    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.

    2001-01-01

    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)

    A spectroscopic analysis was carried out to clarify the properties of KIC 11145123 - the first main-sequence star with a directly measured core-to-surface rotation profile - based on spectra observed with the High Dispersion Spectrograph (HDS) of the Subaru telescope. The atmospheric parameters (Teff = 7600 K, log g = 4.2, ξ = 3.1 km s-1 and [Fe/H] = -0.71 dex), the radial and rotation velocities, and elemental abundances were obtained by analysing line strengths and fitting line profiles, which were calculated with a 1D LTE model atmosphere. The main properties of KIC 11145123 are: (1) a low [Fe/H] = -0.71 ± 0.11 dex and a high radial velocity of -135.4 ± 0.2 km s-1. These are remarkable among late-A stars. Our best asteroseismic models with this low [Fe/H] have slightly high helium abundance and low masses of 1.4 M⊙. All of these results strongly suggest that KIC 11145123 is a Population II blue straggler; (2) the projected rotation velocity confirms the asteroseismically predicted slow rotation of the star; (3) comparisons of abundance patterns between KIC 11145123 and Am, Ap, and blue stragglers show that KIC 11145123 is neither an Am star nor an Ap star, but has abundances consistent with a blue straggler. We conclude that the remarkably long 100-d rotation period of this star is a consequence of it being a blue straggler, but both pathways for the formation of blue stragglers - merger and mass loss in a binary system - pose difficulties for our understanding of the exceedingly slow rotation. In particular, we show that there is no evidence of any secondary companion star, and we put stringent limits on the possible mass of any such purported companion through the phase modulation technique.

  10. Main Conclusions and Recommendations of International Conference on Topical Issues in Nuclear Installation Safety: Ensuring Safety for Sustainable Nuclear Development

    International Nuclear Information System (INIS)

    El-Shanawany, Mamdouh

    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

    Good afternoon. Before providing the closing remarks on behalf of the NEA, I would like to take this opportunity and make some personal reflections, if you allow me Mr. Chairman. I have had the opportunity to take part in the three workshops on public communication organised by the NEA. In the first one in Paris in 2000, representing my country, Spain, and in the two last ones in Ottawa in 2004 and Tokyo today, on behalf of the NEA. The topics for the three workshops follow a logical order, first the focus was on investing in trust in a time when public communication was becoming a big challenge for the regulators. Second, maintaining and measuring public confidence to assess how credible regulators are in front of the public; and finally here in Tokyo, transparency, which is a basic element to achieve trust and credibility. In my view, a regulatory decision has three main components, it has to be technically sound. legally correct and well communicated. The emphasis in the early years was in the technical matters, till legal issues became a key element to achieve the political acceptance from governments and local authorities. Finally the public communication aspects resulted into a major effort and challenge to achieve social acceptance. (author)

    General opening remarks to a conference on the effects of low-level radiation on man, exploring particularly areas where disagreements have most frequently been voiced. The author comments on two approaches: a) the study, stepwise of putative cause and effect chains, using models which are tested by comparing calculated and observed effects. b) the epidemiological approach by extensive correlative study of cause, correlations and effect. Attention is drawn to the confidence to be accorded to any quantitative theory supported by both approaches, and the need for further analysis if the approaches give different indications. (U.K.)

    The workshop has covered in a very interesting and complete way the basic physics issues to be addressed by the complementary facilities, in Canada and Japan, intended to explore the intensity-frontier of strong-interaction physics. Japan has its new KEK facilities and its future Japanese Hadron Project (JHP): Canada has its present TRIUMF laboratory and its future KAON Factory. Both JHP and KAON appear very near to final construction approval. The possibilities are very great for new joint programs between the two countries which can lead the world in the new strong interaction physics. These concluding remarks describe the general science basis and particularly the models for the internationalization of science needed to make these new collaborations thrive

It presents some (strictly marginal contrastive notes on expressing gender in English and Romanian, among which: genderization and gender neutrality, the problems posed by the usual definitions of gender (cf. sex, etc., the existence of the epicenes in English, the idea of neutralization of grammatical oppositions (cf. also the idea of “language economy”, the possible existence of the “0 gender” (cf. the 0 / ø article in English. Illustrative examples are given with respect to the alleged “sexist tradition” – as perceived by feminist lingustics –, followed by a set of prominent counterexamples (amply provided mainly by lexicography, fallacies and inconsistencies. The actual existence of gender-oriented languages (vs. “gender-neutral” languages is then addressed, as well as a group of issues relating to usage and language didactics, mainly idiosyncrasies, grammatical and miscellaneous problems.

    2013-01-01

    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)

    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 the fall of 2012, the subject of radiation protection in veterinary medicine was raised during the meeting of the HERCA Board. Issues with regard to this subject had been brought to the attention of HERCA by the European College of Veterinary Diagnostic Imaging (ECVDI). In October 2012, the Board decided to charge a small Task Force (TF) to further explore the issues in this field. This TF drew up a questionnaire which looked at the general radiation protection regulatory requirements in veterinary medicine applications of ionizing radiation. The results of this study showed large differences in the requirements applicable in the HERCA member countries. The TF also noticed the increasing use of more complex imaging procedures and of different radio-therapeutic modalities, which may imply greater risks of exposure of humans to ionising radiation. These results were presented during the HERCA Board meeting in Berlin, Germany and on which the Board decided to establish a Working Group on veterinary applications of ionising radiations (WG Vet). The main results of the Questionnaire 'National regulatory requirements with regard to veterinary medicine applications of ionising radiation' is attached in Appendix

    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.

    In Asia, Japan and the Republic of Korea have conducted similar studies but relying on statistical data and used inputs and outputs (I-O) methodology, utilizing on general macro-level data. In contrast, this study captures data directly through surveys using questionnaires, face-to-face interviews, case studies and focus group discussions. The impact of nuclear technology applications in Malaysia were evaluated both quantitatively and qualitatively. These impacts are then linked to a broader objective associated with technological development, namely wealth generation, knowledge generation and societal well-being. In the process of the study, users and practitioners of the technology highlighted issues and challenges faced by them. To cap the study, the level of activities of nuclear technology in Malaysia was benchmarked against those in Japan and the Republic of Korea. This chapter highlights the results of the study, the outcome of the study, followed by recommendations as response to issues and challenges raised by respondents, and finally the way forward for monitoring and charting further progress of nuclear technology in the country.

    The author's remarks are directed primarily at proposals that have been made that would substantially tort law with respect to radiation claims in order to ease the ability of claimants to recovery damages from defendants. The change would be based upon what had been assumed to be a ''scientific'' means of measuring the ''probability'' that exposure to ionizing radiation was the case of a cancer in a particular claimant. The remarks are divided into three parts: a summary description of the nuclear insurance pools, including the tort radiation claims filed against the pools; and a brief description of claims against the Federal Government and its contractors; an examination of the elementary principles of tort law, and an outline of the threat that has developed that would transform it into a hybrid social benefits program; and comment on the danger to the integrity of science when it is injected into the legislative process

    In the following, a few simple remarks on the evolution and properties of stellar clusters will be collected. In particular, globular clusters will be considered. Though details of such clusters are often not known, a few questions can be clarified with the help of primitive arguments. These are:- why are spherical clusters spherical, why do they have high densities, why do they consist of approximately a million stars, how may a black hole of great mass form within them, may they be the origin of gamma-ray bursts, may their invisible remnants account for the missing mass of our galaxy. The available data do not warrant a detailed evaluation. However, it is remarkable that exceedingly simple models can shed some light on the questions enumerated above. (author)

    Some remarks on the determination of the normal-superconductor phase boundary in random superconductive networks are made. A recently reported work by Soukoulis, Grest and Li which introduces weak links between nodes as these are removed in the site percolation problem is discussed. By the analysis of two simple geometries, it is shown that this procedure introduces spurious effects which mask the physical properties of the system. These affect in particular the field slope critical index and the sharpness of the normal-superconductor boundary. (Author)

  15. Seven remarkable days

    CERN Document Server

    This has been a truly remarkable seven days for CERN. Things have moved so fast that it has sometimes been hard to separate fact from fiction – all the more so since facts have often seemed too good to be true. It’s been a week of many firsts. Monday was the first time we’ve had two captured beams in the LHC. It’s the first time the LHC has functioned as a particle accelerator, boosting particles to the highest beam energy so far achieved at CERN. And it’s been a week in which we’ve seen the highest energy proton-proton collisions ever produced at CERN: our last hadron collider, the SPS was a proton-antiproton collider, a technically simpler machine than the LHC. This week’s successes are all the more remarkable precisely because of the complexity of the LHC. Unlike the SPS collider, it is two accelerators not one, making the job of commissioning nearly twice as difficult. I’d like to express my heartfelt thanks and congra...

  16. Remarkable resilience of teeth.

    2009-05-05

    Tooth enamel is inherently weak, with fracture toughness comparable with glass, yet it is remarkably resilient, surviving millions of functional contacts over a lifetime. We propose a microstructural mechanism of damage resistance, based on observations from ex situ loading of human and sea otter molars (teeth with strikingly similar structural features). Section views of the enamel implicate tufts, hypomineralized crack-like defects at the enamel-dentin junction, as primary fracture sources. We report a stabilization in the evolution of these defects, by "stress shielding" from neighbors, by inhibition of ensuing crack extension from prism interweaving (decussation), and by self-healing. These factors, coupled with the capacity of the tooth configuration to limit the generation of tensile stresses in largely compressive biting, explain how teeth may absorb considerable damage over time without catastrophic failure, an outcome with strong implications concerning the adaptation of animal species to diet.

    The authors report a study of energy biomass by considering its three main sources (forest, agriculture and wastes) and three energy needs (heat, fuel for transports, electricity) in the French national context. After having recalled the various uses of biomass (animal feeding, energy production, materials, chemical products), the authors discuss the characteristics of biomass with respect to other energy sources. Then, they analyse and discuss the various energy needs which biomass could satisfy: heat production (in industry, in the residential and office building sector), fuel for transports, electricity production. They assess and discuss the possible biomass production of its three main sources: forest, agriculture, and wastes (household, agricultural and industrial wastes). They also discuss the opportunities for biogas production and for second generation bio-fuel production

  2. Editorial - a remark you made

    Directory of Open Access Journals (Sweden)

    Yngve Nordkvelle

    2007-12-01

    Full Text Available ”A remark you made” is the title of a wonderful tune by the famous jazz-rock group “Weather Report”, issued on the influential “Heavy weather” LP some 30 years ago. In an age where planning and rationalizing is the main issue in most contexts, whether it’s a matter of studying, teaching, doing research or using a diet, “A remark you made” is a symbol of attending to the unplanned, unforeseen and often, unwanted. In most accounts on cognitive development one is overtly focused on the manageable, on the predictable and expected, and not so attentive to the opposite. “A remark you made” makes us think again and reconsider what might be of value, in what we otherwise might neglect. A remark made by Terry Anderson at a conference last year (2006 was rather telling. Anderson is the renown distance educator from Athabasca University, Alberta Canada, and editor of our fellow e-journal “The International Review of Research in Open and Distance Learning”. I recite it here totally from my own memory, and I have never approached him to have it verified, falsified or commented. That doesn’t matter in this context. Standing on the podium, he lowered his voice and asked if any Danes were present in the room. There weren’t! Then he explained that his argument might be presented differently with Danes present: “You see – Danes seem to think that learning alone is no longer possible!” That remark caused quite a good laugh, not the least because any comment – good or bad – about fellow Scandinavians generally is considered to be a good joke. But it was also a comment on how not only distance education, or open and flexible learning, but learning theory in general is driven by the sociocultural learning theory, - and according to Anderson, particularly so in Denmark! Our first contribution in this issue is about the theory of media theory developed by one of our editors: Lars Qvortrup. Lars is now the rector of the Danish

  4. Feasibility studies for final disposal of low and intermediate radioactive waste - summary with main conclusions and recommendations from three parallel studies. Report to the cross-departmental working group for preparing a decision basis for establishing a Danish radioactive waste disposal facility

    International Nuclear Information System (INIS)

    2011-05-01

    In 2003, the Danish Parliament in resolution No. B 48 on the dismantling of the nuclear facilities at Risoe gave consent to the government to begin preparation of a decision basis for a Danish final repository for low and intermediate level waste. As a result, a working group under the Ministry of Health and Prevention in 2008 prepared the report 'Decision basis for a Danish final repository for low and medium level radioactive waste'. In this report it was recommended to prepare three parallel preliminary studies: one about the repository concepts with the aim to obtain the necessary decision-making basis for selecting which concepts to analyze within the process of establishing a final repository, one on transportation of radioactive waste to the depot and one about regional mapping with the aim to characterize areas as suitable or unsuitable for locating a repository. The present report contains the main conclusions of each of the three parallel studies in relation to the further localization process. The preliminary studies suggest 22 areas, of which it is recommended to proceed with six in the selection process. The preliminary studies also show that all investigated storage concepts will be possible solutions from a security standpoint. However, there will be greater risks associated with depots near the surface, because they are more subjected to intentional or accidental intrusion. Overall, a medium deep repository will be the most appropriate solution, but it is also a more expensive solution than the near-surface repository. Both subsurface and the deep repositories may be reversible, but it is estimated to increase overall costs and may increase risk related to accidents. The preliminary studies establishes a set of conclusions and recommendations concerning future studies related to repository concepts and safety analyses, including in relation to the specific geology at the selected locations. The transportation studies show that radio

  13. Remarks on finite W algebras

    International Nuclear Information System (INIS)

    Barbarin, F.; Sorba, P.; Ragoucy, E.

    1996-01-01

    The property of some finite W algebras to be the commutant of a particular subalgebra of a simple Lie algebra G is used to construct realizations of G. When G ≅ so (4,2), unitary representations of the conformal and Poincare algebras are recognized in this approach, which can be compared to the usual induced representation technique. When G approx=(2, R), the anyonic parameter can be seen as the eigenvalue of a W generator in such W representations of G. The generalization of such properties to the affine case is also discussed in the conclusion, where an alternative of the Wakimoto construction for sl(2) k is briefly presented. (authors)

  17. Remark on Trautman's Radiation Condition

    International Nuclear Information System (INIS)

    Walker, M.

    1979-01-01

    The confusion about the boundary conditions for radiating systems formulated by Trautman are discussed. The confusion has mainly to do with where in space-time the conditions are to be imposed but also with what is it that the conditions are intended to guarantee. Imposing Trautman's conditions near future null infinity allows the existence of outgoing radiation; in order to exclude incoming radiation, they must be imposed near (or at) past null infinity. Since receding to infinity in spacelike directions means that one crosses all radiation, whether in- or outgoing, it makes no sense to impose the conditions at spatial infinity. If one were to impose fall-off of the electromagnetic field in flat space-time of 1/n at spatial infinity, then the field would contain finite energy. (Auth.)

  3. Single molecule microscopy and spectroscopy: concluding remarks.

    Science.gov (United States)

    van Hulst, Niek F

    2015-01-01

    Chemistry is all about molecules: control, synthesis, interaction and reaction of molecules. All too easily on a blackboard, one draws molecules, their structures and dynamics, to create an insightful picture. The dream is to see these molecules in reality. This is exactly what "Single Molecule Detection" provides: a look at molecules in action at ambient conditions; a breakthrough technology in chemistry, physics and biology. Within the realms of the Royal Society of Chemistry, the Faraday Discussion on "Single Molecule Microscopy and Spectroscopy" was a very appropriate topic for presentation, deliberation and debate. Undoubtedly, the Faraday Discussions have a splendid reputation in stimulating scientific debates along the traditions set by Michael Faraday. Interestingly, back in the 1830's, Faraday himself pursued an experiment that led to the idea that atoms in a compound were joined by an electrical component. He placed two opposite electrodes in a solution of water containing a dissolved compound, and observed that one of the elements of the compound accumulated on one electrode, while the other was deposited on the opposite electrode. Although Faraday was deeply opposed to atomism, he had to recognize that electrical forces were responsible for the joining of atoms. Probably a direct view on the atoms or molecules in his experiment would have convinced him. As such, Michael Faraday might have liked the gathering at Burlington House in September 2015 (). Surely, with the questioning eyes of his bust on the 1st floor corridor, the non-believer Michael Faraday has incited each passer-by to enter into discussion and search for deeper answers at the level of single molecules. In these concluding remarks, highlights of the presented papers and discussions are summarized, complemented by a conclusion on future perspectives.

    In 2003, the Danish Parliament in resolution No. B 48 on the dismantling of the nuclear facilities at Risoe gave consent to the government to begin preparation of a decision basis for a Danish final repository for low and intermediate level waste. As a result, a working group under the Ministry of Health and Prevention in 2008 prepared the report 'Decision basis for a Danish final repository for low and medium level radioactive waste'. In this report it was recommended to prepare three parallel preliminary studies: one about the repository concepts with the aim to obtain the necessary decision-making basis for selecting which concepts to analyze within the process of establishing a final repository, one on transportation of radioactive waste to the depot and one about regional mapping with the aim to characterize areas as suitable or unsuitable for locating a repository. The present report contains the main conclusions of each of the three parallel studies in relation to the further localization process. The preliminary studies suggest 22 areas, of which it is recommended to proceed with six in the selection process. The preliminary studies also show that all investigated storage concepts will be possible solutions from a security standpoint. However, there will be greater risks associated with depots near the surface, because they are more subjected to intentional or accidental intrusion. Overall, a medium deep repository will be the most appropriate solution, but it is also a more expensive solution than the near-surface repository. Both subsurface and the deep repositories may be reversible, but it is estimated to increase overall costs and may increase risk related to accidents. The preliminary studies establishes a set of conclusions and recommendations concerning future studies related to repository concepts and safety analyses, including in relation to the specific geology at the selected locations. The transportation studies show that radio

    Licensing regimes vary from country to country. When the license regime involves several regulators and several licenses, this may lead to complex situations. Identifying a leading organisation in charge of overall coordination including preparation of the licensing decision is a useful practice. Also, if a stepwise licensing process is implemented, it is important to fix in legislation decisions and/or time points and to identify the relevant actors. There is considerable experience in civil and mining engineering that can be applied when constructing a deep geological disposal facility. Specific challenges are, however, the minimization of disturbances to the host rock and the understanding of its long-term behavior. Construction activities may affect the geo-hydraulic and geochemical properties of the various system components which are important safety features of the repository system. Clearly defined technical specifications and an effective quality management plan are important in ensuring successful repository implementation which is consistent with safety requirements. Monitoring plan should also be defined in advance. The regulatory organization should prepare itself to the licensing review before construction by allocating sufficient resources. It should increase its competence, e.g., by interacting early with the implementer and through its own R and D. This will allow the regulator to define appropriate technical conditions associated to the construction license and to elaborate a relevant inspection plan of the construction work. After construction, obtaining the operational license is the most important and crucial step. Main challenges include (a) establishing sufficient confidence so that the methods for closing the individual disposal units comply with the safety objectives and (b) addressing the issue of ageing of materials during a 50-100 years operational period. This latter challenge is amplified when reversibility/retrievability is required

  12. Venturing into the private sector: Conclusion

    From the very beginning, HEU has been a government-to-government deal. And right fully so. These weapons were produced by the US and Russia over the course of the Cold War. The two superpowers should play the main role in their dismantlement. After all, these aren't cars or microcomputers we're talking about. They are weapons of mass destruction. One day, private business will profit from their dismantlement. But it is truly the responsibility of the US and Russian governments to accomplish the larger objective of the HEU deal: To destroy these weapons, once and for all. But if government can fulfill the role of moral overseer, there's no reason why the private sector should not be involved in implementing the plan. And there is no shortage of companies lining up for a piece of the business. The Russians are all ears. While a deal with the US is their main priority, they've spoken to a number of private companies about blending down and marketing the HEU. In recent months, several US companies have signed preliminary agreements with the Russians. But what actual business these agreements will lead to is very unclear

    Full Text Available The crisis in recent years took start in response to a crisis of the real estate market in the United States in 2007. The year 2009 has seen an economic crisis and between 2010 and 2011 it was known the spreading of the crisis sovereign debt and public finances of many countries. The financial markets failed in their main task: the allocation of risk. The products and services traded in the financial market are characterized by the immateriality and legal complexity. It means a high uncertainty degree and a high risk. Therefore is very important to protect the investors and this means: give them the right information, right legislation, market confidence and a product that respond to their needs. The crisis causes are: weaknesses in the regulatory, malfunction of the rating agencies, political errors and conflicts of interest. This means that we need: more rules, more capital, less debt, more transparency. The financial markets and the economy have always moved in harmony and savers have undertaken a countercyclical behavior, against trend or against the cycle and for investing in financial markets with the probability in favor we need a map that comes from the statistics.

