    2015-06-15

    The International Electrotechnical Commission (IEC) writes standards that manufacturers of electrical equipment must comply with. Medical electrical equipment, such as medical imaging, radiation therapy, and radiation dosimetry devices, fall under Technical Committee 62. Of particular interest to medical physicists are the standards developed within Subcommittees (SC) 62B, which addresses diagnostic radiological imaging equipment, and 62C, which addresses equipment for radiation therapy, nuclear medicine and dosimetry. For example, a Working Group of SC 62B is responsible for safety and quality assurance standards for CT scanners and a Working Group of SC 62C is responsible for standards that set requirements for dosimetric safety and accuracy of linacs and proton accelerators. IEC standards thus have an impact on every aspect of a medical physicist’s job, including equipment testing, shielding design, room layout, and workflow. Consequently, it is imperative that US medical physicists know about existing standards, as well as have input on those under development or undergoing revision. The structure of the IEC and current standards development work will be described in detail. The presentation will explain how US medical physicists can learn about IEC standards and contribute to their development. Learning Objectives: Learn about the structure of the IEC and the influence that IEC standards have on the design of equipment for radiology and radiation therapy. Learn about the mechanisms by which the US participates in the development and revision of standards. Understand the specific requirements of several standards having direct relevance to diagnostic and radiation therapy physicists.

    Of over 4700 nuclear and radiation protection standards, laws, regulations, recommendations, etc., which have been issued by 52 countries and several governmental international organizations such as IAEA, or non-government organizations such as ICRP, ICRU, ISO and IEC, more than 90% are national, and more than half of those of a non-regulatory nature. Both number and importance of international standards are, however, increasing. The two most important non-governmental international standards organizations are the International Organization for Standardization (ISO), which founded a Technical Committee (TC) 85 'Nuclear Energy' with several Sub-Committees in 1957, and the closely associated International Electrotechnical Commission (IEC) with its TC 45 'Nuclear Instrumentation' formed in 1960. There are over 20 member countries actively participating in the work in each of them, with additional observer countries and liaison to the relevant other international organizations. A brief review is given on some of the experience which has been gained by ISO/TC 85 and IEC/TC 45, and its work program and accomplishments, considering in particular recent developments. It covers nuclear safety and instrumentation, radiation protection, and the nuclear fuel cycle, as well as interface issues including definitions and terminology, interaction of the activities with the work of other national and international bodies, etc. Some problem areas are also briefly discussed.

    Ramos, V.; Ringwood, John V.

    2016-01-01

    Highlights: • The utility of the International Electrotechnical Commission standards for tidal stream resource assessment were analysed. • The Orkney Region (N Scotland) was used as a case study. • A sensitivity analysis in terms of accuracy vs computational times was carried out for different mesh resolutions. • Modelling the operation of a tidal energy converter becomes essential for an appropriate estimation of the tidal resource. • Practical recommendations are proposed for future editions of the technical standard. - Abstract: Over the next decades, tidal stream energy aims to become a fully commercially viable energy source. For this purpose, complete knowledge regarding tidal stream resource assessment is essential. In this context, the International Electrotechnical Commission has developed a technical standard for the assessment of the tidal stream resource, “IEC 62600-201 TS: Marine energy - Wave, tidal and other water current converters - Part 201: Tidal energy resource assessment and characterisation”, offering a vast set of recommendations in the fields of data collection, numerical modelling, data analysis and reporting of the results with the purpose of standardising tidal stream resource characterisation. The standard divides resource assessments into two different classes: feasibility and layout design. The model setup procedure (mesh resolution, boundary conditions) and the computational effort required vary significantly from one class to another. For these reasons, the objective of the present work is to explore the proposed standard using the Orkney Region (N Scotland) as a case study. Overall, it was found that the standard works well, offering a detailed characterisation of the tidal resource; however, in order to improve its manageability, some aspects related to the grid resolution requirements and the approach to model a tidal energy converter could be revisited for future editions.

    The development of MS ISO 9001 and MS ISO/ IEC 17025 in Malaysian Nuclear Agency is the basic step to enhance and improve the Quality Management System (QMS) for processes and laboratories that involve customers and suppliers in delivering products and services. The effectiveness of QMS is monitored by Research and Innovation Management Centre (RIMC) to ensure that all activities related to audit such as Internal Audit are well organized and implemented as documented in quality manual and procedure. This paper will discuss the status of internal audit for processes that implement MS ISO 9001 and laboratories that accredited with MS/ ISO IEC 17025 in year 2008, 2009 and 2010. The total of non-conformance (nc) and opportunity for improvement (ofi) for processes and laboratories and their numbers as per clause in MS ISO 9001 and MS ISO/ IEC 17025 are the indicators that reflects the effectiveness of QMS. Then, the total effectiveness of QMS for MS 9001 and MS ISO/ IEC 17025 is also determined via the number of conformance clause versus non-conformance clause for those three years. (author)

    1976-01-01

    The history, objectives, structures and functions of the International Electrotechnical Commission (IEC) and the International Organisation for Standardisation (ISO) are summarized. The IEC is affiliated to the ISO as its electrical division, but has technical and financial autonomy. Member countries of the EEC may be committed to the adoption of their formal agreements ('Standards') if these become incorporated as Directives. The national standardisation organisations, such as BSI in the U.K., form national committees and are responsible for submitting to the IEC the co-ordinated national viewpoints on particular subjects. The overall links between the technical committees and sub-committees of the ISO, IEC and BSI in the field of radiological protection are tabulated, and the relevant International Standards produced, or in the course of preparation, by the appropriate committees of the ISO and the IEC are listed. The bulk of the effort of the BSI committees is now aimed at the production of acceptable international standards. Compatible national standards then follow. This policy is in contrast to the earlier initial emphasis on national standards, and the improved international collaboration has had two welcome effects. The selection of proposals for standards is more critical, and compatibility with the relevant ICRP and ICRU publications is almost a prerequisite for any international standard. (U.K.)

    2008-07-01

    The International Electrotechnical Commission (IEC) 61850 standard is the reference communication protocol for all electrical substations protection and control systems. It creates models of all the elements and functionalities of an electrical substation, including physical elements such as switches or circuit breakers, as well as protection, control and monitoring functionalities. Network managers need to renew power substation automation and control systems in order to improve the efficiency and quality of services offered by electric utilities. Selta has proposed a new integrated solution for the automation of power substations which is fully compliant with the IEC 61850 norms. The solution involves the integration of control, automation, protection, monitoring and maintenance functions and applies leading edge technology to its systems, particularly for the TERNA network. The system is based on the use of many electronic devices at a power plant, each one with a specialized function, and all interconnected via a Station LAN. This solution, was tested on the TERNA network in Italy, in VHV and HV stations. It was shown to offer many advantages, such as an architecture based on full interoperability between control, monitoring and protection equipment; centralized and distributed automation; a LAN station that allows full interoperability between different bay units and protection relays in order to integrate equipment from various suppliers; the integration of automation systems in existing bay units and protection relays equipped with standard communication buses or with proprietary interfaces; and time synchronization for the entire system through a station GPS reception system. 10 refs., 1 tab., 7 figs.

    This report describes the work of standardization in the electrotechnical area and collaboration in selected committees of SEK, IEC and CENELEC. Electrotechnical standardization is traditionally an area characterized of large international collaboration, cooperation between government agencies, manufacturers and users. Standardization work has previously been a natural part of power companies' activities related to the extensive expansion activities, own construction business and to generally maintain a good knowledge base of staff. Taking part in the establishment of standards have been a good way to ensure long-term approach made in investments and a guarantee of open competition between manufacturers. Maintenance efforts have also been reduced by using established standards. The acceleration of technological progress has, however, increased pressure on standardization organizations, committee work etc. to keep up with time before the de facto standards have been applied in excessive degree. Reregulation of the electricity market in Sweden has also led to a difference in the standardization process. An increasing number of experts who have worked with standards is currently located at power companies consultancy activities. What was once a natural part of the power companies' internal skills provision today are exposed to a commercial assessment. In 1994 Elforsk was appointed by the owners the task of coordinating the power companies' joint standardization work within specifically electrical engineering. After an initial assessment of the activities was decided that remunera would be paid to the members in SEK, IEC and CENELEC who either participated in selected projects with international character or was either secretary or chairman of the Swedish technical committees (SEK)

    Complete test of publication follows. Purposes. Technical Committee TC62 of International Electrotechnical Commission (IEC) deals with medical electrical equipment (i.e. medical devices using electricity). Standardization concerning diagnostic radiology equipment is task of its Sub-Committee SC62B. An outlook of its activities and present situation, and especially of radiation protection aspects, is given. Materials and methods. Third edition of basic safety standard for medical electrical equipment IEC 60601-1 was issued in 2005. Elaboration of new collateral and particular standards - applicable together with it - is in progress. These standards are generally at the same time also European - EN - and national standards. There is a great importance of radiation protection in diagnostic X-ray equipment. Collateral standard IEC 6060-1-3 about it was at first issued in 1994. Rapid development of imaging technology demands updating of requirements. SC62B in 2003 founded a maintenance team MT37 for preparation of the second edition of this standard. According to new safety philosophy of IEC all modality specific requirements are to be collected in 'safety and essential performance' particular standards. A new working group WG42 - founded in 2006 - elaborates a new particular standard IEC 60601-2-54 for radiographic and radioscopic equipment. Maintenance team MT32 deals with safety and performance standards for X-ray tube assemblies. The authors actively participate in these activities. Results and discussion. Present and future system of diagnostic radiology IEC standards and some interesting details are presented. Conclusions. International standards - although they are not 'obligatory' - are generally the basis of safety and performance certification of diagnostic radiology equipment and often also of their quality assurance.

    1996-01-01

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

    This work presents a methodology for the X radiation qualities characterization following the new recommendations of the standard 61267 of the International Electrotechnical Commission (IEC) to establish a new procedure for calibration of dosimetric systems used in the field of diagnostic radiology. The reference qualities radiation of IEC 61267: RQR 2 to RQR 10, RQA 2 to RQA 10, RQB 2 to RQB 10 and RQN 2 to RQN 10 were implanted at the calibration laboratory of IPEN (LCI). Their characteristics were analyzed through measurements of beam parameters such as: Practical peak voltage (PPV), specific additional filtrations for each qualities (high purity aluminum of about 99.9%), 1st and 2nd Half Value Layers, homogeneity coefficient. The inherent filtration of the X ray tube was also determined. With the establishment of these radiation qualities, the LCI will be ready to calibrate the measuring instruments of radiation in the new qualities, allowing an improvement in radiological services offered by IPEN.

    Full Text Available Considerable efforts are currently being made by several international working groups focused on the development of generic, also known as simplified or standard, wind turbine models for power system stability studies. In this sense, the first edition of International Electrotechnical Commission (IEC 61400-27-1, which defines generic dynamic simulation models for wind turbines, was published in February 2015. Nevertheless, the correlations of the IEC generic models with respect to specific wind turbine manufacturer models are required by the wind power industry to validate the accuracy and corresponding usability of these standard models. The present work conducts the validation of the two topologies of variable speed wind turbines that present not only the largest market share, but also the most technological advances. Specifically, the doubly-fed induction machine and the full-scale converter (FSC topology are modeled based on the IEC 61400-27-1 guidelines. The models are simulated for a wide range of voltage dips with different characteristics and wind turbine operating conditions. The simulated response of the IEC generic model is compared to the corresponding simplified model of a wind turbine manufacturer, showing a good correlation in most cases. Validation error sources are analyzed in detail, as well. In addition, this paper reviews in detail the previous work done in this field. Results suggest that wind turbine manufacturers are able to adjust the IEC generic models to represent the behavior of their specific wind turbines for power system stability analysis.

    2015-06-15

    The International Electrotechnical Commission (IEC) writes standards that manufacturers of electrical equipment must comply with. Medical electrical equipment, such as medical imaging, radiation therapy, and radiation dosimetry devices, fall under Technical Committee 62. Of particular interest to medical physicists are the standards developed within Subcommittees (SC) 62B, which addresses diagnostic radiological imaging equipment, and 62C, which addresses equipment for radiation therapy, nuclear medicine and dosimetry. For example, a Working Group of SC 62B is responsible for safety and quality assurance standards for CT scanners and a Working Group of SC 62C is responsible for standards that set requirements for dosimetric safety and accuracy of linacs and proton accelerators. IEC standards thus have an impact on every aspect of a medical physicist’s job, including equipment testing, shielding design, room layout, and workflow. Consequently, it is imperative that US medical physicists know about existing standards, as well as have input on those under development or undergoing revision. The structure of the IEC and current standards development work will be described in detail. The presentation will explain how US medical physicists can learn about IEC standards and contribute to their development. Learning Objectives: Learn about the structure of the IEC and the influence that IEC standards have on the design of equipment for radiology and radiation therapy. Learn about the mechanisms by which the US participates in the development and revision of standards. Understand the specific requirements of several standards having direct relevance to diagnostic and radiation therapy physicists.

  16. Draft I.E.C. standard for monitoring PWR internal structures; Projet de norme C.E.I. pour la surveillance des structures internes des REP

    Energy Technology Data Exchange (ETDEWEB)

    Trenty, A.

    1994-06-01

    EDF has proposed to the International Electrotechnical Commission a draft standard for monitoring the vessel internal structures of PWRs. The standard applies to systems used for monitoring the vibratory behavior of the internal structures of PWRs (core barrel, thermal shield, fuel assemblies) on the basis of neutron fluctuations observed outside the vessel as well as of vessel vibrations. It covers the systems characteristics and the monitoring procedures. It should facilitate standardization of monitoring and comparisons on an international level. This paper presents the main features of the draft standard: -principles of measurement: correlation between movements of internals and ex core neutron noise on the one hand, forced vibrations of the vessel on the other hand; -sampling and conditioning of the signals; -monitoring equipment and in particular spectral analysis device; -functions of the monitoring software used for spectral analysis, peak detection and calculation of structure displacement; -studies preliminary to setting up the monitoring (calculation of internal vibratory modes, defect simulation on mockup, qualification on reactor during hot test...); -monitoring procedures (periodicity of analysis and what to do in case of anomaly); -documentation necessary to the monitoring. A diagnostic procedure is given as an example. The draft standard, written in 1994, will be presented in Frankfurt (Germany) in February 1995. (author). 1 annexe.

  17. Electrotechnical prospects for superconducting applications

    Science.gov (United States)

    Brunet, Y.; Renard, M.

    After a review of the classical limitations, due to iron and copper losses, we give the necessary superconducting properties, needed to achieve significant progresses, either in the size, or in the efficiency of electrotechnical plants. The successive achievement in SC will be explained, in relation with the physics of usual SC, and the needed properties for technology. The problems encountered in electrotechnics by decreasing interest are : networks losses and stability, storage of energy production, transformation and protection. In each case, SC solutions may be found or at least imagined. We shall review the limitations estimated in each case, generally by extrapolation of small scale experiments, with 4 K SC, and try to see what are the modifications which may be obtained by the use of high Tc SC. Special attention will be paid to energy storage and electrical machinery and the interest of completely superconducting plants will be shown. Une fois précisées les limitations actuelles des matériels électriques imposées essentiellement par l'utilisation de matériaux comme le fer ou le cuivre, nous détaillons les caractéristiques des supraconducteurs susceptibles d'améliorer les performances des installations électrotechniques. Les progrès successifs des conducteurs supraconducteurs sont expliqués en tenant compte de leur impact technologique. Les problèmes rencontrés en électrotechnique sont : les pertes et la stabilité des réseaux, le stockage et la production de l'énergie. Dans chaque cas des solutions supraconductrices existent ou peuvent être imaginées. Nous examinons notamment pour les machines électriques et le stockage de l'énergie, les solutions qui existent ou sont en cours de développement avec des supraconducteurs à basse température (˜ 4 K) et quelles sont les modifications apportées par l'utilisation de supraconducteurs à haut Tc.

  18. Qualification of a Human-System Interface to Meet IEC 61513

    Malcom, Scott; Kim, Sun Ho; Macdonald, Marienna

    2011-01-01

    This paper describes the steps Atomic Energy of Canada Limited (AECL TM ) undertook to qualify its Advanced Control Centre Information System (ACCIS TM ) to meet the requirements of IEC 61513. It will address the different strategies used for software versus hardware. As well, the paper will discuss the steps that have been taken to qualify third-party commercial-off-the-shelf products that are used in conjunction with a qualified product. ACCIS is a display, monitoring and supervisory control system that is designed to be readily configurable and scalable to satisfy the display requirements for single functions or complex industrial plant systems. The ACCIS software services are configured and deployed across a distributed computing environment to meet the needs of a given implementation. From small single-node applications to large, complex, multi-node configurations, system behaviour is largely configured via data specifications. This design reduces the costs associated with development of custom software and allows the user to have greater control of behavioral attributes of the system, including data sampling and storage rates, the appearance and behaviour of displays, alarm annunciation features, and the configuration of system health checks. Utilities and regulators are demanding that these computer-based systems are developed and maintained with an appropriate amount of engineering rigor. To meet this challenge, AECL is qualifying its ACCIS HSI, which is intended for use in all future CANada Nuclear Deuterium (CANDU TM ) nuclear power plants, to meet the requirements of the International Electrotechnical Commission's (IEC) standard for instrumentation and control systems important to safety, IEC 61513. Transitioning to the IEC standards has not been without its challenges. While AECL previously used a software development model very similar to the IEC model, absorbing the volume of the IEC standards and understanding how they should be applied has been

    The IEC, founded in 1906, is an independent international standards organization. Its standardization work deals with almost all branches of electrotechnology in the electrotechnical, electronical and data-processing field, covering all applications, as for example telecommunications and nuclear energy. The IEC Central Office is situated in Geneva (Switzerland). The Technical Committee No. 45 was set up in 1960 at the IEC general meeting in New Delhi, with the scope as given in the IEC Directory. Its revised scope is under consideration in the Committee of Action of the IEC and reads: ''To prepare international standards relating to electrical and electronic equipment and systems specific to nuclear applications''. The chart shows the organigram of the Technical Committee which comprises about 75 experts in the nuclear field from about 20 industrial countries. We can see here the standard diagram of a Technical Committee with its Sub-committees and Working Groups. The meetings are held in a member country at the request of its National Committee. One shows the places of the plenary meetings of TC 45 as well as the meetings of its Sub-committees and their Working Groups held till now. The Technical Committee 45 has in addition to its seven Working Groups also two Sub-committees having several further Working Groups of their own. The Sub-committee 45 A ''Reactor Instrumentation''. The Sub-committee 45 B ''Radiation protection instrumentation''. Till now TC 45 has published about 85 standards. Regarding work in preparation, one shows the present and future work within the Technical Committee and its Sub-committees. Impact of works and liaisons is briefly discussed [fr

    This standard is applicable to portable, transportable or installed assemblies intended to measure environmental air kerma rates from 30 nGy h -1 to 10 μGy h -1 (3 μrad h -1 to 1 mrad h -1 ) due to X or gamma radiation of energy between at least 50 keV and 1.5MeV * . If the assembly is to be used to measure air measure air kerma rates in the area surrounding a nuclear reactor producing 6 MeV radiation it will be necessary to determine the response at this energy. For the purpose of radiation protection these assemblies comprise at least: - a detection sub-assembly (e.g. ionization chamber, GM counter tube, scintillation detector, etc.); - a measuring sub-assembly including a display device, which may be connected together either rigidly or by means of a flexible cable or incorporated into a single assembly. The installed assembly may also comprise a continuous recorder (e.g. chart or magnetic cassette recorder or telemetry equipment). The requirements of this standard are also applicable to assemblies that use integration of ionization current, count-rate, etc. to enable a mean air kerma rate to be indicated or determined. For the assemblies described above, this standard specifies general characteristics, general test procedures, radiation characteristics, electrical, mechanical, safety and environmental characteristics as well the identification certificate. Assemblies that indicate air kerma from integration of the detector's signal will be dealt with in the future IEC Publication 1017-2. This standard does not apply to thermoluminescence dosimetry systems or other passive integrating devices. This standard does not provide for the measurement of beta radiation

    1999-01-01

    In recent years there has been increased interest, and even need, amongst laboratories performing measurements of radionuclides to obtain accreditation. It has been discussed how this could be achieved with maximum flexibility for the laboratories and with minimum effort. The issuing of a new draft international standard, the ISO/IEC DIS 17025, created speculations whether it could offer a new and better way for laboratories to obtain accreditation. It was decided within the NKS/BOK-1.1 project to explore possible options for obtaining accreditation and what possibilities the new standard could offer. The benefits of computerised document control systems were also explored. The results were reported at the 12th Annual Meeting of the Nordic Society for Radiation Protection, 23-27 August 1999. Since then the final version of the standard has been published. The voting will continue until November 16th 1999 and is not clear at present whether the standard will be accepted or not. The original version of this paper was updated to reflect these recent developments. (au)

    The purpose of the present study was to determine the Detective Quantum Efficiency (DQE) of CMOS imaging detectors, coupled to structured CsI:Tl and Gd_2O_2S:Tb scintillating screens, following the new IEC 62220-1-1:2015 International Standard. DQE was assessed after the experimental determination of the Modulation Transfer Function (MTF) and the Normalized Noise Power Spectrum (NNPS) in the general radiography energy range. Two CMOS sensors were used; one with a pixel size of 22.5 μmcoupled to a columnar CsI:Tl scintillator screen with thickness of 490 μm, which was placed in direct contact with the optical sensor and one with a pixel size of 74.8 μmcoupled to a 200 μmcolumnar CsI:Tl scintillator screen. The MTF was measured using the slanted-edge method (following both the IEC 62220-1:2003 and IEC 62220-1-1:2015 methods) while NNPS was determined by 2D Fourier transforming uniformly exposed images. Both parameters were assessed by irradiation under the RQA-3 and RQA-5 (IEC 62220-1-1:2015) beam qualities. The detector response functions were linear for the exposure ranges under investigation. MTFs calculated following the 62220-1:2003 protocol, were found in all cases overestimated in the higher frequency range (spatial frequencies higher than 2 cycles/mm). DQE values, determined with the IEC 62220-1:2003 method, were also found overestimated (spatial frequencies higher than 2 cycles/mm), due to the influence of both MTF and NNPS. The influence of both additive and multiplicative lag effects were found below 0.005, insuring that lag contributes less than 0.5% of the effective exposure. - Highlights: • DQE was measured with the novel 62220-1-1:2015 protocol and compared to 62220-1:2003. • Two CMOS sensors were evaluated. • DQE of the 62220-1:2003 was overestimated due to the addition of noise when averaging MTFs.

    In the chapters on electrotechnics, the necessary fundamentals are presented and illustrated by a few examples, and the logical structure of electrotechnics is made visible. The extensive material is thus summarized, and students are invited to make the abstractions which are necessary. In the part on electrotechnics in practice, applications of electrotechnics are discussed in detail. This part of the book will be particularly valuable for practical training. In the materials science section, the subjects discussed at this teaching level are presented with a special view to electrotechnics. Attention is paid to the increasing importance of materials technology in view of the decline in raw material resources. Materials science will not be continued in the next part.

  12. A quality assurance system for personal monitoring in Ireland: experience to date and transition from EN 45001 to ISO/IEC 17025

    International Nuclear Information System (INIS)

    Currivan, L.; Spain, D.; Rafferty, B.

    2002-01-01

    Up to 2000 the RPII was the competent authority for approval of dosimetry services operating within Ireland. However the transposition into Irish Law of Council Directive 96/29 Euratom in May 2000 means that dosimetry services operating in Ireland must now attain accreditation to the standard of EN-45001 or its equivalent. To comply with this new legislation the RPII sought accreditation for the Dosimetry Service from the Irish National Accreditation Board (NAB). In accordance with the EN-45000 series of European Standards and the relevant ISO guides NAB tests accuracy of results and accredits organisations as appropriate. In September 2000 accreditation was granted to the Dosimetry Service for individual monitoring of personnel who are occupationally exposed to ionising radiation. The scope of the accreditation covers the evaluation of personal doses, for photon and beta, using TLD. Frequent internal quality audits, together with periodic inter-laboratory test programmes, ensure that these quality standards are maintained. This accreditation fulfils the approval under legislation for dosimetry services. The new standard, ISO/IEC 17025, was introduced by ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) in 1999. This standard was introduced in Ireland by NAB and will be implemented for future assessments. The aim of this paper is to describe the quality system currently operated by the RPII's Dosimetry Service, our practical experience to date, and to outline the transition from EN-45001 to ISO/IEC 17025

  13. The suitability of the IEC 61400-2 wind model for small wind turbines operating in the built environment★

    Evans Samuel P.

    2017-01-01

    Full Text Available This paper investigates the applicability of the assumed wind fields in International Electrotechnical Commission (IEC standard 61400 Part 2, the design standard for small wind turbines, for a turbine operating in the built environment, and the effects these wind fields have on the predicted performance of a 5 kW Aerogenesis turbine using detailed aeroelastic models developed in Fatigue Aerodynamics Structures and Turbulence (FAST. Detailed wind measurements were acquired at two built environment sites: from the rooftop of a Bunnings Ltd. warehouse at Port Kennedy (PK (Perth, Australia and from the small wind turbine site at the University of Newcastle at Callaghan (Newcastle, Australia. For both sites, IEC 61400-2 underestimates the turbulence intensity for the majority of the measured wind speeds. A detailed aeroelastic model was built in FAST using the assumed wind field from IEC 61400-2 and the measured wind fields from PK and Callaghan as an input to predict key turbine performance parameters. The results of this analysis show a modest increase in the predicted mean power for the higher turbulence regimes of PK and Callaghan as well as higher variation in output power. Predicted mean rotor thrust and blade flapwise loading showed a minor increase due to higher turbulence, with mean predicted torque almost identical but with increased variations due to higher turbulence. Damage equivalent loading for the blade flapwise moment was predicted to be 58% and 11% higher for a turbine operating at Callaghan and PK respectively, when compared with IEC 61400-2 wind field. Time series plots for blade flapwise moments and power spectral density plots in the frequency domain show consistently higher blade flapwise bending moments for the Callaghan site with both the sites showing a once-per-revolution response.

