  1. The 4th international colloquium on process simulation. Proceedings

    Jokilaakso, A. [Helsinki Univ. of Technology, Otaniemi (Finland). Dept. of Materials Science and Metallurgy

    1997-12-31

    The papers collected in this volume were presented at the 4th Colloquium on Process Simulation held at Helsinki University of Technology, Espoo, Finland, June 11-13, 1997. In the more developed industrial nations, the processes for producing chemicals, energy, and materials encounter environmental concern and laws which challenge engineers to develop the processes towards more efficient, economical and safe operation. This necessitates more thorough understanding of the processes and phenomena involved. Formerly, the development of the processes was largely based on trial and error, whereas today, the development of computer performance together with the diversification of modelling software enables simulation of the processes. The increased capacity and possibilities for modelling the processes brought by the improved hardware and software, have generated a strong demand for more accurate mathematical descriptions of the processes. Especially, the coupling of computational fluid dynamics and chemical kinetics, combustion, and thermodynamics is of current interest in process oriented technology. This colloquium attempts to give examples of modelling efforts in operation in different universities, research institutes and companies. Furthermore, the aim of this colloquium is to offer an annual opportunity to the researchers to come together and discuss their common problems and the state of their investigations

    The 4th WCRP International Conference on Reanalyses provided an opportunity for the international community to review and discuss the observational and modelling research, as well as process studies and uncertainties associated with reanalysis of the Earth System and its components. Characterizing the uncertainty and quality of reanalyses is a task that reaches far beyond the international community of producers, and into the interdisciplinary research community, especially those using reanalysis products in their research and applications. Reanalyses have progressed greatly even in the last 5 years, and newer ideas, projects and data are coming forward. While reanalysis has typically been carried out for the individual domains of atmosphere, ocean and land, it is now moving towards coupling using Earth system models. Observations are being reprocessed and they are providing improved quality for use in reanalysis. New applications are being investigated, and the need for climate reanalyses is as strong as ever. At the heart of it all, new investigators are exploring the possibilities for reanalysis, and developing new ideas in research and applications. Given the many centres creating reanalyses products (e.g. ocean, land and cryosphere research centres as well as NWP and atmospheric centers), and the development of new ideas (e.g. families of reanalyses), the total number of reanalyses is increasing greatly, with new and innovative diagnostics and output data. The need for reanalysis data is growing steadily, and likewise, the need for open discussion and comment on the data. The 4th Conference was convened to provide a forum for constructive discussion on the objectives, strengths and weaknesses of reanalyses, indicating potential development paths for the future.

    Hrvoje Petek

    2005-01-26

    The 4-th International Symposium on Ultrafast Surface Dynamics (UDS4) was held at the Telluride Summer Research Center on June 22-27, 2003. The International Organizing Committee consisting of Hrvoje Petek (USA), Xiaoyang Zhu (USA), Pedro Echenique (Spain) and Maki Kawai (Japan) brought together a total of 51 participants 16 of whom were from Europe, 10 from Japan, and 25 from the USA. The focus of the conference was on ultrafast electron or light induced processes at well-defined surfaces. Ultrafast surface dynamics concerns the transfer of charge and energy at solid surfaces on the femtosecond time scale. These processes govern rates of fundamental steps in surface reactions, interfacial electron transfer in molecular electronics, and relaxation in spin transport. Recent developments in femtosecond laser technology make it possible to measure by a variety of nonlinear optical techniques directly in the time domain the microscopic rates underlying these interfacial processes. Parallel progress in scanning probe microscopy makes it possible at a single molecular level to perform the vibrational and electronic spectroscopy measurements, to induce reactions with tunneling electrons, and to observe their outcome. There is no doubt that successful development in the field of ultrafast surface dynamics will contribute to many important disciplines.

  12. FOREWORD: 4th International Workshop on New Computational Methods for Inverse Problems (NCMIP2014)

    2014-10-01

    This volume of Journal of Physics: Conference Series is dedicated to the scientific contributions presented during the 4th International Workshop on New Computational Methods for Inverse Problems, NCMIP 2014 (http://www.farman.ens-cachan.fr/NCMIP_2014.html). This workshop took place at Ecole Normale Supérieure de Cachan, on May 23, 2014. The prior editions of NCMIP also took place in Cachan, France, firstly within the scope of ValueTools Conference, in May 2011 (http://www.ncmip.org/2011/), and secondly at the initiative of Institut Farman, in May 2012 and May 2013, (http://www.farman.ens-cachan.fr/NCMIP_2012.html), (http://www.farman.ens-cachan.fr/NCMIP_2013.html). The New Computational Methods for Inverse Problems (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 finances. 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

  13. Operation of Finnish nuclear power plants. Quarterly report, 4th quarter 1996

    Quarterly reports on the operation of Finnish nuclear power plants describe events and observations relating to nuclear and radiation safety which the Finnish Centre for Radiation and Nuclear Safety (STUK) considers safety significant. Safety improvements at the plants are also described. The report also includes a summary of the radiation safety of plant personnel and of the environment and tabulated data on the plants's production and load factors. In the fourth quarter of 1996, the Finnish nuclear power plant units were in power operation except for the annual maintenance outage of Loviisa 2 and a shutdown at Olkiluoto 1 to repair a condensate system stop valve. The load factor average of all plant units was 96.5%. Events in the fourth quarter of 1996 were level 0 on the International Nuclear Event Scale. Occupational doses and radioactive releases off-site were below authorised limits. Radioactive substances were measurable in samples collected around the plants in such quantities only as have no bearing on the radiation exposure of the population. (orig.)

  5. Proceedings of the 4th international symposium on material testing reactors

    This report is the Proceedings of the fourth International Symposium on Material Testing Reactors hosted by Japan Atomic Energy Agency (JAEA). The first symposium was held on 2008, at the Oarai Research and Development Center of JAEA, the second, 2009, Idaho National Laboratory (INL) of United States and the third 2010, Nuclear Research Institute (NRI) in Czech Republic to exchange information for deep mutual understanding of material testing reactors. The fourth symposium was originally scheduled to be held INVAP in Argentina. However, the aftermath of volcanic explosion at Chili forced the symposium to change place. Total 111 participants attended from Argentina, Belgium, France, Germany, Indonesia, Malasia, Korea, South Africa, Switzerland, the United State and Japan. This symposium addressed the general topics of 'status and future plan of material testing reactors', 'advancement of irradiation technology', 'expansion of industry use(RI)', 'facility, upgrade, aging management', 'new generation MTR', 'advancement of PIE technology', 'development of advanced driver fuel', and 'nuclear human resource development(HRD) for next generation', and 39 presentations were made. Furthermore, three topics, 'Necessity of cooperation for Mo-99 production by (n,gamma) reaction', 'Necessity of standardization of irradiation technology' and 'Conceptual design of next generation materials testing reactor by collaboration', were selected and discussed.

  6. 4th CIRP International Conference on Industrial Product-Service Systems

    Kimita, Koji

    2013-01-01

    Industrial Product-Service Systems (IPS2), which is defined as “an integrated industrial product and service offering that delivers value in use,” has expanded rapidly over the last decade. IPS2 has allowed us to achieve both high added value and high productivity and has enriched our QOL by improving the performance of products and services. We are now struggling with many awkward issues related to sustainability, but IPS2 is expected to be the “philosopher’s stone” for solving these issues. Following the pattern of conferences held in Cranfield in 2009, Linköping in 2010, and Braunschweig in 2011, the fourth International CIRP Conference on Industrial Product-Service Systems, held on November 8-9, 2012, in Tokyo, will cover various aspects of IPS2. Topics planned for this year’s conference reflect the latest IPS2 information in both the natural sciences and humanities and include case studies from various industries. IPS2 is still a relatively new field, so it is important to keep track of the ...

  7. Abstracts of the 4th International MELODI Workshop 12 -14 September 2012, Helsinki, Finland

    Sulonen, N. (ed.)

    2012-08-15

    The Fourth International MELODI Workshop is organized by STUK - Radiation and Nuclear Safety Authority in Helsinki, Finland, on 12-14 September 2012. The workshop offers an update of recent low-dose research issues, and an opportunity to participate in the MELODI Low Dose Research Platform, a major step in the long term goals that the European Low-Dose Risk research intends to achieve. The main goal of MELODI is to develop and maintain a Strategic Research Agenda (SRA) in the field of low-dose radiation research, and to actively promote its implementation. DoReMi Network of Excellence funded by the European Commission is supporting the setting up of the Platform and addressing some of its research needs. In line with one of the main SRA goals, a major aim of the workshop was to set all topics in an interdisciplinary context. The Workshop abstracts cover plenary lectures as well as poster presentations related to topical discussions in breakout sessions. The theme of the first day 'Low dose risk research - state of the art' provides an introduction to the MELODI activities and the SRA and an update on recent epidemiological studies and dosimetric aspects of low dose studies. Potential implications of cardiovascular disease risk for radiation protection are also addressed. Discussion on the state-of-the art of MELODI SRA took place in three break-out groups addressing epidemiological approaches, cancer mechanisms and models and infrastructures and knowledge management. The second day 'Emerging scientific challenges' features the development of science and novel technologies, covering topics such as epigenetics, systems biology, stem cells as well as biomarkers that could be potentially used in molecular epidemiological studies. The associated breakout sessions explore the roadmap for future research, covering themes on biomarkers and biobanks, non-cancer effects, as well as low dose dosimetry and dose concept. The third day 'Integrating the

  8. Editorial. Special issue of Classical and Quantum Gravity on the proceedings of the 4th international LISA symposium

    The 4th International LISA Symposium was held at the National Science Foundation Physics Frontier Center for Gravitational Wave Physics at The Pennsylvania State University on 19-24 July 2002. This special issue of Classical and Quantum Gravity is the proceedings of this meeting. LISA - the Laser Interferometer Space Antenna - is part of an international effort to open a new window on the universe. Not all things radiate light, but everything gravitates. Observations of the gravitational waves radiated by black holes and compact binary star systems, in our galaxy and beyond, can reveal details about these systems and their environments that are otherwise inaccessible. The international effort, of which LISA is a part, includes ground-based detectors, and the relationship between LISA and its ground-based detector 'cousins' was an important theme for this Symposium. LISA will observe gravitational waves in the 0.1 mHz to 0.1 Hz band, complementing observations made by ground-based detectors in the 10 Hz to several KHz band. Together they will explore nearly six decades of bandwidth in the gravitational-wave sky. LISA in particular will observe the gravitational waves radiated by the coalescence of black holes at the centres of colliding galaxies, and the inspiral of compact neutron stars or stellar-mass black holes onto these black holes, virtually anywhere in the universe. It will take a census of neutron star or close white dwarf binaries in our own galaxy and observe the formation of large black holes from the very first structures to form and collapse in our universe. In doing all these things, it will shed new 'light' on the first structures to form in the universe, explore the evolution of galaxies and the roles that black holes play in their structure, test relativity near the 'edges' of a black hole, and deepen our understanding of stellar and binary system evolution. A successful conference - and this LISA Symposium, like its predecessors, was very

  9. First TRUE Stage - Transport of solutes in an interpreted single fracture. Proceedings from the 4th international seminar

    . The outcome of the 4th International Aespoe seminar focused on the TRUE-1 experiments can be summarised in the following main points: There is a general consensus that the observed retardation observed in the TRUE-1 experiments requires diffusion into geological material to be an active process. This supported by the -3/2 slope noted in log-log BTCs. Whether this is due to diffusion (and subsequent sorption) in the altered matrix rock, or in possible fault gouge cannot be differentiated with available data; Some researchers claim that the observed enhanced retardation may be explained by diffusion into stagnant water pools, pure surface sorption, or may be due to an underestimation in the flow-wetted surface area. The latter effect may be attributed to a more complex flow path (multi-layered structure) or three-dimensional effects; A clear differentiation between the principal active process can only assessed by resin injection and subsequent excavation and analysis; It was identified that experiments of TRUE type are important for improving the understanding of retention processes. However, this type of experiment will not be part of a site characterisation programme; It was recommended to broaden the data base from the TRUE-1 site before characterising pore space with resin techniques. This includes tracer dilution tests using sinks in other features than Feature A. The seminar was divided into four sessions: 1. Detailed characterisation of transport-related properties (Three contributions separately indexed). 2. Alternative evaluation of TRUE-1 results (Five contributions separately indexed). 3. Related studies (Three contributions separately indexed). 4. Understanding of retention processes in a single fracture (Two contributions separately indexed)

    Kim, Byoung Chul; Lee, Sam Lai; Choi, Kwon Jae [Korea Atomic Energy Research Institute, Taejeon (Korea)

    2001-08-01

    Surveillance testing for reactor vessel materials is performed in order to evaluate the irradiation embrittlement due to neutrons during operation and set the condition of safe operation of nuclear reactor. The 4th surveillance testing was performed completely by Korea Atomic Energy Research Institute at Taejeon after the capsule was transported from Yonggwang site including its removal from reactor. Fast neutron fluences for capsules were calculated and various testing including mechanical and chemistry analysis were performed in order to evaluate the integrity of Yonggwang unit 1 reactor vessel during the operation until life time. The evaluation results are as follows; Fast neutron fluences for capsules U, V, X and W are 5.555E+18, 1.662E+19, 3.358E+19, and 4.521E+19 n/cm{sup 2}, respectively. The bias factor, the ratio of measurement versus calculation, was 0.859 for the 1st through 4th testing and the calculational uncertainty, 11.80% satisfied the requirement of USNRC Reg.Guide 1.190, 20%. The best estimated neutron fluence for reactor vessel inside surface was 1.551E+19 n/cm{sup 2} based on the end of 12th fuel cycle and it was predicted that the fluences of vessel inside surface at 32, 40, 48 and 56EFPY would reach 3.929E+19, 4.880E+19, 5.831E+19 and 6.782E+19 n/cm{sup 2} based on the current calculation. The result through this analysis for Yonggwang unit 1 showed that there would be no problem for the pressurized thermal shock(PTS) during the operation until design life. 4 refs., 41 figs., 35 tabs.

  18. The 4th Thermodynamic Principle?

    It should be emphasized that the 4th Principle above formulated is a thermodynamic principle and, at the same time, is mechanical-quantum and relativist, as it should inevitably be and its absence has been one of main the theoretical limitations of the physical theory until today.We show that the theoretical discovery of Dimensional Primitive Octet of Matter, the 4th Thermodynamic Principle, the Quantum Hexet of Matter, the Global Hexagonal Subsystem of Fundamental Constants of Energy and the Measurement or Connected Global Scale or Universal Existential Interval of the Matter is that it is possible to be arrived at a global formulation of the four 'forces' or fundamental interactions of nature.

    Full Text Available This contribution is based on the discussions that took place in the international conference “Bridging the Gap between International Investment Law and the Environment” which was held on 4-5 November 2013 in the Hague. The main goal of the conference was to answer the question of how the gap between international investment law and the environment can be bridged. Different perspectives were presented, helping to shed light on this issue. The emphasis of the first day of the conference was the academic debate in the field of international investment law and the environment. Four main perspectives were discussed: general principles of international investment law and the environment, various legal regimes, specific legal regimes and case studies. Furthermore, also the topics of sustainable development, the right to access to water and climate change were elaborated upon by the experts. The second day of the conference focussed on the perspective of policy-makers. Most of the topics were presented in the form of panel discussions. Issues that were discussed included: the perspective of various intergovernmental organisations, concerns and dilemmas of non-European capital-importing countries, and the European Investment Policy. This contribution elaborates upon the most important themes and issues debated at the conference, providing academic and policy perspectives.

  2. FOREWORD: The 4th CCM International Conference on Pressure Metrology from Ultra-High Vacuum to Very High Pressures (10-9 Pa to 109 Pa)

    Legras, Jean-Claude; Jousten, Karl; Severn, Ian

    2005-12-01

    The fourth CCM (Consultative Committee for Mass and related quantities) International Conference on Pressure Metrology from Ultra-High Vacuum to Very High Pressures (10-9 Pa to 109 Pa) was held at the Institute of Physics in London from 19-21 April 2005. The event, which was organized by the Low, Medium and High Pressure working groups of the CCM, was attended by in excess of one hundred participants with representatives from five continents and every regional metrology organization. The purpose of this conference is to review all the work that is devoted to the highest quality of pressure measurement by primary standards as well as the dissemination of the pressure scale. A total of 52 papers were presented orally, and 26 as posters, in sessions that covered the following topics: Latest scientific advances in pressure and vacuum metrology Innovative transfer standards, advanced sensors and new instrument development Primary (top-level) measurement standards International and regional key comparisons New approaches to calibration It is interesting the note that since the third conference in 1999 the pressure range covered has increased by two orders of magnitude to 109 Pa, to take into account more exacting scientific and industrial demands for traceable vacuum measurement. A further feature of the conference was the increased range of instrumentation and techniques used in the realization and potential realization of pressure standards. Seton Bennett, Director of International Metrology at the National Physical Laboratory, opened the conference and Andrew Wallard, Director of the Bureau International des Poids et Mesures (BIPM), gave the keynote address which described the implementation of the mutual recognition arrangement and the resulting removal of metrological barriers to international trade. Many experts have contributed significant amounts of their time to organize the event and to review the submitted papers. Thanks are due to all of these people

  7. 4th International Symposium on Ambient Intelligence

    Hallenborg, Kasper; Rodríguez, Juan; Tapia, Dante; Novais, Paulo

    2013-01-01

    Ambient Intelligence (AmI) is a recent paradigm emerging from Artificial Intelligence (AI), where computers are used as proactive tools assisting people with their day-to-day activities, making everyone’s life more comfortable. Another main concern of AmI originates from the human computer interaction domain and focuses on offering ways to interact with systems in a more natural way by means user friendly interfaces. This field is evolving quickly as can be witnessed by the emerging natural language and gesture based types of interaction. The inclusion of computational power and communication technologies in everyday objects is growing and their embedding into our environments should be as invisible as possible. In order for AmI to be successful, human interaction with computing power and embedded systems in the surroundings should be smooth and happen without people actually noticing it. The only awareness people should have arises from AmI: more safety, comfort and wellbeing, emerging in a natural and inh...

  9. MicroRNAs in Cancer: the 22nd Hiroshima Cancer Seminar/the 4th Japanese Association for RNA Interference Joint International Symposium, 30 August 2012, Grand Prince Hotel Hiroshima.

    Tahara, Hidetoshi; Kay, Mark A; Yasui, Wataru; Tahara, Eiichi

    2013-05-01

    The joint international symposium of the 22nd Hiroshima Cancer Seminar and the 4th Japanese Association for RNA Interference focused on a pivotal role of microRNAs in carcinogenesis, progression and therapy of human cancer. Mammalian immune regulator MCPIP1 (Zc3h12a) RNase acts as a novel suppressor of microRNA activity and biogenesis, suggesting the involvement of MCPIP1 in the alteration of microRNA biogenesis in tumorigenesis. Gene set enrichment analysis and functional assignment of microRNAs via enrichment analysis enable the prediction of microRNA activities from mRNA expression data by combining rank-based enrichment analysis and weighted evaluation of microRNA-mRNA interactions. MiR-124 and miR-203 function as tumor-suppressor microRNAs silenced by DNA methylation in hepatocellular carcinoma. Stella-induced DNA hypomethylation would confer the pathogenic function of DNA hypomethylation in cancer. Senescence-associated microRNA, miR-22, suppresses tumor growth and metastasis in vivo in a murine breast cancer model, and exosomal senescence-associated microRNA may affect the tumor microenvironment. The therapeutic potential of microRNAs for preventing and treating lung cancer using the Kras(LSL-G12D/+);p53(LSL-R172H/+)mouse model suggests that miR-34 may be useful in sensitizing tumors to other conventional therapeutics. MiR-1 and miR-133a cluster may function as tumor suppressors regulating novel pathways in human cancers. The down-regulation of miR-148a is implicated in invasion of gastric cancer, while high miR-21 expression in colorectal cancer is associated with poor survival. Neutral sphingomyelinase 2 regulates exosomal microRNA secretion and promotes angiogenesis within the tumor microenvironment as well as metastasis; in particular, the exosomal miR-210 secretion by neutral sphingomyelinase 2 confers the formation of the tumor vessel network.

  13. 4th Generation District Heating (4GDH)

    Lund, Henrik; Werner, Sven; Wiltshire, Robin;

    2014-01-01

    This paper defines the concept of 4th Generation District Heating (4GDH) including the relations to District Cooling and the concepts of smart energy and smart thermal grids. The motive is to identify the future challenges of reaching a future renewable non-fossil heat supply as part of the...... implementation of overall sustainable energy systems. The basic assumption is that district heating and cooling has an important role to play in future sustainable energy systems – including 100 percent renewable energy systems – but the present generation of district heating and cooling technologies will have...... to be developed further into a new generation in order to play such a role. Unlike the first three generations, the development of 4GDH involves meeting the challenge of more energy efficient buildings as well as being an integrated part of the operation of smart energy systems, i.e. integrated smart...

  14. Search for 4th generation quarks

    Khalil, Sadia

    2013-01-01

    We present the results of searches for a new heavy 4th generation and vector-like quark using leptonic, and semileptonic final states comprising of electron(s) and/or muon(s) and jets. The full sample of 5 fb$^{-1}$ of pp collisions recorded with CMS experiment in 2011 at the center-of-mass energy of 7 TeV has been used. In leptonic final states, two same sign dilepton and trilepton channels have been explored. For semileptonic events, the search for heavy quarks is carried out using events with one lepton, and at least four jets with imbalance in transverse momenta, requiring at least one of the jet identified as originating from the fragmentation of a b-quark. No significant excess of events over Standard Model expectations is observed, therefore upper mass limits are set at 95\\% C.L.

  17. 4th generation light source instrumentation

    This working group on 4th Generation Light Source (4GLS) Instrumentation was a follow-up to the opening-discussion on Challenges in Beam Profiling. It was in parallel with the Feedback Systems session. We filled the SSRL Conference Room with about 25 participants. The session opened with an introduction by Lumpkin. The target beam parameter values for a few-angstrom, self-amplified spontaneous emissions (SASE) experiment and for a diffraction-limited soft x-ray storage ring source were addressed. Instrument resolution would of course need to be 2-3 times better than the value measured, if possible. The nominal targeted performance parameters are emittance (1-2π mm mrad), bunch length (100 fs), peak-current (l-5 kA), beam size (10 microm), beam divergence (1 microrad), energy spread (2 x 10-4), and beam energy (10's of GeV). These are mostly the SASE values, and the possible parameters for a diffraction-limited soft x-ray source would be relaxed somewhat. Beam stability and alignment specifications in the sub-micron domain for either device are anticipated

  18. 4th Workshop on Combinations of Intelligent Methods and Applications

    Palade, Vasile; Prentzas, Jim

    2016-01-01

    This volume includes extended and revised versions of the papers presented at the 4th Workshop on “Combinations of Intelligent Methods and Applications” (CIMA 2014) which was intended to become a forum for exchanging experience and ideas among researchers and practitioners dealing with combinations of different intelligent methods in Artificial Intelligence. The aim is to create integrated or hybrid methods that benefit from each of their components. Some of the existing presented efforts combine soft computing methods (fuzzy logic, neural networks and genetic algorithms). Another stream of efforts integrates case-based reasoning or machine learning with soft-computing methods. Some of the combinations have been more widely explored, like neuro-symbolic methods, neuro-fuzzy methods and methods combining rule-based and case-based reasoning. CIMA 2014 was held in conjunction with the 26th IEEE International Conference on Tools with Artificial Intelligence (ICTAI 2014). .

  11. International safeguards for reprocessing plants. Final report

    Proliferation risks inherent in reprocessing show the need to employ technically effective safeguards which can detect, with a high degree of assurance and on a timely basis, the diversion of significant quantities of fissionable material. A balance must be struck between what is technically feasible and effective and what is institutionally acceptable. Purpose of this report is to examine the several technical approaches to safeguards in light of their prospective acceptability. This study defines the economic, political and institutional nature of the safeguards problem; surveys generically alternative technical approaches to international safeguards including their effectiveness and relative development; characterizes the institutional implications and uncertainties associated with the acceptance and implementation of each technical alternative; and integrates these assessments into a set of overall judgments on feasible directions for reprocessing plant safeguards systems

  14. Validation of CO 4th positive radiation for Mars entry

    This paper presents measurements and simulations of CO 4th Positive equilibrium radiation obtained in the NASA Ames Research Center's Electric Arc Shock Tube (EAST) facility. The experiments were aimed at measuring the level of radiation encountered during conditions relevant to high-speed entry into a simulated Martian atmosphere (96% CO2: 4% N2). The facility was configured to target several ranges of nominal Mars entry conditions, of which 7.35 km/s at 0.1 Torr (13.3 Pa), 6.2–8 km/s at 0.25 Torr (33 Pa) and 7.1–7.8 km/s at 1 Torr (133 Pa) are examined in this paper. The CO 4th Positive system was chosen to be the focus of this study as it accounts for a large percentage of the emitted radiation for Martian entry, and also due to the difficulties of obtaining experimental validation data due to the emission appearing in the Vacuum Ultra Violet (VUV) spectral range. The focus of this paper is to provide a comprehensive comparison between the EAST data and various CO 4th Positive databases available in the literature. The analysis endeavors to provide a better understanding of the uncertainty in the measurements and quantifies the level of agreement found between simulations and experimental data. The results of the analysis show that the magnitude of the CO 4th Positive radiative intensity is very sensitive to the flow temperature. Subsequently, simulations using thermodynamic equilibrium generally under-predict the experimental data by approximately a factor of up to 2. However, when simulations are performed using a flow temperature extracted from the black body limited portion of the CO 4th Positive spectra taken from experiment, the agreement between the EAST data and simulations is generally very good. Furthermore, comparisons of experimental data and simulations across other spectral regions provide additional support for the use of the black body temperature. -- Highlights: ► Measurements and simulations of CO 4th Positive radiation are presented.

  4. EXTERNAL AND INTERNAL CONTROL IN PLANT DEVELOPMENT

    Beáta Oborny

    2003-01-01

    Bodies of plants are modularly organized. Development proceeds by adding new modules to open endings with a potential for branching. Each module is autonomous to some extent. Development relies on the self-organized patterns that emerge from the interactions of individual modules. Interactions include both competition and cooperation, and several types of positive and negative feedback loops are involved. Development can be open to external influences, thus enabling the plant to adjust its form to the environment, for example, to the spatial distribution of ecological resources. This paper provides a review on adaptive plasticity in plants.

  12. Energy supply the 4th quarter and the whole years 2001 and 2002. Preliminary data

    The final consumption of energy in Sweden the 4th quarter 2002 increased by 8 per cent compared to the corresponding period 2001, from 106 TWh to 114 TWh. The consumption within industrial sector and transport sector increased by 3 per cent each and household sector increased by 14 per cent. The energy consumption during 2002 was 400 TWh, which is an increase by 1 per cent since 2001 when the consumption was 394 TWh. The consumption in industry sector rose by 3 per cent, which can be explained by an increase of using district heating. This quarter has the use increased from 6.0 PJ to 8.9 PJ which responds to an 48 per cent increase. It is the rising activity with ready made heat that explains this figures. Ready made heat is when the energy sector runs the boilers that used to belong to the industries. The fuel input, of for instance biomass fuel, could earlier be found within industry whereas nowadays the fuel input is within the energy sector. The gross supply of energy in Sweden the 4th quarter 2002 increased by 7 per cent compared to the 4th quarter 2001. The production of electricity from nuclear plants was 5 per cent lower compared with the same quarter 2001. Hydroelectric power production decreased by 29 per cent during the same period. The supply of natural gas rose by 17 per cent and the supply of domestic fuels rose by 13 per cent. The supply of coal and coke increased by 14 per cent and there was an 17 per cent increase in the supply of oil products. The total gross supply of energy was unchanged during 2002 compared with 2001. But we can see an increase in the supply of coal and coke, 4 per cent, domestic fuels, 5 per cent, oil products, 3 per cent and district heating, 4 per cent

    Many terrestrial ecosystem processes are constrained by water availability and transport within the soil. Knowledge of plant water fluxes is thus critical for assessing mechanistic processes linked to biogeochemical cycles, yet resolution of root structure and xylem water transport dynamics has been a particularly daunting task for the ecologist. Through neutron imaging, we demonstrate the ability to non-invasively monitor individual root functionality and water fluxes within Zea mays L. (maize) and Panicum virgatum L. (switchgrass) seedlings growing in a sandy medium. Root structure and growth were readily imaged by neutron radiography and neutron computed tomography. Seedlings were irrigated with water or deuterium oxide and imaged through time as a growth lamp was cycled on to alter leaf demand for water. Sub-millimeter scale resolution reveals timing and magnitudes of root water uptake, redistribution within the roots, and root-shoot hydraulic linkages, relationships not well characterized by other techniques.

