    It was with the realisation that the scientific problems associated with regional air pollution could only be solved within the framework of an international interdisciplinary approach that in 1985 EUROTRAC, the European co-ordinated research project, was formed. Such an approach provides the scientific consensus necessary for the acceptance of regional air-pollution abatement measures by the countries affected. EUROTRAC is a EUREKA environmental project, studying the transport and chemical transformation of trace substances and pollutants in the troposphere. Three goals were specified the outset: (1) to increase the basic knowledge in atmospheric science, (2) to promote the technological development of sensitive, specific and fast response instruments for environmental research and development, and (3) to improve the scientific basis for taking future political decisions on environmental management in the European countries. Thus EUROTRAC was founded as a scientific project but had the specific intention that its results should be utilised in the formulation of policy. This presentation reviews the progress made towards each of the three goals and also indicates the proposed direction which a follow-on project is likely to take when EUROTRAC finishes at the end of 1995.

    2002-01-01

    In 1994, the International Atomic Energy Agency started the five-year Co-ordinated Research Project (CRP) on Comparative International Studies of Osteoporosis Using Isotope Techniques. The objectives of this study were: To harmonize the techniques of measuring BMD within the participating countries and to obtain data that can be compared between the different study groups (countries); To determine whether early adult PBM varies between populations over the age range from 15 to 50 years. In other words, to determine the age of peak bone mass in selected populations from developing countries; To explore environmental and nutritional contributions to any determined differences. Further information about the purpose and scope of the CRP may be found in the report of the Advisory Group Meeting (AGM) held in 19921 and other reports of this CRP. The fourth Research Co-ordination Meeting (RCM) for participants of the CRP, which is the subject of the present report, was held at the University of Sheffield Medical School; WHO Collaborating Center for Metabolic Bone Diseases in Sheffield, UK from 28 Feb. to 3 March 2000

  13. First research co-ordination meeting of the co-ordinated research programme on development of kits for radioimmunometric assays for tumour markers. Summary report

    International Nuclear Information System (INIS)

    1997-01-01

    Cancer is one of the major reasons for mortality and a great deal of research goes on in many areas related to cancer all through the world. The concept of 'tumor markers' has greatly aided the management of cancer, especially for follow up of the treated patients. Immunoassays that are used for measurement of sub-picomolar quantities of biomolecules such as hormones have been developed for the measurement of tumor markers too and these are widely used for monitoring the patients. The current co-ordinated research program on 'Development of Immunometric Assays for the Tumor Makers: PSA, free PSA and TPS' was born out of the advise from a group of specialists from the field oncology and nuclear medicine who met to discuss initially (Advisory Group Meeting, Colombo, August 1996) to identify the most appropriate markers and later (Consultants' Meeting, Glasgow, 21-25 April 1997) to identify the details of the procedure to follow. The first Research Co-ordination Meeting of this group was held in Vienna from 9-12 December 1997 to review the plans of each participant and the steps to be taken to realize the goal of this CRP. The meeting was attended by participants from the ten laboratories. The meeting discussed all salient aspects of the IRMA development for PSA and TPS. The modalities of working out the plans were thoroughly considered and the key inputs for the program to take off were identified. In conclusion, all the nine contract holding participants would develop the IRMAs for PSA (free and total) and TPS (Uruguay)

  19. Co-ordinated research programme on development and application of isotopic techniques in studies of vitamin A nutrition. Report of the first research co-ordination meeting

    International Nuclear Information System (INIS)

    1997-01-01

    In Vitamin A nutrition, evaluations to ascertain the efficacy of intervention strategies are becoming increasingly important. However, state-of-the-art methods for evaluating vitamin A status often do not provide enough quantitative information on vitamin A status and the bioconversion of carotenoids, particularly in people with subclinical vitamin A deficiency. These limitations have had programmatic consequences. The principal reason the new Coordinated Research programme (CRP) was formulated was to improve techniques for measuring vitamin A status and the bioconversion of carotenoids to vitamin A with the expectation that the new methods could contribute meaningfully to field-based evaluations of the efficacy of intervention strategies. The International Atomic Energy Agency (IAEA) is sponsoring programmes to develop and transfer isotopic techniques to improve nutrition monitoring in developing countries. The New CRP ''Development and Application of Isotopic Techniques in Studies of Vitamin A Nutrition'' has seven teams, six of which are working to develop methods based on orally administered isotopically labelled retinol which will be a valid measure of whole body retinol (mostly hepatic reserves) and useful under typical field conditions, particularly in women and children with marginal vitamin A deficiency. The seventh team is biosynthesizing uniformly deuterated β-carotene by growing foods in deuterated water. This report summarizes the research to be undertaken, as presented at the first Research Co-ordination Meeting

    1999-01-01

    The concept for the Co-ordinated Research Programme on isotopic evaluations of maternal and child nutrition to help prevent stunting was a consequence of discussions held between IAEA staff and participants in a regional training course on 'Isotope Techniques in Human Nutrition' held in Lima, Peru in June 1996. The intention then was to develop research on factors influencing the success of lactation and the consequent effects on the breast-fed child. The project would have Latin American participants to promote regional exchange of expertise and ideas. Initial participation was from Argentina, Chile, Mexico, Peru and Venezuela. Brazil and Pakistan have now been added to these. There are three Specific Research Objectives: (1) To develop stable isotope methods for measuring breast-milk intake using regionally available equipment. (2) To apply the methodology in the assessment of milk intake in infants in relation to maternal nutrition, socio-economic status and education, and infant nutrition and intake of macro- and micro-nutrients. (3) To use information gathered at 2) to determine the need for supplementation programmes for mothers and/or infants, and educational programmes for the mothers

  8. Co-ordinated research and environmental surveillance programme related to sea disposal of radioactive waste

    International Nuclear Information System (INIS)

    1996-01-01

    The co-ordinated Research and Environmental Surveillance Programme relevant to sea disposal of radioactive waste (CRESP) was created in 1981 in the framework of the 1977 Decision of the OECD Council establishing a Multilateral Consultation and Surveillance Mechanism for Sea Dumping of Radioactive Waste. CRESP was essentially a scientific research programme. Its main objective was to increase the knowledge of processes controlling the transfer of radionuclides in the marine environment, so that safety assessments could be based on more accurate and comprehensive scientific data. From 1986, in response to a request from the Paris Commission, CRESP also considered the scientific aspects of coastal releases. CRESP made it possible to co-ordinate national research activities and generated an important international co-operation in its areas of work. The vast amount of scientific information gathered in this framework increased strongly our knowledge of the impact of radionuclides introduced to the deep sea environment. In particular, CRESP provided the basis for a comprehensive safety analysis of sea dumping operations. This study, published by the NEA in 1985, is still e reference on the subject. In November 1993, the Sixteenth Consultative Meeting of Contracting Parties to the London Convention 1972 voted a total ban on the disposal at sea of radioactive wastes and other radioactive matter. Considering this decision, the conclusions of the 1985 safety analysis, and CRESP's view that new scientific findings are unlikely to alter these conclusions, the NEA Steering Committee for nuclear Energy decided in October 1995 to terminate the programme. The present report summarises the knowledge accumulated within CRESP over its fifteen years of existence. (author)

  9. Bulk hydrogen analysis, using neutrons. Final report of the second research co-ordination meeting

    International Nuclear Information System (INIS)

    1998-11-01

    The aims of the Second Co-ordination Meting (RCM) of the Coordinated Research Programme (CRP) were to report on and review progress against the work programme set at the beginning of the CRP and to discuss the work plans for the second half of the programme. In many cases hydrogen is required to be measured in a bulk medium rather than merely at a surface. For this reason neutrons are used due to their high penetrating power in dense material. In addition, the mass attenuation coefficient for neutrons in hydrogen is significantly larger than for all other elements, meaning that neutrons have a higher probability of interacting with hydrogen than with other elements in the sample matrix. Neutrons have been used in the following areas: Fast Neutron Transmission, Scattering and Activation Technique; Digital Neutron Imaging; Hydrogen Detection by Epithermal Neutrons; Microscopic Behaviour of Hydrogen in Bulk Materials

    In 1986 the Animal Production and Health Section of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture embarked on a programme of support to scientists in developing countries focused on improving animal disease diagnosis through the use of nuclear and related technologies. As part of this programme the Swedish International Development Authority (SIDA) agreed to provide support for a FAO/IAEA Co-ordinated Research Project (CRP) concerned with the introduction and use of such technologies in Latin America. Through this programme, which was entitled Regional Network for Latin America on Animal Disease Diagnosis Using Immunoassays and Labeled DNA Probe Techniques, studies were supported on a number of diseases considered to be of substantial economic and social importance to the region, including brucellosis, tuberculosis, babesiosis, leukosis, bluetongue and chlamydia infection in cattle and psedorabies in pigs. One significant conclusion was that large number of diseases studied limited research findings owing to the lack of a critical mass of scientists studying any one specific disease problem. Thus when in 1991, SIDA agreed to follow-up CRP on Immunoassay Methods for the Diagnosis and Epidemiology of Animal Diseases in Latin America, the work was restricted to three diseases, i.e. foot-and-mouth disease (FMD), bovine brucellosis and bovine babesiosis. In 1994 results were presented in Guadeloupe, Lesser Antilles, France. The outcome of this meeting was the validation of ELISAs for the above mentioned diseases and a recommendation that future research should focus on diagnosis and epidemiology to support existing control and eradication campaigns against the two diseases of major importance in the region (FMD and Brucellosis). A follow-up CRP (1994-1997) entitled the Use of ELISA for Epidemiology and Control of Foot-and-Mouth Disease and Bovine Brucellosis in Latin America focused on the further validation and subsequent use of a

  16. Combination processes for food irradiation. Proceedings of the final research co-ordination meeting

    International Nuclear Information System (INIS)

    1998-01-01

    There is an increasing consumer demand for food that is safe, minimally processed, visually attractive, full flavoured, nutritious, and convenient to prepare and serve, that has fewer preservatives, and that is available throughout the year at an affordable cost. Consumer concern and regulatory restrictions on the use of preservatives and pesticides in food are adversely affecting international trade in many food products. As a result, minimally processed, chilled foods and ready to eat foods are increasingly being marketed to satisfy consumer demand in both developed and developing countries. However, such foods could introduce new microbiological risks to the population, especially to those who are immunocompromised or generally at risk (children, pregnant women, the elderly, etc.). In view of these factors, a 5 year Co-ordinated Research Programme (CRP) on Irradiation in Combination with Other Processes for Improving Food Quality was initiated in 1991 by the Food and Agriculture Organization of the United Nations and the International Atomic Energy Agency through their Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. The objectives of this CRP were to evaluate: 1) Combination treatment involving irradiation in order to extend the self-life of meat, seafood, fruits and vegetables at refrigeration temperatures and under ambient conditions; 2) Combination treatment involving irradiation in order to ensure the microbiological safety of foods, both individual and composite, including prepared meals; 3) Shelf-life extension of chilled, prepared meals and the development of shelf stable food and food components through combination treatment involving irradiation; 4) Energy requirements of combination processes involving irradiation in comparison to other food processes. Scientists from 14 countries participated in the CRP by carrying out the work under Research Contracts and Agreements with the Joint FAO/IAEA Division. The first Research Co-ordination

    Poor bone health is a major public health problem of worldwide concern. No country is immune. One of the main concerns - osteoporosis - is a bone disease that usually affects older people (primarily post-menopausal women), leading to hip fractures, vertebral compression fractures, and other related problems.In 1994 the IAEA (henceforth the `Agency`) started a 5-year Co-ordinated Research Programme (CRP) which addresses one particular measure of bone health - bone mineral density (BMD). The main concept underpinning this CRP is that good bone health in later years is primarily determined by the attainment of a sufficiently high BMD during early adulthood. The `core` objective of the Agency`s CRP is to investigate how BMD varies with the age, sex, ethnicity and geographical origin of the subjects over the age range from 15 to 50 years. This is being done in the hopeful expectation that, by looking at a large number of population groups with different lifestyle, nutritional and other parameters, it might be possible to obtain some new insights into which factors are important for attaining a high value of BMD during early adulthood, and for being able to maintain it at a sufficiently high level into old age. The Second Research Co-ordination Meeting (RCM) for participants in the CRP - which is the subject of the present report - was held at the University of California San Diego (UCSD), USA. An overview of the data on BMD reported by the participants during the meeting. It is concluded that the CRP participants have gathered an impressive amount of data over the last 2 years. Given the fact that some age groups contain relatively small numbers of subjects, the statistical uncertainties are still relatively large. Nevertheless, there do appear to be quite marked differences in BMD across the centres, approaching approximately 10%. If confirmed, this could represent a major difference in fracture risk for the future, if all other factors (bone quality, weight, fall

    Where fissile materials are being processed in quantities exceeding the minimum critical amounts, a radiation risk to workers arises from the possibility of criticality excursions. Despite the fact that techniques for preventing the occurende of such accidental excursions have reached very high standards it is generally agreed that the availability of suitable nuclear accident dosimetry (NAD) systems is very important. Following the recommendations of an Advisory Group meeting on NAD, the IAEA had established in 1969 an international coordinated research programme on NAD systems and elaborating standarized systems. A large number of research groups from 14 Member States throughout the world participated in this co-ordinated work. Since 1970 four international multilaboratory intercomparison experiments on NAD have been organized and the response of a variety of dosimeters examined in different neutron spectra under simulated accident conditions at Valduc (France), Oak Ridge (USA), Vinca (Yugoslavia) and Harwell (UK). The results achieved in these intercomparison studies show that NAD systems have been substantially improved and that several systems are available now in a number of laboratories throughout the world that perform within the criteria laid down by the initiating advisory group in 1969. A compendium of neutron leakage spectra has also been elaborated for facilitating the determination of dose from readings of detectors exposed to various neutron fields in criticality accidents

    Sea disposal operations of packaged low-level radioactive waste are carried out under the provisions of the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, also referred to as the London Dumping Convention. The environmental impact of this disposal method is continuously kept under review, in particular within the IAEA which has provided the ''Definition of High-Level Radioactive Waste or Other High-Level Radioactive Matter Unsuitable for Dumping at Sea'' for the purpose of the Convention and within the OECD-NEA in the framework of its Multilateral Consultation and Surveillance Mechanism for Sea Dumping of Radioactive Waste. The NEA Co-Ordinated Research and Environmental Surveillance Programme (CRESP) is focussed on the actual North-East Atlantic dump site. Its objective is to increase the available scientific data base related to the oceanographic and biological characteristics of the dump site and elaborate a site specific model of the transfers of radionuclides to human populations. Future site suitability reviews, as periodically requested under the terms of the Multilateral Consultation and Surveillance Mechanism, will therefore be based on a more accurate and comprehensive scientific basis

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

  2. Co-ordinated research programme on nuclear techniques for toxic elements in foodstuffs

    International Nuclear Information System (INIS)

    1988-01-01

    The purpose of this Co-ordinated Research Programme (CRP) is to obtain comparative data on the existing elemental concentrations of potentially toxic elements in foodstuffs in various countries. This study is also intended to provide information on the dietary intakes of toxic elements as a means to detect potential health hazards to the population groups concerned. This study has important economic implications since trade in foodstuffs is dependent on compliance with regulations pertaining to maximum permissible concentrations. An important supplementary purpose of the programme is to help establish analytical expertise for work of this kind in individual countries, allowing such laboratories to offer analytical quality control services. The programme has centred its objective on the determination of important toxic elements such as As, Cd, Cr, Hg, Pb and Se, in addition to Cu, Sb and Zn, which are also potentially toxic but are generally of minor importance from the point of view of public health. The matrices of interest are foodstuffs which comprise together more than 50% of the average daily intake. Drinking water is also of high importance and should be analysed as well.

    In order to explore this approach, a Co-ordinated Research Programme (CRP) on the Use of Isotope Studies for Increasing and Stabilizing Plant Productivity in Low Phosphate and Semi-arid and Sub-humid Soils of the Tropics and Sub-tropics was initiated in October 1989 and complete in October 1994. Almost half of the work carried out under this programme concentrated on water use efficiency and the rest on phosphate use efficiency. Egypt, Morocco and Tunisia focused on wheat; Nigeria and Sierra Leone on cowpea; Kenya, Sudan and the United Republic of Tanzania on nitrogen fixing trees such as Prosopis, Acacia and Gliricidia; and Viet Nam on rice. Experiments conducted in the field showed that there is a wealth of genetic diversity among the genotypes/provenances of crop and tree species in their capacity for uptake and use of phosphorus and water from soils limited in resources. Several elite genotypes/provenances were identified which are highly efficient in water or phosphate use. In a few cases, the high water use efficiency (or the high phosphorus use efficiency) feature was seen in the same genotype where the grain yield was also high. Morphological parameters responsible for making some genotypes superior in their capacity to use phosphorus or water have also been investigated. It is our hope that the findings reported in this publication will help agricultural scientists in the Member States, particularly in Africa, in their quest of finding solutions to problems of food security.

    In the developed countries, research using nuclear methods has been substantially used to examine the physiological and biochemical mechanisms involved in obesity-related diseases. This Co-ordinated Research Project (CRP) is intended to promote the use of these techniques in the developing world. The specific objectives of this CRP are: 1. To define the magnitude of the obesity/NIDDM problem in developing countries. 2. To identify vulnerable groups at high risk. 3. To describe the metabolic mechanisms involved. The purpose of this first Research Co-ordination Meeting (RCM) was thus to develop a worldwide collaboration in the use of nuclear and isotopic techniques to investigate the aetiology of degenerative diseases in ageing. All countries participating in this CRP are going through the epidemiological transition with changes in lifestyles to approach those seen in the developed nations.

    The Research Coordination Meeting was held in Mito City, Japan on October 17-21, 1988, inviting the chief investigating scientists from 11 RCA member countries to discuss practical plans for the Coordinated Research Program (CRP) on 'Compilation of Anatomical, Physiological and Metabolic Characteristics for a Reference Asian Man' based on the decision taken at the Project Formulation Meeting for the RCA Project 'Strengthening Radiation Protection' Tokyo, November 1987. Significance of the setting 'Reference Man' for Asian peoples to estimate more realistic radiation doses by applying the real typical physical, physiological and metabolic parameters for them instead of those recommended by ICRP based on the data for 'Caucasian Man' has been indicated by whole member countries and recognized again at the Meeting. The present status of 'Reference Man-oriented Studies' in each countries was presented by the participants and certain difference or difficulties were pointed out among the countries depending on the geographical, social, or economical conditions as well as the ethnic circumstances. After the mutual discussions and exchange of up-to-date information, the general conclusions were drawn as follows: acknowledging the importance of the CRP, research works should be carried out in each country with the expected supports from IAEA and other member countries. The first priority is given on the measurements of human physique (and internal organs) followed by the food consumption survey. Trace element analysis would be done by the countries where possible. The standard manual for data collection might be necessary. The establishments of Co-ordination Center or central body with data base and also subgroup systems are desirable to promote the CRP.

The Centre has been founded as a result of an agreement between four institutions: the Danish Institute of Agricultural Sciences (DIAS, the Danish Veterinary Laboratory (DVL, the Danish Veterinary Institute for Virus Research (DVIV and The Royal Veterinary and Agricultural University (KVL. CEPROS is a "research centre without walls" and is physically located as an integrated part of the four institutions named above. The Centre has close collaboration with the industry. The superior goals of the Centre are to co-ordinate fundamental and applied research and simultaneously integrate the veterinary and the production oriented livestock research within animal health and welfare, taking into consideration the production economics and reduced use of medication. The assignment of the Centre is to initiate and carry out research, aiming to investigate the influence of breeding and production systems on animal health and welfare as well as on production and product quality. The Centre has since 1997 established 16 interdisciplinary research projects dealing with cattle, pigs, poultry, or mink. The scientific content can be divided into three research clusters: A. Management of animal production and health in production systems, B: Pathogenesis of production diseases, and C. Animal health economics. In Cluster A, the physical environments of production systems have been investigated, broader definitions of the concept health have been established and used in identification of risk factors. Cluster B has investigated physiological, immunological and genetic mechanisms behind development of production diseases and how to apply this knowledge in disease prevention.

    A co-ordinated research programme (CRP) on applied research on air pollution using nuclear-related techniques is a global CRP which started in 1992, and is scheduled to run until early 1997. The purpose of this CRP is to promote the use of nuclear analytical techniques in air pollution studies, e.g. NAA, XRF, and PIXE for the analysis of toxic and other trace elements in air particulate matter. The main purposes of the core programme are i) to support the use of nuclear and nuclear-related analytical techniques for research and monitoring studies on air pollution, ii) to identify major sources of air pollution affecting each of the participating countries with particular reference to toxic heavy metals, and iii) to obtain comparative data on pollution levels in areas of high pollution (e.g. a city centre or a populated area downwind of a large pollution source) and low pollution (e.g. rural area). This document reports the discussions held during the second Research Co-ordination Meeting (RCM) for the CRP which took place at ANSTO in Menai, Australia. (author)

    The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture through its Co-ordinated Research Projects (CRPs), has been assisting national agricultural research systems in Member States to develop and apply nuclear and related techniques for improving livestock productivity. The programmes have focused on animal nutrition, animal reproduction and more recently on animal nutrition/reproduction interactions with emphasis on smallholder farming systems. The measurement of microbial protein supply to ruminant livestock has been an important area of research in ruminant nutrition. An estimate of microbial protein contribution to the intestinal protein flow is important for estimating the protein requirement of ruminant animals. Understanding the process of microbial protein synthesis has been difficult however, and due to the lack of simple and accurate methods for measuring microbial protein production in vivo, the methods used are based on complex microbial markers which require surgically prepared animals. As a result of a consultants meeting held in May 1995 to advise the Joint FAO/IAEA Division on the feasibility of using nuclear and related techniques for the development and validation of techniques for measuring microbial protein supply in ruminant animals, an FAO/IAEA Co-ordinated Research Project on Development, Standardization and Validation of Nuclear Based Technologies for Measuring Microbial Protein Supply in Ruminant Livestock for Improving Productivity was initiated in 1996, with a view to validating and adapting this technology for use in developing countries. To assist scientists participating in the CRP, a laboratory manual containing experimental protocols and methodologies for standardization and validation of the urine purine derivative technique and the development of models to suit local conditions, was published as IAEA-TECDOC-945. The present publication contains the final reports from participants in Phase 1 of the project

    With the advent of DNA molecular marker technology in the 1980s plant breeding had a new and powerful tool with which to increase its efficacy. Such markers are abundant and directly reveal information about the genotype and therefore are more useful than simple phenotypic markers. In plant breeding applications, molecular markers reveal information about variability and genetic relationships, and enable genetic mapping, which greatly assists the breeder in selection of parents and progeny, as well as in management of breeding strategies. Furthermore, molecular markers linked to phenotypic traits permit very early selection of superior progenies from breeding populations, therefore significantly reducing the need for field testing and greatly increasing efficiency of plant breeding programmes. For this to occur the oligonucleotide probes for labelling genetic markers and/or the primers for polymerase chain reactions to amplify genetic markers needed to be also accessible to scientists in developing Member States. In addition, technical information, training and troubleshooting were needed to support the utilization of DNA markers. In the early 1990s there was a dramatic increase in requests for access to this technology. This co-ordinated research project (CRP) facilitated the transfer of molecular marker technology, in terms of both material and information, from advanced laboratories to assist breeding programmes in developing countries. Two other CRPs were conducted concurrently in order to assist developing Member States to utilise molecular markers - Application of DNA Based Marker Mutations for Improvement of Cereals and other Sexually Reproduced Crop Plants, and Use of Novel DNA Fingerprinting Techniques for the Detection and Characterisation of Genetic Variation in Vegetatively Propagated Crops (IAEA-TECDOC-1010 and IAEA-TECDOC-1047, respectively). The present CRP built upon the success of the former projects by ensuring the availability of probes

    This publication presents the scientific results obtained under the FAO/IAEA Co-ordinated Research Programme on Improvement of Cereals in Latin America through Mutation Breeding. Some of the selected mutants were already tested in multilocation trials and had higher yields and/or other advantages, in comparison with the leading local varieties. On the basis of these results it it expected that a few new mutant varieties of rice (Brazil, Costa Rica, Cuba, Guatemala), wheat (Brazil, Chile) and barley (Peru) will be officially released within the next few years. Still more mutants, which are valuable for conventional breeding programmes as new sources of desired genes, were selected. Refs, figs and tabs.

  16. Research and development on procedures to stabilize acaricides in livestock dips. Proceedings of a final research co-ordination meeting

    International Nuclear Information System (INIS)

    1997-11-01

    Ticks and mites are serious ectoparasites of livestock in many countries. As vectors of animal diseases they pose a threat to livestock production. Traditionally, different types of acaricides are used to control them. One of the most commonly used tick control techniques is to force animals to walk through an acaricide suspension in a trough or Cattle Dip. Dipping is quite effective as the entire body of the animal gets treated with the acaricide. However, with increased usage the concentration of the acaricide in the 'dip' declines due to removal by the animal and degradation by biological and chemicals processes. The dissipation of the acaricide results in loss of efficacy of the 'dip', and may also enhance the development of resistance by the ectoparasites to the acaricides. Maintenance of an effective concentration, by periodic recharge or stabilization of the acaricide, is essential to assure efficient and cost-effective control and to minimize chances of resistance to develop. In 1990, the FAO/IAEA Joint Division, recognizing the need for co-ordinated research on studying the dissipation of acaricides in cattle dips and developing procedures to stabilize them, established a 5-year Co-ordinated Research Programme on Development of Procedures to Stabilize Acaricides in Livestock Dips and of Simplified Methods to Measure Their Concentration, Using Nuclear Techniques. In initiating this programme, the Joint Division recognized that major gaps exist in the knowledge in this area which, if filled, would greatly aid developing countries in their effort to more effectively use acaricides to protect animal health. This TECDOC reports the accomplishments of this programme

    Environmental pollution is a cause of ever increasing concern in the world. The UN Conference on Environment and Development (Rio, Brazil, 1992) reaffirmed the importance of protecting the environment within the context of sustainable development. Arising out of this conference, the Rio Agenda 21 declaration called for a number of nationally determined action programmes, with international assistance and co-ordination under 'Capacity 21', concerning environmental monitoring and assessment, including the use of biological markers. Environmental protection and control is a matter of high priority in all developing countries' governmental policies in view of its implications for the welfare of the present and future populations. Therefore it is expected that regional and national organisations responsible for legislation and environmental policy, municipal organisations, which could use the data collected for establishing emission levels, organisations responsible for pollutant emission control and public health-related institutions will benefit from this proposed Co-ordinated Research Project (CRP). The CRP is expected to exploit possibilities of developing and validating tools for using appropriate biomonitors to map the distribution of air pollution over wide areas in developing countries. If successful, this would be a powerful way for developing countries to monitor air pollution.

  19. Co-ordinated research programme on isotope-aided studies of the bioavailability of iron and zinc from human diets

    International Nuclear Information System (INIS)

    1992-01-01

    Nutritional deficiencies of essential micronutrients (particularly of iron, but also of zinc and selenium) are known to affect hundreds of millions of people throughout the world, mainly in developing countries. Such deficiencies can lead to significant deficits in mental development, growth, work performance, immune competence and other biological parameters. In many of the population groups that are affected, the deficiencies are thought to be due not to an absolute lack of the element in the diet but rather to is poor bioavailability. Much work has already been done on this subject, particularly in some developed countries and particularly with respect to iron. However, there is still appears to be a need for more research on factors affecting bioavailability and the means to improve it by simple dietary modification and fortification using food products of the kind that may be locally available in developing countries. Isotope techniques potentially have a large role to play in studies of the bioavailability of iron and other trace elements. To support work in this area, the IAEA initiated a Co-ordinated Research Programme (CRP) at the end of 1990 on ''Isotope-Aided Studies of the Bioavailability of Iron and Zinc from Human Diets''. The first Research Co-ordination Meeting (RCM) of participants in this CRP is the subject of the present report. Refs, figs and tabs

    This TECDOC summarizes the results of a Co-ordinated Research Project (CRP) on the Use of Nuclear Techniques for Optimizing Fertilizer Application under Irrigated Wheat to Increase the Efficient Use of Nitrogen Fertilizer and Consequently Reduce Environmental Pollution. The project was carried out between 1994 and 1998 through the technical co-ordination of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. Fourteen Member States of the IAEA and FAO carried out a series of field experiments aimed at improving irrigation water and fertilizer-N uptake efficiencies through integrated management of the complex Interactions involving inputs, soils, climate, and wheat cultivars. Its goals were: to investigate various aspects of fertilizer N uptake efficiency of wheat crops under irrigation through an interregional research network involving countries growing large areas of irrigated wheat; to use 15 N and the soil-moisture neutron probe to determine the fate of applied N, to follow water and nitrate movement in the soil, and to determine water balance and water-use efficiency in irrigated wheat cropping systems; to use the data generated to further develop and refine various relationships in the Ceres-Wheat computer simulation model; to use the knowledge generated to produce a N-rate-recommendation package to refine specific management strategies with respect to fertilizer applications and expected yields

    2000-01-01

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

    Mercury is a global pollutant because of its ability to undergo long distance transport into the atmosphere. In view of these global concerns the IAEA has organised a CRP to elucidate the biological, chemical, and physical factors, which influence the transformations of Hg and its compounds in the ecosystem and the dynamics of the mercury recycling. Under the title 'Health impacts of mercury cycling in contaminated environments studied by nuclear techniques' the CRP was started in October 1999 and concluded in February 2004. This report provides an overview of the various activities performed under the CRP by the various participants. The overall achievements are summarized and those aspects that require a further deeper look are also pointed out. The individual country reports are also given which detail on the progress made by the respective participants, during the CRP period. It is hoped that the results would encourage further research activities on these and related issues in the respective countries with the CRP participant as a catalyst to further these studies

    X-ray fluorescence is a well-established analytical technique widely used in industrial and research applications for materials characterisation. However, a relatively recent development has been the availability of portable instrumentation, which can be used for both the direct in situ non-destructive analysis of samples, and also is readily transportable to field sites for use in a 'mobile laboratory' style of operation. In situ analyses using the XRF technique can make an essential contribution to a wide range of projects, including: - Analysis of soils, particularly in the assessment of agricultural land and contaminated land - Sorting scrap metal alloys and plastics to increase the value of recyclable materials - Geochemical mapping and exploration to locate mineralisation deposits - Environmental monitoring related to air pollution studies and contamination of the work - The on-line control of industrial processes for the production of raw materials - Archaeological studies and the classification of artefacts, the restoration of sculptures, paintings and other objects of cultural heritage. - In situ geochemical studies on Mars, including the 1997 NASA Pathfinder mission and the forthcoming European Space Agency Mars Express mission, which includes the In these applications, the major advantages of field-portable X-ray fluorescence (FPXRF) spectrometry include: on-site immediate availability of analytical results, non-destructive analysis, a multielement capability, speed of operation and access to valuable/unique samples that otherwise would be unavailable for chemical analysis. The CRP on 'In situ applications of XRF techniques' is one element of the project on Nuclear Instruments for Specific Applications the major objective of which is to assist Member States in the development of nuclear instruments and software for special applications, such as the characterisation of materials. An overall objective of this CRP is to assist laboratories in Member States

    The participants at the second Research Co-ordination Meeting (Vienna, 12-16 August 1991) of the CRP on 'Rapid Instrumental and Separation Methods for Monitoring Radionuclides in Food and Environmental Samples', recommended that a new CRP be established. The current CRP on 'Development and Selection of Analytical Techniques and Procedures for Measuring Accidentally Released Radionuclides in Environment' was established based on this recommendation. The objectives of this CRP are to conduct research and development on applicable methodologies for response to accidental releases, and to improve and maintain the capabilities of the network of laboratories and provide training of individuals within member states. Thus, the CRP serves as a vehicle to maintain contact within the network of laboratories, while developing and transferring analytical techniques and procedures for measuring accidentally released radioactivity. The purpose of the Research Co-ordination Meeting is to discuss the proposed research programs, the status to date and the work planned for the duration of the CRP. The meeting also provides the opportunity for the CRP participants to exchange ideas and possibly develop collaborations in their research. The members of the CRP also need to discuss issues related to the previous CRP on Rapid methods. These include: the preparation of the final report of the previous CRP, the preparation of an addendum to TRS-295 and the ultimate revision or updating of TRS-295. Finally, it is intended that the members of the CRP should discuss the mandate and scope of work of the network of analytical laboratories and the steps needed to firmly establish this network

    The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture through co-ordinated research projects (CRP) supports studies aimed at improving livestock productivity in developing countries through the application of nuclear and related techniques. These studies have focused on animal nutrition, animal reproduction and more recently on animal nutrition/reproduction interactions with emphasis on smallholder farming systems. The primary aim of this CRP was to identify approaches for improving the productivity of dairy cattle maintained on smallholder farms in peri-urban areas. Central to the approach was to first obtain baseline information on productivity and reproductive efficiency and thereby identify nutritional and management constraints. Subsequently, corrective measures were developed and tested, keeping in mind the need for maximising the efficiency of current production systems and sustaining the nutrient supply through practical and economically feasible feed supplementation strategies developed using locally available feed resources. In addition the project envisaged contributing to enhancing the level of expertise within the national animal production research institutes in the region, to encourage close contact and interaction between scientists and institutions in Africa and to promote scientific information exchange on a regional basis. Through the project substantial progress was made in understanding the relationship between nutrient supply and productive and reproductive functions in dairy cattle on smallholder farming systems. Most of the participating countries were able to develop and test cost-effective feed supplementation strategies which improved both milk production and/or reproductive efficiency.

