  4. 30th Report by the Swiss commission to monitor radioactivity for the years 1987-1988 for the attention of the Bundesrat

    Radon daughter-products are the largest contributor to the radiation exposure experienced by the population in Switzerland. It is roughly twice as large as the total of the natural doses as a result of radioactivity in the body, in the ground and in building materials as well as the radiation from the cosmos. The radioactivity from Chernobyl was still being monitored intensively in the years covered by the reports; at the end of 1988 artificial radioactivity was no longer evident in foodstuffs. The power stations in Switzerland have complied with the emission limits during the years covered by the reports

    Annual JRT-15 Target: Conduct experiments and analysis to quantify the impact of broadened current and pressure profiles on tokamak plasma confinement and stability. Broadened pressure profiles generally improve global stability but can also affect transport and confinement, while broadened current profiles can have both beneficial and adverse impacts on confinement and stability. This research will examine a variety of heating and current drive techniques in order to validate theoretical models of both the actuator performance and the transport and global stability response to varied heating and current drive deposition.

  6. Welcome address to 30th international meeting on Reduced Enrichment for Research and Test Reactors, 6 October 2008, Washington, D.C., USA

    The RERTR meetings, of course, have a special role among our activities. They are important not only for what is presented in the formal technical sessions, but also for what takes place in the informal gatherings, side meetings, and personal encounters. The IAEA also has participated as an observer in the International Fuel Development Working Group, a highly important effort that is overseeing the multinational cooperative research and development effort for very high density LEU fuel. Remarkable achievements of GTRI are the conversion to LEU or final shutdown prior to conversion of 62 research reactors, the return to the United States of more than 1100 kg of spent HEU fuel and more than 1800 kg of spent LEU fuel and the return to Russia of more than 600 kg of spent and fresh HEU fuel. But while much has been achieved so far, vulnerabilities remain. HEU continues to be used for military purposes in a number of States; about 150 civilian and military research reactors are still using HEU and important quantities of fresh; and spent HEU fuel continues to be stored in different countries. All this calls for continued efforts, with a sense of urgency and more coherent global action. Some of the measures that might be taken are as follows: The countries involved should join forces to step up their efforts towards minimizing and eventually eliminating the civilian and in due course the military use of HEU. Financing and other incentives should be made available where needed to assist countries with conversion operations. All countries should agree to stop producing fissile material for use in nuclear weapons. The elements are already in place for such an agreement, in the form of the proposed Fissile Material Cut-off Treaty. It is high time to negotiate and conclude such a treaty. To build confidence, countries with civilian and military HEU stockpiles should declare the size of those stockpiles and publish a schedule under which the remaining HEU will be verifiably

  9. The 30th JAIF annual conference

    This is a preprint of the 30th JAIF (Japan Atomic Industrial Forum) Annual Conference held on April 9-11, 1997. In Japan today, the general public has a critical view of nuclear development, and there is no doubt that the sodium leakage at the fast-breeder reactor Monju in December 1995, and the accident at the bituminization facility for low-level radioactive waste at the Power Reactor and Nuclear Fuel Development Corporation's Tokai Facility on March 11 of this year are parts of the reason. Although the amount of radioactivity released from the bituminization facility was too small to have any effect either on people or the environment, all who are involved in nuclear power development must keep in mind that such an event itself should not have happened at all. Now that it has, it is necessary to thoroughly investigate the whys and hows, determine what should be corrected, and implement the changes as quickly as possible. Under such conditions, following three theme were selected in the conference: 1) Alternative energies. Roles and prospect, 2) Managing waste products from energy, and 3) Regional framework for nuclear developing Asia. (G.K.)

    2003-06-09

    This meeting is the sixteenth oilheat industry technology meeting held since 1984 and the third since the National Oilheat Research Alliance (NORA) was formed. This year's symposium is a very important part of the effort in technology transfer, which is supported by the Oilheat Research Fuel Flexibility Program under the United States Department of Energy, Distributed Energy and Electricity Reliability Program (DEER). The foremost reason for the conference is to provide a platform for the exchange of information and perspectives among international researchers, engineers, manufacturers, service technicians, and marketers of oil-fired space-conditioning equipment. The conference provides a conduit by which information and ideas can be exchanged to examine present technologies, as well as helping to develop the future course for oil heating advancement. These conferences also serve as a stage for unifying government representatives, researchers, fuel oil marketers, and other members of the oil-heat industry in addressing technology advancements in this important energy use sector. The specific objectives of the conference are to: (1) Identify and evaluate the current state-of-the-art and recommend new initiatives for higher efficiency, a cleaner environment, and to satisfy consumer needs cost effectively, reliably, and safely; (2) Foster cooperative interactions among federal and industrial representatives for the common goal of sustained economic growth and energy security via energy conservation.

    challenging research domains in condensed form. The diversity of the different topics is especially impressive. The 25th anniversary of Inverse Problems was celebrated with a service to the community, the publication of an issue of topical reviews selected by board members, which presented the achievements and state-of-the-art of the field. The 30th birthday of the journal is now approaching and we found it appropriate to include in the celebration the scientific community that supports the journal by their submissions. A conference, IPTA 2014: Inverse Problems - From Theory to Application (http://ipta2014.iopconfs.org/home), will be held in the home town of our publisher, IOP Publishing, in Bristol on 26-28 August 2014. The conference brings together top researchers, both from academia and industry, and will look at the scientific future of the field. Presentations by keynote speakers, which summarize what the board considers to be new trends, are complemented by contributions submitted by specialists and younger researchers in several minisymposia. To build a bridge to the future generation of researchers, a scientist at the beginning of their career will be giving a lecture. Let me finish with cordial thanks to all of our authors, referees, the members of the Editorial Board and International Advisory Panel, and the publishing team. I wish all of you a successful and healthy New Year and hope to meet many of you in August in Bristol.

    2012-01-01

    对第30届奥运会篮球比赛四强与中国女篮攻防技术统计数据分析发现,与世界强队相比,中国队在篮板球和抢断球以及封盖等方面有待提高;面对对手压迫性的防守,进攻时投篮命中率较差;没有充分发挥外围的进攻优势。这些都是导致中国女篮未能实现历史性突破的重要原因,同时也指出了中国女篮今后的努力方向。%In this paper, the statistical data of attack and defense technique of Chinese team and the four strong teams in women basketball match in the 30th Olympic game is analyzed. It is discovered that compared with world strong teams, Chinese women basketball team still has some disadvantages, such as: the rebound, ball hawk and enclosing cover should be improved; the shooting average in attack was low when the players faced oppressing defense; the attack advantages of exterior-line wasn't play fully. The above advantages were the important reasons of bad competition results achieved by Chinese women basketball team in the 30th Olympic game. At last, the striving direction of Chinese women basketball team in future is pointed out.

  20. Should local research ethics committees monitor research they have approved?

    Cave (née Pickworth), E.

    2000-01-01

    The function of local research ethics committees is to consider the ethics of research proposals using human participants. After approval has been given, there is no comprehensive system in place to monitor research and ensure that recommendations are carried out. Some suggest that research ethics committees are ideally placed to fulfil this function by carrying out random monitoring of research they have reviewed. The health service guideline creating local research ethics committees is unde...

  1. Clinical research monitoring: scenarios and challenges

    Gustavo Adolfo Sierra Romero

    2013-01-01

    Full Text Available Clinical research is essential for the development of new drugs, diagnostic tests and new devices. Clinical monitoring is implemented to improve the quality of research and attain high ethical and scientific standards. This review discusses the role of clinical monitors, taking into account the variety of scenarios in which medical research is developed, and highlights the challenges faced by research teams to ensure that patients rights are respected and that the social role of scientific research is preserved. Specific emphasis is given to the ethical dilemmas related to the multiple roles which clinical monitors play in the research framework, mainly those involving the delicate equilibrium between the loyalty to the sponsor and to the research subjects. The essential role of clinical monitoring for research developed in poor healthcare scenarios is highlighted as an approach to get the local infrastructure strengthening needed to achieve an adequate level of good clinical practices.

  4. Inscriptions on the Interior of the 30th Dynasty Coffin of Nefer-renepet from Akhmim

    Branislav Anđelković

    2016-02-01

    Full Text Available The anthropoid wooden coffin with plinth (L. 183.5 cm, datable to the mid–4th century B.C. (30th Dynasty, names Nefer-renepet, a dancer of Min from Akhmim. This object represents one of the artistically and technically superior coffins produced by Late Period Egyptian coffin workshops. It was formerly part of the Amherst collection, and was purchased by Ernest Brummer at a Sotheby, Wilkinson & Hodge auction in London in 1921, then donated the same year to the National Museum in Belgrade. The interior of the lid is distinguished by a remarkable ‘gliding Nut motif with upward streaming hair’ (an extremely important iconographic element while the interior of the trough is dominated by a line drawing of Imentet wearing a diagonallyveined maat-feather on her head. The interior decoration includes inscriptions written on the side facets. Written hastily in whitish-yellow line on a rough ground of thick black pigment (in contrast to the fine outer decoration of the coffin these barely legible Stundenwachen texts, are nonetheless significant, and are to be identified as abbreviated texts derived from the Book of Day and Book of Night. They are a manifestation of Late Period magical symbolism stemming from New Kingdom funerary compositions. Their presence on the coffin, however hurried, was intended to ease Nefer-renepet’s passage through the netherworld. Since 1992 the coffin of Nefer-renepet is kept in the Archaeological Collection of the Faculty of Philosophy, University of Belgrade.

  5. The IceCube Collaboration: contributions to the 30th International Cosmic Ray Conference (ICRC 2007)

    This paper bundles 40 contributions by the IceCube collaboration that were submitted to the 30th International Cosmic Ray Conference ICRC 2007. The articles cover studies on cosmic rays and atmospheric neutrinos, searches for non-localized, extraterrestrial νe, νμ and ντ signals, scans for steady and intermittent neutrino point sources, searches for dark matter candidates, magnetic monopoles and other exotic particles, improvements in analysis techniques, as well as future detector extensions. The IceCube observatory will be finalized in 2011 to form a cubic-kilometer ice-Cherenkov detector at the location of the geographic South Pole. At the present state of construction, IceCube consists of 52 paired IceTop surface tanks and 22 IceCube strings with a total of 1426 Digital Optical Modules deployed at depths up to 2350 m. The observatory also integrates the 19 string AMANDA subdetector, that was completed in 2000 and extends IceCube's reach to lower energies. Before the deployment of IceTop, cosmic air showers were registered with the 30 station SPASE-2 surface array. IceCube's low noise Digital Optical Modules are very reliable, show a uniform response and record waveforms of arriving photons that are resolvable with nanosecond precision over a large dynamic range. Data acquisition, reconstruction and simulation software are running in production mode and the analyses, profiting from the improved data quality and increased overall sensitivity, are well under way

  12. Nuclear Explosion Monitoring History and Research and Development

    Hawkins, W. L.; Zucca, J. J.

    2008-12-01

    Within a year after the nuclear detonations over Hiroshima and Nagasaki the Baruch Plan was presented to the newly formed United Nations Atomic Energy Commission (June 14, 1946) to establish nuclear disarmament and international control over all nuclear activities. These controls would allow only the peaceful use of atomic energy. The plan was rejected through a Security Council veto primarily because of the resistance to unlimited inspections. Since that time there have been many multilateral, and bilateral agreements, and unilateral declarations to limit or eliminate nuclear detonations. Almost all of theses agreements (i.e. treaties) call for some type of monitoring. We will review a timeline showing the history of nuclear testing and the more important treaties. We will also describe testing operations, containment, phenomenology, and observations. The Comprehensive Nuclear Test Ban Treaty (CTBT) which has been signed by 179 countries (ratified by 144) established the International Monitoring System global verification regime which employs seismic, infrasound, hydroacoustic and radionuclide monitoring techniques. The CTBT also includes on-site inspection to clarify whether a nuclear explosion has been carried out in violation of the Treaty. The US Department of Energy (DOE) through its National Nuclear Security Agency's Ground-Based Nuclear Explosion Monitoring R&D Program supports research by US National Laboratories, and universities and industry internationally to detect, locate, and identify nuclear detonations. This research program builds on the broad base of monitoring expertise developed over several decades. Annually the DOE and the US Department of Defense jointly solicit monitoring research proposals. Areas of research include: seismic regional characterization and wave propagation, seismic event detection and location, seismic identification and source characterization, hydroacoustic monitoring, radionuclide monitoring, infrasound monitoring, and

  19. Symposium on the 30th anniversary of the ZGS startup: Proceedings

    These proceedings document a number of aspects of a big science facility and its impact on science, on technology, and on the continuing program of a major US research institution. The Zero Gradient Synchrotron (ZGS) was a 12.5 GeV weak focusing proton accelerator that operated at Argonne for fifteen years--from 1964 to 1979. It was a major user facility which led to new close links between the Laboratory and university groups: in the research program; in the choice of experiments to be carried out; in the design and construction of beams and detectors; and even in the Laboratory management. For Argonne, it marked a major move from being a Laboratory dominated by nuclear reactor development to one with a stronger basic research orientation. The present meeting covered the progress in accelerator science, in the applications of technology pioneered or developed by people working at the ZGS, as well as in physics research and detector construction. At this time, when the future of the US research programs in science is being questioned as a result of the ending of the Cold War and plans to balance the Federal budget, the specific place of the National Laboratories in the spectrum of research activities is under particular examination. This Symposium highlights one case history of a major science program that was completed more than a decade ago--so that the further developments of both the science and the technology can be seen in some perspective. The subsequent activities of the people who had worked in the ZGS program as well as the redeployment of the ZGS facilities were addressed. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database

  4. Recommendations for Health Monitoring and Reporting for Zebrafish Research Facilities.

    Collymore, Chereen; Crim, Marcus J; Lieggi, Christine

    2016-07-01

    The presence of subclinical infection or clinical disease in laboratory zebrafish may have a significant impact on research results, animal health and welfare, and transfer of animals between institutions. As use of zebrafish as a model of disease increases, a harmonized method for monitoring and reporting the health status of animals will facilitate the transfer of animals, allow institutions to exclude diseases that may negatively impact their research programs, and improve animal health and welfare. All zebrafish facilities should implement a health monitoring program. In this study, we review important aspects of a health monitoring program, including choice of agents, samples for testing, available testing methodologies, housing and husbandry, cost, test subjects, and a harmonized method for reporting results. Facilities may use these recommendations to implement their own health monitoring program. PMID:26991393

  9. Long-Term Monitoring Research Needs: A DOE Perspective

    Moore, B.; Davis, C. B.

    2002-05-01

    The U.S. Department of Energy's Office of Environmental Management is responsible for dealing with the nation's legacy of Cold War radioactive and hazardous waste and contamination. Major efforts are underway to deal with this legacy; these are expected to last up to decades and cost up to billions of dollars at some sites. At all sites, however, active remediation must eventually cease; if hazards then remain, the site must enter into a long-term stewardship mode. In this talk we discuss aspects of long-term monitoring pertinent to DOE sites, focusing on challenges to be faced, specific goals or targets to be met, and research needs to be addressed in order to enable DOE to meet its long-term stewardship obligations. DOE LTM research needs fall into three major categories: doing what we can do now much more efficiently; doing things we cannot do now; and proving the validity of our monitoring programs. Given the enormity of the DOE obligations, it will be highly desirable to develop much more efficient monitoring paradigms. Doing so will demand developing autonomous, remote monitoring networks of in situ sensors capable of replacing (or at least supplementing to a large extent) conventional groundwater and soil gas sampling and analysis programs. The challenges involved range from basic science (e.g., inventing in situ sensors for TCE that do not demand routine maintenance) to engineering (attaining superior reliability in data reporting in remote networks) to ergonomics (developing decent ways of selecting and presenting the "right" information from the monitoring network) to regulatory affairs (presenting convincing evidence that the more efficient systems actually provide superior monitoring). We explore these challenges in some detail, focusing on the "long" in long-term monitoring as it applies to DOE sites. Monitoring system performance validation and, ultimately, regulator and stakeholder acceptance of site closure and long-term stewardship plans depend

    2010-04-01

    This paper presents an interim report on an international collaborative research project between the United States and Korea that fundamentally addresses the challenges associated with integrating structural health monitoring (SHM) system components into a comprehensive system for bridges. The objective of the project is to integrate and validate cutting-edge sensors and SHM methods under development for monitoring the long-term performance and structural integrity of highway bridges. A variety of new sensor and monitoring technologies have been selected for integration including wireless sensors, EM stress sensors and piezoelectric active sensors. Using these sensors as building blocks, the first phase of the study focuses on the design of a comprehensive SHM system that is deployed upon a series of highway bridges in Korea. With permanently installed SHM systems in place, the second phase of the study provides open access to the bridges and response data continuously collected as an internal test-bed for SHM. Currently, basic facilities including Internet lines have been constructed on the test-beds, and the participants carried out tests on bridges on the test road section owned by the Korea Expressway Corporation (KEC) with their own measurement and monitoring systems in the local area network environment. The participants were able to access and control their measurement systems by using Remote Desktop in Windows XP through Internet. Researchers interested in this test-bed are encouraged to join in the collaborative research.

    Two mini neutron monitors are installed at Concordia research station (Dome C, Central Antarctica, 75° 06' S, 123° 23' E, 3,233 m.a.s.l.). The site has unique properties ideal for cosmic ray measurements, especially for the detection of solar energetic particles: very low cutoff rigidity acceptance cones pointing to geographical latitudes > 75° S. The instruments consist of a standard neutron monitor and a "bare" (lead-free) neutron monitor. The instrument operation started in mid-January 2015. The barometric correction coefficients were computed for the period from 1 February to 31 July 2015. Several interesting events, including two notable Forbush decreases on 17 March 2015 and 22 June 2015, and a solar particle event of 29 October 2015 were registered. The data sets are available at cosmicrays.oulu.fi and nmdb.eu.

  1. USDA forest service global change research: Monitored ecosystems, northern linkages

    Foresters and natural resource managers have traditionally based long-term plans (i.e., 100+ year harvest cycles) on the assumption of stable landscapes and climate. Global climate change undercuts these assumptions and may alter or invalidate some accepted natural resource management practices and paradigms. Possible changes in biomass productivity, shifting of forest species' latitudinal or elevational limits, and rapid changes in forest community species and age class composition, all have major implications for management of the nation's forests. The USDA Forest Service is undertaking a national research program to assess rates, significant processes, and management implications of possible climatic change for the nation's forests and related resources. Pacific Region Forest Service global change research places major emphasis on understanding and monitoring forest processes in the northern boreal forest and the sub-arctic taiga of Alaska, which is potentially sensitive to climatic warming and to shifts in precipitation regime. A major terrestrial carbon pool, taiga forests and organic soils may also be important in the flux of greenhouse gases between landscape and atmosphere. Forest Service research emphasizes an ecosystem approach, incorporating landscape- and watershed-level field research with smaller-scale studies of forest ecosystem response mechanisms. Ecological monitoring is critical, and includes establishment of a monitoring mega-transect from northern latitudinal tree line to mediterranean/dry temperate forest/shrublands. Emphasis is placed on the most critical Pacific Region ecosystems: northern boreal forest (taiga), moist temperate forest, and mediterranean/dry temperate forest (chaparral/southern Ponderosa pine)

    IceCube Collaboration; Ackermann, M.

    2007-11-02

    This paper bundles 40 contributions by the IceCube collaboration that were submitted to the 30th International Cosmic Ray Conference ICRC 2007. The articles cover studies on cosmic rays and atmospheric neutrinos, searches for non-localized, extraterrestrial {nu}{sub e}, {nu}{sub {mu}} and {nu}{sub {tau}} signals, scans for steady and intermittent neutrino point sources, searches for dark matter candidates, magnetic monopoles and other exotic particles, improvements in analysis techniques, as well as future detector extensions. The IceCube observatory will be finalized in 2011 to form a cubic-kilometer ice-Cherenkov detector at the location of the geographic South Pole. At the present state of construction, IceCube consists of 52 paired IceTop surface tanks and 22 IceCube strings with a total of 1426 Digital Optical Modules deployed at depths up to 2350 m. The observatory also integrates the 19 string AMANDA subdetector, that was completed in 2000 and extends IceCube's reach to lower energies. Before the deployment of IceTop, cosmic air showers were registered with the 30 station SPASE-2 surface array. IceCube's low noise Digital Optical Modules are very reliable, show a uniform response and record waveforms of arriving photons that are resolvable with nanosecond precision over a large dynamic range. Data acquisition, reconstruction and simulation software are running in production mode and the analyses, profiting from the improved data quality and increased overall sensitivity, are well under way.

    Organotypic three-dimensional (3D) cell culture models have the potential to act as surrogate tissues in vitro, both for basic research and for drug discovery/toxicology. 3D cultures maintain not only 3D architecture but also cell-cell and cell extracellular matrix interactions, particularly when grown in cysts or spheroids. Characterization of cell cultures grown in 3D formats, however, provides a significant challenge for cell biologists due to the incompatibility of these structures with commonly found optical or electronic monitoring systems. Electronic impedance spectroscopy is a cell culture monitoring technique with great potential; however, it has not been possible to integrate 3D cultures with commercially available systems to date. Cyst-like 3D cultures are particularly challenging due to their small size and difficulty in manipulation. Herein, we demonstrate isolation of cyst-like 3D cultures by capillarity and subsequent integration with the organic electrochemical transistor for monitoring the integrity of these structures. We show not only that this versatile device can be adapted to the cyst format for measuring resistance and, therefore, the quality of the cysts, but also can be used for quantitative monitoring of the effect of toxic compounds on cells in a 3D format. The ability to quantitatively predict effects of drugs on 3D cultures in vitro has large future potential for the fields of drug discovery and toxicology.

  4. Gamma monitoring system 'Hyperion' at the research nuclear reactor RB

    While performing experiments at the research reactor RB at Vinca institute it is mandatory to measure the intensity of gamma radiation at reactor RB since the reactor has no biological protection. the stationary distributed measurement system 'Hyperion' implemented at reactor RB, performs measurements and monitoring of gamma radiation at 10 specified measuring sites within and in the vicinity of the reactor RB in the required absorbed dose in air range of 50 nGy/h to 10 mGy/h. the 'Hyperion' monitoring system have three hierarchically organized layers. the basic layer consists of the network of 10 intelligent gm probes located at predetermined measuring sites. the medium layer represents the PC-based local control node where measured data from all intelligent probes are separately acquired, stored in the local database and processed for local visualization and printed measurements reports for network operator. the information on the status of the intelligent gm probes are also provided, enabling the verification of measured results at the local control node. the central control node represents the pc-based highest monitoring network layer connected to the local control node using already existing lan infrastructure. the central control node hosts the central database, provides full insight into instantaneous gamma radiation levels at all measuring sites, provides archives on daily bases for all monitored locations and printed reports on measurements for all measuring sites at any time of gamma radiation measurement.

  5. On-line tritium monitoring in research reactor Dhruva

    Dhruva is 100 MW (Th) research reactor. Heavy water is used as a coolant, moderator and reflector. Tritium is one of the gaseous effluents released from 100 meter stack. During reactor operation, tritium release is approximately 135 GBqd-1 with a concentration of ∼ 90-100 KBqm-3 (0.33 DAC) and in shutdown condition it is slightly higher and depends upon the heavy water related jobs. Continuous sampling of the exhaust air is carried out using bubbler method and samples are analyzed once in a day to estimate the tritium release during the period. Due to energy interference, it is not possible to monitor tritium in presence of 41Ar using continuous tritium monitor in normal sampling method. Detection of tritium in the presence of other radionuclides is a particular challenge since radiation from these species masks detector response for tritium. In Dhruva main interfering radionuclides is 41Ar which is produced due to activation of 40Ar present in air (∼ 1 %) while cooling shutoff rod assemblies and depends upon reactor power. Concentration of 41Ar in exhaust air is 34.1 MBqm3 at 100 MW. This paper describes the setup proposed for online tritium monitoring using multi-line continuous tritium monitor developed by RSSD

  7. Monitoring and reviewing research reactor safety in Australia

    Th research reactors operated by the Australian Nuclear Science and Technology Organization (ANSTO) comprise the 10 MW reactor HIFAR and the 100 kW reactor Moata. Although there are no power reactors in Australia the problems and issues of public concern which arise in the operation of research reactors are similar to those of power reactors although on a smaller scale. The need for independent safety surveillance has been recognized by the Australian Government and the ANSTO Act, 1987, required the Board of ANSTO to establish a Nuclear Safety Bureau (NSB) with responsibility to the Minister for monitoring and reviewing the safety of nuclear plant operated by ANSTO. The Executive Director of ANSTO operates HIFAR subject to compliance with requirements and arrangements contained in a formal Authorization from the Board of ANSTO. A Ministerial Direction to the Board of ANSTO requires the NSB to report to him, on a quarterly basis, matters relating to its functions of monitoring and reviewing the safety of ANSTO's nuclear plant. Experience has shown that the Authorization provides a suitable framework for the operational requirements and arrangements to be organised in a disciplined and effective manner, and also provides a basis for audits by the NSB by which compliance with the Board's safety requirements are monitored. Examples of the way in which the NSB undertakes its monitoring and reviewing role are given. Moata, which has a much lower operating power level and fission product inventory than HIFAR, has not been subject to a formal Authorization to date but one is under preparation

  8. Wireless condition monitoring for the RA-6 research reactor

    The vibration laboratory at C.A.B. has a great experience with the analysis and diagnostic of symptoms of failures in the rotating equipment of the R-6 research reactor and in our longest NPP (CANDU 600 Mw), located in Embalse town, Cordoba City, Argentina. Objective: The standard condition monitoring instrumentation system were designed for large equipment operating under different environmental conditions and sensitivities. The signal processing is not flexible and the diagnostic is an expensive method for the small poll type research reactors. This papers describes the research and development which are related whit the new concept, cheaper and flexible condition monitoring instrumentation system. Implementing a vibration analysis measurements technique with a sensor inside (in the pool) of the nuclear reactor RA-6, and mainly based on fft signal processing, an extensive program for vibration source identification was done. Different nuclear power conditions were monitored as full power and in zero power, also. This zero power shows the best acoustical environmental, because the cooling pumps are stop, and the core is cooling by natural convection. Two sensors were mainly used as the detector's subsystem. One of these detectors was an accelerometer attached to the top of the fine control rod and the other one was a water resistant omnidirectional microphone which was located underwater at different distances from the nuclear core. All the signal measurement by this two sensors were recorded and then was processed. Both signal was acquired at the same time for correlation analysis purposes. The analysis was composed by a 'Spectral Dynamics SD380' connected to a P.C. with dedicated post processing software. On the other hand, some calibration and sensitivity comparison was done using an SKFCM40, dual channel data collector and analyzer. (author)

  9. Market research on garment-based "wearables" and biophysical monitoring and a new monitoring method.

    Schultze, Claudia; Burr, Stacey

    2004-01-01

    Technology advancements are foremost on the minds of scientists and developers who are working to overcome the many hurdles associated with bringing consumers the enhanced benefits associated with next generation wearable health systems. Often the technology work takes a front seat to the basic requirements of traditional consumer apparel. The choices of what consumers elect to place and carry on their body can be practical, logical, emotional and sometimes seemingly random. By providing insights and data to support the claims, developers of wearable health systems of the future will be able improve their chance of consumer adoption and continued use by gaining a clearer picture of the people that will be wearing the systems. Results from 5 different consumer research studies are presented, examining consumer buying patterns, gender differences, regional differences, their receptivity to health benefits delivered via clothing and what they want from technology enhanced clothing. Market research related to biophysical monitoring utilizing smart fabrics or interactive textiles show a critical level of commercial activity. Medical applications focused on the aged, infant and critical patient care are taking the lead. This paper presents a look at the biophysical monitoring market and discusses new materials useful in garment systems and the challenges remaining for their development and integration with textiles. A new method of non-invasive monitoring of periodic activity is discussed. PMID:15718637

  10. Environmental and effluent monitoring at Lucas Heights Research Laboratories, 1994

    Results are presented of environmental and effluent monitoring conducted in the vicinity of the Lucas Heights Research Laboratories (LHRL) during 1994. All low level liquid and gaseous effluent discharges complied with existing discharge authorisations and relevant environmental regulations. Potential effective doses to the general public from controlled airborne discharges during this period, were estimated to be less than 0.015 mSv/year for receptor locations on the 1.6 km buffer zone boundary around HIFAR. This value represents 1.5 % of the 1 mSv/year dose limit for long term exposure that is recommended by the National Health and Medical Research Council, and 5 % of the site dose constraint of 0.3 mSv/year adopted by ANSTO. 27 refs., 22 tabs., 6 figs

  11. Future Research Needs for Long-Term Monitoring Program Design

    Minsker, B. S.; Dougherty, D. E.; Williams, G.; Davis, C. B.

    2002-05-01

    An ASCE Task Committee is preparing a manual of practice on long-term monitoring (LTM) program design for groundwater (including vadose) systems. The committee has identified several areas for future research and technology transfer that will improve LTM design. LTM is an on-going activity aimed at assessing remediation performance, containment integrity, and/or continued non-contamination of the subsurface and groundwater. LTM has different goals and needs than site characterization, so data collection, analysis, and modeling approaches must evolve to meet these new needs. Many new sensors and field measurement methods for LTM are under development, and research is needed to develop methods to integrate these data sources with more traditional samples drawn from wells to maximize the information extracted from the data. These new methods need to be able to provide information to assess performance of waste management activities and to understand long-term behavior by optimizing the collection and analysis of multiple data types. The effects of different sampling and measurement methods on monitoring results and their implications for the design of LTM programs also require study. Additional research needs include development of methods to assess flow control strategies, to identify monitoring redundancy in fractured media, and to better incorporate uncertainty into the LTM design process. Well-tested, documented, and open datasets are needed to validate and compare the performance of methods. Technology transfer activities must address the need for evolution of regulatory guidance to encompass the types of data analysis that are needed to assess remediation or containment performance, to identify appropriate LTM plans, and to incorporate novel data collection methods that may support better decision quality through the use of more extensive measurements with lower individual precisions than traditional measurements or may measure an indicator parameter rather than

  12. Monitoring for global change in Alaska research natural areas

    The prospect of a significant shift in climatic equilibria and changes in atmospheric composition raises concerns about the potential decline of important natural resources and threats to the survival of the complete range of natural diversity. Three elements are needed in any program with a focus on such concerns: (1) a network of sites containing examples of all or most of the diversity; (2) testable hypotheses of mechanisms by which global change effects will occur in real ecosystems; and (3) a monitoring program robust enough to detect the changes at the sites. With such a program, hypotheses of global change effects can be accepted, rejected, or modified. The Alaska Research Natural Area (RNA) network has been selected to encompass natural diversity. It contains sites and some modest data sets that offer insights into possible effects and outcomes of global warming. Geothermally heated soils at Clear Creek Hot Springs and Big Windy Hot Springs RNAs offer a possible model of forest growth under a warmer climate. On the other hand, a warmer climate may allow greater winter survival of forest insects and increase in forest mortality, similar to that which killed 19% of the trees in a forest reference monitoring plot in 1989 in a mature white spruce stand in the Bonanza Creek Long-Term Ecological Research site. Even if global warming proves to be modest, the program of selecting and monitoring natural diversity according to global change hypotheses is justified because it will contribute greatly to an improved understanding of functioning and linkages among earth systems and because widespread, human-caused reductions in biological diversity have already occurred and are accelerating

  13. Environmental monitoring program of a nuclear research institute

    The main activities of the CDTN Research Institute are concentrated in the areas of reactors, materials, process engineering, the environment, health, radioprotection, radioactive waste, and applied physics. Its Environmental Monitoring Program (EMP) began in 1985 with the objective of evaluating and controlling its installations' operating conditions as well as the impact on the neighboring environment caused by release of stable and radioactive elements. EMP's adequate planning and management resulted in obtaining an unique database that has generated information which have contributed to improving the credibility of nuclear and non-nuclear activities developed by the Center with the local community. Besides this, the data collection, study and continuous and systematic follow-up processes of environmental variables allowed the Center to be one of the Nation's pioneering research institutions in obtaining an Environmental Operating License from the Brazilian Environment and Natural Resources Institute (IBAMA). The objective of the present work is to present the experience acquired during the years, including a discussion about methodologies employed as well as the importance of using statistical evaluation tools in evaluating, interpreting, and controlling the quality of the results. Liquid effluent control and surface water monitoring results are also presented. (author)

  18. Development of a risk monitor for research reactor

    The traditional approach to engineering asset management, which primarily includes management and operation and maintenance activities, in a nuclear plant is based on engineering judgment. Here, the defence-in-depth and conservative criteria form the basis of decisions. Ideally, it is expected that the decisions should be based on performance of systems, structures and components (SSC), which should also take plant safety margin into consideration. Probabilistic methods are widely used as a compliment to deterministic methods in assessing safety of nuclear reactors. A risk-based operations and maintenance management system has been developed for a research reactor. The results of a level-1 PSA study in terms of minimal cut-set equations along with other engineering plant information forms major input for this system. The system is expected to be operational in plant control room conditions in support of routine decisions. This paper presents one of the main applications of the plant Level-1 Probabilistic Safety Assessment, developed from plant specific data i.e. a risk monitor. The risk monitor has several applications that support in decision making. It is expected that the use of this system in real-time scenario will provide improved understanding of safety on one hand while enabling enhancement of plant economics on the other. Some the case studies are discussed here. (author)

    The Kurile-Kamchatka-Alaska portion of the Pacific Rim of Fire spans for nearly 5400 km. It includes more than 80 active volcanoes and averages 4-6 eruptions per year. Resulting ash clouds travel for hundreds to thousands of kilometers defying political borders. To mitigate volcano hazard to aviation and local communities, the Alaska Volcano Observatory (AVO) and the Institute of Volcanology and Seismology (IVS), in partnership with the Kamchatkan Branch of the Geophysical Survey of the Russian Academy of Sciences (KBGS), have established a collaborative program with three integrated components: (1) volcano monitoring with rapid information exchange, (2) cooperation in research projects at active volcanoes, and (3) volcanological field schools for students and young scientists. Cooperation in volcano monitoring includes dissemination of daily information on the state of volcanic activity in neighboring regions, satellite and visual data exchange, as well as sharing expertise and technologies between AVO and the Kamchatkan Volcanic Eruption Response Team (KVERT) and Sakhalin Volcanic Eruption Response Team (SVERT). Collaboration in scientific research is best illustrated by involvement of AVO, IVS, and KBGS faculty and graduate students in mutual international studies. One of the most recent examples is the NSF-funded Partnerships for International Research and Education (PIRE)-Kamchatka project focusing on multi-disciplinary study of Bezymianny volcano in Kamchatka. This international project is one of many that have been initiated as a direct result of a bi-annual series of meetings known as Japan-Kamchatka-Alaska Subduction Processes (JKASP) workshops that we organize together with colleagues from Hokkaido University, Japan. The most recent JKASP meeting was held in August 2011 in Petropavlovsk-Kamchatsky and brought together more than 130 scientists and students from Russia, Japan, and the United States.