  14. The "4th generation", B-CP anomalies & the LHC

    Soni, Amarjit

    2009-01-01

    Attention is drawn to the several 2-3 $\\sigma$ "anomalies" in B, $B_s$ mixings and decays involving CP-observables. Perhaps the most interesting theoretical scenario that could cause such effects is based on warped extra-dimensional models and indeed some of the effects were predicted there. However, a rather simple explanation is that based on a fourth family of quarks with masses in the range of(400 - 600) GeV. The built-in hierarchy of the 4$\\times$4 mixing matrix is such that the $t'$ readily provides a needed {\\it perturbation} ($\\approx 15%$) to $\\sin 2 \\beta$ as measured in $B \\to \\psi K_s$ and simultaneously is the dominant source of CP asymmetry in $B_s \\to \\psi \\phi$. The latter mode is theoretically very clean (unlike the others) and therefore it would be extremely desirable that Fermilab gives a very high priority to clarify this anomaly at the earliest. 4th family explanation allows, with relative ease, to accomodate the stringent flavor changing constraints which usually can be quite challenging...

    1988-01-01

    This volume contains a collection of 23 papers presented at the 4th French-German Conference on Optimization, hold at Irsee, April 21 - 26, 1986. The conference was aUended by ninety scientists: about one third from France, from Germany and from third countries each. They all contributed to a highly interesting and stimulating meeting. The scientifique program consisted of four survey lectures of a more tutorical character and of 61 contributed papers covering almost all areas of optimization. In addition two informal evening sessions and a plenary discussion on further developments of optimization theory were organized. One of the main aims of the organizers was to indicate and to stress the increasing importance of optimization methods for almost all areas of science and for a fast growing number of industry branches. We hope that the conference approached this goal in a certain degree and managed to continue fruitful discussions between -theory­ and -applications-. Equally important to the official contri...

  17. European Code against Cancer 4th Edition: Diet and cancer.

    Lifestyle factors, including diet, have long been recognised as potentially important determinants of cancer risk. In addition to the significant role diet plays in affecting body fatness, a risk factor for several cancers, experimental studies have indicated that diet may influence the cancer process in several ways. Prospective studies have shown that dietary patterns characterised by higher intakes of fruits, vegetables, and whole-grain foods, and lower intakes of red and processed meats and salt, are related to reduced risks of death and cancer, and that a healthy diet can improve overall survival after diagnosis of breast and colorectal cancers. There is evidence that high intakes of fruit and vegetables may reduce the risk of cancers of the aerodigestive tract, and the evidence that dietary fibre protects against colorectal cancer is convincing. Red and processed meats increase the risk of colorectal cancer. Diets rich in high-calorie foods, such as fatty and sugary foods, may lead to increased calorie intake, thereby promoting obesity and leading to an increased risk of cancer. There is some evidence that sugary drinks are related to an increased risk of pancreatic cancer. Taking this evidence into account, the 4th edition of the European Code against Cancer recommends that people have a healthy diet to reduce their risk of cancer: they should eat plenty of whole grains, pulses, vegetables and fruits; limit high-calorie foods (foods high in sugar or fat); avoid sugary drinks and processed meat; and limit red meat and foods high in salt.

    2001-01-01

    We analyze the determinants of the decision to invest abroad in particular configurations of overseas plants for 120 Japanese firms active in 36 well-defined electronic product markets. We find support for a structured internationalization decision model in which the decision to produce abroad and the choice for a specific international plant configuration are treated as nested strategic options. Drivers at the industry and firm level push firms to consider overseas investment, and locational...

  19. Demonstration of direct internal reforming for MCFC power plants

    1996-12-31

    The conversion of methane into hydrogen for an MCFC by steam reforming is accomplished either externally or internally in the stack. In the case of external reforming the plant electrical efficiency is 5% abs. lower mainly because more parasitic power is required for air compression for stack cooling. Furthermore, heat produced in the stack must be transferred to the external reformer to drive the endothermic steam reforming reaction giving a more complex plant lay-out. A more suitable and cost effective approach is to use internal steam reforming of methane. Internal reforming may be accomplished either by Indirect Internal Reforming (DIR) and Direct Internal Reforming (DIR) in series or by DIR-only as illustrated. To avoid carbon formation in the anode compartment higher hydrocarbons in the feedstock are converted into hydrogen, methane and carbon oxides by reaction with steam in ail adiabatic prereformer upstream the fuel cell stack. This paper discusses key elements of the desire of both types of internal reforming and presents data from pilot plants with a combined total of more than 10,000 operating hours. The project is being carried out as part of the activities of the European MCFC Consortium ARGE.

  20. Growth Chambers on the International Space Station for Large Plants

    Massa, Gioia D.; Wheeler, Raymond M.; Morrow, Robert C.; Levine, Howard G.

    2016-01-01

    The International Space Station (ISS) now has platforms for conducting research on horticultural plant species under LED (Light Emitting Diodes) lighting, and those capabilities continue to expand. The Veggie vegetable production system was deployed to the ISS as an applied research platform for food production in space. Veggie is capable of growing a wide array of horticultural crops. It was designed for low power usage, low launch mass and stowage volume, and minimal crew time requirements. The Veggie flight hardware consists of a light cap containing red (630 nanometers), blue, (455 nanometers) and green (530 nanometers) LEDs. Interfacing with the light cap is an extendable bellowsbaseplate for enclosing the plant canopy. A second large plant growth chamber, the Advanced Plant Habitat (APH), is will fly to the ISS in 2017. APH will be a fully controllable environment for high-quality plant physiological research. APH will control light (quality, level, and timing), temperature, CO2, relative humidity, and irrigation, while scrubbing any cabin or plant-derived ethylene and other volatile organic compounds. Additional capabilities include sensing of leaf temperature and root zone moisture, root zone temperature, and oxygen concentration. The light cap will have red (630 nm), blue (450 nm), green (525 nm), far red (730 nm) and broad spectrum white LEDs (4100K). There will be several internal cameras (visible and IR) to monitor and record plant growth and operations. Veggie and APH are available for research proposals.

  1. Peptic Perforation of the 4th Duodenal Segment. Case Report

    Cimpean Sorin

    2015-03-01

    Full Text Available Introduction: Even if the prevalence of peptic ulcer disease has decreased in the last years, duodenal perforation remains a life threatening complication. The duodenum is the second most common site of gastrointestinal perforations after the colon and perforation of the 4th portion is very rare. Case Presentation: A 67-yers-old man was admitted to the emergency department of the Annecy Hospital with intense abdominal pain, vomiting and no transit for the last 24 hours. The laboratory count showed an inflammatory syndrome. A CT scan revealed free air and fluid near the Treitz’s angle. An exploratory laparotomy was performed that revealed a perforation of the forth portion of the duodenum. A duodenal resection with duodeno-jejunal anastomosis was performed. Discussions: Peptic ulcer disease is a common disease and the perforation is one of its most life threatening complications. The localization of the DP on the forth segment of the duodenum is very unusual. The most frequent localization of DP is the first duodenal segment. Abdominal CT scan is the most sensitive radiological exam if there is suspicion of a DP. A Zollinger-Ellison syndrome must be taken into count. Peritonitis is an indication for immediate laparoscopy or laparotomy, taking into account the patient’s condition. Despite the successful medication therapy and the progress in treatment of duodenal ulcer, perforation remains a serious complication, requiring an emergency surgical treatment. Conclusion: Duodenal perforation of the fourth portion is an extremely rare complication of the peptic ulcer disease and the surgery is the primary modality of treatment.

  2. Plasma-Based Studies on 4th Generation Light Sources

    The construction of a short pulse tunable x-ray laser source will be a watershed for plasma-based and warm dense matter research. The areas we will discuss below can be separated broadly into warn dense matter (WDM) research, laser probing of near solid density plasmas, and laser-plasma spectroscopy of ions in plasmas. The area of WDM refers to that part of the density-temperature phase space where the standard theories of condensed matter physics and/or plasma statistical physics are invalid. Warm dense matter, therefore, defines a region between solids and plasmas, a regime that is found in planetary interiors, cool dense stars, and in every plasma device where one starts from a solid, e.g., laser-solid matter produced plasma as well as all inertial fusion schemes. The study of dense plasmas has been severely hampered by the fact that laser-based methods have been unavailable. The single most useful diagnostic of local plasma conditions, e.g., the temperature (T{sub e}), the density (n{sub e}), and the ionization (Z), has been Thomson scattering. However, due to the fact that visible light will not propagate at electron densities, n{sub e}, {ge} 10{sup 22} cm{sup -3} implies dense plasmas can not be probed. The 4th generation sources, LCLS and Tesla will remove these restrictions. Laser-based plasma spectroscopic techniques have been used with great success to determine the line shapes of atomic transitions in plasmas, study the population kinetics of atomic systems embedded in plasmas, and look at redistribution of radiation. However. the possibilities end for plasmas with n{sub e} {ge} 10{sup 22} since light propagation through the medium is severely altered by the plasma. The entire field of high Z plasma kinetics from laser produced plasma will then be available to study with the tunable source.

  3. Fukushima Nuclear Accident, the Third International Severe Nuclear Power Plant Accident

    Japan is the world's third largest power user. Japan's last remaining nuclear reactor shutdown on Saturday 4 Th of May 2012 leaving the country entirely nuclear free. All of 50 of the nation's operable reactors (not counting for the four crippled reactors at Fukushima) are now offline. Before last year's Fukushima nuclear disaster, the country obtained 30% of its energy from nuclear plants, and had planned to produce up to 50% of its power from nuclear sources by 2030. Japan declared states of emergency for five nuclear reactors at two power plants after the units lost cooling ability in the aftermath of Friday 11 March 2011 powerful earthquake. Thousands of (14000) residents were immediately evacuated as workers struggled to get the reactors under control to prevent meltdowns. On March 11 Th, 2011, Japan experienced a sever earthquake resulting in the shutdown of multiple reactors. At Fukushima Daiichi site, the earthquake caused the loss of normal Ac power. In addition it appeals that the ensuing tsunami caused the loss of emergency Ac power at the site. Subsequent events caused damage to fuel and radiological releases offsite. The spent fuel problem is a wild card in the potentially catastrophic failure of Fukushima power plant. Since the Friday's 9.0 earthquake, the plant has been wracked by repeated explosions in three different reactors. Nuclear experts emphasized there are significant differences between the unfolding nuclear crisis at Fukushima and the events leading up to the Chernobyl disaster in 1986. The Chernobyl reactor exploded during a power surge while it was in operation and released a major cloud of radiation because the reactor had no containment structure around to. At Fukushima, each reactor has shutdown and is inside a 20 cm-thick steel pressure vessel that is designed to contain a meltdown. The pressure vessels themselves are surrounded by steel-lined, reinforced concrete shells. Chernobyl disaster was classified 7 on the International

  5. The reprocessing plant as a problem of international law

    The planned construction of the reprocessing plant creates problems with regard to transfrontier environmental protection, due to the potential hazards involved, and these problems institute obligations of the Federal Republic of Germany under contractual law and under customary international law. Particularly under customary international neighbour law the F.R.G. is obliged to prevent and abstain from transfrontier activities entailing environmental effects with considerable damaging potential in the neighbouring states, which also includes the duty of providing for protection against accidents. It is, however, a clear fact that the states decided the peaceful uses of atomic energy to be admissible, and accept the risk of possible catastrophic damage. The interpretation of existing international laws has to take this fact into account. (orig./HSCH)

    International audience Historically Diffusion MRI started with Diffusion Tensor Imaging (DTI), which boosted the development of schemes for estimating positive definite tensors but were limited by their inability to detect fiber-crossings. Recent HARDI techniques have overcome that shortcoming with a plethora of new reconstruction schemes such as radial basis functions, Spherical Harmonics (SH), Higher Order Tensors (HOT), etc. It is appropriate, therefore, to explore HOT while leveraging ...

  12. Nitric Oxide Improves Internal Iron Availability in Plants1

    Graziano, Magdalena; Beligni, María Verónica; Lamattina, Lorenzo

    2002-01-01

    Iron deficiency impairs chlorophyll biosynthesis and chloroplast development. In leaves, most of the iron must cross several biological membranes to reach the chloroplast. The components involved in the complex internal iron transport are largely unknown. Nitric oxide (NO), a bioactive free radical, can react with transition metals to form metal-nitrosyl complexes. Sodium nitroprusside, an NO donor, completely prevented leaf interveinal chlorosis in maize (Zea mays) plants growing with an iron concentration as low as 10 μm Fe-EDTA in the nutrient solution. S-Nitroso-N-acetylpenicillamine, another NO donor, as well as gaseous NO supply in a translucent chamber were also able to revert the iron deficiency symptoms. A specific NO scavenger, 2-(4-carboxy-phenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, blocked the effect of the NO donors. The effect of NO treatment on the photosynthetic apparatus of iron-deficient plants was also studied. Electron micrographs of mesophyll cells from iron-deficient maize plants revealed plastids with few photosynthetic lamellae and rudimentary grana. In contrast, in NO-treated maize plants, mesophyll chloroplast appeared completely developed. NO treatment did not increase iron content in plant organs, when expressed in a fresh matter basis, suggesting that root iron uptake was not enhanced. NO scavengers 2-(4-carboxy-phenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide and methylene blue promoted interveinal chlorosis in iron-replete maize plants (growing in 250 μm Fe-EDTA). Even though results support a role for endogenous NO in iron nutrition, experiments did not establish an essential role. NO was also able to revert the chlorotic phenotype of the iron-inefficient maize mutants yellow stripe1 and yellow stripe3, both impaired in the iron uptake mechanisms. All together, these results support a biological action of NO on the availability and/or delivery of metabolically active iron within the plant. PMID:12481068

  14. Integrating plant-internal and plant-external information systems for optimal handling of nuclear emergencies

    The handling of nuclear emergencies is a complex task, which may involve rescue personnel at the emergency site as well as personnel residing at significant distance from the disaster area. This paper will focus on integration of support systems for use in emergencies arising from nuclear power plant accidents and will cover both plant-internal and plant-external aspects. The different decision centers being involved in management of nuclear accidents, the plant control room, the technical support center and the regional and national emergency centers, are briefly described and focus is placed on the utilization of a common information base, containing basic information being presented at an inter-center level. The utilization of advanced information systems for decision support as well as national emergency management systems is discussed in an attempt to optimize their use in an integrated information network

  15. Third International Conference on Nuclear Power Plant Life Management. Proceedings of an International Conference

    evidenced by the number of licence renewals and long term operating permits that have already been granted to those who employ PLiM programmes. Following the earthquake and tsunami in March 2011 that caused the severe accident at the Fukushima Daiichi plant in Japan, the safety of nuclear power globally has been the subject of increased scrutiny. The global fleet of nuclear power plants has been subject to stress tests in an effort to find ways to identify potential issues and then implement lessons learned to provide enhanced safety. The resulting plant upgrades aim to achieve better control over plant operations, deploy technologies that enhance safety system protection, deploy improved severe accident mitigation measures that address a wider range of design basis events and provide strategies that more effectively deploy human resources utilized in plant operations. The aim is to obtain a workforce and the necessary supporting resources that will be capable of controlling a reactor, even under extreme circumstances that take the plant beyond its design basis envelope. In parallel, ageing management programmes are being updated to bring those additional accident mitigating features, systems, subsystems and services, as well as plant defences that may have been adopted in response to the Fukushima driven stress test recommendations under the umbrella of PLiM programmes. The IAEA has organized two previous PLiM conferences. The First International Conference on Nuclear Power Plant Life Management was held in 2002 in Budapest, Hungary, and the second one was held in 2007 in Shanghai, China. Participants at the first and second conferences recognized the importance of PLiM and the benefits of the information exchange achieved in these conferences. Participants thus recommended that another conference be organized within four to five years. The Third International Conference on Nuclear Power Plant Life Management was held in Salt Lake City, United States of America, 14–18

  16. Status and perspectives of fuel developments for fast neutron reactors of 4th generation

    The R and D strategy in France on future reactors gives first priority to developing a new generation of fast neutron nuclear systems and recycling technologies so as to assure a sustainable and environment friendly electricity production in the second half of the 21st century. SFR is the reference option, not only in France but also in Europe. The European strategy considers both the GFR and LFR as alternatives to the SFR. A common concern is to achieve a convincing demonstration of the capability of fuels to attain the ambitious goals set to 4th generation fast neutron systems, especially in terms of performance (uranium conversion, minimization of long life radioactive wastes) and safety. Owing to the important and satisfactory feedback experience built upon oxide fuels, MOX is the reference fuel for the SFR, at least for the start-up of the prototype (ASTRID). The objectives followed for the 4th generation SFR for safety (for example sodium void worth reduction and limited core reactivity excess) and cycle performances (self-sustainable core with a near zero breeding gain, reasonable in- core Pu inventory, MA transmutation) are achievable with an oxide fuel in large power cores (3600 MWt) while implementing adequate design features. Nevertheless, recent calculations show that the use of a dense and cold ceramic fuel might even improve the core performances. Carbide and nitride are candidate fuels to be seriously investigated for SFRs of 4th generation. For the GFR and the LFR, dense fuels are required to achieve self-generation because of the higher fraction of coolant in the core. Carbide and nitride are currently the reference fuels for the GFR and LFR, respectively. Focused on some key design parameters (such as high breeding capability, safety, expected performances of the fuel cycle based on pyro-metallurgical processes), several countries (India, China, Korea, Japan, USA) are considering the metal fuel for the SFR either as a long term reference or as a

    2016-01-01

    In recent years, the keeping of ornamental freshwater animals and plants in garden ponds has been growing in popularity. Water hyacinth (Eichhornia crassipes) is one of the preferred macrophytes seasonally imported mainly from South-eastern Asia throughout the world. This constitutes a secondary introduction inasmuch as the species is native to South America. Although many assemblages of aquatic invertebrates have been described as associated with this plant in the wild, there has been no research focused on their potential introduction via the international plant trade. We examined 216 specimens of water hyacinths imported for ornamental purposes from Indonesia into the Czech Republic. Numerous meio- and macroinvertebrates belonging to at least 39 species were captured. On the total number of individuals, the highest prevalence was of Tubulinea and Rotifera. Most of these were still alive and vital, including a caterpillar of the Indo–Australian invasive moth Spodoptera litura. Water hyacinths are usually placed into outdoor ponds immediately after import, which facilitates the release of non-target alien species. The present paper aims to draw attention to “hitchhikers” associated with the ornamental trade. PMID:27221025

  20. The challenge of introducing HTR plants on to the international power plant market

    The international power plant market today is characterized by high increase in energy consumption for developing countries with limitations of investment capital and low increase in energy consumption for industrialized countries with limitations of additional power plant capacities. As a consequence there is a low demand for large new power stations. This leads to a tendency for small and medium sized power plant units - meeting high environmental standards - for which the total investment volume is low and full load operation of a plant can be realized earlier due to the small block capacity. - For nuclear power plants the High-Temperature-Reactor (HTR)-line with spherical fuel elements and a core structure of graphite is specially suited for this small and medium sized nuclear reactor (SMSNR) capacity. The excellent safety characteristics, the high availability, the low radiation doses for the operation personnel and the environment of the HTR line has been demonstrated by 20 years of operation of the AVR-15 MWe experimental power plant in Juelich F.R.G. and since 1985 by operation of the THTR-300 MWe prototype plant at Hamm-Uentrop F.R.G. Up-dated concepts of the HTR-line are under design for electricity generation (HTR-500), for co-generation of power and heat (HTR-100) and for district heating purposes only (GHR-10). By implementing two HTR projects the Brown Boveri Group is in the position to realize the collected experiences from design, licensing, erection, commissioning and operation for the follow-on projects. This leads to practical and sound technical solutions convenient for existing manufacturing processes, well known materials, standardized components and usual manufacturing tolerances. Specific plant characteristics can be used for advantages in the competition. (author)

  18. Global perspectives on poisonous plants: the 9th international symposium on poisonous plants.

    Molyneux, Russell J; Panter, Kip E; Zhao, Mengli

    2014-07-30

    The 9th International Symposium on Poisonous Plants (ISOPP9) was held July 15-21, 2013, at the Inner Mongolia Agricultural University in Hohhot, Inner Mongolia Autonomous Region of China. The symposium consisted of three days of oral and poster presentations, followed by a tour of the Xilinhot Region of the Mongolian Grasslands, encompassing grazing conditions consisting of desert, grassland, and steppes. This was the first time that an ISOPP meeting has been held in Asia and provided an opportunity for visitors from outside China to become aware of livestock poisonings caused by plant species with which they were previously not familiar while at the same time demonstrating that many of the problems experienced around the world have a common etiology. Presentations focused on botany, veterinary science, toxicology, mechanism of action, and chemistry. As is appropriate for the Journal of Agricultural and Food Chemistry, this cluster of papers consists of selected oral and poster presentations in which the chemistry of the toxins played a significant role. The symposium revealed that there is considerable scope for isolation, structural elucidation, and analysis of the toxins from the numerous poisonous plant species that have been identified in China. It became apparent that there are abundant opportunities for chemists both within China and abroad to collaborate with Chinese scientists working on biological aspects of livestock poisonings.

  2. Probes for 4th generation constituents of dark atoms in Higgs boson studies at the LHC

    Khlopov, M Yu

    2014-01-01

    The nonbaryonic dark matter of the Universe can consist of new stable charged species, bound in heavy neutral "atoms" by ordinary Coulomb interaction. Stable $\\bar U$ (anti-$U$)quarks of 4th generation, bound in stable colorless ($\\bar U \\bar U \\bar U $) clusters, are captured by the primordial helium, produced in Big Bang Nucleosynthesis, thus forming neutral "atoms" of O-helium (OHe), a specific nuclear interacting dark matter that can provide solution for the puzzles of direct dark matter searches. However, the existence of the 4th generation quarks and leptons should influence the production and decay rates of Higgs boson and is ruled out by the experimental results of the Higgs boson searches at the LHC, if the Higgs boson coupling to 4th generation fermions with is not suppressed. Here we argue that the difference between the three known quark-lepton families and the 4th family can naturally lead to suppression of this coupling, relating the accelerator test for such a composite dark matter scenario to ...

  11. MSSM4G: Reviving Bino Dark Matter with Vector-like 4th Generation Particles

    Abdullah, Mohammad

    2016-01-01

    We supplement the minimal supersymmetric standard model (MSSM) with vector-like copies of standard model particles. Such 4th generation particles can raise the Higgs boson mass to the observed value without requiring very heavy superpartners, improving naturalness and the prospects for discovering supersymmetry at the LHC. Here we show that these new particles are also motivated cosmologically: in the MSSM, pure Bino dark matter typically overcloses the Universe, but 4th generation particles open up new annihilation channels, allowing Binos to have the correct thermal relic density without resonances or co-annihilation. We show that this can be done in a sizable region of parameter space while preserving gauge coupling unification and satisfying constraints from collider, Higgs, precision electroweak, and flavor physics.

  12. Nuclear Power Plant Life Management. Proceedings of An International Symposium

    The original design life of a nuclear power plant (NPP) is commonly around 30-40 years, depending on manufacture and type. However, the actual operational life may be shorter, or longer, based on many factors. Plant life management (PLiM) is a methodology that is appropriate for any length of plant operational life. The proceedings of this symposium reflect the growing interest of Member States in this topic and summarize the conclusions of six major programmatic sessions: approaches to plant life management; economics; ageing management and related operational programmes; system, structure and component design modification, modernization, refurbishment and replacement; managerial issues; and regulatory issues. This publication provides operators and regulators with a comprehensive overview of the state of the science and technology involved in the main issues concerning safe, long term operation, ageing management and the basic economic aspects of plant life management for the nuclear power industry.

    2008-01-01

    Cartesian tensor basis have been widely used to approximate spherical functions. In Medical Imaging, tensors of various orders have been used to model the diffusivity function in Diffusion-weighted MRI data sets. However, it is known that the peaks of the diffusivity do not correspond to orientations of the underlying fibers and hence the displacement probability profiles should be employed instead. In this paper, we present a novel representation of the probability profile by a 4th order ten...

    1995-12-31

    Since the 14th Conference in Amsterdam in 1991, progress in plant hormone research and developmental plant biology has been truly astonishing. The five ``classical`` plant hormones, auxin, gibberellin, cytokinin, ethylene, and abscisic acid, have been joined by a number of new signal molecules, e.g., systemin, jasmonic acid, salicylic acid, whose biosynthesis and functions are being understood in ever greater detail. Molecular genetics has opened new vistas in an understanding of transduction pathways that regulate developmental processes in response to hormonal and environmental signals. The program of the 15th Conference includes accounts of this progress and brings together scientists whose work focuses on physiological, biochemical, and chemical aspects of plant growth regulation. This volume contains the abstracts of papers presented at this conference.

    In recent years, the keeping of ornamental freshwater animals and plants in garden ponds has been growing in popularity. Water hyacinth (Eichhornia crassipes) is one of the preferred macrophytes seasonally imported mainly from South-eastern Asia throughout the world. This constitutes a secondary introduction inasmuch as the species is native to South America. Although many assemblages of aquatic invertebrates have been described as associated with this plant in the wild, there has been no res...

    Caldwell, Martyn M.; Robberecht, Ronald; Flint, Stephan D.

    1983-01-01

    Wavelength-selective absorption of solar radiation within plant leaves allows penetration of visible radiation to the chloroplats, while removing much of the damaging ultraviolet-B radiation. Flavonoids are important in this wavelength-selective absorption. Induction of flavonoid synthesis by solar radiation, and specifically by UV-B radiation, is discussed as this relates to the potential acclimation of plants to enhanced solar UV-B radiation that would result from stratospheric ozone reduct...

  12. Method and application for internal flooding deterministic safety assessment of nuclear power plant

    In order to ensure the safety functions of nuclear power plants in case of internal flooding, it is necessary to consider protection against internal flooding in nuclear power plant design and evaluate the consequence to verify that the target of internal flooding protection can be achieved. According to the study on internal flooding protection purposes, requirements and protection measures, assumptions, methods and steps of internal flooding deterministic safety assessment were sought and presented. Based on a boric acid transportation room and reactor cavity and spent fuel pool cooling and treatment (PTR) pump room of 1000 MWe nuclear power plant, the method was applied and verified. The analysis result shows that the boric acid transportation room doesn't need any protections, but the PTR pump room needs to take drain measures in order to perform the nuclear safety functions.

  13. Internal aeration development and the zonation of plants in wetlands

    Sorrell, Brian Keith

    Permanent and indefinite survival of plants in flooded soils depends primarily on adaptations that increase the supply of oxygen to tissues in anoxic soil and water, usually associated with features such as (i) increased tissue porosity, (ii) changes in tissue permeability to gases, and (iii...... support many species which have root aeration adaptations but are otherwise unspecialised for aquatic life. Permanent standing water is a much greater challenge for plants, and survival here is restricted to species with special adaptations to their oxygen transport physiology such as the development...... differing in flooding tolerance. Maintaining species diversity in managed wetlands therefore involves hydrological conditions suitable for a variety of plants that differ in their flooding tolerance. The shallowest areas of wetlands, in which soils are waterlogged but there is little standing water, can...

  15. Internal emergency organization in the Beznau nuclear power plant

    The successful mastering of every emergency situation is based on the strict adherence to frequently reviewed emergency instruction and practice on simulators. This is the primary duty of all plant employees. In addition, executive bodies are necessary. The highest authority in the emergency organization is the emergency staff. Under the leadership of the plant manager, this staff consists of all department heads and several specialists. Outside normal working hours, it can be expected of the emergency staff that it is fully functional within, at most, one hour. Until the emergency staff can take over, the on-duty engineer leads emergency procedures. Several other different teams are responsible to the emergency staff. There are five emergency teams: off-duty plant employees; fire fighters; radiation defence; first-aid; plant guards. Then there is the technical support center (TSC). The responsibilities of the TSC are: giving technical advise to the emergency staff; working out different options for fighting the emergency; checking up on special methods; communication with the reactor manufacturer for additional support. 1 fig

  16. Creating an agricultural world order: regional plant protection problems and international phytopathology, 1878-1939.

