EMP)), several scenarios were proposed and the sensitivity of the GHG emission amount and 'overshoot ratio' which is the ratio of ecological footprint to biocapacity were estimated. It was found that to meet the GHG target for 2030 the ratio of non-emission energy for power generation should be over 71% which would be very difficult. We also found that the overshoot ratio would increase from 5.9 in 2009 to 7.6 in 2035. Thus, additional efforts are required to reduce the environmental burdens in addition to optimize the power mix configuration. One example is the conversion efficiency in power generation. If the conversion efficiency in power generation rises up 50% from the current level, 40%, the energy demand and resultant carbon dioxide emissions would decrease about 10%. Also the influence on the environment through changes in consumption behavior, for example, the diet choice is expected to be meaningful.

    Full Text Available The course of Life Sciences is one of the pivot courses taught in the first three years of primary school. Ensuring children get to know their environment and gain correct information related to their problems by making them investigate their natural and socio-cultural environment as well as providing them with necessary information, skills and behaviors for environmental adaptation are among the main purposes of Life Sciences course. The concepts to be instilled in students in line with these purposes are important. Since concepts are mostly intellectual and non-physical, they can only exist tangibly through examples. This study aims to assess Primary School Students’ Level of Understanding the Concepts of 2nd Grade Life Sciences Course Based on Different Variables. 17 concepts included in the 2nd Grade Life Sciences course within the subject of School Excitement were addressed within the study, and students were requested to define and exemplify these concepts. A total of 102 students from five different primary schools of upper-middle and lower socioeconomic classes located in Manisa and Istanbul were included in the study in line with the intentional maximum diversity sample selection. The answers given by students for each concept were categorized and analyzed in terms of liking or disliking home, school, technology and the course of Life Sciences.

  3. Fixed telephony evolution at CERN

    CERN. Geneva

    2015-01-01

    The heart of CERN’s telephony infrastructure consists of the Alcatel IP-PBX that links CERN’s fixed line phones, Lync softphones and CERN’s GSM subscribers to low-cost local and international telephony services. The PABX infrastructure also supports the emergency “red telephones” in the LHC tunnel and provides vital services for the Fire and Rescue Service and the CERN Control Centre. Although still reliable, the Alcatel hardware is increasingly costly to maintain and looking increasingly outmoded in a market where open source solutions are increasingly dominant. After presenting an overview of the Alcatel PABX and the services it provides, including innovative solutions such as the Closed User Group for our mobile telephony services, we present a possible architecture for a software based system designed to meet tomorrow’s communication needs and describe how the introduction of open-source call routers based on the SIP protocol and Session Border Controllers (SBC) could foster the introduction...

  4. Fixed term employment

    A series of brief notes were included with this presentation which highlighted certain aspects of contract management. Several petroleum companies have realized the benefits of taking advantage of contract personnel to control fixed G and A, manage the impacts on their organization, contain costs, to manage termination costs, and to fill gaps in lean personnel rosters. An independent contractor was described as being someone who is self employed, often with a variety of work experiences. The tax benefits and flexibility of contractor personnel were also described. Some liability aspects of hiring an independent contractor were also reviewed. The courts have developed the following 4 tests to help determine whether an individual is an employee or an independent contractor: (1) the control test, (2) the business integration test, (3) specific result test, and (4) the economic reality test

  5. Fixed Access Network Sharing

    Cornaglia, Bruno; Young, Gavin; Marchetta, Antonio

    2015-12-01

    Fixed broadband network deployments are moving inexorably to the use of Next Generation Access (NGA) technologies and architectures. These NGA deployments involve building fiber infrastructure increasingly closer to the customer in order to increase the proportion of fiber on the customer's access connection (Fibre-To-The-Home/Building/Door/Cabinet… i.e. FTTx). This increases the speed of services that can be sold and will be increasingly required to meet the demands of new generations of video services as we evolve from HDTV to "Ultra-HD TV" with 4k and 8k lines of video resolution. However, building fiber access networks is a costly endeavor. It requires significant capital in order to cover any significant geographic coverage. Hence many companies are forming partnerships and joint-ventures in order to share the NGA network construction costs. One form of such a partnership involves two companies agreeing to each build to cover a certain geographic area and then "cross-selling" NGA products to each other in order to access customers within their partner's footprint (NGA coverage area). This is tantamount to a bi-lateral wholesale partnership. The concept of Fixed Access Network Sharing (FANS) is to address the possibility of sharing infrastructure with a high degree of flexibility for all network operators involved. By providing greater configuration control over the NGA network infrastructure, the service provider has a greater ability to define the network and hence to define their product capabilities at the active layer. This gives the service provider partners greater product development autonomy plus the ability to differentiate from each other at the active network layer.

  6. Fixed points for multi-class queues

    Martin, James B

    2010-01-01

    Burke's theorem can be seen as a fixed-point result for an exponential single-server queue; when the arrival process is Poisson, the departure process has the same distribution as the arrival process. We consider extensions of this result to multi-type queues, in which different types of customer have different levels of priority. We work with a model of a queueing server which includes discrete-time and continuous-time M/M/1 queues as well as queues with exponential or geometric service batches occurring in discrete time or at points of a Poisson process. The fixed-point results are proved using interchangeability properties for queues in tandem, which have previously been established for one-type M/M/1 systems. Some of the fixed-point results have previously been derived as a consequence of the construction of stationary distributions for multi-type interacting particle systems, and we explain the links between the two frameworks. The fixed points have interesting "clustering" properties for lower-priority ...

  7. Construction of real-type simulator reusing the equipment of the Musashi-reactor. The 2nd report

    Real-time reactor simulator had been developed with reusing control rod drive and operation console, and simulated fuel elements and grid plate of the Musashi reactor. Type of the fuel element and its location in the core were identified through electric circuits. Core characteristics such as excess reactivity, control rod worths and temperature effects were reproduced on a personal computer using the actual operation data of the Musashi Reactor. Operation of control rod, core characteristics, core configuration and instrumentation data were mutually linked and controlled by the interface. Effect of delayed neutrons and simulated reactivity insertion accident could be demonstrated with the application software installed. The simulator was incorporated in the curriculum. (T. Tanaka)

    This report describes a neutron fluence assessment performed for the Yonggwang Unit 1 pressure vessel belt line region based on the guidance specified in Regulatory Guide 1.190. In this assessment, maximum fast neutron exposures expressed in terms of fast neutron fluence (E>1 MeV) and iron atom displacements (dpa) were established for the belt line region of the pressure vessel. During Cycle 16 of reactor operation, 2nd Ex-Vessel Neutron Dosimetry Program was instituted at Yonggwang Unit 1 to provide continuous monitoring of the belt line region of the reactor vessel. The use of the Ex-Vessel Neutron Dosimetry Program coupled with available surveillance capsule measurements provides a plant specific data base that enables the evaluation of the vessel exposure and the uncertainty associated with that exposure over the service life of the unit. Ex-Vessel Neutron Dosimetry has been evaluated at the conclusion of Cycle 16.

    2016-03-01

    CaO-SiO2-Nd2O3 slags were equilibrated at 1773 K and 1873 K (1500 °C and 1600 °C) for 24 hours in Ar, and quenched in water to determine the operative phase relations. The composition and crystallinity of the phases in equilibrium were determined by EPMA-WDS and EBSD, respectively. Based on these analyses, the liquid stability region was accurately determined, and a large part of the isothermal section of the phase diagram was constructed. Data resulting from this work can be used to generate a thermodynamic database for rare-earth oxide-containing systems and to support further investigation on separation of rare earths from metallurgical slags or other residues through high-temperature processing.

  14. An Analysis of Chinglish in Press Conference Interpretation-Case Study on the In-terpretation of the 2nd guangdong International Consultative Conference (GICC)

    王珊

    2014-01-01

    This thesis aims at analyzing the Chinglish in press conference interpretation with context adaptation of Belgian lin-guist Jef Verschueren’s Adaptation Theory as the theoretical framework. In Adaptation Theory, context includes all kinds of fac-tors that concern the environment in which the communication takes place, with non-linguistic factors like the physical world, the social world and the mental world playing an important role. Taking the press conference interpretation of the 2nd Guang-dong International Consultative Conference as an example, the author attempts to prove the presumption that Adaptation Theory can be applied to spot and reduce the Chinglish in interpreting. It is concluded that the theory of adaptation to the mental world and social world can be applied to reduce the Chinglish of two particular kinds to the minimum level and achieve successful com-munication.

  18. Synthesis and characterization of new cuprates (Pb0.75Mo0.25)Sr2(Nd1-xCax)Cu2O7-δ

    New cuprates with nominal composition (Pb0.75Mo0.25)Sr2(Nd1-xCax)Cu2O7-δ (0 ≤ x ≤ 1) were synthesized by solid state reactions in N2. The crystal structure was characterized by x-ray powder diffraction as tetragonal. Dc electrical resistance and ac magnetic susceptibility measurements were applied to check the existence of superconductivity in these cuprates. Superconductivity with Tc up to 73 K is observed in the range 0.4 ≤ x ≤ 0.6. Synthesis in N2 is found to be necessary for obtaining superconductivity in these cuprates. Preparation in air or post-treatment in flowing oxygen destroys superconductivity. Comparison with previous Pb-based 1212 superconducting oxides is made. The valence of Pb and the possible position of Mo in the lattice are discussed. (author)

  20. Phases of variable composition in the Ca3(VO4)2-NdVO4 - Na3VO4 system

    Phase equilibriums in the Ca3(VO4)2 - NdVO4-Na3VO4 system are studied. Formation of variable composition phases on the base of calcium orthovanadate is established. The field of variable composition phase is placed inside of Ca3(VO4)2 - Ca9Nd□(VO4)7 - Ca10Na(VO4)7 - Ca8NdNa2(VO4)7 (Z = 6) quadrangle. Boundary compositions are determined by structure of low temperature modification of Ca3(VO4)2 (Z = 21, sp. gr. R3c). The degree of Ca(4) positions occupancy has influence on phase transition temperature, ionic conductivity and parameters of IR- and CS-spectra. Considerable growth of the conductivity higher than 650 K on the calcium ions is explained by order-disorder transformation associated with disproportional of structural vacancies (□) on different cation positions

  3. Cardiolipin as key lipid of mitochondria in health and disease. 2nd Edition, Florence, Italy, September 30-October 1, 2015.

    Corcelli, Angela; Schlame, Michael

    2016-06-01

    The second edition of the workshop dedicated to cardiolipin, the signature lipid of mitochondria, was held as a satellite meeting of the 13th Euro Fed Lipid international congress in Florence, Italy, at the end of September 2015. During the workshop various aspects of basic cardiolipin functions in biomembranes of prokaryotes and animal cells were discussed, highlighting connections between cardiolipin research and human physiology in particular. Alteration of the cardiolipin species pattern and a parallel increase of monolysocardiolipin is the hallmark of Barth syndrome, an X linked genetic disease. Furthermore literature reports suggest the involvement of cardiolipin in other pathologies associated with an imbalance in bioenergetic functions, such as diabetes. The Cardiolipin Workshop was a low budget meeting sponsored by the University of Bari Aldo Moro and the Barth Syndrome Foundation. The organizers are grateful to the invited speakers, poster presenters and chairpersons as they supported the meeting by sustaining their travel and lodging expenses. Before the starting of the scientific sessions, the families of Italian boys affected by Barth syndrome (recently affiliated with the Barth Syndrome Foundation, USA) could meet scientists, biologists and pediatricians involved in research, diagnosis and cure of the disease. The family meeting was chaired by Daniela Toniolo, who discovered the tafazzin gene in 1997. PMID:27132118

    This research has as a target the inquiry about the contribution of the organization of catholic sport to help the development of the national sport system. From the privileged relation given by the Pope Pacelli to the catholic sporting people, working out with his speeches a conception of «Christianly and healthily intense» sport, able to guide and direct them in facing this phenomenon in continuous expansion. To the introduction of Luigi Gedda’s character, the president of the ISC from 1944, the year of its foundation, until 1960, the year of the XVII Olympiad in Rome, who represents the union link between the ecclesiastical hierarchy, the ISC and the sport. To the activity of the ISC in the 50s, when a substantial development of its pledge and its activities has been seen in front of the sporting youth, made concrete through a higher number of federated ones. But specially to the working behavior developed before by this catholic organization facing the Olympic Games of Rome in 1960, with the preparation of the Olympic Journey designed by the INOC for spreading the Olympic spirit among population in all places of Italy and for requesting the development of a critical awareness in front of the Italians’ high motive illiteracy.