    Background On site monitoring of research is one of the most effective ways to ensure compliance during research conduct. However, it is least carried out primarily for two reasons: presumed high costs both in terms of human resources and finances; and the lack of a clear framework for undertaking site monitoring. In this paper we discuss a model for research site monitoring that may be cost effective and feasible in low resource settings. Methods This was a retrospective review of research s...

  2. Gas bubble disease monitoring and research of juvenile salmonids

    This document describes the project activities 1996--1997 contract year. This report is composed of three chapters which contain data and analyses of the three main elements of the project: field research to determine the vertical distribution of migrating juvenile salmonids, monitoring of juvenile migrants at dams on the Snake and Columbia rivers, and laboratory experiments to describe the progression of gas bubble disease signs leading to mortality. The major findings described in this report are: A miniature pressure-sensitive radio transmitter was found to be accurate and precise and, after compensation for water temperature, can be used to determine the depth of tagged-fish to within 0.32 m of the true depth (Chapter 1). Preliminary data from very few fish suggest that depth protects migrating juvenile steelhead from total dissolved gas supersaturation (Chapter 1). As in 1995, few fish had any signs of gas bubble disease, but it appeared that prevalence and severity increased as fish migrated downstream and in response to changing gas supersaturation (Chapter 2). It appeared to gas bubble disease was not a threat to migrating juvenile salmonids when total dissolved gas supersaturation was < 120% (Chapter 2). Laboratory studies suggest that external examinations are appropriate for determining the severity of gas bubble disease in juvenile salmonids (Chapter 3). The authors developed a new method for examining gill arches for intravascular bubbles by clamping the ventral aorta to reduce bleeding when arches were removed (Chapter 3). Despite an outbreak of bacterial kidney disease in the experimental fish, the data indicate that gas bubble disease is a progressive trauma that can be monitored (Chapter 3)

  3. Passive and Active Monitoring on a High Performance Research Network

    The bold network challenges described in ''Internet End-to-end Performance Monitoring for the High Energy and Nuclear Physics Community'' presented at PAM 2000 have been tackled by the intrepid administrators and engineers providing the network services. After less than a year, the BaBar collaboration has collected almost 100 million particle collision events in a database approaching 165TB (Tera=1012). Around 20TB has been exported via the Internet to the BaBar regional center at IN2P3 in Lyon, France, for processing and around 40 TB of simulated events have been imported to SLAC from Lawrence Livermore National Laboratory (LLNL). An unforseen challenge has arisen due to recent events and highlighted security concerns at DoE funded labs. New rules and regulations suggest it is only a matter of time before many active performance measurements may not be possible between many sites. Yet, at the same time, the importance of understanding every aspect of the network and eradicating packet loss for high throughput data transfers has become apparent. Work at SLAC to employ passive monitoring using netflow and OC3MON is underway and techniques to supplement and possibly replace the active measurements are being considered. This paper will detail the special needs and traffic characterization of a remarkable research project, and how the networking hurdles have been resolved (or not) to achieve the required high data throughput. Results from active and passive measurements will be compared, and methods for achieving high throughput and the effect on the network will be assessed along with tools that directly measure throughput and applications used to actually transfer data

    ZHAO Xin-ze; YAN Xin-ping; ZHAO Chun-hong; GAO Xiao-hong; XIAO Han-liang

    2004-01-01

    Oil monitoriug and vibration monitoring are two principal techniques for mechanical fault diagnosis and condition monitoring at present. They monitor the mechanical condition by different approaches, neverthelcss, oil and vibration monitoring are related in information collecting and processing. In the same mechanical system, the information obtained from the same information source can be described with the same expression form. The expressions are constituted of a structure matrix, a relative matrix and a system matrix. For oil and vibration monitoring, the information source is correlation and the collection is independent and complementary. And oil monitoring and vibration monitoring have the same process method when they yield their information. This rcsearch has provided a reasonable and useful approach to combine oil monitoring and vibration monitoring.

  15. Progress report of Physics Division. 1st October 1977 - 30th September 1978. Acting Division Chief - Mr. W. Gemmell

    Two main features influenced the year's activities: the Government's constraints on staffing and the Commission's views on research and development objectives. The reduction in staff numbers in Physics Division was by natural wastage, chiefly in the technical officer area. This has reduced operation of the reactor to a major extent and of the accelerator, both of which are now somewhat under-staffed and inadequately serviced. The second influence was the view of the Commission that research activities should move away from the more traditional areas of nuclear energy towards problems of the front end of the fuel cycle and the environment. Also, the Commission decided to place increasing emphasis on fusion and possibly on alternative energy studies. Neutron capture studies were continued, mainly in collaboration with Oak Ridge National Laboratory, Brookhaven National Laboratory and Bruyires-le-Chgtel and, to a lesser extent, the Australian universities, with the objective of improving our understanding of the capture mechanism and of seeking applications of the results and techniques developed in the neutron capture research. Results from the measurement of the 252Cf spontaneous fission neutron spectrum are now available in reasonably final form. other fission work was concerned with the shape of the fission barriers for the thorium isotopes and with confirming differences between the 0+ and 1+ resonances of 239Pu. Commercial acceptance of the delayed neutron method of analyzing ore samples for uranium continued to gain ground. There was interest in the possibility of a similar service for thorium and the advantages of nuclear techniques of analysis became more widespread. Several of these techniques (backscattering, proton induced X-ray emission (PIXE), fission track) were actively developed. The major restraint was unavailability of staff. Particularly interesting was the coloration produced by proton irradiation of natural fluorite crystals. This coloration

    Institute for High Energy Physics (in the framework of the National Research Centre Kurchatov Institute) is organizing the XXX-th International Workshop on High Energy Physics Particle and Astroparticle Physics, Gravitation and Cosmology: Predictions, Observations and New Projects, June 23-27, 2014, in Protvino, Moscow region, Russia. The purpose of this Workshop is to exhibit a more complete and coherent picture of our understanding of the structure and dynamics of the microcosm, the megacosm and its evolution and the relationship between these two extremes of modern physics. The Workshop covers both theory and experiment/observations in most actual and critical points. We would like to promote, at the meeting, much more critical discussions than is usually the case. We strive to make the meeting not only informative but also to give it a truly working character with the aim to elaborate meaningful and clear conclusions about the actual state of affairs in the main areas of high-energy particle and ast...

  17. Progress report of Physics Division. 1st October 1975 - 30th September 1976. Acting Division Chief - Mr. W. Gemmell

    The official Inquiry into Environmental Aspects of Uranium Mining by Mr. Justice Fox has had a major influence on this year's work. The reduction in uranium exploration expenditure has reduced demand for service work, much time has been spent providing information in connection with submissions to the Inquiry and it has had an unsettling effect on research. However, there has been a gratifying increase in the number of enquiries on the availability of nuclear techniques to solve industrial and research problems. Cooperation with Oak Ridge National Laboratory on analysis and interpretation of neutron capture cross sections has continued. Scientific interest has continued to revolve around those isotopes with almost closed shell configurations. An additional capture mechanism of the single particle character over and above the valence capture mechanism is required to explain the observed correlations. Much time has been devoted to finding Strutinsky barrier parameters which would provide an adequate description of both the fission cross section and fission fragment angular distribution of 232Th. A reasonably satisfactory quantitative fit was achieved using a three humped potential barrier. ν-bar measurements for 232Th revealed no deviation from linearity with energy up to 16 MeV, and ν-bar measurements on 230Th failed to reveal the expected increase in ν-bar as the transition over the fission barrier was made. Improved measurements of neutron emission from 252Cf spontaneous fission fragments has confirmed the structure due to even-odd charge effects. The study of SPERT transients was completed with calculations of the series of forced coolant flow transients. The physics of transient heat flow is now being examined. We have participated in the international comparison of calculations on Standard Loss of Coolant problems, using NAIAD. While Standard Problem 3 presented no difficulties, the re-flooding aspects of the emergency core cooling in Standard Problem 4

  18. Foreign Travel Trip Report for LLNL travel with DOE FES funding, May 19th-30th, 2012

    I attended the 20th biannual International Conference on Plasma Surface Interaction (PSI) in Fusion Devices in Aachen, Germany, hosted this year by the Forschungszentrum Julich (FZJ) research center. The PSI conference is one of the main international forums for the presentation and discussion of results on plasma surface interactions and edge plasma physics relevant to magnetic confinement fusion devices. I disseminated the recent results of FESP/LLNL tokamak research by presenting three posters on: (i) understanding reconnection and controlling edge localized modes (ELMs) using the BOUT++ code, (ii) simulation of resistive ballooning mode turbulence, and (iii) innovative design of Snowflake divertors. I learned of many new and recent results from international tokamak facilities and had the opportunity for discussion of these topics with other scientists at the poster sessions, conference lunches/receptions, etc. Some of the major highlights of the PSI conference topics were: (1) Review of the progress in using metallic tungsten and beryllium (ITER-like) walls at international tokamak facilities: JET (Culham, UK), TEXTOR (FZJ, Germany) and Alcator CMOD (MIT, USA). Results included: effect of small and large-area melting on plasma impurity content and recovery, expected reduction in retention of hydrogenic species, increased heat load during disruptions and need for mitigation with massive gas injection. (2) A review of ELM control in general (T. Evans, GA) and recent results of ELM control using n=2 external magnetic perturbations on ASDEX-Upgrade (MPI-Garching, Germany). (3) General agreement among the international tokamak database that, along the outer midplane of a low collisionality tokamak, the SOL power width in current experiments varies inversely with respect to plasma current (Ip), roughly as 1/Ip, with little dependence on other plasma parameters. This would imply roughly a factor of 1/4 of the width that was assumed for the design of the ITER tokamak

  19. Artificial neural network for research reactor safety status monitoring

    During reactor upset/abnormal conditions, emphasis is placed on plant operator's ability to quickly identify the problem and perform diagnosis and initiate recovery action to ensure safety of the plant. However, the reliability of human action is adversely affected at the time of crisis, due to the time stress and psychological factors. Availability of operational aids capable of monitoring the status of the plant and quickly identifying the deviation from normal operation is expected to significantly improve the operator reliability. Artificial Neural Network (based on Back Propagation Algorithm) has been developed and applied for reactor safety status monitoring, as part of an Operator Support System. ANN has been trained for 14 different plant states using 42 input symptom patterns. Recall tests performed on the ANN show that the system was able to identify the plant state with reasonable accuracy. (author)

    Each summer fires rage through European forests, burning hundreds of thousands of hectares per year, as a result of the many (up to 60000) forest fires that usually occur annually in Europe. Fires can threaten public health and safety, destroy property and cause economic damages. Despite of their medium extension (the average burnt area is less than 6 ha), much smaller if compared with other regions like the USA and Canada, the number of simultaneous active fires in Europe can be very high, fomented by weather conditions that, especially in summer times and for countries of South Europe, are particularly favourable to a rapid and dramatic development of flames. Fires still are not only a social problem, but also an environmental emergency, producing a continuous impoverishment of forests and possibly indirectly triggering other natural hazards (e.g. making slopes, without the trees action, more prone to landslides). Additionally, there is a general concern about the loss of biodiversity and the contribution to land degradation that fires may cause. Earth Observation satellite systems have been largely tested for fire detection and monitoring from space. Their spectral capability, synoptic view and revisit times can offer an added value in the operational use not only in real time, during fires fighting activities, but also in near-real or delay time during the phases of risk management and mitigation. However, the practice of an actual operational use of satellite products by end-users is still not usual at European level. This work is based on the experience carried out jointly by CNR-IMAA and the National Civil Protection Department (DPC), in the framework of a five-year agreement in which the operational use of an Earth observation satellite system for fires spotting and monitoring is tested. Satellite-based products, developed not only for detecting fires but also for continuously monitoring their evolution in time domain, have been provided to Civil Protection

    Cyanobacteria bloom is a great ecological problem of Curonian Lagoon and Baltic Sea. The development of novel methods for the on-line control of cyanobacteria concentration and, moreover, for prediction of bloom spreading is of interest for monitoring the state of ecosystem. Here, we report the results of the joint application of hyperspectral measurements and remote sensing of Curonian Lagoon in July 2015 aimed at the assessment of cyanobacteria communities. We show that hyperspectral data allow on-line detection and qualitative estimation of cyanobacteria concentration, while the remote sensing data indicate the possibility of cyanobacteria bloom detection using the spectral features of upwelling irradiation.

    Liu, Lu; Liao, Xiao-qing; Zhu, Yong-kang; Yang, Wei; Zhang, Pei; Zhao, Yong-kai; Huang, Hui-jie

    2013-09-01

    In textile production, quality control and testing is the key to ensure the process and improve the efficiency. Defect of the knitting needles is the main factor affecting the quality of the appearance of textiles. Defect detection method based on machine vision and image processing technology is universal. This approach does not effectively identify the defect generated by damaged knitting needles and raise the alarm. We developed a knitting needle status monitoring setup using optical imaging, photoelectric detection and weak signal processing technology to achieve real-time monitoring of weaving needles' position. Depending on the shape of the knitting needle, we designed a kind of Glass Optical Fiber (GOF) light guides with a rectangular port used for transmission of the signal light. To be able to capture the signal of knitting needles accurately, we adopt a optical 4F system which has better imaging quality and simple structure and there is a rectangle image on the focal plane after the system. When a knitting needle passes through position of the rectangle image, the reflected light from needle surface will back to the GOF light guides along the same optical system. According to the intensity of signals, the computer control unit distinguish that the knitting needle is broken or curving. The experimental results show that this system can accurately detect the broken needles and the curving needles on the knitting machine in operating condition.

  16. Research on Overflow Monitoring Mechanism Based on Downhole Microflow Detection

    2014-01-01

    Full Text Available The flow rate variation of the drilling fluid and micro-overflow loss is difficult to analyze. The purpose to prevent the occurrence of kick, lost circulation, and other complex conditions is not easy to be achieved. Therefore, the microflow-induced annulus multiphase flow rate and annulus pressure field model were studied, and a downhole microflow measurement system has been developed. A differential pressure type flow measurement was used in the system, and real-time downhole information was obtained to achieve deep, narrow windows and other safety-density complex formation security. This paper introduced a new bottom-hole flow meter which can measure the annular flux while drilling and monitor overflow and circulation loss. The accuracy and reliability of the MPD (managed pressure drilling system can be improved obviously by applying the device; as a result, the safety of drilling is enhanced and the cost is reduced.

  17. A meta-database comparison from various European Research and Monitoring Networks dedicated to forest sites

    2013-01-01

    Full Text Available Of a wide variety of international forest research and monitoring networks, several networks are dedicated to the effects of climate change on forests, while the effects of anthropogenic pollutants on forests have been a major area for both monitoring and research for decades. The large amounts of data already obtained within existing monitoring programmes and large-scale international projects can be used to increase understanding of the state and potential of forest mitigation and adaptation to climate change in a polluted environment, and a major challenge now is to evaluate and integrate the presently available databases. We present a meta-database with the main goal to highlight available data and integrate the information about research and monitoring of selected European Research and Monitoring Networks (ERMNs. Depending on the selected ERMNs, the list of variables and the measurement units differ widely in the databases. As a result, activities related to the identification, evaluation and integration of the presently available databases are important for the scientific community. Furthermore, and equally important, the recognition of current knowledge gaps and future needed research is made easier. This analysis suggests that: ground-level ozone is under-investigated, although it is one of the pollutants of greatest concern to forests; in addition to CO2, long-term other greenhouse gasses (GHG flux measurements should be carried out; there is still a need of improving links between monitoring of atmospheric changes and impacts on forests; research-oriented manipulative experiments in the forests are missing.

    Computerized tritium monitoring is now in use at the Tritium Research Laboratory (TRL). Betatec 100 tritium monitors, along with several Sandia designed accessories, have been combined with a PDP 11/40 computer to provide maximum personnel and environmental protection. Each individual monitoring system, in addition to a local display in the area of interest, has a visual/audible display in the control room. Each system is then channeled into the PDP 11/40 computer, providing immediate assessment of the status of the entire laboratory from a central location. Measurement capability ranges from uCi/m3 levels for room air monitoring to KCi/m3 levels for glove box and process system monitoring. The overall monitoring system and its capabilities will be presented

  19. Research and Development for the Mu2e Extinction Monitor

    Mott, Casey Benjamin [Northern Illinois U.

    2016-01-01

    Mu2e is a planned experiment to search for flavor-violating conversion from a muon to an electron. The experiment will use a pulsed 8 GeV proton beam to produce muons which will then stop in an aluminum target. Mu2e will search for the $\\mu^- + Al \\rightarrow e^- + Al$ process. For Mu2e, an extinction rate of 10$^{-10}$ is required to reduce the backgrounds to an acceptable level. Extinction is the ratio of the amount of protons striking the production target between beam pulses to the number striking it during the beam pulse. One of the backgrounds, off-target interactions, was simulated using G4beamline and Fermilab's Grid setup to confirm that an extinction rate of 10$^{-10}$ is possible. The extinction level will be measured by the extinction monitor which will include scintillation counters read out by photomultiplier tubes. In order to build a beam time profile, low fake responses (after pulses) are needed in the photomultiplier tubes. This thesis determines the best combination of resistors, voltage, and other components that provide the lowest after pulse rate.

    1993-01-01

    A remote sensing research agenda designed to expand the knowledge of the spatial distribution of species richness and its ecological determinants and to predict its response to global change is proposed. Emphasis is placed on current methods of mapping species richness of both plants and animals, hypotheses concerning the biophysical factors believed to determine patterns of species richness, and anthropogenic processes causing the accelerating rate of extinctions. It is concluded that biodiversity should be incorporated more prominently into the global change and earth system science paradigms.

  2. Device-based monitoring in physical activity and public health research

    Measurement of physical activity is important, given the vital role of this behavior in physical and mental health. Over the past quarter of a century, the use of small, non-invasive, wearable monitors to assess physical activity has become commonplace. This review is divided into three sections. In the first section, a brief history of physical activity monitoring is provided, along with a discussion of the strengths and weaknesses of different devices. In the second section, recent applications of physical activity monitoring in physical activity and public health research are discussed. Wearable monitors are being used to conduct surveillance, and to determine the extent and distribution of physical activity and sedentary behaviors in populations around the world. They have been used to help clarify the dose–response relation between physical activity and health. Wearable monitors that provide feedback to users have also been used in longitudinal interventions to motivate research participants and to assess their compliance with program goals. In the third section, future directions for research in physical activity monitoring are discussed. It is likely that new developments in wearable monitors will lead to greater accuracy and improved ease-of-use. (paper)

  8. VAMOS: The verification and monitoring options study: Current research options for in-situ monitoring and verification of contaminant remediation and containment within the vadose zone

    The Verification and Monitoring Options Study Project (VAMOS) was established to identify high-priority options for future vadose-zone environmental research in the areas of in-situ remediation monitoring, post-closure monitoring, and containment emplacement and verification monitoring. VAMOS examined projected needs not currently being met with applied technology in order to develop viable monitoring and verification research options. The study emphasized a compatible systems approach to reinforce the need for utilizing compatible components to provide user friendly site monitoring systems. To identify the needs and research options related to vadose-zone environmental monitoring and verification, a literature search and expert panel forums were conducted. The search included present drivers for environmental monitoring technology, technology applications, and research efforts. The forums included scientific, academic, industry, and regulatory environmental professionals as well as end users of environmental technology. The experts evaluated current and future monitoring and verification needs, methods for meeting these needs, and viable research options and directions. A variety of high-priority technology development, user facility, and technology guidance research options were developed and presented as an outcome of the literature search and expert panel forums

    1974-07-01

    For determining ionium ({sup 2}30Th) in minerals and uranium processing wastes by precipitation with fluorhidric acid, using lanthanum as carrier, and selective extraction with tenoytrifluoroacetone (TTA) followed by radiometric determination of the isolated nuclide, it is necessary the use of a tracer since the chemical yield of the separation ranges between wide limits. In this paper, the use of the beta-emitter {sup 2}34Th as the most convenient tracer is discussed. Equations are derived for correcting for counting errors introduced by other thorium isotopes which are present either in the sample or in the tracer, as well as for calculating the chemical yield of the separation. These equations have been experimentally checked by ionium determinations carried out with different types of samples. (Author) 18 refs.

  10. Theoretical research on construction quality real-time monitoring and system integration of core rockfill dam

    2009-01-01

    With the enlargement of core rockfill dam construction scale and the improvement of construction mechanization level, the traditional manual construction quality control method is now difficult to meet the quality and safety demands of modern dam construction, so automatic and real-time dam construction quality monitoring with high-techs is urgently needed. The paper makes theoretical research on construction quality real-time monitoring and system integration of core rockfill dam, proposes implementation method and integrated solution of construction quality real-time monitoring of core rockfill dam construction process, realizes refining, all-whether, entire-process and real-time control and analysis on key links of dam construction, and introduces the application of the construction quality real-time monitoring and system integration technology to a practical core rockfill dam project.

  11. Research on fiber-based portable large area surface contamination monitor

    Large area portable surface contamination monitor is suitable searching the hot point, especially in the situations of large contamination area such as work site radioactive monitoring, nuclear facility decommissioning or nuclear emergency response. This paper focus on beta radioactive surface contamination. Through researching upon the detector which is made of large area plastic scintillation coupled with fibers, the first large area plastic scintillation surface contamination monitor was established. The effective area of detector reaches 1200 cm2. The verifying experiments indicates that the detection efficiency to 90Sr-90Y plate source comes to 7%. The results show this kind of detector is competent for beta radioactive surface contamination. This work laid a foundation for research and development of the relative instrument. (authors)

  12. Keep Talking & Monitoring: the importance of longitudinal research & community-based monitoring to support sustainable land management in southern Africa

    Dougill, Andrew; Stringer, Lindsay

    2015-04-01

    Projects come and go with researchers, development practioners and government staff initiating new forms of community engagement in environmental monitoring and land management practices. We analyse interventions from Botswana and Swaziland and highlight that for benefits to be long-lived and lead to sustainable land management, requires community engagement in project design, implementation and for project outputs to be used in developing community-led environmental monitoring tools that can then help to guide local decision-making systems. We stress the vital importance of continued participatory engagement of researchers with community leaders and key government staff beyond the timeframe of their initial research such that longitudinal research approaches can realise significant benefits to all concerned. In dynamic (non-equilibrium) dryland environments, it is vitally important that research approaches address temporal and spatial variability by mapping patterns of change, using a range of participatory tools to enhance understandings of the causes of land degradation and the opportunities for shifts towards more sustainable land management. Decision-support tools, such as rangeland assessment guides produced for various Kalahari rangeland settings in Botswana (via a UNEP project and affiliated research), provide opportunities to support more sustainable land management. However, at present benefits are not being fully realised as project and research staff move on after projects end. Similarly, findings from mixed farming systems in Swaziland (assessing a JICA-funded project) show problems in maintaining new institutional structures to manage rangeland degradation, whilst issues on arable areas associated with parasitic weeds (Striga asiatica) remain problematic. Findings from longitudinal research in Swaziland also show that community understandings of environmental problems have evolved over 10 years and identify new problems associated with intensified

    2011-02-01

    Full Text Available The use of the internet technology and web browser capabilities of the internethas provided researchers/scientists with many advantages, which includes butnot limited to ease of access, platform independence of computer systems,relatively low cost of web access etc. Hence online collaboration like socialnetworks and information/data exchange among individuals and organizationscan now be done seamlessly. In practice, many investigators rely heavily ondifferent data modalities for studying and analyzing their research/study and alsofor producing quality reports. The lack of coherency and inconsistencies in datasets can dramatically reduce the quality of research data. Thus to prevent loss ofdata quality and value and provide the needed functionality of data, we haveproposed a novel approach as an ad-hoc component for data monitoring andmanipulation called RTWebDMM (Real-Time Web-based Data Monitoring andManipulation system to improve the quality of translational research data. TheRTWebDMM is proposed as an auditor, monitor, and explorer for improving theway in which investigators access and interact with the data sets in real-timeusing a web browser. The performance of the proposed approach was evaluatedwith different data sets from various studies. It is demonstrated that the approachyields very promising results for data quality improvement while leveraging on aweb-enabled environment.

    2006-01-01

    Based on the internet technology, it has become possible to complete remote monitoring and fault diagnosis for the numerical control machine. In order to capture the micro-shock signal induced by the incipient fault on the rotating parts, the resonance demodulation technology is utilized in the system. As a subsystem of the remote monitoring system, the embedded data acquisition instrument not only integrates the demodulation board but also complete the collection and preprocess of monitoring data from different machines. Furthermore, through connecting to the internet, the data can be transferred to the remote diagnosis center and data reading and writing function can be finished in the database. At the same time, the problem of the IP address floating in the dial-up of web server is solved by the dynamic DNS technology. Finally, the remote diagnosis software developed on the LabVIEW platform can analyze the monitoring data from manufacturing field. The research results have indicated that the equipment status can be monitored by the system effectively.

  5. Radiation-related monitoring and environmental research at the Nevada Test Site

    Beginning with the first nuclear-weapons-related tests at the Nevada Test Site (NTS) in 1951, a radiation-related monitoring program was established to determine the levels and distribution of radionuclides released. Primary methods involved survey-meter-equipped field-monitoring teams and placement of film badges and air-sampling devices at fixed locations. Beginning in the mid-1950s, more stringent standards, the results of this monitoring program, and the results of related research programs led to increased engineering efforts to reduce local fallout. With passage of the National Environmental Policy Act and increased concern about possible effects of radiation exposure, environmental activities related to the NTS increased. There is now an extensive monitoring program at the NTS to assess radiological conditions resulting from past tests and from continued testing of nuclear-weapons devices. In populated areas near NTS, there is also a monitoring effort that relies on assistance from local communities. Other efforts include reconstruction of radiation doses received by offsite residents during the 1950s and 1960s, determination of the current inventory and distribution of radionuclides in surface soil, and studies of the movement of radionuclides in the desert ecosystem

  14. A novel performance monitoring framework for health research systems: experiences of the National Institute for Health Research in England

    Hallsworth Michael

    2011-03-01

    Full Text Available Abstract Background The National Institute for Health Research (NIHR was established in 2006 with the aim of creating an applied health research system embedded within the English National Health Service (NHS. NIHR sought to implement an approach for monitoring its performance that effectively linked early indicators of performance with longer-term research impacts. We attempted to develop and apply a conceptual framework for defining appropriate key performance indicators for NIHR. Method Following a review of relevant literature, a conceptual framework for defining performance indicators for NIHR was developed, based on a hybridisation of the logic model and balanced scorecard approaches. This framework was validated through interviews with key NIHR stakeholders and a pilot in one division of NIHR, before being refined and applied more widely. Indicators were then selected and aggregated to create a basket of indicators aligned to NIHR's strategic goals, which could be reported to NIHR's leadership team on a quarterly basis via an oversight dashboard. Results Senior health research system managers and practitioners endorsed the conceptual framework developed and reported satisfaction with the breadth and balance of indicators selected for reporting. Conclusions The use of the hybrid conceptual framework provides a pragmatic approach to defining performance indicators that are aligned to the strategic aims of a health research system. The particular strength of this framework is its capacity to provide an empirical link, over time, between upstream activities of a health research system and its long-term strategic objectives.

  15. Strategies for incorporation monitoring at PET-Centres: the Research Center Juelich GmbH

    The long-time research instrument positron emission tomography (PET) gains more and more importance in diagnostic and clinical applications. PET uses short lived positron emitters (e.g. 11C, 13N, 15O and 18F) as radioactive tracers. Development, production, transport and application of PET specific radiopharmaca involve a manifold of incorporation risks for the staff involved. Incorporation monitoring in Germany is generally regulated by a federal guideline. The procedures used at the research centre Juelich GmbH are taken as a basis to review the general strategies of incorporation monitoring a PET centres from production to application. Enhancements are proposed for inclusion in future editions of the guideline. (orig.)

    Health monitoring is a crucial aspect of the management of any research animal house. RESAMA is a network strong of 60 academic and private partners acting in France since the end of 2012. The network aims to increase awareness of animal caretakers and researchers on health management issues in facilities holding aquatic model species (zebrafish, Xenopus, medaka, Mexican tetra). To do so, each partner research facility will be visited at least once. The visiting team is composed at least of one veterinarian and one zootechnician specialized in aquatic species. The visit results in a health-monitoring assessment of the facility, which includes a sampling for histo-pathological, bacteriological, and molecular pathogen detection. During the visit, rearing practices are also reviewed through an interview of animal caretakers. However, the present report essentially focuses on the health-monitoring aspect. The ultimate goal of the project is to provide a network-wide picture of health issues in aquatic facilities. Performed in parallel, the rearing practice assessment will ultimately help to establish rational relationship between handling practices and animal health in aquatic facilities. The study is still in progress. Here, we describe the results to be drawn from an analysis of the 23 facilities that had been visited so far. We sampled 720 fish and 127 amphibians and performed a little less than 1400 individual tests. PMID:27192449

    2008-02-05

    The purpose ofthis document is to describe research, monitoring, and evaluation (RME) for the Federal Columbia River Estuary Program. The intent of this RME effort is to provide data and information to evaluate progress toward meeting program goals and objectives and support decision-making in the Estuary Program. The goal of the Estuary Program is to understand, conserve, and restore the estuary ecosystem to improve the performance of listed salmonid populations. The Estuary Program has five general objectives, designed to fulfill the program goal, as follows. 1. Understand the primary stressors affecting ecosystem controlling factors, such as ocean conditions and invasive species. 2. Conserve and restore factors controlling ecosystem structures and processes, such as hydrodynamics and water quality. 3. Increase the quantity and quality of ecosystem structures, i.e., habitats, juvenile salmonids use during migration through the estuary. 4. Maintain the food web to benefit salmonid performance. 5. Improve salmonid performance in terms of life history diversity, foraging success, growth, and survival. The goal of estuary RME is to provide pertinent and timely research and monitoring information to planners, implementers, and managers of the Estuary Program. In conclusion, the estuary RME effort is designed to meet the research and monitoring needs of the estuary Program using an adaptive management process. Estuary RME's success and usefulness will depend on the actual conduct of adaptive management, as embodied in the objectives, implrementation, data, reporting, and synthesis, evaluation, and decision-making described herein.

  20. The Carlsbad Environmental Monitoring and Research Center: An independent program for community information

    The Waste Isolation Pilot Plant (WIPP) was designed and built as a research and development facility to obtain data to demonstrate the safe management, storage, and disposal of defense-related transuranic (TRU) waste. The WIPP facility, near Carlsbad, New Mexico, is scheduled to receive its first shipment of TRU waste in 1992. The citizens of Carlsbad requested the U.S. Department of Energy (DOE) to provide them with an independent organization that would monitor the entire area with state-of-the-art monitoring techniques and publish the data. As a follow-up, the DOE approved a proposal from the Waste-management Education and Research Consortium of New Mexico to develop and implement this program. The purpose of this paper is to (1) describe this innovative program to establish the Carlsbad Environmental Monitoring and Research Center, an independent university based center to study health and environmental impacts associated with technological development; (2) present the Center's mission and objectives; and (3) give an overview of the progress.