    2005-01-01

    On 18 December 2004, the President of the Swiss Electro-technical Committee, Martin Reichle (left), presented the award to Helmut Schönbacher. Helmut Schönbacher, of the Safety Commission at CERN, has received, the "1906 Award" of the International Electrotechnical Commission (IEC) for his standardisation work on the influence of ionizing radiation on insulating materials. From 1986 until 2004, Schönbacher was leader of a working group on radiation composed of internationally recognised experts. It edited standards of the IEC 60544 series on the determination of the effects of ionizing radiation on electrical insulating materials.

    At medium- and high-head hydropower plants (HPPs) on sediment-laden rivers, hydro-abrasive erosion on hydraulic turbines is a major economic issue. For optimization of such HPPs, there is an interest in equations to predict erosion depths. Such a semi-empirical equation suitable for engineering practice is proposed in the relevant guideline of the International Electrotechnical Commission (IEC 62364). However, for Pelton turbines no numerical values of the model's calibration parameters have been available yet. In the scope of a research project at the high-head HPP Fieschertal, Switzerland, the particle load and the erosion on the buckets of two hard-coated 32 MW-Pelton runners have been measured since 2012. Based on three years of field data, the numerical values of a group of calibration parameters of the IEC erosion model were determined for five application cases: (i) reduction of splitter height, (ii) increase of splitter width and (iii) increase of cut-out depth due to erosion of mainly base material, as well as erosion of coating on (iv) the splitter crests and (v) inside the buckets. Further laboratory and field investigations are recommended to quantify the effects of individual parameters as well as to improve, generalize and validate erosion models for uncoated and coated Pelton turbines.

  17. On the Implementation of the IEC 61850 Standard: Will Different Manufacturer Devices Behave Similarly under Identical Conditions?

    Full Text Available Standardization in smart grid communications is necessary to facilitate complex operations of modern power system functions. However, the strong coupling between the cyber and physical domains of the contemporary grid exposes the system to vulnerabilities and thus places more burden on standards’ developers. As such, standards need to be continuously assessed for reliability and are expected to be implemented properly on field devices. However, the actual implementation of common standards varies between vendors, which may lead to different behaviors of the devices even if present under similar conditions. The work in this paper tested the implementation of the International Electro-technical Commission’s Generic Object Oriented Substation Event GOOSE (IEC 61850 GOOSE messaging protocol on commercial Intelligent Electronic Devices (IEDs and the open source libiec61850 library—also used in commercial devices—which showed different behaviors in identical situations. Based on the test results and analysis of some features of the IEC 61850 GOOSE protocol itself, this paper proposes guidelines and recommendations for proper implementation of the standard functionalities.

    Participants of the IEC Workshop for the Production of OHP Material on Reproductive Health for Adolescents and Young Adults held November 25-30 in Japan developed innovative, visually appealing overhead projector (OHP) transparencies to serve as prototype information, education, and communication (IEC) materials for the Asian Region. The materials cover a wide range of topics from early marriage to unwanted pregnancy. This paper briefly describes the prototypes. One group focused upon early marriage, an issue of considerable importance to the health and welfare of young women in countries such as Bhutan, India, and Nepal. Participants from China, Laos, Malaysia, and Thailand focused upon the issue of gender equality, while a third group developed OHP material to teach a range of issues related to young people's sexual and reproductive health. Finally, the fourth group, drawn from Indonesia, the Philippines, and Vietnam, focused upon the topic of menstruation with a prototype targeted to boys and girls aged 9-14 years. Boys were included to foster their understanding of menstruation as a natural phenomenon.

    In their position as centres for expertise in radiation dosimetry and its applications, the Secondary Standard Dosimetry Laboratories (SSDLs) are expected to advise the radiation users, the radiotherapy centres in particular, in selection and use of the most suitable dosimetric equipment. Various dosimeters are commercially available, but objective information on their fundamental technical characteristics is lacking. Such information would be valuable and necessary for the SSDLs to be able to judge the accuracy and reliability of the many choices which exist for a given application. The results of systematic evaluations of dosimeters in a recognized SSDL (or SSDLs) could be helpful supplementary information to the other SSDLs and to the radiation users. In 1983 The Finnish Centre for Radiation and Nuclear Safety (STUK; old name: Institute of Radiation Protection) and the International Atomic Energy Agency (IAEA) made a research contract, the purpose of which was to test selected dosimeters for use in radiotherapy in accordance with the specifications by the International Electrotechnical Commission (IEC)

    Since radiation of a laser diode (LD) is quite different from that of a light emitting diode (LED), evaluating their safety under one and the same standard (criterion) is questionable. The International Electrotechnical Commission (IEC), however, treats them in the same way. For the remedy of such contradiction and for the clarification of difference between the two devices in terms of radiation characteristics, they were quantitatively measured for spatial coherence and further measured for coherence dependency of their beam diameters. Well-supported threshold levels were prepared and biological tests were conducted for proposing a revision of the LED safety standard (IEC). As for the safety of equipment with built-in infrared devices, a measurement method was prepared as IEC61913 and devices are already at the CVD (chemical vapor deposition) stage. The result will be placed before the IEC/TC76 committee for deliberation of IEC60825-1 revision. Furthermore, to establish alignment between IEC and ISO (International Standardization Organization) in terms of laser-aided measurement which is the foundation for such committee deliberation, an ISO/IEC international joint group was created, and a technical recommendation was compiled and presented to the two standardizing organizations.

  6. Using the IEC standard to describe low-background detectors -- What can you expect?

    International Nuclear Information System (INIS)

    Keyser, R.M.; Wagner, S.

    1998-01-01

    Many measurements for environmental levels of the radioactive content require that the gamma-ray detector be low background, that is, free of any radioactive content. This is, of course, not possible, but the radioactivity in the detector must be reduced to as low a value as possible. The description or specification of the background spectrum necessary to achieve the desired results is needed. The new International Electrotechnical Commission (IEC) standard for describing the background makes the specification of the background in a high-purity germanium (HPGe) detector simple, unambiguous, and related to how the detector will be used. Users and manufacturers will finally be speaking the same language on this subject. Because this standard extends the specification of the performance of an HPGe detector, there is little history available for comparison and thus no means of determining a good value. To develop a history, the background spectrum for 500 low-background HPGe ORTEC detectors were all counted in similar low-background shields. These detectors were in a variety of mechanical cryostat and endcap configurations. The continuum background is a function of energy and detector size/configuration. The peak area for the peak energies listed in the standard is a function of detector size and configuration. The results thus give practical guidance for obtaining the most appropriate low-background detector for a specific measurement problem

CIEMAT Internal Dosimetry Service (IDS) has developed and implemented a quality system based on ISO/IEC 17025 to ensure compliance with the general requirements of this reference standard. The development of documentary support according to this quality system permitted to standardise the systematic activities performed within the whole body counter and in vitro bioassay laboratories as well as the procedures carried out by qualified staff in charge of internal dose assessment. There was no previous experience in the accreditation of other internal dosimetry services in Spain. Then, requirements from the national regulatory body (Nuclear Safety Council, CSN) and national accreditation entity (ENAC) have been considered. The main concerns were to guarantee the traceability in the whole process and to avoid possible charge of interpretation or subjectivity in the methodology of dose assessment due to intakes of radionuclides when calculating from monitoring data.

    Inertial Electrostatic Confinement (IEC) is one of the earliest plasma confinement concepts, having first been suggested by P. T. Farnsworth in the 1950s. The concept involves a simple apparatus of concentric spherical electrostatic grids or a combination of grids and magnetic fields. An electrostatic structure is formed from the confluence of electron or ion beams. Gridded IEC systems have demonstrated neutron yields as high as 2 * 10 10 neutrons/sec. These systems have considerable potential as small, inexpensive, portable neutron sources for assaying applications. Neutron tomography is also a potential application. Atomic physics effects strongly influence the performance of all of these systems. Important atomic effects include elastic scattering, ionization, excitation, and charge exchange. This paper discusses how an IEC system is influenced by these effects and how to design around them. Theoretical modeling and experimental results are presented

    The UNFPA-supported project on development and distribution of information, education, and communication (IEC) materials in support of improving women's health and status was evaluated at a workshop held in Tokyo in December 13-15, 1995. The 1992-95 cycle of the project was analyzed by experts from Bangladesh, China, India, Indonesia, Malaysia, Nepal, the Philippines, and Vietnam plus three experts from the UNFPA/Country Support Team. The workshop also made it possible for the experts to identify needs as well as effective utilization of existing IEC materials. It was suggested that a nongovernmental organization be established for the distribution and effective use of these materials. The workshop mostly reviewed the print and audiovisual materials. Videos were also evaluated. The materials were found useful for the targeted region. Among other subregional issues it was noted that youth needs were inadequately addressed as they related to sexually transmitted diseases (STDs), unwanted pregnancy, risk of maternal mortality and morbidity, low birth weight, and premature birth. Although the women of the region comprise one-third of the world's population, 70% of the global annual maternal mortality of 500,000 occurs in the subregion. IEC materials should also target adolescents and their support groups. Other needs were also outlined: the expansion of educational opportunities for women, the promotion of employment, the involvement of men, and the training of personnel. The strategies used in the cycle helped strengthen self-reliance through information and experience sharing. The focus on women should be continued with more attention paid to adolescents and young adults, including males. Women's health issues should be expanded to include menopause, reproductive tract infections, STDs, HIV/AIDS prevention, and legal rights including abortion. The production of IEC materials should be identified through research and analysis of existing materials, focus group

    Research and development was carried out for the enhancement of logical format-based interoperability between optical disk systems for the purpose of presenting propositions for international standards. That is, UDF (universal disk format) defined by OSTA (Optical Storage Technology Association) was taken up against the volume/file structure defined by ISO/IEC13346, and efforts were exerted to substantiate environments for its compatibility test and to develop specifications to achieve such enhanced interoperability. In this fiscal year, specifications were drafted for application program interfaces for the UDF-based file system and UDF security augmentation. These would be presented to IEC (International Electrotechnical Commission) and OSTA, respectively. Their Japanese versions were submitted to the Ministry of Economy, Trade and Industry of Japan, for publication as standard-related information. Maintenance of UAF (universal accessible file) system-compliance test tools were accomplished in response to user requirements and to the updating of UDF-compliance test disk specification. (NEDO)

    Full text: An International Standard is a document, established by consensus and approved by a recognized body that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context. As such, it is a mechanism for sharing knowledge in a particular field. The consensus process used to approve the content of standards ensures that the content is essentially peer-reviewed. This presentation will explain how International Standards are developed and used and their importance in the dissemination of scientific and engineering information. It will also explain the role of the IEC in ensuring that the process for developing standards meets the core principles of the Code of Good Practice of the WTO TBT agreement: transparency, openness, impartiality and consensus, effectiveness and relevance, coherence, and addressing the concerns of developing countries.

    2001-01-01

    This presentation provided some basic information regarding standards and the International Organization for Standardization (ISO). It also explained the importance of standardization activities, particularly ISO/TC 197 which applies to hydrogen technologies. Standards are established by consensus. They define the minimum requirements that will ensure that products and services are reliable and effective. Standards contribute to the elimination of technical barriers to trade (TBT). The harmonization of standards around the world is desirable in a free trade environment. The influence of the TBT on international standardization was discussed with particular reference to the objectives of ISO/TC 197 hydrogen technologies. One of the priorities for ISO/TC 197 is a hydrogen fuel infrastructure which includes refuelling stations, fuelling connectors, and storage technologies for gaseous and liquid hydrogen. Other priorities include an agreement between the International Electrotechnical Commission (IEC) and the ISO, in particular the IEC/TC 105 and ISO/TC 197 for the development of fuel cell standards. The international standards that have been published thus far include ISO 13984:1999 for liquid hydrogen, land vehicle fuelling system interface, and ISO 14687:1999 for hydrogen fuel product specification. Standards are currently under development for: liquid hydrogen; airport hydrogen fuelling facilities; gaseous hydrogen blends; basic considerations for the safety of hydrogen systems; gaseous hydrogen and hydrogen blends; and gaseous hydrogen for land vehicle filling connectors. It was concluded that the widespread use of hydrogen is dependent on international standardization

    The application of hydrogen and fuel cells has expanded as the technology in international markets has improved. Leading countries have focused on establishing hydrogen and fuel cell technology standards. Both the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) continuously release new hydrogen and fuel cell related standards. Although the government of Taiwan is promoting the development of a hydrogen and fuel cell industry, it may delay the commercialized schedule if there are no hydrogen and fuel cell related standards and regulations in place. Standards and regulations must be established as quickly as possible in order to accelerate the progress of the hydrogen and fuel cell industry. This presentation reviewed the international progress in hydrogen and fuel cell development and explained Taiwan's response strategies regarding the adoption of hydrogen and fuel cell products in niche Taiwanese markets

    The International Commission on Radiological Protection (ICRP) has recommended to lower the limit of the dose to the eye lens for occupationally exposed persons to a mean value of 20 mSv y -1 (averaged over 5 y, with a maximum of 50 mSv y -1 ); already in the autumn of 2011, both the European Commission and the International Atomic Energy Agency (IAEA) took over this reduction in their respective draft basic safety standards. Even prior to this (and since then, increasingly so), several international activities were started (among other things, the following ones): (1) the ICRP adopted a stylised model of the eye to calculate dose conversion coefficients for its report ICRP 116; (2) the European Commission has funded the ORAMED project dealing with radiation protection in medicine; (3) in its standard IEC 62387 on passive dosimetry systems, the International Electrotechnical Commission (IEC) has laid down requirements for Hp(3) eye dosemeters; (4) the International Organization for Standardization (ISO) and the IAEA provide a range of practical advice in the standard ISO 15382 (still a draft) and in a technical document IAEA TecDoc on both radiation protection and on dosimetry; (5) for most cases, the International Commission on Radiation Units and Measurements (ICRU) recommends both phantoms (the slab and the cylinder). In short: most national procedures can orientate themselves on international ones; some questions, however, remain open. (authors)

    2016-01-01

    An IEC 61850 packet generator is used to produce IEC 61850-9-2 packets by simulating the merging unit and testing the IEC 61850 digital device. While the existing IEC packet generator can produce ideal digital without any noise, it does not take into account the fact that the merging unit output signal packets will be inevitably superimposed with noise. Since the International Electrical Commission standard of the electronic current transformer specifies the minimum output signal-to-noise ratio of the merging unit to be 30 dB, and the signal superimposed with noise will influence the operation performance of the digital device, it is necessary to design a multi-function IEC 61850-9-2 packet generator for a digital device test. Therefore, in this paper, a multi-function IEC 61850 packet generator has been developed, which not only can output various IEC 61850-9-2 packets, but also can add white Gaussian noise to the signal for digital device testing. By testing three digital electricity meters from different manufacturers, we showed that the error of the digital electricity meter is significantly larger when the signal packet is superimposed with noise. Also when the signal-to-noise ration is 30 dB, the error of one of the meters exceeds the allowed range of the accuracy class. This indicates that the noise testing and the noise setting function of the system has an important role in the testing of a digital device. (paper)

    2014-05-01

    Full Text Available The electrotechnical industry is in the top branch within the industrial development and the technical progress, currently providing a wide range of innovative products and services, and as a result of this dynamic development, the electrotechnical industry has currently become a key industry for many other industrial sectors. Electricity has established itself in most areas of activity due to its easy use, easy distance transport, the fact that it can be turned into other forms of energy and because it is the most suitable for the supply of automation processes. Consequently, given that industry is the key factor for the recovery, modernization and economic revival of the country, we can say that the electrotechnical industry also has a crucial influence on Romania’s social and economic evolution, and this evolution is in its turn the result of the production cost monitoring and control in this sector.

    1993-01-01

    The thrust of this article is to define terms of IEC, IEC strategies, the stepwise planning process for IEC, data requirements, the ideational change process, and the need for situational and institutional analysis. A chart provided an at-a-glance perspective on the 11 steps in IEC strategic planning for as many specific target groups as needed. The steps are to state the goals, select and prioritize the target audience, describe the target audience,, determine the IEC activities, outline appropriate messages, identify communication channels, identify managerial and organizational strategies, calculate the amount of resources required, identify a realistic time frame, and evaluate critical factors and obstacles. IEC goals are to contribute to solving a problem or supporting an issue, which involved attitudinal and/or behavioral changes. Many strategies are possible. The common weaknesses are the lack of priorities, the view of targets as a mass audience, a lack in support for population strategies, a lack of integration with family planning or specific population sectors, a lack of integration of up-to-data research findings on population programs, vague or difficult-to-measure objectives, reliance on printed media, and sporadic assessment of personnel needs. THe levels of strategy are identified as follows: 1) national and multisectoral, 2) national and sectoral specific, and 3) project specific. Traditional sociocultural research and KAP surveys are not sufficient to provide an understanding of the target audience. There must be an understanding of the stages of individual change: unaware, aware, concerned, information seeking, learning, motivated to change, initial behavior change, sustained behavior change, and adoption or refusal of behavior change. Beliefs must be distinguished from attitudes in measurement. Changes in beliefs may involve correction of misinformation; attitude change requires a motivational approach. Behavior may be determined by other

    International Nuclear Information System (INIS)

    2007-01-01

    In 2005, the IAEA announced the establishment of a fully integrated Incident and Emergency Centre (IEC). The functions of the IEC include coordinating prompt assistance to requesting States in the case of a nuclear security incident. As the global focal point for international preparedness, communication and response to nuclear and radiological incidents or emergencies irrespective of their cause, the IEC stands at the centre of coordinating effective and efficient activities worldwide. The IEC's work includes the evaluation of emergency plans and assistance in their development. The Centre also develops accident classifications based on plant conditions and supports effective communication between neighbouring countries. In addition, it develops various response procedures and facilitates national exercises on response to reactor emergencies. This includes training a broad range of IAEA staff to respond to emergencies as well as training of external experts. Response to incidents and emergencies can involve the exchange of information, provision of advice and/or the coordination of field response. In order to coordinate a global response, the IEC hosts a Response Assistance Network (RANET) under which Member States, Parties to the Emergency Conventions and relevant international organizations are able to register their response capabilities. This network aims to facilitate assistance in case of a nuclear or radiological incident or emergency in a timely and effective manner. An important component of the global emergency response system is the notification and reporting arrangements and systems operated by the IEC. The IEC operates systems that are reliable and secure. Member States, Non-Member States and international organizations have historically reported events and requests for assistance to the IAEA through the ENATOM arrangements using the ENAC web site, phone or fax. Under these arrangements, States have nominated Competent Authorities and National Warning

    . This paper presents the results of the numerical simulations that reconstruct the processing of flickermeter in frequency domain. With the use of standard test signals, the characteristics of flickermeter were determined for the case of amplitude modulation of input signal, frequency modulation of input signal, and for input signal with interharmonic component. For the needs of simulative research, elements of standard IEC flickermeter signal chain as well as test signal source and tools for acquisition, archiving, and presentation of the obtained results were modeled. The results were presented with a set of charts, and the specific fragments of the charts were pointed out and commented on. Some examples of the influence of input signal’s bandwidth limitation on the flickermeter measurement result were presented for the case of AM and FM modulation. In addition, the diagrams that enable the evaluation of flickermeter’s linearity were also presented.

  17. Experience with nuclear safety standards development in non-governmental international organizations

    1985-01-01

    Besides the IAEA as a 'governmental' organization dealing with basic safety recommendations addressed primarily to the national regulatory bodies in developing countries, two closely related non-governmental international standards organizations have gained extensive experience in the field of nuclear standardization. Over more than 25 years since their formation, both (a) the International Organization for Standardization's (ISO) Technical Committee 85 'Nuclear Energy', in particular in its Sub-Committee 3 'Reactor Technology and Safety' and (b) the International Electrotechnical Commission's (IEC) Technical Committee 45 'Nuclear Instrumentation' have published numerous standards. A brief review is given of these, draft standards, and other documents planned to become international standards. Many of them deal with rather specialized topics typical for 'industrial' standards such as standardized procedures, instruments, methods, materials, test methods, terminology, and signs and symbols, but others are directly related to more basic safety issues. In some areas such as quality assurance, seismic aspects of siting and terminology, there has been in the past occasional overlap in the activities of the NUSS programme, IEC and ISO. Letters of Understanding have since 1981 contributed to clarifying the borderlines and to avoiding redundant efforts. Also, some experiences and problems are described arising, for example, from the harmonization of different national safety philosophies and traditions into universally accepted international standards, and the transfer of international standards into national standards systems. Finally, based on a recent comprehensive compilation of some 3300 nuclear standards and standards projects, an attempt is made to present a cost/benefit analysis and an outlook on future developments.

    Studies were made about methods for testing and evaluating plastic optical fiber (POF) for the purpose of submitting a proposition to IEC (International Electrotechnical Commission) for the methods to be internationally standardized. In this fiscal year, tests and analyses were conducted relative to the effects of the light source emission area size, wavelength, and axial displacement. Next, underfilled launch was studied from a practical viewpoint, and a method using a mode filter was proposed. Finally, round robin tests were conducted for each of the companies using overfilled launch and underfilled launch, and the reproducibility of measured values was grasped. In this fiscal year, a new study added, which involved a method for measuring structural parameters. Though POF was below standard as an object of IEC's gray scale method, yet it was found, thanks to the recently developed CCD (charge coupled device) cameras, that the method might also be applicable to POF. A groundwork plan was drafted on band test methods including the overfilled launch method toward international standardization. (NEDO)

    The Sysmex R-500 (R-500) Hematology Analyzer is a bench-top system appropriate for the analysis of limited batches of blood samples. The R-500 provides percentage proportional (RET%), absolute reticulocyte (RET#), and absolute red blood cell (RBC#) counts. The system was validated at the Doping Control Laboratory of Athens, according to the International Committee for Standardization in Hematology, International Standards Organization (ISO/IEC) 17025, and World Antidoping Agency (WADA) specifications. The instrument calibration was performed according to the manufacturer and validation parameters comprised linearity, precision, uncertainty (intermediate and long-term precision), comparability, effect of drift, carryover, stability, and accuracy. The linearity and the comparability studies for RET#, RET%, and RBC# were expressed in regression factors (R2) and coefficients of correlation [r(x, y)], respectively. For the precision studies, the coefficients of variation for RET#, RET%, and RBC# were 9.49%, 9.83%, and ISO/IEC 17025 and WADA specifications.

    This dossier gathers a series of short articles about energy security and efficiency in a context of policy transition. The first paper deals with the use of international standards to promote energy efficiency thanks to efficient public policies and private sector actions. This was the main topic of the mixed workshop organized by the International electrotechnics Commission (IEC) in spring 2009. The second paper presents the new strategic analysis of the European commission in the domain of energy which stresses on the '20-20-20' climate change proposals approved in December 2008. A new European action plan for energy security and solidarity defines 5 domains requiring an extra action to warrant a sustainable energy supply. The commission is also examining the challenges that Europe will have to face between 2020 and 2050. The third article treats of the security of natural gas supplies which represents a quarter of the European Union (EU) energy mix. The supply crises susceptible to occur may have serious economic and social consequences. Therefore, the EU must be prepared to warrant its security of supplies. Cogeneration allows the EU to stay close to its energy goals. Buildings play a key role in the realisation of the EU's energy saving objectives and fight against climate change. The new directive on buildings energy efficiency (2002/91/CE) will allow to exploit this potential of saving and to stimulate sustainable investment and employment as well. Finally, the publication of the second WBCSD (World business council for sustainable development) international report on buildings energy efficiency has led GDF Suez utility to reaffirm its commitment in favour of energy saving and efficiency.

    In 1995 the Technical Committee TC88 of the International Electrotechnical Commission decided to start a new work item, namely to prepare a standard for the certification procedures for wind turbines with respect to safety, performance, interaction with the public grid, environmental requirements and the documentation requested by the certification bodies. The purpose was to provide a common basis for certification of wind turbines, including a basis for accreditation of certification bodies and mutual recognition of certificates. A working group (WG9) was created to prepare a committee draft. WG9 submitted the result late in 1998 to TC88. This paper presents the committee draft Standard, which defines a certification system for Wind Turbine Generator Systems. Key issues in the evaluation of conformity with these standards and identified needs for other technical criteria and procedures are presented. (au) 10 refs.

    A cylindrical version of the single grid Inertial Electrostatic Confinement (IEC) device (termed the C-device) has been developed for use as a 2.5-MeV D-D fusion neutron source for neutron activation analysis. The C-device employs a hollow-tube type cathode with similar anodes backed up by ''reflector'' dishes. The resulting discharge differs from a conventional hollow cathode discharge, by creating an explicit ion beam which is ''pinched'' in the cathode region. Resulting fusion reactions generate ∼10 6 neutron/s. A pulsed version is under development for applications requiring higher fluxes. Several pulsing techniques are under study, including an electron emitter (e-emitter) assisted discharge in a thorated tungsten wire emitter located behind a slotted area in the reflector dishes. Pulsing is initiated after establishing a low power steady-state discharge by pulsing the e-emitter current using a capacitor switch type circuit. The resulting electron jet, coupled with the discharge by the biased slot array, creates a strong pulse in the pinched ion beam. The pulse length/repetition rate are controlled by the e-emitter pulse circuit. Typical parameters in present studies are ∼30micros, 10Hz and 1-amp ion current. Corresponding neutron measurements are an In-foil type activation counter for time averaged rates. Results for a wide variety of operating conditions are presented

    To address the standardization issues of perceptually based image quality for printing systems, ISO/IEC JTC1/SC28, the standardization committee for office equipment chartered the W1.1 project with the responsibility of drafting a proposal for an international standard for the evaluation of printed image quality1. An ISO draft Standard2, ISO/WD 19751-1, Office Equipment - Appearance-based image quality standards for printers - Part 1: Overview, Procedure and Common Methods, 2004 describes the overview of this multi-part appearance-based image quality standard. One of the ISO 19751 multi-part Standard"s tasks is to address the appearance-based gloss and gloss uniformity issues (in ISO 19751-2). This paper summarizes the current status and technical progress since the last two updates3, 4. In particular, we will be discussion our attempt to include 75 degree gloss (G75) objective measurement5 in differential gloss and within-page gloss uniformity. The result for a round-robin experiment involving objective measurement of differential gloss using G60 and G75 gloss measurement geometry is described. The results for two perceptual-based round-robin experiments relating to haze effect on the perception of gloss, and gloss artifacts (gloss streaks/bands, gloss graininess/mottle) are discussed.