    The Co-ordinated Research Programme (CRP) on Applications of Stable Isotope Tracers in Human Nutrition Research was established by the Agency in October 1988 and was completed in 1992. At various times during this period the CRP encompassed 16 participants in 16 countries. Its general objective was to help establish competence in the use of stable isotope techniques, particularly in developing countries, and particularly with reference to applications of 2 H, 13 C, 15 N, and 18 O in human nutrition research. Thereby it was hoped that it would be possible (i) to identify centres and scientists throughout the developing world who could use stable isotopes in human nutrition research, (ii) to assess the need for methodological adaptations for isotope-based methods in developing countries, and (iii) to advance the competence of the participants in using stable isotopes as tracers of human metabolism. In addition it was expected that the CRP would make a study of some major questions which have been identified by international groups of nutrition experts, particularly in areas relating to energy and protein metabolism. This document comprises copies of the working papers submitted by all CRP participants who contributed a final report on their project. These reports include details of the rationale, methods, results and interpretations from each of the respective studies. Refs, figs and tabs

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

    The aim of this study was to determine if it would be possible to use spinal bone single photon emission computed tomography (SPECT) in patients with unexplained back pain in varied clinical backgrounds and to determine if a positive or negative study had any prognostic value. The study was co-ordinated by the International Atomic Energy Agency (IAEA) and involved 8 centres in 7 countries. A total of 174 patients (mean age 42 years, range 15-80 years) were screened and found to have no obvious cause for their back pain at the time of the SPECT scan. All patients had a CT, and planar radiology. There was clinical follow-up data for 6 months without active treatment (such as surgery) in 147 patients. A panel of 9 specialists in nuclear medicine, radiology and orthopaedics reviewed all images and histories. Final assessment determined that 141 patients had skeletal causes for their back pain. SPECT was abnormal in 64% of these patients as compared to 58% with CT and 18% with planar radiology. CT was most likely to be diagnostic in disc degeneration (sensitivity 92%). SPECT was most diagnostic in facet joint disease (sensitivity 96%). In the 43 patients without any skeletal disease the specificity of SPECT was 79%, compared to 65% for CT. Follow-up of patients at 6 months showed that on average 71% had improvement of symptoms, suggesting a benign course for their back pain, with the exception of patients with pure facet joint disease, identified on SPECT but with no treatment. Spinal skeletal SPECT can be applied in a wide range of social and clinical settings. Results compare well with CT, providing additional information in 30% of patients, especially in facet joint disease where a positive SPECT study, suggests a worse clinical outcome at 6 months.

    In its international role, the IAEA is faced with a wide variety of national situations and different availability of technical, human and financial resources. While it is recognised that nuclear decommissioning is a mature industry in some developed countries, and may soon become a routine activity, the situation is by no means so clear in other countries. In addition, transfer of technologies and know-how from developed to developing countries is not a spontaneous, straightforward process, and will take time and considerable effort. As mandated by its own statute and Member States' requests, the IAEA continues to respond to its Member States by monitoring technological progress, ensuring development of safer and more efficient strategies and fostering international information exchange. Previous co-ordinated research projects (CRP) conducted respectively from 1984 to 1987, and from 1989 to 1993, investigated the overall domain of decommissioning. In those CRPs no distinction was made between decommissioning activities carried out at nuclear power plants, research reactors or nuclear fuel cycle facilities. With technological progress and experience gained, it became clear that decommissioning of research reactors had certain specific characteristics which needed a dedicated approach. In addition, a large number of research reactors reached a state of permanent shutdown in the 1990s and were candidates for prompt decommissioning. With the progressive ageing of research reactors, many more of these units will soon become redundant worldwide and require decommissioning. Within this context, a CRP on Decommissioning Techniques for Research Reactors was launched and conducted by the IAEA from 1997 to 2001 in order to prepare for eventual decommissioning. Concluding reports that summarized the work undertaken under the aegis of the CRP were presented at the third and final Research Co-ordination Meeting held in Kendal, United Kingdom, 14-18 May 2001, and are collected

    Practical application of the sterile insect technique (SIT) against major insect pests will continue to increase as the repeated use of insecticides is recognized as an environmental problem. In the case of the Mediterranean fruit fly (medfly), which attacks over 300 species of fruits and vegetables in tropical, subtropical, and temperate climates on all five continents, control is still largely based on frequent insecticide spraying, often more than 10 sprays per fruiting season. Methods for population estimation, which accurately reflect changes due to movement, mortality or reproduction, are a prerequisite for effective pest management and in particular for use of SIT. With better monitoring tools medfly populations can be estimated more accurately and compared under different conditions, to guide decisions on alternative (i.e. more effective and more environment-friendly) control strategies. In support of this need in the application of SIT field programmes against medfly, an FAO/IAEA co-ordinated research project (CRP) was carried out which resulted in a TECDOC published in 1996 on Standardization of Medfly Trapping for Use in sterile insect technique Programmes. Following the development of male only genetic sexing strains at the FAO/IAEA Agriculture and Biotechnology Laboratories in Seibersdorf, Austria, it was recognized that the development of a female medfly targeted trapping system, in conjunction with only male sterile releases, would improve the efficacy of the SIT, reduce costs, and more effectively utilize sterile males. As a result, a new FAO/IAEA Co-ordinated Research Project on Development of Female Medfly Attractant Systems for Trapping and Sterility Assessment was initiated in 1994 with the objective to develop new synthetic female medfly attractants and to determine their efficacy compared to proteinaceous baits under different weather, host-tree and population density conditions. Findings obtained during the course of this 5-year CRP are

    Practical application of the sterile insect technique (SIT) against major insect pests will continue to increase as the repeated use of insecticides is recognized as an environmental problem. In the case of the Mediterranean fruit fly (medfly), which attacks over 300 species of fruits and vegetables in tropical, subtropical, and temperate climates on all five continents, control is still largely based on frequent insecticide spraying, often more than 10 sprays per fruiting season. Methods for population estimation, which accurately reflect changes due to movement, mortality or reproduction, are a prerequisite for effective pest management and in particular for use of SIT. With better monitoring tools medfly populations can be estimated more accurately and compared under different conditions, to guide decisions on alternative (i.e. more effective and more environment-friendly) control strategies. In support of this need in the application of SIT field programmes against medfly, an FAO/IAEA co-ordinated research project (CRP) was carried out which resulted in a TECDOC published in 1996 on Standardization of Medfly Trapping for Use in sterile insect technique Programmes. Following the development of male only genetic sexing strains at the FAO/IAEA Agriculture and Biotechnology Laboratories in Seibersdorf, Austria, it was recognized that the development of a female medfly targeted trapping system, in conjunction with only male sterile releases, would improve the efficacy of the SIT, reduce costs, and more effectively utilize sterile males. As a result, a new FAO/IAEA Co-ordinated Research Project on Development of Female Medfly Attractant Systems for Trapping and Sterility Assessment was initiated in 1994 with the objective to develop new synthetic female medfly attractants and to determine their efficacy compared to proteinaceous baits under different weather, host-tree and population density conditions. Findings obtained during the course of this 5-year CRP are

  12. Alternative technologies for 99Tcm generators. Final report of a co-ordinated research programme 1990-1994

    International Nuclear Information System (INIS)

    1995-12-01

    99 Tc m is the workhorse of nuclear medicine and currently accounts for over 80% of all in vivo diagnostic procedures. This radionuclide is made available to nuclear medicine centers in the form of a generator wherein the parent 99 Mo (generally produced by the fission of 235 U) is retained on a column of alumina and the daughter 99 Tc m produced by the decay of 99 Mo is separated out by elution of the column with saline solution. Fission 99 Mo is now routinely produced only in a few large production centers in the world and the short half-life of 99 Mo poses transportation problems. Recognizing the need to develop alternative technologies for the production of 99 Tc m generators in developing Member States operating medium neutron flux research reactors, the IAEA initiated a co-ordinated research programme (CRP) in 1983. As a result of the work carried out under the auspices of this CRP (1983-1989), it became apparent that technologies based on low temperature sublimation processes and polymolybade gels showed excellent potential for the preparation of reliable and economical 99 Tc m generators. Generators based on elution of polymolybade gels have since been developed and evaluated. Further, based on their own research work and publication from other sources, the experts who participated in this CRP have made a detailed evaluation of other possible alternative technologies for the production of 99 Tc m generators using 99 Mo produced by the non-fission route. 24 refs, 16 figs

    Since the beginning of the joint FAO/IAEA programme on the research and development of insect pest control methodology, emphasis has been placed on the basic and applied aspects of implementing the sterile insect technique (SIT). Special emphasis has always been directed at the assembly of technological progress into workable systems that can be implemented in developing countries. The general intention is to solve problems associated with insect pests that have an adverse impact on production of food and fibre. For several insect species SIT has proven to be a powerful method for control. This includes the New World screwworm fly (Cochliomyia hominivorox), the Mediterranean fruit fly (Ceratitis capitata), the melon fly (Bactrocera cucurbitae), the Queensland fruit fly (Bactrocera tryoni) and one tsetse fly species (Glossina austeni). Improvements of the SIT are possible, especially through the use of molecular techniques. The final report of the Co-ordinated Research Programme on ``Genetic Engineering Technology for the Improvement of the Sterile Insect Technique`` highlights the progress made towards the development of transformation systems for non-drosophilid insects and the research aimed at the identification and engineering of potential target genes or traits.

    The FAO/IAEA Co-ordinated Research Project has brought together sesame breeders from 11 countries. They, together with pathologists, agronomists and physiologists, have made considerable effort to advance the genetic improvement in sesame. The results and conclusions from this project cover the mutation techniques used for the genetic improvement of various aspects of sesame. These recommendations do not only deal with the application of mutation induction, but also with the wider plant breeding related objectives and methods to be considered for this semi-domesticated crop. It is clear that more advanced techniques can and should be incorporated in the process which would enhance the genetic improvement. Although five years is a relatively limited time in a plant breeding programme, the participants have been able to produce and make available a considerable pool of agronomically interesting mutant sesame germplasm. The participants in the CRP considered that, together with other specialists, plant breeders can gain fuller benefit from the mutations induced by radiation or chemicals. Work on these mutants must continue in co-operation/consultation with plant physiologists and pathologists, and with biotechnologists who may in the future be able to provide in the future methods for introducing beneficial traits from other crops into sesame. The sesame programme should include scientists from the Member States where sesame grows and scientists from developed countries who may have greater access to physiological and molecular research facilities.

    The isotopic composition and chemical constituents of water infiltrating through the soil zone (unsaturated zone, or zone of aeration) into groundwater can be employed to determine the moisture transport in the unsaturated zone, thus enabling estimation of the water infiltration rate to the underlying aquifer. This was the basis on which this CRP was initiated in 1996. The overall results obtained from three years of applied field research related to study of moisture transport dynamics and estimation of natural recharge through use of isotope/hydrochemical depth profiles of the soil moisture in the unsaturated zone were presented and discussed at the final Research Co-ordination Meeting held in Vienna from 18 to 21 October 1999. A total of 44 sites were involved in the project on which detailed information on physiography, lithology, rainfall, unsaturated moisture content and a variety of chemical and isotopic determinants is now available. This publication contains 11 individual reports presented by CRP participants at the Meeting. Each of the reports have been indexed separately

    The Co-ordinated Research Project (CRP) on Radiotracer Technology for Engineering Unit Operation Studies and Unit Process Optimization was carried out by the International Atomic Energy Agency (IAEA) from December 1997 until December 2000. The project developed and validated procedures and protocols for investigation of major industrial processes, including fluidized beds, sugar crystallizers, trickle bed reactors, cement rotary kilns, flotation cells, grinding mills, incinerators, wastewater treatment units and interwell communications in oil fields. This publication is the output of the above mentioned CRP. It provides the principles and state of the art of radiotracer methodology and technology as applied to industry and environment. It is expected to provide wider interest for further development of skills and confidence prior to carrying out field work. It facilitates transfer of technology from developed to developing countries and from nuclear research institutions to industrial end users. The publication could be a suitable guide for radiotracer applications in almost all types of process investigations. The case studies described in this publication deal with typical problems in industry and environment common to all countries. It is intended for radiotracer groups as well as for end engineers and managers from chemical and petrochemical industries, mineral ore and raw material processing, wastewater treatment plants, and other industrial sectors

    Poor bone health is a major public health problem of worldwide concern. It affects all segments of the population, but is particularly important in older people (and, most of all, in post-menopausal women). In view of the fat that the numbers of older people, both in absolute terms and as a fraction of the total population, are increasing practically everywhere, there is little doubt that poor bone health will become a much more widespread and severe problem in coming decades. Earlier in 1994 the International Atomic Energy Agency (henceforth ``the Agency``) started a 5-year Co-ordinated Research Programme (CRP) based on the recommendations of an Advisory Group Meeting (AGM) held in 1992. This CRP currently addresses on particular measure of bone health -bone mineral density (BMD). The main concept underpinning this CRP is the ideal that a major determinant of bone health in later years is peak bone mass. The objective of the Agency`s CRP is to determine the age of peak bone mass in various different study groups and countries, and to investigate how BMD varies with age, sex, ethnicity and geographical origin of the subjects. Information on individual participant`s plans for implementation of the CRP, and progress achieved so far on this and related topics, was presented in each country`s report. Refs, figs, tabs.

    The International Atomic Agency (IAEA) has initiated a new Co-ordinated Research Programme (CRP) on Hydrogen and hydride induced degradation of the mechanical and physical properties of Zirconium-based alloys. In the first phase of this CRP the methodology for measuring the velocity of Delayed Hydride Cracking (DHC) should be established and participating laboratories from about nine countries around the world carry out identical tests in 'round robin'. The objective of the present work is to establish at Studsvik laboratory the method of a constant load cracking test on unirradiated Zr-2.5Nb and attain a comparison of results between laboratories. Constant load tests are performed on specimens cut from unirradiated CANDU Zr-2.5Nb pressure tube and the rate of crack propagation is determined in each test. Pre-hydrided specimens for testing are supplied from the host laboratory. Six specimens have been tested for delayed hydride cracking (DHC) at 250 deg C. The axial crack growth velocities measured in the tests are within the interval of 8.62x10 -8 - 1.06x10 -7 m/s. The results obtained agree well with the earlier published data for similar materials and test conditions

    A Co-ordinated Research Project (CRP) on Software Utilities for Gamma Ray Spectrometry was initiated by the International Atomic Energy Agency in 1996 for a three year period. In the CRP several basic applications of nuclear data handling were assayed which also dealt with the development of PC computer codes for various spectrometric purposes. The CRP produced several software packages: for the analysis of low level NaI spectra; user controlled analysis of gamma ray spectra from HPGe detectors; a set of routines for the definition of the detector resolution function and for the unfolding of experimental annihilation spectra; a program for the generation of gamma ray libraries for specific applications; a program to calculate true coincidence corrections; a program to calculate full-energy peak efficiency calibration curve for homogenous cylindrical sample geometries including self-attenuation correction; and a program for the library driven analysis of gamma ray spectra and for the quantification of radionuclide content in samples. In addition, the CRP addressed problems of the analysis of naturally occurring radioactive soil material gamma ray spectra, questions of quality assurance and quality control in gamma ray spectrometry, and verification of the expert system SHAMAN for the analysis of air filter spectra obtained within the framework of the Comprehensive Nuclear Test Ban Treaty. This TECDOC contains 10 presentations delivered at the meeting with the description of the software developed. Each of the papers has been indexed separately

    This Co-ordinated Research Project (CRP) addresses an important public health issue in many developing areas, which is the existence of high rates of infection and diarrhoea disease and its deleterious effects on the health and nutritional status of infants and children around the world. Persistent diarrhoea with associated malnutrition remains a major cause of morbidity and mortality in the developing countries. There are established relations between diarrhoea disease and Helicobacter pylori infection and the latter may also additionally specifically impair nutrient absorption. Helicobacter pylori infection is likely to be the most common world wide bacterial infection, and it is estimated that approximately 50% of the general population is affected. The World Health Organisation has classified H. pylori as a Group 1 carcinogen. Young children in developing countries are the main targets of infection, with a substantial risk of developing gastric carcinoma during adulthood. High infection rates of H. pylori among new-borns and young children in developing nations appear to be a major cause for chronic under-nutrition and diarrhoea syndrome with failure to thrive. This bacterium can survive in the acidic interior of the human stomach due to its capacity to secrete an enzyme called urease, which decomposes the urea contained in the stomach's interior into ammonia and carbon dioxide increasing the pH move underneath the protective mucous membrane in the stomach where it is protected from the caustic stomach acid. This transitory drop in stomach acidity, explained by a diminished gastric secretion and an increase in ammonia production during infection, promotes the transit of lower bowel pathogens leading to repeated gastrointestinal infections, causing diarrhoea and adverse consequences on nutrition and growth. This CRP seeks to identify and assist research groups in developing countries, which plan to conduct studies on the area of H. pylori infection and its

    Radioisotopes produced with a cyclotron and their corresponding radiopharmaceuticals have already been shown to be extremely valuable in basic medical research, disease diagnosis and radiotherapy treatment. There are more than 200 cyclotron facilities worldwide and the number is growing every year. A number of the Member States have acquired cyclotrons for the purpose of producing radioisotopes for nuclear medicine and a number of others have expressed an interest in acquiring such facilities. This report is concerned with the production of four radiotracers: Iodine-123, Iodine-124, Thallium-201 and Palladium-103. Iodine-123 is already widely used in SPECT studies, I-124 has shown great promise and can be used for PET studies as well as in radiotherapy. Tl-201 is widely used throughout the world as 201 Tl + for measuring cardiac blood flow. It is a routine tool that is needed for the Nuclear Medicine communities and can be made available by those countries possessing a cyclotron facility with 30 MeV protons. Moreover, as preliminary results dealing with the labelling of chelated polypeptides with trivalent cationic Tl-201 are very promising; the nuclide can also be tried as a potential substitute for Indium tracers in SPECT diagnosis involving polypeptides. Palladium-103, an Auger electron emitter, has become an extremely important radionuclide for therapy. The Co-ordinated Research Programme (CRP) focuses on the optimisation and standardisation of solid phase cyclotron target technology for the production of I-123, I-124, Tl-201 and Pd-103. In particular, as originally proposed and further discussed and agreed upon during the 1st Research Co-ordination Meeting, the main technical goals of the CRP are described as follows: (i) to investigate the possibility of using electrodeposited tellurium and melted tellurium oxide as target material for the production of I-123 and I-124. For the oxide target, the following parameters and techniques will be explored: 1) methods

    The strengths and weaknesses of population education programs in Sri Lanka, Nepal, and the Maldives, based on descriptive research studies, are identified. The research topics were devised at a Subregional Meeting on Joint Research studies in Population Education for South Asia Subregion in 1990, as well as motivational strategies for promoting the small family norm in Bangladesh and Pakistan. Results were presented at a 1991 meeting held in UNESCO PROAP. The results were that 3 very different collaborative modalities operate in these countries. Sri Lanka had a formal national population committee for coordinating functions. The Maldives had no national formal structures, but there were linkages between population programs. Nepal had a formal structure but had failures in coordination. The Sri Lanka Population Committee, which began in 1972, established population education when the entire educational system was being reformed. The curriculum development committee consisted of representatives from a variety of disciplines and worked as a cohesive unit. As a consequence, junior secondary schools taught population education in such courses as social studies and science. Regional departments of education provided inservice training to the junior secondary school teachers. At the policy level, the education plan of 1972/73-77 was implemented within the National 5 Year Plan and the Population Committee functioned under a senior government Minister, which provided greater credibility and implementation. It also ensured linkage with other departments, agencies, and development programs. In the Maldives, the linkage was between the Population Education Program of the Educational Development Center (EDC) and the Allied Health Service Training Center's (AHSTC) child-spacing program. The small scale size may be a factor in the coordination and resource sharing and effective linkages without a formal national committee umbrella. The weakness was in multiplicity of effort

The primary objective of this CRP was to breed improved varieties of stable food crops of Africa with the main emphasis on the indigenous species and their local cultivars. The fourth and final Research Co-ordination meeting under the CRP was held in Naples, Italy from 30 October - 3 November 1995. This publication includes the reports, conclusions and recommendations made by the participants. We hope that it will be of value to researchers, students and policy makers alike in their endeavour to promote plant breeding and increase food productions in Africa. Refs, figs, tabs

    The contributions presented in this technical publication describe progress in understanding and controlling the degradation of polymeric materials induced by exposure to ionizing radiation. This subject area is of widespread importance to industrial use of radiation for two classes of applications: (1) the processing and production of polymeric materials by means of irradiation facilities, and (2) the use of polymeric materials in applications for which they must withstand irradiation throughout the course of their useful lifetimes. Due to extensive and still-growing use of polymeric materials for technological applications of immense variety, and the fact that radiation-processing has the potential to play an expanding role in polymer manufacturing (current uses include crosslinking, curing, sterilization, surface modification, lithography, etc.), the ability to inhibit unwanted material property changes which often occur when materials are irradiated, and to predict useful lifetimes, remains a limiting factor in a number of existing radiation technologies. Additionally, the ability to control unwanted degradation will be necessary for successful implementation of future, more advanced, radiation processing schemes. This co-ordinated research project (CRP) was established for the purpose of focusing the attention of appropriate technical experts on the complex task of establishing a better fundamental basis for understanding and attacking problems or radiation degradation of materials. The group dynamics have been designed to achieve a synergistic interaction among worldwide research facilities for the purposes of identifying degradation problems, exchanging ideas and results on the solution of these problems, and making the emerging information available in an organized and accessible format. From this meeting, it is clear that much remains to be learnt in terms of understanding degradation mechanisms and phenomena. It also appears that important new

    The International Atomic Energy Agency (IAEA) prepares regulations for the safe transport of radioactive material, and periodically revised editions of these are published. These regulations are adopted by individual countries across the world and by international organisations concerned with transport. Whilst it is desirable to have a stable framework of regulatory requirements, there is also a need to take account of technical advances and operational experience and revise the regulations. From time to time Co-ordinated Research Programmes (CRP) are established to investigate particular areas of the regulations that are giving concern. In 1996 the IAEA Standing Advisory Group on the Transport of Radioactive Material (SAGSTRAM) concluded that the requirements for classification, packaging and transport of low specific activity (LSA) material and surface contaminated objects (SCO) did not always have a strong radiation protection basis. Accordingly SAGSTRAM established a CRP with an overall objective to develop a dose-based approach for establishing LSA/SCO requirements. Six countries are participating in this CRP. Brazil, Canada, France, Germany, United Kingdom and United States. Each country is carrying out work that is outlined in agreements with the IAEA, with the work aimed at meeting the specific objective of the agreement and also contributing to achieving the overall objective of the CRP. Completion of the CRP usually involves the preparation of an IAEA TECDOC by a Consultant Services Meeting (CSM), and this TECDOC will summarise the work performed under the CRP and include any recommendations made by the CRP. Following the establishment of the CRP in 1997, the first Research Co-ordination Meeting (RCM) was held in December 1997. The second RCM was held in March 1999, with the final RCM planned for the end of 2000. The work being carried out by Brazil and Canada is focused upon the transport of uranium and thorium ores, and is a mixture of theoretical and

    The principle of wall thickness measurement and monitoring of corrosion and deposits by means of film-based tangential projection radiography is known since decades. Nevertheless, there are no international standards and guidelines available. The International Atomic Energy Agency has organized a co-ordinated research programme bringing together participants from twelve member states to study the state of the art. The general scope of the project covered radiographic inspection of corrosion and deposits in steel pipes (diameter >150mm) corroded on the outer or inner surfaces with or without insulation. Two inspection methods have been investigated: 1. tangential radiographic projection technique (TRT) and 2. double wall inspection technique (DWT). The application ranges of both methods were studied depending on pipe diameter, wall thickness, radiation source (X-ray, Ir-192 and Co-60 were used) and screen/film combination. Diagrams for application limits using TRT have been designed and verified by the participating countries. All measurements have been performed on special designed test pieces and also industrial pipes. Corrosion measurements based on DWT are more sophisticated and use effective attenuation coefficients to calculate wall thickness changes from density differences shown on the film. The values of effective attenuation coefficients, established for Ir-192 and Co-60, are stable and independent in a wide range on pipe diameter and insulation. Guidelines were developed and tested in the twelve different countries to determine the reliability of this technology. A testing procedure approved by the project partners has been released and shall be submitted as standard proposal. (orig.)

    Low and intermediate level radioactive waste is generated from the use of radioactive materials in industrial applications, research and medicine. The waste management programmes and activities in many developing Member States have been reviewed through a Waste Management Advisory Programme (WAMAP) implemented by the IAEA in 1987-1995. One of the WAMAP objectives was to assist in practical development and implementation of safe and efficient waste treatment methods. In this context the IAEA has initiated a co-ordinated research programme on treatment technologies for institutional wastes covering the most important recurring problems in developing Member States. The programme was intended to cover the research and development required for reliable waste treatment operations, including the likely variations in institutional waste inputs using simple low cost processes. This co-ordinated research programme was initiated in 1991 and brought together 14 participants from 13 countries. The results of the studies were discussed at three research co-ordination meetings. This report summarizes the salient features and results obtained during five year investigations and provides recommendations for future work in this area. Refs, figs, tabs.

    The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated a Co-ordinated Research Project on The Use of Isotopes in Studies to Improve Yield and N 2 Fixation of Grain Legumes with the Aim of Increasing Food Production and Saving N-fertilizer in the Tropics and Sub-Tropics of Asia that was operational from 1990 to 1995. This Project was underpinned by extensive experience in the use of 15 N-labelled fertilizer in quantifying N 2 fixation by food and pasture legumes; the isotope-dilution technique, recognized as the most accurate mode of quantifying fixation, was developed at the IAEA and has been used profitably for over 20 years in co-ordinated research projects that were focused on aspects relevant to the sustainability of agriculture in developing countries in which food security is most under threat. This effort to improve N 2 fixation by food legumes in Asia, and in so doing to increase productivity of cereal-based farming systems as a whole, was timely in terms of regional needs. It was complemented by an overlapping Co-ordinated Research Project entitled ''The Use of Nuclear and Related Techniques in Management of Nitrogen Fixation by trees for Enhancing Soil Fertility and Soil Conservation in Fragile Tropical Soils''.

    Sesame (Sesamum indicum L.) is an ancient oil crop considered to be still at an early stage in breeding. The fact that sesame is a crop of mainly developing countries with limited available research funds for long term breeding programmes, resulted in very few breeding efforts in research stations. Furthermore, sesame is not a mandate crop of any of the international agriculture research centers. Until recently most of the released sesame varieties in countries such as China, India and the Republic of Korea were the product of selection and pedigree breeding. A major constraint in this approach was the lack of sufficient genetic variation within the existing germplasm collections, especially for traits such as resistance to various diseases and seed retention. This is where mutation techniques could offer a possible solution. The United Nations Food and Agriculture Organization (FAO) organized some expert consultations on sesame breeding between 1981 and 1987, which all recommended the use of mutation induction for the enhancement of genetic variability with a focus on the following traits: modified plant architecture, seed retention, and resistance to diseases and pests. As a result, most of these recommendations have been included in this five year co-ordinated research project (CRP) that started in 1993, organized by the Plant Breeding and Genetics Section of the Joint FAO/IAEA Division. This CRP focused on the induction of the above mentioned characters in different sesame improvement programmes, and on the enhancement of co-operation between sesame breeders in developed and developing countries. Each participant covered a number of traits important for their specific breeding needs. During regular meetings under this project the participants had the opportunity to jointly appraise and evaluate sesame mutants and varieties in demonstration fields, thus strengthening the mutual effort for the genetic improvement of sesame through mutation techniques.

    This publication results from the second FAO/IAEA Research Co-ordination Project (CRP) on Inherited Sterility in Lepidoptera (caterpillars of moths). The present CRP and a previous one entitled 'Radiation Induced F{sub 1} Sterility in Lepidoptera for Area-Wide Control' were initiated in response to requests from Member States for the development of environment friendly alternatives to current control of moth pests. The first five-year CRP (1987-1991) dealt primarily with aspects such as determining the effects of various radiation dose levels on the resulting sterility in the treated parents and their F{sub 1} progeny in different Lepidoptera species. In addition, models were developed on the suppressive effects of F{sub 1} sterility on field populations, and some studies were conducted in laboratory or field cages to assess the impact of inherited sterility on pest suppression. The research results were published in 1993 in the IAEA Panel Proceedings Series. This follow-up CRP (1994-1998) has built on the results of the first CRP and has focused on addressing a more challenging phase, consisting of rearing key pest moths and evaluating their application for pest control purposes. The specific objective of the CRP was therefore to assess the potential of suppressing populations of caterpillar pests in the field by inherited sterility methods, i.e. by rearing and releasing irradiated moths and/or their progeny in combination with other biological control methods. The ultimate goal is to have alternative environment-friendly control methods available to be able to reduce the vast quantities of insecticide that are used in agriculture to combat Lepidoptera pests and that adversely affect the trade balance of developing countries because they must use hard currency to import them. The two FAO/IAEA sponsored Lepidoptera CRPs have resulted in expanded research and implementation programmes on F{sub 1} sterility in combination with natural enemies. Such programmes are

    Malignant tumour disease accounts for approximately one third of deaths worldwide. Gastrointestinal adenocarcinomas, prostate and breast cancers are among the most frequently appearing tumours. Radiotherapy is an essential mode of treatment of all cancer patients either alone or in conjunction with other modalities like surgery and chemotherapy. In most cases radiotherapy is given using external radiation sources. It is also possible to administer radiotherapy by specifically localizing radioisotopes emitting particulate radiation in the tumour tissue. This targeted therapy has proved to have several advantages over external beam therapy, notably the possibility of selectively delivering higher radiation doses to the targeted tumour cells and treating multiple metastases. Procedures for therapy of thyroid carcinoma and hyper-thyroidism using radioiodine (131I) introduced about five decades ago, have stood the test of time and are still widely used the world over. In addition to the therapeutic nuclides of the first generation 131I, 89Sr, 32P, 90Y, etc., which are still widely utilized and accepted by the medical community, many other beta emitting radionuclides with relatively short half-lives such as 153Sm, 186Re, 188Re, 166Ho, 165Dy, etc. have also been recently made available for therapy and used with promising good results. In spite of the potential of targeted radiotherapy to treat a wide range of malignant conditions, routine clinical use is mostly confined to therapy of thyroid carcinoma, hyperthyroidism, metastatic bone pain and synovectomy. In most of the cases, the limitation is obviously not the availability of suitable radionuclides but rather the lack of suitable carrier molecules that would adequately concentrate these radionuclides in target tissues of interest. Based on the above considerations, the scope of the Co-ordinated Research Project (CRP) has focused on the synthesis of the required BFCAs for MoAbs and peptide labelling, development and

    Fission product yields are required at several stages of the nuclear fuel cycle and are therefore included in all large international data files for reactor calculations and related applications. Such files are maintained and disseminated by the Nuclear Data Section of the IAEA as a member of an international data centres network. Users of these data are from the fields of reactor design and operation, waste management and nuclear materials safeguards, all of which are essential parts of the IAEA programme. In the 1980s, the number of measured fission yields increased so drastically that the manpower available for evaluating them to meet specific user needs was insufficient. To cope with this task, it was concluded in several meetings on fission product nuclear data, some of them convened by the IAEA, that international co-operation was required, and an IAEA co-ordinated research project (CRP) was recommended. This recommendation was endorsed by the International Nuclear Data Committee, an advisory body for the nuclear data programme of the IAEA. As a consequence, the CRP on the Compilation and Evaluation of Fission Yield Nuclear Data was initiated in 1991, after its scope, objectives and tasks had been defined by a preparatory meeting. The different tasks, such as special evaluations and development of improved methods, were distributed among participants. The results of the research work were discussed and approved by all participants in research co-ordination meetings. For a successful development of theoretical and empirical models, experiments had to be recommended and their results to be awaited, which made necessary an extension of the CRP by two years.