  5. The importance of on-line monitoring systems within the environmental monitoring program of the Karlsruhe Nuclear Research Center

    The two on-line monitoring systems used in KfK environmental monitoring should be taken as measures of accident precaution and they are restricted to measurement of gamma local dose rates and of the (β + γ)-radiation levels. One of the systems serves to monitor the KfK operational area, the second serves to monitor the surrounding communities up to a radius of 8 km. By use of two different types of detectors the first system covers a range of measurement of 10 μrem/h to 1000 rem/h. By the second system only increases in the radiation level can be detected. It allows to record accidents in which countermeasures must be taken very urgently. The two monitoring systems are described which have been operated and partly been developed at the KfK. The possibilities and limits of using them for environmental monitoring are discussed. (orig./HP)

    Highlights: • Core power distribution of ex-core measurement system has been reconstructed. • Building up an artificial intelligence model for 3-D core power distribution. • Error of the experiments has been reduced to 0.76%. • Methods for improving the accuracy of the model have been obtained. - Abstract: A real-time monitor for 3D reactor power distribution is critical for nuclear safety and high efficiency of NPP’s operation as well as for optimizing the control system, especially when the nuclear power plant (NPP) works at a certain power level or it works in load following operation. This paper was based on analyzing the monitor for 3D reactor power distribution technologies used in modern NPPs. Furthermore, considering the latest research outcomes, the paper proposed a method based on using an ex-core neutron detector system and a neural network to set up a real time monitor system for reactor’s 3D power distribution supervision. The results of the experiments performed on a reactor simulation machine illustrated that the new monitor system worked very well for a certain burn-up range during the fuel cycle. In addition, this new model could reduce the errors associated with the fitting of the distribution effectively, and several optimization methods were also obtained to improve the accuracy of the simulation model

  7. Practical aspects of personal exposure monitoring in hospitals and research laboratories

    The practical aspects of personal exposure monitoring in hospitals and research laboratories are closely linked to the type of radiation source and methods used for diagnosis or therapy. Various sources emit X-rays, γ-photons, high energy electrons or beta particles. In external radiation therapy, sources are either sealed or electrically generated; in brachytherapy, they are sealed to be used in interstitial and intracavitary irradiation. A radiodiagnostic department applies X-rays in a variety of ways. In nuclear medicine and in research laboratories unsealed sources are to be used for intravenous injection and radioactive labelling. The personnal is thus exposed, to the risk of external exposure or both external and internal exposure. Additional survey procedures are needed in the following instances: 1) radiodiagnosis especially in the disciplines where X-rays are necessary for the follow-up of the intervention (orthopedics, vascular and interventional radiology); 2) brachytherapy where the handling of sources requires the monitoring of radiation exposure to the hands; 3) nuclear medicine where employees handling unsealed sources require additional survey of the hands as well. However, the highest risk is that of internal exposure following contamination. For this situation the legislation calls for a periodic radiotoxicological and/or whole-body counting. In practice, such monitoring carried out every 6 months is not always adapted to the circumstances

  8. Monitoring hydrogeological conditions in fractured rock at the site of Canada's underground research laboratory

    Atomic Energy of Canada Limited is constructing an Underground Research Laboratory (URL) at a depth of 250 m in a plutonic rock body near Lac du Bonnet, Manitoba. The facility is being constructed to carry out a variety of in situ geotechnical experiments as part of the Canadian Nuclear Fuel Waste Management Program. A unique feature of the URL, in comparison to other similar facilities such as the Stripa Mine in Sweden, is that it is to be constructed below the groundwater table in a previously undisturbed plutonic rock body. One of the main research objectives of the project is to develop and validate comprehensive three-dimensional models of the hydrogeology of the rock mass encompassing the URL site. Measurements made in an array of boreholes extending to depths of 1000 m on the 4.8-km2 study area have established that the permeability distribution in three major extensive subhorizontal fracture zones controls the movement of groundwater within the rock mass. An automated, electronic, piezometric pressure-monitoring system has been designed to collect continuous measurements from 75 isolated hydrogeological monitoring positions within the rock mass. Piezometric data have been collected from this monitoring network to establish baseline conditions prior to any excavation into the rock mass. These data have also been used to determine the steady-state, three-dimensional, groundwater flow regimes that exist at the URL site under natural conditions

It enables geo-scientists to easily synchronise, share, compute and visualise the dynamic and most up-to-date research data, scripts and models in multi-stakeholder geo-monitoring programs. This DataLab is developed by the Research Data Services team of TU Delft Library and 3TU.Datacentrum together with coastal engineers of Delft University of Technology and Deltares. Based on the OpenEarth software stack an environment has been developed to orchestrate numerous geo-related open source software components that can empower researchers and increase the overall research quality by managing research data; enabling automatic and interoperable data workflows between all the components with track & trace, hit & run data transformation processing in cloud infrastructure using MatLab and Python, synchronisation of data and scripts (SVN), and much more. Transformed interoperable data products (KML, NetCDF, PostGIS) can be used by ready-made OpenEarth tools for further analyses and visualisation, and can be distributed via interoperable channels such as THREDDS (OpenDAP) and GeoServer. An example of a successful application of OpenEarth DataLab is the Sand Motor, an innovative method for coastal protection in the Netherlands. The Sand Motor is a huge volume of sand that has been applied along the coast to be spread naturally by wind, waves and currents. Different research disciplines are involved concerned with: weather, waves and currents, sand distribution, water table and water quality, flora and fauna, recreation and management. Researchers share and transform their data in the OpenEarth DataLab, that makes it possible to combine their data and to see influence of different aspects of the coastal protection on their models.

    Full Text Available Jun Wu1, Wei He2, Wei-min Chen1, Lian Zhu21Key Laboratory of Optoelectronic Technology and Systems, 2State Key Laboratory of Power Transmission Equipment and System Security and New Technology, Chongqing University, Chongqing, People’s Republic of ChinaAbstract: The real-time monitoring of intracranial pressure (ICP is very important for craniocerebrally critically ill patients, but it is very difficult to realize long-time monitoring for the traditional invasive method, which very easily infects patients. Many noninvasive methods have emerged, but these have not been able to monitor ICP for long periods in real time, and they are not ready for clinical application. In order to realize long-time, online, real-time, noninvasive monitoring for ICP, a new method based on acoustoelasticity of ultrasound is herein proposed. Experimental models were devised to research the new method for experiment and simulation. Polymethyl methacrylate and hydrogel were adopted for the experiment, and their mechanical properties were very close to the real brain. A numerical solution for acoustoelasticity theory was acquired by simulating calculation based on a finite-element method. This was compared to the experimental value. The results showed a consistent match between theoretical solution and experimental value, with maximum error at most 5%. Thus, the effectiveness of the new method was verified. Theoretical and practical foundation is provided for this new method, and it could be used for animal experimentation or clinical testing in further research.Keywords: medical instruments, noninvasive, intracranial pressure, ultrasonic, acoustoelasticity, biomechanics

    The primary purpose of the safety parameter monitoring system (SPDS) is to help operating personnel in the control room make quick assessments of the plant safety status. Thus, the basic function of the SPDS is a provision of a continuous indication of plant parameters or derived variables representative of the safety status of the plant. NUREG-0737 Supplement 1 provides details of the functional criteria for the SPDS, as one of the action plan requirements from TMI accident. The system provides various functions as follows: · Alerting based on safety function decision logics, · Success path analysis to achieve the integrity of the safety functions, · 3 layer display architecture - safety function, success path display for each safety function, system summary and equipment details for each safety function, · Integration with computer-based procedure. According to a Notice of the NSSC No. 2012-31, a research reactor facility generating more than 2 MW of power should also be furnished with the SPDS for emergency preparedness. Generally, a research reactor is a small size facility, and its number of instrumentations is fewer than that of NPPs. In particular, it is actually hard to have various and powerful functions from an economic perspective. Therefore, a safety parameter display system optimized for a research reactor facility must be proposed. This paper provides the requirement analysis results and proposes the design of safety parameter monitoring function for a research reactor. The safety parameter monitoring function supporting control room personnel during emergency conditions should be designed in a research reactor facility. The facility size and number of signals are smaller than that of the power plants. Also, it is actually hard to have various and powerful functions of nuclear power plants from an economic perspective. Thus, a safety parameter display system optimized to a research reactor must be proposed. First, we found important design items

    Most research to assess amphibian declines has focused on local-scale projects on one or a few species. The Amphibian Research and Monitoring Initiative (ARMI) is a national program in the United States mandated by congressional directive and implemented by the U.S. Department of the Interior (specifically the U.S. Geological Survey, USGS). Program goals are to monitor changes in populations of amphibians across U.S. Department of the Interior lands and to address research questions related to amphibian declines using a hierarchical framework of base-, mid- and apex-level monitoring sites. ARMI is currently monitoring 83 amphibian species (29% of species in the U.S.) at mid- and apex-level areas. We chart the progress of this 5-year-old program and provide an example of mid-level monitoring from 1 of the 7 ARMI regions.

    2010-01-01

    In order to optimize monitoring points and monitoring factor, the relationship between pollutants and soil sample were established by correspondence analysis. The study results show that the reflecting monitoring points and monitoring factors in the graphic on the same factor axis can clearly express the intrinsic link between pollutants and monitoring points and distribution characteristics. To determine the main monitoring point and the main monitoring indicators can reduce and optimize the number of monitoring points under the premise of ensuring the typical and representative of monitoring data.Using the correlation of pollutants can reduce the number of monitoring indicators and improve the effectiveness of data collection.

    Neutron monitors (NMs) are ground-based devices to measure the variation of cosmic ray intensities, and although being reliable they have two disadvantages: their size as well as their weight. As consequence, [1] suggested the development of a portable, and thus much smaller and lighter, calibration neutron monitor that can be carried to any existing station around the world [see 2; 3]. But this mini neutron monitor, moreover, can also be installed as an autonomous station at any location that provides ’’office” conditions such as a) temperatures within the range of around 0 to less than 40 degree C as well as b) internet and c) power supply. However, the best location is when the material above the NM is minimized. In 2011 a mini Neutron Monitor was installed at the Neumayer III station in Antarctica as well as the German research vessel Polarstern, providing scientific data since January 2014 and October 2012, respectively. The Polarstern, which is in the possession of the Federal Republic of Germany represented by the Ministry of Education and Research and operated by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research and managed by the shipping company Laeisz, was specially designed for working in the polar seas and is currently one of the most sophisticated polar research vessels worldwide. It spends almost 310 days a year at sea usually being located in the waters of Antarctica between November and March while spending the northern summer months in Arctic waters. Therefore, the vessel scans the rigidity range below the atmospheric threshold and above 10 GV twice a year. In contrast to spacecraft measurements NM data are influenced by variations of the geomagnetic field as well as the atmospheric conditions. Thus, in order to interpret the data a detailed knowledge of the instrument sensitivity with geomagnetic latitude (rigidity) and atmospheric pressure is essential. In order to determine the atmospheric response data from the

    The recently (2013) identified pathogenic chytrid fungus, Batrachochytrium salamandrivorans (Bsal), poses a severe threat to the distribution and abundance of salamanders within the United States and Europe. Development of a response strategy for the potential, and likely, invasion of Bsal into the United States is crucial to protect global salamander biodiversity. A formal working group, led by Amphibian Research and Monitoring Initiative (ARMI) scientists from the U.S. Geological Survey (USGS) Patuxent Wildlife Research Center, Fort Collins Science Center, and Forest and Rangeland Ecosystem Science Center, was held at the USGS Powell Center for Analysis and Synthesis in Fort Collins, Colorado, United States from June 23 to June 25, 2015, to identify crucial Bsal research and monitoring needs that could inform conservation and management strategies for salamanders in the United States. Key findings of the workshop included the following: (1) the introduction of Bsal into the United States is highly probable, if not inevitable, thus requiring development of immediate short-term and long-term intervention strategies to prevent Bsal establishment and biodiversity decline; (2) management actions targeted towards pathogen containment may be ineffective in reducing the long-term spread of Bsal throughout the United States; and (3) early detection of Bsal through surveillance at key amphibian import locations, among high-risk wild populations, and through analysis of archived samples is necessary for developing management responses. Top research priorities during the preinvasion stage included the following: (1) deployment of qualified diagnostic methods for Bsal and establishment of standardized laboratory practices, (2) assessment of susceptibility for amphibian hosts (including anurans), and (3) development and evaluation of short- and long-term pathogen intervention and management strategies. Several outcomes were achieved during the workshop, including development

    2014-01-01

    As one of the dynamic disasters of coal mines, rockburst seriously affects underground safe coal mining. Based on the laboratory test, field test, and theoretical analysis, this study proposed the principle of the rock burst induced by the combination of dynamic and static stresses and divided such rock burst into three types, including induced by primary dynamic stress, mainly induced by dynamic stress, and by dynamic stress in low critical stress state. The expressions of the static stress induced by coal mining and dynamic stress induced by mining tremors were obtained. Moreover, theories and technologies at home and abroad were summarized concerning the monitoring, forecasting, and preventing of rockburst. These mainly include the zoning and leveling forecasting method, electromagnetic radiation technology, elastic wave and seismic wave computed tomography technologies in aspect of rockburst monitoring, as well as the intensity weakening theory, the strong-soft-strong structure effect, the directional hydraulic fracturing technology, the roadway support system in regards of rockburst prevention. The prospect of rockburst development suggested that researches concerning the rockburst mechanism should be quantitatively developed around the roadway and coalface surrounding coal-rock mass. It should be focused on the rockburst mechanism and prevention technology of mining with over 1,000 km deep and mining in large tectonic zone. In addition, the monitoring and prevention of rockburst should be based on rockburst mechanism.

    2002-01-01

    Development and evaluation of Intensive Care Unit (ICU) decision-support systems would be greatly facilitated by the availability of a large-scale ICU patient database. Following our previous efforts with the MIMIC (Multi-parameter Intelligent Monitoring for Intensive Care) Database, we have leveraged advances in networking and storage technologies to develop a far more massive temporal database, MIMIC II. MIMIC II is an ongoing effort: data is continuously and prospectively archived from all ICU patients in our hospital. MIMIC II now consists of over 800 ICU patient records including over 120 gigabytes of data and is growing. A customized archiving system was used to store continuously up to four waveforms and 30 different parameters from ICU patient monitors. An integrated user-friendly relational database was developed for browsing of patients' clinical information (lab results, fluid balance, medications, nurses' progress notes). Based upon its unprecedented size and scope, MIMIC II will prove to be an important resource for intelligent patient monitoring research, and will support efforts in medical data mining and knowledge-discovery.

  5. Comparison of the technical performance of the atmospheric radionuclide monitoring systems and their applications to science research

    Environmental radionuclide monitoring systems set up around a nuclear facility work for detecting radioactivities which might be released into the atmosphere by an accident of the nuclear facility. On the other hand, similar monitoring techniques are applied to an international monitoring network for CTBT (Comprehensive Nuclear-Test-Ban Treaty). The network is prepared for verification of compliance with this treaty, and for detecting a nuclear explosion. For this purpose, 80 atmospheric radionuclide monitoring stations will be set up all over the world, and among them two radionuclide stations will be established in Japan (Takasaki and Okinawa). An automatic monitoring system which is commercially available will be installed at each of Japanese stations. There are requirements to be met by the system such as the detection limit and the data availability, and these are severer than those for environmental monitoring systems in use. If the data obtained from the CTBT monitoring network are opened for use in research fields, they could be useful not only for the monitoring of radioactivities caused by a nuclear power accident but also in the fields of environmental sciences and earth sciences. In this report, performance of a CTBT monitoring system is compared with that of the environmental monitoring system in use, and applications of the CTBT monitoring data to the environmental and earth sciences are considered.

    Johnson, Gary E.; Diefenderfer, Heida L. (Pacific Northwest National Laboratory)

    2008-02-20

    The purpose of this document is to describe research, monitoring, and evaluation (RME) for the Federal Columbia River Estuary Program, hereafter called 'the Estuary Program'. The intent of this RME effort is to provide data and information to evaluate progress toward meeting program goals and objectives and support decision making in the Estuary Program. The goal of the Estuary Program is to understand, conserve, and restore the estuary ecosystem to improve the performance of listed salmonid populations. The Estuary Program has five general objectives, designed to fulfill the program goal, as follows: (1) Understand the primary stressors affecting ecosystem controlling factors, such as ocean conditions and invasive species. (2) Conserve and restore factors controlling ecosystem structures and processes, such as hydrodynamics and water quality. (3) Increase the quantity and quality of ecosystem structures, i.e., habitats, juvenile salmonids use during migration through the estuary. (4) Maintain the food web to benefit salmonid performance. (5) Improve salmonid performance in terms of life history diversity, foraging success, growth, and survival. The goal of estuary RME is to provide pertinent and timely research and monitoring information to planners, implementers, and managers of the Estuary Program. The goal leads to three primary management questions pertaining to the main focus of the Estuary Program: estuary habitat conservation and restoration. (1) Are the estuary habitat actions achieving the expected biological and environmental performance targets? (2) Are the offsite habitat actions in the estuary improving juvenile salmonid performance and which actions are most effective at addressing the limiting factors preventing achievement of habitat, fish, or wildlife performance objectives? (3) What are the limiting factors or threats in the estuary/ocean preventing the achievement of desired habitat or fish performance objectives? Performance measures

    Full Text Available Since 1987, the Regional Forestry Board of Lombardy and the Water Research Institute of the National Research Council have been carrying out surveys of forest conditions and the response of the ecosystem to environmental factors. The study approach is based on a large number of permanent plots for extensive monitoring (Level 1. At this level, crown condition is assessed annually, and soil condition and the nutritional status of forests surveyed. Some of the permanent plots were selected for intensive monitoring (Level 2, focussing mainly on the impact of atmospheric pollution on forest ecosystems. Level 2 monitoring also includes increment analyses, ground vegetation assessment, atmospheric deposition, soil solution analyses and climatic observations. This paper summarises the main results of a pluriannual research, which provides a general picture of the state of forest health in the region and focuses on more detailed investigations, described as case studies. Modified wet and dry samplers which use a water surface to collect dry deposition were used in a pluriannual field campaign at five sites in alpine and prealpine areas, to measure the total atmospheric depositions and to evaluate the nitrogen and sulphate exceedances of critical loads. Throughfall and bulk precipitation chemistry were studied for five years (June 1994-May 1999 at two high elevation forest sites (Val Gerola and Val Masino which were known to differ in terms of tree health, as assessed by live crown condition. Results indicated a higher contribution from the dry deposition of N-NO3 -, N-NH4 + and H+ and considerable canopy leaching of Ca2+, K+ and weak organic acids at Val Gerola, where the symptoms of damage were more evident. In the area of Val Masino (SO, included since 1997 in the national CONECOFOR network, investigations focused on the effectiveness of the biological compartment in modifying fluxes of atmospheric elements, and on the role of nitrogen both as an

    WEGENER was originally the acronym for Working Group of European Geoscientists for the Establishment of Networks for Earth-science Research. It was founded in March 1981 in response to an appeal delivered at the Journées Luxembourgeoises de Geodynamique in December 1980 to respond with a coordinated European proposal to a NASA Announcement of Opportunity inviting participation in the Crustal Dynamics and Earthquake Research Program. WEGENER, during the past 33 years, has always kept a close contact with the Agencies and Institutions responsible for the development and maintenance of the global space geodetic networks with the aim to make them aware of the scientific needs and outcomes of the project which might have an influence on the general science policy trends. WEGENER served as Inter-commission Project 3.2, between Commission 1 and Commission 3, of the International Association of Geodesy (IAG) until 2012. Since then, WEGENER project has become the Sub-commission 3.5 of IAG commission 3, namely Tectonics and Earthquake Geodesy. In this presentation, we briefly review the accomplishments of WEGENER as originally conceived and outline and justify the new focus of the WEGENER consortium. The remarkable and rapid evolution of the present state of global geodetic monitoring in regard to the precision of positioning capabilities (and hence deformation) and global coverage, the development of InSAR for monitoring strain with unprecedented spatial resolution, and continuing and planned data from highly precise satellite gravity and altimetry missions, encourage us to shift principal attention from mainly monitoring capabilities by a combination of space and terrestrial geodetic techniques to applying existing observational methodologies to the critical geophysical phenomena that threaten our planet and society. Our new focus includes developing an improved physical basis to mitigate earthquake, tsunami, and volcanic risks, and the effects of natural and

  13. Monitoring cognitive function and need with the automated neuropsychological assessment metrics in Decompression Sickness (DCS) research

    1993-01-01

    Hypobaric decompression sickness (DCS) research presents the medical monitor with the difficult task of assessing the onset and progression of DCS largely on the basis of subjective symptoms. Even with the introduction of precordial Doppler ultrasound techniques for the detection of venous gas emboli (VGE), correct prediction of DCS can be made only about 65 percent of the time according to data from the Armstrong Laboratory's (AL's) hypobaric DCS database. An AL research protocol concerned with exercise and its effects on denitrogenation efficiency includes implementation of a performance assessment test battery to evaluate cognitive functioning during a 4-h simulated 30,000 ft (9144 m) exposure. Information gained from such a test battery may assist the medical monitor in identifying early signs of DCS and subtle neurologic dysfunction related to cases of asymptomatic, but advanced, DCS. This presentation concerns the selection and integration of a test battery and the timely graphic display of subject test results for the principal investigator and medical monitor. A subset of the Automated Neuropsychological Assessment Metrics (ANAM) developed through the Office of Military Performance Assessment Technology (OMPAT) was selected. The ANAM software provides a library of simple tests designed for precise measurement of processing efficiency in a variety of cognitive domains. For our application and time constraints, two tests requiring high levels of cognitive processing and memory were chosen along with one test requiring fine psychomotor performance. Accuracy, speed, and processing throughout variables as well as RMS error were collected. An automated mood survey provided 'state' information on six scales including anger, happiness, fear, depression, activity, and fatigue. An integrated and interactive LOTUS 1-2-3 macro was developed to import and display past and present task performance and mood-change information.

    Ocean monitoring and forecasting services are increasingly being used by a diverse community of public and commercial organizations. The Met Office, as the body responsible for severe weather prediction, has for many years been involved in providing forecasts of aspects of the marine environment. This paper describes how these have evolved to include a range of wave, surge, and ocean reanalysis, analysis, and forecasts services. To support these services, and to ensure they evolve to meet the demands of users and are based on the best available science, a number of scientific challenges need to be addressed. The paper goes on to summarize the key challenges, and highlights some priorities for the ocean monitoring and forecasting research group at the Met Office. There is a need to both develop the underpinning science of the modelling and data assimilation systems and to maximize the benefits from observations and other inputs to the systems. Systematic evaluation underpins this science, and also needs to be the focus of research.

    2013-04-01

    Ambient Intelligence (AmI) provides extended but unobtrusive sensing and computing devices and ubiquitous networking for human/environment interaction. It is a new paradigm in information technology compliant with the international Integrating Healthcare Enterprise board (IHE) and eHealth HL7 technological standards in the functional integration of biomedical domotics and informatics in hospital and home care. AmI allows real-time automatic recording of biological/medical information and environmental data. It is extensively applicable to patient monitoring, medicine and neuroscience research, which require large biomedical data sets; for example, in the study of spontaneous or condition-dependent variability or chronobiology. In this respect, AML is equivalent to a traditional laboratory for data collection and processing, with minimal dedicated equipment, staff, and costs; it benefits from the integration of artificial intelligence technology with traditional/innovative sensors to monitor clinical or functional parameters. A prototype AmI platform (MIMERICA*) has been implemented and is operated in a semi-intensive unit for the vegetative and minimally conscious states, to investigate the spontaneous or environment-related fluctuations of physiological parameters in these conditions.

  19. Environmental assessment of the Carlsbad Environmental Monitoring and Research Center Facility

    NONE

    1995-10-01

    This Environmental Assessment has been prepared to determine if the Carlsbad Environmental Monitoring and Research Center (the Center), or its alternatives would have significant environmental impacts that must be analyzed in an Environmental Impact Statement. DOE`s proposed action is to continue funding the Center. While DOE is not funding construction of the planned Center facility, operation of that facility is dependent upon continued funding. To implement the proposed action, the Center would initially construct a facility of approximately 2,300 square meters (25,000 square feet). The Phase 1 laboratory facilities and parking lot will occupy approximately 1.2 hectares (3 acres) of approximately 8.9 hectares (22 acres) of land which were donated to New Mexico State University (NMSU) for this purpose. The facility would contain laboratories to analyze chemical and radioactive materials typical of potential contaminants that could occur in the environment in the vicinity of the DOE Waste Isolation Pilot Plant (WIPP) site or other locations. The facility also would have bioassay facilities to measure radionuclide levels in the general population and in employees of the WIPP. Operation of the Center would meet the DOE requirement for independent monitoring and assessment of environmental impacts associated with the planned disposal of transuranic waste at the WIPP.

  3. Incorporation of personal computers in a research reactor instrumentation system for data monitoring and analysis

    The research contract was implemented by obtaining off-the shelf personal computer hardware and data acquisition cards, designing the interconnection with the instrumentation system, writing and debugging the software, and the assembling and testing the set-up. The hardware was designed to allow all variables monitored by the instrumentation system to be accessible to the computers, without requiring any major modification of the instrumentation system and without compromising reactor safety in any way. The computer hardware addition was also designed to have no effect on any existing function of the instrumentation system. The software was designed to implement only graphical display and automated logging of reactor variables. Additional functionality could be easily added in the future with software revision because all the reactor variables are already available in the computer. It would even be possible to ''close the loop'' and control the reactor through software. It was found that most of the effort in an undertaking of this sort will be in software development, but the job can be done even by non-computer specialized reactor people working with programming languages they are already familiar with. It was also found that the continuing rapid advance of personal computer technology makes it essential that such a project be undertaken with inevitability of future hardware upgrading in mind. The hardware techniques and the software developed may find applicability in other research reactors, especially those with a generic analog research reactor TRIGA console. (author)

  5. Research for the life-extension of the wide-range monitoring neutron detectors of HTTR (Joint research)

    The Wide-Range Monitoring neutron detectors (WRM detectors) of HTTR are used under the high temperature environment of 450degC in normal operation and 550degC in the accidents. When the WRM detectors are used under the high temperature environment for a long time, characteristics of the neutron detector might be degraded, because of the decrease of the nitrogen concentration in the ionization gas caused by adsorption of nitrogen into the electrode material. Consequently, the nitrogen gas adsorption test was carried out to clarify the quantity of absorbed nitrogen gas in electrode material under the high temperature environment. Then, the performance evaluation test of the prototype detector was carried out, and it was confirmed that degradation of the prototype detector characteristics, caused by adsorption of nitrogen into the electrode material, didn't occur under the high temperature environment. As a result of this research, it was confirmed that the WRM detectors of HTTR are usable for 5 years under the high temperature environment of 450degC in normal operation. This report describes the results of consideration about the life-extension of WRM detectors of HTTR. (author)

The environmental assessment component is a coordinated programme involving groups and institutions in 16 countries. The longterm objectives are stated and the activities undertaken are given. Four types of monitoring are being carried out - of sources, of coastal areas, of reference areas and of the transport of pollutants to the Mediterranean Sea through the atmosphere. The research activities are outlined and the resulting reports are considered. The state of pollution is assessed and the measures proposed to solve the problems are given. In particular, mercury pollution is explained. (UK)

  9. Development of a neural network to monitor the nuclear power IEA-R1 research reactor

    After the Three Mile Island accident, engineers and researches from the control and instrument area, started to analyze the practicability and functionality of conventional control rooms. The conclusion was that a great amount of information was available, but without any priority, so the responsibility of coordination and selection of actions was based on the experience or the reactor supervisor, and as shown in the case of Three Mile, sometimes it was not enough to avoid undesired consequences to the installation. According to these results, several tools and techniques of data processing were developed to priorize information in order to give the operators an easier way to identify failures and consequent actions to minimize its effects. The use of Neural Networks is one of these techniques, with a great potential of development to help the operator to identify plant situations. This work evaluates two proposed types of Neural Networks to monitor the nuclear power of IEA-R1 research reactor. One network is the so called Multi Layer Perceptron (MLP), and the other is the Radial Basis Function (RBF). The objective is to create a diversional from the present the information about the reactor power to the operator, in order to help him to identify possible failures in the instrumentation and control system of the reactor. It will be shown the performance of each network, and a comparison between them, with the conclusion that the RBF Neural Network presents a better performance for the proposed application. (author)

  10. Research on no-contact remote monitoring technology for nuclear power structural members

    As the main cause of radioactivation in nuclear power plants which is considered to be the factor of occupational radiation exposure, there are the phenomena of the falling-off of fine metal particles from the surfaces of structural members by cavitation erosion, radioactivation, and adhesion to member surfaces. If the surfaces of members are rough, these phenomena are remarkably promoted. The smoothing and the evaluation of soundness of the inner surfaces of tubular members have become important subjects. In this research, for the purpose of accurately measuring and evaluating the factors affecting the reliability and safety of small diameter tubes such as flaws and cracks when their inner surfaces are smoothed, the researches on optical no-contact monitoring technology and the technology of evaluating material surface have been carried out. In this fiscal year, the defect detection sensor using oblique incidence optical system and the multi-nozzle type pneumatic holding mechanism for in-tube measuring system were made for trial. The electrolytic polishing experiment using SUS 316 stainless steel samples was carried out. Reports are made on these studies. (K.I.)

  14. Gas Bubble Disease Monitoring and Research of Juvenile Salmonids : Annual Report 1996.

    Maule, Alec G.; Beeman, John W.; Hans, Karen M.; Mesa, M.G.; Haner, P.; Warren, J.J. [Geological Survey, Cook, WA (United States). Columbia River Research Lab.

    1997-10-01

    This document describes the project activities 1996--1997 contract year. This report is composed of three chapters which contain data and analyses of the three main elements of the project: field research to determine the vertical distribution of migrating juvenile salmonids, monitoring of juvenile migrants at dams on the Snake and Columbia rivers, and laboratory experiments to describe the progression of gas bubble disease signs leading to mortality. The major findings described in this report are: A miniature pressure-sensitive radio transmitter was found to be accurate and precise and, after compensation for water temperature, can be used to determine the depth of tagged-fish to within 0.32 m of the true depth (Chapter 1). Preliminary data from very few fish suggest that depth protects migrating juvenile steelhead from total dissolved gas supersaturation (Chapter 1). As in 1995, few fish had any signs of gas bubble disease, but it appeared that prevalence and severity increased as fish migrated downstream and in response to changing gas supersaturation (Chapter 2). It appeared to gas bubble disease was not a threat to migrating juvenile salmonids when total dissolved gas supersaturation was < 120% (Chapter 2). Laboratory studies suggest that external examinations are appropriate for determining the severity of gas bubble disease in juvenile salmonids (Chapter 3). The authors developed a new method for examining gill arches for intravascular bubbles by clamping the ventral aorta to reduce bleeding when arches were removed (Chapter 3). Despite an outbreak of bacterial kidney disease in the experimental fish, the data indicate that gas bubble disease is a progressive trauma that can be monitored (Chapter 3).

  15. Development of a fuel failure monitoring method for a pool-type research reactor

    Studies on developing a sensitive monitoring method of possible release of fission products (FP) from a fuel element have been made for a pool-type research reactor. It consists of introducing gas bubbles into reactor coolant water to extract effectively the dissolved fission rare gases, 89Kr and 138Xe, produced somewhere in the core, and counting their respective daughter nuclides, 89Rb and 138Cs with high efficiency. The measurements were done by either method, (I) on a filter paper by sucking the bubbled gas and air covering water of the reactor tank, or (II) in the washing water of bubbled gas sampled into a bottle at the water surface. The followings are the summary of the results obtained. (1) DE increased as much as 30 times or more compared with no gas bubbling. (2) DE largely increased with increasing flow rate of introducing gas. (3) DE increased with increasing depth of the gas exit in the water. (4) DE at the same depth depended on the position of gas exit. It was larger for 'side' position than for 'center', due to the water convection in the tank. (5) DE largely depended on the condition of whether the primary cooling system was operated or not. (6) In Method II, DE depended on the time of standing, and it showed maximum at the theoretically predicted value. (7) The theoretical analysis for the effect of depth suggests that DE should be proportional to the value =(1+D /1033)2-(1+D /1033)5/3=, where D is the depth (in cm). The trend agreed at least partly with the observed data. (8) As a continuous mode experiment, we constructed an automatic fuel monitoring system for routine use by adopting Method II. It is composed of an intermittent sampling of the bubbling gas into bottle at the water surface, washing it with water after definite time of standing, and measuring the nuclides contained in the water.

    2001-01-01

    On the basis of analyzing the influencing factors and harmfulness of stray current, and discussing the existing problems of monitoring and prevention system for stray current, the integrated monitoring and prevention system for stray current in metro was developed. A net system of distributed computers for monitoring was set up. It can monitor the distribution of stray current in metro and the corrosion of the metal structure in the whole line. According to the situation of monitoring it can also control the drainage of its tank to reach the best effect and eliminate the negative effect of polarity drainage. By using the new type unilateral electric device, the problem of burning the rail by electric arc can be avoided. The unilateral electric device can be connected with the monitoring net system directly to realize the monitor in line and improve the reliability of the device.

The present report is based on work performed by Imre Pazsit, Victor Dykin, Anders Jonsson and Christophe Demaziere, with Imre Pazsit being the project leader. This report describes the results obtained during Stage 16 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. The long-term goals are elaborated in more detail in e.g. the Final Reports of Stage 1 and 2 (SKI Report 95:14 and 96:50, Pazsit et al. 1995, 1996). Results up to Stage 15 were reported in (Pazsit et al. 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2003a, 2003b; Demaziere et al, 2004; Sunde et al, 2006; Pazsit et al. 2008, 2009). A brief proposal for the continuation of this program in Stage 17 is also given at the end of the report. The program executed in Stage 16 consists of four parts as follows: - An overview of the present status of experience with BWR stability; - An investigation of the significance of the properties of the noise source for BWR instability; - Study of the dynamics of molten salt systems: construction of the adjoint and calculating the space dependent noise induced by propagating perturbations in the fuel; - A specific study of some novel methods of analysis of non-linear and non-stationary processes

  20. Beam loss monitor system of the rapid cycling synchrotron of Japan Proton Accelerator Research Complex

    The 3 GeV Rapid Cycling Synchrotron (RCS) of the Japan Proton Accelerator Research Complex (J-PARC) provides more than 300 kW beam to the Material and Life Science Facility (MLF) and the Main Ring (MR). In such high intensity hadron accelerator, the lost protons that are a fraction of the beam less than 0.1% cause many problems. Those particles bring about a serious radioactivation and a malfunction of the accelerator components. Therefore, the beam loss monitor (BLM) is one of the most important equipment to observe the state of the beam during operation, and to keep a steady operation. Moreover, if we set operation parameters of BLM adequately, it can detect the beam loss that is 10-6 fraction of the beam. Thus it enables fine-tuning of the accelerator. In the J-PARC RCS, a proportional counter and a plastic scintillation counter are used for the beam commission and the stable operation as BLM. We report present status of the BLM system in J-PARC RCS. (author)

  1. Remote Sensing and GIS for Habitat Quality Monitoring: New Approaches and Future Research

    András Zlinszky

    2015-06-01

    Full Text Available Habitat quality is the ability of the environment to provide conditions appropriate for individual and species persistence. Measuring or monitoring habitat quality requires complex integration of many properties of the ecosystem, where traditional terrestrial data collection methods have proven extremely time-demanding. Remote sensing has known potential to map various ecosystem properties, also allowing rigorous checking of accuracy and supporting standardized processing. Our Special Issue presents examples where remote sensing has been successfully used for habitat mapping, quantification of habitat quality parameters, or multi-parameter modelling of habitat quality itself. New frontiers such as bathymetric scanning, grassland vegetation classification and operational use were explored, various new ecological verification methods were introduced and integration with ongoing habitat conservation schemes was demonstrated. These studies show that remote sensing and Geoinformation Science for habitat quality analysis have evolved from isolated experimental studies to an active field of research with a dedicated community. It is expected that these new methods will substantially contribute to biodiversity conservation worldwide.

