    The opportunity cost of inappropriate health policy decisions is greater in Central and Eastern European (CEE) compared with Western European (WE) countries because of poorer population health and more limited healthcare resources. Application of health technology assessment (HTA) prior to healthcare financing decisions can improve the allocative efficiency of scarce resources. However, few CEE countries have a clear roadmap for HTA implementation. Examples from high-income countries may not be directly relevant, as CEE countries cannot allocate so much financial and human resources for substantiating policy decisions with evidence. Our objective was to describe the main HTA implementation scenarios in CEE countries and summarize the most important questions related to capacity building, financing HTA research, process and organizational structure for HTA, standardization of HTA methodology, use of local data, scope of mandatory HTA, decision criteria, and international collaboration in HTA. Although HTA implementation strategies from the region can be relevant examples for other CEE countries with similar cultural environment and economic status, HTA roadmaps are not still fully transferable without taking into account country-specific aspects, such as country size, gross domestic product per capita, major social values, public health priorities, and fragmentation of healthcare financing.

    The author discusses the legal evolutions related to nuclear safety between 2006 and 2010. He identifies three main topics of unequal importance. Firstly, he comments the implementation of an international reference framework which has been completed at the European level and which aims at the harmonization of safety and security rules. Secondly, he comments the creation of the French Nuclear Safety Authority (ASN, Autorite de Surete Nucleaire). Thirdly, he comments the recast of the standard framework in order to update the French law with respect to the international reference framework. This leaded to a new distribution of power and authority, to more complete and constraining procedures, and to the definition of procedures for each step of an installation life cycle

  11. Modelling turbulent fluid flows in nuclear and fossil-fired power plants; La modelisation des ecoulements turbulents rencontres dans les reacteurs nucleaires et dans les centrales thermiques a flamme

    Viollet, P.L.

    1995-06-01

    The turbulent flows encountered in nuclear reactor thermal hydraulic studies or fossil-fired plant thermo-aerodynamic analyses feature widely varying characteristics, frequently entailing heat transfers and two-phase flows so that modelling these phenomena tends more and more to involve coupling between several branches of engineering. Multi-scale geometries are often encountered, with complex wall shapes, such as a PWR vessel, a reactor coolant pump impeller or a circulating fluidized bed combustion chamber. When it comes to validating physical models of these flows, the analytical process highlights the main descriptive parameters of local flow conditions: tensor characterizing the turbulence anisotropy, characteristic time scales for turbulent flow particle dynamics. Cooperative procedures implemented between national or international working parties can accelerate validation by sharing and exchanging results obtained by the various organizations involved. With this principle accepted, we still have to validate the products themselves, i.e. the software used for the studies. In this context, the ESTET, ASTRID and N3S codes have been subjected to a battery of test cases covering their respective fields of application. These test cases are re-run for each new version, so that the sets of test cases systematically benefit from the gradually upgraded functionalities of the codes. (author). refs., 3 figs., 6 tabs.

    2009-02-15

    We present a new lock-free parallel algorithm for computing betweenness centralityof massive small-world networks. With minor changes to the data structures, ouralgorithm also achieves better spatial cache locality compared to previous approaches. Betweenness centrality is a key algorithm kernel in HPCS SSCA#2, a benchmark extensively used to evaluate the performance of emerging high-performance computing architectures for graph-theoretic computations. We design optimized implementations of betweenness centrality and the SSCA#2 benchmark for two hardware multithreaded systems: a Cray XMT system with the Threadstorm processor, and a single-socket Sun multicore server with the UltraSPARC T2 processor. For a small-world network of 134 million vertices and 1.073 billion edges, the 16-processor XMT system and the 8-core Sun Fire T5120 server achieve TEPS scores (an algorithmic performance count for the SSCA#2 benchmark) of 160 million and 90 million respectively, which corresponds to more than a 2X performance improvement over the previous parallel implementations. To better characterize the performance of these multithreaded systems, we correlate the SSCA#2 performance results with data from the memory-intensive STREAM and RandomAccess benchmarks. Finally, we demonstrate the applicability of our implementation to analyze massive real-world datasets by computing approximate betweenness centrality for a large-scale IMDb movie-actor network.

    / This study aims to investigate the ISO 14001 implementation process and its implications for regional environmental management. The region of Central Japan (known as Chubu in Japanese, which literally means center) was chosen for this case study. The study focuses on selected issues such as the: (1) trends and motives of private firms in the implementation of an ISO 14001-based environmental management system (EMS); (2) obstacles during system implementation; (3) role of the system in enhancing environmental performance within the certified organization; and (4) relation between the major stakeholders, local citizens, governments, and firms after adopting the system. To achieve these objectives, a questionnaire survey was mailed to all certified firms in the region. A 58% response was achieved overall. The results show that the main aims behind the adoption of ISO 14001 by firms in the Chubu region are to improve the environmental aspects within the enterprises and to enhance the employees' environmental awareness and capacity. The results have also shown that the ISO 14001-based EMS has had a great effect on a firm's environmental status as certified firms have claimed that natural resources such as fuel, water, and paper consumption have been more efficiently managed after adopting the system. Implementation of the system causes the firms to consider the role of the local people and the government in more effectively involving the local people in the firm's daily environmental activities. It also helps to enhance the environmental awareness among the local people. Adopting the system also promotes a better relation within the enterprises affiliated to the same group, such as more attention given by the parent firms (head offices) towards other firms working for the same group, or branches-mainly small and medium sized enterprises (SMEs)-in the field of EMS. Finally, the results show that firms give serious consideration to their final products' impacts on the

    Full Text Available In greenhouse culture, in addition to increasing the quantity and quality of crop production in comparison with traditional methods, the agricultural inputs are saved, too. Recently, using new methods, designs and materials, and higher automation in greenhouses, better management has become possible for enhancing yield and improving the quality of greenhouse crops. The constructed and evaluated central controller unit (CCU is a central controller system and computerized monitoring unit for greenhouse application. Several sensors, one CCU, several operators, and a data-collection and recorder unit were the major components of this system. The operators included heating, cooling, spraying, ventilation and lighting systems, and the sensors are for temperature, humidity, carbon dioxide, oxygen and light in inside and outside the greenhouse. Environmental conditions were measured by the accurate sensors and transmitted to the CCU. Based on this information, the CCU changed variables to optimize the greenhouse environmental conditions to predetermined ranges. This system was totally made of local instruments and parts and had the ability to integrate with the needs of the client. The designed and implemented CCU was tested in a greenhouse located in Agriculture and Natural Resources Research Center of Khuzestan Province during summer season of 2011. The CCU was operated successfully for controlling greenhouse temperature in the range of 22-29 ˚C, relative humidity of 35-55%, artificial lighting in the case of receiving radiation of less than 800 Lux and turning on the ventilation units if the concentration of carbon dioxide was more than 800 mg/L.

    2016-01-01

    Central line-associated bloodstream infection (CLABSIs) is an important healthcare-associated infection in the critical care units. It causes substantial morbidity, mortality and incurs high costs. The use of central venous line (CVL) insertion bundle has been shown to decrease the incidence of CLABSIs. Our aim was to study the impact of CVL insertion bundle on incidence of CLABSI and study the causative microbial agents in an intensive care unit in Kuwait. Surveillance for CLABSI was conducted by trained infection control team using National Health Safety Network (NHSN) case definitions and device days measurement methods. During the intervention period, nursing staff used central line care bundle consisting of (1) hand hygiene by inserter (2) maximal barrier precautions upon insertion by the physician inserting the catheter and sterile drape from head to toe to the patient (3) use of a 2% chlorohexidine gluconate (CHG) in 70% ethanol scrub for the insertion site (4) optimum catheter site selection. (5) Examination of the daily necessity of the central line. During the pre-intervention period, there were 5367 documented catheter-days and 80 CLABSIs, for an incidence density of 14.9 CLABSIs per 1000 catheter-days. After implementation of the interventions, there were 5052 catheter-days and 56 CLABSIs, for an incidence density of 11.08 per 1000 catheter-days. The reduction in the CLABSI/1000 catheter days was not statistically significant (P=0.0859). This study demonstrates that implementation of a central venous catheter post-insertion care bundle was associated with a reduction in CLABSI in an intensive care area setting. PMID:26138518

    2014-05-01

    The U.S. Bureau of Reclamation has identified the Rio Grande basin within Central New Mexico as one of several regions where water supplies are over-allocated and future conflicts over the inadequate resource are highly likely. Local water providers have consistently identified managed aquifer recharge (MAR) as an important tool to provide conjunctive management of surface-water, groundwater, and reclaimed water sources in order to extend the useful life of existing water sources. However, MAR projects have been slow to take root partly due to rigorous demonstration requirements, groundwater quality protection concerns, and ongoing water right uncertainties. At first glance the several thousand meters of unconsolidated basin-fill sediments hosting the regional aquifer appear to provide an ideal environment for the subsurface storage of surplus water. However, the basin has a complex structural and depositional history that impacts the siting and overall effectiveness of MAR systems. Several recharge projects are now in various stages of implementation and are overcoming site specific challenges including source water and ambient groundwater compatibility, low-permeability sediments and compartmentalization of the aquifer by extensive faulting, well clogging, and overall water quality management. This presentation will highlight ongoing efforts of these water providers to develop full-scale recharge facilities. The performance of natural in-channel infiltration, engineered infiltration galleries, and direct injection systems designed to introduce from 500 to 5,000 mega-liters per annum to target intervals present from 150 to 600 meters below ground surface will be described. Source waters for recharge operations include inter-basin transferred surface water and highly treated reclaimed water sources requiring from minor to extensive treatment pre-recharge and post-recovery. Operational complexities have raised concerns related to long-term operation and maintenance

  5. Organization of central database for implementation of ionizing radiation protection in the Republic of Croatia

    International Nuclear Information System (INIS)

    The paper is intended to give an overview of the situation in the Republic of Croatia resulting from passing of the new ionizing radiation protection law. Data collecting organization and records keeping structure will be highlighted in particular, as well as data exchange between individual services involved in ionizing radiation protection. The Radiation Protection Act has been prepared in compliance with the international standards and Croatian regulations governing the ionizing radiation protection field. Its enforcement shall probably commence in October 1999, when the necessary bylaws regulating in detail numerous specific and technical issues of particular importance for ionizing radiation protection implementation are expected to be adopted. Within the Croatian Government, the Ministry of Health is charge of ionizing radiation protection. Such competence is traditional in our country and common throughout the world. This Ministry has authorized three institutions to carry out technical tasks related to the radiation protection, such as radiation sources inspections and personal dosimetry. Such distribution of work demands coordination of all involved institutions, control of their work and records keeping. The Croatian Radiation Protection Institute has been entrusted to coordinate work of these institutions, control their activities, and set up the central national registry of radiation sources and workers, as well as doses received by the staff during their work. Since the Croatian Radiation Protection Institute is a newly established institution, we could freely determine our operational framework. Due to its publicly accessible source code and wide base of users and developers, the best prospective for stability and long-term accessibility is offered by the Linux operating system. For the database development, Oracle RDBMS was used, partly because it is a leading manufacturer of database management systems, and partly because our staff is very familiar

    Full Text Available Supportive organizational culture for knowledge management can vouch for successful implementation of knowledge management. In the case of lacking this kind of supportive culture, the organizational culture is one of the obstacles which can lead the implementation of knowledge management to full failure and waste of organizational assets. In this research, a framework based on FMCDM was utilized to assess the cultural readiness of organization as the knowledge management implementation prerequisite. This framework has been utilized to assess Central Bank of Iran’s cultural readiness. The methodology of research was descriptive and research data were gathered by questionnaire and were answered by experts and CBI executives. In this term, the cultural readiness of CBI was assessed and in accordance with this assessment, embarking on corrective action was proposed.

    In our report we describe concept, strategies and implementation of a central biosample and data management (CSDM) system in the three-centre clinical study of the Transregional Collaborative Research Centre "Inflammatory Cardiomyopathy - Molecular Pathogenesis and Therapy" SFB/TR 19, Germany. Following the requirements of high system resource availability, data security, privacy protection and quality assurance, a web-based CSDM was developed based on Java 2 Enterprise Edition using an Oracle database. An efficient and reliable sample documentation system using bar code labelling, a partitioning storage algorithm and an online documentation software was implemented. An online electronic case report form is used to acquire patient-related data. Strict rules for access to the online applications and secure connections are used to account for privacy protection and data security. Challenges for the implementation of the CSDM resided at project, technical and organisational level as well as at staff level. PMID:18406002

  10. The Implementation of Performance Management in European Central Governments: More a North-South than an East-West Divide

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available This article presents the first country-comparative evidence on the importance and use of performance management in European central governments, based on an executive survey conducted in 17 countries. The data confirm that performance management has made its way into European central governments and continues to constitute a major reform trend. At the organizational level of ministries and agencies we find a consistently strong use of strategic planning, performance appraisal and management objectives, along with only a partial institutionalization of a performance-management logic. Scepticism towards measurement and the difficulty of acting upon performance information are persistent challenges. We also find that performance-management implementation is significantly stronger in agencies and larger organizations, and that it varies strongly between different countries. Implementation is substantially higher in Scandinavian countries and Anglo-Saxon countries than in Continental and Southern European countries, with a rather varied pattern for Central and Eastern European countries. The findings thereby confirm the need for a more context-sensitive understanding of performance management, along with the need for more extensive research and evidence to further develop this cross-comparative European perspective.

  11. A literature review of the regional implementation of the central Swedish government's health care reforms on choice and privatization.

    2015-12-01

    The introduction in 2010 of the Freedom of Choice Act represents one of the most far-reaching reforms of the Swedish health system. While it is mandatory for the regional counties to introduce choice plans for primary care it is voluntary for ambulatory specialist services. The voluntary nature of the regulations for the latter types of care generates a potential gap between the central government's reform attempts and the regional implementation of the plans. We review the regional implementation of this reform with respect to specialist services from a political economy perspective. Data on the scope of implementation show that counties of the same political ideology as the central government have introduced the most choice plans for specialist care. In particular, counties ruled by right-wing majorities have introduced the Choice Act to a considerably larger extent than left-wing counties. This creates a highly uneven situation across the various parts of the country, possibly at odds with the basic premises of the country's health law of equal access to care. The introduction of choice plans forms part of a decidedly contentious set of issues that are high on the political agenda of Sweden. The nature and impacts of these reforms are also a concern to the general public and the broader industry. Considerably more rigorous analyses will be needed to assess the impact on key policy parameters such as overall system efficiency and equitable access to services as a result of these changes to the health care markets.

    2013-04-01

    As result of the gradually increasing nanotechnology sector there is the necessity of a contemporary analysis of the present regulations used for nanomaterials, to outline the current situation of the nanotechnology sector, to promote international cooperation and research's coordination to overcome disciplinary boundaries, to fill the gap between more and less experienced regions and to turn investments in R&D in industrial innovations. The general objective of the Central Europe project NANOFORCE, which is developed by national and regional chemistry associations and R&D Centres of the Central Europe area, is to foster the innovative nanotechnology-sector networks across Central Europe regions by bringing together public and private organizations to carry out collaborative and interdisciplinary researches on nanomaterials (in the frame of REACH Regulation) and to turn the most promising laboratory results into innovative industrial applications. To build up a legal advisory board for chemical enterprises starting in nanotechnology, a state of the art report on existing safety procedures and nanotech related regulations was produced to give an overview on currently available regulations used by chemical industries and manufacturing companies within the European region to secure their products. The main emphasis was placed on REACH regulation to search for relevant sections concentrating on nanomaterials which are applicable for nanotechnology. In addition, all relevant directives and amendments of REACH were screened with regard to identify gaps where action is still needed and give possible recommendations for the European Commission. Beyond literature research a questionnaire for producers, users, researchers and financiers was developed with the goal to collect information about the nanotechnology sector in the CE region concerning development, financial status, and international cooperation within joint ventures, safety and nanotoxicology.

    2016-01-01

    In an effort to take advantage of the Highmark Quality Blue Initiative () requiring information from hospitals detailing their central line-associated blood stream infections (CLABSIs) surveillance system, quality improvement program, and statistics regarding the CLABSI events, this institution investigated the latest evidence-based recommendations to reduce CLABSIs. Recognizing the baseline rate of 2.4 CLABSIs per 1,000 central line days and its effect on patient outcomes and medical costs, this hospital made a commitment to improve their CLABSI outcomes. As a result, the facility adopted the Society for Healthcare Epidemiology of America (SHEA) guidelines. The purpose of this article is to review the CLABSI rates and examine the prevention strategies following implementation of the SHEA guidelines. A quantitative, descriptive retrospective program evaluation examined the hospital's pre- and post-SHEA implementation methods of decreasing CLABSIs and the subsequent CLABSI rates over 3 time periods. Any patient with a CLABSI infection admitted to this hospital July 2007 to June 2010 (N = 78). CLABSI rates decreased from 1.9 to 1.3 over the study period. Compliance with specific SHEA guidelines was evaluated and measures were put into place to increase compliance where necessary. CLABSI rates at this facility remain below the baseline of 2.4 for calendar year 2013 (0.79), 2014 (0.07), and 2015 (0.33). PMID:27618377

  20. Implementation of decision support system in the central AQUATOOL Department of Valle del Cauca

    International Nuclear Information System (INIS)

    The decision support system AQUATOOL, created by the Polytechnic University of Valencia (Spain), represents an alternative for water resources management for it makes it possible to evaluate planning scenarios for the use of both surface and groundwater. For the evaluation of this tool, the application zone chosen was the Central Region of the Valle del Cauca State in Colombia. With the mathematical model AQUATOOL technical scenarios were formulated focused on the efficient satisfaction of demands in the zone, based on a supply - demand scheme, in which only real demand was included in the regulations for the use of every stream. As far as surface waters are concerned, a special feature of the State concerns its torrential flow rivers, not regulated. Though there are feasibility studies for regulation dams in the zone. Based on this initial scheme several alternatives were presented: aquifer swell and study of dams projected as complementary supply resources, aiming to greater satisfaction of present and future demands.

