    1995-12-31

    Since 1992 Brookhaven National Laboratory (BNL) and Pacific Northwest Laboratory (PNL), acting on behalf of the U.S. Department of Energy, executed the first stage of the Cracow Program of Energy Conservation and Clean Fossil Fuels, called also American-Polish Program of Actions for Elimination of Low Emission Sources in Cracow. The main contractor for BNL and PNL was the Cracow Development Office (BRK). The interest in improving the condition of Cracow air results from the fact that the standard for permissible air pollution was exceeded several times in Cracow and especially within the central part of the town. Therefore, air pollution appeared one of the most important problems that faced the municipal authorities. It followed from monitoring investigations that the high level of air pollutant concentration is caused by in-home coal-fired tile stoves operated in winter seasons and by coal- and coke-fired boiler houses simulated mainly in the central part of the town. The results obtained in first stage are presented. This paper is an attempt to formulate conclusions drawn from these works and recommendations with regard to the future policy of the town authorities; selected results are presented to clarify or illustrate the conclusions.

    The statistics currently available (year 1986) show that 40% of the declared events have a human component. The desire to reduce the number and importance of such events which, in varying degrees, affect the safety and availability of the nuclear installations has lead the Nuclear and Fossil Generation Division (SPT) of EDF to set up a system for gathering data concerning human errors. How does SPT approach this problem? 1. - By gathering data. 2. - By having improvements made. 3. - By making allowance for human factors in new designs. All three stages are described separately, and the first two of them are then analysed in detail. The case studies mentioned in the second part are either completed, in the process of validation or being carried out and integrated, in which case the information available at the present time is not sufficiently complete to enable assessment of information feedback. Nevertheless, insofar as possible, each case is described in terms of methods, results and proposed action. In certain instances, a simplified synopsis is given. 25 refs. (author)

    Full Text Available The Tier 2 Program of the Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social Programmes is designed for adolescents with significant psychosocial needs, and its various programs are designed and implemented by social workers (program implementers for specific student groups in different schools. Using subjective outcome evaluation data collected from the program participants (Form C at 207 schools, the program implementers were asked to aggregate data and write down five conclusions (n = 1,035 in their evaluation reports. The conclusions stated in the evaluation reports were further analyzed via secondary data analyses in this study. Results showed that the participants regarded the Tier 2 Program as a success, and was effective in enhancing self-understanding, interpersonal skills, and self-management. They liked the experiential learning approach and activities that are novel, interesting, diversified, adventure-based, and outdoor in nature. They also liked instructors who were friendly, supportive, well-prepared, and able to bring challenges and give positive recognition. Most of the difficulties encountered in running the programs were related to time constraints, clashes with other activities, and motivation of participants. Consistent with the previous evaluation findings, the present study suggests that the Tier 2 Program was well received by the participants and that it was beneficial to the development of the program participants.

In the experimental implementation phase, 52 schools participated in the program. Based on subjective outcome evaluation data collected from the program participants (Form A and program implementers (Form B in each school, the program implementers were invited to write down five conclusions based on an integration of the evaluation findings (N = 52. The conclusions stated in the 52 evaluation reports were further analyzed via secondary data analyses in this paper. Results showed that most of the conclusions concerning perceptions of the Tier 1 Program, instructors, and effectiveness of the programs were positive in nature. There were also conclusions reflecting the respondents’ appreciation of the program. Finally, responses on the difficulties encountered and suggestions for improvements were observed. In conjunction with the previous evaluation findings, the present study suggests that the Tier 1 Program was well received by the stakeholders and the program was beneficial to the development of the program participants.

  11. Conclusions Drawn from the Investigation of LOCA-Induced Insulation Debris Generation and its Impact on Emergency Core Cooling (ECC) at German NPPs - Approach Taken by / Perspective of The German TSO (TuV)

    2004-01-01

    Initiated by the Barsebaeck incident in 1992 and the following activities related to the LOCA-induced insulation debris generation and its impact on emergency core cooling, investigations on German PWRs and BWRs were performed in these areas. The investigations on the German BWRs were carried out in detail immediately after the Barsebaeck incident in the years 1992 through 1994. Detailed investigations on the German PWRs started after the issue of the OECD report in 1996. Therefore the investigations on the impact of LOCA-induced insulation debris generation on strainer plugging carried out in Germany in the last years were focused mainly on the German PWRs. In the framework of these investigations of the German PWRs, the relevant parameters and phenomena were investigated in detail by the plant owners in the years from 1997 through 1999. The results were summarised in reports for each plant. The main results of the investigations conducted by the plant owners were that the plant owners considered backfitting in German PWRs is not necessary to guarantee emergency core cooling following a LOCA with insulation debris generation. As the technical support organisation for the German Bavarian and Hessian state authority, the TUV Suddeutschland was called upon to examine these investigations and the conclusions drawn by the plant owners. We compared each of the parameters and phenomena against the state of knowledge. The results of our examination in 1999 showed that the investigations of the plant owners were generally correct, but we stated also, that due to existing uncertainties, further investigations are necessary to validate the results. To meet these demands, the plant owners installed a working group for planning and performing newer, more realistic large-scale experiments (scaling factor 1:4) to investigate the transport mechanism of the insulation material within the containment sump, the head loss at the strainers and to estimate the amount of insulation

  12. The six most essential questions in psychiatric diagnosis: a pluralogue. Part 4: general conclusion

    Full Text Available Abstract In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined.

    The cellular redox balance seems an important modulator under heavy metal stress. While for other heavy metals these processes are well studied, oxidative stress related responses are also known to be triggered under uranium stress but information remains limited. This study aimed to further unravel the mechanisms by which plants respond to uranium stress. Seventeen-day-old Arabidopsis thaliana seedlings, grown on a modified Hoagland solution under controlled conditions, were exposed to 0, 0.1, 1, 10 and 100 μM uranium for 1, 3 and 7 days. While in Part I of this study oxidative stress related responses in the roots were discussed, this second Part II discusses oxidative stress related responses in the leaves and general conclusions drawn from the results of the roots and the leaves will be presented. As several responses were already visible following 1 day exposure, when uranium concentrations in the leaves were negligible, a root-to-shoot signaling system was suggested in which plastids could be important sensing sites. While lipid peroxidation, based on the amount of thiobarbituric acid reactive compounds, was observed after exposure to 100 μM uranium, affecting membrane structure and function, a transient concentration dependent response pattern was visible for lipoxygenase initiated lipid peroxidation. This transient character of uranium stress responses in leaves was emphasized by results of lipoxygenase (LOX2) and antioxidative enzyme transcript levels, enzyme capacities and glutathione concentrations both in time as with concentration. The ascorbate redox balance seemed an important modulator of uranium stress responses in the leaves as in addition to the previous transient responses, the total ascorbate concentration and ascorbate/dehydroascorbate redox balance increased in a concentration and time dependent manner. This could represent either a slow transient response or a stable increase with regard to plant acclimation to uranium stress. Copyright

    In the tritium balance of pressurized water reactors, using boric acid and lithium in the cooling water, contribution of the tritium produced by fission, diffusing through the zircalloy of the fuel cladding estimated to 0.1%, was not in agreement with quantities measured in reactors. It is still difficult to estimate what percentage is represented by the tritium formed by fission in the fuel, owing to diffusion through cladding. The tritium balance in different working nuclear power stations is consequently of interest. The tritium balance method in the water of the cooling circuit of PWR is fast and experimentally simple. It is less sensitive to errors originating from fission yields than balance of tritium produced by fission in the fuel. A tritium balance in the water of the cooling circuit of Biblis-A, with a specific burn-up of 18000 MWd/t gives a better precision. Diffusion rate of tritium produced by fission was less than 0.2%. So low a contribution is a justification to the use of lithium with an isotopic purity of 99.9% of lithium 7 to limit at a low value the residual lithium 6 [fr

    Full text: The EVIDOS project, supported by the European Commission within the 5th Framework Programme, aims at evaluating state of the art dosimetry techniques in representative work-places of the nuclear industry. Seven European institutes with recognized expertise in radiation protection instruments and methods joined efforts with end users at nuclear power plants, at fuel processing and reprocessing plants, and at transport and storage facilities. A particular task of the project was to develop methods to characterize the neutron component of mixed radiation fields at workplaces and to derive reference values of radiation protection quantities from energy and direction distributions of the neutron fluence. While other presentations at this workshop describe the methods developed and the instruments used, this presentation will summarize the main results, draw conclusions and discuss recommendations relevant to routine monitoring. The final results from the project include a catalogue with spectra and dosimetric data for 14 different workplace fields (boiling water reactor, pressurized water reactor, research reactor, fuel processing, storage of spent fuel), instruments and procedures to derive reference values for personal dose equivalent and other radiation protection quantities, and novel personal dosemeters for mixed radiation and results on their dosimetric and technical performance. A number of questions will be addressed in the presentation, including: which methods allow to determine H*(10) and H p (10) in complex mixed n/γ radiation fields with acceptable uncertainty?; what is the influence of the energy and direction distributions of neutrons on the ratios between H*(10), H p (10) and E?; how much do the readings of area monitors deviate from H*(10) and do they give conservative estimates of H p (10) and E?; how much do the readings of personal dosemeters deviate from H p (10) and do they give conservative estimates of E?; do new active (electronic

    . Nevertheless, the simulations provided additional evidence of the high pH buffer capacity of the Opalinus Clay. The results from the microbiological investigations do not allow unambiguous identification of the origin of the microbial population in the borehole. Possible sources were the drilling procedure, the artificial porewater, and perhaps some revival of indigenous dormant strains. Regardless of the origin of the microbes, the results from the PC experiment underlined the importance of anaerobic microbial activity in the 'disturbed' Opalinus Clay, facilitated by the introduction of space, water and organic material, in rapidly establishing very reducing conditions. The PC experiment also yielded valuable insight with regard to the safety of a high-level radioactive waste repository emplaced in Opalinus Clay. Anaerobic microbial perturbations in the clay host rock may occur from the construction and excavation procedures and emplaced organic by-products. The resulting effects on porewater chemistry, i.e., especially on pH and Eh, may affect the mobility of radionuclides eventually released from the waste. However, the overall results of the PC experiment suggest that such effects are temporary and spatially limited because of the large buffering capacity and diffusive properties of the clay formation. Nevertheless, the results also indicate that the amounts of organic materials in a high-level waste repository should be kept small in order to achieve background conditions within a short time period after repository closure. A further conclusion from the PC experiment is that commonly used equipment materials may not display commonly assumed inert behaviour. This particularly holds for the gel-type 'robust' reference electrodes, which may release substantial amounts of glycerol.

  2. Developing of risk-hedging CO2-emission policy. Part II: risks associated with measures to limit emissions, synthesis and conclusions

    Harvey, L.D.D.

    1996-01-01

    This paper is Part II of a two-part series in which the risk associated with unrestrained greenhouse-gas emissions, and with measures to limit emissions, are reviewed. The following risks associated with these efforts to limit CO 2 emissions are reviewed here: (1) resources might be diverted from other urgent needs; (2) economic growth might be reduced; (3) reduction measures might cost more than expected; (4) early action might cost more than later action; (5) reduction measures might have undesired side effects; (6) reduction measures might require heavy-handed government intervention; and (7) reduction measures might not work. With gradual implementation of a diversified portfolio of measures, these risks can be greatly reduced. Based on the review of risks associated with measures to limit emissions here, and the review of the risk associated with unrestrained emissions presented in Part I, it is concluded that a reasonable near-term (20-30 year) risk hedging strategy is one which seeks to stabilize global fossil CO 2 emissions at the present (early 1990s) level. This is turn implies an emission reduction of 26% for industrialized countries as a whole and 40-50% for Canada and the USA if developing country emissions are to increase by no more than 60%, which in itself would require major assistance from the industrialized countries. The framework and conclusions presented here are critically compared with so-called optimization frameworks. 82 refs., 2 figs., 2 tabs

    In part I we described the gasification technology and characterised the physio-chemical properties and environmental impacts of the rice husk char (RHC) by-product. In part II we present summary results from field trials using the RHC, and provide an estimate of the carbon abatement and economic evaluation of the system. Statistically significant yield increases are demonstrated for RHC addition in irrigated rice cultivation (33% increase in paddy rice yield for a 41.5 t (dry weight) RHC application per hectare). The carbon abatement from the RHC addition is approximately 0.42 t CO 2 t −1 rice husk; including energy generation from gasification this increases to ca. 0.86 tCO 2 t −1 . Assuming a carbon value of $5 t CO 2 t −1 , and agronomic value of $3 t −1 RHC based on the field trials, the economic value of the RHC varies from $9 t −1 (including only recalcitrant carbon) to $15 t −1 (including avoided emissions from energy production). We summarise results from parts I and II, concluding that the gasification–biochar system meets many of the criteria of sustainability, but requires better waste water management and more field trials to demonstrate repeatable agronomic efficacy of RHC application. - Highlights: ► Field trials show statistically significant rice yield increases using rice husk char (RHC). ► Carbon abatement of 0.42 t CO 2 t −1 rice husk from RHC production. ► Bioenergy generation via gasification gives carbon abatement of 0.44 t CO 2 t −1 husk. ► Total carbon abatement is therefore ca. 0.86 t CO 2 t −1 husk. ► Agronomic value from trials is $3 t −1 char; assuming $5 CO 2 t −1 , the total value of RHC is $9–$15 t −1 .

    Recent legislation has stressed the need to decide the best end-of-life (EoL) option for post-consumer products considering their full life-cycle and the corresponding overall environmental impacts. The life cycle assessment (LCA) technique has become a common tool to evaluate those impacts. The present study aimed to contribute to the better understanding of the application of this technique, by evaluating the influence of the selection of the life cycle impact assessment (LCIA) method in its results and conclusions. A specific case study was chosen, using previous information related to an anti-glare lamellae (AGL) for highway use, made with virgin and recycled high-density polyethylene (HDPE). Five distinct LCIA methods were used: Eco-indicator 99, CML 2 (2000), EPS 2000, Eco-indicator 95 and EDIP 97. Consistent results between these methods were obtained for the Climate change, Ozone layer depletion, Acidification and Eutrophication environmental indicators. Conversely, the Summer smog indicator showed large discrepancies between impact assessment methods. The work sheds light on the advantages inherent in using various LCIA methods when doing the LCA study of a specific product, thus evidencing complementary analysis perspectives.

    The paper presents conclusions and recommendations at the closing session of the NEA/OECD Workshop held at Fontenay-aux-Roses on 12-14 June 1995. The conclusions refer to issues like: public reaction to foodstuffs containing radioisotope concentrations under the danger standards, possible non-adherence of manufacturers, processors, distributors, et al, to the instructions and guidance from radiation protection specialists, integration of all the food chain factors in the elaboration of the emergency intervention programs, etc. Among the most significant recommendations the following may be mentioned: 1. Differences between different intervention levels and the maximum admissible levels agreed upon by national, regional or international nutrition authorities should be further studied; 2. Problems created by the Chernobyl accident (as for instance, the methods of treatment of food chain products containing unacceptable radioactivity concentrations) are still present and must be solved; 3. Further studies should be done on the socio-cultural aspects of the communication, particularly on the information in rural environment; 4. The preventive measures in agriculture should be implemented as rapidly as possible; 5. In elaborating programmes of agriculture countermeasures, the management of contaminated media, particularly, of forests and their effect on agriculture

    This section summarizes the presentations and Panel discussions of the 4 technical sessions of the workshop: 1 - Regulatory cooperation on generic and design specific issues, MDEP working groups (EPR, AP1000), vendor inspection co-operation, digital I and C, and codes and standards (7 presentations); 2 - Regulatory positions on siting practices and enhancements as a result of lessons learned from Fukushima accident (5 presentations); 3 - Construction experience and regulatory oversight of new reactor construction activities (6 presentations); 4 - Lessons learned from regulatory licensing reviews of new reactor designs (6 presentations). The main workshop conclusions are listed as follows: - Harmonization is a long term goal and significant progress has been made. However, this long term objective needs to be associated with short term measurable steps; - MDEP approach to tackle on one side with specific technical subjects, and to strive harmonisation on generic topics was considered appropriate; - Convergence on technical requirements is more realistic than harmonization of codes and standard; - Beneficial early engagement of different stakeholders specially at the siting stage has been acknowledged; - Need to characterise the hazards and to keep updated the safety assessment (PSR); - Land use issues are important particularly after Fukushima; - Commissioning aspects (e.g. training aspects for inspectors) should be addressed by WGRNR taking into account MDEP interaction; - Importance of WGRNR ConEx Programme: construction experience sharing is a leverage for quality and so for a future safe operation of NPPs; - Capability of licensee to follow the responsibility of design changes (could be an issue for small utilities); - Importance of Periodic Safety Reviews to review and account for the design. Finally, the WGRNR has convened that a third conference should be held in about two years time (2014- 2015)

    Taking a number of serious accidents considered to be particularly representative (Windscale, Enrico Fermi, Lucens, Browns Ferry, Three Mile Island and Saint-Laurent-des-Eaux), the paper analyses the conclusions reached in subsequent enquiries and the lessons drawn from them by the responsible authorities. While design problems sometimes come to light, it is much more generally operational safety - problems related to instructions, the training of operators, the man/machine relationship - which appears to be inadequate. The organization of relations between the different partners - builders, operators and safety bodies - likewise gives rise to some observations. Certain measures should be pursued on a broader scale in order to improve our ability to prevent serious accidents: (i) incidents important from the standpoint of safety must be identified; (ii) these incidents must be brought to the knowledge of all partners concerned, in all interested countries; (iii) the lessons drawn from them must be exchanged and compared; and (iv) the lessons must be made generally available in a directly usable form (i.e. as design modifications, changes in instructions and so on). Particular attention must be given to the problems of countries which are embarking on nuclear programmes and which, with a small number of installations, need direct and permanent access to all the lessons drawn from the operation of a large power station park, and must be able to call upon the assistance of teams from outside in the event of an accident.

    Beginning 1992, January 1 Semipalatinsk test site was transforming into large research scientific center. The National Nuclear Center (NNC) was formed on the base of site's research enterprises. The principal problems of NNC are as follows: liquidation of nuclear tests consequences; liquidation of technological infrastructure for preparation and conducting of nuclear tests, creation of technology for radioactive wastes store; implementation of atomic energy development conception in Kazakhstan, etc. Program of site conversion constantly is expanding. In this chapter measures by rehabilitation of injured population are revealed. Taking into account radioecological situation, dose loadings, demographic indexes, sick rate and mortality of population on territories exposed to site's influence Government of Kazakhstan adopted Decree on declaration of these lands of zone of ecological catastrophe. Measures on improvement of radioecological situation are reduce to following ones: determination of irradiation doses received by population during testing period; study of existing radiation contamination; study of all possible sources for dose increasing and taking into account other ones; information of population about radioecological situation and about all consequences of nuclear tests. In 1992 Supreme Soviet of Republic of Kazakhstan worked out and adopted law On social defence of citizens suffered from consequences of nuclear tests on Semipalatinsk test site. It was distinguished four zones of radiation risk. The first zone is zone of extreme risk. It is part of territory subjected to radiation contamination with dose of influence on population above 100 rem during of total period of tests conducting. To this zone belong following inhabited settlements: Budene, Dolon', Cheremushki, Mostik, Sarzhal, Isa, Sarpan, Karakoryk, Zagotskot-2. Second zone is zone of maximal radiation risk. To this zone belong inhabited settlements of following districts: Abaj, Abraly, Beskargaj

    authorities, reactor designers, and operators/ licensees perspectives on the various practices used in the regulation of nuclear power plant siting (selection, evaluation and site preparation). This session was also aimed to address issues on sites where a mixture of activities are taking place (e.g., operating units, new construction, decommissioning, etc.) including organisation of the regulators and licensee/engineering organisation, methods, systems, etc. Conclusions: In general workshop participants agreed on the need to regularly have these kind of forums to discuss relevant regulatory issues for new builds. One important aspect of this workshop was the participation of 'New Entrants'. The interaction between NEA member countries with mature nuclear power plants and newcomers was quite important since it gave newcomers the possibility to benefit of mature international practices in order to focus their regulatory oversight and control. NEA members could also benefit from insights the New Entrants discover as they develop or enhance their regulatory controls. In addition technical exchanges associated with construction experience of New Entrants as they begin to license, build and operate NPP could benefit NEA members

    Some say that an increase in security does not necessarily mean a further encroachment on privacy - indeed, security is necessary to protect personal data and our privacy. Networks must be secure, our personal devices, reliable, dependable and trustworthy. But security is a multifaceted term, with many dimensions. We are of the view that an increase in security most likely will encroach upon our privacy in an ambient intelligence world. Surveillance cameras will continue to proliferate. We assume that, whatever the law is, whatever privacy protections government and business say they honour, our telecommunications, e-mails and Internet usage will be monitored to an increasing degree. The same will be true of our interfaces with the world of ambient intelligence.

    Full Text Available Bombus terrestris, commonly known as the buff-tailed bumblebee, is native to Europe, parts of Africa and Asia. It is commercially bred for use as a pollinator of greenhouse crops. Larvae pupate within a silken cocoon that they construct from proteins produced in modified salivary glands. The amino acid composition and protein structure of hand drawn B. terrestris, silk fibres was investigated through the use of micro-Raman spectroscopy. Spectra were obtained from single fibres drawn from the larvae salivary gland at a rate of 0.14 cm/s. Raman spectroscopy enabled the identification of poly(alanine, poly(alanine-glycine, phenylalanine, tryptophan, and methionine, which is consistent with the results of amino acid analysis. The dominant protein conformation was found to be coiled coil (73% while the β-sheet content of 10% is, as expected, lower than those reported for hornets and ants. Polarized Raman spectra revealed that the coiled coils were highly aligned along the fibre axis while the β-sheet and random coil components had their peptide carbonyl groups roughly perpendicular to the fibre axis. The protein orientation distribution is compared to those of other natural and recombinant silks. A structural model for the B. terrestris silk fibre is proposed based on these results.

    Very low density polyethylene (VLDPE) films were prepared by quenching the pressed melt in ice water. The films were drawn with universal testing machine under constant temperature at four different temperatures, 30, 60, 80, and 110 {sup o} C. Thermal, mechanical properties, grossity, and gas permeability of the drawn VLDPE films as a function of draw ratio were investigated to examine their applicability to packaging. The films showed tow melting peaks, i.e., low temperature endotherm (LTE) and high temperature endotherm (HTE). The melting temperatures were increased with the draw ratio and the drawing temperature. The mechanical properties of the VLDPE film drawn at 80 {sup o} C were superior to those drawn at 110 {sup o} C. The grossity and gas permeability of the VLDPE film drawn at 110 {sup o} C were found to be best among the drawn films.

Impairments on decision-making tasks are routinely reported: evidence points to a particular deficit in learning from and revising behavior following feedback. In addition, patients tend to make hasty decisions when probabilistic judgments are required. This is known as “jumping to conclusions” (JTC and has typically been demonstrated by presenting participants with colored beads drawn from one of two “urns” until they claim to be sure which urn the beads are being drawn from (the proportions of colors vary in each urn. Patients tend to make early decisions on this task, and there is evidence to suggest that a hasty decision-making style might be linked to delusion formation and thus be of clinical relevance. Various accounts have been proposed regarding what underlies this behavior. In this review, we briefly introduce the disorder and the decision-making deficits associated with it. We then explore the evidence for each account of JTC in the context of a wider decision-making deficit and then go on to summarize work exploring JTC in healthy controls using pharmacological manipulations and functional imaging. Finally, we assess whether JTC might have a role in therapy.Keywords: ketamine, decision making, delusions, fMRI, urn task

  14. Physician-assisted dying: thoughts drawn from Albert Camus' writing.

    2018-03-20

    Physician-assisted dying (assisted suicide and euthanasia) is currently an intensely discussed topic in several countries. Despite differences in legislation and application, countries with end-of-life laws have similar eligibility criteria for assistance in dying: individuals must be in a hopeless situation and experience unbearable suffering. Hopelessness, as a basic aspect of the human condition, is a central topic in Albert Camus' philosophical work The Myth of Sisyphus, which addresses the question of suicide. Suffering in the face of a hopeless situation, and the way doctors approach this suffering, is the topic of his novel The Plague, which describes the story of a city confronted with a plague epidemic. In this paper, I draw philosophical and ethical conclusions about physician-assisted dying based on an analysis of central concepts in the work of Camus-specifically, those treated in The Myth of Sisyphus and The Plague. On the basis of my interpretation of Camus' work, I argue that hopelessness and unbearable suffering are useless as eligibility criteria for physician-assisted dying, given that they do not sufficiently elucidate where the line should be drawn between patients who should to be eligible for assistance and those who should not.

    The horizontal land was made by burying the valley made by abandoned mine with waste rocks in Okawa Village in Kochi prefecture, and hydroponic cultivation was carried out. Possibility of use of air flow heat energy using the mine ventilation in order to economize and save energy of this cultivation was studied. If continuous green house ventilation is carried using air drawn from tunnel, applicable house temperature and humidity for certain scale of green house was possible to control within constant limit. When warming of 4 green houses from November to April was carried out, the maximum power load, the heating load for January, was 1,746.43kW and ventilation rate was 5.51 times/hour. Consumption for February was higher than January because of decrease of airflow drawn energy inside the tunnel. As for cooling from July to September, for August as the hottest month, maximum consumed energy required to maintain green house temperature was 2,058.28kW, and demand of airflow rate drawn inside the tunnel was 128.38m[sup 3]/s. 7 refs., 7 figs., 5 tabs.

    Pencil traces drawn on print papers are shown to function as strain gauges and chemiresistors. Regular graphite/clay pencils can leave traces composed of percolated networks of fine graphite powders, which exhibit reversible resistance changes upon compressive or tensile deflections. Flexible toy pencils can leave traces that are essentially thin films of graphite/polymer composites, which show reversible changes in resistance upon exposure to volatile organic compounds due to absorption/desorption induced swelling/recovery of the polymer binders. Pencil-on-paper devices are low-cost, extremely simple and rapid to fabricate. They are light, flexible, portable, disposable, and do not generate potentially negative environmental impact during processing and device fabrication. One can envision many other types of pencil drawn paper electronic devices that can take on a great variety of form factors. Hand drawn devices could be useful in resource-limited or emergency situations. They could also lead to new applications integrating art and electronics.

  6. Human motion retrieval from hand-drawn sketch.

    The rapid growth of motion capture data increases the importance of motion retrieval. The majority of the existing motion retrieval approaches are based on a labor-intensive step in which the user browses and selects a desired query motion clip from the large motion clip database. In this work, a novel sketching interface for defining the query is presented. This simple approach allows users to define the required motion by sketching several motion strokes over a drawn character, which requires less effort and extends the users’ expressiveness. To support the real-time interface, a specialized encoding of the motions and the hand-drawn query is required. Here, we introduce a novel hierarchical encoding scheme based on a set of orthonormal spherical harmonic (SH) basis functions, which provides a compact representation, and avoids the CPU/processing intensive stage of temporal alignment used by previous solutions. Experimental results show that the proposed approach can well retrieve the motions, and is capable of retrieve logically and numerically similar motions, which is superior to previous approaches. The user study shows that the proposed system can be a useful tool to input motion query if the users are familiar with it. Finally, an application of generating a 3D animation from a hand-drawn comics strip is demonstrated.

  7. Online Signature Verification on MOBISIG Finger-Drawn Signature Corpus

    Full Text Available We present MOBISIG, a pseudosignature dataset containing finger-drawn signatures from 83 users captured with a capacitive touchscreen-based mobile device. The database was captured in three sessions resulting in 45 genuine signatures and 20 skilled forgeries for each user. The database was evaluated by two state-of-the-art methods: a function-based system using local features and a feature-based system using global features. Two types of equal error rate computations are performed: one using a global threshold and the other using user-specific thresholds. The lowest equal error rate was 0.01% against random forgeries and 5.81% against skilled forgeries using user-specific thresholds that were computed a posteriori. However, these equal error rates were significantly raised to 1.68% (random forgeries case and 14.31% (skilled forgeries case using global thresholds. The same evaluation protocol was performed on the DooDB publicly available dataset. Besides verification performance evaluations conducted on the two finger-drawn datasets, we evaluated the quality of the samples and the users of the two datasets using basic quality measures. The results show that finger-drawn signatures can be used by biometric systems with reasonable accuracy.

    One of the major considerations in the current deep drawing practice is the product quality. In this research, the effect of heating temperature on the drawability of the round metal cup has been investigated. Firstly, round metal cups of aluminium and mild steel were drawn from the blank diameters of 60 mm, 65 mm and 70 mm. The experiment conducted at room temperature first, then at 50°C and 100°C. The elongation of the major and minor strains along the cup profile after the process is measured and analysed. On the other hand, the defects from the experiment output and ABAQUS/CAE simulation are compared. The result from experiment shows that the highest major elongation is 11.64 mm and it is happened to a deep drawn aluminium round cup with LDR of 1.69 at temperature of 100°C. On the other hand, for deep drawn mild steel round cup, shows highest major elongation of 12.44 mm for a cup with LDR of 1.56 at 100°C. Both of these statements indicates that the higher temperature could improve the formability of the deep drawn parts besides reducing the probability of the defect to be happened.

    1986-02-01

    The conclusions and recommendations formulated for the global program by the 8th meeting of the Expanded Program on Immunization (EPI) Global Advisory Group, which took place during November 1985, are summarized. The Global Advisory Group recommends that, in furtherance of the Five-Point Action Program endorsed by the World Health Assembly in 1983, 3 general and 4 specific actions be taken by national immunization programs with the support of the World Health Organization (WHO) to accelerate EPI progress. These recommendations reflect optimism that the 1990 goal of reducing morbidity and mortality by providing immunization for all children of the world can be realized but also acknowledge that many fundamental problems of national program management remain to be resolved. The general actions are: to promote the achievement of the 1990 immunization goal at national and international levels through collaboration among ministries, organizations, and individuals in both the public and private sectors; to adopt a mix of complementary strategies for program acceleration; and to ensure that rapid increases in coverage can be sustained through mechanisms which strengthen th delivery of other primary health care interventions. The specific actions are as follows: to provide immunization at every contact point; to reduce dropout rates between 1st and last immunizations; to improve immunization services to the disadvantaged in urban areas; and to increase priority for the control of measles, poliomyelitis, and neonatal tetanus. The WHO and the UN International Children's Emergency Fund (UNICEF) have collaborated in support of the EPI since the early days of the program. The acceleration of national efforts heightens the importance of this collaboration, particularly at the national level. It may be further facilitated by the provision of policy guidance from global and regional levels, by WHO and UNICEF collaborative agreements at the regional level, and by country agreements

  11. Low temperature annealing of cold-drawn pearlitic steel wire

    DEFF Research Database (Denmark)

    Zhang, Xiaodan; Bech, Jakob Ilsted; Hansen, Niels

    2015-01-01

    Cold-drawn pearlitic steel wires are nanostructured and the flow stress at room temperature can reach values above 6 GPa. A typical characteristic of the nanostructured metals, is the low ductility and thermal stability. In order to optimize both the processing and application of the wires......, the thermal behaviour is of interest. This has been studied by annealing the wires for 1h at temperatures from ambient temperature to 300 ℃ (573 K). It is expected that a raising temperature may lead to structural changes and a reduction in strength. The change in strength is however not expected to be large....... For this reason we have applied a very precise technique to measure the tensile properties of the wires from a strain of 10-4 to the maximum strain of about 1-2%. The structural changes have also been followed to estimate and relate strength changes to changes in structural parameters and morphology....

    The considerable advances made in nuclear technology in recent years have brought with them a sizeable accumulation of nuclear waste. Leaving aside the low-activity wastes which are stored at ground level, the problem of high-activity wastes still remains. A concerted research effort has been dedicated to perfecting certain methods for waste disposal. At present, this effort has been directed towards evaluating feasibility and the long-term safety of burying these wastes in deep-lying and stable geological repositories. A priori, many types of rocks are suitable for isolating nuclear wastes: clay, salt, granite, schists, basalt and tuff. These wastes are exothermic owing to their radioactive decay which decreases continuously with time. From the geotechnical point of view, storage of these high-activity wastes in a deep-lying geological environment will increase temperature in the host rock accompanied by changes in stresses and strains. Quantifying these changes, by means of a thermomechanical analysis, is of prime importance when the mechanical behaviour of the storage drifts has to be ensured by avoiding major modifications to the characteristics of the geological barrier. This article summarises the present state of knowledge acquired about the thermomechanical behaviour of granite, and presents the results as research requirements for better characterisation in the laboratory and in situ as well as a more realistic model. We also stress the results of research carried out by the Centre de Geotechnique et d'Exploitation du sous-sol (CGES) of the Ecole des Mines de Paris (ENSMP) on the Fanay-Augeres Thermal, Hydraulic and Mechanical experiment organised by the Institut de Protection et de Surete Nucleaire (IPSN) in the context of a shared-costs contract with the Commission of the European Communities (CEC).

  13. Efficiency of blue-green stormwater retrofits for flood mitigation - Conclusions drawn from a case study in Malmö, Sweden.

    Coupled one-dimensional (1D) sewer and two-dimensional (2D) overland flow hydrodynamic models were constructed to evaluate the flood mitigation efficiency of a renowned blue-green stormwater retrofit, i.e. Augustenborg, in Malmö, Sweden. Simulation results showed that the blue-green stormwater systems were effective in controlling local surface flooding in inner-city catchments, having reduced the total flooded surfaces by about 70%. However, basement flooding could still be a potential problem depending on the magnitude of the inflows through combined sewer from upstream areas. Moreover, interactions between blue-green retrofits and the surrounding pipe-system were studied. It was observed that the blue-green retrofits reduced the peak flows by approximately 80% and levelled out the runoff. This is a substantial advantage for downstream pipe-bound catchments, as they do not receive a cloudburst-equivalent runoff from the retrofitted catchment, but a reduced flow corresponding to a much milder rainfall. Blue-green retrofits are more effective if primarily implemented in the upstream areas of a pipe-bound catchment since the resulting reduced runoff and levelled out discharge would benefit the entire network lying downstream. Implementing blue-green retrofits from upstream towards downstream can be considered as a sustainable approach. Copyright © 2017 Elsevier Ltd. All rights reserved.

    A special determination method allowed to confirm the transferability of fracture mechanics parameters for crack initiation. A correlation was found between notch impact energy and crack initiation value for the higher shelf of toughness. Carrying and deformation behaviour of components can be determined when stress condition and multi-axis degree are known. The onset of stable and cyclical crack expansion can be verfied by sound emission techniques under corrosive conditions, too. The operational influence of corrosion and radiation can be quantified for specific conditions and states. (DG) [de

  15. Poling effects on anisotropic temperature changes in NMR second moments of drawn PVDF films

    International Nuclear Information System (INIS)

    Ishii, Fumiaki; Sawatari, Takanori; Odajima, Akira

    1982-01-01

    For the drawn PVDF film, the NMR second moment vs temperature curves at 0 0 and 90 0 of the alignment angle (γ) cross over each other during the motional narrowing in the Tsub(g) region (-- -50 0 C). On poling, however, they decrease almost in parallel up to -20 0 C and show another narrowing above 30 0 C depending strongly on γ. These findings indicate that the molecular chain is oriented in the non-crystalline region and the poling more clearly separates low orientations from high orientations. The increase in the high orientation part should be attributed to polarization in the oriented non-crystalline region. (author)

  16. TEST OF AN ANIMAL DRAWN FIELD IMPLEMENT CART

    Directory of Open Access Journals (Sweden)

    Paolo Spugnoli

    2008-06-01

    Full Text Available The field performance of a horse-drawn hitch cart equipped with a PTO system powered by the two cart ground wheels have been investigated. For this purpose field tests on clay and turf soil, with varying ballast and PTO torque, have been carried out pulling the cart by a tractor. Preliminary tests were aimed at assessing the traction capability of horse breed. These tests showed that the mean draught force given by two of these horses was 173daN, average working speed was about 1m*s-1, resulting a mean draught power developed by each horse of about 0.86kW. The PTO cart system performance has shown that the torque has not exceeded 2.4daN*m, maximum draught or PTO power was 1.15kW, rotation speed just higher than 400min-1, with mean efficiency of about 50%. These values are consistent with horse performance and small haymaking, fertilizing, seeding and chemical application machine requirements.

  18. Only one simple conclusion about the climate

    Energy Technology Data Exchange (ETDEWEB)

    Jaremko, G.

    2000-07-24

    Findings concerning climate change, by a three-man team of scientists from the North Dakota Geological Survey, which were presented in a paper read at the Eight International Williston Basin Horizontal Well Workshop, are discussed. The survey by the three scientists covered more than 6,000 scholarly publications. It reported that while the rise in the Earth's temperature is beyond argument, there is anything but agreement as to the causes, or whether the trend is unusual enough to justify concerted and costly actions to change lifestyles. It is shown by direct instrumental measurements that the average temperature at the Earth's surface increased about 0.8 degree Celsius between 1866 and 1998. During that time the concentration of carbon dioxide in the atmosphere increased from 280 to 353 parts per million. While it is generally assumed that the global warming was caused by human activities, new techniques of measurement such as glacier ice coring, dendrochronology (tree-growth rings), lichenometry (measuring the diameter of lichens) and counting concentrations of oxygen 18 and 16 (isotopes whose presence in marine fossils varies depending on temperature) suggest that most of the global warming took place before the increase in carbon dioxide concentration occurred, raising the possibility that the increase in average temperature had causes other than the increase in greenhouse gases. Some of the studies reviewed by the group show that in Europe between ice ages during the Eemian period, some 135,000 to 110,000 years ago, temperature variations of seven degrees Celsius took place; they dropped from two degree Celsius warmer than today to five degree Celsius colder than today. Based on these findings the group's only firm conclusion was that climate is in a continual flux.