    Larson, G.L.; Collier, R.; Buktenica, M.

    2007-01-01

    Crater Lake is located in the caldera of Mount Mazama in Crater Lake National Park, Oregon. The lake has a surface area of about 53 km2at an elevation of 1882 m and a maximum depth of 594 m. Limited studies of this ultraoligotrophic lake conducted between 1896 and 1981, lead to a 10-year limnological study to evaluate any potential degradation of water quality. No long-term variations in water quality were observed that could be attributed to anthropogenic activity. Building on the success of this study, a permanent limnological program has been established with a long-term monitoring program to insure a reliable data base for use in the future. Of equal importance, this program serves as a research platform to develop and communicate to the public a better understanding of the coupled biological, physical, and geochemical processes in the lake and its surrounding environment. This special volume represents our current state of knowledge of the status of this pristine ecosystem including its special optical properties, algal nutrient limitations, pelagic bacteria, and models of the inter-relationships of thermal properties, nutrients, phytoplankton, deep-water mixing, and water budgets. ?? 2007 Springer Science+Business Media B.V.

  6. Australian regulatory licensing and compliance monitoring of the construction of a research reactor

    Full text: The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) was established by the Australian Radiation Protection and Nuclear Safety Act 1998 to perform a number of specific functions. Licensing and Compliance Monitoring of those activities involving radiation, that are undertaken by Commonwealth entities, are two of these functions. When making a decision on whether to issue a licence, the CEO of ARPANSA is obliged by the ARPANS Act to take into account a number of matters. The information that the CEO may request to assist make his decision includes (but is not limited to): (a) The design of the controlled facility, including ways in which the design deals with the physical and environmental characteristics of the site; (b) Any fundamental difficulties that will need to be resolved before any future authorisation is given; (c) The construction plan and schedule; (d) A preliminary safety analysis report that demonstrates the adequacy of the design of the facility and identifies structure, components and systems that are safety related items; (e) The arrangements for testing and commissioning safety related items. A licence granted by the CEO of ARPANSA is subject to a number of licence conditions. These licence conditions fall into three categorises: (1) Licence conditions prescribed by the Act and Regulations; (2) Licence conditions imposed by the CEO at the time of making the licence decision; (3) Licence conditions imposed by the CEO at a time after the licence has been granted. The regulatory compliance monitoring of these conditions during the construction of the ANSTO Replacement Research Reactor will be described. Two licence conditions of significance during the construction process are: (1) The holder of a licence must seek the CEO's prior approval to make a relevant change that will have significant implications for safety. (2) The holder of a licence, or person covered by a licence, must only construct an item that is important

    Sever, Thomas; Irwin, Daniel; Sader, Steven A.; Saatchi, Sassan

    2004-01-01

    To foster scientific cooperation under a Memorandum of Understanding between NASA and the Central American countries, the research project developed regional databases to monitor forest condition and environmental change throughout the region. Of particular interest is the Mesoamerican Biological Corridor (MBC), a chain of protected areas and proposed conservation areas that will link segments of natural habitats in Central America from the borders of northern Columbia to southern Mexico. The first and second year of the project focused on the development of regional satellite databases (JERS-IC, MODIS, and Landsat-TM), training of Central American cooperators and forest cover and change analysis. The three regional satellite mosaics were developed and distributed on CD-ROM to cooperators and regional outlets. Four regional remote sensing training courses were conducted in 3 countries including participants from all 7 Central American countries and Mexico. In year 3, regional forest change assessment in reference to Mesoamerican Biological Corridor was completed and land cover maps (from Landsat TM) were developed for 7 Landsat scenes and accuracy assessed. These maps are being used to support validation of MODIS forest/non forest maps and to examine forest fragmentation and forest cover change in selected study sites. A no-cost time extension (2003-2004) allowed the completion of an M.S. thesis by a Costa Rican student and preparation of manuscripts for future submission to peer-reviewed outlets. Proposals initiated at the end of the project have generated external funding from the U.S. Forest Service (to U. Maine), NASA-ESSF (Oregon State U.) and from USAID and EPA (to NASA-MSFC-GHCC) to test MODIS capabilities to detect forest change; conduct literature review on biomass estimation and carbon stocks and develop a regional remote sensing monitoring center in Central America. The success of the project has led to continued cooperation between NASA, other federal

  8. [The Research for Trace Ammonia Escape Monitoring System Based on Tunable Diode Laser Absorption Spectroscopy].

    Zhang, Li-fang; Wang, Fei; Yu, Li-bin; Yan, Jian-hua; Cen, Ke-fa

    2015-06-01

    In order to on-line measure the trace ammonia slip of the commercial power plant in the future, this research seeks to measure the trace ammonia by using tunable diode laser absorption spectroscopy under ambient temperature and pressure, and at different temperatures, and the measuring temperature is about 650 K in the power plant. In recent years lasers have become commercially available in the near-infrared where the transitions are much stronger, and ammonia's spectroscopy is pretty complicated and the overlapping lines are difficult to resolve. A group of ammonia transitions near 4 433.5 cm(-1) in the v2 +v3 combination band have been thoroughly selected for detecting lower concentration by analyzing its absorption characteristic and considering other absorption interference in combustion gases where H2O and CO2 mole fraction are very large. To illustrate the potential for NH3 concentration measurements, predictions for NH3, H2O and CO2 are simultaneously simulated, NH3 absorption lines near 4 433.5 cm(-1) wavelength meet weaker H2O absorption than the commercial NH3 lines, and there is almost no CO2 absorption, all the parameters are based on the HITRAN database, and an improved detection limit was obtained for interference-free NH3 monitoring, this 2.25 μm band has line strengths several times larger than absorption lines in the 1.53 μm band which was often used by NH3 sensors for emission monitoring and analyzing. The measurement system was developed with a new Herriott cell and a heated gas cell realizing fast absorption measurements of high resolution, and combined with direct absorption and wavelenguh modulation based on tunable diode laser absorption spectroscopy at different temperatures. The lorentzian line shape is dominant at ambient temperature and pressure, and the estimated detectivity is approximately 0.225 x 10(-6) (SNR = 1) for the directed absorption spectroscopy, assuming a noise-equivalent absorbance of 1 x 10(-4). The heated cell

  9. Japanese BWR utilities joint research on fatigue monitoring system of RPV

    Considering the plant life extension (PLEX) of nuclear power plants (NPPs) in the future, Japanese BWR electric utilities are carrying out the research project on the fatigue monitoring system based on the actual plant operating data. Reactor Pressure Vessel (RPV) is one of the most critical components of BWR when utilities think about PLEX. RPV is designed by the detail stress analysis using the method such as Finite Element Analysis (FEA). Design stress analysis is performed in accordance with design basis thermal cycles for design life of 40 years and it sometimes reports considerably high fatigue usage factors at such portions of RPV as stud bolt, feedwater nozzle and support skirt. However, because of the conservatism on the design analysis and in view of operational experiences, actual service life of NPPs is expected to be much longer than the design life. For PLEX, it is important to understand the excessive conservatism in the design analysis and the realistic fatigue usage factor (UF) based on the actual plant operating data in order to assess the remaining life time of RPV. To get the realistic UF, the stress analysis requires not only the actual operating process data but also the realistic thermal boundary conditions such as heat transfer coefficient. And stress analysis method must be simple in order to compute a vast number of stresses during plant life time in a short time. Therefore, Japanese BWR utilities jointly with BWR manufacturers established programs (1) to acquire plant operating data on-line for specific parameters used in stress analysis, (2) to evaluate margins in the design using measured plant data and best estimate boundary conditions for stress analysis, and (3) to establish simplified stress analysis method for fatigue evaluation. This paper describes the achievements of this research and the research activities in the future. In the program (1), on-line plant data acquisition system, named OPEDAS, has been developed and installed

  11. The Sea Monitoring Virtual Research Community (VRC) in the EVER-EST Project (a virtual research environment for the Earth Sciences).

    Foglini, Federica; Boero, Ferdinando; Guarino, Raffaele

    2016-04-01

    The EU's H2020 EVER-EST Project is dedicated to the realization of a Virtual Research Environment (VRE) for Earth Science researchers during 2015-2018. In this framework the Sea monitoring represents one of the four use case VRCs chosen to validate the EVER-EST e-infrastructure, which is aimed at representing a wide and multidisciplinary Earth Science domain. The objective of the Sea Monitoring Virtual Research Community (VRC) is to provide useful and applicable contributions to the identification and definition of variables indicated by the European Commission in the Marine Directive under the framework for Good Environment Status (GES). The European Marine Strategy Framework Directive (MSFD, http://ec.europa.eu/environment/marine/index_en.htm) has defined the descriptors for Good Environmental Status in marine waters. The first descriptor is biodiversity; the second one is the presence of non-indigenous species while the remaining nine (even when they consider physical, chemical or geological variables) require proper functioning of the ecosystem, linked to a good state of biodiversity. The Sea Monitoring VRC is direct to provide practical methods, procedures and protocols to support coherent and widely accepted interpretation of the Descriptors 1(Biodiversity), 2 (non- indigenous species), 4 (food webs) and 6 (seafloor integrity) identified in GES. In that context, the criteria and methodological standards already identified by the European Commission, and at same time considering the activities and projects in progress in the marine framework, will be taken into account. This research of practical methods to estimate and measure GES parameters requires a close cooperation among different disciplines including: biologists, geologists, geophysics, oceanographers, Earth observation experts and others. It will also require a number of different types of scientific data and observations (e.g. biology related, chemico-physical, etc.) from different inputs and sensors

    Shihao Zhou

    2016-03-01

    Full Text Available In order to achieve multi-point, highly efficient and real-time wireless transmission of data about melon fly monitoring under various temperatures and other variable environmental conditions, this paper proposes and builds a model of a melon fly monitoring system with a wireless sensor network. Combined with multi-hop wireless sensor networks suitable for Adaptive Ad Hoc Transmission Control Protocol (ADTCP algorithm, the transmission-limited congestion window is a method to reduce network congestion, simulate the aggregation node of the sensor network through a wireless transceiver platform, and finally to compile monitoring data in a central computer. The proposed scheme can effectively mitigate congestion problems of the wireless sensor network for monitoring melon flies at the aggregation node, can improve the data transmission performance of the monitoring network, and can adapt to various environmental conditions.

    2011-04-01

    Full Text Available Abstract Background Ambulatory blood pressure monitoring (ABPM is increasingly used to measure blood pressure (BP in research studies. We examined ease of use, comfort, degree of disturbance, reported adverse effects, factors associated with poor tolerability, and association of poor tolerability with data acquisition of 24-hour ABPM using the Oscar 2 monitor in the research setting. Methods Sixty adults participating in a research study of people with a history of borderline clinic BP reported on their experience with ABPM on two occasions one week apart. Poor tolerability was operationalized as an overall score at or above the 75th percentile using responses to questions adapted from a previously developed questionnaire. In addition to descriptive statistics (means for responses to Likert-scaled "0 to 10" questions and proportions for Yes/No questions, we examined reproducibility of poor tolerability as well as associations with poor tolerability and whether poor tolerability was associated with removal of the monitor or inadequate number of BP measurements. Results The mean ambulatory BP of participants by an initial ABPM session was 148/87 mm Hg. After wearing the monitor the first time, the degree to which the monitor was felt to be cumbersome ranged from a mean of 3.0 to 3.8, depending on whether at work, home, driving, or other times. The most bother was interference with normal sleeping pattern (mean 4.2. Wearers found the monitor straightforward to use (mean 7.5. Nearly 67% reported that the monitor woke them after falling asleep, and 8.6% removed it at some point during the night. Reported adverse effects included pain (32%, skin irritation (37%, and bruising (7%. Those categorized as having poor tolerability (kappa = 0.5 between sessions, p = 0.0003 were more likely to report being in fair/poor health (75% vs 22%, p = 0.01 and have elevated 24-hour BP average (systolic: 28% vs 17%, p = 0.56; diastolic: 30% vs 17%, p = 0.37.

    Oliver, J. A.; Kosmatka, J. B.; Farrar, Charles R.; Park, Gyuhae

    2007-04-01

    In order to facilitate damage detection and structural health monitoring (SHM) research for composite unmanned aerial vehicles (UAV) a specialized test-bed has been developed. This test-bed consists of four 2.61 m all-composite test-pieces emulating composite UAV wings, a series of detailed finite element models of the test-pieces and their components, and a dynamic testing setup including a mount for simulating the cantilevered operation configuration of real wings. Two of the wings will have bondline damage built in; one undamaged and one damaged wing will also be fitted with a range of embedded and attached sensors-piezoelectric patches, fiber-optics, and accelerometers. These sensors will allow collection of realistic data; combined with further modal testing they will allow comparison of the physical impact of the sensors on the structure compared to the damage-induced variation, evaluation of the sensors for implementation in an operational structure, and damage detection algorithm validation. At the present time the pieces for four wings have been fabricated and modally tested and one wing has been fully assembled and re-tested in a cantilever configuration. The component part and assembled wing finite element models, created for MSC.Nastran, have been correlated to their respective structures using the modal information. This paper details the design and manufacturing of the test-pieces, the finite element model construction, and the dynamic testing setup. Measured natural frequencies and mode shapes for the assembled cantilevered wing are reported, along with finite element model undamaged modal response, and response with a small disbond at the root of the top main spar-skin bondline.

  16. Supervisory system to monitor the neutron flux of the IPR-R1 TRIGA research reactor at CDTN

    The IPR-R1 TRIGA Mark I nuclear research reactor at the Nuclear Technology Development Center - CDTN (Belo Horizonte) is a pool type reactor. It was designed for research, training and radioisotope production. The International Atomic Energy Agency- IAEA - recommends the use of friendly interfaces for monitoring and controlling the operational parameters of nuclear reactors. This paper reports the activities for implementing a supervisory system, using LabVIEW software, with the purpose to provide the IPR-R1 TRIGA research reactor with a modern, safe and reliable system to monitor the time evolution of the power of its core. The use of the LabVIEW will introduce modern techniques, based on electronic processor and visual interface in video monitor, substituting the mechanical strip chart recorders (ink-pen drive and paper) that monitor the current neutrons flux, which is proportional to the thermal power supplied by reactor core. The main objective of the system will be to follow the evolution of the neutronic flux originated in the Linear and Logarithmic channels. A great advantage of the supervisory software nowadays, in relation to computer programs currently used in the facility, is the existence of new resources such as the data transmission and graphical interfaces by net, grid lines display in the graphs, and resources for real time reactor core video recordings. The considered system could also in the future be optimized, not only for data acquisition, but also for the total control of IPR-R1 TRIGA reactor(author)

  7. X and low energy gamma ray spectroscopy for in vivo monitoring: technical evolution and requirements for future research

    X and low energy gamma ray spectroscopy for in-vivo monitoring: Technical evolution and requirements for future research. Whole body counting remains a major tool for individual monitoring for its fast response to assess the contamination of the lung after inhalation of radio-toxic compounds. Considering actinides such as 239Pu emitting associated X and low energy γrays, in spite of improved detection methods based on large volume germanium crystals, all investigations show detection limits much too high compared to annual limit of incorporation. Based on results obtained using germanium systems, it was shown that the improvement of lung monitoring requires the development of X spectroscopy systems with resolution comparable to germanium but operating at room temperature to allow a larger detection area better adjusted to the chest volume. Among possible materials, Si and CdTe semiconductors were identified as most promising ones. (authors)

  9. Conceptual design of dual-purpose system: reactimeter and power controller for research reactors monitoring and control

    In this paper, a conceptual design for a dual purpose system for monitoring and control of research reactors is introduced. A software based reactimeter design is presented which is based on inverse reactor kinetics, along with a controller design for research reactor power maneuvering based on the reactivity trace curve (RTC) method. The reactimeter uses the on-line power measurement as an input and presents the on-line calculated reactivity. The RTC-controller uses the on-line power measurement to calculate the on-line precursors concentrations as well as the calculated reactivity from the reactimeter to present the required reactivity to control the reactor power at the specified level of operation. The simulation results of the system software design for research reactor monitoring and control is encouraging. Hence, it is possible to burn the designed software programs on a read only memory (ROM) linked to a computer mother board for I/O handling and to be tested for reactivity monitoring and reactor power control of a research reactor.

It brought forward the thought to establish factory grinder and central monitoring room to constitute Local Area Network so as that the central monitoring room could transfer information as grinding dosage and finishing of grinding wheel to operators of each grinder. Through analysis to influential factors of measurement results of that system, the paper provides with solutions. Technical tests validate that relative measurement error of that system is less than 0..5°C, which could better achieve on-line monitoring and alarm of grinding temperature and promote surface quality and productivity of grinding parts significantly.

    Within the next four years, IRIS databases will receive from the University of Wyoming and GEON recordings from nine ultra-long range Deep Seismic Sounding (DSS) projects conducted between 1970-1989 in the former Soviet Union: QUARTZ, CRATON, KIMBERLITE, METEORITE, RIFT, RUBY, BATHOLIT, BAZALT, and AGATE. Jointly sponsored by the Department of Defense and National Science Foundation, this effort will bring the unique recordings of 22 Peaceful Nuclear Explosions (PNEs) and hundreds of crustal-scale chemical shots to the broad seismological and monitoring research communities. A grid of reversed PNE profiles (plus fan recording for RUBY) covers the East European Platform, the Ural Mountains, the West Siberian Platform, the Siberian craton, and the Baikal Rift. Dense, 3-component, short-period recordings along these profiles provide a valuable source of seismic information for seismic calibration of these vast aseismic regions. DSS recordings offer unique opportunities to study propagation effects of body waves and regional seismic phases, to examine their correlation with geologic and tectonic features, to develop unusually well constrained models of the structure of the crust and upper mantle to 600-700 km depth, and to explore the variability of explosion discriminants such as spectral ratios of P- and S-waves. Though the data principally concern properties of the crust and upper mantle, some of the profiles also show strong reflections from the core-mantle boundary. We summarize the recent findings from the analysis of PNE datasets in Northern Eurasia. These results include (1) unusually detailed velocity and attenuation structure of the crust and uppermost mantle, (2) characterization of crustal attenuation through coda measurements, (3) constraints on seismic scattering from within the crust and uppermost mantle, (4) detailed imaging of the crustal basement using receiver functions, (5) continuous observations of the regional phases from the PNEs within 0

  15. The Boreal Ecosystem Research and Monitoring Sites (BERMS): A Canadian Contribution to CEOP

    Barr, A. G.; Goodison, B.; Crawford, B.

    2004-05-01

    The Boreal Ecosystem Research and Monitoring Sites (BERMS) program is providing the Canadian contribution to the WCRP Coordinated Enhanced Observing Period (CEOP) initiative of the Global Energy and Water Experiment. The BERMS super-site, which is located at the southern edge of the boreal forest in central Saskatchewan Canada, currently operates ten flux towers in a variety of ecosystems in a study area of 120 x 100 km. These sites were originally established to study the energy, water and carbon cycles of the Canadian boreal forest in relation to inter-annual climate variability for different ecosystems. The area has also been used as a super-site for developing and validating remotely-sensed information and products, especially for snow cover. It was the site of a major validation effort for snow-water equivalent determination for AMSR-E. The sites are the flagship sites in Canada for studying the energy, water and carbon cycles in a cold-climate region and are well suited to the CEOP investigation. Five of the tower flux sites were first established in 1993-4 as part of the Boreal Ecosystem-Atmosphere Study (BOREAS) and have continued since 1997 as part of the BERMS program. Five additional sites have been recently established in young forest stands following disturbance by fire and harvest, with particular focus on the carbon cycle. The data from the three mature, long-term sites in Aspen, Black Spruce and Jack Pine have been submitted to CEOP. The BERMS program has served as a model for the Canadian field flux program of network-wide standardization in instrumentation and data post-processing, data management, and government-university collaboration. The modern, automated data management system has allowed provision of data for CEOP studies in a timely manner and within the CEOP data policy and guidelines. This presentation will provide an overview of the BERMS program and related remote sensing studies as they relate to CEOP, with particular focus on data

  19. Research and development of a portable radiation monitor for use at aviation altitude

    A portable radiation monitor for the application to in-flight measurement at high altitude is developed. The monitor named as Cosmic Radiation and Energetic Particle Analyzing System (CREPAS) is composed of a phoswich-type scintillator probe coupled with a high-speed data acquisition unit connected to a note computer via USB2.0 interface. The signal waveforms are analyzed on site for the discrimination of different radiation components. In order to examine the discrimination ability, the CREPAS was exposed to accelerated proton and helium beams at National Institute of Radiological Sciences-Heavy Ion Medical Accelerator in Chiba (NIRS-HIMAC) and the data were compared to those obtained at selected accelerator facilities (JAEA-FRS, Japan Atomic Energy Agency-Takasaki Ion Accelerators for Advanced Radiation Application (JAEA-TIARA) and Osaka Univ.-RCNP). As results, it was verified that this monitor can successfully detect heavy charged particles separately from neutrons. (author)

  20. Fish Research Project Oregon; Umatilla Hatchery Monitoring and Evaluation, 1992 Annual Report.

    Keefe, MaryLouise; Carmichael, Richard W.; French, Rod A. (Oregon Department of Fish and Wildlife, Portland, OR)

    1993-03-01

    This report covers the first year of comprehensive monitoring and evaluation of the Umatilla Hatchery. As both the hatchery and the evaluation study are in the early stages of implementation, much of the information contained in this report is preliminary. The most crucial data for evaluating the success of the hatchery program, the data on post-release performance and survival, is yet unavailable. In addition, several years of data are necessary to make conclusions about rearing performance at Umatilla Hatchery. The conclusions drawn in this report should be viewed as preliminary and should be used in conjunction with additional information as it becomes available. A comprehensive fish health monitoring regimen was incorporated into the monitoring and evaluation study for Umatilla Hatchery. This is a unique feature of the Umatilla Hatchery evaluation project.

  1. NASA's Carbon Monitoring System Flux-Pilot Project: A Multi-Component Analysis System for Carbon-Cycle Research and Monitoring

    Pawson, S.; Gunson, M.; Potter, C.; Jucks, K.

    2012-01-01

    The importance of greenhouse gas increases for climate motivates NASA s observing strategy for CO2 from space, including the forthcoming Orbiting Carbon Observatory (OCO-2) mission. Carbon cycle monitoring, including attribution of atmospheric concentrations to regional emissions and uptake, requires a robust modeling and analysis infrastructure to optimally extract information from the observations. NASA's Carbon-Monitoring System Flux-Pilot Project (FPP) is a prototype for such analysis, combining a set of unique tools to facilitate analysis of atmospheric CO2 along with fluxes between the atmosphere and the terrestrial biosphere or ocean. NASA's analysis system is unique, in that it combines information and expertise from the land, oceanic, and atmospheric branches of the carbon cycle and includes some estimates of uncertainty. Numerous existing space-based missions provide information of relevance to the carbon cycle. This study describes the components of the FPP framework, assessing the realism of computed fluxes, thus providing the basis for research and monitoring applications. Fluxes are computed using data-constrained terrestrial biosphere models and physical ocean models, driven by atmospheric observations and assimilating ocean-color information. Use of two estimates provides a measure of uncertainty in the fluxes. Along with inventories of other emissions, these data-derived fluxes are used in transport models to assess their consistency with atmospheric CO2 observations. Closure is achieved by using a four-dimensional data assimilation (inverse) approach that adjusts the terrestrial biosphere fluxes to make them consistent with the atmospheric CO2 observations. Results will be shown, illustrating the year-to-year variations in land biospheric and oceanic fluxes computed in the FPP. The signals of these surface-flux variations on atmospheric CO2 will be isolated using forward modeling tools, which also incorporate estimates of transport error. The

  4. Real Time On-line Space Research Laboratory Environment Monitoring with Off-line Trend and Prediction Analysis

    Jules, Kenol; Lin, Paul P.

    2006-01-01

    One of the responsibilities of the NASA Glenn Principal Investigator Microgravity Services is to support NASA sponsored investigators in the area of reduced-gravity acceleration data analysis, interpretation and the monitoring of the reduced-gravity environment on-board various carriers. With the International Space Station currently operational, a significant amount of acceleration data is being down-linked and processed on ground for both the space station onboard environment characterization (and verification) and scientific experiments. Therefore, to help principal investigator teams monitor the acceleration level on-board the International Space Station to avoid undesirable impact on their experiment, when possible, the NASA Glenn Principal Investigator Microgravity Services developed an artificial intelligence monitoring system, which detects in near real time any change in the environment susceptible to affect onboard experiments. The main objective of the monitoring system is to help research teams identify the vibratory disturbances that are active at any instant of time onboard the International Space Station that might impact the environment in which their experiment is being conducted. The monitoring system allows any space research scientist, at any location and at any time, to see the current acceleration level on-board the Space Station via the World Wide Web. From the NASA Glenn s Exploration Systems Division web site, research scientists can see in near real time the active disturbances, such as pumps, fans, compressor, crew exercise, re-boost, extra-vehicular activity, etc., and decide whether or not to continue operating or stopping (or making note of such activity for later correlation with science results) their experiments based on the g-level associated with that specific event. A dynamic graphical display accessible via the World Wide Web shows the status of all the vibratory disturbance activities with their degree of confidence as well as

    Full Text Available Abstract Background There is increasing interest in building the capacity of researchers in low and middle income countries (LMIC to address their national priority health and health policy problems. However, the number and variety of partnerships and funding arrangements can create management problems for LMIC research institutes. This paper aims to identify problems faced by a health research institute in Bangladesh, describe two strategies developed to address these problems, and identify the results after three years of implementation. Methods This paper uses a mixture of quantitative and qualitative data collected during independent annual reviews of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B between 2006 and 2010. Quantitative data includes the number of research activities according to strategic priority areas, revenues collected and expenditure. Qualitative data includes interviews of researchers and management of ICDDR,B, and of research users and key donors. Data in a Monitoring and Evaluation Framework (MEF were assessed against agreed indicators. Results The key problems faced by ICDDR,B in 2006 were insufficient core funds to build research capacity and supporting infrastructure, and an inability to direct research funds towards the identified research priorities in its strategic plan. Two strategies were developed to address these problems: a group of donors agreed to provide unearmarked pooled core funding, and accept a single common report based on an agreed MEF. On review after three years, there had been significant increases in total revenue, and the ability to allocate greater amounts of money on capacity building and infrastructure. The MEF demonstrated progress against strategic objectives, and better alignment of research against strategic priorities. There had also been changes in the sense of ownership and collaboration between ICDDR,B's management and its core donors. Conclusions The

    Paul Higley; J. Robert Woolsey; Ralph Goodman; Vernon Asper; Boris Mizaikoff; Angela Davis

    2004-03-01

    A Consortium, designed to assemble leaders in gas hydrates research, has been established at the University of Mississippi's Center for Marine Resources and Environmental Technology, CMRET. The primary objective of the group is to design and emplace a remote monitoring station on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station allows for the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. Establishment of the Consortium has already succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in this relatively new research arena. Complementary expertise, both scientific and technical, has been assembled to innovate research methods and construct necessary instrumentation. As funding for this project, scheduled to commence December 1, 2002, had only been in place for less than half of the reporting period, project progress has been less than for other reporting periods. Nevertheless, significant progress has been made and several cruises are planned for the summer/fall of 2003 to test equipment, techniques and compatibility of systems. En route to reaching the primary goal of the Consortium, the establishment of a monitoring station on the sea floor, the following achievements have been made: (1) Progress on the vertical line array (VLA) of sensors: Software and hardware upgrades to the data logger for the prototype vertical line array, including enhanced programmable gains, increased sampling rates, improved surface communications, Cabling upgrade to allow installation of positioning

  11. Research of on-line monitoring method for insulation condition of power transformer bushing

    Xia, Jiuyun; Qian, Zheng; Yu, Hao; Yao, Junda

    2016-01-01

    The power transformer is the key equipment of the power system; its insulation condition will directly influence the security and reliability of the power system. Thus, the on-line monitoring of power transformer is urgently required in order to guarantee the normal operation of the power system. Moreover, the dielectric loss factor is a significant parameter reflecting the condition of transformer bushing, so the on-line measurement of dielectric loss factor is really important. In this paper, the phase-to-phase comparison method is selected as the on-line monitoring method based on the overall analysis and discussion of the existing on-line monitoring methods. At first, the harmonic analysis method is utilized to calculate the dielectric loss of each phase of the three-phase transformer bushing, and then the differences of dielectric loss between every two phases are calculated and analyzed. So the insulation condition of each bushing could be achieved based on the careful analysis of different phase-to-phase dielectric loss. The simulation results of phase-to-phase comparison method are carried out in this paper, and the validity is verified. At last, this method is utilized in an actual equipment of on-line monitoring.

The future of monitoring in clinical research – a holistic approach: Linking risk-based monitoring with quality management principles [Die Zukunft des Monitorings in der Klinischen Forschung – ganzheitlich gesehen: Die Abhängigkeiten zwischen Risiko-basiertem Monitoring und Qualitätsmanagement

    Leptien, Sabine

    2013-02-01

    Full Text Available [english] Since several years risk-based monitoring is the new “magic bullet” for improvement in clinical research. Lots of authors in clinical research ranging from industry and academia to authorities are keen on demonstrating better monitoring-efficiency by reducing monitoring visits, monitoring time on site, monitoring costs and so on, always arguing with the use of risk-based monitoring principles. Mostly forgotten is the fact, that the use of risk-based monitoring is only adequate if all mandatory prerequisites at site and for the monitor and the sponsor are fulfilled.Based on the relevant chapter in ICH GCP (International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use – Good Clinical Practice this publication takes a holistic approach by identifying and describing the requirements for future monitoring and the use of risk-based monitoring. As the authors are operational managers as well as QA (Quality Assurance experts, both aspects are represented to come up with efficient and qualitative ways of future monitoring according to ICH GCP.[german] Seit einigen Jahren wird von den verschiedensten Autoren – aus den industriellen, akademischen oder behördlichen Bereichen der Klinischen Forschung – das Risiko-basierte Monitoring fast wie eine Wunderformel beschworen und bewertet.

  17. On-line use of personal computers to monitor and evaluate important parameters in the research reactor DHRUVA

    The on-line use of Personal Computers in research reactors, with custom made applications for aiding the operators in analysing plant conditions under normal and abnormal situations, has become extremely popular. A system has been developed to monitor and evaluate important parameters for the research reactor DHRUVA, a 100 MW research reactor located at the Bhabha Atomic Research Centre, Trombay. The system was essentially designed for on-line computation of the following parameters: reactor thermal power, reactivity load due to Xenon, core reactivity balance and performance monitoring of shut-down devices. Apart from the on-line applications, the system has also been developed to cater some off-line applications with Local Area Network in the Dhruva complex. The microprocessor based system is designed to function as an independent unit, parallel dumping the acquired data to a PC for application programmes. The user interface on the personal computer is menu driven application software written in 'C' language. The main input parameters required for carrying out the options given in the above menu are: Reactor power, Moderator level, Coolant inlet temperature to the core, Secondary coolant flow rate, temperature rise of secondary coolant across the heat exchangers, heavy water level in the Dump tank and Drop time of individual shut off rods.

    2010-11-01

    A new method using oil atomic spectrometric analysis technology to monitor the mechanical wear state was proposed. Multi-dimensional time series model of oil atomic spectrometric data of running-in period was treated as the standard model. Residues remained after new data were processed by the standard model. The residues variance matrix was selected as the features of the corresponding wear state. Then, high dimensional feature vectors were reduced through the principal component analysis and the first three principal components were extracted to represent the wear state. Euclidean distance was computed for feature vectors to classify the testing samples. Thus, the mechanical wear state was identified correctly. The wear state of a specified track vehicle engine was effectively identified, which verified the validity of the proposed method. Experimental results showed that introducing the multi-dimensional time series model to oil spectrometric analysis can fuse the spectrum data and improve the accuracy of monitoring mechanical wear state.