    Today's dynamic health care environment is exceedingly complex, and health care facilities across the United States are struggling to respond to changes in technology, health care reimbursement, the Affordable Care Act, and the much-anticipated nursing shortage. Mergers, acquisitions, and integrations are the current health care reality. These are proposed to increase efficiency, efficacy, quality, satisfaction, and safety while effectively reducing cost to the consumer and stabilizing the economy of the health care system. Many of these projects fail to achieve objectives, even years after the formal change in status. Clinical education departments in merged organizations are often operated in the single-facility mindset, or contain an element of the shared services model. They are not truly integrated. Development of skills in complex analysis of current state, identification of desired scope of service and expectations of performance, and articulation of the benefits of the desired future state are all essential to nursing executive practice. This article describes an experience integrating 3 legacy education departments across 21 facilities into a centralized education system. The complexity of integration activities is illustrated and outcome measures of success are discussed. Barriers, facilitators, and risks of the project are identified and evaluated. PMID:27584894

    Full Text Available Data warehouse is a set of integrated databases deliberated to expand decision-making and problem solving, espousing exceedingly condensed data. Data warehouse happens to be progressively more accepted theme for contemporary researchers with respect to contemporary inclination towards industry and executive purview. The crucial tip of the proposed work is integrated on delivering an enhanced and an exclusive innovative model based on the intention of enhancing security measures, which at times have been found wanting and also ensuring improved accessibility using Hashing modus operandi. An unsullied algorithm was engendered using the concept of protein synthesis, prevalently studied in Genetics, that is, in the field of Biotechnology, wherein three steps are observed, namely; DNA Replication, Translation and Transcription. In the proposed algorithm, the two latter steps, that is, Translation and Transcription have been taken into account and the concept have been used for competent encryption and proficient decryption of data. Central Dogma Model is the name of the explicit model that accounts for and elucidates the course of action for Protein Synthesis using the Codons which compose the RNA and the DNA and are implicated in numerous bio–chemical processes in living organisms. It could be observed that subsequently a dual stratum of encryption and decryption mechanism has been employed for optimal security. The formulation of the immaculate Hashing modus operandi ensure that there would be considerable diminution of access time, keeping in mind the apt retrieval of all indispensable data from the data vaults. The pertinent appliance of the proposed model with enhanced security might be in its significant service in a variety of organizations where accrual of protected data is of extreme magnitude. The variety of organizations might include educational organizations, corporate houses, medical establishments, private establishments and so on

    In their 2012 report, the President's Council of Advisors on Science and Technology advocated "replacing standard science laboratory courses with discovery-based research courses"-a challenging proposition that presents practical and pedagogical difficulties. In this paper, we describe our collective experiences working with the Genomics Education Partnership, a nationwide faculty consortium that aims to provide undergraduates with a research experience in genomics through a scheduled course (a classroom-based undergraduate research experience, or CURE). We examine the common barriers encountered in implementing a CURE, program elements of most value to faculty, ways in which a shared core support system can help, and the incentives for and rewards of establishing a CURE on our diverse campuses. While some of the barriers and rewards are specific to a research project utilizing a genomics approach, other lessons learned should be broadly applicable. We find that a central system that supports a shared investigation can mitigate some shortfalls in campus infrastructure (such as time for new curriculum development, availability of IT services) and provides collegial support for change. Our findings should be useful for designing similar supportive programs to facilitate change in the way we teach science for undergraduates. PMID:25452493

  5. A multi-institutional approach to implement fruit fly low prevalence and free areas in Central America: Outcomes and constraints

    International Nuclear Information System (INIS)

    Full text: For the purpose of boosting the fruit and vegetable exports of the Central American countries through fruit fly suppression/eradication actions, new approaches are used: - A multilateral alliance instead of isolated efforts. Thus, four international organisations, two donors Government institutions and the region's seven countries joined their efforts, coordinated by the IAEA; - A strategy of incremental enlargement of isolated low prevalence or free areas, instead of the old approach of attempting to eradicate the pest from the entire region; and - The use of pilot experimental areas, on which all elements that play a key role in a pest-free production-exports system are applied, instead of focusing only on some technologies in the field. Outcomes include the implementation of medfly-free areas in Honduras, Nicaragua and Costa Rica, and Panama is also in the process of doing so. Guatemala is presently negotiating with the Mexican Government the export of peach from its fruit fly-free zone in the Department of Quetzaltenango. Major constraints encountered are: - Weak alliances among the international organisations, - Troublesome coordination between Governments and the producers-exporters, - Insufficient trained civil servants in the Government and, - Insufficient funding to transfer the actions to bigger areas.

    titre d'exemple nous avons traite le probleme des usines de traitement de l'uranium naturel irradie associees a des centrales nucleaires a uranium naturel-graphite CO{sub 2}. La localisation et la production annuelle des reacteurs, les sites possibles d'usines et les fonctions de cout (transport et retraitement) sont supposes connus. La methode consiste a traiter d'abord le probleme des usines de traitement comme un probleme de programmation dynamique, des tranches croissantes de programmes (production totale des reacteurs) etant explorees sequentiellement. Lorsque les quantites d'uranium naturel irradie a retraiter sont fixees, la minimisation du cout de transport est alors effectuee, elle aussi comme un probleme de programmation dynamique. On explore le voisinage de l'optimum du cout de traitement pour trouver le minimum de la somme d'un cout de traitement sous-optimal et du cout de transport optimal correspondant. Le probleme de retraitement etant representable sur un graphe sequentiel, l'algorithme utilise pour calculer les sous-optima est 'l'algorithme a reflexion' que nous avons elabore. La methode s'interprete comme un mecanisme general de determination de l'optimum lorsque, a un probleme dynamique sequentiel (par exemple un programme d'equipement), se superpose un probleme complementaire (par exemple de transport). Elle permet en outre d'evaluer les pertes resultant du choix, pour des raisons autres qu'economiques, d'une politique non optimale. (auteur)

    2012-11-01

    Full Text Available Abstract Background Tanzania is experiencing acute shortages of Health Workers (HWs, a situation which has forced health managers, especially in the underserved districts, to hastily cope with health workers’ shortages by adopting task shifting. This has however been due to limited options for dealing with the crisis of health personnel. There are on-going discussions in the country on whether to scale up task shifting as one of the strategies for addressing health personnel crisis. However, these discussions are not backed up by rigorous scientific evidence. The aim of this paper is two-fold. Firstly, to describe the current situation of implementing task shifting in the context of acute shortages of health workers and, secondly, to provide a descriptive account of the potential opportunities or benefits and the likely challenges which might ensue as a result of implementing task shifting. Methods We employed in-depth interviews with informants at the district level and supplemented the information with additional interviews with informants at the national level. Interviews focussed on the informants’ practical experiences of implementing task shifting in their respective health facilities (district level and their opinions regarding opportunities and challenges which might be associated with implementation of task shifting practices. At the national level, the main focus was on policy issues related to management of health personnel in the context of implementation of task shifting, in addition to seeking their opinions and perceptions regarding opportunities and challenges of implementing task shifting if formally adopted. Results Task shifting has been in practice for many years in Tanzania and has been perceived as an inevitable coping mechanism due to limited options for addressing health personnel shortages in the country. Majority of informants had the concern that quality of services is likely to be affected if appropriate policy

    Paragangliomas (PGL) are relatively rare neural crest tumors originating in the adrenal medulla (usually called pheochromocytoma), chemoreceptors (i.e., carotid and aortic bodies) or autonomic ganglia. These tumors are highly vascular, usually benign and slow-growing. PGL may occur as sporadic or familial entities, the latter mostly in association with germline mutations of the succinate dehydrogenase (SDH) B, SDHC, SDHD, SDH5, von Hippel-Lindau (VHL), ret proto-oncogene (RET), neurofibromatosis 1 (NF1) (von Recklinghausen's disease), prolyl hydroxylase domain protein 2 (PHD2) genes and TMEM127. Molecular nuclear imaging has a central role in characterization of PGL and include: somatostatin receptor imaging ({sup 111}In, {sup 68}Ga), MIBG scintigraphy ({sup 131}I, {sup 123}I), {sup 18}F-dihydroxy-phenylalanine ({sup 18}F-DOPA) positron emission tomography (PET), and {sup 18}F-deoxyglucose ({sup 18}F-FDG) PET.

    The different meanings of the word 'energy', as understood by economists, are reviewed and explained. Present rates of consumption of fossil and nuclear fuels are given as well as corresponding reserves and resources. The time left before exhaustion of these reserves is calculated for different energy consumption scenarios. On finds that coal and nuclear only allow to reach the end of this century. Without specific dispositions, the predicted massive use of coal is not compatible with any admissible value of global heating. Thus, we discuss the clean coal techniques, including carbon dioxide capture and storage. One proceeds with the discussion of availability and feasibility of renewable energies, with special attention to electricity production. One distinguishes controllable renewable energies from those which are intermittent. Among the first we find hydroelectricity, biomass, and geothermal and among the second, wind and solar. At world level, hydroelectricity will, most probably, remain the main renewable contributor to electricity production. Photovoltaic is extremely promising for providing villages remote deprived from access to a centralized network. Biomass should be an important source of bio-fuels. Geothermal energy should be an interesting source of low temperature heat. Development of wind energy will be inhibited by the lack of cheap and massive electricity storage; its contribution should not exceed 10% of electricity production. Its present development is totally dependent upon massive public support. A large part of this paper follows chapters of the monograph 'L'energie de demain: technique, environnement, economie', EDP Sciences, 2005. (author)

    The overall objective of the CASINDO programme is to establish a self-sustaining and self-developing structure at both the national and regional level to build and strengthen human capacity to enable the provinces of North Sumatra, Yogyakarta, Central Java, West Nusa Tenggara and Papua to formulate sound policies for renewable energy and energy efficiency and to develop and implement sustainable energy projects. Energy has a very important role and has become a basic necessity in national sustainable development. Therefore, energy should be used sparingly and in a rational manner so that present and future energy demand can be met. Given the importance of using energy efficiently Government needs to devise a framework regulating the utilization of energy resources through the efficient application of technology and stimulating energy-saving behaviours. The purpose of this technical working group in CASINDO project is to research the steps and policy measures needed to improve the efficiency of electrical energy consumption in the household, industrial, and commercial buildings sector for Central Java. The government's efforts in promoting energy efficiency in Indonesia are still hampered by public awareness factor. This study exists to promote public awareness of energy efficiency by describing the financial benefits and possibilities of savings energies in order to support the government's energy saving program, replacement of old equipment that uses high power consumption with a new low-power one, reduction of unnecessary lighting, appreciation to the people who find and develop energy-efficient power utilization, persuade industries to uses the speed controller driver for production and fan motor to streamline the electrical energy usage.

    Full Text Available Abstract Background In middle income countries the number of trained health technology assessment specialists is limited and the public budget for health technology assessment is considerably lower compared to developed countries. These countries therefore must develop their own solutions to improve the quality and efficiency of health technology assessment implementation in reimbursement decisions. Our study aimed to develop a scientifically rigorous and detailed appraisal checklist for economic evaluations of pharmaceuticals in the single health technology assessment process. Methods The research design entailed a review of economic evaluations, submitted for reimbursement of pharmaceuticals, by two independent academic reviewers to identify the most common methodological problems. Fifty economic evaluations submitted in 2007-2008, randomly selected by the Health Technology Assessment Office served as data sources. The new checklist was developed by an iterative working process: first by assessing ten economic evaluations, then improving the checklist by generating new question items, then employing the improved checklist to assess the next ten economic evaluations. After appraising 25 documents, the reviewers reconciled their opinions and improved the checklist with the researchers of the Health Technology Assessment Office during an expert panel discussion.

    In studying the competitiveness of a nuclear merchant vessel, economic assessments in terms of figures were discarded in favor of a simplified model, which gives a clearer idea of the mechanism of the comparison between alternative vessels and the particular influence of each parameter. An expression is formulated for the unit cost per ton carried over a given distance as a function of the variables (speed and deadweight tonnage) and is used to determine the optima for conventional and nuclear vessels. To represent the freight market involved in the optimization studies, and thus in the competitiveness computation, two cases are taken into account: the tonnage to be carried annually is limited, and the tonnage to be carried annually is not limited. In both cases the optima are calculated and compared for a conventional and a nuclear vessel. Competitiveness curves are plotted as a function of the ratios of nuclear and conventional fuel costs and nuclear and conventional marginal power costs. These curves express the limiting values of the above two ratios for which the transport costs of the nuclear and conventional vessels are equal. The competitiveness curves vary considerably according to the hypothesis adopted for the freight market and the limit of tonnage carried annually.

    Can-rupture detection (DRG) is one important aspect of pile safety, more particularly so in the case of gas-cooled reactors. A rapid and sure detection constitutes also an improvement as far as the efficiency of electricity-producing nuclear power stations are concerned. Among the numerous can-rupture detection methods, that based on the measurement of the concentration of short-lived fission gases in the heat-carrying fluid has proved to be the most sensitive and the most rapid. A systematic study of detectors based on the electrostatic collection of the daughter products of fission gases has been undertaken with a view to equip the reactors EL 2, G 3, EDF 1, EDF 2 and EDF 3, the gas loops of PEGASE and EL 4. The different parameters are studied in detail in order to obtain a maximum sensitivity and to make it possible to construct detection devices having the maximum operational reliability and requiring the minimum maintenance. The primary applications of these devices are examined in the case of the above-mentioned reactors. (author) [French] La Detection des Ruptures de Gaines (D. R.

Parmi les nombreuses methodes de detection des ruptures de gaines, la mesure de la concentration dans le fluide caloporteur des gaz de fission a vie courte s'est revelee comme la plus sensible et la plus rapide. Une etude systematique des detecteurs a collection electrostatique des descendants des gaz de fission a ete entreprise en vue d'equiper les piles EL 2, G 3, EDF 1, EDF 2 et EDF 3, les boucles a gaz de la pile Pegase et la pile EL 4.

  5. Dosimeter calibration facilities and methods at the Radiation Measurement Laboratory of the Centre d'etudes nucleaires, Grenoble

    International Nuclear Information System (INIS)

    At the Centre d'etudes nucleaires, Grenoble, the Radiation Measurement Laboratory, which forms part of the Environmental Protection and Research Department, serves the entire Centre for purposes of dosimetry and the calibration of dose meters. The needs of radiation protection are such that one must have facilities for checking periodically the calibration of radiation-monitoring instruments and developing special dosimetry techniques. It was thought a good idea to arrange for the dosimetry and radiation protection team to assist other groups working at the Centre - in particular, the staff of the biology and radiobiology laboratories - and also bodies outside the framework of the French Commissariat a l'energie atomique. Thus, technical collaboration has been established with, for example, Grenoble's Centre hospitalier universitaire (university clinic), which makes use of the facilities and skills available at the Radiation Measurement Laboratory for solving special dosimetry problems. With the Laboratory's facilities it is possible to calibrate dose meters for gamma, beta and neutron measurements

  6. Economic consequences of the Swiss 'Sortir du nucleaire' and 'Moratoire-plus' popular initiatives - Analysis using a balanced model

    International Nuclear Information System (INIS)

    This article is a short version of the ENET number 210359. This report for the Swiss Federal Office of Energy (SFOE) presents the results of a study made to assess the economic consequences of two models for the opting out of nuclear energy in Switzerland, as proposed in two popular initiatives. The 'Sortir du nucleaire' (electricity without atomic power) initiative calls for the shutting down of the existing nuclear power stations and the 'Moratoire-plus' initiative calls for a stop on the building of new atomic power stations for 10 years. The method used for assessing the costs and benefits resulting if the initiatives were accepted in a public vote is described. Basic assumptions made on further factors concerning the electricity and energy markets are discussed. Results of analyses made for various scenarios with respect to CO2 emissions are presented and include discussions on risk costs, effects on employment and welfare aspects

    As an immediate consequence of the Fukushima accident the French nuclear safety Authority (ASN) asked EDF to perform a complementary safety assessment for each nuclear power plant dealing with 3 points: 1) the consequences of exceptional natural disasters, 2) the consequences of total loss of electrical power, and 3) the management of emergency situations. The safety margin has to be assessed considering 3 main points: first a review of the conformity to the initial safety requirements, secondly the resistance to events overdoing what the facility was designed to stand for, and the feasibility of any modification susceptible to improve the safety of the facility. This article details the specifications of such assessment, the methodology followed by EDF, the task organization and the time schedule. (A.C.)

    The seismic risk taken into account during the sizing of the nuclear power plant of Fessenheim seems to have been under evaluated at this time. The revaluation of the seismic risk, as proposed, until this day by EDF in order to the third ten-year visit of the power plant, planned for 2009, leads to a significant under evaluation of the risk and then is not acceptable. The present expertise details point by point the weaknesses of these revaluation. The power plant has been sized in an elastic manner that is generally strongly for the safety side. It is imperative to proceed the most quickly as possible to a deep control of the seismic resistance of the power plant of Fessenheim and then after having proceeded to a revision of the seismic risk in taking into account the actual knowledge in this field.

Those concerning the greatest number of agents in the Centre are classified according to the categories corresponding to the different conditions of working. Thus, the most important are put forward. Then, the authors rapidly make a review of hazards which may have some special interest because they appear more specific of the nuclear energy or because they are the most frequently noted on the index cards of hazards. The case of the tributylphosphate is studied more precisely.

    The United Nations organisation and nuclear energy rose simultaneously, in 1945, to occupy an important place in the public eye. The spiritual succession of the League of Nations which had foundered during the war was taken up by the new organisation which sought to implant its political ideal in a more tangible reality, so that it might thereby be inspired by concrete and substantial objectives. This is one of the reasons for the existence of the dozen specialized agencies created by the family of the United Nations and dealing with Health, Culture, Agriculture, Finance, etc. Nuclear energy is one of these techniques. Becoming suddenly an important power factor and exploiting for itself the prestige of Science, it became the favorite domain for the growth of this new spirit, as much in its universal form in 1945 as in its more regional form which it was later to adopt. The achievements are numerous and of varying importance; they deserve te be studied carefully. (author) [French] L'organisation des Nations Unies et le nucleaire ont ete places simultanement, en 1945, au premier plan de la scene mondiale.

C'est une des raisons d'existence de la douzaine d'institutions specialisees gravitant dans la famille des Nations Unies et s'occupant de Sante, de Culture, d'Agriculture, de Finances, etc. Le nucleaire est l'une de ces techniques. Devenu soudainement un facteur primordial de puissance, Cristallisant a son benefice le prestige de la Science, c'etait un terrain de predilection pour le developpement du nouvel esprit, aussi bien sous la forme universelle de 1945, que sous les formes regionales qui ont vu le jour ensuite.

    International Nuclear Information System (INIS)

    The Institut National des Sciences et Techniques Nucleaires (INSTN) provides students with high scientific qualifications, professionals and engineers with specialized education in all disciplines related to nuclear energy applications. Academic courses and professional training sessions are designed to put students in direct contact with specialists of each discipline providing up-to-date knowledge and know-how. This mission is focused on nuclear science and technology, and one of its main features is the 'Nuclear Engineering degree' in France, also called 'Genie Atomique' course. It represents a 'specialized' course (Master after the masters degree in nuclear engineering) designed for engineers who can thereby acquire a broad view of sciences and techniques implemented in the nuclear energy sector based on a specific high level fundamental courses in disciplines such as reactor physics, thermal hydraulics and nuclear materials. The 'Genie Atomique' course is organized by INSTN in Saclay and Cadarache research centres for the 'civilian' students and in Cherbourg for the future officers and staff of nuclear submarines and aircraft carrier at the EAMEA military school. During the last period, industry representatives have clearly expressed their increasing need to engage high level engineers, educated in the field of nuclear engineering to face the new challenges of what is now called the 'Nuclear Renaissance'. INSTN together with University Paris Sud 11 developed a new master degree in nuclear engineering opened to students from France and abroad. The objective of this specialty is to provide in-depth training in the field of nuclear reactor physics for the purpose of using existing tools, developing and installing third-generation reactors, and designing and developing the future systems still known as 'integrated systems'.

  20. A project proposal for the implementation of Intensity Modulated Radiation Therapy (IMRT) for treatment of tumors of the central nervous system (CNS)

    International Nuclear Information System (INIS)

    Radiotherapy, together with the surgery, one of the essential therapeutic tools in the treatment of CNS tumors. The use of radiation, can be severe sequelae affecting quality of life of the patient, organs at risk receiving high dose and advanced technique of IMRT treatment planning and allows treatments shaped fields, especially when the target of radiation is irregular, with fewer side effects by limiting the dose in the tumor tissues and organs at risk and to allow us to increase the doses in the tumor .. So we decided to develop a protocol for the implementation of IMRT, taking into account that we have the appropriate equipment, trained staff to develop this technique. The main objective of this proposal is to allow us to establish the parameters necessary to perform IMRT, and then escalate the dose of radiation to the tumor, with reduced toxicity to healthy tissues. Inclusion criteria. It included 6 patients with histological diagnosis of CNS tumors, specifically astrocytomas grade II, III and IV, glioblastoma multiforme, where radiation is the main treatment, or associated with surgery. It excludes patients who have previously received radiation therapy or are unable to receive treatment without having movements that do not suffer another debilitating disease and to sign informed consent. Be held position and will be used as masks thermo deformed stun, then planning CT performed in all cases. Be designed later volumes (GTV, CTV and PTV, and OR, as established by the ICRU reports 52 and 60, the IAEA), will define the dose, and restrictions on healthy tissue technique is defined treatment according proposed objectives in the planning system. Once approved, is made conventional simulation, verification of the treatment plan on your computer with web plates and implementation of treatment in 1220 of INOR LINAC.

    The continuous spectra coming from several nuclear reactions with light nuclei were measured. The spectra can be explained by a two-step reaction mechanism; however, the reactions produced by {sup 6}Li are different. A mechanism was proposed to explain their spectra based on the following assumptions: {sup 6}Li makes a nuclear molecule with the target which subsequently breaks up in such a way that an {alpha} particle comes out with the kinetic energy that it has in the molecule. The calculated spectra and those measured are in good agreement. (author) [French] Nous avons mesure les spectres continus produits dans plusieurs reactions nucleaires avec des noyaux legers. A l'exception des spectres produits par {sup 6}Li, on a trouve qu'on pouvait expliquer ces spectres par le mecanisme des reactions en deux etapes. Nous avons propose un mecanisme pour expliquer les spectres produits par {sup 6}Li. On suppose que {sup 6}Li forme une molecule nucleaire avec la cible qui eclate ensuite de facon telle qu'une particule alpha de la molecule sort avec l'energie cinetique de son mouvement propre dans la molecule. Les spectres calcules avec ces hypotheses et les spectres mesures sont en bon accord. (auteur)

At the same time, regional effects of global climate change, major land use changes, a booming mining sector, and growing cities with insufficient and decaying water and wastewater infrastructures result in an increasingly unsustainable exploitation and contamination of ground and surface water resources putting at risk both aquatic ecosystems and human health. For the mesoscale (≈15,000 km2 model region of the Kharaa River Basin (KRB, we investigated (1 the current state of aquatic ecosystems, water availability and quality; (2 past and expected future trends in these fields and their drivers; (3 water governance structures and their recent reforms; and (4 technical and non-technical interventions as potential components of an integrated water resources management (IWRM. By now, the KRB is recognized as one of the most intensively studied river basins of the country, and considered a model region for science-based water resources management by the Mongolian government which recently adopted the IWRM concept in its National Water Program. Based on the scientific results and practical experiences from a six-year project in the KRB, the potentials and limitations of IWRM implementation under the conditions of data-scarcity are discussed.