    Castonguay, Stéphane

    2010-01-01

    Beginning in 1878 with the International Phylloxera Convention of Berne, international conventions have sought to relieve national agricultural industries from two specific burdens. First, by defining phytosanitary practices to be enforced by national plant protection services, these conventions attempted to prevent the introduction of plant diseases and pests into national territories from which they were previously absent. Second, by standardizing these practices - especially through the design of a unique certificate of inspection - the conventions attempted to eliminate barriers such as quarantines affection international agricultural trade. The succession of phytopathological conventions seemed to epitomize the coalescence of an international community against agricultural pests. What actually coalesced was bio-geopolitics wherein plant pathologists and economic entomologists from North America and the British Empire questioned the so-called internationality of the environmental and economic specificities of continental European agriculture, embodied in "international" conventions. Although an international phenomenon, the dissemination of agricultural pests provided opportunities for cooperation on a strictly regional albeit transnational basis that pitted bio-geopolitical spaces against each other. This article retraces the formation of these spaces by analyzing the deliberations of committees and congresses that gathered to define an international agricultural order based on the means to prevent the spread of plant diseases and pests.

  17. Can astronomy enhance UNESCO World Heritage recognition? The paradigm of 4th Dynasty Egyptian pyramids

    Belmonte, Juan Antonio

    2015-08-01

    The pyramids of Egypt, notably those of the 4th Dinasty as Giza, have always be considered an unmistikable part of human world heritage as the only surviving wonders of the Ancient World. Their majesty, technical hability and innovative character have always beeen considered as representative of ancient Egyptian ingenuity. However, past and present fringe theories about the pyramids and astronomy have always polluted the role of our discipline in the design, construction and symbolism of these impressive monuments. This is indeed unfear. Fortunately, things have started to change in the last couple of decades and now astronomy is interpreted as a neccessary tool for the correct interpretation of the astral eschatology present in the 5th and 6th Dynasty Texts of the Pyramids. Although the pyramid complexes of the 4th Dynasty are mute, there is however recent research showing that a strong astral symbolism could be hidden in many aspects of the complex architecture and in the design of these exceptional monuments. This idea comes from several hints obtained not only from planning and construction, but also from epigraphy and the analysis of celestial and local landscapes. Chronology also plays a most relevant role on this. The pyramid complexes of the 4th Dynasty at Meidum, Dahshur, Giza and Abu Rowash -- all of which enjoy UNESCO World Heritage recognition -- willl be scrutinized. As a consequence, we will show how astronomy can certainly enhance the face value of these extraordinary monuments as a definitive proof of the ancient Egyptian quest for Ma'at, i.e. their perennial obsesion for Cosmic Order.

    The Chinese pro-democracy movement crushed by the People’s Liberation Army on 4 June 1989 was preceded by many protests by intellectuals. The crackdown deprived the democrats of their protectors in the Party, and forced them to change strategies. Unable to organise large-scale demonstrations, dissidents launched petitions demanding respect for human rights and reversal of the official verdict on June 4th. They were joined by the Tiananmen Mothers, who became a new force in the pro-democracy m...

  2. 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.

  3. The Nabataean Age (4th century BC - 1st century AD)

    Augé, Christian

    2014-01-01

    We do not know the exact origins of the Nabataeans; they are a nomadic people from Arabia who settled in present-day Jordan between the 6th and 4th centuries BC. In 312, they already occupied the former lands of the Edomites, between Wadi al-Hasa (Zered) and the Gulf of Aqaba (Aila), and resisted Antigone, one of Alexander’s successors. The control of trade routes ensured their wealth. During the Hellenistic period, Petra, a storage area and shelter, became the capital of a kingdom that exten...

  4. Generalized effective potential in nonlinear theories of the 4-th order

    By means of the Legendre transformations in the framework of nonlinear theories of the 4-th order a generalized effective potential GITA(phi, G, H, S) is constructed. It depends on PHI, a possible expectation value of the quantum field; on G, H, possible expectation values of the 2- a.nd 3-point connected Green functions and on S= a possible expectation value of the classical action. The expansion for the functional GITA(phi, G, H, S) is obtained, which is similar to the loop expansion for the effective action GITA(phi)

The two successive phases of the quality management are presented. The difficulties and improvment possibilities are discussed

  7. The role of the International Atomic Energy Agency safety missions in upgrading plant safety at Krsko nuclear power plant

    The role of the International Atomic Energy Agency (IAEA) safety missions in upgrading plant safety at Krsko NPP is defined. Krsko NPP is a two loop PWR plant designed by Westinghouse. The safety missions, following the invitation of the Yugoslavian Government, visited the plant on numerous occasions from the early construction phase to full power operation. The purpose of inviting the missions was to provide a second independent international viewpoint on various subjects related to safety features of plant design, equipment characteristics, utility organization during contruction and operation, quality control and quality assurance programmes and plant commissioning. The main activities of the IAEA missions during plant construction were related to the analysis of the preliminary and final safety analysis reports, especially where specific site conditions deviate from the standard United States Regulatory Guides (for example site meteorology and related environmental dose calculations) or where new design features have been introduced (such as 16x16 fuel design or emergency core cooling systems for two loop plants). Special consideration has been given to plant safety systems upgrading, particularly since the Three Mile Island accident. Mission advice on this subject was very valuable because it has provided the utility and licensing body with independent engineering judgements on the merit of particular hardware changes. In addition, the missions spent considerable time in analysing the role, functions and training of regulatory body personnel, the functions of utility organizations, especially in the areas related to safety (function of the quality assurance department and future organization for plant operation). Following the start of plant commercial operation the IAEA was invited to send the Operational Safety Review Team and the Assessment of Safety Significant Events Team. The paper describes the outcome of these missions. Finally, some general comments

  9. The challenge of introducing high-temperature reactor plants onto the international power plant market

    Growth of world population increases energy demand until the year 2000 and afterwards. Electricity growth rates in industrialized nations are lower after the oil price escalation in 1973 and 1979, and in developing countries grid sizes are often too small for the operation of large LWR plants. This indicates a potential for small and medium-sized power reactors such as the HTR-100 and the HTR-500. These plants can compete with coal fired plants of comparable size. An HTR-500 is even competitive, considering the electricity generating cost of large LWR plants. The special advantages of HTR plants in the small and medium-capacity range are discussed. (orig.)

  10. The 2002 activities and the 4th workshop of the human resources development project in FNCA

    In 1999, the Project for Human Resources Development (HRD Project) was initiated as defined in the framework of the Forum for Nuclear Cooperation in Asia (FNCA), organized by the Atomic Energy Commission of Japan. The objective of the HRD Project is to solidify the foundation of technologies for nuclear development and utilization in Asia by promoting human resources development in Asian countries. In the Project there are two kinds of activity; In-workshop activity and Outside-of-workshop activity. The 4th Workshop on HRD Project was held on october 8-10, 2002, in Batangas, the Philippines. The Workshop was sponsored by the Department of Science and Technology (DOST) of the Philippines and the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan. The Philippine Nuclear Research Institute (PNRI) and the Japan Atomic Energy Research Institute (JAERI) acted as the hosts. Participating countries were China, Indonesia, Republic of Korea, Japan, Malaysia, the Phillippines, Thailand, and Vietnam. This report consists of presentation papers and materials at the 4th workshop as In-Workshop Activity, a review document of HRD Project for the 5th Coordinators Meeting of FNCA at Tokyo on March, 2003, a letter of proposal from the Project Leader of Japan to the Project Leaders of the participating countries, and training materials of participating countries as Outside-Workshop Activity.

  11. Fast and Analytical EAP Approximation from a 4th-Order Tensor

    Aurobrata Ghosh

    2012-01-01

    Full Text Available Generalized diffusion tensor imaging (GDTI was developed to model complex apparent diffusivity coefficient (ADC using higher-order tensors (HOTs and to overcome the inherent single-peak shortcoming of DTI. However, the geometry of a complex ADC profile does not correspond to the underlying structure of fibers. This tissue geometry can be inferred from the shape of the ensemble average propagator (EAP. Though interesting methods for estimating a positive ADC using 4th-order diffusion tensors were developed, GDTI in general was overtaken by other approaches, for example, the orientation distribution function (ODF, since it is considerably difficult to recuperate the EAP from a HOT model of the ADC in GDTI. In this paper, we present a novel closed-form approximation of the EAP using Hermite polynomials from a modified HOT model of the original GDTI-ADC. Since the solution is analytical, it is fast, differentiable, and the approximation converges well to the true EAP. This method also makes the effort of computing a positive ADC worthwhile, since now both the ADC and the EAP can be used and have closed forms. We demonstrate our approach with 4th-order tensors on synthetic data and in vivo human data.

  12. Ageing Management for Nuclear Power Plants: International Generic Ageing Lessons Learned (IGALL)

    This publication provides a common internationally agreed basis on what constitutes an acceptable ageing management programme, as well as a knowledge base on ageing management for the design of new plants, design and safety reviews, and aims to serve as a roadmap to available information on ageing management. It addresses ageing management of passive and active structures and components for water moderated reactors that can have an impact, directly or indirectly, on the safe operation of the plant and that are susceptible to ageing degradation. The information provided is relevant for plants under normal operation, for plants considering long term operation, as well as for new plants including new designs. It underlines that ageing management should be implemented from the start of operation of nuclear power plants and that adequate provisions to facilitate effective ageing management should be made during the plant design, construction commissioning, operation, and decommissioning

    Hoelscher Deanna M

    2008-05-01

    Full Text Available Abstract Introduction Although per capita crime has generally fallen over the period which coincides with the obesity epidemic, it has not fallen uniformly across communities. It also has not fallen enough to allay fears on the part of parents. Over the past 30 years, technological changes have made the indoor alternatives to playing outside, where children are more vulnerable to criminal activity, more enjoyable (cable TV, video games, and the internet and comfortable (the spread of air conditioning to low income neighborhoods. We determined whether indoor sedentary behavior patterns are associated with community crime statistics. 4th graders in the U.S. are typically 9 or 10 years old. Methods We used data from the 2004–2005 Texas School Physical Activity and Nutrition (SPAN survey linked with U.S. Department of Justice, Office of Justice Programs, Bureau of Justice Statistics data for the years 2000 through 2005 and Texas State data on sexual offenders. The probability-based sample included a total of 7,907 children in grade four. Multistage probability sampling weights were used. The dependent variables included were hours of TV watching, video game playing, computer use and total indoor sedentary behavior after school. Incremental Relative Rates were computed for community crime rates including robberies, all violent crimes, murders, assaults, property crimes, rapes, burglaries, larcenies and motor vehicle thefts as well as for sexual offenders living in the neighborhood. The neighborhood refers to the areas where the students at each school live. In the case of sexual offenders, sexual offenders per capita are estimated using the per capita rate in the zip code of the school attended; all other crime statistics are estimated by the crimes per capita in the police department jurisdiction covering the school attended. After controlling for sex, age, and African-American and Hispanic, cross-sectional associations were determined using

  15. Second international symposium on nuclear power plant life management. Book of extended synopses

    and transferred throughout a plant's life. The IAEA recognizes the safety and cost considerations of extended nuclear power operation and has organized a major international symposium on the newest developments, best practices and issues surrounding the extended operation of older plants. The IAEA also recognizes that new plants will be operated for extended periods of time and that efficient PLiM is important for maintaining and increasing nuclear power plant operational safety, availability and reliability. The IAEA organized the First International Symposium on Nuclear Power Plant Life Management in Budapest, Hungary, from 4 to 8 November 2002. Participants at that symposium placed a high value on information exchange during the symposium and recommended that another symposium be organized within the next four to five years. Therefore, the IAEA organized the Second International Symposium on Nuclear Power Plant Life Management. This symposium focused on topical issues affecting nuclear power PLiM and thus is expected to be of particular interest to managers and technical managers involved in the operation or regulation of nuclear power plants and research reactors. The objectives of the second international symposium on PLiM are to: Emphasize the role of PLiM programmes in assuring safe and reliable nuclear power plant operation; Provide a forum for information exchange on national and international policies, regulatory practices and safety culture and to demonstrate strategies, including application in an ageing management and PLiM programme; Provide key elements and good practices related to the safety aspects of ageing, ageing management and long term operation; Identify the progress on ageing management and PLiM processes since the first international symposium; Help Member States further develop their PLiM programmes based on the newest technology available

  16. International Thermonuclear Experimental Reactor (ITER) plant layout and site services

    The ITER site has not been determined at this time. Nevertheless, to develop a construction plan and a cost estimate, it is necessary to have a detailed layout of the buildings, structures, and outdoor equipment integrated with the balance of plant service systems prototypical of large fusion power plants. These services include electric power for magnet feeds and plasma heating systems, cryogenic and conventional cooling systems, compressed air, gas supplies, de-mineralized water, steam, and drainage. Nuclear grade facilities are provided to handle tritium fuel and activated waste, as well as to prevent radioactive exposure of either the workers or the public. To avoid interference between services of different types and for efficient arrangement of buildings, structures, and equipment within the site area, a plan was developed which segregated different classes of services to four quadrants surrounding the tokamak building, placed at the approximate geographic center of the site. Location of the twenty-seven buildings on the generic site was selected to meet all design requirements at minimum total project cost. A similar approach has been used to determine the location of services above, at, and below grade. The generic site plan can be adapted to the site selected for ITER without significant changes to the buildings or equipment. Some rearrangements may be required by site topography resulting primarily in changes to the length of services that link the buildings and equipment. (author)

  17. Meeting report: 4th ISIRV antiviral group conference: Novel antiviral therapies for influenza and other respiratory viruses.

    McKimm-Breschkin, Jennifer L; Fry, Alicia M

    2016-05-01

    The International Society for Influenza and other Respiratory Virus Diseases (isirv) held its 4th Antiviral Group Conference at the University of Texas on 2-4 June, 2015. With emerging resistance to the drugs currently licensed for treatment and prophylaxis of influenza viruses, primarily the neuraminidase inhibitor oseltamivir phosphate (Tamiflu) and the M2 inhibitors amantadine and rimantadine, and the lack of effective interventions against other respiratory viruses, the 3-day programme focused on the discovery and development of inhibitors of several virus targets and key host cell factors involved in virus replication or mediating the inflammatory response. Virus targets included the influenza haemagglutinin, neuraminidase and M2 proteins, and both the respiratory syncytial virus and influenza polymerases and nucleoproteins. Therapies for rhinoviruses and MERS and SARS coronaviruses were also discussed. With the emerging development of monoclonal antibodies as therapeutics, the potential implications of antibody-dependent enhancement of disease were also addressed. Topics covered all aspects from structural and molecular biology to preclinical and clinical studies. The importance of suitable clinical trial endpoints and regulatory issues were also discussed from the perspectives of both industry and government. This meeting summary provides an overview, not only for the conference participants, but also for those interested in the current status of antivirals for respiratory viruses. PMID:26872862

    Adler, Mark; Mangold, Karen; Trainor, Jennifer

    2016-01-01

    The transition from medical student to intern is a challenging process characterized by a steep learning curve. Focused courses targeting skills necessary for success as a resident have increased self-perceived preparedness, confidence, and medical knowledge. Our aim was to create a brief educational intervention for 4th-year medical students entering pediatric, family practice, and medicine/pediatric residencies to target skills necessary for an internship. The curriculum used a combination of didactic presentations, small group discussions, role-playing, facilitated debriefing, and simulation-based education. Participants completed an objective structured clinical exam requiring synthesis and application of multiple boot camp elements before and after the elective. Participants completed anonymous surveys assessing self-perceived preparedness for an internship, overall and in regards to specific skills, before the elective and after the course. Participants were asked to provide feedback about the course. Using checklists to assess performance, students showed an improvement in performing infant lumbar punctures (47.2% vs 77.0%; p plan to implement in internship,” and “I think all students should participate in a similar experience.” When asked to assess the usefulness of individual modules, all except order writing received a mean Likert score > 4. A focused boot camp addressing key knowledge and skills required for pediatric-related residencies was well received and led to improved performance of targeted skills and increased self-reported preparedness in many targeted domains.

  19. Third international congress of plant molecular biology: Molecular biology of plant growth and development

    Hallick, R.B. [ed.

    1995-02-01

    The Congress was held October 6-11, 1991 in Tucson with approximately 3000 scientists attending and over 300 oral presentations and 1800 posters. Plant molecular biology is one of the most rapidly developing areas of the biological sciences. Recent advances in the ability to isolate genes, to study their expression, and to create transgenic plants have had a major impact on our understanding of the many fundamental plant processes. In addition, new approaches have been created to improve plants for agricultural purposes. This is a book of presentation and posters from the conference.

  1. The International Plant Protection Convention, living modified organisms and pest risk analysis

    As technology improves, the types of organisms that are being transformed using the techniques of modern biotechnology are steadily increasing. Concurrently, the movement of these organisms across borders in trade or for other purposes has also increased. Many countries, in particular developing countries, require guidance on how to assess the potential risks that may be associated with transgenic organisms, and how these organisms can or should be regulated. The International Plant Protection Convention produces international standards for phytosanitary measures that can provide countries with guidance on how to conduct pest risk analysis, and how to implement measures to protect plant life or health within their territories. This paper will provide an overview of: - the International Plant Protection Convention and other international instruments relevant to the transboundary movement of transgenic organisms; - the legal basis for risk analysis for transgenic organisms in international instruments; - procedures for pest risk analysis under the IPPC; - the application of international standards for phytosanitary measures (including the pest risk analysis standards) for assessing and managing plant pest risks of LMOs; and - future activities of the IPPC with regard to LMOs.

  2. Decommissioning nuclear power plants: a case for internal funding

    Historically, utilities have exercised sole responsibility for reinvesting capital funds collected from ratepayers. Capital provided by ratepayers, whether for recovery of invested capital or for removal costs, reduces the magnitude of future borrowings - dollar for dollar. If regulatory commissions require utilities to place these collections in separate, inaccessible investment accounts (as in external funding methods), then utilities will be denied the use of these funds. Ratepayers, in turn, will be denied both their usual interest credit and the cost-saving benefits afforded by utilities having readily accessible cash to use instead of having to resort to borrowing. Such benefits can be attained only through internal-funding methods that keep rate payer contributions under unrestricted utility control. While state regulatory commissions currently favor external funding for financial assurance, the author feels the extra cost to ratepayers and the utilities is too high a price to pay

    The use of environmental sampling is a major component of the improvements of International Atomic Energy Agency safeguards being carried out under Program 93+2. Nonradioactive noble gas isotopic measurements in the effluent stream of large reprocessing facilities may provide useful confirmatory information on the burnup and reactor type of the spent fuel undergoing reprocessing. The authors have taken and analyzed stack samples at an operating facility. The data show clear fission signals. The authors are currently applying a maximum-likelihood estimation procedure to determine the fuel burnup from these data. They anticipate that the general features involved in the table noble gas problem--selection of appropriate signals, measurement of those signals under realistic conditions, and inverse calculation of parameters of interest from the environmental data--will be present in all environmental sampling problems. These methods should therefore be widely applicable.

  9. Ignalina plant licensing process, international co-operation and assistance

    The challenge for Lithuania as a country with regained independence was to perform a licensing review in a way never done before in the country and in a time schedule that was extremely short. The work included establishing of the licensing base, strengthening the regulatory authority and organising the technical support, establish and implement a safety improvement program, production of the safety case and review of the safety case, and to derive a conclusion regarding whether to issue a licence or not. This was to be done together with other tasks, such as implementation of modifications included in the safety improvement programme at Ignalina, implementation of a new storage for spent fuel and, most important of all, to manage the operational safety at the plant. The achievements are impressive seen in view of the point of start and in view of the time and resources that have been available. Lithuania has put forward a unique safety documentation of an RBMK reactor and presented an in-depth safety evaluation in full openness to Western experts, giving the unique possibility to compare the safety of the Ignalina reactors to Western standards. The co-operation that has been established between Lithuania and Western experts through different assistance programmes is of outmost value, for all involved parties. Co-operation should continue as one element of the challenges for the future

  10. Internal experience methodology at the Almaraz nuclear power plant

    It is widely accepted in risk analyses that serious accidents can frequently occur as a result of the combination of a number of more or less trivial incidents aggravated by human errors, or by other non-related failures. This is why a permanent concern at the Central Nuclear de Almaraz since the early days of operation has been to pay special attention to the correction of insignificant failures in order to predict and prevent other, more important, failures. However, only last year, with experience gained from the Trip Reduction Programme, was the Programme for the Application of Internal Experience (PAIE) initiated with a specific methodology, which, in turn, consists of the following phases: the communications process and scope of the PAIE; the screening process; investigation and analysis of direct and root causes; corrective actions; dissemination of the lessons learned. This Programme also provides for the correction of human failures, but the methodology differs from the above in that the first two phases are accomplished through quality circles. (author). 5 figs

  13. FAST DISPLACEMENT PROBABILITY PROFILE APPROXIMATION FROM HARDI USING 4TH-ORDER TENSORS.

    Barmpoutis, Angelos; Vemuri, Baba C; Forder, John R

    2008-05-14

    Cartesian tensor basis have been widely used to approximate spherical functions. In Medical Imaging, tensors of various orders have been used to model the diffusivity function in Diffusion-weighted MRI data sets. However, it is known that the peaks of the diffusivity do not correspond to orientations of the underlying fibers and hence the displacement probability profiles should be employed instead. In this paper, we present a novel representation of the probability profile by a 4(th) order tensor, which is a smooth spherical function that can approximate single-fibers as well as multiple-fiber structures. We also present a method for efficiently estimating the unknown tensor coefficients of the probability profile directly from a given high-angular resolution diffusion-weighted (HARDI) data set. The accuracy of our model is validated by experiments on synthetic and real HARDI datasets from a fixed rat spinal cord. PMID:20046536

    Full Text Available This study investigates teachers’ views on primary school English language teaching curriculum for the 4th grade. For this aim, objectives, content, activities, materials and equipment and assessment which are the basic components of the curriculum are taken as the criterion. Besides this, the study investigates teachers’ level of information about the curriculum, the difficulties that were experienced by teachers in implementing the curriculum, the strengths and weaknesses of the curriculum and teachers’ suggestions for improving the curriculum. This is a qualitative research and employs interview techniques. Data were collected through interviews of 15 primary school English teachers who taught 4th grade students at state schools. In the data analysis procedure descriptive analysis techniques were applied.The results of the research indicated that the participants had negative views about some aspects of the curriculum due to challenges that they encountered during the implementation. It was determined that teachers thought that the level they informed about the program was not sufficient. Teachers emphasized that crowded classrooms, lack of sources and supplementary materials caused problems in implementing the curriculum. It was pointed out that the strongest feature of the curriculum was that it made the students active during the learning process. The weakest feature of the curriculum was that it was overloaded and time allocated to the curriculum was not sufficient. In order to make the curriculum more efficient teachers suggested that more qualified learning materials should be prepared, alloted time for the lesson should be increased, the number of students in the classroom should be reduced and assessment tools should be provided for the teachers.

    Health professionals and policymakers are asking educators to place more emphasis on food and nutrition education. Integrating these topics into science curricula using hand-on, food-based activities may strengthen students' understanding of science concepts. The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. Previous studies have shown that students experiencing the FoodMASTER curriculum were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations. The purpose of this study was to: 1) assess 4(th) graders food-related multidisciplinary science knowledge, and 2) compare gains in food-related science knowledge after implementation of an integrated, food-based curriculum. During the 2009-2010 school year, FoodMASTER researchers implemented a hands-on, food-based intermediate curriculum in eighteen 4(th) grade classrooms in Ohio (n=9) and North Carolina (n=9). Sixteen classrooms in Ohio (n=8) and North Carolina (n=8), following their standard science curricula, served as comparison classrooms. Students completed a researcher-developed science knowledge exam, consisting of 13 multiple-choice questions administered pre- and post-test. Only subjects with pre- and post-test scores were entered into the sample (Intervention n=343; Control n=237). No significant differences were observed between groups at pre-test. At post-test, the intervention group scored (9.95±2.00) significantly higher (p=.000) than the control group (8.84±2.37) on a 13-point scale. These findings suggest the FoodMASTER intermediate curriculum is more effective than a standard science curriculum in increasing students' multidisciplinary science knowledge related to food.

    Surveillance testing for reactor vessel materials is performed in order to evaluate the irradiation embrittlement due to neutrons during operation and set the condition of safe operation of nuclear reactor. The 4th surveillance testing was performed completely by Korea Atomic Energy Research Institute at Taejeon after the capsule was transported from Kori site including its removal from reactor. Fast neutron fluences for capsules were calculated and various testing including mechanical and chemistry analysis were performed in order to evaluate the integrity of Kori unit 3 reactor vessel during the operation until life time. The evaluation results are as follows; Fast neutron fluences for capsules U, V, X and W are 4.983E+18, 1.641E+19, 3.158E+19, and 4.469E+19n/cm{sup 2}, respectively. The bias factor, the ratio of calculation/measurement, was 0.840 for the 1st through 4th testing and the calculational uncertainty, 12% satisfied the requirement of USNRC Reg.Guide DG-1053, 20%. The best estimated neutron fluence for reactor vessel inside surface was 1.362E+19n/cm{sup 2} based on the end of 12th fuel cycle and it was predicted that the fluences of vessel inside surface at 32, 40, 48 and 56EFPY would reach 3.481E+19, 4.209E+19, 5.144E+19 and 5.974E+19n/cm{sup 2} based on the current calculation. The result through this analysis for Kori unit 3 showed that there would be no problem for the pressurized thermal shock(PTS) during the operation until design life. 48 refs., 35 figs., 41 tabs.

  20. Internal combustion engine combined heat and power plants: Case study of the University of Perugia power plant

    A performance and economic analysis of an existing combined heat and power plant with an internal combustion engine and district heating for the Faculty of Engineering of the University of Perugia is presented. Results of the first 15 months of operation are shown and discussed with reference to daily performance of the combined heat and power plant, which shows how electric efficiency is only slightly affected by ambient temperature. A comparison of evaluation indexes for cogeneration plants is made with particular attention to the energy index (EI) which is used by Italian legislation as an evaluation parameter to decide if a combined heat and power plant can have access to financial benefits.A cost-benefits analysis based on the first year of operation was made to decide eventual changes in heat and power management, in order to reduce pay-back period and increase the internal rate of return of the investment.

  1. Potential improvements in materials accounting for an internationally safeguarded fuels reprocessing plant

    The effectiveness of improved materials accounting was evaluated using computer modeling, simulation, and analysis techniques for two model reprocessing plants. One plant, sized to 210 MTHM/yr, represents the small plants currently under international safeguards and the other, sized to 1500 MTHM/yr, represents the large plants expected in the future. The study indicates that conventional accounting may meet IAEA goal quantities and detection times for low-enriched uranium in these facilities. Dynamic materials accounting can meet the IAEA goal for detecting abrupt (1 to 3 wk) diversion of 8 kg of plutonium. Current materials accounting techniques probably cannot meet the protracted diversion goal of detecting 8 kg for plutonium in 1 yr. Facility design features that can improve the effectiveness of materials accounting in future plants are discussed

  3. International outage coding system for nuclear power plants. Results of a co-ordinated research project

    The experience obtained in each individual plant constitutes the most relevant source of information for improving its performance. However, experience of the level of the utility, country and worldwide is also extremely valuable, because there are limitations to what can be learned from in-house experience. But learning from the experience of others is admittedly difficult, if the information is not harmonized. Therefore, such systems should be standardized and applicable to all types of reactors satisfying the needs of the broad set of nuclear power plant operators worldwide and allowing experience to be shared internationally. To cope with the considerable amount of information gathered from nuclear power plants worldwide, it is necessary to codify the information facilitating the identification of causes of outages, systems or component failures. Therefore, the IAEA established a sponsored Co-ordinated Research Project (CRP) on the International Outage Coding System to develop a general, internationally applicable system of coding nuclear power plant outages, providing worldwide nuclear utilities with a standardized tool for reporting outage information. This TECDOC summarizes the results of this CRP and provides information for transformation of the historical outage data into the new coding system, taking into consideration the existing systems for coding nuclear power plant events (WANO, IAEA-IRS and IAEA PRIS) but avoiding duplication of efforts to the maximum possible extent

  4. Minimal Internal Radiation Exposure in Residents Living South of the Fukushima Daiichi Nuclear Power Plant Disaster.

    Full Text Available Following the Fukushima nuclear power plant disaster, assessment of internal radiation exposure was indispensable to predict radiation-related health threats to residents of neighboring areas. Although many evaluations of internal radiation in residents living north and west of the crippled Fukushima nuclear power plant are available, there is little information on residents living in areas south of the plant, which were similarly affected by radio-contamination from the disaster. To assess the internal radio-contamination in residents living in affected areas to the south of the plant or who were evacuated into Iwaki city, a whole body counter (WBC screening program of internal radio-contamination was performed on visitors to the Jyoban hospital in Iwaki city, which experienced less contamination than southern areas adjacent to the nuclear plant. The study included 9,206 volunteer subjects, of whom 6,446 were schoolchildren aged 4-15 years. Measurements began one year after the incident and were carried out over the course of two years. Early in the screening period only two schoolchildren showed Cs-137 levels that were over the detection limit (250 Bq/body, although their Cs-134 levels were below the detection limit (220 Bq/body. Among the 2,760 adults tested, 35 (1.3% had detectable internal radio-contamination, but only for Cs-137 (range: 250 Bq/body to 859 Bq/body, and not Cs-134. Of these 35 subjects, nearly all (34/35 showed elevated Cs-137 levels only during the first year of the screening. With the exception of potassium 40, no other radionuclides were detected during the screening period.