  5. PREVALENCE OF DEPRESSION, ANXIETY AND STRESS: A CROSS-SECTIONAL SURVEY AMONG 2ND YEAR MEDICAL STUDENTS IN A RURAL TERTIARY CARE CENTRE

    Full Text Available BACKGROUND Medical education is highly stressful and higher stress has been documented in medical students. Stepping entirely into a new environment, huge medical course syllabus which has to be mastered in a short period of time, continuous internal assessments, examinations, being far from family and other social and personal issues are more prone to develop negative emotional symptoms to a newly joined student. OBJECTIVE To determine the prevalence of depression, anxiety and stress among 2nd year medical students at AIMS, B G Nagar. METHODS A cross-sectional questionnaire-based study was conducted among 2nd year medical students of AIMS, B G Nagar. RESULTS Among 185 students 160 students had completed the questionnaire, the response rate was 86.46%; 118 were female students (73.75% and 42 were male students (26.25% and were within the age group of 19 to 21 years. In our study 41.87% of students showed depression, 68.12% of students showed anxiety and 63.12% of students showed stress of different grades (Mild, moderate, severe and very severe. The incidence of depression was almost similar in both the gender and the incidence of anxiety and stress were more among females. CONCLUSION In our study, the prevalence of anxiety and stress is more in medical students. Females are more anxious and stressful than males. Early interventions and timely monitoring should be done to address these negative emotional symptoms. Counselling of students, workshops on stress management, daily physical activities could help them to come out of these health issues.

  6. Construction and cost experience regarding the 2nd pool house for spent fuel storage facility in the Atucha Power Station

    The Atucha I second pool house storage for spent fuel is designed as an extension of the Atucha I power station. The two are linked by civil structure, controlling circuits, electrical and compressed air and water supplies, low level wastes disposal, ventilation under pressure maintenance, and, most important, the ability to transfer spent and new fuel in both directions. Because the second pool house is, by location and design, an extension of the existing installation, and since there is no design departure, regarding storage and transfer of fuel from that of the original installation, the rules and regulations applied for its construction were the same as those valid for the Atucha I construction. The requirement not to exceed a four-year period for construction and commissioning was determined by the need to have storage room for the Atucha I fuel. Argentina will meet the 1982 target by having the installation available during the second half of 1981. The second pool house is a wet storage location with a capacity of 1000 tons metallic uranium. It was designed by the Kraftwerk Union of West Germany along the same lines as the 440-ton storage location originally built with the station. The Atomic Energy Commission of Argentina has managed the construction and participated in project and design stages. As in the original pool, the 6 m long assemblies are stacked in double tiers. The cost figures which are mentioned differ from previously released figures and are not the final ones. With civil construction almost finished and mechanical erection started, the present estimates should not differ by more than 10% from the final figures. The installation has an investment cost of 61 million dollars, (1980), and, depending on the amortization time span considered, a total yearly cost per kg of capacity of metallic uranium, ranging between 5.5 and 9.3 dollars per kg

    The supersymmetric model developed by Witten (1982 J. Differ. Geom. 17 661-92) to study the equivariant cohomology of a manifold with an isometric circle action is derived from the BRST quantization of a simple classical model. The gauge-fixing process is carefully analysed, and demonstrates that different choices of gauge-fixing fermion can lead to different quantum theories.

  11. A neutron diffraction study of structural distortion and magnetic ordering in the cation-ordered perovskites Ba2Nd1−xYxMoO6

    The cation ordered perovskites Ba2Nd1−xYxMoO6 (0.04≤x≤0.35) have been synthesised by solid-state techniques under reducing conditions at temperatures up to 1350 °C. Rietveld analyses of X-ray and neutron powder diffraction data show that these compounds adopt a tetragonally distorted perovskite structure. The tetragonal distortion is driven by the bonding requirements of the Ba2+ cation that occupies the central interstice of the perovskite; this cation would be underbonded if these compounds retained the cubic symmetry exhibited by the prototypical structure. The size and charge difference between the lanthanides and Mo5+ lead to complete ordering of the cations to give a rock-salt ordering of Nd3+/Y3+O6 and MoO6 octahedra. The I4/m space group symmetry is retained on cooling the x=0.1, 0.2 and 0.35 samples to low temperature ca. 2 K. Ba2Nd0.90Y0.10MoO6 undergoes a gradual distortion of the MoO6 units on cooling from room temperature to give two long trans bonds (2.001(2) Å) along the z-direction and four shorter apical bonds (1.9563(13) Å) in the xy-plane. This distortion of the MoO6 units stabilises the 4d1 electron in the dxz and dyz orbitals whilst the dxy orbital is increased in energy due to the contraction of the Mo–O bonds in the xy-plane. This bond extension along z is propagated through the structure and gives a negative thermal expansion of −13×10−6 K−1 along c. The overall volumetric thermal expansion is positive due to conventional expansion along the other two crystallographic axes. With increasing Y3+ content this distortion is reduced in x=0.2 and eliminated in x=0.35 which contains largely regular MoO6 octahedra. The x=0.1 and x=0.2 show small peaks in the neutron diffraction profile due to long range antiferromagnetic order arising from ordered moments of ca. 2 μB. - Graphical Abstract: The distortion in the molybdenum crystal field is continuously adjusted by chemical composition of the perovskite.

    Full Text Available Abstract God created human as caliph on this earth. Caliph means leader, care-taker and guardian. Therefore humans have an obligation to maintain, preserve and conserve this natural for future generations. Today we see a lot of damage that occurs in the earth caused by human behavior. Islam saw the whole of nature as a place of prayer that must be maintained its cleanliness and purity. Therefore as Muslims we need to preserve nature as we keep our place of prayer. The main objective of this paper is to re-questioning and re-interpreting the idea of sustainability in Islamic Architecture through a critical analysis of first project of 2nd year architecture student of UKM which is the “Temporary Praying Platform”. The discussion itself will be divided into three (3 main parts. The first part will be discussing contemporary issues in Islamic Architecture especially in the design of Mosques while the second part will expand the framework of sustainability in Islamic Architecture. The last part will be analyzing some sample of design submission by 2nd year students of UKM on the temporary praying platform project. It is expected that this paper can start a further discussion on the inner meaning in Islam and how it was implemented in the design of praying spaces in the future.

  16. CERN: Fixed target targets

    Full text: While the immediate priority of CERN's research programme is to exploit to the full the world's largest accelerator, the LEP electron-positron collider and its concomitant LEP200 energy upgrade (January, page 1), CERN is also mindful of its long tradition of diversified research. Away from LEP and preparations for the LHC proton-proton collider to be built above LEP in the same 27-kilometre tunnel, CERN is also preparing for a new generation of heavy ion experiments using a new source, providing heavier ions (April 1992, page 8), with first physics expected next year. CERN's smallest accelerator, the LEAR Low Energy Antiproton Ring continues to cover a wide range of research topics, and saw a record number of hours of operation in 1992. The new ISOLDE on-line isotope separator was inaugurated last year (July, page 5) and physics is already underway. The remaining effort concentrates around fixed target experiments at the SPS synchrotron, which formed the main thrust of CERN's research during the late 1970s. With the SPS and LEAR now approaching middle age, their research future was extensively studied last year. Broadly, a vigorous SPS programme looks assured until at least the end of 1995. Decisions for the longer term future of the West Experimental Area of the SPS will have to take into account the heavy demand for test beams from work towards experiments at big colliders, both at CERN and elsewhere. The North Experimental Area is the scene of larger experiments with longer lead times. Several more years of LEAR exploitation are already in the pipeline, but for the longer term, the ambitious Superlear project for a superconducting ring (January 1992, page 7) did not catch on. Neutrino physics has a long tradition at CERN, and this continues with the preparations for two major projects, the Chorus and Nomad experiments (November 1991, page 7), to start next year in the West Area. Delicate neutrino oscillation effects could become

  17. A Fixed-point Scheme for the Numerical Construction of Magnetohydrostatic Atmospheres in Three Dimensions

    Gilchrist, S A; Barnes, G

    2016-01-01

    Magnetohydrostatic models of the solar atmosphere are often based on idealized analytic solutions because the underlying equations are too difficult to solve in full generality. Numerical approaches, too, are often limited in scope and have tended to focus on the two dimensional problem. In this article we develop a numerical method for solving the nonlinear magnetohydrostatic equations in three dimensions. Our method is a fixed-point iteration scheme that extends the method of Grad and Rubin (Proc. 2nd Int. Conf. on Peaceful Uses of Atomic Energy 31, 190, 1958) to include a finite gravity force. We apply the method to a test case to demonstrate the method in general and our implementation in code in particular.

    Full Text Available A bridge between clinical and basic science aiming at cross fertilization, with leading experts presenting alongside junior investigators, is the key feature of the “2nd Florence International Symposium on Advances in Cardiomyopathies” , 9th Meeting of the Myocardial and Pericardial Diseases Working Group of the European Society of Cardiology, which was held in Florence, Italy on 26-­-28th September 2012. Patients with cardiomyopathies, with an estimated 3 per thousand prevalence in the general population, constitute an increasingly large proportion of patients seen by most cardiologists. This class of diseases, which are mostly genetically determined with different transmission modalities, can cause important and often unsolved management problems, despite rapid advances in the field. On the other hand, few other areas of cardiology have seen such an impressive contribution from basic science and translational research to the understanding of their pathophysiology and clinical management. The course was designed to constantly promote close interaction between basic science and clinical practice and highlight the top scientific and translational discoveries in this field in 10 scientific sessions. It was preceded by two mini-­-courses, which included the basic concepts of cardiomyocyte mechanical and electrophysiological properties and mechanisms, how-­-to sessions for clinical diagnosis and management and illustrative case study presentations of different cardiomyopathies.

    Full Text Available The experimental investigation of 2nd generation bioethanol derived from EFB of oil-palm blended with gasoline for 10, 20, 25% by volume and pure gasoline were conducted on performance and exhaust emission tests of SI engine. A four stroke, four cylinders, programmed fuel injection (PGMFI, 16 valves variable valve timing and electronic lift control (VTEC, single overhead camshaft (SOHC, and 1,497 cm3 SI engine (Honda/L15A was used in this investigation. Engine performance test was carried out for brake torque, power, and fuel consumption. The exhaust emission was analyzed for carbon monoxide (CO and hydrocarbon (HC. The engine was operated on speed range from1,500 until 4,500 rev/min with 85% throttle opening position. The results showed that the highest brake torque of bioethanol blends achieved by 10% bioethanol content at 3,000 to 4,500 rpm, the brake power was greater than pure gasoline at 3,500 to 4,500 rpm for 10% bioethanol, and bioethanol-gasoline blends of 10 and 20% resulted greater bsfc than pure gasoline at low speed from 1,500 to 3,500 rpm. The trend of CO and HC emissions tended to decrease when the engine speed increased.

    The discovery of slow relaxation and quantum tunneling of the magnetization in Mn{sub 1}2ac more than 15 years ago has inspired both physicists and chemists alike. This class of molecules, now called single-molecule magnets (SMMs), has very recently been expanded to heterometallic clusters incorporating transition metal and rare earth ions. The 4f ions were chosen because of their large angular momentum and magnetic anisotropy. Inelastic neutron scattering experiments were performed on the time-of-flight disk-chopper spectrometer IN5 at ILL on the SMM Mn{sub 2}Nd{sub 2}. A magnetic model was developed which perfectly describes all data, including the magnetic data. It was found that neither the large anisotropy nor the large angular momentum of the Nd{sup I}II ions is the main reason for the SMM behavior in this molecule. Our analysis of the data indicates that it is the weak coupling of the Nd{sup I}II ions to the Mn{sup I}II ions, usually considered as a drawback of rare earth ions, which enhances the relaxation time and therefore leads to SMM behavior.