  3. Designing and Implementing an OVERFLOW Reader for ParaView and Comparing Performance Between Central Processing Units and Graphical Processing Units

    2010-01-01

    In the Applied Aerosciences and CFD branch at Johnson Space Center, computational simulations are run that face many challenges. Two of which are the ability to customize software for specialized needs and the need to run simulations as fast as possible. There are many different tools that are used for running these simulations and each one has its own pros and cons. Once these simulations are run, there needs to be software capable of visualizing the results in an appealing manner. Some of this software is called open source, meaning that anyone can edit the source code to make modifications and distribute it to all other users in a future release. This is very useful, especially in this branch where many different tools are being used. File readers can be written to load any file format into a program, to ease the bridging from one tool to another. Programming such a reader requires knowledge of the file format that is being read as well as the equations necessary to obtain the derived values after loading. When running these CFD simulations, extremely large files are being loaded and having values being calculated. These simulations usually take a few hours to complete, even on the fastest machines. Graphics processing units (GPUs) are usually used to load the graphics for computers; however, in recent years, GPUs are being used for more generic applications because of the speed of these processors. Applications run on GPUs have been known to run up to forty times faster than they would on normal central processing units (CPUs). If these CFD programs are extended to run on GPUs, the amount of time they would require to complete would be much less. This would allow more simulations to be run in the same amount of time and possibly perform more complex computations.

    In 2011 the Smart Grid Network, established by the Danish Climate and Energy minister in 2010, published a report which identifies 35 recommendations for implementing smart grid in Denmark. The present report was prepared by the Danish Energy Association and Energinet.dk and elaborates three of these recommendations: Concept for controlling the power system; Information model for the dissemination of data; Roadmap for deployment of smart grid. Concept of Smart Grid: The concept mobilizes and enables electric power demand response and production from smaller customers. This is done by customers or devices connected to the power system modify their behavior to meet the needs of the power system. The concept basically distinguishes between two different mechanisms to enable flexibility. One is the use of price signals (variable network tariffs and electricity prices), which gives customers a financial incentive to move their electricity consumption and production to times when it is of less inconvenience to the power system.

Information Model for Disseminating Data: The future power system is complex with a large number of physical units, companies and individuals are actively involved in the power system. Similarly, the amount of information needed to be collected, communicated and processed grows explosively, and it is therefore essential to ensure a well-functioning IT infrastructure. A crucial element is a standardized information model in the Danish power system. The concept therefore indicates to use international standards to define an information model. Roadmap Focusing on Grid Companies' Role: There is a need to remove two key barriers. The first barrier is that the existing regulation does not support the grid using

    The source-oriented Weather Research and Forecasting chemistry model (SOWC) was modified to include warm cloud processes and was applied to investigate how aerosol mixing states influence fog formation and optical properties in the atmosphere. SOWC tracks a 6-D chemical variable (X, Z, Y, size bins, source types, species) through an explicit simulation of atmospheric chemistry and physics. A source-oriented cloud condensation nuclei module was implemented into the SOWC model to simulate warm clouds using the modified two-moment Purdue Lin microphysics scheme. The Goddard shortwave and long-wave radiation schemes were modified to interact with source-oriented aerosols and cloud droplets so that aerosol direct and indirect effects could be studied. The enhanced SOWC model was applied to study a fog event that occurred on 17 January 2011, in the Central Valley of California. Tule fog occurred because an atmospheric river effectively advected high moisture into the Central Valley and nighttime drainage flow brought cold air from mountains into the valley. The SOWC model produced reasonable liquid water path, spatial distribution and duration of fog events. The inclusion of aerosol-radiation interaction only slightly modified simulation results since cloud optical thickness dominated the radiation budget in fog events. The source-oriented mixture representation of particles reduced cloud droplet number relative to the internal mixture approach that artificially coats hydrophobic particles with hygroscopic components. The fraction of aerosols activating into cloud condensation nuclei (CCN) at a supersaturation of 0.5 % in the Central Valley decreased from 94 % in the internal mixture model to 80 % in the source-oriented model. This increased surface energy flux by 3-5 W m-2 and surface temperature by as much as 0.25 K in the daytime.

    This document proposes a methodology that reunites support tools for the operator of a Combined Cycle Generating Power Station allowing him to identify and to classify gas turbine faults, it also reunites some tools for the generation of action advices in the decision making on the operation maneuvers necessary to counteract the effects caused by faults. We are talking about a system implemented in a power station with the reconfiguration of processes and fault arrangement capacities. For this purpose, the line of exhibition delimits first the existing knowledge on automatic control and operations supervision systems in a CCPP and immediately emphasizes the cracks of the system to let pass to the fault tolerant active control system that will detect faults of the gas and steam turbo-generators of a Combined Cycle Generating Power Plant. [Spanish] El presente documento propone una metodologia que reuna herramientas de ayuda al operador de una Central Generadora de Electricidad de Ciclo Combinado para permitirle la identificacion y clasificacion de fallas en las turbinas de gas, asi como herramientas para la generacion de consejos de accion en la toma de decisiones sobre las maniobras de operacion necesarias para contrarrestar los efectos provocados por fallas. Se trata principalmente de un sistema implantado en una central con las capacidades de re-configuracion de procesos y acomodo de fallas. Para esto, la linea de exposicion delimita primero el conocimiento existente sobre sistemas automaticos de control y supervision de operacion en una CGCC y resalta enseguida las grietas del sistema para darle paso al sistema de control activo tolerante a fallas que detectara fallas de los turbogeneradores de gas y vapor de una Central Generadora de Electricidad de Ciclo Combinado.

  7. Complexity of Strong Implementability

    We consider the question of implementability of a social choice function in a classical setting where the preferences of finitely many selfish individuals with private information have to be aggregated towards a social choice. This is one of the central questions in mechanism design. If the concept of weak implementation is considered, the Revelation Principle states that one can restrict attention to truthful implementations and direct revelation mechanisms, which implies that implementability of a social choice function is easy to check. For the concept of strong implementation, however, the Revelation Principle becomes invalid, and the complexity of deciding whether a given social choice function is strongly implementable has been open so far. In this paper, we show by using methods from polyhedral theory that strong implementability of a social choice function can be decided in polynomial space and that each of the payments needed for strong implementation can always be chosen to be of polynomial encoding...

This article ex-plores the reasons for the budget violation from two angles:budget environment and budget implementation audit. According to the research of central budget implementation audit, we found that higher financial adequacy will induce higher ratio of budget violation, a higher degree of public concern will restrain budget violation, and the head of department’ s political power does not have influence on the budget violation, the budget implementation audit frequency and the degree of budget violation is negatively correlated. Therefore, it is imperative to optimize the preparation of the budget, improve budget disclosure and ac-celerate the full coverage of budget implementation audit.

    International Nuclear Information System (INIS)

    The radioactive contaminant materials resulting from diverse activities in relation to the nuclear fuel cycle, defence related operations, and various industries in addition to medical and research facilities represent perhaps the most severe and immense pollution left from a past era. The political changes in central and eastern Europe (CEE) not only brought some disclosure of the radioactively contaminated sites, but also resulted in a political condition in which this region became receptive to co-operation from a range of outside countries. The subjects of the first workshop held in Budapest, 4-8 October 1993, was the identification and characterization of radioactively contaminated sites in the region. The second part of the project and the second workshop (Piestany, Slovak Republic, 12-16 April 1994) involved planning and preparing the identified sites for restoration. This included items such as the restoration objectives, dose and environmental assessment, cost analysis, strategy and prioritization. Eventually, the third part of the project covered technologies for, and the implementation of, environmental restoration. The third and final workshop was held in Rez, Czech Republic, 12-16 December 1994. Refs, figs, tabs

    Since two years ago nuclear medicine service of Laennec Hospital has implemented transmission and distribution networks of scintigraphic images. A new stage was reached at present by developing an Intranet and Extranet system for nursing units and other services of nuclear medicine. The Intranet link to the services of Laennec Hospital and AP HP is based on a image server connected to the service gamma camera and, after a possible post-processing, the images are transmitted in PCX format by e-mail, attached to the medical record. For communication between nuclear medicine services, a heavier procedure making use of a program for image processing under inter-file standards has been implemented. To achieve the Extranet link with services and physicians of town, exterior to AP HP, a procedure was installed which allows reaching any nursing unit or town physicians having at their disposal e-mail on a secured network. This procedure will be generalized when the Health secured network, linking the medical bodies to Health insurance institutions, will be operational. The interactive tele-medicine will be achieved by means of a procedure based on Internet cooperative tools (wild cards, video- and vision-conferences) which will permits in all situations an interactive work on all the transmitted patient files

    This book presents a comprehensive survey, and a masterpiece in the debate, about one of the most controverted subject of the century, from the very first production of the absolute weapon to its recent comeback in force in the geopolitical scene, including the non-proliferation treaty and the difficulties to make it respected. The author has followed the international evolutions in this topic for more than 30 years and has gathered all existing facts about nuclear arsenals, governments declarations and actions, as well as the strategic, technological and ideological advances of the nuclear-military complex. Todays, the fear of nuclear weapons is omnipresent again and is exploited by both sides: those who claim for a complete dismantling of all types of nuclear weapons, and those who feel necessary to invest in the maintenance and renewal of existing arsenals together with fighting against proliferation. The central question is dissuasion: does it work in all circumstances, and from doing what nuclear arsenals dissuade today? (J.S.)

  18. CENTRAL PLATEAU REMEDIATION

    2006-02-01

    A systematic approach to closure planning is being implemented at the Hanford Site's Central Plateau to help achieve the goal of closure by the year 2035. The overall objective of Central Plateau remediation is to protect human health and the environment from the significant quantity of contaminated material that resulted from decades of plutonium production in support of the nation's defense. This goal will be achieved either by removing contaminants or placing the residual contaminated materials in a secure configuration that minimizes further migration to the groundwater and reduces the potential for inadvertent intrusion into contaminated sites. The approach to Central Plateau cleanup used three key concepts--closure zones, closure elements, and closure process steps--to create an organized picture of actions required to complete remediation. These actions were merged with logic ties, constraints, and required resources to produce an integrated time-phased schedule and cost profile for Central Plateau closure. Programmatic risks associated with implementation of Central Plateau closure were identified and analyzed. Actions to mitigate the most significant risks are underway while high priority remediation projects continue to make progress.

    In France, in application of the clean water law from January 3, 1992 and since the decree 95-540 from May 4, 1995, each basic nuclear facility receives a single permission which covers both its water takes and its radioactive and non-radioactive effluents. This decree, initially dedicated to new facilities has been enlarged to all existing installations for which the prefectorial by-laws have reached their date-line. Thus, up to now, five inter-ministerial by-laws have renewed the permissions of water takes and effluents evacuation of the power plants of Saint-Laurent-des-Eaux (Loir-et-Cher), Flamanville (Manche), Paluel (Seine-Maritime), Belleville (Cher) and Saint-Alban (Isere). These by-laws foresee an important abatement of the effluents and concern more particularly the tritium, {sup 14}C, the iodine isotopes and also some other non-radioactive chemical compounds. This document is a compilation of all revised by-laws about effluents and concerning the nuclear power plants listed above. (J.S.)

    The internal organisation for first aid to the injured in case of an accident on E.D.F. nuclear power plant calls for the immediate assistance of a first aid team, consisting of five workers, under the direction of a principal first aid officer; one of the first aid workers, the sanitary officer who instructs the first aid workers intervention awaiting the arrival of an external medical. When the 'Sanitary on-site Emergency Plan' was up' dated, twenty medical doctors and seventy members of staff from five different sites were questioned as to the function of the sanitary officer. The conclusions revealed a notable difference of training amongst the different sites, and concerning first aid organisation, difference of priority of actions, extent of their participation once the medical team arrives and their participation in case of decontamination treatment. The medical doctors and staff lay a particular stress on importance of defining on a national scale the limits of role and responsibilities of the sanitary officer and establish a more specific training in this field, consequently motivating commitment and professionalism involvement. There is a great difference between the training and coaching of the first aid assistance and fire protection teams. To conclude, we propose that the first aid officer be known as first aid coordinator and the qualification of 'Certificat de Formation aux Premiers Secours en Equipe' in compliance with the current legislation together with a specific nuclear module and they should undergo regular on-site drills.

Prior to this, he recalls the reasons which oblige physicians and engineers, even today, to use electronic machines in this domain. The author then considers the technological problems posed by the range of values which the various nuclear parameters adopt. In each case, he shows that a compromise is possible allowing an optimum precision. He compares the results to those obtained by arithmetic calculation and uses the examples chosen in a critical analysis of the present possibilities of the two methods of calculation.

    Full Text Available PNPM-Mandiri as community empowerment program is a national program to accelerate the poverty reduction. The implementation of the program in some areas showed the successful by the poverty reduction. Nevertheless, many areas failed in implementing the program showed by the poverty remains, even worse. Therefore, it needs further analysis whether successful of the implementation of the program could not automatically reduce the poverty rate. The problem was occured in Besito Village Gebog Sub-District Kudus Regency. BKM Besito Makmur, the community based organization in the Village, won Kudus Regency awards in some years and also from Provincial level, but the poverty rate is still relatively high. This research used qualitative method in analyzing the implementation of PNPM Mandiri Urban in Besito Village, a community empowerment project supported by World Bank joint funded by local community. Besides this research analyzed the effectiveness of PNPM - Mandiri in reducing the poverty, this research also analyzed the roles of stakeholders to reduce the poverty through PNPM - Mandiri, the constraining factors, and the result of program implementation. As a result of evaluation, this program seems to be failed in terms of poverty reduction as final goal. The poverty reduction in Besito Village cannot be achieved although the BKM won awards because the implementation of the program only good in administration. The roles of stakeholders were not optimal, since the poor, women, and community leaders were not involved in all activities especially in the planning stage. The constraining factors divided into two categories, structural problems and operational problems. The poverty alleviation program needs some improvement to be more effective, efficient, relevant, sustainable and give positive impact in reducing the poverty. To cope with, the poor should be centered in implementing the program. Keywords: Community Empowerment; Poverty Reduction

    Inelastic scattering of medium energy a particles by nuclei is known to excite preferentially levels of collective character. We have studied the scattering of isotopically enriched targets of Ca, Fe, Ni, Cu, Zn. In part I, we discuss the theoretical features of the interaction. In part II, we describe the experimental procedure. Results are presented and analysed in part III. {alpha} particles scattering by Ca{sup 40} is showed to excite preferentially odd parity levels. In odd nuclei we have observed multiplets due to the coupling of the odd nucleon with the even-even core vibrations. For even-even nuclei, a few levels are excited with lower cross-sections between the well-known first 2{sup +} and 3{sup -} states. Some could be members of the two phonon quadrupole excitation and involve a double nuclear excitation process. (author) [French] On sait que la diffusion inelastique des particules alpha de moyenne energie excite preferentiellement des niveaux de caractere collectif. Nous avons etudie la diffusion des particules alpha de 44 MeV du cyclotron de Saclay par des isotopes separes de Ca, Fe, Ni, Cu, Zn. Dans la premiere partie nous exposons les theories de cette interaction. Dans la seconde nous decrivons le systeme experimental. Les resultats sont donnes dans la troisieme partie. Nous montrons que les niveaux excites preferentiellement pour {sup 40}Ca par diffusion ({alpha},{alpha}') sont de parite negative. Dans les noyaux pair-impair nous avons observe des multiplets dus au couplage du nucleon celibataire avec les vibrations du coeur pair-pair. Pour les noyaux pair-pair nous avons pu etudier entre le premier niveau 2{sup +} et le niveau 3{sup -} deja bien connus certains etats plus faiblement excites. Il semble qu'ils sont dus a une excitation quadrupolaire a deux phonons et impliquent un processus de double excitation nucleaire. (auteur)

  15. Fusion Implementation

    International Nuclear Information System (INIS)

    If a fusion DEMO reactor can be brought into operation during the first half of this century, fusion power production can have a significant impact on carbon dioxide production during the latter half of the century. An assessment of fusion implementation scenarios shows that the resource demands and waste production associated with these scenarios are manageable factors. If fusion is implemented during the latter half of this century it will be one element of a portfolio of (hopefully) carbon dioxide limiting sources of electrical power. It is time to assess the regional implications of fusion power implementation. An important attribute of fusion power is the wide range of possible regions of the country, or countries in the world, where power plants can be located. Unlike most renewable energy options, fusion energy will function within a local distribution system and not require costly, and difficult, long distance transmission systems. For example, the East Coast of the United States is a prime candidate for fusion power deployment by virtue of its distance from renewable energy sources. As fossil fuels become less and less available as an energy option, the transmission of energy across bodies of water will become very expensive. On a global scale, fusion power will be particularly attractive for regions separated from sources of renewable energy by oceans

    Nuclear components require welds of irreproachable and reproducible quality. Moreover, for a given welding process, productivity requirements lead to reduce the volume of deposited metal and thus to use narrow gap design. In the shop, narrow gap Submerged Arc Welding process (SAW) is currently used on rotating parts in flat position for thicknesses up to 300 mm. Welding is performed with one or two wires in two passes per layer. In Gas Tungsten Arc Welding process (GTAW), multiple applications can be found because this process presents the advantage of allowing welding in all positions. Welding is performed in one or two passes per layer. The process is used in factory and on the nuclear sites for assembling new components but also for replacing components and for repairs. Presently, an increase of productivity of the process is sought through the use of hot wire and/or two wires. Concerning Gas Metal Arc Welding process (GMAW), its use is growing for nuclear components, including narrow gap applications. This process, limited in its applications in the past on account of the defects it generated, draws benefit from the progress of the welding generators. Then it is possible to use this efficient process for high security components such as those of nuclear systems. It is to be noted that the process is applicable in the various welding positions as it is the case for GTAW, while being more efficient than the latter. This paper presents the state of the art in the use of narrow gap mechanised arc welding processes by AREVA NP units.

    This document has the purpose of to share acquired experiences during the implementation of the Coaching project focused the training of supervisors and directive personnel of the nuclear power plant of Laguna Verde (NPP-L V). Derived of the improvement areas identified by the supervisor organization of the nuclear power stations WANO (World Association Nuclear of Operators) and of the auto-evaluations realized by the expert personnel of the same power station that based on external experiences carried out through the Benchmarking (comparison with other power stations) they have reflected the necessity to activate a training process in Coaching with a practical focus toward the directive and supervisor personnel in the power station. By means of the observation of the personnel's acting so much in the control rooms like in different areas, three focus areas have been identified for the training in Coaching, these are the personnel's motivation, the organizational communication so much in vertical form as horizontal and the perception of confidence lack among directive, supervisors, operators and technicians. The plan focused in the abilities training of Coaching with practical sense was development, supported with an evaluation of 360 grades as tool of competitions development through a computer application e-Coaching. The use of application and Coaching following techniques facilitated the conformation of the practical focus, same that are of continuous use starting from the training of the supervisor and directive personnel.