    This report describes various factors on the IASCC of reactor internals in terms of fluence, stress, water chemistries and materials. Materials of each components of Korean nuclear power plants have been surveyed. A technical report for a management of reactor internals issued by EPRI was reviewed for a selection of most susceptible area among many components. Baffle former bolts are considered to be the most susceptible parts due to high irradiation level(fluence) and high tensile stress. Neutron fluence of Kori-1 and Kori-2 was calculated based on fuel exchange history, fuel performance and plant operation history. This report will be used for more advanced inspection and maintenance guidelines development by supplying inspection intervals and components (most susceptible regions) for the long term operation plants

The report on Mitigation attempted to compile the latest scientific knowledge relating to low-carbon emitting technologies; assessed their costs and potentials for greenhouse gas (GHG) emission avoidance; evaluated their long term prospects out to 2100 for stabilising atmospheric GHGs; provided a detailed list of policy options; and discussed the opportunities for sustainable development and equity linked with GHG abatement. Over the 3 year writing and review process, the author of this paper was the co-ordinating lead author of the writing team for the Working Group III chapter on Energy Supply. Of the 13 chapters, this one received the greatest attention with over 5000 review comments that were each responded to, and with the sections on nuclear and renewable energy receiving a major share of them. Since the 3rd Assessment Report (TAR) was published in 2001, the over-arching message now being delivered by Working Group III is a stronger but positive one: Action is required. The situation is urgent - but not beyond repair. Many energy

  8. Nuclear power plant control and instrumentation 1982. Proceedings of an international symposium on nuclear power plant control and instrumentation

    Ever increasing demands for nuclear power plant safety and availability imply a need for the introduction of modern measurement and control methods, together with data processing techniques based on the latest advances in electronic components, transducers and computers. Nuclear power plant control and instrumentation is therefore an extremely rapidly developing field. The present symposium, held in Munich, FR Germany, was prepared with the help of the IAEA International Working Group on Nuclear Power Plant Control and Instrumentation and organized in close co-operation with the Gesellschaft fur Reaktorsicherheit, Federal Republic of Germany. A number of developments were highlighted at the Munich symposium: - The increased use of computers can bring clear advantages and this technique is now proven as a tool for supervising and controlling plant operation. Advanced computerized systems for operator support are being developed on a large scale in many countries. The progress in this field is quite obvious, especially in disturbance analysis, safety parameter display, plant operator guidance and plant diagnostics. The new trend of introducing computers and microprocessors in protection systems makes it easy to implement 'defence-in-depth' strategies which give better assurance of correct system responses and also prevent unnecessary reactor trips, thus improving plant availability. The introduction of computerized systems for control of reactor power, reactor water level and reactor pressure as well as for reactor start-up and shut-down could improve the reliability and availability of nuclear power plants. The rapid technical development in the area of control and instrumentation makes it necessary to plan for at least one replacement of obsolete equipment in the course of the 30 years lifetime of a nuclear power plant and retrofitting of currently operating reactors with new control systems. Major design improvements and regulatory requirements also require

    The transition from medical student to intern is a challenging process characterized by a steep learning curve. Focused courses targeting skills necessary for success as a resident have increased self-perceived preparedness, confidence, and medical knowledge. Our aim was to create a brief educational intervention for 4th-year medical students entering pediatric, family practice, and medicine/pediatric residencies to target skills necessary for an internship. The curriculum used a combination of didactic presentations, small group discussions, role-playing, facilitated debriefing, and simulation-based education. Participants completed an objective structured clinical exam requiring synthesis and application of multiple boot camp elements before and after the elective. Participants completed anonymous surveys assessing self-perceived preparedness for an internship, overall and in regards to specific skills, before the elective and after the course. Participants were asked to provide feedback about the course. Using checklists to assess performance, students showed an improvement in performing infant lumbar punctures (47.2% vs 77.0%; p skills, except for obtaining consults and interprofessional communication. There was no increase in reported overall preparedness. All participants agreed with the statements, "The facilitators presented the material in an effective manner," "I took away ideas I plan to implement in internship," and "I think all students should participate in a similar experience." When asked to assess the usefulness of individual modules, all except order writing received a mean Likert score > 4. A focused boot camp addressing key knowledge and skills required for pediatric-related residencies was well received and led to improved performance of targeted skills and increased self-reported preparedness in many targeted domains.

    Internal combustion engines (ICEs) have been used in industry and power generation much before they were massively employed for transportation. Their high reliability, excellent power-to-weight ratio, and thermal efficiency have made them a competitive choice as main energy converters in small to medium sized power plants. Process simulators can model ICE powered energy plants with limited depth, due to the highly simplified ICE models used. Usually a better understanding of the global effects of different engine parameters is desirable, since the combustion process within the ICE is typically the main cause of exergy destruction in systems which utilize them. Dedicated commercial ICE simulators have reached such a degree of maturity, that they can adequately model a wide spectrum of phenomena that occur in ICEs. However, ICE simulators are unable to incorporate the remaining of power plant equipment and processes in their models. This paper presents and exploits the integration of an internal combustion engine simulator with a process simulator, so as to evaluate the construction of a fully coupled simulation platform to analyze the performance of ICE-based power plants. A simulation model of an actual cogeneration plant is used as a vehicle for application of the proposed computational methodology. The results show that by manipulating the engine mapping parameters, the overall efficiency of the plant can be improved. (author)

  11. PREFACE: 9th World Congress on Computational Mechanics and 4th Asian Pacific Congress on Computational Mechanics

    2010-07-01

    The use for mathematical models of natural phenomena has underpinned science and engineering for centuries, but until the advent of modern computers and computational methods, the full utility of most of these models remained outside the reach of the engineering communities. Since World War II, advances in computational methods have transformed the way engineering and science is undertaken throughout the world. Today, theories of mechanics of solids and fluids, electromagnetism, heat transfer, plasma physics, and other scientific disciplines are implemented through computational methods in engineering analysis, design, manufacturing, and in studying broad classes of physical phenomena. The discipline concerned with the application of computational methods is now a key area of research, education, and application throughout the world. In the early 1980's, the International Association for Computational Mechanics (IACM) was founded to promote activities related to computational mechanics and has made impressive progress. The most important scientific event of IACM is the World Congress on Computational Mechanics. The first was held in Austin (USA) in 1986 and then in Stuttgart (Germany) in 1990, Chiba (Japan) in 1994, Buenos Aires (Argentina) in 1998, Vienna (Austria) in 2002, Beijing (China) in 2004, Los Angeles (USA) in 2006 and Venice, Italy; in 2008. The 9th World Congress on Computational Mechanics is held in conjunction with the 4th Asian Pacific Congress on Computational Mechanics under the auspices of Australian Association for Computational Mechanics (AACM), Asian Pacific Association for Computational Mechanics (APACM) and International Association for Computational Mechanics (IACM). The 1st Asian Pacific Congress was in Sydney (Australia) in 2001, then in Beijing (China) in 2004 and Kyoto (Japan) in 2007. The WCCM/APCOM 2010 publications consist of a printed book of abstracts given to delegates, along with 247 full length peer reviewed papers published with

  12. Cutting orientations for non-complex parts in 4th axis machining

    Osman Zahid, M. N.; Case, K.; Watts, D. M.

    2016-02-01

    The application of Computer Numerically Controlled (CNC) machining for Rapid Manufacturing processes (CNC-RM) exploits the innate potential of 4th axis machining. The use of an indexer allows the workpiece to be rotated to various orientations which directly increased the region accessible to the cutting tool. However, in order to avoid thin webs and preserve tool life, cutting must be executed with a minimum of three orientations even for geometrically simple parts. Recent findings have suggested the separation of cutting orientations into roughing and finishing operations. Thus, the selection of orientations in finishing processes becomes more flexible and independent. This study was conducted to identify the effects of using a minimum of two cutting orientations in finishing operations for CNC-RM applications. This method is only applicable for non-complex parts where all the features can be machined from two directions. The results of the study illustrate the positive effects of minimizing the number of orientations. Despite improvement in machining operations, the complexity in defining the cutting orientations was also reduced.

    This overview describes the principles of the 4th edition of the European Code against Cancer and provides an introduction to the 12 recommendations to reduce cancer risk. Among the 504.6 million inhabitants of the member states of the European Union (EU28), there are annually 2.64 million new cancer cases and 1.28 million deaths from cancer. It is estimated that this cancer burden could be reduced by up to one half if scientific knowledge on causes of cancer could be translated into successful prevention. The Code is a preventive tool aimed to reduce the cancer burden by informing people how to avoid or reduce carcinogenic exposures, adopt behaviours to reduce the cancer risk, or to participate in organised intervention programmes. The Code should also form a base to guide national health policies in cancer prevention. The 12 recommendations are: not smoking or using other tobacco products; avoiding second-hand smoke; being a healthy body weight; encouraging physical activity; having a healthy diet; limiting alcohol consumption, with not drinking alcohol being better for cancer prevention; avoiding too much exposure to ultraviolet radiation; avoiding cancer-causing agents at the workplace; reducing exposure to high levels of radon; encouraging breastfeeding; limiting the use of hormone replacement therapy; participating in organised vaccination programmes against hepatitis B for newborns and human papillomavirus for girls; and participating in organised screening programmes for bowel cancer, breast cancer, and cervical cancer.

    Ultraviolet radiation (UVR) is part of the electromagnetic spectrum emitted naturally from the sun or from artificial sources such as tanning devices. Acute skin reactions induced by UVR exposure are erythema (skin reddening), or sunburn, and the acquisition of a suntan triggered by UVR-induced DNA damage. UVR exposure is the main cause of skin cancer, including cutaneous malignant melanoma, basal-cell carcinoma, and squamous-cell carcinoma. Skin cancer is the most common cancer in fair-skinned populations, and its incidence has increased steeply over recent decades. According to estimates for 2012, about 100,000 new cases of cutaneous melanoma and about 22,000 deaths from it occurred in Europe. The main mechanisms by which UVR causes cancer are well understood. Exposure during childhood appears to be particularly harmful. Exposure to UVR is a risk factor modifiable by individuals' behaviour. Excessive exposure from natural sources can be avoided by seeking shade when the sun is strongest, by wearing appropriate clothing, and by appropriately applying sunscreens if direct sunlight is unavoidable. Exposure from artificial sources can be completely avoided by not using sunbeds. Beneficial effects of sun or UVR exposure, such as for vitamin D production, can be fully achieved while still avoiding too much sun exposure and the use of sunbeds. Taking all the scientific evidence together, the recommendation of the 4th edition of the European Code Against Cancer for ultraviolet radiation is: "Avoid too much sun, especially for children. Use sun protection. Do not use sunbeds." PMID:26096748

    Full Text Available This study aims to evaluate the effect of phonological awareness training program in preschool performance of 256 children in Funchal, Portugal. This is a longitudinal study from preschool (2005 to 4th grade (2011. It has an experimental design. The sample includes an Experimental Group (132 children and a Control group (124 children. We pretend to answer the following research question: To what degree does training children in phonological awareness as early as preschool have short-term and long-term effects on the evolution of students' competencies and disciplinary knowledge? A first evaluation done in 2006 on the effects of this program at the end of preschool education revealed that the Experimental Group presented significant improvements when compared to the Control Group on the considered dimensions. In 2011, the Experimental Group presented Math National Test higher significant results when compared to the Control Group. The Experimental Group's Portuguese National Test presented better results than the Control Group one, but not significantly. This seems to indicate that Phonological Awareness Program can bring benefits and prevent long-term math school failure.

  18. 4th ATLAS Physics Workshop (Athens) - Report from the Physics Sessions

    Kersevan, B P

    The 4th ATLAS Physics Workshop provided a showcase for studies of some of the most exciting aspects of LHC physics, both within the Standard Model and beyond. It was clear from the wide range of topics covered, from QCD studies to TeV-scale Black Hole production, that preparations are well in hand for understanding whatever Nature, and the LHC, may throw at us. The Standard Model session concentrated on QCD and Electroweak physics, which will form the core of the ATLAS physics program during the first years of LHC operation. Convenor Matt Dobbs began by summarising recent and ongoing studies and pointed out that the first ATLAS papers will aim to prove that we understand LHC physics in the regime where the Standard Model is reliable. Only then will we be able to make convincing claims for the existence of New Physics. Subsequent talks discussed our understanding of this 'bread-and-butter' physics, including minimum bias processes and underlying events (Arthur Moraes), Parton Distribution Functions (Jon Butte...

  2. Technical basis for the internal dosimetry program at the Y-12 Plant

    Since the beginning of plant operations. almost all work with radioactive materials has involved isotopes associated with uranium, enriched or depleted in U235. While limited quantities of isotopes of elements other than uranium are present, workplace monitoring and precess knowledge have established that internal exposure from these other isotopes is insignificant in comparison with uranium. While the changing plant mission may necessitate the consideration of internal exposure from other isotopes at some point in time, only enriched and depleted uranium will be considered in this basis document. The portions of the internal dosimetry technical basis which may be unique to the Y-12 Plant is considered in this manual. This manual presents the technical basis of the routine in vivo and in vitro bioassay programs including choice of frequency, participant selection criteria, and action level guidelines. Protocols for special bioassay will be presented in the chapters which described the basis for intake, uptake, and dam assessment. A discussion of the factors which led to the need to develop a special biokinetic model for uranium at the Y-12 Plant, as well as a description of the model's basic parameters, are included in this document

  3. 2. International Symposium on Nuclear Power Plant Life Management [Opening remarks

    Chairman SUN (or Mr. ZHANG), President KANG and Vice President YU, distinguished guests, and ladies and gentlemen. Good morning. On behalf of the International Atomic Energy Agency, I would like to welcome you to this important international symposium on nuclear power plant life management. In addition, I would like to express our sincere appreciation to the government of China, especially the Chinese Atomic Energy Authority and the China National Nuclear, Corporation in cooperation with the European Commission and the OECD Nuclear Energy Agency for the excellent assistance that they have provided in the preparation and organization of this symposium. Your efforts have been enormous and the hospitality you have demonstrated in the hosting of this symposium has been very generous. It is a great pleasure for me to come to Shanghai and meet with our Chinese colleagues and many other international guests. As you know there are some strong signs of the emergence and rising expectations for the use of nuclear power for generating electricity. This is most obvious here in China and Asia at large. Therefore, it is fitting that we are holding this symposium in this region of the world to enforce the positive and extensive expansion of the peaceful use of nuclear technology for power generation, especially since the focus of the symposium is to encourage the improvement of performance and safety through plant life management programmes in a changing world. The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically for 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate in excess of their design lives. This is not contingent that on the nuclear power plant engineers demonstrating safety and security by analysis, trending, equipment and system upgrades, increased vigilance, testing and ageing management continue operate nuclear power plants beyond

    2012-01-01

    Full Text Available This paper shows the process of inverting the 4th ordered space curve of the first category with a self-intersecting point (with two planes of symmetry and determining its harmonic equivalent. There are harmonic equivalents for five groups of surfaces obtained through the 4th order space curve of the 1st category. Mapping was done through a system of circular cross-sections. Both classical and relativistic geometry interpretations are presented. We also designed spatial models - a spatial model of the pencil of quadrics and a spatial model of the pencil of equivalent quadrics. Besides the boundary surfaces, one surface of the 3rd order, which is an equivalent to a triaxial ellipsoid, passes through this pencil of surface of the 4th order. The center of inversion is located on the contour of the ellipsoid. The parabolic cylinder is mapped into its equivalent, by mapping the contour parabola of the cylinder, in the frontal projection, in relation to the center and the sphere of inversion into a contour curve of the 4th order surface. The generating lines of the parabolic cylinder, which are in a projecting position and pass through the antipode, are mapped into circles (also in a projecting position whose diameters are from the center of inversion to the contour line. The application of the 4th order surfaces in architectural practice is also presented. [Projekat Ministarstva nauke Republike Srbije, br.

  10. Proceedings of the 4th workshop on ion-beam-applied biology

    In order to promote research on biological application using ion beam at TIARA, we have annually hold the Workshop on Ion-beam-applied Biology at JAERI Takasaki since 2002. The 4th workshop entitled 'New Frontiers of Biological Research using microbeam - Application to Radio-microsurgery and Cellular Response to Radiations -' was held on June 22nd, 2005, aimed to overview the recent progress in microbeam-applied researches, and discuss the future direction of application of microbeam not to researches in life science and biotechnology, but also to clinical medicine. This workshop was hosted by JAERI Takasaki, with the cooperation of The Ion Beam Breeding Society, The Japan Radiation Research Society, The Japanese Society for Biological Sciences in Space, The Kanto-Kohetsu Branch of The Atomic Energy Society of Japan, and The Japan Radioisotope Association. There were 104 participants including clinicians attended from universities, public research institutions, and private companies. The papers presented in the workshop were about the ion-beam-applied biological researches at JAERI, the present status of microbeam facilities in Japan and foreign countries, and the microbeam-based analyses of damage repair machinery in insects and radiation-induced bystander effects. It was realized again that microbeam is quite useful for functional analyses by targeted disruption of specific tissues in bio-organisms, and is of critical importance in investigating biological influences of low-dose radiations as well as in its radiological application. These researches using microbeam are expected to further march on. The 13 of the presented papers are indexed individually. (J.P.N.)

  11. European Code against Cancer 4th Edition: Environment, occupation and cancer.

    Espina, Carolina; Straif, Kurt; Friis, Søren; Kogevinas, Manolis; Saracci, Rodolfo; Vainio, Harri; Schüz, Joachim

    2015-12-01

    People are exposed throughout life to a wide range of environmental and occupational pollutants from different sources at home, in the workplace or in the general environment - exposures that normally cannot be directly controlled by the individual. Several chemicals, metals, dusts, fibres, and occupations have been established to be causally associated with an increased risk of specific cancers, such as cancers of the lung, skin and urinary bladder, and mesothelioma. Significant amounts of air pollutants - mainly from road transport and industry - continue to be emitted in the European Union (EU); an increased occurrence of lung cancer has been attributed to air pollution even in areas below the EU limits for daily air pollution. Additionally, a wide range of pesticides as well as industrial and household chemicals may lead to widespread human exposure, mainly through food and water. For most environmental pollutants, the most effective measures are regulations and community actions aimed at reducing and eliminating the exposures. Thus, it is imperative to raise awareness about environmental and occupational carcinogens in order to motivate individuals to be proactive in advocating protection and supporting initiatives aimed at reducing pollution. Regulations are not homogeneous across EU countries, and protective measures in the workplace are not used consistently by all workers all the time; compliance with regulations needs to be continuously monitored and enforced. Therefore, the recommendation on Environment and Occupation of the 4th edition of the European Code against Cancer, focusing on what individuals can do to reduce their cancer risk, reads: "In the workplace, protect yourself against cancer-causing substances by following health and safety instructions."

  12. Learning Natural Selection in 4th Grade with Multi-Agent-Based Computational Models

    Dickes, Amanda Catherine; Sengupta, Pratim

    2013-06-01

    In this paper, we investigate how elementary school students develop multi-level explanations of population dynamics in a simple predator-prey ecosystem, through scaffolded interactions with a multi-agent-based computational model (MABM). The term "agent" in an MABM indicates individual computational objects or actors (e.g., cars), and these agents obey simple rules assigned or manipulated by the user (e.g., speeding up, slowing down, etc.). It is the interactions between these agents, based on the rules assigned by the user, that give rise to emergent, aggregate-level behavior (e.g., formation and movement of the traffic jam). Natural selection is such an emergent phenomenon, which has been shown to be challenging for novices (K16 students) to understand. Whereas prior research on learning evolutionary phenomena with MABMs has typically focused on high school students and beyond, we investigate how elementary students (4th graders) develop multi-level explanations of some introductory aspects of natural selection—species differentiation and population change—through scaffolded interactions with an MABM that simulates predator-prey dynamics in a simple birds-butterflies ecosystem. We conducted a semi-clinical interview based study with ten participants, in which we focused on the following: a) identifying the nature of learners' initial interpretations of salient events or elements of the represented phenomena, b) identifying the roles these interpretations play in the development of their multi-level explanations, and c) how attending to different levels of the relevant phenomena can make explicit different mechanisms to the learners. In addition, our analysis also shows that although there were differences between high- and low-performing students (in terms of being able to explain population-level behaviors) in the pre-test, these differences disappeared in the post-test.

  13. Summary of the 4th workshop on the reduced-moderation water reactor

    The research on Reduced-Moderation Water Reactors (RMWRs) has been performed in JAERI for the development of future innovative reactors. The workshop on the RMWRs has been held every year since fiscal 1997 aimed at information exchange between JAERI and other organizations such as universities, laboratories, utilities and vendors. The 4th workshop was held on March 2, 2001 under the joint auspices of JAERI and North Kanto branch of Atomic Energy Society of Japan. The workshop began with three lectures on recent research activities in JAERI entitled 'Recent Situation of Research on Reduced-Moderation Water Reactor', 'Analysis on Electricity Generation Costs of Reduced Moderation Water Reactors' and 'Reprocessing Technology for Spent Mixed-Oxides Fuel from LWR'. Then five lectures followed: 'Micro Reactor Physics of MOX Fueled LWR' which shows the recent results of reactor physics, Fast Reactor Cooled by Supercritical Light Water' which is another type of reduced-moderation reactor, 'Phase 1 of Feasibility Studies on Commercialized Fast Breeder Reactor Cycle System' mainly conducted by Japan Nuclear Cycle Development Institute (JNC), 'Integral Type Small PWR with Stand-alone Safety' which is intended to suit for the future consumers' needs, and Utilization of Plutonium in Reduced-Moderation Water Reactors' which dictates benefits of plutonium utilization with RMWRs. This report includes the original papers presented at the workshop and summaries of the questions and answers for each lecture, as well as presentation handouts, program and participant list as appendixes. The 8 of the presented papers are indexed individually. (J.P.N.)

    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. Internal dose assessment for environmental monitoring in nuclear power plant accidents

    Mianji Fereidoun A.

    2013-01-01

    Full Text Available A method for exploiting human's internal contamination data for radioactive release estimation in nuclear power plant accidents is proposed. Nevertheless, such data is often very rough and uncertain; it is accessible even in toughest situations when most of the active and passive monitors are damaged by the accident. These data can be used in combination with other collectable data for estimating the event scale in severe nuclear power plan accidents. The rationale behind the method is that nuclear power plant accidents are often associated with internal contamination of radiation workers involved in the early stages of emergency response activities mainly due to the release of 131I in atmosphere. The proposed inverse analytical approach uses the 131I intake of contaminated workers, their working conditions, chronology of events, and applied personal safety measures during the first hours or days of the emergency response activities to estimate the magnitude of 131I concentration in the air.

  20. The nature of the 4th track in GX 5-1: discovery of Fe XXVI RRC in massive flares

    Church, M J; Peach, C; Balucinska-Church, M

    2009-01-01

    We present an explanation of the 4th branch of the Z-track based on analysis of high-quality RXTE data on the source GX 5-1. Spectral analysis shows that the physical evolution on the 4th track is a continuation of the flaring branch which we previously proposed consists of unstable nuclear burning of the accretion flow on the neutron star. In flaring there is a huge increase of the neutron star emission from a volume that increases to a radius of 21 km. The 4th branch is shown to consist of flaring under conditions that the mass accretion rate and thus the total source luminosity is falling. We detect strong emission on the flaring and 4th branches at energies between 7.8 - 9.4 keV inconsistent with origin as Fe K emission, which we suggest is the radiative recombination continua (RRC) of iron Fe XXVI at 9.28 keV and of lower states. Evolution of the emission takes place, the energy falling but the flux increasing strongly, consistent with production in the large volume of unstable nuclear burning around the...

  12. The Place and Importance of Values Education in 4.th and 5th. Grade Primary School Social Studies Textbooks

    Mehmet Fatih Yiğit

    2013-11-01

    Full Text Available The term ‘value’ has been used in many different meanings until today in different areas and it has been the reason for confusion in values education. In this sense, Weber (1990 has stated that different approaches to the term ‘value’ have played a negative role for the production of values. Kohlberg (1981 has defined ‘value’ as giving moral decisions and acting accordingly while Hill (1991 interpreted values as the beliefs that people care and direct the life of individuals. On the other hand, Veugelers (2000 defined values as the beliefs that help individuals to decide what is good or evil. International organizations also saw the need to define values in accordance with their missions. In the Declaration of Human Rights by the United Nations, it is indicated that education should strengthen human rights and freedom while supporting tolerance among different religious groups, ethnicities and nations (Universal Declaration of Human Rights, 1948. UNESCO is another organization that defined the role of values in education. According to the report by UNESCO, education becomes valuable if one learns (a how to know (b how to do, (c how to live together and (d how to be. In this sense, UNESCO has also claimed that in order to develop intercultural and interfaith dialogue, common values accepted by everyone should be given in schools. It has been observed that critical thinking and problem solving skills were given in values education programs in western societies while those skills have started to be taught in Turkey recently. In this study, the main values education movements and the processes and principles of teaching values education in real life are analyzed. We looked at the place of values education in 4th and 5th grade Social Studies textbooks in Turkey. After analyzing the basic processes and principles of values education, we looked at the values to be given to the students in the textbooks. Values education approaches have

  14. Reviewing the safety of existing nuclear power plants. Proceedings of an international symposium

    The Symposium on Reviewing the Safety of Existing Nuclear Power Plants was held from 8 to 11 October 1996 at the Austria Center in Vienna. It was organized by the IAEA in co-operation with the Nuclear Energy Agency of the OECD (OECD/NEA). About 160 experts from 37 countries and three international organizations took part. The participants represented nuclear power plant owners, operators, regulators, technical support organizations, designers and manufacturers. The Symposium was a follow-up to the 1991 International Conference on The Safety of Nuclear Power: Strategy for the Future. This Conference will be remembered as the initiating force behind the Convention on Nuclear Safety, which entered into force on 24 October 1996. The Conference also formulated recommendations for future actions by both national and international organizations aimed at ensuring the safety of nuclear power. The goal of the present Symposium was to review the progress made in implementing the recommendations of the 1991 Conference relating to the safety of existing nuclear power plants, and to make available to all those involved in maintaining the safety of nuclear power plants information on effective methods, practices and criteria for safety review and operating experience feedback systems. The main Symposium sessions addressed the following topics: elements of the nuclear power safety strategy; ongoing safety reviews; periodic safety reviews; safety reviews of special issues and feedback of operating experience. In addition to the main sessions, two poster sessions illustrated safety assessment methods and experience; and information databases and operating experience feedback. In the closing Panel, the basis for continued safe operation of nuclear power plants was discussed

  15. Balance between automation and human actions in nuclear power plant operation. Results of international cooperation

    Automation has long been an established feature of power plants. In some applications, the use of automation has been the significant factor which has enabled plant technology to progress to its current state. Societal demands for increased levels of safety have led to greater use of redundancy and diversity and this, in turn, has increased levels of automation. However, possibly the greatest contributory factor in increased automation has resulted from improvements in information technology. Much recent attention has been focused on the concept of inherently safe reactors, which may simplify safety system requirements and information and control system complexity. The allocation of tasks between man and machine may be one of the most critical activity in the design of new nuclear plants and major retro-fits and it therefore warrants a design approach which is commensurate in quality with the high levels of safety and production performance sought from nuclear plants. Facing this climate, in 1989 the International Atomic Energy Agency (IAEA) formed an advisory group from member countries with extensive experience in nuclear power plant automation. The task of this group was to advise on the appropriate balance between manual and automatic actions in plant operation. (author)

  17. Lessons Learned in International Safeguards - Implementation of Safeguards at the Rokkasho Reprocessing Plant

    Ehinger, Michael H [ORNL; Johnson, Shirley [Tucker Creek Consulting

    2010-02-01

    The focus of this report is lessons learned at the Rokkasho Reprocessing Plant (RRP). However, the subject of lessons learned for application of international safeguards at reprocessing plants includes a cumulative history of inspections starting at the West Valley (New York, U.S.A.) reprocessing plant in 1969 and proceeding through all of the efforts over the years. The RRP is the latest and most challenging application the International Atomic Energy Agency has faced. In many ways the challenges have remained the same, timely inspection and evaluation with limited inspector resources, with the continuing realization that planning and preparations can never start early enough in the life cycle of a facility. Lessons learned over the years have involved the challenges of using ongoing advances in technology and dealing with facilities with increased throughput and continuous operation. This report will begin with a review of historical developments and lessons learned. This will provide a basis for a discussion of the experiences and lessons learned from the implementation of international safeguards at RRP.