  15. 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.

  16. Global Advisory Group: conclusions and recommendations.

    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

  1. Chemical physics of electroactive materials: concluding remarks.

    Science.gov (United States)

    Rutland, Mark W

    2017-07-01

    It is an honour to be charged with providing the concluding remarks for a Faraday Discussion. As many have remarked before, it is nonetheless a prodigious task, and what follows is necessarily a personal, and probably perverse, view of a watershed event in the Chemical Physics of Electroactive materials. The spirit of the conference was captured in a single sentence during the meeting itself."It is the nexus between rheology, electrochemistry, colloid science and energy storage". The current scientific climate is increasingly dominated by a limited number of global challenges, and there is thus a tendency for research to resemble a football match played by 6 year olds, where everyone on the field chases the (funding) ball instead of playing to their "discipline". It is thus reassuring to see how the application of rigorous chemical physics is leading to ingenious new solutions for both energy storage and harvesting, via, for example, nanoactuation, electrowetting, ionic materials and nanoplasmonics. In fact, the same language of chemical physics allows seamless transition between applications as diverse as mechano-electric energy generation, active moisture transport and plasmonic shutters - even the origins of life were addressed in the context of electro-autocatalysis!

  2. Remarks about the displaced spectra techniques

    International Nuclear Information System (INIS)

    Behringer, K.; Pineyro, J.

    1989-01-01

    In a recent paper a new method, called displaced spectra techniques, was presented for distinguishing between sinusoidal components and narrowband random noise contributions in otherwise random noise data. It is based on Fourier transform techniques, and uses the power spectral density (PSD) and a newly-introduced second-order displaced power spectra density (SDPSD) function. In order to distinguish between the two peak types, a validation criterion has been established. In this note, three topics are covered: a) improved numerical data for the validation criterion are given by using the refined estimation procedure of the PSD and SDPSD functions by the Welch method; b) the validation criterion requires the subtraction of the background below the peaks. A semiautomatic procedure is described; c) it was observed that peaks in the real part of the SDPSD function can be accompanied by fine structure phenomena which are unresolved in the PSD function. A few remarks are made about this problem. (author)

    The main aspects of fast reactor physics, presented in these lecture notes, are restricted to LMFBR's. The emphasis is placed on the core neutronic balance and the burn-up problems. After a brief description of the power reactor main components and of the fast reactor chronology, the fundamental parameters of the one-group neutronic balance are briefly reviewed. Then the neutronic burn-up problems related to the Pu production and to the doubling time are considered

  4. The end of a remarkable era

    CERN Multimedia

    2011-01-01

    An important era in particle physics is coming to an end: the US Department of Energy announced on Monday that it will not fund an extension to Tevatron running beyond 2011. It is a poignant moment for particle physics as we prepare to bid farewell to a machine that has changed our view of the Universe, and played a significant role in paving the way for the new era that is opening up with the LHC.   The Tevatron has been at the high-energy frontier of particle physics for over a quarter of a century. That’s a remarkable achievement by any account, and the physics results are there to prove it. As well as bringing us the discovery of the top quark in 1995, the Tevatron’s experiments have provided vitally important precision measurements covering the full spectrum of Standard Model physics, not to mention hints of what may lie beyond. With several months of running still to come, it would be a foolish gambler who bet against further new physics emerging before the Teva...

  5. Remarks on theoretical hot-atom chemistry

    International Nuclear Information System (INIS)

    Inokuti, Mitio

    1993-01-01

    The publication of the 'Handbook of Hot Atom Chemistry', following the earlier volume 'Recent Trend and Application', was a major milestone in physical chemistry. Theoretical treatments of hot atom chemistry must address two classes of problems. The first class concerns the individual collisions of hot atoms with other atoms or molecules. The second class concerns the description of the consequences of the many collisions of hot atoms and their chemical environment. Most of the remarks pertain to the problems of the first class. The central issue is the adiabaticity of nuclear motions versus electronic motions. To be precise, any atomic core motion should be mentioned rather than pure nuclear motion, because tightly bound core electrons are largely irrelevant to the chemistry. When nuclear motions are sufficiently slow, or for other reasons that can be regarded as adiabatic, the collision problem is basically straightforward, therefore, interatomic and intermolecular forces can be assumed, and their consequences for nuclear motions are calculable in principle. In the case of non-adiabaticity being important, much more difficult problems arise, and it is briefly discussed, and the work by Phelps is cited. (K.I.)

    1983-12-01

    The conceptual design of heavy ion fusion drivers has now reached a state, where the overall approach has become fairly clear. One design features an RF linac plus current and beam multiplication rings. The present remarks concern the assignment of multiturn injection, beam storage and bunching to an optimized number of rings and transport lines, as well as some criteria for their designs. The main parameter constraints are discussed, showing how they can be met, although there is little flexibility at the present stage of understanding and technology. A shortened version of this report is scheduled for presentation at the ''INS International Symposium on Heavy Ion Accelerators and Their Application to Inertial Fusion'' Tokyo, January 23-27 1984.

    2006-12-01

    Full Text Available Social Science Education as a subject field in schools is an intrinsic pluridisciplinary feature, whatever disciplines are included, however it may be organised and wherever it may be institutionalised. Civic education, economic education, social education and historical education each comprise several academic disciplines even if they are thought to be completely independent subjects. From the start on, disciplinarity and interdisciplinarity are on the agenda for any subject related to social science education and are one of its main problems. For these introductory remarks interdisciplinarity can be simply defined as relating two or more academic disciplines or school subjects to each other if this is done in a purposeful, systematic, explicit and reflective way. The overarching goal is to improve education that is to enhance students' understandings of the worlds and their abilities to act within and towards them. A relationship between disciplines or subjects which misses one or more of the four characteristics can be called pluridisciplinary or multidisciplinary (cf. Audigier 2006. In the following I first want to discuss some aspects of disciplinarity and interdisciplinarity at schools and at universities and the weakness of interdisciplinarity. I sketch some social science based ideas on the interrelationship between the subject structure of the academic world and the world of schools (3. and of some tendency to commonalities or even unification of social sciences and related competencies (4..

  9. Chandra Sees Remarkable Eclipse of Black Hole

    Science.gov (United States)

    2007-04-01

    A remarkable eclipse of a supermassive black hole and the hot gas disk around it has been observed with NASA's Chandra X-ray Observatory. This eclipse has allowed two key predictions about the effects of supermassive black holes to be tested. Just as eclipses of the Sun and moon give astronomers rare opportunities to learn about those objects, an alignment in a nearby galaxy has provided a rare opportunity to investigate a supermassive black hole. Illustrations of Black Hole Eclipse Illustrations of Black Hole Eclipse The supermassive black hole is located in NGC 1365, a galaxy 60 million light years from Earth. It contains a so called active galactic nucleus, or AGN. Scientists believe that the black hole at the center of the AGN is fed by a steady stream of material, presumably in the form of a disk. Material just about to fall into a black hole should be heated to millions of degrees before passing over the event horizon, or point of no return. The disk of gas around the central black hole in NGC 1365 produces copious X-rays but is much too small to resolve directly with a telescope. However, the disk was eclipsed by an intervening cloud, so observation of the time taken for the disk to go in and out of eclipse allowed scientists to estimate the size of the disk. Black Hole Animation Black Hole Animation "For years we've been struggling to confirm the size of this X-ray structure," said Guido Risaliti of the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass, and the Italian Institute of Astronomy (INAF). "This serendipitous eclipse enabled us to make this breakthrough." The Chandra team directly measured the size of the X-ray source as about seven times the distance between the Sun and the Earth. That means the source of X-rays is about 2 billion times smaller than the host galaxy and only about 10 times larger than the estimated size of the black hole's event horizon, consistent with theoretical predictions.

If u α (θ,x) denotes the optimal cost function, θ being the risk factor, then it is shown that lim { α to 0}α u α (θ,x)=ξ(θ) where ξ(θ) is the average on ]0,θ[ of the optimal cost of the (usual) infinite horizon risk-sensitive control problem

The purpose of this research is to highlight the main indicator that measures the total cost of a loan, namely the annual percentage rate (APR, because if we refer to an interest rate lower, at first glance that loan seems more advantageous, but at a closer look, taking into account the commissions charged by the bank, we see that the loan is more expensive compared to another, whose interest rate is higher.

  13. Recent advances in membrane materials: introductory remarks

    International Nuclear Information System (INIS)

    Ayral, A.

    2007-01-01

    A lot of separation operations are currently performed using membranes both for production processes and for environmental applications. The main part of the used membranes are organic membranes but for specific conditions of utilization inorganic or organic-inorganic membranes have been also developed. Among the applications for gas separation, some examples are the removal of hydrogen from ammonia synthesis gas, the removal of carbon dioxide from natural gas and air separation. Environmental considerations like massive scale air and water pollution and also the gradual rarefaction of fossil energy resources gave rise to the concept of sustainable growth and to related strategies like process intensification, the reuse of water and solvents at their point of use, hydrogen as energy vector (requiring H 2 production...)..Membranes will have a key part to play in the new technologies associated with these strategies. Intensive efforts of research and development are now engaged everywhere in the world to develop high performance membranes for those emerging applications. Membrane science is a multidisciplinary scientific and technological domain covering mainly materials science, physical chemistry, chemical engineering, modeling. This issue (Annales de chimie - Science des materiaux, 2007 Vol.32 N.2) provides a wide review of recent advances in membrane materials. It is based on the contributions of experts in different fields of membrane materials (organic, organic-inorganic hybrid, composite, carbon, metallic, ceramic; dense, porous, surface modified materials).

    2002-01-01

    In connection with methodological improvements of safety analyses, some effects of detail power distributions, that should be taken into account for the hot channel characteristics determination, have been studied. This determination concerns the whole channel power (power of the fuel rod) and its axial (along the channel) and radial (across the fuel pellet radius) distribution. The total power of the channel is studied from the point of possible restrictions for different numbers of main cooling loops in operation. For radial power distribution the effect of burnup has been studied and for axial distribution the effect of the control rod vicinity (its coupler part) has been evaluated. The DNBR and fuel temperatures have been the key safety parameters influenced by these hot channel characteristics and have been evaluated in this study (Authors)

    International Nuclear Information System (INIS)

    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

  17. Several remarks on the fuel cycle economy

    International Nuclear Information System (INIS)

    Roman Kubin; Rudolf Vespalec

    2007-01-01

    Present paper deals with some aspects influencing significantly cost of nuclear fuel and possibilities of its usage in optimal fuel cycle technology. Our discussion is focused on the phase of fuel procurement that means financial parts of the contract as well as its technical Appendices. Typically the fuel fabrication price is taken as the main economy indicator; nevertheless also many other financial and technical features of the contract must be taken into account in order to reach the best price of electricity sold into public energy grid. Our experience from several international tenders shows that the consistent complex of commercial and technical parameters of the contract is necessary to achieve optimal economic results and prepare proper conditions for advanced fuel cycle technology. Among those essential characteristics are payment conditions and schedule and extent of vendor's services and assistance to the operator. Very important role play also technical parameters, as safety and operational limits, influencing loading pattern quality and operating flexibility. Obviously also a level of operator's fuel cycle technology is a crucial point that is necessary for usage of technical quality of the fuel at the power plant. The final electricity price, produced by the plant, and uranium consumption are the only objective criteria to evaluate economic level of the fuel contract and the fuel cycle at all (Authors)

  18. Remarks on some rock neutron parameters

    International Nuclear Information System (INIS)

    Czubek, J.A.

    1984-01-01

    A method to calculate the thermal neutron parameters of rocks is given in the paper. It is based on a proper energy averaging of cross-sections for all rock matrix and rock saturating liquid constituents. The diffusion lengths in different lithologies in function of the variable rock porosity have been calculated. An influence of the thermal neutron spectrum on the shape of the porosity calibration curves for the dual spacing neutron method is shown. Magmatic rocks as a possible source of geothermal energy are now becoming a target of neutron loggings for the porosity determination. Here the knowledge of the slowing-down lengths is of great importance in the problem of the estimation of the calibration curves. A semi-analytical approach to get this parameter is given in the paper. It was found, as far as concerns the slowing-down of fast neutrons, that all magmatic rocks behave as sandstone with, however, different content of bound water in the rock matrix and different rock matrix density. Some neutron methods are based on the detection of epithermal neutrons. For theoretical considerations it is important to know the physical meaning of the registered signal. From the discussion of experimental data reported in the literature it seems that it is the slowing-down density that is the physical quantity being measured. This conclusion has a very important practical implication - the porosity calibration curves depend upon the slowing-down length alone and are independent of the slowing-down cross-section for epithermal neutrons

  19. Anticoagulant rodenticides and wildlife: Concluding remarks

    Rodents are known to affect human society globally in various adverse ways, resulting in a widespread demand for their continuous control. Anticoagulant rodenticides (ARs) have been, and currently remain, the cornerstone of rodent control throughout the world. Although alternative control methods exist, they are generally less effective. ARs work by affecting vitamin K metabolism, thereby preventing the activation of blood clotting factors and eventual coagulopathy. Since ARs are non-selective, their undoubted benefits for rodent control have to be balanced against the environmental risks that these compounds pose. Although they have been used for decades, pharmacokinetic and toxicokinetic data are mainly available for laboratory mammals and have concentrated on acute effects. Limited information is available on chronic exposure scenarios and for wildlife species. Important gaps exist in our understanding of the large inter- and intra-species differences in sensitivity to ARs, especially for non-target species, and in our knowledge about the occurrence and importance of sub-lethal effects in wildlife. It is clear that mere presence of AR residues in the body tissues may not indicate the occurrence of effects, although unequivocal assessment of effects under field conditions is difficult. Ante-mortem symptoms, like lethargy, subdued behaviour and unresponsiveness are generally not very specific as is true for more generic post-mortem observations (e.g. pallor of the mucous membranes or occurrence of haemorrhages). It is only by combining ante or post-mortem data with information on exposure that effects in the field may be confirmed. We do know however that a wide variety of non-target species are directly exposed to ARs. Secondary exposure in predators is also widespread although there is limited information on whether this exposure causes actual effects. Exposure is driven by ecological factors and is context specific with respect to spatial habitat configuration

    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

    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.

  19. 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 local organizers of the 4th BIFD (Bifurcations and Instabilities in Fluid Dynamics) Symposium held in Barcelona on 18-21 July 2011 would like to thank the editors of Fluid Dynamics Research for offering us the opportunity of publishing a peer-reviewed special issue of the journal with a selection of the contributions presented at this conference. We thank both the authors and the referees for working with us on the rather tight schedule necessary to release the issue within one year of the date of the conference. We also thank the invited speakers, B Eckhardt, L Tuckerman, and J M Vega, for contributing keynote papers to this special issue. The series of BIFD symposia started as a small workshop in Madeira, Portugal, in 2004 with no more than 20 participants. This number increased rapidly during the second and third symposia held in 2006 (Denmark) and 2009 (United Kingdom), with 40 and 110 participants, respectively. The 4th BIFD symposium has consolidated this event as one of the leading conferences in hydrodynamic stability, with nearly 200 participants from around the world. The main goal of this conference is to bring together scientists and engineers from different disciplines directly or indirectly related to fluid dynamics, bifurcation theory and hydrodynamic stability theory. The conference covered many research areas within the aforementioned fields, ranging from thermal, shear and centrifugal flows to biofluids, films, drops, viscoelastic flows and magnetohydrodynamics. The structure of the conference, with invited plenary talks and focused sessions, helped the participants find their home in the conference and share state-of-the-art knowledge within the field of hydrodynamic instabilities. The financial support from MICINN (Spanish Ministry of Science and Innovation, Grant no FIS2009-08065-E) and UPC (Universitat Politècnica de Catalunya) is greatly appreciated. The local organizers would also like to thank ETSAB (Barcelona School of Architecture

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

    International Nuclear Information System (INIS)

    Telle, K.

    2006-01-01

    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

    It has been hypothesized that variable stars may experience mass loss, driven, at least in part, by oscillations. The class of stars we are discussing here are the δ Scuti variables. These are variable stars with masses between about 1.2 and 2.25 M/sub θ/, lying on or very near the main sequence. According to this theory, high rotation rates enhance the rate of mass loss, so main sequence stars born in this mass range would have a range of mass loss rates, depending on their initial rotation velocity and the amplitude of the oscillations. The stars would evolve rapidly down the main sequence until (at about 1.25 M/sub θ/) a surface convection zone began to form. The presence of this convective region would slow the rotation, perhaps allowing magnetic braking to occur, and thus sharply reduce the mass loss rate. 7 refs

    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

  18. The no conclusion intervention for couples in conflict.

    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.

  19. The accident at the Harrisburg nuclear reactor - Interim conclusions

    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.

    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

    Barasch, Marc Ian

    2008-08-01

    Mind-body therapies are often portrayed in the literature as self-palliative, adjunctive, and complementary, but rarely as contributive to cure. Many physicians continue to view them as acceptable indulgences so long as they are harmless and the patient remains fully compliant with a standard treatment regimen. The possibility that such modalities might help drive the healing process itself is infrequently acknowledged. This article addresses the topic of such therapies, examining remarkable recoveries in cancer, and suggesting the need for a "Remarkable Recovery Registry" to expand the literature on these cases. The author discusses the importance of complementary alternative medicine, and emotional and pyschologic support in the treatment regimen, and the need for health care providers and patients to work together to provide the best emotional environment for the healing process.