    The long afterglow phosphor CaAl2O4:Eu2+,Nd3+ was prepared by the high temperature solid-state reaction method,and the influence of La3+ and Dy3+ on the properties of the long afterglow phosphor was studied by X-ray diffraction (XRD),photoluminescence (PL),and thermoluminescence (TL),The XRD pattern shows the host phase of CaAl2O4 is produced and no impurity phase appears.The peak wavelength of the phosphor does not vary with La3+ and Dy3+ doping.It implies that the crystal field,which affects the 5d electron states of Eu2+ is not changed dramatically after doping of La3+ and Dy3+.The TL spectra indicate that the phosphor doped with La3+ or Dy3+ produces different depths of trap energy level.In the mechanism of long afterglow luminescence,it is considered that La3+ or Dy3+ works as trap energy level.The decay time lies on the number of electrons in the trap energy level and the rate of the electrons returning to the excitation level.

    The use of laser produced plasmas (LPPs) in extreme ultraviolet/soft x-ray lithography and metrology at 13.5 nm has been widely reported and recent research efforts have focused on developing next generation sources for lithography, surface morphology, patterning and microscopy at shorter wavelengths. In this paper, the spectra emitted from LPPs of the 2nd transition row elements from yttrium (Z = 39) to palladium (Z = 46), with the exception of zirconium (Z = 40) and technetium (Z = 43), produced by two Nd:YAG lasers which delivered up to 600 mJ in 7 ns and 230 mJ in 170 ps, respectively, are reported. Intense emission was observed in the 2-8 nm spectral region resulting from unresolved transition arrays (UTAs) due to 3d-4p, 3d-4f and 3p-3d transitions. These transitions in a number of ion stages of yttrium, niobium, ruthenium and rhodium were identified by comparison with results from Cowan code calculations and previous studies. The theoretical data were parameterized using the UTA formalism and the mean wavelength and widths were calculated and compared with experimental results.

    2006-01-01

    Let be a map of a compact, connected Riemannian manifold, with or without boundary. For sufficiently small, we introduce an -Nielsen number that is a lower bound for the number of fixed points of all self-maps of that are -homotopic to . We prove that there is always a map that is -homotopic to such that has exactly fixed points. We describe procedures for calculating for maps of -manifolds.

  10. The quasi-fixed MSSM

    The infra-red fixed points are determined for the parameters of the MSSM. They dominate the renormalisation group running when the top-Yukawa is in the quasi-fixed point regime (i.e. large at the GUT scale). We examine this behaviour analytically, by solving the full set of one-loop renormalisation group equations in the approximation that the electroweak contributions are negligible, and also numerically.

As a generalization of contraction maps, the concept of quasi contraction multivalued maps on a topological vector space will be defined. Further, it is shown that a quasi contraction and closed multivalued map on a topological vector space has a unique fixed point if it is bounded value.

  13. Quantum Gravity (2nd edn)

    There has been a flurry of books on quantum gravity in the past few years. The first edition of Kiefer's book appeared in 2004, about the same time as Carlo Rovelli's book with the same title. This was soon followed by Thomas Thiemann's 'Modern Canonical Quantum General Relativity'. Although the main focus of each of these books is non-perturbative and non-string approaches to the quantization of general relativity, they are quite orthogonal in temperament, style, subject matter and mathematical detail. Rovelli and Thiemann focus primarily on loop quantum gravity (LQG), whereas Kiefer attempts a broader introduction and review of the subject that includes chapters on string theory and decoherence. Kiefer's second edition attempts an even wider and somewhat ambitious sweep with 'new sections on asymptotic safety, dynamical triangulation, primordial black holes, the information-loss problem, loop quantum cosmology, and other topics'. The presentation of these current topics is necessarily brief given the size of the book, but effective in encapsulating the main ideas in some cases. For instance the few pages devoted to loop quantum cosmology describe how the mini-superspace reduction of the quantum Hamiltonian constraint of LQG becomes a difference equation, whereas the discussion of 'dynamical triangulations', an approach to defining a discretized Lorentzian path integral for quantum gravity, is less detailed. The first few chapters of the book provide, in a roughly historical sequence, the covariant and canonical metric variable approach to the subject developed in the 1960s and 70s. The problem(s) of time in quantum gravity are nicely summarized in the chapter on quantum geometrodynamics, followed by a detailed and effective introduction of the WKB approach and the semi-classical approximation. These topics form the traditional core of the subject. The next three chapters cover LQG, quantization of black holes, and quantum cosmology. Of these the chapter on LQG is the shortest at fourteen pages-a reflection perhaps of the fact that there are two books and a few long reviews of the subject available written by the main protagonists in the field. The chapters on black holes and cosmology provide a more or less standard introduction to black hole thermodynamics, Hawking and Unruh radiation, quantization of the Schwarzschild metric and mini-superspace collapse models, and the DeWitt, Hartle-Hawking and Vilenkin wavefunctions. The chapter on string theory is an essay-like overview of its quantum gravitational aspects. It provides a nice introduction to selected ideas and a guide to the literature. Here a prescient student may be left wondering why there is no quantum cosmology in string theory, perhaps a deliberate omission to avoid the 'landscape' and its fauna. In summary, I think this book succeeds in its purpose of providing a broad introduction to quantum gravity, and nicely complements some of the other books on the subject. (book review)

  14. Experimental Stochatics (2nd edition)

    Otto Moeschlin and his co-authors have written a book about simulation of stochastic systems. The book comes with a CD-ROM that contains the experiments discussed in the book, and the text from the book is repeated on the CD-ROM. According to the authors, the aim of the book is to give a quick introduction to stochastic simulation for 'all persons interested in experimental stochastics'. To please this diverse audience, the authors offer a book that has four parts. Part 1, called 'Artificial Randomness', is the longest of the four parts. It gives an overview of the generation, testing and basic usage of pseudo random numbers in simulation. Although algorithms for generating sequences of random numbers are fundamental to simulation, it is a slightly unusual choice to give it such weight in comparison to other algorithmic topics. The remaining three parts consist of simulation case studies. Part 2, 'Stochastic Models', treats four problems - Buffon's needle, a queuing system, and two problems related to the kinetic theory of gases. Part 3 is called 'Stochastic Processes' and discusses the simulation of discrete time Markov chains, birth-death processes, Brownian motion and diffusions. The last section of Part 3 is about simulation as a tool to understand the traffic flow in a system controlled by stoplights, an area of research for the authors. Part 4 is called 'Evaluation of Statistical Procedures'. This section contains examples where simulation is used to test the performance of statistical methods. It covers four examples: the Neymann-Pearson lemma, the Wald sequential test, Bayesian point estimation and Hartigan procedures. The CD-ROM contains an easy-to-install software package that runs under Microsoft Windows. The software contains the text and simulations from the book. What I found most enjoyable about this book is the number of topics covered in the case studies. The highly individual selection of applications, which may serve as a source of inspiration for teachers of computational stochastic methods, is the main contribution of this electronic monograph. However, both the book and software suffer from several severe problems. Firstly, I feel that the structure of the text is weak. Probably this is partly the result of the text from the CD-ROM being put into a book format, but the short paragraphs and poorly structured sentences destroy the reading experience. Secondly, although the software is functional, I believe that, like me, many users will be disappointed by the quality of the user interface and the visualizations. The opportunities to interact with the simulations are limited. Thirdly, the presentation is slightly old fashioned and lacking in pedagogical structure. For example, flow charts and Pascal programs are used to present algorithms. To conclude, I am surprised that this electronic monograph warranted a second edition in this form. Teachers may find the examples useful as a starting point, but students and researchers are advised to look elsewhere. (book review)

  16. Funding human services: fixed utility versus fixed budget.

    McCready, D J; Rahn, S L

    1986-01-01

    It is argued in this paper that government allocations for human services based on inputs rather than outcomes, reduce efficiency in social and health service provision. An alternative system of budgeting or contracting on the basis of cost-per-closed case and case outcome is discussed. An interdependency between fixed budget and fixed utility models of allocation is affirmed. The locus of decision-making for operationalizing this interdependency is seen as the program and budget review panel to which operating agencies and government departments must submit financial and program accounting information from year to year. In isolation, the fixed budget approach degenerates into routine allocation or contract renewal with a focus on such input and output variables as volume of service and unit cost, and the fixed utility approach, into political stalemate. Simulated examples are given to demonstrate how allocation on the basis of inputs and outputs alone provides an incentive to inefficiency, and a fixed utility orientation to efficiency.

  17. The Ukrainian community of Western Siberia: specific features of formation and development in the 2nd half of the 19th – early 20th century

    Vladimir N. Shaidurov

    2016-03-01

    Full Text Available The agrarian crisis in the European part of the Russian Empire in the middle of the 20th century seriously impeded agricultural progress. Agrarian overpopulation and peasants deprived of land in the course of the peasant reform of 1861 further aggravated the negative situation in the governorates of Central Russia, Belarus, and left-bank Ukraine. These factors provided fertile soil for migratory sentiments among peasants. It was resettlement in vacant lands in the Asiatic Russia and North Caucasus, which allowed most of them to preserve their homesteads. In the 2nd half of the 19th – early 20th century, Ukrainian peasants were actively engaged in the migration movement which was supported by the state. One of the main placement areas became Western Siberia where a large Ukrainian peasant community was formed. The history of research on the Ukrainian community in Western Siberia is fragmentary, as many aspects remain unstudied. Hence, the article focuses on the following questions: causes of the Ukrainian migration to the border lands of the Russian Empire; stages in the migration; main areas where Ukrainians resided in Siberia; population dynamics of the Ukrainian community; adaptation patterns specific for Ukrainian migrants in their new places of residence; their role in the economic life of Siberia in the early 20th century. This article utilizes primary data from the All-Russian Agricultural and Land Census of 1917, which have been introduced for scientific use for the first time. As the methodological basis, the study draws on the system approach combining regional, neo-imperial and comparative principles.

  19. Bone fractures as indicators of intentional violence in the eastern Adriatic from the antique to the late medieval period (2nd-16th century AD).

    Slaus, Mario; Novak, Mario; Bedić, Zeljka; Strinović, Davor

    2012-09-01

    To test the historically documented hypothesis of a general increase in deliberate violence in the eastern Adriatic from the antique (AN; 2nd-6th c.) through the early medieval (EM; 7th-11th c.) to the late-medieval period (LM; 12th-16th c.), an analysis of the frequency and patterning of bone trauma was conducted in three skeletal series from these time periods. A total of 1,125 adult skeletons-346 from the AN, 313 from the EM, and 466 from the LM series-were analyzed. To differentiate between intentional violence and accidental injuries, data for trauma frequencies were collected for the complete skeleton, individual long bones, and the craniofacial region as well as by type of injury (perimortem vs. antemortem). The results of our analyses show a significant temporal increase in total fracture frequencies when calculated by skeleton as well as of individuals exhibiting one skeletal indicator of deliberate violence (sharp force lesions, craniofacial injuries, "parry" fractures, or perimortem trauma). No significant temporal increases were, however, noted in the frequencies of craniofacial trauma, "parry" fractures, perimortem injuries, or of individuals exhibiting multiple skeletal indicators of intentional violence. Cumulatively, these data suggest that the temporal increase in total fracture frequencies recorded in the eastern Adriatic was caused by a combination of factors that included not only an increase of intentional violence but also a significant change in lifestyle that accompanied the transition from a relatively affluent AN urban lifestyle to a more primitive rural medieval way of life.

  3. Evidence of the Big Fix

    Hamada, Yuta; Kawana, Kiyoharu

    2014-01-01

    We give an evidence of the Big Fix. The theory of wormholes and multiverse suggests that the parameters of the Standard Model are fixed in such a way that the total entropy at the late stage of the universe is maximized, which we call the maximum entropy principle. In this paper, we discuss how it can be confirmed by the experimental data, and we show that it is indeed true for the Higgs vacuum expectation value $v_{h}$. We assume that the baryon number is produced by the sphaleron process, and that the current quark masses, the gauge couplings and the Higgs self coupling are fixed when we vary $v_{h}$. It turns out that the existence of the atomic nuclei plays a crucial role to maximize the entropy. This is reminiscent of the anthropic principle, however it is required by the fundamental low in our case.

  4. Fixed-point signal processing

    Padgett, Wayne T

    2009-01-01

    This book is intended to fill the gap between the ""ideal precision"" digital signal processing (DSP) that is widely taught, and the limited precision implementation skills that are commonly required in fixed-point processors and field programmable gate arrays (FPGAs). These skills are often neglected at the university level, particularly for undergraduates. We have attempted to create a resource both for a DSP elective course and for the practicing engineer with a need to understand fixed-point implementation. Although we assume a background in DSP, Chapter 2 contains a review of basic theory

    2013-01-01

    The study of theory of fuzzy sets was initiated by Zadeh in 1965. Since then many authors have extended and developed the theory of fuzzy sets in the fields of topology and analysis. The notion of fuzzy metric spaces has very important applications in quantum particle physics. As a result many authors have extended the Banach’sContraction Principle to fuzzy metric spaces. Fixed point and common fixed point properties for mappings defined on fuzzy metric spaces have been studied by many author...