    Information security has gained tremendous importance for energy automation systems over the last years. New standards like IEC 62351 address this topic and specify technical requirements which have to be met by the vendors. Especially vendors that cover the entire energy automation chain with their product portfolio have to face several new demanding challenges. The authors describe suitable approaches and implementation issues that are derived from selected IEC 62351 requirements following the product lifecycle process. (orig.)

    Considerable experience and research has been accumulated in the last 20 years on the ways in which information/education/communication (IEC) programs can be effectively designed, implemented, and evaluated. Possibly more effort has focused on population and family planning IEC than on any other sectoral program of development communication. Several principles have emerged which, taken together, define the state of the art in the field. These principles provide a framework of experience which can guide the development of comprehensive IEC programs. They include: policy and resource assessment; audience analysis; strategy design; message research and pretesting; participation and feedback; management; evaluation; and collaboration. The nature of the national policy base for population and family planning programs will determine the goals and approaches of the IEC program. Strong policies of limitation on popultion growth lead to equally strong and pervasive IEC efforts designed to directly affect contraceptive behavior. Assessment of existing policy is an essential aspect of the design of an effective IEC program. Policies establish the rationale and boundaries for action. Population and family planning programs are concerned with some of the most intimate human behavior. Consequently, structured and sensitive audience analysis has become an integral part of the design of IEC programs. The design of communication strategy requires clearly stated objectives. Principles of human learning are used to structure information appropriately. Message research and pretesting have become integral components of the strategy design process. Small scale research on specific objectives is necessary to establish the basis for message design. Audience participation and feedback in remaining phases of program development and implementation are important. The management of an IEC program requires a specific combination of planning, flexibility, and creativity. Evaluation of program

  15. Radiation cross-linked plastics: a versatile material solution for packaging, automotive, Electrotechnic and Electronics

    2004-01-01

    Used since the beginning of the 1970s for the production of halogen-free and heat-resistant cables and wires, for conditioning polyethylene hot-water pipes or for the manufacture of heat shrinkable tubes and of tyres, radiation cross-linking is developing fastly today on the scale of plastic-moulded parts, and not only by the mean of EB, but also under gamma rays. Indeed, it improves considerably the performances of a great number of plastics among thermoplastics, elastomers and thermoplastic elastomers (TPE). Radiation cross-linking reinforces the dimensional stability of polymers in chemically aggressive and high-temperature conditions. Radiation cross-linked-based engineering plastics offers OEM and end users in many branches of industry both technical and economical advantages in comparison with high-performances plastics. They constitute a technical and economical compromise between engineering plastics that failed and high-performances plastic, often over-tailored and expensive. This modern industrial technology gives way to new applications and perspectives in various sectors (packaging, automotive, electrotechnic and electronics, including connectors, surface-mounted devices, integrated circuits, 3D-MID, etc.) that are described in the paper

    1999-06-01

    Inertial Electrostatic Confinement fusion grade plasma containment has been sporadically researched since the early 1960's. In the 1990's the work of G. H. Miley and his team at the University of Illinios, Fusion Studies Laboratory, Champaign-Urbana has stimulated a collaboration with industry. The development and test program for the first industrial IEC neutron generator has progressed to the point where an endurance test is under way to demonstrate at least 10,000 hours of operational life of the sealed chamber device without servicing. The market entry goals of steady 107 D-D n/s CW output with an air-cooled system have been achieved. DASA has invested in the development of the industrial product and the continuing basic research at the UI-FSL. The complete DASA FusionStar IEC-PS1 point source neutron generator set is described with emphasis on the interfaces to user NAA systems. The next product developments are pulsed neutron operations and higher fusion reaction rates of up to 1010 by means of affordable add-ons to the basic IEC-PS system. The production engineering experience gained will next be applied to a more challenging line source variant of the IEC. Beyond neutron and proton sources, several other IEC applications are being developed.

    Inertial Electrostatic Confinement (IEC) is one of the earliest plasma confinement concepts, having first been suggested by P.T. Farnsworth in the 1950s. The concept involves a simple apparatus of concentric spherical electrostatic grids or a combination of grids and magnetic fields. An electrostatic structure is formed from the confluence of electron or ion beams. Gridded IEC systems have demonstrated neutron yields as high as 2*10 [10]. neutrons/sec in steady state. These systems have considerable potential as small, inexpensive, portable neutron sources for assaying applications. Neutron tomography is also a potential application. This paper discusses the IEC concept and how it can be adapted to a steady-state assaying source and an intense pulsed neutron source. Theoretical modeling and experimental results are presented

    Rapid access to any point in the solar system requires advanced propulsion concepts that will provide extremely high specific impulse, low specific power, and a high thrust-to-power ratio. Inertial Electrostatic Confinement (IEC) fusion is one of many exciting concepts emerging through propulsion and power research in laboratories across the nation which will determine the future direction of space exploration. This is part of a series of papers that discuss different applications of the Inertial Electrostatic Confinement (IEC) fusion concept for both in-space and terrestrial use. IEC will enable tremendous advances in faster travel times within the solar system. The technology is currently under investigation for proof of concept and transitioning into the first prototype units for commercial applications. In addition to use in propulsion for space applications, terrestrial applications include desalinization plants, high energy neutron sources for radioisotope generation, high flux sources for medical applications, proton sources for specialized medical applications, and tritium production

    Use of a combined X-ray and neutron source for security inspections based on Inertial Electrostatic Confinement (IEC) fusion is discussed. Current inspection systems typically use X-ray techniques, but thermal neutron analysis (TNA) and fast neutron analysis (FNA), allow expanded detection of certain types of explosives. The integrated unit proposed here uses three separate IEC sources producing 14 and 2.45 MeV neutrons plus soft X-rays. This combination allows multiple detection methods with the composite signal analysis being done by a fuzzy logic system, significantly reducing false signals. (author)

    With an objective to enhance international emergency preparedness and response (EPR), the IAEA Board of Governors in 2004 approved the five-year International Action Plan for Strengthening the International Preparedness and Response System for Nuclear and Radiological Emergencies. In 2010 the action plan activities ended with a report that identified activities that need to be addressed by Member States and the IAEA Secretariat, recommended key strategic elements for successful implementation of sustainable EPR systems, and provided a number of detailed recommendations on international communications, international assistance and sustainable infrastructure. One of the key strategic elements recommended was to establish a senior EPR advisory group that would provide advice on EPR matters to the IAEA's Deputy Director General, Head of the Department of Nuclear Safety and Security. The Emergency Preparedness and Response Expert Group (EPREG) was established at the end of 2012 as a standing body of senior experts with high professional competence and demonstrated leadership in the field of preparedness for and response to radiation emergencies to provide advice to the IAEA Secretariat on actions needed to ensure continuous and coordinated EPR enhancement and implementation strategies. The group consists of 16 experts in EPR covering all regions. The first meeting of EPREG was convened on 11 and 12 February 2013. The purpose of the meeting was to constitute the EPREG, to discuss current international activities in the area of emergency preparedness and response and to discuss priorities for their further implementation

    ConvEx exercises (Convention Exercises) are prepared for Member States and relevant international organizations by the IAEA under the framework of the Convention on Early Notification of a Nuclear Accident and the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency. These exercises are carried out at three levels of complexity with the third level (ConvEx-3) being a full scale exercise prepared every three to five years within the Inter-Agency Committee on Radiological and Nuclear Emergencies (IACRNE), which comprises 17 international intergovernmental organizations. ConvEx-3 (2013), code-named 'Bab Al Maghrib', was hosted by Morocco and designed to allow Member States and international organizations to evaluate their response in a severe radiological emergency triggered by a nuclear security event and to identify emergency preparedness and response (EPR) areas requiring improvements. The exercise was conducted on 20 and 21 November 2013 and lasted approximately 25 hours. Fifty-nine Member States (including Morocco) and ten international organizations (including the IAEA) participated in the exercise. Twenty-four of the participating Member States and six of the international organizations participated in the exercise at the highest level possible (Level B) to actively test their EPR arrangements and capabilities for responding to such an event, and to test the sharing and exchange of information internationally. During the exercise, several Member States actively offered their national assistance capabilities to the exercise Accident State (Morocco). It was the first time in the history of ConvEx-3 exercises that country specific injects were prepared in a way that required specific Member State responses.

    2002-01-01

    A preliminary system design is presented for a high performance 100-MWe manned space vehicle in the 500 metric ton class, based on Inertial Electrostatic Fusion (IEC), allowing trip times to the outer planets of several months. An IEC is chosen because it's simplified structure results in a very high power-to-weight ratio. D- 3 He fuel is used to give 14.7-MeV protons as a primary fusion reaction product. Direct conversion of proton energy to electricity is employed, providing a high efficiency. An IEC reactor with a proton energy gain (power in 14.7-MeV protons/input electric power) of 4 or better is assumed. Extrapolation of present laboratory scale IEC experiments to such conditions is possible theoretically, but faces several open issues that require further study such as stability under high-density conditions. The final thruster is based on an NSTAR-extrapolated krypton ion design with a specific impulse of 16,000 seconds and a total thrust of 1020 N. Round trip thrust time for mission set to Jupiter ΔV of 100 km/s is then ∼950 days. (authors)

  7. Inertial electrostatic confinement (IEC) fusion fundamentals and applications

    CERN Document Server

    Miley, George H

    2014-01-01

    This book provides readers with an introductory understanding of Inertial Electrostatic Confinement (IEC), a type of fusion meant to retain plasma using an electrostatic field. IEC provides a unique approach for plasma confinement, as it offers a number of spin-off applications, such as a small neutron source for Neutron Activity Analysis (NAA), that all work towards creating fusion power. The IEC has been identified in recent times as an ideal fusion power unit because of its ability to burn aneutronic fuels like p-B11 as a result of its non-Maxwellian plasma dominated by beam-like ions. This type of fusion also takes place in a simple mechanical structure small in size, which also contributes to its viability as a source of power. This book posits that the ability to study the physics of IEC in very small volume plasmas makes it possible to rapidly investigate a design to create a power-producing device on a much larger scale. Along with this hypothesis the book also includes a conceptual experiment propose...

  8. Can we use IEC 61850 for safety related functions?

    Directory of Open Access Journals (Sweden)

    Luca Rocca

    2016-08-01

    Full Text Available Safety is an essential issue for processes that present high risk for human beings and environment. An acceptable level of risk is obtained both with actions on the process itself (risk reduction and with the use of special safety systems that switch the process into safe mode when a fault or an abnormal operation mode happens. These safety systems are today based on digital devices that communicate through digital networks. The IEC 61508 series specifies the safety requirements of all the devices that are involved in a safety function, including the communication network. Also electrical generation and distribution systems are processes that may have a significant level of risk, so the criteria stated by the IEC 61508 applies. Starting from this consideration, the paper analyzes the safety requirement for the communication network and compare them with the services of the communication protocol IEC 61850 that represents the most used protocol for automation of electrical plants. The goal of this job is to demonstrate that, from the technical point of view, IEC 61850 can be used for implementing safety-related functions, even if a formal safety certification is still missing.

    On 28 March, the Incident and Emergency Centre (IEC) conducted its first Full Response Exercise of 2012. Over 30 staff members from the Department of Nuclear Safety and Security and the Division of Public Information participated. The IEC was activated into full response mode at approximately 9 a.m. This full response lasted most of the day and led up to a 'lessons learned' discussion at the end of the day. Florian Baciu, the IEC Response System Coordinator, noted: ''Although many of the participants were involved in the IAEA response to the accident at TEPCO's Fukushima Daiichi nuclear power plant, this exercise gave them the opportunity to practice procedures which they had not used since then. In addition, we had several staff members relatively new to the IAEA's Incident and Emergency System among the participants.'' Hilaire Mansoux, one of the Emergency Response Managers for the exercise, stated: ''The scenario was quite complex, requiring a good flow of information.'' The IEC staff had developed a scenario in which a meltdown and resulting release of radioactive materials to the environment from a nuclear power plant in a Member State was caused by a criminal act. All outside organizations were represented by the IEC staff in a simulation cell, which periodically contributed information using telephone calls, faxes, emails and messages through the IAEA's Unified System for Information Exchange in Incidents and Emergencies (USIE). The tasks of the IAEA in the area of emergency response were expanded through the mandate given by Member States following the events at Fukushima Daiichi last year. In the area of communication and information dissemination, the IAEA was also given, among other tasks, the mandate to assess emergency situations by providing 'analysis of available information and prognosis of possible scenarios'. Together with other matters, the assessment aspect was addressed in this full response exercise.

    This dossier gathers a series of short articles about energy security and efficiency in a context of policy transition. The first paper deals with the use of international standards to promote energy efficiency thanks to efficient public policies and private sector actions. This was the main topic of the mixed workshop organized by the International electrotechnics Commission (IEC) in spring 2009. The second paper presents the new strategic analysis of the European commission in the domain of energy which stresses on the '20-20-20' climate change proposals approved in December 2008. A new European action plan for energy security and solidarity defines 5 domains requiring an extra action to warrant a sustainable energy supply. The commission is also examining the challenges that Europe will have to face between 2020 and 2050. The third article treats of the security of natural gas supplies which represents a quarter of the European Union (EU) energy mix. The supply crises susceptible to occur may have serious economic and social consequences. Therefore, the EU must be prepared to warrant its security of supplies. Cogeneration allows the EU to stay close to its energy goals. Buildings play a key role in the realisation of the EU's energy saving objectives and fight against climate change. The new directive on buildings energy efficiency (2002/91/CE) will allow to exploit this potential of saving and to stimulate sustainable investment and employment as well. Finally, the publication of the second WBCSD (World business council for sustainable development) international report on buildings energy efficiency has led GDF Suez utility to reaffirm its commitment in favour of energy saving and efficiency.

    2006-01-01

    Nuclear power plants (NPPs) are increasingly faced with the challenge of qualifying procured equipment, sub-components, and systems that contain digital programmed electronics for use in safety-related applications. Referred to as a 'programmable electronic system' (PES), such equipment typically contains both complex logic that is vulnerable to systematic design faults, and low voltage electronics hardware that is subject to random faults. Procured PES products or components are often only commercial grade, yet can offer reliable cost effective alternatives to custom-designed or nuclear qualified equipment, provided they can be shown to meet the quality assurance, functional safety, environmental, and reliability requirements of a particular application. The process of confirming this is referred to as application-specific product qualification (ASPQ) and can be challenging and costly. This paper provides an overview of an approach that has been developed at Atomic Energy Canada Limited (AECL) and successfully applied to PES equipment intended for use in domestic Candu R 6 nuclear power plants and special purpose reactors at Chalk River Laboratories. The approach has evolved over the past decade and has recently been adapted to be consistent with, and take advantage of new standards that are applicable to nuclear safety-related I and C systems. Also discussed are how recognized third-party safety-certifications of PES equipment to International Electrotechnical Commission (IEC) standards, and the assessment methods employed, may be used to reduce ASPQ effort.

    The Thermoluminescence Personal Dosimetry Laboratory of the University of Costa Rica provides dose measurements for around 90% of occupational radiation workers in the country. The assessment of doses to workers routinely exposed to external sources of radiation constitutes an integral part of any radiation protection programme and helps national authorities to ensure acceptably safe and satisfactory radiological conditions in workplaces. Harshaw Readers Model 4000 and 4500, dosimeter holders Type 8814 with TLD-100 in 0110 cards and loose TLD-100 chips are used to monitor personal dose equivalent, Hp(10) and Hp(0.07). In order to provide a reliable measurement of the operational quantities, a study was undertaken to verify the fulfillment of international requirements in our system (Model 4500 with cards) against the Thermoluminescence dosimetry systems for personal and environmental monitoring CEI IEC 61066 (1991 -2012). The type tests performed were nine in total: batch homogeneity, reproducibility, linearity, detection threshold, effect of climate conditions on reader, effect of light exposure on dosimeters, isotropy, transient voltage and dropping on dosimeters. A Cesium-137 source was used to irradiate the dosimeters and all procedures follow the indications given on the standard. Results showed that all IEC criteria were met by our Laboratory. Acceptable uncertainties were also studied under the ICRP recommendations; the analysis of the Trumpet Curve was done with satisfactory results (for doses above 0.5 mSv; quotient of measure to real dose less than 3%). For purposes of accreditation (ISO/IEC 17025:2005) and performance testing this work is very relevant since the University of Costa Rica wants to establish a solid individual monitoring programme for external radiation exposure that will provide users, registrants, licensees and regulatory bodies with information that can be used for the optimization of protection and dose limitation of Costa Rican workers

    2002-01-01

    The collimator-converter system extracts fusion power from D- 3 He fueled IEC devices and provides electricity needed to operate ionic thrusters and other-power components. The whole system is linear and consists of a series of collimator units at the center, magnetic expander units at both sides of the fusion units, followed by direct energy converters at both ends. This system is enclosed in a vacuum chamber with a magnetic channel provided by magnetic solenoids out of respective chambers. The fusion unit consists of an IEC fusion core, a pair of coils anti-parallel to the solenoid coils, and a stabilization coil that stabilizes the position of coil pair coils. The IEC fusion core is installed at the center of the pair coils. After the magnetic expander, velocities of fusion particles from D- 3 He fueled IEC units are directed to the magnetic channel, which guides energetic fusion particles as well as leaking unburned fuel components to a high-efficiency traveling wave direct energy converter (TWDEC). Leaking unburned fuel components are separated with a magnetic separator at the entrance of a direct energy converter and pumped out for further refueling. A TWDEC is made of an array of metallic meshed grids, each of which is connected to every terminal with an external transmission circuit. The transmission line couples to the direct energy converter. Substations for electricity, a cryogenic plant, and various power control systems are outside of the vacuum chamber. The length of the cylindrical system is essentially determined by the proton energy of 14.8 MeV and the radius should be large so as to reduce power flow density. The present system provides 250 MW f fusion power and converting it to 150 MW c electricity. Its size is 150 m(length)x6.6 m(diameter) in size and 185 tons in weight

    'Medical Devices' include everything from highly sophisticated, computerized, medical equipment, right down to simple wooden tongue depressors. Regulations embody the public expectations for how buildings and facilities are expected to perform and as such represent public policy. Regulators, who develop and enforce regulations, are empowered to act in the public's interest to set this policy and are ultimately responsible to the public in this regard. Standardization contributes to the basic infrastructure that underpins society including health and environment, while promoting sustainability and good regulatory practice. The international organizations that produce International Standards are the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO), and the International Telecommunication Union (ITU). With the increasing globalization of markets, International Standards (as opposed to regional or national standards) have become critical to the trading process, ensuring a level playing field for exports, and ensuring that imports meet the internationally recognized levels of performance and safety. The development of standards is done in response to sectors and stakeholders that express a clearly established need for them. An industry sector or other stakeholder group typically communicates its requirement for standards to one of the national members. To be accepted for development, a proposed work item must receive a majority support of the participating members, who verify the global relevance of the proposed item. The regulatory authority (RA) should provide a method for the recognition of international voluntary standards and for public notification of such recognition. The process of recognition may vary from country to country. Recognition may occur by periodic publication of lists of standards that a regulatory authority has found will meet the Essential Principles. In conclusion, International standards

    2000-08-01

    The paper describes a concept of extracting fusion power from D- 3 He fueled IEC (Inertia Electrostatic Configuration) devices. The fusion system consists of a series of fusion modules and direct energy converters at an end or at both ends. This system of multiple units is linear and is connected by a magnetic field. A pair of coils anti-parallel to the magnetic field yields a field-null domain at the center of each unit as required for IEC operation. A stabilizing coil installed between the coil pairs eliminates the strong attractive force between the anti-parallel coils. Accessible regions for charged particle trajectories are essentially isolated from the coil structure. Thus, charged particles are directed along magnetic field lines to the direct energy converter without appreciable losses. A direct energy converter unit designed to be compatible to this unique system is also described. It basically consists of a separator and a traveling wave converter. A separator separates low energy ions and electron from the 14.7 MeV fusion protons and then converts their energy into electricity. In the traveling wave direct energy converter, fusion protons are modulated to form bunches. It couples with a transmission line to couple AC power out. The overall conversion efficiency of this system, combined with E- 3 He IEC cores, is estimated as high as 60%. (author)

    Electric utilities are currently facing the challenge of refurbishing aging transmission networks and power system infrastructure at a time of severe economic, environmental and competitive constraints. This paper addressed the issue of an appropriate approach to retrofit the hardware and software of substation secondary systems, and how IEC standards could be used to set up a long term strategy. The first part of the paper considered an asset management strategy for refurbishing substation secondary systems, while the second part of the paper addressed the strategies for refurbishing existing power plants. The final section of the paper analyzed refurbishment strategies designed to protect power distribution systems. The impact of IEC 61850 and how legacy devices can be integrated in substation automation systems were discussed. It was concluded that new SCADA systems are needed to handle new technology. Additional features like remote control, remote settings, remote disturbance records analysis and remote maintenance are also needed to properly operate the power system. The value of preventive maintenance using remote monitoring systems to determine the status of all the digital electronic devices installed in substation was also discussed. IEC 61850 offers several opportunities to improve grid operation and control. It supports interoperability between protective relays and control devices from different manufacturers in the substation, which is required in order to achieve substation level interlocking, protection and control functions and improve the efficiency of microprocessor based relays applications. This technology has now passed the initial stage of implementation and several projects are underway worldwide. 13 figs.

    Full Text Available Automatically identifying the new equipment after its integration and adjusting operation strategy to realize “plug and play” functionality are becoming essential for micro-grid operations. In order to improve and perfect the micro-grid “plug and play” function with the increased amount of equipment with different information protocols and more diverse system applications, this paper presents a solution for adaptive micro-grid operation based on IEC 61850, and proposes the design and specific implementation methods of micro-grid “plug and play” function and system operation mode conversion in detail, by using the established IEC 61850 information model of a micro-grid. Actual operation tests based on the developed IED and micro-grid test platform are performed to verify the feasibility and validity of the proposed solution. The tests results show that the solution can automatically identify the IEC 61850 information model of equipment after its integration, intelligently adjust the operation strategies to adapt to new system states and achieves a reliable system operation mode conversion.

    A resurgence in nuclear power use is now underway worldwide. However, due many university research reactors shutdown, they must rely on using subcritical assemblies which employs a cylindrical Inertial Electrostatic Confinement (IEC) device to provide a fusion neutron source. The source is inserted in a fuel element position, with its power input controlled externally at a control panel. This feature opens the way to use of the critical assembly for a number of transient experiments such as sub-critical pulsing and neutron wave propagation. That in turn adds important new insights and excitement for the student teaching laboratory. (author)

  7. US-Japan IEC Workshop on Small Plasma and Accelerator Neutron Sources. Final report

    International Nuclear Information System (INIS)

    Miley, George H.

    2008-01-01

    The history of IEC development will be briefly described, and some speculation about future directions will be offered. The origin of IEC is due to the brilliance of Phil Farnsworth, inventor of electronic TV in the US. Early experiments were pioneered in the late 1960s by Robert Hirsch who later became head of the DOE fusion program. At that time studies of IEC physics quickly followed at the University of Illinois and at Penn State University. However, despite many successes in this early work, IEC research died as DOE funding stopped in the mid 1980s. In the early 90's, R. W. Bussard of EMC revived work with a new major project based on a magnetic assisted IEC. While doing supportive studies for that project, G. Miley proposed a grided 'STAR mode' IEC as a neutron source for NAA. This concept was later used commercially by Daimler-Benz in Germany to analysis impurities in incoming ores. This represented a first practical application of the IEC. During this period other research groups at LANL, U of Wisconsin and Kyoto University entered IEC research with innovative new concepts and approaches to IEC physics and applications. Much of this work is documented in the present and in past US-Japan Workshops. At present we stand on the threshold of a new area of IEC applications as neutron source, for isotope production, and as a plasma source. These applications provide a way to continue IEC understanding and technology development with the ultimate goal being a fusion power plant. Indeed, a distinguishing feature of the IEC vs. other fusion confinement approaches is the unique opportunity for 'spin off' applications along the way to a power producing plant.

    Needs for harmonization of international equipment qualification(EQ) standards have been raised several years due to purchasing problem of nuclear equipment supplied from abroad country. To meet the regulatory requirement of domestic nuclear power plant, manufacturers have to qualify their equipment in accordance with each standard such as IEEE, IEC and RCC-E. Double qualification increase the equipment cost, which result in high construction cost. Even the unification of each standard have been discussed several years, we have got the long way to go yet. Comparison and harmonization of each international standard will give help to purchase the equipment qualified by not endorsed standard. Environmental qualification, seismic qualification and EMI/EMC qualification are major targets for harmonization. Since concern about cable qualification of 60 years life has been raised recently, harmonization of cable qualification standard also needs to be discussed. KEPRI launched a project for harmonization of EQ relative standards such as IEEE, IEC and RCC-E. A study for harmonization of IEEE323 and IEC60780 is known in progress by IEEE committee. In this paper, harmonization of international standards for cable qualification will be discussed. IEEE383 standard is qualification standard for electric cable broadly used in Asian pacific area while IEC60505 is mostly used in European area. Since these two standards have different requirements for environmental qualification of cable, problem can be happened in the plant site when they purchase cable qualified by not endorsed standard. IEEE383-2003 and IEC60505-2004 is the latest version of each standard. Comparison results and recommendations for harmonization of these two standards are introduced herein

    This paper presents the implementation of the generic wind turbine generator (WTG) electrical simulation models proposed in the IEC 61400-27 standard which is currently in preparation. A general overview of the different WTG types is given while the main focus is on Type 4B WTG standard model, namely a model for a variable speed wind turbine with full scale power converter WTG including a 2-mass mechanical model. The generic models for fixed and variable speed WTGs models are suitable for fundamental frequency positive sequence response simulations during short events in the power system such as voltage dips. The general configuration of the models is presented and discussed; model implementation in the simulation software platform DIgSILENT PowerFactory is presented in order to illustrate the range of applicability of the generic models under discussion. A typical voltage dip is simulated and results from the basic electrical variables of the WTG are presented and discussed. (orig.)