  3. Standardized methods to verify absorbed dose in irradiated food for insect control. Proceedings of a final research co-ordination meeting

    International Nuclear Information System (INIS)

    2001-03-01

    Irradiation to control insect infestation of food is increasingly accepted and applied, especially as a phytosanitary treatment of food as an alternative to fumigation. However, unlike other processes for insect control, irradiation does not always result in immediate insect death. Thus, it is conceivable that fresh and dried fruits and tree nuts, which have been correctly irradiated to meet insect disinfestation/quarantine requirements, may still contain live insects at the time of importation. There is, however, a movement by plant quarantine authorities away from inspecting to ensure the absence of live insects in imported consignments towards examining through administrative procedures that a treatment required by law has been given. Nevertheless, there is a need to provide plant quarantine inspectors with a reliable objective method to verify that a minimum absorbed dose of radiation was given to supplement administrative procedures. Such an objective method is expected to bolster the confidence of the inspectors in clearing the consignment without delay and to facilitate trade in irradiated commodities. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated a co-ordinated research project (CRP) in 1994 to generate data on the verification of absorbed dose of irradiation in fresh, dried fruits and tree nuts for insect disinfestation/quarantine purposes. A standardized label dose indicator available commercially was used to verify the minimum/maximum absorbed dose of the irradiated commodities for these purposes as required by regulations in certain countries. It appears that such a label dose indicator with certain modifications could be made available to assist national authorities and the food industry to verify the absorbed dose of irradiation to facilitate trade in such irradiated commodities. This TECDOC reports on the accomplishments of this co-ordinated research project and includes the papers presented by the participants

    International Nuclear Information System (INIS)

    1989-09-01

    Concern about the release of radionuclides to the environment, especially to the foodchain, has been heightened by recent nuclear incidents. The assessment of any release of radioactivity demands rapid, reliable and practical techniques. In the intermediate and late post-accident period, where the interest is in food control rather then evacuation and sheltering, rapid methods would be useful for screening purposes as well as providing timely information and easing sample workload minimizing sample overloads. In the first research co-ordination meeting on the co-ordinated research program ''Rapid.... samples'', the specifications for the time required for sample preparation, separation, and analysis and the accuracy desired were outlined. Considerable attention was given to the need to develop rapid method for sample preparation and dissolution. Emphasis was placed on achieving the development of rapid methods with the minimum sacrifice in reliability, practicality and economy

    In 1994, the International Atomic Energy Agency started the five-year Co-ordinated Research Project (CRP) on Comparative International Studies of Osteoporosis Using Isotope Techniques. The objectives of this study were: To harmonize the techniques of measuring BMD within the participating countries and to obtain data that can be compared between the different study groups (countries); To determine whether early adult PBM varies between populations over the age range from 15 to 50 years. In other words, to determine the age of peak bone mass in selected populations from developing countries; To explore environmental and nutritional contributions to any determined differences. Further information about the purpose and scope of the CRP may be found in the report of the Advisory Group Meeting (AGM) held in 19921 and other reports of this CRP. Since the last RCM held in 1998, the CRP participants have gathered up more data on BMD. Indeed 3488 subjects 15-50 years) have been recruited for the purpose of this project and have been stratified equally by sex and age into six -year age bands. Most of the participants have also completed collecting data on dietary intake, medical history, physical exercise, and lifestyle, as suggested in the VrHO questionnaire. Some participants have analyzed trace elements in a number of bone samples as well. One of the most important purposes of this CRP is to obtain harmonized data on BMD that is comparable from one study group to another. To ensure this quality insurance, the densitometers in each center were cross calibrated using a European Spine Phantom (ESP). Further-more, day-to-day control of DEXA machines was managed by each individual center. The fourth Research Co-ordination Meeting (RCM) for participants of the CRP, which is the subject of the present report, was held at the University of Sheffield Medical School; WHO Collaborating Center for Metabolic Bone Diseases in Sheffield, UK from 28 Feb. to 3 March 2000

  10. New methods and techniques for decontamination in maintenance or decommissioning operations. Results of a co-ordinated research programme 1994-1998

    International Nuclear Information System (INIS)

    1998-06-01

    Decontamination of nuclear facilities is a subject of increasing importance as the nuclear community considers the issues related to the decommissioning of surplus or obsolete facilities and making modifications to operational facilities, or conducts the necessary inspections and maintenance to permit continued efficient and safe operation of existing facilities. Previous co-ordinated research programmes (CRP) conducted respectively from 1984 to 1987, and from 1989 to 1993, highlighted the role of decontamination within the overall domain of decommissioning. Having recognized technological progress in decontamination and the large potential for optimization, the CRP on New Methods and Techniques for Optimization of Decontamination for Maintenance or Decommissioning was launched and conducted by the IAEA from 1994 to 1998. Concluding reports that summarized the work undertaken under the aegis of the CRP were presented at the third and final Research Co-ordination Meeting (RCM) held in Mol, Belgium, 12-16 January 1998 and are collected in this Technical Document. Operating experience in real-scale applications, lessons learned, key results in laboratory scale or pilot scale research, and validation of mathematical models, are among the most significant achievements of the CRP and have been highlighted

    In the developed countries, research using nuclear methods has been substantially used to examine the physiological and biochemical mechanisms involved in obesity-related diseases. This Co-ordinated Research Project (CRP) is intended to promote the use of these techniques in the developing world. The specific objectives of this CRP are: 1. To define the magnitude of the obesity/NIDDM problem in developing countries. 2. To identify vulnerable groups at high risk. 3. To describe the metabolic mechanisms involved. The purpose of this first Research Co-ordination Meeting (RCM) was thus to develop a worldwide collaboration in the use of nuclear and isotopic techniques to investigate the aetiology of degenerative diseases in ageing. All countries participating in this CRP are going through the epidemiological transition with changes in lifestyles to approach those seen in the developed nations. This first meeting was held in the Agency's headquarters in Vienna, with participation of contract and agreement holders, experts, observer, and in-house staff.

  12. Review of methodologies for analysis of safety incidents at NPPs. Final report of a co-ordinated research project 1998-2001

    International Nuclear Information System (INIS)

    2002-03-01

    The safe operation of nuclear power plants around the world and the prevention of incidents in these installations remain key concerns for the nuclear community. In this connection, the feedback of operating experience plays a major role: every nuclear power plant or nuclear utility needs to have a system in place for collecting information on unusual events, whether these are incidents or merely deviations from normal operation. Reporting to the regulatory body of important events and lessons learned is normally carried out through the national reporting schemes based on regulatory reporting requirements. The most important lessons learned are further shared internationally, through, for example, the Joint IAEA/NEA Incident Reporting System (IRS) or the event information exchange of the World Association of Nuclear Operators (WANO). In order to properly assess the event, an adequate event investigation methodology has to be applied, which leads to the identification of correct root causes. Once these root causes have been ascertained, appropriate corrective actions can be established and corresponding lessons can be drawn. The overall goal of root cause analysis is the prevention of events or their recurrence and thus the overall improvement in plant safety. In 1998, the IAEA established a co-ordinated research project with the objective of exploring root cause methodologies and techniques currently in use in Member States, evaluating their strengths and limitations and developing criteria for appropriate event investigation methodologies. This report is the outcome of four years of co-ordinated research which involved 15 national and international research organizations

    A co-ordinated research programme on the Application of Isotopic Correlation Techniques (ICT) to International Safeguards has just ended in the Agency. During the continuation of the programme, scientists from Belgium, Japan, France, United Kingdom, United States and Euratom, engaged in the development of ICT, met periodically to discuss the results obtained by them from both theoretical and experimental investigations. The paper describes the main features of the alternative approaches developed at participating laboratories as well as procedures developed at the IAEA. At the conclusion of the programme, there was an unanimous recommendation from the participants that ICT is a useful tool for verification of input analysis at a chemical reprocessing plant. After the closure of the co-ordinated research programme, the IAEA is now applying data evaluation procedures developed at the Agency and keeping in contact with the progress of work on ICT carried on in laboratories such as JAERI (Japan), CEA (France) and Euratom, through support programmes and through participation in the ESARDA working group dealing with ICT

    In the last ten years, geothermal energy has emerged as an alternative source of energy for electrical and non-electrical uses. In some of these countries geothermal energy contributed up to 40% of the national power requirement. In others, it is being widely used in agriculture, aquaculture, air conditioning, kiln and fruit drying, pulp and paper industry, greenhouses and food processing. The Co-ordinated Research Programme (CRP) on the Application of Isotope and Geochemical Techniques to Geothermal Exploration in the Middle East, Asia, the Pacific and Africa aimed at integrating isotope techniques with traditional geochemical and hydrological methods in understanding the characteristics of geothermal systems. It involved isotopic and chemical surveys of hot to cold springs, wells and rivers in exploration areas as well as in exploited reservoirs where problems such as return of injected wastewaters are experienced. This publication is a compilation of the scientific papers presented at the final Research Co-ordination Meeting, held in Dumaguete City, Philippines, from 12 to 15 October 1993.

    A co-ordinated research programme on the use of nuclear and nuclear-related techniques in the study of environmental pollution associated with solid wastes was started by the Agency in December 1987 and now comprises nineteen participants from seventeen countries. Topics of interest in this programme include studies of atmospheric aerosols, coal fly ash, incinerator ash, sewage sludge and a variety of other environmental specimens contaminated with solid wastes. The analytical techniques being used in this programme include neutron activation analysis (NAA), particle induced X-ray emission (PIXE) and energy-dispersive X-ray fluorescence (ED-XRF). This report summarizes the discussions that took place during the first research co-ordination meeting. Working papers presented by the participants are included as annexes. The main outcome of the meeting was agreement to include a ''core'' programme comprising studies of (1) aerosols collected from areas of low and high pollution, (2) coal fly ash composition, and (3) leaching of toxic elements from coal fly ash

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

    Herbicide products as sold to the user are a mixture or formulation of active ingredient, surfactants and other adjuvants, plus a carrier, which will be a liquid if the formulation is to be applied as a spray. The adjuvants affect the characteristics of the spray, including the retention of the droplets by plant surfaces and the penetration of active ingredient into the plant. Thus they play a critical part in determining the phototoxicity and selectivity of the product. The IAEA organized a co-ordinated research programme in 1992 to explore the possibility of improving the performance of the herbicide glyphosate on Cyperus rotundus (purple nutsedge), commonly regarded as the ``world`s worst weed``, by modifying the commercial formulation using penetration studies with {sup 14}C labelled glyphosate as the initial screening procedure. This TECDOC summarizes the outcome of the programme and includes the papers presented at the research co-ordination meeting held in Los Banos, Philippines, 17-21 February 1997.

    International Nuclear Information System (INIS)

    2002-07-01

    Aquifer systems in most urban areas have been impacted to varying degrees by sustained exploitation and the future availability of water is being threatened by depleting aquifers or water quality degradation. Improved methods for the assessment and management of groundwater resources in major urban areas, therefore, are issues of high priority for most countries. The IAEA has, over last four decades, co-ordinated the development, adaptation, and testing of isotope techniques for hydrological applications. A number of techniques and methodologies that are now established for water resources management are potentially useful for characterizing the short and long term changes resulting from the extensive use of aquifers in and near urban areas. The application of isotope techniques in urban hydrology was the focus of this co-ordinated research project (CRP). This report provides the final results of the CRP, and is expected to be of interest to scientists, managers and planners involved in water resources assessment in urban areas. This publication contains seven individual reports, each of them was indexed separately

    International Nuclear Information System (INIS)

    2001-06-01

    The ever increasing human population and dwindling land and water resources worldwide make it essential to produce more food, fibre and fodder from less and less land. During the last century, plant breeding contributed remarkably to increasing food by producing varieties which give higher yield, have improved quality and nutrition, and resist diseases and pests. Nearly 50% of the increase in food production in Asia during the last fifty years can be attributed to the high yielding, short height varieties of rice and wheat, the remaining to the improved agronomic inputs and management. Many crops, such as cassava, potato, pineapple, sweet potato, sugarcane, banana and plantain are major food crops, and others such as sugarcane and pineapple are important to the economies of many developing countries. One of the solutions to have a sustainable and secure food production is to breed varieties which are tolerant of stress conditions during their growth and development. Hence a Co-ordinated Research Project on In vitro Techniques for Selection of Radiation Induced Mutations Adapted to Adverse Environmental Conditions was initiated and focused primarily on the improvement of vegetatively propagated plants. Since the inception of this project, several participating scientists established the optimal dose requirement for in vitro cultured material. Investigations were carried out on the effect of radiation to alter traits which affect survival under stress conditions and high temperature stress in potato, pineapple, sweet potato and garlic. The possibility to change traits such as tolerance to saline and water logged soils in sugarcane and gene regulation for salinity tolerance were studied. The limited number of available reports suggest that callus cultures are much more sensitive to radiation treatment and require much lower doses (2 to 5 Gy) than stem cuttings or seeds, and that relatively higher doses (15 to 20 Gy) cause necrosis or loss of regenerative capacity.

    The IAEA and FAO, through the activities of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture and their technical co-operation programmes, support the introduction of nuclear and related techniques to improve animal disease diagnosis and surveillance in developing countries. At a workshop hosted by the Australian Centre for International Agricultural Research (ACIAR) and the Department of Livestock Development (DLD) of Thailand, in Lampang, Thailand, in September 1993, an analysis of the results of an ACIAR project on foot-and-mouth disease (FMD) as well as national reports from twelve other Asian countries clearly demonstrated that the control and eradication of FMD in Asia is both a national and regional problem (vaccination alone costs in the region US $380 million annually). It was concluded that a co-ordinated regional approach was the only realistic way forward for controlling and eventually eradicating FMD from the region. It was agreed that the OIE would lead this co-ordinated regional programme in close co-operation with FAO, ACIAR, other relevant international organizations and national governments. Results of the ACIAR Project also clearly demonstrated the immense value of ELISA based systems for the diagnosis and control of FMD within Thailand. The meeting, therefore, recommended that an essential component of a regional strategy was to have, as a minimum, ELISA tests for the detection of FMD virus and for assessing the antibody status of livestock population in each country in the region. In support of this concept, the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture established a co-ordinated research project (CRP) with the primary aim of establishing and documenting appropriate mechanisms for introducing and using ELISA based technologies for FMD diagnosis and surveillance in participating countries.

    Radiation techniques are being used for synthesis of hydrogels, functional polymers, interpenetrating systems, chemical modification of surfaces, immobilization of bioactive materials, synthesis of functional micro- and nanospheres and processing of naturally derived biomaterials. Potential medical applications of these biomaterials include implants, topical dressings, treatment devices and drug delivery systems. Biotechnological applications include diagnostic assays, separation and purification systems, immobilized enzyme and cell bioprocesses and cell culture surfaces. The main objective of the CRP on The use of Radiation Processing to Prepare Biomaterials for Application in Medicine was to co-ordinate the research carried out in the participating countries, to ensure that different research programmes complement each other and the information exchange is available to all. Furthermore, the objective was to expand the use of ionizing radiation in two major areas: synthesis of polymers and gels for medical a...

  8. Application of personal computers to enhance operation and management of research reactors. Proceedings of a final research co-ordination meeting

    1998-02-01

    The on-line of personal computers (PCs) can be valuable to guide the research reactor operator in analysing both normal and abnormal situations. PCs can effectively be used for data acquisition and data processing, and providing information to the operator. Typical areas of on-line applications of PCs in nuclear research reactors include: Acquisition and display of data on process parameters; performance evaluation of major equipment and safety related components; fuel management; computation of reactor physics parameters; failed fuel detection and location; inventory of system fluids; training using computer aided simulation; operator advice. All these applications require the development of computer programmes and interface hardware. In recognizing this need, the IAEA initiated in 1990 a Co-ordinated Research Programme (CRP) on ''Application of Personal Computers to Enhance Operation and Management of Research Reactors''. The final meeting of the CRP was held from 30 October to 3 November 1995 in Dalata Viet Nam. This report was written by contributors from Bangladesh, Germany, India, the Republic of Korea, Pakistan, Philippines, Thailand and Viet Nam. The IAEA staff members responsible for the publication were K. Akhtar and V. Dimic of the Physics Section, Division of Physical and Chemical Sciences

    This publication covers the activities and accomplishments of eight countries that participated in a Co-ordinated Research Project (CRP) on Public Acceptance and Market Development of Irradiated Food in Asia and the Pacific, as presented at a final Research Coordination Meeting held in Bangkok, 20-25 September 1998. The CRP was implemented through research agreements with Bangladesh, China (one each for Shanghai and Beijing), the Republic of Korea, Malaysia, Pakistan, the Philippines, Sri Lanka, Thailand and Viet Nam, from 1994 to 1998. The technical work undertaken to bring food irradiation technology to the marketplace to address food security, public health and trade needs, is described. This covered the establishment of quality assurance procedures, the determination of irradiation doses for nontraditional as well as traditional foods, the conduct of techno-economic feasibility, and the identification of industry and consumer needs. In the majority of cases, R and D activities were undertaken in partnership with industry. Developments in the establishment and harmonization of regulations on food irradiation were also monitored. The participants made commendable progress in the marketing of irradiated food and in the understanding and promotion of consumer acceptance of the technology. This was demonstrated in the marketing of close to 179,000 tons of different food and related products through normal trading channels. While the volume of food irradiated varied with the capacity of irradiation plants in participating countries, the work showed that consumers would accept irradiated foods and that trade benefits would ensue from the application of the technology. Information dissemination was found to be a critical factor in public acceptance. The discussions at the final Research Co-ordination Meeting, which are also summarized in this publication, focused on key issues and recommendations to bring about the wider commercialization of food irradiation for the

  11. Radiation processing for safe, shelf-stable and ready-to-eat food. Proceedings of a final research co-ordination meeting

    2003-01-01

    The increasingly busy lifestyles of populations in many countries have driven the demand for safe, convenient and ready-to-eat food. Traditional food processes such as drying, canning or refrigeration offer a partial solution to this demand as the sensory quality of such food may be significantly affected or the products may be contaminated by pathogenic bacteria during preparation. For developing countries, safe shelf-stable food without the need for refrigeration would offer advantages. In addition, the increasing number of immuno-compromised populations in many countries requires a new approach to food safety to meet their needs. Irradiation offers a potential to enhance microbiological safety and quality of food through shelf-life extension. The benefits of irradiation as a sanitary treatment of many types of food are well known, some of which are applied commercially in several countries. Little data were available, however, on the effect of irradiation on minimally processed food and composite food including prepared meals. A Co-ordinated Research Project (CRP) on the Development of Safe, Shelf-Stable and Ready-to-Eat Food through Radiation Processing therefore was implemented by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture in 1996 to evaluate the role of irradiation for such food. The results were encouraging as irradiation offers promise as a sanitary treatment to ensure microbiological safety and shelf-life extension of several types of food products including pre-cut vegetables and some sous-vide meals, chilled ready-prepared meals, chilled ready-to-eat meat products, food for immuno-compromised patients/populations, sterile meals, ready-to-eat-food of intermediate moisture content.

    2001-04-01

    Vibrio spp. comprises an important group of pathogenic bacteria in food that often causes human illness and even death when the contaminated food is consumed raw or improperly cooked. The most dangerous member of this group, the El Tor strain of V. cholerae, was responsible for the cholera pandemic which started in Peru in 1991 and spread to nearby countries, resulting in hundreds of thousands of cases and thousands of deaths. Recognizing the role of irradiation to ensure the microbiological safety of food, the Pan American Health Organization of the World Health Organization and the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture jointly sponsored a Co-ordinated Research Project (CRP) on the Use of Irradiation as a Public Health Intervention Measure to Control Foodborne Diseases in Latin America and the Caribbean, to assess the efficacy of this technology for food protection. The CRP was initiated in 1993 and concluded in 1998. The results of this CRP demonstrated that irradiation is effective for ensuring the microbiological safety of food naturally contaminated by Vibrio spp. This process offers unique benefits for decontamination of seafood, often contaminated with this group of aquatic bacteria at the source, and fresh vegetables that may be contaminated during production and handling, especially when these products are consumed raw or not thoroughly cooked. Because of the sensitivity of this group of bacteria to radiation, the dose required to ensure microbiological safety of food against them is not more than 1 kGy. The CRP also generated data on the effectiveness of irradiation to control infection by pork tapeworm (Taenia solium metacestode). However, the results of these studies were not conclusive enough for publication. This publication presents the research results reported at the final Research Co-ordination meeting on this CRP held in Havana, Cuba, 16-20 November 1998

    The present report summarizes the final results of the IAEA Co-ordinated Research Programme on ''Activation Cross Section for the Generator of Long-lived Radionuclides of Importance in Fusion Reactor Technology''. The goal of the CRP was to obtain reliable information (experimental and evaluated) for 16 long-lived activation reactions of special importance to fusion reactor technology. By limiting the scope of the CRP to just 16 reactions it was possible to establish a very effective focus to the joint effort of many laboratories that has led to the generation of a set of valuable new data which provide satisfactory answers to several questions of technological concern to fusion.

    The primary purpose of this CRP was to provide a co-ordinated international effort to assemble and evaluate relevant data using sound technical judgement concerning the effects that fires, explosions or breaches of hulls of ships might have on the integrity of radioactive material packages. The probability and expected consequences of such events could thereby be assessed. If it were shown that the proportion of maritime accidents with severity in excess of the IAEA regulatory requirements was expected to be higher than that for land transport, then pertinent proposals could be submitted to the forthcoming Revision Panels to amend the IAEA Regulations for Safe Transport of Radioactive Material and their supporting documents. Four main areas of research were included in the CRP. These consisted of studying the probability of ship accidents; fire; collision; and radiological consequences

    Environmental pollution is a cause of ever increasing concern in the world. The UN Conference on Environment and Development (Rio, Brazil, 1992) reaffirmed the importance of protecting the environment within the context of sustainable development. Arising out of this conference, the Rio Agenda 21 declaration called for a number of nationally determined action programmes, with international assistance and co-ordination under 'Capacity 21', concerning environmental monitoring and assessment, including the use of biological markers. Biomonitoring is an appropriate tool for assessing the levels of air pollution. In several developed countries biomonitoring is used on a regular basis for such surveys. Application of biomonitors has several advantages compared to the use of direct measurements of contaminants, related primarily to the permanent and common occurrence in the field, the ease of sampling and trace element accumulation. Furthermore, biomonitors provide a measure of integrated exposure over an extended period of time, are present in remote areas and no expensive technical equipment is involved in collecting them. Suitably chosen biomonitors accumulate contaminants over certain periods of time, concentrate them, thus allowing more reliable analytical measurements. Simple and cheap sampling procedures (in contrast to direct measurements) allow a very large number of sites to be included in the same survey, permitting detailed geographical patterns to be drawn. In combination with the specimen banking (long-term storage) of selected samples, biomonitoring can be an effective tool for pollutant mapping and trend monitoring by real time and retrospective analysis. By application of appropriate statistical tools, information can also be obtained on the type and location of pollution sources as well as on the short, medium and long range trans-boundary transport of environmental pollutants.

    The fourth Research Co-ordination Meeting (RCM) of the Co-ordinated Research Project (CRP) on 'Updated Codes and Methods to Reduce the Calculational Uncertainties of the LMFR Reactivity Effect' was held during 19-23 May, 2003 in Obninsk, Russian Federation. The general objective of the CRP is to validate, verify and improve methodologies and computer codes used for the calculation of reactivity coefficients in fast reactors aiming at enhancing the utilization of plutonium and minor actinides. The first RCM took place in Vienna on 24 - 26 November 1999. The meeting was attended by 19 participants from 7 Member States and one from an international organization (France, Germany, India, Japan, Rep. of Korea, Russian Federation, the United Kingdom, and IAEA). The participants from two Member States (China and the U.S.A.) provided their results and presentation materials even though being absent at the meeting. The results for several relevant reactivity parameters obtained by the participants with their own state-of-the-art basic data and codes, were compared in terms of calculational uncertainty, and their effects on the ULOF transient behavior of the hybrid BN- 600 core were evaluated. Contributions of the participants in the benchmark analyses is shown. This report first addresses the benchmark definitions and specifications given for each Phase and briefly introduces the basic data, computer codes, and methodologies applied to the benchmark analyses by various participants. Then, the results obtained by the participants in terms of calculational uncertainty and their effect on the core transient behavior are intercompared.

    The Co-ordinated Research Programme (CRP) on the Application of DNA Based Marker Mutations for Improvement of Cereals and Other Sexually Reproduced Crop Plants represents the first of three CRPs dealing with the application of molecular markers to mutations and plant breeding and was implemented between 1992 and 1996. A second companion CRP entitled Use of Novel DNA Fingerprinting Techniques for the Detection and Characterization of Genetic Variation in Vegetatively Propagated Crops devoted to the application of molecular markers in vegetatively propagated crops species was implemented between 1993 and 1997. One positive consequence of these two CRPs has been the implementation of a third CRP entitled Radioactively Labeled DNA Probes for Crop Improvement, which began in 1995 and aims to provide enabling technologies, in the form of probes and primers, to laboratories in developing countries. The rapid development of molecular marker technologies has also resulted in a dramatic increase in request from developing Member States for technical co-operation projects utilizing molecular markers to improve local varieties for biotic and abiotic stresses and other traits of relevance. With the intensified use of induced mutations in genetic studies, it will be important to continue the important work of understanding induced mutations at the molecular level. Evidence of the progress made in implementing molecular marker technologies in laboratories around the world is presented in this publication, which contains the results presented by the participants at the fourth and final Research Co-ordination Meeting of the CRP held in Vienna, 4-8 November 1996. The FAO and IAEA wish to express their sincere appreciation to the participants of the meeting for their work during the project period resulting in the summary and scientific reports presented in this publication.

    1999-12-01

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

    2002-12-01

    Electron paramagnetic resonance (EPR) dosimetry is a physical method for the assessment of absorbed dose from ionising radiation. It is based on the measurement of stable radiation induced radicals in human calcified tissues (primarily in tooth enamel). EPR dosimetry with teeth is now firmly established in retrospective dosimetry. It is a powerful method for providing information on exposure to ionising radiation many years after the event, since the 'signal' is 'stored' in the tooth or the bone. This technique is of particular relevance to relatively low dose exposures or when the results of conventional dosimetry are not available (e.g. in accidental circumstances). The use of EPR dosimetry, as an essential tool for retrospective assessment of radiation exposure is an important part of radioepidemiological studies and also provides data to select appropriate countermeasures based on retrospective evaluation of individual doses. Despite well established regulations and protocols for maintaining radiation protection dose limits, the assurance that these limits will not be exceeded cannot be guaranteed, thus providing new challenges for development of accurate methods of individual dose assessment. To meet some of these challenges, in 1998 the IAEA initiated a co-ordinated research project (CRP) with the objective to review the available methods, current research and development in EPR biodosimetry technology, which may be of practical use. The major goal of this CRP was to investigate the use of EPR biodosimetry for reconstruction of absorbed dose in tooth enamel with the aim of providing Member States with up-to-date, and generally agreed upon advice regarding the most suitable procedures and the best focus for their research. The co-ordinated research project was conducted over four years and this publication presents the results and findings by a group of investigators from different countries.

To define the magnitude of the obesity/NIDDM problem in developing countries. 2. To identify vulnerable groups at high risk. 3. To describe the metabolic mechanisms involved. The purpose of this first Research Co-ordination Meeting (RCM) was thus to develop a worldwide collaboration in the use of nuclear and isotopic techniques to investigate the aetiology of degenerative diseases in ageing. All countries participating in this CRP are going through the epidemiological transition with changes in lifestyles to approach those seen in the developed nations

    A Co-ordinated Research Programme (CRP) on 'Development of Kits for Immunoradiometric Assays for tumour markers' was started towards the end of 1997. Ten laboratories from different parts of the world with experience in development of immunoassays are participating in this project and the first Research Co-ordination Meeting (RCM) was held at the Agency Head Quarters in Vienna during 3-7 December, 1997. Based on the discussions and recommendations made during this meeting, the participants have carried out the project work at their laboratories during the past 18 months. During this period two consignments (November 98 and March 99) of some of the essential reagents, namely the capture Mab (Mab 66; 5 mg), tracer Mabs (Mab 10; 0.5 mg for total PSA and Mab 30; 0.5 mg for free PSA assay) and PSA antigen (1.3 mg, 80% pure) were shipped to each participant to enable them to develop the assays and to assess their own in-house reagents. The second RCM was held at the University of Alberta, Edmonton, Canada, to review the results obtained thus far and to discuss the actions to be taken in the next phase of the project. All the participants presented the work done at their respective laboratories and discussed the results obtained. On the whole, it was observed that significant progress has been achieved by all the participants. In the area of production of monoclonal antibodies, significant accomplishment was achieved by Cuba, China and India. All the three laboratories had produced monoclonal antibodies against PSA and had been successful to various extents. Cuba could identify specific antibodies that could be used as capture antibody as well as tracer antibodies for free and total PSA assays. Small aliquots of these were brought and distributed to the participants for individual evaluation. China has also identified the monoclonals for an IRMA for total PSA while India had identified a monoclonal that could be used for coating. The selected antibodies have compared very

    2000-06-01

    In many Member States the use of large cobalt-60 gamma ray facilities and electron beam accelerators with beam energies from about 0.1 to 10 MeV for industrial processing continues to increase. For these processes, quality assurance relies on the application of well established dosimetry systems and procedures. This is especially the case for health regulated processes, such as the radiation sterilization of health care products, and the irradiation of food to eliminate pathogenic organisms or to control insect pests. A co-ordinated research project (CRP) was initiated by the IAEA in June 1995. Research contracts and research agreements in areas of high dose dosimetry were initiated to meet these challenges. The major goals of this CRP were to investigate the parameters that influence the response of dosimeters and to develop reference and transfer dosimetry techniques, especially for electron beams of energy less than 4 MeV and for high energy X ray sources (up to 5 MV). These will help to unify the radiation measurements performed by different radiation processing facilities and other high dose dosimetry users in Member States and encourage efforts to obtain traceability to primary and secondary standards laboratories. It will also aim to strengthen and expand the present International Dose Assurance Service (IDAS) provided by the IAEA

    The Co-ordinated Research and Environmental Surveillance Programme relevant to sea disposal of radioactive waste (CRESP) was created in 1981 in the framework of the 1977 Decision of the OECD Council establishing a Multilateral Consultation and Surveillance Mechanism for Sea Dumping of Radioactive Waste. The main task of CRESP was to set up a site-specific scientific research programme to increase current knowledge of the processes controlling the transfer of radionuclides in the marine environment, so that impact of past dumping could be monitored and future assessments could be based on more accurate and comprehensive scientific data. The CRESP mandate was extended in 1987 to respond to a request from the Paris Commission to include consideration of radioactive discharges in the maritime area covered by the Convention on the Prevention of Marine Pollution from Land-Based Sources. This report summarizes the CRESP activities carried out during the 1986-1990 five year phase. Concerning the review of deep sea results, the report relates progress achieved above the level of knowledge which was available when the present phase of the CRESP programme was decided and which has been taken into account in the 1985 Site Suitability Review. With respect to coastal discharges, it presents a summary of R and D work undertaken by member countries, including those carried out in other programmes such as MARINA. Finally, it makes proposals for future work within CRESP

    The use of isotopes has revolutionized the field of human nutrition research, but has been of greatest benefit to industrialized countries. The International Atomic Energy Agency is sponsoring programmes using isotopic and related technologies in human nutrition research to address issues that are of priority to developing countries. Scientists participating in the Coordinated Research Programme (CRP) on ''Amino Acid and Protein Metabolism in Malnourished Populations of Developing Countries'' are conducting research on the interaction between infection and amino acid metabolism, particularly the potential diversion of substrates from anabolic pathways to fight infection in marginally nourished children during periods of infections. This topic is of great importance to the nutritional status of children in developing countries, who frequently or chronically have infections and who, as a consequence, may have alterations in nutrient requirements. The CRP has developed and implemented a standardized protocol for measuring leucine oxidation during infection in 8 different countries. The CRP is expected to contribute important new knowledge about interactions between protein utilization, the stresses of unhygienic environments, and infections in marginally nourished people. This information is expected to be applicable to efforts to increase efficient utilization of limited food resources in developing countries. Another highlight of the CRP is that it represents an international team of nutrition scientists who together are building nutritional biology research capabilities in developing countries.

  18. Standardization of medfly trapping for use in sterile insect technique programmes. Final report of a co-ordinated research programme 1986-1992

    International Nuclear Information System (INIS)

    1996-05-01

    As different trapping systems are often applied in different countries or regions, it becomes difficult to compare population data from these regions. Also, population measurements taken with the same trap but in different climates are again difficult to compare. Given the cosmopolitan nature of the medfly and the area-wide control programmes developed against it, it is necessary to be able to estimate or compare fly population levels even when measured with different traps and in different environments. In view of the above, the Joint FAO/IAEA Division, which has long been involved in medfly eradication and/or control activities in different regions, organized a co-ordinated research programme with the objective to compare and to standardize several of the most common medfly traps under different weather, host-tree and population density conditions. Tests were carried out in eight different countries and climates in northern Africa, southern Europe and Central America. Production of fruits preferred by the medfly is important in all eight countries. Refs, figs, tabs

    The Co-ordinated research programme on the benchmark study for the seismic analysis and testing of WWER-type nuclear power plants was initiated subsequent to the request from representatives of Member States. The conclusions adopted at the Technical Committee Meeting on Seismic Issues related to existing nuclear power plants held in Tokyo in 1991 called for the harmonization of methods and criteria used in Member States in issues related to seismic safety. The Consulltants' Meeting which followed resulted in producing a working document for CRP. It was decided that a benchmark study is the most effective way to achieve the principal objective. Two types of WWER reactors (WWER-440/213 and WWER-1000) were selected as prototypes for the benchmark exercise to be tested on a full scale using explosions and/or vibration generators. The two prototypes are Kozloduy Units 5/6 for WWER-1000 and Paks for WWER-440/213 nuclear power plants. This volume of Working material contains reports on the effects of Armenia earthquakes on selected power, industry and commercial facilities and seismic functional qualification of active mechanical and electrical components tested on shaking table

    The International Atomic Agency (IAEA) has initiated a new Co-ordinated Research Programme (CRP) on Hydrogen and hydride induced degradation of the mechanical and physical properties of Zirconium-based alloys. In the first phase of this CRP the methodology for measuring the velocity of Delayed Hydride Cracking (DHC) should be established and participating laboratories from about nine countries around the world carry out identical tests in 'round robin'. The objective of the present work is to establish at Studsvik laboratory the method of a constant load cracking test on unirradiated Zr-2.5Nb and attain a comparison of results between laboratories. Constant load tests are performed on specimens cut from unirradiated CANDU Zr-2.5Nb pressure tube and the rate of crack propagation is determined in each test. Pre-hydrided specimens for testing are supplied from the host laboratory. Six specimens have been tested for delayed hydride cracking (DHC) at 250 deg C. The axial crack growth velocities measured in the tests are within the interval of 8.62x10{sup -8} - 1.06x10{sup -7} m/s. The results obtained agree well with the earlier published data for similar materials and test conditions.