    2013-01-01

    In this present investigation, the mechanical properties of industrial drawn copper wires have been studied by tensile tests. The effect of prior heat treatments at 500°C on the drawn wires behavior was the main goal of this investigation. We have found that the mechanical behavior of drawn wires depends strongly on those treatments. SEM observations of the wire cross section after tensile tests have shown that the mechanism of rupture was mainly controlled by the void formation

    to two orders of magnitude because of strainer clogging. Consequently, the CSNI decided to continue its previous efforts in the area. The overall purpose of the 2004 Workshop was to discuss the impact of new information made available since 1996 and to promote consensus among member countries on identification of remaining technical issues important to safety, and on possible paths for their resolution. The specific purposes of the Workshop were: a. To review the knowledge base and in particular information developed after 1999, and to consider the validity of the conclusions drawn. b. To exchange information on the current status of research related to debris generation, debris transportation, and sump strainer clogging and penetration phenomena, in particular for PWRs, and to assess uncertainties. c. To exchange and disseminate information on recent and current activities and practices in these areas. d. To identify and discuss differences between approaches relevant to reactor safety. e. To identify technical issues and programs of interest for international collaborative research and develop an Action Plan outlining activities that CSNI should undertake in the area of strainer or sump screen clogging during the next few years. Summary of the main findings: a. The safety significance of the sump strainer clogging depends on the plant design (e.g. sump strainer, ECCS) and backfitting measures performed. b. The following are examples of PWR design features that could influence the debris impact on the ECCS sump performance: - Type of insulation (material, combination of materials, protection). - Break size to be postulated. - Transport in containment with or without containment spray system (CSS). - Degree of turbulence and flow velocities in the sump influenced by CSS, water level, break flow location and sump geometry. - Redundancy of sumps and residual heat removal system (RHRS). - Strainer design (area, mesh size). - Positioning of recirculation pumps and vortex

    Strain softening effects have been previously observed in drawn low carbon steel bars as a result of cyclic torsion experiments. In this paper, the substructural aspects related to the phenomenon have been investigated. Single pass drawn bars were subjected to a quarter, to a half, to a full torsion cycle and to 10 such cycles. Transmission electron microscopy revealed the development of extended microbands crossing the former dislocation arrangement of the drawn metal, which evolves to a rectangular shaped subgrains structure as torsion deformation is conducted

    1977-01-01

    In the GDR all unusual events in the field of ionizing radiation have been recorded and analysed since 1963. This is done by a central governmental institution, the National Board of Nuclear Safety and Radiation Protection established in 1962, and responsible for all relevant measures throughout the country. An unusual event is defined by radiation protection legislation as an event which deviates from the planned operation programme whether the incident has caused injury or not. The obligation to report such events rests on all licensed users, from users of X-ray machines to operators of reactors in research and nuclear power production. The listed events are continually assessed by the Board. The results of the assessment are evaluated in summary. There has not been a single event with a fatal outcome arising from ionizing radiation. Over the same period there were only seventeen occurrences which resulted in permanent injury to persons, mainly effected by acute external irradiation of parts of the body, especially of hands and forearms. Among the detected causes of unusual events described in detail, human failure predominates by far. Finally, conclusions are drawn from these results. The measures suggested all aim to reduce the frequency of radiation accidents and to minimize their consequences. The main measures concern ways of reducing human error in all fields of radiation protection. Among these, the education and training and the medical examination of radiation workers are discussed in somewhat more detail. (author)

    Highlights: • Estimation of research priorities related to severe accident phenomena. • Consideration of new topics, partly linked to the severe accidents at Fukushima. • Consideration of results of recent projects, e.g. SARNET, ASAMPSA2, OECD projects. - Abstract: The objectives of the SARNET network of excellence are to define and work on common research programs in the field of severe accidents in Gen. II–III nuclear power plants and to further develop common tools and methodologies for safety assessment in this area. In order to ensure that the research conducted on severe accidents is efficient and well-focused, it is necessary to periodically evaluate and rank the priorities of research. This was done at the end of 2008 by the Severe Accident Research Priority (SARP) group at the end of the SARNET project of the 6th Framework Programme of European Commission (FP6). This group has updated this work in the FP7 SARNET2 project by accounting for the recent experimental results, the remaining safety issues as e.g. highlighted by Level 2 PSA national studies and the results of the recent ASAMPSA2 FP7 project. These evaluation activities were conducted in close relation with the work performed under the auspices of international organizations like OECD or IAEA. The Fukushima-Daiichi severe accidents, which occurred while SARNET2 was running, had some effects on the prioritization and definition of new research topics. Although significant progress has been gained and simulation models (e.g. the ASTEC integral code, jointly developed by IRSN and GRS) were improved, leading to an increased confidence in the predictive capabilities for assessing the success potential of countermeasures and/or mitigation measures, most of the selected research topics in 2008 are still of high priority. But the Fukushima-Daiichi accidents underlined that research efforts had to focus still more to improve severe accident management efficiency

    In ecology, expert knowledge on habitat characteristics is often used to define sampling units such as study sites. Ecologists are especially prone to such approaches when prior sampling frames are not accessible. Here we ask to what extent can different approaches to the definition of sampling units influence the conclusions that are drawn from an ecological study? We do this by comparing a formal versus a subjective definition of sampling units within a study design which is ...

  17. Effects of γ-irradiation and thermal treatment of crystallinity of drawn HDPE

    International Nuclear Information System (INIS)

    Liu Zhanjun; Silverman, J.

    1997-01-01

    The effect of absorbed dose irradiated in vacuum and air on the crystallinity of drawn HDPE was studied. Experimental results show that up to 250 kGy of absorbed dose when irradiated in vacuum, the crystallinity of drawn HDPE is decreased from about 75% to about 71%, and then the increase of absorbed dose until 1000 kGy has no further effect in lowering the crystallinity; when irradiated in air, an absorbed dose of 1000 kGy has no effect on the crystallinity of drawn HDPE. The effect of temperature of thermal treatment on the crystallinity of unirradiated drawn HDPE was also investigated. At first, the crystallinity is increased with the increase of temperature of thermal treatment, at about 120 degree C, it reaches the maximum value, and then it is rapidly lowered with the further increase of temperature of thermal treatment. Based on the existence of a lot of voids and lattice defects inside the drawn HDPE, the above experimental results were explained

    Microstructural (X-ray diffraction), magnetic properties (hysteresis loop), electrical resistivity, magneto-impedance and stress impedance effects have been investigated in cold-drawn Fe 77.5 B 15 Si 7.5 amorphous wire. Initial amorphous wire (obtained by the in-rotating-water technique) with diameter of 125 μm was submitted to cold-drawn process decreasing the diameter to 50 μm. Such cold-drawn wire was treated by current annealing (currents of 190, 210, 220 and 230 mA during times between 1 and 45 min) for tailoring the magnetic and electrical transport properties.

    Results on local hysteresis loops for Fe-rich amorphous cold-drawn wires with the sample lengths of 30 mm and 70 mm under applied stress, σ, up to 1300 MPa are reported. For both lengths, the magnetization, M, increases with σ and the coercive field, H C , decreases. Near the wire end, M results to be larger than at the wire center, and H C sharply decreases. This reduction is eliminated if the applied stress is large enough. It is assumed, that the magnetic configuration at the wire end for the cold-drawn wires is different from the other wires families

    target styles. (2) Brush-style transfer, on the other hand, focuses on transferring a unique brush look of a line drawing to the input sketch. In this transfer stage, we use an automatically constructed input brush dictionary to infer which sparse set of input brush elements are used at each location of the input sketch. Then, a one-to-one mapping between input and target brush elements is learned by sparsely encoding the target sketch with the input brush dictionary. The last part of the dissertation targets a geometric representation of sketches, which is vital in enabling automatic sketch analysis, synthesis and manipulation. It is based on utilizing the well known convolutional sparse coding (CSC) model. We observe that CSC is closely related to how line sketches are drawn. This process can be approximated as the sparse spatial localization of a number of typical basic strokes, which in turn can be cast as a non-standard CSC model that forms a line drawing from parametric curves. These curves are learned to optimize the fit between the model and a specific set of line drawings. Each part of the dissertation shows the utility of the proposed methods through a variety of experiments, user studies, and proposed applications.

    Highlights: Black-Right-Pointing-Pointer Annealing time on microstructure and mechanical properties of cold-drawn steel wires were studied. Black-Right-Pointing-Pointer Exothermic peak in cold-drawn wire was resulting from the spheroidization of lamellar cementite. Black-Right-Pointing-Pointer Spheroidization of lamellar cementite is the main effect for torsion property of wires after annealing. - Abstract: Spheroidization of lamellar cementite often occurs in cold-drawn pearlitic steel wires during galvanizing treatment, leading to the degradation of mechanical properties. Therefore, it is important to understand effects of galvanization process on microstructure and mechanical properties of cold-drawn wires. In this paper, cold-drawn steel wires were fabricated by cold drawing pearlitic steel rods from 13 mm to 6.9 mm in diameter. Thermal annealing at 450 Degree-Sign C was used to simulate galvanizing treatment of steel wires. Tensile strength, elongation and torsion laps of steel rods and wires with, and without, annealing treatment were determined. Microstructure was observed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). In addition, differential scanning calorimetry (DSC) was used to probe the spheroidization temperature of cementite. Experimental results showed that tensile strength of wires increased from 1780 MPa to 1940 MPa for annealing <5 min, and then decreased. Tensile strength became constant for annealing >10 min. Elongation of wires decreased for annealing <2.5 min, and then recovered slightly. It approached a constant value for annealing >5 min. Tensile strength and elongation of wires were both influenced by the strain age hardening and static recovery processes. Notably, torsion laps of wires hardly changed when annealing time was less than 2.5 min, and then decreased rapidly. Its value became constant when the hold time is greater than 10 min. Lamellar cementite began to spheroidize at annealing >2.5 min

  11. The Danish energy crop research and development project - main conclusions

    Production of energy crops in Denmark is more or less non-existent in Denmark at the time being. However, the need for biomass on the other side of year 2005 exceeds the existing biomass resources and a substantial amount of energy crops will be necessary in order to fulfil the goals in Energy 21. The targeted share of the use of renewable energy sources by year 2030 is approximately 30%. Energy crops are seen as the most important new resource in order to create a balanced input mix of renewable in the energy system. The energy crops are mainly seen as fuel in small and medium sized CHP plants and in the big power plants. The Danish energy crop project consists of three main parts: a demonstration part, a research and development part, and an overall assessment part. Based on the results from the project the following overall conclusions can be made: Seen from a strictly market and production economic point of view energy crops will not be competitive in a foreseeable future, neither as a production for farmers nor as a fuel at the utility companies; The costs per GJ of energy crops are still higher than a GJ of straw; The cost difference between annual and perennial energy crops are slightly in favour of perennials, however the conditions on the individual farms should govern the choice between annual and perennial energy crops; Energy crops must be seen as part of an overall environmental scheme covering both agriculture and the energy sector; Given the right production scheme energy crops can be grown on environmental sensitive areas and on most ground water protection areas; Adding the potential sustainability benefits like reduced nutrient leakage and reduced CO 2 emissions energy crops seem to be a sensible and sustainable solution; Due to different handling, storage and fuel characteristics an all year delivery scheme of energy crops should include a mix of different energy crops to keep overall cost down.

    A flexible and disposable paper-based pH sensor fabricated with a pencil-drawn working electrode and a Ag/AgCl paste reference electrode is demonstrated for the first time to show pH response by the potentiometric principle. The sensor substrate is made of chromatography paper with a wax-printed hydrophobic area, and various types of carbon pencils are tested as working electrodes. The pH sensitivities of the electrodes drawn by carbon pencils with different hardnesses range from 16.5 to 26.9 mV/pH. The proposed sensor is expected to be more robust against shape change in electrodes on a flexible substrate than other types of chemiresistive/amperometric pH sensors.

    The texture of the cold-drawn copper wire was investigated along the radius using electron backscatter diffraction. The complex fiber texture of the central region of the wire was considered as the rolling texture consisting of a set of preferred orientations. The texture of the periphery region was revealed to be similar to the shear texture. The orientation-dependent properties of the wire were proven to be determined by the texture of the near-surface layers.

    Degassing effects of ultrasonic and vacuum processes on high conductivity hard drawn aluminum melt were studied. Results showed that the degassing efficiency improved with the increase of ultrasonic power within certain range, stabilizing at 70% with 240W. For vacuum degassing process, hydrogen content of aluminum melt decreased with the loading time and was linear with logarithm of vacuum degree. Comparison of degassing effects of ultrasonic, vacuum, vacuum-ultrasonic degassing process showed that vacuum-ultrasonic process presented optimal effect.

    2014-07-01

    Dealing with difference is central to all couple therapy. This article presents an intervention designed to assist couples in handling conflict. Central to this approach is the acceptance that most conflicts cannot be solved. Couples are in need of a different understanding of couples conflict. This understanding is found in the analysis of love in context and in relational dialectics. Couples are guided through different steps: deciding on the valence of the issue as individuals, helping them decide which differences can be resolved and which issues demand new ways of living with the inevitable, and the introduction in the suggested no conclusion dialogue. This article briefly describes the five day intensive couple therapy program, in which the no intervention is embedded. The theoretical foundation of the intervention, followed by the step by step description of the intervention forms the major part of the article. A case vignette illustrates this approach. © 2012 American Association for Marriage and Family Therapy.

    Full Text Available Our brains readily decode facial movements and changes in social attention, reflected in earlier and larger N170 event-related potentials (ERPs to viewing gaze aversions vs. direct gaze in real faces (Puce et al. 2000. In contrast, gaze aversions in line-drawn faces do not produce these N170 differences (Rossi et al., 2014, suggesting that physical stimulus properties or experimental context may drive these effects. Here we investigated the role of stimulus-induced context on neurophysiological responses to dynamic gaze. Sixteen healthy adults viewed line-drawn and real faces, with dynamic eye aversion and direct gaze transitions, and control stimuli (scrambled arrays and checkerboards while continuous electroencephalographic (EEG activity was recorded. EEG data from 2 temporo-occipital clusters of 9 electrodes in each hemisphere where N170 activity is known to be maximal were selected for analysis. N170 peak amplitude and latency, and temporal dynamics from event-related spectral perturbations (ERSPs were measured in 16 healthy subjects. Real faces generated larger N170s for averted vs. direct gaze motion, however, N170s to real and direct gaze were as large as those to respective controls. N170 amplitude did not differ across line-drawn gaze changes. Overall, bilateral mean gamma power changes for faces relative to control stimuli occurred between 150-350 ms, potentially reflecting signal detection of facial motion.Our data indicate that experimental context does not drive N170 differences to viewed gaze changes. Low-level stimulus properties, such as the high sclera/iris contrast change in real eyes likely drive the N170 changes to viewed aversive movements.

    Anaphylaxis is a life-threatening event. Most clinical symptoms of anaphylaxis can be reversed by prompt intramuscular administration of epinephrine using an auto-injector or epinephrine drawn up in a syringe and delays and errors may be fatal. The aim of this scoping review is to identify and compare errors associated with use of epinephrine drawn up in a syringe versus epinephrine auto-injectors in order to assist hospitals as they choose which approach minimizes risk of adverse events for their patients. PubMed, Embase, CINAHL, Web of Science, and the Cochrane Library were searched using terms agreed to a priori. We reviewed human and simulation studies reporting errors associated with the use of epinephrine in anaphylaxis. There were multiple screening stages with evolving feedback. Each study was independently assessed by two reviewers for eligibility. Data were extracted using an instrument modeled from the Zaza et al instrument and grouped into themes. Three main themes were noted: 1) ergonomics, 2) dosing errors, and 3) errors due to route of administration. Significant knowledge gaps in the operation of epinephrine auto-injectors among healthcare providers, patients, and caregivers were identified. For epinephrine in a syringe, there were more frequent reports of incorrect dosing and erroneous IV administration with associated adverse cardiac events. For the epinephrine auto-injector, unintentional administration to the digit was an error reported on multiple occasions. This scoping review highlights knowledge gaps and a diverse set of errors regardless of the approach to epinephrine preparation during management of anaphylaxis. There are more potentially life-threatening errors reported for epinephrine drawn up in a syringe than with the auto-injectors. The impact of these knowledge gaps and potentially fatal errors on patient outcomes, cost, and quality of care is worthy of further investigation.

  2. Water is a poor solvent for densely grafted poly(ethylene oxide) chains: a conclusion drawn from a self-consistent field theory-based analysis of neutron reflectivity and surface pressure-area isotherm data.

    By use of a combined experimental and theoretical approach, a model poly(ethylene oxide) (PEO) brush system, prepared by spreading a poly(ethylene oxide)-poly(n-butyl acrylate) (PEO-PnBA) amphiphilic diblock copolymer onto an air-water interface, was investigated. The polymer segment density profiles of the PEO brush in the direction normal to the air-water interface under various grafting density conditions were determined by using the neutron reflectivity (NR) measurement technique. To achieve a theoretically sound analysis of the reflectivity data, we used a data analysis method that utilizes the self-consistent field (SCF) theoretical modeling as a tool for predicting expected reflectivity results for comparison with the experimental data. Using this data analysis technique, we discovered that the effective Flory-Huggins interaction parameter of the PEO brush chains is significantly greater than that corresponding to the θ condition in Flory-Huggins solutions (i.e., χ(PEO-water)(brush chains)/χ(PEO-water)(θ condition) ≈ 1.2), suggesting that contrary to what is more commonly observed for PEO in normal situations (χ(PEO-water)(free chains)/χ(PEO-water)(θ condition) ≈ 0.92), the PEO chains are actually not "hydrophilic" when they exist as polymer brush chains, because of the many body interactions that are forced to be effective in the brush situation. This result is further supported by the fact that the surface pressures of the PEO brush calculated on the basis of the measured χ(PEO-water) value are in close agreement with the experimental surface pressure-area isotherm data. The SCF theoretical analysis of the surface pressure behavior of the PEO brush also suggests that even though the grafted PEO chains experience a poor solvent environment, the PEO brush layer exhibits positive surface pressures, because the hydrophobicity of the PEO brush chains (which favors compression) is insufficient to overcome the opposing effect of the chain conformational entropy (which resists compression).

  3. Tensile behaviour of drawn tungsten wire used in tungsten fibre-reinforced tungsten composites

    In tungsten fibre-reinforced tungsten composites (W f /W) the brittleness problem of tungsten is solved by utilizing extrinsic toughening mechanisms. The properties of the composite are very much related to the properties of the drawn tungsten wire used as fibre reinforcements. Its high strength and capability of ductile deformation are ideal properties facilitating toughening of W f /W. Tensile tests have been used for determining mechanical properties and study the deformation and the fracture behaviour of the wire. Tests of as-fabricated and straightened drawn wires with a diameter between 16 and 150 μ m as well as wire electrochemically thinned to a diameter of 5 μ m have been performed. Engineering stress–strain curves and a microscopic analysis are presented with the focus on the ultimate strength. All fibres show a comparable stress–strain behaviour comprising necking followed by a ductile fracture. A reduction of the diameter by drawing leads to an increase of strength up to 4500 MPa as a consequence of a grain boundary hardening mechanism. Heat treatment during straightening decreases the strength whereas electrochemical thinning has no significant impact on the mechanical behaviour. (paper)

    2000-01-01

    The action program Energy 2000 has been continually reviewed by independent experts in view of its effects. This resulted in around 50 scientific studies between 1991 and 1999, dealing with different aspects of the program. In the book 'Energy 2000: effects of the program and conclusions from its evaluation', the results of these evaluations are summarised, and conclusions for the design of the follow-up program are drawn. The organisational frame of the program is presented and the question answered whether the determining principles of the program proved practical. Besides, the effects of state intervention, of the conflict solving groups and the voluntary actions of Energy 2000 are appraised. A separate chapter is dedicated to the evaluation strategy of the program, its implementation and the benefits of the evaluations. Propositions for the evaluation of the follow-up program are formulated as well. Dr. Andreas Balthasar is President of the Swiss Evaluation Society. (author)

  6. Microstructural evolution and strain hardening behavior of the cold-drawn austenitic stainless steels

    International Nuclear Information System (INIS)

    Choi, Jeom Yong; Jin, Won

    1998-01-01

    The strain induced α ' -martensite formation and the strain hardening behavior of metastable austenitic stainless steel during cold drawing have been investigated. The strain induced α ' -martensite nucleates mainly at the intersection of the mechanical twins rather than ε-martensite. It could be explained by the increase of stacking fault energy which arises from the heat generated during high speed drawing and, for AISI 304/Cu, the additional effect of Cu additions. The strain hardening behavior of austenitic stainless steel is strongly related to the microstructural evolution accompanied by strain induced α ' -martensite. The work hardening rates of cold-drawn 304 increased with increasing interstitial element(C,N) contents which affect the strength of the strain induced α ' -martensite

After reviewing some of the aerial drawings of the mid-19th century, the author considers undocumented hypotheses regarding the relationship of Charles Clifford to the drawings by Guesdon of Spanish cities, and the issues related to their elaboration by means of plans, photographs and hot-air balloons. Some light is shed on this matter thanks to the unpublished drawing of the city of Cordoba (1853, whose accuracy is evident when compared to a city plan drawn by Montis (1851. A journey through the city of Cordoba and its landmarks proves the documentary value of the drawing by Guesdon, who knew how to combine traditional drawing skills with the latest technical advances of his time.

  8. Piezoresistivity of mechanically drawn single-walled carbon nanotube (SWCNT) thin films-: mechanism and optimizing principle

    Obitayo, Waris

    The individual carbon nanotube (CNT) based strain sensors have been found to have excellent piezoresistive properties with a reported gauge factor (GF) of up to 3000. This GF on the other hand, has been shown to be structurally dependent on the nanotubes. In contrast, to individual CNT based strain sensors, the ensemble CNT based strain sensors have very low GFs e.g. for a single walled carbon nanotube (SWCNT) thin film strain sensor, GF is ~1. As a result, studies which are mostly numerical/analytical have revealed the dependence of piezoresistivity on key parameters like concentration, orientation, length and diameter, aspect ratio, energy barrier height and Poisson ratio of polymer matrix. The fundamental understanding of the piezoresistive mechanism in an ensemble CNT based strain sensor still remains unclear, largely due to discrepancies in the outcomes of these numerical studies. Besides, there have been little or no experimental confirmation of these studies. The goal of my PhD is to study the mechanism and the optimizing principle of a SWCNT thin film strain sensor and provide experimental validation of the numerical/analytical investigations. The dependence of the piezoresistivity on key parameters like orientation, network density, bundle diameter (effective tunneling area), and length is studied, and how one can effectively optimize the piezoresistive behavior of a SWCNT thin film strain sensors. To reach this goal, my first research accomplishment involves the study of orientation of SWCNTs and its effect on the piezoresistivity of mechanically drawn SWCNT thin film based piezoresistive sensors. Using polarized Raman spectroscopy analysis and coupled electrical-mechanical test, a quantitative relationship between the strain sensitivity and SWCNT alignment order parameter was established. As compared to randomly oriented SWCNT thin films, the one with draw ratio of 3.2 exhibited ~6x increase on the GF. My second accomplishment involves studying the

  9. Xenon oscillation control in large PWR using a characteristic ellipse trajectory drawn by three axial offsets

    We have proposed a very simple xenon oscillation control procedure based on a characteristic trajectory. The trajectory is drawn by three offsets of power distributions, namely, AOp, AOi and AOx. They are defined as the offset of axial power distribution, the offset of the power distribution under which the current iodine distribution is obtained as the equilibrium and that for xenon distribution, respectively. When these offsets are plotted on X-Y plane for (AOp-AOx, AOi-AOx) the trajectory shows a quite characteristic ellipse (or an elliptic spiral). It shows characteristics such that the center of the ellipse is at the origin, the gradient of the major axis is constant, direction of the trajectory progress is always anti-clock wise, plot goes around the ellipse during a cycle of the xenon oscillation and so on. This characteristic does not change even if the control rods are moved. When the plot is at the origin of the X-Y plane, no xenon oscillation exists. Using the characteristics of the ellipse the xenon oscillation can be eliminated by guiding the plot to the origin with control rod operation. This concept can be applied not only to the axial xenon oscillation but also to the radial xenon oscillation control. Conventionally, the trajectory is drawn based on the xenon dynamics using reactor parameters such as core averaged macroscopic fission cross section, xenon micro absorption cross section, fission yields of iodine and xenon, and so on together with the neutron flux signals. The accuracy is expected to be better. (authors)

  10. Nuclear Energy Center Site Survey, 1975. Part I. Summary and conclusions

    International Nuclear Information System (INIS)

    1976-01-01

    The Nuclear Energy Center Site Survey is a study of a potential siting approach for projected power and fuel-cycle facilities that would cluster sizable groups of such facilities on a relatively small number of sites, as contrasted with current dispersed siting practices. Three basic types of nuclear energy centers (NECs) are considered: power-plant centers, involving ten to forty units of 1200-megawatt electric capacity each; fuel-cycle centers, involving fuel reprocessing plants, mixed-oxide fuel fabrication facilities, and high-level and transuranic radioactive waste management facilities, with a capacity corresponding to the fuel throughput of power plants with a total capacity of approximately 50,000 to 300,000 MWe; and combined centers, containing both power plants and fuel cycle facilities in representative possible combinations. Included among the principal issues considered in evaluation of feasibility of nuclear energy centers are dissipation of the waste heat from the power-generating facilities; transmission system design, reliability, and economics; radiological impact; and environmental impact

  11. Influence of small towns on the lichen vegetation. Part VII. Discussion and general conclusions

    1958-01-01

    The problem of poverty of lichen vegetation in large or industrial towns was raised in 1866. Since then several large European cities have been studied and there were described zones of gradual impoverishment of lichen flora from the outskirts to the centre of the town. The zones are: (1) Zone of normally developed flora at the outskirts of the town. (2) Struggle zone which is a more or less extensive area with scattered houses and which surrounds the crowded central quarters. In this zone scanty specimens of a few lichen species were found; their thalli were contracted, under-developed, as if fighting for life in unfavorable environmental conditions. (3) Lichen-free zone, lichen desert, which comprises the centre of the town and its industrial quarters; no lichens could be found there. The results of these investigations strengthened the belief that lichens are organisms very sensitive to the action of substances formed during coal combustion in town. Sulphur dioxide (SO/sub 2/) was believed to be especially harmful to lichens, causing their death even in trace concentrations.

    Introduction plurihormonality of pituitary adenomas is an ability of adenoma cells to produce more than one hormone. After the immunohistochemical analysis had become a routine part of the morphological study, a great number of adenomas appeared to be multihormonal in actual practice. We hypothesize that the same cells of a normal pituitary gland releases several hormones simultaneously. Objective To analyse a possible co-expression of hormones by the cells of the normal anterior pituitary of adult humans in autopsy material. Materials and methods We studied 10 pituitary glands of 4 women and 6 men with cardiovascular and oncological diseases. Double staining immunohistochemistry using 11 hormone combinations was performed in all the cases. These combinations were: prolactin/thyroid-stimulating hormone (TSH), prolactin/luteinizing hormone (LH), prolactin/follicle-stimulating hormone (FSH), prolactin/adrenocorticotropic hormone (ACTH), growth hormone (GH)/TSH, GH/LH, GH/FSH, GH/ACTH, TSH/LH, TSH/FSH, TSH/ACTH. Laser Confocal Scanning Microscopy with a mixture of primary antibodies was performed in 2 cases. These mixtures were ACTH/prolactin, FSH/prolactin, TSH/prolactin, ACTH/GH, and FSH/GH. Results We found that the same cells of the normal adenohypophysis can co-express prolactin with ACTH, TSH, FSH, LH; GH with ACTH, TSH, FSH, LH, and TSH with ACTH, FSH, LH. The comparison of the average co-expression coefficients of prolactin, GH and TSH with other hormones showed that the TSH co-expression coefficient was significantly the least (9,5±6,9%; 9,6±7,8%; 1,0±1,3% correspondingly). Conclusion Plurihormonality of normal adenohypophysis is an actually existing phenomenon. Identification of different hormones in pituitary adenomas enables to find new ways to improve both diagnostic process and targeted treatment. PMID:28418929

  13. Waste Handling Shaft concrete liner degradation conclusions and recommendations

    International Nuclear Information System (INIS)

    1992-10-01

    The primary function of the Waste Handling Shaft (WHS) at the Waste Isolation Pilot Plant (WIPP) is to permit the transfer of radioactive waste from the surface waste handling building to the underground storage area. It also serves as an intake shaft for small volumes of air during normal storage operations and as an emergency escape route. Part of the construction was the placement of a concrete liner and steel reinforced key in 1984. During a routine shaft inspection in May 1990, some degradation of the WHS concrete liner was observed between the depths of 800 and 900 feet below the ground surface. Detailed investigations of the liner had been carried out by Sandia National Laboratories and by Westinghouse Electric Corporation Waste Isolation Division (WID) through Lankard Materials Laboratory. Observations, reports, and data support the conclusion that the concrete degradation, resulting from attack by chemically aggressive brine, is a localized phenomena. It is the opinion of the WID that the degradation is not considered an immediate or near term concern; this is supported by technical experts. WID recommendations have been made which, when implemented, will ensure an extended liner life. Based on the current assessment of available data and the proposed shaft liner monitoring program described in this report, it is reasonable to assume that the operational life of the concrete shaft liner can safely support the 25-year life of the WIPP. Analysis of data indicates that degradation of the shaft's concrete liner is attributed to chemically aggressive brine seeping through construction joints and shrinkage cracks from behind the liner in and around the 834-foot depth. Chemical and mechanical components of concrete degradation have been identified. Chemical attack is comprised of several stages of concrete alteration. The other component, mechanical degradation, results from the expansive forces of crystals forming in the concrete pore space

    Many investigators consider children's drawings to be an important test in the evaluation of stress and anxiety, but few studies have examined the reliability and validity of indicators of emotional distress in children's projective drawings. In this report, we describe screening tests in children coming to the Friuli Venezia Giulia region in Northeastern Italy from non-European Union regions and suspected to have celiac disease, the problems involved in diagnosis of the disease, and the "drawn double nostalgia" of Romanian children for both Italian food and traditional Romanian foods. Of 3150 Western European cases, we found 712 with positive antibodies for IgA/IgG antitransglutaminase, 174 with a positive antiendomysium antibody confirmation test, and 20 with an IgA deficit. Of the children examined, 93% were children native to Western Europe, 4% were immigrants from Eastern Europe, and 1.6% originated from Africa. Among these, four Romanian children with celiac disease brought in their drawings, as requested in a hospital questionnaire. The prevalence of celiac disease is destined to increase among immigrants. Economic problems are common, and the twin nostalgia of immigrant children for foods and tastes that are "cozonac" (from the native country) and "panettone" (Italian cake flavor) represents a problem that will be difficult to resolve. Only some children's hospitals in Italy, ie, Burlo Garofolo and Gaslini, public and private foundations, or volunteer associations would be able to deal with this problem.

  20. Membrane scaling and flux decline during fertiliser-drawn forward osmosis desalination of brackish groundwater.

    Fertiliser-drawn forward osmosis (FDFO) desalination has been recently studied as one feasible application of forward osmosis (FO) for irrigation. In this study, the potential of membrane scaling in the FDFO process has been investigated during the desalination of brackish groundwater (BGW). While most fertilisers containing monovalent ions did not result in any scaling when used as an FO draw solution (DS), diammonium phosphate (DAP or (NH4)2HPO4) resulted in significant scaling, which contributed to severe flux decline. Membrane autopsy using scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDS), and x-ray diffraction (XRD) analysis indicated that the reverse diffusion of DAP from the DS to the feed solution was primarily responsible for scale formation during the FDFO process. Physical cleaning of the membrane with deionised water at varying crossflow velocities was employed to evaluate the reversibility of membrane scaling and the extent of flux recovery. For the membrane scaled using DAP as DS, 80-90% of the original flux was recovered when the crossflow velocity for physical cleaning was the same as the crossflow velocity during FDFO desalination. However, when a higher crossflow velocity or Reynolds number was used, the flux was recovered almost completely, irrespective of the DS concentration used. This study underscores the importance of selecting a suitable fertiliser for FDFO desalination of brackish groundwater to avoid membrane scaling and severe flux decline.

  1. Environmental and economic impacts of fertilizer drawn forward osmosis and nanofiltration hybrid system

    2017-05-08

    Environmental and economic impacts of the fertilizer drawn forward osmosis (FDFO) and nanofiltration (NF) hybrid system were conducted and compared with conventional reverse osmosis (RO) hybrid scenarios using microfiltration (MF) or ultrafiltration (UF) as a pre-treatment process. The results showed that the FDFO-NF hybrid system using thin film composite forward osmosis (TFC) FO membrane has less environmental impact than conventional RO hybrid systems due to lower consumption of energy and cleaning chemicals. The energy requirement for the treatment of mine impaired water by the FDFO-NF hybrid system was 1.08 kWh/m, which is 13.6% less energy than an MF-RO and 21% less than UF-RO under similar initial feed solution. In a closed-loop system, the FDFO-NF hybrid system using a TFC FO membrane with an optimum NF recovery rate of 84% had the lowest unit operating expenditure of AUD $0.41/m. Besides, given the current relatively high price and low flux performance of the cellulose triacetate and TFC FO membranes, the FDFO-NF hybrid system still holds opportunities to reduce operating expenditure further. Optimizing NF recovery rates and improving the water flux of the membrane would decrease the unit OPEX costs, although the TFC FO membrane would be less sensitive to this effect.

    In recent years, pre-strained TiNi shape memory alloys (SMA) have been used for fabricating smart structure with carbon fibers reinforced plastics (CFRP) in order to suppress microscopic mechanical damages. However, since the cure temperature of CFRP is higher than the reverse transformation temperatures of TiNi SMA, special fixture jigs have to be used for keeping the pre-strain during fabrication, which restricted its practical application. In order to overcome this difficulty, we developed a new method to fabricate SMA/CFRP smart composites without using special fixture jigs by controlling the transformation temperatures of SMA during fabrication. This method consists of using heavily cold-worked wires to increase the reverse transformation temperatures, and of using flash electrical heating of the wires after fabrication in order to decrease the reverse transformation temperatures to a lower temperature range again without damaging the epoxy resin around SMA wires. By choosing proper cold-working rate and composition of TiNi alloys, the reverse transformation temperatures were well controlled, and the TiNi/CFRP hybrid smart composite was fabricated without using special fixture jigs. The damage suppressing effect of cold drawn wires embedded in CFRP was confirmed.

    Full Text Available  Overall operational excellence is the key requirement of any business to have global competence and sustained growth. Indian industries are not the exception to this. Six Sigma has emerged as one of the most effective business improvement strategies world wide.  Nothing much has been published so far illustrating an overall experience of Indian industries with Six Sigma. This paper presents an analysis of the impact of Six Sigma on developing economy like India.  The paper provides an insight into what kind of benefits Indian industries are gaining from Six Sigma as a whole. The study further highlights similarity and differences of benefit gained by different scales and sectors of Indian industries through Six Sigma. This exhaustive analysis of the benefits drawn by Indian industries through Six Sigma can assist other industries in India as well as those in other developing countries, who have yet not experimented with Six Sigma, to become more focused regarding their expectations from this improvement drive. 

  5. Leadership and organisational effectiveness--lessons to be drawn from education?

    2009-05-01

    The aim of this paper is to present findings of a case study on organisational effectiveness in an education setting and draw similarities with a healthcare setting, focusing on the school principal and nurse leader. The study was carried out in a primary school setting and focuses on a principal (as leader). The school, which will be named St Senan's for the case study, is a typical tall structure, has a staff of 30 (teachers and special needs' assistants) and a student number of 117. A case study methodology was used. Data was collected by interviewing the principal, two teachers, two students and a parent, in this order. In addition, a Parents' Council meeting was observed and document analysis was carried out on measurements which reflected some critical success factors for the school. Interviews from students and teachers in addition to observation notes indicate that the principal's leadership impacts on organisational effectiveness in the school. The findings are located in the context of education with similarities being drawn from nursing. It is how the leader leads in the context of the organisation setting which is paramount. In other words it is not possible to take a set of general critical success factors for a school or healthcare setting and apply these widely. The paper concludes by proposing the use of a quality framework to contextualise the findings of the case and promote further discussion in the context of nurse leaders. The paper suggests that comparisons can be made between school principals and nurse leaders.