    The Brazilian Sanitary Agency from Ministry of Health requires that all PET/CT equipment must undergo minimal quality control tests using manufacturer simulators. The PET-NEMA/IEC body phantom is recommended by the IEC and NEMA to perform acceptance testing and quality control in PET/CT equipment according to specific protocols. It is essential that all simulator components (spheres and body) are properly characterized in relation to their size and internal structure volumes, since they are used to calculate the overall activity concentration and the total weight. The objective of this work was characterize a PET-NEMA/IEC body phantom for the true reconstruction in computational modeling and correct analysis of experimental results. The simulator is basically composed of three structures: the body (simulating a portion of the chest), an inner cylinder (simulating the lung tissue) and a top cover in which are coupled spheres of different sizes simulating 'hot' (tumors) and cold lesions. The spheres were evaluated in terms of volume. The same evaluations were performed with the body of the simulator and the inner cylinder, beyond of analysis of their weights (filled with water) and wall thickness. The data showed that the total weight of the simulator with all its internal structures is 12.5 kg and the volume of the 'hot' and 'cold' spheres are approximately equal to those presented by the manufacturer. The inner cylinder volume showed a significant difference between the measured and the presented in the manual. The results were used for reconstruction of the simulator in computational modeling using the code GATE. (author)

    The requirements for future manufacturing plants are, beyond others, seamless reconfiguration, autonomy as far as possible as well as easy employment and maintenance for the end user. Within the EnAS project (Energy-Autarkic Actuators and Sensors), the group of the Automation Technology Lab in Halle has challenged the fulfillment of those requirements. Therefore, IEC 61499 compliant distributed controllers have been developed for the demonstrator-plant under particular consideration of reconfigurability. These controllers have been integrated into the process sequences of the demonstrator and afterwards several reconfiguration scenarios have been designed. The building of a Human-Machine-Interface for visualization and reconfiguration of the plant was an essential issue as well. The result is a highly flexible, easily reconfigurable system, which can be regarded as a prototype for automated manufacturing plants of a new generation. (orig.)

  20. Can non-regulators audit Independent Ethic Committees (IEC), and if so, how?

    Science.gov (United States)

    Dent, N J; Sweatman, W J

    A number of guidelines and directives have reinforced the need for a more formalised approach to Independent Ethic Committees (IECs) and support the need to audit IECs. The key elements of an audit of an IEC are reviewed within the context of the European Guidelines for Auditing Independent Ethics Committees published by the European Forum for Good Clinical Practice (EFGCP). Auditing requirements in these recent guidelines and the EU Clinical Trial Directive are discussed as well as the methodology and type of documentation and SOPs that should be present at an audit. It is argued that both inspectorates and independent auditors need to conduct such audits to improve the overall global standard.

    Previous studies have shown that Single-State-to-Orbit (SSTO) vehicle propellant can be reduced by Magnets-Hydro-Dynamic (MHD) processes that minimize airbreathing propulsion losses and propellant consumption during atmospheric flight, and additional reduction in SSTO propellant is enabled by Inertial Electrostatic Confinement (IEC) fusion, whose more energetic reactions reduce rocket propellant needs. MHD airbreathing propulsion during an SSTO vehicle's initial atmospheric flight phase and IEC fusion propulsion during its final exo-atmospheric flight phase is therefore being explored. Accomplished work is not yet sufficient for claiming such a vehicle's feasibility. But takeoff and propellant mass for an MHD airbreathing and IEC fusion vehicle could be as much as 25 and 40 percent less than one with ordinary airbreathing and IEC fusion; and as much as 50 and 70 percent less than SSTO takeoff and propellant mass with MHD airbreathing and chemical rocket propulsion

    Full Text Available The open-platform communication (OPC unified architecture (UA (IEC62541 is introduced as a key technology for realizing a variety of smart grid (SG use cases enabling relevant automation and control tasks. The OPC UA can expand interoperability between power systems. The top-level SG management platform needs independent middleware to transparently manage the power information technology (IT systems, including the IEC 61850. To expand interoperability between the power system for a large number of stakeholders and various standards, this paper focuses on the IEC 61850 for the digital substation. In this paper, we propose the interconnection method to integrate communication with OPC UA and convert OPC UA AddressSpace using system configuration description language (SCL of IEC 61850. We implemented the mapping process for the verification of the interconnection method. The interconnection method in this paper can expand interoperability between power systems for OPC UA integration for various data structures in the smart grid.

    A description is given of the properties of superconducting materials and of other materials which will be used in low temperature electrical engineering. The electrical and magnetic properties of type 1 or soft and type 2 or hard superconducting materials are analyzed. Electroinsulating and magnetic materials at low temperatures are also surveyed. Emphasis is placed on gaseous and fluid dielectric substances which retain their condition of physical aggregation at low temperatures and provide a cryogenic medium. These include helium, hydrogen, and nitrogen. As for solid dielectrics, satisfactory electroinsulating materials in terms of mechanical and electrical properties include the category of thermoplastic organic materials such as mylar, teflon, kapton, and nylon. It is also emphasized that cryoelectrical engineering requires magnetic materials with high magnetic induction at low temperatures, coercive field and low magnetic loss.

    Different Insulin-like growth factor-I (IGF-I) mRNA transcripts are produced by alternative splicing and particularly the IGF-IEc isoform has been implicated in the development and/or progression of various types of cancer. In the present study, we examined the potential role of IGF-IEc expression as a new immunohistochemical marker of aggressiveness in neuroendocrine neoplasms (NENs). We utilized immunohistochemical analysis in tissue specimens of 47 patients with NENs, to evaluate the expression of IGF-IEc (%) and Ki-67 proliferation index (%). Specimens from patients with tumors of different tissue origin, of either primary or metastatic lesions and of different grade were examined. Cytoplasmic IGF-IEc staining was found in 23 specimens of NENs or NECs: 10 pancreatic, 4 small bowel, 3 gastric, 1 lung, 1 uterine and 4 poorly differentiated of unknown primary origin. Ki-67 and IGF-IEc expression was positively correlated in all the samples studied (r=0.31, p=0.03). IGF-1Ec expression was more prevalent in specimens originating from metastatic foci with high Ki-67 compared to primary sites with low Ki-67 expression (p=0.036). These findings suggest a possible role of IGF-IEc in NEN tumorigenesis and progression to metastases that could be used as an additional new marker of a more aggressive behavior and a potential drugable target.

It is intended for those responsible for making and for acting on decisions in the event of an emergency involving actual or projected severe damage to the fuel in the reactor core or in the spent fuel pool of a light water reactor, to provide an understanding of the actions necessary to protect the public. It provides a basis for developing the tools and criteria at the preparedness stage that would be needed to take appropriate protective actions and other actions in response to an emergency. It provides guidance on: - Taking actions to protect the public based on conditions at the nuclear power plant using an emergency classification system; - Assessing environmental monitoring measurements taken after a release of radioactive material to determine if protective actions are needed; and - How to place the radiological health hazard in perspective for the public and answer key questions, such as ''Am I safe?'' and ''What do I need to do to protect myself and family?'' The publication is currently only available in English, but will soon be available in Spanish and Russian. The associated training materials will be available from the IAEA's and the Incident and Emergency Centre's websites later this year, and are also planned to be translated into other official UN languages. In addition, the IEC offers workshops on this publication at the national, regional and inter regional levels when requested by a Member State.

    Powder X-ray diffraction (PXRD) is used widely in forensic science laboratories with the main focus of qualitative phase identification. Little is found in literature referring to the topic of validation of PXRD in the field of forensic sciences. According to EN ISO/IEC 17025, the method has to be tested for several parameters. Trueness, specificity, and selectivity of PXRD were tested using certified reference materials or a combination thereof. All three tested parameters showed the secure performance of the method. Sample preparation errors were simulated to evaluate the robustness of the method. These errors were either easily detected by the operator or nonsignificant for phase identification. In case of the detection limit, a statistical evaluation of the signal-to-noise ratio showed that a peak criterion of three sigma is inadequate and recommendations for a more realistic peak criterion are given. Finally, the results of an international proficiency test showed the secure performance of PXRD. © 2012 American Academy of Forensic Sciences.

    Inertial Electrostatic Confinement (IEC) is a unique approach to fusion and plasma energy systems that was conceptualized in the 1960s (Hirsch 1967) and has been the focus of recent development in the 1990s (Miley et al. 1995a). In the interests of space power and propulsion systems, conceptual rocket design studies (Bussard and Jameson 1994, Miley et al. 1995b) using the IEC have predicted excellent performance for a variety of space missions, since the power unit avoids the use of magnets and heavy drives resulting in a very high, specific impulse compared to other fusion systems. In their recent survey of prior conceptual design studies of fusion rockets, Williams and Borowski (1997) found that the Bussard IEC conceptual study (the open-quotes QEDclose quotes engine) offered a thrust-to-weight ratio of 10 milli-g close-quote s, a factor of five higher than conventional magnetic confinement concepts and even slightly above anti-proton micro fission/fusion designs. Thus there is considerable motivation to study IEC concepts for eventual space applications. However, the physics feasibility of the IEC still requires experimental demonstration, and an expanded data base is needed to insure that a power unit can in fact be built. copyright 1998 American Institute of Physics

    Full Text Available ISO/IEC 17025 is an international standard that specifies the general requirements for evaluating the competence of laboratories involved in testing and calibration. This standard brings several benefits to university laboratories, which, thus, seek to obtain the accreditation. However, although cost is one of the main obstacles in this process; this topic has not been sufficiently studied. Since the Universidade Federal de Santa Maria (UFSM supports its laboratories for the implementation of this standard, it was chosen for this article to identify and quantify the accreditation costs of its laboratories that have obtained it or are working toward the goal. An exploratory literature review was carried out, and the data gathered were analyzed qualitatively and quantitatively. This study observed that the costs related to hours worked are linked to staff qualification and that high expenses in equipment and infrastructure occur in laboratories that receive financial resources from external providers.

    IEEE323 standard has been widely used for the qualification of electric equipment in Asian pacific area while IEC6070 has been mostly used in European area. Since each plant use different standard for environmental qualification, manufacturer has to perform the qualification test twice in accordance with each standard. Problem also can be happened in the plant site when they are going to purchase equipment qualified by different qualification standard which are not used in his plant. The need of harmonization of each standard has been raised several years and it is known that some studies are in progress by IEEE committee. KEPRI has a plan of comparing EQ relative standards of IEEE, IEC and RCC in 2009. In this paper, brief comparing result between IEEE323 and IEC60780 and the proper harmonization method is introduced

    This book proposes a presentation of AC electric motors essentially based on physics and technology. Its originality consists in avoiding to use mathematical formulations (like Park's transformation). The modeling retained, which only uses magnetic momentum, magnetic fields and reluctance concepts, leads simply and naturally to the vectorial control principle. The book develops some lecture elements which includes some topics rarely considered like the dimensioning of an asynchronous motor or of a single-phase brush-less motor. Experimental results illustrate the physical phenomena described and many original problems are resolved and commented at the end of each chapter. Content: signals and systems in electrotechnics, torque and rotating magnetic fields generation, asynchronous machine in permanent regime, speed variation of the asynchronous motor, special asynchronous motors, synchronous machine in permanent regime, brush-less motor, note about step motors, note about inverters, index.

    Calibration of quality control (QC) test tools used in diagnostic radiology is legally required under the Ministry of Health (MOH) requirement. The Medical Physics Calibration Laboratory of the Malaysian Nuclear Agency is the national focal point for the calibration of quality control test tools used in diagnostic radiology. The Medical Physics Calibration Laboratory has measurement traceability to primary standard dosimetry laboratory (Physikalisch-Technische Bundesanstalt (PTB)), thus providing an interface between the primary standard dosimetry laboratory and Malaysian hospitals, clinics and license class H holder. The Medical Physics Calibration Laboratory facility is comprised of a constant potential x-ray system with a capability of 160 kV tube and a series of reference and working standard ion chambers. The stability of reference and working standard ion chambers was measured using strontium-90. Dosimetric instruments used in diagnostic radiology is calibrated in terms of air kerma to comply with an International Code of Practices of dosimetry for example IAEA's Technical Report Series number 457. The new series of standard radiation qualities was established based on ISO/IEC 61267. The measurement of beam homogeneity was measured using film and ion chamber to define the field size at certain distance and kV output was measured using the spectrometer and non-invasive kVp meter. The uncertainties measurement was determined with expended uncertainties to a level of confidence of approximately 95% (coverage factor k=2). This paper describes the available facility and the effort of the Medical Physics Calibration Laboratory to upgrade the laboratory towards ISO/IEC 17025. (author)

    Correa, Eduardo de Lima

    2010-01-01

    In this work it was developed and applied a quality control program of the X radiation system (160 kV, constant potential, target of tungsten) of the Calibration Laboratory of IPEN(LCI) in the energy range relative to mammography beams (from 25 kV to 35 kV). The X radiation standards beams, level mammography, using molybdenum and aluminum as additional filtration, were established after the application of this quality control program following national and international recommendations. The reference ionization chamber has traceability to PTB and was regularly submitted to quality control tests for evaluation and analysis of its performance. The radiation qualities emerging from the X-radiation assembly (RQR-M), based on a phantom made up of an aluminum added filter (RQA-M), narrow beam condition (RQN-M) and broad beam condition (RQB-M), following the recommendations of the international standard IEC 61267 (2005) and the IAEA code of practice, TRS 457 (2007) were established. For the implantation of RQN-M and RQB-M radiation qualities, two mammography phantoms were developed. The half-value layers found are those presented by the German primary laboratory PTB, and varied from 0.35 to 1.21 mm Al. The air kerma rates were obtained for all the 15 implanted qualities.

    An inertial electrostatic confinement (IEC) device using spherical, gridded electrodes at high voltage accelerates deuterium ions, allowing for neutrons to be produced within the device from DD fusion reactions. The effects of the device cathode voltage (30-170 kV), current (30-100 mA), and pressure (0.15-1.25 mTorr) on the neutron production rate have been measured. New high voltage capabilities have resulted in the achievement of a steady state neutron production rate of 3.3x108 n/s at 175 kV, 100 mA, and 1.0 mTorr of deuterium. Applications of IEC devices include the production of DD neutrons to detect chemical explosives and special nuclear materials using active interrogation methods.

    The tendency of using a protocol allows electrical substations to become 'intelligent', that is, capable of communicating in a much more efficient manner. This greatly reduces the number of connections, and as a consequence optimizes the speed between messages. The Norm IEC 61850-9-2 came to minimize the use of cables for the interconnections of various equipment involved in safety procedures of a substation. The present paper, has the objective of identifying a way of integrating the Norm IEC-61850 with the transmission of data via 'Generic Object Oriented Substation Event' (GOOSE) and of substituting the direct connection of binary I/O's of the Intelligent Electronic Devices also known as IED's.

  2. Architectural constraints in IEC 61508: Do they have the intended effect?

    International Nuclear Information System (INIS)

    Lundteigen, Mary Ann; Rausand, Marvin

    2009-01-01

    The standards IEC 61508 and IEC 61511 employ architectural constraints to avoid that quantitative assessments alone are used to determine the hardware layout of safety instrumented systems (SIS). This article discusses the role of the architectural constraints, and particularly the safe failure fraction (SFF) as a design parameter to determine the hardware fault tolerance (HFT) and the redundancy level for SIS. The discussion is based on examples from the offshore oil and gas industry, but should be relevant for all applications of SIS. The article concludes that architectural constraints may be required to compensate for systematic failures, but the architectural constraints should not be determined based on the SFF. The SFF is considered to be an unnecessary concept

    Full Text Available This article discusses the implementation of a variety of logical nodes (LNs of power generation systems based on distributed energy resources (DER in a single board computer (SBC. The SBC allows for the acquisition and encapsulation of analog signals from a photovoltaic (PV array with batteries, based on the IEC 61850-7-420 standard. To achieve this, an SBC integrated with an analog-digital conversion card (ADC enables to read the system’s analog values. The SBC communicates with the ADC card to encapsulate the collected data in the IEC 61850 data object by using the corresponding logical node (LN. An open license library was used to create the IEC 61850 server inside the SBC and the driver of the ADC card manufacturer to communicate both cards. This work aims to develop LNs for DERs in such way that manufacturers of power generation technologies based on renewable sources (such as the sun and/or the wind implement Intelligent Electronic Devices (IED and controllers in accordance with the scope of the standard for these logical nodes (LNs. Finally, the communication testing of the implementation and the results obtained are presented.

  9. Maturity index on reliability: covering non-technical aspects of IEC61508 reliability certification

    International Nuclear Information System (INIS)

    Brombacher, A.C.

    1999-01-01

    One of the more recent developments in the field of reliability and safety is the realisation that these aspects are not only a function of the product itself, but also of the organisation realising this product. A second development is a trend from an often predominantly qualitative analysis towards a quantitative analysis. In contrast to the (older) DIN 0801, the (more recent) IEC61508 requires, on product level, also a quantitative analysis and, on organisational level, an assessment of the lifecycle of a product by analysing the (maturity of the) relevant business processes (DIN V VDE 0801. Grundsaetze fuer Rechner in Systemen mit Sicherheitsaufgaben, 1990; DIN V 0801. Grundlegende Sicherheitsbetrachtungen fuer MSR-Schutzeinrichtungen, 1994; DIN V VDE 0801 A1. Grundsaetze fuer Rechner in Systemen mit Sicherheitsaufgaben, Aenderung A1, 1994; IEC 61508 Functional Safety of electrical/electronic/programmable electronic safety-related systems, draft 4.0, 1997). The IEC standard 61508 covers: (i) technical aspects, both on a quantitative and a qualitative level; (ii) organisational aspects, both on aspects of maturity of business processes (quantitative) and on aspects of the definition and application of procedures (qualitative). This paper shows the necessity for an analysis on all aspects in a safety certification process, and presents an overview of the available tools and techniques for the various quadrants. As methods and tools for especially quadrant C are currently unavailable, this paper will propose a method to assess and improve the maturity of an organisation on reliability management: the maturity index on reliability (MIR)

    Hamel, A.; St-Jean, G.

    1992-01-01

    This paper presents an analysis of stresses applied to two actual types of station class surge arresters of the same voltage rating when tested for durability as prescribed by American (ANSI) International (IEC) and Canadian (CSA) standards for 315 kV and 734 kV power systems. The analysis which is made with an experimentally validated arrester model, reveals that the IEC duty cycle test is the most severe of all. In fact it can bring the varistors of an actual station-type arrester to a peak temperature of 129 degrees C, which leaves a margin of only 46 degrees C to its thermal stability limit at maximum continuous operating voltage (MCOV). Another actual arrester using lesser V-I-T varistor characteristics but larger varistor volume and better heat transfer from inside to outside the arrester, produces 103 degrees C which corresponds to a slightly better temperature margin of 49 degrees C. It is observed that even when using the lower performance V-I-T characteristics of the latter arrester, a thin-wall arrester housing design can improve heat transfer to a point where the margin improves to 101 degrees C on a hypothetical arrester

    The public institution aims to promote excellence in public management to contribute to the quality of services provided to its customers and to increase competitiveness in the country, as well as its international projection. A technical barrier to trade that can lead to dissatisfaction and achieve the reputation of the institution is failing the test or calibration results and measurement data, thereby accreditation is regarded as the first essential step to facilitate the mutual acceptance of test results and calibration or measurement data. For recognition, laboratories need to demonstrate full compliance with both the sections of ISO/IEC 17025:2005, i.e. management and technical requirements. This research aims to discuss the critical aspects for implementation of ABNT NBR ISO / IEC 17025:2005 for calibration and testing of a Public Institution seeking accreditation of its laboratories with INMETRO, national accreditation body Laboratories. Besides getting preventive, corrective and improvement actions continues guidelines. Furthermore, the methodology used was to conduct a literature search and apply a questionnaire to identify the degree of agreement / disagreement of the foundations of the standard servers. Analysis of the results showed that the critical issues were: commitment, training, resources (infrastructure, human) and culture. (author)

  14. Combining ISO/IEC 17025:2005 and European Commission Decision 2002/657 audit requirements: a practical way forward.

    Laboratories involved in the analyses of veterinary drug residues are under increasing pressure to demonstrate that they produce meaningful and reliable data. Quality assurance and quality control systems are implemented in laboratories to provide evidence of this and these are subject to external assessment to ensure that they are effective. Audits to ISO/IEC 17025:2005, an internationally accepted standard, and subsequent accreditation provide laboratories and their customers with a degree of assurance that the laboratories are operating in control and the data they report can be relied on. However, national or regional authorities may place additional requirements on laboratories to ensure quality data are reported. For example, in the European Union, all official control laboratories involved in veterinary drug residue analyses must also meet the requirements of European Commission Decision 2002/657/EC which sets performance criteria for analytical methods used in this area and these are subject to additional audits by national or regional authorities. All audits place considerable time and resource demands on laboratories and this paper discusses the burden audits place on laboratories and describes a UK initiative to combine these audits to the benefit of both the regulatory authority and the laboratory. © 2012 John Wiley & Sons, Ltd.

    2010-04-01

    The international standard IEC 62220-1-2 defines the measurement procedure for determination of the detective quantum efficiency (DQE) of digital x-ray imaging devices used in mammography. A mobile setup complying to this standard and adaptable to most current systems was constructed in the Helmholtz Zentrum München to allow for an objective technical comparison of current full field digital mammography units employed in mammography screening in Germany. This article demonstrates the setup's capabilities with a focus on the measurement uncertainties of all quantities contributing to DQE measurements. Evaluation of uncertainties encompasses results from measurements on a Sectra Microdose Mammography in clinical use, as well as on a prototype of a Fujifilm Amulet system at various radiation qualities. Both systems have a high spatial resolution of 50 μm × 50 μm. The modulation transfer function (MTF), noise power spectrum (NPS) and DQE of the Sectra MDM are presented in comparison to results previously published by other authors.

    2014-01-01

    Full Text Available Recent studies have demonstrated that wheat peptides protected rats against non-steroidal anti-inflammatory drugs-induced small intestinal epithelial cells damage, but the mechanism of action is unclear. In the present study, an indomethacin-induced oxidative stress model was used to investigate the effect of wheat peptides on the nuclear factor-κB(NF-κB-inducible nitric oxide synthase-nitric oxide signal pathway in intestinal epithelial cells-6 cells. IEC-6 cells were treated with wheat peptides (0, 125, 500 and 2000 mg/L for 24 h, followed by 90 mg/L indomethacin for 12 h. Wheat peptides significantly attenuated the indomethacin-induced decrease in superoxide dismutase and glutathione peroxidase activity. Wheat peptides at 2000 mg/L markedly decreased the expression of the NF-κB in response to indomethacin-induced oxidative stress. This study demonstrated that the addition of wheat peptides to a culture medium significantly inhibited the indomethacin-induced release of malondialdehyde and nitrogen monoxide, and increased antioxidant enzyme activity in IEC-6 cells, thereby providing a possible explanation for the protective effect proposed for wheat peptides in the prevention of indomethacin-induced oxidative stress in small intestinal epithelial cells.

Compared to the previous edition, especially the extreme load determination has been modified by applying stochastic and statistical analyses. Within this paper the effect on the overall load level of wind turbines is demonstrated and occurring problems are discussed. Load simulations have been carried out for four state-of-the-art multi-megawatt wind turbines of different design concepts and from different manufacturers. The blade root bending moments and tip deflection have been determined by applying different extrapolation methods. Advantages and disadvantages of these methods and tail fittings for different load components and wind turbine technologies are discussed and interpreted. Further on, the application of the extreme turbulence model is demonstrated. The dependence of the load level on the turbulence intensity and control system, as well as the interaction with extrapolated loads is discussed and limitations outlined. The obtained load level is compared to the overall load level of the turbines according to the previous edition of the standard, IEC 61400-1:1999

    2011-01-01

    The seismic qualification of safety related equipment in nuclear power plants should demonstrate an equipment's ability to perform its safety function during/or after the time it is subjected to the forces resulting from one SSE. In addition, the equipment must withstand the effects of a number of OBEs, preceding the SSE. IEEE 344 and IEC 60980 present the criteria for establishing procedures demonstrating that the Class 1E equipment can meet its performance requirement during seismic events. Currently, IEEE 344 is used for regulation of nuclear power plant in the United State whereas IEC 60980 is mainly used in Europe. In particular, NPPs of France and China apply with RCC-E and GB that are domestic standards, respectively. Equipment supplier and Utility have difficulties because of different applicable standards. Equipment supplier to export S/R components/equipment to other standard area performs additional seismic qualification. For example, equipment are qualifies according to IEC 60980, RCC-E, GB although they have been qualified in accordance with IEEE 344. Also, utility to attempt power up-rate, life extension of NPP constructed under rules of RCC-E such as Ulchin NPP 1 and 2 has similar difficulties. RCC-E endorses IEC 60980 and GB is almost same as IEC 60980 except minor difference of earthquake environment definition. Therefore this paper surveys the similarities and differences between IEEE 344 and IEC 60980. In addition, this paper considers how the two sets of standards may be used in a complementary fashion to be possible using one or the other standard area

    Efficient permanent-magnet motors achieve in the area up to 100 kW a higher efficiency than induction machines (standard motors). A simple and fast energy saving option is the exchange of inefficient standard motors. The objective of this work is to install a 3 kW permanent-magnet motor in a standard IEC housing and the optimization of the design for high efficiency. Another objective is the development and the realization of an efficient variable speed control. The efficiency of the motor and the inverter with the control system must be demonstrated by tests. These tasks have been split between Circle Motor AG and the universities of applied sciences of Valais and Lucerne. Considering high-efficiency and low manufacturing cost, a brushless DC solution was adopted. This resulted in an optimum design of the motor and the control system realized with a three-phase rectifier, a buck converter with variable DC voltage, and a three-phase inverter feeding full positive and negative current to two of the legs simultaneously. The maximum measured efficiency is about 96.5% for the inverter and 92% for the motor. With the advantage of the variable speed operation, the efficiency of the realized 3 kW permanent magnet motor together with the control system is always higher than the efficiency of a measured class EFF1 induction motor, even with a direct connection to the grid. The permanent-magnet motor is also about 10 kg lighter. The cost calculation shows that the permanent-magnet motor can be competitive with the induction motor when speed control is desired. This is also the domain with the largest potential for energy savings from variable speed pumps, compressors, fans. (author)

  18. Model-driven design using IEC 61499 a synchronous approach for embedded and automation systems

    CERN Document Server

    Yoong, Li Hsien; Bhatti, Zeeshan E; Kuo, Matthew M Y

    2015-01-01

    This book describes a novel approach for the design of embedded systems and industrial automation systems, using a unified model-driven approach that is applicable in both domains.  The authors illustrate their methodology, using the IEC 61499 standard as the main vehicle for specification, verification, static timing analysis and automated code synthesis.  The well-known synchronous approach is used as the main vehicle for defining an unambiguous semantics that ensures determinism and deadlock freedom. The proposed approach also ensures very efficient implementations either on small-scale embedded devices or on industry-scale programmable automation controllers (PACs). It can be used for both centralized and distributed implementations. Significantly, the proposed approach can be used without the need for any run-time support. This approach, for the first time, blurs the gap between embedded systems and automation systems and can be applied in wide-ranging applications in automotive, robotics, and industri...