    Analysis of a spin-rotation model illustrates how transitions between adiabatic channel states stem from the second, rather than from the first, rate of change of these states, provided that appropriate identification of channels and scaling of the independent variable are used. These remarks, like the earlier development of a post-adiabatic approach, aim at elucidating the surprising success of approximate separation of variables in the treatment of complex mechanical systems

    Hawking's area theorem is a fundamental result in black hole theory that is universally associated with the null energy condition. That this condition can be weakened is illustrated by the formulation of a strengthened version of the theorem based on an energy condition that allows for violations of the null energy condition. With the semi-classical context in mind, some brief remarks pertaining to the suitability of the area theorem and its energy condition are made.

    2016-08-01

    Full Text Available The global financial crisis and financial stability issues of the Eurozone countries have demonstrated that the total of financial knowledge and skills of the population that lets people make informed and efficient decisions is of utmost importance. Considering high social importance of financial education, it is necessary to develop a knowledge platform to increase the level of financial literacy. The results obtained in the process of assessment of the level of individual's financial literacy provide information on the factors, which reduce financial efficiency and cause unnecessary costs. Despite a vast body of international experience in the field of financial literacy assessment, one of the main problems is to develop a measuring instrument, which can ensure valid results and can be adapted to the socio-economic and demographic conditions of a definite country. Therefore, in 2015, academic personnel of the Department of Finance, Faculty of Engineering Economics and Management of Riga Technical University conducted research within the project «Enhancing Latvian Citizens' Securitability through Development of the Financial Literacy» and developed an instrument for assessment of the level of financial literacy, which can be used to evaluate financial knowledge of the Latvian citizens taking into consideration all components of financial literacy. The results are briefly described in the current paper.

    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.

    Mitrofanova, Lubov B.; Konovalov, Petr V.; Krylova, Julia S.; Polyakova, Victoria O.; Kvetnoy, Igor M.

    2017-01-01

    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

  4. 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

    Bangkok currently has enormous numbers of motorised vehicles. The number of motor vehicles registered in Bangkok in 1993 was about 2.6 million of which over 1 million were cars and around 1.1 million were motorcycles. The vehicle population is noticeably increasing at about 12% over the previous year, despite the traffic congestion which is nearly at gridlock. Overall average traffic speed in the Bangkok metropolitan area is around 10 km/h. However, during peak hours on some main roads in the central business area, the crawl rate is at 1-2 km/h, or only half walking pace. There are, however, several circumstances to be addressed before Bangkok can begin to overcome its air quality and congestion problems. The first is that many of the city`s transport planners that design transport projects, and the policymakers with investment authority appear to be caught in the same conventional transport planning paradigm as many other industrializing and industrialized countries. That paradigm, pioneered in the United States and exported to much of the world, defines the problems as a shortage of road space to meet demand for, private, vehicular mobility. The investment focus is almost exclusively on the construction of large road-based infrastructure to machines instead of people, while de-emphasizing other forms of transport such as rail, water, and non-motorized transport - even if they are a less expensive investment that can meet demand. The predominance of this paradigm results in a persistent myth held by many of Bangkok`s policymakers, transport and urban planners, financiers, and citizens. The myth is that the city does not have enough kilometers of roadways per person, and should focus on road and highway investment in order to solve their air quality and congestion problems.

  6. Failure of Magnetic Fluid Seals Operating in Water: Preliminary Conclusions

    Directory of Open Access Journals (Sweden)

    Matuszewski Leszek

    2017-06-01

    Full Text Available The article analyses properties of magnetic fluid seals installed in rotary sealing nodes which operate in the utility water environment. Seals of this type have been examined as a possible solution to the problem with ship manoeuvring propulsion sealing. The present analysis bases on laboratory durability tests of magnetic fluid seals exposed to longterm utility water loads, at different water pressures and shaft revolutions. The basic seal durability criterion was the number of revolutions made by the sealing node shaft until the appearance of water tightness loss (leakage. It was found that the main factor leading to the wear of the seal is the relative speed of the magnetic fluid with respect to that of the utility water, and this process is heavily affected by the pressure acting on the seal. The reported test results are presented in the form of diagrams showing the seal durability (time until water tightness loss as a function of rotational speed. The curves shown in the diagrams are regular, with two different rotational speed ranges: the highspeed range, when the tightness loss is relatively fast, and the low-speed range, with a clear tendency to prolong the seal lifetime. These diagrams were given the name of durability curves of the MF seal operating in water. The results of the performed tests suggest formal similarity between the experimental data distribution concerning tightness loss processes occurring in magnetic fluid seals operating in water environment and metal fatigue processes. The article proposes a preliminary simplified durability model to describe the examined phenomenon.

  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. This report presents the general conclusion and recommendations of the workshop and the summaries of the sessions

    various boundary conditions were investigated. The work involved a combination of integral and separate effect tests including molten-salt tests to investigate non-eutectic mixtures and the effects of stratification, extension of the material property database to allow interpretation and modelling of the experimental data. The CSNI decided to hold a seminar where the major outcome of the RASPLAV Project could be presented and discussed also in the context of other experienced activities on Severe Accidents. The objectives of the seminar are: - to review the experimental results of the RASPLAV Project; - to exchange information on complementary research; - to discuss the progress made on understanding severe accident progression; - to discuss the applicability to nuclear power plants and use of the results. The Seminar was intended to provide an in-depth review of the RASPLAV Project in terms of the technical capabilities, results and analyses produced during the project execution. The application of the results and their significance for power plant applications were addressed. Relevant results of the complementary research carried out at various laboratories were also presented. The seminar consisted of five sessions organised as follows: - Opening and overview; - Experimental results; - Theoretical Analyses; - Application and complementary research; - Conclusion

  9. Cosmological Gamma-Ray Bursts and Hypernovae Conclusively Linked

    Clearest-Ever Evidence from VLT Spectra of Powerful Event Summary A very bright burst of gamma-rays was observed on March 29, 2003 by NASA's High Energy Transient Explorer (HETE-II) , in a sky region within the constellation Leo. Within 90 min, a new, very bright light source (the "optical afterglow") was detected in the same direction by means of a 40-inch telescope at the Siding Spring Observatory (Australia) and also in Japan. The gamma-ray burst was designated GRB 030329 , according to the date. And within 24 hours, a first, very detailed spectrum of this new object was obtained by the UVES high-dispersion spectrograph on the 8.2-m VLT KUEYEN telescope at the ESO Paranal Observatory (Chile). It allowed to determine the distance as about 2,650 million light-years (redshift 0.1685). Continued observations with the FORS1 and FORS2 multi-mode instruments on the VLT during the following month allowed an international team of astronomers [1] to document in unprecedented detail the changes in the spectrum of the optical afterglow of this gamma-ray burst . Their detailed report appears in the June 19 issue of the research journal "Nature". The spectra show the gradual and clear emergence of a supernova spectrum of the most energetic class known, a "hypernova" . This is caused by the explosion of a very heavy star - presumably over 25 times heavier than the Sun. The measured expansion velocity (in excess of 30,000 km/sec) and the total energy released were exceptionally high, even within the elect hypernova class. From a comparison with more nearby hypernovae, the astronomers are able to fix with good accuracy the moment of the stellar explosion. It turns out to be within an interval of plus/minus two days of the gamma-ray burst. This unique conclusion provides compelling evidence that the two events are directly connected. These observations therefore indicate a common physical process behind the hypernova explosion and the associated emission of strong gamma

    various boundary conditions were investigated. The work involved a combination of integral and separate effect tests including molten-salt tests to investigate non-eutectic mixtures and the effects of stratification, extension of the material property database to allow interpretation and modelling of the experimental data. The CSNI decided to hold a seminar where the major outcome of the RASPLAV Project could be presented and discussed also in the context of other experienced activities on Severe Accidents. The objectives of the seminar are: - to review the experimental results of the RASPLAV Project; - to exchange information on complementary research; - to discuss the progress made on understanding severe accident progression; - to discuss the applicability to nuclear power plants and use of the results. The Seminar was intended to provide an in-depth review of the RASPLAV Project in terms of the technical capabilities, results and analyses produced during the project execution. The application of the results and their significance for power plant applications were addressed. Relevant results of the complementary research carried out at various laboratories were also presented. The seminar consisted of five sessions organised as follows: - Opening and overview; - Experimental results; - Theoretical Analyses; - Application and complementary research; - Conclusion.

    In conjunction with its 6. annual meeting, the WPDD in close co-operation with the FSC held a Topical session on 'Stakeholder Involvement in Decommissioning' on November 14, 2005. The session was attended by 36 participants totally representing 14 NEA member countries and 2 international organisations. Two keynote addresses were given at the Topical Session. The first one treated of what is needed for robust decisions and how to bring all stakeholders into the debate. In the second keynote address a summary was made on what have been said on stakeholder involvement in decommissioning during earlier meetings of the WPDD. The main part of the session was then devoted to views from different stakeholders regarding their role and their involvement. This part contained viewpoints from local communities (Kaevlinge in Sweden and Port Hope in Canada), authorities (Scottish Executive and CSNC) and operators (EDF from France and EWN from Germany). Case studies from the decommissioning of Dounrey in the UK and from Trojan and Main Yankee in the USA were presented in the end part of the Topical session followed by a summary and lessons learnt report by the Rapporteur. A detailed programme of the Topical session can be seen in Appendix 1

  12. [Conclusions. The precautionary principle: its advantages and risks].

    Science.gov (United States)

    Tubiana, M

    2000-01-01

    estimation of risks and benefits, the putting into proper perspective the possible risks that can be incurred from any given action, enables the main pitfalls of the precautionary principle to be avoided: the opposition to progress and the refusal of innovation, ever greater bureaucracy, and the waste of funds in the pursuit of an utopian "zero risk". Other drawbacks are more insidious: increased anxiety in the population, the manipulation of opinion by campaigns fomented by commercial or ideological interests, the influencing of practitioners and decision-makers to choose not the best solution but rather the one that will protect them from any future accusations. At the international level, efforts must be made to avoid that the precautionary principle be used for protectionist reasons. Nevertheless, the precautionary principle can have advantages, such as motivating decision-makers in the public or private sector to explain and quantify their reasoning, and to give objective information. However, the medical practitioner should not be tempted to ask that documents be signed as proof of the information given. This example underlines the possible dangers of the strict application of the law in certain cases and the importance of the role of jurisprudence. The precautionary principle will also impose new obligations on the State, which also must conform to the requirements of proportionality between risk and action, transparency and information in the field of care and health. The application of the precautionary principle will require good judgment because the way it is implemented will determine whether its outcome will be for the better or the worse. That is why it is indispensable that jurists, medical practitioners, and scientists work together so that the precautionary principle will be as precisely defined and codified as possible.

    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.

    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.

    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

    This module describes the main systems of low power (<2 MW) and higher power (≥2 MW) TRIGA reactors. The most significant difference between the two is that forced reactor cooling and an emergency core cooling system are generally required for the higher power TRIGA reactors. However, those TRIGA reactors that are designed to be operated above 3 MW also use a TRIGA fuel that is specifically designed for those higher power outputs (3 to 14 MW). Typical values are given for the respective systems although each TRIGA facility will have unique characteristics that may only be determined by the experienced facility operators. Due to the inherent wide scope of these research reactor facilities construction and missions, this training module covers those systems found at most operating TRIGA reactor facilities but may also discuss non-standard equipment that was found to be operationally useful although not necessarily required.

    The Boston Consulting Group has presented its remarks on the economic impact of the portfolio of measures issued from the 'Grenelle de l'Environnement' workshop that was held in France and involved people with a variety of backgrounds (government representatives, politicians, companies, professional syndicates, NGOs, scientists and university professors, etc.). These measures (covering sectors such as agriculture, biodiversity, wastes, renewable energies, transport, buildings, risk prevention, etc.) are said to potentially generate 450 billions Euros of economic activities and 600,000 jobs during 12 years. Their direct impacts on the environment would be a 14 percent reduction in greenhouse gases between 2010 and 2020. Concerning renewable energies, investment focusing is suggested

  20. Unbound color, prefaced by remarks on baryon spectroscopy

    International Nuclear Information System (INIS)

    Greenberg, O.W.

    Theoretical and experimental issues related to the possibility that color is unbound are surveyed. This implies that quarks, gluons and other particles carrying color can exist as isolated objects. It is surprisingly difficult to distinguish models with unbound color from those in which color is permanently confined. None-the-less, the present situation seems discouraging for unbound color because there is no unambiguous support for it and because the crucial prediction of formation of a colored gluon in e + e - collisions has been ruled out wherever sufficient data exists. The above survey is prefaced by remarks on the symmetric quark model for baryon spectroscopy

    Livingstone's second mission site on the shore of Lake Malawi suffers very high rates of consequential lightning strikes. Comprehensive interviewing of victims and their relatives in seven Traditional Authorities in Nkhata Bay District, Malawi revealed that the annual rate of consequential strikes was 419/million, more than six times higher than that in other developing countries; the rate of deaths from lightning was 84/million/year, 5.4 times greater than the highest ever recorded. These remarkable figures reveal that lightning constitutes a significant stochastic source of mortality with potential life history consequences, but it should not deflect attention away from the more prominent causes of mortality in this rural area.

    A discussion of the ingredients necessary to make predictions concerning single and double spin measurements in large p/sub perpendicular to/ inclusive processes is presented. Remarks are made as to what might be expected and what might be learned from such measurements. Various models for the production of large p/sub perpendicular to/ mesons have quite different spin structure and hence can be expected to give differing predictions. However, it is not possible at this time to make quantitative calculations, and it is possible (not probable) that the interesting spin observables will be negligibly small

    Denmark has played a substantial role in the history of Northern Europe. Through a nationwide scientific outreach initiative, we collected genetic and anthropometrical data from ∼800 high school students and used them to elucidate the genetic makeup of the Danish population, as well as to assess polygenic predictions of phenotypic traits in adolescents. We observed remarkable homogeneity across different geographic regions, although we could still detect weak signals of genetic structure reflecting the history of the country. Denmark presented genomic affinity with primarily neighboring countries with overall resemblance of decreasing weight from Britain, Sweden, Norway, Germany, and France. A Polish admixture signal was detected in Zealand and Funen, and our date estimates coincided with historical evidence of Wend settlements in the south of Denmark. We also observed considerably diverse demographic histories among Scandinavian countries, with Denmark having the smallest current effective population size compared to Norway and Sweden. Finally, we found that polygenic prediction of self-reported adolescent height in the population was remarkably accurate (R 2 = 0.639 ± 0.015). The high homogeneity of the Danish population could render population structure a lesser concern for the upcoming large-scale gene-mapping studies in the country.

  8. Escaping the flybottle: solipsism and method in Wittgenstein's Philosophical Remarks

    Directory of Open Access Journals (Sweden)

    Jônadas Techio

    2012-12-01

    Full Text Available The paper supports a dialectical interpretation of Wittgenstein's method focusing on the analysis of the conditions of experience presented in his Philosophical Remarks. By means of a close reading of some key passages dealing with solipsism I will try to lay bare their self-subverting character: the fact that they amount to miniature dialectical exercises offering specific directions to pass from particular pieces of disguised nonsense to corresponding pieces of patent nonsense. Yet, in order to follow those directions one needs to allow oneself to become simultaneously tempted by and suspicious of their all-too-evident "metaphysical tone" - a tone which, as we shall see, is particularly manifest in those claims purporting to state what can or cannot be the case, and, still more particularly, those purporting to state what can or cannot be done in language or thought, thus leading to the view that there are some (determinate things which are ineffable or unthinkable. I conclude by suggesting that in writing those remarks Wittgenstein was still moved by an ethical project, which gets conspicuously displayed in these reiterations of his attempts to cure the readers (and himself from some of the temptations expressed by solipsism.

    Li, Zhenqing; He, Chaoyu; Ouyang, Tao; Zhang, Chunxiao; Tang, Chao; Römer, Rudolf A.; Zhong, Jianxin

    2018-04-01

    We construct a class of two-dimensional (2D) phosphorus allotropes by assembling a previously proposed ultrathin metastable phosphorus nanotube into planar structures in different stacking orientations. Based on first-principles methods, the structures, stabilities, and fundamental electronic properties of these allotropes are systematically investigated. Our results show that these 2D van der Waals phosphorene allotropes possess remarkable stabilities due to the strong intertube van der Waals interactions, which cause an energy release of about 30 - 70 meV /atom , depending on their stacking details. Most of them are confirmed to be energetically more favorable than the experimentally viable α -P and β -P . Three of them, showing a relatively higher probability of being synthesized in the future, are further confirmed to be dynamically stable semiconductors with strain-tunable band gaps and intrinsic piezoelectricity, which may have potential applications in nanosized sensors, piezotronics, and energy harvesting in portable electronic nanodevices.

  13. Remarks on the Colonized Libido: Trying to Think beyond Patriarchy

    2004-01-01

    Full Text Available In these remarks I attempt to think through some of the consequences of the way we conceive and live our desires. I try to contrast those desires with both our idea of freedom and the way we usually understand nature. This takes me quickly to issues such as pornography, male identity and then to how we gain and preserve our self-esteem. This, in turn, takes me to issues that are somehow linked to the institutional and emotional structures of patriarchy under a regime of heterosexuality as a norm. I try to consider these issues from the point of view of someone who was trained within the practices and thoughts of masculinity and is bothered by the consequences of such training. I endeavour to find a way to rethink the colonization of our desires so that we can find paths to an exercise of our capacities of desire that could be somehow freer.

    emphasize one flood typology or one flood dynamic (for example flash floods are often over-represented than slow dynamic floods in existing databases). Thus, the selected criteria have to introduce a general overview of flooding risk in France by integrating all typologies: storm surges, torrential floods, rising groundwater level and resulting to flood, etc. The methodology developed for the evaluation grid is inspired by several scientific works related to historical hydrology (Bradzil, 2006; Benito et al., 2004) or extreme floods classification (Kundzewics et al. 2013; Garnier E., 2005). The referenced information are mainly issued from investigations realized for the PFRA (archives, local data),from internet databases on flooding disasters, and from a complementary bibliography (some scientists such as Maurice Pardé a geographer who largely documented French floods during the 20th century). The proposed classification relies on three main axes. Each axis is associated to a set of criteria, each one related to a score (from 0.5 to 4 points), and pointing out a final remarkability score. • The flood intensity characterizing the flood's hazard level. It is composed of the submersion duration, important to valorize floods with slow dynamics as flooding from groundwater, the event peak discharge's return period, and the presence of factors increasing significantly the hazard level (dykes breaks, log jam, sediment transport…) • The flood severity focuses on economic damages, social and political repercussions, media coverage of the event, fatalities number or eventual flood warning failures. Analyzing the flood consequences is essential in order to evaluate the vulnerability of society at disaster date. • The spatial extension of the flood, which contributes complementary information to the two first axes. The evaluation grid was tested and applied on the sample of 176 remarkable events. Around twenty events (from 1856 to 2010) come out with a high remarkability rate

  17. The remarkably high excitation planetary nebula GC 6537.

    Science.gov (United States)

    Aller, L H; Hung, S; Feibelman, W A

    1999-05-11

    NGC 6537 is an unusually high excitation point symmetric planetary nebula with a rich spectrum. Its kinematical structures are of special interest. We are here primarily concerned with the high resolution spectrum as revealed by the Hamilton echelle Spectrograph at Lick Observatory (resolution approximately 0.2 A) and supplemented by UV and near-UV data. These extensive data permit a determination of interstellar extinction, plasma diagnostics, and ionic concentrations. The photoionization models that have been used successfully for many planetary nebulae are not entirely satisfactory here. The plasma electron temperature of a photoionization model cannot much exceed 20,000 K, but plasma diagnostics show that regions emitting radiation of highly ionized atoms such as [NeIV] and [NeV] are much hotter, showing that shock excitation must be important, as suggested by the remarkable kinematics of this object. Hence, instead of employing a strict photoionization model, we are guided by the nebular diagnostics, which reveal how electron temperature varies with ionization potential and accommodates density effects. The predictions of the photoionization model may be useful in estimating ionization correction factor. In effect, we have estimated the chemical composition by using both photoionization and shock considerations.