    Experiments were conducted on Cu–0.1wt.%Ag alloys to evaluate the influence of producing procedures and annealing conditions on microstructure evolution and mechanical properties of Cu–Ag alloys. Optical microscopy (OM), electron back-scattered diffraction (EBSD), X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used for microstructural evaluation and mechanical properties were characterized by tensile tests. The results indicated that hot-extruded Cu–Ag alloys had a typical dynamic recrystallized microstructure with equiaxed grains. Cold drawing at room temperature leaded to partial recrystallized microstructure with a mixture of coarse and fine grains. The dominate {001}<100 > cubic texture formed during hot extrusion was changed to be {112}<111 > copper texture by cold drawing. Strain softening occurred during room temperature tension of cold drawn Cu–Ag alloys with an average grain size of 13–19.7 μm. - Highlights: • Strain softening occurred during tension of Cu–Ag alloys with coarse grain size. • Work hardening was observed in hot-extruded and annealed Cu–0.1wt.%Ag alloys. • Strain softening was ascribed to dynamic recovery and dynamic recrystallization.

  7. Contribution of modulated DSc to study the thermal behaviour of PET films drawn in hot water

    2003-01-01

    PET films uni-axially drawn in hot water are studied by means of conventional DSc and modulated DSc. The glass transition is studied by modulated DSc which allows access to the values of the glass transition temperature T g and the variations of δ C p = C p 1-C p g (difference between thermal capacity in the liquid-like and glassy states at T = T g ). Variations of T g with the water content (which act as plasticizer) and with the drawing (which rigidifies the amorphous phase) are discussed in regard to the structure engaged in these materials. The variations of δ C p are also interpreted with the help of a three phase model and a strong-fragile glass former liquid concept. We show that the fragility of the medium increases by the conjugated effects of deformation and water as soon as a strain induced crystalline phase is obtained, and it decreases drastically when the rigid amorphous phase occurs.

  8. Yield strength of a heavily drawn Cu-20% Nb filamentary microcomposite

    Hong, S.I.

    1998-01-01

    It has been well documented that heavily-drawn, copper-niobium microcomposites possess high strength and high conductivity. Since niobium has little solubility in copper, the conductivity of the copper is not strongly affected by the addition of niobium. Following extensive mechanical deformation of Cu-Nb, niobium dendrites transform into fine niobium ribbons as a result of the niobium texture upon drawing. This nanostructure contributes to the ultrahigh strength of Cu-Nb microcomposites. The strength of heavily deformed Cu-Nb exceeds that predicted by the rule-of-mixtures (ROM), and a fundamental understanding of the strengthening mechanisms involved has been the subject of much discussion. Spitzig and his coworkers suggests a barrier strengthening model while Funkenbusch and Courtney believe that stored dislocations have a role in substructural hardening. Hangen and Raabe recently proposed an analytical model for the calculation of the yield strength of Cu-Nb microcomposite. The model of Hangen and Raabe and that of Spitzig and his coworkers have a great deal of resemblance since both models attribute the strength to the difficulty of propagating plastic flow through the interface. The purpose of this study was to enhance the understanding of the strengthening mechanisms associated with Cu-Nb microcomposites by examining the previous studies on mechanical and microstructural stability of Cu-based microcomposites

    Full Text Available Electronic capacitors were constructed via hand-printing on paper using pencil graphite. Graphite traces were used to draw conductive connections and capacitor plates on opposing sides of a sheet of standard notebook paper. The paper served as the dielectric separating the plates. Capacitance of the devices was generally < 1000 pF and scaled with surface area of the plate electrodes. By combining a pencil-drawn capacitor with an additional resistive pencil trace, an RC low-pass filter was demonstrated. Further utility of the pencil-on-paper devices was demonstrated through description of a capacitive force transducer and reversible chemical sensing. The latter was achieved for water vapor when the hygroscopic cellulose matrix of the paper capacitor’s dielectric adsorbed water. The construction and demonstration of pencil-on-paper capacitive elements broadens the scope of paper-based electronic circuits while allowing new opportunities in the rapidly expanding field of paper-based sensors.

    As guest editor of a recent Ethics in Science publication(S. R. Chubb, Accountability in Research, v 8), #'s 1 and 2, 1 (2000). journals/149/149-top.htm>(http://www.gbhap us.com/journals/149/149-top.htm), I requested key players, from both sides of the Cold Fusion (CF) debate, to attempt to go beyond questions involving the merits of CF, by addressing a more basic issue: have CF claims been judged effectively. All participants agreed that this has not occurred. Three factors seem to have been responsible: 1. Errors in the initial neutron measurements, 2. Events immediately prior to and during a specific APS session, held 1 May 1989, and 3. Irresponsible use of FAX machines and the Internet. The resulting furor, fueled by these Information Era Technologies (IET's), has evolved into such a serious breakdown in communication that, even after 11 years, it is impossible to rule-out the possibility that a number of important new discoveries may have occurred. Regardless of the merits of the claims, two lessons can be drawn from the debate: 1. Individuals and groups must be held accountable for their actions and statements, 2. When IET users fail to respect each other, IET's can seriously impede communication.

    Micropatterned surfaces with wettability contrast have attracted considerable attention due to potential applications in 2D microfluidics, bioassays, and water harvesting. A simple method to develop wettability contrast patterns on metallic surfaces by using a commercial marker is described. A marker-drawn ink pattern on a copper surface displays chemical resistance to an aqueous solution of sodium bicarbonate and ammonium persulfate, thereby enabling selective nanowire growth in areas where ink is absent. Subsequent ink removal by an organic solvent followed by fluorocarbon film deposition yields a stable hydrophobic/super-hydrophobic patterned copper surface. Using this approach, hydrophobic dot and line patterns were constructed. The adhesion force of water droplets to the dots was controlled by adjusting pattern size, thus enabling controlled droplet transfer between two surfaces. Anisotropy of water droplet adhesion to line patterns can serve as a basis for directional control of water droplet motion. This general approach has also been employed to generate wettability contrast on aluminum surfaces, thereby demonstrating versatility. Due to its simplicity, low cost, and virtual independence of solid surface material, ink marker pens can be employed to create wettability patterns for a variety of applications, in fields as diverse as biomedicine and energy.

    An overview of nearly thirty years development of waste gasification and pyrolysis technology is given, and some major general conclusions are drawn. The aim has been to give new developers an overview of earlier major attempts to treat MSW/RDF with thermochemical processes, gasification or pyrolysis. Research work in general is not covered, only R and D efforts that have led to substantial testing in pilot scale or demonstration. For further details, especially related to ongoing R and D, readers are referred to other recent reviews. The authors' view is that gasification of RDF with appropriate gas cleaning can play an important role in the future, for environmentally acceptable and efficient energy production. A prerequisite is that some of the major mistakes can be avoided, such as: (1) too rapid scale-up without experimental base, (2) unsuitable pretreatment of MSW to RDF and poor integration with material recycling, and (3) too limited gas/flue gas cleaning.

    Evolving technology has increased the focus on genomics. The combination of today's advanced techniques with decades of molecular biology research has yielded huge amounts of pathway data. A standard, named the Systems Biology Graphical Notation (SBGN), was recently introduced to allow scientists to represent biological pathways in an unambiguous, easy-to-understand and efficient manner. Although there are a number of automated layout algorithms for various types of biological networks, currently none specialize on process description (PD) maps as defined by SBGN. We propose a new automated layout algorithm for PD maps drawn in SBGN. Our algorithm is based on a force-directed automated layout algorithm called Compound Spring Embedder (CoSE). On top of the existing force scheme, additional heuristics employing new types of forces and movement rules are defined to address SBGN-specific rules. Our algorithm is the only automatic layout algorithm that properly addresses all SBGN rules for drawing PD maps, including placement of substrates and products of process nodes on opposite sides, compact tiling of members of molecular complexes and extensively making use of nested structures (compound nodes) to properly draw cellular locations and molecular complex structures. As demonstrated experimentally, the algorithm results in significant improvements over use of a generic layout algorithm such as CoSE in addressing SBGN rules on top of commonly accepted graph drawing criteria. An implementation of our algorithm in Java is available within ChiLay library (https://github.com/iVis-at-Bilkent/chilay). ugur@cs.bilkent.edu.tr or dogrusoz@cbio.mskcc.org Supplementary data are available at Bioinformatics online. © The Author 2015.

  15. Impact of reverse nutrient diffusion on membrane biofouling in fertilizer-drawn forward osmosis

    2017-05-31

    Biofouling in fertilizer-drawn forward osmosis (FDFO) for water reuse was investigated by spiking pure bacteria species Pseudomonas aeruginosa PAO1+GFP and using three different fertilizers KNO3, KCl and KH2PO4 as draw solutions. The performance of FO process for treating synthetic wastewater was assessed and their influence on the membrane fouling and in particular biofouling was evaluated relative to the type of different fertilizers used and their rates of reverse diffusion. FO performances using KNO3 as draw solute exhibited severer flux decline (63%) than when using KCl (45%) and KH2PO4 (30%). Membrane autopsy indicated that the mass of organic foulants and biomass on fouled membrane surface using KNO3 as draw solute (947.5mg/m2 biopolymers, 72µm biofilm thickness and 53.3mg/m2 adenosine triphosphate) were significantly higher than that using KCl (450mg/m2 biopolymers, 33µm biofilm thickness and 28.2mg/m2 ATP) and KH2PO4 (440mg/m2 biopolymers, 35µm biofilm thickness and 33.5mg/m2 ATP). This higher flux decline is likely related to the higher reverse diffusion of KNO3 (19.8g/m2/h) than KCl (5.1g/m2/h) and KH2PO4 (3.7g/m2/h). The reverse diffused potassium could promote the organics and bacterial adhesion on FO membrane via charge screening effect and compression of electrical double layer. Moreover, reverse diffused nitrate provided increased N:P nutrient ratio was favorable for the bacteria to grow on the feed side of the FO membrane.

  16. Forming parts over small radii

    Stamping simulations usually make the plane stress simplifying assumption. However, this becomes less valid when material draws around features with radius to sheet thickness ratios less than 20. Pereira, Yan and Rolfe (Wear, Vol.265, p.1687 (2008)) predicted that out-of-plane stress equivalent to material yield can occur because a line contact forms briefly at the start of the draw process. The high transient stress can cause high rates of tool wear and may cause the ‘die impact line’ cosmetic defect. In this work, we present residual strain results of a channel section that was drawn over a small radius. Using the neutron source at the Institut Laue-Langevin, in-plane and out-of-plane strains were measured in the channel part to show some support for the conclusions of Pereira et. al. (paper)

    This report presents the results of a study which explored the use of six different regulatory strategies for oversight of commercial nuclear power facilities: prescriptive, case-based, outcome-based, risk-based, process-based, and self-assessment strategies. Information was collected on experiences with the use of these different regulatory strategies from experts from nuclear regulatory agencies in Canada, Finland, Spain, Sweden, the United Kingdom and the United States. Systematic, structured open-ended interviews with expert regulators with extensive experience were used in order to understand how regulatory strategies are applied in practice. Common patterns were identified regarding: Experts' perspectives on the major benefits and difficulties of using specific regulatory strategies; Experts' experiences with using regulatory strategies for three areas of oversight-design and modifications, quality systems, and training and qualifications; Expert views of the consequences of different regulatory strategies; Issues that emerged in the interviews regarding regulatory strategies. The major benefit of a prescriptive strategy was that it is clear about requirements and expectations. The major difficulties were that it takes responsibility away from the licensee, it requires a high use of regulator resources and is rigid and difficult to change. A case-based strategy had the key benefit of flexibility for adapting regulatory responses to unique situations, but the difficulties of being considered arbitrary, inconsistent, and unfair and requiring heavy resource use. An outcome-based strategy had the main benefit of allowing licensees to decide the best way to operate m order to meet safety goals, but the major difficulty of identifying appropriate ways to measure safety performance. The major benefit of a risk strategy was its use co prioritize safety issues and allocate resources. However, it was considered inappropriate to use as a stand alone strategy and a strategy that had serious methodological and data problems. A process based strategy had a major benefit of providing in depth understanding of a licensee's performance. The main difficulties were that it was not considered effective unless the processes were linked to outcomes, and that it was complex to define and evaluate processes. The major benefit of a self assessment strategy was that it put responsibility for safety on the licensee, while the major difficulties were that it should not be used as a stand alone strategy and that it often does not have credibility with the general public. A few of the main findings regarding the experiences of using regulatory strategies for the areas of plant design and modifications, quality systems and training and qualifications included: Use of combinations of at least two, often three and at times four different strategies for specific examples of oversight issues; Less reliance on a prescriptive strategy in recent years, often moving toward more use of a process-based strategy, but return to a prescriptive strategy for action and closure when necessary; Use of a risk strategy to prioritize safety issues, activities and regulatory findings for oversight of both quality systems and plant design and modifications; Disagreements over the incorporation of a risk strategy into regulatory decision-making for plant design and modifications and attempts to balance the use of a combination of risk and prescriptive strategies for this area of oversight. Regulatory strategies were viewed as affecting: Whether the licensee or regulator takes primary responsibility for safety; How clear requirements and expectations are to licensees; Significance of safety issues identified; Expertise needed by regulators and licensees; Resources used by regulators and licensees; Flexibility given to licensees; Public credibility. Issues that emerged from examples regarding regulatory strategies: Resistance to changing regulatory strategies; Tension concerning the use of risk analysis for regulatory decisions; Differences in interpretations of regulatory strategy definitions; Importance of combinations of strategies for regulatory effectiveness.

    local waves. Better earthquake-hazard maps, based on improved knowledge of regional geology, fault behavior, and earthquake mechanisms, are needed for the entire country. Their preparation will require the close collaboration of engineers, seismologists, and geologists. Geologic maps of all inhabited places in earthquake-prone parts of the country are also needed by city planners and others, because the direct relationship between local geology and potential earthquake damage is now well understood. Improved and enlarged nets of earthquake-sensing instruments, sited in relation to known geology, are needed, as are many more geodetic and hydrographic measurements. Every large earthquake, wherever located, should be regarded as a full-scale laboratory experiment whose study can give scientific and engineering information unobtainable from any other source. Plans must be made before the event to insure staffing, funding, and coordination of effort for the scientific and engineering study of future earthquakes. Advice of earth scientists and engineers should be used in the decision-making processes involved in reconstruction after any future disastrous earthquake, as was done after the Alaska earthquake. The volume closes with a selected bibliography and a comprehensive index to the entire series of U.S. Geological Survey Professional Papers 541-546. This is the last in a series of six reports that the U.S. Geological Survey published on the results of a comprehensive geologic study that began, as a reconnaissance survey, within 24 hours after the March 27, 1964, Magnitude 9.2 Great Alaska Earthquake and extended, as detailed investigations, through several field seasons. The 1964 Great Alaska earthquake was the largest earthquake in the U.S. since 1700. Professional Paper 546, in 1 part, describes Lessons and Conclusions.

    The lessons drawn from operation are used to detect the weak points not taken sufficiently into account by the design studies and to check that system availability remains at least equal to the level defined at the design stage. In both cases, they aim at deciding what remedial actions are to be taken. The latter may result in additional obligations (modification or addition of equipment or operating rules) and, in certain cases, may slacken obligations. This paper examines in turn: how are the events recorded and then analyzed, what lessons are drawn using concrete examples, what contribution is made by probabilistic risk studies using experience feedback in evaluating overall safety [fr

  9. Cosmological Gamma-Ray Bursts and Hypernovae Conclusively Linked

    . Thousands of years prior to this explosion, a very massive star, running out of hydrogen fuel, let loose much of its outer envelope, transforming itself into a bluish Wolf-Rayet star [3]. The remains of the star contained about 10 solar masses worth of helium, oxygen and heavier elements. In the years before the explosion, the Wolf-Rayet star rapidly depleted its remaining fuel. At some moment, this suddenly triggered the hypernova/gamma-ray burst event. The core collapsed, without the outer part of the star knowing. A black hole formed inside, surrounded by a disk of accreting matter. Within a few seconds, a jet of matter was launched away from that black hole. The jet passed through the outer shell of the star and, in conjunction with vigorous winds of newly formed radioactive nickel-56 blowing off the disk inside, shattered the star. This shattering, the hypernova, shines brightly because of the presence of nickel. Meanwhile, the jet plowed into material in the vicinity of the star, and created the gamma-ray burst which was recorded some 2,650 million years later by the astronomers on Earth. The detailed mechanism for the production of gamma rays is still a matter of debate but it is either linked to interactions between the jet and matter previously ejected from the star, or to internal collisions inside the jet itself. This scenario represents the "collapsar" model, introduced by American astronomer Stan Woosley (University of California, Santa Cruz) in 1993 and a member of the current team, and best explains the observations of GRB 030329. " This does not mean that the gamma-ray burst mystery is now solved ", says Woosley . " We are confident now that long bursts involve a core collapse and a hypernova, likely creating a black hole. We have convinced most skeptics. We cannot reach any conclusion yet, however, on what causes the short gamma-ray bursts, those under two seconds long ."

  10. Structure evolution and mechanical behavior of poly(ethylene terephthalate fibers drawn at different number of drawing stages

    2012-01-01

    Full Text Available In this work, the structure, mechanical and thermal properties of PET fiber obtained by hot multi-stage drawing have been investigated in terms of their dependence on the number of drawing steps at an equivalent total draw ratio. Differential scanning calorimetry, birefringence, wide-angle x-ray diffraction, FTIR spectroscopy, tensile properties, and taut-tie molecules were used to characterize the fine structure and physical properties of the fibers. Results have been explained in terms of a higher drawing residence time at an equivalent drawing speed. For single stage drawn fiber, a high tensile strength is obtained, whereas a high initial modulus is obtained for fiber drawn at three-stage drawing. According to the results, an important finding is that three-stage drawing process has the potential to produce high-modulus fibers. The enhanced fraction of taut-tie molecules is found in three-stage drawn fiber, which is believed to be one of the important factors leading to the high modulus achieved in fibers drawn in hot multistage.

    We investigate the action of global noise and local channels, namely, amplitude-damping, phase-damping, and depolarizing channels, on monogamy of quantum correlations, such as negativity and quantum discord, in three-qubit systems. We discuss the monotonic and non-monotonic variation, and robustness of the monogamy scores. By using monogamy scores, we propose a two-step protocol to conclusively identify the noise applied to the quantum system, by using generalized Greenberger–Horne–Zeilinger and generalized W states as resource states. We discuss a possible generalization of the results to higher number of parties. - Highlights: • Monogamy score monotonically decays with noise for generalized GHZ state as input. • Non-monotonically decaying monogamy score with noise for generalized W state as input. • Characterizing the dynamics of monogamy score. • Dynamics terminal quantifying robustness of monogamy score against noise. • Conclusively identifying the type of noise using monogamy score.

  18. Review conclusions by Ernst and Canter regarding spinal manipulation refuted

    Directory of Open Access Journals (Sweden)

    Evans Roni

    2006-08-01

    Full Text Available Abstract In the April 2006 issue of the Journal of Royal Society of Medicine, Ernst and Canter authored a review of the most recent systematic reviews on the effectiveness of spinal manipulation for any condition. The authors concluded that, except for back pain, spinal manipulation is not an effective intervention for any condition and, because of potential side effects, cannot be recommended for use at all in clinical practice. Based on a critical appraisal of their review, the authors of this commentary seriously challenge the conclusions by Ernst and Canter, who did not adhere to standard systematic review methodology, thus threatening the validity of their conclusions. There was no systematic assessment of the literature pertaining to the hazards of manipulation, including comparison to other therapies. Hence, their claim that the risks of manipulation outweigh the benefits, and thus spinal manipulation cannot be recommended as treatment for any condition, was not supported by the data analyzed. Their conclusions are misleading and not based on evidence that allow discrediting of a large body of professionals using spinal manipulation.

    The new challenges in the field of Health and Safety at Work require the implementation of more comprehensive and participatory interventions, in order to have a real impact on the working conditions. Matriosca Model has sought over the years to involve workers in the construction of new working conditions, promoting transformation through training and recreating training from the transformation. This article seeks to present some of the results of the implementation of the Matriosca Model on a chemicals industrial company regarding the many changes that it promoted, how these changes have evolved through time, how the dimensions of training and transformation interact and what the participants' perception of the intervention was. The conclusions drawn allow a richer evaluation of the process, which can enhance the intercommunicating nature between training and transformation, and what impact this has on the actual work.

    Introduction plurihormonality of pituitary adenomas is an ability of adenoma cells to produce more than one hormone. After the immunohistochemical analysis had become a routine part of the morphological study, a great number of adenomas appeared to be multihormonal in actual practice. We hypothesize that the same cells of a normal pituitary gland releases several hormones simultaneously. Objective To analyse a possible co-expression of hormones by the cells of the normal anterior pituitary of...

  4. It pays to be green. A premature conclusion?

    It has been claimed that good environmental performance can improve firms' economic performance. However, because of e.g. data limitations, the methods applied in most previous quantitative empirical studies on effects of environmental performance on economic performance of firms suffer from several shortcomings. We discuss these shortcomings and conclude that previously applied methods are unsatisfactory as support for a conclusion that it pays for firms to be green. Then we illustrate the consequences of these shortcomings by performing several regression analyses of the effect of environmental performance on economic performance using a panel data set of Norwegian plants. A pooled regression where observable firm characteristics like e.g. size or industry are controlled for, confirms a positive effect of environmental performance on economic performance. However, the estimated positive effect could be due to omitted unobserved variables like management or technology. When the regression model controls for unobserved plant heterogeneity, the effect is generally no longer statistically significant. Hence, although greener plants tend to perform economically better, the analysis provides little support for the claim that it is because they are greener. These empirical findings further indicate that a conclusion that it pays to be green is premature

    Gold bonding wires have been manufactured through multiple drawing steps with serial and reverse-direction drawing. The texture and microstructure of the gold bonding wires were characterized with X-ray diffraction and EBSD and compared with the predictions of finite element (FE) simulation. Initial fiber decreases during drawing and is replaced by fiber. The oriented grains are concentrated in the center and surface regions, whereas the oriented grains are located throughout the cross-section of the wire. Regions near the surface often exhibit the complex textures. A simplified forward and backward drawing process was modeled by FE analysis with ABAQUS/Standard TM . The simple two-step drawing process results in severe variation in shear strain under the surface and displays the opposite behavior in the shear components of the deformation gradient. The texture evolution was predicted using the deformation gradient calculated in the FE simulations together with a model of polycrystal plasticity. The and fibers are predicted to develop in the center part of the wire where homogeneous deformation occurs. The regions near the surface that experience repeated shear strain exhibit complex textures that deviate from the standard and fibers. The {1 1 2} and {1 1 1} components are prevalent in the higher shear strain regions. The variations of the anisotropic elastic directional moduli with position were also calculated

  6. The social security scheme in Thailand: what lessons can be drawn?

    The Social Security Scheme was launched in 1990, covering formal sector private employees for non-work related sickness, maternity and invalidity including cash benefits and funeral grants. The scheme is financed by tripartite contributions from government, employers and employees, each of 1.5% of payroll (total of 4.5%). The scheme decided to pay health care providers, whether public or private, on a flat rate capitation basis to cover both ambulatory and inpatient care. Registration of the insured with a contractor hospital was a necessary consequence of the chosen capitation payment system. The aim of this paper is to review the operation of the scheme, and to explore the implications of capitation payment and registration for utilisation levels and provider behaviour. A key weakness of the scheme's design is suggested to be the initial decision to give employers not employees the responsibility for choosing the registered hospitals. This was done for administrative reasons, but it contributed to low levels of use of the contractor hospitals. In addition, low levels of use were also probably the result of the potential for cream skimming, cost shifting from inpatient to ambulatory care and under-provision of patient care, though since monitoring mechanisms by the Social Security Office were weak, these effects are difficult to detect conclusively. Mechanisms to improve utilisation levels were gradually introduced, such as employee choice of registered hospitals and the formation of sub-contractor networks to improve access to care. A beneficial effect of the capitation payment system was that the Social Security Fund generated substantial reserves and expenditures on sickness benefits were well stabilised. The paper ends by recommending that future policy amendments should be guided by research and empirical findings and that tougher monitoring and enforcement of quality of care standards are required.

    The ICT Benchmark exercise made within the RIV working group of ESARDA on reprocessing data supplied by COGEMA for 53 routines reprocessing input batches made of 110 irradiated fuel assemblies from KWO Nuclear Power Plant was finally evaluated. The conclusions are: all seven different ICT methods applied verified the operator data on plutonium within about one percent; anomalies intentionally introduced to the operator data were detected in 90% of the cases; the nature of the introduced anomalies, which were unknown to the participants, was completely resolved for the safeguards relevant cases; the false alarm rate was in a few percent range. The ICT Benchmark results shows that this technique is capable of detecting and resolving anomalies in the reprocessing input data to the order of a percent

    Yiftah, S.

    1979-07-01

    This work describes the first minutes, first day and first week following the Three Mile Island accident. It shows the failures that occurred and the lessons which should be derived. It is pointed out that the doses of radiation that escaped from the TMI plant were at no time large enough to have had any effect on the 2 million people living on a radius of 80 km from the plant. Although no casualties occurred the Harrisburg accident will create an impulse for a new study and understanding of the nuclear plant safety and might serve as a live safety laboratory. After the TMI accident nuclear plants are already safer, one of the conclusions being that a new planning of the operation room is required, with the operators acquiring a better understanding of what is going on during a nuclear reactor accident.

    The present study examined the jumping to conclusions reasoning bias across the continuum of delusional ideation by investigating individuals with active delusions, delusion prone individuals, and non-delusion prone individuals. Neutral and highly self-referent probabilistic reasoning tasks were employed. Results indicated that individuals with delusions gathered significantly less information than delusion prone and non-delusion prone participants on both the neutral and self-referent tasks, (preferent task (p=.002). Those with delusions and those who were delusion prone reported higher confidence in their performance on the self-referent task than they did the neutral task (p=.02), indicating that high self-reference impacted information processing for individuals in both of these groups. The results are discussed in relation to previous research in the area of probabilistic reasoning and delusions.

The activity was attended by experts from France (Angers, Martinique, French Guiana, Guadeloupe, and Paris), Costa Rica, Brazil, Saint Lucia, and Surinam. The epidemiology, clinical manifestations, clinical grading and the management of snakebite in French Guiana were discussed. The conclusions of this symposium illustrated the urgent need to ensure accessibility of effective and safe polyvalent viperid antivenom in French Guiana. Finally, the results of this symposium have forged ties based on mutual goals and objectives. Copyright © 2018 Elsevier Ltd. All rights reserved.

  13. Conclusions regarding geotechnical acceptability of the WIPP site

    1983-01-01

    The Waste Isolation Pilot Plant (WIPP) was authorized by Congress in 1980 as an unlicensed research and development (R and D) facility to demonstrate the safe disposal of radioactive wastes arising from the defense activities and programs of the United States. WIPP is now being constructed in southeast New Mexico, using salt beds about 655 m below the surface of the ground. Construction of the full WIPP facility will not commence until a preliminary underground excavation phase, called Site and Preliminary Design Validation (SPDV), is satisfactorily concluded in the summer of 1983. This SPDV program permits confirmation of subsurface geology, in drifts at planned facility depth that extend for 1555 m in a north-south direction, and in the two vertical shafts that provide access to these drifts. The subsurface studies are nearing completion, and it is therefore appropriate to draw conclusions regarding the geotechnical acceptability of the WIPP site. Four geotechnical elements are discussed: dissolution, deformation, hydrologic regime, and natural resources

    2014-01-01

    Full Text Available Tactile graphics are images that use raised surfaces so that a visually impaired person can feel them. Tactile maps are used by blind and partially sighted people when navigating around an environment, and they are also used prior to a visit for orientation purposes. Since the ability to read tactile graphics deeply depends on individuals, providing tactile graphics individually is needed. This implies that producing tactile graphics should be as simple as possible. Based on this background, we are developing a system for automating production of tactile maps from hand-drawn figures. In this paper, we first present a pattern recognition method for hand-drawn maps. The usability of our system is then evaluated by comparing it with the two different methods to produce tactile graphics.

Different solutions of classification have been proposed, following more or less two main approaches: Division of alliances and suballiances by ecologically or geographically orientated species groups. A new classification of European beech forests is proposed with 8 (or more geographically orientated alliances, which can be further divided into suballiances by ecological species groups. For each alliance character and differential species, nomenclatural type and the area is mentioned, based on a (non puplished synthetic table, including 10.006 relevés from all parts of Europe. From this table also some overlapping species groups (a-n are given.

    Results from the National Acid Precipitation Assessment Program (NAPAP) are discussed. Final results are contained in 26 state of the science reports. Seven of the reports provide information on acid rain and aquatic ecosystems. They describe the current state of acidic surface waters, watershed processes affecting surface water chemistry, historical evidence for surface water acidification, methods for forecasting future changes, and the response of acidic surface water to liming. Six areas of the country were found to be of special interest: southwest Adirondacks, New England, forested areas of the mid-Atlantic highlands, the Atlantic coastal plain, the northern Florida highlands, parts of northeastern Wisconsin and the Upper Peninsula of Michigan. Environmental effects, mitigation efforts and possible legislation are briefly discussed

    2004-01-01

    -utility threshold above the base-case results (n = 25) were of somewhat higher quality, and were more likely to justify their sensitivity analysis parameters, than those that did not (n = 45), but the overall quality rating was only moderate. Sensitivity analyses for economic parameters are widely reported and often identify whether choosing different assumptions leads to a different conclusion regarding cost effectiveness. Changes in HR-QOL and cost parameters should be used to test alternative guideline recommendations when there is uncertainty regarding these parameters. Changes in discount rates less frequently produce results that would change the conclusion about cost effectiveness. Improving the overall quality of published studies and describing the justifications for parameter ranges would allow more meaningful conclusions to be drawn from sensitivity analyses.

    Héctor García-Diego Villarías

    2018-04-01

    Full Text Available La Casa –or in English, the house– that Bernard Rudofsky built on the Spanish Mediterranean coast in 1971 is a valuable case study on the operational possibilities of popular architecture in the practice of this contemporary discipline. It is a repository of theoretical references typical of the vernacular world; its author, known for the exhibition Architecture without Architects, is emblematic of this type of architecture to which he dedicated much of his efforts as a theorist and polemicist throughout the course of his life. Additionally, La Casa is a unique architectural feat as it involves the practical materialization of its implicated theoretical position. It is possible that a concrete conclusion can be drawn from this case, which may shed light on the possible operability of a type of architecture that presents more than a few difficulties for the current context of the discipline, despite being habitually admired and praised. Additionally, the text presented here brings to light unpublished information found in the personal diaries of the architect that allows for the recreation of the circumstances surrounding the ideation and construction of this piece of architecture.

  1. A conclusive scalable model for the complete actuation response for IPMC transducers

    International Nuclear Information System (INIS)

    McDaid, A J; Aw, K C; Haemmerle, E; Xie, S Q

    2010-01-01

    This paper proposes a conclusive scalable model for the complete actuation response for ionic polymer metal composites (IPMC). This single model is proven to be able to accurately predict the free displacement/velocity and force actuation at varying displacements, with up to 3 V inputs. An accurate dynamic relationship between the force and displacement has been established which can be used to predict the complete actuation response of the IPMC transducer. The model is accurate at large displacements and can also predict the response when interacting with external mechanical systems and loads. This model equips engineers with a useful design tool which enables simple mechanical design, simulation and optimization when integrating IPMC actuators into an application. The response of the IPMC is modelled in three stages: (i) a nonlinear equivalent electrical circuit to predict the current drawn, (ii) an electromechanical coupling term and (iii) a segmented mechanical beam model which includes an electrically induced torque for the polymer. Model parameters are obtained using the dynamic time response and results are presented demonstrating the correspondence between the model and experimental results over a large operating range. This newly developed model is a large step forward, aiding in the progression of IPMCs towards wide acceptance as replacements to traditional actuators

  2. Summary of the discussion, Conclusion of the meeting

    Crutzen, S.

    1997-01-01

    The discussion was organised in three major periods corresponding to the main themes developed by the programme of the meeting: the qualification approaches, the qualification experience accumulated so far, one particular frame or motivation of the ISI qualification: the risk based (or informed) ISI. The qualification approaches presented by national representatives raised few questions. More discussion was induced on the qualification concepts, responsibilities, need and writing of the technical justification, motivation for the open trials, similitude between concepts, benefit deriving from the qualification of inspection procedures and further motivation. the conclusion could be as the following: the evolution of qualification applications, even if issued from harmonised concepts, appears to be nationalistically based. It is a thought that emulation and harmonisation could actually produce both savings and improvements in this area. 'The wheel does not have to be re-invented in each country' and it is the declared objective of ENIQ. There seems to be a need for some international agreement in the setting of standards for qualification. One area which seems to continue to be of underlying concern is in the characterisation of defects. There seems to be a need for appropriate 'defected blocks' satisfying the criteria of representativeness, quality, low cost, reproducibility, etc. More specific cases of Technical Justification development are needed to serve as examples and incentive for the case of this element of inspection qualification

    The publication in january 2004 in the British medical journal of the article of P. Hall and coll. 'Effect of low doses of ionizing irradiation in infancy on cognitive function in adulthood: Swedish population based cohort study, has been noticed by the Radiation protection group of the French speaking society of pediatrics imaging. The authors evaluate the psycho-motor development of less eighteen months years old children and irradiated between 1930 and 1959 for a face angioma. They study for each dose of irradiation ( from 0 to 250 m Gy) the level of school attendance and their results to the psycho-motor tests made during conscription medical examination. They noticed a diminution of 50% of the access success rate to university for the children having received an irradiation dose of 250 mG. No effect is noticed under the irradiation dose of 100 mGy. In their conclusions the authors compare these irradiation doses to these ones delivered in brain scanner examination. These results seem overestimated compared with the work made on fetuses ( publication 84 of ICRP) then the fetus is considered as more sensitive to ionizing radiations than the infant. The dose of 120 mGy is found in the literature and now the dose delivered in pediatrics are in the area of 0 and 100 mGy where no effect has been revealed in the cohort of irradiated children. The article does not include the principle of justification that is used nowadays and the replacement by the trans fontanel echography has allowed to reduce the number of brain scanner, used only for limited cases where the benefit is superior the the risk of irradiation.

  4. Definition of sampling units begets conclusions in ecology: the case of habitats for plant communities.

    In ecology, expert knowledge on habitat characteristics is often used to define sampling units such as study sites. Ecologists are especially prone to such approaches when prior sampling frames are not accessible. Here we ask to what extent can different approaches to the definition of sampling units influence the conclusions that are drawn from an ecological study? We do this by comparing a formal versus a subjective definition of sampling units within a study design which is based on well-articulated objectives and proper methodology. Both approaches are applied to tundra plant communities in mesic and snowbed habitats. For the formal approach, sampling units were first defined for each habitat in concave terrain of suitable slope using GIS. In the field, these units were only accepted as the targeted habitats if additional criteria for vegetation cover were fulfilled. For the subjective approach, sampling units were defined visually in the field, based on typical plant communities of mesic and snowbed habitats. For each approach, we collected information about plant community characteristics within a total of 11 mesic and seven snowbed units distributed between two herding districts of contrasting reindeer density. Results from the two approaches differed significantly in several plant community characteristics in both mesic and snowbed habitats. Furthermore, differences between the two approaches were not consistent because their magnitude and direction differed both between the two habitats and the two reindeer herding districts. Consequently, we could draw different conclusions on how plant diversity and relative abundance of functional groups are differentiated between the two habitats depending on the approach used. We therefore challenge ecologists to formalize the expert knowledge applied to define sampling units through a set of well-articulated rules, rather than applying it subjectively. We see this as instrumental for progress in ecology as only rules

    plurihormonality of pituitary adenomas is an ability of adenoma cells to produce more than one hormone. After the immunohistochemical analysis had become a routine part of the morphological study, a great number of adenomas appeared to be multihormonal in actual practice. We hypothesize that the same cells of a normal pituitary gland releases several hormones simultaneously. To analyse a possible co-expression of hormones by the cells of the normal anterior pituitary of adult humans in autopsy material. We studied 10 pituitary glands of 4 women and 6 men with cardiovascular and oncological diseases. Double staining immunohistochemistry using 11 hormone combinations was performed in all the cases. These combinations were: prolactin/thyroid-stimulating hormone (TSH), prolactin/luteinizing hormone (LH), prolactin/follicle-stimulating hormone (FSH), prolactin/adrenocorticotropic hormone (ACTH), growth hormone (GH)/TSH, GH/LH, GH/FSH, GH/ACTH, TSH/LH, TSH/FSH, TSH/ACTH. Laser Confocal Scanning Microscopy with a mixture of primary antibodies was performed in 2 cases. These mixtures were ACTH/prolactin, FSH/prolactin, TSH/prolactin, ACTH/GH, and FSH/GH. We found that the same cells of the normal adenohypophysis can co-express prolactin with ACTH, TSH, FSH, LH; GH with ACTH, TSH, FSH, LH, and TSH with ACTH, FSH, LH. The comparison of the average co-expression coefficients of prolactin, GH and TSH with other hormones showed that the TSH co-expression coefficient was significantly the least (9,5±6,9%; 9,6±7,8%; 1,0±1,3% correspondingly). Plurihormonality of normal adenohypophysis is an actually existing phenomenon. Identification of different hormones in pituitary adenomas enables to find new ways to improve both diagnostic process and targeted treatment.