    In France, 76% of electricity is produced by nuclear power. The industry's pricing levels are among the most competitive in Europe. Thanks to its 58 nuclear reactors France enjoys almost 50% energy autonomy thus ensuring a highly stable supply. Equally, as a non-producer of greenhouse gases, the nuclear sector can rightfully claim to have an environmentally friendly impact. Against a background to increasing global demand with predictions that fossil fuels will run out and global warming a central issue, it is important to use production methods which face up to problems of this nature. There is no question that nuclear energy has a vital role to play alongside other energy sources. (authors)

    The TIBERE Model is a neutron leakage method based on B{sub 1} heterogeneous transport equation resolution. In this work, we have studied the influence of the reflection mode at the boundary of the assembly. In particular the White boundary condition has been implemented in the APOLLO2 neutron transport code. We have compared the two TIBERE kinds of boundary conditions (specular and white) with the classical B{sub 1} homogeneous leakage method in the modelling of some reactors. We have remarked the better capability of the TIBERE Model to compute voided assemblies. The white boundary condition is also able to compute a completely voided assembly and, besides, wins a factor 10 in CPU time in comparison with the specular boundary condition. These two heterogenous leakage formalisms have been tested on a partially voided experiment and have shown that the TIBERE Model can compute this kind of situation with a greater precision than the classical B{sub 1} homogeneous leakage method, and with a shorter computational time.

    The purpose of this work in-pile investigation of He formed by (n, 2n) and (n, {alpha}) nuclear reactions, released from irradiated BeO, in the temperature range 1000 - 1350 deg. C. The experimental results show that, for an instantaneous neutron fast flux of 10{sup 13} n cm{sup -2} sec{sup -1}, an equilibrium is attempted, after several days, for a part lower than 20 per cent of the quantity of He formed, theoretically calculated from the neutron cross sections of nuclear reactions, and from the analytical form of the neutron fast flux, releases from the solid. The validity of the values of calculated helium and the gas chromatographic analytical method are also verified by dissolution of the BeO pellets in cryolite. A new fast neutron flux measuring method may be so defined. The discussion of the experimental results enables to establish that the processus of He release is characterized by two phenomena: the first one which controls the release of He atoms out of the solid and the second which reveals a capture processus, connected to the irradiation and probably due to the vacancies induced in the lattice.

The activities being carried out within the entity at the time of the event were singular and the identified causes numerous, but were fundamentally the product of human and organizational factors. The lessons learnt from this event need to be shared with all other entities. Like many other less significant events that took place in 2005 and 2006, this event led the General Inspectorate to focus particularly on criticality risk control on sites where fissile material is used. It considers that internal criticality control actions must be carried out on these sites in order to make sure the required provisions are known and applied by all operators. In-service fire risk control hinges on - among other things - the application of fire prevention, protection and preparation rules, which must be a constant concern of site managers. The General Inspectorate noted numerous positive developments on most sites in this field in 2006, as well as the production entities' full cooperation with the risk analysis services and fire-fighting services. On most sites, fire risk control is organized clearly and in a structured manner.

  16. Central alarm system replacement in NPP Krsko

    International Nuclear Information System (INIS)

    Current NPP Krsko central alarm system consists of three main segments. Main Control Board alarm system (BETA 1000), Ventilation Control Board alarm system (BETA 1000) and Electrical Control Board alarm system (BETA 1100). All sections are equipped with specific BetaTone audible alarms and silence, acknowledge as well as test push buttons. The main reason for central alarm system replacement is system obsolescence and problems with maintenance, due to lack of spare parts. Other issue is lack of system redundancy, which could lead to loss of several Alarm Light Boxes in the event of particular power supply failure. Current central alarm system does not provide means of alarm optimization, grouping or prioritization. There are three main options for central alarm system replacement: Conventional annunciator system, hybrid annunciator system and advanced alarm system. Advanced alarm system implementation requires Main Control Board upgrade, integration of process instrumentation and plant process computer as well as long time for replacement. NPP Krsko has decided to implement hybrid alarm system with patchwork approach. The new central alarm system will be stand alone, digital, with advanced filtering and alarm grouping options. Sequence of event recorder will be linked with plant process computer and time synchronized with redundant GPS signal. Advanced functions such as link to plant procedures will be implemented with plant process computer upgrade in outage 2006. Central alarm system replacement is due in outage 2004.(author)

  3. Development of a general framework for the practical implementation of ALARA

    International Nuclear Information System (INIS)

    The concept of optimization of protection of the International Commission on Radiological Protection (ICRP) had its roots in the realization that radiation damage is not solely a threshold phenomenon, so a system of protection could not rely solely on limits. It was originally a qualitative idea that you did what was reasonable to reduce doses in the region below the limits. In Publication 26 of the ICRP the recommendation was in terms of ALARA (as low as reasonably achievable). It seems that there are still a number of problem areas and misconceptions about the practical implementation of ALARA, particularly the relationship between the ALARA requirement, decision-aiding techniques and decisions. The development of a general methodological framework for ALARA studies is primary objective of a joint project between the United Kingdom National Radiological Protection Board and the French Centre d'etude sur l'evaluation de la protection dans le domaine nucleaire, sponsored by the Biology and Health Protection programme of the Commission of the European Communities. Following a review of the underlying concepts, the paper outlines progress made on the general framework in a step-by-step guide to performing ALARA studies. The framework covers the initial structuring of the radiological protection problem; the identification of alternative protection options; the selection and quantification of relevant factors for each option; the use of decision-aiding techniques incorporating judgements on the relative weight assigned to these factors; and subsequent sensitivity analyses. This framework provides a method for carrying out ALARA studies to form a structured input to decisions involving non-radiological aspects. Each stage is described, highlighting problem areas where detailed technical guidance or value judgements are required. (author)

  4. Central Neuropathic Pain Syndromes.

    Watson, James C; Sandroni, Paola

    2016-03-01

    Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury. This review focuses on unique clinical features that help distinguish central neuropathic pain. The most common clinical central pain syndromes-central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain-are reviewed in detail. Recent progress in understanding of the pathogenesis of central neuropathic pain is reviewed, and pharmacological, surgical, and neuromodulatory treatments of this notoriously difficult to treat pain syndrome are discussed.

  9. Generation of central exclusive final states

    CERN Document Server

    Lönnblad, Leif

    2016-01-01

    We present a scheme for the generation of central exclusive final states in the Pythia 8 program. The implementation allows for the investigation of higher order corrections to such exclusive processes as approximated by the initial-state parton shower in Pythia 8. To achieve this, the spin and colour decomposition of the initial-state shower has been worked out, in order to determine the probability that a partonic state generated from an inclusive sub-process followed by a series of initial-state parton splittings can be considered as an approximation of an exclusive colour- and spin-singlet process. We use our implementation to investigate effects of parton showers on some examples of central exclusive processes, and find sizeable effects on di-jet production, while the effects on e.g. central exclusive Higgs production are minor.

    This paper presents the methodology for assessment of the storage capacity into a saline aquifer depth and the results of the studies carried out in the central east area of the Duero Basin. The extension of the study area represents about 40% of the basin. This methodology has been conducted under the need of estimate of uncertainty in everything related to behavior of long-term stored CO{sub 2} in geological formations because one of the major challenges associated with this activity is ensuring the retention of stored CO{sub 2} along the period of the required time. The method is based on the implementation of a Geographic Information System as a tool for capture, storage, management and presentation of data in maps, as well as a tool for analysis and modelling through its link to both geostatistical methods and description of CO{sub 2} thermodynamic behaviour in deep geological storage conditions, by using real gases Equations of States, specially the Sterner-Pitzer Cubic Equation of State. All these analyses are accompanied by the error propagation due to the calculations required for the determination of the volume of rock, the vertical accuracy of the topographic layers, as well as other uncertainties associated with the variables required for the characterization of the CO{sub 2} in the storage conditions. The conclusion is that the deep geologic CO{sub 2} storage capacity in the study area is between 1,667 and 11,976 Mt, i.e. between 11 and 81 years of storage capacity with a current spanish CO{sub 2} production of 148 Mt/year.

    In a power reactor destined to supply industrially recoverable thermal energy, the most economical source of heat still consists of natural metallic uranium. However, the nuclear fuel material, most often employed in the form of rods of 20 to 40 mm diameter, is subjected to a series of stresses which lead to irreversible distortions usually incompatible with the substructure of the reactor. As a result the fuel material must possess at the outset a certain number of qualities which must be determined. Investigations have therefore been carried out, first on the technological characters peculiar to each of the three allotropic phases of pure uranium metal, and on their interactions on the stabilisation of the material which consists of either cast uranium or uranium pile-treated in the {gamma} phase. (author) [French] Dans un reacteur de puissance destine a fournir de l'energie thermique industriellement recuperable, la source de chaleur la plus economique reste constituee par de l'uranium metallique naturel. Or, le materiau combustible nucleaire, employe le plus souvent sous forme de barreaux de 20 a 40 mm de diametre, se trouve soumis a un ensemble de contraintes qui provoque des deformations irreversibles, le plus souvent incompatibles avec l'infrastructure du reacteur. Par consequent, le materiau combustible doit presenter a l'origine un certain nombre de qualites qu'il est necessaire de determiner. Aussi a-t-on d'abord etudie les caracteres technologiques propres a chacune des trois phases allotropiques de l'uranium-metal pur et leurs interactions sur la stabilisation du materiau constitue soit par de l'uranium coule, soit par de l'uranium traite en pile en phase {gamma}.

    Corrosion of aluminium in contact with moderating water in nuclear reactor leads to the formation of an alumina hydrosol which can have an adverse effect on the operation of the reactor. Several physical methods have been used in an attempt to counteract this effect. The method proposed here consists in the elimination of the aluminium by dissolution and subsequent fixation in the ionic form on mixed-bed ion-exchange resin. In order to do this, the parameters and the values of these parameters most favorable to the dissolution process have been determined. If the moderator is heavy water, the deuterated acid can be prepared by converting a solution in heavy water to a salt of the acid using a deuterated cationic resin. (author) [French] La corrosion de l'aluminium au contact de l'eau moderatrice des reacteurs nucleaires, donne lieu a la formation d'un hydrosol d'alumine nuisible au bon fonctionnement des reacteurs.

A cette fin on determine les parametres et leurs grandeurs favorables a cette solubilisation.

    The primary coolant of pressurised water reactors is permanently purified thanks to a device, composed of filters and the demineralizers furnished with ion exchange resins (IER), located in the chemical and volume control system (CVCS). The study of the retention mechanisms of the radio-contaminants by the IER implies, initially, to know the speciation of the primary coolant percolant through the demineralizers. Calculations of theoretical speciation of the primary coolant were carried out on the basis of known composition of the primary coolant and thanks to the use of an adapted chemical speciation code. A complementary study, dedicated to silver behaviour, considered badly extracted, suggests metallic aggregates existence generated by the radiolytic reduction of the Ag{sup +} ions. An analysis of the purification curves of the elements Ni, Fe, Co, Cr, Mn, Sb and their principal radionuclides, relating to the cold shutdown of Fessenheim 1-cycle 20 and Tricastin 2-cycle 21, was carried out, in the light of a model based on the concept of a coupling well term - source term. Then, a thermodynamic modelling of ion exchange phenomena in column was established. The formation of the permutation front and the enrichment zones planned was validated by frontal analysis experiments of synthetic fluids (mixtures of Ni(B(OH){sub 4}){sub 2}, LiB(OH){sub 4} and AgB(OH){sub 4} in medium B(OH){sub 3})), and of real fluid during the putting into service of the device mini-CVCS at the time of Tricastin 2 cold shutdown. New tools are thus proposed, opening the way with an optimised management of demineralizers and a more complete interpretation of the available experience feedback. (author)

    The fuel of PWR type reactors in usual functioning is cooled by water circulating in the primary circuit, kept at a 155 bars pressure. In the case of break in the circuit, the reactor is stopped automatically. But it is necessary to evacuate the power that continues to escape from the fuel, because of the radioactivity of products created during the reactor operating. In this aim a system called system of security injection allows to send water in the reactor core when the vapor that is releases by the primary circuit opening is condensed in the containment by the spraying system in the containment that sprays water under the containment dome. The two systems of security and spraying are supplied by a tank but when it is empty they are supplied by water recovered in the bottom of containment in sumps. The two systems operate in closed circuit and allow to evacuate the residual power. The purpose of this work is to study the risk of filters clogging that are in the sumps. (N.C.)

    The prediction of delayed strains is of crucial importance for durability and long-term serviceability of concrete structures (bridges, containment vessels of nuclear power plants, etc.). Indeed, creep and shrinkage cause cracking, losses of pre-stress and redistribution of stresses, and also, rarely, the ruin of the structure. The objective of this work is to develop numerical tools, able to predict the long-term behavior of concrete structures. Thus, a new hydro mechanical model is developed, including the description of drying, shrinkage, creep and cracking phenomena for concrete as a non-saturated porous medium. The modeling of drying shrinkage is based on an unified approach of creep and shrinkage. Basic and drying creep models are based on relevant chemo-physical mechanisms, which occur at different scales of the cement paste. The basic creep is explicitly related to the micro-diffusion of the adsorbed water between inter-hydrates and intra-hydrates and the capillary pores, and the sliding of the C-S-H gel at the nano-porosity level. The drying creep is induced by the micro-diffusion of the adsorbed water at different scales of the porosity, under the simultaneous effects of drying and mechanical loadings. Drying shrinkage is, therefore, assumed to result from the elastic and delayed response of the solid skeleton, submitted to both capillary and disjoining pressures. Furthermore, the cracking behavior of concrete is described by an orthotropic elastoplastic damage model. The coupling between all these phenomena is performed by using effective stresses which account for both external applied stresses and pore pressures. This model has been incorporated into a finite element code. The analysis of the long-term behavior is also performed on concrete specimens and prestressed concrete structures submitted to simultaneous drying and mechanical loadings. (author)

  7. Micro-pollutant exchanges at the water-bryophyta interface: monitoring of the copper concentration in nuclear power plants; Echanges de micropolluants a l`interface eau-bryophytes: suivi de la concentration en cuivre dans les centrales nucleaires

    Ciffroy, P.

    1994-12-31

    The purpose of this study is to calibrate and validate a descriptive model of the copper exchanges at the water-bryophyta interface. In theory, this model should allow calculation of the average concentrations of copper dissolved in water, using spot measurements on the bryophyta. The calibration procedure, based on mathematical use of laboratory data, demonstrated that the kinetic coefficients representing the processes of accumulation and release of the micro-pollutant by aquatic mosses, are effectively independent of the copper concentration in the water in contact with these latter, and that the reactional diagram proposed is thus well suited to representing exchanges at the water-bryophyta interface. The data collected during monitoring of the metal flows emitted by the nuclear power plants at Cattenom, Dampierre and Nogent/Seine enabled the validity of the model to be tested over a relatively large range of concentrations. The results obtained on the Cattenom and Dampierre sites would appear to be satisfactory: over the majority of control points selected, we noted good correlation between the measured and calculated concentrations of copper dissolved in water. In particular, the simulations run on periods of from 7 to 10 days show that the method is well suited to medium-term monitoring. On the other hand, the model proved inadequate for interpreting the measurements acquired during monitoring of releases from the Nogent/Seine plant set up for winter conditions. Consequently the dissolved copper estimates, calculated according to the model, considerably overestimate the actual values measured by atomic and absorption spectrometry and by voltametry. It would seem that these results can be attributed to a particular speciation of the copper on the site studied. Subsequent studies would seem necessary to confirm this point.

    In order to ensure optimal radionuclides containment, the knowledge of the actinide loading limits in nuclear waste glasses and also the comprehension of the solubilization mechanisms of these elements are essential. A first part of this manuscript deals with the study of the differences in solubility of the tri and tetravalent elements (actinides and surrogates) particularly in function of the melting temperature. The results obtained indicate that trivalent elements (La, Gd, Nd, Am, Cm) exhibit a higher solubility than tetravalent elements (Hf, Th, Pu). Consequently, it was planned to reduce plutonium at the oxidation state (III), the later being essentially tetravalent in borosilicate glasses. An innovating reduction process of multi-valent elements (cerium, plutonium) using silicon nitride has been developed in a second part of this work. Reduced plutonium-bearing glasses synthesized by Si{sub 3}N{sub 4} addition made it possible to double the plutonium solubility from 2 to 4 wt% at 1200 deg C. A structural approach to investigate the differences between tri and tetravalent elements was finally undertaken. These investigations were carried out by X-rays Absorption Spectroscopy (EXAFS) and NMR. Trivalent rare earth and actinide elements seem to behave as network modifiers while tetravalent elements rather present true intermediaries' behaviour. (author)

    The ALICE experiment is shown to be well suited for studies of exclusive final states from central diffractive reactions. The gluon-rich environment of the central system allows detailed QCD studies and searches for exotic meson states, such as glueballs, hybrids and new charmonium-like states. It would also provide a good testing ground for detailed studies of heavy quarkonia. Due to its central barrel performance, ALICE can accurately measure the low-mass central systems with good purity. The efficiency of the Forward Multiplicity Detector (FMD) and the Forward Shower Counter (FSC) system for detecting rapidity gaps is shown to be adequate for the proposed studies. With this detector arrangement, valuable new data can be obtained by tagging central diffractive processes.

  7. The Fermilab Central Computing Facility architectural model

    International Nuclear Information System (INIS)

    The goal of the current Central Computing Upgrade at Fermilab is to create a computing environment that maximizes total productivity, particularly for high energy physics analysis. The Computing Department and the Next Computer Acquisition Committee decided upon a model which includes five components: an interactive front end, a Large-Scale Scientific Computer (LSSC, a mainframe computing engine), a microprocessor farm system, a file server, and workstations. With the exception of the file server, all segments of this model are currently in production: a VAX/VMS Cluster interactive front end, an Amdahl VM computing engine, ACP farms, and (primarily) VMS workstations. This presentation will discuss the implementation of the Fermilab Central Computing Facility Architectural Model. Implications for Code Management in such a heterogeneous environment, including issues such as modularity and centrality, will be considered. Special emphasis will be placed on connectivity and communications between the front-end, LSSC, and workstations, as practiced at Fermilab. 2 figs

    In this paper we present the key aspects regarding central bank’s independence. Most economists consider that the factor which positively influences the efficiency of monetary policy measures is the high independence of the central bank. We determined that the National Bank of Romania (NBR) has a high degree of independence. NBR has both goal and instrument independence. We also consider that the hike of NBR’s independence played an important role in the significant disin...

    The literature on Currency Boards (CB) stops at the water edge in terms of dealing with the totality of the functions of a central bank. Monetary policy, and banking supervision can be "outsourced" in an open economy with substantial foreign direct investment (FDI) in the banking sector if political nationalism does not trump economic rationality. An orthodox CB renders the central banking function redundant in terms of interest rate and exchange rate determination. FDI in banking could...

  13. Towards a centralized Grid Speedometer

    International Nuclear Information System (INIS)

    Given the distributed nature of the Worldwide LHC Computing Grid and the way CPU resources are pledged and shared around the globe, Virtual Organizations (VOs) face the challenge of monitoring the use of these resources. For CMS and the operation of centralized workflows, the monitoring of how many production jobs are running and pending in the Glidein WMS production pools is very important. The Dashboard Site Status Board (SSB) provides a very flexible framework to collect, aggregate and visualize data. The CMS production monitoring team uses the SSB to define the metrics that have to be monitored and the alarms that have to be raised. During the integration of CMS production monitoring into the SSB, several enhancements to the core functionality of the SSB were required; They were implemented in a generic way, so that other VOs using the SSB can exploit them. Alongside these enhancements, there were a number of changes to the core of the SSB framework. This paper presents the details of the implementation and the advantages for current and future usage of the new features in SSB.

    2004-01-01

    Life Cycle Costing (LCC) is always a major concern in the Architecture, Engineering and Coustruction (AEC) industry. This paper presents the implementation of Building Information Modeling (BIM) technology in the development of a lifecycle cost-estimating tool. The IFC (Industry Foundation Classes) model as an interoperable building information model has been adopted as the central data repository to deliver the integrated information of building designs from CAD design systems into the lifecycle-costing database. In this paper, the coneeptions and relevant factors, which could affect the LCC estimation, have been introduced. The problems of current lCC applications have been identified as the lack of LCC data and the complexity of LCC exercises.The software application of IFC models and relevant auxiliary are depicted as a solution of the problem identified. The lifccycle costing tool is a part of the nD Modeling tool and as such is based on its integrated interface prototype toolkit and is able to holistically present an IFC model into a 3D virtual reality view, a tree-view and a list of element properties. The functions and some technical points are also detailed in the paper. Through the research, it demonstrates the potential and possibility of implementing BIM methods and techniques, particularly IFCs to enhance the computer applications in the processes of building construction and faeility management.