  13. Can mushrooms fix atmospheric nitrogen?

    H S Jayasinghearachchi; Gamini Seneviratne

    2004-09-01

    It is generally reported that fungi like Pleurotus spp. can fix nitrogen (N2). The way they do it is still not clear. The present study hypothesized that only associations of fungi and diazotrophs can fix N2. This was tested in vitro. Pleurotus ostreatus was inoculated with a bradyrhizobial strain nodulating soybean and P. ostreatus with no inoculation was maintained as a control. At maximum mycelial colonization by the bradyrhizobial strain and biofilm formation, the cultures were subjected to acetylene reduction assay (ARA). Another set of the cultures was evaluated for growth and nitrogen accumulation. Nitrogenase activity was present in the biofilm, but not when the fungus or the bradyrhizobial strain was alone. A significant reduction in mycelial dry weight and a significant increase in nitrogen concentration were observed in the inoculated cultures compared to the controls. The mycelial weight reduction could be attributed to C transfer from the fungus to the bradyrhizobial strain, because of high C cost of biological N2 fixation. This needs further investigations using 14C isotopic tracers. It is clear from the present study that mushrooms alone cannot fix atmospheric N2. But when they are in association with diazotrophs, nitrogenase activity is detected because of the diazotrophic N2 fixation. It is not the fungus that fixes N2 as reported earlier. Effective N2 fixing systems, such as the present one, may be used to increase protein content of mushrooms. Our study has implications for future identification of as yet unidentified N2 systems occurring in the environment.

  16. Design and DSP Implementation of Fixed-Point Systems

    Coors Martin

    2002-01-01

    Full Text Available This article is an introduction to the FRIDGE design environment which supports the design and DSP implementation of fixed-point digital signal processing systems. We present the tool-supported transformation of signal processing algorithms coded in floating-point ANSI C to a fixed-point representation in SystemC. We introduce the novel approach to control and data flow analysis, which is necessary for the transformation. The design environment enables fast bit-true simulation by mapping the fixed-point algorithm to integral data types of the host machine. A speedup by a factor of 20 to 400 can be achieved compared to C++-library-based bit-true simulation. FRIDGE also provides a direct link to DSP implementation by processor specific C code generation and advanced code optimization.

  17. Quantification of left and right ventricular function and myocardial mass: Comparison of low-radiation dose 2nd generation dual-source CT and cardiac MRI

    Objective: To prospectively evaluate the accuracy of left and right ventricular function and myocardial mass measurements based on a dual-step, low radiation dose protocol with prospectively ECG-triggered 2nd generation dual-source CT (DSCT), using cardiac MRI (cMRI) as the reference standard. Materials and methods: Twenty patients underwent 1.5 T cMRI and prospectively ECG-triggered dual-step pulsing cardiac DSCT. This image acquisition mode performs low-radiation (20% tube current) imaging over the majority of the cardiac cycle and applies full radiation only during a single adjustable phase. Full-radiation-phase images were used to assess cardiac morphology, while low-radiation-phase images were used to measure left and right ventricular function and mass. Quantitative CT measurements based on contiguous multiphase short-axis reconstructions from the axial CT data were compared with short-axis SSFP cardiac cine MRI. Contours were manually traced around the ventricular borders for calculation of left and right ventricular end-diastolic volume, end-systolic volume, stroke volume, ejection fraction and myocardial mass for both modalities. Statistical methods included independent t-tests, the Mann–Whitney U test, Pearson correlation statistics, and Bland–Altman analysis. Results: All CT measurements of left and right ventricular function and mass correlated well with those from cMRI: for left/right end-diastolic volume r = 0.885/0.801, left/right end-systolic volume r = 0.947/0.879, left/right stroke volume r = 0.620/0.697, left/right ejection fraction r = 0.869/0.751, and left/right myocardial mass r = 0.959/0.702. Mean radiation dose was 6.2 ± 1.8 mSv. Conclusions: Prospectively ECG-triggered, dual-step pulsing cardiac DSCT accurately quantifies left and right ventricular function and myocardial mass in comparison with cMRI with substantially lower radiation exposure than reported for traditional retrospective ECG-gating.

  18. Genetic and structural analysis of the Rhizobium meliloti fixA, fixB, fixC, and fixX genes.

    The fixA, fixB, fixC, and fixX genes of Rhizobium meliloti 1021 constitute an operon and are required for nitrogen fixation in alfalfa nodules. DNA homologous to the R. meliloti fixABC genes is present in all other Rhizobium and Bradyrhizobium species examined, but fixABC-homologous sequences were found in only one free-living diazotroph, Azotobacter vinelandii. To determine whether the fixABCX genes share sequence homology with any of the 17 Klebsiella pneumoniae nif genes, we determined the...

  19. Second-order adjoint sensitivity analysis methodology (2nd-ASAM) for computing exactly and efficiently first- and second-order sensitivities in large-scale linear systems: II. Illustrative application to a paradigm particle diffusion problem

    Cacuci, Dan G.

    2015-03-01

    This work presents an illustrative application of the second-order adjoint sensitivity analysis methodology (2nd-ASAM) to a paradigm neutron diffusion problem, which is sufficiently simple to admit an exact solution, thereby making transparent the underlying mathematical derivations. The general theory underlying 2nd-ASAM indicates that, for a physical system comprising Nα parameters, the computation of all of the first- and second-order response sensitivities requires (per response) at most (2Nα + 1) "large-scale" computations using the first-level and, respectively, second-level adjoint sensitivity systems (1st-LASS and 2nd-LASS). Very importantly, however, the illustrative application presented in this work shows that the actual number of adjoint computations needed for computing all of the first- and second-order response sensitivities may be significantly less than (2Nα + 1) per response. For this illustrative problem, four "large-scale" adjoint computations sufficed for the complete and exact computations of all 4 first- and 10 distinct second-order derivatives. Furthermore, the construction and solution of the 2nd-LASS requires very little additional effort beyond the construction of the adjoint sensitivity system needed for computing the first-order sensitivities. Very significantly, only the sources on the right-sides of the diffusion (differential) operator needed to be modified; the left-side of the differential equations (and hence the "solver" in large-scale practical applications) remained unchanged. All of the first-order relative response sensitivities to the model parameters have significantly large values, of order unity. Also importantly, most of the second-order relative sensitivities are just as large, and some even up to twice as large as the first-order sensitivities. In the illustrative example presented in this work, the second-order sensitivities contribute little to the response variances and covariances. However, they have the

    We present a new parametrization of a SU(3) fixed point (FP) gauge action using smeared ('fat') gauge links. We report on the scaling behaviour of the FP action on coarse lattices by means of the static quark-antiquark potential, the hadronic scale r0, the string tension σ and the critical temperature Tc of the deconfining phase transition. In addition, we investigate the low lying glueball masses where we observe no scaling violations within the statistical errors

  3. Fixed target flammable gas upgrades

    In the past, fixed target flammable gas systems were not supported in an organized fashion. The Research Division, Mechanical Support Department began to support these gas systems for the 1995 run. This technical memo describes the new approach being used to supply chamber gasses to fixed target experiments at Fermilab. It describes the engineering design features, system safety, system documentation and performance results. Gas mixtures provide the medium for electron detection in proportional and drift chambers. Usually a mixture of a noble gas and a polyatomic quenching gas is used. Sometimes a small amount of electronegative gas is added as well. The mixture required is a function of the specific chamber design, including working voltage, gain requirements, high rate capability, aging and others. For the 1995 fixed target run all the experiments requested once through gas systems. We obtained a summary of problems from the 1990 fixed target run and made a summary of the operations logbook entries from the 1991 run. These summaries primarily include problems involving flammable gas alarms, but also include incidents where Operations was involved or informed. Usually contamination issues were dealt with by the experimenters. The summaries are attached. We discussed past operational issues with the experimenters involved. There were numerous incidents of drift chamber failure where contaminated gas was suspect. However analyses of the gas at the time usually did not show any particular problems. This could have been because the analysis did not look for the troublesome component, the contaminant was concentrated in the gas over the liquid and vented before the sample was taken, or that contaminants were drawn into the chambers directly through leaks or sub-atmospheric pressures. After some study we were unable to determine specific causes of past contamination problems, although in argon-ethane systems the problems were due to the ethane only

  4. Radioiodine treatment for complicated hyperthyroidism using a fixed dose regime

    patients remained hyperthyroid 6 months after treatment. Thus, 11 (11.83%) patients remaining hyperthyroid 6 months following I-131 treatment and they were treated with a 2nd dose of 15 mCi I-131. No patient required more than two doses of I-131 in this study. In conclusion an initial dose 15 mCi of I-131 is a simple, safe and effective means for the treatment of patient with complicated hyperthyroidism. (author)

  5. A fixed-point farrago

    Shapiro, Joel H

    2016-01-01

    This text provides an introduction to some of the best-known fixed-point theorems, with an emphasis on their interactions with topics in analysis. The level of exposition increases gradually throughout the book, building from a basic requirement of undergraduate proficiency to graduate-level sophistication. Appendices provide an introduction to (or refresher on) some of the prerequisite material and exercises are integrated into the text, contributing to the volume’s ability to be used as a self-contained text. Readers will find the presentation especially useful for independent study or as a supplement to a graduate course in fixed-point theory. The material is split into four parts: the first introduces the Banach Contraction-Mapping Principle and the Brouwer Fixed-Point Theorem, along with a selection of interesting applications; the second focuses on Brouwer’s theorem and its application to John Nash’s work; the third applies Brouwer’s theorem to spaces of infinite dimension; and the fourth rests ...

  7. BRST gauge fixing and regularization

    In the presence of consistent regulators, the standard procedure of BRST gauge fixing (or moving from one gauge to another) can require non-trivial modifications. These modifications occur at the quantum level, and gauges exist which are only well-defined when quantum mechanical modifications are correctly taken into account. We illustrate how this phenomenon manifests itself in the solvable case of two-dimensional bosonization in the path-integral formalism. As a by-product, we show how to derive smooth bosonization in Batalin-Vilkovisky Lagrangian BRST quantization. (orig.)

  9. Fixed-Target Electron Accelerators

    A tremendous amount of scientific insight has been garnered over the past half-century by using particle accelerators to study physical systems of sub-atomic dimensions. These giant instruments begin with particles at rest, then greatly increase their energy of motion, forming a narrow trajectory or beam of particles. In fixed-target accelerators, the particle beam impacts upon a stationary sample or target which contains or produces the sub-atomic system being studied. This is in distinction to colliders, where two beams are produced and are steered into each other so that their constituent particles can collide. The acceleration process always relies on the particle being accelerated having an electric charge; however, both the details of producing the beam and the classes of scientific investigations possible vary widely with the specific type of particle being accelerated. This article discusses fixed-target accelerators which produce beams of electrons, the lightest charged particle. As detailed in the report, the beam energy has a close connection with the size of the physical system studied. Here a useful unit of energy is a GeV, i.e., a giga electron-volt. (ne GeV, the energy an electron would have if accelerated through a billion volts, is equal to 1.6 x 10-10 joules.) To study systems on a distance scale much smaller than an atomic nucleus requires beam energies ranging from a few GeV up to hundreds of GeV and more

    Ponto, Kate

    2008-01-01

    The Lefschetz fixed point theorem follows easily from the identification of the Lefschetz number with the fixed point index. This identification is a consequence of the functoriality of the trace in symmetric monoidal categories. There are refinements of the Lefschetz number and the fixed point index that give a converse to the Lefschetz fixed point theorem. An important part of this theorem is the identification of these different invariants. We define a generalization of the trace in symmet...

    The fixed point actions for Wilson and staggered lattice fermions are determined by iterating renormalization group transformations. In both cases a line of fixed points is found. Some points have very local fixed point actions. They can be used to construct perfect lattice actions for asymptotically free fermionic theories like QCD or the Gross-Neveu model. The local fixed point actions for Wilson fermions break chiral symmetry, while in the staggered case the remnant $U(1)_e \\otimes U(1)_o$...