  7. Implementation of severe accident management measures - Summary and conclusions

    2002-01-01

    implemented in various ways in many plants, but not yet in all plants. A systematic approach, which is based upon a clearly defined decision-making process, is one of the features implemented in many cases. Available means are determined and priorities are set. This approach is made up of strategies intended to become an optimum approach to prevent or mitigate the consequences of beyond-design basis accidents. It is based upon a prepared information package about plant-specific behaviour to be expected in beyond design scenarios. The approaches followed in the different countries do not fit one single pattern. Harmonization, to the extent it is desirable, does not seem feasible at this stage. As a rule, the responsibility of the plant owner for the safety of his plant remains untouched. Also, safety goals may vary between countries.

    The publication in january 2004 in the British medical journal of the article of P. Hall and coll. 'Effect of low doses of ionizing irradiation in infancy on cognitive function in adulthood: Swedish population based cohort study, has been noticed by the Radiation protection group of the French speaking society of pediatrics imaging. The authors evaluate the psycho-motor development of less eighteen months years old children and irradiated between 1930 and 1959 for a face angioma. They study for each dose of irradiation ( from 0 to 250 m Gy) the level of school attendance and their results to the psycho-motor tests made during conscription medical examination. They noticed a diminution of 50% of the access success rate to university for the children having received an irradiation dose of 250 mG. No effect is noticed under the irradiation dose of 100 mGy. In their conclusions the authors compare these irradiation doses to these ones delivered in brain scanner examination. These results seem overestimated compared with the work made on fetuses ( publication 84 of ICRP) then the fetus is considered as more sensitive to ionizing radiations than the infant. The dose of 120 mGy is found in the literature and now the dose delivered in pediatrics are in the area of 0 and 100 mGy where no effect has been revealed in the cohort of irradiated children. The article does not include the principle of justification that is used nowadays and the replacement by the trans fontanel echography has allowed to reduce the number of brain scanner, used only for limited cases where the benefit is superior the the risk of irradiation.

  11. OECD/SERENA Project Report. Summary and Conclusions

    International Nuclear Information System (INIS)

    2015-02-01

    involving nominally 20 kilograms of prototypic melt. The analytical programme was aimed at complementing the analytical work in WGAMA/SERENA activity, completed in 2006, by integrating the results of the experimental programme in the current phase, and by updating the capabilities of the FCI models/codes for use in reactor safety analysis. The scope of the reactor application exercise was to verify whether progress made in the SERENA programme in understanding and modelling key FCI phenomena for reactor applications (mainly phenomena related to premixing, e.g., jet fragmentation, voiding, melt solidification, etc., as well as the role of melt properties) contributed to a reduction of scatter in code predictions for ex-vessel FCI, observed in the WGAMA/SERENA activity. A better consistency of the results was noted between various FCI codes although some discrepancies still exist on the absolute values. The scatter in most 2-D simulations is more due to the ultimate choice of the parameters (e.g., fragmentation criteria in the explosion phase) than to fundamental differences in the physics. This discrepancy will reduce further when the codes will have improved models based on the new experimental data produced in the project. Note the current experimental data have not been fully capitalised yet; accordingly, it will take some time to improve the models. The OECD/SERENA project accomplished in large part its stated objectives. The project generated new experimental data for development of new phenomenological models closed to real reactor case conditions (corium composition), improvement of existing models, and assessment of FCI codes. The project also provided new insights; however, it would be sometime before the insights can be fully integrated into new and improved models and codes. It should be noted that the FCI models and codes can only be as precise as the experimental data and that there are inherent uncertainties in experimental data. While from a regulatory and

  13. Evolution of carbon distribution and mechanical properties during the static strain ageing of heavily drawn pearlitic steel wires

    Lamontagne, A.; Massardier, V.; Sauvage, X.; Kléber, X.; Mari, D.

    2016-01-01

    The static strain ageing of heavily cold-drawn pearlitic steel wires was investigated using both global techniques and local techniques (Atom Probe Tomography (APT)), in order to highlight how the cold-drawn destabilized microstructure returns to a more stable state during post-drawing treatments between 20 °C and 150 °C. The global techniques (thermoelectric power, differential scanning calorimetry) clearly showed that ageing occurs in three successive ageing stages and is due to a redistribution of the carbon atoms coming from the strain-induced cementite dissolution. The first ageing stage was unambiguously attributed to the carbon segregation to the defects, while the second and third stages were interpreted as being due to the precipitation of intermediate carbides (2nd stage) and cementite (3rd stage). The true strain was not found to significantly affect the ageing kinetics and mechanisms but appeared to play a role in the amount of carbon atoms involved in the different ageing stages. APT analyses confirmed that ageing is governed by the carbon depletion of strain-induced supersaturated ferrite. The strengthening mechanisms associated with the different ageing stages were also discussed.

    The rapid development of biomedical materials with the advanced functional characteristics is a challenging task because of the growing demands for better material properties in-clinically employed. Modern medical devices that can be implanted into humans have evolved steadily by replacing TiNi-based alloys for titanium and stainless steel. In this study, the effect of the mechano-chemical treatment on structural properties of the matrix and surface layer of the drawn TiNi-based alloy wire was assessed. A range of samples have been prepared using different drawing and etching procedures. It is clear from the results obtained that the fabricated samples show a composite structure comprising the complex matrix and textured oxycarbonitride spitted surface layer. The suggested method of surface treatment is a concept to increase the surface roughness for the enhanced bio-performance and better in vivo integration.

  18. Selection of suitable fertilizer draw solute for a novel fertilizer-drawn forward osmosis-anaerobic membrane bioreactor hybrid system

    KAUST Repository

    Kim, Youngjin

    2016-02-09

    In this study, a protocol for selecting suitable fertilizer draw solute for anaerobic fertilizer-drawn forward osmosis membrane bioreactor (AnFDFOMBR) was proposed. Among eleven commercial fertilizer candidates, six fertilizers were screened further for their FO performance tests and evaluated in terms of water flux and reverse salt flux. Using selected fertilizers, bio-methane potential experiments were conducted to examine the effect of fertilizers on anaerobic activity due to reverse diffusion. Mono-ammonium phosphate (MAP) showed the highest biogas production while other fertilizers exhibited an inhibition effect on anaerobic activity with solute accumulation. Salt accumulation in the bioreactor was also simulated using mass balance simulation models. Results showed that ammonium sulphate and MAP were the most appropriate for AnFDFOMBR since they demonstrated less salt accumulation, relatively higher water flux, and higher dilution capacity of draw solution. Given toxicity of sulphate to anaerobic microorganisms, MAP appears to be the most suitable draw solution for AnFDFOMBR.

    The phenomenon of intergranular stress corrosion cracking in BWR stainless steel piping joints is well understood, and does not present a safety hazard as leak before break can be shown. It is recommended that work should proceed to reduce the probability of stress corrosion cracking by changing the BWR environment by hydrogen feedwater additions to remove oxygen. The cause of LWR pipe cracking is understood to be thermal fatigue caused by thermal stratifications at low flow rates during operation (PWR) and thermal mixing in piping tees (PWR). Recommendations include, research on corrosion fatigue crack propagation, evaluation of compressive stress state, design changes, and additional development of NDT methods for detection and sizing of cracks. Conclusions drawn steam generator tube degradation suggest that this is a potentially large problem. Recommendation include the use of stress corrosion resistant materials, oxygen reduction through use of deaeration feed banks, and inclusion in future design of inspection access to evaluate conditions of steam generators.

    Laux, Johannes; Röbel, Andreas; Parzeller, Markus

    2013-01-01

    The generic term "passive euthanasia" includes different issues dealing with the omission, discontinuation or termination of life-sustaining or life-prolonging medical treatments. The debate around passive euthanasia focuses on the constitutional right of self-determination of every human being on the one hand and the constitutional mandate of the State to protect human life on the other. Issues of passive euthanasia always require a differentiated approach. Essentially, it comes down to the following: In Germany, the human right of self-determination includes the right to prohibit the performance of life-sustaining treatments, even if this leads to the death of the patient. A physician who does not take life-sustaining treatment measures because this is the free will expressed by the patient is not subject to prosecution. On the other hand, if the physician treats the patient against his will, this can be deemed a punishable act of bodily injury. The patient's will is decisive even if his concrete state of health does no longer allow him to freely express his will. In the Patient's Living Will Act of 2009, the German legislator clarified the juridical assessment of such constellations being of particular relevance in practice. A written living will of a person in which he requests to take or not to take certain medical treatment measures in case that he is no longer able to make the decision himself shall be binding for the people involved in the process of medical treatment. If there is no living will, the supposed will of the patient shall be relevant. In its judgment in the "Putz case", the German Federal Court of Justice ruled in 2010 that actions terminating a life-sustaining treatment that does not correspond to the patient's will must be limited to letting an already ongoing disease process run its course. In this context it is not important, however, whether treatment is discontinued by an active act or by omission. Under certain circumstances, the termination of life-sustaining measures can also be permitted if they are no longer medically indicated. Looking to other European countries and the USA it becomes evident that euthanasia is the subject of controversial discussion and interpretation not only in Germany.

    The European community has to face several challenges in the domain of energy like the increasing dependence of fossil fuel imports, the volatility of energy prices, the increasing world energy demand, the threats of climatic changes and the slowness of energy efficiency improvements. This situation has led the European commission to preconize a consistent common European energy policy based on three main goals: reinforcing the security of supplies, warranting the competitiveness of European economies and an affordable energy supplies cost both for companies and consumers and in a stable regulatory framework, and promoting the environmental viability through the improvement of energy efficiency, the development of renewable energy sources and the reexamination of the carbon trading system. The measures to be implemented for the realization of these goals are detailed. (J.S.)

  6. Assessing the removal of organic micro-pollutants from anaerobic membrane bioreactor effluent by fertilizer-drawn forward osmosis

    KAUST Repository

    Kim, Youngjin

    2017-03-23

    In this study, the behavior of organic micro-pollutants (OMPs) transport including membrane fouling was assessed in fertilizer-drawn forward osmosis (FDFO) during treatment of the anaerobic membrane bioreactor (AnMBR) effluent. The flux decline was negligible when the FO membrane was oriented with active layer facing feed solution (AL-FS) while severe flux decline was observed with active layer facing draw solution (AL-DS) with di-ammonium phosphate (DAP) fertilizer as DS due to struvite scaling inside the membrane support layer. DAP DS however exhibited the lowest OMPs forward flux or higher OMPs rejection rate compared to other two fertilizers (i.e., mono-ammonium phosphate (MAP) and KCl). MAP and KCl fertilizer DS had higher water fluxes that induced higher external concentration polarization (ECP) and enhanced OMPs flux through the FO membrane. Under the AL-DS mode of membrane orientation, OMPs transport was further increased with MAP and KCl as DS due to enhanced concentrative internal concentration polarization while with DAP the internal scaling enhanced mass transfer resistance thereby lowering OMPs flux. Physical or hydraulic cleaning could successfully recover water flux for FO membranes operated under the AL-FS mode but only partial flux recovery was observed for membranes operated under AL-DS mode because of internal scaling and fouling in the support layer. Osmotic backwashing could however significantly improve the cleaning efficiency.

    In this report, we describe 2 instances in which expert use of an electronic health record (EHR) system interfaced to an external clinical laboratory information system led to unintended consequences wherein 2 patients failed to have laboratory tests drawn in a timely manner. In both events, user actions combined with the lack of an acknowledgment message describing the order cancellation from the external clinical system were the root causes. In 1 case, rapid, near-simultaneous order entry was the culprit; in the second, astute order management by a clinician, unaware of the lack of proper 2-way interface messaging from the external clinical system, led to the confusion. Although testing had shown that the laboratory system would cancel duplicate laboratory orders, it was thought that duplicate alerting in the new order entry system would prevent such events. © The Author 2017.

  12. Fertilizer drawn forward osmosis process for sustainable water reuse to grow hydroponic lettuce using commercial nutrient solution

    KAUST Repository

    Chekli, Laura

    2017-03-10

    This study investigated the sustainable reuse of wastewater using fertilizer drawn forward osmosis (FDFO) process through osmotic dilution of commercial nutrient solution for hydroponics, a widely used technique for growing plants without soil. Results from the bench-scale experiments showed that the commercial hydroponic nutrient solution (i.e. solution containing water and essential nutrients) exhibited similar performance (i.e., water flux and reverse salt flux) to other inorganic draw solutions when treating synthetic wastewater. The use of hydroponic solution is highly advantageous since it provides all the required macro- (i.e., N, P and K) and micronutrients (i.e., Ca, Mg, S, Mn, B, Zn and Mo) in a single balanced solution and can therefore be used directly after dilution without the need to add any elements. After long-term operation (i.e. up to 75% water recovery), different physical cleaning methods were tested and results showed that hydraulic flushing can effectively restore up to 75% of the initial water flux while osmotic backwashing was able to restore the initial water flux by more than 95%; illustrating the low-fouling potential of the FDFO process. Pilot-scale studies demonstrated that the FDFO process is able to produce the required nutrient concentration and final water quality (i.e., pH and conductivity) suitable for hydroponic applications. Coupling FDFO with pressure assisted osmosis (PAO) in the later stages could help in saving operational costs (i.e., energy and membrane replacement costs). Finally, the test application of nutrient solution produced by the pilot FDFO process to hydroponic lettuce showed similar growth pattern as the control without any signs of nutrient deficiency.

  14. The prospects for nuclear power in the UK. Conclusions of the Government's nuclear review

    International Nuclear Information System (INIS)

    1995-05-01

    The conclusions of the United Kingdom government's review of the nuclear industry in Britain were presented to Parliament in May 1995. The provision of public sector support for a new nuclear power station is deemed unwarranted against the background of the current electricity market. In reaching this conclusion the government considered possible environmental and strategic advantages, the question of diversity of fuel sources, and wider economic benefits. It is intended to privatize parts of Nuclear Electric and Scottish Nuclear in 1996 as subsidiaries of a single holding company to take over the UK's AGR and PWR stations together with a significant level of their associated liabilities. A publicly owned company will continue to run the magnox stations and retain their liabilities. British Nuclear Fuels Ltd (BNFL) will continue to offer nuclear fuel services and to receive government support in developing business in overseas markets. Since their formation in 1990, Nuclear Electric and Scottish Nuclear have improved their financial performance significantly. At privatisation the nuclear component of the fossil fuel levy will cease to be paid to Nuclear Electric and Scottish Nuclear will no longer receive the current premium price paid under the Nuclear Energy Agreement. The current regulatory regime and rigorous safety standards for nuclear power will remain substantially unchanged. (UK)

  15. Development integration via real and technological convergence. Experience of Poland and conclusions for Ukraine

    Full Text Available The paper summarizes main achievements, losses and gains during the first decade of Poland's membership in the EU, while also aiming at development of suggestions for the Polish economic policy in the years to come, as well as draws conclusions for Ukraine, which has now elected the strategy of international economic cooperation. The first part of the paper presents an empirical analysis of Poland's both real and technological convergence with the developed EU countries. These data show that since 1994, as the process of Poland integration with the EU commenced, our country significantly reduced the income and technology gap as compared to the EU. During the financial crisis, Poland 'felt' better than most European countries. In the second part of the paper we attempt to answer the question as to the current conditions of Polish economy development. It is demonstrated that Poland's economic success was due to multiple factors such as endogenous and exogenous, historical and those derived from present events. However, it can be assumed that integration with the EU has been an important positive factor in development of Poland during recent 20 years. Great importance was also vested in the implementation of economic reforms in Poland as well as in policy of the government, although not faultless. The last section of the paper identifies problems now faced by the EU and individual member states, including Poland as regards future years till 2020

    Purpose: To evaluate the correlation between image features and the accuracy of manually drawn target contours on synthetic PET images Methods: A digital PET phantom was used in combination with Monte Carlo simulation to create a set of 26 simulated PET images featuring a variety of tumor shapes and activity heterogeneity. These tumor volumes were used as a gold standard in comparisons with manual contours delineated by 10 radiation oncologist on the simulated PET images. Metrics used to evaluate segmentation accuracy included the dice coefficient, false positive dice, false negative dice, symmetric mean absolute surface distance, and absolute volumetric difference. Image features extracted from the simulated tumors consisted of volume, shape complexity, mean curvature, and intensity contrast along with five texture features derived from the gray-level neighborhood difference matrices including contrast, coarseness, busyness, strength, and complexity. Correlation between these features and contouring accuracy were examined. Results: Contour accuracy was reasonably well correlated with a variety of image features. Dice coefficient ranged from 0.7 to 0.90 and was correlated closely with contrast (r=0.43, p=0.02) and complexity (r=0.5, p<0.001). False negative dice ranged from 0.10 to 0.50 and was correlated closely with contrast (r=0.68, p<0.001) and complexity (r=0.66, p<0.001). Absolute volumetric difference ranged from 0.0002 to 0.67 and was correlated closely with coarseness (r=0.46, p=0.02) and complexity (r=0.49, p=0.008). Symmetric mean absolute difference ranged from 0.02 to 1 and was correlated closely with mean curvature (r=0.57, p=0.02) and contrast (r=0.6, p=0.001). Conclusion: The long term goal of this study is to assess whether contouring variability can be reduced by providing feedback to the practitioner based on image feature analysis. The results are encouraging and will be used to develop a statistical model which will enable a prediction of

    Labs, K.

    The regional suitability of underground construction as a climate-control technique is discussed with reference to (1) a bioclimatic analysis of long-term weather data for 29 locations in the United States to determine appropriate above-ground climate-control techniques, (2) a data base of synthesized ground temperatures for the coterminous United States, and (3) monthly dewpoint ground temperature comparisons for identifying the relative likelihood of condensation, from one region to another. It is concluded that the suitability of earth tempering as a practice and of specific earth-sheltered design stereotypes varies geographically. While the subsurface almost always provides a thermal advantage on its own terms when compared to above-ground climatic data, it can, nonetheless, compromise the effectiveness of other, regionally more important climate-control techniques. Also contained in the report are reviews of above- and below-ground climate mapping schemes related to human comfort and architectural design, and a detailed description of a theoretical model of ground temperature, heat flow, and heat storage in the ground. Strategies of passive climate control are presented in a discussion of the building bioclimatic analysis procedure which has been applied in a computer analysis of 30 years of weather data for each of 29 locations in the United States. 3 references, 12 figures, 14 tables.

    The Tyndall decarbonisation scenarios project has outlined alternative pathways whereby a 60% reduction in CO 2 emissions from 1990 levels by 2050, a goal adopted by the UK Government, can be achieved. This paper, Part I of a two part paper, describes the methodology used to develop the scenarios and outlines the motivations for the project. The study utilised a backcasting approach, applied in three phases. In phase one, a set of credible and consistent end-points that described a substantially decarbonised energy system in 2050 were generated and reviewed by stakeholders. In phase two, pathways were developed to achieve the transition to the desired end-point. The impacts of the scenarios were assessed in phase three, by means of a deliberative multi-criteria assessment framework. The scenarios to emerge from this process are elaborated in Part II, and conclusions drawn in relation to the feasibility of achieving the 60% target

    Neonatal sepsis is the most frequent health care-associated infection in neonatal units. This study aimed to analyze articles on the clinical usefulness of catheter-drawn blood samples and catheter tip cultures for the diagnosis of intravascular catheter-related bloodstream infection (CRBSI) in neonates. A systematic search was performed for studies published from 1987-2017, without language restriction. Observational studies carried out in neonates with CRBSI diagnosed using catheter-drawn blood samples or catheter tip cultures were included. A total of 412 articles were identified in the databases and 10 articles were included. The 7 studies that evaluated central venous catheter tip cultures and cultures of catheter fragments presented sensitivities ranging from 58.5%-100% and specificities ranging from 60%-95.7%. Three studies that evaluated catheter-drawn blood cultures, paired with peripheral blood cultures, reported sensitivity and specificity of 94% and 71% when evaluated for the differential time to positivity. When quantitative evaluation was performed, the sensitivity and specificity were 80% and 99.4%. Most of the studies analyzed cultures from the central venous catheter tip and catheter fragments for the diagnosis of CRBSI in neonatal populations. The results of this review suggest that the analysis of the catheter-drawn blood samples and catheter tip cultures, paired with peripheral blood cultures, are efficient methods for the diagnosis of CRBSI in neonates.

    In this study, the presence of gold in the coatings of the emperor D. Pedro’s II Berlin device, part of the Imperial Museum of Petropolis, Brazil, was verified. Then perform was evaluation of the thickness of the gold leaf, using the technique of X-Ray Fluorescence, measuring peak intensities (Kα / Kβ or Lα / Lβ) of the elements of interest in the layer. It was possible to verify in the XRF spectra the presence of four elements: Ti, Fe, Au and Pb. The Pb was present at all sampling points, which indicates the presence of lead carbonate (lead-white) as preparation layer. The presence of Au at some sampling points indicates that several parts of the Berlin devices were covered with gold leaf. The presence of Ti and Fe is due to the application of golden mica over the entire length of the berlin device during the process of last restoration. The presence of the mica layer on the gold covering was relevant for gold thickness determination. The average value of the gold thickness obtained was 0.62 ± 0.51 μm, with a coefficient of variation of 83% and a confidence interval of 0.49-0.75 μm (α = 0.05). The values are compatible with the thickness of gold foil normally found in the coating of pieces of wood from the same period that the Berlin device was built. (author)

  4. Summary and conclusions of the specialist meeting on severe accident management programme development

    International Nuclear Information System (INIS)

    1992-01-01

    The CSNI Specialist meeting on severe accident management programme development was held in Rome and about seventy experts from thirteen countries attended the meeting. A total of 27 papers were presented in four sessions, covering specific aspects of accident management programme development. It purposely focused on the programmatic aspects of accident management rather than on some of the more complex technical issues associated with accident management strategies. Some of the major observations and conclusions from the meeting are that severe accident management is the ultimate part of the defense in depth concept within the plant. It is function and success oriented, not event oriented, as the aim is to prevent or minimize consequences of severe accidents. There is no guarantee it will always be successful but experts agree that it can reduce the risks significantly. It has to be exercised and the importance of emergency drills has been underlined. The basic structure and major elements of accident management programmes appear to be similar among OECD member countries. Dealing with significant phenomenological uncertainties in establishing accident management programmes continues to be an important issue, especially in confirming the appropriateness of specific accident management strategies

    Because of the importance of PWR components life management represents for Electricity Companies, significant R and D programs are dedicated to identifying and analysing mechanisms and damage rates of the different degradation modes of these components, systems and structures. To assess R and D assumptions and to validate non destructive test results through reviews, expert survey programs on in-situ equipment may enhance the knowledge about most of the various phenomena involved. In this regard, an extensive program was launched after the Chooz A NPP was decommissioned in 1991, after 24 years in operation. This program gathered EDF, IPSN, FRAMATOME, ELECTRABEL and TRACTEBEL into partnership. The expert survey program was performed in various laboratories between 1995 and 1999 and includes: - on-site non destructive testing before sampling, - and metallurgical and mechanical tests performed on samples taken from the nuclear and non nuclear part of the unit. The expert survey program performed by Utilities in various laboratories involved the following equipment: - reactor vessel and internal equipment, - reactor coolant system (dissimilar metal welds, SS welds, cast austenitic ferritic steels), - feedwater plant piping (erosion-corrosion), - electric cables susceptible of temperature and irradiation induced ageing, - anchoring in civil engineering structures, - main primary circuit concerning activation measurement. In conclusion, the extensive Chooz A expert survey program yields numerous significant results. The main outcomes will contribute to validate non destructive tests and enhance our knowledge of some degradation mechanisms of often quite similar components present in units in operation. It is worthy to note that this program is of prime importance for operation feedback; the cost of the whole study amounts to approximately 10 Million Euros. (author)

    To assess the conclusiveness of Cochrane reviews in the field of gynaecological cancer. The Cochrane Library was searched for reviews regarding gynaecological cancer published between 1 January 2000 and 1 November 2014. Data were extracted from each paper and the conclusiveness of each review was assessed. The study included 66 reviews, 41 (62.1%) of which were conclusive. Of these, 58 included randomized controlled trials (RCTs), 37 (63.8%) of which were conclusive. Conclusive reviews of RCTs included significantly more patients than inconclusive reviews, but there was no difference in the number of included studies. Of the eight reviews of nonrandomized studies, four (50.0%) were conclusive. The majority of reviews recognized the need for additional studies. In the field of gynaecological cancer, reviews are more likely to be conclusive when they include RCTs, as well as large numbers of patients. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    1999-07-01

    The aims of the study were to identify indicators of quality of nursing care from the perceptions of patients and nurses, and to determine the congruence between patients' and nurses' perceptions. The paper is presented in two parts. Part 1 includes the background and methods to the study and the findings from the comparison of patients' and nurses' perceptions. Part 2 describes the perceptions of patients and nurses, and the conclusions drawn from the study as a whole. Patients and nurses in hospital wards were interviewed using the critical incident technique. We grouped 4546 indicators of high and low quality nursing care generated from the interview transcripts into 316 subcategories, 68 categories and 31 themes. Congruence between patients' and nurses' perceptions of quality was high and significant, although there was some difference of emphasis.

    2004-01-01

    This monograph deals with assessment of radiological health effects of the Chernobyl accident for emergency workers (part 1) and the population of the contaminated areas in Russia (part 2). The Chernobyl emergency workers and people living in the contaminated areas of Russia received much lower doses than the population of Hiroshima and Nagasaki and it was unclear whether risks of radiation-induced cancers derived with the Japanese data could be extrapolated to the low dose range However, it was predicted as early as in 1990 that the thyroid cancer incidence might be increasing due to incorporated 131 irradiation. What conclusions can be drawn from regarding cancer incidence among emergency workers and residents of the contaminated areas in Russia and the role of the radiation factor on the basis of the registry data? Leukemia incidence. Leukemia incidence is known to be one of principal indications of radiation effects. The radiation risk for leukemias is 3-4 times higher that for solid cancers and its latent period is estimated to be 2-3 years after exposure. Results of the radiation epidemiological studies discussed in this book show that in the worst contaminated Bryansk region the leukemia incidence rate is not higher than in the country in general. Even though some evidence exists for the dose response relationship, the radiation risks appear to be not statistically significant. Since risks of leukemia are known to be higher for those who were children at exposure, long-term epidemiological studies need to be continued. The study of leukemias among emergency workers strongly suggest the existence of dose response relationship. In those who received external doses more than 0.15 Gy the leukemia incidence rate is two time higher and these emergency workers should be referred to as a group of increased radiation risk. Solid cancers. The obtained results provide no evidence to a radiation-induced increase in solid cancers among residents of the contaminated areas

    Full Text Available Deep understanding of human potential reproduction, presenting it as a continuous cycle and reflecting the continuity of generations, is significant for the formation of health and development of children. Today’s children will determine the future of Russian society. It is they who in 10–15 years will be a major part of the labor and creative population, a demographic base of the country. The research into children’s problems through the prism of socio-economic development helps identify targets of the state many-sided policy. The article presents results of the long-term medical sociological monitoring on the formation of child health carried out by the Institute of Socio-Economic Development of Territories of RAS with the support of the Vologda Oblast Healthcare Department since 1995. The special monitoring study of health dynamics in real time is unique not only for the Vologda Oblast, but for Russia as well. It reveals the transformation of a personality and the dependence of these changes on direct and indirect factors. The work’s feature is that it addresses an extremely important and wide range of issues: whether man was born healthy or not, if he/she is unhealthy, then why and why he/she was born unhealthy; whether his/her health after the birth is improving or deteriorating; if health is changing, what causes the changes. The 15 year observations disclose the dynamics of child health in the conditions of transformation processes taking place in the country. If the official statistics only records certain health trends, the monitoring results allow us to talk about them at a qualitatively new level. They reveal the underlying causes of demographic processes. The conclusion is, on the one hand, obvious and, on the other hand, it can not be neglected: economic stability and orderly development of the social sphere are critical for family well-being and child health. The reverse situation leads to the destruction of the family

    Industrial support of biomedical research may bias scientific conclusions, as demonstrated by recent analyses of pharmaceutical studies. However, this issue has not been systematically examined in the area of nutrition research. The purpose of this study is to characterize financial sponsorship of scientific articles addressing the health effects of three commonly consumed beverages, and to determine how sponsorship affects published conclusions. Medline searches of worldwide literature were used to identify three article types (interventional studies, observational studies, and scientific reviews) about soft drinks, juice, and milk published between 1 January, 1999 and 31 December, 2003. Financial sponsorship and article conclusions were classified by independent groups of coinvestigators. The relationship between sponsorship and conclusions was explored by exact tests and regression analyses, controlling for covariates. 206 articles were included in the study, of which 111 declared financial sponsorship. Of these, 22% had all industry funding, 47% had no industry funding, and 32% had mixed funding. Funding source was significantly related to conclusions when considering all article types (p = 0.037). For interventional studies, the proportion with unfavorable conclusions was 0% for all industry funding versus 37% for no industry funding (p = 0.009). The odds ratio of a favorable versus unfavorable conclusion was 7.61 (95% confidence interval 1.27 to 45.73), comparing articles with all industry funding to no industry funding. Industry funding of nutrition-related scientific articles may bias conclusions in favor of sponsors' products, with potentially significant implications for public health.

    Scientists have an ethical responsibility to assist non-scientists to understand their findings and expert opinions before they are used as decision-aids within the criminal justice system. The communication of scientific expert opinion to non-scientist audiences (e.g., police, lawyers, and judges) through expert reports is an important but under-researched issue. Readability statistics were used to assess 111 conclusions from a proficiency test in forensic glass analysis. The conclusions were written using an average of 23 words per sentence, and approximately half of the conclusions were expressed using the active voice. At an average Flesch-Kincaid Grade level of university undergraduate (Grade 13), and Flesch Reading Ease score of difficult (42), the conclusions were written at a level suitable for people with some tertiary education in science, suggesting that the intended non-scientist readers would find them difficult to read. To further analyse the readability of conclusions, descriptive features of text were used: text structure; sentence structure; vocabulary; elaboration; and coherence and unity. Descriptive analysis supported the finding that texts were written at a level difficult for non-scientists to read. Specific aspects of conclusions that may pose difficulties for non-scientists were located. Suggestions are included to assist scientists to write conclusions with increased readability for non-scientist readers, while retaining scientific integrity. In the next stage of research, the readability of expert reports in their entirety is to be explored. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    This document summarizes the conclusions of the European Council held in Barcelona (Spain) on March 15 and 16, 2002. Among the priority actions listed by the council figure the integration of energy, transportation and communication networks at the European scale. In particular, the council commits the Parliament and itself to start the final phase of opening of gas and electricity markets: free choice of a supplier, obligation of public utility, security of supplies, separation between transmission and distribution and between production and supply, non-discriminatory access of consumers and suppliers to networks with transparent tariffs, establishment of a regulatory agency in each member state, agreement for a tariffing system for the international electricity trades etc.. Concerning the sustainable development strategy of the European union, the council is pressing the member states for the completion of the national procedures of ratification of the Kyoto protocol. However, new measures need to be taken to develop technologies respectful for the environment, in particular in the domain of energy and transports. (J.S.)

Electrochemical characterisation of the PDEs, using different batches of HB grade pencils, is undertaken using several inner- and outer-sphere redox probes and is critically compared to screen-printed electrodes (SPEs. Proof-of-concept is demonstrated for the electrochemical sensing of dopamine and acetaminophen using PDEs, which are found to exhibit competitive limits of detection (3σ upon comparison to SPEs. Nonetheless, it is important to note that a clear lack of reproducibility was demonstrated when utilising these PDEs fabricated using the HB pencils from different batches. We also explore the suitability and feasibility of a pencil-drawn reference electrode compared to screen-printed alternatives, to see if one can draw the entire sensing platform. This article reports a critical assessment of these PDEs against that of its screen-printed competitors, questioning the overall feasibility of PDEs’ implementation as a sensing platform.

    The aim of this study was to investigate the hypothesis that chronic widespread pain, (CWP) drawn by patients on a body diagram, could be used as a screening tool for increased pain sensitization, psycho-social load, and utilization of pain management strategies. The triage questionnaires of 144 adults attending a chronic pain outpatients' clinic were audited and the percentage pain surface area (PPSA) drawn on their body diagrams was calculated using the "rule of nines" (RON) method for burns area assessment. Outcomes were measured using the painDETECT Questionnaire (PD-Q) and other indices and compared using a nonrandomized, case-control method. It was found that significantly more subjects with CWP (defined as a PPSA ≥ 20%) reported high (≥ 19) PD-Q scores (suggesting pain "sensitization" or neuropathic pain) (P = 0.0002), "severe" or "extremely severe" anxiety scores on the Depression, Anxiety and Stress Scale-21 Items Questionnaire (P = 0.0270), ≥ 5 psycho-social stressors (P = 0.0022), ≥ 5 significant life events (P = 0.0098), and used ≥ 7 pain management strategies (PMS) (P psycho-social load, and utilizing pain management resources. © 2014 World Institute of Pain.

    Microstructure evolution of a cold-drawn NiTi shape memory alloy wire was investigated by means of in-situ synchrotron high-energy X-ray diffraction during continuous heating. The cold-drawn wire contained amorphous regions and nano-crystalline domains in its microstructure. Pair distribution function analysis revealed that the amorphous regions underwent structural relaxation via atomic rearrangement when heated above 100 °C. The nano-crystalline domains were found to exhibit a strong cold work induced lattice strain anisotropy along 〈111〉, which coincides with the crystallographic fiber orientation of the domains along the wire axial direction. The lattice strain anisotropy systematically decreased upon heating above 200 °C, implying a structural recovery. Crystallization of the amorphous phase led to a broadening of the angular distribution of 〈111〉 preferential orientations of grains along the axial direction as relative to the original 〈111〉 axial fiber texture of the nanocrystalline domains produced by the severe cold wire drawing deformation.

    DIRECT-MAT (Dismantling and Recycling Techniques for road Materials) is a research project included in the 7{sup t}h Framework Programme of the EU, which counted with the participation of 20 partners from 15 different European countries. The Transport Research Centre of CEDEX (Spain) has been part of this project that began in January 2009. The aim of the DIRECT-MAT project has been to enable that national experience in the field of demolition and recycling of materials related to roads can be shared and disseminated among European countries for the benefit of all of them. In 2011 the paper the Direct-Mat Project: Dismantling and recycling techniques for road materials. Sharing knowledge and practices was published in the number 161 of Ingenieria Civil magazine. That paper consisted of an extensive description of the project, explaining in detail its structure, the status of the work in early 2011 and the conclusions drawn from the milestones (review of existing national documents). This paper is a continuation of the one previously published. This this article describes the work carried out since then and the collisions of the project. During this time, the main activities have been the compilation of several case studies and the developing of best practice guides. Regarding the results of the project, it is important to mention the database in which all the information gathered during the project is being uploads. Soon, it will have free online access. This database in perhaps the most remarkable results of the project, as it represents an invaluable reference tool for all the stake holders interested in the wide variety of recycling techniques that are being carried out today in Europe.

    We aimed to test any association between authors' conclusions and self-reported COI or funding sources in central nervous system (CNS) studies. A review was performed for CNS malignancy clinical trials published in the last 5 years. Two investigators independently classified study conclusions according to authors' endorsement of the experimental therapy. Statistical models were used to test for associations between positive conclusions and trials characteristics. From February 2010 to February 2015, 1256 articles were retrieved; 319 were considered eligible trials. Positive conclusions were reported in 56.8% of trials with industry-only, 55.6% with academia-only, 44.1% with academia and industry, 77.8% with none, and 76.4% with not described funding source (p = 0.011). Positive conclusions were reported in 60.4% of trials with unrelated COI, 60% with related COI, and 60% with no COI reported (p = 0.997). Factors that were significantly associated with the presence of positive conclusion included trials design (phase 1) [OR 11.64 (95 CI 4.66-29.09), p source [OR 2.45 (95 CI 1.22-5.22), p = 0.011]. In a multivariable regression model, all these factors remained significantly associated with trial's positive conclusion. Funding source and self-reported COI did not appear to influence the CNS trials conclusion. Funding source information and COI disclosure were under-reported in 14.1 and 17.2% of the CNS trials. Continued efforts are needed to increase rates of both COI and funding source reporting.

    The article touches upon building of a heart electrical axis position conclusion model using an artificial neural network. The input signals of the neural network are the values of deflections Q, R and S; and the output signal is the value of the heart electrical axis position. Training of the network is carried out by the error propagation method. The test results allow concluding that the created neural network makes a conclusion with a high degree of accuracy.

  9. A fallacious jar? The peculiar relation between descriptive premises and normative conclusions in neuroethics.

    2015-06-01

    Ethical questions have traditionally been approached through conceptual analysis. Inspired by the rapid advance of modern brain imaging techniques, however, some ethical questions appear in a new light. For example, hotly debated trolley dilemmas have recently been studied by psychologists and neuroscientists alike, arguing that their findings can support or debunk moral intuitions that underlie those dilemmas. Resulting from the wedding of philosophy and neuroscience, neuroethics has emerged as a novel interdisciplinary field that aims at drawing conclusive relationships between neuroscientific observations and normative ethics. A major goal of neuroethics is to derive normative ethical conclusions from the investigation of neural and psychological mechanisms underlying ethical theories, as well as moral judgments and intuitions. The focus of this article is to shed light on the structure and functioning of neuroethical arguments of this sort, and to reveal particular methodological challenges that lie concealed therein. We discuss the methodological problem of how one can--or, as the case may be, cannot--validly infer normative conclusions from neuroscientific observations. Moreover, we raise the issue of how preexisting normative ethical convictions threaten to invalidate the interpretation of neuroscientific data, and thus arrive at question-begging conclusions. Nonetheless, this is not to deny that current neuroethics rightly presumes that moral considerations about actual human lives demand empirically substantiated answers. Therefore, in conclusion, we offer some preliminary reflections on how the discussed methodological challenges can be met.