  6. The Naive Central Banker

    Directory of Open Access Journals (Sweden)

    Marcelo de Carvalho Griebeler

    2015-09-01

    Full Text Available There has been in some countries a trend of assigning other functions to central banks besides price stability. The most suggested function to be added to monetary authority’s obligations is to pursue economic growth or full employment. In this paper we characterize the behavior and analyse the optimal monetary policy of, what we call, a naive central banker. We describe the naive behavior as one that does face the inflation-unemployment trade-off, but it tries to minimize both variables simultaneously. Our findings, both under discretion and commitment, indicate that the naive central banker delivers lower expected inflation and inflation variance than the benchmark behavior whenever the economy is rigid enough. However, the degree of conservativeness also affects this result, such that the less conservative the naive policymaker, the more rigidity is necessary.

    2015-12-01

    The dystrophin gene involved in Duchenne and Becker muscular dystrophy is expressed in three main tissues resulting in clinical manifestations: skeletal muscle, heart and central nervous system. The 6 different existing dystrophins in the brain may play a role in the maturation and plasticity of neuronal synapses in particular by their functions in clustering and stabilization of different receptors at the post synaptic membrane. The possibility of an intellectual deficiency in Duchenne muscular dystrophy is known from the original description by Duchenne himself. Current data are in line with a constant cognitive impairment with a Gaussian curve shifted intellectual quotient (IQ) at -1 standard deviation from the standard population with an average IQ around 80. Clinical manifestations suggestive of a central nervous system involvement can affect all dystrophinopathies, including isolated central presentations without myopathic sign. The phenotypic spectrum appears broader and more subtle than non specific intellectual deficiency. The isolated or shared involvement of specific cognitive functions is possible (memory functions, executive functions, attention) with or without intellectual deficiency. Autism spectrum disorders are also among the encountered events. In clinical practice, it seems worth to ask for a measurement of serum creatine kinase (CK) in these different situations, keeping in mind that pure forms of central dystrophinopathies with a normal CK level have been recently reported.

    2016-10-01

    Reasoning, problem solving, comprehension, learning and retrieval, inhibition, switching, updating, or multitasking are often referred to as higher cognition, thought to require control processes or the use of a central executive. However, the concept of an executive controller begs the question of what is controlling the controller and so on, leading to an infinite hierarchy of executives or "homunculi". In what is now a QJEP citation classic, Baddeley [Baddeley, A. D. (1996). Exploring the central executive. Quarterly Journal of Experimental Psychology, 49A, 5-28] referred to the concept of a central executive in cognition as a "conceptual ragbag" that acted as a placeholder umbrella term for aspects of cognition that are complex, were poorly understood at the time, and most likely involve several different cognitive functions working in concert. He suggested that with systematic empirical research, advances in understanding might progress sufficiently to allow the executive concept to be "sacked". This article offers an overview of the 1996 article and of some subsequent systematic research and argues that after two decades of research, there is sufficient advance in understanding to suggest that executive control might arise from the interaction among multiple different functions in cognition that use different, but overlapping, brain networks. The article concludes that the central executive concept might now be offered a dignified retirement. PMID:26821744

  3. Implementing the chemical weapons convention

    In 1993, as the CWC ratification process was beginning, concerns arose that the complexity of integrating the CWC with national law could cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States as to how the CWC would be carried out. As a result, the author's colleagues and the author prepared the Manual for National Implementation of the Chemical Weapons Convention and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Committee of CWC Legal Experts, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Central Europe, reviewed the Manual. In February 1998, they finished the second edition of the Manual in order to update it in light of developments since the CWC entered into force on 29 April 1997. The Manual tries to increase understanding of the Convention by identifying its obligations and suggesting methods of meeting them. Education about CWC obligations and available alternatives to comply with these requirements can facilitate national response that are consistent among States Parties. Thus, the Manual offers options that can strengthen international realization of the Convention's goals if States Parties act compatibly in implementing them. Equally important, it is intended to build confidence that the legal issues raised by the Convention are finite and addressable.

Nevertheless, their implementation is a demanding job on account of numerous subjects that must acquire the specialists: nuclear, electronic and computing, fluid mechanics and sometimes... athletics when it concerns studies on the maritime sites. In spite of these numerous advantages, we must not deduce that those methods are the panacea destined to replace the other technologies.

    2014-05-01

    Full Text Available The Rivest Shamir Adleman (RSA cryptosystem, named after its creators, is one of the most popular public key cryptosystems. It is most widely used for its strong security feature and easy implementation. The RSA cryptosystem has been utilized for many e-commerce applications, various forms of authentication, and virtual private networks in any organizations. The importance of high security and faster implementations paved the way for hardware implementations of the RSA algorithm. This work consists of describing a new approach to enhance RSA security. In this paper we will enhance the security feature by introducing an advance model called Triple RSA. Although RSA has not been attacked yet, it is still prone to attacks. So to enhance its security we have implemented triple RSA just like triple DES which is extremely secure. This model provides along with confidentiality, a strong authentication, data integrity, tamper detection and non repudiation.

    Full Text Available This study identifies themes in the theoretical literature on policy implementation that can then be used to develop a research-based framework for the scholar about how qualitative research can be used to analyze policy implementation through the investigation of informal and formal communication lines. This article draws from existing scholarship to bridge the gap between policy studies and qualitative research to explore innovative ways for scholars to expand our understanding of policy implementation. The article uses the literature to propose a framework that can be used to examine policy implementation. The framework is based on the concepts of Orientation, Degree, Resources, Activity, Autonomy, Societal Values, Institutional Values, Rationale and Power Relationship.

    The Radiology Department at the University of Pennsylvania is in the process of clinically testing its PACS implementation. The PACS implementation has been built around a Vortech Image Archival and Retrieval System (IARS) with a 140-platter optical jukebox. The Vortech IARS provides archival services only. A set of software modules have been developed in-house that allow the system to function as a digital film library. The current implementation allows connectivity to a RIS (DECrad), supports the routing of images to two intensive care units, and allows image acquisition from a Du Pont FD2000 laser scanner and two GE SIGNA MR units. All process-to-process communication follows the ACR/NEMA 2.0 protocol. The proposed folder extensions to ACR/NEMA 2.0 are being utilized for sending information to the display nodes. The system has been running clinically for about three months. Details of the design, implementation, and functionality of the PACS are presented.

    Southern Asia has similar characteristics as those of central Europe during the cold war. The arguments suggesting that the nuclear dissuasion cannot work between India and Pakistan are not convincing. A deep analysis of the Indo-Pakistan 'nuclear crises' is necessary to learn lessons from the south-Asian example. This analysis suggests that both parties have learnt the dissuasion rules in an empirical way since 1990 and now have more certitudes about their options and the related risks in a bilateral nuclear environment. In particular, it appears that the line of control (LoC) is now well identified, both by Islamabad and New Delhi, as one of those 'red lines' the crossing of which would lead the conflict towards a new dimension.

    International Nuclear Information System (INIS)

    The azimuthal correlation between forward and central jets has been measured in pp collisions with the CMS detector at the LHC at the centre-of-mass energy of 7 TeV. The forward jet is required to be reconstructed in the hadronic forward calorimeter, within the pseudo-rapidity 3.2t>35 GeV. The measurement of the azimuthal angle between the jets is performed for different separations in pseudo-rapidity between the jets, with the largest separation being 7.5 units. The measurement is repeated for two subsamples of events, one in which an additional jet is required between the forward and the central jet, and one where the additional jet is vetoed. The measurement is compared to several different Monte Carlo models and tunes.

    The complete study of molten salt reactors, designed for a massive and durable nuclear energy production, must include neutronics, hydraulics and thermal effects. This coupled study, using the MCNP and Trio{sub U} codes, is undertaken in the case of the MSRE (molten salt reactor experiment) prototype. The obtained results fit very well the experiment. Their extrapolation suggests ways of improving the safety coefficients of power molten salt reactors. A second part is devoted to accelerator driven subcritical reactors, developed to incinerate radioactive waste.We propose a method to measure the prompt reactivity from the decay following a neutron pulse. It relies only on the distribution of times between generations, which is a characteristic of the reactor. This method is implemented on the results of the MUSE 4 experiment, and the obtained reactivity is accurate within 5%. (author)

    The incineration of minor actinides with a hybrid reactor (i.e. coupled with an accelerator) could reduce their radioactivity. The scientific tool used for simulations, the GEANT code implemented on a paralleled computer, has been confirmed initially on thin and thick targets and by simulation of a pressurized water reactor, a fast reactor like Superphenix, and a molten salt fast hybrid reactor `ATP`. Simulating a thermal hybrid reactor seems to indicate the non-negligible presence of neutrons which diffuse back to the accelerator. In spite of simplifications, the simulation of a molten lead fast hybrid reactor (as the CERN Fast Energy Amplifier) might indicate difficulties in the radial power distribution in the core, the life time of the window and the activated air leak risk. Finally, we propose a thermoelectric compact hybrid reactor, PRAHE - small atomic board hybrid reactor - the principle of which allows a neutron coupling between the accelerator and the reactor.

    Full Text Available This article focuses on one of the main challenges that Central Asian armies face, that is, the problem of training and formation. Having rapidly increased since 2007, Central Asian military budgets have been able to multiply the purchases of equipment and weapons from foreign partners (Russia, western countries, Israel, China, South Korea, etc.. Money is not enough, however, to get the military institution back on its feet in its most human aspect, that of formation. In fact, the teaching institutions and the training possibilities provided to conscripts and professional soldiers on contract are generally of inadequate quality and impede the overall military capacities of the Central Asian states. This article will examine the main problems of the Central Asian military institutions and will discuss the means that have been implemented by Central Asian governments to reduce the negative impact of difficulties in promoting human capital.

    One of the main goals of classical and quantum physics is to solve the many-body problem. In nuclear theory, several methods have been developed and provide accurate results. In this thesis, we remind how symmetry can be used to obtain analytical solutions of the quantum many-body problem. We emphasize that unitary Lie algebras play a crucial role in quantum mechanics and propose and implement a method to build irreducible representations of this algebra from its highest-weight state. Calculations of bosonic and fermionic spectra are performed with realistic and with random interactions. Studies with rotational invariant two-body random interactions have unveiled high degree of order (a marked statistical preference is found for ground states with angular momentum equal to zero). In the second chapter of this thesis, it is argued that the spectral properties of this kind of interaction depend on the choice of the valence space. In particular, we propose a geometrical method to predict the properties of the ground state in certain cases. We also present numerical results when the geometrical approach can not be applied. In the third chapter, we study the link between quantum chaos and nuclear spectra calculated with realistic interactions. (author)

    Trichothiodystrophy (TTD) is a rare, autosomal recessive, multisystem disorder associated with defects in nucleotide excision repair. We report a 7-year-old boy with TTD due to mutation in the XPD gene. The patient has classic features of this condition, including brittle, sulphur-deficient hair, ichthyosis, growth retardation and developmental delay. In addition, he has radiological evidence of progressive central osteosclerosis.

    International Nuclear Information System (INIS)

    Due to the commitment and participation of more than 100 professionals from site environmental coordinators, customer improvements and total quality are being incorporated into the Environmental Implementation Plan (EIP). The EIP is now a living document that communicates an overview of site environmental programs and the facility plans that are designed to protect the environment and meet changing regulatory requirements. Continuous improvement of environmental programs is enhanced through planned quarterly self-assessments during the open-quotes Reflectionsclose quotes process. Through the sharing of noteworthy practices, lessons learned, and ideas for improvement, the EIP provides a framework for environmental professionals to promote cost effective solutions and program improvements through teamwork and communication. These efforts were initiated by the Central Environmental Committee Executive Committee (CECEC) and developed and coordinated by the EIP subcommittee. The EIP revision process is the baseline for a continuous improvement cycle. Although the EIP is a Westinghouse Savannah River Company (WSRC) document, the environmental-planning process involves and will benefit all site contractors. Together, we are committed to a open-quotes Partnership in Environmental Excellence.close quotes

    The article summarises the aims and results of a three-year project conducted at the International Institute for Applied Systems Analysis called `Implementation and effectiveness of international environmental commitments` (IEC) which analysed how many environmental commitments are implemented or how intentions are put into practice. Fourteen case studies were conducted on the following issues: conservation and preservation of fauna and flora; stratospheric ozone depletion; Baltic sea pollution; trade in hazardous chemicals and pesticides; acid rain in Europe; North Sea pollution; whaling; and marine dumping of nuclear waste. The research confirmed previous findings that compliance with legally binding commitments is high. However, IEC results suggest that high compliance reflects mainly that governments make special effort to adopt only those commitments with which they can comply. The influence of those commitments is often low. In contrast, compliance with nonbinding commitments has been low, but such commitments can often have a large influence on behavior. The findings differs sharply from conventional wisdom, which maintains that the most effective international commitments are legally binding. The research suggests more attention is needed to building systems for gathering and reviewing data on implementation and for handling implementation problems. Among IEC`s contributions to policy has been to apply this finding to the design of possible non-compliance procedures within the United Nations Framework Convention on Climate Change.

    Continuous Risk Management (CM) is a software engineering practice with processes, methods, and tools for managing risk in a project. It provides a controlled environment for practical decision making, in order to assess continually what could go wrong, determine which risk are important to deal with, implement strategies to deal with those risk and assure the measure effectiveness of the implemented strategies. Continuous Risk Management provides many training workshops and courses to teach the staff how to implement risk management to their various experiments and projects. The steps of the CRM process are identification, analysis, planning, tracking, and control. These steps and the various methods and tools that go along with them, identification, and dealing with risk is clear-cut. The office that I worked in was the Risk Management Office (RMO). The RMO at NASA works hard to uphold NASA s mission of exploration and advancement of scientific knowledge and technology by defining and reducing program risk. The RMO is one of the divisions that fall under the Safety and Assurance Directorate (SAAD). I worked under Cynthia Calhoun, Flight Software Systems Engineer. My task was to develop a help screen for the Continuous Risk Management Implementation Tool (RMIT). The Risk Management Implementation Tool will be used by many NASA managers to identify, analyze, track, control, and communicate risks in their programs and projects. The RMIT will provide a means for NASA to continuously assess risks. The goals and purposes for this tool is to provide a simple means to manage risks, be used by program and project managers throughout NASA for managing risk, and to take an aggressive approach to advertise and advocate the use of RMIT at each NASA center.

    The Sihapas group contains the most prolific oil producing zones in the Central Sumatra Basin. It represents the transgressive, coarse clastic sequence deposited during the early Miocene. Some of these sandstone grade laterally into siltstones and shales of the Telisa Formation, believed to be a major source of rock for Central Sumatra oil. Recent exploratory wells drilled between the mountain front and coastal plain areas have provided more data for stratigraphic studies. These have resulted in subdivision of the lower Miocene transgressive sequence into discrete rock-stratigraphic units. The former Sihapas Formation has subsequently been elevated to group rank and now consists of several formations with the Duri Formation as the uppermost sand unit. This study covers Caltex's areas of operation, which includes the area between the Kampar River of the south, the Barumum River to the north, the Malacca Straits to the east, and the Barisan Mt. to the west. A basic map shows the regional scene, while a stratigraphic chart shows the lithology.

    Using the properties of radioactive matter to generate energy without CO{sub 2} emission represents a suitable answer to the increasing problem of energy and environment constraints. The counterpart of these advantages is the irradiation risk, which is taken into consideration by a strict respect of safety rules by nuclear operators and by the implementation of a high quality safety culture. This press kit presents the evolutions to come in the domain of reactor technology according to the conclusions of the Generation 4 international forum launched in the year 2000. These evolutions give a clear preference to fast neutron technologies, and in a lesser extend to thermal neutron technologies. These choices represent an opportunity to rediscover technologies already tested at the prototype stage (sodium-cooled FBRs for instance) and to develop alternative and new technologies for new applications (gas-cooled FBRs for high temperature cogeneration, very-high temperature reactors for hydrogen or synthetic fuels generation). The overall research program on fast neutron reactors aims at demonstrating the industrial perspectives of separation-transmutation processes and at developing a new generation of fast reactors, competitive with the water reactors technology, and fulfilling the safety, non-proliferation and waste management requirements. A new technological platform devoted to sustainable nuclear energy was launched on September 21, 2007 at Brussels (Belgium) and aims at controlling the security of energy supplies in member states, ensuring a sustainable development, and improving the competitiveness of the offer. The French institute of radiation protection and nuclear safety (IRSN) is in charge of the national control of nuclear safety in France.

    Centrality has revealed crucial for understanding the structural order of complex relational networks. Centrality is also relevant for various spatial factors affecting human life and behaviors in cities. We present a comprehensive study of centrality distributions over geographic networks of urban streets. Four different measures of centrality, namely closeness, betweenness, straightness and information, are compared over eighteen 1-square-mile samples of different world cities. Samples are represented by primal geographic graphs, i.e. valued graphs defined by metric rather than topologic distance where intersections are turned into nodes and streets into edges. The spatial behavior of centrality indexes over the networks is investigated graphically by means of colour-coded maps. The results indicate that a spatial analysis, that we term Multiple Centrality Assessment(MCA), grounded not a single but on a set of different centrality indices, allows an extended comprehension of the city structure, nicely captu...

  6. UA2 central calorimeter

    CERN Multimedia

    The UA2 central calorimeter measured the energy of individual particles created in proton-antiproton collisions. Accurate calibration allowed the W and Z masses to be measured with a precision of about 1%. The calorimeter had 24 slices like this one, each weighing 4 tons. The slices were arranged like orange segments around the collision point. Incoming particles produced showers of secondary particles in the layers of heavy material. These showers passed through the layers of plastic scintillator, generating light which was taken by light guides (green) to the data collection electronics. The amount of light was proportional to the energy of the original particle. The inner 23 cm of lead and plastic sandwiches measured electrons and photons; the outer 80 cm of iron and plastic sandwiches measured strongly interacting hadrons. The detector was calibrated by injecting light through optical fibres or by placing a radioactive source in the tube on the bottom edge.

  7. UA1 central detector

    CERN Multimedia

    The UA1 central detector was crucial to understanding the complex topology of proton-antiproton events. It played a most important role in identifying a handful of Ws and Zs among billions of collisions. The detector was a 6-chamber cylindrical assembly 5.8 m long and 2.3 m in diameter, the largest imaging drift chamber of its day. It recorded the tracks of charged particles curving in a 0.7 Tesla magnetic field, measuring their momentum, the sign of their electric charge and their rate of energy loss (dE/dx). Atoms in the argon-ethane gas mixture filling the chambers were ionised by the passage of charged particles. The electrons which were released drifted along an electric field shaped by field wires and were collected on sense wires. The geometrical arrangement of the 17000 field wires and 6125 sense wires allowed a spectacular 3-D interactive display of reconstructed physics events to be produced.

    2016-02-01

    Perform Achieve Trade (PAT) is a market-based incentive mechanism to promote energy efficiency. The purpose of this work is to address the challenges inherent to inconsistent representation of business processes, and interoperability issues in PAT like cap-and-trade mechanisms especially when scaled. Studies by various agencies have highlighted that as the mechanism evolves including more industrial sectors and industries in its ambit, implementation will become more challenging. This paper analyses the major needs of PAT (namely tracking, monitoring, auditing & verifying energy-saving reports, and providing technical support & guidance to stakeholders); and how the aforesaid reasons affect them. Though current technologies can handle these challenges to an extent, standardization activities for implementation have been scanty for PAT and this work attempts to evolve them. The inconsistent modification of business processes, rules, and procedures across stakeholders, and interoperability among heterogeneous systems are addressed. This paper proposes the adoption of specifically two standards into PAT, namely Business Process Model and Notation for maintaining consistency in business process modelling, and Common Information Model (IEC 61970, 61968, 62325 combined) for information exchange. Detailed architecture and organization of these adoptions are reported. The work can be used by PAT implementing agencies, stakeholders, and standardization bodies.