    The IAEA organized a co-ordinated research programme (CRP) in 1991 for studying the properties of a few most promising magnetizable immunoadsorbents and standardizing some important radioimmunoassay and immunoradiometric assay procedures using them with the ultimate aim of expanding the application of these assays in developing countries using indigenously prepared reagents. Ten laboratories from nine countries of Asia, Latin America and Europe participated in this CRP which was concluded in 1995. Three different magnetizable particles prepared and investigated by the participants, namely magnetite, magnetite coated with silane and magnetite coated with polyacrolein, have emerged suitable for use in radioimmunometric assays from this CRP. Methods have been developed for coupling antibodies to these particles and using the resultant immunoadsorbents for assaying several important hormones and proteins including T 3 , T 4 , fT 3 , fT 4 , reverse T 3 , TSH, thyroglobuling(Tg), Tg-antibodies, HCG, LH, cortisol, FSH and prolacting. All the participating laboratories could develop in house methodology for solid phase assays based on magnetizable particles during the course of the CRP and benefit from the exchange of materials, information and experience amongst them. This report includes detailed results obtained by the participating laboratories as well as a summary and assessment of the achievements of the CRP. It also includes suggestions for areas of investigation for pursuing in the future. Refs, figs, tabs

    The prepared convenience foods sector has become a significant part of the economy of many developed countries with a similar trend evolving in developing countries, where many types of ethnic foods are now also prepared as convenience foods. For example, the prepared convenience foods sector in Ireland is a significant part of the Irish economy. In 2001, just under half of the sector's total output was exported for a value of 841 million Euro, representing a 12% annual increase. The sector's strong growth both in exports and in total sales has made it one of the fastest growing sectors of the food industry in many countries. Consumer studies carried out on convenience foods have shown that perceived time pressures contribute positively to the purchase of both prepared meals and take-away meals. Other reasons found to contribute positively to the purchase of prepared meals include not enjoying cooking for oneself, a value-for-money perception of convenience foods and different eating times of family members. As a consequence of the increased market for convenience foods particularly, the food industry is interested in developing ways for the production of prepared meals, which are safe to eat, have an acceptable shelf-life and are of good sensorial and nutritional quality. One technology with the potential to achieve these objectives is food irradiation, which is one of the most thoroughly researched food processing technologies ever developed. It is thought that research into the application of ionizing radiation to products such as prepared meals could be of unique benefit to the food industry, particularly in developing countries where the microbiological safety of many ethnic dishes is questionable and their shelf-life limited due to the conditions under which they are produced and stored. Food irradiation used on its own or in combination with other processes such as chilling could significantly enhance the microbial safety of such products as well as

    The first Research Co-ordination Meeting (RCM) of the Co-ordinated Research Project (CRP) on 'the development of strategies for the effective monitoring of veterinary drug residues in livestock and livestock products in developing countries' was held in the Vienna International Centre from 2 to 6 September 2002. Twelve Research Contracts (RCs) and 3 Research Agreements (RAs) have been awarded under this CRP and all awardees, the Project Officer and a guest speaker from the Austrian Agency for Health and Food Safety (AAHFS) participated in the RCM. The objective of the RCM was to plan the first phase of the CRP, initiation of the development and validation of methods. Specific objectives were to: Agree upon a small number of veterinary drugs upon which to focus the research; Agree upon analytical methodologies to be employed; formulate individual work plans for each research contract holder within the framework of the overall work plan. Each RC holder presented an overview of residues monitoring from the perspective of their respective countries. Emphasis was placed on problems encountered and future requirements. The participants visited the Austrian National Reference Laboratory for veterinary drug residues at Moedling and discussed the activities there with Mr. Kuhn and laboratory staff. An overall framework for phase of the CRP, focusing upon the compounds and analytical techniques of major importance to the majority of participants, was formulated. Each RC holder discussed and revised their individual work plan with the RA holders and the PO. The overall framework was then reviewed and a summary of the individual work plans presented. Conclusions and recommendations were drafted

    In the last few years, the World Health Organisation (WHO) has organised the development of new reference data for infant growth, reflecting the fact that previous growth reference data were based in part on formula-fed infants. With the benefits of breast-feeding for infant health increasingly recognised, and the differences in growth rate between breast-fed and formula-fed infants replicated in many populations, growth reference data from breast-fed infants became a priority. The importance of early growth for adult health is also increasingly appreciated, with numerous studies linking early nutrition and growth patterns to the risk of cardiovascular disease, obesity, type 2 diabetes and stroke in later life. To support these new reference data, it is also important to assess the breast-milk and nutrient intakes of normally-growing breast-fed infants, in order to revise recommendations for their energy requirements. This coordinated research project (CRP) was therefore initiated by the International Atomic Energy Agency to investigate milk intake and growth in several populations from developing countries. A secondary aim was to continue the technological development of methodologies that allow the required measurements to be undertaken in free-living mother-infant pairs in field conditions. The measurement of breast-milk intake was until recently undertaken using test-weighing, whereby the infant is weighed before and after each feed during one or more 24 hour periods. This method is intrusive, cumbersome, and unsuitable for many populations under field conditions. The development of the dose-to-the-mother deuterium oxide turnover method, by which maternal breast-milk transfer can be assessed by isotopic kinetics, has transformed the ability to measure milk intake in wholly or partially breast-fed infants in developing countries. The current CRP aimed to apply this technology to a variety of populations, ensuring that the data were comparable between countries

    The result of a CRP completed in 1989 and entitled ''Regional Network for Improving the Reproductive Management of Milk, Meat and Fibre Producing Livestock with the Use of Radioimmunoassay Techniques'' clearly indicated that nutritional inadequacies and livestock management deficiencies were the major factors affecting livestock productivity in Latin America. Based on these conclusions a CRP entitled ''Development of Feed Supplementation Strategies for Improving Ruminant Productivity on Small-holder Farms in Latin America through the Use of Immunoassay Techniques'' was initiated late in the same year. The primary aim of the Programme was to improve the productivity of indigenous ruminant livestock species maintained on typical small-holder farms in the region. Central to the approach was to first identify the nutritional and management constraints which affect reproductive and productive efficiency, and subsequently to devise and test corrective measures which would be practical, sustainable and economically viable. Important related goals of the Programme were to enhance the level of expertise and the educational quality within animal production research institutes in the region, to encourage close contact between scientists and institutions in developing and developed countries and to promote scientific information exchange on a regional basis.

  17. Reference materials for microanalytical nuclear techniques. Final report of a co-ordinated research project 1994-1999

    International Nuclear Information System (INIS)

    2002-06-01

    A significant problem in the use of solid- and small-sample techniques is a general lack in suitable certified reference materials (CRM). Essentially, no CRM are certified for the small sample sizes typically used. Direct utilization of most existing CRM in solid sampling analysis procedures, typically 1 mg sample size, is often difficult or even impossible because trace components may not be sufficiently homogeneously distributed in the sample or their homogeneous distribution has not been tested. To explore the production, characterization and use of CRM for determinations with sample sizes much smaller than currently used, the Coordinated Research Program focused on selection of biological and environmental materials suitable for microanalytical techniques, definition of specifications for suitable CRM, evaluation of existing CRM for use with microanalytical techniques, evaluation of requirements for sample pre-treatment, evaluation of analytical techniques and research on development of techniques to be used in characterizing the homogeneity and chemical composition of small samples, and application of analytical techniques to the characterization of candidate reference materials for use with microanalytical techniques

    2004-11-01

    Results were discussed that have been obtained during two and a half years of work under the Coordinated Research Project (CRP) on Improvement of the Standard Cross Sections. Major attention was focused on reducing the ambiguity between different R-matrix fits; seeking consensus between participants about what approach should be used to minimize the effect of Peelle's Pertinent Puzzle; procedures for combining the results of the R-matrix model with non-model fits; and determining the reactions and energies where smoothing should be used. The proposed timetable includes the release of the standard cross section tables by 18 November 2004 and preparing a draft report with a detailed description of the evaluation procedure by 30 April 2005.

    2003-01-01

    Results obtained during the first six months of the Coordinated Research Project (CRP) on Improvement of the Standard Cross Sections for Light Elements were presented. Attention focused on studies of the reduction in uncertainty for the model and non-model least squares fits, intercomparison and testing of different computer codes based on the nuclear model, non-model general least square and Bayesian approaches to the evaluation of standard reaction cross sections and covariance matrix of their uncertainties. The reasons leading to the underestimation of uncertainties and bias in the evaluated values were discussed and solutions to these problems were outlined. A coordinated working plan was prepared which will result in the preparation of new reaction cross section standards for light and heavy elements by 2004. (author)

  20. Treatment of liquid effluent from uranium mines and mills. Report of a co-ordinated research project 1996-2000

    International Nuclear Information System (INIS)

    2004-10-01

    Treatment and control of liquid effluents produced during uranium mining and milling operations is an integral part of environmental project management. Research has continued to add to the large body of science that has been built up around the treatment of radioactive and non-radioactive effluents to minimize their long-term environmental impact. The objective of the meetings on which this publication is based was to exchange information on active effluent treatment technologies that have application during operations and passive treatment techniques such as constructed wetlands and use of micro-organisms that are applicable during project reclamation and long-term care and maintenance. Papers describe effluent treatment case histories from active uranium mining and processing operations as well as effluent treatment research on both active and passive systems that have potential application under a wide range of operating and post-operational conditions including new information on high-density sludge from effluent neutralization (Australia), aerated manganese hydroxide for removal of radium (China), nanofiltration and macropore resins to treat mine water (Australia and China), in situ microbial treatment and permeable reactive walls for treatment of contaminated groundwater (Germany), construction of wetlands to treat mine water runoff (Australia and Germany), biogenic granules to remove 226 Ra from mill effluent (India), self-remediation of acidic in situ leach aquifers (Kazakhstan) and sorption characteristics of soil for self-remediation of contaminated groundwater (Hungary). These and other topics presented in this publication will be of interest to technical personnel who deal with day-to-day practical aspects of liquid effluent control and treatment at uranium production facilities worldwide

  1. Application of non-destructive testing and in-service inspection to research reactors. Results of a co-ordinated research project

    2001-12-01

    -destructive testing (NDT), are generally called in-service inspections (ISI) and, together with the above specific techniques, are the subject of the present TECDOC. The main objectives of the TECDOC are to present a number of these special techniques and to give guidance for their application. The guidance and recommendations given in this publication form the basis for the conduct of ISI of research reactors with limited hazard potential to the public. This TECDOC is based on the results of a Co-ordinated Research Project (CRP) on the Application of Non-destructive Testing and In-service Inspection to Research Reactors that the IAEA organized in 1995 to supplement its activities on research reactor ageing within its Research Reactor Safety Programme (RRSP). Because of the importance of such in-service inspections within the programmes for the management of ageing in research reactors, this TECDOC will be useful to a large fraction of the currently operating research reactors that are over 30 years old

    2004-03-01

    Results are presented following one and a half years of work under the Coordinated Research Project (CRP) on Improvement of the Standard Cross Sections for Light Elements. They include the use of the refined resonating group model for the theoretical prediction of the R-matrix poles and preliminary R-matrix model fits of the full experimental database for the 6 Li+n system obtained with different codes. Significant attention was paid to the exclusion of the bias in the evaluated data caused by the possible presence of Peelle's Pertinent Puzzle effect in the experimental data. Updates were also presented of the experimental database for light and heavy element standards including fission cross sections up to 200 MeV. First results and observed trends for all standard reactions are given, including the preliminary results of combining the model (for light elements) and non-model fits. The timetable for further work was agreed, which should lead to new reaction cross section standards for light and heavy elements by the end 2004. (author)

    Regarding to PSA CIGB- IAEA project the center will be generating a panel of monoclonal antibodies against prostatic specific antigen (PSA) free and complexed to α1 antichymotrysin, and tissue polypeptide specific (TPS) antigen as potentially useful markers for the diagnosis of prostate and breast cancer using IRMA or RIA. The panel of monoclonal antibodies would be distributed in Cuba and another countries for the development of diagnostic Kits. The detailed objectives of the contract are: 1. To obtain a panel of monoclonal antibodies against prostatic specific antigen (PSA) complexed antichymotrysin. 2. To obtain a panel of monoclonal antibodies against free PSA. 3. To study the potential use for detect free or complexed PSA in the serum of patients with benign prostatic hypertrophy or prostatic neoplasia. 4. To obtain a panel of monoclonal antibodies against TPS. 5. To develop and validate IRMA or RIA assays using the panel of monoclonal antibodies. The objectives are designed according to the present knowledge on the field of monoclonal antibodies and diagnostic kits. Basic techniques for developing monoclonal antibodies (Mabs) have been used in our division for more than 10 years. The possibility to acquire commercial PSA antigen could reduced the overall time to obtain the Mabs, according with our experience. All these aspects support the idea that the proposing Cuban institutes are able to develop this research project and that its benefits will be applicable in the country and in the region

    2002-06-01

    This CRP was recommended by the Consultants meeting on Ion Beam Techniques Applied to Semiconductor and Related Advanced Materials, held in April 1997 in Vienna. The consultants proposed to have a CRP in the field of application of MeV ion beams for the development and characterization of semiconductor materials. The CRP was approved and a first RCM was held in Vienna between 2-5 June 1998, in order to stimulate ideas and to promote collaborations among CRP participants. The goals and practical outcomes of the CRP were defined and several specific topics were identified including: optoelectronic characterization of semiconductor materials and devices by ion microbeams, characterization of thin films, defect transformations in semiconductors, light element analysis. One important recommendation was that sample exchanges among different laboratories be strongly encouraged. The participants presented individual activities on their projects, all subjects of research were identified and linked with approved individual projects. Collaboration among the participants was discussed and established. Some modifications to work plans were adopted. As proposed during the first RCM, the final RCM was held at the Ruder Boskovic Institute, Zagreb, Croatia, between 25 and 29 September 2000, with the purpose of reviewing/discussing the results achieved during the course of the CRP and to prepare a draft of the final report and associated publication. This document contains summary of the CRP and ten individual reports presented by participants. Each of the reports has been indexed separately

    2002-01-01

    One of the tasks of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture is to promote the use of nuclear techniques for improving disease diagnosis and monitoring disease control programmes in order to optimise animal production in developing countries. An applied research programme was initiated in 1998 with funding from the Regular Budget to promote farmyard poultry production in Africa by developing practical vaccination strategies against Newcastle disease and Gumboro disease in various countries in Africa and monitoring immunity using an ELISA technique. Following initial discussions with experts from various universities and FAO it became clear that in order to improve farmyard poultry production effectively it was essential to initiate a holistic approach. Consequently, it was decided to first collect production data of the existing situation in a standardised fashion, subsequently analyse the production constraints and finally initiate interventions not only by vaccinating poultry but also by introducing improvements in housing, feeding and commercialisation. At the same time a practical and robust ELISA test for detecting antibodies against Newcastle disease was developed at the FAO/IAEA Agriculture and Biotechnology Laboratory in Seibersdorf, Austria. The results of the standardised survey to collect production data of the current situation are reported in the present publication together with an analysis of production constraints, a number of review articles on family poultry production in Africa and a comparative analysis of the results from the various countries

  6. Evaluating agronomic effectiveness of phosphate rocks using nuclear and related techniques: Results from an FAO/IAEA co-ordinated research project

    Zapata, F.

    2000-01-01

    An FAO/IAEA Co-ordinated Research Project, 'The use of nuclear and related techniques for evaluating the agronomic effectiveness of phosphatic fertilisers, in particular rock phosphates', was in operation during the period 1993-98. The research network comprised twenty-three scientists, of whom seventeen were in developing countries, with six in industrialized nations. Conventional and 32 P-isotope techniques were utilized to assess the bioavailability of P in soils amended with phosphate rock (PR) and water-soluble fertilisers, and to evaluate the agronomic effectiveness of PR products. No single chemical extraction method was found to be suitable for all soils and fertilisers. The Pi strip method showed promising results, but more testing is needed with tropical acid soils. The 32 P-phosphate-exchange kinetics method allowed a complete characterization of P dynamics, and provided basic information for estimating the kinetic pools of soil P. The agronomic effectiveness (AE) of PRs depends on their solubility (reactivity), which is related to the degree of carbonate substitution for phosphate in the apatite structure. Rock phosphates of low reactivity were unsuitable for direct application to annual crops. Research in Venezuela, China, Cuba, Brazil, and Thailand demonstrated that AE can be increased by partial acidulation, or by mixing with organic materials or a water-soluble source. The AE can be enhanced also through inoculation with mycorrhizal fungi and rhizobacteria. The AE, which depends on species, is particularly high in crops such as canola and lupin that exude organic acids from the roots. Agronomic effectiveness of PR is higher on soils with low pH, low available P, low exchangeable Ca, high cation exchange capacity and high organic-matter content. The 32 P-techniques are powerful tools for studying the factors that affect AE. Information from field trials was used to create a database for validating a model for providing recommendations for PR

  9. Verification of analysis methods for predicting the behaviour of seismically isolated nuclear structures. Final report of a co-ordinated research project 1996-1999

    International Nuclear Information System (INIS)

    2002-06-01

    This report is a summary of the work performed under a co-ordinated research project (CRP) entitled Verification of Analysis Methods for Predicting the Behaviour of Seismically isolated Nuclear Structures. The project was organized by the IAEA on the recommendation of the IAEA's Technical Working Group on Fast Reactors (TWGFR) and carried out from 1996 to 1999. One of the primary requirements for nuclear power plants and facilities is to ensure safety and the absence of damage under strong external dynamic loading from, for example, earthquakes. The designs of liquid metal cooled fast reactors (LMFRs) include systems which operate at low pressure and include components which are thin-walled and flexible. These systems and components could be considerably affected by earthquakes in seismic zones. Therefore, the IAEA through its advanced reactor technology development programme supports the activities of Member States to apply seismic isolation technology to LMFRs. The application of this technology to LMFRs and other nuclear plants and related facilities would offer the advantage that standard designs may be safely used in areas with a seismic risk. The technology may also provide a means of seismically upgrading nuclear facilities. Design analyses applied to such critical structures need to be firmly established, and the CRP provided a valuable tool in assessing their reliability. Ten organizations from India, Italy, Japan, the Republic of Korea, the Russian Federation, the United Kingdom, the United States of America and the European Commission co-operated in this CRP. This report documents the CRP activities, provides the main results and recommendations and includes the work carried out by the research groups at the participating institutes within the CRP on verification of their analysis methods for predicting the behaviour of seismically isolated nuclear structures

    1982-07-01

    Recent work on quantization in rotating co-ordinates showed that no radiation would be seen by an observer rotating with a constant angular speed. This work used a Galilean-type co-ordinate transformation. We show that the same result holds for a Lorentz-type co-ordinate system, in spite of the fact that the metric has a co-ordinate singularity at rΩ = 1. Further, we are able to define positive and negative energy modes for a particular case of a non-static, non-stationary metric. (author)

  11. Use of novel DNA fingerprinting techniques for the detection and characterization of genetic variation in vegetatively propagated crops. Proceedings of a final research co-ordination meeting

    International Nuclear Information System (INIS)

    1998-10-01

    Vegetative propagated crops, such as banana and platain, sweet potato, yam, sugarcane and cassava, represent important sources of food in the developing countries. Although some of these crops may produce seeds, they must for practical purposes be propagated vegetatively. As normal plant breeding strategies based on genetic hybridization are of limited value or not applicable to such crops, it is necessary to assess the genetic diversity already existing in these crops and to design breeding strategies accordingly. If the existing genetic variation is shown to be too narrow for breeding purposes, one promising possibility for the introduction of genetic variability is the use of mutations induced by radiation or chemical mutagens. This CRP focused on: the detection of genetic diversity induced by mutagenic treatment or in vitro culture; the development of crop-specific markers; and increasing co-operation between molecular biologists in advanced laboratories and plant breeders and molecular biologists in the developing countries. The success of this CRP is evidenced by the introduction and application of new molecular methods by laboratories in developing countries, specially for the analysis of local crop genetic diversity. These exciting preliminary results show the potential for applications in crop improvement but much work remains to be done. Many of the vegetatively propagated species are ''orphan crops'', under-investigated on the international level. The development of new uses of transgenesis for the development of edible vaccines should not be overlooked. The challenge that remains is in the application of these new tools for practical end-user oriented improvements in vegetatively propagated crops. The present publication summarizes the third and final Research Co-ordination Meeting on the Use of Novel DNA Fingerprinting Techniques for the Detection and Characterization of Genetic Variation in Vegetatively Propagated Crops

    Andreo, P.

    1999-01-01

    In 1987, the IAEA published a report entitled 'Absorbed Dose Determination in Photon and Electron Beams: An International Code of Practice' (IAEA Technical Reports Series No. 277) to advise users how to obtain the absorbed dose in water from the measurements made with an ionization chamber, calibrated in terms of air kerma. For high-energy photons (energies above 1 MeV) the chamber calibration was at a single photon quality (Cobalt-60 gamma rays). The scientific scope of the Co-ordinated Research Project is to investigate the accuracy of the new data and procedures included in the Code of Practice IAEA TRS-381. Differences with existing recommendations, published by national organizations, are to be evaluated to analyze the possible impact on patient dosimetry. The second Research Co-ordination Meeting (RCM) was organized to revise the activities in the Co-ordinated Research Project (CRP) and the status of the various projects. The status of the on-going work under the frame of the CRP was presented by the participants in the RCM during the first two days and each contribution discussed in detail. During the following days, plans were made on the work left for each participant to complete the project and the feasibility of preparing a report describing in detail the work done in the project

  15. Further analysis of extended storage of spent fuel. Final report of a co-ordinated research programme on the behaviour of spent fuel assemblies during extended storage (BEFAST-III) 1991-1996

    International Nuclear Information System (INIS)

    1997-05-01

    Considerable quantities of spent fuel continue to be produced and to accumulate in a number of countries. Although some new reprocessing facilities have been constructed, many countries are investigating the option of extended spent fuel storage prior to reprocessing or fuel disposal. Wet storage continues to predominate as an established technology. However, dry storage is becoming increasingly used with many countries considering dry storage for the longer term. This Technical Document is the final report of the IAEA Co-ordinated Research Programme on the Behaviour of Spent Fuel Assemblies During Extended Storage (BEFAST-III, 1991-1996). It contains analyses of wet and dry spent fuel storage technologies obtained from 16 organizations representing 13 countries (Canada, Finland, France, Germany, Hungary, the Republic of Korea, Japan, the Russian Federation, Slovakia, Spain, Sweden, the United Kingdom and the USA) which participated in the co-ordinated research programme as participants or observers. The report contains information presented during the three Research Co-ordination meetings and also data which were submitted by the participants in response to request by the Scientific Secretary. 48 refs, 4 tabs

  16. Long term behaviour of low and intermediate level waste packages under repository conditions. Results of a co-ordinated research project 1997-2002

    International Nuclear Information System (INIS)

    2004-06-01

    The development and application of approaches and technologies that provide long term safety is an essential issue in the disposal of radioactive waste. For low and intermediate level radioactive waste, engineered barriers play an important role in the overall safety and performance of near surface repositories. Thus, developing a strong technical basis for understanding the behaviour and performance of engineered barriers is an important consideration in the development and establishment of near surface repositories for radioactive waste. In 1993, a Co-ordinated Research Project (CRP) on Performance of Engineered Barrier Materials in Near Surface Disposal Facilities for Radioactive Waste was initiated by the IAEA with the twin goals of addressing some of the gaps in the database on radionuclide isolation and long term performance of a wide variety of materials and components that constitute the engineered barriers system (IAEA-TECDOC-1255 (2001)). However, during the course of the CRP, it was realized that that the scope of the CRP did not include studies of the behaviour of waste packages over time. Given that a waste package represents an important component of the overall near surface disposal system and the fact that many Member States have active R and D programmes related to waste package testing and evaluation, a new CRP was launched, in 1997, on Long Term Behaviour of Low and Intermediate Level Waste Packages Under Repository Conditions. The CRP was intended to promote research activities on the subject area in Member States, share information on the topic among the participating countries, and contribute to advancing technologies for near surface disposal of radioactive waste. Thus, this CRP complements the afore mentioned CRP on studies of engineered barriers.

    Doko, Bruno

    2000-01-01

    The present Co-ordinated Research Programme is to complement the FAO/IAEA Training and Reference Centre (TRC) for Food and Pesticide Control under the Centre's mission ''to assist Member States and their institutions to fulfill requirements to support the implementation of international safeguards/agreements relevant to food safety and control, the safe use of pesticides and sanitary and phytosanitary measures, by providing training, quality assurance services and technology transfer''. Based on the Global Environment Monitoring System - Food Contamination Monitoring and Assessment Programme (GEMS/Food) data and other national data on mycotoxin contamination, mycotoxins are a widespread problem of the food supplies in most countries. As a result, many countries have enacted regulations to control the level of mycotoxins in the national food supply as well as in food moving in international trade. At the international level, the Codex Alimentarius Commission, through its Committee on Food Additives and Contaminants and relevant commodity committees is considering the establishment of international guideline levels for various mycotoxins based on risk assessments performed by the Joint FAO/WHO Expert Committee on Food Additives. Codex activities are of particular importance in view of the World Trade Organization (WTO) Sanitary and Phytosanitary Measures (SPS) Agreement specifically refers to Codex standards, guidelines and recommendations as representing the international consensus on health and safety requirements for food based on sound scientific risk assessment. This will require national authorities to give greater attention to the development of consistent and standardised approaches to regulations and their enforcement, including sampling and methods of analysis. Consequently, it is essential that the analytical capabilities of laboratories in developing countries are strengthened in order to enable them to effectively monitor the mycotoxin content of food in

    The `renaissance` of the therapeutic applications of radiopharmaceuticals during the last few years was in part due to a greater availability of radionuclides with appropriate nuclear decay properties, as well as to the development of carrier molecules with improved characteristics. Although radionuclides such as {sup 32}P, {sup 89}Sr and {sup 131}I, were used from the early days of nuclear medicine in the late 1930s and early 1940s, the inclusion of other particle emitting radionuclides into the nuclear medicine armamentarium was rather late. Only in the early 1980s did the specialized scientific literature start to show the potential for using other beta emitting nuclear reactor produced radionuclides such as {sup 153}Sm, {sup 166} Ho, {sup 165}Dy and {sup 186-188}Re. Bone seeking agents radiolabelled with the above mentioned beta emitting radionuclides demonstrated clear clinical potential in relieving intense bone pain resulting from metastases of the breast, prostate and lung of cancer patients. Therefore, upon the recommendation of a consultants meeting held in Vienna in 1993, the Co-ordinated Research Project (CRP) on Optimization of the Production and quality control of Radiotherapeutic Radionuclides and Radiopharmaceuticals was established in 1994. The CRP aimed at developing and improving existing laboratory protocols for the production of therapeutic radionuclides using existing nuclear research reactors including the corresponding radiolabelling, quality control procedures; and validation in experimental animals. With the participation of ten scientists from IAEA Member States, several laboratory procedures for preparation and quality control were developed, tested and assessed as potential therapeutic radiopharmaceuticals for bone pain palliation. In particular, the CRP optimised the reactor production of {sup 153}Sm and the preparation of the radiopharmaceutical {sup 153}Sm-EDTMP (ethylene diamine tetramethylene phosphonate), as well as radiolabelling

    Livestock are an important and integral part of most farming systems in Africa. Recent nutritional research has demonstrated the possibility of substantial increases in the productivity of milk-producing animals fed poor quality roughages through small alterations to the feed base. In some cases, improvements have been demonstrated at the farm level: milk yield has increased, body condition of the animals has improved and age at puberty and the interval between calvings have been reduced. These advances have been brought about by the addition of critical nutrients to the diet, e.g. nitrogen or minerals for the rumen micro-organisms or rumen non-degradable protein or all of these. The introduction of improved feeding practices such as strategic supplementation using locally available feed resources (e.g. tree legume leaves, brewers waste, fish waste, multinutrient blocks, etc.) will not only enhance milk production but will also introduce a sustainable fanning practice that will ensure a continuous supply of milk and milk products to local populations. To introduce effective supplementation there is a need to identify the nutrient or combination of nutrients that are the limiting factors for achieving optimum rumen fermentative digestion of the basal diet or the efficiency of utilization of the major products of digestion. In many of the dairying systems operating in Africa this is far from easy, mainly because of the difficulties encountered in effectively measuring feed intake and selection and the efficiency with which the nutrients absorbed are used for productive purposes. In order to circumvent these difficulties it may be possible to measure biochemical indicators in the cows themselves that provide an assessment of nutrient status. The specific objectives of the co-ordinated research project (CRP) were to: - btain baseline information on production and reproductive parameters using a comprehensive survey, progesterone radioimmunoassay and clinical

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

    Many tumour marker assays have been reported over the years and their role is well recognized and acknowledged in the follow-up of known cancer cases. However, their true potential for use in primary diagnosis or screening of high risk groups is still to be fully realized due to the need to achieve better specificity. Among the various tumour markers, the one for prostate cancer - prostate specific antigen (PSA) - appears to have better specificity, coming close to a tumour specific antigen. Prostate cancer is a commonly encountered cancer in men, and can be effectively treated if detected early. PSA levels in serum appear to provide good correlation with tumour burden. Estimation of free PSA in serum is reported to further improve the diagnosis. In several developed countries routine screening of men above 50 years of age for prostate cancer using serum PSA as marker is recommended. Radioimmunometric assay techniques offer themselves as attractive candidates for measurement of tumour markers. They are robust, economical and didactic, thus eminently suitable for technology transfer, training and teaching. Preparation of primary reagents is relatively easy. The methodology is flexible. As a result of co-operation projects of the IAEA, many developing Member States have built up indigenous capabilities to perform radioimmunometric assays, which can be extended to development of kits for tumour marker assays. Considering the need for indigenous development of capabilities to produce reliable kits for radioimmunometric assays for PSA, in 1997 the IAEA initiated a Co-ordinated Research Project (CRP) on Development of Kits for Radioimmunometric Assays for Tumour Markers. Even though the focus of the project was PSA, it was expected that the expertise to be gained by the participants would also help them undertake development of kits for other tumour markers, essentially using the same methodology. Ten laboratories from Europe, Asia, Africa and the Americas participated

    Artificial insemination (AI) is widely used for improvement of cattle production in developed countries. Its use in developing countries is less widespread and the results obtained are far from satisfactory. Under tropical small-farm conditions, a number of socio-economic, organizational, biological and technical factors make the service more difficult to provide and also less efficient. If the major constraints can be identified and overcome, this technology would become more widely adopted and contribute to an increased production of milk and meat, leading to better food security and poverty alleviation. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture therefore convened a consultants meeting in May 1994 to advise on the applicability of radioimmunoassay (RIA) for measuring progesterone in milk of dairy cattle to identify the major causes of conception failure and reproductive wastage when AI is used under the conditions prevailing in developing countries. The consultants recommended the initiation of a co-ordinated research project (CRP) on this topic, and developed a comprehensive technical document including the sampling protocol and the range of information that needs to be recorded in order to obtain conclusive results. A five year CRP on the ''Use of RIA and Related Techniques to Identify Ways of Improving Artificial Insemination Programmes for Cattle Reared Under Tropical and Sub-Tropical Conditions'' was initiated in early 1995. The CRP resulted in the development and standardization of methodologies and protocols, including the computer software program termed AIDA (Artificial Insemination Database Application), to determine current status and identify constraints. These methodologies and protocols are now being applied on a wider scale in Member States through regional TC projects in Asia and Africa and country TC projects in Latin America.