  12. Phase equilibria and crystal chemistry of the CaO–1/2 Nd2O3–CoOz system at 885 °C in air

    The phase diagram of the CaO–1/2 Nd2O3–CoOz system at 885 °C in air has been determined. The system consists of two calcium cobaltate compounds that have promising thermoelectric properties, namely, the 2D thermoelectric oxide solid solution, (Ca3−xNdx)Co4O9−z (0≤x≤0.5), which has a misfit layered structure, and Ca3Co2O6 which consists of 1D chains of alternating CoO6 trigonal prisms and CoO6 octahedra. Ca3Co2O6 was found to be a point compound without the substitution of Nd on the Ca site. The reported Nd2CoO4 phase was not observed at 885 °C. A ternary (Ca1−xNd1+x)CoO4−z (x=0) phase, or (CaNdCo)O4−z, was found to be stable at this temperature. A solid solution region of distorted perovskite (Nd1−xCax)CoO3−z (0≤x≤0.25, space group Pnma) was established. In the peripheral binary systems, while a solid solution region was identified for (Nd1−xCax)2O3−z (0≤x≤0.2), Nd was not found to substitute in the Ca site of CaO. Six solid solution tie-line regions and six three-phase regions were determined in the CaO–Nd2O3–CoOz system in air. - Graphical abstract: Phase diagram of the 1/2 Nd2O3–CaO–CoOx system at 885 °C, showing the limits of various solid solutions, and the tie-line relationships of various phases. - Highlights: • Phase diagram of the CaO–1/2 Nd2O3–CoOz system constructed. • System consists of thermoelectric oxide (Ca3−xNdx)Co4O9−z (0≤x≤0.5). • Structures of (Nd1−xCax)CoO3−z and (CaNdCo)O4−z determined

    Anon.

    2009-03-15

    Gasification is a flexible, reliable, and clean energy technology that can turn a variety of low-value feedstocks into high-value products, help reduce our dependence on foreign oil and natural gas, and can provide a clean alternative source of baseload electricity, fertilizers, fuels, and chemicals. According to the Gasification Technologies Council (www.gasification.org) today there are more than 420 gasifiers currently in use in some 140 facilities worldwide. By 2015, worldwide gasification capacity is projected to grow 70%, with 80% of the growth occurring in Asia. The prime movers behind this expected growth are the chemical, fertilizer, and coal-to-liquids industries in China, oil sands in Canada, polygeneration (hydrogen and power or chemicals) and substitute natural gas in the United States, and refining in Europe. Looking far into the future gasification can be a link technology to a hydrogen economy as it produces the hydrogen that will be needed for fuel cells. The heart of a gasification plant is the gasifier. There are several basic designs, distinguished by the use of wet or dry feed, the use of air or oxygen, the reactor's flow direction (up-flow, downflow, or circulating), and the gas cooling process. Hereunder, in addition to Abraham who gives examples of a fluidized and an entrained flow gasifier, the Lurgi fixed bed gasifier as well as the two entrained flow gasifiers from Shell and GE as examples for worldwide utilized gasifiers are shortly described.

  15. Iterative approximation of fixed points

    Berinde, Vasile

    2007-01-01

    The aim of this monograph is to give a unified introductory treatment of the most important iterative methods for constructing fixed points of nonlinear contractive type mappings. It summarizes the most significant contributions in the area by presenting, for each iterative method considered (Picard iteration, Krasnoselskij iteration, Mann iteration, Ishikawa iteration etc.), some of the most relevant, interesting, representative and actual convergence theorems. Applications to the solution of nonlinear operator equations as well as the appropriate error analysis of the main iterative methods, are also presented. Due to the explosive number of research papers on the topic (in the last 15 years only, more than one thousand articles related to the subject were published), it was felt that such a monograph was imperatively necessary. The volume is useful for authors, editors, and reviewers. It introduces concrete criteria for evaluating and judging the plethora of published papers.

  16. Link mining models, algorithms, and applications

    Yu, Philip S; Faloutsos, Christos

    2010-01-01

    This book presents in-depth surveys and systematic discussions on models, algorithms and applications for link mining. Link mining is an important field of data mining. Traditional data mining focuses on 'flat' data in which each data object is represented as a fixed-length attribute vector. However, many real-world data sets are much richer in structure, involving objects of multiple types that are related to each other. Hence, recently link mining has become an emerging field of data mining, which has a high impact in various important applications such as text mining, social network analysi

  20. Fixed bed nuclear reactor concept

    Full text: The fixed bed nuclear reactor (FBNR) is essentially a pressurized light water reactor (PWR) having spherical fuel elements constituting a suspended reactor core at its lowest bed porosity. The core is movable thus under any adverse condition, the fuel elements can leave the reactor core naturally through the force of gravity and fall into the passively cooled fuel chamber or leave the reactor all together entering the spent fuel pool. It is a small and modular reactor being simple in design. Its spent fuel is in such a convenient form and size that may be utilized directly as the source for irradiation and applications in agriculture and industry. This feature results in a positive impact on waste management and environmental protection. The principle features of the proposed reactor are that the concept is polyvalent, simple in design, may operate either as fixed or fluidized bed, have the core suspended contributing to inherent safety, passive cooling features of the reactor. The reactor is modular and has integrated primary system utilizing either water, supercritical steam or helium gas as its coolant. Some of the advantages of the proposed reactor are being modular, low environmental impact, exclusion of severe accidents, short construction period, flexible adaptation to demand, excellent load following characteristics, and competitive economics. The characteristics of the Fluidized Bed Nuclear Reactor (FBNR) concept may be analyzed under the light of the requirements set for the IV generation nuclear reactors. It is shown that FBNR meet the goals of (1) Providing sustainable energy generation that meets clean air objectives and promotes long-term availability of systems and effective fuel utilization for worldwide energy production, (2) Minimize and manage their nuclear waste and notably reduce the long term stewardship burden in the future, thereby improving protection for the public health and the environment, (3) Excel in safety and reliability

  1. Fixed drug eruptions with modafinil

    Loknath Ghoshal

    2015-01-01

    Full Text Available Modafinil is a psychostimulant drug, which has been approved by the US Food and Drug Administration for the treatment of narcolepsy associated excessive daytime sleepiness, sleep disorder related to shift work, and obstructive sleep apnea syndrome. However, presently it is being used as a lifestyle medicine; in India, it has been misused as an "over the counter" drug. Modafinil is known to have several cutaneous side effects. Fixed drug eruption (FDE is a distinctive drug induced reaction pattern characterized by recurrence of eruption at the same site of the skin or mucous membrane with repeated systemic administration. Only two case reports exist in the literature describing modafinil induced FDE until date. Here, we report two similar cases. The increasing use of this class of drug amongst the medical personnel might be posing a threat to the proper use and encouraging subsequent abuse. There might be a considerable population using these drugs unaware of the possible adverse effects. Authorities should be more alert regarding the sale and distribution of such medicines.

  2. Can we fix nuclear energy

    Dr. Weinberg discusses some of the history of various aspects of the nuclear industry in light of the accident at Three Mile Island. The siting of commercial nuclear power plants near population centers is a result of opening up nuclear operations at the private sector. Early reactors established as a part of the Manhattan Project were all remote from unknowledgeable populations. When the utilities began to construct nuclear plants, their siting tended to conform to the practices already established for generation plants. With the nearness of nuclear power plants to people, and with media coverage of accidents so widespread, the public perception of risk associated with nuclear energy deserves attention. The primary issue concerning nuclear power plants is, according to Dr. Weinberg, the 15 billion curies in an operating reactor and the possibility of their release. He identifies six characteristics necessary for an acceptable nuclear energy system: technical fixes; physical isolation; separation of generation and distribution; professionalization of the nuclear cadre; heightened security; and, perhaps most difficult, public education about the hazards of radiation. The major alternatives to fission - geothermal, fusion, fossil, and the various forms of solar energy - are discussed briefly

  3. Fixed type incore instrumentation system

    The present invention concerns a fixed type incore instrumentation system for use in BWR type reactor. A sensitivity ratio of an axially disposed gamma thermometer detection portions is determined based on output signals when the heater incorporated in the gamma thermometer generates heat or when it does not generate heat, and the ratio of gamma heat generation amount of the detection portions is determined based on the above-mentioned sensitivity ratio. The absolute value of the gamma heat generation amount is determine so as to agree with radial components of the power distribution of the reactor core obtained using a physical model of the reactor core, and also determined so as to correspond to the output distribution just after disposing neutron detectors. It is monitored whether the change of the sensitivity ratio of the gamma thermometer detection portions is uniform for detection portions in axial direction or it is increased only in a certain detection portion to judge failure of incorporated heater or that of sensors. The detection portion as a standard of the sensitivity ratio is adapted to have the maximum output signal in the axial direction so as to minimize the error of output signals. (N.H.)

    2014-01-01

    The fixed point method has been applied for the first time, in proving the stability results for functional equations, by Baker (1991); he used a variant of Banach's fixed point theorem to obtain the stability of a functional equation in a single variable. However, most authors follow the approaches involving a theorem of Diaz and Margolis. The main aim of this survey is to present applications of different fixed point theorems to the theory of stability of functional equations, motivated by ...

  5. Fixed-fee Pricing and Entry

    Ryoko Oki

    2015-01-01

    This study considers the anti-competitive effect of fixed-fee pricing, such as the one seen in a recent antitrust case in Japan. We show that fixed-fee pricing has stronger exclusionary effect than the per-use pricing's exclusionary effect. However, the restriction on usage of fixed-fee pricing may have a welfare-decreasing effect, although the restriction promotes entry.

  6. A fixed-point action for the lattice Schwinger model

    We determine non-perturbatively a fixed-point (FP) action for fermions in the two-dimensional U(1) gauge (Schwinger) model. Our parameterization for the fermionic action has terms within a 7 x 7 square on the lattice using compact link variables. With the Wilson fermion action as starting point we determine the FP-action by iterating a block spin transformation (BST) with a blocking factor of 2 in the background of non-compact gauge field configurations sampled according to the (perfect) Gaussian measure. We simulate the model at various values of β and find excellent improvement for the studied observables. (orig.)

  7. Fixed-film processes. Part 1

    Recently, full scale fixed-film or mixed suspended and fixed biomass bioreactors have been applied in many wastewater treatments plants. These process no longer depend on biomass settle ability and can be used to improve the performance of existing plants as required by more stringent discharge permit limits, especially for nutrients and suspended solid. Also, processes may work at high rates making it possible to build small footprint installations. Fixed-film process include trickling filter, moving bed reactors fluidized bed reactors. In the first part, the theoretical base governing fixed-film processes are briefly outlined with some simple examples of calculations underlining the main differences with conventional activated sludge processes

    Kirk WA

    2004-01-01

    Full Text Available We show that if is a bounded open set in a complete space , and if is nonexpansive, then always has a fixed point if there exists such that for all . It is also shown that if is a geodesically bounded closed convex subset of a complete -tree with , and if is a continuous mapping for which for some and all , then has a fixed point. It is also noted that a geodesically bounded complete -tree has the fixed point property for continuous mappings. These latter results are used to obtain variants of the classical fixed edge theorem in graph theory.

  9. Fixed Simplex Property for Retractable Complexes

    Zapart Anna

    2010-01-01

    Full Text Available Abstract Retractable complexes are defined in this paper. It is proved that they have the fixed simplex property for simplicial maps. This implies the theorem of Wallace and the theorem of Rival and Nowakowski for finite trees: every simplicial map transforming vertices of a tree into itself has a fixed vertex or a fixed edge. This also implies the Hell and Nešetřil theorem: any endomorphism of a dismantlable graph fixes some clique. Properties of recursively contractible complexes are examined.

  10. Gauge fixing and the gibbs phenomenon

    We address the question of why global gauge fixing, specifically to the lattice Landau gauge, becomes an extremely lengthy process for large lattices. We construct an artificial 'gauge-fixing' problem which has the essential features encountered in actuality. In the limit in which the size of the system to be gauge fixed becomes infinite, the problem becomes equivalent to finding a series expansion in functions which are related to the Jacobi polynomials. The series converges slowly, as expected. It also converges non-uniformly, which is an observed characteristic of gauge fixing. In the limiting example, the non-uniformity arises through the Gibbs phenomenon

  11. Photogrammetric Measurements in Fixed Wing Uav Imagery

    Gülch, E.