This paper will discuss the Python language implementation of this API and some of the capabilities that this implementation provides for data storage and retrieval using the MDSplus system. We have implemented a new MDSplus Python module which exposes the MDSplus objects features to the language. The internal MDSplus programming language, TDI, has also been enhanced to be able to invoke Python commands from the TDI language. Now that Python is aware of the complex data structures in MDSplus such as Signals, the language becomes a very good candidate for applications ranging from data acquisition device support to analysis and visualization. This document is composed of an abstract followed by the presentation slides. (authors)

  11. Expectations from implementers

    International Nuclear Information System (INIS)

    Enrique Biurrun (DBE) presented the expectations from the implementer. He explained that the implementer needs a framework to successfully develop a repository which means the definition of requirements and guidance (for repository system development, analysis, licences, etc.) as well as the decision-making process (stepwise approach, roles of different players, etc.). He also needs a reasonable stability of the regulatory system. The regulatory framework should be developed in a clear, reasonable and consistent manner. In the context of the long duration of the project (100 years) there will be technological progress. In that context E. Biurrun asked what is the meaning of best practice. How can one deal with judgmental issues in a step-wise approach? Regulatory criteria and guidance must deal with the repository system for which an iterative process is necessary where dialogue is needed with the regulator despite the need to maintain his independence. The safety case, which is a periodic documentation of the status of the project, must provide a synthesis of the underlying scientific understanding and evidence and becomes part of the design process through feedback. E. Biurrun pointed out that safety is not calculated or assessed, but designed and built into the repository system (by geological and engineered barriers). He stressed the importance of the operational aspects since the implementer has to build and operate the repository safely. He asked the question: is it 'Ethical' to buy 'peace of mind' of some stakeholders with casualties of the implementer's staff because of mining accidents if the repository is left open during a phase of reversibility. The implementer needs dependable criteria, legal security and investment security. He interpreted the 'Precautionary principle' as meaning 'do it now'. Long-lasting solutions are very uncertain. Will we heave the money and the technology to do it later? He made some reflections regarding the ethical need to

  12. Central system of Interlock of ITER, high integrity architecture

    International Nuclear Information System (INIS)

    The CIS (Central Interlock System), along with the CODAC system and CSS (Central Safety System), form the central I and C systems of ITER. The CIS is responsible for implementing the core functions of protection (Central Interlock Functions) through different systems of plant (Plant Systems) within the overall strategy of investment protection for ITER. IBERDROLA supports engineering to define and develop the control architecture of CIS according to the stringent requirements of integrity, availability and response time. For functions with response times of the order of half a second is selected PLC High availability of industrial range. However, due to the nature of the machine itself, certain functions must be able to act under the millisecond, so it has had to develop a solution based on FPGA (Field Programmable Gate Array) capable of meeting the requirements architecture. In this article CIS architecture is described, as well as the process for the development and validation of the selected platforms. (Author)

  16. Implementing the ICPD's message.

    Jain, A

    1995-01-01

    The International Conference on Population and Development held in Cairo in September 1994 recognized the need for reducing unwanted fertility and promoting smaller families within reproductive health services along with improving women's equality in education, health, and economic opportunity. The implementation of the main message would require an ideological transformation both for the population and for the development establishments. The implementation of a broadened population policy must incorporate the reduction of gender disparities as the primary goal. The problem is that the UNFPA has no influence over resources allocated to child health, female education, economic opportunities for women, or empowerment of women. Reproductive health and family planning programs should be integrated within the broader health services; however, reproductive health may not receive the desired high priority. Family planning programs are also expected to solve two problems: to improve individual well-being and to reduce overall fertility. Managers are likely to implement the reproductive health approach if it is a cost-effective way of reducing total fertility. However, no evidence exists to show that treating reproductive tract infections is a cost-effective way of reducing fertility. The primary objective of family planning programs should be empowerment of individuals to achieve their own reproductive goals in a healthful manner. Fertility reduction should be linked to fertility reduction by focusing on unwanted childbirth and to reproductive health services. The redesign of contraceptive services from a reproductive health perspective would deal with the contraindications of each method by developing standards for screening and focusing as well on the diagnosis and treatment of these conditions. The suggested role of the population sector in the tasks of development and family planning lies in promoting the main message to a wider national and international audience

  17. LSST operation simulator implementation

    Delgado, Francisco; Cook, Kem; Miller, Michelle; Allsman, Robyn; Pierfederici, Francesco

    2006-06-01

    We have developed an operation simulator for the Large Synoptic Survey Telescope (LSST) that is an implementation in Python language using the SimPy extension, with a modular and object-oriented design. The main components include a telescope model, a sky model, a weather database for 3 sites, a scheduler and multiple observing proposals. All the proposals derive from a parent class which is fully configurable through about 75 parameters to implement a specific science survey. These parameters control the target selection region, the composition of the sequence of observations for each field, the timing restrictions and filter selection criteria of each observation, the lunation handling, seeing limits, etc. The current implemented proposals include Weak Lensing, Near Earth Asteroids, Supernova and Kuiper Belt Objects. The telescope model computes the slew time delay from the current position to any given target position, using a complete kinematic model for the mount, dome and rotator, as well as optics alignment corrections. The model is fully configurable through about 50 parameters. The scheduler module combines the information received from the proposals and the telescope model for selecting the best target at each moment, promoting targets that fulfill multiple surveys and storing all the simulator activities in a MySQL database for further analysis of the run. This scheduler is also configurable; for example, balancing the weight of the slew time delay in selecting the next field to observe. This simulator has been very useful in clarifying some of the technical and scientific capabilities of the LSST design, and gives a good baseline for a future observation scheduler.

    A number of different possible programs for nuclear power stations of various types are presented in this survey. These programs are established in relation to the use of uranium and thorium in amounts similar to those that shall probably be produced in France during the next fifteen years. As it is possible to draw plans for nuclear power stations in which several processes exist simultaneously, an unlimited number of variations being thinkable, this survey is limited to successive analysis of the results obtained by use of only one of each of the following three systems: - system natural uranium-graphite, - system natural uranium-heavy water, -system enriched uranium-pressurised light water. All schemes are considered as assemblages of these three simple systems. The effects of plutonium recycling are also considered for each system. The electric power installed and the capacity of stations situated up-stream and down-stream have been calculated by this method and an attempt has been made to establish the sum to be invested during the fifteen years necessary for the launching of the programs scheduled. A table of timing for the investments groups the results obtained. Considering the fact that French availabilities in capital shall not be unlimited during the coming years, this way of presenting the results seems to be interesting. (author)Fren.

    2009-06-01

    Deaf patients with severe sensory hearing loss can benefit from a cochlear implant (CI), which stimulates the auditory nerve fibers. However, patients who do not have an intact auditory nerve cannot benefit from a CI. The majority of these patients are neurofibromatosis type 2 (NF2) patients who developed neural deafness due to growth or surgical removal of a bilateral acoustic neuroma. The only current solution is the auditory brainstem implant (ABI), which stimulates the surface of the cochlear nucleus in the brainstem. Although the ABI provides improvement in environmental awareness and lip-reading capabilities, only a few NF2 patients have achieved some limited open set speech perception. In the search for alternative procedures our research group in collaboration with Cochlear Ltd. (Australia) developed a human prototype auditory midbrain implant (AMI), which is designed to electrically stimulate the inferior colliculus (IC). The IC has the potential as a new target for an auditory prosthesis as it provides access to neural projections necessary for speech perception as well as a systematic map of spectral information. In this paper the present status of research and development in the field of central auditory prostheses is presented with respect to technology, surgical technique and hearing results as well as the background concepts of ABI and AMI.

  4. CENTRAL EUROPE: Role models

    International Nuclear Information System (INIS)

    Hungary is one of the newcomers to the CERN fold, having joined in 1992. The country's contributions are naturally in line with its slender resources and are not as immediately visible as those of the major Western European Member States. However the approach used and its consequent successes provide a good role model for a smaller nation in an international research environment. This was reflected on 24 September at a meeting of the European Committee for Future Accelerators (ECFA) convened in Budapest, continuing an ECFA tradition of holding meetings in national centres to learn more about the physics programmes of different countries. This tradition started with visits to major West European Centres, but last year ECFA held a meeting in Warsaw, its first in a central European country. By far the largest Hungarian population centre, Budapest is also a hub for national research in this sector, with university centres and the KFKI Research Institute for Particle and Nuclear Physics of the National Academy of Sciences. However important research work is also carried out in the eastern city of Debrecen. Hungarians look back to the classic investigations of Eotvos early this century as the starting point of their national tradition in fundamental physics. (In the mid-80s, these experiments briefly came back into vogue when there was a suggestion of an additional 'fifth force' contribution to nuclear masses.)

    2011-01-14

    Cleanup of the Hanford Site is a complex and challenging undertaking. The U.S. Department of Energy (DOE) has developed a comprehensive vision for completing Hanford's cleanup mission including transition to post-cleanup activities. This vision includes 3 principle components of cleanup: the {approx}200 square miles ofland adjacent to the Columbia River, known as the River Corridor; the 75 square miles of land in the center of the Hanford Site, where the majority of the reprocessing and waste management activities have occurred, known as the Central Plateau; and the stored reprocessing wastes in the Central Plateau, the Tank Wastes. Cleanup of the River Corridor is well underway and is progressing towards completion of most cleanup actions by 2015. Tank waste cleanup is progressing on a longer schedule due to the complexity of the mission, with construction of the largest nuclear construction project in the United States, the Waste Treatment Plant, over 50% complete. With the progress on the River Corridor and Tank Waste, it is time to place increased emphasis on moving forward with cleanup of the Central Plateau. Cleanup of the Hanford Site has been proceeding under a framework defmed in the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement). In early 2009, the DOE, the State of Washington Department of Ecology, and the U.S. Environmental Protection Agency signed an Agreement in Principle in which the parties recognized the need to develop a more comprehensive strategy for cleanup of the Central Plateau. DOE agreed to develop a Central Plateau Cleanup Completion Strategy as a starting point for discussions. This DOE Strategy was the basis for negotiations between the Parties, discussions with the State of Oregon, the Hanford Advisory Board, and other Stakeholder groups (including open public meetings), and consultation with the Tribal Nations. The change packages to incorporate the Central Plateau Cleanup Completion Strategy were

    Solutions of stable free radicals of the nitroxide type have been studied as a function of temperature. In the plastic or globular state, the cyclohexane molecules have rapid rotational and diffusional movements. They transmit this movement to dissolved free radicals. Conversely, measurements by electron spin resonance of the absolute movement of the radicals, and by electron nuclear double resonance of their movement relative to the cyclohexane molecules give very precise methods for local analyses of the movement present in the cyclohexane matrix. The principle of these techniques makes up the 'radical probe method'. (author) [French] Des solutions de radicaux libres stables, du type nitroxyde dans le cyclohexane ont ete etudiees, en fonction de la temperature. Les molecules de cyclohexane, dans l'etat plastique ou globulaire, sont animees de mouvements rapides de rotation sur elles-memes et de diffusion. Elles transmettent leur mobilite aux radicaux libres dissous. Reciproquement, la mesure du mouvement absolu des radicaux, a l'aide de la resonance paramagnetique electronique, et celle du mouvement relatif des radicaux et des molecules de cyclohexane par double resonance electronique-nucleaire, constituent des methodes tres precises pour analyser localement les mouvements presents dans la matrice de cyclohexane.

    Kiley, M A; King, M; Burns, R J

    1999-03-01

    Central pontine myelinolysis (CPM) was initially associated with alcoholism. Subsequently other factors, including rapid reversal of hyponatraemia and extreme serum hypoosmolality associated with severe burns, have been identified as other important factors in its pathogenesis. Extra-pontine lesions have also been described. CPM may be found at autopsy, either having been overlooked during life or as an incidental finding. Its precise incidence is not known but the ability to diagnose it during life has been helped by modern neuroimaging, particularly magnetic resonance imaging (MRI) of the brain stem. In the past the prognosis for CPM was thought to be invariably fatal. It is clear now that with the greater general awareness of the disorder and the ability to diagnose it during life that some degree of recovery is possible. However, the number who do recover and the degree of recovery is not known. We report a 40-year-old man who developed CPM presenting with quadriparesis and inability to speak and swallow. There were risk factors for CPM and the diagnosis was confirmed by MRI scanning. He made a complete recovery although he remains ataxic. We are reporting this case as we believe it is important to make clinicians aware of the potential for recovery of CPM. While no specific treatment has been shown to influence the degree and rate of recovery of the demyelination, the fact that the quadriplegia and bulbar paralysis can recover fully is of considerable importance. In particular, it means that when the diagnosis is made, complete and vigorous nursing and medical care is warranted. PMID:18639140

    Children who appear healthy, even if they have one or more recognized cardiovascular risk factors, do not generally have outcomes of cardiovascular or other vascular disease during childhood. Historically, pediatric medicine has not aggressively screened for or treated cardiovascular risk factors in otherwise healthy children. However, studies such as the P-Day Study (Pathobiological Determinants of Atherosclerosis in Youth), and the Bogalusa Heart Study, indicate that healthy children at remarkably young ages can have evidence of significant atherosclerosis. With the increasing prevalence of pediatric obesity, can we expect more health problems related to the consequences of pediatric dyslipidemia, hypertriglyceridemia, and atherosclerosis in the future? For many years, medications have been available and used in adult populations to treat dyslipidemia. In recent years, reports of short-term safety of some of these medications in children have been published. However, none of these studies have detailed long-term follow-up, and therefore none have described potential late side-effects of early cholesterol-lowering therapy, or potential benefits in terms of reduction of or delay in cardiovascular or other vascular end-points. In 2007, the American Heart Association published a scientific statement on the use of cholesterol-lowering therapy in pediatric patients. In this review paper, we discuss some of the current literature on cholesterol-lowering therapy in children, including the statins that are currently available for use in children, and some of the cautions with using these and other cholesterol-lowering medications. A central tenet of this review is that medications are not a substitute for dietary and lifestyle interventions, and that even in children on cholesterol-lowering medications, physicians should take every opportunity to encourage children and their parents to make healthy diet and lifestyle choices.

  14. Central nervous system tumors

    International Nuclear Information System (INIS)

    Central nervous system (CNS) tumors are relatively common in veterinary medicine, with most diagnoses occurring in the canine and feline species. Numerous tumor types from various cells or origins have been identified with the most common tumors being meningiomas and glial cell tumors. Radiation therapy is often used as an aid to control the clinical signs associated with these neoplasms. In general, these tumors have a very low metastatic potential, such that local control offers substantial benefit. Experience in veterinary radiation oncology would indicate that many patients benefit from radiation treatment. Current practice indicates the need for computed tomography or magnetic resonance imaging studies. These highly beneficial studies are used for diagnosis, treatment planning, and to monitor treatment response. Improvements in treatment planning and radiation delivered to the tumor, while sparing the normal tissues, should improve local control and decrease potential radiation related problems to the CNS. When possible, multiple fractions of 3 Gy or less should be used. The tolerance dose to the normal tissue with this fractionation schedule is 50 to 55 Gy. The most common and serious complications of radiation for CNS tumors is delayed radiation myelopathy and necrosis. Medical management of the patient during radiation therapy requires careful attention to anesthetic protocols, and medications to reduce intracranial pressure that is often elevated in these patients. Canine brain tumors have served as an experimental model to test numerous new treatments. Increased availability of advanced imaging modalities has spawned increased detection of these neoplasms. Early detection of these tumors with appropriate aggressive therapy should prove beneficial to many patients

    1996-08-01

    Full Text Available The world has been challenged by the AIDS epidemic for 15 years. In 1985, the U.S. Department of Health and Human Services, Centers for Disease Control, allocated funds to all state departments of education to assist schools in the development of AIDS education policies and programs. Yet, these policies do not ensure that all students receive effective AIDS education. On September 21, 1991, the Arizona Legislature passed Senate Bill 1396, which requires public schools to annually provide AIDS education in grades K-12. The bill was rescinded in 1995. With prohibitive curriculum guidelines, limited teacher training opportunities and tremendous instructional demands, this educational policy was implemented in disparate forms. By examining the perspectives of the Arizona educators (representing three school districts, this qualitative study reveals how teachers ultimately controlled the delivery and nature of AIDS instruction based upon personal values, views of teacher roles, and their interpretation of the mandate itself.

    Software Defined Radio makes wireless communications easier, more efficient, and more reliable. This book bridges the gap between academic research and practical implementation. When beginning a project, practicing engineers, technical managers, and graduate students can save countless hours by considering the concepts presented in these pages. The author covers the myriad options and trade-offs available when selecting an appropriate hardware architecture. As demonstrated here, the choice between hardware- and software-centric architecture can mean the difference between meeting an aggressive schedule and bogging down in endless design iterations. Because of the author’s experience overseeing dozens of failed and successful developments, he is able to present many real-life examples. Some of the key concepts covered are: Choosing the right architecture for the market – laboratory, military, or commercial Hardware platforms – FPGAs, GPPs, specialized and hybrid devices Standardization efforts to ens...

  2. Implementing a hydrogen economy

    2003-09-01

    In recent years, months, weeks, and even days, it has become increasingly clear that hydrogen as an energy carrier is ‘in’ and carbonaceous fuels are ‘out’1. The hydrogen economy is coming, with the impetus to transform our fossil energy-based society, which inevitably will cease to exist, into a renewable energy-based one2. However, this transformation will not occur overnight. It may take several decades to realize a hydrogen economy. In the meantime, research and development is necessary to ensure that the implementation of the hydrogen economy is completely seamless, with essentially no disruption of the day-to-day activities of the global economy. The world has taken on a monumental, but not insurmountable, task of transforming from carbonaceous to renewable fuels, with clean burning, carbon dioxide-free hydrogen as the logical choice.

    Central neural circuits orchestrate the behavioral and autonomic repertoire that maintains body temperature during environmental temperature challenges and alters body temperature during the inflammatory response and behavioral states and in response to declining energy homeostasis. This review summarizes the central nervous system circuit mechanisms controlling the principal thermoeffectors for body temperature regulation: cutaneous vasoconstriction regulating heat loss and shivering and brown adipose tissue for thermogenesis. The activation of these thermoeffectors is regulated by parallel but distinct efferent pathways within the central nervous system that share a common peripheral thermal sensory input. The model for the neural circuit mechanism underlying central thermoregulatory control provides a useful platform for further understanding of the functional organization of central thermoregulation, for elucidating the hypothalamic circuitry and neurotransmitters involved in body temperature regulation, and for the discovery of novel therapeutic approaches to modulating body temperature and energy homeostasis.