  18. Remarkable reduction of thermal conductivity in phosphorene phononic crystal

    International Nuclear Information System (INIS)

    Xu, Wen; Zhang, Gang

    2016-01-01

    Phosphorene has received much attention due to its interesting physical and chemical properties, and its potential applications such as thermoelectricity. In thermoelectric applications, low thermal conductivity is essential for achieving a high figure of merit. In this work, we propose to reduce the thermal conductivity of phosphorene by adopting the phononic crystal structure, phosphorene nanomesh. With equilibrium molecular dynamics simulations, we find that the thermal conductivity is remarkably reduced in the phononic crystal. Our analysis shows that the reduction is due to the depressed phonon group velocities induced by Brillouin zone folding, and the reduced phonon lifetimes in the phononic crystal. Interestingly, it is found that the anisotropy ratio of thermal conductivity could be tuned by the ‘non-square’ pores in the phononic crystal, as the phonon group velocities in the direction with larger projection of pores is more severely suppressed, leading to greater reduction of thermal conductivity in this direction. Our work provides deep insight into thermal transport in phononic crystals and proposes a new strategy to reduce the thermal conductivity of monolayer phosphorene. (paper)

  19. Teletandem between French and Brazilian students: Some preliminary remarks

    Full Text Available ABSTRACT In its French-Brazilian version, the Teletandem Brazil project enables students from the University of Lille 3 (France and from the State University of São Paulo (Unesp, Brazil, to take part in online exchanges, based on the principles of autonomy and reciprocity. In this work, we will present some preliminary remarks on the construction of cultural identity representations by the students who took part in the project, from 2006 to 2012, the specificity of the exchanges we analyze being that most of the French students involved in them are third generation Portuguese. We will examine the consequences of the introduction of a third culture within exchanges which, linguistically speaking, are bilateral. The French students are often experiencing conflicting feelings toward Brazil and, similarly, the Brazilian students may have conflicting feelings towards Portugal and France. Our preliminary results show that the most successful linguistic exchanges occur when students face their own cultural identity with no feeling of superiority or inferiority.

  20. Directional selection in temporally replicated studies is remarkably consistent.

    2012-02-01

    Temporal variation in selection is a fundamental determinant of evolutionary outcomes. A recent paper presented a synthetic analysis of temporal variation in selection in natural populations. The authors concluded that there is substantial variation in the strength and direction of selection over time, but acknowledged that sampling error would result in estimates of selection that were more variable than the true values. We reanalyze their dataset using techniques that account for the necessary effect of sampling error to inflate apparent levels of variation and show that directional selection is remarkably constant over time, both in magnitude and direction. Thus we cannot claim that the available data support the existence of substantial temporal heterogeneity in selection. Nonetheless, we conject that temporal variation in selection could be important, but that there are good reasons why it may not appear in the available data. These new analyses highlight the importance of applying techniques that estimate parameters of the distribution of selection, rather than parameters of the distribution of estimated selection (which will reflect both sampling error and "real" variation in selection); indeed, despite availability of methods for the former, focus on the latter has been common in synthetic reviews of the aspects of selection in nature, and can lead to serious misinterpretations. © 2011 The Author(s).

  1. Remark on state vector construction when flavor mixing exists

    International Nuclear Information System (INIS)

    Fujii, K.; Shimomura, T.

    2006-01-01

    In the framework of quantum field theory, we consider the way to construct the one-particle state (with definite 3-momentum) when particle mixing exists, such as in the case of flavor-neutrino mixing. In the preceding report (Prog. Theor. Phys. 112, 901 (2004)), we have examined the structure of expectation values of the flavor neutrino charges (at time t) with respect to a neutrino-source state prepared at time t' (earlier than t). When there is no mixing, each of various contributions to the expectation value is equal, in its dominant part, to the transition probability corresponding to the respective neutrino-production process. On the basis of the assumption that such an equality holds also in the mixing case, we can find an appropriate form of one-flavor-neutrino state with 3-momentum and helicity. Along the same way, we examine the boson case when flavor mixing exists. We give remarks on the relation and difference between the ordinary and the present approaches to flavor oscillation

  2. Carbon nanocages: a new support material for Pt catalyst with remarkably high durability.

    2014-03-24

    Low durability is the major challenge hindering the large-scale implementation of proton exchange membrane fuel cell (PEMFC) technology, and corrosion of carbon support materials of current catalysts is the main cause. Here, we describe the finding of remarkably high durability with the use of a novel support material. This material is based on hollow carbon nanocages developed with a high degree of graphitization and concurrent nitrogen doping for oxidation resistance enhancement, uniform deposition of fine Pt particles, and strong Pt-support interaction. Accelerated degradation testing shows that such designed catalyst possesses a superior electrochemical activity and long-term stability for both hydrogen oxidation and oxygen reduction relative to industry benchmarks of current catalysts. Further testing under conditions of practical fuel cell operation reveals almost no degradation over long-term cycling. Such a catalyst of high activity, particularly, high durability, opens the door for the next-generation PEMFC for "real world" application.

    Eleonora Cappuccilli

    2015-06-01

    Full Text Available During the era of the English Revolutions and shortly after that, some spaces, albeit limited, of female visibility open up. Thanks to the window of opportunity caused by the collapse of censorship, the participation in the radical sects and in the Civil war, some remarkable women succeed in introducing themselves in the public sphere, shaping it since its very genesis. Moreover, analysing law institutions as jointure and feoffment, the attempt is to reconstruct some fragments of juridical female autonomy, which belie the total pervasiveness of coverture in the XVII century. As in private law, in public law women, in the role of queens, gain centrality: the principle of female authority, while safeguards the holding of the monarchical regime, destabilizes its patriarchal structure. Going through the works of Katherine Chidley, Margaret Cavendish, Damaris Masham and Mary Astell, the essay aims at reconstructing women's public voice, a voice which upsets the consolidated frames and subverts the established positions, questioning the same social hierarchies.

  5. Profitable thinning: dream or reality. Main conclusions from the FPP-study 'the influences of growing space regulation on the operational success of spruce management units'

    Johann, K; Pollanschuetz, J

    1980-01-01

    A computer simulation program (STAOET) was used to evaluate various thinning treatments for Picea abies. Treatment varied in: initial number of trees/ha (2500 vs. 5000); thinning intensity (weak, very strong, or graduated, i.e. early thinning strong, later weak); age (from 15 to 50 years) at first thinning; and age and number of later thinnings. Preliminary, final and total harvests were evaluated in terms of: volume (total, small timber, and log timber), mean diameter b.h., average volume/tree, and net value. Effects of varying site class index, rotation time, and timber cost/price structures (of small timber vs. log timber) were also studied. Low initial number of trees/ha and/or early reduction in tree number tended to give markedly higher final log timber volume, average diameter b.h., average volume/tree, and net value; resistance to snow damage also increased due to decrease in height/diameter ratio.

    The restoration of chiral symmetry in quantum chromodynamics as the temperature T and the chemical potential vertical stroke μ vertical stroke are increased is discussed qualitatively and using effective field theories. The latter are shown not to give reliable quantitative estimates. It is argued that a dilute gas of instantons cannot be the main dynamical agent responsible for the breakdown of chiral symmetry.

    In describing radiation damage processes in materials, the chemical rate theory proves to be the most effective mathematical method. The applicability, and even the validity, of this theory, which has been successfully applied in many other scientific fields, have been questioned by some authors. After rigorous mathematical analysis of the relevant rate equations and the corresponding self-consistent calculation of sink strengths, the main criticisms on this subject can be disproved

  13. On the normativity of human nature: some epistemological remarks.

    Science.gov (United States)

    Corradini, Antonella

    2003-04-01

    This paper examines the role played by the concept of human nature in ethical theory. The focus is on the epistemological problems that arise from application of this notion to the foundation of ethics. From this viewpoint, two theories, the neoscholastic and the neoclassical ones, are expounded, analyzed and compared. The aim is to highlight their opposite ways of relating the "ought-to-be" (of norms) to the "is" (of human nature). The conclusion is drawn that an adequate solution of the dispute depends on a correct interpretation of Hume's law. Reflection is conducted in the last section on the implications of metaethical discourse on human nature for applied ethics.

  14. The international INTRAVAL project. Summary and conclusions by the TVO/VTT Team

    1994-12-01

    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.)

    The Space Shuttle Main Engine (SSME) High Pressure Oxygen Turbopump (HPOTP) inducer cavitation study was initiated in the mid 1990s to support high synchronous vibrations. A Fastrac 60K Engine Oxygen Turbopump inducer cavitation study was started around the same time to support a blade deformation investigation. Super-synchronous rotating, attached synchronous, and pronounced subsynchronous flow oscillations were evident. Current thrusts in experimental work include characterization of loads induced by the various forms of cavitation inducted stabilities and measurements of cavitating turbopump dynamic transfer functions.

    2010-11-01

    The focus of the present study was to define the human plasma lipidome and to establish novel analytical methodologies to quantify the large spectrum of plasma lipids. Partial lipid analysis is now a regular part of every patient's blood test and physicians readily and regularly prescribe drugs that alter the levels of major plasma lipids such as cholesterol and triglycerides. Plasma contains many thousands of distinct lipid molecular species that fall into six main categories including fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, sterols, and prenols. The physiological contributions of these diverse lipids and how their levels change in response to therapy remain largely unknown. As a first step toward answering these questions, we provide herein an in-depth lipidomics analysis of a pooled human plasma obtained from healthy individuals after overnight fasting and with a gender balance and an ethnic distribution that is representative of the US population. In total, we quantitatively assessed the levels of over 500 distinct molecular species distributed among the main lipid categories. As more information is obtained regarding the roles of individual lipids in health and disease, it seems likely that future blood tests will include an ever increasing number of these lipid molecules.

    1995-01-01

    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

  18. Conclusions from some unusual events in the field of ionizing radiation in the German Democratic Republic

    International Nuclear Information System (INIS)

    Schuettmann, W.; Koenig, W.

    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)

  19. Remarks on flavor-changing neutral currents in walking technicolor

    International Nuclear Information System (INIS)

    Miransky, V.A.; Peris, S.; Raby, S.

    1993-01-01

    We point out that since the running coupling bar α(q 2 ) in walking technicolor (WTC) can be rather strong at the extended technicolor (ETC) scale q 2 ∼Λ ETC 2 , the standard consideration of flavor-changing neutral currents (FCNCs) in WTC based on the lowest order in perturbation theory in α is not fully conclusive. We reanalyze this problem and conclude that FCNCs can indeed be suppressed in WTC if ETC interactions are chosen in an appropriate way. The crucial point is that the factor of enhancement of the masses of pseudo Goldstone bosons in WTC is just that which is sufficient to suppress FCNCs. FCNCs in the so-called strong ETC are also briefly discussed

    2018-01-01

    Full Text Available Background. Undifferentiated anaplastic carcinoma rarely develops from chronic hyperthyroidism. Although acute hyperthyroidism can develop prior to anaplastic transformation, chronic hyperthyroidism was thought to be a protective measure against thyroid malignancy. Methods. A 79-year-old female presented acutely to the hospital with dyspnea. She had been taking methimazole for chronic hyperthyroidism due to toxic thyroid nodules, previously biopsied as benign. Upon admission, imaging showed tracheal compression, requiring a total thyroidectomy with tracheostomy for airway management. Results. Pathology demonstrated undifferentiated anaplastic thyroid carcinoma. The patient passed away shortly after hospital discharge. Despite treatment with methimazole for many years, abrupt enlargement of her toxic multinodular goiter was consistent with malignant transformation. Chronic hyperthyroidism and toxic nodules are rarely associated with thyroid malignancy, with only one previous report documenting association with anaplastic thyroid carcinoma. Conclusion. Progressive thyroid enlargement and acute worsening of previously controlled hyperthyroidism should promote concern for disease regardless of baseline thyroid function.

    International Nuclear Information System (INIS)

    Carlos, P.

    1982-10-01

    The principle of such facility is extremely simple, and consists merely of a set of very thin movable tungsten wires (40 μm < phi < 100 μm) which can be adjusted to intercept a small part of the main linac beam at the center of the BE deflection magnet. Incident electrons are thus scattered in all directions and in particular in the direction of the BE beam transport system, which can be attuned to the average energy of the scattered electrons to send a ''parasitic '' electron beam in the BE experimental area. This parasitic electron beam facility is currently used to operate the low energy tagged photon facility. In order to obtain an intense monochromatic tagged photon beam with a 100% duty cycle a simple procedure is used. It consists of feeding a small stretcher ring equipped with an internal gas jet target with a single electron pulse of width δt delivered every T seconds

    When consumers feeding on a resource spend time in avoiding high risks of predation, the predator functional response declines with predator density. While this is well established, less attention has been paid to the dependence of the consumer functional response on predator density. Here we show...... how the separation of behavioral and ecological timescales allows one to determine both responses starting from an explicit behavioral model. Within the general set-up considered in this paper, the two functional responses can tend toward Holling type II responses when consumers react only weakly...... to predation. Thus, the main characteristics of the standard Rosenzweig-MacArthur tritrophic food chain (logistic resource and Holling type 11 consumer and predator) remain valid also when consumers have weak antipredator behavior. Moreover, through numerical analysis, we show that in a particular...

  4. Public meeting on radiation safety for industrial radiographerss: remarks, questions and answers at five NRC regional meetings

    International Nuclear Information System (INIS)

    1978-11-01

    Over the past several years thenumber of radiation overexposures experienced in the radiography industry has been higher than for any other single group of NRC licensees. To inform radiography licensees of NRC's concern fo these recurring overexposure incidents, NRC staff representatives met with licensees in a series of five regional meetings. At these meetings the staff presented prepared remarks and answered questions on NRC regulations and operations. The main purposes of the meetings were to express NRC's concern for the high incidence of overexposures, and to open a line of communication between the NRC and radiography licensees in an effort to achieve the common goal of improved radiation safety. The remarks presented by the staff and subjects discussed at these meetings included: the purpose, scope, findings and goals of the NRC inspection program; ways and means of incorporating safety into radiography operations; and case histories of overexposure incidents, with highlights of the causes and possible preventions. At each of the regional meetings the staff received a request for a copy of the prepared remarks and a consolidation of the questions and answers that were discussed. This document includes that information, and a copy is being provided to each organizaion or firm attending the regional meetings. Requests for other copies should be made in accordance with the directions printed inside the front cover of this document

    2015-01-01

    The IAEA has been entrusted by the international community to conduct verification activities and implement safeguards. The work of the IAEA in this important area contributes to the establishment of a robust global nuclear non-proliferation regime, which is one of the essential elements as we seek to promote peace and security around the world. Being the only international organisation with this special mandate, the integrity and the credibility of the Agency are therefore vital as the international community needs to know that they can trust that the safeguards conclusion for a particular country has been drawn by the Agency only after, amongst others, a meticulous inspection in the field and a thorough and objective evaluation of all safeguards-relevant information, free of all political influence. All these points have also been highlighted by DDG Varjoranta in his keynote address at the beginning of the technical plenary. So, the question is, which is the topic of this panel discussion, how does the IAEA ensure consistency in the area of safeguards? What lessons can be drawn from the past in order to further enhance consistency in safeguards implementation? In light of the changing nuclear landscape, and in particular the increasing complexity of nuclear facilities, what steps may be envisaged to ensure the objectivity and consistency of safeguards implementation

    Pereira, S. H.; A. Pinho S., S.; Hoff da Silva, J. M.

    2014-08-01

    Recent results on the dynamical stability of a system involving the interaction of the ELKO spinor field with standard matter in the universe have been reanalysed, and the conclusion is that such system does not exhibit isolated stable points that could alleviate the cosmic coincidence problem. When a constant parameter δ related to the potential of the ELKO field is introduced in the system however, stable fixed points are found for some specific types of interaction between the ELKO field and matter. Although the parameter δ is related to an unknown potential, in order to satisfy the stability conditions and also that the fixed points are real, the range of the constant parameter δ can be constrained for the present time and the coincidence problem can be alleviated for some specific interactions. Such restriction on the ELKO potential opens possibility to apply the ELKO field as a candidate to dark energy in the universe, and so explain the present phase of acceleration of the universe through the decay of the ELKO field into matter.

  10. Some remarks on the taxonomy of the Plumerioideae (Apocynaceae

    Directory of Open Access Journals (Sweden)

    A. J. M. Leeuwenberg

    1983-11-01

    Full Text Available The family of the Apocynaceae is usually subdivided into two subfamilies, the Plumerioideae with the type genus Plumeria from tropical America, and the Apocynoideae, often named Echitoideae, with the type genus Apocynum from North America. These subfamilies show two characters which are more or less diagnostic for all members. However, since the taxonomists have built up the present scheme of the Apocynaceae, phytochemists have observed that many plants belonging to the Plumerioideae contain alkaloids, and that many representatives of the Apocynoideae contain glycosides. Some of the alkaloids, e.g. those of Catharanthus, Rauvolfia and Voacanga, and some of the glycosides, e.g. those of Funtumia and Strophanthus are of medicinal interest. In the present paper, the arrangement of the genera within the Plumerioideae is mainly that of Pichon (1949, 1950, 1953a, 1953b. He subdivided all tribes, except the Tabernaemontaneae, into subtribes, which is an excellent concept according to the present author. The latter, however, does not always agree with the delimitation of the genera. For instance, he does not accept the sinking of Acokanthera under Carissa, especially as the plants belonging to these genera show great differences in architecture (Hallé & Oldeman 1970; Hallé, Oldeman & Tomlinson, 1978, but he sinks several genera maintained by Pichon, e.g.  Ervatamia under Tabernaemontana (1976.

  11. Critical remarks on Bruno Thuring's polemic against Einstein.

    Science.gov (United States)

    Kerschbaum, F.; Lackner, K.; Posch, T.