  18. The nuclear materials control and accountability internal audit program at the Oak Ridge Y-12 plant

    The internal audit program of the Nuclear Material Control and Accountability (NMCandA) Department at the Oak Ridge Y-12 Plant, through inventory-verification audits, inventory-observation audits, procedures audits, and records audits, evaluates the adequacy of material accounting and control systems and procedures throughout the Plant; appraises and verifies the accuracy and reliability of accountability records and reports; assures the consistent application of generally accepted accounting principles in accounting for nuclear materials; and assures compliance with the Department of Energy (DOE) and NMCandA procedures and requirements. The internal audit program has significantly strengthened the control and accountability of nuclear materials through improving the system of internal control over nuclear materials, increasing the awareness of materials control and accountability concerns within the Plant's material balance areas (MBAs), strengthening the existence of audit trails within the overall accounting system for nuclear materials, improving the accuracy and timeliness of data submitted to the nuclear materials accountability system, auditing the NMCandA accounting system to ensure its accuracy and reliability, and ensuring that all components of that system (general ledgers, subsidiary ledgers, inventory listings, etc.) are in agreement among themselves

  19. Increase of Internal CO2 of Cotton Plants by Methanol Application to Increase Yield

    A field experiment has been conducted to increase internal CO2 and Rubisco activity detected by 14C and to determinate which factors influence this activities. Plant material used was cotton plants which internal CO2 concentrations and Rubisco activity was observed at 35, 50, 65, 80 days after planting (DAP). Treatments applied were methanol with concentrations of 0%, 10%,20% and 30% at available water (AW) at 25-50% AW, 50-75% AW, 75-100% AW. Results obtained showed that application of methanol at concentration of 20% at 75-100% AW, increase internal CO2 from 266.60 ppm to 295.10 ppm (11 % increase) and this will also increase Rubisco activity from 3.81 to 14.28 (μmol. CO2 menit-1 (μmol. Rubisco-1). This increase is expected to push photosynthesis rate and result in increase cotton yield. The use of 14C was satisfactorily detected the amount of carbon. (author)

  2. Book of Abstracts of 4th International Conference: Nuclear Option in Countries with Small and Medium Electricity Grids

    In order to achieve best safety and operational standards these countries with limited human and material resources must put added emphasis on their rational and efficient use. Consequently, the worldwide developments on innovative reactors' systems and improved concepts for fuel utilisation and waste disposal are of substantial interest. Appropriate selections of reactor technology, fuel cycle and decommission strategies are of paramount importance. There are very successful examples of achieving safety and good operational records, so the exchange of experience and co-operation amongst that group of countries is of great interest. Exchanging specific experience and co-operation between the like countries will be additional value relative to the still prevailing equipment supplier-national utility relationships

  6. An international comparison of commercial nuclear power plant staffing regulations and practice, 1980--1990

    In this report an international review of regulatory and industry practices is provided in the area of nuclear power plant staffing during the 1980s in Canada, France, Germany, Japan, Sweden, and the United Kingdom. The objective of this review is to highlight trends in staffing regulatory approaches, industry practices, and issues of concern in other countries that have potential relevance to nuclear power plant staffing issues in the United States. The decade of the 1980s was marked by a great deal of growth in nuclear power operations internationally; however, growth of nuclear power is not expected to continue in the 1990s except in France and Japan. A continuum of regulatory approaches to staffing was identified, ranging from prescribed regulations that are applied to all licensees (Germany is most similar to the United States in this regard), to indirect staffing regulations where the regulatory authority oversees plant operating practices that are agreed to in the plant operating license (most notably, France and the United Kingdom). Most of the changes observed in staffing regulations and practices in the early 1980s were made in response to the accident at the Three Mile Island Unit 2 nuclear power plant (TMI) in 1979. These changes included the widespread issuance of new operator and licensing requirements and the establishment of national training centers. After the post-TMI changes were implemented, a period of relative stability followed. Changes in the latter half of the 1980s have focused on continuing improvements and additions to training curricula and methods, most notably increased reliance on simulator training

The reports are organized as follows: CNSNS-TR-004 Volume 1: Introduction and Methodology. CNSNS-TR-004 Volume 2: Initiating Event and Accident Sequences. CNSNS-TR-004 Volume 3: System Analysis. CNSNS-TR-004 Volume 4: Accident Sequence Quantification and Results. CNSNS-TR-004 Volume 5: Appendices A, B and C. This volume presents the results of the system analysis for the Laguna Verde Unit 1 Nuclear Power Plant. The system analysis involved the development of logical models for all the systems included in the accident sequence event tree headings, and for all the support systems required to operate the front line systems. For the Internal Event analysis for Laguna Verde, 16 front line systems and 5 support systems were included. Detailed fault trees were developed for most of the important systems. Simplified fault trees focusing on major faults were constructed for those systems that can be adequately represent,ed using this kind of modeling. For those systems where fault tree models were not constructed, actual data were used to represent the dominant failures of the systems. The main failures included in the fault trees are hardware failures, test and maintenance unavailabilities, common cause failures, and human errors. The SETS and TEMAC codes were used to perform the qualitative and quantitative fault tree analyses. (Author)

  8. PREFACE: The 4th Symposium on the Mechanics of Slender Structures (MoSS2013)

    Cao, Dengqing; Kaczmarczyk, Stefan

    2013-07-01

    This volume of Journal of Physics: Conference Series contains papers presented at the 4th Symposium on the Mechanics of Slender Structures (MoSS2013) run under the auspices of the Institute of Physics Applied Mechanics Group and hosted by Harbin Institute of Technology (China) from 7-9 January 2013. The conference has been organized in collaboration with the Technical Committee on Vibration and Sound of the American Society of Mechanical Engineers and follows a one day seminar on Ropes, Cables, Belts and Chains: Theory and Applications and the MoSS2006 symposium held at the University of Northampton (UK) in 2004 and 2006, respectively, the MoSS2008 symposium held at the University of Maryland Baltimore County (USA) in 2008 and the MoSS2010 symposium hosted by Mondragon University and held in San Sebastian (Spain) in 2010. The remit of the Symposium on the Mechanics of Slender Structures series involves a broad range of scientific areas. Applications of slender structures include terrestrial, marine and space systems. Moving elastic elements such as ropes, cables, belts and tethers are pivotal components of many engineering systems. Their lengths often vary when the system is in operation. The applications include vertical transportation installations and, more recently, space tether propulsion systems. Traction drive elevator installations employ ropes and belts of variable length as a means of suspension, and also for the compensation of tensile forces over the traction sheave. In cranes and mine hoists, cables and ropes are subject to length variation in order to carry payloads. Tethers experiencing extension and retraction are important components of offshore and marine installations, as well as being proposed for a variety of different space vehicle propulsion systems based on different applications of momentum exchange and electrodynamic interactions with planetary magnetic fields. Furthermore, cables and slender rods are used extensively in civil engineering

  9. Coronal MR imaging of the normal 3rd, 4th, and 5th lumbar and 1st sacral nerve roots

    Seven healthy volunteers underwent coronal MR imaging at 1.5 tesla of the normal 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots. Coronal slices, 3-mm-thick with a 0.3-mm gap between the slices were obtained (TR/TE 600/22) through the lumbar spinal canal. All the nerve roots were visible on at least one image. One can routinely expect to demonstrate the 3rd, 4th, and 5th lumbar, and 1st sacral nerve roots on T1-weighted, 3-mm-thick coronal MR scans. We found no correlation between the degree of lumbar lordosis and the lengths of the visible nerve roots. Five patients with one of the following spinal problems: anomaly, tumor, disk herniation, and failed back surgery syndrome were examined according to our protocol. In all these cases coronal MR imaging gave the correct diagnosis. (orig.)

  19. Recalibrating the Sunspot Number (SN): The 3rd and 4th SN Workshops

    Cliver, E. W.; Clette, F.; Svalgaard, L.; Vaquero, J. M.

    At the XIIth Hvar Astrophysical Colloquium in 2012, we reviewed the progress of an effort begun in 2011 to recalibrate the sunspot number (SN). That work is now nearing completion and we review the motivation, approach, and results of this process which was conducted via a series of four international workshops. Previously we discussed the principal results of workshops at Sunspot in 2011 and Brussels in 2012. These involved the identification of discontinuities circa 1885 in the Hoyt and Schatten Group SN and 1945 in the International SN. Subsequently, workshops were held in Tucson (2013) and Locarno (2014). Key results during the time of these two workshops included: (1) development of an independent ''backbone'' method for determining the Group sunspot number; (2) identification of post-1970 inhomogeneities in the Group SN and the International SN; (3) construction of preliminary revisions of the Group SN from 1610-present and the International SN from 1700--present; (4) reassessment (ongoing) of the Hoyt and Schatten Group SN data base from 1610-present; and (5) establishment of a SN archive at the University of Extremadura. The release of the new International and Group SN series is anticipated during the second half of 2015 and procedures are being put in place both to maintain the calibration of these two series and to produce subsequent revisions should more historical data be unearthed or new inhomogeneities in the series be uncovered or arise.

  1. International safeguards at the feed and withdrawal area of a gas centrifuge uranium enrichment plant

    This paper discusses the application of International Atomic Energy Agency (IAEA) safeguards at a model gas centrifuge uranium enrichment plant designed for the production of low-enriched uranium; particular emphasis is placed upon the verification by the IAEA of the facility material balance accounting. After reviewing the IAEA safeguards objectives and concerns at such a plant, the paper describes the material accountancy performed by the facility operator, and discusses strategies by which the operator might attempt to divert a portion of the declared nuclear materials. Finally, the paper discusses the verification of the declared material balance, including sampling strategies, attributes and variables measurements, and nondestructive measurements to improve the efficiency of the inspection measures

  2. Internal fluid flow management analysis for Clinch River Breeder Reactor Plant sodium pumps

    The Clinch River Breeder Reactor Plant (CRBRP) sodium pumps are currently being designed and the prototype unit is being fabricated. In the design of these large-scale pumps for elevated temperature Liquid Metal Fast Breeder Reactor (LMFBR) service, one major design consideration is the response of the critical parts to severe thermal transients. A detailed internal fluid flow distribution analysis has been performed using a computer code HAFMAT, which solves a network of fluid flow paths. The results of the analytical approach are then compared to the test data obtained on a half-scale pump model which was tested in water. The details are presented of pump internal hydraulic analysis, and test and evaluation of the half-scale model test results

  6. An international comparison of regulatory organizations and licensing procedures for new nuclear power plants

    This paper considers measures needed to license new nuclear power plants efficiently. We base our analysis on international standards and a comparison of the national regulatory and licensing framework in seven countries (Canada, France, Germany, Japan, Switzerland, the UK and the USA). We split the review into the organization of regulatory responsibilities and the licensing process. We propose a set of considerations that should be incorporated into national solutions. While conscious of the different cultural fundamentals of each region, we hope this paper will help fuel an emerging debate on this highly topical issue

  8. International feedback and safety reassessment - The French FBFC nuclear fuel fabrication plant case

    With a ten year periodicity the French nuclear safety authority (DGSNR) and its technical support (IRSN) reassess the safety of the plants under survey. A special part is devoted to internal experience feedback and the events that occurred during the past working period are carefully analysed. In the case of the French FBFC uranium fuel fabrication plant, it was decided to make a more systematic use of international feedback in the usual reassessment work for non-reactor facilities. A program has been set up on the basis of peer-to-peer level bi-lateral meetings organized with the European safety authorities having similar plant under their responsibility. A special safety oriented standard questionnaire was previously sent to each and returned. Each bilateral contact consists of a two-day visit, which began with discussions about particular topics in the regulation area and methods for an efficient survey. In order to illustrate this, the two authorities visited the nuclear site the second day. In this way, European safety authorities of five countries (Belgium, Germany, United-Kingdom, Spain and Sweden) have met and plants belonging to FRAMATOME-ANP, WESTINGHOUSE and ENUSA groups visited. All the contacted authorities participated and when, this program was completed, it was possible for DGSNR and IRSN to get a more accurate measure of particular reassessment work. The main results of these actions were to 'standardize' the consultancy's judgement, and taking advantage of encountered good safety practices and good safety designs it was possible to reinforce specific requests during the reassessment work. Moreover, it was an opportunity for the operators to participate in deepening information exchanges about safety topics. (author)

  9. Safeguards Guidance for Designers of Commercial Nuclear Facilities - International Safeguards Requirements for Uranium Enrichment Plants

    For the past two years, the United States National Nuclear Security Administration, Office of International Regimes and Agreements (NA-243), has sponsored the Safeguards-by-Design Project, through which it is hoped new nuclear facilities will be designed and constructed worldwide more amenable to nuclear safeguards. In the course of this project it was recognized that commercial designer/builders of nuclear facilities are not always aware of, or understand, the relevant domestic and international safeguards requirements, especially the latter as implemented by the International Atomic Energy Agency (IAEA). To help commercial designer/builders better understand these requirements, a report was prepared by the Safeguards-by-Design Project Team that articulated and interpreted the international nuclear safeguards requirements for the initial case of uranium enrichment plants. The following paper summarizes the subject report, the specific requirements, where they originate, and the implications for design and construction. It also briefly summarizes the established best design and operating practices that designer/builder/operators have implemented for currently meeting these requirements. In preparing the subject report, it is recognized that the best practices are continually evolving as the designer/builder/operators and IAEA consider even more effective and efficient means for meeting the safeguards requirements and objectives.

    The internal dosimetry program at the Instituto de Pesquisas Energeticas e Nucleares, IPEN, is accomplished in two steps: the activity measurements are performed at the In Vivo Monitoring Laboratory and subsequently the data analysis and the dose evaluation are carried out by the Dose Calculation Group according to the ICRP models. The objective of this study is to take the whole body and thyroid monitoring results recorded from 2005 to 2015 to see whether the internal contamination control procedure for workers were suitable even with the increase in the radiopharmaceutical production. The study were based in a research called “Search of Variables” for the operations carried out in the restricted areas of radiopharmaceutical production plant, taking into account the dose distribution data for all the tasks recorded by the radioprotection service. This methodology aims to identify and determine the principal variables that impact on the worker's dose. The results were presented for the following variables: individual occupationally exposed, operation variable, area/cell, type of task of operation, which depend on the variable dose. In spite of growth rate in the production of radiopharmaceutical, this study has shown that the improvements in the plant have contributed to the dose reduction of the workers. (author)

  15. Model of a Generic Natural Uranium Conversion Plant ? Suggested Measures to Strengthen International Safeguards

    Raffo-Caiado, Ana Claudia [ORNL; Begovich, John M [ORNL; Ferrada, Juan J [ORNL

    2009-11-01

    This is the final report that closed a joint collaboration effort between DOE and the National Nuclear Energy Commission of Brazil (CNEN). In 2005, DOE and CNEN started a collaborative effort to evaluate measures that can strengthen the effectiveness of international safeguards at a natural uranium conversion plant (NUCP). The work was performed by DOE s Oak Ridge National Laboratory and CNEN. A generic model of a NUCP was developed and typical processing steps were defined. Advanced instrumentation and techniques for verification purposes were identified and investigated. The scope of the work was triggered by the International Atomic Energy Agency s 2003 revised policy concerning the starting point of safeguards at uranium conversion facilities. Prior to this policy only the final products of the uranium conversion plant were considered to be of composition and purity suitable for use in the nuclear fuel cycle and therefore, subject to the IAEA safeguards control. DOE and CNEN have explored options for implementing the IAEA policy, although Brazil understands that the new policy established by the IAEA is beyond the framework of the Quadripartite Agreement of which it is one of the parties, together with Argentina, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) and the IAEA. Two technical papers on this subject were published at the 2005 and 2008 INMM Annual Meetings.

    Current industry and NRC guidance documents such as IEEE 7-4.3.2, Reg. Guide 1.152, and IEEE 603 do not sufficiently define a level of detail for evaluating interdivisional communications independence. The NRC seeks to establish criteria for safety systems communications that can be uniformly applied in evaluation of a variety of safety system designs. This report focuses strictly on communication issues related to data sent between safety systems and between safety and nonsafety systems. Further, the report does not provide design guidance for communication systems nor present detailed failure modes and effects analysis (FMEA) results for existing designs. This letter report describes communications between safety and nonsafety systems in nuclear power plants outside the United States. A limited study of international nuclear power plants was conducted to ascertain important communication implementations that might have bearing on systems proposed for licensing in the United States. This report provides that following information: 1.communications types and structures used in a representative set of international nuclear power reactors, and 2.communications issues derived from standards and other source documents relevant to safety and nonsafety communications. Topics that are discussed include the following: communication among redundant safety divisions, communications between safety divisions and nonsafety systems, control of safety equipment from a nonsafety workstation, and connection of nonsafety programming, maintenance, and test equipment to redundant safety divisions during operation. Information for this report was obtained through publicly available sources such as published papers and presentations. No proprietary information is represented.

  17. The Waste Isolation Pilot Plant: A Success Story with International Cooperation

    Matthews, M.

    2002-02-26

    The U.S. Department of Energy (DOE) Carlsbad Field Office (CBFO) administers and operates the Waste Isolation Pilot Plant (WIPP) site, which hosts a deep geologic repository for safe disposal of U.S. defense-related TRU waste and is located 42 kilometers (km) east of Carlsbad, New Mexico. CBFO also manages the National Transuranic Waste Program (NTP), which oversees TRU waste management from generation to disposal. The WIPP began receiving waste in March 1999. In some areas of broad international interest, the CBFO has developed a leading expertise through its 25-year WIPP repository and TRU waste characterization activities. In addition to participating in relevant and beneficial experiments, the CBFO will provide the international community convenient access to this information by sponsoring and hosting symposia and workshops on relevant topics and by participation in international waste management organizations and topical meetings. In recognition of the successes at WIPP, the Inter national Atomic Energy Agency (IAEA) has designated WIPP as an International Center of Excellence and part of IAEA's Network of Centers of Excellence. The IAEA will foster cooperative training in and demonstration of waste disposal technologies in underground research facilities (URFs).such as WIPP. The CBFO, supported by its Science Advisor, has agreed to exchange scientific information with eight foreign radioactive waste management organizations, and three more national radioactive waste management and disposal organizations have expressed interest in similar agreements. These activities result in the cost-effective acquisition of scientific information in support of increased WIPP facility operational and post-closure assurance and reliability. It also demonstrates the CBFO's intent and resolve to honor international commitments and obligations.

  19. Application of the international guidelines for machinery breakdown prevention at nuclear power plants

    For more than forty years as a specialized branch of the worldwide insurance industry, the nuclear insurance pools have underwritten property damage protection for nuclear facilities throughout the world. At power plants insured by the pools, an enviable record of operational safety has been attained. Nevertheless, electrical and mechanical equipment does break down occasionally. Although these failures do not necessarily compromise nuclear safety, they can cause significant damage to equipment, leading to a considerable loss of generating revenue and causing sizeable insurance losses. Since insurance companies have a large financial stake in nuclear power plants, their goal is to minimize insurance losses, including the failure of systems and equipment and ensuing consequential damages. To ensure that the insurance risk is properly underwritten, insurance companies analyze loss information, develop loss prevention guidelines and focus loss control activities on those areas where insurance risk is most significant. This paper provides a chronology of the development of the ''International Guidelines for Machinery Breakdown Prevention at Nuclear Power Plants'' and describes the results of insurance inspections conducted using these guidelines. Included is a summary of guideline content and of insurance loss experience between 1962 and 1999. (author)

  20. Application of the international union of radioecologists soil-to-plant database to Canadian settings

    Over ten years the International Union of Radioecologists (IUR) has amassed a large database on the soil-to-plant transfer of elements. Many of the studies were established using standardized experimental protocols, so that the opportunity for intercomparison is unparalleled among environmental transfer parameter databases. Although most contributors are from Europe, the database includes contributions from Canada and other non-European nations. For Cs, Sr, Co, Pu and Np there are 2035, 920, 782, 679 and 465 records, and there are also some records for Ag, Am, Ce, Cm, 1, La, Mn, Ni, Pb, Po, Ra, Ru, Sb, Tc, Th, U and Zn. An earlier analysis of the database was used to support the statistical distributions of the soil-to-plant transfer parameters applied for the assessment of Canada's nuclear fuel waste concept. The present project re-examines the full database and broadens the application. In many cases, the crops, soils and environmental conditions investigated by the IUR are very applicable to Canadian settings. For several elements, there are sufficient data to develop useful relationships between soil-to-plant transfer and the properties of the soil, although the variation of the transfer values remains large. The resulting estimated parameter values will be useful in many nuclear environmental safety assessments. (author)

  1. Caldecott 4th bore tunnel project: influence of ground water flows and inflows triggered by tectonic fault zones?

    The 4th Bore is a highway tunnel on California State Route 24 currently under construction. The 4th Bore is undertaken by the California State Department of Transportation (CALTRANS) and the Contra Costa County Transportation Commission (CCTC) to alleviate traffic congestion on SR24 connecting the cities of Oakland and Orinda in the San Francisco East Bay Area. The cost for the 4th Bore is estimated at $ 390.8 Mill. The 3,249 ft long 4th Bore tunnel will have excavated dimensions of approximately 40 ft height and 49 ft width. A total of 7 cross passages will run between the 3rd and the new 4th bore. Geology and Hydrogeology: The project is located in the Oakland Berkeley Hills of the SF Bay Area. The Caldecott Tunnels lie within the easterly assemblage of the Hayward fault zone province which consists of a sequence of sedimentary and volcanic rocks that accumulated in the interval between about 16 and 8.4 Ma (Miocene). The basal rocks of these Tertiary deposits consist of deep marine basin sediments of the Monterey Group. These rocks are overlain uncomfortably by an interbedded sequence of terrestrial sediments (Orinda Formation) and volcanic rocks (Moraga Formation). The Tertiary rocks have been folded into large amplitude, NW trending folds that are cut by N trending strike and slip faults. The SF Bay Region, which is crossed by 4 major faults (San Gregorio, San Andreas, Hayward, and Calaveras), is considered one of the more seismically active regions of the world. The active Hayward fault lies 0.9mi to the west of the Caldecott Tunnels and is the closest major fault to the project area. The tunnel is at the moment under top heading construction: West Portal (360ft) and East Portal (1,968.5ft). While major faults typically influence groundwater flow, characterization of such influences is extremely difficult because of the heterogeneity of the hydraulic systems and the different lithological parameters and influences. Four major inactive fault zones striking

    2012-02-01

    Full Text Available In 2005, 62% of pupils who sat the 4th grade literacy and numeracy examination attained mastery, which increased to 67% in 2009 from 50% in 2001. No study has examined the role of self-esteem on the academic performance of Jamaican 4th graders. The main objectives were, 1 evaluate the influence of selfesteem on academic performance, 2 determine factors that account for changes in self-esteem, and 3 examine factors of academic performance. The sample for this research was one hundred and twenty (120 respondents. Multiple repression techniques were conducted to identify variables explaining performance, with self-esteem being among the variables. A p-value ≤0.10 was used to indicate statistical significance. There is a positive correlation between self-esteem and academic performance (rs = 0.611, p<0.0001. Four variables emerged as statistical significant factors of self-esteem-academic performance, age of respondents, gender and parental behaviour, which explain 64.4% of the variability in self-esteem. Boys had a lower self-esteem (b = -3.911 than their female counterparts. Self-esteem is the most influential factor that account for academic performance. Of the nine variables used, four emerged as explaining academic performance, which explained 73.6% of the variability in academic performance. The emerging findings and knowledge gleaned from this work present a critical guide and a framework for policy practitioners to implement measure that can effectively address low performance among 4th graders.

  10. Technical Program of The 4th World Congress on Chemical, Biological and Radiological Terrorism

    Many countries worldwide were interested in the part that CBMTS industry played in the overall protection schemes required of all nations. It was idea to develop a baseline of information on antidotes and planned medical treatment for military and civilian medical casualties, in both peace and war. Based on actual incidents that affected their chemical, petrochemical and pharmaceutical industries during their recent war, countries highlighted a danger that every country could face in the event of military actions, sabotage and especially terrorist actions, as well as major incidents or accidents involving these industries. It is great importance of CBMTS approach at bringing together the world's very best professionals in science and medicine to explore at the outer edges of science and technology, the most important issue facing the international community. Participants put big efforts towards defining the issues, surfacing the problems across the NBC science and medical spectrum and applying the best efforts at developing solutions that would most benefit our world community

  11. International symposium on induced mutations in plants (ISIM). Book of abstracts

    The year 2008 will mark the 80th anniversary of mutation induction in crop plants. The application of mutation techniques, i.e. gamma rays and other physical and chemical mutagens, has generated a vast amount of genetic variability and has played a significant role in plant breeding and genetic studies. The widespread use of induced mutants in plant breeding programmes throughout the world has led to the official release of more than 2600 mutant crop varieties. A large number of these varieties (including cereals, pulses, oil, root and tuber crops, and ornamentals) have been released in developing countries, resulting in enormous positive economic impacts. The International Symposium on Induced Mutations in Plants (ISIM) will be the eighth in the Joint FAO/IAEA Programme's Symposium series dedicated exclusively to harnessing and disseminating information on current trends in induced mutagenesis in plants, the first of which was held in 1969 and the last in 1995. These previous symposia dealt with themes relating to the development of efficient protocols for induced mutagenesis and their role in the enhancement of quality traits, as well as resistance to biotic and abiotic stresses in crops and the integration of in vitro and molecular genetic techniques in mutation induction. Since 1995, there has been an increased interest within the scientific community, not only in the use of induced mutations for developing improved crop varieties and for the discovery of genes controlling important traits and in the understanding the functions and mechanisms of actions of these genes, but also in deciphering the biological nature of DNA damage, repair and mutagenesis. A symposium that brings together the key players in basic research, as well as in the development and application of technologies relating to the efficient use of induced mutations for crop improvement and empirical genetic studies, is therefore justified and necessary. Topics addressed at the symposium

  12. Collaborative interactions between type 2 innate lymphoid cells and antigen-specific CD4+ Th2 cells exacerbate murine allergic airway diseases with prominent eosinophilia.

    Liu, Bo; Lee, Jee-Boong; Chen, Chun-Yu; Hershey, Gurjit K Khurana; Wang, Yui-Hsi

    2015-04-15

    Type-2 innate lymphoid cells (ILC2s) and the acquired CD4(+) Th2 and Th17 cells contribute to the pathogenesis of experimental asthma; however, their roles in Ag-driven exacerbation of chronic murine allergic airway diseases remain elusive. In this study, we report that repeated intranasal rechallenges with only OVA Ag were sufficient to trigger airway hyperresponsiveness, prominent eosinophilic inflammation, and significantly increased serum OVA-specific IgG1 and IgE in rested mice that previously developed murine allergic airway diseases. The recall response to repeated OVA inoculation preferentially triggered a further increase of lung OVA-specific CD4(+) Th2 cells, whereas CD4(+) Th17 and ILC2 cell numbers remained constant. Furthermore, the acquired CD4(+) Th17 cells in Stat6(-/-)/IL-17-GFP mice, or innate ILC2s in CD4(+) T cell-ablated mice, failed to mount an allergic recall response to OVA Ag. After repeated OVA rechallenge or CD4(+) T cell ablation, the increase or loss of CD4(+) Th2 cells resulted in an enhanced or reduced IL-13 production by lung ILC2s in response to IL-25 and IL-33 stimulation, respectively. In return, ILC2s enhanced Ag-mediated proliferation of cocultured CD4(+) Th2 cells and their cytokine production, and promoted eosinophilic airway inflammation and goblet cell hyperplasia driven by adoptively transferred Ag-specific CD4(+) Th2 cells. Thus, these results suggest that an allergic recall response to recurring Ag exposures preferentially triggers an increase of Ag-specific CD4(+) Th2 cells, which facilitates the collaborative interactions between acquired CD4(+) Th2 cells and innate ILC2s to drive the exacerbation of a murine allergic airway diseases with an eosinophilic phenotype.

  13. International comparison of construction economics of nuclear power plants using the referred investment cost method

    The described method of referred capital investment costs helps to increase the reliability of international comparison of the economics of constructing large capital investment plants with particular orientation to nuclear power stations. The method is based on utility functions which assess the level of material consumption and labor necessary for constructing nuclear power stations, expressed in indicators for the power stations compared and referenced. The resulting technical level of the design project and its components form the basis for referencing the expended investment costs (or prices) and for computing the comparison coefficient. The coefficient is a synthetic expression of the ratio of the given type of material component consumption and necessary labor for constructing a power station, its technical standard, the technical standard of its components and the value relations between the compared and the reference power stations.