    2001-04-01

    99m Tc radiopharmaceuticals have remained the workhorse of diagnostic nuclear medicine over the last three decades ever since the introduction of the gamma camera as the main imaging instrument. Due to the near ideal nuclear properties such as gamma energy, half-life, lack of beta radiation and easy availability as a convenient generator system at an affordable cost of 99m Tc, it can be reasonably anticipated that 99m Tc will continue to retain this position in the foreseeable future. To a large extent this has been possible because of the successful development, over the years, of 99m Tc radiopharmaceuticals as substitutes for other clinically well established agents. Examples of these success stories are 99m Tc substitutes for 131 I hippuran and rose bengal 201 Tl and 123 I brain perfusion agents, which have come to be known collectively as 'second generation 99m Tc radiopharmaceuticals'. It should be acknowledged that each one of these developments was a result of innovative and sustained research and development efforts by scientists from different parts of the world. Concurrently these research efforts have made significant contributions to better understanding of the radiochemistry and co-ordination chemistry of 99m Tc. The radiopharmaceutical scientists are now in a much better position to design, prepare and evaluate 99m Tc complexes for specific applications. Building on this capability, the next step is development of 99m Tc substitutes for receptor specific radiopharmaceuticals, which have established clinical potential. Efforts in this direction are already ongoing and the work during the last decade on 99m Tc labelling of monoclonal antibodies can be considered the beginning of these 'third generation 99m Tc radiopharmaceuticals'. The International Atomic Energy Agency (IAEA) had organized two co-ordinated research projects (CRPs) in the past covering 99m Tc second generation agents and 99m Tc monoclonal antibodies, and the results were published in

The CRP could investigate alternate biochemical pathways, promising recent advances in 99 mTc labelling methodologies and recent progress in evaluation methods. Based on recommendations of two consultants meetings, the IAEA initiated a CRP entitled Development of Kits for 99 mTc Radiopharmaceuticals for Infection Imaging in 2000. Twelve laboratories from Asia, Europe, North America, and South America participated in the CRP, which was concluded in 2003. Among the objectives of this CRP was the development of different 99 mTc labelling strategies in participating laboratories that would be useful in the development of 99 mTc labelled infection imaging agents. In addition, techniques were to be developed for the in vitro and in vivo testing of label stability. Finally, it was hoped that one or more of the identified agents would prove to localize in infection by a specific mechanism. The CRP may be said to be successful in all three measures. Finally, with the identification of 99 mTc ubiquicidine fragment (UBI 29-41) as a radiolabelled agent with potential clinical utility, this CRP can be considered to have made a major contribution by providing the first validated specific 99 mTc labelled infection imaging agent

    This publication results from the second Co-ordinated Research Project (CRP) on Plant Breeding and Genetics organized on a regional basis in Latin America. The present CRP and the previous one were initiated and implemented in response to the pressing need to enhance the productivity of economic plants, viz. food crops, fruits and ornamentals. Improvement of crop production has become the highest priority in most countries of Latin America, as in other regions. Breeding superior varieties is often the only feasible solution where inputs are limited; well adapted varieties are required to meet specific agro-environmental conditions. Such varieties provide yield stability on an economically required level. The most important and common factors limiting crop production are abiotic, e.g. cold, salinity, soil aluminium toxicity and drought; as well as biotic, e.g. diseases and pests. Modern biotechnology and induced mutations offer new means and significant potential to breed desired varieties in a relatively short time. Additionally, both approaches facilitate the breeding of some vegetatively propagated crops which until now were improved mainly through selection of rare spontaneous mutants in natural or cultivated populations. Using some of these techniques it recently became possible to produce, in some crops, true-to-type mutated lines or clones within a few months. Biotechnology can also facilitate selection, description and molecular characterization of promising mutants. Currently used DNA markers, such as restriction fragment length polymorphism (RFLP), random amplified polymorphic DNA (RAPD) as well as other polymerase chain reaction (PCR)-based techniques, were included in this CRP to benefit the important crops of this region. Also included in this CRP were doubled haploids (DH), which are obtained from anther or microspore cultures and are very suitable biotechnology methods.

    The rearing of tsetse flies for the sterile insect technique has been a laborious procedure in the past. The purpose of this co-ordinated research project (CRP) 'Automation for tsetse mass rearing for use in sterile insect technique programmes' was to develop appropriate semiautomated procedures to simplify the rearing, reduce the cost and standardize the product. Two main objectives were accomplished. The first was to simplify the handling of adults at emergence. This was achieved by allowing the adults to emerge directly into the production cages. Selection of the appropriate environmental conditions and timing allowed the manipulation of the emergence pattern to achieve the desired ratio of four females to one male with minimal un-emerged females remaining mixed with the male pupae. Tests demonstrated that putting the sexes together at emergence, leaving the males in the production cages, and using a ratio of 4:1 (3:1 for a few species) did not adversely affect pupal production. This has resulted in a standardized system for the self stocking of production cages. The second was to reduce the labour involved in feeding the flies. Three distinct systems were developed and tested in sequence. The first tsetse production unit (TPU 1) was a fully automated system, but the fly survival and fecundity were unacceptably low. From this a simpler TPU 2 was developed and tested, where 63 large cages were held on a frame that could be moved as a single unit to the feeding location. TPU 2 was tested in various locations, and found to satisfy the basic requirements, and the adoption of Plexiglas pupal collection slopes resolved much of the problem due to light distribution. However the cage holding frame was heavy and difficult to position on the feeding frame and the movement disturbed the flies. TPU 2 was superseded by TPU 3, in which the cages remain stationary at all times, and the blood is brought to the flies. The blood feeding system is mounted on rails to make it

    2001-05-01

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

    Significant successes have been made over recent years in preparing co-ordination framework polymers that show macroscopic material properties, but in the vast majority of cases this has been achieved with d-block metal-based systems. Lanthanide co-ordination frameworks also offer attractive properties in terms of their potential applications as luminescent, non-linear optical and porous materials. However, lanthanide-based systems have been far less studied to date than their d-block counterparts. One possible reason for this is that the co-ordination spheres of lanthanide cations are more difficult to control and, in the absence of design strategies for lanthanide co-ordination frameworks, it is significantly more difficult to target materials with specific properties. However, this article highlights some of the exciting possibilities that have emerged from the earliest investigations in this field with new topological families of compounds being discovered from relatively simple framework components, including unusual eight, seven and five-connected framework systems. Our own research, as well as others, is leading to a much greater appreciation of the factors that control framework formation and the resultant observed topologies of these polymers. As this understanding develops targeting particular framework types will become more straightforward and the development of designed polyfunctional materials more accessible. Thus, it can be seen that lanthanide co-ordination frameworks have the potential to open up previously unexplored directions for materials chemistry. This article focuses on the underlying concepts for the construction of these enticing and potentially highly important materials

    The Co-ordinated research programme on the benchmark study for the seismic analysis and testing of WWER-type nuclear power plants was initiated subsequent to the request from representatives of Member States. The conclusions adopted at the Technical Committee Meeting on Seismic Issues related to existing nuclear power plants held in Tokyo in 1991 called for the harmonization of methods and criteria used in Member States in issues related to seismic safety. The Consulltants' Meeting which followed resulted in producing a working document for CRP. It was decided that a benchmark study is the most effective way to achieve the principal objective. Two types of WWER reactors (WWER-440/213 and WWER-1000) were selected as prototypes for the benchmark exercise to be tested on a full scale using explosions and/or vibration generators. The two prototypes are Kozloduy Units 5/6 for WWER-1000 and Paks for WWER-440/213 nuclear power plants.

    The environmental impact of releases of radionuclides from nuclear installations can be predicted using assessment models. For such assessments information on their reliability must be provided. Ideally models should be developed and tested using actual data on the transfer of the nuclides which are site specific for the environment being modelled. In the past, generic data have often been taken from environmental contamination that resulted from the fallout from the nuclear weapons testing in the 1950s and 1960s or from laboratory experiments. However, it has always been recognized that there may be differences in the physico-chemical form of the radionuclides from these sources as compared to those that could be released from nuclear installations. Furthermore, weapons fallout was spread over time; it did not provide a single pulse which is generally used in testing models that predict time dependence. On the other hand, the Chernobyl accident resulted in a single pulse, which was detected and measured in a variety of environments throughout Europe. The acquisition of these new data sets justified the establishment of an international programme aimed at collating data from different IAEA Member States and at co-ordinating work on new model testing studies. The IAEA established a Co-ordinated Research Programme (CRP) on 'Validation of Environmental Model Predictions' (VAMP). The principal objectives of the VAMP Co-ordinated Research Programme were: (a) To facilitate the validation of assessment models for radionuclide transfer in the terrestrial, aquatic and urban environments. It is envisaged that this will be achieved by acquiring suitable sets of environmental data from the results of the national research and monitoring programmes established following the Chernobyl release. (b) To guide, if necessary, environmental research and monitoring efforts to acquire data for the validation of models used to assess the most significant radiological exposure pathways

    In the Netherlands, youth-care organisations and community sports clubs are collaborating to increase socially vulnerable youths' participation in sport. This is rooted in the idea that sports clubs are settings for youth development. As not much is known about co-ordinated action involving professional care organisations and community sports clubs, this study aims to generate insight into facilitators of and barriers to successful co-ordinated action between these two organisations. A cross-sectional study was conducted using in-depth semi-structured qualitative interview data. In total, 23 interviews were held at five locations where co-ordinated action between youth-care and sports takes place. Interviewees were youth-care workers, representatives from community sports clubs, and Care Sport Connectors who were assigned to encourage and manage the co-ordinated action. Using inductive coding procedures, this study shows that existing and good relationships, a boundary spanner, care workers' attitudes, knowledge and competences of the participants, organisational policies and ambitions, and some elements external to the co-ordinated action were reported to be facilitators or barriers. In addition, the participants reported that the different facilitators and barriers influenced the success of the co-ordinated action at different stages of the co-ordinated action. Future research is recommended to further explore the role of boundary spanners in co-ordinated action involving social care organisations and community sports clubs, and to identify what external elements (e.g. events, processes, national policies) are turning points in the formation, implementation and continuation of such co-ordinated action. © 2017 John Wiley & Sons Ltd.

    1994-08-01

    A co-ordinated research programme was begun at the IAEA in 1988 with the short title of Validation of Environmental Model Predictions (VAMP). The VAMP Urban Working Group aims to examine, by means of expert review combined with formal validation exercises, modelling for the assessment of the radiation exposure of urban populations through the external irradiation and inhalation pathways. An aim of the studies is to evaluate the lessons learned and to document the improvements in modelling capability as a result of experience gained following the Chernobyl accident. This Technical Document, the first report of the Group, addresses the subject of the deposition of airborne radionuclides into the urban environment. It summarizes not only the present status of modelling in this field, but also the results of a limited validation exercise that was performed under the auspices of VAMP. 42 refs, figs and tabs

  7. Use of nuclear and related techniques in studies of agroecological effects resulting from the use of persistent pesticides in Central America. Report of a final research co-ordination meeting

    International Nuclear Information System (INIS)

    1999-09-01

    The use of pesticides for the control of pests of agriculture and vectors of human and animal diseases in the countries of Central America is the highest per capita and one of the most intense in the world. There are reports of acute toxicity and chronic effects among farm workers. There are also reports that pesticide residues in food frequently exceed the Codex Alimentarius Commission's maximum residue levels (MRLs) and shipments of foodstuffs have been rejected by importing countries due to the presence of excessive residues of pesticides. Pesticides are also implicated in the contamination of continental and coastal waters. The indiscriminate use of pesticides would be expected to also aggravate pest problems by adversely affecting populations of beneficial arthropods and causing the development of resistance in pest populations. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated a co-ordinated research project in 1992 to generate information on residues of pesticides in the environment, their persistence under local conditions and effect on local species of beneficial arthropods in agricultural and adjacent areas in the countries of Central America. Such information could be used in the implementation of legislation to control the distribution and use of pesticides and the development and application of integrated pest management programmes. Scientists from Costa Rica, Guatemala, Honduras, Nicaragua, Panama and the United States of America participated in this project. This TECDOC reports on the accomplishments of the project and includes the papers presented at the final Research Co-ordination Meeting held in Panama City, Panama, 20-24 April 1998

    At the request of the IAEA, the authors have performed an assessment of the analytical quality and the interpretation of the trace element data obtained within the framework of the IAEA Co-ordinated Research Programme (CRP) on The Significance of Hair Mineral Analysis as a Means of Assessing Internal Body Burdens of Environmental Pollutants. In this CRP research groups from various countries participated, using different analytical procedures, based on NAA, XRF and AAS. Data have been collected for Zn, CU, Pb, Cd, As, Hg, and Se in male human hair, liver, kidney, lung, brain, and bone. The samples analyzed originated from China, Hungary, Bulgaria, Japan, the former GDR, Sweden and Norway. The analytical quality of the data has been assessed on basis of the calculated limits of quantitation per trace element determined, per tissue analyzed and per participant, as well as from the trace element values found for reference materials and ''blind'' materials. The analytical quality of the data differs widely, from generally good to reasonable (Zn, Cu, and Se) to generally inadequate to strongly inadequate (Pb, Cd, As, and Hg). 15 refs, 29 tabs

    The Second Research Coordination Meeting for the Co-ordinated Research Project (CRP) on 'Ingestion and Organ Content of Trace Elements of Importance in Radiological Protection: Reference Asian Man Project, Phase 2' was held at the China Institute for Radiation Protection (CIRP) in Taiyuan, People's Republic of China. During the first technical Session, an overview of the current status of the CRP was presented by the IAEA technical officer, Dr. Parr, and the responsible officer of the Central Reference Laboratory (NIRS, Japan), Dr. Kawamura. They drew attention to the agreed programme of work, as described in the project documentation, and the timetable foreseen for the CRP as summarized in table 1. In general, they concluded that the achievements of the CRP to-date appear to be good, particularly in relation to sample collection (in most countries) and quality control (the development of appropriate reference materials). However, some aspects of the work appear to be a little behind schedule, particularly (1) the final stages of preparation of total diet samples (because of delays in providing a suitable food blender), (2) the analysis of some of the elements of first priority (because of the non-availability, until now, of suitable analytical reference materials), and (3) in some countries, the collection of autopsy specimens. One country (Malaysia) has experienced considerable difficulties in implementing the project due to the retirement of the former Chief Scientific Investigator. For this reason it was unfortunately not possible for the Malaysian representative to be present at the RCM

    The third sector has played a significant role internationally in the delivery of adult social care services for many years. Its contribution to care co-ordination activities for older people, however, in England and elsewhere, is relatively unknown. A scoping review was therefore conducted to ascertain the character of the literature, the nature and extent of third sector care co-ordination activity, and to identify evidence gaps. It was undertaken between autumn 2013 and summer 2014 and updated with additional searches in 2016. Electronic and manual searches of international literature using distinct terms for different approaches to care co-ordination were undertaken. From a total of 835 papers, 26 met inclusion criteria. Data were organised in relation to care co-ordination approaches, types of third sector organisation and care recipients. Papers were predominantly from the UK and published this century. Key findings included that: a minority of literature focused specifically on older people and that those doing so described only one care co-ordination approach; third sector services tended to be associated with independence and person-centred practice; and working with the statutory sector, a prerequisite of care co-ordination, was challenging and required a range of features to be in place to support effective partnerships. Strengths and weaknesses of care co-ordination practice in the third sector according to key stakeholder groups were also highlighted. Areas for future research included the need for: a specific focus on older people's experiences; an investigation of workforce issues; detailed examination of third sector practices, outcomes and costs; interactions with the statutory sector; and an examination of quality assurance systems and their appropriateness to third sector practice. The main implication of the findings is a need to nurture variety within the third sector in order to provide older people and other adults with the range of service

    Although few problems have been reported with cables in normal operation of NPPs, there have been some cases where cables which had initially been qualified for a 40 year service life failed a design basis event test after removal from the plant following less than 10 years of normal operation. This report presents recommendations of Coordinated Research Programmes participants for ongoing qualification and condition monitoring methods that can be used in NPPs to provide additional assurance for the safety of cables inside containment. The report will be of interest to NPP designers, operators, regulators, technical support organizations and researchers interested in electrical and I and C cable qualification programmes. 19 refs, 8 figs, 1 tab

    The International Atomic Energy Agency (IAEA) supports Member State activities in the area of advanced fast reactor technology development by providing a forum for information exchange and collaborative research programmes. The Agency's activities in this field are mainly carried out within the framework of the Technical Working Group on Fast Reactors (TWG-FR), which assists in the implementation of corresponding IAEA activities and ensures that all technical activities are in line with the expressed needs of Member States. Among its broad range of activities, the IAEA proposes and establishes coordinated research projects (CRPs) aimed at the improvement of Member State capabilities in the area of fast reactor design and analysis. An important opportunity to undertake collaborative research was provided by the experimental campaign of the French Alternative Energies and Atomic Energy Commission (CEA) in the prototype sodium fast reactor PHENIX before it was shut down in 2009. The overall purpose of the end of life tests was to gather additional experience on the operation of sodium cooled reactors. As the CEA opened the experiments to international cooperation, in 2007 the IAEA launched a CRP on ''Control Rod Withdrawal and Sodium Natural Circulation Tests Performed during the PHENIX End-of-Life Experiments''. The CRP, with the participation of institutes from eight countries, contributed to improving capabilities in sodium cooled reactor simulation through code verification and validation, with particular emphasis on temperature and power distribution calculations and the analysis of sodium natural circulation phenomena. The objective of this report is to document the results and main achievements of the benchmark analyses on the natural circulation test performed in the framework of the PHENIX end of life experimental campaign

  9. Collection and classification of human reliability data for use in probabilistic safety assessments. Final report of a co-ordinated research programme 1995-1998

    International Nuclear Information System (INIS)

    1998-10-01

    One of the most important lessons from abnormal events in NPPs is that they often result from incorrect human action. The awareness of the importance of human factors and human reliability has increased significantly over 10-15 years primarily owing to the fact that some major incidents (nuclear or non-nuclear) have had significant human error contributions. Each of these incidents have revealed different types of human errors, some of which were not generally recognized prior to the incident. The analysis of these events led to wide recognition of the fact that more information about human actions and errors is needed to improve the safety and operation of nuclear power plants. At the same time, the need or proper human reliability data was recognised in view of probabilistic safety assessment (PSA). No PSA study can be regarded as complete and accurate without adequate incorporation of human reliability analysis (HRA). In order to support incorporation of human reliability data into PSA the IAEA established a coordinated research programme with the objective to develop a common data base structure for human errors that might have important contributions to risk in different types of reactors. This report is a product of four years of coordinated research and describes the data collection and classification schemes currently in use in Member States as well as an outlook into future, discussing what types of data might be needed to support the new improved HRA methods which are currently under development

  10. Study of the impact of food irradiation on preventing losses: Experience in Africa. Proceedings of a final research co-ordination meeting

    International Nuclear Information System (INIS)

    2002-05-01

    There have been positive developments on food irradiation in different regions of the world, especially in the United States of America and several Asian and Latin American countries. In some countries in Africa, this technology has been studied in the past few decades with encouraging results. To assist these countries in conducting pilot scale research and development on irradiation of specific commodities of interest to them including market testing and feasibility to establish commercial irradiators for multi-purpose application, a Coordinated Research Project (CRP) on Impact of Irradiation to Prevent Food Losses in Africa was carried out between 1995 and 1999. This CRP demonstrated that food irradiation has a potential to reduce losses of basic staple food crops including yams, dried and smoked fish, potatoes and onions through pilot scale experiments carried out in some African countries. Small scale market testing of such irradiated food such as spices, potatoes and onions showed encouraging results. In some countries (Cote d'Ivoire, Egypt, Ghana, Senegal and South Africa), it is feasible to establish commercial irradiation facilities for treating food. In Morocco, irradiation shows a potential to meet quarantine requirements in international food trade. It should be noted that commercial scale application of irradiation of some food products has been carried out in South Africa since the 1980s

    2000-01-01

    One of the tasks of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture is to promote the use of nuclear techniques for improving disease diagnosis and monitoring disease control programmes in order to optimise animal production in developing countries. An applied research programme was initiated in 1987 with funding from the Government of the Netherlands to validate an ELISA to detect trypanosomal antigens developed by the International Laboratory for Research on Animal Diseases (ILRAD). The test was successfully validated in ten different laboratories in Africa through a Co-ordinated Research Programme (CRP) from 1987-1993 entitled ''Improving the diagnosis and control of trypanosomosis and other vector-borne diseases of African livestock using immunoassay methods''. Results indicated a reasonable, but at times variable sensitivity and specificity (published in IAEA-TECDOC-707). During an additional two-year period (1993-1995) the IAEA Department of Technical Co-operation and the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture provided support for a Regional Technical Co-operation Project (TCP) to strengthen disease diagnostic capabilities in the National Agricultural Research Systems (NARS) with a special emphasis on the diagnosis of trypanosomosis. Results of the TCP were published in IAEA-TECDOC-925 and were encouraging enough to request additional funding from the Government of the Netherlands for a five-year programme to enable application of the assay as a tool for monitoring disease control programmes in Africa. The results of the latter programme are reported in the present publication together with a number of review articles on the diagnostic and epidemiological aspects of the disease in African livestock

  13. Benchmark study for the seismic analysis and testing of WWER type NPPs. Final report of a co-ordinated research project

    International Nuclear Information System (INIS)

    2000-10-01

    This report is the final results of a five-year IAEA Coordinated Research Project (CRP) launched in 1992. The main goal was the harmonization of criteria and methods used in Member States in seismic reassessment and upgrading of existing nuclear power plants. To this aim, most of the activities have been focused on a benchmarking exercise related to a mixed numerical and experimental dynamic analysis carried out on two reference units of WWER reactors (WWER-1000 and WWER-440/213): Kozloduy NPP Units 5/6 and PAKS NPP. Twenty-four institutions from 13 countries participated in the CRP, and two other institutions from Japan contributed to the CRP informally. The objective of this TECDOC is to provide a consistent and comprehensive summary of the results of the work performed in the CRP through the preparation of a ''self-standing'' report with the general conclusion of the programme: a great deal of information from the Background Documents has been included in this report with a set of recommendations for future work in this field

    Full text: The main objective of the study was to determine the therapeutic efficacy of radiosynovectomy. Rheumatoid arthritis is a Chronic or sub-acute, systemic inflammatory disorder principally involving the joints with peripheral symmetrical inflammatory non-suppurative arthritis. It usually has a prolonged course with relapse and remissions. Haemophilia is a congenital blood disease that produces abnormal bleeding at musculoskeletal level. The origin of this abnormal bleeding is the lack of a coagulation factor, Factor VIII for haemophilia A and Factor IX for haemophilia B or Christmas disease. The overall goals of therapy in rheumatoid arthritis are: alleviation of pain, control of disease activity, slowing down the rate of damage and improvement in the quality of life. On the other hand the aim of the orthopaedic treatment in haemophilic haemarthrosis is to avoid recurrence of the haemarthrosis by acting on the synovial membrane, by fibrosing it, in addition to pain alleviation and improving the quality of life. Radionuclide therapy, commonly known as 'Radiosynovectomy', is a very useful procedure, which if used appropriately may form an effective tool in the management of rheumatoid arthritis and haemophilic haemoarthropathy. With the help received from the IAEA under the auspices of a coordinated research project, for the first time in our hospital we introduced radiosynovectomy in the year 2003. Until now, a total number of 40 patients of rheumatoid arthritis and one patient of haemophilic arthritis have been treated following a protocol designed by the IAEA under the CRP. The diagnosis of rheumatoid arthritis and haemophilic arthropathy was established by standard well established findings of clinical examination and laboratory investigations. All patients underwent a two phase bone soft tissue scintigraphy to assess the inflammatory activity in the joints prior to therapy. A radiosynovectomy team was formed in the hospital consisting of a nuclear

    The British Geological Survey is reponsible for co-ordinating the Department of the Environment's programme of natural analogue studies of radionuclide migration, a research programme that involved both UK and overseas sites. Co-ordination is achieved through the UK Natural Analogue Co-ordinating Group (NACG) which was established in October 1986. It has met three times to date and its function is to ensure that the different research projects have an integrated purpose aimed at improving and applying our understanding of natural geochemical processes in a way that will increase our confidence in long-term modelling predictions. Improved modelling prediction of radionuclide transport in the geosphere will directly benefit the performance and safety assessments of proposed radioactive waste repositories. (author)

  16. Final report of the FAO/IAEA co-ordinated research project on the use of nuclear and related techniques for evaluating the agronomic effectiveness of phosphate fertilisers, in particular rock phosphates

    International Nuclear Information System (INIS)

    Zapata, F.

    1999-02-01

    Soils in developing countries are often deficient in available P, and therefore require inputs of P fertiliser for optimum plant growth and production of food and fibre. Due to economic considerations, the cost of applying imported or locally produced water-soluble P fertilisers is often more expensive than utilising indigenous phosphate rock. Phosphate rocks show large differences in their suitability for direct application and several factors influence their capability to supply phosphorus to crops. Therefore, quantifying the P availability of soils amended with phosphate rocks in a variety of crop management and environmental conditions in developing countries is imperative for making recommendations on the best type and rate of P fertiliser sources for maximum agronomic and economic benefits. P-32 isotope techniques are very useful for such studies. The background situation of phosphate research and the topics to be investigated using isotope techniques were critically examined in a Consultants Meeting held at the IAEA Headquarters, Vienna, Austria, from 10 to 12 May 1993. For detailed information please refer to IAEA Report CT-1112. Based on the recommendations of this Consultants' Meeting, the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture with the generous support of the French Government decided to implement the Co-ordinated Research Project (CRP) on 'The Use of Nuclear and Related Techniques for Evaluating the Agronomic Effectiveness of Phosphate Fertilisers, in particular Rock Phosphates'.

    The traceability of dose measurements to the international measurement system in a few developed countries is ensured through national hierarchies of primary and secondary standards dosimetry laboratories, and in the rest of the world through the network of SSDLs maintained by the IAEA and WHO. The role of the SSDLs is crucial in providing traceable calibrations with the goal of achieving an uncertainty of the therapy level calibration factors of the order of about 1%. The SSDLs should also play an important role in the global efforts to provide quality audits to radiotherapy centres. While every SSDL would be expected to run an appropriate quality system, the quality standards require that this system should be well documented in the form of a quality manual. A documented quality system will clearly be a requirement when a laboratory wishes to apply for the accreditation of its calibration and testing activities or for the certification of its quality system. The quality system of an SSDL should cover all the work carried out by the laboratory, whether this is the calibration of dosimeters, measurements for quality audits at radiotherapy clinics or for other demands of, for example, industrial customers. The implementation of the quality system requires high commitment of all staff members of the SSDL and can only be achieved through well organized and documented team work. A Co-ordinated Research Project (CRP E2.10.02) was initiated by the Agency with the objective to develop guidelines for SSDLs of the IAEA/WHO network. The guidelines should cover the establishment of a quality system and practical recommendations for the preparation of a quality manual, following ISO/IEC Standards. In addition, a harmonized programme for quality control of the standards, calibration equipment and calibration procedure will be proposed

    The Oak Ridge Operations Office of the USAEC has within its jurisdiction multiple contractors and facilities for research and for the production of fissile materials for the atomic energy programme. Among these facilities are gaseous diffusion plants for the production of {sup 235}U-enriched uranium hexafluoride, plants for the fabrication of special components and fuel for research and production reactors, and laboratories for pilot plant studies and basic research in nuclear technology. One research laboratory is also actively engaged in criticality experimental programmes and has been a major contributor of criticality data for safety applications. These diversified programmes include the processing, fabrication and transport of practically all forms and isotopic enrichments of uranium in quantities commensurate with both laboratory and volume production requirements. Consequently, adequate nuclear safety control with reasonable economy for operations of this magnitude demands not only co-ordination and liaison between contractor and USAEC staffs, but a continuing reappraisal of safety applications in light of the most advanced information. This report outlines the role of the Oak Ridge Operations Office in these pursuits and describes as examples some specific problems in which this office co-ordinated actions necessary for their resolution. Other examples are given of parametric and procedural applications in plant processes and fissile shipments emphasizing the use of recent experimental or calculated data. These examples involve the use of mass and geometric variables, neutron absorbers and moderation control. Departures from limits specified in existing nuclear safety guides are made to advantage in light of new data, special equipment design, contingencies and acceptable risks. (author)

    Under which conditions does the open method of co-ordination match the standards for demoi-cracy? To answer this question, we need some explicit standards about demoi-cracy. In fact, open co-ordination serves three different but interrelated purposes in European Union policy: to facilitate...... convergence; to support learning processes; and to encourage exploration of policy innovation. By intersecting standards and purposes, we find open co-ordination is neither inherently ‘good’ nor ‘bad’ for demoi-cracy, as it depends on how it has been put into practice. Therefore, we qualify the answer...

    2004-07-01

    For several decades, countries have made use of near surface facilities for the disposal of low and intermediate level radioactive waste. In line with the internationally agreed principles of radioactive waste management, the safety of these facilities needs to be ensured during all stages of their lifetimes, including the post-closure period. By the mid 1990s, formal methodologies for evaluating the long term safety of such facilities had been developed, but intercomparison of these methodologies had revealed a number of discrepancies between them. Consequently, in 1997, the International Atomic Energy Agency launched a Co-ordinated Research Project (CRP) on Improvement of Safety Assessment Methodologies for Near Surface Disposal Facilities (ISAM). The particular objectives of the CRP were to provide a critical evaluation of the approaches and tools used in post-closure safety assessment for proposed and existing near-surface radioactive waste disposal facilities, enhance the approaches and tools used and build confidence in the approaches and tools used. The CRP ran until 2000 and resulted in the development of a harmonized assessment methodology (the ISAM project methodology), which was applied to a number of test cases. Over seventy participants from twenty-two Member States played an active role in the project and it attracted interest from around seven hundred persons involved with safety assessment in seventy-two Member States. The results of the CRP have contributed to the Action Plan on the Safety of Radioactive Waste Management which was approved by the Board of Governors and endorsed by the General Conference in September 2001. Specifically, they contribute to Action 5, which requests the IAEA Secretariat to 'develop a structured and systematic programme to ensure adequate application of the Agency's waste safety standards', by elaborating on the Safety Requirements on 'Near Surface Disposal of Radioactive Waste' (Safety Standards Series No. WS-R-1) and

    The International Atomic Energy Agency (IAEA) is actively contributing through coordinated research project mechanisms to the development of isotopic techniques applicable for pollution-nutrition interactions. This CRP is based on the recommendations of a consultants' meeting on: 'Nuclear Analytical and Isotope Techniques for assessing nutrition-pollution interactions', NAHRES-62. The main objective of the CRP is to provide a scientific basis for better assessment of selected pollutants and nutrients in biological samples with a view to elucidate their interactions and the impact on human health. Results of this study will enhance the existing body of knowledge on nutrition-pollution interactions mechanisms and can be used to develop preventive strategies. SPECIFIC OBJECTIVES: Use of non-invasive specimens (e.g. breast milk, blood, hair, urine, placenta, eventually adipose tissue for organic pollutants) as indicators to monitor the interaction between the environmental pollution (both organic and inorganic) and nutritional status. Development of protocols to assess the health impact of environmental conditions on populations living under the risk of malnutrition. Validated procedures for chemical analysis in selected environment and nutritional specimens for research in the pollutant-nutrition interaction

    Helicobacter pylori has been recognized as a major etiologic factor in the development of chronic gastritis and peptic ulcer disease in adults and children. The infection has been linked to the development of gastric cancer, and in 1994 was classified as a group 1 carcinogen by the International Agency for Research on Cancer. The prevalence of H. pylori infection is inversely correlated to the socio-economic development and to unsatisfactory prevailing sanitary conditions. In developing countries, up to 90% of the adult population is colonized with this agent. In contrast, its prevalence in developed countries is lower, ranging from 25 to 50%. H. pylori colonization has been considered a public health problem, since its highest incidence occurs during the first few years of life, when children are growing and developing rapidly. The acquisition of the infection occurs mainly in early childhood, especially in developing countries, but the age at which it is acquired remains unknown. Infection with H. pylori during early infancy could be the initial step of a reaction which facilitates enteric infection in childhood leading to recurrent diarrhoea, malnutrition and growth failure. Micronutrient deficiencies resulting from these conditions may in turn facilitate malnutrition, immunological dysfunction and the persistence of infection. The {sup 13}C-urea breath test ({sup 13}C-UBT), which has been used extensively in developed countries, is a technique that is non invasive, reliable, comparatively cheap and without risk to patients. It is also convenient for use in field-based settings; it is currently considered the 'gold standard' against which all other techniques are compared. The International Atomic Energy Agency (IAEA), initiated the current Coordinated Research Project (CRP) with the principal objective of promoting the use of the {sup 13}C-urea breath test technique in the participating countries to study the prevalence of Helicobacter pylori and its impact on

Infection with H. pylori during early infancy could be the initial step of a reaction which facilitates enteric infection in childhood leading to recurrent diarrhoea, malnutrition and growth failure. Micronutrient deficiencies resulting from these conditions may in turn facilitate malnutrition, immunological dysfunction and the persistence of infection. The 13 C-urea breath test ( 13 C-UBT), which has been used extensively in developed countries, is a technique that is non invasive, reliable, comparatively cheap and without risk to patients. It is also convenient for use in field-based settings; it is currently considered the 'gold standard' against which all other techniques are compared. The International Atomic Energy Agency (IAEA), initiated the current Coordinated Research Project (CRP) with the principal objective of promoting the use of the 13 C-urea breath test technique in the participating countries to study the prevalence of Helicobacter pylori and its impact on health and

    of the XX century suffered a reverse. The designers of the United States' firms and enterprises of aviation and rocket-space industry (Boeing, Rocketdyne, Lockheed Martin, McDonnell Douglas, Rockwell, etc.) and NASA (Marshall Space Flight Center, Johnson Space Center, Langley Research Center and Lewis Research Center and others) could not correctly co-ordinate the characteristics of a propulsion system and a space vehicle for elaboration of the "Single-Stage-To-Orbit" reusable vehicle (SSTO) as an integral whole system, which is would able to inject a payload into an orbit and to return back on the Earth. jet nozzle design as well as the choice of propulsion system characteristics, ensuring the high ballistic efficiency, are considered in the present report. The efficiency criterions for the engine and launch system parameters optimization are discussed. The new methods of the nozzle block optimal parameters' choice for the satisfaction of the object task of flight are suggested. The family of SSTO with a payload mass from 5 to 20 ton and initial weight under 800 ton is considered.