    According to Japan's basic policies of new growth strategy, it would be one option of the economic growth to increase exports of nuclear power plant system or its equipments. However, bilateral nuclear cooperation agreements are indispensable for business activities on nuclear power. Recently signature of agreement with Jordan, agreed conclusion negotiation with Vietnam and Korea, under negotiation with India and expected negotiation with Indonesia and Malaysia. Signed agreements with Russia and Kazakhstan will be coming into effect and contribute nuclear fuel supply at export of nuclear power system. This special article consists of four expert's papers titled as (1) necessity of conclusion negotiation of nuclear cooperation agreements with several countries simultaneously and in parallel, (2) Japan's nuclear cooperation in new era, (3) desirable acceleration of conclusion negotiation of nuclear cooperation agreements and (4) insurance of nuclear fuel supply fundamental for global business activities of Japan's nuclear industries-best choice to establish cooperative relations with US and Russia.

    This article analyzes a neat conjuring trick employed in bioethics, that is, the immediate conversion of a philosophical conclusion into a policy prescription, and compares it to the "grand leap of the whale up the Niagara Falls" mentioned by Benjamin Franklin. It is shown that there is no simple and easy way to achieve the conversion, by considering arguments falling under four headings: (1) reasonable disagreement about values and theories, (2) general jurisprudential arguments, (3) the differences between policymaking and philosophy, and (4) the messy world of implementation. The particular issue used to illustrate the difficulties in moving from philosophical conclusion to policy description is infanticide of healthy infants, but the analysis is general, and the conclusion that the immediate move to policy is illegitimate is quite general.

    A conclusive teleportation protocol of a d-dimensional two-particle unknown quantum state using three ddimensional particles in an arbitrary pure state is proposed. A sender teleports the unknown state conclusively to a receiver by using the positive operator valued measure(POVM) and introducing an ancillary qudit to perform the generalized Bell basis measurement. We calculate the optimal teleportation fidelity. We also discuss and analyse the reason why the information on the teleported state is lost in the course of the protocol.

    The results of level 1 PSA generate fluctuations due to the assumptions based on several engineering judgements set in the stages of PSA analysis. On the purpose of the investigation of uncertainties due to assumptions, three kinds of a standard problem, what we call benchmark exercise have been set. In this report, sensitivity studies (benchmark exercise) of sequence analyses are treated and conclusions are mentioned. The treatment of inter-system dependency would generate uncertainly of PSA. In addition, as a conclusion of the PSA benchmark exercise, several findings in the sequence analysis together with previous benchmark analyses in earlier INSS Journals are treated. (author)

Characterisations performed show the appearance and texture development during the reduction of section of the wire. The texture is mainly composed of the fiber // DN (DN // drawing axis (majority and the fiber // ND (minority whose acuity increases with deformation level. The wire was performed for the main components of the texture, ie the fiber and conventionally present in these materials. We will pay particular attention on the energy of the cube component {100} recrystallization that develops when the level of reduction is sufficient. There was also an increase in hardness and electrical resistivity along the applied deformation.

    In this study, a side-stream anaerobic fertilizer-drawn forward osmosis (FDFO) and ultrafiltration (UF) membrane bioreactor (MBR) hybrid system was proposed and operated for 55days. The FDFO performance was first investigated in terms of flux decline with various fertilizers draw solution. Flux decline was very severe with all fertilizers due to the absence of aeration and the sticky property of sludge. Flux recovery by physical cleaning varied significantly amongst tested fertilizers which seriously affected biofouling in FDFO via reverse salt flux (RSF). Besides, RSF had a significant impact on nutrient accumulation in the bioreactor. These results indicated that nutrient accumulation negatively influenced the anaerobic activity. To elucidate these phenomena, bacterial and archaeal community structures were analyzed by pyrosequencing. Results showed that bacterial community structure was affected by fertilizer properties with less impact on archaeal community structure, which resulted in a reduction in biogas production and an increase in nitrogen content.

    In order to dilute the harmful smoke and dust of the working surface in the production of the roadway in the mine shaft, the combination of mine local ventilation is often considered when conditions permitting. However there is no definite method to determine the distance between fan and working surface. Considering the concentration of smoke, the size of working face, the ventilation time, the wind speed of the working face and the principle of suction volume, this paper analyzes the long - drawn short - pressure type of the ventilation scheme, and presents an optimal algorithm for the distance between the exhaust ventilator and the working face:{{L}}{{o}}=\\frac{{({{{v}}}{{f}}{{t}})}{{Z}}{{{S}}}{{o}}\\frac{\\exists }{{{z}}{{β }}}}{3.398{{{S}}}W\\frac{1}{{{z}}{{A}}}}. Then this paperpresentsa reference distance for different wind speed requirements of a project.

  19. Dependence of hydrogen-induced lattice defects and hydrogen embrittlement of cold-drawn pearlitic steels on hydrogen trap state, temperature, strain rate and hydrogen content

    Doshida, Tomoki; Takai, Kenichi

    2014-01-01

    The effects of the hydrogen state, temperature, strain rate and hydrogen content on hydrogen embrittlement susceptibility and hydrogen-induced lattice defects were evaluated for cold-drawn pearlitic steel that absorbed hydrogen in two trapping states. Firstly, tensile tests were carried out under various conditions to evaluate hydrogen embrittlement susceptibility. The results showed that peak 2 hydrogen, desorbed at temperatures above 200 °C as determined by thermal desorption analysis (TDA), had no significant effect on hydrogen embrittlement susceptibility. In contrast, hydrogen embrittlement susceptibility increased in the presence of peak 1 hydrogen, desorbed from room temperature to 200 °C as determined by TDA, at temperatures higher than −30 °C, at lower strain rates and with higher hydrogen content. Next, the same effects on hydrogen-induced lattice defects were also evaluated by TDA using hydrogen as a probe. Peak 2 hydrogen showed no significant effect on either hydrogen-induced lattice defects or hydrogen embrittlement susceptibility. It was found that hydrogen-induced lattice defects formed under the conditions where hydrogen embrittlement susceptibility increased. This relationship indicates that hydrogen embrittlement susceptibility was higher under the conditions where the formation of hydrogen-induced lattice defects tended to be enhanced. Since hydrogen-induced lattice defects formed by the interaction between hydrogen and strain were annihilated by annealing at a temperature of 200 °C, they were presumably vacancies or vacancy clusters. One of the common atomic-level changes that occur in cold-drawn pearlitic steel showing higher hydrogen embrittlement susceptibility is the formation of vacancies and vacancy clusters

    Understanding how people with delusions arrive at false conclusions is central to the refinement of cognitive behavioural interventions. Making hasty decisions based on limited data ('jumping to conclusions', JTC) is one potential causal mechanism, but reasoning errors may also result from other processes. In this study, we investigated the correlates of reasoning errors under differing task conditions in 204 participants with schizophrenia spectrum psychosis who completed three probabilistic reasoning tasks. Psychotic symptoms, affect, and IQ were also evaluated. We found that hasty decision makers were more likely to draw false conclusions, but only 37% of their reasoning errors were consistent with the limited data they had gathered. The remainder directly contradicted all the presented evidence. Reasoning errors showed task-dependent associations with IQ, affect, and psychotic symptoms. We conclude that limited data-gathering contributes to false conclusions but is not the only mechanism involved. Delusions may also be maintained by a tendency to disregard evidence. Low IQ and emotional biases may contribute to reasoning errors in more complex situations. Cognitive strategies to reduce reasoning errors should therefore extend beyond encouragement to gather more data, and incorporate interventions focused directly on these difficulties.

    An article in NASA Tech Briefs describing a vacuum bagging process for forming composite parts helped a small Oklahoma Company to improve its manufacturing process. President of Performance Extremes, Larry Ortega, and his partners make motorcycle parts from carbon/epoxy to reduce weight. Using vacuum bags, parts have a better surface and fewer voids inside. When heat used in the vacuum bag process caused deformation upon cooling, a solution found in another tech brief solved the problem. A metal plate inside the vacuum bag made for more even heat transfer. A third article described a simple procedure for repairing loose connector pins, which the company has also utilized.

    2014-01-01

    That delusional and delusion-prone individuals "jump to conclusions" on probabilistic reasoning tasks is a key finding in cognitive neuropsychiatry. Here we focused on a less frequently investigated aspect of "jumping to conclusions" (JTC): certainty judgments. We incorporated rigorous procedures from experimental economics to eliminate potential confounds of miscomprehension and motivation and systematically investigated the effect of incentives on task performance. Low- and high-delusion-prone participants (n = 109) completed a series of computerised trials; on each trial, they were shown a black or a white fish, caught from one of the two lakes containing fish of both colours in complementary ratios. In the betting condition, participants were given £4 to distribute over the two lakes as they wished; in the control condition, participants simply provided an estimate of how probable each lake was. Deviations from Bayesian probabilities were investigated. Whereas high-delusion-prone participants in both the control and betting conditions underestimated the Bayesian probabilities (i.e. were conservative), low-delusion-prone participants in the control condition underestimated but those in the betting condition provided accurate estimates. In the control condition, there was a trend for high-delusion-prone participants to give higher estimates than low-delusion-prone participants, which is consistent with previous reports of "jumping to conclusions" in delusion-prone participants. However, our findings in the betting condition, where high-delusion-prone participants provided lower estimates than low-delusion-prone participants (who were accurate), are inconsistent with the jumping-to-conclusions effect in both a relative and an absolute sense. Our findings highlight the key role of task incentives and underscore the importance of comparing the responses of delusion-prone participants to an objective rational standard as well as to the responses of non

It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event-related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual process theories of be...

    T. Connolly, L. D. Ordo;aan;atez, and R. Coughlan (1997, Organizational Behavior and Human Decision Processes, 70, 73-85) argued, on the basis of 5 experiments, that regret need not be related to a sense of responsibility for the regretted outcome. We (M. Zeelenberg, W. W. van Dijk, & A. S. R. Manstead, 1998, Organizational Behavior and Human Decision Processes, 74, 254-272) showed in 2 experiments that this conclusion was premature, because it was based on an indirect measure of regret (i.e., overall happiness with the decision outcome). When regret was directly measured, the predicted effects of responsibility were found. L. D. Ordo;aan;atez and T. Connolly (2000, Organizational Behavior and Human Decision Processes, 81, 132-142) replicated our findings in 2 experiments. Based on their findings they arrived at 4 conclusions. In this rejoinder we first discuss Ordóñez and Connolly's new studies and we then discuss the validity of their 4 conclusions. Copyright 2000 Academic Press.

    Understanding how people with delusions arrive at false conclusions is central to the refinement of cognitive behavioural interventions. Making hasty decisions based on limited data (‘jumping to conclusions’, JTC) is one potential causal mechanism, but reasoning errors may also result from other processes. In this study, we investigated the correlates of reasoning errors under differing task conditions in 204 participants with schizophrenia spectrum psychosis who completed three probabilistic reasoning tasks. Psychotic symptoms, affect, and IQ were also evaluated. We found that hasty decision makers were more likely to draw false conclusions, but only 37% of their reasoning errors were consistent with the limited data they had gathered. The remainder directly contradicted all the presented evidence. Reasoning errors showed task-dependent associations with IQ, affect, and psychotic symptoms. We conclude that limited data-gathering contributes to false conclusions but is not the only mechanism involved. Delusions may also be maintained by a tendency to disregard evidence. Low IQ and emotional biases may contribute to reasoning errors in more complex situations. Cognitive strategies to reduce reasoning errors should therefore extend beyond encouragement to gather more data, and incorporate interventions focused directly on these difficulties. PMID:24958065

    2000-03-01

    Following a recommendation of the OECD Workshop on the Chemistry of Iodine in Reactor Safety held in Wuerenlingen (Switzerland) in June 1996 [Summary and Conclusions of the Workshop, Report NEA/CSNI/R(96)7], the CSNI decided to sponsor a Workshop on Iodine Aspects of Severe Accident Management, and their planned or effective implementation. The starting point for this conclusion was the realization that the consolidation of the accumulated iodine chemistry knowledge into accident management guidelines and procedures remained, to a large extent, to be done. The purpose of the meeting was therefore to help build a bridge between iodine research and the application of its results in nuclear power plants, with particular emphasis on severe accident management. Specifically, the Workshop was expected to answer the following questions: - what is the role of iodine in severe accident management? - what are the needs of the utilities? - how can research fulfill these needs? The Workshop was organized in Vantaa (Helsinki), Finland, from 18 to 20 May 1999, in collaboration with Fortum Engineering Ltd. It was attended by forty-six specialists representing fifteen Member countries and the European Commission. Twenty-eight papers were presented. These included four utility papers, representing the views of Electricite de France (EDF), Teollisuuden Voima Oy and Fortum Engineering Ltd (Finland), the Nuclear Energy Institute (USA), and Japanese utilities. The papers were presented in five sessions: - iodine speciation; - organic compound control; - iodine control; - modeling; - iodine management; A sixth session was devoted to a general discussion on iodine management under severe accident conditions. This report summarizes the content of the papers and the conclusions of the workshop

    The concrete of the bored piles of Angra 2 was submitted to a deep control, so more than five thousand core samples were analyzed to verify the quality of the concrete. Based on these samples and using statistics regression theory some conclusions could be done. It was analyzed the dependence of the concrete strength upon the depth of the pile. Also based on these samples some probability distribution functions that could simulate the concrete strength were studied applying the Kolmogorov - Smirnov fitness test. Finally, a method for evaluating a confidence interval of one of the probability function (Weibull distribution) was developed adopting the Monte Carlo simulation technique. (Author) [pt

    A sampling system was assembled for field 222 Rn activity concentration measurements in ground waters. The system consists of a sampling flask that prevents the contact between the water sample and the atmosphere and a closed line for radon extraction from water. The system, its operation and calibration, are described in full detail, as well as, the conversion of the measured alpha counting rates in activity concentrations. The assembled system was used in 222 Rn activity concentrations measurements in ground waters drawn from two wells drilled in the Amparo Complex metamorphic rocks. The wells are located at the urban area of the city of Amparo and are exploited for public use water. One well, named Vale Verde, is 56 meters deep and crosses 18 meters of soil, 26 meters of quartz rich gneiss and 12 meters of biotite-gneiss. The other well, named Seabra, is 117 meters deep, crosses 28 meters of soil and weathered rocks and ends in granite-gneiss. The mean activity concentrations for the year long observation were (377 +- 25) Bq/dm 3 , for Seabra well, and (1282 +- 57) Bq/dm3, for the Vale Verde well. The 222 Rn activity concentrations fall in the activity concentration range reported in the literature for similar geology areas and are larger than the concentrations found neighboring areas of the same metamorphic Complex. The seasonal activity concentration variations seem to correlate with rain fall variations in the study area. (author)

    Many investigators consider children’s drawings to be an important test in the evaluation of stress and anxiety, but few studies have examined the reliability and validity of indicators of emotional distress in children’s projective drawings. In this report, we describe screening tests in children coming to the Friuli Venezia Giulia region in Northeastern Italy from non-European Union regions and suspected to have celiac disease, the problems involved in diagnosis of the disease, and the “drawn double nostalgia” of Romanian children for both Italian food and traditional Romanian foods. Of 3150 Western European cases, we found 712 with positive antibodies for IgA/IgG antitransglutaminase, 174 with a positive antiendomysium antibody confirmation test, and 20 with an IgA deficit. Of the children examined, 93% were children native to Western Europe, 4% were immigrants from Eastern Europe, and 1.6% originated from Africa. Among these, four Romanian children with celiac disease brought in their drawings, as requested in a hospital questionnaire. The prevalence of celiac disease is destined to increase among immigrants. Economic problems are common, and the twin nostalgia of immigrant children for foods and tastes that are “cozonac” (from the native country) and “panettone” (Italian cake flavor) represents a problem that will be difficult to resolve. Only some children’s hospitals in Italy, ie, Burlo Garofolo and Gaslini, public and private foundations, or volunteer associations would be able to deal with this problem. PMID:21753894

    The present investigations were undertaken with the aim to understand, to what extent variations of the tube fabrication parameters and slight modifications in the chemical composition might influence the swelling behaviour of Type 1.4970 stainless steel. The parameters varied were: Variations in the manufacturing parameters for coldworked tubes (type and degree of drawing, solution-annealing temperature and thermomechanical treatments), and variations in minor elements (C, Ti, Mo) within the specified range of chemical composition. In addition, the Si-content and the Ti/C ratio - the so-called stabilization - were changed within a broader range. The samples were irradiated with 46 MeV-Ni-ions to 64 dpa at 575 0 C and swelling as well as austenite stability, formation of precipitates and other microstructural changes were investigated by TEM. Though the austenite was stable under irradiation with respect to ferrite/martensite-transformation, the cold-drawn alloys showed a tendency to recrystallize during irradiation and exhibited lean precipitation. With respect to swelling, the only parameter that substantially reduced it, was the high Si addition; otherwise the alloys were practically insensitive to changes in the investigated parameters. These results are discussed in terms of the radiation-induced recrystallization and the high Si-effect, both of which are found to be beneficial in reducing swelling. (orig.)

    Catheter-related bloodstream infections (CRBSIs) remain a leading cause of healthcare-associated infections in preterm infants. Rapid and accurate methods for the diagnosis of CRBSIs are needed in order to implement timely and appropriate treatment. A retrospective study was conducted during a 7-year period (2005-2012) in the neonatal intensive care unit of the University Hospital Erasme to assess the value of Gram stain on catheter-drawn blood samples (CDBS) to predict CRBSIs. Both peripheral samples and CDBS were obtained from neonates with clinically suspected CRBSI. Gram stain, automated culture and quantitative cultures on blood agar plates were performed for each sample. The paired quantitative blood culture was used as the standard to define CRBSI. Out of 397 episodes of suspected CRBSIs, 35 were confirmed by a positive ratio of quantitative culture (>5) or a colony count of CDBS culture >100 colony-forming units (CFU)/mL. All but two of the 30 patients who had a CDBS with a positive Gram stain were confirmed as having a CRBSI. Seven patients who had a CDBS with a negative Gram stain were diagnosed as CRBSI. The sensitivity, specificity, positive predictive value and negative predictive value of Gram stain on CDBS were 80, 99.4, 93.3 and 98.1 %, respectively. Gram staining on CDBS is a viable method for rapidly (<1 h) detecting CRBSI without catheter withdrawal.

    Gradual environmental degradation, shrinking of non-renewable resources, and lower quality of life are directly or indirectly arising from snowballing consumption. These unfavorable processes concern increasingly textile and clothing sector and are increasingly being felt in Visegrad Region (V4). The objective of the article was to access current consumption patterns in V4 countries, identify the factors that influence those patterns and finally to draw the conclusions for more sustainable consumption and production models as well as to make a comparative analysis of the results across V4 countries. A consumer survey was conducted to examine V4 citizens’ attitudes and behaviors in the context of sustainable consumption. To ensure sample size and comparability across countries 2000 randomly-selected V4 citizens, aged 18 and over, were interviewed. To analyze the supply side of the market and legal framework, the desk research was used. The results allowed to give some guidelines for the joint V4 strategy for solving ecological and social problems of V4 countries as well as the conclusions for textile and clothing sector.

    Sexual child abuse, comprises of indecency attitudes and physical misbehaviours, directed towards children are dominated by rape. The objective of our study was to assess in sexual child abuse the relation between the conclusion of medical certificates and court decision. It is a retrospective study carried out from 1994 to 1998 on the clerk's office correctional repertories in Dakar regional court. An overall number of 79 cases of child abuse were collected in 5 years period. Children under 18 years old of of both sex, were concerned. Data found were correlated with a review of requisition cases received by the of gynaecology and obstetrics clinic of Aristide Dantec Hospital. This facilitates the establishement of the relationship between the offences and the pronounced sanctions, as well as the initial medical certificate and these sanctions. The sanctions were severe whenever rape had been retained. Some cases were disqualified in indecent assault and were judged as such. The judge decision, which follow the medical certificate conclusions in 11 cases out of 14 shows the importance and reliability of this medical document. All files reviewed at the medical and legal level were incomplete. The difficulty of the materiality of the rape and the psychological consequences in the long run and especially HIV infection should invite to a multidisciplinary, specialized and organized management of sexual child abuse. This study has shown the importance of a correct and complete drafting of the medical certificate, to enable the establishment by the judge the materiality of the facts.

    As the 21st century progresses, new nuclear facilities and the expansion of nuclear activities into new countries will require the International Atomic Energy Agency (IAEA) to place a higher reliance on attaining and maintaining a Continuity of Knowledge (CoK) of its safeguards information than is currently practiced. Additionally, a conceptual view of where and how CoK can be applied will need to evolve to support improved efficiency and efficacy of drawing a safeguards conclusion for each Member State. The ability to draw a safeguards conclusion for a Member State will be predicated on the confidence that CoK has been attained and subsequently maintained with respect to the data and information streams used by the IAEA. This confidence can be described as a function of factors such as elapsed time since the measurement, surveillance of attributes, authentication of information, historic knowledge of potential system failures, and the number and type of data collections. A set of general scenarios are further described for determining what is required to attain CoK and whether CoK has been maintained. A high-level analysis of example scenarios is presented to identify failures or gaps that could cause a loss of CoK. Potential areas for technological research and development are discussed for the next generation of CoK tools.

  16. Analysing and exemplifying forensic conclusion criteria in terms of Bayesian decision theory.

    Science.gov (United States)

    Biedermann, A; Bozza, S; Taroni, F

    2018-03-01

    There is ongoing discussion in forensic science and the law about the nature of the conclusions reached based on scientific evidence, and on how such conclusions - and conclusion criteria - may be justified by rational argument. Examples, among others, are encountered in fields such as fingermarks (e.g., 'this fingermark comes from Mr. A's left thumb'), handwriting examinations (e.g., 'the questioned signature is that of Mr. A'), kinship analyses (e.g., 'Mr. A is the father of child C') or anthropology (e.g., 'these are human remains'). Considerable developments using formal methods of reasoning based on, for example (Bayesian) decision theory, are available in literature, but currently such reference principles are not explicitly used in operational forensic reporting and ensuing decision-making. Moreover, applied examples, illustrating the principles, are scarce. A potential consequence of this in practical proceedings, and hence a cause of concern, is that underlying ingredients of decision criteria (such as losses quantifying the undesirability of adverse decision consequences), are not properly dealt with. There is merit, thus, in pursuing the study and discussion of practical examples, demonstrating that formal decision-theoretic principles are not merely conceptual considerations. Actually, these principles can be shown to underpin practical decision-making procedures and existing legal decision criteria, though often not explicitly apparent as such. In this paper, we will present such examples and discuss their properties from a Bayesian decision-theoretic perspective. We will argue that these are essential concepts for an informed discourse on decision-making across forensic disciplines and the development of a coherent view on this topic. We will also emphasize that these principles are of normative nature in the sense that they provide standards against which actual judgment and decision-making may be compared. Most importantly, these standards are

    International Nuclear Information System (INIS)

    1986-06-01

    This report presents the findings, conclusions and recommendations derived from activities performed under Phase I of the NRC Maintenance and Surveillance Program (MSP). Findings are based on trends and patterns derived from operational data compiled by the NRC for the period 1980 through 1985, site surveys conducted at eight plants, and questionnaires administered to NRC Resident Inspectors to characterize nuclear power plant maintenance programs and practices. These activities have shown that plant maintenance programs and practices are highly variable from plant-to-plant and are currently undergoing major changes. While measured plant performance has improved overall since 1980, the maintenance-related contribution to reportable events and challenges to safety systems remains high and is increasing by some measures. The findings of Phase I of the MSP confirmed a number of problems in nuclear power plant maintenance which warrant further NRC and industry attention

    Teollisuuden Voima Oy (TVO) participated the international cooperation project INTRAVAL and VTT Energy acted as a project team. The Finnish participation focused on flow and transport in crystalline fractured rock and six test cases out of thirteen were tackled. The experimental results were evaluated mainly by means of analytical transport models. The report presents a short review of the experience obtained in the course of the project. It concentrates on the issues revealed in the discussions and analyses of the six test cases in which the TVO/VTT team actively participated but some of the conclusions are even more general in nature. Some suggestions are made for future experimental and theoretical work in the field of geosphere. (15 refs., 2 tabs.)

    In this letter, we present scanning electron microscopy (SEM) results that confirm in a direct way our earlier explanation of an abrupt coagulation event as the cause for the void hiccup. In a recent paper, we reported on the fast and interrupted expansion of voids in a reactive dusty argon–acetylene plasma. The voids appeared one after the other, each showing a peculiar, though reproducible, behavior of successive periods of fast expansion, abrupt contraction, and continued expansion. The abrupt contraction was termed “hiccup” and was related to collective coagulation of a new generation of nanoparticles growing in the void using relatively indirect methods: electron density measurements and optical emission spectroscopy. In this letter, we present conclusive evidence using SEM of particles collected at different moments in time spanning several growth cycles, which enables us to follow the nanoparticle formation process in great detail.

    The analysis of Proxima Centauri’s radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun’s nearest star once every 11.2 days. Although the a priori probability that Proxima b transits its parent star is just 1.5%, the potential impact of such a discovery would be considerable. Independent of recent radial velocity efforts, we observed Proxima Centauri for 12.5 days in 2014 and 31 days in 2015 with the Microwave and Oscillations of Stars space telescope. We report here that we cannot make a compelling case that Proxima b transits in our precise photometric time series. Imposing an informative prior on the period and phase, we do detect a candidate signal with the expected depth. However, perturbing the phase prior across 100 evenly spaced intervals reveals one strong false positive and one weaker instance. We estimate a false-positive rate of at least a few percent and a much higher false-negative rate of 20%–40%, likely caused by the very high flare rate of Proxima Centauri. Comparing our candidate signal to HATSouth ground-based photometry reveals that the signal is somewhat, but not conclusively, disfavored (1 σ –2 σ ), leading us to argue that the signal is most likely spurious. We expect that infrared photometric follow-up could more conclusively test the existence of this candidate signal, owing to the suppression of flare activity and the impressive infrared brightness of the parent star.

    The Dietary Guidelines for Americans (DGA) is published every 5 y jointly by the Department of Health and Human Services (HHS) and the USDA and provides a framework for US-based food and nutrition programs, health promotion and disease prevention initiatives, and research priorities. Summarized in this report are the methods, major conclusions, and recommendations of the Scientific Report of the 2015 US Dietary Guidelines Advisory Committee (DGAC). Early in the process, the DGAC developed a conceptual model and formulated questions to examine nutritional risk and determinants and impact of dietary patterns in relation to numerous health outcomes among individuals aged ≥2 y. As detailed in the report, an expansive, transparent, and comprehensive process was used to address each question, with multiple opportunities for public input included. Consensus was reached on all DGAC's findings, including each conclusion and recommendation, and the entire report. When research questions were answered by original systematic literature reviews and/or with existing, high-quality expert reports, the quality and strength of the evidence was formally graded. The report was organized around the following 5 themes: 1) food and nutrient intakes and health: current status and trends; 2) dietary patterns, foods and nutrients, and health outcomes; 3) diet and physical activity behavior change; 4) food and physical activity environments; and 5) food sustainability and food safety. The following 3 cross-cutting topics were addressed: 1) sodium, 2) saturated fat, and 3) added sugars. Physical activity recommendations from recent expert reports were endorsed. The overall quality of the American diet was assessed to identify overconsumed and underconsumed nutrients of public health concern. Common food characteristics of healthy dietary patterns were determined. Features of effective interventions to change individual and population diet and physical activity behaviors in clinical, public

    The second OECD Specialist Meeting on operator aids for severe accident management (SAMOA-2) was held in Lyon, France (1997), and was attended by 33 specialists representing ten OECD member countries. As for SAMOA-1, the scope of SAMOA-2 was limited to operator aids for accident management which were in operation or could be soon. The meeting concentrated on the management of accidents beyond the design basis, including tools which might be extended from the design basis range into the severe accident area. Relevant simulation tools for operator training were also part of the scope of the meeting. 20 papers were presented; there were two demonstrations of computerized systems (the ATLAS analysis simulator developed by GRS, and EDF's 'Simulateur Post Accidentels' (SIPA). The three sessions dealt with operator aids for control rooms, operator aids for technical support centres, and simulation tools for operator training. The various papers for each session are summarized

    In Germany model tests have been performed for the utilization of a resisting type barrier instead of an energy absorbing type barrier, the latter used in nuclear merchant ships up to now only. After reviewing the model technique the results of nine tests with the new barrier are discussed. Calculations performed to the newly raised questions of the shock accelerations of the reactor plant and of possible overstressing of the hull are reported. The new design has many advantages with respect to safety and to the arrangement of a reactor plant in a ship too. Some questions partly remain unanswered at the moment concerning oblique collisions to the ends of the barrier and the possible effects of bulk cargo in holds close to the bow in striking ships of smaller size

    Drawing is commonly used in forensic and clinical interviews with children. In these interviews, children are often allowed to draw without specific instructions about the purpose of the drawing materials. Here, we examined whether this practice influenced the accuracy of children's reports. Seventy-four 5- and 6-year-old children were interviewed one to two days after they took part in an interactive event. Some children were given drawing materials to use during the interview. Of these children, some were instructed to draw about the event, and some were given no additional instructions at all. Children who were instructed to draw about the event, or who were interviewed without drawing, made few errors. In contrast, children who drew without being given specific instructions reported more errors that were associated with both confabulation and fantasy. We conclude that, to maximise accuracy during interviews involving drawing, children should be directed to draw specifically about the interview topic.

    Radiocesium ({sup 137}Cs) deposited after the Chernobyl nuclear disaster in 1986, still persist in forest ecosystems in parts of Sweden at relatively high concentrations. In the forest, radiocaesium is assumed to be reversibly bound to the soil, which facilitates its uptake by plant roots and fungal mycelia thus making it available, as fodder, to wild animals. Even today this leads to contaminated meat from moose (Alces alces) and other game species. Around 100 000 moose, approximately 1/3 of the whole population, are shot each year in Sweden which makes moose the main source of consumed game meat. Hence understanding the long-term behavior of radiocaesium in forest ecosystems is important for the evaluation of future potential health risks to consumers. The two municipalities of Heby and Uppsala, in east-central Sweden, experienced relatively large deposition in 1986 (5 - 100 kBq/m{sup 2}). Monitoring of the {sup 137}Cs activity concentrations in meat from moose hunted in these areas was initiated already in autumn 1986 and is still continuing. Muscle samples from front leg of the slaughtered moose are received from local hunters during the hunting season and more than 3500 samples have been collected during the years. The samples are adjoined with a sampling protocol containing information on estimated age, sex and weight, as well as where and when each moose was shot. Gamma spectrometry of the {sup 137}Cs- activities is performed on fresh or frozen moose muscle samples using HPGe detectors. The main part of all the samples analyzed since 1986 are from the northern part of Heby municipality. This study area covers approximately 400 km{sup 2} and received a mean ground deposition of approximately 35 kBq/m{sup 2} of {sup 137}Cs in 1986. The area is dominated by managed coniferous forests, but also includes large parts of agricultural land. A database of > 3 500 moose samples collected from hunts between 1986 and 2010 was used in this study. The results of the

    Metals have rapidly accumulated in the anthroposphere, especially in urban areas, indicating possible environmental and resource problems. Here, Stockholm City was chosen for a case study of urban metal flows, i.e. metal inflow to, metals in the stock of,and metal outflow from the anthroposphere to the biosphere. The metal stock of Stockholm is large and still growing. The large amounts of metals in the solid waste fraction totally dominate the outflow from the city. For major parts of the stock, the emissions from goods in use are negligible. There are, however,goods applications corresponding to significant emissions: e.g. the traffic sector (Cu, Zn, Cr, Ni, Pb), the tapwater system (Cu), roofs/fronts or other metal surfaces (Cu, Zn). Today's known metal flows from the anthroposphere of Stockholm to the biosphere and sewage sludge are quantitatively dominated by Zn(34 ton y -1 ) and Cu (14 ton y -1 ). Historical and present emissions have resulted in high metal concentrations in sediments (especially Cd, Hg and Pb, but also Cu and Zn), groundwater (Cu, Hg) and in soils (Hg, Cu, Pb). At present the annual median concentrations are below the Swedish limits for metals in sewage sludge, even if the safety margins are small for Cd, Hg and to some extent Cu. The flows of Cu and Zn to Stockholm soils are high with a significant accumulation indicating an environmental impact in a longer time perspective.High levels of metals in surface sediments in the water environments reflects an ongoing input where these metals are transported from known (Cu, Zn) and or partly unknown (Cd, Hg, Pb) sources. In future urban areas, monitoring of metal flows must be performed both in the anthroposphere and the biospherein order to have a pro active approach to urban environmental problems and to get prompt answers to measures taken

    The reference design for the underground facilities at the Waste Isolation Pilot Plant was developed using the best criteria available at initiation of the detailed design effort. These design criteria are contained in the US Department of Energy document titled Design Criteria, Waste Isolation Pilot Plant (WIPP). Revised Mission Concept-IIA (RMC-IIA), Rev. 4, dated February 1984. The validation process described in the Design Validation Final Report has resulted in validation of the reference design of the underground openings based on these criteria. Future changes may necessitate modification of the Design Criteria document and/or the reference design. Validation of the reference design as presented in this report permits the consideration of future design or design criteria modifications necessitated by these changes or by experience gained at the WIPP. Any future modifications to the design criteria and/or the reference design will be governed by a DOE Standard Operation Procedure (SOP) covering underground design changes. This procedure will explain the process to be followed in describing, evaluating and approving the change.

In this report, we describe screening tests in children coming to the Friuli Venezia Giulia region in Northeastern Italy from non-European Union regions and suspected to have celiac disease, the problems involved in diagnosis of the disease, and the “drawn double nostalgia” of Romanian children for both Italian food and traditional Romanian foods. Of 3150 Western European cases, we found 712 with positive antibodies for IgA/IgG antitransglutaminase, 174 with a positive antiendomysium antibody confirmation test, and 20 with an IgA deficit. Of the children examined, 93% were children native to Western Europe, 4% were immigrants from Eastern Europe, and 1.6% originated from Africa. Among these, four Romanian children with celiac disease brought in their drawings, as requested in a hospital questionnaire. The prevalence of celiac disease is destined to increase among immigrants. Economic problems are common, and the twin nostalgia of immigrant children for foods and tastes that are “cozonac” (from the native country and “panettone” (Italian cake flavor represents a problem that will be difficult to resolve. Only some children's hospitals in Italy, ie, Burlo Garofolo and Gaslini, public and private foundations, or volunteer associations would be able to deal with this problem.Keywords: drawing, nostalgia, immigration, celiac disease, food, children

    In the spring of 1994 an OECD Workshop on Large Pool Heat transfer was held in Grenoble. The scope of this workshop was the investigation of (1) molten pool heat transfer, (2) heat transfer to the surrounding water, and (3) the feasibility of in-vessel core debris cooling through external cooling of the vessel. Since this time, experimental test series have been completed (e.g., COPO, ULPU, CORVIS) and new experimental programs (e.g., BALI, SONATA, RASPLAV, debris and gap heat transfer) have been established to consolidate and expand the data base for further model development and to improve the understanding of in-vessel debris retention and coolability in a nuclear power plant. Discussions within the CSNI's PWG-2 and the Task Group on Degraded Core Cooling (TG-DCC) have led to the conclusion that the time was ripe for organizing a new international Workshop with the objectives: - to review the results of experimental research that has been conducted in this area; - to exchange information on the results of member countries experiments and model development on in-vessel core debris retention and coolability; - to discuss areas where additional experimental research is needed in order to provide an adequate data base for analytical model development for core debris retention and coolability. The scope of this workshop was limited to the phenomena connected to in-vessel core debris retention and coolability and did not include steam explosion and fission product issues. The workshop was structured into the following sessions: Key note papers; Experiments and model development; Debris bed heat transfer; Corium properties, molten pool convection and crust formation; Gap formation and gap cooling; Creep behaviour of reactor pressure vessel lower head; Ex-vessel boiling and critical heat flux phenomena; Scaling to reactor severe accident conditions and reactor applications. Compared to the previous workshop held in Grenoble in 1994, large progress has been made in the

    This letter gives a brief discussion of the possibilities of inducing nuclear effects by carrying out only chemical reactions. Undoubtedly, this interest is a result of the still unresolved problem of 'cold fusion,' and some colleagues tend to see a clear connection, and even an extension of the studies, between cold fusion and the alleged chemical transmutation of elements. While we have already published thorough reports (negative so far) of our studies with regard to the claimed increase of gamma-ray emission and beta decay after burning of a mixture of chemicals, this letter informs the Fusion Technology readership of an experimental curiosity that is encountered during similar studies that initially led us to an erroneous conclusion. As in previous studies, we compared certain radiochemical properties of a mixture of chemicals before and after a chemical reaction (burning). Under discussion here is a peak that we observed in the range of 412 keV in the gamma spectrum in one of the burned samples after neutron activating it for 3 min at 1 kW. This peak was ostensibly not present in the same sample unburned. 4 refs., 2 figs

    The objective of this study was to determine why different criteria for response to treatment of bacterial vaginosis (BV) led to markedly different conclusions about treatment efficacy in a randomized trial comparing metronidazole gel versus metronidazole/nystatin ovules. We compared the impact of two treatment regimens on individual components of Amsel and Nugent criteria at follow-up visits 14, 42, and 104 days after initiating treatment. Compared with gel, ovules more effectively eliminated amines, clue cells, and Gardnerella, Prevotella, or Mobiluncus morphotypes from vaginal fluid, thus achieving cure based on "usual" criteria (absence of BV by Amsel or Nugent criteria), but did not more effectively restore Lactobacillus morphotypes or lower vaginal pH, thus not meeting Federal Drug Administration (FDA) criteria for cure. Because early vaginal recolonization by lactobacilli was poor after both gel and ovules, FDA draft criteria for cure missed marked differences in treatment efficacies against Gardnerella, clue cells, and amines. Cure defined more "usually" may give more useful information.