    2005-08-01

    Bruno Thüring (1905-1989) was among those scientists who joined the campaign against Einstein's Theories of Relativity which was undertaken in the name of so-called "German Physics". Thüring served as director of Vienna's University Observatory between 1940-45; hence, we present biographical information on his scientific and administrative activities in Vienna, partly based on interviews with time-witnesses. It is one of Thüring's basic convictions that Einstein's work cannot be understood without an analysis of the developments of physics and philosophy in the 19th century. While this is true generally, Thüring's account of these developments is rather superficial. For example, Thüring considers Kant's idea of the a priori status of geometry as a wholly sufficient epistemological foundation of mechanics, while both post-Kantian idealism and positivism were a mere backdrop to the development of knowledge - a view which can hardly stand critical examination. Concerning the impact of Einstein's theories on physics, Thüring argues that the principles of special and general relativity be nothing else but arbitrary decisions (as opposed to real insights). Hence these principles would never be verified or falsified by any experiment. The Michelson-Moreley experiment, e.g., would not prove the principles of special relativity. Thüring considers Einstein's interpretation of this experiment as premature and as an arbitrary judgement on a very particular and subaltern phenomenon which would not justify the conclusion that the velocity of the Earth with respect to the luminiferous aether be immeasurable by just any experimental technique.

  12. The remarkable Red Rectangle: A Stairway to Heaven?

    Science.gov (United States)

    2004-05-01

    responsible for the striking red colour of the Rectangle is not yet clear, but it is likely that they are some kind of hydrocarbon formed in the cool outflows from the central star. Another remarkable feature of the Red Rectangle, visible only with the superb resolution of the Hubble telescope, is the dark band passing across the central star. This is the shadow of a dense disc of dust that surrounds the star and obscures it from direct view. The light we see streams out along the axis of the disc, and is scattered towards us by dust particles. Astronomers have found that the central star is actually a close pair of stars orbiting each other with a period of about 10.5 months. Interactions between these stars have probably caused the ejection of the thick dust disc that obscures our view of the binary. The disc then funnels subsequent dust and gas outflows out along its axis, forming the bizarre bi-conical structure we see as the rung of the Red Rectangle. The reasons for these fresh periodic ejections of more gas and dust remain unknown. The Red Rectangle was first discovered during a rocket flight in the early 1970s, in which astronomers were searching for strong sources of infrared radiation. This infrared source lies about 2300 light-years from Earth in the direction of the constellation Monoceros. Stars surrounded by clouds of dust are often strong infrared sources because the dust is heated by the starlight and then re-radiates long-wavelength red light. Studies of HD 44179 with ground-based telescopes revealed a rectangular shape in the dust surrounding the star at the centre, leading to the name 'Red Rectangle', coined in 1973 by astronomers Martin Cohen and Mike Merrill. This image was made from observations taken on 17-18 March 1999 with Hubble’s Wide Field Planetary Camera 2.

  13. Campylobacter jejuni sequence types show remarkable spatial and temporal stability in Blackbirds

    Full Text Available Background: The zoonotic bacterium Campylobacter jejuni has a broad host range but is especially associated with birds, both domestic and wild. Earlier studies have indicated thrushes of the genus Turdus in Europe to be frequently colonized with C. jejuni, and predominately with host-associated specific genotypes. The European Blackbird Turdus merula has a large distribution in Europe, including some oceanic islands, and was also introduced to Australia by European immigrants in the 1850s. Methods: The host specificity and temporal stability of European Blackbird C. jejuni was investigated with multilocus sequence typing in a set of isolates collected from Sweden, Australia, and The Azores. Results: Remarkably, we found that the Swedish, Australian, and Azorean isolates were genetically highly similar, despite extensive spatial and temporal isolation. This indicates adaptation, exquisite specificity, and stability in time for European Blackbirds, which is in sharp contrast with the high levels of recombination and mutation found in poultry-related C. jejuni genotypes. Conclusion: The maintenance of host-specific signals in spatially and temporally separated C. jejuni populations suggests the existence of strong purifying selection for this bacterium in European Blackbirds.

    2012-10-23

    The introduction of drug-eluting stents and advances in catheter techniques have led to increasing acceptance of percutaneous coronary intervention (PCI) as a viable alternative to coronary artery bypass graft (CABG) for unprotected left main disease. Current guidelines state that it is reasonable to consider unprotected left main PCI in patients with low to intermediate anatomic complexity who are at increased surgical risk. Data from randomized trials involving patients who are candidates for either treatment strategy provide novel insight into the relative safety and efficacy of PCI for this lesion subset. Herein, we review the current data comparing PCI with CABG for left main disease, summarize recent guideline recommendations, and provide an update on technical considerations that may optimize clinical outcomes in left main PCI.

    Last year a number of main coolant pumps in Belgian nuclear power plants were decontaminated. A new method has been developed to reduce the time taken for decontamination and the volume of waste to be treated. The method comprises two phases: Oxidation with permanganate in nitric acid and dissolution in oxalic acid. The decontamination of main coolant pumps can now be achieved in less than one day. The decontamination factors attained range between 15 and 150. (orig.) [de

  17. Rim formation and fission gas behaviour: some structure remarks

    International Nuclear Information System (INIS)

    Spino, J.; Papaioannou, D.; Ray, I.; Baron, D.

    2002-01-01

    In high burn-up LWR nuclear fuel an increase of the Xe-mobility is observed in the rim region according to EPMA. This often coincides with an increase of the local porosity and the grain subdivision of the material in regions around the pores. The restructuring does not always imply disappearance of the prior grain boundaries. This seems to occur in a final step. Micro-XRD studies also show a contraction of the fuel lattice in the rim zone, reflecting mainly the release of accumulated stresses during irradiation, via reordering of defects and defect complexes, including sub-grain formation and displacement of Xe traps. The lattice contraction is not measurable when the fraction of restructured areas is low and the prior grain structure still remains. Nevertheless, in such a case, even the Xe signal by EPMA is observed to decrease, anticipating the displacement of Xe inside the grains, probably towards cavities. However, the quantitative proportion of Xe in matrix and pores can not be given by EPMA. This is confirmed by TEM examinations, showing still plenty of gas bubbles inside restructured grains, in spite of the low Xe signal detected by EPMA. An alternative determination therefore appears necessary. The fission gas release (FGR) behaviour of the rim zone seems then to depend basically on the efficiency of gas retention in its porosity. The closed character of these pores and the low percolation probability derived from the high pore to grain size ratio anticipate a low incidence of open porosity. Also, mechanical tests suggest a low pore interconnection probability by microcracking. However, at very high local burn-ups (>150 GWd/tM), too high porosity values are determined compared to the values derived from immersion density and solid swelling, suggesting the potential existence of open channels. Also, abnormally high porosity values by quantitative metallography might arise from grain pullout during sample preparation. Here, a rough estimation of the release

    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".

    2014-09-01

    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

  1. Evaluating Behaviorally Oriented Aviation Maintenance Resource Management (MRM) Training and Programs: Methods, Results, and Conclusions

    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.

    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.

    The Fermilab Main Ring control system has been operational for over sixteen years. Aging and obsolescence of the equipment make the maintenance difficult. Since the advent of the Tevatron, considerable upgrades have been made to the controls of all the Fermilab accelerators except the Main Ring. Modernization of the equipment and standardization of the hardware and software have thus become inevitable. The Tevatron CAMAC serial system has been chosen as a basic foundation in order to make the Main Ring control system compatible with the rest of the accelerator complex. New hardware pieces including intelligent CAMAC modules have been designed to satisfy unique requirements. Fiber optic cable and repeaters have been installed in order to accommodate new channel requirements onto the already saturated communication medium system. 8 refs., 2 figs

    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

  15. ONKALO - Main drawings in 2007

    International Nuclear Information System (INIS)

    2008-05-01

    The first overall site characterisation programme for a Finnish repository of spent nuclear fuel was introduced in 1982. This programme already suggested that the site confirmation for a detailed repository design and safety assessment should include characterisation performed in an underground rock characterisation facility (URCF). This idea was confirmed during the detailed site characterisation. International views have also emphasised the importance of underground characterisation before the final decision to construct the repository is taken. The underground rock characterisation facility (ONKALO) is excavated at Olkiluoto in the municipality of Eurajoki. ONKALO should be constructed to allow characterisation work for site confirmation without jeopardising long-term safety of the repository site. It should also be possible to link ONKALO later to the repository as to a part of it. The construction of ONKALO was started in 2004 and will be completed in 2014. The characterisation work has started in ONKALO and will focus on the disposal depth. In the main drawings stage, ONKALO was described at the level of detail needed for a construction permit in 2003. This meant description of the location, final structures and final systems. This summary report describes the development of design to updated main drawings in 2007 at the same level of detail (no temporary arrangements are described). The main changes are the added exhaust air shaft and advancing the controlled area's inlet air shaft to the ONKALO phase. Also the layout and the depth of the characterisation levels have been updated according to the current bedrock information. Some buildings on the surface will house sets of equipment directly connected with underground facility and this equipment is described in this report. No buildings or other equipment are described in this report, because they are not directly connected with the underground facility. The main element of ONKALO is a system of

We discuss the empirical correlates of the so-called “main sequence” associated with the quasar Eigenvector 1, its governing physical parameters and several implications on our view of the quasar structure, as well as some luminosity effects associated with the virialized component of the line emitting regions. We also briefly discuss quasars in a segment of the main sequence that includes the strongest FeII emitters. These sources show a small dispersion around a well-defined Eddington ratio value, a property which makes them potential Eddington standard candles.

  19. 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

    It is own goal to realize commercial tokamak fusion plants by the middle of this century. In this special issue, the problems that should be solved for the goal, the ITER's role as the way of solution and the development programs that could not be verified in ITER are described. Acquisition of marketability for practical use of fusion plants is not easy. However, it is expected that compactification of plants, realization of high-performance and low cost are proceeded by some new ideas. So we think that there is a good feasibility for the acquisition. In about 2100, the primary energy of maximum 20% will be supplied if the economic rationality is satisfied enough, and thus there is big significance in aiming at this. In addition, the characteristics such as inexpensiveness and stability in long-term use, security, environmental safety are also important elements. In the future, we will have to obtain fruitful results through participation to ITER, and it is essential to carry steadily out the projects to activate domestic research and development. For helping to understand this special issue, the summary of fusion development by tokamaks is attached as an appendix. (T.O.)

    1996-01-01

    About twenty years ago, the leaders of the National Cancer Institute (NCI) decided to start a new branch in the Clinical Oncology Program of the Division of Cancer Treatment. That new entity was named the Clinical Pharmacology Branch (CPB), and its first leader was a brilliant, young, promising investigator named Bruce A. Chabner. Chabner was educated at Yale and Harvard, and appeared to have an extraordinary grasp of novel concepts that were being developed in the emerging area of cancer chemotherapy. What the NCI leaders did not fully appreciate at the time was that they had just given birth to one of the most extraordinary careers in academic medicine. From the early seventies through the early eighties, Bruce Chabner developed a strong laboratory program that was based on scientific discovery and on the development of new talent. The CPB focused on new drug development, elucidation of drug mechanism(s) of action, and the development of new ways to use drugs that were already available. Concurrent with this laboratory effort was active participation in the development of clinical treatment regimens for Hodgkin's disease, non-Hodgkin's lymphoma, and other malignancies. Individuals who trained under Chabner are now cancer center directors, department heads, laboratory chiefs, and hold many other high-profile positions. From 1981 to 1995 Bruce Chabner was Director of the Division of Cancer Treatment (DCT) of the NCI. In that capacity he was Scientific Director of the Intramural Program within DCT, and he had oversight responsibility for the direction of extramural studies that were funded through the NCI, which were focused on the development of new treatments for human malignant disease. The NCI has five divisions for which the NCI Director has ultimate responsibility. While working with one NCI Director from 1981 to 1988, and with another from 1988 to 1995, and during the transition year of 1988, Bruce Chabner provided stability for the DCT while many changes were occurring throughout the five divisions of the NCI. How does one assess the impact of a career on a discipline such as cancer treatment? It's not easy! Each of the articles contributed to this tribute were written by a person who trained directly with Bruce Chabner, or was otherwise directly impacted by Bruce's guidance. As can be seen from the list of contributors to these Proceedings, each individual has made major contributions to the area of cancer treatment in his or her own right. However, Bruce's contribution to cancer treatment goes far beyond the individuals he trained. The many thousands of human lives who have benefited from his efforts cannot be accurately estimated, because his contributions have been so wide-ranging, as indicated below. Being "Scientific Director" is similar in a number of ways to being a football quarterback. One of those ways is that when things go well the quarterback may get a little too much credit, and when things go not-so-well the quarterback may get too much blame. However, it is the quarterback who "calls the plays." With that in mind, a partial list of the accomplishments of the Intramural Program of the DCT while Bruce Chabner was "quarterback" includes the following: * The first human retroviruses, HTLV-1 and HTLV-2, were discovered and shown to be directly linked to the development of specific human malignancies. * Adoptive immunotherapy for human cancer was developed, offering exciting new additions to the anticancer armamentarium. * Paclitaxel (Taxol®) was developed, and shown to be the most important new anticancer agent in the past two decades. * The human genes responsible for the development of several specific malignancies were discovered, such as those for kidney cancer. * Development of blood tests to detect HIV-tainted blood. * Treatment strategies for pediatric AIDS were developed. * The AIDS Drug Development Program within the NIH was established. * New drugs for the treatment of AIDS and AIDS-related conditions were developed. * The only three drugs to date that have been specifically approved for the treatment of AIDS-AZT, DDI, and DDC-were developed under the guidance of the DCT, with Bruce Chabner as Scientific Director. * The first clinical trials conducted with each of these agents-AZT, DDI, and DDC-were performed in the Intramural Program of the DCT. * Concurrently, many of the exciting findings reported by the National Surgical Adjuvant Breast and Bowel Project over the past 10 years (as well as other cooperative groups) were a direct result of the strong support shown by Bruce Chabner during his tenure as Director of the Division of Cancer Treatment. Further, the list above does not include his personal labortory and clinical accomplishments, some of which are: * Development of the principles of use of important antimetabolites, such as methotrexate. * Elucidation of biochemical pathways affected, and the mechanisms of action, of antifols and other antimetabolites. * The conduct of seminal studies in the clinical staging of non-Hodgkin's lymphomas, using laparoscopy as a primary tool. * Important contributions to the development of multiagent regimens in the clinical treatment of lymphomas, and of Hodgkin's disease. * Developed and is editor of the textbook which is considered to be the primary reference source for anticancer chemotherapeutic agents [1]. With all of these accomplishments, his career is long from over. Having just become the Medical Director of the Cancer Center at the Massachusetts General Hospital, Bruce Chabner is uniquely poised to have an even more far-reaching impact on a discipline in which he has played such a strong seminal role. This author was never a postdoctoral fellow in Bruce Chabner's laboratory. However, more than any other single person, he has played a central role in my professional development. I know of many others for whom the same statement would be true. It is a pleasure for me to witness the launching of the second phase of an already tremendous career.

    Rosen, L.

    1989-01-01

    There appeared to be unanimity on the proposition that energy and environmental problems are following a course which threatens to overwhelm all nations and all peoples unless we take corrective actions and soon. There also was unanimity on the thesis that many of the global problems require international cooperation and collaboration on a scale never before experienced and that this is a matter of survival. Nuclear energy, in its most horrible form, not only brought an end to a terrible war but has also served to discourage war between the major powers for more than 40 years, the longest such period in all of modern history, which dates back about 350 years. Nuclear arsenals, obnoxious though they are, have helped buy time for the world to put its political establishment on a path which makes global war less and less probable. This must continue but, in addition, we now need to buy time (50-100 years) to develop environmentally benign energy sources that are affordable and that will alleviate the instabilities imposed by islands of affluence in a sea of despair. This conference reinforces belief that nuclear energy can help mightily to solve that problem. In fact, it appears to be one of very few realistic options available to us. But we will fail in making this option available if we do find a way to increase the literacy of the world's people, and especially their leaders, about environmental matters generally and about the nuclear-energy option in particular. We must find ways to provide factual information with impeccable honesty and high credibility. I am hopeful that the information generated by this conference, widely disseminated, will help to do that and also to foster such conferences in the future

    This paper is an introduction to the Tau Charm Factory workshop. To establish a firm scientific basis for future Tau Charm Factory plans one has to address the following two questions: (1) To what extent can and will work at other machines cover work that a Tau Charm Factory could do? Conversely (2) What are the required minimum parameters of a Tau Charm Factory which can do unique physics five years hence and beyond? This workshop has been organized to generate some preliminary answers in response to these two questions. Thus this Workshop is neither simply a scientific Workshop on the one hand or a planning session for specific machines on the other; rather it is something in between. During the workshop, specific plans or proposals for a Tau Charm Factory will be presented, but no attempt will be made to arrive at a consensus in response to such plans

    The papers, all indexed separately, have been taking stock of the overall position as regards the development of fast reactors in Europe, the USSR, the USA and Japan. Good technical progress has been made with the development of this major source of electrical power for the next century. In Europe, there are two large prototypes operating, Phenix and PFR. There is also a 1200 MW e demonstration reactor (Superphenix), which is now continuing with its commissioning programme after the interruption caused by the leak from the fuel storage vessel. The Soviet Union is pressing ahead with its programme; in the USA FFTF has given outstanding reliability and in Japan the construction of Monju is going well and is on schedule for criticality in 1992. There has been general agreement on the basic economic and performance parameters of the fast reactor and its fuel cycle. In particular, after the first of a kind costs have been met, fast reactor and PWR generating costs are likely to be broadly similar, in the absence of large increases in uranium prices. However, the future of fast reactors is uncertain and the reasons for this are discussed. (author)

    A predominant aim of planetary exploration is to discover as much as possible about the origin of the Solar System. The conference papers and discussion are considered with this in mind. Comparative studies of surface features show that the 'geologies' of the terrestrial planets and the Moon and other large satellites are quite different. This is due in part to the presence or absence of water in various states. Other differences mentioned are the manifestations of tectonism and the chemical composition of these bodies. One paper suggests that interstellar molecules must have entered directly into the formation of the earth. Models for the major planets are proposed and satellites considered. The trend is to show that the formation of a satellite system must be a different process from the formation of a planetary system. Finally the formation of planets in pairs is noted. (U.K.)

    I feel that the changes which have taken place in science in the last few years open up new possibilities, about which I should like to say a few words. In 1951 we began work on thermonuclear reactions in the confident belief that we would solve the problem with a rush and immediately. I was assigned the task of ensuring that our future thermonuclear reactor would not get too much out of hand. It was like the story of the man who wished to invent a perpetual motion machine and had taken out a patent on a method for keeping it under control. This attitude stemmed from the successes in developing ''explosive thermonuclear reactors'', a task which was achieved within a very short period of time, leaving physicists with the impression that they could do everything - and do it fast. However, experience soon showed that here we had a scientific rather than a technological problem and that it would be necessary to study in detail the physics of plasmas - which we have now been doing for over ten years.