    The local liquid structure around heterovalent cation impurities in molten chlorides is discussed in relation to spectroscopic data on solutions of transition metal ions. A tightly packed, low co-ordination shell is shown to be favoured by Coulomb ionic interactions for physically reasonable values of the size of the impurity. A competition between these forces and ''crystal field'' interactions favouring octahedral co-ordination is thus to be expected for many transition metal ions, as suggested by Gruen and McBeth. The transition observed for some transition metal ions from higher to lower co-ordination with increasing temperature is attributed primarily to entropy differences, that are roughly estimated in a solid-like model.

    The sixth workshop of the OECD/NEA Forum on Stakeholder Confidence (FSC) was hosted by ENRESA, the Spanish agency responsible for the management of radioactive waste and the dismantling of nuclear power plants, and the Council of Nuclear Safety (CSN), with the support of the Association of Spanish Municipalities in Areas Surrounding Nuclear Power Plants (AMAC). The workshop took place at L'Hospitalet de l'Infant, Catalonia, Spain, on 21-23 November 2005. At this workshop, Spanish stakeholders and delegates from 14 countries discussed current co-ordination of radioactive waste management decision making in Spain. Findings were shared from Cowam-Spain, a co-operative research project on the involvement of local stakeholders, the relationship between national and local levels of decision making, and the long-term sustainability of decisions regarding the siting of a centralized interim storage facility for high-level waste. These proceedings include the workshop presentations and discussions, as well as the rapporteurs' reflections on what was learned about policy making and participative decision making. (author)

    In 1994, a group of consultants was asked to advice the Agency on the expansion of the IAEA/WHO TLD postal dose check service for radiotherapy hospitals by transfer of know-how to national level. The consultants advised the Agency to initiate the Co-ordinated Research Programme (CRP) to transfer the IAEA well established TLD methodology to the countries where existing resources enable set up of the External Audit Groups - nationally recognised groups in charge of operating external quality audits for radiotherapy dosimetry. The External Audit Groups (EAG) include the SSDL, a Measuring Centre (MC) and a Medical Physics Group (MPG), and these groups work in close co-operation during all steps of the TLD audits

    coordinated research programmes was the multi-centre trial of Infecton involving eight countries, Argentina, Chile, Egypt, Greece, India, Indonesia, Singapore and the UK. A total of 879 patients were studied. There were in total 574 positive studies and 295 negative studies with an overall sensitivity of 85.4% and specificity of 81.7% for detecting infective foci. The investigators confirmed the robustness of the preparation, ease of imaging and the absence of side effect. It also concluded that serial imaging with Infecton was useful in monitoring clinical responses and optimising the duration of antimicrobial treatment. The present strategy is to use white cell imaging and non-specific imaging with HIG and liposomes for first line approach and reserve the more specific agents for targeted clinical decisions. The use liposomes could be particularly important for assessment and delivery of pharmacologically active material at selective sites such as during fungal infection involving HIV patients. This approach may aide decisions related to toxicity and usefulness of expensive medicines such as the anti-fungal. Therefore, the Agency has a broad and strategic role in the use of radioisotope techniques for assisting many Member States with infection control programmes. (author)

    1999-01-01

    With most Newly Independent States (NIS) of the former Soviet Union becoming parties to the Non-Proliferation Treaty as Non-Nuclear Weapon States, there has been an acute need in these states for considerable assistance for the establishment of the necessary structure and resources to ensure that their commitments to non-proliferation are fully implemented in a timely manner. A number of IAEA Member States have offered and are now providing assistance to the NIS on a bilateral level to set up an appropriate State System of Accounting and Control (SSAC) which includes Import/Export Control and Physical Protection of Nuclear Material in each state. The IAEA and these Member States established the Co-ordinated Technical Support Programme (CTSP) to ensure that the support given to the NIS was done in a co-ordinated and transparent manner and to avoid duplication of effort. The IAEA has played a coordinating role for the past 5 years by helping to identify detailed needs in individual States, by providing a platform for Member States to identify areas where they could provide the optimum support, and in developing and preparing the Co-ordinated Technical Support Plans. The IAEA organises annual meetings in Vienna attended by all donor and recipient countries to review the focus and implementation status of the co-ordinated technical support activities. A position statement is made by each donor and recipient country, and views and experiences are exchanged. The contents of the CTSPs and the role of the Agency in monitoring the progress of the individual tasks are reviewed in this paper. A summary comparing the implementation status of the Programme by each country is presented. (author)

    International Nuclear Information System (INIS)

    2012-01-01

    Experts from the participating IAEA Member States presented their individual reports on their activities on Neutron Imaging (NI) as well as on Cultural Heritage (CH) studies. The participants also presented an overview of their facilities, ranging from conventional to advanced, and their plans for implementing or improving NI. From the presentations of the delegates it is evident that the current existing NI technology provides a unique non-destructive bulk analytical capability to the CH community. This technology entails 2-dimensional and 3-dimensional results, and is available at about 16 well equipped facilities throughout the world.The presentations also reported new techniques under development in NI which will be capable to further support the needs expressed by the CH community. These techniques expand the capability of the existing NI technology in the field of structural, chemical and elemental analysis. The CH-community favours non-invasive techniques to characterize their research objects, which include irreplaceable unique findings recovered from Archaeological-, Palaeontologic-, Human evolution- and Historical sites. Answers needed include identification of ancient manufacturing technology, detection of hidden features and objects, mensuration, authentication, provenance and identification of the best ways of conservation, etc. The experts welcome the initiation of a CRP to harmonize selected Neutron-based Imaging techniques in order to provide state-of-the-art end user services in the area of CH research. The CRP promotes NI technology utilization in all Member States, especially those in developing countries in order to encourage exploitation of all types of neutron sources for NI through CH research activities. These activities will establish and strengthen collaborations between the NI specialists and researchers from the CH community beyond the 3-year lifetime of this project. Standardization procedures and methodologies were addressed to achieve

    The organic compound 1,8-dibromooctane (1,8-DBO) exists in liquid phase at ambient temperatures and has versatile synthetic applications. In its liquid phase 1,8-DBO has been expected to exist in four most probable conformations, with all its carbon atoms in the same plane, having symmetries C 2h , C i , C 2 and C 1 . In the present study a detailed vibrational analysis in terms of assignment of Fourier transform infrared (FT-IR) and Raman bands of this molecule using normal co-ordinate calculations has been done. A systematic set of symmetry co-ordinates has been constructed for this molecule and normal co-ordinate analysis is carried out using the computer program MOLVIB. The force-field transferred from already studied lower chain bromo-alkanes is subjected to refinement so as to fit the observed infrared and Raman frequencies with those of calculated ones. The potential energy distribution (PED) has also been calculated for each mode of vibration of the molecule for the assumed conformations.

    This article describes an experience of thematic analysis. In order to answer the question 'What does analysis look like in practice?' it describes in brief how the methodology of grounded theory, the epistemology of social constructionism, and the theoretical stance of symbolic interactionism inform analysis. Additionally, analysis is examined by evidencing the systematic processes--here termed organising, coding, writing, theorising, and reading--that led the researcher to develop a final thematic schema.

    The objective of this paper is to describe two methods of qualitative analysis - thematic analysis and content analysis - and to examine their use in a mental health context. A description of the processes of thematic analysis and content analysis is provided. These processes are then illustrated by conducting two analyses of the same qualitative data. Transcripts of qualitative interviews are analysed using each method to illustrate these processes. The illustration of the processes highlights the different outcomes from the same set of data. Thematic and content analyses are qualitative methods that serve different research purposes. Thematic analysis provides an interpretation of participants' meanings, while content analysis is a direct representation of participants' responses. These methods provide two ways of understanding meanings and experiences and provide important knowledge in a mental health context. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    In order to plan accurate motor actions, the brain needs to build an integrated spatial representation associated with visual stimuli and haptic stimuli. Since visual stimuli are represented in retina-centered co-ordinates and haptic stimuli are represented in body-centered co-ordinates, co-ordinate transformations must occur between the retina-centered co-ordinates and body-centered co-ordinates. A spiking neural network (SNN) model, which is trained with spike-timing-dependent-plasticity (STDP), is proposed to perform a 2D co-ordinate transformation of the polar representation of an arm position to a Cartesian representation, to create a virtual image map of a haptic input. Through the visual pathway, a position signal corresponding to the haptic input is used to train the SNN with STDP synapses such that after learning the SNN can perform the co-ordinate transformation to generate a representation of the haptic input with the same co-ordinates as a visual image. The model can be applied to explain co-ordinate transformation in spiking neuron based systems. The principle can be used in artificial intelligent systems to process complex co-ordinate transformations represented by biological stimuli.

    2005-01-01

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

    2005-05-01

    Mammography is an extremely useful non-invasive imaging technique with unparalleled advantages for the detection of breast cancer. It has played an immense role in the screening of women above a certain age or with a family history of breast cancer. The IAEA has a statutory responsibility to establish standards for the protection of people against exposure to ionizing radiation and to provide for the worldwide application of those standards. A fundamental requirement of the International Basic Safety Standards for Protection Against Ionizing Radiation (BSS) and for the Safety of Radiation Sources, issued by the IAEA and co-sponsored by FAO, ILO, WHO, PAHO and NEA, is the optimization of radiological protection of patients undergoing medical exposure. In keeping with its responsibility on the application of standards, the IAEA programme on Radiological Protection of Patients attempts to reduce radiation doses to patients while balancing quality assurance considerations. IAEA-TECDOC-796, Radiation Doses in Diagnostic Radiology and Methods for Dose Reduction (1995), addresses this aspect. The related IAEA-TECDOC-1423 on Optimization of the Radiological Protection of Patients undergoing Radiography, Fluoroscopy and Computed Tomography, (2004) constitutes the final report of the coordinated research in Africa, Asia and eastern Europe. The preceding publications do not explicitly consider mammography. Mindful of the importance of this imaging technique, the IAEA launched a Coordinated Research Project on Optimization of Protection in Mammography in some eastern European States. The present publication is the outcome of this project: it is aimed at evaluating the situation in a number of countries, identifying variations in the technique, examining the status of the equipment and comparing performance in the light of the norms established by the European Commission. A number of important aspects are covered, including: - quality control of mammography equipment; - imaging

    In many countries near surface disposal is the preferred option for the comparatively large volumes of low and intermediate level wastes which arise during nuclear power plant operations, nuclear fuel reprocessing and also for the wastes arising from radionuclide applications in hospitals and research establishments. Near surface disposal is also widely practised in the case of hazardous wastes from chemical industries. It is obviously necessary to show that waste disposal methods are safe and that both man and the environment will be adequately protected. Following a previous related Co-ordinated Research Programme (CRP) on ''Migration and Biological Transfer of Radionuclides from Shallow Land Burial'' during 1985 to 1989 (IAEA-TECDOC-579, Vienna, 1990), the issue of reliability of safety assessments was identified as an important topic for further support and development. A new CRP was formulated with the acronym NSARS (Near Surface Radioactive Waste Disposal Safety Assessment Reliability Study). This technical document is the first report of from the CRP and contains the intercomparison of results of the first test exercise (Test Case 1) on modelling of potential radiation exposures as a result of near surface disposal. Test Case 1 is based on entirely hypothetical data and includes consideration of exposures due to leaching and as a result of human intrusion into the site. Refs, figs and tabs

    The Co-ordinated research programme on the benchmark study for the seismic analysis and testing of WWER-type nuclear power plants was initiated subsequent to the request from representatives of Member States. The conclusions adopted at the Technical Committee Meeting on Seismic Issues related to existing nuclear power plants held in Tokyo in 1991 called for the harmonization of methods and criteria used in Member States in issues related to seismic safety. The Consulltants' Meeting which followed resulted in producing a working document for CRP. It was decided that a benchmark study is the most effective way to achieve the principal objective. Two types of WWER reactors (WWER-440/213 and WWER-1000) were selected as prototypes for the benchmark exercise to be tested on a full scale using explosions and/or vibration generators. The two prototypes are Kozloduy Units 5/6 for WWER-1000 and Paks for WWER-440/213 nuclear power plants.

    1996-01-01

    Following the Chernobyl accident and on the recommendation of the International Nuclear Safety Advisory Group (INSAG) in its Summary Report on the Post-Accident Review Meeting on the Chernobyl Accident, the IAEA established a Co-ordinated Research Programme on ''The Validation of Models for the Transfer of Radionuclides in Terrestrial, Urban and Aquatic Environments and the Acquisition of Data for that Purpose''. The programme seeks to use the information on the environmental behaviour of radionuclides which became available as a result of the measurement programmes instituted in the countries of the former USSR and in many European countries after April 1986 for the purpose of testing the reliability of assessment models. Such models find application in assessing the radiological impact of all parts of the nuclear fuel cycle. They are used at the planning and design stage to predict the radiological impact of planned nuclear facilities, in assessing the possible consequences of accidents involving releases of radioactive material to the environment and in establishing criteria for the implementation of countermeasures. In the operational phase they are used together with the results of environmental monitoring to demonstrate compliance with regulatory requirements regarding release limitation. Refs, figs and tabs

  13. Quantification of tannins in tree foliage. A laboratory manual for the FAO/IAEA co-ordinated research project on 'Use of nuclear and related techniques to develop simple tannin assays for predicting and improving the safety and efficiency of feeding ruminants on tanniniferous tree foliage'

    International Nuclear Information System (INIS)

    2000-01-01

    Tanniniferous trees and shrubs are of importance in animal production because they can provide significant protein supplements, but unfortunately the amounts of tannins that they contain vary widely and largely unpredictably, and their effects on animals range from beneficial to toxicity and death. The toxic or antinutritional effects tend to occur in times of stress when a very large proportion of the diet is tanniniferous. With a better understanding of tannin properties and proper management, they could become an invaluable source of protein for strategic supplementation. As the demand for food rises, tanniniferous plants must play an increasingly important part in the diet of animals, in particular for ruminants in smallholder subsistence farming in developing countries. It is therefore critical that techniques be developed to measure and manage the anti-nutritional components that they contain. Keeping the above in mind, a Joint FAO/IAEA Co-ordinated Research Project (CRP) on 'Use of Nuclear and Related Techniques to Develop Simple Tannin Assays for Predicting and Improving the Safety and Efficiency of Feeding Ruminants on Tanniniferous Tree Foliage' has been initiated. In order to provide sound basis for this CRP, an FAO/IAEA Consultants Meeting was held in August 1997 in Vienna, at which the tanniniferous plants to be studied, the analytical methods, the test animals and the animal response evaluation techniques were defined. This publication contains methodologies for the analysis of tannins using chemical-, protein precipitation/binding- and bio-assays recommended by the consultants

The two prototypes are Kozloduy Units 5/6 for WWER-1000 and Paks for WWER-440/213 nuclear power plants. This volume of Working material contains the report experience database for Romanian facilities contingent to the three Vrancea earthquakes.

    Following the Chernobyl accident and on the recommendation of the International Nuclear Safety Advisory Group (INSAG) in its Summary Report on the Post-Accident Review Meeting on the Chernobyl Accident (Safety Series No. 75-INSAG-1, IAEA, Vienna, 1986), the IAEA established a Co-ordinated Research Programme on ''The Validation of Models for the Transfer of Radionuclides in Terrestrial, Urban and Aquatic Environments and the Acquisition of Data for that Purpose''. The programme used the information on the environmental behaviour of radionuclides which became available as a result of the measurement programmes instituted in countries of the former Soviet Union and in many European countries after April 1986 for the purpose of testing the reliability of assessment models. Such models find application in assessing the radiological impact of all parts of the nuclear fuel cycle. They are used in the planning and design stage to predict the radiological impact of nuclear facilities and in assessing the possible consequences of accidents involving releases of radioactive material to the environment and in establishing criteria for the implementation of countermeasures. In the operational phase, they are used together with the results of environmental monitoring to demonstrate compliance with regulatory requirements concerned with radiation dose limitation.

    An IAEA Co-ordinated Research Project was designed to validate the data and procedures included in the International Code of Practice Technical Reports Series (TRS) No. 381, ''The Use of Plane Parallel Ionization Chambers in High Energy Electron and Photon Beams''. This work reviews and analyses the procedures used and the data obtained by the participants of the project. The analysis shows that applying TRS-381 generally produces reliable results. The determination of absorbed dose to water using the electron method in reference conditions is within the stated uncertainties (2.9%). Comparisons have shown TRS-381 is consistent with the AAPM TG-39 protocol within 1% for measurements made in water. Based on the analysis, recommendations are given with respect to: (i) the use of plane parallel ionization chambers of the Markus type, (ii) the values for the fluence correction factor for cylindrical chambers, (iii) the value of the wall correction factor for the Roos chamber in 60 Co beams, and (iv) the use of plastic phantoms and the values of the fluence correction factors.

    A modelling approach was used to predict doses from a large area deposition of 137 Cs over southern and central Finland. The assumed deposition profile and quantity were both similar to those resulting from the Chernobyl accident. In the study, doses via terrestrial and aquatic environments have been analyzed. Additionally, the intermediate results of the study, such as concentrations in various foodstuffs and the resulting body burdents, were presented. The contributions of ingestion, inhalation and external doses to the total dose were estimated in the study. The considered deposition scenario formed a modelling exercise in the IAEA coordinated research programme on Validation of Environmental Model Predictions, the VAMP project. (21 refs.)

    Hepatocellular carcinoma is a very common neoplastic disease in countries where hepatitis viruses B and/or C are prevalent. Small hepatocellular carcinoma lesions detected by ultrasonography at an early stage are often hyperechoic because they are composed of well-differentiated cancer cells that are rich in triglyceride droplets. The triglyceride content of hepatocytes depends in part on the rate of lipogenesis. Key lipogenic enzymes, such as fatty acid synthase, are co-ordinately regulated at the transcriptional level. We therefore examined the mRNA expression of lipogenic enzymes in human hepatocellular carcinoma samples from 10 patients who had undergone surgical resection. All of the samples exhibited marked elevation of expression of mRNA for lipogenic enzymes, such as fatty acid synthase, acetyl-CoA carboxylase and ATP citrate lyase, compared with surrounding non-cancerous liver tissue. In contrast, the changes in mRNA expression of SREBP-1, a transcription factor that regulates a battery of lipogenic enzymes, did not show a consistent trend. In some cases where SREBP-1 was elevated, the main contributing isoform was SREBP-1c rather than SREBP-1a. Thus, lipogenic enzymes are markedly induced in hepatocellular carcinomas, and in some cases SREBP-1c is involved in this activation.

  6. How protein kinases co-ordinate mitosis in animal cells.

    2011-04-01

    Mitosis is associated with profound changes in cell physiology and a spectacular surge in protein phosphorylation. To accomplish these, a remarkably large portion of the kinome is involved in the process. In the present review, we will focus on classic mitotic kinases, such as cyclin-dependent kinases, Polo-like kinases and Aurora kinases, as well as more recently characterized players such as NIMA (never in mitosis in Aspergillus nidulans)-related kinases, Greatwall and Haspin. Together, these kinases co-ordinate the proper timing and fidelity of processes including centrosomal functions, spindle assembly and microtubule-kinetochore attachment, as well as sister chromatid separation and cytokinesis. A recurrent theme of the mitotic kinase network is the prevalence of elaborated feedback loops that ensure bistable conditions. Sequential phosphorylation and priming phosphorylation on substrates are also frequently employed. Another important concept is the role of scaffolds, such as centrosomes for protein kinases during mitosis. Elucidating the entire repertoire of mitotic kinases, their functions, regulation and interactions is critical for our understanding of normal cell growth and in diseases such as cancers.

    International Nuclear Information System (INIS)

    1981-05-01

    The importance of soil and water quality to agriculture and fisheries is self-evident. Soil and water ecosystems have a certain capacity to accept and degrade agrochemical residues. It is generally the microflora which determines this capacity. The residues can affect critical microbial processes such as heterotrophic activity, algal primary production, nitrification, and nitrogen fixation. Many methods have been developed to measure the fate and effects of these chemicals in the systems. Isotopic labelling is an essential tool in this measuring. Tracers are used not only to estimate the fate and conversion of the chemicals but also to measure by labelled substrate techniques their impact on the biota. The present document illustrates these different aspects. Pew measuring techniques have, however, found general acceptance. The great variety in methods hampers obtaining comparable data. The report stresses the need to seek more uniformity in methodology for estimating agrochemical residue - biota interactions in soil and aquatic ecosystems.This is a progress report containing short communications or abstracts of the papers presented at the second meeting of the Joint FAO/IAEA Coordinated research programmes on agrochemical residue - biota interactions in soil and aquatic ecosystems which was held 23-27 October 1978 in Burnaby, B.C., Canada.

    International Nuclear Information System (INIS)

    2001-01-01

    The aim of the Co-ordinated Research Programme ''Development of a Quality Assurance Programme for Radiation Therapy Dosimetry in Developing Countries'' (E2-40-07) is to establish national Quality Assurance (QA) networks for external quality audits for radiotherapy hospitals in developing countries. This is done by setting-up national External Audit Groups (EAG) with laboratory backup for operating TLD audits for radiotherapy dosimetry. The CRP offers a standardized methodology, the same for all participating countries, provides guidelines and gives technical support to the national EAG activities. In 1995-1998, the national EAGs were established in Algeria, Argentina, China, Czech Republic, India, Israel and Malaysia. At present five countries have joined the project: Colombia, Cuba, Philippines, Poland and Viet Nam. The current status of the development of methodology and procedures for QA audits in the participating countries was presented and discussed at length. Each participant has submitted the status report regarding the TLD system, measuring procedures, structure of the national EAG and relations with other relevant national organizations or bodies. The new participants are in the process of adapting the procedures developed by the IAEA and revised by the previous group in this CRP. The participants have received information on state of the art of the quality audit networks in Europe presented by Prof. Dutreix. Further discussions followed the presentations of the results of testing of the EAG measuring systems and operational procedures for audits. Special emphasis was given to issues related to legislation and national regulations in the different countries and confidentiality in reporting the audit results. Procedural problems related to endorsement of the EAGs by the relevant national bodies were noted. The composition of the national EAGs was discussed and optimal structures for the individual countries recommended. The contents of the QA manuals for

  11. Anatomical localization of electrophysiological recording sites by co-ordinate transformation.

    Science.gov (United States)

    Sinex, D G

    1997-07-18

    A method for estimating the anatomical locations of the units recorded in electrophysiological mapping experiments is described. A total of three locations must be marked by dye injections or electrolytic lesions and identified in tissue sections. From those locations, equations are derived to translate, scale, and rotate the three-dimensional co-ordinates of the recording sites, so that they are correct for a second, three-dimensional co-ordinate system based on the anatomy of the mapped structure. There is no limit to the number of recording sites that can be localized. This differs from methods that require a dye injection or lesion to be made at the exact location at which a particular unit was recorded. The accuracy of the transformed co-ordinates is limited by the accuracy with which the co-ordinates can be measured: in test measurements and in the experiments for which this algorithm was developed, the computed co-ordinates were typically accurate to within 100 microns or less.

    Research indicates the development of motor co-ordination (MC) may be an important contributing factor to positive or negative weight trajectories across childhood. To analyse cross-sectional associations between MC and weight status in children (boys n = 3344 - girls n = 3281), aged 6-11 years and assess overweight/obese risk across different ages. Body mass index (BMI) was calculated [body mass (kg)/height (m(2))]. MC was evaluated using the Körperkoordination Test für Kinder (KTK) and a motor quotient (MQ) was calculated. MQ distribution data were split into tertiles. The effect of age, sex and MQ tertiles on BMI and MC was tested with a factorial anova. A logistic regression also was performed to calculate odd ratios (OR) for being overweight/obese at each age. Children with higher MQ demonstrated lower BMI levels (F(2,6224) = 222.09; P < 0.001). Differences in BMI among MQ tertiles became larger across age (F(10,6224) = 4.53; P < 0.001). The OR of being overweight/obese in both sexes within the lowest MQ tertile increased in each age group from 6 to 11 years. Specifically, OR increased from 2.26 to 27.77 and from 1.87 to 6.81 in boys and girls respectively. Children with low levels of MC have a higher risk of being overweight/obese and this risk increases with age. © 2013 John Wiley & Sons Ltd.

    Pappas has suggested that R 4 co-ordinates can be connected with those in the R 6 by taking t'sub(x)=t'sub(y)=t'sub(z)=t'. Such connection is here obtained by introducing the scaling of space-time co-ordinates xsub(i), tsub(i) in all the frames by the corresponding factor c/c'sub(i) and have shown that taking of t'sub(x)=t'sub(y)=t'sub(z)=t' for this purpose is not necessary. The scaling factors get ignored after the connection

    A non-intrusive method is described which can be used to determine the forms of oral structures. It is based on the digitising of standard replicas with a co-ordinate-measuring machine. Supporting software permits a mathematical model of the surface to be reconstructed and visualised from captured three-dimensional co-ordinates. A series of surface data sets can be superposed into a common reference frame without the use of extrinsic markers, allowing changes in the shapes of oral structures to be quantified accurately over an extended period of time. The system has found numerous applications.

    1999-12-01

    The task of Work Package 1 (WP 1) of the EC Thematic Network 'The analysis of thorium and its isotopes in workplace materials' was to prepare an 'Inventory of current research activities in participating member states concerning thorium analysis in the workplace and environment'. The specific objective of WP 1 was 'to identify common research areas and co-ordinate activity for better management of resources'. This was to be achieved by carrying out a survey of network and national laboratories to establish the extent of current and proposed research activity in the field, evaluation of survey by network members, and production of a report containing results and conclusions. A preliminary literature review revealed that the majority of thorium analysis is carried out by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or a radiochemical technique, alpha counting and neutron activation being the most popular. In many instances there is a preconcentration or separation step, which usually involves an ion exchange column to isolate the thorium and remove the majority of the matrix. Papers concerned with the application of ICP-MS were found to feature prominently amongst recent publications, which is not surprising, as the technique is fairly newly established. Thorium was most commonly measured in geological matrixes, including soil and ores. On the basis of the results of the literature review and survey of research activity, the Network identified two key areas of priority for further research: sample preparation methods for thorium analysis; and traceable standards and certified reference materials for thorium analysis. The Network considered how best to distribute the results to interested parties to facilitate links between laboratories with common research areas, and decided that: at this stage, the findings should simply be published in the form of this interim report, which is freely available to all interested parties; the Network should continue to

    2016-01-01

    The National Health Service in Scotland published a best practice framework to support occupational therapists and physiotherapists to deliver effective services for children with developmental co-ordination disorder (DCD); however, adherence is variable. To highlight areas for development, this study compared the care pathway within a paediatric DCD service against the NHS Scotland framework. A partnership of researchers and clinicians based in the United Kingdom conducted a qualitative study with 37 participants (N = 13 interview participants, N = 24 workshop participants). In-depth interviews and/or workshops were used to map the DCD service against the NHS framework. Identified gaps were aligned with four key stages of the care pathway. Qualitative analysis software was used to analyse the data. Core principles to guide future development were identified for each phase of the pathway. These core principles related to the NHS framework and focused on issues such as involving the family, defining clear pathways and enhancing children's participation. Participants identified potential strategies for service improvement such as developing community-based interventions and information provision. Challenges when providing services for children with DCD include confusing service pathways and poor partnership working. It is, therefore, important that clinicians utilise collaborative working strategies that support children's participation. There are numerous challenges related to the implementation of best practice principles into the provision of therapy services for children with developmental coordination disorder (DCD). It is important that AHPs seek ways of engaging parents and educational professionals at all stages of the care pathway in order to ensure optimum service provision for the child. Addressing participation is an important aspect and community-based strategies may be particularly beneficial, both as a preventative activity and as an

  7. Identification of a cis-regulatory element by transient analysis of co-ordinately regulated genes

    Directory of Open Access Journals (Sweden)

    Allan Andrew C

    2008-07-01

    Full Text Available Abstract Background Transcription factors (TFs co-ordinately regulate target genes that are dispersed throughout the genome. This co-ordinate regulation is achieved, in part, through the interaction of transcription factors with conserved cis-regulatory motifs that are in close proximity to the target genes. While much is known about the families of transcription factors that regulate gene expression in plants, there are few well characterised cis-regulatory motifs. In Arabidopsis, over-expression of the MYB transcription factor PAP1 (PRODUCTION OF ANTHOCYANIN PIGMENT 1 leads to transgenic plants with elevated anthocyanin levels due to the co-ordinated up-regulation of genes in the anthocyanin biosynthetic pathway. In addition to the anthocyanin biosynthetic genes, there are a number of un-associated genes that also change in expression level. This may be a direct or indirect consequence of the over-expression of PAP1. Results Oligo array analysis of PAP1 over-expression Arabidopsis plants identified genes co-ordinately up-regulated in response to the elevated expression of this transcription factor. Transient assays on the promoter regions of 33 of these up-regulated genes identified eight promoter fragments that were transactivated by PAP1. Bioinformatic analysis on these promoters revealed a common cis-regulatory motif that we showed is required for PAP1 dependent transactivation. Conclusion Co-ordinated gene regulation by individual transcription factors is a complex collection of both direct and indirect effects. Transient transactivation assays provide a rapid method to identify direct target genes from indirect target genes. Bioinformatic analysis of the promoters of these direct target genes is able to locate motifs that are common to this sub-set of promoters, which is impossible to identify with the larger set of direct and indirect target genes. While this type of analysis does not prove a direct interaction between protein and DNA

  9. Co-ordinating innate and adaptive immunity to viral infection: mobility is the key

    DEFF Research Database (Denmark)

    Wern, Jeanette Erbo; Thomsen, Allan Randrup

    2009-01-01

    The host counters a viral infection through a complex response made up of components belonging to both the innate and the adaptive immune system. In this report, we review the mechanisms underlying this response, how it is induced and how it is co-ordinated. As cell-cell communication represents...... the very essence of immune system physiology, a key to a rapid, efficient and optimally regulated immune response is the ability of the involved cells to rapidly shift between a stationary and a mobile state, combined with stringent regulation of cell migration during the mobile state. Through the co......-ordinated recruitment of different cell types intended to work in concert, cellular co-operation is optimized particularly under conditions that may involve rare cells. Consequently, a major focus is placed on presenting an overview of the co-operative events and the associated cell migration, which is essential...

  10. Co-ordinated voltage control of DFIG wind turbines in uninterrupted operation during grid faults

    DEFF Research Database (Denmark)

    Hansen, Anca Daniela; Michalke, G.; Sørensen, Poul Ejnar

    2007-01-01

    Emphasis in this article is on the design of a co-ordinated voltage control strategy for doubly fed induction generator (DFIG) wind turbines that enhances their capability to provide grid support during grid faults. In contrast to its very good performance in normal operation, the DFIG wind turbine...... concept is quite sensitive to grid faults and requires special power converter protection. The fault ride-through and grid support capabilities of the DFIG address therefore primarily the design of DFIG wind turbine control with special focus on power converter protection and voltage control issues....... A voltage control strategy is designed and implemented in this article, based on the idea that both converters of the DFIG (i.e. rotor-side converter and grid-side converter) participate in the grid voltage control in a co-ordinated manner. By default the grid voltage is controlled by the rotor...

    It has been just over a decade since we published a paper outlining a new approach to thematic analysis (TA) entitled Using thematic analysis in psychology (Braun & Clarke, 2006). Our approach to TA has become widely used both in and beyond psychology, and particularly in applied research areas, including counselling and psychotherapy. Although TA as a distinct analytic method has increased in popularity over the last decade, we continue to see evidence of confusion about TA – what it is, wha...

    Original methodology for the study of three-dimensional biomechanics of the knee is presented in the paper. Defining the geometry of the rigid body in the body-fixed reference frame and the orientation of the body-fixed reference frame in the global co-ordinate system are the theoretic basis. The data in the form of co-ordinates of the Cartesian frame are gathered by the co-ordinate measuring machine and analysed by specially computer program. The theory and a practical example of the study of the three-dimensional biomechanics of the knee are presented. Various possibilities of the use of the methodology are discussed.

  18. Importance of intersectoral co-ordination in the control of communicable diseases, with special reference to plague in Tanzania.