  17. Probabilistic reconstruction of internal exposure for nuclear power plant workers using air concentration measurements

    Air surveys, whole-body counting, bioassays or combination of these measurements can be utilized for purposes or assessing internal doses to determine compliance with occupational dose equivalent limits. Air sampling with a little support provided by whole body counting and/or bioassays was often relied on in dose calculations. The utility of air sampling for internal dose reconstruction is addressed in this paper through the probabilistic analysis of environmental factors and their impact on dose estimates. In this paper we attempt to reconstruct an internal dose due to inhalation of beta + gamma emitting radionuclides for a contractual electrician, Mr. X. The data available for reconstruction of internal dose for Mr. X was found to be highly variable and uncertain. Uncertainty describes a lack of knowledge about a parameter, this lack of knowledge theoretically can be reduced, e.g., if more measurements were to be taken (for example, estimated activities for alpha-emitting radionuclides are uncertain due to the influence of naturally-occurring alpha-emitters). Variability describes the existence of different values that represent different environmental conditions (for example, the air concentrations of radionuclides may vary over time because of the different tasks performed by workers in the area). Variability can not be reduced by additional data collection because the varying values reflect the variable nature of the environment, not a lack of data. The high variability in measured air concentrations in the restricted areas of a LWR nuclear power plant where he worked do not allow adequate reconstruction of his individual internal dose using deterministic methods and therefore probabilistic methods are desirable. The guidance for probabilistic assessment developed by the United States Environmental Protection Agency as well as recommendations of the National Council of Radiation Protection provide an adequate framework for probabilistic reconstruction of

  18. Licensing the First Nuclear Power Plant. INSAG-26. A report by the International Nuclear Safety Group

    nuclear power plant that is already licensed by an experienced regulator. Consequently, an option is to start development of national regulations by adopting or adapting regulations from a country that has licensed the same type of nuclear power plant. However, if the intention is to have an open technology selection process, care should be taken to establish a set of technology neutral regulations, such as by using the IAEA safety standards as the foundation. This set of technology neutral regulations can then be complemented by more design specific regulations after the technology is chosen. Since the development of technical competences requires considerable time, the regulatory body needs to plan for human resources development at a very early stage. As a first step, the essential competences required for the different phases of the nuclear power programme should be identified. Thereafter, formal training arrangements should be established between the regulatory body and one or more experienced regulators that have licensed a similar facility. This should include early interaction between senior managers of the two regulators followed by detailed training of selected staff who will form the technical core of the regulatory body. The regulatory body should also identify outside organizations that will act as its technical support organizations (TSOs) and should provide for conduct of nuclear safety R and D by these TSOs, including the appropriate research facilities and expertise. If additional nuclear power plants will be constructed in the new entrant country in the future, the new nuclear power plant units may not be of the same design as the first plant. This aspect should be kept in mind when developing both the licensing methodologies and staff. Regulatory staff can also obtain significant benefit from participation in international cooperation activities such as the Convention on Nuclear Safety, technical cooperation forums of regulatory bodies of countries

  19. Application of the 4th generation CT for diagnosis of pneumoconiosis

    The fourth generation CT (Toshiba TCT 900S) is the most sophisticated machine in the present, and it has high speed scan time (0.6, 1 and 2 sec.) and high resolution (0.35 mm). CT images taken by very short scan time have less movement factor of cardiac pulsation, and demonstrate clearly and sharply lung parenchymal or interstitial diseases using special filter function of FC 3 and FC 4. The CT images of sixty one cases of pneumoconiosis including profusion of 1/0, 1/1, 2/2 by the corresponding 1980 International Classification of Radiographs of Pneumoconioses were reviewed to estimate the correlation with plain chest roentgenograms. The detectability of bulla, blebs, pulmonary emphysema, pleural thickening, confluent nodules, calcified nodules and pneumothorax was higher than the chest roentgenogram. It is noticeable that visualization of small emphysematous lesion was far excellent on CT images. The discrepancy of these pathological findings between CT images and chest roenrgenogram was 61 % (37/61). From the three dimensional information, CT appears that it will make a large contribution to roentgenological interpretation. (author)

  20. Forensic botany II, DNA barcode for land plants: Which markers after the international agreement?

    Ferri, G; Corradini, B; Ferrari, F; Santunione, A L; Palazzoli, F; Alu', M

    2015-03-01

    The ambitious idea of using a short piece of DNA for large-scale species identification (DNA barcoding) is already a powerful tool for scientists and the application of this standard technique seems promising in a range of fields including forensic genetics. While DNA barcoding enjoyed a remarkable success for animal identification through cytochrome c oxidase I (COI) analysis, the attempts to identify a single barcode for plants remained a vain hope for a longtime. From the beginning, the Consortium for the Barcode of Life (CBOL) showed a lack of agreement on a core plant barcode, reflecting the diversity of viewpoints. Different research groups advocated various markers with divergent set of criteria until the recent publication by the CBOL-Plant Working Group. After a four-year effort, in 2009 the International Team concluded to agree on standard markers promoting a multilocus solution (rbcL and matK), with 70-75% of discrimination to the species level. In 2009 our group firstly proposed the broad application of DNA barcoding principles as a tool for identification of trace botanical evidence through the analysis of two chloroplast loci (trnH-psbA and trnL-trnF) in plant species belonging to local flora. Difficulties and drawbacks that were encountered included a poor coverage of species in specific databases and the lack of authenticated reference sequences for the selected markers. Successful preliminary results were obtained providing an approach to progressively identify unknown plant specimens to a given taxonomic rank, usable by any non-specialist botanist or in case of a shortage of taxonomic expertise. Now we considered mandatory to update and to compare our previous findings with the new selected plastid markers (matK+rbcL), taking into account forensic requirements. Features of all the four loci (the two previously analyzed trnH-psbA+trnL-trnF and matK+rbcL) were compared singly and in multilocus solutions to assess the most suitable combination for

  2. Application of the International Union of Radioecologists soil-to-plant database to Canadian settings

    The International Union of Radioecologists (IUR) has compiled a very large database of soil-to-plant transfer factors. These factors are ratios of the radionuclide concentrations in dry plants divided by the corresponding concentrations in dry soil to a specified depth or thickness. In this report the factors are called CR values, for concentration ratio. The CR values are empirical and are considered element-specific. The IUR database has a lot of data for Cs, Sr, Co, Pu and Np, and contains records for Am, Ce, Cm, I, La, Mn, Ni, Pb, Po, Ra, Ru, Sb, Tc, Th, U and Zn. Where there was a large amount of data, interpolation for ranges of soil conditions was possible. The tables presented here summarize the data in a way that should be immediately useful to modellers. Values are averaged for a number of crop types and species. Correction factors are developed to facilitate interpolation among soil conditions. The data tables in this report do not substitute for site-specific measurements, but they will provide data where measurement is impossible and give a background to check more recent data.

  3. Aging management of reactor internals and license renewal of US PWR plants

    Age-related degradation mechanisms of key components are subject to aging management review by utilities considering plant license renewal. The management of aging effects in PWR internals must be demonstrated as specified in the US NRC Standard Review. The US NRC staff has also issued a Generic Aging Lessons Learned (GALL) report that documents the staff's basis for determining when existing generic programs are adequate to manage aging without change and when existing generic programs should be augmented for license renewal. The EPRI Materials Reliability Program (MRP) has been conducting studies to develop technical bases and guidelines to support aging management of PWR internals, with a particular attention to utility License Renewal commitments. The strategic approach taken by the MRP includes: developing an overall aging management framework, defining degradation mechanism screening values, categorizing and ranking internals components based on screening, performing functionality analyses and safety evaluation, and developing inspection and evaluation guidelines associated with each category of components. Screening criteria are developed for the following potential internals degradation mechanisms: - Stress Corrosion Cracking [Excluding Irradiation Effects]; - Irradiation-Assisted Stress Corrosion Cracking; - Thermal Aging Embrittlement; - Irradiation Embrittlement; - Void Swelling; - Stress Relaxation and Creep [Irradiation-enhanced]; - Wear; - Fatigue. The ranking and categorization calls to bin internals components into four categories: - Category A: component items for which aging degradation significance is minimal and aging effects are below the screening criteria; - Category C: 'lead' component items for which aging degradation significance is high or moderate and aging effects are above screening levels; - Category B: component items above screening levels but are not 'lead' component items and aging degradation significance is moderate; - Category

  4. Environmental Radioactivity from Natural, Industrial and Military Sources. 4th Edition

    Merril Eisenbud's series of books on environmental radioactivity have long had a place on the bookshelves of those involved with the environmental aspects of radiation protection. They provide authoritative coverage of the subject including sources, transport mechanisms and effects. The first edition, published in 1963, was naturally mostly concerned with the effects of nuclear weapons testing in the atmosphere. The second edition, published in 1977, reflected the then expansive phase of nuclear power development worldwide and included an extensive treatment of the nuclear fuel cycle and its contributions to environmental radioactivity. In 1987 the third edition included coverage of the Three Mile Island accident and the Chernobyl accident against the background of cessation of new orders for nuclear plant in the United States. The fourth edition is a major revision with a lot of new material, and the welcome adoption of SI units throughout. The principal additions to the new edition are chapters on environmental surveillance, radiological assessment and dose reconstruction, and the remediation of contaminated sites; nothing has been lost from the extensive coverage of other topics in the third edition, whilst the text and bibliography have been revised and brought up to date. Earlier editions of the book have provided good summaries of accidents which have resulted in environmental contamination, and the updating here results in more extensive and up-to-date coverage of the Three Mile Island and Chernobyl accidents, including the more recent evidence of health effects from the latter, together with new sections on the Palomares nuclear weapons accident in Spain, the Mayak/Chelyabinsk complex in Russia, and the accidents involving lost gamma radiation sources in Juarez, Mexico and Goiania, Brazil. Both here and in the extensive coverage of contamination at the USDoE production sites the new edition reflects and benefits from the increased public availability of

  5. Actin gene identification from selected medicinal plants for their use as internal controls for gene expression studies

    Internal control genes are the constitutive genes which maintain the basic cellular functions and regularly express in both normal and stressed conditions in living organisms. They are used in normalization of gene expression studies in comparative analysis of target genes, as their expression remains comparatively unchanged in all varied conditions. Among internal control genes, actin is considered as a candidate gene for expression studies due to its vital role in shaping cytoskeleton and plant physiology. Unfortunately most of such knowledge is limited to only model plants or crops, not much is known about important medicinal plants. Therefore, we selected seven important medicinal wild plants for molecular identification of actin gene. We used gene specific primers designed from the conserved regions of several known orthologues or homologues of actin genes from other plants. The amplified products of 370-380 bp were sequenced and submitted to GeneBank after their confirmation using different bioinformatics tools. All the novel partial sequences of putative actin genes were submitted to GeneBank (Parthenium hysterophorus (KJ774023), Fagonia indica (KJ774024), Rhazya stricta (KJ774025), Whithania coagulans (KJ774026), Capparis decidua (KJ774027), Verbena officinalis (KJ774028) and Aerva javanica (KJ774029)). The comparisons of these partial sequences by Basic Local Alignment Search Tool (BLAST) and phylogenetic trees demonstrated high similarity with known actin genes of other plants. Our findings illustrated highly conserved nature of actin gene among these selected plants. These novel partial fragments of actin genes from these wild medicinal plants can be used as internal controls for future gene expression studies of these important plants after precise validations of their stable expression in such plants.

  6. Rare decays of the Z and the standard model, 4th generation, and beyond

    Several issues in rare decays of the Z are addressed. The rate for flavor-changing Z decay grows as the fourth power of the fermion masses internal to the quantum loop, and so offers a window to the existence of ultraheavy (m > MW) fermions. In the standard model, with three generations, BR(Z → bs) -7 and BR(Z→tc)-13. With four generations, BR(Z → bb4) may be as large as 10-5 if mb4 Z; and similarly for BR(Z → N4v), where N4 is the possibly heavy fourth generation neutrino. In supersymmetric and other two Higgs doublet models, BR(Z → tc) may be as large as 5 x 10-6 in the three generation scheme. With minimal supersymmetry, the reaction Z → Hγ is guaranteed to go, with a parameter-dependent branching ratio of 10-6±3. With mirror fermions or exotic E6 fermions, the branching ratios for Z → ct (70 GeV), Z → μτ, and Z → bb4 (70 GeV) are typically 10-4, 10-4, and 10-3 respectively, clearly measurable at LEP. Depending on unknown quark masses, the Z may mix with vector (b4 bar b4) and the W may mix with vector (t bar b) or (t bar s). CP violating asymmetries in flavor-changing Z decay are immeasurably small in the standard model, but may be large in supersymmetric and other nonstandard models. 28 refs

    Several issues in rare decays of the Z are addressed. The rate for flavor-changing Z decay grows as the fourth power of the fermion masses internal to the quantum loop, and so offers a window to the existence of ultraheavy (m > M{sub W}) fermions. In the standard model, with three generations, BR(Z {yields} bs) < 10{sup -7} and BR(Z{yields}tc)<10{sup -13}. With four generations, BR(Z {yields} bb{sub 4}) may be as large as 10{sup -5} if m{sub b4} < M{sub Z}; and similarly for BR(Z {yields} N{sub 4}v), where N{sub 4} is the possibly heavy fourth generation neutrino. In supersymmetric and other two Higgs doublet models, BR(Z {yields} tc) may be as large as 5 {times} 10{sup -6} in the three generation scheme. With minimal supersymmetry, the reaction Z {yields} H{gamma} is guaranteed to go, with a parameter-dependent branching ratio of 10{sup -6 {plus minus} 3}. With mirror fermions or exotic E{sub 6} fermions, the branching ratios for Z {yields} ct (70 GeV), Z {yields} {mu}{tau}, and Z {yields} bb{sub 4} (70 GeV) are typically 10{sup -4}, 10{sup -4}, and 10{sup -3} respectively, clearly measurable at LEP. Depending on unknown quark masses, the Z may mix with vector (b{sub 4}{bar b}{sub 4}) and the W may mix with vector (t{bar b}) or (t{bar s}). CP violating asymmetries in flavor-changing Z decay are immeasurably small in the standard model, but may be large in supersymmetric and other nonstandard models. 28 refs.

    The reactor neutrino and gallium anomalies can be tested with a 3-4 PBq (75-100 kCi scale) 144Ce-144Pr antineutrino beta-source deployed at the center or next to a large low-background liquid scintillator detector. The antineutrino generator will be produced by the Russian reprocessing plant PA Mayak as early as 2014, transported to Japan, and deployed in the Kamioka Liquid Scintillator Anti-Neutrino Detector (KamLAND) as early as 2015. KamLAND's 13 m diameter target volume provides a suitable environment to measure the energy and position dependence of the detected neutrino flux. A characteristic oscillation pattern would be visible for a baseline of about 10 m or less, providing a very clean signal of neutrino disappearance into a yet-unknown, sterile neutrino state. This will provide a comprehensive test of the electron dissaperance neutrino anomalies and could lead to the discovery of a 4th neutrino state for Delta_m^2 > 0.1 eV^2 and sin^2(2theta) > 0.05.

    Ionizing radiation (IR) is a known mutagen responsible for causing DNA strand breaks in all living organisms. Strand breaks thus created can be repaired by different mechanisms, including homologous recombination (HR), one of the key mechanisms maintaining genome stability [A. Britt, DNA damage and repair in plants, Annu. Rev. Plant. Phys. Plant Mol. Biol., 45 (1996) 75-100; H. Puchta, B. Hohn, From centiMorgans to basepairs: homologous recombination in plants, Trends Plant Sci., 1 (1996) 340-348.]. Acute or chronic exposure to IR may have different influences on the genome integrity. Although in a radioactively contaminated environment plants are mostly exposed to chronic pollution, evaluation of both kinds of influences is important. Estimation of the frequency of HR in the exposed plants may serve as an indication of genome stability. We used previously generated Arabidopsis thaliana and Nicotiana tabacum plants, transgenic for non-active versions of the {beta}-glucoronidase gene (uidA) [P. Swoboda, S. Gal, B. Hohn, H. Puchta, Intrachromosomal homologous recombination in whole plants, EMBO J., 13 (1994) 484-489; H. Puchta, P. Swoboda, B. Hohn, Induction of homologous DNA recombination in whole plants, Plant, 7 (1995) 203-210.] serving as a recombination substrate, to study the influence of acute and chronic exposure to IR on the level of HR as example of genome stability in plants. Exposure of seeds and seedlings to 0.1 to 10.0 Gy 60Co resulted in increased HR frequency, although the effect was more pronounced in seedlings. For the study of the influence of chronic exposure to IR, plants were grown on two chemically different types of soils, each artificially contaminated with equal amounts of 137Cs. We observed a strong and significant correlation between the frequency of HR in plants, the radioactivity of the soil samples and the doses of radiation absorbed by plants (in all cases r0.9, n=6, P<0.05).

    The fourth edition of the National Meeting on Chaos, Complex Systems and Time Series (NMCCSTS4), or in Spanish 4a. Reunión Nacional de Caos, Sistemas Complejos y Series de Tiempo, was held from 29 November to 2 December 2011 in the University of Veracruz (Universidad Veracruzana), Campus Xalapa, at Xalapa Veracruz, México, in the beautiful House of the Lake (Casa del Lago), a late XIX century former textile factory situated in the edge of an also ancient former dam, currently a park containing three small lakes, very emblematic of Xalapa, City, the capital of the state of Veracruz, México. The previous editions of this meeting, were held in Mérida (2006), Pachuca (2008) and Puebla (2009). A clear uptrend is observed in the number of participants in this academic event from all Universities of México and abroad, going from about 15 participants in the first meeting to more than 90 in the last one. On this occasion, about 90 participants from three countries attended our event, where 29 papers (10 master lectures from top recognized national and international leaders in the fields of complexity, and 19 invited papers), one course for students and 42 posters were presented. A look at the scientific program of the NMCCSTS4, allows us to appreciate the wide range of topics and recent advances that were covered during our event; topics and recent results in the areas of biology, econophysics, sociophysics, genomics and bioinformatics, complex networks, thermodynamics, etc, were presented and discussed rigorously in a friendly, dynamical and informal atmosphere. Also, on this occasion, we celebrated Professor Miguel Angel Jiménez Montaño, for his very distinguished academic career throughout more that 50 years and as a founding member of the Faculty of Physics and AI of University of Veracruz. Prizes were awarded for the best poster presentations. The winner was Porfirio Toledo, from Faculty of Mathematics, University of Veracruz (Game theory to characterize

  15. Nuclear power plant conference 2010 (NPC 2010): International conference on water chemistry of nuclear reactor systems and 8th International radiolysis, electrochemistry and materials performance workshop

    The Nuclear Plant Chemistry Conference was held in Quebec City, Quebec, Canada on October 3-7, 2010. It was hosted by the Canadian Nuclear Society and was held in Canada for the first time. This international event hosted over 300 attendees, two thirds from outside of Canada, mostly from Europe and and Far East. The conference is formally known as the International Conference on Water Chemistry of Nuclear Reactor Systems and is the 15th of a series that began in 1977 in Bournemouth, UK. The conference focussed on the latest developments in the science and technology of water chemistry control in nuclear reactor systems. Utility scientists, engineers and operations people met their counterparts from research institutes, service organizations and universities to address the challenges of chemistry control and degradation management of their complex and costly plants for the many decades that they are expected to operate. Following the four day conference, the 8th International Radiolysis, Electrochemistry and Materials Performance Workshop was held as associated, but otherwise free-standing event on Friday, October 8, 2010. It was also well attended and the primary focus was the effect of radiation on corrosion. When asked about the importance of chemistry in operating nuclear power plants, the primary organizers summarized it in the following statement: 'Once a nuclear plant is in operation, chemistry improvement is the only way to increase the longevity of the plant and its equipment'. The organisers of the 2010 Workshop and the NPC 2010 conference decided that these two events would be held consecutively, as previous, but for the first time the organization and registration would be shared, which proved to be a winning combination by the attendance.

  16. Evaluation of soil to tea plant elemental correlation using k0 based internal monostandard neutron activation analysis

    The k0-based internal monostandard neutron activation analysis (IM-NAA) using Sc as monostandard was employed for the determination of multielemental concentrations in soil and tea plants from tea gardens of Assam, Darjeeling and Kangra, India. A total of 17 tea leaves and corresponding soils of tea plants were analyzed by IM-NAA using neutrons from Dhruva research reactor and high resolution gamma ray spectrometry. Concentrations of nine elements viz. Ce, Co, Cr, Cs, Fe, Rb, Sc, Th and Zn were determined and used to evaluate elemental transfer factors from soil to tea plant and thus for soil-plant elemental correlation studies. High degree of soil to tea plant elemental correlation was observed with Pearson correlation coefficient values (p- value) in the range 0.6-0.9. (author)

    Medical standby is the provision of emergency medical care and first aid for participants and/or spectators in a pre-planned event. This article describes the framework and the demographics of a medical standby at the 4th National Youth Camping and Motivation Program in Pasir Puteh, Kelantan from 30th July until the 3rd August 2004. The framework of the medical team is described based on the work process of any medical stand by. A medical encounter form was created for the medical standby defining the type of case seen (medical or trauma), name, age, race and diagnosis of the patient. We concluded that interagency collaboration during the initial planning and during the event itself is needed to ensure the smooth running of the medical standby. Most of the medical encounters were minor illnesses which are similar to previous studies and there was no case transferred to the hospital during that period. PMID:22589590

  3. Results of the independent verification of radiological remedial action at 148 East 4th South Street, Monticello, Utah (MS00087)

    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 1984, UNC Geotech, the remedial action contractor designated by DOE, performed remedial action on the vicinity property at 148 East 4th South 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

  6. Burn-out and isotope structure of nuclear fuel in lavas of 4-th unit Ch NPP

    In article the question on legitimacy of application of the relation 134Cs/137Cs for definition of a degree of burn-out of the fulfilled nuclear fuel in lava like fuel contained mass (LFCM) broken down of 4-th unit ChNPP is considered. This method is compared to this purpose with other independent methods of account of burn-out. In particular, precision the analysis of the chosen samples LFCM was carried out with use of a method isotope dilution with alpha- and mass-spectrometer measurement of the isotope relations in plutonium and uranium. Is shown, that use of cesium relation for calculation of burn-out is quite allowable. The man powers at definition of this value received by results a gamma-spectrometric analysis of samples, do not go in any comparison with expenditure of labour of all other methods. 6 refs., 10 tab., 2 figs

    Stallard, G.S.; Deschaine, R. [Black and Veatch (United States)

    2008-05-15

    The WEC Committee on the Performance of Generating Plant (PGP) has been collecting and analysing power plant performance statistics worldwide for more than 30 years and has produced regular reports, which include examples of advanced techniques and methods for improving power plant performance through benchmarking. A series of reports from the various working groups was issued in 2008. This reference presents the results of Working Group 1 (WG1). WG1's primary focus is to analyse the best ways to measure, evaluate, and apply power plant performance and availability data to promote plant performance improvements worldwide. The paper explores the specific work activities of 2004-2007 to extend traditional analysis and benchmarking frameworks. It is divided into two major topics: Overview of current electric supply industry issues/trends; and, Technical Methods/Tools to evaluate performance in today's ESI.

  8. A Comparison of international regulatory organizations and licensing procedures for new nuclear power plants

    This paper considers measures needed to license new nuclear power plants efficiently. We base our analysis on the international standards and the comparison of the national regulatory and licensing framework of seven countries (Canada, France, Germany, Japan, Switzerland, the United-Kingdom and the United States of America). We split the review into the organization of regulatory responsibilities and the licensing process. We propose a set of aspects that should be incorporated into national solutions. We advise the creation of an independent specialized regulator. It should consult extensively other expert bodies as a way to ensure the soundness of its decisions. Based on the regulator's recommendations the government should issue the licenses, possibly after parliamentary approval. The licensing process should be split into different fixed steps like: design, site, construction, pre-commissioning tests and operation. Public should be first consulted on a large-scale during the siting process and then consulted over the lifetime of the project at each license renewal. Legislators should ensure that a reduced, up-to-date and coherent set of laws covers each aspect of nuclear safety. We suggest that no more than 10 laws should be in force

  9. The internal transcribed spacer 2 exhibits a common secondary structure in green algae and flowering plants.

    Mai, J C; Coleman, A W

    1997-03-01

    Sequences of the Internal Transcribed Spacer 2 (ITS-2) regions of the nuclear rDNA repeats from 111 organisms of the family Volvocaceae (Chlorophyta) and unicellular organisms of the Volvocales, including Chlamydomonas reinhardtii, were determined. The use of thermodynamic energy optimization to generate secondary structures and phylogenetic comparative analysis of the spacer regions revealed a common secondary structure that is conserved despite wide intra- and interfamilial primary sequence divergence. The existence of this conserved higher-order structure is supported by the presence of numerous compensating basepair changes as well as by an evolutionary history of insertions and deletions that nevertheless maintains major aspects of the overall structure. Furthermore, this general structure is preserved across broad phylogenetic lines, as it is observed in the ITS-2s of other chlorophytes, including flowering plants; previous reports of common ITS-2 secondary structures in other eukaryotes were restricted to the order level. The reported ITS-2 structure possesses important conserved structural motifs which may help to mediate cleavages in the ITS-2 that occur during rRNA transcript processing. Their recognition can guide further studies of eukaryotic rRNA processing, and their application to sequence alignments may contribute significantly to the value of ITS-2 sequences in phylogenetic analyses at several taxonomic levels, but particularly in characterizing populations and species.

  10. 4th Optimization Day

    Eberhard, Andrew; Ralph, Daniel; Glover, Barney M

    1999-01-01

    Although the monograph Progress in Optimization I: Contributions from Aus­ tralasia grew from the idea of publishing a proceedings of the Fourth Optimiza­ tion Day, held in July 1997 at the Royal Melbourne Institute of Technology, the focus soon changed to a refereed volume in optimization. The intention is to publish a similar book annually, following each Optimization Day. The idea of having an annual Optimization Day was conceived by Barney Glover; the first of these Optimization Days was held in 1994 at the University of Ballarat. Barney hoped that such a yearly event would bring together the many, but widely dispersed, researchers in Australia who were publishing in optimization and related areas such as control. The first Optimization Day event was followed by similar conferences at The University of New South Wales (1995), The University of Melbourne (1996), the Royal Melbourne Institute of Technology (1997), and The University of Western Australia (1998). The 1999 conference will return to Ballarat ...

    Friedlander, Eric; Jahren, Björn; Østvær, Paul

    2009-01-01

    The 2007 Abel Symposium took place at the University of Oslo in August 2007. The goal of the symposium was to bring together mathematicians whose research efforts have led to recent advances in algebraic geometry, algebraic K-theory, algebraic topology, and mathematical physics. A common theme of this symposium was the development of new perspectives and new constructions with a categorical flavor. As the lectures at the symposium and the papers of this volume demonstrate, these perspectives and constructions have enabled a broadening of vistas, a synergy between once-differentiated subjects, and solutions to mathematical problems both old and new.

  13. The choice of internal characteristics of a gaseous diffusion plant. Theoretical aspects: decomposition and multi-level optimization

    The optimum choice of all the internal characteristics of a gaseous diffusion plant for minimizing the enrichment cost, is a large scale problem. The mathematical analysis of the model simulating such a plant has led to the observation of a hierarchical structure, introducing a method of decomposition. The multi-level approach focuses successively on three levels: the stage, the cascade, the plant. Then each level can be solved specifically, using an algorithm properly suited to its characteristics. The problem is to coordinate properly the sub-optimizations by using coordination variables. This method has effectively been used for years as a tool for the decision-makers, in association with the experimental and development work, and the industrial analysis, furnishing the current technical and economical data at the moment of the decision: plant capacity, component performances, economical prices and trends

  15. [A development of Byzantine Christian charities during the 4(th)-7(th) centuries and the birth of the hospital].