    The search for periodic or quasi-periodic variations in the solar constant through the analysis of climatic and meteorological data has proved elusive. The reason is evident: the atmosphere is a wet gas with much energy stored as latent heat and is in complex interaction dynamically and thermally with the oceans and land areas. The instabilities, what we call the weather, cause not only day-to-day but also year-to-year variations so great that small changes due to fluctuations of the energy input from the Sun may be masked. Yet, as the seasonal changes of solar energy falling on each hemisphere result in such obvious effects, it should not be impossible to detect in the climatic records much smaller changes in the total global input of heat energy into the atmosphere, especially if these are cyclical, by integrating out short-term fluctuations. Terrestrial phenomena which might be associated with solar behaviour such as tree-ring growth, drought, heavy rains, air temperature are of great interest. There is evidence from these sources of longer cycles of solar activity which may have a period of between 100 and 200 years but with the data available this is difficult to prove. The issue is complicated by variations in geomagnetic activity. A new source of information on solar activity is the spectrum of 14 C variations from during the past millenia from tree rings and this has prompted further studies of variations in the sun and climate to be undertaken.

    Where are the gaps in our current knowledge and what research is needed? One of my concerns was whether those of us in the radiation protection community have been thinking along the same lines as people in the field of toxicology. I think what has been evident that the problems and issues are very similar. Very evident common problems are those of extrapolation of observed toxic effects at high doses to predictions of effects at low doses; of the applicability of information obtained from one animal species to another; the public pressures to define risk (perhaps not pressures to define this goal as much as to define what is safe); the problems of multiple exposures; and the lack of money and resources to do all the things that it seems should be done. These are all problems familiar to us in the radiation protection community

    There has been recent increased interest in the development of and investment in the Canadian coal industry because of rising natural gas prices and increased demand for coking coal. Several new Canadian producers have commenced mining and shipping coal. Premium hard coking coal prices have risen, from $40 US in 2000 to above $100 US per tonne in 2006. The resource sector is challenged by higher energy costs, increasing transportation costs, problems with equipment and parts procurement, and the recruitment and retention of skilled mining employees. Mineral exploration and development has risen seven-fold in British Columbia since 2001, where the province now offers a competitive business and taxation environment as an incentive to resource development. Coal represents 40% of British Columbia's mining revenue.

    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.

    2017-03-01

    Full Text Available Objectives: The current investigation was carried out to determine the cytotoxic and the antimicrobial activities of methanolic extracts of Plumbago zeylanica. Methods: The stems, leaves, and whole plants were air dried and extracted with methanol by using a Soxhlet extractor for 72 hours at 55 - 60°C. The antimicrobial activities were determined from the zones of inhibition, which were measured by using the agar well diffusion method, and the cytotoxicity assays were performed using the 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT assay method. Results: The methanolic extracts of the stem and the leaves of Plumbago zeylanica were tested against six bacterial species and nine fungal species, and both extracts showed antimicrobial activity in a dose-dependent manner. The leaf extract of Plumbago zeylanica showed maximum antimicrobial activity against both Staphylococcus aureus sub sp aureus and Fusarium oxysporum. The stem extract was found to be more antimicrobial against the Pseudomonas aeruginosa and the Penicillium expansum species. MTT assays were used to test the cytotoxicity of the whole plant extract in the HCT-116 and the K-562 cell lines, and that extract was shown to have weak cytotoxicity in both cell lines. Conclusion: In the present study, the methanolic stem extracts of Plumbago zeylanica were found to possess remarkable antibacterial activities against many human and agricultural pathogens. The extracts were also found to possess significant antifungal activities, but the antifungal activities were less than the antibacterial activities. Finally, the extracts were found to have weak cytotoxicities in the HCT-116 and the K-562 cell lines.

    This special issue contains papers related to the 2009 Thomas Young Centre Workshop at University College London 'Accessing large length and time scales with accurate quantum methods', in celebration of Professor Michael Gillan's 65th birthday. Mike Gillan won the 2006 Institute of Physics Dirac Medal and Prize, the citation reading: 'For his contributions to the development of atomic-scale computer simulations, which have greatly extended their power and effectiveness over an immense range of applications'. This rightly highlights Mike's seminal work on materials modelling, but misses out some of the many other areas he has enriched. After taking his PhD at the Department of Theoretical Physics, Oxford University, Mike went as a post-doc to Minneapolis. He then joined the Statistical Physics Group in the Theoretical Physics Division, Harwell, where he stayed for over 20 years, with a brief interlude in Saclay. In the late 1980s, Mike made a transition to become Professor of Physics at the University of Keele, where he stayed for a decade until University College London was fortunate in being able to tempt him to join the Condensed Matter and Material Physics Group, where there was already a significant materials modelling initiative. Over the years, Mike has made many important contributions, some with impact on other areas of science, others with significance in technology areas such as nuclear safety. Thus, he developed a form of quantum transition-state theory, generalizing Eyring's well-known classical transition-state theory to the case of quantum particles, such as hydrogen, diffusing in condensed matter. He pioneered quantum methods for calculating defect energetics in solids, and then molecular processes on surfaces. He synthesised these approaches into very general ways to calculate thermodynamic free energies of condensed matter from first principles, drawing on his early experience of statistical physics. These methods led to rapid advances in the study of matter under extreme conditions, as in the Earth's core. A further powerful development has been his input to linear-scaling quantum techniques for the properties of very large complex systems. In recent years, his attention has shifted towards increasing accuracy, touching areas such as quantum Monte Carlo and hierarchical quantum chemical techniques. In this journal issue, we have papers which both reflect topics from the workshop and address a number of areas which are directly in Mike's interests or which have been influenced by his work or assistance. There are papers addressing accuracy in quantum simulations [1-5], methods for applying quantum techniques to large systems [6, 7] and applications of quantum simulations to important problems [8-10]. We also have a viewpoint on magnetism in oxides and carbon [11], prompted by Mike's innovative work on oxides. References [1] Nolan S J, Bygrave P J, Allan N L and Manby F R 2010 J. Phys.: Condens.

    MIRI ('Mid InfraRed Instrument') is the combined imager and integral field spectrometer for the 5-29 micron wavelength range under development for the James Webb Space Telescope JWST. The flight acceptance tests of the Spectrometer Main Optics flight models (SMO), part of the MIRI spectrometer, are completed in the summer of 2008 and the system is delivered to the MIRI-JWST consortium. The two SMO arms contain 14 mirrors and form the MIRI optical system together with 12 selectable gratings on grating wheels. The entire system operates at a temperature of 7 Kelvin and is designed on the basis of a 'no adjustments' philosophy. This means that the optical alignment precision depends strongly on the design, tolerance analysis and detailed knowledge of the manufacturing process. Because in principle no corrections are needed after assembly, continuous tracking of the alignment performance during the design and manufacturing phases is important. The flight hardware is inspected with respect to performance parameters like alignment and image quality. The stability of these parameters is investigated after exposure to various vibration levels and successive cryogenic cool downs. This paper describes the philosophy behind the acceptance tests, the chosen test strategy and reports the results of these tests. In addition the paper covers the design of the optical test setup, focusing on the simulation of the optical interfaces of the SMO. Also the relation to the SMO qualification and verification program is addressed.

  7. Proclus' Elaboration of Platonic Remarks on the Problem of Evils, and their Relation to Divine Providence and Efficiency

    2014-06-01

    Full Text Available Although there is not a fully developed theory of evil in Plato, some various remarks are interspersed throughout his dialogues which provided the main materials for subsequent Platonists to elaborate a systematic doctrine of evil. Proclus is the most distinguished philosopher of the later Neoplatonism whose view became authoritative within the School and thus is most representative of the Neoplatonic doctrine of evil. By a critical assessment of the antecedent theories of evil, Proclus attempts to give a monistic interpretation of Platonic remarks on the problem of evil. According to his explanation, the higher degrees and principles of Being are only and purely good and are not the causes of evils but the good things for all things alone. Evils, however, exist necessarily but only among particular beings in a relative, parasitic, accidental way and dependent upon the good. The parasitic accidental existence of evil does not have a real efficient cause. It arises due to an asymmetry between the activities of the several faculties or powers of a complex particular being. Moreover, the existence of evil is so mixed with and dependent upon the good that despite its opposition to the good, contributes, in its own manner, to the fulfillment of goodness of the whole Universe, being thus reconcilable with Divine Providence and Efficiency.

    We used ESME to simulate transition crossing in the Main Ring (MR). For the simulations, we followed the MR 29 cycle used currently for bar p production with a flat top of 120 GeV. In Sect. II, some inputs are discussed. In Sect. III, we present simulations with space charge turned off so that the effect of nonlinearity can be studied independently. When space charge is turned on in Sect. IV, we are faced with the problem of statistical errors due to binning, an analysis of which is given in the Appendices. Finally in Sects. V and VI, the results of simulations with space charge are presented and compared with the experimental measurements. 7 refs., 6 figs

    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.

    2012-01-01

    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

    1998-01-01

    The Synchronous Timing System is designed to provide sub-nanosecond timing to instrumentation during the acceleration of particles in the Main Injector. Increased energy of the beam particles leads to a small but significant increase in speed, reducing the time it takes to complete a full turn of the ring by 61 nanoseconds (or more than 3 rf buckets). In contrast, the reference signal, used to trigger instrumentation and transmitted over a cable, has a constant group delay. This difference leads to a phase slip during the ramp and prevents instrumentation such as dampers from properly operating without additional measures. The Synchronous Timing System corrects for this phase slip as well as signal propagation time changes due to temperature variations. A module at the LLRF system uses a 1.2 Gbit/s G-Link chip to transmit the rf clock and digital data (e.g. the current frequency) over a single mode fiber around the ring. Fiber optic couplers at service buildings split off part of this signal for a local module which reconstructs a synchronous beam reference signal. This paper describes the background, design and expected performance of the Synchronous Timing System. copyright 1998 American Institute of Physics

    2017-06-01

    Full Text Available The present article is a position paper aiming to initiate a professional debate related to the aspects related to the urban dysfunctions leading to the wear of the residential areas. The paper proposes a definition of the wear process, identify the main causes leading to its occurrence and propose a number of solutions to neutralise the dysfunctions. The three wearing phases of residential areas components are emphasized, exploring their lifecycle. In order to perform the study of urban wear, the status of the residential areas components can be established and monitored, and also the variables of the function that can mathematically model the specific wear process may be considered. The paper is considered a first step for the model adjustment, to be tested and validated in the following steps. Based on the mathematical method and model, there can be created, in a potential future research, the possibility of determining the precarity degree for residential areas/neighbourhoods and cities, by minimising the subjective component of the analyses preceding the decision for renovation or regeneration.

  2. Research in auditing: main themes

    Full Text Available ABSTRACT The passage of the Sarbanes-Oxley Act (SOX was a turning point in auditing and in auditors practice for the academic world. Research concerning the characterization of academic production related to auditing is in its third decade. Its analysis is accomplished by means of definition of keywords, abstracts or title, and information on thematic association within the academic production itself in auditing is undisclosed. In order to revise this gap in auditing literature, this study identified the main themes in auditing and their association in post-SOX era by analyzing the content of objectives and hypothesis of 1,650 publications in Web of Science (2002-2014. The findings in this study extended those from the study by Lesage and Wechtler (2012 from 16 auditing thematic typologies to 22. The results demonstrate that the themes audit report & financial statement users, corporate governance, audit market, external audit, socio-economic data of the company, international regulation, and fraud risk & audit risk were the most addressed in the publications about auditing. Corporate governance has a broader association with the other themes in the area. Future researches may use these themes and relate them to the methodologies applied to audit studies.

    A remarkable systemic error which was unknown in past long time has been indicated. The error appears in the calibration methods of determining activity of 238 U is used with γ-spectrometer with high resolution. When the γ-ray of 92.6 keV as the characteristic radiation from 238 U is used to determine the activity of 238 U in natural environment samples, the disturbing radiation produced by external excitation (or called outer sourcing X-ray radiation) is the main problem. Because the X-ray intensity is changed with many indefinite factors, it is advised that the calibration methods should be put away. As the influence of the systemic errors has been left in some past research papers, the authors suggest that the data from those papers should be cited carefully and if possible the data ought to be re-determined.

Some aspects about the nesting biology of the potter wasp Hypodynerus andeus (Packard, 1869 are reported for the first time. Observations were carried out at the Azapa valley, coastal desert of northern Chile. A total of sixty nests were collected and examined, each composed by 1-14 cells, most of them found attached to concrete lamp posts. The only preys recorded in the cells were Geometridae (Lepidoptera caterpillars and the presence of the parasitoid Anthrax sp. (Diptera, Bombyliidae was also recorded. A number of arthropods belonging to different groups, mainly spiders, were found occupying empty nests.

    Full Text Available Alopecia areata (AA is a chronic, autoimmune disease. The main symptom is massive hair loss, localized or diffuse, in the scalp and the whole body. However, nails may also be involved, and brittleness, fragility and pitting can be signs of nail dystrophy in AA patients. Here, we report the case of a male patient with AA refractory to various treatments, including oral, topical and intralesional corticosteroids, immunosuppressants, cyclosporin and PUVA (oxoralen plus ultraviolet light, all interrupted due to side effects. The patient’s nails had erythematous blotches (striated lunulae with regular and superficial pitting as well as fragility (trachyonychia, and he could no longer play the guitar because of these symptoms. With patient consent, we introduced tofacitinib (5 mg twice daily, which resulted in remarkable improvements not only regarding hair regrowth but also nail changes, with function recovery within 10 months.

    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.

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.)

    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.

    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.

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

    Science.gov (United States)

    Wagner, Nils-Frederic; Northoff, Georg

    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.

    2015-04-01

    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.

    Fourteen tasks were identified by UNC Nuclear Industries for evaluating the life expectancy of N Reactor structures, systems and components in the Balance of Plant portion of the Production Assurance Program. A Westinghouse Hanford Company (WHC) evaluation team was assigned to each of these fourteen tasks. A uniform set of criteria was used by all teams in evaluating the problems that may be encountered during the extended plant operating lifetime. The overall conclusion is that extended life to those Balance of Plant components and systems studied can be achieved. Problems with the potential for compromising that conclusion are identified, and feasible solutions are provided

    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)

    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.

    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)

    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

    Belief-bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. 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...

    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 ...

  12. Regret and Responsibility Resolved? Evaluating Ordóñez and Connolly's (2000) Conclusions.

    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.

    1979-01-01

    A survey is given of the state and prospects for the scientific researches to be carried out at the largest charged particle accelerators now under construction. The fundamental problems of the elementary particle physics are considered which can be solved on the base of experiments at high-energy accelerators. The problems to be solved involve development of the theory of various quark number, accurate determination of the charged and neutral intermediate vector boson masses in the Weinberg-Salam theory, the problem of production of t-quark, W -+ - and Z deg bosons, Higgs mesons and investigation of their interactions, examination of quark and lepton spectra, studies on the effects of strong interactions. As a result of the investigations on hadrons at maximum momentum transfers, the data on space-time structure at short distances can be obtained. It is emphasized that there are no engineering barriers to the construction of such accelerators. The main problem lies in financial investment. A conclusion is drawn that the next generation of accelerators will be developed on the base of cooperation between many countries [ru

  15. How often do sensitivity analyses for economic parameters change cost-utility analysis conclusions?

    2004-01-01

    There is limited evidence about the extent to which sensitivity analysis has been used in the cost-effectiveness literature. Sensitivity analyses for health-related QOL (HR-QOL), cost and discount rate economic parameters are of particular interest because they measure the effects of methodological and estimation uncertainties. To investigate the use of sensitivity analyses in the pharmaceutical cost-utility literature in order to test whether a change in economic parameters could result in a different conclusion regarding the cost effectiveness of the intervention analysed. Cost-utility analyses of pharmaceuticals identified in a prior comprehensive audit (70 articles) were reviewed and further audited. For each base case for which sensitivity analyses were reported (n = 122), up to two sensitivity analyses for HR-QOL (n = 133), cost (n = 99), and discount rate (n = 128) were examined. Article mentions of thresholds for acceptable cost-utility ratios were recorded (total 36). Cost-utility ratios were denominated in US dollars for the year reported in each of the original articles in order to determine whether a different conclusion would have been indicated at the time the article was published. Quality ratings from the original audit for articles where sensitivity analysis results crossed the cost-utility ratio threshold above the base-case result were compared with those that did not. The most frequently mentioned cost-utility thresholds were $US20,000/QALY, $US50,000/QALY, and $US100,000/QALY. The proportions of sensitivity analyses reporting quantitative results that crossed the threshold above the base-case results (or where the sensitivity analysis result was dominated) were 31% for HR-QOL sensitivity analyses, 20% for cost-sensitivity analyses, and 15% for discount-rate sensitivity analyses. Almost half of the discount-rate sensitivity analyses did not report quantitative results. Articles that reported sensitivity analyses where results crossed the cost

    The set-up of a relativistic constituent quark model in four dimensions is one of the outstanding problems in particle physics. For the time being this involves a great deal of model building which, very probably, will not change in the near future. In this paper we shall offer some general remarks which might help putting such models into shape. Most of the earlier attempts are found controversial. In particular, a conventional quark constituent interpretation could not be recovered. (orig.) [de

  6. Workshop on iodine aspects of severe accident management. Summary and conclusions

    International Nuclear Information System (INIS)

    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 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

    In September 2001, Deep Space 1 (DS1) completed a high-risk and flawless encounter with comet 19P/Borrelly. Its data provide a detailed view of this comet and offere surprising and exciting insights. With this successful conclusion of its extended mission, DS1 undertook a hyperextended mission. Following this period of extremely agressive testing, with no further technology or science objectives, the mission was terminated on December 18, 2001, with the powering off of the spacecraft's trnasmitter, 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.

    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)

    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.

  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)

    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.

    The increase in the surface luminosity associated with the well-known helium shell flashes might be a trigger for an early mass ejection process. This phenomenon has a significant influence on the global statistical features of the Mira variables as well as on the mass distribution of white dwarfs. The above situation is analysed by adopting the luminosity behaviour during helium shell flashes presented by previous authors to a dynamical picture for the asymptotic giant branch stars. The main observational implications are described and discussed. (author)

    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.)

    A number of countries consider sedimentary rocks to host a nuclear waste repository, the isolation potential of which relies mainly on very low permeabilities of those formations. To establish confidence in models used in future safety assessments, INTRAVAL working group 3 analysed three test cases addressing the relevant processes which govern the transport of radionuclides in the host formation as well as in the overburden. The WIPP 1 test case studied the flow of brine from a bedded salt formation into open excavations under pressure gradients. Experiments carried out at the Waste Isolation Pilot Plant in New Mexico, USA, were carefully analysed and compared to numerical simulations. The Mol test case studied the main transport mechanisms for solutes through clay. Experiments with radioactive tracers were carried out for several years at the Mol underground laboratory, Belgium, and compared to numerical simulations. The Gorleben test case studied the influences of salt leached from a salt dome on the groundwater flow field by density variations. Measurements from a pumping test and of salt content with depth collected at boreholes throughout the investigation area at Gorleben, Germany, were compared with the results of analytical and numerical studies.

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

    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

  4. Status of maintenance in the US nuclear power industry 1985. Volume 1. Findings and conclusions

    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

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

    Directory of Open Access Journals (Sweden)

    2012-12-01

    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.