    Science.gov (United States)

    Kilonzo, B S

    1994-07-01

    Human health, agriculture, including livestock, energy, education, wildlife, construction, forestry and trade sectors are inter-related and their co-ordination is an important pre-requisite for successful control of most communicable diseases including plague. Similar linkage between research, policy, training and extension activities in each sector are essential for any successful control strategy. Inadequate agricultural produce, inaccessibility of people to the available food and ignorance on proper preparation and usage of available food materials are responsible for malnutrition, and malnourished people are very vulnerable to disease. Irrigation schemes facilitate breeding of various disease vectors and transmission of some communicable diseases. Forests are ecologically favourable for some disease vectors and reservoirs for tsetse flies and rodents, while deforestation leads to soil erosion, lack of rainfall and consequently reduced productivity in agriculture which may result in poor nutrition of the population. Wildlife and livestock serve as reservoirs and/or carriers of various zoonoses including plague, trypanosomiasis and rabies. Lack of proper co-ordination of these sectors in communicable disease control programmes can result in serious and undesirable consequences. Indiscriminate killing of rodents in order to minimize food damage by these vermin forces their flea ectoparasites to seek alternative hosts, including man, a development which may result in transmission of plague from rodents to man. Similarly, avoidance of proper quarantine during plague epidemics, an undertaking which is usually aimed at maintaining economic and social links with places outside the affected focus, can result in the disease becoming widespread and consequently make any control strategies more difficult and expensive.(ABSTRACT TRUNCATED AT 250 WORDS)

    Co-ordinated approaches to community-based care are a central component of current and proposed efforts to help vulnerable older adults obtain needed services and supports and reduce unnecessary use of health care resources. This study examines ElderHelp Concierge Club, an integrated community-based care model that includes comprehensive personal and environmental assessment, multilevel care co-ordination, a mix of professional and volunteer service providers, and a capitated, income-adjusted fee model. Evaluation includes a retrospective study (n = 96) of service use and perceived program impact, and a prospective study (n = 21) of changes in participant physical and social well-being and health services utilization. Over the period of this study, participants showed greater mobility, greater ability to meet household needs, greater access to health care, reduced social isolation, reduced home hazards, fewer falls, and greater perceived ability to obtain assistance needed to age in place. This study provides preliminary evidence that an integrated multilevel care co-ordination approach may be an effective and efficient model for serving vulnerable community-based elders, especially low and moderate-income elders who otherwise could not afford the cost of care. The findings suggest the need for multisite controlled studies to more rigorously evaluate program impacts and the optimal mix of various program components. © The Author 2014.

  1. Spatial and thematic distribution of research on cyanotoxins.

    Science.gov (United States)

    Merel, Sylvain; Villarín, María C; Chung, Khrystyne; Snyder, Shane

    2013-12-15

    Cyanobacteria in surface water are well known for their ability to form toxic blooms responsible for animal mortality and human poisoning. Accompanying major progress in science and technology, the state of knowledge of cyanotoxins has dramatically increased over the last two decades. The bibliometric approach applied in this study shows the evolution of research and identifies major gaps to be filled by future work. Although the publication rate has gradually increased from one hundred to three hundred articles per year since the 1990s, half of the literature available focuses on microcystins and another quarter on saxitoxins. Other cyanotoxins such as beta-N-methylamino-l-alanine or cylindrospermopsin remain vastly disregarded. Moreover, most of the publications deal with toxicity and ecology while other research areas, such as environmental and public health, require additional investigation. The analysis of the literature highlights the main journals for the communication of knowledge on cyanotoxins but also reveals that 90% of the research is originated from only ten countries. These countries are also those with the highest H-index and average number of citation per article. Nonetheless, the ranking of these countries is significantly altered when the amount of publications is normalized based on the population, the number of universities, the national gross domestic product or the government revenue. However, the lower amount of publications from Eastern Europe, Africa and South America could also reflect the lack of monitoring campaigns in these regions. This lack could potentially lead to the underestimation of the prevalence of toxic cyanobacterial blooms and the diversity of toxins worldwide. Copyright © 2013 Elsevier Ltd. All rights reserved.

  2. Irradiation of fuels and materials in the Jules Horowitz reactor: The 6th European Union JHR co-ordination action (JHR-CA)

    2005-01-01

    The Fermine thematic network in the 5th FP pointed out the need for a new MTR facility in Europe to answer the continuous need of irradiation capabilities for fission power reactors and fusion facilities and to face the ageing of present MTRs. The Jules Horowitz Reactor (JHR) Project in Cadarache copes with this context, as an international service-oriented user-facility. In the field of nuclear fuels and materials irradiation experiments, a 6th FP co-ordination action, called JHR-CA, has started at the beginning of 2004 for 2 years. The main objective is to network existing expertise on development of a new generation of experimental devices, through definition of conceptual designs, instrumentation and related in-reactor services. This paper presents the outline of the JHR project, the organization of the JHR-CA programme, and a choice of irradiation device conceptual design results. (author)

  3. Ethical aspects in tissue research: thematic analysis of ethical statements to the research ethics committee

    Science.gov (United States)

    2012-01-01

    Background Many studies have been published about ethics committees and the clarifications requested about the submitted applications. In Finland, ethics committees require a separate statement on ethical aspects of the research in applications to the ethics committee. However, little is known about how researchers consider the ethical aspects of their own studies. Methods The data were collected from all the applications received by the official regional ethics committee in the Hospital District of Northern Savo during 2004–2009 (n = 688). These included a total of 56 studies involving research on tissue other than blood. The statements by the researchers about the ethics about their own research in these applications were analyzed by thematic content analysis under the following themes: recruitment, informed consent, risks and benefits, confidentiality and societal meaning. Results The researchers tended to describe recruitment and informed consent process very briefly. Usually these descriptions simply stated who the recruiter was and that written consent would be required. There was little information provided on the recruitment situation and on how the study recruiters would be informed. Although most of the studies were clinical, the possibility was hardly ever discussed that patients could fail to distinguish between care and research. Conclusion The written guidelines, available on the webpages of the ethics committee, do not seem to be enough to help researchers achieve this goal. In addition to detailed guidelines for researchers, investigators need to be taught to appreciate the ethical aspects in their own studies. PMID:22873761

    The Plant Life Assessment Network (PLAN) is a Brite Euram Type II Thematic Network, initiated by the European Commission to facilitate structured co-operation between all cost shared action projects already funded by the Commission which fall under this common technical theme. The projects involved address a multiplicity of problems associated with plant life assessment and are drawn from Brite-Euram, Standards, Measurement and Testing, Nuclear Fission Safety and Esprit EC programmes. The main aim of the Network is to initiate, maintain and monitor a fruitful co-operation process between completed, ongoing and future EC R and D projects, thereby promoting improved cross fertilization and enhanced industrial exploitation of R and D results. As the project is in its infancy, this presentation covers the background to the initiative in some detail. In particular two key aspects are highlighted, namely, the requirement of the EC to launch such a network in the area of plant life assessment including its evolution from two small Thematic Research Actions and, secondly, the mechanism for structuring the Network in an ordered and proven way along the lines of the EC/JRC European Networks, PISC, NESC, AMES, ENIQ, ENAIS and EPERC. The operating and financial structure of the Network is detailed with reference made to the role of the executive Steering Committee, The Network Project Leader and the Network Financial Co-ordinator.

    McEvoy, Phil; Escott, Diane; Bee, Penny

    2011-01-01

    This study is based on a formative evaluation of a case management service for high-intensity service users in Northern England. The evaluation had three main purposes: (i) to assess the quality of the organisational infrastructure; (ii) to obtain a better understanding of the key influences that played a role in shaping the development of the service; and (iii) to identify potential changes in practice that may help to improve the quality of service provision. The evaluation was informed by Gittell's relational co-ordination theory, which focuses upon cross-boundary working practices that facilitate task integration. The Assessment of Chronic Illness Care Survey was used to assess the organisational infrastructure and qualitative interviews with front line staff were conducted to explore the key influences that shaped the development of the service. A high level of strategic commitment and political support for integrated working was identified. However, the quality of care co-ordination was variable. The most prominent operational factor that appeared to influence the scope and quality of care co-ordination was the pattern of interaction between the case managers and their co-workers. The co-ordination of patient care was much more effective in integrated co-ordination networks. Key features included clearly defined, task focussed, relational workspaces with interactive forums where case managers could engage with co-workers in discussions about the management of interdependent care activities. In dispersed co-ordination networks with fewer relational workspaces, the case managers struggled to work as effectively. The evaluation concluded that the creation of flexible and efficient task focused relational workspaces that are systemically managed and adequately resourced could help to improve the quality of care co-ordination, particularly in dispersed networks. © 2010 Blackwell Publishing Ltd.

  9. Insulation co-ordination aspects for power stations with generator circuit-breakers

    Sanders, M.; Koeppl, G.; Kreuzer, J.

    1995-01-01

    The generator circuit-breaker (gen. c.b.) located between the generator and the step-up transformer, is now being applied world-wide. It has become a recognized electrical component of power stations which is largely due to economical advantages and increased power station availability. Technical protection considerations for power stations have always been the reason for discussion and the object of improvement. With the use of a gen. c.b., some points of view need to be considered anew. Not only the protection system in case of fault conditions will be influenced, but also the insulation co-ordination philosophy. Below the results of some calculations concerning expected overvoltages are presented. These calculations are based on a transformer rated 264/15.5kV, 220 MVA. But the results are transferable to other power plants. Some measurements carried out on a transformer of the same rating complement the calculations. The findings may contribute to an improvement in insulation co-ordination and protection of the electrical system generator--step-up transformer

    1995-12-31

    A modern approach to relay co-ordination that takes advantage of the improved performance of modern protective relays and circuits was proposed. The proposed method dealt with a mixture of new and old equipment and was most useful when implemented using common spreadsheet software. The suggested approach justified reduced time margins for relay co-ordination in many difficult applications. Other established approaches were reviewed. A discussion of fixed and variable time margin allowances was presented. The formulation of an equation to determine the required upstream relay operating time was explained, with sample calculations. Relay performance standards and modern protective equipment were discussed. It was concluded that modern relays and circuit breakers are much more advanced than designs of the recent past. The method described allowed significant reductions in margins which enabled modern relays to operate faster. While calculations for the procedures were said to be tedious to perform by hand, they can be easily done with spreadsheet software. 10 refs., 4 figs.

  11. Co-ordinate regulation of genes involved in storage lipid mobilization in Arabidopsis thaliana.

    2001-05-01

    Molecular genetic approaches in the model plant Arabidopsis thaliana (Col0) are shedding new light on the role and control of the pathways associated with the mobilization of lipid reserves during oilseed germination and post-germinative growth. Numerous independent studies have reported on the expression of individual genes encoding enzymes from the three major pathways: beta-oxidation, the glyoxylate cycle and gluconeogenesis. However, a single comprehensive study of representative genes and enzymes from the different pathways in a single plant species has not been done. Here we present results from Arabidopsis that demonstrate the co-ordinate regulation of gene expression and enzyme activities for the acyl-CoA oxidase- and 3-ketoacyl-CoA thiolase-mediated steps of beta-oxidation, the isocitrate lyase and malate synthase steps of the glyoxylate cycle and the phosphoenolpyruvate carboxykinase step of gluconeogenesis. The mRNA abundance and enzyme activities increase to a peak at stage 2, 48 h after the onset of seed germination, and decline thereafter either to undetectable levels (for malate synthase and isocitrate lyase) or low basal levels (for the genes of beta-oxidation and gluconeogenesis). The co-ordinate induction of all these genes at the onset of germination raises the possibility that a global regulatory mechanism operates to induce the expression of genes associated with the mobilization of storage reserves during the heterotrophic growth period.

  12. Efficient nonlinear registration of 3D images using high order co-ordinate transfer functions.

    Science.gov (United States)

    Barber, D C

    1999-01-01

    There is an increasing interest in image registration for a variety of medical imaging applications. Image registration is achieved through the use of a co-ordinate transfer function (CTF) which maps voxels in one image to voxels in the other image, including in the general case changes in mapped voxel intensity. If images of the same subject are to be registered the co-ordinate transfer function needs to implement a spatial transformation consisting of a displacement and a rigid rotation. In order to achieve registration a common approach is to choose a suitable quality-of-registration measure and devise a method for the efficient generation of the parameters of the CTF which minimize this measure. For registration of images from different subjects more complex transforms are required. In general function minimization is too slow to allow the use of CTFs with more than a small number of parameters. However, provided the images are from the same modality and the CTF can be expanded in terms of an appropriate set of basis functions this paper will show how relatively complex CTFs can be used for registration. The use of increasingly complex CTFs to minimize the within group standard deviation of a set of normal single photon emission tomography brain images is used to demonstrate the improved registration of images from different subjects using CTFs of increasing complexity.

  13. Copying you copying me: interpersonal motor co-ordination influences automatic imitation.

    Directory of Open Access Journals (Sweden)

    Daniel Joel Shaw

    Full Text Available Moving in a co-ordinated fashion with another individual changes our behaviour towards them; we tend to like them more, find them more attractive, and are more willing to co-operate with them. It is generally assumed that this effect on behaviour results from alterations in representations of self and others. Specifically, through neurophysiological perception-action matching mechanisms, interpersonal motor co-ordination (IMC is believed to forge a neural coupling between actor and observer, which serves to blur boundaries in conceptual self-other representations and causes positive views of the self to be projected onto others. An investigation into this potential neural mechanism is lacking, however. Moreover, the specific components of IMC that might influence this mechanism have not yet been specified. In the present study we exploited a robust behavioural phenomenon--automatic imitation--to assess the degree to which IMC influences neural action observation-execution matching mechanisms. This revealed that automatic imitation is reduced when the actions of another individual are perceived to be synchronised in time, but are spatially incongruent, with our own. We interpret our findings as evidence that IMC does indeed exert an effect on neural perception-action matching mechanisms, but this serves to promote better self-other distinction. Our findings demonstrate that further investigation is required to understand the complex relationship between neural perception-action coupling, conceptual self-other representations, and social behaviour.

  14. Methods for the thematic synthesis of qualitative research in systematic reviews

    2008-07-01

    Full Text Available Abstract Background There is a growing recognition of the value of synthesising qualitative research in the evidence base in order to facilitate effective and appropriate health care. In response to this, methods for undertaking these syntheses are currently being developed. Thematic analysis is a method that is often used to analyse data in primary qualitative research. This paper reports on the use of this type of analysis in systematic reviews to bring together and integrate the findings of multiple qualitative studies. Methods We describe thematic synthesis, outline several steps for its conduct and illustrate the process and outcome of this approach using a completed review of health promotion research. Thematic synthesis has three stages: the coding of text 'line-by-line'; the development of 'descriptive themes'; and the generation of 'analytical themes'. While the development of descriptive themes remains 'close' to the primary studies, the analytical themes represent a stage of interpretation whereby the reviewers 'go beyond' the primary studies and generate new interpretive constructs, explanations or hypotheses. The use of computer software can facilitate this method of synthesis; detailed guidance is given on how this can be achieved. Results We used thematic synthesis to combine the studies of children's views and identified key themes to explore in the intervention studies. Most interventions were based in school and often combined learning about health benefits with 'hands-on' experience. The studies of children's views suggested that fruit and vegetables should be treated in different ways, and that messages should not focus on health warnings. Interventions that were in line with these suggestions tended to be more effective. Thematic synthesis enabled us to stay 'close' to the results of the primary studies, synthesising them in a transparent way, and facilitating the explicit production of new concepts and hypotheses

    Tc(S 2 CNEt 2 ) 3 CO has been prepared by the reduction of NH 4 TcO 4 with formamidinesulphinic acid in the presence of NaS 2 CNEt 2 . It is suggested that the co-ordinated carbon monoxide is formed after co-ordination of formamidinesulphinic acid, or some decomposition product, with technetium. The crystal structure of Tc(S 2 CNEt 2 ) 3 CO has been determined by single-crystal X-ray diffraction methods at 17 deg. C. Diffractometry has provided significant Bragg intensities for 2045 independent reflections and the structure has been refined by full-matrix least-squares methods to R 0.049. The compound is isostructural with the rhenium analogue and consists of discrete Tc(S 2 CNEt 2 ) 3 CO molecules, each containing a terminal linear CO group. The technetium atom has a seven co-ordinate environment which is best described as a distorted pentagonal bipyramid

  18. A co-ordinate system for reactor physics calculations in hexagonal geometry

    Burte, D.P.

    1990-01-01

    A method for generating all the geometric information concerning typical reactor physics calculations for a basically hexagonal reactor core or its sector involving any of the possible symmetries is presented. The geometrically allowed symmetries for regular hexagons are discussed. The approach is based on the choice of a suitable co-ordinate system, viz. one using three coplanar (including one redundant) axes, each at 120 0 with its cyclically preceding one. A code named KEKULE' is developed for a 2-D, finite difference, one-group diffusion analysis of a hexagonal core using the approach. It can cater to a full hexagonal core as well as to any symmetric sectorial part of it. The main feature of the code is that the input concerning geometry is a bare minimum. It is hoped that the approach presented will be useful even for the calculations for hexagonal fuel assemblies. (author)

    Shoot branching is a primary contributor to plant architecture, evolving independently in flowering plant sporophytes and moss gametophytes. Mechanistic understanding of branching is largely limited to flowering plants such as Arabidopsis, which have a recent evolutionary origin. We show that in gametophytic shoots of Physcomitrella, lateral branches arise by re-specification of epidermal cells into branch initials. A simple model co-ordinating the activity of leafy shoot tips can account for branching patterns, and three known and ancient hormonal regulators of sporophytic branching interact to generate the branching pattern- auxin, cytokinin and strigolactone. The mode of auxin transport required in branch patterning is a key divergence point from known sporophytic pathways. Although PIN-mediated basipetal auxin transport regulates branching patterns in flowering plants, this is not so in Physcomitrella, where bi-directional transport is required to generate realistic branching patterns. Experiments with callose synthesis inhibitors suggest plasmodesmal connectivity as a potential mechanism for transport.

    The development of gastro-oesophageal reflux disease (GORD) is known to be a causative risk factor in the evolution of adenocarcinoma of the oesophagus. The major component of this reflux is gastric acid. However, the impact of low pH on gene expression has not been extensively studied in oesophageal cells. This study utilizes a transcriptomic and bioinformatic approach to assess regulation of gene expression in response to low pH. In more detail, oesophageal adenocarcinoma cell lines were exposed to a range of pH environments. Affymetrix microarrays were used for gene-expression analysis and results were validated using cycle limitation and real-time RT-PCR analysis, as well as northern and western blotting. Comparative promoter transcription factor binding site (TFBS) analysis (MatInspector) of hierarchically clustered gene-expression data was employed to identify the elements which may co-ordinately regulate individual gene clusters. Initial experiments demonstrated maximal induction of EGR1 gene expression at pH 6.5. Subsequent array experimentation revealed significant induction of gene expression from such functional categories as DNA damage response (EGR1-4, ATF3) and cell-cycle control (GADD34, GADD45, p57). Changes in expression of EGR1, EGR3, ATF3, MKP-1, FOSB, CTGF and CYR61 were verified in separate experiments and in a variety of oesophageal cell lines. TFBS analysis of promoters identified transcription factors that may co-ordinately regulate gene-expression clusters, Cluster 1: Oct-1, AP4R; Cluster 2: NF-kB, EGRF; Cluster 3: IKRS, AP-1F. Low pH has the ability to induce genes and pathways which can provide an environment suitable for the progression of malignancy. Further functional analysis of the genes and clusters identified in this low pH study is likely to lead to new insights into the pathogenesis and therapeutics of GORD and oesophageal cancer.

    The present studies examined the effect of agents that induce peroxisomal and mitochondrial beta-oxidation on hepatic mitochondrial carnitine palmitoyltransferase (CPT) and peroxisomal carnitine acyltransferase [CPTs of Ramsay (1988) Biochem. J. 249, 239-245; COT of Farrell & Bieber (1983) Arch. Biochem. Biophys. 222, 123-132 and Miyazawa, Ozasa, Osumi & Hashimoto (1983) J. Biochem. 94, 529-542]. In the first studies, high fat diets containing corn oil or fish oil were used to induce peroxisomal and mitochondrial enzymes. Rats were fed one of three diets for 4 weeks: (1) low fat, with corn oil as 11% of energy (kJ); (2) high fat, with corn oil as 45% of kJ; (3) high fat, with fish oil as 45% of kJ. At the end of 4 weeks, both mitochondrial CPT and peroxisomal CPTs exhibited increases in activity, immunoreactive protein, mRNA levels and transcription rates in livers of rats fed either high-fat diet compared to the low fat diet. Riboflavin deficiency or starvation for 48 h also increased the peroxisomal CPTs mRNA. A second set of studies used the plasticizer 2-(diethylhexyl)phthalate (DEHP), 0.5% clofibrate or 1% acetylsalicylic acid (fed for 3 weeks) to alter peroxisomal and mitochondrial fatty acid oxidation. With DEHP, the mitochondrial CPT and peroxisomal CPTs activity, immunoreactive protein, mRNA levels and and transcription rate were all increased by 3-5-fold. The peroxisomal CPTs activity, immunoreactive protein, mRNA levels and transcription rate were increased 2-3-fold by clofibrate and acetylsalicylic acid, again similar to mitochondrial CPT. The results of the combined studies using both diet and drugs to cause enzyme induction suggest that the synthesis of the carnitine acyltransferases (mitochondrial CPT and peroxisomal CPTs) may be co-ordinated with each other; however, the co-ordinate regulatory factors have not yet been identified.

    To review the results of five research projects commissioned to enhance alcohol treatment among Aboriginal Australians, and to highlight arising from them. Drafts of the papers were workshopped by project representatives, final papers reviewed and results summarised. Lessons arising were identified and described. While the impact of the projects varied, they highlight the feasibility of adapting mainstream interventions in Aboriginal Australian contexts. Outcomes include greater potential to: screen for those at risk; increase community awareness; build capacity and partnerships between organisations; and co-ordinate comprehensive referral networks and service provision. Results show a small investment can produce sustainable change and positive outcomes. However, to optimise and maintain investment, cultural difference needs to be recognised in both planning and delivery of alcohol interventions; resources and funding must be responsive to and realistic about the capacities of organisations; partnerships need to be formed voluntarily based on respect, equality and trust; and practices and procedures within organisations need to be formalised. There is no simple way to reduce alcohol-related harm in Aboriginal communities. However, the papers reviewed show that with Aboriginal control, modest investment and respectful collaboration, service enhancements and improved outcomes can be achieved. Mainstream interventions need to be adapted to Aboriginal settings, not simply transferred. The lessons outlined provide important reflections for future research. © 2014 Australasian Professional Society on Alcohol and other Drugs.

    Full Text Available This study performed two phases of analysis to shed light on the performance and thematic evolution of China's quantum cryptography (QC research. First, large-scale research publication metadata derived from QC research published from 2001-2017 was used to examine the research performance of China relative to that of global peers using established quantitative and qualitative measures. Second, this study identified the thematic evolution of China's QC research using co-word cluster network analysis, a computational science mapping technique. The results from the first phase indicate that over the past 17 years, China's performance has evolved dramatically, placing it in a leading position. Among the most significant findings is the exponential rate at which all of China's performance indicators (i.e., Publication Frequency, citation score, H-index are growing. China's H-index (a normalized indicator has surpassed all other countries' over the last several years. The second phase of analysis shows how China's main research focus has shifted among several QC themes, including quantum-key-distribution, photon-optical communication, network protocols, and quantum entanglement with an emphasis on applied research. Several themes were observed across time periods (e.g., photons, quantum-key-distribution, secret-messages, quantum-optics, quantum-signatures; some themes disappeared over time (e.g., computer-networks, attack-strategies, bell-state, polarization-state, while others emerged more recently (e.g., quantum-entanglement, decoy-state, unitary-operation. Findings from the first phase of analysis provide empirical evidence that China has emerged as the global driving force in QC. Considering China is the premier driving force in global QC research, findings from the second phase of analysis provide an understanding of China's QC research themes, which can provide clarity into how QC technologies might take shape.

    We assessed reproducible definition of two standardized co-ordinate systems for intersubject analysis of brain images. The baselines in the two co-ordinate systems were a modification of the canthomeatal (mCM) line and the anterior-posterior commissural (AC-PC) line. Axial spin-echo MR images of four subjects at 1.5T were used. Operator error was computed from the replicate analyses of two operators. The mCM line was determined by the lens of the eye and the internal auditory canal, and the AC-PC line was determined by the intersection of AC and PC with the interhemispheric fissure. Reproducibility of the mCM markers (SD = 0.59 mm) did not differ significantly from that of the AC-PC line (SD = 0.68 mm). The measurement error of the angle of the baseline (delta alpha), however, was more than 7 times as large for the AC-PC line as for the mCM line. An additional error affecting the rostrocaudal rotation of the co-ordinate systems, attributable to the distance between the anatomic markers, was 2.1 and 3.6 degrees (3 mm and 5 mm slice thickness) for the mCM co-ordinate system and 8.2 and 11.0 degrees (3 mm and 5 mm slice thickness) for the AC-PC system. The AC-PC line based co-ordinate system is therefore, less reproducible than the mCM line based system. This could be improved if a combination of axial and sagittal images were used for the definition of the AC-PC line.

  11. Self-processing 2A-polyproteins--a system for co-ordinate expression of multiple proteins in transgenic plants.

    Achieving co-ordinate, high-level and stable expression of multiple transgenes in plants is currently difficult. Expression levels are notoriously variable and influenced by factors that act independently on transgenes at different genetic loci. Instability of expression due to loss, re-arrangement or silencing of transgenes may occur, and is exacerbated by increasing numbers of transgenic loci and repeated use of homologous sequences. Even linking two or more genes within a T-DNA does not necessarily result in co-ordinate expression. Linking proteins in a single open reading frame--a polyprotein--is a strategy for co-ordinate expression used by many viruses. After translation, polyproteins are processed into constituent polypeptides, usually by proteinases encoded within the polyprotein itself. However, in foot-and-mouth disease virus (FMDV), a sequence (2A) of just 16-20 amino acids appears to have the unique capability to mediate cleavage at its own C-terminus by an apparently enzyme-independent, novel type of reaction. This sequence can also mediate cleavage in a heterologous protein context in a range of eukaryotic expression systems. We have constructed a plasmid in which the 2A sequence is inserted between the reporter genes chloramphenicol acetyltransferase (CAT) and beta-glucuronidase (GUS), maintaining a single open reading frame. Here we report that expression of this construct in wheatgerm lysate and transgenic plants results in efficient cleavage of the polyprotein and co-ordinate expression of active CAT and GUS. Self-processing polyproteins using the FMDV 2A sequence could therefore provide a system for ensuring co-ordinated, stable expression of multiple introduced proteins in plant cells.

    1997-01-01

    Every year, an average of eight new civilian remote sensing satellite missions are launched. Cumulatively, over 250 such missions, each with a cost equivalent in current value to between US 100 million to US 1000 million, have been sponsored by space agencies in perhaps two dozen countries. These missions produce data and information products which are vital for informed decision making all over the world, on matters relating to natural resource exploitation, health and safety, sustainable national development, infrastructure planning, and a host of other applications. By contributing to better scientific understanding of global changes in the atmosphere, land surface, oceans and ice caps, these silently orbiting sentinels in the sky make it possible for governments and industries to make wiser environmental policy decisions and support the economic development needs of humanity. The international Committee on Earth Observation Satellites (CEOS) is the premier world body for co-ordinating and planning civilian satellite missions for Earth observation. Through its technical working groups and special task teams, it endeavours to: • maximise the international benefits from Earth observation satellites; and • harmonise practice in calibration, validation, data management and information systems for Earth observation. CEOS encompasses not only space agencies (data providers), but also the great international scientific and operational programs which rely on Earth science data from space. The user organisations affiliated with CEOS, together with the mission operators, attempt to reconcile user needs with the complex set of considerations — including national interests, cost, schedule — which affect the undertaking of space missions. Without such an internationally co-ordinated consensual approach, there is a much greater risk of waste through duplication, and of missed opportunity, or through the absence of measurements of some vital physical or biological

  13. Bonegilla Heritage Park: Contesting and Co-ordinating a Public History Site

    Alexandra Dellios

    2012-10-01

    Full Text Available Since the 1980s, efforts to publically commemorate the former migrant training and reception centre of Bonegilla, while intermittent, have increased. I am referring to: reunions and anniversaries, state and national heritage listings, the erection of museum displays, temporary and touring exhibitions, the on-site Heritage Park, and forms of popular culture. For the national audience, as well as several ethnic communities, Bonegilla now plays a role in the collective imagination of the post-war period and the migrant journey. Furthermore, the nature of Bonegilla’s public representation has evolved since the late 1980s. Bonegilla has become much more than a place of personal migrant memory, and its previous negative connotations in the public arena have been erased. This public evolution is linked to much wider processes in our national history. This article thus explores the contestation and co-ordination of collective memories—that is, multiple narratives of Bonegilla’s past, which, while in constant dialogue with each other, are framed and sanctioned by the limits of Australian multiculturalism and heritage discourses. While the earliest efforts to commemorate Bonegilla might be typified as ‘participatory’ and vernacular, they might now be described in reference to ‘retrospective commemoration’, in which Bonegilla’s public history is framed by state-sanctioned narratives and other attendant discursive frameworks.

  14. nilR is necessary for co-ordinate repression of Xenorhabdus nematophila mutualism genes.

    Science.gov (United States)

    Cowles, Charles E; Goodrich-Blair, Heidi

    2006-11-01

    The bacterial mutualist Xenorhabdus nematophila colonizes a specific region of its nematode host Steinernema carpocapsae. We previously reported the identification of a chromosomal locus encoding three X. nematophila genes of unknown function, nilA, B and C, that are each necessary for colonization. Subsequent work indicated the global regulator Lrp is a repressor of nilC: nilC transcription is elevated in an lrp mutant and Lrp interacts directly with the nilC promoter. In this manuscript, we report the identification of an additional gene, nilR, required for repression of nilC transcription. We show that nilR and lrp mutants also have elevated expression of nilA and nilB, demonstrating that nilA, B and C are co-ordinately regulated. nil gene expression is derepressed most strongly when both nilR and lrp are lacking, suggesting NilR and Lrp synergistically repress nil transcription. NilR contains a helix-turn-helix-type DNA binding domain and likely acts directly at promoters. A comparison of the wild type and nilR proteomes indicates that NilR, unlike Lrp, regulates a small number of genes. Finally, X. nematophila carrying an ectopic copy of nilR colonizes at approximately 60-fold lower levels than the control strain, suggesting that derepression of nil gene expression is necessary for nematode colonization.

    Full Text Available Physical Therapy is a profession which development and conceptual framework have been performed in the twentieth century. One of the major challenges of Physical Therapy in the twenty-first century is to identify the intellectual basis of its scientific domain. The aim of the present paper is to analyze the evolution of Physical Therapy research throughout scientific literature published in Web of Science (WoS and Scopus databases. In order to perform the analysis, WoS and Scopus bibliographic databases were used to download all records. A set of journals with overall topics in Physical Therapy discipline with the largest history in the Journal Citation Report were selected: Physiotherapy, Physical Therapy, and Australian Journal of Physiotherapy/Journal of Physiotherapy. The bibliometric tool SciMAT was employed to perform a science mapping analysis in order to detect and visualize the research themes and their evolution across three periods: 1951–1984, 1985–2000, and 2001–2013. The analysis carried out shows that Physical Therapy research field is mainly divided into nine thematic areas: Middle-Aged People, Muscle Function Alterations and Recovery, Health Education, Gait and Biomechanics, Central Nervous System, Heart Rate and Exercise, Diagnosis, Low Back Pain, and Animals. In conclusion, Physical Therapy citations and production are primarily focused on two large thematic areas, diseases that involve middle-aged population and muscle function and its alterations. Results can be used to provide a historical perspective on research conducted in this emerging field and to provide a scientific evidence-based practice model on which future studies can be built.

    The structure of the title compound has been determined by single-crystal X-ray diffraction methods from diffractometer data and refined to a final R of 0.023. The compound crystallises in space group R3c with asub(hex) = 18.447(3), csub(hex) = 19.348(3) A, Z = 6. The uranium atom is co-ordinated to one chlorine (U-Cl 2.813 A) and six oxygen atoms (mean U-O 2.26 A); the co-ordination polyhedron can be described as a distorted monocapped trigonal antiprism or as a distorted monocapped octahedron. The anionic chlorines are more than 6.22 A from the uranium atoms. The results are discussed in relation to spectral data for this and related uranium(IV) complexes.

  20. How can the co-ordinate transformation method of beam matching be extended to include separately labelled collimators?

    Morgan-Fletcher, S; McKenzie, A L

    1996-03-01

    The problem of matching radiation beams was tackled by Siddon in 1980 using co-ordinate transformations. Since then, the need to distinguish between individual collimators in prescriptions of treatment set-up, brought about by the widespread use of 3-D treatment planning systems and asymmetric fields, as well as a reversal of the rotation sense in the turntable co-ordinate system proposed by the International Electrotechnical Commission, have made it necessary to revisit this particular problem. This paper builds upon Siddon's general equations for the particular case of matching beams, and derives expressions for calculating treatment-unit settings which may be used in a computer program without the need to perform matrix manipulation. The expression treat the individual collimator jaws separately.