  19. Harnessing ISO/IEC 12207 to Examine the Extent of SPI Activity in an Organisation

    Science.gov (United States)

    Clarke, Paul; O'Connor, Rory

    The quality of the software development process directly affects the quality of the software product. To be successful, software development organisations must respond to changes in technology and business circumstances, and therefore software process improvement (SPI) is required. SPI activity relates to any modification that is performed to the software process in order to improve an aspect of the process. Although multiple process assessments could be employed to examine SPI activity, they present an inefficient tool for such an examination. This paper presents an overview of a new survey-based resource that utilises the process reference model in ISO/IEC 12207 in order to expressly and directly determine the level of SPI activity in a software development organisation. This survey instrument can be used by practitioners, auditors and researchers who are interested in determining the extent of SPI activity in an organisation.

    Full Text Available Information security should be today a key issue in any organization. With the implementation of information security management system (ISMS the organization can identify and reduce risks in this area. This the area of information security management covers a numbers of ISO / IEC 27000 standards, which are based on best practice solutions. However, smaller organizations are often discourages with the implementation of these systems, because of fear of high cost and complexity. Especially due to the fact that the standards does not strictly require implementation of all security controls it is possible to implement these systems in small-size organizations. In this article, we want to point on this fact through describing practical experience with ISMS implementation in small-size organization.

    Purpose Patchouli alcohol (PA) is used to treat gastrointestinal dysfunction. The purpose of this study was to ascertain the function of PA in the regulated process of oxidative stress in rat intestinal epithelial cells (IEC-6). Materials and methods Oxidative stress was stimulated by exposing IEC-6 cells to heat shock (42 °C for 3 h). IEC-6 cells in treatment groups were pretreated with various concentrations of PA (10, 40, and 80 ng/mL) for 3 h before heat shock. Results Heat shock caused damage to the morphology of IEC-6 cells, and increased reactive oxygen species (ROS) level and malondialdehyde (MDA) content. Moreover, mRNA and protein expression by target genes related to oxidative stress in heat shock were also altered. Specifically, the mRNA expression by HSP70, HSP90, GSH-px, NRF2 nd HO-1were all increased, and Nrf2 and Keap1 protein expression were increased after heat shock. However, pretreatment with PA weakened the level of damage to the cellular morphology, and decreased the MDA content caused by heat shock, indicating PA had cytoprotective activities. Pretreatment with PA at high dose significantly increased generation of intracellular ROS. Compared with the heat shock group alone, PA pretreatment significantly decreased the mRNA expression by HSP70, HSP90, SOD, CAT, GSH-px, KEAP1 and HO-1. Furthermore, the high dose of PA significantly increased Nrf2 protein expression, while both the intermediate and high dose of PA significantly increased HO-1 protein expression. Conclusion Heat-shock-induced oxidative stress in IEC-6 cells, and PA could alleviate the Nrf2-Keap1 cellular oxidative stress responses.

    The IEC norm 60034-30 defines new international standards for efficiency of electric motors. IE1 is standard efficiency, IE2 is high efficiency, and IE3/IE4 are the premium class. Circle Motor AG assumes that the premium class efficiency factor for motors with power less than 22 kW is easier to achieve with Permanent-Magnet-Motors enhanced by electric inverters than with asynchronous motors. The goal of this work is to achieve an overall 'efficiency factor' of 90% through a high-efficiency 3 kW-rated input Permanent-Magnet-Motor enhanced with an electric inverter, and then to perform measurements on the pump drive. The 'efficiency factor' measurement results showed worse performance than expected for both the inverter and the motor. One reason is due to high iron losses in the motor that are produced by high frequency currents of inverter. Another reason is the relatively high ohmic resistance of the copper motor winding caused by the chosen coil production method. By filtering high frequency currents at the rated power, the motor efficiency factor reaches up to 89.5%, which complies with premium class IE3. In generator mode the efficiency reaches 92.8%. We note that the positive result of this work is that the inverter can be produced with very low standby power losses - in our current work with 160 mW. It is necessary to admit that every detail can be responsible for success or failure during research and development activities of premium class motors. The optimization activities mainly belong to the area of additional losses of electric machines. In this report we have encountered all research results on the theme of Additional Losses that resulted from the current research work. The concept of drive control from the previous research project has shown itself as efficiency aware. The total efficiency factor of 90% can be reached by a system coupling a drive controller with a synchronous motor and the 'know how' from this work. The

  14. Development of an international standard on instruments setpoints based on ISA S67.04 - 1994

    International Nuclear Information System (INIS)

    Quinn, E.L.

    1996-01-01

    This is a summary of the application for and development of an international standard on instrument setpoints, based on the Instrument Society of America (ISA) Standard S67.04 - 1994. The forum this new standard was proposed in is the International Electrotechnique Commission (IEC), based in Geneva, Switzerland, which is the international commission which oversees electrical and instrumentation standards for all applications around the world. The Instrument Society of America (ISA) is a United States based Society for the advancement of instrumentation and controls related science and technology and has 30,000 members. A division within the ISA is the Standard and Practices board which has over 5000 members actively involved in standards development and approval. In 1994, the ISA SP67, Nuclear Power Plant Standards Committee authorized that the IEC be approached to develop and issue an IEC standard on Instrument Setpoints. This application was formally submitted in January, 1995 to the IEC and approved for ballot to member countries in June, 1995. Approval for standard development by IEC was received in October, 1995 and the first draft vas issued in February, 1996, and is currently under review by the IEC working group. It is very important to focus on the approach that the U.S. and other countries are taking toward development of IEC standards that can apply to all nuclear instrumentation applications around the world. By referencing IEC standards in design specification, vendors can be solicited from many different countries, thereby ensuring that the highest quality products can be used. This also offsets the need to specify individual standards in the specification, based on the country that each vendor solicited, represents. In summary, this standard development process, with support from the American National Standards Institute (ANSI) will assist U.S. suppliers in competing in the global market for products and services into the next century.

    2011-01-01

    The ultrasonic power measurement, worldwide accepted, standard is the IEC 61161, presently in its 2nd edition (2006), but under review. To fulfil its requirements, considering that a radiation force balance is to be used as ultrasonic power detector, a large amount of raw data (mass measurement) shall be collected as function of time to perform all necessary calculations and corrections. Uncertainty determination demands calculation effort of raw and processed data. Although it is possible to be undertaken in an old-fashion way, using spread sheets and manual data collection, automation software are often used in metrology to provide a virtually error free environment concerning data acquisition and repetitive calculations and corrections. Considering that, a fully automate ultrasonic power measurement system was developed and comprehensively tested. A 0,1 mg of precision balance model CP224S (Sartorius, Germany) was used as measuring device and a calibrated continuous wave ultrasound check source (Precision Acoustics, UK) was the device under test. A 150 ml container filled with degassed water and containing an absorbing target at the bottom was placed on the balance pan. Besides the feature of automation software, a routine of power measurement simulation was implemented. It was idealized as a teaching tool of how ultrasonic power emission behaviour is with a radiation force balance equipped with an absorbing target. Automation software was considered as an effective tool for speeding up ultrasonic power measurement, while allowing accurate calculation and attractive graphical partial and final results.

    2017-02-01

    Full Text Available Nowadays, factory automation systems need to cope with very different challenges, such as big data, IIoT, etc. These challenges lead to a new generation of automation systems based on the so-called Cyber-Physical Production Systems (CPPS globally connected to form a flexible System of Cyber-Physical Production Systems (SoCPPS. CPPSs require acquisition of production system data and smart data processing to extract information to improve the overall system performance. To achieve that it is needed to bridge the gap between the control systems and higher layers. This paper discusses an approach to use the IEC 61499 function block concept to exchange data between plant floor and higher layers using an industrial standard like OPC UA. The OPC UA server offers subscription mechanisms, making possible the integration of several resources residing at plant floor. As it runs on embedded devices, the proposal makes possible to acquire plant information at low cost, enabling at the same time, a component-based design for enterprise plant floor control with independence of the hardware platform used

    The purpose of this study was to establish the standard RQT radiation qualities which represent simulations of the unattenuated beam used in Computed Tomography (CT). Thus, to avoiding excessive efforts for establishing a radiation quality by means of the spectral distribution of the photon fluence, the characterization of these standard radiation qualities was expressed in terms of the X-ray tube voltage, first and second half-value layer (HVL). To establishing the standard radiation beam, according to the IEC 61267 and the TRS 457 was measured first of all the correct values of the X ray tube voltages in terms of Practical Peak Voltage. The standard radiation qualities RQT were produced using the same set up mounted for the RQR qualities which had been early established, and for simulating the patient in order to achieve the standard RQT series, suitable thicknesses of layers of copper were used to obtain the values of the first HVL according to IEC 61267.

    Essential oils from Pinus species have been reported to have various therapeutic properties. This study was undertaken to identify the chemical composition and cytoprotective effects of the essential oil of Pinus halepensis L. against aspirin-induced damage in cells in vitro. The cytoprotection of the oil against toxicity of aspirin on the small intestine epithelial cells IEC-6 was tested. The obtained results have shown that 35 different compounds were identified. Aspirin induced a decrease in cell viability, and exhibited significant damage to their morphology and an increase in superoxide dismutase (SOD) and catalase (CAT) activities. However, the co-treatment of aspirin with the essential oil of Pinus induced a significant increase in cell viability and a decrease in SOD and CAT activities. Overall, these finding suggest that the essential oil of Pinus halepensis L. has potent cytoprotective effect against aspirin-induced toxicity in IEC-6 cells.

    With the publication and enforcement of the standard IEC 61508 of safety related systems, recent system architectures have been presented and evaluated. Among a number of techniques and measures to the evaluation of safety integrity level (SIL) for safety-related systems, several measures such as reliability block diagrams and Markov models are used to analyze the probability of failure on demand (PFD) and mean time to failure (MTTF) which conform to IEC 61508. The current paper deals with the quantitative analysis of the novel 1oo4-architecture (one out of four) presented in recent work. Therefore sophisticated calculations for the required parameters are introduced. The provided 1oo4-architecture represents an advanced safety architecture based on on-chip redundancy, which is 3-failure safe. This means that at least one of the four channels have to work correctly in order to trigger the safety function.

    This paper describes and promotes the adoption of ISO 9712: 2005 edition and the ISO/IEC 17024: 2003 edition by the Philippines to be globally competitive. ISO 9712 is a standard for qualifications and certification of nondestructive testing (NDT) personnel while ISO/IEC 17024 is conformity assessment-general requirements for bodies operating certification of persons. ISO 9712 defies that the effectiveness of an application of nondestructive testing depends on the capabilities and qualifications of personnel performing the NDT test. The Philippines through the national certifying body (NCB) implements the certification of proficiency of NDT personnel in accordance with the Philippine National Standards (PNS-146: 1998) This standard (formerly PNS-146: 1987) was originally based from the draft ISO/TC-135/SC7N35.3 and was later revised to conform to the latest ISO FDIS 9712: 1997 and rename PNS-146: 1998. Now with the issuance of the latest ISO 9712:2005 edition and to keep abreast with the current trends of NDT technology, present time and conditions dictates for us to revise our NDT personnel certification to the latest edition of ISO 9712. The International Atomic Energy Agency (IAEA) supports the establishment of a common NDT standard. The IAEA is promoting af financially supporting the establishment in developing countries of only one NDT standard. The IAEA through the Regional Cooperative Agreement (RCA) has initiated the harmonization of the NDT qualification and certification of personnel in the RCA member states. In October 2001, the IAEA sponsored the Dhaka meeting where the International Committee for Nondestructive Testing (ICNDT), Asia-Pacific Committee (APCNDT) and RCA member states representatives drafted a Mutual Recognition Agreement (MRA) for the Asia-Pacific NDT (APCNDT) personnel certification schemes acording to ISO 9712. Last August 2005, IAEA/RCA sponsored the Colombo meeting for the harmonization of regional NDT applying ISO 9712 and ISO/IEC

    Aspirin, one of the widely used nonsteroidal anti-inflammatory drugs, is the most highly consumed pharmaceutical product in the world. However, it has several side effects in cells. This study was designed to investigate the antioxidative activity and cytoprotective effects of essential oil of Citrus limon (EOC) extracted from leaves against aspirin-induced damages in the rat small intestine epithelial cells (IEC-6). Biochemical indicators were used to assess cytotoxicity and oxidative damages caused by aspirin treatment on IEC-6. Our results showed that the chemical characterization of EOC identified 25 compounds representing 98.19% of the total oil. The major compounds from this oil were z-citral (53.21%), neryl acetate (13.06%), geranyl acetate (10.33%), and limonene (4.23%). Aspirin induced a decrease in cell viability as well as an increase in superoxide dismutase (SOD) and catalase (CAT) activities. Contrariwise, the co-exposure of cells to aspirin and EOC alleviated every above syndrome by an increase in cell survival and decrease in SOD and CAT activities. In conclusion, the essential oil of C. limon has a potent cytoprotective effect against aspirin-induced toxicity in IEC-6 cells.

    The main goal of this work is to establish the radiation qualities of the Laboratório de Ciências Radiológicas (LCR) conventional X-ray equipment for calibrations in radiodiagnostics according to the recommendations of IEC 61267 and TRS 457. Tests were conducted to evaluate the homogeneity of the radiation field, high voltage applied to the X-ray tube, scattering, half-value layers (HVL) and homogeneity coefficients. The results obtained that characterize the radiation field, satisfy the conditions required by TRS 457. Invasive high voltage measures presented results compatible with the requirements of this standard. The HVL measures showed that for the first HVL the tolerance limits of IEC 61267, and the values for the homogeneity coefficients were within the limits established. The quality tests performed in this work were highly satisfactory in meeting the standard requirements. Thus, the main goal was achieved, and the methodology can be used by other similar X-ray systems. - Highlights: • Establishment the radiation qualities for X-ray calibrations in radiodiagnostics. • Comparison to kV between invasive and noninvasive method. • Determination of additional filtrations suggested by IEC 61267. • Determination of the radiation scattered by the experimental setup as TRS 457. • Determination of HVLs as TRS 457.

    Highlights: • UPR activation precedes caspase activation in irradiated IEC-6 cells. • Chemical ER stress inducers radiosensitize IEC-6 cells. • siRNAs that targeted ER stress responses ameliorate IR-induced cell death. • Chemical chaperons prevent cell death in irradiated IEC-6 cells. - Abstract: Radiotherapy, which is one of the most effective approaches to the treatment of various cancers, plays an important role in malignant cell eradication in the pelvic area and abdomen. However, it also generates some degree of intestinal injury. Apoptosis in the intestinal epithelium is the primary pathological factor that initiates radiation-induced intestinal injury, but the mechanism by which ionizing radiation (IR) induces apoptosis in the intestinal epithelium is not clearly understood. Recently, IR has been shown to induce endoplasmic reticulum (ER) stress, thereby activating the unfolded protein response (UPR) signaling pathway in intestinal epithelial cells. However, the consequences of the IR-induced activation of the UPR signaling pathway on radiosensitivity in intestinal epithelial cells remain to be determined. In this study, we investigated the role of ER stress responses in IR-induced intestinal epithelial cell death. We show that chemical ER stress inducers, such as tunicamycin or thapsigargin, enhanced IR-induced caspase 3 activation and DNA fragmentation in intestinal epithelial cells. Knockdown of Xbp1 or Atf6 with small interfering RNA inhibited IR-induced caspase 3 activation. Treatment with chemical chaperones prevented ER stress and subsequent apoptosis in IR-exposed intestinal epithelial cells. Our results suggest a pro-apoptotic role of ER stress in IR-exposed intestinal epithelial cells. Furthermore, inhibiting ER stress may be an effective strategy to prevent IR-induced intestinal injury.

    2013-02-01

    Full Text Available [english] IEC 80001-1 is an international standard and offers recommendations for a risk management process for medical information technology networks (MITs. MITs are defined as IT networks incorporating at least one medical device. The goal is to build and maintain reliable and secure MITs for hospitals of all kids. To achieve it, the standard suggests applying risk management and defines the roles involved as well as their responsibilities. A central role is the medical IT-network risk manager, assigned by the top management of organizations. He communicates with and mediates between clinical, medical device and IT divisions and compiles risk relevant facts usually distributed among them. All identified risks are analyzed, evaluated and documented in the risk management file along with counter measures and a final assessment of acceptability.We acknowledge that implementing the suggested process will create an overhead cost in documentation and – partly by extension – in personnel. However we believe that the investment at the start of projects is worthwhile, because it helps to prevent or solve problems in later stages. Especially consecutive projects can profit from the investment, reducing required effort and costs. Furthermore, a reliable and secure MIT forms the basis for frictionless routine operations and innovations for connected medical devices. Hence the investment is justified. Applying risk management to the whole cooperation all at once is unrealistic. Focusing on parts of the network, which are crucial to a new project is more recommendable. With a smaller scope, risk management remains feasible and can later be expanded to other parts of the network.IEC 80001-1 demands communication among involved employees from different specialties and divisions. This offers a chance for cooperation to find better decisions and solutions regarding an organization’s medical IT network.[german] Die IEC 80001-1 ist eine Norm, die

    Boris, D. R.; Emmert, G. A.

    2007-11-01

    The ion source region of the UW-Inertial Electrostatic Confinement device is comprised of a filament assisted DC discharge plasma that exists between the wall of the IEC vacuum chamber and the grounded spherical steel grid that makes up the anode of the IEC device. A 0-dimensional rate equation calculation of the molecular deuterium ion species concentration has been applied utilizing varying primary electron energy, and neutral gas pressure. By propagating ion acoustic waves in the source region of the IEC device the concentrations of molecular deuterium ion species have been determined for these varying plasma conditions, and high D3^+ concentrations have been verified. This was done by utilizing the multi-species ion acoustic wave dispersion relation, which relates the phase speed of the multi-species ion acoustic wave, vph, to the sum in quadrature of the concentration weighted ion acoustic sound speeds of the individual ion species.

    The igf1 gene is alternatively spliced as IGF-IEa and IGF-IEc variants in humans. In fibrostenotic Crohn's disease, the fibrogenic cytokine TGF-β1 induces IGF-IEa expression and IGF-I production in intestinal smooth muscle and results in muscle hyperplasia and collagen I production that contribute to stricture formation. Mechano-growth factor (MGF) derived from IGF-IEc induces skeletal and cardiac muscle hypertrophy following stress. We hypothesized that increased IGF-IEc expression and MGF production mediated smooth muscle hypertrophy also characteristic of fibrostenotic Crohn's disease. IGF-IEc transcripts and MGF protein were increased in muscle cells isolated from fibrostenotic intestine under regulation by endogenous TGF-β1. Erk5 and MEF2C were phosphorylated in vivo in fibrostenotic muscle; both were phosphorylated and colocalized to nucleus in response to synthetic MGF in vitro. Smooth muscle-specific protein expression of α-smooth muscle actin, γ-smooth muscle actin, and smoothelin was increased in affected intestine. Erk5 inhibition or MEF2C siRNA blocked smooth muscle-specific gene expression and hypertrophy induced by synthetic MGF. Conditioned media of cultured fibrostenotic muscle induced muscle hypertrophy that was inhibited by immunoneutralization of endogenous MGF or pro-IGF-IEc. The results indicate that TGF-β1-dependent IGF-IEc expression and MGF production in patients with fibrostenotic Crohn's disease regulates smooth muscle cell hypertrophy a critical factor that contributes to intestinal stricture formation.

    A rapid, simple and sensitive multi-residue method was developed and validated for the simultaneous quantification and confirmation of 69 pesticides in fruit and vegetables using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The samples were extracted following the quick, easy, cheap, effective, rugged and safe method known as QuEChERS. Mass spectrometric conditions were individually optimised for each analyte in order to achieve maximum sensitivity in multiple reaction monitoring (MRM) mode. Using the developed chromatographic conditions, 69 pesticides can be separated in less than 17 min. Two selected reaction monitoring (SRM) assays were used for each pesticide to obtain simultaneous quantification and identification in one run. With this method in SRM mode, more than 150 pesticides can be analysed and quantified, but their confirmation is not possible in all cases according to the European regulations on pesticide residues. Nine common representative matrices (zucchini, melon, cucumber, watermelon, tomato, garlic, eggplant, lettuce and pepper) were selected to investigate the effect of different matrices on recovery and precision. Mean recoveries ranged from 70% to 120%, with relative standard deviations (RSDs) lower than 20% for all the pesticides. The proposed method was applied to the analysis of more than 2000 vegetable samples from the extensive greenhouse cultivation in the province of Almeria, Spain, during one year. The methodology combines the advantages of both QuEChERS and LC-MS/MS producing a very rapid, sensitive, accurate and reliable procedure that can be applied in routine analytical laboratories. The method was validated and accredited according to UNE-EN-ISO/IEC 17025:2005 international standard (accreditation number 278/LE1027).

    The Electric Vehicle (EV) has properties that can not only load but can elevate its value as a resource to the power system. An EV represents a high-power, fast-responding flexible demand unit, with an attached energy storage (battery) and the potential for bi-directional capabilities (V2G......). These properties can be used in a number of power and energy services, which can support power system operation while lowering the cost of EV ownership. Such services depend on the support from the communications technologies and standards that connect controllers and logic in the EVs with those in the charging...... for smart charging - to gain this ability by simply adhering to the widely supported IEC61851 standard. This paper describes the solution, demonstrates the implementation and discusses the potential it has for unlocking EV power- and energy services....

    This work shows results of type testing of a ring dosimeter system under new IEC 62387:2012. The personal dosimeter investigated in this work consists of a commercial one element plastic ring (RADOS) which contains an LiF:Mg,Ti. By applying requirements for statistical fluctuations and linearity, a minimum measurable dose in Hp(0.07) was established. Energy and angular dependence aided in determining energy correction factors and fading requirements were used to select the most appropriate preheat scheme. Type testing of passive radiation monitors performed in the Radiation Metrology Laboratory (LMRI-DEN/UFPE) of the Federal University of Pernambuco is a major step in Brazil for the independent evaluation of these dosimeters, currently not available in the country.

    Oates, Phillip S; Thomas, Carla

    2005-08-01

    Absorption of iron occurs by duodenal enterocytes, involving uptake by the divalent metal transporter-1 (DMT1) and release by ferroportin. Ferroportin responds to the hepatocyte-produced 25-amino-acid-peptide hepcidin-25 by undergoing internalisation to late endosomes that impair iron release. Ferroportin is also expressed on the apical membrane of polarised Caco-2 cells, rat intestinal cells and in IEC-6 cells (an intestinal epithelial cell line). A blocking antibody to ferroportin also impairs the uptake, but not the release, of iron. In this study IEC-6 cells were used to study the mechanism of impairment or recovery from impairment produced by the blocking antibody and the fate of DMT1 and ferroportin. Uptake of 1 muM Fe(II) was studied by adding the antibody from time 0 and after adding or removing the antibody once a steady state had been reached. Surface binding, maximum iron transport rate V(max) and transporter affinity (K(m)) were measured after impairment of iron uptake. Ferroportin and DMT1 distribution were assessed by immunofluorescence microscopy. Antibody-mediated impairment, or recovery from impairment, of Fe(II) uptake occurred within minutes. Impairment was lost when the antibody was combined with the immunizing peptide. DMT1 and ferroportin undergo internalisation to late endosomes and, in the presence of the antibody, augmented internalisation of DMT1 and ferroportin caused swelling of late endosomes. Surface binding of Fe(II) and iron transport V(max) were reduced by 50%, indicating that the antibody removed membrane-bound DMT1. The ferroportin antibody induced rapid turnover of membrane ferroportin and DMT1 and its internalisation to late endosomes, resulting in impaired Fe(II) uptake.