    In this paper, we consider the flat central configurations of bodies using the characteristic set method. We completely solve two special cases of four planets, namely,the square and the rhombus. For the square case, we obtain that a square is a central configuration only in the case where the masses are equal and there exactly are two different square central configurations determined by the mass and the angular velocity; for the rhombus case, we obtain that if a rhombus is a central configuration, then the masses of the diagonal vertices must be equal. Furthermore, there are two or three or four different rhombus central configurations determined by the masses and the angular velocity.

    high-power reactors. (author) [French] Les chambres d'ionisation sont actuellement les detecteurs les mieux adaptes au controle des reacteurs nucleaires par des mesures neutroniques. Nous avons cru bon de rappeler quelques generalites concernant la dynamique des reacteurs, les differents procedes de detection des neutrons, le fonctionnement des chambres d'ionisation et les methodes de mesure utilisees. Notre contribution aux techniques de controle des reacteurs consiste d'une part en une tentative de synthese des facteurs intervenant dans le fonctionnement des chambres d'ionisation, l'etude de ces facteurs, et d'autre part l'elaboration de chambres d'ionisation a fission et a bore permettant de suivre la marche d'un reacteur du demarrage jusqu'a la puissance maximale. Dans le domaine des chambres a fission, nous avons en particulier ameliore les techniques de depot d'oxyde d'uranium sur l'aluminium et realise la mise au point de depots par electrolyse sur d'autres metaux: acier inoxydable, cuivre, molybdene, nickel, tantale, titane, kovar, tungstene et beryllium. Nous avons elabore plusieurs types de chambres a fission servant au demarrage des reacteurs: un type de performances moyennes actuellement utilise dans les piles francaises un type a haute sensibilite un type a haute temperature qui a fonctionne jusqu'a 600 deg. C. En ce qui concerne les chambres a bore, nous avons etudie les perturbations apportees dans les mesures par l'exposition des chambres a d'importants flux de neutrons et a un rayonnement {gamma} intense. Cette exposition produit une modification des proprietes des materiaux constitutifs et la production dans les chambres d'un bruit de fond qui peut gener considerablement les mesures neutroniques. Nous avons montre que la technique de compensation permettait de limiter l'importance de ce bruit de fond et d'augmenter ainsi la plage de fonctionnement des

Study of transfers and their interactions with self-healing in the cracks to increase the service life of infrastructures (bridges, nuclear centrals); Etude des transferts et de leurs interactions avec la cicatrisation dans les fissures pour prolonger la duree de service des infrastructures (ponts, centrales nucleaires)

    Concrete structures are frequently cracked by the action of different types of physicochemical mechanisms (external loads, restrained shrinkage, internal expansion). Cracks could impair the durability of concrete structures by creating preferential paths for the penetration of various types of potentially aggressive agents (liquids, gases, and ions). The aim of this thesis is to study transport properties in mechanically induced cracks. The first objective of the study is to better understand the potential effect of critical crack opening and self-healing. Cracks were generated in an inert material (brick) and in old mortar samples of 28 days and 2 years of age. A mechanical expansive core was used to generate cracks of constant width across the thickness of the sample. For the brick material, results show that a mechanical interaction between the fracture surfaces (critical crack opening) can affect the chloride-diffusion process along a crack path. A critical crack opening was also found for mortar samples. The age at which cracks were generated is also an important parameter. Self-healing was found to be more important in young mortars (28 days). The second objective of this thesis is the prediction of airflow in cracked cementitious material samples. A model proposed by Rizkalla et al. was evaluated through the experimental measurement of the flow coefficient n and the friction coefficient k. A simplified model was proposed to predict airflow through a crack for laminar type flow. The third research objective is to study the effect of self-healing on airflow through cracked mortar samples stored in a 100% relative humidity environment. Results show that self-healing mainly occurs during the first two months of storage. SEM analysis of fracture surfaces shows the formation of self-healing products such as calcite, C-S-H, and ettringite. (author)

    This radar image shows the dramatic landscape in the Phang Hoei Range of north central Thailand, about 40 kilometers (25 miles) northeast of the city of Lom Sak. The plateau, shown in green to the left of center, is the area of Phu Kradung National Park. This plateau is a remnant of a once larger plateau, another portion of which is seen along the right side of the image. The plateaus have been dissected by water erosion over thousands of years. Forest areas appear green on the image; agricultural areas and settlements appear as red and blue. North is toward the lower right. The area shown is 38 by 50 kilometers (24 by 31 miles) and is centered at 16.96 degrees north latitude, 101.67 degrees east longitude. Colors are assigned to different radar frequencies and polarizations as follows: red is L-band horizontally transmitted and horizontally received; green is L-band horizontally transmitted and vertically received; blue is C-band horizontally transmitted and vertically received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture (SIR-C/X-SAR) imaging radar on October 3, 1994, when it flew aboard the space shuttle Endeavour. SIR-C/X-SAR is a joint mission of the U.S./German and Italian space agencies.Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA

  14. Radioactivity in Zircon from Jos, Central Nigeria

    International Nuclear Information System (INIS)

    Mining and processing of zircon along with other minerals, generally for export purposes, have been taking place in Jos, central Nigeria, for several decades. Over the years, there has been increasing concern about the radiological impact resulting from these activities. A previous assessment in the vicinity of processing areas reported an annual dose of 50 mSv which by far exceeds the 1 mSv dose limit for members of the public. In the study, the activity concentrations of 238U and 232Th in 28 samples of zircon from Jos were determined using neutron activation analysis. The results gave concentrations of 466 μg/g (5.75 Bq/g) for 238U and 7054 μg/g (28.62 Bq/g) for 232Th. These results complement the results of earlier assessments and may assist in the proper management of these activities and the choice and implementation of appropriate protective measures. (author)

    Keul, Alexander G.; Sioutas, Michalis V.; Szilagyi, Wade

    The North American waterspout forecasting methodology by Szilagyi is applied on a sample of 110 waterspout events for the years 2002-2006 over the Central-Eastern Mediterranean (the Adriatic, Ionian and Aegean Sea). First, the geographical distribution and frequency of the phenomena are shown. Four synoptic types of waterspout-prone circulation patterns are considered. For the Adriatic cases, five thermodynamic indices (KI, TT, SWEAT, CAPE, BRN) are used as possible predictors. The testing of the Szilagyi Waterspout Nomogram and Index (SWI), developed for the Great Lakes region, was favorable for the Mediterranean case data, validating its use as a prognostic tool. Results were presented and discussed at the 4th European Conference on Severe Storms ECSS at Trieste. Meteorologists should standardize and evaluate waterspout prognostic tools and implement a visual interface to improve the service for relevant user groups.

    The authors propose a report on the various situations of people who had to be evacuated after the Fukushima accident. Along with examples of people who left their homes with taking with them a single object, the authors describe and comment how this evacuation occurred, the problems faced by the authorities for refugee reception and accommodation. This evacuation has been either organised or spontaneous. Hospitals had to be evacuated as well. Then, local authorities faced food shortage. Some animals have been saved, other starved to death. Dead animals are covered with lime. Dead bodies are decontaminated before being given back to families. Tests are regularly performed to assess people contamination. A second article discussed the bad news concerning the different Fukushima reactors with their melted cores. The geophysical aspects of the earthquake are evoked in a last article

    The author reports the history of the Manhattan project which was launched in 1942 with the objective of building an A bomb at any price and as soon as possible. This lead to the fabrication of two types of bomb, one using uranium in gun mode, and the other using plutonium in implosion mode. The author recalls the creation of different scientific and nuclear institutions, the development of several installations (Los Alamos, Hanford, Oak Ridge). He outlines the project secrecy (President Truman did not know anything about it when he became president), and recalls the final tests, the bombing of Hiroshima and Nagasaki, and the last moment of the Manhattan Project after the end of the war. In conclusion, he notices that this nuclear era allowed a direct confrontation to be avoided despite the several crises which occurred during about two decades after the war

    For a long time, a small group of big powers has been the only holder of nuclear weapons (US, USSR, Great Britain, France and China). Since then, new weapons have come out on the geopolitical scene: Israel, India, Pakistan, and some others remain uncertain and generate a worrying atmosphere (North Korea, Iran..). But what is the real risk with nuclear proliferation? Should we dread about it? Is nuclear terrorism a real threat? What are the political stakes of nuclear weapons? Is disarmament a real solution? These are some of the questions that the author answers in a precise and clear manner in this book. Contents: 1 - from monopoly to proliferation: who owns nuclear weapons today, why is it so coveted, is it easy to make one?; 2 - the newcomers: what do we really know about the Iranian nuclear programme, Iran and North Korea: between negotiation and confrontation; 3 - international control and regulation: do we have reliable information, how do we know what we know, Iraq: was there a 'lie' somewhere, who are the states who have renounced nuclear weapons?; 4 - the future: is there still a nuclear warfare risk, what if Pakistani weapons fall into islamic hands, is nuclear terrorism a fantasy or a real risk?

    After many years of low profile business in the USA, MRI is back. Improvements are focused on high field magnets and on low field magnets. The former, are dedicated to high quality imaging. The new scanners are more and more efficient because of the spreading use of real time imaging. They can do now, procedures that just could not be imagined some years ago. Vascular imaging is done routinely. Abdominal imaging in apnea of EPI, perfusion and diffusion imaging, and, last not least, all the field of functional imaging are on the verge of coming out. The new magnets unveiled in 1997 are lighter, smaller, more, user friendly, less impressive for patients subject to claustrophobia. They also need less helium to operate and less space to be sited. The latter, are dedicated to interventional procedures. The new magnets are wide opened and a lot of companies show off. Though Picker unveiled a new light superconductive 0.5 Tesla magnet, it seems that this kind of machines are about to disappear. No significant progress was noticed in the field of dedicated MRI devices. Some features can be highlighted: the new Siemens short bore and its table integrates the Panoramic Array Coil Concept. It will allow simultaneous scanning with up to four coils; the excellent homogeneity of the new Picker magnet that will allow spectroscopy at 1 Tesla; the twin gradients of the Elscint Prisma that will open the field of microscopy MRI; the Philips `floppy gradients` that could speed up 4 or 6 times, the time needed for imaging; some new sequences sensitive to temperature are studied as WIP; a lot of work is achieved on 3 or 4 Tesla scanners etc. (author)

  1. Betweenness centrality profiles in trees

    CERN Document Server

    Fish, Benjamin; Turan, Gyorgy

    2016-01-01

    Betweenness centrality of a vertex in a graph measures the fraction of shortest paths going through the vertex. This is a basic notion for determining the importance of a vertex in a network. The k-betweenness centrality of a vertex is defined similarly, but only considers shortest paths of length at most k. The sequence of k-betweenness centralities for all possible values of k forms the betweenness centrality profile of a vertex. We study properties of betweenness centrality profiles in trees. We show that for scale-free random trees, for fixed k, the expectation of k-betweenness centrality strictly decreases as the index of the vertex increases. We also analyze worst-case properties of profiles in terms of the distance of profiles from being monotone, and the number of times pairs of profiles can cross. This is related to whether k-betweenness centrality, for small values of k, may be used instead of having to consider all shortest paths. Bounds are given that are optimal in order of magnitude. We also pre...

  5. EPA speeds technology implementation

    International Nuclear Information System (INIS)

    Common barriers block the use of innovative remediation technologies. The Innovative Treatment Remediation Demonstration (ITRD) Program at the US Department of Energy's (DOE's) Sandia National Laboratories was initiated in 1993 in cooperation with the US Environmental Protection Agency's (EPA's) Technology Innovation Office in an attempt to reduce these barriers and accelerate the implementation of innovative remediation technologies. The innovative technologies considered for evaluation by the ITRD program lack the cost and performance information that would otherwise permit their full consideration as remedial alternatives. These technologies have often shown promise in pilot-scale applications but have limited full-scale data. Some examples in this category include: bioremediation, in situ dynamic stripping, soil washing and soil flushing, solvent and surfactant extraction and chemical treatment, in situ passive treatment, and advanced physical separation techniques. Currently, three ITRD projects are under way. ITRD sites are generally small, and most are characterized sites already scheduled for remediation. Thus, each project can be initiated quickly; additional program costs are minimized; and overall site remediation is accelerated. ITRD projects tend to target sites with typical soil and groundwater contamination problems. Contaminants at such sites include chlorinated solvents and petroleum products; pesticides, polychlorinated biphenyls (PCBs), and dioxins; heavy metals; explosives; and complex or multiconstituent contamination. The paper describes the activities at these three projects located at Pinellas, Mound Laboratory, and Fernald

    TRUPACT-1, the TRansUranic PACkage Transporter is a packaging designed to transport defense contact handled transuranic (CH-TRU) waste from generating and interim TRU waste storage facilities to the Waste Isolation Pilot Plant (WIPP). Prior to fabrication and procurement of a full fleet, an initial design (TRUPACT-1) will be introduced to the defense TRU waste complex through use in an operational prototype fleet which will consist of Units 1, 2, and 3. In an effort to provide a relatively smooth introduction of the TRUPACT-1, the TRUPACT Technical Team (TTT) has developed the following implementation plan. The plan provides detailed information on user handling opportunities, schedules, equipment, responsibilities, reporting and data collection activities to be performed. The intent of this document is to provide users of the TRUPACT-1 with a guidance document, complete with references, that will allow the smooth introduction of this new transportation system by providing the information necessary for collecting operational, performance and cost data. These data will be used in modeling and full fleet design and procurement activities. In addition, these data will help fine tune procedures in the inspection and maintenance document and the operational document. Additional objectives of this plan are to aid in the establishment of site operational, inspection and maintenance procedures as well as training of site operators and briefing state and local officials.

  7. Future of fusion implementation

    International Nuclear Information System (INIS)

    For fusion to become available for commercial use in the 21st century, R and D must be undertaken now. But it is hard to justify these expenditures with a cost/benefit oriented assessment methodology, because of both the time-frame and the uncertainty of the future benefits. Focusing on the factors most relevant for current consideration of fusion's commercial prospects, i.e., consumption levels and the outcomes for fission, solar, and coal, many possible futures of the US energy system are posited and analyzed under various assumptions about costs. The Reference Energy System approach was modified to establish both an appropriate degree of detail and explicit time dependence, and a computer code used to organize the relevant data and to perform calculations of system cost (annual and discounted present value), resource use, and residuals that are implied by the consumptions levels and technology mix in each scenario. Not unreasonable scenarios indicate benefits in the form of direct cost savings, which may well exceed R and D costs, which could be attributed to the implementation of fusion

The Central European market are the eleven countries Albania, Bulgaria, Croatia, Czech Republic, Hungary, Macedonia, Poland, Romania, Serbia and Montenegro, Slovakia, and Slovenia, with a total population of 121 million. This market is comparable to combined France and Italy in terms of population, but only 30% of its size in terms of GDP

  10. Centralized digital control of accelerators

    International Nuclear Information System (INIS)

    In contrasting the title of this paper with a second paper to be presented at this conference entitled Distributed Digital Control of Accelerators, a potential reader might be led to believe that this paper will focus on systems whose computing intelligence is centered in one or more computers in a centralized location. Instead, this paper will describe the architectural evolution of SLAC's computer based accelerator control systems with respect to the distribution of their intelligence. However, the use of the word centralized in the title is appropriate because these systems are based on the use of centralized large and computationally powerful processors that are typically supported by networks of smaller distributed processors

    Full Text Available Abstract Background There has been an increased interest in the use of telemedical applications in clinical practice in recent years. Considerable effort has been invested in trials and experimental services. Yet, surprisingly few applications have continued beyond the research and development phase. The aim of this study is to explore characteristics of successfully implemented telemedical applications. Methods An extensive search of telemedicine literature was conducted in order to identify relevant articles. Following a defined selection process, a small number of articles were identified that described characteristics of successfully implemented telemedical applications. These articles were analysed qualitatively, drawing on central procedures from Grounded Theory (GT, including condensation and categorisation. The analysis resulted in a description of features found to be of importance for a successful implementation of telemedicine. Subsequently, these features were discussed in light of Science and Technology studies (STS and the concept of 'social negotiation'. Results Telemedical applications introduced into routine practice are typically characterised by the following six features: 1 local service delivery problems have been clearly stated, 2 telemedicine has been seen as a benefit, 3 telemedicine has been seen as a solution to political and medical issues, 4 there was collaboration between promoters and users, 5 issues regarding organizational and technological arrangements have been addressed, and 6 the future operation of the service has been considered. Conclusion Our findings support research arguing that technologies are not fixed entities moving from invention through diffusion and into routine use. Rather, it is the interplay between technical and social factors that produces a particular outcome. The success of a technology depends on how this interplay is managed during the process of implementation.

    Full Text Available The first issue of Philosophical Transactions from the Royal Society published in 1665 is widely regarded as the beginning of modern academic communication through journal articles. This form of presentation was an alternative to books for facilitating the exchange of ideas among scholarly circles. Soon journal collections and scientific libraries were created and eventually an evaluation of the quality of research activity was sought through noting the impact of their publications1. With guidance from the National University of Colombia and support from Scielo Brazil, in 2013 the standards of the US-NLM were implemented and technical endorsement by Pubmed Central was attained.  Colombia Médica´s retention over time is guaranteed by the US-NLM; as of 2014 it will become part of PubMed Central, the free digital archive of biomedical and biological sciences of the U.S. National Institute of Health, which is considered to be the most important digital library in the world. The guidance of the journals by multidisciplinary teams, the policy of free access to its contents, and the technological transfer with the use of free software will help the journals of middle and low-income countries to overcome barriers to diffusion and to maintain technological independence from commercial publishers. Colombia Médica makes an impassioned plea to WHO/PAHO to support BIREME, Brazil and convert SciELO into a certified digital repository.

    This paper shows that delegation of monetary policy to a weight-conservative central banker is optimal, although the government can also use an inflation contract, an employment target, an inflation target, or any combination of these, to control the central banker. The key feature of our model is a stochastic inflation bias, arising when wage-setters receive some information about a supply shock prior to signing nominal wage contracts. Weight-conservatism is shown to be desirable if the stoc...

    Full Text Available Software Stability Modeling (SSM is a promising software development methodology based on object-oriented programming to achieve model level stability and reusability. Among the three critical categories of objects proposed by SSM, the business objects play a critical role in connecting the stable problem essentials (enduringbusiness themes and the unstable object implementations (industry objects. The business objects are especially difficult to implement and often raise confusion in the implementation because of their unique characteristics: externally stable and internally unstable. The implementation and code level stability is not the major concern. How to implement the objects in a stable model through object-oriented programming without losing its stability is a big challenge in the real software development. In this paper, we propose new methods to realize the business objects in the implementation of stable model. We also rephrase the definition of the business objects from the implementation perspective, in hope the new description can help software developers to adopt and implement stable models more easily. Finally, we describe the implementation of a stable model for a balloon rental resource management scope to illustrate the advantages of the proposed method.

Money growth targeting generally leads to higher inflation variability than in...

    A key reason for the consistent gaps between evidence and practice across all areas of medicine is that there has been little attempt to identify or target factors critical for successful implementation of an evidence-based intervention. There is either no explicit implementation strategy or the strategy is based on a best guess rather than on a systematic assessment of crucial barriers and enablers. A different approach is needed to close the evidence-practice gap and thereby achieve the triple aim of improved health, improved patient experience and reduced healthcare costs. We present three fundamental principles of implementation science, which is a methodology that offers a systematic and comprehensive approach to improving healthcare practice and a series of 'how to' steps to conduct implementation science research. In an accompanying article, a scoping review of the types of implementation science research conducted in emergency medicine is reviewed, and several of the principles related to this review are discussed.

    Full Text Available Modern cryptography techniques are virtually unbreakable. As the Internet and other forms of electronic communication become more prevalent, electronic security is becoming increasingly important. Cryptography is used to protect e-mail messages, credit card information, and corporate data. The design of the cryptography system is a conventional cryptography that uses one key for encryption and decryption process. The chosen cryptography algorithm is stream cipher algorithm that encrypt one bit at a time. The central problem in the stream-cipher cryptography is the difficulty of generating a long unpredictable sequence of binary signals from short and random key. Pseudo random number generators (PRNG have been widely used to construct this key sequence. The pseudo random number generator was designed using the Artificial Neural Networks (ANN. The Artificial Neural Networks (ANN providing the required nonlinearity properties that increases the randomness statistical properties of the pseudo random generator. The learning algorithm of this neural network is backpropagation learning algorithm. The learning process was done by software program in Matlab (software implementation to get the efficient weights. Then, the learned neural network was implemented using field programmable gate array (FPGA.

    Full Text Available Whilst being hailed as the remedy to the world's ills, cities will need to adapt in the 21(st century. In particular, the role of public transport is likely to increase significantly, and new methods and technics to better plan transit systems are in dire need. This paper examines one fundamental aspect of transit: network centrality. By applying the notion of betweenness centrality to 28 worldwide metro systems, the main goal of this paper is to study the emergence of global trends in the evolution of centrality with network size and examine several individual systems in more detail. Betweenness was notably found to consistently become more evenly distributed with size (i.e. no "winner takes all" unlike other complex network properties. Two distinct regimes were also observed that are representative of their structure. Moreover, the share of betweenness was found to decrease in a power law with size (with exponent 1 for the average node, but the share of most central nodes decreases much slower than least central nodes (0.87 vs. 2.48. Finally the betweenness of individual stations in several systems were examined, which can be useful to locate stations where passengers can be redistributed to relieve pressure from overcrowded stations. Overall, this study offers significant insights that can help planners in their task to design the systems of tomorrow, and similar undertakings can easily be imagined to other urban infrastructure systems (e.g., electricity grid, water/wastewater system, etc. to develop more sustainable cities.

    Structure of real networked systems, such as social relationship, can be modeled as temporal networks in which each edge appears only at the prescribed time. Understanding the structure of temporal networks requires quantifying the importance of a temporal vertex, which is a pair of vertex index and time. In this paper, we define two centrality measures of a temporal vertex based on the fastest temporal paths which use the temporal vertex. The definition is free from parameters and robust against the change in time scale on which we focus. In addition, we can efficiently compute these centrality values for all temporal vertices. Using the two centrality measures, we reveal that distributions of these centrality values of real-world temporal networks are heterogeneous. For various datasets, we also demonstrate that a majority of the highly central temporal vertices are located within a narrow time window around a particular time. In other words, there is a bottleneck time at which most information sent in the temporal network passes through a small number of temporal vertices, which suggests an important role of these temporal vertices in spreading phenomena.

    Structure of real networked systems, such as social relationship, can be modeled as temporal networks in which each edge appears only at the prescribed time. Understanding the structure of temporal networks requires quantifying the importance of a temporal vertex, which is a pair of vertex index and time. In this paper, we define two centrality measures of a temporal vertex by the proportion of (normal) vertex pairs, the quickest routes between which can (or should) use the temporal vertex. The definition is free from parameters and robust against the change in time scale on which we focus. In addition, we can efficiently compute these centrality values for all temporal vertices. Using the two centrality measures, we reveal that distributions of these centrality values of real-world temporal networks are heterogeneous.