    2013-02-01

    Recently, several light receptors have been identified in non-phototrophic bacteria, but their physiological roles still remain rather elusive. Here we show that colonies of the saprophytic bacterium Listeria monocytogenes undergo synchronized multicellular behaviour on agar plates, in response to oscillating light/dark conditions, giving rise to alternating ring formation (opaque and translucent rings). On agar plates, bacteria from opaque rings survive increased levels of reactive oxygen species (ROS), as well as repeated cycles of light and dark, better than bacteria from translucent rings. The ring formation is strictly dependent on a blue-light receptor, Lmo0799, acting through the stress-sigma factor, σ(B) . A transposon screening identified 48 mutants unable to form rings at alternating light conditions, with several of them showing a decreased σ(B) activity/level. However, some of the tested mutants displayed a varied σ(B) activity depending on which of the two stress conditions tested (light or H(2) O(2) exposure). Intriguingly, the transcriptional regulator PrfA and the virulence factor ActA were shown to be required for ring formation by a mechanism involving activation of σ(B) . All in all, this suggests a distinct pathway for Lmo0799 that converge into a common signalling pathway for σ(B) activation. Our results show that night and day cycles co-ordinate a reversible differentiation of a L. monocytogenes colony at room temperature, by a process synchronized by a blue-light receptor and σ(B) . © 2013 Blackwell Publishing Ltd.

    Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach has been combined with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed 'top-down' role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. Copyright © 2017.

    Evidence-based practice aims to achieve better health outcomes in the community. It relies on high quality research to inform policy and practice; however research in primary health care continues to lag behind that of other medical professions. The literature suggests that research capacity building (RCB) functions across four levels; individual, team, organisation and external environment. Many RCB interventions are aimed at an individual or team level, yet evidence indicates that many barriers to RCB occur at an organisational or external environment level. This study asks senior managers from a large healthcare organisation to identify the barriers and enablers to RCB. The paper then describes strategies for building allied health (AH) research capacity at an organisational level from a senior managers' perspective. This qualitative study is part of a larger collaborative RCB project. Semi-structured in-depth interviews were conducted with nine allied health senior managers. Recorded interviews were transcribed and NVivo was used to analyse findings and emergent themes were defined. The dominant themes indicate that the organisation plays an integral role in building AH research capacity and is the critical link in creating synergy across the four levels of RCB. The organisation can achieve this by incorporating research into its core business with a whole of organisation approach including its mission, vision and strategic planning. Critical success factors include: developing a co-ordinated and multidisciplinary approach to attain critical mass of research-active AH and enhance learning and development; support from senior managers demonstrated through structures, processes and systems designed to facilitate research; forming partnerships to increase collaboration and sharing of resources and knowledge; and establishing in internal framework to promote recognition for research and career path opportunities. This study identifies four key themes: whole of

    This laboratory manual contains the methodologies used in the standardization and validation of the urine purine derivative technique for estimating microbial protein supply to the rumen. It includes descriptions of methods that involve both radioactive and stable isotopes as well as non isotopic techniques such as chemical assays, since it has been recognised that while isotopic trace techniques provide a powerful tool for nutrition research they can not and should not be used in isolation.

    In today's NHS, qualitative research is increasingly important as a method of assessing and improving quality of care. Grounded theory has developed as an analytical approach to qualitative data over the last 40 years. It is primarily an inductive process whereby theoretical insights are generated from data, in contrast to deductive research where theoretical hypotheses are tested via data collection. Grounded theory has been one of the main contributors to the acceptance of qualitative methods in a wide range of applied social sciences. The influence of grounded theory as an approach is, in part, based on its provision of an explicit framework for analysis and theory generation. Furthermore the stress upon grounding research in the reality of participants has also given it credence in healthcare research. As with all analytical approaches, grounded theory has drawbacks and limitations. It is important to have an understanding of these in order to assess the applicability of this approach to healthcare research. In this review we outline the principles of grounded theory, and focus on thematic analysis as the analytical approach used most frequently in grounded theory studies, with the aim of providing clinicians with the skills to critically review studies using this methodology.

    1975-01-01

    A coordinated research program was followed using a soil injection method which employed /sup 32/P-labelled superphosphate solution. The technique was applied for determining the root activity distribution of various crops. Field experiments were carried out in Uganda on bananas, Spain and Taiwan on citrus, Ghana on cocoa, Columbia and Kenya on coffee, and Ivory Coast and Malaysia on oil palms, to study the patterns of root activity as a function of depth and distance from the tree base, soil type, tree age and season. A few weeks after injection, leaf samples of similar age were taken from well-defined morphological positions on the tree and analyzed for /sup 32/P. The activity of the label in the sample reflects the root activity at the various positions in the soil. Some preliminary experiments were also carried out using /sup 32/P-superphosphate to evaluate the efficiency of different methods of fertilizer placement in relation to phosphate uptake by the plantation as a whole.

    When assessing the psychological suitability for the profession of a pilot, it is important to consider personality traits and psychomotor abilities. Our study aimed at estimating the role of temperamental traits as components of pilots' personality in eye-hand co-ordination. The assumption was that differences in the escalation of the level of temperamental traits, as measured with the Formal Characteristic of Behaviour-Temperament Inventory (FCB-TI), will significantly influence eye-hand co-ordination. At the level of general scores, enhanced briskness proved to be the most important trait for eye-hand co-ordination. An analysis of partial scores additionally underlined the importance of sensory sensitivity, endurance and activity. The application of eye-hand co-ordination tasks, which involve energetic and temporal dimensions of performance, helped to disclose the role of biologically-based personality traits in psychomotor performance. The implication of these findings for selecting pilots is discussed.

    Experiments were conducted to find the most effective combination of traps and lures for use in two different climates - the coastal and the desert regions of Israel. Three trials were conducted following the IAEA CRP- phase 4 protocol. Two simultaneous trials were carried out around June 1997. One was in a citrus grove in Tsrifin, the coastal region, and the other in a mango grove in Hatseva, the Arava Valley, a desert region where there has been on ongoing SIT program since January 1998. A third trial was also conducted in Tsrifin, at the same location as the first trial, but during February 1998. In all trials, the International Pheromone's McPhail Trap (IPMT) with NuLure + borax (NU+B) was the standard trap. The FA-3 attractants (ammonium acetate, putrescine, and trimethylamine) were used with water and surfactant Triton-X (wet version) or without water but with DDVP (dry version) in IPMT and Tephri traps. Treatments and traps included in the trials were: IPMT, FA-3, wet; IPMT, FA-3, dry; Tephri, FA-3, dry; Tephri, FA-3, wet. The results of these trials indicated that, at both locations, medfly populations differed greatly - 153 versus 82,500 flies at Hatseva and Tsrifin, respectively. All traps caught more females than males. At Tsrifin, the Tephri, FA-3 traps outperformed the IPMT, NU+B, capturing 4 to 5 times more than standard (IPMT,NU+B). The addition of water to the traps at this location resulted in a slight decrease in captures. At Hatseva, the addition of water improved capturing in both IPMT and Tephri traps. Replacing the water with ethylene glycol resulted in the highest capture level indicating the importance of humidity to the trap performance. (author)

    International Nuclear Information System (INIS)

    1997-03-01

    Adverse effects also appear within the agroecosystem itself. Intensive use of broad spectrum insecticides can reduce populations of insect parasites and predators; as a result, pest populations may be inadequately controlled. This, in turn, can lead to the need of more frequent use of pesticides and to the appearance of secondary pests. We are slowly beginning to understand how natural enemies and the other non-target fauna are affected by pesticide use in a few agroecosystems in the developed countries. The knowledge about these matters in developing countries is very rudimentary. The objectives of this programme were to increase the knowledge of how pesticides affect the agroecosystem especially pest-natural enemy interactions and the non-target fauna within and outside African agroecosystem. Chlorinated hydrocarbon pesticides were used as representing the compounds most likely to produce undesirable consequences. This TECDOC reports the accomplishments of the programme which was financed by the Swedish International Development Authority (SIDA). Refs, figs, tabs

  16. Bulk hydrogen analysis, using neutrons. Final report of the first research co-ordination meeting

    International Nuclear Information System (INIS)

    1997-07-01

    There are many situations when hydrogen is required to be measured in a bulk medium. For this reason neutrons are used due to their high penetrating power in dense material. In addition, the mass attenuation coefficient for neutrons in hydrogen is significantly larger than for all other elements, meaning that neutrons have a higher probability of interacting with hydrogen than with other elements in the sample matrix. This CRP was recommended for further development of the techniques and new applications in the following areas: Fast Neutron/Gamma Transmission Technique; Digital Neutron Imaging; Hydrogen Detection by Epithermal Neutrons; Microscopic Behaviour of Hydrogen in Bulk Materials

    Mice were immunized with semen and natural PSA, following three different schemes. Splenocytes from two hyper immune animals were fused with the P3/x63.Ag8.653 myeloma under conventional hybridoma procedures. Stable hybrid cell cultures secreting antibodies specific to natural PSA were obtained by cloning dilutions procedures. With a group of stable hybridoma cultures we developed epitope characterization assays to determine whether the antibodies were capable of recognizing PSA. According to the recognition level in ELISA, the hybridomas were classified in different groups,. We select the best pairs of Mabs for developing a total and free PSA assays based on ELISA or IRMA format. Our total-PSA based on IRMA format presented a good correlation in comparison with CIS bio total PSA assay. We recommend our anti-PSA monoclonal antibodies to develop an IRMA assay for total PSA. Cuban free-PSA assay is under evaluation at present. (author)

    The cystic fibrosis (Cftr and multidrug resistance (Mdr1) genes encode structurally similar proteins which are members of the ABC transporter superfamily. These genes exhibit complementary patterns of expression in vivo, suggesting that the regulation of their expression may be co-ordinated. We have tested this hypothesis in vivo by examining Cftr and Mdr1 expression in cystic fibrosis knockout transgenic mice (Cftr(tm1CAM)). Cftr mRNA expression in Cftr(tm1CAM)/Cftr(tm1CAM) mice was 4-fold reduced in the intestine, as compared with littermate wild-type mice. All other Cftr(tm1CAM)/Cftr(tm1CAM) mouse tissues examined showed similar reductions in Cftr expression. In contrast, we observed a 4-fold increase in Mdr1 mRNA expression in the intestines of neonatal and 3- to 4-week-old Cftr(tm1CAM)/Cftr(tm1CAM) mice, as compared with age-matched +/+ mice, and an intermediate level of Mdr1 mRNA in heterozygous Cftr(tm1CAM) mice. In 10-week-old, Cftr(tm1CAM)/Cftr(tm1CAM) mice and in contrast to the younger mice, Mdr1 mRNA expression was reduced, by 3-fold. The expression of two control genes, Pgk-1 and Mdr2, was similar in all genotypes, suggesting that the changes in Mdr1 mRNA levels observed in the Cftr(tm1CAM)/Cftr(tm1CAM) mice are specific to the loss of Cftr expression and/or function. These data provide further evidence supporting the hypothesis that the regulation Cftr and Mdr1 expression is co-ordinated in vivo, and that this co-ordinate regulation is influenced by temporal factors.

  1. Co-ordination of physiological and morphological responses of stomata to elevated [CO2] in vascular plants.

    Plant stomata display a wide range of short-term behavioural and long-term morphological responses to atmospheric carbon dioxide concentration ([CO(2)]). The diversity of responses suggests that plants may have different strategies for controlling gas exchange, yet it is not known whether these strategies are co-ordinated in some way. Here, we test the hypothesis that there is co-ordination of physiological (via aperture change) and morphological (via stomatal density change) control of gas exchange by plants. We examined the response of stomatal conductance (G(s)) to instantaneous changes in external [CO(2)] (C(a)) in an evolutionary cross-section of vascular plants grown in atmospheres of elevated [CO(2)] (1,500 ppm) and sub-ambient [O(2)] (13.0 %) compared to control conditions (380 ppm CO(2), 20.9 % O(2)). We found that active control of stomatal aperture to [CO(2)] above current ambient levels was not restricted to angiosperms, occurring in the gymnosperms Lepidozamia peroffskyana and Nageia nagi. The angiosperm species analysed appeared to possess a greater respiratory demand for stomatal movement than gymnosperm species displaying active stomatal control. Those species with little or no control of stomatal aperture (termed passive) to C(a) were more likely to exhibit a reduction in stomatal density than species with active stomatal control when grown in atmospheres of elevated [CO(2)]. The relationship between the degree of stomatal aperture control to C(a) above ambient and the extent of any reduction in stomatal density may suggest the co-ordination of physiological and morphological responses of stomata to [CO(2)] in the optimisation of water use efficiency. This trade-off between stomatal control strategies may have developed due to selective pressures exerted by the costs associated with passive and active stomatal control.

    The EC-FP7 project COMET (June 2013 - May 2017) intends to strengthen the pan-European research initiative on the impact of radiation on man and the environment by facilitating the integration of 'radioecological' research. The COMET consortium currently has thirteen partners; eight from EU member states, two from Norway, two from Ukraine and one from Japan. COMET operates in close association with the FP7-STAR Network of Excellence[1]and the Radioecology Alliance[2], COMET will develop initiatives to encourage organisations from the European (and larger) radioecological research community to join the Radioecology Alliance to help address the priorities identified in the Strategic Research Agenda (SRA) for radioecological research. Capacity, competence and skills in radioecology will thus be strengthened at a pan-European level. Mechanisms for knowledge exchange, dissemination and training will be established to enhance and maintain European capacity, competence and skills in radioecology, partially through an open access web site, topical workshops and training activities. COMET will develop innovative mechanisms for joint programming and implementation of radioecological research. Mechanisms for planning and carrying out joint research activities in radioecology will be developed based on the scientific requirements identified in the SRA and via interaction with a wide range of stakeholders. COMET will strengthen the bridge with other radiation protection and ecological communities. A roadmap and associated implementation plan is being developed in collaboration with the Radioecology Alliance and the allied platforms on low dose risk research (MELODI[3]), and emergency management research (NERIS[4]) and the radioecology community at large who is invited to become associated to the development of roadmap and implementation plan.

    EPOS Thematic Core Service ANTHROPOGENIC HAZARDS (TCS AH) aims to create new research opportunities in the field of anthropogenic hazards evoked by exploitation of georesources. TCS AH, based on the prototype built in the framework of the IS-EPOS project (https://tcs.ah-epos.eu/), financed from Polish structural funds (POIG.02.03.00-14-090/13-00), is being further developed within EPOS IP project (H2020-INFRADEV-1-2015-1, INFRADEV-3-2015). TCS AH is designed as a functional e-research environment to ensure a researcher the maximum possible freedom for in silico experimentation by providing a virtual laboratory in which researcher will be able to create own workspace with own processing streams. The unique integrated RI is: (i) data gathered in the so- called "episodes", comprehensively describing a geophysical process, induced or triggered by human technological activity, which under certain circumstances can become hazardous for people, infrastructure and the environment and (ii) problem-oriented, specific high-level services, with the particular attention devoted to methods analyzing correlations between technology, geophysical response and resulting hazard. Services to be implemented are grouped within six blocks: (1) Basic services for data integration and handling; (2) Services for physical models of stress/strain changes over time and space as driven by geo-resource production; (3) Services for analysing geophysical signals; (4) Services to extract the relation between technological operations and observed induced seismic/deformation; (5) Services to quantitative probabilistic assessments of anthropogenic seismic hazard - statistical properties of anthropogenic seismic series and their dependence on time-varying anthropogenesis; ground motion prediction equations; stationary and time-dependent probabilistic seismic hazard estimates, related to time-changeable technological factors inducing the seismic process; (6) Simulator for Multi

    The relation between muscle pain, muscle activity, and muscle co-ordination is still controversial. The present human study investigates the influence of experimental muscle pain on resting, static, and dynamic muscle activity. In the resting and static experiments, the electromyography (EMG) activity and the contraction force of m. tibialis anterior were assessed before and after injection of 0.5 ml hypertonic saline (5%) into the same muscle. In the dynamic experiment, injections of 0.5 ml hypertonic saline (5%) were performed into either m. tibialis anterior (TA) or m. gastrocnemius (GA) and the muscle activity and co-ordination were investigated during gait on a treadmill by EMG recordings from m. TA and m. GA. At rest no evidence of EMG hyperactivity was found during muscle pain. The maximal voluntary contraction (MVC) during muscle pain was significantly lower than the control condition (P Fibromyalgia and Myofascial Pain. Elsevier, Amsterdam, 1993, pp. 311-327.) which predicts increased activity of antagonistic muscle and decreased activity of agonistic muscle during experimental and clinical muscle pain.

    Abnormal accumulation of alpha-synuclein in Lewy bodies is a neuropathological hallmark of both sporadic and familial Parkinson's disease (PD). Although mutations in alpha-synuclein have been identified in autosomal dominant PD, the mechanism by which dopaminergic cell death occurs remains unknown. We investigated transcriptional changes in neuroblastoma cell lines transfected with either normal or mutant (A30P or A53T) alpha-synuclein using microarrays, with confirmation of selected genes by quantitative RT-PCR. Gene products whose expression was found to be significantly altered included members of diverse functional groups such as stress response, transcription regulators, apoptosis-inducing molecules, transcription factors and membrane-bound proteins. We also found evidence of altered expression of dihydropteridine reductase, which indirectly regulates the synthesis of dopamine. Because of the importance of dopamine in PD, we investigated the expression of all the known genes in dopamine synthesis. We found co-ordinated downregulation of mRNA for GTP cyclohydrolase, sepiapterin reductase (SR), tyrosine hydroxylase (TH) and aromatic acid decarboxylase by wild-type but not mutant alpha-synuclein. These were confirmed at the protein level for SR and TH. Reduced expression of the orphan nuclear receptor Nurr1 was also noted, suggesting that the co-ordinate regulation of dopamine synthesis is regulated through this transcription factor.

    EPOS, the European Plate Observing System, is a long-term plan to facilitate the integrated use of data, data products, software and services, available from distributed Research Infrastructures (RI), for solid Earth science in Europe. Indeed, EPOS integrates a large number of existing European RIs belonging to several fields of the Earth science, from seismology to geodesy, near fault and volcanic observatories as well as anthropogenic hazards. The EPOS vision is that the integration of the existing national and trans-national research infrastructures will increase access and use of the multidisciplinary data recorded by the solid Earth monitoring networks, acquired in laboratory experiments and/or produced by computational simulations. The establishment of EPOS will foster the interoperability of products and services in the Earth science field to a worldwide community of users. Accordingly, the EPOS aim is to integrate the diverse and advanced European Research Infrastructures for solid Earth science, and build on new e-science opportunities to monitor and understand the dynamic and complex solid-Earth System. One of the EPOS Thematic Core Services (TCS), referred to as Satellite Data, aims at developing, implementing and deploying advanced satellite data products and services, mainly based on Copernicus data (namely Sentinel acquisitions), for the Earth science community. This work intends to present the technological enhancements, fostered by EPOS, to deploy effective satellite services in a harmonized and integrated way. In particular, the Satellite Data TCS will deploy five services, EPOSAR, GDM, COMET, 3D-Def and MOD, which are mainly based on the exploitation of SAR data acquired by the Sentinel-1 constellation and designed to provide information on Earth surface displacements. In particular, the planned services will provide both advanced DInSAR products (deformation maps, velocity maps, deformation time series) and value-added measurements (source model

  11. Lipid binding to cytoglobin leads to a change in haem co-ordination: a role for cytoglobin in lipid signalling of oxidative stress.

    Cytoglobin is a recently discovered hexa-co-ordinate haemoglobin that does not appear to function as a classical oxygen-binding protein. Its function is unknown and studies on the effects of changes in its expression have not decisively determined its role within the cell. In the present paper, we report that the protein is transformed from hexa-co-ordinate to penta-co-ordinate on binding a lipid molecule. This transformation occurs with the ferric oxidation state of the protein, but not the ferrous state, indicating that this process only occurs under an oxidative environment and may thus be related to redox-linked cell signalling mechanisms. Oleate binds to the protein in a 1:1 stoichiometry and with high affinity (K(d)=0.7 μM); however, stopped-flow kinetic measurements yield a K(d) value of 110 μM. The discrepancy between these K(d) values may be rationalized by recognizing that cytoglobin is a disulfide-linked dimer and invoking co-operativity in oleate binding. The lipid-induced transformation of cytoglobin from hexa-co-ordinate to penta-co-ordinate does not occur with similar hexa-co-ordinate haemoglobins such as neuroglobin, and therefore appears to be a unique property of cytoglobin among the haemoglobin superfamily. The lipid-derived transformation may explain why cytoglobin has enhanced peroxidatic activity, converting lipids into various oxidized products, a property virtually absent from neuroglobin and much decreased in myoglobin. We propose that the binding of ferric cytoglobin to lipids and their subsequent transformation may be integral to the physiological function of cytoglobin, generating cell signalling lipid molecules under an oxidative environment.

  12. The theorization of social co-ordinations in differentiated societies: the theory of generalized symbolic media in Parsons, Luhmann and Habermas.

    The problem of the differentiation of societies is at the core of the sociological imagination about the rise of modernity. In postwar sociology, T. Parsons developed the theory of generalized symbolic media in the mid-1960s to tackle, theoretically and historically, the issue of differentiation. According to him, the interchange media are defined as resources oriented to exchange processes between the subsystems of the social system. Starting with money, Parsons argues that the remaining media (power, influence, and value-commitments) have a set of characteristics defined as common properties for all media. After this first formulation, contemporary theorists such as Niklas Luhmann and Jürgen Habermas have developed and modified the Parsonian theory: Luhmann rejects the idea of interchange and proposes the use of communication; Habermas distinguishes between steering and communication media. In all three cases, the focus of the theory is on the characterization of the strongest dynamics of social co-ordination present in differentiated societies. A major result of these developments is the inclusion of new dimensions on which to conceive the properties of media, not only those of money but also language. Beyond differences, then, it is proposed that there is only one theory of generalized symbolic media which can be understood as a progressive research programme, in Lakatos' terms. Finally, the hand-in-hand evolution between the theory of media and Habermas' and Luhmann's re-conceptualizations on societal differentiation in contemporary societies will also be revealed.

Sincesuburban traffic means frequent slopping, and since the enginedriver does not use the rheostatic brake regularly, but only theair brake, the wear of the brake lining and wheels is higher, andthe heat load on the brake elements is substantial. By regularapplication of rheostatic brake, the air brake could be LLSed lessthus contributing to a lower wear of the friction elements.The presented solution for the modification of the brakeconsists of co-ordinated and automatic action of the rheostaticand air brake with every braking

    2012-01-06

    If maternal atopy and environmental exposure affect prenatal Th cell development, the maternal and fetal immune systems should display common Th1/Th2 phenotypes. To test this hypothesis, we studied maternal and neonatal blood samples from mothers with total serum IgE ordinate IFN-γ production from paired maternal and fetal mononuclear cells, accompanied by co-ordinate increases in activated CD4+CD69+ cells that display the CCR4+Th2 and CXCR3+ Th1 phenotypes. Maternal and fetal CD4+CXCR3+ T cells were subsequently identified as the major producers of IFN-γ. The data established that a transplacental nexus exists during normal pregnancy and that fetal Th cell responses may be biased by the maternal immune system.

    This paper sets out to explore the effects of voxel resolution, from 2 mm down to 0.1 mm for Cartesian co-ordinates and the differences between Cartesian and spherical polar co-ordinates for a standardized test-bed model of the eye. This model was taken from the work of Yoriyaz et al (2005 Radiat. Prot. Dosim. 115 316-9) who have developed a detailed geometric description of the eye including choroid, retina, sclera, lens, cornea, anterior chamber, vitreous humour and optic nerve for ophthalmic brachytherapy. The spherical co-ordinate model has radial and angular steplengths of 0.1 mm and 0.25°, respectively. The current density averaged over 1 cm(2) and the 99th percentile value of the induced electric field have been calculated in the retina and central nervous system for uniform magnetic fields. The Cartesian co-ordinate calculations proceed in a sequence of grids at 2, 1, 0.5, 0.2 and 0.1 mm resolution with the potentials from the previous calculation at a coarser grid providing the boundary conditions on the finer grid. The 0.2 mm grid provides the boundary conditions for the spherical polar calculations. Comparisons are made with the International Commission on Non-Ionizing Radiation Protection reference levels.

    Co-ordination properties of diglycol-amide (DGA) to trivalent curium and to the trivalent lanthanides were studied by the EXAFS, the XRD and the XPS methods. The structural determinations by both the crystal XRD and the solution EXAFS methods showed that the DGA co-ordinated to the trivalent lanthanide ion in a tridentate fashion: co-ordination of three oxygen atoms of each ligand to the metal ion. The bond distances of Er-O (carbonyl) and Er-O (ether) in the Er-DGA complex were 2.35 Angstrom, and 2.46 Angstrom, respectively, while the atom distances of Cm-O (carbonyl) and Cm-O (ether) in the Cm-DGA complex were 2.42 Angstrom and 3.94 Angstrom, respectively from the EXAFS data for the Cm-DGA complex. Accordingly, the DGA would behave only as a semi-tridentate in the co-ordination to trivalent curium in solution. We determined the valence band structures of the Er-DGA complex by the XPS in order to clarify the bond properties of the complex, and assigned the XPS spectrum by using the DV-DS molecular orbital calculation method.

    The unsymmetrical tridentate benzimidazole-pyridine-carboxamide units in ligands L1-L4 react with trivalent lanthanides, Ln(III), to give the nine-co-ordinate triple-helical complexes [Ln(Li)3]3+ (i = 1-4) existing as mixtures of C3-symmetrical facial and C1-symmetrical meridional isomers. Although the beta13 formation constants are 3-4 orders of magnitude smaller for these complexes than those found for the D3-symmetrical analogues [Ln(Li)3]3+ (i = 5-6) with symmetrical ligands, their formation at the millimolar scale is quantitative and the emission quantum yield of [Eu(L2)3]3+ is significantly larger. The fac-[Ln(Li)3]3+ mer-[Ln(Li)3]3+ (i = 1-4) isomerisation process in acetonitrile is slow enough for Ln = Lu(III) to be quantified by 1H NMR below room temperature. The separation of enthalpic and entropic contributions shows that the distribution of the facial and meridional isomers can be tuned by the judicious peripheral substitution of the ligands affecting the interstrand interactions. Molecular mechanics (MM) calculations suggest that one supplementary interstrand pi-stacking interaction stabilises the meridional isomers, while the facial isomers benefit from more favourable electrostatic contributions. As a result of the mixture of facial and meridional isomers in solution, we were unable to obtain single crystals of 1:3 complexes, but the X-ray crystal structures of their nine-co-ordinate precursors [Eu(L1)2(CF3SO3)2(H2O)](CF3SO3)(C3H5N)2(H2O) (6, C45H54EuF9N10O13S3, monoclinic, P2(1)/c, Z = 4) and [Eu(L4)2(CF3SO3)2(H2O)](CF3SO3)(C4H4O)(1.5) (7, C51H66EuF9N8O(15.5)S3, triclinic, P1, Z = 2) provide crucial structural information on the binding mode of the unsymmetrical tridentate ligands.

    easy integration into other energy planning or analysis tools. DECADES was thus organized as a data management system rather than as an overall or long range energy planning tool. In 1997, the IAEA initiated a co-ordinated research project (CRP) on Case Studies to Assess and Compare Different Sources in Sustainable Energy and Electricity Supply Strategies under the aegis of the DECADES project to conduct a series of national studies using the DECADES package (DECPAC). Under this CRP, experts from more than twenty countries utilized databases and methodologies developed and reviewed under the DECADES project to carry out national comparative assessment studies. At a final Research Co-ordination Meeting (RCM), held from 14 to 16 December 1999, meeting participants agreed on the format of executive summaries to be prepared for each of the national case studies. This publication summarizes the results obtained and the lessons learned from national case studies carried out under the CRP. The report is intended primarily for managers and senior experts in governmental organizations, research institutes and power utilities who are involved in energy and environmental analysis, interpretation of model results and translation into decision and policy making

  4. Studies on the distribution of platinum in tumour-bearing rats after the administration of platinum co-ordination complexes used in cancer chemotherapy

    Platinum co-ordination complexes like dichlorodiamineplatinum(II) (DDP) feature broad spectrum antitumour activity which, however, is marred by a certain toxicity related especially to renal tubular damage. The activity of such drugs depends on the chemical structure of the complexes, with changes in the ligands resulting in changes in their antitumour activity and toxicity. Assessments of the biological and toxicological effects of recently synthesized complexes must include distribution studies of platinum in the body. It is demonstrated that instrumental neutron activation analysis can be used for these studies because of its accuracy, precision and the low detection limit for platinum (approximately equal to 2 ng), when a standardized method is used. The time-dependent retention of platinum was determined in blood, liver, kidneys and cells of ascitic Walker 256 carcinosarcoma in tumour-bearing rats and controls after the administration of the cis-Pt(Gly-Gly-0Et) 2 Cl 2 complex. Two series of experiments, one with the therapeutic amount of the drug (80 mg/kg body weight) and one low-dose experiment with 1/100 of this amount, were carried out. The results of both experiments are discussed with regard to changes in the platinum concentration with time (0-48 h) in the different samples. From the data a selective uptake of the drug by the tumour cells, causing their destruction, is deduced. Because this drug has shown excellent antitumour activity, this observed selectivity suggests promise for its application in cancer chemotherapy, although platinum retention is still found in the kidneys, which might cause renal tubular damage. This latter aspect requires further clinical research to evaluate fully its effects. (author)

    Escherichia coli O157:H7 is a zoonotic pathogen that can express a type III secretion system (TTSS) considered important for colonization and persistence in ruminants. E. coli O157:H7 strains have been shown to vary markedly in levels of protein secreted using the TTSS and this study has confirmed that a high secretion phenotype is more prevalent among isolates associated with human disease than isolates shed by healthy cattle. The variation in secretion levels is a consequence of heterogeneous expression, being dependent on the proportion of bacteria in a population that are actively engaged in protein secretion. This was demonstrated by indirect immunofluorescence and eGFP fusions that examined the expression of locus of enterocyte effacement (LEE)-encoded factors in individual bacteria. In liquid media, the expression of EspA, tir::egfp, intimin, but not map::egfp were co-ordinated in a subpopulation of bacteria. In contrast to E. coli O157:H7, expression of tir::egfp in EPEC E2348/69 was equivalent in all bacteria although the same fusion exhibited variable expression when transformed into an E. coli O157:H7 background. An E. coli O157:H7 strain deleted for the LEE demonstrated weak but variable expression of tir::egfp indicating that the elements controlling the heterogeneous expression lie outside the LEE. The research also demonstrated the rapid induction of tir::egfp and map::egfp on contact with bovine epithelial cells. This control in E. coli O157:H7 may be required to limit exposure of key surface antigens, EspA, Tir and intimin during colonization of cattle but allow their rapid production on contact with bovine gastrointestinal epithelium at the terminal rectum.

    Magnetotactic bacteria synthesize magnetosomes comprised of membrane-enveloped single crystalline magnetite (Fe3 O4 ). The size and morphology of the nano-sized magnetite crystals (Mms (Mms5, Mms6, Mms7, and Mms13), was previously isolated from the surface of cubo-octahedral magnetite crystals in Magnetospirillum magneticum strain AMB-1. Analysis of an mms6 gene deletion mutant suggested that the Mms6 protein plays a major role in the regulation of magnetite crystal size and morphology. In this study, we constructed various mms gene deletion mutants and characterized the magnetite crystals formed by the mutant strains. Comparative analysis showed that all mms genes were involved in the promotion of crystal growth in different manners. The phenotypic characterization of magnetites also suggested that these proteins are involved in controlling the geometries of the crystal surface structures. Thus, the co-ordinated functions of Mms proteins regulate the morphology of the cubo-octahedral magnetite crystals in magnetotactic bacteria. © 2014 John Wiley & Sons Ltd.

    The activities of 3-hydroxy-3-methylglutaryl-coenzyme A reductase, sterol methyl transferase 1 and sterol acyltransferase, key enzymes involved in phytosterol biosynthesis were shown to be co-ordinately regulated during oilseed rape ( Brassica napus L.) and tobacco ( Nicotiana tabacum L.) seed development. In both plants, enzyme activities were low during the initial stages of seed development, increasing towards mid-maturation where they remained stable for a time, before declining rapidly as the oilseeds reached maturity. During seed development, the level of total sterols increased 12-fold in tobacco and 9-fold in rape, primarily due to an increase in steryl ester production. In both seed tissues, stages of maximum enzyme activity coincided with periods of high rates of sterol production, indicating developmental regulation of the enzymes to be responsible for the increases in the sterol content observed during seed development. Consistent with previous studies the data presented suggest that sterol biosynthesis is regulated by two key steps, although there may be others. The first is the regulation of carbon flux into the isoprenoid pathway to cycloartenol. The second is the flux from cycloartenol to Delta(5)-end-product sterols. The implications of the results in terms of enhancing seed sterol levels by genetic modification are also discussed.