    Binh Thanh District of Ho Chin Minh City in 1989 had a crude birth rate (CBR) of 20.3 per 1000 population and an average of 5.5 persons per household. The rate of total fertility (TFR) in the district was one of the highest among the city's 18 districts in 1990. Concerned about these demographics, the Binh Thanh District Committee for Population and Family Planning reviewed the family planning program with the goal of developing a special information, education, and communication (IEC) campaign. The following incentive scheme for sterilization was developed: each poor entrepreneur in need of seed money for new business ventures who allows himself to be sterilized receives dong 120,000 (US$11) from the National Committee for Population and Family Planning and dong 220,000 from the District Committee for Population and Family Planning to buy medicine and supplementary food. An IEC room was established in each commune health center to disseminate the relevant information. The results of the campaign have been positive, with 910 people requesting sterilization in 1994, 34% of whom were male. Over the period January-April 1995, the proportion of male sterilization increased dramatically, such that men accounted for 68% of the 153 people who underwent sterilization. The district now ranks the lowest among the 18 districts with regard to the percentage of couples with three children, the CBR is 15.3/1000, TFR is 2.15, the contraceptive prevalence rate is 68%, and sterilization is the fourth most popular method of contraception (13%) behind the IUD (37%), condom (30%), and oral pill (18.5%).

    1995-01-01

    The present material presents a CD+V draft report ''RBMK nuclear reactors: Proposals for instrumentation and control improvements to enhance safety and availability'' prepared by the Joint IEC/IAEA team during 1993-1995. Experience has demonstrated the need to improve the safety instrumentation of the RBMK type reactors using well proven modern technology. The working group identified the upgrades and changes of the highest priority based on the evaluation of the RBMK systems and the events where the instrumentation was found to be inadequate for safe operation. The subjects discussed in this document were not selected on a systematic basis but were selected by the IEC and IAEA experts as considered to be appropriate to the activities of the IEC and for which technical experience was available. The items identified therefore do not reflect any ranking of the safety issues or any priority or impact on safety of any of the measures were they to be implemented. Many important safety issued and areas where physical measures are required to improve safety have been omitted and indeed not even acknowledged in this document. The recommendations presented in the document differ from those normally produced by the IEC in the form of standards as they are of a transitory nature and some have already been overtaken by the continuing process of improvements to plant safety.

  19. A methodology for distinguishing divergent cell fates within a common progenitor population: adenoma- and neuroendocrine-like cells are confounders of rat ileal epithelial cell (IEC-18 culture

    2005-01-01

    Full Text Available Abstract Background IEC-18 cells are a non-transformed, immortal cell line derived from juvenile rat ileal crypt cells. They may have experimental advantages over tumor-derived gastrointestinal lineages, including preservation of phenotype, normal endocrine responses and retention of differentiation potential. However, their proclivity for spontaneous differentiation / transformation may be stereotypical and could represent a more profound experimental confounder than previously realized. We hypothesized that IEC-18 cells spontaneously diverge towards a uniform mixture of epigenetic fates, with corresponding phenotypes, rather than persist as a single progenitor lineage. Results IEC-18 cells were cultured for 72 hours in serum free media (SFM, with and without various insulin-like growth factor agonists to differentially boost the basal rate of proliferation. A strategy was employed to identify constitutive genes as markers of divergent fates through gene array analysis by cross-referencing fold-change trends for individual genes against crypt cell abundance in each treatment. We then confirmed the cell-specific phenotype by immunolocalization of proteins corresponding to those genes. The majority of IEC-18 cells in SFM alone had a loss in expression of the adenomatous polyposis coli (APC gene at the mRNA and protein levels, consistent with adenoma-like transformation. In addition, a small subset of cells expressed the serotonin receptor 2A gene and had neuroendocrine-like morphology. Conclusions IEC-18 cells commonly undergo a change in cell fate prior to reaching confluence. The most common fate switch that we were able to detect correlates with a down regulation of the APC gene and transformation into an adenoma-like phenotype.

  2. Present problems of standardization in nuclear instrumentation in Romania

    International Nuclear Information System (INIS)

    Purghel, Lidia

    2001-01-01

    The continuos development of nuclear techniques, based on international cooperation, led to the need for producing national and international standards referring to terminology, classification, technical characteristic, testing and calibration methods for nuclear instrumentation. The international standardization activity is organised in the frame of the well-known organization like IEC, ISO, ICRU, ICRP, IOLM, CENELEC, EFOMP, WHO. High advances were obtained in the standardization of the ionising radiation dosimetry in the frame of the International Commission for Radiation Units (ICRU) which started its works 1925. Romania is member of the International Electrotechnical Commission (IEC) from 1920 when its president was the formal member of Romanian Academy, professor Remus Radulet. Romania is effectively involved in standardization activities in the field nuclear instrumentation both as user and manufacturer of nuclear instrumentation. At national level the Technical Committee 45, as a branch of the Romanian Electrotechnical Committee is hosted by Horia Hulubei National Institute for Physics and Nuclear Engineering. The technical committee has the tasks of analysing the market, the regulations and the industry requirements and proposing new standards or revision for existing one. A table is given showing the number of IEC standards considered by TC 45, adopted RS - IEC standards (prepared/published) and planned for 2000/2001. Romania hosted IEC international plenary meetings in 1962 and 1974 and an IEC workshop 1997 with participation of specialists from USA, Sweden, Germany, France, Japan and Romania. As industry is striving to use more and more standard products, that means best quality and safety for less money, more than ever one have to convince the industry about the usefulness and specificity of the nuclear standards

  6. Post-translational inhibition of IP-10 secretion in IEC by probiotic bacteria: impact on chronic inflammation.

    Directory of Open Access Journals (Sweden)

    Gabriele Hoermannsperger

    Full Text Available BACKGROUND: Clinical and experimental studies suggest that the probiotic mixture VSL#3 has protective activities in the context of inflammatory bowel disease (IBD. The aim of the study was to reveal bacterial strain-specific molecular mechanisms underlying the anti-inflammatory potential of VSL#3 in intestinal epithelial cells (IEC. METHODOLOGY/PRINCIPAL FINDINGS: VSL#3 inhibited TNF-induced secretion of the T-cell chemokine interferon-inducible protein (IP-10 in Mode-K cells. Lactobacillus casei (L. casei cell surface proteins were identified as active anti-inflammatory components of VSL#3. Interestingly, L. casei failed to block TNF-induced IP-10 promoter activity or IP-10 gene transcription at the mRNA expression level but completely inhibited IP-10 protein secretion as well as IP-10-mediated T-cell transmigration. Kinetic studies, pulse-chase experiments and the use of a pharmacological inhibitor for the export machinery (brefeldin A showed that L. casei did not impair initial IP-10 production but decreased intracellular IP-10 protein stability as a result of blocked IP-10 secretion. Although L. casei induced IP-10 ubiquitination, the inhibition of proteasomal or lysosomal degradation did not prevent the loss of intracellular IP-10. Most important for the mechanistic understanding, the inhibition of vesicular trafficking by 3-methyladenine (3-MA inhibited IP-10 but not IL-6 expression, mimicking the inhibitory effects of L. casei. These findings suggest that L. casei impairs vesicular pathways important for the secretion of IP-10, followed by subsequent degradation of the proinflammatory chemokine. Feeding studies in TNF(DeltaARE and IL-10(-/- mice revealed a compartimentalized protection of VSL#3 on the development of cecal but not on ileal or colonic inflammation. Consistent with reduced tissue pathology in IL-10(-/- mice, IP-10 protein expression was reduced in primary epithelial cells. CONCLUSIONS/SIGNIFICANCE: We demonstrate segment

    Nuclear power plant (NPP) and other nuclear installations have been recognized as applications needing very sophisticated technologies. One of technologies used in this all nuclear facilities is nuclear instrumentation. In order that NPP and other nuclear installations be operated safely, nuclear instrumentation requires standardization from design to its operation. Internationally, standardizations of nuclear instrumentation have been issued by IEC (International Electrotechnical Commission). Formulation of standard in nuclear instrumentation in IEC is carried out by Technical Committee (TC) 45. This paper describes briefly the standardization of nuclear instrumentation applied in Indonesia as Indonesian National Standard (SNI, Standard National Indonesia), standardization of nuclear instrumentation developed by TC 45, SC 45A, and SC 45B, as well as the possibility to adopt and apply those IEC standard in Indonesia

  10. IEC 61267: Feasibility of type 1100 aluminium and a copper/aluminium combination for RQA beam qualities.

    Science.gov (United States)

    Leong, David L; Rainford, Louise; Zhao, Wei; Brennan, Patrick C

    2016-01-01

    In the course of performance acceptance testing, benchmarking or quality control of X-ray imaging systems, it is sometimes necessary to harden the X-ray beam spectrum. IEC 61267 specifies materials and methods to accomplish beam hardening and, unfortunately, requires the use of 99.9% pure aluminium (Alloy 1190) for the RQA beam quality, which is expensive and difficult to obtain. Less expensive and more readily available filters, such as Alloy 1100 (99.0% pure) aluminium and copper/aluminium combinations, have been used clinically to produce RQA series without rigorous scientific investigation to support their use. In this paper, simulation and experimental methods are developed to determine the differences in beam quality using Alloy 1190 and Alloy 1100. Additional simulation investigated copper/aluminium combinations to produce RQA5 and outputs from this simulation are verified with laboratory tests using different filter samples. The results of the study demonstrate that although Alloy 1100 produces a harder beam spectrum compared to Alloy 1190, it is a reasonable substitute. A combination filter of 0.5 mm copper and 2 mm aluminium produced a spectrum closer to that of Alloy 1190 than Alloy 1100 with the added benefits of lower exposures and lower batch variability.

    This paper discussed a time synchronization and dynamic multicast filtering procedure conducted on an IEC 61850 process bus. The Institute of Electrical and Electronic (IEEE) 1588 time synchronization and dynamic multicast filtering procedure was conducted at a substation equipped with non-conventional instrument transformers (NCIT) and intelligent circuit breakers. The process bus interconnected IEDs within a bay that included a real time sampled value (SV) measurement system. The system was designed to reduce the use of copper wiring and to eliminate high energy signal processes. Digitized sampled measured values were sent from the electronic instrument transformers to protect and control relays. A merging unit was used to enable the transmission of the digitized current and voltage measurements across an ethernet network. Two sampling rates were supplied for power system monitoring and protection applications. The merging units continuously sent sampling values of current and voltages acquired from primary equipment. Precision time protocol systems were discussed, and issues related to time synchronization were reviewed. A network topology was provided. 4 refs., 4 figs.

    2003-01-01

    Of all the techniques applicable to safety-related analyses, each one may be adaptable to some aspects of the system safety behavior. On the other hand, some of them can fit to analysis on one aspect of the system behavior concerning risk, but they do not always lead to the same results. Rouvroye and Brombacher made a comparison of these techniques and indicated that Markov and Enhanced Markov analysis techniques can cover most aspects of system's safety-related behavior. According to their conclusion, the Markov method is introduced to Part 6 of the standard IEC 61508 for quantitative analysis in this paper. The purpose is to present explanation in details for solutions given in the standard because there are not clear descriptions for many results and it is not easy for a safety engineer to find the clue. In addition, the down time t c1 shown in the standard is newly defined because it is the basis to get the results of average probability of failure on demand of system architectures and its meaning is not clearly explained. Through derivation, however, a discrepancy is found in the standard. From this point of view, new suggestions are proposed based on the results obtained

    2005-01-01

    Ice and wind loads on conductors and earth wires are the most important environmental factors for the mechanical design of overhead lines. This paper addressed the economic importance of long-term recording and measuring of weather data and provided details of their use according to a recent International Electrochemical Commission technical report (60826). The procedures used to calculate design weather loads by applying the Gumbal cumulative distribution function were outlined using data collected from Studnice in the Czech Republic, where ice loads have been measured since 1940. Based on the calculations, it was suggested that predicting ice loads based on a reduced number of years may lead to either under or over designing overhead lines. An example of ice load measurements and records showed that the standard deviation of maximum annual ice loads is large. Ice and wind load data from previous technical reports were presented. It was noted that the number of years with observations, the average value and the standard deviation are the necessary parameters for making the statistical analyses of design wind and ice loads. Information on cost of overhead lines in Norway was provided, as well as details of ice load recommendations currently used. It was estimated that the total price of the uncertainty in the design ice loads for the total electric overhead line network in Norway was $30 million, representing 10 per cent of the annual replacement value of the grid. It was concluded that long-term data acquisition of ice loads could reduce investment costs when design ice loads are too high, and also alleviate damage to transmission system and loss of supply due to ice storms when the design ice value is too low. 3 refs., 4 tabs., 4 figs

    Medium voltage (MV) cells have to respect standards (for example IEC ones (IEC TC 17C 2003 IEC 62271-200 High Voltage Switchgear and Controlgear-Part 200 1st edn)) that define security levels against internal arc faults such as an accidental electrical arc occurring in the apparatus. New protection filters based on porous materials are developed to provide better energy absorption properties and a higher protection level for people. To study the filter behaviour during a major electrical accident, a two-dimensional model is proposed. The main point is the use of a dedicated numerical scheme for a non-conservative hyperbolic problem. We present a numerical simulation of the process during the first 0.2 s when the safety valve bursts and we compare the numerical results with tests carried out in a high power test laboratory on real electrical apparatus

    A reliable dosimetry in diagnostic radiology is based on the traceability of calibrated and type-tested dosimeters in reference radiations that were established by the International Electrotechnical Commission (IEC). Metrology laboratories are expected to implement the reference radiations by reproducing the x-ray beam parameters within standard limits. This work shows the results of the implementation in the CDTN/CNEN-MG of the reference radiations for diagnostic radiology. The half value-layers and the homogeneity coefficients were determined for the primary (RQR), attenuated (RQA) and computerized tomography (RQT) x-ray beams. Results complied with the IEC limits which it means that the CDTN and the IEC reference radiations are similar and they can be used for calibration and type-testing of dosimeters to be used in diagnostic radiology.

    The paper aims to present a practical approach for testing laboratories to ensure the quality of their test results. It is based on the experience gained in assessing a large number of testing laboratories, discussing with management and staff, reviewing results obtained in national and international PTs and ILCs and exchanging information in the EA laboratory committee. According to EN ISO/IEC 17025, an accredited laboratory has to implement a programme to ensure the quality of its test results for each measurand. Pre-analytical, analytical and post-analytical measures shall be applied in a systematic manner. They shall include both quality control and quality assurance measures. When designing the quality assurance programme a laboratory should consider pre-analytical activities (like personnel training, selection and validation of test methods, qualifying equipment), analytical activities ranging from sampling, sample preparation, instrumental analysis and post-analytical activities (like decoding, calculation, use of statistical tests or packages, management of results). Designed on different levels (analyst, quality manager and technical manager), including a variety of measures, the programme shall ensure the validity and accuracy of test results, the adequacy of the management system, prove the laboratory's competence in performing tests under accreditation and last but not least show the comparability of test results. Laboratory management should establish performance targets and review periodically QC/QA results against them, implementing appropriate measures in case of non-compliance.

    2016-01-01

    In recent years dengue has been witnessed as an emerging public health problem. Therefore, the present study was undertaken in order to assess the knowledge, attitude, behaviour and practices (KABP) adopted by the society for its control and prevention. The changes in behaviour of community after imparting health education were also recorded to determine the effectiveness of information, education and communication (IEC) for dengue prevention and control in Jodhpur City of Rajasthan, India. A threefold study was conducted in Jodhpur City regarding KABP about dengue fever amongst the community. Out of 106 cases of dengue reported from Jodhpur City in the year 2008, only 20 households (HHs) could be located. Therefore, nine HHs around one dengue positive household were selected so as to cover the sample size of 200 HHs for eliciting information through structured recorded interview-schedule. Health education as provided through audiovisuals and group discussion etc. and resultant change in KABP was recorded again through interview of respondents from 100 households. Prevention from dengue mosquito bites through mats and liquid vaporizer was known to 32 and 22% HHs respectively. Inhabitants of 87% HHs preferred to visit private health facility, 85% of HHs were not aware about the symptoms of dengue, while74% HHs stated that dengue mosquito breeds in dirty water. Awareness about source of mosquito breeding and source reduction was found to be very poor, i.e. 3 and 13% which improved to 78 and 88% respectively after undertaking IEC activities. Being urban area, the economic condition and education level were somewhat similar and satisfactory in Jodhpur City. IEC resulted in significant improvement in knowledge about transmission, breeding habitats of mosquito transmitting dengue, source reduction and health treatment seeking behaviour at government facility. Through such mass awareness programmes in the communities, desired results in prevention and control of dengue

    Kersken, M.

    1997-01-01

    Despite the advantages of computer-assisted safety technology, there still is some uneasyness to be observed with respect to the novel processes, resulting from absence of a body of generally accepted and uncontentious qualification guides (regulatory provisions, standards) for safety evaluation of the computer codes applied. Warranty of adequate protection of the population, operators or plant components is an essential aspect in this context, too - as it is in general with reliability and risk assessment of novel technology - so that, due to appropriate legislation still missing, there currently is a licensing risk involved in the introduction of digital safety systems. Nevertheless, there is some extent of agreement within the international community and utility operators about what standards and measures should be applied for qualification of software of relevance to plant safety. The standard IEC 880/IEC 86/ in particular, in its original version, or national documents based on this standard, are applied in all countries using or planning to install those systems. A novel supplement to this standard, document /IEC 96/, is in the process of finalization and defines the requirements to be met by modern methods of software engineering. (orig./DG) [de

    Since 1953, the Electrotechnical Laboratory has undertaken absolute measurements of the activities of some radionuclides by means of the 4 {pi}{beta}l counting method and the coincidence method. The details of the counting methods used in our laboratory will be described. 1. 4 {pi}{beta} Counting Method - a bell type of 4 {pi}{beta} gas proportional counting apparatus was designed, and its counting characteristics were investigated, especially the dependence upon the counting gases. In measuring the activity, about 50 mg of the sample was taken on a thin film and then dried in the silica gel desiccator. One drop of a wetting solution was added on the dried sample so as to reduce the self-absorption, and the sample was dried again. The thin film was prepared through the procedure that synthetic resin (Kanevinyl-Rl 108 in cyclohexanon) spread over the water surface was taken up on the metal ring and then covered with very thin gold by means of the vacuum evaporating method. Sr{sup 80}-Y{sup 90}, Co{sup 60} and Cs{sup 137} were measured by the above procedure. The accuracies of the measurements were of the order of {+-} 2%. 2. 2 {pi} {alpha} Counting Method - The samples, RaD + E + F, U{sup 238} and Po{sup 210} were measured by means of the same apparatus as in the 4 {pi}{beta} counting method. The accuracies of the measurements were {+-}2, {+-}1 and {+-} 1% respectively. 3. Coincidence Counting Method - In the coincidence method, both {beta}-{gamma} and {gamma}-{gamma} counting methods were employed. A scintillation counter [Nal (Tl), 1'' {Phi} X 1''] was used as {gamma}-ray detector, and a GM counter as {beta}-ray detector. Recently, in order to examine the inherent difference between the 4 {pi} {beta} counting and the coincidence counting methods, instead of the GM counter, we devised a special type of the 4 {pi} {beta} proportional counter, which can also be used as 4 {pi} {beta} proportional counting apparatus independently, apart from the coincidence circuits

    Polyphenolic compounds gained interest in the pharmaceutical research area due to their beneficial properties. Herein, antioxidant and cytoprotective capacities of T. gallica extract on H 2 O 2 -challenged rat small intestine epithelial cells were investigated. To set stress conditions, IEC-6 cultures were challenged with numerous H 2 O 2 doses and durations. Then, 40μM H 2 O 2 during 4h were selected to assess the cytoprotective effect of different T. gallica extract concentrations. Oxidative parameters, measured through CAT and SOD activities as well as MDA quantification were assessed. In addition, the expression of possibly involved MAPKs was also valued. Main results reported that T. gallica was rich in polyphenols and exhibited an important antioxidant activity (DPPH Assay, IC 50 =6μgmL -1 ; ABTS + test, IC 50 =50μgmL -1 ; Fe-reducing power, EC 50 =100μgmL -1 ). The exposure of IEC-6 cultures to 40μM H 2 O 2 during 4h caused oxidative stress manifested by (i) over 70% cell mortality, (ii) over-activity of CAT (246%), (iii) excess in MDA content (18.4nmolmg -1 ) and (iiii) a trigger of JNK phosphorylation. Pretreatment with T. gallica extract, especially when used at 0.25μgmL -1 , restored cell viability to 122%, and normal cell morphology in H 2 O 2 -chalenged cells. In addition, this extract normalized CAT activity and MDA content (100% and 14.7nmolmg -1 , respectively) to their basal levels as compared to control cells. Furthermore, stopping cell death seems to be due to dephosphorylated JNK MAPK exerted by T. gallica bioactive compounds. In all, T. gallica components provided a cross-talk between regulatory pathways leading to an efficient cytoprotection against harmful oxidative stimulus. Copyright © 2017 Elsevier Masson SAS.

    The improvement of Human-Machine Interface (HMI) design for control rooms on nuclear power plants (NPP) has been accomplished world wide, especially after the TMI-2 accident. The design process and guidelines are standardized in IEC60964 and supplemental standards as international standard. However, technological update is required due to the increased use of computerized control and monitoring equipment and systems in control rooms on NPP in recent years. Standards are becoming more important for computerized control rooms because there is more freedom to design than conventional hardware based system. For computerized control rooms, standards for hardware and software of HMI systems should be also considered. Standards and guidelines for computerized control rooms on NPP have been developed recently in each body such as IEC, ISO, and IEEE etc. Therefore, reviewing these standards and guidelines related to control rooms design of NPP can be useful not only for revision of the international standards such as IEC60964, but also for users of the standards and guidelines. In this paper, we reviewed the international standards related to the design for control rooms, in the two aspects of HMI design and hardware and software design, considering the undergoing revision work and their application.

    Cordon, Rosely

    2003-07-01

    The low intensity laser therapy (LILT) has been extensively used in medicine and dentistry presenting positive effects. However, the laser radiation can also cause adverse effects. Due to the ocular focalization property, in the wavelength from 400 to 1400 nm, the retina is more susceptible to damage by radiation than any other part of the human body. Then, the ocular protection is frequently emphasized. This protection must attenuate the radiation to a safe level. The International Electrotechnical Commission (IEC) standard IEC 60825-1 suggests safety requirements for medical laser equipment, including the ocular protection, based on maximum permissible exposure levels. The Brazilian legislation adopts a corresponding IEC standard, the NBR IEC 601.2.22, for safety requirements. The aim of this study was to analyze the adequacy of the ocular protectors furnished by four laser equipment manufacturers, commercially available in Brazil, commonly used for LILT. For this purpose, the laser equipment and the respective ocular protectors were characterized. The adequacy was verified according to the IEC standards. It was found, among other results, ocular protectors attenuating to safe levels the radiation emitted by the respective laser equipment, however, presenting inadequate visual transmission. Inefficient protection and protection indicated in cases where they were not necessary were also observed. (author)

    The purpose of this study is to evaluate exposure to radiofrequency (RF) radiation during magnetic resonance imaging (MRI) examinations. Particularly, in this paper, the authors compared the measuring procedures of a whole body specific absorption rate (SAR) set forth in two safety guidelines respectively: the safety guideline of MRI equipments in Japan which based on the 1988 guideline of the Food and Drug Administration (FDA), and the 1995 standard of the International Electrotechnical Commission (IEC). As a result of the measurement, the measuring procedure set forth in the Japanese guideline underestimated the whole body SAR of a torso phantom in a tuneless type QD coil. The result of our experiment clearly showed that the measuring procedure set forth in the Japanese guideline did not adjust to the tuneless type QD coil. Therefore, the authors recommended ''the pulse energy method'' which is provided by the IEC standard as a measuring procedure of the whole body SAR. (author)

    In the Mexico`s Gulf Coast and in the North East part of the country there are severe pollution problems on the electric distribution power systems insulators. To solve this problem, in specialized laboratories are reproduced the pollution conditions for their quantitative and qualitative analyses. In general terms, for this purpose special voltage transformers have been used that, for being imported, are very expensive; furthermore there is no defined selection criterion that allows the voltage source to supply the current recommended by the IEC (International Electrotechnical Commission). In this article, a proposal is presented to select a transformer that fulfills the IEC requirements. This equipment, because of its acquisition easiness and economy, permits that any teaching or research institution have a voltage source that allows the experimentation of the pollution phenomena at a minimum cost. [Espanol] En la costa del Golfo de Mexico y en el noroeste del pais hay severos problemas de contaminacion en los aisladores de los sistemas electricos de distribucion. Para solucionar este problema, se reproducen, en laboratorios especializados, las condiciones de contaminacion para su analisis cualitativo y cuantitativo. En general, con este proposito se han utilizado transformadores especiales de voltaje que por ser de importacion son muy costosos; ademas, no existe un criterio definido de seleccion que permita suministrar a la fuente de voltaje la corriente recomendada por el IEC (International Electrotechnical Commission). En este articulo se presenta una propuesta para seleccionar un transformador que cumpla con los requerimientos del IEC. Esta, por su facilidad de adquisicion y economia, permite que cualquier institucion docente o de investigacion cuente con una fuente de voltaje que permita la experimentacion de los fenomenos contaminantes con un costo minimo.

    Full Text Available During the assessments carried out by the authors at the diverse laboratories pertaining to the network of accredited laboratories - known as the Brazilian Calibration Network (RBC - the authors verified the difficulties that these laboratories had in meeting the requirements of NBR ISO/IEC 17025:2001 (Standard, related to the maintenance of documents in the electronic media. More and more laboratories are substituting traditional control with electronic document control, which allows for more agility in the recovery of information. These laboratories implement policies and procedures; however, they still feel insecure, in some way, as to how to meet all of these requirements, thereby giving rise to difficulties in the implementation of such. The aim of this paper is to discuss the control of documents stored in the electronic media, adopting requirement 4.3 of the Standard as the reference, and aiming, in this manner, to harmonize the assessment process of the procedures of document management in the electronic media, and to assist the laboratories in the interpretation of the Standard, so that they may implement systems that are adequate to their actual necessities and to their structural size, while at the same time complying with the referred to requirement. This work will not broach the treatment given to the records (requirement 4.12 of the Standard, facts (requirement 5.4.7 nor to the electronic transmission of results (requirement 5.10.7, leaving these subjects for posterior discussions.