    A symbolic encoding scheme, based on the ordinal relation between the amplitude of neighboring values of a given data sequence, should be implemented before estimating the permutation entropy. Consequently, equalities in the analyzed signal, i.e. repeated equal values, deserve special attention and treatment. In this work, we carefully study the effect that the presence of equalities has on permutation entropy estimated values when these ties are symbolized, as it is commonly done, according to their order of appearance. On the one hand, the analysis of computer-generated time series is initially developed to understand the incidence of repeated values on permutation entropy estimations in controlled scenarios. The presence of temporal correlations is erroneously concluded when true pseudorandom time series with low amplitude resolutions are considered. On the other hand, the analysis of real-world data is included to illustrate how the presence of a significant number of equal values can give rise to false conclusions regarding the underlying temporal structures in practical contexts. - Highlights: • Impact of repeated values in a signal when estimating permutation entropy is studied. • Numerical and experimental tests are included for characterizing this limitation. • Non-negligible temporal correlations can be spuriously concluded by repeated values. • Data digitized with low amplitude resolutions could be especially affected. • Analysis with shuffled realizations can help to overcome this limitation.

    2003-01-01

    Assessment of the impact of Aviation Resource Management Programs on aviation culture and performance has compelled a considerable body of research (Taylor & Robertson, 1995; Taylor, 1998; Taylor & Patankar, 2001). In recent years new methods have been applied to the problem of maintenance error precipitated by factors such as the need for self-assessment of communication and trust. The present study - 2002 -- is an extension of that past work. This research project was designed as the conclusion of a larger effort to help understand, evaluate and validate the impact of Maintenance Resource Management (MRM) training programs, and other MRM interventions on participant attitudes, opinions, behaviors, and ultimately on enhanced safety performance. It includes research and development of evaluation methodology as well as examination of psychological constructs and correlates of maintainer performance. In particular, during 2002, three issues were addressed. First, the evaluation of two (independent & different) MRM programs for changing behaviors was undertaken. In one case we were able to further apply the approach to measuring written communication developed during 2001 (Taylor, 2002; Taylor & Thomas, 2003). Second, the MRM/TOQ surveys were made available for completion on the internet. The responses from these on-line surveys were automatically linked to a results calculator (like the one developed and described in Taylor, 2002) to aid industry users in analyzing and evaluating their local survey data on the internet. Third, the main trends and themes from our research about MRM programs over the past dozen years were reviewed.

    Introduction. Intra-abdominal pressure (IAP) measurement is an indispensable tool for the diagnosis of abdominal hypertension. Different techniques have been described in the literature and applied in the clinical setting. Methods. A porcine model was created to simulate an abdominal compartment syndrome ranging from baseline IAP to 30 mmHg. Three different measurement techniques were applied, comprising telemetric piezoresistive probes at two different sites (epigastric and pelvic) for direct pressure measurement and intragastric and intravesical probes for indirect measurement. Results. The mean difference between the invasive IAP measurements using telemetric pressure probes and the IVP measurements was -0.58 mmHg. The bias between the invasive IAP measurements and the IGP measurements was 3.8 mmHg. Compared to the realistic results of the intraperitoneal and intravesical measurements, the intragastric data showed a strong tendency towards decreased values. The hydrostatic character of the IAP was eliminated at high-pressure levels. Conclusion. We conclude that intragastric pressure measurement is potentially hazardous and might lead to inaccurately low intra-abdominal pressure values. This may result in missed diagnosis of elevated abdominal pressure or even ACS. The intravesical measurements showed the most accurate values during baseline pressure and both high-pressure plateaus.

    Full Text Available It is argued in this article that Micah 7:8-20 forms an apt conclusion to the book of Micah. As was the case with Micah 1, the concluding section also focusses on Yahweh and his dealings with the people of the earth. There is a universal tendency to be detected in this section as well. An important aspect to notice� is� the liturgical nature of chapters six and seven, especially 7:8-20. There is a vagueness, almost a timelessness, imbuing this section. This could be intended allowing later generations of believers to apply these words to� their� own� circumstances. With Micah 7:8-20 as the concluding section of the book, one is left with a sense of well-roundedness, of completeness. The collection of oracles attributed� to Micah in general has a sombre tone. For this very reason Micah� 7:8-20� seems� to� change� the mood. It breathes hope into a negative atmosphere of judgment. It ends with a strong emphasis on the power of Yahweh, the power of forgiveness.

    2010-01-01

    The NASA Glenn Research Center has developed and tested a Total Water Content Isokinetic Sampling Probe. Since, by its nature, it is not sensitive to cloud water particle phase nor size, it is particularly attractive to support super-cooled large droplet and high ice water content aircraft icing studies. The instrument comprises the Sampling Probe, Sample Flow Control, and Water Vapor Measurement subsystems. Results and conclusions are presented from probe tests in the NASA Glenn Icing Research Tunnel (IRT) during January and February 2009. The use of reference probe heat and the control of air pressure in the water vapor measurement subsystem are discussed. Several run-time error sources were found to produce identifiable signatures that are presented and discussed. Some of the differences between measured Isokinetic Total Water Content Probe and IRT calibration seems to be caused by tunnel humidification and moisture/ice crystal blow around. Droplet size, airspeed, and liquid water content effects also appear to be present in the IRT calibration. Based upon test results, the authors provide recommendations for future Isokinetic Total Water Content Probe development.

    The INTRAVAL WIPP-2 test case is based on data from site investigations carried out at the Waste Isolation Pilot Plant (WIPP) in New Mexico, USA. The site has been chosen as a potential location for a radioactive waste repository. Extensive investigations have been carried out, focused mainly on groundwater flow and transport in the Culebra Dolomite, the main pathway for transport of radionuclides off the site by groundwater in the case of an accidental borehole intrusion into the repository. Five teams studied the test case. Two teams addressed issues involved in the treatment of heterogeneity. Stochastic models and a Monte Carlo approach were used. One team quantified the increased uncertainty resulting from fewer data and explored the issues involved in validation of stochastic models. A second team developed a new method for conditioning stochastic models on head data. Two other teams examined issues relating to the choice of conceptual models. Two-dimensional vertical cross-section models were used to explore the importance of vertical flow. The fifth team advocate the use of a variety of models to highlight the most important processes and parameters. Conclusions from each team experiment are analysed. (J.S.). 4 refs., 11 figs

    Full Text Available Impaired decision behavior has been repeatedly observed in schizophrenia patients. We investigated several cognitive mechanisms that might contribute to the jumping-to-conclusions bias (JTC seen in schizophrenia patients: biases in information-gathering, information weighting and integration, and overconfidence, using the process tracing paradigm Mouselab. Mouselab allows for an in-depth exploration of various decision-making processes in a structured information environment. A total of 37 schizophrenia patients and 30 healthy controls participated in the experiment. Although showing less focused and systematic information search, schizophrenia patients practically considered all pieces of information and showed no JTC in the sense of collecting less pieces of evidence. Choices of patients and controls both approximated a rational solution quite well, but patients showed more extreme confidence ratings. Both groups mainly used weighted additive decision strategies for information integration and only a small proportion relied on simple heuristics. Under high stress induced by affective valence plus time pressure, however, schizophrenia patients switched to equal weighting strategies: less valid cues and more valid ones were weighted equally.

    Highlights: • Activation calculation of two WWER-440 type nuclear power plants. • Detailed description of the applied activation calculation methodology. • Graphical results for total activity and waste index categorization. • General conclusions for activation applicable in the case of PWR reactors. - Abstract: Activation calculations for two nuclear power plants of WWER-440 type have been performed by the authors in order to assist the decommissioning planning by assessing the radioactive inventory present at the time of and at different times after the final shutdown. According to related international literature and studies performed earlier by the authors, considering the activity more than 99% of this inventory is concentrated in the materials directly surrounding the reactor core, where the predominant evolution of radionuclides is generated by neutron induced nuclear reactions. In order to obtain the highest possible accuracy in modelling, three-dimensional Monte Carlo neutron transport calculations were performed. Besides the methods and models applied to these analyses, the paper also summarizes the results that can be generally applied to such nuclear power plant types. At the time of shutdown, the total activity of the stainless steel components is about 6 × 10{sup 16} Bq and 1.3 × 10{sup 17} Bq for the two NPPs considered. The biological shielding concrete constitutes approximately 7 × 10{sup 13} Bq and 1.1 × 10{sup 14} Bq.

    In our bloodstream, there are plenty of red blood cells (RBC), which function as an important oxygen carrier in our bodies. Each RBC consists of millions of haemoglobin (Hb), which is made up from globin and iron. If any deficiency/malfunction of any globin, it will lead to anaemia as indicated in low Hb level while iron deficiency anaemia (IDA) is anaemic due to the lacking of iron as indicated in low Hb and ferritin levels. IDA affects almost two billion people globally while anaemia without iron deficiency, such as thalassaemia, affects almost 4.5% in Malaysian population. These anaemic conditions have similar clinical symptoms like fatigue, dizziness, in which disturb their cognitive development and productivity in workplace. In areas without proper medical access, many anaemic individuals were misdiagnosed and treated with iron tablets because they were thought to have iron deficiency anaemia due to low Hb content. But, excess iron is toxic to the body. Misdiagnosis can be avoided by iron status assessment. We hereby review the currently available iron status parameters in laboratory and field study with the conclusion of demonstrating the importance of a need for iron reader, in the effort to reduce the prevalence of IDA globally.

    Total knee arthroplasty (TKA) is generally accepted as the definitive treatment for advanced knee arthritis after patients fail nonoperative treatments; however, the safety and efficacy of TKA compared to continued nonoperative treatment has never been proven in high-quality, randomized controlled trials. Recently, a 2015 Danish study published a 12-month follow-up on a cohort of patients randomized to either a TKA or continued nonsurgical management for advanced knee osteoarthritis (OA). The authors reported significantly greater improvement in the TKA group in functional outcome scores such as the overall Knee Injury and Osteoarthritis Outcome Score (KOOS 4 score), the KOOS subscales, EQ-5D descriptive index, and timed get up-and-go and 20-m walk tests; however, patients in the TKA did suffer significantly more serious adverse events (SAE). The authors concluded that TKA combined with additional nonoperative care postoperatively is more efficacious than nonsurgical treatment alone in terms of improving pain, function, and quality of life at 12 months but is associated with more SAE. The purpose of this review is to identify the strengths and weaknesses of this trial, interpret its outcomes within the context of prior literature, and evaluate the validity of its conclusions.

  4. Blast Testing Issues and TBI; Experimental Models that Lead to Wrong Conclusions

    2015-04-01

    Full Text Available Over the past several years we have noticed an increase in the number of blast injury studies published in peer-reviewed biomedical journals that have utilized improperly conceived experiments. Data from these studies will lead to false conclusions and more confusion than advancement in the understanding of blast injury, particularly blast neurotrauma. Computational methods to properly characterize the blast environment have been available for decades. These methods, combined with a basic understanding of blast wave phenomena enable researchers to extract useful information from well documented experiments. This basic understanding must include the differences and interrelationships of static pressure, dynamic pressure, reflected pressure, and total or stagnation pressure in transient shockwave flows, how they relate to loading of objects, and how they are properly measured. However, it is critical that the research community effectively overcomes the confusion that has been compounded by a misunderstanding of the differences between the loading produced by a free field explosive blast and loading produced by a conventional shock tube. The principles of blast scaling have been well established for decades and when properly applied will do much to repair these problems.This paper provides guidance regarding proper experimental methods and offers insights into the implications of improperly designed and executed tests. Through application of computational methods, useful data can be extracted from well documented historical tests, and future work can be conducted in a way to maximize the effectiveness and use of valuable biological test data.

    1994-01-01

    An 18 month study to evaluate the potential of inertial fusion energy (IFE) for electric power production has been completed. The primary objective of the study was to provide the US Department of Energy with an evaluation of the potential of inertial fusion for electric power production. The study included the conceptual design of two inertial fusion power plants. Osiris uses an induction linac heavy ion beam driver, and SOMBRERO uses a krypton fluoride laser driver. Conceptual designs were completed for the reactors, power conversion and plant facilities, and drivers. Environmental and safety aspects, technical issues, technology development needs, and economics of the final point designs were assessed and compared. This paper summarizes the results and conclusions of the conceptual designs and results of the assessment studies. We conclude that IFE has the potential of producing technically credible designs with environmental, safety, and economics characteristics that are just as attractive as magnetic fusion. Realizing this potential will require additional research and development on target physics, chamber design, target production and injection systems, and drivers. ((orig.))

  6. KiKK: An endless story or the long way to come to a conclusion?

    2009-01-01

    More than one year after the publication of the KiKK-Study (Epidemiological Study on Childhood Cancer in the Vicinity of Nuclear Power Plants), which reported a statistical correlation between the proximity of a person's residence to the nearest nuclear power plant, at the time of diagnosis, and the person's risk of contracting cancer (or leukaemia) prior to his or her fifth birthday, the SSK presented its assessment and the related scientific explanatory statement to the public on the occasion of an expert discussion in Bonn on February 26, 2009, This article describes the background of the SSK deliberations and gives a survey of its essential results and conclusions. In total, the results are unsatisfactory, since the SSK was not able to explain the findings of the KiKK-Study. However, this was not unexpected considering the international state of knowledge regarding the development of childhood cancer. Considering the fact, that the radiation exposure of members of the public, originating from the nuclear power plants even at the locations of the potentially highest exposures, is by orders of magnitude lower than the natural radiation exposures, the SSK was able to exclude the radiation from the nuclear power plants as cause of the observed increased relative risks. Any more far-reaching explanation attempts would be mere speculation. It is still a long way to know how childhood cancer develops and how the results of the KiKK-Study or other small-scale enhancements of the cancer risk can be explained. (orig.)

    The results of the recently published doses obtained by medical staff working in pulsed radiation fields, and performing interventional radiology (IR) or interventional cardiology (IC) procedures, as well as applications of radionuclides in nuclear medicine (NM), have shown significantly high levels of exposure, mainly to the hands and other parts of their bodies uncovered by protective equipment. The coordinated project ORAMED (Optimization of Radiation Protection of Medical Staff) was set-up by participation of 12 European countries and 34 IR/IC and NM departments, with the 5 main tasks: (i) optimization of radiation protection in IR and IC,with the aim to standardize a unified method of extremities and eye lens doses estimation, for 3 cardiac and 5 interventional diagnostic and therapeutic examinations; (ii) verification of the possibilities to use active personal dosemeters for typical pulsed radiation fields used in IR and IC; (iii) contribution to the extremities and eye lens dose reduction in nuclear medicine; (iv) development and application of a suitable eye lens dosemeter; and (v) elaboration of training materials and guidelines for radiation protection issues at IR, IC and NM workplaces. The present study presents some important results and recommendations for dose reduction and avoidance of some typical failures during work near ionizing radiation sources. (P.A.)

    1997-01-01

    During the Medicus field test we gained experience using the teleradiology system for almost daily teleconferences between a radiology department and clinics for internal medicine, urology, and gynecology. The existing system has a high degree of functionality. The full 12-bit data format is available using the DICOM protocol. A data security concept is implemented, ensuring data integrity, privacy and authentication of communication partners. This concept covers the areas of organization, technique, user training, and software implementation. A future system should be a general purpose radiology workstation covering viewing functionality, image manipulation, and digital archive access. Dedicated teleradiology features have to be a part. Specialized evaluation software, e.g. for dynamic MRI, should be integratable in a modular way. For data exchange with other systems and for the synchronization of teleconference sessions, the protocols should be independent of the network standard used (ISDN, Ethernet, ATM) and based on the DICOM protocol. Extensions of the existing standard are therefore necessary. Besides future technical developments, reimbursement for teleradiology must be accomplished. (orig.) [de

  9. Symbolic Spaces in Late Capitalism, Where Art is A Proposal and not a Conclusion

    Full Text Available Capitalism is the predominant conceptual system configuring and forming our reality. It is difficult, perhaps almost impossible, to imagine another one, because we are immersed in the conceptual approaches of this reality, the one of capitalism. Art is able to represent, symbolically and accurately this conceptual reality, but also to encourage us to imagine other realities even if it is only able display this one accurately (without critic. The concept of this reality is based now on consumption through virtual identities. The value of art is affected by this premise, meaning that the artist is valuable mainly because he is converted into a logo, a valuable signature on the work. This phenomenon not only reflects our conceptual approach to reality but also unveils it, revealing new aspects of our reality and what we think about it. However, art is able to go further and present different approaches to our concepts about reality. It could mean that art promotes us to imagine other realities, at least unconsciously, for both art producers and viewers. Finally, this scheme has to be included in a new revolutionary tool, the web, a virtual multidimensional space, where contemporary art takes part. Therefore, in the “space” of the web, art can communicate more than ever and can transform itself and present this transformation beyond the established limits, contributing to produce a more flexible and imaginative way of thinking.

  10. Los Alamos PWR feed-and-bleed studies summary results and conclusions

    The adequacy of shutdown decay heat removal in pressurized water reactors (PWRs) is currently under investigation by the Nuclear Regulatory Commission. One part of this effort is review of feed-and-bleed procedures that could be used if the normal cooling mode through the steam generators was unavailable. Feed-and-bleed cooling is effected by manually activating the high-pressure injection (HPI) system and opening the power-operated relief valves (PORVs) to release the core decay energy. The feasibility of the feed-and-bleed concept as a diverse mode of heat removal has been evaluated at the Los Alamos National Laboratory. The TRAC-PF1 code has been used to predict the expected performances of the Oconee-1 and Calvert Cliffs-1 reactors of Babcock and Wilcox and Combustion Engineering, respectively, and the Zion-1 and H.B. Robinson-2 plants of Westinghouse. Feed and bleed was successfully applied in each of the four plants studied, provided it was initiated no later than the time of loss-of-secondary heat sink

  11. OECD/CSNI specialist meeting on fuel coolant interactions: summary and conclusions

    International Nuclear Information System (INIS)

    1997-01-01

    Research activities and interest on fuel-coolant interaction (FCI) have been increased and broadened since the last CSNI Specialist Meeting held in January 1993. Significant experimental and analytical research has been performed in many OECD countries and others. The growing international interest is, in large part, due to the emphasis on broader aspects of FCI ranging from melt quenching and coolability to energetic explosions (both in- and ex-vessel), and their relevance and applications to next-generation reactor design as well as accident management strategies. The objectives of the meeting are to review the knowledge and to obtain consensus on the phenomenology of FCI and in predicting FCI behavior in LWRs severe accidents; to identify those areas of FCI phenomena and prediction which are important for reactor safety but still poorly understood and require further study with clear methodologies; to inform the community and the regulatory agencies of the status of FCI issues, especially in the application to accident management and future reactor designs. The various sessions are: reactor applications, pre-mixing, propagation / trigger, experiments

  12. [Domestic elder abuse and neglect--conclusions from the evaluation of a model project].

    Science.gov (United States)

    Görgen, T; Nägele, B

    2005-02-01

    The main task of a federally funded model project in the German city of Hannover was to develop approaches for prevention and intervention in the field of domestic elder abuse. Over a three year period (1998-2001), different approaches--like a telephone helpline for senior citizens, and social workers operating as counsellors for elderly people and their relatives--were tested at a local level. The paper presents results from the evaluation of the project and draws conclusions for future prevention and intervention in the field. The authors argue that the explicit use of the conceptual framework of "violence"/"abuse" creates potentials for scandalizing the issue and is therefore supportive for media appearance, whereas it can impede the approach to the main target groups (elderly people and their relatives) and reduce accessibility of counselling services for potential clients. In the light of evaluation results the focus of the project ("domestic elder abuse" or "violence against elderly people in close relationships") was too narrow for a local project. Counselling services were used in a relatively small number of cases; analyses of cases show that incidents of domestic elder abuse are often embedded in complex problem constellations. Cases brought to the attention of the model project were multifaceted and not limited to incidents of neglect and abuse of elderly care recipients caused by caregiver overload. Cases of intimate violence in partnerships and of intergenerational violence without any of the participants being dependent on care show the need to develop a broader concept of domestic elder abuse. Integration of the concepts of domestic violence, violence against women, elder abuse/neglect and abuse/neglect in caregiving relationships is necessary on a conceptual level as well as on the level of interagency cooperation of institutions dealing with cases of "elder abuse".

  13. On the challenges of drawing conclusions from p-values just below 0.05

    Science.gov (United States)

    2015-01-01

    In recent years, researchers have attempted to provide an indication of the prevalence of inflated Type 1 error rates by analyzing the distribution of p-values in the published literature. De Winter & Dodou (2015) analyzed the distribution (and its change over time) of a large number of p-values automatically extracted from abstracts in the scientific literature. They concluded there is a ‘surge of p-values between 0.041–0.049 in recent decades’ which ‘suggests (but does not prove) questionable research practices have increased over the past 25 years.’ I show the changes in the ratio of fractions of p-values between 0.041–0.049 over the years are better explained by assuming the average power has decreased over time. Furthermore, I propose that their observation that p-values just below 0.05 increase more strongly than p-values above 0.05 can be explained by an increase in publication bias (or the file drawer effect) over the years (cf. Fanelli, 2012; Pautasso, 2010, which has led to a relative decrease of ‘marginally significant’ p-values in abstracts in the literature (instead of an increase in p-values just below 0.05). I explain why researchers analyzing large numbers of p-values need to relate their assumptions to a model of p-value distributions that takes into account the average power of the performed studies, the ratio of true positives to false positives in the literature, the effects of publication bias, and the Type 1 error rate (and possible mechanisms through which it has inflated). Finally, I discuss why publication bias and underpowered studies might be a bigger problem for science than inflated Type 1 error rates, and explain the challenges when attempting to draw conclusions about inflated Type 1 error rates from a large heterogeneous set of p-values.

    2017-09-01

    Previous research involving the probabilistic reasoning 'beads task' has consistently demonstrated a jumping-to-conclusions (JTC) bias, where individuals with delusions make decisions based on limited evidence. However, recent studies have suggested that miscomprehension may be confounding the beads task. The current study aimed to test the conventional beads task against a conceptually simpler probabilistic reasoning "box task" METHODS: One hundred non-clinical participants completed both the beads task and the box task, and the Peters et al. Delusions Inventory (PDI) to assess for delusion-proneness. The number of 'draws to decision' was assessed for both tasks. Additionally, the total amount of on-screen evidence was manipulated for the box task, and two new box task measures were assessed (i.e., 'proportion of evidence requested' and 'deviation from optimal solution'). Despite being conceptually similar, the two tasks did not correlate, and participants requested significantly less information on the beads task relative to the box task. High-delusion-prone participants did not demonstrate hastier decisions on either task; in fact, for box task, this group was observed to be significantly more conservative than low-delusion-prone group. Neither task was incentivized; results need replication with a clinical sample. Participants, and particularly those identified as high-delusion-prone, displayed a more conservative style of responding on the novel box task, relative to the beads task. The two tasks, whilst conceptually similar, appear to be tapping different cognitive processes. The implications of these results are discussed in relation to the JTC bias and the theoretical mechanisms thought to underlie it. Copyright © 2016 Elsevier Ltd. All rights reserved.

  15. Managing nuclear waste: a better idea (Excerpt of conclusions and recommendations)

    International Nuclear Information System (INIS)

    1984-12-01

    The panel concludes that an immediate effort must be made to improve the credibility, internal flexibility and cost-effectiveness of the Office of Civilian Radioactive Waste Management (OCRWM). However, in recognition that no modification to DOE/OCRWM organization would necessarily provide adequate stability and continuity, it is our principal recommendation that investigation of the specific steps necessary to implement, for example, a dedicated federally chartered corporation (the first choice of the Panel voting on organizational tests), should be undertaken immediately so that Congress can have a precise understanding of the legislative changes required to bring about such an organization. The main thrust of the Panel study has dealt with the structure and capabilities of various organizational alternatives for managing the high-level radioactive waste management program. The Panel also gave consideration to the financing processes of the Nuclear Waste Policy Act (NWPA), and to certain financing alternatives which might be substituted for the existing mechanisms. In doing so, the Panel encountered an array of financial uncertainties which confront the radioactive waste management program as it moves forward over the next two decades. At this juncture, it is extremely difficult to predict how future events, programmatic developments, and economic influences will affect the financing structure and cost level over the term of the program. It is the Panel's conclusion that the financing mechanism provided by Congress under the Nuclear Waste Policy Act appears to be fair, amenable to administrative implementation and cost controls, and sufficiently flexible to accommodate the full-recovery requirement of the legislation. Under NWPA, utilities are assessed a fee of 1 mill per kilowatthour of nuclear-generated electricity, plus a one-time fee for spent fuel accumulated prior to April 7, 1983

  16. Radioactive-waste ocean dumping will have negligible enviromental impact. Conclusion of draft assessment of NSB

    Energy Technology Data Exchange (ETDEWEB)

    1976-11-01

    This draft report is the result of extensive studies based on the best available information in the field of oceanography, marine radiobiology and health physics. On various basic considerations, assessment was undertaken, and the following conclusion was reached. The quantity of radioactivity to be dumped at one time is assumed to be 500 Ci in the case of test dumping, and 10/sup 5/ Ci/year in the case of full-scale dumping. The conditions required for the dumping sea area are that the bottom water flow and upwelling amount are limited, and that the sea bottom is flat. The horizontal dispersion coefficient of 10/sup 7/ cm/sup 2//sec and the vertical dispersion coefficient of 2 x 10/sup 2/ cm/sup 2//sec are assumed. It is assumed that the radionuclides in the disposed package would leached out as soon as it reaches the sea bottom, and would not show any physicochemical behavior. Typycal radionuclides are classified into 5 groups in terms of their half lives, and their estimated concentrations at 1 km depth are tabulated. The maximum level of individual dose and the magnitude of population dose were assessed on the fishermen working in the dumping sea area, and the adults, children and infants who were expected to receive higher dose on account of the larger intake of fish products than average. The dose level given with the dose assessment model and various panamentors under the dumping conditions is much lower than natural radiation and the permissible level recommended by ICRP.

    The scope of the FUNMIG Integrated Project (IP) was to improve the knowledge base on biogeochemical processes in the geosphere which are relevant for the safety of radioactive waste repositories. An important part of this project involved the interaction between data producers (research) and data users (radioactive waste management organisations in Europe). The aim thereof was to foster the benefits of the research work for performance assessment (PA), and in a broader sense, for the safety case of radioactive waste repositories. For this purpose a specifically adapted procedure was elaborated. Thus, relevant features, events and processes (FEPs) for the three host rock types, clay, crystalline and salt, were taken from internationally accepted catalogues and mapped onto each of the 108 research tasks conducted during the FUNMIG project by a standardised procedure. The main outcome thereof was a host-rock specific tool (Task Evaluation Table) in which the relevance and benefits of the research results were evaluated both from the PA and research perspective. Virtually all generated data within FUNMIG are related to the safety-relevant FEP-groups “transport mechanisms” and “retardation”. Generally speaking, much of the work within FUNMIG helped to support and to increase confidence in the simplified PA transport and retardation models used for calculating radionuclide (RN) transport through the host rock. Some of the studies on retardation processes (e.g. coupled sorption-redox processes at the mineral–water interface) yielded valuable data for all three rock types dealt within the IP. However, most of the studies provided improved insight regarding host-rock specific features and processes, the majority of this work being dedicated to clay-rich and crystalline host rocks. For both of these host rock types, FUNMIG has significantly contributed to improving understanding on a conceptual level, both by providing new experimental data at different spatial

  18. Conclusions of the specialist meeting on operator AIDS for severe accident management and training (SAMOA)

    International Nuclear Information System (INIS)

    1994-01-01

    The scope of the Specialist Meeting was limited to operator aids for accident management which were in operation or could be soon. Moreover, the meeting concentrated on the management of accidents beyond the design basis, including tools which might be extended from the design basis range into the severe accident area. Relevant simulation tools for operator training were also part of the scope of the meeting. The presentations showed that the design and implementation of operator aids were closely related to the organisation adopted by the user, whether it was a utility or a governmental agency. The most common organisation is to share the management of severe accidents among two groups of people: the operating team in the Control Room (CR) and a team of specialists in a Technical Support Centre (TSC). The CR is in charge of the operation of the plant in all conditions using a set of procedures and guidelines, while the experts in the TSC are able to produce in-depth analyses of the plant state and its evolution. The responsibility is shared between the CR and the TSC during accident progression. The TSC acts as a support for the CR for reactor operation and takes charge of the predictions of radioactive releases (source term, accident progression, release and dispersion of radioactive substances, as well as the interaction with public authorities). But this type of organisation is not general and the differences can induce different approaches in the design of operator aids. The first session was dedicated to operator aids for control rooms, the second session to operator aids for technical support centres

  19. Conclusions: The Future of Shark Management and Conservation in the Northeast Pacific Ocean.

    Science.gov (United States)

    Lowry, Dayv

    Human interactions with sharks in the Northeast Pacific Ocean (NEP) have occurred for millennia but were largely limited to nearshore encounters as target and nontarget catch in fisheries. The arrival of Spanish explorers in the mid-1500s, followed by subsequent waves of explorers and colonizers from Europe and Russia, did little to change this relationship, until the mid-1800s. As technological advances conferred the ability to exploit marine fish further offshore and in deeper water, substantial fisheries developed and many of these encountered, and sometimes directly targeted, sharks. As these fisheries rose and fell with market demands and fluctuations in the abundance of target species, the collective consciousness of the nations fishing this region came to realize that adequate management plans with clear policy guidance rooted in conservation were crucial to sustaining both biodiversity and abundance of marine resources. With explicitly defined management regions governed by scientifically informed bodies that consider both societal and ecological needs, systems have been in place to manage and conserve marine species, including sharks, for over four decades now in the NEP. While policy evolution has largely limited directed fishing pressure as a threat for most shark species, bycatch is still a concern. Additionally, habitat degradation and destruction, ocean acidification, and global climate change are anticipated to fundamentally alter the ecosystems sharks are an integral part of in coming decades and centuries. Adequate conservation and management of sharks in the NEP, and around the world, moving into this period of uncertainty will rely upon comprehensive, integrated management of the ecosystem rooted in international coordination and cooperation. Far from being an unattainable goal, steps are being made each day to 'move the needle' in this direction-for the benefit of all. © 2017 Elsevier Ltd All rights reserved.

  20. A decade of human genome project conclusion: Scientific diffusion about our genome knowledge.

    2016-05-06

    The Human Genome Project (HGP) was initiated in 1990 and completed in 2003. It aimed to sequence the whole human genome. Although it represented an advance in understanding the human genome and its complexity, many questions remained unanswered. Other projects were launched in order to unravel the mysteries of our genome, including the ENCyclopedia of DNA Elements (ENCODE). This review aims to analyze the evolution of scientific knowledge related to both the HGP and ENCODE projects. Data were retrieved from scientific articles published in 1990-2014, a period comprising the development and the 10 years following the HGP completion. The fact that only 20,000 genes are protein and RNA-coding is one of the most striking HGP results. A new concept about the organization of genome arose. The ENCODE project was initiated in 2003 and targeted to map the functional elements of the human genome. This project revealed that the human genome is pervasively transcribed. Therefore, it was determined that a large part of the non-protein coding regions are functional. Finally, a more sophisticated view of chromatin structure emerged. The mechanistic functioning of the genome has been redrafted, revealing a much more complex picture. Besides, a gene-centric conception of the organism has to be reviewed. A number of criticisms have emerged against the ENCODE project approaches, raising the question of whether non-conserved but biochemically active regions are truly functional. Thus, HGP and ENCODE projects accomplished a great map of the human genome, but the data generated still requires further in depth analysis. © 2016 by The International Union of Biochemistry and Molecular Biology, 44:215-223, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

  1. Determinants of physician empathy during medical education: hypothetical conclusions from an exploratory qualitative survey of practicing physicians

    Science.gov (United States)

    2014-01-01

    Background Empathy is an outcome-relevant physician characteristic and thus a crucial component of high-quality communication in health care. However, the factors that promote and inhibit the development of empathy during medical education have not been extensively researched. Also, currently there is no explicit research on the perspective of practicing physicians on the subject. Therefore the aim of our study was to explore physicians’ views of the positive and negative influences on the development of empathy during their medical education, as well as in their everyday work as physicians. Method We administered a written Qualitative Short Survey to 63 physicians in seven specialties. They were able to respond anonymously. Our open-ended question was: “What educational content in the course of your studies and/or your specialist training had a positive or negative effect on your empathy?” We analyzed the data using thematic content analysis following Mayring’s approach. Results Forty-two physicians took part in our survey. All together, they mentioned 68 specific factors (37 positive, 29 negative, 2 neutral) from which six themes emerged: 1. In general, medical education does not promote the development of empathy. 2. Recognizing the psycho-social dimensions of care fosters empathy. 3. Interactions with patients in medical practice promote empathy. 4. Physicians’ active self-development through reflective practice helps the development of empathy. 5. Interactions with colleagues can both promote and inhibit empathy through their role modeling of empathic and non-empathic behavior. 6. Stress, time pressure, and adverse working conditions are detrimental to empathy development. Conclusions Our results provide an overview of what might influence the development of clinical empathy, as well as hypothetical conclusions about how to promote it. Reflective practice seems to be lacking in current medical curricula and could be incorporated. Raising physicians

  3. Advanced thermal-hydraulic and neutronic codes: current and future applications. Summary and conclusions

    International Nuclear Information System (INIS)

    2001-05-01

    An OECD Workshop on Advanced Thermal-Hydraulic and Neutronic Codes Applications was held from 10 to 13 April 2000, in Barcelona, Spain, sponsored by the Committee on the Safety of Nuclear Installations (CSNI) of the OECD Nuclear Energy Agency (NEA). It was organised in collaboration with the Spanish Nuclear Safety Council (CSN) and hosted by CSN and the Polytechnic University of Catalonia (UPC) in collaboration with the Spanish Electricity Association (UNESA). The objectives of the Workshop were to review the developments since the previous CSNI Workshop held in Annapolis [NEA/CSNI/ R(97)4; NUREG/CP-0159], to analyse the present status of maturity and remnant needs of thermal-hydraulic (TH) and neutronic system codes and methods, and finally to evaluate the role of these tools in the evolving regulatory environment. The Technical Sessions and Discussion Sessions covered the following topics: - Regulatory requirements for Best-Estimate (BE) code assessment; - Application of TH and neutronic codes for current safety issues; - Uncertainty analysis; - Needs for integral plant transient and accident analysis; - Simulators and fast running codes; - Advances in next generation TH and neutronic codes; - Future trends in physical modeling; - Long term plans for development of advanced codes. The focus of the Workshop was on system codes. An incursion was made, however, in the new field of applying Computational Fluid Dynamic (CFD) codes to nuclear safety analysis. As a general conclusion, the Barcelona Workshop can be considered representative of the progress towards the targets marked at Annapolis almost four years ago. The Annapolis Workshop had identified areas where further development and specific improvements were needed, among them: multi-field models, transport of interfacial area, 2D and 3D thermal-hydraulics, 3-D neutronics consistent with level of details of thermal-hydraulics. Recommendations issued at Annapolis included: developing small pilot/test codes for