  20. Research and improvement of monitoring system for gaseous effluent in Qinshan Nuclear Power Plant

    The long horizontal and vertical sampling pipelines are used in the gaseous radioactive effluent monitoring system in Qinshan Nuclear Power Plant, so there is design deficiency for the monitoring of gaseous effluent. The long sampling pipelines, especially horizontal pipe, will result in the losing of sampling particulate and iodine. By means of modification, the sampler for particulate and iodine is moved into the small corrective room at the bottom of the stack, therefore, 85.4 meters long horizontal sampling pipe is cancelled, only 70.6 meter long vertical sampling pipe is reserved. The test and assessment result indicated that the corrective factor of the radioactive iodine sampling is 1.65. For radioactive particulate, according to conservative estimate, the corrective factor is less than 1.65 under accident condition. During normal operation, the particulate is consisted of tiny particles, and the corrective factor is 1.1. (authors)

  2. Research and development of a portable radiation monitor for use at aviation altitude

    A portable radiation monitor named as ''CREPAS'' for the application to in-flight measurement at high altitude has been developed. The signal waveforms are analyzed on site for the discrimination of different radiation components obtained with a phoswich-type scintillation probe. In the present study, the discrimination ability of a new probe was tested for accelerated proton and helium-ion beams at National Institute of Radiological Sciences-Heavy Ion Medical Accelerator in Chiba (NIRS-HMAC) in comparison with the previous probe. It was verified so far that the new monitor can more successfully determine proton energies, separated from helium ions. The data were compared also to those for neutrons at JAEA-Takasaki Ion Accelerators for Advanced Radiation Application (TIARA). (author)

    Land subsidence is harmful to urban roads and bridges, municipal pipelines and tall buildings, etc. As an international metropolis with rapid development, it is very important to find a real-time and efficient method to monitor the land subsidence. The GNSS technology, based on the Shanghai Continuously Operating Reference System (SHCORS), can be used to accurately and contiguously monitor land subsidence. In this work, we analyze the land subsidence tendency of Shanghai area by the space geodetic post processing software QOCA, based on the vertical deformation time series of the ten CORS stations from 2007 to 2010. We use loading models to remove the vertical deformation caused by the geophysical factors, such as the atmospheric pressure, the mass load of snow covers and soil humidity, the non-tidal oceanic mass load, rock' s thermal expansion and shrink and so on, then study the possible factors, which cause land subsidence, such as the over pumping groundwater activities etc.

    A large part of the Mediterranean coastlines are strongly affected by coastal erosion. This is mainly due to human impact, natural hazards and their mutual interaction. All along the Regione Liguria coastlines (Northwestern Mediterranean), significant problems of coastal erosion are reported since the '60s. In this study, we focus on the coastal area between Albenga and Savona, where dramatic coastal retreat of ~2 m y-1 has been inferred from comparison of historic maps and older aerial pictures. Beach monitoring is essential in order to understand the mechanisms of evolution of soft coasts, and the rates of erosion. Traditional beach monitoring techniques involve topographic and bathymetric surveys of the emerged and submerged beach, and/or aerial photos repeated in time and compared through geographical information systems. A major problem of this kind of approach is the high economic cost. This often leads to increase the time lag between successive monitoring campaigns to reduce survey costs, with the consequence of fragmenting the information available for coastal zone management. MIRAMar is a project funded by Regione Liguria through the PO CRO European Social Fund, and it has two main objectives: i) to study and develop an innovative technique, relatively low-cost, to monitor the evolution of the shoreline using low-altitude Unmanned Aerial Vehicle (UAV) photos; ii) to study the impact of different type of storm events on a vulnerable coastal tract subject to coastal erosion using also the data collected by the UAV instrument. To achieve these aims we use a drone with its hardware and software suit, traditional survey techniques (bathymetric surveys, topographic GPS surveys and GIS techniques) and we implement a numerical modeling chain (coupling hydrodynamic, wave and sand transport modules) in order to study the impact of different type of storm events on a vulnerable coastal tract subject to coastal erosion.

    2016-01-01

    As the main electrical component for the reactive power compensation, the power capacitors are widely applied in many fields. And since the insulation condition of power capacitor could be identified accurately by using the on-line monitoring system, it attracts more and more attentions in recent years. In this paper, a novel on-line monitoring equipment for power capacitor based on wireless sensor network is presented. The operation data which includes the current and voltage of every capacitor is collected at first, and then the FFT is utilized to calculate the amplitude and phase of every signal, thus the insulation condition and the fault symptom could all be diagnosed accurately by analyzing the FFT results. In order to realize the effective isolation and the reliable communication between the sensing part and the merging unit, the wireless sensor network is adopted. The high reliability and transmission rate could be realized by using 2.4GHz UHF and 5GHz ISM radio bands. Thus the on-line monitoring system could be manufactured, and the lab test is carried at last. The testing results illustrate that this system could satisfy the requirement of on-site real-time measurement.

  10. Research on Linear Wireless Sensor Networks Used for Online Monitoring of Rolling Bearing in Freight Train

    This paper presents a Wireless Sensor Networks (WSNs) technique for the purpose of on-line monitoring of rolling bearing in freight train. A new technical scheme including the arrangements of sensors, the design of sensor nodes and base station, routing protocols, signal acquirement, processing and transmission is described, and an on-line monitoring system is established. Considering the approximately linear arrangements of cars and the running state of freight train, a linear topology structure of WSNs is adopted and five linear routing protocols are discussed in detail as to obtain the desired minimum energy consumption of WSNs. By analysing the simulation results, an optimal multi-hop routing protocol named sub-section routing protocol according to equal distance is adopted, in which all sensor nodes are divided into different groups according to the equal transmission distance, the optimal transmission distance and number of hops of routing protocol are also studied. We know that the communication consumes significant power in WSNs, so, in order to save the limit power supply of WSNs, the data compression and coding scheme based on lifting integer wavelet and embedded zerotree wavelet (EZW) algorithms is studied to reduce the amounts of data transmitted. The experimental results of rolling bearing have been given at last to verify the effectiveness of data compression algorithm. The on-line monitoring system of rolling bearing in freight train will be applied to actual application in the near future.

  12. Research on a Banknote Printing Wastewater Monitoring System based on Wireless Sensor Network

    In this paper, a banknote printing wastewater monitoring system based on WSN is presented in line with the system demands and actual condition of the worksite for a banknote printing factory. In Physical Layer, the network node is a nRF9e5-centric embedded instrument, which can realize the multi-function such as data collecting, status monitoring, wireless data transmission and so on. Limited by the computing capability, memory capability, communicating energy and others factors, it is impossible for the node to get every detail information of the network, so the communication protocol on WSN couldn't be very complicated. The competitive-based MACA (Multiple Access with Collision Avoidance) Protocol is introduced in MAC, which can decide the communication process and working mode of the nodes, avoid the collision of data transmission, hidden and exposed station problem of nodes. On networks layer, the routing protocol in charge of the transmitting path of the data, the networks topology structure is arranged based on address assignation. Accompanied with some redundant nodes, the network performances stabile and expandable. The wastewater monitoring system is a tentative practice of WSN theory in engineering.

    2016-01-01

    Full Text Available Reliability is an essential factor for GPS navigation system. Therefore, an integrity monitoring is considered as one of the most important parts for a navigation system. GPS receiver autonomous integrity monitoring (RAIM technique can detect and isolate fault satellite. Based on particle filter, a novel RAIM method was proposed to detect two-satellite faults of the GPS signal by using hierarchical particle filter. It can deal with any system nonlinear and any noise distributions. Because GNSS measurement noise does not follow the Gaussian distribution perfectly, the particle filter can estimate the posterior distribution more accurately. In order to detect fault, the consistency test statistics is established through cumulative log-likelihood ratio (LLR between the main and auxiliary particle filters (PFs.Specifically, an approach combining PF with the hierarchical filter is used in the process of two-satellite faults. Through GPS real measurement, the performance of the proposed GPS two-satellite faults detection algorithm was illustrated. Some simulation results are given to evaluate integrity monitoring performance of the algorithm. Validated by the real measurement data, the results show that the proposed algorithm can successfully detect and isolate the faulty satellite in the case of non-Gaussian measurement noise.

  17. Processing deficits in monitoring analog and digital displays: Implications for attentional theory and mental-state estimation research

    Payne, David G.; Gunther, Virginia A. L.

    1988-01-01

    Subjects performed short term memory tasks, involving both spatial and verbal components, and a visual monitoring task involving either analog or digital display formats. These two tasks (memory vs. monitoring) were performed both singly and in conjunction. Contrary to expectations derived from multiple resource theories of attentional processes, there was no evidence that when the two tasks involved the same cognitive codes (i.e., either both spatial or both verbal/linguistics) there was more of a dual task performance decrement than when the two tasks employed different cognitive codes/processes. These results are discussed in terms of their implications for theories of attentional processes and also for research in mental state estimation.

  19. Groundwater monitoring program plan and conceptual site model for the Al-Tuwaitha Nuclear Research Center in Iraq.

    Copland, John Robin; Cochran, John Russell

    2013-07-01

    The Radiation Protection Center of the Iraqi Ministry of Environment is developing a groundwater monitoring program (GMP) for the Al-Tuwaitha Nuclear Research Center located near Baghdad, Iraq. The Al-Tuwaitha Nuclear Research Center was established in about 1960 and is currently being cleaned-up and decommissioned by Iraq's Ministry of Science and Technology. This Groundwater Monitoring Program Plan (GMPP) and Conceptual Site Model (CSM) support the Radiation Protection Center by providing:A CSM describing the hydrogeologic regime and contaminant issues,recommendations for future groundwater characterization activities, anddescriptions of the organizational elements of a groundwater monitoring program. The Conceptual Site Model identifies a number of potential sources of groundwater contamination at Al-Tuwaitha. The model also identifies two water-bearing zones (a shallow groundwater zone and a regional aquifer). The depth to the shallow groundwater zone varies from approximately 7 to 10 meters (m) across the facility. The shallow groundwater zone is composed of a layer of silty sand and fine sand that does not extend laterally across the entire facility. An approximately 4-m thick layer of clay underlies the shallow groundwater zone. The depth to the regional aquifer varies from approximately 14 to 17 m across the facility. The regional aquifer is composed of interfingering layers of silty sand, fine-grained sand, and medium-grained sand. Based on the limited analyses described in this report, there is no severe contamination of the groundwater at Al-Tuwaitha with radioactive constituents. However, significant data gaps exist and this plan recommends the installation of additional groundwater monitoring wells and conducting additional types of radiological and chemical analyses.

    2006-06-01

    The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The Consortium is administered by the Center for Marine Resources and Environmental Technology, CMRET, at the University of Mississippi. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2007, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the marine environment, including sea water and sea-floor sediments, on a more-or-less continuous basis over an extended period of time. In 2005, biological monitoring, as a means of assessing environmental health was added to the mission of the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has now achieved a microbial dimension in addition to the geophysical and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, had to be postponed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Every effort was made to locate and retain the services of a suitable vessel and submersibles or Remotely Operated Vehicles (ROVs) following the storms and the loss of the contracted vessel

  1. Reliability of Sleep Measures from Four Personal Health Monitoring Devices Compared to Research-Based Actigraphy and Polysomnography.

    Mantua, Janna; Gravel, Nickolas; Spencer, Rebecca M C

    2016-01-01

    Polysomnography (PSG) is the "gold standard" for monitoring sleep. Alternatives to PSG are of interest for clinical, research, and personal use. Wrist-worn actigraph devices have been utilized in research settings for measures of sleep for over two decades. Whether sleep measures from commercially available devices are similarly valid is unknown. We sought to determine the validity of five wearable devices: Basis Health Tracker, Misfit Shine, Fitbit Flex, Withings Pulse O2, and a research-based actigraph, Actiwatch Spectrum. We used Wilcoxon Signed Rank tests to assess differences between devices relative to PSG and correlational analysis to assess the strength of the relationship. Data loss was greatest for Fitbit and Misfit. For all devices, we found no difference and strong correlation of total sleep time with PSG. Sleep efficiency differed from PSG for Withings, Misfit, Fitbit, and Basis, while Actiwatch mean values did not differ from that of PSG. Only mean values of sleep efficiency (time asleep/time in bed) from Actiwatch correlated with PSG, yet this correlation was weak. Light sleep time differed from PSG (nREM1 + nREM2) for all devices. Measures of Deep sleep time did not differ from PSG (SWS + REM) for Basis. These results reveal the current strengths and limitations in sleep estimates produced by personal health monitoring devices and point to a need for future development. PMID:27164110

    2015-12-01

    Volcanic eruptions pose serious hazards to aircraft in flight and to people and facilities on the ground. Fortunately, some aspects of volcanic activity are predictable, or at least predictable enough that warning signs of impending activity can be used to warn the public about elevated levels of hazard. The study of and monitoring of active volcanoes is inherently multi-disciplinary, a microcosm of earth sciences. Many different types of data must be brought together to study active volcanic systems. A volcano observatory brings together experts in various disciplines to work on a common mission of providing accurate and timely warnings of potential future activity, notifications of ongoing activity, and assessments of hazards and impacts that may result if an eruption escalates. This requires using an array of data including seismic, geodetic, remote sensing, gas monitoring, thermal imaging, and visual observations. Effective communication of scientific information to the public is of critical importance. The Alaska Volcano Observatory pioneered the use of a simple green-yellow-orange-red color code to communicate the level of concern about activity at individual volcanoes, and this color code has been refined and adopted by all US volcano observatories. The use of an easily understood color code and other standard notifications makes for more effective communication with other agencies, emergency managers, and the public.

    Zhang, Xia; Fu, Jie; Yu, Miao; Zhang, Nanqing; Mei, Weipeng

    2013-01-01

    In recent years, hazmat transportation's accidents occur frequently and the road safety transportation issues become increasingly prominent with the demanding for road transport of hazardous goods. However, there are too many types of hazardous goods and every single type has one or several characters. Some of the parameters which are related to security need to be monitored when it comes to transportation. For the tough problem above, this paper presents a sensor data collection technical scheme that is based on the RS485 bus technology. Sensor modules are distributed at various parts of the lorry in order to measure the critical state information of the transporting goods. More importantly, users can get various critical state information they want which corresponds with the transported hazmat by putting different types of sensor modules onto RS485 bus. Combine the above technical scheme with GPS technology and CDMA radio transmission technology, the key state information and location information of the hazmat can be transferred to the supervision and management center to meet the demand of state monitoring.

    2016-01-01

    Full Text Available The deformation monitoring algorithm with millimeter level precision based on BeiDou Navigation Satellite System (BDS was researched. The TurboEdit method was improved to detect small cycle slips, e.g. 1 cycle. Focusing on BDS constellation, a more efficient algorithm used to construct double-differenced observations was developed. The Bootstrap+Decision function method was utilized to improve the probability of biases fixing. Based on the improved algorithm above, a deformation monitoring software based on BDS was achieved. Afterwards, the availability of BDS in the field of deformation monitoring was analyzed in terms of satellites distribution and precision and accuracy of solutions, utilizing the observations acquired from the experimental platform. The conclusion was drawn that currently BDS is similar to GPS in terms of satellites distribution in the test area. The precision of short baselines derived from BDS is better than 1 mm for the horizontal components, better than 2 mm for the vertical components, which is still a little lower than GPS.

  10. A Simple and Low-Cost Monitoring System to Investigate Environmental Conditions in a Biological Research Laboratory.

    Gurdita, Akshay; Vovko, Heather; Ungrin, Mark

    2016-01-01

    Basic equipment such as incubation and refrigeration systems plays a critical role in nearly all aspects of the traditional biological research laboratory. Their proper functioning is therefore essential to ensure reliable and repeatable experimental results. Despite this fact, in many academic laboratories little attention is paid to validating and monitoring their function, primarily due to the cost and/or technical complexity of available commercial solutions. We have therefore developed a simple and low-cost monitoring system that combines a "Raspberry Pi" single-board computer with USB-connected sensor interfaces to track and log parameters such as temperature and pressure, and send email alert messages as appropriate. The system is controlled by open-source software, and we have also generated scripts to automate software setup so that no background in programming is required to install and use it. We have applied it to investigate the behaviour of our own equipment, and present here the results along with the details of the monitoring system used to obtain them. PMID:26771659

    LIU Quan; QU Xuehong; ZHOU Henglin; LONG Yihong

    2006-01-01

    This paper designed an embedded video monitoring system using DSP(Digital Signal Processing) and ARM(Advanced RISC Machine). This system is an important part of self-service operation of numerical control machine tools. At first the analog input signals from the CCD(Charge Coupled Device) camera are transformed into digital signals, and then output to the DSP system, where the video sequence is encoded according to the new generation image compressing standard called H.264. The code will be transmitted to the ARM system through xBus, and then be packed in the ARM system and transmitted to the client port through the gateway. Web technology, embedded technology and image compressing as well as coding technology are integrated in the system, which can be widely used in self-service operation of numerical control machine tools and intelligent robot control areas.

  13. Basic research for development of the beam profile monitor based on a Faraday cup array system

    Park, Mook-Kwang

    2015-10-01

    The basic design used to develop a beam profile monitor based on a Faraday cup array (FCA), which has the advantages of high robustness, reliability, and long-term stability, along with the ability to measure the ion current over a wide dynamic range, was developed. The total system is divided into three parts: i.e., a faraday cup, measuring electronics, and a display program part. The FCA was considered to consist of a collimator, suppressor, insulator frame, and 64 (8 × 8 array) tiny Faraday cups (FC). An electronic circuit using a multiplexer was applied to effectively address many signal lines and the printed circuit board (PCB) was designed to be divided into three parts, i.e., an electrode PCB (ELEC PCB), capacitance PCB (CAP PCB), and control PCB (CON PCB).

  14. Nuclear safeguards for an underground final repository - Research for acoustic-seismic monitoring

    Final repositories for spent nuclear fuel need to be put under safeguards of the International Atomic Energy Agency (IAEA) to detect potential access, during and after the emplacement phase. Tasked by the German Support Programme for the IAEA we have measured acoustic and seismic signals from various mining activities in the Gorleben exploratory mine. Geophone spectra show excitation up to several kHz, often with considerable broad-band content. With periodic machinery harmonic series appear. Seismic signal strengths from different sources vary by three (including blast shots by six) orders of magnitude, in power-law fits the decrease with distance is with exponents -2 to -0.8. Many sources could be detected by amplitude at several 100 m distance, blasts at several km. By a ring of underground geophones around a repository in salt monitoring for undeclared activities seems principally possible.

  15. Gas bubble trauma monitoring and research of juvenile salmonids. 1995 Annual report

    This report describes laboratory and field monitoring studies of gas bubble trauma (GBT) in migrating juvenile salmonids in the Snake and Columbia rivers. The first chapter describes laboratory studies of the progression of GBT signs leading to mortality and the use of the signs for GBT assessment. The progression and severity of GBT signs in juvenile salmonids exposed to different levels of total dissolved gas (TDG) and temperatures was assessed and quantified. Next, the prevalence, severity, and individual variation of GBT signs was evaluated to attempt to relate them to mortality. Finally, methods for gill examination in fish exposed to high TDG were developed and evaluated. Primary findings were: (1) no single sign of GBT was clearly correlated with mortality, but many GBT signs progressively worsened; (2) both prevalence and severity of GBT signs in several tissues is necessary; (3) bubbles in the lateral line were the earliest sign of GBT, showed progressive worsening, and had low individual variation but may develop poorly during chronic exposures; (4) fin bubbles had high prevalence, progressively worsened, and may be a persistent sign of GBT; and (5) gill bubbles appear to be the proximate cause of death but may only be relevant at high TDG levels and are difficult to examine. Chapter Two describes monitoring results of juvenile salmonids for signs of GBT. Emigrating fish were collected and examined for bubbles in fins and lateral lines. Preliminary findings were: (1) few fish had signs of GBT, but prevalence and severity appeared to increase as fish migrated downstream; (2) there was no apparent correlation between GBT signs in the fins, lateral line, or gills; (3) prevalence and severity of GBT was suggestive of long-term, non-lethal exposure to relatively low level gas supersaturated water; and (4) it appeared that GBT was not a threat to migrating juvenile salmonids. 24 refs., 26 figs., 3 tabs

    The Poverty Alleviation Monitoring and Evaluation System (PAMES) is introduced in this paper. The authors present environment platform selection, and details of system design and realization. Different with traditional research of poverty alleviation, this paper develops a new analytical geo-visualization approach to study the distribution and causes of poverty phenomena within Geographic Information System (GIS). Based on the most detailed poverty population data, the spatial location and population statistical indicators of poverty village in Jiangxi province, the distribution characteristics of poverty population are detailed. The research results can provide much poverty alleviation decision support from a spatial-temporal view. It should be better if the administrative unit of poverty-stricken area to be changed from county to village according to spatial distribution pattern of poverty.

  17. Current Status and Future Research Directions in Monitoring Vigilance of Individual or Mass Audience in Monotonous Working Environment

    B. F. Momin

    2012-06-01

    Full Text Available Working in monotonous environment often causes lack of concentration or fatigue in an operator and many times such non-vigilance leads to accidents. Therefore early detection of fatigued state has become essential in monotonous working environments like driving vehicle, operating machines etc. Such fatigued state often gets developed gradually and can be identified by certain symptoms. Different types of symptoms help in modelling non-vigilance in different ways. This paper reviews and compares current status of research in modelling fatigue where fatigue is modelled using probabilistic models, machine learning models, finite state machine etc. The paper also presents possible future research directions in the same field like identifying non-fatigue non-vigilance mental states, extending non-vigilance monitoring for mass audience etc.

  18. Thirty Years of Participatory Watershed Research: Engaging Citizen Scientists Through the NH Lakes Lay Monitoring Program (Invited)

    Schloss, J. A.

    2009-12-01

    While it began as a citizen water quality monitoring program to document long-term trends and find problem areas impacting lake watersheds the New Hampshire Lakes Lay Monitoring Program soon evolved into a model effort for engaging the participants to help investigate a wide range of scientific questions primarily derived through their concerns. As a true participatory effort, community members were involved in the design as well as the implementation of the research and also in the interpretation of the results. The research outcomes have provided benefits to both the local and scientific communities. In many cases productive partnerships between the research community and participants were initiated that continue to last to this day. In addition, participants have been empowered through their experience and have become local experts and community leaders. Collaborative research projects to date have explored fish condition, recreational impacts, nutrient loadings from watershed land use, morphometric determinants of lake productivity, ground truth for remote sensing of water quality, biological controls for invasive aquatic plants, in-lake resource co-occurrences, and cyanobacteria bloom toxin ecology. Participants were also instrumental in confirming a more accurate method for water clarity measurement. Results have not only provided the community with the information they require for the informed local stewardship of their resources but also have been useful to state agencies and decision-makers. Our success can be attributed to the development of quality assured methods acceptable to regional and state agencies, the cost efficiencies of using volunteer scientists, support from the University and Cooperative Extension, capturing the "local expertise" of our participants, providing timely feedback and support, and making sure the study results are reported back to the local community through the participants involved.

  19. National and Regional Scale Rice Crop Monitoring in Asia with the RIICE and PRISM Projects: From Research to Operation

    Nelson, A.; Quicho, E. D.; Maunahan, A. A.; Setiyono, T. D.; Raviz, J. V.; Rala, A. B.; Laborte, A. G.; Holecz, F.; Collivignarelli, F.; Gatti, L.; Barbieri, M.; Mabalay, M. R. O.; De Dios, J. L.; Quilang, E. J. P.

    2015-12-01

    In recent years, remote sensing based mapping and monitoring of the rice crop have been demonstrated in many pilot studies and research sites - mainly in Asia - using both optical and SAR sensors and ground based observations. These efforts have been partly driven by the high demand for more timely, more detailed and more accurate information on the rice crop for applications in both public and private sector, such as food security policy, crop and land management, infrastructure investment and crop insurance. The basic premise being that better access to better information leads to eventual benefits for both producers and consumers through better investment and management at all levels. To realise these benefits means scaling up this work to national and regional levels. This presentation summarises the progress of two related projects in Asia: RIICE (Remote Sensing-based Information and Insurance in emerging Economies) and PRISM (Philippine Rice Information SysteM) that are making the transition from research to operation with the support of national governments and international donors. The presentation focuses on the technology, the partnerships, the achievements and the challenges in embedding both the capacity and the technology for remote sensing based monitoring of rice in countries in South and South East Asia. We highlight several aspects which are essential for a successful transition to a sustainable operational status and lessons learned in each country where the two projects have been operating.

  20. Data of long term hydro-pressure monitoring on Mizunami Underground Research Laboratory project for fiscal year 2012

    Japan Atomic Energy Agency (JAEA) has been conducting Mizunami Underground Research Laboratory (MIU) Project, which is a broad scientific study of the deep geological environment as a basis of research and development for geological disposal of high-level radioactive waste, in order to establish comprehensive techniques for the investigation, analysis and assessment of the deep geological environment in crystalline rock. The MIU Project has three overlapping phases: Surface-based Investigation phase (Phase I), Construction phase (Phase II), and Operation phase (Phase III), with a total duration of over 20 years. The main goals of the MIU Project from Phase I through to Phase III are: to establish techniques for investigation, analysis and assessment of the deep geological environment, and to develop a range of engineering for deep underground application. Currently, the project is being carried out under the Phase II and III. One of the Phase II goals is set to develop and revise models of the geological environment using the investigation results obtained during excavation, and to determine and assess the changes in the geological environment in response to excavation. The long term hydro-pressure monitoring has been continued to achieve the Phase II goals. This report describes the results of the long term hydro-pressure monitoring from April 2012 to March 2013. A CD-ROM is attached as an appendix. (J.P.N.)

  1. Research and Technology Development to Advance Environmental Monitoring, Food Systems, and Habitat Design for Exploration Beyond Low Earth Orbit

    Sullivan, Thomas A.; Perchonek, M. H.; Ott, C. M.; Kaiser, M. K.

    2011-01-01

    Exploration missions will carry crews far beyond the relatively safe environs of cis-lunar space. Such trips will have little or no opportunity for resupply or rapid aborts and will be of a duration that far exceeds our experience to date. The challenges this imposes on the requirements of systems that monitor the life support and provide food and shelter for the crew are the focus of much research within the Human Research Program. Making all of these technologies robust and reliable enough for multi-year missions with little or no ability to run for home calls for a thorough understanding of the risks and impacts of failure. The way we currently monitor for microbial contamination of water, air, and surfaces, by sampling and growing cultures on nutrient media, must be reconsidered for exploration missions which have limited capacity for consumables. Likewise, the shelf life of food must be increased so that the nutrients required to keep the crewmembers healthy do not degrade over the life of the mission. Improved formulations, preservation, packaging, and storage technologies are all being investigated for ways slow this process or replace stowed food with key food items grown fresh in situ. Ensuring that the mass and volume of a spacecraft are used to maximum efficiency calls for infusing human factors into the design from its inception to increase efficiency, improve performance, and retain robustness toward operational realities. Integrating the human system with the spacecraft systems is the focus of many lines of investigation.

  2. Effects of increasing CO2 on trees and intensively monitored plots: research needs in view of future ecosystem studies

    Michopoulos P

    2011-08-01

    Full Text Available The intensively monitored plots in Europe have offered a lot of information with regard to the dynamics of forest ecosystems. A large stock of data is already available as an input to ecological models. The carbon sequestration challenge is a little different from others. It requires long-term studies and additional information from what already exists. So far, apart from the determination of organic C in soils, research in the intensively monitored plots has mainly focused on above ground processes, i.e., crown assessment, phenology, deposition, litterfall, tree growth, and foliar chemistry. All these parameters are valuable and will continue to be so. However, according to the latest literature reviews on the subject, the key to understanding the reaction of trees to climate change lies in the dynamics of belowground processes. Information is needed on nitrogen mineralization rates, soil respiration rates and labile carbon forms in soils. If we take into account that countries pay for their carbon emissions and are paid for carbon sequestration, a research like this can be worth doing. Most importantly, the ecological models can be enriched and therefore be more precise in predicting tree response to climate change.

  4. Support of Gulf of Mexico Hydrate Research Consortium: Activities to Support Establishment of a Sea Floor Monitoring Station Project

    Carol Lutken

    2006-09-30

    The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The Consortium is administered by the Center for Marine Resources and Environmental Technology, CMRET, at the University of Mississippi. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2007, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the marine environment, including sea water and sea-floor sediments, on a more-or-less continuous basis over an extended period of time. In 2005, biological monitoring, as a means of assessing environmental health, was added to the mission of the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has now achieved a microbial dimension in addition to the geophysical, geological, and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, had to be postponed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. The CMRET has conducted several research cruises during this reporting period

  8. Maintenance activities based on condition monitoring at research reactor 'JRR-3'

    The construction of the research reactor 'JRR-3' started for the purpose of development of nuclear technology and first critical was achieved in 1961. A large scale modification was done to meet more demand from researchers in 1990. So far about operation of JRR-3, there have been no big troubles and JRR-3 has been under stable operation for more than 15 years from the modification. But it is necessary to investigate a maintenance methods considering high aging. On the contrary, it is difficult to keep present maintenance because of the reduction of the budget and staff. In such situation, we should find an effective maintenance method which does not spoil safety and reliability. In this presentation, our investigation of the effective maintenance and actual maintenance activities on JRR-3 are shown. (author)

  9. Progress in Understanding Harmful Algal Blooms: Paradigm Shifts and New Technologies for Research, Monitoring, and Management

    Anderson, Donald M.; Cembella, Allan D.; Hallegraeff, Gustaaf M.

    2012-01-01

    The public health, tourism, fisheries, and ecosystem impacts from harmful algal blooms (HABs) have all increased over the past few decades. This has led to heightened scientific and regulatory attention, and the development of many new technologies and approaches for research and management. This, in turn, is leading to significant paradigm shifts with regard to, e.g., our interpretation of the phytoplankton species concept (strain variation), the dogma of their apparent cosmopolitanism, the role of bacteria and zooplankton grazing in HABs, and our approaches to investigating the ecological and genetic basis for the production of toxins and allelochemicals. Increasingly, eutrophication and climate change are viewed and managed as multifactorial environmental stressors that will further challenge managers of coastal resources and those responsible for protecting human health. Here we review HAB science with an eye toward new concepts and approaches, emphasizing, where possible, the unexpected yet promising new directions that research has taken in this diverse field.

  13. Using the Citizen Science Picture Post Project as the Foundation for Campus Environmental Monitoring by Undergraduate Student Researchers

    Bowen, K.; Guertin, L. A.

    2014-12-01

    Penn State Brandywine is utilizing the citizen science Picture Post network as a foundation for collecting campus environmental data and for undergraduate student research investigations. The Picture Post is an environmental monitoring project a part of Digital Earth Watch, a citizen science initiative funded by NASA. Picture Post creates opportunities for educators and community members to take digital photos from octagonal platforms on posts registered as part of the Picture Post national network and then share these photos online. Penn State Brandywine joined the Picture Post project May 27, 2014, to begin a long-term monitoring program, starting with an environmental baseline of the campus landscape. Four post locations were selected on campus based upon projected major construction projects. Photos at each post are being taken by students on a weekly basis and uploaded to the Picture Post website. The campus community and beyond are also being encouraged to take their own photos to upload to the website. Instructional signage has been placed on each post, and a Penn State Brandywine Picture Post website (http://sites.psu.edu/picturepost/) has been created to explain the project and campus objectives in more detail. This project was started by a student as part of her undergraduate summer research experience and will continue to be managed by students in future semesters. With just a half-year of Picture Post photos, it is evident that there are documented changes in the environment because of construction and expected seasonal variations. The Picture Post photos have provided enough data for an initial undergraduate research project with a student analyzing and comparing the variations in the greenness factor of the photos with supplemental temperature and precipitation data. This project will continue to provide opportunities for citizen contributions to the network as well as data for student investigations of the changing campus environment.

  16. Environmental monitoring report: United States Energy Research and Development Administration, Oak Ridge facilities, calendar year 1976

    The Environmental Monitoring Program for the Oak Ridge area includes sampling and analysis of air, water from surface streams, several food products, vegetation, and soil for both radioactive and nonradioactive materials. This report presents a summary of the results of the program for calendar year 1976. Surveillance of radioactivity in the Oak Ridge environs indicates that atmospheric concentrations of radioactivity were not significantly different from other areas in East Tennessee. Concentrations of radioactivity in the Clinch River and in fish collected from the river were less than 8.1 percent of the permissible concentration and intake guides for individuals in the offsite environment. While some radioactivity was released to the environment from plant operations, the concentrations in all of the media sampled were well below established standards. The total body dose to a hypothetical maximum exposed individual at the site boundary was calculated to be 7.2 mrem/yr which is 1.4 percent of the ERDA Manual Chapter 0524 standard. The maximum 50-year dose commitment to the critical organs of an individual from the aquatic food chain was calculated to be 150 millirem to the bone which is 10 percent of the allowable annual standard. The maximum dose commitment to individuals living nearest the site boundary from airborne releases, assuming continuous residence, was 0.4 millirem to the total body and 7.4 millirem to the lung. These doses are 0.08 percent and 0.5 percent, respectively, of the annual standards. The average total body dose to an Oak Ridge resident was estimated to be 0.05 millirem as compared to approximately 100 mrem/yr from natural background radiation; the average dose commitment to the lung of an Oak Ridge resident was 0.7 millirem. The cumulative total body dose to the population within a 50-mile radius of the Oak Ridge facilities resulting from 1976 effluents was calculated to be 5.3 man-rem

    2005-09-01

    A Consortium, designed to assemble leaders in gas hydrates research, has been established at the University of Mississippi's Center for Marine Resources and Environmental Technology, CMRET. The primary objective of the group is to design and emplace a remote monitoring station on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station allows for the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in this relatively new research arena. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. Noteworthy achievements six months into the extended life of this cooperative agreement include: (1) Progress on the vertical line array (VLA) of sensors: Analysis and repair attempts of the VLA used in the deep water deployment during October 2003 have been completed; Definition of an interface protocol for the VLA DATS to the SFO has been established; Design modifications to allow integration of the VLA to the SFO have been made; Experience gained in the deployments of the first VLA is being applied to the design of the next VLAs; One of the two planned new VLAs being modified to serve as an Oceanographic Line Array (OLA).