    In order to investigate how cells recognize biomaterials, mRNA that was expressed in attached Intestinal epithelial cells (IEC-6) on various suture substrates was evaluated. The expressed cell cycle regulators (cyclin D1, CDK4 and p21) mRNA were then isolated and detected using the real time- polymerase chain reaction (PCR) method. As a result, cyclin D1 gene expression was affected by cell-polymer adhesion and was associated with cell proliferation. In addition, CDK4 gene expression was affected by cell proliferation rather than by cell-biomaterial interaction. The p21 mRNA gene expression was higher in cells on more hydrophilic surfaces than on hydrophobic surfaces. Further, the cyclin D1, CDK4 and p21 gene expression were also influenced by the surface chemistry of suture materials. We concluded that the expression of cyclin D1, CDK4 and p21 mRNA was a powerful method for studying cell-biomaterial interactions or the evaluation of the carcinogenic activity of biomaterials. - Highlights: ►We evaluated the effects of biomaterials on the cyclin D1, CDK4 and p21 expression. ►Cell-polymer adhesion and cell proliferation affected cyclin D1 and CDK4 expression. ►The p21 expression was higher on more hydrophilic surfaces than on hydrophobic. ►They were also influenced by surface chemistry of biomaterials.

    Equine Metabolic Syndrome (EMS) is a steadily growing life-threatening endocrine disorder linked to insulin resistance, oxidative stress, and systemic inflammation. Inflammatory microenvironment of adipose tissue constitutes the direct tissue milieu for various cell populations, including adipose-derived mesenchymal stromal cells (ASCs), widely considered as a potential therapeutic cell source in the course of the treatment of metabolic disorders. Moreover, elevated oxidative stress induces inflammation in intestinal epithelial cells (IECs)-the first-line cells exposed to dietary compounds. In the conducted research, we showed that in vitro application of Spirulina platensis contributes to the restoration of ASCs' and IECs' morphology and function through the reduction of cellular oxidative stress and inflammation. Enhanced viability, suppressed senescence, and improved proliferation of ASCs and IECs isolated from metabolic syndrome-affected individuals were evident following exposition to Spirulina. A protective effect of the investigated extract against mitochondrial dysfunction and degeneration was also observed. Moreover, our data demonstrate that Spirulina extract effectively suppressed LPS-induced inflammatory responses in macrophages. In vivo studies showed that horses fed with a diet based on Spirulina platensis supplementation lost weight and their insulin sensitivity improved. Thus, our results indicate the engagement of Spirulina platensis nourishing as an interesting alternative approach for supporting the conventional treatment of equine metabolic syndrome.

    2010-07-01

    The INCOSE Systems Engineering Handbook is the official INCOSE reference document for understanding systems engineering (SE) methods and conducting SE activities. Over the years, the Handbook has evolved to accommodate advances in the SE discipline and now serves as the basis for the Certified Systems Engineering Professional (CSEP) exam. Due to its evolution, the Handbook had become somewhat disjointed in its treatment and presentation of SE topics and was not aligned with the latest version of International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) 15288:2008, Systems and Software Engineering. As a result, numerous inconsistencies were identified that could confuse practitioners and directly impact the probability of success in passing the CSEP exam. Further, INCOSE leadership had previously submitted v3.1 of the Handbook to ISO/IEC for consideration as a Technical Report, but was told that the Handbook would have to be updated to conform with the terminology and structure of new ISO/IEC15288:2008, Systems and software engineering, prior to being considered. The revised INCOSE Systems Engineering Handbook v3.2 aligns with the structure and principles of ISO/IEC 15288:2008 and presents the generic SE life-cycle process steps in their entirety, without duplication or redundancy, in a single location within the text. As such, the revised Handbook v3.2 serves as a comprehensive instructional and reference manual for effectively understanding SE processes and conducting SE and better serves certification candidates preparing for the CSEP exam.

    TGF-beta and FAK modulate cell migration, differentiation, proliferation and apoptosis, and TGF-beta promotes FAK transcription in intestinal epithelial cells via Smad-dependent and independent pathways. We utilized a 1320 bp FAK promoter-luciferase construct to characterize basal and TGF-beta-mediated FAK gene transcription in IEC-6 cells. Inhibiting JNK or Akt negated TGF-beta-stimulated promoter activity; ERK inhibition did not block the TGF-beta effect but increased basal activity. Co-transfection with Co-Smad4 enhanced the TGF-beta response while the inhibitory Smad7 abolished it. Serial deletions sequentially removing the four Smad binding elements (SBE) in the 5' untranslated region of the promoter revealed that the two most distal SBE's are positive regulators while SBE3 exerts a negative influence. Mutational deletion of two upstream p53 sites enhanced basal but did not affect TGF-beta-stimulated increases in promoter activity. TGF-beta increased DNA binding of Smad4, phospho-Smad2/3 and Runx1/AML1a to the most distal 435 bp containing 3 SBE and 2 AML1a sites by ChIP assay. However, although point mutation of SBE1 ablated the TGF-beta-mediated rise in SV40-promoter activity, mutation of AML1a sites did not. TGF-beta regulation of FAK transcription reflects a complex interplay between positive and negative non-Smad signals and SBE's, the last independent of p53 or AML1a.

The regulations NFPA 70, NFPA 780 and IEC 62305 are studied for the analysis and design of the lightning rod. The standards are analyzed, according to the rules applied at specialized companies in the elaboration and installation of lightning rod, in order to determine if these are adequate and used in correctly shape . A report is made about the design of a lightning rod and preventive measures for areas with regular activity of atmospheric discharges. The different devices for the elaboration and installation of a lightning rod are investigated in order to later use and exploitation. The design for the implementation of a system of conventional lightning rod, type tips of Franklin, was realized at the Iglesia Catedral of Ciudad Quesada. The materials that were used in this type of lightning rod, have followed the regulation NFPA 780. Several approximate plans of the cathedral have been performed to appreciate good the design, both in 2D as in 3D; these allow a better panorama of the installation. The distance between devices has been fundamental to take into account in the design of a system of lightning rod, as it marks an important difference between the area to protect and areas that may be exposed to an atmospheric discharge. The rule NFPA 780 has been established that to design the location of the lightning captors can use the rolling sphere method, also has marked the requirements of the downspouts systems and grounding systems. Before locating a lightning protection system it is important to be informed of the principal characteristics of the area to be protected; as on several occasions, the particularities of the selected area have

    Transient voltage suppressor (TVS) diodes were fabricated using low-temperature epitaxy technology and were employed to improve the electrostatic discharge (ESD) strength of GaN light emitting diodes (LEDs). The ESD performance and the protection capability of the TVS diodes were investigated using various ESD simulators of the human body model (HBM), the IEC (International Electrotechnical Commission) 61000-4-2 (IEC), and a transmission line pulse (TLP) analysis. According to the IEC, the manufactured TVS diode could withstand in excess of ±30 kV without any degradation in the I-V characteristics; meanwhile, the GaN LED itself exhibited catastrophic degradation caused by weak ESD power. The GaN LED assembled with the TVS diode had improved ESD robustness from ±3.8 kV to ±8 kV according to the HBM, from ±1.2 kV to > ±30 kV according to the IEC, and from 4.3 A to > ±30 A according to the TLP analysis. Furthermore, its performance was maintained perfect I-V manner with negligible changes in radiant power, leakage current and breakdown voltage up to the limit of the ESD simulators. Namely, the manufactured TVS diodes were effective in the protection of sensitive GaN LEDs from very strong ESD shocks.

    Toronto-based WhalePower Corporation has developed turbine blades that are modeled after humpback whale flippers. The blades, which incorporate tubercles along the leading edge of the blade, have been fitted to a Wenvor 25 kW turbine installed in North Cape, Prince Edward Island at a test site for the Wind Energy Institute of Canada (WEICan). A test was conducted to characterize the power performance of the prototype wind turbine. This report described the wind turbine configuration with particular reference to turbine information, power rating, blade information, tower information, control systems and grid connections. The test site was also described along with test equipment and measurement procedures. Information regarding power output as a function of wind speed was included along with power curves, power coefficient and annual energy production. The results for the power curve and annual energy production contain a level of uncertainty. While measurements for this test were collected and analyzed in accordance with International Electrotechnical Commission (IEC) standards for performance measurements of electricity producing wind turbines (IEC 61400-12-1), the comparative performance data between the prototype WhalePower wind turbine blade and the Wenvor standard blade was not gathered to IEC data standards. Deviations from IEC-61400-12-1 procedures were listed. 6 tabs., 16 figs., 3 appendices.

    This news brief is about a video on adolescent reproductive health in developing countries, which was produced in preparation for the Beijing Fourth World Conference on Women. The video documents the adolescent experiences of a rural girl in Bangladesh, an urban girl in Mexico City, and a poor girl from rural Thailand. The photos and story explain the actual lives of these adolescent women and give voice to their thoughts about their lives. Moni, who is 13, lives in a remote rural village in Bangladesh. She began menstruating 6 months after her marriage. Her role is to do the housework for her husband's family of 12 people. There is no choice. Luz, who is 15 years of age and lives in Mexico City, experienced a nonmarital pregnancy and cessation of education. The unplanned pregnancy occurred due to lack of knowledge. The 19-year-old Nagor lived in a small Thai village until she became involved in prostitution through her sister and other village girls. The attraction was income to help her family. Lack of knowledge and being the youngest of 9 children contributed to her situation. The video uses these cases to illustrate the importance of empowerment of women through equal educational opportunity, access to reproductive health information and services, and economic independence. The cases illustrate dramatically how the lack of information can impact strongly on women's lives. The video is available with English narration. JOICFP has a variety of audio-visual materials on reproductive health education, family planning, and empowerment of women.

    The Calibration Advisory Panel (CAP) is composed of calibration experts from each of the Earth Observing System (EOS) instruments, science investigation, and cross-calibration teams. These members come from a variety of institutions and backgrounds. In order to facilitate an exchange of ideas, and assure a common basis for communication, it was desirable to assemble this list of definitions. These definitions were developed for use by the visible and near-infrared working group, and the thermal infrared working group. Where necessary or appropriate, deviations from these for specific instruments or other sensor types are given in the individual calibration plans. The definitions contained in this document are derived, wherever possible, from definitions accepted by international and national metrological commissions including the United States National Institute of Standards and Technology (NIST), the International Bureau of Weights and Measures (BIPM), the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO), and the International Organization of Legal Metrology (OIML).

    The frequency convertor and the automatic control system, which can be used in the multi-drive electromechanical system with a few induction motions, are considered. The paper presents the structure of existing modern multi-drive electric drives inverters, namely, electric drives with a total frequency converter and few electric motions, and an electric drive, in which the converter is used for power supply and control of the independent frequency. It was shown that such technical solutions of frequency converters possess a number of drawbacks. The drawbacks are given. It was shown that the control of technological processes using the electric drive of this structure may be provided under very limited conditions, as the energy efficiency and the level of electromagnetic compatibility of electric drives is low. The authors proposed using a multi-inverter structure with an active rectifier in multidrive electric drives with induction motors frequency converters. The application of such frequency converter may solve the problem of electromagnetic compatibility, namely, consumption of sinusoidal currents from the network and the maintenance of a sinusoidal voltage and energy compatibility, namely, consumption of practically active energy from the network. Also, the paper proposes the use of the automatic control system, which by means of a multi-inverter frequency converter provides separate control of drive machines and flexible regulation of technological processes. The authors present oscillograms, which confirm the described characteristics of the developed electrical drive. The possible subsequent ways to improve the multi-motor drives are also described.

    Two ELISAs to quantify antibodies to BoHV-1 in the sera of cattle and immunized guinea pigs were developed and validated using ISO/IEC 17025 standards. The cut-off value of the assay was established at 20% positivity of a high positive control for screening of cattle. Using this threshold, the assay properly classified the OIE bovine reference sera EU1, EU2 and EU3. For vaccine potency testing, a cut-off of 40% was selected for both species. The reliability of the assays, given by their diagnostic sensitivity and specificity, using the threshold of 40% was 89.7% and 100%, respectively, for bovines and 94.9% and 100% for guinea pigs, respectively. There was almost perfect agreement between the ELISA and virus neutralization results. In addition, after vaccination, there was a good correlation between the neutralizing and ELISA antibody titers of the serum from the same bovine or guinea pig, sampled at 60 and 30 days post-vaccination, respectively (R(bovine)=0.88, R(guinea pig)=0.92; p<0.0001). A similar correlation was observed when analyzing the mean antibody titers of groups of vaccinated animals (R(bovine)=0.95 and R(guinea pig)=0.97; p<0.0001), indicating the relevance of the ELISAs for batch to batch vaccine potency testing in the target species and in the laboratory animal model. The intermediate precision of the assays expressed as the relative coefficient of variation (CV) of the positive control assayed over a 3-year period in the same laboratory was 22.2% for bovines and 23.1% for guinea pigs. The reproducibility of both techniques obtained in inter-laboratory assays was CV=12.4% for bovines and CV approximately 0 for guinea pigs, which met the requirements of the OIE (CV<30%). The validated ELISAs represent important methods for vaccine potency testing and for controlling BoHV-1 infections. Copyright (c) 2010 Elsevier B.V. All rights reserved.

  16. How ISO/IEC 17799 can be used for base lining information assurance among entities using data mining for defense, homeland security, commercial, and other civilian/commercial domains

    One goal of database mining is to draw unique and valid perspectives from multiple data sources. Insights that are fashioned from closely-held data stores are likely to possess a high degree of reliability. The degree of information assurance comes into question, however, when external databases are accessed, combined and analyzed to form new perspectives. ISO/IEC 17799, Information technology-Security techniques-Code of practice for information security management, can be used to establish a higher level of information assurance among disparate entities using data mining in the defense, homeland security, commercial and other civilian/commercial domains. Organizations that meet ISO/IEC information security standards have identified and assessed risks, threats and vulnerabilities and have taken significant proactive steps to meet their unique security requirements. The ISO standards address twelve domains: risk assessment and treatment, security policy, organization of information security, asset management, human resources security, physical and environmental security, communications and operations management, access control, information systems acquisition, development and maintenance, information security incident management and business continuity management and compliance. Analysts can be relatively confident that if organizations are ISO 17799 compliant, a high degree of information assurance is likely to be a characteristic of the data sets being used. The reverse may be true. Extracting, fusing and drawing conclusions based upon databases with a low degree of information assurance may be wrought with all of the hazards that come from knowingly using bad data to make decisions. Using ISO/IEC 17799 as a baseline for information assurance can help mitigate these risks.

    In fiscal years (FY) 2016 and 2017, with support from the U.S. Department of Homeland Security (DHS), Brookhaven National Laboratory (BNL) examined the International Atomic Energy Agency (IAEA) radiological emergency response and preparedness products (guidance and tools) to determine which of these products could be useful to U.S. first responders. The IAEA Incident and Emergency Centre (IEC), which is responsible for emergency preparedness and response, offers a range of tools and guidance documents for responders in recognizing, responding to, and recovering from radiation emergencies and incidents. In order to implement this project, BNL obtained all potentially relevant tools and products produced by the IAEA IEC and analyzed these materials to determine their relevance to first responders in the U.S. Subsequently, BNL organized and hosted a workshop at DHS National Urban Security Technology Laboratory (NUSTL) for U.S. first responders to examine and evaluate IAEA products to consider their applicability to the United States. This report documents and describes the First Responder Product Evaluation Workshop, and provides recommendations on potential steps the U.S. federal government could take to make IAEA guidance and tools useful to U.S. responders.

    The project was planned for a duration of 4 years. Afterwards it has been extended over 6 years and finally stopped after 3 1/2 years. Therefore, of course results of field tests with an internally cooled 400 kV cable are not available. Nevertheless, this conductor cooled high power cable has been developed to such an extend, that this manufactured cable could withstand type tests according to IEC/VDE recommendations. Even by missing field tests it is obvious that a high power cable for 400 kV is available.

    Tumor necrosis factor-alpha (TNF-α) plays an important role in the developing process of inflammatory bowel disease. Tight junction protein zonula occludens-1 (ZO-1), one of epithelial junctional proteins, maintains the permeability of intestinal barrier. The objective of this study was to investigate the mechanism of the protective effect of baicalin on TNF-α-induced injury and ZO-1 expression in intestinal epithelial cells (IECs). We found that baicalin pretreatment significantly improved cell viability and cell migration following TNF-α stimulation. miR-191a inhibitor increased the protective effect of baicalin on cell motility injured by TNF-α. In addition, miR-191a down-regulated the mRNA and protein level of its target gene ZO-1. TNF-α stimulation increased miR-191a expression, leading to the decline of ZO-1 mRNA and protein. Moreover, pretreatment with baicalin reversed TNF-α induced decrease of ZO-1 and increase of miR-191a, miR-191a inhibitor significantly enhanced ZO-1 protein expression restored by baicalin. These results indicate that baicalin exerts a protective effect on IEC-6 (rat small intestinal epithelial cells) cells against TNF-α-induced injury, which is at least partly via inhibiting the expression of miR-191a, thus increasing ZO-1 mRNA and protein levels.

    A quality system for the diagnosis of exotic animal diseases was developed at the national centre for animal and plant health (CENSA), responsible for coordinating the clinical, epizootiological and laboratory diagnosis of causal agents of exotic animal diseases in Cuba. A model was designed on the basis of standard ISO 9001:2000 of the International Organization for Standardization (ISO), standard ISO/IEC 17025:1999 of ISO and the International Electrotechnical Commission, recommendations of the World Organisation for Animal Health (OIE) and other regulatory documents from international and national organisations that deal specifically with the treatment of emerging diseases. Twenty-nine standardised operating procedures were developed, plus 13 registers and a checklist to facilitate the evaluation of the system. The effectiveness of the quality system was confirmed in the differential diagnosis of classical swine fever at an animal virology laboratory in Cuba.

    2014-01-01

    Digital radiography (DR) technologies have the advantage of a wide dynamic range compared to their film-screen predecessors, however, this poses a potential for increased patient exposure if left unchecked. Manufacturers have developed the exposure index (EI) to counter this, which provides radiographers with feedback on the exposure reaching the detector. As these EIs were manufacturer-specific, a wide variety of EIs existed. To offset this, the international standardised EI has been developed by the International Electrotechnical Commission (IEC) and the American Association of Physicists in Medicine (AAPM). The purpose of this article is to explore the current literature relating to EIs, beginning with the historical development of the EI, the development of the standardised EI and an exploration of common themes and studies as evidenced in the research literature. It is anticipated that this review will provide radiographers with a useful guide to understanding EIs, their application in clinical practice, limitations and suggestions for further research

    1983-01-01

    The use of lasers has increased greatly over the past 15 years or so, to the extent that they are now used routinely in many occupational and public situations. There has been an increasing awareness of the potential hazards presented by lasers and substantial efforts have been made to formulate safety standards. In the UK the relevant Safety Standard is the British Standards Institution Standard BS 4803. This Standard was originally published in 1972 and a revision has recently been published (BS 4803: 1983). The revised standard has been developed using the American National Standards Institute Standard, ANSI Z136.1 (1973 onwards), as a model. In other countries, national standards have been similarly formulated, resulting in a large measure of international agreement through participation in the work of the International Electrotechnical Commission (IEC). The bases of laser safety standards are biophysical data on threshold injury effects, particularly on the retina, and the development of theoretical mode...

    Purpose The purpose of this paper is to describe a study which aimed to develop and validate an assessment method for the International Electrotechnical Commission (IEC) 80001-1 (IEC, 2010) standard (the Standard); raise awareness; improve medical IT-network project risk management processes; and improve intensive care unit patient safety. Design/methodology/approach An assessment method was developed and piloted. A healthcare IT-network project assessment was undertaken using a semi-structured group interview with risk management stakeholders. Participants provided feedback via a questionnaire. Descriptive statistics and thematic analysis was undertaken. Findings The assessment method was validated as fit for purpose. Participants agreed (63 per cent, n=7) that assessment questions were clear and easy to understand, and participants agreed (82 per cent, n=9) that the assessment method was appropriate. Participant's knowledge of the Standard increased and non-compliance was identified. Medical IT-network project strengths, weaknesses, opportunities and threats in the risk management processes were identified. Practical implications The study raised awareness of the Standard and enhanced risk management processes that led to improved patient safety. Study participants confirmed they would use the assessment method in future projects. Originality/value Findings add to knowledge relating to IEC 80001-1 implementation.

    Currently daily quality control (QC) tests for mammography systems are generally evaluated by using visual analysis phantoms, which of course means subjective measurement. In our study, however, we evaluated a novel digital phantom, the 1Shot Phantom M plus (1Shot Phantom), together with automatic analysis software dedicated for mammography systems using Fuji computed radiography (FCR). The digital phantom enables objective evaluation by providing for actual physical measurement rather than subjective visual assessment. We measured contrast to noise ratio (CNR), image receptor homogeneity, missed tissue at chest wall side, modulation transfer function (MTF), and geometric distortion utilizing the 1Shot Phantom. We then compared the values obtained using the 1Shot Phantom with values obtained from the European guidelines and International Electrotechnical Commission (IEC) standards. In addition, we evaluated the convenience of using the digital phantom. The values utilizing the 1Shot Phantom and those from the European guidelines and IEC standards were consistent, but the QC tests for the European guidelines and IEC standards methods took about six hours while the same QC tests using the 1Shot Phantom took 10 minutes or less including exposure of the phantom image, measurement, and analysis. In conclusion, the digital phantom and dedicated software proved very useful and produced improved analysis for mammography systems using FCR in clinical daily QC testing because of their objectivity and substantial time-saving convenience.

    When multi-wire proportional counters are used for monitoring of mixed contamination of α and β radioactivity, both of the signals should be distinguished as far as possible from requirement of radiation protection. The rules provided by the recommendation standard of International Electrotechnical Committee (IEC) and the national standard of China indicate: For fixed personal surface contamination monitoring assembly, the response of the α-counting channel to β events should be smaller than 1% of response of the α-counting channel to α events, and the response of β-counting channel to β events should be smaller than that of the response of α-counting channel to the same events. To distinguish one kind of signal from another, amplitude discrimination method is used usually. (3 figs)

    According to the new standards on the high-altitude electromagnetic pulse (HEMP) developed by International Electrotechnical Commission (IEC), the target parameter requirements of the key structure of the hybrid HEMP simulator are decomposed. Firstly, the influences of the different excitation sources and biconical structures to the key parameters of the radiated electric field wave shape are investigated and analyzed. Then based on the influence curves the target parameter requirements of the pulse generator are proposed. Finally the appropriate parameters of the biconical structure and the excitation sources are chosen, and the computational result of the electric field in free space is presented. The results are of great value for the design of the hybrid HEMP simulator. (authors)

    Full Text Available Measurement and diagnostic systems based on electronic sensors have been increasingly essential in the standardization of hospital equipment. The technical standard IEC (International Electrotechnical Commission 60601-2-19 establishes requirements for neonatal incubators and specifies the calibration procedure and validation tests for such devices using sensors systems. This paper proposes a new procedure based on an inferential neural network to evaluate and calibrate a neonatal incubator. The proposal presents significant advantages over the standard calibration process, i.e., the number of sensors is drastically reduced, and it runs with the incubator under operation. Since the sensors used in the new calibration process are already installed in the commercial incubator, no additional hardware is necessary; and the calibration necessity can be diagnosed in real time without the presence of technical professionals in the neonatal intensive care unit (NICU. Experimental tests involving the aforementioned calibration system are carried out in a commercial incubator in order to validate the proposal.

    A wave model test bed is established to benchmark, test and evaluate spectral wave models and modeling methodologies (i.e., best practices) for predicting the wave energy resource parameters recommended by the International Electrotechnical Commission, IEC TS 62600-101Ed. 1.0 ©2015. Among other benefits, the model test bed can be used to investigate the suitability of different models, specifically what source terms should be included in spectral wave models under different wave climate conditions and for different classes of resource assessment. The overarching goal is to use these investigations to provide industry guidance for model selection and modeling best practices depending on the wave site conditions and desired class of resource assessment. Modeling best practices are reviewed, and limitations and knowledge gaps in predicting wave energy resource parameters are identified.

    Feola, Luigi; Langella, Roberto; Testa, Alfredo

    2015-12-01

    In this paper, a new analytical estimator for light flicker in frequency domain, which is able to take into account also the frequency components neglected by the classical methods proposed in literature, is proposed. The analytical solutions proposed apply for any generic stationary signal affected by interharmonic distortion. The light flicker analytical estimator proposed is applied to numerous numerical case studies with the goal of showing i) the correctness and the improvements of the analytical approach proposed with respect to the other methods proposed in literature and ii) the accuracy of the results compared to those obtained by means of the classical International Electrotechnical Commission (IEC) flickermeter. The usefulness of the proposed analytical approach is that it can be included in signal processing tools for interharmonic penetration studies for the integration of renewable energy sources in future smart grids.

  5. Some advanced parametric methods for assessing waveform distortion in a smart grid with renewable generation

    Alfieri, Luisa

    2015-12-01

    Power quality (PQ) disturbances are becoming an important issue in smart grids (SGs) due to the significant economic consequences that they can generate on sensible loads. However, SGs include several distributed energy resources (DERs) that can be interconnected to the grid with static converters, which lead to a reduction of the PQ levels. Among DERs, wind turbines and photovoltaic systems are expected to be used extensively due to the forecasted reduction in investment costs and other economic incentives. These systems can introduce significant time-varying voltage and current waveform distortions that require advanced spectral analysis methods to be used. This paper provides an application of advanced parametric methods for assessing waveform distortions in SGs with dispersed generation. In particular, the Standard International Electrotechnical Committee (IEC) method, some parametric methods (such as Prony and Estimation of Signal Parameters by Rotational Invariance Technique (ESPRIT)), and some hybrid methods are critically compared on the basis of their accuracy and the computational effort required.