    Nam, Sung Hyun

    2015-04-01

    This study aims to examine the beginning and the development of Christian Charities during the 4(th)-6(th) centuries which would eventually result in the birth of the hospital in modern sense in the first half of the 7(th) century. For this purpose, I looked carefully into various primary sources concerning the early Christian institutions for the poor and the sick. Above all, it's proper to note that the first xenodocheion where hospitality was combined with a systematic caring, is concerned with the Trinitarian debate of the 4(th) century. In 356, Eustathios, one of the leaders of homoiousios group, established xenodocheion to care for the sick and the lepers in Sebaste of Armenia, whereas his opponent Aetios, doctor and leader of the heteroousios party, was reckoned to have combined the medical treatment with his clerical activities. Then, Basil of Caesarea, disciple of Eustathios of Sebaste, also founded in 372 a magnificent benevolent complex named 'Basileias' after its founder. I scrupulously analysed several contemporary materials mentioning the charitable institution of Caesarea which was called alternatively katagogia, ptochotropheion, xenodocheion. John Chrysostome also founded several nosokomeia in Constantinople at the end of the 4(th) century and the beginning of the 5(th) century. Apparently, the contemporary sources mention that doctors existed for these Charities, but there is no sufficient proof that these 'Christian Hospitals,' Basileias or nosokomeia of Constantinople were hospitals in modern sense. Imperial constitutions began to mention ptochotropheion, xenodocheion and orphanotropheion since the second half of the 5(th) century and then some Justinian laws evoked nosokomium, brephotrophia, gerontocomia. These laws reveal that 'Christian Hospitals' were well clarified and deeply rooted in Byzantine society already in these periods. And then, new benevolent institutions emerged in the 6(th) century: nosokomeia for a specific class and

  16. Protection against internal hazards other than fires and explosions in the design of nuclear power plants. Safety guide

    Although, regulating nuclear and radiation safety is a national responsibility, and many Member States have decided to adopt the IAEA' safety standards for use in their national regulations. For the Contracting Parties to the various international safety conventions, IAEA standards provide a consistent, reliable means of ensuring the effective fulfilment of obligations under the conventions. This Safety Guide, which supplements the Safety Requirements publication on the Safety of Nuclear Power Plants Design, was prepared under the IAEA's programme for establishing Safety Requirements and Safety Guides applicable to land based stationary thermal neutron nuclear power plants. Examples provided in this Safety Guide pertain to light water reactor plants; however, the recommendations provided in this Safety Guide are generally applicable to other types of plant with thermal neutron reactors. 1.2. This Safety Guide supersedes the Safety Guide on Protection against Internally Generated Missiles and their Secondary Effects in Nuclear Power Plants, published in 1980 as Safety Series No. 50-SG-D4. This Safety Guide discusses postulated initiating events (PIEs) that may occur in the different operational states of the plant. It introduces the probabilistic and deterministic approaches for reviewing the following: (a) PIEs, postulated in a deterministic approach, and their probability of occurrence, which is estimated in the probabilistic approach; (b) The potential for or probability of structures, systems and components (SSCs) being affected; (c) The potential for or probability of damaging consequences; (d) The overall assessment of consequences, to make judgements on their acceptability. This revision principally consists of updating the technical content and the discussion. In the revision process, it was decided to extend the scope to cover internal hazards in general (other than fires and explosions, which are covered in a separate Safety Guide

  17. Tenth meeting of the International Working Group on Nuclear Power Plant Control and Instrumentation, Vienna, 3-5 March 1986

    The meeting of the International Working Group on Nuclear Power Plant Control and Instrumentation (IWG-NPPCI) was organized in order to summarize operating experience of NPP control systems, gain a general overview of activities in development of modern control systems and receive recommendations on the further directions and particular measures within the Agency's programme. The papers and discussions mostly dealt with practical experience and described actual problems encountered. Emphasis was placed on the technical, industrial and economic aspects of the introduction of modern, highly automated control systems and on the improvement of plant availability and safety. A separate abstract was prepared for each of the 20 presentations of the meeting

  18. Internal safeguards for centrifuge enrichment plants. Concepts and procedures for safeguards and the international Hexapartite Safeguards Project (HSP)

    These papers were elaborated partly as annexes to the HSP and partly within a BMFT research programme. Chapter 2 shows how the HSP is to be proceeded with and describes the inspection activities agreed upon. Chapters 3 and 4 deal with the nuclear materials accountancy in a uranium enrichment plant; the conception of a computer-aided safeguards system (chapter 4) can only be given in condensed form owing to its size. Chapter 5 is a general evaluation of now available NDA and C/S systems whereas chapters 6 and 7 indicate fields of application for specialized technologies. Even though the inspection model agreed upon as a result of the HSP discussions is to include limited frequency unannounced access to separating rooms for inspectors, theoretical and experimental studies have been carried out in the meantime assuming the non-access model.

  19. Heavy Bino Dark Matter and Collider Signals in the MSSM with Vector-like 4th-Generation Particles

    Abdullah, Mohammad; Iwamoto, Sho; Lillard, Benjamin

    2016-01-01

    MSSM4G models, in which the minimal supersymmetric standard model is extended to include vector-like copies of standard model particles, are promising possibilities for weak-scale supersymmetry. In particular, two models, called QUE and QDEE, realize the major virtues of supersymmetry (naturalness consistent with the 125 GeV Higgs boson, gauge coupling unification, and thermal relic neutralino dark matter) without the need for fine-tuned relations between particle masses. We determine the implications of these models for dark matter and collider searches. The QUE and QDEE models revive the possibility of heavy Bino dark matter with mass in the range 300-700 GeV, which is not usually considered. Dark matter direct detection cross sections are typically below current limits, but are naturally expected above the neutrino floor and may be seen at next-generation experiments. Indirect detection prospects are bright at the Cherenkov Telescope Array, provided the 4th-generation leptons have mass above 350 GeV or dec...

    2012-08-01

    Full Text Available Knowledge is the driving motor of knowledge-oriented development and paying attention to it will have an ever-increasing role in the growth of societies. Today, gaining knowledge related to work is not sufficient at all. Produced information and key knowledge in the organization must be exchanged and shared with colleagues that need such knowledge in order to better performing of their working tasks in the organization so that the organization could achieve stable competitive advantage. Islamic Azad University must be more active in the field of learner organization and knowledge management given to its knowledge nature. Recognizing the effective factors on knowledge exchange and implementation of knowledge management process and main factors of its success in Islamic Azad University are objectives of the present survey. One-hundred eighty one (181 persons were selected among employees of Islamic Azad University located at 4th zone in this survey. Research hypotheses were tested by SPSS software and these results were obtained: 1- There is a significant relationship between informal conversations of employees and their confidence level with employees' knowledge sharing. 2- Using knowledge sharing in the standards of job promotion and reward won't be leaded to encourage employees to exchange their knowledge with others.

  1. Communicating Science to Impact Learning? A Phenomenological Inquiry into 4th and 5th Graders' Perceptions of Science Information Sources

    Gelmez Burakgazi, Sevinc; Yildirim, Ali; Weeth Feinstein, Noah

    2016-04-01

    Rooted in science education and science communication studies, this study examines 4th and 5th grade students' perceptions of science information sources (SIS) and their use in communicating science to students. It combines situated learning theory with uses and gratifications theory in a qualitative phenomenological analysis. Data were gathered through classroom observations and interviews in four Turkish elementary schools. Focus group interviews with 47 students and individual interviews with 17 teachers and 10 parents were conducted. Participants identified a wide range of SIS, including TV, magazines, newspapers, internet, peers, teachers, families, science centers/museums, science exhibitions, textbooks, science books, and science camps. Students reported using various SIS in school-based and non-school contexts to satisfy their cognitive, affective, personal, and social integrative needs. SIS were used for science courses, homework/project assignments, examination/test preparations, and individual science-related research. Students assessed SIS in terms of the perceived accessibility of the sources, the quality of the content, and the content presentation. In particular, some sources such as teachers, families, TV, science magazines, textbooks, and science centers/museums ("directive sources") predictably led students to other sources such as teachers, families, internet, and science books ("directed sources"). A small number of sources crossed context boundaries, being useful in both school and out. Results shed light on the connection between science education and science communication in terms of promoting science learning.

  2. A study of personality factors and interaction in 4th-year dental students and their teachers.

    Watts, T L; Millard, L

    1997-02-01

    No previous investigation has considered dental student and teaching staff opinions on their relationship with each other. In a day when students are increasingly asked for feedback on the quality of teaching by staff, such investigations are of particular interest. This exploratory study was designed to compare the personality characteristics of a clinical year of dental students with those of the teaching staff they most frequently encountered, and to investigate these factors for possible associations with the quality of perceived teaching-learning interaction between the 2 groups. A complete 4th year of dental students (n = 87), and those teachers whom they met regularly (n = 80), were asked to participate. Subjects completed a form of the Myers-Briggs personality questionnaire simplified for use in education, and were asked to assess their relationship with persons in the other group. All the students and 75% of the staff, after follow-up, returned usable data. There was close similarity between staff and student personality profiles, and perception of working relationships by both groups was largely independent of personality factors and temperament. There were differences in staff perception of their relationship with extrovert and introvert students. Students showed minor differences in their perception of staff relationships with respect to two other personality factors. These findings indicate a substantial similarity between staff and students, and suggest a mature and stable relationship between people in the 2 groups. PMID:9567907

  3. Factors related to the reading comprehension skills of 4th grade students according to data of PIRLS 2001 Turkey

    Full Text Available Central to a nation’s pursuit of its social, political, and economic goals is a literate and well-educated population. Furthermore, the ability to read is fundamental to individual intellectual development and personal growth. Knowledge about how well students can read, together with information about which policy-related factors are implicated in understanding reading achievement, can provide policy makers and researchers worldwide with insights into how to improve literacy and reading achievement. The aim of this study is to model the factors related to the reading comprehension skills of 4th grade students according to the PIRLS 2001 data. A model has been proposed by making use of the student, teacher, family questionnaires used in the PIRLS 2001 study, with variables considered as related to the reading comprehension skills of students, in addition to taking into account the related literature. A structural equation model has been used in order to define the relation among the students’ reading comprehension skills and the specifications of the family, school, teacher and student. Taking into account the regression equation obtained by the result of the structural equation model analysis, it is seen that the determination coefficient is 0.51. This shows that 0.51 of reading comprehension skills of the Turkish students taking place in the PIRLS study can be explained by the features of family, school, teacher, and student, as specified for this study.

  4. Quality of education predicts performance on the Wide Range Achievement Test-4th Edition Word Reading subtest.

    Sayegh, Philip; Arentoft, Alyssa; Thaler, Nicholas S; Dean, Andy C; Thames, April D

    2014-12-01

    The current study examined whether self-rated education quality predicts Wide Range Achievement Test-4th Edition (WRAT-4) Word Reading subtest and neurocognitive performance, and aimed to establish this subtest's construct validity as an educational quality measure. In a community-based adult sample (N = 106), we tested whether education quality both increased the prediction of Word Reading scores beyond demographic variables and predicted global neurocognitive functioning after adjusting for WRAT-4. As expected, race/ethnicity and education predicted WRAT-4 reading performance. Hierarchical regression revealed that when including education quality, the amount of WRAT-4's explained variance increased significantly, with race/ethnicity and both education quality and years as significant predictors. Finally, WRAT-4 scores, but not education quality, predicted neurocognitive performance. Results support WRAT-4 Word Reading as a valid proxy measure for education quality and a key predictor of neurocognitive performance. Future research should examine these findings in larger, more diverse samples to determine their robust nature. PMID:25404004

  5. Modeling of Synergy Between 4th and 6th Harmonic Absorptions of Fast Waves on Injected Beams in DIII-D Tokamak

    In recent moderate to high harmonic fast wave heating and current drive experiments in DIII-D, a synergy effect was observed when the 6th harmonic 90 MHz fast wave power is applied to the plasma preheated by neutral beams and the 4th harmonic 60 MHz fast wave. In this paper, we investigate how the synergy can occur using ORBIT-RF coupled with AORSA. Preliminary simulations suggest that damping of 4th harmonic FW on beam ions accelerates them above the injection energy, which may allow significant damping of 6th harmonic FW on beam ion tails to produce synergy.

  7. An international benchmark on safety review practices at nuclear power plants

    A benchmarking exercise on safety review practices at nuclear power plants in Finland, Sweden and the United Kingdom has been carried out. In the exercise a comparison was made between documented practices at the Forsmark, Hinkley Point A and Olkiluoto nuclear power plants. In addition a total of 28 persons at FKA, Magnox and TVO were interviewed on their views on the efficiency of the plant modification processes in the later half of 1997. One specific example of a plant modification was selected from each of the nuclear power plant sites to provide a basis for the comparison. The report gives an account of the methodology used, a description of the plant modification projects, impressions from the interviews, potential problem areas and suggestions for possible improvements.

    2003-01-01

    In this paper we analyse the interactions between fire severity ( plant damage) and plant regeneration after fire by means of remote sensing imagery and a field fire severity map. A severity map was constructed over a large fire ( 2692 ha) occurring in July 1994 in the Barcelona province (north-east of Spain). Seven severity classes were assigned to the apparent plant damage as a function of burning intensity. Several Landsat TM and MSS images from dates immediately before and after the fire ...

  9. Information technology impact on nuclear power plant documentation. Report prepared within the framework of the International Working Group on Nuclear Power Plant Control and Instrumentation

    As the majority of the nuclear power plants (NPPs) in the world were designed and constructed about twenty to forty years ago, these older power plants may have shortcomings in documentation on construction, commissioning, operations, maintenance, or decommissioning. Therefore, facility documentation does not always reflect actual plant status after years of plant operation, modification, and maintenance. To deal with these shortcomings, computer and information technologies that provide sophisticated and modern design tools as well as information processing and storage facilities can offer dramatic innovation from paper-centric documentation towards data-centric documentation. This report addresses all aspects of documentation associated with various life-cycle phases of NPPs and the information technology (IT) that are relevant to the documentation process. It also provides a guide for planning, designing, and executing an IT documentation project. Examples are given to demonstrate successful implementations at plants. Finally, it discusses the issues related to the application of the IT in NPPs and the trends for applications of the IT at NPPs as well as the technology itself. It is recognized that this can also improve configuration management. reliability of data, quality of personnel work, and ultimately plant performance reliability and safety. The aspects of using the IT for NPP documentation are closely related to configuration management at NPPs. The report consists of nine sections, a reference section, and five additional appendices. The development of this report which was initiated by the IAEA International Working Group on Nuclear Power Plant Control and Instrumentation (IWG-NPPCI). It is the result of a series of consultants meetings held by the IAEA in Vienna (October 1999, November 2000). It was prepared with the participation and contributions of experts from Canada, Germany, Norway, Sweden, and the United States of America. In addition, a

  10. The MIT international program for enhanced nuclear power plant safety: Organization and management in the nuclear power industry

    This document is a report of the meeting between the Nuclear Power Industry Executives Advisory Panel and the Organization and Management Study Group of the MIT International Program for Enhanced Nuclear Power Plant Safety. At the first meeting, 16 representatives from utilities in four countries and 11 MIT faculty and staff explored mutual interests in order to guide future efforts. Roundtable groups selected four topics for further discussion: (1) compliance and autonomy, (2) cost control and safety, (3) plant aging and workforce changes, and (4) cross-functional complexity. The MIT researchers discussed their proposed research design featuring three studies conducted in utilities that operate multiple plants, one at each utility identified as a good performer, and a second at a utility needing improvement. These three studies were: (1) outage planning and implementation, (2) performance improvement as a problem solving process, and (3) ways to characterize the organizational knowledge at a utility and its relationship to performance enhancement

  11. Internal radiation dose of KURRI volunteers working at evacuation shelters after TEPCO's Fukushima Daiichi nuclear power plant accident

    We report the radiation doses encountered by 59 Kyoto University Research Reactor Institute (KURRI) staff members who had been dispatched to screen refugees for radiation at emergency evacuation sites 45-80 km from the Tokyo Electric Power Co.'s (TEPCO's) Fukushima Daiichi nuclear power plant. From March 20 to April 30, 2011, 42 members in teams consisting of 2-4 staff members were dispatched 15 times to 7 emergency evacuation sites located 45-80 km from the power plant to examine the radioactive contamination affecting refugees. Continuously, from May 10 to May 23, 2011, 17 members in teams consisting of 2-5 staff members were dispatched 6 times to Fukushima Prefecture to establish the Kyoto University Radiation Mapping (KURAMA) system. Internal burdens of radioactive nuclides were estimated using a whole-body counter consisting of an iron room, NaI (Tl) scintillation detectors, and a digital multichannel analyzer (MCA7600; Seiko EG and G). The calibration of the whole-body counter and the conversion of the measured body burden to the committed effective dose by internal exposure were carried out in accordance with the Nuclear Safety Research Association (NSRA) technical manual. The external radiation dose to each staff member was measured using a personal dosimeter. The first dispatched team showed 1300-1929 Bq of internal radiation activity from cesium (including 137Cs and 134Cs) and 48-118 Bq of 131I. The internal doses of four members of the first team were estimated to be 24-39 μSv. The doses from internal exposure were almost similar to the cumulative external doses for the dispatch period (March 20-22, 2011) when the radiation plumes following the explosions of Units 1 and 3 in TEPCO's Fukushima Daiichi nuclear plant had diffused around Fukushima City. The external radiation doses of members dispatched after the second team had decreased from one-third to less than one-tenth of the external doses of the first dispatched team. The internal radiation doses

  12. Assessment and management of ageing of major nuclear power plant components important to safety: PWR vessel internals

    At present, there are over four hundred operational nuclear power plants (NPPs) in IAEA Member States. Operating experience has shown that ineffective control of the ageing degradation of the major NPP components (e.g. caused by unanticipated phenomena and by operating, maintenance or manufacturing errors) can jeopardize plant safety and also plant life. Ageing in these NPPs must be therefore effectively managed to ensure the availability of design functions throughout the plant service life. From the safety perspective, this means controlling within acceptable limits the ageing degradation and wear-out of plant components important to safety so that adequate safety margins remain, i.e. integrity and functional capability in excess of normal operating requirements. This TECDOC is one in a series of reports on the assessment and management of ageing of the major NPP components important to safety. The reports are based on experience and practices of NPP operators, regulators, designers, manufacturers, and technical support organizations and a widely accepted Methodology for the Management of Ageing of NPP Components Important to Safety, which was issued by the IAEA in 1992. The current practices for the assessment of safety margins (fitness-for-service) and the inspection, monitoring and mitigation of ageing degradation of selected components of Canada deuterium-uranium (CANDU) reactors, boiling water reactors (BWRs), pressurized water reactors (PWRs), and water moderated, water cooled energy reactors (WWERs) are documented in the reports. These practices are intended to help all involved directly and indirectly in ensuring the safe operation of NPPs, and to provide a common technical basis for dialogue between plant operators and regulators when dealing with age related licensing issues. The guidance reports are directed at technical experts from NPPs and from regulatory, plant design, manufacturing and technical support organizations dealing with specific plant

    2016-03-01

    Full Text Available The use of medicinal plants plays a major role in the primary health care of animals in South Africa. A survey was conducted to document medicinal plants used to control parasites in goats in Kwezi and Ntambethemba villages in the Eastern Cape Province, South Africa. Information from 50 farmers and 3 herbalists was obtained through the use of a structured questionnaire, and a snowball sampling technique was used to identify key informants. The obtained data were analysed using PROC FREQ of SAS (2003, and fidelity level values were determined to estimate the healing potential of the mentioned plants. The survey revealed nine plant species belonging to eight families that were used to control parasites in goats. Asphodelaceae (22.22% was the most frequently used plant family. Leaves were the most used plant parts, constituting 60.38%. They were prepared either as infusions or decoctions of single plants or in mixtures. Aloe ferox, Acokanthera oppositifolia and Elephantorrhiza elephantina were the plants having the highest fidelity level for their use to control parasites, each scoring 100%, followed by Albuca setosa (83.33%. The study revealed low knowledge about ethnoveterinary medicine in the study area. It also revealed that information on ethno-veterinary medicine in this area is mostly confined to older people and there is danger that this knowledge can be lost before being passed on to other generations. Therefore, there is an urgent need to document information on these plant species so that the future generation can benefit. Further investigation should be carried out to validate the efficacy and safety of the above-mentioned plants so as to provide cheap alternative ways of controlling parasites.Keywords: ailments; ethno-veterinary practices; small ruminant; traditional medicine

  20. Assessment and management of ageing of major nuclear power plant components important to safety: PWR vessel internals: 2007 update

    At present, there are over four hundred operational nuclear power plants (NPPs) in IAEA Member States. Operating experience has shown that effective control of the ageing degradation of the major NPP components (e.g. caused by unanticipated phenomena and by operating, maintenance or manufacturing errors) is one of the most important issues for plant safety and also plant life. Ageing in these NPPs must be therefore effectively managed to ensure the availability of design functions throughout the plant service life. From the safety perspective, this means controlling within acceptable limits the ageing degradation and wearout of plant components important to safety so that adequate safety margins remain, i.e. integrity and functional capability in excess of normal operating requirements. IAEA-TECDOC-1119 documents ageing assessment and management practices for PWR Reactor Vessel Internals (RVIs) that were current at the time of its finalization in 1997-1998. Safety significant operating events have occurred since the finalization of the TECDOC, e.g. irradiation assisted stress corrosion cracking (IASCC) of baffle-former bolts, which threatened the integrity of the vessel internals. In addition, concern of fretting wear of control rod guide tubes has been raised in Japan. These events led to new ageing management actions by both NPP operators and regulators. Therefore it was recognized that IAEA-TECDOC-1119 should be updated by incorporating those new events and their countermeasures. The objective of this report is to update relevant sections of the existing IAEA-TECDOC- 1119 in order to provide current ageing management guidance for PWR RVIs to all involved in the operation and regulation of PWRs and thus to help ensure PWR safety in IAEA Member States throughout their entire service life

  1. ISP-20 international standard problem-20: steam generator tube rupture: nuclear power plant Doel 2: Belgium

    The 1979 Doel 2 steam generator tube rupture (SGTR) incident was selected in 1985 as the basis for the next ISP-20. It was considered that the available data and recordings obtained on-line during this incident, provide a valuable data base for an ISP especially in the view of the fact that real plant data are scarcely available and provide an unique opportunity to test the code models and constitutive equations on full scaled facilities, thereby eliminating the scaling uncertainties in extrapolating data from test facilities to real plants. The existing RELAP 5 input model was the basis for the ISP-20 (open problem). This report gives a brief description of the Doel 2 plant and plant systems which conditioned the transient, such as the high pressure safety injection system, the charging and letdown system and the auxiliary feedwater system. It gives an analysis of the plant transient on the basis of the recorded data and computer diagnostics. It then specifies the general information available to all participants and presents a brief description of the various thermalhydraulic system codes used by the participants. The numerical results from the different participants are then discussed for each phase of the transient, and the code run time statistics are given. The last section formulates some conclusions from this exercise and presents a number of recommendations for the selection of future ISPs based on real plant transients

  2. Analysis of body composition of the abdomen at the level of the 4th lumbar vertebral body by CT

    Body composition of the area at the level of the 4th lumbar vertebral section was studied on X-ray CT images in 62 normal volunteers (32 men and 30 women ), whose ages ranged from 20 and 79 years. The total cross-sectional area was smallest in persons in their twenties, irrespecstive of sex, and began to increase after the age of 30. The abdominal cavity and muscles had the highest cross-sectional ratio (34%) to the total body, followed by subcutaneous fat in men. In women, the subcutaneous fat and abdominal cavity had a ratio of 34% to the total body. According to age groups, men in their twenties and thirties had the highest ratio of the muscle to the total body, followed by that of abdominal cavity and subcutaneous fat. In the group older than 40, the ratio of organs to the total body was as follows: the abdominal cavity>muscle>subcutaneous fat. Since the age of 70, each ratio of the muscle or subcutaneous fat to the total body was the same. Women between their twenties and fifties had the highest ratio of subcutaneous fat to the total body. Since the age of 60, the ratio of the abdominal cavity became highest. The subcutaneous fat and abdominal cavity tended to increase with aging; and the muscles tended to decrease. The real area of the vertebra increased slightly, but the vertebral foramen tended to decrease with aging. In men, mean areas of the muscles were as follows: abdominis lateralis>erector spinae>psoas major>quadratus lumborum and transversospinalis>rectus abdominis muscle. The same tendency was observed for women, except for the quadratus lumborum and rectus abdominis muscle. According to Rohrer index, the real areas of all components except the vertebral foramen tended to increase in the order of types A, C, and D in men. In women, the real area of the subcutaneous fat increased as well in the order of types A, C, and D. (Namekawa, K)

    This paper presents recent operating results of Coal Tech`s second generation, air cooled, slagging coal combustor, and its application to power plants in the 1 to 20 MW range. This 20 MMBtu/hour combustor was installed in a new demonstration plant in Philadelphia, PA in 1995. It contains the combustion components of a 1 MWe coal fired power plant, a 17,500 lb/hour steam boiler, coal storage and feed components, and stack gas cleanup components. The plant`s design incorporates improvements resulting from 2,000 hours of testing between 1987 and 1993 on a first generation, commercial scale, air cooled combustor of equal thermal rating. Since operations began in early 1996, a total of 51 days of testing have been successfully completed. Major results include durability of the combustor`s refractory wall, excellent combustion with high ash concentration in the fuel, removal of 95% to 100% of the slag in the combustor, very little ash deposition in the boiler, major reduction of in-plant parasitic power, and simplified power system control through the use of modular designs of sub-systems and computer control. Rapid fuel switching between oil, gas, and coal and turndown of up to a factor of three was accomplished. All these features have been incorporated in advanced coal fired plant designs in the 1 to 20 MWe range. Incremental capital costs are only $100 to $200/kW higher than comparable rated gas or oil fired steam generating systems. Most of its components and subsystems can be factory assembled for very rapid field installation. The low capital, low operating costs, fuel flexibility, and compatibility with very high ash fuels, make this power system very attractive in regions of the world having domestic supplies of these fuels.

    Nuclear power plant of VVER-440/213 designed by the former USSR have a number of special features. As a consequence of these features the transient behaviour of such a reactor system should be different from the PWR system behaviour. To study the transient behaviour of the Hungarian Paks Nuclear Power Plant of VVER-440/213-type both analytical and experimental activities have been performed. The experimental basis of the research in the PMK-2 integral-type test facility , which is a scaled down model of the plant. Experiments performed on this facility have been used to assess thermal-hydraulic system codes. Four tests were selected for {open_quotes}Standard Problem Exercises{close_quotes} of the International Atomic Energy Agency. Results of the 4th Exercise, of high international interest, are presented in the paper, focusing on the essential findings of the assessment of computer codes.

  5. Modeling climate change impacts on maize growth with the focus on plant internal water transport

    Heinlein, Florian; Biernath, Christian; Klein, Christian; Thieme, Christoph; Priesack, Eckart

    2015-04-01

    Based on climate change experiments in chambers and on field measurements, the scientific community expects regional and global changes of crop biomass production and yields. In central Europe one major aspect of climate change is the shift of precipitation towards winter months and the increase of extreme events, e.g. heat stress and heavy precipitation, during the main growing season in summer. To understand water uptake, water use, and transpiration rates by plants numerous crop models were developed. We tested the ability of two existing canopy models (CERES-Maize and SPASS) embedded in the model environment Expert-N5.0 to simulate the water balance, water use efficiency and crop growth. Additionally, sap flow was measured using heat-ratio measurement devices at the stem base of individual plants. The models were tested against data on soil water contents, as well as on evaporation and transpiration rates of Maize plants, which were grown on lysimeters at Helmholtz Zentrum München and in the field at the research station Scheyern, Germany, in summer 2013 and 2014. We present the simulation results and discuss observed shortcomings of the models. CERES-Maize and SPASS could simulate the measured dynamics of xylem sap flow. However, these models oversimplify plant water transport, and thus, cannot explain the underlying mechanisms. Therefore, to overcome these shortcomings, we additionally propose a new model, which is based on two coupled 1-D Richards equations, describing explicitly the plant and soil water transport. This model, which has previously successfully been applied to simulate water flux of 94 individual beech trees of an old-grown forest, will lead to a more mechanistic representation of the soil-plant-water-flow-continuum. This xylem water flux model was now implemented into the crop model SPASS and adjusted to simulate water flux of single maize plants. The modified version is presented and explained. Basic model input requirements are the plant

    2015-01-01

    Full Text Available In the preparation for missions to Mars, basic knowledge of the mechanisms of growth and development of living plants under microgravity (micro-g conditions is essential. Focus has centered on the g-effects on rigidity, including mechanisms of signal perception, transduction, and response in gravity resistance. These components of gravity resistance are linked to the evolution and acquisition of responses to various mechanical stresses. An overview is given both on the basic effect of hypergravity as well as of micro-g conditions in the cell wall changes. The review includes plant experiments in the US Space Shuttle and the effect of short space stays (8–14 days on single cells (plant protoplasts. Regeneration of protoplasts is dependent on cortical microtubules to orient the nascent cellulose microfibrils in the cell wall. The space protoplast experiments demonstrated that the regeneration capacity of protoplasts was retarded. Two critical factors are the basis for longer space experiments: a. the effects of gravity on the molecular mechanisms for cell wall development, b. the availability of facilities and hardware for performing cell wall experiments in space and return of RNA/DNA back to the Earth. Linked to these aspects is a description of existing hardware functioning on the International Space Station.