    2012-07-01

    Several flights have been undertaken with PAMS (Photogrammetric Aerial Mapping System) by Germap, Germany, which is briefly introduced. This system is based on the SmartPlane fixed-wing UAV and a CANON IXUS camera system. The plane is equipped with GPS and has an infrared sensor system to estimate attitude values. A software has been developed to link the PAMS output to a standard photogrammetric processing chain built on Trimble INPHO. The linking of the image files and image IDs and the handling of different cases with partly corrupted output have to be solved to generate an INPHO project file. Based on this project file the software packages MATCH-AT, MATCH-T DSM, OrthoMaster and OrthoVista for digital aerial triangulation, DTM/DSM generation and finally digital orthomosaik generation are applied. The focus has been on investigations on how to adapt the "usual" parameters for the digital aerial triangulation and other software to the UAV flight conditions, which are showing high overlaps, large kappa angles and a certain image blur in case of turbulences. It was found, that the selected parameter setup shows a quite stable behaviour and can be applied to other flights. A comparison is made to results from other open source multi-ray matching software to handle the issue of the described flight conditions. Flights over the same area at different times have been compared to each other. The major objective was here to see, on how far differences occur relative to each other, without having access to ground control data, which would have a potential for applications with low requirements on the absolute accuracy. The results show, that there are influences of weather and illumination visible. The "unusual" flight pattern, which shows big time differences for neighbouring strips has an influence on the AT and DTM/DSM generation. The results obtained so far do indicate problems in the stability of the camera calibration. This clearly requests a usage of GCPs for all

  12. Factors influencing bonding fixed restorations

    Medić Vesna

    2008-01-01

    Full Text Available INTRODUCTION Crown displacement often occurs because the features of tooth preparations do not counteract the forces directed against restorations. OBJECTIVE The purpose of this study was to evaluate the effect of preparation designs on retention and resistance of fixed restorations. METHOD The study was performed on 64 differently sized stainless steel dies. Also, caps which were used for evaluated retention were made of stainless steel for each die. After cementing the caps on experimental dies, measuring of necessary tensile forces to separate cemented caps from dies was done. Caps, which were made of a silver-palladium alloy with a slope of 60° to the longitudinal axis formed on the occlusal surface, were used for evaluating resistance. A sudden drop in load pressure recorded by the test machine indicated failure for that cap. RESULTS A significant difference was found between the tensile force required to remove the caps from the dies with different length (p<0.05 and different taper (p<0.01. The greatest retentive strengths (2579.2 N and 2989.8 N were noticed in experimental dies with the greatest length and smallest taper. No statistically significant (p>0.05 differences were found between tensile loads for caps cemented on dies with different diameter. Although there was an apparent slight increase in resistance values for caps on dies with smaller tapers, the increase in resistance for those preparation designs was not statistically significant. There was a significant difference among the resistance values for caps on dies with different length (p<0.01 and diameter (p<0.05. CONCLUSION In the light of the results obtained, it could be reasonably concluded that retention and resistance of the restoration is in inverse proportion to convergence angle of the prepared teeth. But, at a constant convergence angle, retention and resistance increase with rising length and diameter.

    After having recalled the regulatory and technical framework of the calibration of radioprotection measurement instruments, and outlined some technical and operational constraints, the authors report the development of an in situ calibration methodology, i.e. without displacement of the sensor. After the presentation of the calibration chain (from the measurement given by a fixed sensor to the reference value given by a primary standard), they indicate the definition and calculation of the different calibration coefficients allowing the linking up of the different levels, and also the taking of uncertainties into account. They finally report the validation of results

    We summarize recent progress in the understanding of fixed point resolution for conformal field theories. Fixed points in both coset conformal field theories and non-diagonal modular invariants which describe simple current extensions of chiral algebras are investigated. A crucial role is played by the mathematical structures of twining characters and orbit Lie algebras.

    2011-01-01

    Many programmers, when they encounter an error, would like to have the benefit of automatic fix suggestions---as long as they are, most of the time, adequate. Initial research in this direction has generally limited itself to specific areas, such as data structure classes with carefully designed interfaces, and relied on simple approaches. To provide high-quality fix suggestions in a broad area of applicability, the present work relies on the presence of contracts in the code, and on the availability of dynamic analysis to gather evidence on the values taken by expressions derived from the program text. The ideas have been built into the AutoFix-E2 automatic fix generator. Applications of AutoFix-E2 to general-purpose software, such as a library to manipulate documents, show that the approach provides an improvement over previous techniques, in particular purely model-based approaches.

  6. The price of fixed income market volatility

    Mele, Antonio

    2015-01-01

    Fixed income volatility and equity volatility evolve heterogeneously over time, co-moving disproportionately during periods of global imbalances and each reacting to events of different nature. While the methodology for options-based "model-free" pricing of equity volatility has been known for some time, little is known about analogous methodologies for pricing various fixed income volatilities. This book fills this gap and provides a unified evaluation framework of fixed income volatility while dealing with disparate markets such as interest-rate swaps, government bonds, time-deposits and credit. It develops model-free, forward looking indexes of fixed-income volatility that match different quoting conventions across various markets, and uncovers subtle yet important pitfalls arising from naïve superimpositions of the standard equity volatility methodology when pricing various fixed income volatilities. The ultimate goal of the authors´ efforts is to make interest rate volatility standardization a valuable...

  7. An evaluation of knowledge, attitude and practices about prescribing fixed dose combinations among resident doctors

    Nimit Goswami

    2013-01-01

    Full Text Available Background: Fixed Dose Combinations (FDCs improve patient compliance and decrease pill burden. However, irrational prescribing of FDCs is a major health concern. As resident doctors are primarily involved in patient management at tertiary care hospitals, knowledge about prescribing FDCs is of paramount importance. Objective: To evaluate knowledge, attitude and practice, regarding use of FDCs by resident doctors at a tertiary care teaching hospital. Materials and Methods: The study was carried out among resident doctors working at Civil Hospital, Ahmedabad, a tertiary care teaching hospital. One hundred resident doctors from the departments of medicine, obstetrics and gynaecology, surgery, paediatrics, skin and psychiatry, who gave their informed consent, were enrolled. A prevalidated questionnaire regarding knowledge, attitude and prescribing practice of fixed dose combinations was filled up. Data was analyzed with suitable statistical tests. Results: Out of the 100 residents recruited for the study, 34, 33 and 33 residents were selected from the 1 st , 2 nd and 3 rd year respectively. The resident doctors were not aware about all of the advantages and disadvantages of FDCs. On an average, only 31% of the residents (lowest 16% among 1 st year residents had knowledge about the Essential Medicine List (EML. Knowledge about rationality of given FDCs was lacking in 81% of the residents. Only 47% could name a single banned FDC in India. Common sources of information about FDCs were medical representatives, colleagues/peers, the Monthly Index of Medical Specialities (MIMS and Continuous Medical Education (CMEs. A majority of residents (96% agreed that FDCs should be allowed to be marketed. The residents opined that most commonly prescribed FDCs were of antimicrobial drugs, amongst which amoxicillin + clavulanic acid was the most frequent. Conclusion: There is need to improve knowledge about rationality, EML, usage and banned FDCs in post graduate

  8. Connector design in a long-span-fixed dental prosthesis: A three-dimensional finite element analysis

    B H Harshitha Gowda

    2013-01-01

    Full Text Available Objectives: The goal of every prosthetic management is to simulate nature and be in harmony with nature within the physiological limits. The occlusal forces on a fixed dental prosthesis are transmitted to the surrounding structures through pontics, connectors and retainers and more stresses are seen at the connector region. To analyze the stress patterns in cast and soldered connectors between the two pontics and between the retainer and pontic of a four unit fixed dental prosthesis on axial and non axial loading and also to observe and ascertain the need to modify the design of the rigid connectors. Materials and Methods: Subsequently four models each of cast and soldered connectors with cylindrical and triangular design, of dimension 3 × 4 mm and thickness 0.5 mm was designed for the study. The first premolar and second molar were considered as the abutments and 2 nd premolar and 1 st molar as the pontics. The analysis was done using ANSYS version 8.0 software and by placing axial and non-axial load of 40 Newtons each. Results: Von Misses stresses were observed at the connector region between the two pontics, especially in the cervical region. Conclusion: The cylindrical cast connectors showed less stress in comparison to triangular design and the difference in the stress distribution of cast and soldered connectors were marginal. Clinical Significance: The occlusal forces on a fixed dental prosthesis are transmitted to the surrounding structures through pontics, connectors and retainers with maximum stresses concentrated at the connectors. Hence this three-dimensional finite element analysis study investigated stress distribution in a four unit posterior fixed dental prosthesis, having cylindrical and triangular connector designs.

    The singular instanton Floer homology was defined by Kronheimer and Mrowka in connection with their proof that the Khovanov homology is an unknot detector. We study this theory for knots and two-component links using equivariant gauge theory on their double branched covers. We show that the special generator in the singular instanton Floer homology of a knot is graded by the knot signature mod 4, thereby providing a purely topological way of fixing the absolute grading in the theory. Our appr...

    In the first of this two-part series, we find `fixed point factorisation' formulas, towards an understanding of the fusion ring of WZW models. Fixed-point factorisation refers to the simplifications in the data of a CFT involving primary fields fixed by simple-currents. Until now, it has been worked out only for SU(n), where it has developed into a powerful tool for understanding the fusion rings of WZW models of CFT -- e.g. it has lead to closed formulas for NIM-reps and D-brane charges and ...

  11. Magnetic Fixed Points and Emergent Supersymmetry

    Antipin, Oleg; Mojaza, Matin; Pica, Claudio;

    2013-01-01

    We establish in perturbation theory the existence of fixed points along the renormalization group flow for QCD with an adjoint Weyl fermion and scalar matter reminiscent of magnetic duals of QCD [1-3]. We classify the fixed points by analyzing their basin of attraction. We discover that among these...... there are stable supersymmetric ones emerging from a generic nonsupersymmetric renormalization group flow once the mass operators have been properly subtracted away. We therefore conclude that four dimensional supersymmetry can emerge as a fixed point theory from a nonsupersymmetric Lagrangian. Our...

  17. HEALTH INSURANCE: FIXED CONTRIBUTION AND REIMBURSEMENT MAXIMA

    Human Resources Division

    2001-01-01

    Affected by the salary adjustments on 1 January 2001 and the evolution of the staff members and fellows population, the average reference salary, which is used as an index for fixed contributions and reimbursement maxima, has changed significantly. An adjustment of the amounts of the reimbursement maxima and the fixed contributions is therefore necessary, as from 1 January 2001. Reimbursement maxima The revised reimbursement maxima will appear on the leaflet summarizing the benefits for the year 2001, which will be sent out with the forthcoming issue of the CHIS Bull'. This leaflet will also be available from the divisional secretariats and from the UNIQA office at CERN. Fixed contributions The fixed contributions, applicable to some categories of voluntarily insured persons, are set as follows (amounts in CHF for monthly contributions) : voluntarily insured member of the personnel, with normal health insurance cover : 910.- (was 815.- in 2000) voluntarily insured member of the personnel, with reduced heal...

  18. Topological fixed point theory of multivalued mappings

    Górniewicz, Lech

    1999-01-01

    This volume presents a broad introduction to the topological fixed point theory of multivalued (set-valued) mappings, treating both classical concepts as well as modern techniques. A variety of up-to-date results is described within a unified framework. Topics covered include the basic theory of set-valued mappings with both convex and nonconvex values, approximation and homological methods in the fixed point theory together with a thorough discussion of various index theories for mappings with a topologically complex structure of values, applications to many fields of mathematics, mathematical economics and related subjects, and the fixed point approach to the theory of ordinary differential inclusions. The work emphasises the topological aspect of the theory, and gives special attention to the Lefschetz and Nielsen fixed point theory for acyclic valued mappings with diverse compactness assumptions via graph approximation and the homological approach. Audience: This work will be of interest to researchers an...

  1. Fixed-Point Configurable Hardware Components

    Rocher Romuald

    2006-01-01

    Full Text Available To reduce the gap between the VLSI technology capability and the designer productivity, design reuse based on IP (intellectual properties is commonly used. In terms of arithmetic accuracy, the generated architecture can generally only be configured through the input and output word lengths. In this paper, a new kind of method to optimize fixed-point arithmetic IP has been proposed. The architecture cost is minimized under accuracy constraints defined by the user. Our approach allows exploring the fixed-point search space and the algorithm-level search space to select the optimized structure and fixed-point specification. To significantly reduce the optimization and design times, analytical models are used for the fixed-point optimization process.