    This report constitutes Stages 14 and 15 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. Stage 14 was a full one-year project, whereas Stage 15 consisted of a half-year project. The program executed in Stages 14 and 15 consists of the following three parts: - Study of criticality, neutron kinetics and neutron noise in molten salt reactors (MSR) (Stages 14 and 15); - An overview and introduction to fuzzy logics (Stage 14), and an application to two-phase flow identification (Stage 15) - Preparations for and execution of an IAEA-ICTP workshop on Neutron fluctuations, reactor noise and their applications in nuclear reactors (Stage 14)

  6. Using Patterns for Multivariate Monitoring and Feedback Control of Linear Accelerator Performance: Proof-of-Concept Research

    The report discusses preliminary proof-of-concept research for using the Advanced Data Validation and Verification System (ADVVS), a new INEEL software package, to add validation and verification and multivariate feedback control to the operation of non-destructive analysis (NDA) equipment. The software is based on human cognition, the recognition of patterns and changes in patterns in time-related data. The first project applied ADVVS to monitor operations of a selectable energy linear electron accelerator, and showed how the software recognizes in real time any deviations from the optimal tune of the machine. The second project extended the software method to provide model-based multivariate feedback control for the same linear electron accelerator. The projects successfully demonstrated proof-of-concept for the applications and focused attention on the common application of intelligent information processing techniques

    Citizen Science is a fast-growing ecological research tool with proven potential to rapidly produce large datasets. While the fields of astronomy and ornithology demonstrate particularly successful histories of enlisting the public in conducting scientific work, citizen science applications to the field of hydrology have been relatively underutilized. We demonstrate the potential of citizen science for monitoring water quality, particularly in the impervious, urban environment of New York City (NYC) where pollution via stormwater runoff is a leading source of waterway contamination. Through partnerships with HSBC, Earthwatch, and the NYC Water Trail Association, we have trained two citizen science communities to monitor the quality of NYC waterways, testing for a suite of water quality parameters including pH, turbidity, phosphate, nitrate, and Enterococci (an indicator bacteria for the presence of harmful pathogens associated with fecal pollution). We continue to enhance these citizen science programs with two additions to our methodology. First, we designed and produced at-home incubation ovens for Enterococci analysis, and second, we are developing automated photo-imaging for nitrate and phosphate concentrations. These improvements make our work more publicly accessible while maintaining scientific accuracy. We also initiated a volunteer survey assessing the motivations for participation among our citizen scientists. These three endeavors will inform future applications of citizen science for urban hydrological research. Ultimately, the spatiotemporally-rich dataset of waterway quality produced from our citizen science efforts will help advise NYC policy makers about the impacts of green infrastructure and other types of government-led efforts to clean up NYC waterways.

  8. Networking Multiple Autonomous Air and Ocean Vehicles for Oceanographic Research and Monitoring

    McGillivary, P. A.; Borges de Sousa, J.; Rajan, K.

    2013-12-01

    Autonomous underwater and surface vessels (AUVs and ASVs) are coming into wider use as components of oceanographic research, including ocean observing systems. Unmanned airborne vehicles (UAVs) are now available at modest cost, allowing multiple UAVs to be deployed with multiple AUVs and ASVs. For optimal use good communication and coordination among vehicles is essential. We report on the use of multiple AUVs networked in communication with multiple UAVs. The UAVs are augmented by inferential reasoning software developed at MBARI that allows UAVs to recognize oceanographic fronts and change their navigation and control. This in turn allows UAVs to automatically to map frontal features, as well as to direct AUVs and ASVs to proceed to such features and conduct sampling via onboard sensors to provide validation for airborne mapping. ASVs can also act as data nodes for communication between UAVs and AUVs, as well as collecting data from onboard sensors, while AUVs can sample the water column vertically. This allows more accurate estimation of phytoplankton biomass and productivity, and can be used in conjunction with UAV sampling to determine air-sea flux of gases (e.g. CO2, CH4, DMS) affecting carbon budgets and atmospheric composition. In particular we describe tests in July 2013 conducted off Sesimbra, Portugal in conjunction with the Portuguese Navy by the University of Porto and MBARI with the goal of tracking large fish in the upper water column with coordinated air/surface/underwater measurements. A thermal gradient was observed in the infrared by a low flying UAV, which was used to dispatch an AUV to obtain ground truth to demonstrate the event-response capabilities using such autonomous platforms. Additional field studies in the future will facilitate integration of multiple unmanned systems into research vessel operations. The strength of hardware and software tools described in this study is to permit fundamental oceanographic measurements of both ocean

  9. Computerized clinical decision support systems for therapeutic drug monitoring and dosing: A decision-maker-researcher partnership systematic review

    Weise-Kelly Lorraine

    2011-08-01

    Full Text Available Abstract Background Some drugs have a narrow therapeutic range and require monitoring and dose adjustments to optimize their efficacy and safety. Computerized clinical decision support systems (CCDSSs may improve the net benefit of these drugs. The objective of this review was to determine if CCDSSs improve processes of care or patient outcomes for therapeutic drug monitoring and dosing. Methods We conducted a decision-maker-researcher partnership systematic review. Studies from our previous review were included, and new studies were sought until January 2010 in MEDLINE, EMBASE, Evidence-Based Medicine Reviews, and Inspec databases. Randomized controlled trials assessing the effect of a CCDSS on process of care or patient outcomes were selected by pairs of independent reviewers. A study was considered to have a positive effect (i.e., CCDSS showed improvement if at least 50% of the relevant study outcomes were statistically significantly positive. Results Thirty-three randomized controlled trials were identified, assessing the effect of a CCDSS on management of vitamin K antagonists (14, insulin (6, theophylline/aminophylline (4, aminoglycosides (3, digoxin (2, lidocaine (1, or as part of a multifaceted approach (3. Cluster randomization was rarely used (18% and CCDSSs were usually stand-alone systems (76% primarily used by physicians (85%. Overall, 18 of 30 studies (60% showed an improvement in the process of care and 4 of 19 (21% an improvement in patient outcomes. All evaluable studies assessing insulin dosing for glycaemic control showed an improvement. In meta-analysis, CCDSSs for vitamin K antagonist dosing significantly improved time in therapeutic range. Conclusions CCDSSs have potential for improving process of care for therapeutic drug monitoring and dosing, specifically insulin and vitamin K antagonist dosing. However, studies were small and generally of modest quality, and effects on patient outcomes were uncertain, with no convincing

  10. Self-monitoring surveillance system for prestressing tendons. Phase I small business innovation research

    Assured safety and operational reliability of post-tensioned concrete components of nuclear power plants are of great significance to the public, electric utilities, and regulatory agencies. Prestressing tendons provide principal reinforcement for containment and other structures. In this phase of the research effort, the feasibility of developing a passive surveillance system for identification of ruptures in tendon wires was evaluated and verified. The concept offers high potential for greatly increasing effectiveness of presently-utilized periodic tendon condition surveillance programs. A one-tenth scale ring model of the Palo Verde nuclear containment structure was built inside the Structural Laboratory. Dynamic scaling (similitude) relationships were used to relate measured sensor responses recorded during controlled wire breakages to the expected prototype containment tendon response. Strong and recognizable signatures were detected by the accelerometers used. It was concluded that the unbonded prestressing tendons provide an excellent path for transmission of stress waves resulting from wire breaks. Accelerometers placed directly on the bearing plates at the ends of tendons recorded high-intensity waveforms. Accelerometers placed elsewhere on concrete surfaces of the containment model revealed substantial attenuation and reduced intensities of captured waveforms. Locations of wire breaks could be determined accurately through measurement of differences in arrival times of the signal at the sensors. Pattern recognition systems to be utilized in conjunction with the proposed concept will provide a basis for an integrated and automated tool for identification of wire breaks

  11. Research on self-powered detectors for gamma-ray monitoring

    Self-powered neutron detectors are used extensively in power reactors both for flux mapping and for power control and over-power protection, because of their small size, ruggedness and simplicity. But they have a few disadvantages such as high burn-up rate and background signal produced by the gamma-rays from the reactor itself. In order to overcome these disadvantages and to achieve a better understanding of gamma-ray effects of self-powered detectors, a new type of self-powered detectors was designed and fabricated by the author, and experiments have been carried out in the 10kCi sup(60)Co gamma irradiation facility in Korea Advanced Energy Research Institute. The configuration of the new type detectors is not of coaxial type but of paralled plate in order to obtain directional effects of gamma-ray incidence. Detector materials and dimensions are so chosen that the output current signal is large enough to be detected using some commercial measuring divice even at low dose rate and the contribution of the lead cable to the totel signal is negligibly small. The results are 1) sensitivity is depended primarily on the materials of the insulator, 2) output signal has a good linearity to gamma dose rate, 3) response of detectors is prompt, but not perfect, 4) critical thickness for satusation of the output current is thinner than the range of photoelectron in the materials.

  12. Yucca Mountain program summary of research, site monitoring and technical review activities (January 1987--June 1988)

    Although studies of orbital mechanics provide speculative notions of future climatic trends, they cannot predict how these trends will manifest themselves in the immediate area around Yucca Mountain. The generally accepted approach to this question is to consider the climatic variations that have occurred during the last 10,000 years, and use these as a guide to the likely range of future variation in climate. However, because climatic studies around the world indicate that we are potentially on the verge of another ice age, we should also consider the conditions that predominated during the Pleistocene. The specific aim of this project is to derive the climatic history of Yucca Mountain during the last 20,000 years from the vegetation history. By integrating data obtained from pollen records, woodrat dens (middens), and tree-ring sequences from the Nevada Test Site (NTS) area, a regional climatic record is being generated that can be correlated to data obtained at Yucca Mountain to formulate a local climatic sequence there. This will then be used to determine the magnitude and frequency of climatic variation that have occurred during that time at Yucca Mountain. These data can then be used by other researchers to provide estimates of rainfall, recharge and soil chemical changes for modeling the past hydrology of Yucca Mountain

    A Consortium, designed to assemble leaders in gas hydrates research, has been established at the University of Mississippi's Center for Marine Resources and Environmental Technology, CMRET. The primary objective of the group is to design and emplace a remote monitoring station on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station allows for the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in this relatively new research arena. Complementary expertise, both scientific and technical, has been assembled to innovate research methods and construct necessary instrumentation.

    2012-07-01

    Two types of wireless transmission systems using ultra low frequency (8.5 kHz) were developed and used in the Callovo-Oxfordian argillites layer in the Meuse / Haute-Marne Underground Research Laboratory (CMHM URL) in France. Short-range and mid-range transmission antennas received data transmitted from 25 m to 50 m away. From the results of two series of tests, it is clear that transmission is practical when the received voltage is larger than the received noise. However, it is also clear that wireless transmission in the CMHM URL gallery is affected by the electromagnetic noise level and steel components, and the maximum transmission distance depends on the S/N ratio. The mid-range transmission antenna achieved a transmission distance of 240 m in the surface test, where the electromagnetic noise level was small and there was no environmental attenuation. The short-range transmission antenna achieved a transmission distance of 25 m in the surface test and in the CMHM URL gallery. As the clay layer of the CMHM URL had little effect on the attenuation of the electromagnetic field, transmission over 200 m might be possible in the CMHM URL when the electromagnetic noise level is small enough and there are no significant factors enhancing attenuation. But in reality, the possible transmission distance was around 50 m. In order to show the transmitter's ability, it is preferable to keep some distance between steel components and the transmitter. The most effective way to use this transmitter is to put it in a borehole drilled from a gallery to outside of a gallery around 10 m length. In this way, it might be possible to avoid almost of all the influence of steel components. For the position of receiver, the recommendation is the same as for the transmitter. That is, place the receiver where the incoming signal from the transmitter suffers little attenuation from steel components. Therefore, the option of implementing a receiving antenna in a borehole is required

  16. Developing a Model using High School Students for Restoring, Monitoring and Conducting Research in Fresh Water Wetlands

    Blueford, J. R.

    2010-12-01

    Tule Ponds at Tyson Lagoon in eastern San Francisco Bay is one of the largest sag ponds created by the Hayward Fault that has not been destroyed by urbanization. In the 1990’s Alameda County Flood Control and Water Conservation District designed a constructed wetland to naturally filter stormwater before it entered Tyson Lagoon on its way to the San Francisco Bay. The Math Science Nucleus, a non profit organization, manages the facility that incorporates high school students through community service, service learning, and research. Students do a variety of tasks from landscaping to scientific monitoring. Through contracts and grants, we create different levels of competency that the students can participate. Engineers and scientists from the two agencies involved, create tasks that are needed to be complete for successful restoration. Every year the students work on different components of restoration. A group of select student interns (usually juniors and seniors) collects and records the data during the year. Some of these students are part of a paid internship to insure their regular attendance. Every year the students compile and discuss with scientists from the Math Science Nucleus what the data set might mean and how problems can be improved. The data collected helps determine other longer term projects. This presentation will go over the journey of the last 10 years to this very successful program and will outline the steps necessary to maintain a restoration project. It will also outline the different groups that do larger projects (scouts) and liaisons with schools that allow teachers to assign projects at our facility. The validity of the data obtained by students and how we standardize our data collection from soil analysis, water chemistry, monitoring faults, and biological observations will be discussed. This joint agency model of cooperation to provide high school students with a real research opportunity has benefits that allow the program to

  17. Environmental monitoring at major U.S. Energy Research and Development Administration contractor sites: calendar year 1976. Volume 2

    The purpose of this compilation is to present, in a central reference document, all of the individual annual reports summarizing the results of the environmental monitoring programs conducted at each of the Energy Research and Development Administration (ERDA) sites having a potential for environmental impact or which release a significant quantity of radioactivity or nonradioactive pollutants. Data on the levels of radioactivity and nonradioactive pollutants in effluents and the environs at each site are given, and effluent and environmental measurements and sampling results are evaluated in relation to the appropriate standards for environmental protection, including estimates of potential radiation exposures offsite. It is noteworthy that, in most cases, the potential offsite exposures are so low they cannot be determined by direct measurement methods but must be estimated by calculational techniques. All potential offsite exposures to members of the public from routine effluent releases in 1976 were less than 5 mrem/yr (i.e., less than one percent of the established radiation protection guidelines for exposure of the public). Additionally, the estimated collective man-rem dose potential to all members of the public within an 80 Km radius at all ERDA sites is less than .02 percent of the estimated man-rem dose due to natural and background environmental radiation

    The purpose of this compilation is to present, in a central reference document, all of the individual annual reports summarizing the results of the environmental monitoring programs conducted at each of the Energy Research and Development Administration (ERDA) sites having a potential for environmental impact or which release a significant quantity of radioactivity or nonradioactive pollutants. Data on the levels of radioactivity and nonradioactive pollutants in effluents and the environs at each site are given, and effluent and environmental measurements and sampling results are evaluated in relation to the appropriate standards for environmental protection, including estimates of potential radiation exposures offsite. It is noteworthy that, in most cases, the potential offsite exposures are so low they cannot be determined by direct measurement methods but must be estimated by calculational techniques. All potential offsite exposures to members of the public from routine effluent releases in 1976 were less than 5 mrem/yr (i.e., less than one percent of the established radiation protection guidelines for exposure of the public). Additionally, the estimated collective man-rem dose potential to all members of the public within an 80 Km radius at all ERDA sites is less than .02 percent of the estimated man-rem dose due to natural and background environmental radiation.

    Recently, the Institute for Marine Science of the Italian Research Council ISMAR-CNR has undertaken a series of actions to incorporate oceanography in education: among these, the project "SeaCleaner" that has been developed together with a local Secondary School (Istituto di Istruzione Superiore Capellini-Sauro) and the Ligurian Cluster for Marine Technologies (DLTM) [1]. Seven students, engaged within the national Programme "work-related learning"[2], have worked side-by-side with ISMAR-CNR researchers, investigating on the problem of debris accumulation on beaches, and understanding the damage that this issue causes to marine environments and ecosystems. This problem has recently become a challenging research subject for an increasing number of oceanographers and, in general, for environmental researchers coming from the Mediterranean areas [3, 4, 5], other European Seas [6] and Oceans [7, 8]. Data collected during repeated surveys (seasonally) in the same beach stretch, over several years, allow calculating debris accumulation rates and flow intensities. Application of current models gives additional information on debris dispersal and origin, but we shouldn't forget that, generally, relevance of acquired data is determined by the accuracy and standardization of the procedure. In this context, students have previously searched for literature sources and summarized the most important issues, among these: few data that are often collected during small ranges of time and usually a low number of available researchers for carrying out such a time-consuming survey in the field. In a initial part of the project, several trial surveys have been performed on different beaches in La Spezia province, in order to understand how to elaborate possible strategies to speed up and standardize the procedure. Developing an application for Android system (downloadable on any compatible mobile device such as smartphones, tablets, etc.) has been considered as a good solution since it

  20. On-line condition monitoring systems for high voltage circuit breakers : a collaborative research project 1997-2001

    A three year field project was initiated to review and evaluate the state of the art in on-line conditioning monitoring technology for a high voltage (240 kV SF6) circuit breaker located at Dorsey Converter Station. The ELF breaker is a three independent pole design which allows for three separate monitoring systems. This project involved the installation of a different type of monitoring system on each phase and incorporated many types of transducers. Each monitoring system measured the same basic parameters including contact travel, 'a' and 'b' auxiliary contacts, phase currents, coil currents, heater and pump current, plus SF6/CF4 pressure and temperature. Over the entire monitoring period the breaker was operated over 700 times at rated voltage and an additional 300 times during maintenance. Temperature conditions ranged from -35 to +30 degrees C. The use of on-line monitoring provided many valuable results and enhanced the knowledge base for the apparatus under the test. It was determined that on-line monitoring of HV circuit breakers has potential, but installation has to be considered carefully. Monitoring systems can offer improvement in the understanding of how circuit breakers work and provide input into RCM programs. However, monitoring systems themselves are subject to failure and require maintenance and attention. 2 refs., 2 tabs., 7 figs.

    In the Mediterranean countries, forest fires are common and must be considered as an ecological factor, but changes in land use, especially in the last five decades have provoked a modification in their natural regime. Moreover, post-fire management can have an additional impact on the ecosystem; in some cases, even more severe than the fire. Salvage logging is a traditional management in most fire-affected areas. In some cases, the way of doing it, using heavy machinery, and the vulnerability of soils to erosion and degradation make this management potentially very agresive to soil, and therefore to the ecosystem. Very little research has been done to study how this treatment could affect soil health. In this research we show 2 years of monitoring of some soil properties in an area affected by a forest fire, where some months later this treatment was applied. The study area is located in 'Sierra de Mariola Natural Park' in Alcoi, Alicante (E Spain). A big forest fire (>500 has) occurred in July 2012. The forest is composed mainly of Pinus halepensis trees with an understory of typical Mediterranean shrubs species such as Quercus coccifera, Rosmarinus officinalis, Thymus vulgaris, Brachypodium retusum, etc. Soil is classified as a Typic Xerorthent (Soil Survey Staff, 2014) developed over marls. In February 2013, salvage logging (SL) treatment consisting in a complete extraction of the burned wood using heavy machinery was applied in a part of the affected forest. Plots for monitoring this effect were installed in this area and in a similar nearby area where no treatment was done, and then used as control (C) for comparison. Soil samplings were done immediately after treatment and every 6 months. Some soil properties were analysed, including soil organic matter (SOM) content, basal soil respiration (BSR), microbial biomass carbon (MBC), bulk density (BD), soil water repellency (SWR), aggregate stability (AS), field capacity, nitrogen, etc. After two years of

    The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research that shared the need for a way to conduct investigations of gas hydrates and their stability zone in the Gulf of Mexico in situ on a more-or-less continuous basis. The primary objective of the group is to design and emplace a remote monitoring station or sea floor observatory (SFO) on the sea floor in the northern Gulf of Mexico, in an area where gas hydrates are known to be present at, or just below, the sea floor and to discover the configuration and composition of the subsurface pathways or 'plumbing' through which fluids migrate into and out of the hydrate stability zone (HSZ) to the sediment-water interface. Monitoring changes in this zone and linking them to coincident and perhaps consequent events at the seafloor and within the water column is the eventual goal of the Consortium. This mission includes investigations of the physical, chemical and biological components of the gas hydrate stability zone - the sea-floor/sediment-water interface, the near-sea-floor water column, and the shallow subsurface sediments. The eventual goal is to monitor changes in the hydrate stability zone over time. Establishment of the Consortium succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among those involved in gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative methods and construct necessary instrumentation. Following extensive investigation into candidate sites, Mississippi Canyon 118 (MC118) was chosen by consensus of the Consortium at their fall, 2004, meeting as the site most likely to satisfy all criteria established by the group. Much of the preliminary work preceding the establishment of the site - sensor development and testing, geophysical surveys, and laboratory studies - has been reported in

  6. Monitoring the source monitoring.

    The hypothesis that the retrieval of correct source memory cues, those leading to a correct source attribution, increases confidence, whereas the retrieval of incorrect source memory cues, those leading to a source misattribution, decreases confidence was tested. Four predictions were derived from this hypothesis: (1) confidence should be higher for correct than incorrect source attribution except; (2) when no source cues are retrieved; (3) only the source misattributions inferred from the retrieval of incorrect source cues will be rated with low confidence; and (4) the number of source cues retrieved, either correct or incorrect, will affect the confidence in the source attributions. To test these predictions, participants read two narratives from two witnesses to a bank robbery, a customer and a teller. Then, participants completed a source monitoring test with four alternatives, customer, teller, both, or neither, and rated their confidence in their source attribution. Results supported the first three predictions, but they also suggested that the number of correct source monitoring cues retrieved did not play a role in the monitoring of the accuracy of the source attributions. Attributions made from the recovery of incorrect source cues could be tagged as dubious or uncertain, thus leading to lowered confidence irrespective of the number of incorrect source cues or whether another correct source cue was also recovered. This research has potential applications for eyewitness memory because it shows that confidence can be an indicator of the accuracy of a source attribution. PMID:23553316

  9. Groundwater Monitoring and Control Before Decommissioning of the Research Reactor VVR-S from Magurele-Bucharest

    Treatment Plant) - the 300 m3 tanks and the Spent Filters Storage (SFS). At south of this area, on the leaking direction of the underground water layer, in the drillings F1, F2, F3, F18 and at east, in F6, F7, the natural Uranium values are within the background for the underground-water. Distribution of Radon For the Radon determination with RAD 7 equipment, water samples were taken from the same piezo-metrical drilling, 2 or 4 times during of six months period, and then, the average contents were calculated, which varied between 0,35 - 2,1 Bq/l. The values higher than 1,1 -1,2 Bq/l were detected in the water taken from the drillings located in the northern part (F10, F11) and in the eastern part (F6, F8) of the Institute fences (around of the radioactive waste storage facilities). The concentrations of 0,3 - 0,5 Bq/l are in the underground-water layer 'intercepted' by the piezo-metrical drillings (F1, F2, F3) located near the Nuclear Reactor. Concentration of heavy metals: 0.04-0.08 mg/l Pb in F5, F14, F7, F8 exceeding MCA-Maximum Admissible Concentration (0.01 mg/l) for Pb, and for Zn in F5, F7, F8, F14 are 0.2-0.5 mg/l situated under MCA , and 0.18 mg/l in F18, in accordance with tendency of decreasing of concentration of contaminants. After 50 years of deploying nuclear activities on the site the underground water quality is in very good condition. Taking into consideration the direction of the underground water flow, it results that, only in the area of underground pipe, around of the research reactor and radioactive waste treatment plant, the quality of water is influenced, and remediation actions are not necessary. Based on measurements executed in F18, the water quality is the same with any other part of the region. During the decommissioning of the Research Reactor, the samples from 18 drillings will be analysed monthly, and the contents of the heavy metals, Pb and Zn, will be monitored carefully, together with all the factors: air, soil, vegetation, subsoil

    The Material Protection, Control and Accounting (MPC&A) Operations Monitoring (MOM) systems handling at the International Intergovernmental Organization - Joint Institute for Nuclear Research (JINR) is described in this paper. Category I nuclear material (plutonium and uranium) is used in JINR research reactors, facilities and for scientific and research activities. A monitoring system (MOM) was installed at JINR in April 2003. The system design was based on a vulnerability analysis, which took into account the specifics of the Institute. The design and installation of the MOM system was a collaborative effort between JINR, Brookhaven National Laboratory (BNL) and the U.S. Department of Energy (DOE). Financial support was provided by DOE through BNL. The installed MOM system provides facility management with additional assurance that operations involving nuclear material (NM) are correctly followed by the facility personnel. The MOM system also provides additional confidence that the MPC&A systems continue to perform effectively.

    Flux stations have been widely used to monitor release and uptake rates of CO2, CH4, H2O and other gases from various ecosystems for climate research for over 30 years. The stations provide accurate and continuous measurements of gas exchange at time scales ranging from 15 or 30 minutes to multiple years, and at spatial scales ranging from thousands m2 to multiple km2, depending on the measurement height. The stations can nearly instantaneously detect rapid changes in gas release due to weather or man-triggered events (pressure changes, ice breakage and melts, ebullition events, etc.). They can also detect slow changes related to seasonal dynamics and man-triggered processes (seasonal freeze and thaw, long-term permafrost degradation, etc.). From 1980s to mid-2000s, station configuration, data collection and processing were highly-customized, site-specific and greatly dependent on "school-of-thought" practiced by a particular researcher. In the past 3-5 years, due to significant efforts of global and regional flux networks and technological developments, the methodology became fairly standardized. Majority of current stations compute gas emission and uptake rates using eddy covariance method, as one of the most direct micrometeorological techniques. Over 600 such flux stations operate in over 120 countries, using permanent and mobile towers or moving platforms (e.g., automobiles, helicopters, airplanes, ships, etc.). With increasing atmospheric temperatures in the Arctic likely resulting in a higher rate of permafrost degradation, measurements of gas exchange dynamics become particularly important. The permafrost regions store a significant amount of organic materials under anaerobic conditions, leading to large CH4 production and accumulation in the upper layers of bedrock, soil and ice. These regions may become a significant potential source of global CH4 release under a warming climate over the following decades and centuries. Present measurements of CH4 release

  15. Methodology to monitor and diagnostic vibrations of the motor-pumps used in the primary cooling system of IEAR-1 nuclear research reactor

    The objectives of this study are to establish a strategy to monitor and diagnose vibrations of the motor pumps used in the primary reactor cooling system of the IEA-R1 nuclear research reactor, to verify the possibility of using the existing installed monitoring vibration system and to implement such strategy in a continuous way. Four types of mechanical problems were considered: unbalancing, misalignment, gaps and faults in bearings. An adequate set of analysis tools, well established by the industry, was selected. These are: global measurements of vibration, velocity spectrum and acceleration envelope spectrum. Three sources of data and information were used; the data measured from the primary pumps, experimental results obtained with a Spectra Quest machine used to simulate mechanical defects and data from the literature. The results show that, for the specific case of the motor-pumps of IEA-R1 nuclear research reactor, although the technique using the envelope of acceleration, which is not available in the current system used to monitor the vibration of the motor pumps, is the one with best performance, the other techniques available in the system are sufficient to monitor the four types of mechanical problems mentioned. The proposed strategy is shown and detailed in this work. (author)

  16. Erosion research with a digital camera: the structure from motion method used in gully monitoring - field experiments from southern Morocco

    Kaiser, Andreas; Rock, Gilles; Neugirg, Fabian; Müller, Christoph; Ries, Johannes

    2014-05-01

    From a geoscientific view arid or semiarid landscapes are often associated with soil degrading erosion processes and thus active geomorphology. In this regard gully incision represents one of the most important influences on surface dynamics. Established approaches to monitor and quantify soil loss require costly and labor-intensive measuring methods: terrestrial or airborne LiDAR scans to create digital elevation models and unmanned airborne vehicles for image acquisition provide adequate tools for geomorphological surveying. Despite their ever advancing abilities, they are finite with their applicability in detailed recordings of complex surfaces. Especially undercuttings and plunge pools in the headcut area of gully systems are invisible or cause shadowing effects. The presented work aims to apply and advance an adequate tool to avoid the above mentioned obstacles and weaknesses of the established methods. The emerging structure from motion-based high resolution 3D-visualisation not only proved to be useful in gully erosion. Moreover, it provides a solid ground for additional applications in geosciences such as surface roughness measurements, quantification of gravitational mass movements or capturing stream connectivity. During field campaigns in semiarid southern Morocco a commercial DSLR camera was used, to produce images that served as input data for software based point cloud and mesh generation. Thus, complex land surfaces could be reconstructed entirely in high resolution by photographing the object from different perspectives. In different scales the resulting 3D-mesh represents a holistic reconstruction of the actual shape complexity with its limits set only by computing capacity. Analysis and visualization of time series of different erosion-related events illustrate the additional benefit of the method. It opens new perspectives on process understanding that can be exploited by open source and commercial software. Results depicted a soil loss of 5

  17. Application Of GIS-Technologies And RS-Data For Research And Monitoring Of Water Reservoirs And Other Objects

    -technologies and RS-data was created in Astronomical institute. It is well-known, that in the Central Asian region there is a problem of joint rational and effective use of water resources. In the center of this problem there are such important objects as water basins. Therefore studying, monitoring and creation of digital three-dimensional models of water basins and reservoirs with application of GIS-technologies and RS is the important and actual task. From the methodological point of view the process of creation of such projects can be divided into the following stages: 1. Allocation of water basins that would be interesting for the end users, determination of their coordinates, general characteristics and features.; 2. Search and receive the topographical maps, space images, radar data and other accessible information about the chosen objects.; 3. Preliminary processing of images, geographical binding of all data in one uniform system of coordinates.; 4. Creation of the basic GIS-project with the complete set of thematic layers and legends to the chosen objects.; 5. Development of algorithms and techniques of creation of three-dimensional models and estimations of condition of lakes and water basins using radar data, space images for different dates and topographic maps. 6. Final adjustment of the specialized GIS-project with the filled layers and data on objects of research for the analysis and forecasting of their condition for the next years and updating of layers of the GIS-project. Application of such GIS-project with use of RS data will allow to control conditions of water objects, quantitatively estimate the stocks of water resources, plan their rational usage, develop models of forecasting of emergencies (landslides and avalanches, breaks of dams, danger changes of natural reservoirs), and also many other things.

  19. Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods. Stage 10. Final Report

    This report constitutes Stage 10 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. The program executed in Stage 10 consists of three parts and the work performed in each part is summarized below. A so-called 2-D 2-group neutron noise simulator was previously developed at the Department of Reactor Physics. This simulator is able to calculate the space-dependence of the neutron noise induced by localised or spatially-distributed absorbers of variable strength or by vibrating absorbers. These calculations are performed in the 2-group diffusion approximation and can treat an arbitrary heterogeneous 2-D system. The goal of the present investigation is to use the simulator for unfolding purposes, i.e. to reconstruct the noise source from the detector readings. This task is particularly challenging since the number of detectors available in a commercial PWR can be very low. In this study, five detectors are assumed to be present and evenly distributed in the core. Furthermore, only localised absorbers of variable strength are considered as perturbations. Numerical simulations were first carried out to verify that the space-dependent local and global components of the neutron noise were overwhelmingly large compared to the point-kinetic term of the neutron noise whose spatial structure does not depend on the position of the perturbation. The significance of the space-dependent global component is that its relaxation length is large enough, so that several neutron detectors can monitor it. Therefore, the neutron noise induced at the position of the detectors is itself a function of the position of the perturbation. Unfolding procedures could thus be considered. Prior to performing any unfolding, the type of the noise source has to be determined, since the algorithms developed in this report are based on the assumption of an absorber of variable strength. Such a noise source can also be

  20. Research project implementation of a risk-based performance monitoring system for nuclear power plants: Phase II - Type-D indicators. Final report

    This study has established the basis for incorporating a meaningful set of Type-D performance indicators into an overall performance monitoring system based on a PSA framework. The relationships developed as part of this study enable various organizational, maintenance, and operational influences, that are manifested through key events that can be identified and reported at a plant, to be accounted for in terms of their impacts on safety. The relationships and the capability they pose are significant new and unique developments. The relationships require that plant-specific data on the key performance indicators be acquired and analyzed. This, in turn, necessitates that a regular and systematic supplementary data collection program be implemented. Hence, it is recommended here that such a data program be developed and undertaken, specifically within the context of an overall PSA-based safety monitoring system. Plant licensees should be responsible for the supplemental data collection effort; however, the data collection requirements should not pose an undue burden on the licensees. To the extent possible, the data collection program should be coordinated, and possibly integrated, with existing licensee data collection and event reporting efforts. This study was undertaken to help verify whether or not it would be feasible to proceed with a PSA-based performance monitoring program. Research performed for Part-1 investigation has resulted in the development of a systematic and structured approach for monitoring safety performance based on all types of plant events. The Type-D relationships were earlier identified as a key element of the proposed performance monitoring system, and if it would be discovered that the Type-D relationships could not be practically developed and implemented, then it would have lead to the recognition that the performance monitoring system might have little practical value. On the other hand, if the Type-D relationships could be efficiently

  2. Development of an artificial neural network for monitoring and diagnosis of sensor fault and detection in the IEA-R1 research reactor at IPEN

    The increasing demand on quality in production processes has encouraged the development of several studies on Monitoring and Diagnosis Systems in industrial plant, where the interruption of the production due to some unexpected change can bring risk to the operator's security besides provoking economic losses, increasing the costs to repair some damaged equipment. Because of these two points, the economic losses and the operator's security, it becomes necessary to implement Monitoring and Diagnosis Systems. In this work, a Monitoring and Diagnosis Systems was developed based on the Artificial Neural Networks methodology. This methodology was applied to the IEA-R1 research reactor at IPEN. The development of this system was divided in three stages: the first was dedicated to monitoring, the second to the detection and the third to diagnosis of failures. In the first stage, several Artificial Neural Networks were trained to monitor the temperature variables, nuclear power and dose rate. Two databases were used: one with data generated by a theoretical model and another one with data to a typical week of operation of the IEA-R1 reactor. In the second stage, the neural networks used to monitor the variables was tested with a fault database. The faults were inserted artificially in the sensors signals. As the value of the maximum calibration error for special thermocouples is ±0,5 deg C, it had been inserted faults of ± 10 C in the sensors for the reading of the variables T3 and T4. In the third stage a Fuzzy System was developed to carry out the faults diagnosis, where were considered three conditions: a normal condition, a fault of 10 C , and a fault of + 10 C . This system will indicate which thermocouple is faulty. (author)

    Full Text Available Aiming at the key technical problems encountered by domestic and foreign scholars in building the real-time monitoring system for the micro leak of three-dimensional pipe networks, the paper classifies the problems into three aspects: 1 in the extraction of fault signal frequency, how to avoid the effect of the mixed echo stack and improve the delay estimation accuracy of the correlation; 2 in network bifurcation structure, how to discern the signal propagation path, and how to locate the leak source; 3 under the uncertainly delay in transmitting and receiving information data, how to ensure the time synchronization accuracy of the real-time monitoring system for the three-dimensional pipe network leakage. Through the comparison of the monitoring technologies for the pipe network leakage at home and abroad, it shows that the acoustic emission sensor network based three-dimensional pipeline leak real-time monitoring has great advantages in detecting the weak leakage of flammable and explosive gas/liquid transportation pipelines.