  7. Calculation of DPA in the Reactor Internal Structural Materials of Nuclear Power Plant

    Kim, Yong Deong; Lee, Hwan Soo [KHNP-CRI, Daejeon (Korea, Republic of)

    2014-10-15

    The embrittlement is mainly caused by atomic displacement damage due to irradiations with neutrons, especially fast neutrons. The integrity of the reactor internal structural materials has to be ensured over the reactor life time, threatened by the irradiation induced displacement damage. Accurate modeling and prediction of the displacement damage is a first step to evaluate the integrity of the reactor internal structural materials. Traditional approaches for analyzing the displacement damage of the materials have relied on tradition model, developed initially for simple metals, Kinchin and Pease (K-P), and the standard formulation of it by Norgett et al. , often referred to as the 'NRT' model. An alternative and complementary strategy for calculating the displacement damage is to use MCNP code. MCNP uses detailed physics and continuous-energy cross-section data in its simulations. In this paper, we have performed the evaluation of the displacement damage of the reactor internal structural materials in Kori NPP unit 1 using detailed Monte Carlo modeling and compared with predictions results of displacement damage using the classical NRT model. The evaluation of the displacement damage of the reactor internal structural materials in Kori NPP unit 1 using detailed Monte Carlo modeling has been performed. The maximum value of the DPA rate was occurred at the baffle side of the reactor internal where the node has the maximum neutron flux.

  8. The Daya Bay nuclear power plant performance. An example of international cooperation

    Technology transfer is an integral part of Framatome's general approach to its Chinese partners for the Daya Bay, Ling Ao, and Qinshan phase 2 nuclear power plant projects. It has been the subject of major operations covering all activities relevant to project management, design and engineering, manufacturing, and maintenance know-how. This presentation is more particularly devoted to nuclear island maintenance knowledge, which has been extensively transferred by Framatome to the Daya Bay plant owner over a period of four years, through a program including the constitution of mixed Franco-Chinese teams to handle plant maintenance, shadow training of Chinese specialists in the maintenance work performed by Framatome or its subcontractors in France, and theoretical training sessions on equipment mockups in China and France.

    Full Text Available Unstable economic conditions in Ukraine adversely affect the financial and business enterprises. Further escalation of the crisis threatens reduction of investments in Ukraine,outflow of foreign currency loans rise, complexity refinance foreign debt and so on. Financial conditions have deteriorated and risks of slower economic growth increased. This situation causes the failure of planned management tasks for companies developing their business. Therefore, to ensure the success oftheir operation, they should give more attention to the risk that affect their activities. According to international experience can confidently say that it is possible to recommend the regulatory authorities and companies adopt the practice in internal control on how COSO, the implementation of which is mandatory for all companies that are listed on international stock exchanges. Implementation of the components of internal control by the method COSO (the example of JSC "Lebedinsky Seed Plant" will contribute to the optimization of process control and allow owners to focus on achieving business objectives without being distracted by the current inspection activities.

  20. 2. International Symposium on Nuclear Power Plant Life Management [Opening remarks

    Mr. Yury A. Sokolov IAEA, Mr. Yang Dazhu CAEA, Ladies and Gentlemen, Good morning. First of all, I'm greatly honored, on behalf of China National Nuclear Corporation (CNNC) - the sponsor of this symposium, to extend my warm welcome to all delegates present here in Shanghai, and warm congratulation for the convening of this symposium as scheduled. Since the end of 20th century, the international oil price has kept going up, and the concern over environmental protection has increasingly outstood. So many countries in the world have adjusted their energy development strategies in recent years. As a result, nuclear energy, as a clean, safe and reliable energy source, is attracting more and more attentions. The Chinese government has also adjusted its nuclear development strategy from 'moderate development' to 'active development', aiming at optimizing the energy mix, mitigating environment pollution pressure and meeting the fast growing energy needs. In the State Medium- and Long-term Nuclear Power Development Program (2005-2020) approved in principle by the Chinese government in 2006, it is clearly set out that the installed capacity of nuclear power will reach 40 GWe, and another 18 GWe under construction by 2020. The share of nuclear power will rise from the present 2% up to 4%. At the end of 2006, China commenced the construction of Unit 3 and 4 of Qinshan II, and Unit 3 and 4 of Ling Ao by taking full advantages of advanced and mature technologies. To date, the Chinese government has determined the line of the third generation nuclear power technologies. Several new projects will be started in succession at the sites of Sanmen in Zhejiang Province and Haiyang in Shangdong Province, which marks that China' nuclear power has evolved into an era of large-scale development. I. Status of Nuclear Power Plants of CNNC CNNC takes control of all the 11 operating nuclear power units in China by absolute or relative proprietary, among which 4 units with an installed capacity

  2. International legal and political issues associated with the export/import of nuclear power plants

    The benefits of nuclear power can be achieved by most nations only through international commerce that has been shaped by political considerations and implemented through legal instruments. The end product is a structure of legal agreements designed to implement the basic political and commercial decisions that are required for any nation to enter the nuclear power arena. The IAEA Statute, the Non-Proliferation Treaty and regional nuclear agreements have reflected the international political consensus concerning nuclear power. In recent years, however, events have occurred that in all probability will result in additional international arrangements. It is expected that the increase in terrorist activities will result in greater physical protection commitments, that concern for weapons proliferation will result in further definition of sanctions, and that such troublesome issues as double labelling of materials will be discussed by the international community. In areas such as bilateral agreements between nations, commercial arrangements and export licences, this is a period of rethinking, renegotiating, and readjusting. The result is a degree of uncertainty and lack of stability that could so jeopardize the potential for nuclear transfers that the nuclear energy option may not vest. While there always will be questions and issues, it is essential to settle some of the key problems without delay so that nuclear benefits can be realized. (author)

  5. Nuclear power plants - Instrumentation and control systems important for safety - Classification (International Electrotechnical Commission Standard Publication 1226:1993)

    This international standard established a method of classification of the information and command functions for nuclear power plants, and the I and C and equipment that provide those functions, into categories that designate the importance for safety of the functions, and the associated systems and equipment. The resulting classification then determines relevant design criteria. The design criteria are the measures of quality by which the adequacy of each functions, and the associated systems and equipment in relation to its importance to plant safety is ensured. In this standard, the criteria are those of functionality, reliability, performance, environmental durability and quality assurance. This standard is applicable to all the information and command functions, and the instrumentation and control systems and equipment that provide those functions. The functions, systems and equipment under consideration provide automated protection, closed or open loop control, and information to the operating staff. They keep the NPP conditions inside the safe operating envelope and provide automatic actions, or enable manual actions, that mitigate accidents or prevent or minimize radioactive releases to the site or wider environment. The functions, and the associated systems and equipment that fulfill these roles safeguard the health and safety of the NPP operators and the public. This standard complements, and does not replace or supersede, the Safety Guides and Codes of Practice published by the International Atomic Energy Agency

  12. Licensing of nuclear power plants: The case of Sweden in an international comparison

    Efficient power plant licensing procedures are essential for the functioning of deregulated electricity markets. The purpose of this paper is to review and analyse the licensing process for nuclear power plants in Sweden, and in part contrast the Swedish case with the corresponding approaches in a selection of other countries. This approach permits a discussion of how licensing processes can be altered and what the benefits and drawbacks of such changes are. The paper highlights and discusses a number of important legal issues and implications, including, for instance: (a) the role of political versus impartial decision-making bodies; (b) the tension between national policy goals and implementation at the local level; (c) public participation and access to justice; (d) consistency and clarity of the legal system; and (e) the introduction of license time limits.

  13. International symposium on nuclear power plant life management. Book of extended synopses

    A number of nuclear power plants in operation are meeting the problems of aging. Besides maintaining safety and reliability many NPP owners are concerned with service life extension, life management policy, and reactor maintenance procedures. The topics covered in this report are devoted to: NPP life management, economics and technical aspects of service life extension, reactor licensing procedures; aging of reactor components; physical radiation effects on reactor materials; corrosion; mechanical properties of reactor materials; reactor control systems; reactor safety systems

  14. Management of operational safety in nuclear power plants. INSAG-13. A report by the International Nuclear Safety Advisory Group

    The International Atomic Energy Agency's activities relating to nuclear safety are based upon a number of premises. First and foremost, each Member State bears full responsibility for the safety of its nuclear facilities. States can be advised, but they cannot be relieved of this responsibility. Secondly, much can be gained by exchanging experience; lessons learned can prevent accidents. Finally, the image of nuclear safety is international; a serious accident anywhere affects the public's view of nuclear power everywhere. With the intention of strengthening its contribution to ensuring the safety of nuclear power plants, the IAEA established the International Nuclear Safety Advisory Group (INSAG), whose duties include serving as a forum for the exchange of information on nuclear safety issues of international significance and formulating, where possible, commonly shared safety principles. Engineering issues have received close attention from the nuclear community over many years. However, it is only in the last decade or so that organizational and cultural issues have been identified as vital to achieving safe operation. INSAG's publication No. 4 has been widely recognized as a milestone in advancing thinking about safety culture in the nuclear community and more widely. The present report deals with the framework for safety management that is necessary in organizations in order to promote safety culture. It deals with the general principles underlying the management of operational safety in a systematic way and provides guidance on good practices. It also draws on the results of audits and reviews to highlight how shortfalls in safety management have led to incidents at nuclear power plants. In addition, several specific issues are raised which are particularly topical in view of organizational changes that are taking place in the nuclear industry in various countries. Advice is given on how safety can be managed during organizational change, how safety

  15. International comparison of economic and technical indexes of nuclear power plant construction

    The comparison of capital costs of the construction of nuclear power plants takes into consideration the following aspects: the delineation of the installation, the determination of costs and their break-down, the impact of the time factor, the conversion of the costs to a comparable unit. Power plants are always compared with roughly the same power capacity, this even when conditions for construction are not fully comparable. Construction costs may be divided into, e.g., pre-construction costs, direct capital costs, indirect capital costs, interest during construction. The time factor is manifest in the duration of construction and in the concrete year of construction for which the comparison is being made. The inflationary rise in prices and interests are increasing capital costs by roughly 5 - 8% per annum. The comparison of costs expressed in different currencies is made either by conversion using the rate of exchange or by comparing the time expended for the construction of the power plant. Various methods of comparison are discussed. (J.B.). 7 refs

  16. Internal Technical Report, Safety Analysis Report 5 MW(e) Raft River Pilot Plant

    Brown, E.S.; Homer, G.B.; Spencer, S.G.; Shaber, C.R.

    1980-05-30

    The Raft River Geothermal Site is located in Southern Idaho's Raft River Valley, southwest of Malta, Idaho, in Cassia County. EG and G idaho, Inc., is the DOE's prime contractor for development of the Raft River geothermal field. Contract work has been progressing for several years towards creating a fully integrated utilization of geothermal water. Developmental progress has resulted in the drilling of seven major DOE wells. Four are producing geothermal water from reservoir temperatures measured to approximately 149 C (approximately 300 F). Closed-in well head pressures range from 69 to 102 kPa (100 to 175 psi). Two wells are scheduled for geothermal cold 60 C (140 F) water reinjection. The prime development effort is for a power plant designed to generate electricity using the heat from the geothermal hot water. The plant is designated as the ''5 MW(e) Raft River Research and Development Plant'' project. General site management assigned to EG and G has resulted in planning and development of many parts of the 5 MW program. Support and development activities have included: (1) engineering design, procurement, and construction support; (2) fluid supply and injection facilities, their study, and control; (3) development and installation of transfer piping systems for geothermal water collection and disposal by injection; and (4) heat exchanger fouling tests.

  17. Alarm Photosynthesis: Calcium Oxalate Crystals as an Internal CO2 Source in Plants.

    Calcium oxalate crystals are widespread among animals and plants. In land plants, crystals often reach high amounts, up to 80% of dry biomass. They are formed within specific cells, and their accumulation constitutes a normal activity rather than a pathological symptom, as occurs in animals. Despite their ubiquity, our knowledge on the formation and the possible role(s) of these crystals remains limited. We show that the mesophyll crystals of pigweed (Amaranthus hybridus) exhibit diurnal volume changes with a gradual decrease during daytime and a total recovery during the night. Moreover, stable carbon isotope composition indicated that crystals are of nonatmospheric origin. Stomatal closure (under drought conditions or exogenous application of abscisic acid) was accompanied by crystal decomposition and by increased activity of oxalate oxidase that converts oxalate into CO2 Similar results were also observed under drought stress in Dianthus chinensis, Pelargonium peltatum, and Portulacaria afra Moreover, in A. hybridus, despite closed stomata, the leaf metabolic profiles combined with chlorophyll fluorescence measurements indicated active photosynthetic metabolism. In combination, calcium oxalate crystals in leaves can act as a biochemical reservoir that collects nonatmospheric carbon, mainly during the night. During the day, crystal degradation provides subsidiary carbon for photosynthetic assimilation, especially under drought conditions. This new photosynthetic path, with the suggested name "alarm photosynthesis," seems to provide a number of adaptive advantages, such as water economy, limitation of carbon losses to the atmosphere, and a lower risk of photoinhibition, roles that justify its vast presence in plants.

  18. A 4th-Order Particle-in-Cell Method with Phase-Space Remapping for the Vlasov-Poisson Equation

    Myers, Andrew; Van Straalen, Brian

    2016-01-01

    Numerical solutions to the Vlasov-Poisson system of equations have important applications to both plasma physics and cosmology. In this paper, we present a new Particle-in-Cell (PIC) method for solving this system that is 4th-order accurate in both space and time. Our method is a high-order extension of one presented previously [B. Wang, G. Miller, and P. Colella, SIAM J. Sci. Comput., 33 (2011), pp. 3509--3537]. It treats all of the stages of the standard PIC update - charge deposition, force interpolation, the field solve, and the particle push - with 4th-order accuracy, and includes a 6th-order accurate phase-space remapping step for controlling particle noise. We demonstrate the convergence of our method on a series of one- and two- dimensional electrostatic plasma test problems, comparing its accuracy to that of a 2nd-order method. As expected, the 4th-order method can achieve comparable accuracy to the 2nd-order method with many fewer resolution elements.

  1. Internal radiation exposure dose in Iwaki city, Fukushima prefecture after the accident at Fukushima Dai-ichi Nuclear Power Plant.

    Makiko Orita

    Full Text Available As a result of the accident at the Fukushima Daiichi Nuclear Power Plant (FNPP on 11 March 2011, a huge amount of radionuclides, including radiocesium, was released and spread over a wide area of eastern Japan. Although three years have passed since the accident, residents around the FNPP are anxious about internal radiation exposure due to radiocesium. In this study, we screened internal radiation exposure doses in Iwaki city of Fukushima prefecture, using a whole-body counter. The first screening was conducted from October 2012 to February 2013, and the second screening was conducted from May to November 2013. Study participants were employees of ALPINE and their families who underwent examination. A total of 2,839 participants (1,366 men and 1,473 women, 1-86 years old underwent the first screening, and 2,092 (1,022 men and 1,070 women, 1-86 years old underwent the second screening. The results showed that 99% of subjects registered below 300 Bq per body in the first screening, and all subjects registered below 300 Bq per body in the second screening. The committed effective dose ranged from 0.01-0.06 mSv in the first screening and 0.01-0.02 mSv in the second screening. Long-term follow-up studies are needed to avoid unnecessary chronic internal exposure and to reduce anxiety among the residents by communicating radiation health risks.

  2. Internal active power reserve management in Large scale PV Power Plants

    Craciun, Bogdan-Ionut; Spataru, Sergiu; Kerekes, Tamas;

    Active Power Reserves (APRs) provided through curtailment (iAPRs) or through auxiliary storage systems (aAPR) with Large scale PV Power Plants (LPVPPs) becomes a reality in the near future with high penetration levels of Photovoltaic (PV) power into the grid. Therefore, this paper analyses the...... solutions for iAPR fulfilment in central inverter based - LPVPPs in terms of their layout, configuration and control architecture. During iAPR supply, the LPVPP has to operate under its Maximum Power Point (MPP), which means that the MPP algorithm has to undergo several changes. For this purpose, the paper...

  3. AN INTERNATIONAL VIEW OF DIFFERENT APPROACHESFOR FAULTS DETECTION AND IDENTIFICATIONIN NUCLEAR POWER PLANTS

    2000-01-01

    An extensive survey of computer-based systems that apply different approaches for faults diagnostics and identifications in nuclear power plants (NPPs) was presented. In the light of reviewed material, the classification criteria were developed. The classification of computational techniques (class of computing devices, class of programming languages, and simulation programs) was discussed. The classification of theoretical aspects applied (brief aspects, and detailed aspects) in computer-based diagnostic systems were established. The classification of metholology applied (symbolic reasoning methodology, event-based methodology, and function-based methodology) in the diagnostic systems was also depicted. In the end, the personal comments on the reviewed material, and scope of the study were described.

  4. Estimation of internal exposure dose due to Fukushima Daiichi nuclear power plant accidents

    Detailed analysis of internal exposure dose in 173 people sent for dealing with the Accident and stayed nearby during the period Mar 11-Apr 10, 2011, was reported. They were 156 men and 17 women, 42.2 years old in average and stayed for average 4.8 days. Analysis was done for following 4 groups of people: in group 1, 45 people had stayed during the period of Mar 11-18 for average 4.3 days; group 2, 66 people during Mar 14-22 for 2.0 days; group 3, 31 people during Mar 28-31 for 5.8 days; and group 4, 31 people during Mar 22-Apr 10 for 10.6 days. Internal radioactivity was measured for 20 min in the whole body counter placed in a low-background, iron-surrounded room in Nagasaki University. The detector was a pair of NaI (Tl) scintillator of 8 in. (diameter) x 4 in. (thickness) equipped at upper and lower portions. Nuclides measured were I-131 (at 0.364 MeV and others), Cs-134 (0.605, 0.796 MeV), Cs-137 (0.662 MeV), of which lowest detection limits were 68 Bq for I, and 28 Bq for Cs. Overall average detection rates of the respective nuclide above were found to be 31.8% (55/173 people), 37.6% (65) and 32.4% (56). In group 1, >800 Bq of the nuclides were found in the body, but in later groups, radioactivity was lower. Detection rate and internal radioactivity were thus found to be highest in those stayed immediately after the Accident. (T.T.)

  5. Guest Editor's introduction: Selected papers from the 4th USENIX Conference on Object-Oriented Technologies and Systems

    Sventek, Joe

    1998-12-01

    Hewlett-Packard Laboratories, 1501 Page Mill Road, Palo Alto, CA 94304, USA Introduction The USENIX Conference on Object-Oriented Technologies and Systems (COOTS) is held annually in the late spring. The conference evolved from a set of C++ workshops that were held under the auspices of USENIX, the first of which met in 1989. Given the growing diverse interest in object-oriented technologies, the C++ focus of the workshop eventually became too narrow, with the result that the scope was widened in 1995 to include object-oriented technologies and systems. COOTS is intended to showcase advanced R&D efforts in object-oriented technologies and software systems. The conference emphasizes experimental research and experience gained by using object-oriented techniques and languages to build complex software systems that meet real-world needs. COOTS solicits papers in the following general areas: application of, and experiences with, object-oriented technologies in particular domains (e.g. financial, medical, telecommunication); the architecture and implementation of distributed object systems (e.g. CORBA, DCOM, RMI); object-oriented programming and specification languages; object-oriented design and analysis. The 4th meeting of COOTS was held 27 - 30 April 1998 at the El Dorado Hotel, Santa Fe, New Mexico, USA. Several tutorials were given. The technical program proper consisted of a single track of six sessions, with three paper presentations per session. A keynote address and a provocative panel session rounded out the technical program. The program committee reviewed 56 papers, selecting the best 18 for presentation in the technical sessions. While we solicit papers across the spectrum of applications of object-oriented technologies, this year there was a predominance of distributed, object-oriented papers. The accepted papers reflected this asymmetry, with 15 papers on distributed objects and 3 papers on object-oriented languages. The papers in this special issue are

    NONE

    2001-07-01

    The aim of the European commission which has fixed to 12% the share of renewable energies in the total energy consumption up to 2010, is to develop the biomass sector. Co-firing is a solution that allows to increase significantly the use of biomass because it does not require important investments. Today, about 150 power plants in Europe use co-firing. An Altener project named 'Cofiring' has ben settled in order to bring together and analyze the European experience in this domain and to sustain and rationalize the design of future projects. The conclusions of this study, coordinated by VTT Energy and which involves CARMEN (Germany), CBE (Portugal), the Danish centre for landscape and planning, ITEBE (France), KOBA (Italy), SLU (Sweden), and EVA (Austria), were presented during this international seminar.

  7. Application of the Dangerous Preparation Directive: consequences on plant protection products in the internal market

    Maristella Rubbiani

    2010-03-01

    Full Text Available Legislative Decree March 2003, n. 65 brought about implementation of Directive 1999/45/ EC of the European Parliament and of the Council dated 31 May 1999 and Directive 2001/60/EC of the Commission dated 7 August 2001 concerning laws, regulations and administrative provisions of the Member States relating to the classification, packaging and labelling of dangerous preparations come into force. Directive 1999/45/EC brought about a series of modifications representing the new regulatory framework for dangerous preparations. The above-mentioned Decree supplies the criteria for the evaluation of hazardous preparations, regardless of their intended use, and completes previously undertaken steps, in strict connection with the analogous Directives of the EU, for the problematic complexity of the classification, packaging and labelling of dangerous substances and preparations. The applicative importance of Directive 99/45/EC derives directly from these innovations. Among these, for the first time, the category of "dangerous for the environment" has been extended also to preparations. Moreover, also for the first time, the scope of the Directive is extended to plant protection products and biocides. This paper provides an overview on the results of the hazard classification procedure carried out at national level for plant protection products in light of the new rules and the outcomes in terms of variations of the labels through comparison between previous and new classification. Furthermore the most significant issue which come up during the classification process and the criteria applied for their solution are also reported.

  8. Report on the 4th International Conference on monitoring, simulation, prevention and remediation of dense and debris flows - Debris Flow 2012

    Daniele de Wrachien

    2012-09-01

    Full Text Available Debris and hyper-concentrated flows are amongst the most destructive of all water-related disasters. These hazards are likely to become more frequent and more important in the future due to the effects of the increase in population, urbanization, land subsidence and the impact of climate change. They affect both rural and urban environments, particularly in river basins and in mountain areas. In recent years, they have attracted more and more attention from the scientific and professional communities due to the number of lives lost, and there is growing public concern for the future. New methods and measures are required to cope with debris flow changes and to achieve a harmonious balance between the environment and economic forces.

  12. Working material. IAEA seismic safety of nuclear power plants. International workshop on lessons learned from strong earthquake

    The International Workshop on Lessons Learned from Strong Earthquake was held at Kashiwazaki civic plaza, Kashiwazaki, Niigata-prefecture, Japan, for three days in June 2008. Kashiwazaki-Kariwa NPP (KK-NPP) is located in the city of Kashiwazaki and the village of Kariwa, and owned and operated by Tokyo Electric Power Company Ltd. (TEPCO). After it experienced the Niigata-ken Chuetsu-oki earthquake in July 2007, IAEA dispatched experts' missions twice and held technical discussions with TEPCO. Through such activities, the IAEA secretariat and experts obtained up-dated information of plant integrity, geological and seismological evaluation and developments of the consultation in the regulatory framework of Japan. Some of the information has been shared with the member states through the reports on findings and lessons learned from the missions to Japan. The international workshop was held to discuss and share the information of lessons learned from strong earthquakes in member states' nuclear installations. It provided the opportunity for participants from abroad to share the information of the recent earthquake and experience in Japan and to visit KK-NPP. And for experts in Japan, the workshop provided the opportunity to share the international approach on seismic-safety-related measures and experiences. The workshop was organised by the IAEA as a part of an extra budgetary project, in cooperation with OECD/NEA, hosted by Japanese organisations including Nuclear and Industrial Safety Agency (NISA), Nuclear Safety Commission (NSC), and Japan Nuclear Energy Safety Organization (JNES). The number of the workshop participants was 70 experts from outside Japan, 27 countries and 2 international organisations, 154 Japanese experts and 81 audience and media personnel, totalling to 305 participants. The three-day workshop was open to the media including the site visit, and covered by NHK (the nation's public broadcasting corporation) and nation-wide and local television

  14. Individual monitoring of internal exposure to uranium oxides in two fuel fabrication plants

    Individual monitoring of personal exposure to inhalation of uranium oxides throughout the manufacture of fuel for pressurized water reactor (PWR) includes lung gamma-spectrometry, fecal analysis and urine analysis. Examination of the results shows the following: internal exposure is the consequence of repeated intake incidents as revealed by early peaks of urinary and particularly fecal elimination; a shift is often observed with the results of aerosol concentration measured through air collectors; the measured variations of uranium lung incorporations are relatively fast (apparent mean period 165 d). Correct evaluation of the effective dose equivalent from inhalation requires further information concerning the aerosol size distribution at work stations, the physico-chemical characteristics of the product leading to an estimate of its actual biological solubility, and the measurement of the fraction of aerosol liable to intake with an individual portable collector

The various types of missile sources which should be considered are discussed, and an attempt is made to summarize key considerations where practice is sufficiently consistent. Secondary effects and an example of a simple procedure for making a comprehensive assessment of the protection against such effects are discussed as soon as a number of techniques which can be used to provide missile protection

  17. Report of the COG/IAEA international workshop on managing nuclear safety at CANDU (PHWR) plants. Working material

    The workshop, hosted by COG and co-sponsored by the International Atomic Energy Agency (IAEA, Vienna) was held in Toronto, April 28 - May 1st, 1997. The 40 participants included senior managers from IAEA member countries operating or constructing CANDU (PHWR) stations. All the offshore utilities with PHWR stations in Korea, Romania, India, Argentina, Pakistan, and China were present with their domestic counterparts from Ontario Hydro Nuclear, Hydro Quebec, New Brunswick Power, and AECL. The objectives of the workshop were to: provide a forum for exchange of ideas among nuclear safety managers operating CANDU (PHWR) stations and to learn from each other's experiences; to foster sharing of information on different operating approaches to managing safety and, in particular, to highlight the strategies for controlling the overall plant risk to a low level; to identify and discuss issues of mutual interest pertinent to PHWR stations and to define future follow-up activities.

  19. Measures to assess and to assure the integrity of RPV-internals at Isar, Unit 1 Nuclear Power Plant

    As visual examinations carried out in autumn 1994 detected cracks in a German BWR plant due to intergranular stress corrosion cracking in several core shroud components manufactured from 1.4550 steel, precautionary examinations and assessments were performed for all other plants. In accordance with these analyses, it can be stated for Isar, Unit 1 that the heat treatment to which the components in question were subjected in the course of manufacture cannot have caused sensitization of the material, and that crack formation due to the damage mechanism primarily identified in the reactor pressure vessel internals at Wuergassen Nuclear Power Station need not be feared. Although the material and corrosion-chemical assessments performed to date did not give any indications for the other crack formation mechanisms that are theoretically relevant for reactor pressure vessel internals (IGSCC due to weld sensitization, IASCC), visual examinations with a limited scope will be carried out with the independent expert's agreement during the scheduled inservice inspections. The fluid-dynamic and structure-mechanical analyses showed that the individual components are subjected only to low loadings, even in the event of accidents, and that the safety objectives shutdown and residual heat removal can be fulfilled even in the case of large postulated cracks. The fracture-mechanics analyses indicated critical through-wall crack lengths which, however, can be promptly and reliably detected during random inservice inspections even when assuming stress corrosion cracking and irradiation-induced low-toughness material conditions. In addition, both the VGB and the Isar, Unit 1 licensee are pursuing further prophylactic measures such as alternative water chemistry modes and an appropriate repair and replacement concept.

  20. Effects of mean stress on the fatigue strength under oscillation stresses with ductile steels. 4th technical report

    The effect of the mean stress is quantified and an assessment is made showing how it is applied in technical codes. With respect to the application to nuclear power plants, the regulations for reactor pressure vessels are reviewed. It is to be checked whether the design was made for nominal stress peaks or for elongation amplitudes at the point of highest load. Considering different failure criteria, note that the effects of a given mean stress are different with respect to yield strength and tensile strength. This is to be considered in the method of approximation for the fatigue strength. (DG)