  2. Fixed-film processes. Part 2

    Recently, full scale fixed-film or mixed suspended have been applied in many wastewater treatments plants. These processes no longer depend on biomass settle ability and can be used to improve the performance of existing plants as required by more stringent discharge permit limits, especially for nutrients suspended solids. Also, processes may work at high rates making is possible to build small footprint installations. Fixed-film processes include trickling filters (and combined suspended and fixed-films processes), rotating biological contactors, biological aerated submerged, filters moving bed reactors, fluidized bed reactors. In the first part, the theoretical based governing fixed-film processes are briefly outlined, with some simple examples of calculations, underlining the main differences with conventional activate sludge processes. In the second part, the most common types of reactors are reviewed

    The development of fixed-dose combinations (FDCs) is becoming increasingly important from a public health perspective. FDCs have advantages when there is an identifiable patient population for whom treatment with a particular combination of actives in a fixed ratio is safe and effective and when all of the actives contribute to the overall therapeutic effect. Such combinations of drugs are particularly useful in the management of chronic diseases. In addition, there can be real clinical benef...

  8. A neutron diffraction study of structural distortion and magnetic ordering in the cation-ordered perovskites Ba{sub 2}Nd{sub 1−x}Y{sub x}MoO{sub 6}

    Collins, Oonagh M. [WestCHEM, Department of Pure and Applied Chemistry, University of Strathclyde, Thomas Graham Building, 295 Cathedral Street, Glasgow, G1 1XL, Scotland (United Kingdom); Cussen, Edmund J., E-mail: Edmund.Cussen@strath.ac.uk [WestCHEM, Department of Pure and Applied Chemistry, University of Strathclyde, Thomas Graham Building, 295 Cathedral Street, Glasgow, G1 1XL, Scotland (United Kingdom)

    2013-04-15

    The cation ordered perovskites Ba{sub 2}Nd{sub 1−x}Y{sub x}MoO{sub 6} (0.04≤x≤0.35) have been synthesised by solid-state techniques under reducing conditions at temperatures up to 1350 °C. Rietveld analyses of X-ray and neutron powder diffraction data show that these compounds adopt a tetragonally distorted perovskite structure. The tetragonal distortion is driven by the bonding requirements of the Ba{sup 2+} cation that occupies the central interstice of the perovskite; this cation would be underbonded if these compounds retained the cubic symmetry exhibited by the prototypical structure. The size and charge difference between the lanthanides and Mo{sup 5+} lead to complete ordering of the cations to give a rock-salt ordering of Nd{sup 3+}/Y{sup 3+}O{sub 6} and MoO{sub 6} octahedra. The I4/m space group symmetry is retained on cooling the x=0.1, 0.2 and 0.35 samples to low temperature ca. 2 K. Ba{sub 2}Nd{sub 0.90}Y{sub 0.10}MoO{sub 6} undergoes a gradual distortion of the MoO{sub 6} units on cooling from room temperature to give two long trans bonds (2.001(2) Å) along the z-direction and four shorter apical bonds (1.9563(13) Å) in the xy-plane. This distortion of the MoO{sub 6} units stabilises the 4d{sup 1} electron in the d{sub xz} and d{sub yz} orbitals whilst the d{sub xy} orbital is increased in energy due to the contraction of the Mo–O bonds in the xy-plane. This bond extension along z is propagated through the structure and gives a negative thermal expansion of −13×10{sup −6} K{sup −1} along c. The overall volumetric thermal expansion is positive due to conventional expansion along the other two crystallographic axes. With increasing Y{sup 3+} content this distortion is reduced in x=0.2 and eliminated in x=0.35 which contains largely regular MoO{sub 6} octahedra. The x=0.1 and x=0.2 show small peaks in the neutron diffraction profile due to long range antiferromagnetic order arising from ordered moments of ca. 2 μ{sub B}. - Graphical

  10. Blade Design Optimisation for Fixed-Pitch Fixed-Speed Wind Turbines

    Lin Wang; Xinzi Tang; Xiongwei Liu

    2012-01-01

    Fixed-pitch fixed-speed (FPFS) wind turbines have some distinct advantages over other topologies for small wind turbines, particularly for low wind speed sites. The blade design of FPFS wind turbines is fundamentally different to fixed-pitch variable-speed wind turbine blade design. Theoretically, it is difficult to obtain a global mathematical solution for the blade design optimisation. Through case studies of a given baseline wind turbine and its blade airfoil, this paper aims to demonstrat...

    2010-03-15

    LINK2009 project was to develop 2nd gen. technologies fuel cell systems for vehicles and 350bar hydrogen refueling stations. Also the LINK2009 project were to ensure a continuously positioning of Denmark and the Scandinavian Region within hydrogen for transport and continue to attract international car manufacturers to conduct demonstration and later market introduction in the region. The LINK2009 project is divided in two phases where this first phase only deals with the development of the 2nd generation technologies, whereas the following phase 2 will include the demonstration hereof as well as additional research activities. This Report describes the results of the phase 1 that was commenced in summer 2008 and ended in late 2009. Phase 1 has resulted in the development of new 2nd generation fuel cell technology for use in a city car and a service vehicle. Stated targets for price and efficiency have been reached and the following demonstration in Phase 2 is to confirm reaching of life time targets. The efficiency of the fuel cell system for the city car has been measured to be 42-48% at a power delivery of respectively 10kW and 2kW, which is significantly above the target of >40%. System simplifications and selection of new components have enabled a 50% reduction in the kW price for the fuel cell system, including 700bar hydrogen storage, now totalling Euro 4.500/kW. This creates sufficient basis for conducting demonstration of the system in vehicles. 9 vehicles are planned to be demonstrated in the following phase 2. Additional 8 vehicles were put in operation in Copenhagen in November 2009. Phase 1 has conducted development of 2nd gen. hydrogen refuelling technology that has resulted in concepts for both 350bar and 700bar refuelling as well as a concept for onsite hydrogen production at refuelling stations. In separate projects the developed 350bar technology has been brought to use in a newly established hydrogen station in Copenhagen, and the hydrogen

  15. The computation of fixed points and applications

    Todd, Michael J

    1976-01-01

    Fixed-point algorithms have diverse applications in economics, optimization, game theory and the numerical solution of boundary-value problems. Since Scarf's pioneering work [56,57] on obtaining approximate fixed points of continuous mappings, a great deal of research has been done in extending the applicability and improving the efficiency of fixed-point methods. Much of this work is available only in research papers, although Scarf's book [58] gives a remarkably clear exposition of the power of fixed-point methods. However, the algorithms described by Scarf have been super~eded by the more sophisticated restart and homotopy techniques of Merrill [~8,~9] and Eaves and Saigal [1~,16]. To understand the more efficient algorithms one must become familiar with the notions of triangulation and simplicial approxi- tion, whereas Scarf stresses the concept of primitive set. These notes are intended to introduce to a wider audience the most recent fixed-point methods and their applications. Our approach is therefore ...

  16. Fixed point theory in metric type spaces

    Agarwal, Ravi P; O’Regan, Donal; Roldán-López-de-Hierro, Antonio Francisco

    2015-01-01

    Written by a team of leading experts in the field, this volume presents a self-contained account of the theory, techniques and results in metric type spaces (in particular in G-metric spaces); that is, the text approaches this important area of fixed point analysis beginning from the basic ideas of metric space topology. The text is structured so that it leads the reader from preliminaries and historical notes on metric spaces (in particular G-metric spaces) and on mappings, to Banach type contraction theorems in metric type spaces, fixed point theory in partially ordered G-metric spaces, fixed point theory for expansive mappings in metric type spaces, generalizations, present results and techniques in a very general abstract setting and framework. Fixed point theory is one of the major research areas in nonlinear analysis. This is partly due to the fact that in many real world problems fixed point theory is the basic mathematical tool used to establish the existence of solutions to problems which arise natur...

  18. Maternal scaffolding behavior: links with parenting style and maternal education.

    Carr, Amanda; Pike, Alison

    2012-03-01

    The purpose of this study was to specify the relationship between positive and harsh parenting and maternal scaffolding behavior. A 2nd aim was to disentangle the effects of maternal education and parenting quality, and a 3rd aim was to test whether parenting quality mediated the association between maternal education and scaffolding practices. We examined associations between positive and harsh parenting practices and contingent and noncontingent tutoring strategies. Ninety-six mother-child dyads (49 boys, 47 girls) from working- and middle-class English families participated. Mothers reported on parenting quality at Time 1 when children were 5 years old and again approximately 5 years later at Time 2. Mother-child pairs were observed working together on a block design task at Time 2, and interactions were coded for contingent (contingent shifting) and noncontingent (fixed failure feedback) dimensions of maternal scaffolding behavior. Positive and harsh parenting accounted for variance in contingent behavior over and above maternal education, whereas only harsh parenting accounted for unique variance in noncontingent scaffolding practices. Our findings provide new evidence for a more differentiated model of the relation between general parenting quality and specific scaffolding behaviors. PMID:22004338

  20. Enhanced temperature-independent magnetoresistance below the metal–insulator transition temperature of epitaxial La0.2Nd0.4Ca0.4MnO3 thin films

    Darshan C Kundaliya; A A Tulapurkar; J John; R Pinto; R G Kulkarni

    2002-05-01

    Epitaxial La0.2Nd0.4Ca0.4MnO3 thin films have been deposited at 800°C on LaAlO3 substrate using pulsed laser deposition technique. The structural and magnetotransport properties of the films have been studied. The sharp peak in the temperature dependence of the resistance corresponding to metal-to-insulator transition (p) has been observed at a temperature of p =82 K, 97 K and 110 K for 0 Oe, 20 kOe and 40 kOe magnetic fields, respectively. The film exhibits a large nearly temperature-independent magnetoresistance around 99% in the temperature regime below p. The zero field-cooled (ZFC) and field-cooled (FC) magnetization data at 50 Oe shows irreversibility between the ZFC and FC close to the ferromagnetic transition temperature c = 250 K. The ZFC temperature data of the film displays ferromagnetic behavior for higher temperature regime c =250 K > T > p = 82 K, and a decrease in magnetization with decreasing temperature up to 5 K below 82 K exhibiting a sort of antiferromagnetic behavior in the low temperature regime ( < 82 K= p = N).

    Full Text Available Dengue Haemorrhagic fever (DHF is one of fearsome diseases in society. Incidence of the disease isincreasing. Dengue fever is caused by dengue virus and transmitted by Aedes aegypti mosquito vector.Various chemical controls have been conducted to prevent the spread of the disease, but active contents ofthe chemical controlling substances are suspected causing many negative effect, in environment, such asvector resistance, death of non target living creatures, and environmental contamination.This researchobjective was to find an alternative solution in order to control the dengue vector by using entomopathogenicfungi as biological control agent. This research was conducted by isolation and identification of fungiinfecting mosquito larvae. Macroscopic observation revealed that one of the nine isolation products wasLagenidium giganteum. The effectiveness test in laboratory showed the zoospore LD50 to Ae.aegypti larvaeof instar 2nd was 2,35 x 106 zoospore/ml, while the LD95 value was 1,35 x 107 zoospore/ml. The oosporeeffectiveness test showed LD50 was 6,7 x 102 oospore/ml and LD95 was 1,94 x 103 oospore/ml. Using LPCBdye and blue tolouidin 2,5%, the infection mechanism of L.giganteum fungi in Ae.aegypti mosquito larvawas detected. The research is concluded that the entomophatogen fungi L. giganteum was very prospectiveto be used as a biological control agent against vector of DHF.

    1997-08-20

    The unique advantage of the pulsed laser deposition is its ability to produce highly oriented stoichiometric films at a low substrate temperature. Ferroelectric PbTiO3 thin films have been formed using 2nd laser assisted laser ablaion technique at low temperature, i.e., 350degC, on Sr7iO3 single-crystal substrates and Pt/MgO electrodes. The second laser irradiation at the substrate surface is quite effective for crystallization of the films at low substrate temperature below 400degC. The suitable energy density (fluence) of the irradiation laser is in the range of 30-100 mJ/cm{sup 2}. X-ray diffraction patterns of PbTiO3 thin films show c-axis orientation, with a rocking angle of 1.0 - 0.5deg. These films exhibit ferroelectric hysteresis loop. The dielectric constant and remanent polalyzation of the PbTiO3 films are in the range of 120-150 and 60-80 {mu}C/cm{sup 2}, respectively. 31 refs., 10 figs., 1 tab.