    2013-04-01

    Formation of ettringite and gypsum from sulfate attack together with carbonation and chloride ingress have been considered as the most serious deterioration mechanisms of concrete structures. Although Electrical Resistance Sensors and Fibre Optic Chemical Sensors could be used to monitoring the latter two mechanisms in situ, currently there is no system for monitoring the deterioration mechanisms of sulfate attack and hence still needs to be developed. In this paper, a preliminary study was carried out to investigate the feasibility of monitoring the sulfate attack with optical fibre Raman spectroscopy through characterizing the ettringite and gypsum formed in deteriorated cementitious materials under an `optical fibre excitation + spectroscopy objective collection' configuration. Bench-mounted Raman spectroscopy analysis was also used to validate the spectrum obtained from the fibre-objective configuration. The results showed that the expected Raman bands of ettringite and gypsum in the sulfate attacked cement paste have been clearly identified by the optical fibre Raman spectroscopy and are in good agreement with those identified from bench-mounted Raman spectroscopy. Therefore, based on these preliminary results, there is a good potential of developing an optical fibre Raman spectroscopy-based system for monitoring the deterioration mechanisms of concrete subjected to the sulfate attack in the future.

  10. Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods. Stage 8. Final report

    This report constitutes Stage 8 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. A brief proposal for the continuation of this program in stage 9 is also given at the end of the report. The program executed in Stage 8 consists of three parts and the work performed in each part is summarized below. In Stage 7, an anomaly localisation algorithm was presented and applied to the Forsmark-1 channel instability event. This investigation was carried out with a set of static data that were typical of a generic BWR model, since no data except the Local Power Range Monitors (LPRMs) time signals recorded during the instability event were made accessible to us at that time. In the present Stage, these static data were obtained from Vattenfall Fuel AB, who used the SIMULATE-3 code. The first Section of this report is thus devoted to this anomaly localisation but this time with a relevant set of data, both regarding the static core conditions and regarding the LPRMs time signals. The noise source pointed out by the localisation algorithm was once again found to be very close to an unseated fuel assembly discovered during the fuel outage following the instability event. The localisation procedure relies in fact on the prior calculation of the reactor transfer function, carried out via the neutron noise simulator first presented in Stage 6 and later improved in Stage 7. The neutron noise simulator was also improved in this Stage. More precisely, a 2-D 2- group static core simulator was developed in order to calculate the static flux and the associated eigenvalue with a spatial discretization scheme compatible with the one in use in the neutron noise simulator, i.e. finite differences. It has generally been assumed that the Decay Ratio (DR), a parameter characterizing the stability of BWRs, is a space-independent parameter of the reactor, i.e. it is independent of which LPRM is used in the core to

  13. Herd monitoring to optimise fertility in the dairy cow: making the most of herd records, metabolic profiling and ultrasonography (research into practice).

    Smith, R F; Oultram, J; Dobson, H

    2014-05-01

    Fertility performance is intrinsically linked to the quality of the animal environment, overall management and nutrition. This review describes the use of dairy herd records, metabolic profiles and ultrasonographic findings at veterinary fertility examinations to monitor and manage dairy herd fertility. After calving, a cow has to overcome a series of physiological hurdles before establishing a pregnancy. The selection of timely key performance indicators (KPIs) that monitor specific events in the postpartum and service periods is vital to correctly identify problems and their potential causes that hopefully can be rectified. Cumulative sum charts are the timeliest monitors of efficiency of detection of oestrus, insemination outcome and relationship between postpartum events and fertility, with the point of inflection indicating when a change took place. Other KPIs use data from specific cohorts, adding an inherent delay to when change is indicated. Metabolic profiles and milk constituent data allow monitoring of nutritional adequacy and developments to offer new possibilities of on-farm systems for regular measurements of milk constituents (including progesterone) and energy status. Examination of the reproductive tract can be used to indicate individual and herd fertility status but the currently available detail is under used. Recent advances in ultrasonography can improve the diagnosis of reproductive tract pathophysiology still further but the clinical use of these methods in veterinary practice needs further evaluation. Development of new KPIs to exploit research findings are needed to ensure this knowledge is used to improve on-farm performance. PMID:24709163

  14. High temperature on-line monitoring of water chemistry and corrosion control in water cooled power reactors. Report of a co-ordinated research project 1995-1999

    This report documents the results of the Co-ordinated Research Project (CRP) on High Temperature On-line Monitoring of Water Chemistry and Corrosion in Water Cooled Power Reactors (1995-1999). This report attempts to provide both an overview of the state of the art with regard to on-line monitoring of water chemistry and corrosion in operating reactors, and technical details of the important contributions made by programme participants to the development and qualification of new monitoring techniques. The WACOL CRP is a follow-up to the WACOLIN (Investigations on Water Chemistry Control and Coolant Interaction with Fuel and Primary Circuit Materials in Water Cooled Power Reactors) CRP conducted by the IAEA from 1986 to 1991. The WACOLIN CRP, which described chemistry, corrosion and activity-transport aspects, clearly showed the influence of water chemistry on corrosion of both fuel and reactor primary-circuit components, as well as on radiation fields. It was concluded that there was a fundamental need to monitor water-chemistry parameters in real time, reliably and accurately. The objectives of the WACOL CRP were to establish recommendations for the development, qualification and plant implementation of methods and equipment for on-line monitoring of water chemistry and corrosion. Chief investigators from 18 organizations representing 15 countries provided a variety of contributions aimed at introducing proven monitoring techniques into plants on a regular basis and filling the gaps between plant operator needs and available monitoring techniques. The CRP firmly demonstrated that in situ monitoring is able to provide additional and valuable information to plant operators, e.g. ECP, high temperature pH and conductivity. Such data can be obtained promptly, i.e. in real time and with a high degree of accuracy. Reliable techniques and sensor devices are available which enable plant operators to obtain additional information on the response of structural materials in

  19. Remote Sensing-based Drought Monitoring Approach and Research Progress%以遥感为基础的干旱监测方法研究进展

    周磊; 武建军; 张洁

    2015-01-01

    Drought is a serious natural disaster. It is doing increasingly damage to the human environment as the drought events occur more frequently. Real-time and effective drought monitoring is an effective means to reduce the losses caused by drought. Since the beginning of 20th century, a lot of drought indices have been de-veloped for monitoring the occurrence and variation of drought. Drought is a complex natural disaster. Howev-er, each drought index has its own advantages and weaknesses in drought monitoring. Almost all the drought indices are based on specific geographical and temporal scales;it is difficult to spread its applicability all over the world. Because of the meteorological drought indices using discrete, point-based meteorological measure-ments collected at weather station locations, the results have restricted level of spatial precision for monitoring drought patterns. Remote sensing technology provides alternative data for operational drought monitoring, with advanced temporal and spatial characteristics. However, additional information still needs to be incorpo-rated so as to thoroughly explain the anomaly in vegetation caused by drought. Besides, to achieve a more ac-curate description of drought characteristics, drought intensity differences caused by vegetation type, tempera-ture, elevation, manmade irrigation, and other factors under the same water condition must be considered. Therefore, effective drought monitoring indicator should both reflect soil moisture, vegetation condition and take into account vegetation type, temperature, and man-made factors leading to regional drought differences. Aiming at the problem mentioned above, the satellite based drought indices, and integrated meteorological and remote sensed drought indices was reviewed in our research. Firstly, this paper summarized the widely used drought monitoring models which were based on remote sensing data. The remote sensing drought monitoring approach was summarized by dividing

    be considered. Therefore, effective drought monitoring indicator should both reflect soil moisture, vegetation condition and take into account vegetation type, temperature, and man-made factors leading to regional drought differences. Aiming at the problem mentioned above, the satellite based drought indices, and integrated meteorological and remote sensed drought indices was reviewed in our research. Firstly, this paper summarized the widely used drought monitoring models which were based on remote sensing data. The remote sensing drought monitoring approach was summarized by dividing it into four classes i.e. vegetation condition monitoring methods, micro-wave soil moisture monitoring methods, thermal infrared remote sensing monitoring methods and indices based on energy balance theory. The characteristics, application conditions and problems of the monitoring method which were based on remote sensing data and multi-source data (meteorological data, remote sensing data and biophysical data) were deeply analyzed. Then, the future development direction of drought monitor-ing model was studied and discussed by concluding comprehensive drought monitoring model which was based on multi-source data. Integrated multi-source data to construct comprehensive drought monitoring mod-el was pointed out as a new approach to solve complex problems of drought monitoring. It can solve the incon-sistency problems of space and temporal resolution from different data types. But the present study concluded that research on this area is still in the experimental and exploratory stage and need further improvement and development.

  1. Research and Development of Information and Communication Technology-based Home Blood Pressure Monitoring from Morning to Nocturnal Hypertension.

    Asians have specific characteristics of hypertension (HTN) and its relationship with cardiovascular disease. The morning surge in blood pressure (BP) in Asians is more extended, and the association slope between higher BP and the risk for cardiovascular events is steeper in this population than in whites. Thus, 24-hour BP control including at night and in the morning is especially important for Asian patients with HTN. There are 3 components of "perfect 24-hour BP control": the 24-hour BP level, adequate dipping of nocturnal BP (dipper type), and adequate BP variability such as the morning BP surge. The morning BP-guided approach using home BP monitoring (HBPM) is the first step toward perfect 24-hour BP control. After controlling morning HTN, nocturnal HTN is the second target. We have been developing HBPM that can measure nocturnal BP. First, we developed a semiautomatic HBPM device with the function of automatic fixed-interval BP measurement during sleep. In the J-HOP (Japan Morning Surge Home Blood Pressure) study, the largest nationwide home BP cohort, we successfully measured nocturnal home BP using this device with data memory, 3 times during sleep (2, 3, and 4 am), and found that nocturnal home BP is significantly correlated with organ damage independently of office and morning BP values. The second advance was the development of trigger nocturnal BP (TNP) monitoring with an added trigger function that initiates BP measurements when oxygen desaturation falls below a variable threshold continuously monitored by pulse oximetry. TNP can detect the specific nocturnal BP surges triggered by hypoxic episodes in patients with sleep apnea syndrome. We also added the lowest heart rate-trigger function to TNP to detect the "basal nocturnal BP," which is determined by the circulating volume and structural cardiovascular system without any increase in sympathetic tonus. This double TNP is a novel concept for evaluating the pathogenic pressor mechanism of nocturnal BP

  2. Evaluation Study of the Monitoring Result for River Water Environment Component Around U Mining Research Area at, Kalan West Kalimantan from 1997/1998 up to 2002

    The Uranium research which have been carrying out since 1980/1981 up to now and uranium processing activities which was carried out since 1981/1982 to 1996/1997 have probably decreased environment quality. Therefore the environment component would be monitored through Kalan river water every year. From 1997/1998 up to 2002 the environment quality decreased. So, the environment quality is necessarily to be evaluated doing those period. Aim of study is to recover development information of environmental quality at river water component up to 5 years. Evaluation has been done by comparing research the yearly data obtained and construct the correlation with U mining and processing activities on that year. BOD, COD, As, Ca, Mg, Fe, Ni, Zn, Cu, Pb, Mn, Mo and radioactivity of U, Th and Ra content with in Kalan water river tends to become lower in accordance with the decreasing of U mining and processing research activities.

  4. Intercomparison for individual monitoring of external exposure from photon radiation. Results of a co-ordinated research project 1996-1998

    This TECDOC presents the results of a Co-ordinated Research Project on Intercomparison for Individual Monitoring of External Exposure from photon radiation. The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS) have endorsed the use of the operational quantities for monitoring purposes. Specifically, personal dose equivalent, Hp(d), is to be used for individual dosimetry to demonstrate compliance with the exposure limit recommendations, while for workplace area monitoring the ambient dose equivalent and the directional dose equivalent are recommended. In view of the technical difficulties associated with the introduction of these operational quantities the IAEA decided to assist Member States in their provision of appropriate dosimetry for occupational protection. In this respect, intercomparisons have proven to be a cost effective method of providing such support. A Co-ordinated Research Project (CRP) was started in 1997 on Intercomparison for Individual Monitoring of External Exposure from photon radiation, involving more than twenty laboratories from eastern Europe and the countries of the former Soviet Union, and focusing on personnel dosimetry services for nuclear power plants. This CRP was part of the activities of the IAEA Occupational Protection Programme, the objective4s of which are to promote and internationally harmonized approach for optimizing occupational radiation protection through: the development of guides, within the IAEA activities for establishing standards for radiation protection, for restricting radiation exposures in the workplace and for applying current occupational radiation protection techniques, and the promotion of the application of these guidelines. The preparatory phase included, in May 1997, a workshop aimed at familiarizing the participants with the new operational quantities

Results of this literature review and details of the test ing recommendations are presented in this report . FOREWORD To ensure the safe, re liable, and cost - effective long - term operation of nuclear power plants, many systems, structures, and components must be continuously evaluated. The Nuclear Regulatory Commission (NRC) has identified that cables in submerged environments are of concern, particularly as plants are seeking license renewal. To date, there is a lack of consensus on aging and degradation mechanisms even though the area of submerged cables has been extensively studied. Consequently, the ability to make lifetime predictions for submerged cable does not yet exist. The NRC has engaged Sandia National Laboratories (SNL) to lead a coordinated effort to help elucidate the aging and degradation of cables in submerged environments by collaborating with cable manufacturers, utilities, universities, and other government agencies. A team of SNL experts was assembled from the laboratories including electrical condition monitoring, mat erial science, polymer degradation, plasma physics

  7. Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods. Stage 11 and 12. Final report

    This report describes the results obtained during Stage 11 and 12 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. The long-term goals are elaborated in more detail in e.g. the Final Reports of stage 1 and 2 (SKI Report 95:14 and 96:50). Higher order eigenfunctions and eigenvalues of the diffusion equation, describing a static core, have lost their significance when doing calculations in realistic systems, since there are usually made by nodal methods or other direct numerical techniques. However, there are situations when knowledge of the higher order modes is still useful. Such case is the separation of the global and regional flux oscillations in the case of BWR instability. Another case is the investigation of the stability properties of large inhomogeneous cores, which is usually quantified with the so-called eigenvalue separation, ES=1/k1 - 1/k0 where k0 and k1, are the fundamental and first higher order eigenvalues, respectively. Numerical codes used for ICMF calculations usually do not have the option of calculating the higher order eigenvalues and eigenfunctions. In idealised systems, these can be calculated with semi-analytical methods. In order to get insight into the characteristics of the higher order eigenmodes of the neutron flux and the adjoint, these were calculated in a reflected homogeneous system with two-group theory. The adjoint eigenmodes are necessary if an orthogonality property needs to be used, such as the separation of the modes from a flux shape which is a sum of several eigenmodes. At the same time, the so-called numerical noise simulator, developed at the Dept., was extended such that it became suitable for the calculation of the higher order eigenmodes, both direct and adjoint ones. This simulator can treat real inhomogeneous cores, with an input deck compatible with that of SIMULATE. The simulator was used to calculate the eigenfunctions and

    This report describes the results obtained during Stage 11 and 12 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. The long-term goals are elaborated in more detail in e.g. the Final Reports of stage 1 and 2 (SKI Report 95:14 and 96:50). Higher order eigenfunctions and eigenvalues of the diffusion equation, describing a static core, have lost their significance when doing calculations in realistic systems, since there are usually made by nodal methods or other direct numerical techniques. However, there are situations when knowledge of the higher order modes is still useful. Such case is the separation of the global and regional flux oscillations in the case of BWR instability. Another case is the investigation of the stability properties of large inhomogeneous cores, which is usually quantified with the so-called eigenvalue separation, ES=1/k{sub 1} - 1/k{sub 0} where k{sub 0} and k{sub 1}, are the fundamental and first higher order eigenvalues, respectively. Numerical codes used for ICMF calculations usually do not have the option of calculating the higher order eigenvalues and eigenfunctions. In idealised systems, these can be calculated with semi-analytical methods. In order to get insight into the characteristics of the higher order eigenmodes of the neutron flux and the adjoint, these were calculated in a reflected homogeneous system with two-group theory. The adjoint eigenmodes are necessary if an orthogonality property needs to be used, such as the separation of the modes from a flux shape which is a sum of several eigenmodes.

  9. Monitoring of damage on water–cooled cables installed in the Large Hadron Collider (CERN) and research on possible alternatives.

    Wollmann, Alexander; Guillaume, J C; Ricci, D

    To supply the superconducting magnets in the Large Hadron Collider at CERN, several thousand metres of water–cooled cables were installed. These cables consist of a flexible copper core surrounded by a reinforced rubber hose. Although the hose material has been selected carefully, on many cables the rubber hose has suffered from damage. After giving a general overview on common rubber materials and known reasons for their ageing, the technology of water–cooled cables and their special requirements will be introduced. Then, the aim of this thesis is to present the monitoring of the damage on the rubber hoses. This includes an introduction to the monitoring technique used, followed by an analysis and discussion of the results obtained. As a different way of investigating the damage, a pressure test for the rubber hose will be proposed and specified; and the possibility of using alternative conductors for the current supply of the LHC main magnets will be examined. Finally, a series of radiation tests on pot...

  10. MANAGEMENT BOARD MEETING OF 30TH OCTOBER 2003

    2003-01-01

    Status Report on Earned Value Management (EVM) J. Ferguson, the EVM Project Leader, stated that EVM reporting was in a steady phase of operation. Some 1860 work units were currently active, and over 3000 of a total of 10,500 had already been completed. Issues relating to the increasing schedule variance, which was thought to be largely attributable to a sub-optimal definition of the planned value model rather than to delays in activities, were currently under discussion with the LHC Project Leader. Work on the contract alignment tool was nearing completion, with particular attention being paid to improving integration between EVM, the CFU (Contract Follow-Up) tool and the accounting system. Discussions with AB Division had resulted in the launching of a pilot project aimed at establishing a consolidated staff plan by tracking all the Division's activities within the PPT application. An EVM report had been presented to the LHC Cost and Schedule Review Committee at its meeting earlier that week and had been ver...

    Rigby, J.; Locke, M. A.

    2014-12-01

    The Lower Mississippi River Basin (LMRB) is one of the most productive agricultural regions in the United States and has recently become a member of the USDA-ARS Long-term Agricultural Research (LTAR) Network. As the hydrologic gateway to the Gulf of Mexico, the LMRB links agricultural practices and associated runoff and nutrient loads from the Upper Mississippi, Missouri, and Ohio basins with the ecology of the Gulf of Mexico. We review the major challenges for agricultural sustainability in the region and outline a long-term research program within the LTAR Network to address these challenges. Despite the humid climate of the region, water quantity and quality issues are integral to the sustainability of the region. The geography of water-use in the region, current research at plot- to watershed-scales, and knowledge gaps that must be addressed to meet growing production demand will be displayed.

  20. Summary Report of the First Research Coordination Meeting on Nuclear Data for Charged-Particle Monitor Reactions and Medical Isotope Production

    A summary is given of the first IAEA research coordination meeting on ''Nuclear Data for Charged-particle Monitor Reactions and Medical Isotope Production'. Participants reassessed and reviewed the requirements for both cross-section and decay data, based on the earlier findings of three IAEA consultants' meetings (High-precision beta-intensity measurements and evaluations for specific PET radioisotopes, INDC(NDS)-0535, December 2008; Improvements in charged-particle monitor reactions and nuclear data for medical isotope production, INDC(NDS)-0591, September 2011; Intermediate-term nuclear data needs for medical applications: cross sections and decay data, INDC(NDS)-0596, September 2011). While significant emphasis was placed on the needs defined in IAEA report INDC(NDS)-0591, a limited number of relevant items and issues were also considered from the other two technical meetings. Recommendations focused on cross-section studies for a reasonably wide range of targets and projectiles, along with decay data measurements and evaluations for specific radionuclides. Individual presentations and discussions are described in this report, along with listings of the agreed work packages to be undertaken by the participants of the coordinated research project.

    Kitazato, Hiroshi; Kijima, Akihiro; Kogure, Kazuhiro; Hara, Motoyuki; Nagata, Toshi; Fujikura, Kasunori; Sonoda, Akira

    2016-04-01

    On March 11, 2011, huge earthquake with M9.0 took place at Japan Trench area off Northeast Japan. Vigorous disturbances of marine environments and ecosystems have taken place at coastal areas where huge tsunamis swept sediments and organisms away from the coastal areas to deeper oceans. Distributional pattern of sediments and organisms in coves and bays have strongly changed after tsunamis. Marine ecosystems at Northeast Japan have totally disturbed and damaged. Scientists from Tohoku University, the University of Tokyo and JAMSTEC have started to monitor how much marine ecosystem disturbed and how it may recover. A research team, named Tohoku Ecosystem-Associated Marine Sciences, continually makes research on marine ecosystems as ten years monitoring project funded by MEXT, Japan since 2011. On 2016, it takes five years from the Earthquake and Tsunami occurred. What happens marine ecosystems at Tohoku area during these years. Water column ecosystems are rather easy to recover from disturbances. Seaweed communities have strongly damaged, but, they gradually recover. Sediment communities have not recovered yet as sediment distribution is different from before earthquake and tsunamis. Most difficulties are scars in human minds. We, scientists, try to share scientific activities and results with local peoples including fishermen and local governments for better understanding of both oceanic conditions and fishery resources. Disaster risk reduction should accelerate with resilience of community structure. But, mental resilience is the most effective way to recover human activities at the damaged areas.

  2. The data of the long term hydro-pressure monitoring on Mizunami Underground Research Laboratory project from fiscal year 2005 to fiscal year 2008

    Tono Geoscience Center (TGC), Japan Atomic Energy Agency (JAEA) is being performed Mizunami Underground Research Laboratory (MIU) Project, which is a broad scientific study of the deep geological environment as a basis of research and development for geological disposal of nuclear wastes, in order to establish comprehensive techniques for the investigation, analysis and assessment of the deep geological environment in fractured crystalline rock. The MIU Project has three overlapping phases: Surface-based Investigation phase (Phase I), Construction phase (Phase II), and Operation phase (Phase III), with a total duration of 20 years. The main goals of the MIU Project from Phase I through to Phase III are: to establish techniques for investigation, analysis and assessment of the deep geological environment, and to develop a range of engineering for deep underground application. Currently, the project is being carried out under the Phase II. One of the Phase II goals is set to develop and revise models of the geological environment using the investigation results obtained during excavation, and determine and assess the changes in the geological environment in response to excavation. The long term hydro-pressure monitoring has been continued to achieve the Phase II goals. This paper describes the results of the long term hydro-pressure monitoring from April, 2005 to March, 2008. And the data is attached on DVD-ROM. A DVD-ROM is attached as an appendix. (J.P.N.)

  4. Monitoring the Migrations of Wild Snake River Spring/Summer Chinook Salmon Juveniles, 2007-2008 Report of Research.

    Achord, Stephen; Sandford, Benjamin P.; Hockersmith, Eric E. [Northwest Fisheries Science Center

    2009-05-26

    This report provides results from an ongoing project to monitor the migration behavior and survival of wild juvenile spring/summer Chinook salmon in the Snake River Basin. Data reported is from detections of PIT tagged fish during late summer 2007 through mid-2008. Fish were tagged in summer 2007 by the National Marine Fisheries Service (NMFS) in Idaho and by the Oregon Department of Fish and Wildlife (ODFW) in Oregon. Our analyses include migration behavior and estimated survival of fish at instream PIT-tag monitors and arrival timing and estimated survival to Lower Granite Dam. Principal results from tagging and interrogation during 2007-2008 are listed below: (1) In July and August 2007, we PIT tagged and released 7,390 wild Chinook salmon parr in 12 Idaho streams or sample areas. (2) Overall observed mortality from collection, handling, tagging, and after a 24-hour holding period was 1.4%. (3) Of the 2,524 Chinook salmon parr PIT tagged and released in Valley Creek in summer 2007, 218 (8.6%) were detected at two instream PIT-tag monitoring systems in lower Valley Creek from late summer 2007 to the following spring 2008. Of these, 71.6% were detected in late summer/fall, 11.9% in winter, and 16.5% in spring. Estimated parr-to-smolt survival to Lower Granite Dam was 15.5% for the late summer/fall group, 48.0% for the winter group, and 58.5% for the spring group. Based on detections at downstream dams, the overall efficiency of VC1 (upper) or VC2 (lower) Valley Creek monitors for detecting these fish was 21.1%. Using this VC1 or VC2 efficiency, an estimated 40.8% of all summer-tagged parr survived to move out of Valley Creek, and their estimated survival from that point to Lower Granite Dam was 26.5%. Overall estimated parr-to-smolt survival for all summer-tagged parr from this stream at the dam was 12.1%. Development and improvement of instream PIT-tag monitoring systems continued throughout 2007 and 2008. (4) Testing of PIT-tag antennas in lower Big Creek during

    Full Text Available Wild rats, Rattus spp, have adapted so well to urbanization that humans may be obligatory to their survival. Consequently, rats foul human food sources, predate threatened fauna and serve as reservoirs for disease, costing the US economy $19 billion in losses year -1. Urban rat ecology however, remains vastly unexplored because these animals are cryptic, crepuscular, difficult to identify, and hazardous to handle. Additionally, the high-rise buildings that block satellite link-ups, underground sewers and subway tunnels, and rebar enforced concrete covered landscape make it difficult—if not impossible— to track urban animals using traditional radio telemetry. Consequently, there are few ecological studies with free-ranging urban rats. Therefore, we set out to monitor the behaviors and health of free-ranging rats in metropolitan New York. Recognizing that wild rats are attracted to live laboratory-reared conspecifics and that they are sensitive to pheromones, we used soiled rat bedding to repeatedly attract animals to a Remote Frequency Identification (RFID- based antenna with camera-trap and load cell (scale for collecting weights. We captured and micro-chipped 13 rats within 50, 30 and 10 m from our antenna and followed their movements. Seven of the 8 animals released within 10 m of the antenna, visited the RFID antenna lure 398 times over 41 standardized days. Males (2.7 visits day-1 visited the antenna at the same frequency as females (2.7 visits day-1; P>0.5, and both sexes spent similar time dwelling at the pheromones (M, 2.9±0.9 sec; F, 2.4.±0.4 sec; P>0.05. The passive integrated transponder (PIT-tag worked free on the lone individual that did not participate. Within our population, female activity peaked between 6am and 7pm, while males visited throughout the day. Our results demonstrate the potential to safely overcome the primary barriers that have impeded urban rat ecological studies. We used pheromone-based lures to attract

  8. The Use of a New Passive Sampler for Ozone and Nitrogen Oxides Monitoring in Ecological Effects Research

    Franco De Santis

    2001-01-01

    Full Text Available A simple, cost-effective diffusive sampler is described that is suitable for measuring parts per billion (ppb levels of ozone and nitrogen oxides. The diffusive sampler makes use of nitrite for ozone determination whereas for nitrogen oxides and nitrogen dioxide an active carbon tissue impregnated with sodium carbonate is used. Nitrate and nitrite, the formation of which is proportional to the pollutant concentration and sampling duration, are the two species analysed, respectively. Diffusion tubes have the advantage of being a low- cost, convenient way of mapping spatial distributions and investigating long-term trends of ozone and nitrogen oxides. The method is extremely useful for assessing long-term concentrations such as the annual mean for nitrogen oxides, as required by the Daughter Directive 1999/30/EC. Field tests to validate the method have been carried out at an urban background location with co-located passive samplers and continuous measurements of O3 and NOx . An application in ecological effects monitoring for ozone is also presented.

    2012-01-01

    元记忆监测在记忆活动中发挥重要作用。元记忆自FOK研究开始,到理论框架的提出,各种理论逐渐发展成熟。文章从元记忆监测总过程的视角对近年来EOL、FOK、JOL、JOC等元记忆监测成分的研究范式、认知机制及神经机制进行了横向比较,概述了元记忆监测研究的进展及动态。%The metamemory monitoring plays a critical role in the memory activity, enabling the learners to study efficiently. It contains ease of learning (EOL), feeling of knowing (FOK), judge of learning (JOL), and judge of confidence (JOC), which become a con- tinuous process. This paper views the metamemory monitoring as a unitary process and makes a crosswise comparison with the research model, cognitive mechanisms and neural mechanisms of its ingredients, including EOL, FOK, JOL, and JOC. The current major research paradigms were systematically listed. Besides the traditional research model for each one, pre-judgment recall and monitoring (PRAM) and second-order judgment were reviewed for JOL, and game-show was reviewed for FOK. Several major cognitive theory hypotheses were tested. Trace access mechanism for FOK and direct access hypothesis for J0L were based on the strength of the target information. Inferential mechanism for FOK and cue-familiarity hypothesis for JOL and FOK were based on the strength of related information of the target. Accessibility model and competition hypothesis for JOL and FOK were based on the total a- mount of information extracted ; dual-process hypothesis for FOK was based on the separation of FOK and FOnK, and the types of clues perceived. Compared with the neural activations in FOK, JOL, and JOC, activations in ventral medial prefrontal cortex were associated with current FOK and JOL, while activations in medial and lateral parietal regions were associated with JOC. However, compared with recognition tasks, the neural activity related to metamemory was characterized by a shift

    2012-10-01

    High temperature pressure pipes were widely used in the chemical, oil companies and power plants, but the pipe burst incidents occurred from time to time, which had caused some damages on people's lives and property. Thus, in this paper, with the aim to solve this problem, a FBG (FBG: Fiber Bragg Grating) strain gauge structure which consists of three FBGs is designed and fabricated based on the theoretical strain and stress analysis. The strain gauge can be used for the real-time surface strain monitoring of high temperature pressure pipes. In the strain gauge, the elastic hightemperature alloy(10MoWVNb) is chosen as the substrate. The three FBGs with a similar performance are fabricated on the substrate with the high-temperature glue. Among the three FBGs, FBG1 is used for the horizontal strain sensing of high temperature pressure pipes., FBG2 is used for the longitudinal strain of high temperature pressure pipes, and FGB3 is used for temperature compensation. The strain gauge has a feature of high temperature resistance, temperature compensation and two-dimensional strain measurement. The experiment result shows that : the sensing ranges of temperature is 0~300°C, the transverse strain sensitivity is 1.110nm/μɛ, the temperature sensitivity is 0.0213nm/°C; The longitudinal strain sensitivity is 1.104nm/μɛ, the temperature sensitivity is 0.0212nm/°C; the temperature sensitivity is 0.0103nm/°C. Therefore, the strain gauge can meet the needs of the high temperature and pressure pipes.

    Within the research project on the monitoring of foods involving 11 Laender of the Federal Republic of Germany (German Food Contamination Monitoring Programme), selected food items were examined for a number of residues and contaminants by the laboratories of official food control in collaboration with the Centre for Surveillance and Health Evaluation of Environmental Chemicals of the Federal Health Office (ZEBS). In order to guarantee the comparability of analytical results among the 17 laboratories which have participated in the project until March 1990, particular efforts were taken to ensure the quality of analytical data and to harmonize the steps of sampling, sample preparation and recording of data. Samples of beef and pork including several organs, milk, potatoes, lettuce, white cabbage, strawberries and apples were taken according to strictly statistical aspects. Particular attention was paid to the possible seasonal influence on the contamination levels of the products. In the present report, an overview is given of the results obtained up to now for nitrate in foods of vegetal origin and for polychlorinated biphenyls in all food items included in the initial phase of the study.