  4. LEAping to conclusions: A computational reanalysis of late embryogenesis abundant proteins and their possible roles

    Full Text Available Abstract Background The late embryogenesis abundant (LEA proteins cover a number of loosely related groups of proteins, originally found in plants but now being found in non-plant species. Their precise function is unknown, though considerable evidence suggests that LEA proteins are involved in desiccation resistance. Using a number of statistically-based bioinformatics tools the classification of a large set of LEA proteins, covering all Groups, is reexamined together with some previous findings. Searches based on peptide composition return proteins with similar composition to different LEA Groups; keyword clustering is then applied to reveal keywords and phrases suggestive of the Groups' properties. Results Previous research has suggested that glycine is characteristic of LEA proteins, but it is only highly over-represented in Groups 1 and 2, while alanine, thought characteristic of Group 2, is over-represented in Group 3, 4 and 6 but under-represented in Groups 1 and 2. However, for LEA Groups 1 2 and 3 it is shown that glutamine is very significantly over-represented, while cysteine, phenylalanine, isoleucine, leucine and tryptophan are significantly under-represented. There is also evidence that the Group 4 LEA proteins are more appropriately redistributed to Group 2 and Group 3. Similarly, Group 5 is better found among the Group 3 LEA proteins. Conclusions There is evidence that Group 2 and Group 3 LEA proteins, though distinct, might be related. This relationship is also evident in the overlapping sets of keywords for the two Groups, emphasising alpha-helical structure and, at a larger scale, filaments, all of which fits well with experimental evidence that proteins from both Groups are natively unstructured, but become structured under stress conditions. The keywords support localisation of LEA proteins both in the nucleus and associated with the cytoskeleton, and a mode of action similar to chaperones, perhaps the cold shock chaperones

  5. Summary of the workshop robustness of electrical systems - Conclusions and recommendations

    International Nuclear Information System (INIS)

    2015-01-01

    The workshop included an opening session, seven sessions with participant presentations followed by short discussions, and a facilitated discussion session. The contributions presented were devoted to discussions of national post-Fukushima regulatory programme developments, methods to determine allowable coping time for electric power recovery, electric power system simulation methods development and benchmarking efforts, analysis of component capability, and approaches to facilitate electric power system recovery from extended loss of AC power. The following conclusions and recommendations are made based on workshop presentations, discussions during particular sessions, and facilitated discussions: - Based upon the panel discussions at the end of the workshop, a majority of the participants suggested the need for continuing efforts after the ROBELSYS workshop and particularly the importance of launching a more permanent international working group on modeling tools and methods related to nuclear power plant electrical power system studies. The working group would be modelled on WGRISK. (It is recognized that creating such a permanent working group would require a multi-year commitment of CSNI and the participants). - It will be very beneficial to continue international information sharing of the following items, eventually leading to development of suitable international electrical standards: System and component requirements for addressing beyond design basis external events; Recommended practice for incorporating diversity in the onsite electrical power system; Recommended practice for relaxing electric power protection features used in emergency situations (assuring margin against spurious electrical shutdowns); Recommended practice for qualification requirements for existing systems and portable components used to cope with AC station blackout. - There is a need for further development and improvements in the analysis and simulation of the following

    The workshop ended with a summary session. The Workshop Chair and Technical Reporter summarised the main findings, and provided the opportunity for further discussion and comment. There was a discussion on the way forward, including reporting, future meetings and other means of networking. Participants provided feedback on the workshop to assist with the planning and conduct of future events. The main conclusions arising from the workshop were as follows: - Licensees are generally positive about engaging with regulators to raise awareness about and support improvements in LMfS/SC. - More active and visible senior regulatory leadership increases the effectiveness of LMfS/SC interventions. Examples of practical actions that senior regulatory leaders can take include raising LMfS/SC matters at senior levels within licensee organisations and feeding back results of discussions to regulatory staff so that priorities and expectations are aligned. - A common 'language', and trust between regulators and licensees are fundamental factors for effective oversight of LMfS/SC. - The message from the previous workshop in 2007 on the importance of integrating LMfS/SC into normal regulatory business was reinforced. - A combination of integrated and targeted LMfS/SC interventions is considered to be effective to take account of the advantages and disadvantages of both approaches. - In line with the conclusions from the previous workshop, influence is preferred to 'enforcement'. Where enforcement action is required, this is likely to be associated with tangible manifestations of LMfS/SC safety culture issues, such as license condition violations. - A fundamental principle of regulatory oversight of LMfS/SC is to encourage licensees to understand and take ownership of issues and solutions. Strategies include: Discussion of regulatory perceptions to test for shared regulator/licensee understanding, - Working together with licensees to develop guidance and understanding (e.g., through

    2002-01-01

    The Workshop on Operator Training for Severe Accident Management (SAM) and Instrumentation Capabilities During Severe Accidents was organised in collaboration with Electricite de France (Service Etudes et Projets Thermiques et Nucleaires). There were 34 participants, representing thirteen OECD Member countries, the Russian Federation and the OECD/NEA. Almost half the participants represented utilities. The second largest group was regulatory authorities and their technical support organisations. Basically, the Workshop was a follow-up to the 1997 Second Specialist Meeting on Operator Aids for Severe Accident Management (SAMOA-2) [Reports NEA/CSNI/R(97)10 and 27] and to the 1992 Specialist Meeting on Instrumentation to Manage Severe Accidents [Reports NEA/CSNI/R(92)11 and (93)3]. It was aimed at sharing and comparing progress made and experience gained from these two meetings, emphasizing practical lessons learnt during training or incidents as well as feedback from instrumentation capability assessment. The objectives of the Workshop were therefore: - to exchange information on recent and current activities in the area of operator training for SAM, and lessons learnt during the management of real incidents ('operator' is defined hear as all personnel involved in SAM); - to compare capabilities and use of instrumentation available during severe accidents; - to monitor progress made; - to identify and discuss differences between approaches relevant to reactor safety; - and to make recommendations to the Working Group on the Analysis and Management of Accidents and the CSNI (GAMA). The Workshop was organised into five sessions: - 1: Introduction; - 2: Tools and Methods; - 3: Training Programmes and Experience; - 4: SAM Organisation Efficiency; - 5: Instrumentation Capabilities. It was concluded by a Panel and General Discussion. This report presents the summary and conclusions: the meeting confirmed that only limited information is needed for making required decisions

    direct scientific return, the comet encounter is of engineering value to other missions planning comet encounters. With the successful conclusion of its extended mission, DS1 undertook a hyperextended mission. This phase of its flight was dedicated to final testing of the advanced technologies on board. With the mission at more than three times its planned lifetime, this offered an excellent opportunity to obtain unplanned data on the effects of long-term operation in space. All nine of the hardware technologies were used during the hyperextended mission, with a focus on the ion propulsion system. Following this period of extremely aggressive testing, with no further technology or science objectives, the mission was terminated on December 18, 2001, with the powering off of the spacecraft s transmitter, although the receiver was left on. By the end of its mission, DS1 had returned a wealth of important science data and engineering data for future missions. It did so following the shortest time from pre-phase A through launch of any NASA interplanetary mission in the modern era and the lowest cost of any NASA interplanetary mission ever conducted (measured in same year dollars, including the launch cost). This paper will describe the encounter with comet Borrelly, the hyperextended mission, and summarize the overall results of the Deep Space 1 project.

    Full Text Available In the context of modern industry the molecular vacuum pumps (MVP are widely used. The analyzed current market of vacuum technology enables drawing a conclusion that this equipment holds one of the leading positions among the high-vacuum facilities of pumping due to their advantages such as insensitivity to the atmosphere breakthrough, ability to pump out heavy gases quickly, rapid start-up time, and oil-free pumping.The earlier developed authors’ mathematical model and calculation program are used to assess the influence efficiency of the key geometrical parameters of flowing part of the cylindrical molecular pump on its main characteristics. The obtained dependences allow us to solve a relevant, but not completely resolved as yet problem of optimizing the high-vacuum pumping facilities in case of their operation in a wide range of pressures on the suction side.The paper presents graphs of the pumping speed and ratio of the cylindrical vacuum molecular pump pressures versus various parameters of the flowing part, such as the angle of inclination of the helix, the relative diameter and the number of helical starts. Conclusions are drawn.

    2015-01-01

    'Constructing Memory: An International Conference and Debate on the Preservation of Records, Knowledge and Memory of Radioactive Waste across Generations' was met with a great deal of enthusiasm by participants. The wealth of new topics, the presence of both specialists and of interested stakeholders, and the structure of the conference that allowed both scholarly presentations and group discussions, were particularly appreciated. Academics found that it laid the basis for new academic research. One participant expressed his appreciation in this way: 'It gave me food for thought not only on the issue of nuclear waste information but also on other preservation issues'. Overall, the conference upheld the findings of the RK and M initiative's Phase I and its main work directions. Namely, it confirmed the RK and M overarching findings that: There is no single mechanism or technique that would achieve, alone, the preservation of RK and M over centuries and millennia. An RK and M preservation method is needed whose components offer a variety of RK and M transmission mechanisms that are integrated with one another or that complement one another with a view to maximising information accessibility, understandability and survivability over the timescales considered. The RK and M initiative is thus well advised to continue working on a systemic approach for RK and M preservation and to map its various components and highlight their internal synergies. At a higher level, the RK and M also found confirmation that: There should be no intention to forgo, at any time, records, knowledge and memory (RK and M) of the repository and of the waste it contains. Enabling future members of society to make informed decisions is part of responsible, ethically sound and sustainable radioactive waste management. During the conference's long-term session, its Rapporteur, Fabrice Boissier (Andra), emphasised the idea that the medium term should last as long as

It was possible to separate the sample into three groups : the type "Baianinha Piracicaba" with a medium mean fruit diameter per tree, the "Baía" with large fruits and the new type "Baianinha Araras" with small fruits. 6. The experimental plot was selected as beeing reasonably uniform. The statistical analysis however revealed significant, though not very important heterogeneities which can only be partially responsible for the variations between trees mentioned above (quadro VI. 7. There is a constant negative linear correlation between the number of fruits per tree and the mean fruit diameter, the coefficient r beeing the same in all years and equal to 0.5 (quadro X. On the average, a loss of 1 mm in mean diameter corresponds to a gain of 50 fruits per tree. 8. The error within trees both when comparing the errors per tree in the same year or of different years showed significant variations which are however without much praticai importance. The annual means of these errors (sD vary from 4,69 mm in 1937 to 7,56 mm in 1939 (quadro VIII. 9. The error within trees cannot be used as a reliable measure since the variations within trees are highly abnormal, restricted by two physiological limits which prevent the appearance of very small or very large fruits and show sometimes a tendency to asymetry and bimodality. 10. The possible causes for the abnormal variation "within" were studied in some detail. The only positive result was obtained when comparing the production on older branches with that on recent strong off-shoots. In some case it was possible to collect the fruits on these components of a tree separately, the older branches forming the lower and the other the top parts of the tree (fig. 7. The latter produce always larger fruits (quadro IX and fig. 2. 11. Heterogeneity of the root stocks seems to be the most probable cause of the heterogeneity between trees. It has been shown by other experiments, not yet

    Full Text Available Whereas formerly metallic materials were used extensively and for various purposes in the machines manufacturing industry, nowadays new materials are sought that can replace the "conventional" machines manufacturing materials with new ones. This is especially challenging in areas where parts need to be able to withstand very tough conditions, such as high temperatures or large forces applied to them. The current paper intends to analyze some of the most widely used materials for high-strength applications. A special focus in this regard is on the one hand in fiber-reinforced composite materials with the polymer matrix and on the other hand on basalt. The most important properties, processing technologies and applications of these materials are analyzed and discussed and conclusions are drawn regarding their compatibility with the intended purpose.

    Various aspects of a clinical session on 'High dose-rate afterloading in the treatment of cancer of the uterus' at the International Workshop, London in April 1978 are discussed. The results of high dose-rate afterloading treatment were at least as good as those of conventional low dose-rate therapy. However, there is still a need to optimize dose fractionation and technique according to the type and stage of the disease to achieve the best results with the least distress for the patient. It would appear that, at the doses used, side effects with high dose-rate afterloading were few and probably related to the external rather than to the intracavitary therapy. High dose-rate afterloading therapy has obvious social and economic advantages and is thus of interest to all countries. (U.K.)

    1994-01-01

    The present issue of 'Les Cahiers de COGEMAGAZINE', dedicated to role played by Cogema in the nuclear fuel cycling, ends with a short account on perspectives and concluding considerations. In the world nuclear fuel industry the most active zones appear to be France, Japan, China, Taiwan and Korea. A real expansion is to be expected in UO 2 market for PWRs. Also rapid development will be recorded by the production of MOF (mixed oxide fuels) especially due to the inception of British reprocessing plant at Thorp and the increase of number of MOF-fuelled reactors. The most significant lines of progress related to the new fuels are estimated to be: high burn-up (by increasing the resistance to fission gas pressure and irradiation), improvement of response to power excursions, fuel matrices of stronger retention, increase in the plutonium content of MOF, 100% MOF-fuelled reactors, optimizing the utilization of consumable poisons (for PWR) and very high burn-up and very long service lifetimes (for Breeders). In a nuclear environment, now in a rather low expansion rate, the French nuclear fuel industry enjoys the benefit of: an important national market, industrial experimented teams able to tackle all the steps from design to realization of a diversity of nuclear fuel types, fabrication facilities combining suppleness to clients' demands with requirements for high quality, a highly-rated worldwide position, and important capabilities of technological further development. An annex is added showing the percentage involvement of COGEMA and FRAMATOME in the fields of UO 2 -PuO 2 fuel production for PWR, fuels for Breeder, WER and experimental reactors and transport. Also participation of other European companies like PECHINEY, BELGONUCLEAIRE and SIEMENS is indicated

    This Air Concerted Action successfully developed a standard methodology to help integrate non-food crop production in rural areas with niche energy markets. The project developed and used a common methodology for comparing the costs of different energy crop production and conversion options across the six participating nations. The partners tested the methodology and ran examples in each of the two heat and one liquid biofuel niche markets. The examples demonstrated that at the current crop yields and with the current conversion technology, the delivered heat and liquid fuel from biomass were not competitive with that from fossil fuels, even in the three niche markets. It was confirmed, however, that biomass was important non only as a potential ''clean'' alternative fuel, but as an alternative crop for farmers which could additionally boost employment in rural communities. Following the inclusion of grants, subsidies and co-firing options, the partners tested the extended methodology and then ran another series of examples in the selected niche markets. (Author)

    Full Text Available This article aims to present major guidelines in case-law of the Court of Justice of the European Union (EU in the field of public procurement and concessions. Court, with the mission to enforce EU law in the interpretation and uniform application of the Treaties, has contributed to establishing the content of the principles which apply in the award, conclusion, amendment and termination of public procurement contracts and concessions, and in shaping the principles applicable to review against abuses carried out by the contracting entity in the award procedure. This article analyzed the principles of transparency and impartiality in the award of these contracts and described the means by which these goals are achieved in practice: non-discriminatory description of the subject-matter of the contract, equal treatment of operators involved in awarding the contract, mutualrecognition of diplomas, certificates and other evidence, the principle of equal treatment of public and private operators, appropriate time-limits in which the undertakings concerned of any Member State are able to prepare their offers. Ensuring the application of EU rules in the field of public contractscan not be achieved without the existence of an effective judicial review based on the principle of effectiveness means legal action and the principle of equivalence. Knowledge the content of theseprinciples is particularly important for a uniform application of EU law on public contracts in all Member States.

    Full Text Available Background. Perseveration has been observed in a number of behavioural contexts, including speaking, writing, and drawing. However, no previous report describes patients who show perseveration only for drawing a human figure. Objective. The present report describes a group of patients who show body awareness-related cognitive impairment during a human figure drawing task, a different presentation from previously described neuropsychological cases. Methods. Participants were 15 patients who had a frontal lobe brain tumour around the insula cortex of the right hemisphere and had subsequently undergone a neurosurgical resective operation. Participants were asked to draw a human figure in both “hands-down” and “hands-up” configurations. Results. Eight of the 15 patients drew a human figure with six fingers during the “hands-up” and the “hands-down” human figure drawing tasks (one patient drew eight fingers.

    Background. Perseveration has been observed in a number of behavioural contexts, including speaking, writing, and drawing. However, no previous report describes patients who show perseveration only for drawing a human figure. Objective. The present report describes a group of patients who show body awareness-related cognitive impairment during a human figure drawing task, a different presentation from previously described neuropsychological cases. Methods. Participants were 15 patients who had a frontal lobe brain tumour around the insula cortex of the right hemisphere and had subsequently undergone a neurosurgical resective operation. Participants were asked to draw a human figure in both “hands-down” and “hands-up” configurations. Results. Eight of the 15 patients drew a human figure with six fingers during the “hands-up” and the “hands-down” human figure drawing tasks (one patient drew eight fingers). A statistical analysis of potential lesion areas revealed damage to the right anterior frontal insula and operculum in this group of patients relative to the five-finger drawing group. Conclusions. Our findings reveal a newly described neuropsychological phenomenon that could reflect impairment in attention directed towards body representations. PMID:24876665

    The aims of the study were to identify indicators of quality of nursing care from the perceptions of patients and nurses, and to determine the congruence between patients' and nurses' perceptions. The paper is presented in two parts. Part 1 included the background and methods to the study and the findings from the comparison of patients' and nurses' perceptions. Part 2 describes the perceptions of patients and nurses, and draws conclusions drawn from the study as a whole. Patients and nurses in hospital wards were interviewed using the critical incident technique. We grouped 4546 indicators of high and low quality nursing care generated from the interview transcripts into 316 subcategories, 68 categories and 31 themes. The themes were grouped into eight clusters: therapeutic context for care, attitudes and sensitivity, teaching and leadership, motivation to nurse, monitoring and informing, high-dependency care, efficiency and thoroughness, reflection and anticipation. As shown in Part 1 of the paper, congruence between patients' and nurses' perceptions of quality was high and significant, although there was some difference of emphasis. The findings support an emerging theory of interpersonal competence and quality in nursing care.

Realizaram-se estudos de casos com nove sujeitos, sendo os dados coletados por meio de entrevistas narrativas e análise documental e submetidos a um processo de análise textual discursiva. O referencial que embasou a pesquisa foi o da Psicologia Histórico-Cultural de Vygotski. Os achados apontam fatores que dificultaram a conclusão do ensino superior – como o processo de seleção, que ignora as necessidades dos cegos; a falta de preparo das instituições para atender os deficientes; os preconceitos de docentes. Ao mesmo tempo, indicam fatores que favoreceram essa conclusão – como o auxílio aos cegos por parte de docentes e familiares, a tomada de consciência sobre a importância da formação universitária para suas vidas futuras gerando vontade para alcançá-la.

  1. Part-time work and adolescent heavy episodic drinking: the influence of family and community context.

    Previous studies on part-time work and alcohol use suggest that teenagers who work longer hours drink more heavily. The purpose of this study was to investigate whether family- and community-level factors moderate the relationship between part-time work hours and heavy episodic drinking. Data were drawn from the Canadian Community Health Survey, a cross-sectional study of a nationally representative sample of Canadians. The survey included 8,080 respondents 15-19 years of age who reported work hours and frequency of heavy episodic drinking over the past 12 months. These respondents were located in 136 counties or municipalities across Canada. On average, work hours were positively associated with the frequency of heavy drinking by teenagers in the past 12 months. At the community level, the proportion of teenagers in each community drinking any alcohol was independently and positively associated with respondents' frequency of heavy drinking. In terms of moderating effects, we found that the work hours-drinking association was weaker among youth from low socioeconomic status families. Examination of community-level factors indicated that longer work hours were more strongly associated with heavy episodic drinking in communities with high rates of teen alcohol abstinence. Although the cross-sectional data prohibit any firm conclusions on how family and community factors influence the work-alcohol use relationship, these data suggest that interventions to reduce heavy episodic drinking among teens should address the broader environmental as well as the individual determinants.

    This study uses two studies about the role of managed-care programs in serving Medicaid long-term care clients in Florida to illustrate how different research designs can reach divergent conclusions. Two reports from different groups using essentially the same database to assess the impact of managed care on a group of older Medicaid clients served by a Nursing Home Diversion Program reached different conclusions. The report from Florida's Office of Program Policy Analysis and Government Accountability concluded that the Diversion program saved money, whereas the report from the Florida Policy Exchange Center on Aging at the University of South Florida reached basically the opposite conclusion. Both agreed that the capitation rate was too high. How the policy questions are framed and analyzed can affect the conclusions reached. A variety of factors can influence the apparent effects of programmatic interventions. Evaluations must take relevant confounding variables into account.

  3. Misrepresentation of neuroscience data might give rise to misleading conclusions in the media: the case of attention deficit hyperactivity disorder.

    Francois Gonon

    Full Text Available BACKGROUND: There is often a huge gap between neurobiological facts and firm conclusions stated by the media. Data misrepresentation in the conclusions and summaries of neuroscience articles might contribute to this gap. METHODOLOGY/PRINCIPAL FINDINGS: Using the case of attention deficit hyperactivity disorder (ADHD, we identified three types of misrepresentation. The first relies on prominent inconsistencies between results and claimed conclusions and was observed in two scientific reports dealing with ADHD. Only one out of the 61 media articles echoing both scientific reports adequately described the results and, thus questioned the claimed conclusion. The second type of misrepresentation consists in putting a firm conclusion in the summary while raw data that strongly limit the claim are only given in the results section. To quantify this misrepresentation we analyzed the summaries of all articles asserting that polymorphisms of the gene coding for the D4 dopaminergic receptor are associated with ADHD. Only 25 summaries out of 159 also mentioned that this association confers a small risk. This misrepresentation is also observed in most media articles reporting on ADHD and the D4 gene. The third misrepresentation consists in extrapolating basic and pre-clinical findings to new therapeutic prospects in inappropriate ways. Indeed, analysis of all ADHD-related studies in mice showed that 23% of the conclusions were overstated. The frequency of this overstatement was positively related with the impact factor of the journal. CONCLUSION/SIGNIFICANCE: Data misrepresentations are frequent in the scientific literature dealing with ADHD and may contribute to the appearance of misleading conclusions in the media. In synergy with citation distortions and publication biases they influence social representations and bias the scientific evidence in favor of the view that ADHD is primarily caused by biological factors. We discuss the social consequences and

    The study covered in this paper is designed to review the current situation in terms of functional analysis, in order to find a functional analysis method for mechanical parts able to serve as a substrate for expressing operating safety constraints, time-related performance or any other tag of function description. This paper comprises three parts: The first is devoted to general notions of the formats used by the various functional analyses. It attempts to explain the three types of format: behavioural, structural and functional. It tackles the notions of trees and bottom-up and top-down approaches. It proposes examining the link between the expected functions of the systems and the hardware supporting these functions. It attempts to make a distinction between ``operators`` and ``operands`` enabling the notion of object to be linked to that of the three types of format seen above. It ends with a reminder of the distinction between semi-formal and formal. The second part analyses the current situation of functional analysis of the mechanical and control-instrumentation parts of power production plants, through a bibliographical search. The results of this second part are however disappointing. The purpose of the third part of the study is a prototype format built up from the considerations of the first two parts. This format meets our requirements better than those of the bibliographical analysis, but it could doubtless be improved: application of this format to RCV highlights its advantages, but also underlines the improvements needed. Given the deadlines of the Mexsyco project, the decision was taken to suspend development of this format for the time being and use a method currently being produced and based on use of the current functional breakdown (basic plant systems) and of a modular tree-structure representation of the control-instrumentation of a basic plant system.

    2010-10-01

    Full Text Available A comprehensive data driven modeling experiment is presented in a two-part paper. In this first part, an extensive data-driven modeling experiment is proposed. The most important concerns regarding the way data driven modeling (DDM techniques and data were handled, compared, and evaluated, and the basis on which findings and conclusions were drawn are discussed. A concise review of key articles that presented comparisons among various DDM techniques is presented. Six DDM techniques, namely, neural networks, genetic programming, evolutionary polynomial regression, support vector machines, M5 model trees, and K-nearest neighbors are proposed and explained. Multiple linear regression and naïve models are also suggested as baseline for comparison with the various techniques. Five datasets from Canada and Europe representing evapotranspiration, upper and lower layer soil moisture content, and rainfall-runoff process are described and proposed, in the second paper, for the modeling experiment. Twelve different realizations (groups from each dataset are created by a procedure involving random sampling. Each group contains three subsets; training, cross-validation, and testing. Each modeling technique is proposed to be applied to each of the 12 groups of each dataset. This way, both prediction accuracy and uncertainty of the modeling techniques can be evaluated. The description of the datasets, the implementation of the modeling techniques, results and analysis, and the findings of the modeling experiment are deferred to the second part of this paper.

  7. Evaluation of an IPCC climate report. An analysis of conclusions on the possible regional consequences of climate change

    2010-01-01

    This report contains the results of a study of the reliability of the regional chapters (H9-16) of the contribution of Working Group II to the Fourth Climate Report of the IPCC (the sub report on consequences, adaptation and vulnerability). Moreover an assessment was made of the possible consequences of errors for the conclusions in the high level summaries of that report. The Netherlands Environmental Assessment Agency did not detect any errors that may undermine the main conclusions of the scientific UN Climate Panel IPCC of 2007 on the possible future consequences of climate change. However, some of the substantiations of the conclusions lack clarity. To prevent lack of clarity and inaccuracies the IPCC needs to invest more in quality checks. [nl

  8. Alternative global goodness metrics and sensitivity analysis: heuristics to check the robustness of conclusions from studies comparing virtual screening methods.

    2008-02-01

    We introduce two ways of testing the robustness of conclusions from studies comparing virtual screening methods: alternative "global goodness" metrics and sensitivity analysis. While the robustness tests cannot eliminate all biases in virtual screening comparisons, they are useful as a "reality check" for any given study. To illustrate this, we apply them to a set of enrichments published in McGaughey et al. (J. Chem. Inf. Model. 2007, 47, 1504-1519) where 11 target protein/ligand combinations are tested on 2D and 3D similarity methods, plus docking. The major conclusions in that paper, for instance, that ligand-based methods are better than docking methods, hold up. However, some minor conclusions, such as Glide being the best docking method, do not.

    The Viking molecular analysis experiment has demonstrated the absence (within the detection limits which range from levels of parts per million to below parts per billion) of organic substances in the Martian surface soil at the two Viking landing sites. Laboratory experiments with sterile and nonsterile antarctic samples further demonstrate the capability and reliability of the instrument. The circimstances under which organic components could have escaped detection, such as inaccessibility or extreme thermal stability of organic polymers, are discussed but are found to be unlikely. The inability of the instrument to detect free oxygen evolved from soil samples is pointed out

    Symptom severity and neuropsychological deficits negatively influence functional outcomes in patients with schizophrenia. Recent research implicates specific types of biased thinking styles (e.g. jumping-to-conclusions) in the pathogenesis of schizophrenia. This is the first study to test the impact of jumping-to-conclusions on functional outcome in schizophrenia. The aim of the study was to investigate the association of psychopathology, neuropsychology and JTC with subjective quality of life, vocational outcome and housing status in schizophrenia. Analyses were carried out both cross-sectionally at baseline, and longitudinally over the course of symptomatic improvement in the immediate aftermath of a psychotic exacerbation. Seventy-nine patients with schizophrenia were included in the study. Data concerning the variables of interest were collected at baseline, after one month, and after six months. Positive symptomatology was the most significant predictor of subjective and vocational outcome and changes across time. Verbal memory deficits were associated with functional status cross-sectionally, whereas general cognitive capacity significantly predicted functional changes over time. Improvement of the jumping-to-conclusions bias positively affected vocational outcome. Though limited, the observed effect of this bias on real-world functioning highlights the possible usefulness of interventions aimed at improving (meta)cognitive deficits in schizophrenia.

  17. Decision-making when data and inferences are not conclusive: risk-benefit and acceptable regret approach.

    2008-07-01

    The absolute truth in research is unobtainable, as no evidence or research hypothesis is ever 100% conclusive. Therefore, all data and inferences can in principle be considered as "inconclusive." Scientific inference and decision-making need to take into account errors, which are unavoidable in the research enterprise. The errors can occur at the level of conclusions that aim to discern the truthfulness of research hypothesis based on the accuracy of research evidence and hypothesis, and decisions, the goal of which is to enable optimal decision-making under present and specific circumstances. To optimize the chance of both correct conclusions and correct decisions, the synthesis of all major statistical approaches to clinical research is needed. The integration of these approaches (frequentist, Bayesian, and decision-analytic) can be accomplished through formal risk:benefit (R:B) analysis. This chapter illustrates the rational choice of a research hypothesis using R:B analysis based on decision-theoretic expected utility theory framework and the concept of "acceptable regret" to calculate the threshold probability of the "truth" above which the benefit of accepting a research hypothesis outweighs its risks.

    Dissociative electron attachment to F2 has been observed in the energy range 0-140 meV, at a resolution of 6 meV (full width at half maximum). Results show conclusively a sharp, resolution-limited threshold behavior consistent with an s-wave cross section varying as sq rt of epsilon. Two accurate theoretical calculations predict only p-wave behavior varying as the sq rt of epsilon. Several nonadiabatic coupling effects leading to s-wave behavior are outlined.

    2004-01-01

    Full Text Available Abstract In 2000, the National Research Council (NRC, an arm of the National Academy of Sciences, released a report entitled, "Toxicological Effects of Methylmercury." The overall conclusion of that report was that, at levels of exposure in some fish- and marine mammal-consuming communities (including those in the Faroe Islands and New Zealand, subtle but significant adverse effects on neuropsychological development were occurring as a result of in utero exposure. Since the release of that report, there has been continuing discussion of the public health relevance of current levels of exposure to Methylmercury. Much of this discussion has been linked to the release of the most recent longitudinal update of the Seychelles Island study. It has recently been posited that these findings supercede those of the NRC committee, and that based on the Seychelles findings, there is little or no risk of adverse neurodevelopmental effects at current levels of exposure. In this commentary, members of the NRC committee address the conclusions from the NRC report in light of the recent Seychelles data. We conclude that no evidence has emerged since the publication of the NRC report that alters the findings of that report.

    2004-01-01

    TRUSTNET is a European pluralistic think tank network on the governance of hazardous activities since 1997. It is involving the participation of some 150 key decision makers, stakeholders and experts at European, national and local levels in activities having impact on health and the environment. The participants of TRUSTNET are representatives of public authorities at national and European levels, industry, trade unions, local governments, NGOs. They are also consumers or lay citizens, together with a multidisciplinary group of experts in risk management, public health, political sciences, sociology, psychology, economics, law and ethics. TRUSTNET is supported by the European Commission (DG- Research - Radiation protection) as a Concerted Action. The work programme of TRUSTNET is based on a participatory methodology and a co-expertise of actual case studies involving experts and non-experts. From 1997 to 1999, TRUSTNET has identified the severe difficulties and multiple social blockages affecting the credibility, effectiveness and legitimacy of traditional regulatory framework of hazardous activities. It has also identified emerging features of inclusive risk governance as a major opportunity for overcoming the observed difficulties. The conclusions of the 1997-1999 exercise have been reported in 2000 in the 'TRUSTNET Framework: a New Perspective on Risk Governance'. From 2001 to 2003, TRUSTNET has carried on the reflection and more specifically investigated the possible strategies for implementing in Europe inclusive governance in the various activities entailing risks for health and the environment. The presentation ('Towards Inclusive Governance') will outline presenting the main conclusions of this 2001-2003 exercise. (author)

  5. Jumping to Conclusions Is Associated with Paranoia but Not General Suspiciousness: A Comparison of Two Versions of the Probabilistic Reasoning Paradigm

    Directory of Open Access Journals (Sweden)

    Steffen Moritz

    2012-01-01

    Full Text Available Theoretical models ascribe jumping to conclusions (JTCs a prominent role in the pathogenesis of paranoia. While many earlier studies corroborated this account, some newer investigations have found no or only small associations of the JTC bias with paranoid symptoms. The present study examined whether these inconsistencies in part reflect methodological differences across studies. The study was built upon the psychometric high-risk paradigm. A total of 1899 subjects from the general population took part in an online survey and were administered the Paranoia Checklist as well as one of two different variants of the probabilistic reasoning task: one variant with a traditional instruction (a and one novel variant that combines probability estimates with decision judgments (b. Factor analysis of the Paranoia Checklist yielded an unspecific suspiciousness factor and a psychotic paranoia factor. The latter was significantly associated with scores indicating hasty decision making. Subjects scoring two standard deviations above the mean of the Paranoia Checklist showed an abnormal data-gathering style relative to subjects with normal scores. Findings suggest that the so-called decision threshold parameter is more sensitive than the conventional JTC index. For future research the specific contents of paranoid beliefs deserve more consideration in the investigation of decision making in schizophrenia as JTC seems to be associated with core psychosis-prone features of paranoia only.

  6. Case management directors: how to manage in a transition-focused world: part 2.

    2015-01-01

    Case management directors are in a dynamic position to affect the transition of care of patients across the continuum, work with all levels of providers, and support the financial well-being of a hospital. Most importantly, they can drive good patient outcomes. Although the position is critical on many different levels, there is little to help guide a new director in attending to all the "moving parts" of such a complex role.This is Part 2 of a two-part article written for case management directors, particularly new ones.Part 1 covered the first 4 of 7 tracks: (1) Staffing and Human Resources, (2) Compliance and Accreditation, (3) Discharge Planning and (4) Utilization Review and Revenue Cycle. Part 2 addresses (5) Internal Departmental Relationships (Organizational), (6) External Relationships (Community Agency), and (7) Quality and Program Outcomes.This article attempts to answer the following questions: : The information is most meaningful to those case management directors who work in either stand-alone hospitals or integrated health systems and have frontline case managers (CMs) reporting to them. Part 1 found that case management directors would benefit from further research and documentation of "best practices" related to their role, particularly in the areas of leadership and management. The same conclusion applies to Part 2, which addresses the director's responsibilities outside her immediate department. Leadership and management skills apply as well to building strong, productive relationships across a broad spectrum of external organizations that include payer, provider, and regulatory agencies. At the same time, they must also develop the skills to positively influence the revenue cycle and financial health of both the organization for which they work and those to whom they transition patients. A director of case management with responsibility for transitions of care has more power and influence over patient safety than is commonly known. Few of the

    Full Text Available Agitation is a heterogeneous concept without a uniformly accepted definition, however, it is generally considered as a state of cognitive and motor hyperactivity characterized by excessive or inappropriate motor or verbal activity with marked emotional arousal. Not only the definition but also other aspects of agitated patients’ care are still unsolved and need consensus and improvement. To help the discussion about agitation among experts and improve the identification, management, and treatment of agitation, the 1st International Experts’ Meeting on Agitation was held in October 2016 in Madrid. It was attended by 20 experts from Europe and Latin America with broad experience in the clinical management of agitated patients. The present document summarizes the key conclusions of this meeting and highlights the need for an updated protocol of agitation management and treatment, the promotion of education and training among healthcare professionals to improve the care of these patients and the necessity to generate clinical data of agitated episodes.

    2015-03-01

    Full Text Available Patients with delusions exhibit an increased tendency to arrive at decisions based on very limited evidence (jumping-to-conclusions; JTC, making this reasoning bias relevant for the treatment of delusions. Neurocognitive deficits contribute to JTC, but it is not known whether this has any bearing on the clinical syndrome of delusions. We addressed this question by reanalyzing data from an efficacy study of non-pharmacological interventions as adjunctive treatments in schizophrenia. We investigated the longitudinal associations of cognitive functioning, JTC and delusions in patients with psychotic disorders receiving either a metacognitive intervention addressing reasoning biases (n = 59, or cognitive remediation (n = 58. Both interventions improved JTC; in the cognitive remediation group, tentative evidence suggested that better neurocognitive performance contributed to this improvement. However, JTC gains were associated with delusion improvement only in the metacognitive intervention group, suggesting a content-specific mechanism of action.

    Full Text Available Introduction Multiple trauma is one of the leading causes of mortality and morbidity in the population of people under 45 years of age. The consequences of multiple trauma have huge epidemiological, social and economic significance. Objective The aim of the paper was to analyze the conclusive treatment outcome of multiply traumatized patients with respect to their sex, age, injury mechanism and type. METHOD This retrospective study included 100 patients with multiple injuries (ISS>16 treated in the Emergency Room of the Clinical Centre of Serbia in the course of 2004. Clinical, X-ray, laboratory and numerical presentation methods - scores (ISS and GCS were used to show the injury severity. Results Most of the injured were males (80%, and the average age was 40±20 (5-83. Out of the total number of patients who died, 23 (82% were males, and 5 (18% were females. The average age of the patients with fatal outcomes was 48±21 (8-86. Traffic accidents were the leading cause of injury (59%. The median GCS was 10±3 (3-15. The average ISS was 30 (20-66 in the surviving patients, and 53 (27-77 in those who died. Conclusion With respect to sex, in most cases multiple trauma affects males (p<0.01, with the average age of about 40. With respect to injury mechanism, the main cause of the occurrence of multiple trauma is traffic accidents (p<0.01. There is a statistically significant difference in the values of GCS and ISS relative to the definitive outcome (p<0.01. Statistical data processing indicated that there was a statistically significant correlation between mortality and type of injury in a given organic system (p<0.01, but that there was no statistically significant correlation between mortality and age. .