    2013-07-01

    With the push towards siting wind turbines farther offshore due to higher wind quality and less visibility, floating offshore wind turbines, which can be located in deep water, are becoming an economically attractive option. The International Electrotechnical Commission's (IEC) 61400-3 design standard covers fixed-bottom offshore wind turbines, but there are a number of new research questions that need to be answered to modify these standards so that they are applicable to floating wind turbines. One issue is the appropriate simulation length needed for floating turbines. This paper will discuss the results from a study assessing the impact of simulation length on the ultimate and fatigue loads of the structure, and will address uncertainties associated with changing the simulation length for the analyzed floating platform. Recommendations of required simulation length based on load uncertainty will be made and compared to current simulation length requirements.

    The quality standard "UNE-EN-ISO 17043: 2010. Conformity assessment. General requirements for proficiency testing" applies to centers that organize intercomparisons in all areas. In the case of clinical microbiology laboratories, these intercomparisons must meet the management and technical standards required to achieve maximum quality in the performance of microbiological analysis and the preparation of test items (sample, product, data or other information used in the proficiency test) to enable them to be accredited. Once accredited, these laboratories can operate as a tool for quality control laboratories and competency assessment. In Spain, accreditation is granted by the Spanish Accreditation Body [Entidad Nacional de Acreditación (ENAC)]. The objective of this review is to explain how to apply the requirements of the standard to laboratories providing intercomparisons in the field of clinical microbiology (the organization responsible for all the tasks related to the development and operation of a proficiency testing program). This requires defining the scope and specifying the technical requirements (personnel management, control of equipment, facilities and environment, the design of the proficiency testing and data analysis for performance evaluation, communication with participants and confidentiality) and management requirements (document control, purchasing control, monitoring of complaints / claims, non-compliance, internal audits and management reviews).

    Medical professionals' attitude towards homosexuals affects health care offered to such patients with a different sexual orientation. There is absence of literature that explores the attitudes of Indian medical students or physicians towards homosexuality. This study aimed to evaluate Indian medical students and interns' knowledge about homosexuality and attitude towards homosexuals. After IEC approval and written informed consent, a cross-sectional study was conducted on a purposive sample of undergraduate medical students and interns studying in one Indian medical college. The response rate was 80.5%. Only completely and validly filled responses (N = 244) were analyzed. The participants filled the Sex Education and Knowledge about Homosexuality Questionnaire (SEKHQ) and the Attitudes towards Homosexuals Questionnaire (AHQ). SEKHQ consisted of 32 statements with response chosen from 'true', 'false', or 'don't know'. AHQ consisted of 20 statements scorable on a 5-point Likert scale. Multiple linear regression was used to find the predictors of knowledge and attitude. Medical students and interns had inadequate knowledge about homosexuality, although they endorsed a neutral stance insofar as their attitude towards homosexuals is concerned. Females had more positive attitudes towards homosexuals. Knowledge emerged as the most significant predictor of attitude; those having higher knowledge had more positive attitudes. Enhancing knowledge of medical students by incorporation of homosexuality related health issues in the curriculum could help reduce prejudice towards the sexual minority and thus impact their future clinical practice.

  1. Determination of internal series resistance of PV devices: repeatability and uncertainty

    Trentadue, Germana; Pavanello, Diego; Salis, Elena; Field, Mike; Müllejans, Harald

    2016-01-01

    The calibration of photovoltaic devices requires the measurement of their current–voltage characteristics at standard test conditions (STC). As the latter can only be reached approximately, a curve translation is necessary, requiring among others the internal series resistance of the photovoltaic device as an input parameter. Therefore accurate and reliable determination of the series resistance is important in measurement and test laboratories. This work follows standard IEC 60891 ed 2 (2009) for the determination of the internal series resistance and investigates repeatability and uncertainty of the result in three aspects for a number of typical photovoltaic technologies. Firstly the effect of varying device temperature on the determined series resistance is determined experimentally and compared to a theoretical derivation showing agreement. It is found that the series resistance can be determined with an uncertainty of better than 5% if the device temperature is stable within  ±0.1 °C, whereas the temperature range of  ±2 °C allowed by the standard leads to much larger variations. Secondly the repeatability of the series resistance determination with respect to noise in current–voltage measurement is examined yielding typical values of  ±5%. Thirdly the determination of the series resistance using three different experimental set-ups (solar simulators) shows agreement on the level of  ±5% for crystalline Silicon photovoltaic devices and deviations up to 15% for thin-film devices. It is concluded that the internal series resistance of photovoltaic devices could be determined with an uncertainty of better than 10%. The influence of this uncertainty in series resistance on the electrical performance parameters of photovoltaic devices was estimated and showed a contribution of 0.05% for open-circuit voltage and 0.1% for maximum power. Furthermore it is concluded that the range of device temperatures allowed during determination of series

    Full Text Available Analysis and studying of the terrorism in all its facets is a complex entangled problem with less clear legal regulation that it might seem at first glance, especially after its transformation from local phenomenon into a world threat. Hitherto terrorism and actions connected to it have been criminalized by the majority of states. There are in modern criminal law whole systems of rules on criminal liability for terrorism which differs considerably from country to country. Terrorism has been criminalized in numerous international regional and universal antiterrorist legal instruments. The author notes that differences in definitions that are enshrined in them hinders international cooperation in criminal matters with respect to terrorist cases. Difficulties reside in the necessity to meet the dual criminality requirement and in the political offense exception. These difficulties can only be overcome through elaboration of a universally recognized definition of the notion of international terrorism and making it legally binding via its inclusion into a universal convention. The issue of definition of international terrorism is an important part of an efficient mutual assistance among states in fight against this crime. In this article the author accounts of actual ways of tackling by the international community of the issue of criminalization of international terrorism and of factors influencing them.

    Due to the concentration of electricity production in large power plants, the need of higher power transmissions, and the protection of environment, developement of a 400 kV water cooled cable in the power range of 1 to 5 GVA was undertaken. The fabrication and testing of equipment, engineering of cable components, fabrication of a test cable, development of cable terminal laboratory, testing of test cable, field testing of test cable, fabrication of industrial cable laboratory, testing of industrial cable, field testing of industrial cable, and system analysis for optimization were prepared. The field testing was impossible to realize. However, it is proved that a cable consisting of an internal stainless steel water cooled tube, covered by stranded copper profiles, insulated with heavy high quality paper, and protected by an aluminum cover can be produced, withstand tests accordingly to IEC/VDE recommendations, and is able to fulfill all exploitation conditions.

    A number of international bodies have attempted to stimulate wider interest in Quality Assurance in X-ray departments. A major initiative has been taken by WHO with the publication of its recommendations in 1982 under the title Quality Assurance in Diagnostic Radiology, in which they indicated the action that should be taken at various national, professional and local levels. The recommendations of ICRP in Publication 26 point to the need for quality assurance programmes that will obtain optimum diagnostic information at minimum cost and minimum patient dose. ICRU have been considering the need for cost-effective quality assurance programmes and the specification of standards for image quality. The IEC and various manufacturers' organisations have begun to consider the part they can play in setting up quality control procedures. The most active group has been the ISRRT, which has arranged a series of seminars and workshops for radiographers in various parts of the world. Future needs for international support lie in the provision of training programmes, the publication of comparative statistical data and the development of image quality standards. (author)

    When procuring new equipment, performance and safety should be specified, if possible by reference to international standards. Some of the characteristics of the International Electrotechnical Commission (IEC) standard for X-ray generators, in particular the accuracy of the operating data, are described. The quality control tests to be performed after installation comprise acceptance test, status test and constancy test. The first two involve absolute measurements and will be the responsibility of physicists or engineers. Apparently limiting values stipulated by users are a factor of two lower than the limits of the IEC standard. By means of an example it is shown that modern X-ray generators can meet the lower limits of the users without problems. In order to obtain optimum initial quality when procuring new equipment operating data, limiting values must be specified and must be verified by acceptance testing, etc. However, in many countries physicists and engineers are not available for this job. A relatively uncomplicated test object can be used by radiographers for checks on fluoroscopic systems. The findings from such tests in Denmark are compared with other published findings and good agreement is found. Therefore it is proposed that such uncomplicated tests could form the basis for quality evaluation. (author)

    The National Renewable Energy Laboratory (NREL) is developing tests and procedures that will determine if the configuration of a small photovoltaic (PV) system is suitable for its intended use, and if the system will perform as specified. An overview of these procedures is presented in this paper. Development of standard test procedures will allow designers, manufacturers, system integrators, users, and independent laboratories to assess the performance of PV systems under outdoor prevailing conditions. An NREL Technical Report detailing the procedures is under way, and the IEEE Standards Coordinating Committee 21 (SCC21) has established a project on this subject. The work will be submitted to the IEEE SCC21 and International Electrotechnical Commission Technical Committee 82 (IEC TC82) for consideration as a consensus standard. Certification bodies such as PowerMark and PV Global Approval Program (PVGAP) may adopt the IEC and IEEE documents when testing systems. Developing standardized test methods and procedures at NREL to evaluate the outdoor performance of PV systems will encourage product quality and promote PV standards development. Standardized tests will assure people that PV systems will perform as specified for their intended applications. As confidence in PV systems increases, the successful commercialization of PV will grow internationally.

    It looks doubtless that the need for an international cooperation to solve the worldwide energy problems is already a concern of individuals, institutions, and governments. This is an improvement. But there is something lacking. The author refers to the Atoms for Peace speech, the origin of the IAEA and of the subsequent spreading of the nuclear option. He also refers back to the call made by the Mexican government for a worldwide energy cooperation. He stresses the need for governments to cooperate, so that this international cooperation on energy can be put into operation for the benefit of mankind

    Pencil ionization chambers are used for beam dosimetry in computed tomography equipment (CT). In this study, a new calibration methodology was established, in order to make the Calibration Laboratory of Instituto de Pesquisas Energeticas e Nucleares (LCI) suitable to international metrological standards, dealing with specific procedures for calibration of these chambers used in CT. Firstly, the setup for the new RQT radiation qualities was mounted, in agreement with IEC61267 from the International Electrotechnical Commission (IEC). After the establishment of these radiation qualities, a specific calibration methodology for pencil ionization chambers was set, according to Technical Report Series No. 457, from the International Atomic Energy Agency (IAEA), which describes particularities of the procedure to be followed by the Secondary Standard Dosimetry Laboratories (SSDL's), concerning to collimation and positioning related to the radiation beam. Initially, PPV (kV) measurements and the determination of copper additional filtrations were carried out, measuring the half value layers (HVL) recommended by the IEC 61267 standard, after that the RQT 8, RQT 9 and RQT 10 radiation quality references were established. For additional filters, aluminum and copper of high purity (around 99.9%) were used. RQT's in thickness of copper filters equivalent to the set 'RQR (Al) + Additional Filtration (Cu)' was directly found by an alternative methodology used to determine additional filtrations, which is a good option when RQR's have not the possibility of be setting up. With the establishment of this new methodology for the ionization pencil chambers calibration, the LCI is ready to calibrate these instruments according to the most recent international standards. Therefore, an improvement in calibration traceability, as well as in metrological services offered by IPEN to all Brazil is achieved. (author)

    1976-01-01

    Since the start of the post-war era, international safeguards were considered essential to ensure that nuclear materials should not be diverted to unauthorised uses. In parallel, it was proposed to set up an international atomic energy agency within the United Nations through which international cooperation in nuclear matters would be channelled and controlled. Created in 1957, the IAEA was authorized to administer safeguards in connection with any assistance it provided as well as at the request of Member State and of any party to bilateral or multilateral arrangements in its ambit. Today, there are two international treaties requiring that its parties should accept Agency safeguards unilaterally, the Latin America Tlatelolco Treaty of 1967, and the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), operative since 1970, which requires in particular that non-nuclear weapon states should accept Agency safeguards on its peaceful nuclear activities. Thus while NPT covers peaceful nuclear activities indiscriminately in a country, the Agency's original safeguards system is applied according to specific agreements and to given facilities. A basic conflict has now emerged between commercial interests and the increasing wish that transfer of nuclear equipment and know-how should not result in proliferation of military nuclear capacity; however, serious efforts are currently in progress to ensure universal application of IAEA safeguards and to develop them in step with the uses of nuclear energy.

    In recent years, Brazilian Nuclear Programme has been reviewed and updated by government authorities in face of the demand for energy supply and its associated environmental constraints. The immediate impact of new national programmes and projects in nuclear field is the increase in the number of exposed personnel and the consequent need for reliable dosimetry services in the country. Several Technical Documents related to internal dosimetry have been released by the International Atomic Energy Agency and International Commission on Radiological Protection. However, standard bioassay procedures and methodologies for bioassay data interpretation are still under discussion and, in some cases, both in routine and emergency internal monitoring, procedures can vary from one laboratory to another and responses may differ markedly among Dosimetry Laboratories. Thus, it may be difficult to interpret and use bioassay data generated from different laboratories of a network. The main goal of this work is to implement a National Network of Laboratories aimed to provide reliable internal monitoring services in Brazil. The establishment of harmonised in vivo and in vitro radioanalytical techniques, dose assessment methods and the implementation of the ISO/IEC 17025 requirements will result in the recognition of technical competence of the network.

    The International Electrotechnical Commission, IEC provided in its standard IEC 60601-1-3 (1994) to prevent the use during radioscopic irradiation of focal spot to skin distances less than 20 cm if the X-RAY EQUIPMENT is specified for RADIOSCOPY during surgery or 30 cm for other specified applications. This standard was reflected in the Japanese Industrial Standard JIS Z 4701-1997, which provided the minimum distance from focal spot to skin to be 30 cm for the use of a fluoroscopic and radiographic table (Under-table type). However, JIS had formerly provided the minimum distance to be 40 cm and so does the current Medical Treatment Law. The draft revision for the Medical Treatment Law currently discussed has consideration to adopt the value 30 cm in accordance with the current JIS. Our research intended to investigate the impact on the entrance surface dose for the change of the focal spot to skin distance from 40 cm to 30 cm. The result was 20-30% increase of the entrance surface dose for the focal spot to skin distance 30 cm. Taking patient exposure dose into account, we need further and more sufficient discussion with this result before adopting this value to the Medical Treatment Law. (author)

    The International Electrotechnical Commission (IEC) has stipulated that medical X-ray equipment for interventional procedures must display radiation doses such as air kerma in free air at the interventional reference point and dose area product to establish radiation safety for patients (IEC 60601-2-43). However, it is necessary to estimate entrance skin dose for the patient from air kerma for an accurate risk assessment of radiation skin injury. To estimate entrance skin dose from displayed air kerma in free air at the interventional reference point, it is necessary to consider effective energy, the ratio of the mass-energy absorption coefficient for skin and air, and the backscatter factor. In addition, since automatic exposure control is installed in medical X-ray equipment with flat panel detectors, it is necessary to know the characteristics of control to estimate exposure dose. In order to calculate entrance skin dose under various conditions, we investigated clinical parameters such as tube voltage, tube current, pulse width, additional filter, and focal spot size, as functions of patient body size. We also measured the effective energy of X-ray exposure for the patient as a function of clinical parameter settings. We found that the conversion factor from air kerma in free air to entrance skin dose is about 1.4 for protection. (author)

    In Working Group 3 of Sub-committee 62C of the international electrotechnical commission (IEC) a new project is underway [1] with the objective of specifying requirements for the performance characteristics of instruments for the non-invasive measurement of the X-ray tube voltage in diagnostic radiology. In this draft the X-ray tube voltage is specified in terms of the practical peak voltage [2]. The objective of the present work is to perform a tentative type test, based on the ''Requirements for Instruments for Non-invasive Measurements of the X-ray Tube Voltage'' defined in the IEC draft, with a commercially available non-invasive high-voltage meter. The instrument was modified so that the practical peak voltage can be measured. It is shown that the instrument, with the modifications made, is suitable for the non-invasive measurement of the practical peak voltage between 50 kV and 150 kV within the required limits of variation of the response.

    The importance of radiation dose display of medical X-ray equipment was emphasized, while third edition of IEC(International Electrotechnical Commission) 60601 started to apply. The existing medical X-ray equipment selected a method for attaching the DAP(Dose Area Product) meter when the dose display. However, because the DAP meter was dependent on all of the income, And it did not yet produced in Korea. So, we received the support of Seoul R and BD Program(Grants No. C1152055) to produce DAP meter prototype of the Domestically technology. In this study, the performance of this prototype was evaluated by comparing the German company's product. Evaluation item was an electronic capture performance, radiation dose dependence, radiation quality dependence, energy transmittance, repeatability, light transmittance of 6 entries. And IEC 60580 was based on this evaluation. Evaluation results were electronic capture performance intrinsic error 9.5%, radiation dose dependence limits of variation 1%, repeatabilit y coefficient of variation 2%, energy transmittance 91% each assessment was passed. However radiation quality dependence limits of variation 29%, light transmittance 55% was less than acceptance criteria

    As part of an ongoing effort to improve the modeling and prediction of small wind turbine dynamics, the National Renewable Energy Laboratory (NREL) tested a small horizontal-axis wind turbine in the field at the National Wind Technology Center. The test turbine was a 2.1-kW downwind machine mounted on an 18-m multi-section fiberglass composite tower. The tower was instrumented and monitored for approximately 6 months. The collected data were analyzed to assess the turbine and tower loads and further validate the simplified loads equations from the International Electrotechnical Commission (IEC) 61400-2 design standards. Field-measured loads were also compared to the output of an aeroelastic model of the turbine. In particular, we compared fatigue loads as measured in the field, predicted by the aeroelastic model, and calculated using the simplified design equations. Ultimate loads at the tower base were assessed using both the simplified design equations and the aeroelastic model output. The simplified design equations in IEC 61400-2 do not accurately model fatigue loads and a discussion about the simplified design equations is discussed.

    The need for faster PV qualification tests that more accurately match field observations is leading to tests with higher acceleration levels, and validating the new tests through comparison to field data is an important step. We have tested and compared a wide panel of backsheets according to a proposed new backsheet UV exposure qualification standard from the International Electrotechnical Commission (IEC). Weathering Technical Standard IEC 62788-7-2 specifies higher irradiance and higher black panel temperature UV Xenon exposures. We tested PVF, PVDF, PET, PA and FEVEbased backsheets in glass laminates and simple backsheet coupons in UV exposure condition A3 (0.8W/sqmnm@340nm and 90° C BPT) We find mild yellowing with no mechanical loss in the original lower intensity ASTM G155 0.55 W/sqm-nm 70C BPT exposure condition. The new A3 exposures creates mechanical loss in sensitive backsheets, with no effect on known durable backsheets. Results from the new exposure are closer to field mechanical loss data.

    The IAEA has now 200 Inspectors or so, and Euratom a similar number. People in Vienna are talking about increases of this staff, in the range of a possible doubling in the five years to come, although even an immediate restart of the expansion of nuclear industry, would not materialize significantly within this period. This means that keeping the same safeguarding approach would probably lead to another doubling of such staff in the ten following years, which is completely unrealistic. Such a staff is our of proportion with those of national inspectorates in other fields. The paper analyzes the basic irrealistic dogma which have hindered the progress of international safeguards, and recall the suggestions made since ten years to improve them

    Full text: This short presentation will indicate the general radiation protection background to protective measures against foodstuffs contaminated with radioactive substances. A number of international organizations are involved in various aspects of radiation protection, for example, the International Atomic Energy Agency (IAEA), the United Nations Food and Agriculture Organization (FAO), the United Nations Environment Programme (UNEP), and the World Health Organization (WHO). Two international organizations, however, provide the basic background. These are the International Commission on Radiological Protection (ICRP) and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). UNSCEAR provides the scientific information on radiation levels and effects. It consists of 21 member countries, with truly international coverage. It issues reports to the UN General Assembly, including comprehensive scientific annexes. Its latest comprehensive report was issued in 1982, the next is expected to be published in 1988. That report will include an assessment of the radiological consequences of the Chernobyl accident. The ICRP is a non-governmental organization. It has issued recommendations on radiation protection since 1928. The postulated biological basis for radiation protection recommendations involves two types of biological effects. The so-called non-stochastic effects, mainly due to cell death, appear only when the radiation doses exceed a certain threshold value. These effects, therefore, can only appear after high accidental exposures. After the Chernobyl accident, they only affected about 200 individuals involved in fire extinction and rescue work at the damaged nuclear power plant. Stochastic effects, with some simplification, may be seen as the result of initial changes in the genetic code of some surviving cells. If these cells are germ cells, this may lead to hereditary harm. If they are somatic cells, the result could be cancer

    2003-01-01

    The workshop dealt with two distinct cases: - In Port Hope - an existing situation impacting a set of communities affected by the nuclear fuel industry since the 1930's. This situation concerns the remediation of soil 'tainted' by a low level of radioactivity resulting from the processing of uranium. The facility that produced those wastes is still in town but it has changed ownership and it no longer stores or disposes of the waste in the area. - The issuance and upcoming implementation of the Nuclear Fuel Waste Act (NWF Act) charting a path towards the identification of a national, long-term management solution for nuclear fuel (high level) waste in Canada. The NWF Act restarts a process that was interrupted a few years ago, after the Seaborn Environmental Assessment Panel concluded that the solution proposed by proponent Atomic Energy Canada Ltd. had not been demonstrated to have broad public support. From an international perspective, numerous observations can be made and lessons can be drawn both from the individual and the combined cases. Some of the most prominent observations, in the view of the NEA Secretariat, are presented hereafter. (author)

    2001-01-01

    This document (1) summarizes the most significant findings of the ''Qualification of Advanced Instrumentation and Control (I and C) Systems'' program initiated by the Nuclear Regulatory Commission (NRC); (2) documents a comparative analysis of U.S. and European qualification standards; and (3) provides recommendations for enhancing regulatory guidance for environmental qualification of microprocessor-based safety-related systems. Safety-related I and C system upgrades of present-day nuclear power plants, as well as I and C systems of Advanced Light-Water Reactors (ALWRs), are expected to make increasing use of microprocessor-based technology. The Nuclear Regulatory Commission (NRC) recognized that the use of such technology may pose environmental qualification challenges different from current, analog-based I and C systems. Hence, it initiated the ''Qualification of Advanced Instrumentation and Control Systems'' program. The objectives of this confirmatory research project are to (1) identify any unique environmental-stress-related failure modes posed by digital technologies and their potential impact on the safety systems and (2) develop the technical basis for regulatory guidance using these findings. Previous findings from this study have been documented in several technical reports. This final report in the series documents a comparative analysis of two environmental qualification standards--Institute of Electrical and Electronics Engineers (IEEE) Std 323-1983 and International Electrotechnical Commission (IEC) 60780 (1998)--and provides recommendations for environmental qualification of microprocessor-based systems based on this analysis as well as on the findings documented in the previous reports. The two standards were chosen for this analysis because IEEE 323 is the standard used in the U.S. for the qualification of safety-related equipment in nuclear power plants, and IEC 60780 is its European counterpart. In addition, the IEC document was published in

    The indicators of the efficiency of electrical installations are directly connected with the creating and using of new composite materials with the desired performance properties. The practical application of composite materials is one of the perspective scientific and technical directions, providing the increase of the efficiency of electrical installations due to the sealing of current parts by protecting them from the external medium. The technical characteristics of the composite material match to its structure and depend on the properties of the individual components. The verification of the compliance of material parameters is implemented by the methods of the computer analysis of a model of composite material in the form of the structure in which the individual elements have thermodynamic properties of the corresponding phase state. In the study the topology of individual elements in the material structure is defined by the conditional boundaries of the section within the studied composite. The efficiency of using the composite materials includes the raising of electrical safety, increasing the durability, reducing the costs of maintenance and repair and the extension of the scope of installations.

    Full Text Available This paper examines the different types of writing errors performed by 16 international postgraduate students undertaking an intensive English course at a public university in Malaysia. It was mandatory for international postgraduate students who obtained less than IELTS Band 6 to undertake an Intensive English Course (IEC offered by the University, prior to entering their respective faculties’ academic programs. The students were required to write a 3-5 page term paper assignment on a topic related to their field of study. Mixed methodology approach was employed to examine and analyze corpus of students’ term papers. The errors in the term papers were identified and classified accordingly. The results of the study revealed that four most common English language errors committed by the participants were sentence structure, articles, punctuation and capitalization. This study also shed light on the manner in which students assumed the rules of English to that of their native language. Such insight is useful for both instructors and students because it provides significant information on the building blocks experienced by English language learners in academic writing.

    Rowe, William A.

    1996-02-01

    Electronic visual displays have been evolving from the 1960's basis of cathode ray tube (CRT) technology. Now, many other technologies are also available, including both flat panels and projection displays. Standards for these displays are being developed at both the national level and the international levels. Standards activity within the United States is in its infancy and is fragmented according to the inclination of each of the standards developing organizations. The latest round of flat panel display technology was primarily developed in Japan. Initially standards arose from component vendor-to-OEM customer relationships. As a result, Japanese standards for components are the best developed. The Electronics Industries Association of Japan (EIAJ) is providing their standards to the International Electrotechnical Commission (IEC) for adoption. On the international level, professional societies such as the human factors society (hfs) and the International Organization for Standardization (ISO) have completed major standards, hfs developed the first ergonomic standard hfs-100 and the ISO has developed some sections of a broader ergonomic standard ISO 9241. This paper addresses the organization of standards activity. Active organizations and their areas of focus are identified. The major standards that have been completed or are in development are described. Finally, suggestions for improving the this standards activity are proposed.

    LD and LED are used in a wide range from telecommunication systems to residential/commercial equipment. Optical semiconductor devices existing in the domain between LD and LED are also being commercialized. In the field of this project, there are a lot of contradictions about the international standards. For the purpose of promoting the common understanding of standards and improving the consistency, the paper examined mainly safety, principles of motion and various applications of laser and LED, and developed international standards for the output measuring method. At the same time, the paper systematically studied the biological safety, determined regulatory values which were backed up as safety standards, and proposed/worked out a draft for new international standardization for safety of LED. Further, by the definition of laser in general, standards related to a lot of TCs among ISO and IEC standards were harmonized for the common understanding on the basis of a common idea. 40 refs., 163 figs., 6 tabs.