  6. Conclusive evidence of abrupt coagulation inside the void during cyclic nanoparticle formation in reactive plasma

    2016-01-01

    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.

    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.

    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

    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

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

    Since 2011, the SOPHIE project has accumulated evidence regarding the influence of social and economic policies on population health levels, as well as on health inequalities according to socioeconomic position, gender, and immigrant status. Through comparative analyses and evaluation case studies across Europe, SOPHIE has shown how these health inequalities vary according to contexts in macroeconomics, social protection, labor market, built environment, housing, gender equity, and immigrant integration and may be reduced by equity-oriented policies in these fields. These studies can help public health and social justice advocates to build a strong case for fairer social and economic policies that will lead to the reduction of health inequalities that most governments have included among their policy goals. In this article, we summarize the main findings and policy implications of the SOPHIE project and the lessons learned on civil society participation in research and results communication.

    Autopsy findings in patients with bladder carcinoma, treated by combined operation and radiotherapy, revealed tendencies of tumor spread as well as complications and late effects of radiotherapy. In 24.5% of the cases tumor tissue was found within the bladder and in 30.5% within the minor pelvis. Metastases were found in 24.1% in iliac lymph nodes, in 21.3% in abdominal lymph nodes. Liver, lungs, bones, and kidneys are main organs for hematological metastasizing. Little or undifferentiated carcinomas and squamous cell carcinomas showed a greater tendency to metastasize than highly and medium-differentiated ureteral carcinomas. The least radiotherapeutical complications and late effects were found in a fractionation with daily 1.5 Gy and a total dose of 60 Gy. (author)

    International Nuclear Information System (INIS)

    1999-04-01

    Compared to previous programmes, RD and D Programme 98 is focused to a greater extent on method and site selection and on issues relating to the decision-making process. This is natural, since the programme is now approaching the stage where vital decisions will have to be made. The RD and D Programme 98 report is supplemented by a background report 'Detailed Programme for Research and Development 1999-2004' as well as a number of main references 'System Reporting', 'Alternative methods', 'Criteria for Site Evaluation' and the 'North-South/Coast-Interior' report. In addition, a number of references are available in the form of county-specific general siting studies, feasibility studies etc. SKI has distributed RD and D Programme 98 to sixty-three reviewing bodies for comment. The reviewing bodies include universities and institutes of technology, local safety committees, municipalities hosting nuclear facilities and municipalities participating in feasibility studies as well as many authorities. The comments of the reviewing bodies mainly focused on the decision-making process, including issues relating to method selection and site selection and, in particular, on the selection of sites for site investigation. Several reviewing bodies, particularly universities and institutes of technology, have also submitted comments of a more technical-scientific nature. SKI's evaluation has focused on determining whether SKB's programme can be considered to fulfil the requirements stipulated in the Act on Nuclear Activities that such a programme should be able to result in the implementation of solutions for the final disposal of the spent nuclear fuel from the Swedish nuclear power programme. Furthermore, SKI's evaluation has also focused on the conditions that SKI considers should apply to SKB's future work. Specific comments are made for the following areas: Decision-making process, Method selection and system analysis, Siting, Technical development, Safety assessments

    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

    The design principles of MRI main magnets and the problems in the design process have been analyzed. A computer program in which the critical characteristics of superconductor, the uniformity of the magnetic field, the economization of magnet and the selection of magnet constructions are considered has been established. The program can also be used to design high uniformity superconducting magnet in some other uses. In designing MRI superconducting main magnet, five different magnet constructions have been analyzed. Using this computer program the authors made a series of designs of MRI superconducting main magnets with different construction, different central magnetic field, and different bore diameters. By analyzing the computing results some conclusions useful for the practical design of the MRI superconducting main magnets are obtained

    Full Text Available Eugenol is a major volatile constituent of clove essential oil obtained through hydrodistillation of mainly Eugenia caryophyllata (=Syzygium aromaticum buds and leaves. It is a remarkably versatile molecule incorporated as a functional ingredient in numerous products and has found application in the pharmaceutical, agricultural, fragrance, flavour, cosmetic and various other industries. Its vast range of pharmacological activities has been well-researched and includes antimicrobial, anti-inflammatory, analgesic, anti-oxidant and anticancer activities, amongst others. In addition, it is widely used in agricultural applications to protect foods from micro-organisms during storage, which might have an effect on human health, and as a pesticide and fumigant. As a functional ingredient, it is included in many dental preparations and it has also been shown to enhance skin permeation of various drugs. Eugenol is considered safe as a food additive but due to the wide range of different applications, extensive use and availability of clove oil, it is pertinent to discuss the general toxicity with special reference to contact dermatitis. This review summarises the pharmacological, agricultural and other applications of eugenol with specific emphasis on mechanism of action as well as toxicity data.

    Highlights: • Bi_2Se_3 and Ni doped Bi_2Se_3 were synthesized by solvothermal approach. • Presence of nickel was confirmed by X-ray photoelectron spectroscopy (XPS) measurement. • Complete degradation of malachite green (MG) dye was achieved by Ni doped Bi_2Se_3 with H_2O_2. • Remarkable photo-catalytic degradation by doped bismuth selenide has been explained. • Scavenger tests show degradation of MG is mainly dominated by ·OH oxidation process. - Abstract: Bismuth selenide (Bi_2Se_3) and nickel (Ni) doped Bi_2Se_3 were prepared by a solvothermal approach to explore the photo-catalytic performance of the materials in degradation of malachite green (MG). The presence of nickel was confirmed by X-ray photoelectron spectroscopy (XPS) measurement in doped Bi_2Se_3. The results showed that the nickel doping played an important role in microstructure and photo-catalytic activity of the samples. Nickel doped Bi_2Se_3 sample exhibited higher photo-catalytic activity than that of the pure Bi_2Se_3 sample under visible-light irradiation. The photo-catalytic degradation followed first-order reaction kinetics. Fast degradation kinetics and complete (100% in 5 min of visible light irradiation) removal of MG was achieved by nickel doped Bi_2Se_3 in presence of hydrogen peroxide (H_2O_2) due to modification of band gap energies leading to suppression of photo-generated electron-hole recombination.

    The removal of nitrogen-containing compounds (NCCs) from fossil fuels prior to combustion is currently of particular importance, and so we investigated an adsorptive method using metal-organic frameworks (MOFs) for the removal of indole (IND) and quinoline (QUI), which are two of the main NCCs present in fossil fuels. We herein employed an amino (-NH 2 )-functionalized MIL-125 (MIL-125-NH 2 ) MOF, which was further modified by protonation (P-MIL-125-NH 2 ). These modified MOFs exhibited extraordinary performance in the adsorption of both IND (as representative neutral NCC) and QUI (as representative basic NCC). These MOFs were one of the most efficient adsorbents for the removal of NCCs. For example, P-MIL-125-NH 2 showed the highest adsorption capacity for QUI among ever reported adsorbent. The improved adsorption of IND was explained by H-bonding and cation-π interactions for MIL-125-NH 2 and P-MIL-125-NH 2 , respectively, while the mechanisms for QUI were H-bonding and acid-base interactions, respectively. This is a rare phenomenon for a single material (especially not with very high porosity) to exhibit such remarkable performances in the adsorption of both basic QUI and neutral IND. The adsorption results obtained using regenerated MIL-125-NH 2 and P-MIL-125-NH 2 also showed that these materials can be used several times without any severe degradation.

    1997-01-01

    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.

  5. Paradigm, experiment and conclusion: La Casa by Bernard Rudofsky in three acts

    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.

    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.

  7. Pressure Measurement Techniques for Abdominal Hypertension: Conclusions from an Experimental Model.

    2015-01-01

    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.

    2003-10-01

    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.

  9. 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

    Reehorst, Andrew; Brinker, David

    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.

    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.

  13. Total Knee Arthroplasty for Knee Osteoarthritis: Support for a Foregone Conclusion?

    2017-07-01

    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.

    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.))

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

    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.)

  17. 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

    Purpose: In clinical brachytherapy, there is a tendency to replace continuous low-dose-rate (LDR) irradiation by either single-dose or fractionated high-dose-rate (HDR) irradiation. In this study, the equivalence of LDR treatments and fractionated HDR (2 fractions/day) or pulsed-dose-rate (PDR, 4 fractions/day) schedules in terms of tumor cure was investigated in an experimental tumor model. Methods and Materials: Tumors (rat rhabdomyosarcoma R1M) were grown s.c. in the flank of rats and implanted with 4 catheters guided by a template. All interstitial radiation treatment (IRT) schedules were given in the same geometry. HDR was given using an 192 Ir single-stepping source. To investigate small fraction sizes, part of the fractionated HDR and PDR schedules were applied after an external irradiation (ERT) top-up dose. The endpoint was the probability of tumor control at 150 days after treatment. Cell survival was estimated by excision assay. Results: Although there was no fractionation effect for fractionated HDR given in 1 or 2 fractions per day, TCD 50 -values were substantially lower than that for LDR. A PDR schedule with an interfraction interval of 3 h (4 fractions/day), however, was equivalent to LDR. The combination of ERT and IRT resulted in a remarkably increased tumor control probability in all top-up regimens, but no difference was found between 2 or 4 fractions/day. Catheter implantation alone decreased the TCD 50 for single-dose ERT already by 17.4 Gy. Cell viability assessed at 24 h after treatment demonstrated an increased effectiveness of interstitial treatment, but, after 10 Gy ERT followed by 10 Gy IRT (24-h interval), it was not less than that calculated for the combined effect of these treatments given separately. Conclusion: In full fractionation schedules employing large fractions and long intervals, the sparing effect of sublethal damage repair may be significantly counteracted by reoxygenation. During 3-h intervals, however, repair may be

    Pseudosmylidia relicta gen. et sp. nov. (Neuroptera: Osmylidae) is described from the late Eocene of Florissant (U.S.A., Colorado). It is assigned to the subfamily Protosmylinae based on the presence of two venational features characteristic of the subfamily: most crossveins in the radial to intramedial spaces of the forewing are arranged in four gradate series, and CuP is short and simple or forked only once in the hind wing. This genus is remarkable by CuP in the forewing bearing few pectinate branches. This is the only genus of extant and Cenozoic fossil Osmylidae in which this plesiomorphic condition is retained.

    Embodiments of isolators, such as three parameter isolators, including a main spring linear guide system are provided. In one embodiment, the isolator includes first and second opposing end portions, a main spring mechanically coupled between the first and second end portions, and a linear guide system extending from the first end portion, across the main spring, and toward the second end portion. The linear guide system expands and contracts in conjunction with deflection of the main spring along the working axis, while restricting displacement and rotation of the main spring along first and second axes orthogonal to the working axis.

  6. Remark on the role of the driving force in BWR instability

    Dykin, V.; Pazsit, I.

    2009-01-01

    Simple models of BWR instability, used e.g. in understanding the role of the various oscillation modes in the overall stability of the plant, assume that each oscillation mode can be described by a second order system (a damped harmonic oscillator) driven by a white noise driving force. Change of the decay ratio (DR) of the observed signal is, as a rule, associated with the changing of the parameters of the damped oscillator, mainly its damping coefficient, and is interpreted in terms of the change of the stability of the system. However, conceptually, one cannot exclude cases when the change of the response of a driven damped oscillator is due to the change of the properties of the driving force. In this work we investigate the effect of a non-white driving force on the behaviour of the system. A question of interest is how changes of the spectrum of the driving force influence the observed autocorrelation function (ACF) of the resulting signal. Hence we calculate the response of a damped harmonic oscillator driven by a non-white driving force, corresponding to the reactivity effect of propagating density fluctuations in two-phase flow. It is shown how in some special cases such a driving force, when interpreting the neutron noise as if induced by a white noise driving source, can lead to an erroneous conclusion regarding the stability of the system. It is also concluded that in the practically interesting cases the effect of the coloured driving force, arising from propagating density fluctuations, is negligible.

    In September 2004, Nordic Council of Ministers (NCM) in their meeting in Akureyri, Iceland, assessed the state of the Nordic electricity market. The Ministers acknowledged that the market has proved it is well functioning in many respects, however, further development of the Nordic electricity market is needed, i.e. towards a regional market without borders. The Nordic Transmission System Operators (TSOs) were asked to study how a further co-ordination of the system responsibility, a joint organizing and financing of the grid investments and a handling of peak load situations can be established in the Nordic countries. In this report, the main focus is on market-related tasks within system responsibility that are market-related and may have an effect on the functioning of the market. The report covers the following issues: definition of the system responsibility and role of TSOs, harmonization of operational rules and practices in order to improve functioning of the market, TSOs' collaboration in disturbances and shortage situations and joint Nordic transmission investments. Furthermore, the report summarizes the concrete actions taken by the TSOs in strengthening of the market mechanisms in peak load situations. (BA)

    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.

    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. .

    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

  12. 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.

    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.

  14. 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.

    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

    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

    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

    The overall aim of the SARNET (Severe Accident Research NETwork), in the EU 6th Framework programme was to integrate in a sustainable manner the research capabilities of fifty-one European organisations from eighteen member states of the European Union (EU) plus the Joint Research Centres, with one Canadian company, to resolve important remaining uncertainties and safety issues concerning existing and future nuclear plant, especially water-cooled reactors, under hypothetical severe accident conditions. It emphasised integrating activities, spreading of excellence (including knowledge transfer) and jointly executed research, with the knowledge gained being encapsulated in the European severe accident modelling code ASTEC. This paper summarises the achievements over the whole project in the Source Term Topic, which dealt with potential radioactive release to the environment, covering release of fission products and structural materials from the core, their transport in the primary circuit, and their behaviour in the containment. The main technical areas covered, as emphasised by the earlier EURSAFE project, were the effect of oxidative conditions on fission product release and transport (especially the behaviour of the highly radiotoxic ruthenium under air ingress conditions), iodine volatility in the primary circuit, control rod aerosol release (Ag-In-Cd) that affects iodine transport, containment by-pass in the case of steam generator tube rupture, aerosol retention in containment cracks, aerosol remobilisation in the circuit, and iodine/ruthenium behaviour in the containment especially concerning the volatile fraction in the atmosphere. The studies also covered performance of new experiments, analysis of existing data, and formulation and improvement of theoretical models. Significant progress was made in each area. Looking to the future, the 7th Framework successor project SARNET2 covers the remaining issues concerning iodine and ruthenium, including practical

    Full Text Available The Life Project “Monitoring of insects with public participation” (LIFE11 NAT/IT/000252 had as the main objective to develop and test methods for the monitoring of five beetle species listed in the Annexes of the Habitats Directive (92/43/EEC: Osmoderma eremita (hermit beetle, Scarabaeidae, Lucanus cervus (European stag beetle, Lucanidae, Cerambyx cerdo (great capricorn beetle, Cerambycidae, Rosalia alpina (rosalia longicorn, Cerambycidae and Morimus asper/funereus (morimus longicorn, Cerambycidae. The data gathered represent an important contribution to the monitoring of these target species in Italy. The methods developed for monitoring of the target species are intended for use by the local management authorities and staff of protected areas. These developed methods are the result of extensive fieldwork and ensure scientific validity, ease of execution and limited labour costs. The detailed description of methods and the results for each species are published in separate articles of this special issue of Nature Conservation. A second objective of the project was to gather faunistic data with a Citizen Science approach, using the web and a mobile application software (app specifically built for mobile devices. The validation of the records collected by the citizens was carried out by experts, based on photographs, which were obligatory for all records. Dissemination activities represented the principal way to contact and engage citizens for the data collection and also offered the possibility of providing information on topics such as Natura 2000, the Habitats Directive, the role of monitoring in nature conservation, the importance of forest ecosystems and the ecological role of the saproxylic insects. An innovative method tested during the project was the training of a dog for searching and monitoring the elusive hermit beetle; the trained dog also added a “curiosity” factor to attract public attention towards this rare insect and

    The striking resemblance of long-snouted aquatic mammals and reptiles has long been considered an example of morphological convergence, yet the true cause of this similarity remains untested. We addressed this deficit through three-dimensional morphometric analysis of the full diversity of crocodilian and toothed whale (Odontoceti) skull shapes. Our focus on biomechanically important aspects of shape allowed us to overcome difficulties involved in comparing mammals and reptiles, which have fundamental differences in the number and position of skull bones. We examined whether diet, habitat and prey size correlated with skull shape using phylogenetically informed statistical procedures. Crocodilians and toothed whales have a similar range of skull shapes, varying from extremely short and broad to extremely elongate. This spectrum of shapes represented more of the total variation in our dataset than between phylogenetic groups. The most elongate species (river dolphins and gharials) are extremely convergent in skull shape, clustering outside of the range of the other taxa. Our results suggest the remarkable convergence between long-snouted river dolphins and gharials is driven by diet rather than physical factors intrinsic to riverine environments. Despite diverging approximately 288 million years ago, crocodilians and odontocetes have evolved a remarkably similar morphological solution to feeding on similar prey. © 2017 The Author(s).

    Previous research has reported that aspects of social cognition such as nonliteral language comprehension are impaired in adults with Tourette's syndrome (TS), but little is known about social cognition in children and adolescents with TS. The present study aims to evaluate a measure of sarcasm comprehension suitable for use with children and adolescents (Experiment 1), and to examine sarcasm comprehension in children and adolescents with TS-alone or TS and attention deficit hyperactivity disorder (ADHD; Experiment 2). In Experiment 1, the measure of sarcasm comprehension was found to be sensitive to differences in nonliteral language comprehension for typically-developing children aged 10 to 11 years old compared to children aged 8 to 9 years old; the older group performed significantly better on the comprehension of scenarios ending with either direct or indirect sarcastic remarks, whereas the two age groups did not differ on the comprehension of scenarios ending with sincere remarks. In Experiment 2, both the TS-alone and TS+ADHD groups performed below the level of the control participants on the comprehension of indirect sarcasm items but not on the comprehension of direct sarcasm items and sincere items. Those with TS+ADHD also performed below the level of the control participants on measures of interference control and fluency. The findings are discussed with reference to the possible contribution of executive functioning and mentalizing to the patterns of performance.

    This is the concluding remarks in the international symposium on highly excited states in nuclear reactions. The remarks concentrate on the giant quadrupole states. In the framework of the distorted wave Born approximation (DWB), the differential cross section can be deduced. The relevant transition matrix elements are defined, and the quantities which are measured in inelastic hadron (h, h') reactions are shown. These are used to obtain both neutron and proton transition multipole matrix elements. This is equivalent to make the isospin decomposition of the electromagnetic transition matrix elements. The ratios of the transition matrix elements of neutrons and protons of the lowest 2/sup +/ states in even-even single closed shell nuclei are evaluated and compared with experimental results. For each nucleus, the consistency between various measurements is generally good. The effect of the virtual excitation of giant 2/sup +/ states into the ground and first excited states of even-even nuclei is discussed. The accuracy of (h, h') results can be tested.