    Cultivated chrysanthemum is an outcrossing hexaploid (2n = 6× = 54) with a disputed mode of inheritance. In this paper, we present a single nucleotide polymorphism (SNP) selection pipeline that was used to design an Affymetrix Axiom array with 183 k SNPs from RNA sequencing data (1). With this array, we genotyped four bi-parental populations (with sizes of 405, 53, 76 and 37 offspring plants respectively), and a cultivar panel of 63 genotypes. Further, we present a method for dosage scoring in hexaploids from signal intensities of the array based on mixture models (2) and validation of selection steps in the SNP selection pipeline (3). The resulting genotypic data is used to draw conclusions on the mode of inheritance in chrysanthemum (4), and to make an inference on allelic expression bias (5). With use of the mixture model approach, we successfully called the dosage of 73,936 out of 183,130 SNPs (40.4%) that segregated in any of the bi-parental populations. To investigate the mode of inheritance, we analysed markers that segregated in the large bi-parental population (n = 405). Analysis of segregation of duplex x nulliplex SNPs resulted in evidence for genome-wide hexasomic inheritance. This evidence was substantiated by the absence of strong linkage between markers in repulsion, which indicated absence of full disomic inheritance. We present the success rate of SNP discovery out of RNA sequencing data as affected by different selection steps, among which SNP coverage over genotypes and use of different types of sequence read mapping software. Genomic dosage highly correlated with relative allele coverage from the RNA sequencing data, indicating that most alleles are expressed according to their genomic dosage. The large population, genotyped with a very large number of markers, is a unique framework for extensive genetic analyses in hexaploid chrysanthemum. As starting point, we show conclusive evidence for genome-wide hexasomic inheritance.

  15. Treatments of Missing Values in Large National Data Affect Conclusions: The Impact of Multiple Imputation on Arthroplasty Research.

    Despite the advantages of large, national datasets, one continuing concern is missing data values. Complete case analysis, where only cases with complete data are analyzed, is commonly used rather than more statistically rigorous approaches such as multiple imputation. This study characterizes the potential selection bias introduced using complete case analysis and compares the results of common regressions using both techniques following unicompartmental knee arthroplasty. Patients undergoing unicompartmental knee arthroplasty were extracted from the 2005 to 2015 National Surgical Quality Improvement Program. As examples, the demographics of patients with and without missing preoperative albumin and hematocrit values were compared. Missing data were then treated with both complete case analysis and multiple imputation (an approach that reproduces the variation and associations that would have been present in a full dataset) and the conclusions of common regressions for adverse outcomes were compared. A total of 6117 patients were included, of which 56.7% were missing at least one value. Younger, female, and healthier patients were more likely to have missing preoperative albumin and hematocrit values. The use of complete case analysis removed 3467 patients from the study in comparison with multiple imputation which included all 6117 patients. The 2 methods of handling missing values led to differing associations of low preoperative laboratory values with commonly studied adverse outcomes. The use of complete case analysis can introduce selection bias and may lead to different conclusions in comparison with the statistically rigorous multiple imputation approach. Joint surgeons should consider the methods of handling missing values when interpreting arthroplasty research. Copyright © 2017 Elsevier Inc. All rights reserved.

    Prenatal and postnatal exposure to tobacco smoke adversely affects maternal and child health. Secondhand smoke (SHS) has been linked causally with sudden infant death syndrome (SIDS) in major health reports. In 1992, the US Environmental Protection Agency (EPA) first noted an association between SHS and SIDS, and both prenatal exposure and postnatal SHS exposure were listed as independent risk factors for SIDS in a 1997 California EPA report (republished in 1999 by the National Cancer Institute) and a 2004 US Surgeon General report. The tobacco industry has used scientific consultants to attack the evidence that SHS causes disease, most often lung cancer. Little is known about the industry's strategies to contest the evidence on maternal and child health. In 2001, a review was published on SIDS that acknowledged funding from the Philip Morris (PM) tobacco company. Tobacco industry documents related to this review were examined to identify the company's influence on the content and conclusions of this review. Tobacco industry documents include 40 million pages of internal memos and reports made available to the public as a result of litigation settlements against the tobacco industry in the United States. Between November 2003 and January 2004, we searched tobacco industry document Internet sites from the University of California Legacy Tobacco Documents Library and the Tobacco Documents Online website. Key terms included "SIDS" and names of key persons. Two authors conducted independent searches with similar key terms, reviewed the documents, and agreed on relevancy through consensus. Thirty documents were identified as relevant. Two drafts (an early version and a final version) of an industry-funded review article on SIDS were identified, and 2 authors independently compared these drafts with the final publication. Formal comments by PM executives made in response to the first draft were also reviewed. We used Science Citation Index in July 2004 to determine

    We examined the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting multiple-domain mild cognitive impairment (md-MCI) in a Chinese sub-sample drawn from elderly population-based study. This study included Chinese participants from the Epidemiology of Dementia in Singapore (EDIS) study aged ≥ 60 years who underwent cognitive screening with the Abbreviated Mental Test and Progressive Forgetfulness Questionnaire. Screen-positive participants subsequently underwent MoCA, MMSE, and a comprehensive formal neuropsychological battery. MCI was defined by Petersen's criteria and further classified into single-domain MCI (sd-MCI) and md-MCI. Area under the receiver operating characteristic curve (AUC) with 95% confidence intervals (CIs) was computed for the MoCA and the MMSE in detecting md-MCI. A total of 300 participants were recruited: 128 (42.7%) were diagnosed with no cognitive impairment (NCI), 47 (15.7%) with sd-MCI, and 83 (28.0%) with md-MCI. Forty-one participants were excluded, 7 (2.3%) had dementia, and 34 (11.3%) had only objective cognitive impairment without subjective complaints. Although the MoCA had a significantly larger AUC than the MMSE (0.94 (95% CI = 0.91-0.97) vs. 0.91 (95% CI = 0.86-0.95), p= 0.04), at optimal cut-off points, the MoCA (19/20) was equivalent to the MMSE (25/26) in detecting md-MCI (sensitivity: 0.80 vs. 0.87, specificity: 0.92 vs. 0.80). Both screening tests had good discriminant validity and can be used in detecting md-MCI in a sub-sample of Chinese drawn from a population-based study.

    After the symposium "Beyond Cholesterol: Prevention and Treatment of Coronary Heart Disease with n-3 Fatty Acids," faculty who presented at the conference submitted manuscripts relating to their conference topics, and these are presented in this supplement. The content of these manuscripts was reviewed, and 2 conference calls were convened. The objective was to summarize existing evidence, gaps in evidence, and future research needed to strengthen recommendations for specific intakes of n-3 fatty acids for different conditions relating to cardiovascular disease. The following 2 questions were the main items discussed. What are the roles of n-3 fatty acids in primary versus secondary prevention of coronary heart disease? What are the roles of n-3 fatty acids in hypertriglyceridemia, in the metabolic syndrome and type 2 diabetes, and in sudden cardiac death, cardiac arrhythmias, and vulnerable plaque? Each area was summarized by using 2 general categories: 1) current knowledge for which general consensus exists, and 2) recommendations for research and policy. Additional references for these conclusions can be found in the articles included in the supplement.

    1980-11-01

    Face haulage equipment used in conjunction with continuous miners (shuttle cars, diesel haulers, battery scoops, and bridge conveyors) was investigated by recording section delay reports for computer analysis to determine the effect of haulage equipment failures and downtime on productivity, pinpoint the causes of machine failures and downtime, and develop the possible design and operational changes required to reduce machine failures and downtime and increase section productivity. For the mobile vehicle type of haulage (shuttle car, diesel hauler, and battery scoop) failure of one unit in multiple unit haulage operations would not normally stop section production. Bridge conveyors as a haulage system provide continuous haulage of section production but when any part of the bridge system fails, the section production is stopped. In the course of this program, it was determined through the use of daily section shift reports on 200 machines that face haulage equipment is responsible for about 40 to 56 minutes of lost section production time per shift. The most prevalent failure for shuttle cars was found to be the trailing cable umbilical. Bridge conveyors had the most trouble with the conveyor subsystem. Discussions of these and other recorded failures are developed with possible solutions outlined for future implementation. This report only covers the face haulage element of the continuous miner system. Companion reports were developed for the continuous miner and roof bolter elements under separate task orders.

  5. [The doctor-patient relationship against the backdrop of patient-centered medicine. The conclusions of dialogical ethics].

    Science.gov (United States)

    Kreß, H

    2012-09-01

    "Health" and "illness" are multilayered terms. The understanding of human health depends, apart from scientific aspects, on people's individual perceptions as well as on aspects of culture and world view. The ideal of patient-centered medicine requires that a physician does not merely have to establish an objectifiable diagnosis. Rather, a physician should also respect the patients' right to self-determination, their personal values, and their subjective view of health and illness. The philosophy of dialogue, which developed in the twentieth century, offers a conceptual background for this ideal. On an empirical basis, the successful communication between doctor and patient can be interpreted as a useful placebo phenomenon. Alternative medicine puts great emphasis on the doctor's attentive care. This also explains why the alternative branch of medicine has appealed to many patients. Therefore, science-oriented medicine should review methods in which the doctor's empathy and dialogue ability are crucial to treatment success. It is part of the physician's responsibility to appreciate the personal perspectives of patients, to respect them and, if necessary, to engage with them critically.

    Meta-analyses of observational studies represent an important tool for assessing efficacy and safety in the pharmacoepidemiologic field. The data from the individual studies are either primary (i.e., collected through interviews or self-administered questionnaires) or secondary (i.e., collected from databases that were established for other purposes). So far, the origin of the data (primary vs. secondary) has not been systematically assessed as a source of heterogeneity in pharmacoepidemiologic meta-analyses. The aim was to assess the impact of considering the source of exposure data as a criterion in sensitivity and subgroup analysis on the conclusions of drug safety meta-analyses. We selected meta-analyses published between 2013 and 2015 in which the intake of frequently used over-the-counter medicines was either the main exposure or a concomitant treatment and the outcome had short latency and induction periods. We stratified the results by origin of data (primary vs. secondary) and compared the new results to those presented originally in the meta-analyses. We used four meta-analyses that fulfilled our criteria of inclusion. The results were selective serotonin reuptake inhibitors and upper gastrointestinal bleeding: original estimate odds ratio (OR) = 1.71 [95% confidence interval (CI) 1.44-2.04], OR primary data = 1.19 (95% CI 0.90-1.58), OR secondary data = 1.81 (95% CI 1.50-2.17); proton pump inhibitors and cardiac events: original estimate hazard ratio (HR) = 1.35 (95% CI 1.18-1.54), HR primary data = 1.05 (95% CI 0.87-1.26), HR secondary data = 1.43 (95% CI 1.23-1.66); non-aspirin non-steroidal anti-inflammatory drugs and myocardial infarction: original estimate risk ratio (RR) = 1.08 (95% CI 0.95-1.22), RR primary data = 0.57 (95% CI 0.34-0.96), RR secondary data = 1.15 (95% CI 1.03-1.28); paracetamol during pregnancy and childhood asthma: original estimate OR = 1.32 (95% CI 1.14-1.52), OR primary data = 1.23 (95% CI 1.06-1.42), OR

    A cross-sectional group study of the effects of aging on brain metabolism as measured with (18)F-FDG-PET was performed using several different partial volume correction (PVC) methods: no correction (NoPVC), Meltzer (MZ), Müller-Gärtner (MG), and the symmetric geometric transfer matrix (SGTM) using 99 subjects aged 65-87years from the Harvard Aging Brain study. Sensitivity to parameter selection was tested for MZ and MG. The various methods and parameter settings resulted in an extremely wide range of conclusions as to the effects of age on metabolism, from almost no changes to virtually all of cortical regions showing a decrease with age. Simulations showed that NoPVC had significant bias that made the age effect on metabolism appear to be much larger and more significant than it is. MZ was found to be the same as NoPVC for liberal brain masks; for conservative brain masks, MZ showed few areas correlated with age. MG and SGTM were found to be similar; however, MG was sensitive to a thresholding parameter that can result in data loss. CSF uptake was surprisingly high at about 15% of that in gray matter. The exclusion of CSF from SGTM and MG models, which is almost universally done, caused a substantial loss in the power to detect age-related changes. This diversity of results reflects the literature on the metabolism of aging and suggests that extreme care should be taken when applying PVC or interpreting results that have been corrected for partial volume effects. Using the SGTM, significant age-related changes of about 7% per decade were found in frontal and cingulate cortices as well as primary visual and insular cortices. Copyright © 2016 Elsevier Inc.

    A cross-sectional group study of the effects of aging on brain metabolism as measured with 18F-FDG PET was performed using several different partial volume correction (PVC) methods: no correction (NoPVC), Meltzer (MZ), Müller-Gärtner (MG), and the symmetric geometric transfer matrix (SGTM) using 99 subjects aged 65-87 from the Harvard Aging Brain study. Sensitivity to parameter selection was tested for MZ and MG. The various methods and parameter settings resulted in an extremely wide range of conclusions as to the effects of age on metabolism, from almost no changes to virtually all of cortical regions showing a decrease with age. Simulations showed that NoPVC had significant bias that made the age effect on metabolism appear to be much larger and more significant than it is. MZ was found to be the same as NoPVC for liberal brain masks; for conservative brain masks, MZ showed few areas correlated with age. MG and SGTM were found to be similar; however, MG was sensitive to a thresholding parameter that can result in data loss. CSF uptake was surprisingly high at about 15% of that in gray matter. Exclusion of CSF from SGTM and MG models, which is almost universally done, caused a substantial loss in the power to detect age-related changes. This diversity of results reflects the literature on the metabolism of aging and suggests that extreme care should be taken when applying PVC or interpreting results that have been corrected for partial volume effects. Using the SGTM, significant age-related changes of about 7% per decade were found in frontal and cingulate cortices as well as primary visual and insular cortices. PMID:26915497

    One of the main goals of the Spanish and Portuguese-Speaking Group of the International Society for Forensic Genetics (GHEP-ISFG) is to promote and contribute to the development and dissemination of scientific knowledge in the field of forensic genetics. Due to this fact, GHEP-ISFG holds different working commissions that are set up to develop activities in scientific aspects of general interest. One of them, the Mixture Commission of GHEP-ISFG, has organized annually, since 2009, a collaborative exercise on analysis and interpretation of autosomal short tandem repeat (STR) mixture profiles. Until now, six exercises have been organized. At the present edition (GHEP-MIX06), with 25 participant laboratories, the exercise main aim was to assess mixture profiles results by issuing a report, from the proposal of a complex mock case. One of the conclusions obtained from this exercise is the increasing tendency of participating laboratories to validate DNA mixture profiles analysis following international recommendations. However, the results have shown some differences among them regarding the edition and also the interpretation of mixture profiles. Besides, although the last revision of ISO/IEC 17025:2017 gives indications of how results should be reported, not all laboratories strictly follow their recommendations. Regarding the statistical aspect, all those laboratories that have performed statistical evaluation of the data have employed the likelihood ratio (LR) as a parameter to evaluate the statistical compatibility. However, LR values obtained show a wide range of variation. This fact could not be attributed to the software employed, since the vast majority of laboratories that performed LR calculation employed the same software (LRmixStudio). Thus, the final allelic composition of the edited mixture profile and the parameters employed in the software could explain this data dispersion. This highlights the need, for each laboratory, to define through internal

    In 2013, illegal drug use was responsible for 1.8% of years of life lost in the European Union, alcohol was responsible for 8.2% and tobacco for 18.2%, imposing economic burdens in excess of 2.5% of GDP. No single European country has optimal governance structures for reducing the harm done by nicotine, illegal drugs and alcohol, and existing ones are poorly designed, fragmented, and sometimes cause harm. Reporting the main science and policy conclusions of a transdisciplinary five-year analysis of the place of addictions in Europe, researchers from 67 scientific institutions addressed these problems by reframing an understanding of addictions.  A new paradigm needs to account for evolutionary evidence which suggests that humans are biologically predisposed to seek out drugs, and that, today, individuals face availability of high drug doses, consequently increasing the risk of harm.  New definitions need to acknowledge that the defining element of addictive drugs is 'heavy use over time', a concept that could replace the diagnostic artefact captured by the clinical term 'substance use disorder', thus opening the door for new substances to be considered such as sugar. Tools of quantitative risk assessment that recognize drugs as toxins could be further deployed to assess regulatory approaches to reducing harm. Re-designed governance of drugs requires embedding policy within a comprehensive societal well-being frame that encompasses a range of domains of well-being, including quality of life, material living conditions and sustainability over time; such a frame adds arguments to the inappropriateness of policies that criminalize individuals for using drugs and that continue to categorize certain drugs as illegal. A health footprint, modelled on the carbon footprint, and using quantitative measures such as years of life lost due to death or disability, could serve as the accountability tool that apportions responsibility for who and what causes drug-related harm.

    In 1987, microbiology became a part of the Swedish scientific program for the safe disposal of high level nuclear waste (HLW). The goal of the microbiology sub-program is to understand how subterranean microorganisms will interact with the performance of a future HLW repository. The Swedish research program on subterranean microbiology has mainly been performed at two sites in granitic rock aquifers at depths ranging from 70 m down to 1240 m; the Stripa research mine in the middle of Sweden and the Aespoe hard rock laboratory (HRL) situated on the south eastern coast of Sweden. Some work has also been performed in co-operation with other national or international research groups in Sweden, Canada and at the natural analogue sites in Oklo in Gabon and Maqarin in Jordan. The most recent report in the SKB technical report series on microbiology and performance assessment, SKB-TR--95-10, gave the state of the art regarding microorganisms and their importance for performance assessment. That report is recommended as a source of knowledge about basic microbiology, microbial ecology of subterranean environments and the nuclear waste disposal concept in a microbiological perspective. The present report summarises results and conclusions achieved during the period 1995 to 1997 and is a continuation of SKB TR 95-10. The report is structured as summary which explains and analyses the obtained results and conclusions in a performance assessment perspective. The scientific basis for the summary is an enclosed series of eleven papers of which eight have gone through an international peer review process for publication in international scientific journals and reports and papers published earlier

  13. Variation in patterns of metal accumulation in thallus parts of Lessonia trabeculata (Laminariales; Phaeophyceae: implications for biomonitoring.

    Directory of Open Access Journals (Sweden)

    Claudio A Sáez

    Full Text Available Seaweeds are well known to concentrate metals from seawater and have been employed as monitors of metal pollution in coastal waters and estuaries. However, research showing that various intrinsic and extrinsic factors can influence metal accumulation, raises doubts about the basis for using seaweeds in biomonitoring programmes. The thallus of brown seaweeds of the order Laminariales (kelps is morphologically complex but there is limited information about the variation in metal accumulation between the different parts, which might result in erroneous conclusions being drawn if not accounted for in the biomonitoring protocol. To assess patterns of individual metals in the differentiated parts of the thallus (blade, stipe, holdfast, concentrations of a wide range of essential and non-essential metals (Fe, Cr, Cu, Zn, Mn, Pb, Cd, Ni and Al were measured in the kelp Lessonia trabeculata. Seaweeds were collected from three sampling stations located at 5, 30 and 60 m from an illegal sewage outfall close to Ventanas, Chile and from a pristine location at Faro Curaumilla. For the majority of metals the highest concentrations in bottom sediment and seaweed samples were found at the site closest to the outfall, with concentrations decreasing with distance from the outfall and at control stations; the exception was Cd, concentrations of which were higher at control stations. The patterns of metal concentrations in different thallus parts were metal specific and independent of sampling station. These results and the available literature suggest that biomonitoring of metals using seaweeds must take account of differences in the accumulation of metals in thallus parts of complex seaweeds.

    The aim of this study was to determine influenza vaccine coverage among children aged 0-18 years in inner city practices in Poland in the 2009/2010 season and factors that might have influenced low vaccination coverage. A retrospective review of 11,735 vaccination charts of children aged 0-18 from seven randomly selected general practices in the capital city of Warsaw and one large practice in the city of Wroclaw was performed. We calculated the numbers of children who were vaccinated in the 2009/2010 season and analyzed the age distribution of vaccinated children. We also reviewed the vaccination history in patients who were vaccinated against influenza including: previous influenza vaccinations, modification (widening) of standard immunization scheme, and a proportion of children who completed the recommended two-dose schedule of vaccination. In the calculations, 95% confidence intervals were used. Out of the total of 11,735 children surveyed, 362 (3.1%, CI: 2.8-3.4%) were vaccinated against influenza in the 2009/2010 season. For 115 of these 362 (31.8%, CI: 27.0-36.6%) children it was their first vaccination against influenza. The mean age of a vaccinated child was 6.0 ± 4.3 years. Children aged 2-5 were most commonly vaccinated (153/362, 42.3%, CI: 37.2-47.4%), while infants (aged 6-12 months) were vaccinated rarely (15/362, 4.4%, CI: 2.2-6.2%). In the group of children younger than 8 years (86/362 children) who were vaccinated for the first time in their life only 29/86 (33.7%, CI: 23.7-43.7%) completed the recommended two-dose schedule. In conclusion, the importance of vaccinating children against influenza is hugely understated in Poland. General physicians should actively recommend annual influenza immunization of children. Recommendations of National Immunization Program concerning influenza vaccine should be clearer, simpler, and easier to implement.

    The Republic of Yemen is located in an arid to semi-arid region. Rainfall rates range from none at certain parts of the country to about 400 mm/yr in its mountainous parts. Rainfall has been harvested and collected in cisterns existed in the mountainous region for generations. In the dry season (October-February) and after the stored water is consumed, people mainly women and children have to travel long distances down wadis to fetch water from the nearest water source which is often not suitable for human consumption. This is the case in the western mountainous region, namely Hajja Governorate, which heavily depends on rain water for drinking, animal watering, domestic uses and irrigation. However, during the dry season this region experiences foggy conditions. This has prompted conducting a fog collection field study in this region to investigate the potential of providing an alternative source for water supply during the dry season. The study consisted of installing 26 standard fog collectors (SFC) of one m2 of polypropylene mesh at 19 sites in Hajja and measuring the daily fog water amounts collected during the period from 1 January to 31 March, 2003. The results indicated that fog collectors located closest to the red sea with an elevation ranged between 2000-2200 meters above sea level and winds from the west direction have produced the highest water output, reaching a maximum of about 4.5 liters per square meter of mesh per day over the three winter months period. The conclusion drawn is that though this technique is cheap, simple and promising, more investigations are still needed on the various parameters contributing to fog collection, such as, relative humidity, temperature and SFCs technologies.

    researching computer-based systems important to safety to get together and to discuss their insights learned from their actual activities. The Workshop was successful in this point. It was attended by 65 people from 15 countries and by 2 international organizations. In general terms, the Workshop attempted to give answers to questions in the following areas: - What are the benefits of using computer-based I and C systems? - What national and international standards and guidance could be universally acceptable from the safety perspective? - What are the regulatory requirements for the current and future generations of digital I and C systems? - What are the major technical issues and challenges associated with applications of digital technology in I and C systems? As a general conclusion, the Workshop can be considered representative of the progress made towards reaching the targets set at the Munich workshop almost five years ago. The Munich workshop had identified areas where further development and specific improvements were needed. The Hluboka workshop has reviewed the development achieved since then. Based on the papers presented at this workshop and on the discussions by the workshop participants, it is evident that the details of the life-cycle activities and the associated acceptance criteria are still in flux and have yet to be universally acceptable. The basic trends from Munich still hold and are reaffirmed in the frame of evolving regulatory and commercial environments. Future international co-operation should strive to reach universally acceptable positions in the above areas

    The NEA workshop in January 2017 gathered representatives of governments, specialists of most aspects of the operation, management and oversight of the full nuclear fuel cycle, and other actors and experts from across the world. Stakeholder involvement in almost all types of nuclear decision making was addressed, and findings were underlined in other technology sectors. The plenary talks and topical presentations provided an overview of major considerations, while dialogue sessions enabled workshop attendees to deepen their understanding and exchange experience. Even considering the specificity of each context, some take-away were clearly supported by presentations, dialogues and exchanges. They constitute a part of the collective wisdom developed when participants from across member countries and sectors come together at such a unique, cross-cutting workshop. It was beneficial to sit together, talk and compare experience with persons from different backgrounds and areas of competence. Stakeholder involvement is not only about what decision is made. It is also about achieving decisions that visibly and transparently reflect stakeholder concerns and input. Stakeholder involvement is 'a process or a tool to reach a decision that is better-informed, sound and widely accepted'. Stakeholder involvement is viewed also as a principle of democracy. There is no one-approach-fits-all: the stakeholder involvement process needs to be adapted to the country-specific context. Across nations, there are different political systems and legal frameworks that are reflected in the mind-sets of populations and approaches to stakeholder involvement. The shape of involvement will be different in the case of a general, policy-type decision or a project or site-specific decision. The involvement process may respond strictly to legal requirements or it may go beyond this minimum. Societal expectations are that stakeholder involvement will go beyond the sharing of information or consultation

    2011-01-01

    Over 200 participants from 33 countries and three international organizations came and actively participated and contributed to focused discussions and the success of the conference. The following points summarize the key conclusions and recommendations of the conference with respect to nuclear safety. 1. The nuclear safety approach is based on the philosophy developed in the 60's: defense in depth principles and deterministic criteria. When properly applied and completed by probabilistic analyses and operational experience feedback, it continues to be a successful approach. However, guarding against the risk of accidents requires constant vigilance and high technical competence and a never ending fight against complacency. In this context, having a strong leadership with a commitment to continuous improvement and a vision of sustained excellence is a key element of nuclear safety. Continuous improvement in safety also should be pursued through scientific research and operational experience feedback. 2. An accident anywhere is of concern to all Member States. Therefore, it is in the interest of all Member States to share and collaborate on safety matters. Participation of all Member States in international nuclear safety instruments and conventions, including liability for nuclear damage, is considered beneficial to global safety. The Convention on Nuclear Safety, the Joint Convention, international cooperation through IAEA and other organizations, bilateral or multilateral arrangements are important elements for establishing networks for sharing and transferring knowledge. It is acknowledged that the IAEA's Safety Fundamentals and Safety Requirements provide a sound foundation for high level nuclear safety. IAEA Safety Standards should be the basis for the establishment and maintenance of safety infrastructure. The IAEA's peer reviews and services such as IRRS, OSART, Site Evaluation and Reactor Safety Reviews provide also a valuable platform for sharing

    in the use of codes. In Russia, for example, every code that has been evaluated has a 'passport' issued were the limits of its applicability are specified. In general, an important part of the review is having an 'integrity' and 'consistency' in the final approval of analysis. The of scaling and extrapolation (applicability) to 'real plants' always needs to be carefully considered. This complex issue is usually 'solved' (although sometimes without a rigorous verification) through discussions with the industry. Regarding applicability of the Western codes, in general, the codes were found to be rather flexible except for Severe Accident applications. Presentations on prescriptive and non-prescriptive regulations indicate that, practically, there is not much difference for a reviewer, because typically the same things need to be done regardless of the approach. A good example may be Canada where, although a relatively non-prescriptive regulatory approach is used, some rather detailed guidelines on how to perform safety analysis reviews are currently being produced. An extreme case may be the Czech approach, who are in a process of developing a fairly rigorous 'algorithm' of plant safety review based on the NRC Standard Review Plan

    The Controlled Parts Management (CPM) system is based on industry standard practices for managing inventory. CPM is designed to record the movement of any type of inventory in a defined region referred to as an Account or SubAccount. The system is used to track the receiving, processing, storing and transfer of inventory parts. CPM provides information on parts, quantity and the exact location of the inventory. CPM is a barcode-based-part tracking system currently used to track controlled parts that are used in the R and D and testing of weapons; this tracking helps maintain the part pedigree that is required for certification of a weapon or weapon test. CPM includes bar code data collection software programmed into portable bar code readers for automating physical inventory services and remote transaction capture. CPM interfaces to other Engineering systems and supports a 'material content' of a weapons test through the test Bill of Materials and assignment of a unique inventory part in CPM. Additional functionality includes the ability to group or join parts, logically or physically and temporary or permanent, to represent discrete parts, containers, subassemblies and assemblies, and groupings.

    Recurrent non-specific low back pain (NSLBP) is increasingly becoming common among adolescents worldwide. A recent study in Zimbabwe showed a relatively high prevalence (28.8 %) among high school students. Influential associated factors, however, remain unclear. This is a significant shortcoming. The aim was to determine personal or lifestyle-related factors associated with recurrent NSLBP among high school adolescents in Harare, Zimbabwe. This study was part of a large epidemiological study conducted in two continuous parts. Part one sought to determine self-reported associated factors among 532 participants (mean age =16 ± 1.72 years) drawn randomly from selected government schools using a reliable and content-validated questionnaire (Kappa coefficient, k = 0.32-1). Part two purposively identified adolescents ( N  = 64, median age =17 years, interquartile range, IQR = 15-18 years) with a history of 'severe' recurrent NSLBP from part one based on a specific eligibility criteria and compared body mass index, relative school bag weight and hamstring flexibility with matched adolescents without NSLBP. Data was analysed using Statistica version 11. Independent t -tests or χ 2 tests of association were used for continuous and categorical data, respectively. The statistical significance was set at p  hamstrings [χ 2 (1) =7.6, p  = 0.006]. Although conclusions from this study are hesitant because of the cross-sectional nature of the study and the relatively small sample size in follow-up study, recurrent NSLBP is associated with perceptions of a heavy school bag, duration of school bag carriage, no sports participation, prolonged sitting on entertainment activities, and tight hamstrings. These findings add to the importance of promoting physical activity at school or home especially aimed at improving muscle flexibility.

  12. Impact of partly ice-free Lake Ladoga on temperature and cloudiness in an anticyclonic winter situation – a case study using a limited area model

    Full Text Available At the end of January 2012, a low-level cloud from partly ice-free Lake Ladoga caused very variable 2-m temperatures in Eastern Finland. The sensitivity of the High Resolution Limited Area Model (HIRLAM to the lake surface conditions was tested in this winter anticyclonic situation. The lake appeared to be (incorrectly totally covered by ice when the lake surface was described with its climatology. Both parametrisation of the lake surface state by using a lake model integrated to the NWP system and objective analysis based on satellite observations independently resulted in a correct description of the partly ice-free Lake Ladoga. In these cases, HIRLAM model forecasts were able to predict cloud formation and its movement as well as 2-m temperature variations in a realistic way. Three main conclusions were drawn. First, HIRLAM could predict the effect of Lake Ladoga on local weather, when the lake surface state was known. Second, the current parametrisation methods of air–surface interactions led to a reliable result in conditions where the different physical processes (local surface processes, radiation and turbulence were not strong, but their combined effect was important. Third, these results encourage work for a better description of the lake surface state in NWP models by fully utilising satellite observations, combined with advanced lake parametrisation and data assimilation methods.

  13. Conclusions about homogeneity and devitrification

    A lot of experimental data concerning homogeneity and devitrification of R7T7 glass have been published. It appears that: - the crystallization process is very limited, - the interfaces due to bubbles and the container wall favor crystallization locally but the ratio of crystallized volume remains always below a few per cents, and - crystallization has no damaging long-term effects as far as leaching tests can be trusted.

    The topic ''mechanics and alteration kinetics of glasses'' is a crucial point for the understanding of the long-term behaviour of nuclear glasses. Kinetic models used in simulation are based on the works made by Grambow who imputes the control of the alteration kinetics of borosilicate glasses to the desorption of the ortho-silica acid produced at the reactive interface. The ensuing kinetics law requires the existence of an equilibrium of the silica at the interface glass/gel and the existence of a linear concentration gradient dissolved in the interstitial gel solution. The role of the gel needs further studies to be well understood. The difficulty lies in the fact that the composition and the structure of the gel varies with time, space (anisotropy) and with the conditions of alteration (temperature, pH, flowrate...). (A.C.)

    The title "Challenges for the Future" implies the challenge to summarize a very complex meeting. Of necessity, I will present a personal impression. My interest is in risk assessment, which I define as a process for summarizing science in support of decision making. Risk assessment is sometimes regarded as arcane numerology, a rigid process of computing risk numbers in which much available science is unused. I am a strong advocate for the broader definition of risk assessment. It is encouraging to learn how much science is becoming available for use in risk assessment for gasoline, its components, and alternative fuels.

    2007-12-01

    Biostatistics is the application of statistics to biologic data. The field of statistics can be broken down into 2 fundamental parts: descriptive and inferential. Descriptive statistics are commonly used to categorize, display, and summarize data. Inferential statistics can be used to make predictions based on a sample obtained from a population or some large body of information. It is these inferences that are used to test specific research hypotheses. This 2-part review will outline important features of descriptive and inferential statistics as they apply to commonly conducted research studies in the biomedical literature. Part 1 in this issue will discuss fundamental topics of statistics and data analysis. Additionally, some of the most commonly used statistical tests found in the biomedical literature will be reviewed in Part 2 in the February 2008 issue.

  5. A spare-parts inventory program for TRIGA reactors

    As is fairly common with new reactor facilities, we had a few spare parts on hand as part of our original purchase when the OSU TRIGA first went critical in March of 1967. Within a year or so, however, it became apparent that we should critically examine our spare parts inventory in order to avoid unnecessary or prolonged outages due to lack of a crucial piece of equipment. Many critical components (those which must be present and operable according to our license or technical specifications) were considered, and a priority list of acquiring these was established. This first list was drawn up in March, 1969, two years after initial criticality, and some key components were ordered. The availability of funds was the overriding restriction then and now. This spare-parts list is reviewed and new components purchased annually; the average amount spent has been about $2,000 per year. This inventory has proved invaluable more than once; without it, we would have had lengthy shutdowns awaiting the arrival of the needed component. The sobering thought, however, is that our spare-parts inventory is still not complete-far from it, in fact, because this would be prohibitively expensive. It is very difficult to guess with 100% accuracy just which component might need replacing, and your $10,000 inventory of spare parts is useless in that instance if it doesn't include the needed part. An idea worth considering is to either (a) encourage General Atomic, through the collective voice of all TRIGA owners, to maintain a rather complete inventory of replacement parts, or (b) maintain an owner's spare-parts pool, financed by contributions from all the facilities. If either of these pools was established, the needed part could reach any facility within the U.S. within a few days, minimizing reactor outage time. (author)

  7. Phase Formation and Transformations in Transmutation Fuel Materials for the LIFE Engine Part I - Path Forward

    2008-01-01

    The current specifications of the LLNL fusion-fission hybrid proposal, namely LIFE, impose severe constraints on materials, and in particular on the nuclear fissile or fertile nuclear fuel and its immediate environment. This constitutes the focus of the present report with special emphasis on phase formation and phase transformations of the transmutation fuel and their consequences on particle and pebble thermal, chemical and mechanical integrities. We first review the work that has been done in recent years to improve materials properties under the Gen-IV project, and with in particular applications to HTGR and MSR, and also under GNEP and AFCI in the USA. Our goal is to assess the nuclear fuel options that currently exist together with their issues. Among the options, it is worth mentioning TRISO, IMF, and molten salts. The later option will not be discussed in details since an entire report is dedicated to it. Then, in a second part, with the specific LIFE specifications in mind, the various fuel options with their most critical issues are revisited with a path forward for each of them in terms of research, both experimental and theoretical. Since LIFE is applicable to very high burn-up of various fuels, distinctions will be made depending on the mission, i.e., energy production or incineration. Finally a few conclusions are drawn in terms of the specific needs for integrated materials modeling and the in depth knowledge on time-evolution thermochemistry that controls and drastically affects the performance of the nuclear materials and their immediate environment. Although LIFE demands materials that very likely have not yet been fully optimized, the challenge are not insurmountable and a well concerted experimental-modeling effort should lead to dramatic advances that should well serve other fission programs such as Gen-IV, GNEP, AFCI as well as the international fusion program, ITER

    experimental data. The estimated time before a rollover differs from the experimental value by 2,7%. The relative error of other modelled characteristics of LNG does not exceed 2,5%.Conclusions are drawn on the possibility to use the technique based on the thermodynamics equations of irreversible processes in a binary methane-ethane mixture to forecast working parameters of LNG storages operation as a part of the ground complexes equipment. The techniques to except the rollover mode can be based on keeping a stable LNG composition in the storage and arranging the fuel mixing when performing operations of storage refill and its draining from rocket fuel tanks at start cancellation.

    Full Text Available Introduction: Temporomandibular disorder (TMD is a universal term referred to herein to collectively denote a series of functional disorders of orofacial structures, the temporomandibular joint (TMJ and the masticatory muscles in particular. Objectives: The aim of our study was to determine the prevalence of temporomandibular disorders within the observed sample population of the northern part of Kosovo and Metohija, as well as the frequency of signs and symptoms of this type of disorder. Methods: The study involved a sample of 300 subjects, aged 18-30 years. The sample comprised the target student population attending the University of Pristina, Kosovska Mitrovica. A random sample, intended for sampling without replacement, was drawn from the target population. All subjects underwent the Helkimo clinical dysfunction index analysis. Results of the analysis were quantified and expressed numerically, based on severity, as the Helkimo anamnestic dysfunction index (Ai and the clinical dysfunction index (Di with specific values assigned thereto accordingly. Results: The prevalence of temporomandibular disorders within the observed sample population totaled 50.7% (Di> 0. In the majority of patients a mild form of TMP (67% was reported. Temporomandibular disorders were more common in women than in men, who appear to be three times as likely to develop the respective condition, demonstrating the ratio of 3:1. The most common TMD signs and symptoms implied mandibular kinetics disturbances (46% and TMJ sounds (45%. The prevalence of pain during mandibular movements amounted to 9%, the palpable TMJ sensitivity to 20% and the palpable sensitivity of masticatory muscles 18%. Headache and otalgia were represented with 13%, that is, 3% in the observed sample. Conclusion: Temporomandibular disorder analysis demonstrates high incidence in the population of the northern part of Kosovo and Metohija. These findings indicate the need for an extensive prevention