    Various methods of the physics brought many informations on the nuclear elements which one can arrange some ponderable quantities, what is the case of the steady elements and some, unsteady elements, as most of natural radioelements. On the other hand, elements of shorter life duration, and notably those that are carried to an excited state, are more badly known, and one can get information to their consideration that by the mediator of the properties of the transitions that they undergo, when they give birth has best-known nuclear cash: among these transitions represent the isomeric transitions. The goal of this work is the survey of the isomeric transitions from metastable states of short period, included in the domain of the microsecond to some milliseconds. The method of the deferred coincidences has been put to the point and applied in this goal while using the advantages of the selectors to several channels, under two main aspects where the device to several channels was either a selector of time, either a selector of amplitudes. This method served to study the working of Geiger-Muller counter and to measure with precision the period of {sup 181}Ta{sup *} in of the varied experimental conditions. The adopted value is 17,2 {+-}0,2 {mu}s. This work also found an immediate practical application to the setting in evidence of very weak quantities of hafnium in zirconium, of which it constitutes a tenacious and difficult impurity to analyze by the ordinary ways.

    Healthcare technology is used to improve delivery of safe patient care by providing tools for early diagnosis, ongoing monitoring, and treatment of patients. This technology includes bedside physiologic monitors, pulse oximetry devices, electrocardiogram machines, bedside telemetry, infusion pumps, ventilators, and electronic health records. Healthcare costs are a challenge for society, and hospitals are pushed to lower costs by discharging patients sooner. Healthcare technology is being used to facilitate these early discharges. There is little understanding of how healthcare facilities purchase, implement, and adopt technology. There are two areas of theories and models currently used when investigating technology: technology adoption and implementation science. Technology adoption focuses mainly on how the end users adopt technology, whereas implementation science describes methods, interventions, and variables that promote the use of evidence-based practice. These two approaches are not well informed by each other. In addition, amplifying the knowledge gap is the limited conceptualization of healthcare technology implementation frameworks. To bridge this gap, an all-encompassing model is needed. To understand the key technology implementation factors utilized by leading healthcare facilities, the prevailing technology adoption and implementation science theories and models were reviewed. From this review, an integrated technology implementation model will be set forth. PMID:25799235

    ENSI, the regulatory body of the Swiss Confederation, assesses and monitors the nuclear safety of nuclear facilities in Switzerland. These include the five nuclear power plants (NPPs), the plant-based interim storage facilities, the Central Interim Storage Facility (ZWILAG) at Wuerenlingen, as well as the nuclear facilities at the Paul Scherrer Institute (PSI) and the two universities of Basel and Lausanne (EPFL). Its regulatory obligations also include the transport of radioactive materials from and to nuclear facilities and the preparation of a deep geological repository for radioactive waste. ENSI maintains its own emergency organisation that would be activated in case of a serious incident at a nuclear facility in Switzerland. The legislative framework for ENSI's regulatory functions are the Nuclear Energy Act (KEG), the Nuclear Energy Ordinance (KEV), the Radiological Protection Act (StSG), the Radiological Protection Ordinance (StSV), as well as other ordinances and regulations related to reactor safety, the training of operating personnel, the organisation of the emergency response to increases in radioactivity, the transport of radioactive materials, and the deep geological repository. ENSI formulates and updates guidelines that stipulate the criteria by which it evaluates the activities and plans put forward by the operators of nuclear facilities. It regularly publishes reports and provides the public with information on events and findings at nuclear facilities. Chapters 1 to 4 of this Surveillance Report are devoted to the five Swiss NPPs. For each plant, the ENSI evaluation concludes with a safety ranking: high, good, satisfactory and unsatisfactory. Chapter 5 deals with ZWILAG for the processing and interim storage of radioactive waste from Swiss nuclear facilities. Chapters 6 and 7 deal with the nuclear facilities at PSI and with the research reactors at Basel and at EPFL. Chapter 8 deals with the transport of radioactive materials from and to

    In contrasting the title of this paper with a second paper to be presented at this conference entitled Distributed Digital Control of Accelerators, a potential reader might be led to believe that this paper will focus on systems whose computing intelligence is centered in one or more computers in a centralized location. Instead, this paper will describe the architectural evolution of SLAC's computer based accelerator control systems with respect to the distribution of their intelligence. However, the use of the word centralized in the title is appropriate because these systems are based on the use of centralized large and computationally powerful processors that are typically supported by networks of smaller distributed processors.

    2016-05-01

    The transition from wake to sleep is accompanied by a host of physiologic changes, which result in major alterations in respiratory control and may result in sleep-related breathing disorders. The central sleep apneas are a group of sleep-related breathing disorders that are characterized by recurrent episodes of airflow reduction or cessation due to a temporary reduction or absence of central respiratory drive. The fundamental hallmark of central sleep apnea (CSA) disorders is the presence of ventilatory control instability; however, additional mechanisms play a role in one or more specific manifestations of CSA. CSA may manifest during conditions of eucapnia/hypocapnia or chronic hypercapnia, which is a useful clinical classification that lends understanding to the underlying pathophysiology and potential therapies. In this review, an overview of normal breathing physiology is provided, followed by a discussion of pathophysiologic mechanisms that promote CSA and the mechanisms that are specific to different manifestations of CSA.

  6. Design, Implementation and Characterization of a Cooperative Communications System

    CERN Document Server

    2011-01-01

    Cooperative communications is a class of techniques which seek to improve reliability and throughput in wireless systems by pooling the resources of distributed nodes. While cooperation can occur at different network layers and time scales, physical layer cooperation at symbol time scales offers the largest benefit in combating losses due to fading. However, symbol level cooperation poses significant implementation challenges, especially in synchronizing the behaviors and carrier frequencies of distributed notes. We present the implementation and characterization of a complete, real-time cooperative physical layer transceiver built on the Rice Wireless Open-Access Research Platform (WARP). In our implementation autonomous nodes employ physical layer cooperation without a central synchronization source, and are capable of selecting between non-cooperative and cooperative communication per packet. Cooperative transmissions use a distributed Alamouti space-time block code and employ either amplify-and-forward or...

  7. Central Plateau Cleanup at DOE's Hanford Site - 12504

    International Nuclear Information System (INIS)

    wells. As a companion to the Hanford Site Cleanup Completion Framework document, DOE issued its draft Central Plateau Cleanup Completion Strategy in September 2009 to provide an outline of DOE's vision for completion of cleanup activities across the Central Plateau. As major elements of the Hanford cleanup along the Columbia River Corridor near completion, DOE believed it appropriate to articulate the agency vision for the remainder of the cleanup mission. The Central Plateau Cleanup Completion Strategy and the Hanford Site Cleanup Completion Framework were provided to the regulatory community, the Tribal Nations, political leaders, the public, and Hanford stakeholders to promote dialogue on Hanford's future. The Central Plateau Cleanup Completion Strategy describes DOE's vision for completion of Central Plateau cleanup and outlines the decisions needed to achieve the vision. The Central Plateau strategy involves steps to: (1) contain and remediate contaminated groundwater, (2) implement a geographic cleanup approach that guides remedy selection from a plateau-wide perspective, (3) evaluate and deploy viable treatment methods for deep vadose contamination to provide long-term protection of the groundwater, and (4) conduct essential waste management operations in coordination with cleanup actions. The strategy will also help optimize Central Plateau readiness to use funding when it is available upon completion of River Corridor cleanup projects. One aspect of the Central Plateau strategy is to put in place the process to identify the final footprint for permanent waste management and containment of residual contamination within the 20-square-mile Industrial-Exclusive Area. The final footprint identified for permanent waste management and containment of residual contamination should be as small as practical and remain under federal ownership and control for as long as a potential hazard exists. Outside the final footprint, the remainder of the Central Plateau will be

  8. Energy reforms in central and eastern Europe - The first year

    International Nuclear Information System (INIS)

    The first stages of the energy reforms in central and eastern Europe - taking stock of the heritage of the past and conceptualizing the nature of reforms - were accomplished in 1990. While two countries - the USSR and Albania -introduced some market economy elements into central energy planning and basically maintained the latter, all other countries of central and eastern Europe opted for a replacement of central energy planning by market-oriented energy policies and practices. In those latter countries, a typical policy of market adaptation emerged consisting of a change of policies, institutions, economic instruments and relations. Differences in the conditions prevailing in the various countries resulted in the emergence of specific national ''models'' of market adaptation. The reforms, if successful, would imply: greater energy efficiency, reduced pollution, enhanced nuclear safety, a reduced impact on the climate, greater business opportunities, the closure of uneconomic capacities, a decline of coal production, a rise in unemployment; a rise of the energy trade dependence coupled with a rise of gas and oil imports; but practically no change of the net energy exports of the USSR. By the end of 1990 developed market economies agreed to co-ordinate assistance (within the ''Group of 24'') and determined the type and modalities of support. This support would enable and encourage the economies in transition to finalize reform, stimulate their practical implementation and address side effects (disinvestments, unemployment) and systematic risks (e.g. trade dependence) and opportunities (e.g. trade diversification). The business community and lending institutions would have to assess and support investments opportunities more actively. Intergovernmental organizations will play an important role in improving the conditions for business involvement. In 1990, the frameworks for energy reforms in central and eastern Europe, short term assistance, long term business

    It is important to recognize the process of implementing systems as a process of change. The hospital, through its steering committee, must manage this process, initiating change instead of responding to it. Only then will the implementation of information systems be an orderly process and the impact of these changes on the hospital's organization clearly controlled. The probability of success in implementing new systems would likely be increased if attention centers on gaining commitment to the project, gaining commitment to any changes necessitated by the new system, and assuring that the project is well defined and plans clearly specified. These issues, if monitored throughout the systems implementation, will lead to early identification of potential problems and probable failures. This highly increases the chance of success. A probably failure, once identified, can be given specific attention to assure that associated problems are successfully resolved. The cost of this special attention, monitoring and managing systems implementation, is almost always much less than the cost of the eventual implementation failure. PMID:7106436

  12. From Centrality to Temporary Fame: Dynamic Centrality in Complex Networks

    OpenAIRE

    Braha, Dan; Bar-Yam, Yaneer

    2006-01-01

    We develop a new approach to the study of the dynamics of link utilization in complex networks using records of communication in a large social network. Counter to the perspective that nodes have particular roles, we find roles change dramatically from day to day. "Local hubs" have a power law degree distribution over time, with no characteristic degree value. Our results imply a significant reinterpretation of the concept of node centrality in complex networks, and among other conclusions su...

    The transmission systems operation division within Manitoba Hydro is facing increasing demands and challenges in the frequency and complexity of regulatory reporting. In addition, data quality and system integration challenges burden transmission staff across multiple business units. In order to solve these problems, Manitoba Hydro wants to provide an infrastructure for external users outside of the control center that allows them to access energy management systems (EMS)/supervisory control and data acquisition (SCADA) data in an intuitive and exhaustive manner without specific knowledge of EMS systems. This paper presented an overview of the situation and main challenges as well as the requirements for the proposed infrastructure. The paper also presented an overview of the architecture and main components of the proposed system. The actual high-level interactions and data flows between business and the information technology (IT) infrastructure supporting these data exchanges were illustrated. The system scope, size and performance were described. The paper concluded with a discussion of the benefits of the solution and its underlying shift in the IT approach, such as improved quality of data for benchmarking and performance measurement activities as well as improved ability to manage planned outages and track forced outages. 2 refs., 1 tab., 4 figs.

    2014-05-01

    Soil conservation in arable farming still needs further develeopment. Best Management Practices in soil cultivation are techniques that maintain and improve soil conditions and minimise the risk of degradation. However, farmers are still reluctant in anticipating these practices. Identifying and overcoming barriers might help to improve acceptance of Best Management Practices. Based on a set of management practices, such as non-inversion tillage, catch crops and crop rotation, we studied farmers attitudes to these practices. Inquieries were carried out in arable regions of Germany to obtain data on farmers perception. Results are discussed in an European context within the Catch-C project.

  1. Centralized versus Decentralized Infrastructure Networks

    CERN Document Server

    Hines, Paul D H; Schläpfer, Markus

    2015-01-01

    While many large infrastructure networks, such as power, water, and natural gas systems, have similar physical properties governing flows, these systems tend to have distinctly different sizes and topological structures. This paper seeks to understand how these different size-scales and topological features can emerge from relatively simple design principles. Specifically, we seek to describe the conditions under which it is optimal to build decentralized network infrastructures, such as a microgrid, rather than centralized ones, such as a large high-voltage power system. While our method is simple it is useful in explaining why sometimes, but not always, it is economical to build large, interconnected networks and in other cases it is preferable to use smaller, distributed systems. The results indicate that there is not a single set of infrastructure cost conditions under which optimally-designed networks will have highly centralized architectures. Instead, as costs increase we find that average network size...

  2. A centralized audio presentation manager

    Energy Technology Data Exchange (ETDEWEB)

    Papp, A.L. III; Blattner, M.M.

    1994-05-16

    The centralized audio presentation manager addresses the problems which occur when multiple programs running simultaneously attempt to use the audio output of a computer system. Time dependence of sound means that certain auditory messages must be scheduled simultaneously, which can lead to perceptual problems due to psychoacoustic phenomena. Furthermore, the combination of speech and nonspeech audio is examined; each presents its own problems of perceptibility in an acoustic environment composed of multiple auditory streams. The centralized audio presentation manager receives abstract parameterized message requests from the currently running programs, and attempts to create and present a sonic representation in the most perceptible manner through the use of a theoretically and empirically designed rule set.

  3. Centrality in Interconnected Multilayer Networks

    2013-01-01

    Real-world complex systems exhibit multiple levels of relationships. In many cases, they require to be modeled by interconnected multilayer networks, characterizing interactions on several levels simultaneously. It is of crucial importance in many fields, from economics to biology, from urban planning to social sciences, to identify the most (or the less) influent nodes in a network. However, defining the centrality of actors in an interconnected structure is not trivial. In this paper, we capitalize on the tensorial formalism, recently proposed to characterize and investigate this kind of complex topologies, to show how several centrality measures -- well-known in the case of standard ("monoplex") networks -- can be extended naturally to the realm of interconnected multiplexes. We consider diagnostics widely used in different fields, e.g., computer science, biology, communication and social sciences, to cite only some of them. We show, both theoretically and numerically, that using the weighted monoplex obta...

  5. A Randomized Central Limit Theorem

    Eliazar, Iddo; Klafter, Joseph

    2010-05-01

    The Central Limit Theorem (CLT), one of the most elemental pillars of Probability Theory and Statistical Physics, asserts that: the universal probability law of large aggregates of independent and identically distributed random summands with zero mean and finite variance, scaled by the square root of the aggregate-size (√{n}), is Gaussian. The scaling scheme of the CLT is deterministic and uniform - scaling all aggregate-summands by the common and deterministic factor √{n}. This Letter considers scaling schemes which are stochastic and non-uniform, and presents a "Randomized Central Limit Theorem" (RCLT): we establish a class of random scaling schemes which yields universal probability laws of large aggregates of independent and identically distributed random summands. The RCLT universal probability laws, in turn, are the one-sided and the symmetric Lévy laws.

    2014-11-01

    The present status and future plans of the physics program of Central Exclusive Production (CEP) at RHIC are described. The measurements are based on the detection of the forward protons from the Double Pomeron Exchange (DPE) process in the Roman Pot system and of the recoil system of charged particles from the DPE process measured in the STAR experiment's Time Projection Chamber (TPC). The data described here were taken using polarized proton-proton collisions at √ {s} = 200 GeV. The preliminary spectra of two-pion mass reconstructed by STAR TPC in central region of pseudorapidity |η| < 1, are presented. Near future plans to take data with the current system at center-of-mass energy √ {s} = 200 GeV and plans to upgrade the forward proton tagging system are presented. Also a possible addition of the RPs to the sPHENIX detector is discussed.

    Plague in man occurred from 1968 to 1970 in mountain villages of the Boyolali Regency in Central Java. Infected fleas, infected rats, and seropositive rats were collected in villages with human plague cases. Subsequent isolations of Yersinia pestis and seropositive rodents, detected during investigations of rodent plague undertaken by the Government of Indonesia and the WHO, attested to the persistence of plague in the region from 1972 to 1974.

  15. MR findings of central nerocytoma

    International Nuclear Information System (INIS)

    Central neurocytoma is a reae neuronal differentiated intraventricular tomor of young adults. The purpose of this study was to evaluate the characteristic MR appearance of central neurocytoma. We retrospectively reviewed MR images of 12 patients with central neurocytoma, confirmed by ultrastructural and immunohistochemical study. We analyzed patient age, and on all sequences, tumor location, extension into the third ventricle, involvement of brain parenchyma, cyst, hemorrhage, vascular signal void and signal intensity ; and egree of Gd-enhancement was examined on MR images, pattern of calcification on CT, and neovascularity, tumor staining on angiography. Age distribution was wide ranging from 26 to 64 years ; the most frequent age group was the fourth decade (five patients). All tumors except one (in the third ventricle) were located in the lateral ventricle and most were seen in the region of the foramen of Monro (10 cases). Tumors showed extension into the third ventricle and involvement of parenchyma in three cases. The internal architecture of the tumor was heterogenous and consisted of cysts (83%), hemorrhage (25%) and vascular signal void (25%). The solid portion of the tumor showed variable signal intensity on T1-weighted images and iso or high signal intensity on T2- and proton density-weighted images. On MR imaging, mild to moderate heterogenous Gd-enhancement was seen in ten cases (83%), and on CT, a spotted, amorphous, nodular pattern of calcifications was seen in seven cases (63%). On angiography, neovasevlarity and tumor staining was seen in three cases (100%). The typical location of the lateral and third ventricles and MR imaging characteristics including variable signal intensity and heterogenous internal architecture are helpful in the diagnosis of central neurocytoma in young adults

  16. Seismotectonic model of Central Europe

    International Nuclear Information System (INIS)

    Earthquakes belong to natural disasters which are associated with tectonic processes in the interior of the Earth. They are extremely devastating in populated areas; they cause human losses and damage personal estates and the environment. To mitigate the potential effects of earthquakes it is necessary that relief and mitigation structures operate following an earthquake, but it is also essential to stimulate and enhance preparedness and prevention. Prevention includes the development of scenarios of potential earthquakes, hazard mapping, formulation of regulations, etc. Preparedness includes the installation and operation of warning systems, establishing communication networks to operate before, during, and after earthquakes. As nuclear technology belongs to high-risk technologies with regard to human health and the environment and its hazard substantially increases in consequence of earthquakes, in the siting of a nuclear plant engineering solutions are generally available to mitigate the potential vibratory effects through design. For the choice of a suitable engineering solution, reliable data must be processed by reliable techniques. The IAEA safety guide of the safety series No. 50-SG-S1(Rev. 1) specifies the demands on data and on their processing and also on the regional seismotectonic model. With a view of this the regional seismotectonic model of Central Europe was created. The paper presents regional geological characteristics of Central Europe and a chronological model of neotectonic movements in Central Europe with specification of neotectonic regional units and their present movements. Moreover, it contains earthquake characteristics for Central Europe and the specification of seismogenic movements. It was found that the genesis of local regions with occurrence of the strongest earthquakes is connected with several movement trends in the last 5 Ma. Six more or less tectonically separate regional units were revealed. The earthquake epicenters often

    Ocelots (Leopardus pardalis) are presumed to be the most abundant of the wild cats throughout their distribution range and to play an important role in the dynamics of sympatric small-felid populations. However, ocelot ecological information is limited, particularly for the Amazon. We conducted three camera-trap surveys during three consecutive dry seasons to estimate ocelot density in Amanã Reserve, Central Amazonia, Brazil. We implemented a spatial capture-recapture (SCR) model that shared detection parameters among surveys. A total effort of 7020 camera-trap days resulted in 93 independent ocelot records. The estimate of ocelot density in Amanã Reserve (24.84 ± SE 6.27 ocelots per 100 km2) was lower than at other sites in the Amazon and also lower than that expected from a correlation of density with latitude and rainfall. We also discuss the importance of using common parameters for survey scenarios with low recapture rates. This is the first density estimate for ocelots in the Brazilian Amazon, which is an important stronghold for the species. PMID:27191598