  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

    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 Global Bio-Energy Partnership (GBEP) has developed a set of 24 sustainability indicators applicable to all forms of bio-energy and aimed at voluntary use by national governments. The GBEP indicators enable governments to assess the bio-energy sector and to develop new policies related to sustainable bio-energy production and use. These indicators have been piloted in Ghana. Modern bio-energy is a big opportunity for the region, which is why NL Agency adopted and supported the pilot, together with the Global Bio-Energy Partnership (GBEP). The pilot project also was supported by the ECOWAS Regional Centre for Renewable Energy and Energy Efficiency (ECREEE) and has been coordinated by the Council for Scientific and Industrial Research (CSIR). The Ghana Energy Commission took the responsibility to involve policymakers. Partners for Innovation was commissioned by NL Agency to provide technical assistance for the pilot. The main aims of the project are: (a) Enhancing the capacity of the host country Ghana (and ECOWAS) to use the GBEP indicators as a tool for assessing the sustainability of its bio-energy sector and/or developing sustainable bio-energy policies; (b) Learning lessons on how to apply the indicators and how to enhance their practicality as a tool for policymakers and giving this as feedback to the GBEP community. Three Ghanaian research institutes (CSIR-FORIG, CSIR-IIR and UG-ISSER) have studied 11 out of the 24 GBEP indicators in the pilot. The pilot has been a success: the 24 sustainability criteria appear to be very valuable for Ghana. As such the indicators provide, also for other governments, a practical tool to assess sustainability of biomass sectors and policies. The report also shows important insights on data availability and quality, and on the applicability of the GBEP indicators in Ghana. The final report provides concrete recommendations on: (1) How Ghana can proceed with the GBEP sustainability indicators; and (2) The lessons learned for

    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.

  9. Severe accident management (SAM), operator training and instrumentation capabilities - Summary and conclusions

    International Nuclear Information System (INIS)

    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.

    2005-01-01

    On September 6-10, 2004 a workshop on 'Safe, Efficient, and Cost-Effective Decommissioning' was held in Rome (Italy) to enable international experts on decommissioning to compare and evaluate respective approaches and experiences in decommissioning nuclear power and fuel cycle facilities and to formulate proposals for future international cooperation in the decommissioning arena. The main messages emerging from the workshop are: - Decommissioning is a mature industrial process and many projects have been safely completed with support of local communities. Technical and scientific issues are well-understood and practical experience and associated lessons are being documented to guide future activities. Emphasis is being placed on effective planning with active programmes of community involvement. - Individual countries need to further develop integrated decommissioning and waste management strategies to ensure that long-term solutions will be available for all wastes generated from decommissioning. National systems are evolving to meet national needs, against a framework provided by the international organisations, and these seem increasingly to favour early dismantling regardless of the availability of waste disposal routes. - Realistic and streamlined regulatory programmes are being developed with feed back from industry experience and are placing more responsibility and accountability on licensees. - Accurate decommissioning waste cost calculation methods is needed. Waste volumes may vary from project to project even for similar installations. There though appears to be a strong case for accumulating data and benchmarking costs for similar plants and processes. Further work and experience exchange on cost comparisons between different strategies (for example clearance and recycling/reuse of materials versus direct surface disposal) would be valuable. - International clearance criteria have been established, with individual countries free to adopt them

    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

    The first-offer effect demonstrates that negotiators achieve better outcomes when making the first offer than when receiving it. The evidence, however, primarily derives from studies of Westerners without systematic power differences negotiating over one issue-contexts that may amplify the first-offer effect. Thus, the present research explored the effect across cultures, among negotiators varying in power, and in negotiations involving single and multiple issues. The first two studies showed that the first-offer effect remains remarkably robust across cultures and multi-issue negotiations. The final two studies demonstrated that low-power negotiators benefit from making the first offer across single- and multi-issue negotiations. The second and fourth studies used multi-issue negotiations with distributive, integrative, and compatible issues, allowing us to show that first offers operate through the distributive, not the integrative or compatible issues. Overall, these results reveal that moving first can benefit negotiators across many organizational and personal situations.

    Since its introduction in 2001, natural time analysis has been applied to diverse fields with remarkable results. Its validity has not been doubted by any publication to date. Here, we indicate that frequently asked questions on the motivation and the foundation of natural time analysis are directly answered if one takes into account the following two key points that we have considered as widely accepted when natural time analysis was proposed: first, the aspects on the energy of a system forwarded by Max Planck in his Treatise on Thermodynamics; second, the theorem on the characteristic functions of probability distributions which Gauss called Ein Schönes Theorem der Wahrscheinlichkeitsrechnung (beautiful theorem of probability calculus). The case of the time series of earthquakes and of the precursory Seismic Electric Signals are discussed as typical examples.

    Integrity assessment of pipelines is part of a process that aims to enhance the operating safety of pipelines. During this task, questions related to the interpretation of inspection reports and the way of regarding the impact of several parameters on the pipeline integrity normally come up. In order to satisfactorily answer such questions, the integrity assessment team must be able to suitably approach different subjects such as corrosion control and monitoring, assessment of metal loss and geometric anomalies, and third party activities. This paper presents additional remarks on some of these questions based on the integrity assessment of almost fifty pipelines that has been done at PETROBRAS/E and P Bahia over the past eight years.

    In the extension of the Dimopoulos-Hall-Raby model of the fermion mass matrices to the neutrino sector, there is an entry in the up-quark and neutrino Dirac mass matrices which can be assumed to arise from the Yukawa coupling of a 120, instead of a 10 or a 126, of SO(10). Although this assumption leads to an extra undetermined complex parameter in the model, the resulting lepton mixing matrix exhibits the remarkable feature that the ν τ does not mix with the other two neutrinos. Making a reasonable assumption about the extra parameter, we are able to fit the large-mixing-angle MSW solution of the solar-neutrino problem, and we obtain m ντ ∼10 eV, the right mass range to close the Universe. Other possibilities for explaining the solar-neutrino deficit are also discussed

    In this paper the linearization of the equations governing the behavior of large-scale interconnected electric power systems is carried out. It is shown that the perturbed equations of motion represent a linear, nonconservative dynamical system with arbitrary parameter matrices. Simplified conditions for the derivability of such systems from a Lagrangian are given. First integrals are derived when a certain commutativity relation is satisfied. It is shown that previously obtained results can be recovered as special cases of the present development. An example in which independent energy-like integrals are obtained by utilizing the results of this paper is given. Finally, a remark contained in a previous paper by the authors is clarified

    A non-Hermitian random matrix model proposed a few years ago has a remarkably intricate spectrum. Various attempts have been made to understand the spectrum, but even its dimension is not known. Using the Dyson-Schmidt equation, we show that the spectrum consists of a non-denumerable set of lines in the complex plane. Each line is the support of the spectrum of a periodic Hamiltonian, obtained by the infinite repetition of any finite sequence of the disorder variables. Our approach is based on the 'theory of words'. We make a complete study of all four-letter words. The spectrum is complicated because our matrix contains everything that will ever be written in the history of the universe, including this particular paper

    Coastal urbanization is rapidly expanding worldwide while its impacts on seaweed communities remain poorly understood. We assessed the impact of urbanization along an extensive latitudinal gradient encompassing three phycogeographical regions in the SW Atlantic. Human population density, number of dwellings, and terrestrial vegetation cover were determined for each survey area and correlated with diversity indices calculated from seaweed percent cover data. Urban areas had significantly lower calcareous algal cover (-38%), and there was significantly less carbonate in the sediment off urban areas than off reference areas. Seaweed richness averaged 26% less in urban areas than in areas with higher vegetation cover. We observed a remarkable decline in Phaeophyceae and a substantial increase of Chlorophyta in urban areas across a wide latitudinal gradient. Our data show that coastal urbanization is causing substantial loss of seaweed biodiversity in the SW Atlantic, and is considerably changing seaweed assemblages. Copyright © 2013 Elsevier Ltd.

    1997-01-01

    We created a self-study program using HTML browser on the Clinical Nursing General Remarks Course, Eighty-three students each selected a published book on a personal history (written personal reflections from individuals who had undergone medical treatment and hospitalization), read it and submitted reports of their impressions of the histories. Their reports were arranged from a nursing perspective and entered on the home page of our college using HTML browser. We intended that the students would become more interested in reading of the personal histories, and that they would acquire new self-study skills and increase their interest in Internet through use of our program. In addition, we hoped that this program would encourage positive communication and mutual sharing of information. The students were able to easily refer to a personal history according to their interest from a nursing perspective. Therefore this program realized the mutual learning among students and other users.

    We are in a remarkable period of discovery in GRB astronomy. The current satellites including Swift, Fermi. AGILE and INTEGRAL are detecting and observing bursts of all varieties. Increasing capabilities for follow-up observations on the ground and in space are leading to rapid and deep coverage across the electromagnetic spectrum, The future will see continued operation of the current experiments and with future missions like SVOM plus possible rni_Ssions like JANUS and EXIST. An exciting expansion of capabilities is occurring in areas of gravitational waves and neutrinos that could open new windows on the GRB phenomenon. Increased IR capabilities on the ground and with missions like JWST will enable further exploration of high redshift bursts. The future is bright.

  6. Remarkable identities related to the (quantum) elliptic Calogero-Sutherland model

    2006-01-01

    We present remarkable functional identities related to the elliptic Calogero-Sutherland (eCS) system. We derive them from a second quantization of the eCS model within a quantum field theory model of anyons on a circle and at finite temperature. The identities involve two eCS Hamiltonians with arbitrary and, in general, different particle numbers N and M, and a particular function of N+M variables arising as anyon correlation function of N particles and M antiparticles. In addition to identities obtained from anyons with the same statistics parameter λ, we also obtain 'dual' relations involving 'mixed' correlation functions of anyons with two different statistics parameters λ and 1/λ. We also give alternative, elementary proofs of these identities by direct computations

  7. A remarkable representation of the SO(3,2) Kac-Moody algebra

    Dobrev, V.K.; Sezgin, E.

    1990-01-01

    We construct a minimal representation of the SO(3,2) Kac-Moody algebra algebra which is based on the spin-zero singleton (the Rac) representation of SO(3,2). The representation is minimal in the sense that the central charge k of the SO(3,2) Kac-Moody algebra is chosen to take the special value of 5/2 which allows the imposition of maximum number of reducibility conditions. For the Rac, this is the unique choice for the remarkable property of maximum reducibility which is consistent with unitarity. To ensure unitarity, we furthermore impose invariance condition under the maximal compact subalgebra SO(3) x SO(2). (author). 19 refs, 1 fig

    In 27 patients with no radiographic evidence of injury, spinal cord injury was depicted as low signal intensity on MRI. In 4 patients who had spontaneous reduction of the anterior dislocation, remarkable instability was observed. Among the other 23 patients, two patients had each two injured sites, and the remaining patients had only one injuried site. Injured sites were not correlated with the development of spondylosis or the antero-posterior diameter of the spinal canal, but well correlated with ossification of the posterior longitudinal ligament. Many of the patients had surgical evidence of horizontal rupture of the anterior longitudinal ligament and intervertebral disk. In these cases, although the spinal cord was instable at the level of extension, it was stable at the level of midline flection. Excessively extended injury with no associated anterior longitudinal ligament was considered attributable to the strictured spinal canal. (Namekawa, K)

    A 72-year-old woman developed adenocarcinoma of the left parotid gland. Because of the excessive size of her tumor and the fact that she suffered from severe liver dysfunction, she was treated by hyperthermo-chemo-radiotherapy (HCR therapy). After ten sessions of radiofrequency hyperthermia with HEH 500 (13.56 MHz radiofrequency wave), 50-Gy irradiation from a linac and administration of 33.0 g of tegafur in suppository form, the tumor mass showed remarkable regression decreasing in size by as much as 84 % on computed tomography. Histologically, the tumor which was resected under local anesthesia, showed almost total necrosis. The multidisciplinary HCR therapy was well tolerated and effective as a therapy for cancer in this case. (author)

  10. REMARKS ON NEUROCONTROL OF THE HAND AND SIGNIFICANCE OF AFFERENT INPUT

    2004-12-01

    Full Text Available This paper outlines some remarks on our understanding of motor control of the hand. It begins with current knowledge about motor behavior of prehension movements. It further highlights the distributed nature of the control system that integrates sensory information from the periphery, existing motor memory from subcortical centers, and information from diverse primary and secondary motor as well as sensory areas. It further explains the sequential nature of the processes like decision, planning, computing, and execution involved in neurocontrol of a purposeful hand motor task. In the successive part it stresses the importance of sensory input, in particular proprioceptive, for movement setting and guidance. It concludes by pointing out research concepts used to study roles of sensory information for modulating states of neurobiological systems. Finally, a novel method of whole hand electrical stimulation, which seems promising as a tool for studying sensory-motor integration mechanisms in human’s hand, is explained and recent experimental data are provided.

    Arctic sea ice loss may influence midlatitude climate by changing large-scale circulation. The extent to which climate change can be understood as greenhouse gas-induced changes that are modulated by this loss depends on how additive the responses to the separate influences are. A novel sea ice nudging methodology in a fully coupled climate model reveals that the separate effects of doubled atmospheric carbon dioxide (CO2) concentrations and associated Arctic sea ice loss are remarkably additive and insensitive to the mean climate state. This separability is evident in several fields throughout most of the year, from hemispheric to synoptic scales. The extent to which the regional response to sea ice loss sometimes agrees with and sometimes cancels the response to CO2 is quantified. The separability of the responses might provide a means to better interpret the diverse array of modeling and observational studies of Arctic change and influence.

  12. Remarkable Diversity of Escherichia coli Carrying mcr-1 from Hospital Sewage with the Identification of Two New mcr-1 Variants

    Full Text Available The plasmid-borne colistin-resistant gene mcr-1 has rapidly become a worldwide public health concern. This study aims to determine the host bacterial strains, plasmids, and genetic contexts of mcr-1 in hospital sewage. A 1-ml hospital sewage sample was cultured. Colistin-resistant bacterial colonies were selected on agar plates and were subjected to whole genome sequencing and subsequent analysis. The transfer of mcr-1 between bacterial strains was tested using conjugation. New variants of mcr-1 were cloned to test the impact of variations on the function of mcr-1. Plasmids carrying mcr-1 were retrieved from GenBank for comparison based on concatenated backbone genes. In the sewage sample, we observed that mcr-1 was located in various genetic contexts on the chromosome, or plasmids of four different replicon types (IncHI2, IncI2, IncP, and IncX4, in Klebsiella pneumoniae, Kluyvera spp. and seven Escherichia coli strains of six different sequence types (ST10, ST34, ST48, ST1196, ST7086, and ST7087. We also identified two new variants of mcr-1, mcr-1.4 and mcr-1.7, both of which encode an amino acid variation from mcr-1. mcr-1-carrying IncX4 plasmids, which have a global distribution across the Enterobacteriaceae, are the result of global dissemination of a single common plasmid, while IncI2 mcr-1 plasmids appear to acquire mcr-1 in multiple events. In conclusion, the unprecedented remarkable diversity of species, strains, plasmids, and genetic contexts carrying mcr-1 present in a single sewage sample from a single healthcare site highlights the continued evolution and dynamic transmission of mcr-1 in healthcare-associated environments.

  14. Reactor and /or accelerator: general remarks on strategic considerations in sourcing/producing radiopharmaceuticals and radiotracer for the Philippines

    Nazarea, A.D.

    The most important sources of radionuclides in the world are particle accelerators and nuclear reactors. Since the late 1940's many radiotracers and radiopharmaceuticals have been innovated and conceived, designed, produced and applied in important industrial and clinical/ biomedical settings. For example in the health area, reactor-produced radionuclides have become indispensable for diagnostic imaging involving, in its most recent and advanced development, radioimmunoscintigraphy, which exploits the exquisite ligand-specificity of monoclonal antibodies, reagents which in turn are the products of advances in biotechnology. Thus far, one of the most indispensable radiopharmaceuticals has been 99m Tc, which is usually obtained as a daughter decay product of 99 Mo. In January 1991, some questions about the stability of the worldwide commercial supply of 99 Mo became highlighted when the major commercial world producer of 99 Mo, Nordion International, shut down its facilities temporarily in Canada due to contamination in its main reactor building (see for instance relevant newsbrief in J. Nuclear Medicine (1991): 'Industry agrees to join DOE study of domestic moly-99 production'). With the above background, my remarks will attempt to open discussions on strategic considerations relevant to questions of 'self reliance' in radiotracers/radiopharmaceutical production in the Philippines. For instance, the relevant question of sourcing local radionuclide needs from a fully functioning multipurpose cyclotron facility within the country that will then supply the needs of the local industrial, biomedical (including research) and health sectors; and possibly, eventually acquiring the capability to export to nearby countries longer-lived radiotracers and radiopharmaceuticals

  16. Characteristics of fluctuating pressure generated in BWR main steam lines

    Takahashi, Shiro; Okuyama, Keita; Tamura, Akinori

    2009-01-01

    The BWR-3 steam dryer in the Quad Cities Unit 2 Nuclear Power Plant was damaged by high cycle fatigue due to acoustic-induced vibration. The dryer failure was as attributed to flow-induced acoustic resonance at the stub pipes of safety relief valves (SRVs) in the main steam lines (MSLs). The acoustic resonance was considered to be generated by interaction between the sound field and an unstable shear layer across the closed side branches with SRV stub pipes. We have started a research program on BWR dryers to develop their loading evaluation methods. Moreover, it has been necessary to evaluate the dryer integrity of BWR-5 plants which are the main type of BWR in Japan. In the present study, we used 1/10-scale BWR tests and analyses to investigate the flow-induced acoustic resonance and acoustic characteristics in MSLs. The test apparatus consisted of a steam dryer, a steam dome and 4 MSLs with 20 SRV stub pipes. A finite element method (FEM) was applied for the calculation of three-dimensional wave equations in acoustic analysis. We demonstrated that remarkable fluctuating pressures occurred in high and low frequency regions. High frequency fluctuating pressures was generated by the flow-induced acoustic resonance in the SRV stub pipes. Low frequency fluctuating pressure was generated in an MSL with the dead leg. The frequency of the latter almost coincided with the natural frequency of the MSL with the dead leg. The amplitude of the fluctuating pressures in the multiple stub pipes became more intense because of interaction between them compared with that in the single stub pipe. Acoustic analysis results showed that the multiple stub pipes caused several natural frequencies in the vicinity of the natural frequency of the single stub pipe and several modes of the standing wave in the MSLs.

  17. Reframing the science and policy of nicotine, illegal drugs and alcohol - conclusions of the ALICE RAP Project.

    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.

    1989-01-01

    The main control room at a nuclear power station must remain habitable during a variety of plant conditions and postulated events. The control room habitability requirement and the function of the heating, ventilating, air-conditioning, and air treatment system are to control environmental factors, such as temperature, pressure, humidity, radiation, and toxic gas. Habitability requirements provide for the safety of personnel and enable operation of equipment required to function in the main control room. Habitability as an issue has been gaining prominence with the Advisor Committee of Reactor Safeguards and the Nuclear Regulatory Commission since the incident at Three Mile Island. Their concern is the ability of the presently installed habitability systems to control the main control room environment after an accident. This paper discusses main control room HVAC systems; the concern, requirements, and results of NRC surveys and notices; and an approach to control room habitability reviews