  3. Fixed target facility at the SSC

    The question of whether a facility for fixed target physics should be provided at the SSC must be answered before the final technical design of the SSC can be completed, particularly if the eventual form of extraction would influence the magnet design. To this end, an enthusiastic group of experimentalists, theoreticians and accelerator specialists have studied this point. The accelerator physics issues were addressed by a group led by E. Colton whose report is contained in these proceedings. The physics addressable by fixed target was considered by many of the Physics area working groups and in particular by the Structure Function Group. This report is the summary of the working group which considered various SSC fixed target experiments and determined which types of beams and detectors would be required. 13 references, 5 figures

  4. A New Clasp to Fix Partial Dentures

    Saakyan М.Yu.

    2012-03-01

    Full Text Available A new clasp to fix small saddle prostheses was designed to improve the quality of prosthetic unilateral free-end saddle restoration. Unlike the known ones, the clasp can be adapted for clinical crowns of any height (particularly useful for low crowns as no standard elements are required to be fixed on prosthesis. Prosthesis retention is independent of the height of coronal part and the evidence of its survey line. Gentle preparation of abutment teeth allows grinding off hard tooth issues minimally. The combination of fixing elements of a single clasp provides sufficient fixation to achieve high masticatory efficiency and prosthesis spatial stabilization but at the same time only partially limits its lability in mastication. The clasp can be used in free-end saddle restoration both in maxilla and mandible, and especially in patients with periodontal diseases complicated by partial tooth loss.

    2013-12-01

    Full Text Available Fixed drug eruption is a common type of drug eruption seen in dermatology OPD’s. Usually it is seen with sulphonamides, salicylates, tetracyclines, oxyphenbutazones, dapsone, barbiturates, phenolphthalein, morphine, codeine, quinine, phenacetin, erythromycin, griseofulvin, mebendazole etc. We hereby report a case of fixed drug eruption due to single dose of oral paracetamol in an otherwise healthy male after one hour of consuming it. A provisional diagnosis of Paracetamol induced fixed drug eruption was made. Paracetamol was stopped and patient advised never to take Paracetamol in future. Patient was managed with prednisolone 10mg /day, cetirizine 10 mg/day, and amoxicillin 500 mg twice a day and mometasone + fusidic acid cream to be applied over the lesions.

  6. Fixed point theory of parametrized equivariant maps

    Ulrich, Hanno

    1988-01-01

    The first part of this research monograph discusses general properties of G-ENRBs - Euclidean Neighbourhood Retracts over B with action of a compact Lie group G - and their relations with fibrations, continuous submersions, and fibre bundles. It thus addresses equivariant point set topology as well as equivariant homotopy theory. Notable tools are vertical Jaworowski criterion and an equivariant transversality theorem. The second part presents equivariant cohomology theory showing that equivariant fixed point theory is isomorphic to equivariant stable cohomotopy theory. A crucial result is the sum decomposition of the equivariant fixed point index which provides an insight into the structure of the theory's coefficient group. Among the consequences of the sum formula are some Borsuk-Ulam theorems as well as some folklore results on compact Lie-groups. The final section investigates the fixed point index in equivariant K-theory. The book is intended to be a thorough and comprehensive presentation of its subjec...

  7. Improving TCP Performance over Wireless Links Using Link-Layer Retransmission and Explicit Loss Notification

    2002-01-01

    In order to support the mobility of computers during communication, the transport control protocol (TCP) con-nections between fixed host and mobile host often traverse wired and wireless networks, and the recovery of the losses dueto wireless transmission error is much different from congestion control. This paper analyzes the interaction between TCPand link layer retransmission scheme when the correlated packet are losses handled, indicates that a higher value of themaximum number of successive link layer timeout retransmissions has an adverse effect on TCP ability to perform conges-tion control rapidly. To achieve a better TCP performance, the paper proposes a strategy combining link-layer selective-re-ject automatic repeat request (ARQ) with explicit loss notification mechanism, which can respond to congestion quicklywhile keeping wireless link more reliable, and make TCP react to the different packet losses more suitably.

    The mobile application (app) has become the main entrance to access the Internet on handheld devices. Unlike the Web where each webpage has a global URL to reach directly, a specific "content page" of an app can be opened only by exploring the app with several operations from the landing page. The interoperability between apps is quite fixed and thus limits the value-added "linked data" between apps.

    2012-01-01

    We consider the problem of packing fixed-length patterns into a permutation, and develop a connection between the number of large patterns and the number of bonds in a permutation. Improving upon a result of Kaplansky and Wolfowitz, we obtain exact values for the expectation and variance for the number of large patterns in a random permutation. Finally, we are able to generalize the idea of bonds to obtain results on fixed-length patterns of any size, and present a construction that maximizes...

  10. Fixing the shadows while moving the gnomon

    2016-01-01

    It is a common practice to fix a vertical gnomon and study the moving shadow cast by it. This shows our local solar time and gives us a hint regarding the season in which we perform the observation. The moving shadow can also tell us our latitude with high precision. In this paper we propose to exchange the roles and while keeping the shadows fixed on the ground we will move the gnomon. This lets us understand in a simple way the relevance of the tropical lines of latitude and the behavior of...

  11. Beauty physics at Fermilab fixed target energies

    Cox, B.

    1988-04-01

    The very high luminosities (>>10/sup 32/cm/sup /minus/2/sec/sup /minus/1/) available in the Fermilab fixed target experimental areas offer immediate opportunities for producing large samples (>10/sup 8/ of B hadrons in individual experiments. The possibilities of accumulating large samples of B decays are limited by experimental techniques and trigger strategies and not by available luminosity. At the present time one experiment, E771, is approved to begin B physics experimentation and several other experimental possibilities are being discussed. Some of the problems and the potential of B experiments at fixed target energies as B factories are discussed.

    Full Text Available Fix & Finish “WHO CAN FIX IT?” is an investigation of the needles left behind by drug users in Copenhagen’s Vesterbro district. Based on the praxiological methods developed by Annemarie Mol as well as processes of objectification as described by Daniel Miller, the used needle appears to be a multiple object that is related to opportunities, fear, good intentions and trash. This article is an invitation to study material culture and material practices as a part of semiotic and discursive analyses in order to sharpen a researcher’s analytical focus while remaining grounded in reality.

  14. On coherent systems with fixed determinant

    Grzegorczyk, I.; Newstead, P. E.

    2013-01-01

    Over the past 20 years, a great deal of work has been done on the moduli spaces of coherent systems on algebraic curves. Until recently, however, there has been very little work on the fixed determinant case, except for the special case of rank 2 and canonical determinant. This situation has changed due to two papers of B. Osserman, who has obtained lower bounds for the dimensions of the fixed determinant moduli spaces in some cases. Our object in this paper is to show that some of Osserman's...

  15. Fixed export cost heterogeneity, trade and welfare

    Jørgensen, Jan Guldager; Schröder, Philipp J.H.

    2008-01-01

    Recent literature on the workhorse model of intra-industry trade has explored heterogeneous cost structures at the firm level. These approaches have proven to add realism and predictive power. This paper presents a new and simple heterogeneous-firms specification. We develop a symmetric two......-country intra-industry trade model where firms are of two different marginal costs types and where fixed export costs are heterogeneous across firms. This model traces many of the stylized facts of international trade. However, we find that with heterogeneous fixed export costs there exists a positive bilateral...

  16. Dynamic link: user's manual

    The purpose of dynamic link facility is to link a load module dynamically only when it is used in execution time. The facility is very useful for development, execution and maintenance of a large scale computer program which is too big to be saved as one load module in main memory, or it is poor economy to save it due to many unused subroutines depending on an input. It is also useful for standardization and common utilization of programs. Standard usage of dynamic link facility of FACOM M-200 computer system, a software tool which analyzes the effect of dynamic link facility and application of dynamic link to nuclear codes are described.

    The overall purpose of this project has been to contribute to this load management by developing a 2{sup nd} generation of alkaline electrolysis system characterized by being compact, reliable, inexpensive and energy efficient. The specific targets for the project have been to: 1) Increase cell efficiency to more than 88% (according to the higher heating value (HHV)) at a current density of 200 mA /cm{sup 2}; 2) Increase operation temperature to more than 100 degree Celsius to make the cooling energy more valuable; 3) Obtain an operation pressure more than 30 bar hereby minimizing the need for further compression of hydrogen for storage; 4) Improve stack architecture decreasing the price of the stack with at least 50%; 5) Develop a modular design making it easy to customize plants in the size from 20 to 200 kW; 6) Demonstrating a 20 kW 2{sup nd} generation stack in H2College at the campus of Arhus University in Herning. The project has included research and development on three different technology tracks of electrodes; an electrochemical plating, an atmospheric plasma spray (APS) and finally a high temperature and pressure (HTP) track with operating temperature around 250 deg. C and pressure around 40 bar. The results show that all three electrode tracks have reached high energy efficiencies. In the electrochemical plating track a stack efficiency of 86.5% at a current density of 177mA/cm{sup 2} and a temperature of 74.4 deg. C has been shown. The APS track showed cell efficiencies of 97%, however, coatings for the anode side still need to be developed. The HTP cell has reached 100 % electric efficiency operating at 1.5 V (the thermoneutral voltage) with a current density of 1. 1 A/cm{sup 2}. This track only tested small cells in an externally heated laboratory set-up, and thus the thermal loss to surroundings cannot be given. The goal set for the 2{sup nd} generation electrolyser system, has been to generate 30 bar pressure in the cell stack. An obstacle to be overcomed has been to ensure equalisation of the H{sub 2} and O{sub 2} pressure to avoid that mixing of gasses can occur. To solve this problem, a special equilibrium valve has been developed to mechanically control that the pressure of the H{sub 2} at all times equals the O{sub 2} side. The developments have resulted in a stack design, which is a cylindrical pressure vessel, with each cell having a cell ''wall'' sufficiently thick, to resist the high pressure and sealed with O-rings for perfect sealing at high pressures. The stack has in test proved to resist a pressure on 45 bar, though some adjustment is still needed to optimize the pressure resistance and efficiency. When deciding on the new stack design both a 'zero gap' and 'non-zero gap' was considered. The zero gap design is more efficient than non-zero gap, however the design is more complex and very costly, primarily because the additional materials and production costs for zero gap electrodes. From these considerations, the concept of a ''low gap'', low diameter, high pressure and high cell number electrolyser stack was born, which could offer an improved efficiency of the electrolyser without causing the same high material and production cost as a zero gap zero gap solution. As a result the low gap design and pressurized stack has reduced the price by 60% of the total system, as well as a reduced system footprint. The progress of the project required a special focus on corrosion testing and examination of polymers in order to find alternative durable membrane and gasket materials. The initial literature survey and the first tests indicated that the chemical resistance of polymers presented a greater challenge than anticipated, and that test data from commercial suppliers were insufficient to model the conditions in the electrolyser. The alkali resistant polymers (e.g. Teflon) are costly and the search for cheaper alternatives turned into a major aim. A number of different tests were run under accelerated conditions and the degradation mechanism was examined. One of the strong visions for the 2{sup nd} generation electrolyser concept has been to develop a modular system with several standardized components. The following modules have been designed: 1) Electrolyser module; 2) Deoxer Module; 3) Dryer Module; 4) Water Treatment Module; 5) Power supply and Control unit; 6) Rack mount. The developed 2{sup nd} generation rack-mounted alkaline electrolyser system has been installed and demonstrated for 18 month in a college (H2College) with 66 apartments. A number of measurements were performed on the system installed in H2College. No measurements on the overall system efficiency were conducted. However measurement on the stack showed a stack efficiency of 86.5% at a current density of 177mA/cm{sup 2} and a temperature of 74.4 deg. C at the hydrogen outlet. The system is estimated to have run roughly 2000h during the demonstration period. The demonstration of the 2{sup nd} generation alkaline electrolyser is considered a success for several reasons. While not all technical goals were reached, the research and development in the project have resulted in some very good solutions for most of the challenges in high pressure alkaline electrolysis. The concept of a rack mounted electrolyser was proven viable, and all critical aspects of the modularisation have been covered. (LN)