  15. Co-ordinated research project on isotopic evaluations in infant growth monitoring - a collaboration with WHO (partly RCA). Report on the first research co-ordination meeting

    This Coordinated Research Project (CRP) came about as an initiative to collaborate with the WHO Multicenter Growth Reference Study (MGRS) to generate new growth reference data for breastfed babies using stable isotopes. The WHO MRGS measures growth using anthropometric measurements (e.g. height and weight) in healthy infants and young children in different countries and continents. All participants are fed according to strict criteria regarding duration and frequency of breast-feeding. The MGRS' main goal is to develop a truly international growth standard to look at growth pattern of healthy breast-fed babies. Nevertheless, the composition of the growth (fat/lean tissue) and the nutrient intake that produced the standard growth were not originally included in the study. In order to address these and other important issues related to the baby's body composition and growth, a fruitful collaboration between the WHO and the IAEA has been established. The Agency technical experts and consultants will assist developing countries to carry out isotopic work to measure infant's growth using the in vivo kinetics technique. The objective of this CRP is to measure breast milk intake, using stable isotopes in a subgroup of breast-fed infants growing normally, and to assess their nutrient intakes. Furthermore, the results from the participating projects will provide new and valuable information on the nutrient requirement of healthy breast-fed babies, who were fed according to the WHO standard protocols

    Dasa (Daimler-Benz Aerospace) currently is in charge of an ESA contract for the PRISM feasibility study, including MATRA MS/France and SIRA/UK. The main PRISM mission objectives are to monitor selected target areas with emphasis on bio-chemical stress analyses which are the subject of changes such as vegetation, in particular deforestation; further areas include glaciers, land/water boundaries, and similar features. The Dasa study team makes use of a similar ESA instrument currently the subject of dedicated subunits technology developments, the HRIS (high resolution imaging spectrometer), also lead by Dasa. Its main features and technology developments are covered in a survey. PRISM is covering most of the HRIS features, i.e., it will have an imaging spectrometer segment for the visible/NIR and the SWIR spectrum (450-2350 nm) as HRIS, but implements four MIR and TIR channels to provide surface temperature data, represented by linear detector arrays (essentially the features of another currently pursued ESA development program designated HRTIR). In a first study phase it also included a novel feature, a wide-angle two-axis pointing system for along- and across-track pointing in order to yield multi-directional reflectance data of dedicated targets, which turned out to be the greatest design driver in the instrument, it was omitted in the later phases. The geometric sampling interval is defined to 50 m (design goal) at 50 km swath. PRISM is currently studied in a feasibility study in a competitive way by two teams, one being lead by Dasa. At the time of the Symposium both studies are completed. The results of the Dasa team are presented. Since PRISM covers most of the HRIS mission it is rather likely that in the case of a successful concept feasibility proof (performance and technology wise), it may later replace the HRIS instrument. It is anticipated that a major part of the technology developments currently performed for HRIS will be utilized -- with some

    Multivariate statistics comprise a set of statistical methods used in situations where many variables are database space subsets. Initially applied to human, social and biological sciences, these methods are being applied to many other areas such as education, geology, chemistry, physics, engineering, and many others. This spectra expansion was possible due to recent technological development of computation hardware and software that allows high and complex databases to be treated iteratively enabling further analysis. Following this trend, the neural networks called Self-Organizing Maps are turning into a powerful tool on visualization of implicit and unknown correlations in big sized database sets. Originally created by Kohonen in 1981, it was applied to speech recognition tasks. The SOM is being used as a comparative parameter to evaluate the performance of new multidimensional analysis methodologies. Most of methods require good variable input selection criteria and SOM has contributed to clustering, classification and prediction of multidimensional engineering process variables. This work proposes a method of applying SOM to a set of 58 IEA-R1 operational variables at IPEN research reactor which are monitored by a Data Acquisition System (DAS). This data set includes variables as temperature, flow mass rate, coolant level, nuclear radiation, nuclear power and control bars position. DAS enables the creation and storage of historical data which are used to contribute to Failure Detection and Monitoring System development. Results show good agreement with previous studies using other methods as GMDH and other predictive methods. (author)

The research pro-vided basic guiding and practical experiences for the underground microseismic monitoring and disaster prevention in side slopes or tunnels engineering.

  19. Contamination monitoring of Na 131 I levels in therapy unit of Research Institute for Nuclear Medicine, Tehran University of Medical Sciences by indirect method (Wipe test)

    Contamination with radiopharmaceuticals in nuclear medicine centres in addition to being a health concern requires time consuming decontamination efforts. According to Nuclear Regulatory Commission Contamination should be monitored in nuclear medicine centers where radiopharmaceuticals are prepared and administrated at the end of each working session; otherwise, contamination spread to other areas not only equipment but also personnel and other people will be expected. The wipe test for the presence of radioactivity is accomplished by wiping the surface over an area approximately 100 cm2 with an absorbent paper, then counting it in an appropriate radiation detector. In this study, contamination monitoring of patient's rooms (4 rooms), entrance corridor, patient's corridor, waiting room, control room (nursing station), radiopharmaceutical storage room in therapy unit of Research Institute for Nuclear Medicine, Shariati hospital was performed by indirect method. Based on the results, some areas including storage room were contaminated. There was also a direct relationship between dose administrated and levels of contamination in patient's rooms. Regarding high uptake of iodine by thyroid gland and damaging effects of Na131 I, weekly wipe tests are required to determine the level of contamination. Patient's rooms after discharging the patients and before re hospitalization specially should be checked. If these tests reveal contamination over standard levels, appropriate decontamination procedures should be carried out immediately

  20. Decommissioning of TRIGA-reactors and other nuclear research facilities. Aims of the German working group for incorporation monitoring

    In 2001 the working group decommissioning was founded in the department incorporation of the German/Switzerland association for radiation protection. Members of the group are representatives of dismantling projects, dismantling companies, organizations of experts, authorities, institutions of measuring incorporations, research facilities and universities. Aims of the group are to guarantee a continuous information and experience exchange between the different decommissioning projects, to establish criteria for facility specific advanced training and further education, to propose requirements for in-vitro incorporation measuring facilities and to draw up a recommendation for incorporation protection of decommissioning projects. It is tried to harmonize the procedure in principle regarding the specific conditions of the different nuclear facilities. The bases for the recommendation are formed by the experiences of the previous dismantling projects in Germany. As an example in this contribution the procedure at the TRIGA reactor of MHH is presented and compared to a facility with alpha-emitters. (author)

    Four non-vitamin K antagonist oral anticoagulants (dabigatran, rivaroxaban, apixaban, and edoxaban) have been approved in the United States for treatment of atrial fibrillation (AF) and venous thromboembolic disease. They have been as or more effective than the prior standards of care, with less fatal or intracranial bleeding, fewer drug and dietary interactions, and greater patient convenience. Nonetheless, the absence of the ability for clinicians to assess compliance or washout with a simple laboratory test (or to adjust dosing with a similar assessment) and the absence of an antidote to rapidly stop major hemorrhage or to enhance safety in the setting of emergent or urgent surgery/procedures have been limitations to greater non-vitamin K antagonist oral anticoagulant usage and better thromboembolic prevention. Accordingly, a Cardiac Research Safety Consortium "think tank" meeting was held in February 2015 to address these concerns. This manuscript reports on the discussions held and the conclusions reached at that meeting. PMID:27297852

  2. Using remotely sensed imagery and GIS to monitor and research salmon spawning: A case study of the Hanford Reach fall chinook (Oncorhynchus Tshawytscha)

    The alteration of ecological systems has greatly reduced salmon populations in the Pacific Northwest. The Hanford Reach of the Columbia River, for example, is a component of the last ecosystem in eastern Washington State that supports a relatively healthy population of fall chinook salmon ([Oncorhynchus tshawytscha], Huntington et al. 1996). This population of fall chinook may function as a metapopulation for the Mid-Columbia region (ISG 1996). Metapopulations can seed or re-colonize unused habitat through the mechanism of straying (spawning in non-natal areas) and may be critical to the salmon recovery process if lost or degraded habitat is restored (i.e., the Snake, Upper Columbia, and Yakima rivers). For these reasons, the Hanford Reach fall chinook salmon population is extremely important for preservation of the species in the Columbia River Basin. Because this population is important to the region, non-intrusive techniques of analysis are essential for researching and monitoring population trends and spawning activities

    The concern about the role of aerosols as to their effect in the Earth-Atmosphere system requires observation at multiple temporal and spatial scales.The Moderate Resolution Imaging Spectroradiameters (MODIS) is the main aerosol optical depth (AOD)monitoring satellite instrument,and its accuracy and uncertainty need to be validated against ground based measurements routinely.The comparison between two ground AOD measurement programs,the United States Department of Agriculture (USDA) Ultraviolet-B Monitoring and Research Program (UVMRP) and the Aerosol Robotic Network (AERONET) program,confirms the consistency between them.The intercomparison between the MODIS AOD,the AERONET AOD,and the UVMRP AOD suggests that the UVMRP AOD measurements are suited to be an alternative ground-based validation source for satellite AOD products.The experiments show that the spatial-temporal dependency between the MODIS AOD and the UVMRP AOD is positive in the sense that the MODIS AOD compare more favorably with the UVMRP AOD as the spatial and temporal intervals are increased.However,the analysis shows that the optimal spatial interval for all time windows is defined by an angular subtense of around 1° to 1.25°,while the optimal time window is around 423 to 483 minutes at most spatial intervals.The spatial-temporal approach around 1.25° & 423 minutes shows better agreement than the prevalent strategy of 0.25° & 60 minutes found in other similar investigations.Research Program (UVMRP),Aerosol Robotic Network (AERONET),Moderate Resolution Imaging Spectroradiameters (MODIS),validation,spatial-temporal approach

  5. Monitoring Isotopes in Rivers: Creation of the Global Network of Isotopes in Rivers (GNIR). Results of a Coordinated Research Project 2002-2006

    River runoff plays a key role in human development in all societies through the provision of water for agriculture, industry and domestic use. Although the monitoring of water availability and our understanding of the main hydrological processes at the catchment scale are relatively good, many important aspects, especially those related to the interaction of runoff and groundwater, remain poorly understood. Additionally, the impact of human activities - such as the construction of large reservoirs and diversions, and the redirection of rivers to supply drinking water or water for irrigation or hydropower - are highly relevant and, together with the predicted impact of climate change, are likely to heavily impact local water cycles. The effects of such changes include: limited availability of water; changes in flood or drought frequency; changes in water quality, sediment load and groundwater recharge; and biodiversity loss in riparian environments. Additionally, political disputes may result as water resources become affected in terms of availability and/or quality. In most instances, stable isotopes and other water tracers provide a deeper insight into hydrological processes, especially in aspects related to water pathways, interconnections, transport of water and pollutants, and the transit time of water. To explore the contribution of these techniques in more detail, the IAEA has launched a monitoring programme, the Global Network of Isotopes in Rivers (GNIR), aimed at regular analysis of the isotope composition of runoff in large rivers. This isotope monitoring network complements an earlier precipitation network, the Global Network of Isotopes in Precipitation (GNIP). To prepare for GNIR, the IAEA launched a coordinated research project (CRP) called Design Criteria for a Network to Monitor Isotope Compositions of Runoff in Large Rivers. The main aim of the CRP was to develop a scientific rationale and a protocol for the operation of such a network, as well as

    The Grand Canyon Monitoring and Research Center measures the effects of Glen Canyon Dam operations on the resources along the Colorado River from Glen Canyon Dam to Lake Mead in support of the Grand Canyon Adaptive Management Program. Control points are integral for geo-referencing the myriad of data collected in the Grand Canyon including aerial photography, topographic and bathymetric data used for classification and change-detection analysis of physical, biologic and cultural resources. The survey department has compiled a list of 870 control points installed by various organizations needing to establish a consistent reference for data collected at field sites along the 240 mile stretch of Colorado River in the Grand Canyon. This list is the foundation for the Control Point Database established primarily for researchers, to locate control points and independently geo-reference collected field data. The database has the potential to be a valuable mapping tool for assisting researchers to easily locate a control point and reduce the occurrance of unknowingly installing new control points within close proximity of an existing control point. The database is missing photographs and accurate site description information. Current site descriptions do not accurately define the location of the point but refer to the project that used the point, or some other interesting fact associated with the point. The Grand Canyon Monitoring and Research Center (GCMRC) resolved this problem by turning the data collection effort into an educational exercise for the participants of the Grand Canyon Youth organization. Grand Canyon Youth is a non-profit organization providing experiential education for middle and high school aged youth. GCMRC and the Grand Canyon Youth formed a partnership where GCMRC provided the logistical support, equipment, and training to conduct the field work, and the Grand Canyon Youth provided the time and personnel to complete the field work.

  7. Development and Use of Astronomy-Like Devices for UFO Monitoring: A Research Project for the Study of UFO Physics

    Teodorani, M.

    A research project aimed at studying unidentified atmospheric `nocturnal lights' in world areas of recurrence is presented. In such a context targets are considered and treated on a par with celestial and/or atmospheric objects having no fixed coordinates. Such a project involves the use of a battery of 20 mini-telescopes which can be interchangeable with wide-field lenses. Both types of light collectors, which are intended to work in the near-IR, optical and near-UV ranges, are planned to be connected to detectors for CCD imaging and fast photon-counting photometry, to objective-prisms for low-resolution spectroscopy and to grism-slit spectrographs for high-resolution spectroscopy. The overall measurement instrumental platform is intended to be guided simultaneously by a radar, by an IR alarm sensor and by a laser telemetric device in order to allow physical scientists to search, point and track a given bright flying object which is characterized supposedly by random motions. Finally, physical informations which are expected to come out from data analysis are presented and discussed in detail.

    This article, through literature consultation, video observation, mathematical statistics and comparative analysis, makes a study of the offensive and defensive techniques of the main defenders from Chinese and foreign women’s basketball teams in the 30th Olympic Games in London. Results show that, compared with the powerful teams in the world, the main defenders of the Chinese women’s basketball team need to improve their techniques of shooting, rebounds, stealing the ball, block shots and organization. And when facing the opponents’ oppressive defense, the Chinese basketball players have poor shooting and can not give full play to the peripheral offensive advantage.%  运用文献资料法、录像观察法、数理统计法、对比分析法,对第30届奥运会中外女子篮球主力后卫攻防技术指标进行研究分析。结果表明:与世界强队相比,中国女篮的主力后卫队员在投篮技术运用、篮板球、抢断球、盖帽与组织技术等方面有待提高。而且当面对对手压迫性防守时,进攻投篮命中率较差,并没有充分发挥外围的进攻优势。

    Valuable achievements on differential optical absorption spectroscopy (DOAS) for monitoring atmospheric pollutants gas have been made in the past decades. Based on the idea of setting the threshold according to the maximum value, symbolized as OD'm, of differential optical density, the algorithm of traditional DOAS was combined with the DOAS algorithm based on the kalman filtering to improve the detection limit without losing measurement accuracy in the present article. Two algorithms have different inversion accuracy at the same ratio of signal to noise and the problem of inversion accuracy was well resolved by combining two algorithms at short light path length. Theoretical and experimental research on the concentration measurement of SO2 in the flue gases was carried out at the normal temperature and atmospheric pressure. The research results show that with the OD'm less than 0.0481, the measurement precision is very high for SO2 with the improved DOAS algorithm. The measurement lower limit of SO2 is less than 28.6 mg x m(-3) and the zero drift of the system is less than 2.9 mg x m(-3). If the OD'm is between 0.0481 and 0.9272, the measurement precision is high with the traditional DOAS algorithm. However, if the OD'm is more than 0.922, the errors of measurement results for both two DOAS algorithms are very large and the linearity correction must be performed. PMID:19626898

  11. Rapid instrumental and separation methods for monitoring radionuclides in food and environmental samples. Final report on an IAEA co-ordinated research programme

    The Co-ordinated Research Programme (CRP) on Rapid Instrumental and Separation Methods for Monitoring Radionuclides in Food and Environmental Samples was established by the Agency following a Consultants' Meeting on the same topic, which was held 5-9 September 1988 in Vienna. It was completed in 1992. At various times during its course it encompassed 15 participants from 14 countries. The scope of work and objectives of the CRP were established at the Consultants' Meeting. It was agreed that the CRP should focus on the development of rapid methods for the determination of radionuclides in food and environmental samples during the intermediate and late post-accident phases. The rapid methods developed during the course of the CRP were intended to permit a timely and accurate determination of radionuclides at concentrations at least one order of magnitude below those specified for Derived Intervention Levels (DILs) for food by the WHO/FAO and the IAEA. Research Co-ordination meetings were held in Warsaw, Poland in September 1989 and in Vienna, Austria in 1991. Reports of the meetings are available from the Agency on Request. This document comprises copies of final reports from the participants and selected contributions presented by the participants at the meetings. The contributions were selected on the basis of being able to stand alone, without further explanation. Where there was an overlap in the information presented by a participant at both meetings, the most complete contribution was selected

    -salinerrock multiphase system. The accurate simulation results can provide a theoretical basis for important practical problems such as the choice of sequestration scheme, monitoring methods and the choice of sequestration location. Therefore, it is necessary to enhance sequestration-related research of multi-component multi-phase flow transport simulation in porous media and of geochemical reaction simulation. After injection of carbon dioxide into underground reservoirs, long time monitoring is needed to detect the migration of sequestrated carbon dioxide, and to find the leakage and take appropriate response measures. Seismic monitoring method is one of the most important ways among all the monitoring methods, and 4D seismic monitoring has been implemented in several large-scale sequestration projects all over the world and achieved good results. To make seismic monitoring methods more accurate, and to achieve effective or real-time monitoring, it is important to not only develop rock physics theories and methods, but also involve special aspects of carbon sequestration into the rock physics research, that is, changes in rock physical properties caused by carbon dioxide dissolution and chemical reactions. This is a fundamental research and issue of great theoretical and practical significance in the study of the earth environment and global climate change and other major scientific issues.

    The results of 25 years of monitoring and research in the Loch Vale watershed in Rocky Mountain National Park, Colorado documented ecological effects of nitrogen (N) deposition on alpine and subalpine ecosystems, including changes in soils, terrestrial and aquatic vegetation, and surface-water chemistry. The large body of evidence using various approaches to study diverse components of the ecosystem made a compelling case for the need to reduce atmospheric N deposition in the park, which is federally protected from degradation by any form of air pollution. In 2005, state and federal agencies signed a memorandum of understanding agreeing to work together to reverse the trend of increasing N deposition in the park. Critical loads of nitrogen deposition must now be determined that protect all components of the ecosystem, then target loads must be set as a first step toward emissions reductions. Cost-effective implementation of target loads will require advances in scientific understanding of relative contributions from different source categories and source areas of N emissions. Currently, atmospheric deposition is 4-6 kg N/ha, with just under half in the form of ammonium. Sources include power production, industry, and the transportation sector as well as agricultural emissions from crop and livestock production. Ongoing studies are incorporating atmospheric modeling and natural tracers such as stable isotopes to better define source attribution and spatial distribution of N deposition.

    In terms of algorithmic problem of criterion limit of monitoring point under the effect of multi-electromagnetic radiation pollution sources in the spatial field, we put up a formula of criterion limit of monitoring point based on distance factor algorithm. The algorithm not only can solve the computations of criterion limits of monitoring point at certain time under the effect of multi-electromagnetic radiation pollution sources, but can compute the criterion limits of all monitoring points at any time,which has important instructions for working out electromagnetic environment criterion.

  5. Report on the third research co-ordination meeting of the coordinated research project: 'The development of strategies for the effective monitoring of veterinary drug residues in livestock and livestock products in developing countries' (D3.20.22)

    The third RCM for the CRP on the development of strategies for the effective monitoring of veterinary drug residues in livestock and livestock products in developing countries was held in Natal, Brazil, from 11-15 April 2005. The meeting was attended by ten Research Contract Holders, a second representative of the research group of the host country, two Research Agreement Holders, two Technical Contract Holders and the Scientific Secretary. The work in the second phase of this CRP has built upon the progress reported from the first phase, resulting in good quality immunoassay reagents, confirmatory methods and a number of validated methods. It is recommended that all contracts (with one exception), including technical contracts, be renewed to facilitate the completion of the work plans agreed at the meeting. A protocol for the validation of immunoassays will be provided by a Research Agreement Holder. The protocol has already been successfully applied for validation of an RIA method in Brazil. It is recommended that this protocol be adopted by all participants in the project to harmonize the validation of immunoassay methods developed. Work on the development of the 125I-radioimmunoassay for chloramphenicol has not been satisfactory. It is recommended that this work is transferred to the research group in Brazil. The meeting agreed that the FAO/IAEA Joint Division's INFOCRIS database and associated e-learning modules are a very useful resource for developing country scientists. It is recommended to proceed with the expansion of the database as planned. In addition, it was suggested that a database and bibliography of original literature on, for example, pharmacokinetic and metabolism studies on veterinary drugs and hormonal growth promoters should be included. Much of this data was published many years ago and is very difficult to access, but is of importance in the design and development of methods. Some of the results generated by CRP participants should be

    2016-05-01

    Study Design Surgeon survey. Objective To analyze multimodal intraoperative monitoring (MIOM) for different combinations of methods based on the collected data and determine the best combination. Methods A questionnaire was sent to 72 training institutions to analyze and compile data about monitoring that had been conducted during the preceding 5 years to obtain data on the following: (1) types of monitoring; (2) names and number of diseases; (3) conditions of anesthesia; (4) condition of stimulation, the monitored muscle and its number; (5) complications; and (6) preoperative and postoperative manual muscle testing, presence of dysesthesia, and the duration of postoperative motor deficit. Sensitivity and specificity, false-positive rates, and false-negative rates were examined for each type of monitoring, along with the relationship between each type of monitoring and the period of postoperative motor deficit. Results Comparison of the various combinations showed transcranial electrical stimulation motor evoked potential (TcMEP) + cord evoked potential after stimulation to the brain (Br-SCEP) combination had the highest sensitivity (90%). The TcMEP + somatosensory evoked potential (SSEP) and TcMEP + spinal cord evoked potential after stimulation to the spinal cord (Sp-SCEP) combinations each had a sensitivity of 80%, exhibiting little difference between their sensitivity and that obtained when TcMEP alone was used. Meanwhile, the sensitivity was as low as 50% with Br-SCEP + Sp-SCEP (i.e., the cases where TcMEP was not included). Conclusions The best multimodality combination for intraoperative spinal cord monitoring is TcMEP + Br-SCEP, which had the highest sensitivity (90%), the lowest false-positive rate (6.1%), and the lowest false-negative rate (0.2%).

  8. Charged particle cross-section database for medical radioisotope production: diagnostic radioisotopes and monitor reactions. Final report of a co-ordinated research project

    Medical applications of nuclear radiation are of considerable interest to the IAEA. Cyclotrons and accelerators, available in recent years in an increasing number of countries, are being used for the production of radioisotopes for both diagnostic and therapeutic purposes. The physical basis of this production is described through interaction of charged particles, such as protons, deuterons and alphas, with matter. These processes have to be well understood in order to produce radioisotopes in an efficient and clean manner. In addition to medical radioisotope production, reactions with low energy charged particles are of primary importance for two major applications. Techniques of ion beam analysis use many specific reactions to identify material properties, and in nuclear astrophysics there is interest in numerous reaction rates to understand nucleosynthesis in the Universe. A large number of medically oriented cyclotrons have been running in North America, western Europe and Japan for more than two decades. In recent years, 30-40 MeV cyclotrons and smaller cyclotrons (Ep < 20 MeV) have been installed in several countries. Although the production methods are well established, there are no evaluated and recommended nuclear data sets available. The need for standardization was thus imminent. This was pointed out at three IAEA meetings. Based on the recommendations made at these meetings, the IAEA decided to undertake and organize the Co-ordinated Research Project (CRP) on Development of Reference Charged Particle Cross-Section Database for Medical Radioisotope Production. The project was initiated in 1995. It focused on radioisotopes for diagnostic purposes and on the related beam monitor reactions in order to meet current needs. It constituted the first major international effort dedicated to standardization of nuclear data for radioisotope production. It covered the following areas: Compilation of data on the most important reactions for monitoring light ion

  9. Lunar Health Monitor (LHM)

    Lisy, Frederick J.

    2015-01-01

    Orbital Research, Inc., has developed a low-profile, wearable sensor suite for monitoring astronaut health in both intravehicular and extravehicular activities. The Lunar Health Monitor measures respiration, body temperature, electrocardiogram (EKG) heart rate, and other cardiac functions. Orbital Research's dry recording electrode is central to the innovation and can be incorporated into garments, eliminating the need for conductive pastes, adhesives, or gels. The patented dry recording electrode has been approved by the U.S. Food and Drug Administration. The LHM is easily worn under flight gear or with civilian clothing, making the system completely versatile for applications where continuous physiological monitoring is needed. During Phase II, Orbital Research developed a second-generation LHM that allows sensor customization for specific monitoring applications and anatomical constraints. Evaluations included graded exercise tests, lunar mission task simulations, functional battery tests, and resting measures. The LHM represents the successful integration of sensors into a wearable platform to capture long-duration and ambulatory physiological markers.

  10. Report of the second research co-ordination meeting on the co-ordinated research programme: rapid instrumental and separation methods for monitoring radionuclides in food and environmental samples

    The purpose of this Second Research Co-ordinated Meeting (12-16 August 1991) on Rapid Instrumental and Separation Methods for Monitoring Radionuclides in Food and Environmental Samples is to discuss the progress of the programmes since the First Research Co-ordination Meeting, discuss how to validate the methodologies developed (e.g. reference samples, intercomparisons), and outline a schedule for CRP completion by the end of 1992. Radioactive contamination of the environment after a nuclear accident, such as had occurred at Chernobyl, is of serious concern to government officials and members of the general public. In 1990/1991 the Agency was asked to organize the International Chernobyl Project to assess the situation in the USSR. A network of laboratories was organized to carry out the environmental assessment needed for this project. The following recommendations are based on the experience gained by many of the laboratories involved in this project. 1. Maintain a network of analytical laboratories with special skills and experience to provide assessments of radionuclide contamination in the environment in case of a radiological emergency. 2. Methodologies for assessment of contamination in the environment should take into consideration potential trajectories, radioecology, and food chain parameters. 3. Focus on areas of representative sample collection, is situ instrumental and chemical analysis, as well as advanced streamlined laboratory analyses which will facilitate the timeline of an assessment. 4. Conduct intercomparison and testing of technologies, employing standard reference materials and procedures, and field measurements at significantly contaminated area. 5. Conduct training of Member State laboratory personnel through fellowships, special courses, and workshops. 5 refs

  11. Improving radiation data quality of USDA UV-B monitoring and research program and evaluating UV decomposition in DayCent and its ecological impacts

    Chen, Maosi

    Solar radiation impacts many aspects of the Earth's atmosphere and biosphere. The total solar radiation impacts the atmospheric temperature profile and the Earth's surface radiative energy budget. The solar visible (VIS) radiation is the energy source of photosynthesis. The solar ultraviolet (UV) radiation impacts plant's physiology, microbial activities, and human and animal health. Recent studies found that solar UV significantly shifts the mass loss and nitrogen patterns of plant litter decomposition in semi-arid and arid ecosystems. The potential mechanisms include the production of labile materials from direct and indirect photolysis of complex organic matters, the facilitation of microbial decomposition with more labile materials, and the UV inhibition of microbes' population. However, the mechanisms behind UV decomposition and its ecological impacts are still uncertain. Accurate and reliable ground solar radiation measurements help us better retrieve the atmosphere composition, validate satellite radiation products, and simulate ecosystem processes. Incorporating the UV decomposition into the DayCent biogeochemical model helps to better understand long-term ecological impacts. Improving the accuracy of UV irradiance data is the goal of the first part of this research and examining the importance of UV radiation in the biogeochemical model DayCent is the goal of the second part of the work. Thus, although the dissertation is separated into two parts, accurate UV irradiance measurement links them in what follows. In part one of this work the accuracy and reliability of the current operational calibration method for the (UV-) Multi-Filter Rotating Shadowband Radiometer (MFRSR), which is used by the U.S. Department of Agriculture UV-B Monitoring and Research Program (UVMRP), is improved. The UVMRP has monitored solar radiation in the 14 narrowband UV and VIS spectral channels at 37 sites across U.S. since 1992. The improvements in the quality of the data result

  12. In-Orbit Monitoring of Space Weather and Its Effects on Commercial- Off-The-Shelf (COTS) Electronics - A Decade of Research Using Micro-Satellites

    Underwood, Craig I.; Sweeting, Martin, , Sir

    2002-01-01

    Over the past 20 years the University of Surrey has gained significant experience in the use of commercial-off-the-shelf (COTS) devices operating in low-Earth orbit through the design, manufacture, launch and operation of more than a dozen "UoSAT" micro-satellites. The deleterious effects of the ionising radiation environment is of particular concern when using COTS technologies in space, and over the last decade, particular emphasis has been given to a programme of monitoring "space weather" in terms of the high energy proton and heavy-ion cosmic-ray environment these spacecraft encounter, and to observing and analysing its effects - particularly with regard to single-event effects - upon the COTS devices on-board. The extended period of research has enabled a wide variety of conditions to be observed ranging across an entire solar cycle. This paper reports on the environment and effects observed, and describes the various methodologies that have been used to minimise the risk associated with the use of COTS devices in space. The practical importance of resilient error-detection and correction coding schemes to protect spacecraft data and control software is shown, as is the need for adequate levels of shielding against total ionising radiation dose. The relative effects of Galactic-Cosmic-Rays (GCRs), Solar Proton Events (SPEs) and trapped proton environments in Low-Earth orbit are discussed, and more recent flight data extends these observations out to very high orbit - approx 60,000 km altitude. As well as gaining practical data on space weather and its effects on advanced electronics, the research has resulted in the design and construction of a series of inexpensive, compact, and low- power particle detectors, which are capable of providing routine environmental "health" warnings for future operational spacecraft. Low cost micro-satellites have proven to be ideal vehicles for quick response and cost effective space technology verification missions, where

    Alekanyan, T. M.; Dorman, L. I.; Yanke, V. G.; Korotkov, V. K.

    1985-01-01

    The latitudinal behavior of intensities and multiplicities was registered by the neutron monitor 2 NM and the lead-free neutron monitor 3 SND (slow-neuron detector) in the equator-Kaliningrad line in the Atlantic Ocean. Coupling coefficients for 3 SND show the sensitivity of this detector to primary particles of cosmic rays of energies on the average lower than for 2 NM. As multiplicities increase, the coupling coefficients shift towards higher energies.

  20. Monitoring and research to describe geomorphic effects of the 2011 controlled flood on the Green River in the Canyon of Lodore, Dinosaur National Monument, Colorado and Utah

    Mueller, Erich R.; Grams, Paul E.; Schmidt, John C.; Hazel, Joseph E., Jr.; Kaplinski, Matt; Alexander, Jason A.; Kohl, Keith

    2014-01-01

    In 2011, a large magnitude flow release from Flaming Gorge Reservoir, Wyoming and Utah, occurred in response to high snowpack in the middle Rocky Mountains. This was the third highest recorded discharge along the Green River downstream of Flaming Gorge Dam, Utah, since its initial closure in November 1962 and motivated a research effort to document effects of these flows on channel morphology and sedimentology at four long-term monitoring sites within the Canyon of Lodore in Dinosaur National Monument, Colorado and Utah. Data collected in September 2011 included raft-based bathymetric surveys, ground-based surveys of banks, channel cross sections and vegetation-plot locations, sand-bar stratigraphy, and painted rock recovery on gravel bars. As part of this surveying effort, Global Navigation Satellite System (GNSS) data were collected at benchmarks on the canyon rim and along the river corridor to establish a high-resolution survey control network. This survey control network allows for the collection of repeatable spatial and elevation data necessary for high accuracy geomorphic change detection. Nearly 10,000 ground survey points and more than 20,000 bathymetric points (at 1-meter resolution) were collected over a 5-day field campaign, allowing for the construction of reach-scale digital elevation models (DEMs). Additionally, we evaluated long-term geomorphic change at these sites using repeat topographic surveys of eight monumented cross sections at each of the four sites. Analysis of DEMs and channel cross sections show a spatially variable pattern of erosion and deposition, both within and between reaches. As much as 5 meters of scour occurred in pools downstream from flow constrictions, especially in channel segments where gravel bars were absent. By contrast, some channel cross sections were stable during the 2011 floods, and have shown almost no change in over a decade of monitoring. Partial mobility of gravel bars occurred, and although in some locations

    We discuss contemporary theories in mathematics education in order to do research on research. Our strategy consists of analysing discursively and ideologically recent key publications addressing the role of theory in mathematics education research. We examine how the field fabricates its object of...... research by deploying Foucault’s notion of bio-politics - mainly to address the object “learning” - and Žižek’s ideology critique - to address the object “mathematics”. These theories, which have already been used in the field to research teaching and learning, have a great potential to contribute to a...... reflexivity of research on its discourses and effects.

    By virture of Republic Act 2067, as amended the Philippine Atomic Energy Commission (PAEC), now renamed Philippine Nuclear Research Institute (PNRI) is the government agency charged with the regulations and control of radioactive materials in the Philippines. The protection against the hazards of non-ionizing radiation is being monitored by the Radiological Health Service (RHS) of the Department of Health pursuant to the provision of Presidental Decree 480. The RHS issues licenses for possession, handling, and use of x-ray machines and equipment, both industrial and medical, and provide radiation protection training to x-ray technologists and technicians. As part of its regulatory function, the PNRI is charged with the responsibility of assuring that the radiation workers and the public are protected from the hazards associated with the possession, handling, production, manufacturing, and the use of radioactive materials and atomic energy facilities in the Philippines. The protection of radiation workers from the hazards of ionizing radiation has always been a primary concern of PNRI and by limiting the exposure of radiation workers, the risk to population is kept to within acceptable level. In this paper, the following items are described: radiation protection program, radiation protection services, radiation control, and problems encountered/recommendation. (G.K.)

    This report covers the first three years of comprehensive monitoring and evaluation of the Umatilla Hatchery. Because the hatchery and the evaluation study and the fish health monitoring investigations are in the early stages of implementation, much of the information contained in this report is preliminary. The majority of the data that is crucial for evaluating the success of the hatchery program, the data on post-release performance and survival, is yet unavailable. In addition, several years of data are necessary to make conclusions about rearing performance at Umatilla Hatchery. The conclusions drawn in this report should be viewed as preliminary and should be used in conjunction with additional information as it becomes available
